Description

Head-up display welding helmet with wireless module

technical field

The present invention generally relates to a head-up display welding mask equipped with a wireless module.

Background technique

During the welding operation, in order to protect the operator from being hurt by spatter and various harmful rays generated by arcing, the operator usually wears a welding mask. In a traditional welding mask, the optical filter is a key component to protect the operator's eyes from harmful rays. Traditional welding masks require the operator to observe the welding arc starting position before wearing the mask, and then wear the mask for blind operation. This kind of blind operation will bring a lot of inconvenience in the field construction process.

To this end, self-darkening welding helmets have been developed in recent years. Such auto-darkening welding helmets are generally equipped with an auto-darkening filter. The main principle of the automatic darkening filter is to equip a liquid crystal panel, which is transparent before the welding arc is started, and the liquid crystal panel changes to an opaque state at the moment of arcing, so as to provide protection for the operator's eyes. Usually this automatic darkening filter is equipped with an adjustment knob or button. Before using the welding mask, the operator must take off the mask to adjust the operating parameters of the automatic darkening filter such as sensitivity, delay time, shading number, welding method, etc. Then wear the upper mask for welding operation. In some welding work sites that require repeated changes in operating parameters (such as changing welding methods, adjusting sensitivity, etc.), repeated removal/wearing of masks greatly consumes the operator's physical strength and affects welding quality.

In addition, during the process of removing the mask, setting parameters, and putting on the mask again, the operator's eyes need to constantly adjust to adapt to the changes in the surrounding light and dark environment, which may even cause serious discomfort to individual operators, thereby affecting the welding work. Seriously, it may even cause permanent damage to the eyes.

Taking the argon arc welding machine as an example, modern welding equipment generally includes electric welding machines, gas cylinders, welding torches and welding masks. Before welding, it is usually necessary to set the current, voltage, welding duration, wire feeding speed and other parameters of the electric welding machine accordingly, and there will be a display on the operation panel of the electric welding machine to display the parameter settings accordingly. The electric welding machine and the welding mask are connected via a cable, so that after the parameters of the electric welding machine and the welding mask are set, the operator starts to work wearing the welding mask.

Such a connection cable between the electric welding machine and the welding helmet may trip the operator while performing the welding work. In addition, limited by the length of the cable, it may restrict the welding work of the operator in a specific environment. In addition, due to the harsh environment of the welding site, the connection cable may be aged or broken due to frequent looping after long-term use, resulting in poor signal connection and affecting the normal use of the welding mask.

Utility model content

The utility model aims to propose an improved automatic darkening welding mask, whereby the operator can set the operating parameters of the automatic darkening filter without repeatedly taking off/wearing the mask, reducing the operator's awareness of the external light and dark environment. The discomfort caused by constant adjustment and adaptation, and at the same time, the operator can always maintain the wearing posture and adjust various operating parameters, which brings convenience to the welding work. In addition, this improved automatic darkening welding mask is also equipped with a wireless transmission module, which is used to receive and display various operating parameter information of the electric welding machine of the welding equipment, so that the operating parameters of the electric welding machine can be directly observed by the operator wearing the mask , which is convenient for the operator to observe, while avoiding the probability of the operator being injured during the welding operation. In addition, the operating parameters of the electric welding machine are not limited by the length of the cable and are intuitively displayed on the welding mask, which can help the operator to monitor and/or adjust in real time The status of the welding machine.

Detailed ways

In the various figures of the application, structurally identical or functionally similar features are indicated by the same reference numerals.

According to the head-up display (HUD for short) automatic dimming filter of the present invention, the operator can set various operating parameters of the automatic dimming filter without removing the mask. As shown in FIG. 1 , the automatic darkening filter 10 includes a liquid crystal filter lens group 10 a, a solar cell group 10 b, and a head-up display 10 c.

A liquid crystal filter lens group 10a, a solar cell group 10b are located on the main body of the automatic darkening filter 10, and a head-up display 10c is obliquely disposed under the main body. The head-up display 10c is a liquid crystal display, on which all operating parameters related to the auto-dimming filter 10 can be displayed in good time.

It should be pointed out that, except for the head-up display 10c and the content described below, the basic principle of the automatic darkening filter 10 is basically similar to the automatic darkening filters currently on the market, so the automatic darkening filter 10 itself The description of the working principle is omitted here.

A control knob 30 is connected to the auto-darkening filter 10 via a control cable for adjusting its operating parameters. Here, the adjustment of the operating parameters may include adjustment of the shade number (SHADE) of the automatic darkening filter 10, gears 9-13; sensitivity adjustment (SENSITIVITY), gears 0-10; delay time adjustment, gears 0-10; Operation mode adjustment: welding (WELD), cutting (CUTTING) and grinding (GRIND). These operating parameters can be displayed in reverse image on the head-up display 10c.

It should be pointed out that, in the context of the present utility model, for each character or letter or number to be displayed, "reverse image" means that these characters or letters or numbers are displayed on the head-up display 10c in reverse up and down and left and right mirror images superior. In addition, the head-up display 10c can be a monochrome liquid crystal display or a color liquid crystal display or any suitable display device that can be imagined by those skilled in the art.

A glass screen 20 is arranged in front of the automatic darkening filter 10 . The glass screen 20 is light-transmissive, especially transparent, so as not to have any negative effect on the operational function of the automatic darkening filter 10 and at the same time provides additional protection for the automatic darkening filter 10 from welding The resulting flying debris damage. The head-up display 10c is arranged obliquely toward the glass screen 20 on the light-emitting surface below the auto-dimming filter 10, so that when the head-up display 10c is illuminated and displayed, the light is emitted obliquely upward, and part of the light passes through the glass screen 200 and part of it is reflected by the glass screen 20 To the human eye, as shown in FIG. 2, it seems that a magnified positive virtual image of the operating parameters is provided for the human eye at a distance in front of the glass screen 20, so that the operator can conveniently observe the 10 related to various operating parameters.

Fig. 3 schematically shows the basic control block diagram of the head-up display automatic dimming filter. As shown in Figure 3, a battery is connected with the liquid crystal filter lens group 10a via a control circuit, and the knob 30 is also connected with the liquid crystal filter lens group 10a via the control circuit, thereby adjusting the automatic dimming filter 10 through the knob 30 various operating parameters. It should be clear that the battery, control circuit, liquid crystal filter lens set 10a and knob 30 (surrounded by the dotted box in FIG. 3 ) are basically the same design as the prior art automatic darkening filter. According to the utility model, the head-up display 10c is connected with the control circuit. When the operator desires to adjust various operating parameters of the automatic darkening filter 10, the control circuit can control the head-up display 10c to display the corresponding control parameters in a reverse image mode, and The real-time power level of the battery can also be displayed on the head-up display 10c. It can be seen from this point that the head-up display automatic dimming filter according to the present invention can be realized through simple modification on the basis of the existing automatic dimming filter without increasing the manufacturing cost too much.

In addition, the glass screen 20 can be a transparent plexiglass screen or an ordinary glass screen, and at the same time, in order to improve the reflectivity, a reflective film can be attached on the glass screen 20, such as the common reflective film on the car or even the glass screen 20 can be made into a dark and transparent Glass screen, in order to provide a clearer enlarged positive virtual image display in an environment with sufficient external light. Even, the glass screen 20 may be a transparent protective sheet used to protect the darkening filter on a conventional auto-darkening welding helmet. In addition, the head-up display 10c is not limited to be arranged obliquely below the liquid crystal filter lens group 10a as shown in FIG. ground layout. That is to say, any position where the light emitted by the HUD 10c can be projected onto the glass screen 20 can be adopted by the HUD 10c.

Fig. 4 shows a head-up display welding helmet 1 according to an embodiment of the present invention, which is equipped with a head-up display automatic darkening filter 10 according to the present invention. Further referring to FIG. 5 , it can be seen that the welding helmet 1 includes a mask shell 40 , a head-up display type automatic darkening filter 10 mounted on the front of the mask shell 40 , and a headband structure 60 . The headband structure 60 is used to be directly worn on the operator's head, and plays a role of fixing the mask shell 40 . A substantially rectangular opening 40 a is opened at the front of the mask shell 40 , and the support frame 50 is mounted in the opening 40 a. The above-mentioned head-up display type automatic dimming filter 10 is installed on the support frame 50, so that after the support frame 50 is fixed on the mask shell 40, the light-emitting surface of the head-up display 10c of the automatic dimming filter 10 is as shown in the figure 4 is facing obliquely upward.

The knob 30 for adjusting the automatic darkening filter 10 is provided on the mask shell 40 , which is convenient for the operator wearing the mask 1 to directly operate the knob 30 by hand to perform parameter adjustment operations. The transparent protective sheet 20 ′ is arranged in front of the automatic darkening filter 10 at the opening 40 a of the mask shell 40 . It should be clear that the transparent protective sheet 20' may be a glass screen 20 as shown in FIGS. 1 and 2 . The distance between the transparent protective sheet 20' and the automatic darkening filter 10, especially the liquid crystal filter lens group 10a, and the inclination of the obliquely arranged head-up display 10c are set so that the lower head-up display 10c sees through the transparent protective sheet when it emits light 20' creates a virtual image that is just observable by the mask wearer's eyes.

The installation structure of the automatic darkening filter 10 in the mask shell 40 is schematically introduced below. As shown in Figs. 5 and 6, the supporting frame 50 is generally in the form of a rectangular frame having a flange 50a extending inwardly on its side close to the wearer's head. The flange 50a has a bent shape consistent with the main body of the automatic dimmer 10 and its head-up display 10c, so that the main body of the automatic dimmer 10 and its head-up display 10c can fit on the flange 50a exactly. On the lower side of the support frame 50 is provided a support flange 50 b for abutting upward against the head-up display 10 c to prevent the automatic dimmer 10 from falling out of the support frame 50 . It should be clear that the automatic darkening filter 10 can be fixed on the supporting frame 50 by any suitable means known to those skilled in the art, such as adhesive, screw connection structure, crimping structure, locking structure and the like.

The periphery of the opening 40a of the mask shell 40 is formed with two flanges 40a and 40b. The support frame 50 is fitted on the flange 40a via its front flange 50c, and then the protection sheet 20' is placed between the flange 40b and the support frame 50 in the front-rear direction, through the clamp between the flange 40b and the support frame 50. Hold and fix the protection sheet 20'. It should be clear that the protective sheet 20' can be fixed between the support frame 50 and the mask shell 40 in the opening 40a of the mask shell 40 by any suitable fixing method such as bonding, screw connection structure, crimping structure, locking structure, etc. between.

When using the above-mentioned welding mask 1 of the present utility model, the operator can first wear the welding mask 1 on the head, then turn on the adjustment knob 30, and display various parameter information via the transparent protective sheet 20' into a virtual image through the head-up display 10c. in front of the operator's eyes. In this way, after adjusting the operating parameters, the operator can directly start arc welding without taking off/rewearing the mask as in the prior art, which significantly reduces labor intensity and improves work efficiency. In addition, with the welding mask 1 of the present utility model, the operator can directly adjust or check various operating parameters of the automatic darkening filter without taking off the mask, so that the eyes do not need to adapt to the light and shade changes in the surrounding environment, which reduces the discomfort of the eyes , providing further reliable protection for the operator's eyes.

Although in the illustrated embodiment, the head-up display 10c is integrally designed with the body carrying the liquid crystal filter lens assembly 10a and the solar battery assembly 10b. However, it should be clear to those skilled in the art that the head-up display 10c can also be designed separately from the main body of the auto-dimming filter 10 . For example, as an alternative, the head-up display 10c may be manufactured separately from the body of the auto-dimming filter 10, and then connected to the body of the auto-dimming filter 10 and the knob 30 respectively via data cables. In this way, the arrangement position of the head-up display 10c in the mask shell 40 can be selected more conveniently, for example, it can be selected to be arranged at a position that is more favorable for forming a virtual image. In addition, as an alternative, the head-up display 10c can also be arranged on the left side or right side or even above the body of the automatic darkening filter 10, as long as it is ensured that the head-up display 10c can be properly formed into a virtual image by the wearer when tilted toward the protective sheet 20'. Just observe it.

In addition, as mentioned above, the transparent protective sheet 20' in the mask 1 can be the glass screen 20 shown in FIGS. 1 and 2 . However, since the spatter will directly collide with the protective sheet 20' or the glass screen 20 during the welding process to cause surface abrasion, which will cause unclear imaging and affect the observation of operating parameters, so the protective sheet 20' or the glass screen 20 can be detachable. The way is installed on the mask shell 40. For example, alternatively, a plurality of detachable locking structures may be provided on the mask shell 40 around the opening 40 a to detachably lock the protective sheet 20 ′ or the glass screen 20 on the mask shell 40 . In this way, if the protective sheet 20 ′ or the glass screen 20 is excessively worn and affects observation, a new protective sheet 20 ′ or glass screen 20 can be replaced. For another example, it is even possible to use screws to fix the protective sheet 20 ' or the glass screen 20 on the mask shell 40 by perforating the protective sheet 20 ' or the glass screen 20 and the mask shell 40, so that when needed, directly The new protective sheet 20' or glass screen 20 can be replaced by loosening the screws. In a word, any detachable fixing structure conceivable by those skilled in the art can be adopted between the protective sheet 20 ′ or the glass screen 20 and the mask shell 40 .

In addition, the protective sheet 20' can also be made translucent or dark, so as to further provide guarantee for clear imaging. In addition, the protective sheet 20 ′ can also be a protective sheet of a common auto-darkening filter welding mask, which can be used as a reflective screen of a head-up display by attaching a light-transmitting reflective film on its outer surface. In this way, when the image is blurred due to welding spatter after being used for a period of time, the image can be clearly imaged again only by tearing off the old film and attaching a new film.

Different from the welding masks in the prior art, the operator can directly wear the welding mask according to the utility model, and then adjust the parameters by manually adjusting the knob after the head-up display is turned on to image the operating parameters in front of the protective sheet; After the monitor is turned off, the arc can be started directly for welding operation. In addition, in the process of welding operation, in order to change the operating parameters or change the welding mode, the head-up display can be turned on again when the automatic darkening filter is in a transparent state, and various operating parameters are adjusted accordingly, and then the arc is started again for welding operation. It can be seen that, by adopting the welding mask equipped with the head-up display type automatic darkening filter of the present utility model, the operator does not need to take off the mask, adjust parameters, and then wear the mask as in the prior art, and can directly wear the mask. The mask adjusts related operating parameters, while improving work convenience, it ensures that the eyes will not feel uncomfortable due to rapid changes in ambient light, thus improving work efficiency. In addition, with the head-up display welding mask of the present invention, the operator is especially suitable for welding in a dark environment—because the image formed by the head-up display is clearer at this time.

Further referring to FIGS. 3 , 4 and 7 , an embodiment of the welding equipment equipped with the above-mentioned head-up display welding helmet of the present invention will be introduced. The welding equipment includes an electric welder 300 , a gas cylinder 400 (such as an argon gas cylinder), a welding torch 500 and a head-up display type welding helmet 1 . The welding machine 300 , the gas cylinder 400 and the welding torch 500 are connected via cables known in the art. A wireless communication module 100 a is provided on the welding machine 300 . The wireless communication module 100a is connected to the electric welding machine circuit 301, and can be used to send out signals related to the operating parameters of the electric welding machine, such as current size, voltage size, DC or AC display, and working time of the welding torch, and can be used after receiving the control command. Corresponding settings are made to the electric welding machine circuit, thereby correspondingly changing the above-mentioned operating parameters of the electric welding machine.

A wireless communication module 100b is also provided on the head-up display welding helmet 1 of the present invention. For example, as shown in FIG. 4 , the wireless communication module 100 b is disposed on the mask shell 40 above the protective sheet 20 ′ or the glass screen 20 . It should be clear to those skilled in the art that the wireless communication module 100b can also be arranged on any part of the mask shell 40 that will not affect signal transmission or reception. The wireless communication module 100b is mounted on the outer surface of the mask shell as a separate accessory. However, as an alternative, the wireless communication module 100b can also be integrated with the automatic darkening filter 10 in advance.

The wireless communication module 100b can be connected with the control circuit for controlling the head-up display 10c as shown in FIG.

The wireless communication modules 100a and 100b can be wireless networking technology-based (WIFI) modules, bluetooth modules, infrared communication modules or any other communication modules that can realize wireless data connection. In this way, various operating parameters of the welding machine 300 can be imaged on the glass screen 20 via the wireless communication modules 100a and 100b and the head-up display 10c in real time. Specifically, various operating parameters of the electric welder 300 can be imaged in a manner similar to that shown in FIG. 2 . In order to save space, it will not be repeated here.

For example, after the operator wears the welding mask 1, the operating parameters of the automatic darkening filter 10 and the welding machine 300 can be imaged on the glass screen 20 via the wireless communication modules 100a and 100b at the same time, which is convenient for the wearer to observe. Then, the operator presses the knob 30 once and rotates the knob 30 so that a highlight appears on the virtual image corresponding to a corresponding one of the operating parameters such as current. Then, the knob 30 can be rotated after being pressed again so as to increase or decrease the magnitude of the current parameter. After the current size is selected, press the knob 30 again to complete the adjustment. The above only introduces an exemplary embodiment of adjusting the operating parameters through the operation of the knob 30 . It should be clear to those skilled in the art that other suitable implementations of the knob 30 can be redesigned after understanding the corresponding principles.

For the above-mentioned welding mask equipped with a wireless communication module of the utility model, the operator is no longer limited by the cable between the welding mask and the electric welding machine in the prior art, avoiding any constraints during welding work, At the same time, the operating parameters of the electric welding machine can be observed by the operator in real time and adjusted accordingly, which is convenient for the operator to adjust the operating parameters of the electric welding machine at any time according to the construction welding requirements, and improves the work efficiency.

While specific embodiments of the invention have been described in detail herein, they have been presented for purposes of illustration only and should not be considered limiting of the scope of the invention. Various alternatives, changes and modifications can be conceived without departing from the spirit and scope of the invention.
