The welding head is capable of any kinds of welding machine.
Description
Technical field
The present invention relates to a kind of welder head, being applicable to needs accurately to control the welding machine that weld force is carried out accurate welding.
Background technology
All electric resistance welding welding machines all will be provided with welding current, weld interval and three welding parameters of weld force.The conventional art weld force all is that spring is set and control by compressing, because the structure of spring and process technology decision, when many same specification springs compressed same distance, the error of every spring compression stress was bigger; Even the same identical distance of spring compression, but compression stress each time also has difference, that is to say, and the accuracy of spring force is relatively poor.And the manufacturing of instrument, instrument and miniature electronic components and parts, the thickness of welding work pieces is often less than 0.1mm; The repairing of printed substrate, the welding of solar cell, the thickness of workpiece is thinner, even less than 0.05mm, carry out such precision welding, must accurately control weld force.Obviously, set and control the instructions for use that weld force does not satisfy accurate welding with the compression spring.
Summary of the invention
The purpose of this invention is to provide a kind of welder head, can accurately set, control and show weld force, be applicable to that various need accurately control the welding machine of weld force.
To achieve these goals, the present invention is equipped with pressure sensor in welder head.Pressure sensor is generally rectangular structure, and an end of cuboid pressure sensor is connected with the device that transmits weld force, and the other end directly or indirectly is connected with welding head holder, and soldering tip is installed on the welding head holder; Pressure sensor is connected with the pressoreceptor signal processing circuit by the pressure sensor lead-out wire.
Adopts pressure sensor control weld force, simple in structure and accuracy is high, relative error can reach 1 ‰.The welder head of band pressure sensor of the present invention can be assemblied in any type welding machine that needs accurately to control in the weld force welding machine.
Below in conjunction with accompanying drawing the present invention is described in further detail.
Description of drawings
Fig. 1 installs the structural representation that connects pressure sensor in the welder head of the present invention
Fig. 2 is the operation principle block diagram of the pressure sensor of welder head of the present invention
Fig. 3 is the structural representation of a kind of concrete enforcement of welder head of the present invention
Among Fig. 1, the pressure sensor 3 that a band pressoreceptor 2 and deformation chamber 1 constitute is installed in welder head, the shape in deformation chamber generally is processed into as dumb-bell shape, pressoreceptor is installed in the lateral surface in deformation chamber, pressoreceptor has lead-out wire, and the lead-out wire of pressoreceptor also claims the pressure sensor lead-out wire.Pressure sensor is generally rectangular structure, and an end of cuboid pressure sensor is connected with the device that transmits weld force, and the other end is connected with welding head holder.As shown in Figure 1, at the two ends of the pressure sensor consistent with deformation chamber dumb-bell shape direction, wherein an end is connected with the device 4 that transmits weld force, the device that the transmits weld force setting pressure sensor use that can fix simultaneously.Weld force can be provided by manpower, mechanical force, compressed air power or electric power, can transmit manpower by pull bar so transmit the device of weld force, and screw mandrel transmits mechanical force, and pneumatic means transmits compressed air power or magnetic valve transmits electric power or the like.Pressure sensor and the method for attachment of transmitting the weld force device can be direct connections, sometimes in order to cushion, often adopt the method that connects indirectly.The other end that pressure sensor is connected with terminal clamp, its method of attachment can be direct connection equally, also can be indirect connections.Among Fig. 1,5 is pressure sensor and the welding head holder 6 indirect structures that are connected, and soldering tip 7 is installed on the welding head holder.
As shown in Figure 2, pressure sensor 3 is connected with pressoreceptor signal processing circuit 12 by the pressure sensor lead-out wire, and this signal processing circuit is connected with the interface of cpu circuit 11 again, the control circuit 13 in addition that is connected with cpu circuit, parameter display circuit 14 etc.During work, at first the button of needed weld force at control circuit presetted, and show at the parameter display circuit by CPU.When the device of weld force F15 by the transmission weld force, the tractive pressure sensor also drives welding head holder and soldering tip moves, make soldering tip and workpiece that certain contact force be arranged, this contact force is weld force just, the reaction force f16 of contact force and F acting in conjunction, make the deformation chamber produce deformation, the electrical potential difference that deformation produces, detected and be converted into electric signal by sensitive pressure sensor, by the pressure sensor signal processing circuit electric signal is amplified again, because pressure sensor signal processing circuit and control circuit, the parameter display circuit is all handled by CPU, when deformation power reaches default definite value, CPU sends triggering command, for soldering tip provides welding current.Because the electrical potential difference that the deformation of deformation chamber produces is very faint, is detected and be converted into electric signal by pressoreceptor, need to amplify by the pressure sensor signal processing circuit.So it is near that setting pressure sensor signal processing circuit tripping power sensor is wanted, and preferably is directly installed in the head framework, or is installed in the lateral surface of head framework, in order to avoid cause signal attenuation because of circuit is long, influences the control accuracy of weld force.
In the embodiment shown in fig. 3, with welder head framework 21 of metal processing, the method of setting pressure sensor is as follows in the head framework: an end of pressure sensor 3 is fixing by metal fixture block 22, and be connected with metal briquetting 23, this metal briquetting is connected with two little axles 24 on being fixed on framework, on two little axles the line sliding bearing is installed, this metal briquetting links with pull bar 25 again, and pull bar is connected with pedal by drag-line 26.The other end of pressure sensor is also fixing by metal fixture block 27, and is connected with slide-bar 28, and slide-bar two ends are equipped with the line sliding bearing and are fixed on the framework.The lower end of slide-bar is connected with welding head holder 6, and soldering tip 7 is installed on the welding head holder.During work, step on pedal with manpower, pedal is by drag-line tractive pull bar and metal briquetting, because little axle of two of fixing metal briquetting and slide-bar all are equipped with the line sliding bearing, the metal briquetting can very smooth-going area dynamic pressure sensor, slide-bar, welding head holder and soldering tip move down, make the soldering tip contact workpiece, the reaction force f of this contact force and traction force F make the deformation chamber deformation of pressure sensor, the electrical potential difference that deformation produces is detected and is converted into electric signal by pressoreceptor 2, be connected with the pressoreceptor signal processing circuit 12 that is installed in the framework madial wall by the pressure sensor lead-out wire, outer with the being installed in the head framework again circuit of pressure sensor signal processing circuit is connected.
The outer circuit of head framework comprises cpu circuit, control circuit, parameter display circuit etc.Cpu circuit has interface to be connected with the pressure sensor signal processing circuit, control circuit, the parameter display circuit in addition that are connected with CPU.Above-mentioned cpu circuit, control circuit, parameter display circuit etc. are made total control circuit, total control circuit is installed in the power controling box of welding machine, control cabinet face version is provided with the input button of control circuit and the display screen of parameter display circuit etc., is convenient to operation and observation.
