A kind of gasbag-type joint tool
Technical field
The utility model relates to a kind of tool that is applied to automated production equipment, more particularly, relates to a kind of gasbag-type joint tool.
Background technology
Touch-screen (touch screen) is called again " touch screen ", " contact panel ", it is a kind of induction type liquid crystal indicator that receives the input signals such as contact, as a kind of up-to-date computer input apparatus, it is simple, convenient, the most natural present a kind of man-machine interaction mode.The touch-screen of main flow such as resistive touch screen are to adopt film to add the structure of upper glass basically at present, so, in the production of touch-screen, (comprise TP FILM SENSOR etc. soft to hard to hard soft to the soft applying) technique of fitting belongs to one of most important technique, and the efficient of applying link and quality will directly affect efficient and the production cost of whole touch-screen production procedure.
The applying step is mainly completed on make-up machine, will process through early stage the plate of (destatic, de-bubble, subsides optical cement) or film and carry out machinery locate and fit on make-up machine.It is generally to adopt vertical pressurized, heated to fit that machinery is fitted, and heats after namely adopting pressure head to treat the element mechanical compression of applying, to reach the purpose of applying.In the prior art, pressure head adopts silica gel injection moulding pressure head mostly, adopts silica gel injection moulding pressure head shortcoming to be:
In the process of fitting product edge because the silica gel pressure head is smooth, the impact such as mismachining tolerance during smooth and injection moulding, the pressure of the pressure that it is subject to and silica gel pressure head mid portion does not wait, especially when production large scale touch-screen, because the size of element own is larger, its edge and place, centre discontinuity tend to cause producing a large amount of bubbles, even this bubble also is difficult to elimination after carrying out the de-bubble processing, thereby have a strong impact on the quality of product;
2. the size of silica gel die head is fixed, its size designs according to element to be fitted, but in actual production, component size to be fitted is not of uniform size, and this just needs to prepare a plurality of silica gel pressure heads, increased cost, in the time need to changing wait the element of fitting, also need to change the silica gel pressure head of corresponding size simultaneously, this needs again to spend man-hour, reduce production efficiency, increased labour cost.
The utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art part, a kind of gasbag-type joint tool that uniform pressure can be provided and can adapt to the element of sizes is provided, this tool possesses simple in structure simultaneously, is easy to process and advantage with low cost.
Above-mentioned technical problem can be realized by following technological means: a kind of gasbag-type joint tool, comprise air bag, offer seal cover board and the seal frame of cover plate air admission hole, wherein seal frame is arranged on below seal cover board, and adopt with seal cover board and be tightly connected, described air bag between seal frame and seal cover board and its periphery be fixedly clamped by described seal frame and seal cover board, the below of described air bag, surround and form airtight vacuum cavity by the periphery of seal frame.The element that the size of described seal cover board and seal frame and profile can be processed is according to actual needs made size and the external form that needs.Use in use charger by the cover plate air admission hole on seal cover board, air bag to be inflated air bag is expanded, the gas pressure of inside air bag acts on element to be processed as laminate pressure.
Further, described gasbag-type joint tool also includes the air inlet piece of hollow strip, and the top of air inlet piece has air inlet connecting hole, the lower opening of air inlet piece, described air inlet piece is fixedly mounted on described seal cover board, and its lower opening is corresponding with described cover plate air admission hole.This being designed with is beneficial to expansion air inlet area, the gas shock power that makes air bag be subject to is comparatively all even soft, thereby make the expansion of air bag more average, the pressure that is transmitted on element to be processed is more even, even the marginal portion also can be subject to uniform pressure, can further guarantee the effect of fitting, improve yields.
Further, described cover plate air admission hole is no less than two, evenly distributes in the area that the lower opening of described air inlet piece covers.In actual applications, described cover plate air admission hole can be designed as equally distributed a plurality of aperture, thereby the air-flow that further guarantees the inflow air bag is more even.
Further, described air bag adopts silica gel to make.The silica gel material has spreading rate preferably, and flexible smooth, can protect to greatest extent components and parts to be processed, reduces spoilage, improves yields.
Usefulness of the present utility model is:
1. laminate pressure is the expansion generation by air bag, so size evenly, makes element to be fitted stressed evenly, reduce the generation of bubble, greatly improve yields, reduced processing cost, reduce manual sorting's number of times, can effectively improve automated production efficient;
2. by adjusting the aeration quantity of air bag, can adjust the size of air bag, change the expansion area of air bag, to adapt to the element of different size and shape, not need to prepare a plurality of pressure heads, more not need the artificial frequent pressure head of changing, reduce artificial use;
3. the seal frame itself that is positioned at seal cover board below possesses certain thickness, and seal frame itself surrounds the formation vacuum cavity, does not need to arrange in addition baffle plate again and consists of vacuum cavity, simple in structure, easily process, reduced the number of spare parts of equipment, reduced the cost of equipment itself.

The specific embodiment
Gasbag-type joint tool as shown in Figures 1 and 2 comprises air inlet piece 1, offers the seal cover board 2 of cover plate air admission hole 21, air bag 3 and the seal frame 4 of silica gel material.Wherein air inlet piece 1 is the hollow strip, its top has air inlet connecting hole 11 and lower opening, and air inlet piece 1 is fixedly mounted on seal cover board 2, and its lower opening is corresponding with cover plate air admission hole 21, cover plate air admission hole 21 is a plurality of, evenly distributes in the area that the lower opening of air inlet piece 1 covers.
Seal frame 4 is arranged on seal cover board 2 belows, and adopts with seal cover board 2 and be tightly connected, and air bag 3 is between seal frame 4 and seal cover board 3, and the periphery of air bag 3 is fixedly clamped 3 by seal frame 4 and seal cover board.The below of air bag 3, surround and form an airtight vacuum cavity 5 by the periphery of seal frame 4.In this specific embodiment, seal cover board 2 and seal frame 4 are rectangle, and in actual applications, the element that seal cover board 3 and seal frame 4 can be processed is according to actual needs made size and the external form that needs.Use in use charger by air inlet piece 1 inflation, gas enters air bag 3 by 21 pairs of the cover plate air admission holes on seal cover board 2 expands air bag 3, and the gas pressure of air bag 3 inside acts on element to be processed as laminate pressure.This laminate pressure is the expansion generation by air bag, so size evenly, makes element to be fitted stressed evenly, reduce the generation of bubble, greatly improve yields, reduced processing cost, reduce manual sorting's number of times, can effectively improve automated production efficient.When needs are processed the element of different size, adjust the aeration quantity of air bag, just can change the expansion area of air bag, to adapt to the element of different size and shape, do not need to prepare a plurality of pressure heads, more do not need the artificial frequent pressure head of changing, reduced artificial use.
Above embodiment is for understanding the utility model; be not to be to restriction of the present utility model; the those of ordinary skill in relevant field; on the basis of the described technical scheme of claim; can also make multiple variation or modification, these variations or modification should be understood to still belong to protection domain of the present utility model.
