[0003] The backlight module is one of the important components of the touch screen. If there is no pressure holding process (i.e. pressurization), a gap will be generated between the automotive touch screen and the backlight module during bonding, resulting in low quality of the automotive touch screen and potential safety hazards. The existing pressure holding fixture can only hold pressure for one set of backlight module and TLI (Touch Panel and LCM Integration, Chinese name: touch screen and display integration, which is our common touch screen assembly) at a time, and the work efficiency is low.
[0004] Based on this, it is urgent to invent a pressure-maintaining fixture to solve the above-mentioned technical problems. Utility Model Content

[0009] The limiting assembly is used to limit the display screen; the plurality of pressure-maintaining blocks are pressed onto the corresponding display screens under the drive of the driving module.
[0010] In one specific embodiment, a working space is formed on the workbench, and the plurality of pressure-maintaining blocks reciprocate in the working space under the drive of the driving module.
[0011] Specifically, the pressure-maintaining module further comprises a connecting plate assembled on the driving module, and a plurality of pressure-maintaining blocks are detachably connected to the connecting plate;
[0012] The number of the pressure maintaining blocks is two.
[0013] In terms of size, the distance between the pressure maintaining blocks on both sides of the plurality of pressure maintaining blocks is not greater than the length of the connecting plate.
[0014] In terms of material, the buffer pad is made of silicone material.
[0015] In one specific embodiment, the limiting assembly includes a plurality of movable blocks and a plurality of limiting grooves located on the working plane of the workbench, and the plurality of limiting grooves form a cross structure;
[0016] The plurality of movable blocks are movably embedded in the corresponding limiting grooves through bolts and define the display screen.

[0026] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] In order to increase the sealing of the backlight module, firstly, glue dispensing treatment is implemented on the edge of the backlight module (the glue here adopts RTV glue, English name: Room Temperature Vulcanized Silicone Rubber, Chinese name: room temperature vulcanized silicone rubber, which is a one-component liquid material). The surface of RTV glue will automatically solidify within thirty minutes at room temperature. In order to prevent contamination of the RTV glue on the backlight module, the backlight module needs to be quickly assembled with TLI after being taken out after the glue dispensing treatment. In order to prevent the backlight module and TLI combination (that is, the display screen 15) from shrinking after the RTV glue cools down, it is necessary to use a pressure holding fixture 1 to hold the pressure.

The number of pressure-maintaining blocks 110 is two.
[0032] In one specific implementation manner, the distance between the pressure maintaining blocks 110 on two sides of the plurality of pressure maintaining blocks 110 is not greater than the length of the connecting plate 113 .
[0033] In one specific embodiment, a buffer pad 111 is attached to the bottom of the pressure maintaining block 110 , and the size and shape of the buffer pad 111 are compatible with the size and shape of the pressure maintaining block 110 .
[0034] In one specific embodiment, the material of the buffer pad 111 is silicone material.

[0036] The plurality of movable blocks 141 are movably embedded in the corresponding limiting grooves 140 through bolts and define the display screen.
[0037] In one specific embodiment, it also includes a switch key 13 and a control module 12 for controlling the holding pressure and the holding time.
[0038] In one embodiment, the workbench 10 includes a side plate 101 partially enclosed on the work plane of the workbench 10, and the drive module 112 is installed on the side plate 101 opposite to the work plane.
