[0031] Referring to Figure 1-2 An extrusion jig for a backplane of a liquid crystal display module proposed by the present utility model includes: a base 1, an extrusion tool 2 and a fixing tool 3; the extrusion tool 2 and the fixing tool 3 are both installed on the base 1; the fixing tool 3 includes: a first support component 31, a second support component 32 and a first adjustment component 33;

[0032] The first adjustment component 33 includes: a fixing block 331, a first movable block 332, a first adjustment screw 333 and a first base. The first base includes a first plate portion 334 fixed on the base 1 and a first seat portion 335 and a second seat portion 336 spaced apart and installed on the first plate portion 334. The first movable block 332 is slidably installed on the first plate portion 334 and is located between the first seat portion 335 and the second seat portion 336. The fixing block 331 is fixedly installed on the first plate portion 334 and is located between the first movable block 332 and the second seat portion 336. The first adjustment screw 333 sequentially passes through the first seat portion 335, the first movable block 332, the fixing block 331 and the second seat portion 336. The first adjustment screw 333 is rotatably connected to the first seat portion 335, the fixing block 331 and the second seat portion 336. The first support component 31 is fixed on the first movable block 332 and has a first card slot. The second support component 32 is fixed on the fixing block 331 and has a second card slot arranged opposite to the first card slot. The first movable block 332 has an internal thread adapted to the external thread of the first adjustment screw 333. Rotating the first adjustment screw 333 can drive the first movable block 332 to approach the fixing block 331 so that the first card slot approaches the second card slot and clamps the liquid crystal display module. Rotating the first adjustment screw 333 can also drive the first movable block 332 to move away from the fixing block 331 so that the first card slot and the second card slot are relatively far apart, and the liquid crystal display module is disengaged from the first card slot or the second card slot.

[0033] In the specific working process of this embodiment, when it is necessary to fixedly install the liquid crystal display module, first rotate the first adjusting screw 333 to drive the first movable block 332 away from the fixed block 331 so that the first clamping groove and the second clamping groove are relatively far away from each other. Then place the liquid crystal display module between the first clamping groove and the second clamping groove. Then rotate the first adjusting screw 333 to drive the first movable block 332 close to the fixed block 331 so that the first clamping groove approaches the second clamping groove and clamps the liquid crystal display module. When it is necessary to disassemble or replace the liquid crystal display module, first rotate the first adjusting screw 333 to drive the first movable block 332 away from the fixed block 331 so that the first clamping groove and the second clamping groove are relatively far away from each other, and make the liquid crystal display module disengage from the first clamping groove and / or the second clamping groove to disassemble the liquid crystal display module, and then install the next liquid crystal display module to be tested. The utility model can directly drive the first support assembly to move by rotating the first adjusting screw, which is convenient for installing / dismantling the liquid crystal display module.

[0034] In the existing method of fixing the liquid crystal display module, the support assembly cannot be closely attached to the liquid crystal display module, which will cause the liquid crystal display module to tilt, thus affecting the vertical relationship between the push-pull force gauge and the liquid crystal display module, and further affecting the accuracy of the test data of the backplane extrusion test of the liquid crystal display module. Therefore, ensuring the vertical relationship between the push-pull force gauge and the liquid crystal display module is the key to ensuring the accuracy of the test data of the backplane extrusion test of the liquid crystal display module.

The third gasket and the fourth gasket are both received in the second groove and are respectively disposed on both sides of the liquid crystal display module. A plurality of first fasteners 314 passing through the first support plate 311 fix one end of the liquid crystal display module in the first clamping groove formed by the first gasket 312 and the second gasket 313 by pressing the first gasket 312 and / or the second gasket 313, and a plurality of second fasteners passing through the second support plate fix the other end of the liquid crystal display module in the second clamping groove formed by the first gasket 312 and the second gasket 313 by pressing the third gasket and / or the fourth gasket.
