Description

Adjustable test fixture applied to bilateral display screen test Technical Field The utility model belongs to the technical field of screen testing, and particularly relates to an adjustable testing jig applied to testing of a bilateral display screen. Background Currently, there is no testing fixture available on the market for meeting the requirement of the dual-side crimping test of the display screen. In addition, the test fixture of display screen generally should single model when designing, just need to change the test fixture of corresponding size when changing the display screen of different models, therefore test cost is high, wait for test fixture to relate to the cycle length of processing. Disclosure of Invention The utility model aims to overcome the defects in the prior art, and provides an adjustable test fixture applied to testing of a double-sided display screen, so as to solve the problems that the double-sided crimping test requirement of the display screen and the design of the test fixture cannot cope with display screens of different types. In order to achieve the above purpose, the utility model is realized by adopting the following scheme: The utility model provides an adjustable test fixture applied to testing of a bilateral display screen, which comprises: A bottom plate; The test pressure heads are symmetrically arranged on two sides of the bottom plate, one side of the test pressure head is fixedly arranged on the bottom plate, and the other side of the test pressure head is movably arranged on the bottom plate according to the size of the display screen to be tested and is used for driving the flexible circuit board to be pressed down so as to be pressed down to press test points on two sides of the display screen to be tested for testing. Optionally, the test indenter comprises: A pressure head mounting seat; The pressure head is connected in the pressure head mounting seat in a sliding way. Optionally, the middle part of the pressure head is slidably connected in a chute formed in the pressure head mounting seat, and the two sides of the pressure head are fixedly connected with a first spring between the pressure head mounting seat. Optionally, the test indenter further comprises: the rotating support is fixedly connected in the pressure head mounting seat; A press connection handle, the middle part of which is rotationally connected with the rotary support, one end is abutted with the middle part of the pressure head, and the other end extends out of the pressure head mounting seat. Optionally, the test indenter further comprises: The second spring is fixedly connected between the pressure head mounting seat and the bottom of the crimping handle near the other end of the crimping handle. Optionally, a plurality of mounting holes are formed in a bottom plate of one side far away from the testing pressure head on one side and close to the testing pressure head on the other side, first connecting holes are formed in two sides of a pressure head mounting seat of the testing pressure head on the other side, and the testing pressure head on the other side is movably mounted on the bottom plate through the first connecting holes, the mounting holes and corresponding connecting pieces. Optionally, the method further comprises: The limiting block is provided with a first limiting column and a second connecting hole, and is movably arranged on a side bottom plate far away from the testing pressure head on one side and close to the testing pressure head on the other side through the second connecting hole, the mounting hole and the corresponding connecting piece; The second limiting columns are arranged on two sides of the pressure head mounting seat of the test pressure head on the other side; the limiting rod penetrates through and is fixedly connected with the first limiting column and the second limiting column.
