Description

Technical Field

[0001] The utility model belongs to the technical field of display screen production, and relates to a processing jig for screen function testing. Background Art

[0002] Display screens are I / O devices (input / output devices) for smart devices like mobile phones and computers. They transmit electronic files to the screen via specialized transmission equipment and then reflect them to the human eye. During the display screen production process, detecting defects such as dead pixels, bright pixels, and dark pixels is an essential step, impacting display quality and customer experience.

[0003] Moreover, at present, there are still certain technical problems in the function testing of display screens: in the current screen function testing structure, the display screen and the adapter module are on the same plane, and because the mainboard of the display screen is bent on its back, during testing, the screen FPC of the display screen needs to be turned 180 degrees and fastened to the adapter module and connected to the mainboard, so as to achieve the purpose of screen testing; and because the display screen and the adapter module are on the same plane, the screen FPC needs to be turned 180° before it can be connected to the adapter module. During the turning process, wrinkles may easily appear on the screen FPC, and the screen function test may be unstable and inconvenient for the operator to operate. Utility Model Content

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] The upper end of the test box is provided with a switching module connected to the test module;

[0007] A set of screen placement boards is provided on the front end face of the test box, which is provided with a test placement position for stably placing the display screen, and a test wiring slot is provided on the test placement position; the intersection angle between the placement plane of the test placement position in the screen placement board and the installation surface of the adapter module is less than 90°.

[0008] As a further solution of the present invention: a test box support base is provided at the lower end of the test box, and the test box support base is composed of a rotating base plate and a placement base plate provided at the lower end of the rotating base plate;

[0009] A set of universal turntables is provided on the placement base plate, and the rotating base plate is fixed to the upper end of the placement base plate through the universal turntables; a set of upwardly extending support frames are respectively provided at both ends of the rotating base plate, and a set of rotary damping shafts are provided between the support frames and the test box, and the connection between the support frames and the test box is realized through the rotary damping shafts.

[0010] As a further solution of the present invention: a plurality of limit blocks are provided in the screen placement plate, and the limit blocks are combined to form a test placement position for achieving stable placement of the display screen.

[0011] As a further solution of the present invention: a plurality of position-limiting mounting holes corresponding to common display screen sizes are provided in the screen placement plate, and the position-limiting blocks are installed in the position-limiting mounting holes by means of screw assemblies.

[0012] The beneficial effects of the present invention are as follows: by setting the intersection angle between the placement plane of the display screen test and the installation surface of the adapter module to be less than 90°, when the screen FPC of the display screen to be tested is connected to the adapter module, the screen FPC can be connected to the adapter module in a manner of bending less than 90°, thereby avoiding the occurrence of bending wrinkles on the screen FPC, improving the stability of the screen function test and facilitating the operator to perform corresponding test operations.

[0013] At the same time, during the test process, the tester can adjust the Y-axis and X-axis orientation of the display screen to be tested; this allows the tester to observe the display information on the display screen more conveniently and intuitively, effectively improving the convenience of the test work.
