All technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of this utility model. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not used to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0018] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Please refer to Figure 1 The present application provides an embodiment of a small LCD screen test fixture, which includes a test base plate 100, on which a product placement table 200 and a test probe mechanism 300 are fixed. The test probe mechanism 300 is fixed to one side of the product placement table 200, and a product fixing groove 210 is provided on the product placement table 200. The product fixing groove 210 is used to fix the small LCD screen to be tested. The test probe mechanism 300 has a probe 310, which is located above one side of the product fixing groove 210. During testing, the probe 310 is pressed downward onto the test connection point of the small LCD screen to be tested.

[0020] The test probe mechanism 300 of the present application is set on one side of the product placement table 200. During testing, the probe 310 is pressed against the top of the test connection point of the small LCD screen to be tested. When the LCD screen is tested, the small LCD screen to be tested is placed in the product fixing groove 210. The product fixing groove 210 is used to accommodate the product to be tested, which changes the connection position of the probe 310 and the connection point of the LCD screen to be tested. During testing, the probe 310 test mechanism is pressed downward. After the connection is completed, the power can be turned on to perform LCD screen detection. This can not only quickly complete the placement of the product to be tested, but also effectively prevent the displacement of the product to be tested during subsequent testing, thereby effectively shortening the test cycle, reducing test errors, and reducing the occurrence of product defects. Generally, the test cycle can be shortened from the original two minutes to thirty seconds.

[0021] like Figure 1 As shown, in this embodiment, the test probe mechanism 300 includes a lifting plate 320 and a plurality of positioning slides 330. One end of the positioning slide 330 is fixed to the test base plate 100, and the other end is connected to the lifting plate 320. The lifting plate 320 can slide up and down along the positioning slide 330. The probe 310 is arranged on the side of the lifting plate 320 above the product fixing groove 210. The positioning slide 330 realizes the precise positioning of the lifting plate 320 when it slides up and down, thereby ensuring the accuracy of the test. The lifting plate 320 that can slide up and down allows the distance between the product fixing groove 210 and the top of the probe 310 to be automatically controlled and adjusted, which not only facilitates the placement of the small LCD screen in the product fixing groove 210, but also prevents damage to the probe 310.

[0022] like Figure 1 As shown, in one embodiment, the test probe mechanism 300 further includes a support frame 340, which is fixed to the test base plate 100, and the top of the support frame 340 is located below the lifting plate 320. When the probe 310 is pressed down for testing, the lifting plate 320 first descends to a position where its bottom end is pressed against the top of the support frame 340. The support frame 340 provides stable support for the lifting plate 320, so that the lifting plate 320 can be stably supported in a fixed position, simplifying the structure of the test probe mechanism 300 and reducing the energy consumption of the lifting plate 320. At the same time, the support frame 340 also limits the descending height of the lifting plate 320, preventing damage to the probe 310 caused by excessive downward pressure when the lifting power source pulling the lifting plate 320 fails, thereby protecting the test probe mechanism 300. This helps to extend the service life of the fixture.

[0023] In one embodiment, the support frame 340 is fixedly connected to the test base plate 100 by screws. The product placement platform 200 is also fixedly connected to the test base plate 100 by screws. This screw connection simplifies the fixing method and facilitates the assembly and production of the small LCD test fixture, thereby effectively reducing the production cost of the small LCD test fixture. It also facilitates the replacement of individual components in the event of a fault.

[0024] like Figure 1 As shown, in one embodiment, a screen switch button 110 and a power switch button 120 are further included. The screen switch button 110 and the power switch button 120 are arranged at the edge of the test base plate 100. There are two screen switch buttons 110, namely screen switch up and screen switch down. The screen switch up button, screen switch down button and the power switch button 120 are arranged in a row and located on the same straight line. In addition, the various control buttons are arranged at the edge of the test base plate 100 to facilitate the tester's key operation. Each button is away from the product placement table 200 and the test probe mechanism 300, which can effectively prevent the tester from accidentally touching the product to be tested or the probe 310 when operating the buttons, thereby ensuring the accuracy of the test.

[0025] like Figure 1 As shown, in one embodiment, on the product placement table 200, access slots 220 are provided on both sides of the product fixing slot 210. The depth of the access slots 220 is greater than the depth of the product fixing slot 210. The access slots 220 on both sides of the product fixing slot 210 provide gripping space for taking the small LCD screen out of the product fixing slot 210, facilitating the placement and removal of the small LCD screen from the product fixing slot 210 before and after testing, effectively reducing the time required to take the small LCD screen out, thereby effectively shortening the test cycle time.
