Correspondingly, the second magnetic member 600 is bonded to the top surface or side wall surface of the base assembly 100, and the number and fixed position of the second magnetic member 600 are set corresponding to the first magnetic member 500, so that the first magnetic member 500 is magnetically connected to the second magnetic member 600, and then the adapter plate 400 is fixed to the base assembly 100 by magnetic attraction. In the specific implementation process, the adapter plate 400 is magnetically connected to the side wall of the base assembly 100 to avoid occupying the top surface space of the base assembly 100, so that the top surface space of the base assembly 100 is used to set the support seat 200 and place the display screen, and more display screens can be placed.

In this way, through the magnetic attraction of the first magnetic component 500 and the second magnetic component 600, the adapter plate 400 is fixed on the base assembly 100, and when replacing the display screen to be tested, the adapter plate 400 is moved away from the base assembly 100 to release the magnetic attraction, and then the corresponding adapter plate 400 is adsorbed on the base assembly 100, which is convenient for replacing the adapter plate 400. In addition, the second magnetic attraction component 600 may be a magnetic attraction region provided on the adapter plate 400 , the magnetic attraction region having a magnetic attraction coating formed by a magnetic attraction material, and magnetically cooperates with the first magnetic attraction component 500 .

[0050] Optionally, the adapter board 400 is provided with an adapter interface 410 and a socket 420, and the socket 420 is electrically connected to the adapter interface 410.

Specifically, the FPC board of the display screen is connected to the socket 420 through a cable, so that the test board 300 can realize signal transfer through the adapter board 400, thereby controlling the display screen.

[0052] Furthermore, a plurality of sockets 420 are provided on the adapter board 400, and each socket 420 corresponds to a display screen. Thus, the adapter board 400 can be electrically connected to a plurality of display screens at the same time, so that the test board 300 can be electrically connected to a plurality of display screens through centralized wiring, thereby increasing the number of display screens controlled by the test board 300 for testing each time and improving the single test quantity.

[0053] In a specific implementation process, a power interface 113 is provided at the edge of the base assembly 100 , the test board 300 is connected to the power interface 113 , and the power interface 113 is also connected to an external power source for powering the test board 300 .

[0054] Optionally, the base assembly 100 includes a body 110, a top cover 120 and / or a rotating member 130. The body 110 and the top cover 120 surround and form a cavity, and the top cover 120 and the body 110 are rotatably connected through the rotating member 130. In a specific implementation process, the rotating member 130 may be a rotating shaft, and the top cover 120 may be rotatably connected to the body 110 through the rotating shaft. In this embodiment, refer to Figure 3 and Figure 4 As shown, the rotating member 130 is a hinge, and the top cover 120 and the body 110 are rotatably connected by the hinge, so that the cavity can be opened by flipping the top cover 120 to take and place the test board 300, which is convenient for replacing the test board 300. Further, the body 110 is provided with a notch 114 at the edge close to the top cover 120. Specifically, the notch 114 extends out of the edge of the body 110, and the bottom edge of the top cover 120 can be contacted through the notch 114, so that the top cover 120 can be opened conveniently.

[0055] Optionally, the support seat 200 includes a support portion 210 and a limiting portion 220 , wherein the limiting portion 220 is disposed on the support portion 210 and is spaced apart along an extending direction of the support portion 210 , and a spacing space between two adjacent limiting portions 220 forms a placement groove 230 .

[0056] The support part 210 is fixed on the top surface of the base assembly 100, that is, the support part 210 is connected to the top cover 120. In the specific implementation process, the surface of the support part 210 away from the top cover 120 is connected to the limiting part 220, and the limiting part 220 plays a role in limiting the display screen.

[0058] On the one hand, the side wall of the display screen is supported on the support part 210. If the display screen is in a nearly vertical state in the placement groove 230, the side wall of the display screen needs to bear the overall gravity and is prone to bending; on the other hand, one side of the display screen is the back plate and the other side is the display surface. If the display surface contacts the limiting part 220, it may cause indentation, affecting the display effect and causing product defects. However, this embodiment sets an inclined support groove so that the display screen is tilted in the support groove, and the back plate of the display panel contacts the limiting part 220, thereby avoiding damage to the display surface and ensuring the yield of the product; on the other hand, in practice, when the display screen is aging tested, the test fixture is placed on the shelf, and the shelf is arranged in multiple layers. When the display screen is placed vertically in the placement groove 230, the user needs to bend down to observe when observing the display screen at the bottom of the shelf, which is very inconvenient. When the display screen is placed in the placement groove 230 at an angle, the user can stand and observe the display screen at the bottom of the shelf, thereby reducing the user's work intensity.

[0059] Optionally, the base assembly 100 is also provided with an auxiliary seat 700, which is arranged between two adjacent support seats 200.

[0060] In the specific implementation process, the setting of the auxiliary seat 700 refers to the above-mentioned support seat 200, and will not be described in detail here. However, it should be noted that the auxiliary seat 700 is provided with an auxiliary limiting part with reference to the support seat 200, and an auxiliary groove 710 is formed between the two auxiliary limiting parts. The auxiliary groove 710 cooperates with the placement groove 230 to place the display screen, wherein the extension length of the auxiliary limiting part is less than the extension length of the limiting part 220 in the support seat 200 to adapt to a smaller display screen, thereby meeting the needs of 8-17 inch display screens. In addition, when placing a small-sized display screen, the auxiliary limiting part effectively avoids the user's hands, making it easy to take and place the display screen.

[0061] Optionally, the support portion 210 is flexibly arranged. In one embodiment, the support portion 210 is made of rubber or silicone. The support portion 210 made of soft material can prevent the display screen from being damaged by collision. In the specific implementation process, the hardness of the rubber or silicone is 30° to protect the display screen. In another embodiment, the outer peripheral surface of the support portion 210 is wrapped with a protective layer, wherein the material of the protective layer is a soft material such as rubber or silicone, and of course, it can also be felt, etc., to protect the display screen from collision damage.

[0062] Optionally, the support seat 200 is connected with a connector 800, and the connector 800 is locked and connected to the base assembly 100. In the specific implementation process, the connector 800 is a screw, one end of which passes through the support portion 210 of the support seat 200 and is locked on the top cover 120 of the base assembly 100 to fix the support seat 200. Of course, when the support seat 200 is damaged, the screw can be removed and replaced to extend the service life of the test fixture.
