Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0027] Please refer to the following: Figures 1 to 3 This utility model discloses a multi-point synchronous testing device for screen components, comprising: a frame 1, a limiting fixture 2, a multi-point test probe structure 3, a test reciprocating structure 4, a drive mechanism 5, and a control module 6; the limiting fixture 2 is disposed on the frame 1, the multi-point test probe structure 3 is disposed adjacent to the limiting fixture 2, the test reciprocating structure 4 is movably disposed within the frame 1, and the multi-point test probe structure 3 is connected to the test reciprocating structure 4; the drive mechanism 5 is disposed on the frame 1, and the drive mechanism 5 is drively connected to the test reciprocating structure 4; the control module 6 is disposed on the side of the frame 1, and the control module 6 is controllably connected to the drive mechanism 5.

[0028] Specifically, when the screen element multi-point synchronous testing device of this utility model is in operation, the external screen element to be tested is placed in the limiting fixture 2, and the limiting fixture 2 limits the connection of the screen element. Afterwards, the user can input control commands into the control module 6 to activate the drive mechanism 5, causing the drive mechanism 5 to drive the test reciprocating structure 4 according to preset programming steps. This allows the multi-point test probe structure 3 connected to the test reciprocating structure 4 to simultaneously test multiple contacts of the screen element, and enables external testing equipment pre-connected to the multi-point test probe structure 3 to determine the pass / fail status of the screen element. Therefore, the screen element multi-point synchronous testing device of this utility model reveals a compact and easy-to-deploy screen multi-point testing device, which improves the ease of use of screen testing fixtures.

[0029] Furthermore, the limiting fixture 2 includes a fixture base 201, a placement cavity 202, a pick-and-place section 203, and limiting sections 204.

The pick-and-place section 203 is disposed on the side of the placement cavity 202, and several limiting sections 204 are evenly distributed around the periphery of the placement cavity 202. Specifically, the external screen element to be tested can be placed into the placement cavity 202. The pick-and-place section 203 facilitates the placement of the screen element by the operator's hand. The limiting sections 204 are used to connect to preset protruding positions on the screen element to prevent displacement of the screen element during testing.

[0030] Furthermore, the multi-point test probe structure 3 includes a test moving base 301 and a plurality of test probes 302; the test moving base 301 is movably disposed above the frame 1, and the plurality of test probes 302 are distributed within the test moving base 301. Specifically, each test probe 302 is electrically connected to an external test device, thereby allowing the test moving base 301 to be close to the limiting fixture 2, and each test probe 302 can correspond to a point on the test screen element.

[0031] Furthermore, the test reciprocating structure 4 has a limiting support 401, a guide connecting post 402, and a sliding connecting sleeve 403; a plurality of the limiting support 401 are distributed and connected to the frame 1, a guide connecting post 402 is connected between every two limiting support 401, a sliding connecting sleeve 403 is movably sleeved on each guide connecting post 402, and each sliding connecting sleeve 403 is connected to the test moving seat 301.

[0032] Furthermore, the drive mechanism 5 includes a connecting rod 501, a drive connecting block 502, a telescopic rod 503, and a drive cylinder 504; the connecting rod 501 connects the test moving seat 301 and the drive connecting block 502 respectively, the drive connecting block 502 is connected to the telescopic rod 503, the drive cylinder 504 is drivenly connected to the telescopic rod 503, the drive cylinder 504 is connected to the frame 1, and the control module 6 is controlledly connected to the drive cylinder 504.

[0033] Specifically, the control module 6 includes necessary electrical components and control buttons, such as a power switch, reset button, automatic button, feed button, and rewind button. The user can operate the control module 6 to activate the drive cylinder 504, which in turn drives the telescopic rod 503 to extend or retract, thereby driving the drive connecting block 502 to reciprocate. The drive connecting block 502, through the connecting rod 501, can then drive the test moving seat 301 to reciprocate. The sliding connecting sleeve 403, connected to the test moving seat 301, can slide along the guide connecting post 402 as the test moving seat 301 moves, making the movement of the test moving seat 301 smoother.

[0034] Furthermore, the drive connecting block 502 includes an L-shaped connecting block 502a and a sliding connecting seat 502b; the L-shaped connecting block 502a connects the telescopic rod 503 and the connecting rod 501 respectively; the sliding connecting seat 502b is connected to the bottom of the L-shaped connecting block 502a and is movably connected to the frame 1. Specifically, the sliding connecting seat 502b makes the L-shaped connecting block 502a more stable when it reciprocates.

The limiting fixture 2 is mounted on the frame 1, and the multi-point test probe structure 3 is positioned adjacent to the limiting fixture 2. The test reciprocating structure 4 is movably disposed within the frame 1, and the multi-point test probe structure 3 is connected to the test reciprocating structure 4. The drive mechanism 5 is mounted on the frame 1 and is drively connected to the test reciprocating structure 4.
