[0054] A lifting motor 1, a first plate 2, a second plate 3, a third plate 4, a fourth plate 5, and a pressure wheel assembly 6;

[0057] The lifting motor 1 is used to drive the threaded rod to rotate forward and backward.

[0058] Both the third plate 4 and the fourth plate 5 are arc-shaped and have the same radius.

[0059] First lifting plates 8 and second lifting plates 9 are respectively provided on both sides of the second plate 3;

[0060] The first lifting plate 8 is slidably installed on a first slide rail 10, and the first slide rail 10 is installed on a first side plate 11;

[0061] The second lifting plate 9 is slidably installed on a second slide rail 12, and the second slide rail 12 is installed on a second side plate 13;

[0062] Both the first side plate 11 and the second side plate 13 are installed on the first plate 2, and the first slide rail 10 and the second slide rail 12 are arranged in the up and down direction.

[0063] The pressure wheel assembly 6 includes:

[0064] An upper fixing block 601, a lower fixing block 602, an upper guide rod 603, a lower guide rod 604, a conductive rod 605, and a pressure wheel 606;

[0065] A number of through holes are provided on the third plate 4 and the fourth plate 5;

[0066] One end of the upper guide rod 603 is installed on the upper fixing block 601 and the other end is inserted into the through hole;

[0073] A handle 16 is further provided on the first plate 2 to facilitate the movement of the entire mechanism.

[0074] The principle of the present utility model is as follows:

[0075] Lifting motor 1 and screw system: The lifting motor 1 is installed on the second plate 3, and its rotating shaft is equipped with a threaded rod. A threaded block 7 matching it is installed on the first plate 2. When the lifting motor 1 is started, it drives the threaded rod to rotate forward or backward. Since a threaded connection is formed between the threaded rod and the threaded block 7, during the rotation of the threaded rod, a relative displacement will occur with the threaded block 7, causing the lifting motor 1 and the second plate 3 fixed thereto to move along the axis direction of the threaded rod (i.e., the up and down direction).

[0076] Height adjustment of the pressing wheel assembly 6: The third plate 4 and the fourth plate 5 are respectively fixed on both sides of the second plate 3, and a plurality of pressing wheel assemblies 6 are installed on these two plates. When the second plate 3 moves up and down with the lifting motor 1, the third plate 4 and the fourth plate 5 move synchronously therewith, thereby driving the pressing wheel assemblies 6 installed thereon to move up and down, realizing the automatic adjustment of the test height of the pressing wheel 606.

[0077] The structure of the pressing wheel assembly 6 ensures its stability and accuracy during movement:

[0078] Guide rod and spring 607 system: Each pressure wheel assembly 6 is composed of an upper fixing block 601, a lower fixing block 602, an upper guide rod 603, a lower guide rod 604, a conductive rod 605 and a pressure wheel 606. The upper guide rod 603 and the lower guide rod 604 are respectively fixed on the upper fixing block 601 and the lower fixing block 602, and pass through the through holes on the third plate 4 or the fourth plate 5 to play a guiding role. The spring 607 below the lower fixing block 602 provides stable support and buffering for the pressure wheel 606, ensuring that the pressure wheel 606 can maintain a consistent pressure when contacting electronic components of different thicknesses.

[0079] Adjustability and interchangeability: The third plate 4 and the fourth plate 5 are detachably mounted on the second plate 3 through the fixing rod 14, allowing users to easily adjust or replace the pressure wheel assembly 6 as needed. In addition, the locking rod 15 on the second plate 3 can be locked or released on the first plate 2 to ensure the stability of the mechanism in the non-adjusted state.

[0080] In summary, through the ingenious mechanical design and precise transmission mechanism of the present utility model, the automatic adjustment of the test height of the pressure wheel 606 is realized, which greatly facilitates the specification replacement during the detection process of chip electronic components and improves the detection efficiency and accuracy.

[0081] The above are only the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or direct / indirect application in other related technical fields, is included in the protection scope of the present utility model.
