[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0026] Reference Figure 1-2 , this embodiment provides a multi-product serial testing mechanism.

[0027] Specifically, the multi-product serial testing mechanism includes a testing mechanism 100 .

[0028] The testing mechanism 100 includes a frame 101, the upper outer wall of the frame 101 is equipped with a pressing cylinder 102, and the output end of the pressing cylinder 102 is equipped with a pressing plate 103, and a test fixture 104 is placed under the pressing plate 103, and a lower test module 105 is arranged at the lower part of the test fixture 104, and test modules 106 are placed on both sides of the test fixture 104, and a transverse cylinder 107 for driving its movement is installed on the outer side of the test module 106.

[0029] Furthermore, a plurality of placement positions are provided on the surface of the test fixture 104. By providing a plurality of placement positions on the surface of the test fixture 104, the need for simultaneous series testing of multiple products can be met, thereby improving efficiency and saving labor costs.

[0030] During specific testing, a belt line is used to allow the fixture to automatically flow to the test module position for automatic testing. During testing, the cup head probe and the high current probe on the lower test module 105 and the test module 106 are respectively in contact with the pins on the outside of the product, and the high voltage probes of the copper guide blocks on both sides are pressed onto the product. The current flows into the product pins through the copper guide blocks on both sides to achieve the series connection between the two. The products are connected in pairs through the structure for series testing. After the instrument detection and action are completed, a heat dissipation groove is added to the copper guide block for heat dissipation. Through the coordinated setting between the test module 106 and the test fixture 104, multiple products can be connected in series with the test module 106 at the same time, which greatly improves the production efficiency and saves a lot of labor costs. Example 2

[0031] Reference Figure 1-5 , which is the second embodiment of the utility model, is based on the previous embodiment, and is different from the previous embodiment in that:

[0032] The testing mechanism 100 further includes a limiting member 108 located on a side wall of the frame 101 and a positioning member 109 located inside the testing fixture 104 .

[0033] Specifically, the limiting member 108 includes a push rod 108a fixed on the side wall of the frame 101, and the output end of the push rod 108a is fixed to a connecting frame 108b through a coupling, and a top column 108c is provided on the outer side of the connecting member 108bD.

[0034] A placement cavity 104 a is provided inside the test fixture 104 , and a round hole that can cooperate with the top column 108 c is provided on the outside of the test fixture 104 .

[0035] The positioning member 109 includes a movable plate 109a movably arranged inside the placement cavity 104a, a spring 109b is arranged on the outer side of the movable plate 109a, a plurality of guide grooves 109c are left on the surface of the movable plate 109a, guide columns 109d are arranged inside the guide grooves 109c, a clamping plate 109e is arranged on the top of the guide column 109d, the guide column 109d and the clamping plate 109e are integrally arranged, and a positioning column 109f is also integrally arranged on the outer wall of the clamping plate 109e.

[0036] Furthermore, the guide groove 109c is inclined gradually outward along the inward direction of the movable plate 109a, and the guide groove 109c and the guide column 109d are slidably matched. When the movable plate 109a gradually moves toward the inside of the test fixture 104 under the push of external force, the guide column 109d will gradually approach the axial direction of the test fixture 104 under the thrust of the guide groove 109c, and then the positioning column 109f can gradually extend out and contact with the outer wall of the product, thereby achieving positioning and clamping of the product, avoiding shaking and shifting of the product during the test process, resulting in poor contact between the pin and the probe, and ensuring the smooth and efficient implementation of the series test.

[0037] At the same time, two groups of guide grooves 109c are symmetrically arranged about the axis of the movable plate 109a, and each group is provided with 8. The interior of the guide grooves 109c is equipped with guide pillars 109d. The coordinated array arrangement between the multiple guide grooves 109c and the guide pillars 109d can achieve the purpose of synchronously positioning multiple products, further improve the positioning and detection efficiency of the products, and meet the user's usage needs.

[0038] During use, before the test fixture 104 gradually moves to the predetermined position, the push rod 108a drives the connecting frame 108b and the top column 108c to move downward, so that the top column 108c moves to the same plane as the outer circular hole of the placement cavity 104a. At this time, as the test fixture 104 continues to move, the top column 108c enters into the interior of the test fixture 104 and through the interaction force between it and the moving plate 109a, the moving plate 109a squeezes the spring 109b to move inward, and then the clamping plate 109e drives the positioning column 109f to extend under the guidance of the guide groove 109c to position the product, so as to ensure the stability of the product during the detection process and avoid poor contact between the product and the test module 106 and affect the detection accuracy.
