Detailed Implementation

[0016] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a test cabinet 1, a drawer module 2, a pressing module 3, and a test module 4. The drawer module 2 is disposed on one side of the test cabinet 1 and slides inside the test cabinet 1. The test module 4 includes a carrier module 5 and a pressure plate module 6. The carrier module 5 is disposed at the support end of the drawer module 2. Two sets of pressing modules 3 are respectively disposed on both sides of the pressing position inside the test cabinet 1 and drive the pressure plate module 6 to cooperate with the flexible flat cable product 7 on the upper end of the carrier module 5. Therefore, the drawer module 2 can realize the push-pull loading and unloading of the carrier module 5, and the pressing module 3 drives the pressure plate module 6 to achieve pressing and testing of several sets of flexible flat cable products 7. The structure is simple and highly automated.

[0017] like Figure 2 and Figure 3 As shown, in this embodiment, the carrier module 5 includes a base plate 51, a lower floating plate 52, and a product carrier 53. The lower floating plate 52 is floatingly connected to the upper surface of the base plate 51, and the product carrier 53 is disposed on the upper surface of the lower floating plate 52. The flexible flat cable product 7 cooperates with the contouring structure on the product carrier 53. Therefore, the floating cooperation between the lower floating plate 52 and the base plate 51 provides a buffering effect during the pressing process, preventing the die from over-pressing the flexible flat cable product 7 and causing damage.

[0018] like Figure 3 and Figure 4 As shown, in this embodiment, the pressure plate module 6 includes an upper pressure plate 61 and an upper floating plate 62. The upper floating plate 62 is floatingly connected to the lower end face of the upper pressure plate 61. The two sides of the upper end face of the upper pressure plate 61 are connected to the corresponding movable ends of the lower pressure module 3. The upper pressure plate 61 drives a plurality of concave and convex needle molds 63 on the lower end face of the upper floating plate 62 to cooperate with the product carrier 53. It can be seen that the upper floating plate 62 and the lower floating plate 52 can achieve bidirectional floating during pressing. The concave and convex needle molds 63 are positioned using the shape of the ZIF flexible flat cable, and their positioning depth is 0.5mm, which can overcome the stress of the flexible flat cable and prevent it from jumping out of the needle mold positioning cavity before testing and causing pressure damage.

[0019] like Figure 3 and Figure 5As shown in the embodiment, the product carrier 53 comprises a carrier bottom plate 531, a small carrier plate 532 arranged on the upper end face of the carrier bottom plate 531, a plurality of product profiling grooves 534 arranged on the upper end face of the small carrier plate 532, and a carrier plate outer frame 533 connected with the upper end face of the carrier bottom plate 531 and provided with a relief groove 535 through which the pressing plate structure on the lower end face of the upper floating plate 62 is matched with the soft flat cable product 7 on the product profiling groove 534. Thus, the plurality of product profiling grooves 534 can simultaneously fix a plurality of products, and the carrier plate outer frame 533 makes the product carrier 53 more evenly stressed during the pressing process.

[0020] As shown in the embodiment, the lower floating plate 52 is provided with a plurality of sensors 8 matched with the soft flat cable product 7 on the product profiling groove 534. Figure 3

[0021] As shown in the embodiment, the lower end face of the upper floating plate 62 is provided with a positioning pin 9, and the upper end face of the lower floating plate 52 is provided with a positioning hole 10 matched with the positioning pin 9. Figure 3

[0022] As shown in the embodiment, the upper pressing plate 61 is provided with a code scanning gun module 11 matched with the identification code on the product carrier 53 through the upper floating plate 62. Figure 3

[0023] As shown in the embodiment, one side of the bottom plate 51 is provided with a collision prevention block 12. Figure 1

[0024] As shown in the embodiment, the upper pressing plate 61 is provided with a code scanning gun module 11 matched with the identification code on the product carrier 53 through the upper floating plate 62. Figure 6 Figure 1 ​​​​​As shown, in this embodiment, the pressing module 3 includes a pressing cylinder 31 and a pressing plate 32. Two sets of pressing cylinders 31 are respectively disposed on both sides of the pressing position inside the test cabinet 1. The pressing plate 32 is connected to the movable end of the pressing cylinder 31 and is connected to the upper end of the upper pressing plate 61. The pressing cylinder 31 drives the upper floating plate 62 to cooperate with the product carrier 53. Therefore, the pressing cylinder 31 drives the upper floating plate 62 to press and connect with the product carrier 53, realizing the contact and electrical connection test between the needle mold and the product.

[0025] like ​ As shown in the figure, in this embodiment, the test cabinet 1 is equipped with a heat dissipation module 13. Therefore, the heat dissipation module 13 can dissipate the heat generated during testing, preventing excessive heat buildup and its impact on the test results.

[0026] The working principle of this invention is as follows: Before the equipment is started, the drawer module 2 is pushed out, and a person or a robot puts the full product carrier 53 onto the lower floating plate 52. Several sensors 8 identify the presence or absence of products on the product contouring groove 534. After the detection is completed, the drawer module 2 is pushed in, and the carrier module 5 enters the pressing detection position. The pressing cylinder 31 drives the upper floating plate 62 to press down and position and contact the lower floating plate 52. The pressing continues to press the concave and convex needle mold 63 to contact and press and fix the upper surface of the flexible flat cable product 7. Several flexible flat cable products 7 are tested by power-on. After the test is completed, each component is reset, the drawer module 2 is pushed out, and several flexible flat cable products 7 to be tested are replaced. The above steps are repeated to realize the automated, multi-cavity, and multi-flexible buffer synchronous testing of multiple sets of flexible flat cable products.

[0027] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
