It can be seen that after the lifting cylinder 21 drives the lifting plate 22 to lift the test fixture 6 into place, the pressing assembly 4 presses the interface end of the product 7 on the test fixture 6 to prevent the test fixture from falling off during the closing and testing process. The first push rod module 31 and the second push rod module 32 respectively press and fix the two ends of the product 7 to perform product testing.
[0017] like Figure 3 As shown, in this embodiment, the test fixture 6 is provided with a product profiling groove 8, the product 7 is limitedly matched with the product profiling groove 8, a first push block 9 and a first oblique push block 10 are provided on one side of the product profiling groove 8, and a second push block 11 is provided on the other side of the product profiling groove 8, and the first push block 9, the first oblique push block 10 and the second push block 11 are slidably matched with the sliding groove structure on the upper end surface of the test fixture 6.

[0018] like Figure 3 As shown, in this embodiment, the first push block 9 and the second push block 11 are respectively matched with the pressing ends of the two ends of the product 7 in the product profiling groove 8, and the pressing end of the first oblique push block 10 is matched with the upper end surface of the test fixture 6. It can be seen that the first push block 9 and the second push block 11 are respectively pressed with the two ends of the product 7, and the first oblique push block 10 can be pressed with the test fixture 6 to ensure the stability of the overall detection.
[0019] like Figure 1 and Figure 7As shown, in this embodiment, the pressing assembly 4 includes a pressing bracket 41, a first side-pushing cylinder 42, a first pressing cylinder 43, a pressing block 44 and a buffer spring 45. The first side-pushing cylinder 42 is arranged on one side of the upper end surface of the limiting frame 5 through the pressing bracket 41. The first pressing cylinder 43 is connected to the movable end of the first side-pushing cylinder 42. The pressing block 44 is connected to the movable end of the first pressing cylinder 43. The first side-pushing cylinder 42 and the first pressing cylinder 43 cooperate to drive the pressing block 44 to cooperate with the interface end of the product 7. It can be seen that when the pressing and fixing is completed, the first side-pushing cylinder 42 and the first pressing cylinder 43 drive the pressing block 44 to press the interface end of the product 7 to prevent the interface from popping open during the pressing process. The buffer spring 45 is arranged between the movable end of the first pressing cylinder 43 and the pressing block 44 to avoid damage to the interface end of the product 7 caused by overpressure.
[0020] like Figure 1 and Figure 5 As shown, in this embodiment, the first push rod module 31 includes a first closing cylinder 311, a first lifting cylinder 312, a first push rod 313 and a second push rod 314. The first closing cylinder 311 is arranged at one end of the bottom plate 1 close to the first push block 9. The first lifting cylinder 312 is connected to the movable end of the first closing cylinder 311. The first push rod 313 and the second push rod 314 are connected to the movable end of the first lifting cylinder 312 through a first connecting plate 315. The first closing cylinder 311 and the first lifting cylinder 312 cooperate to drive the first push rod 313 and the second push rod 314 to cooperate with the first push block 9 and the first oblique push block 10 respectively. It can be seen that the first push rod 313 and the second push rod 314 are pushed synchronously, respectively driving the first push block 9 and the first oblique push block 10 to achieve the pressing and fixing of the product 7 and the test fixture 6.
[0021] like Figure 1 and Figure 6 As shown, in this embodiment, the second push rod module 32 includes a second closing cylinder 321, a second lifting cylinder 322 and a third push rod 323, the second closing cylinder 321 is close to one end of the second push block 11, the second lifting cylinder 322 is connected to the movable end of the second closing cylinder 321, and the third push rod 323 is connected to the movable end of the second lifting cylinder 322 through a second connecting plate 324, and the second closing cylinder 321 and the second lifting cylinder 322 cooperate to drive the third push rod 323 to cooperate with the second push block 11. It can be seen that the third push rod 323 realizes the pressing and fixing of the other end of the product 7, so that the product 7 as a whole does not deviate.
[0022] like Figure 1 , Figure 5 as well as Figure 6 As shown, in this embodiment, the ends of the first push rod 313, the second push rod 314 and the third push rod 323 are all provided with a first magnetic block 12, the upper ends of the first push block 9, the first oblique push block 10 and the second push block 11 are all provided with a second magnetic block 13, and the first magnetic block 12 is magnetically matched with the corresponding second magnetic block 13. It can be seen that the adsorption connected by the magnetic block uses the suction force of the magnet to adsorb the first oblique push block 10 so that it has a certain upward angle. The magnetic force is a flexible force, so during the advancement process, it will not cause a dead angle or friction between the pressure block and the track. Therefore, the test carrier can be closed with a success rate of 99.5%, and at the same time, it can ensure that the push block can be restored synchronously during the unlocking process of the test fixture 6, ensuring the smooth completion of the detection.
[0023] like Figure 2 and Figure 3 As shown, in this embodiment, a floating spring 14 is provided at the pressing end of the first oblique push block 10, and the first oblique push block 10 cooperates with the upper end surface of the test fixture 6 through the floating spring 14. It can be seen that the floating spring 14 provides a buffering effect during the process of the first oblique push block 10 pressing the test fixture 6.
[0024] like Figure 1 and Figure 4 As shown, in this embodiment, a limiting plate 15 is provided at the lower end of the limiting frame 5, and the limiting plate 15 cooperates with the outer side of the test fixture 6.

The positioning block 163 is connected to the movable end of the positioning cylinder 162, and the contact end of the positioning block 163 is provided with a contoured structure adapted to the diagonal position of the test fixture 6. The positioning cylinder 162 drives the positioning block 163 to move and cooperate with the limiting plate 15 to cooperate with the test fixture 6. It can be seen that the limiting plate 15 and the carrier positioning assembly 16 can ensure that the test fixture is fixed at the pressing detection station, and no deviation will occur, resulting in low detection accuracy.
[0025] like Figure 1 and Figure 2As shown, in this embodiment, a lifting port 17 is provided in the middle of the bottom plate 1, the lifting cylinder 21 is provided on one side of the lifting port 17, the lifting plate 22 is connected to the movable end of the lifting cylinder 21, and a positioning groove structure is provided on the upper end surface of the lifting plate 22, and the positioning groove structure cooperates with the test fixture 6. It can be seen that the lifting port 17 can increase the lifting stroke of the lifting cylinder 21, can better cooperate with the external manipulator for loading and unloading, and the positioning groove structure can ensure that the lifting process does not fall off.
[0026] The working principle of the present invention is as follows: before the equipment is started, the test fixture 6 to be tested is placed in the positioning groove structure on the upper end surface of the lifting plate 22 by an external manipulator, and the lifting cylinder 21 drives the test fixture 6 to rise. After the test fixture 6 reaches the testing position, the carrier positioning assembly 16 pushes the test fixture 6 to be fixed on the testing position, and the first side push cylinder 41 and the first pressing cylinder 42 drive the pressing block 44 to press the interface end of the product 7. After the positioning of the interface end is completed, the first push rod module 31 and the second push rod module 32 move synchronously, and the first push rod 313 and the second push rod 314 move synchronously. The rod 314 and the third push rod 323 are synchronously magnetically cooperated with the first push block 9, the first oblique push block 10 and the second push block 11, and push the first push block 9, the first oblique push block 10 and the second push block 11 to press the product 7 and the test fixture 6. After the pressing and fixing are completed, the inspection is carried out. After the inspection is completed, the first push rod module 31 and the second push rod module 32 are restored and the test fixture 6 is unlocked by the suction force of the magnetic block. Each component is restored in sequence, and the external manipulator replaces the test fixture 6 to be tested. The above steps are repeated to realize the magnetic pressing test of the product.
[0027] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
