When the lifting cylinder 236 is working, it can control the up and down movement of the lifting platform 231, thereby conveniently controlling the vertical height of the lifting platform 231, and then conveniently transporting the carrier 3 horizontally. When the second motor 232 is working, it drives the rolling shaft 234 to rotate, and the chain between the rolling shaft 234 and the second motor 232 is not drawn in the attached drawings; when the rolling shaft 234 rotates, it drives the plastic chain 233 to move relative to the lifting platform 231, and the carrier 3 can be horizontally moved when placed on the plastic chain 233.

[0050] When the carrier 3 passes through the blocking device 4, the first cylinder 42 controls the limiter 45 to rotate, so that the roller 47 is in a low position, so that the carrier 3 can continue to move; when the carrier 3 is between the two blocking devices 4, the first cylinder 42 resets, and the limiter 45 automatically resets under the action of the torsion spring 46, so that the roller 47 is in a high position, so that the roller 47 and the limiter 45 will limit the front and rear positions of the carrier 3. Then the positioning jacking assembly 5 works to control the lifting of the carrier 3 to separate it from the chain belt on the double-speed chain assembly 2. At the same time, the clamping assembly 7 works to control the positioning member to fix the product.

[0051] The product passes through the clamping assembly 7 in sequence, and the multi-axis screw locking robot arm 6 arranged adjacent to the clamping assembly 7 will screw the product. After the screw assembly of the product is completed, the carrier 3 drives the product to move to the plug-in assembly 8 and the high-voltage detection assembly 9. The detection plug 83 on the plug-in assembly 8 is connected to the power meter. When the carrier 3 passes through the plug-in assembly 8, the fourth cylinder 82 controls the detection plug 83 to cooperate with the conductive seat 34 on the carrier 3, and then analyzes whether the product is qualified by reading the data on the power meter. When the carrier 3 passes through the high-voltage detection assembly 9, the fifth cylinder 92 works to control the high-voltage probe 94 to contact the outer shell of the product. At this time, the detection plug 83 on the plug-in assembly 8 is also inserted into the conductive seat 34 of the carrier 3. The product is tested at high voltage by the high-voltage probe 94 to detect the reliability and tolerance of the product under high voltage. After the product inspection is completed, the plug is removed by the plug-out assembly 10, and then transported to the next process through the unloading assembly 11.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
