[0002] A wiring terminal is a fitting product used to achieve electrical connection and is classified into the category of connectors in the industry. With the increasing degree of industrial automation and the increasingly strict and precise requirements for industrial control, the usage amount of wiring terminals is gradually increasing. At present, in the existing workshops, most of the assembly processes of the wiring terminal assembly machines adopt manual assembly and screwing, with low assembly efficiency, high manual labor intensity, and high labor costs. Especially for wiring terminals with relatively complex structures and more parts, their manual assembly has low assembly efficiency, is prone to missing parts, has a low qualified rate, and the production line is long. Summary of the Invention

The double turntables are used for working. The double turntables adopt multiple different workstations for assembling the relatively complex terminal blocks, greatly reducing the floor space occupied by the linear type. By using double discs instead of a large disc for working, the space is fully utilized, greatly saving the floor space. And the double turntables work simultaneously, improving the assembly efficiency. The first rotating material placing table is set up to realize the connection between the double turntables, solving the problem of reverse setting of part assembly in the double-disc working.

At the same time, another mechanical gripper of the first material transferring mechanism picks up the semi-finished product after the first rotating material placing table rotates 180 degrees and moves it above the loading station of the second turntable. During the movement of the mechanical gripper, the first rotating mechanism drives the first rotating material placing table to rotate 180 degrees to reset. After the mechanical gripper places the semi-finished product on the first rotating material placing table, the first rotating mechanism drives the first rotating material placing table to rotate 180 degrees; Step S7: The second turntable rotates into the third assembling station, and the feeding device on one side of the third assembling station places the assembled third substrate and the second pin on the feeding track above the second substrate; Step S8: The second turntable rotates into the second pressing station, and the driving cylinder above the second pressing station drives the pressing head to press down, so that the third substrate, the second pin and the semi-finished product are pressed and installed; Step S9: The second turntable rotates into the second inserting station, and the feeding device on one side of the second inserting station inserts the pressing piece on the feeding track into the third substrate; Step S10: The second turntable rotates into the fourth assembling station, and the feeding device on one side of the fourth assembling station places the cover plate on the feeding track above the third substrate; Step S11: The second turntable rotates into the third pressing station, and the driving cylinder above the third pressing station drives the pressing head to press down, so that the cover plate and the third substrate are pressed and installed into a finished product;Step S12: The second turntable rotates and enters the second blanking station.

When the mechanical gripper is moving, the second rotating mechanism drives the second rotating material placement table to rotate 180 degrees and reset; Step S13: The detection device determines whether the finished product on the finished product inspection station is qualified. If the product is qualified, the driving component drives the blanking chute to enter between the finished product inspection station and the receiving frame, and the product falls into the blanking chute. If the product is unqualified, the driving component drives the blanking chute to withdraw from between the finished product inspection station and the receiving frame, and the product falls into the receiving frame.;
