Assembly stage: the pneumatic clamping assembly 504 clamps the guide rail and rotates, and drives the guide rail to translate to the assembly position through the drive of the screw module 503 to assemble the terminal; after the assembly is completed, the screw module 503 transports the assembled terminal block to the discharge conveying device 700.

When the guide rail cutting device 600 receives a cutting instruction, the cutting cylinder 601 starts to work, and its output shaft drives the cutting tool 602 to perform telescopic movement, thereby achieving cutting of the guide rail; during the cutting process, the cutting edge of the cutting tool 602 will fit closely to the guide rail material and cut it off through the action of shear force; at the same time, the cutting device body 603 will ensure that the movement trajectory of the cutting tool 602 is stable and accurate, so as to ensure the flatness of the cutting surface and the accuracy of the cutting size.

[0073] While shearing the guide rail, the terminal loading device 100 rotates to the target position and pushes the required terminals in the storage slot 103 to the loading slot 106; after the required number of terminals are loaded, the terminal loading device 100 rotates until the storage slot 103 is aligned with the loading baffle 107 to prevent the terminals in the loading slot 106 from being taken away by the terminal clamping device 200 and then continuing to load, and also to avoid the continuous accumulation of terminals in the loading slot 106 affecting the terminal clamping device 200 from clamping the terminals.

[0074] Step 200: Terminal block assembly: The terminal clamping device 200 removes the terminal from the loading slot 106 and installs the terminal on the guide rail above the guide rail clamping device 500; after the terminal is removed, the terminal loading device 100 also continues to load at the same time; during the terminal assembly process, the guide rail loading device 400 transfers the guide rail to the bottom of the guide rail clamping device 500 for clamping, and the guide rail cutting device 600 cuts the guide rail.

[0075] Step 300: Terminal block conveying: After the terminal block is assembled, the guide rail clamping device 500 moves to convey the terminal block to the discharge conveying device 700 and then to the finished product hopper 800; after the conveying is completed, the guide rail clamping device 500 rotates to rotate the cut guide rail at the bottom to the upper terminal installation position, waiting for the next terminal installation.

[0076] After the terminal block is assembled, the pneumatic clamping assembly 504 above the guide rail clamping device 500 moves toward the direction close to the discharge conveying device 700 through the upper screw module 503, moves the terminal block to the discharge conveying device 700, and then is transported to the finished product hopper 800 by the discharge conveying device 700;

[0077] After the finished terminal block is fed into the discharge conveying device 700, the guide rail clamping device 500 rotates in the opposite direction of the last time, and the guide rail that has been prepared by the guide rail clamping device 500 is rotated upward to assemble the next terminal block.

[0078] Step 400: assemble the terminal block repeatedly.
