During the movement of the aluminum ball pushing bar, the aluminum ball at the bottom of the aluminum ball feeding press seat will be pushed toward the feeding tube 43. The aluminum ball moves in the direction of the lock body, and finally the aluminum ball falls into the feed tube 43, and moves into the clamp rivet head 42 through the feed tube 43 and the side pin feed tube; then the aluminum ball pushing cylinder 44 is controlled to stop, and the side pin cylinder 39 is controlled to start. After the side pin cylinder 39 is started, the side pin punch fixing part 40 will be driven to move toward the lock body. During the movement of the side pin punch fixing part 40, the side pin punch 41 will be driven to move together, so that the side pin punch 41 enters the clamp rivet head 42 to clamp the side pin and the aluminum ball are pushed into the lock body together with the aluminum ball; after the first loading of the side pins and aluminum balls is completed, the lock body shifting cylinder 37 is controlled to start for a certain period of time, so that the lock body shifting seat 38 drives the lock body to move a certain distance in the direction of the first push beam cylinder 3, and then the lock body shifting cylinder 37 is controlled to pause, and the side pin pushing cylinder 44 and the aluminum ball pushing cylinder 45 are controlled to start and stop in turn again to complete the second loading of the side pins and aluminum balls, and the operation is repeated in sequence to complete the installation of the side pins on the upper side of the lock body.

[0033] After the side pin is installed, the spring feeding vibration plate 7 is controlled. After the spring feeding vibration plate 7 is started, the spring will be fed into the spring feeding tube; after a certain amount of spring is input into the spring feeding tube, the spring at the front end of the spring feeding tube will be pushed forward when the subsequent spring enters, so that the spring at the front end is pushed to the spring clamp arranged on the spring feeding tube away from the side of the first push beam cylinder 3; then the spring feeding cylinder connected to the spring clamp is controlled to start. After the spring feeding cylinder is started, it will push the spring clamp to move upward, so that the bottom end of the spring clamp can block the end of the spring feeding tube to prevent the spring from falling out; at the same time, it will also drive the spring pushed onto the spring clamp to move upward, and finally make the spring and the center axis of ... The central axis of one end of the lock beam is in the same horizontal plane; then the first push beam cylinder 3 is controlled to start, and the first push beam cylinder 3 will push the first mounting seat to move toward the lock body. During the movement of the first mounting seat, the lock beam fixture 6, the second push beam cylinder 4, the lock beam push piece 5 and the lock beam that slides onto the lock beam fixture 6 through the lock beam material rod 8 will be pushed to move together, so that one end of the lock beam located at the bottom is aligned with the spring and the spring is stuck on the lock beam, completing the first assembly; then the second push beam cylinder 4 is controlled to start, and the second push beam cylinder 4 will drive the lock beam push piece 5 to move toward the lock body. During the movement of the lock beam push piece 5, the bottom lock beam will be pushed to move toward the lock body, and finally the spring stuck in the lock beam The lock beam and the spring are assembled into the lock body together, completing the synchronous assembly of the lock beam and the spring. Compared with the previous method of assembling the spring first and then assembling the lock beam, while improving the work efficiency, it also reduces the footprint of the entire device; at the same time, when the lock beam pusher 5 pushes the lock beam onto the lock body, the lock beam clamp 53 will fix and guide the longer end of the lock beam to avoid the lock beam from deflecting during the movement, thereby ensuring the assembly accuracy; and the middle part of the lock beam clamp 53 is rotatably mounted on the lock beam pushing seat, and a pushing device for pushing one end of the lock beam clamp 53 up and down is provided on one side of the lock beam pushing seat, so that the lock beam clamp 53 can release the lock beam (that is, when the first push beam cylinder 3 pushes the first When the mounting seat moves, the lock beam pusher 5 will push the lock beam to move a certain distance in the direction of the lock body. During this process, the lock beam clamp 53 just limits and guides the longer end of the lock beam; and as the second push beam cylinder 4 continues to push the lock beam pusher 5 to move, the bent portion on the lock beam will move to the lock beam clamp 53. In order to ensure that the lock beam can continue to be pushed, it is necessary to loosen the lock beam clamp 53 through the pushing device to ensure the stable assembly of the lock beam); after the lock beam and the spring are assembled, the first push beam cylinder 3, the second push beam cylinder 4, the spring loading cylinder and the lock body moving cylinder 37 are controlled to stop, so that the lock body moving seat 38 and the first mounting seat are separated and automatically fall into the unloading channel to complete the unloading work.
