[0082] Embodiment three

[0083] The camera SMA base spring automatic suction and conveying spot welding machine provided in embodiment two is further optimized, and specifically, as shown in Figure 1 、 Figures 5-7As shown, the shell feeding mechanism 4 includes a shell conveying device 401 and a shell winding roller 404.

The top of the shell conveying device 401 is provided with a position sensor 403 at the parallel position of the shell feeding mechanism 6. The position sensor 403 can identify the position of the shell. When the shell is identified by the position sensor 403, the position sensor 403 sends a command to the shell feeding mechanism 6, so as to control the shell feeding mechanism 6 to grab the shell and fill the shell into the shell limiting groove 304.

[0084] The shell winding roller 404 is arranged at the tail end of the shell conveying device 401. The shell winding roller 404 can wind the shell, so as to arrange the shell pasted on the winding film in batches on the equipment. During processing, the end of the winding film is passed through the shell guide groove 402 and connected with the driving equipment. When the driving equipment winds the winding film, the shell winding roller 404 starts to feed.

A picking machine arm 603 is installed on the horizontal moving platform 602, and the picking machine arm 603 can grab the bullet and place it in the bullet limiting groove 304.

[0088] Through the above technical solution, the horizontal moving platform 602 first drives the picking machine arm 603 to grab the bullet and feed it into the bullet limiting groove 304 on one side. When the feeding on one side is completed, feeding on the other side is performed. The feeding on both sides is alternately and cyclically performed, which reduces the waiting time for feeding of the equipment and improves the operation rate of the equipment. In the process of moving of the picking machine arm 603, the bullet will pass above the visual recognition part 5 to recognize the angle of the bullet.

[0089] Embodiment five

[0091] Through the above technical solution, the support frame 701 can support the welding device 702, so that a gap for movement of the welding jig 3 is left between the bottom of the welding device 702 and the top of the jig conveying rail 2. When the welding jig 3 drives the SMA base and the bullet to enter directly below the welding device 702, the welding device 702 controls the welding heads to descend and uniformly weld all the bullets.

[0092] Embodiment six

[0093] The camera SMA base bullet automatic suction and conveying spot welding machine provided in the above embodiments is further optimized, as shown in Figure 1 and Figure 5As shown, the top of the support frame 1 is provided with a safety auxiliary mechanism 8, which includes a grating emitting part 801 and a grating receiving part 802, and the grating emitting part 801 and the grating receiving part 802 are opposite to each other to form a grating, and the grating emitting part 801 and the grating receiving part 802 are located outside the discharge ends of the two jig conveying rails 2. During the operation of the equipment, if an object is between the gratings and the opposite laser signals are cut off, the grating emitting part 801 will send a stop command to the power distribution and signal relay mechanism 10, and the stop command will be forwarded to all equipment through the power distribution and signal relay mechanism 10, so as to improve the safety of the equipment.

[0094] The use process of the camera SMA base spring piece automatic suction and conveying spot welding machine is as follows: the operator places the SMA base to be welded in the limiting base groove 302, and limits through the spring piece limiting cover plate 303. Then, the jig conveying rail 2 drives the welding jig 3 to move to a position flush with the visual identification part 5. At this time, the spring piece conveying device 401 conveys the spring piece to the position of the position sensor 403, and stops conveying when the position sensor 403 identifies the spring piece, and drives the horizontal moving platform 602 to drive the picking machine arm 603 to grab the spring piece from the spring piece conveying device 401 to the spring piece limiting groove 304 for feeding. In the feeding process of the spring piece driven by the picking machine arm 603, the spring piece is identified by the visual identification part 5, and whether the angle of the spring piece is correct is confirmed, and if not, the picking machine arm 603 is adjusted through rotation. After the spring piece feeding is completed, the jig conveying rail 2 continues to drive the welding jig 3 to move to the position directly below the welding device 702, and drives the welding head to descend to weld the spring piece through the welding device 702. At this time, after welding is completed, the jig conveying rail 2 continues to drive the welding jig 3 to return to the initial feeding position, and the SMA base welded is taken out manually, and the SMA base to be welded is filled. The above steps are repeated.
