[0038] like Figure 4 , Figure 5 As shown, a transmission plate 3 is connected to the loading tray 1, and an accessory 100 is loaded in the loading tray 1. The working principle of the loading tray 1 is the same as that of the vibrating loading tray in the prior art, and will not be described in detail here.

When the card slot on the material moving plate 8 is connected with the transmission slot on the transmission plate 3, the material moving plate 8 receives the accessories 100 to realize loading. When the material moving plate 8 moves toward the welding mechanism 4, the material moving plate 8 blocks the accessory 100 on the transmission plate 3 from moving forward. The position change of the material moving plate 8 is used to realize the pause of loading. Compared with the method of using an electrical switch to realize the pause of loading, this method has higher stability.

[0040] like Figure 4 , Figure 8 , Fig. 9 As shown, the loading mechanism 5 includes a bottom plate 501, on which a plurality of clip strips 504 are disposed, and between two adjacent clip strips 504 a long strip-shaped transmission channel parallel to the X-axis is formed, and the accessories 200 are distributed in an array in the transmission channel.

[0041] The bottom plate 501 is driven by a motor 505 to move along the Y axis. Specifically, the bottom plate 501 is installed on the movable plate 502. A groove is provided on the bottom plate 501. A clamping block 503 is arranged at the position of the movable plate 502 corresponding to the groove. The bottom plate 501 is placed on the movable plate 502.

[0042] Please refer to Fig. 9 The movable plate 502 is connected to the slider 2 512, the slider 2 512 is threadedly connected to the screw 2 513, one end of the screw 2 513 is connected to the driving end of the motor 1 505, a guide rod 506 is arranged on the side of the screw 2 513, the movable plate 502 is connected to the guide rod 506, the motor 1 505 drives the screw 2 513 to rotate and drives the slider 2 512 to move on the screw 2 513.

[0043] The two ends of screw rod 2 513 and guide rod 506 are connected to the auxiliary plate and mounted under the base plate 501. Motor 1 505 is installed on the auxiliary plate, and screw rod 2 513 is driven to rotate by motor 1 505. Since screw rod 2 513 and slider 2 512 are threadedly connected, slider 2 512 is driven to move on screw rod 2 513, thereby driving the movable plate 502 and the base plate 501 to move, adjusting the position of the base plate 501, and improving the stability of the movement of the movable plate 502 through the guide rod 506.

[0044] In addition, a connecting rod 510 driven by the second motor 507 to move along the X-axis is mounted on the bottom plate 501, and one end of the connecting rod 510 is connected to a pushing block 511 adapted to the transmission channel. Specifically, one end of the connecting rod 510 away from the pushing block 511 is connected to the slider 1 508, the slider 1 508 is threadedly sleeved with the screw 1 509, one end of the screw 1 509 is connected to the driving end of the second motor 507, and the second motor 507 drives the screw 1 509 to rotate and drives the slider 1 508 to move on the screw 1 509.

[0045] The motor 1 505 drives the bottom plate 501 to move along the Y axis, adjusts the position of the bottom plate 501, and makes the push block 511 engage with the transmission channel on the bottom plate 501. Then, when the motor 2 507 drives the connecting rod 510 to move along the X axis, the push block 511 pushes the second accessory 200 in the corresponding transmission channel to move toward the welding mechanism 4. The positions of the bottom plate 501 and the push block 511 are adjusted by the driving of the motor 1 505 and the motor 2 507, so as to realize the sequential and single loading of the second accessory 200.

[0046] like Figure 4 , 10 As shown, the material transfer mechanism 6 includes a suction piece 605 for transferring accessory 1 100 and a clamp 607 for transferring accessory 2 200 . The clamp 607 is also used to transfer the workpiece after welding.

[0047] Please refer to Fig.10 , the adsorption part 605 is driven by the cylinder three 604 to move up and down, the cylinder three 604 is installed on the mobile slide 1 602, the clamp 607 is driven by the cylinder five 608 to move along the X axis, the clamp 607 and the cylinder five 608 are driven by the cylinder four 606 to move up and down, the cylinder four 606 is installed on the mobile slide 2 603, the mobile slide 1 602, the mobile slide 2 603 are slidably connected with the mobile slide rail 601. The working principle between the mobile slide 1 602, the mobile slide 2 603 and the mobile slide rail 601 is the same as the working principle of the electric slide rail, and the movement of the mobile slide 1 602 and the mobile slide 2 603 can also be realized by the mobile module, and the main purpose is to adjust the position of the adsorption part 605 and the clamp 607.

[0048] In addition, a receiving tray 7 is arranged beside the material transfer mechanism 6, and a guide plate arranged obliquely is arranged above the receiving tray 7. The clamp 607 includes a clamping block driven by a clamping claw cylinder, and the clamp 607 is used to clamp the second accessory 200 on the bottom plate 501 and place it on the first accessory 100 on the assembly plate 401 for clamping, or to transfer the welded workpiece from the assembly plate 401 to the receiving tray 7. The specific structure of the clamping block is not limited, and it only needs to be able to grab the second accessory 200.

[0049] Working principle: When the elastic thin plate automatic welding machine is in use, the accessory 100 is transferred from the loading tray 1 to the array distribution on the transmission plate 3, and then the moving plate 8 is driven to move by the cylinder 9, so that the card slot on the moving plate 8 is connected with the transmission slot on the transmission plate 3, and the moving plate 8 receives the accessory 100, and then the moving plate 8 is moved toward the welding mechanism 4 by the cylinder 9. At this time, the moving plate 8 blocks the accessory 100 on the transmission plate 3 from continuing to move forward, so that the loading is suspended.

[0050] At the same time, the position of the bottom plate 501 is adjusted by driving the motor 1 505 , and then the position of the push block 511 is adjusted by driving the motor 2 507 , and the push block 511 pushes the accessory 2 200 in the transmission slot on the bottom plate 501 to move toward the welding mechanism 4 .

[0051] The material transfer plate 8 and the material loading mechanism 5 realize the loading of the accessory 1 100 and the accessory 2 200 respectively. At this time, the movable slide 1 602 drives the adsorption member 605 to move so that the adsorption member 605 follows the action of the cylinder 3 604, and the accessory 1 100 on the material transfer plate 8 is adsorbed and transferred to the assembly plate 401 in the welding mechanism 4 for clamping. Then, the movable slide 2 603 drives the clamp 607 to move so that the clamp 607 follows the action of the cylinder 4 606 and the cylinder 5 608 to clamp the accessory 2 200 on the bottom plate 501 and transfer it to the assembly plate 401 for clamping with the accessory 1 100.

[0052] During welding, cylinder 2 407 drives slide 2 405 to move to welding head 1 408 to enter the corresponding welding groove, and makes welding head 1 408 push slide 1 404 to move to welding head 2 409 to enter the corresponding welding groove. After welding head 1 408 and welding head 2 409 are in place, accessory 1 100 and accessory 2 200 are welded by existing resistance welding technology. After welding is completed, cylinder 2 407 drives slide 2 405 to reset, and slide 1 404 is reset through the elastic part.

[0053] At this time, the second slide 603 is used to drive the clamp 607 to move, so that the clamp 607 transfers the welded workpiece to the receiving tray 7.
