[0038] In this embodiment, when the position of the workpiece needs to be adjusted, the first electric push rod 42 and the second electric push rod 43 are started respectively, and the first electric push rod 42 and the second electric push rod 43 will respectively push the first adjustment plate 44 and the second adjustment plate 45 to move, and the first adjustment plate 44 and the second adjustment plate 45 are vertically arranged and connected by the transmission block 413, which will drive the transmission block 413 to move in a two-dimensional plane in a specific direction, and the mobile clamping table 46 at the top of the transmission block 413 will move accordingly, and the universal wheels 47 at the four corners of the bottom end of the mobile clamping table 46 roll on the inner wall of the limit table 41, playing a role of auxiliary support and smooth movement, thereby realizing the precise adjustment of the position of the mobile clamping table 46 within the range of the limit table 41, so as to weld at different welding positions of the workpiece to meet the position requirements of subsequent welding.

[0039] In a further embodiment, a mounting base 48 is fixedly connected to the front side of the mobile clamping platform 46, a servo motor 49 is fixedly installed inside the mounting base 48, a bidirectional screw rod 410 is fixedly sleeved on the output shaft of the servo motor 49, the bidirectional screw rod 410 is rotatably connected to the inner wall of the mobile clamping platform 46, the outer surfaces of both ends of the bidirectional screw rod 410 are threadedly connected with a screw sleeve 411, and the top of the screw sleeve 411 is fixedly connected to a first clamping plate 412.

[0042] In this embodiment, the shelf plate 414 provides an additional support plane for placing the workpiece on the movable clamping table 46, so that the relay can be placed more stably, avoiding shaking or tipping before being clamped, and improving the convenience of operation.

[0043] In a further embodiment, a mobile motor 51 is symmetrically arranged on the top of the mounting platform 3, and a gear 52 is fixedly sleeved on the output shaft of the mobile motor 51. A rack 53 is meshingly installed on the outer surface of the gear 52, and the bottom end of the rack 53 is fixedly connected to the top wall of the mounting platform 3. A mobile plate 54 is fixedly connected to the bottom end of the mobile motor 51, and support rods 55 are fixedly sleeved at both ends of the mobile plate 54, and the support rods 55 are slidably connected to the inner wall of the mobile groove 31.

[0044] In this embodiment, the moving motor 51 is first started, and its output shaft drives the gear 52 to rotate. The gear 52 will roll along the rack 53 toward one end of the mounting table 3. During the rolling of the gear 52 along the rack 53, the moving motor 51 will drive the support rod 55 to slide in the moving groove 31 through the moving plate 54, so that the support rod 55 and the related components at the bottom end can be moved accurately, and the moving motor 51 can rotate forward or reverse, and correspondingly drive the gear 52 to rotate forward and reverse, thereby making the support rod 55 move back and forth, and finally making the support rod 55 and the related components at the bottom end able to flexibly adjust their positions according to different processing steps, so as to realize feeding and picking operations, thereby improving the versatility and flexibility of the device.

[0045] In a further embodiment, the bottom end of the support rod 55 is fixedly connected to a mounting plate 56 , and both ends of the top end of the mounting plate 56 are fixedly connected to a first cylinder 57 . The telescopic shaft of the first cylinder 57 passes through the mounting plate 56 and is fixedly sleeved with a lifting plate 58 .

[0046] In this embodiment, when the support rod 55 moves, it drives the mounting plate 56 to move. When the mounting plate 56 reaches a suitable position, the first cylinder 57 is started, and its telescopic shaft drives the lifting plate 58 to move downward, so that the second clamping plate 513 at one end of the bottom of the lifting plate 58 is aligned with the workpiece to be processed inside the feed plate 7, and the second clamping plate 513 at the other end of the bottom of the lifting plate 58 is aligned with the workpiece processed inside the movable clamping table 46, thereby achieving preliminary position adjustment for subsequent processing operations.

[0047] In a further embodiment, a slide groove 510 is opened inside the lifting plate 58, and a third electric push rod 59 is fixedly installed on both sides of the top of the lifting plate 58. The telescopic axis of the third electric push rod 59 is fixedly sleeved with a slider 511, and the slider 511 is slidably connected to the inner wall of the slide groove 510. The bottom end of the slider 511 is fixedly connected to a connecting plate 512, and both ends of the connecting plate 512 are fixedly connected to a second clamping plate 513.

[0048] In this embodiment, when the lifting plate 58 is lifted to a suitable position, the third electric push rod 59 is started, and the third electric push rod 59 pushes the slider 511 to approach each other in the slide groove 510. When the slider 511 moves, the second clamping plates 513 at both ends thereof are driven by the connecting plate 512 to clamp and fix the workpiece to be processed and the workpiece to be processed respectively. Then, the first cylinder 57 drives the workpiece to be processed and the workpiece to be processed to rise through the lifting plate 58, and then the moving motor 51 drives the gear 52 to continue to roll, so that the workpiece to be processed and the workpiece to be processed move toward the discharge plate 8.

[0049] When the workpiece to be processed moves to the top of the mobile clamping table 46, the moving motor 51 is stopped, and then the first cylinder 57 drives the workpiece to be processed and the processed workpiece to descend through the lifting plate 58, and then the telescopic shaft of the third electric push rod 59 is retracted, thereby releasing the clamping operation of the second clamping plate 513 on the workpiece to be processed and the processed workpiece. At this time, the workpiece to be processed is placed on the upper end of the shelf plate 414, and the processed workpiece is placed on the discharge plate 8. Finally, the moving motor 51 is started to drive the related components below to return to the left end of the workbench 1, thereby realizing the automatic operation of feeding and discharging, greatly reducing the manual operation time, improving production efficiency, and improving the versatility of the equipment.

[0050] In a further embodiment, a second cylinder 6 is fixedly mounted at the center of the top of the mounting platform 3 , a telescopic shaft of the second cylinder 6 passes through the mounting platform 3 and is fixedly sleeved with a mounting plate 91 , and a spot welding head 10 is arranged inside the mounting plate 91 .

[0051] In this embodiment, after the workpiece to be processed is moved to a suitable position above the mobile clamping table 46 and placed, the second cylinder 6 is started, and its telescopic shaft drives the spot welding head 10 to descend to a position where spot welding can be performed on the workpiece through the mounting plate 91. After the spot welding process is completed, the second cylinder 6 lifts the spot welding head 10 to make it leave the processed workpiece. The entire device is operated according to the discharge process, and the mobile motor 51 drives the workpiece to move toward the discharge plate 8 to avoid interference such as collision during the movement of the workpiece, thereby realizing automated production.

[0052] In a further embodiment, a slot 92 is opened inside the mounting plate 91, and a latch tongue 93 is slidably connected inside the slot 92. The latch tongue 93 is embedded in the top notch of the spot welding head 10. One end of the latch tongue 93 is fixedly connected to a pull rod 95, and one end of the pull rod 95 passes through the inner wall of the slot 92 and extends to the outside.

[0053] In this embodiment, when the spot welding head 10 needs to be disassembled, the operator can pull the pull rod 95, and the pull rod 95 will drive the latch 93 to slide in the slot 92. As the latch 93 slides, the spring 94 contracts, and the latch 93 will gradually disengage from the slot at the top of the spot welding head 10. At this time, the spot welding head 10 is no longer engaged and fixed with the mounting plate 91, and the spot welding head 10 can be easily removed from the mounting plate 91, which is convenient for maintenance and replacement of spot welding heads 10 of different specifications, thereby improving the flexibility of equipment maintenance and use.

[0054] In a further embodiment, a spring 94 is sleeved on the outer surface of one end of the pull rod 95 close to the latch tongue 93 , one end of the spring 94 is fixedly connected to one end of the latch tongue 93 , and the other end of the spring 94 is fixedly connected to the inner wall of the slot 92 .

[0055] In this embodiment, after the spot welding head 10 is installed, the elastic force of the spring 94 can ensure that the spot welding head 10 will not be separated from the installation plate 91, thereby ensuring the tightness of the engagement between the latch 93 and the spot welding head 10.

[0056] In a further embodiment, a feed plate 7 is fixedly connected to the left end of the limiting platform 41 , and a discharge plate 8 is fixedly connected to the right end of the limiting platform 41 .

[0057] In this embodiment, by setting the feed plate 7 and the discharge plate 8, the entire work flow of the device from feeding to discharging is improved, so that the production and processing of the workpiece can be carried out more efficiently and smoothly, while ensuring the stability and integrity of the workpiece during the feeding and discharging process.
