[0022] like Figures 1-4As shown, a welding device according to one embodiment of the present invention includes a machine base 1. A transport device 2, a processing device 3, and an output device 4 are sequentially arranged on the machine base 1 along the direction of movement of the workpiece. The processing device 3 includes a disc 31, a first drive block 32, a positioning mechanism 33, a spot welding mechanism 34, and a clamping mechanism 35. The first drive block 32 is disposed on the machine base 1, and the disc 31 is disposed on the output end of the first drive block 32. The first drive block 32 is used to drive the disc 31 to rotate. The disc 31 is provided with a plurality of positioning fixtures 6 for placing and fixing the workpiece. The positioning mechanism 33 is used to drive the workpiece to be fixed on the positioning fixtures 6. The clamping mechanism 35 is used to drive the workpiece to move from the positioning fixtures 6 to the output device 4.
[0023] The aforementioned welding equipment uses a first drive block 32 to drive the disc 31 to rotate periodically, allowing multiple positioning fixtures 6 to sequentially pass through transportation, welding, and output processes, achieving parallel operation and improving equipment utilization. The disc 31 structure integrates the processing device 3 into a single rotating unit, reducing material transfer distance and lowering the equipment footprint compared to traditional linear layouts. This welding equipment solves the problems of low overall equipment utilization and low space utilization in traditional processing equipment.
[0024] like Figures 1-3As shown, in one embodiment, the disc 31 is provided with a plurality of first guide rails 5, and each disc 31 is respectively connected to one positioning fixture 6; the transport device 2 includes a transport mechanism 21, a pushing mechanism 22 and a second guide rail 23; the transport mechanism 21 has two parallel conveyor belts; the two conveyor belts cooperate to move the workpiece onto the second guide rail 23; the pushing mechanism 22 includes a first bracket 221, a first linear module 222, a first cylinder 223 and a first abutting block 224; the first bracket 221 is disposed on the... On the machine base 1, the first linear module 222 is mounted on the machine base 1; one end of the first cylinder 223 is connected to the moving end of the first linear module 222, and the other end of the first cylinder 223 is connected to the first abutment block 224; the first cylinder 223 is used to drive the first abutment block 224 to move up and down; the first linear module 222 and the first abutment block 224 cooperate to push the workpiece from the conveying mechanism 21 to the second guide rail 23; a gap is formed between the two conveyor belts for the first abutment block 224 to be inserted. In this way, the multiple first guide rails 5 set on the disc 31 correspond one-to-one with the positioning fixture 6, and combined with the coordinated guidance of the parallel conveyor belt and the second guide rail 23 in the transport device 2, the transfer path of the workpiece from transport to positioning is strictly aligned with the workstation of the disc 31; the pushing mechanism 22 adopts a composite drive structure of the first linear module 222 and the first cylinder 223, the linear module controls the horizontal pushing stroke, and the cylinder drives the first abutment block 224 to move up and down vertically. This design, combined with the gap structure between the two conveyor belts, allows the abutment block to precisely insert into the gap and complete the "descend-push-reset" action when pushing the workpiece, completely avoiding the jamming problem caused by friction between the traditional push rod mechanism and the conveyor belt surface; like Figures 1-4As shown, in one embodiment, the positioning mechanism 33 includes a second support 331, a second linear module 332, a second cylinder 333, and a second abutting block 334; the second abutting block 334 includes a first abutting portion 3341 and a second abutting portion 3342; the first abutting portion 3341 and the second abutting portion 3342 are vertically connected; the second support 331 is disposed on the machine base 1, the second linear module is disposed on the second support 331, one end of the second cylinder 333 is connected to the moving end of the second linear module 332, and the other end of the second cylinder 333 is connected to the first abutting portion 3341; the second cylinder 333 is used to drive the second abutting block 334 to move up and down; the second linear module 332 and the second abutting portion 3342 cooperate to push the workpiece sequentially through the second guide rail 23 and the first guide rail 5 and place it on the positioning fixture 6; the second cylinder 333 and the first abutting portion 3341 cooperate to press the workpiece onto the positioning fixture 6. Thus, the second linear module 332 drives horizontal pushing, and the second cylinder 333 controls vertical pressing, forming a "pushing then pressing" sequence of actions; through the vertical connection between the first abutting part 3341 and the second abutting part 3342 of the L-shaped second abutting block 334, when the second cylinder 333 presses down, the second abutting part 3342 forms a surface contact and presses against the positioning fixture 6, while the first abutting part 3341 constrains the horizontal displacement of the workpiece through lateral limiting.
[0025] like Figures 1-4 As shown, in one embodiment, the positioning fixture 6 includes a positioning base 61, a third cylinder 62, and a first clamping block 63. Both the positioning base 61 and the third cylinder 62 are mounted on the disc 31, and the third cylinder 62 is connected to the first clamping block. The third cylinder 62 drives the first clamping block 63 to cooperate with the positioning base 61 to fix the workpiece. The spot welding mechanism 34 includes a third support, a lifting device, and a spot welding head. The third support is mounted on the machine base 1, the lifting device is mounted on the third support, and the spot welding head is mounted on the moving end of the lifting device. The lifting device drives the spot welding head to move up and down. Thus, by using the third cylinder 62 in the positioning fixture 6 to drive the first clamping block 63 and the positioning base 61 to form a dynamic clamping force system, and by adjusting the cylinder pressure in real time, it can accommodate workpieces of varying thicknesses.
[0026] like Figures 1-4As shown, in one embodiment, the processing device 3 further includes a detection mechanism 7. The workpiece passes sequentially on the processing device 3 through the positioning mechanism 33, the spot welding mechanism 34, the detection mechanism 7, and the clamping mechanism 35. The detection mechanism is used to detect whether the spot welding on the workpiece is qualified. The clamping mechanism 35 includes a fourth bracket, a third linear module, a fourth cylinder, and an electric clamping head. The fourth bracket is mounted on the machine base 1, and the third linear module is mounted on the fourth bracket. The fourth cylinder is mounted on the moving end of the third linear module, one end of the fourth cylinder is connected to the electric clamping head, and the other end of the fourth cylinder is connected to the moving end of the third linear module. The output device 4 includes a first conveyor belt and a second conveyor belt. The clamping mechanism 35 is used to clamp and move the workpiece that has been detected as qualified by the detection mechanism 7 onto the first conveyor belt. The clamping mechanism 35 is also used to clamp and move the workpiece that has been detected as unqualified by the detection mechanism 7 onto the second conveyor belt. Thus, the inspection mechanism 7 performs real-time quality judgment on the spot welding after spot welding, and the clamping mechanism 35 separates qualified / unqualified workpieces to form a fully automatic quality closed loop.
[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
