[0031] Working principle of the invention: This invention incorporates a transfer component, enabling staggered and alternating operations for pressing and welding processes, significantly reducing process waiting time. It also includes a feeding transfer component, pressing component, welding component, roller pressing component, and unloading component, integrating the entire process of feeding, pressing, welding, long and short side roller pressing, and unloading into a single device. Combined with a dual-gripper feeding transfer structure, it achieves seamless process connection, avoiding the time-consuming long-distance transfers between multiple machines, effectively improving equipment uptime and overall production line cycle time. The integrated and compact layout also significantly reduces the equipment's footprint, improving workshop space utilization and meeting the high-efficiency production requirements of large-scale power battery production.

[0032] Specifically, the battery cells to be processed are conveyed via the feeding conveyor belt 21 of the feeding logistics module 2. The direction of the feeding conveyor belt 21 is the X-axis direction, such as... Figure 1As shown; the inner feeding guide plate 23 divides the two parallel feeding guide side plates 22 into two parallel conveying channels. Each conveying channel can convey one battery cell to be processed from front to back (X-axis direction). After the battery cell to be processed is conveyed to the end of the conveying channel, the feeding positioning plate 25 gradually reduces the size of the conveying channel to limit the battery cell to be processed at the end of the conveying channel. In addition, the positioning rod 15 limits the battery cell to be processed in the horizontal direction, that is, closes the end conveying of the conveying channel to prevent the battery cell to be processed from leaving the feeding conveyor belt 21. At the same time, a blocking mechanism can be set to block and intercept the next battery cell to be processed, realizing a buffer function. The blocking mechanism can cause the blocking plate 13 to intercept the subsequent battery cell to be processed through the blocking Y-axis moving mechanism 14. The feeding clamping mechanism 31 of the battery cell feeding module 3 can clamp and move the battery cells to be processed on the feeding conveyor belt 21, using the feeding lifting mechanism 33 and the feeding Y-axis moving mechanism 32. Figure 1 The Y-axis direction (left and right) is used to clamp the battery cell to be processed and transfer it to the rotary lifting fixture 71. The rotary lifting fixture 71 is used to position and clamp the battery cell to be processed, meeting the processing requirements of rotation, lifting, and forward, backward, left and right movement. The battery cell to be processed, fixed by the rotary lifting fixture 71, is transported by the fixture X-axis moving mechanism 72. Figure 1 (The X-axis direction is the front-to-back direction). The battery cell to be processed, fixed by the rotating lifting fixture 71, first passes through the pressing mechanism. The pressing mechanism presses the cover plate on the battery cell to be processed. After being pressed, the battery cell to be processed will continue to be transported from front to back to the welding mechanism. The welding head 81 of the welding mechanism is used to weld the battery cell to be processed. Finally, the battery cell to be processed after being welded by the welding mechanism is moved to the loading rack 1 by the fixture X-axis moving mechanism 72. After the rotating lifting fixture 71 is released, the battery cell transfer module 4 clamps and transfers the welded battery cell to the roller pressing seat 91 for clamping. The roller pressing Y-axis moving mechanism 916 drives the battery cell to be processed on the roller pressing seat 91 to pass through the short side roller pressing mechanism 92 and the long side roller pressing mechanism 93 in sequence for short side roller pressing and long side roller pressing. Finally, the roller pressing process is completed. The battery cell unloading module 10 transfers the roller-pressed battery cell to the unloading logistics module 11 for unloading, completing a series of processing steps. The feeding lifting mechanism 33, unloading lifting mechanism 103, pressing lifting component 62, and welding lifting component 82 can all be selected from cylinders or linear modules. In this embodiment, the cover plate can be placed on top of the battery cell to be processed during feeding.

[0033] Specifically, the starting end of the roller pressing Y-axis moving mechanism 916 is located near the end of the feeding conveyor belt 21, and the end of the roller pressing Y-axis moving mechanism 916 is located at the starting end of the unloading conveyor belt; as Figure 1As shown, the roller pressing Y-axis moving mechanism 916 is arranged from left to right and conveys the roller pressing seat 91 and the battery cell to be processed; the feeding conveyor belt 21 conveys the battery cell to be processed from front to back, and the unloading conveyor belt conveys the battery cell to be processed from left to right; the feeding clamping mechanism 31 at the front end of the feeding rack 1 can be arranged above the end of the feeding conveyor belt 21, and the transfer clamping mechanism 41 at the rear end of the feeding rack 1 can be arranged above the beginning of the roller pressing Y-axis moving mechanism 916; the unloading clamping mechanism 101 can be arranged between the roller pressing Y-axis moving mechanism 916 and the unloading conveyor belt. This layout can realize high-efficiency processing of each mechanism in this embodiment, smooth connection of each process, and strong stability. The unloading guide mechanism on the unloading conveyor belt can refer to the loading guide mechanism, but is not limited to the structure of the loading guide mechanism. In this embodiment, two unloading guide side plates arranged parallel to each other along the conveying direction of the unloading conveyor belt can be selected to form an unloading channel to complete the unloading of a single processed cell (or battery). Specifically, an unloading positioning plate can also be set. When an unloading guide inner plate is set, the unloading positioning plate can be selectively set along with the unloading guide inner plate (refer to the loading guide inner plate 23), and the distance between the unloading positioning plate and the unloading guide side plate should not be less than the size of the cell or battery to avoid obstructing the unloading of the cell or battery.

[0034] Specifically, in this embodiment, there are two transplanting modules 7 arranged side by side, which can process two cells to be processed at the same time. Similarly, there are two pressing mechanisms to meet the processing requirements of the two transplanting modules 7. In this embodiment, one welding mechanism can be set. The welding mechanism can move left and right along the Y-axis and adjust its position to weld the two cells to be processed in sequence according to different cycles.

[0035] In this embodiment, the short-side Y-axis moving mechanism 922 can drive the two oppositely arranged short-side pressing arms 921 to move closer or further apart, thereby causing the short-side pressing arms 921 to clamp or loosen the short side of the battery cell to be processed; the short-side X-axis driving mechanism 923 can drive the two oppositely arranged short-side pressing arms 921 to move along the X-axis direction, thereby performing moving pressing on the short side of the battery cell to be processed, and the short-side pressing roller 924 rotates around the vertical axis, with the rotating surface of the short-side pressing roller 924 in contact with the short-side surface of the battery cell to be processed; similarly, the long-side X-axis moving mechanism 931 can drive the two oppositely arranged long-side pressing arms 932 The two long-side rollers 932 move closer or further apart, causing them to clamp or release the long side of the battery cell to be processed. The long-side X-axis drive mechanism 933 can further drive the two oppositely arranged long-side rollers 932 to move along the X-axis direction, thereby performing fine-tuning roller pressing on the long side of the battery cell to be processed. The long-side roller 934 rotates around the vertical axis, and the rotating surface of the long-side roller 934 is in contact with the long-side surface of the battery cell to be processed. The roller pressing Y-axis moving mechanism 916 drives the roller pressing seat 91 to move in the Y-axis direction (from left to right), thereby causing the long-side surface of the battery cell to be processed to be in contact with the two long-side rollers 934 for moving roller pressing.
