For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components.

[0043] like Figure 1-5 As shown, a flipping platform for battery box welding equipment includes: a conveyor belt 1, an automatic welding machine 2, a placement platform 3, a guardrail 4, a layered plate 5, a lifting cylinder 6, a transmission rod 7, a first mounting frame 8, a steering collar 9, a dial 10, a steering link 11, a dial member 12, and a second mounting frame 13. The conveyor belt 1 is horizontally erected on the ground, the automatic welding machine 2 is installed on the conveyor belt 1, and the placement platform 3 is located on one side of the conveyor belt 1, providing a basic platform for placing the battery shell 16. During the welding process, the battery shell 16 is placed on the cross support 15 on the placement platform 3, and the platform provides a stable support structure for the entire flipping operation. The guardrail 4 is horizontally erected on an edge of the placement platform 3 to play a protective and limiting role. The guardrail 4 can prevent the battery shell 16 from sliding off the platform, ensuring the safety of the operation. The layer plate 5 is installed on the support frame of the placement platform 3. The layer plate 5 divides the support frame of the placement platform 3 into two layers, the upper and lower parts. The lifting cylinder 6 is installed below the layer plate 5. The output end of the lifting cylinder 6 is passed through the layer plate 5, and the transmission rod 7 is installed at the output end of the lifting cylinder 6.

[0044] In this embodiment, the top end of the transmission rod 7 is inserted into the placement platform 3. The first mounting bracket 8 is sleeved onto the shaft of the transmission rod 7. The steering collar 9 is sleeved onto the shaft of the transmission rod 7. At least four shifting openings 10 are provided on the side surfaces of the steering collar 9. The steering collar 9 cooperates with the transmission rod 7, and the shifting openings 10 are provided on the side surfaces of the steering collar 9. The shifting openings 10 provide a point of action for a shifting member 12. When the shifting member 12 is driven by the steering link 11 to shift between the shifting openings 10, it can pull the transmission rod 7 axially to rotate, thereby achieving a 90-degree flip of the battery housing 16. This is key to achieving precise angled flipping of the battery housing 16. One end of the steering link 11 is sleeved onto the shaft of the transmission rod 7, and the shifting member 12 is mounted on the steering link 11. One end of the shifting member 12 is inserted into any of the shifting openings 10, acting as a component that directly acts on the shifting openings 10 of the steering collar 9. Driven by the steering link 11, the toggle member 12 is inserted into the different toggle openings 10, and by pulling the transmission rod 7, the battery housing 16 is rotated axially, thus acting as the actuator for flipping the battery housing 16. The second mounting bracket 13 is mounted to one side of the first mounting bracket 8, and the steering cylinder 14 is mounted on the second mounting bracket 13. The output end of the steering cylinder 14 is movably connected to the other end of the steering link 11.

[0045] Preferably, the cross support 15 is passed through the placement platform 3, the cross support 15 is installed on the top of the transmission rod 7, the battery housing 16 is placed on the cross support 15, and the stop ring 17 is located above the ring. The cross support 15 serves as a direct placement component for the battery housing 16. Its cross-shaped design can provide stable support for the battery housing 16, ensuring that the battery housing 16 will not be displaced during welding and flipping operations, and can move synchronously with the lifting and rotation of the transmission rod 7. At least four stop holes 18 are opened on the side wheel surface of the stop ring 17; the opening position of each stop hole 18 is located directly above each dial port 10. The hole depth of the stop hole 18 extends all the way to the rod body of the transmission rod 7, and the output end of the stop cylinder 19 is passed through the first mounting bracket 8, and the output end of the stop cylinder 19 is passed through any stop hole 18. The stop hole 18 on the stop ring 17 cooperates with the stop cylinder 19. When the battery housing 16 is turned over, the output end of the stop cylinder 19 passes through the stop hole 18 and presses against the rod body of the transmission rod 7, thereby temporarily fixing the transmission rod 7 to prevent the transmission rod 7 from accidentally rotating when the steering cylinder 14 drives the steering link 11 and the toggle member 12 to move, thereby ensuring the accuracy of the operation.

[0046] It should be noted that the flip platform of a battery box welding equipment designed by the present invention, when in use, the automatic welding machine 2 starts to weld the bottom seam of the battery box shell, once the seam on one side of the battery shell 16 is welded, the lifting cylinder 6 can be started, the output end of the lifting cylinder 6 pops out to push the transmission rod 7 to lift, the transmission rod 7 lifts the cross support 15 on the top, and after it is higher than the guardrail 4 on the side, it is ensured that there is no obstruction. At this time, the steering cylinder 14 and the cut-off cylinder 19 are started, the output end of the cut-off cylinder 19 passes through the cut-off hole 18 and abuts against the rod body of the transmission rod 7, making it unable to rotate, the output end of the steering cylinder 14 pops out to drive the steering connecting rod 11, the steering connecting rod 11 performs an angular rotation to drive the toggle 12 on it to start rotating around the steering collar 9, after the toggle 12 arrives at the next toggle 10, the retraction cylinder, at this time retracts the output end of the cut-off cylinder 19, and the transmission rod 7 loses the force. The output end of the steering cylinder 14 retracts, causing the toggle 12 to rotate. The toggle 12 hooks onto the next toggle 10, pulling the transmission rod 7 axially. Because each toggle 10 has a 90-degree angle, the transmission rod 7 rotates 90 degrees, causing the battery housing 16 on the transmission rod 7 to flip and rotate 90 degrees. At this point, the lifting cylinder 6 retracts, lowering the cross support 15 to the placement platform 3, and welding can begin on the next side. This process is repeated in this way, completing all welding operations around the bottom of the battery box housing. The entire process does not require manual side switching.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
