[0002] The capacitor foil strip welding mechanism is an important equipment specially used in capacitor manufacturing, which is used to ensure the reliable connection of the capacitor foil strip. This mechanism realizes the precise welding of the capacitor foil strip by combining the lifting cylinder, welding seat, spot welding rod and control system. In this mechanism, the welding chassis is used as the main structure, and the lifting cylinder and welding seat are arranged inside. The lifting cylinder controls the up and down movement of the welding seat through the cylinder shaft so that the welding head can accurately contact the capacitor foil strip. During the welding process, the pressure supply mechanism is activated by the foot-operated welding switch, and the lifting cylinder is pressurized to drive the welding seat down, so that the spot welding head contacts the foil strip to form a welding path. The display screen and control buttons provide adjustment of welding power and parameters to ensure welding quality and stability.

[0003] However, when the capacitor foil strip welding mechanism is in use, it is necessary to place the capacitor foil strip on the fixed spot welding head, and then control the lifting spot welding head to descend and contact the welding position, so that the welding process of the capacitor foil strip will be completed by the fixed spot welding head and the lifting spot welding head. When the capacitor foil strips need to be welded in batches, the storage rack for storing the capacitor foil strips and the storage rack need to be placed on one side of the welding mechanism.

After the welding process, the capacitor foil strip needs to be moved by the user again and placed on the storage rack. This operation method is not only time-consuming and laborious, but also greatly reduces the welding efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The display screen 14 can display information such as the power of the spot welding head during welding, so that the user can adjust the welding power through the control button 13, so that the capacitor foil strip welding mechanism can weld capacitor foil strips of various materials, and a base 1 is arranged at the bottom of the welding chassis 4. A foot-operated welding switch 2 is arranged at the front side of the top center of the base 1. After the foot-operated welding switch 2 is stepped on, the pressure supply mechanism inside the welding chassis 4 will be started, and the pressure supply mechanism will pressurize the lifting cylinder 9, so that the lifting cylinder 9 drives the lifting welding seat 8 to descend through the cylinder shaft 12, so that the lifting spot welding head can contact the capacitor foil strip, so as to complete the welding process of the capacitor foil strip.

[0022] like Figure 1 and Figure 2As shown, when the capacitor foil strip welding mechanism is used, the control power supply needs to be connected to the welding chassis 4, and the lifting cylinder 9 needs to be connected to the pressure supply mechanism inside the welding chassis 4 through the air pipe, so that the pressure supply mechanism can pressurize or relieve the pressure inside the lifting cylinder 9. When the capacitor foil strip needs to be welded, the welding parts of the capacitor foil strip to be welded are attached to each other and placed on the top of the fixed spot welding rod 6 at the front end of the fixed welding seat 5. Then the user needs to step on the foot-operated welding switch 2 with his foot. After the foot-operated welding switch 2 is stepped on, the pressure supply mechanism inside the welding chassis 4 will pressurize the inside of the lifting cylinder 9 The lifting cylinder 9 pushes down the lifting welding seat 8 through the cylinder shaft 12. The lifting welding seat 8 will make the lifting spot welding head contact the upper end of the capacitor foil strip, so that a welding path will be formed. At this time, the lifting spot welding head will complete the welding process of the capacitor foil strip by spot welding. After the welding is completed, the stepped foot welding switch 2 is released. At this time, the pressure supply mechanism inside the welding chassis 4 will relieve the pressure inside the lifting cylinder 9, so that the cylinder shaft 12 drives the lifting welding seat 8 to move upward to the original position, and then the new capacitor foil strip that needs to be welded can be welded according to the above steps.

[0023] like Figure 1 and Figure 3 As shown, a temporary storage device 3 is provided at the lower side of the fixed welding seat 5, and the temporary storage device 3 includes a lifting rod 15, a lifting sleeve A16, a lifting sleeve B19, a hand-tightened screw 20 and a horizontal support rod 21. The lifting sleeves A16 and B19 are respectively fixed at the left and right ends of the welding chassis 4 and located at the front end outer wall. The lifting sleeves A16 and B19 are both located at the lower side of the fixed welding seat 5. The lifting sleeves A16 and B19 are both threadedly inserted with hand-tightened screws 20 on the upper side of the front center. The lifting sleeves A16 and B19 are both inserted with lifting rods 15. The top front ends of the two lifting rods 15 are both provided with horizontal support rods. Rod 21, when the hand-tightening screw 20 is loosened, the rear end of the screw rod does not contact the front end outer wall of the lifting rod 15, and the lifting rod 15 can move up and down in the lifting sleeve A16 and the lifting sleeve B19. After the hand-tightening screw 20 is tightened, the rear end of the screw rod tightly contacts and squeezes the front end outer wall of the lifting rod 15. The temporary storage device 3 also includes a storage tray 17 and a U-shaped baffle frame 18. The storage tray 17 is fixed to the upper end of the front half of the two horizontal support rods 21. The left and right ends and the front end top of the storage tray 17 are connected with the U-shaped baffle frame 18. The storage tray 17 is made of aluminum alloy, and the rear end outer wall of the storage tray 17 is located on the front side of the front end outer wall of the fixed welding seat 5.

[0024] like Figure 1 and Figure 3As shown, when it is necessary to weld capacitor foil strips in batches, the temporary storage device 3 can be adjusted to be at an optimal height, and then a large number of capacitor foil strips can be placed on the storage tray 17 of the device, so that the user can accurately and quickly pick up the capacitor foil strips for welding. When operating the temporary storage device 3, it is necessary to hold the storage tray 17, and then loosen the hand screws 20 on the lifting sleeve A16 and the lifting sleeve B19. After the hand screws 20 are loosened, the locking effect on the lifting rod 15 will be lost, and then the storage tray 17 will be pushed upward. At this time, the lifting rod 15 will move upward in the lifting sleeve A16 and the lifting sleeve B19, which will cause the storage tray 17 originally located at the lower side of the front end of the fixed welding seat 5 to move upward until the storage tray 17 is at the optimal operating height, such as the storage tray 17. When the tray 17 is located at the front side of the front end of the fixed welding seat 5, it is necessary to maintain the height and retighten the hand-tightened screw 20. After the hand-tightened screw 20 is tightened, the screw rod will tightly contact the front end of the lifting rod 15, so that the lifting rod 15 inside the lifting sleeve A16 and the lifting sleeve B19 can be height-fixed. In this way, the storage tray 17 will be locked at the currently adjusted height. Then, just place the capacitor foil strips to be welded on the storage tray 17. Then, during the welding process, the user only needs to pick up a group of capacitor foil strips and perform welding through the fixed spot welding rod 6 and the lifting spot welding rod 7. After welding, the capacitor foil strips can be placed back on the top of the left end of the storage tray 17. This can make the welding operation simpler and faster and also increase the welding efficiency.
