Description

A lead-acid battery casting and welding equipment Technical Field

[0001] This utility model relates to the field of lead-acid battery production technology, specifically to a lead-acid battery casting and welding equipment. Background Technology

[0002] Casting and welding equipment, also known as fully automatic battery casting and welding machine, consists of fixtures, molds, furnaces, and cooling devices. Lead-acid batteries are composed of important components such as plastic shells (usually made of ABS or PP materials), electrode groups (composed of positive plates, negative plates, busbars, and separators), and busbars. The tabs and busbars are formed by casting and welding, and the tabs are also connected to the busbars at the top.

[0003] The patent document with publication number CN217964721U discloses a casting and welding fixture for lead-acid batteries that is easy to calibrate. The fixture clamps the electrode group and then performs casting and welding. This production method involves casting and welding the electrode group first and then placing it into the tank. When the welded electrode group is clamped into the tank, the welding position of the electrode tab is prone to breakage, resulting in a high defect rate of the battery.

[0004] Patent document CN211331271U discloses a casting welding tank for lead-acid battery electrode casting. When cooling of the casting cavity is required, coolant is injected into the cooling pipe through the input pipe. The coolant absorbs the heat of the molten lead on the mold plate, causing it to cool and solidify rapidly. This casting welding tank is generally used when casting welding is performed after the electrode group is inserted into the battery casing. However, the casting welding equipment using this tank has low production efficiency because the coolant inside the tank needs to be heated when it enters the tank, resulting in low heating efficiency. Simultaneously, the equipment for cooling the coolant in the cooling pipes experiences heavy workload due to the frequent high-temperature heating of the coolant. Summary of the Invention

[0005] The main objective of this invention is to provide a lead-acid battery casting and welding equipment that can improve casting and welding efficiency.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A lead-acid battery casting and welding equipment includes a battery clamping assembly. A base plate is provided below the battery clamping assembly, and a lead pot is fixed to the upper part of the base plate. A vertical lower cylinder is fixed to the base plate on one side of the lead pot. An inverted L-shaped connecting rod is fixed to the telescopic end of the lower cylinder. A casting and welding mold is fixed to the connecting rod. A bracket is fixed to the base plate on the other side of the lead pot. A motor is fixed to the upper end of the bracket. A rotating rod is concentrically fixed to the output shaft of the motor. A scraper is fixed to the upper end of the rotating rod. A fixing plate is fixed to one side of the rotating rod. A connecting plate is slidably arranged on the rotating rod below the fixing plate. The fixing plate and the connecting plate are connected by a vertical lifting cylinder. A cooling plate is fixed to the connecting plate.

[0008] Specifically, the cooling plate has a serpentine cooling channel, and an inlet pipe and an outlet pipe are fixed on the cooling plate. The inlet pipe and the outlet pipe are respectively connected to the two ends of the cooling channel, and the cooling equipment is connected to the inlet pipe and the outlet pipe through a flexible hose.

[0009] Specifically, the battery clamping assembly includes an upper plate, a lifting frame parallel to the upper plate is provided below the upper plate, the lifting frame is connected to the upper plate by multiple vertical upper cylinders, multiple clamping cavities are provided inside the lifting frame, a clamping cylinder is fixed on the lifting frame on the rear side of the clamping cavity, and a clamping plate is fixed on the telescopic end of the clamping cylinder.

[0010] Specifically, the rotating rod is a square rod.

[0011] Specifically, the lifting frame is set up vertically and vertically corresponding to the casting and welding mold.

[0012] Specifically, the scraper and the cooling plate are offset in their rotational direction.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. Utilizing a motor-driven scraper and cooling plate linkage structure, the scraper removes excess molten lead from the mold surface in real time, while the staggered cooling plate immediately provides directional cooling to the casting mold, significantly shortening the production cycle. The cooling plate is circulated with external cooling equipment via a serpentine cooling channel, avoiding the problem of overall heating in traditional casting baths and improving cooling efficiency.

[0015] 2. The cooling plate and the casting mold adopt a separate contact cooling design, breaking through the traditional overall heating mode. By controlling the lifting cylinder to selectively contact the cooling plate with the bottom of the mold, the temperature field of the lead pot is kept stable while ensuring rapid solidification, reducing energy consumption, and avoiding energy waste caused by repeated heating of the coolant.

[0016] 3. The battery clamping assembly is equipped with a multi-cylinder linkage system. The upper cylinder controls the alignment of the lifting frame with the casting and welding mold, while the clamping cylinder achieves precise battery positioning. This structure allows the tabs to be accurately inserted into the mold grooves of the casting and welding mold.

[0017] 4. The combination of the rotating rod, the staggered scraper, and the cooling plate creates a spatial synergy effect, allowing a single motor to complete the timing control of both scraping and cooling processes. Compared to traditional multi-motor drive solutions, this reduces the number of transmission components, lowers the equipment failure rate, and significantly reduces maintenance costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Referring to Figures 1-4, a lead-acid battery casting and welding equipment includes a battery clamping assembly. A base plate 8 is positioned below the battery clamping assembly. A lead pot 19 is fixed to the upper end of the base plate 8. A vertical lower cylinder 9 is fixed to one side of the base plate 8 of the lead pot 19. An inverted L-shaped connecting rod 10 is fixed to the telescopic end of the lower cylinder 9. A casting and welding mold 11 is fixed to the connecting rod 10. A bracket 12 is fixed to the other side of the base plate 8 of the lead pot 19. A motor 13 is fixed to the upper end of the bracket 12. A rotating rod 14 is concentrically fixed to the output shaft of the motor 13. The rotating rod 14 is a square rod. A scraper 18 is fixed to the upper end of the rotating rod 14. A fixing plate 17 is fixed to one side of the rotating rod 14. A connecting plate 20 is slidably mounted on the rotating rod 14 below the fixing plate 17. The fixing plate 17 and the connecting plate 20 are connected by a vertical lifting cylinder 16. A cooling plate 15 is fixed to the connecting plate 20. When the rotating rod 14 rotates, the scraper 18 and the cooling plate 15 rotate accordingly.

[0025] The cooling plate 15 has a serpentine cooling channel 21. An inlet pipe 22 and an outlet pipe 23 are fixed on the cooling plate 15. The inlet pipe 22 and the outlet pipe 23 are respectively connected to the two ends of the cooling channel 21. The cooling equipment is connected to the inlet pipe 22 and the outlet pipe 23 through flexible hoses.

[0026] The battery clamping assembly includes an upper plate 1, with a lifting frame 3 parallel to it located below the upper plate 1. The lifting frame 3 is vertically aligned with the casting and welding mold 11. The lifting frame 3 is connected to the upper plate 1 by multiple vertical upper cylinders 2. The lifting frame 3 has multiple clamping cavities 7. A clamping cylinder 5 is fixed to the lifting frame 3 on the rear side of the clamping cavity 7. A clamping plate 6 is fixed to the telescopic end of the clamping cylinder 5.

[0027] When the tabs of the inner electrode group of battery 4 are cast and welded, the battery 4 is placed in the clamping cavity 7 after being inverted and kept at the same height. The clamping cylinder 5 is activated, and the clamping plate 6 is used to press against the battery 4, so that the battery 4 is fixed in the clamping cavity 7.

[0028] The casting mold 11 is heated inside the lead pot 19. The lower cylinder 9 is activated, causing the casting mold 11 to rise within the lead pot 19 via the connecting rod 10. Once the casting mold 11 is in position, it is above the lead pot 19. Then, the motor 13 is activated, driving the rotating rod 14 to rotate. As the rotating rod 14 rotates, the scraper 18 rotates. When the lower end of the scraper 18 contacts the upper end of the casting mold 11, it scrapes away excess molten lead. The scraped lead flows back into the lead pot 19. After the scraper 18 is misaligned with the casting mold 11, the upper cylinder 2 is activated, causing the lifting frame 3 and battery 4 to descend. The tabs of the battery 4 contact the molten lead in the mold groove at the upper end of the casting mold 11. Then, motor 13 is started, driving the rotating rod 14 to rotate, which in turn causes the scraper 18 and cooling plate 15 to continue rotating. When the cooling plate 15 is below the casting mold 11, motor 13 is turned off, and lifting cylinder 16 is started. After the cooling plate 15 contacts the casting mold 11, it cools the casting mold 11. The molten lead in the upper mold groove of the casting mold 11 cools and solidifies, connecting with the electrode tabs of the electrode plates to form a busbar. The upper cylinder 2 is started, causing the lifting frame 3 and battery 4 to move upward, and the busbar separates from the casting mold 11.

[0029] After battery 4 moves upward, lifting cylinder 16 is activated, causing cooling plate 15 to move downward and return to its original position. Motor 13 is then activated, and motor 13, through rotating rod 14 and connecting plate 20, causes scraper 18 and cooling plate 15 to rotate and reset. Then, lower cylinder 9, through connecting rod 10, causes casting mold 11 to move downward and enter lead pot 19 for reheating.

[0030] The upper plate 1 can be connected to a robotic arm, which will move the upper plate 1, upper cylinder 2, lifting frame 3, and the cast and welded battery 4 to the unloading station.

[0031] Example 2: Based on Example 1, referring to Figure 3, the scraper 18 and the cooling plate 15 are offset in their rotational direction. After the scraper 18 scrapes off the excess lead liquid at the upper end of the casting and welding mold 11, the cooling plate 15 is located below the casting and welding mold 11.

[0032] In this embodiment, after the scraper 18 scrapes away the excess lead liquid at the upper end of the casting and welding mold 11, the scraper 18 is misaligned with the casting and welding mold 11. At this time, the cooling plate 15 is located below the casting and welding mold 11. When cooling the casting and welding mold 11, the lifting cylinder 16 can be directly activated to make the cooling plate 15 contact the lower end of the casting and welding mold 11 for cooling, which can improve the casting and welding efficiency of the battery 4.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
