Description

Technical Field

[0001] This invention relates to the field of casting and welding machine technology, and more particularly to a circular intermittent casting and welding machine. Background Technology

[0002] The structure of a lead-acid battery mainly consists of a casing and internal components such as positive and negative plates, separators, and electrolyte. Within the same lead-acid battery, the tabs of the plates are connected together by a busbar formed through a casting and welding process. The casting and welding of battery components is generally carried out in an assembly line manner. The process typically involves pouring molten lead into a busbar mold at the lead injection station to form the mold, then placing the lead-acid battery upside down on the mold for casting and welding. After the molten lead has cooled sufficiently, it forms a busbar that connects the tabs of the plates. Finally, the cast-welded lead-acid battery is shipped out for subsequent assembly of other components and electrolyte filling.

[0003] Traditional lead-acid battery casting and welding production lines are usually linear conveyor structures. Although they can achieve automated casting and welding production between lead-acid battery electrode groups, they generally suffer from problems such as large size, large space occupation, and slow workstation changeover.

[0021] The advantages or beneficial effects of the above technical solution include at least the following: During the casting and welding of lead-acid battery electrode groups, after the cutting and brushing operation of the cutting brush device and the flux application of the flux coating device, the lead-acid battery electrode groups coated with flux are transported to the support plate above the lead-casting furnace. Then, through the cooperation of the circular turntable mechanism of the multi-station circular rotating mold opening and closing device, multiple casting and welding mechanisms, and the mold opening and closing mechanism, the circular intermittent rotation and mold opening and closing operations are achieved. With the radiant heating device on one side of the lead-casting furnace, the passing casting mold can be preheated to prevent solidification in the casting mold, which would affect the fluidity of the molten lead. After the molten lead is injected through the lead-casting furnace, it is then heated by the radiant heating device on the other side. The heating device reheats the casting mold and molten lead to ensure the fluidity of the molten lead and the casting effect. Then, the lead-acid battery electrode group on the support plate is moved into the casting mold by the mold closing assembly to come into contact with the molten lead for casting. During this process, the casting mold and molten lead are cooled by air blowing by the cooling device to facilitate the cooling and solidification of the molten lead and complete the casting. After casting, the lead-acid battery electrode group is demolded by the mold opening assembly, and then the casting and conveying device is used to remove the cast-welded lead-acid battery electrode group for subsequent casting operations. This allows the casting and welding of lead-acid batteries to achieve automatic intermittent continuous mold opening and closing and casting, thereby reducing production time, reducing space occupation, and improving the casting and welding efficiency of lead-acid batteries.

Multiple casting and welding mechanisms 22 are arranged around the circular turntable mechanism 21, and the mold opening and closing mechanism 23 is installed at the center of the main frame 1 corresponding to the circular turntable mechanism 21.

[0071] The circular turntable mechanism 21 can employ a combination of a worm gear and a worm shaft, and be equipped with a motor to drive the worm shaft, so that the worm gear rotates to drive the turntable to rotate.

[0072] The casting and welding mechanism 22 includes a casting and welding support 221, a casting and welding lifting seat 222 vertically slidably connected to the casting and welding support 221, a support plate 223 for supporting the lead-acid battery electrode group on the casting and welding lifting seat 222, a positioning rod 224 slidably connected to the casting and welding lifting seat 222 on the top of the casting and welding support 221, a positioning push plate 2241 on the side of the positioning rod 224 away from the casting and welding lifting seat 222, a positioning hole 2221 passing through the casting and welding lifting seat 222 corresponding to the position of the positioning rod 224, the positioning hole 2221 being adapted to the positioning rod 224, a casting and welding mold 225 being provided at the bottom of the casting and welding support 221, a lifting sliding hole 2211 being provided on the casting and welding support 221, and a lifting support rod 2222 passing through the lifting sliding hole 2211 being provided on the casting and welding lifting seat 222.

[0073] The mold opening and closing mechanism 23 includes a mold opening and closing bracket 231. A mold closing assembly 232 and a mold opening assembly 233 are mounted on the mold opening and closing bracket 231. The mold closing assembly 232 includes a mold closing cylinder 2321 mounted on the top of the mold opening and closing bracket 231. A mold closing support plate 2322 is mounted on the output end of the mold closing cylinder 2321. The mold closing support plate 2322 is slidably connected to the mold opening and closing bracket 231. A pull plate 2324 driven by the first positioning cylinder 2323 is mounted on the mold closing support plate 2322. The pull plate 2324 is used to pull the positioning push plate 2241, causing the positioning rod 224 to disengage from the positioning hole 2. 221, The mold opening assembly 233 includes a mold opening cylinder 2331 installed on the top of the mold opening and closing bracket 231. The output end of the mold opening cylinder 2331 is provided with a mold opening support plate 2332. The mold opening support plate 2332 is slidably connected to the mold opening and closing bracket 231. The mold opening support plate 2332 is provided with a push plate 2334 driven by the second positioning cylinder 2333. The push plate 2334 is used to push the positioning push plate 2241 so that the positioning rod 224 is embedded in the positioning hole 2221. The mold closing support plate 2322 and the mold opening support plate 2332 are both used to support the lifting support rod 2222 on the corresponding work station.

[0074] The mold closing assembly 232 and the mold opening assembly 233 are arranged opposite to each other. The mold opening assembly 233 is positioned facing the material discharge and conveying device 7. When the casting and welding mechanism 22 rotates to the mold closing assembly 232 via the circular turntable mechanism 21, the pull plate 2324 driven by the first positioning cylinder 2323 of the mold closing assembly 232 pulls the positioning push plate 2241 on the casting and welding mechanism 22. The positioning push plate 2241 then drives the positioning rod 224 to disengage from the positioning hole 2221. The lifting support rod 2222 is supported by the mold closing support plate 2322. The mold closing cylinder 2321 drives the mold closing support plate 2322 to move downward, causing the mold closing support plate 2322 to move the lifting support rod 2222, the casting and welding lifting seat 222, and the bearing plate 223 downward. This moves the tabs of the lead-acid battery electrode group on the bearing plate 223 to the casting and welding mold 225 for casting and welding. When mechanism 22 rotates to mold closing assembly 232 via rotary table mechanism 21, the lifting support rod 2222 of casting and welding mechanism 22 rotates onto mold opening support plate 2332 of mold opening assembly 233. Then, the mold opening cylinder 2331 of mold opening assembly 233 drives the mold opening support plate 2332 to rise, causing the mold opening support plate 2332 to move the lifting support rod 2222, casting and welding lifting seat 222, and bearing plate 223 upwards, thereby placing the cast and welded lead-acid battery electrode group... After demolding, the push plate 2334 driven by the second positioning cylinder 2333 pushes the positioning push plate 2241, so that the positioning push plate 2241 drives the positioning rod 224 to be embedded in the positioning hole 2221, so as to position the casting and welding lifting seat 222 on the top of the casting and welding support 221, thereby facilitating the transportation of the cast and welded lead-acid battery electrode group through the discharge and conveying device 7, and making the casting and welding mold 225 convenient for preheating of the radiation heating device 5 and lead injection of the lead injection furnace 4.

[0075] Using the above structure, during the casting and welding of lead-acid battery electrode groups, after the cutting and brushing operation of the cutting brush device 8 and the flux application of the flux application device 6, the flux-coated lead-acid battery electrode groups are transported by the flux application device 6 to the support plate 223 above the lead-filling furnace 4. Multiple casting and welding mechanisms 22 are fixed on the circular turntable mechanism 21, and driven by the circular turntable mechanism 21, the multiple casting and welding mechanisms 22 can be intermittently driven to rotate in a circular motion. This allows the multiple casting and welding mechanisms 22 to move intermittently in a circular motion along the circular turntable mechanism 21. With the radiant heating device 5 installed on one side of the lead-filling furnace 4, the passing casting and welding mold 225 can be preheated to prevent solidification of the lead liquid poured into the casting and welding mold 225 by the lead-filling furnace 4, which would affect the fluidity of the lead liquid. Then, the lead liquid is poured into the lead-filling furnace 4... After the lead liquid is poured in, the casting mold 225 and the lead liquid are reheated by the radiation heating device 5 on the other side to ensure the fluidity of the lead liquid and the casting effect. Then, the lead-acid battery electrode group on the support plate 223 is moved into the casting mold 225 by the mold closing assembly 232 to contact the lead liquid for casting. During this period, the casting mold 225 and the lead liquid are cooled by air blowing by the cooling device 3 to facilitate the cooling and solidification of the lead liquid and complete the casting. After casting, the lead-acid battery electrode group is demolded by the mold opening assembly 233. Then, with the help of the material unloading and conveying device 7, the cast and welded lead-acid battery electrode group is moved out for subsequent casting operations. This enables the casting and welding of lead-acid batteries to achieve automatic intermittent continuous mold opening and closing and casting, thereby reducing production time, reducing space occupation, and improving the casting and welding efficiency of lead-acid batteries.

[0076] In one embodiment, see Figure 4 In order to limit the movement of the positioning push plate 2241, a limit frame 226 is provided on the top of the cast and welded support 221. The limit frame 226 is provided with a limit slot 2261. The positioning push plate 2241 is located in the limit slot 2261. Buffer columns 2262 are provided on both sides of the limit frame 226 corresponding to the positioning push plate 2241.

[0077] In one embodiment, see Figure 4 and Figure 7 To facilitate the cooling and shaping of the molten lead during casting and welding, the casting mold 225 is provided with ventilation holes 2251. The cooling device 3 includes a ventilation pipe 31, with a filter screen 32 at one end of the ventilation pipe 31 facing the ventilation hole 2251 and a fan 33 at the other end, directing the air generated by the fan 33 to the ventilation hole 2251.
