Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery casting and welding technology, specifically relating to an infrared heating lead-acid battery casting and welding device. Background Technology

[0002] In recent years, with the rapid development of the new energy industry, the diversification of products, and increasingly fierce market competition, the lead-acid battery industry must make technological innovation in production line processes and equipment to achieve comprehensive performance in energy saving, consumption reduction, quality improvement, and cost reduction.

[0003] Battery casting and welding on the assembly line is a crucial step in battery manufacturing. The existing Xiaomi assembly line is equipped with six casting and welding machines, with a single line capacity of 12,000 units per day. The casting and welding machines are lead pot hot mold casting and welding machines, and each machine is equipped with a separate pot. The mold is heated by immersing the mold in molten lead, resulting in high energy consumption, high lead fume emissions, high lead slag rate, and low raw material utilization rate.

[0004] For example, the invention disclosed in CN111069573A is a battery casting and welding device, which includes a translation plate. The translation plate is provided with a first scraper and a second scraper. The second scraper is vertically and vertically disposed below the translation plate. When the casting and welding bottom mold is immersed in the lead liquid in the lead pot, the second scraper descends and moves horizontally with the translation plate to scrape the scum on the surface of the lead liquid to one side, and resets before the casting and welding bottom mold is raised above the lead pot.

[0005] For example, the invention with publication number CNv12222379A discloses a lead-acid battery casting and welding machine and its casting and welding method. In this invention, the inlet driving mechanism is set below the lifting driving mechanism for moving the battery electrode group, the flipping mechanism is set on one side of the inlet driving mechanism for flipping the battery electrode group, the ejector driving mechanism is set on the other side of the inlet driving mechanism for clamping the battery electrode group, and the casting and welding mold is set below the inlet driving mechanism and driven by the lifting driving mechanism. The lifting driving mechanism, the inlet driving mechanism, and the ejector driving mechanism are connected by a support mechanism, which is set on the lead pot. Utility Model Content

[0006] This invention addresses the aforementioned shortcomings in the existing technology by providing an infrared heating lead-acid battery casting and welding device, which solves the problems of excessive lead fumes, high energy consumption, and low raw material utilization during the casting and welding process.

[0007] An infrared heating lead-acid battery casting and welding device, used in conjunction with a casting and welding bottom mold, wherein the top surface of the casting and welding bottom mold has a casting and welding cavity, the infrared heating lead-acid battery casting and welding device comprising:

[0008] A support frame, on which an infrared heating station and a casting and welding station are sequentially provided;

[0009] A lead liquid adding mechanism is located at one end of the infrared heating station near the casting and welding station, and is used to add lead liquid into the casting and welding cavity. The lead liquid adding mechanism includes a lead liquid tank, the bottom surface of which is provided with an adding hole for adding lead liquid into the casting and welding cavity. The lead liquid adding mechanism also includes a lead wire supply unit and a hot melting unit for melting and heating the lead wire into lead liquid. The lead liquid formed after the lead wire is melted enters the lead liquid tank.

[0010] An infrared heating mechanism is located at the infrared heating station and is used to heat the casting and welding bottom mold and the lead liquid tank.

[0011] A casting and welding mechanism, located at the casting and welding station, is used to insert the tabs on the inverted lead-acid battery into the casting and welding cavity and cast and weld them to form a busbar and terminal posts.

[0012] The transfer mechanism is used to transfer the casting and welding bottom mold between various work stations.

[0013] Preferably, the infrared heating mechanism includes two rows of infrared heating tubes, with a gap between the two rows of infrared heating tubes for the casting and welding bottom mold to pass through. The two rows of infrared heating tubes form a symmetrical heating structure, allowing the casting and welding bottom mold to pass through the gap, thereby achieving surround heating, eliminating the temperature difference problem of traditional local heating, ensuring the uniformity of the temperature of the casting and welding bottom mold, and achieving high temperature control accuracy.

[0014] Preferably, the bottom mold for casting and welding is provided with support blocks on both sides, and the support blocks are provided with sliding grooves;

[0015] The transfer mechanism includes: a first slide rail, located on both sides of the infrared heating station and the casting and welding station, wherein the casting and welding bottom mold slides with the first slide rail through a groove on the support block; a first drive unit, used to drive the casting and welding bottom mold to move along the first slide rail; and a robotic arm, used to transfer the casting and welding bottom mold located at the casting and welding station after completing one casting and welding operation back to the upstream end of the infrared heating station.

[0016] Furthermore, the robotic arm includes: a second slide rail disposed above the infrared heating station and the casting and welding station; a robotic arm base having a groove that mates with the second slide rail, the robotic arm base also having a lifting arm and a lifting drive unit for driving the lifting arm to move up and down, the bottom of the lifting arm having a pair of horizontally moving grippers and a cylinder for driving the horizontally moving grippers to grip or release the casting and welding bottom mold; and a second drive unit for driving the robotic arm base to move along the second slide rail.

[0017] Furthermore, in use, the casting and welding bottom mold comprises multiple pieces arranged in sequence;

[0018] The first driving unit includes a push plate for pushing the casting and welding bottom mold located upstream of the infrared heating station downstream, and the bracket is provided with a push plate driving cylinder for driving the push plate.

[0019] The second drive unit includes a second linear rack arranged parallel to the second slide rail; the second drive unit also includes a second gear meshing with the second linear rack, and the robot base is provided with a second gear drive motor that drives the second gear to rotate.

[0020] Furthermore, it also includes a pick-and-place mechanism for picking up and placing lead-acid batteries at the casting and welding station. The pick-and-place mechanism includes a pick-and-place base with a groove that cooperates with the second slide rail. The pick-and-place base is also provided with a horizontal mounting bracket that can move along a direction perpendicular to the second slide rail. The horizontal mounting bracket is provided with a vertical mounting bracket that can move vertically. The vertical mounting bracket is provided with a clamping unit for clamping the lead-acid batteries. The vertical mounting bracket is also provided with a flipping unit for driving the clamping unit to flip up and down.

[0021] The entire transfer process is automated: mold preheating → quantitative lead injection → electrode tab casting and welding → water cooling → mold removal → cleaning – all without human intervention. This reduces human error, stabilizes product quality, and frees up manpower, reducing labor costs.

[0022] The cylinder pusher mold enables rapid switching between workstations; the robotic arms have clearly defined roles (picking, placing, flipping, and transferring batteries and molds). Modular and efficient collaboration supports an ultra-short production cycle of 15-20 seconds, achieving high single-line capacity (one-outlet eight-mold design, 12,000-14,000 units / shift).

[0023] Preferably, the lead liquid tank has an opening at the top, and a cover plate is provided at the opening. The cover plate is provided with a lead liquid hot melting tank, and the bottom surface of the lead liquid hot melting tank has a lead liquid inlet that communicates with the lead liquid tank.

[0024] The lead wire supply unit includes a lead wire limiting tube for the lead wire to pass through and a lead wire driving component for driving the lead wire forward. The outlet end of the lead wire limiting tube is located in the lead melt hot melting tank.

[0025] The hot-melt unit includes a hot-melt nozzle corresponding to the outlet end of the lead wire limiting tube.

[0026] Enclosed lead wire melting (hot melt nozzle + cover plate) replaces open lead melting furnaces, greatly reducing lead vapor escape. This achieves cleaner production, protects worker health, and reduces environmental treatment costs.

[0027] In addition, the lead wire drive unit can use a servo motor to precisely feed the lead wire, melting it according to the actual lead required for each battery bus. This avoids the waste of leftover material in traditional casting and significantly reduces lead consumption.

[0028] Furthermore, the lead liquid adding mechanism also includes a switch for controlling the opening and closing of the adding hole on the bottom surface of the lead liquid tank. The switch is a switch cylinder provided on the cover plate. When the piston rod of the switch cylinder extends, its end blocks the adding hole.

[0029] The lead liquid adding mechanism also includes at least two temperature sensors, one of which is used to detect the temperature of the lead liquid tank, and the other is used to detect the temperature of the lead liquid inside the lead liquid tank.

[0030] Preferably, the casting and welding mechanism includes:

[0031] A cooling tank is located on the side of the casting and welding station near the lead liquid adding mechanism. The top surface of the cooling tank is open, and when cooling the bottom mold of the casting and welding, the top surface opening of the cooling tank is directly opposite the bottom surface of the bottom mold of the casting and welding. The cooling tank is equipped with a cooling component for cooling the bottom mold of the casting and welding. The cooling component of this utility model adopts a cooling pipe, and the bottom mold of the casting and welding is cooled by supercooled water, cold air or water spray.

[0033] The cast-welded base includes two cylinders respectively disposed on both sides of the placement plate. The cast-welded base is provided with a vertical cylinder for driving the placement plate to move vertically. The placement plate is also provided with protruding ends for fixing the cast-welded base on both sides, and a support surface is provided on both sides of the placement plate. The support surface is provided with a sliding groove. The cast-welded base is also provided with a vertical slide rail for the vertical cylinder to drive the placement plate to move vertically. The placement plate slides vertically by sliding with the vertical slide rail through the sliding groove on the support surface.

[0034] A horizontal cylinder, mounted on the bracket, is used to drive the cast-welded base to move horizontally;

[0035] The bracket is also equipped with a horizontal slide rail for the horizontal cylinder to drive the placement plate to move horizontally, and the cast-welded base is also equipped with a sliding groove that cooperates with the horizontal slide rail. The placement plate slides horizontally by sliding with the horizontal slide rail through the sliding groove of the cast-welded base.

[0036] Immediately after lead injection, water cooling in a cooling tank accelerates the solidification of the manifold. This shortens the single casting and welding cycle, matching the high-speed production pace; and refines the lead grains to improve mechanical strength.

[0037] This invention utilizes a vertical cylinder and a horizontal cylinder to drive the placement plate for fine-tuning, ensuring that the electrode tabs are vertically inserted into the casting cavity. This avoids incomplete soldering caused by electrode tab misalignment and improves connection reliability.

[0038] This utility model of lead-acid battery casting and welding device achieves a green, efficient, and precise upgrade of the casting and welding process through innovative infrared uniform heating and quantitative lead wire melting and casting technology, combined with a highly automated multi-station collaborative system.

[0039] Compared to traditional techniques that require immersing the casting mold in an open lead melting furnace for high-temperature heating, this invention employs two rows of symmetrical infrared heating tubes for precise, surround-type temperature control of the casting mold. This results in uniform heating, rapid heating, and controllable mold temperature, completely eliminating the large amounts of lead fume pollution and lead slag produced by continuous high-temperature lead melting in open furnaces. This significantly improves the working environment and enables cleaner production on the production line. Furthermore, the elimination of the energy-intensive lead melting furnace directly reduces production energy consumption.

[0040] The lead-molten lead addition mechanism, consisting of a lead wire supply unit, a hot-melt nozzle, and a sealed lead-molten tank, combined with a servo motor-driven quantitative lead wire delivery and a cylinder-controlled addition orifice, enables precise on-demand melting of lead wire. The molten lead is then precisely and controllably injected into the casting cavity within a sealed environment via a valve. This avoids the lead evaporation, splashing, and waste of residual material caused by open melting, waste material recovery, and mold movement in traditional processes, significantly improving raw material utilization.

[0041] The entire system, through modular design (multi-station preheating, casting and welding, cooling, etc.) and an automated transfer system (cylinder-driven pusher plate, multiple sets of robotic arms working together), achieves fully automated flow and precise positioning of the casting and welding bottom mold in preheating, lead injection, casting and welding, cooling, mold removal, and cleaning. Combined with a one-to-eight casting and welding bottom mold design and a rapid production cycle of 15-20 seconds per mold, it significantly improves the production line's efficiency and single-machine capacity (up to 12,000-14,000 molds per shift).

The transfer mechanism 5 is used to transfer the casting and welding bottom mold 1 between various stations.

[0061] Specifically, the infrared heating mechanism 3 includes two rows of infrared heating tubes 31, which form a symmetrical heating structure. There is a gap between the two rows of infrared heating tubes 31 for the casting and welding bottom mold 1 to pass through. The casting and welding bottom mold passes through the gap to achieve circumferential heating, eliminate the temperature difference problem of traditional local heating, and ensure the uniformity of the heating temperature of the casting and welding bottom mold.

[0062] The casting and welding bottom mold 1 is provided with support blocks 12 on both sides, and the support blocks 12 are provided with sliding grooves; the transfer mechanism 5 includes: a first slide rail 51, which is provided on both sides of the infrared heating station and the casting and welding station, and the casting and welding bottom mold 1 slides with the first slide rail 51 through the sliding groove on the support block 12; a first drive unit 52, which is used to drive the casting and welding bottom mold 1 to move along the first slide rail 51; and a robot arm 53, which is used to transfer the casting and welding bottom mold 1 located at the casting and welding station after completing one casting and welding operation to the upstream end of the infrared heating station.

[0063] Specifically, the robotic arm 53 includes: a second slide rail 531, located above the infrared heating station and the casting and welding station; a robotic arm base 532, having a slide groove that cooperates with the second slide rail 531, and the robotic arm base 532 is also provided with a lifting arm 5321 and a lifting drive unit 5322 for driving the lifting arm 5321 to lift and lower, the bottom of the lifting arm 5321 is provided with a pair of horizontal moving grippers 53211 and a cylinder 53212 for driving the horizontal moving grippers 53211 to grip or release the casting and welding bottom mold 1; and a second drive unit 533 for driving the robotic arm base 532 to move along the second slide rail 531.

The vertical mounting bracket 6111 is also provided with a flipping unit 61112 for driving the clamping unit 61111 to flip up and down.

[0067] The entire transfer process is automated: mold preheating → quantitative lead injection → electrode tab casting and welding → water cooling → mold removal → cleaning – all without human intervention. This reduces human error, stabilizes product quality, and frees up manpower, reducing labor costs.

[0068] The cylinder pusher mold enables rapid switching between workstations; the robotic arms have clearly defined roles (picking, placing, flipping, and transferring batteries and molds). Modular and efficient collaboration supports an ultra-short production cycle of 15-20 seconds, achieving high single-line capacity (one-outlet eight-mold design, 12,000-14,000 units / shift).

[0069] The lead liquid adding mechanism 2 of this utility model has an opening at the top of the lead liquid tank 21, and a cover plate 211 is provided at the opening.

The lead liquid adding mechanism 2 also includes at least two temperature sensors 25. One temperature sensor is used to detect the temperature of the lead liquid tank 21, and the other temperature sensor is used to detect the temperature of the lead liquid inside the lead liquid tank 21. The lead liquid tank temperature sensor (controlling the hot melt power) and the lead liquid temperature sensor (controlling the pouring timing) are linked to perform real-time temperature control to ensure that the flowability of the lead liquid matches the mold temperature.

[0073] In addition, the lead liquid adding mechanism is equipped with clamping and adjusting screws at both ends, which can adjust the tension between the lead liquid adding mechanism and the casting and welding bottom mold to ensure that no lead liquid overflows during the lead pouring process of the casting and welding bottom mold.

The casting and welding bottom mold is cooled by a cooling tank, which can be done by spraying cold water or other cooling methods. This accelerates the formation of the busbar and terminal posts, completing the casting and welding process. This shortens the single casting and welding cycle and matches the high-speed production cycle.

[0080] This invention utilizes a vertical cylinder and a horizontal cylinder to drive the placement plate for fine-tuning, ensuring that the electrode tabs are vertically inserted into the casting cavity. This avoids incomplete soldering caused by electrode tab misalignment and improves connection reliability.

[0081] When using this utility model:

[0082] Multiple side-by-side cast and welded bottom molds 1 slide into the first slide rail 51 via support blocks 12. The push plate drives the cylinder 522 to push the push plate 521, sending the bottom molds into the infrared heating station in sequence. The upper and lower rows of infrared heating tubes 31 are activated to form a ring heating, and the cast and welded bottom molds 1 pass through the heating gap at a uniform speed.

[0083] The lead wire is pushed by the lead wire drive component 222 driven by the servo motor and enters the lead liquid hot melt tank 2111 through the lead wire limit tube 221; the hot melt nozzle 231 melts the lead wire instantly, and the lead liquid flows into the closed lead liquid tank 21 through the lead liquid inlet 2112.
