Description

Technical Field

[0001] This utility model relates to the field of lithium battery wire bonding technology, and in particular to a lithium battery resistance welding wire bonding device. Background Technology

[0002] Lithium-ion battery resistance welding wire bonding equipment is a device used in the lithium-ion battery production process to connect the battery tabs to the wires. In today's energy field, lithium-ion batteries, with their significant advantages such as high energy density, long cycle life, and no memory effect, are widely used in electric vehicles, energy storage systems, and various consumer electronics products. Resistance welding wire bonding is a crucial step in the lithium-ion battery production process, aiming to achieve a reliable electrical connection between the battery tabs and the wires. However, due to various factors, such as fluctuations in welding parameters, electrode wear, and differences in the surface condition of the materials to be welded, wire bonding failures occur frequently. These failed wire bonding lithium-ion batteries are often not properly handled under traditional production methods.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: under the traditional production model, lithium batteries with failed wire bonding are often not properly handled. Some companies, due to the lack of an effective collection and treatment mechanism, often discard these wastes as ordinary garbage. However, in reality, lithium batteries with failed wire bonding contain many materials with recycling value. This means that randomly discarding lithium batteries with failed wire bonding will not only cause a huge waste of resources, but also cause serious environmental pollution. Therefore, a lithium battery resistance welding wire bonding device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problem that, in traditional production models, lithium batteries with failed wire bonding are often not properly disposed of. Some companies, lacking effective collection and processing mechanisms, often discard these wastes as ordinary garbage. However, lithium batteries with failed wire bonding contain many materials with recycling value. This results in the drawback that indiscriminately discarding lithium batteries with failed wire bonding not only causes a huge waste of resources but also leads to serious environmental pollution. Therefore, this invention proposes a lithium battery resistance welding wire bonding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lithium battery resistance welding wire bonding device, comprising a base, a support frame, a turntable fixture module, a CCD module, a resistance welding module, a robot arm, and a lower electrode assembly. A fixing frame is fixedly connected to the surface of the base, and a storage box is slidably connected to the inner wall of the fixing frame. Two irregularly shaped plates are fixedly connected to the surface of the fixing frame, and a rotating shaft is fixedly connected to the inner wall of the irregularly shaped plates. A fixing plate is rotatably connected to the arc surface of the rotating shaft. An insertion hole is opened on the surface of the fixing plate. Two L-shaped plates are fixedly connected to the surface of the storage box. An insertion rod is slidably inserted into the L-shaped plate. The insertion rod is slidably connected to the inner wall of the insertion hole of the fixing plate, and a pull plate is fixedly connected to one end of the insertion rod.

[0006] The aforementioned components achieve the following effects: they collect and process lithium batteries with failed wire bonding. Among these failed lithium batteries, some materials, such as metal wires and electrodes, may have certain recycling value. Through centralized collection, these wastes can be sorted and recycled, thereby reducing raw material costs. This also prevents lithium batteries with failed wire bonding from being improperly disposed of and potentially discarded as ordinary waste, causing resource waste and environmental pollution, and reducing the company's operating costs.

[0007] Preferably, the arc surface of the rotating shaft is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the irregular plate and the fixed plate, respectively.

[0008] The effect achieved by the above components is that, under the action of the torsion spring, the fixing plate is automatically opened and fixed at a certain angle, which improves the convenience of the device.

[0009] Preferably, the arc surface of the insertion rod is fitted with a spring, and the two ends of the spring are fixedly connected to the pull plate and the L-shaped plate, respectively.

[0010] The effect achieved by the above components is that, under the action of the spring, the insertion rod is automatically springed back and inserted into the hole of the fixing plate, thus improving the practicality of the device.

[0011] Preferably, the surface of the storage box is fixedly connected to two connecting plates, and a handle is fixedly connected to one side of the two connecting plates that are close to each other.

[0012] The effect achieved by the above-mentioned components is that by setting up a handle, a force-bearing point is provided for moving the storage box, especially when the storage box is full of items and heavy, making it easier for operators to move the storage box.

[0013] Preferably, the inner wall of the fixing frame is rotatably connected with a plurality of round beads, and the arc surface of the round beads is slidably connected to the storage box.

[0014] The effect achieved by the above components is that by setting the ball, the sliding friction between the storage box and the fixed frame is transformed into rolling friction. The coefficient of friction of rolling friction is usually less than that of sliding friction, which makes it easier for the storage box to move within the fixed frame and requires less effort when pushing or pulling.

[0015] Preferably, a filter plate is fixedly connected to the inner wall of the storage box, a square hole is opened on the surface of the storage box, a collection box is slidably connected to the inner wall of the square hole of the storage box, a drive rod is threaded into the collection box, a baffle is fixedly connected to the bottom surface of the filter plate, a limit plate is fixedly connected to one end of the drive rod, and the surface of the limit plate is slidably connected to the baffle.

[0016] The effect achieved by the above-mentioned components is that by setting up a filter plate, the materials that may fall off from the bonding wires, electrodes and other materials on the lithium batteries with failed bonding are classified and collected, avoiding the situation where materials that may fall off, such as bonding wires and electrodes, are too small to be easily classified when mixed in with the lithium batteries with failed bonding.

[0017] Preferably, a limiting rod is fixedly connected to the inner wall of the collection box, and the arc surface of the limiting rod is slidably connected to the limiting plate.

[0018] The effect achieved by the above components is that by setting a limit rod, the driving rod is prevented from rotating the limit plate past the baffle area, thus avoiding the situation where the collection box slides out of the storage box due to not being properly secured.

[0019] This invention achieves the effect of collecting and processing lithium batteries with failed wire bonding. Among the lithium batteries with failed wire bonding, some materials such as metal wires and electrodes may have certain recycling value. By collecting them centrally, these wastes can be classified and sorted, and recyclable materials can be recycled and reused, thereby reducing raw material costs. This also prevents lithium batteries with failed wire bonding from being improperly disposed of and potentially discarded as ordinary garbage, causing resource waste and environmental pollution, and reducing the operating costs of enterprises.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model provides a technical solution: a lithium battery resistance welding wire bonding device, comprising a base 1, a support frame 2, a turntable fixture module 3, a CCD module 4, a resistance welding module 5, a robot arm 6, and a lower electrode assembly 7. A fixing frame 8 is fixedly connected to the surface of the base 1, and a storage box 9 is slidably connected to the inner wall of the fixing frame 8. Two irregularly shaped plates 10 are fixedly connected to the surface of the fixing frame 8, and a rotating shaft 11 is fixedly connected to the inner wall of the irregularly shaped plates 10. A fixing plate 12 is rotatably connected to the arc surface of the rotating shaft 11. An insertion hole is opened on the surface of the fixing plate 12. Two L-shaped plates 14 are fixedly connected to the surface of the storage box 9, and an insertion rod 15 is slidably inserted into the L-shaped plate 14. The insertion rod 15 is inserted into the insertion hole of the fixing plate 12. The inner wall of the sliding connection is connected, and one end of the insertion rod 15 is fixedly connected to the pull plate 16, which achieves the effect of collecting and processing lithium batteries with failed wire bonding. Among the lithium batteries with failed wire bonding, some materials such as metal wire bonding and electrodes may have certain recycling value. Through centralized collection, these wastes can be classified and sorted, and recyclable materials can be recycled and reused, thereby reducing raw material costs and avoiding the situation where lithium batteries with failed wire bonding are not properly disposed of and may be discarded as ordinary garbage, causing resource waste and environmental pollution, and reducing the company's operating costs. The arc surface of the rotating shaft 11 is fitted with two torsion springs 13. The two ends of the torsion springs 13 are fixedly connected to the irregular plate 10 and the fixed plate 12 respectively. Under the action of the torsion springs 13, the fixed plate 16 is fixedly connected to the fixed plate 12. The automatic opening and fixing of plate 12 at a certain angle improves the convenience of the device. A spring 17 is fitted onto the arc surface of the insertion rod 15, with both ends of the spring 17 fixedly connected to the pull plate 16 and the L-shaped plate 14 respectively. The force of the spring 17 automatically springs the insertion rod 15 back into the insertion hole of the fixing plate 12, improving the practicality of the device. Two connecting plates 18 are fixedly connected to the surface of the storage box 9, and a handle 19 is fixedly connected to the side of the two connecting plates 18 that is close to each other. The handle 19 provides a leverage point for moving the storage box 9, especially when the storage box 9 is full and heavy, making it easier for operators to move the storage box 9. Several rotatable connections are made to the inner wall of the fixing frame 8. A ball 26, with its arc-shaped surface slidably connected to the storage box 9, transforms the sliding friction between the storage box 9 and the fixed frame 8 into rolling friction. The coefficient of rolling friction is typically lower than that of sliding friction, allowing the storage box 9 to move more easily within the fixed frame 8, requiring less effort when pushing or pulling. A filter plate 20 is fixedly connected to the inner wall of the storage box 9. A square hole is formed on the surface of the storage box 9, and a collection box 21 is slidably connected to the inner wall of the square hole. A drive rod 22 is threaded into the collection box 21. A baffle 24 is fixedly connected to the bottom surface of the filter plate 20. One end of the drive rod 22 is fixedly connected to a limit plate 23, and the surface of the limit plate 23 is slidably connected to the baffle 24. By setting the filter plate 20...This system effectively classifies and collects materials such as solder wires and electrodes that may fall off from lithium batteries with failed soldering, preventing these small materials from getting mixed in with the failed batteries and making them difficult to classify. A limiting rod 25 is fixedly connected to the inner wall of the collection box 21. The arc surface of the limiting rod 25 is slidably connected to the limiting plate 23. By setting the limiting rod 25, the system prevents the drive rod 22 from rotating the limiting plate 23 past the baffle 24 area, thus preventing the collection box 21 from sliding out of the storage box 9 if it is not properly secured.

[0027] Working principle: When the operator needs to use the storage box 9, they push the handle 19. The handle 19 transmits the thrust to the storage box 9 through the connecting plate 18. The storage box 9 then slides within the fixed frame 8 under the thrust. At this time, the arc surface of the ball 26 contacts the bottom surface of the storage box 9, converting the sliding friction between the storage box 9 and the fixed frame 8 into rolling friction, thereby reducing the resistance generated during movement. Pulling the pull plate 16 causes the insertion rod 15 to slide within the L-shaped plate 14. At this time, the spring 17 is in a stretched state. Then, the fixed plate 12 is rotated, and the fixed plate 12 rotates on the arc surface of the rotating shaft 11. The torsion spring 13 is in a torsional state until the fixed plate 12 stops at the L-shaped plate 14. Then, the pull plate 16 is released, and the spring 17 releases the stretched force, causing the insertion rod 15 to automatically spring back and insert into the insertion hole of the fixed plate 12, completing the fixation of the storage box 9. Then, the collection box 21 is placed into the storage box. Inside the storage box 9, the drive rod 22 is rotated, which drives the limiting plate 23 to rotate until the limiting plate 23 contacts the limiting rod 25, thus fixing the collection box 21. Then, the lithium batteries with failed wire bonding are placed into the storage box 9. The materials such as the wire bonding wires and electrodes that fall off the lithium batteries with failed wire bonding will fall into the collection box 21 through the filter plate 20, leaving the lithium batteries with failed wire bonding on the filter plate 20. This completes the classified collection and achieves the effect of collecting and processing the lithium batteries with failed wire bonding. Among the lithium batteries with failed wire bonding, some materials such as metal wire bonding wires and electrodes may have certain recycling value. Through centralized collection, these waste products can be classified and sorted, and recyclable materials can be recycled and reused, thereby reducing raw material costs and preventing the lithium batteries with failed wire bonding from being improperly disposed of and possibly discarded as ordinary garbage, causing resource waste and environmental pollution, and reducing the company's operating costs.
