Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery processing, in particular to a series-parallel welding processing and production device for power lithium batteries. Background Art

[0002] In the production process of power lithium batteries, series-parallel welding processing is an extremely critical link. The welding quality is directly related to the performance, safety and service life of the battery pack. With the rapid development of new energy vehicles, energy storage systems and other fields, the market demand for power lithium batteries has shown explosive growth, and the quality and performance requirements of batteries are becoming increasingly stringent. Therefore, how to achieve efficient, precise, stable and adaptable series-parallel welding processing of power lithium batteries for diversified production needs has become an important issue that needs to be urgently solved in the industry.

[0003] Currently, there are a variety of power lithium battery series and parallel welding processing and production devices on the market. Most of these existing devices use traditional conveying and welding methods. In terms of the drive system, they usually rely on a single drive motor to drive a conveyor belt or chain to continuously transport the carrier with the battery pack to the welding station for welding. In terms of welding position control, simple positioning blocks or photoelectric sensors are generally used to achieve the approximate positioning of the battery pack to guide the welding assembly during the welding operation.

[0004] However, the existing technology has many significant defects, which seriously restrict the efficiency and quality of the series and parallel welding of power lithium batteries:

[0005] The existing continuous conveying method cannot be flexibly adjusted to the welding rhythm. During the welding process, if the welding time is long, the conveyor belt will continue to run, causing battery packs to pile up in front of the welding station, not only taking up a lot of production space but also increasing the difficulty of subsequent processing. If the welding time is short, the conveyor belt will be intermittently idle, resulting in energy waste and low production efficiency. At the same time, this production method requires frequent manual monitoring and adjustment, which increases labor costs and cannot meet the needs of large-scale, high-efficiency production.

[0006] The rigid pushing method will generate a large impact force when pushing the battery pack, which can easily cause damage to the battery pack and mechanical components, shortening the service life of the equipment. At the same time, the rigid pushing method cannot ensure the smoothness and continuity of the pushing process. At the moment when the pushing rod contacts and separates from the battery pack, jamming, shaking and other phenomena may occur, affecting the delivery accuracy and welding quality of the battery pack. In addition, this pushing method lacks an effective reset mechanism. After multiple pushes, the position of the pushing rod may deviate, resulting in inaccurate subsequent pushes.

[0017] Compared with the existing technology, it has the following beneficial effects:

[0018] Realize automated intermittent conveying and welding: By turning on the drive motor and relying on the linkage of a series of mechanical structures, the drive motor drives the drive rod to rotate, and then drives the transmission rod, slide frame and other components, and finally the push rod intermittently pushes the placement seat, mobile table and battery pack to the side of the welding assembly. This automated intermittent conveying method does not require frequent manual operation, greatly improves production efficiency, reduces labor costs, and at the same time ensures that the welding process can proceed stably according to the predetermined rhythm, providing reliable guarantee for large-scale and high-efficiency battery pack welding production.

[0019] Precise control of welding position: During the pushing process, the elastic force of the first damping spring and the second damping spring is used, and the pushing block is in contact with the triangular block to achieve precise control of the moving position of the placement seat. When the pushing block pushes the triangular block and other related components to move and compresses the second damping spring, it is reset under the action of the spring. At the same time, the first damping spring pushes the placement seat to move in the opposite direction to make the pushing block fit the triangular block. This series of actions ensures that the placement seat can stop accurately in the appropriate position after each push, so that the welding assembly can accurately weld the battery pack, effectively improving the welding quality, reducing welding defects caused by position deviation, and improving the product qualification rate.

[0020] Ensure the stability and reliability of the pushing process: When the slide moves toward the side of the first conveyor and the next push rod contacts the placement seat, the push rod, rotating shaft, and counterweight rod rotate and stretch the tension spring, and then rotate and reset under the elastic force of the tension spring. This design allows the push rod to smoothly transition during the contact and separation process with the placement seat, avoiding damage to mechanical components caused by rigid impact and extending the service life of the equipment. At the same time, the elastic force of the tension spring ensures that the push rod can be stably reset to prepare for the next push, ensuring the continuity and stability of the entire pushing process, and further ensuring the reliability of intermittent transportation of battery packs.

[0021] Adapt to different production needs: The design of this mechanical structure has certain flexibility and adjustability. By adjusting parameters such as the speed of the drive motor, the elastic coefficient of the damping spring, and the tension of the tension spring, the moving speed and intermittent time of the placement seat can be flexibly changed according to different production requirements, such as welding speed and battery pack specifications, thereby meeting diverse production needs, improving the versatility and applicability of the equipment, and providing strong technical support for enterprises to cope with market changes.

[0022] The overall structure is compact and reasonable: the entire device organically integrates multiple functional modules such as drive, transmission, propulsion and reset. The components are compactly arranged and work in harmony. This compact structural design not only saves space occupied by the equipment and facilitates installation and layout in the production workshop, but also facilitates the coordinated work between the components, reduces the loss in the energy transfer process, improves the overall operating efficiency of the equipment, reduces energy consumption, and meets the requirements of modern industrial production for energy conservation, emission reduction and efficient use of resources.

[0023] Highly adaptable to diverse battery specifications: The device drives the lead screw to rotate through the adjusting motor, thereby moving the adjusting block laterally, and then drives the moving seat to move on the auxiliary rod and the rotating rod through the transmission of the control rod and the connecting rod. This ingenious design allows the distance between adjacent moving seats to be flexibly adjusted, and the welding gun is installed on the moving seat, which means that the spacing between adjacent welding guns can change with the movement of the moving seat. In this way, no matter what specifications and sizes of battery packs are faced, the spacing between the welding guns can be adjusted through simple operations to make it accurately correspond to the positions of different welding points on the battery pack, greatly enhancing the equipment's adaptability to battery packs of different specifications, meeting the production needs of diversified products on the market, and providing strong support for enterprises to expand their business scope and enhance their market competitiveness.

[0024] Accurately adjust the welding angle: During the lateral movement of the movable base and the welding gun, they drive the slide bar and the gear bar to move synchronously laterally. At this time, the control motor is turned on to drive the gear bar to rotate. The gear bar and the gear bar engage with each other, thereby driving the gear bar to move, and then driving the slide bar to move, and finally realizing the rotation of the welding gun on the movable base. This design enables the welding angle of the welding gun to be precisely adjusted according to actual welding requirements. Whether it is flat welding, vertical welding or overhead welding, the best welding effect can be obtained by adjusting the welding angle, which effectively improves the welding quality, reduces the occurrence of welding defects, and ensures the firmness and reliability of the battery pack welding.

[0037] The limiting member 67 includes a connecting plate 68 fixedly mounted on one side of the bottom of the placement seat 63, a driving motor 69 fixedly mounted on the connecting plate 68, an output end of the driving motor 69 fixedly connected to a driving rod 610, the other end of the driving rod 610 is rotatably connected to a transmission rod 611, and the other end of the transmission rod 611 is rotatably connected to a slide frame 612 slidably mounted on the frame 1; a row of mounting seats 613 are fixedly connected to the bottom of the slide frame 612, a rotating shaft 614 is rotatably connected to the mounting seat 613, a push rod 615 and a counterweight rod 616 are fixedly connected to the outer wall of the rotating shaft 614, and the push rod 615 and the counterweight rod 616 are in a V-shaped structure, and a counterweight rod 616 is set between the slide frame 612. There is a tension spring 617, and the push rod 615 corresponds to the bottom position of the placement seat 63. By turning on the drive motor 69 to drive the drive rod 610 to rotate synchronously, the drive rod 610 drives the transmission rod 611 to move back and forth, so that the transmission rod 611 drives the slide 612 located on the frame 1 to move back and forth, so that the slide 612 drives the mounting seat 613, the rotating shaft 614, the push rod 615, and the counterweight rod 616 to move back and forth. When the push rod 615 moves toward the side of the second conveying member 3, when the push rod 615 contacts the placement seat 63, it can push the placement seat 63, the push block 64, the moving platform 4, and the battery pack 5 to move toward the side of the welding assembly 7, and compress the first damping spring 65;

[0038] The limiting member 67 includes a support plate 618 fixedly mounted on the mounting plate 61, a row of sliding rods 619 are slidably connected to the support plate 618, a triangular block 620 is fixedly connected to the top of the sliding rod 619, and a limiting block 621 is fixedly connected to the bottom of the sliding rod 619, and the limiting block 621 is located at the bottom of the support plate 618. A second damping spring 622 is provided between the triangular block 620 and the support plate 618 and is sleeved on the sliding rod 619. Push blocks 64 are fixedly connected to both sides of the bottom end of the placement seat 63, and the positions of the push blocks 64 and the triangular blocks 620 correspond to each other; a cross bar 623 is fixedly connected to the side wall of the triangular block 620, and a cylinder 624 is fixedly installed on both sides of the mounting plate 61. The output end of the cylinder 624 is fixedly connected to a pressure plate 625, and the pressure plate 625 is located at the top of the cross bar 623. When the pushing block 64 contacts the triangular block 620, it can push the triangular block 620, the sliding rod 619, and the limit block 621 to move downward and compress the second damping spring 622. When the pushing block 64 moves to one side of the triangular block 620, under the elastic force of the second damping spring 622, it can push the triangular block 620, the sliding rod 619, and the limit block 621 to move and reset. Under the elastic force of the first damping spring 65, it can push the placement seat 63 and the pushing block 64 to move toward the side of the first conveying member 2, so that the pushing block 64 is in contact with the triangular block 620.

[0039] When the slide 612 moves toward the side of the first conveyor 2, when the next push rod 615 contacts the placement seat 63, the push rod 615, the rotating shaft 614, and the counterweight rod 616 rotate and stretch the tension spring 617. When the push rod 615 moves to the side of the placement seat 63, the push rod 615, the rotating shaft 614, and the driving member 66 rotate and reset under the elastic force of the tension spring 617. This reciprocating process can push the placement seat 63, the moving platform 4, and the battery pack 5 to intermittently move toward the side of the welding assembly 7, so that the welding assembly 7 can weld the intermittently moving battery pack 5.

[0040] In the embodiment of the present invention, the driving motor 69 is turned on to drive the driving rod 610 to rotate synchronously, and the driving rod 610 drives the transmission rod 611 to move back and forth, so that the transmission rod 611 drives the slide 612 located on the frame 1 to move back and forth, so that the slide 612 drives the mounting seat 613, the rotating shaft 614, the pushing rod 615, and the counterweight rod 616 to move back and forth. When the pushing rod 615 moves toward the second conveying member 3, when the pushing rod 615 contacts the placement seat 63, it can push the placement seat 63, the pushing block 64, the moving platform 4, and the battery pack 5 to move toward the welding assembly 7, and compress the first damping spring 65;

[0041] When the pushing block 64 contacts the triangular block 620, it can push the triangular block 620, the sliding rod 619, and the limit block 621 to move downward and compress the second damping spring 622. When the pushing block 64 moves to one side of the triangular block 620, under the elastic force of the second damping spring 622, it can push the triangular block 620, the sliding rod 619, and the limit block 621 to move and reset. Under the elastic force of the first damping spring 65, it can push the placement seat 63 and the pushing block 64 to move toward the side of the first conveying member 2, so that the pushing block 64 and the triangular block 620 are in contact with each other.

[0042] When the slide 612 moves toward the side of the first conveying member 2, when the next push rod 615 contacts the placement seat 63, the push rod 615, the rotating shaft 614, and the counterweight rod 616 rotate and stretch the tension spring 617. When the push rod 615 moves to the side of the placement seat 63, the push rod 615, the rotating shaft 614, and the driving member 66 rotate and reset under the elastic force of the tension spring 617. This reciprocating process can push the placement seat 63, the moving platform 4, and the battery pack 5 to intermittently move toward the side of the welding assembly 7, so that the welding assembly 7 can perform welding on the intermittently moving battery pack 5.

[0043] By turning on the drive motor 69, a series of mechanical linkages are used, namely, the drive motor 69 drives the drive rod 610 to rotate, which in turn drives the transmission rod 611, the slide frame 612 and other components, and ultimately causes the push rod 615 to intermittently push the placement seat 63, the movable platform 4 and the battery pack 5 toward the side of the welding assembly 7. This automated intermittent conveying method eliminates the need for frequent manual operation, greatly improving production efficiency and reducing labor costs. At the same time, it ensures that the welding process can proceed stably according to the predetermined rhythm, providing reliable guarantees for large-scale, high-efficiency battery pack 5 welding production. During the pushing process, the elastic force of the first damping spring 65 and the second damping spring 622, combined with the contact between the push block 64 and the triangular block 620, achieves precise control of the moving position of the placement seat 63. When the push block 64 pushes the triangular block 620 and other related components to move and compress the second damping spring 622, it then resets under the action of the spring. At the same time, the first damping spring 65 pushes the placement seat 63 and other components to move in the opposite direction so that the push block 64 fits the triangular block 620. This series of actions ensures that the placement seat 63 can accurately stop at the appropriate position after each push, allowing the welding assembly 7 to accurately weld the battery pack 5, effectively improving the welding quality, reducing welding defects caused by position deviation, and improving the product qualification rate. When the slide 612 moves toward the side of the first conveyor 2 and the next push rod 615 contacts the placement seat 63, the push rod 615, the rotating shaft 614, and the counterweight rod 616 rotate and stretch the tension spring 617, and then rotate and reset under the elastic force of the tension spring 617. This design allows the push rod 615 to smoothly transition between contact and separation with the placement seat 63, avoiding damage to mechanical components caused by rigid impact and extending the service life of the equipment. At the same time, the elastic force of the tension spring 617 ensures that the push rod 615 can be stably reset to prepare for the next push, ensuring the continuity and stability of the entire pushing process, and further ensuring the reliability of the intermittent delivery of the battery pack 5.

By turning on the adjustment motor 75, the screw rod 73 is driven to rotate synchronously.

[0047] When the movable seat 76 and the welding gun 77 move laterally, the movable seat 76 and the welding gun 77 can drive the slide bar 714 and the gear bar 713 to move laterally, that is, the gear bar 713 is laterally located at the gear bar 712 and moves laterally, and then the control motor 711 is turned on to drive the gear bar 712 to rotate synchronously, and the gear bar 712 drives the gear bar 713 to move, so that the gear bar 713 drives the slide bar 714 to move, and then drives the welding gun 77 located at the movable seat 76 to rotate through the slide bar 714, so that the welding angle of the welding gun 77 can be adjusted.
