Description

Technical Field

[0001] This utility model relates to the field of battery pack processing technology, specifically a six-axis welding device for battery pack processing. Background Technology

[0002] In battery pack manufacturing, welding is a crucial process for ensuring the structural stability and electrical connection reliability of the battery pack. Currently, the industry commonly uses automated welding equipment to weld various components of the battery pack to improve processing efficiency and welding quality. Among these, six-axis robotic arms, with their flexible motion trajectory and high-precision operation, are widely used in battery pack welding operations, enabling welding at different locations within the battery pack to meet various welding requirements.

[0003] However, existing battery pack welding devices still have some shortcomings in practical applications. On the one hand, battery packs often require multi-sided welding during the welding process, but traditional devices have a relatively fixed fixing structure for the battery packs, making it difficult to flexibly flip them over. This results in the need for manual adjustment of the battery pack's posture multiple times, which not only increases the number of operation steps but may also affect welding accuracy. On the other hand, battery packs of different specifications vary in size and shape, and the existing clamping structure has a limited adjustment range, making it difficult to stably clamp battery packs of different specifications. This poor adaptability affects the versatility and processing efficiency of the welding device. Utility Model Content

This technical solution resolves some shortcomings of existing battery pack welding devices mentioned in the background art in practical applications.

This necessitates multiple manual adjustments to the battery pack's orientation, increasing operational steps and potentially affecting welding accuracy. Secondly, battery packs of different specifications vary in size and shape, and existing clamping structures have limited adjustment range, making it difficult to stably clamp battery packs of different specifications, resulting in poor adaptability and consequently affecting the versatility and processing efficiency of the welding device.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Example 1

[0021] Please refer to Figures 1 to 3 As shown, a six-axis welding device for battery pack processing includes a base plate 1. A support frame 2 is fixedly connected to the left and right edges of the top of the base plate 1. The two support frames 2 are symmetrically arranged, and a disc 3 is rotatably connected to each other on opposite sides. A drive assembly 4 is installed inside the support frame 2 to drive one of the discs 3 to rotate. A square frame 5 is fixedly connected between the two discs 3. Two clamping assemblies 6 are adjustablely mounted on the square frame 5. A mounting frame 8 is connected to the rear edge of the top of the base plate 1 via a horizontal moving mechanism 7. A six-axis robotic arm 9 is mounted on the top of the mounting frame 8, and a welding torch 10 is connected to the end effector connection of the six-axis robotic arm 9.

[0022] Those skilled in the art will understand that the base plate 1 serves as the foundation of the device, and the uprights 2 on the left and right sides of its top support the rotating disks 3. The drive assembly 4 can drive one of the disks 3 to rotate, thereby causing the square frame 5 and the clamping assembly 6 between the two disks 3 to rotate synchronously. The rear side of the base plate 1 drives the mounting frame 8 and the six-axis robotic arm 9 to move horizontally through the horizontal moving mechanism 7. The welding gun 10 at the end of the six-axis robotic arm 9 can flexibly adjust the welding position.

[0023] It enables multi-angle welding and position adjustment of battery packs, and combines the flexibility of a six-axis robotic arm to meet complex welding requirements, providing basic structural support for subsequent flipping and clamping adjustments.

[0024] Example 2

[0025] Furthermore, fixed shafts 11 are fixedly connected to the opposite sides of the two uprights 2. The two fixed shafts 11 are coaxial. A circular groove 12 coaxial with the fixed shaft 11 is opened on the side of the disc 3 away from the square frame 5. A bearing 13 is fixed in the circular groove 12. The inner ring of the bearing 13 is interference-fitted with the outer ring of the fixed shaft 11, and the outer ring is interference-fitted with the inner wall of the circular groove 12.

[0026] As will be understood by those skilled in the art, the fixed shaft 11 on the opposite side of the stand 2 is engaged with the circular groove 12 of the disc 3 through the bearing 13. The inner ring of the bearing 13 is interference-fitted with the fixed shaft 11, and the outer ring is interference-fitted with the circular groove 12, to ensure that the disc 3 rotates stably around the fixed shaft 11.

[0027] Reduce frictional resistance when the disc 3 rotates, improve rotational stability, ensure positional accuracy during battery pack flipping, and avoid affecting welding quality due to shaking.

[0028] Example 3

[0029] Furthermore, the drive assembly 4 includes a fixed plate 401 fixedly connected inside the frame 2. A gear 402 is rotatably connected to the inner side of the fixed plate 401 via a rotating shaft. A gear ring 403 that meshes with the gear 402 is fixedly connected to the outer ring of one of the discs 3. A worm gear 404 is fixedly connected to the other end of the rotating shaft connected to the gear 402. A first motor 405 is also fixedly connected inside the frame 2. A worm 406 that meshes with the worm gear 404 is fixedly connected to the output end of the first motor 405.

[0030] As will be understood by those skilled in the art, in the drive assembly 4, the first motor 405 drives the worm 406 to rotate, the worm 406 meshes with the worm wheel 404, causing the shaft connecting the worm wheel 404 and the gear 402 to rotate, and the gear 402 meshes with the gear ring 403 on the outer ring of the disk 3, ultimately driving the disk 3 to rotate. Utilizing the self-locking characteristics of the worm wheel 404 and worm 406, the disk 3 is ensured to remain stably at any angle, facilitating precise control of the battery pack flipping angle. Simultaneously, the power transmission efficiency is improved through the gear 402 and gear ring 403 transmission.

[0031] Example 4

[0032] Furthermore, the clamping assembly 6 includes a first U-shaped plate 601. Sliding sleeves 602 are fixedly connected to the tops of the two vertical plates of the first U-shaped plate 601. The sliding sleeves 602 are slidably mounted on the square frame 5. A locking screw 603 is threaded onto the outer side of each sliding sleeve 602. A second U-shaped plate 604 is hinged to the top of one sliding sleeve 602, and two spaced-apart locking plates 606 are fixedly connected to the top of the other sliding sleeve 602. A locking head 605 is fixedly connected to the free end of the second U-shaped plate 604. The gap between the locking head 605 and the two locking plates 606 is matched. A first circular hole is provided on the horizontal direction of the 5th plate. A second circular hole corresponding to the first circular hole is provided on both locking plates 606. A fixing bolt 607 is provided between the first circular hole and the two second circular holes. A vertically arranged threaded rod 608 is threadedly connected to the middle of the horizontal plate of the second U-shaped plate 604. A pressure plate 609 is rotatably connected to the bottom end of the threaded rod 608. Two first guide rods 610 are slidably provided on the horizontal plate of the second U-shaped plate 604 and are vertically arranged and symmetrically distributed on both sides of the threaded rod 608. The bottom ends of the two first guide rods 610 are fixedly connected to the top of the pressure plate 609.

[0033] Those skilled in the art will understand that the sliding sleeve 602 of the clamping assembly 6 slides along the square frame 5 and is fixed in position by the tightening screw 603 to adjust the spacing; the second U-shaped plate 604 rotates around the hinge point of the sliding sleeve 602, and after the locking head 605 is inserted into the gap between the two locking plates 606, it is locked by the fixing bolt 607; rotating the threaded rod 608 drives the pressure plate 609 to rise and fall, and the first guide rod 610 ensures that the pressure plate 609 moves smoothly.

[0034] The clamping distance and clamping degree can be flexibly adjusted according to the battery pack specifications to adapt to different sizes of battery packs. The fixing bolts 607 and pressure plates 609 work together to improve clamping stability and prevent battery pack displacement during welding.

[0035] Example 5

[0036] Furthermore, a knob 14 is fixedly connected to the top of the threaded rod 608, a first flexible pad 15 is provided on the top of the horizontal plate of the first U-shaped plate 601, and a second flexible pad 16 is provided on the bottom of the horizontal plate of the second U-shaped plate 604.

[0037] Those skilled in the art will understand that the knob 14 at the top of the threaded rod 608 facilitates manual adjustment of the height of the pressure plate 609; the first flexible pad 15 of the first U-shaped plate 601 and the second flexible pad 16 of the second U-shaped plate 604 are in direct contact with the battery pack. The knob 14 improves ease of operation, the flexible pads prevent damage to the surface of the battery pack during clamping, and the increased friction further enhances clamping stability.

[0038] Example 6

[0039] Furthermore, the horizontal moving mechanism 7 includes a fixed base 701 fixedly connected to the top of the base plate 1 near the rear edge. The top of the fixed base 701 has a mounting groove. A horizontally arranged lead screw 702 is rotatably connected in the mounting groove. Two second guide rods 703, parallel to the lead screw 702 and symmetrically distributed on both sides of the lead screw 702, are fixedly connected in the mounting groove. A mounting bracket 8 is threadedly connected to the lead screw 702 and slidably connected to the two second guide rods 703. A second motor 704 is fixedly connected to the outer side of the base plate 1. The output end of the second motor 704 is fixedly connected to one end of the lead screw 702.

[0040] Those skilled in the art will understand that in the horizontal moving mechanism 7, the second motor 704 drives the lead screw 702 to rotate, and the mounting frame 8 moves horizontally along the lead screw 702 and the second guide rod 703, thereby driving the six-axis robotic arm 9 and the welding torch 10 to adjust their horizontal positions. This expands the horizontal working range of the welding torch 10, and in conjunction with the multi-directional movement of the six-axis robotic arm 9, enables welding coverage of different areas of the battery pack. The second guide rod 703 ensures that the mounting frame 8 moves smoothly and improves the position control accuracy.

[0041] The working principle and usage procedure of this device are as follows: First, adjust the clamping assembly 6 according to the battery pack specifications: Loosen the clamping screw 603 on the sliding sleeve 602, allowing the sliding sleeves 602 of the two clamping assemblies 6 to slide along the square frame 5 to a suitable distance, then tighten the clamping screw 603; Place the battery pack on the first flexible pads 15 of the two first U-shaped plates 601, rotate the second U-shaped plate 604 to make the locking head 605 embed between the two locking plates 606, insert the fixing bolt 607 to fix it, rotate the threaded rod 608 through the knob 14 to drive the pressure plate 609 down along the first guide rod 610 until the second flexible pad 16 presses the battery pack; Start the second motor 704 of the horizontal moving mechanism 7 to drive the lead screw. Rotation 702 causes the mounting frame 8 to move along the second guide rod 703, adjusting the six-axis robotic arm 9 and welding torch 10 to the initial welding position. The welding torch 10 is controlled by the six-axis robotic arm 9 to weld the battery pack. When it is necessary to flip the battery pack, the first motor 405 of the drive assembly 4 is started, and the worm gear 406 drives the worm wheel 404 to rotate, causing the gear 402 to mesh with the gear ring 403 to drive the disc 3 to rotate around the fixed shaft 11 and the bearing 13. This, in turn, drives the battery pack to flip to the preset angle through the square frame 5. The angle is maintained by the self-locking characteristics of the worm wheel 404 and the worm gear 406, and the welding torch 10 continues to complete the welding of the remaining area. The entire process can be covered by the coordinated movement of the horizontal moving mechanism 7 and the six-axis robotic arm 9.
