Description

Technical Field

[0001] This utility model relates to the field of nickel-metal hydride cylindrical battery technology, and in particular to an intelligent fully automatic winding machine for nickel-metal hydride cylindrical batteries. Background Technology

[0002] Chinese patent CN202220292306.9 discloses a nickel-metal hydride cylindrical battery cell winding mechanism. It can adapt to cells of different lengths by setting a moving stage controlled by a screw, and can also use a fixed seat to conveniently and quickly clamp and fix the cells, effectively improving the efficiency of cell replacement and improving the overall processing efficiency of cell winding.

[0003] However, the following shortcomings still exist: When the battery cell is wound, the workers manually place the battery cell in the fixed seat, which may cause the lengths of the two ends of the battery cell in the fixed seats on both sides to be unequal. This may cause the winding position to deviate from the expected position during the winding process, reducing the winding quality. Although the battery cell can be clamped and centered by moving two sets of moving tables in opposite directions, the moving tables still need to be manually adjusted when changing the battery cell, which increases the labor intensity of the workers and reduces the work efficiency. In addition, the thickness of the finished product may vary depending on the number of times the battery cell is wound. When the number of windings is too high, the two sets of battery cell supports may interfere with each other, which also requires manual handling by the workers, reducing the work efficiency.

[0004] Therefore, this application provides a fully automated intelligent winding machine for nickel-metal hydride cylindrical batteries to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide an intelligent fully automatic winding machine for nickel-metal hydride cylindrical batteries, which aims to solve the problems that when workers manually place the battery cells in the fixed seats during the winding process, the lengths of the two ends of the battery cell in the fixed seats on both sides may be unequal, and when the number of windings is too large, the adjacent sets of battery cell supports may interfere.

[0006] To achieve the above objectives, this application provides the following technical solution: a fully automatic intelligent winding machine for nickel-metal hydride cylindrical batteries, comprising a support frame, on which a first movable platform and a second movable platform are slidably connected. The support frame is also provided with a bidirectional screw for adjusting the positions of the first and second movable platforms. One end of the bidirectional screw passes through the support frame and is connected to a handwheel. Guide holes are provided on both the first and second movable platforms, and adjusting blocks slide within the guide holes. Multiple sets of adjusting blocks are provided, and a fixed seat is mounted on each adjusting block. A pre-tightening spring for aligning the battery cells is provided within the fixed seat. A transmission mechanism is provided on the first movable platform, and a drive motor is connected to the fixed seat through the transmission mechanism, enabling automatic alignment when the battery is placed into the equipment.

[0007] Preferably, the fixed base also includes a transmission rod, one end of which is mounted on the fixed base, and the other end of which is connected to the transmission mechanism. The transmission rod is rotatably connected to the adjusting block via a bearing. The fixed base has an installation groove, and a top plate slides in the installation groove. One end of a pre-tension spring is connected to the top plate, and the other end of the pre-tension spring is connected to the bottom surface of the installation groove, making it more convenient and faster to disassemble and assemble the battery cell.

[0008] Preferably, a worm gear is also connected to the transmission rod, and the transmission rod is connected to the transmission mechanism through the worm gear, so that the equipment can be easily controlled.

[0009] Preferably, the transmission mechanism further includes mounting blocks, a cover, and a worm gear. Multiple sets of mounting blocks are provided. Both ends of the worm gear are connected to the first movable platform through the mounting blocks. The mounting blocks are provided with bearing seats adapted to the worm gear. The worm gear is located below the fixed seat and is adapted to a worm wheel. The drive motor is mounted on the first movable platform. One end of the worm gear passes through the mounting block and is connected to the drive motor. Both the worm gear and the drive motor are connected with adapted transmission gears. The cover serves to protect the transmission mechanism.

[0010] Preferably, the top surface of the inner wall of the guide hole is provided with a sliding groove that connects to the outside. The adjusting block slides in the sliding groove and the guide hole. The adjusting block is limited by the locking screw, so that the equipment can adjust the distance between the fixed seats and avoid the problem of mutual interference caused by too many windings.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, the pre-tightening spring and top plate installed in the fixed base ensure that after the battery cell is installed in the fixed base, the pre-tightening spring in the fixed base on both sides, together with the top plate, centers the battery cell between the two sets of fixed bases. This achieves the centering effect of the battery cell while retaining the effect of quick assembly and disassembly, eliminating the need for workers to manually adjust the distance between the moving platforms, reducing the labor intensity of workers, and improving work efficiency.

[0013] In this invention, the fixed base is mounted on the adjusting block via a transmission rod, allowing the equipment to adjust the spacing between the adjusting blocks according to the number of winding operations. This avoids interference between adjacent cells caused by excessive winding operations, effectively improving processing quality. It eliminates the need for manual handling by workers, reducing their workload and increasing work efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] refer to Figure 1-4 The diagram shows an intelligent fully automatic winding machine for nickel-metal hydride cylindrical batteries, including a support frame 1. A first moving platform 6 and a second moving platform 7 are slidably connected to the support frame 1. The support frame 1 is also provided with a bidirectional screw 2 for adjusting the first moving platform 6 and the second moving platform 7 to move towards or away from each other. The bidirectional screw 2 passes through the support frame 1 and is connected to a handwheel 5. The first moving platform 6 and the second moving platform 7 are both provided with guide holes 15 for installing adjustment blocks 14. Multiple sets of adjustment blocks 14 are provided, and the adjustment blocks 14 are connected to a fixing seat 4 for fixing the battery cells.

[0022] As one embodiment of this invention, to make it more convenient and faster to replace the battery cell, the fixed base 4 also includes a transmission rod 20. One end of the transmission rod 20 is connected to the fixed base 4, and the other end is connected to the transmission mechanism 11. The transmission rod 20 is mounted on the adjusting block 14 through a bearing seat. The fixed base 4 has an installation groove 18, and a pre-tightening spring 9 is provided in the installation groove 18. The top plate 19 slides in the installation groove 18 through the pre-tightening spring 9, so that when the battery cell is fixed in the fixed base 4, the battery cell can be centered by the pre-tightening spring 9 in the fixed base 4. At the same time, when replacing the battery cell after winding, it is not necessary to adjust the position of the first moving platform 6 and the second moving platform 7 through the handwheel 5 and the bidirectional screw 2. The battery cell only needs to be moved to either side so that it is pressed by the top plate 19 to press the pre-tightening spring 9, and the other end can be taken out from the fixed base 4.

[0023] As one embodiment of this invention, to enable more convenient and faster control of the device, the transmission mechanism 11 further includes a mounting block 12 and a worm gear 13. Two sets of mounting blocks 12 are provided, and both ends of the worm gear 13 are connected to the first moving platform 6 through the two sets of mounting blocks 12. The mounting blocks 12 are also provided with bearing seats adapted to the worm gear 13, and one end of the worm gear 13 passes through the mounting block 12 and is connected to the drive motor 3. The worm gear 13 and the drive motor 3 are provided with compatible transmission gears. The first moving platform 6 is also provided with a cover 8 for protecting the worm gear 13. The worm gear 13 is located below the transmission rod 20, and the worm gear 13 is adapted to the worm wheel 17. The worm wheel 17 meshes with the worm gear 13, so that when the drive motor 3 drives the worm gear 13 to move, the worm wheel 17 drives the fixed seat 4 to rotate synchronously through the transmission rod 20.

[0024] As one implementation method in this embodiment, in order to prevent interference between adjacent cells when the number of winding turns of the cell is too large, a sliding groove 16 connected to the outside is provided on the upper top surface of the inner wall of the guide hole 15. The adjusting block 14 slides in the sliding groove 16 and the guide hole 15, so that the spacing between multiple sets of adjusting blocks 14 can be adjusted, and the adjusting block 14 is also limited by the locking screw 10.

[0025] The working principle of this utility model is as follows: In use, the operator first adjusts the distance between the first moving platform 6 and the second moving platform 7 according to the length of the battery cell. Then, based on the required number of turns of the battery cell, the distance between the two sets of fixed seats 4 is adjusted. By moving the adjusting block 14 in the first moving platform 6 and the second moving platform 7 within the sliding groove 16, the position of the fixed seat 4 in the guide hole 15 is adjusted, thus achieving the effect of adjusting the distance between the fixed seats 4. Then, by rotating the locking screw 10, the position of the adjusting block 14 in the sliding groove 16 is fixed. Next, one end of the battery cell is inserted into one of the fixed seats 4. The battery cell compresses the pre-tension spring 9 through the top plate 19. Then, the other end of the battery cell is inserted into the corresponding fixed seat 4 on the other side. Through the pre-tension spring 9 in the fixed seats 4 on both sides of the battery cell and the top plate 19, the portion of the battery cell in the two sets of fixed seats 4 is made the same, achieving the desired effect of adjusting the distance between the fixed seats 4. After the battery cell is aligned, the double-ended screw 2 is rotated by turning the nut. The double-ended screw 2 pushes the clamping plate to clamp and position the battery cell in the fixed seat 4. Then, the drive motor 3 can be started. The drive motor 3 drives the worm gear 13 to rotate through the transmission gear. The worm wheel 17, which meshes with the worm gear 13, rotates synchronously. The worm wheel 17 drives the fixed seat 4 to rotate through the transmission rod 20, so that the battery cell can be wound. After the battery cell is wound, only the double-ended screw 2 needs to be turned by turning the nut to move the clamping plate. The battery cell is no longer clamped and positioned. Then, the battery cell is moved to the fixed seat 4 on either side. The battery cell is squeezed by the top plate 19 to the pre-tightening spring 9, so that the other end of the battery cell can be taken out from the opposite fixed seat 4. Then the battery cell can be taken out as a whole without adjusting the distance between the first moving table 6 and the second moving table 7 by the handwheel 5, which improves the speed of battery cell replacement.
