Technical Field

[0001] The invention relates to the technical field of battery processing, and in particular to a rotary battery changing device. Background Art

[0002] At present, in the lithium battery production process, the same production line is required to be compatible with the production of multiple products, and be able to meet the requirements of fast and accurate model changeover, simple and safe operation, strong versatility, standardization, good compatibility, and simple structure when switching between different products. However, in actual production, if the same production line needs to achieve flexible production and frequently switch to produce different products, it is necessary to perform new model change operations on the product fixtures, that is, it is necessary to frequently replace the limit parts of the battery welding position, because the welding position and welding trajectory of different products are very different.

[0003] In the related art, the limit parts are generally locked by screws. The screws need to be disassembled and installed during the model change process. After the model change, the limit parts are positioned and adjusted according to the actual product position to accurately dock with other equipment. This positioning and adjustment operation brings difficulties to production personnel and requires a lot of labor. It is impossible to quickly switch different limit parts to limit the battery, which affects the production and processing efficiency of the battery. Summary of the invention

[0006] By adopting the above technical scheme, when processing the battery, the limit piece on the switching disk is against the battery to limit the battery. When processing batteries of different models and lengths, it is necessary to replace the limit pieces of different lengths to limit the battery. At this time, the piston rod of the cylinder is contracted to drive the rack to slide, and the rack and the gear are against each other, driving the gear to rotate. At this time, the outer ring of the one-way bearing is against the inner ring and rotates at the same time, thereby driving the rotating shaft on the inner ring of the one-way bearing to rotate. When the rotating shaft rotates, it drives the ratchet and the switching disk to rotate. After the ratchet rotates, the pawl is against the ratchet to fix the rotating shaft. At this time, the limit piece on the switching disk is quickly replaced; then the cylinder drives the rack to extend to reset the rack. Due to the limitation of the one-way bearing, the gear on the outer ring of the one-way bearing is idle, and the rotating shaft cannot rotate, so that it is convenient to quickly replace the next limit piece. The operation is convenient and quick. The limit piece on the annular disk can be quickly replaced by extending and retracting the piston rod of the cylinder, thereby achieving the effect of improving production and processing efficiency.

[0007] Preferably, a group of mounting bolts are symmetrically arranged on the switching disk, and the mounting bolts pass through the switching disk and are threadedly connected to the end wall of the rotating shaft.

[0008] By adopting the above technical solution, the switching disk and the rotating shaft can be easily disassembled and assembled by installing bolts.

[0009] Preferably, the switching disk is provided with a plurality of mounting holes for inserting the limiting member, and the inner wall of the mounting hole is threadedly connected with a clamping bolt, and the end wall of the clamping bolt is against the limiting member.

[0011] Preferably, a ball bearing is provided on the mounting frame, and the rotating shaft and the ball bearing are connected to each other.

[0012] By adopting the above technical solution, the ball bearing is helpful to reduce the friction between the rotating shaft and the mounting frame.

[0013] Preferably, a connecting piece is integrally provided on the end wall of the rack, a mounting block is provided on the piston rod of the cylinder, and the rack is detachably connected to the mounting block via the connecting piece.

[0014] By adopting the above technical solution, the rack and the mounting block are detachably connected through the connecting piece, which facilitates the disassembly and assembly of the rack and the cylinder and facilitates the maintenance of the device.

[0016] By adopting the above technical solution, when the rack and the cylinder need to be disassembled and assembled, the connecting block is inserted into the connecting groove, and the limit block is abutted against the inner wall of the limit groove to quickly connect the rack and the mounting block. When the cylinder drives the mounting block to slide, the rack can be driven to slide through the connecting piece.

[0017] Preferably, the mounting frame is provided with a paddle that abuts against the ratchet.

By setting a mounting frame, a cylinder, a rack, a rotating shaft, a switching disk, a stopper, a one-way bearing, a gear, a ratchet and a pawl, the piston rod of the cylinder is contracted to drive the rack to slide, the rack and the gear are against each other, and the gear is driven to rotate. At this time, the outer ring of the one-way bearing is against the inner ring and rotates at the same time, thereby driving the rotating shaft on the inner ring of the one-way bearing to rotate. When the rotating shaft rotates, it drives the ratchet and the switching disk to rotate. After the ratchet rotates, the pawl is against the ratchet. Due to the limitation of the one-way bearing, the gear on the outer ring of the one-way bearing rotates idly, and the rotating shaft cannot rotate, so that it is convenient to quickly replace the next stopper. The operation is convenient and quick. The stopper on the annular disk can be quickly replaced by retracting the piston rod of the cylinder, thereby achieving the effect of improving production and processing efficiency. 2. By setting the mounting hole and the holding bolt, the holding bolt is rotated to separate the holding bolt and the limiter from each other.

When the cylinder drives the mounting block to slide, the rack can be driven to slide through the connecting piece. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] The present application discloses a rotary battery changing device. Figures 1 to 3 It includes a mounting frame 1, a cylinder 2 is arranged on the side wall of the mounting frame 1, the cylinder 2 is arranged in the horizontal direction, a connecting bolt 22 is arranged through the top corner of the cylinder 2, the connecting bolt 22 is threadedly connected to the mounting frame 1, and the cylinder 2 is fixedly connected to the mounting frame 1 through the connecting bolt 22. The piston rod of the cylinder 2 is connected to a rack 21, and the rack 21 is slidably arranged on the mounting frame 1. A rotating shaft 3 is rotatably arranged on the mounting frame 1 through a ball bearing 7, and the length direction of the rotating shaft 3 is perpendicular to the length direction of the rack 21. One end of the rotating shaft 3 is connected to a switching disk 31, and a plurality of limit members 32 are arranged on the switching disk 31. The length of each limit member 32 is different, so as to limit batteries of different lengths during processing.

[0028] Reference Figure 2 and Figure 3The rotating shaft 3 is sleeved with a one-way bearing 4, the inner ring of the one-way bearing 4 is connected to the rotating shaft 3, the outer ring of the one-way bearing 4 is fixedly connected to a gear 41, and the gear 41 is meshed with the rack 21. The rotating shaft 3 is keyed with a ratchet 5, and the mounting frame 1 is provided with a pawl 51 that abuts against the ratchet 5 through a spring. When the battery is processed, the limit piece 32 on the switching disk 31 is abutted against the battery, and the battery is limited by the limit piece 32. When batteries of different models and lengths are processed, it is necessary to replace the limit pieces 32 of different lengths to limit the battery. At this time, the piston rod of the cylinder 2 is contracted to drive the rack 21 to slide, and the rack 21 is abutted against the gear 41, driving the gear 41 to rotate. At this time, the outer ring of the one-way bearing 4 is tightly abutted against the inner ring and rotates at the same time, thereby driving the rotating shaft 3 on the inner ring of the one-way bearing 4 to rotate. When the rotating shaft 3 rotates, it drives the ratchet 5 and the switching disk 31 to rotate. After the ratchet 5 rotates, the ratchet pawl 51 abuts against the ratchet 5 to fix the rotating shaft 3. At this time, the limit piece 32 on the switching disk 31 is quickly replaced, and then the cylinder 2 drives the rack 21 to extend, so that the rack 21 is reset. Due to the configuration of the one-way bearing 4, the gear 41 on the outer ring of the one-way bearing 4 idles, and the rotating shaft 3 cannot rotate, thereby facilitating the rapid replacement of the next limit piece 32.

[0029] Reference Figure 3 A group of mounting bolts 311 are symmetrically arranged on the switching disk 31. The mounting bolts 311 penetrate the switching disk 31 and are threadedly connected with the end wall of the rotating shaft 3. The mounting bolts 311 facilitate the disassembly and assembly between the switching disk 31 and the rotating shaft 3. The switching disk 31 is provided with a plurality of mounting holes 6 for inserting the limiter 32. The inner wall of the mounting hole 6 is threadedly connected with a tightening bolt 61, and the end wall of the tightening bolt 61 abuts against the limiter 32. The tightening bolt 61 is rotated to separate the tightening bolt 61 from the limiter 32. At this time, the limiter 32 can be taken out of the mounting hole 6, so that different limiters 32 can be installed between the switching disk 31 to improve the applicability of the device.

[0030] Reference Figure 1 , a connecting piece 8 is integrally provided on the end wall of the rack 21, a mounting block 9 is provided on the piston rod of the cylinder 2, the connecting piece 8 includes a connecting block 81 and a limiting block 82, the connecting block 81 is integrally formed with the rack 21, two limiting blocks 82 are symmetrically provided on the side wall of the connecting block 81, the limiting blocks 82 are integrally formed with the connecting block 81, and a connecting groove 91 is provided on the mounting block 9 for the connecting block 81 and the limiting block 82 to be inserted and abutted against each other. The connecting block 81 is inserted into the connecting groove 91, and the limiting block 82 abuts against the inner wall of the limiting groove, so that the rack 21 and the mounting block 9 are quickly connected. When the cylinder 2 drives the mounting block 9 to slide, the connecting piece 8 can drive the rack 21 to slide, so that the rack 21 and the cylinder 2 can be disassembled and assembled, which is convenient for maintenance of the device.

[0031] Reference Figure 2 A paddle 10 that abuts against the ratchet 5 is provided on the mounting frame 1. When the ratchet 5 rotates, the paddle 10 continuously abuts against the surface of the ratchet 5, so that a sense of frustration and sound are generated when the device rotates, which is convenient for identifying the working status of the device.

[0032] The implementation principle of a rotary battery changing device in the embodiment of the present application is as follows: when it is necessary to replace the limit piece 32 of different lengths to limit the battery, the piston rod of the cylinder 2 is first contracted to drive the rack 21 to slide, and the rack 21 is abutted against the gear 41, driving the gear 41 to rotate. At this time, the outer ring of the one-way bearing 4 is abutted against the inner ring and rotates at the same time, thereby driving the rotating shaft 3 on the inner ring of the one-way bearing 4 to rotate. When the rotating shaft 3 rotates, it drives the ratchet 5 and the switching disk 31 to rotate. After the ratchet 5 rotates, the ratchet pawl 51 is abutted against the ratchet 5 to fix the rotating shaft 3. The limiting member 32 on the switching disk 31 is quickly replaced, and then the cylinder 2 drives the rack 21 to extend to reset the rack 21. Due to the limitation of the one-way bearing 4, the gear 41 on the outer ring of the one-way bearing 4 idles, and the rotating shaft 3 cannot rotate, so that it is convenient to quickly replace the next limiting member 32. Several limiting members 32 can be configured to meet the processing requirements of different batteries. The operation is convenient and fast. The limiting member 32 on the annular disk can be quickly replaced by extending and retracting the piston rod of the cylinder 2, thereby achieving the effect of improving production and processing efficiency.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
