Technical Field
[0001] This utility model relates to the field of battery pack side sleeve cutting technology, specifically a battery pack side sleeve cutting device. Background Technology
[0002] Lithium-ion batteries are widely used in electric vehicles, energy storage systems, and consumer electronics due to their high energy density and long cycle life. During battery assembly, heat-shrink tubing is used to protect the battery casing from mechanical damage, oxidation, and short-circuit risks. With the rapid development of the new energy industry and the continuous expansion of battery production scale, the requirements for tubing cutting efficiency, precision, and consistency are increasingly stringent.
[0003] In existing technologies, the battery sleeve cutting process requires operators to measure and mark the sleeve length beforehand, and then use manual or semi-automatic cutting equipment for segmented cutting. This method is inefficient and prone to errors, making it difficult to meet the needs of mass production. While some automated equipment uses PLC to control the feeding length, it still requires individual cutting, which can improve accuracy, but the output per unit time is limited. The single-cut mode cannot match the high-speed cycle of power battery production lines. Therefore, we propose a battery pack side sleeve cutting equipment to solve the above problems.

A mounting rod is fixedly mounted on the mounting frame, and two sets of symmetrically distributed first telescopic rods are slidably mounted within the mounting rod. A second telescopic rod is slidably installed inside each rod. The ends of the two sets of second telescopic rods away from the mounting rod are fixedly connected to a set of adjusting frames located on the outer side. Multiple sets of equidistant limiting frames are slidably installed laterally on the base. The multiple sets of limiting frames are distributed correspondingly with the multiple sets of adjusting frames. Two sets of symmetrically distributed first limiting rods are rotatably installed on the limiting frames. Two sets of symmetrically distributed second limiting rods are rotatably installed on the limiting frames. The cutting blade on the adjusting frame is located between the first and second limiting rods on the corresponding limiting frame. Two sets of symmetrically distributed receiving plates are rotatably installed on the base.
[0006] As a further preferred embodiment of this technical solution, each of the multiple sets of cutting blades is provided with a slot, and a locking rod is rotatably mounted on the mounting bracket. The locking rod is slidably engaged with the multiple sets of cutting blades through the slot. A bidirectional screw is rotatably mounted inside the mounting rod, and a screw tube is rotatably mounted inside each of the two sets of first telescopic rods. The two ends of the bidirectional screw pass through the two corresponding sets of first telescopic rods and are threadedly connected to the first telescopic rods respectively. The two sets of screw tubes pass through the corresponding second telescopic rods and are threadedly connected to the second telescopic rods respectively.
[0007] As a further preferred embodiment of this technical solution, the bidirectional screw is provided with two sets of symmetrically distributed sliding grooves, and two sets of symmetrically distributed sliders are fixedly installed in each of the two sets of sliding grooves. The sliders are arranged corresponding to the sliding grooves, and the screw tube is slidably connected to the bidirectional screw through the sliders.
[0008] As a further preferred embodiment of this technical solution, the limiting frame is provided with a push groove, and the adjusting frame is fixedly installed with a push rod, which is vertically slidably connected to the limiting frame through the push groove.
[0009] As a further preferred embodiment of this technical solution, each of the two sets of first limiting rods is fitted with a first gear, and two sets of symmetrically distributed first racks are slidably installed inside the limiting frame. The two sets of first racks are fixedly connected by a first connecting frame, and the two sets of first racks are respectively meshed with the corresponding first gears. A first cylinder is fixedly installed on the limiting frame, and the first connecting frame is fixedly connected to the output end of the piston rod of the first cylinder.
[0010] As a further preferred embodiment of this technical solution, a second gear is sleeved on each of the two sets of second limiting rods, and two sets of symmetrically distributed second racks are slidably installed inside the limiting frame. The two sets of second racks are fixedly connected by a second connecting frame, and the two sets of second racks are respectively meshed with the corresponding second gears. A second cylinder is fixedly installed on the limiting frame, and the second connecting frame is fixedly connected to the output end of the piston rod of the second cylinder.
[0011] As a further preferred embodiment of this technical solution, a third gear is fixedly sleeved on each of the two sets of receiving plates, and two sets of symmetrically distributed third racks are slidably installed in the base. The two sets of third racks are respectively meshed with the corresponding third gears. A double-rod cylinder is fixedly installed in the base, and the two sets of third racks are respectively fixedly connected to the output ends of the two sets of piston rods of the double-rod cylinder.
[0012] This utility model provides a battery pack side sleeve cutting device, which has the following advantages: (1) This utility model drives multiple sets of adjustment frames to move synchronously through the linkage control of the first telescopic rod and the second telescopic rod symmetrically distributed on the mounting rod. Combined with the cross-hinged connecting rod structure on the adjustment frame, it realizes the precise synchronous adjustment of the spacing between multiple sets of cutting blades. The stable transmission mechanism formed by the cross-distributed connecting rods ensures that multiple sets of cutting blades move in parallel during the adjustment process, avoids spacing deviation, and improves the consistency of cutting length. After the adjustment is completed, the device can realize single-segment multi-cutting of battery sleeves, which effectively improves the cutting efficiency compared with the traditional single-cutting mode.
[0013] (2) The present invention enables multiple sets of limiting frames to slide synchronously on the base along with the corresponding adjusting frame by setting push rods and push grooves. Because the battery sleeve waiting to be cut is positioned by the action of the first limiting rod and the second limiting rod on the limiting frame corresponding to the adjusting frame, the displacement of the battery sleeve during the cutting process is avoided, which affects the cutting accuracy. At the same time, after the cutting is completed, the two sets of receiving plates installed on the base are rotated synchronously to complete the one-time discharge of the cut battery sleeve, reducing the discharge time so as to quickly enter the next batch of battery sleeve cutting and processing.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, a battery pack side sleeve cutting device includes a base 1, a mounting frame 2 above the base 1, and multiple sets of equidistantly distributed adjusting frames 3 slidably mounted on the mounting frame 2. Each set of adjusting frames 3 is rotatably mounted with a cutting blade 4, and each set of adjusting frames 3 is rotatably mounted with two sets of cross-distributed connecting rods 7. The ends of the connecting rods 7 between adjacent sets of adjusting frames 3 are rotatably connected via a rotating shaft. A mounting rod 8 is fixedly mounted on the mounting frame 2, and two sets of symmetrically distributed first telescopic rods 9 are slidably mounted inside the mounting rod 8. A second telescopic rod 10 is slidably mounted inside each of the two sets of first telescopic rods 9, and the ends of the two sets of second telescopic rods 10 away from the mounting rod 8 are fixedly connected to a set of adjusting frames 3 located on the outer side. Multiple sets of equal-distance adjusting frames 3 are slidably mounted laterally on the base 1. The system includes multiple sets of limiting frames 15, corresponding to multiple sets of adjusting frames 3. Two sets of symmetrically distributed first limiting rods 18 and two sets of symmetrically distributed second limiting rods 23 are rotatably mounted on each limiting frame 15. The cutting blades 4 on the adjusting frames 3 are positioned between the first limiting rods 18 and the second limiting rods 23 on the corresponding limiting frames 15. Two sets of symmetrically distributed receiving plates 28 are rotatably mounted on the base 1. Each set of cutting blades 4 has a slot 5. A locking rod 6 is rotatably mounted on the mounting frame 2, and the locking rod 6 slides and engages with the multiple sets of cutting blades 4 through the slots 5. A bidirectional screw 11 is rotatably mounted inside the mounting rod 8. A screw tube 13 is rotatably mounted inside each of the two sets of first telescopic rods 9. The two ends of the bidirectional screw 11 pass through the two sets of corresponding... The first telescopic rod 9 is threadedly connected to the first telescopic rod 9. Two sets of screw tubes 13 pass through the corresponding second telescopic rods 10 and are threadedly connected to the second telescopic rods 10. Two sets of symmetrically distributed sliding grooves 12 are opened on the bidirectional screw 11. Two sets of symmetrically distributed sliders 14 are fixedly installed in each of the two sets of sliding grooves 12. The sliders 14 are correspondingly set with the sliding grooves 12. The screw tubes 13 are slidably sleeved with the bidirectional screw 11 through the sliders 14. Through the linkage control of the first telescopic rod 9 and the second telescopic rod 10 symmetrically distributed on the mounting rod 8, multiple sets of adjusting frames 3 are driven to move synchronously. Combined with the cross-hinged connecting rods 7 structure on the adjusting frame 3, the precise synchronous adjustment of the spacing of multiple sets of cutting blades 4 is realized. The stable transmission mechanism formed by the cross-hinged connecting rods 7 ensures that multiple During adjustment, the cutting blades 4 maintain parallel movement to avoid spacing deviation and improve cutting length consistency. After adjustment, the device can perform single-stage multi-segment cutting of battery sleeves, effectively improving cutting efficiency compared to the traditional single-stage cutting mode. During the rotation of the bidirectional screw 11 in the mounting rod 8, the two sets of first telescopic rods 9 slide synchronously under the limiting action of the mounting rod 8. Under the limiting action of the slider 14 and the slide groove 12, the screw tube 13, sliding with the first telescopic rod 9, rotates synchronously with the bidirectional screw 11. Therefore, under the limiting action of the first telescopic rod 9, the two sets of second telescopic rods 10 slide synchronously. After adjusting the spacing between the multiple sets of cutting blades 4, the rotation of the clamping rod 6 achieves synchronous drive of the multiple sets of cutting blades 4. Simultaneously...The hydraulic cylinder on base 1 adjusts the positions of the mounting bracket 2 and the cutting blade 4 to facilitate the smooth cutting of the battery sleeve.
[0017] like Figure 4 , Figure 5 and Figure 6 As shown, the limiting frame 15 has a push groove 16, and the adjusting frame 3 is fixedly installed with a push rod 17. The push rod 17 is vertically slidably connected to the limiting frame 15 through the push groove 16. Two sets of first limiting rods 18 are each fitted with a first gear 19. Two sets of symmetrically distributed first racks 20 are slidably installed inside the limiting frame 15. The two sets of first racks 20 are fixedly connected by a first connecting frame 21. The two sets of first racks 20 are respectively meshed with the corresponding first gear 19. A first cylinder 22 is fixedly installed on the limiting frame 15, and the first connecting frame 21 is flexibly connected to the first cylinder 22. The output end of the plunger is fixedly connected. Two sets of second gears 24 are sleeved on each of the two sets of second limiting rods 23. Two sets of symmetrically distributed second racks 25 are slidably installed inside the limiting frame 15. The two sets of second racks 25 are fixedly connected by a second connecting frame 26. The two sets of second racks 25 are respectively meshed with the corresponding second gears 24. A second cylinder 27 is fixedly installed on the limiting frame 15. The second connecting frame 26 is fixedly connected to the output end of the piston rod of the second cylinder 27. Two sets of third gears 29 are fixedly sleeved on each of the two sets of receiving plates 28. Two sets of... The third racks 30 are distributed in a manner that meshes with the corresponding third gears 29. A double-rod cylinder 31 is fixedly installed inside the base 1. The two sets of third racks 30 are fixedly connected to the output ends of the two sets of piston rods of the double-rod cylinder 31. The push rod 17 and the push groove 16 enable multiple sets of limit frames 15 to slide synchronously on the base 1 along with the corresponding adjustment frame 3. When the first cylinder 22 or the second cylinder 27 on the limit frame 15 is started, it drives the corresponding first connecting frame 21 or the second connecting frame 26, as well as the first rack 20 and the second rack 25. Sliding on the limiting frame 15, the corresponding first gear 19 and second gear 24 cause the two sets of symmetrically distributed first limiting rods 18 to rotate inward synchronously, and the two sets of symmetrically distributed second limiting rods 23 to rotate inward synchronously, clamping and fixing the battery sleeve on the base 1 to prevent displacement during the cutting process. After the cutting is completed, the double-rod cylinder 31 in the base 1 is started to drive the two sets of third racks 30 to move outward synchronously, and then, in conjunction with the third gear 29, the two sets of receiving plates 28 to flip downward synchronously, so that the cut battery sleeve can be discharged synchronously.
[0018] This utility model provides a battery pack side sleeve cutting device. The specific working principle is as follows: Through the linkage control of the first telescopic rod 9 and the second telescopic rod 10 symmetrically distributed on the mounting rod 8, multiple sets of adjusting frames 3 are driven to move synchronously. Combined with the cross-hinged connecting rod 7 structure on the adjusting frame 3, precise synchronous adjustment of the spacing between multiple sets of cutting blades 4 is achieved. The stable transmission mechanism formed by the cross-distributed connecting rods 7 ensures that the multiple sets of cutting blades 4 maintain parallel movement during adjustment, avoiding spacing deviation and improving the consistency of cutting length. After adjustment, the device can achieve single-stage multi-segment cutting of the battery sleeve, effectively improving cutting efficiency compared to the traditional single-stage cutting mode. During the rotation of the bidirectional screw 11 in the mounting rod 8, the two sets of first telescopic rods 9 slide synchronously under the limiting action of the mounting rod 8. Under the limiting action of the slider 14 and the slide groove 12, the screw tube 13, which slides with the first telescopic rod 9, rotates synchronously with the bidirectional screw 11. Therefore, under the limiting action of the first telescopic rod 9, the two sets of second telescopic rods 10 slide synchronously. After completing the adjustment of the spacing between multiple sets of cutting blades 4, the clamping rod 6 rotates... During operation, multiple sets of cutting blades 4 are driven synchronously. Simultaneously, the positions of the mounting bracket 2 and the cutting blades 4 are adjusted by the hydraulic cylinders on the base 1 to facilitate the smooth cutting of the battery sleeve. The push rod 17 and push groove 16 allow multiple sets of limiting brackets 15 to slide synchronously on the base 1 along with their corresponding adjusting brackets 3. When the first cylinder 22 or the second cylinder 27 on the limiting bracket 15 is activated, it drives the corresponding first connecting bracket 21 or the second connecting bracket 26, as well as the first rack 20 and the second rack 25, to move on the limiting bracket 15. The sliding mechanism, in conjunction with the corresponding first gear 19 and second gear 24, causes the two sets of symmetrically distributed first limiting rods 18 to rotate inward synchronously, and the two sets of symmetrically distributed second limiting rods 23 to rotate inward synchronously, clamping and fixing the battery sleeve located on the base 1 to prevent displacement during the cutting process. After the cutting is completed, the double-rod cylinder 31 in the base 1 is activated to drive the two sets of third racks 30 to move outward synchronously, which in turn, in conjunction with the third gear 29, causes the two sets of receiving plates 28 to flip downward synchronously, thus completing the synchronous discharge of the cut battery sleeve.
