Description

Technical Field

[0001] This utility model belongs to the field of lithium battery production technology, and in particular relates to a winding machine for lithium battery production. Background Technology

[0002] Lithium batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. One step in the lithium battery manufacturing process is the winding of the battery pack.

[0003] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: Most of the machines currently used for battery pack winding require manual installation of the winding drum onto the designated winding mechanism and locking. After the winding work is completed, manual unlocking is required, which makes the operation troublesome and reduces efficiency.

[0004] To address this issue, we propose a winding machine for lithium battery production. Utility Model Content

[0005] The main purpose of this utility model is to provide a winding machine for lithium battery production, which realizes automatic positioning of the winding drum, ensures that it does not shake during operation, and eliminates the need for manual positioning, thereby improving the efficiency of winding drum assembly and disassembly and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A winding machine for lithium battery production includes a support platform and a battery pack winding mechanism disposed on the support platform. A mounting base is welded on the support platform. The battery pack winding mechanism includes a first servo motor mounted on one side wall of the mounting base, a side support shaft coaxially connected to the first servo motor, a fixed cylinder coaxially connected to the side of the side support shaft facing away from the first servo motor, and a winding cylinder slidably sleeved on the fixed cylinder.

[0008] An inner mounting groove and an inner drive chamber are formed inside the fixed cylinder. A second servo motor is horizontally mounted on the inner wall of the inner mounting groove. A main bevel gear and two driven bevel gears meshing on both sides of the main bevel gear are provided in the inner drive chamber. An inner support shaft is coaxially connected to the main bevel gear and the two driven bevel gears respectively. The inner support shaft on the main bevel gear is coaxially connected to the second servo motor.

[0009] Storage grooves are formed on both sides of the outer wall of the fixed cylinder on the side facing away from the first servo motor. Two screws are coaxially connected to the inner support shafts of the bevel gears. A positioning block is threaded on each of the two screws, and both positioning blocks abut against the winding cylinder, thereby temporarily limiting the position of the winding cylinder and keeping the winding cylinder stable when winding the battery pack.

[0010] As a preferred embodiment, the side support shaft is located on the side of the mounting base facing away from the first servo motor, and the side support shaft is rotatably connected to the mounting base, so that the side support shaft can operate stably.

[0011] As a preferred embodiment, the three inner support shafts are rotatably connected to three side walls of the inner drive chamber, so that the main bevel gear and the two driven bevel gears can operate stably.

[0012] As a preferred embodiment, the two screws are symmetrically positioned on both sides of the inner drive chamber, and both screws are rotatably connected to the inner wall of the receiving groove, so that both screws can operate stably.

[0013] As a preferred embodiment, the four side walls of the positioning block are all in contact with the inner wall of the receiving groove; so that when the screw is running, it can drive the positioning block to move along the inner wall of the receiving groove, thereby fixing or releasing the winding drum.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] This lithium battery production winding machine drives a first servo motor to rotate a side support shaft, a fixed cylinder, and a winding cylinder, continuously winding the battery pack onto the winding cylinder. After winding is complete, a second servo motor drives a main bevel gear and two driven bevel gears, causing two screws to rotate and retract a positioning block into a receiving slot, allowing the winding cylinder to be removed. An empty winding cylinder can then be installed on the fixed cylinder for subsequent winding operations. This achieves automatic positioning of the winding cylinder, ensuring it does not shake during operation and eliminating the need for manual positioning, thus improving the efficiency of winding cylinder assembly and disassembly.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A winding machine for lithium battery production includes a support platform 1 and a battery pack winding mechanism disposed on the support platform 1. A mounting base 2 is welded on the support platform 1. The battery pack winding mechanism includes a first servo motor 3 mounted on one side wall of the mounting base 2, a side support shaft 4 coaxially connected to the first servo motor 3, a fixed cylinder 5 coaxially connected to the side of the side support shaft 4 facing away from the first servo motor 3, and a winding cylinder 6 slidably sleeved on the fixed cylinder 5. The side support shaft 4 is located on the side of the mounting base 2 facing away from the first servo motor 3, and the side support shaft 4 is rotatably connected to the mounting base 2, so that the side support shaft 4 can operate stably.

[0023] An inner mounting groove 7 and an inner drive chamber 9 are formed inside the fixed cylinder 5. A second servo motor 8 is horizontally mounted on the inner wall of the inner mounting groove 7. A main bevel gear 10 and two driven bevel gears 11 meshing on both sides of the main bevel gear 10 are provided in the inner drive chamber 9. An inner support shaft 12 is coaxially connected to the main bevel gear 10 and the two driven bevel gears 11. The inner support shaft 12 on the main bevel gear 10 is coaxially connected to the second servo motor 8. The three inner support shafts 12 are rotatably connected to three side walls of the inner drive chamber 9, so that the main bevel gear 10 and the two driven bevel gears 11 can operate stably.

[0024] On both sides of the outer wall of the fixed cylinder 5 facing away from the first servo motor 3, there are storage grooves 13. Two screws 14 are coaxially connected to the inner support shafts 12 on the bevel gear 11. The two screws 14 are symmetrical on both sides of the inner drive chamber 9, and both screws 14 are rotatably connected to the inner wall of the storage groove 13, so that both screws 14 can operate stably. A positioning block 15 is threaded on each of the two screws 14, and both positioning blocks 15 abut against the winding cylinder 6, thereby temporarily limiting the position of the winding cylinder 6, so that the winding cylinder 6 remains stable when winding the battery pack. The four side walls of the positioning block 15 are all in contact with the inner wall of the storage groove 13, so that when the screw 14 is running, it can drive the positioning block 15 to move along the inner wall of the storage groove 13, thereby fixing or releasing the winding cylinder 6.

[0025] This lithium battery production winding machine: Before use, the two positioning blocks 15 are respectively located in the two receiving slots 13. At this time, the winding drum 6 is slidably sleeved onto the outer wall of the fixed drum 5 from one end. Then, the second servo motor 8 is driven to rotate the main bevel gear 10, causing the two driven bevel gears 11 to rotate and drive the two screws 14 to rotate, so that the two positioning blocks 15 move away from each other along the inner wall of the receiving slot 13. Figure 4 As shown, the two positioning blocks 15 abut against the winding drum 6, preventing one end of the winding drum 6 from slipping off the fixed drum 5, while the other end of the winding drum 6 is in contact with the fixed drum 5, thus ensuring the stability of the winding drum 6. Then, the first servo motor 3 is driven to run, driving the side support shaft 4, the fixed drum 5, and the winding drum 6 to rotate and perform the battery pack winding work on the outer wall of the winding drum 6. After this work is completed, the second servo motor 8 is reversed, and the two positioning blocks 15 are returned to their original positions, so that the winding drum 6 can be removed from the fixed drum 5, and the winding work of the next winding drum 6 can be carried out immediately. Since the positioning and contact positioning of the winding drum 6 do not require manual operation, the efficiency is improved.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
