Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery cell winding technology, specifically to an automatic battery cell winding machine. Background Technology
[0002] In the production process of lithium batteries, the positive electrode, negative electrode, and separator are first wound into a cell, then the cell is placed into a casing, electrolyte is injected into the casing, and finally the casing is sealed. The winding of the cell is inseparable from the winding machine, also known as an automatic cell winding machine. This type of equipment is used in battery manufacturing, primarily to precisely wind the various components of the battery (such as the positive electrode, negative electrode, and separator) together to form a cell. This equipment plays a crucial role in the battery manufacturing process, ensuring the battery's performance and quality.
[0003] Currently, battery cell winding machines require pressure rollers to press the free ends of the cells onto a winding shaft during winding. The winding shaft is then driven by a motor to complete the winding process. However, using pressure rollers to fix the free ends of the cells is prone to slippage during shaft rotation, leading to loosening of the wound cells. Therefore, we propose an automatic battery cell winding machine. Utility Model Content

[0017] Compared with the prior art, in use, the linear drive module drives the first frame to move towards the U-shaped frame, allowing the clamping part to clamp one end of the battery cell. After the clamping part clamps the free end of the battery cell, it travels a certain distance under the drive of the linear drive module, creating a gap between the clamping part and the pressure plate to prevent the clamping part from contacting the pressure plate when rotating. When the battery cell is wound to a preset number of turns, it is clamped by the pressure plate, and then the cutter cuts the battery cell. The linear drive module then drives the battery cell to the end of the lever, and under the drive of the first pneumatic linear drive module, the lever pushes the battery cell off the clamping part, achieving automatic unloading.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] Reference Figures 1 to 11 This utility model provides a technical solution: an automatic battery cell winding machine, including a support cabinet 1. The support cabinet 1 is equipped with a PLC control system and an air source system that provides power to the cylinder. The air source system is connected to the PLC control system. The PLC control system is used to control the entire automatic winding machine to operate according to the set path and is the control center of the entire equipment. From one end of the support cabinet 1 to the other end, there are a winding frame, a transmission device, a shearing mechanism, a winding mechanism and a pushing mechanism.
[0033] like Figure 1 As shown, an unwinding frame is provided at one end of the support cabinet 1. The unwinding frame includes a fixed base 16, which is located at the bottom of one end of the support cabinet 1 and connected to it. A frame 15 is vertically provided on the top of the fixed base 16. The frame 15 has multiple layers of support shafts 14, and the number of support shafts 14 corresponds to the number of layers of the battery cells. Typically, the battery cells include positive and negative electrode plates and a separator. The positive and negative electrode plates and the separator are all placed on the support shafts 14 in the form of rolls. One end of each support shaft 14 is rotatably connected to the frame 15. On the side of the frame 15 away from the support shafts 14, there are unwinding motors 12 corresponding to the support shafts 14. The unwinding motors 12 are connected to the support shafts 14, and the unwinding motors 12 will drive the support shafts 14 to rotate.
[0034] In order to fix multiple volumes, such as Figure 1 As shown, a baffle 13 is coaxially provided at the end of each support shaft 14 near the frame 15, and a fastening disc (not labeled in the figure) is threaded onto the end of the support shaft 14 away from the frame 15. When each roll is placed on the support shaft 14, it can be pressed and fixed by the fastening disc. In this way, when the unwinding motor 12 rotates, each roll can rotate and unwind at a certain speed without slipping.
[0035] Furthermore, a transmission device is installed on the top of the support cabinet 1, such as... Figure 1 As shown, the transmission device includes a support frame 9 set on the top of the support cabinet 1. A pneumatic linear lifting module 11 that extends downward is provided inside the top of the support frame 9. A first bearing frame 8 is horizontally provided below the pneumatic linear lifting module 11. A second bearing frame 17 is horizontally provided below the first bearing frame 8. The second bearing frame 17 is installed on the top of the support cabinet 1.
[0036] Belt conveyors are provided on the opposing surfaces of the first bearing frame 8 and the second bearing frame 17, such as Figure 5 As shown, the belt conveyor includes a conveyor belt 22 positioned below the first support frame 8 and above the second support frame 17. A first drive roller 40 is located at one end of the conveyor belt 22, with both ends of the first drive roller 40 rotatably connected to the second support frame 17 and the first support frame 8. One end of the first drive roller 40 is connected to a drive motor 41, which is mounted on the first support frame 8 and the second support frame 17 via motor frames. Here, the first drive roller 40 drives the conveyor belt 22. A second drive roller 21 is located at the other end of the conveyor belt 22, with both ends of the second drive roller 21 rotatably mounted on a slide block 38. The slide block 38 is slidably mounted on a slide rail 39. Figure 5 As shown, slide rails 39 are respectively located below the first support frame 8 and above the second support frame 17;
[0037] Each slide block 38 is provided with an adjusting screw 10 at the end away from the second drive roller 21. The end of the adjusting screw 10 is movably placed in the support 35. The support 35 and the adjusting screw 10 are connected by fasteners, which are nuts set on the adjusting screw 10. The support 35 is respectively set below the first bearing frame 8 and above the second bearing frame 17. When the nut on the adjusting screw 10 is turned, the adjusting screw 10 can drive the second drive roller 21 to move, so that the second drive roller 21 and the first drive roller 40 tighten the conveyor belt 22 more, preventing the conveyor belt 22 from slipping and running off-center.
[0038] like Figure 5 As shown, a support plate 25 is provided in the middle of each conveyor belt 22. The edges of the support plate 25 are connected to the first bearing frame 8 and the second bearing frame 17 respectively through the bracket 26. Both ends of the support plate 25 are curved, and the surface of the support plate 25 is smooth. Under the support of the support plate 25, the middle of each conveyor belt 22 protrudes outward. In actual use, the upper belt conveyor is placed on the lower belt conveyor under the drive of the second pneumatic linear drive module 27 to clamp the battery cell. That is, when the upper and lower conveyor belts 22 are in contact, the protruding positions of the conveyor belts 22 are in horizontal contact, and the battery cell is clamped by the protruding positions of the conveyor belts 22.
[0039] It should be noted that the upper and lower conveyor belts 22 are closely fitted to clamp the battery cell. Because the contact area of the conveyor belts 22 is large, the area of clamping the battery cell is also relatively large, so the battery cell will not be crushed. The rotation speed of the conveyor belts 22 corresponds to the unwinding speed of the unwinding motor 12. In this way, when the upper and lower conveyor belts 22 clamp the battery cell and move forward, no tension will be generated, thus avoiding the surface of the battery cell being torn.
[0040] Furthermore, the battery cells coming out of the transmission device need to be cut, so a cutting mechanism is provided at the end of the transmission device. The cutting mechanism includes a U-shaped frame 7 with the opening facing downward. A second pneumatic linear drive module 27 is provided inside the top of the U-shaped frame 7. A pressure plate 30 is provided parallel below the second pneumatic linear drive module 27.
[0041] A support plate 29 is provided parallel to the pressure plate 30 below it. The support plate 29 is connected to the U-shaped frame 7. Under the drive of the second pneumatic linear drive module 27, the pressure plate 30 is placed on the support plate 29, and the battery cell is placed on the support plate 29. Therefore, the battery cell is pressed and held still by the pressure plate 30. A U-shaped seat 33 is provided below the side of the U-shaped frame 7 near the winding mechanism. A third pneumatic linear drive module 34 is installed on the side of the U-shaped seat 33. The extension and retraction direction of the third pneumatic linear drive module 34 is vertically upward. A knife holder 32 is provided on the top of the third pneumatic linear drive module 34. A cutter 31 is detachably provided on the top of the knife holder 32. The cutter 31 and the knife holder 32 are fastened with bolts to facilitate the replacement of the cutter 31.
[0042] The most important part of the shearing mechanism is, for example, Figure 10 and Figure 11 As shown, the pressure plate 30 extends toward the clamping part 24, so that the pressure plate 30 and the bearing plate 29 are stepped, and the edge of the pressure plate 30 is tangential to the cutter 31. When the pressure plate 30 presses the battery cell, the cutter 31 is lifted by the third pneumatic linear drive module 34 to cut the battery cell.
[0043] Furthermore, a winding mechanism is provided at the end of the shearing mechanism. The winding mechanism includes a first frame 6, which is located on the top of the support cabinet 1. A drive motor 5 is provided on one side of the first frame 6. A pneumatic manipulator is installed at the end of the shaft of the drive motor 5. Clamping parts 24 are respectively provided on the two free ends of the pneumatic manipulator. Figure 7 As shown, the pneumatic manipulator includes a U-shaped mounting base 28, the opening of which faces the clamping part 24, and the middle part of the U-shaped mounting base 28 is connected to the end of the shaft of the drive motor 5.
[0044] The upper and lower ends of the U-shaped mounting base 28 are each equipped with a fourth pneumatic linear drive module 37. The extension and retraction direction of the fourth pneumatic linear drive module 37 is towards the inside of the U-shaped mounting base 28. The ends of the two clamping parts 24 are respectively connected to the ends of the fourth pneumatic linear drive module 37. The clamping parts 24 are opened or closed in parallel under the drive of the pneumatic manipulator. Specifically, the two clamping parts 24 are closed or opened under the drive of the fourth pneumatic linear drive module 37.
[0045] The first frame 6 is movable, that is, the bottom of the first frame 6 is slidably mounted on the guide rail 3 by a slider. A linear drive module 2 connected to the slider is provided on one side of the guide rail 3. The linear drive module 2 is a lead screw linear drive module or a linear motor. Both the guide rail 3 and the linear drive module 2 are located on the top of the support cabinet 1.
[0046] Furthermore, a pushing mechanism is provided on one side of the winding mechanism. The pushing mechanism includes a second frame 18, which is located on the top of the support cabinet 1. The top of the second frame 18 is provided with a first pneumatic linear drive module 19 that is parallel to the clamping part 24. A lever 23 is provided on the free end of the first pneumatic linear drive module 19.
[0047] like Figure 4 As shown, the lever 23 is perpendicular to the clamping part 24. When the battery cell stops at the end of the lever 23 under the drive of the linear drive module 2, the lever 23 pushes the battery cell to slide off the clamping part 24 under the drive of the first pneumatic linear drive module 19. The pushing mechanism is used to push the battery cell wound on the clamping part 24 off the clamping part 24 to achieve automatic unloading.
[0048] Based on the above implementation, the specific working process of this application is as follows: Figure 9 As shown, the linear drive module 2 drives the first frame 6 to move towards the U-shaped frame 7. At this time, the two clamping parts 24 are in the open state, that is, the linear drive module 2 drives the clamping parts 24 to move to the side of the shearing mechanism to wind the battery cell.
[0049] It should be noted that, as Figure 10 As shown, due to the stepped arrangement at the ends of the pressure plate 30 and the support plate 29, when the cutter 31 cuts the battery cell, a small section of the end of the battery cell will protrude outside the support plate 29. This highlights the importance of the stepped arrangement of the pressure plate 30 and the support plate 29, because the small section protruding outside the support plate 29 is used for clamping by the clamping part 24.
[0050] It should be noted that the shearing mechanism can not only cut the battery cell, but also limit the battery cell during winding. That is, when the clamping part 24 clamps the free end of the battery cell, as... Figure 10 As shown, the clamping part 24 travels a certain distance under the drive of the linear drive module 2, creating a gap between the clamping part 24 and the pressure plate 30. This prevents the clamping part 24 from contacting the pressure plate 30 when rotating, and also provides sufficient space for the battery cell winding. The clamping part 24 also clamps the battery cell to prevent it from slipping during winding. For example... Figure 10 As shown, at this time, the pressure plate 30 rises a certain distance under the drive of the second pneumatic linear drive module 27, creating a gap between the pressure plate 30 and the support plate 29. This gap is sufficient for the battery cell to pass through. For example... Figure 10 As shown, the clamping part 24 clamps the battery cell for winding, and at this time the pressure plate 30 presses and limits the battery cell;
[0051] After the battery cell has been wound to the preset number of turns, such as Figure 9As shown, the battery cell is clamped by the pressure plate 30, then the cutter 31 cuts the battery cell, and then the linear drive module 2 drives the battery cell to one side of the pusher mechanism, that is, the linear drive module 2 drives the clamping part 24 to one side of the lever 23, as shown. Figure 4 As shown, the battery cell movement lever 23 is at its end position at this time. Then, driven by the first pneumatic linear drive module 19, the lever 23 pushes the battery cell to fall off the clamping part 24.
[0052] like Figure 1 and Figure 4 As shown, a conveyor belt 4 is installed below the clamping part 24, allowing the battery cell to fall directly onto the conveyor belt 4 for forward transport. At this time, the two clamping parts 24 will act like... Figure 11 Open it again and repeat the above steps to repeat the winding process.
[0053] Based on the above implementation, it should be further explained that in order to allow the fourth pneumatic linear drive module 37 to rotate while being ventilated, a pneumatic slip ring 36 is coaxially installed on the shaft of the drive motor 5. The pneumatic slip ring 36 consists of a stator and a rotor. During installation, the rotor is fixed to the shaft, and the stator is set on the first frame 6. The rotor is connected to the fourth pneumatic linear drive module 37 through a pipe, while the stator is connected to the air source system through a pipe.
[0054] Furthermore, the air supply system is connected to the pneumatic linear lifting module 11, the first pneumatic linear drive module 19, the second pneumatic linear drive module 27, and the third pneumatic linear drive module 34, respectively.
[0055] Based on the above implementation, it should be further explained that the PLC control system is also electrically connected to the linear drive module 2, the unwinding motor 12, the transmission motor 41, and the drive motor 5, respectively, so as to control each motor to operate according to the approved path. Moreover, the unwinding motor 12, the transmission motor 41, and the drive motor 5 are servo motors, which facilitates precise control of angle and speed.
[0056] Based on the above implementation, it can be further optimized by providing two limiting rods 20 on the side of the support frame 9 near the unwinding frame, with a certain distance between the two limiting rods 20, and the distance is flush with the surface of the conveyor belt below. The two ends of the limiting rods 20 are rotatably connected to the support frame 9, and the layers of the battery cells coming from the support shaft 14 enter between the two conveyor belts 22 from between the two limiting rods 20.
[0057] Horizontal panels were also installed at the spacing (such as...) Figure 3 (As indicated by the middle arrow A), the plate is connected to the support frame 9, and the plate extends all the way to the support plate 25. This allows the battery cells that pass between the two limiting rods 20 to transition from the plate to the support plate 25, avoiding the battery cells from settling due to the large distance span. The two sides of the plate are connected to the support cabinet 1 through support rods.
[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
