The wax flake collection mechanism is located on the upper part of the mounting plate, the separator film laying mechanism is located on the lower part of the mounting plate, the separator unwinding mechanism is located on the middle left side of the mounting plate, there are multiple support rollers, which are respectively located at the upper left corner, upper right corner, and lower right corner of the mounting plate, the vision inspection system is located between the support rollers at the upper left and upper right corners, and the gravity roller is located to the left of the support roller at the lower right corner and is higher than the support roller at the lower right corner."

[0004] Existing automatic winding and collecting devices for battery core separators typically use a fixed spacing between the winding shafts, which cannot be adjusted according to actual conditions. This results in the separator roll being difficult to remove from the winding shaft after winding due to its tension, easily causing damage to the separator and increasing operational difficulty. Secondly, the removal of most separator cores on the market is done manually. This method is not only inefficient but also prone to instability, making it difficult to meet the needs of automated production.

[0005] Therefore, an automatic winding and collection device for battery core separators is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an automatic winding and collecting device for battery core separators. This device effectively relieves the tension of the separator, allowing the separator roll to be easily removed from the winding rod, preventing separator damage and improving work efficiency.

The collecting assembly includes a winding motor fixedly connected to the worktable, a turntable fixedly connected to the output end of the winding motor, a receiving groove opened at one end of the turntable, an adjusting disc fixedly connected to the inner surface of the receiving groove, a rotating seat rotatably connected to one end of the adjusting disc, a micro motor installed on one inner wall of the receiving groove, the output end of the micro motor fixedly connected to the rotating seat, two connecting rods rotatably connected to the inner surface of the rotating seat, an adjusting block rotatably connected to one end of each of the two connecting rods, two through slots opened at one end of the adjusting disc, two adjusting blocks slidably connected to the two through slots respectively, and a winding rod fixedly connected to one end of each of the two adjusting blocks.

[0008] Preferably, both adjustment blocks are in the shape of an "I" and are mirror images of each other.

[0009] Preferably, the two connecting rods are the same size and both connecting rods are "L" shaped.

[0010] Preferably, the unloading device includes a displacement cylinder fixedly connected to the workbench, a movable frame fixedly connected to the output end of the displacement cylinder, an electric slide rail mounted on the top of the movable frame, a slider slidably connected to the outer surface of the electric slide rail, and an unloading frame mounted on the top of the slider.

[0012] Preferably, the bottom end of the movable frame is fixedly connected to two slide bars, and the top end of the worktable is provided with a slide groove that cooperates with the two slide bars.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 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.

[0029] like Figures 1 to 6 As shown, this utility model provides an automatic winding and collecting device for battery core separators, including a workbench 1, a collecting component 2 installed on one side of the workbench 1, and an unwinding device 4 installed on the top of the workbench 1.

[0030] The collecting component 2 includes a take-up motor 3 fixedly connected to the workbench 1. A turntable 21 is fixedly connected to the output end of the take-up motor 3. A receiving groove 22 is formed at one end of the turntable 21. An adjusting disc 24 is fixedly connected to the inner surface of the receiving groove 22. A rotating seat 243 is rotatably connected to one end of the adjusting disc 24. A micro motor 23 is installed on one inner wall of the receiving groove 22. The output end of the micro motor 23 is fixedly connected to the rotating seat 243. Two connecting rods 242 are rotatably connected to the inner surface of the rotating seat 243. One end of each connecting rod 242 is rotatably connected to... The adjusting block 241 and the adjusting disk 24 have two through slots 244 at one end. The two adjusting blocks 241 are slidably connected to the two through slots 244 respectively. One end of each adjusting block 241 is fixedly connected to a winding rod 25. Through the cooperation of components such as the winding motor 3, the turntable 21 and the adjusting disk 24, the micro motor 23 can drive the rotating seat 243, and the spacing of the winding rod 25 can be flexibly adjusted through the connecting rod 242 and the adjusting block 241, so that the diaphragm roll can be easily removed from the winding rod 25, avoiding damage to the diaphragm and improving work efficiency.

[0031] Specifically, both adjusting blocks 241 are in the shape of an "I" and are mirror images of each other. The "I" shaped adjusting blocks 241 can fit tightly with the through slots 244 of the adjusting disc 24. While ensuring that the adjusting blocks 241 slide stably along the through slots 244, the stability of their connection with the connecting rod 242 is enhanced, ensuring the stability of the winding rod 25 adjustment process and preventing the diaphragm from shifting or slipping during winding.

[0032] like Figures 1 to 6 As shown, the two connecting rods 242 are the same size and both are L-shaped. The L-shaped connecting rods 242 with the same size can realize synchronous and equidistant adjustment of the adjusting block 241 under the drive of the rotating seat 243, ensuring the consistency of movement of the two winding rods 25, so that the diaphragm roll is subjected to uniform force during the winding process and improving the winding quality.

[0033] Furthermore, the unloading device 4 includes a displacement cylinder 42 fixedly connected to the workbench 1. The output end of the displacement cylinder 42 is fixedly connected to a movable frame 41. An electric slide rail 45 is installed at the top of the movable frame 41. A slider 43 is slidably connected to the outer surface of the electric slide rail 45. An unloading frame 44 is installed at the top of the slider 43. The unloading device 4, consisting of the displacement cylinder 42, the electric slide rail 45, and the slider 43, can achieve precise positioning and movement of the unloading frame 44 in three-dimensional space. It can quickly and stably approach and grab the diaphragm roll. Compared with manual unloading, it significantly improves the unloading efficiency and automation level.

[0034] like Figures 1 to 6As shown, the unloading frame 44 is U-shaped. The U-shaped unloading frame 44 can grip the diaphragm roll from both sides, so that the diaphragm roll is subjected to uniform force during the gripping process, effectively avoiding damage to the diaphragm due to excessive local force. At the same time, it is convenient to unload and transfer the diaphragm roll from the winding rod 25 stably.

[0035] It is worth noting that two slide bars 461 are fixedly connected to the bottom of the movable frame 41, and a slide groove 46 is provided at the top of the worktable 1 to cooperate with the two slide bars 461. The cooperation between the slide bars 461 and the slide groove 46 provides guidance and support for the movement of the movable frame 41, reduces the shaking and deviation of the movable frame 41 during the movement, ensures that the unloading frame 44 can be accurately moved to the designated position, and improves the stability and reliability of the unloading device 4.

[0036] The winding motor 3 and the micro motor 23 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0037] Working principle and process: When using this automatic battery core separator winding and collecting device, the winding motor 3 starts, driving the turntable 21 to rotate, causing the winding rods 25 to wind the separator. When the separator needs to be removed after winding, the winding motor 3 adjusts the two winding rods 25 to a suitable angle. Then, the micro motor 23 starts, driving the rotating seat 243 to rotate. The rotating seat 243 drives the two "L"-shaped connecting rods 242 to move, thereby causing the "I"-shaped adjusting block 241 to move in the through slot 2 of the adjusting plate 24. The 44 slides inward to adjust the spacing of the take-up rod 25. Then, the displacement cylinder 42 works to push the moving frame 41 to move along the slide groove 46 on the worktable 1. At the same time, the moving frame 41 drives the unloading frame 44 to move to one side of the diaphragm roll. Then, the electric slide rail 45 is activated. The electric slide rail 45 drives the slider 43 and the unloading frame 44 to slide on the moving frame 41, so that the unloading frame 44 can drive the diaphragm roll to move, unload the diaphragm roll from the take-up rod 25 and transfer it to the designated position, completing the entire process of automatic winding and collection of the diaphragm.
