Description

Technical Field

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

[0002] Battery winding machines can wind positive and negative electrode sheets, separators, etc. into battery cells in a specific order and manner. By precisely controlling tension, speed and alignment, they ensure that the battery cell structure is compact and the dimensions are accurate, thereby improving battery performance and stability. At the same time, they have efficient automated production capabilities, reducing manual intervention and improving production efficiency and product consistency. They are key core equipment in battery manufacturing.

[0003] Existing battery winding machines suffer from the problem of slow and inefficient adjustments. Due to the lack of a convenient adjustment mechanism, it's difficult to quickly calibrate parameters when there are minor changes in raw material thickness or tension, or when the equipment vibrates during operation. This can easily lead to misalignment or displacement of the positive and negative electrode sheets and separator during winding, affecting the regularity of the cell structure, thereby reducing battery capacity, cycle life, and other performance characteristics, and even creating safety hazards. Furthermore, frequent shutdowns for adjustments significantly reduce production efficiency.

[0004] Therefore, this application provides a winding machine for battery production to meet the demand. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a winding machine for battery production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a winding machine for battery production, comprising a base and a processing table placed on top of the base, and further comprising:

[0007] A feeding assembly includes a fixed base fixed to the top of the processing table, a connecting platform fixed on the fixed base, a second drive motor mounted on the connecting platform, a feeding shaft rotatably mounted in the middle of the second drive motor, feeding shafts sleeved on each feeding shaft, slots formed on the outer sides of each feeding shaft, spring pieces mounted on each feeding shaft through the slots, a second damping spring mounted on the side of each feeding shaft away from the spring pieces, and fixing plates mounted at both ends of each feeding shaft, each fixing plate having slots, and an outward expansion plate mounted on the fixing plate through the slots.

[0009] Furthermore, a fixing platform is fixed to the top of the fixing base on the side away from the connecting platform, and a snap-fit ​​ring is rotatably provided on the top of the fixing platform.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the fixed base supports the fixed platform, and the rotating snap ring on the top of the fixed platform can be flexibly adjusted to snap the feeding shaft, ensuring that the feeding shaft is installed firmly and improving the stability and ease of operation of the feeding assembly.

[0011] Furthermore, a winding assembly is provided on the processing table. The winding assembly includes a lifting slot formed on the outside of the processing table. A sliding block is slidably disposed inside the lifting slot. First connecting plates are fixed on both sides of the processing table. A first guide rod is disposed between the first connecting plates. The first guide rod is disposed on the sliding block.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the lifting slot on the outside of the processing table provides a sliding track for the sliding block, which can move up and down along the slot. The first connecting plates on both sides of the processing table fix the first guide rod, which passes through the sliding block to ensure that the sliding block remains horizontally stable and without deviation when it is raised or lowered.

[0013] Furthermore, a lead screw is provided inside the lifting slot, a first drive motor is provided at the top of the lead screw, and a winding rod is provided between the sliding blocks.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the lead screw in the lifting slot is driven to rotate by the first drive motor at the top, which drives the sliding block to rise and fall along the slot, and the winding rod between the sliding blocks moves accordingly, so as to achieve precise adjustment of the winding height and ensure neat and stable winding.

[0015] Furthermore, the clamping assembly includes a telescopic rod fixed to the bottom of the processing table, a lower pressure plate fixed to the bottom of the telescopic rod, a first damping spring provided at the bottom of each lower pressure plate, a second connecting plate provided at the bottom of each first damping spring, a slot provided at the bottom of the lower pressure plate, and anti-damage rollers provided through the slot on the lower pressure plate.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the telescopic rod is fixed to the bottom of the processing table, and the lower pressure plate is raised and lowered by the telescopic movement to realize the clamping and release of the material. The anti-damage roller at the bottom of the lower pressure plate is embedded in the slot and can roll along the material surface to reduce the frictional resistance during clamping and avoid scratching the material surface. The first damping spring connects the lower pressure plate and the second connecting plate, providing elastic buffer during clamping to prevent excessive pressure from causing material deformation or damage, while adapting to changes in material thickness.

[0017] Furthermore, a second guide rod is provided on the top side of the processing table away from the cleaning assembly.

[0020] 1. The fixed base serves as the basic support, firmly fixed to the top of the processing table, and supports the connecting table. The second drive motor on the connecting table provides power to drive the feeding shaft, which is rotated in the middle, to realize the material conveying. The outer side of the feeding shaft is grooved with a spring sheet, which can provide elastic support and adapt to the deformation of the material during winding. The second damping spring on the side away from the spring sheet can buffer external force and adjust the feeding tension to avoid the material being too tight or too loose. The fixed plates at both ends of the feeding shaft have slotted expansion plates, which can flexibly adjust the position of the expansion plates. Together with the spring sheet and damping spring, the size of the roll can be precisely adjusted.

[0021] 2. The fixing block is fixed to the top of the processing table to provide support for the grinding wheel. After the third drive motor starts, it drives the outer gear to rotate, which in turn drives the grinding wheel to rotate. The grinding grooves on its surface come into contact with the material, and through friction grinding, waste and impurities on the material surface are effectively removed.
