Description

Technical Field

[0001] This utility model mainly relates to the technical field of removing QR codes during battery rework, specifically a dust-free cloth winding device. Background Technology

[0002] Consumer batteries refer to battery products used in various consumer electronic products to provide them with power. The main types include primary batteries and secondary batteries. Primary batteries, also called primary batteries, cannot be restored by recharging after their chemical energy is converted into electrical energy. They must be discarded after the energy is depleted. Common examples include alkaline batteries and zinc-manganese batteries. Secondary batteries are rechargeable batteries that can be used repeatedly by recharging, realizing the mutual conversion of chemical energy and electrical energy. Common examples include nickel-metal hydride batteries and lithium-ion batteries. Lithium-ion batteries have advantages such as high energy density, low self-discharge rate, and no memory effect, and are widely used in various portable consumer electronic products such as mobile phones, laptops, tablets, and digital cameras.

[0003] During the rework process of defective products generated in the production of consumer batteries, the original QR codes need to be removed and reprinted. The removal of the original QR codes is mostly done manually, using non-woven fabric to wipe them off. The non-woven fabric needs to be replaced frequently. It is difficult to control the force evenly when using manual labor, and some areas may not be completely wiped off, resulting in overlapping or blurry old and new QR codes, which increases the probability of misreading by the scanning equipment. In addition, manually wiping the battery surface one by one requires frequent replacement of non-woven fabric, which cannot meet the high-speed requirements of automated production lines and slows down the overall rework efficiency. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic. Specifically, this utility model provides a cleanroom cloth winding device to solve the technical problem mentioned in the background that currently, during the rework of defective products, workers often manually replace the non-woven fabric, which, due to the frequent need for replacement, cannot meet the high-speed requirements of automated production lines.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A cleanroom wipe winding device includes a base plate and a three-axis moving module located on the base plate. The output end of the three-axis moving module is provided with a frame structure, and a winding mechanism is provided within the frame structure. The winding mechanism includes an unwinding shaft, a winding shaft, and a winding servo motor. The unwinding shaft and the winding shaft are distributed in parallel.

The output end of the winding servo motor is provided with an extension shaft and a winding active synchronous pulley on the extension shaft. The winding active synchronous pulley is connected to a winding driven synchronous pulley via a synchronous belt, and the winding driven synchronous pulley is located on the winding shaft.

[0008] Furthermore, both the unwinding shaft and the winding shaft are provided with bearing seats, and the two bearing seats are located in the circular holes on the mounting plate. The mounting plate and the winding servo motor are connected by bolts.

[0009] Furthermore, a spacer and a spring are provided on the portion of the unwinding shaft located within the frame structure, with the spring pressing against one side of the spacer. A tension control nut is provided at one end of the spring, which compresses the spring.

[0010] Furthermore, the mounting plate is provided with a measuring mechanism, which includes a winding length sensing wheel and a sensor mounting base. The nonwoven fabric body passes around the winding length sensing wheel. The winding length sensing wheel is provided with a scale, and the sensor mounting base is provided with a sensor body.

[0011] Furthermore, a timing belt tensioner is provided on the timing belt between the winding drive timing belt pulley and the winding driven timing belt pulley.

[0024] The above structure enables automatic replacement of non-woven fabric during the automatic erasure of the original QR codes on defective consumer batteries.
