Description

Technical Field

[0001] The present application relates to the technical field of cleaning processing of 3C electronic products, and in particular to a glue erasing cleaning device and a cleaning method thereof. Background Art

[0002] In the field of 3C electronic product production, as people's demand for electronic products such as mobile phones, televisions, and tablets is growing, manufacturers need more efficient and convenient processing equipment to continuously replace manual operations, thereby improving their processing efficiency and quality. In the production process of 3C electronic products, it is necessary to clean the product's shell, screen and other structures to reduce the impact of dust and residual glue. Special automated cleaning equipment is often required to replace manual cleaning.

[0003] However, the traditional cleaning equipment cleaning method is to use a simple device to drive the cleaning tool to rotate and move back and forth. Although this cleaning method is simple, it requires more position driving structures and the manufacturing cost will also increase. If the position driving structure is reduced, the area of ​​rotation and cleaning of the cleaning tool will be greatly limited, and only a smaller area can be cleaned. In addition, the surface of some 3C products needs to be rubbed repeatedly to effectively clean some stubborn stains. Therefore, whether a wiping device with a rubbing effect is needed, rather than just contact and friction cleaning of the surface with a wiping cloth.

[0004] When using the equipment for cleaning, a cleaning cloth soaked in alcohol is required, but the cleaning cloth needs to be loaded and unloaded in time during use to ensure continuous cleaning. When replacing the cleaning cloth, the existing cleaning equipment needs to disassemble and assemble the loading structure, and the disassembly and assembly process is often not convenient. In addition, the loading structure often cannot adapt to cleaning cloths of different widths, so the compatibility is relatively low.

[0005] For example, a Chinese patent with the patent number CN107369608B discloses a wiping mechanism. The application uses a first pressing component that can be driven to move up and down and is provided with a movable wiping head; a wiping material component is provided with a fixed frame on which a strip of wiping material is wound; the first pressing component can be driven to press the movable wiping head against the wiping material against the surface of the workpiece to be cleaned, but this solution cannot imitate manual manipulation to perform clockwise and counterclockwise rotational wiping, and cannot achieve an ideal cleaning effect for products that require repeated rubbing.

[0006] For example, a Chinese patent with patent number CN109174525A discloses a glue erasing device, in which the driving part can control the movement of the clamping surface and enable the erasing tape to fit the side wall of the needle to be erased. During operation, the needle to be erased is placed between the erasing tapes. After the driving part controls the clamping surface to clamp, the erasing tapes fit and clamp the needle in the middle; then the needle is controlled to move axially away from the erasing tape, thereby achieving glue erasing. However, this solution cannot imitate manual rotary rubbing cleaning, nor can it change the rubbing scheme clockwise and counterclockwise. Therefore, it cannot complete the comprehensive cleaning of 3C products with higher requirements. Summary of the invention
