Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a track cleaning device for products with special-shaped surfaces. Background Art

[0002] After the mobile phone back shell product is assembled, it is necessary to inspect the product for damage before shipment. Due to environmental and process factors, there will be dust and residual glue on the surface of the product, which will mislead the product into being damaged during the inspection, thus feeding back some untrue data. Therefore, the product will be cleaned before entering the inspection to remove dust and residual glue. Usually, a rubber-coated grinding head and a dust-free cloth are used to wipe and clean the surface of the product. The grinding head moves in a circle driven by the motor, and the product moves in a straight line on the linear module. The mechanical components cooperate to achieve cleaning while the product is moving, so that clean materials can enter the AOI for inspection.

[0003] However, the traditional cleaning method only uses simple circular wiping movements. When encountering special-shaped products (such as the convexity of the back cover of a mobile phone), the convex structure makes it difficult for the grinding head to clean the specified position, and there is a blind spot in the cleaning, which affects the cleaning performance of the mobile phone back cover product and further affects the accuracy of the subsequent AOI inspection results.
