Workpieces often require cleaning of surface contaminants during or upon completion of the production process. For example, the requirement for cleaning an electronic product is higher, cleanliness of some components of the electronic product often has a great influence on use, and for example, surface cleanliness of a lens of the electronic product often affects definition of an image or a video obtained by shooting the electronic product.

Referring to fig. 1, the following description will take the cleaning of the lens 210 on the component 200 that may be involved in the production process of the electronic product as an example. Currently, the requirement for cleanliness of the surface of the lens 210 is higher and higher, for example, the requirement for the diameter of particles on the surface of the lens 210 to be less than 0.01mm²Or the length of the fibrous impurities is less than 1mm and the width is less than 0.01mm, or even the surface of the lens 210 is required to be absolutely impervious to dirt, dust and other impurities which affect the imaging. In some embodiments, the number of lenses 210 on the subassembly 200 may be three, and in other embodiments, the number of lenses 210 may be greater or fewer. Referring to fig. 2(a), in some embodiments, the lens 210 has a concave structure 220 after being mounted on the component 200, the corners of the concave structure 220 are prone to contain impurities, so that the cleaning effect may not be ideal, and the cleaning of the lens 210 having the concave structure 220 is more complicated and the cleaning is more complicatedThe difficulty is higher, and the existing wiping means cannot clean the lens 210 well. In some embodiments, the lens 210 has a concave structure 220 on both the upper and lower surfaces, as shown in fig. 2(B), the lens with such a concave structure is often difficult to clean, and requires multiple cleaning methods to cooperate, otherwise it is difficult to effectively remove impurities on the surface of the lens.
