Description

Technical Field

[0001] The present invention belongs to the technical field of machinery, and relates to a fully automatic cleaning and detection device, in particular to a material thickness detection and cleaning system and its operation method. Background Art

[0002] During the processing and manufacturing of electronic products, it is necessary to clean processing waste chips, residual liquid, etc., and thickness detection is also required before subsequent processing, so as to avoid defective products occupying production resources, resulting in waste and increased production costs. Only by ensuring the cleanliness and thickness standard of the raw materials can the accuracy and good effect of subsequent processing be guaranteed. In the prior art, manual cleaning operations and thickness detection are usually adopted, but manual cleaning and detection have the following problems:

[0003] 1. Manual operation has low efficiency, prolongs working hours and reduces output; it consumes a large amount of manpower and increases costs;

[0004] 2. The environment of blowing water and dry ice cleaning is not conducive to long-term manual operation and affects human health;

[0005] 3. Manual operation is prone to incomplete cleaning, affecting the quality of subsequent processing and increasing defective products;

[0006] 4. The accuracy of manual thickness detection is low, the precision is poor, and the detection standard is difficult to unify, resulting in large errors in detection results.

[0007] 5. Manual operation is prone to cause risks of three types of injuries to products.

[0008] To solve the above technical problems, for example, a cleaning device for fixture finished products has been disclosed in Chinese patent literature [Chinese Patent No.: 202020778417.1]. The present utility model discloses a cleaning device for fixture finished products, specifically relating to the technical field of cleaning fixture finished products, including a brush plate, an air wheel is arranged on the inner wall of the cavity, an air outlet hole is arranged at the right end of the cavity, a rotating shaft is fixedly installed on the inner wall of the air wheel, bearings are arranged at both ends of the air wheel, the bearings are fixedly installed on the inner wall of the brush plate, a wooden board is fixedly installed at the bottom end of the rotating shaft, a wet sponge is fixedly installed at one end of the wooden board, a dry sponge groove is arranged at the top of the brush plate, a dry sponge is fixedly installed on the inner wall of the dry sponge groove, a dry sponge groove is arranged at the top of the cavity, and a dry sponge is fixedly installed on the inner wall of the dry sponge groove. The present utility model can inject water and gas into the water pipe and the air pipe respectively. The water will be sprinkled on the surface of the product through the nozzle, then the gas will blow the air wheel through the air outlet hole, then the air wheel drives the rotating shaft to rotate, and the rotating shaft drives the wet sponge on the wooden board to rotate, so that the rotating wet sponge will wipe the surface of the product.

[0009] In the above technical solution, only the cleaning of the product surface can be achieved through water spraying and air jetting, and targeted internal cleaning cannot be performed. Especially for shell electronic products with a rotating shaft, the inner hole of the rotating shaft forms a cleaning blind area, which affects subsequent processing due to the inability to clean thoroughly, resulting in an increase in the defective rate of the finished product and a reduction in the quality of the finished product.
