Background

With the popularization of automatic production, products need to be detected before delivery, most products have high requirements on appearance, and taking a mobile phone middle frame as an example, the appearance detection of the mobile phone middle frame is a very important ring before delivery. The detection mechanism in the prior art is usually a high-precision detection camera, and the high-precision detection camera has higher requirements on the surface cleanliness when carrying out appearance detection on products, and the actual products are inevitably stained with various dirty substances in the production process, such as machine tool cutting fluid, lubricating oil, residual glue left by a protective film, fingerprints, dust and the like. Because the dirt is various and has no fixed form, the dirt is likely to be misjudged as a defect by the detection camera if the dirt is not treated before detection.

In view of the above, a wiping device is typically used to clean the surface of the product prior to appearance inspection of the product. The wiping device in the prior art generally comprises a motor, an eccentric wheel arranged at the output end of the motor, a wiping head connected to the eccentric wheel and dust-free cloth positioned at the end part of the wiping head and capable of being conveyed along the horizontal direction, wherein the wiping head can press the dust-free cloth on a product to be cleaned, the eccentric wheel is driven by the motor to rotate, so that the reciprocating motion of the wiping head is realized, and the dust-free cloth cleans the product to be cleaned. However, the above-described wiping device generally has the following problems when in use: 1) The wiping frequency is low, and is influenced by the eccentric wheel transmission structure, if the running frequency of the motor is increased, larger noise pollution is caused, and the trouble is caused to production line operators; 2) The wiping effect is bad, and in the wiping process, the wiping head reciprocates along with the eccentric wheel structure, and the dust-free cloth only depends on the friction force between the wiping head and the dust-free cloth to do short-distance displacement, so that the wiping head and the dust-free cloth can not keep relatively static, and the upper part of the product to be cleaned can not be cleaned.
