Problems solved by technology
After collecting the images of the back side, the front side (or the back side) and the left side (or the right side), it is necessary to rotate to another detection position before performing the rear side (or front side) and the right side (or Left side) image collection, so the existing mobile phone appearance detection system based on machine vision has the disadvantage of long detection cycle, which leads to low detection efficiency

Embodiment Construction
[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0039] In view of the disadvantages of too many or too few cameras in the existing mobile phone appearance inspection device, the inventor of the present invention plans the scanning path for the area to be inspected by the mobile phone, and determines the number of multi-station parallel product appearance inspection systems according to the number of planned paths. The structure and the number of cameras used, each camera performs continuous scanning according to th...

The invention discloses a multi-station parallel product appearance inspection system, which comprises a workbench, a support frame, and a rotating device partly extending to the support frame and fixed to the workbench. The first positioning device is fixed on the rotating device, and is located in the space formed by the support frame when detecting the product to be detected. The back detection device and two side detection devices suspended on the support frame, after receiving the control signal from the main controller, the back detection device and the two side detection devices respectively carry out inspection on the back and side of the product to be inspected along the set route. Image Acquisition. The technical solution in this application can greatly improve the detection efficiency of the detection system.
Description
technical field [0001] The invention relates to the field of electro-optical device detection, in particular to a multi-station parallel product appearance detection system. Background technique [0002] During the manufacturing process of injection molding products, defects such as stains, scratches, and particles will appear on the surface of the product. Electronic products such as mobile phones and digital cameras have extremely high requirements on appearance, such as surface defects are not allowed. At present, the surface inspection of the appearance of electronic products in China mainly relies on manual inspection with naked eyes. Due to the subtle differences in the characteristics of defects, coupled with the limitations of the materials used and the lighting conditions in the workshop, some defects are difficult to distinguish from the background. Workers need to repeatedly adjust the observation angle to find them. Cause false detection and missed detection. ...
