[0002] Bottle caps are an important part of food and beverage packaging. They have the function of keeping the contents of the product sealed, and also have the function of preventing theft and opening, as well as safety. They are widely used on bottled products. After the bottle cap is produced, its appearance needs to be inspected, including the inner circle thread, the outer wall friction pattern and the trademark pattern on the back. Whether the appearance of the bottle cap meets the standard affects the sealing effect of the product. It needs to be fully inspected before it can be installed on the bottled product for shipment. In the prior art, the inspection of bottle caps usually adopts the manual inspection method, that is, manual inspection of the appearance of the product at all locations.
