Description

TECHNICAL FIELD

[0001] The utility model relates to product appearance detection field technology especially is a carousel product appearance detection machine. BACKGROUND

[0002] It is a relatively mature prior art to detect the appearance of products by using a CCD, and in order to improve the appearance detection efficiency of products, a carousel design is adopted, which is a relatively ideal design. For example, a glass carousel fly-pat detection equipment is disclosed in CN 111729863 A, which comprises a support cabinet, a double-track feeding vibration disc, a glass carousel and a guide mechanism. The double-track feeding vibration disc is arranged on the top of the support cabinet, and the double-track feeding vibration disc is provided with a vibration disc track. The glass carousel is arranged on the top of the support cabinet. The guide mechanism is arranged on the top of the support cabinet through a support. The guide mechanism is located between the height CCD mechanism and the vibration disc track. The support cabinet top is provided with a height CCD mechanism, a width CCD mechanism, a height defect collection box, a width defect collection box, a mixed material collection box and a good product collection box in the direction of rotation of the glass carousel. The height CCD mechanism, the width CCD mechanism, the height defect collection box, the width defect collection box, the mixed material collection box and the good product collection box are distributed along the circumference of the glass carousel.

[0003] Now the shape size and surface appearance of products (such as whether the surface is damaged, has stains, gum stains, etc.) need to be detected. The above-mentioned detection equipment can only detect the size of the product, that is, another detection equipment needs to be used to detect the surface appearance of the product. The turnover of the product during detection and the storage of multiple equipment in the workshop are not conducive to the control of production cost.
