Description

Technical Field

[0001] This utility model relates to the field of appearance inspection technology, and in particular to an appearance inspection and sorting machine. Background Technology

[0002] Appearance inspection is a detection method that uses machine vision technology to automatically identify defects on the surface of products. This method acquires product surface information through image acquisition equipment and combines it with algorithms to analyze defect features such as foreign objects, scratches, and stains. Compared with traditional visual inspection, it has technical advantages such as high detection efficiency, strong stability, and adaptability to the needs of automated production lines.

[0003] To this end, patent CN217191000U discloses an online sorting machine for detecting product appearance defects, including a base plate, a support leg fixedly connected to the bottom of the base plate, a housing fixedly connected to the top of the base plate, a detection head disposed inside the housing, a top plate fixedly connected to the top of the housing, and an adjustment assembly fixedly connected inside the housing. The adjustment assembly includes two fixed seats fixedly connected inside the housing. In use, the phone case is placed on the detection table, and starting the motor drives the right-side pulley to rotate. Since the belt connects to the outer surfaces of the two pulleys, both pulleys rotate simultaneously. The rotation of the pulleys drives the threaded rod to rotate, causing the threaded block to move downwards. The downward movement of the threaded block causes the connecting rod and the detection head to move downwards. The height of the detection head can be adjusted according to the size of the characters on the outer surface of the phone case. A lighting lamp can be turned on when the light is dim.

[0004] Existing appearance inspection and sorting machines have poor protection for the inspection head during use. When the inspection head is not in use, it is easily damaged when exposed, which affects its service life. Utility Model Content
