Screw and nut optical image detection and screening machines were commonly used in the automotive screw standard industry in the early years. In recent years, with the improvement of manufacturing automation, more and more applications in the field of electrical appliances manufacturing and mobile phones, as well as some needs The automatic screw machine places higher requirements on the quality of the screws, and each screw or nut must be qualified to ensure a high degree of automation.

Screw optical screening machine, nut optical image inspection machine is a relatively mature and standardized automatic full inspection equipment. Generally, the selected inspection machines include glass plates, index plates, etc., depending on the shape of the nut and the different inspection requirements Flexible selection of suitable equipment.

Screw inspection items include: thread major diameter, thread minor diameter, pitch, pitch, thread length, head and neck, head thickness, cut tail, hexagonal size, characters, 360-degree defect detection, electroplating detection, cross groove, slotted groove Detection of plugging impurities, Y-groove and other defects.

Nut inspection items include: hexagonal size, height size, thread presence or absence, thread depth, large nut tooth damage, outer surface bump defect, lock nut defect detection, welding nut defect detection, etc., knurled nut defect size detection Wait.

The optical image inspection and screening machine can flexibly choose the camera lens configuration according to the user's inspection needs. The general equipment can be equipped with 1 to 6 industrial cameras to detect a variety of defect types. The company can recommend suitable optical screening machines according to the actual needs of users. For example, there are fewer types of defects to be detected, and single-camera inspection equipment can be selected. The equipment design is flexible and cost-effective.
