Technical Field
[0001] The utility model relates to the field of detection and adjustment devices, in particular to a forward and reverse detection and adjustment device for a nut. Background Art
[0002] With the widespread promotion of Industry 4.0, which aims to elevate the level of intelligence in the manufacturing industry and establish adaptable, resource-efficient, and ergonomically oriented smart factories, intelligent assembly lines have become essential for companies to enhance their core competitiveness, leading to their widespread adoption. Within this context, automation and intelligent manufacturing are responding to this call, eliminating inefficient, labor-intensive manual operations.
[0003] In an automated production line, ensuring that each nut is in the correct direction can reduce errors in the assembly process, reduce rework and repair time, and thus improve overall production efficiency. The front and back sides of the nut may have differences in shape or thread. If the direction is wrong during assembly, the threads may not engage correctly, affecting the firmness and stability of the connection, thereby reducing product quality. In order to ensure the consistency of the front and back sides of the nut in the production line, it is generally necessary to manually observe with the naked eye, pick out the nuts with the wrong front and back sides, flip them to the correct side, and then place them on the production line. This makes the front and back adjustment of the nut less efficient and the labor cost higher. Utility Model Content
