Secondary detection device for plastic nuts

Abstract

The invention relates to the field of plastic nuts, in particular to a secondary detection device for plastic nuts. The technical problem of the invention is to provide the secondary detection device for the plastic nuts. The secondary detection device for the plastic nuts comprises a bottom plate assembly, a cleaning unit, a thread on-off detection unit, a thread damage detection unit and a control screen; the bottom plate assembly is connected with the cleaning unit; and the bottom plate assembly is connected with the thread on-off detection unit. According to the secondary detection device for the plastic nuts, secondary cleaning of the plastic nuts and primary detection of the threads of the plastic nuts are achieved, meanwhile, secondary detection of the plastic nuts which have slight damage to the threads of some plastic nuts and can achieve certain functions is achieved, unqualified plastic nuts are removed one by one, the product quality is greatly improved, potential safety hazards existing in the using process are reduced, and life and property safety is improved.

Description

technical field [0001] The invention relates to the field of plastic nuts, in particular to a secondary detection device for plastic nuts. Background technique [0002] Plastic nut is a branch of various nuts. Its role is to cooperate with bolts to achieve the purpose of combining two or more parts. Compared with ordinary metal nuts, the biggest advantage of plastic nuts is its good insulation performance. In addition, because of the non-metallic manufacturing, under the influence of current or other electrical signals, there will be no signal interference such as eddy current, and its anti-interference performance is somewhat suitable for communication and other industries. [0003] However, since plastic nuts are ordinary plastic products, the torque and strength of the nuts are not as good as ordinary metal nuts. If the torque is too large, the teeth may slip or the head may break. Therefore, the inspection before use is particularly important. At present, the inspection ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the fact that plastic nuts are ordinary plastic products, the torque and strength of the nuts are not as good as ordinary metal nuts, and the teeth may slip or the head may break if the torque is too large, so the detection before use is particularly important. At present, the detection of plastic nuts is manual. Operation, manual inspection cannot achieve the consistency of inspection standards for some nuts with dirty threads, and it is prone to false inspections, missed inspections and other phenomena that affect product quality, and some plastic nuts have slight damage to the threads and can achieve certain functions. Manual operations cannot be eliminated one by one, which will easily lead to product quality and safety, thus causing potential safety hazards that threaten the safety of life and property. The technical problem of the present invention is to provide a secondary detection device for plastic nuts
