Screw sorting method

Abstract

The invention relates to a screw sorting method. The screw sorting method is characterized by comprising the following steps: a camcorder lens, a touch screen, a first photoelectric switch, a second photoelectric switch, a controller, a sorting pipeline, a scale plate in the sorting pipeline, a belt conveyer, a material receiving mechanism located at the discharging end of the sorting pipeline, and other devices are equipped; the information of the length of sorted screws and the sorting relationship are input into the touch screen, and the sorted screws are conveyed to the belt conveyer; the controller is used for receiving the changed signals of the first photoelectric switch; the camcorder lens is used for taking photographs for the sorted screws entering the scale plate and sending the photographs to the controller; the controller is used for receiving the changed signals of the second photoelectric switch; the controller is used for controlling the rotating position of the material receiving mechanism, so that the sorted screws fall into the material receiving mechanism. Through the adoption of the method, the time can be saved, the efficiency can be improved, the error rate can be reduced, and the automation requirement for automatic assembly can be met. The sorting method is suitable for sorting the mixed screws of different lengths.

Description

technical field [0001] The invention relates to a screw classification method. Specifically, it is a screw sorting method for sorting mixed screws of different lengths. Background technique [0002] In automated industrial production, it is often necessary to use screws of various lengths for automatic assembly. Due to various reasons, screws of different lengths are sometimes mixed together, which is difficult to provide for the automatic assembly system, seriously delaying the production process. At present, the classification of screws of different lengths mixed together is still a method of visual identification and manual sorting. Although the classification of screws can be achieved by visual identification and manual sorting, it is time-consuming, laborious, inefficient, and has a high error rate, which makes it difficult to meet the automation requirements of automatic assembly.
