Photoelectric alignment mechanism and method for utilizing photoelectric alignment mechanism for alignment

Abstract

The invention belongs to the field of automatic production, and provides a photoelectric alignment mechanism and a method for utilizing the photoelectric alignment mechanism for alignment. The mechanism comprises a control system, a robot and a suction cup tool. The suction cup tool is in a rectangular shape. The center points of two opposite edges of the suction cup tool are a first base point and a second base point correspondingly. Each of the first base point and the second base point is provided with a photoelectric switch used for detecting the position of a to-be-aligned workpiece, andthe suction cup tool is arranged on a swing arm of the robot and can rotate around the first base point and the second base point at different times. The mechanism utilizes the control system for controlling the connecting line of the first base point and the second base point on the alignment mechanism to be parallel to one edge of the to-be-aligned workpiece, then, the photoelectric switches areused for being matched with the program algorithm of the control system, the middle point of one edge of the to-be-aligned workpiece is found, and then, the middle point which passes through the middle point and is perpendicular to the edge is found and is the center of the rectangular workpiece. The integral structure is simple, cost is low, influences from the surrounding environment are avoided, and the accuracy rate is high.

Description

technical field [0001] The invention belongs to the field of automatic production, and in particular relates to a photoelectric alignment mechanism and an alignment method using the same. Background technique [0002] In the automatic production line, in the process of producing products, transferring the position of products is an essential working condition. When the product is being transferred, sometimes it is necessary to grab the center of the product to ensure the balance and stability of the product during the transfer. [0003] At present, there are many kinds of incoming products on the production line and they are placed irregularly. In the existing technology, visual recognition technology is mostly used. Although this problem is solved to a certain extent, there are some other problems at the same time. First of all, the visual recognition system is expensive, resulting in high production costs; secondly, the recognition success rate of visual recognition techn...
