A flexible screw automatic feeding device and method

Abstract

The invention discloses an automatic flexible screw feeding device and method. The device comprises a central processing unit PLC, a vibration feeding frequency modulator, a visual controller, a three-axis module controller and a robot controller; the output end of the visual controller is connected with the central processing unit PLC; the visual controller is used for performing visual analysisand providing visual analysis results to the central processing unit PLC; the central processing unit PLC carries out data interaction with the vibration feeding frequency modulator, the three-axis module controller and the robot controller, and is used for controlling and adjusting the vibration frequency to realize the control of a three-axis module and a robot. The device and method are capableof automatically adjusting the power and adjusting the feeding frequency to improve the stability and usability; the visual inspection is automatic, so that the manual visual inspection and monitoring are avoided, and the assembly abnormality detection also can be judged and eliminated through the visual graphic integrity analysis; and through visual judgment and adjustment, the positioning requirements of the placed workpieces is reduced, and the unnecessary waste caused by repetitive tool manufacturing and technical modification are saved.

Description

technical field [0001] The invention relates to a general module of a flexible production line of an intelligent factory, in particular to the feeding of national standard and non-standard screws within a certain specification range. Background technique [0002] The current screw feeder generally adopts fixed-point conveying, fixed-point grabbing or fixed-point tightening. However, for some special requirements, such as: various types of loading bodies or assemblies, it needs to be adjusted for different three-dimensional coordinates. The conventional screw feeder transports the screws to the exact position through vibration or arrangement, and then the manipulator or the tightening gun then works automatically or manually: manual work requires alignment to increase the requirements of manual work, and loses the meaning of liberating productivity ; Automatic operations are limited by cost and a single product, and it is almost impossible to use products of various specific...
