Embodiment Construction

[0019] combine figure 1 , The equipment for automatic transformer assembly of the present invention includes a bracket, a manipulator 1, a camera 2, a material tray 3, and a conveyor 4. The manipulator 1 is set on the support and can rotate in three degrees of freedom, and the camera 2 is set on the manipulator 1 . The material tray 3 is arranged on the conveyor 4 , and the material tray 3 moves together with the conveyor belt of the conveyor 4 . The conveyor 4 is equipped with a photoelectric switch at the working area of ​​the manipulator 1. When the material tray 3 triggers the photoelectric switch, the conveyor belt stops. When the workpiece assembly of a process is completed, the material tray 3 is transferred to the next station.

[0020] combine figure 2 , a machine vision-based automatic assembly method for transformers, including building a standard part feature database and assembly of transformers to be assembled.

[0021] The data stored in the standard part fe...

Abstract

The invention provides an automatic transformer assembly method based on machine vision. The method comprises the steps of a standard part feature database of a to-be-assembled transformer is established; images of a part placement area and an assembly area are collected; image features are extracted; parts are matched; a manipulator assembly path is acquired; and assembling is conducted. A camerais adopted for replacing human eyes for measuring the assembly position, the assembly precision of products is improved, meanwhile, the labor consumption is reduced, the assembly method is stable inoperation, the production efficiency and the production automation level are greatly improved, and the method is suitable for the large-batch transformer production assembly process.

Description

technical field [0001] The invention relates to a mechanical automation and machine vision technology, in particular to a machine vision-based automatic transformer assembly method. Background technique [0002] With the rapid development of machine vision technology, flexible assembly has gradually attracted people's attention. The use of vision technology can enable the robot to make independent decisions based on factors such as the surrounding environment and operating conditions, realize dynamic adjustment of the position of the grab point, and quickly adjust the attitude of the parts. Precisely place it in the area to be assembled, etc., so as to improve the stability and production efficiency of product assembly. Nowadays, under the trend of increasing demand for manufacturing products and higher and higher product quality requirements, flexible assembly is widely used in production practice because of its high assembly accuracy, strong stability, and high work effici...
