Vision contraposition device for mobile component

Abstract

Disclosed a visual positioning device of moving component belongs to the automatic detecting device in the productive process of electro-mechanic product, which can reduce the design complexity of system and improve the operational efficiency of device. The invention mounts a pick-up head, a electron camera, a semi-transparent mirror and a lighting source on the pick-up device workbench. Wherein, the semi-transparent mirror is mounted between the electron camera and the pick-up head; the electron camera is mounted in a certain inclined angle to make the pick-up head picks up the bottom picture of element to be reflected by semi-transparent mirror to imaged clearly in the electron camera; the projected position of pick-up head on the workbench can be imaged clearly via the semi-transparent mirror. The invention realizes the detection, the displacement adjustment of pick-up element, and the same operation on the mounting position can be synchronously operated with the transfer and mounting detected by one visual system in the transferring process of mounting elements; and the pick-up and the assembling operations on the pick-up device are not need additive process to make the mounting-positioning process more simply and fast.

Description

technical field [0001] The invention belongs to an automatic detection device in the production process of electromechanical products, in particular to a visual alignment device. It is mainly used in the assembly and packaging of mechanical and electrical products in the automatic production process, and realizes the accurate alignment of assembly in automatic production. Background technique [0002] In the automatic assembly process of electromechanical products, a set of automatic or mechanical picking mechanisms are usually used to pick up resistors, capacitors, integrated circuits, chips and other components from the supply place, and transfer them to the installation position to complete the alignment installation. When a component is picked, its positional relationship may be uncertain, so it is necessary to obtain the position information of the picked installed component. When the pick-up mechanism transfers the components to the installation position according to ...

Problems solved by technology

However, this patent application has the following problems: 1. The imaging after two reflections can only be realized at a certain point when the part passes over, so it is necessary to stop or strictly control the synchronization of the movement mechanism and camera exposure; 2. The camera and the suction head are parallel Vertically downward, and there is a certain distance, so for the same installation position, the measurement of the camera and the installation of the pick-up head cannot be carried out at the same time. When the camera is positioned and then the pick-up head is moved to align, the movement error of the motion system will reduce the positioning precision
