Method for fixing printed circuit board (PCB) with mark point location function

Abstract

Disclosed is a method for fixing a printed circuit board (PCB) with a mark point location function. The method is characterized by including the following steps: (1) firstly obtaining two mark point images on a reference PCB with a camera when programs are made, (2) obtaining two mark point images which are matched with two chosen mark point positions in the programming process and are on the detected PCB with the camera in the process of welding, and (3) comparing two groups of mark points which are captured in the step (1) and the step (2). If the two groups of the mark points are not out of position, the board position is normal, and if skewing exists, the PCB can be compensated. By the means of the method for fixing the PCB with the mark point location function, welding precision can not be influenced by the factors such as the size, the height and the skewing of the PCB, and simultaneously, welding time is deceased and welding speed is increased.

Description

technical field [0001] The invention relates to the technical field of automatic soldering robots, in particular to a method for adding a PCB board mark point auxiliary positioning function to an automatic soldering robot, so that the same batch of different PCB boards can effectively improve the soldering points of the same batch of PCB boards when performing PCB soldering operations positioning accuracy. Background technique [0002] Automatic soldering robot is an automation system widely used in major factories and enterprises in China. It has the characteristics of stable performance, large working space, fast movement speed and strong load capacity. The welding quality is obviously better than manual welding, which greatly improves the welding operation. production efficiency. Its appearance will greatly reduce production costs and transform manual work into automatic operation of machines. Users can also adjust various parameters of the robot according to different ...

Problems solved by technology

Every time the PCB board is fixed, the on-site operators manually adjust and fix the PCB board to the same position. However, due to the differences in the proficiency, strength, etc. When clamping and fixing, it will cause different deformation or rotation of the PCB, which will lead to deviations in the position of a series of PCB boards corresponding to the same program file, which will lead to poor soldering effect or even inability to solder, and ultimately affect the practicality of the automatic soldering robot sex and work efficiency
