Problems solved by technology

[0003] In the actual application process, the service life of the soldering iron tip is limited, and the tip of the soldering iron needs to be replaced frequently. However, when the tip is replaced, the solder joints in the previously programmed program will shift. At this time, we need to correct this deviation. Calibration compensation

Embodiment Construction

[0018] The technical solution of the present invention will be described in detail below.

[0019] For an automatic soldering robot with a camera installed, we use an object with a constant position as a fixed reference point, calibrate the distance from the welding torch to the reference point, and then calibrate the parameters of the rotation axis of the welding torch; when replacing a new soldering iron tip , and then perform system calibration once, then compare the parameters of the two calibrations, and compensate the calculated results into all program files.

[0020] The machine has been calibrated for the first time when it leaves the factory. The specific calibration steps are as follows:

[0021] 1. Take a fixed mark on the PCB board (such as Mark point) as a fixed reference point, and mark the distance from the center of the welding torch to the center of the camera (because the installation position of the camera will not change after leaving the factory ).

Abstract

The invention discloses a method for compensating a soldering point offset program file of an automatic tin soldering robot, which is suitable for operations of catching soldering points by using cameras. The method comprises the following steps of: marking the distance from the center of a soldering nozzle to the center of a camera before leaving a factory; marking a parameter of a rotating shaft of the soldering nozzle; re-marking during the replacement of the soldering nozzle; and respectively subtracting corresponding marked parameters in a current program file from the marked parameters in a current system configuration file through software of the robot, adding the obtained results to coordinates of all the soldering points to obtain new coordinate positions of all the soldering points under the new soldering nozzle, and re-writing into the current program file. According to the method disclosed by the invention, when the soldering nozzle is replaced, the center of the soldering nozzle can still aim at the soldering points due to compensation operation, so that the soldering precision can not be affected. As long as the parameter of the soldering nozzle is marked, a system can automatically update a program, thereby saving time and improving efficiency.

Description

technical field [0001] The invention relates to the technical field of soldering robots, in particular to a method for compensating a welding spot offset program file. When the welding spot offset is caused by changing the welding tip of the welding torch, the system can automatically and accurately compensate the previously prepared program file , no need to redo the program. 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 welding processes to make the ...
