Automatic linear model adjusting method and device

Abstract

The invention discloses an automatic linear model adjusting method. The method includes according to the initial automatic linear model, arranging a robot model, a station model and a clamp model, and arranging the robot model in the first direction of the station model; installing a welding gun model on the robot model, and arranging a workpiece model in the clamp model; marking the workpiece model with a predetermined welding spot position; performing spot welding on the workpiece model by controlling the robot model and welding gun model through the on-site program, and acquiring a simulative welding spot position; acquiring a deviation value between the simulative welding spot position and the predetermined welding spot position according to the simulative welding spot position and the predetermined welding spot position; when the deviation value is larger than a first preset threshold, adjusting the direction of the robot model corresponding to the station model according to the deviation value until the deviation value is smaller than the threshold, and allowing the adjusted robot model to be in the second direction of the station model. The invention further provides an automatic linear model adjusting device.

Description

technical field [0001] The invention relates to the field of automatic lines, in particular to a method and device for digital-analog adjustment of automatic lines. Background technique [0002] As the introduction of new models is getting faster and faster, after the automatic welding production line is established, the automatic line digital model will be collected and saved for simulation or reference of the subsequent introduction of new models. For the automatic line digital model designed by the supplier, the enterprise will independently manage the automatic line digital model, which requires ensuring that the automatic line digital model has complete content and high precision. The existing technology is to directly receive the automatic line digital model from the supplier, arrange the robots at each station according to the layout drawing size designed by the automatic line digital model, and perform spotting simulation on the workpiece after assembling the welding...

AI Technical Summary

Problems solved by technology

However, since the positions of the robot and welding torch are arranged in full reference to the design dimensions, there may be deviations in angle and size from the actual installation position

This deviation may cause no problem in the accessibility of the robot during simulation, but the accessibility of the robot is not enough during actual operation, or the welding torch does not interfere with the workpiece during simulation, but the welding torch interferes with the workpiece during actual operation , resulting in an increase in the cost of equipment transformation and a delay in the schedule, which cannot meet the requirements for use
