Smart grinding system for laser seam grinding

Abstract

The invention provides an intelligent grinding system for laser weld grinding. The intelligent grinding system mainly comprises a force control grinding tool, a grinding tool library and a grinding control cabinet, wherein the force control grinding tool is physically connected with a robot; the grinding tool library is arranged in a reach area of the robot; the grinding control cabinet communicates with a robot control cabinet which controls the robot to move; the grinding control cabinet controls the grinding tool and the grinding tool library and feeds back a signal to the robot control cabinet; the robot control cabinet controls the grinding control cabinet and further controls the force control grinding tool and the grinding tool library indirectly. Mechatronic control of the whole equipment can be realized, and technological grinding parameters such as grinding force, linear velocity of each grinding wheel and the like are controllable and adjustable, so that grinding quality is excellent and stable.

Description

technical field [0001] The present invention relates to an intelligent grinding system, in particular to an intelligent grinding system for laser welding seam grinding. Background technique [0002] In the current field of industrial automation, automobile manufacturing, especially the body shop, requires a high level of automation. At present, the production cycle of major automobile companies is 50-60 seconds per vehicle, and the quality requirements are gradually increasing. The welding of the car roof and rear cover has changed from arc welding to laser welding, and the grinding of weld seams has changed from manual grinding to robotic automatic grinding. At present, the laser welding seam grinding of automobile roof mainly adopts old-fashioned mechanical grinding head. Grinding process parameters such as grinding force and grinding wheel linear speed are difficult to control, which makes it difficult to guarantee the grinding quality; because the process parameters are...

Problems solved by technology

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide an intelligent grinding system for laser weld grinding, which can realize the mechatronics control of the entire equipment, and can realize the grinding process parameters such as grinding force and grinding wheel linear speed. The control can be adjusted to ensure excellent and stable grinding quality; real-time detection of grinding wheel consumption, real-time adjustment of the corresponding grinding process parameters, to ensure stable and stable grinding wheel consumption, and the service life of the grinding wheel is increased to 3-4 times the life of traditional mechanical grinding heads; through The use of quick-change abrasive tools can automatically replace the grinding wheel and improve the automation level of the entire grinding equipment; the grinding process parameters are optimized and adjusted in real time according to the consumption of the grinding wheel to ensure that the size of the grinding dust particles is uniform, and the improved new cover is used. It can ensure that the dust removal effect of the entire grinding station reaches more than 90%; through the automatic expansion and contraction of the flexible flange and the use of flexible nylon bonded grinding wheels, the displacement compensation in the direction of the normal force of the grinding can be realized, and it can automatically adapt to the welding seam and the body process. Tolerance changes greatly reduce the difficulty of robot trajectory debugging and improve the intelligence level of the entire equipment; the device of the invention can well make up for the shortcomings of traditional mechanical force control grinding devices, greatly improving the automation and intelligence of automotive laser weld grinding
