Intelligent abrasive paper replacing device for robot grinding and polishing

Abstract

The invention provides an intelligent abrasive paper replacing device for robot grinding and polishing. The intelligent abrasive paper replacing device comprises an abrasive paper removing device and an abrasive paper pasting device; the abrasive paper removing device comprises a cut-in plate, a parallel bearing mechanism and a frame structure, wherein the cut-in plate and the parallel bearing mechanism are connected to the frame structure, and the cut-in plate is provided with a cut-in opening used for being inserted between a polishing machine and abrasive paper; the abrasive paper pasting device comprises an imitated model storing mechanism, a detection mechanism and a sliding block guide rail mechanism, wherein the imitated model storing mechanism comprises an abrasive paper check ring, a lower supporting plate, a supporting rod, a tray and an installing plate, the supporting rod is connected between the abrasive paper check ring and the lower supporting plate to form a moving part to be connected to the sliding block guide rail mechanism, the tray is located between the abrasive paper check ring and the lower supporting plate and connected to the installing plate, and then a static part is formed, and the moving part downwards moves according to a resultant force of self gravity and friction force of a sliding block and a guide rail in the guide rail sliding block mechanism. According to the intelligent abrasive paper replacing device for robot grinding and polishing, automatic replacement of abrasive paper can be achieved, dependence of abrasive paper replacement on people is reduced, and the enterprise labor cost is reduced.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to an intelligent sandpaper replacement device for robot grinding and polishing. Background technique [0002] On the automatic grinding and polishing assembly line of the auto body and auto parts robot, as the grinding and polishing sandpaper of the robot wears out, the sandpaper needs to be replaced frequently. At present, it mainly relies on manual replacement. The replacement of sandpaper is divided into two steps: sandpaper falling off and sandpaper sticking, and the replacement frequency is 3-5 minutes each time. Usually, when replacing sandpaper manually, the robot first needs to move to the safety grating outside the station. After the replacement is completed, it moves to the designated point in the station. The time for artificial sandpaper to fall off is about 4-6 seconds, and the time for artificial sandpaper to stick is about 6-9 seconds, that is, the entire proces...

AI Technical Summary

Problems solved by technology

Failure to replace the sandpaper in time or the quality of the replacement is unstable will directly lead to the shutdown of the robot grinding and polishing line or the frequent occurrence of unstable grinding and polishing quality

The sandpaper replacement of the entire robotic grinding and polishing station is highly dependent on humans, and the level of automation and intelligence is difficult to adapt to the production speed-up and transformation and upgrading of the automotive industry
