Foetal membrane device of robot intelligent rolling and edge covering system

Abstract

The invention discloses a foetal membrane device of a robot intelligent rolling and edge covering system. The foetal membrane device comprises a foetal membrane base; a foetal membrane body is mounted on the foetal membrane base; a mold is arranged at the top of the foetal membrane body; a vacuum plate is mounted at the middle part of the foetal membrane body; rolling guide positioning systems are arranged around the foetal membrane body, and include gripper locking mechanisms and outer plate guide devices; the outer plate guide devices include guide brackets; the guide brackets are fixedly mounted on the upper surface of the foetal membrane base; F-shaped connecting plates are mounted at the top ends of the guide brackets; guide cylinders are mounted at the lower ends of the F-shaped connecting plates; guide plates are mounted at the upper ends of the F-shaped connecting plates; the middle parts of the guide plates are hinged with the F-shaped connecting plates; and guide heads are embedded in the front ends of the guide plates. The foetal membrane device uses the cylinders for driving the swing arm type outer plate guide devices to perform grouping actions, finishes the workpiece positioning before workpieces are contacted with edge rolling foetal membranes, uses the vacuum plate with a larger contact area for replacing a circular vacuum sucker, is better in absorption effect, and improves the rolling operation quality.

Description

[0001] technical field [0002] The invention belongs to the field of machinery manufacturing, and the invention relates to an automobile inner and outer plate hemming system in automobile manufacturing, in particular to a tire membrane device of a robot intelligent rolling hemming system. Background technique [0003] At present, the connection of the inner and outer panels of the automobile body door cover usually uses the hemming process. When using traditional molds and presses for stamping and hemming, since the hemming contour of the outer panel changes according to the shape of the vehicle body, the angle of hemming along the entire contour is also different, and the area where the hemming transition is sharp and the hemming angle is too high In a large area, hemming will be very difficult. At the same time, traditional stamping hemming molds occupy a large area, are costly, and have poor flexibility. In order to shorten the automobile development cycle and improve p...

Problems solved by technology

When using traditional molds and presses for stamping and hemming, since the hemming contour of the outer panel changes according to the shape of the vehicle body, the angle of hemming along the entire contour is also different, and the area where the hemming transition is sharp and the hemming angle is too high For large areas, hemming will be very difficult

At the same time, traditional stamping hemming molds occupy a lot of land, have high cost and poor flexibility. In order to shorten the automobile development cycle and improve product competitiveness, new inner and outer panel connection technology and robot hemming technology are gradually applied in body production

[0004] The robot intelligent rolling hemming system includes a robot, a hemming tool, a fixture system and a hemming film. It uses a robot to carry a special hemming tool to process the inner and outer panels of the workpiece fixed on the fixture system and the hemming film. However, the existing In the rolling hemming process of our company, the positioning of the outer plate is achieved by activating the swing arm to drive the pressure block, and sticking to the side of the film to achieve the positioning effect. The robot hemming tool needs to be opened during rolling, and then closed again after the rolling is completed, resulting in the workpiece being processed and debugged. The cycle is long, the operation is cumbersome, and the position cannot be limited in real time

The clamping of the outer plate adopts the method of starting the swing arm to transfer the force to the outer plate through the inner plate, and at the same time, combined with the vacuum suction cup installed on the edge of the membrane to suck the workpiece, this method will cause a large interference area between the pneumatic swing arm component and the robot. Disadvantages of low clamping force

At the same time, the existing fixture system lacks the guiding and positioning function for transferring the workpiece to the hemming membrane. It basically relies on the gravity of the workpiece itself and external pressure, and completes the guiding and positioning with the help of the lateral force generated by the slope of the hemming membrane surface, and the guiding and positioning effect is not good. , and it is easy to cause scratches to the outer panel
