Description

technical field [0001] The invention relates to a robot hemming device and a hemming system, belonging to the technical field of sheet metal bending processing. Background technique [0002] The bending of sheet metal parts refers to the processing of changing the angle of the sheet or sheet, such as bending the sheet into V-shape, U-shape and other shapes. At present, the die bending is generally used, the upper die installed on the press presses the lower die, and the folded edge is pressed by the clamping of the die, so as to realize the bending of sheet metal parts. Although this method can realize the realization of sheet metal parts The purpose of bending, but the press is expensive and the input cost is high. [0003] Therefore, the robot is used to carry the hemming device to fold the sheet metal parts, and the sheet metal parts are fixed with a clamp. The purpose of bending the sheet metal parts is achieved by driving the hemming wheel by the robot, which can ensur...

Problems solved by technology

However, different bending shapes and angles of sheet metal parts require a variety of hemming wheels. The existing hemming wheels use fasteners to directly fix the wheel seat on the hemming device, resulting in the installation of the hemming wheel and the It is inconvenient to replace, and the hemming wheel is frequently taken and placed, which is time-consuming and laborious, which affects the processing efficiency of sheet metal parts

In addition, the setting of the folding pressure is mainly related to the thickness of the bending part of the sheet metal and the shape of the bending at the arc corner, that is, the radius of the corner. If the folding pressure is too large, it is easy to form indentations on the surface of the sheet metal parts, which is not beautiful

Generally, for the same type of sheet metal parts, that is, bending with the same thickness, a preload will be set in advance, and the screw position will be adjusted according to the preload. The different folding pressures at different folding positions on the sheet metal part can only meet the requirements of the folding pressure at different positions through the arm of the robot, but the robot still needs to follow the folding contour of the sheet metal part to adjust its posture in real time. Putting the adjustment of the folding pressure on the arm of the robot will affect the attitude of the robot, causing the robot to be unable to walk accurately according to the contour of the folding, which will seriously affect the folding effect of the sheet metal parts
