[0003] However, because the surface of the workpiece after laser cutting is not smooth, it changes according to the cutting process. The current vacuum suction cup often has insufficient suction due to adsorption in the gap after cutting, making it difficult to grasp the workpiece, and even fall from the air. fall accident

The invention provides a workpiece fixture that is adaptively adjusted based on workpiece characteristics, comprising a plurality of suction cup beams, two suction cup longitudinal beams, a certain amount of electromagnetic suction cups, a certain amount of vacuum suction cups and a control device; the control device combines the material characteristics of the workpiece and the control device. According to the surface topography characteristics, the positions of the electromagnetic chuck and the vacuum chuck are adaptively adjusted according to the preset adjustment strategy, and the electromagnetic chuck and / or the vacuum chuck are used to grasp the workpiece under the constraints of the minimum required vacuum degree and the shortest moving path. The invention can adjust the positions of the electromagnetic chuck and the vacuum chuck adaptively according to the preset adjustment strategy in combination with the material characteristics and surface topography characteristics of the workpiece, and takes the minimum required vacuum degree and the shortest moving path as constraints, and adopts the electromagnetic chuck and the vacuum chuck. / Or the vacuum sucker grabs the workpiece, so that the workpiece fixture is suitable for workpieces of different shapes as much as possible, reducing the influence of the cutting gap on the grabbing effect, reducing the dependence on vacuum degree and magnetic attraction, and saving energy consumption.
Description
technical field [0001] The invention relates to the field of laser cutting machines, in particular to a workpiece fixture and a material clamping method that are adaptively adjusted based on workpiece characteristics. Background technique [0002] In order to realize automatic cutting, the existing laser cutting machine sometimes uses a cutting assembly with a suction cup assembly to assist the cutting. For example, the suction cup assembly is used to suck the workpiece, and then the suction cup assembly is moved to make the workpiece leave the unloading table and put it into the transport. Material trolley. [0003] However, since the surface of the workpiece after laser cutting is not flat and changes according to the cutting process, the current vacuum suction cups often have insufficient suction force due to being adsorbed on the gap position after cutting, which makes the workpiece difficult to grasp and even falls from the air. Accident occurred. SUMMARY OF THE INVE...
