Ultrathin material clamping device and clamping method thereof

Abstract

The invention belongs to the technical field of material clamping, and particularly relates to an ultrathin material clamping device and a clamping method thereof. The ultrathin material clamping device comprises a stretching device, a detection device used for detecting the thickness of an ultrathin material, a rack and a control device, wherein one side of the ultrathin material is fixed to the rack; the driving end of the stretching device is connected with the other side of the ultrathin material; the signal output end of the detection device is connected with the input end of the control device; the output end of the control device is connected with the control end of the stretching device, and the control device controls the stretching device to move to tension the ultrathin material; and the stretching device and the detection device are both fixed to the rack. According to the device, the corresponding tensioning force can be matched according to the thickness data of the ultrathin material, and automatic tensioning of the ultrathin material is achieved; and the stretching device controls the movable clamping device to be far away from the fixed clamping device, so that the ultrathin material is stretched flatly, the thickness of the ultrathin material is measured through the detection device to be matched with corresponding tensioning force, the ultrathin material is prevented from being stretched excessively, control is convenient, and the structure is simple.

Description

Technical field [0001] The present invention belongs to the field of material clamping technology, and more particularly to a clamping device of a super thin material and a clamping method thereof. Background technique [0002] As laser cutting technologies continue to evolve, the laser-cut material range is increasingly wide. In existing laser cutting techniques, the material to be cut is needed to be clamped, and then cut under the action of laser cutting equipment. The traditional clamping equipment has a large limit for the species and materials of the material clamping, especially when the texture and size of some materials are different, especially when the texture and size of some materials are not stable. The clamping device will affect the cutting accuracy of the material during the laser machining process to be cut. Thus, in the field of ultra-thin material cutting, there is very little application of laser cutting techniques. The reason is that it is difficult to solve...

AI Technical Summary

Problems solved by technology

Due to the limitation of its own design, the traditional clamping equipment has great limitations on the type of material clamped and the size of the material, especially in the case of some materials with different textures and sizes, it is easy to be unstable when cutting , the clamping effect of the clamping device on the material to be cut will affect the cutting accuracy of the material during laser processing

Therefore, in the field of ultra-thin material cutting, there are few applications of laser cutting technology. The reason is that it is difficult to solve the problem of clamping ultra-thin materials. Ultra-thin materials are too thin and easily deformed. In the field of ultra-thin material cutting, it is urgent to design a clamping device that can quickly clamp ultra-thin materials and stretch the ultra-thin materials flat

[0003] The Chinese patent CN105690156A published on June 22, 2016 is named as a sheet metal tooling fixture. In this patent, the controllable cylinder of the controller pushes the splint to realize the clamping of the sheet in the horizontal direction, and the airflow output device is used to vertically clamp the sheet. Positioning, without hard contact with the thin sheet, the controller judges whether the sheet is pressed according to the signal transmitted by the first pressure sensor, and at the same time detects whether the lower surface of the sheet is flat, and if it is not flat, an alarm signal will be sent through the alarm. Although this patent can Clamping in the horizontal and vertical directions, but the patent can only judge whether the material is stretched flat through the sensor, and cannot control how much tension should be used to tighten the material for different materials. This patent is easy to overstretch the material or The stretching is not enough, the clamping effect is very unstable and the material is easily damaged
