Anti-shake special-shaped flexible material cutting device based on light reflection detection

Abstract

The invention relates to an anti-shaking special-shaped flexible material cutting device based on light reflection detection. The problems that when a cutting device is used for cutting a special-shaped flexible material, a cutter is prone to non-periodic random impact such as deflection around the X axis, the Y axis and the Z axis and displacement in the cutter axis direction, so that the cutting precision is low, and the cutting quality is low are solved. Comprising a rack, a stepping moving mechanism, a cutter rotating mechanism, a cutter rest, a cutter shaft, a blade, a voice coil motor, a four-quadrant photoelectric detector, a laser diode, an upper permanent magnet, a lower permanent magnet, upper stacked piezoelectric ceramics, side stacked piezoelectric ceramics, a fixed outer magnetic ring, a fixed inner magnetic ring, a compression spring, a driving plate and a controller. Laser is emitted to the blade through the laser diode and is detected by the four-quadrant photoelectric detector after being reflected, so that deflection and displacement of the blade in all directions are recognized, control signals in all directions are output after being converted by the controller, and the voice coil motor is controlled to provide axial reverse displacement. The upper stacked piezoelectric ceramics and the side stacked piezoelectric ceramics are controlled to provide reverse deflection amounts.

Description

technical field [0001] The invention relates to an anti-shake special-shaped flexible material cutting device based on light reflection detection. Background technique [0002] Special-shaped flexible material refers to a flexible material with uneven thickness, toughness, hardness, etc. throughout the material, such as animal fur, wallpaper with embossing, etc. Materials with different toughness and hardness have different forms of force on cutting tools in cutting operations. Especially when cutting non-uniform materials, the tool will be subjected to aperiodic random impact, the direction of impact includes the deflection of the tool around the X, Y, Z axes and the displacement along the tool axis, etc., resulting in burrs or other Defects, which will greatly affect the quality of cutting for efficient cutting operations. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an anti-vibration special-shaped flexible material cutting devic...
