Problems solved by technology

[0004] The winding mechanism of the diamond wire cutting machine in the prior art has the following defects: the pay-off roller and the take-up roller are vertically arranged, and the winding mode of twelve guide wheels is adopted, the number of guide wheels is large, and the diamond wire winding The overall structure of the diamond wire cutting machine is not compact because the distance is long and the layout of the wire wheels is cumbersome; and every time the diamond wire passes through a guide wheel, it needs to be bent and changed once, resulting in loss of stiffness of the diamond wire, and too many guide wheels make the stiffness of the diamond wire Decrease, affecting the stability of the tension, prone to wire breakage and jumper problems

Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0057] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 Shown, the winding mechanism of diamond wire cutting machine of the present invention, it comprises and comprises pay-off roller 1, driving shaft 2, driven shaft (in front view, driven shaft is positioned at driving shaft rear, is blocked by it, but because driven shaft It is a mature prior art content, so it will not be described in detail), take-up roller 3 and diamond wire 4. The above-mentioned pay-off roller 1, driving shaft 2, driven shaft and take-up roller 3 are all installed on the frame 5 of the diamond wire cutting machine; and the pay-off roller 1, driving shaft 2, driven shaft and take-up roller 3 All driven by their own different motors. The pay-off roller 1 and the take-up roller 3 are both transverse.

[0058]The frame 5 is pr...

Abstract

The invention discloses a wire winding mechanism of a diamond wire cutting machine and a constant tension control method based on the wire winding mechanism. The wire winding mechanism comprises a wire unwinding roller, a driving shaft, a driven shaft, a wire winding roller, an upper moving module, a lower moving module, an upper swing arm, a lower swing arm, a first fixed guide wheel and a secondfixed guide wheel. A moving guide wheel is installed on each moving module, and a swing guide wheel is installed on each swing arm. A diamond wire is led out of the wire unwinding roller, passes through the first moving guide wheel, the first swing guide wheel and the first fixed guide wheel, then is wound around the driving shaft and the driven shaft to form a wire net, passes through the secondfixed guide wheel, the second swing guide wheel and the second moving guide wheel, and finally is led to the wire winding roller. The control method is characterized in that the feed-forward standardangular velocity wt calculated through feed-forward control and the angular velocity soft amplitude limiting treatment fine adjustment quantity dwl are superposed, so that the target angular velocitywy of each wire roller is acquired. The wire winding mechanism and the control method have the advantages that the number of the guide wheels can be reduced, the rigidity of the diamond wire can be improved, and the wire routing tension can be constant.

Description

technical field [0001] The invention relates to the field of cutting machinery and equipment, in particular to a winding mechanism of a diamond wire cutting machine and a constant tension control method based on the mechanism. Background technique [0002] In recent years, with the rapid development of the solar energy industry, the demand for hard and brittle materials such as monocrystalline silicon, polycrystalline silicon and piezoelectric ceramics has risen rapidly. As the main cutting equipment for hard and brittle materials such as solar silicon wafers, the diamond wire cutting machine has been more and more widely used due to its advantages of high cutting efficiency and good processing stability. [0003] The diamond wire cutting machine uses a winding mechanism to route wires to cut silicon materials. The winding mechanism of the diamond wire cutting machine in the prior art includes a vertical pay-off roller, a driving shaft, a driven shaft, a vertical take-up ro...
