TECHNICAL FIELD
[0001] The utility model relates to the field of slicing machine of cutting hard and brittle material especially to a diamond wire cutting mechanism with opposite angle setting of take-up and pay-off mechanism. BACKGROUND
[0002] Photovoltaic silicon wafer is mainly obtained by using diamond wire cutting of slicing machine, and wafer thinning has become a market development trend. It cuts through the take-up and pay-off mechanism winding corresponding number of diamond wires on the guide roller group. The interval distance of the diamond wires between the adjacent turns wound on the guide roller group is the slicing thickness of the slicing product. During cutting, the take-up and pay-off mechanism drives the diamond wire to move back and forth at high speed to complete the cutting work.
[0003] In order to complete the high-speed reciprocating movement of the diamond wire, two groups of take-up and pay-off mechanisms are needed. The two groups of take-up and pay-off mechanisms on the existing diamond wire slicing machine are arranged on the same side of the guide roller group, one group is arranged near the end of the guide roller group, and the other group is arranged away from the other end of the guide roller group. Since one group of take-up and pay-off mechanisms is away from the corresponding end of the guide roller group, it is not conducive to controlling the tension of the diamond wire wound on the guide roller group, so it is difficult to ensure the interval distance between the adjacent diamond wires, thereby affecting the cutting quality of the slicing. SUMMARY
[0004] The utility model aims at solving the above problems existing in the prior art and provides a diamond wire cutting mechanism with opposite angle setting of take-up and pay-off mechanism. Two groups of take-up and pay-off mechanisms are arranged near the two ends of the guide roller group respectively and are arranged in diagonal lines, so that when one group of take-up and pay-off mechanisms pays off the wire, the other group of take-up and pay-off mechanisms is used for taking up the wire. Both groups of take-up and pay-off mechanisms can form suitable tension to wind the diamond wire, thereby being conducive to ensuring the quality of the diamond wire wound on the guide roller group, further being conducive to improving the cutting effect of the diamond wire cutting mechanism and ensuring the quality of the cutting product.
