Description

Technical Field

[0001] This application relates to the field of multi-wire cutting machine technology, and in particular to a novel carbon fiber main roller for a multi-wire cutting machine. Background Technology

[0002] Multi-wire cutting is a novel cutting method that uses the high-speed reciprocating motion of metal wires to bring abrasive particles into the semiconductor processing area for grinding, simultaneously cutting hard and brittle materials such as semiconductors into hundreds of thin wafers in one operation. CNC multi-wire cutting machines have gradually replaced traditional internal circular cutting and become the main method for silicon wafer cutting. High-precision CNC multi-wire high-speed cutting machine tools, developed based on key technologies for high-precision, high-speed, and low-loss cutting control, can comprehensively achieve high-precision, high-speed, and low-loss cutting of semiconductor materials and various hard and brittle materials.

[0003] However, when a multi-wire cutting machine is in use, if the carbon fiber main roller on the main roller is damaged, it is very troublesome or impossible to replace the carbon fiber main roller. Therefore, we have proposed a new type of carbon fiber main roller for multi-wire cutting machines. Utility Model Content

[0004] This application provides a novel carbon fiber main roller for a multi-wire cutting machine to solve the problems mentioned above.

[0005] This application provides a novel carbon fiber main roller for a multi-wire cutting machine, comprising:

[0006] A first connecting shaft, a first threaded segment is fixedly connected to the right end of the first connecting shaft, a prism segment is fixedly connected to the right end of the first threaded segment, a second connecting shaft is fixedly connected to the right end of the prism segment, and a second threaded segment is provided on the outer left side of the second connecting shaft.

[0007] The positioning ring tube has a prism cavity inside, and a prism segment is movably inserted inside the prism cavity. A carbon fiber sleeve is fitted to the outside of the positioning ring tube for limiting.

[0008] A first retaining ring is fixedly provided on the outer side of the right end of the positioning ring tube, and a positioning ring is fixedly provided on the left end of the carbon fiber sleeve shaft. A first nut is threadedly sleeved on the outer side of the first threaded section, and a compression ring is sleeved between the first nut and the positioning ring.

[0009] Preferably, the opposing surfaces of the extrusion ring and the positioning ring are each provided with several interlocking triangular grooves.

[0010] Preferably, a second nut is threaded onto the outer side of the second threaded segment.

[0011] Preferably, the outer side of the positioning ring tube is fixedly connected with multiple limiting protrusions in a ring array.

[0012] Preferably, the inner side of the carbon fiber sleeve shaft is fixedly connected with multiple grooved housings in a ring array, and corresponding limiting protrusions are movably inserted into the interior of the grooved housings.

[0013] Preferably, a second retaining ring is fixedly sleeved on the outer right side of the first connecting shaft.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] The structure provided in this application embodiment allows the extrusion ring to move to the right by manually rotating the first nut with an external tool. This causes the extrusion ring to press the positioning ring to the right, thereby pressing and positioning the carbon fiber sleeve shaft, which in turn makes the positioning of the carbon fiber sleeve shaft more stable.

[0016] When the carbon fiber sleeve shaft is damaged and needs to be replaced, the positioning ring tube and the carbon fiber sleeve shaft can be removed by loosening the second nut with an external tool, making the replacement of the carbon fiber sleeve shaft more convenient.

[0030] A first retaining ring 8 is fixedly provided on the outer side of the right end of the positioning ring tube 11, a positioning ring 6 is fixedly provided on the left end of the carbon fiber sleeve shaft 7, a first nut 3 is threadedly sleeved on the outer side of the first threaded section 12, and a compression ring 4 is sleeved between the first nut 3 and the positioning ring 6.

[0031] Specifically: by manually rotating the first nut 3 using an external tool, the compression ring 4 will be moved to the right, causing the compression ring 4 to press the positioning ring 6 to the right, and thus press the positioning carbon fiber sleeve 7, making the positioning of the carbon fiber sleeve 7 more stable.

[0032] like Figure 1 As shown: The opposing surfaces of the extrusion ring 4 and the positioning ring 6 are each provided with several interlocking triangular grooves 5.

[0033] Specifically: the triangular groove 5 ensures stable positioning of the insertion of the compression ring 4 and the positioning ring 6.
