Description

Technical Field

[0001] This application relates to the field of single-wire cutting machine technology, and in particular to a novel grooved wheel structure for a single-wire cutting machine. Background Technology

[0002] Single-wire cutting is a novel cutting method that uses the high-speed reciprocating motion of a metal wire to bring abrasive into the semiconductor processing area for grinding, simultaneously cutting hard and brittle materials such as semiconductors into thin wafers. CNC single-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 single-wire cutting machine is in use, if the rubber overlapping ring in the grooved wheel is damaged, the entire grooved wheel structure needs to be replaced or the machine needs to be returned to the factory for repair, which is very troublesome and wasteful of resources. Therefore, we have proposed a new grooved wheel structure for a single-wire cutting machine. Utility Model Content

[0004] This application provides a novel grooved wheel structure for a single-wire cutting machine to solve the problems mentioned above.

[0005] This application provides a novel grooved wheel structure for a single-wire cutting machine, comprising:

A positioning ring is fixed at the front center of the sleeve ring. A compression positioning ring disc is sleeved on the outside of the positioning ring. The ring wheel is located between the main wheel and the compression positioning ring disc. The positioning ring, sleeve ring and main wheel are an integral structure, and a connecting hole is opened through the middle of the positioning ring, sleeve ring and main wheel.

[0007] Preferably, the outer side of the ring wheel has a groove, and six arc-shaped shells are fixedly embedded in a ring array on the inner side of the ring wheel.

[0008] Preferably, the outer side of the sleeve ring has six arc grooves arranged in a ring array.

[0009] Preferably, the front side of the main wheel has threaded holes at the rear end of the corresponding arc groove.

[0010] Preferably, a bolt is threaded into the inside of the threaded hole, and the bolt passes through and inserts into the compression positioning ring.

[0011] Preferably, the arc-shaped housing after the ring wheel is installed combines with the corresponding arc-shaped groove to form a circular hole.

[0012] Preferably, the bolt is also inserted through the corresponding circular hole.

[0013] The technical solutions provided in this application have the following advantages compared with the prior art:

[0014] The structure provided in this application embodiment allows the rear end face of the compression positioning ring disc to compress the ring wheel during the bolt tightening process, thereby making the positioning of the ring wheel more stable and secure. Furthermore, when the ring wheel is damaged, the compression positioning ring disc and the ring wheel can be disassembled by removing the bolt, making the replacement of the ring wheel more convenient and eliminating the need for factory repair.

[0015] At the same time, by setting the arc-shaped shell, the positioning of the ring wheel can be made more stable. Attached Figure Description
