[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 using a multi-wire cutting machine, the wire breakage alarm is prone to false alarms. Therefore, we have proposed a new type of wire breakage alarm device for multi-wire cutting machines. Utility Model Content

[0008] The proximity switch rod has a roller rotatably mounted on its left end, and the left side of the proximity switch rod is rotatably connected to the alarm housing. The upper and lower left sides of the limiting housing have symmetrical rectangular openings, and the upper and lower ends of the connecting plate have triangular grooves at the rectangular openings, and the rollers are correspondingly inserted into the triangular grooves.

[0009] Preferably, a stabilizing rod is movably inserted into the middle left side of the connecting plate, and the left end of the stabilizing rod is fixedly connected to the left end of the inner cavity of the limiting housing.

[0027] like Figures 1-3 As shown in the figure, this application provides a novel wire breakage alarm device for a multi-wire cutting machine, comprising:

[0028] A connecting base plate 1 is provided, with slide rails 2 symmetrically fixedly connected to the upper and lower sides of the front end of the connecting base plate 1, and a connecting base plate 3 is slidably provided on the slide rails 2. An alarm housing 6 is stacked and fixedly connected to the front end of the connecting base plate 3. A limiting housing 11 is provided inside the alarm housing 6, and a connecting plate 8 is movably inserted into the limiting housing 11. The right end of the connecting plate 8 extends to the outside of the alarm housing 6, and a pulley 9 is rotatably connected to the outer end of the connecting plate 8 through a rotating shaft. A return spring 13 is provided between the inner end of the connecting plate 8 and the left end of the inner cavity of the limiting housing 11.

[0029] Two proximity switches 17 are provided, and the two proximity switches 17 are symmetrically fixedly connected to the upper and lower sides of the inside of the alarm housing 6.

[0030] The proximity switch rod 16 has a roller 21 rotatably mounted on its left end, and the left side of the proximity switch rod 16 is rotatably connected to the alarm housing 6. The upper and lower left sides of the limiting housing 11 have rectangular openings 14 symmetrically opened, and the upper and lower ends of the connecting plate 8 are provided with triangular grooves 15 at the rectangular openings 14. The rollers 21 are correspondingly inserted into the triangular grooves 15.

[0031] like Figure 2As shown: A stabilizing rod 12 is movably inserted into the middle left side of the connecting plate 8, and the left end of the stabilizing rod 12 is fixedly connected to the left end of the inner cavity of the limiting housing 11.

[0032] Specifically: the stabilizer bar 12 can make the left and right displacement of the connecting plate 8 more stable.

[0033] like Figure 3 As shown: A connecting shaft 18 is rotatably inserted into the left side of the proximity switch rod 16, and a stabilizing arc rod 19 is inserted through the right side of the proximity switch rod 16. The opposite ends of the stabilizing arc rod 19 are fixedly connected to the outside of the limiting housing 11. A tension spring 20 is also sleeved on the outside of the stabilizing arc rod 19. The front and rear ends of the connecting shaft 18 are fixedly connected to the inner wall of the alarm housing 6.

[0034] Specifically: the upper end of the tension spring 20 is fixedly connected to the outer end of the stabilizing arc rod 19, and the other end of the tension spring 20 is fixedly connected to the outside of the proximity switch rod 16.

[0035] like Figure 2 and Figure 3 As shown: the center of the stabilizing arc rod 19 coincides with the center of the connecting shaft 18.

[0036] Specifically: the stabilizing arc rod 19 makes the rotation of the proximity switch rod 16 more stable.

[0037] like Figure 2 As shown: the proximity switches 17 are connected in series, and the series proximity switches 17 are connected to the alarm 10. The alarm 10 is fixedly connected to the upper side wall of the alarm housing 6.

[0038] Specifically: the proximity switch 17 uses a proximity switch that is already available on the market, which is existing technology and will not be described in detail here.

[0039] like Figure 1 As shown: A transmission screw 4 is threadedly inserted into the middle of the connecting base plate 3. Both ends of the transmission screw 4 are inserted into the connecting plate through bearings, and the rear end of the connecting plate is fixedly connected to the front end of the connecting base plate 1. A manual disc 5 is fixedly connected to one end of the transmission screw 4.

[0040] Specifically: the transmission screw 4 can rotate in both directions, thereby driving the connecting base plate 3 to move left and right.

[0041] like Figure 1 and Figure 2 As shown: The outer side of the pulley 9 is provided with an arc groove.

[0042] Specifically: the arc groove can make the overlap of the cutting lines stable.

[0043] like Figure 1As shown: The alarm housing 6 has fixing screws 7 inserted at its four corners, and the fixing screws 7 are fixedly inserted at the four corners of the connecting base plate 3.

[0044] Specifically, the alarm housing 6 can be set in a corresponding number according to the number of cutting lines, so as to meet the needs of different multi-wire cutting machines.

[0045] Operating principle: The proximity switch 17 and the alarm 10 are connected in series to an external power supply;

[0046] The connecting base plate 1 is fixedly connected to the external equipment. Then, by manually rotating the manual disk 5, the transmission screw 4 is driven to rotate in both directions, which drives the connecting base plate 3 to move left and right. Then, each pulley 9 is pressed and overlapped on the cutting line. The cutting line will then press the pulley 9, causing the connecting plate 8 to move to the left, thereby pressing the return spring 13. This will force the proximity switch rod 16 to rotate along the connecting shaft 18, causing the right end of the proximity switch rod 16 to move away from the corresponding proximity switch 17.

[0047] If one of the cutting wires breaks, the pulley 9 will not be subjected to compressive force. Under the action of the return spring 13, the connecting plate 8 can be displaced outward. Under the action of the corresponding tension spring 20, the proximity switch rod 16 can rotate around the connecting shaft 18, causing the right end of the proximity switch rod 16 to approach the proximity switch 17, thereby triggering the proximity switch 17 and causing the alarm 10 to sound an alarm, prompting the staff that the cutting wire has broken. In addition, two proximity switches 17 are set to avoid the alarm 10 being triggered falsely.

[0048] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
