Description

Technical Field

[0001] This utility model relates to the field of gallium arsenide processing technology, specifically to a gallium arsenide wire saw cutting device. Background Technology

[0002] Gallium arsenide (GaAs) is an important semiconductor material composed of gallium and arsenic. It has a zincblende crystal structure and is a dark gray solid with a metallic luster when pure. It is chemically stable at room temperature, but arsenic is toxic. As an important compound semiconductor material, GaAs has wide applications in optoelectronic devices, microwave radio frequency devices and other fields. In the processing of GaAs materials, wire sawing is a commonly used process to cut GaAs ingots into wafers of the required thickness.

[0003] In the prior art, Chinese Patent No. CN219855384U discloses a wire saw cutting device with a high wafer yield, including a support frame. A processing table body is located in the middle of the support frame, and a limiting bracket is located at the top of the processing table body. A workpiece body is located between a set of limiting brackets. A combined square frame is slidably connected to one end of the limiting bracket, and transmission sleeves are slidably connected to both sides of the combined square frame. Through the setting of limiting brackets, extrusion blocks, double-ended lead screws, transmission sleeves, support rods, and clamps, when the two sets of transmission sleeves carry the two sets of extrusion blocks to achieve unidirectional stretching, the two sets of extrusion blocks respectively achieve extrusion pre-limitation of the silicon wafer workpiece from the four corner positions. While preventing the silicon wafer workpiece from slipping and causing inconvenience when limited on the support frame, the pre-limited silicon wafer workpiece will accelerate the progress of the downward pressure limiting operation.

[0004] Based on the above information, existing wire saw cutting devices generate a large amount of heat during the gallium arsenide cutting process due to intense friction between the wire saw and the gallium arsenide material, requiring coolant for cooling. During cutting, the coolant, carrying toxic gallium arsenide fragments, splashes everywhere. If operators inhale or come into contact with these fragments, it poses a significant threat to their health. Furthermore, the used coolant and fragments are usually discharged directly without treatment, wasting coolant resources and polluting the environment. Therefore, we propose a gallium arsenide wire saw cutting device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-3, the present utility model provides the following technical solution: A wire saw cutting device for producing gallium arsenide, including a device main body 1. A cutting platform 2 is provided at the bottom of the device main body 1. A protection mechanism for preventing the splashing of coolant and waste chips is provided on the outer wall of the cutting platform 2. The protection mechanism includes a mounting groove 201 opened on the outer surface of the cutting platform 2. A protective cover 3 is slidably mounted on the inner wall of the mounting groove 201.

Two sets of second guide channels 501 are symmetrically arranged on the outer surface of the cutting platform 2, and the second guide channels 501 are perpendicular to the first guide channels 5. The end of the second guide channel 501 is connected to the receiving end. The collecting trough 502 is connected to the second guide trough 501, which has an inclined bottom design. The bottom of the second guide trough 501 is connected to the collecting trough 502, and the horizontal plane of one end of the second guide trough 501 is lower than the horizontal plane of the other end. The collecting trough 502 has a Y-shaped cross-section and is vertically arranged with the second guide trough 501. The collecting trough 502 is located on the side of the cutting platform 2 near the observation window 401.

[0026] like Figures 1-7 As shown, a sealing cover plate 702 is fixedly installed at the end of the collection box 7, and a sealing ring 8 is provided on the outer wall of the sealing cover plate 702. A handle 705 is fixedly installed at the end of the sealing cover plate 702. A magnetic block 704 is fixedly installed on the inner wall of the sealing cover plate 702, and the magnetic block 704 is attracted to the inner wall of the placement groove 602. The filter plate 701 is located on the bottom inner wall of the collection box 7, and the top of the collection box 7 is connected to the feed inlet 601. The bottom of the collection box 7 is connected to the liquid storage tank 603. A symmetrically arranged limiting block 703 is fixedly installed on the side wall of the collection box 7. The bottom of the liquid storage tank 603 is inclined, and the horizontal plane of one side of the bottom of the liquid storage tank 603 connected to the recovery pipe 604 is lower than the horizontal plane of the other side, which is used to recycle the filtered coolant.

[0027] During the cutting process, the generated coolant and waste chips, flushed by the coolant, first fall onto the cutting platform 2. Because the bottom of the first guide channel 5 is inclined and connected to the second guide channel 501, the horizontal plane of one end of the first guide channel 5 is higher than the horizontal plane of the other end. The evenly spaced first guide channels 5 guide the coolant and waste chips to the second guide channel 501. The symmetrically arranged second guide channels 501, perpendicular to the first guide channels 5, also have an inclined bottom and are connected to the collection tank 502. The horizontal plane of one end of the second guide channel 501 is lower than the horizontal plane of the other end, further guiding the coolant and waste chips to the collection tank 502. The collection tank 502 has a Y-shaped cross-section and is perpendicular to the second guide channel 501, located on the side of the cutting platform 2 near the observation window 401. It connects to the top of the collection box 6. The inlet 601 is connected to the collection box 6, which can efficiently introduce coolant and waste into the collection box 6. After entering the collection box 6, the coolant and waste fall into the collection box 7 in the placement tank 602. The filter plate 701 in the collection box 7 intercepts and filters the waste, while the coolant flows into the storage tank 603 through the filter plate 701. The bottom of the storage tank 603 is designed with an inclination, and the horizontal plane on one side connected to the recovery pipe 604 is lower than the horizontal plane on the other side. The filtered coolant flows out smoothly through the recovery pipe 604 under the action of gravity, realizing recycling. The collection box 7 is attracted to the inner wall of the placement tank 602 by the magnetic block 704. The operator can easily pull it out of the placement tank 602 to clean up the waste through the handle 705. After cleaning, it is reinstalled and put back in place to continue the collection of coolant and waste.
