Using this characteristic, semiconductor is widely used in electronic field, such as manufacturing diodes, triodes, integrated circuits and other electronic devices. These semiconductor devices are the core components of modern electronic products, such as computers, mobile phones, smart home devices, etc., and play a key role in promoting information technology development.

[0038] In this embodiment: the pump body 92 can use the suction pipe 93 to pump the liquid in the tank 91. The hose 72 and the annular pipe 71 can transport the liquid pumped by the pump body 92 to multiple inlet pipes 610 and into the cavity 69 of the heat-conducting support plate 64. Subsequently, the liquid discharged from the multiple outlet pipes 611 can enter the annular pipe 81 and be discharged into the tank 91 through the hose 82 to achieve circulation. The temperature sensor can monitor the temperature of the circulating water in the tank 91 in real time and transmit the monitoring information to the microcontroller 95.

The stirring motor 96 can drive the stirring rod to rotate and mix the liquid on the inner wall of the tank 91 to ensure uniform liquid temperature.

[0039] The inner wall of the body 1 is provided with multiple sets of protective components 62. The protective components 62 include a rotary motor 621 fixed in the inner wall of the body 1, and a baffle plate 622 is fixedly connected to the output end of the rotary motor 621.

[0040] In this embodiment: after the heat-conducting cover 65 is reset, as follows: Figure 2 As shown, at this time, the rotary motor 621 can drive the baffle plate 622 to rotate, thereby shielding and protecting the heat-conducting cover plate 65.

[0041] Working principle of this invention: During processing, silicon wafer B is first placed on the heat-conducting tray 64. Then, the clamping cylinder 618 drives the clamping blocks 619 to move. The arc-shaped surfaces on the inner sides of the multiple sets of clamping blocks 619 can clamp and limit the silicon wafer B. At the same time, the multiple sets of heat-conducting trays 64 are located below the formed silicon wafer C. At this time, the lifting frame 612 is opened, and the lifting cylinder 6123 can drive the slide 6122 to move back and forth in the hollow sleeve 6121, thereby driving the frame 613 and the heat-conducting cover plate 65 to move. After moving to a certain height, the flipping motor 614 drives the frame 613 and the heat-conducting cover plate 65 to rotate, so that the heat-conducting cover plate 65 is directly above the silicon wafer B. Then, the lifting frame 612 drives the heat-conducting cover plate 65 to place the silicon wafer. On B, due to the thinness of the silicon wafer, the magnetic column 67 and the magnetic ring 66 attract each other, at which point the assembly 615 is disengaged. When the disengagement cylinder 6151 drives the locking block 6152 to move out of the inner wall of the protrusion 617, the lifting frame 612, in conjunction with the flipping motor 614, drives the frame body 613 to reset. At this time, the heat-conducting plate 64 and the heat-conducting cover plate 65 come into contact with the cut and shaped silicon wafer C. At the same time, the pump body 92 is opened. The pump body 92 can use the suction pipe 93 to pump the liquid in the box 91. The hose 72 and the annular pipe 71 can transport the liquid pumped by the pump body 92 to multiple inlet pipes 610 and into the cavity 69 of the heat-conducting plate 64. Then, the liquid discharged from the multiple outlet pipes 611 can enter the annular pipe 81 and be discharged into the box 91 through the hose 82, thus realizing circulation.

[0042] In the process of laser cutting, the linear motor 3 and the linear motor 4 drive the laser cutter 5 to move, so as to cut the silicon wafer body B. The prior art will not be explained here, such as Figure 9 In the cutting process, the cutting area of the shaped silicon wafer C generates heat. At this time, the heat-conducting base plate 64 and the heat-conducting cover plate 65 can conduct heat out. The heat-conducting cover plate 65 can reduce smoke and splashes splashing onto the shaped silicon wafer C during the cutting process. At the same time, the circulating water moves in the heat-conducting base plate 64, which can cool the heat-conducting base plate 64, thereby improving the cooling effect of the cutting area of the shaped silicon wafer C. The temperature sensor can monitor the temperature of the circulating water in the box 91 in real time and transmit the monitored information to the microcontroller 95. When the circulating water temperature is too high, the microcontroller 95 can control the refrigerator to work to cool the circulating water, ensuring the overall cooling effect. The stirring motor 96 can drive the stirring rod to rotate to mix the liquid on the inner wall of the box 91, ensuring uniform liquid temperature,

[0043] When the cutting is completed and cooled, the lifting frame 612 cooperates with the overturning motor 614 to drive the frame body 613 to move to the upper side of the heat-conducting cover plate 65. The lifting frame 612 drives the frame body 613 to move to the side close to the heat-conducting cover plate 65. The protrusion 617 is inserted in the inner wall of the frame body 613. The clamping block 6152 driven by the air cylinder 6151 is inserted in the inner wall of the protrusion 617. At this time, the lifting frame 612 drives the frame body 613 and the heat-conducting cover plate 65 to move upward and reset, as shown in the state of Figures 2-3 Subsequently, the rotating motor 621 is opened. The rotating motor 621 can drive the shielding plate 622 to rotate, thereby shielding and protecting the heat-conducting cover plate 65.
