Description

Technical Field

[0001] The utility model relates to the technical field of monocrystalline silicon rod processing, and particularly relates to a monocrystalline silicon rod cutting device. Background Art

[0002] In high-tech fields such as semiconductors, photovoltaics, and integrated circuits, monocrystalline silicon rods, as a basic material, are widely used in the manufacture of photovoltaic cells, integrated circuits, semiconductor devices, etc. During the production and processing of monocrystalline silicon rods, cutting operations are usually required for subsequent processing operations.

[0003] However, during the current cutting of monocrystalline silicon rods, in order to prevent dust from flying, spray dust suppression operations are usually required. During the current spray dust suppression process, most of the spray water directly flushes the cutting position, resulting in splashing water, which easily causes the water containing dust to splash to the surrounding area, causing environmental pollution and reducing the use effect. Therefore, the applicant proposes a monocrystalline silicon rod cutting device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a monocrystalline silicon rod cutting device to solve the problems raised in the above background art.

[0006] The support mechanism includes a base, and a support frame is fixedly installed on the top of the base;

[0007] The cutting mechanism includes a fixed frame fixedly installed on the top of the base and located outside the support frame. A transmission box is slidably installed inside the fixed frame, and a cutting wire is installed inside the transmission box for transmission;

[0008] The protection mechanism includes two sliding seats symmetrically distributed and slidably installed inside the transmission box. A protective cover is fixedly installed between the two sliding seats. The cutting wire passes through the protective cover. A water spray pipe is fixedly installed inside the protective cover and on the top of the cutting wire. A plurality of nozzles are fixedly installed at equal intervals at the bottom of the water spray pipe.

[0009] Preferably, a collection hopper is fixedly installed at the bottom of the base, and the collection hopper is communicated with the base.

[0010] Preferably, fixing blocks penetrating the fixed frame are fixedly installed on both sides of the transmission box, and hydraulic push rods are fixedly connected between the fixing blocks and the base.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In this single-crystal silicon rod cutting device, by providing a protection mechanism, the cutting wire can be hidden inside the protective cover. When cutting the single-crystal silicon rod, the protective cover can be first clamped on the top of the single-crystal silicon rod, so that the cutting wire can move downward inside the protective cover to cut the single-crystal silicon rod. During the cutting process, the cutting position is sprayed by the water spray head inside the protective cover, so that the water splash can be restricted inside the protective cover, which can effectively reduce the situation that the water splash containing impurities splashes around, and can effectively avoid polluting the surrounding environment, thus improving the use effect when cutting the single-crystal silicon rod.

And in actual applications, the shapes, thicknesses or heights of the components can be enlarged or reduced. The various embodiments listed in the present invention are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Any obvious modification or change made to the present invention does not depart from the spirit and scope of the present invention.

[0024] Please refer to Figures 1-5 As shown in the figure, a single-crystal silicon rod cutting device proposed by the present invention includes a support mechanism 3, a cutting mechanism 1 assembled on the top of the support mechanism 3, and a protection mechanism 2 assembled inside the cutting mechanism 1;

[0025] The support mechanism 3 includes a base 301, and a support frame 302 is fixedly installed on the top of the base 301;

[0026] The cutting mechanism 1 includes a fixed frame 101 fixedly installed on the top of the base 301 and located outside the support frame 302. A transmission box 102 is slidably installed inside the fixed frame 101, and a cutting wire 108 is transmissionally installed inside the transmission box 102;

[0027] The protection mechanism 2 includes two symmetrically distributed slide seats 202 slidably installed inside the transmission box 102. A protective cover 201 is fixedly installed between the two slide seats 202. The cutting wire 108 penetrates through the protective cover 201. A water spray pipe 203 is fixedly installed inside the protective cover 201 and at the top of the cutting wire 108. Nozzles 205 arranged at equal intervals are fixedly installed at the bottom of the water spray pipe 203.

[0028] Based on the above-mentioned structural setting, the single crystal silicon rod cutting device is composed of a cutting mechanism 1, a protective mechanism 2 and a supporting mechanism 3, wherein the single crystal silicon rod can be conveniently supported by the supporting mechanism 3, and the cutting operation of the single crystal silicon rod can be realized by the cutting mechanism 1. During the cutting process, the protective mechanism 2 is engaged with the top of the single crystal silicon rod, and the cutting position can be sprayed in the protective mechanism 2, which can effectively reduce the splashing of water to the surrounding. Specifically, in the working process, by placing the single crystal silicon rod on the supporting frame 302 for support, and by driving the transmission box 102 to move downward, it can be synchronized. By driving the protective mechanism 2 to move downward, the protective cover 201 can be first engaged with the top of the single crystal silicon rod, and the transmission box 102 can continue to move downward to enable the cutting line 108 to contact the single crystal silicon rod. The single crystal silicon rod can be cut by the operation of the cutting line 108. During the cutting process, the position of the cutting port can be located within the protective cover 201. By conveying the spray water to the water spray pipe 203, the position of the cutting port can be sprayed through the nozzle 205, so that the water splash can be limited within the protective cover 201, which can effectively reduce the situation where the water splashes to the surroundings and avoid pollution to the surrounding environment.

[0029] Furthermore, a collecting hopper 303 is fixedly installed at the bottom of the base 301, and the collecting hopper 303 is connected to the base 301. The collecting hopper 303 can collect the sewage after spraying, which is convenient for recycling.

[0030] Furthermore, fixed blocks 104 penetrating the fixed frame 101 are fixedly installed on both sides of the transmission box 102, and a hydraulic push rod 4 is fixedly connected between the fixed block 104 and the base 301. The fixed block 104 can slide up and down along the fixed frame 101, and the transmission box 102 can be driven by the fixed block 104 to move up and down along the inner side of the fixed frame 101 by utilizing the telescopic effect of the hydraulic push rod 4, so as to facilitate the cutting operation of the single crystal silicon rod.

[0031] Furthermore, the transmission box 102 and the cutting line 108 are installed through a plurality of transmission wheels 107, and a motor 103 is fixedly installed at the rear end of the transmission box 102, and the output shaft of the motor 103 penetrates the transmission box 102 and is fixedly connected to one of the transmission wheels 107. The motor 103 can provide power to the transmission wheel 107, and can drive the transmission wheel 107 to rotate, and the cutting line 108 can be tightened through the plurality of transmission wheels 107, and can drive the cutting line 108 to operate, so as to realize the cutting of the single crystal silicon rod.

[0032] Furthermore, the transmission case 102 is slidably mounted on the sliding seat 202 through a sliding column 106. A return spring 105 is sleeved outside the sliding column 106 and between the transmission case 102 and the sliding seat 202. Among them, the sliding seat 202 can slide up and down along the sliding column 106, so that when the protective cover 201 is engaged with the single crystal silicon rod, it does not affect the cutting operation of the transmission case 102 moving downward on the single crystal silicon rod. After the cutting of the single crystal silicon rod is completed, by driving the transmission case 102 to move upward, the return spring 105 can be used to push the sliding seat 202 to move downward, so that the protective cover 201 can be reset, which is convenient for the next cutting, so that the protective cover 201 can first contact and engage with the single crystal silicon rod.

[0033] Furthermore, a docking pipe 204 extending out of the protective cover 201 is fixedly installed at the top of the water spraying pipe 203. The docking pipe 204 is communicated with the water spraying pipe 203. Among them, the docking pipe 204 can facilitate the connection with the water supply equipment, facilitate the introduction of the spraying liquid into the water spraying pipe 203, and perform the spraying operation by using the spray head 205.
