Description

Technical Field

[0001] The present application relates to the technical field of silicon core processing, and in particular to a semicircular silicon core processing and cutting device. Background Art

[0002] With the rapid development of the semiconductor industry, the demand for silicon materials is also increasing. In the semiconductor manufacturing process, silicon cores (usually cylindrical and square silicon cores) are one of the important raw materials. In order to meet the needs of different application scenarios, these cylindrical silicon cores need to be further processed into specific shapes, such as semicircular silicon cores.

[0003] The silicon core cutting equipment currently on the market mainly uses diamond wire cutting technology. This technology can achieve high-precision cutting of the crystal rod grown from the crystal pulling furnace by adjusting the angle and position of the diamond cutting wire. Such a crystal rod can be cut into dozens or even hundreds of silicon cores. However, although the existing diamond wire cutting technology can achieve high cutting accuracy, it still has some shortcomings in practical applications, especially when facing the processing requirements of non-traditional shapes such as semi-circular silicon cores.

[0004] First, the application of semi-circular silicon cores has not yet been popularized in the market, mainly because of the lack of corresponding processing technology to support mass production of this shape. Secondly, from a design perspective, semi-circular silicon cores have not yet appeared on the market, and from a computational point of view, they have significant design advantages over square silicon cores. For example, the design of semi-circular silicon cores can improve material utilization and reduce cutting losses; its unique geometry helps improve thermal management performance, thereby improving the reliability and efficiency of the final product.

[0005] At the same time, during the cutting process, due to factors such as the way the individual silicon cores are fixed and the tension control of the diamond wire, unstable cutting may occur, resulting in a decrease in the yield rate. Summary of the invention

[0006] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a semicircular silicon core processing and cutting device, which can simultaneously cut multiple cylindrical silicon cores into semicircular silicon cores, improves production efficiency, space utilization and cutting stability through optimized structural design, reduces costs and improves the quality of finished products.

[0011] According to some embodiments of the present application, the solid absorption and adjustment component includes a cylinder and a suction cup, and an electric drive component located at the output end of the cylinder for adjusting the position of the suction cup. An air pump is installed at the output end of the electric drive component, and the output end of the air pump is connected to the air inlet pipe of the suction cup through an air pipe. In order to install the air pump, a fixed disk body is connected to the bottom of the air pump.

[0012] According to some embodiments of the present application, a mounting base is provided at the bottom of the fixed disk body, wherein a central groove is provided through the middle of the mounting base, sliding grooves are provided at the four corners of the end of the mounting base, and a plurality of retractable grooves are provided on the outer side of the mounting base, and a plurality of connecting guide rods are installed in a circular array on the outer surface of the mounting base.

[0013] According to some embodiments of the present application, a rotating motor is installed at the bottom of the inner cavity of the central groove, and a push-connecting central shaft is rotatably provided at the end above the mounting base, wherein the bottom of the push-connecting central shaft is fixedly connected to the output end of the rotating motor.

[0014] According to some embodiments of the present application, the outer surface of the pushing-connecting central axis is connected to a plurality of connecting plate bodies, wherein the other end of the connecting plate body is movably sleeved with a connecting rod member, and the other end of the connecting rod member is movably sleeved with a supporting plate body.

[0017] The beneficial effects of this application are:

When cutting to the top of the silicon core, because the diamond cutting wire cuts the middle of the silicon core, it will not interfere with the diamond cutting wire on the cutting wire wheel group. Similarly, the reverse driving of the toothed disc member can drive the clamping plate body to expand outward, and cancel the limit on the silicon core;

[0019] Under the action of the cylinder, the present solution can drive the suction cup to move downward. At the same time, with the cooperation of the electric drive component, the silicon core pushed by the robot arm can be received, and the silicon core is placed on the clamping plate of the clamping component by using the cylinder and the electric drive component for clamping. When cutting, the suction and solid adjustment component can assist in clamping the silicon core to increase the stability of the clamping. When cutting to the end of the silicon core, the suction cup is tightened by the cooperation of the rotating motor and the pushing and connecting middle shaft, and then the suction and solid adjustment component is pulled up to the top of the machine body as a whole by the cylinder, thereby avoiding the suction and solid adjustment component from hindering the movement of the cutting wire wheel group when cutting the silicon core.

[0020] In this solution, after the cutting wire wheel group cuts the silicon core upward to a certain distance, the hydraulic rod body is used to transport the bottom support platform and the sleeve slide to the inner cavity of the machine body and located at the bottom of the silicon core, and the sleeve slide is unfolded by the scissor lifting group, so that the silicon core passes through the insertion hole and contacts the end of the bottom support platform, so as to support the silicon core at the cutting end, and then under the cooperation of the bottom support platform, the sleeve slide and the clamping assembly, the stability of the silicon core support during cutting is increased. After the silicon core is cut, the bottom support platform and the sleeve slide can be used in conjunction with the hydraulic rod body to transport and pick up the silicon core;

[0021] Finally, the surface area of ​​the semicircular silicon core cut from the cylindrical silicon core in this scheme is increased by 9.54% compared with the triangular silicon core. It is conducive to the deposition of SI in the reduction furnace and accelerates the growth of polysilicon rods. From the cost point of view, it saves 10 yuan per piece compared with the triangular silicon core (the cost of the round silicon core and the triangular silicon core is 60 yuan, and the semicircular silicon core is 30 yuan. In addition to the pickling and cutting costs during processing, a semicircular silicon core is 50 yuan, which saves at least 10 yuan compared with the triangular silicon core of 60 yuan). From the perspective of silicon material consumption, the semicircular silicon core uses 23% more material than the triangular silicon core, and the silicon material generated in production can be fully recycled. At the same time, compared with the cutting of square silicon cores and triangular silicon cores, the semicircular silicon core can be cut from top to bottom in one device, making full use of the equipment space.

[0053] Specifically, the lifting unit 110 is a mechanical device for handling and conveying materials on a production line, such as a hydraulic rod, a cylinder, a motor drive, a linear motor, etc.;

[0054] Furthermore, a through groove 220 is provided on the surface of the mounting platform 200, and the through groove 220 can prevent the mounting platform 200 in the upward state from blocking the cut silicon core, and the through groove 220 can also be used to limit the cut silicon core to prevent the cut silicon core from bifurcation;

[0055] The left and right sides of the machine body 100 are designed with openings, the left side is the feed port, and the right side is the discharge port; and the front side of the machine body 100 is provided with a box door through a hinge; and the left side of the machine body 100 is provided with a mechanical arm 300 through a bracket, and the mechanical arm 300 is a mechatronic device that imitates the function of a human arm, and the mechanical arm 300 can take and transport silicon cores;

[0056] A solid absorption and mixing assembly 400 is disposed at the upper part of the inner cavity of the body 100, and the solid absorption and mixing assembly 400 is used to mix and transport the silicon core; the solid absorption and mixing assembly 400 includes a cylinder 410 and a suction cup 430, and an electric drive component 411 located at the output end of the cylinder 410 for adjusting the position of the suction cup 430, and there are multiple suction cups 430, and an air pump 420 is mounted at the output end of the electric drive component 411, and the output end of the air pump 420 is connected to the air inlet pipe of the suction cup 430 through an air pipe 421. Among them, the surface of the suction cup 430 is installed with an electromagnetic switch valve for controlling the ventilation of a single suction cup 430. In order to install the air pump 420, the bottom of the air pump 420 is connected with a fixed disk body 422, and the bottom of the fixed disk body 422 is connected to the connecting piece on the output shaft of the electric drive component 411. Therefore, the cylinder 410 can vertically displace the solid absorption and mixing component 400, and the electric drive component 411 can horizontally rotate the clamping component 500, so as to change the horizontal angle of the suction cup 430;

[0057] A mounting base 440 is provided at the bottom of the fixed disk body 422, wherein a central groove 441 is provided through the middle of the mounting base 440, and sliding grooves 442 are provided at the four corners of the end of the mounting base 440, and a plurality of storage grooves 443 are provided on the outer side of the mounting base 440, and the storage grooves 443 are used to place the stored suction cups 430, and a plurality of connecting guide rods 444 are installed in a circular array on the outer surface of the mounting base 440, wherein the ends of the connecting guide rods 444 are connected to the bottom of the fixed disk body 422, so that when the cylinder 410 and the electric drive component 411 are working, the mounting base 440 can be driven to move;

[0058] A rotating motor 460 is installed at the bottom of the inner cavity of the central groove 441, and a push-connecting central shaft 450 is rotatably installed at the end above the mounting base 440, wherein the bottom of the push-connecting central shaft 450 is fixedly connected to the output end of the rotating motor 460;

[0059] The outer surface of the push-connection central axis 450 is connected with a plurality of connecting plates 451, wherein the other end of the connecting plate 451 is movably sleeved with a connecting rod 452, and the other end of the connecting rod 452 is movably sleeved with a supporting plate 453. At the same time, a sliding plate 454 is slidably provided in the inner cavity of the sliding groove 442, wherein the end of the sliding plate 454 is connected to the bottom of the supporting plate 453, and the other ends of the sliding plate 454 and the supporting plate 453 are both connected to the surface of the suction cup 430. Therefore, when the push-connection central axis 450 is rotated and subjected to force, it can drive the connecting plate 451 to rotate to a certain angle, and under the limit of the sliding plate 454, pull the connecting rod 452 to drive the supporting plate 453 to move the suction cup 430, thereby driving the suction cup 430 to shrink inward or expand outward;

[0060] Finally, under the action of the cylinder 410, the suction cup 430 can be driven to move downward. At the same time, with the cooperation of the electric drive component 411, the silicon core pushed by the robot arm 300 can be received, and the silicon core can be placed on the clamping plate 550 of the clamping component 500 by using the cylinder 410 and the electric drive component 411 for clamping. When cutting, the solid suction and adjustment component 400 can assist in clamping the silicon core to increase the stability of the clamping. When cutting to the end of the silicon core, the suction cup 430 is tightened by the cooperation of the rotating motor 460 and the pushing and connecting middle shaft 450, and then the solid suction and adjustment component 400 is pulled up to the top of the machine body 100 by the cylinder 410, thereby avoiding the solid suction and adjustment component 400 from hindering the movement of the cutting wire wheel assembly 210 when cutting the silicon core.

[0061] A clamping assembly 500 is installed on the inner side of the solid absorption and mixing assembly 400, and the clamping assembly 500 is used to clamp and fix the silicon core during cutting, and the clamping assembly 500 includes a toothed disc member 510, wherein the inner surface of the toothed disc member 510 is meshingly connected with a plurality of gear members 520, and a driving member 530 for transmitting the gear member 520 is arranged on the upper part thereof, and at the same time, a pushing platform 540 is also arranged below the gear member 520, wherein a clamping plate 550 is movably installed at the bottom of the pushing platform 540, and the end of the pushing platform 540 is connected to the bottom of the gear transmission shaft 521, so that when the gear member 520 is rotated under force, the pushing platform 540 can be driven to rotate, thereby driving the plurality of clamping plates 550 arranged at the bottom thereof to be tightened and adjusted;

[0062] The outer side of the toothed disc 510 is movably mounted with a mounting plate 511 through a bearing, and the outer side of the mounting plate 511 is connected to the inner wall of the body 100, wherein a gear transmission shaft 521 is connected to the center of the gear 1 520, and in order to support the gear transmission shaft 521, an auxiliary support plate 522 is movably mounted on the outer surface of the gear transmission shaft 521 through a bearing, wherein the other end of the auxiliary support plate 522 is connected to the inner wall of the body 100;

[0063] like Figure 7 As shown, the output end of the driving member 530 and the surface of the gear transmission shaft 521 are both sleeved with a gear member 2 531, and there are two gear members 2 531, one gear member 2 531 is sleeved on the output shaft of the driving member 530, and the other gear member 2 531 is installed on the surface of the adjacent gear transmission shaft 521. Therefore, when the driving member 530 is working, the adjacent gear member 1 520 can be driven to rotate through the gear member 2 531, and multiple gear members 1 520 can be driven to rotate simultaneously through the toothed disc member 510, and finally the synchronous adjustment of multiple clamping plates 550 is realized;

[0064] The surface of the push-joint platform 540 is provided with arc-shaped push grooves 541 all around, and the end of the clamping plate 550 is connected to a push-joint rod 551, wherein the axial end of the push-joint rod 551 passes through the arc-shaped push groove 541 and extends to the end of the push-joint platform 540, and the connection between the push-joint rod 551 and the arc-shaped push groove 541 is a sliding connection, and the axial end of the clamping plate 550 passes through a limited support rod 560, wherein one end of the limited support rod 560 is connected to There is a connecting sleeve 561. Since there are multiple clamping plates 550 at the bottom of the pushing platform 540 and multiple limiting support rods 560, the adjacent multiple limiting support rods 560 are connected to the matching connecting sleeves 561, and the outer surface of the connecting sleeve 561 is covered with a supporting plate 562, wherein the outer side of the supporting plate 562 is connected to the inner surface of the body 100, and the supporting plate 562 and the connecting sleeve 561 are used to auxiliary support the limiting support rod 560;

[0065] Finally, when the silicon core is located on the inner side of the adjacent clamping plate 550, the driving member 530 drives the toothed disk member 510 to rotate, and finally synchronously drives the multiple gear members 520 to rotate, and then the arc-shaped pushing groove 541 on the pushing platform 540 and the limiting support rod 560 limit the pushing rod body 551, so that the clamping plate 550 moves and tightens inward to clamp the adjacent silicon core. In this way, multiple silicon cores are clamped and fixed synchronously, and the clamping plate 550 clamps the four corners of the silicon core. When cutting to the top of the silicon core, because the diamond cutting wire cuts the middle of the silicon core, it will not interfere with the diamond cutting wire on the cutting wire wheel assembly 210. Similarly, driving the toothed disk member 510 in the reverse direction can drive the clamping plate 550 to expand outward, thereby canceling the limit on the silicon core.

[0066] An auxiliary transport platform 600 is set up on the right side of the body 100, and a bottom support platform 610 is set at the end of the auxiliary transport platform 600, wherein a sleeve slide 611 is stacked on the upper end of the bottom support platform 610, and a socket 612 adapted to the silicon core is opened on the surface of the sleeve slide 611, wherein the inner cavity of the socket 612 is provided with an air bag, and after determining the specifications of the cylindrical silicon core, the air bag can be inflated to change the aperture of the socket 612, and multiple sockets 612 are unfolded, and a scissor lift group 613 is installed on the side of the socket 612, and the scissor lift group 613 is also called a scissor lift or a scissor lift platform, which is a common industrial and commercial lifting equipment. Its name comes from its unique mechanical structure-when the lifting frame is raised, its support structure will unfold like scissors to form a cross "X" shape, hence the name, and it is mainly composed of a base, multiple groups of cross support arms, a scissor mechanism, a platform and a drive system. When the lift is raised, the support arms open like scissors and when it is lowered, they close;

[0067] Hydraulic rod bodies 620 are installed at both ends of the bottom of the auxiliary transport platform 600, and plug-in slide grooves 601 are penetrated at both ends of the inner surface of the auxiliary transport platform 600, and the output end of the hydraulic rod body 620 is connected to a support seat 630, wherein the other end of the support seat 630 penetrates the inner cavity of the plug-in slide groove 601 and is connected to the bottom of the bottom support platform 610, and an L-shaped receiving seat 631 is connected to the left side of the bottom of the bottom support platform 610, and the bottom of the L-shaped receiving seat 631 is in sliding contact with the end of the auxiliary transport platform 600, so that the bottom support platform 610 can be auxiliary supported by the support seat 630 and the L-shaped receiving seat 631;

[0068] Furthermore, another set of mechanical arms 300 can be set up on the right side of the hydraulic rod body 620, so that the cut silicon cores sent out by the bottom support platform 610 and the sleeve slide 611 can be taken and sent to the next processing link;

[0069] Finally, after the cutting wire wheel assembly 210 cuts the silicon core upward to a certain distance, the hydraulic rod body 620 is used to transport the bottom support platform 610 and the sleeve slide 611 to the inner cavity of the body 100 and to the bottom of the silicon core, and the sleeve slide 611 is unfolded by the scissor lifting assembly 613, so that the silicon core passes through the socket 612 and contacts the end of the bottom support platform 610, so as to support the silicon core at the cutting end, and then under the cooperation of the bottom support platform 610 and the sleeve slide 611 and the clamping assembly 500, the stability of the silicon core support during cutting is increased. After the cutting of the silicon core is completed, the bottom support platform 610 and the sleeve slide 611 can be used in conjunction with the hydraulic rod body 620 to transport and pick up the silicon core.

[0072] Comparison of the circumference of the semicircular silicon core, the triangular silicon core and the square silicon core (72 mm);

[0073]

[0074] It can be seen that the surface area of ​​the semicircular silicon core cut from the cylindrical silicon core in this scheme is increased by 9.54% compared with the triangular silicon core. It is conducive to the deposition of SI in the reduction furnace and accelerates the growth of polysilicon rods. From the cost point of view, it saves 10 yuan per piece compared with the triangular silicon core (the cost of the round silicon core and the triangular silicon core is 60 yuan, and the semicircular silicon core is 30 yuan. In addition to the pickling and cutting costs during processing, a semicircular silicon core is 50 yuan, which saves at least 10 yuan compared with the triangular silicon core of 60 yuan). From the perspective of silicon material consumption, the semicircular silicon core uses 23% more material than the triangular silicon core, and the silicon material generated in production can be fully recycled. At the same time, compared with the cutting of square silicon cores and triangular silicon cores, the semicircular silicon core can be cut from top to bottom in one device, making full use of the equipment space.

[0075] Specifically, the working principle of the semicircular silicon core processing and cutting device is as follows: when the silicon core is located on the inner side of the adjacent clamping plate 550, the driving member 530 drives the toothed disc member 510 to rotate, and finally synchronously drives the multiple gear members 520 to rotate, and then the arc-shaped push groove 541 on the pushing platform 540 and the limiting support rod 560 limit the pushing rod body 551, so that the clamping plate body 550 moves and tightens inward to clamp the adjacent silicon core, thereby clamping and fixing the multiple silicon cores synchronously, and the clamping plate body 550 clamps the four corners of the silicon core. When cutting to the top of the silicon core, the diamond cutting wire cuts the middle of the silicon core, so that it will not interfere with the diamond cutting wire on the cutting wire wheel group 210. Similarly, the reverse driving of the toothed disc member 510 can drive the clamping plate body 550 to expand outward, and cancel the limit on the silicon core;

[0076] Under the action of the cylinder 410, this solution can drive the suction cup 430 to move downward. At the same time, under the cooperation of the electric drive component 411, it can receive the silicon core pushed by the robot arm 300, and use the cylinder 410 and the electric drive component 411 to place the silicon core on the clamping plate 550 of the clamping component 500 for clamping. When cutting, the suction and solid adjustment component 400 can assist in clamping the silicon core to increase the stability of the clamping. When cutting to the end of the silicon core, the suction cup 430 is tightened by the cooperation of the rotating motor 460 and the pushing and connecting middle shaft 450, and then the suction and solid adjustment component 400 is pulled up to the top of the machine body 100 by the cylinder 410, thereby avoiding the suction and solid adjustment component 400 from hindering the movement of the cutting wire wheel assembly 210 when cutting the silicon core.

[0077] In this solution, after the cutting wire wheel assembly 210 cuts the silicon core upward to a certain distance, the hydraulic rod body 620 is used to transport the bottom support platform 610 and the sleeve slide 611 to the inner cavity of the body 100 and located at the bottom of the silicon core, and the sleeve slide 611 is unfolded by the scissor lifting group 613, so that the silicon core passes through the insertion hole 612 and contacts the end of the bottom support platform 610, so as to support the silicon core at the cutting end, and then under the cooperation of the bottom support platform 610 and the sleeve slide 611 and the clamping assembly 500, the stability of the silicon core support during cutting is increased. After the cutting of the silicon core is completed, the bottom support platform 610 and the sleeve slide 611 can be used in conjunction with the hydraulic rod body 620 to transport and pick up the silicon core.
