Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire cutting equipment, and particularly provides a wire cutting machine. BACKGROUND

[0002] The wire cutting machine is a device for cutting materials (such as silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials and the like) through the high-speed reciprocating movement of a cutting wire. The slicing process is realized by a slicing machine. The cutting area of the slicing machine needs to be sprayed with cutting fluid. The powder (such as silicon powder) generated after the cutting work is also suspended in the cutting area and mixed into the cutting fluid. The sprayed cutting fluid will flow along the cutting wire onto the wire running mechanism. After the cutting wire leaves the cutting mechanism, it first passes through a turning assembly. Therefore, the cutting fluid and the silicon powder mixed into the cutting fluid will affect the normal work of the turning wheel and even cause damage to the turning wheel. The slicing machine is only one type of wire cutting machine. Other wire cutting machines such as square cutting machines also have the above-mentioned problems.

[0003] Therefore, there is a need in the art for a new wire cutting machine to solve the problem that the existing wire cutting machine cannot well protect the turning assembly or the turning assembly cannot work stably. SUMMARY

[0004] The present application aims to solve the above technical problems, i.e., to solve the problem that the existing wire cutting machine cannot well protect the turning assembly or the turning assembly cannot work stably.

[0005] In a first aspect, the present application provides a wire cutting machine, which comprises a cutting chamber, a protection chamber, a cutting mechanism and a wire running mechanism. The wire running mechanism comprises a turning assembly which is configured to make the cutting wire turn and then wind around the cutting mechanism so that the cutting mechanism can perform cutting work through the cutting wire. The protection chamber is arranged in the cutting chamber, the cutting mechanism is arranged in the cutting chamber, and the turning assembly is arranged in the protection chamber.

[0006] The turning assembly is arranged in the protection chamber. Compared with the prior art in which the turning assembly is directly arranged in the cutting chamber, the turning assembly arranged in the protection chamber is greatly reduced in the influence of the cutting fluid. Therefore, the stability of the turning assembly in work is increased. At the same time, the cutting chamber can also reduce the entry of silicon powder, thereby reducing the damage of the silicon powder to the cutting wire in the turning assembly. Therefore, the service life of the turning assembly and the cutting wire is prolonged.

The protection chamber is arranged on the inside of the isolation door. A shielding edge is arranged on the inside of the isolation door. The shielding edge forms a top cover of the protection chamber. Furthermore, the turning assembly comprises a turning wheel.

[0008] By setting the shielding edge, most of the liquid can be shielded, thereby effectively preventing the liquid from entering the protection chamber.

[0009] In the preferred technical scheme of the wire cutting machine, the turning assembly further comprises a fixed support and a wire passing support, the fixed support is slidably arranged on the wire cutting machine, the turning wheel is rotatably arranged on the fixed support, and the wire passing support is fixedly arranged on the fixed support and has a wire passing groove for guiding the cutting wire to extend from the inner side of the protection chamber to the outer side of the protection chamber.

[0010] By fixing the turning wheel and the wire passing support on the fixed support which is slidably connected, the position of the fixed support can be adjusted according to the required position of the cutting wire, so that the cutting wire enters the cutting chamber in the optimal position.

[0011] In the preferred technical scheme of the wire cutting machine, part of the wire passing support is arranged between the shielding edge and the waterproof assembly of the turning wheel, and the wire passing support extends from the inner side of the protection chamber to the outer side of the protection chamber.

[0013] In the preferred technical scheme of the wire cutting machine, the turning assembly further comprises a height adjusting block, the height adjusting block is slidably arranged on the fixed support and has a sliding direction perpendicular to the sliding direction of the fixed support, the turning wheel is rotatably arranged on the height adjusting block, and the wire passing support is fixedly arranged on the height adjusting block.

[0014] In the preferred technical scheme of the wire cutting machine, the wire passing support comprises a fixed part and a bearing part which are connected to each other, the bearing part further comprises a stop part on the side away from the fixed part, and the wire passing groove passes through the fixed part, the bearing part and the stop part.

[0015] The wire passing groove arranged on the wire passing support can ensure that the cutting wire enters the cutting chamber after passing through the wire passing groove, thereby increasing the stability of the cutting wire during operation.

[0016] In the preferred technical scheme of the wire cutting machine, the wire cutting machine further comprises a main frame, the wire passing mechanism is located on the inner side of the main frame, and the wire passing mechanism further comprises a wire winding and unwinding assembly, a guide assembly and a tension assembly.

[0017] In the preferred technical scheme of the wire cutting machine, the turning wheel is arranged on the side close to the isolation door in the protection chamber.

[0018] In the preferred technical scheme of the wire cutting machine, the protection chamber further comprises a side baffle, a deflector water-proof assembly and a water baffle, the deflector water-proof assembly is arranged below the shielding edge, the side baffle is arranged on the side opposite to the deflector water-proof assembly and below the isolation door, and the water baffle is arranged below the side baffle and inward, and the isolation door, the shielding edge, the deflector water-proof assembly, the water baffle and the side baffle jointly enclose the protection chamber.

[0019] In the preferred technical scheme of the wire cutting machine, the wire cutting machine further comprises a drainage and exhaust unit, the drainage and exhaust unit comprises a main exhaust pipeline, a main drainage pipeline, an auxiliary exhaust pipeline and an auxiliary drainage pipeline, a first end of the main exhaust pipeline is in communication with the cutting chamber, and a second end thereof is in communication with the outside; a first end of the main drainage pipeline is in communication with the cutting chamber, and a second end thereof is in communication with the outside; a first end of the auxiliary exhaust pipeline is in communication with the protection chamber, and a second end thereof is in communication with the main exhaust pipeline; and a first end of the auxiliary drainage pipeline is in communication with the protection chamber, and a second end thereof is in communication with the main drainage pipeline.

[0020] The communication of the protection chamber with the auxiliary exhaust pipeline and the auxiliary drainage pipeline can ensure that the liquid and the silicon powder in the protection chamber are effectively drained, reduce the influence of the liquid and the silicon powder on the deflector assembly in the protection chamber, and thus increase the stability of the deflector assembly in operation.

[0021] In the preferred technical scheme of the wire cutting machine, the first end of the auxiliary exhaust pipeline is in communication with the first end of the auxiliary drainage pipeline and then in communication with the protection chamber, so that the first end of the auxiliary exhaust pipeline and the first end of the auxiliary drainage pipeline share one gas-liquid inlet.

[0022] The sharing of one outlet, i.e., the gas-liquid inlet, of the exhaust pipeline and the auxiliary drainage pipeline by the exhaust pipeline and the auxiliary drainage pipeline can reduce the number of outlets of the exhaust and drainage, and thus is more conducive to the setting of the protection chamber into a negative pressure.

[0023] In the preferred technical scheme of the wire cutting machine, the auxiliary drainage pipeline is arranged below the auxiliary exhaust pipeline.

[0024] The downward flow of the liquid, the arrangement of the auxiliary drainage pipeline below the auxiliary exhaust pipeline is more conducive to the drainage of the liquid, and at the same time reduces the content of the silicon powder entering the auxiliary drainage pipeline and the content of the liquid entering the auxiliary drainage pipeline.

[0028] Since the silicon powder floats upward, the main exhaust pipeline is arranged at a position higher than that of the auxiliary exhaust pipeline, which is more conducive to the collection of silicon powder from the auxiliary exhaust pipeline into the main exhaust pipeline; since the liquid flows downward, the main liquid discharge pipeline is arranged at a position lower than that of the auxiliary liquid discharge pipeline, which is more conducive to the collection of liquid in the auxiliary liquid discharge pipeline into the main liquid discharge pipeline.

[0029] In the preferred technical scheme of the above-mentioned wire cutting machine, the bottom of the protection chamber is a water baffle, the gas-liquid inlet is arranged on the water baffle, and the gas-liquid inlet is arranged at the lowest part of the protection chamber.

[0030] Since the liquid flows downward, the gas-liquid inlet should be arranged at the lowest part of the protection chamber.

[0031] Through the above arrangement, the steering assembly of the present application is protected by the protection chamber and is affected as little as possible by the cutting fluid and silicon powder in the cutting chamber, thereby ensuring the stability of the steering assembly. The arrangement of the protection chamber also reduces the damage of the silicon powder to the cutting wire on the steering assembly. Since the steering assembly further comprises a fixed support, a threading support and a steering wheel, the steering wheel can move on the sliding rail under the driving of the fixed support, thereby ensuring that the cutting wire on the steering wheel can enter or exit the cutting chamber at the best position. Meanwhile, the cutting wire can also enter the cutting chamber through the threading groove. The arrangement of the threading groove ensures that the cutting wire enters the cutting chamber more stably. In addition, in order to better adjust the position of the cutting wire, the steering assembly further comprises an angle adjusting block capable of adjusting the angle of the steering wheel and a height adjusting block capable of adjusting the height of the steering wheel. In addition, the protection chamber is in communication with the auxiliary liquid discharge pipeline and the auxiliary exhaust pipeline. The auxiliary liquid discharge pipeline can discharge the cutting fluid entering the protection chamber, and the auxiliary exhaust pipeline can discharge the silicon powder in the protection chamber. The above arrangement can make the steering assembly work more stably. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0046] The preferred embodiments of the present application will be described below with reference to the accompanying drawings and in conjunction with a slicing machine. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application. Those skilled in the art can make adjustments as needed to adapt to specific application occasions. For example, although the slicing machine is taken as an example in the description, the present application can also be applied to other types of wire cutting machines, such as square root machines, etc., which are all within the protection scope of the present application.

[0047] It should be noted that in the description of the present application, the terms indicating the direction or positional relationship of "upper", "lower", "inner", "outer" and the like are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and is not intended to indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0048] In addition, it needs to be explained that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting" should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] As shown in Figure 1 、 Figure 2 The slicer includes a main frame A, a cutting chamber 1, a take-up chamber 2, a protection chamber 3, a cutting mechanism 11 and a wire running mechanism 20 are arranged in the main frame A, the protection chamber 3 is arranged in the cutting chamber 1, the cutting mechanism 11 is also arranged in the cutting chamber 1, the wire running mechanism 20 includes a take-up assembly (hereinafter the take-up assembly will be introduced as a pay-off roll 21), a guide assembly 24, a tension assembly 22 and a turning assembly 23 arranged in the protection chamber 3, the pay-off roll 21 and the tension assembly 22 are arranged in the take-up chamber 2, the cutting wire 25 released by the pay-off roll 21 is guided into the tension assembly 22 through the guide assembly 24, then enters the protection chamber 3 through the tension assembly 22 and is guided into the turning assembly 23, then passes out of the protection chamber 3 and enters the cutting chamber 1 to be connected with the cutting mechanism 11, so that the cutting mechanism 11 can perform cutting work through the cutting wire 25.

[0050] The slicer is mainly used for cutting and processing hard and brittle materials such as crystalline silicon, and this process is mainly realized through repeated cutting of the cutting wire 25. The slicer of the present application includes a main frame A, and the main frame A is provided with chambers, including a cutting chamber 1, a take-up chamber 2 and a protection chamber 3. The take-up chamber 2 is provided with a wire running mechanism 20, including a pay-off roll 21, which is used to take up and release the cutting wire 25. The movement process of the cutting wire 25 on the slicer is as shown in Figure 2As shown, when cutting the crystalline silicon, the wire releasing roller 21 first releases the cutting wire 25, and then the cutting wire 25 is guided to the tension assembly 22 by the guide assembly 24, the tension assembly 22 tensionally tightens the cutting wire 25, so as to give the cutting wire 25 a stable tension value, and then ensure that the wire net described below is always in the best tension state. After the cutting wire 25 is tensionally tightened by the tension assembly 22, it moves to the turning assembly 23 in the protection chamber 3, the turning assembly 23 adjusts the cutting wire 25 according to the required direction and angle of the cutting wire 25 to guide the cutting wire 25 into the cutting chamber 1, so as to wind the cutting wire 25 on the cutting mechanism 11 in a suitable position to form a wire net. After the wire net is formed, the cutting wire 25 passes out from the other end of the cutting chamber 1, passes through the turning assembly 23 at the other end (herein referred to as the wire outlet end) of the cutting chamber 1, and then passes through the tension assembly 22 and the guide assembly 24 to return to the wire releasing roller 21 (herein the wire releasing roller 21 functions as a wire collecting roller). In addition, the turning assembly 23, the tension assembly 22 and the guide assembly 24 at the other end (herein referred to as the wire outlet end) of the cutting chamber 1 have the same principles as the turning assembly 23, the tension assembly 22 and the guide assembly 24 at the wire inlet end of the cutting chamber 1. When cutting the crystalline silicon, the cutting wire 25 moves in one direction through the wire releasing roller 21 at the first end and the wire collecting roller 21 at the second end, and then moves in the opposite direction through the wire releasing roller 21 at the second end and the wire collecting roller 21 at the first end. The wire releasing and collecting of the wire releasing roller 21 can realize the reciprocating movement of the cutting wire 25 on the cutting mechanism 11, and the wire net formed by the cutting wire 25 realizes the cutting of the crystalline silicon under the reciprocating movement.

[0051] As shown in Figure 3 In the prior art, the wire releasing roller 21 is arranged inside the main frame A, and the tension assembly 22 is arranged outside the main frame A in the wire routing mechanism 20 of the slicing machine, which makes it very inconvenient for workers to assemble the cutting wire 25, and the workers need to thread the wire in and out of the main frame A, which increases the workload and working time. The overall structure layout is changed in the present application, and the wire routing mechanism 20 is arranged inside the main frame A, as shown in Figure 1 That is, the wire releasing roller 21, the guide assembly 24, the tension assembly 22 and the turning assembly 23 are all inside the main frame A, which avoids the inconvenience caused by threading the wire, thereby improving the work efficiency.

[0052] In addition, in the prior art, the turning assembly is arranged in the cutting chamber 1, when the cutting fluid is sprayed in the cutting chamber 1, the cutting fluid is easy to flow along the cutting line 25 to the turning assembly 23, and a part of the cutting fluid is directly sprayed on the turning assembly 23, which is very unfavorable to the stability of the turning assembly 23, in addition, since a part of powder such as silicon powder exists in the cutting chamber 1, the turning assembly 23 and the cutting line 25 thereon are damaged. The turning assembly 23 is arranged in the protection chamber 3 in the present application, which avoids most of the cutting fluid from being directly sprayed on the turning assembly 23, and reduces the influence of the silicon powder on the turning assembly 23 and the cutting line 25 thereon. Since the turning assembly 23 is arranged in the protection chamber 3 and the turning assembly 23 needs to receive the cutting line 25 guided from the tension assembly 22, a threading hole (not shown in the figure) is arranged on the protection chamber 3.

[0053] In the use process of the slicing machine, the cutting line 25 needs to be guided by the guide assembly 24, the tension assembly 22 and the turning assembly 23 (the positions of the assemblies in the slicing machine are shown in Figure 1 , the guiding process is shown in Figure 2 ), the guide assembly 24, the tension assembly 22 and the turning assembly 23 all contain a wire running wheel set 210, the wire running wheel set 210 includes an outer shell 212, a rotating shaft 213 and a rotating wheel, the rotating wheel in the guide assembly 24 is a wire arranging wheel 211, the rotating wheel in the tension assembly 22 is a tension wheel 221, and the rotating wheel in the turning assembly 23 is a turning wheel 235, as shown in Figure 4 , since the rotating wheel can be any one of the wire arranging wheel 211, the tension wheel 221 and the turning wheel 235, the wire arranging wheel 211 is taken as an example for introduction below. As shown in Figure 4 , Figure 5As shown, the shell 212 of the wire arrangement wheel set 210 is fixedly arranged, the rotating shaft 213 is rotatably arranged in the shell 212, and the wire arrangement wheel 211 is fixedly arranged at the end of the rotating shaft 213. The bearing 214 is arranged between the rotating shaft 213 and the shell 212, and the bearing 214 is sleeved on the rotating shaft 213. The rotating shaft 213 specifically includes a bearing mounting portion 2131, an intermediate rotating portion 2132, and a rotating wheel mounting portion 2133 connected in sequence.

The end of the rotating shaft 213 away from the wire arrangement wheel 211 is provided with an axial end baffle 2135 connected to the mounting hole 2134 by a threaded connecting piece. The rotating shaft 213 is provided with a first end face 2132a. The first side 2141a of the inner ring 2141 of the bearing 214 abuts against the first end face 2132a. The second side 2141b of the inner ring 2141 of the bearing 214 abuts against the axial end baffle 2135. The axial end baffle 2135 and the first end face 2132a cooperate to abut against both ends of the inner ring 2141 of the bearing 214 to fix the inner ring 2141 of the bearing 214 to the rotating shaft 213. The inner side of the shell 212 is further provided with a second end face 212a. The first side 2142a of the outer ring 2142 of the bearing 214 abuts against the second end face 212a. The end of the shell 212 is further provided with an end cover 2120. The end cover 2120 is provided with a protruding circular ring 2121 inserted into the inner side of the shell 212 and abutting against the second side 2142b of the outer ring 2142 of the bearing 214. The second end face 212a of the shell 212 and the protruding circular ring 2121 cooperate to abut against both ends of the outer ring 2142 of the bearing 214 so that the outer ring 2142 can be fixed in the shell 212. In addition, the mounting rod 2122 is arranged on the side of the end cover 2120 away from the protruding circular ring 2121. The mounting rod 2122 is provided with threads (not shown in the figure). After the mounting rod 2122 passes through the corresponding mounting hole of the slicing machine, the nut 215 is screwed onto the mounting rod 2122, so that the shell 212 of the wire arrangement wheel set 210 is fixed to the corresponding position of the slicing machine.

[0054] The rotating shaft 213 in the structure is fixedly connected with the winding wheel 211, so that the winding wheel 211 rotates coaxially with the rotating shaft 213 in the rotating process of the rotating shaft 213. The rotating shaft 213 is arranged inside the shell 212, and a bearing 214 is arranged between the shell 212 and the rotating shaft 213. The bearing 214 is sleeved on the rotating shaft 213 to support the rotating shaft 213 and reduce the friction coefficient of the rotating shaft 213 in the running process. The inner ring 2141 of the bearing 214 is arranged in abutment with the rotating shaft 213, the outer ring 2142 of the bearing 214 is arranged in abutment with the shell 212, one side of the rotating shaft 213 is connected with the inner ring 2141 of the bearing 214 to make the rotating shaft 213 rotate synchronously with the inner ring 2141 of the bearing 214, and the other side of the rotating shaft 213 is fixed with the winding wheel 211 to make the winding wheel 211 rotate synchronously with the rotating shaft 213 when the rotating shaft 213 rotates. At this time, the rotating shaft 213, the winding wheel 211 and the inner ring 2141 of the bearing 214 rotate synchronously and coaxially, and the outer ring 2142 of the bearing 214 is fixed with the shell 212 to support the rotating shaft 213 and the inner ring 2141 of the bearing 214 and reduce the friction coefficient in the rotating process. Compared with the prior art in which the rotating shaft 213 is fixed and the shell 212 and the outer ring 2142 of the bearing 214 rotate to drive the winding wheel 211 to rotate, the rotating shaft 213 of the present application drives the winding wheel 211 to rotate by rotating, instead of the shell 212, so that the rotating radius can be reduced. The rotating inertia of the winding wheel set 210 can be reduced by driving the winding wheel 211 to rotate by rotating the rotating shaft 213 and the inner ring 2141 of the bearing 214, and the running resistance can be reduced, so that the working efficiency of the winding wheel set 210 is improved.

[0055] The end of the rotating shaft 213 away from the winding wheel 211 is also provided with a mounting hole 2134 and an axial end baffle 2135, the axial end baffle 2135 is connected to the mounting hole 2134 through a threaded connection, and the second side 2141b of the inner ring 2141 of the bearing 214 abuts against the axial end baffle 2135, so that the inner ring 2141 of the bearing 214 is fixedly connected with the rotating shaft 213, so that the rotating shaft 213 rotates synchronously with the inner ring 2141 of the bearing 214. The end of the shell 212 is also provided with an end cover 2120, the end cover 2120 is provided with a protruding circular ring 2121, the protruding circular ring 2121 is inserted into the inner side of the shell 212, and the protruding circular ring 2121 abuts against the second side 2142b of the outer ring 2142 of the bearing 214, so that the outer ring 2142 of the bearing 214 is fixed in the shell 212. After the above connection relationship is completed, the rotating shaft 213 and the inner ring 2141 of the bearing 214 rotate synchronously in the shell 212, and the rotating shaft 213 drives the winding wheel 211 to rotate, and the shell 212 and the outer ring 2142 of the bearing 214 are fixedly connected together to support and protect the rotating shaft 213 and the inner ring 2141 of the bearing 214. The mounting rod 2122 is arranged on the side of the end cover 2120 away from the protruding circular ring 2121, which is used to mount the wire arranging wheel set 210 on the slicing machine.

Figure 8As shown, the steering assembly 23 further comprises a slide rail 2381 fixedly arranged on the slicing machine and a slide block 2382 slidably arranged on the slide rail 2381, and the fixed support 236 is fixedly arranged on the slide block 2382. When the steering assembly 23 further comprises a height adjustment block 2370, the height adjustment block 2370 can be slidably arranged on the fixed support 236, and the sliding direction of the height adjustment block 2370 is perpendicular to the sliding direction of the fixed support 236 (i.e. Figure 8 As shown in the x direction in the middle), at this time, the steering wheel 235 is not directly arranged on the fixed support 236, but is rotatably arranged on the height adjustment block 2370, and the threading support 230 is also fixedly arranged on the height adjustment block 2370. When the steering assembly 23 further comprises an angle adjustment block 2372, the angle adjustment block 2372 is arranged on the height adjustment block 2370, and the angle adjustment block 2372 can adjust the fixed support 236 and the steering wheel 235 at a certain angle according to the needs of the cutting line 23, and the angle adjustment block 2372 can be fixed at the adjusted angle position, at this time, the steering wheel 235 is rotatably arranged on the angle adjustment block 2372, and the threading support 230 is also fixedly arranged on the angle adjustment block 2372. Preferably, the slide rail 2381 is arranged as a double guide rail 2381 to enhance the stability of the movement of the slide block 2382. In addition, in the case that the steering assembly 23 comprises the threading support 230, an isolation door 13 is arranged between the cutting chamber 1 and the outside, and the protection chamber 3 is arranged inside the isolation door 13, as shown in Figure 6 、 Figure 7 As shown, a shielding edge 12 is arranged inside the isolation door 13, the shielding edge 12 forms the top cover of the protection chamber 3, and the shielding edge 12 can be lapped on the bearing part 232 of the threading support 230, and the steering wheel 235 is arranged at a position close to the isolation door 13 inside the protection chamber 3. In addition, as shown in Figure 11 The protection chamber 3 further comprises a side water baffle 36 and a steering wheel waterproof assembly 35, the bottom of the protection chamber 3 is a water baffle 34, the side of the protection chamber 3 is the side water baffle 36, the isolation door 13 is arranged on the upper side of the side water baffle 36, the lower side of the shielding edge 13 arranged inside the isolation door 13 is further provided with the steering wheel waterproof assembly 35, and the threading support 230 is arranged between the shielding edge 13 and the steering wheel waterproof assembly 35, and the threading support 230 extends from the inside of the protection chamber 3 to the outside of the protection chamber 3, and the above arrangement makes the isolation door 13, the shielding edge 12, the steering wheel waterproof assembly 35, the water baffle 34 and the side water baffle 36 collectively surround the protection chamber 3.

[0057] Since the steering assembly 23 can guide the cutting line 25 into the cutting chamber 1, the steering assembly 23 needs to include a structure that can adjust the direction thereof, the steering assembly 23 includes a slide rail 2381 and a slide block 2382 that can slide in the length direction of the slide rail 2381 (i.e. Figure 8 the y direction shown in FIG. 13), a fixed support 236 of the steering assembly 23 is arranged on the slide block 2382, and a steering wheel 235 is arranged on the fixed support 236 in a self-rotating manner, so that the steering wheel 235 can rotate and move in the length direction of the slide rail 2381, i.e. Figure 8 the y direction shown in FIG. 13, so that the position of the steering wheel 235 can be adjusted according to the position where the cutting line 25 enters the cutting chamber 1. In order to ensure the accuracy of the position where the cutting line 25 enters the cutting chamber 1, a threading support 230 is further arranged on the fixed support 236, at this time, the cutting line 25 passing through the steering wheel 235 needs to pass through the threading slot 234 of the threading support 230 to enter the cutting chamber 1. The cutting line 25 passes through the threading slot 234 of the threading support 230, since the threading slot 234 is a fixed structure, the angle at which the cutting line 25 enters the threading slot 234 of the threading support 230 from the steering wheel 235 is fixed, and therefore, the relative position of the threading support 230 and the steering wheel 235 arranged on the fixed support 236 is fixed.

[0058] The bent fixed edge 2312 of the fixed part 231 of the threading support 230 is arranged on the fixed support 236, one end of the fixed main frame 2311 is connected with the bent fixed edge 2312, the other end of the fixed main frame 2311 is connected with the bearing part 232, so that the fixed main frame 2311 can be fixed on the fixed support 236 and can also support the bearing part 232, the stop part 233 is connected with the other end of the bearing part 232, the cutting line 25 passes through the threading slot 234 of the fixed main frame 2311, the bearing part 232 and the stop part 233 after passing through the steering wheel 235, and is then wound on the cutting mechanism 11, as shown in FIG. 14, the fixed main frame 2311 is arranged in an L shape, so that a rotating space is left for the steering wheel 235, avoiding hindering the rotation of the steering wheel 235. Figure 9 In order to more accurately adjust the direction of the threading support 230 and the steering wheel 235, the threading support 230 and the steering wheel 235 are connected to an angle adjusting block 2372, the angle adjusting block 2372 is arranged on a height adjusting block 2370, and the height adjusting block 2370 is arranged on the fixed support 236, the angle adjusting block 2372 passes through an arc-shaped hole 2371 matched therewith (as shown in FIG. 15), and the height adjusting block 2370 passes through a threaded hole 2373 matched therewith. Figure 8The angle adjusting block 2372 is fixed at one end of the height adjusting block 2370 and is angle-adjusted on the arc of the arc-shaped hole 2371, and is fixed and tightened through the bolt at the arc-shaped hole 2371 after adjustment, so as to realize the angle adjustment of the wire passing support 230 and the deflection wheel 235, so that the cutting wire 25 can be connected to the cutting mechanism 11 at a suitable angle. The height adjusting block 2370 can drive the angle adjusting block 2372 to move in the x direction through the cooperation of the bolt and the through hole, and the wire passing support 230 and the deflection wheel 235 are finally connected to the cutting mechanism 11 at a suitable position and angle after the position in the x direction is adjusted through the height adjusting block 2370 and the suitable angle is adjusted through the angle adjusting block 2372.

[0059] In addition, since the protection chamber 3 is arranged in the cutting chamber 1, and the cutting wire 25 can enter the cutting chamber 1 through the protection chamber 3, in order to reduce the cutting fluid in the cutting chamber 1 from entering the protection chamber 3, the shielding edge 12 is arranged on the isolation door 13 and arranged in the cutting chamber 1. If the shielding edge 12 is arranged without the wire passing support 230, the shielding edge 12 will hinder the cutting wire 25 from entering the cutting chamber 1, and the cutting wire 25 will also cut the shielding edge 12. The present application sets the wire passing support 230, which avoids the above problems. Since the wire passing groove 234 is arranged on the wire passing support 230, the cutting wire 25 will move along the wire passing groove 234 and will not cut the shielding edge 12. In addition, the shielding edge 12 is lapped on the bearing part 232 of the wire passing support 230, and can shield the spray of the cutting fluid from the cutting chamber 1. Since the bearing part 232 includes the flow guide slope 2321, i.e. the slope that is beneficial to the downward flow of liquid, the arrangement of the flow guide slope 2321 is beneficial to the downward flow of the cutting fluid sprayed on the support along the slope to the bottom of the cutting chamber 1. Since the stop part 233 is also arranged on the wire passing support 230, at this time, the stop part 233 can cooperate with the shielding edge 12 to further reduce the possibility of the cutting fluid entering the protection chamber 3, and can also prevent the shielding edge 12 from being shielded too much to affect the work of the cutting wire 25 and be cut by the cutting wire 25. In addition, the stop part 233 is detachably connected with the bearing part 232, the size and shape of the stop part 233 can be selected as needed, and the stop part 233 can be replaced at any time, which also reduces the cost.

[0060] Since the cutting chamber 1 of the slicing machine also needs to discharge the liquid, i.e. the cutting fluid and the powder or dust (at this time, the powder is mainly silicon powder), a drainage and exhaust unit needs to be arranged in the slicing machine, i.e. the protection chamber 3 and the cutting chamber 1 are communicated with the exhaust and liquid discharge channel. Figure 10As shown, the drainage and exhaust unit comprises a main exhaust pipeline (not shown in the figure), a main drainage pipeline (not shown in the figure), an auxiliary exhaust pipeline 33 and an auxiliary drainage pipeline 32. The first end of the main exhaust pipeline is in communication with the cutting chamber 1, and the second end is in communication with the outside. Preferably, the second end of the main exhaust pipeline is in communication with a vacuum cleaner pump. The first end of the main drainage pipeline is in communication with the cutting chamber 1, and the second end is in communication with the outside. Preferably, the second end of the main drainage pipeline is in communication with a liquid supply cylinder. The first end of the auxiliary exhaust pipeline 33 is in communication with the protection chamber 3, and the second end is in communication with the main exhaust pipeline. The first end of the auxiliary drainage pipeline 32 is in communication with the protection chamber 3, and the second end is in communication with the main drainage pipeline. (The connection between the main exhaust pipeline, the main drainage pipeline and the cutting chamber 1 is not shown in the figure, and the connection between the main drainage pipeline and the auxiliary drainage pipeline 32, and the connection between the main exhaust pipeline and the auxiliary exhaust pipeline 33 are also not shown in the figure). The gas-liquid inlet 31 is arranged in the protection chamber 3. The first end of the auxiliary exhaust pipeline 33 is in communication with the first end of the auxiliary drainage pipeline 32, and then in communication with the protection chamber 3, so that the first end of the auxiliary exhaust pipeline 33 and the first end of the auxiliary drainage pipeline 32 share one gas-liquid inlet 31. Preferably, the auxiliary drainage pipeline 32 is arranged below the auxiliary exhaust pipeline 33, and the diameter of the auxiliary exhaust pipeline 33 can be greater than the diameter of the auxiliary drainage pipeline 32. In addition, the position of the main exhaust pipeline can be higher than the position of the auxiliary exhaust pipeline 33, and the position of the main drainage pipeline can be lower than the position of the auxiliary drainage pipeline 32. In order to better drain the liquid and gas out of the protection chamber 3, the gas-liquid inlet 31 is arranged at the lowest part of the protection chamber 3. Since the bottom of the protection chamber 3 is a water baffle 34, the gas-liquid inlet 31 is arranged on the water baffle 34.

[0061] According to the slicing process of the slicer mentioned above, the wire net of the working cutting line 25 is arranged in the cutting chamber 1 and needs to be introduced into the cutting chamber 1 through the deflection wheel 235. In the prior art, the deflection wheel 235 is arranged in the cutting chamber 1, and due to the existence of cutting fluid and silicon powder in the cutting chamber 1, the deflection wheel 235 and the cutting line 25 thereon are easily damaged, and the deflection wheel 235 is also easily unstable. The present application changes the overall structure layout, and the deflection wheel 235 is arranged in the protection chamber 3. After a period of work in the cutting chamber 1, the cutting line 25 needs to be cooled and lubricated. At this time, the cutting fluid is injected into the cutting chamber 1, and after cooling the cutting line 25, most of the cutting fluid moves to the bottom of the cutting chamber 1 and is then discharged from the main liquid discharge pipeline. Another part flows along the cutting line 25 into the deflection wheel 235 and then enters the protection chamber 3. After that, the cutting fluid falls on the water baffle 34 in the protection chamber 3. Since the gas-liquid inlet 31 is arranged at the bottom of the protection chamber 3 and is connected with the water baffle 34, the cutting fluid entering the water baffle 34 will flow into the gas-liquid inlet 31 along the water baffle 34, and then flow into the auxiliary liquid discharge pipeline 32 connected with the gas-liquid inlet 31, and finally enter the main liquid discharge pipeline along the auxiliary liquid discharge pipeline 32 and be discharged from the main liquid discharge pipeline. In addition, in addition to the cutting fluid, after a period of cutting work, there are also some powders or dusts in the cutting chamber 1, for example, silicon powder generated when the cutting line 25 cuts the crystalline silicon. The following will be introduced by taking silicon powder as an example. In order to avoid affecting the work of the cutting line 25 and to avoid the cutting line 25 being worn by the silicon powder, the silicon powder needs to be discharged out of the cutting chamber 1. In addition to being discharged from the main exhaust pipeline, a part of the silicon powder in the cutting chamber 1 also flows out along the holes of the cutting line 25 and the threading support 230, and then enters the protection chamber 3, or enters the protection chamber 3 together with the cutting fluid. After the silicon powder enters the protection chamber 3, it also needs to be discharged out of the protection chamber 3, in order to avoid affecting the working setting of the cutting line 25 in the protection chamber 3 and damaging the cutting line 25. The auxiliary exhaust pipeline 33 is connected in the protection chamber 3. The silicon powder in the protection chamber 3 is sucked away by the auxiliary exhaust pipeline 33 and then discharged into the main exhaust pipeline, and then discharged out of the slicer by the vacuum dust collection pump. It should be noted that the cutting chamber 1 and the protection chamber 3 are arranged in a negative pressure state, so as to avoid the silicon powder in the cutting chamber 1 and the protection chamber 3 leaking out of the slicer and thus endangering the health of the workers and the environmental safety.

[0062] In addition, since the liquid flows downward and the silicon powder is generally suspended in the air, the auxiliary liquid discharge pipeline 32 is arranged below the main liquid discharge pipeline, i.e., the inlet of the auxiliary liquid discharge pipeline 32 is arranged below the inlet of the auxiliary gas discharge pipeline 33, so that the liquid in the protection chamber 3 flows downward to the lower part and is discharged, and the silicon powder is discharged in the auxiliary gas discharge pipeline 33 which is higher than the auxiliary liquid discharge pipeline 32. If the auxiliary gas discharge pipeline 33 is arranged below the auxiliary liquid discharge pipeline 32, the liquid is discharged from the auxiliary liquid discharge pipeline 32 which is high, and since the silicon powder is suspended, part of the silicon powder will preferentially enter the auxiliary liquid discharge pipeline 32 which is high. At this time, the auxiliary liquid discharge pipeline 32 not only contains part of the silicon powder but also contains the cutting fluid. Since the auxiliary liquid discharge pipeline 32 is connected to the pump device, the pump device is easily idled in the case that the auxiliary liquid discharge pipeline 32 contains most of the silicon powder, thereby reducing the service life of the pump device. The auxiliary gas discharge pipeline 33 arranged at the lower part has the same reason. Therefore, the inlet of the auxiliary liquid discharge pipeline 32 is arranged below the inlet of the auxiliary gas discharge pipeline 33. In addition, the pipeline diameter of the auxiliary liquid discharge pipeline 32 is arranged to be smaller than the pipeline diameter of the auxiliary gas discharge pipeline 33, which can also reduce the possibility of idling of the pump device connected to the auxiliary liquid discharge pipeline 32, and can also reduce the occupied space of the auxiliary liquid discharge pipeline 32, thereby saving materials and reducing costs.

[0063] In addition, since the liquid flows downward under the action of gravity, arranging the main liquid discharge pipeline below the auxiliary liquid discharge pipeline 32 is more conducive to the liquid in the auxiliary liquid discharge pipeline 32 flowing into the main liquid discharge pipeline. The silicon powder in powder form is suspended in the air and is more easily moved upward, so arranging the main gas discharge pipeline above the auxiliary gas discharge pipeline 33 is more conducive to the powder in the auxiliary gas discharge pipeline 33 flowing into the main gas discharge pipeline.

[0064] It should be noted that when the liquid in the main liquid discharge pipeline is not required to be recycled, the liquid in the main liquid discharge pipeline is discharged outside the slicing machine. If the liquid in the main liquid discharge pipeline is required to be recycled, the second end of the main liquid discharge pipeline is communicated with the liquid supply cylinder, so that the liquid in the main liquid discharge pipeline is recycled.

[0065] In summary, the wire arrangement mechanism 20 is arranged in the main frame A, that is, the pay-off roller 21, the guide assembly 24, the tension assembly 22 and the turning assembly 23 are arranged in the main frame A, so that the inconvenience caused by threading is avoided, and the work efficiency is improved. The rotation of the rotating shaft 213 drives the rotation of the wire arranging wheel 211, instead of the shell 212, so that the radius of rotation is reduced. The rotation of the rotating shaft 213 and the inner ring 2141 of the bearing 214 drives the rotation of the wire arranging wheel 211, so that the moment of inertia of the wire arranging wheel set 210 is reduced, and the running resistance is reduced, so that the work efficiency of the wire arranging wheel set 210 is improved. The shaft end baffle 2135 is connected to the mounting hole 2134 by a threaded connection, so as to fixedly connect the inner ring 2141 of the bearing 214 and the rotating shaft 213, so that the rotating shaft 213 and the inner ring 2141 of the bearing 214 rotate synchronously. The protruding ring 2121 abuts against the second side 2142b of the outer ring 2142 of the bearing 214, so as to fix the outer ring 2142 of the bearing 214 in the shell 212. The rotating shaft 213 and the inner ring 2141 of the bearing 214 rotate synchronously in the shell 212, and the rotating shaft 213 drives the wire arranging wheel 211 to rotate. The shell 212 and the outer ring 2142 of the bearing 214 are fixedly connected together, so as to support and protect the rotating shaft 213 and the inner ring 2141 of the bearing 214.

[0066] Since the turning assembly 23 can guide the cutting wire 25 into the cutting chamber 1, the turning assembly 23 needs to include a structure that can adjust the direction thereof. The turning assembly 23 includes a sliding rail 2381 and a sliding block 2382, the sliding block 2382 can slide in the length direction (y direction) of the sliding rail 2381, a fixed support 236 of the turning assembly 23 is arranged on the sliding block 2382, and a turning wheel 235 is arranged on the fixed support 236 in a self-rotating manner. The turning wheel 235 can rotate and move in the length direction of the sliding rail 2381 at the same time, so that the position of the turning wheel 235 can be adjusted according to the position of the cutting wire 25 entering the cutting chamber 1. In order to ensure the accuracy of the position of the cutting wire 25 entering the cutting chamber 1, a threading support 230 is further arranged on the fixed support 236. After passing through the turning wheel 235, the cutting wire 25 is wound on the cutting mechanism 11 through the threading groove 234 of the fixed main frame 2311, the bearing part 232 and the stop part 233 of the threading support 230. In order to reduce the cutting fluid in the cutting chamber 1 from entering the protection chamber 3, a shielding edge 12 is arranged on the isolation door 13, and the shielding edge 12 is arranged in the cutting chamber 1. If the shielding edge 12 is arranged without the threading support 230, the shielding edge 12 will hinder the cutting wire 25 from entering the cutting chamber 1, and the cutting wire 25 will be cut by the shielding edge 12. The arrangement of the threading support 230 avoids the above problems.

[0067] When the working in the cutting chamber 1 is carried out for a period of time, the cutting line 25 needs to be cooled and lubricated, at this time, the cutting fluid is injected into the cutting chamber 1, a part of the cutting fluid flows along the cutting line 25 onto the deflector 235 and then enters the protection chamber 3, and then falls onto the water baffle 34 in the protection chamber 3. Since the gas-liquid inlet 31 is arranged at the bottom of the protection chamber 3 and is connected with the water baffle 34, the cutting fluid entering the water baffle 34 flows along the water baffle 34 into the gas-liquid inlet 31, and then flows into the auxiliary liquid discharge pipeline 32 connected with the gas-liquid inlet 31, and finally enters the main liquid discharge pipeline along the auxiliary liquid discharge pipeline 32 and is discharged from the main liquid discharge pipeline. In addition, in addition to the cutting fluid, there are also some silicon powder generated when the cutting line 25 cuts the crystalline silicon in the cutting chamber 1, a part of the silicon powder flows out of the hole of the cutting line 25 and enters the protection chamber 3, or enters the protection chamber 3 together with the cutting fluid. In order to avoid the influence of the silicon powder on the working of the cutting line 25 in the protection chamber 3, the auxiliary gas discharge pipeline 33 is connected in the protection chamber 3, and the silicon powder is sucked away by the auxiliary gas discharge pipeline 33 and discharged into the main gas discharge pipeline and then discharged out of the slicing machine.

Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will all fall within the protection scope of the present application.
