Technical field

The present application relates to a hard and brittle material cutting equipment technology, and in particular to a wire saw unit and a wire cutting machine.

Background technique

A slicer is a device that cuts a rod of hard and brittle material into thin slices through a cutting wire. The current slicing machine includes: main cutting roller, steering mechanism, tension mechanism, wire arrangement mechanism and wire retracting and unwinding mechanism. After the cutting wire is wound out from the wire retracting and unwinding mechanism, it passes through the wire arranging mechanism, tension mechanism and steering mechanism and enters the main cutting roller. The cutting wire is wound around the main cutting roller multiple times to form a cutting wire network for cutting hard and brittle material rods. The wire arrangement mechanism evenly winds the cutting wire around the retracting and unwinding mechanism or evenly releases the cutting wire wound on the retracting and unwinding mechanism during movement; the tension wheel in the tension mechanism is used to adjust the tension of the cutting wire; the steering mechanism is used Change the direction of the cutting line to lead the cutting line wound out of the main cutting roller to the tension mechanism. Usually, there are multiple rollers between the above-mentioned mechanisms to support the cutting line.

In traditional slicing machines, the cutting line needs to pass through more than 6 wire wheels when moving back and forth between the main cutting roller and the wire retracting and unwinding mechanism. Too many wire wheels will lead to poor coplanarity between the wire wheels and the rotation of the wire wheels. Factors such as inertia and rotational resistance will adversely affect the stability of the cutting wire tension. Too many wire wheels will also cause a large additional tension on the entire slicer, which will lead to larger tension fluctuations in the cutting line, further reducing the stability of the tension.

Normally, the tension that the tension mechanism can provide to the cutting wire = the static breaking force of the cutting wire - the amplitude of the tension fluctuation. If the tension fluctuation amplitude is too large, the tension that the tension mechanism can provide to the cutting wire is reduced, and the tension that the tension mechanism can provide to the cutting wire is reduced. The reduction of the cutting wire tension will reduce the cutting ability of the cutting wire, ultimately affecting the cutting efficiency.

In addition, the cutting wire is gradually becoming thinner, the breaking tension of the cutting wire is getting smaller and smaller, and the proportion of tension fluctuations caused by factors such as wheel inertia, rotational resistance and poor coplanarity is getting higher and higher, which affects the control accuracy of the tension mechanism. The requirements are getting higher and higher. If the tension fluctuation amplitude and additional tension caused by the aforementioned guide wheel factors remain unchanged, the cutting ability of the cutting wire will be further reduced, making it difficult to ensure cutting quality and hindering the development of thinning cutting wires.

Detailed ways

In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application. This is not an exhaustive list of all embodiments. It should be noted that, as long as there is no conflict, the embodiments and features in the embodiments of this application can be combined with each other.

This embodiment provides a wire saw unit that can be used in a wire cutting machine to cut workpieces. The workpiece can be a hard and brittle material rod such as single crystal silicon material rod, polycrystalline silicon material rod, sapphire rod, magnetic material rod, etc. This embodiment takes a silicon material rod as an example (hereinafter referred to as: silicon rod) to describe the wire saw unit and the wire cutting machine in detail. Those skilled in the art can also apply the solution provided in this embodiment to cutting rods of other materials.

The wire cutting machine can be a cutting machine, a squaring machine or a slicing machine. The cutting machine is used to cut longer silicon rods into shorter ones; the squaring machine is used to cut the circular cross-section into cross-sections. A silicon rod with a rectangular cross section; a microtome is used to cut a silicon rod with a rectangular cross section into thin slices. This embodiment takes a slicer as an example to describe the wire saw unit in detail. Those skilled in the art can also apply the solution provided in this embodiment to other wire cutting machines.

Figure 1 is a schematic structural diagram of a slicer provided by an embodiment of the present application. Figure 2 is an axial view of the slicer provided by an embodiment of the present application. Figure 3 is a cutting mechanism, tensioning mechanism and retraction mechanism of the slicer provided by an embodiment of the present application. Simplified view of the pay-off mechanism. As shown in Figures 1 and 2, this embodiment provides a wire saw unit that can be applied to a slicer. The wire saw unit includes: a cutting mechanism 1 and a wire retracting and unwinding mechanism 3, both of which are arranged on the cutting frame 4.

A cutting wire is wound around the cutting mechanism 1 for cutting the silicon rod. In one embodiment, the cutting mechanism 1 includes at least two cutting rotating parts. For the cutting machine and the squarer, the cutting rotating part is specifically the cutting wire wheel; for the slicing machine, the cutting rotating part is specifically the cutting main roller 11. Cutting wires 7 are wound around at least two cutting rotating parts, and the cutting line segments between the cutting rotating parts serve as a cutting wire network.

The cutting frame is also provided with a feeding mechanism 5. The silicon rod 6 is fixed on the feeding mechanism 5. The feeding mechanism 5 drives the silicon rod 6 to move toward the cutting wire network, and the cutting wire network cuts the silicon rod 6. Taking the slicing machine shown in Figures 1 to 3 as an example, the three cutting main rollers 11 are parallel and arranged in a triangle. The feeding mechanism 5 drives the silicon rod 6 to move downward and is wound around the top of the two upper cutting main rollers 11. Cut the silicon rod 6 with the cutting line, and cut the silicon rod 6 into thin slices. The slicer shown in Figures 1 to 3 is only an example. The number and arrangement of the main cutting rollers 11 can also be in other forms, and the driving direction of the feeding mechanism 5 can also be upward movement or horizontal movement.

The wire saw unit also includes a tension mechanism 2. The tension mechanism 2 includes a tension wheel for adjusting the tension of the cutting wire. The tension wheel is arranged corresponding to the cutting mechanism, so that the cutting wire wound out by the cutting mechanism is guided to the tension wheel, or the tension wheel is wound out. The cutting line is guided to the cutting mechanism.

The retracting and unwinding mechanism 3 includes a retracting and unwinding roller for storing or releasing the cutting wire, so that the cutting wire reciprocates between the retracting and unwinding mechanism, the tension mechanism and the cutting mechanism, forming a single line reciprocating movement to cut the silicon rod.

The take-up and pay-off mechanism 3 also includes: a take-up and pay-off line rotation driver for driving the take-up and pay-off line roller to rotate circumferentially, and a take-up and pay-off line moving driver for driving the take-up and pay-off line roller to reciprocate in the axial direction, so as to realize the retract and pay-off line operation. During the circumferential rotation and axial reciprocating movement of the roller, the cutting line wound out by the cutting mechanism is stored in the retracting and unwinding roller, or the cutting line released by the retracting and unwinding roller is wound around the cutting mechanism.

The technical solution provided by this embodiment adopts a cutting mechanism, a tension mechanism and a retracting and unwinding mechanism. The cutting mechanism is wound with a cutting wire; the tension mechanism includes a tension wheel for adjusting the tension of the cutting wire, and the tension wheel corresponds to the cutting mechanism. It is arranged so that the cutting wire wound by the cutting mechanism is guided to the tension wheel, or the cutting wire wound by the tension wheel is guided to the cutting mechanism; the wire retracting and unwinding mechanism includes a retracting and unwinding wire roller for storing or releasing the cutting wire, so that the cutting wire can be The thread moves back and forth between the retracting and unwinding mechanism, the tensioning mechanism and the cutting mechanism. In the above scheme, the reversing mechanism in the traditional scheme is no longer needed between the tension mechanism and the cutting mechanism. On the one hand, it reduces the number of parts and the number of maintenance times, reduces the installation complexity and the number of maintenance times, and also helps to reduce the weight; on the other hand, The cutting line no longer passes through the reversing wheel, which reduces the number of wire wheels that the cutting line passes through. It also overcomes the problem of low tension stability in the traditional solution due to factors such as the coplanarity of each wire wheel, the moment of inertia of the wire wheels, and the rotational resistance of the wire wheels. , reducing the fluctuation amplitude of the cutting line tension, thereby reducing the additional tension of the cutting line, increasing the tension that the tension mechanism can apply to cutting, improving the cutting ability of the cutting line, and improving the stability of the wire mesh tension so that the cutting line The tension meets cutting requirements, guarantees cutting quality and efficiency, thereby improving yield and production efficiency, meeting the requirements for thinning cutting lines, reducing silicon loss, and improving silicon rod utilization.

Specifically, the cross section of the main cutting roller 11 is circular, and its outer peripheral surface is provided with a plurality of cutting wire grooves for accommodating the cutting wire. From the cutting wire groove of one cutting main roller 11 to the cutting wire groove of the other cutting main roller 11, it is wound in sequence one by one to form a cutting wire network. The cutting wire can be wound into the cutting mechanism 1 from any cutting wire groove on any cutting main roller 11, or wound out of the cutting mechanism 1. The cutting wire groove that winds into or out of the cutting wire is called a target cutting wire groove. For example: For the three-roller structure shown in Figure 3, the cutting line is wound into the cutting main roller 11 from the target cutting line groove at one end of the lower cutting main roller 11, and then wound around the three main cutting rollers 11 clockwise or counterclockwise. , and finally wind out from the target cutting wire groove at the other end of the lower cutting main roller 11.

On the basis of the above technical solution, a tension mechanism can also be used. The tension mechanism has a tension wheel. The cutting line between the cutting mechanism and the retracting and unwinding mechanism passes through the tension wheel. The tension wheel is used to adjust the tension of the cutting line.

On this basis, a reversing mechanism can also be used. The reversing mechanism includes a reversing wheel, and the cutting line between the cutting mechanism and the tension mechanism passes through the reversing wheel; the reversing wheel is arranged corresponding to the cutting mechanism, for example, on the side of the main cutting roller, so that the cutting line around the main cutting roller can The wire is guided to the reversing wheel, or the cutting wire wound by the reversing wheel is guided to the main cutting roller.

For the solution with a tension mechanism, a reversing mechanism and a retracting and unwinding mechanism, the reversing mechanism is set on the side of the main cutting roller. The tension mechanism can be set on one end of the axial direction of the main cutting roller according to the traditional solution. The retracting and unwinding mechanism is set on the tension below or above the mechanism. Alternatively, the tension mechanism and the retracting and unwinding mechanism can also be arranged in the area below the main cutting roller.

This embodiment also provides an implementation: the tension mechanism 2 is arranged on the side of the cutting mechanism 1, and specifically includes: a tension wheel 21 and a tension driver 22 for driving the tension wheel 21 to swing (as shown in Figure 4). The tension wheel 21 is provided with a tension groove for accommodating the cutting wire. The tension groove corresponds to the target cutting wire groove on the main cutting roller 11, so that the cutting wire 7 can be wound out from one side of the tension wheel 21 and directly enter the main cutting roller. 11 on the cut wire trough. Specifically, the tension line groove corresponds to the target cutting line groove on the cutting main roller 11, so that the cutting line wound out from the target cutting line groove is guided to the tension line groove, or the cutting line wound out from the tension line groove is guided to the target. Cutting wire ducting.

In addition, the swing of the tension wheel 21 can adjust the tension of the cutting wire. Only when the cutting wire maintains a certain tension can the silicon rod be cut. That is to say, in this solution, only the tension mechanism 2 and the wire retracting and unwinding mechanism 3 are needed, and the cutting wire can be reciprocated between the tension mechanism 2, the wire retracting and unwinding mechanism 3 and the cutting mechanism 1 to achieve cutting.

Figure 4 is a schematic structural diagram corresponding to the wire groove of the cutting main roller and the tension wheel in the wire saw unit provided by the embodiment of the present application. Figure 4 is a top view. As shown in FIG. 4 , the main cutting roller 11 is provided with a plurality of cutting wire grooves 111 , and the tension wheel 21 is provided with a tension wire groove 211 . The cutting wire trough 111 and the tension wire trough 211 are provided correspondingly, so that the cutting wire can be wound out of the cutting wire trough 111 and directly wound into the tension wire trough 211, or the cutting wire can be wound directly into the cutting wire trough 111 after being wound out of the tension wire trough 211.

As shown in FIGS. 7 and 8 , the take-up and pay-off mechanism 3 includes a take-up and pay-off roller 31 and a take-up and pay-off rotational driver. The take-up and pay-off rotation driver is used to drive the take-up and pay-off roller 31 to rotate. The cutting wire 7 wound out from the other side of the tension wheel 21 is wound and stored on the take-up and pay-off roller 31 , and the cutting wire on the take-up and pay-off roller 31 can also be released and wound on the tension wheel 21 .

In the above scheme, the cutting wire wound on the retracting and unwinding roller 31 is wound out and directly enters the main cutting roller 11 through the tension wheel 21; the cutting wire wound out from the main cutting roller 11 directly passes through the tension wheel 21 and is then stored in the retracting and unwinding roller 31. Line roller 31. The tension wheel 21 plays the role of the reversing wheel mechanism in the traditional solution, that is, changing the direction of the cutting wire wound out from the main cutting roller, and guiding the cutting wire to wind into the retracting and unwinding wire roller.

In the above scheme, the reversing mechanism in the traditional scheme is no longer needed between the tension mechanism and the cutting mechanism. On the one hand, it reduces the number of parts and the number of maintenance times, reduces the installation complexity and the number of maintenance times, and also helps to reduce the weight; on the other hand, The cutting line no longer passes through the reversing wheel, further reducing the number of wire wheels that the cutting line passes through, further ensuring cutting quality and efficiency, thereby improving yield and production efficiency.

The cutting wire moves back and forth between the retracting and unwinding mechanism 3, the tension mechanism 2 and the cutting mechanism 1 to achieve cutting of the silicon rod.

The axis of the main cutting roller 11 and the axis of the tension wheel 21 may or may not be parallel. Regarding the corresponding relationship between the above-mentioned cutting wire trough 111 and the tension wire trough 211, there can be many forms:

1. The plane formed by the cutting wire trough 111 (that is, the target cutting wire trough) entering and exiting the cutting line is parallel to the plane formed by the tension wire trough 211. In this case, the target cutting wire trough and the tension wire trough 211 can be directly opposite (as shown in Figure 4), or they can be staggered, as long as it can ensure that the cutting wire can be wound around the target cutting wire trough and the tension wire trough 211 and between them. You can move smoothly between them.

2. The plane formed by the cutting wire trough 111 (that is, the target cutting wire trough) entering and exiting the cutting line is not parallel to the plane formed by the tension wire trough 211. In this case, the ends of the target cutting wire trough and the tension wire trough 211 that are close to each other are aligned, or they can be staggered, as long as it can be ensured that the cutting wire can be wound around the target cutting wire trough and the tension wire trough 211 and smoothly between them. Just move it.

The above two situations are the positions of the tension wheel 21 when it is in a static state, as shown in Figure 4. During the operation of the slicer, the tension wheel 21 still swings to adapt to changes in the cutting line tension, as shown in Figures 5 and 6.

There can be one tension line groove on the tension wheel 21, or there can be more than two tension line grooves. When the tension wheel 21 is provided with multiple tension wire grooves, the cutting wire grooves in this embodiment refer to the tension wire grooves around which cutting wires are wound.

In the top view shown in Figure 4, the axis of the tension wheel 21 extends along the horizontal direction, or the axis of the tension wheel 21 can also be at a certain angle with the horizontal plane (as shown in Figures 5 and 6), and the angle can be an acute angle or is a right angle. When it is a right angle, the tension wheel 21 The axis extends in the vertical direction. One implementation method is: the plane where the tension line groove 211 is located is perpendicular to the axis of the tension wheel 21, so the plane where the tension line groove 211 is located on the tension wheel 21 and the plane where the cutting line groove 111 of the cutting line enters and exits the cutting main roller 11 is located. The included angle is [0, 90°].

The difference between FIG. 5 and FIG. 6 is that the cutting wire 7 winds into or out of the cutting mechanism 1 from different cutting wire grooves 111 .

Furthermore, the tension mechanism 2 further includes a tension wheel driving mechanism for driving the tension wheel 21 to move along the axis of the main cutting roller 11 so that the tension groove 211 can move to correspond to different cutting grooves 111 .

Based on the above technical solution, a pulley can be provided between the tension wheel 21 and the wire take-up and pay-off roller 31 to guide, change direction and support the cutting line between the tension wheel 21 and the wire take-up and pay-off roller 31 .

Alternatively, a wire arrangement mechanism can be provided between the wire retracting and unwinding mechanism 3 and the tension mechanism 2. The wire arranging mechanism is used to guide the cutting wire and wind it around the main cutting roller.

The axis of the tension wheel 21 and the axis of the take-up and pay-off roller 31 can be parallel, perpendicular, or at other angles.

This embodiment provides an implementation method: the tension groove 211 of the tension wheel 21 is aligned with the take-up and pay-off roller 31, that is, the plane of the tension groove 211 faces the projection of the take-up and pay-off mechanism on the take-up and pay-off roller 31, so that The cutting wire wound out from the tension wheel 21 directly enters the take-up and pay-off roller 31. Specifically, the cutting wire wound out of the tension line trough is guided to the take-up and pay-off roller 31 through the tension wheel 21, or the take-up and pay-off roller 31 is wound out. The cutting wire is directed to the tension line trough. The cutting line can be stored in the retracting and unwinding line roller 31.

As shown in Figure 7, the axis of the tension wheel 21 is parallel to the axis of the take-up and pay-off roller 31; or as shown in Figure 8, the axis of the tension wheel 21 is not parallel to the axis of the take-up and pay-off roller 31, so that the cutting line is wound obliquely on the take-up and pay-off roller 31.

The above-mentioned retracting and unwinding roller 31 is also arranged on the side of the main cutting roller 11. Viewed from the axis of the main cutting roller 11, the angle between the axis of the retracting and unwinding roller 31 and the axis of the main cutting roller 11 is [0, 90 °]. In the scheme shown in FIG. 3 , the axis of the retracting and unwinding roller 31 is parallel to the axis of the main cutting roller 11 .

The axis of the take-up and pay-off roller 31 and the plane where the tension line groove in the tension wheel 21 is located can be parallel, perpendicular, or at an acute angle. The plane where the tension line groove is located can be perpendicular to the axial direction of the tension wheel 21, or can be at a certain angle. In Figure 7, it can be intuitively seen that the axis of the take-up and pay-off roller 31 is parallel to the axis of the tension wheel 21. When the plane where the tension line groove is located is perpendicular to the axial direction of the tension wheel 21, the plane where the tension line groove is located is parallel to the axis of the tension wheel 21. The axis of the roller 31 is vertical; in Figure 8, the axis of the retracting and unwinding roller 31 is not parallel to the axis of the tension wheel 21. When the plane where the tension line groove is located is perpendicular to the axial direction of the tension wheel 21, the plane where the tension line groove is located is parallel to the axis of the tension wheel 21. The axis of the take-up and pay-off roller 31 forms an acute angle.

Another embodiment: the retracting and unwinding mechanism 3 also includes: a retracting and unwinding wire moving driver for driving the retracting and unwinding roller 31 to reciprocate along its axial direction, so that the cutting wire wound out from the tension wheel is evenly stored in the retracting wire. Pay-off roller, or evenly release the cutting line stored in the pay-off roller to the tension wheel. Equivalently, the wire retracting and unwinding mechanism 3 also has the function of arranging wires, so it is no longer necessary to use the wire arranging mechanism in the traditional solution, further reducing the number of wire wheels through which the cutting wire passes, thereby reducing the additional tension of the cutting wire, which is especially suitable for If the cutting line is long, make sure that the cutting line is wound neatly on the retracting and unwinding roller so that it can be easily wound out next time without getting knotted.

This embodiment provides a specific implementation: the number of tension mechanisms 2 is two, one tension mechanism 2 corresponds to one target cutting slot in the cutting mechanism 1, and the other tension mechanism 2 corresponds to another target in the cutting mechanism 1. Cutting wire trough corresponding. The number of the wire retracting and unwinding mechanisms 3 is two, which correspond to the tension mechanism 2 one-to-one. The two wire retracting and unwinding mechanisms 3 alternately take up and pay out the wire, so that the cutting line can be moved between the two wire retracting and unwinding mechanisms 3 and the two tension mechanisms. 2 and the cutting mechanism 1 move back and forth, and the two target cutting wire troughs alternately exit and enter the wire.

Figure 35 is a schematic structural diagram of the wire retracting and releasing mechanism provided by the embodiment of the present application. As shown in FIG. 35 , the wire retracting and unwinding mechanism provided by this embodiment includes: a wire retracting and unwinding roller 31 , a retracting and unwinding wire rotation drive assembly 32 , and a retracting and unwinding wire moving driving assembly 33 .

The cutting wire is wound around the peripheral surface of the wire retracting and unwinding roller 31, and the wire retracting and unwinding roller 31 is used to store the cutting wire and can also release the cutting wire.

Figure 36 is a schematic structural diagram of the rotating drive assembly of the retracting and unwinding wire in the retracting and unwinding mechanism provided by the embodiment of the present application. As shown in Figure 36, the retracting and unwinding wire rotation drive assembly 32 includes: a rotation motor 321, an adapter flange 322, a bearing box 323, and a tensioning screw 324. The tightening screw 324 passes through the bearing box 323, the take-up and pay-off roller 31, and the adapter flange 322 in sequence and is connected to the rotating motor 321.

The adapter flange 322 is connected between one end of the take-up and pay-off roller 31 and the rotating motor 321 . The bearing box 323 is provided at the other end of the take-up and pay-off roller 31 . The bearing box 323 is provided with a bearing for rolling support of the take-up and pay-off roller 31 . The tightening screw 324 starts from one side of the bearing box 323, passes through the bearing box 323, the take-up and pay-off roller 31, the adapter flange 322 in sequence, and is connected to the rotating motor 321 through threads. The tightening screw 324 rotates in the tightening direction, so that The tightening screw 324 has a pressing force that moves toward the rotating motor 321, thereby exerting a pressing force on the bearing box 323, the take-up and pay-off roller 31, the adapter flange 322 and is connected to the rotating motor 321.

One specific way: Figure 37 is an exploded view of the connection between the take-up and pay-off wire rotation drive assembly and the take-up and pay-off roller in the take-up and pay-off mechanism provided by the embodiment of the present application. As shown in Figure 37, a screw pressing assembly is further used to cooperate with the tightening screw 324 to ensure that the tightening screw 324 reaches the maximum tightening efficiency. Specifically, the screw pressing assembly includes: axial pressure plate 325, disc spring 326, baffle 327, and elastic retaining ring 328. Among them, the axial pressure plate 325 has a cylindrical structure, and one axial end thereof is connected to the retracting and unwinding roller 31. The disc spring 326, the baffle 327 and the elastic retaining ring 328 are sequentially installed into the axial pressure plate 325, and the elastic retaining ring 328 is embedded in the axial pressure plate 325. In the annular groove of the inner wall, the disc spring 326 and the baffle 327 are limited in the shaft pressure plate to avoid falling. The number of the disc springs 326 is two, and the installation directions are opposite, and are used to provide elastic preload force along the axial direction.

The tightening screw rod 324 passes through the elastic retaining ring 328, the baffle 327, the two disc springs 326, the axial pressure plate 325, and the adapter flange 322 in sequence, and then penetrates into the threaded sleeve 329, which is fixed to the rotating motor 321. The pre-tightening force acting on the take-up and pay-off roller can be controlled by screwing the thread on the tensioning screw 324. Each component connected by the tightening screw 324 is fixed together and rotates as a whole under the driving of the rotating motor 321 .

The above-mentioned rotating motor 321 can be fixed on the retracting and unwinding line moving drive assembly 33. The retracting and unwinding line moving driving assembly 33 drives the rotating motor 321 to move in the axial direction, and drives the retracting and unwinding line roller 31 to move in the axial direction. In this solution, the other end of the take-up and pay-off roller 31 is not supported and is in a cantilevered state, which will cause the output shaft of the rotating motor 321 to receive a large bending moment, which may easily cause the coaxiality between the take-up and pay-off roller 31 and the rotating motor 321. Poor.

Alternatively, in this embodiment, a rotating motor base may be used to simultaneously support and fix the retracting and unwinding wire roller 31 and the retracting and unwinding wire rotating drive assembly 32. The rotating motor base is fixed to the retracting and unwinding wire moving drive assembly 33, so that the retracting and unwinding wires can be moved and driven. The assembly 33 drives the take-up and pay-off wire roller 31 and the take-up and pay-off wire rotation drive assembly 32 to reciprocate in the axial direction synchronously. Moreover, both the take-up and pay-off roller 31 and the take-up and pay-off rotating drive assembly 32 are supported by the rotating motor base 34, which is beneficial to ensuring the coaxiality between the take-up and pay-off roller 31 and the rotating motor 321.

Figure 38 is a schematic structural diagram of the rotating motor base in the wire retracting and unwinding mechanism provided by the embodiment of the present application. As shown in Figure 38, one embodiment is: the rotating motor base 34 has two support arms 341, which are respectively supported on the adapter flange 322 and the bearing box 323, and are respectively supported from both axial ends of the take-up and pay-off roller 31. . Specifically, the rotating motor base 34 has a bottom bracket, one end of which is provided with a support arm 341 for supporting the bearing box 323, and a middle part of which is provided with a support arm 341 for supporting the adapter flange 322. The rotating motor 321 is disposed at the end of the bearing box 323 away from the support arm 341 .

The support arm 341 is perpendicular to the bottom bracket, and the support arm 341 has a plate-like structure. The two support arms 341 are parallel. The support arm 341 at the end has a through hole for the bearing box 323 to pass through, and the support arm 341 at the middle has a through hole for the adapter flange 322 to pass through.

For the above-mentioned bearing box 323, this embodiment also provides a specific method:

Figure 39 is a schematic structural diagram of the bearing box in the wire retracting and unwinding mechanism provided by the embodiment of the present application. Figure 40 is an exploded view of the bearing box in the wire retracting and unwinding mechanism provided by the embodiment of the present application. Figure 41 is a schematic diagram of the bearing box in the retracting and unwinding mechanism provided by the embodiment of the present application. Cross-sectional view of the bearing housing in the pay-off mechanism. As shown in Figures 39 to 41, the bearing box 323 includes: a bearing sleeve 3231, a bearing 3232, a bearing end cover 3233, a driving shaft 3234 and a locking nut 3235.

Among them, one axial end surface of the bearing sleeve 3231 is provided with an opening for the lock nut 3235 to pass through, and the other axial end of the bearing sleeve 3231 is connected to the bearing end cover 3233 through bolts. The bearing end cover 3233 and the bearing sleeve 3231 form a receiving cavity.

The bearing 3232 is arranged in the bearing sleeve 3231. One end of the bearing 3232 is provided with a first oil retaining ring 3236 and an adjusting gasket 3237, and the other end is provided with a second oil retaining ring 3238 and an O-ring 3239. The adjusting gasket 3237, the first oil slinger 3236, the bearing 3232, the second oil slinger 3238 and the O-ring 3239 are installed into the accommodation cavity in sequence. The first oil retaining ring 3236 and the second oil retaining ring 3238 can prevent the lubricating oil in the bearing from being thrown out during high-speed rotation to ensure the lubrication effect. The adjustment shim 3237 is used for the installation error and clearance of the trolley, and is also used to fix the outer ring of the bearing to limit its axial movement.

The driving shaft 3234 has a shaft body 32341 at one end and a shaft disk 32342 at the other end. The shaft disk 32342 is connected to the take-up and pay-off line roller 31 . The shaft body 32341 has a certain length along the axial direction. The bearing end cover 3233 is provided with an opening for the shaft body 32341 to pass through, and the shaft body 32341 penetrates into the inner ring of the bearing 3232 from the opening of the bearing end cover 3233.

Furthermore, the end surface of the shaft plate 32342 is a bevel, and the hole at the end of the take-up and pay-off roller 31 is clamped, so that the bearing box axially resists the take-up and pay-off roller 31 under the action of the pre-tightening force, thereby realizing the retraction and release. The line roller 31 is fixed.

The driving shaft 3234 is provided with a central hole extending in the axial direction, and the tightening screw 324 passes through the central hole. The shaft body 32341, which is equivalent to the driving shaft 3234, is inserted between the tightening screw 324 and the inner ring of the bearing 3232. The shaft body 32341 extends until it is threaded and fixed with the locking nut 3235, and the components in the bearing sleeve are limited from both axial ends.

The bearing end cover 3233 is provided with a sealing groove, and a labyrinth oil seal is installed in the small shaft diameter gap with the driving shaft 3234, and cooperates with the O-ring seal 3239 and the oil retaining ring to achieve a good sealing effect.

When the rotating motor 321 drives the take-up and pay-off roller 31 to rotate at high speed, the driving shaft 3234 and the bearing 3232 rotate synchronously with the take-up and pay-off roller 31 at high speed.

On the basis of the above technical solution, this embodiment provides an implementation method of the retracting and unwinding line moving drive assembly 33:

Figure 42 is a schematic structural diagram of the moving drive assembly of the retracting and unwinding wire in the retracting and unwinding mechanism provided by the embodiment of the present application. Figure 43 is a schematic structural diagram of the cooperation between the screw and the nut in Figure 42. As shown in Figures 42 and 43, the retracting and unwinding line moving drive assembly 33 includes: a sliding table 331, a driving motor 332, a lead screw 333, a moving nut 334, a linear guide rail 335, and a slide block 336.

Among them, the driving motor 332 is disposed on the sliding table 331, and the output end of the driving motor 332 is connected to the screw 333 for driving the screw 333 to rotate. The moving nut 334 is threaded with the lead screw 333 . The retracting and unwinding wire rotation driving assembly 32 is connected to the moving nut 334 through the rotating motor base 34 and moves synchronously. The retracting and unwinding wire rotation drive assembly 32 is connected to the slide block 336 through the rotation motor base 34, and slides synchronously relative to the linear guide rail 335.

Through the cooperation between the screw and the nut, it has high movement adjustment accuracy and can finely control the moving distance of the retracting and unwinding roller, so that the cutting line can be evenly wound around the retracting and unwinding roller.

Further, the retracting and unwinding mechanism also includes: a bottom frame, which can be fixed on the frame of the slicer. The take-up and pay-off wire roller 31, the take-up and pay-off wire rotation drive assembly 32 and the take-up and pay-off wire moving drive assembly 33 move as a whole in the axial direction relative to the chassis. When the maximum stroke of the above-mentioned take-up and pay-off wire moving drive assembly 33 cannot meet the displacement requirement of the take-up and pay-off roller, the take-up and pay-off mechanism can be adjusted to move relative to the chassis, thereby increasing the axial movement stroke of the take-up and pay-off roller.

Specifically, the base frame is provided with a guide groove extending along the axial direction. Correspondingly, a guide wheel 35 is provided at the bottom of the retracting and unwinding line moving drive assembly 33, and the guide wheel 35 can roll along the guide groove to reduce friction.

Further, a fixed support component is provided under the chassis. After the retracting and unwinding wire roller 31, the retracting and unwinding wire rotation drive assembly 32 and the retracting and unwinding wire moving drive assembly 33 are moved into place as a whole, they are fixed so that they can be retracted and released during the cutting operation. The wire roller 31, the retracting and unwinding wire rotation driving assembly 32, and the retracting and unwinding wire moving driving assembly 33 are all kept fixed relative to the cutting frame.

Based on the above technical solution, this embodiment provides several implementation modes:

The two sets of wire retracting and unwinding mechanisms 3 may be located on both sides of the cutting mechanism 1, or both may be located on the same side of the cutting mechanism 1. The two sets of tension mechanisms 2 can be located on both sides of the cutting mechanism 1 respectively, or they can both be located on the same side of the cutting mechanism 1 .

For two sets of retracting and unwinding mechanisms 3 located on the same side of the cutting mechanism 1, and two sets of tension mechanisms 2 located on both sides of the cutting mechanism 1 respectively, this embodiment provides two implementation methods:

Example one:

Figure 9 is a first layout schematic diagram of a wire saw unit provided by an embodiment of the present application. As shown in Figure 9, the cutting mechanism 1 includes at least three main cutting rollers 11, of which two main cutting rollers 11 are on the upper side and at least one main cutting roller 11 is on the lower side. One cutting main roller 11 can be used below, and a total of three cutting main rollers 11 form a triangle; or two cutting main rollers 11 can be used below, and a total of four cutting main rollers 11 form a rectangle or trapezoid. Figure 9 shows two cutting main rollers 11 on top and one cutting main roller 11 on the bottom forming a triangle. The silicon rod moves downward from above, and the cutting line between the two upper cutting main rollers 11 cuts the silicon rod.

In one state, the cutting line 7 cuts the top of the main roller 11 from above or winds out or in from the bottom of the main roller 11 . In Figure 9, the cutting line 7 winds out or in from the bottom of the main cutting roller 11. From the moving direction of the cutting line, the cutting line 7 winds into the cutting structure 1 from the bottom of the main cutting roller 11 and from below. The bottom of the cutting main roller 11 winds out of the cutting structure 1; when the cutting line moves in the reverse direction, the cutting line 7 winds into the cutting structure 1 from the bottom of the cutting main roller 11, and winds out of the cutting structure from the bottom of the cutting main roller 11 below 1.

The two sets of tension mechanisms 2 are respectively located on both sides of the cutting mechanism 1 and can be arranged symmetrically. The tension wheel 21 is located below the tension driver 22 , and the tension driver 22 drives the tension wheel 21 to swing in the left and right direction of FIG. 9 to adjust the tension of the cutting wire 7 . The top end of the tension wheel 21 is lower than the bottom of the main cutting roller 11 below, so that the cutting lines wound out from the main cutting roller 11 to both sides are wound obliquely downward on the tension wheel 21 .

As shown in the view angle of Figure 9, both sets of retracting and unwinding mechanisms 3 are located on the left side of the tension mechanism 2. The two sets of wire retracting and releasing mechanisms 3 can be at the same height or at different heights. As shown in FIG. 9 , the wire retracting and unwinding mechanism 3 provided on the same side as the tension mechanism 2 is higher than the other wire retracting and unwinding mechanism 3 , and both groups of wire retracting and unwinding mechanisms 3 are lower than the tension wheel 21 .

The above solution makes the wire wheel structure more compact and saves space. In addition, the cutting line extends directly from the bottom of the main cutting roller to the tension mechanism, which can prevent the cutting line from passing through the cutting chamber door. In this solution, an opening can be made in the cutting frame for the cutting line to pass through. It is easier and more convenient to waterproof the opening of the cutting frame.

Regarding the positional relationship between the take-up and pay-off roller 31 and the take-up and pay-off rotation driver 32 in the take-up and pay-off mechanism 3, various methods can be adopted, for example: as shown in Figure 10, when the two sets of take-up and pay-off mechanisms 3 are at the same height When cutting, along the axis direction of the main cutting roller 11, the retracting and unwinding wire rotation driver 32 is in the middle, and the retracting and unwinding wire rollers 31 are at both ends; or the retracting and unwinding wire rotating drivers 32 can be at both ends, and the retracting and unwinding wire rollers 31 are in the middle. . As shown in Figure 11, when the two sets of retracting and unwinding mechanisms 3 are at different heights, they can be arranged staggered or arranged up and down. For example, along the axis direction of the main cutting roller 11, the two sets of retracting and unwinding mechanisms 3 The take-up and pay-off line rotation driver 32 is in the middle, and the take-up and pay-off line rollers 31 are at both ends.

Taking the solution shown in Figure 9 as an example, one winding direction is: after the cutting line 7 is wound out from the upper retracting and unwinding roller 31, it goes around the tension wheel 21 from the left, then extends to the upper right, and cuts the main roller from below. The bottom of 11 is wound into the cutting mechanism, and is wound around the three main cutting rollers 11 in the counterclockwise direction. Then, the bottom of the main cutting roller 11 is wound out of the cutting mechanism, and extended to the lower right to wind around the tension wheel 21 on the right. It is stored in the take-up and pay-off line roller 31 on the lower left side. During the operation of the slicer, the cutting line moves back and forth along the same path, That is: the forward movement is the same as the above-mentioned winding direction, and the reverse movement is opposite to the above-mentioned winding direction.

The above-mentioned solution of placing two sets of retracting and unwinding mechanisms 3 on the same side of the cutting mechanism facilitates the unified arrangement of the retracting and unwinding mechanisms 3, and the space on the other side of the cutting mechanism 3 can be used to place other equipment of the slicer, such as: electronic control equipment, Lubrication equipment, cooling equipment, etc. can improve space utilization.

Example 2

Figure 12 is a second layout schematic diagram of a wire saw unit provided by an embodiment of the present application. As shown in Figure 12, the only difference between Example 2 and Example 1 is that the cutting mechanism 1 is different, and the structure and layout of the tension mechanism 2 and the retracting and unwinding mechanism 3 are the same as Example 1.

Specifically, the cutting mechanism 1 includes: two horizontally arranged main cutting rollers 11 , and the cutting line 7 winds into or out of the top or bottom of the main cutting rollers 11 . The solution shown in FIG. 12 is that the cutting line 7 winds into or out of the main cutting roller 11 from the bottom of the main cutting roller 11 .

Taking the solution shown in Figure 12 as an example, one winding direction is: after the cutting line 7 is wound out from the upper retracting and unwinding roller 31, it goes around the tension wheel 21 from the left, then extends to the upper right, and cuts the main roller from the right. The bottom of 11 is wound into the cutting mechanism, and is wound around the two main cutting rollers 11 in the counterclockwise direction. Then, the cutting mechanism is wound out from the bottom of the main cutting roller 11 on the left, and extended to the lower right to wind around the tension wheel 21 on the right. It is stored in the take-up and pay-off line roller 31 on the lower left side. During the operation of the slicer, the cutting wire moves back and forth along the same path, that is, the forward movement is the same as the above-mentioned winding direction, and the reverse movement is opposite to the above-mentioned winding direction.

The solution provided in this example is to place the two sets of retracting and unwinding mechanisms 3 on the same side of the cutting mechanism, which facilitates the unified arrangement of the retracting and unwinding mechanisms 3, and the space on the other side of the cutting mechanism 3 can be used to place other equipment of the slicer. For example: electronic control equipment, lubrication equipment, cooling equipment, etc., which can improve space utilization.

Example three

This example provides a solution in which two sets of wire retracting and unwinding mechanisms 3 and two sets of tension mechanisms 2 are located on the same side of the cutting mechanism.

Figure 13 is a third layout schematic diagram of a wire saw unit provided by an embodiment of the present application. As shown in Figure 13, the cutting mechanism 1 includes at least three main cutting rollers 11, of which two main cutting rollers 11 are on the upper side and at least one main cutting roller 11 is on the lower side. Figure 13 shows two main cutting rollers 11 on top and one main cutting roller 11 on the bottom forming a triangle. The silicon rod moves downward from above, and the cutting line between the two upper cutting main rollers 11 cuts the silicon rod.

In Figure 13, the cutting line 7 winds in or out from the top of the upper cutting main roller 11 and the bottom of the lower cutting main roller 11 respectively. Judging from the moving direction of the cutting line, the cutting line 7 goes around the cutting structure 1 from the bottom of the main cutting roller 11 below, and goes out of the cutting structure 1 from the top of the main cutting roller 11 on the upper left side; when the cutting line moves in the opposite direction, The cutting line 7 winds into the cutting structure 1 from the top of the main cutting roller 11 on the upper left side, and winds out of the cutting structure 1 from the bottom of the main cutting roller 11 below.

Two sets of tension mechanisms 2 are located on the same side of the cutting mechanism 1, and a set of tension mechanisms 2 and a set of retracting and unwinding mechanisms 3 constitute a set of wire wheel sets. The heights of the two wire wheel groups are different. In the upper wire wheel group, the tension wheel 21 is higher than the take-up and pay-off roller 31 . In the lower wire wheel group, the tension wheel 21 is lower than the wire take-up and pay-off roller 31 .

As shown in the view angle of Figure 13, both sets of retracting and unwinding mechanisms 3 are located on the left side of the tension mechanism 2. The two sets of wire retracting and releasing mechanisms 3 can be at the same height or at different heights. As shown in FIG. 13 , the wire retracting and unwinding mechanism 3 provided on the same side as the tension mechanism 2 is higher than the other wire retracting and unwinding mechanism 3 , and both groups of wire retracting and unwinding mechanisms 3 are lower than the tension wheel 21 .

As for the take-up and pay-off roller 31 in the take-up and pay-off mechanism 3, the axis of the take-up and pay-off roller 31 and the axis of the cutting main roller 11 are straight lines in different planes.

Taking the solution shown in Figure 13 as an example, one winding direction is: after the cutting line 7 is wound out from the upper retracting and unwinding roller 31, it goes diagonally upward around the tension wheel 21, and then extends diagonally downward to cut the main roller 11 from below. The bottom of the cutting mechanism is wound into the cutting mechanism, and is wound around the three main cutting rollers 11 in a counterclockwise direction. Then, the cutting mechanism is wound out from the top of the main cutting roller 11 on the left side above, and extended to the lower left around the tension wheel 21 located below, and then Stored in the corresponding take-up and pay-off roller 31. During the operation of the slicer, the cutting wire moves back and forth along the same path, that is, the forward movement is the same as the above-mentioned winding direction, and the reverse movement is opposite to the above-mentioned winding direction.

The above-mentioned solution of placing two sets of wire retracting and unwinding mechanisms 3 and two sets of tension mechanisms 2 on the same side of the cutting mechanism facilitates unified wiring. The space on the other side of the cutting mechanism 3 can be used to place other equipment of the slicer, such as electronic control equipment, lubrication equipment, cooling equipment, etc., which can improve space utilization.

The following examples show the solution in which two sets of wire retracting and unwinding mechanisms 3 are respectively located on both sides of the cutting mechanism 1, and two sets of tension mechanisms 2 are respectively located on both sides of the cutting mechanism 1.

In Example 1 and Example 2, the take-up and pay-off roller 31 is lower than the tension wheel 21 . The difference between the following Examples 4, 5 and 6 is that: the retracting and unwinding roller 31 is higher than the tension wheel 21 on the same side, the cutting wire winds in or out from both sides of the cutting mechanism 1, and the cutting wire wound out from the cutting mechanism 1 The wire bypasses the tension wheel 21 downward and is stored upward on the retracting and unwinding roller 31 . The cutting wire wound out from the retracting and unwinding roller 31 bypasses the tension wheel 21 and then enters the cutting mechanism 1 .

Example 4

Figure 14 is a fourth layout schematic diagram of a wire saw unit provided by an embodiment of the present application. As shown in FIG. 14 , the cutting mechanism 1 includes two horizontally arranged main cutting rollers 11 , and the cutting line 7 winds in or out from the top or bottom of the main cutting rollers 11 . The solution shown in Figure 14 is that the cutting line 7 is wound in or out from the bottom of the main cutting roller 11. The silicon rod moves from top to bottom, and the cutting line between the tops of the two cutting main rollers 11 cuts the silicon rod.

Judging from the moving direction of the cutting line, the cutting line 7 goes around the cutting structure 1 from the bottom of the right cutting main roller 11, and goes out of the cutting structure 1 from the bottom of the left cutting main roller 11; when the cutting line moves in the opposite direction, the cutting line 7 The wire 7 winds into the cutting structure 1 from the bottom of the left cutting main roller 11 and winds out of the cutting structure 1 from the bottom of the right cutting main roller 11 .

The two sets of tension mechanisms 2 are respectively located on both sides of the cutting mechanism 1 and can be arranged symmetrically. The tension wheel 21 is located above the tension driver 22 , and the tension driver 22 drives the tension wheel 21 to swing to adjust the tension of the cutting wire 7 . The axis of the tension wheel 21 is parallel to the axis of the main cutting roller 11 .

As shown in the view angle of Figure 14, two sets of wire retracting and unwinding mechanisms 3 are respectively located on both sides of the cutting mechanism 1 and can be arranged symmetrically. The tension wheel 21 may be located outside the wire take-up and pay-off roller 31 , or may be located inside the wire take-up and pay-off roller 31 . When the tension wheel 21 is located outside the wire take-up and pay-off roller 31, the cutting wire passes through the tension wheel 21 and is stored inward on the wire take-up and pay-off roller 31. The distance between the two sets of retracting and unwinding mechanisms 3 and the cutting frame is relatively close, which can reduce the size of the slicer. The axis of the take-up and unwind roller 31 is parallel to the axis of the main cutting roller 11 .

Taking the solution shown in Figure 14 as an example, one winding direction is: after the cutting line 7 is wound out from the retracting and unwinding roller 31 on the left, it goes around the tension wheel 21 from the left, then extends to the upper right, and cuts the main thread from the right. The bottom of the roller 11 is wound into the cutting mechanism, and is wound around the two main cutting rollers 11 in the counterclockwise direction. Then, the bottom of the main cutting roller 11 on the left is wound out of the cutting mechanism, and extended to the lower right to wind around the tension wheel 21 on the right. Then it is stored in the take-up and pay-off line roller 31 on the right side. During the operation of the slicer, the cutting wire moves back and forth along the same path, that is, the forward movement is the same as the above-mentioned winding direction, and the reverse movement is opposite to the above-mentioned winding direction.

Based on the above technical solution, the cutting mechanism 1 can also use three cutting main rollers 11 to form a triangle, and the cutting line winds into or out of the cutting mechanism 1 from the bottom of the cutting main rollers 11 below. The arrangement of the three main cutting rollers 11 can refer to Example 1.

In the solution provided in this example, the positions of the tension mechanism and the retracting and unwinding mechanism can be flexibly adjusted to adapt to the structural layout of the slicer. Moreover, the cutting line is routed from the bottom of the main cutting roller to avoid opening the threading on the cutting chamber door. The implementation process is simpler and does not affect the opening and closing of the cutting chamber door.

Example five

Figure 15 is a fifth layout schematic diagram of a wire saw unit provided by an embodiment of the present application. As shown in Figure 15, what is different from Example 4 is that in Example 5, the cutting wire winds into or out of the cutting mechanism 1 from the top, and the position of the wire retracting and unwinding roller 31 changes slightly.

Specifically, as shown in FIG. 15 , the cutting mechanism 1 includes two horizontally arranged main cutting rollers 11 , and the cutting line 7 winds in or out from the top of the main cutting rollers 11 . The silicon rod moves from top to bottom, and the cutting line between the tops of the two cutting main rollers 11 cuts the silicon rod.

Example 8

The only difference between this example and Example 7 is that the cutting mechanism 1 is different, while the structure and layout of the tension mechanism 2 and the retracting and unwinding mechanism 3 are the same as Example 7.

FIG. 19 is a schematic diagram of the eighth layout of the wire saw unit provided by the embodiment of the present application. FIG. 20 is a schematic top view of the eighth layout of the wire saw unit provided by the embodiment of the present application. As shown in Figures 19 and 20, specifically, the cutting mechanism 1 includes three main cutting rollers 11 forming a triangle, with two main cutting rollers 11 on top and one main cutting roller 11 on the bottom. The cutting line winds into or out of the cutting mechanism 1 from the tops of the upper two main cutting rollers 11 . The cutting line between the two upper cutting main rollers 11 is used to cut the silicon rod moving from top to bottom.

Taking the solution shown in Figure 19 as an example, one winding direction is: after the cutting line 7 is wound out from the retracting and unwinding roller 31 on the left, it is inclined to the lower left around the tension wheel 21, and then extends to the upper right, from the upper left The top of the cutting main roller 11 is wound into the cutting mechanism, and is wound around the three cutting main rollers 11 in a clockwise direction.

FIG. 21 is a schematic diagram of the ninth layout of the wire saw unit provided by the embodiment of the present application. FIG. 22 is a schematic top view of the ninth layout of the wire saw unit provided by the embodiment of the present application. As shown in Figures 21 and 22, the cutting mechanism 1 includes three main cutting rollers 11 forming a triangle, with two main cutting rollers 11 at the top and one main cutting roller 11 at the bottom. The cutting line winds into and out of the cutting mechanism 1 from the bottom of the lower cutting main roller 11 . The cutting line between the two upper cutting main rollers 11 is used to cut the silicon rod moving from top to bottom.

From the perspective of the moving direction of the cutting line, the cutting line 7 goes around the cutting structure 1 from the bottom of the main cutting roller 11 below, and goes out of the cutting structure 1 from the bottom of the main cutting roller 11 below; when the cutting line moves in the opposite direction, the cutting line 7 The wire 7 winds into the cutting structure 1 from the bottom of the lower cutting main roller 11 and winds out of the cutting structure 1 from the bottom of the lower cutting main roller 11 .

During the operation of the slicer, the cutting wire moves back and forth along the same path, that is, the forward movement is the same as the above-mentioned winding direction, and the reverse movement is opposite to the above-mentioned winding direction.

In this example, the retracting and unwinding rollers and the tension wheel are placed at the same height, making the wire saw unit structure more compact and the distance between the mechanisms closer, shortening the winding length of the cutting wire, and ensuring that the tension of the cutting wire meets the cutting requirements. In addition, the cutting frame space under the wire saw unit can be used to place other components, such as electronic control equipment, cooling equipment, lubrication equipment, etc., to improve space utilization.

Example 15

The only difference between Example 15 and Example 14 is that the cutting mechanism 1 is different, and the structure and layout of the wire retracting and unwinding mechanism 3 are the same as Example 14.

As shown in Figure 30, the cutting mechanism 1 includes three main cutting rollers 11 forming a triangle, with two main cutting rollers 11 on top and one main cutting roller 11 on the bottom. The cutting line winds into or out of the cutting mechanism 1 from the bottom of the lower cutting main roller 11 . The cutting line between the two upper cutting main rollers 11 is used to cut the silicon rod moving from top to bottom.
