Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to a line correction device. Background Technology

[0002] Polycrystalline silicon needs to be cut during production. Existing silicon core cutting machines often use diamond wire to cut polycrystalline silicon. Existing silicon core cutting machines include a take-up and undo device, which includes a take-up and undo plate. The take-up and undo plate is equipped with two wire laying devices for taking up and undoing the wire. When one of the two wire laying devices is used as a take-up device, the other is used as a undoing device. Each wire laying device includes a winding roller and a winding drive motor that drives the winding roller to rotate. The cutting wire on the winding roller is transferred to the transition wheel position of the cutting head via a guide wheel.

[0003] Diamond wire is generally quite hard, so it is necessary to ensure that the diamond wire is perpendicular and tangent to the guide wheel when it exits the winding roller. Otherwise, it will cause great wear to the guide wheel and have a short service life. Utility Model Content

[0004] In order to solve the technical problem that diamond wire easily causes wear to the guide wheel when exiting the winding roller in the prior art, this utility model provides a wire correction device, which solves the above-mentioned technical problem.

[0005] To solve the above-mentioned technical problems, this utility model provides a line correction device, comprising:

[0006] A correction wheel, which is configured for the winding roller;

[0007] A cantilever arm, wherein the steering wheel is deflected and mounted via the cantilever arm, and the hinge axis of the cantilever arm is tangent to the steering wheel;

[0008] A correction assembly is mounted on the cantilever, and the line between the correction wheel and the winding roller passes through the correction assembly.

[0009] According to one embodiment of the present invention, the hinge axis of the cantilever is parallel to the axis of the winding roller, and the axis of the straightening wheel is perpendicular to the axis of the winding roller.

[0010] According to one embodiment of the present invention, the axis of the winding roller extends vertically, and the axis of the straightening wheel extends horizontally.

[0011] According to one embodiment of the present invention, the correction assembly includes a correction seat and two rotating drums. The two rotating drums are located on the correction seat along a direction parallel to the axis of the winding roller, and there is a gap between the two rotating drums, through which the wire passes.

[0012] According to one embodiment of the present invention, a sensor is provided at the rotating drum.

[0013] According to one embodiment of the present invention, the gap is at the same height as the highest point of the correction wheel.

[0014] According to one embodiment of the present invention, the axial position of the winding roller is adjustable so that the line between the winding roller and the straightening wheel extends horizontally.

[0015] According to one embodiment of the present invention, it further includes a guide wheel assembly, the guide wheel assembly further includes a first guide wheel, the correction wheel is located between the first guide wheel and the winding roller, and the first guide wheel is tangent to the hinge axis of the cantilever.

[0016] According to one embodiment of the present invention, it further includes a second guide wheel and a third guide wheel, wherein the first guide wheel, the second guide wheel and the third guide wheel are on the same plane.

[0017] According to one embodiment of the present invention, a tensioning wheel is further included. The tensioning wheel is mounted on one end of the tensioning rod, the middle part of the tensioning rod is rotatably mounted, and a counterweight is mounted on the other end of the tensioning rod. The tensioning rod rotates under the drive of the tensioning drive device.

[0018] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0019] 1. The thread correction device of this utility model includes a correction wheel, a cantilever, and a correction assembly. The cantilever is hinged, and both the correction wheel and the correction assembly are mounted on the cantilever. Because the cantilever is hinged, when the winding roller is taking in or releasing the thread, the thread on the winding roller winds from the inside out and from one end to the other axially. During take-in and release, the radial and axial positions of the thread entry and exit points on the winding roller change. Therefore, the yaw setting of the correction wheel can adaptively change the radial position of the take-in and release points, ensuring that the thread always passes directly through the correction wheel without being affected by the change in the radial position of the thread entry and exit points. There is an angle between them, which causes wear on the straightening wheel; the straightening component can work with the drive device to detect and correct the changes in the axial position of the take-up and undo points on the winding roller. The straightening component swings with the cantilever to adapt to the changes in the radial position of the take-up and undo points, so that the line between the straightening wheel and the winding roller always passes through the straightening component and will not detach from the straightening component due to changes in the radial position. Therefore, the line straightening device in this embodiment can realize adaptive adjustment of the radial and axial positions of the take-up and undo points on the winding roller, ensuring that the line passes smoothly between the winding roller and the straightening wheel.

[0020] 2. In the wire correction device of this utility model, the axis of the winding roller is perpendicular to the axis of the correction wheel, so the winding roller and the correction wheel can be arranged more compactly, saving space.

[0021] 3. In the wire correction device of this utility model, the wire passes through two rotating drums of the correction device. Sensors are installed at the two rotating drums. When the wire produces an axial position deviation, the sensor can detect the axial position deviation and trigger the drive device to adjust the axial position of the winding roller to ensure that the wire extends horizontally between the correction wheel and the winding roller.

[0022] 4. In the line correction device of this utility model, the first guide wheel is tangent to the hinge axis of the cantilever, and the correction wheel is tangent to the hinge axis of the cantilever. Therefore, the line between the correction wheel and the first guide wheel extends vertically, which can avoid wear on the correction wheel and the first guide wheel. Attached Figure Description

[0034] like Figure 1-4 As shown, this embodiment provides a line correction device, including a correction wheel 1, a cantilever 3, and a correction assembly 4. Both the correction wheel 1 and the correction assembly 4 are mounted on the cantilever 3. The correction wheel 1, cantilever 3, and correction assembly 4 are configured for a winding roller 2. Since the axial and radial positions of the take-up and undo points of the line on the winding roller 2 change during take-up and undoing, the line correction device formed by the correction wheel 1, cantilever 3, and correction assembly 4 can adaptively adapt to the changes in the positions of the incoming and outgoing lines on the winding roller 2. When the winding roller 2 is a take-up roller, the line 5 can be wound onto the winding roller 2 in a straight and tangential state. When the winding roller 2 is an undoing roller, the line undoing from the winding roller 2 can pass through the correction wheel 1 in a straight and tangential manner. The take-up and undo points are the points of tangency between the line 5 and the winding roller 2 during take-up and undoing.

[0035] The straightening wheel 1 is deflected and assembled via the cantilever 3. The straightening wheel 1 is mounted on one end of the cantilever 3, and the other end of the cantilever 3 is hinged. The hinge axis of the cantilever 3 is tangent to the straightening wheel 1. Thus, when the straightening wheel 1 is used to guide the winding roller 2, the side of the straightening wheel 1 closest to the winding roller 2 can deflect along the hinge axis of the cantilever 3, while the other side of the straightening wheel 1 is tangent to the hinge axis of the cantilever 3, and its tangential position remains unchanged.

[0036] To save space, the axis of the winding roller 2 is perpendicular to the axis of the straightening wheel 1. Specifically, the axis of the winding roller 2 extends vertically, while the straightening wheel 1 extends horizontally. The winding roller 2 can be either a take-up roller or a release roller. Driven by a rotary drive device, the winding roller 2 rotates to take up or release the wire. The winding roller 2 can also move axially under the drive device to ensure that the wire passes horizontally between the winding roller 2 and the straightening wheel 1. Specifically, the winding roller 2 and the rotary drive device can be mounted on the same mounting base. The drive device raises and lowers the mounting base and the winding roller 2 and rotary drive device on it.

[0037] The cantilever 3 can be configured in various shapes. In this embodiment, the cantilever 3 is an inverted L-shape. The lower end of the cantilever 3 is connected to the correction wheel 1, and the upper end of the cantilever 3 is hinged. The hinge axis of the cantilever 3 extends vertically and is tangent to the correction wheel 1.

[0038] The correction component 4 is mounted on the cantilever 3. The correction component 4 includes a correction seat 41 and two rotating cylinders 42. The two rotating cylinders 42 are arranged vertically on the correction seat 41, and there is a gap 43 between the two rotating cylinders 42 so that the line 5 can pass through.

[0039] As a preferred technical solution in this embodiment, the gap 43 between the two rotating drums 42 is on the same horizontal line as the highest point of the correction wheel 1, and the line between the winding roller 2 and the correction wheel 1 passes through the gap 43 of the correction component 4.

[0040] As a preferred technical solution in this embodiment, a sensor is provided on the rotating drum 42. Under normal operating conditions, the entry and exit points of the winding roller 2, the gap 43, and the highest point of the straightening wheel 1 are located on the same horizontal line, and the wire 5 extends horizontally between the winding roller 2 and the straightening wheel 1. If the winding roller 2 is too high, the wire 5 will exert a force on the rotating drum 42 above. After the sensor detects this force, it can trigger the drive device to drive the winding roller 2 to lower its height appropriately. If the winding roller 2 is too low, the wire 5 will exert a force on the rotating drum 43 below. After the sensor detects this force, it can trigger the drive device to drive the winding roller 2 to raise its height appropriately.

[0041] The guide wheel assembly 6 includes a first guide wheel 61, a second guide wheel 62, and a third guide wheel 63. The number of guide wheels can be set according to actual needs.

[0042] As a preferred embodiment, the first guide wheel 61, the second guide wheel 62, and the third guide wheel 63 are all mounted on the mounting plate 7. Preferably, the mounting plate 7 is vertically arranged, and the axes of the first guide wheel 61, the second guide wheel 62, and the third guide wheel 63 all extend horizontally.

[0043] As a preferred embodiment, the first guide wheel 61, the second guide wheel 62, and the third guide wheel 63 are located on the same vertical plane. The straightening wheel 1 can be tilted relative to this vertical plane to adapt to the position of the incoming and outgoing wires on the winding roller 2. The first guide wheel 61, the second guide wheel 62, and the third guide wheel 63 are located below the straightening wheel 1. The first guide wheel 61 is tangent to the hinge axis of the cantilever 3. When the winding roller 2 is a feed roller, the feed wire 5 can extend vertically through the first guide wheel 61 after passing through the straightening wheel 1. The second guide wheel 62 is located directly below the first guide wheel 61, and the third guide wheel 63 is located diagonally below the second guide wheel 62.

[0044] To ensure the tension of the line 5, a tensioning assembly 8 is also provided. The tensioning assembly 8 includes a tensioning wheel 81, which is mounted on one end of a tensioning rod 82. The tensioning rod 82 is hinged. The tensioning drive device 84 drives the tensioning rod 82 to rotate, which in turn causes the tensioning wheel 81 to swing, thereby adjusting the tension of the line 5.

[0045] As a preferred technical solution in this embodiment, the middle part of the tensioning rod 82 is hinged and assembled through a hinge shaft. The hinge shaft of the tensioning rod 82 is perpendicular to the tensioning rod 82. The other end of the tensioning rod 82 away from the tensioning wheel 81 is equipped with a counterweight 84 to ensure the balance of the tensioning wheel 81 during operation.

[0046] As a preferred embodiment, the tensioning pulley 81 is located between the first guide pulley 61 and the first guide pulley 62. Preferably, the tensioning pulley 81, the first guide pulley 61, the first guide pulley 62, and the third guide pulley 63 are located on the same plane; the highest point of the tensioning pulley 81 and the lowest point of the first guide pulley 61 are at the same height, and the line 5 between the first guide pulley 61 and the tensioning pulley 81 extends horizontally; the lowest point of the tensioning pulley 81 and the highest point of the first guide pulley 62 are at the same height, and the line 5 between the tensioning pulley 81 and the first guide pulley 62 extends horizontally.

[0047] Line 5 is a cutting line. In this embodiment, line 5 can be selected from, but is not limited to, diamond wire.

[0048] Based on its structure, the line correction device of this embodiment can achieve the following when the winding roller 2 is winding and unwinding: the line 5 between the winding roller 2 and the correction wheel 1 extends horizontally, and the line 5 between the winding roller 2 and the correction wheel 1 is coplanar with the plane where the correction wheel 1 is located, without any included angle; the line 5 between the correction wheel 1 and the first guide wheel 61 extends vertically, and the line 5 between the first guide wheel 61 and the tension wheel 81, and the line 5 between the tension wheel 81 and the first guide wheel 62, all extend horizontally, so that the line 5 passes between each guide wheel and the tension wheel 81 as straight as possible, reducing the wear of the line 5 on the guide wheel and the tension wheel 81, and extending the service life.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments.
