Description

Technical Field

[0001] The invention relates to the technical field of silicon rods, and in particular to a ring wire squaring cutting mechanism. Background Art

[0002] Currently, most of the silicon rods are squared and cut by a ring wire squaring mechanism. The cutting principle is as follows: a ring wire is wound around the driving wheel and the driven wheel in the ring wire squaring mechanism, and the driving wheel and the driven wheel drive the steel wire to rotate. The ring wire squaring mechanism drives the driving wheel and the driven wheel to move downward in the radial direction, and the ring wire wound around the driving wheel and the driven wheel moves downward. The steel wire moves downward along the axial direction of the cylindrical silicon rod to cut the circumferential side wall of the silicon rod to form a rectangular silicon rod. However, the ring wire on the ring wire squaring mechanism of this setting can only cut one side of the silicon rod at a time. It is necessary to change the position of the silicon rod four times and repeatedly move up and down to change the wire and square the mechanism to complete the cutting of the four sides of the silicon rod. The cutting efficiency is low. Summary of the invention

[0059] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 1 The orientation is taken as a reference, and the “front” refers to the staff facing Figure 1 The direction is referenced.

[0060] See also Figure 1-Figure 5 The loop wire squaring cutting mechanism proposed in the embodiment of the present invention includes a cutting bracket 1, a driving wheel 2, a driven wheel 3 and a loop wire 4.

[0061] The driving wheel 2 is rotatably disposed at the first end of the bottom of the cutting bracket 1, and the axis of the driving wheel 2 is vertically disposed. The driven wheel 3 is rotatably disposed at the second end of the bottom of the cutting bracket 1, and the axis of the driven wheel 3 is vertically disposed. The loop wire 4 is wound around the driving wheel 2 and the driven wheel 3, and the driving wheel 2 is used to drive the driven wheel 3 and the loop wire 4 to rotate. When the loop wire 4 rotates, the two opposite cutting sections of the loop wire 4 can cut the opposite sides of the silicon rod 8 at the same time. It should be noted that the vertical in the above context includes parallel to the feeding direction, and inclined to the feeding direction (such as Figure 1 ) two situations.

[0062] The driving wheel 2 is rotatably set at the first end of the bottom of the cutting bracket 1, and the driven wheel 3 is rotatably set at the second end of the bottom of the cutting bracket 1, and the axes of the driving wheel 2 and the driven wheel 3 are both set vertically. The loop wire 4 is wound around the driving wheel 2 and the driven wheel 3, and the driving wheel 3 drives the driven wheel 2 and the loop wire 4 to rotate. Therefore, when the cutting bracket 1 of the loop wire square cutting mechanism drives the driving wheel 2 and the driven wheel 3 to move downward and feed, the front and rear sections of the loop wire 4 correspond to the opposite sides of the silicon rod 8 respectively, so that the two opposite sides of the silicon rod 8 are cut out by one loop wire 4 at the same time, and the angle of the silicon rod 8 is adjusted once, and the other two opposite sides of the silicon rod 8 can be cut out, thereby greatly improving the square cutting efficiency of the silicon rod 8. At the same time, using one loop wire 4 to cut the two opposite sides of the silicon rod at the same time can ensure that the tension, wire bow and cutting speed of the loop wire 4 used to cut the two opposite sides of the silicon rod 8 are consistent, thereby improving the cutting accuracy and cutting quality of the silicon rod 8. At the same time, cutting the silicon rod 8 by one loop wire 4 can also facilitate the maintenance and replacement of the loop wire 4.

[0063] Furthermore, the loop wire squaring and cutting mechanism further comprises a tension adjusting assembly 7, which is used to adjust the tension of the loop wire 4. The tension adjusting assembly 7 comprises a tension adjusting motor 71, a tension adjusting lead screw 72 and a driving wheel support plate 73.

[0064] The tension adjustment motor 71 is fixedly connected to the bottom of the cutting bracket 1. The tension adjustment screw 72 is fixedly connected to the output end of the tension adjustment motor 71, and the tension adjustment screw 72 is oriented left and right. The driving wheel support plate 73 is threadedly connected to the tension adjustment screw 72. The driving wheel 2 is rotatably connected to the driving wheel support plate 73.

[0065] When in use, the tension adjustment motor 71 drives the tension adjustment screw 72 to rotate, and the tension adjustment screw 72 drives the driving wheel support plate 73 and the driving wheel 2 to move in the left and right directions to adjust the left and right distance between the driving wheel 2 and the driven wheel 3, and then adjust the tension of the loop line 4 wound around the driving wheel 2 and the driven wheel 3.

[0066] Furthermore, the tension adjustment assembly 7 also includes a driving wheel slide rail 74 .

[0067] The driving wheel rail 74 is fixedly connected to the bottom of the cutting bracket 1, and the driving wheel rail 74 is oriented left and right. The driving wheel support plate 73 is slidably arranged on the driving wheel rail 74 to improve the stability of the driving wheel support plate 73 when it moves left and right.

[0068] Specifically, the loop wire squaring cutting mechanism further includes a driving wheel driving motor which is fixedly connected to the driving wheel support plate 73, and the output end of the driving wheel driving motor is fixedly connected to the tension driving wheel 2 for driving the driving wheel 2 to rotate.

[0069] Specifically, the driving wheel 2 is rotatably connected to the driving wheel support plate 73 through a bearing. The driven wheel 3 is rotatably connected to the cutting bracket 1 through a bearing.

[0070] Furthermore, the loop wire squaring cutting mechanism also includes a wheel unit 5 and a tension sensor.

[0071] The wheel unit 5 is rotatably arranged at the bottom of the cutting bracket 1 and is located between the driving wheel 2 and the driven wheel 3 . The loop line 4 is wound around the wheel unit 5 . The wheel unit 5 is used to guide the loop line 4 to move.

[0072] Specifically, the wheel unit 5 includes two wheel assemblies.

[0073] The two wheel assemblies are spaced apart on the left and right sides of the cutting bracket 1, and each wheel assembly includes two wheels 51. The two wheels 51 rotate and are spaced apart on the front and back sides of the cutting bracket 1. The axes of the wheels 51 are vertically arranged, and the loop line 4 is wound around the opposite side of the two wheels 51. The wheels 51 are used to guide the movement of the loop line 4.

[0074] Specifically, the wheel unit 5 further includes two crimping wheel assemblies.

[0075] Two crimping wheel assemblies are arranged at intervals on the left and right sides of the cutting bracket 1. Each crimping wheel assembly includes two crimping wheels 52. The two crimping wheels 52 rotate and are arranged at intervals on the front and rear sides of the cutting bracket 1. The axes of the crimping wheels 52 are arranged horizontally. The loop wire 4 is wound around the bottom of the crimping wheels 52. The crimping wheels 52 are used to guide the movement of the loop wire 4 and can support the loop wire 4 to prevent the loop wire 4 from being compressed and deformed and contacting the cutting bracket 1 when the loop wire 4 cuts the silicon rod 4.

[0076] Specifically, see Figure 1 The driving wheel 2, the passing wheel 51, the pressing wheel 52 and the following wheel 3 located on the same side in the front-rear direction of the cutting bracket 1 are configured as follows:

[0077] The loop wire 4 wound around the driving wheel 2 or the driven wheel 3, the passing wheel 51 and the pressing wheel 52 forms an inclined section 41, and the loop wire 4 between the two pressing wheels 52 forms a horizontal section 42. The inclined section 41 and the horizontal section 42 form a pressing angle (i.e., an included angle) to ensure that the wheel body unit 5 can all contact the loop wire 4.

[0078] In actual use, when the loop wire squaring cutting mechanism moves downward, the loop wire 4 wound around the driving wheel 2, the driven wheel 3 and the wheel unit 5 rotates, and the two opposite cutting segments of the loop wire 4 simultaneously cut the opposite front and rear sides of the silicon rod 8, thereby cutting out two opposite side surfaces of the silicon rod 8 at one time. The loop wire squaring cutting mechanism moves upward to return and rotate the silicon rod 8, and then the loop wire squaring cutting mechanism moves downward again, and simultaneously cuts the other two opposite front and rear side surfaces of the silicon rod 8.

[0079] Furthermore, two spacing adjustment components 6 are provided at intervals on the front and rear sides of the cutting support 1. The spacing adjustment components 6 are used to adjust the spacing between two opposite cutting sections of the loop wire 4 along the front-to-back direction to be suitable for cutting silicon rods 8 of different diameters.

[0080] Specifically, each spacing adjustment assembly 6 includes a spacing adjustment motor 61, a spacing adjustment lead screw 62 and a wheel assembly support plate. The spacing adjustment motor 61 is fixedly connected to the bottom of the cutting bracket 1. The spacing adjustment lead screw 62 is connected to the output end of the spacing adjustment motor 61, and the spacing adjustment lead screw 62 is oriented forward and backward. The wheel assembly support plate and the spacing adjustment lead screw 62 are threadedly connected. The wheel assembly 5 is rotatably connected to the wheel assembly support plate.

[0081] When in use, the spacing adjustment motor 61 drives the spacing adjustment screw 62 to rotate, and the spacing adjustment screw 62 drives the wheel assembly support plate and the wheel unit 5 to move forward and backward to adjust the spacing between the two front-to-back relative wire pressing wheels 52 and the two front-to-back relative passing wheels 51 in the wheel unit 5, and then adjust the spacing between the two relative cutting sections of the loop wire 4 along the front-to-back direction to be suitable for cutting silicon rods 8 of different diameters.

[0082] Specifically, a first nut 621 is disposed at the end of the pitch adjustment screw 62 , and a second nut 611 is disposed at the output end of the pitch adjustment motor 61 .

[0083] Each spacing adjustment assembly 6 further includes a synchronous belt 64. The synchronous belt 64 is sleeved and threadedly connected to the first nut 621 and the second nut 611. When in use, the spacing adjustment motor 61 drives the spacing adjustment lead screw 62 to rotate through the synchronous belt 64.

[0084] Specifically, each spacing adjustment assembly 6 also includes a wheel assembly slide rail 65 .

[0085] The wheel assembly slide rail 65 is fixedly connected to the bottom of the cutting bracket 1, and the wheel assembly slide rail 65 is oriented forward and backward. The wheel assembly support plate is slidably arranged on the wheel assembly slide rail 65 to improve the stability of the wheel assembly support plate when it moves forward and backward.

[0086] Specifically, the wheel assembly support plate includes a crimping wheel support plate 632 and a passing wheel support plate 631 .

[0087] The crimping wheel 52 is rotatably connected to the crimping wheel support plate 632 through a bearing, and the crimping wheel support plate 632 is threadedly connected to the spacing adjustment screw 62. The passing wheel 51 is rotatably connected to the passing wheel support plate 631 through a bearing, and the passing wheel support plate 631 is fixedly connected to the crimping wheel support plate 632.

[0088] When in use, the spacing adjustment screw 62 drives the crimping wheel support plate 632 and the crimping wheel 52 to move forward and backward, and the crimping wheel support plate 632 drives the passing wheel support plate 631 and the passing wheel 51 to move forward and backward synchronously.

[0089] Specifically, the wheel support plate 631 is slidably disposed on the wheel assembly slide rail 65 to improve the stability of the wheel support plate 631 when it moves in the front-rear direction. Of course, multiple wheel assembly slide rails 65 may also be provided, and the wire pressing wheel support plate 632 may also be slidably disposed on the wheel assembly slide rail 65 to further improve the stability of the wire pressing wheel support plate 632 when it moves in the front-rear direction.

[0090] Furthermore, the loop wire squaring and cutting mechanism further comprises a tension sensor which is arranged on the wheel unit 5 and is used to monitor the tension of the loop wire 4 .

[0091] In actual use, the tension of the loop wire 4 is monitored by the tension sensor, which can assist in adjusting the tension value of the loop wire 4 and determine whether the loop wire squaring cutting mechanism has completed one cutting. Its working principle is:

[0092] Before the loop wire squaring cutting mechanism cuts the silicon rod 8, the tension sensor can monitor the tension of the loop wire 4 in real time. When the spacing adjustment component 6 adjusts the spacing between the two relatively cut sections of the loop wire 4 in the front-to-back direction, the tension sensor and the tension adjustment component 7 cooperate to adjust the tension value of the loop wire 4 to keep it constant, so as to avoid the loop wire 4 being alternately loosened and tightened and falling off or breaking during the process of adjusting the spacing of the loop wire 4. At the same time, the tension sensor and the tension adjustment component 7 cooperate to adjust the tension value of the loop wire 4 to the set value and keep it constant, so as to improve the adjustment accuracy of the tension of the loop wire 4.

[0093] When the loop wire squaring cutting mechanism is in the process of cutting the silicon rod 8, the tension sensor monitors the tension of the loop wire 4 in real time, and adjusts the downward feed speed of the loop wire squaring cutting mechanism and / or the rotation speed of the driving wheel driving motor to adjust the rotation speed of the loop wire 4 wound around the driving wheel 2 and the driven wheel 3, so that the tension of the loop wire 4 is always stable within the set range, so as to improve the cutting accuracy of the silicon rod 8.

[0094] When the loop wire squaring cutting mechanism completes cutting the silicon rod 8, the tension sensor monitors in real time that the tension on the loop wire 4 decreases sharply, thereby judging that the silicon rod 8 is cut completely, and the loop wire squaring cutting mechanism can stop moving downward in time to improve cutting efficiency.

[0095] Specifically, the tension sensor is arranged on the passing wheel 51 or the pressing wheel 52 in the wheel unit 5. Of course, a plurality of tension sensors may also be arranged, and are arranged on the passing wheel 51 or the pressing wheel 52 respectively, to improve the monitoring accuracy of the loop line 4.

[0096] For better explanation, the working principle of the circular wire squaring cutting mechanism is as follows:

[0097] S1, the margin adjustment mechanism 6 adjusts the distance between two opposite cutting sections of the loop line 4 along the front-to-back direction to be suitable for cutting silicon rods 8 of different diameters;

[0098] S2, the tension adjustment component 7 adjusts the left-right distance between the driving wheel 2 and the driven wheel 3 to adjust the tension of the loop line 4 wound around the driving wheel 2 and the driven wheel 3 so that the loop line 4 reaches the initial tension value;

[0099] S3, the driving wheel 2 rotates and drives the driven wheel 3 and the loop 4 to rotate synchronously;

[0100] S4, the loop line squaring cutting mechanism moves downward and drives the two opposite cutting sections of the loop line 4 to cut the front and rear sides of the silicon rod 8 at the same time;

[0101] S5, the tension sensor monitors the tension value of the loop wire 4 in real time, and adjusts the downward feed speed of the loop wire squaring cutting mechanism and / or adjusts the speed of the driving wheel driving motor to adjust the speed of the loop wire 4, so as to ensure that the tension value of the loop wire 4 when cutting the silicon rod 8 remains constant, so as to improve the cutting accuracy and cutting quality of the silicon rod 8;

[0102] S6. When the loop wire squaring cutting mechanism has completed cutting the two opposite sides of the silicon rod 4, the tension sensor monitors in real time that the tension value of the loop wire 4 has dropped sharply, and the loop wire squaring cutting mechanism stops moving down to feed and cut, so as to improve the cutting efficiency.

[0103] Furthermore, the loop wire squaring cutting mechanism also includes a controller, which is communicatively connected with a tension sensor, a speed regulating mechanism for adjusting the downward feed speed of the cutting bracket 1, a driving wheel driving motor, a spacing adjusting motor 61 and a tension adjusting motor 71.

[0104] The tension sensor sends the tension value data of the loop wire 4 to the controller in real time. The controller is used to control the speed regulating mechanism to adjust the downward feeding speed of the cutting bracket 1, control the active wheel driving motor to adjust the rotation speed of the active wheel 2 to adjust the rotation speed of the loop wire 4, control the spacing adjustment motor 61 to adjust the spacing between the two relative cutting sections of the loop wire 4 along the front-to-back direction, and control the tension adjustment motor 71 to adjust the tension of the loop wire 4.

[0105] Therefore, the circular line squaring cutting mechanism can operate automatically, thereby improving the cutting efficiency and cutting accuracy.
