A driving wheel driving motor 518 is further disposed on the other side of the mounting plate 502, for driving the endless wire 505 to have a certain linear velocity.

The cutting wheel set and its ring wires may be arranged in different manners and the number of the cutting head assembly 50 shown in the drawings, wherein the cutting wheel set includes a driving wheel 503, two guiding wheels 504 and a tension wheel 506, but in other embodiments, the present utility model is not limited to the composition of the cutting wheels and the number of ring wires. During operation, the cutting head assembly 50 can move up and down on the feeding assembly 40 under the drive of the feeding motor 405 and can move horizontally on the upright assembly 30 transversely through the feeding assembly under the drive of the horizontal driving motor 404, and during processing, the annular wires 505 around the wheels are tensioned under the tensioning action of the tension wheels 506 and have a certain linear velocity under the drive of the driving wheel driving motor 518, so that the cutting capability is provided, and the cutting of the silicon rod can be realized by continuing to move downwards.

In addition, the cutting wheel set described above further includes a control system for the cutting wheel set according to any of the implementations of the embodiments below. As shown in connection with fig. 4, the control system may include a controller and a sensing element in communication with the controller, the sensing element may be disposed at a corresponding location on the mounting plate 502 of the cutting head assembly 50 and configured to sense the tension of the looped wire 505 of the cutting head assembly 50, and the controller may be configured to control the feed motor 405 of the feed assembly accordingly based on the tension and/or the trend of the tension as fed back by the sensing element.

The degree of tension can be obtained by detecting different physical quantities, for example, the detecting element can be a tension sensor or a moment sensor for detecting the tension of the loop wire, so that the controller can obtain the tension at a single time point or the tension at a plurality of time points from the detecting element, different tension can correspond to different degrees of tension, and the change trend of the tension can be obtained by a plurality of different tension. In addition, the detecting element may also be an angle sensor, different angles may correspond to different tensioning degrees, and the corresponding tensioning degrees may also be obtained through a certain angle detection, for example, as shown in the drawing, the tension wheel 506 of the cutting head assembly may be mounted on one side of the mounting plate 502 through the swing rod 507 and the rotating shaft 508, the detecting element may be an angle sensor, where the rotating shaft is connected to the angle sensor, and is used for detecting the rotating angle of the rotating shaft 508 or the swing rod 507; in particular embodiments, the sensing element may be disposed on the other side of the mounting plate 502.

In the process of cutting the annular wire 505, the detecting element is in communication with the controller, the controller can continuously obtain the tensioning condition of the annular wire (including the tensioning degree at a certain time point or the tensioning degree change trend at a certain time period) according to the feedback of the detecting element, if the tensioning is too large, for example, the annular wire 505 receives too large cutting resistance, the controller can control the action of the feeding motor 404 after the tensioning exceeds the preset degree, so that the feeding speed of the cutting head assembly 50 is slowed down, the tensioning degree of the annular wire can be correspondingly reduced, a new tensioning balance is formed, or when the tensioning change is too fast due to a specific factor, the feeding motor is adaptively controlled to adjust the feeding rhythm of the cutting head assembly 50, so that the tensioning degree of the annular wire 505 is stabilized and reaches the new balance, the influence of sudden conditions on the cutting head assembly and the cutting device can be effectively avoided or reduced, the cutting process is smoother, the service life of related components is prolonged, the cutting device is further adapted to more complex operation environment, and the quality control of the silicon rod is improved overall, and the processing precision is improved. In the specific implementation process, the controller can be built by adopting a PLC (Programmable Logic Controller, PLC, programmable logic controller) or a singlechip and the like, and is connected with controlled equipment (such as a feed motor 40) through an output interface, and each controlled motor can adopt a stepping motor, a servo motor or a variable frequency motor and the like.

On this basis, different structural schemes can be further adapted and the coverage range of the control system can be expanded, for example, as shown in fig. 3 and 4, the cutting head assembly 50 can further comprise a tension arm 515 and a balancing weight 517, the tension arm 515 is fixed with the rotating shaft 508 at the other side of the mounting plate 502, and the tensioning end of the tension arm 515 is rotatably connected with the balancing weight 517; the control system further includes a sensing plate 516 and a proximity switch 514 in communication with the controller, the sensing plate 516 being disposed at the free end of the tension arm 515, the proximity switch 514 being disposed on the other side of the mounting plate 502 and adjacent to a predetermined location of return travel of the free end of the tension arm 515. The controller is further configured to send corresponding indication information according to feedback of the proximity switch 514, for example, the cutting device may be externally connected with an alarm unit, in a working process, if the ring wire is broken, the cutting resistance disappears, under the action of the balancing weight 517, the rotating shaft 508 will rotate clockwise on the back of the mounting plate 502, so as to drive the tension arm 515 to rotate clockwise, and further, the free end (left end in the figure) of the tension arm 515 also rotates clockwise (i.e. rotates along the return stroke), when the tension arm 515 rotates to a predetermined position, the sensing plate 516 on the tension arm 515 enters a detection range of the proximity switch 514, and then the proximity switch sends response information to the controller, so that the controller can obtain a broken wire condition, and send indication information to the alarm unit, so that the alarm unit reminds a worker.

It will be appreciated by those skilled in the art that the weight 517 herein is a tension driver provided for a tension pulley. In the art, the tension driving member may be a realization form of a servo motor, an oil cylinder, an air cylinder, etc. which can provide torque, and the application is not limited.

In addition, in other implementations other than the one shown in fig. 3, the tensioning mechanism of the tension pulley 506 includes a tension motor and a speed reducer that are disposed on the other side of the mounting plate 502, and an output shaft of the tension motor is in transmission connection with the rotating shaft 508 through the speed reducer; the controller is also used for correspondingly controlling the tension motor according to the tension degree and/or the tension degree change trend fed back by the detection element. For example, during operation, such as when the tension is excessive or the tension is changed excessively due to a specific situation, the controller may adjust the driving of the tension motor accordingly, so that the tension degree is stabilized and a new balance is achieved. Such control of the tension motor may be performed separately from control of the feed motor or in cooperation with a predetermined strategy. In this implementation the tension motor directly drives the spindle through a speed reducer, rather than through the "lever form" of the tension arm, and can also be considered as a simplified form of embodiment of the tension arm. The speed reducer can effectively amplify motor torque, and can be omitted under the condition that motor performance allows.

In addition, on the basis of the foregoing control scheme, the cutting head assembly 50 may further include a spray assembly 50c, where the spray assembly 50c is disposed on the mounting plate 502, and the spray assembly 50 may include a rotary spray nozzle 509 and a spray pipe, where the rotary spray nozzle 509 may be used to clean each cutting wheel of the cutting wheel set and the ring wire 505, and the spray pipe may be used to spray cooling lubricant to the cutting area of the ring wire 505. In addition, in the cutting process, cooling lubricating liquid (such as water) can be continuously sprayed to a cutting processing area (comprising a silicon rod, an annular wire cutting part and a cutting area thereof) through a spray pipe of the spray device so as to act on the annular wire cutting part and the surface of the silicon rod, and the cooling lubricating liquid can also play a cleaning role at the same time and can also timely clean impurities such as silicon powder and the like on each cutting wheel of the cutting wheel set and each annular wire after the cutting processing is finished. On this basis, in order to fully exert the cooling, lubricating and cleaning effects of the spray assembly 50c, the rotary spray nozzles 509 may be disposed between the cutting wheels, that is, the positions of the rotary spray nozzles 509 are surrounded by the cutting wheels, so that when the rotary spray nozzles 509 work and rotate, the cutting wheels and the corresponding ring wire areas can be covered, and the cleaning effect is further improved. And the shower may be positioned adjacent to the top side of a machining pocket (the pocket being used to accommodate a silicon rod as it is being cut by the cutting head during machining) on the mounting plate 502 to facilitate alignment with the cutting machining area. In order to further enhance the cooling and lubrication effects of the shower, the shower may further include a main shower 510, a first sub-shower 511 and a second sub-shower 512, wherein the main shower 510 is disposed adjacent to a top middle region of the processing accommodating groove on the mounting plate 502, and the first sub-shower 511 and the second sub-shower 512 are disposed at both sides of the main shower 510, respectively, such that one main and two sub-shower are disposed right above the cutting region, thereby being capable of further enhancing the cooling and lubrication effects.

Correspondingly, the control system can also comprise electromagnetic valves, the electromagnetic valves are arranged on pipelines between the supply source (such as water or other supply sources of cooling lubricating liquid) and the spraying component 50c, the controller is also used for controlling the on-off state of the electromagnetic valves, so that the spraying function of the spraying wheel component can be started according to different working states, the number of the electromagnetic valves can be multiple in order to ensure the spraying effect and accurate control, the supply source is respectively connected with the water inlets of the electromagnetic valves through the shunt tubes, the water outlets of the electromagnetic valves are respectively communicated with the rotary spray heads 409 and the spraying pipes, and the controller can respectively control the opening and closing of the rotary spray heads and the spraying pipes by controlling the on-off state of the electromagnetic valves.

In addition, the controller of the control system can be further used for controlling the driving wheel driving motor 518, that is, in the working process, if the tensioning is excessive or the tensioning change is too large due to specific conditions, the controller can correspondingly adjust the driving of the driving wheel driving motor, and reduce the rotating speed of the driving wheel to correspondingly adjust the linear speed of the endless wire; such control of the capstan drive motor may be performed separately from control of the feed motor and control of the tension motor, or may be performed in cooperation with a predetermined strategy.

In summary, the control system for the cutting device according to the embodiment of the application can cover more control surfaces besides the technical effects mentioned above, so that the control precision and the control quality of the silicon rod processing can be further improved, and the control system can be more suitable for different operation requirements. In addition, since the control system for the cutting device has the aforementioned technical effects, the cutting device also has corresponding technical effects, and will not be described herein.
