Description

Technical Field

[0001] This application relates to the field of hard material cutting technology, and more specifically, to a correction method and cutting equipment for diamond wire cutting. Background Technology

[0002] A photovoltaic diamond wire slicing machine is a specialized device that uses diamond wire as a cutting tool to cut monocrystalline silicon rods into silicon wafers of a specific thickness. In the fields of photovoltaic crystalline silicon and semiconductor cutting, photovoltaic diamond wire slicing machines with single-wire or multi-wire diamond wires are commonly used to cut, squared, and slice silicon materials to obtain the corresponding silicon wafers or silicon materials.

[0003] In the cutting process of a photovoltaic diamond wire slicing machine, diamond wires are spirally arranged at a certain distance on multiple main rollers to form a cutting wire mesh. Driven by a motor, the main rollers cause the wire mesh to move unidirectionally or bidirectionally under the action of friction. The unidirectional or bidirectional reciprocating motion of the diamond wires is actually the process of the diamond wires reciprocating between the feed roller and the take-up roller. The bidirectional reciprocating motion of the cutting wire mesh completes the multi-wire cutting of the silicon rod.

[0004] The mismatch between the winding parameters of the new wire on the feed roller and the wire laying parameters of the slicer causes the first section of diamond wire released from the feed roller to deviate from the vertical position and tilt. If the deviation is not corrected in time, it will lead to abnormal wear of the diamond wire and abnormal wire breakage during the cutting process. Summary of the Invention

[0005] The purpose of this application is to provide a correction method and a cutting device for diamond wire cutting equipment. The correction method of this application can correct the deviation of the cutting wire in a timely manner during the wire running process, effectively improve the situation of the cutting wire tilting during the wire running process, and improve the cutting efficiency of the cutting wire.

[0006] In a first aspect, this application provides a correction method for a diamond wire cutting device, applied to the cutting device, the cutting device including a cutting system, the cutting system including a target wire wheel, the cutting wire being wound on the target wire wheel, the correction method for the diamond wire cutting device including: obtaining the tilt direction of the cutting wire relative to a reference state through a cutting wire detection device; the reference state refers to the cutting wire being perpendicular to the main axis of the target wire wheel; and controlling the target wire wheel to move according to the tilt direction so that the cutting wire is perpendicular to the main axis of the target wire wheel.

[0007] In the above technical solution, the tilt direction of the cutting line relative to the reference state is detected by a cutting line detection device. The correction method effectively improves the situation where the cutting line tilts during its running process, thereby increasing the cutting efficiency.

[0008] In one embodiment, the target thread reel includes a pay-off roller and a winding reel; the cutting line detection device is a tension sensor, which is disposed on the winding reel; controlling the target thread reel to move according to the inclination direction of the cutting line relative to a reference state so that the cutting line tends to be perpendicular to the main shaft of the target thread reel includes: acquiring the change value of the tension detected on the tension sensor when the cutting line is tilted relative to the reference state; determining the winding speed value of the winding reel based on the relationship between the change value of the tension and a preset tension change threshold, and the moving direction of the winding reel when winding; and controlling the motor speed of the winding reel based on the winding speed value so that the cutting line tends to be perpendicular to the main shaft of the pay-off roller.

[0009] In the above technical solution, the motor speed of the wire guide wheel is controlled by the electronic control system, thereby changing the moving speed of the wire guide wheel so that the cutting wire and the main shaft of the wire guide wheel tend to be perpendicular, improving the situation of abnormal wire breakage and thus improving the tension difference caused by factors such as the oblique pulling of the cutting wire.

[0010] In one embodiment, the target thread reel further includes a tension reel for adjusting the tension of the cutting wire on the thread reel; the change in tension value includes a change in tension value in a first direction and a change in tension value in a second direction; obtaining the change in tension value detected by the tension sensor when the cutting wire tilts relative to the reference state includes: obtaining the initial tension value detected by the tension sensor when the motor of the tension reel is in constant torque output and the cutting wire is in the reference state; obtaining the tension value in the first direction detected by the tension sensor when the cutting wire tilts relative to the reference state in a first direction; determining the change in tension value in the first direction based on the difference between the initial tension value and the tension value in the first direction; or, obtaining the initial tension value detected by the tension sensor when the motor of the tension reel is in constant torque output and the cutting wire is in the reference state; obtaining the tension value in the second direction detected by the tension sensor when the cutting wire tilts relative to the reference state in a second direction; determining the change in tension value in the second direction based on the difference between the tension value in the second direction and the initial tension value.

[0011] In the above technical solution, the tension sensor can accurately detect the initial tension value when the cutting line is in the reference state, as well as the tension value when the cutting line is tilted relative to the reference state, so as to determine the change in tension value on the cutting line after tilting in a timely and accurate manner.

[0012] In one embodiment, determining the cable laying speed value of the cable laying wheel based on the relationship between the change in the tension value and a preset tension change threshold, and the direction of movement of the cable laying wheel during cable laying, includes: determining that the cable laying speed value of the cable laying wheel is greater than zero when the change in the tension value in the first direction is greater than the preset tension change threshold and the cable laying wheel moves in the first direction; determining that the cable laying speed value of the cable laying wheel is less than zero when the change in the tension value in the first direction is greater than the preset tension change threshold and the cable laying wheel moves in the second direction; determining that the cable laying speed value of the cable laying wheel is less than zero when the change in the tension value in the second direction is greater than the preset tension change threshold and the cable laying wheel moves in the first direction; and determining that the cable laying speed value of the cable laying wheel is greater than zero when the change in the tension value in the second direction is greater than the preset tension change threshold and the cable laying wheel moves in the second direction.

[0013] In the above technical solution, by determining the relationship between the change value of the tension value and the preset tension change threshold, as well as the moving direction of the wire feeding wheel when feeding the wire, the wire feeding speed value of the wire feeding wheel can be quickly and accurately determined, so that the force on the cutting wire on the wire feeding roller and the wire feeding wheel is kept in a dynamic equilibrium state, thus improving the phenomenon of wire slant.

[0014] In one embodiment, the target thread reel includes a pay-off roller and a winding reel, and the cutting line detection device is an image acquisition device disposed between the pay-off roller and the winding reel. Controlling the target thread reel to move according to the tilt direction so that the cutting line tends to be perpendicular to the main shaft of the target thread reel includes: acquiring an image of the tilt state of the cutting line acquired by the image acquisition device; determining, based on the tilt state image, the tilt direction of the cutting line relative to the reference state and a first angle between the direction in which the cutting line is perpendicular to the main shaft of the pay-off roller; determining the winding speed value of the winding reel based on the relationship between the first angle and a first preset angle threshold, and the moving direction of the winding reel during winding; and controlling the motor speed of the winding reel based on the winding speed value so that the cutting line tends to be perpendicular to the main shaft of the pay-off roller.

[0015] In the above technical solution, by acquiring images of the tilt state of the cutting line through an image acquisition device, the tilt direction of the cutting line relative to the reference state can be determined quickly, intuitively, and accurately.

[0016] In one embodiment, determining the tracing speed value of the tracing wheel based on the relationship between the first included angle and a first preset included angle threshold, and the moving direction of the tracing wheel during tracing, includes: determining that the tracing speed value of the tracing wheel is greater than zero when the cutting line is inclined in a first direction relative to the reference state, the first included angle is greater than the first preset included angle threshold, and the tracing wheel moves in the first direction; determining that the tracing speed value of the tracing wheel is less than zero when the cutting line is inclined in a second direction relative to the reference state, the first included angle is greater than the first preset included angle threshold, and the tracing wheel moves in the first direction; determining that the tracing speed value of the tracing wheel is less than zero when the cutting line is inclined in a first direction relative to the reference state, the first included angle is greater than the first preset included angle threshold, and the tracing wheel moves in the second direction; and determining that the tracing speed value of the tracing wheel is greater than zero when the cutting line is inclined in a second direction relative to the reference state, the first included angle is greater than the first preset included angle threshold, and the tracing wheel moves in the second direction.

[0017] In the above technical solution, by determining the relationship between the first included angle and the first preset included angle threshold, and the moving direction of the wire feeding wheel when feeding the wire, the wire feeding speed value of the wire feeding wheel can be quickly and accurately determined, so that the force on the cutting wire on the wire feeding roller and the wire feeding wheel is kept in a dynamic balance state, thereby improving the phenomenon of the cutting wire being pulled at an angle.

[0018] In one embodiment, the target thread reel includes a feed roller and a reversing roller; the cutting line detection device is an encoder, which is mounted on the reversing roller. When the cutting line is tilted, it drives the reversing roller to rotate, thereby causing the encoder to deflect; controlling the target thread reel to move according to the tilt direction so that the cutting line and the main shaft of the target thread reel tend to be perpendicular includes: obtaining the deflection angle of the encoder; determining, according to the deflection angle, a second angle between the tilt direction of the cutting line relative to the reference state and the direction perpendicular to the main shaft of the feed roller; determining the thread laying speed value of the feed roller according to the relationship between the second angle and a second preset angle threshold and the moving direction of the feed roller when laying the thread; and controlling the motor speed of the feed roller according to the thread laying speed value so that the cutting line and the main shaft of the feed roller tend to be perpendicular.

[0019] In the above technical solution, the tilt direction of the cutting line can be quickly and accurately determined by the deflection angle of the encoder. Based on the tilt direction of the cutting line, the speed and direction of the feed roller are adjusted to keep the force on the cutting line on the feed roller and the reversing wheel in dynamic balance, thereby improving the tension difference caused by factors such as the oblique pull of the cutting line.

[0020] In one embodiment, determining the wire laying speed value of the wire laying roller based on the relationship between the second included angle and the second preset included angle threshold, and the moving direction of the wire laying roller during wire laying, includes: determining that the wire laying speed value of the wire laying roller is less than zero when the reversing wheel is tilted in a first direction relative to the reference state, the second included angle is greater than the second preset included angle threshold, and the wire laying roller moves in the first direction; determining that the wire laying speed value of the wire laying roller is greater than zero when the reversing wheel is tilted in a second direction relative to the reference state, the second included angle is greater than the second preset included angle threshold, and the wire laying roller moves in the first direction; determining that the wire laying speed value of the wire laying roller is greater than zero when the reversing wheel is tilted in a first direction relative to the reference state, the second included angle is greater than the second preset included angle threshold, and the wire laying roller moves in the second direction; and determining that the wire laying speed value of the wire laying roller is less than zero when the reversing wheel is tilted in a second direction relative to the reference state, the second included angle is greater than the second preset included angle threshold, and the wire laying roller moves in the second direction.

[0021] In the above technical solution, by determining the relationship between the second included angle and the second preset included angle threshold, and the moving direction of the wire feeding roller when feeding the wire, the wire feeding speed value of the wire feeding roller can be quickly and accurately determined, so that the force of the cutting line on the wire feeding roller and the reversing wheel is kept in a dynamic balance state, thereby improving the oblique pulling phenomenon of the cutting line.

[0022] In one embodiment, obtaining the tilt direction of the cutting line relative to a reference state through the cutting line detection device includes: obtaining an electrical signal generated when the cutting line detection device contacts the cutting line in the detection area; and determining the tilt direction of the cutting line relative to the reference state based on the electrical signal.

[0023] In the above technical solution, the cutting line is detected by the cutting line detection device during the running process. Based on the electrical signal generated after the cutting line is sensed by the cutting line detection device, the direction of the cutting line tilt can be accurately and quickly determined.

[0024] In one embodiment, the cutting line detection device includes: a first sensor, a second sensor, and a driving unit; the driving unit is connected to the first sensor and the second sensor, the first sensor is located to the left of the cutting line in a reference state, and the second sensor is located to the right of the cutting line in the reference state; acquiring the electrical signal generated when the cutting line detection device contacts the cutting line in the detection area includes: controlling the driving unit to drive the first sensor and the second sensor from an open state to a closed state; acquiring the electrical signal generated when the first sensor and the second sensor contact the cutting line in the detection area during the closing process.

[0025] In the above technical solution, the opening and closing action is achieved by driving the first and second sensors through the driving unit. During the closing process of the first and second sensors, the electrical signal generated when either sensor comes into contact with the cutting wire can be used to quickly determine the tilt direction of the diamond wire. This method of detecting the cutting wire is simpler and faster.

[0026] In one embodiment, determining the tilt direction of the cutting line relative to a reference state based on the electrical signal includes: determining that the cutting line is tilted to the left relative to the reference state when the electrical signal generated by the first sensing element contacting the cutting line is obtained; and determining that the cutting line is tilted to the right relative to the reference state when the electrical signal generated by the second sensing element contacting the cutting line is obtained.

[0027] In the above technical solution, the current tilt direction of the cutting line can be quickly and accurately determined based on the position of the sensing element that triggers the electrical signal.

[0028] In one embodiment, the cutting line detection device further includes a moving component connected to the driving unit. The method further includes: when the electrical signal generated by the first sensing element contacting the cutting line is obtained, controlling the moving component to move in the direction of the first sensing element so that the cutting line is between the first sensing element and the second sensing element; and when the electrical signal generated by the second sensing element contacting the cutting line is obtained, controlling the moving component to move in the direction of the second sensing element so that the cutting line is between the first sensing element and the second sensing element.

[0029] In the above technical solution, the current tilt direction of the cutting line can be quickly determined based on the position of the sensor that triggers the electrical signal. Based on the tilt direction of the cutting line, the moving component is controlled to move the cutting line towards the direction of the sensor that generates the electrical signal, thereby achieving the correction of the cutting line's tilt.

Detailed Implementation

[0059] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0060] Similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0061] Please refer to Figure 1 This application provides a cutting device, including a cutting system 11 and an electrical control system 12; the electrical control system 12 is electrically connected to the cutting system 11. The cutting system 11 is used to cut hard materials, such as photovoltaic silicon rods, crystalline silicon, semiconductors, gemstones, magnetic materials, etc. The electrical control system 12 is used to control the cutting system 11 to cut the hard materials.

[0062] Furthermore, the cutting system 11 includes target spools. Based on the different functions and roles of each target spool, the cutting system 11 can be divided into three zones: the pay-off zone 111, the cutting zone 112, and the take-up zone 113.

[0063] The wire feeding area 111 includes: a wire feeding roller 1111, a wire feeding reel 1112, a tension wheel 1113, and a reversing wheel 1114. The wire feeding roller 1111 is the wire feeding reel for winding the cutting wire, driven by a motor to achieve wire feeding. The wire feeding reel 1112 is the wire feeding reel for guiding the cutting wire. A tension sensor is installed on the wire feeding reel 1112 to detect the tension value on the cutting wire. It can also be driven by a linear drive module to perform linear reciprocating motion along the main axis of the wire feeding roller 1111. The function of the wire feeding reel 1112 is to guide the cutting wire out or into the target wire reel, and to move with the rotation of the target wire reel, so that the entry and exit points of the cutting wire are perpendicular to the main axis of the wire feeding roller 1111. The tension wheel 1113 is used to adjust the tension of the cutting wire on the wire feeding reel 1112. The reversing wheel 1114 is used for multi-directional rotation adjustment of the cutting wire. The linear drive module can be fixedly mounted on the wire feeding reel bracket. In some implementations, the linear drive module can be one of the following: a lead screw motor and slider assembly, a linear motor module, a gear and rack transmission assembly, a cylinder, a hydraulic cylinder, etc.

[0064] The cutting wire is wound between the feed roller 1111, the wire guide roller 1112, the tension roller 1113, and the reversing roller 1114. Specifically, the cutting wire is wound on the feed roller 1111 and then onto the upper wire guide roller 1112. The wire guide roller 1112 is installed between the feed roller 1111 and the tension roller 1113 to allow the cutting wire to be laid out on the feed roller 1111 at a certain pitch. The cutting wire is guided by the wire guide roller 1112 and wound onto the tension roller 1113. It is then guided by the tension roller 1113 to the reversing roller 1114, and then rotated and adjusted by the reversing roller 1114 to guide it into the cutting area 112. In some other embodiments, the cutting wire can be directly guided into the cutting area 112 by the wire guide roller 1112 and the tension roller 1113.

[0065] The cutting zone 112 includes at least two parallel main rollers 1121. The main rollers 1121 are thread wheels used to wind the cutting wire to form a cutting wire mesh 1122. The cutting wire is adjusted, transmitted, and guided from the feed zone 111 through the feed roller 1111, the wire feeding wheel 1112, and the tension wheel 1113 to the reversing wheel 1114, and then guided by the reversing wheel 1114 to the main rollers 1121, and is repeatedly wound multiple times on the two parallel main rollers 1121.

[0066] To prevent the cutting wire from deviating during winding on the main roller 1121, multiple grooves are typically provided on the main roller 1121 to accommodate the cutting wire and limit its position. After rewinding, a cutting wire mesh 1122 for cutting is formed on the two main rollers 1121. The end cutting wire after winding on the main roller 1121 passes through the take-up area 113.

[0067] The take-up zone 113 includes a guide roller 1131 and a take-up roller 1132. The guide roller 1131 is located between the main roller 1121 and the take-up roller 1132 and is used to change the direction of the cut wire so that the cut wire can be smoothly wound onto the take-up roller 1132. Typically, the number of guide rollers 1131 is ≥1. Tension rollers and reversing rollers can be collectively referred to as guide rollers. The take-up roller 1132 is a spool used to wind the used cut wire.

[0068] In the cutting system 11 of this embodiment, the cutting wire is wound around the feed roller 1111, the feed wheel 1112, the tension wheel 1113 and the reversing wheel 1114, respectively, and is guided into the main roller 1121. After passing through the main roller 1121, the wire is wound around multiple times to form a cutting wire mesh 1122, and then passes through the take-up roller 1132 of the pass wheel 1131. The take-up roller 1132 then collects the cut wire.

[0069] For example, the cutting wire is diamond wire, which includes high-carbon steel wire and tungsten wire. According to the diamond wire cutting principle, the electronic control system 12 controls the cutting system 11 to run the wire sequentially from the wire feeding area 111 to the cutting area 112 and then to the wire take-up area 113. When the diamond wire on all the wire wheels in the cutting system 11 is running at high speed, the hard material to be cut is controlled to be lowered onto the cutting wire mesh 1122. Under the pressure applied to the hard material, the diamond wire is pressed into the bottom surface of the hard material to cut the hard material and form a slice.

[0070] Please refer to Figure 2 The electronic device 2 includes at least one processor 22 and a memory 23, taking one processor 22 as an example. The processor 22 and the memory 23 are connected via a bus 21. The memory 23 stores instructions that can be executed by the processor 22. The instructions are executed by the processor 22 to enable the electronic device 2 to perform all or part of the silicon wafer dicing method described in the following embodiments. In one embodiment, the electronic device 2 may be the electrical control system 12 of the dicing equipment 1, or it may be another device independent of the dicing equipment 1. The electronic device 2 can control the dicing equipment 1.

[0071] The memory 23 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable red-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk or optical disk.

[0072] During the reciprocating motion of the diamond wire between the feeding zone 111, the cutting zone 112, and the take-up zone 113, a certain error exists between the actual wire spacing on the spool and the theoretical wire spacing of the cutting system. This causes the diamond wire to become skewed or tilted during the motion. This deviation gradually accumulates and increases with continuous wire movement, exacerbating the skew or tilting problem. Skewed diamond wire can easily lead to friction at the edge of the spool, reducing the cutting force and increasing the probability of wire breakage, ultimately affecting the cutting efficiency and the quality of the cut products.

[0073] Therefore, in order to improve the situation of diamond wire misalignment, reduce the probability of diamond wire breakage, and improve the cutting efficiency of diamond wire, this application provides a correction method for diamond wire cutting equipment, which is used to correct the diamond wire misalignment during the wire running process of the diamond wire cutting equipment and improve the situation of diamond wire misalignment.

[0074] Please suffer the terrible fate Figure 3 The correction method for the diamond wire cutting equipment provided in this application may specifically include: steps S310-S320:

[0075] Step S310: Obtain the tilt direction of the cutting line relative to the reference state through the cutting line detection device 13; the reference state refers to the cutting line being perpendicular to the spindle of the target thread wheel.

[0076] As mentioned earlier, the cutting wire is taken as a diamond wire. The diamond wire is wound in multiple turns on the target wire reel and laid out according to the preset actual wire spacing. The preset actual wire spacing can be stored in the aforementioned memory 23. Before the cutting system 11 starts cutting, the electronic control system 12 retrieves the wire spacing from the memory 23 and controls the cutting system 11 to lay out the wire according to the actual wire spacing.

[0077] As the length of the diamond wire increases, the diamond wire may tilt relative to the spindle of the target spool. This tilting can be detected in a timely manner by the wire cutting detection device 13.

[0078] In theory, if the actual wire spacing on the target wire reel matches the theoretical wire spacing of the cutting system 11, i.e. there is no error between them, then when the electronic control system 12 controls the cutting system 11 to feed the wire according to the theoretical wire spacing, the actual wire spacing on the target wire reel should be consistent with the theoretical wire spacing. When the electronic control system 12 controls the feeding roller 1111 to feed the wire, the wire in and out of the diamond wire tends to be perpendicular to the main axis direction of the feeding roller 1111, and there will be no oblique pulling phenomenon.

[0079] However, due to objective factors such as the material of the diamond wire, the rotation speed of the target wire wheel, and the equipment parameters of the cutting system 11, there is a certain error between the actual wire spacing on the target wire wheel and the theoretical wire spacing. As the diamond wire is used for a normal distance, the error between the actual wire spacing on the target wire wheel and the theoretical wire spacing of the cutting system 11 will gradually accumulate and increase, resulting in serious diagonal pulling of the diamond wire.

[0080] Please refer to Figure 4 As shown, when the diamond wire tilts, there is an angle between it and the reference state. The angle may include... Figure 4 The angles θ1 and θ2 shown are given. Angles θ1 and θ2 can represent two different tilt directions of the cutting line relative to the reference state.

[0081] Step S320: Control the target thread wheel to move according to the tilt direction so that the cutting line is perpendicular to the spindle of the target thread wheel.

[0082] In step S10, the tilt direction of the diamond wire relative to the reference state is detected by the cutting wire detection device 13, and the direction in which the target thread wheel should move can be determined based on the tilt direction of the diamond wire. By controlling the movement of the target thread wheel, the entry and exit of the diamond wire are adjusted so that the diamond wire and the spindle of the target thread wheel tend to be perpendicular.

[0083] It should be noted that the "perpendicular" mentioned in this application is a description of the state relationship between the spindle axis of the target thread reel and the running direction of the diamond thread, and is not a perpendicular relationship as described in plane, space or geometric relationships.

[0084] In some embodiments, please refer to Figure 5 As shown, the target reel includes: a feed roller 1111 and a wire feeding reel 1112; the wire cutting detection device 13 is a tension sensor, which is mounted on the wire feeding reel 1112. Step S320 may specifically include: steps S321-S323:

[0085] Step S321: Obtain the change in tension value detected by the tension sensor when the cutting line is tilted relative to the reference state from the reference state.

[0086] The working principle of a tension sensor is to use a strain gauge to sense the strain change of the diamond wire being measured. The resistance value of the strain gauge changes accordingly. The strain change of the strain gauge is converted into an electrical signal by a circuit. After being amplified and processed by a transmitter circuit, the output is an electrical signal proportional to the force change, thus completing the force detection.

[0087] When the diamond wire is in the reference state, the tension value of the diamond wire on the wire feeding roller 1111 and the tension roller 1113 can be detected by the tension sensor.

[0088] When the diamond wire tilts relative to the reference state, the tension of the diamond wire acting on the wire guide wheel 1112 will change. The tension value of the diamond wire on the wire guide wheel 1112 can also be detected by the tension sensor.

[0089] The difference between two tension values ​​detected by the tension sensor can be expressed as the change between the tension value detected when the diamond wire is in a reference state and the tension value detected when the diamond wire is in an inclined state.

[0090] Step S322: Determine the wire-laying speed value of the wire-laying wheel based on the relationship between the change value of the tension value and the preset tension change threshold, as well as the moving direction of the wire-laying wheel when laying the wire.

[0091] After detecting the change in tension value, the change in tension value is compared with the preset tension change threshold. Based on the relationship between the change in tension value and the preset tension change threshold, as well as the moving direction of the wire guide wheel 1112 when wire is being wired, the wire guide speed value of the wire guide wheel 1112 is determined.

[0092] Step S323: Control the motor speed of the wire feeding wheel according to the wire feeding speed value so that the cutting wire and the main shaft of the feeding roller tend to be perpendicular.

[0093] The wire guide wheel 1112 can be driven by a motor screw drive assembly, a linear drive module, a rack and pinion transmission assembly, or other structures to achieve reciprocating left and right movement in the horizontal direction. Taking the motor screw drive structure as an example, to achieve rapid horizontal movement of the wire guide wheel 1112, the electrical control system 12 can control the motor speed to increase, making the motor rotation frequency of the wire guide wheel 1112 higher, thereby accelerating the movement speed of the wire guide wheel 1112. Conversely, to achieve slow horizontal movement of the wire guide wheel 1112, the electrical control system 12 can control the motor speed to decrease, making the motor rotation frequency of the wire guide wheel 1112 lower, thereby slowing down the movement speed of the wire guide wheel.

[0094] If the wire laying speed of the wire laying wheel 1112 is too high, and the moving speed of the wire laying wheel 1112 is too fast, the wire laying speed of the diamond wire cannot keep up with the moving speed of the wire laying wheel 1112, and the diamond wire is prone to tilting. To improve this phenomenon, the motor speed of the wire laying wheel 1112 can be reduced by controlling the electronic control system 12 to reduce the motor rotation frequency of the wire laying wheel 1112, thereby slowing down the moving speed of the wire laying wheel 1112, so that the force on the diamond wire on the wire laying wheel 1112 is kept in a dynamic balance, so that the diamond wire tends to be perpendicular to the main shaft of the wire laying roller 1111.

[0095] In some embodiments, the target reel includes: a pay-off roller 1111, a wire feeding reel 1112, and a tension reel 1113. Step S321 may specifically include steps S3211-S3216:

[0096] Step S3211: Obtain the initial tension value detected by the tension sensor when the motor of the tension wheel is in constant torque output state and the cutting line is the reference state;

[0097] Step S3212: Obtain the tension value detected by the tension sensor in the first direction when the cutting line is tilted in the first direction relative to the reference state;

[0098] Step S3213: Determine the change in the tension value in the first direction based on the difference between the initial tension value and the tension value in the first direction;

[0099] or,

[0100] Step S3214: Obtain the initial tension value detected by the tension sensor when the motor of the tension wheel is in constant torque output state and the cutting line is the reference state;

[0101] Step S3215: Obtain the tension value detected by the tension sensor in the second direction when the cutting line is tilted in the second direction relative to the reference state;

[0102] Step S3216: Determine the change in the second-direction tension value based on the difference between the second-direction tension value and the initial tension value.

[0103] like Figure 5 As shown, the tilting of the diamond wire relative to the reference state includes two scenarios: the first scenario is that the diamond wire tilts in a first direction relative to the reference state; the second scenario is that the diamond wire tilts in a second direction relative to the reference state. In this embodiment, the first direction is defined as the diamond wire tilting to the right relative to the reference state with a tilt angle of θ2, and the second direction is defined as the diamond wire tilting to the left relative to the reference state with a tilt angle of θ1.

[0104] When the diamond wire is used as the reference state, the tension value detected by the tension sensor is taken as the initial tension value and can be recorded as F0. Based on the calculation of the resultant force of the parallelogram, it can be seen that when the diamond wire is tilted in the first direction relative to the reference state, the tension value detected by the tension sensor in the first direction can be recorded as F1, which is smaller than the initial tension value; conversely, when the diamond wire is tilted in the second direction relative to the reference state, the tension value detected by the tension sensor in the second direction can be recorded as F2, which is larger than the initial tension value.

[0105] Therefore, in steps S3211-S3213, when the diamond wire is tilted in the first direction relative to the reference state, the change value of the tension in the first direction, i.e., F0-F1, can be determined based on the difference between the initial tension value and the tension value in the first direction.

[0106] In steps S4214-S4216, when the diamond wire is tilted in the second direction relative to the reference state, the change in the tension value in the second direction, i.e., F2-F0, can be determined based on the difference between the tension value in the second direction and the initial tension value.

[0107] As mentioned earlier, the preset tension change threshold can be denoted as ΔF. When F0-F1>ΔF or F2-F0>ΔF, it indicates that the diamond wire is tilted on the pay-off roller 1111. At this time, the wire feeding speed compensation of the wire feeding wheel 1112 can be performed to keep the force on the diamond wire on the pay-off roller 1111 and the wire feeding wheel 1112 in a balanced state, so as to improve the oblique pulling phenomenon of the diamond wire on the pay-off roller 1111 and make the diamond wire and the main axis of the pay-off roller 1111 tend to be perpendicular.

[0108] Therefore, further, step S322 may specifically include: steps S3221-S3224:

[0109] Step S3221: When the change in tension value in the first direction is greater than the preset tension change threshold, and the cable guide wheel moves in the first direction, determine that the cable guide wheel's cable speed value is greater than zero.

[0110] When F0-F1>△F, the diamond wire tilts to the right relative to the reference state on the pay-off roller, and the wire guide wheel 1112 is moving from left to right, the wire guide speed of the wire guide wheel 1112 should be increased to speed up its movement. This will keep the forces on the diamond wire on the pay-off roller 1111 and the wire guide wheel 1112 in a balanced state, so that the diamond wire guided out by the wire guide wheel 1112 remains perpendicular to the main shaft of the pay-off roller 1111.

[0111] It should be noted that a wire-laying speed value greater than zero for wire-laying reel 1112 indicates an increase in wire-laying speed, while a value less than zero indicates a decrease in wire-laying speed. The same applies below, and will not be elaborated further.

[0112] Step S3222: When the change in tension value in the first direction is greater than the preset tension change threshold, and the cable guide wheel moves in the second direction, determine that the cable guide wheel's cable speed value is less than zero.

[0113] When F0-F1>△F, the diamond wire tilts to the right relative to the reference state on the pay-off roller, and the wire guide wheel 1112 is moving from right to left, the wire guide wheel speed should be reduced to slow down the movement of the wire guide wheel 1112, so that the forces on the diamond wire on the pay-off roller 1111 and the wire guide wheel 1112 are kept in a balanced state, thereby ensuring that the diamond wire guided out by the wire guide wheel 1112 is perpendicular to the main shaft of the pay-off roller 1111.

[0114] Step S3223: When the change in the tension value in the second direction is greater than the preset tension change threshold, and the cable guide wheel moves in the first direction, determine that the cable guide wheel's cable speed value is less than zero.

[0115] When F2-F0>△F, the diamond wire tilts to the left relative to the reference state on the pay-off roller, and the wire guide wheel 1112 is moving from left to right, the wire guide speed of the wire guide wheel 1112 should be reduced to slow down the movement of the wire guide wheel 1112, so that the forces on the diamond wire on the pay-off roller 1111 and the wire guide wheel 1112 are kept in a balanced state, so that the diamond wire guided out by the wire guide wheel 1112 tends to be perpendicular to the main axis of the pay-off roller 1111.

[0116] Step S3224: When the change in the tension value in the second direction is greater than the preset tension change threshold, and the cable guide wheel moves in the second direction, determine that the cable guide wheel's cable speed value is greater than zero.

[0117] When F2-F0>△F, the diamond wire tilts to the left relative to the reference state on the pay-off roller, and the wire guide wheel 1112 is moving from right to left, the wire guide speed of the wire guide wheel 1112 should be increased to speed up its movement. This will keep the forces on the diamond wire on the pay-off roller 1111 and the wire guide wheel 1112 in a balanced state, so that the diamond wire guided out by the wire guide wheel 1112 remains perpendicular to the main axis of the pay-off roller 1111.

[0118] In the above steps, by determining the relationship between the change value of the tension value and the preset tension change threshold, as well as the moving direction of the wire feeding wheel 1112 when feeding the wire, the wire feeding speed value of the wire feeding wheel is quickly and accurately determined, so that the force on the diamond wire on the wire feeding roller 1111 and the wire feeding wheel 1112 is kept in a dynamic equilibrium state.

[0119] In some embodiments, please refer to Figure 6 As shown, the target thread reel includes a feed roller 1111 and a guide roller 1112. The cutting line detection device 13 is an image acquisition device. The image acquisition device is located between the feed roller 1111 and the guide roller 1112. The image acquisition device can be mounted on a linear drive module, which can drive the image acquisition device to reciprocate along the main axis of the feed roller 1111. The guide roller 1112 can also be mounted on the linear drive module together with the image acquisition device, so that the guide roller 1112 and the image acquisition device move together. The image acquisition device can be a photographic device, video camera, or other device capable of capturing images.

[0120] Furthermore, step S320 may specifically include: steps S324-S327:

[0121] Step S324: Acquire the image of the tilt state of the cutting line acquired by the image acquisition device.

[0122] Using the baseline at the center of the field of view of the image acquisition device as a reference center, the baseline can be represented by a cross. When the diamond wire is within the acquisition field of view of the image acquisition device, if the positional information of the diamond wire acquired by the image acquisition device shows that the diamond wire is tilted to the left or right relative to the baseline at the center of the field of view, and does not coincide with the baseline at the center of the field of view, it indicates that the diamond wire is in a tilted state.

[0123] An image acquisition device is provided to capture images of the tilt state of the diamond wire, enabling quick, intuitive, and accurate determination of the tilt direction of the diamond wire relative to a reference state.

[0124] Step S325: Based on the tilt state image, determine the tilt direction of the cutting line relative to the reference state and the first included angle between the cutting line and the direction perpendicular to the main shaft of the feeding roller.

[0125] The tilt direction of the diamond wire can be determined by its tilt relative to the baseline at the center of the field of view. For example, please refer to... Figure 6 As shown, when the diamond wire shifts to the left relative to the baseline of the center of the field of view, it indicates that the diamond wire is tilted to the left at this time, and the first included angle between the diamond wire and the direction perpendicular to the main axis of the pay-off roller 1111 is determined to be α1; when the diamond wire shifts to the right relative to the baseline of the center of the field of view, it indicates that the diamond wire is tilted to the right at this time, and the first included angle between the diamond wire and the direction perpendicular to the main axis of the pay-off roller 1111 is determined to be α2. Figure 6 Take the example of the diamond wire tilting to the left.

[0126] Step S326: Determine the cable laying speed value of the cable laying wheel based on the relationship between the first included angle and the first preset included angle threshold, and the moving direction of the cable laying wheel when laying the cable.

[0127] The first preset included angle threshold can be denoted as α0. After detecting the first included angle after the diamond wire tilts relative to the baseline of the center of the field of view, the first included angle is compared with the first preset included angle threshold. Based on the relationship between the first included angle and the first preset included angle threshold, and the moving direction of the wire guide wheel 1112 when wire guide is performed, the wire guide speed value of the wire guide wheel 1112 is determined.

[0128] Step S327: Control the motor speed of the wire feeding wheel according to the wire feeding speed value so that the cutting wire and the main shaft of the feeding roller tend to be perpendicular.

[0129] The electric control system 12 controls the motor speed of the wire feeding wheel 1112 to decrease, thereby reducing the motor rotation frequency of the wire feeding wheel 1112 and slowing down the moving speed of the wire feeding wheel 1112. This keeps the force of the diamond wire on the wire feeding wheel 1112 in a dynamic balance state, so that the diamond wire tends to be perpendicular to the main shaft of the wire feeding roller 1111.

[0130] In some embodiments, step S326 may specifically include steps S3261-S3264:

[0131] Step S3261: When the cutting line is tilted in the first direction relative to the reference state, the first included angle is greater than the first preset included angle threshold, and the wire guide wheel moves in the first direction, it is determined that the wire guide wheel's wire guide speed value is greater than zero.

[0132] The first direction is defined as right and the second direction as left. When α1 > α0, the diamond wire tilts to the right relative to the reference state, and the wire feeding wheel 1112 is moving from left to right, the wire feeding speed of the wire feeding wheel should be increased to speed up the movement of the wire feeding wheel 1112. This keeps the forces on the diamond wire on the pay-off roller 1111 and the wire feeding wheel 1112 in a balanced state, so that the diamond wire guided out by the wire feeding wheel 1112 is perpendicular to the main axis of the pay-off roller 1111.

[0133] As mentioned earlier, a wire laying speed value greater than zero for the wire laying wheel 1112 indicates an increase in the wire laying speed, while a wire laying speed value less than zero indicates a decrease in the wire laying speed.

[0134] Step S3262: When the cutting line is tilted in the second direction relative to the reference state, the first included angle is greater than the first preset included angle threshold, and the wire guide wheel moves in the first direction, it is determined that the wire guide wheel's wire guide speed value is less than zero.

[0135] When α1 > α0, the diamond wire tilts to the left relative to the reference state, and the wire feeding wheel 1112 is moving from left to right, the wire feeding speed of the wire feeding wheel 1112 should be reduced to slow down the movement speed of the wire feeding wheel 1112, so that the force on the diamond wire on the pay-off roller 1111 and the wire feeding wheel 1112 is kept in a balanced state, so that the diamond wire guided out by the wire feeding wheel 1112 is kept perpendicular to the main shaft of the pay-off roller 1111.

[0136] Step S3263: When the cutting line is tilted in the first direction relative to the reference state, the first included angle is greater than the first preset included angle threshold, and the wire guide wheel moves in the second direction, it is determined that the wire guide wheel's wire guide speed value is less than zero.

[0137] When α1 > α0, the diamond wire tilts to the right relative to the reference state, and the wire feeding wheel 1112 is moving from right to left, the wire feeding speed of the wire feeding wheel 1112 should be reduced to slow down the movement speed of the wire feeding wheel 1112, so that the force on the diamond wire on the pay-off roller 1111 and the wire feeding wheel 1112 is kept in a balanced state, so that the diamond wire guided out by the wire feeding wheel 1112 is kept perpendicular to the main shaft of the pay-off roller 1111.

[0138] Step S3264: When the cutting line is tilted in the second direction relative to the reference state, the first included angle is greater than the first preset included angle threshold, and the wire guide wheel moves in the second direction, it is determined that the wire guide wheel's wire guide speed value is greater than zero.

[0139] When α1 > α0, the diamond wire tilts to the left relative to the reference state, and the wire feeding wheel 1112 is moving from right to left, the wire feeding speed of the wire feeding wheel 1112 should be increased to speed up its movement. This will keep the forces on the diamond wire on the pay-off roller 1111 and the wire feeding wheel 1112 in a balanced state, so that the diamond wire guided out by the wire feeding wheel 1112 remains perpendicular to the main shaft of the pay-off roller 1111.

[0140] In the above steps, by determining the relationship between the first clamping and the first preset angle threshold, and the moving direction of the wire feeding wheel 1112 when feeding the wire, the wire feeding speed value of the wire feeding wheel is quickly and accurately determined, so that the force on the diamond wire on the wire feeding roller 1111 and the wire feeding wheel 1112 is kept in a dynamic equilibrium state.

[0141] In some embodiments, referring to Figures 7(a) and 7(b), the target wire reel includes a pay-off roller 1111 and a reversing roller 1114. The cutting wire detection device 13 is an encoder, which is mounted on the reversing roller 1114. The diamond wire output from the pay-off roller 1111 is guided onto the reversing roller 1114. The encoder can be mounted on the reversing roller 1114 via a bearing assembly. When the diamond wire tilts, it drives the reversing roller 1114 to rotate, thereby causing the encoder to deflect. The pay-off roller 1111 can be driven by a linear drive unit to reciprocate in the direction of its main shaft. The linear drive unit may include a motor screw drive assembly, a linear drive module, a gear and rack transmission assembly, etc.

[0142] Furthermore, step S320 may specifically include: steps S328-S32101:

[0143] Step S328: Obtain the encoder deflection angle.

[0144] When the diamond wire tilts relative to the reference state, this tilt causes the reversing wheel 1114 to deflect. The deflection angle of the reversing wheel 1114 can be detected by an encoder, thus the encoder's deflection angle characterizes the deflection angle of the reversing wheel 1114. Taking the diamond wire in the reference state as the encoder's zero position, as the pay-off roller 1111 continuously pays off the wire, the diamond wire tilts on the pay-off roller 1111. This tilt causes the reversing wheel 1114 to deflect, and the encoder deviates from the zero position by a change in angle, thus characterizing the change in the diamond wire's tilt angle.

[0145] Step S329: Based on the deflection angle, determine the tilt direction of the cutting line relative to the reference state and the second included angle between the cutting line and the direction perpendicular to the main shaft of the feeding roller.

[0146] When the tilt of the diamond wire causes the reversing wheel 1114 to deflect, the tilt direction of the diamond wire can be determined based on the deflection angle detected by the encoder. As shown in Figure 7(a), the deflection angle can be represented by the second included angle α between the diamond wire and the direction perpendicular to the main shaft of the pay-off roller 1111.

[0147] Step S3210: Determine the wire laying speed value of the wire laying roller based on the relationship between the second included angle and the second preset included angle threshold, and the moving direction of the wire laying roller during wire laying.

[0148] After the encoder detects the second included angle α between the diamond wire and the vertical direction of the main shaft of the wire feeding roller 1111, the second included angle is compared with the second preset included angle threshold. Based on the relationship between the second included angle and the second preset included angle threshold, and the moving direction of the wire feeding roller 1111 when feeding the wire, the wire feeding speed value of the wire feeding roller 1111 is determined.

[0149] In this embodiment, the wire feeding roller 1111 can rotate under the drive of the wire feeding motor, and can also move left and right along the main shaft under the drive of the linear drive unit, thus taking into account the wire laying function.

[0150] The second preset included angle threshold can be denoted as a0. As an example, the second preset included angle threshold a0 can be the same as the first preset included angle threshold α0 in the aforementioned step S326.

[0151] In the above steps, the tilt direction of the diamond wire can be quickly and accurately determined by the deflection angle of the encoder. Based on the tilt direction of the diamond wire, the speed and direction of the pay-off roller 1111 are adjusted to keep the force on the diamond wire on the pay-off roller 1111 and the reversing wheel 1114 in dynamic balance, thereby improving the tension difference caused by factors such as the oblique pulling of the diamond wire.

[0152] Step S32101: Control the motor speed of the wire feeding roller according to the wire feeding speed value so that the cutting line and the main shaft of the wire feeding roller tend to be perpendicular.

[0153] The electric control system 12 controls the motor speed of the wire feeding roller to decrease, thereby reducing the motor rotation frequency of the wire feeding roller 1111 and slowing down the moving speed of the wire feeding roller 1111. This keeps the force of the diamond wire on the wire feeding roller 1111 in a dynamic balance state, so that the diamond wire tends to be perpendicular to the main axis of the wire feeding roller 1111.

[0154] In some embodiments, step S3210 may specifically include steps S32100-S32130:

[0155] Step S32100: When the reversing wheel is tilted in the first direction relative to the reference state, the second included angle is greater than the second preset included angle threshold, and the wire feeding roller moves in the first direction, it is determined that the wire feeding speed value of the wire feeding roller is less than zero.

[0156] The first direction is defined as tilting to the right, and the second direction is tilting to the left. When the reversing wheel 1114 is tilted to the right relative to the reference state, and a > a0, and the pay-off roller 1111 is in the direction of movement from left to right, the wire feeding speed of the pay-off roller 1111 should be reduced to slow down the movement speed of the pay-off roller 1111. This will maintain a dynamic balance between the forces on the diamond wire on the pay-off roller 1111 and the reversing wheel 1114, thereby making the diamond wire tend to be perpendicular to the main shaft of the pay-off roller 1111 or the main shaft of the reversing wheel 1114.

[0157] Step S32110: When the reversing wheel is tilted in the second direction relative to the reference state, the second included angle is greater than the second preset included angle threshold, and the wire feeding roller moves in the first direction, determine that the wire feeding speed value of the wire feeding roller is greater than zero.

[0158] When the reversing wheel 1114 is tilted to the left relative to the reference state, and a > a0, and the pay-off roller 1111 is in the direction of movement from left to right, the wire feeding speed of the pay-off roller 1111 should be increased to speed up the movement of the pay-off roller 1111. This will keep the forces on the diamond wire on the pay-off roller 1111 and the reversing wheel 1114 in a dynamic balance, so that the diamond wire tends to be perpendicular to the main shaft of the pay-off roller 1111 or the main shaft of the reversing wheel 1114.

[0159] Step S32120: When the reversing wheel is tilted in the first direction relative to the reference state, the second included angle is greater than the second preset included angle threshold, and the wire feeding roller moves in the second direction, determine that the wire feeding speed value of the wire feeding roller is greater than zero.

[0160] When the reversing wheel 1114 is tilted to the right relative to the reference state, and a > a0, and the pay-off roller 1111 is in the direction of movement from right to left, the wire feeding speed of the pay-off roller 1111 should be increased to speed up the movement of the pay-off roller 1111. This will keep the forces on the diamond wire on the pay-off roller 1111 and the reversing wheel 1114 in a dynamic balance, so that the diamond wire tends to be perpendicular to the main shaft of the pay-off roller 1111 or the main shaft of the reversing wheel 1114.

[0161] Step S32130: When the reversing wheel is tilted in the second direction relative to the reference state, the second included angle is greater than the second preset included angle threshold, and the wire feeding roller moves in the second direction, it is determined that the wire feeding speed value of the wire feeding roller is less than zero.

[0162] When the reversing wheel 1114 is tilted to the left relative to the reference state and a > a0, and the pay-off roller 1111 is in the direction of movement from right to left, the wire feeding speed of the pay-off roller 1111 should be reduced to slow down the movement speed of the pay-off roller 1111. This will keep the forces on the diamond wire on the pay-off roller 1111 and the reversing wheel 1114 in a dynamic balance, so that the diamond wire is perpendicular to the main shaft of the pay-off roller 1111 or the main shaft of the reversing wheel 1114.

[0163] In the above steps, by determining the relationship between the second included angle and the second preset included angle threshold, and the moving direction of the wire feeding roller 1111 when feeding the wire, the wire feeding speed value of the wire feeding roller 1111 is quickly and accurately determined, so that the force of the diamond wire on the wire feeding roller 1111 and the reversing wheel 1114 is kept in a dynamic balance state.

[0164] In some embodiments, please refer to Figure 8 As shown, step S310 may specifically include: steps S311-S312:

[0165] Step S311: Obtain the electrical signal generated when the cutting line detection device 13 contacts the cutting line within the detection area 131.

[0166] Step S312: Determine the tilt direction of the cutting line relative to the reference state based on the electrical signal.

[0167] The cutting wire detection device 13 has a detection area 131. The diamond wire must pass through the detection area 131 to ensure that the diamond wire can be detected by the cutting wire detection device 13. The detection principle of the cutting wire detection device 13 is that the sensing component provided on the cutting wire detection device 13 senses or contacts the diamond wire to form an energized loop, thereby generating an electrical signal. The electronic control system 12 determines the tilt direction of the diamond wire relative to a reference state based on the generated electrical signal.

[0168] In the above embodiments, the diamond wire during the wire running process is detected by the cutting wire detection device 13. Based on the electrical signal generated after the diamond wire is sensed by the cutting wire detection device 13, the direction of the diamond wire tilt can be accurately and quickly determined.

[0169] In some embodiments, the wire cutting detection device 13 includes a first sensor 132, a second sensor 133, and a drive unit 134; the drive unit 134 is connected to the first sensor 132 and the second sensor 133. The first sensor 132 and the second sensor 133 can be mounted on the drive unit 134 via a bracket 135. The bracket 135 can be supported by an insulating material to effectively isolate the interference of the sensors generating electrical signals when they contact the diamond wire to the drive unit 134.

[0170] The first sensing element 132 is defined as being located to the left of the diamond wire in the reference state, and the second sensing element 133 is defined as being located to the right of the diamond wire in the reference state.

[0171] In some embodiments, the first sensing element 132 and the second sensing element 133 are both made of conductive material. For example, the first sensing element 132 and the second sensing element 133 can be set as copper rods.

[0172] Furthermore, step S311 may specifically include: steps S3111-S3112:

[0173] Step S3111: Control drive unit 134 drives first sensor 132 and second sensor 133 from open state to closed state.

[0174] The drive unit 134 can be electrically connected to the electronic control system 12. The electronic control system 12 sends control commands to the drive unit 134. The drive unit 134 receives the commands and drives the first sensor 132 and the second sensor 133 to form an open or closed state.

[0175] In some embodiments, the drive unit 134 is one of a parallel opening and closing type pneumatic gripper, a cylinder, a hydraulic cylinder, an electric push rod, or a lead screw motor. In this embodiment, the drive unit 134 is exemplified by a parallel opening and closing type pneumatic gripper. The parallel opening and closing type pneumatic gripper can improve the problem of tilting of the first sensor 132 and the second sensor 133 during the opening and closing action, and can perform opening and closing operations as needed, realizing fast and precise opening and closing actions and improving work efficiency.

[0176] Step S3112: Acquire the electrical signal generated when the first sensor 132 and the second sensor 133 come into contact with the cutting line in the detection area 131 during the closing process.

[0177] The opening and closing action is achieved by driving the first sensor 132 and the second sensor 133 to move closer or further apart through the drive unit 134. A diamond wire passes through the detection area 131 between the first sensor 132 and the second sensor 133. During the process of the drive unit 134 driving the first sensor 132 and the second sensor 133 from the open state to the closed state, an electrical loop is formed when the diamond wire contacts either the first sensor 132 or the second sensor 133, emitting an electrical signal.

[0178] In another embodiment, a processing component 136 can be provided in the cutting wire detection device 13. The processing component 136 is electrically connected to the first sensor 132 and the second sensor 133 to receive the electrical signal and control the cutting wire detection device 13 to move and correct the diamond wire.

[0179] As an example, the processing unit 136 may include a processor and a memory connected via a bus. The memory stores instructions that can be executed by the processor, which then executes the instructions to cause the cutting line detection device 13 to perform all or part of the correction process.

[0180] Optionally, the processing unit 136 and the electronic control system 12 can be independent control modules, or the processing unit 136 and the electronic control system 12 can be integrated together.

[0181] In the above embodiment, the opening and closing action is achieved by driving the first sensor 132 and the second sensor 133 through the driving unit 134. During the closing process of the first sensor 132 and the second sensor 133, the tilt direction of the diamond wire can be quickly determined by using the electrical signal generated when either of the sensors comes into contact with the diamond wire. This method of detecting diamond wire is simpler and faster.

[0182] Furthermore, step S312 may specifically include steps S3121-S3122:

[0183] Step S3121: When the electrical signal generated by the first sensing element 132 contacting the cutting line is obtained, it is determined that the cutting line is tilted to the left relative to the reference state.

[0184] Please refer to Figure 9 As shown in Figures 10(a), 10(b), and 10(c), the electronic control system 12 sends a control command to the drive unit 134. The drive unit 134 receives the control command and begins to work. When the drive unit 134 drives the first sensor 132 and the second sensor 133 to move towards each other (as shown in Figure 10(a)), during the process from the open state to the closed state, the conductive first sensor 132 is the first to contact the diamond wire to form a current-carrying loop and generate an electrical signal (as shown in Figure 10(b)). Based on the fact that the first sensor 132 is the first to generate an electrical signal upon contact with the diamond wire, it can be determined that the direction of the first sensor 132 that triggers the electrical signal is the tilt direction of the diamond wire, that is, the diamond wire is tilted to the left relative to the reference state. After the first sensing element 132 comes into contact with the electrical signal generated by the diamond wire, the driving unit 134 continues to drive the first sensing element 132 and the second sensing element 133 to continue moving until the first sensing element 132 and the second sensing element 133 are completely closed. In the gap between the first sensing element 132 and the second sensing element 133, the diamond wire is still in contact with the first sensing element 132 (as shown in Figure 10(c)).

[0185] It should be noted that after the first sensing element 132 and the second sensing element 133 are fully closed, there is a gap between them. This allows the diamond wire to move between the first sensing element 132 and the second sensing element 133, so that it is not clamped and contacted by the first sensing element 132 and the second sensing element 133 and generates an electrical signal, which would affect the accuracy of the detection and correction results of the cutting wire detection device 13.

[0186] Step S3122: When the electrical signal generated by the second sensing element 133 contacting the cutting line is obtained, it is determined that the cutting line is tilted to the right relative to the reference state.

[0187] Please refer to Figure 11As shown in Figures 12(a), 12(b), and 12(c), the electronic control system 12 sends a control command to the drive unit 134. The drive unit 134 receives the control command and begins to work. When the drive unit 134 drives the first sensor 132 and the second sensor 133 to move towards each other (as shown in Figure 12(a)), during the process from the open state to the closed state, the conductive second sensor 133 is the first to contact the diamond wire to form a current-carrying loop and generate an electrical signal (as shown in Figure 12(b)). Based on the fact that the second sensor 133 is the first to generate an electrical signal upon contact with the diamond wire, it can be determined that the direction of the second sensor 133 that triggers the electrical signal is the tilt direction of the diamond wire, that is, the diamond wire is tilted to the left relative to the reference state. After the second sensor 133 comes into contact with the electrical signal generated by the diamond wire, the driving unit 134 continues to drive the second sensor 133 to continue moving until the first sensor 132 and the second sensor 133 are completely closed. In the gap between the first sensor 132 and the second sensor 133, the diamond wire is still in contact with the second sensor 133 (as shown in Figure 12(c)).

[0188] Based on the position of the sensing element that triggers the electrical signal, the current tilt direction of the diamond wire can be quickly and accurately determined. After determining whether the diamond wire is tilted to the left or right relative to the reference state, the diamond wire can be further corrected using the cutting wire detection device 13. The diamond wire can be moved by moving the cutting wire detection device 13, thereby correcting the diamond wire's tilt.

[0189] In some embodiments, the cutting wire detection device 13 may further include a moving component 137. The moving component 137 is electrically connected to the drive unit 134. After receiving an electrical signal generated by the first sensor 132 or the second sensor 133, the processing unit 136 controls the moving component 137 to move according to the electrical signal, so that the cutting wire detection device 13 moves, so that the diamond wire tends to be perpendicular to the main shaft of the wire feeding roller 1111 or the wire feeding wheel 1112.

[0190] The moving part 137 can be the linear drive module described above, which is mounted on the wire feeding roller bracket. The drive unit 134 can be fixed to the linear drive module. In some embodiments, the linear drive module can drive the wire cutting detection device 13 to reciprocate in the spindle direction of the wire feeding roller 1111 or the wire feeding roller 1112.

[0191] In the above embodiments, the current tilt direction of the diamond wire can be quickly determined based on the position of the sensor that triggers the electrical signal. Based on the tilt direction of the diamond wire, the moving component 137 is controlled to move, causing the diamond wire to move in the direction of the sensor that generates the electrical signal. This corrects the diamond wire's deviation, reducing the probability of tilting during the wire running process and thus improving the cutting efficiency of the diamond wire.

[0192] Furthermore, after step S312, the method also includes steps S3123-S314:

[0193] Step S313: When the electrical signal generated by the first sensor 132 contacting the cutting line is obtained, the moving part 137 is controlled to move in the direction of the first sensor 132 so that the cutting line is between the first sensor 132 and the second sensor 133.

[0194] exist Figure 9 In Figures 10(a), 10(b), and 10(c), during the process of the drive unit 134 driving the first sensor 132 and the second sensor 133 from the open state to the closed state, the first sensor 132 first contacts the diamond wire and forms an energized loop, emitting an electrical signal. After receiving the electrical signal, the processing unit 136 sends a control command to the moving unit 137. After receiving the command, the moving unit starts to drive the drive unit 134 and the first sensor 132 and the second sensor 133 to move together, so that the cutting wire detection device 13 moves. During the movement of the cutting wire detection device 13, the diamond wire in contact with one of the sensors moves along with it until the diamond wire tends to be perpendicular to the main shaft of the wire feeding roller 1111 or the wire feeding wheel 1112. At this time, the electrical signal disappears. According to the signal that the electrical signal disappears, the processing unit 136 controls the moving unit 137 to stop working, and the cutting wire detection device 13 stops moving (as shown in Figure 10(d)).

[0195] In some embodiments, the drive unit 134 and the wire guide roller 1112 can be simultaneously mounted on the moving member 137. Therefore, the moving member 137 can simultaneously drive the drive unit 134, the first sensor 132, the second sensor 133, and the wire guide roller 1112 to move together. When the moving member 137 drives the cutting wire detection device 13 and the wire guide roller 1112 to move together, the diamond wire gradually becomes perpendicular to the main shaft of the winding pay-off roller 1111. When the diamond wire loses contact with the first sensor 132, the electrical signal disappears, and the processing member 136 does not receive an electrical signal, indicating that the diamond wire has been corrected and is becoming perpendicular to the main shaft of the pay-off roller 1111.

[0196] Step S314: When the electrical signal generated by the second sensor 133 contacting the cutting line is obtained, the moving part is controlled to move in the direction of the second sensor 133 so that the cutting line is between the first sensor 132 and the second sensor 133.

[0197] Similarly, in Figure 11In Figures 12(a), 12(b), and 12(c), during the process of the drive unit 134 driving the first sensor 132 and the second sensor 133 from the open state to the closed state, the second sensor 133 first contacts the diamond wire and forms an energized loop, emitting an electrical signal. After receiving the electrical signal, the processing unit 136 sends a control command to the moving unit 137. After receiving the command, the moving unit starts to drive the drive unit 134 and the first sensor 132 and the second sensor 133 to move together, so that the cutting wire detection device 13 moves. During the movement of the cutting wire detection device 13, the diamond wire in contact with one of the sensors moves along with it until the diamond wire tends to be perpendicular to the main shaft of the wire feeding roller 1111 or the wire feeding wheel 1112. At this time, the electrical signal disappears. According to the signal that the electrical signal disappears, the processing unit 136 controls the moving unit 137 to stop working, and the cutting wire detection device 13 stops moving (as shown in Figure 12(d)).
