Description

Technical Field

[0001] This application relates to the technical field of hard material cutting. Specifically, it relates to a deviation rectifying device and a cutting device. Background Art

[0002] A photovoltaic wire saw slicing machine is a special device that relies on a wire saw as a cutting tool to cut a single crystal silicon rod into silicon wafers with a specific thickness. In the fields of photovoltaic crystalline silicon and semiconductor cutting, photovoltaic wire saw slicing machines with single-wire or multi-wire saws are often used to truncate, square, and slice silicon materials, etc., in order to obtain corresponding silicon wafers or silicon materials.

[0003] During the cutting process of a photovoltaic wire saw slicing machine, the wire saw is paid out from a pay-off reel, and runs towards the take-up area through the guiding of a wire arranging wheel and the guiding of a tension wheel. The actual wire arranging pitch of the wire saw on the pay-off reel should be the same as the theoretical wire arranging pitch of the cutting system. However, due to the precision error of mechanical equipment, etc., there is always a deviation between the actual wire arranging pitch and the theoretical wire arranging pitch, which further leads to the asynchronous wire arranging positions of the pay-off reel and the wire arranging wheel during the actual slicing process. This deviation will gradually accumulate as the wire saw continuously cuts, causing the wire saw to tilt, so that there is an angle between the wire saw and the pay-off reel and they are not perpendicular. Summary of the Utility Model

[0004] The purpose of the embodiments of this application is to provide a deviation rectifying device and a cutting device, which improve the problem of the cutting wire being obliquely pulled or tilted during the running process, reduce the probability of the cutting wire breaking, and improve the cutting efficiency of the cutting wire and the quality of the cut products.

[0005] In a first aspect, this application provides a deviation rectifying device, including: a sensing part, a cutting wire is wound around a wire wheel and can pass through the sensing part; a driving part, the driving part is connected to the sensing part, the driving part is used to drive the sensing part from an open state to a closed state, and the sensing part is used to generate an electrical signal when it comes into contact with the cutting wire; a moving component, connected to the driving part; a processing component, electrically connected to the sensing part, and used to receive the electrical signal and control the movement of the moving component according to the electrical signal so that the sensing part is separated from the cutting wire.

[0006] During the continuous cutting process of the cutting line, due to the gradual accumulation of the deviation between the actual wire arrangement pitch of the cutting line on the wire wheel and the theoretical wire arrangement pitch of the cutting system, the cutting line tilts, resulting in an angle between the cutting line and the wire wheel instead of being perpendicular. As the deviation angle accumulates and gradually expands, when it reaches a certain value, it causes the cutting line to touch the edge of the wire wheel. Irregular stacking occurs at the edge of the wire wheel, leading to layer misalignment and wire pressing, or the cutting line rubs against the edge of the wire wheel, resulting in wire breakage. After a certain deviation angle has accumulated between the cutting line and the wire wheel, the cutting line is introduced into the main roller groove. The cutting line entering the main roller groove is no longer perpendicular to the main roller groove. Instead, it has a tendency to move towards the bottom of the groove. At this time, the force exerted by the cutting line on the main roller groove can be decomposed into a component force perpendicular to the bottom of the groove and a component force along the inclined direction of the groove. These two component forces act on the main roller groove, causing the cutting line to twist in the groove, thereby increasing the probability of wire breakage of the cutting line.

[0007] In order to solve the above technical problems, in the above technical solution, a deviation rectifying device is used to detect the cutting line during the wire running process, so as to judge the position and direction of the cutting line being pulled obliquely or tilted. The deviation between the wire arrangement pitch of the cutting line on the wire wheel and the theoretical wire arrangement pitch of the cutting system is corrected in a timely manner by the deviation rectifying device, reducing the probability of the cutting line being pulled obliquely or tilted during the wire running process. Further, the probability of wire breakage of the cutting line can be reduced, improving the cutting efficiency of the cutting line and the quality of the cut products.

[0008] In one embodiment, the sensing part includes: a bracket and a sensing component. The driving part is connected to the bracket, and the sensing component is arranged on the bracket.

[0009] In the above technical solution, by connecting the driving part and the sensing component through a bracket, the interference effect of the sensing component on the driving part when generating an electrical signal in contact with the cutting line can be effectively isolated.

[0010] In one embodiment, the sensing component includes: a first sensing element and a second sensing element. A detection area is formed between the first sensing element and the second sensing element, and the cutting line passes through the detection area. When the cutting line touches the first sensing element or the second sensing element, the electrical signal is generated.

[0011] In the above technical solution, by setting two sensing elements to jointly form an open or closed state, during the process from the open state to the closed state between the first sensing element and the second sensing element, according to the electrical signal generated when the cutting line first touches one of the sensing elements, the tilting direction of the cutting line on the wire wheel can be quickly, intuitively, and accurately judged, which is the direction of the sensing element in contact with the cutting line.

[0012] In one embodiment, when the first sensing member and the second sensing member are in the closed state, there is a gap between the first sensing member and the second sensing member.

[0013] In the above technical solution, by leaving a gap between the first sensing member and the second sensing member after complete closure, it can reserve a space for the cutting wire to move in the gap, and the cutting wire will not be clamped and contacted by the first sensing member and the second sensing member to generate an electrical signal, which affects the detection of the deviation correction device and the accuracy of the deviation correction result. At the same time, the gap between the first sensing member and the second sensing member enables the cutting wire to continuously pass through the detection area.

[0014] In one embodiment, the deviation correction device further includes: a warning member, and the warning member is electrically connected to the first sensing member and the second sensing member respectively.

[0015] In the above technical solution, by setting the warning member, it can quickly and intuitively feedback the state of the electrical signal generated after the first sensing member or the second sensing member contacts the cutting wire, which helps to quickly judge the inclination direction of the cutting wire.

[0016] In one embodiment, the driving part is one of a parallel opening and closing type air gripper, a cylinder, an oil cylinder, an electric push rod, and a lead screw motor.

The electric control system is further used to control the movement of the wire wheel around which the cutting wire is wound according to the electrical signal, so that the cutting wire tends to be perpendicular to the main shaft of the wire wheel.

[0018] In the above technical solution, by arranging a deviation correction device in the cutting system and using the deviation correction device to detect the cutting wire during the wire running process, the position and direction of the cutting wire being obliquely pulled or inclined can be judged. According to the inclination direction of the cutting wire, the position state of the cutting wire is adjusted by adjusting the position of the deviation correction device, and the deviation between the wire arrangement pitch of the cutting wire on the wire wheel and the theoretical wire arrangement pitch of the cutting system is corrected in time, improving the problem of the cutting wire being obliquely pulled or inclined during the wire running process, reducing the probability of the cutting wire breaking, and improving the cutting efficiency of the cutting wire and the quality of the cut product.

[0019] In one embodiment, the electric control system is further configured to control the movement of the wire wheel around which the cutting wire is wound according to the electric signal, so that the cutting wire tends to be perpendicular to the main shaft of the wire wheel.

[0020] In the above technical solution, the movement of the wire wheel around which the cutting wire is wound is adjusted by the electric control system, so that the cutting wire can finally be perpendicular to the main shaft of the wire wheel, timely correcting the deviation between the wire arrangement pitch of the cutting wire on the wire wheel and the theoretical wire arrangement pitch of the cutting system, improving the problems of diagonal pulling or inclination of the cutting wire during the wire running process, reducing the probability of the cutting wire breaking, and improving the cutting efficiency of the cutting wire and the quality of the cut product.

At the same time, the cutting wire that is diagonally pulled or inclined during the wire running and cutting process on the main roller can be timely corrected to reduce the probability of the cutting wire breaking and improve the cutting efficiency of the cutting wire and the quality of the cut product.

Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0044] Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0045] Please refer to Figure 1 , the present application provides a cutting equipment 1, and the cutting equipment 1 may include: a cutting system 12 and an electric control system 13; the electric control system 13 is electrically connected to the cutting system 12.

[0046] The electric control system 13 is used to control the cutting system 12 to cut hard materials through a cutting line, and the hard materials may be photovoltaic silicon rods, crystalline silicon, semiconductors, gems, magnetic materials, etc.

[0047] Further, the cutting system 12 includes: a wire pay-off area 121, a cutting area 122, and a wire take-up area 123. Among them, the wire pay-off area 121 includes: a wire pay-off roller 1211, a wire arranging wheel 1212, and a tension wheel 1213. The wire pay-off roller 1211 is a wire wheel for winding the cutting wire and is driven to rotate by a motor. The wire arranging wheel 1212 is a wire wheel for guiding the cutting wire. The wire arranging wheel 1212 can be driven by a linear drive module to perform a linear reciprocating motion in the main axis direction of the wire pay-off roller 1211 to guide the cutting wire to the cutting position, and has multiple functions such as transmitting force, reducing frictional resistance, and solving problems of too tight or too loose fitting accuracy. The linear drive module can be fixedly installed on the wire arranging wheel bracket. In some embodiments, the linear drive module can be one of a lead screw motor and a slider assembly, a linear motor module, a gear and rack transmission assembly, etc. The tension wheel 1213 is a wire wheel for adjusting the tension of the cutting wire on the wire arranging wheel 1212. Usually, the number of tension wheels 1213 ≥ 1.

[0048] The cutting wire is wound between the wire pay-off roller 1211, the wire arranging wheel 1212, and the tension wheel 1213. Specifically, the cutting wire is wound on the wire pay-off roller 1211 and then wound to the upper wire arranging wheel 1212. The wire arranging wheel 1212 is installed between the wire pay-off roller 1211 and the tension wheel 1213 and is used to wind the cutting wire on the wire pay-off roller 1211 with a certain pitch. The cutting wire is guided and wound around the tension wheel 1213 after being guided by the wire arranging wheel 1212, and is guided to the cutting area 122 through several tension wheels 1213.

[0049] The cutting area 122 includes: at least one main roller 1221 and a first guide wheel 1222; the cutting wire guided by the tension wheel 1213 is introduced into the main roller 1221 by the first guide wheel 1222 and is wound between the main rollers 1221. The main roller 1221 is a wire wheel for winding the cutting wire to form a cutting wire mesh 1223. Usually, the number of main rollers 1221 ≥ 2. The first guide wheel 1222 is a wire wheel for guiding the cutting wire to the main roller 1221. The cutting wire is adjusted, transmitted, and guided from the wire pay-off area 121 through the wire pay-off roller 1211, the wire arranging wheel 1212, and multiple tension wheels 1213 to the first guide wheel 1222, and then is guided by the first guide wheel 1222 to the main roller 1221 and is repeatedly wound around two parallel main rollers 1221 for multiple turns.

[0050] To prevent the cutting wire from running off when winding around the main roller 1221, usually, multiple grooves for accommodating the cutting wire can be provided on the main roller 1221 to limit the position of the cutting wire. After rewinding the wire, a cutting wire mesh 1223 for cutting is formed on the two main rollers 1221, and the end cutting wire after winding on the main roller 1221 then passes through the wire take-up area 123.

[0051] The wire winding area 123 includes: a second guide pulley 1231 and a wire winding roller 1232. The cutting wire wound around the main rollers 1221 is introduced into the wire winding roller 1232 through the second guide pulley 1231. The second guide pulley 1231 is a wire pulley for guiding the cutting wire to the wire winding roller 1232. The wire winding roller is a wire pulley for winding the used cutting wire.

[0052] In some embodiments, at least one idler pulley 1233 is further provided between the second guide pulley 1231 and the wire winding roller 1232. The idler pulley 1233 is arranged between the second guide pulley 1231 and the wire winding roller 1232 and is used to change the direction of the cutting wire so that the cutting wire can be smoothly wound onto the wire winding roller 1232. Generally, the number of idler pulleys 1233 ≥ 1. The cutting wire wound around the main roller 1221 is introduced into the idler pulley 1233 through the second guide pulley 1231 and is introduced into the wire winding roller 1232 by the idler pulley 1233.

[0053] In the cutting system 12 of this embodiment, the cutting wire is respectively wound around the wire feeding roller 1211, the wire arranging wheel 1212, and the tension wheel 1213, is introduced into the main roller 1222 through the first guide pulley 1222, is wound around the main roller 1221 for multiple turns to form a cutting wire net 1223, then is introduced into the idler pulley 1233 through the second guide pulley 1231, and finally is introduced into the wire winding roller 1232 through the idler pulley 1233. The wire winding roller 1232 recovers the cut cutting wire.

[0054] Exemplarily, the cutting wire is a diamond wire, a high-carbon steel wire, etc. In this embodiment, the diamond wire is taken as an example. According to the cutting principle of the diamond wire, the electric control system 13 controls the cutting system 12 to perform periodic reciprocating wire feeding in sequence from the wire feeding area 121 to the cutting area 122 and then to the wire winding area 123. When the diamond wires on all the wire wheels in the cutting system 12 are running at high speed, by controlling the hard material to be cut to be lowered to the cutting wire net 1223, under the action of applying pressure to the hard material, the diamond wire is pressed into the bottom surface of the hard material to cut the hard material into slices.

[0055] During the cutting process of the hard material, the new diamond wire on the wire feeding roller 1211 is gradually released to the wire winding roller 1232. The specific periodic reciprocating wire running mode is as follows:

[0056] In the first-cycle wire feeding stage, the wire feeding is controlled to proceed in sequence from the wire feeding area 121 to the cutting area 122 and then to the wire take-up area 123. Specifically, the running direction of the diamond wire is as follows: wire feeding roller 1211 → wire arranging wheel 1212 → tension wheel 1213 → first guide wheel 1222 → main roller 1221 → second guide wheel 1231 → idler wheel 1233 → wire take-up roller 1232. During the first-cycle wire feeding process, the wire speed of the diamond wire is controlled to accelerate from the first speed to the second constant speed and then decelerate from the second constant speed to the third speed to achieve the cutting of hard materials. Define the first speed V1 = 0, the second constant speed as V2, and the third speed as V3. Therefore, the change in the wire speed of the diamond wire is as follows: from the initial first speed V1 = 0 → one-way acceleration (gradually accelerating from the wire feeding area 121 towards the wire take-up area 123) → running at a constant speed with the second speed V2 → one-way deceleration to the third speed V3 (gradually decelerating from the wire feeding area 121 towards the wire take-up area 123).

[0057] In the first-cycle wire retracting stage, the wire retracting is controlled to proceed in sequence from the wire take-up area 123 to the cutting area 122 and then to the wire feeding area 121. Specifically, the running direction of the diamond wire is as follows: wire take-up roller 1232 → idler wheel 1233 → second guide wheel 1231 → main roller 1221 → first guide wheel 1222 → tension wheel 1213 → wire arranging wheel 1212 → wire feeding roller 1211. During the first-cycle wire retracting process, the wire speed of the diamond wire is controlled to accelerate from the first speed to the second constant speed and then decelerate from the second constant speed to the third speed to achieve the cutting of hard materials. In the first-cycle wire retracting stage, the first speed V1, the second constant speed V2, and the third speed V3 adopt the same speeds as those corresponding to the first-cycle wire feeding stage. Therefore, the change in the wire speed of the diamond wire is as follows: from the initial first speed V1 = 0 → one-way acceleration (gradually accelerating from the wire take-up area 123 towards the wire feeding area 121) → running at a constant speed with the second speed V2 → one-way deceleration to the third speed V3 (gradually decelerating from the wire take-up area 123 towards the wire feeding area 121).

[0058] In the second-cycle wire feeding stage, the wire feeding is controlled to proceed in sequence from the wire feeding area 121 to the cutting area 122 and then to the wire take-up area 123. Specifically, the running direction of the diamond wire is as follows: wire feeding roller 1211 → wire arranging wheel 1212 → tension wheel 1213 → first guide wheel 1222 → main roller 1221 → second guide wheel 1231 → idler wheel 1233 → wire take-up roller 1232. During the second-cycle wire feeding process, the wire speed of the diamond wire is controlled to accelerate from the first speed to the second constant speed and then decelerate from the second constant speed to the third speed to achieve the cutting of hard materials. Similarly, the first speed V1 = 0, the second constant speed is V2, and the third speed is V3. Therefore, the change in the wire speed of the diamond wire is as follows: from the initial first speed V1 = 0 → one-way acceleration (gradually accelerating from the wire feeding area 121 towards the wire take-up area 123) → running at a constant speed with the second speed V2 → one-way deceleration to the third speed V3 (gradually decelerating from the wire feeding area 121 towards the wire take-up area 123).

[0059] In the second cycle return line stage, the wire pay-off in the pay-off area 123, the cutting area 122, and the wire feeding area 121 is controlled to be carried out in sequence. Specifically, the running direction of the diamond wire is as follows: pay-off roller 1232 → idler pulley 1233 → second guide pulley 1231 → main roller 1221 → first guide pulley 1222 → tension pulley 1213 → wire arranging pulley 1212 → wire feeding roller 1211. During the second cycle return line process, the wire speed of the diamond wire is controlled to accelerate from the first speed to the second constant speed, and then decelerate from the second constant speed to the third speed to achieve the cutting of hard materials. Similarly, the first speed V1 = 0, the second constant speed is V2, and the third speed is V3. Therefore, the change in the wire speed of the diamond wire is as follows: from the initial first speed V1 = 0 → one-way acceleration (gradually accelerating from the pay-off area 123 to the wire feeding area 121) → running at a constant speed with the second speed V2 → third speed V3 one-way deceleration (gradually decelerating from the pay-off area 123 to the wire feeding area 121).

[0060] Continue the above running line process until the cutting of the hard material is completed.

[0061] During the periodic reciprocating running line process, due to a certain deviation between the actual wire arranging pitch of the diamond wire on the wire feeding roller and the theoretical wire arranging pitch of the cutting system, this deviation will gradually accumulate and increase during the process of the diamond wire continuously running for cutting, causing the diamond wire to tilt more severely. As the error accumulation gradually increases, the probability of the diamond wire breaking will also gradually increase, ultimately affecting the cutting efficiency of the diamond wire and the quality of the cut product. In addition, when the diamond wire in the cutting wire mesh is not perpendicular to the main roller, it is easy for the diamond wire to twist in the groove of the main roller, which also increases the probability of the diamond wire breaking and affects the cutting efficiency and the quality of the cut product.

[0062] Therefore, in order to reduce the risk of wire breakage during the running line process of the diamond wire, improve the cutting efficiency of the diamond wire, and the quality of the cut product, a deviation rectifying device 11 is also provided in the cutting device 1 of the present application. The deviation rectifying device 11 is arranged in the cutting system 12, and the electric control system 13 is electrically connected to the deviation rectifying device 11.

[0063] The electric control system 13 is further used to control the deviation rectifying device 11 to detect the cutting wire. The deviation rectifying device 11 is used to generate an electric signal when detecting the cutting wire and control the movement of the deviation rectifying device 11 according to the electric signal, so that the cutting wire tends to be perpendicular to the main shaft of the wire wheel; at the same time, the electric control system 13 controls the movement of the wire wheel around which the cutting wire is wound according to the electric signal triggered by the deviation rectifying device 11, so that the cutting wire tends to be perpendicular to the main shaft of the wire wheel, realizing the correction of the inclination of the cutting wire.

[0064] In this embodiment, by providing a deviation rectifying device 11 in the cutting system 12, the deviation rectifying device 11 is used to detect the wire saw during the wire running process, so as to judge the position and direction where the wire saw is obliquely pulled or tilted. According to the tilting direction of the wire saw, the position of the wire saw is adjusted by adjusting the position of the deviation rectifying device 11. At the same time, relying on the electric control system 13 to move and adjust the wire wheels around which the wire saw is wound, finally enabling the wire saw to tend to be perpendicular to the main shaft of the wire wheel, thereby timely correcting the deviation between the wire arrangement pitch of the wire saw on the wire wheel and the theoretical wire arrangement pitch of the cutting system 12, reducing the probability of the wire saw being obliquely pulled or tilted during the wire running process, and further being able to reduce the probability of the wire saw breaking, thereby improving the cutting efficiency of the wire saw and the quality of the cut product.

[0065] Please refer to Figure 1 As shown, the deviation rectifying device 11 is provided on the periphery of the cutting wire in at least one of the wire paying-off area 121, the cutting area 122, and the wire taking-up area 123.

[0066] In some embodiments, the deviation rectifying device 11 is movably provided between the wire paying-off roller 1211 and the wire arranging wheel 1212, and the cutting wire can pass through the sensing part of the deviation rectifying device 11. In this embodiment, an installation bracket can be provided between the wire paying-off roller 1211 and the wire arranging wheel 1212, and the deviation rectifying device 11 can be fixed on the installation bracket.

[0067] In this embodiment, the deviation rectifying device 11 is provided between the wire paying-off roller 1211 and the wire arranging wheel 1212, and the cutting wire can pass through the sensing part of the deviation rectifying device 11, which can timely rectify the deviation between the wire arrangement pitch of the wire saw on the wire paying-off roller 1211 and the theoretical wire arrangement pitch of the cutting system 12 at the initial stage of the wire running of the wire saw, improve the problem of the wire saw being obliquely pulled or tilted during the wire running process, and further reduce the deviation accumulation in the subsequent wire running process.

[0068] In some other embodiments, the deviation rectifying device 11 is movably provided between the first guide wheel 1222 and the main roller 1221, and the cutting wire can pass through the sensing part of the deviation rectifying device 11. In this embodiment, an installation bracket can be provided between the first guide wheel 1222 and the main roller 1221, and the deviation rectifying device 11 can be fixed on the installation bracket.

[0069] In this embodiment, the deviation rectifying device 11 is provided between the first guide wheel 1222 and the main roller 1221, and the wire saw can pass through the sensing part of the deviation rectifying device 11, which can make the wire saw that first enters the main roller 1221 perpendicular to the groove of the main roller 1221, improve the situation of the wire saw twisting in the groove of the main roller 1221, thereby reducing the probability of the wire saw breaking, and further improving the cutting efficiency and cutting quality.

[0070] In some other embodiments, the deviation rectifying device 11 is movably disposed between the main roller 1221 and the second guiding wheel 1231, and the diamond wire can pass through the sensing portion of the deviation rectifying device 11. In this embodiment, a mounting bracket can be provided between the main roller 1221 and the second guiding wheel 1231, and the deviation rectifying device 11 can be fixed on the mounting bracket.

[0071] Similarly, in this embodiment, the deviation rectifying device 11 is disposed between the main roller 1221 and the second guiding wheel 1231, and the diamond wire can pass through the sensing portion of the deviation rectifying device 11, which can keep the diamond wire in the main roller 1221 perpendicular to the groove of the main roller 1221, improve the situation that the diamond wire twists in the groove of the main roller 1221, thereby reducing the probability of diamond wire breakage and further improving the cutting efficiency and cutting quality.

[0072] In order to reduce the error accumulation between the actual wire arrangement pitch of the diamond wire on the wire pay-off roller 1211 and the theoretical wire arrangement pitch of the cutting system in the initial stage of wire running, and at the same time, improve the situation that the diamond wire twists in the groove of the main roller 1221, in the embodiments of the present application, the deviation rectifying device 11 can be simultaneously disposed on the circumferential side of the diamond wire between the wire pay-off roller 1211 and the wire arranging wheel 1212, on the circumferential side of the diamond wire between the first guiding wheel 1222 and the main roller 1221, and on the circumferential side of the diamond wire between the main roller 1221 and the second guiding wheel 1231.

[0073] By arranging the deviation rectifying device 11 in the wire pay-off area 121, the cutting area 122, and the wire take-up area 123, it is possible to timely rectify the deviation between the wire arrangement pitch of the diamond wire on the wire pay-off roller 1211 and the theoretical wire arrangement pitch of the cutting system 12, and improve the problem of diagonal pulling or inclination of the diamond wire during wire running. At the same time, it is possible to timely rectify the diamond wire that twists during the wire running and cutting process on the main roller 1221, so as to reduce the probability of diamond wire breakage and improve the cutting efficiency of the diamond wire and the quality of the cut product.

[0074] Please refer to Figure 2 which is a schematic structural diagram of the deviation rectifying device 11 provided by an embodiment of the present application. And Figure 3 As shown, the deviation rectifying device 11 includes: a sensing portion 100, a driving portion 200, a moving member 300, and a processing portion 400. The cutting wire is wound around a wire wheel and can pass through the sensing portion 100; the driving portion 200 is connected to the sensing portion 100, and the driving portion 200 is used to drive the sensing portion 100 from an open state to a closed state, and the sensing portion 100 is used to generate an electrical signal when contacting the cutting wire. The moving member 300 is connected to the driving portion 200, and the processing portion 400 is electrically connected to the sensing portion 100, and is used to receive the electrical signal and control the movement of the moving member 300 according to the electrical signal so that the sensing portion 100 is separated from the cutting wire.

[0075] As described above, the cutting line takes the diamond wire as an example, and the wire wheels around which the diamond wire is sequentially wound include Figure 1 the unwinding roller 1211, the wire arranging wheel 1212, the tension wheel 1213, the first guiding wheel 1222, the main roller 1221, the second guiding wheel 1231, the idler wheel 1233, and the winding roller 1232 described in Figure 1 . The diamond wire passes through the detection area 103 of the induction part 100 to ensure that the induction part 100 can detect the presence of the diamond wire.

[0076] The output end of the driving part 200 is connected to the induction part 100. The driving part 200 is electrically connected to the electric control system 13. The electric control system 13 sends a control instruction to the driving part 200, and the driving part 200 receives the instruction and can drive the induction part 100 to perform an opening and closing action.

[0077] The moving part 300 can be a linear driving module arranged on the mounting bracket, and the driving part 200 can be fixed on the linear driving module. In some embodiments, the linear driving module can drive the deviation rectifying device 11 to reciprocate in the main axis direction of the wire wheel. As an example, the linear driving module can be a lead screw motor and slider assembly, a linear motor module, a gear and rack transmission assembly, a cylinder, an oil cylinder, etc.

[0078] During the process of the driving part 200 driving the induction part 100 from the open state to the closed state, when the induction part 100 contacts the diamond wire, an energized loop is formed and an electrical signal is sent out. After the processing part 400 in the deviation rectifying device 11 receives this electrical signal, it will send a control instruction to the moving part 300. After the moving part 300 receives the instruction, it starts to drive the driving part 200 and the induction part 100 to move together. During the movement, the induction part 100 gradually disengages from the diamond wire. When the induction part 100 disengages from the diamond wire and the electrical signal disappears, the processing part 400 controls the moving part 300 to stop working according to the signal of the disappearance of the electrical signal, indicating that the diamond wire tends to be vertical at this time.

[0079] In some embodiments, the driving part 200 and the wire wheel can be simultaneously arranged on the moving part 300. Therefore, the moving part 300 can simultaneously drive the driving part 200, the induction part 100, and the wire wheel to move together. During the movement, the diamond wire gradually disengages from the induction part 100 and the electrical signal disappears. After the processing part 400 does not receive the electrical signal, it indicates that the diamond wire has been corrected and tends to be perpendicular to the main axis of the wire wheel.

[0080] In some embodiments, the processing part 400 can include a processor and a memory. The processor and the memory are connected through a bus. The memory stores instructions executable by the processor. The instructions are executed by the processor to enable the deviation rectifying device 11 to execute all or part of the deviation rectifying process.

[0081] Optionally, the processing component 400 and the electronic control system 13 can be independent control modules, or the processing component 400 and the electronic control system 13 can be integrated together.

[0082] In some embodiments, the sensing unit 100 includes: a bracket 101 and a sensing assembly 102. The driving unit 200 is connected to the bracket 101, and the sensing assembly 102 is disposed on the bracket 101. In this embodiment, the bracket 101 serves as a supporting component for the sensing component 102. The output end of the driving unit 200 is connected to the bracket 101, and the sensing assembly is disposed on the bracket 101. The bracket 101 can be made of an insulating material because when the sensing assembly 102 comes into contact with the diamond wire, an electrical signal will be generated. If the sensing assembly 102 is directly connected to the driving unit 200, the electrical signal generated by the sensing assembly 102 will affect and interfere with the operation of the driving unit 200. Therefore, by providing an insulating bracket 101 between the driving unit 200 and the sensing assembly 102 for connection, the interference effect of the sensing assembly 102 on the driving unit 200 when generating an electrical signal in contact with the diamond wire can be effectively isolated.

[0083] Furthermore, the sensing assembly 102 includes: a first sensing member 1021 and a second sensing member 1022. A detection area 103 is formed between the first sensing member 1021 and the second sensing member 1022. The cutting wire passes through the detection area 103. When the cutting wire comes into contact with the first sensing member 1021 or the second sensing member 1022, an electrical signal is generated.

[0084] Both the first sensing member 1021 and the second sensing member 1022 are made of conductive materials. In some embodiments, both the first sensing member 1021 and the second sensing member 1022 can be conductive materials such as metals, conductive plastics, and conductive rubbers. Common metals can include gold, silver, copper, iron, tin, aluminum, etc. As an example, the first sensing member 1021 and the second sensing member 1022 in this embodiment can be set as copper rods.

[0085] In this embodiment, the sensing assembly 102 can be set to two and symmetrically disposed on the bracket 101. The driving unit 200 drives the first sensing member 1021 and the second sensing member 1022 to approach or move away from each other to achieve an opening and closing action. The diamond wire passes through the detection area 103 between the first sensing member 1021 and the second sensing member 1022. When the driving unit 200 drives the first sensing member 1021 and the second sensing member 1022 to move towards each other, during the process from the open state to the closed state, according to the electrical signal generated when the diamond wire first comes into contact with one of the sensing members, the inclination direction of the diamond wire on the wire reel can be determined, and the inclination direction is the direction of the sensing member in contact with the diamond wire.

[0086] In some embodiments, when the first sensing member 1021 and the second sensing member 1022 are in a closed state, there is a gap between the first sensing member 1021 and the second sensing member 1022. In this embodiment, after the first sensing member 1021 and the second sensing member 1022 are completely closed, there is a gap between them, which can leave a space for the diamond wire to move between the first sensing member 1021 and the second sensing member 1022, rather than being clamped and contacted by the first sensing member 1021 and the second sensing member 1022 to generate an electrical signal, which affects the detection of the deviation correction device 11 and the accuracy of the deviation correction result. It can be understood that when the first sensing member 1021 and the second sensing member 1022 are completely closed, the diamond wire does not contact any of the sensing members in the gap between them and thus no electrical signal is generated, indicating that the diamond wire is in the gap between them, indicating that the diamond wire is in an approximately vertical state. Therefore, by leaving a gap between the first sensing member 1021 and the second sensing member 1022 after complete closure, the vertical state of the diamond wire can be further judged, and the accuracy of the detection and deviation correction result of the deviation correction device 11 can be further improved. In addition, the gap between the first sensing member 1021 and the second sensing member 1022 allows the cutting wire to continuously pass through the detection area

[0087] In some embodiments, the driving part 200 is one of a parallel opening and closing type air gripper, a cylinder, an oil cylinder, an electric push rod, and a screw motor. In this embodiment, the driving part 200 takes a parallel opening and closing type air gripper as an example. The parallel opening and closing type air gripper can improve the problem that the sensing assembly 102 tilts during the opening and closing operation, and can perform the opening and closing operation at any time according to needs, realizing fast and precise opening and closing actions, and improving work efficiency.

[0088] Taking the deviation correction device 11 as an example and disposed on the circumferential side of the cutting wire between the wire pay-off reel 1211 and the wire arranging wheel 1212, please refer to Figure 3 , the diamond wire passes through the detection area 103 between the first sensing member 1021 and the second sensing member 1022. If the sensing member on the left is the first sensing member 1021, then the sensing member on the right is the second sensing member 1022.

[0089] The electronic control system 13 sends a control instruction to the driving unit 200. The driving unit 200 receives the control instruction and starts to work. When the driving unit 200 drives the first sensing element 1021 and the second sensing element 1022 to move towards each other (as shown in Figure 4(a)), during the process from the open state to the closed state, the conductive first sensing element 1021 first contacts the wire saw to form an energized loop and generates an electrical signal (as shown in Figure 4(b)). At this time, it can be determined that the wire saw is in an inclined state. According to the electrical signal generated when the first sensing element 1021 contacts the wire saw, the direction where the first sensing element 1021 that triggers the electrical signal is located can be determined as the current inclination direction of the wire saw. In Figure 4(a), the wire saw shown is inclined to the left. After the first sensing element 1021 contacts the wire saw and generates an electrical signal, the driving unit 200 continues to drive the first sensing element 1021 and the second sensing element 1022 to continue moving until the first sensing element 1021 and the second sensing element 1022 are completely closed. In the gap between the first sensing element 1021 and the second sensing element 1022, the wire saw still contacts the first sensing element 1021 (as shown in Figure 4(c)).

[0090] Please refer to Figure 5 As shown, the first sensing element 1021 sends the generated electrical signal to the processing component 400. After the processing component 400 receives the electrical signal generated by the first sensing element 1021, it sends a control instruction to the moving component 300. After the moving component 300 receives the instruction, it starts to drive the driving unit 200, the sensing unit 100, and the wire arranging wheel 1212 to move to the left together. The wire saw that was originally inclined to the left is gradually adjusted to a state that tends to be perpendicular to the wire feeding roller 1211. When the wire saw is separated from the first sensing element 1021 and the electrical signal disappears, it can be determined that the wire saw is perpendicular to the main axis of the wire feeding roller 1211 at this time, and the wire deviation correction device 11 completes the wire deviation correction of the wire saw (as shown in Figure 4(d) and Figure 5 as shown).

[0091] After the wire deviation correction is completed, the driving unit 200 is controlled to start working through the electronic control system 13. The driving unit 200 controls the first sensing element 1021 and the second sensing element 1022 to open. Then, the cutting system 12 is controlled to continue to perform cyclic reciprocating wire running from the wire feeding area 121 to the cutting area 122 and then to the wire winding area 123 through the electronic control system 13 to cut the hard material.

[0092] Therefore, in this embodiment, when the diamond wire is payed out from the pay-off reel 1211 and tilted, the deviation rectifying device 11's sensing component 102 detects the diamond wire, and determines the current tilting direction of the diamond wire according to the position of the sensing component 102 that triggers the electric signal. According to the tilting direction of the diamond wire, the processing component 400 of the deviation rectifying device 11 receives the electric signal triggered by the sensing component 102 contacting the diamond wire, issues a control instruction to the moving component 300. After receiving the instruction, the moving component 300 drives the driving part 200, the sensing part 100 and the wire arranging wheel 1212 to move in the tilting direction of the diamond wire, so as to adjust the diamond wire from a tilted state to an approximately vertical state with the pay-off reel 1211, thereby realizing the deviation rectification of the diamond wire, timely correcting the deviation between the wire arranging pitch of the diamond wire on the pay-off reel 1211 and the theoretical wire arranging pitch of the cutting system 12, reducing the probability of the diamond wire being obliquely pulled or tilted during the wire running process, further reducing the probability of the diamond wire breaking, and thus improving the cutting efficiency of the diamond wire and the quality of the cut product.

[0093] In the above embodiment, according to the tilting direction of the diamond wire, the processing component 400 of the deviation rectifying device 11 receives the electric signal triggered by the sensing component 102 contacting the diamond wire, issues a control instruction to the moving component 300. After receiving the instruction, the moving component 300 drives the driving part 200, the sensing part 100 and the wire arranging wheel 1212 to move in the tilting direction of the diamond wire. During the movement, the sensing part 100 gradually disengages from the diamond wire. When the sensing part 100 disengages from the diamond wire and the electric signal disappears, it can be determined therefrom that the diamond wire changes from a tilted state to an approximately vertical state with the pay-off reel 1211, thereby realizing the deviation rectification of the diamond wire.

[0094] In some other embodiments, according to the tilting direction of the diamond wire, the processing component 400 of the deviation rectifying device 11 receives the electric signal triggered by the sensing component 102 contacting the diamond wire, issues a control instruction to the electronic control system 13, and the electronic control system 13 receives the instruction to control the pay-off reel 1211 to move in the direction opposite to the tilting direction of the diamond wire, so as to adjust the diamond wire from a tilted state to an approximately vertical state with the pay-off reel 1211, thereby realizing the deviation rectification of the diamond wire.

[0095] In another embodiment, take the deviation rectifying device 11 being arranged between the first guide wheel 1222 and the main roller 1221 and the cutting wire being able to pass through the sensing part 100 of the deviation rectifying device 11 as an example. Please refer to Figure 6 As shown, the diamond wire passes through the detection area 103 between the first sensing element 1021 and the second sensing element 1022. Similarly, if the sensing element on the left is the first sensing element 1021, then the sensing element on the right is the second sensing element 1022.

[0096] The diamond wire is introduced into the main roller 1221 through the first guide pulley 1222 and wound around the groove 12210 of the main roller 1221 to form a multi-loop cutting wire mesh 1223. As shown in Fig. 7(a), when the diamond wire enters the groove 12210 of the main roller 1221, it is not perpendicular to the main roller 1221, so that the diamond wire is not at the bottom of the groove 12210, resulting in a tendency to move towards the bottom of the groove 12210. At this time, the force exerted by the diamond wire on the groove 12210 of the main roller 1221 can be decomposed into a component force F' perpendicular to the bottom of the groove 12210 and a component force F" along the inclined direction of the groove 12210. These two component forces cause the diamond wire to twist in the groove 12210, thereby increasing the probability of diamond wire breakage and affecting the cutting efficiency.

[0097] To solve this problem, in this embodiment, the deviation rectifying device 11 is arranged on the circumferential side of the cutting wire between the first guide pulley 1222 and the main roller 1221 to improve the problem that the diamond wire is inclined due to non-perpendicularity in the groove 12210 of the main roller 1221, so as to reduce the probability of diamond wire breakage and improve the cutting efficiency.

[0098] The principle of the deviation rectifying device 11 in this embodiment for rectifying the diamond wire is similar to that of the deviation rectifying device 11 shown in Figures 3 - 5 The specific deviation rectifying process is as follows: The electric control system 13 sends a control instruction to the driving part 200, and the driving part 200 receives the control instruction and starts to work. When the driving part 200 drives the first sensing part 1021 and the second sensing part 1022 to move towards each other, during the process from the open state to the closed state, the conductive second sensing part 1022 contacts the diamond wire first to form an energized loop and generate an electrical signal. At this time, it can be judged that the diamond wire is in an inclined state, that is, the diamond wire is not perpendicular to the main roller 1221. Figure 6 In

[0099] In some embodiments, warning parts can also be arranged on the deviation rectifying device 11. The warning parts can be set to two, which are electrically connected to the first sensing part 1021 and the second sensing part 1022 respectively. The warning parts can be warning lights or buzzers and other structures with a prompting function. Through the warning parts, the state of the electrical signal generated after the first sensing part 1021 or the second sensing part 1022 contacts the diamond wire can be quickly and intuitively feedback. For example, when one of the sensing parts contacts the diamond wire to generate an electrical signal, the warning light corresponding to the sensing part can light up or the buzzer can give an alarm. The processing part 400 can quickly judge the inclination direction of the diamond wire according to the electrical signal and the prompting signal, so as to control the deviation rectifying device 11 and the first guide pulley 1222 to move towards the direction of the second sensing part 1022 where the warning prompt is issued (i.e., the inclination direction of the diamond wire) (as shown in Fig. 7(a)).

[0100] In some embodiments, the warning component can be electrically connected to the processing component 400. When the driving unit 200 drives the first sensing component 1021 and the second sensing component 1022 to move towards each other from the open state to the closed state, the conductive second sensing component 1022 first contacts the wire saw to form a closed circuit, generating an electrical signal. At the same time, the warning component electrically connected to the second sensing component 1022 lights up or the buzzer gives an alarm. The processing component 400 quickly determines the inclination direction of the wire saw based on the received electrical signal and the current signal generated when the warning component works, and thus controls the deviation rectifying device 11 and the first guide pulley 1222 to move in the direction of the second sensing component 1022 that gives the warning hint (i.e., the inclination direction of the wire saw) (as shown in FIG. 7(b)).

[0101] In some other embodiments, an image acquisition module can also be provided on the deviation rectifying device 11. The image acquisition module can be structures such as a camera or a video camera capable of acquiring images. When the driving unit 200 drives the first sensing component 1021 and the second sensing component 1022 to move towards each other from the open state to the closed state, the conductive second sensing component 1022 first contacts the wire saw to form a closed circuit, generating an electrical signal. At the same time, the warning component electrically connected to the second sensing component 1022 lights up. The image acquisition module acquires the image information of the lit warning component and sends the image information to the processing component 400. The processing component 400 quickly determines that the inclination direction of the wire saw is the direction of the second sensing component 1022 based on the received electrical signal and the image information, and thus controls the deviation rectifying device 11 and the first guide pulley 1222 to move in the direction of the second sensing component 1022 that gives the warning hint (i.e., the inclination direction of the wire saw) (as shown in FIG. 7(b)).

[0102] In some other embodiments, a light sensor can also be provided on the deviation rectifying device 11. When the driving unit 200 drives the first sensing component 1021 and the second sensing component 1022 to move towards each other from the open state to the closed state, the conductive second sensing component 1022 first contacts the wire saw to form a closed circuit, generating an electrical signal. At the same time, the warning component electrically connected to the second sensing component 1022 lights up. The light sensor detects the lighting signal of the warning component and sends the lighting signal to the processing component 400. The processing component 400 quickly determines that the inclination direction of the wire saw is the direction of the second sensing component 1022 based on the received electrical signal and the lighting signal, and thus controls the deviation rectifying device 11 and the first guide pulley 1222 to move in the direction of the second sensing component 1022 that gives the warning hint (i.e., the inclination direction of the wire saw) (as shown in FIG. 7(b)).

[0103] In the above several embodiments, as shown in FIG. 7(b), as the deviation rectifying device 11 and the first guide pulley 1222 continuously move to the right, the wire saw that was originally not perpendicular to the groove 12210 of the main roller 1221 gradually moves to the bottom of the groove 12210. When the wire saw is separated from the second sensing member 1022 and the electrical signal disappears, the warning member electrically connected to the second sensing member 1022 no longer lights up or emits a beeping alarm. At this time, it can be judged that the wire saw is perpendicular to the main roller 1221, and the deviation rectifying device 11 completes the deviation rectification of the wire saw.

[0104] After the deviation rectification is completed, the electric control system 13 controls the cutting system 12 to continue running the wire in a cyclic reciprocating manner from the wire feeding area 121 to the cutting area 122 and then to the wire collecting area 123 to cut the hard material.

[0105] In some other embodiments, the electric control system 13 sends a control instruction to the driving part 200. The driving part 200 receives the control instruction and starts to work. When the driving part 200 drives the first sensing member 1021 and the second sensing member 1022 to move towards each other and changes from the open state to the closed state, the conductive second sensing member 1022 first contacts the wire saw to form a closed circuit, generating an electrical signal. At the same time, the corresponding warning member lights up or the buzzer emits an alarm. The operator can quickly determine the tilting direction of the wire saw according to the lit warning member or the buzzer that emits an alarm. By manually moving the first guide pulley 1222 in the direction indicated by the warning member (or the second sensing member 1022), during the movement, when the wire saw is separated from the second sensing member 1022 and the electrical signal disappears, the warning member electrically connected to the second sensing member 1022 no longer lights up or emits a beeping alarm. At this time, it can be judged that the wire saw is perpendicular to the main roller 1221, and the deviation rectifying device 11 completes the deviation rectification of the wire saw. The wire saw is now at the bottom of the groove 12210 of the main roller 1221 and is perpendicular to the main roller 1221.

[0106] After the wire saw is introduced from the first guide pulley 1222 to the main roller 1221, the deviation rectifying device 11 detects the wire saw through the sensing assembly 102. According to the position of the sensing assembly 102 that triggers the electrical signal, as well as the position of the lit warning member or the alarm signal of the buzzer, quickly judge whether the current tilting direction of the wire saw is perpendicular to the main roller 1221. The processing component 400 of the deviation rectifying device 11 receives the electrical signal triggered by the sensing assembly 102 contacting the wire saw, as well as the lit signal of the warning member or the alarm signal of the buzzer, and controls the deviation rectifying device 11 and the first guide pulley 1222 to move together in the direction of the sensing member that issues the warning prompt, so as to adjust the wire saw to be perpendicular to the main roller 1221, thereby realizing the deviation rectification of the wire saw, improving the torsional problem of the wire saw in the groove 12210 of the main roller 1221, reducing the wire breakage probability of the wire saw, and improving the cutting efficiency and the cutting quality of the product.

[0107] In the above embodiments, according to the inclination direction of the diamond wire, the processing component 400 of the deviation rectifying device 11 receives the electrical signal triggered by the contact between the induction component 102 and the diamond wire, sends a control instruction to the moving component 300, and after receiving the instruction, the moving component 300 drives the driving part 200 and the induction part 100 to move in the direction of the induction piece that issues a warning prompt together with the first guide wheel 1222, so as to adjust the diamond wire to be perpendicular to the main roller 1221, thereby realizing the deviation rectification of the diamond wire.

[0108] In some other embodiments, according to the inclination direction of the diamond wire, the processing component 400 of the deviation rectifying device 11 receives the electrical signal triggered by the contact between the induction component 102 and the diamond wire, sends a control instruction to the electronic control system 13, and the electronic control system 13 receives the instruction and controls the main roller 1221 to move in the direction opposite to the inclination direction of the diamond wire, so as to adjust the diamond wire to be perpendicular to the main roller 1221, thereby realizing the deviation rectification of the diamond wire.
