Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cutting, and particularly relates to a cutting liquid spraying device, a cutting liquid supply system and a wire cutting equipment. BACKGROUND

[0002] Wire cutting is a processing method for cutting a workpiece to be cut by high-speed movement of a cutting wire. For example, the wire cutting can be used to cut a silicon rod, a semiconductor, silicon carbide, sapphire, magnetic material and the like. During the cutting process, the cutting liquid is usually sprayed to the cutting position of the workpiece to be cut, so as to take away the heat generated during the cutting process, play a lubricating role, and take away the powder and other impurities generated during the cutting process.

[0003] In the related art, a spraying pipe is arranged in the cutting equipment, a liquid pump is used to pump the cutting liquid into the spraying pipe, and then the liquid outlet of the spraying pipe is used to spray the cutting liquid to the intersection of the cutting wire and the workpiece to be cut. However, the spraying pipe in the cutting equipment in the related art usually sprays liquid through a single liquid outlet, which is prone to problems such as uneven liquid flow and even liquid flow interruption, resulting in poor cutting effect. CONTENT OF THE INVENTION

[0004] The application aims to provide a cutting liquid spraying device, a cutting liquid supply system and a wire cutting equipment, which can solve the problem that the spraying pipe in the cutting equipment in the related art is prone to problems such as uneven liquid flow and even liquid flow interruption, resulting in poor cutting effect.

[0005] In order to solve the above technical problems, the application is implemented as follows:

[0006] In a first aspect, the application embodiment provides a cutting liquid spraying device, comprising:

[0007] A liquid guide pipe, wherein a liquid inlet cavity is arranged in the liquid guide pipe;

[0008] A spray head assembly, wherein the spray head assembly is connected with the liquid guide pipe, the spray head assembly is provided with a first liquid outlet and a second liquid outlet, the first liquid outlet and the second liquid outlet are respectively communicated with the liquid inlet cavity, the liquid spraying direction of the first liquid outlet intersects with the liquid spraying direction of the second liquid outlet, the first liquid outlet is used to spray the cutting liquid to the intersection of the cutting wire and the workpiece to be cut, and the second liquid outlet is used to spray the cutting liquid to the part of the cutting wire except the intersection with the workpiece to be cut.

[0009] In the present application, two liquid spraying openings are arranged on the nozzle assembly, and the two liquid spraying openings are communicated with the liquid inlet cavities in the liquid guide pipes, so as to spray liquid near the cutting position by the two liquid spraying openings respectively. Through the synergistic effect of the two liquid spraying openings, the cooling and wetting effects on the cutting line can be effectively improved, and the powder and other sundries generated in the cutting process can be timely removed, so that the influence of the abnormal spraying of a single liquid spraying opening on the cutting performance can be avoided. In addition, through the simultaneous spraying of the two liquid spraying openings, the spraying amount of the cutting liquid can be increased, and thus the resistance of the cutting line caused by the adhesion of the cut part of the to-be-cut part can be reduced.

[0010] Further, the liquid spraying directions of the two liquid spraying openings are intersected, so that the cutting liquid can be sprayed to different positions by the two liquid spraying openings. Specifically, the cutting liquid can be sprayed to the intersection of the cutting line and the to-be-cut part by the first liquid spraying opening, and the cutting liquid can be sprayed to the part of the cutting line except the intersection with the to-be-cut part by the second liquid spraying opening. In this way, when the first liquid spraying opening is abnormal, the second liquid spraying opening can still spray the cutting liquid to the cutting line, so that the cutting line can be cooled and wetted in time, and thus the stable cutting force and lubricity of the cutting line can be ensured, and the probability of abnormality of the cutting line can be reduced, so that the stable cutting force of the cutting line can be improved, and the cutting yield can be improved.

[0011] In a second aspect, an embodiment of the present application provides a cutting liquid supply system, which comprises the cutting liquid spraying device in the first aspect.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] The cutting fluid spraying device, the cutting fluid supply system and the wire cutting equipment provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0027] As shown in Figure 1 and Figure 2 , the cutting fluid spraying device 1 according to some embodiments of the present application comprises a liquid guide pipe 10 and a spray head assembly 20, the liquid guide pipe 10 is provided with a liquid inlet cavity 11, the spray head assembly 20 is connected with the liquid guide pipe 10, the spray head assembly 20 is provided with a first liquid spraying port 201 and a second liquid spraying port 202, the first liquid spraying port 201 and the second liquid spraying port 202 are respectively communicated with the liquid inlet cavity 11, the liquid spraying direction of the first liquid spraying port 201 (as shown by the dotted arrow F1 in Figure 2 ) intersects with the liquid spraying direction of the second liquid spraying port 202 (as shown by the dotted arrow F2 in Figure 2 ), the first liquid spraying port 201 is used for spraying cutting fluid to the intersection of the cutting wire and the to-be-cut part, and the second liquid spraying port 202 is used for spraying cutting fluid to the part of the cutting wire except the intersection with the to-be-cut part.

[0028] In the embodiments of the present application, two liquid spraying ports are arranged on the spray head assembly 20, the two liquid spraying ports are respectively communicated with the liquid inlet cavity 11 in the liquid guide pipe 10, so as to spray liquid near the cutting position by using the two liquid spraying ports respectively, through the synergistic effect of the two liquid spraying ports, the cooling and wetting effect on the cutting wire can be effectively improved, and the powder and other sundries generated in the cutting process can be timely taken away, so as to avoid the influence on the cutting performance due to the abnormal spraying of a single liquid spraying port. In addition, through the simultaneous spraying of the two liquid spraying ports, the spraying amount of the cutting fluid can be increased, thereby helping to reduce the resistance of the cutting wire due to the adhesion of the to-be-cut part.

[0029] Furthermore, by making the spraying directions of the two spray nozzles intersect, the two spray nozzles can spray cutting fluid in different directions. Specifically, the first spray nozzle 201 can spray cutting fluid at the junction of the cutting line and the workpiece to be cut, and the second spray nozzle 202 can spray cutting fluid on the portion of the cutting line other than the junction with the workpiece to be cut. This ensures that even if the first spray nozzle 201 malfunctions, the second spray nozzle 202 can still continue to spray cutting fluid onto the cutting line, achieving timely cooling and wetting of the cutting line. This ensures stable cutting force and lubrication of the cutting line, reduces the probability of abnormalities in the cutting line, and thus improves the stable cutting force and the yield of cut products.

[0030] It is understood that the cutting fluid spraying device 1 in this application can be applied to wire cutting equipment. When cutting with wire cutting equipment, the cutting wire set in the equipment moves at high speed under the drive of the roller, thereby realizing the cutting effect on the workpiece to be cut. For example, it can be applied to silicon rod slicing process.

[0031] Furthermore, by installing a spray device in the online cutting equipment, the spray device is connected to the cutting fluid storage device. The cutting fluid in the cutting fluid storage device is sent into the spray device by a power mechanism such as a delivery pump. The spray device sprays the cutting fluid onto the junction of the cutting line and the workpiece to be cut (such as a silicon rod). The cutting fluid carries away the heat generated during the cutting process. The cutting fluid also acts as a lubricant between the cutting line and the workpiece to be cut. At the same time, the cutting fluid can also carry away the powder and other impurities generated during the cutting process, which helps to improve the cutting effect.

[0032] However, in traditional wire EDM equipment, the spraying device typically has only a single nozzle. After the cutting fluid is fed into the spraying device, it is sprayed through the nozzle to the cutting position between the cutting wire and the workpiece. If the nozzle becomes blocked or other abnormalities occur, it can lead to uneven or even interrupted flow of the cutting fluid. This can cause the high-speed cutting wire to heat up rapidly, resulting in a sharp drop in the cutting force and abrupt changes in the cutting trajectory, severely affecting the cutting effect.

[0033] To this end, two liquid outlets are provided in the spraying device in the present application, and the two liquid outlets spray cutting liquid to the vicinity of the cutting position together, which can significantly improve the cooling and lubricating effect on the cutting wire compared with a single liquid outlet, and improve the cutting ability of the cutting wire. Further, the first liquid outlet 201 can be used to spray cutting liquid to the intersection between the cutting wire and the to-be-cut piece to assist the cutting action of the cutting wire, and the second liquid outlet 202 can be used to spray cutting liquid to the part of the cutting wire other than the intersection with the to-be-cut piece. In this way, even if the first liquid outlet 201 is blocked or the like, the second liquid outlet 202 can still spray cutting liquid to cool the cutting wire in time, thereby ensuring the cutting performance and lubricity of the cutting wire and reducing the probability of cutting abnormality.

[0034] In addition, after the cutting is completed, the to-be-cut piece needs to be separated from the cutting wire to realize the lifting operation. In this process, the cutting wire is clamped in the to-be-cut piece after cutting, and the two liquid outlets spray cutting liquid to different positions between the to-be-cut piece and the cutting wire at the same time, which can reduce the resistance of the to-be-cut piece to the cutting wire, thereby facilitating the withdrawal of the cutting wire from the to-be-cut piece.

[0035] Specifically, the cutting liquid spraying device 1 comprises a liquid guide pipe 10 and a spray head assembly 20. The liquid guide pipe 10 is provided with a liquid inlet cavity 11. The liquid inlet cavity 11 of the liquid guide pipe 10 can be communicated with a cutting liquid storage device to introduce cutting liquid into the liquid inlet cavity 11 of the liquid guide pipe 10 from the cutting liquid storage device. Meanwhile, the first liquid outlet 201 and the second liquid outlet 202 are arranged in the spray head assembly 20, and the liquid spraying direction of the first liquid outlet 201 intersects with the liquid spraying direction of the second liquid outlet 202, that is, the orientation of the first liquid outlet 201 is different from the orientation of the second liquid outlet 202 in the spray head assembly 20, as shown in the figure. The first liquid outlet 201 is directed to the direction of the dotted arrow F1, and the second liquid outlet 202 is directed to the direction of the dotted arrow F2, so as to spray cutting liquid to different positions in the wire cutting equipment by the first liquid outlet 201 and the second liquid outlet 202, thereby better assisting the cutting operation. Figure 2

[0036] In some embodiments, the first liquid outlet 201 and / or the second liquid outlet 202 can be two long strip-shaped slit holes opened in the spray head assembly 20. The long strip-shaped slit holes can extend along the axis direction of the liquid guide pipe 10 to ensure that the cutting liquid sprayed by the liquid outlet can cover a larger area, thereby meeting the cutting process requirements.

[0037] It should be noted that the specific structure and position of the first liquid outlet 201 and the second liquid outlet 202 in the spray head assembly 20 can be flexibly set according to actual conditions, which is not limited herein.

[0038] ​In addition, the cutting liquid spraying device 1 of the present application can work simultaneously or only by one of the first liquid spraying port 201 and the second liquid spraying port 202 when used for assisting cutting. The specific use of the first liquid spraying port 201 and the second liquid spraying port 202 can be flexibly set according to process needs, which is not limited herein.

[0039] Optionally, as shown in Figure 2 , the angle between the spraying direction of the first liquid spraying port 201 and the spraying direction of the second liquid spraying port 202 is an included angle a, which satisfies: 15°≤a≤75°. For example, the included angle a can be set as: 15°, 20°, 30°, 40°, 50°, 60°, 70°, 75°, or any angle or a range between any two angles.

[0040] In the embodiments of the present application, by setting the angle range of the included angle a between the spraying direction of the first liquid spraying port 201 and the spraying direction of the second liquid spraying port 202, the cutting liquid can be sprayed to the intersection between the cutting line and the to-be-cut part by the first liquid spraying port 201 to assist the cutting effect of the cutting line, and at the same time, the cutting liquid can be sprayed to the part of the cutting line except the intersection with the to-be-cut part by the second liquid spraying port 202 to cool the cutting line and simultaneously play a supplementary assisting role to the first liquid spraying port 201.

[0041] It can be understood that if the included angle a is too small, the first liquid spraying port 201 and the second liquid spraying port 202 are parallel or approximately parallel, and the cutting liquid sprayed by the two liquid spraying ports all falls near the intersection between the cutting line and the to-be-cut part, which not only causes the second liquid spraying port 202 to lose the effective supplement and assistance to the first liquid spraying port 201, but also causes too much cutting liquid at the cutting position to affect the cutting effect.

[0042] If the included angle a is too large, the positions where the cutting liquid sprayed by the first liquid spraying port 201 and the second liquid spraying port 202 falls on the cutting line are too far apart, so that the cutting liquid sprayed by the second liquid spraying port 202 cannot play a timely cooling role on the cutting line, and the second liquid spraying port 202 also loses the effective supplement and assistance to the first liquid spraying port 201.

[0043] Optionally, as shown in Figure 1 and Figure 2 , the spray head assembly 20 includes a spray head 21, the first liquid spraying port 201 and the second liquid spraying port 202 are arranged on the spray head 21, the spray head 21 is provided with a first cavity 211 and a second cavity 212 which are isolated from each other, the first liquid spraying port 201 communicates with the first cavity 211, the second liquid spraying port 202 communicates with the second cavity 212, and the first liquid spraying port 201 and the second liquid spraying port 202 respectively communicate with the liquid inlet cavity 11.

[0044] In the embodiment of the present application, the first cavity 211 and the second cavity 212 are arranged in the nozzle 21 respectively, the first cavity 211 guides part of the cutting liquid in the liquid inlet cavity 11 to the first liquid spraying port 201, and the second cavity 212 guides part of the cutting liquid in the liquid inlet cavity 11 to the second liquid spraying port 202, so that the cutting liquid is precisely guided, and the continuity and uniformity of the cutting liquid supplied to the first liquid spraying port 201 and the second liquid spraying port 202 are ensured.

[0045] In some embodiments, the volume of the first cavity 211 is greater than or equal to the volume of the second cavity 212. It can be understood that the first liquid spraying port 201 is used to spray the cutting liquid to the intersection of the cutting line and the to-be-cut part, and plays a main auxiliary cutting role, and therefore, by setting the volume of the first cavity 211 to be greater than or equal to the volume of the second cavity 212, it is ensured that the cutting liquid in the first cavity 211 is sufficient to meet the liquid spraying demand of the first liquid spraying port 201.

[0046] Optionally, as shown in Figure 2 and Figure 3 , the liquid guide pipe 10 is provided with two through hole rows 12, each through hole row 12 includes a plurality of through holes 121 arranged along the axial direction of the liquid guide pipe 10, one of the through hole rows 12 communicates the liquid inlet cavity 11 and the first cavity 211, and the other through hole row 12 communicates the liquid inlet cavity 11 and the second cavity 212.

[0047] In the embodiment of the present application, two through hole rows 12 are arranged in the liquid guide pipe 10, one of the through hole rows 12 communicates the first cavity 211, and the other through hole row 12 communicates the second cavity 212, and each through hole row 12 includes a plurality of through holes 121, so that the cutting liquid in the liquid inlet cavity 11 is guided into the first cavity 211 and the second cavity 212 through the through hole row 12, and the position and structure of the plurality of through holes 121 in the through hole row 12 are set to ensure the smoothness and uniformity of the flow of the cutting liquid between the liquid inlet cavity 11 and the first cavity 211 and the second cavity 212.

[0048] It should be noted that the through hole row 12 communicating with the first cavity 211 and the through hole row 12 communicating with the second cavity 212 can have the same structure or different structures. The through holes 121 constituting the through hole row 12 can be circular holes, elliptical holes, waist holes, polygonal holes, etc., and the shape and position of the through holes 121 in each through hole row 12 can be flexibly set according to actual needs, which is not limited herein.

[0049] Optionally, as shown in Figure 1 and Figure 3As shown, the liquid guide pipe 10 is also provided with a liquid inlet 13 communicating with the liquid inlet cavity 11, for introducing cutting liquid into the liquid inlet cavity 11; and the through hole row 12 communicating with the first cavity 211, the hole diameter of the through hole 121 far from the liquid inlet 13 is greater than the hole diameter of the through hole 121 close to the liquid inlet 13.

[0050] It can be understood that when the cutting liquid flows into the liquid inlet cavity 11 from the liquid inlet 13, the flow rate will decrease with the increase of the flow distance, therefore, by setting the through hole row 12 communicating with the first cavity 211, the hole diameter of the through hole 121 far from the liquid inlet 13 is greater than the hole diameter of the through hole 121 close to the liquid inlet 13, to ensure that the flow of the cutting liquid introduced by the through hole 121 far from the liquid inlet 13 is the same or similar to the flow of the cutting liquid introduced by the through hole 121 close to the liquid inlet 13, so that the uniformity of the cutting liquid introduced into the first cavity 211 by the entire through hole row 12 can be improved, and the uniformity of the cutting liquid sprayed by the first liquid outlet 201 can be further improved.

[0051] Similarly, the through hole row 12 communicating with the second cavity 212 can be set, the hole diameter of the through hole 121 far from the liquid inlet 13 is greater than the hole diameter of the through hole 121 close to the liquid inlet 13. In this way, the uniformity of the cutting liquid introduced into the second cavity 212 by the entire through hole row 12 can be ensured, and the uniformity of the cutting liquid sprayed by the second liquid outlet 202 can be further improved.

[0052] Optionally, as shown, Figure 2 The first cavity 211 includes a first end 211a close to the through hole row 12 and a second end 211b close to the first liquid outlet 201, and the flow cross-sectional area of the first cavity 211 presents a decreasing trend from the first end 211a to the second end 211b.

[0053] In the embodiments of the present application, by setting the flow cross-sectional area of the first cavity 211 from the first end 211a to the second end 211b presents a decreasing trend, that is, the first cavity 211 presents a shrinking trend from the first end 211a to the second end 211b, so that when the cutting liquid flows from the first end 211a to the second end 211b, the cutting liquid can be pressurized, thereby ensuring that the cutting liquid sprayed from the first liquid outlet 201 can be dispersed to form a liquid film with uniform thickness, and then uniformly fall to the intersection of the cutting line and the to-be-cut part, so that the cutting liquid can better lubricate and cool the cutting line.

[0054] It can be understood that the flow cross-sectional area of the first cavity 211 is the cross-sectional area of the first cavity 211 along the direction perpendicular to the axis of the liquid guide pipe.

[0055] Optionally, as shown, Figure 2As shown, the second cavity 212 includes a third end 212a close to the row of through holes 12 and a fourth end 212b close to the second liquid ejection port 202, and the flow area of the second cavity 212 decreases from the third end 212a to the fourth end 212b.

[0056] In the embodiment of the present application, the flow area of the second cavity 212 decreases from the third end 212a to the fourth end 212b, that is, the second cavity 212 is tapered from the third end 212a to the fourth end 212b. Thus, when the cutting liquid in the second cavity 212 flows from the third end 212a to the fourth end 212b, the cutting liquid can be pressurized, thereby ensuring that the cutting liquid ejected from the second liquid ejection port 202 forms a liquid film with uniform thickness, which is then uniformly scattered on the cutting line to achieve the cooling and wetting effects of the cutting liquid.

[0057] It can be understood that the flow area of the second cavity 212 is the cross-sectional area of the second cavity 212 along the direction perpendicular to the axis of the liquid guide tube.

[0058] Optionally, as shown in Figure 1 and Figure 2 The spray head assembly 20 further includes a first adjusting plate 22, which is arranged at the first liquid ejection port 201 and movably connected to the spray head 21. The first adjusting plate 22 can be moved relative to the spray head 21 to adjust the size of the first liquid ejection port 201.

[0059] In the embodiment of the present application, the first adjusting plate 22 is movably connected to the spray head 21 at the first liquid ejection port 201. By moving the first adjusting plate 22, the shielding area of the first adjusting plate 22 on the first liquid ejection port 201 can be changed, thereby adjusting the size of the first liquid ejection port 201 to precisely control the flow of the cutting liquid ejected from the first liquid ejection port 201.

[0060] In some embodiments, the spray head assembly 20 further includes a bolt, the spray head 21 is provided with a mounting portion at the first liquid ejection port 201, and the first adjusting plate 22 is provided with a strip-shaped hole. The bolt is screwed through the strip-shaped hole in the first adjusting plate 22 and connected with the mounting portion, and the first adjusting plate 22 at least partially extends to shield the first liquid ejection port 201. In use, the thickness of the liquid film of the cutting liquid ejected from the first liquid ejection port 201 can be adjusted by loosening the bolt and adjusting the position of the first adjusting plate 22, and the position of the first adjusting plate 22 can be fixed by tightening the bolt after adjustment.

[0061] Of course, the first adjusting plate 22 and the spray head 21 can also adopt other adjustable connection structures, which can be flexibly arranged according to actual needs, and are not limited herein.

[0062] Optionally, as shown in Figure 2 The spray head assembly 20 further comprises a second adjusting plate 23, which is arranged at the second liquid outlet 202 and movably connected to the spray head 21. The second adjusting plate 23 is movable relative to the spray head 21 to adjust the size of the second liquid outlet 202.

[0063] In the embodiment, the second adjusting plate 23 is movably connected to the spray head 21 at the second liquid outlet 202. The size of the second liquid outlet 202 can be adjusted by moving the second adjusting plate 23 to precisely control the cutting liquid sprayed from the second liquid outlet 202.

[0064] In some embodiments, the second liquid outlet 202 is arranged at the bottom of the spray head 21, and the spray head 21 is provided with mounting plates on the opposite sides of the second liquid outlet 202. The mounting plates are provided with sliding grooves, and the end of the second adjusting plate 23 is slidably connected to the sliding grooves. The second adjusting plate 23 at least partially extends to shield the second liquid outlet 202. The second adjusting plate 23 can be pushed and pulled to adjust the shielding area of the second adjusting plate 23 on the second liquid outlet 202, so as to adjust the flow of the cutting liquid sprayed from the second liquid outlet 202.

[0065] Of course, other adjustable connection structures can be used between the second adjusting plate 23 and the spray head 21. The skilled in the art can make flexible settings according to actual needs, which are not limited herein.

[0066] Optionally, as shown in Figure 1 The cutting liquid spraying device 1 further comprises a cleaning pipe 30 connected to the spray head assembly 20. The cleaning pipe 30 is provided with a plurality of spraying holes 31. Cleaning liquid, such as water, can be introduced into the cleaning pipe 30. After cutting, the spraying holes 31 of the cleaning pipe 30 can spray cleaning liquid to the cut workpiece to realize the flushing effect of the workpiece.

[0067] Optionally, the embodiment further provides a cutting liquid supply system, which comprises a cutting liquid storage device and the cutting liquid spraying device in the above embodiment. The cutting liquid storage device is used to store cutting liquid, and is in communication with the liquid inlet cavity of the liquid guide pipe.

[0068] In the embodiment of the present application, the spray head assembly 20 is provided with two liquid spray openings, which are respectively communicated with the liquid inlet cavity 11 in the liquid guide pipe 10, and the liquid spray directions of the two liquid spray openings intersect, so that the two liquid spray openings can spray cutting liquid in different directions. The first liquid spray opening 201 can spray cutting liquid to the intersection of the cutting line and the to-be-cut part to assist the cutting line in cutting. Meanwhile, the second liquid spray opening 202 can spray cutting liquid to the part of the cutting line other than the intersection with the to-be-cut part, so that when the first liquid spray opening 201 is abnormal, the second liquid spray opening 202 can spray cutting liquid to realize timely cooling and wetting of the cutting line, thereby ensuring the stable cutting force and lubricity of the cutting line and reducing the probability of abnormality of the cutting line. Specifically, the cutting liquid supply system can include a cutting liquid storage device, a delivery pump and the cutting liquid spraying device 1. The cutting liquid storage device is used to store cutting liquid. The input end of the delivery pump is communicated with the cutting liquid storage device, and the output end of the delivery pump is communicated with the liquid inlet cavity 11 of the liquid guide pipe 10.

[0070] In the embodiment of the present application, by providing two liquid spray openings on the spray head assembly 20, the two liquid spray openings are respectively communicated with the liquid inlet cavity 11 in the liquid guide pipe 10, so that the two liquid spray openings can respectively spray liquid near the cutting position. Through the synergistic effect of the two liquid spray openings, the cooling and wetting effect of the cutting line can be effectively improved, and the powder and other sundries generated in the cutting process can be timely removed, thereby avoiding the influence of abnormality of a single liquid spray opening on the cutting performance. In addition, by spraying liquid through the two liquid spray openings at the same time, the spraying amount of the cutting liquid can be increased, thereby helping to reduce the resistance of the cutting line caused by the adhesion of the to-be-cut part.

[0071] Further, the liquid spray directions of the two liquid spray openings intersect, so that the two liquid spray openings can spray cutting liquid in different directions. The first liquid spray opening 201 can spray cutting liquid to the intersection of the cutting line and the to-be-cut part, and the second liquid spray opening 202 can spray cutting liquid to the part of the cutting line other than the intersection with the to-be-cut part. When the first liquid spray opening 201 is abnormal, the second liquid spray opening 202 can also spray cutting liquid to the cutting line to realize timely cooling and wetting of the cutting line, thereby ensuring the stable cutting force and lubricity of the cutting line and reducing the probability of abnormality of the cutting line, thereby improving the stable cutting force of the cutting line and improving the cutting yield.

[0072] Optionally, the wire cutting device further comprises a driving mechanism and a cutting wire; the cutting wire is movably connected to the driving mechanism, and the driving mechanism is configured to drive the cutting wire to move to cut the to-be-cut member; the first liquid spraying port 201 is directed towards the intersection between the cutting wire and the to-be-cut member, and the second liquid spraying port 202 is directed towards the cutting wire.

[0073] In the embodiments of the present application, the driving mechanism is configured to drive the cutting wire to move to perform the cutting operation by using the cutting wire, and the first liquid spraying port 201 is configured to spray the cutting liquid towards the intersection between the cutting wire and the to-be-cut member, and the second liquid spraying port 202 is configured to spray the cutting liquid towards the cutting wire except the intersection between the cutting wire and the to-be-cut member, so as to ensure the cutting quality of the cutting wire.

[0074] In some embodiments, the driving mechanism can comprise a driving member, a driving roller and a driven roller; the driving roller and the driven roller are arranged in a spaced manner, and the cutting wire is arranged around the driving roller and the driven roller; the driving member is in transmission connection with the driving roller, and the driving member is configured to drive the driving roller to rotate, so as to drive the cutting wire to move at a high speed to cut the to-be-cut member, so as to perform the cutting operation by using the cutting wire.

[0075] Further, the cutting liquid spraying device 1 can be arranged above the cutting wire, and the spray head 21 is located between the to-be-cut member and the driving roller; the first liquid spraying port 201 of the spray head 21 is directed towards the intersection between the cutting wire and the to-be-cut member, and the second liquid spraying port 202 is directed towards the cutting wire between the to-be-cut member and the driving roller, so as to spray the cutting liquid from the first liquid spraying port 201 towards the intersection between the cutting wire and the to-be-cut member, and spray the cutting liquid from the second liquid spraying port 202 directly towards the cutting wire. It can be understood that, during the cutting operation by using the cutting wire, the airflow is generated when the driving roller rotates to drive the cutting wire to move at a high speed, and the airflow acts on the liquid film sprayed from the first liquid spraying port 201, which is easy to cause the cutting liquid to deviate from the cutting position of the cutting wire. Therefore, in the present application, the second liquid spraying port 202 is directed towards the cutting wire between the to-be-cut member and the driving roller, i.e., the second liquid spraying port 202 is located between the first liquid spraying port 201 and the driving roller. In this way, the liquid film sprayed from the second liquid spraying port 202 can not only play a role in cooling and wetting the cutting wire, but also play a role in blocking the airflow, so as to avoid the influence of the airflow generated by the rotation of the driving roller on the liquid spraying of the first liquid spraying port 201, thereby facilitating the uniformity and stability of the liquid flow sprayed from the first liquid spraying port 201.

[0076] It should be noted that, during the cutting process, the cutting liquid spraying device 1 can be provided as one or more than two. For example, the cutting liquid spraying device 1 can be provided as two, and the two cutting liquid spraying devices 1 are arranged on the two sides of the to-be-cut member, so as to spray the cutting liquid by using the two cutting liquid spraying devices 1 at the same time, thereby improving the cutting effect. The specific arrangement structure of each cutting liquid spraying device 1 can be implemented by referring to the above embodiments, which will not be described herein.

[0077] In addition, other structures of the wire cutting device can be set according to the related art, which are not limited herein.
