Description

Technical Field

[0001] The present application relates to the technical field of wire cutting, and more specifically, to a spraying device and a wire cutting machine. Background Art

[0002] Wire cutting is a processing method in which a cutting wire reciprocates at a high speed and moves relative to a workpiece to be cut (such as materials like photovoltaic silicon rods, semiconductors, silicon carbide, sapphire, magnetic materials, etc.), so that the cutting wire cuts the workpiece to be cut.

[0003] During the process of cutting the workpiece to be cut, it is necessary to spray a liquid at the cutting part of the workpiece to be cut to reduce the temperature of the cutting part and avoid the influence of excessive temperature of the cutting part on the performance and quality of the workpiece to be cut. At the same time, the sprayed liquid can also play a role in lubricating the cutting wire and the workpiece to be cut, reducing friction, and taking away debris such as powders generated by cutting.

[0004] The sprayed liquid is generally led to a suitable position in the cutting area through a spraying unit to spray the cutting part. Due to the size difference of the workpiece to be cut, for workpieces of different sizes, the positions where they contact the cutting wire are different. If the spraying pipe device is not adjusted properly, the cutting fluid cannot be sprayed to the required position, resulting in unsatisfactory cooling and liquid-carrying effects and low cutting accuracy. The existing spraying devices are inconvenient to operate during the position adjustment process and cannot accurately control the distance between the spraying pipe and the workpiece to be cut or the wire mesh, which is not conducive to the efficient processing of the wire cutting machine. Summary of the Utility Model

[0005] The embodiments of the present application provide a spraying device and a wire cutting machine, which can adjust the relative position with the workpiece to be cut, ensure the spraying effect on the workpiece to be cut, and are conducive to the efficient processing of the wire cutting machine.

[0006] In a first aspect, the embodiments of the present application provide a spraying device for a wire cutting machine. The spraying device includes a spraying unit and two support units. The spraying unit is used to provide a spraying liquid to the workpiece to be cut; the two support units are used to be installed on the frame of the wire cutting machine; the two support units are respectively used for installing the two ends of the spraying unit; the support unit includes a support member and a position adjustment unit. The support member is used to carry the spraying unit, and the position adjustment unit is used to adjust the relative position between the support member and the workpiece to be cut; wherein, the position adjustment unit includes a first adjustment member, and the first adjustment member is used to drive the support member to move in a first direction when rotating along its own axis, so as to adjust the position of the support member relative to the workpiece to be cut, and the first direction is any one of the horizontal direction or the vertical direction.

[0007] In this solution, when the wire cutting machine cuts the workpiece to be cut, the spraying unit sprays cutting fluid towards the workpiece to be cut to cool the workpiece to be cut. Both ends of the spraying unit are respectively installed on the support members of the two support units, and the support members of the two support units jointly provide a bearing function for the spraying unit. By providing the position adjusting unit in the support unit, the first adjusting member in the position adjusting unit can drive the support member and the spraying unit to move in the first direction while rotating along its own axis, realizing the position adjustment of the spraying unit and the wire mesh of the workpiece to be cut or the wire cutting machine in the first direction, so as to meet the differences in the cutting size requirements of different workpieces to be cut, and make the liquid dropping point of the cutting fluid of the spraying unit always meet the spraying requirements. Moreover, when adjusting the position of the spraying unit, only by controlling the rotation amount of the first adjusting member can the precise adjustment of the position of the spraying unit in the first direction be realized, and the adjustment accuracy is high.

[0008] In some embodiments, the position adjusting unit further includes a first bushing and a first connecting shaft. The first bushing is installed on the frame of the wire cutting machine. The first bushing has a first guiding hole extending along the first direction. The first connecting shaft is movably arranged in the first guiding hole along the first direction, and the support member is connected to the first connecting shaft. The first adjusting member is rotatably installed on the first bushing, and the first connecting shaft is in threaded connection with the first adjusting member. The first adjusting member rotates relative to the first bushing to drive the first connecting shaft to move along the first direction.

[0009] In the above technical solution, the first guiding hole is provided in the first bushing. The first guiding hole provides a guiding function for the sliding of the first connecting shaft. The first adjusting member is in threaded cooperation with the first connecting shaft, and the first adjusting member is rotatably installed on the first bushing. By rotating the first adjusting member, under the action of its rotation, by controlling the rotation amount of the first adjusting member, the moving amount of the first connecting shaft in the first guiding hole along the first direction can be precisely controlled, so as to realize the precise adjustment of the position of the spraying unit in the first direction.

[0010] In some embodiments, the position adjusting unit further includes a first limit screw. The first limit screw is in threaded cooperation with the first bushing. One end of the first limit screw is configured to extend into the first guiding hole and abut against the outer wall of the first connecting shaft to limit the movement of the first connecting shaft and the first bushing.

[0011] In the above technical solution, through the setting of the first limit screw, since the first limit screw is in threaded fit with the first bushing, when the position of the spraying unit is adjusted in place, by rotating the first limit screw, the first limit screw can approach the first connecting shaft and abut against the outer wall of the first connecting shaft, providing a locking function for the first connecting shaft, fixing the position of the first connecting shaft, and reducing the phenomenon of position deviation of the spraying unit during operation. When the position of the spraying unit needs to be adjusted, loosen the first limit screw. After the first connecting shaft loses its locking function in this way, the position of the spraying unit can be adjusted through the first adjusting member.

[0012] In some embodiments, the cross-sectional shape of the first connecting shaft is circular, and a first limit groove extending in the first direction is provided on the outer wall of the first connecting shaft. The first limit screw is used to abut and cooperate with the first limit groove to limit the movement of the first connecting shaft relative to the first bushing.

[0013] In the above technical solution, since the cross-sectional shape of the first connecting shaft is circular, when the first adjusting member rotates to drive the first connecting shaft to move, the first connecting shaft may follow and rotate. By providing a first limit groove extending in the first direction on the outer wall of the first connecting shaft, the first limit screw is inserted into the first limit groove. Under the plugging and limiting action of the first limit screw and the first limit groove, the first connecting shaft will not rotate following the first adjusting member, thus playing an anti-rotation function. When the first limit screw abuts against the bottom wall of the first limit groove, then the first connecting shaft will not slide in the first guiding hole in the first direction, thereby locking the position of the first connecting shaft.

[0014] In some embodiments, the position adjusting unit further includes a second adjusting assembly. The second adjusting assembly is disposed between the first connecting shaft and the support member. The second adjusting assembly is used to drive the support member to move in the second direction, and the second direction is the vertical direction, and the first direction is perpendicular to the second direction.

[0015] In the above technical solution, by providing the second adjusting assembly, which is disposed between the first connecting shaft and the support member, the second adjusting assembly can drive the support member to move in the second direction. In this way, the spraying unit can achieve position adjustment in two directions, namely the first direction and the second direction. The position adjustment range of the spraying unit is larger, the applicable range is wider, and it can better meet the position adjustment requirements of the spraying unit.

[0016] In some embodiments, the second adjustment assembly includes a second bushing, a second connecting shaft, and a second adjustment member. The second bushing is connected to the first connecting shaft, and the second bushing has a second guiding hole extending along the second direction; the second connecting shaft is movably disposed in the second guiding hole along the second direction, and the support member is connected to the second connecting shaft; the second adjustment member is rotatably mounted at one end of the second bushing, the second adjustment member is threadedly connected to the second connecting shaft, and the second adjustment member rotates relative to the second bushing to drive the second connecting shaft to move along the second direction.

[0017] In the above technical solution, a second guiding hole is provided on the second bushing, and the second guiding hole provides a guiding function for the sliding of the second connecting shaft. The second adjustment member is disposed on the second bushing, and the second adjustment member is in threaded cooperation with the second connecting shaft. The second adjustment member is rotatably mounted on the second bushing. By rotating the second adjustment member, under its rotation effect, by controlling the rotation amount of the second adjustment member, the movement amount of the second connecting shaft in the second guiding hole along the second direction can be accurately controlled, so as to achieve precise adjustment of the position of the spraying unit in the second direction.

[0018] In some embodiments, the second adjustment assembly further includes a second limit screw, the second limit screw is in threaded cooperation with the second bushing, and one end of the second limit screw is configured to extend into the second guiding hole and abut against the outer wall of the second connecting shaft to limit the movement of the second connecting shaft and the second bushing.

[0019] In the above technical solution, due to the setting of the second limit screw, since the second limit screw is in threaded cooperation with the second bushing, when the position of the spraying unit in the second direction is adjusted in place, by tightening the second limit screw, the second limit screw can approach the second connecting shaft and abut against the outer wall of the second connecting shaft, providing a locking function for the second connecting shaft, fixing the position of the spraying unit, and making the spraying unit more stable. And when it is necessary to adjust the position of the spraying unit in the second direction, loosen the second limit screw. After the second connecting shaft loses the locking function in this way, the position of the spraying unit in the second direction can be adjusted through the second adjustment member.

[0020] In some embodiments, the cross-sectional shape of the second connecting shaft is circular, and a second limit groove extending along the second direction is provided on the outer wall of the second connecting shaft. The second limit screw is used to abut and cooperate with the second limit groove to limit the movement of the second connecting shaft relative to the second bushing.

[0021] In the above technical solution, since the cross-sectional shape of the second connecting shaft is circular, the second connecting shaft may rotate with the rotation of the second adjusting member when the second adjusting member drives the second connecting shaft to move. By providing a second limiting groove extending along the second direction on the outer wall of the second connecting shaft, the second limiting screw is inserted into the second limiting groove. Under the limiting effect of the insertion of the second limiting screw and the second limiting groove, the second connecting shaft will not rotate with the second adjusting member, thus playing an anti-rotation function. When the second limiting screw abuts against the bottom wall of the second limiting groove, the second connecting shaft will not slide along the second direction in the second guiding hole.

[0022] In some embodiments, the support member includes a first support portion and a second support portion. The corresponding end of the spraying unit can be selectively installed on the first support portion or the second support portion. Along the second direction, the second support portion is farther from the workpiece to be cut than the first support portion. The second direction is the vertical direction, and the second direction is perpendicular to the first direction.

[0023] In the above technical solution, through the arrangement of the first support portion and the second support portion on the support member, both the first support portion and the second support portion can bear the end of the spraying assembly. In this way, when installing the spraying unit, the corresponding end of the spraying unit is installed on the first support portion to realize the spraying of the cutting fluid towards the workpiece to be cut. When it is necessary to stop the machine to operate on the wire mesh or the workpiece to be cut (silicon rod) on the wire cutting machine, since the second support portion is farther from the workpiece to be cut than the first support portion in the vertical direction, after removing the spraying unit from the first support portion and placing it on the second support portion, the staff can operate on the wire mesh or the workpiece to be cut (silicon rod) on the wire cutting machine. Therefore, due to the arrangement of the second support portion, the second support portion can be used as a temporary storage station for the spraying unit. When the staff disassemble the spraying unit, they do not need to disassemble the water inlet pipeline, nor do they need to take the spraying unit out of the cutting room to cause the problem of dripping and polluting the surrounding environment. They only need to remove the spraying unit from the first support portion and place it on the second support portion far from the workpiece to be cut.

[0024] In some embodiments, the first support portion has a first positioning groove for bearing the end of the spraying unit, and the second support portion has a second positioning groove for bearing the end of the spraying unit; the bracket unit further includes a pressing member, and the pressing member is used to provide a pressing force to the end of the spraying unit to press and position the end of the spraying unit in the first positioning groove and / or the second positioning groove.

[0025] In the above technical solution, the end of the spraying unit is placed on the first positioning groove or the second positioning groove on the support member. The first positioning groove or the second positioning groove can provide a bearing and positioning function for the end of the spraying unit, so that the spraying unit can be placed on the first positioning groove or the second positioning groove of the bracket unit relatively stably;

[0026] In order to further improve the stability of the spray unit mounted on the support unit, a pressing member is provided. The pressing member can provide a pressing force to the end of the spray unit, pressing the end of the spray unit into the first positioning groove and / or the second positioning groove. In this way, under the action of the pressing force of the pressing member, the end of the spray unit is not likely to be displaced or even separated from the first support portion or the second support portion, improving the installation stability of the spray unit on the support unit.

[0027] In some embodiments, the cross-sectional shapes of the first positioning groove and the second positioning groove in the two support units are at least the same for at least two of them.

[0028] In some embodiments, the two support units are respectively a first support unit and a second support unit. The cross-sectional shapes of the first positioning groove and the second positioning groove in the first support unit are V-shaped, and the cross-sectional shapes of the first positioning groove and the second positioning groove in the second support unit are semi-circular.

[0029] In the above technical solution, the setting of the semi-circular positioning groove in the second support unit can limit the movement of the corresponding end of the spray unit. By adopting a V-shaped first positioning groove and second positioning groove in the first support unit, the opening of the V-shaped positioning groove is larger, which is conducive to the installation of the end of the spray unit into the first positioning groove or the second positioning groove, reducing the installation difficulty of the spray unit.

[0030] In some embodiments, water-permeable holes are provided in the first positioning groove and / or the second positioning groove of the first support unit.

[0031] In the above technical solution, by providing water-permeable holes in the first positioning groove or the second positioning groove, the water-permeable holes can drain the accumulated water in the V-shaped groove, reducing the problem of silicon powder accumulation on the support during the cutting of the workpiece to be cut.

[0032] In some embodiments, the spray unit includes a first spray assembly and a second spray assembly. The first spray assembly and the second spray assembly are connected. The two support units are respectively used for installing the two ends of the second spray assembly; the first spray assembly is used for spraying towards the workpiece to be cut during the retraction process after the wire cutting machine completes cutting, and the second spray assembly is used for spraying during the cutting of the workpiece to be cut by the wire cutting machine.

[0033] In the above technical solution, by including a first spray assembly and a second spray assembly in the spray unit, when the wire cutting machine cuts the workpiece to be cut, the first spray assembly can spray towards the workpiece to be cut during the retraction process after the wire cutting machine completes cutting, and the second spray assembly can spray during the cutting of the workpiece to be cut by the wire cutting machine, realizing the function of spraying cutting fluid on the workpiece to be cut.

[0034] In a second aspect, an embodiment of the present application further provides a wire cutting machine, which includes the aforementioned spraying device.

[0035] Other features and advantages of the present application will be described in detail in the subsequent specific implementation section. Description of the Drawings

[0050] Embodiment

[0051] When an online cutting machine is working, it is necessary to spray liquid on the cutting part of the workpiece to be cut to reduce the temperature of the cutting part. Generally, the sprayed liquid is led to a suitable position in the cutting area through a spraying unit to spray the workpiece to be cut. Due to the size differences of the workpieces to be cut, for workpieces of different sizes, the positions where they contact the cutting wire are different. If the spraying unit is not adjusted properly, the cutting fluid cannot be sprayed to the required position, resulting in problems such as unsatisfactory cooling and liquid-carrying effects and low cutting accuracy. The existing spraying devices are inconvenient to operate during the position adjustment process, and cannot accurately control the distance between the spraying pipe and the workpiece to be cut or the cutting wire mesh, which is not conducive to the efficient processing of the wire cutting machine.

[0052] In view of this, the embodiment of the present application provides a spraying device for a wire cutting machine. Please refer to Figure 1 and Figure 2 , the spraying device 100 includes a spraying unit 30 and two support units 10. The spraying unit 30 is used to provide spraying liquid to the workpiece to be cut; the two support units 10 are used to be installed on the frame of the wire cutting machine; the two support units 10 are respectively used for installing both ends of the spraying unit 30; the support unit 10 includes a support member 13 and a position adjustment unit 20. The support member 13 is used to carry the spraying unit 30, and the position adjustment unit 20 is used to adjust the relative position between the support member 13 and the workpiece to be cut; wherein, the position adjustment unit 20 includes a first adjustment member 210. The first adjustment member 210 is used to drive the support member 13 to move in the first direction X when rotating along its own axis, so as to adjust the position of the support member 13 relative to the workpiece to be cut, and the first direction X is any one of the horizontal direction or the vertical direction.

[0053] In this solution, when the wire cutting machine cuts the workpiece to be cut, the spraying unit 30 sprays cutting fluid towards the workpiece to be cut to achieve the cooling function for the workpiece to be cut. Both ends of the spraying unit 30 are respectively installed on the supporting members 13 of the two bracket units 10, and the supporting members 13 of the two bracket units 10 jointly provide the bearing function for the spraying unit 30. Through the setting of the position adjusting unit 20 in the bracket unit 10, the first adjusting member 210 in the position adjusting unit 20 can drive the supporting member 13 and the spraying unit 30 to move in the first direction X while rotating along its own axis, so as to realize the position adjustment of the spraying unit 30 and the wire mesh of the wire cutting machine or the workpiece to be cut in the first direction X, thereby being able to meet the differences in the cutting size requirements of different workpieces to be cut, and enabling the liquid dropping point of the cutting fluid of the spraying unit 30 to always meet the spraying requirements. Moreover, when adjusting the position of the spraying unit 30, only by controlling the rotation amount of the first adjusting member 210, the precise position adjustment of the spraying unit 30 in the first direction X can be realized, and the adjustment accuracy is high.

[0054] Among them, there are various ways to adjust the rotation of the first adjusting member 210. For example, the way of the screw-nut pair mechanism can be adopted. The position adjusting unit 20 includes a mounting plate. The first adjusting member is a screw, and the first adjusting member is rotatably installed on the mounting plate. The supporting member is a nut, and the supporting member 13 is in threaded cooperation with the first adjusting member 210. The supporting member 13 is slidably matched with the mounting plate along the first direction X to prevent the supporting member 13 from rotating following the first adjusting member 210. In this way, by rotating the first adjusting member 210, the supporting member 13 can be driven to move axially on the first adjusting member 210, so as to realize the precise position adjustment of the spraying unit 30 in the first direction X. Of course, the first adjusting member 210 can also be adjusted in other installation ways.

[0055] In some embodiments, please refer to Figure 4 and Figure 5, the position adjusting unit 20 further includes a first bushing 211 and a first connecting shaft 212. The first bushing 211 is installed on the frame of the wire cutting machine. The first bushing 211 has a first guiding hole extending along the first direction X. The first connecting shaft 212 is movably arranged in the first guiding hole along the first direction X, and the support member 13 is connected to the first connecting shaft 212. The first adjusting member 210 is rotatably installed on the first bushing 211. The first connecting shaft 212 is threadedly connected to the first adjusting member 210. The first adjusting member 210 rotates relative to the first bushing 211 to drive the first connecting shaft 212 to move along the first direction X. By providing the first guiding hole in the first bushing 211, the first guiding hole provides a guiding function for the sliding of the first connecting shaft 212. The first adjusting member 210 is in threaded cooperation with the first connecting shaft 212, and the first adjusting member 210 is rotatably installed on the first bushing 211. By rotating the first adjusting member 210, under the action of its rotation, by controlling the rotation amount of the first adjusting member 210, the moving amount of the first connecting shaft 212 in the first guiding hole along the first direction X can be accurately controlled, so as to accurately adjust the position of the spraying unit 30 in the first direction X.

[0056] Wherein, the first bushing 211 is fixed on the first mounting plate 23. The first mounting plate 23 is provided with a screw hole. The first bushing 211 is connected to the frame of the wire cutting machine through the first mounting plate 23. The first adjusting member 210 is an adjusting screw. The first adjusting member 210 is rotatably installed on the first bushing 211 and is limited by the first flange 214. A flange portion protrudes from the first adjusting member 210. The first flange 214 provides a blocking effect on the flange portion to prevent the first adjusting member 210 from separating from the first bushing 211. In addition, a first sealing ring 215 can be provided between the first bushing 211 and the first adjusting member 210. The first sealing ring 215 can reduce the entry of cutting fluid into the position adjusting unit 20 during the adjustment of the first adjusting member 210 or during the operation of the wire cutting machine.

[0057] Of course, the first adjusting member 210 can also be rotatably installed on the first bushing 211 through a bearing, so that by rotating the first adjusting member 210, the first connecting shaft 212 is driven to move in the first guiding hole of the first bushing 211.

[0058] In some embodiments, the position adjusting unit 20 further includes a first limit screw 213. The first limit screw 213 is in threaded cooperation with the first bushing 211. One end of the first limit screw 213 is configured to extend into the first guiding hole and abut against the outer wall of the first connecting shaft 212 to limit the movement of the first connecting shaft 212 and the first bushing 211. Through the arrangement of the first limit screw 213, since the first limit screw 213 is in threaded cooperation with the first bushing 211, after the position of the spraying unit 30 is adjusted in place, by rotating the first limit screw 213, the first limit screw 213 can approach the first connecting shaft 212 and abut against the outer wall of the first connecting shaft 212, providing a locking function for the first connecting shaft 212, fixing the position of the first connecting shaft 212, and reducing the phenomenon of position deviation of the spraying unit 30 during operation. When the position of the spraying unit 30 needs to be adjusted, loosen the first limit screw 213. In this way, after the first connecting shaft 212 loses the locking function, the position of the spraying unit 30 can be adjusted through the first adjusting member 210.

[0059] Wherein, the cross-sectional shape of the first connecting shaft 212 can be square, triangular or circular, etc. When the cross-sectional shape of the first connecting shaft 212 is square, then the hole shape of the first guiding hole is also a square hole. When the first adjusting member 210 drives the first connecting shaft 212 to slide in the first guiding hole, the first connecting shaft 212 will not rotate following the first adjusting member 210.

[0060] When the cross-sectional shape of the first connecting shaft 212 is circular, then an anti-rotation component needs to be correspondingly arranged on the first bushing 211 to prevent the first connecting shaft 212 from rotating following the first adjusting member 210 by using the anti-rotation component.

[0061] In some embodiments, the cross-sectional shape of the first connecting shaft 212 is circular, and a first limit groove extending along the first direction X is provided on the outer wall of the first connecting shaft 212. The first limit screw 213 is used to abut and cooperate with the first limit groove to limit the movement of the first connecting shaft 212 relative to the first bushing 211. Since the cross-sectional shape of the first connecting shaft 212 is circular, when the first adjusting member 210 rotates to drive the first connecting shaft 212 to move, there may be a phenomenon that the first connecting shaft 212 rotates following. By providing a first limit groove extending along the first direction X on the outer wall of the first connecting shaft 212, the first limit screw 213 is inserted into the first limit groove. Under the plugging and limiting action of the first limit screw 213 and the first limit groove, the first connecting shaft 212 will not rotate following the first adjusting member 210, thus playing an anti-rotation function. When the first limit screw 213 abuts against the bottom wall of the first limit groove, then the first connecting shaft 212 will not slide along the first direction X in the first guiding hole, thereby locking the position of the first connecting shaft 212.

[0062] In some embodiments, please refer toFigure 4 and Figure 6 The position adjusting unit 20 further includes a second adjusting assembly 22. The second adjusting assembly 22 is disposed between the first connecting shaft 212 and the support member 13. The second adjusting assembly 22 is configured to drive the support member 13 to move in the second direction Y, and the second direction Y is the vertical direction. The first direction X is perpendicular to the second direction Y. By providing the second adjusting assembly 22, which is disposed between the first connecting shaft 212 and the support member 13, the second adjusting assembly 22 can drive the support member 13 to move in the second direction Y. In this way, the spraying unit 30 can achieve position adjustment in two directions, namely the first direction X and the second direction Y. The position adjustment range of the spraying unit 30 is larger, the applicable range is wider, and it can better meet the position adjustment requirements of the spraying unit 30.

[0063] In some embodiments, please refer to Figure 4 and Figure 6 The second adjusting assembly 22 includes a second bushing 221, a second connecting shaft 222, and a second adjusting member 223. The second bushing 221 is connected to the first connecting shaft 212, and the second bushing 221 has a second guiding hole extending along the second direction Y. The second connecting shaft 222 is movably disposed in the second guiding hole along the second direction Y, and the support member 13 is connected to the second connecting shaft 222. The second adjusting member 223 is rotatably mounted at one end of the second bushing 221. The second adjusting member 223 is threadedly connected to the second connecting shaft 222. The second adjusting member 223 rotates relative to the second bushing 221 to drive the second connecting shaft 222 to move along the second direction Y. By providing the second guiding hole on the second bushing 221, the second guiding hole provides a guiding function for the sliding of the second connecting shaft 222. The second adjusting member 223 is disposed on the second bushing 221, and the second adjusting member 223 is in threaded cooperation with the second connecting shaft 222. The second adjusting member 223 is rotatably mounted on the second bushing 221. By rotating the second adjusting member 223, under the action of its rotation, by controlling the rotation amount of the second adjusting member 223, the movement amount of the second connecting shaft 222 in the second guiding hole along the second direction Y can be accurately controlled, so as to realize the precise adjustment of the position of the spraying unit 30 in the second direction Y.

[0064] Among them, the second adjusting member 223 can be various adjusting mechanisms. For example, the second adjusting member 223 can be a linear driving mechanism such as an adjusting screw, an electric push rod, or a cylinder.

[0065] The second adjusting member 223 is an adjusting screw, which is rotatably mounted on the second bushing 221 and limited by the second flange 225. A flange portion protrudes from the second adjusting member 223, and the second flange 225 provides a blocking effect on the flange portion to prevent the second adjusting member 223 from detaching from the second bushing 221. In addition, a second sealing ring 226 may be provided between the second bushing 221 and the second adjusting member 223. The second sealing ring 226 can reduce the entry of cutting fluid into the second adjusting assembly 22 during the adjustment of the second adjusting member 223 or during the operation of the wire cutting machine. Of course, the second adjusting member 223 may also be rotatably mounted on the second bushing 221 through a bearing.

[0066] In some embodiments, the second adjusting assembly 22 further includes a second limit screw 224, which is in threaded cooperation with the second bushing 221. One end of the second limit screw 224 is configured to extend into the second guiding hole and abut against the outer wall of the second connecting shaft 222 to limit the movement of the second connecting shaft 222 and the second bushing 221. Through the arrangement of the second limit screw 224, since the second limit screw 224 is in threaded cooperation with the second bushing 221, when the position of the spraying unit 30 in the second direction Y is adjusted in place, by tightening the second limit screw 224, the second limit screw 224 can approach the second connecting shaft 222 and abut against the outer wall of the second connecting shaft 222 to provide a locking function for the second connecting shaft 222, so that the position of the spraying unit 30 is fixed and the stability of the spraying unit 30 is higher. When the position of the spraying unit 30 in the second direction Y needs to be adjusted, loosen the second limit screw 224. After the second connecting shaft 222 loses the locking function in this way, the position of the spraying unit 30 in the second direction Y can be adjusted through the second adjusting member 223.

[0067] Among them, the cross-sectional shape of the second connecting shaft 222 can be square, triangular or circular, etc. When the cross-sectional shape of the second connecting shaft 222 is square, the hole shape of the second guiding hole is also a square hole. When the second adjusting member 223 drives the second connecting shaft 222 to slide in the second guiding hole, the second connecting shaft 222 will not rotate following the second adjusting member 223. When the cross-sectional shape of the second connecting shaft 222 is circular, an anti-rotation component needs to be correspondingly provided on the second bushing 221 to prevent the second connecting shaft 222 from rotating following the second adjusting member 223.

[0068] In some embodiments, the cross-sectional shape of the second connecting shaft 222 is circular. A second limiting groove extending along the second direction Y is provided on the outer wall of the second connecting shaft 222. The second limiting screw 224 is used to abut and cooperate with the second limiting groove to limit the movement of the second connecting shaft 222 relative to the second bushing 221. Since the cross-sectional shape of the second connecting shaft 222 is circular, when the second adjusting member 223 rotates to drive the second connecting shaft 222 to move, the phenomenon of the second connecting shaft 222 rotating along with it may occur. By providing a second limiting groove extending along the second direction Y on the outer wall of the second connecting shaft 222, the second limiting screw 224 is inserted into the second limiting groove. Under the insertion and limiting action of the second limiting screw 224 and the second limiting groove, the second connecting shaft 222 will not rotate along with the second adjusting member 223, thus playing an anti-rotation function. When the second limiting screw 224 abuts against the bottom wall of the second limiting groove, the second connecting shaft 222 will not slide along the second direction Y in the second guiding hole.

[0069] The second limiting groove is provided on the outer wall of the second connecting shaft 222 and extends along the second direction Y. The two groove side walls of the second limiting groove can contact the opposite sides of the second limiting screw 224.

[0070] Certainly, a first universal ball 216 may also be provided on the first bushing 211. The spherical surface of the first universal ball 216 is located in the first guiding hole. The first universal ball 216 contacts the outer wall of the first connecting shaft 212. The first universal ball 216 can play a guiding role in the movement of the first connecting shaft 212, guiding the first connecting shaft 212 to move in the first guiding hole. A second universal ball 227 may also be provided on the second bushing 221. The spherical surface of the second universal ball 227 is located in the second guiding hole. The second universal ball 227 contacts the outer wall of the second connecting shaft 222, and can play a guiding role in the movement of the second connecting shaft 222, guiding the second connecting shaft 222 to move in the second guiding hole.

[0071] In some embodiments, please refer to Figure 1 and Figure 3, the support member 13 includes a first support portion 131 and a second support portion 132. The corresponding end of the spraying unit 30 is selectively mounted on the first support portion 131 or the second support portion 132. Along the second direction Y, the second support portion 132 is farther from the workpiece to be cut than the first support portion 131. The second direction Y is the vertical direction, and the second direction Y is perpendicular to the first direction X. Through the arrangement of the first support portion 131 and the second support portion 132 on the support member 13, both the first support portion 131 and the second support portion 132 can bear the end of the spraying assembly. In this way, when installing the spraying unit 30, the corresponding end of the spraying unit 30 is installed on the first support portion 131 to realize the spraying of the cutting fluid towards the workpiece to be cut. When it is necessary to stop the machine to operate on the wire mesh or the workpiece to be cut (silicon rod) on the wire cutting machine, since the second support portion 132 is farther from the workpiece to be cut than the first support portion 131 in the vertical direction, after removing the spraying unit 30 from the first support portion 131 and placing it on the second support portion 132, the staff can operate on the wire mesh or the workpiece to be cut (silicon rod) on the wire cutting machine. Therefore, due to the arrangement of the second support portion 132, the second support portion 132 can be used as a temporary storage station for the spraying unit 30. When the staff disassembles the spraying unit 30, they do not need to disassemble the water inlet pipeline, nor do they need to take the spraying unit 30 out of the cutting chamber, which may cause dripping and polluting the surrounding environment. They only need to remove the spraying unit 30 from the first support portion 131 and place it on the second support portion 132 far from the workpiece to be cut.

[0072] In some embodiments, please refer to Figure 3, the first support portion 131 is provided with a first positioning groove 1311 for bearing the end of the spraying unit 30, and the second support portion 132 is provided with a second positioning groove 1321 for bearing the end of the spraying unit 30; the bracket unit 10 further includes a pressing member 14, and the pressing member 14 is used to provide a pressing force to the end of the spraying unit 30 to press and position the end of the spraying unit 30 in the first positioning groove 1311 and / or the second positioning groove 1321. The end of the spraying unit 30 is placed on the first positioning groove 1311 or the second positioning groove 1321 provided on the support member 13. The first positioning groove 1311 or the second positioning groove 1321 can provide a bearing function for the end of the spraying unit 30, so that the spraying unit 30 can be placed on the first positioning groove 1311 or the second positioning groove 1321 of the bracket unit 10 relatively stably. In order to further improve the stability of the spraying unit 30 installed on the bracket unit 10, by providing the pressing member 14, the pressing member 14 can provide a pressing force to the end of the spraying unit 30 and press the end of the spraying unit 30 into the first positioning groove 1311 and / or the second positioning groove 1321. In this way, under the action of the pressing force of the pressing member 14, the end of the spraying unit 30 is not likely to be displaced or even separated from the first support portion 131 or the second support portion 132, improving the installation stability of the spraying unit 30 on the bracket unit 10.

[0073] Among them, in the same bracket unit 10, the number of the pressing members 14 can be set to one, two, three, etc. That is, the pressing member 14 can be provided on one side of the first positioning groove 1311 or on one side of the second positioning groove 1321. Of course, it can also be that in two bracket units 10, one bracket unit 10 is provided with the pressing member 14 and the other bracket unit 10 is not provided with the pressing member 14. The setting position and number of the pressing members 14 can be determined according to the actual situation.

[0074] The pressing member 14 can be various pressing structures. For example, the pressing member 14 can be a pressing cylinder, a hydraulic cylinder or an electric push rod and other pressing structures.

[0075] In some embodiments, the cross-sectional shapes of the first positioning groove 1311 and the second positioning groove 1321 in the two bracket units 10 are at least the same in two of them.

[0076] It can be understood that the cross-sectional shapes of the first positioning groove 1311 and the second positioning groove 1321 in the two bracket units 10 can be completely the same or partially the same, and can be specifically determined according to the actual situation.

[0077] In addition, the cross-sectional shape of the first positioning groove 1311 or the second positioning groove 1321 can be various. For example, the cross-sectional shape of the first positioning groove 1311 or the second positioning groove 1321 can be V-shaped, or semi-circular or square, etc. The cross-sectional shape of the first positioning groove 1311 or the second positioning groove 1321 can be determined according to the actual situation.

[0078] In some embodiments, the two bracket units 10 are respectively a first bracket unit 11 and a second bracket unit 12. The cross-sectional shapes of the first positioning groove 1311 and the second positioning groove 1321 in the first bracket unit 11 are V-shaped, and the cross-sectional shapes of the first positioning groove 1311 and the second positioning groove 1321 in the second bracket unit 12 are semi-circular. The setting of the semi-circular positioning groove in the second bracket unit 12 can limit the movement of the corresponding end of the spraying unit 30. By adopting the V-shaped first positioning groove 1311 and the second positioning groove 1321 in the first bracket unit 11, the opening of the V-shaped positioning groove is larger, which is beneficial to the installation of the end of the spraying unit 30 into the first positioning groove 1311 or the second positioning groove 1321, reducing the installation difficulty of the spraying unit 30.

[0079] Optionally, the pressing member 14 is arranged on the first bracket unit 11. When the end of the spraying unit 30 is placed in the first positioning groove 1311 of the first bracket unit 11, since the first positioning groove 1311 is V-shaped, the end of the spraying unit 30 may tend to displace in the first positioning groove 1311. Therefore, under the action of the pressing member 14, the end of the spraying unit 30 can be firmly held against the first positioning groove 1311 to ensure the installation stability of the spraying unit 30.

[0080] In some embodiments, as Figure 4 shown, a water permeable hole 133 is provided on the first positioning groove 1311 and / or the second positioning groove 1321 of the first bracket unit 11. By providing the water permeable hole 133 on the first positioning groove 1311 or the second positioning groove 1321, the water permeable hole 133 can drain the accumulated water in the V-shaped groove, reducing the problem of silicon powder accumulation on the support 13 during the cutting of the workpiece to be cut.

[0081] In some embodiments, please refer to Figure 1, the spraying unit 30 includes a first spraying component 31 and a second spraying component 32. The first spraying component 31 and the second spraying component 32 are connected. Two bracket units 10 are respectively used for installing the two ends of the second spraying component 32. The first spraying component 31 is used to spray towards the workpiece to be cut during the retraction process after the wire cutting machine finishes cutting. The second spraying component 32 is used to spray during the cutting of the workpiece to be cut by the wire cutting machine. By including the first spraying component 31 and the second spraying component 32 in the spraying unit 30, when the wire cutting machine performs cutting operations on the workpiece to be cut, the first spraying component 31 can spray towards the workpiece to be cut during the retraction process after the wire cutting machine finishes cutting, and the second spraying component 32 can spray during the cutting of the workpiece to be cut by the wire cutting machine, realizing the cutting fluid spraying function for the workpiece to be cut.

[0082] Among them, the first spraying component 31 includes a first spray pipe 311, a first liquid inlet 312, and a plurality of first nozzles 313. The plurality of first nozzles 313 are arranged at intervals on the first spray pipe 311 and communicate with the inner cavity of the first spray pipe 311. The first liquid inlet 312 is communicated with the water inlet pipeline and is used to provide cutting fluid to the inner cavity of the first spray pipe 311, and then spray out from the plurality of first nozzles 313 on the first spray pipe 311. The second spraying component 32 includes a second spray pipe 321, a second liquid inlet, and a plurality of second nozzles 322. The plurality of second nozzles 322 are arranged at intervals on the second spray pipe 321 and communicate with the inner cavity of the second spray pipe 321. The second liquid inlet is communicated with the water inlet pipeline and is used to provide cutting fluid to the inner cavity of the second spray pipe 321, and then spray out from the plurality of second nozzles 322 on the second spray pipe 321.

[0083] The embodiment of the present application also provides a wire cutting machine, and the wire cutting machine includes the aforementioned spraying device. The spraying device sprays cutting fluid onto the workpiece to be cut in the cutting area on the wire cutting machine.

[0084] Please refer to Figure 7 , when using the spraying device 100 to spray cutting fluid onto the workpiece to be cut in the cutting area on the wire cutting machine, the number of the spraying devices 100 can be set to two groups. The two groups of spraying devices 100 cooperate with each other to spray both sides of the workpiece to be cut simultaneously.

[0085] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.

[0086] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
