[0022] See also Figures 1 to 3 The double-wire cutting device 100 includes a winding assembly 30 , a first guide assembly 10 and a second guide assembly 20 .

[0023] See also Figures 1 to 3 The winding assembly 30 includes a cutting wire, a drum 31, and a driving mechanism 32 for driving the drum 31 to reciprocate; the cutting wire can be a diamond wire, which is a cutting wire formed by high-strength diamond particles attached to a metal wire, and the metal wire can be a steel wire.

The driving mechanism 32 can drive the drum 31 to rotate so that one end of the cutting wire is released outward, while the other end of the cutting wire is wound. When the driving direction of the driving mechanism 32 changes, the rotation direction of the drum 31 changes, so that one end of the cutting wire is wound, while the other end of the cutting wire is wound outward.

[0024] See also Figures 1 to 3 The first guide assembly 10 includes a first mounting plate 13, a first guide wheel 11 and a second guide wheel 12. The first guide wheel 11 and the second guide wheel 12 are both rotatably mounted on the first mounting plate 13 and are arranged at intervals along a first direction. The first mounting plate 13 is arranged along a vertical direction, and the first direction is along a horizontal direction, which is represented by an X direction. The first guide wheel 11 and the second guide wheel 12 can be rotatably mounted on the first mounting plate 13 through bearings, and the plane determined by the rotation trajectories of the first guide wheel 11 and the second guide wheel 12 is a vertical plane.

The plate surface of the first mounting plate 13 is parallel to the plate surface of the second mounting plate 22. The second mounting plate 22 can be fixedly arranged. The third guide wheel 23 and the fourth guide wheel 24 are both rotatably mounted on the second mounting plate 22 and are arranged at intervals along the first direction. The third guide wheel 23 and the fourth guide wheel 24 can be rotatably mounted on the second mounting plate 22 through bearings, and the plane determined by the rotation trajectories of the third guide wheel 23 and the fourth guide wheel 24 is a vertical plane.

[0026] See also Figures 1 to 3 One end of the cutting line is fixed to the drum 31, and the other end of the cutting line is connected to the first guide wheel 11 and the second guide wheel 12 in sequence, and returns to and wraps around the drum 31, and then extends from the drum 31 to the third guide wheel 23, and is connected to the third guide wheel 23 and the fourth guide wheel 24 in sequence, and then returns to and is fixed on the drum 31 again.

[0027] See also Figures 1 to 3 The portion of the cutting line located between the first guide wheel 11 and the second guide wheel 12 can be used to cut the workpiece. Since the first guide wheel 11 and the second guide wheel 12 are arranged in the horizontal direction, the portion of the cutting line located between the first guide wheel 11 and the second guide wheel 12 is also arranged horizontally and can cut the workpiece. Similarly, the portion of the cutting line located between the third guide wheel 23 and the fourth guide wheel 24 can also be used to cut the workpiece. Since the third guide wheel 23 and the fourth guide wheel 24 are arranged in the horizontal direction, the portion of the cutting line located between the third guide wheel 23 and the fourth guide wheel 24 is also arranged horizontally and can cut the workpiece.

[0028] See also Figures 1 to 3The double-wire cutting device 100 provided in the embodiment of the present application arranges the first guide wheel 11 and the second guide wheel 12 horizontally along the first direction, and then arranges the third guide wheel 23 and the fourth guide wheel 24 horizontally along the first direction, and the driving mechanism 32 drives the roller 31 to rotate reciprocatingly, and the roller 31 reciprocates to reel in and unreel the cutting wire, so that the part of the cutting wire located at the first guide wheel 11 and the second guide wheel 12 and the part of the cutting wire located at the third guide wheel 23 and the fourth guide wheel 24 can reciprocately cut the workpiece at the same time, and double-wire cutting can be performed simultaneously during one cutting process of the workpiece, thereby improving the cutting efficiency.

[0029] It can be understood that the workpiece is fixed on the lifting platform 102, and during the cutting process, the lifting platform 102 drives the workpiece to move vertically upward at the same time, so that the cutting can be carried out smoothly.

[0030] See also Figures 1 to 3 Optionally, the first guide wheel 11 and the second guide wheel 12 are arranged corresponding to the third guide wheel 23 and the fourth guide wheel 24, that is, the first guide wheel 11 and the third guide wheel 23 are arranged at intervals along the second direction and are basically coaxially arranged; the third guide wheel 23 and the fourth guide wheel 24 are arranged at intervals along the second direction and are basically coaxially arranged, the first direction is perpendicular to the second direction, and both are horizontal directions, and the second direction is represented by the Y direction, so that during the cutting process, the cutting line is located at the part of the first guide wheel 11 and the second guide wheel 12, and the cutting line is located at the part of the third guide wheel 23 and the fourth guide wheel 24. The plane determined by the two parts is a horizontal plane, so that the workpiece can be cut at the same time, ensuring that the workpiece is subjected to balanced force and improving the cutting accuracy. In this way, while ensuring the cutting accuracy, the cutting efficiency of the workpiece is improved.

[0031] See also Figures 1 to 3 It can also be understood that crystalline silicon and sapphire are highly rigid and prone to brittle cracking, and the portion of the cutting line located at the first guide wheel 11 and the second guide wheel 12, and the portion of the cutting line located at the third guide wheel 23 and the fourth guide wheel 24 move in the same direction during the cutting process, so that the force direction of the workpiece during the cutting process is consistent and the force is uniform, thereby avoiding the application of additional torque on the workpiece, which may cause torsional brittle cracking of the workpiece.

[0032] See also Figure 3 and Figure 4 Optionally, winding grooves 103 are provided on the circumference of the first guide wheel 11, the second guide wheel 12, the third guide wheel 23 and the fourth guide wheel 24. The winding grooves 103 are annular in structure, and the cross-sectional shape of the winding grooves 103 is V-shaped. The cutting wire part is located in each winding groove 103. Each winding groove 103 can improve the stability of the cutting wire movement and avoid accidental sliding of the cutting wire.

[0033] See also Figure 4 The winding groove 103 on the first guide wheel 11 and the winding groove 103 on the third guide wheel 23 are arranged adjacent to each other, so as to facilitate the driving of the cutting line by the roller 31, so that the cutting line is located at the part between the first guide wheel 11 and the second guide wheel 12, and the cutting line is located at the part between the third guide wheel 23 and the fourth guide wheel 24. The two parts are closely adjacent to each other. When cutting the workpiece, the two cutting parts basically act on the same position of the workpiece, thereby improving the transmission and cutting stability of the roller 31 and ultimately improving the cutting accuracy.

[0034] Optionally, the double-wire cutting device 100 further includes a frame 101 , the winding assembly 30 is fixed on the top of the frame 101 , the second mounting plate 22 is fixed on the side surface of the frame 101 , and the lifting platform 102 is located in the frame 101 and below the drum 31 .

[0035] See also Figures 1 to 3 In some embodiments, the roller 31 has a first fixing hole 311 and a second fixing hole 312 at both ends of the axial direction, and the two ends of the cutting line are fixed to the first fixing hole 311 and the second fixing hole 312 respectively. Corresponding to the first guide wheel 11 and the third guide wheel 23, the first fixing hole 311 and the second fixing hole 312 can both be threaded holes, and screws are set on the first fixing hole 311 and the second fixing hole 312, and then the two ends of the cutting line are connected to the two screws respectively, and the connection method between the cutting line and the screws can be welding. Of course, the two ends of the cutting line can also be directly passed through and fixed to the first fixing hole 311 and the second fixing hole 312 respectively.

[0036] See also Figures 1 to 3 Optionally, a plurality of first fixing holes 311 are arranged at intervals along the circumference of the drum 31, and a plurality of second fixing holes 312 are also arranged at intervals along the circumference of the drum 31. For example, four first fixing holes 311 are arranged at equal intervals along the circumference of the drum 31, and four second fixing holes 312 are arranged at equal intervals along the circumference of the drum 31. The plurality of first fixing holes 311 and the plurality of second fixing holes 312 facilitate the fixation of the cutting line at both ends, thereby improving the convenience of fixing the cutting line.

[0037] See also Figures 1 to 3 In some embodiments, the roller 31 is arranged to slide along the second direction, and the driving mechanism 32 is also used to drive the roller 31 to slide back and forth along the second direction, and the first direction is perpendicular to the second direction.

[0038] Optionally, during the cutting process, the roller 31 is driven to rotate back and forth, and at the same time, the roller 31 is driven to move back and forth in a straight line in the horizontal direction, so that the cutting line can be wound around the roller 31 at different positions during the process of winding and unwinding, thereby avoiding overlapping and knotting of the cutting line on the roller 31. The cutting line is wound around the roller 31 at different positions, thereby avoiding interference between the wound parts of the cutting line, avoiding the falling and wear of diamond abrasives on the cutting line, and improving the reliability of the cutting line.

[0039] Optionally, a spiral groove is provided on the side surface of the drum 31, and the extension path of the spiral groove is along the circumference of the drum 31 and is arranged in a spiral line, so that part of the cutting line wound on the drum 31 is accommodated in the spiral groove. The spiral groove can prevent the cutting line from sliding or slipping relative to the drum 31 during repeated winding and unwinding, thereby avoiding friction and wear between the surface of the drum 31 and the cutting line, improving the reliability of the cutting line and ensuring the cutting efficiency.

[0040] It can be understood that the lifting platform 102 can drive the workpiece to move along the vertical direction and / or the second direction, so as to facilitate the cutting line to perform double-line cutting on the workpiece.

[0041] See also Figures 1 to 3 In some embodiments, the driving mechanism 32 includes a rotating driver 321 slidingly arranged along a first direction and a fixing seat 322 fixedly arranged relative to the rotating driver 321, the fixing seat 322 is provided with a threaded hole, the rotating driver 321 has a first output shaft 323 connected to the roller 31 and a second output shaft 324 with an external thread, and the second output shaft 324 is screwed into the threaded hole.

[0042] See also Figures 1 to 3Optionally, the winding assembly 30 also includes a guide rail 325 and a slider 326 that slidably cooperates with the guide rail 325 and is connected to a driver. The guide rail 325 is located at the top of the frame 101 and two are arranged at intervals. The fixed seat 322 is also fixed to the top of the frame 101; the number of sliders 326 is adapted to the number of guide rails 325, and the two sliders 326 are respectively slidably connected to the two guide rails 325. The length direction of the guide rails 325 is arranged along the second direction. The rotation driver 321 is a dual-axis motor. The first output shaft 323 and the second output shaft 324 are both arranged along the second direction. The first output shaft 323 is used to drive the roller 31 to rotate reciprocatingly. During the rotation process, the second output shaft 324 in turn drives the rotation driver 321 to slide along the guide rail 325, thereby converting the rotational motion of the second output shaft 324 into a linear movement of the rotation driver 321, thereby realizing the linear movement of the roller 31. By continuously changing the rotation direction of the first output shaft 323 and the second output shaft 324, the rotation direction and the linear movement direction of the drum 31 can be adjusted, so that the cutting wire can be continuously wound up and unwound, and the cutting wire is spirally wound around the side surface of the drum 31. The driving mechanism 32 can simultaneously realize the rotation and linear movement of the drum 31, which is conducive to the compactness of the overall structure of the double-wire cutting device 100.

[0043] See also Figures 3 to 5 In some embodiments, the double-wire cutting device 100 also includes a tensioning mechanism 60, which includes a tensioning wheel 61 and a tensioning driver 62 connected to the second mounting plate 22. The tensioning wheel 61 is rotatably connected to the tensioning driver 62 and two tensioning wheels 61 are arranged at intervals along the second direction. The cutting line abuts against the outer edge of the tensioning wheel 61. The tensioning driver 62 is used to adjust the spacing between the two tensioning wheels 61 along the first direction.

[0044] Optionally, the tensioning driver 62 is a double-axis cylinder, which is located inside the frame 101 and mounted on the second mounting plate 22. The two tensioning wheels 61 respectively rotate the two output rods connected to the double-axis cylinder. The distance between the two tensioning wheels 61 can be adjusted through the double-axis cylinder, thereby adjusting the tension of the cutting line in both directions to improve the adjustment efficiency and cutting efficiency.

[0045] It can be understood that when the two tensioning wheels 61 move toward each other, the tension of the cutting line decreases, and when the two tensioning wheels 61 move away from each other, the tension of the cutting line increases.

[0046] See also Figures 3 to 5 In some embodiments, the double-wire cutting device 100 further includes a spacing adjustment mechanism 40 , and the spacing adjustment mechanism 40 is used to adjust the spacing between the first mounting plate 13 and the second mounting plate 22 .

[0047] Optionally, the first mounting plate 13 is slidably arranged relative to the first mounting plate 13 along the second direction. By adjusting the distance between the first mounting plate 13 and the second mounting plate 22, the distance between the cutting line at the two cutting positions of the workpiece can be adjusted, so that the distance between the portion of the cutting line located between the first guide wheel 11 and the second guide wheel 12 and the portion of the cutting line located between the third guide wheel 23 and the fourth guide wheel 24 can be adjusted, and portions of different thicknesses can be cut from the workpiece along the second direction, thereby improving the application range of the double-wire cutting equipment 100.

[0050] See also Figures 3 to 5 It can be understood that by driving the rotary differential head 42 to rotate, the rotary differential head 42 drives the first mounting plate 13 to move relative to the second mounting plate 22 along the second direction. For example, by rotating the rotary differential head 42 forward, the first mounting plate 13 can be moved closer to the second mounting plate 22, and by rotating the rotary differential head 42 backward, the first mounting plate 13 can be moved away from the second mounting plate 22. That is, the rotational motion of the rotary differential head 42 is converted into a linear movement of the first mounting plate 13. This is a prior art and will not be repeated here.
