[0038] A driving source 6 is installed at the center of the bottom of the lifting platform 5, and the driving source 6 adopts a motor; the output shaft of the driving source 6 passes through the lifting platform 5 and is connected to the two transmission shafts 8 through the transmission assembly 7.

[0039] The two ends of the lifting platform 5 are respectively installed with adjustment shafts 11 along the width direction, and two adjustment wheels 12 are rotatably installed on the adjustment shafts 11. It should be noted that: the lower part of the cutting line 10 bypasses the adjustment wheel 12, and the setting of the adjustment wheel 12 plays a role in dragging the cutting line 10;

[0040] In detail, the column 2 includes an integrally formed support section 201 and a mounting section 202.

[0041] In detail: the frame 3 includes a frame body 301 and a mounting tube 302 fixed at the corner of the frame body 301, and when the mounting tube 302 is mounted on the upper part of the mounting section 202, the fixing bolt 303 extends into the interior of the mounting tube 302 and is threadedly installed on the mounting section 202, thereby fixing the frame 3; the advantage of this installation method is that the lifting platform 5 can be disassembled, and if the driving source 6 is damaged, it is convenient for maintenance, which brings convenience to the staff.

[0043] When cutting square silicon rods: first place the square silicon rods on the cutting table 44, then start the two lifting structures 4 and the driving source 6 at the same time; when the telescopic ends of the two lifting structures 4 are extended at the same time, the lifting table 5 can be driven to move slowly downward; the output shaft of the driving source 6 drives the main bevel gear 701 to rotate at high speed, and the main bevel gear 701 drives the transmission shaft 8 to move in opposite directions through the two auxiliary bevel gears 702, so that the two transmission shafts 8 respectively drive the driving wheels 9 to rotate in opposite directions, and through the cooperation of the two driving wheels 9, the cutting line 10 can be driven to transmit; when the lifting table 5 moves slowly downward, it can drive the cutting line 10 to move downward, and cut the silicon rods in opposite directions at the same time through the two cutting sections; thereby completing the multi-line cutting work.

[0044] Embodiment 2

[0045] Although the above-mentioned first embodiment can perform multi-wire cutting on square silicon rods; however, the above-mentioned first embodiment cannot adjust the distance between the two cutting sections, and can only cut square silicon rods with the same thickness; it cannot cut square silicon wafers of different thicknesses according to user needs; therefore, in order to solve the above-mentioned technical problems, improvements are made on the basis of the first embodiment;

[0046] An adjusting cylinder 14 is provided at the connection between the adjusting shaft 11 and the adjusting wheel 12, and the adjusting cylinder 14 can move along the axial direction on the adjusting shaft 11; so that the adjusting cylinder 14 can drive the adjusting wheel 12 to move along the axial direction of the adjusting shaft 11; a locking column 15 is symmetrically threadedly installed on the adjusting cylinder 14 with respect to the adjusting wheel 12, and the locking column 15 can be a latch or a bolt; a plurality of locking holes 16 are equidistantly provided on the outer surface of the adjusting shaft 11 along the axial direction, and when the locking column 15 is inserted into the inside of the corresponding locking hole 16, it plays a role in locking the adjusting wheel 12, so as to prevent the adjusting wheel 12 from loosening or shaking during use;

[0047] It should be noted that a bearing 13 is fixed to the outer surface of the adjusting cylinder 14 , and the inner circumferential wall of the adjusting wheel 12 is fixed on the bearing 13 . With the arrangement of the bearing 13 , the cutting line 10 can be more smooth during operation.

[0048] Both ends of the lifting platform 5 are integrally formed with mounting plates 18 along the width direction, and two adjustable drag boxes 19 are respectively installed on each mounting plate 18. It should be noted that: the cutting line 10 is arranged through the drag box 19, and a drag wheel 20 is installed inside the drag box 19 so as to rotate symmetrically about the cutting line 10. The cutting line 10 can be dragged by the two drag wheels 20, so that the cutting line 10 between the drag box 19 and the adjusting wheel 12 is vertically arranged, so as to prevent the cutting line 10 from being separated from the adjusting wheel 12 during operation, thereby improving the stability of the multi-wire cutting device;

[0049] In detail: connecting ears 21 are fixed to both ends of the drag box 19, and a threaded column 22 is fixed to one side of the connecting ear 21, and a first adjustment hole 23 used in conjunction with the threaded column 22 is opened on the mounting plate 18 along the length direction. The drag box 19 can be horizontally adjusted inside the first adjustment hole 23 through the threaded column 22; one end of the threaded column 22 passes through the first adjustment hole 23 and is threadedly installed with a locking nut (not shown in the figure), thereby fastening the drag box 19 to prevent the drag box 19 from shaking during use.

[0050] If the thickness of the square silicon rod cut is to be adjusted: first, the locking column 15 is loosened. After the locking column 15 is detached from the inside of the locking hole 16, the adjusting cylinder 14 can drive the adjusting wheel 12 to move horizontally through the bearing 13; so that the adjusting wheel 12 can drive the cutting line 10 to move horizontally; thereby, the distance between the two cutting sections can be adjusted, and square silicon wafers of different thicknesses can be cut (the principle of square silicon wafer cutting can adopt the above-mentioned embodiment 1); then the locking nut is loosened; the drag box 19 can move on the mounting plate 18 through the threaded column 22; the cutting line 10 can be dragged by the two drag wheels 20 in the drag box 19; so that the cutting line 10 between the drag box 19 and the adjusting wheel 12 is in a horizontal state, avoiding the phenomenon that the cutting line 10 is detached from the adjusting wheel 12 during use, thereby improving the stability of the multi-wire cutting device.

[0051] Embodiment 3

[0052] Although the above-mentioned second embodiment can cut square silicon wafers of different thicknesses, after the distance between the cutting segments is adjusted, the cutting line 10 will inevitably become loose, resulting in poor cutting effect. Therefore, in order to solve the above-mentioned technical problems, further improvements are made on the basis of the second embodiment.

[0053] Adjustment plates 25 are symmetrically arranged at both ends of the lifting platform 5. It should be noted that the middle part of the adjustment plate 25 is rotatably connected to the outer wall of the lifting platform 5; a tensioning roller 26 is rotatably installed between the two adjusting plates 25 in contrast. When the two adjusting plates 25 rotate at the center, the tensioning roller 26 can be driven to move upward and apply upward pressure to the cutting line 10, thereby tightening the cutting line 10 and preventing the cutting line 10 from loosening during use.

[0054] Rotating seats 29 are symmetrically fixed to both ends of the lifting platform 5, and a rotating cylinder 28 is rotatably mounted on the rotating seat 29. A cam 27 connected to the adjusting plate 25 is fixed to the outer surface of the rotating cylinder 28. During the process of the rotating cylinder 28 driving the cam 27 to rotate, one end of the adjusting plate 25 can be squeezed, so that the adjusting plate 25 can rotate at the middle part and drive the tensioning roller 26 to rotate upward; it should be noted that a ratchet 30 is integrally formed at one end of the rotating seat 29, and a locking assembly 31 used in conjunction with the ratchet 30 is fixed to the outer surface of the rotating cylinder 28. Through the cooperation of the ratchet 30 and the locking assembly 31, the rotating cylinder 28 can only rotate in one direction, so as to prevent the tensioning roller 26 from driving the adjusting plate 25 to rotate downward due to gravity.

[0055] The cam 3104 is a substantially parallelogram of the first and second cams, and the first and second cams are configured to be coupled to the first and second cams of the second in-phase motor 3102. The cam 3104 is a substantially parallelogram of the first and second cams, and the first and second cams are configured to be coupled to the first and second cams, and the first and second cams are configured to be coupled to the first and second cams, respectively.

[0056] When tightening the cutting line 10: the rotating cylinders 28 at both ends are rotated clockwise at the same time. During the process of the rotating cylinder 28 driving the cam 27 to rotate, the ratchet 3106 can also be driven to rotate; the protruding part of the cam 27 continues to rotate downward and exerts pressure on the adjustment plate 25, and the two relatively adjusting plates 25 can rotate at the center and move the tensioning roller 26 upward. The tensioning roller 26 can squeeze the cutting line 10 upward, thereby tightening the cutting line 10 and preventing the cutting line 10 from being separated during use. ; During the clockwise rotation of the ratchet 3106, the inclined surface of the ratchet wheel 30 can repeatedly apply pressure upward to the ratchet 3106; the ratchet 3106 drives the hollow rod 3103 to move upward and move upward inside the guide rod 3102; the hollow rod 3103 moves upward through the pressing plate 3104 and applies pressure to the compression spring 3105; then the ratchet 3106 moves in the same manner as above; if the ratchet 3106 is stuck to the corresponding position of the ratchet wheel 30, it plays a role in locking the rotating cylinder 28, preventing the rotating cylinder 28 from rotating counterclockwise;

[0057] If the cutting line 10 is to be loosened: the pressure plate 3104 is swung upward; the pressure plate 3104 drives the hollow rod 3103 to move upward and applies pressure to the compression spring 3105; the hollow rod 3103 can drive the ratchet 3106 to move upward and disengage from the ratchet 30, and then the rotating cylinder 28 can be rotated counterclockwise, and the protruding part of the cam 27 slowly loses the squeezing force on the adjustment plate 25; the tensioning roller 26 can rotate downward due to gravity, thereby playing the role of loosening the cutting line 10.

[0058] Embodiment 4

[0059] Although the above-mentioned embodiments can adjust the tightness of the cutting wire 10 and cut square silicon wafers of different thicknesses, the cutting wire 10 will inevitably heat up during long-term operation, which affects the service life of the cutting wire 10. Therefore, in order to solve the above-mentioned technical defects, further improvements can be made on the basis of the above-mentioned embodiments.

[0060] A hair dryer 32 is installed on the top of the lifting platform 5, and the blowing end of the hair dryer 32 extends to the lower part of the lifting platform 5 and is installed with a plurality of air inlet pipes 33. The air outlet ends of the plurality of air inlet pipes 33 are sealed and connected to the same heat sink 34. It should be noted that: the interior of the heat sink 34 is a hollow structure; the interior of the heat sink 34 is provided with a blowing port 35 connected to the hollow structure along the length direction; when the hair dryer 32 delivers air to the interior of the heat sink 34, the gas in the heat sink 34 can be discharged along the interior of the blowing port 35 and radiate the cutting line 10 Blowing air; plays a role in cooling; avoids the phenomenon of damage to the cutting line 10 during long-term use, and prolongs the service life of the cutting line 10; it should be noted that: the cross-section of the heat sink 34 is set in a "semi-circular ring" shape; so that the lower part of the heat sink 34 can be sleeved on the tensioning roller 26, and a number of limiting grooves are equidistantly provided on the heat sink 34. Through the cooperation of the tensioning roller 26 and the heat sink 34, the limiting groove plays a role in limiting the cutting line 10, preventing the cutting line 10 from being deviated left and right during the operation;

[0061] A guide rail 36 is fixed to the inner side wall of the lifting platform 5 along the length direction, and a sliding seat 37 is slidably installed on the guide rail 36; it should be noted that: first locking bolts 40 are respectively installed on both sides of the sliding seat 37, and a second adjustment hole 41 used in conjunction with the first locking bolt 40 is opened on the guide rail 36 along the length direction. Through the cooperation of the first locking bolt 40 and the second adjustment hole 41, the sliding seat 37 is locked to prevent the sliding seat 37 from moving in the horizontal direction during use;

[0062] A sliding block 38 with an I-shaped cross-section is fixed on the sliding seat 37 in the vertical direction; a lifting rod 39 is installed on the sliding block 38 for sliding up and down, and through the cooperation of the sliding block 38 and the lifting rod 39, the heat sink 34 fixed at the bottom end of the lifting rod 39 can be driven to move up and down; a second locking bolt 42 is threadedly installed on the sliding block 38; and a third adjustment hole 43 is opened in the vertical direction on the lifting rod 39 for use with the second locking bolt 42; through the cooperation of the second locking bolt 42 and the third adjustment hole 43, the lifting rod 39 is locked to prevent the lifting rod 39 from falling downward due to gravity during use.

[0063] If the cutting line 10 is heated up due to long-term operation, two hair dryers 32 can be turned on, and each hair dryer 32 can deliver wind to the inside of several air inlet pipes 33 respectively; the multiple air inlet pipes 33 can deliver wind to the inside of the heat sink 34 respectively, so that the wind in the heat sink 34 can be discharged from the air outlet 35 and blown onto the cutting line 10, thereby playing a role in cooling the cutting line 10; avoiding the cutting line 10 from working when it is hot, reducing the damage of the cutting line 10, and extending the service life.

[0064] During the process of cutting the square silicon rod by the cutting line 10, the cutting line 10 will inevitably deviate, resulting in a comparative deviation of the cutting of the square silicon rod. Therefore, in order to solve this technical defect, it can be used in conjunction with the third embodiment to overcome the technical defect.

[0065] If the cutting line 10 is to be prevented from deviating, first the first locking bolt 40 and the second locking bolt 42 may need to be loosened, and then the heat sink 34 may be adjusted horizontally or vertically according to the position of the tensioning roller 26, so that after the lower part of the heat sink 34 is sleeved on the upper part of the tensioning roller 26, the cutting line 10 can pass through one of the limiting grooves, thereby limiting the cutting line 10 and preventing the cutting line 10 from deviating during use. After the heat sink 34 is adjusted, the first locking bolt 40 and the second locking bolt 42 are tightened again to prevent the heat sink 34 from loosening during use.
