[0043] Figure 1 is a schematic structural diagram of a measuring device according to one embodiment of the utility model, as shown in Figure 1 , and referring to Figure 2 , the utility model embodiment provides a kind of for cutting line measuring device, including main ruler 200, fine adjustment device 400 and measuring jaw 300.The reference end of main ruler 200 is configured to be connected on the side wall 120 of wire cutting machine, and main ruler 200 is perpendicular to the side wall 120 of wire cutting machine.Fine adjustment device 400 includes fine adjustment main body 410 and adjusting device, and fine adjustment main body 410 is slidably connected to main ruler 200 along the length direction of main ruler 200.Measuring jaw 300 is slidably connected to fine adjustment main body 410 along the length direction of main ruler 200, and adjusting device is configured to cause measuring jaw 300 to move along the length direction of main ruler 200 relative to fine adjustment main body 410.

[0044] In the embodiment, the measuring device is installed on the side wall 120 of the wire cutting machine during measurement. The main ruler 200 is used to support the fine adjustment device 400 and the measuring jaw 300, and is connected to the side wall 120 of the wire cutting machine. The fine adjustment device 400 is used to fine adjust the position of the measuring jaw 300. The measuring jaw 300 is used to contact the cutting wire 110 during measurement to express the position of the cutting wire 110. The side wall 120 of the wire cutting machine is selected as the reference surface of the measuring device. When the measuring device is used for measurement, the reference end of the main ruler 200 is connected to the side wall 120 of the wire cutting machine, the position of the measuring jaw 300 is adjusted, the fine adjustment main body is fixed, and then the relative position of the measuring jaw 300 and the fine adjustment main body 410 is fine adjusted by using the adjusting device, that is, the position of the measuring jaw 300 is fine adjusted. The measuring jaw 300 is abutted against the cutting wire 110, and the position of the measurement point at this time is read. When the measurement is finished, the measuring device can be removed from the side wall 120 of the wire cutting machine to prevent the measuring device from interfering with the operation of the wire cutting machine. According to the distance between the different positions of the cutting wire 110 and the reference surface, the number of slotting of the cutting wire 110 is determined, and then whether the slotting arrangement of the cutting wire 110 meets the preset standard is judged. The position of the slotting arrangement of the cutting wire 110 can also be adjusted according to the measured distance to realize efficient slotting arrangement of the cutting wire 110 in the wire cutting machine. The measuring device can quickly and accurately measure the size of the slotting arrangement of the cutting wire 110 net, effectively solving the problem that the existing technology cannot efficiently and accurately position the cutting wire 110 in the wire cutting machine. The problem of large fluctuation of the thickness deviation of the cut silicon wafer or high frequency of cutting wire 110 breakage caused by incorrect arrangement of the cutting wire 110 is avoided, and the problem of production loss is further caused.

[0045] Further, since the measuring jaw 300 extends along the length direction perpendicular to the main ruler 200, the contactable range of the measuring jaw 300 and the cutting wire 110 is larger, and the installable position range of the main ruler 200 is larger. The edge of the measuring jaw 300 can abut against the cutting wire 110 without needing to ensure that the main ruler 200 and the cutting wire 110 are in the same plane, and the method of installing the measuring device is simpler.

[0046] Preferably, in some embodiments of the utility model, the cutting wire 110 can be a diamond wire.

Moreover, the main ruler 200 and the base 600 are in a split structure, and the main ruler 200 and the base 600 can be produced separately and then spliced, which reduces the difficulty of production and manufacturing and saves manufacturing cost. Moreover, the split structure is more convenient for maintenance, and the main ruler 200 or the base 600 can be individually repaired after being damaged. Furthermore, the split base 600 is also convenient for the user to carry after being disassembled, which improves the utilization rate and application scenarios.

[0050] Further, in some embodiments of the present application, the main ruler 200 is rotatably connected to the base 600, and the main ruler 200 can rotate relative to the base 600 around the length direction of the main ruler 200.

Since the main ruler 200 is rotatable, the user can conveniently adjust the position of the measurement claw 300, and the positions of multiple cutting lines 110 can be measured, thereby making the measurement of the staggered slot arrangement simpler.

[0052] In some other embodiments of the present application, the main ruler 200 is connected to the base 600, and the base 600 is rotatably arranged on the sidewall 120 of the wire cutting machine, or the base 600 is first rotated around the length direction of the main ruler 200 and then fixedly arranged on the sidewall 120 of the wire cutting machine by a suction cup or the like, that is, the main ruler 200 can rotate relative to the sidewall 120 of the wire cutting machine around the length direction of the main ruler 200.

[0060] Alternatively, in other embodiments of the utility model, the adjusting device comprises a moving member, and the moving member is in transmission connection with the measuring claw 300. The moving member is slidably installed on the fine adjustment main body. A damping member is arranged between the moving member and the fine adjustment main body, and the damping member is a friction pad.

[0061] As shown in the figure, Figure 1 In some embodiments of the utility model, the adjusting device is a fine adjustment stud 420. The fine adjustment stud 420 is rotatably connected to the measuring claw 300, so as to drive only the measuring claw 300 to move relative to the fine adjustment main body 410 by rotating, without rotating the measuring claw 300.

[0062] In the embodiment, the fine adjustment main body 410 is in sliding connection with the main ruler 200.

[0066] In this embodiment, the fine adjustment body 410 is sleeved on the main ruler 200, and when sliding, the fine adjustment body 410 can only move along the direction of the main ruler 200, so that the sliding track of the fine adjustment body 410 can be limited, and the measurement accuracy can be ensured.

[0067] Further, in some embodiments of the utility model, the measurement claw 300 is sleeved on the main ruler 200.

[0068] As shown in some embodiments of the utility model, Figure 1 and Figure 2 As shown in some embodiments of the utility model, the measuring device further comprises a first fastening screw 510, the first fastening screw 510 is threadedly connected to the fine adjustment body 410 along the direction perpendicular to the main ruler 200, one end of the first fastening screw 510 penetrates the fine adjustment body 410, and abuts against the main ruler 200.

The fine adjustment screw 420 is rotated to fine adjust the relative position of the measurement claw 300 and the fine adjustment body 410. The first fastening screw 510 can fix the fine adjustment body 410, so that the fine adjustment body 410 is stationary relative to the main ruler 200, which facilitates the subsequent fine adjustment of the measurement claw 300 by using the fine adjustment screw 420 to move the measurement claw 300 relative to the fine adjustment body 410, and then move relative to the main ruler 200, thereby completing the fine adjustment of the measurement claw 300.

[0080] In the embodiment, the measuring claw 300 is first moved to contact the cutting line 110, and then the position of the measuring claw 300 is finely adjusted by the fine adjustment device 400 so that the measuring claw 300 contacts the cutting line 110, the contact sensor outputs the contact signal, and the buzzer emits the audible signal, so that the measurement is avoided in time. Compared with the method in which the user only observes the contact between the measuring claw 300 and the cutting line 110 with the eyes, the method is more accurate, and the operation is also simpler, and the user does not need to repeatedly determine whether the measuring claw 300 contacts the cutting line 110.
