They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0034] The specific structure of a resin cutting device for crystal rod orientation provided by an embodiment of the present invention and the corresponding technical effects thereof are described in detail below in conjunction with the patent drawings.

[0035] Please refer to Figure 1-Figure 3 A resin cutting device 1 for orienting a crystal rod provided in an embodiment of the present invention includes a machine platform 100, a lifting device 300, an orienting instrument 200, a clamping device 400 and a cutting device 500.

[0036] The machine 100 has a mounting surface 101, and the mounting surface 101 is used to place a resin block 2 bonded with a silicon carbide crystal rod 3, and the silicon carbide crystal rod 3 is bonded to a side of the resin block 2 away from the mounting surface 101, and the resin block 2 has a first end and a second end opposite to each other along its length direction. It should be noted that the silicon carbide crystal rod 3 can be understood as a silicon carbide crystal rod 3 formed by bonding multiple silicon carbide crystal ingots in sequence along their own axis.

[0037] Optionally, in this embodiment, in order to ensure that the resin block 2 can stably install the silicon carbide crystal rod 3, the resin block 2 has a mounting groove, the inner wall of the mounting groove is an arc-shaped inner wall adapted to the outer peripheral surface of the silicon carbide crystal rod 3, and the side of the resin block 2 away from the silicon carbide crystal rod 3 is a plane parallel to the mounting surface 101. Therefore, when the resin block 2 with the silicon carbide crystal rod 3 bonded thereto is placed on the mounting surface 101, the axis of the silicon carbide crystal rod 3 is parallel to the mounting surface 101.

[0038] It should be noted that the axis of the silicon carbide crystal rod 3 refers to the structural axis of the silicon carbide crystal rod 3 , and the above-mentioned parallelism should not be limited to being understood as parallelism in a strict sense, as long as it is roughly parallel.

[0039] The orienter 200 is located above the mounting surface 101 and is used to detect the crystal rod. It is easy to understand that before the silicon carbide crystal rod 3 is cut, the crystal axis direction of the silicon carbide crystal rod 3 needs to be determined by the orienter 200.

[0040] The lifting device 300 is installed on the machine 100 and its driving end can be extended and retracted in the height direction. The lifting device 300 is used to lift one end of the resin block 2 to change the angle between the axis of the silicon carbide crystal rod 3 and the mounting surface 101. In other words, the lifting device 300 can lift the first end or the second end of the resin block 2, thereby changing the inclination angle of the silicon carbide crystal rod 3. Generally, the crystal axis of the silicon carbide crystal rod 3 is different from the structural axis of the silicon carbide crystal rod 3 and is at an angle to the structural axis of the silicon carbide crystal rod 3. Therefore, the lifting device 300 can lift one end of the resin block 2 to change the inclination angle of the silicon carbide crystal rod 3 until the orientation instrument 200 detects the crystal axis of the silicon carbide crystal rod 3, and then the lifting device 300 stops.

[0041] The clamping device 400 is installed on the machine 100 and is located on the mounting surface 101. The clamping device 400 is used to fix the resin block 2. The cutting device 500 is installed on the machine 100 and is located on the mounting surface 101. The cutting device 500 is used to cut from the first end to the second end of the resin block 2 along a preset direction. The preset direction is parallel to the mounting surface 101. The lifting device 300, the orientator 200, the clamping device 400 and the cutting device 500 are communicatively connected.

[0042] When the orientator 200 is detecting the crystal axis of the silicon carbide crystal rod 3, the lifting device 300 stops lifting and the clamping device 400 fixes the resin block 2. At this time, the cutting device 500 can cut from the first end to the second end of the resin block 2 along a preset direction. After the cutting is completed, the resin block 2 is placed on a plane, and the posture of the silicon carbide crystal rod 3 is still in a tilted state. At this time, the tilt direction of the silicon carbide crystal rod 3 is parallel to the crystal axis direction, so that the slicing device can slice the silicon carbide crystal rod 3. Through the cooperation of the lifting device 300, the clamping device 400, the orientator 200 and the cutting device 500, the processing efficiency of polishing the resin after the crystal rod orientation detection can be improved.

[0043] It can be understood that in some optional embodiments, when the orientator 200 detects the crystal axis of the silicon carbide crystal rod 3, when the current of the orientator 200 itself reaches a preset value, it can be determined that the orientator 200 can apply a constant voltage to the silicon carbide crystal rod 3, and by measuring the current value passing through the silicon carbide crystal rod 3, the orientator 200 can obtain the current change information, and the orientator 200 will set a preset current value. When the detected current value reaches this preset value, the inclination direction of the surface silicon carbide crystal rod 3 is in the correct direction.

[0044] In detail, the cutting assembly includes a linear drive member 510 and a cutting assembly. The linear drive member 510 is installed on the machine 100 and is fixedly connected to the cutting assembly. The linear drive member 510 is used to drive the cutting assembly to move along a preset direction. It can be understood that the cutting assembly is used to move in a preset direction driven by the linear drive member 510. During the movement, the cutting assembly is started to cut from the first end to the second end of the resin block 2.

[0045] The linear drive 510 is fixedly mounted on the machine 100. Optionally, the linear drive 510 can be a lead screw motor, and the lead screw nut of the lead screw motor is fixedly connected to the cutting assembly. Of course, in some other optional embodiments, the linear drive 510 can also be other types of drive mechanisms, such as a linear drive motor 520, and a structure of a transmission gear set and a transmission rack, the transmission gear set is transmission-connected to the transmission rack and the drive motor 520, the transmission rack is fixedly connected to the cutting assembly, and the linear drive motor 520 drives the cutting assembly to move in a linear direction through the cooperation of the transmission gear set and the transmission rack.

[0046] It should be noted that, in some embodiments, in order to ensure the stability of the movement of the cutting assembly, the cutting device 500 further includes a guide rail, which is fixedly mounted on the machine platform 100 .

[0047] The cutting assembly includes a drive motor 520 and a cutting member 530 connected to each other, and a linear drive member 510 connected to the drive motor 520. The connection in this embodiment may refer to a direct connection, or an indirect connection may be achieved through other connection structures. For example, the linear drive member 510 may be directly connected to the drive motor 520, or may be connected to the drive motor 520 through a frame.

[0048] Optionally, the cutting member 530 in this embodiment may be a cutting grinding wheel.

[0049] In order to prevent the cutting member 530 from interfering with the clamping device 400 when cutting the resin block 2 , the maximum height dimension of the cutting member 530 is smaller than the minimum height dimension of the clamping end of the clamping device 400 when clamping the resin block 2 .

[0050] Optionally, in some embodiments, the mounting surface 101 is provided with a receiving groove, and the resin block 2 is used to be placed in the receiving groove, and part of the resin block 2 extends out of the receiving groove to be clamped by the clamping device 400. It can be understood that the provision of the receiving groove facilitates the operator to install the resin block 2 in place, and in the receiving groove, the resin block 2 can be limited by the receiving groove to prevent the resin block 2 from moving easily.

[0051] The machine 100 is provided with a matching hole for the driving end of the lifting device 300 to match, and the driving end of the lifting device 300 can extend or retract into the matching hole. The matching hole is located below the resin block 2 and at one end of the resin block 2. It can be understood that when the resin block 2 is placed on the mounting surface 101 and is located above the matching hole, after the resin block 2 is placed on the mounting surface 101, the resin block 2 covers the matching hole. When the driving end of the lifting device 300 extends out of the matching hole, the resin block 2 can be lifted, and one end of the resin block 2 is suspended, thereby changing the inclination angle of the silicon carbide crystal rod 3 bonded to the resin block 2. When the driving end of the lifting device 300 is retracted into the matching hole, the side wall of the resin block 2 away from the silicon carbide crystal rod 3 contacts the mounting surface 101.

[0052] In some optional embodiments, a sinking groove 103 is opened at the bottom of the accommodating groove, wherein in the above-mentioned cutting device 500, the screw and the screw nut in the linear driving member 510 are both located in the sinking groove 103, the driving motor 520 is also located in the sinking groove 103, and the cutting member 530 is located in the accommodating groove and at one end of the resin block 2.

[0053] It should be noted that, in some embodiments, when a receiving groove is provided on the machine 100 and a sinking groove 103 is provided at the bottom of the receiving groove, the above-mentioned matching hole is provided on the bottom wall of the sinking groove 103 .

[0054] In some other optional embodiments, only the sinking groove 103 may be provided on the machine platform 100 , that is, the mounting surface 101 is only provided with the sinking groove 103 , and in this case, the cutting piece 530 extends out of the sinking groove 103 .

[0055] In detail, the clamping device 400 includes two groups of clamping components 410 arranged on both sides of the resin block 2, and the clamping components 410 include a clamping drive component 411 and a clamping component 412 connected to each other. The clamping components 412 of the two groups of clamping components 410 can approach or move away from each other to clamp or release the resin block 2. The minimum height dimension of the clamping component 412 is greater than the maximum height dimension of the cutting component 530 of the cutting device 500. That is, the minimum height dimension of the clamping component 412 is greater than the maximum height dimension of the cutting component 530 to avoid interference between the cutting component 530 and the clamping component 412 when cutting the resin block 2.

[0056] The clamping assembly 410 further includes a guide member 413, which is fixedly mounted on the mounting surface 101. The guide member 413 is provided with a guide hole for the clamping member 412 to pass through. The clamping member 412 can move relative to the guide hole. The axis of the guide hole is parallel to the arrangement direction of the two groups of clamping assemblies 410 and is at an angle to the preset direction. It can be understood that when the clamping members 412 of the two groups of clamping assemblies 410 approach or move away from each other, the clamping members 412 can move relative to the axial direction of the guide hole. In this embodiment, the axis of the guide hole is perpendicular to the preset direction.

[0057] The clamping member 412 includes a mounting plate 4121 and a plurality of clamping portions 4122 arranged at intervals on the mounting plate 4121 along a preset direction. Each guide member 413 is provided with a plurality of guide holes arranged one-to-one corresponding to the plurality of clamping portions 4122. The mounting plate 4121 is connected to the driving end of the clamping driving member 411. It can be understood that since each clamping member 412 includes a plurality of clamping portions 4122 arranged at intervals along a preset direction, when the two groups of clamping assemblies 410 are close to each other to clamp the resin block 2, since each clamping assembly 410 has a plurality of clamping portions 4122, the stability of the two groups of clamping assemblies 410 when clamping the resin block 2 can be improved.

[0058] In summary, a resin cutting device 1 for orienting a crystal rod provided in an embodiment of the present invention comprises a machine table 100, a lifting device 300, an orienting instrument 200, a clamping device 400 and a cutting device 500. The machine table 100 has a mounting surface 101, and the mounting surface 101 is used to place a resin block 2 bonded with a silicon carbide crystal rod 3. The orienting instrument 200 is located above the mounting surface 101 and is used to detect the crystal rod. The lifting device 300 is installed on the machine table 100 and its driving end can be extended and retracted in the height direction. The lifting device 300 is used to lift one end of the resin block 2 to change the angle between the axis of the silicon carbide crystal rod 3 and the mounting surface 101. The cutting device 500 is used to cut from the first end to the second end of the resin block 2 along a preset direction. When the orientator 200 is detecting the crystal axis of the silicon carbide crystal rod 3, the lifting device 300 stops lifting and the clamping device 400 fixes the resin block 2. At this time, the cutting device 500 can cut from the first end to the second end of the resin block 2 along the preset direction. After the cutting is completed, after the resin block 2 is placed on a plane, the posture of the silicon carbide crystal rod 3 is still in an inclined state. At this time, the inclination direction of the silicon carbide crystal rod 3 is parallel to the crystal axis direction, so that the slicing device can slice the silicon carbide crystal rod 3. Through the cooperation of the lifting device 300, the clamping device 400, the orientator 200 and the cutting device 500, the processing efficiency of polishing the resin after the crystal rod orientation detection can be improved.
