Description

Technical Field

[0001] The utility model is mainly used in the field of SiC crystal rod bonding processing, and specifically relates to a fixture for improving the crystal orientation of a SiC crystal rod. Background Art

[0002] When multiple SiC crystal rods are manually bonded, the position of the reference plate needs to be adjusted for each bond. Since there is a certain error when the screws of the reference plate are tightened, the crystal orientation results of the final product will have a large deviation. Using equipment for automatic bonding can improve this problem, but the equipment is expensive to purchase and the investment cost is huge, which is not economically cost-effective. Utility Model Content

[0003] In view of the existing quality problems, the utility model provides a fixture for improving the crystal orientation of SiC crystal rods, which solves the above-mentioned background problems.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a jig for improving the crystal orientation of SiC crystal rods. The jig is a device composed of a reference plate, a left dovetail seat fixed block, a right dovetail seat fixed block, a left dovetail seat fixed block screw, a right dovetail seat fixed block screw, a dovetail seat movable block screw, a bonding platform and a reference plate screw. The left dovetail seat fixed block screw and the right dovetail seat fixed block screw fix the left dovetail seat fixed block and the right dovetail seat fixed block on the bonding platform, the reference plate screws erect the reference plate on the bonding platform, and the dovetail seat movable block screw is on the bonding platform. The sealing ring is embedded in the groove of the reference plate, the dovetail seat block is installed on the bonding platform to fix the standard position of the dovetail seat, the reference plate is fixed on the crystal rod bonding platform, and the reference plate can be fine-tuned according to the actual crystal orientation result.

[0005] In an embodiment of the present invention, the reference plate is a reference surface of the end surface of the crystal rod when the crystal rod is bonded.

[0006] In one embodiment of the present invention, the reference plate has air holes, and the air holes are connected to the air pipe and the vacuum generator.

[0007] In an embodiment of the present invention, the sealing ring is used to fix the crystal rod when the crystal rod is bonded.

[0008] In one embodiment of the utility model, the reference plate has a groove, and the sealing ring is embedded in the groove of the reference plate.

[0009] In one embodiment of the utility model, the bonding platform is used to fix the dovetail seat when bonding the crystal rod.

[0010] In one embodiment of the present invention, the dovetail seat stopper is used to fix the dovetail seat with the bonding platform.

[0011] In one embodiment of the utility model, the bottom of the reference plate has screw holes, and the bonding platform has a corresponding installation position. After the reference plate is installed, the screws are tightened to fix the reference plate and the bonding platform, and the position of the reference plate can be fine-tuned.

[0012] In one embodiment of the utility model, the dovetail seat block is divided into a fixed block and a movable block. The fixed block is fixed to one side of the bonding platform with screws, and the movable block is placed on the bonding platform together with the dovetail seat. The movable block is locked with screws to fix the dovetail seat.

[0013] In summary, the advantages and features of the embodiments of the present utility model are that the fixture design can meet the requirements of bonding multiple crystal rods while improving the crystal orientation. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0026] Reference Figure 1, fix the left dovetail seat fixed block 2 and the right dovetail seat fixed block 3 on the bonding platform 8 using the left dovetail seat fixed block screw 7 and the right dovetail seat fixed block screw 4. According to the position where the first crystal rod needs to be bonded to the dovetail seat, place the dovetail seat used for bonding the crystal rod on the bonding platform 8 between the left dovetail seat fixed block 2 and the dovetail seat movable block 6, tighten the dovetail seat movable block screw 5, fix the dovetail seat, place the crystal rod at the desired bonding position, close to the sealing ring on the reference plate 1, open the air pipe, and fix the crystal rod in On the reference plate, after the glue of the first crystal rod is cured, loosen the screw 5 of the movable stopper of the dovetail seat, and adjust the position of the dovetail seat on the bonding platform 8 between the left dovetail seat fixed stopper 2 and the movable stopper 6 of the dovetail seat according to the bonding position of the second crystal rod, then tighten the screw 5 of the movable stopper of the dovetail seat, fix the dovetail seat, and continue to bond the second crystal rod. Similarly, complete the bonding of multiple crystal rods, and cut the crystal rods after bonding. After cutting, fine-tune the installation position of the reference plate 1 according to the actual deviation result of the crystal rod, so as to achieve the purpose of improving the crystal orientation.
