[0032] The embodiment of the present invention provides a crystal ingot bonding and positioning jig 100 and a crystal ingot fixing device, which can realize auxiliary bonding of 8-inch crystal ingots and can also realize auxiliary bonding of 6-inch and 8-inch crystal ingots, and has wider applicability.

[0033] See also Figure 1 and Figure 2 , the embodiment of the utility model provides a crystal ingot bonding and positioning fixture 100, including a base 110, an end face bonding seat 130, a vertical bonding plate 150 and an elastic mechanism 170, the end face bonding seat 130 is arranged on the base 110, and the side wall of the end face bonding seat 130 is provided with a receiving groove 131 and a positioning protrusion 133 spaced apart in the vertical direction, the positioning protrusion 133 is located on the side of the receiving groove 131 away from the base 110, and is used to engage with the edge notch of the 8-inch crystal ingot correspondingly, the elastic mechanism 170 is arranged in the end face bonding seat 130, and is connected to the vertical bonding plate 150, the vertical bonding plate 150 has a first working position accommodated in the receiving groove 131 and a second working position out of the receiving groove 131, the elastic mechanism 170 is used to selectively pop the vertical bonding plate 150 from the first working position to the second working position in the horizontal direction, and the vertical bonding plate 150 is used to be bonded and fixed to the end face of the 6-inch crystal ingot in the second working position.

[0034] It should be noted that in this embodiment, both the 6-inch crystal rod and the 8-inch crystal rod can be silicon carbide crystal rods. When actually bonding the crystal rods, if the crystal rod is an 8-inch crystal rod, the vertical bonding plate 150 is set in the first working position. At this time, the vertical bonding plate 150 is accommodated in the accommodating groove 131, and the end face of the crystal rod can be directly bonded to the side wall of the end face bonding seat 130, and the positioning protrusion 133 is correspondingly engaged with the edge notch of the crystal rod to prevent the crystal rod from rotating until the glue layer is cured; if the crystal rod is a 6-inch crystal rod, the vertical bonding plate 150 is ejected to the second working position under the elastic force of the elastic mechanism 170, so that the vertical bonding plate 150 protrudes from the end face bonding seat 130, and the end face bonding of the 6-inch crystal rod is completed using the vertical bonding plate 150. It should be noted that the edge of the 8-inch crystal rod is provided with an edge notch (notch groove), while the edge of the 6-inch crystal rod remains intact. The specific structure of the 8-inch crystal rod and the 6-inch crystal rod can refer to the existing crystal rod structure. In addition, the bonding fixation can be achieved by a resin block here, and its bonding fixation material and bonding fixation means are also consistent with the crystal rod bonding means in the prior art. The crystal rod bonding positioning fixture 100 provided in this embodiment can achieve auxiliary bonding of the 8-inch crystal rod, effectively preventing the 8-inch crystal rod from rotating during the bonding process, and can also achieve end face bonding fixation of the 6-inch crystal rod, and can be compatible with the auxiliary bonding of 6-inch and 8-inch crystal rods, and has a wider applicability.

[0035] In this embodiment, a mounting groove 135 is further provided within the receiving groove 131, and an elastic mechanism 170 is mounted within the mounting groove 135. The thickness of the vertical adhesive plate 150 is adapted to the depth of the receiving groove 131, so that the vertical adhesive plate 150 is flush with the sidewalls of the end face adhesive seat 130 when in the first working position. Specifically, the mounting groove 135 is provided at the center of the inner sidewall of the receiving groove 131, and the elastic mechanism 170 can be compressed within the mounting groove 135, thereby ensuring that the vertical adhesive plate 150 is fully accommodated within the receiving groove 131. When the vertical adhesive plate 150 is in the first working position, the vertical adhesive plate 150 is flush with the sidewalls of the end face adhesive seat 130 surrounding the receiving groove 131, ensuring that the end faces of the 8-inch crystal ingot are aligned, thereby facilitating bonding and fixing.

[0036] In this embodiment, the shape of the receiving groove 131 is adapted to the shape of the vertical adhesive plate 150. Specifically, both the receiving groove 131 and the vertical adhesive plate 150 can be circular. When the vertical adhesive plate 150 is in the first working position, the vertical adhesive plate 150 can fit neatly into the receiving groove 131 and completely fill the receiving groove 131. This further makes the bonding surface of the 8-inch crystal ingot a complete planar structure, which is conducive to auxiliary bonding of the 8-inch crystal ingot. When the vertical adhesive plate 150 is in the second working position, the circular vertical adhesive plate 150 can be directly bonded to the end face of the 6-inch crystal ingot, achieving a better bonding effect.

[0037] Furthermore, the raised height of positioning protrusion 133 relative to end face bonding seat 130 is less than or equal to the distance between vertical bonding plate 150 and end face bonding seat 130 when in the second working position. Specifically, when vertical bonding plate 150 is in the second working position, the raised height of positioning protrusion 133 is less than the raised height of vertical bonding plate 150. This prevents positioning protrusion 133 from interfering with the 6-inch crystal ingot, ensuring that the end face of the 6-inch crystal ingot can be smoothly bonded to the end face of the 6-inch crystal ingot.

[0038] In this embodiment, the end face bonding seat 130 is located in the middle of the base 110, and the cross-sectional shape of the end face bonding seat 130 and the base 110 is an inverted T-shaped structure. Specifically, the end face bonding seat 130 is integrally provided with the base 110, and forms an inverted T-shaped fixture structure, which has better structural stability. Of course, in other preferred embodiments of the present invention, there can also be multiple end face bonding seats 130, and multiple end face bonding seats 130 are arranged on the base 110 at intervals. Each end face bonding seat 130 is provided with a positioning protrusion 133, an elastic mechanism 170 and a vertical bonding plate 150, which can simultaneously bond and fix multiple crystal rods.

[0039] See also Figures 3 to 5 The elastic mechanism 170 includes an elastic member 171 and an elastic switch 173. The elastic member 171 is compressed and arranged in the mounting groove 135 and is connected to the vertical adhesive plate 150. The elastic switch 173 is movably arranged in the mounting groove 135 and partially extends out of the end surface adhesive seat 130 to limit the elastic member 171. Specifically, the receiving groove 131 can be opened on the front side of the end surface adhesive seat 130, and the elastic switch 173 can be partially extended to the back side of the end surface adhesive seat 130, so that the elastic switch 173 can be manually controlled from the back side, thereby limiting or releasing the limit of the elastic member 171, so that the vertical adhesive plate 150 can be switched between the first working position and the second working position.

[0040] Furthermore, the elastic switch 173 includes a guide post 175 and a retaining member 177. One end of the guide post 175 is connected to the vertical adhesive plate 150, and the other end extends out of the end surface adhesive seat 130 in a direction away from the vertical adhesive plate 150. The retaining member 177 is rotatably disposed at the end of the guide post 175 extending out of the end surface adhesive seat 130 and is configured to selectively abut against a side surface of the end surface adhesive seat 130 away from the vertical adhesive plate 150 to define the position of the guide post 175. Specifically, the guide post 175 can be made of a hard material, such as stainless steel. On the one hand, it can abut against the vertical adhesive plate 150 to secure the vertical adhesive plate 150, and on the other hand, it can cooperate with the retaining member 177 to retract the vertical adhesive plate 150. In actual use, when the vertical adhesive plate 150 needs to pop out to the second working position, the limit on the elastic member 171 can be released by the clamping member 177 and the guide column 175, so that the vertical adhesive plate 150 pops out under the elastic force of the elastic member 171. When the vertical adhesive plate 150 needs to be restored to the first working position, the vertical adhesive plate 150 can be pressed to the first working position, and the vertical adhesive plate 150 can be fixed by the clamping member 177 and the guide column 175, and the limit on the elastic member 171 can be achieved.

[0041] In this embodiment, a guide hole 137 is provided on the side of the end face adhesive seat 130 away from the vertical adhesive plate 150, and the guide hole 137 is connected to the mounting groove 135. The guide column 175 is movably inserted into the guide hole 137, and a guide groove 139 is also provided on the side of the end face adhesive seat 130 away from the vertical adhesive plate 150. The guide groove 139 is connected to the guide hole 137 and is separated from the mounting groove 135, and the guide groove 139 is used to accommodate the clamping member 177. Specifically, the guide groove 139 can be vertically placed on the upper side of the guide hole 137, and the clamping member 177 is sheet-shaped and can be accommodated in the guide groove 139. In actual use, when the vertical adhesive plate 150 needs to be popped out to the second working position, the clamping member 177 can be manually moved so that the clamping member 177 is rotated to correspond to the guide groove 139 and then released. At this time, the elastic member 171 applies elastic force to the vertical adhesive plate 150 and drives the guide column 175 and the clamping member 177 to move horizontally. Since the clamping member 177 is aligned with the guide groove 139, the vertical adhesive plate 150 can be opened and closed. Correspondingly, the clamping member 177 can be partially installed in the guide groove 139. After being in place, the clamping member 177 can be abutted against the inner wall of the guide groove 139 to keep the vertical adhesive plate 150 fixed in the second working position. When the vertical adhesive plate 150 needs to be retracted, the vertical adhesive plate 150 can be pressed by hand or the clamping member 177 can be pulled by hand to drive the vertical adhesive plate 150 to retract to the first working position. At this time, the clamping member 177 can be completely disengaged from the guide groove 139, and after rotating, it can be abutted against the back of the end face adhesive seat 130 to achieve clamping positioning.

[0042] In this embodiment, the elastic member 171 includes a spring, which is compressed and arranged between the vertical adhesive plate 150 and the end surface adhesive seat 130 and is sleeved outside the guide column 175, so that the vertical adhesive plate 150 moves more smoothly and reliably during the pop-up and retraction process.

[0043] It should be noted that when the vertical adhesive plate 150 pops up to the second working position, the clamping member 177 can be held and limited by hand or other supporting members to prevent the vertical adhesive plate 150 from rebounding under the supporting action of the 6-inch crystal rod.

[0044] The embodiment of the present invention also provides a crystal ingot fixing device, including a machine base and the aforementioned crystal ingot bonding and positioning fixture 100, the crystal ingot bonding and positioning fixture 100, including a base 110, an end surface bonding seat 130, a vertical bonding plate 150 and an elastic mechanism 170, the end surface bonding seat 130 is arranged on the base 110, and the side wall of the end surface bonding seat 130 is provided with a receiving groove 131 and a positioning protrusion 133 spaced apart in the vertical direction, the positioning protrusion 133 is located on the side of the receiving groove 131 away from the base 110 , used to engage with the edge notch of the 8-inch crystal ingot. The elastic mechanism 170 is disposed within the end face bonding seat 130 and connected to the vertical bonding plate 150. The vertical bonding plate 150 has a first working position in which it is accommodated in the receiving groove 131 and a second working position in which it is released from the receiving groove 131. The elastic mechanism 170 is used to selectively eject the vertical bonding plate 150 horizontally from the first working position to the second working position. In the second working position, the vertical bonding plate 150 is bonded and fixed to the end face of the 6-inch crystal ingot. The base 110 is fixedly mounted on the machine base.

[0045] Furthermore, the machine base can fix the base 110, and a cutting device can be set on the machine base to realize the cutting action of the crystal rod. The basic structure and cutting principle of the cutting device are not introduced in detail here. For details, please refer to the existing crystal rod cutting device.

[0046] To sum up, the crystal rod bonding and positioning jig 100 and the crystal rod fixing device provided by the embodiment of the present invention have a receiving groove 131 and a positioning protrusion 133 spaced apart in the vertical direction on the side wall of the end face bonding seat 130, and the positioning protrusion 133 is located on the side of the receiving groove 131 away from the base 110. The elastic mechanism 170 is arranged in the end face bonding seat 130 and is connected to the vertical bonding plate 150. The vertical bonding plate 150 can be popped out from the first working position to the second working position under the elastic force of the elastic mechanism 170. During actual bonding of a crystal ingot, if the ingot is an 8-inch ingot, the vertical bonding plate 150 is positioned in the first working position. At this point, the vertical bonding plate 150 is accommodated in the receiving groove 131, and the end face of the ingot can be directly bonded to the sidewall of the end face bonding seat 130. The positioning protrusions 133 are correspondingly engaged with the edge notches of the ingot to prevent the ingot from rotating until the adhesive layer solidifies. If the ingot is a 6-inch ingot, the vertical bonding plate 150 is ejected to the second working position under the elastic force of the elastic mechanism 170, thereby protruding from the end face bonding seat 130. The end face bonding of the 6-inch ingot is completed using the vertical bonding plate 150. Compared to the prior art, the present invention can achieve auxiliary bonding of 8-inch ingots, effectively preventing the 8-inch ingot from rotating during the bonding process. It can also achieve end face bonding and fixation of 6-inch ingots, and is compatible with auxiliary bonding of both 6-inch and 8-inch ingots, thus providing wider applicability. Using this fixture, after the 6-inch and 8-inch silicon carbide crystal rods are assisted in gluing the resin blocks, the horizontal crystal phase deviation angle of the silicon carbide can be controlled within 10 minutes.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
