Description
Technical Field
[0001] The utility model relates to the technical field of single crystal silicon manufacturing and processing, in particular to a round rod gluing tool. Background Art
[0002] The single-crystal round bar gluing in the machining workshop has formed a development scale in the industry, and the splicing and gluing of non-standard bars is currently a commonly used method. That is, the original single-crystal round bar is first cut by a cutting machine to form multiple sections of non-fixed-length silicon bars, and the cut non-fixed-length silicon bars are squared by a squarer, and then the squared silicon bars are ground and chamfered, etc., so that the silicon bars meet the requirements in terms of size and flatness, and are spliced into fixed-length bars, and then packaged.
[0003] After the crystal rod is cut, a large number of non-fixed length crystal rods are generated. Generally, all finished square rods need to be spliced and paired before they can be shipped to the customer. However, when the crystal rods are manually bonded, the crystal rods cannot be stably stabilized. Therefore, the bonding process is prone to abnormalities such as bumps, empty glue, bubbles, and crystal line deviation, which is inefficient and affects the processing yield. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:
[0026] Embodiment 1:
[0027] like Figures 1 to 3As shown, this embodiment provides a single-wafer rod 6 bonding auxiliary device, including a base 1, a truncated table 11 for placing the single-wafer rod 6 to be bonded is provided at the center of the base 1, and a plurality of fixing components 2 are provided along the circumference of the truncated table 11, and an auxiliary fastening component 3 is movably mounted on each fixing component 2, and the plurality of auxiliary fastening components 3 are used to abut against the side wall of the single-wafer rod 6 to fix the single-wafer rod 6, and a crystal line measurement meter component 4 for adjusting the concentricity of the single-wafer rod 6 is also fixed on the base 1. In this embodiment, the fixing components 2 include three, each fixing component 2 corresponds to an auxiliary fastening component 3, and the three fixing components 2 are evenly distributed and fixed along the circumference of the truncated table 11.
[0028] Among them, the fixing component 2 includes a fixing plate 21 and a connecting rod 22. The short side of the fixing plate 21 is fixed on the base 1, and the long side of the fixing plate 21 is axially arranged along the single crystal rod 6. A rotating disk 23 is fixedly installed at one end of the connecting rod 22. The rotating disk 23 can be threadedly connected to the connecting rod 22. The other end passes through the fixing plate 21 and is fixed with an auxiliary fastening component 3. The connecting rod 22 drives the auxiliary fastening component 3 to abut against the side wall of the single crystal rod 6 under the push of the rotating disk 23.
[0029] The auxiliary fastening assembly 3 includes a mounting plate 31 , one side of which is fixedly connected to the connecting rod 22 , and the other side of the mounting plate 31 is provided with a plurality of auxiliary chucks facing the single wafer rod 6 , and the plurality of auxiliary chucks are arranged circumferentially along the single wafer rod 6 .
[0030] In order to prevent the rigid structure from directly abutting against the side wall of the crystal rod and causing wear to the crystal rod, the auxiliary chuck includes a support plate 32 and a clamping column. One end of the support plate 32 is fixed on the mounting plate 31, and the other end is vertically fixed with the clamping column. A buffer pad 33 is sleeved on the clamping column. The material of the fixing component 2 is steel plate (cast steel). In order to prevent the rigid structure from directly contacting the side wall of the single crystal round rod 6 and causing wear, the buffer pad 33 is made of plastic material such as PE buffer pad 33 or rubber buffer pad 33.
[0031] In order to make the mounting plate 31 evenly stressed and more stable when the connecting rod 22 pushes the auxiliary fastening assembly 3, the fixing assembly 2 also includes two fixing rods 24, each fixing rod 24 is installed with a fastener 25 at one end, and the other end passes through the fixing plate 21 and is fixed on the mounting plate 31 of the auxiliary fastening assembly 3. The fastener 25 can be a locking nut. When adjusted to the right position, the locking nut is tightened to fix the fixing rod 24 and the mounting plate 31. The two fixing rods 24 are arranged on both sides of the connecting rod 22 along the length direction of the fixing plate 21, so that the fixing between the mounting plate 31 and the fixing plate 21 is more stable and evenly stressed. After the distance between the fixing rod 24 and the fixing plate 21 is adjusted to the right position, the fixing rod can be fixed by tightening the locking nut.
[0032] In order to increase the stability of the fixing assembly 2 so that the fixing plate 21 can be more stably installed on the base 1, baffles 26 are fixed on both sides of the long side of the fixing plate 21. Figure 1 As shown, the baffle 26 may be a wedge-shaped block, which is used to more stably fix the fixing plate 21 on the base 1 to increase stability.
[0033] In order to reduce the number of adjustments, a limit assembly 5 can be provided. The limit assembly 5 includes a side plate 51. The side plate 51 is provided with a strip hole 52 along the axial direction of the connecting rod 22. One end of the side plate 51 is fixed to the fixing plate 21 by a screw, and the other end is fixed with a limit screw 53. The limit screw 53 is arranged perpendicular to the axial direction of the connecting rod 22 and extends to the position between the mounting plate 31 and the round rod. The limit screw 53 is used to mark the farthest distance between the mounting plate 31 and the fixing plate 21 to help users quickly locate. In this way, in the face of round rods of different sizes, it is only necessary to adjust the distance between the fixing plate and the mounting plate to a suitable position, and then tighten the bolts or other fixing structures (nuts and bolts fit) in the strip hole to fix the first side plate to the side of the mounting plate.
[0034] In this way, the auxiliary device is used for single-wafer round rods 6 of different sizes. When it is used continuously for round rods of the same size, the distance between the two fixed components 2 and the auxiliary fastening components 3 located on both sides of the crystal line measurement meter component 4 is fixed, and only the first adjustment is required. Thereafter, only the distance between the fixed component 2 away from the crystal line measurement meter component 4 and the auxiliary component needs to be adjusted.
[0035] Among them, the crystal line measurement and dialing assembly 4 includes a supporting column 41, a connecting plate 42 and a movable plate 43. One end of the supporting column 41 is fixed on the base 1, and the other end is fixedly sleeved on the connecting plate 42. One end of the movable plate 43 is movably connected to the connecting plate 42 (it can be pin-connected), and the other end is provided with a micrometer 44, which is arranged close to the single crystal rod 6.
[0036] The usage process of this embodiment:
[0037] For the round rod to be bonded, check whether the size of the round rod is consistent with that of the round rod used last time. If not, first record the size of the round rod, and then adjust the distance between the three auxiliary fastening components 3 and the fixed component 2 so that the auxiliary fastening component 3 moves outward to make room for the installation of the round rod. Specifically, loosen the locking nut of the fastener 25, and then pull the rotating disk 23, which drives the connecting rod 22 and the mounting plate 31 to move outward to reserve installation space for the installation position of the round rod. Then use a clamp to place the round rod on the round table 11, and then push the three rotating disks 23 again to move the mounting plate 31 toward the direction of the round rod until the first auxiliary chuck abuts against the round rod. When adjusting the distance between the mounting plate 31 and the round rod, observe the value on the micrometer 44 at the same time, fine-tune the position of the movable plate 43, and adjust the concentricity. When the adjustment is completed, tighten the locking nut to stably fix the round rod, and then wait for the round rod to be bonded.
[0038] After the round rod is fixed by gluing, there is no need to remove the auxiliary fastening components 3 on both sides of the crystal line measurement meter component 4. You only need to remove the position of the third auxiliary fastening component 3 far away from the crystal line measurement meter component 4. In this way, next time you glue the round rod of the same size again, you do not need to adjust the positions of the three auxiliary fastening components 3 again. You only need to loosen the locking nut of the third auxiliary fastening component 3 farthest from the crystal line measurement meter component 4, pull the rotating disk 23, so that the auxiliary chuck loosens the round rod, leaving a gap for the round rod to be taken out, and take the round rod out of the gap. When using it again, if it is a round rod of the same size, you only need to adjust the position of the third auxiliary fastening component 3, and fix the rest as in the above steps.
[0039] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
