Description

Technical Field

[0001] The utility model relates to the technical field of single crystal silicon manufacturing and processing, in particular to an auxiliary positioning device for round rod gluing tooling. Background Art

[0002] The 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 rod specifications, and then packaged.

[0003] After the crystal rod is cut, a large number of non-fixed length crystal rods will be produced. Generally, all finished square rods need to be spliced ​​and paired before they can be shipped to the customer. When the crystal rod is squared, the number of squares needs to be increased, which seriously reduces the processing efficiency. Manual splicing cannot effectively prevent crystal rod damage and quality abnormalities. In addition, when the crystal rod is manually bonded, the personnel directly operate without protection, which is prone to abnormalities such as bumps, empty glue, bubbles, and crystal line deviation. This invisibly increases the difficulty of processing and produces corresponding product bumps, bevels and other product defects. 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.

[0029] The present invention is described in detail below with reference to the accompanying drawings and in combination with embodiments:

[0030] Embodiment 1:

[0031] like Figures 1 to 4As shown, this embodiment provides a fixing device for gluing a single-crystal round rod 9, comprising a base 1, a truncated table 11 for placing the round rod to be glued is provided at the center of the base 1, a plurality of first fixing components 2 and second fixing components 5 for abutting against the side wall of the round rod to fix the round rod are provided along the circumference of the truncated table 11, the first fixing components 2 and the second fixing components 5 are staggered on the base 1, a first positioning component 4 for limiting the distance between the first fixing component 2 and the round rod is provided on the first fixing component 2, and a crystal line measuring meter component 8 for adjusting the concentricity of the round rod is also fixed on the base 1.

[0032] In this embodiment, there are three first fixing components 2 and three second fixing components 5, each first fixing component 2 corresponds to an auxiliary fastening component, each second fixing component 5 corresponds to a second auxiliary fastening component 6, and the three first fixing components 2 and the three second fixing components 5 are evenly staggered and fixed on the base 1 along the circumference of the truncated table 11. The first fixing component 2 is pressed against the side of the round rod, and the second fixing component 5 is pressed against the bottom of the round rod.

[0033] Specifically, Figure 2-Figure 3 As shown, the first fixing assembly 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. The long side of the fixing plate 21 is arranged along the axial direction of the round rod. A rotating disk 23 is installed at one end of the connecting rod 22. The other end passes through the fixing plate 21 and is fixed with a first auxiliary fastening assembly 3. The connecting rod 22 drives the first auxiliary fastening assembly 3 to abut against the side wall of the round rod under the push of the rotating disk 23. In order to make the fixing plate 21 more stably fixed on the base 1 and increase stability, baffles 26 can be fixed on both sides of the long side of the fixing plate 21.

[0034] like Figure 3 As shown, the first auxiliary fastening assembly 3 includes a mounting plate 31, one side of the mounting plate 31 is fixedly connected to the connecting rod 22, and the other side of the mounting plate 31 is provided with a plurality of first auxiliary chucks facing the round rod, and the plurality of first auxiliary chucks are arranged along the circumference of the round rod.

[0035] 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 first auxiliary chuck includes a support plate 32 and a clamping column 33. 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 33. A buffer pad 34 is sleeved on the clamping column 33. The material of the first 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 9 and causing wear, the buffer pad 34 is made of plastic material such as PE buffer pad 34 or rubber buffer pad 34.

[0036] In order to make the force on the mounting plate 31 uniform and more stable when the connecting rod 22 pushes the first auxiliary fastening component 3, the first fixing component 2 also includes two fixing rods 24. Each fixing rod 24 is installed with a fastener at one end (the fastener can be a locking nut 25), and the other end passes through the fixing plate 21 and is fixed on the mounting plate 31 of the first auxiliary fastening component 3. When adjusted into place, the locking nut 25 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 fixation between the mounting plate 31 and the fixing plate 21 is more stable and the force is uniform. At the same time, in order to increase the stability of the first fixing component 2 and enable the fixing plate 21 to be more stably installed on the base 1, baffles 26 are fixed on both sides of the long side of the fixing plate 21, such as 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.

[0037] In order to reduce the number of adjustments and help workers quickly locate the adjustment position, a first positioning component 4 is set to limit the distance between the mounting plate 31 and the fixed plate 21, and the farthest distance that can be adjusted between the mounting plate 31 and the fixed plate 21 is calibrated to limit the adjustment position. The first positioning component 4 includes a first side plate 41, and the first side plate 41 is provided with a mounting hole 42 (two parallel strip holes 72) along the axial direction of the connecting rod 22. One end of the first side plate 41 is fixed to the fixed plate 21 by screws, and the other end is fixed with a limiting screw 43. The limiting screw 43 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. In this way, in the face of round rods of different sizes, it is only necessary to adjust the distance between the fixed plate 21 and the mounting plate 31 to a suitable position, and then tighten the bolts or other fixing structures in the mounting hole 42 to fix the first side plate 41 to the side of the mounting plate 31.

[0038] In this embodiment, two sets of fixing components are used to limit the side and bottom of the round rod respectively. Specifically, the second fixing component 5 includes a fixing block 51 and a push rod 52. The fixing block 51 is fixed on the base 1. A push plate 53 is fixed at one end of the push rod 52, and a second auxiliary fastening component 6 is fixed at the other end that passes through the fixing block 51. The push rod 52 drives the second auxiliary fastening component 6 to abut against the bottom of the round rod under the push of the push plate 53.

[0039] Specifically, the second auxiliary fastening assembly 6 includes a clamping plate 61, a second clamping head 62 is fixed on the clamping plate 61, a protective pad 63 is sleeved on the second clamping head 62, and the push rod 52 is fixedly connected to the clamping plate 61. Similarly, in order to make the force more uniform when the push rod 52 pushes the clamping plate 61, and the clamping plate 61 and the fixed block 51 are more stable, a plurality of support rods 54 are fixed between the opposite surfaces of the clamping plate 61 and the fixed block 51. The support rod 54 is a telescopic rod that can be extended and retracted with the movement of the push rod 52. One end of the support rod 54 is fixed on the fixed block 51, and the other end is fixed on the clamping plate 61. A fixing bolt 55 for fastening the push rod 52 is provided on the fixed block 51. When adjusted in place, the fixing bolt 55 is tightened to relatively fix the push rod 52 and the fixed block 51.

[0040] Similarly, in order to cooperate with the position limitation of the first fixing component 2, a second positioning component 7 is also required to limit the position of the second fixing component 5. The second positioning component 7 includes a second side plate 71, which is arranged parallel to the push rod 52 and fixed on the base 1. The second side plate 71 is provided with a strip hole 72 along the length direction of the push rod 52. A limiting rod 73 is movably connected in the strip hole 72. The limiting rod 73 is arranged perpendicular to the push rod 52 and extends to the position between the clamping plate 61 and the round rod. The second positioning component 7 limits the distance between the clamping plate 61 and the fixing block 51, marks the farthest distance that can be adjusted between the clamping plate 61 and the fixing block 51 (matching the first positioning component 4), and limits the adjustment position. In this way, when facing round rods of different sizes, it is only necessary to cooperate with the first positioning component 4, adjust the distance between the clamping plate 61 and the fixing block 51 to a suitable position, and then tighten the limiting rod 73 in the strip hole 72. The limiting rod 73 can be fixed by fixing nuts and chucks, and can also be fixed in the strip hole 72 by combining nuts and bolts.

[0041] In this way, the present device is used for single-wafer round bars 9 of different sizes. When it is used continuously for round bars of the same size, the distance between the two first fixing components 2 and the first auxiliary fastening component 3 located on both sides of the crystal line measurement meter component 8 is fixed, and the distance between the second fixing component 5 and the second auxiliary fastening component 6 is also fixed. Therefore, only the first adjustment is required, and thereafter only the distance between those fixing components and auxiliary components away from the crystal line measurement meter component 8 needs to be adjusted.

[0042] Among them, in order to ensure that the concentricity of the single crystal round rod 9 after gluing meets the processing requirements, the crystal line measurement and dial assembly 8 includes a supporting column 81, a connecting plate 82 and a movable plate 83. One end of the supporting column 81 is fixed on the base 1, and the other end is fixedly sleeved on the connecting plate 82. One end of the movable plate 83 is movably connected to the connecting plate 82 (for example, it can be pinned), and the other end is provided with a micrometer 84, which is set close to the round rod.

[0043] The usage process of this embodiment:

[0044] 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 second fixing assembly 5 and the three first auxiliary fastening assemblies 3 and the first fixing assembly 2. Specifically, first loosen the fixing bolts 55 of all the fixing assemblies and the locking nuts 25 of the fasteners, and then pull the rotating disk 23, the rotating disk 23 drives the connecting rod 22 and the mounting plate 31 to move outward, and the push plate 53 pulls the clamp 61 and the push rod 52 to move outward, and reserves 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 rotating disk 23 and the push plate 53 again, so that the mounting plate 31 and the clamp 61 move toward the direction of the round rod until the first auxiliary clamp and the second clamp 62 are both in contact with the round rod. When pushing the mounting plate 31, check whether it reaches the position of the limit screw 43, and at the same time check whether the clamp 61 reaches the position of the limit rod 73. If so, it means that the adjustment is completed.

[0045] While adjusting the distances between the mounting plate 31, the clamping plate 61 and the round rod, observe the value on the micrometer 84, adjust the concentricity, and tighten the locking nut 25 and the fixing bolt 55 after the adjustment is completed to stabilize and fix the round rod, and then wait for the round rod to be bonded. After the round rod is glued and fixed, there is no need to remove the auxiliary fastening components on both sides of the crystal line measurement meter assembly 8. It is only necessary to remove the position of the third auxiliary fastening component away from the crystal line measurement meter assembly 8. In this way, the next time the round rod of the same size is bonded again, there is no need to adjust the positions of the three auxiliary fastening components again. Loosen the locking nut 25 of the third auxiliary fastening component, pull the rotating disk 23 and the push disk 53, so that the second chuck 62 and the first auxiliary chuck loosen 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, it is only necessary to adjust the position of the third auxiliary fastening component, and the rest can be fixed as in the above steps.

[0046] 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.
