[0021] Preferably, a through groove for the seesaw to rotate downward is provided on the side wall of the semicircular rod discharge groove.

[0022] A method for using a silicon crystal rod grinding and processing device comprises the following steps:

[0023] S1. Use an external motor to drive the rotating column to rotate, and place the silicon crystal rod to be ground on the upper side of the shell. When the semi-circular rod discharge slot and the semi-circular rod placement slot are aligned, the two form a complete cylindrical slot body, and the silicon crystal rod falls into it;

[0024] S2. The rotating column drives the slide and the silicon crystal rod to perform circular motion. During this process, the silicon crystal rod moves from being placed in the semicircular rod groove to contacting the inner wall of the shell and is pushed back by it, thereby squeezing the slide compression spring to retract into the slide groove, that is, the silicon crystal rod is pressed against the inner wall of the shell by the slide;

[0025] S3, the silicon crystal rod is driven by the shell to rotate with the circular motion, so that the silicon crystal rod rubs in the grinding semi-circular rod groove to achieve grinding. When the grinding semi-circular rod groove reaches the discharge semi-circular rod groove, the silicon crystal rod is pushed into the discharge semi-circular rod groove and falls down to be discharged;

[0026] S4, the silicon crystal rod contacts the coarse grinding block in the grinding semicircular rod groove, and performs coarse grinding while rotating. As the outer diameter of the silicon crystal rod is reduced after grinding, the slide moves toward the inner wall of the shell to fill the position. During this process, the rack pulls the toothed disc to rotate along the gear, and the toothed disc drives the tooth column and the roller to rotate using the half gear ring, so that the coarse grinding block on the surface of the roller is switched to the fine grinding block, and after further grinding, the roller continues to rotate to switch to the fine grinding block;

[0027] S5. When the slide is squeezed in by the silicon crystal rod, the rack is pushed into the insertion hole by the slide, so that the shaft squeezes the top spring and is locked by the latch. When the slide slides outward, the locked shaft and rack can pull the gear to switch the grinding block. When the grinding semicircular rod groove is aligned and the semicircular rod groove is discharged to release the silicon crystal rod, the silicon crystal rod presses down the seesaw to push the moving pin upward. The top of the moving pin pushes the shaft to rotate along the notch. At this time, the dislocation of the latch releases the lock, and the top spring pushes the shaft to slide outward and rotate for double reset.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In the present invention, the silicon crystal rod is moved from being placed in the semi-circular rod groove to contacting the inner wall of the shell, and is pushed back by the inner wall to squeeze the compression spring of the slide seat and retract into the slide groove, that is, the silicon crystal rod is pressed against the inner wall of the shell by the slide seat. Compared with the existing manual operation of fixing the silicon crystal rod with clamps at both ends, the slide seat can utilize the rotation of the rotating column to automatically load the silicon crystal rod during alignment and then automatically fix it. The grinding semi-circular rod groove and the inner wall of the shell fix the silicon crystal rod in full contact, which can comprehensively disperse the force acting on the silicon crystal rod, and effectively reduce the possibility of the grinding force causing damage to the silicon crystal rod itself along the fixed point.

[0030] In the present invention, the silicon crystal rod is driven by the shell to rotate along with the circular motion, so that the silicon crystal rod is rubbed in the grinding semicircular rod groove to achieve grinding. When the grinding semicircular rod groove reaches the discharge semicircular rod groove, the silicon crystal rod is pushed into the discharge semicircular rod groove and falls down to be discharged. Compared with the existing manual operation of grinding parts contacting the silicon crystal rod for grinding, the above-mentioned grinding semicircular rod groove can achieve grinding through the friction force generated by the fixed rotation of the rotating column, and automatically discharges after grinding. There is no need for the user to operate one by one in each step, which is more convenient to use and optimizes the shutdown and disassembly steps to achieve assembly line operation.

[0031] In the present invention, the outer diameter of the silicon crystal rod is reduced after grinding, so that the slide moves toward the inner wall of the shell to fill the position. In this process, the rack pulls the toothed disc to rotate along the gear, and the toothed disc drives the toothed column and the roller to rotate by using the half-toothed ring, so that the coarse grinding block on the surface of the roller is switched to the fine grinding block, and after further grinding, the roller continues to rotate to switch the fine grinding block. Compared with the existing three types of grinding blocks acting on the silicon crystal rod synchronously, the above-mentioned roller can use the gap between the slide and the shell to realize the switching of each grinding block, so that the silicon crystal rod is subjected to different grinding one by one, which can effectively avoid the different vibration frequencies of different grindings from impacting the silicon crystal rod and causing damage, and can also avoid the torsional shear force between different grinding positions from damaging the silicon crystal rod, and the switching of the grinding blocks is automatically controlled by the outer diameter of the silicon crystal rod, which has better convenience in use.

[0032] When the sliding seat is squeezed into the silicon crystal rod, the rack is pushed into the insertion hole by the sliding seat, so that the rotating shaft squeezes the top spring and is locked by the latch teeth. When the sliding seat slides outward, the locked rotating shaft and the rack can pull the gear to switch the grinding block. When the grinding semicircular rod groove is aligned and the semicircular rod groove is discharged to release the silicon crystal rod, the silicon crystal rod presses the seesaw downward to push the moving pin to move upward, and the top of the moving pin pushes the rotating shaft to rotate along the notch. At this time, the latch teeth are misaligned to release the lock, and the top spring pushes the rotating shaft to slide outward and rotate for dual reset. In this way, during the discharge of the silicon crystal rod, the grinding block on the roller is automatically reset from the fine grinding block to the coarse grinding block, and when the sliding seat is squeezed by the silicon crystal rod in the initial stage, the roller will not rotate, nor will the fine grinding block contact the silicon crystal rod first, which can effectively avoid abnormal grinding of the silicon crystal rod during the switching process of the grinding block, and ensure that the overall grinding process is more stable and reliable.

As the outer diameter of the silicon crystal rod is reduced after grinding, the slide 42 moves toward the inner wall of the shell 1 to fill the position. During this process, the rack 475 pulls the toothed disc 472 to rotate along the gear 473, and the toothed disc 472 uses the half-toothed ring 4713 to drive the toothed column 4711 and the roller 477 to rotate, so that the coarse grinding block 478 on the surface of the roller 477 is switched to the fine grinding block 479, and after further grinding, the roller 477 continues to rotate to switch to the fine grinding block 4710.

[0055] A reset assembly 4714 is disposed on the rack 475 , the slide seat 42 and the rotating column 2 .

[0056] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, the reset assembly 4714 includes a rotating shaft 47141 rotatably connected to the end of the rack 475, a socket 47142 corresponding to the rotating shaft 47141 is provided on the side wall of the slide groove 41, and the rotating shaft 47141 is inserted into the socket 47142, and a top spring 47143 matching the rotating shaft 47141 is provided in the socket 47142.

[0057] The lower side of the surface of the rotating shaft 47141 and the bottom of the inner wall of the insertion hole 47142 are fixedly provided with mutually matching latch teeth 47144. When the slide 42 is squeezed into the silicon crystal rod, the rack 475 is pushed into the insertion hole 47142 by the slide 42, so that the rotating shaft 47141 squeezes the top spring 47143 and is locked by the latch teeth 47144.

[0058] The bottom of the slide 42 is rotatably provided with a seesaw 47145, and one end of the seesaw 47145 extends to the bottom of the grinding semi-circular rod groove 44, the interior of the slide 42 is provided with a vertical hole 47146, and the two ends of the vertical hole 47146 are respectively connected to the bottom of the slide 42 and the column hole 474, and the interior of the vertical hole 47146 is slidably connected with a moving pin 47147, and the bottom end of the moving pin 47147 abuts against the other end of the seesaw 47145, and the surface of the rotating shaft 47141 is provided with a vertical hole 47146. A notch 47148 is provided to match the top of the movable pin 47147. When the grinding semicircular rod groove 44 is aligned with the discharge semicircular rod groove 46 to release the silicon crystal rod, the silicon crystal rod presses down the seesaw 47145, so that it pushes the movable pin 47147 to move upward, and the top of the movable pin 47147 pushes the rotating shaft 47141 to rotate along the notch 47148.

[0059] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, a resistance rubber strip is arranged on the inner wall of the shell 1, which can increase the friction force when the inner wall of the shell 1 contacts the silicon crystal rod, so that the rod body can be driven to rotate stably.

When the seesaw 47145 reaches the discharge semicircular rod groove 46, it can be rotated downward into the through groove to avoid affecting the passing area of ​​the discharge semicircular rod groove 46.

[0063] A method for using a silicon crystal rod grinding and processing device comprises the following steps:

[0064] S1. Use an external motor to drive the rotating column 2 to rotate, and place the silicon crystal rod to be ground on the upper side of the shell 1. When the semi-circular rod discharge groove 46 and the semi-circular rod placement groove 45 are aligned, the two form a complete cylindrical groove body, and the silicon crystal rod falls into it.

[0065] S2. The rotating rotating column 2 drives the slide 42 and the silicon crystal rod to perform circular motion. During this process, the silicon crystal rod moves from being placed in the semi-circular rod groove 45 to contacting the inner wall of the shell 1 and is pushed back by it, thereby squeezing the slide 42 and compressing the spring 43 to retract into the slide groove 41, that is, the silicon crystal rod is pressed against the inner wall of the shell 1 by the slide 42.

[0066] S3. The silicon crystal rod is driven by the shell 1 to rotate with the circular motion, so that the silicon crystal rod rubs in the grinding semi-circular rod groove 44 to achieve grinding. When the grinding semi-circular rod groove 44 reaches the discharge semi-circular rod groove 46, the silicon crystal rod is pushed into the discharge semi-circular rod groove 46 and falls down to be discharged.

[0067] S4, the silicon crystal rod contacts the coarse grinding block 478 in the grinding semi-circular rod groove 44, and is coarsely ground while rotating. As the outer diameter of the silicon crystal rod decreases after grinding, the slide 42 moves toward the inner wall of the shell 1 to fill the position. During this process, the rack 475 pulls the toothed disc 472 to rotate along the gear 473, and the toothed disc 472 uses the half gear ring 4713 to drive the gear column 4711 and the roller 477 to rotate, so that the coarse grinding block 478 on the surface of the roller 477 is switched to the fine grinding block 479, and after further grinding, the roller 477 continues to rotate to switch to the fine grinding block 4710.

[0068] S5. When the slide 42 is squeezed and inserted by the silicon crystal rod, the rack 475 is pushed into the insertion hole 47142 by the slide 42, so that the rotating shaft 47141 squeezes the top spring 47143 and is locked by the latch 47144. When the slide 42 slides outward, the locked rotating shaft 47141 and the rack 475 can pull the gear 473 to switch the grinding block. When the grinding semicircular rod groove 44 is aligned with the semicircular rod groove 46 to release the silicon crystal rod, the silicon crystal rod presses down the seesaw 47145, so that it pushes the moving pin 47147 to move upward. The top end of the moving pin 47147 pushes the rotating shaft 47141 to rotate along the notch 47148. At this time, the latch 47144 is dislocated to release the lock, and the top spring 47143 pushes the rotating shaft 47141 to slide outward and rotate for double reset.
