DETAILED DESCRIPTION

[0037] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0038] The embodiment of the present invention provides a crystal rod re-cutting device, such as Figure 1 As shown, it includes: a body 1, a cutting component 2 and a feeding component 3, the cutting component 2 is configured as a diamond wire cutter, the feeding component 3 includes a feeding conveyor belt 4 and a feeding guide rail 5, and the feeding guide rail 5 is used to clamp the crystal rod from the feeding conveyor belt 4 and transport it to the cutting component 2 for cutting.

[0039] The working principle and beneficial technical effects of the above technical solution are as follows: when the re-cutting equipment is used, the single crystal silicon square rod is placed on the feeding conveyor 4 for transportation, and then the feeding guide rail 5 clamps the single crystal silicon square rod and transports it to the diamond wire cutter for cutting, thereby automatically completing the fixation and transportation of the silicon rod, thereby improving the cutting efficiency.

[0040] In one embodiment, Figure 2 As shown, the feeding conveyor belt 4 includes a belt body 41, a push block 42 and a supporting slide bar 43. The belt body 41 is horizontally arranged and a plurality of push blocks 42 are arranged on the belt body 41 at equal intervals. Two supporting slide bars 43 are symmetrically arranged on both sides of the belt body 41. The supporting slide bars 43 are horizontally arranged, and the upper edge of the supporting slide bar 43 is higher than the upper edge of the belt body 41.

[0041] The feeding guide rail 5 comprises:

[0042] First guide plates 51: two first guide plates 51 are symmetrically arranged on the bottom wall and the top wall of the machine body 1, and the first guide plates 51 slide horizontally under the drive of the first driving electric cylinder 52;

[0043] A second slide bar 53, two second slide bars 53 are symmetrically arranged on the first guide plate 51, the second slide bars 53 are arranged horizontally and the length direction is perpendicular to the sliding direction of the first guide plate 51, and a second slide groove 54 is opened on the second slide bar 53 along the length direction;

[0044] A third slide bar 55 is provided on the second slide bar 53. The third slide bar 55 is vertically provided, and the end of the third slide bar 55 is slidably provided in the second slide groove 54. The third slide bar 55 slides along the second slide groove 54 under the drive of the second driving electric cylinder 56. A third slide groove 57 is provided on the third slide bar 55 along the length direction;

[0045] A fixed rod 58 is arranged between the two third sliding rods 55.

[0046] The working principle and beneficial technical effects of the above technical solution are as follows: when in use, the silicon rod is placed on the supporting slide bar 43, and the movement of the belt body 41 drives the push block 42 to move together. The upper end of the push block 42 abuts against the silicon rod and pushes the silicon rod to slide forward along the supporting slide bar 43. At the same time, since the push blocks 42 are arranged at equal intervals, the material transportation time during the feeding process can be guaranteed to be stable; then the clamping claws 6 on the fixed rod 58 clamp the silicon rod from the upper and lower sides at the same time, and then the third driving electric cylinder 59 drives the fixed rod 58 and the clamping claws 6 to move upward together, and then the second driving electric cylinder 56 drives the third slide bar 55 and the fixed rod 58 to move horizontally together to approach the diamond wire cutter for cutting. When a section of cutting is completed, the first driving electric cylinder 52 drives the first guide plate 51 and the feeding guide rail 5 to move horizontally as a whole, so that the silicon rod moves axially to cut the next section. Through the above arrangement, the cutting length of each section can also be freely controlled, ensuring the practicality of the device.

[0047] In one embodiment, an observation window made of a transparent material is provided on the side wall of the body 1 .

[0048] The working principle and beneficial technical effects of the above technical solution: the setting of the observation window not only ensures the smooth progress of the cutting process and can protect the safety of the operator, but also makes it easy to understand the cutting progress in real time, thereby improving the practicability of the device.

[0049] In one embodiment, Figure 3 As shown, a dust removal component 7 is also provided on the side wall of the machine body 1, and the dust removal component 7 includes an exhaust pipe 71 and an exhaust fan 72. The side wall of the machine body 1 is connected with the exhaust pipe 71, and the exhaust fan 72 and an exhaust motor 73 are provided in the exhaust pipe 71. The exhaust motor 73 is used to drive the exhaust fan 72 to rotate:

[0050] The dust removal assembly 7 also includes a bag dust removal assembly 74, and the bag dust removal assembly 74 includes a dust removal box 75. The exhaust pipe 71 is connected to the dust removal box 75. A plurality of dust removal filter cloths 76 are arranged at equal intervals in the dust removal box 75. The dust removal filter cloths 76 are arranged vertically and the top is connected to the bottom wall of the dust removal box 75. The bottom of the dust removal box 75 is provided with a sewage outlet 77;

[0051] The dust removal box 75 is also provided with an oscillating dust cleaning component 8, and the oscillating dust cleaning component 8 includes:

[0052] A limiting shaft 81 is provided on the side wall of the dust removal box 75, and the limiting shaft 81 is coaxially arranged with the output shaft of the exhaust motor 73;

[0053] An oscillating sleeve 82 is sleeved on the limiting shaft 81. The oscillating sleeve 82 is coaxially arranged with the limiting shaft 81, and an oscillating spring 83 is arranged between the oscillating sleeve 82 and the side wall of the dust removal box 75;

[0054] An oscillating push block 84 is provided at the end of the output shaft of the exhaust motor 73. The oscillating push block 84 is arranged in a triangular structure. An end of the oscillating sleeve 82 close to the exhaust motor 73 is provided with an engaging groove 85 along the circumferential direction. The engaging groove 85 is arranged in a triangular structure, and the edges of the engaging groove 85 and the oscillating push block 84 are arranged in an arc structure.

[0055] Oscillating nets 86, a plurality of oscillating nets 86 are arranged on the oscillating sleeve 82 at equal intervals, and the oscillating nets 86 abut against the dust filter cloth 76;

[0056] The sewage outlet 77 is configured as a funnel-shaped structure.

[0057] The working principle and beneficial technical effects of the above technical solution: When the dust removal component 7 is used, the exhaust motor 73 starts to drive the exhaust fan 72 to rotate, so as to extract the silicon powder generated by cutting with the airflow, so as to prevent the silicon powder from scattering randomly and causing harm to the health of the staff. Then the silicon powder enters the dust removal box 75 with the airflow, and the silicon powder is filtered out and falls from the sewage outlet 77 when the airflow passes through the dust filter cloth 76, completing the filtration and collection of silicon powder. At the same time, the lower end of the oscillation sleeve 82 is pushed by the oscillation spring 83 and abuts against the oscillation push block 84 at the end of the output shaft of the exhaust motor 73. At this time, as the exhaust motor 73 rotates, the oscillation push block 84 repeatedly slides in and out of the fitting groove 85, thereby pushing the oscillation sleeve 82 to slide back and forth along the axial direction, thereby driving the oscillation net to reciprocate and hit the dust filter cloth 76, so that the silicon powder on the surface of the dust filter cloth 76 falls off. The specific user oscillation net is set to metal or hard plastic material.

[0058] In one embodiment, Figure 4 As shown, a scraping assembly 9 is provided at the sewage outlet 77 in the dust removal box 75, and the scraping assembly 9 includes:

[0059] A support plate 901 is provided at the sewage outlet 77, the support plate 901 is vertically arranged, a scraping motor 902 is arranged on the support plate 901, the output shaft of the scraping motor 902 is horizontally arranged, and a first crank 903 is arranged on the output shaft of the scraping motor 902, a second crank 904 is arranged at the end of the first crank 903, and the first crank 903 is hinged to the middle of the second crank 904;

[0060] A scraping spindle 905 is provided at the sewage outlet 77. The scraping spindle 905 is vertically arranged. The lower end of the scraping spindle 905 is hinged to the middle of the second crank 904 through a third crank 906. Two scraping rods 907 are symmetrically arranged at the upper end of the scraping spindle 905. The scraping rod 907 is obliquely arranged downward and one end is hinged to the scraping spindle 905. A scraper blade 908 is arranged at the lower end of the scraping rod 907.

[0061] A scraping sleeve 909, the scraping main shaft 905 is coaxially sleeved with the scraping sleeve 909, and the scraping main shaft 905 is axially slidably connected to the scraping sleeve 909, two fourth cranks 910 are symmetrically arranged on both sides of the scraping sleeve 909, one end of the fourth crank 910 is hinged to the scraping sleeve 909, and the other end of the fourth crank 910 is hinged to the middle of the scraping rod 907, and the lower end of the scraping sleeve 909 is hinged to one end of the second crank 904 through a fifth crank 911;

[0062] A sixth crank 912 is hingedly connected to the other end of the second crank 904 . A positioning boss 913 is provided obliquely above the scraping motor 902 . The sixth crank 912 is hingedly connected to the positioning boss 913 .

[0063] The working principle and beneficial technical effects of the above technical solution are as follows: when the scraper assembly 9 is in use, the scraper blade 908 at the front end of the scraper rod 907 abuts against the inner wall of the funnel-shaped structure at the bottom of the dust removal box 75, and the scraper motor 902 is started to drive the first crank 903 to rotate, thereby driving the second crank 904 to swing. At this time, the second crank 904 forms a lever structure. When the first crank 903 rotates downward, the second crank 904 swings downward together, thereby driving the scraper spindle 905 and the scraper sleeve 909 to move downward together. The scraper blade 908 at the front end of the scraper rod 907 scrapes the silicon powder on the inner wall at the bottom of the dust removal box 75 At this time, due to the limitation of the sixth crank 912, the end of the second crank 904 connected to the sixth crank 912 will tilt upward during the overall downward swinging of the second crank 904, thereby causing the other end of the second crank 904 to tilt downward, that is, the downward movement speed of the fifth crank 911 is greater than that of the third crank 906, thereby causing the downward movement speed of the scraper sleeve 909 to be greater than that of the scraper shaft 905, that is, the scraper sleeve 909 moves downward relative to the scraper shaft 905. At this time, the fourth crank 910 drives the two scraper main rods to approach each other, thereby preventing the scraper rod 907 from being unusable due to the gradual reduction in the diameter of the sewage outlet 77.

[0064] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
