Description

Technical Field

[0001] The utility model relates to the technical field of silicon rod processing and production, in particular to a silicon rod processing cutting device which is convenient for personnel to adjust. Background Art

[0002] Silicon rods are a key step in the production of monocrystalline silicon wafers. They have strict requirements on production equipment and processes, and need to be continuously and uninterruptedly pulled at high temperatures before they can be "pulled out of the furnace". The first large-sized monocrystalline silicon rod produced by Shuangliang Silicon Materials R&D Center is shaped like a giant cylindrical pen, with a bright silver surface that shines brightly. The successful production of Shuangliang Energy Saving's first large-sized monocrystalline silicon rod is of great significance to the subsequent Shuangliang Energy Saving Baotou monocrystalline silicon project to improve the process level and smoothly put it into production. Silicon rods need to be cut during the processing and production process.

[0003] At present, most of the existing cutting devices have a relatively simple structure, and only clamp the two ends of the silicon rod by clamping and positioning. Due to the different models of silicon rods to be produced and processed, the diameters of the silicon rods are also different. Most of the clamps of the existing cutting devices can only adapt to the size of the silicon rods currently being processed, and cannot adapt to other silicon rods of different sizes. Personnel may need to choose a variety of different types of cutting devices and clamps to adapt to a variety of silicon rod sizes, which increases a certain amount of production costs and further reduces the practicality of the cutting device. Therefore, we propose a cutting device for silicon rod processing that is easy for personnel to adjust to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

Specifically, personnel can clamp and position the outside of both sides of the silicon rod placed between the two arc plates 14 through the positioning component, and at the same time, clamp and position the two ends of the silicon rod through the clamping component. The operation is convenient and the effect is obvious, which reduces the production cost and improves the practicability of processing and cutting. The cutting mechanism 6 is the cutting machine body, which is connected through an external controller and a power supply. It is a prior art and will not be described here.

[0025] Furthermore, the clamping assembly includes a limiting groove opened in the middle of the top of the base plate 1, and a bidirectional screw rod 4 is arranged above the base plate 1. One end of the bidirectional screw rod 4 is rotatably connected to the inner wall of one end of the connecting plate 2, and the other end of the bidirectional screw rod 4 passes through the side wall of the adjacent connecting plate 2 and is fixedly installed with a turning handle 3. Specifically, through the setting of the turning handle 3, a person can rotate the bidirectional screw rod 4 by holding the turning handle 3, and then can adjust and move the two clamping plates 8.

[0026] Furthermore, the clamping assembly also includes two screw sleeves 5 which are sleeved on the two ends of the outside of the bidirectional screw rod 4. The top of the outer ring of the two screw sleeves 5 is fixedly connected to the bottom of the adjacent clamping plate 8. The bottom of the outer ring of the two screw sleeves 5 is fixedly connected with a limit block 7 adapted to the limit groove. Specifically, through the setting of the screw sleeve 5, the two-way screw rod 4 rotates, and the two screw sleeves 5 produce lateral displacement towards or away from each other, which then drives the clamping plate 8 on the top of the outer ring of the screw sleeve 5 to move together, thereby clamping the two ends of the silicon rod placed between the two clamping plates 8, and adapting to silicon rods of different lengths to a certain extent.

[0027] Furthermore, the two ends of the bottom of the connecting plate 2 are fixedly connected to the two sides of the top of the bottom plate 1, and the inner arc surfaces of the two arc plates 14 are fixedly installed with protective pads 15. Specifically, through the setting of the protective pads 15, the protective pads 15 can protect the outside of the silicon rod when it is clamped, so as to prevent the arc plate 14 from clamping too hard and damaging the outer surface of the silicon rod.

[0028] Furthermore, the positioning assembly includes a mounting plate 9 arranged on one side of the clamping plate 8, and the mounting plate 9 is U-shaped, and the side walls at both ends of the mounting plate 9 are fixedly connected to the side walls of the clamping plate 8, and the outer arc surfaces of the two arc-shaped plates 14 are fixedly connected to short rods 13, and a pull rod 10 is provided inside the mounting plate 9, one end of the pull rod 10 passes through the side wall of the clamping plate 8 and is fixedly connected to one end of one of the short rods 13 away from the arc-shaped plate 14, and the other end of the short rod 13 away from the arc-shaped plate 14 is fixedly connected to the inner wall of one side of the clamping plate 8, and the other end of the pull rod 10 passes through the side wall of the mounting plate 9 and is fixedly installed with a pull block 11, and a spring 12 is provided on the outside of the pull rod 10, and the two ends of the spring 12 are respectively fixedly connected to the pull block 11 and the adjacent side walls of the mounting plate 9 Next, specifically, through the setting of the spring 12, personnel can hold the pulling block 11 to pull the pulling rod 10 to move. At this time, the pulling block 11 stretches the spring 12, and then the pulling rod 10 moves to drive one of the short rods 13 and the adjacent arc plate 14 to move. Then the personnel places the silicon rod between the two arc plates 14, releases the pulling block 11 to make the spring 12 lose its tension and elastically recover to pull the pulling block 11 back to its original position. The pulling block 11 then drives the pulling rod 10 and makes the adjacent short rods 13 and the arc plate 14 return to their original positions, and at the same time cooperates with another arc plate 14 to clamp and position the outside of the silicon rod, thereby effectively clamping and positioning the silicon rod, making it convenient for personnel to adjust and adapt to silicon rods of different diameters and lengths, thereby improving the practicality of the cutting device.

[0029] Furthermore, there are four supporting legs, and the tops of the four supporting legs are fixedly connected to the four corners of the bottom of the base plate 1. Specifically, the overall stability of the entire cutting device is increased by the arrangement of the supporting legs.

[0030] In summary:

[0031] The personnel can drive the bidirectional screw rod 4 to rotate by holding the turning handle 3. As the bidirectional screw rod 4 rotates, the two screw sleeves 5 will produce a lateral displacement towards each other, and then the clamping plate 8 on the top of the outer ring of the screw sleeve 5 will move together, thereby clamping the two ends of the silicon rod placed between the two clamping plates 8 and adapting to silicon rods of different lengths to a certain extent. By holding the pull block 11, the pull rod 10 is pulled to move. At this time, the pull block 11 stretches the spring 12, and then the pull rod 10 moves to drive one of the short rods 13 and the adjacent arc plate 14 to move. Then the personnel places the silicon rod between the two arc plates 14, releases the pull block 11 so that the spring 12 loses its tension and elastically recovers to pull the pull block 11 back. The pull block 11 then drives the pull rod 10 and makes the adjacent short rods 13 and the arc plate 14 return, and at the same time cooperates with another arc plate 14 to clamp and position the outside of the silicon rod, thereby effectively clamping and positioning the silicon rod, making it convenient for personnel to adjust and adapt to silicon rods of different diameters and lengths, reducing production costs, and improving the practicality of the cutting device.
