Description

Technical Field

[0001] The utility model belongs to the technical field of single crystal silicon rod production and processing, and specifically relates to a clamping device for single crystal silicon square rods. Background Art

[0002] Silicon is the most common and widely used semiconductor material. When molten elemental silicon solidifies, silicon atoms arrange into a crystal nucleus in a diamond lattice, and its crystal nucleus grows into grains with the same crystal plane orientation, forming single crystal silicon.

[0003] The prior art (publication number: CN217122911U) discloses a silicon rod clamping and fixing device for single crystal silicon rod production, belonging to the technical field of silicon rod production clamping instruments. The main points of its technical solution include a bottom plate, and two left - right distributed sliding grooves are penetrated through the upper end surface of the bottom plate.

[0004] The prior art clamps the silicon rod on the device through the symmetric clamps on the device and then cuts it with a cutting machine. Although the prior art can clamp the silicon rod, when the square silicon rod is placed on its top, if the center of the silicon rod does not correspond to the center of the device, there is a high probability that the silicon rod will slip between the clamps during clamping, resulting in an increase in cost. Therefore, the conditions for clamping the silicon rod in the prior art are relatively harsh and it is rather troublesome to fix the silicon rod.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0006] To solve the above - mentioned technical problem of rather troublesome silicon rod clamping, the basic concept of the technical solution adopted by the present utility model is:

[0009] A base block, the base block is fixedly connected to the top of the operating table;

[0010] A clamping structure, the clamping structure is arranged on the top of the operating table for clamping the single crystal silicon square rod. The clamping structure includes: a base rod and clamping blocks. The base rod is fixedly connected to the top of the base block, the clamping blocks are slidably connected to the top of the base rod, and the clamping blocks are symmetrically arranged on the top of the base rod.

[0011] As a preferred embodiment of the present utility model, the base blocks are symmetrically arranged on both sides of the top of the operating table, the bottom of the base rod is fixedly connected to each pair of symmetric base blocks on each side at the same time, the clamping blocks are symmetrically arranged on the top of the base rod, the top of the clamping blocks is in a slope shape, and the lowest point of the slope at the top of the clamping block is on the wall surface of the clamping block facing the other clamping block.

[0012] As a preferred embodiment of the present utility model, the clamping structure further includes a chute, a retractable rod, a slider, and a clamping groove. The chutes are symmetrically formed at the top of the base rod. The retractable rods are fixedly connected within the chutes. The sliders are slidably connected within each chute. One end of the retractable rod is fixedly connected to the wall surface of the slider. The top of the slider is fixedly connected to the bottom of the clamping block. The clamping grooves are formed on the mutually facing wall surfaces of the symmetric clamping blocks, and the clamping grooves are arc-shaped grooves.

[0013] As a preferred embodiment of the present utility model, the slider can slide within the chute. Each chute is provided with a slider and a retractable rod. The chute is an L-shaped groove, and the chute can adapt to the size of the slider. The retractable rod can extend to twice its own length. The extended end of the retractable rod is fixedly connected to the slider, and the extended end of the wall surface of the retractable rod and the retractable rod are elastically connected by a spring.

[0014] As a preferred embodiment of the present utility model, the clamping structure further includes a fixing plate, a screw hole, a locking bolt, and a locking groove. The fixing plate is fixedly connected to one side wall surface of the clamping block. The screw hole is formed through the wall surface of the fixing plate.

[0015] As a preferred embodiment of the present utility model, the locking bolt can pass through the screw hole and enter the locking groove. The wall surface of each clamping block is provided with a fixing plate, a screw hole, and a locking bolt.

[0016] As a preferred embodiment of the present utility model, the base blocks on both sides of the top of the operating table are respectively provided with clamping structures. The two clamping structures are symmetrical to each other, and the top of the load-bearing block is flush with the top of the base rod.

[0017] The present utility model has the following beneficial effects compared with the prior art:

[0018] 1. By setting the clamping structure, the square silicon rod can be directly clamped and adapted. Because the clamping structure automatically adapts to the size of the square silicon rod for clamping through the movable symmetric clamping blocks, and the square silicon rod can be further fixed between the clamping blocks through the locking bolt. This process does not require the special placement of the position of the square silicon rod. Therefore, compared with the prior art, this solution is more convenient and fast when fixing the square silicon rod.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0029] As Figure 1 and Figure 2 shown, a single-crystal silicon ingot clamping device includes:

[0030] An operating table 20, the top of the operating table 20 is fixedly connected with a load-bearing block 21, the top of the load-bearing block 21 is provided with an arc-shaped groove, and the operating table 20 is placed flat on the ground for use;

[0031] A base block 22, the base block 22 is fixedly connected to the top of the operating table 20. This is an existing technology, so it will not be elaborated here.

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a clamping structure, the clamping structure is arranged on the top of the operating table 20 for clamping the single-crystal silicon ingot. The clamping structure includes: a base rod 30 and a clamping block 34. The base rod 30 is fixedly connected to the top of the base block 22, the clamping block 34 is slidably connected to the top of the base rod 30, and the clamping blocks 34 are symmetrically arranged on the top of the base rod 30.

[0033] As Figure 1 , Figure 2 , Figure 3 , Figure 4 andFigure 5 As shown, the base blocks 22 are symmetrically arranged on both sides of the top of the operating table 20. The bottom of the base rod 30 is fixedly connected to the symmetric base blocks 22 on each side at the same time. The clamping blocks 34 are symmetrically arranged on the top of the base rod 30. The top of the clamping block 34 is sloped. The lowest point of the slope at the top of the clamping block 34 is on the wall surface of the clamping block 34 facing the other clamping block 34. The clamping structure further includes a chute 31, a contraction rod 32, a slider 33 and a clamping groove 35. The chutes 31 are symmetrically opened on the top of the base rod 30. The contraction rods 32 are fixedly connected in the chutes 31. The sliders 33 are slidably connected in each chute 31. The wall surface of the slider 33 is also fixedly connected to one end of the contraction rod 32. The top of the slider 33 is fixedly connected to the bottom of the clamping block 34. The clamping grooves 35 are opened on the mutually facing wall surfaces of the symmetric clamping blocks 34. The clamping groove 35 is an arc-shaped groove. The slider 33 can slide in the chute 31. Each chute 31 is provided with a slider 33 and a contraction rod 32. The chute 31 is an L-shaped groove. The chute 31 can adapt to the size of the slider 33. The contraction rod 32 can extend to twice its own length. The extended end of the contraction rod 32 is fixedly connected to the slider 33. The extended end of the wall surface of the contraction rod 32 and the contraction rod 32 are elastically connected by a spring. The clamping structure further includes a fixing plate 40, a screw hole 41, a locking bolt 42 and a locking groove 43. The fixing plate 40 is fixedly connected to a side wall surface of the clamping block 34. The screw hole 41 is penetrated and opened on the wall surface of the fixing plate 40. The locking bolt 42 is threadedly connected in the screw hole 41. The locking groove 43 is opened on the wall surface of the base rod 30 facing the fixing plate 40;

[0034] During specific use, first place the edge of the square silicon rod in the slope of the symmetrical clamping block 34 wall. At this time, rotate the square silicon rod, and the square silicon rod will drive the clamping block 34 to slide through the slope at the top of the clamping block 34. The symmetrical distance between the clamping blocks 34 will increase when the clamping blocks 34 slide. At this time, the square silicon rod will be stuck between the symmetrical clamping blocks 34, and the spring on the wall of the contraction rod 32 will push the extended end of the wall of the contraction rod 32 toward the other clamping block 34. The extended end will drive the slider 33 to move simultaneously in the slide groove 31. The slider 33 will drive the clamping block 34 when moving, so as to clamp the square silicon rod between the symmetrical clamping blocks 34 and the bottom will contact the top of the base rod 30. When the square silicon rod is clamped by the clamping block 34, the middle section of the square silicon rod will be on the load-bearing block 21, after the square silicon rod is clamped, the locking bolt 42 can be manually turned to make the locking bolt 42 pass through the fixing plate 40 and enter the locking groove 43 and press against the wall of the base rod 30 in the locking groove 43, thereby fixing the position of the clamping block 34. At this time, the cutting machine can be used to cut and segment the square silicon rod fixed by the clamping block 34. When the fixed square silicon rod needs to be removed, the locking bolt 42 is first turned to stop the locking bolt 42 from contacting the wall of the base rod 30. At this time, the square silicon rod can be directly taken down from the symmetrical clamping blocks 34. When the square silicon rod is taken out from the clamping blocks 34, the spring on the wall of the contraction rod 32 will push the slider 33 toward the other clamping block 34, thereby driving the symmetrical clamping blocks 34 to return to the original state of contact with each other.

[0035] In summary, by setting up a clamping structure, the square silicon rod can be directly adapted and clamped, because the clamping structure automatically adapts to the size of the square silicon rod for clamping through the movable symmetrical clamping blocks 34, and the square silicon rod can be further fixed between the clamping blocks 34 through the locking bolts 42. This process does not require the special placement of the position of the square silicon rod, so compared with the prior art, this solution is more convenient and quicker in fixing the square silicon rod.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the locking bolt 42 can pass through the screw hole 41 and enter the locking groove 43. The wall surface of each clamping block 34 is provided with a fixing plate 40, a screw hole 41 and a locking bolt 42. The base blocks 22 on both sides of the top of the operating table 20 are respectively provided with clamping structures. The two clamping structures are symmetrical to each other. The top of the load-bearing block 21 is flush with the top of the base rod 30.

[0037] In specific use, the round silicon rod can also be clamped between the symmetrical clamping blocks 34. When the round silicon rod is placed between the symmetrical clamping blocks 34, the clamping groove 35 can adapt to the arc surface of the round silicon rod, and the arc groove on the top of the load-bearing block 21 can also adapt to the bottom arc surface of the round silicon rod, thereby clamping it;

[0038] In summary, by setting the clamping structure, square and cylindrical silicon rods can be clamped. Since the clamping structure adapts to the sizes of the edges of silicon rods with different shapes through the clamping blocks 34 and the clamping grooves 35, it can clamp them, thereby increasing the applicable range of the device.

[0039] Working principle: First, place the edge of the square silicon rod in the slopes on the walls of the symmetric clamping blocks 34. At this time, rotate the square silicon rod. The square silicon rod will drive the clamping blocks 34 to slide through the slopes at the top of the clamping blocks 34. When the clamping blocks 34 slide, the distance between the symmetric clamping blocks 34 will increase. At this time, the square silicon rod will be stuck between the symmetric clamping blocks 34. The spring on the wall of the retractable rod 32 will push the extension end on the wall of the retractable rod 32 towards the other clamping block 34. The extension end will drive the slider 33 to move simultaneously in the chute 31. When the slider 33 moves, it will drive the clamping blocks 34 to clamp the square silicon rod between the symmetric clamping blocks 34 and the bottom contacts the top of the base rod 30. When the square silicon rod is clamped by the clamping blocks 34, the middle section of the square silicon rod will be on the top of the load-bearing block 21. After the square silicon rod is clamped, the locking bolt 42 can be manually turned so that the locking bolt 42 passes through the fixing plate 40 and enters the locking groove 43 and abuts against the wall of the base rod 30 in the locking groove 43 to fix the position of the clamping block 34. At this time, the square silicon rod fixed by the clamping block 34 can be cut into segments in cooperation with the cutting machine. When it is necessary to remove the fixed square silicon rod, first turn the locking bolt 42 to stop the locking bolt 42 from abutting against the wall of the base rod 30. At this time, the square silicon rod can be directly taken out from between the symmetric clamping blocks 34. When the square silicon rod is taken out from between the clamping blocks 34, the spring on the wall of the retractable rod 32 will push the slider 33 towards the other clamping block 34, thereby driving the symmetric clamping blocks 34 to return to the original state of contacting each other.
