Technical Field
[0001] This utility model relates to the technical field of silicon single crystal rod splicing devices, and in particular to a silicon single crystal rod splicing device. Background Technology
[0002] Monocrystalline silicon rods are formed by shaping or pulling silicon monocrystalline rods in a furnace through zone melting or Czochralski processes. When extending monocrystalline silicon rods by joining them together, two operators usually hold one monocrystalline silicon rod and join them together with glue to form a longer monocrystalline silicon rod.
[0003] The inventors discovered during routine use of monocrystalline silicon rods that the dimensions of ordinary monocrystalline silicon rods are fixed. When the required size is needed, splicing is required. Generally, two monocrystalline silicon rods are spliced together, which can easily lead to misalignment of the monocrystalline silicon rods, thus causing problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for splicing silicon single crystal rods.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a silicon single crystal rod splicing device, including an operating table, on the surface of the operating table are silicon single crystal rods, and a splicing device is provided on the top of the operating table. The splicing device includes a rectangular plate provided on the top of the operating table, a fixing ring is fixedly connected to the side of the rectangular plate, and a silicon single crystal rod is inserted into the inside of the fixing ring.
[0006] The effect achieved by the above components is as follows: under the action of the fixing ring, the silicon single crystal rod can be fixed to the side of the rectangular plate, thereby achieving the function of splicing rods. When it is necessary to splice the silicon single crystal rods, apply glue to one end of the silicon single crystal rod and connect another silicon single crystal rod to the end of the silicon single crystal rod with glue, thereby achieving the function of splicing silicon single crystal rods.
[0007] Preferably, an air pump is fixedly connected to the top of the rectangular plate, and an air bag is fixedly connected to the inner wall of the fixing ring. The air bag and the air pump are connected by a connecting pipe.
[0008] The effect achieved by the above components is that, under the action of the air pump, the airbag can be inflated and deflated, thereby fixing silicon single crystal rods of different sizes.
[0009] Preferably, rubber blocks are fixedly connected to the surface of the airbag, and the rubber blocks are evenly arranged on the surface of the airbag.
[0010] The effect achieved by the above components is that, under the action of the rubber block, the silicon single crystal rod will not rotate or move on the surface of the air bag, thereby avoiding displacement.
[0011] Preferably, one end of the fixing ring is fixedly connected to an arc-shaped plate, a rectangular rod is slidably connected to the surface of the arc-shaped plate, a circular groove is formed on the surface of the rectangular rod, a locking rod is inserted into the side of the arc-shaped plate, and a support ring is fixedly connected to one end of the rectangular rod.
[0012] The effect achieved by the above components is that the rectangular rod can be fixed under the action of the clamp, thereby supporting the silicon single crystal rod and thus achieving the function of supporting the silicon single crystal rod.
[0013] Preferably, a spring is sleeved on the surface of the clamp rod, and the two ends of the spring are fixedly connected to one end of the clamp rod on the side of the arc plate.
[0014] The aforementioned components achieve the following effects: Under the action of the spring, the locking rod will not slip out of the circular groove, thus preventing it from slipping out. When splicing silicon single crystal rods, the silicon single crystal rod is inserted into the fixing ring, and the air pump is activated to inflate the airbag, fixing the silicon single crystal rod inside the fixing ring. Under the action of the rubber block, the silicon single crystal rod will not rotate or move on the surface of the airbag, thus avoiding displacement. When the silicon single crystal rod is fixed inside the fixing ring, the locking rod is pulled outward, away from the rectangular rod, and the rectangular rod is moved upward, so that the support ring contacts the silicon single crystal rod. After the support ring contacts the silicon single crystal rod, the locking rod is inserted into the circular groove. Under the action of the spring, the locking rod will not slip out of the circular groove, thus preventing it from slipping out, thereby fixing the silicon single crystal rod. Apply glue to one end of the silicon single crystal rod, and insert the other silicon single crystal rod into the fixing ring and move it to bond the two silicon single crystal rods together, thus achieving the splicing function.
[0015] Preferably, the surface of the operating table is provided with an adjustment device, the adjustment device including a rectangular groove formed on the top of the operating table, a bidirectional screw rotatably connected to the inner wall of the rectangular groove, a slider threadedly connected to the surface of the bidirectional screw, and a rectangular plate fixedly connected to the top of the slider.
[0016] The effect achieved by the above components is that, under the action of the bidirectional screw, the rectangular plates can move relative to each other, thereby making it easier to splice silicon single crystal rods.
[0017] Preferably, a pad, which is a rubber plate, is fixedly connected to the side of the slider.
[0018] The effect achieved by the above components is that, under the action of the pad, the slider will not directly hit the inner wall of the rectangular groove, thus avoiding the phenomenon of the slider being damaged by impact.
[0019] Preferably, the top of the operating table is threaded with a bolt, which abuts against the surface of the bidirectional screw.
[0020] The aforementioned components achieve the following effects: the position of the bidirectional screw can be fixed by the bolt, thus achieving the function of fixing the bidirectional screw. When it is necessary to adjust the position of the rectangular plate, the bolt is rotated in the opposite direction to separate the bolt from the bidirectional screw. The bidirectional screw is then rotated by hand to move the slider relative to it, thereby moving the silicon single crystal rod relative to it. When it is moved to the appropriate position, the bolt is screwed into the surface of the bidirectional screw to fix it. With the help of the pad, the slider will not directly hit the inner wall of the rectangular groove, avoiding damage to the slider. This achieves the function of adjusting the rectangular plate.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting up a splicing device, when silicon single crystal rods need to be spliced, the silicon single crystal rod is inserted into the inside of the fixing ring. The air pump is started to inflate the airbag, fixing the silicon single crystal rod inside the fixing ring. Under the action of the rubber block, the silicon single crystal rod will not rotate or move on the surface of the airbag, thus avoiding displacement. When the silicon single crystal rod is fixed inside the fixing ring, the locking rod is pulled outward, away from the rectangular rod. The rectangular rod is moved upward, so that the support ring contacts the silicon single crystal rod. After the support ring contacts the silicon single crystal rod, the locking rod is inserted into the inside of the circular groove. Under the action of the spring, the locking rod will not slip out of the inside of the circular groove, thus achieving the anti-dislodgement function and fixing the silicon single crystal rod. Glue is applied to one end of the silicon single crystal rod, and the other silicon single crystal rod is inserted into the inside of the fixing ring and moved to bond the two silicon single crystal rods together, thus achieving the splicing function. This solves the problem of misalignment and uneven splicing that easily occurs when the operator holds the single crystal silicon rods by hand. Attached Figure Description

[0027] Example 1, as Figure 1 A splicing device 2 for silicon single crystal rod 1 includes an operating table 4, on the surface of the operating table 4 are silicon single crystal rods 1, and the splicing device 2 is arranged on the top of the operating table 4.
[0028] The working principle is as follows: when it is necessary to splice silicon single crystal rods 1, glue is applied to one end of silicon single crystal rod 1, and another silicon single crystal rod 1 is joined to the end of the silicon single crystal rod 1 coated with glue, thereby achieving the function of splicing silicon single crystal rods 1.
[0029] Reference Figure 2 The splicing device 2 includes a rectangular plate 21 set on the top of the operating table 4. A fixing ring 22 is fixedly connected to the side of the rectangular plate 21. A silicon single crystal rod 1 is inserted into the inside of the fixing ring 22. An air pump 23 is fixedly connected to the top of the rectangular plate 21. An air bag 24 is fixedly connected to the inner wall of the fixing ring 22. The air bag 24 and the air pump 23 are connected by a connecting pipe. Rubber blocks 25 are fixedly connected to the surface of the air bag 24. The rubber blocks 25 are evenly arranged on the surface of the air bag 24. An arc plate 26 is fixedly connected to one end of the fixing ring 22. A rectangular rod 27 is slidably connected to the surface of the arc plate 26. A circular groove is opened on the surface of the rectangular rod 27. A clamping rod 29 is inserted into the side of the arc plate 26. A support ring 28 is fixedly connected to one end of the rectangular rod 27. A spring 210 is sleeved on the surface of the clamping rod 29. The two ends of the spring 210 are fixedly connected to the side of the arc plate 26 and one end of the clamping rod 29, respectively.
[0030] Working principle: When splicing silicon single crystal rods 1, the silicon single crystal rod 1 is inserted into the fixing ring 22. The air pump 23 is started, causing the air bag 24 to inflate, thus fixing the silicon single crystal rod 1 inside the fixing ring 22. Under the action of the rubber block 25, the silicon single crystal rod 1 will not rotate or move on the surface of the air bag 24, thereby avoiding displacement. When the silicon single crystal rod 1 is fixed inside the fixing ring 22, the locking rod 29 is pulled outward, away from the rectangular rod 27, and the rectangular rod 27 is turned upward. The movement causes the support ring 28 to contact the silicon single crystal rod 1. After the support ring 28 contacts the silicon single crystal rod 1, the locking rod 29 is inserted into the inside of the circular groove. Under the action of the spring 210, the locking rod 29 will not slip out of the inside of the circular groove, thus achieving the function of preventing slippage and fixing the silicon single crystal rod 1. Apply glue to one end of the silicon single crystal rod 1, and insert the other silicon single crystal rod 1 into the inside of the fixing ring 22 and move it to bond the two silicon single crystal rods 1 together, thus achieving the function of splicing rods.
[0031] Reference Figure 3 The surface of the operating table 4 is provided with an adjustment device 3. The adjustment device 3 includes a rectangular groove 31 opened on the top of the operating table 4. A double-acting screw 32 is rotatably connected to the inner wall of the rectangular groove 31. A slider is threadedly connected to the surface of the double-acting screw 32. A rectangular plate 21 is fixedly connected to the top of the slider. A pad 34 is fixedly connected to the side of the slider. The pad 34 is a rubber plate. A bolt 33 is threadedly connected to the top of the operating table 4. The bolt 33 abuts against the surface of the double-acting screw 32.
[0032] Working principle: When the position of the rectangular plate 21 needs to be adjusted, the bolt 33 is rotated in the opposite direction to separate the bolt 33 from the bidirectional screw 32. The bidirectional screw 32 is rotated by hand to move the slider relative to the plate, which in turn moves the silicon single crystal rod 1 relative to the plate. When it is moved to the appropriate position, the bolt 33 is screwed into the surface of the bidirectional screw 32 to fix the bidirectional screw 32. With the action of the pad 34, the slider will not directly hit the inner wall of the rectangular groove 31, thus avoiding damage to the slider and achieving the function of adjusting the rectangular plate 21.
