Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor processing, in particular to a wire-drawing tool for squaring a crystal rod. Background Art

[0002] When processing crystal rods, a multi-wire cutting machine is required to cut the round rod into a square rod. During cutting, the diamond wire cuts the outer wall of the round rod from top to bottom. However, after the cutting is completed, since the diamond wire is close to the surface of the square rod, directly taking the square rod without pushing the diamond wire away will cause the surface of the square rod to contact the diamond wire, causing damage to the quality of the square rod. If the diamond wire is manually pushed to form a gap between two adjacent diamond wires, it will be convenient to take out the square rod. However, since the diamond wire is very sharp, workers will be scratched if they are not careful. In serious cases, it may cause physical disability, posing a major safety hazard.

[0003] The patent document with patent announcement number: CN217597507U discloses a protective device for crystal rod squaring, including a group of relatively arranged wire-receiving segments, the wire-receiving segments are arranged under the crystal rod; each of the wire-receiving segments is constructed with a bin for placing diamond wire; the wire-receiving segments can enter the bin when the diamond wire has cut any group of edge materials of the crystal rod, so as to separate the descending edge materials from contacting the diamond wire, and allow the edge materials to slide into the recovery bin through the outer wall surface of the wire-receiving segments. The utility model has a simple structure and does not affect the overall structure of the squarer. Only a suspended wire-receiving bin is arranged on the workbench, so that the diamond wire can be put into the bin for protection when the knife is retracted, so as to prevent the cut edge materials from crushing or cutting the diamond wire, protect the integrity of the diamond wire, and reduce the breakage rate of the diamond wire.

[0004] The wire-receiving segment in the above scheme is placed under the crystal rod, and the crystal rod is generally placed on a flat workbench, which requires the workbench to be modified to meet the installation requirements of the wire-receiving segment, which is bound to increase the cost. Therefore, a wire-splitting tool is needed that does not require modification of the workbench and can automatically separate the diamond wire and the square rod after the crystal rod cutting is completed. Utility Model Content

[0005] In order to overcome the above technical problems, the purpose of the utility model is to provide a wire pulling tool for squaring a crystal rod, which solves the problem that the diamond wire is too close to the surface of the square rod when the crystal rod is squared, resulting in damage to the square rod and breakage of the diamond wire.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A wire-sliding tool for crystal ingot squaring is used to spread the diamond wire after the crystal ingot is squaring, comprising a base and a pusher which rise or fall synchronously with the diamond wire, the pusher can reciprocate with respect to the base, both ends of the base are rotatably connected with a rotating block, a wire-sliding rod is provided on the rotating block, the wire-sliding rod is located on the inner side of the diamond wire, and the rotating block and the pusher are movably connected by a connecting rod.

[0008] Furthermore, the pushing member is a cylinder.

[0009] Furthermore, the pushing member is provided with a first pin, the rotating block is provided with a second pin, and both ends of the connecting rod are rotatably connected to the first pin and the second pin respectively.

[0010] Furthermore, a avoidance groove is formed on a surface of the base facing the connecting rod.

[0011] Furthermore, a strip-shaped through hole is provided on the rotating block, and the wire-moving rod can slide in the strip-shaped through hole.

[0012] Furthermore, a sleeve is rotatably provided on the outside of the wire-shifting lever.

[0013] Beneficial effects of the utility model:

[0014] Compared with the traditional method, this technical solution does not require any improvement to the workbench. It can efficiently push the diamond wire away after the crystal rod is squared and prevent it from contacting the square rod. It can effectively solve the problem of dry cutting caused by the diamond wire touching the wire pusher rod, resulting in sand falling off the steel wire, and poor apparent quality of the square rod. It can thus improve production efficiency, increase product yield, reduce workers' labor intensity and safety risks, and is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a wire-splitting tool for crystal rod squaring is used to spread the diamond wire 3 after the crystal rod squaring process. The initial state of the crystal rod is a round rod 1. During squaring, the machine head is located above the round rod 1, and the diamond wire 3 for cutting is installed at the machine head. When the machine head moves from top to bottom, the diamond wire 3 moves downward synchronously to cut the round rod 1, and the round rod 1 is cut into a square rod 2.

[0029] like Figure 5 , Figure 6As shown, the wire-sliding tooling includes a base 4 and a pusher 5 that rise or fall synchronously with the diamond wire 3. The base 4 and the pusher 5 are both mounted on the machine head. The pusher 5 can reciprocate about the base 4. Both ends of the base 4 are rotatably connected with a rotating block 6. A wire-sliding rod 7 is provided on the rotating block 6. The wire-sliding rod 7 is located on the inner side of the diamond wire 3. The rotating block 6 and the pusher 5 are movably connected through a connecting rod 8. When the pusher 5 moves toward the square rod 2, the pusher 5 drives the rotating block 6 to rotate about the base 4 through the connecting rod 8, and then drives the wire-sliding rod 7 to move. At this time, the wire-sliding rod 7 will flip toward the outer side of the diamond wire 3. In this process, the diamond wire 3 will be pushed away, thereby leaving a gap between the diamond wire 3 and the square rod 2, so as to facilitate the removal of the square rod 2. Similarly, after the pusher 5 is reset, the connecting rod 8 will pull the rotating block 6 to reset, and the wire-sliding rod 7 will retract. When the wire-sliding rod 7 is no longer in contact with the diamond wire 3, the diamond wire 3 will automatically reset, and the crystal rod cutting and square operation can be carried out again under the drive of the machine head.

[0030] In this embodiment, the pusher 5 is a cylinder, and the base 4 is fixed on the machine head. When the wire is dialed, the pusher 5 can move toward the square rod 2 or away from the square rod 2, thereby driving the connecting rod 8 and the rotating block 6 to move.

[0031] like Figure 6 , Figure 7 , Fig. 9 As shown, in this embodiment, the pusher 5 is provided with a pin 1 51, the rotating block 6 is provided with a pin 2 81, the two ends of the connecting rod 8 are rotatably connected with the pin 1 51 and the pin 2 81 respectively, the two connecting rods 8 are staggered up and down, and the length of the pin 1 51 is greater than the thickness of the two connecting rods 8 superimposed together;

[0032] When the pushing member 5 moves toward the square rod 2, the two connecting rods 8 gradually change from a folded state to a horizontal state. At this time, the two rotating blocks 6 rotate synchronously and the distance between them increases. The rotating block 6 flips toward the outside of the diamond wire 3, and the wire-moving rod 7 moves the diamond wire 3 to leave a gap between the diamond wire 3 and the square rod 2; and when the pushing member 5 is reset, since the avoidance groove 41 is formed on the side of the base 4 facing the connecting rod 8, the two connecting rods 8 are folded and retracted into the avoidance groove 41.

[0033] like Figure 7 As shown, a strip through hole 61 is provided on the rotating block 6, and the wire-moving rod 7 can slide in the strip through hole 61. When the diamond wire 3 is moved, the wire-moving rod 7 will first slide in the strip through hole 61 until the wire-moving rod 7 slides to the end of the strip through hole 61. When the pushing member 5 moves further, the wire-moving rod 7 will move the diamond wire 3 away, thereby cooperating with the movement stroke of the pushing member 5 to achieve a better wire-moving opportunity.

[0034] Embodiment 2:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, a wire-splitting tool for crystal ingot squaring is used to spread the diamond wire 3 after the crystal ingot squaring process, including a base 4 and a pusher 5 that rise or fall synchronously with the diamond wire 3. The base 4 and the pusher 5 are both mounted on the machine head, and the pusher 5 can move about the base 4. Compared with the first embodiment, the difference of this embodiment is that:

[0036] like Figure 8 As shown, a sleeve 9 is rotatably provided on the outside of the wire-moving rod 7, and the sleeve 9 is made of polyurethane material. Since the diamond wire 3 is in a reciprocating cutting state, by arranging a rotatable sleeve 9 on the outside of the wire-moving rod 7, when in contact with the diamond wire 3, it can prevent the diamond wire 3 from being dry-cut due to the wire-moving rod 7 not being fully extended and retracted, resulting in sand stripping and damage to the diamond wire 3, thereby affecting the processing quality of the crystal rod; since the sleeve 9 is rotatable, even if the diamond wire 3 is dry-cut with the sleeve 9, the sleeve 9 will unload the force by rotating, and will not cause damage to the diamond wire 3, thereby improving the yield rate of the square rod 2.
