Embodiment 1

[0044] Fixtures for handling monocrystalline silicon rods, used for moving or transferring single crystal silicon rods, or moving or transferring other columnar materials.

[0045] Such as figure 1 , the fixture includes a mounting base 1, and a clamping arm 2 is rotatably connected to the mounting base 1. There are two clamping arms 2, and the two clamping arms 2 are symmetrically arranged so that the two clamping arms 2 clamp the object to be clamped. .

[0046] Such as figure 1 , a pressing block 3 is also provided on the mounting seat 1, the pressing block 3 is located between the clamp arms 2, and the pressing block 3 reciprocates in a direction approaching and away from the mounting seat 1 .

[0047] Such as figure 1 A connecting rod 4 is arranged between the clamp arm 2 and the pressing block 3, one end of the connecting rod 4 is rotatably connected to the clamp arm 2, and the other end of the connecting rod 4 is rotatably connected to the On the pressing block 3, ...

Embodiment 2

[0052] This embodiment is an optimized solution for the clamp arm 2, which can be combined with Embodiment 1.

[0053] Such as figure 1 , the clamp arm 2 is provided with a buffer sheet 6, the buffer sheet 6 is arranged at the end of the clamp arm 2 away from the mounting base 1, and the buffer sheet 6 is provided with an enlarged buffer sheet 6 patterns of friction coefficient. The buffer sheet 6 is in contact with the clamped object, and clamps the clamped object.

[0054] The buffer sheet 6 can be made of rubber material, or other soft materials, so as to prevent the buffer sheet 6 from damaging the clamped object.

[0055] The buffer sheet 6 is adhered to the clamp arm 2 . The buffer piece 6 can also be fixed on the clip arm 2 by other means.

Embodiment 3

[0057] This embodiment introduces the compression block 3, which can be combined with Embodiment 1 or Embodiment 2.

[0058] Such as figure 1 , The pressing block 3 is provided with a V-shaped groove 7, and the V-shaped groove 7 is arranged on the side of the pressing block 3 in contact with the object to be clamped.

[0059] The function of the V-shaped groove 7 will be specifically introduced below through the shape of the clamped object.

[0060] Such as Figure 4 , when the clamped object is cylindrical, the side wall of the V-shaped groove 7 is in contact with the side wall of the clamped object to position the clamped object, and cooperate with the clamp arm 2 to realize three-point positioning of the clamped object.

[0061] Such as Figure 5 , when the shape of the object to be clamped is prismatic, one edge of the object to be clamped cooperates with the V-shaped groove 7, that is, a part of a ridge line of the object to be clamped is located in the V-shaped groove...

Abstract

The invention discloses a clamp for carrying a monocrystalline silicon rod. The clamp for carrying the monocrystalline silicon rod is used for solving the technical problem that the positioning strength of a clamping jaw on the silicon rod is low in the prior art. According to the clamp for carrying the monocrystalline silicon rod, clamping arms are rotationally connected to a mounting base, a pressing block is arranged on the mounting base, moreover, the pressing block does reciprocating motion in the directions away from and close to the mounting base, connecting rods are arranged between the clamping arms and the pressing block, one ends of the connecting rods are rotationally connected to the pressing block, and the other ends of the connecting rods are rotationally connected to the clamping arms; the pressing block does reciprocating motion and drives the clamping arms to be opened or clamped through the connecting rods, when the clamping arms clamp an clamped object, the pressingblock makes contact with the clamped object, namely, three-point positioning on the clamped object is realized when the clamped object is clamped through the clamp, so that the clamp has higher positioning strength on the clamped object, the stability of the silicon rod in the process of transferring the silicon rod is improved, and the performance of the clamp is optimized.

Description

technical field [0001] The invention relates to an auxiliary tool for silicon chip production, in particular to a clamp for handling single crystal silicon rods, and belongs to the field of clamps. Background technique [0002] Monocrystalline silicon is an important semiconductor material or photovoltaic material, which is widely used in the prior art. For example, in the production process of monocrystalline silicon wafers, the monocrystalline silicon material is first made into silicon rods, and then the silicon rods are cut into silicon wafers by multi-wire cutting equipment for subsequent use. Therefore, silicon rods need to be handled during the production process of silicon wafers. [0003] When transferring the silicon rods in the prior art, the silicon rods are generally transferred by manual handling. This operation method causes labor intensity of the operators, and in addition, the silicon rods are easily damaged during the manual handling process. For this rea...
