[0029] Example:

[0030] See Figure 1 and Figure 2 This embodiment discloses a lifting mechanism suitable for crystal rods of various specifications, including a frame 10, a lifting component 20 and a support component 30. The lifting component 20 is disposed on the frame 10 and has a lifting end that can reciprocate in the vertical direction. The support component 30 is disposed on the lifting end of the lifting component 20.

[0031] Specifically, the support assembly 30 includes multiple pairs of roller groups 31, all of which are able to rotate freely around their axes. All roller groups 31 are arranged on the same plane, and are arranged in a row at equal intervals. The axes of all roller groups 31 are parallel to each other.

[0032] Each pair of roller groups 31 includes two rollers 32, which are conical in shape. The two rollers 32 in each pair of roller groups 31 are symmetrically arranged, and the ends of the two rollers 32 with smaller end areas are close to each other, with a gap between the two rollers 32.

[0033] In this embodiment, the polycrystalline silicon ingot has a cylindrical structure. During operation, the lifting component 20 drives the support component 30 and the ingot to move in the vertical direction. Multiple conical rollers on the support component 30 increase the contact area between the rollers and the surface of the ingot, thereby keeping the ingot in a stable state and preventing it from shifting.

[0034] In one specific embodiment:

[0035] The support assembly 30 also includes a main shaft 33 and a support plate 34. There are two support plates 34, both of which are installed on the lifting end of the lifting assembly 20.

[0038] Preferably, the surface of the roller 32 is a concave arc-shaped structure, thereby increasing the contact area between the roller 32 and the crystal rod.

[0039] In another specific embodiment:

[0040] A wedge 40 is provided between the lifting assembly 20 and the support assembly 30, and the top surface of the wedge 40 is an inclined surface structure. By installing the wedge 40 between the support assembly 30 and the lifting assembly 20, the crystal ingot is tilted at a certain angle during the lifting process, which can prevent the material from slipping off the loading rack of the squaring machine.

[0041] Preferably, the inclination angle of the lower top surface is less than 15°.

[0043] The lifting assembly 20 includes a cylinder 21, the cylinder body of which is mounted on the frame 10, and the piston rod of the cylinder 21 is the lifting end of the lifting assembly 20.

[0044] Preferably, a mounting plate 22 is provided on the top of the frame 10, and the cylinder 21 is mounted on the mounting plate 22.

[0045] The support assembly 30 has a base plate at its bottom, and multiple guide rods 23 are vertically downward at the bottom of the base plate. The mounting plate 22 has guide holes that match the guide rods 23.

[0046] In this embodiment, the support assembly 30 is driven to move up and down by the cylinder 21, and the cylinder 21 is mounted on the frame 10 by the mounting plate 22. By setting multiple guide rods 23 and guide holes, the movement trajectory of the support assembly 30 is restricted.
