Description

Technical Field

[0001] The utility model belongs to the field of silicon rod placement, in particular to a single crystal silicon rod placement block. Background Art

[0002] The current solution is that the placement devices for round and square ingots are incompatible, requiring each size of ingot to be stored separately. However, this solution suffers from drawbacks such as waste from multiple handling and transfers and incompatibility with compatible storage. These drawbacks and drawbacks arise from the wide variety of ingot products (classified by size: diameter, margin, etc.; and by shape: round, square, rectangular, half-ingot, etc.).

[0003] There is an existing related patent, patent number CN201821847627.0, "A silicon rod placement trolley", which has the characteristics of "facilitating the transfer and transportation of silicon rods in different process workshops during actual production, and reducing the labor intensity of workers", but it still has some shortcomings. The spacing between its two positioning bosses or the spacing between the two inclined side surfaces cannot be adjusted, and cannot adapt to silicon rods of different specifications, resulting in it being unable to quickly adjust according to the different sizes of silicon rods to be transported. If larger silicon rods are forcibly transported, the contact surface will change and the contact area will also become smaller, which will lead to poor stable deformation during placement, so that it cannot meet diversified transportation needs. Therefore, a single crystal silicon rod placement block is proposed. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the following technical problems in the existing technology: the spacing between the two positioning bosses or the spacing between the two inclined side surfaces cannot be adjusted, and cannot adapt to silicon rods of different specifications, resulting in the inability to quickly adjust according to the different sizes of silicon rods to be transported. If larger silicon rods are forcibly transported, the contact surface will change and the contact area will become smaller, which will lead to poor stable deformation during placement, and thus cannot meet the problem of diversified transportation needs.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a single crystal silicon rod placement block, comprising a placement block assembly, wherein the placement block assembly comprises two placement blocks;

[0007] The placement block includes a bearing seat, a limit platform, a bolt slot and an abutting inclined surface. The upper side of the bearing seat is a flat horizontal surface. A limit platform is provided on one side of the top of the bearing seat. The other side of the top of the bearing seat is milled into an inclined surface. The angle between the inclined surface and the horizontal plane is in the range of 20° to 30°. Two vertical bolt slots are opened through the middle of the bearing seat.

[0008] The bolt slot includes a nail embedding slot and a connecting slot 1, wherein the bottom end of the nail embedding slot is provided with a connecting slot 1, the central axes of the nail embedding slot and the connecting slot 1 coincide with each other, the length of the nail embedding slot is three times that of the connecting slot 1, and the diameter of the connecting slot 1 is two-thirds of the diameter of the nail embedding slot;

[0009] A placement block is installed at each end of the side surface of the fixed plate, and the spacing between the abutting inclined surfaces on the two placement blocks is smaller than the spacing between the limit platforms on the placement blocks. Several connecting grooves 2 are opened on the fixed plate, and locking bolts are inserted into the embedded nail grooves. The stud part of the locking bolt passes through the connecting groove 1 and is threadedly connected to the connecting groove 2.

[0010] As a preferred technical solution for a single crystal silicon rod placement block, the limiting platform is in the shape of a long strip. The limiting platform cooperates with the upper side of the supporting seat to clamp the square silicon rod or the half-rectangular silicon rod, and the supporting seat is in contact with the vertical surface of the square silicon rod or the half-rectangular silicon rod.

[0011] By adjusting the distance between the two bearing seats, the clamping requirements of square silicon rods or half rectangular silicon rods of different sizes can be met.

[0012] As an optimal technical solution for a single crystal silicon rod placement block, the abutting inclined surface on the placement block abuts against the round silicon rod, and a rubber pad is provided on the abutting inclined surface, and the rubber pad abuts against the round silicon rod;

[0013] The rubber pad can be deformed to increase the contact area between the bracket and the outer peripheral surface of the round silicon rod, so that the round silicon rod can be placed more stably.

[0014] As an optimal technical solution for placing a single crystal silicon rod block, the specifications of the round silicon rods include G12, M10 and M6.

[0015] As an optimal technical solution for placing a single crystal silicon rod block, the specifications of the square silicon rod include G12, M10 and M6, and the A1 is a half-rectangular silicon rod.

[0016] The beneficial effects of a single crystal silicon rod placement block of the utility model are as follows: through the cooperation of the supporting seat and the fixed plate, the distance between the two supporting seats can be adjusted to meet the clamping requirements of square silicon rods or half-rectangular silicon rods of different sizes, and the contact angles of the round silicon rods and the placement block are always kept the same, and the contact area between the rectangular silicon rods and the placement block is kept larger, thereby making the silicon rods more stably placed on the placement block.

The limiting platform 2 is provided on one side of the top of the bearing seat 1. The other side of the top of the bearing seat 1 is milled into an inclined surface. The angle between the inclined surface and the horizontal plane is in the range of 20° to 30°. Two vertical bolt slots 3 are opened through the middle of the bearing seat 1.
