Description

Technical Field

[0001] The utility model belongs to the technical field of polysilicon production, and in particular relates to cylindrical flower disc hoisting equipment for polysilicon rods. Background Art

[0002] In the polysilicon production process, due to the heavy weight of polysilicon rods, the disassembly and assembly process of the furnace becomes one of the most labor-intensive processes. Under the requirements of the general environment of the automation industry, domestic and foreign polysilicon manufacturers are actively developing various automated rod disassembly devices in the disassembly and assembly process to reduce manpower consumption and improve labor efficiency.

[0003] At present, most of the polysilicon manufacturers at home and abroad have achieved mechanization in the process of dismantling the reduction furnace. For example, Wacker uses an advanced integrated rod dismantling device, but the cost of the rod dismantling device is relatively high, and it is limited by the structure of the reduction furnace equipment, so it is rarely used; while domestic polysilicon manufacturers all use robotic arms to dismantle the rods. The structure of the robotic arms used is basically similar, and its structure is simple and practical. However, the robotic arms used by most polysilicon manufacturers currently have some mismatches with their actual working conditions, and there is a large gap between the equipment and the actual needs of users. For example, during the process of dismantling the rods, the clamps in the robotic arms cannot dismantle the polysilicon rods from multiple directions, and the adjustable range of the downward flip height of the clamps is small, etc.

[0004] Specifically, since the shape of the polycrystalline silicon rod (referred to as silicon rod) is an inverted U-shape, a silicon rod includes two parallel arms and a crossbeam provided at the top of the two arms for connecting the two arms. The silicon rod can be placed horizontally or vertically. When the silicon rod is placed horizontally, the operator facing the silicon rod sees the silicon rod in an inverted U-shape; when the silicon rod is placed vertically, the operator facing the silicon rod sees the silicon rod in the shape of the number "1". In the existing large-scale reduction furnace, there are generally two types of silicon rods, namely concentric silicon rods (the arrangement of silicon rods is concentric) and honeycomb silicon rods (the arrangement of silicon rods is honeycomb). The concentric silicon rods are placed horizontally, and the honeycomb silicon rods are placed vertically. For the silicon rods in the above two arrangements, due to the limitation of the clamp length in the robotic arm, the existing robotic arm can often only remove the silicon rods placed horizontally, but cannot remove the silicon rods placed vertically, that is, the honeycomb silicon rods can only be removed by manual disassembly. It can be seen that the existing robotic arm cannot remove the silicon rods from multiple directions.

[0005] Since the existing robotic arms can only remove silicon rods placed horizontally, when removing the silicon rods in the reduction furnace arranged in a honeycomb shape, the first 6 pairs of honeycomb silicon rods must be manually disassembled to leave space for changing the position of the robotic arm so that the silicon rods are placed horizontally relative to the robotic arm before the remaining silicon rods can be removed.

[0006] A Chinese patent with publication number CN205928720U and publication date 2017-02-08 discloses a silicon rod mechanical arm, including a bracket, a clamp arranged on the bracket, and a power mechanism, wherein the clamp includes a clamping claw, and the clamping claw includes two clamping plates arranged relatively and capable of relative movement, and the length of the two clamping plates is greater than the distance between the two arms of the silicon rod, so that the clamping claw can clamp the two arms of the silicon rod at the same time. In this device, the clamping plates directly contact the surface of the silicon rod, which easily causes silicon rod contamination. In addition, the mechanical arm can only clamp one group of silicon rods at a time, which has the disadvantage of low efficiency. Utility Model Content
