Description

Technical Field

[0001] The invention belongs to the field of seed crystal pickling, and in particular relates to automatic seed crystal pickling equipment. Background Art

[0002] After the seed crystal is taken out from the rod-pulling machine and polished, it is handed over to the silicon material for cleaning in the form of rough seed crystal. During cleaning, it is necessary to ensure that the corrosion rate of each part of the seed crystal is the same. In the traditional way, personnel wear acid-proof clothing and acid-proof gloves and hold PP rods to constantly turn the seed crystals to ensure a constant corrosion rate. However, this operation method has the following problems: direct manual cleaning in a strong acid environment poses a safety hazard. In order to avoid damage to health, workers need to wear acid-proof equipment when cleaning, which further increases labor intensity; when using tools to shovel the seed crystal, the tool will collide strongly with the seed crystal, causing the seed crystal to be knocked and cracked, posing a quality risk; the pickling liquid has no on-site cooling device, which means that the pickling liquid needs to be removed in time, so an automatic pickling equipment for seed crystals is proposed. Summary of the invention
