The utility model provides a kind of steel structure building installation positioning device, belong to steel structure building construction technical field.The device structure is ingenious, and it is good to guide, it is convenient to clamp, can be flexibly disassembled, it is convenient for engineering construction use.The electric hoist of the device is fixedly installed on the one side board surface of fixed plate, and a plurality of fixed length's pull cable are fixedly connected on the other side board surface of fixed plate, the free end of each fixed length's pull cable is fixedly bolted screw rod, the drum of electric hoist is wound pull cable, and the free end of pull cable on electric hoist is scattered into multiple strands, and the free end end of each pull cable is fixedly bolted clamping assembly.The device clamps more stable, and the pulling capacity is stronger, and the guiding stability is high, and the alignment accuracy is high, and the assembly construction safety is improved.

The utility model provides a kind of automatic recognition device of degumming and material removal, it is related to silicon wafer production and processing technical field, to solve the existing mechanical arm to execute material removal action, because lack accurate, reliable material removal state identification mechanism, cannot accurately judge whether transfer frame has completely separated from mechanical arm and successfully fallen into degumming pool, this problem can lead to mechanical arm to lift reset, transfer frame is still not correctly separated, and then interfere with the normal progress of subsequent processing process Problem, including main frame;The main frame is rectangular long rod structure.After mechanical arm executes material removal action, before lifting reset, whether transfer frame completely separates from mechanical arm and falls into degumming pool is detected in real time, when identifying that material removal is not successful, can timely feedback to mechanical arm control device, to make mechanical arm execute material removal instruction again, avoid the problem that subsequent processing process is interfered because transfer frame is not correctly separated, the reliability of mechanical arm to execute material removal instruction is significantly improved.
