As preferably, described air knife is the column that lower end closed upper end offers ventilation hole, be provided with multiple small air knife mouth column air knife is vertically uniform towards the side of silicon chip, ventilation hole is connected with air knife mouth, and the height that air knife mouth is arranged stacks height a little more than photovoltaic silicon wafer.
As preferably, described baffle plate is by backboard and side shield) form, the height of backboard and side shield exceedes photovoltaic silicon wafer and stacks height, and backboard and side shield are plastics rigid plastic sheet, are stained with elasticity soft silica gel layer at rigid plastic sheet towards silicon chip side.
As preferably, described air supply plant comprises steel pipe, brachytracheae, threeway, tube connector, long air pipe and adjuster valve, fastener for connection air knife and brachytracheae, brachytracheae, tube connector and long air pipe link together and are interconnected by threeway, regulate the adjuster valve of input air-flow to be connected on long air pipe.
As preferably, the plastic flexible pipe of described brachytracheae, tube connector, long air pipe to be all external diameters be 8mm.
As preferably, described weight tray is polypropylene board, and on polypropylene board, pad is provided with corrugated sheet resilient coating.
Beneficial effect: the quantity reducing silicon wafer bearing box, has saved the cost of Carrier box, reduces human users's difficulty, increases work efficiency, and reduces manpower demand and cost.
