Description

Technical Field

When loading, the operator pulls out the loading film box 8, puts the stacked silicon wafers into the loading film box 8, and then pushes the loading film box 8 to the loading position; each loading film box 8 is provided with a group of second lifting units 5 below. After the loading film box 8 is in place, the second lifting unit 5 lifts the loading film box 8 to the suction position of the suction cup 1005, Each time a wafer is taken out, the second lifting unit 5 will lift the silicon wafer appropriately for a certain distance until all the silicon wafers in the loading wafer box 8 are taken out; then the loading wafer box 8 is lowered to the initial position, and the operator puts the silicon wafers in again; the loading wafer box 8 is surrounded by a left wind knife 802 and a right wind knife 804 with compressed air as the air source. Before taking the wafer, the left wind knife 802 and the right wind knife 804 are turned on first, and compressed air is introduced to blow away the stacked silicon wafers and then suck the silicon wafers to prevent the situation of sucking multiple wafers at one time; the wafer taking unit 10 sucks out the silicon wafers in the loading wafer box 8 through the Bernoulli suction cup 1005, and a wafer taking unit 10 is driven by a servo motor 1007 through a reducer 1003 to move the linear module 1001 forward and backward.

When the rear track is idle, it will descend grid by grid to place the cached silicon wafers on the left silicon wafer conveyor line 11. This can also ensure that the unloading basket is full. When replacing, the loading process will not be interrupted; the silicon wafers on the left silicon wafer conveyor line 11 are transferred to the left to the telescopic wafer feeding unit 13, and the telescopic wafer feeding unit 13 finally transfers the silicon wafers on the silicon wafer transmission track to the flower basket 304. The flower basket 304 is fed by the flower basket feeding conveyor line 1 below. After being transferred to the right position, when the flower basket lifting unit 3 rises, the first piece position is flush with the conveyor belt 1312 of the telescopic wafer feeding unit 13, and then the telescopic wafer feeding unit 13 is extended, and the silicon wafer is transferred to the flower basket 304. The flower basket 304 rises grid by grid to transfer the silicon wafer to the flower basket 304. After the flower basket 304 is full, the telescopic wafer feeding unit 13 retracts, and the flower basket 304 rises to a position flush with the flower basket discharge conveyor line 14, and is discharged from the left end of the flower basket discharge conveyor line 14.
