[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0020] like Figures 1 to 4 As shown in this embodiment, a novel four-station OBB testing mechanism includes a conveyor rail 1 and a turntable 2. A voice coil motor 3 is installed at the rear end of the conveyor rail 1. A lifting frame 4 is vertically connected to the drive end of the voice coil motor 3.

Several upper suction nozzles 8 are installed at the lower end of the adsorption components 7. A turntable air pipe connector 9 is installed in the middle of the turntable 2. The turntable air pipe connector 9 communicates with the upper suction nozzles 8 after passing through the interior of the turntable 2 and the interior of the adsorption components 7.
[0021] The conveyor rail 1 moves the silicon wafer backward. When it reaches the last end, the voice coil motor 3 controls the lifting frame 4 to rise. The two sides of the lifting frame 4 pick up the silicon wafer from the two sides of the conveyor rail 1 through the lower suction nozzle 5 and move it upward until it reaches the station 6 position of the turntable 2. At this time, the suction component 7 of the turntable 2 controls the upper suction nozzle 8 to pick up the silicon wafer, the lower suction nozzle 5 releases the silicon wafer, and then the turntable 2 rotates to transfer the picked-up silicon wafer to the IV detection section for testing.
[0022] A conveyor motor 10 is installed at one end of the conveyor guide rail 1. The drive end of the conveyor motor 10 is connected to a conveyor synchronous pulley 11.

[0023] The conveyor motor 10 provides power. Under the transmission of the conveyor synchronous pulley 11 and the conveyor synchronous belt 12, the drive shaft 14 rotates, and the conveyor wheel 13 rotates in turn under the action of the drive shaft 14. The conveyor belt 15 can then convey the silicon wafer backward. During the conveying process, the presence of the silicon wafer is sensed by the conveyor sensor.
[0024] The lower part of the conveying guide rail 1 is provided with a centering and correcting motor 16, the driving end of the centering and correcting motor 16 is connected with a centering and correcting synchronous wheel 17, the centering and correcting synchronous wheel 17 is transmissionally connected with a centering and correcting synchronous belt, the centering and correcting synchronous belt is fixed with a centering and correcting support 19, a pair of centering and correcting supports 19 are located at the two sides of the conveying guide rail 1, and the centering and correcting support 19 is provided with a centering and correcting guide wheel 20.
[0025] When the silicon wafer moves to the rear of the conveying guide rail 1, the centering and correcting motor 16 drives the centering and correcting support 19 to move from the two sides to the middle along the conveying slide rail 18 through the centering and correcting synchronous wheel and the centering and correcting synchronous belt, so as to align the silicon wafer, wherein the centering and correcting guide wheel 20 reduces the friction.
[0026] The side of the rotating disc 2 is provided with an air channel groove, the outer end of the adsorption assembly 7 is connected to the air channel groove, the air channel groove is covered with a sealing plate 21, and the rotating disc air pipe joint 9 is located at the end of the air channel groove far from the adsorption assembly 7.
