Detailed Description
The following description will specifically explain embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1 and 2, the wafer taking device of the present invention includes a multi-axis manipulator and a frame 13, the multi-axis manipulator includes two parallel rotating arms, namely a first rotating arm 9 and a second rotating arm 8, one end of the first rotating arm is mounted on the base and is rotatably disposed, the other end is connected with the end of the second rotating arm 8, the other end of the second rotating arm 8 is provided with a turntable 6, and the turntable 6 is provided with a wafer chuck 5 and an infrared sensor 7; the first rotating arm 9, the second rotating arm 8 and the rotating shaft of the rotating platform 6 are arranged in parallel; the multi-axis manipulator is arranged in a lifting mode. The quantity of infrared sensor is two, and is located same height, and infrared sensor scans the wafer of judgement magazine and whether deposited the material in every slot, sets up two infrared sensor and can reduce the erroneous judgement and miss the judgement.
In order to realize the lift of multiaxis manipulator, the utility model discloses a following structure: the multi-axis manipulator structure is characterized in that a lead screw module is arranged in the machine base, a screw rod 4 of the lead screw module is parallel to a rotating shaft of the multi-axis manipulator, a connecting plate 14 is arranged on a nut base 12 of the lead screw module, two sides of the connecting plate 14 are respectively provided with a fixing plate 15, the top of each fixing plate 15 is provided with a top plate 18, the multi-axis manipulator is installed on the top plate 18, a plurality of connecting blocks 17 are further arranged on the fixing plates 15, and the connecting blocks 17 are used for installing and driving. A base plate 11 of a parallel screw rod is arranged on a machine base, two slide rails 3 of the parallel screw rod are arranged on the base plate 11, a cross beam 2 is arranged between two fixing plates, two slide blocks 1 are arranged on the cross beam 2, and the slide blocks correspond to the slide rails one by one.
The screw rotates the reciprocating of nut seat to driving the reciprocating of connecting plate, the connecting plate drives two fixed plates and reciprocates again, and the fixed plate drives roof, connecting block and the crossbeam of being connected with it and removes, and then orders about multiaxis manipulator, motor and slider and reciprocate, and the slider plays direction, supporting role.
