Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1 and 2, a kind of monocrystalline silicon piece outer edge automatic chamfering device, it includes casing 1, and the casing 1 is in square
Shape is provided with positioning plate 2, microswitch 3 and cylinder 4 in the casing 1, and the positioning plate 2 is set to the back plate of casing 1
On, microswitch 3 is set on the left plate of casing 1, and straight slot is offered on left plate, grinding wheel 5, sand are rotatably installed in straight slot
Wheel 5 is located at the front side of microswitch 3, and the foreboard that cylinder 4 runs through casing 1 from front to back is arranged, is provided on the piston rod of cylinder 4
Connecting plate 6, connecting plate 6 and the piston rod of cylinder 4 are arranged in angle, and the bottom of connecting plate 6 is rotatably installed with main belt through shaft
Wheel 7 and driven pulley 8, are equipped with belt 9, the top of connecting plate 6 is installed with electricity between driving pulley 7 and driven pulley 8
The output shaft of machine 10, motor 10 is connect with the shaft of driving pulley 7, vacuum cup 11 is provided in the shaft of driven pulley 8, very
Suction disk 11 is located at 6 top of connecting plate, and vacuum cup 11 and the shaft of driven pulley 8 are coaxially disposed, the center of vacuum cup 11
Distance away from positioning plate 2 is equal to the distance of the centre-to-centre spacing microswitch 3 of vacuum cup 11；The facing attachment further include controller and
Vacuum extractor, vacuum extractor are connect with vacuum cup 11, the controller and vacuum extractor, motor 10, microswitch 3
It is connected with cylinder 4.
The course of work of the utility model is as follows：Grinding wheel 5 is first set to do high speed rotary motion, then the monocrystalline silicon piece that will wait for chamfering
12 lie against 11 top of vacuum cup, and monocrystalline silicon piece 12, which is then leaned against positioning plate 2, realizes Primary Location, finally by monocrystalline silicon piece
12 lean against on microswitch 3, and microswitch 3 sends out electric signal to controller at this time after being depressed, and controller controls vacuum means
Startup is set, vacuum extractor vacuumizes vacuum cup 11, and monocrystalline silicon piece 12 is sucked vacuum cup 11, realizes monocrystalline silicon piece
