Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in more detail.
Referring to accompanying drawing 1, the utility model is installed left erection column 1 and right erection column 11 in the place ahead of film magazine 3, and left erection column 1 and right erection column 11 are fixing with fixed head 9, and fixed head 9 is placed on the base 10.Distance is greater than the size of wafer 7 between left side erection column 1 and the right erection column 11.
Referring to accompanying drawing 2, left side erection column 1 and one group of light source reflector 5 and light source receiver 2 are housed respectively above the right erection column 11, light source reflector 5 is made up of light source transmitting terminal 12, tutorial light 13 and holding wire 14, the concrete quantity of light source reflector 5 is decided on the quantity of film trap in the film magazine 3, be generally 13-25, light beam 4 can be blocked by wafer 7, but can not be blocked by film magazine 3.Light source receiver 2 is identical with the structure of light source reflector 5.
Light source reflector 5 produces light signal by power supply, passes to light source receiver 2 then, and light source receiver 2 is converted into the signal of telecommunication with light signal, by the amplifying circuit amplification voltage signal, is obtained relevant information by data acquisition unit again.By position and the quantity of obtaining wafer 7 in the film magazine 3 in real time, manipulator can remove to grasp and discharge wafer 7 rapidly.
Referring to accompanying drawing 3, left erection column 1 described in the utility model and right erection column 11 have position adjusting mechanism 6, and it is made of adjustment pad 15, adjustment bullet pad 16, adjustment nut 17, adjustment double-screw bolt 18.Can adjust the upper-lower position of left and right erection column by adjusting position adjusting mechanism 6 to adapt to the position of wafer 7 in the film magazine 3, the equipment of preventing flase drop occurs and surveys.
Referring to accompanying drawing 4, slide plate detector 8 described in the utility model is installed in the dead ahead of film magazine 3, exceeds film magazine 3 distances and is the 5-20 millimeter, it is made up of a reflective photoelectric sensor, whether in film magazine 3 have wafer 7 skid off, be used for reminding the user if can be used to detect, increase the security reliability of equipment.
The utility model has been realized the real-time detection of wafer 7 in the film magazine 3, and the information that obtains is passed to control unit, is grasped rapidly by control unit control manipulator or discharges wafer, reduces operate time, enhances productivity.
The course of work of the present utility model is as follows:
Behind the opening of device, light source reflector 5 sends light beam 4 because applying power supply.
If do not have to install the film magazine 3 that has wafer 7 at fixed head 9, then light source receiver 2 receives by light source reflector 5 and sends light beam 4 back generation photoelectric currents, received effective voltage signal by current-to-voltage converting circuit, voltage amplifier circuit by data acquisition unit again, then these signals are passed to control unit, control unit just can be made the information that does not have wafer 7 in the film magazine 3.
If at fixed head 9 film magazine 3 that has wafer 7 is installed, then wafer 7 will block the light beam 4 that light source reflector 5 sends, light source receiver 2 does not receive light signal just can not produce the signal of telecommunication, data acquisition unit does not just receive voltage signal yet, and control unit just can be made the information that wafer 7 is arranged in the film magazine 3.
Wherein, each wafer 7 is corresponding the placement in the film trap all, and the corresponding a pair of light source reflector 5 of each film trap and light source receiver 2, therefore, control unit will be according to each useful signal to light source reflector 5 and light source receiver 2, determine whether each film trap has wafer 7, remove to control manipulator according to the information that obtains then, whether arrive corresponding film trap extracting or discharge wafer 7.
If film trap has deviation in the position of light source reflector 5 and light source receiver 2 and the film magazine 3, can adjust the position of left erection column 1 and right erection column 11 by position adjusting mechanism 6, light beam 4 can be blocked by the wafer 7 in the film magazine 3, realize the real-time detection of wafer 7 in the film magazine 3.
Wherein, being installed in the slide plate detector 8 in film magazine 3 dead aheads, whether in film magazine 3 have wafer 7 skid off, be used for reminding the user if can be used to detect, and increases the security reliability of equipment.
Adopt the utility model can effectively reduce the operate time of manipulator, enhance productivity.
