Embodiment
The utility model utilizes refraction principle and the photosignal change principle of light, and a kind of novel glass substrate crushing pick-up unit is provided.
According to the refraction principle of light, light is injected the another kind of medium from a kind of medium, can produce refraction.Incident angle, refraction angle are respectively incident ray, refracted ray and normal, and (normal is the vertical line of two medium contact faces; If two medium contacts point then is the vertical line of contact point tangent line) angle.If the Media density of injecting is greater than script light place Media density, then the refraction angle is less than incident angle.Otherwise then the refraction angle is greater than incident angle.
Light enters medium (glass substrate) perpendicular to medium, and namely incident angle is 0 °, and then the refraction angle is 0 °.As shown in Figure 2, vertically enter glass substrate from air from light source emitter light out, vertically enter the air from glass substrate, it is constant that radiation direction remains.
When light when non-perpendicular direction enters glass substrate from air, reflect in glass substrate that (Media density of glass substrate is greater than air, then the refraction angle is less than incident angle) after, enter the air from glass substrate and again to reflect (Media density of air is greater than glass substrate, and then the refraction angle is greater than incident angle).As shown in Figure 3, airborne incident ray is no longer perpendicular to glass substrate, and incident angle is ∠ 1, and the refraction angle is ∠ 2, and ∠ 1 is greater than ∠ 2; Refracted ray then in this uniform dielectric of glass substrate along rectilinear propagation, when arriving glass substrate edge again, enter the air from glass substrate and again to reflect, incident angle is ∠ 3, the refraction angle is ∠ 4, ∠ 4 is greater than ∠ 3.
Therefore as shown in Figure 4 and Figure 5, when fragmentation occurs glass substrate, if light source emitter light is out injected from breakage, then reflect the rear to significantly skew occurs through glass substrate.During glass substrate generation crackle, the cracks refraction rear of light source emitter light out in glass substrate is to also obvious skew occuring.
As shown in Figure 6, the glass substrate detection system that the utility model provides based on the light refraction principle, light signal transmitter unit 601 and light signal receiving element 602 can be set respectively in the transport tape both sides of glass substrate, the light that light signal transmitter unit 601 is launched can be injected in the glass substrate along being parallel to glass substrate surface level direction from the side of glass substrate, and when not having glass substrate on the transport tape, the light signal that light signal receiving element 602 can receiving optical signals transmitter unit 601 be directly launched.Like this, when glass substrate was intact, light signal penetrated along incident direction after glass is basic, can be received by light signal receiving element 602, when glass substrate had breakage, light signal was offset after the glass substrate refraction, and light signal receiving element 602 does not receive refract light.
Concrete scheme is as follows, and the glass substrate detection system that the utility model provides mainly comprises:
Light signal transmitter unit 601 is positioned at glass substrate transport tape one side, be used for to send from the glass substrate side along being parallel to glass substrate surface level direction and injects light signal in the glass substrate;
Light signal receiving element 602 is positioned at the directly position of the light signal of receiving optical signals transmitter unit 601 emissions of glass substrate transport tape opposite side;
Photosignal converting unit 603 connects the light signal receiving element, is used for changing the light signal that the light signal receiving element receives into electric signal and output;
The application said system as seen, when glass substrate transmits along transport tape, because light signal receiving element 602, be positioned at the directly position of the light signal of receiving optical signals transmitter unit 601 emissions of glass substrate transport tape opposite side, send light signal if therefore start light signal transmitter unit 601, after light signal is injected glass substrate one side and is penetrated from opposite side, should be received by light signal receiving element 602, in case glass substrate generation breakage or crackle cause the light refraction direction to be offset, then light signal receiving element 602 can't receive light signal again.
That is to say, when control module 604 does not receive the electric signal of photosignal converting unit 603 outputs, just can judge that breakage may occur in glass substrate current detection position, trigger accordingly Alarm Unit 605 alarms, the staff can stop the transmission glass substrate according to alarm signal and further process.
For further automatically controlling testing process, open detection when needed, close when not required detection, the position detection unit 606 of glass substrate can be set at transport tape, position detection unit 606 is positioned on the glass substrate transport tape and connection control unit, send enabling signal to control module when detecting glass substrate front end on the transport tape and arriving the position that the light signal with 601 emissions of light signal transmitter unit intersects, and the glass substrate rear end sends shutdown signal 2 to control module when leaving this intersection location.Like this, open light signal transmitter unit 601 when control module 604 receives enabling signal, when enabling signal disappears, close the light signal transmitter unit, and send alerting signal when during the light signal transmitter unit is opened, not receiving electric signal.Like this, when not having the glass substrate transmission, whole system is in semi-closed state.
Further, still referring to shown in Figure 6, can also be when detecting glass substrate breakage, automatically the control transport tape is out of service, for example: the propulsion system 607 of glass substrate transport tape are connected to control module 604, control module 604, when sending alerting signal, control propulsion system 607 are out of service.
In the better scheme, light signal transmitting element 601 is the laser signal transmitting element, and light signal receiving element 602 is the laser signal receiving element.
The detection system of the glass substrate that the utility model provides utilizes optical principle can accurately detect the different broken shape of glass substrate, effectively avoids the broken glass substrate that the equipment injury is reached lower operation is impacted.This device can be widely used in array, one-tenth box and the color membrane production equipment etc. of glass substrate production and TFT-LCD technique.
Further, the utility model is logical can be in the situation that detect the transmission that glass substrates crash in time stops glass substrate, accurately detecting glass substrate whether on the broken basis, further after glass substrate generation fragmentation, in time the equipment of stopping checks, avoids glass substrate to continue to occur broken situation; After checking glass substrates crash, can also avoid the broken glass substrate to flow to next operation, affect the production of next operation, and avoid the broken glass substrate to the equipment injury, prevent larger loss.
Obviously, those skilled in the art can carry out various changes and modification to the utility model embodiment and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
