Operating procedure:
The size of the ceramic tile detected first according to the needs of input, by background server control locating detent D21, locating detent B29 and locating detent C24 movements, make grow and be wider than the ceramic tile dimension that needs detect the 5% of its rectangular extent limited;
Background server is powered to the electromagnet 37 on locating detent A10 and locating detent B29, and cornerite 33 moves down, and exposes support Plate 34;
In setting pressure sensor 50 in support plate 34, pressure sensor 50 is to background server real-time Transmission number pressure According to;Background server controls feed conveyor belt 8 to transmit ceramic tile to alignment system, while controls and coordinate conveyer belt 9 to be transmitted with charging Band 8 is run in the same direction, to receive ceramic tile;Ceramic tile is fallen into alignment system until the received locating detent C24 of background server and positioning The signal that the pressure sensor 50 of pawl D21 is fed back;Background server controls locating detent A10 and locating detent B29 playback, and makes straight line Motor driving locating detent B29, locating detent C24 and locating detent D21 movements, to reduce rectangular extent, untill ceramic tile is clamped;
Background server lights the lamp bar positioned at initial position, starts at the dog-ear of the cornerite 33 of locating detent A10 for origin It is scanned;
Linear motor drives each 0.5 millimeter of the stepping of lamp bar, is reflected through ceramic tile and is irradiated in the light of light receiver system 3 Follow stepping;
The laser lamp unit of linear motor lamp bar uses identical light source 2, and the optical filtering on each row's laser pickoff 48 The wavelength of the permeable light of mirror 22 differs;
Background server can will receive laser by the laser pickoff 48 of feedback signal according to capable classification is discharged into first The most row of number is as base platoon, if the laser pickoff 48 in base platoon has the laser pickoff of not feedback signal 48, and not the laser pickoff 48 of feedback signal be less than continuous 10 when, background server passes through display screen character prompt, sound Or luminous form alarm;
Before alarm, servomotor 15 drives turntable 17 to rotate 180 degree, by lamp bar in an identical manner again to ceramic tile It is scanned;
After the completion of scanning, the cornerite 33 of background server control clamping jaw A and clamping jaw B is fallen;
For the product of alarm, the solenoid valve of background server control cylinder 18 is opened, and 18 inflated elongation of cylinder, will position Plate one end starts, while controls and coordinate conveyer belt 9 to invert, and product is discharged into recovery system;
For the product do not alarmed, background server control coordinates conveyer belt 9 to invert, and ceramic tile is connect and guides to follow-up connecing and draws Conveyer belt 5.
The gentle sorting technique of the inspection, recovery system include arc track 6 and recycling conveyer belt 4, the top of arc track 6 Portion is located at below positioning plate, and 6 bottom of arc track is tangentially connected with recycling conveyer belt 4, and the ceramic tile laid down passes through arc track 6 Recycling can be slipped to it is transmitted to and is connect carrying-off.
Operation principle:
The gentle sorting technique of the inspection, it is flat to carry out inspection using reflection of the ceramic tile to light;It is unlimited to be incorporated into the laser penetrated Wavelength, only by each laser pickoff 48 install optical filtering 22, allow the light source 2 of fixed wave length by that is, Only detect the light of this kind of wavelength.By the difference of the light transmitting wavelength of each optical filtering 22, to distinguish each light irradiation in lamp bar Incident beam, the specific foothold of each luminous point is judged with this, and it is smooth with the continuous path of multiple spot to obtain ceramic tile surface The situation of degree;Lamp bar is often irradiated once, according to the situation of stopping over of luminous point, selects baseline.After there is trachoma, light is irradiated to In trachoma, due to trachoma out-of-flatness, angle of reflection can change, and can not be irradiated on baseline, that is, on baseline luminous point lack Lose, due to the laser lamp in lamp bar spread length and often arrange laser pickoff 48 interval and starting point all be correspond , as long as so there is laser pickoff 48 not receive light on baseline, then judge that corresponding light has been got in trachoma, due to In lamp bar the center spacing of lamp be 0.5 millimeter, so more than ten laser pickoffs 48 do not receive laser situation be more than The pitting of 5mm, beyond the scope of trachoma, to avoid storage and computing increase, excludes, only detects no more than ten laser Receiver 48 does not receive the situation of laser.It is accurately detected out trachoma.
If there is this situation, positioning plate can start, and conveyer belt 9 provides power with, and ceramic tile is imported arc track 6, as failure product horizontal linking is transmitted to by coordinating conveyer belt 9 to provide power, by ceramic tile by centralized collection, other situations On discharge belt.
The application detects ceramic tile twice at the same time, and is carried out respectively from the both sides of ceramic tile to inspection, being detected when twice Trachoma position overlap, be just determined as trachoma, and ceramic tile is disposed by arc track 6.
