[0024] The beneficial effects of the embodiments of the utility model are as follows:
[0025] The post-inkjet tile detection device of the utility model embodiment is provided with a detection component 2 and a cleaning component 3, the detection component 2 comprises a shell 21, an image collector 22 arranged in the shell 21, and a light-transmitting member 23 located at the bottom of the shell 21 and arranged below the image collector 22, the collection port of the image collector 22 is arranged toward the light-transmitting member 23, the shell 21 and the light-transmitting member 23 can protect the image collector 22, prevent the water vapor and toner generated by the tile from entering the image collector 22, and affect the image collector 2 2, and in order to further improve the accuracy of image acquisition, the cleaning component 3 includes a mobile driving member 31 and a cleaning block 32 connected to the mobile driving member 31, the cleaning block 32 can abut against the bottom surface of the light-transmitting member 23, and the mobile driving member 31 can drive the cleaning block 32 to move along the length direction of the light-transmitting member 23, so that the light-transmitting member 23 can be cleaned to prevent water vapor and toner from adhering to the light-transmitting member 23, thereby further ensuring the accuracy of image acquisition and ensuring subsequent production.
[0026] In the embodiment of the utility model, the image collector 22 is a CIS camera, which is a contact image sensor (Contact Image Sensor) camera, which has the characteristics of small size and high integration, is simpler than traditional CCD / CMOS cameras, and has relatively low requirements for installation space and component matching. Since the CIS camera is based on photosensitive semiconductor devices, it can accurately capture pattern defects such as white edges, white spots, black spots, double flowers, and green spots on the surface of ceramic tiles after inkjet printing, so that ceramic tiles can be detected and screened. CIS cameras are usually long strips and can directly cover the width of ceramic tiles. During the operation of ceramic tiles, a single image collector 22 can complete the image acquisition of a single ceramic tile.
[0027] Specifically, see Figure 2 The cleaning assembly 3 also includes a pulley 33 drivingly connected to the movable end of the mobile driving member 31, a synchronous belt 34 wound around the pulley 33, and a support frame 35 fixed on the synchronous belt 34. The mobile driving member 31 is preferably a rotating motor, which can drive the pulley 33 to rotate, the pulley 33 drives the synchronous belt 34 to move, and the synchronous belt 34 drives the support frame 35 to move. A fixing groove 351 is provided on the support frame 35, and the cleaning block 32 is detachably fixed in the fixing groove 351. Therefore, the mobile driving member 31 can drive the cleaning block 32 to move at the bottom of the light-transmitting member 23 to clean the light-transmitting member 23. After a period of use, the cleaning block 32 can be replaced to ensure cleaning efficiency.
[0028] The image collector 22 is in the shape of an elongated strip and can be arranged along the length direction of the fixing frame 12. The length direction of the synchronous belt 34 is parallel to the length direction of the light-transmitting member 23, so as to drive the cleaning block 32 to move in the length direction of the light-transmitting member 23. The length direction of the light-transmitting member 23 is parallel to the length direction of the image collector 22, and the light-transmitting member 23 can form a good coverage for the image collector 22.

When the mobile driving member 31 drives the support frame 35 to move, the guide rail 36 limits the moving trajectory of the support frame 35 through the slider 37, thereby limiting the movement of the cleaning block 32.
[0030] See also Figure 3The detection component 2 further includes a lifting drive 24, a lifting screw 25 and a lifting plate 26. The lifting screw 25 is vertically arranged. The movable end of the lifting drive 24 is connected to the lifting screw 25. The bottom of the lifting screw 25 is connected to the lifting plate 26.

The detection component 2 also includes a travel switch 27. The travel switch 27 is located on the side of the lifting screw 25. When the image collector 22 is lifted or moved, the travel switch 27 can detect the image collector 22, so as to detect and control the lifting stroke of the image collector 22.
[0031] In order to be able to capture images of tiles, a baffle 13 is also provided at the bottom of the fixing frame 12. A perforation 131 is provided in the baffle 13. The shape of the perforation 131 corresponds to the projection shape of the image collector 22 on the horizontal plane. The acquisition port of the image collector 22 faces the perforation 131. Through the perforation 131, the image collector 22 can capture images of the tiles below the baffle 13. At the same time, the lifting drive 24 can drive the image collector 22 to pass through the perforation 131 to move below the baffle 13 to adjust the focal length and image acquisition range. An air inlet plate 14 is provided below the baffle 13. One side of the air inlet plate 14 is fixed to the lower surface of the baffle 13, and the other side extends downwardly in an inclined direction toward the perforation 131. An air inlet channel 15 is formed between the air inlet plate 14 and the baffle 13, and the heat and water vapor emitted by the tiles can enter the air inlet channel 15.
[0032] See also Figure 4 After the inkjet is completed, the temperature of the tile is relatively high. The water vapor and toner attached to the surface of the tile will drift upward with the heat. In order to prevent the water vapor and toner from affecting the light-transmitting member 23 and the image collector 22, the post-inkjet tile detection device also includes an exhaust component 4, which includes a slot tube 41 fixed to the upper surface of the baffle 13 and located at the side of the perforation 131, and an air duct 42 fixed to the top of the slot tube 41. One end of the air duct 42 is connected to an external exhaust device, and the other end is connected to the slot tube 41. The bottom of the slot tube 41 is provided with an air inlet slit 411, and the air inlet slit 411 is connected to the air inlet channel 15. During operation, water vapor and toner will enter the air inlet channel 15, then enter the slot tube 41 through the air inlet slit 411, and be discharged from the air duct 42 under the action of the external exhaust device, thereby further ensuring the cleanliness of the surface of the light-transmitting member 23 and the normal operation of the image collector 22.
[0033] The detection assembly 2 further includes a heat sink 28 , which is fixed to the top of the image collector 22 and is used to dissipate heat from the image collector 22 , thereby further ensuring the normal operation of the image collector 22 .
