[0023] Please refer specifically to Figure 1 , a conveyor belt that cooperates with the printed product 2 is installed at the bottom of the detection workbench 8. By setting the above structure, the present invention is to achieve automatic blanking.
[0024] Working principle: During use, the printed product 2 in the loading machine 1 is automatically fed into the vacuum screen printing table 3. Then, the first CCD camera 4 takes pictures of the printed product 2, and the second CCD camera 13 takes pictures of the screen plate 12. After processing, the second actuator 304 in the vacuum screen printing table 3 is started. In cooperation with the second rack 305, the conveying platform 309 is moved and adjusted along the direction of the second linear guide 307. Using the position data obtained by taking pictures of the screen plate 12 with the second CCD camera 13, the printing position of the printed product 2 is automatically overlapped with the printing position of the screen plate 12. Then, the first actuator 302 is controlled to start. In cooperation with the first rack 303, the vacuum screen printing table 3 and the printed product 2 enter directly below the screen plate 12 along the direction of the first linear guide 301. Then, the first actuator 302 is stopped, and then screen printing is performed. During the printing process, the drive motor 702 is started to drive the second screw 703 to rotate, so that the mounting slide plate 701 moves downward along the direction of the slide rail 704. Then, the printing machine 705 is used for work. After printing, the conveying platform 309 arranged below the vacuum screen printing table 3 rises under the action of the pusher 306 and sends the printed product 2 into the inspection workbench 8. At the same time, the second CCD camera 13 moves above the inspection workbench 8 under the action of the second guiding member 6. During this process, the second guiding slide plate 601 can adjust its position on the third linear guide 10, and the second guiding motor 602 can also be started to drive the first screw 603 to rotate. In cooperation with the screw sleeve 604, the mounting frame 9 and the second CCD camera 13 move along the direction of the second guiding slide plate 601. Then, the second CCD camera 13 takes pictures of the printed product after printing to perform screen printing quality inspection. When the printing quality of the printed product 2 is qualified, the inspection workbench 8 sends the printed product into the baking line, thus realizing automatic unloading. When the printing quality of the printed product is unqualified, the equipment stops running, and the operator checks whether there is a problem with the screen plate.
