The utility model discloses a theory of operation:
the working principle of the carrying platform 5 is as follows: the product to be printed is conveyed to the feeding and discharging runner 56 at one end, and at the moment, the first horizontal carrying table surface 52 is lifted under the action of the lifting mechanism 55 to support the product; then the contraposition camera 61 and the fifth camera 62 are triggered to take a picture, and after the picture taking is finished, the horizontal carrying table 52 carries the product to the lower part of the screen 4 under the action of the linear motor for printing; after printing is finished, the horizontal carrying table 52 carries the product to the feeding and discharging runner 56 at the other end, the horizontal carrying table 52 descends, the product is placed on the feeding and discharging runner 56 at the other end, and one round of carrying is finished; since the second horizontal carrying table 52 also performs the above process, the second horizontal carrying table 52 is in a raised state when the first horizontal carrying table 52 completes one round of carrying, and the first horizontal carrying table 52 is in a lowered state, so that the second horizontal carrying table 52 can pass under the second horizontal carrying table 52 to return to the position under the original loading and unloading runner 56 to start a new round of carrying; it is achieved that two horizontal transfer levels 52 can be simultaneously transferred on one transfer platform 5.
The operating principle of the alignment mechanism 1 is as follows: the output shafts of the X1 alignment mechanism motor 12, the X2 alignment mechanism motor 13 and the Y alignment mechanism motor 14 rotate to drive the screw rod 16 to rotate, and then the screw rod 16 drives the translation mechanism 17 to move along the axial direction of the screw rod 16 integrally. The moving direction of the slide block 19 in the translation mechanism 17 is vertical to the axial direction of the corresponding screw rod 16; therefore, when the translation mechanisms 17 corresponding to the motors 12 and 13 of the X1 alignment mechanism and the X2 alignment mechanism move along the X axis integrally, the slide block seat 20 in the translation mechanism 17 corresponding to the motor 14 of the Y alignment mechanism also moves along the X axis; when the translation mechanism 17 corresponding to the Y alignment mechanism motor 14 integrally moves along the Y axis, the slider seat 20 in the translation mechanism 17 corresponding to the X1 alignment mechanism motor 12 and the X2 alignment mechanism motor 13 also moves along the X axis; and because the translation mechanism 17 is fixedly connected with the screen fixing frame 18, the X1 alignment mechanism motor 12, the X2 alignment mechanism motor 13 and the Y alignment mechanism motor 14 are matched with each other, so that the screen fixing frame 18 can translate or deflect on an X-axis plane and a Y-axis plane. Specifically, when the X1 alignment mechanism motor 12 and the X2 alignment mechanism motor 13 move in the same direction, the translation mechanism 17 drives the screen fixing frame 18, and the screen fixing frame 18 drives the screen plate 4 to perform translation adjustment in the X-axis direction; when the X1 contraposition mechanism motor 12 and the X2 contraposition mechanism motor 13 move reversely, the translation mechanism 17 drives the screen fixing frame 18, the screen fixing frame 18 drives the screen plate 4 to perform theta angle adjustment, and the theta angle is a deflection angle of the screen plate 4 and an X-Y axis coordinate system; when the Y alignment mechanism motor 14 moves, the translation mechanism 17 drives the screen fixing frame 18, and the screen fixing frame 18 drives the screen plate 4 to perform translation adjustment in the Y axis direction.
The working principle of the vision alignment printing mechanism 8 is as follows: firstly, a product to be printed is placed on the feeding and discharging flow channel 56, the controller firstly utilizes the fifth camera 62 to detect the appearance of the product, then utilizes the four alignment cameras 61 to obtain the position information of the product, and utilizes the two screen positioning cameras 7 to obtain the position information of the screen 4 as a reference position, and then controls the alignment mechanism 1 to adjust the offset positions of the screen 4 on the X axis, the Y axis and the theta axis according to the offset value between the two position information, then the horizontal carrying table 52 carries the product to the lower part of the screen 4, and then the controller controls the scraper ink return knife lifting mechanism 3 to descend, and the scraper 36 moves horizontally under the action of the scraper horizontal movement straight line module 2 to perform printing work.
