Background

According to the method, screen printing is a printing mode different from flat plate, bald plate and gravure printing. The screen printing process is that ink is added to a screen with fine holes, the ink is extruded by a scraper to pass through a printing plate, the ink passes through the printing plate to paper placed under the printing plate, and the parts which do not need to be printed are manually or mechanically made into negative wax plates on the screen for protection. Flat, convex, and gravure circular cylinder plates limit the ability to print only thin films or sheet materials such as paper, paperboard, plastic films, metal sheets, and the like. The screen printing is not limited by the material, and the material to be printed is plastic, metal, fabric, glass, ceramic, leather, etc., and can be screen printed regardless of the thickness, the plane, the curved surface, etc. Thus, screen printing is a technique quite common in high-tech industries or manufacturing.

the task content is determined to be a single product or a plurality of products. An operator analyzes the printing process required by each product in advance, and sets the task as a single product or a plurality of products according to the number of printing stations and the requirement of the operator. For example, suppose that the product a requires 3 printing processes, the product B requires 2 printing processes, and the number of printing stations of the system is 5, so that the task can be set to simultaneously execute the printing operation of the product a and the product B, wherein 3 printing stations are responsible for printing the product a, and the remaining 2 printing stations are responsible for printing the product B, which is the printing task of the plurality of products; or only the printing operation of the B product is executed, at the moment, 2 printing stations can be allocated to execute the first printing process of the B product, 2 printing stations execute the second printing process of the B product, and the rest 1 printing station provides temporary support, namely the printing task of the single product.

And setting the digital device and the printing station corresponding to the printing process according to the task content. After confirming the single product or the plurality of products and the printing process, the operator can set parameters of a plurality of mechanisms in the system disclosed in the above embodiment by a digital device, such as readers, pneumatic elements and electric elements configured by the mechanisms such as the conveying mechanism, the transfer mechanism, the printer and the oven, and the moving speed of the conveying mechanism and the heating temperature of the oven; and presetting which printing process each printing station of the printing area should perform in the printing process.

The first conveying mechanism moves the carrying disc to the front of the printing station of the first printing process, at the moment, the digital device automatically judges that the carrying disc should enter the printing station after reading the position and the working progress of the carrying disc through the reader of the printing area, then a printing station blocking device of a printing station transfer conveying mechanism is controlled to ascend to stop the carrying disc moving forwards, and then two printing station lifting devices of the printing station transfer conveying mechanism drive a printing station roller set to ascend to enable the carrying disc to be moved into the printing station by the printing station roller set; when the carrying disc enters the printing station, one roller set of the printing station will continuously move the carrying disc until it touches one blocking strip and stops moving, at this time, the two positioning devices of the printing station are controlled by the digital device to move and push against the two notches of the carrying disc to complete the fixation, and then one printing device of the printing station starts the printing operation.

And returning the printing ink to the first conveying mechanism after printing according to the task content. After the printing station finishes printing operation, the two positioning devices are controlled by the digital device to be separated from the carrying disc, the roller set of the printing station starts to rotate reversely to convey the carrying disc to leave the printing station and move to the roller set of the printing station of the transfer conveying mechanism of the printing station, and then the roller set of the printing station of the transfer conveying mechanism of the printing station is driven by the lifting devices of the two printing stations to descend, so that the carrying disc returns to the first conveying mechanism and continues to move along the first conveying mechanism.

And transferring the task content to a second conveying mechanism and drying the task content in an oven. When the loading tray moves to a return area, the digital device controls a first return blocking device of a first return transfer conveying mechanism to ascend to stop the loading tray from advancing, and then two first and second return roller sets of the first return transfer conveying mechanism and a second return transfer conveying mechanism are driven by a plurality of first and second return elevating devices to ascend so that the first return transfer conveying mechanism conveys the loading tray away from the first conveying mechanism, and the second return transfer conveying mechanism receives and moves the loading tray to the second conveying mechanism; after the carrying tray touches a blocking block on the second conveying mechanism, the carrying tray stops moving, and then the lifting devices are controlled by the digital device to drive the first and second roller sets to descend, so that the carrying tray returns to the second conveying mechanism and moves into an oven of the oven area along the second conveying mechanism to perform drying operation.

And judging the current printing progress in a finished product/semi-finished product transfer conveying area according to the task content. After the carrier tray is dried, the carrier tray is moved into a finished product/semi-finished product transfer area, and the digital device reads the radio frequency tag of the carrier tray through the reader of the finished product/semi-finished product transfer area to confirm the current working progress and position; after automatically judging that unfinished printing processes still exist, the digital device controls a second blocking device of a second semi-finished product transfer conveying mechanism to ascend so as to stop the carrying disc to advance, then a plurality of first and second semi-finished product lifting devices of the two semi-finished product transfer conveying mechanisms drive two first and second semi-finished product roller sets to ascend, the first semi-finished product roller set conveys the carrying disc to leave the second conveying mechanism, and the second semi-finished product roller set bears and moves the carrying disc to the first conveying mechanism; when the carrier plate touches a stop block of the first conveying mechanism, the carrier plate stops moving, and then the first and second semi-finished product lifting devices of the first and second semi-finished product transferring and conveying mechanisms drive the first and second semi-finished product roller sets to descend, so that the carrier plate returns to the first conveying mechanism to perform a second or next printing process.
