9. The screen printing method of the automatic plastic cover UV screen printing device based on the claim 1 is characterized by comprising the following specific steps of:
(1) firstly, after the outer cover is formed, the corresponding paint spraying treatment is carried out, then the cover body structure is assembled with other components of the cover body, and the cover body structure is packed after the assembly;
(2) pouring the cover body packaged in the step (1) into a material box of a feeding station, continuously lifting the cover body in the material box by a lifting circulating conveyor belt and placing the cover body in a vibration disc, vibrating the cover body by the vibration of the vibration disc to enable the cover body to perform irregular motion under the action of vibration, and due to the structure of an inclined surface of the bottom end surface of the vibration disc, when the side wall surface of the bottle cap faces the bottom end surface of the vibration disc due to vibration, rolling occurs, discharging is performed from a discharge port, horizontal gathering conveying is performed by the feeding circulating conveyor belt, continuous discharging and gathering occur due to continuous vibration, so that a large number of bottle caps are horizontal;
(3) the bottle caps are gathered through the feeding circulating conveying belt after being discharged horizontally, although the bottle caps can be guaranteed to be arranged horizontally, the opening direction of the bottle caps cannot be determined, the opening direction of the bottle caps can be checked through the cap kicking assembly, the specific process is that after the bottle caps are gathered on the feeding circulating conveying belt, the opening direction of the bottle caps is checked through the laser range finders at the discharging ends of the bottle caps, the bottle caps are in sleeved fit with the fixed shafts on the silk-screen station, the openings of the bottle caps need to face the fixed shafts, if the corresponding opening direction of the bottle caps detected by the laser range finders is wrong, the bottle caps can be pushed into the material receiving box through the push plate, and therefore the condition that the opening direction of all the bottle caps entering the blanking table with silk screen is correct is met;
(4) the bottle lid enters into blanking bench back, push away it to the suit to the fixed axle that corresponds through the push rod subassembly of its one side, later rotate along with the rotation of carousel, when it rotates to the top, synchronous start rotating assembly and UV silk screen printing subassembly, the process of UV silk screen printing is carried out to the survey periphery of bottle lid, though rotate after the silk screen printing, when it rotates the below, through unload lid subassembly with fixed epaxial silk screen printing after the lid lift off can, the carousel rotates the angle of a fixed axle during every, then the push rod impels once, the bottle lid suit is one, repeat above-mentioned step, then can accomplish the feed one by one of bottle lid, then suit one by one, silk screen printing one by one, unload one by one, later along with ejection of compact endless conveyor belt output can accomplish automatic batch silk screen printing process.
