Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] Embodiment 1, by Figures 1 to 5The present invention provides a coating platform centering and correction control device, comprising a PLC correction controller 1, characterized in that: the PLC correction controller 1 is installed at one end of the top of the coating platform bracket 2, and a coating roller 3 and a scraper roller 4 are rotatably arranged on the coating platform bracket 2, and the scraper roller 4 is located on the top of the coating roller 3, and a servo motor 5, two millimeter-level background suppression photoelectric sensors 1 6, two positioning scales 7, two millimeter-level background suppression photoelectric sensors 2 8, a supporting platform 9, a servo electric cylinder 1 11 and a servo electric cylinder 2 13 are fixedly arranged on the coating platform bracket 2, and the output shaft of the servo motor 5 is fixedly connected to one end of the scraper roller 4, and the two millimeter-level background suppression photoelectric sensors 1 6 and the two positioning scales 7 are respectively located on the top of the coating platform bracket 2 At the two end positions near the side of the paint roller 3, two millimeter-level background suppression photoelectric sensors 28 are respectively located at the two end positions of the other side of the top of the coating platform bracket 2 near the paint roller 3, the support platform 9 is located in the middle position of one side of the paint roller 3 and is fixedly connected to the coating platform bracket 2, and the two ends of the top of the support platform 9 are respectively provided with a side baffle plate 10 and a side baffle plate 2 12, the side baffle plate 10 is connected to one end of the top of the support platform 9 through a servo electric cylinder 11 and is closely connected to the support platform 9, the side baffle plate 2 12 is connected to the other end of the top of the support platform 9 through a servo electric cylinder 2 13 and is closely connected to the support platform 9, and one end of the side baffle plate 10 and the side baffle plate 2 12 are closely connected to the paint roller 3 and the scraper roller 4;

[0032] When in use, the entire correction device is controlled by the PLC correction controller 1. The millimeter-level background suppression photoelectric sensor 6 and the positioning ruler 7 can accurately monitor the position of the release paper before coating. The positioning ruler 7 plays a positioning role. When the millimeter-level background suppression photoelectric sensor 6 is working, it monitors whether the edge line of the release paper and the positioning ruler 7 are offset. If offset occurs, the offset amount is monitored, and then the monitoring data is fed back to the PLC correction controller 1. The millimeter-level background suppression photoelectric sensor 8 can accurately monitor the position of the release paper and the coating material after coating. If the distance between the edge of the coating material and the edge of the release paper increases or decreases, it means that the coating is When the release paper is offset, the monitoring data is fed back to the PLC deviation correction controller 1. When the release paper is offset, the PLC deviation correction controller 1 controls the servo electric cylinder 11 and the servo electric cylinder 2 13 to work. The servo electric cylinder 11 drives the side baffle plate 10 to move and adjust on the top of the support platform 9. The servo electric cylinder 2 13 drives the side baffle plate 2 12 to move and adjust on the top of the support platform 9.

The side baffle plate 10 and the side baffle plate 2 12 realize the material blocking function, and can adjust the coating edge of the coating material, so as to realize centered coating, avoid offset, and improve coating quality.

[0033] The outer side of the scraper roller 4 is provided with a strip section 14, and the distance from the arcuate outer surface of the scraper roller 4 to the center line of the scraper roller 4 increases in clockwise direction from point A to point B of the strip section 14;

[0034] When adjusting the coating thickness, the scraper roller 4 is driven by the servo motor 5 to rotate a certain angle. Since the distance from the center line of the scraper roller 4 in the clockwise direction from point A to point B along the strip section 14 increases successively, when the scraper roller 4 rotates, the distance between the scraper roller 4 and the paint roller 3 increases, so that the coating thickness can be adjusted. After the adjustment is completed, the servo motor 5 stops rotating. At this time, the scraper roller 4 is in a stationary state, and the distance between the bottom surface of the scraper roller 4 and the paint roller 3 remains unchanged. During the operation of the scraper roller 4, the excess coating material is scraped off, thereby realizing the adjustment of the coating thickness.

The arc deformable metal strip 18 can also be deformed, so that after the scraper roller 4 is rotated and adjusted, the arc deformable metal strip 18 can always fit and connect with the arc surface of the scraper roller 4, so as to avoid the occurrence of gaps and leakage.

[0037] An inner groove 22 connected to the gap 21 is provided at one end of the main body 17 near the arc-shaped deformable metal strip 18.

The friction between the cam 27 and the lifting push plate 29 can be reduced by the first rotating wheel 28. When the cam 27 rotates, the limit push plate 40 is synchronously driven to swing, and the limit push plate 40 drives the rotating wheel three 34, thereby driving the L-shaped turning arm 31 to rotate around the rotating shaft 32. At this time, the moving push plate 35 is pushed to move by the rotating wheel two 33, and the moving push plate 35 drives The movable push rod 36 moves, and during the lateral movement of the movable push rod 36, it moves upward along the inclined support guide plate 38, thereby forming an inclined movement.

At this time, the movable push rod 36 forms an inclined movement, thereby driving the other end of the arc-shaped deformable metal strip 18 to move obliquely upward, so that the other end of the arc-shaped deformable metal strip 18 is fully fitted with the bottom surface of the scraper roller 4, and both ends of the arc-shaped deformable metal strip 18 are subjected to traction, so that the arc-shaped deformable metal strip 18 is deformed as a whole, so that the upper surface of the arc-shaped deformable metal strip 18 is fully fitted with the side surface of the scraper roller 4 to avoid leakage.
