Description

Technical Field

[0001] The invention relates to the technical field of quantum film production, in particular to a quantum dot film roller coating device with a stabilizing mechanism. Background Art

[0002] Quantum dots are a type of semiconductor material composed of zinc, cadmium, selenium and sulfur atoms, with three dimensions all in the nanometer range. Currently, quantum dot film is the most important application of quantum dot display technology. However, it is generally believed that the structure of quantum dot film is a sandwich, that is, liquid quantum dot glue is coated on a layer of barrier film, and then heated or UV-cured or cured and then bonded.

[0003] In the prior art, the coating method of quantum dot film is generally to directly pour quantum dot liquid on the surface of the substrate, and then coat the quantum dot glue on the surface of the substrate through a coating roller.

[0004] However, when this method is used to coat the surface of the substrate, when the substrate is initially coated, the amount of quantum dot glue on the surface of the substrate is large, and the coated quantum dot glue is correspondingly thicker. As the coating roller is applied, the quantum dot glue gradually becomes thinner; if the quantum dot liquid is not added in time, the surface of the substrate can easily lead to uneven coating; in view of this, we propose a quantum dot film roller coating device with a stabilizing mechanism.

The tops of the diverter plate 19 and the oblique plate 20 are provided with diverter grooves 21, and the inner bottom surface of the diverter grooves 21 is fixedly connected with diverter blocks 22. The number of diverter blocks 22 is arranged in several groups, and the several groups of diverter blocks 22 are staggered and distributed at equal intervals.

[0024] The top end surface of the mounting seat 1 is fixedly connected with a drying device 26, the top end surface of the mounting seat 1 is fixedly connected with a frame 27, the side wall of the frame 27 is rotatably connected with a winding roller 28, the top end surface of the mounting seat 1 is fixedly connected with a driving motor 29, the output end of the driving motor 29 is fixedly connected with an output shaft, the side wall of the output shaft is transmission-connected with a belt three 30, the belt three 30 is transmission-connected with the winding roller 28, the inner wall of the frame 27 is fixedly connected with a cross bar 31, the side wall of the cross bar 31 is rotatably connected with a connecting sleeve, the connecting sleeve is fixedly connected with a lower pressure roller 33, the side wall of the frame 27 is fixedly connected with an arc-shaped telescopic rod 32, and the end of the arc-shaped telescopic rod 32 away from the frame 27 is fixedly connected to the side wall of the lower pressure roller 33.

[0025] The driving motor 1 29 rotates to drive the winding roller 28 to rotate through the transmission of the belt 3 30 to reel up the quantum dot film. The lower pressure roller 33 promotes the compactness of the reel under the pressure of the arc-shaped telescopic rod 32.

[0026] The top end face of the mounting seat 1 is fixedly connected to a frame body 2 34, the inner wall of the frame body 2 34 is rotatably connected to a rotating frame 35, the inner wall of the rotating frame 35 is rotatably connected to a tensioning roller 36, the side wall of the frame body 2 34 is fixedly connected to a driving motor 2 37, the output end of the driving motor 2 37 is fixedly connected to a connecting frame 38, the connecting frame 38 is fixedly connected to the rotating frame 35, the top end face of the mounting seat 1 is fixedly connected to a frame body 39, the inner top surface of the frame body 39 is fixedly connected to an elastic telescopic rod 40, and the bottom end of the elastic telescopic rod 40 is fixedly connected to a downward pressure arc plate 41.

[0027] The driving motor 2 37 is started to drive the rotating frame 35 to rotate, so that the tensioning roller 36 tightens the film, thereby improving the stability of subsequent coating and winding. The downward pressure arc plate 41 pushes the film to move downward. The pressure of the film in the middle of the downward pressure arc plate 41 is relatively small. During the movement of the film, it will gradually move toward the center of the downward pressure arc plate 41, thereby promoting the centering of the film and improving the effect of film coating.

[0028] The hydraulic cylinder 3 is pressed downward to move the movable frame 4 downward until it reaches the surface of the coating roller 11 and the substrate, and then the servo motor 6 is started to drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the driven shaft 10 and the driven shaft 2 13 through the rotation of the belt 1 12 and the belt 2 15 respectively. The rotation of the rotating shaft 7 drives the rotating sleeve 9 to rotate, and further drives the contact roller 18 to rotate, pouring the quantum dot glue into the diversion groove 21. The quantum dot glue moves with the movable plate 23 under the action of gravity. While passing through the diversion block 22, the quantum dot glue is dispersed to both sides to ensure the uniformity of the glue distribution.

[0029] The quantum dot glue enters the gap between the movable plate 23 and the diverter plate 19, and then flows downward along the gap. The contact roller 18 contacts the bottom of the diverter plate 19, so that the quantum dot glue can evenly cover the surface of the contact roller 18.

A slide groove 24 is opened on the side wall of the movable plate 23, and the slide groove 24 is slidably connected to the connecting rod 25.

[0033] In the present invention, when in use, the servo motor 6 is started to drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the driven shaft 10 and the driven shaft 2 13 respectively through the rotation of the belt 12 and the belt 2 15. The rotation of the rotating shaft 7 drives the rotating sleeve 9 to rotate, and further drives the contact roller 18 to rotate. The contact roller 18 contacts the bottom of the diverter plate 19, so that the quantum dot glue can cover the surface of the contact roller 18, and then the quantum dot glue on the contact roller 18 is transferred to the surface of the rotating sleeve 9 and the coating roller 11 in turn to coat the quantum dot film.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
