Description

Technical Field

[0001] The present invention relates to the field of display screen production, and in particular to a feeding and laminating device for display screen production. Background Art

[0002] During the production process of electronic display screens, in order to protect the screens of the electronic display screens from damage, the electronic display screens need to be laminated. Currently, the electronic display screens are generally laminated using a laminating roller. However, since the electronic display screens are exposed to the outside for a long time, if the surface of the electronic display screens is not cleaned before laminating, it is easy to cause dust on the surface of the electronic display screen, resulting in poor laminating effect, bubbles on the surface, or uneven film.

[0003] For this purpose, there is a feeding and laminating device for the production of electronic display screens with patent number CN221697913U to solve the above problems. However, it has the following defects when used. It is difficult to clean the surface of the display screen by only using a series of cleaning rollers made of flexible materials such as flexible brushes or sponges, thereby affecting the subsequent laminating work. Summary of the Invention

[0004] The purpose of the present invention is to provide a feeding and laminating device for display screen production.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0018] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] A feeding and laminating device for display screen production includes a frame 1, wherein a conveyor belt 2 for conveying the display screen is installed between the frame 1:

[0020] A box body 3 is mounted on the frame 1, and an arc-shaped shell 4 with an opening facing downward is mounted at the bottom of the box body 3. A cleaning roller 5 is arranged in the arc-shaped shell 4. A guide plate 6 and a purge pipe 7 are sequentially arranged in the arc-shaped shell 4 downstream of the cleaning roller 5. A dust removal pipe 8 connected to an exhaust fan is also arranged on the top of the arc-shaped shell 4.

[0021] like Figure 1 As shown, one side wall of the open end of the arc-shaped shell 4 protrudes outward with an arched portion 10 for accommodating the purge pipe 7. The bottom of the side wall of the purge pipe 7 is inclined downwardly provided with multiple groups of air outlet nozzles 11, and the air outlet nozzles 11 are arranged on the same side as the cleaning roller 5;

[0022] A laminating mechanism 9 is provided in the box body 3 at the downstream of the arc-shaped shell 4. The laminating mechanism 9 includes a mounting plate 91 longitudinally arranged in the box body 3. A plurality of groups of T-shaped rods 92 penetrating the side wall are provided at the upstream of the mounting plate 91. A fixing plate 93 is fixed to the bottom end of the plurality of groups of T-shaped rods 92, and nuts 13 are screwed on the rod bodies of the T-shaped rods 92 above the mounting plate 91. A spring 94 is provided on the outer sleeve of the T-shaped rods 92 above the fixing plate 93. A guide roller 95 and a die roller 96 are staggered above and below the fixing plate 93. A vertical plate 97 for fixing the corresponding guide roller 95 and the die roller 96 is provided at the bottom of the plate 93. Both ends of the guide roller 95 and the die roller 96 are provided with a rotating shaft fixed on the corresponding vertical plate 97 through a bearing. An electric push rod 98 is provided at the downstream of the mounting plate 91. The output shaft of the electric push rod 98 is connected to the cutting knife group 99. In this embodiment, a mounting rod 12 is provided on the output shaft of the electric push rod 98. The cutting knife group 99 is arranged at the bottom of the mounting rod 12, and the bottom end of the cutting knife group 99 is located above the die roller 96.

[0023] In this embodiment, the cleaning roller 5 is driven by a motor, and the bottom end of the cleaning roller 5 passes through the opening of the arc-shaped shell 4 and contacts the end surface of the display screen on the conveyor belt 2.

[0024] like Figure 1 As shown, the guide plate 6 is arranged at an angle, the top end of the guide plate 6 is fixedly connected to the inner wall of the arc-shaped shell 4, and the bottom end of the guide plate 6 is arranged on the same side as the cleaning roller 5.

[0025] like Figure 1 As shown, the guide roller 95 is located above the die roller 96 , and the guide roller 95 is located between the arc-shaped shell 4 and the die roller 96 , and the bottom end of the die roller 96 contacts the top surface of the display screen on the top of the conveyor belt 2 .

[0026] During use, the conveyor belt 2 plays a conveying role on the display screens placed sequentially on the top thereof. When the display screen moves to the position below the cleaning roller 5, the rotating cleaning roller 5 can play a preliminary cleaning role on the top surface of the display screen. At the same time, the fan introduces a strong airflow into the purge pipe 7 and is sprayed out by a plurality of air outlet nozzles 11, thereby playing a purge and cleaning role on the top surface of the display screen after the preliminary cleaning. At this time, the exhaust fan extracts the dust and other impurities diffused in the arc-shaped shell 4 after the purge or cleaning through the dust removal pipe 8 and the arc-shaped shell 4, thereby playing a multi-stage cleaning role on the top surface of the display screen, so as to improve the subsequent lamination quality.

[0027] When the cleaned display screen moves to the position just below the laminating mechanism 9, the guide roller 95 can guide the film to make it close to the top surface of the display screen, and the die roller 96 can press the display screen with the film to make it fully fit. At this time, the die roller 96 is affected by the moving display screen and other components and rotates together. During the rotation, the film on the top of the display screen is pressed. Then the electric push rod 98 drives the cutting knife group 99 to move up and down through the mounting rod 12, and then cuts the film connection between the two adjacent groups of display screens, realizing the laminating mechanism 9 to press and cut the film on the display screen with the film in turn, and when the die roller 96 presses the film above the display screen, At this time, the conveyor belt 2 may cause a slight up and down swing when driving the display screen to move. At this time, under the influence of the top pressure of the undulating display screen, the die roller 96 drives the T-bar 92 to move upward in the through hole on the mounting plate 91 through the vertical plate 97 and the fixed plate 93 and compresses the spring 94 to prevent the die roller 96 from being fixed in position, causing the conveyor belt 2 to drive the display screen to fluctuate slightly up and down and get it stuck, thereby affecting the conveyor belt 2 to drive the display screen to move or affecting the die roller 96 to press the film on the display screen. In the above process, by adjusting the position of the nut 13, when the T-bar 92 slides downward in the through hole on the mounting plate 91, the mounting plate 91 presses against the nut 13 to limit the downward movement of components such as the fixed plate 93, the vertical plate 97 and the die roller 96.

[0028] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
