Description

Technical Field

[0001] The utility model relates to the technical field of display screen lamination, and particularly relates to an S-shaped curved surface product lamination device. Background Art

[0002] At present, with the rapid development of flexible OLED (organic light-emitting diode) display screens, flexible OLED display screens are widely used in all walks of life. Especially in the automotive industry, the form of in-vehicle displays has undergone great changes. The products of flexible OLED display screens have evolved from a planar form to an S-shaped curved surface form. When laminating products, it is necessary to laminate S-shaped curved surface products with both concave and convex forms simultaneously at the same station, and the lamination of the two forms is continuous and uninterrupted. At present, the existing curved surface lamination equipment on the market can only laminate one form of concave or convex, and cannot realize laminating S-shaped curved surface products with both concave and convex forms at the same station. Therefore, how to design a device that can meet the lamination of S-shaped curved surface products has become an urgent problem to be solved. Summary of the Utility Model

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide an S-shaped curved surface product lamination device to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problems is as follows:

[0005] According to one aspect of the utility model, an S-shaped curved surface product lamination device is designed, including:

[0006] A profiling jig, with an S-shaped curved surface at the bottom, and a number of vacuum adsorption units are distributed on the S-shaped curved surface. The bottom of the profiling jig is used to adsorb and fix the S-shaped CG.

[0007] A carrier film, with the top used to carry the flexible film. The carrier film is arranged below the profiling jig. The left and right ends of the carrier film are respectively connected with carrier film clamping members for clamping the ends thereof. At least one of the carrier film clamping members is connected with a first driving component for driving it to move in the Z direction and the X direction.

[0008] An attaching roller, arranged below the carrier film. The attaching roller is rotatably connected to an attaching roller bracket. The attaching roller bracket is connected with a second driving component for driving it to move in the Z direction and the X direction. The second driving component is used to drive the attaching roller to lift the carrier film so that the flexible film contacts the S-shaped CG and drive the attaching roller to move in the X direction in cooperation with the movement in the Z direction to realize the lamination of the flexible film and the S-shaped CG.

[0009] With the above technical solution, when the flexible film needs to be attached to the S-shaped CG (glass cover plate), the S-shaped CG is placed at the bottom of the profiling fixture and adsorbed and fixed by the vacuum adsorption unit. The flexible film is placed on top of the carrier film. Then, the second driving component drives the attachment roller bracket to rise, so that the attachment roller jacks up the carrier film, and thus the flexible film placed on top of the carrier film contacts the S-shaped CG. After that, the second driving component drives the attachment roller bracket to drive the attachment roller to move in the X direction and cooperate with the movement in the Z direction to realize the attachment of the flexible film to the S-shaped CG. While the second driving component drives the attachment roller bracket to drive the attachment roller to move in the X direction and the Z direction, the first driving component drives the carrier film clamping member to move in the X direction and the Z direction so that the carrier film is always under substantially the same tension, ensuring the smooth attachment of the flexible film to the S-shaped CG. Thus, the attachment of the S-shaped curved surface product is realized, and the attachment effect is good and stable, solving the technical problem that the existing attachment device cannot realize the attachment of the S-shaped curved surface product.

[0010] In order to better solve the above technical defects, the present utility model also has a better technical solution:

[0011] In some embodiments, it further includes an upper cavity and a lower cavity. The upper cavity and the lower cavity are corresponding up and down, and one of them is connected with a lifting driving component for driving its lifting. When the lifting driving component drives the upper cavity and the lower cavity to contact, the inside of the upper cavity and the inside of the lower cavity form a sealed chamber. One of the upper cavity and the lower cavity is connected with a vacuum pump for evacuating the sealed chamber. The profiling fixture, the first driving component and the second driving component are all arranged in the sealed chamber, and the profiling fixture is connected with the upper cavity, and the second driving component is connected with the lower cavity. Thus, the attachment of the flexible film to the S-shaped CG can be realized in a vacuum environment, reducing the probability of bubbles generated during the attachment process and improving the yield rate of product attachment.

[0012] In some embodiments, CG fixing members for fixing the S-shaped CG are respectively fixed on the front and rear sides of the profiling fixture.

[0013] In some embodiments, the first driving component includes a first Z-direction driving unit and a first X-direction driving unit. The driving end of the first Z-direction driving unit is drivingly connected with the first X-direction driving unit for driving the first X-direction driving unit to move in the Z direction. The driving end of the first X-direction driving unit is drivingly connected with the carrier film clamping member for driving the carrier film clamping member to move in the X direction.

[0014] In some embodiments, the second driving component includes a second Z-direction driving unit and a second X-direction driving unit. The driving end of the second Z-direction driving unit is drivingly connected with the second X-direction driving unit for driving the second X-direction driving unit to move in the Z direction. The driving end of the second X-direction driving unit is drivingly connected with the attachment roller bracket for driving the attachment roller bracket to move in the X direction.

[0015] In some embodiments, the second Z-direction driving unit is a lifting cylinder, and an electro-hydraulic proportional valve is connected to the connecting pipeline between the lifting cylinder and the air source. The second X-direction driving device is a linear slide table, an electric push rod, or a cylinder.

[0016] In some embodiments, the first Z-direction driving unit and the first X-direction driving unit are cylinders, electric push rods, or linear slide tables.

[0017] In some embodiments, the CG fixing member includes a connecting plate, a driving cylinder fixed on the connecting plate, and a fixing pressing plate connected to the driving end of the driving cylinder. One end of the fixing pressing plate is located below the profiling jig. When the driving cylinder drives the fixing pressing plate to move towards the bottom surface of the profiling jig, it can abut against the S-shaped CG adsorbed on the bottom of the profiling jig.
