Description

Technical Field

[0001] The present application belongs to the technical field of fixtures, and in particular relates to a fixture for attaching PET film to an LED board. Background Art

[0002] With the recovery of consumption level and the development of automobile intelligence, the demand for display screens is increasing. In order to better meet user needs, new display technologies have also begun to be developed and mass-produced, such as Micro-LED and Micro-Led, which also bring about the demand for supporting new materials, new processes, new equipment, etc. The requirements for LED printed circuit boards are also getting higher and higher, especially the requirements for appearance quality. The special white oil reflectivity requirements of LEDs lead to poor appearance yield during the production process, especially the main cost of titanium dioxide in white oil. When it comes into contact with metal during production, inspection, and transportation, it will turn black, resulting in even worse reflectivity.

[0003] In order to solve the problem of poor process appearance, the industry often uses PET film to protect the surface to prevent process pollution, scratches and foreign matter. However, PET film is currently covered on the lamp surface by manual film application, which has poor efficiency and is easy to deviate. Utility Model Content

[0004] The purpose of the embodiment of the present application is to provide a fixture for attaching PET film to an LED board, which, by setting positioning columns on the fixture plate, makes it less likely to cause deviation when attaching the film, thereby solving at least one technical problem involved in the background technology.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] An embodiment of the present application provides a PET film fixture for LED boards, comprising a fixture plate for placing LED boards, wherein the length-to-width ratio of the fixture plate is ≥20 mm on a single side of the length and width of the LED board, the LED board is provided with alignment holes, and the fixture plate is provided with positioning columns that cooperate with the alignment holes.

[0007] As a preferred improvement of the present invention, the length of the positioning column is greater than the sum of the thickness of the fixture plate and the thickness of the LED board by more than 3 mm.

[0008] As a preferred improvement of the present invention, the positioning column is a plastic nail.

[0009] As a preferred improvement of the present invention, the fixture plate is provided with an assembly hole for fixing the positioning column.

[0010] As a preferred improvement of the present invention, the thickness of the fixture plate is ≥1.0 mm.

[0011] As a preferred improvement of the present invention, the fixture plate is a polypropylene (PP) plate.

[0012] As a preferred improvement of the present invention, the number of the positioning posts is four, and the four positioning posts are respectively arranged at four corner positions of the fixture plate.

[0013] Compared with the prior art, this application has the following beneficial effects:

[0014] 1. By setting the positioning column on the jig plate, it is not easy to deviate when the film is applied;

[0015] 2. The length of the positioning column is at least 3 mm greater than the sum of the thickness of the fixture plate and the thickness of the LED board, so that the LED board can be inserted into the positioning column and prevent the LED board from being unable to hang on the positioning column due to warping. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative work, among which:

[0018] Figure 2 This is a structural schematic diagram of the LED board PET film pasting fixture provided by the utility model. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a PET film fixture for LED board, including a fixture plate 1 for placing an LED board 2, the length-to-width ratio of the fixture plate 1 is ≥20mm on a single side of the length and width of the LED board 2, an alignment hole 21 is provided on the LED board 2, and the fixture plate 1 is provided with a positioning column 11 that cooperates with the alignment hole 21.

[0022] The length of the positioning column 11 is greater than the sum of the thickness of the fixture plate 1 and the thickness of the LED board 2 by more than 3 mm, so that the LED board can be easily inserted into the positioning column and prevent the LED board from being unable to hang on the positioning column due to warping.

[0023] The positioning posts 11 are plastic nails. There are four positioning posts 11 in number, and the four positioning posts 11 are disposed at four corners of the jig plate 1 , so that the film is not easily misaligned during application.

[0024] The fixture plate 1 is provided with an assembly hole (not numbered) for fixing the positioning column 11. The diameter of the positioning column 11 is consistent with the hole diameter of the assembly hole. The assembly hole needs to be fool-proof to ensure correctness.

[0025] The thickness of the jig plate 1 is ≥1.0 mm. The jig plate 1 is a polypropylene PP plate.

[0026] It should be noted that the LED board 2 needs to be attached with a PET film 3. In this application, a release paper is provided on the PET film, which is used to protect the surface of the PET film. During the manufacturing process, the release paper needs to be torn off and applied to the LED board surface. The PET film uses a laser to gong out the position of the jig alignment hole so that it can be inserted into the positioning column for alignment. In addition, a semicircular release paper with a diameter of 10mm is reserved at the four corners of the release paper so that the release paper can be easily torn off and the operation is convenient.
