Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to a cover glass front protective film coating fixture. Background Technology

[0002] In cover glass, to prevent the front protective film from extending beyond the cover, it is designed to be 0.5mm smaller on each side than the cover glass to allow space for process application. The front protective film is typically applied to the cover glass using an automatic laminating machine or a manual laminating fixture. However, in situations such as small module factories, frequent line changes in heavy-duty areas, multiple machine types, and small order volumes, automatic laminating machines are not suitable, requiring manual laminating using a fixture. Currently, the length and width of the front protective film groove in the laminating fixture are the same as the length and width of the cover glass groove. Because the front protective film is smaller than the cover glass, manual application cannot guarantee that it will be centered, resulting in misaligned application or even extending beyond the cover glass's shape, affecting subsequent installation and testing.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cover glass front protective film coating fixture.

[0005] The technical solution of this utility model is as follows: This utility model provides a cover glass front protective film coating fixture, comprising: a fixture body, wherein a first groove is formed on the fixture body corresponding to the shape of the cover glass, the depth of the first groove is 1mm greater than the thickness of the cover glass, and the length and width dimensions of the first groove are 0.1mm greater on each side than the corresponding length and width dimensions of the cover glass; a second groove is provided at the bottom of the first groove corresponding to the shape of the front protective film, the depth of the second groove is 0.2mm-0.4mm greater than the thickness of the front protective film, and the length and width dimensions of the second groove are 0.1mm greater on each side than the corresponding length and width dimensions of the front protective film; the fixture body forms first hollow grooves on both sides of the first groove for picking up the cover glass; and the fixture body forms a second hollow groove in the middle of the second groove for pressing the front protective film.

[0006] Furthermore, the length and width of the first hollowed-out groove are both greater than or equal to 20mm.

[0007] Furthermore, the length of the second hollowed-out groove is greater than or equal to 80 mm, and the width is greater than or equal to 40 mm.

[0008] The advantages of this utility model by adopting the above solution are: it can ensure that the front protective film is centered on the cover glass, avoiding customer complaints caused by problems such as uneven or crooked application, and also avoiding structural interference and assembly process errors caused by the front protective film exceeding the shape of the cover glass. It has the advantages of low cost and good effect. Attached Figure Description

[0009] Figure 1 This is a front view of an embodiment of the present invention.

[0010] Figure 2 This is a rear view of an embodiment of the present invention.

[0011] Figure 3 This is a cross-sectional view of an embodiment of the present invention. Detailed Implementation

[0012] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] Please refer to the following: Figures 1 to 3 In this embodiment, the present invention provides a cover glass front protective film coating fixture, comprising: a fixture body 1, which is made of bakelite with a thickness of approximately 10mm. A matching first groove 2 is formed on the fixture body 1 corresponding to the shape of the cover glass. The first groove 2 is used to place the cover glass during film application, thereby achieving positioning of the cover glass. The depth of the first groove 2 is 1mm greater than the thickness of the cover glass, and the length and width dimensions of the first groove 2 are 0.1mm larger on each side than the corresponding length and width dimensions of the cover glass. That is, the first groove 2 leaves a 0.1mm gap on each side relative to the length and width directions of the cover glass, which facilitates the placement and positioning of the cover glass within the first groove 2 and prevents it from slipping out. The bottom of the first groove 2 corresponds to the shape of the front protective film and has a second groove 3. The depth of the second groove 3 is 0.2mm-0.4mm greater than the thickness of the front protective film, and the length and width of the second groove 3 are 0.1mm larger on each side than the corresponding length and width of the front protective film. The size of the second groove 3 is smaller than that of the first groove 2, so that the position of the second groove 3 can more accurately match the corresponding attachment position. The jig body 1 has first hollow grooves 4 formed on both sides of the first groove 2 for picking up the cover glass. In this embodiment, the length and width of the first hollow grooves 4 are both greater than or equal to 20mm. In order to facilitate picking up the cover glass, the length and width of the first hollow grooves 4 can also be adjusted as needed. The jig body 1 has a second hollow groove 5 formed in the middle of the second groove 3 for pressing the front protective film. The length of the second hollow groove 5 is greater than or equal to 80mm and the width is greater than or equal to 40mm, which can ensure that there is enough space to press the front protective film so that the front protective film adheres to the cover glass.

[0014] Please continue to refer to the following: Figures 1 to 3 When using the fixture in this solution, first place the front protective film on the second groove 3, then place the cover glass on the first groove 2, and then slide and press the front protective film from below the fixture through the second hollow groove 5 so that the front protective film adheres to the cover glass. Then, remove the cover glass by taking out both sides through the first hollow groove 4.

[0015] In summary, the advantages of this solution are: it ensures that the protective film is centered on the cover glass, avoiding customer complaints caused by uneven or crooked application; it also avoids structural interference and assembly errors caused by the protective film extending beyond the cover glass's shape. It boasts the advantages of low cost and high effectiveness.

[0016] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
