Description

Technical Field

[0001] The utility model relates to the technical field of film tearing, and more particularly to a pull-bar structure for convenient film tearing. Background Art

[0002] In industry and production lines, transparent double-sided tape is often used to fix electronic components, plastic frames, iron frames, light guide plates, etc. During the general operation, the operator peels the transparent double-sided tape from the substrate through the release film protective layer, so that the sticky side is attached to the product. After that, the release film protective layer on the other side needs to be peeled off to expose the sticky part on the other side and apply it to the target surface, such as Figure 1 and Figure 2 As shown, when the transparent double-sided tape is attached to the adhesive frame, it is impossible to distinguish whether the a-end or the b-end is the pull-bar 102 from the transparent release film protective layer 101 on its surface, which makes it inconvenient to tear off the transparent release film on the production line, and is not conducive to improving production efficiency and operational convenience. Therefore, in order to improve the convenience and efficiency of operating the transparent double-sided tape on the production line, it is necessary to provide a pull-bar structure that is convenient for tearing off the film.

[0018] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] Please refer to Figure 3The embodiment of the present invention provides a pull-bar structure for convenient film tearing, including a double-sided adhesive tape 1 and a release film 2. The following is a detailed description of the various components of this embodiment in conjunction with the accompanying drawings.

[0020] like Figure 3 and Figure 4 As shown, the release film 2 can cover the entire surface of the double-sided adhesive tape 1. The surface of the double-sided adhesive tape 1 is bonded to the release film 2 through its own viscosity. The shape of one end of the release film 2 corresponds to the shape of the double-sided adhesive tape 1. The part of the release film 2 extending from the double-sided adhesive tape 1 is set as a pull-bar 21. The pull-bar 21 can be separated from the sticky surface of the double-sided adhesive tape 1. One of the corners of the pull-bar 21 is provided with a chamfer 22.

[0021] In this embodiment, the release film 2 may preferably be a transparent PET release film.

[0022] Specifically, the release film 2 can be peeled off from the double-sided tape 1. The release film 2 can protect the double-sided tape 1. When the double-sided tape 1 needs to be used, the release film 2 can be torn off to expose the sticky part of the double-sided tape 1 and apply it to the target surface.

[0023] Furthermore, the double-sided tape 1 can be configured as a transparent double-sided tape.

[0024] like Figure 5 As shown, in a specific implementation, the design of the pullbar 21 allows the user to avoid using tools or fingers to directly contact the sticky surface of the transparent double-sided adhesive tape 1 when using the transparent double-sided adhesive tape 1, and can easily grab and tear off the transparent release film 2. The design of the chamfer 22 allows the operator to visually identify the position of the pullbar 21 (located at end a in the figure) from the surface of the transparent release film 2, which facilitates and quickly grabs and tears off the transparent release film 2, thereby improving work efficiency and convenience.

[0025] In addition, the design of the chamfer 22 can also reduce stress concentration during tearing, making the release film 2 easier to peel off.

[0026] Furthermore, the chamfer 22 can be configured as an oblique chamfer or a round chamfer.

[0027] The degree of the bevel chamfer 22 can be set to 45° or 30°, preferably 45°, for ease of production and processing and quick visual identification. This embodiment does not limit the degree of the bevel chamfer 22. The rounded chamfer can process the edge of one corner of the laba 21 into a smooth arc to eliminate sharp edges and reduce the risk of scratches during manual operation.

[0028] Preferably, the double-sided adhesive 1 can be configured as acrylic pressure-sensitive adhesive, elastomer pressure-sensitive adhesive or resin pressure-sensitive adhesive.

[0029] The double-sided adhesive tape 1 of this embodiment is preferably configured as an acrylic pressure-sensitive adhesive. Due to its temperature resistance and chemical resistance, acrylic pressure-sensitive adhesive is very suitable for use in electronic products and can provide long-term adhesion and good transparency.

[0030] To sum up, the utility model provides a chamfer on one of the corners of the pull-bar. When the double-sided tape is attached to the adhesive frame, the pull-bar with the chamfered structure can be quickly identified visually from the surface of the release film. The production line operator can quickly grab the pull-bar and tear off the release film. This fool-proof design can help ensure the accuracy of each operation, significantly improve work efficiency and convenience, and also improve the overall quality and consistency of the product.

[0031] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
