Description

Technical Field

[0001] This invention relates to the field of home appliance manufacturing technology, and more specifically, to a jig for reverse-attaching adhesive strips for full-screen televisions. Background Technology

[0002] With the rapid development of LCD TVs and monitors, more and more users are enthusiastic about full-screen TVs. Compared with traditional bezel-less TVs, full-screen TVs do not have conspicuous large bezels, making them more aesthetically pleasing. Most existing full-screen TVs or monitors are supported by a mid-shell, specifically relying on a 5mm folded edge around the mid-shell as the support surface. The LCD screen is supported above the folded edge, and an optical film is placed below it. Because the surface of the optical film has a layer of micron-level optical microstructures, it is extremely susceptible to damage. Therefore, a buffer silicone strip is attached to the lower surface of the mid-shell folded edge. Currently, LCD TV manufacturers use a purely manual method to manually attach the buffer silicone strip to the lower surface of the mid-shell folded edge. This manual attachment is inefficient and labor-intensive. Furthermore, because the silicone strip needs to be attached to the lower surface of the mid-shell folded edge, it is not only limited by space but also very difficult to attach during production. Moreover, manually attached strips are subject to uneven force and are prone to falling off.

[0003] Therefore, how to solve the problem of manually pasting buffer silicone strips on the lower surface of the middle shell edge by pure manual means is not only limited by space and very difficult to do during production operations; but also the problem that the manually pasted strips are unevenly stressed and easy to fall off has become an important technical problem that professionals in this field need to solve. Summary of the Invention

[0004] This invention provides a reverse-attachment fixture for adhesive strips in full-screen TVs, which solves the problem that manually attaching buffer silicone strips to the lower surface of the folded edge of the middle shell is not only limited by space and very difficult to do during production, but also results in uneven force on the manually attached adhesive strips, making them prone to falling off.

[0005] The adhesive strip reversing fixture for full-screen televisions of the present invention adopts the following technical solution:

[0006] A jig for reversing adhesive strips for full-screen TVs is used to attach adhesive strips to the lower surface of the folded edge of the middle shell. The jig comprises an attachment body positioned below the folded edge of the middle shell. The upper surface of the attachment body has a guide groove and an attachment surface. The attachment surface is located at a first end within the guide groove. A second end of the guide groove, opposite to the first end, has an inlet for the adhesive strip to pass through. The attachment surface is a curved surface whose height gradually decreases along the direction from the first end to the second end of the guide groove. The adhesive strip is inserted through the inlet and positioned on the attachment surface. By pulling the attachment body obliquely upwards, the adhesive strip is reversibly attached to the lower surface of the folded edge of the middle shell.

[0007] Preferably, the covering surface includes multiple curved surfaces forming a smooth transition continuous curved surface, with each pair of adjacent curved surfaces arranged tangentially, and the curvature of each curved surface gradually decreasing along the direction from the first end to the second end of the guide groove.

[0008] Preferably, a lubricating film is provided on the continuous curved surface.

[0009] Preferably, the width of the guide groove is greater than the width of the silicone strip and less than the width of the folded edge of the middle shell.

[0010] Preferably, it also includes a handle, the guide groove is disposed on one side of the upper surface of the adhesive body, the handle is disposed on the other side of the upper surface of the adhesive body, and a support block is provided between the handle and the adhesive body.

[0011] Preferably, the attachment body, the support block, and the handle are integrated into a single structure.

[0012] Preferably, the covering surface and the penetration opening are spaced apart.

[0013] Preferably, the outer surface of the handle is marked with the width specification of the guide groove.

[0014] Preferably, the handle is provided with an anti-slip component.

[0015] Preferably, the anti-slip component is made of silicone particles.

[0016] The beneficial effects of this invention are as follows: The adhesive strip reversing fixture for full-screen TVs first inserts the first end of the adhesive strip through the inlet on the second end of the guide groove, pulls the adhesive strip to the application surface position, then holds the handle and aligns it with the desired application position on the inner folded edge of the middle shell, pulling the application body diagonally upwards along the folded edge. The rear silicone strip, under the action of the guide groove and the application surface, is quickly applied to the inner side of the folded edge. This makes application convenient and quick, without spatial limitations, greatly improving work efficiency. Furthermore, the application surface is designed as a curved surface from high to low, which not only provides sufficient space for the adhesive strip, but also gradually flattens the adhesive strip from loose to tight during the application process, ensuring uniform force on the adhesive strip under the pressure of the curved application surface, avoiding the quality hazard of the adhesive strip falling off.

[0017] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations represented in the embodiments below are not limited to those necessary for the solution of the invention described in the claims.

[0027] refer to Figure 1-3 As shown, this specific embodiment provides a reverse-attaching fixture for a full-screen TV, used to attach an adhesive strip 8 to the lower surface of the middle shell folded edge 2. It includes an attachment body 1 placed below the middle shell folded edge 2. The upper surface of the attachment body 1 is provided with a guide groove 3 and an attachment surface 4. The attachment surface 4 is located at a first end in the guide groove 3. The second end of the guide groove 3, opposite to the first end, is provided with an inlet 5 for the adhesive strip 8 to pass through. Specifically, the attachment surface 4 and the inlet 5 are spaced apart to facilitate the adhesive strip 8 to pass through the inlet 5 onto the attachment surface 4. The attachment surface 4 is a curved surface whose height gradually decreases along the direction from the first end to the second end of the guide groove 3. The adhesive strip 8 is inserted through the inlet 5 and placed at the position of the attachment surface 4. The adhesive strip 8 is reverse-attached to the lower surface of the middle shell folded edge 2 by pulling the attachment body 1 obliquely upward.

[0028] It should be noted that the width of the guide groove 3 is greater than the width of the adhesive strip 8 and less than the width of the middle shell fold 2. Specifically, the width of the guide groove 3 is slightly wider than the silicone strip 8 and slightly narrower than the middle shell fold 2. It will not interfere with the adhesive strip during guidance, nor will it exceed the range of the middle shell fold. At the same time, it also plays a limiting role for the adhesive strip, avoiding the problem of the adhesive strip being pasted crookedly.

[0029] like Figure 2 As shown, when applying silicone strips during production, the first end of the silicone strip 8 is inserted into the inlet 5 on the second side of the guide groove 3. The silicone strip 8 is then pulled to the position of the application surface 4. Next, the silicone strip 8 is aligned with the position to be applied on the inner folded edge of the middle shell. The application body 1 is pulled diagonally upward along the folded edge. The silicone strip 8 at the rear end is then quickly applied to the inner side of the folded edge under the action of the guide groove 3 and the application surface 4. The application is convenient, quick, and not limited by space, which greatly improves work efficiency.

[0030] Furthermore, such as Figure 1 As shown, the covering surface 4 includes multiple curved surfaces that form a smooth transition continuous curved surface. The two adjacent curved surfaces are tangentially arranged, and the curvature of each curved surface gradually decreases along the direction from the first end to the second end of the guide groove 3. The covering surface 4 is set as a curved surface with a smooth transition from high to low, which not only leaves enough space for the adhesive strip, but also gradually flattens the adhesive strip from loose to tight during the application process, so that the pressure of the adhesive body 1 on the adhesive strip 8 gradually increases from loose to tight, ensuring that the rate of increase of the pressing force is more uniform. This ensures that the adhesive strip 8 is subjected to more uniform force under the pressure of the curved covering surface 4, and is firmly adhered and not easy to fall off, avoiding the quality risk of the adhesive strip falling off.

[0031] Furthermore, a lubricating film is provided on the bonding surface 4, which can reduce the friction between the adhesive strip 8 and the bonding surface 4, save the operator's labor, and greatly improve the adhesive strip bonding efficiency. Specifically, the lubricating film can be a tough friction reaction film or friction polymerization film formed on-site by the lubricant itself or by the friction chemical reaction between the lubricant and the metal surface. The specific lubricant can be solid or liquid, and can refer to existing technology, as long as it can meet the requirement of reducing friction. This article will not repeat the details.

[0032] This design solves the problem of manually pasting buffer silicone strips onto the lower surface of the middle shell edge, which is not only limited by space and very difficult to do during production, but also results in uneven force on the manually pasted strips, making them prone to falling off.

[0033] In the preferred embodiment of this solution, such as Figure 1As shown, the reverse adhesive fixture also includes a handle 6 for easy pulling and sliding of the adhesive body. The guide groove 3 is located on one side of the upper surface of the adhesive body 1, and the handle 6 is located on the other side of the upper surface of the adhesive body 1. In order to meet the height requirements for convenient operation, a support block 7 is provided between the handle 6 and the adhesive body 1. Specifically, the support block 7 is designed as a cuboid structure, and the height of the support block 7 can be processed and set according to the actual adhesive space to meet the adhesive requirements.

[0034] Meanwhile, in order to simplify the processing technology, the attachment body 1, support block 7 and handle 6 are designed as an integrated structure.

[0035] In a preferred embodiment, the outer surface of the handle 6 is marked with the width specification of the guide groove 3, which allows for quick selection of the reverse-attachment fixture corresponding to the width of the guide groove 3 based on the width of the adhesive strip 8, facilitating management while also providing anti-slip properties.

[0036] Furthermore, the handle 6 is provided with anti-slip parts to increase the friction between the operator's hand and the handle 6, making it easier to pull upwards at an angle. Specifically, the anti-slip parts are made of silicone particles. Of course, the anti-slip parts can also be made of other structures, depending on the situation.

[0037] The adhesive strip mentioned in this embodiment refers to silicone strips in general, and also includes other adhesive components that need to be applied backwards.
