Description

Technical Field

[0001] The utility model relates to the technical field of UV positioning films, in particular to a UV viscosity-reducing positioning film that is easy to remove. Background Art

[0002] UV-resistant positioning film is a special thin film material. UV indicates that the film's viscosity changes through ultraviolet radiation. Its main functions and features include: Initially, it has a certain degree of adhesion, enabling it to position and secure specific objects or components. When the adhesion needs to be released, UV radiation of a specific wavelength and intensity significantly reduces the film's viscosity, allowing the positioned object or component to be removed.

[0003] The UV anti-viscosity positioning film generally still adheres to the outer surface of the object after being irradiated by ultraviolet light after use, but the adhesion between the film and the object is greatly reduced. However, the anti-viscosity glue on the UV anti-viscosity positioning film is bonded to the surface of the object in one piece, and the overall bonding strength is still very high. It is not convenient to remove the positioning film later. In addition, the existing anti-viscosity glue is evenly coated on the surface of the film. When in use, the adhesive layer of the anti-viscosity glue is relatively thick. When removing the anti-viscosity film on the surface of the object, the light needs to pass through the upper film first and then penetrate the anti-viscosity glue, so that the adhesion between the anti-viscosity glue and the surface of the object is reduced. However, some anti-viscosity glues are not well penetrated due to their thickness and are adhered to the surface of the object. When the anti-viscosity glue area adhered to the surface of the object is large, it is difficult to remove the UV anti-viscosity positioning film from the surface of the object. Therefore, the present application proposes a UV anti-viscosity positioning film that is easy to remove. Summary of the Invention

[0004] The purpose of the utility model is to address the problem in the background technology that the viscosity-reducing glue on the UV viscosity-reducing positioning film is all bonded to the surface of the object in one piece, and the overall bonding strength is still very high. When the area of ​​the viscosity-reducing glue bonded to the surface of the object is large, it is difficult to remove the UV viscosity-reducing positioning film from the surface of the object, and it is not convenient to remove the positioning film subsequently. A UV viscosity-reducing positioning film that is easy to remove is proposed.

[0005] The technical solution of the utility model is a UV anti-viscosity positioning film that is easy to remove, comprising a first light-transmitting layer, a second light-transmitting layer bonded to the first light-transmitting layer for removing the positioning film, and a rubber block bonded to the second light-transmitting layer for fixing and positioning the PCB board.

[0006] Optionally, the first light-transmitting layer is provided with circular holes for increasing surface friction.

[0007] Optionally, a triangular groove for separating the first light-transmitting layer and the second light-transmitting layer is provided on the first light-transmitting layer.

[0008] Optionally, a cavity for light transmission is provided on the second light-transmitting layer.

[0009] Optionally, a circular hole for light transmission is opened on the second light-transmitting layer.

[0010] Optionally, the second light-transmitting layer is provided with triangular grooves for light transmission.

[0011] Optionally, the adhesive blocks are arranged at equal intervals and bonded to the bottom of the second light-transmitting layer, and the horizontal spacing between the two second light-transmitting layers is larger, and the vertical spacing is smaller.

[0012] Optionally, the adhesive block is bonded to the anti-adhesive layer, and a triangular protruding block is provided on the anti-adhesive layer, and the triangular protruding block is matched with the triangular groove on the second light-transmitting layer.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] The utility model utilizes the first light-transmitting layer and the second light-transmitting layer to be bonded together through an adhesive layer, so that the two can be quickly separated, and the thickness after separation is reduced, thereby improving the light penetration effect of the light-transmitting layer.

[0015] Furthermore, the adhesive coating on the other side of the second light-transmitting layer is used to adhere to the glue block and clean the glue block remaining on the PCB board, thereby avoiding the glue block from remaining and improving the cleaning effect of the PCB board.

[0026] Example 1

[0027] like Figure 1 As shown, the utility model proposes a UV anti-viscosity positioning film that is easy to remove, including a first light-transmitting layer 1, on which is bonded a second light-transmitting layer 2 for removing the positioning film, the first light-transmitting layer 1 and the second light-transmitting layer 2 are both made of transparent films, and a layer of glue for bonding is applied between the first light-transmitting layer 1 and the second light-transmitting layer 2, and the second light-transmitting layer 2 is bonded with a glue block 3 for fixing and positioning the PCB board 4, and the glue block 3 is made of UV anti-viscosity glue.

[0028] like Figure 2As shown, an upper circular hole is provided on the first light-transmitting layer 1 to increase surface friction. The provision of the upper circular hole helps to remove the first light-transmitting layer 1 from the second light-transmitting layer 2 .

[0029] like Figure 1-3 As shown, an upper triangular groove is provided on the first light-transmitting layer 1 for separating the first light-transmitting layer 1 and the second light-transmitting layer 2. The opening of the upper triangular groove can increase the friction force while creating a gap at the edge where the first light-transmitting layer 1 and the second light-transmitting layer 2 are connected, thereby facilitating the separation of the first light-transmitting layer 1 and the second light-transmitting layer 2.

[0030] like Figure 2 As shown, a cavity for light transmission is provided on the second light-transmitting layer 2. The provision of the cavity helps light to penetrate and facilitates the subsequent pinching of the second light-transmitting layer 2 from the surface.

[0031] like Figure 2 As shown, a lower circular hole for light transmission is provided on the second light-transmitting layer 2 . The opening of the lower circular hole helps the penetration of ultraviolet light, thereby increasing the penetration effect of the glue block 3 .

[0032] like Figure 1-3 As shown, the second light-transmitting layer 2 is provided with a lower triangular groove for light transmission, and the lower triangular groove is provided to facilitate the penetration of ultraviolet light.

[0033] like Figure 2 As shown, the glue blocks 3 are arranged at equal distances and bonded to the bottom of the second light-transmitting layer 2. The horizontal spacing between the two second light-transmitting layers 2 is larger, and the vertical spacing is smaller, so that each glue block 3 is a small whole, reducing the connection between them, thereby preventing the glue blocks 3 from being connected to each other.

[0034] like Figure 3 As shown, the adhesive block 3 is bonded to the anti-sticking layer 5, and a triangular protruding block is provided on the anti-sticking layer 5. The triangular protruding block fits on the lower triangular groove on the second light-transmitting layer 2, thereby effectively reducing dust from entering the gap in the lower triangular groove.

[0035] In this embodiment, the first light-transmitting layer 1, the second light-transmitting layer 2 and the adhesive block 3 of the positioning film are first removed from the anti-adhesive layer 5, and then the first light-transmitting layer 1 is placed horizontally on the table so that the adhesive block 3 is on the top for bonding the PCB board 4, and then the PCB board 4 is bonded to the adhesive block 3, and then the excess first light-transmitting layer 1 and the second light-transmitting layer 2 are cut off with a blade. When the PCB board 4 is made and the adhesive block 3 needs to be removed, the first light-transmitting layer 1 is first removed from the second light-transmitting layer 2, and then the second light-transmitting layer 2, the adhesive block 3 and the PCB board 4 are passed through the adhesive block 3. After a pass of ultraviolet light, the adhesion between the adhesive block 3, the PCB board 4 and the second light-transmitting layer 2 will be reduced under the irradiation of the ultraviolet light. At this time, by tearing off the second light-transmitting layer 2, part of the adhesive block 3 will be taken away from the PCB board 4 by the second light-transmitting layer 2, and part of the adhesive block 3 will be adhered to the PCB board 4. At this time, turn the second light-transmitting layer 2 over and gently press the other sticky side on the remaining adhesive block 3. This can clean some of the adhesive blocks 3 remaining on the PCB board 4, thereby facilitating the removal of the positioning film.

[0036] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
