Description

Technical Field

[0001] This application relates to the field of curved surface lamination technology, and in particular to a curved surface lamination machine. Background Technology

[0002] In related technologies, curved glass, due to its curvature, places higher demands on the lamination technology. The lamination process involves tightly attaching a thin film to the glass surface, avoiding defects such as air bubbles during the process. Currently, a common lamination technique involves placing the film and curved glass in upper and lower molds respectively. After removing the protective film, the upper and lower molds are precisely positioned, and appropriate pressure is applied to achieve a tight bond between the film and the curved glass. However, throughout the entire curved glass lamination process, the molds remain rigid, affecting the lamination accuracy and quality between the curved glass and the film. Furthermore, this can easily lead to breakage of the curved glass and cause air bubbles to form during the lamination process. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a curved surface laminating machine that can tightly adhere a protective film to the curved surface of a product while minimizing air bubbles.

[0004] The curved surface laminating machine according to an embodiment of the present invention includes: a laminating mechanism, a feeding mechanism, a conveying mechanism, and a waste removal mechanism. The laminating mechanism includes a mounting frame, a first driving member, and a flexible member. The first driving member is disposed on the mounting frame, and its output end is connected to the flexible member and used to drive the flexible member to rise and fall, so that the flexible member can deform and press against the upper surface of the product. The feeding mechanism is disposed on the mounting frame and includes a feeding roller and a waste collection roller. The feeding roller is used to provide a protective film to the underside of the flexible member, and the waste collection roller is used to roll up waste material. The conveying mechanism is used to convey the product to the underside of the laminating mechanism. The waste removal mechanism is disposed on one side of the laminating mechanism and is used to cut off the edge of the protective film covered on the product.

[0005] The curved surface laminating machine according to the embodiments of this utility model has at least the following beneficial effects: This curved surface laminating machine includes a laminating mechanism, a feeding mechanism, a conveying mechanism, and a waste removal mechanism. In use, the feeding mechanism first conveys the product to the area below the laminating mechanism. Then, the first driving member in the laminating mechanism drives the flexible member downward and presses the protective film in the feeding mechanism down to cover the product. Since the flexible member can deform during the process of continuing to press down after contacting the product, the protective film can be completely and tightly adhered to the product, reducing the possibility of air bubbles being generated during the laminating process. Subsequently, the flexible member moves upward under the drive of the first driving member, and the waste removal mechanism cuts off the outer edge of the protective film covering the product, thereby achieving the application of a protective film corresponding to the size of the product. Therefore, the curved surface laminating machine of this application has the technical effect of tightly adhering the protective film to the curved surface of the product with fewer air bubbles.

[0006] According to some embodiments of the present invention, the waste discharge mechanism includes a heating wire, which is used to melt and cut the edge of the protective film on the product.

[0007] According to some embodiments of the present invention, the waste discharge mechanism includes a second driving member and a third driving member.

The output end of the third driving member is connected to a heating wire and is used to drive the heating wire to move up and down.

[0008] According to some embodiments of the present invention, the feeding mechanism includes a fourth driving member and a material carrier fixture. The material carrier fixture is used to carry the product. The output end of the fourth driving member is connected to the material carrier fixture and is used to drive the material carrier fixture to enter or leave below the flexible member.

[0009] According to some embodiments of this utility model, the upper surface of the material carrier fixture is a first curved surface that is low in the middle and high at both ends, and the bottom surface of the flexible part is a second curved surface that is convex in the middle. The curvature of the second curved surface is greater than that of the first curved surface.

[0010] According to some embodiments of this utility model, the upper end face of the material-carrying fixture is provided with a negative pressure hole for connecting to an external negative pressure generating device.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0022] The following is for reference. Figures 1 to 5 This invention describes a curved surface coating machine according to an embodiment of the present invention.

[0023] like Figures 1 to 2 As shown, the curved surface laminating machine according to an embodiment of the present invention includes: a laminating mechanism 100, a feeding mechanism 200, a conveying mechanism 300, and a waste removal mechanism 400. The laminating mechanism 100 includes a mounting frame 110, a first driving member 120, and a flexible member 130. The first driving member 120 is disposed on the mounting frame 110, and its output end is connected to the flexible member 130 and is used to drive the flexible member 130 to rise and fall, so that the flexible member 130 can deform and press against the upper surface of the product. The feeding mechanism 200 is disposed on the mounting frame 110 and includes a feeding roller 210 and a waste collection roller 220. The feeding roller 210 is used to provide a protective film 230 to the lower part of the flexible member 130, and the waste collection roller 220 is used to roll up the waste material. The conveying mechanism 300 is used to convey the product to the lower part of the laminating mechanism 100. The waste removal mechanism 400 is disposed on one side of the laminating mechanism 100 and is used to cut the edge of the protective film 230 covered on the product.

[0024] It is understood that this curved surface laminating machine includes a laminating mechanism 100, a feeding mechanism 200, a conveying mechanism 300, and a waste removal mechanism 400. In use, the conveying mechanism 300 first transports the product to the underside of the laminating mechanism 100. Then, the first driving member 120 in the laminating mechanism 100 drives the flexible member 130 downward, pressing the protective film 230 from the feeding mechanism 200 onto the product. Since the flexible member 130 can deform during the downward pressing process after contacting the product, the protective film 230 can be completely and tightly adhered to the product, reducing the possibility of air bubbles during the laminating process. Subsequently, the flexible member 130 moves upward under the drive of the first driving member 120, and the waste removal mechanism 400 cuts off the outer edge of the protective film 230 covering the product, thereby achieving the application of a protective film 230 of the corresponding product size. Therefore, the curved surface laminating machine of this application can tightly adhere the protective film 230 to the curved surface of the product and has the technical effect of fewer air bubbles.

[0025] The feeding mechanism 200 includes a feeding roller 210 for unwinding the protective film 230 and a waste collection roller 220 for winding up the waste. The flexible member 130 is located above the feeding roller 210 and the waste collection roller 220 to press the protective film 230 released by the feeding roller 210. After laminating a product, the waste discharge mechanism 400 cuts off the outer edge of the protective film 230 that exceeds the edge of the product. The waste collection roller 220 then winds up the waste, and the feeding roller 210 rewinds a new protective film 230 for laminating the next product.

[0026] Specifically, the flexible component can be made of flexible materials such as airbags, silicone components, and rubber components, as long as it can be flexibly pressed onto the product.

[0027] Understandably, the waste removal mechanism 400 includes a heating wire 410, which is used to cut the edge of the protective film 230 on the product. For example, as Figures 1 to 3 As shown, in this embodiment, the outer edge of the protective film 230 that extends beyond the edge of the product can be cut off by heating it with the heating wire 410, thereby making the protective film 230 on the product fit the size of the product.

[0028] It should be understood that in other embodiments, the waste discharge mechanism 400 may also be an infrared heating wire 410, which directly cuts the protective film 230 by radiating infrared rays.

[0029] It is understood that the waste discharge mechanism 400 includes a second driving member 420 and a third driving member 430. The output end of the second driving member 420 is connected to the heating wire 410 and is used to drive the heating wire 410 closer to or further away from the flexible member 130. The output end of the third driving member 430 is connected to the heating wire 410 and is used to drive the heating wire 410 up and down. For example, as Figures 1 to 3 As shown, in this embodiment, the waste discharge mechanism 400 includes a second driving member 420 for driving the heating wire 410 to approach or move away from the lower part of the flexible member 130, and a third driving member 430 for driving the heating wire 410 to move up and down. Therefore, in use, after the flexible member 130 presses the protective film 230 onto the product and moves upward away from the protective film 230, the second driving member 420 drives the heating wire 410 to approach the upper part of the protective film 230, and then the third driving member 430 drives the heating wire 410 downward, thereby melting the outer edge of the protective film 230 exposed at the edge of the product.

[0030] It is understood that the feeding mechanism 300 includes a fourth drive member 310 and a material carrier 320. The material carrier 320 is used to carry the product. The output end of the fourth drive member 310 is connected to the material carrier 320 and is used to drive the material carrier 320 into or out of the flexible member 130. For example, as Figures 1 to 2As shown, in this embodiment, the product after melting is supported by the material carrier 320 and moves away from below the flexible member 130 under the drive of the fourth drive member 310, so that the coating process in the above steps can be repeated after a new product to be coated is replaced.

[0031] It is understandable that the upper surface of the material carrier fixture 320 is a first curved surface that is low in the middle and high at both ends, and the bottom surface of the flexible component 130 is a second curved surface that convexes downward in the middle. The curvature of the second curved surface is greater than that of the first curved surface. For example, as... Figures 1 to 2 As shown, in this embodiment, the curvature of the convex flexible member 130 is greater than the curvature of the concave upper surface of the material carrier fixture 320. Therefore, when the flexible member 130 first contacts the product, it can reach the lowest point of the product through the protective film 230. As the downward pressure continues, the flexible member 130 deforms and gradually covers the upper surface of the product. This allows the air bubbles between the product and the protective film 230 to be gradually squeezed out from the lowest point of the concave surface of the product, thereby improving the tightness of the fit.

[0032] It should be understood that in other embodiments, the material carrier fixture may also be a convex surface that is high in the middle and low at both ends, so that the product being carried may also be high in the middle and low at both ends, and the flexible component may also be able to flexibly coat the convex product.

[0033] Understandably, the upper end face of the material carrier 320 is provided with a negative pressure hole for connecting to an external negative pressure generating device. For example, in this embodiment, the upper end face of the material carrier 320 is provided with a negative pressure hole, which can tightly adsorb and position the product, preventing the product from shifting and thus affecting the coating effect.

[0034] Understandably, it also includes a heat source supply mechanism 500, which includes a heat source 510 for heating the protective film 230 beneath the flexible member 130. For example, as... Figure 4 As shown, in this embodiment, the protective film 230 is heated by the heat source 510 in the heat source supply mechanism 500, so that the protective film 230 softens and can be more pliably bonded to the product under the pressure of the flexible part 130, resulting in a better bonding effect.

[0035] It is understandable that the heat source 510 is a fan or an infrared heating plate. For example, such as Figure 4 As shown, in this embodiment, the heat source 510 can be a fan that blows hot air, or an infrared heating plate that heats the protective film 230 with infrared rays.

[0036] It is understood that the heat source supply mechanism 500 also includes a fifth driving element 520, the output end of which is connected to the heat source 510 and used to drive the heat source 510 closer to or further away from the flexible element 130. For example, as Figure 4 As shown, in this embodiment, before the flexible component 130 presses down on the protective film 230, the fifth driving component 520 drives the heat source 510 close to the protective film 230 to heat the protective film 230. Then, the fifth driving component 520 drives the heat source 510 away from the protective film 230, and the flexible component 130 then presses down on the protective film 230 to cover the product, thereby achieving film coating on the product. During film coating, the heat source 510 is kept away from the flexible component 130, thus preventing high temperatures from causing aging of the flexible component 130.

[0037] Understandably, it also includes a housing 700 and an air filter 600. The housing is located outside the film-coating mechanism 100, the feeding mechanism 200, and the waste discharge mechanism 400. The air filter 600 is located within the housing and is used to filter the air inside the housing. For example, as... Figures 1 to 5 As shown, in this embodiment, the air filter 600 is located on the top of the housing and is used to filter the air inside the housing to filter particles generated by the melting of the protective film by the heating wire.

[0038] Specifically, the top of the housing 700 is provided with an exhaust port 710 to exhaust the waste gas generated by the heating wire.

[0039] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
