DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] like Figures 1 to 5 As shown: This embodiment discloses an irregular spherical film laminating device: comprising a frame 1, a hot air generating device 2 connected to the frame 1, and a carrier assembly. The carrier assembly includes a hollow pressure cover 4, a carrier sleeve 5, and a carrier 6 slidably connected to the interior of the carrier sleeve 5. A sealing device is provided between the carrier sleeve 5 and the carrier 6, and the carrier sleeve 5 is connected to a vacuum device. The carrier 6 is provided with a product positioning device for fixing the product. The middle of the hollow pressure cover 4 is a hollow structure. This hollow structure facilitates the placement of the product into the carrier 6 and can ensure the smooth passage of the air outlet assembly 3. The function of the hollow pressure cover 4 is to press the film onto the end of the carrier sleeve 5.

[0033] An air outlet assembly 3 is provided at the air outlet end of the hot air generating device 2 . The product-facing surface of the air outlet assembly 3 matches the contour of the product and is provided with a plurality of air holes 322 .

[0034] Combine Figure 2 and Figure 3 The air outlet assembly 3 includes an upper cover 31 and an air outlet nozzle 32 connected to the upper cover 31. The upper cover 31 has a conical cavity 311, and the air outlet nozzle 32 has a conical protrusion 321 that matches the conical cavity 311. The air holes 322 are arranged on the side of the conical protrusion 321. This forms a conical channel between the conical cavity 311 and the conical protrusion 321. This conical channel acts as a guide and is connected to the air holes 322, which helps to expand the hot air's effective area and evenly heat the protective film.

[0035] The hollow gland 4 is connected to the frame 1 through at least two gland cylinders 41 . The gland cylinders 41 are used to drive the hollow gland 4 to move relative to the carrier sleeve 5 .

[0036] The specific structure of the sealing device between the carrier sleeve 5 and the carrier 6 is as follows: a ring groove 61 is provided on the side of the carrier 6, and a sealing ring 9 is provided in the ring groove 61. The carrier sleeve 5 is connected to the vacuum device through an air pipe 51, and the air pipe 51 is also provided with a valve.

[0037] Combine Figure 4 and Figure 5 The specific structure of the relative sliding between the carrier sleeve 5 and the carrier 6 is as follows: a screw is provided at the bottom of the carrier 6, which is used to drive the carrier 6 to slide up and down along the carrier sleeve 5. The screw is driven by a motor 7 mounted on the frame 1. Furthermore, a guide post 8 is provided between the carrier 6 and the frame 1. The guide post 8 can be fixedly mounted on the frame 1, and a matching guide sleeve is mounted on the carrier 6.

[0038] The frame 1 of this embodiment includes a workbench 12 and a rear vertical plate 11 and a side vertical plate 13 connected to the workbench 12 . The hot air generating device 2 is connected to the rear vertical plate 11 , the hollow pressure cover 4 is connected to the side vertical plate 13 , and the carrier assembly is connected to the workbench 12 .

[0039] This embodiment also discloses a method for applying a film to an irregular spherical surface. The method specifically follows the steps below:

[0040] The product to be coated is placed in the carrier 6 and secured. The specific structure and principle of the carrier 6 for securing the product are prior art and will not be described in detail in this embodiment. The protective film is then placed in the carrier sleeve 5 and pressed tightly by the hollow pressure cover 4. It should be noted that the protective film used in this embodiment also includes a carrier film, which is attached to the protective film. After the coating is completed, the carrier film needs to be removed.

[0041] The protective film is heated and softened by hot air generated by the hot air generator 2. During the heating and softening process, the parameters of the hot air must be strictly controlled to ensure uniform heating of the protective film while preventing overheating and damage. The parameters of the hot air generated by the hot air generator 2 include the hot air temperature, hot air duration, and hot air speed.

[0042] When the protective film softens to a predetermined state, the air between carrier sleeve 5 and carrier 6 is extracted. Under the influence of atmospheric pressure, the protective film adheres tightly to the surface of the product. Because the protective film is in a stretched state, wrinkles are prevented. During this process, as the protective film is pressed against the product surface by the external atmospheric pressure, it assumes a roughly spherical shape with its opening facing upward. Therefore, the film is positioned lower near the center, contacting the product first. This allows the film application process to spread from the center of the product outward, facilitating the removal of air bubbles.

[0043] The motor 7 then rotates and drives the carrier 6 upward, allowing the air outlet assembly 3 to conform to the product's contours and maintaining the preset heating time to further heat and soften the protective film. The carrier 6 is then operated to separate the air outlet assembly 3 from the protective film, and the carrier film is removed to complete the film application process.

[0044] Compared with the prior art, this embodiment adheres the protective film to the product surface by heating the protective film, vacuuming it, and hot pressing the air outlet component 3, thereby ensuring the quality of the film and ensuring that the protective film has no wrinkles or bubbles.

[0045] Under the action of atmospheric pressure, the protective film is stretched, and the middle area contacts the product first, ensuring that the film application process is carried out from the inside to the outside, which helps to eliminate bubbles. The protective film is in a stretched state during the contact with the product, which helps to eliminate wrinkles.

[0046] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
