Description

Technical Field

[0001] This utility model belongs to the field of mobile phone component manufacturing technology, and in particular relates to a mobile phone glass cover processing and coating device. Background Technology

[0002] The mobile phone glass cover is a protective transparent component that covers the outermost layer of the mobile phone display screen. Its main functions include protection, touch optimization, and display enhancement. During the CNC machining, transportation, and inspection of the mobile phone glass cover, a protective film needs to be pasted on the surface to prevent scratches and contamination. Therefore, a film coating device is used to coat the mobile phone glass cover.

[0003] A search revealed Chinese Patent Publication No. CN223356041U, which discloses a coating device for finished mobile phone glass covers. The device includes a conveyor table with a protective film roller mounted on it. A pressure roller is fixedly mounted on one side of the protective film roller and a positioning and guiding mechanism on the other side. This mechanism includes two fixed rods symmetrically fixed on both sides of the conveyor table. A first support rod is mounted on the top of each fixed rod, and a positioning guide plate is fixedly mounted at one end of each support rod. This invention, through the positioning and guiding mechanism, can position and guide the mobile phone glass cover. After being positioned on the conveyor table by the two positioning guide plates, the glass cover is conveyed flatly below the protective film roller and pressure roller, preventing the glass cover from tilting and ensuring successful coating, thus improving the quality of the coating process.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Most current coating devices use a roller pressing method to bond the protective film to the mobile phone glass cover during the coating process. This bonding method results in concentrated pressure that is difficult to distribute evenly on the mobile phone glass cover, which can easily lead to air bubbles when air is pushed towards the center. Furthermore, some existing mobile phone glass covers have curved edges, and traditional hard rollers or flat plates cannot achieve perfect bonding, which can easily create wrinkles or unbonded areas at the curved edges, thus affecting the coating effect of the coating device.

[0005] Therefore, this utility model provides a coating device for processing mobile phone glass covers to solve the above problems. Utility Model Content

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0042] In specific implementation, such as Figures 1-6 As shown, this utility model provides a technical solution: a mobile phone glass cover processing and coating device, including a body 1, a coating position 2 is provided on the upper surface of the body 1, the coating position 2 is the position where the mobile phone glass cover and the protective film are bonded; a support plate 3, the lower surface of the support plate 3 is fixedly connected to the upper surface of the body 1, and the support plate 3 is located on the side of the coating position 2; a bonding mechanism 4, the bonding mechanism 4 is provided on the side wall of the support plate 3, and is used to bond the protective film to the mobile phone glass cover; a cleaning mechanism 5, the cleaning mechanism 5 is provided on the side wall of the support plate 3, and is used to clean the dust on the mobile phone glass cover before the protective film is bonded to the mobile phone glass cover; wherein, the bonding mechanism 4 includes a connecting plate 41 and a limiting plate 46, the side wall of the connecting plate 41 is fixedly connected to the side wall of the support plate 3, a fixing plate 42 is fixedly installed on the upper surface of the connecting plate 41, the fixing plate 42 is located above the coating position 2, and a lifting cylinder 43 is fixedly installed on the upper surface of the fixing plate 42.

[0043] One end of the lifting cylinder 43 extends to the lower surface of the fixed plate 42. A mounting plate 44 is fixedly installed on one end of the lifting cylinder 43. A flexible airbag 45 is fixedly installed on the lower surface of the mounting plate 44. The air vent of the flexible airbag 45 extends to the upper surface of the mounting plate 44.

[0044] One end of the limiting plate 46 is fixedly connected to the side wall of the fixing plate 42. A limiting rod 47 is slidably installed on the inner wall of the limiting plate 46. One end of the limiting rod 47 extends to the lower surface of the limiting plate 46 and is fixedly connected to the upper surface of the mounting plate 44.

[0045] An air pump 48 is fixedly installed on the upper surface of the limiting plate 46, and one end of the air supply pipe of the air pump 48 is fixedly connected to one end of the air passage pipe.

[0046] Specifically, by setting up a bonding mechanism 4, downward pressure is applied to the protective film to press it onto the phone's glass cover. The protective film is precisely placed on the phone's glass cover. Then, the lifting cylinder 43 drives the flexible airbag 45 to descend a certain distance via the mounting plate 44. Then, the air pump 48 injects gas into the flexible airbag 45 through the air supply pipe and the air vent pipe. As the gas is injected, the lower surface of the flexible airbag 45 expands into a uniform curved surface. Then, the lifting cylinder 43 continues to drive the flexible airbag 45 to descend via the mounting plate 44. The expanded flexible airbag 45 first contacts the center area of ​​the protective film. Then, the flexible airbag 45 continues to descend. At this time, the contact surface between the flexible airbag 45 and the protective film will expand evenly from the center to the periphery of the protective film, thereby squeezing the protective film from the inside out. This not only achieves bonding between the protective film and the phone's glass cover, but also allows air to be discharged from the center to the edge during the bonding process, effectively avoiding the generation of air bubbles during the bonding process.

[0047] The cleaning mechanism 5 includes a mounting rod 51, an air outlet pipe 56, and a rotating rod 57. The lower surface of the mounting rod 51 is fixedly connected to the other end of the limiting rod 47. A transmission rack 52 is fixedly mounted on the lower surface of the mounting rod 51. A sliding groove is provided on the side wall of the transmission rack 52. A guide rail 53 is slidably mounted on the inner wall of the sliding groove. The side wall of the guide rail 53 is fixedly connected to the side wall of the support plate 3.

[0048] One end of the rotating rod 57 is rotatably connected to the side wall of the support plate 3. A transmission gear 58 is fixedly installed on the outer surface of the rotating rod 57. The transmission gear 58 meshes with the transmission rack 52. A rotating disk 59 is fixedly installed on the other end of the rotating rod 57.

[0049] A connecting rod 510 is rotatably mounted on the side wall of the rotating disk 59 via a rotating shaft. A push rod 511 is rotatably mounted on one end of the connecting rod 510 via the rotating shaft. A piston plate 512 is fixedly mounted on one end of the push rod 511. A limit sleeve 513 is slidably mounted on the outer surface of the push rod 511. One end of the limit sleeve 513 is fixedly connected to the side wall of the support plate 3.

[0050] Both ends of the air outlet pipe 56 are connected to the bellows 54. The side wall of the bellows 54 is fixedly connected to the side wall of the support plate 3. The outer surface of the piston plate 512 is slidably connected to the inner wall of the bellows 54. An air inlet pipe 55 is connected to the other side wall of the bellows 54. A one-way valve and a filter screen are fixedly installed on the inner walls of both the air inlet pipe 55 and the air outlet pipe 56. Several air outlet holes are provided on the side wall of the air outlet pipe 56, and the air outlet holes are aligned with the film coating machine position 2.

[0051] Specifically, a cleaning mechanism 5 is installed to clean dust and other contaminants from the phone's glass cover before the protective film is applied, effectively reducing the risk of contamination before film application. During the descent of the mounting plate 44, the limiting rod 47 moves synchronously under the constraint of the limiting plate 46. The limiting rod 47, through the mounting rod 51, drives the transmission rack 52 to slide under the constraint of the guide rail 53. As the transmission rack 52 displaces, the rotating rod 57 rotates under the action of the transmission gear 58. At this time, the rotating rod 57 drives the rotating disk 59 to rotate synchronously. During the rotation of the rotating disk 59, the connecting rod 5... 10 will drive the push rod 511 to move back and forth under the limit of the limiting sleeve 513. At this time, the push rod 511 drives the piston plate 512 to move back and forth in the air box 54. When the piston plate 512 moves towards the air outlet pipe 56, it will squeeze the gas in the air box 54 into the air outlet pipe 56, and then blow it towards the uncoated mobile phone glass cover through the air outlet hole on the surface of the air outlet pipe 56 to clean the dust on the surface of the mobile phone glass cover. When the push rod 511 drives the piston plate 512 to move towards the rotating disk 59, it will draw air into the air box 54 through the air inlet pipe 55. During the process of drawing air, the filter screen in the air inlet pipe 55 will filter the impurities in the air.

[0052] Working principle: The machine body 1 conveys the mobile phone glass cover to the film coating station 2, and then the robotic arm moves the protective film above the mobile phone glass cover. The protective film is then placed on the mobile phone glass cover, and the bonding mechanism 4 presses down on the protective film to bond it to the mobile phone glass cover. During the downward movement of the bonding mechanism 4, the cleaning mechanism 5 cleans the dust on the mobile phone glass cover.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
