Description

Technical Field

[0001] The utility model relates to the field of glue transfer, in particular to a glue transfer device for a light-collecting camera. Background Art

[0002] As the pixels of mobile phone cameras increase, the focusing function requirements are getting higher and higher, and the light refraction inside the camera needs to be lower and lower. The inner wall of the camera will be coated with glue or bonded with a glue layer to reduce the light refraction of the camera.

[0003] The glue layer on the inner wall of the existing focusing camera can be directly applied to the inner wall of the camera and then cured by light irradiation, or the glue can be pre-cured and then cut into a certain size, and then the cut glue layer is transferred to the inner wall of the camera. Existing glue transfer devices, such as the glue curing device for transfer film production proposed in patent application number "CN202123260637.9", use structures such as a heating box, an ultraviolet lamp, a cooling box, and a cooling tube. The ultraviolet lamp increases the bonding strength between the glue and the transfer film, and cools the transfer film, thereby prompting the glue to cure on the surface of the transfer film, which helps to improve the curing effect of the glue and accelerate the curing efficiency of the glue.

[0004] However, the existing glue transfer device still has defects. The surface of the transferred glue layer is flat. When it is bonded to the inner wall of the camera, the refractive index is high, and the focusing performance of the camera is poor. The coating made of low-refractive glue is expensive. Therefore, a glue transfer device for a focusing camera is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] A glue transfer device for a focusing camera, such as Figures 1-6 As shown, it includes a base 1, a cover body 3 is clamped on the upper end of the base 1, and the cover body 3 can be disassembled and assembled with the base 1. A column 2 is fixed between the base 1 and the cover body 3 by bolts. The side wall of the column 2 is rotatably connected to a rotating seat 4, and the side wall of the rotating seat 4 is fixed with a PC diaphragm 5 and a carbon black diaphragm 7. The side wall of the rotating seat 4 is slidably connected with a PET diaphragm 8 for docking with the PC diaphragm 5 or the carbon black diaphragm 7. A driving member for driving the rotating seat 4 to rotate and an electric slide 9 structure for driving the PET diaphragm 8 to slide up and down are provided inside the column 2. The rotation of the rotating seat 4 and the sliding of the PET diaphragm 8 are electrically controlled. The PET diaphragm 8 and the PC diaphragm 5 are transparent. A convex pattern 6 is provided on the upper surface of the PC diaphragm 5. A laser laser scheme is used to engrave a pyramid convex texture on the surface of the PC diaphragm 5. Two groups of brush roller assemblies for applying glue to the convex pattern 6 and the PET diaphragm 8 are fixed to the side of the cover body 3 away from the column 2. A UV lamp 23 for irradiating and curing the glue is fixed to the inner wall of the cover body 3.

[0026] During operation, the PC film 5 is located below the PET film 8. The surface of the PC film 5 is provided with a coating to prevent glue from adhering to the PC film 5. A set of brush roller assemblies is used to apply UV glue to the convex patterns 6 on the PC film 5. The PET film 8 is controlled to connect with the PC film 5. After UV light curing, the PET film 8 is separated from the PC film 5 with the cured UV glue layer. The surface of the cured UV glue layer has convex patterns 6. The rotating seat 4 is controlled to rotate, and the carbon black film 7 is rotated to Below the PET film 8, another set of brush roller assemblies applies UV black transfer glue to the surface of the cured UV glue layer to control the docking of the PET film 8 and the carbon black film 7. After UV light irradiation and curing, a black glue film layer with convex patterns 6 is formed between the UV cured glue layer and the carbon black film 7. The black convex pattern 6 glue film layer is cut and bonded to the inner wall of the camera. The relatively smooth and flat glue layer can effectively reduce the refractive index of light and improve the focusing performance of the camera. Compared with the use of low-refractive glue, the cost is low and does not rely on imports.

[0027] like Figure 5-Figure 6 As shown, the convex pattern 6 is composed of multiple groups of quadrangular pyramids, which are arranged in a rectangular array, and the angle between the PC film 5 and the carbon black film 7 is set to be a right angle.

[0028] The quadrangular pyramid-shaped convex pattern 6 is similar to a pyramid, so that the surface of the transferred film has a convex pattern, which is bonded to the inner wall of the camera to increase the light absorption effect and reduce the light refractive index. The rotating seat 4 rotates 90 degrees to control the position conversion between the PC film 5 and the carbon black film 7 under the PET film 8.

[0029] like Figure 1 、 Figure 3 、 Figure 4 As shown, the brush roller assembly includes an electric slide 9, two groups of electric slides 9 are fixed to the inner wall of the cover 3 on the side away from the column 2, and the two groups of electric slides 9 are slidably connected to a moving seat 10. One side of the two groups of moving seats 10 is fixed with a servo motor 12, and the output end of the two groups of servo motors 12 is fixed with a roller body 13. The two groups of roller bodies 13 apply glue to the convex pattern 6 and the PET film 8 respectively.

[0030] The electric slide 9 (model TOYO-GTH8) controls the sliding of the movable seat 10, thereby controlling the sliding of the roller body 13. At the same time, the servo motor 12 (model 110ST-M05030) controls the rotation of the roller body 13, so that the moving roller body 13 rotates to apply glue to the convex pattern 6 on the PC diaphragm 5 and the carbon black diaphragm 7.

[0031] like Figure 3As shown, one side of the two groups of movable seats 10 is fixed with a glue chamber 11 for gluing the roller body 13, and the inside of the two groups of glue chambers 11 are filled with UV glue. A through-hole 18 is opened through the upper end of the cover body 3, and a partition 19 for dividing the space of the cover body 3 is inserted into the through-hole 18.

[0032] Different glues are added inside the glue chamber 11. The glue enters the roller body 13 through the pipe and the negative pressure device and overflows from the surface of the roller body 13. This belongs to the existing technology and will not be described in detail. When the two groups of roller bodies 13 are located at one end of the cover body 3 at the same time, the two groups of roller bodies 13 are staggered. The partition 19 can separate the roller body 13 and the PET film 8 to prevent the light emitted by the UV lamp 23 from solidifying the residual glue on the surface of the roller body 13. When the roller body 13 is running, the partition 19 can be pulled out.

[0033] like Figures 1-4 As shown, a fixing seat 14 is fixedly connected to one side of the cover body 3, and two groups of servo motors 15 are fixedly connected to one end of the fixing seat 14. The output ends of the two groups of servo motors 15 are fixedly connected to reciprocating screws 16. The two groups of reciprocating screws 16 are respectively rotatably connected to the two groups of fixing seats 14. The side walls of the two groups of reciprocating screws 16 are threadedly connected with rings 17. The two groups of rings 17 are respectively connected to the two groups of rollers 13 in a sleeve-type sliding connection, and one end of the two groups of rings 17 is connected to the side wall of the cover body 3 in a sliding manner.

[0034] When the roller 13 is coated, the servo motor 15 controls the reciprocating screw 16 to rotate, causing the ring 17 to slide, and the residual glue on the surface of the roller 13 can be scraped off to facilitate the next coating.

[0035] like Figure 1-Figure 2 As shown, a collecting groove 22 is inserted into the cover body 3 below the ring 17 , and a back plate 20 is clamped on the back of the cover body 3 .

[0036] The collecting groove 22 collects the residual glue scraped off by the ring 17, and the back plate 20 seals one side of the cover body 3 to prevent dust in the air from affecting the transfer effect.

[0037] The working principle of the glue transfer device for a focusing camera provided by the utility model is as follows:

[0038] UV glue is applied to the convex pattern 6 on the PC diaphragm 5 by a group of brush roller assemblies, and the PET diaphragm 8 is controlled to be docked with the PC diaphragm 5. After UV light irradiation and curing, the PET diaphragm 8 is separated from the PC diaphragm 5 with the cured UV glue layer. The surface of the cured UV glue layer has convex patterns 6. The rotating seat 4 is controlled to rotate, and the carbon black diaphragm 7 is rotated to the bottom of the PET diaphragm 8. Another group of brush roller assemblies is applied to the surface of the cured UV glue layer with UV black transfer glue, and the PET diaphragm 8 is controlled to be docked with the carbon black diaphragm 7. After UV light irradiation and curing, a black glue diaphragm layer with convex patterns 6 is formed between the UV cured glue layer and the carbon black diaphragm 7. The black convex pattern 6 glue diaphragm layer is cut and bonded to the inner wall of the camera. The relatively smooth and flat glue layer can effectively reduce the refractive index of light and improve the focusing performance of the camera. Compared with the use of low-refractive glue, the cost is low and does not rely on imports.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
