Description

Technical Field

[0001] The utility model belongs to the technical field of camera lens assembly, in particular to a device for automatically gluing camera lens assembly. Background Art

[0002] The camera lens is an important component of the camera. Its main function is to collect and focus light, project the light onto the camera's sensor or film through the camera lens, and thus form an image.

[0003] CN202320248972.7 discloses a precision gluing device for optical lens assembly, including a base, an outer rod and a positioning rotary using an alignment light ring. When gluing the optical lens assembly, the optical lens assembly can be clamped and fixed by a starting chuck. When injecting glue, the second valve is opened and the first valve is closed. The piston moves downward under the drive of the servo electric cylinder, squeezing out the glue inside the glue injection tube, and flows out from the glue injection head to the gluing position of the optical lens assembly to complete the gluing operation. Before starting the servo electric cylinder, the staff can turn on the lamp bead. The lamp bead generates light that passes through the lens of the ring to generate a halo that is projected onto the surface of the optical lens assembly. The staff can turn the second handle screw to pull the sleeve ring left and right to adjust the alignment position, so that the gluing alignment work can be completed clearly, intuitively and accurately through the halo alignment position, which greatly facilitates the staff to locate the gluing position and improves the convenience of use.

[0004] In the above technical solution, the optical lens assembly is clamped and fixed by a chuck, and then the optical lens assembly is driven to rotate under the drive of the positioning turntable, and then the glue is applied to the position of the optical lens assembly by the glue injection head. Since the inner wall of the lens is circular and the glue dispensing head is in a vertical position, when dispensing glue on the inner wall of the lens, the glue may not be able to flow smoothly to the edge of the inner wall, resulting in some areas failing to contact the glue, affecting the bonding effect of the lens.

DETAILED DESCRIPTION

[0026] The following will be combined with the 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.

[0027] Example 1

[0028] refer to Figures 1 to 3A device for automatically gluing camera lens assembly includes a workbench 1 and a glue dispensing mechanism 2 located above the workbench 1. The workbench 1 is provided with a vertical lifting mechanism 11 and a rotating mechanism 12. The glue dispensing mechanism 2 is connected to the vertical lifting mechanism 11. The rotating mechanism 12 is provided with a clamping mechanism 121 for fixing the camera lens. The glue dispensing mechanism 2 includes a glue dispensing needle 21. The bottom end of the glue dispensing needle 21 is provided with a bending portion 211.

[0029] The vertical lifting mechanism 11 is used to drive the dispensing needle 21 downward so that the bent portion 211 enters the camera lens;

[0030] The rotating mechanism 12 is used to drive the clamping mechanism 121 to rotate, so that the bent portion 211 can dispense glue along the circumference of the inner wall of the camera lens.

[0031] Under this design, the worker first places the camera lens in the clamping mechanism 121 and then uses the clamping mechanism 121 to clamp and fix the camera lens, and then drives the dispensing mechanism 2 downward through the vertical lifting mechanism 11 so that the bent portion 211 of the dispensing needle 21 enters the inner wall of the camera lens. Since the dispensing needle 21 has a bent portion 211, the output port of the dispensing needle 21 will face the inner wall of the camera lens, and then the rotation mechanism 12 drives the rotation of the clamping mechanism 121 to rotate so that the camera lens rotates, and then the dispensing needle 21 performs circumferential dispensing of glue on the inner wall of the camera lens. After the dispensing is completed, the rotating mechanism 12 stops, the rotating mechanism 12 releases the camera lens, and the vertical lifting mechanism 11 resets; in this way, when the dispensing needle 21 dispenses glue on the inner wall of the camera lens, the glue sprayed by the dispensing needle 21 can more accurately cover the target area of ​​the inner wall of the camera lens, thereby improving the effect of the lens being bonded to the camera lens.

[0032] Preferably, the dispensing needle 21 is detachably connected to the dispensing mechanism 2. Camera lenses have different sizes. When dispensing glue for camera lenses of different sizes, workers can replace the dispensing needle 21 so that the glue sprayed from the bent portion 211 can better cover the inner wall of the camera lens.

[0033] In this embodiment, the angle between the bending portion 211 and the rotation axis of the rotating mechanism 12 is 30° to 45°. In a preferred embodiment, the angle between the bending portion 211 and the rotation axis of the rotating mechanism 12 can be 30°; in other embodiments, the angle between the bending portion 211 and the rotation axis of the rotating mechanism 12 can be 45°, which makes it easier for staff to observe the dispensing of glue on the bending portion;

[0034] Moreover, some camera lenses are relatively narrow in size, and glue needs to be dispensed deeper into the camera lens. In this case, the smaller the angle between the bending portion 211 and the rotation axis of the rotating mechanism 12, the deeper the bending portion 211 can enter the camera lens to dispense glue.

[0035] More preferably, the number of the clamping mechanisms 121 and the number of the rotating mechanisms 12 are both two, and they correspond one to one;

[0036] Preferably, the workbench 1 is further provided with a horizontal driving mechanism 13 for driving the vertical lifting mechanism 11 to move horizontally, and the vertical lifting mechanism 11 is connected to the horizontal driving mechanism 13 .

[0037] Specifically, the workers place the two camera lenses into the two clamping mechanisms 121 respectively, and let the clamping mechanisms 121 clamp and fix them. Then the horizontal driving mechanism 13 first drives the vertical lifting mechanism 11 to move above the first clamping mechanism 121, and then the vertical lifting mechanism 11 drives the dispensing needle 21 downward to dispense glue on the first camera lens. After the dispensing of the first camera lens is completed, the vertical lifting mechanism 11 is reset, and the horizontal driving mechanism 13 drives the vertical lifting mechanism 11 to move above the next camera lens. The vertical lifting mechanism 11 drives the dispensing needle 21 downward to dispense glue on the camera lens. After the dispensing is completed, the vertical lifting mechanism 11 is reset, the horizontal driving mechanism 13 is reset, and the clamping mechanism 121 releases the fixation of the camera lens. Finally, the worker can take out the camera lens.

[0038] Preferably, the rotating mechanism 12 includes a mounting frame 122 provided at the bottom of the workbench 1, and a rotating motor 123 provided at the bottom of the mounting frame 122. The workbench 1 is provided with a first through hole, and the output end of the rotating motor 123 passes through the first through hole and is connected to the clamping mechanism 121.

[0039] It also includes a coupling 3 and a connecting shaft 4 . The connecting shaft 4 is connected to the bottom of the clamping mechanism 121 . The coupling 3 is connected between the connecting shaft 4 and the power output end of the rotating motor 123 .

[0040] Specifically, the rotating motor 123 is installed at the bottom of the mounting frame 122, and the connecting shaft 4 is connected to the bottom of the clamping mechanism 121. When the rotating motor 123 is working, it can be transmitted to the clamping mechanism 121 through the coupling 3, and the output end of the rotating motor 123 is connected to the clamping mechanism 121 through the first through hole, so that the clamping mechanism 121 will not contact with the workbench 1, reducing the friction generated by the clamping mechanism 121 with the workbench 1 during the rotation process, so that the rotating motor 123 can drive the clamping mechanism 121 to rotate more smoothly.

[0041] More preferably, the glue dispensing mechanism 2 further includes a fixing frame 22 disposed on the vertical lifting mechanism 11, a glue bottle 23 is disposed on the fixing frame 22, and a glue dispensing needle 21 is disposed at the bottom of the glue bottle 23. The glue bottle 23 is used to store glue, and the glue in the glue bottle 23 is discharged through the glue dispensing needle 21 so that the glue can be sprayed on the inner wall of the camera lens.

[0042] Preferably, the clamping mechanism 121 is a three-jaw chuck, a four-jaw chuck, or a six-jaw chuck. In a specific embodiment, the clamping mechanism 121 uses a three-jaw chuck; in a preferred embodiment, the clamping mechanism 121 uses a four-jaw chuck; in other embodiments, the clamping mechanism 121 uses a six-jaw chuck. All three methods can achieve the desired fixation of the camera lens, and the operator can choose which one to use based on the actual situation. By using a three-jaw chuck, a four-jaw chuck, or a six-jaw chuck to clamp and fix the camera lens, shaking of the camera lens during dispensing can be avoided.

[0043] Preferably, it also includes a slide rail 5 on the horizontally arranged workbench 1, a slider 6 slidably connected to the slide rail 5, and a fixed plate 7 connected to the slider 6. The fixed plate 7 can be driven to move above the camera lens by sliding the slider 6.

[0044] Furthermore, when clamping the camera lens, the bottom of the camera lens may be suspended in the air. When the vertical lifting mechanism 11 drives the dispensing needle 21 downward, the dispensing needle 21 is likely to touch the camera lens, thereby damaging the dispensing needle 21 or the camera lens. Therefore, after the clamping mechanism 121 fixes the camera lens, the worker can slide the slider 6 on the slide rail 5. When the fixing plate 7 can touch the camera lens, the worker will know that the bottom of the camera lens is suspended in the air and re-clamp the camera lens.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or modifications can be made without departing from the principles of the present invention. These improvements or modifications should also be regarded as the scope of protection of the present invention.
