Description

Technical Field

[0001] The utility model relates to the technical field of camera module production, in particular to an adsorption device for a lens cover. Background Art

[0002] A camera module, also known as a camera module, is a modular product that integrates components such as a camera, lens, image sensor, digital signal processor, etc. It is widely used in cameras, mobile phones, computers, security monitoring, smart homes and other fields, bringing great convenience to our lives and work.

[0003] When a large-lens camera module is used, a lens cap is usually used to protect the mirror surface. Due to cost considerations, lens manufacturers often use thin materials with poor elasticity to make lens caps. Because the lens cap needs to be plugged in and out many times during the process of assembling the lens into a module, the lens cap may break due to uneven force during operation by the operator.

[0004] Therefore, in order to avoid damage to the lens cover due to plugging and unplugging during assembly of the camera module, we have designed a lens cover adsorption device. Utility Model Content

The adsorption holes 14 at the bottom of the lens cover adsorption cover 6 are all connected to the corresponding air collecting chamber 12, and the air pipe 13 is connected to the vacuum pump 17, so the vacuum pump 17 can be used to make the adsorption holes 14 generate adsorption force; an adjusting groove 501 is provided in the inner cavity of the support plate 5, and two adjusting sliders 10 driven by the adjusting screw 9 are slidably connected in the adjusting groove 501, and the bottom of the adjusting slider 10 is fixed to the top of the lens cover adsorption cover 6 by a movable shaft 11.

[0030] See also Figure 2 and Figure 7 In this embodiment, a vacuum pump 17 is also included. The air extraction end of the vacuum pump 17 is connected to the two air pipes 13 through two hoses respectively. The electric telescopic rod 3 and the vacuum pump 17 are connected to the mains through wires.

[0031] Specifically, when the vacuum pump 17 draws air, it can be done through the adsorption hole 14, thereby closing the lens cover 8 for adsorption, and the vacuum pump 17 is connected to the air pipe 13 through a hose, which facilitates the adjustment of the two lens cover adsorption covers 6 and avoids the problem of limitation and inability to move due to the hard pipe.

[0032] See also Figure 2 In this embodiment, the adjusting screw 9 passes through the inner cavity of the adjusting slot 501 from one side of the supporting plate 5, and two opposite threads are provided on the adjusting screw 9. The threads of the adjusting screw 9 pass through two adjusting sliders 10, and the two adjusting sliders 10 are respectively located on the two opposite threads of the adjusting screw 9.

[0033] Specifically, the adjusting screw 9 is designed with opposite threads at both ends, and each thread section is connected to an adjusting slider 10, so that when the adjusting screw 9 is turned, the two adjusting sliders 10 move closer to or away from each other, thereby achieving the purpose of adjusting the distance between the two lens cover adsorption covers 6.

[0034] See also Figure 2In this embodiment, one end of the adjusting screw 9 extending into the inner cavity of the adjusting slot 501 is rotatably connected to the inner wall of the adjusting slot 501, and one end of the adjusting screw 9 extending out of the adjusting slot 501 is rotatably connected to the side wall of the support plate 5.

[0035] Specifically, through the above design, the adjusting screw 9 can be rotated stably, and the smoothness of the adjusting screw 9 during rotation can be ensured.

[0036] See also Figure 2 and Figure 4 In this embodiment, a limiting groove 502 connected to the adjusting groove 501 is also provided at the bottom of the support plate 5, and the moving shaft rod 11 is slidably connected in the limiting groove 502, and the top of the moving shaft rod 11 is fixed to the bottom of the adjusting slider 10, and the bottom is fixed to the top of the lens cover adsorption cover 6.

[0038] See also Figure 2-6 In the present embodiment, telescopic cavities 15 are provided on both the front and rear sides of the inner top of the two lens cover adsorption covers 6, and a telescopic rod 16 is slidably connected between the two corresponding telescopic cavities 15 on the two lens cover adsorption covers 6; the lens cover adsorption covers 6 are made of elastic rubber, and each lens cover adsorption cover 6 has a semicircular structure design.

[0039] Specifically, through the designed telescopic rod 16, both ends of the telescopic rod 16 respectively extend into the telescopic cavities 15 opened on the two lens cover adsorption covers 6, so that the telescopic rod 16 can be used to connect the two lens cover adsorption covers 6, and can also play a supporting role for the connection between the lens cover adsorption covers 6 to ensure the stability of the two lens cover adsorption covers 6. The lens cover adsorption cover 6 is made of elastic rubber and has a semicircular structure because the soft rubber can avoid damage to the lens cover 8.

[0040] See also Figure 1 and Figure 8 In this embodiment, a lens body 7 is also included, and a lens cover 8 is buckled on the top of the lens body 7. A positioning groove 101 is opened at the top of the support base 1 and below the two lens cover adsorption covers 6, and the lens body 7 is placed in the positioning groove 101.

[0041] Specifically, the lens cover 8 designed on the lens body 7 plays a role in protecting the mirror surface of the lens body 7, and the positioning groove 101 designed on the supporting base 1 plays a role in facilitating the insertion of the lens body 7, and can ensure that the lens body 7 is located below the two lens cover adsorption covers 6, which plays a good positioning role and facilitates the adsorption of the two lens cover adsorption covers 6 on the lens cover 8 when they are lowered.

[0042] Working principle:

[0043] When it is necessary to remove the lens cover 8 from the lens body 7, the staff can start the electric telescopic rod 3 to lower the height of the support plate 5. After the height of the support plate 5 is lowered, the lens cover adsorption cover 6 can be driven to descend and gradually cover the top of the lens cover 8 (such as Figure 8 As shown), the vacuum pump 17 can be started. Since the vacuum pump 17 is connected to the air pipe 13 through a hose, and the air pipe 13 is connected to the air collecting chamber 12 and the adsorption hole 14, the adsorption hole 14 can adsorb the lens cover 8 through the suction effect of the vacuum pump 17. The electric telescopic rod 3 is started again, and the power output shaft of the electric telescopic rod 3 pushes the support plate 5 to rise, thereby driving the lens cover adsorption cover 6 and the lens cover 8 adsorbed thereto to rise, so that the lens cover 8 is away from the lens body 7;

[0044] When it is necessary to adjust the distance between the two lens cover adsorption covers 6 to adjust the covering area of ​​the lens cover adsorption covers 6, the staff only needs to twist the adjusting screw 9, thereby using the rotation of the adjusting screw 9 to drive the two adjusting sliders 10 to move closer to or away from each other, thereby using the movable shaft 11 to drive the two lens cover adsorption covers 6 to move closer to or away from each other. When the two lens cover adsorption covers 6 are moving, due to the support and connection of the telescopic rod 16, the connection stability of the lens cover adsorption covers 6 can be improved, and the telescopic rod 16 can be convenient for the telescopic action in the telescopic cavity 15. When the distance of the lens cover adsorption covers 6 is adjusted, the rotation of the adjusting screw 9 can be stopped.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
