Description

Technical Field

[0001] This utility model belongs to the field of lenses, specifically relating to a pickup and fixing component, a moving mechanism and a coupling device. Background Technology

[0002] Lenses are optical components widely used in optical devices, and they are usually fixed to PCB boards by adhesive bonding. When mounting a lens on a PCB board, in order to ensure precise coupling of the lens, a lens moving mechanism is usually required to move the lens precisely to ensure that the lens mounting position does not shift.

[0003] Lens moving mechanisms typically include a pick-and-hold assembly for securing the lens to prevent it from falling during movement. Existing pick-and-hold assemblies are typically nozzles that create negative pressure at their openings to adhere and hold the lens (see application number 202211053358.1, entitled "Prior Art of a Coupling System and Lens Assembly Method").

[0004] However, in practice, it has been found that when using only the suction nozzle to fix the lens, the lens is prone to falling off during movement. Once the lens falls off, it is easily lost. Utility Model Content

[0005] This invention provides a pickup and fixing component, the purpose of which is to solve the problem of lenses falling off during movement.

[0006] To achieve the above objectives, this utility model provides a pickup and fixing component, including...

[0007] Adsorption structure, said adsorption structure including a nozzle; and

[0008] The clamping structure includes a first clamping component, a second clamping component, and a clamping device. The first clamping component and the second clamping component are disposed opposite to each other, and the suction nozzle is disposed between the first clamping component and the second clamping component. The first clamping component and the second clamping component are connected to the clamping device, and the clamping device is used to drive the first clamping component and the second clamping component to move closer together to achieve clamping and fixing of the lens.

[0009] This solution uses a suction nozzle to adsorb the lens through negative pressure. The nozzle can pick up the lens from the lens container and also fix the lens in place during movement to prevent it from falling. Simultaneously, when the nozzle adsorbs the lens, the first and second clamping components further clamp and secure the lens. The lens is constrained by both negative pressure and clamping force, resulting in more stable lens fixation and preventing it from falling during movement, thus overcoming the shortcomings of existing technologies.

[0010] Preferably, in order to fit snugly against the lens surface, the first clamping component in this design includes a first clamping surface, which is a plane. This design, by having the first clamping surface fit snugly against the lens surface, results in more stable lens fixation.

[0011] To ensure proper contact with the lens surface, the second clamping component in this design includes a second clamping surface, which is planar. This design, by ensuring the second clamping surface is in contact with the lens surface, results in more stable lens fixation.

[0012] Preferably, to solve the problem of interference between the first and second clamping components and the suction nozzle, this solution includes a clamping portion in both the first and second clamping components, and the clamping portion is L-shaped. In this solution, the first and second clamping components have L-shaped clamping portions that contact the lens, and the suction nozzle is located between the two L-shaped clamping portions. The L-shaped clamping portions provide space for the suction nozzle, thus avoiding interference between the clamping portions and the suction nozzle.

[0013] Preferably, since multiple devices are often installed in the overhead space, interference should be minimized. The first and second clamping components include a connecting portion, which is connected to the clamp. The clamping portion and the connecting portion are arranged in a V-shape. In this design, the clamping portion contacts the lens, while the connecting portion is used for connection and fixation. Therefore, when the clamping portion and the connecting portion are arranged in a V-shape, the space above the clamping portion is left open, thus avoiding interference between the clamping components and other devices.

[0014] Preferably, for the installation of the suction nozzle, the adsorption structure of this solution further includes a connecting component. The suction nozzle is installed on the connecting component, and the connecting component has an internal airflow channel that communicates with the suction nozzle. This solution uses the connecting component as the mounting base for the suction nozzle, ensuring stable installation. Simultaneously, a negative pressure source is connected to the connecting component, providing adsorption force to ensure the suction nozzle can adsorb and fix the lens.

[0015] Preferably, since multiple devices are often installed in the overhead space, the connecting component described in this solution is U-shaped, V-shaped, or arc-shaped to minimize interference.

[0016] Preferably, to secure the suction unit and the clamping unit, this solution further includes a mounting frame, on which the suction structure and the clamping structure are mounted. This solution mounts both the suction unit and the clamping unit onto the mounting frame, which serves as the mounting base for both. Furthermore, once the suction unit and the clamping unit are mounted onto the mounting frame, their positions are fixed, preventing interference between them.

[0017] In order to achieve the movement of the lens, the second aspect of this utility model discloses a moving mechanism, including the above-mentioned pickup and fixing component and moving component, wherein the pickup and fixing component is connected to the moving component, and the moving component can drive the pickup and fixing component to move.

[0018] In this solution, the picking and fixing component picks up the lens from the lens container, and then the moving component drives the picking and fixing component to move, thereby moving the lens.

[0019] Preferably, the moving component of this solution includes a coupling platform, which is used to drive the picking and fixing component to move.

[0020] The moving component in this solution includes a tilt displacement stage, which is used to adjust the angle of the picking and fixing component.

[0021] The third aspect of this utility model discloses a coupling device, characterized in that it includes the aforementioned moving mechanism. By incorporating this moving mechanism into the coupling device, the lens becomes more stable during movement, preventing it from falling off.

[0022] The beneficial effects of this invention are as follows: This design uses a suction nozzle to adsorb the lens via negative pressure. The nozzle can pick up the lens from the lens container and also fix the lens during movement, preventing it from falling. Simultaneously, when the nozzle adsorbs the lens, the first and second clamping components further clamp and fix the lens. The lens is simultaneously constrained by negative pressure and clamping force, resulting in more stable lens fixation and preventing the lens from falling during movement, thus overcoming the shortcomings of existing technologies.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0030] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.

[0031] Example 1

[0032] The basics are as follows: Figure 1 As shown, a pickup and fixing assembly includes an adsorption structure 1, a clamping structure 2, and a mounting frame 3, wherein the adsorption structure 1 and the clamping structure 2 are mounted on the mounting frame 3. In practice, the adsorption structure 1 and the clamping structure 2 can be connected to the mounting frame 3 by welding or by using fasteners.

[0033] like Figure 2 As shown, the adsorption structure 1 in this embodiment includes a suction nozzle 11, a connecting component 12, and a negative pressure source. The connecting component 12 is made of metal and has an internal airflow channel. The connecting component 12 can be U-shaped, V-shaped, or arc-shaped. The suction nozzle 11 and the negative pressure source are respectively installed at both ends of the connecting component 12, and the suction nozzle 11 is connected to the airflow channel inside the connecting component 12. The negative pressure source can be a vacuum pump, and the negative pressure source is connected to the airflow channel.

[0034] Taking one application scenario as an example: When a lens needs to be picked up, the suction nozzle 11 contacts the lens surface. Then, the negative pressure source works, creating a negative pressure at the opening of the suction nozzle 11. The suction nozzle 11 uses the negative pressure to attract and fix the lens, thus picking up the lens.

[0035] like Figure 3As shown, the clamping structure 2 of this embodiment includes a first clamping component 21, a second clamping component 22, and a clamping device 23. The first clamping component 21 and the second clamping component 22 are respectively disposed on both sides of the suction nozzle 11, and the suction nozzle 11 is accommodated between the first clamping component 21 and the second clamping component 22. The first clamping component 21 and the second clamping component 22 are connected to the clamping device 23. When the clamping device 23 is working, it drives the first clamping component 21 and the second clamping component 22 to move closer to each other and further away from each other. When the first clamping component 21 and the second clamping component 22 move closer to each other, they clamp and fix the lens; when they move further away from each other, they release the lens. In this embodiment, the clamping device 23 preferably uses a clamping motor, but in some other embodiments, the clamping device 23 can also be a clamping cylinder.

[0036] like Figure 4 and Figure 5 As shown, the first clamping component 21 and the second clamping component 22 in this embodiment have the same structure. Both the first clamping component 21 and the second clamping component 22 include a clamping portion 211 and a connecting portion 212, which are arranged in a V-shape. The clamping portion 211 of the first clamping component 21 is provided with a first clamping surface 213, and the clamping portion 211 of the second clamping component 22 is provided with a second clamping surface 221. The first clamping surface 213 and the second clamping surface 221 are parallel to each other, and both the first clamping surface 213 and the second clamping surface 221 are parallel to the suction nozzle 11, which is located between the first clamping surface 213 and the second clamping surface 221. The first clamping surface 213 and the second clamping surface 221 extend to the bottom of the suction nozzle 11.

[0037] Taking one application scenario as an example: After the suction nozzle 11 adsorbs the lens, the clamp 23 operates, causing the first clamping component 21 and the second clamping component 22 to move closer together. The first clamping component 21 and the second clamping component 22 cooperate to clamp and fix the lens. The suction nozzle 11 fixes the lens through negative pressure adsorption, and the first clamping component 21 and the second clamping component 22 cooperate to clamp and fix the lens. The lens is simultaneously subjected to negative pressure adsorption force and clamping fixing force, making the lens more stable.

[0038] Example 2

[0039] This embodiment provides a moving mechanism, including the pickup and fixing component and the moving component of Embodiment 1. The moving component drives the pickup and fixing component to move precisely, thereby achieving lens coupling.

[0040] The moving component in this embodiment includes a tilt displacement stage and a coupling platform. The tilt displacement stage is fixedly connected to the mounting bracket 3, and then mounted on the coupling platform. When the tilt displacement stage and the coupling platform are working, they drive the pickup and fixing component to move, ensuring that the lens can be moved to the position where coupling is required.

[0041] Example 3

[0042] This embodiment provides a coupling device, including the moving mechanism, PCB board fixing mechanism, glue application mechanism and fixing mechanism of Embodiment 2.

[0043] In this embodiment, the PCB board fixing mechanism is used to fix the PCB board in a horizontal position. The moving mechanism moves the lens from the lens container to the coupling position on the PCB board. The adhesive dispensing mechanism is used to release adhesive onto the coupling position on the PCB board.
