Description

Technical Field

[0001] This utility model relates to a lens assembly robot, belonging to the field of lens assembly production technology. Background Technology

[0002] In automated lens assembly lines, to connect the lens and its corresponding motherboard, both the motherboard and lens need to be picked up simultaneously at the material preparation end and automatically assembled using appropriate installation methods. When the robotic arm in the material preparation area picks up items, it can typically only pick up single items corresponding to the product type. However, for automated lens production and assembly lines, if items need to be picked up twice, either two robotic arms must be set up to ensure production efficiency, or the picking head must be changed during production to adapt to the corresponding items. Neither of these methods can simultaneously achieve optimal space utilization, production efficiency, and application cost. Therefore, a special robotic arm is needed that can simultaneously pick up two items to be connected, thus balancing production efficiency and application cost. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a lens assembly robot that can simultaneously handle the motherboard and lens in automatic lens assembly operations. This can ensure production efficiency and good application cost while taking into account space utilization.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides a lens assembly robot, including a robotic arm and a mounting frame installed at the end of the robotic arm. The robotic arm can at least drive the mounting frame to rotate. A motherboard gripping module and a lens picking and placing module are respectively installed on both sides of the mounting frame. The bottom of the motherboard gripping module is provided with a suction cup for adsorbing the motherboard. The lens picking and placing module includes a first drive module, a second drive module, and a gripper. The first drive module is used to drive the second drive module to rise and fall, and the second drive module is used to drive the gripper to close.

[0006] Specifically, the first drive module is a slide cylinder. A guide mechanism is installed vertically on the sliding surface of the slide cylinder. A guide block is slidably disposed on the guide mechanism. A positioning block and a limiting block for abutting the guide block are also installed on the sliding surface of the slide cylinder. A first elastic element is disposed between the positioning block and the guide block. The first elastic element is used to abut the guide block against the limiting block. The second drive module is fixedly disposed at the bottom of the guide block.

[0007] Specifically, the guide block is also provided with a third drive module, which is used to drive the connector connected to its output end to rotate. An air blowing pipe is installed on the connector, and the air blowing end of the air blowing pipe is not on the same straight line as the rotation axis of the connector.

[0008] Specifically, the motherboard gripping module includes a fourth drive module, which is a slide cylinder. A mounting plate is slidably disposed on the sliding surface of the fourth drive module in the vertical direction. A suction head is installed at the bottom of the mounting plate. A limiting member for restricting the mounting plate is also provided on the sliding surface of the slide cylinder. A second elastic member is also provided on the sliding surface of the slide cylinder. The second elastic member is used to press the mounting plate against the limiting member.

[0009] Specifically, the mounting bracket includes no less than three mounting surfaces. The motherboard gripping module and the lens picking and placing module are respectively mounted on two corresponding mounting surfaces. A camera assembly is mounted on the other mounting surface. The camera assembly includes a camera and a ring-shaped light strip mounted below the camera.

[0010] Specifically, the mounting bracket includes no less than three mounting surfaces. The motherboard gripping module and the lens picking and placing module are respectively mounted on two corresponding mounting surfaces, and a dust removal pipe is mounted on the other mounting surface.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

By rotating the mounting frame, the motherboard gripping module and the lens picking and placing module can perform gripping actions at the corresponding material preparation station. The picking of two different objects can be completed simultaneously without changing the picking head or a second robotic arm, thereby quickly meeting the subsequent assembly requirements, simplifying application costs, and effectively improving the space utilization of the equipment.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0024] This utility model provides a lens assembly robot that can simultaneously handle motherboards and lenses during automated lens assembly operations. It balances space utilization with production efficiency and cost-effectiveness. To achieve the robot's structural functions, the structure includes a robotic arm 1 and a mounting frame 2 installed at the end of the robotic arm 1. The robotic arm 1 is designed to drive the mounting frame 2 to rotate. A motherboard gripping module 3 and a lens picking and placing module 4 are respectively mounted on both sides of the mounting frame 2. A suction cup is provided at the bottom of the motherboard gripping module 3 to adhere to the motherboard, utilizing negative pressure to achieve the gripping action. The suction cup's position should match the motherboard's position. Since lenses often have a columnar structure, the lens picking and placing module 4 includes a first drive module 401, a second drive module 406, and a gripper 407 to achieve lens gripping and placement. Specifically, the first drive module 401 drives the second drive module 406 to rise and fall, while the second drive module 406 drives the gripper 407 to close and retract. (See reference...) Figures 2-5 As shown, the first drive module 401 can be driven by a cylinder, and the second drive module 406, to simplify the structural design, can be directly set as a gripper cylinder. The gripper cylinder directly drives the gripper 407 to close, thereby directly realizing the gripping action of the lens. When the equipment is in operation, neither of the two gripping parts is located on the rotation axis of the output end of the robotic arm 1. Therefore, when the robotic arm 1 rotates the mounting bracket 2, it can make the motherboard gripping module 3 and the lens picking and placing module 4 rotate to the picking station and the placing station respectively. The action only requires rotation to pick up. The structure and action method are simple, and the picking and placing of the motherboard and the lens can be completed simultaneously without the participation of an additional robotic arm.

[0025] This utility model provides a lens assembly robot. Since lenses are mainly placed by lifting, to prevent inaccurate vertical movement of the lens and subsequent compression of the placement surface, thus avoiding damage to the lens, the first drive module 401 is configured as a slide cylinder, and a guide mechanism 402 is installed vertically on the sliding surface of the slide cylinder. Figure 3As shown, a guide block 403 is slidably disposed on the guide mechanism 402. A positioning block 404 and a limiting block for abutting the guide block 403 are also installed on the sliding surface of the slide cylinder. A first elastic element 405 is disposed between the positioning block 404 and the guide block 403. If a spring or other mechanism is used, the first elastic element 405 is used to abut the guide block 403 against the limiting block. With the above arrangement, in the natural state, the first elastic element 405 abuts and positions the guide block 403 downward. At this time, the second drive module 406 is fixedly disposed at the bottom of the guide block 403. When the robotic arm 1 is moving the lens and the lens is subjected to a certain amount of pressure, the reverse force of the lens can make the guide block 403 overcome the elastic force of the first elastic element 405 and float upward, thereby avoiding hard pressure damage to the lens caused by deviations in position accuracy, which helps to ensure the quality of lens handling.

[0026] This utility model provides a lens assembly robot. Before installing the lens after it has been picked up, it is necessary to ensure that the mounting surface of the lens and the motherboard is clean and free of foreign objects. To ensure the cleanliness of the lens end face, a third drive module 408 is also provided on the guide block 403, which can be referred to as... Figure 4 As shown, a third drive module 408 is provided to drive the connector 409 connected to its output end to rotate. The third drive module 408 can be a rotary cylinder or the like. An air blowing pipe 410 is installed on the connector 409. The end of the air blowing pipe 410 is driven to rotate by the third drive module 408, thereby performing a dust cleaning operation at the lens connection position. For this purpose, it is necessary to ensure that the air blowing end of the air blowing pipe 410 is not on the same straight line as the rotation axis of the connector 409. As another preferred embodiment, the end of the air blowing pipe 410 can also be sealed, and multiple air blowing holes can be opened along the axial direction of the pipe section, so that the lens mounting surface can be blown clean from multiple directions and over a large area during rotation, thereby ensuring the cleanliness of the connection position.

[0027] This utility model provides a lens assembly robot. To prevent damage to the motherboard caused by inaccurate vertical positioning of the motherboard gripping module 3 during motherboard handling, the motherboard gripping module 3 can be configured to include a fourth drive module 301, such as... Figure 5As shown, the fourth drive module 301 can be configured as a sliding cylinder. A mounting plate 302 is vertically slidably mounted on the sliding surface of the fourth drive module 301, and a suction head 303 is mounted at the bottom of the mounting plate 302 for adsorbing the motherboard. To prevent the mounting plate 302 from slipping, a limiting member is provided on the sliding surface of the sliding cylinder to restrict the mounting plate 302. A second elastic member 304 is also provided on the sliding surface of the sliding cylinder. The second elastic member 304 is used to press the mounting plate 302 against the limiting member. Therefore, when the suction head 303 adsorbs or places the motherboard, if significant pressure is applied to the motherboard, the mounting plate 302 can automatically rise to balance the pressure, thus preventing damage to the motherboard to some extent. The structure of the suction head 303 can be referred to... Figure 5 As shown, the suction cup is partially hidden in a blind hole, which ensures good contact and adsorption effect.

[0028] This utility model provides a lens assembly robot. To facilitate the inspection of the appearance of components before installation and avoid the installation of defective products, the mounting frame 2 can be configured with at least three mounting surfaces. The motherboard gripping module 3 and the lens picking and placing module 4 are respectively mounted on two corresponding mounting surfaces, and a camera assembly 5 is mounted on the other mounting surface. The camera assembly 5 includes a camera 501 and a ring-shaped light strip 502 installed below the camera 501. The ring-shaped light strip 502 is used to provide illumination to ensure that the camera 501 can capture images effectively. As another embodiment, to facilitate the absorption of industrial dust, a dust removal pipe 6 can be installed on another mounting surface or an additional mounting surface. The dust removal pipe 6 is a telescopic flexible hose connected to a vacuum generator 8 and a filter assembly (not shown in the figure). The vacuum generator 8 can be mounted on the robotic arm 1 and move with the robotic arm 1.

[0029] The lens assembly robot provided in this embodiment of the utility model can also have an integrated terminal block 7 installed on the mounting frame 2 to facilitate the electrical connection between the various components and the control unit. The terminal block is used to connect the corresponding circuit elements.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
