Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a lens holder for gripping a robotic arm. Background Technology

[0002] In fields such as industrial automation, logistics sorting, and precision assembly, gripping robotic arms often require cameras to identify, locate, and monitor target objects, thereby improving operational accuracy and intelligence. However, existing lens mounts for gripping robotic arms are mostly fixed or only allow for angle adjustment in a single direction, making it difficult to meet the observation needs in complex scenarios. For example, when the robotic arm grips objects of different sizes and shapes, or when there are obstacles obstructing the working environment, fixed lenses often cannot flexibly adjust the shooting angle, resulting in incomplete image acquisition, increased target recognition errors, and consequently affecting the robotic arm's operational efficiency and reliability. Furthermore, some adjustable lens mounts have complex structures, cumbersome adjustment processes, and limited adjustment ranges, making it difficult to achieve multi-dimensional, wide-range angle changes and adapt to diverse working scenarios, thus limiting the application flexibility of gripping robotic arms. Therefore, this paper proposes a lens mount for gripping robotic arms to address the aforementioned problems. Utility Model Content

[0003] This invention addresses the problem that existing lens holders for gripping robotic arms are mostly fixed or can only achieve angle adjustment in one direction. It provides a lens holder for gripping robotic arms that can be adjusted in real time with multiple degrees of freedom, thereby adapting to different working scenarios and effectively solving the problems mentioned in the background.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A lens holder for gripping a robotic arm includes a robotic arm with a fixed base at its front end. The fixed base has two grippers that can move inward at its front end. The inner wall of the fixed base has a rotatable support platform. A camera is mounted on the upper end of the support platform. A rotatable worm gear is also mounted on the upper end of the support platform. When the worm gear rotates, it can cause the camera to flip and swing up and down. When the support platform rotates and moves, it can cause the camera to tilt and swing left and right.

[0006] The inner wall of the front end of the fixed base is provided with two clamps that can move left and right, and the claws are fixedly connected to the corresponding clamps.

[0007] The inner wall of the front end of the fixed base is also provided with a double-headed telescopic rod, and the clamp is fixedly connected to both sides of the double-headed telescopic rod.

[0008] Anti-slip pads are provided on the inner end faces of the two grippers.

[0009] The support platform is rotatably connected to the inner wall of the fixed base. A gear ring is fixedly connected to the outer surface of the support platform. The inner wall of the fixed base is also provided with a first motor. A small gear that meshes with the gear ring is fixedly connected to the output end of the first motor.

[0010] A second motor is fixedly connected to the upper surface of the support platform, and a worm gear is fixedly connected to the output end of the second motor. The worm gear is also rotatably connected to the upper surface of the support platform.

[0011] A worm wheel is engaged at the upper end of the outer surface of the worm, and the worm wheel is rotatably connected to the upper end of the support platform. The camera is mounted on the worm wheel.

[0012] Both sides of the worm gear are coaxially fixed with connecting plates, and the camera is fixed to the upper surface of the two connecting plates.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] During use, the rotating support platform drives the camera to tilt and swing left and right, while the rotating worm gear drives the camera to tilt and swing up and down, thus allowing for angle adjustment to adapt to different scenarios. The camera itself is existing technology and will not be described in detail. The camera features multi-degree-of-freedom adjustment, enabling flexible angle adjustment in multiple directions. This characteristic allows for quick adjustment of the camera's shooting position and angle according to different operational needs. For example, when gripping small precision parts, the lens can be fine-tuned to obtain clear, detailed images. When handling large objects or complex stacking scenarios, a wide range of angle adjustments can be used to avoid obstacles and ensure complete capture of the target area. Furthermore, the multi-angle adjustment structure of the mounting frame is simple in design and easy to operate, achieving precise adjustment without complex manual intervention or additional drive devices. This effectively improves the adaptability and operational efficiency of the gripping robotic arm in diverse scenarios, reduces operational errors caused by mismatched lens angles, and broadens the application scope of the robotic arm in industrial inspection, logistics sorting, and other fields.

Detailed Implementation

[0021] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1-5 As shown, this utility model provides a lens holder for gripping a robotic arm, including a robotic arm 1. The front end of the robotic arm 1 is provided with a fixed seat 2, and the front end of the fixed seat 2 is provided with two grippers 4 that can move inward. The inner wall of the fixed seat 2 is provided with a rotatable support platform 11, and a camera 16 is provided on the upper end of the support platform 11. The upper end of the support platform 11 is also provided with a rotatable worm gear 13. When the worm gear 13 rotates, it can make the camera 16 flip and swing up and down. When the support platform 11 rotates and moves, it can make the camera 16 deflect and swing left and right.

[0023] like Figures 1-4 As shown, robotic arm 1 is existing technology and will not be described in detail. The fixed base 2 is fixed to the front end of robotic arm 1. Through the provided grippers 4, when the two grippers 4 move inward, they can clamp and fix the target object. Through the provided rotatable support platform 11, when the support platform 11 rotates, it can drive the camera 16 to tilt left and right. Through the provided worm gear 13, when the worm gear 13 rotates, it can drive the camera 16 to tilt up and down, thus allowing for angle adjustment of the camera 16 to adapt to different scenarios. The camera 16 is existing technology and will not be described in detail. The camera 16 has a multi-degree-of-freedom adjustment function, enabling flexible angle adjustment of the camera 16 in multiple directions. This feature... This allows the camera 16 to quickly adjust its shooting position and angle according to different work scenarios. For example, when gripping small precision parts, the lens can be finely adjusted to obtain clear and detailed images. When handling large objects or complex stacking scenarios, it can avoid obstacles through a wide range of angle adjustments to ensure complete capture of the target area. At the same time, the multi-angle adjustment structure of the mounting frame is simple in design and easy to operate. It can achieve precise adjustment without complicated manual intervention or additional drive devices, effectively improving the adaptability and work efficiency of the gripping robotic arm 1 in diverse scenarios, reducing operational errors caused by lens angle mismatch, and broadening the application scope of the robotic arm 1 in industrial inspection, logistics sorting and other fields.

[0024] The inner wall of the front end of the fixed base 2 is provided with two clamps 3 that can move left and right, and the claws 4 are fixedly connected to the corresponding clamps 3.

[0025] like Figure 2 and Figure 3 As shown, the clamp 3 can slide left and right on the inner wall of the fixed seat 2. The gripper 4 is fixed to the clamp 3 by bolts. When the clamp 3 moves inward or outward, it can drive the gripper 4 to move inward or outward.

[0026] The inner wall of the front end of the fixed base 2 is also provided with a double-headed telescopic rod 6, and the clamp 3 is fixedly connected to both sides of the double-headed telescopic rod 6.

[0027] like Figure 3 As shown, a connecting seat 7 is also fixedly connected to the inner wall of the front end of the fixed seat 2. The double-headed telescopic rod 6 is fixedly connected to the inner wall of the connecting seat 7, which is equivalent to the double-headed telescopic rod 6 being fixedly connected to the inner wall of the fixed seat 2. When working, the double-headed telescopic rod 6 can drive the two clamps 3 to move inward or outward. The double-headed telescopic rod 6 is existing technology and will not be described in detail.

[0028] Anti-slip pads 5 are provided on the inner end faces of the two grippers 4.

[0029] like Figure 2 As shown, the anti-slip pad 5 is attached to the inner wall of the gripper 4. When the gripper 4 grips an item, the anti-slip pad 5 can increase the friction to prevent the item from slipping.

[0030] The support platform 11 is rotatably connected to the inner wall of the fixed base 2. A gear ring 10 is fixedly connected to the outer surface of the support platform 11. The inner wall of the fixed base 2 is also provided with a first motor 8. A small gear that meshes with the gear ring 10 is fixedly connected to the output end of the first motor 8.

[0031] like Figure 2 As shown, the first motor 8 is fixed to the inner wall of the fixed base 2. The function of the first motor 8 is to provide rotational power for the support platform 11. The motor is existing technology and will not be described in detail. When the first motor 8 is started, it can drive the small spur gear 9 to rotate. When the small spur gear 9 rotates, it can drive the gear ring 10 and the support platform 11 to rotate through meshing with the gear ring 10, thereby driving the camera 16 to move in a circle, that is, to sway left and right.

[0032] The second motor 12 is fixedly connected to the upper surface of the support platform 11, and the worm gear 13 is fixedly connected to the output end of the second motor 12. The worm gear 13 is also rotatably connected to the upper end of the support platform 11.

[0033] like Figure 5 As shown, the function of the second motor 12 is to provide rotational power for the worm gear 13. A bearing seat is rotatably connected to one side of the outer surface of the worm gear 13. The bottom end of the bearing seat is fixed to the upper surface of the support platform 11, limiting the worm gear 13 to rotate only on the upper end of the support platform 11.

[0034] The upper end of the outer surface of the worm gear 13 is engaged with a worm wheel 14, which is rotatably connected to the upper end of the support platform 11. The camera 16 is mounted on the worm wheel 14.

[0035] like Figure 5 As shown, a rotating shaft is fixed to the inner wall of the worm gear 14 at its center. Support seats 17 are rotatably connected to the left and right ends of the outer surface of the rotating shaft. The bottom end of the support seat 17 is fixed to the upper surface of the support platform 11, which is equivalent to the worm gear 14 being rotatably connected to the upper end of the support platform 11. When the worm 13 rotates, it can drive the worm gear 14 to rotate through meshing with the worm gear 14, which in turn drives the camera 16 to flip and swing up and down. Furthermore, the worm gear 14 and worm 13 have high precision and can be finely adjusted.

[0036] Both sides of the worm gear 14 are coaxially fixed with connecting plates 15, and the camera 16 is fixed to the upper surface of the two connecting plates 15.

[0037] like Figure 5 As shown, with the connection between the connecting plate 15 and the worm gear 14, the camera 16 is essentially fixed to the upper end of the worm gear 14, meaning that when the worm gear 14 rotates, it can drive the camera 16 to flip up and down.

[0038] In use, when the support platform 11 rotates, it can drive the camera 16 to tilt and swing left and right. When the worm gear 13 rotates, it can drive the camera 16 to flip and swing up and down, thereby adjusting the angle of the camera 16 to adapt to different scenarios. The camera 16 is existing technology and will not be described in detail. The camera 16 has a multi-degree-of-freedom adjustment function, which can realize flexible angle adjustment of the camera 16 in multiple directions. This feature allows it to quickly adjust the shooting position and angle of the camera 16 according to the needs of different work scenarios. For example, when gripping small precision parts, the lens can be finely adjusted to obtain clear detail images. When dealing with large objects or complex stacking scenarios, it can avoid obstacles through a wide range of angle adjustments to ensure complete capture of the target area. At the same time, the multi-angle adjustment structure of the fixed frame is simple in design and easy to operate. It can achieve precise adjustment without complicated manual intervention or additional drive devices, effectively improving the adaptability and work efficiency of the gripping robot arm 1 in diverse scenarios, reducing the operation error caused by lens angle mismatch, and broadening the application range of the robot arm 1 in industrial inspection, logistics sorting and other fields.
