Description

Technical Field

[0001] This utility model relates to the field of suction cups, and in particular to a suction cup device for a vacuum adsorption robot. Background Technology

[0002] Vacuum suction cups commonly used in industry often achieve adsorption by creating negative pressure by removing internal air; suction cups used in household or tool applications often generate suction by squeezing out air; in addition, there are magnetic suction cups that use magnetic force to attract metal parts. Their core function is to temporarily fix, move, or install objects without a complex fixing structure, and most of them can be flexibly disassembled and reused.

[0003] Before using the suction cup device of the vacuum adsorption robot, prepare the following: Inspect the appearance of the suction cup to ensure it is free of damage, deformation, or stains, and clean any debris from the adsorption surface. Confirm that the vacuum system is leak-free, the locking pin is securely connected to the suction cup, and the positioning components are functioning properly. Then, start the robot and the vacuum system. Adjust the vacuum level and control the suction force according to the weight, material, and surface flatness of the object to be adsorbed. Set the suction cup adsorption angle and movement path through the device control module. The robot then moves the suction cup above the target object, adjusts the suction cup to be perpendicular to the object surface, and starts the adsorption function. Once the vacuum system forms a stable negative pressure and the suction cup is tightly attached to the object, confirm that the adsorption is secure. Then, complete the object handling, assembly, and positioning operations according to the preset program. During the process, avoid violent vibration or external impact to prevent the suction cup from falling off. After the operation is completed, move the object to the target position, release the vacuum negative pressure through the device control, and after the suction cup naturally separates from the object surface, operate the robot to move the suction cup back to its original position. Regularly clean the suction cup adsorption surface and air pipe, and check the wear of the suction cup. If replacement is needed, follow the quick disassembly and assembly procedure.

[0004] Most suction cups on the market do not allow for individual adjustment of suction power, making it difficult to adapt to the adsorption needs of objects of different weights and materials. In actual operations, it is often necessary to simultaneously adsorb objects of different weights and materials. If the suction power is set according to the heavier objects, it is easy to damage light and fragile objects. If it is set according to the lighter objects, it will cause heavy objects to be not firmly adsorbed and easily fall off during transportation, affecting work efficiency and safety. When dealing with objects with different surface flatness, the uniform suction power cannot adapt to the degree of adhesion between each suction cup and the object surface. In areas of tight adhesion, excessive suction power may generate unnecessary stress, while in areas of slightly poor adhesion, insufficient suction power may cause the adsorption to loosen under slight external interference. Therefore, a suction cup device for a vacuum adsorption robot is proposed to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3The present invention provides an embodiment of a suction cup device for a vacuum adsorption robot, comprising a fixed outer shell 1. Inside the fixed outer shell 1 are a mechanism 2 for individually adjusting suction force and a disassembly mechanism 3. The mechanism 2 for individually adjusting suction force includes a rotating rod 214, which drives a helical gear 215 and a rotary gear 217 to rotate synchronously, providing a power transmission basis for suction force adjustment and angle adjustment. A helical gear 215 is fixedly connected to the outer wall of the rotating rod 214. The helical gear 215 meshes with a helical gear 216 or a helical gear 233 to achieve individual adjustment of the suction force of different suction cups 227. A helical gear 216 is meshed with the outer wall of the helical gear 215, transmitting power to a rotating rod 236, which drives a rotating baffle 232 to rotate. The rotating rod 236 is fixedly connected to the inner wall of the helical gear 216, causing the rotating baffle 232 to rotate within a fixed baffle 231, changing the overlap between the two. The rotating baffle 232 is fixedly connected to the end of the rotating rod 236 away from the helical gear 216. The rotating baffle 232 adjusts the airflow of the suction pipe 226 by changing the overlapping area with the fixed baffle 231, thereby changing the suction force of the corresponding suction cup 227. The inner wall of the fixed outer shell 1 is fixedly connected to the rotating plate 225 through the suction pipe 226. The rotating plate 225 carries the suction cup 227 and can rotate to adjust the angle so that the suction cup 227 can be adapted to different adsorption surfaces. At the same time, it provides an installation base for the disassembly mechanism 3. The inner wall of the suction pipe 226 is fixedly connected to the fixed baffle 231. The fixed baffle 231 and the rotating baffle 232 cooperate to form an airflow adjustment structure. The airflow is controlled by the relative rotation of the two. The inner wall of the fixed baffle 231 is rotatably connected to the outer wall of the rotating rod 236. The suction cup 227 is inserted into the inner wall of the rotating plate 225. The suction cup 227 adsorbs the target object by suction force. It can be quickly disassembled and replaced to adapt to different adsorption scenarios.

[0020] Reference Figures 3-5The suction force adjustment mechanism 2 also includes a sliding bracket 212, which carries the sliding shell 213 and the electric push rod 211. Driven by the electric push rod 228, it provides a basis for the positional adaptation of the angle adjustment components. The bottom end of the sliding bracket 212 is slidably connected to the inner wall of the fixed shell 1. The outer wall of the sliding bracket 212 is slidably connected to the sliding shell 213, which carries the motor 235 and the rotating rod 214. Driven by the electric push rod 211, it adjusts the position, realizing the meshing switching of the helical gear 215 and the power adaptation for angle adjustment. The inner wall of the sliding shell 213 is rotatably connected to the outer wall of the rotating rod 214. 14. A rotating gear 217 is fixedly connected to the end away from the helical gear 215. The rotating gear 217 meshes with the rotating gear 218, transmitting power to the worm 219. The outer wall of the rotating gear 217 is meshed with the rotating gear 218, which meshes with the rotating gear 217, driving the worm 219 to rotate synchronously, thus realizing the conversion of power direction. The inner wall of the rotating gear 218 is fixedly connected to the worm 219, which meshes with the worm wheel 220, transmitting power to the rotating rod 221. The outer wall of the worm 219 is meshed with the worm wheel 220, which meshes with the worm 219. The rotating rod 221 is driven to rotate, further changing the direction of power and ensuring stable power transmission for angle adjustment. The rotating rod 221 is fixedly connected to the inner wall of the worm gear 220. The rotating rod 221 is driven to rotate by the worm gear 220, which drives the helical gears 222 at both ends to rotate synchronously, providing power for the rotation of the connecting column 224. Helical gears 222 are fixedly connected to both ends of the rotating rod 221. The helical gears 222 mesh with the helical gears 223, transmitting power to the connecting column 224. The outer wall of the helical gears 222 meshes with the helical gears 223, which drive the connecting column 224 to rotate, thereby realizing the angle adjustment of the rotating plate 225. A connecting column 224 is fixedly connected to the inner wall of the helical gear 223. The connecting column 224 drives the rotating plate 225 to rotate synchronously, directly adjusting the adsorption angle of the suction cup 227. The outer wall of the connecting column 224 is fixedly connected to the inner wall of the rotating plate 225. The outer wall of the rotating rod 221 is rotatably connected to the inner wall of the fixed housing 1. The outer wall of the connecting column 224 is rotatably connected to the inner wall of the fixed housing 1. One end of the suction pipe 226 is fixedly connected to the inner wall of the fixed housing 1. The suction pipe 226 provides a channel for airflow delivery, supports the fixed wind baffle 231 and the support rod 230, and ensures stable suction adjustment. The other end of the suction pipe 226 is fixedly connected to the inner wall of the rotating plate 225.

[0021] Reference Figures 3-5The suction power adjustment mechanism 2 also includes a helical gear 5 233, which corresponds to the suction power adjustment of another set of suction cups 227. In conjunction with the engagement and switching of helical gear 1 215, it enables independent control of the suction power of the two different suction cups 227. Helical gear 5 233 is rotatably connected to the inner wall of the fixed housing 1, and its outer wall is engaged with the outer wall of helical gear 1 215. The suction power adjustment mechanism 2 also includes an electric actuator 228, which pushes the sliding bracket 212 to move. To provide a basis for adjusting the position of the sliding shell 213, the outer wall of the electric push rod 228 is fixedly connected to the inner wall of the fixed shell 1. The inner rod of the electric push rod 228 is fixedly connected to the side wall of the sliding bracket 212. The side wall of the sliding bracket 212 is fixedly connected to the electric push rod 211. The electric push rod 211 pushes the sliding shell 213 to slide. The inner rod of the electric push rod 211 is fixedly connected to the outer wall of the sliding shell 213. The suction force adjustment mechanism 2 also includes a motor 235, which provides the core power for the rotation of the rotating rod 214. The components for driving suction adjustment and angle adjustment are linked. The bottom end of the motor 235 is fixedly connected to the inner wall of the sliding shell 213. A support rod 230 is fixedly connected to the inner wall of the suction pipe 226. The support rod 230 supports the rotating rod 236 to rotate stably, preventing the rotating rod 236 from shaking and affecting the adjustment accuracy of the wind deflector. The inner wall of the support rod 230 is rotatably connected to the outer wall of the rotating rod 236. The outer wall of the rotating wind deflector 232 is rotatably connected to the inner wall of the fixed wind deflector 231. The disassembly mechanism 3 includes a locking pin 311. The locking pin 311 is spring-loaded. Spring 312's elastic force fixes the suction cup 227 in position; pressing it releases it from the suction cup 227, allowing for quick assembly and disassembly. The outer wall of locking pin 311 is elastically connected to the inner wall of rotating plate 225 via spring 312. Spring 312 provides elastic thrust, ensuring locking pin 311 remains tightly fixed to suction cup 227, guaranteeing stable installation. Locking pin 311's outer wall inserts into the inner wall of suction cup 227. A positioning hole 234 is provided at the top of the outer casing 1 for mounting the outer casing 1. One end of spring 312 is fixedly connected to the side wall of locking pin 311, and the other end is fixedly connected to the inner wall of rotating plate 225.

[0022] Working principle: The starting motor 235 drives the rotating rod 214 to rotate. When the rotating rod 214 rotates, it drives the helical gear 215 to rotate. The helical gear 215 meshes with and drives the helical gear 216, causing the rotating rod 236 to rotate. The rotating rod 236 drives the rotating baffle 232 to rotate within the fixed baffle 231. By changing the overlapping area of ​​the fixed baffle 231 and the rotating baffle 232, the airflow of the suction pipe 226 is adjusted. Activating the electric push rod 228 can switch the helical gear 215 to mesh with the helical gear 233, ultimately achieving individual adjustment of the suction force of the two different suction cups 227.

[0023] Electric actuator 228 is activated, pushing the sliding bracket 212 to move. Electric actuator 211 pushes the sliding shell 213 to adjust its position. Motor 235 on the inner wall of sliding shell 213 is activated, driving rotating rod 214 to rotate. Rotating rod 214 drives rotating gear 217 to mesh with rotating gear 218, causing worm gear 219 to rotate and mesh with worm wheel 220. Worm wheel 220 drives rotating rod 221 to rotate. Helical gear 3 222 at both ends of rotating rod 221 meshes with helical gear 4 223, thereby driving connecting column 224 and rotating plate 225 to rotate, adjusting the suction angle of suction cup 227 on rotating plate 225. When the suction cup 227 needs to be replaced, press the locking pin 311. The locking pin 311 compresses the spring 312 and disengages from the slot on the inner wall of the suction cup 227, so that the suction cup 227 can be removed from the rotating plate 225. When installing a new suction cup 227, release the locking pin 311. The spring 312 returns to its original position and pushes the locking pin 311 back into the inner wall of the suction cup 227. With the help of the positioning hole 234 on the top of the fixed housing 1, the suction cup 227 can be quickly disassembled and assembled.
