Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a multi-station gripping and flipping robotic arm robot. Background Technology

[0002] In the context of the rapid development of industrial automation, robotic arms, as one of the core equipment of intelligent manufacturing, are profoundly changing the production mode of traditional manufacturing industries. From automobile manufacturing to electronic assembly, from logistics warehousing to aerospace, robotic arms, with their advantages of high precision, high efficiency, and strong repeatability, have become an indispensable tool for realizing production automation and intelligence.

[0003] However, as industrial production demands increasing flexibility and versatility from equipment, traditional robotic arms have revealed significant limitations in certain specific application scenarios, especially in situations where material clamping and flipping operations need to be performed simultaneously, such as workpiece positioning before welding, surface treatment before painting, and component adjustment during assembly. Existing robotic arms often struggle to meet the complex and ever-changing process requirements.

[0004] Therefore, in order to address the above problems, the applicant needs to design a multi-station gripping and flipping robotic arm to solve the problem. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station gripping and flipping robotic arm to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station gripping and flipping robotic arm, including a base,

[0007] It also includes: a robotic arm mechanism disposed above the base, the robotic arm mechanism comprising a support base, and a clamping component for gripping and flipping materials disposed inside the support base, the clamping component comprising a hollow sleeve fixedly connected to the support base, and a rotating sleeve rotatably disposed inside the hollow sleeve, a support shell fixedly disposed on the rotating sleeve, and a movable plate rotatably disposed inside the support shell, a gripping hand rotatably disposed inside the movable plate, the gripping hand being used to grip materials, a servo motor located inside the rotating sleeve fixedly disposed inside the hollow sleeve, and a threaded post disposed at the output end of the servo motor, a gear disk meshing on the threaded post, and the gear disk rotatably disposed inside the support shell and fixedly connected to the movable plate.

[0008] Furthermore, a fixing block is fixedly installed on the threaded column, and an extension plate is fixedly installed on the fixing block. A fixing plate is fixedly installed on the support shell, and the fixing plate and the extension plate cooperate to drive the support shell to rotate through the rotating sleeve.

[0009] Through the above structural design, the linkage design of the fixed block, extension plate, and fixed plate realizes the efficient transmission of servo motor power to the support shell. This structure, through rigid connection and meshing transmission, can precisely control the rotation angle of the rotating sleeve.

[0010] Furthermore, a base is fixedly connected to the base, and a stabilizing seat is fixedly provided on the base. A connecting arm is rotatably provided above the stabilizing seat, and a connecting member is rotatably provided at the end of the connecting arm away from the stabilizing seat and fixedly connected to the support base.

[0011] Through the above structural design, the composite support structure consisting of the base, the stabilizing seat, and the connecting arm significantly improves the vibration resistance and load-bearing capacity of the robotic arm through multi-point distributed load design, resulting in high stability.

[0012] Furthermore, a connecting block is fixedly provided on the connector, and a telescopic rod is rotatably provided on the connecting block, with the end of the telescopic rod away from the connecting block being rotatably connected to the base.

[0013] Through the above structural design, the hinged design of the telescopic rod and the connecting block gives the robotic arm mechanism multi-degree-of-freedom motion characteristics. By dynamically adjusting the length of the telescopic rod, the path deviation caused by the swing of the connecting arm can be compensated in real time, which expands the operating range of the robotic arm in narrow spaces or environments with many obstacles. It is particularly suitable for grasping and adjusting the posture of complex stacked materials in warehousing and logistics.

[0014] Furthermore, a fixing rod is provided inside the support shell, and a limiting plate is rotatably mounted on the fixing rod, and the limiting plate is rotatably connected to the clamping hand.

[0015] Through the above structural design, the secondary constraint mechanism formed by the fixed rod and the limiting plate realizes dynamic self-correction of the clamping state of irregular materials by synchronously following the rotation trajectory of the clamping hand.

[0016] Furthermore, the base is provided with a multi-station operating platform adapted to the robotic arm mechanism, and the inner side of the multi-station operating platform is provided with an operating area.

[0017] With the above structural design, operators can easily work on the multi-station operating platform using the robotic arm mechanism within the operating area.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the multi-station clamping and flipping robotic arm is convenient to clamp and flip materials, and is easy to use. The specific details are as follows:

[0019] When this multi-station clamping and flipping robotic arm is in use, the servo motor is started, which drives the threaded column to rotate. The rotation of the threaded column drives the gear disk to rotate, and the rotation of the gear disk drives the movable plate to rotate. Under the restriction of the limit plate, the rotation of the movable plate will drive the clamping hand to firmly clamp the material, making operation convenient.

[0020] When this multi-station gripping and flipping robotic arm is in use, the gripper firmly holds the material, the gear disk disengages from the threaded area of ​​the threaded column, and the threaded column engages with the gear disk. The gear disk stops rotating, while the continuous rotation of the threaded column drives the fixed block to rotate. The rotation of the fixed block drives the extension plate to rotate, and the rotation of the extension plate drives the fixed plate to rotate, which in turn causes the support shell to rotate. The rotation of the support shell causes the material to rotate, thus flipping the material. It is easy to use. Attached Figure Description

[0027] like Figures 1-4As shown, this utility model discloses a multi-station gripping and flipping robotic arm robot, including a base 1, a multi-station operating table 10 adapted to a robotic arm mechanism 2, and an operating area 11 on the inner side of the multi-station operating table 10. It also includes a robotic arm mechanism 2 disposed above the base 1, the robotic arm mechanism 2 including a support base 24, and a gripping component 25 for gripping and flipping materials disposed inside the support base 24. The gripping component 25 includes a hollow sleeve 250 fixedly connected to the support base 24, and a rotating part is rotatably disposed inside the hollow sleeve 250. The rotating sleeve 251 has a support shell 252 fixedly mounted on it, and a movable plate 253 is rotatably mounted inside the support shell 252. A clamping hand 254 is rotatably mounted inside the movable plate 253 and is used to clamp materials. A servo motor 257 located inside the rotating sleeve 251 is fixedly mounted inside the hollow sleeve 250, and a threaded post 256 is provided at the output end of the servo motor 257. A gear disk 255 is meshed on the threaded post 256 and is rotatably mounted inside the support shell 252 and fixedly connected to the movable plate 253.

[0028] A fixing block 258 is fixedly installed on the threaded column 256, and an extension plate 2580 is fixedly installed on the fixing block 258. A fixing plate 2581 is fixedly installed on the support shell 252. The fixing plate 2581 and the extension plate 2580 cooperate to drive the support shell 252 to rotate through the rotating sleeve 251. Through the linkage design of the fixing block 258, the extension plate 2580, and the fixing plate 2581, the power of the servo motor 257 is efficiently transmitted to the support shell 252. This structure, through rigid connection and meshing transmission, can precisely control the rotation angle of the rotating sleeve 251.

[0029] A base 20 is fixedly connected to the base 1, and a stabilizing seat 21 is fixedly installed on the base 20. A connecting arm 22 is rotatably installed above the stabilizing seat 21, and a connecting piece 23, which is fixedly connected to the support base 24, is rotatably installed at the end of the connecting arm 22 away from the stabilizing seat 21. The composite support structure formed by the base 20, the stabilizing seat 21, and the connecting arm 22 significantly improves the vibration resistance and load-bearing capacity of the robotic arm through a multi-point distributed load design, resulting in high stability. A connecting block 27 is fixedly installed on the connecting piece 23, and a telescopic rod 26 is rotatably installed on the connecting block 27. The end of the telescopic rod 26 away from the connecting block 27 is rotatably connected to the base 20. The hinge design of the telescopic rod 26 and the connecting block 27 gives the robotic arm mechanism 2 multi-degree-of-freedom motion characteristics. By dynamically adjusting the length of the telescopic rod 26, the path deviation caused by the swing of the connecting arm 22 can be compensated in real time, expanding the operating range of the robotic arm in narrow spaces or environments with many obstacles. It is particularly suitable for grasping and adjusting the posture of complex stacked materials in warehousing and logistics.

[0030] A fixing rod 259 is provided inside the support shell 252. A limiting plate 2590 is rotatably mounted on the fixing rod 259, and the limiting plate 2590 is rotatably connected to the clamping hand 254. The secondary constraint mechanism formed by the fixing rod 259 and the limiting plate 2590 realizes dynamic self-correction of the clamping state of irregular materials by synchronously following the rotation trajectory of the clamping hand 254.

[0031] Working principle: When using this multi-station gripping and flipping robotic arm, the servo motor 257 is started. The servo motor 257 drives the threaded column 256 to rotate, which in turn drives the gear disk 255 to rotate. The gear disk 255 then drives the movable plate 253 to rotate. Under the constraint of the limiting plate 2590, the rotation of the movable plate 253 drives the gripper 254 to firmly grip the material. When the gripper 254 firmly grips the material, the gear disk 255 disengages from the threaded area of ​​the threaded column 256, and the threaded column 256 engages with the gear disk 255, stopping the gear disk 255 from rotating. At the same time, the continuous rotation of the threaded column 256 drives the fixed block 258 to rotate, which in turn drives the extension plate 2580 to rotate. The rotation of the extension plate 2580 drives the fixed plate 2581 to rotate, causing the support shell 252 to rotate. The rotation of the support shell 252 drives the material to rotate, thus gripping and flipping the material, making it convenient to use.
