Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm with an adjustment mechanism. Background Technology

[0002] In today's industrial automation and many cutting-edge technology fields, robotic arms play a crucial role. From efficient and precise material handling and parts assembly on industrial production lines to delicate surgical assistance in the medical field, and to the detection of complex environments in scientific research, robotic arms have greatly improved production efficiency due to their reprogrammable and multi-degree-of-freedom motion characteristics.

[0003] Currently, common robotic arms adopt joint-type, rectangular coordinate, and cylindrical coordinate configurations in their structural design. In terms of drive methods, motor drive has become the mainstream due to its advantages of fast response speed and high control precision.

[0004] However, the adjustment mechanism of traditional robotic arms is often relatively simple in structure, making it difficult to achieve flexible adjustment in multiple dimensions and with high precision. It is also inconvenient to flexibly pick up and place workpieces and monitor the grasping screen in real time. The function of the robotic arm itself needs to be enhanced. In view of this, we propose a robotic arm with an adjustment mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a robotic arm with an adjustment mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A robotic arm with an adjustment mechanism includes a base plate, a base frame fixedly mounted at one top end of the base plate, a fixing frame fixedly mounted at the other top end of the base plate, a protective shell disposed outside the fixing frame, a display screen sleeved inside the protective shell, and an adjustment assembly disposed at the top of the base plate, the adjustment assembly including: The first servo motor is fixedly installed inside the base frame. A rotating frame is fixedly installed at the output end of the first servo motor. A second servo motor is fixedly installed inside the rotating frame. The output end of the second servo motor is fixedly connected to one end of a double-headed U-shaped frame. The output end of a third servo motor is fixedly installed at the other end of the double-headed U-shaped frame. The inner wall of one end of a swing frame is fixedly installed on the outer wall of the third servo motor. The fourth servo motor has an output end fixedly installed at the other end of the swing frame, an inner wall of one end of the end frame fixedly installed on the outer wall of the fourth servo motor, a fifth servo motor fixedly installed on the inner wall of the other end of the end frame, and a connecting frame fixedly installed at the output end of the fifth servo motor. The sixth servo motor is fixedly installed on the outer wall of the connecting frame. A gear plate is fixedly installed on the output end of the sixth servo motor. There are two sets of gear plates. The gear plate at the end away from the sixth servo motor is rotatably installed inside the connecting frame, and the two sets of gear plates mesh with each other. A gripper is hingedly installed on the gear plate. A hinge rod is hinged between the gripper and the connecting frame. The gripper is provided with anti-slip texture. An asynchronous motor is fixedly installed on the inner wall of the end frame. A camera bracket is fixedly installed on the output end of the asynchronous motor. A camera body is fixedly installed inside the camera bracket.

[0007] In a further embodiment, the mounting bracket is provided in two sets to better accommodate the display screen.

[0008] In a further embodiment, the grippers, hinge rods, and anti-slip textures are provided in two sets for better workpiece handling.

[0009] In a further embodiment, an auxiliary component is provided on the outside of the base frame. The auxiliary component includes a shelf. Two sets of fixed frames are fixedly installed with shelf, which is L-shaped and has a protective shell placed on it.

[0010] In a further embodiment, an L-shaped plate is fixedly installed on the top outer wall of the shelf, a rotating rod is fixedly installed on the L-shaped plate, a locking block is rotatably installed on the outside of the rotating rod, a fixing block and a limiting block are fixedly installed on the outer wall of the L-shaped plate, ball-head blocks are rolled inside the fixing block and the locking block, two sets of ball-head blocks are provided, a spring rod is fixedly installed between the two sets of ball-head blocks, and a moving block is fixedly installed on the top outer wall of the protective shell, the arc-shaped outer wall of the moving block slides against the arc-shaped outer wall of the locking block, so that the two can be smoothly locked together.

[0011] In a further embodiment, a handle is fixedly installed on the outer wall of the card block to facilitate active rotation of the card block.

[0012] In a further embodiment, a protective cover is fixedly installed on the top of the base plate.

[0013] Compared with the prior art, this utility model provides a robotic arm with an adjustment mechanism, which has the following beneficial effects: 1. This robotic arm with an adjustment mechanism enhances its functionality by incorporating an adjustment assembly. Activating the first servo motor rotates the rotating frame, the second servo motor rotates the double-headed U-shaped frame, the third servo motor rotates the swing frame, the fourth servo motor rotates the end frame, the fifth servo motor rotates the connecting frame, and the sixth servo motor causes two sets of gear plates to rotate in opposite directions. This, combined with the hinge rod, causes two sets of grippers to move in opposite directions. Anti-slip textures further facilitate workpiece handling. An asynchronous motor activates the camera bracket, which rotates the camera body, thereby increasing the robotic arm's freedom of movement and facilitating monitoring of the gripping end, ultimately enhancing the robotic arm's functionality.

[0014] 2. This robotic arm with an adjustment mechanism, in order to better adjust the robotic arm body, uses auxiliary components to place the bottom of the protective shell on the placement plate, thereby initially placing the display screen. During this process, the arc-shaped outer wall of the moving block will press against the arc-shaped outer wall of the locking block, causing the locking block to rotate around the pivot point. This, in conjunction with the fixing block and two sets of ball joints, causes the spring rod to compress and deform. When the protective shell is close to the placement plate, the moving block no longer presses against the locking block. The spring rod recovers its deformation and releases elastic potential energy, allowing the moving block and the locking block to engage. The limiting block constrains the movement stroke of the locking block. Combined with the handle, it is easy to actively rotate the locking block again, thus facilitating the fixing of the display screen and making it easy to adjust the setting parameters of the robotic arm body through the touch display screen.

[0022] In one embodiment of this utility model, an auxiliary component 5 is provided on the outside of the base frame 2. The auxiliary component 5 includes a shelf 51. The shelf 51 is fixedly installed on the outside of two sets of fixed frames 3. The shelf 51 is L-shaped. A protective shell 31 is placed on the shelf 51. In addition, an L-shaped plate 52 is fixedly installed on the outer wall of the top of the shelf 51. A rotating rod 53 is fixedly installed on the L-shaped plate 52. A locking block 54 is rotatably installed on the outside of the rotating rod 53. A fixing block 55 and a limiting block 58 are fixedly installed on the outer wall of the L-shaped plate 52. Ball head blocks 56 are rolled inside both the fixing block 55 and the locking block 54. Two sets of ball head blocks 56 are provided. A spring rod 57 is fixedly installed between the two sets of ball head blocks 56. A moving block 59 is fixedly installed on the outer wall of the top of the protective shell 31. The arc-shaped outer wall of the moving block 59 slides against the arc-shaped outer wall of the locking block 54, so that the two can be smoothly locked. In addition, a handle 510 is fixedly installed on the outer wall of the locking block 54 to facilitate active rotation of the locking block 54.

[0023] In this embodiment, the bottom of the protective shell 31 is placed on the shelf 51 to initially position the display screen 32. During this process, the arc-shaped outer wall of the movable block 59, which is fixedly installed on the top outer wall of the protective shell 31, presses against the arc-shaped outer wall of the locking block 54, causing the locking block 54 to rotate around the rotating rod 53. When the locking block 54 rotates, the spring rod 57 is compressed and deformed by the internally rolled ball head block 56, in conjunction with the fixed block 55 and another set of ball head blocks 56. When the protective shell 31 is pressed against the shelf 51, the movable block 59 no longer presses against the locking block 54. When the spring rod 57 recovers its deformation and releases its elastic potential energy, it pushes the locking block 54 to reset, so that the moving block 59 and the locking block 54 are engaged, thus fixing the display screen 32. The limiting block 58 restricts the movement of the locking block 54 and prevents it from rotating excessively. If the display screen 32 needs to be adjusted again, the locking block 54 can be actively rotated by the handle 510 fixedly installed on the outer wall of the locking block 54 to release the engagement and reposition the display screen 32, thus facilitating the fixing of the display screen 32 and facilitating the adjustment of the setting parameters of the robotic arm body by touching the display screen 32.
