Technical Field

[0001] The invention relates to the technical field of manipulators, and in particular to a manipulator used for loading and unloading materials on a full-automatic winding machine. Background Art

[0002] Traditional fully automatic winding machines often rely on manual operation during the loading and unloading process, which not only increases labor costs, but also reduces production efficiency and poses safety hazards.

[0003] In order to solve this problem, in recent years, the industry has begun to explore the use of automation technology to achieve automatic loading and unloading of winding machines. At present, although there are some automatic loading and unloading equipment on the market, these devices are often complex in structure, high in maintenance cost, and have limited adaptability to workpieces. Therefore, it is particularly important to develop a fully automatic loading and unloading manipulator for winding machines with simple structure, easy operation and strong adaptability.

[0004] When designing manipulators in the prior art, the gripping stability and adaptability of the mechanical claws are often ignored, resulting in slippage or unstable gripping when grasping workpieces of different shapes and sizes. In addition, the drive mechanism and control system design of some manipulators are not reasonable, resulting in the manipulator's inflexible movements and difficulty in achieving precise control. Summary of the invention

[0007] Furthermore, the mechanical claw includes a plurality of arc-shaped claw bodies, and the bottom of the arc-shaped claw bodies is provided with an arc-shaped groove adapted to the edge of the workpiece so as to better grasp the workpiece.

[0008] Furthermore, three arc-shaped claw bodies are provided and are respectively connected to the cylinder through a rotating frame. The three arc-shaped claw bodies are arranged along the circumference with the same radius to form an annular claw, thereby enhancing the grasping stability and adaptability.

[0009] Preferably, the cylinder is fixedly connected to the steering wheel through a fixing frame, the side of the fixing frame is connected to the steering wheel, and the bottom extends outward to form an L-shape as a whole. The cylinder is fixed at the bottom of the fixing frame to ensure the stability and reliability of the cylinder.

[0010] Furthermore, the cylinder is connected to the mechanical claw through a rotating frame, one end of the rotating frame is connected to the power output end of the cylinder, and the other end is connected to the mechanical claw, so as to realize the opening and closing actions of the mechanical claw.

[0011] In order to protect the cylinder and enhance its stability, a cylinder cover is arranged on the outside of the cylinder, the top of the cylinder cover is fixedly connected to the fixed frame, and the middle of the rotating frame is rotatably connected to the cylinder cover.

[0012] The advantages of the present invention over the prior art are: the present invention realizes the loading and unloading operation of the fully automatic winding machine and improves the working efficiency. The mechanical claw adopts an arc-shaped claw body design, and an arc-shaped groove adapted to the edge of the workpiece is provided at the bottom, which enhances the grasping stability and adaptability.

[0017] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “inside”, “outside”, “vertical” and “circumferential” are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] A robot arm of the present invention is further described in detail below with reference to the accompanying drawings.

[0020] Combined with Figure 1-3 The specific implementation process of a manipulator of the present invention is as follows:

[0021] A robot comprises a stroke crankshaft 1, a steering wheel 2, a cylinder 3, an induction switch 4 and a mechanical claw 5.

[0022] The stroke crankshaft 1 serves as a motion trajectory control component of the manipulator, and the steering wheel 2 is arranged on one side of the stroke crankshaft 1 . The steering operation of the manipulator is achieved by the rotation of the steering wheel 2 .

[0023] The cylinder 3 is fixedly connected to the steering wheel 2 through a fixing frame 9, the fixing frame 9 is connected to the steering wheel 2 at the side, and the bottom extends outward to form an L-shaped structure as a whole, and the cylinder 3 is fixed at the bottom of the fixing frame 9. This design not only ensures the stability of the cylinder 3, but also facilitates the driving operation of the cylinder 3.

[0024] The induction switch 4 is arranged on one side of the cylinder 3 and is used to detect the position or state of the workpiece. When the workpiece reaches the specified position, the induction switch 4 sends a signal to control the cylinder 3 to start or shut down, thereby realizing automatic operation.

[0025] The mechanical claw 5 includes three arc-shaped claw bodies 6, each of which has an arc-shaped groove 7 at the bottom thereof adapted to the edge of the workpiece. The arc-shaped claw body 6 is connected to the cylinder 3 via a rotating frame 8, and the three arc-shaped claw bodies 6 are arranged along the circumference with the same radius to form an annular claw. When the cylinder 3 is working, the rotating frame 8 drives the mechanical claw 5 to open or close, thereby grasping or releasing the workpiece.
