DETAILED DESCRIPTION

[0016] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0017] like Figure 1-2As shown, the utility model provides a technical solution for a magnetic levitation grabbing and handling mechanism: comprising a pillar 1, a top seat 11 is arranged on the top of the pillar 1, and a linear motor 2 is installed on the top seat 11. Specifically, the working principle of the linear motor 2 is the same as that of the rotary motor. After the stator winding is connected to the three-phase alternating current, the energized coil will generate a magnetic field according to the magnetic effect of the current. This magnetic field and the magnetic field generated by the permanent magnet of the mover will synthesize a sinusoidal wave magnetic field moving along a straight line, that is, a traveling wave magnetic field, and the moving direction of the magnetic field is determined by the phase sequence of the three-phase alternating current. According to Lenz's law, when the moving metal plate is cut by the traveling wave magnetic field, an electromotive force will be induced and an electric current will be generated. The current will interact with the traveling wave magnetic field to generate an electromagnetic thrust, driving the moving part to move in a straight line along the direction of the moving magnetic field, or using the reaction force to drive the stator to move in the opposite direction. A moving seat 3 is installed at the moving end of the linear motor 2. Guide rails 21 are arranged on both sides of the linear motor 2, and a guide seat 22 adapted thereto is installed on the guide rails 21. The guide seat 22 is connected to the moving seat 3. A grabbing assembly is installed on the moving seat 3. The grabbing assembly includes a lifting motor 31. A lifting screw 32 is connected to the output end of the lifting motor 31. A nut seat is mounted on the outer surface of the lifting screw 32, and a material picking seat 33 is installed on the outer side of the nut seat. A clamping cylinder 34 is installed on the material picking seat 33, and a plurality of clamping jaws 35 are installed at the output end of the clamping cylinder 34.

[0018] In this embodiment, when in use, after the linear motor 2 is powered on, the traveling wave magnetic field generated drives the moving seat 3 to move horizontally along the top seat 11. When the lifting motor 31 is working, the lifting screw 32 and the nut seat cooperate to drive the material picking seat 33 and the clamping claw 35 to move up and down, thereby achieving accurate positioning and grasping of the workpiece. At the same time, the grasping component also includes a positioning ring 37 and a positioning sensor 38. The positioning ring 37 is used to perform preliminary positioning of the workpiece, and the positioning sensor 38 can sense the specific position of the workpiece, further improving the handling accuracy and efficiency.

[0019] The magnetic suspension grabbing and handling mechanism of the utility model realizes fast and accurate grabbing and handling of workpieces through the coordinated work of the linear motor 2 and the lifting motor 31. Compared with the traditional mechanical grabbing and handling mechanism, the utility model has higher working efficiency and handling accuracy, and can reduce energy consumption and environmental pollution, and has broad application prospects.

[0020] In addition, the magnetic levitation grabbing and handling mechanism of the utility model can also be customized and expanded according to actual needs. For example, multiple grabbing components can be added to achieve the simultaneous grabbing of multiple workpieces, or the grabbing and handling of workpieces of different shapes and sizes can be achieved by changing the structure of the grabbing components.

[0021] In summary, the magnetic levitation grabbing and handling mechanism of the utility model has the advantages of high efficiency, precision, energy saving, and environmental protection. It can be widely used in various automated production lines and logistics handling fields, providing strong support for the development of modern manufacturing industry.

[0023] In this embodiment, a plurality of positioning sensors 38 are arranged on the positioning ring 37, which can accurately sense and identify the position and state of the material picking seat 33, thereby ensuring the smooth progress of the entire work process. When the material picking seat 33 reaches the predetermined position, the positioning sensor 38 will respond quickly and transmit the signal to the control system, so that the device can accurately and quickly complete the material picking task, greatly improving the working efficiency and accuracy of the device.

[0024] like Figure 1-2 As shown, vertical guide rails 39 are arranged on both sides of the lifting screw 32 , and a matching vertical guide seat 40 is arranged outside the vertical guide rails 39 , and the vertical guide seat 40 is connected to the material taking seat 33 .

[0025] In this embodiment, vertical guide rails 39 are provided on both sides of the lifting screw 32, and these vertical guide rails 39 ensure the stable movement of the lifting screw in the vertical direction. The vertical guide rails 39 are provided with matching vertical guide seats 40 outside, and this design enables the vertical guide seats 40 to slide smoothly along the vertical guide rails 39, thereby achieving precise vertical motion control.
