[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a permanent magnet manipulator that is easy to maintain, and has the following beneficial effects: 1. This type of permanent magnet robot arm, which is easy to maintain, replaces the traditional bolt connection method by using a plug-in and snap-fit ​​connection between the connection structure and the robot arm connecting frame. During installation, it is only necessary to insert the plug plate into the limiting plug slot and use the limiting structure to automatically lock it. During disassembly, the snap-fit ​​can be released with a simple operation. It eliminates the tedious bolt tightening steps, making the disassembly and assembly of the electro-permanent magnet robot arm simple and fast, and reducing the time cost of inspecting, replacing or maintaining this component.

[0013] 2. This type of permanent magnet robot, which is easy to maintain, has a limiting insertion groove in its connection structure that effectively limits the left and right sides of the insertion plate, ensuring the stability of the connection in the horizontal direction. At the same time, the locking pin in the limiting structure is firmly locked into the locking hole of the insertion plate under the continuous action of the helical spring, providing a reliable axial locking force. This effectively prevents loosening or falling off that may occur due to vibration or load changes during equipment operation, ensuring the stability and safety of the robot during operation.

[0014] 3. This type of permanent magnet manipulator, which is easy to maintain, innovatively incorporates drag-reducing steel balls in its limiting structure. During the insertion of the insertion plate, the drag-reducing steel balls form rolling friction with the surface of the insertion plate, which reduces the resistance and friction loss during insertion compared to traditional sliding friction. This not only makes the insertion operation more effortless and smoother, but also reduces wear on the surfaces of the insertion plate and the rear fixing plate, extends the service life of key components, and improves the durability of the equipment.
