The structural defect of the existing PPU manipulator is that the guide rail is directly connected to the material picking component. For example, the Chinese invention patent application number 202310726999.7 discloses an invention named a PPU handling manipulator, whose guide rail 5 is directly connected to the locking clamping device 7. This connection method only causes unstable force on the front end, and it is inconvenient to fix. Utility Model Content

[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings:

[0019] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have specific directions, be constructed and operated in specific directions. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 it can be indirectly connected 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 the specific circumstances.

[0021] like Figures 1 to 5 As shown, a clamping load connection structure of a PPU manipulator includes a load connection block 1 and a cover plate 2. A front groove 11 is provided at the rear of the load connection block 1. A guide rail 3 extends from a PPU manipulator body 4. The extension position of the guide rail 3 may be at the side or at the bottom. The load connection block 1 is installed in front of the extended part of the guide rail 3 and the front groove 11 is embedded in the front part of the guide rail 3. A rear groove 21 is provided in front of the cover plate 2. The cover plate 2 is installed behind the guide rail 3 and the rear groove 21 is embedded in the rear part of the guide rail 3. The front of the load connection block 1 is used for mounting The loading and unloading component (not shown) is provided with a plurality of clamping threaded holes 12 on the back of the load connection block 1, and the cover plate 2 is provided with a plurality of clamping mounting holes 22. The positions of the clamping threaded holes 12 correspond to the positions of the clamping mounting holes 22.
