The fully automatic heavy-duty battery pack loading device according to claim 5, characterized in that, The push-pull mechanism (33) includes: The push-pull frame (331) is mounted on the third linear slide rail (346) via the second guide slider (332) and is fixedly connected to the transmission chain (344) via the chain clamp (333). The transmission chain (344) is used to drive the push-pull frame (331) to reciprocate along the length direction of the track support (342). An adapter plate (334) is disposed at one end of the push-pull frame (331) away from the drive component (341) and located on the side of the push-pull frame (331) near the battery accommodating cavity (311); A rotary cylinder (335) is disposed on one side of the adapter plate (334) near the push-pull frame (331) and is installed at both symmetrical ends of the adapter plate (334); A pull rod (336) is provided at both symmetrical ends on the side of the adapter plate (334) away from the push-pull frame (331). One end of the pull rod (336) passes through the adapter plate (334) and is connected to the transmission end of the rotary cylinder (335) through a coupling (337). A push-pull force sensor (338) is disposed between the adapter plate (334) and the push-pull frame (331). One end of the push-pull force sensor (338) is connected to the adapter plate (334), and the other end is connected to the push-pull frame (331). A plurality of battery push blocks (339) are also installed on the side of the adapter plate (334) away from the push-pull force sensor (338). The battery push blocks (339) are arranged with equal spacing.

7. The fully automatic heavy-duty battery pack loading device according to claim 6, characterized in that: The push-pull frame (331) is in the shape of an inverted triangle. The second guide slider (332) is symmetrically arranged at one end of the push-pull mechanism (33) away from the ground rail (10). A positioning column (50) is also installed on the side of the push-pull frame (331) near the adapter plate (334). The positioning column (50) is arranged on both sides of the push-pull force sensor (338). The adapter plate (334) has a positioning through hole (51) corresponding to the positioning column (50).

8. The fully automatic heavy-duty battery pack loading device according to claim 1, characterized in that: The robotic arm (20) is a six-axis robotic arm. A guide rail (11) is provided on the ground rail (10). A movable disk (12) is slidably installed on the guide rail (11). The robotic arm (20) is fixedly installed on the movable disk (12). A drive motor (13) is also installed on the movable disk (12). The drive motor (13) is used to drive the movable disk (12) to reciprocate along the length direction of the guide rail (11).
