5. The nail sealing mechanism for liquid injection of cylindrical power batteries according to claim 4, characterized in that, The battery clamping and positioning mechanism includes a vertical plate, on which a battery-pressing cylinder and a linear guide rail are provided. The linear guide rail is connected to a sliding plate via a linear slider. The piston rod of the battery-pressing cylinder is connected to the sliding plate. The sliding plate is provided with a second linear guide rail, an upper gas spring, and a lower gas spring. The second linear guide rail is connected to the pressure plate via a second linear slider.

6. The nailing and sealing mechanism for injecting electrolyte into a cylindrical power battery according to claim 4, characterized in that, The position adjustment assembly includes an adjustment handwheel, on which a first pulley is provided, and on which a second mounting bracket is provided a second pulley. The second pulley and the first pulley are connected by a synchronous belt, and the battery clamping and positioning mechanism is connected to the synchronous belt by a connecting block.

7. The nail sealing mechanism for liquid injection of cylindrical power batteries according to claim 1, characterized in that, The nail supply mechanism includes a machine base, on which a hopper, a nail-picking robot, and a nail positioning mesh are provided. The hopper is mounted on a vibrator, and the nails vibrated down from the hopper fall onto the nail positioning mesh. The nail-picking robot picks up three nails at a time from the nail positioning mesh and places them on the nail platform.

8. The nail sealing mechanism for liquid injection of a cylindrical power battery according to claim 7, characterized in that, A camera is installed above the machine. The camera takes pictures of the glue nails on the glue nail mesh to determine the position of the glue nails, and sends the position information of the glue nails to the glue nail picking robot. The glue nail picking robot picks up the glue nails according to the position of the glue nails provided by the camera.

9. The nail sealing mechanism for liquid injection of the cylindrical power battery according to claim 7, characterized in that, The glue-removing robot includes an X-axis servo module, a Y-axis servo module, and a Z-axis servo module.
