8. The automatic conversion and pressurizing clamping mechanism for a soft-pack battery tray according to claim 7, characterized in that: The linear motion motor assembly includes a linear drive motor, a fifth screw rod, a fifth screw rod nut and a clamping seat. The linear drive motor is installed and fixed on the lower plate surface of the connecting plate, and its driving end is connected to the fifth screw rod; The fifth screw rod is supported on the connecting plate through a socket; the fifth screw rod nut is threadedly connected to the fifth screw rod and is installed and fixed on the connecting plate; the socket is installed at the front end of the connecting plate and has a socket on it for supporting the fifth screw rod; when the linear drive motor rotates, it drives the fifth screw rod to rotate, thereby promoting the movement of the fifth screw rod nut and the connecting plate. Under the guidance of the linear slide rail, the connecting plate performs horizontal linear motion, and then moves the linear drive motor pressure assembly to stop close to the restraint tray; the rotational motion rotation drive motor assembly includes a rotational drive motor, a sleeve and a support seat; the rotational drive motor is installed and fixed on the upper plate surface of the connecting plate through the support seat, and a sleeve is installed at its pushing end; the sleeve is used to cooperate with the fifth screw rod of the restraint tray; when the rotational drive motor rotates, it drives the sleeve to rotate, thereby driving the fifth screw rod to rotate.

9. The automatic conversion and pressurizing clamping mechanism for a soft-pack battery tray according to claim 1, characterized in that: The battery tray includes a base, an outer frame and an inner lining, wherein the base is the bottom plate of the battery tray and is fixed to the outer frame; the outer frame has notches on two opposite sides for the soft-pack battery tabs to extend out; the inner lining is laid on the surface of the bottom and is provided with a plurality of slots for placing the soft-pack batteries, so that the soft-pack batteries can be placed vertically on the placement slots and the tabs of the soft-pack batteries can be kept extending out from the notches of the outer frame to the left and right or on the same side.

10. A method for converting and clamping a tray using the automatic conversion and pressurization clamping mechanism for a soft-pack battery tray according to any one of claims 1 to 9, the steps being: 1) Place the battery tray filled with soft-pack batteries in the transport area on the second floor of the rack, and then move it to the installation area of ​​the tray; 2) After the battery tray is installed in place, the grabbing unit is started, and the wide-pitch manipulator of the grabbing unit, under the action of the motor assembly and the lifting device, transfers the soft-pack battery from the battery tray to the battery variable-pitch guide assembly; 3) After the soft-pack batteries fall into the battery variable-pitch guide assembly, the battery variable-pitch guide assembly arranges them in an orderly manner; 4) After the soft-pack battery is adjusted, the grabbing unit is started, and the narrow-pitch manipulator of the grabbing unit, under the action of the motor assembly and the lifting device, transfers the soft-pack battery from the battery variable-pitch guide assembly to the restraint tray pressurizing assembly; 5) After the battery falls into the restraint tray, the motor pressurizing assembly is started, and the soft-pack batteries of the multiple restraint trays are pressurized and clamped.
