[0100] The provision of multiple diversion pipes 52 can allow hot air to enter the wind knife 31 more evenly, thereby making the wind knife 31 discharge air more evenly and achieving a better shaping effect on the film.

[0101] Furthermore, since the wind knife 31 can be raised and lowered on the frame 1, in order to ensure the normal lifting and lowering of the wind knife 31, the wind guide module 5 also includes a plurality of telescopic tubes (not shown in the figure), which are arranged one by one with the shunt tube 52, and the shunt tube 52 and the wind knife inlet are connected through the telescopic tube.

[0102] When the wind knife 31 needs to be controlled to rise and fall, the main lifting plate 331 rises and falls, thereby driving the auxiliary lifting plate 332 to rise and fall, and then the auxiliary lifting plate 332 drives the wind knife 31 to rise and fall. During the lifting and falling process of the wind knife 31, the air guide pipe 51 and the diverter pipe 52 are both fixed, and the telescopic pipe is extended and retracted to ensure the normal lifting and falling of the wind knife 31.

[0103] Furthermore, in this embodiment, the telescopic tube is a high temperature resistant corrugated telescopic tube.

[0104] The use of the air guide module 5 can make the pipeline length relatively short, reduce heat loss, and reduce the energy consumption of the hot air generating module 2.

[0105] Preferably, in this embodiment, the air guide pipe 51 is made of stainless steel. Stainless steel can reduce the aging and damage of the pipeline and improve the stability and reliability of the equipment.

A conveying mechanism is provided at each component placement position 41, and the conveying mechanism includes two relatively arranged conveyor belts 42. The extension direction of each conveyor belt 42 is consistent with the width direction of the component at the component placement position 41.

[0111] With such arrangement, the length direction of the component at the component placement position 41 is consistent with the extension direction of the wind knife 31, and the wind knife 31 shapes the adhesive film on the battery cell string in the long side direction. Compared with shaping in the width direction, the shaping time can be reduced by half in this embodiment.

[0112] Furthermore, the component placement module 4 also includes a component placement module rack 43, and the component placement position 41 is arranged on the component placement module rack 43. Projected along the vertical direction, the projection of the rack 1 at least partially covers the projection of the component placement module rack 43 to save the space occupied by the film molding equipment in the width direction.

[0113] The component placement module rack 43 is located below the rack 1 and below the hot air ejection module 3 .

[0114] Specifically, in this embodiment, when projected in the vertical direction, the projection of the rack 1 partially overlaps with the projection of the component placement module rack 43. Such an arrangement can save the space occupied by the film shaping equipment in the width direction.

[0115] Furthermore, the film shaping device further comprises a rotatable operating panel 6. Specifically, the rotatable operating panel 6 is fixedly mounted on a swing arm rotating support on the frame 1 via a connecting swing arm 61.

[0118] Exemplarily, in this embodiment, the working process of the film shaping device is as follows:

[0119] After the film is laid on the battery cell string, the battery cell string flows into the component placement position 41, and the hot air from the hot air generation module 2 flows to the wind knife 31, and the wind knife 31 is controlled to descend, and then the wind outlet angle of the wind knife 31 is continuously adjusted to complete the shaping of the film. After the shaping of the film is completed, the wind knife 31 is controlled to rise and reset, waiting for the next shaping operation.

[0120] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
