The existing battery string film pasting mode needs to be provided with film pasting equipment and battery string carrying equipment, and the size and cost of the equipment are likely to be increased. In addition, in order to prevent the film sticking apparatus and the battery string carrying apparatus from interfering, a long waiting time is required to be set between the film sticking operation and the carrying operation, resulting in a low film sticking efficiency.

Therefore, the application provides a double-sided synchronous film pasting device for a battery string, which can synchronously apply films to the upper surface and the lower surface of the battery string from the upper side and the lower side, thereby reducing the cost of the device and improving the film pasting efficiency.

As shown in fig. 1, the battery string double-sided synchronous film laminating device in the embodiment of the application comprises a battery string feeding and conveying mechanism 1, a first adhesive film feeding mechanism 2, a second adhesive film feeding mechanism 3, a pressure-bearing mechanism 4, a film laminating mechanism 5 and a blanking and conveying mechanism 6, wherein:

The first adhesive film feeding mechanism 2 is configured to transfer a first adhesive film with a predetermined length between the pressure-bearing mechanism 4 and the film attaching station, and the second adhesive film feeding mechanism 3 is configured to transfer a second adhesive film with a predetermined length between the film attaching station and the film attaching mechanism 5.

The pressure-bearing mechanism 4 is configured to press the first adhesive film upwards to the lower surface of the battery string at the film pasting station, and the film pasting mechanism 5 is configured to press the second adhesive film downwards to the upper surface of the battery string so as to attach the first adhesive film and the second adhesive film to the upper surface and the lower surface of the battery string respectively.

The film sticking mechanism 5 is also configured to transfer the battery string with the adhesive film attached to the blanking conveying mechanism 6.

The discharging and conveying mechanism 6 is configured to convey the received battery string to the next process.

In order to enable those skilled in the art to more clearly understand the technical solution of the present application, a film pasting process of the battery string double-sided film pasting device according to an embodiment of the present application will be described in more detail below with reference to fig. 6.

As shown in fig. 6 (a), first, the battery string feeding and conveying mechanism 1 conveys the battery string 10 to be film-pasted to the film pasting station. Then, the first adhesive film feeding mechanism 2 transfers the first adhesive film 20 with a predetermined length between the pressure-bearing mechanism 4 and the film pasting station, and the second adhesive film feeding mechanism 3 transfers the second adhesive film 30 with a predetermined length between the film pasting station and the film pasting mechanism 5.

As shown in fig. 6 (b), the pressure-bearing mechanism 4 is lifted upward, and during the lifting process, it contacts and holds the first adhesive film 20, and then holds the battery string 10 on the battery string feeding and conveying mechanism 1.
