With the development of new energy industries, batteries have been widely used in various fields. The battery may be various types of batteries, and may be, for example, a lithium ion battery (lithium ion secondary battery or lithium ion primary battery), a lithium sulfur battery, a sodium ion battery, or a magnesium ion battery, but is not limited thereto.

Illustratively, a battery may include a housing, an electrode assembly and an electrolyte sealingly disposed within the housing. The case is a structure capable of providing a closed space for the accommodation of the core assembly and the electrolyte, and may have various shapes such as a rectangular parallelepiped shape, a flat shape, and the like, but is not limited thereto. The cell assembly is a component for electrochemical reaction in the battery, and can comprise a positive plate, a negative plate and a diaphragm arranged between the positive plate and the negative plate. During the charge and discharge of the battery, metal ions in the electrolyte move between the positive plate and the negative plate.

In the production process of the battery, it is generally necessary to coat the outer surface of the battery with a protective film (for example, coat the outer surface of the case of the battery with a protective film) for insulating and protecting the battery, so as to increase the insulating performance between the battery and the battery or between the battery and other components, and in addition, the protective film can beautify the appearance of the battery. Therefore, the battery is generally coated by a coating machine (i.e., the coating machine coats the outer surface of the battery with a protective film), and the coating machine is a specific actuator of the coating machine for coating the battery.

In some cases, the coating device of the coating equipment generally includes many parts, such as a clamping mechanism for clamping the battery, a plurality of rollers for coating the surface of the battery with the protective film, and the like, and the protective film is sequentially coated on each surface of the battery through the matching of the parts, so that the number of processes is large, and the coating efficiency is low. Moreover, the coating device has more components, so that the structure is more complicated. In addition, after the surface of the battery is coated with the protective film, the protective film is easy to have defects such as wrinkles and bubbles, and the coating quality and the appearance of the battery are influenced.

Based on the above, in order to solve the technical problem that the film coating efficiency of the film coating device is low, the inventor designs a film coating device, wherein a first film coating piece, a lifting piece and a second film coating piece are arranged, the first film coating piece comprises a first film coating part and a second film coating part which are arranged at intervals along a first direction, and a containing space is formed between the first film coating part and the second film coating part; the lifting piece can move towards the accommodating space along a second direction perpendicular to the first direction so as to push the battery arranged on the arrangement part of the lifting piece and the protective film positioned on one side of the battery, which faces the accommodating space, into the accommodating space, so that the first film sticking part and the second film sticking part stick the protective film to a first surface and a second surface of the battery, which are opposite to each other; meanwhile, the protective film is tensioned through the first film pasting part and the second film pasting part, so that the protective film can be pasted on one surface of the battery between the first surface and the second surface, and the protective film can be pasted on three surfaces of the battery through one-time movement of the lifting piece; then, move near the lift through second pad pasting spare along first direction, locate the third face that the battery supported on the settling part with the protection film subsides to make four faces of circumference of battery all paste and be equipped with the protection film. Generally, the coating process of the battery is less, and the coating efficiency can be effectively improved. Moreover, the whole parts are fewer, the structure is simplified, and the reliability is improved. In addition, first pad pasting portion, second pad pasting portion and second pad pasting spare all can play and scrape the effect of leveling or pacifying the protection film, do benefit to and reduce the protection film and produce defects such as fold, bubble, can improve the diolame quality.

The coating device disclosed by the embodiment of the application can be applied to coating equipment so as to coat a protective film on the outside of a battery.

Next, a description will be given of a coating apparatus provided in an embodiment of the present application.

Referring to fig. 1 to 5, fig. 1 shows a schematic structural diagram of an encapsulation device 100 provided in some embodiments of the present application, fig. 2 shows a schematic structural diagram of a battery 200 provided in some embodiments of the present application, fig. 3 to 5 sequentially show a schematic structural diagram of a process of encapsulating the battery 200 shown in fig. 2 by the encapsulation device 100 shown in fig. 1, a process shown in fig. 4 follows the process shown in fig. 3, and a process shown in fig. 5 follows the process shown in fig. 4. The coating device 100 comprises a first coating member 10, a lifting member 20 and a second coating member 30, wherein:

the first film member 10 includes a first film portion 11 and a second film portion 12 spaced apart from each other in the first direction a, and an accommodating space 101 is formed between the first film portion 11 and the second film portion 12.

The elevation member 20 includes a seating portion 21 for supporting the battery 200, the seating portion 21 facing the accommodation space 101. The lifting member 20 can move toward or away from the accommodating space 101 along a second direction B perpendicular to the first direction a, and is used for pushing the battery 200 and the protective film 300 between the battery 200 and the first film-applying member 10 into the accommodating space 101, so that the first film-applying portion 11 and the second film-applying portion 12 respectively apply (i.e., attach) the protective film 300 to the first surface 201 and the second surface 202 of the battery 200, and the protective film 300 is applied to the fourth surface 204 of the battery 200 facing the accommodating space 101.

The second film sticking member 30 is positioned at one side of the elevation member 20. The second film application member 30 is movable toward or away from the elevating member 20 in the first direction a for applying (i.e., applying) the protective film 300 to the third face 203 of the battery 200 supported on the seating portion 21.

It should be understood that the battery 200 and the protective film 300 are not part of the capsule device 100, but are the objects of the capsule device 100, and are introduced for the convenience of understanding the aspects of the embodiments of the present application. The battery 200 may be of various types or shapes. In fig. 2, which schematically shows a case where the battery 200 has a rectangular parallelepiped shape, the battery 200 may include first and second opposing faces 201 and 202, and third and fourth opposing faces 203 and 204; first surface 201, fourth surface 204, second surface 202, and third surface 203 meet in order end to enclose the circumferential side surface of cell 200. The protective film 300 may be a protective film made of various materials, such as a protective film made of an insulating material (e.g., a film made of various polyester polymer materials), or a protective film made of other non-insulating materials, which is not limited in the embodiment of the present invention.

It is understood that the first film member 10 refers to a structure for attaching the protective film 300 to the outer surface of the battery 200; the first film portion 11 and the second film portion 12 are parts of the first film member 10, and each of the first film member and the second film member may be a structure capable of attaching the protective film 300 to the outer surface of the battery 200, and may be, for example, a scraper (e.g., a scraper blade, a scraper bar, a scraper block, etc.), a roller member, a brush member, or the like. The distance between the first and

second film portions

11 and 12 may be set according to the length, width, or thickness of the battery 200, so that when the battery 200 and the protective film 300 are pushed into the accommodating space 101, the first and

second film portions

11 and 12 can respectively act on the first and

second faces

201 and 202 of the battery 200 through the protective film 300 to attach the protective film 300 to the first and

second faces

201 and 202. The first direction a is parallel to a direction in which the first film portion 11 points to the second film portion 12 or a direction in which the second film portion 12 points to the first film portion 11.

The lifter 20 is a structural member capable of ascending movement or descending movement, and movement toward the accommodating space 101 may be regarded as ascending movement, and movement away from the accommodating space 101 may be regarded as descending movement. The movement of the elevating member 20 may be driven by a manual drive or a power mechanism, wherein the power mechanism may be, but is not limited to, an air cylinder, a ball screw mechanism, an electric push rod, etc. The elevating member 20 may have various shapes such as a plate-shaped structure, a column-shaped structure, a block-shaped structure, etc., but is not limited thereto, and may have other regular or irregular shapes as long as the installation portion 21 for installing the battery 200 can be provided. The mounting portion 21 is a part of the lifter 20, and is a structure having various shapes that can be used to mount or support the battery 200, and may be, for example, a surface structure, a plate structure, a block structure, or the like, but is not limited thereto. In the process that the lifting member 20 moves towards the accommodating space 101 along the second direction B to push the battery 200 and the protection film 300 into the accommodating space 101, the moving direction of the lifting member 20 is opposite to the gravity direction of the battery 200, which is beneficial for the battery 200 to be better supported on the mounting portion 21 of the lifting member 20.

The second film member 30 is a structure for attaching the protective film 300 to the outer surface of the battery 200, and may be a structure member having various shapes, such as a plate-shaped structure, a sheet-shaped structure, a scraper (e.g., a scraper bar, a scraper block, etc.), a roller member, a brush member, etc., but is not limited thereto. The movement of the second film member 30 may be driven by a manual driving or a power mechanism, wherein the power mechanism may be a cylinder, a ball screw mechanism, an electric push rod, etc., but is not limited thereto.

As can be seen from the above, in the encapsulation device 100 provided in the embodiment of the present application, the first film portion 11 and the second film portion 12 of the first film member 10 are disposed at intervals in the first direction a to form the accommodating space 101 therebetween; as shown in fig. 3 and 4, the lifting member 20 moves along a second direction B perpendicular to the first direction a, so as to push the battery 200 and the protective film 300 between the battery 200 and the first film member 10 into the accommodating space 101, and during the pushing process, the first film portion 11 and the second film portion 12 can respectively attach the protective film 300 to the first surface 201 and the second surface 202 of the battery 200; meanwhile, under the action of the first film sticking portion 11 and the second film sticking portion 12, the protective film 300 can be tensioned, and can be further stuck to one surface of the battery 200 between the first surface 201 and the second surface 202 (the surface is the surface of the battery 200 facing the accommodating space 101, namely the fourth surface 204), namely the protective film 300 can be stuck to three surfaces of the battery 200 simultaneously in the process that the lifting piece 20 pushes the battery 200 and the protective film 300 into the accommodating space 101, so that the film wrapping efficiency can be effectively improved. Then, as shown in fig. 4 and 5, the second film attaching member 30 moves along the first direction a, so that the portion of the protective film 300 located outside the accommodating space 101 can be attached to the third surface 203 of the battery 200 supported on the mounting portion 21, and thus the protective film 300 can be attached to four circumferential surfaces of the battery 200, and the film wrapping efficiency of the film wrapping apparatus 100 can be effectively improved.

Meanwhile, in the process that the lifting member 20 moves towards the accommodating space 101 so that the first film sticking portion 11 and the second film sticking portion 12 stick the protection film 300 to the first surface 201 and the second surface 202 of the battery 200, respectively, the first film sticking portion 11 and the second film sticking portion 12 can play a role in scraping or smoothing the protection film 300; in the process that the second film sticking member 30 moves toward the lifting member 20 to stick the protective film 300 to the third surface 203 of the battery 200, the second film sticking member 30 can also play a role in scraping or smoothing the protective film 300; thereby being beneficial to reducing the possibility of generating wrinkles and bubbles on the protective film 300 and improving the quality of the coating.

In this process, the lifting member 20 can only move in the first direction a away from the second film application member 30 to avoid the second film application member 30; the lifting member 20 can also move back to the accommodating space 101 along the second direction B after moving back to the second film sticking member 30 along the first direction a for a certain distance; the lifting member 20 may also be moved away from the receiving space 101 only in the second direction B.

In some embodiments, referring to fig. 7 to 9, fig. 8 and 9 are schematic structural diagrams sequentially illustrating a process of encapsulating a battery 200 by using an encapsulation device 100 according to still other embodiments of the present application, wherein the process shown in fig. 9 is subsequent to the process shown in fig. 8. Encapsulation device 100 also includes a third piece of film 70, third piece of film 70 being located on one side of elevator 20. The third film member 70 is movable toward or away from the first film portion 11 in the second direction B for attaching the edge of the protective film 300 to the first face 201 of the battery 200.

After the batteries 200 are transferred from the lifter 20 to the next process or the storage device after the coating is completed, the lifter 20 may move back to the side of the end of the conveyer 500 along the second direction B, i.e., to the initial position, away from the receiving space 101, and receive the batteries 200 conveyed by the conveyer 500 again, and thus, the process is repeated cyclically to coat the plurality of batteries 200 in sequence.

The coating machine 1000 is not limited to the case where the battery 200 is conveyed to the mounting portion 21 by the conveyor 500, and may clamp the battery 200 to the mounting portion 21 by a robot, a clamping mechanism, or the like.

In some embodiments, the coating apparatus 1000 may further include an unwinding device for unwinding the protective film 300. The protective film 300 passes between the first film application member 10 and the lifter 20.

Optionally, the film coating apparatus 1000 may further include a cutting mechanism configured to cut the protective film 300 unwound by the unwinding device. For example, after the protective film 300 is located between the first film attaching member 10 and the battery 200, the cutting mechanism cuts the protective film 300 to cut a protective film for covering one battery 200. The cutting mechanism may be various mechanisms capable of cutting the protective film 300, such as various mechanisms including a cutter.

Of course, in other embodiments, the unwinding device may not be provided, for example, the protective film 300 may be manually placed.

The embodiment of the application further provides a battery production line, which comprises the coating equipment 1000 of any embodiment.

It is understood that a battery production line is a route that is traveled during battery production or processing, and generally includes a plurality of processing devices that process the batteries 200, and a conveying device that conveys the batteries 200. For example, in addition to the encapsulation tool 1000, the battery production line can include at least one of a pole piece coating tool, a welding tool, an inspection tool, a conveyor line, a robot, and the like, but is not limited thereto; the processing devices can be communicated or connected through a conveying line or a mechanical arm.
