Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production, and in particular to an automatic packaging device for soft-pack lithium batteries and a production line thereof. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive and negative electrode materials and uses a non-aqueous electrolyte solution. Among them, lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use a non-aqueous electrolyte solution. Lithium ion batteries generally use lithium alloy metal oxides as the positive electrode material, graphite as the negative electrode material, and use a non-aqueous electrolyte. Lithium ion batteries do not contain metallic lithium and are rechargeable.

[0003] Soft-pack lithium batteries are a type of lithium battery, usually referring to lithium batteries whose outer shell is encapsulated by aluminum-plastic composite film. Soft-pack lithium batteries have the characteristics of light weight and high safety. When safety hazards occur in soft-pack lithium batteries, since the outer shell is encapsulated by aluminum-plastic composite film, only bulging and rupture will occur, and no violent explosion will occur.

[0004] The existing soft-pack lithium battery production process requires that the aluminum-plastic film be cut to the required specifications and that the aluminum-plastic film be pressed into shape. During the pressing process, a cell film groove is formed on the surface of the aluminum-plastic film to facilitate the subsequent placement of the battery cell inside the cell film groove, and the aluminum-plastic film is folded in half so that the aluminum-plastic film completely wraps the battery cell in the cell film groove, and finally the aluminum-plastic film is sealed and packaged. The existing soft-pack lithium battery production process mostly requires manual loading and manual folding. The manual loading method cannot ensure that the position of the aluminum-plastic film and the battery cell is consistent during continuous production, and the manual folding method cannot ensure that the aluminum-plastic film is folded along the center line. If the folding line is offset, the battery production quality will be affected, the battery cell will be easily damaged, and the packaging of the aluminum-plastic film cannot be guaranteed. Therefore, manual loading and manual folding not only affect the work efficiency, but also affect the production quality because the placement position and the folding position cannot be ensured.

[0005] Reference patent application number is "CN109216593B", and the patent name is "A soft-pack lithium battery aluminum-plastic film packaging equipment and aluminum-plastic film automatic packaging process" Chinese invention patent. The technical solution discloses "A soft-pack lithium battery aluminum-plastic film packaging rolling machine and aluminum-plastic film packaging rolling method, including a supporting base plate, a placement rack, a pressure branch chain and a flattening device. A placement rack is installed on the upper end surface of the middle part of the support base plate, and a square groove is provided on the rear side of the right end of the placement rack. A pressure branch chain is installed on both the front and rear ends of the support base plate, and the pressure branch chain is located on the outside of the placement rack. The flattening device is installed on the top of the left end of the placement rack; the flattening device includes a flattening support Plate, flattening position push rod, flattening bracket, flattening adjustment plate, flattening sliding column, height push rod, smoothing plate, positioning mechanism and rolling mechanism". Although this technical solution can effectively solve the problems of displacement of the rotation point of the aluminum-plastic film when folding and deviation of the positions of the left and right ends of the aluminum-plastic film when packaging, this technical solution cannot realize the automatic and smooth folding action of the battery aluminum-plastic film and the smooth placement action of the battery cell, and the battery cell may be damaged when the aluminum-plastic film is rolled, thereby affecting the battery production quality. In addition, this technical solution can only realize the packaging production of a single battery aluminum-plastic film and battery cell at a single station, affecting production efficiency.

[0047] Embodiment 1, in order to realize automatic packaging production of soft-pack lithium batteries, in the packaging process of soft-pack lithium batteries, it is necessary to place the battery cells inside the battery cell film groove of the aluminum-plastic film, and fold the aluminum-plastic film with the battery cells in half to realize that the aluminum-plastic film completely wraps the battery cells. In order to realize the above actions automatically and improve production efficiency, in this embodiment: a feeding plate 1, a core swinging device 2, a film placing device 3, a flipping device 4, and a heat sealing device 5 are provided; the flipping device 4 is slidably arranged on the outside of the feeding plate 1, and the heat sealing device 5 is also adjacent to the flipping device 4.

In order to control the moving range of the flipping device 4, the swing core device 2 and the film placing device 3 are both located directly above the flipping device 4. When the moving mechanism 6 drives the flipping device 4 to be aligned with the film placing device 3, the aluminum-plastic film to be packaged can be placed on the flipping device 4 through the film placing device 3, and when the moving mechanism 6 drives the flipping device 4 to be aligned with the swing core device 2 again, the battery cell to be packaged can be placed on the flipping device 4 through the swing core device 2, and the aluminum-plastic film can be automatically folded in half by the flipping device 4 so that the aluminum-plastic film completely wraps the battery cell, and the flipping device 4 is moved again close to the heat sealing device 5 by the moving mechanism 6, and the edge of the aluminum-plastic film wrapped with the battery cell is automatically heat-sealed by the heat sealing device 5, thereby achieving the action of automatically packaging and producing soft-pack lithium batteries and improving production efficiency.

[0048] It should be noted that, in order to realize the automatic movement of the soft-pack lithium battery at the heat sealing station to the next station, in this embodiment: the material moving device 7 includes a linear moving module 71 and a mounting vertical plate 72, one side of the mounting vertical plate 72 is set on the power output end of the linear moving module 71, and a pressing mechanism 721 is set on the other side of the mounting vertical plate 72, by arranging a movable horizontal plate 722 on the power output end of the pressing mechanism 721, and by arranging a plurality of material moving suction plates 721 on the outside of the movable horizontal plate 722. 23, so that one side of the material transfer suction plate 723 faces the heat sealing device 5, the installation vertical plate 72 is driven by the linear moving module 71, and the movable horizontal plate 722 is driven to move closer to or away from the heat sealing station by the pressing mechanism 721.

[0050] It should be noted that, in order to ensure that the two side edges of the aluminum-plastic film are flush with the two side edges of the discharge suction plate 43 when the aluminum-plastic film is taken out, a trimming device 9 is provided directly above the feeding plate 1, and the trimming device 9 is aligned with the film discharge device 3. The trimming device 9 includes two trimming side plates 91, and the two trimming side plates 91 are positioned correspondingly. When the film discharge device 3 takes the material on the feeding plate 1 and moves it to the turning device 4, the aluminum-plastic film to be packaged can be driven through the trimming device 9, and the two side edges of the aluminum-plastic film are trimmed by the two trimming side plates 91, so as to ensure that the edges to be sealed are flush after the aluminum-plastic film is folded in half during subsequent edge sealing.
