Description

Technical Field

[0001] This utility model relates to the field of battery packaging and automated assembly equipment, specifically to a large-scale energy storage insulating cover multi-functional blister box. Background Technology

[0002] With the rapid development of new energy technologies, power batteries and energy storage batteries are playing an increasingly crucial role in electric vehicles and large-scale energy storage systems. To meet the market's high demands for driving range before solid-state batteries achieve mass production, the mainstream approach is to increase the energy density of the module by increasing the number of individual battery cells and optimizing the series-parallel connection structure, thereby extending the overall driving range. After the battery cells are connected in series and parallel and welded to form a module, a PC vacuum-formed insulating cover must be installed on top to ensure the module's internal insulation, dustproofing, moisture protection, and structural stability.

[0003] Existing PC thermoforming insulating covers are typically formed in one piece using a vacuum thermoforming process, resulting in products with a thickness of only about 0.5mm. These covers are characterized by large volume, high flexibility, and relatively weak resistance to pressure and impact. During downstream logistics and transportation, these ultra-thin thermoformed covers are highly susceptible to warping, creases, or breakage due to stacking and vibration. Furthermore, on automated battery module sealing lines, the soft and easily deformable material often causes feeding jams and inaccurate positioning, severely impacting production cycle time and assembly accuracy, and even leading to poor module assembly or safety hazards.

[0004] Although various plastic containers are available on the market for the protection and transport of electronic components or rigid parts, there is currently no dedicated container structure for ultra-thin, micro-arc flexible, and large-sized PC blister covers. Existing packaging solutions often only meet the single requirement of transport protection and cannot be integrated with automated feeding systems. Manufacturers need to design or purchase two sets of equipment for logistics and production lines, resulting in high equipment investment and management costs, cumbersome operation, and an increased risk of cover damage and downtime due to frequent switching.

[0005] In summary, this utility model designs a large-scale energy storage insulating cover plate multifunctional blister box. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a multi-functional blister box for large-scale energy storage insulating covers. This box can provide reliable protection for battery PC blister covers during storage and long-distance transportation, reducing the scrap rate caused by damage. It can also be directly connected to automated production lines for battery module sealing, enabling efficient feeding, precise positioning, and rapid release. This significantly improves production cycle time and product qualification rate, while reducing overall enterprise costs.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a large-scale energy storage insulating cover multifunctional blister box, including a blister box body, on which two insulating cover contour cavities are provided. A PC blister insulating cover is placed inside the insulating cover contour cavity, and a lithium mica sheet is covered on the PC blister insulating cover. The inner surface of the insulating cover contour cavity is provided with reinforcing ribs to prevent stacking and collapse. Positive and negative electrode markings are provided on both sides of the reinforcing ribs. A product model marking area is also provided on the front edge of the blister box body. A product error-proof indicator is provided between the two insulating cover contour cavities.

[0008] Preferably, the stacking support opening at the bottom of the blister box body adopts a negative draft angle.

[0009] Preferably, the thickness of the blister box body is 1mm.

[0010] Preferably, the insulating cover plate is provided with an exhaust groove on the side of the cavity.

[0011] Preferably, a foolproof corner is provided at one corner of the blister box body.

[0012] The beneficial effects of this utility model are as follows: This utility model has a reasonable structural design, adopts 1mm PET blister molding, achieves high-precision positioning through contoured cavity + 0.5mm anti-sway gap, integrates reinforcing ribs to prevent collapse, lithium mica sheet insulation protection, stacking and inverted design and foolproof marking, and has mechanical strength, operational safety and automation adaptability. It can be reused and optimizes energy storage assembly efficiency. Attached Figure Description
