Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and in particular relates to a shaping device for soft-pack arc-shaped batteries. Background Technology

[0002] With the continuous upgrading and iteration of electronic products, the market has placed higher demands on the appearance and performance of batteries. Traditional square and cylindrical batteries can no longer meet the needs of some emerging electronic products for thinner, smaller, and more irregularly shaped batteries. In recent years, pouch curved batteries have gradually become an ideal choice for wearable devices, smart homes, medical electronics and other fields due to their advantages such as strong plasticity, high energy density and good safety.

[0003] However, the manufacturing process of pouch curved batteries still faces many challenges. Insufficient edge width is one of the key factors restricting their performance and reliability. To increase the edge width, existing manufacturing processes typically fold the edge towards the back of the battery. However, this folding method easily leads to poor fit at the fold, and because the battery's head and tail are relatively rigid, problems such as a wider head and tail than the middle, wrinkles, and bubbles can easily occur after folding, affecting the battery's appearance and performance. To solve this problem, shaping fixtures are usually needed to reshape the folded battery. However, existing battery shaping equipment mainly focuses on square and cylindrical batteries, and these devices typically use planar pressing or rolling methods, suitable for batteries with regular shapes. Due to the unique curved structure of curved batteries, existing shaping equipment cannot be directly applied.

[0004] Therefore, developing a dedicated shaping device for curved batteries to address the gaps and deficiencies in existing technologies is of great significance for improving the production efficiency of curved batteries, ensuring product quality, and promoting their industrial application. Utility Model Content

[0005] The purpose of this invention is to provide a shaping device for soft-pack arc-shaped batteries, which solves problems such as poor fit at the folded edge, wide head and tail and narrow middle, wrinkles and air bubbles caused by the back folding method of arc-shaped batteries.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a soft-pack arc-shaped battery shaping device, comprising: a lower positioning block, an upper shaping block, a width shaping block, a horizontal mounting base, a vertical mounting base, a vertical elbow clamp, and a horizontal elbow clamp. The vertical elbow clamp is mounted on the vertical mounting base, and the vertical mounting base is fixed on the horizontal mounting base. The upper shaping block is mounted on the movable end of the vertical elbow clamp. The upper shaping block has a first outwardly convex arc surface facing the arc-shaped positioning groove on the lower positioning block. The lower positioning block is mounted on the horizontal mounting base, and the horizontal elbow clamp is mounted on the horizontal mounting base and facing the lower positioning block. The width shaping block is mounted on the movable end of the horizontal elbow clamp, and the width shaping block is located on the side of the arc-shaped positioning groove. In this device, the battery is placed in an arc-shaped positioning groove. The horizontal elbow clamp pushes the width shaping block to move horizontally, so that it fits against and clamps the side of the arc-shaped battery, thereby clamping and shaping the arc-shaped battery in the width direction. At the same time, the vertical elbow clamp pushes the upper shaping block to move downward in the vertical direction, thereby achieving arc surface shaping.

[0007] Preferably, the lower positioning block further includes a vertical plane and a limiting step. In this device, the vertical plane is used to fit tightly against the arc-shaped battery, and the limiting step is used to limit the extreme positions when the width shaping block moves.

[0008] Preferably, the width of the limiting step is equal to the width of the upper shaping block, and both are equal to the width of the arc-shaped battery, ensuring that the performance of the arc-shaped battery is not affected after shaping and that the width meets the requirements.

[0009] Preferably, both the first convex arc surface and the concave arc surface of the arc-shaped positioning groove are matched with the curvature of the arc-shaped battery surface.

[0010] Preferably, the horizontal mounting base is further provided with a guide groove for the width shaping block to slide through.

[0011] Preferably, the width shaping block has a second convex arc surface that matches the guide groove. The guide groove ensures the stability and reliability of the width shaping block's horizontal movement.

[0012] Preferably, the curvature of the guide groove is greater than that of the arc-shaped positioning groove, and together with the limiting step, it can achieve better fit and compression between the width shaping block and the side of the battery.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] I. This device achieves the external shaping of arc-shaped batteries by setting up a horizontally moving battery width shaping block in conjunction with the arc-shaped groove on the lower positioning block and the upper shaping block of the battery with an outwardly convex arc surface.

[0015] Second, the arc-shaped groove of the lower positioning block and the convex arc surface of the upper shaping block of this device can be varied according to the radius and arc length requirements of different battery models, especially for arc-shaped batteries with different curvatures such as small radius and large arc, which significantly improves the versatility and applicability of the device.

[0016] Third, the device described in this patent has a simple structure and is easy to manufacture. It can be designed as a simple manual tool or integrated into automated equipment. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the specific implementation of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixed connection," and "fixed connection" should be interpreted broadly.

Without departing from the principle of this utility model, several improvements and modifications can be made, and these improvements and modifications should also be considered within the protection scope of this utility model.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a soft-pack arc-shaped battery shaping device includes: a lower positioning block 1, an upper shaping block 2, a width shaping block 3, a horizontal mounting base 4, a vertical mounting base 5, a vertical elbow clamp 6, and a horizontal elbow clamp 7. The vertical elbow clamp 6 is mounted on the vertical mounting base 5, and the vertical mounting base 5 is fixed on the horizontal mounting base 4. The upper shaping block 2 is mounted on the movable end of the vertical elbow clamp 6. The upper shaping block 2 has a first outwardly convex arc surface 21 facing the arc-shaped positioning groove 11 on the lower positioning block. The lower positioning block 1 is mounted on the horizontal mounting base 4. The horizontal elbow clamp 7 is mounted on the horizontal mounting base 4 and faces the lower positioning block 1. The width shaping block 3 is mounted on the movable end of the horizontal elbow clamp 7, and the width shaping block 3 is located on the side of the arc-shaped positioning groove 11. In this device, the battery is placed in an arc-shaped positioning groove. In the horizontal direction, the width shaping block is pushed to move horizontally by a horizontal elbow clamp, so that it fits and clamps against the side of the arc-shaped battery, thereby achieving clamping and shaping of the arc-shaped battery in the width direction. At the same time, in the vertical direction, the setting of the vertical elbow clamp can achieve pre-compression and compression shaping of the inner arc surface of the arc-shaped battery, and finally achieve the shaping of the arc-shaped battery.

[0029] like Figure 4 and Figure 5 As shown, specifically, the horizontal mounting base 4 in this case is also provided with a guide groove 41 for the width shaping block 3 to slide through. The curvature of the guide groove 41 matches the second convex arc surface 31 at the bottom of the width shaping block 3. The guide groove enables the stability and reliability of the width shaping block's movement in the horizontal direction.

[0030] Specifically, for example Figure 2 and Figure 5As shown, the lower positioning block 1 in this case also includes a vertical plane 12 and a limiting step 13. The width of the limiting step 13 is equal to the width of the upper shaping block 2, and both are equal to the width of the arc-shaped battery. Furthermore, the curvature of the guide groove 41 is greater than the curvature of the arc-shaped positioning groove 11. With this design, when the width shaping block slides across the guide groove and approaches the arc-shaped battery, the limiting step 13 can limit the extreme position of the width shaping block 3 when it moves, so as to achieve better fit and pressing between the width shaping block and the side of the battery. At the same time, it ensures that the performance of the battery is not affected after shaping and that the width meets the requirements.

[0031] like Figure 6 and Figure 7 As shown, the working principle of this device is as follows: First, the arc-shaped battery 8 is placed in the arc-shaped positioning groove, so that one side of the arc-shaped battery is aligned with the vertical plane of the lower positioning block. Then, the vertical elbow clamp is pushed in the vertical direction to move the upper shaping block downward, so that the first convex arc surface of the upper shaping block contacts the inner arc surface of the battery but does not press it tightly, completing the pre-compression of the arc surface. Next, the horizontal elbow clamp is pushed to move the width shaping block in the horizontal direction to the limiting step, so that it is aligned with and clamped with the other side of the arc-shaped battery, completing the shaping in the width direction. Finally, the vertical elbow clamp is pushed again to move the upper shaping block downward, so that it is tightly aligned with the inner arc surface of the arc-shaped battery, completing the pressing and shaping of the arc surface. The pressing process of the upper shaping block of this device includes two stages: pre-compression and final pressing. Pre-compression is used to prevent the battery from flipping, and final pressing is used to ensure that the arc surface of the arc-shaped battery is tightly aligned, which can achieve the pressing and shaping of arc-shaped batteries with a center angle of less than 180°.

[0032] It should be noted that this device can also be equipped with an integrated intelligent control system to adjust the motion parameters and duration parameters of the width shaping block and the upper shaping block in real time. This allows for precise control of key parameters such as shaping pressure and time, meeting the shaping needs of batteries of different specifications and ensuring stable and reliable shaping results.
