Description

Technical Field

[0001] This utility model relates to the field of packaging and fixing technology, specifically a packaging and fixing device for soft-pack batteries. Background Technology

[0002] Currently, there are two major pain points in the heat-sealing process of soft-pack batteries (aluminum-plastic film packaging):

[0003] Positional misalignment: The battery cell is prone to slippage under pressure during the hot pressing process, resulting in misaligned sealing edges;

[0004] Aluminum-plastic film wrinkles: Uneven force application by traditional clamps can easily deform the aluminum-plastic film, leading to the risk of leakage. Utility Model Content

[0005] The purpose of this invention is to provide a soft-pack battery packaging and fixing device to solve the problems mentioned in the background art.

[0006] The technical solution of this utility model is: a soft-pack battery packaging and fixing device, including a base, on which a vacuum adsorption component is installed, and four pushing components arranged in a ring on the outside of the vacuum adsorption component, and multiple equidistant elastic limiting mechanisms are installed on the moving end of the pushing component.

[0007] The aforementioned components achieve the following effects: the base provides the mounting foundation, the vacuum adsorption component adheres to and fixes the pouch battery from the bottom, and at the same time, four ring-shaped pushing components drive the elastic limiting mechanism to approach the pouch battery synchronously from all sides. The elastic limiting mechanism forms a flexible clamping force against the side of the battery through elastic force. The adsorption force of the vacuum adsorption component and the ring synchronous clamping force of the elastic limiting mechanism form a three-dimensional fixing system, realizing the all-round positioning of the pouch battery during the heat-sealing process, effectively preventing the sealing edge from being skewed due to pressure slippage of the battery cell, and improving the sealing position accuracy.

[0008] Preferably, the vacuum adsorption component includes a vacuum adsorption seat mounted on the base, the vacuum adsorption seat having a negative pressure chamber for connecting to a negative pressure suction system, and the top of the negative pressure chamber having an adsorption hole extending to the outside of the vacuum adsorption seat.

[0009] The effect achieved by the above components is as follows: the negative pressure suction system is connected to the negative pressure chamber inside the vacuum adsorption seat, so that the adsorption hole generates a continuous and stable negative pressure suction force. When the soft pack battery is placed on the vacuum adsorption seat, the negative pressure in the negative pressure chamber acts directly on the bottom of the battery through the adsorption hole. The negative pressure adsorption force and the weight of the battery work together to form a tight fit, which realizes the firm fixation of the bottom of the battery, avoids the position displacement of the battery due to the bottom sliding during hot pressing, and increases the stability of the packaging process.

[0010] Preferably, the top of the adsorption seat is provided with a high-temperature resistant silicone pad, and the high-temperature resistant silicone pad has a groove that communicates with the adsorption hole.

[0011] The effects achieved by the above components are as follows: the high-temperature resistant silicone pad on the top of the adsorption base contacts the bottom of the soft-pack battery, and the groove of the high-temperature resistant silicone pad is connected to the adsorption hole to ensure that the negative pressure suction is effectively transferred to the battery. At the same time, the high-temperature resistance can adapt to the high-temperature environment of heat sealing. The elasticity of the silicone material can fill the tiny bumps and depressions on the bottom of the battery, enhance the adsorption and sealing performance, and the flexible contact reduces the squeezing damage to the battery shell, achieving stable adsorption under high-temperature conditions and improving the adaptability and safety of the device.

[0012] Preferably, the pushing assembly includes a bracket mounted on the base, an electric telescopic rod fixed on the bracket, a bracket fixed to the telescopic end of the electric telescopic rod, and an elastic limiting mechanism mounted on the bracket.

[0013] The effects achieved by the above components are as follows: the electric telescopic rod is fixed by the bracket, and the extension and retraction of the electric telescopic rod drives the bracket and the elastic limiting mechanism to move synchronously. The four ring-shaped push components can achieve synchronous force application to all four sides of the soft-pack battery through the precise extension and retraction control of the electric telescopic rod. The controllability of the electric drive ensures that the force application distance is precisely adjustable, and the ring-shaped structure ensures that the force is evenly distributed around the battery, avoiding the deformation of the aluminum-plastic film caused by the unilateral force application of traditional clamps, achieving uniform force application and reducing the probability of wrinkles.

[0014] Preferably, the elastic limiting mechanism includes a stand fixed on the bracket, a clamping rod slidably inserted on the stand, a protruding ring fixed on the clamping rod, one end of the clamping rod being inserted through and connected to one side of the bracket, and a spring sleeved on the clamping rod between the protruding ring and the bracket.

[0015] The aforementioned components achieve the following effects: the support rod is supported by the upright block, and the support rod, under the action of the spring force, maintains the clamping force on the side of the soft-pack battery through the convex ring. When there are slight differences in battery size or changes in force, the spring can adaptively adjust the clamping force through deformation; multiple equidistantly arranged elastic limiting mechanisms disperse local pressure, making the force on the side of the battery more uniform, achieving flexible and uniform lateral fixation, which not only prevents battery displacement but also avoids wrinkles in the aluminum-plastic film caused by excessive compression, thus increasing the reliability of the packaging.

[0016] This utility model provides an improved soft-pack battery packaging and fixing device, which has the following improvements and advantages compared with the prior art:

[0017] Firstly, this utility model provides an installation base through a base, and the vacuum adsorption component adsorbs and fixes the soft-pack battery from the bottom. At the same time, four ring-shaped pushing components drive the elastic limiting mechanism to approach the soft-pack battery synchronously from all sides. The elastic limiting mechanism forms a flexible clamping force on the side of the battery through elastic force. The adsorption force of the vacuum adsorption component and the ring synchronous clamping force of the elastic limiting mechanism form a three-dimensional fixing system, which realizes the all-round positioning of the soft-pack battery during the heat-sealing process, effectively prevents the sealing edge from being skewed due to pressure slippage of the battery cell, and improves the sealing position accuracy.

[0018] Secondly, this utility model uses a support block to hold the clamping rod in place. Under the action of the spring force, the clamping rod maintains the clamping force on the side of the soft-pack battery through the convex ring. When there are slight differences in battery size or changes in force, the spring can adaptively adjust the clamping force through deformation. Multiple equidistantly arranged elastic limiting mechanisms disperse local pressure, making the force on the side of the battery more uniform, and achieving flexible and uniform lateral fixation. This not only prevents battery displacement but also avoids wrinkles in the aluminum-plastic film caused by excessive compression, thus increasing the reliability of the packaging.

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved soft-pack battery packaging and fixing device. The technical solution of this utility model is as follows:

[0027] In embodiments of this utility model, such as Figures 1-3 As shown, a soft-pack battery packaging and fixing device includes a base 1, on which a vacuum adsorption component 2 is mounted. A high-temperature resistant silicone pad 3 is provided on the top of the adsorption seat 21. The high-temperature resistant silicone pad 3 has a groove 6 communicating with an adsorption hole 23. The high-temperature resistant silicone pad 3 contacts the bottom of the soft-pack battery through the contact between the top of the adsorption seat 21 and the bottom of the soft-pack battery. The groove 6 of the high-temperature resistant silicone pad 3 communicating with the adsorption hole 23 ensures that the negative pressure suction is effectively transferred to the battery. Simultaneously, its high-temperature resistance adapts to the high-temperature environment of heat-sealing. The vacuum adsorption component 2 includes a vacuum adsorption seat 21 mounted on the base 1, and the vacuum adsorption seat 21 contains... A negative pressure chamber 22 is provided for connecting to a negative pressure suction system. The top of the negative pressure chamber 22 has an adsorption hole 23 extending to the outside of the vacuum adsorption seat 21. The negative pressure chamber 22 inside the vacuum adsorption seat 21 is connected to the negative pressure suction system, so that the adsorption hole 23 generates a continuous and stable negative pressure suction force. When the soft-pack battery is placed on the vacuum adsorption seat 21, the negative pressure in the negative pressure chamber 22 acts directly on the bottom of the battery through the adsorption hole 23. The negative pressure adsorption force and the weight of the battery work together to form a tight fit, which realizes the firm fixation of the bottom of the battery and avoids the position displacement of the battery due to the bottom sliding during hot pressing.

[0028] Four ring-shaped pushing components 4 are provided on the outer side of the vacuum adsorption component 2. The pushing components 4 include a bracket 41 mounted on the base 1, an electric telescopic rod 42 fixed on the bracket 41, a bracket 43 fixed to the telescopic end of the electric telescopic rod 42, and an elastic limiting mechanism 5 mounted on the bracket 43. The electric telescopic rod 42 is fixed by the bracket 41. The telescopic extension of the electric telescopic rod 42 drives the bracket 43 and the elastic limiting mechanism 5 to move synchronously. The four ring-shaped pushing components 4 can achieve synchronous force application around the soft pack battery through the precise telescopic extension control of the electric telescopic rod 42.

[0029] The moving end of the pushing component 4 is equipped with multiple equidistantly arranged elastic limiting mechanisms 5. Each elastic limiting mechanism 5 includes a block 51 fixed on the bracket 43, a clamping rod 52 slidably inserted on the block 51, a protruding ring 53 fixed on the clamping rod 52, one end of the clamping rod 52 being inserted through and connected to one side of the bracket 43, and a spring 54 sleeved on the clamping rod 52 between the protruding ring 53 and the bracket 43. The clamping rod 52 is supported by the block 51, and the clamping rod 52 maintains a clamping force on the side of the soft-pack battery through the protruding ring 53 under the elastic force of the spring 54. When there are slight differences in battery size or changes in force, the spring 54 can adaptively adjust the clamping force through deformation. The multiple equidistantly arranged elastic limiting mechanisms 5 disperse local pressure, making the force on the side of the battery more uniform, and achieving flexible and uniform lateral fixation, which not only prevents battery displacement but also avoids wrinkles in the aluminum-plastic film caused by excessive compression.

[0030] The working principle of the soft-pack battery packaging and fixing device provided by this utility model is as follows:

[0031] In the initial state of the device, the base 1 provides installation support for the whole, the vacuum adsorption seat 21 of the vacuum adsorption component 2 is fixed on the base 1, the brackets 41 of the four pushing components 4 are arranged in a ring and installed on the edge of the base 1, and the elastic limiting mechanism 5 is connected to the electric telescopic rod 42 through the bracket 43 and is in the initial open position.

[0032] When the soft-pack battery is placed on top of the vacuum adsorption seat 21, the high-temperature resistant silicone pad 3 contacts the bottom of the battery. The negative pressure suction system generates negative pressure in the adsorption hole 23 through the negative pressure chamber 22. The groove 6 ensures that the negative pressure is effectively transmitted to the bottom of the battery through the high-temperature resistant silicone pad 3, so as to achieve tight adsorption and fixation of the bottom of the battery.

[0033] The electric telescopic rod 42 of the push component 4 is activated. The telescopic rod extends and drives the bracket 43 to move towards the battery. The upright block 51 moves synchronously with the bracket 43, so that the clamping rod 52 gradually approaches the side of the battery.

[0034] After the clamping rod 52 contacts the side of the battery, the spring 54 is squeezed by the convex ring 53 and undergoes elastic deformation, forming a continuous flexible clamping force; the four pushing components 4 act synchronously, and multiple equidistant elastic limiting mechanisms 5 form a ring-shaped uniform constraint on the battery from all sides.

[0035] The bottom adsorption force of the vacuum adsorption component 2 and the annular elastic clamping force of the elastic limiting mechanism 5 form a three-dimensional fixation. During the hot-press sealing process, the negative pressure adsorption prevents the bottom of the battery from sliding, the elastic limiting offsets the impact force of the hot press, and the flexible force application prevents uneven stress on the aluminum-plastic film from causing wrinkles, ultimately achieving stable encapsulation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
