Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a clustering mechanism for industrial energy storage lithium batteries. Background Technology

[0002] Lithium-ion batteries are used to store electrical energy, primarily for releasing it when needed. They feature high energy density, long lifespan, and low maintenance. Lithium-ion batteries store and release electrical energy through the movement of lithium ions between the positive and negative electrodes. This reversible electrochemical reaction process is highly efficient and capable of multiple charge-discharge cycles, providing a stable and reliable energy source for various applications.

[0003] Chinese patent CN202420393336.8 discloses a battery pack clustering fixture, including a support base and a transfer base. The support base has a first inclined surface with a plurality of first roller groups arranged on it. The transfer base has a second inclined surface matching the first inclined surface, and a plurality of second roller groups are arranged on the surface of the transfer base opposite to the second inclined surface. The second inclined surface can abut against the first roller groups, allowing the transfer base to slide relative to the support base along the first inclined surface. When using this battery pack clustering fixture to transport battery packs, the bottom of the battery pack rolls into contact with the second roller groups, which can reduce wear on the bottom of the battery pack and damage to the integrity of the cluster frame, while also reducing production costs.

[0004] However, this technical solution lacks a driving structure. The energy storage batteries need to be installed into the energy storage station according to requirements, but the batteries themselves are large and extremely heavy. Existing clustering fixtures require external force or heat to drive them, which not only easily damages the batteries but also results in excessive friction due to their weight. This makes manual operation extremely difficult, making it hard to ensure proper installation and compromising operational safety. The newly designed automatic clustering fixture uses modules to precisely control the battery advancement distance, and pressure sensors can set the maximum thrust to ensure no damage to the batteries or the energy storage station. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a clustering mechanism for industrial energy storage lithium batteries. This mechanism uses a servo motor module in conjunction with a pressure sensor and positioning components to achieve the clustering function, thus solving the problem of difficult clustering.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0011] The top of the transport base plate is provided with two sets of U-shaped connecting sleeves, which are symmetrically distributed on the top of the transport base plate. The top of each set of U-shaped connecting sleeves is threaded with a connecting bolt.

Furthermore, the positioning components, transport base plate and guide rollers make the mechanism applicable to multiple battery models, with high degree of freedom and strong applicability. The pressure sensor controls the thrust to ensure that the pressure will not be too high and damage the battery after it is pushed into place.

[0016] (2) This utility model uses two sets of driving cylinders to push two sets of positioning sliders to move and provide them with clamping pressure.

[0030] Example:

[0031] like Figures 1-7 As shown, this embodiment provides a clustering mechanism for industrial energy storage lithium batteries, including a structural base 1 and two sets of linear guide rails 2 on the top of the structural base 1. The two sets of linear guide rails 2 are symmetrically distributed on the top of the structural base 1. A transport base plate 3 is provided on the top of the structural base 1. A servo motor 4 is provided at one end of each set of linear guide rails 2. A reducer 5 is installed at one end of the output shaft of the servo motor 4. A drive screw 7 is provided inside each set of linear guide rails 2. A nut slider 8 is fixedly connected to the bottom of the transport base plate 3. The nut slider 8 has a... A lead screw nut 9 is installed; two sets of pressure sensors 12 are installed on one side of the linear guide rail 2, and the two sets of pressure sensors 12 are symmetrically distributed on one side of the linear guide rail 2; two sets of nitrogen spring push rods 13 are installed on one side of the end plate of the structural base 1, and the two sets of nitrogen spring push rods 13 are symmetrically distributed on one side of the end plate of the structural base 1; a positioning seat 16 is fixedly connected above the top bracket of the transport base plate 3, and two sets of positioning sliders 17 are movably connected to the top of the positioning seat 16, and the two sets of positioning sliders 17 are symmetrically distributed on the top of the positioning seat 16.

[0032] The structure includes a base 1 that supports the upper components and guides the battery during transport via two sets of linear guides 2. The transport base 3 serves as the main support structure for the battery. A lead screw 9 in the bottom nut slider 8 connects to a drive screw 7, which, when the servo motor 4 is powered on, drives the drive screw 7, thus moving the transport base 3 along the linear guides 2 to transport the battery. The reducer 5 reduces motor speed while increasing output torque. Combined with the servo motor 4 and two pressure sensors 12, it effectively improves transmission accuracy and the precision of displacement control, further reducing frictional resistance during battery insertion. Two nitrogen spring push rods 13 utilize the compression and expansion of nitrogen to create elasticity. The high-pressure gas generates significant pressure upon compression, achieving the elastic effect. The magnitude of the elasticity can be precisely controlled by adjusting the pressure intensity. The positioning seat 16 is a battery positioning component. Two positioning sliders 17 engage with grooves at the bottom of the battery casing to clamp and position the battery, ensuring stability during insertion and preventing detachment.

[0033] Two sets of lead screw bearings 6 are provided on the top of the structural base 1, and the two sets of lead screw bearings 6 are symmetrically distributed on the top of the structural base 1.

[0034] Among them, the use of two sets of lead screw bearings 6 provides support for the drive lead screw 7, ensuring its rotational efficiency.

[0035] Two sets of guide rail sliders 10 are also fixedly connected to the bottom of the transport base plate 3. The two sets of guide rail sliders 10 are symmetrically distributed at the bottom of the transport base plate 3.

[0036] Among them, two sets of guide rail sliders 10 can be movably connected to two sets of linear guide rails 2, thereby limiting and guiding the transport base plate 3 and ensuring its stability during movement.

[0037] Multiple sets of guide rollers 11 are movably connected in the grooves on both sides of the top of the structural base 1, and the multiple sets of guide rollers 11 are linearly distributed in the grooves on both sides of the top of the structural base 1.

[0038] Among them, multiple sets of guide rollers 11 can roll in the grooves on both sides of the top of the structural base 1, thereby effectively reducing the frictional resistance of the battery when moving, reducing the wear on the electromagnetic field when entering the cluster and effectively improving the clustering efficiency.

[0039] The top of the transport base plate 3 is provided with two sets of U-shaped connecting sleeves 14. The two sets of U-shaped connecting sleeves 14 are symmetrically distributed on the top of the transport base plate 3, and the top of the two sets of U-shaped connecting sleeves 14 are threaded with connecting bolts 15.

[0040] Among them, two sets of U-shaped connecting sleeves 14 can be fitted onto the rod head of the nitrogen spring push rod 13 and connected and locked by connecting bolts 15, thereby realizing the connection between the output end of the nitrogen spring push rod 13 and the transport base plate 3.

[0041] Assembly blocks 18 are installed on the top of both sets of positioning sliders 17. Rubber pads 19 are installed on one side of the assembly blocks 18. Two sets of assembly bolts 20 are threadedly connected to the top of the assembly blocks 18. The two sets of assembly bolts 20 are symmetrically distributed on the top of the assembly blocks 18.

[0042] The mounting clamp 18 has a groove at its bottom end that can be inserted into the positioning slider 17 and locked by two sets of mounting bolts 20. This allows the user to select the corresponding mounting clamp 18 according to the groove at the bottom end of the battery casing of different specifications, thereby greatly improving the applicability of the device. The use of rubber pad 19 improves the clamping effect of the mounting clamp 18 and further reduces wear on the battery.

[0043] Two sets of drive cylinders 21 are installed at both ends of the positioning seat 16. The two sets of drive cylinders 21 are symmetrically distributed at both ends of the positioning seat 16. An air receiving end 22 is provided on one side of the drive cylinder 21. Two sets of guide grooves 23 are provided on the inner wall of the positioning seat 16. The two sets of guide grooves 23 are symmetrically distributed on the inner wall of the positioning seat 16.

[0044] Among them, two sets of drive cylinders 21 can be connected to the air inlet and outlet pipes through the air inlet end 22, so that they can drive the positioning slider 17 and provide clamping pressure when the power is turned on; the two sets of guide slide grooves 23 can be movably connected to the protrusions on both sides of the positioning slider 17, so as to realize the limiting and guiding of the positioning slider 17 and ensure its stability when moving.

[0045] Work steps:

[0046] The user places the battery to be loaded onto the structural base 1 using a forklift or lifting device. The top transport base plate 3 and the guide rollers 11 on both sides support the battery. Then the user connects the air pipe to the drive cylinder 21 and powers it on. When it is powered on, it will push the assembly clamping blocks 18 on the two sets of positioning sliders 17 to move inward through the output rod and clamp the battery with the bottom groove of the battery casing to position the battery.

[0047] Then, the user powers on the servo motor 4. When the servo motor 4 is powered on and started, it will drive the drive screw 7 to rotate on the screw bearing 6 through the coupling on the output shaft. The screw nut 9 on the bottom nut slider 8 of the transport base plate 3 is connected to the drive screw 7, so that the transport base plate 3 can slide along the two sets of linear guide rails 2. At the same time, the user fills the nitrogen spring push rod 13 with inert gas or oil-gas mixture, so that the pressure in the cavity is several times or tens of times higher than atmospheric pressure. Since the cross-sectional area of ​​the piston rod in the nitrogen spring push rod 13 is smaller than the cross-sectional area of ​​the piston, a pressure difference is generated, which pushes the piston rod in the nitrogen spring push rod 13 to move, thereby providing thrust to the transport base plate 3, thus realizing the transport of the battery.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
