Description

Technical Field

[0001] This utility model belongs to the technical field of electric vehicle assembly equipment, specifically relating to a battery pack and its cell insertion tooling. Background Technology

[0002] In the battery production process, battery pack assembly is a crucial step, requiring the accurate and stable insertion of battery cells into the battery pack housing. Currently, most common cell insertion methods on the market involve manual operation. First, a rear plate 2 is installed at the rear end of housing 1 using a bolt assembly. Then, battery cells 4 are placed on housing 1. Once housing 1 is full of battery cells 4, a front plate 3 is finally installed at the front end of housing 1 using a bolt assembly to secure the battery pack assembly (e.g., ...). Figures 1 to 4 As shown in the figure, this method of manually assembling battery packs has the problems of high labor intensity and slow assembly speed. Utility Model Content

[0003] The problem solved by this utility model is to provide a battery pack and its box-mounting tooling, so as to solve the problems of high labor intensity and slow assembly speed in the existing battery pack assembly.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A shell integrally formed with a rear beam, front beam, cross beam, longitudinal beam, and two side beams is included. The rear beam, front beam, cross beam, longitudinal beam, and two side beams divide the shell into multiple compartments. The multiple compartments are arranged in an array, capable of simultaneously accommodating multiple battery cells, thus improving the assembly efficiency of the battery pack. The device also includes an insertion device for clamping and pressing the battery cells into the compartments. The insertion device includes a base with a translation cylinder, a translation clamping plate, a fixing clamping plate, and a pressure plate at the bottom. The cylinder is connected to the translation clamping plate. The translation cylinder drives the translation clamping plate to move towards the fixed clamping plate to clamp the battery cell. The translation clamping plate and the fixed clamping plate cooperate with each other to stably clamp the battery cell and prevent the battery cell from shifting during clamping. The upper part of the base is provided with a lifting cylinder. The lifting cylinder is connected to the pressure plate. The lifting cylinder drives the pressure plate to rise and fall to press the battery cell into the compartment. The size of the pressure plate is adapted to the overall size of the multiple compartments, so that multiple battery cells can be pressed into the corresponding compartments at the same time, improving the efficiency of entering the box.

[0005] A more specific technical solution to the above technical solution may be as follows: the bottom of the base is provided with a slide rail and a support. There are two slide rails, which are arranged parallel to each other on both sides of the bottom of the base. The top two sides of the translation clamp are provided with sliding grooves that are adapted to the slide rails. The translation clamp is slidably connected to the slide rails through the sliding grooves to ensure the stability of the translation clamp during the translation process and to avoid deviation. The cylinder body of the translation cylinder is connected to the translation clamp, and the piston rod of the translation cylinder is connected to the support. The extension and retraction direction of the piston rod is consistent with the length direction of the slide rail to ensure that the translation cylinder can stably drive the translation clamp to translate along the slide rail.

[0006] Furthermore, the pressure plate is equipped with four guide rods, which are fixed at the four corners of the top of the pressure plate. The base has four guide holes that are adapted to the guide rods, located at the four corners of the base. The guide rods are inserted into the guide holes and slide in cooperation with the guide holes. The guide rods play a guiding role during the lifting and lowering of the pressure plate, preventing the pressure plate from tilting and ensuring that the pressure plate can accurately press the battery cells into the compartment, thereby improving the accuracy of the battery cells being placed into the compartment.

[0007] Furthermore, anti-slip buffer pads are provided on the opposing sidewalls of both the fixed clamping plate and the translation clamping plate.

[0008] Furthermore, the anti-slip buffer pad is a rubber pad, which is fixed to the fixed clamp and the translation clamp by adhesive. The rubber pad has good elasticity and cushioning performance. When clamping the battery cell, it can prevent the fixed clamp and the translation clamp from directly contacting the battery cell, preventing the surface of the battery cell from being scratched. At the same time, it can also increase the friction between the fixed clamp and the translation clamp and the battery cell, and improve the stability of clamping.

[0009] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: By using an integrated molding structure, the rear beam, front beam, cross beam, longitudinal beam, and side beams divide the shell into multiple array-distributed compartments, resulting in a stable structure. It eliminates the need for manual installation of the rear and front end panels and can simultaneously accommodate multiple sets of battery cells, providing a foundation for subsequent batch assembly. Furthermore, the batch assembly device presses multiple sets of battery cells into the compartments, improving the battery pack assembly efficiency. This significantly improves the efficiency of battery cell assembly, reduces labor costs, and is suitable for large-scale mass production. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and examples: like Figures 5 to 8The battery pack and its mounting fixture shown include a housing 1 integrally formed with a rear beam 11, a front beam 12, a crossbeam 13, a longitudinal beam 14, and two side beams 15. The rear beam 11, front beam 12, crossbeam 13, longitudinal beam 14, and two side beams 15 divide the housing 1 into multiple compartments. These compartments are arranged in an array, capable of simultaneously accommodating multiple battery cells 4, thus improving the assembly efficiency of the battery pack. It also includes a mounting device 5 for clamping the battery cells 4 and pressing them into the compartments. The mounting device 5 includes a base 51 with a translation cylinder 52, a translation clamping plate 53, a fixing clamping plate 54, and a pressure plate 57 at the bottom. 2. Connected to the translation clamping plate 53, the translation cylinder 52 drives the translation clamping plate 53 to move towards the fixed clamping plate 54 to clamp the battery cell 4. The translation clamping plate 53 and the fixed clamping plate 54 cooperate with each other to stably clamp the battery cell 4 and prevent the battery cell 4 from shifting during clamping. The upper part of the base 51 is provided with a lifting cylinder 56, which is connected to the pressure plate 57. The lifting cylinder 56 drives the pressure plate 57 to rise and fall to press the battery cell 4 into the compartment. The size of the pressure plate 57 is adapted to the overall size of the multiple compartments, so that multiple battery cells 4 can be pressed into the corresponding compartments at the same time, improving the efficiency of entering the box. The bottom of the base 51 is provided with a slide rail and a support 55. There are two slide rails, which are arranged parallel to each other on both sides of the bottom of the base 51. The top two sides of the translation clamp 53 are provided with slide grooves that are adapted to the slide rails. The translation clamp 53 is slidably connected to the slide rails through the slide grooves to ensure the stability of the translation clamp 53 during the translation process and to avoid deviation. The cylinder body of the translation cylinder 52 is connected to the translation clamp 53, and the piston rod of the translation cylinder 52 is connected to the support 55. The extension and retraction direction of the piston rod is consistent with the length direction of the slide rail, ensuring that the translation cylinder 52 can stably drive the translation clamp 53 to move along the slide rail. The pressure plate 57 is equipped with four guide rods, which are fixed at the four corners of the top of the pressure plate 57. The base 51 has four guide holes 58 that are adapted to the guide rods, located at the four corners of the base 51. The guide rods are inserted into the guide holes 58 and slide in cooperation with the guide holes 58. The guide rods play a guiding role during the lifting and lowering of the pressure plate 57, preventing the pressure plate 57 from tilting and ensuring that the pressure plate 57 can accurately press the battery cell 4 into the compartment, thus improving the accuracy of the insertion. Rubber pads 59 are provided on the opposing side walls of the fixed clamping plate 54 and the sliding clamping plate 53. The rubber pads 59 are fixed to the fixed clamping plate 54 and the sliding clamping plate 53 by adhesive. The rubber pads 59 have good elasticity and cushioning performance. When clamping the battery cell 4, they can avoid direct contact between the fixed clamping plate 54 and the sliding clamping plate 53 and the battery cell 4, preventing the surface of the battery cell 4 from being scratched. At the same time, they can also increase the friction between the fixed clamping plate 54 and the sliding clamping plate 53 and the battery cell 4, thus improving the stability of the clamping.
