Description

Technical Field

[0001] This utility model belongs to the technical field of battery module assembly equipment, and in particular relates to a high-efficiency assembly equipment for MEB battery module production. Background Technology

[0002] The MEB battery module is the power battery module used in the MEB (Modular Electric Drive Kit) modular platform for pure electric vehicles developed by a certain car brand. Each module consists of 24 cells, with each cell having an energy density of 240Wh / kg, and the entire battery pack having a maximum energy density of 175Wh / kg. The standardized design of the MEB battery module significantly reduces the size of lithium batteries, adapting to the development needs of electric vehicles. At the same time, the platform design supports global unified procurement, which helps reduce costs and improve battery quality and development efficiency. The production process of the battery module includes key processes such as cell assembly, connection, and testing. With the development of automated equipment, assembly equipment used in battery module production is gradually replacing manual operation. Compared with manual assembly, assembly equipment is not only more efficient, but also ensures the accuracy and consistency of the products. A search revealed a Chinese patent (publication number: CN218548506U) that discloses a battery module assembly equipment for assembling a battery cell stack with a rectangular frame. The battery module assembly equipment includes a tooling platform, a clamping device, a rectangular frame guide rail, and a rectangular frame drive assembly. The clamping device is disposed on the tooling platform and includes multiple clamp groups spaced apart along a first direction and clamp drive assemblies corresponding to each clamp group. The clamp drive assembly drives the corresponding clamp groups to clamp the battery cell stack. The rectangular frame guide rail is disposed on the tooling platform and extends along the first direction. The rectangular frame is configured to slide on the rectangular frame guide rail. The rectangular frame drive assembly drives the rectangular frame to move along the first direction so that the rectangular frame can be fitted onto the battery cell stack. However, during use, the clamping device, rectangular frame guide rail, and rectangular frame drive assembly on the tooling platform can only clamp and assemble one workpiece at a time, resulting in low efficiency and failing to meet the needs of mass production. Therefore, a high-efficiency assembly equipment for MEB battery module production is needed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a high-efficiency assembly equipment for MEB battery module production, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency assembly equipment for MEB battery module production includes: The equipment body includes a worktable and a sliding plate. The two ends of the sliding plate are slidably disposed on the worktable, and the lower end surface of the worktable is spaced a predetermined distance from the upper end surface of the sliding plate. The worktable is provided with a sliding groove, the axis of which is perpendicular to the movement direction of the sliding plate. The sliding plate is provided with multiple moving grooves. With the center line of the sliding plate as a reference, the multiple moving grooves are arranged in two groups. The two groups of moving grooves are symmetrically distributed with the center line of the sliding plate as the center. In the direction away from the center line of the sliding plate, the angle between the axial direction of each moving groove in each group and the center line of the sliding plate increases arithmetically. A clamping mechanism includes multiple clamping plates, which are vertically arranged on the upper surface of the worktable. Each clamping plate has a sliding post on its lower surface. Each sliding post is slidably arranged in each sliding groove and is movably arranged in the sliding groove. An ejection mechanism is disposed on the worktable.

[0005] In a further technical solution, the clamping mechanism further includes a rotating rod and a motor. A fixing block is provided on the lower end face of the sliding plate, and a threaded hole is provided on the sliding plate on the fixing block. The rotating rod is threadedly connected to the threaded hole. The rotating rod is rotatably mounted on the worktable. The motor is mounted on the worktable, and the output shaft of the motor is connected to the rotating rod.

[0006] In a further technical solution, the ejection mechanism includes a sliding rod and multiple ejector rods. The sliding rod is slidably and vertically mounted on the upper surface of the worktable, and the multiple ejector rods are spaced apart and mounted on the side wall of the sliding rod. The two adjacent clamping plates are symmetrically distributed with the middle ejector rod as the center.

[0007] In a further technical solution, the ejection mechanism also includes a pair of cylinders, which are mounted on the worktable, and the output shaft of the cylinders is connected to the end of the sliding rod.

[0008] In a further technical solution, the main body of the equipment also includes a fixed rod, and the clamping mechanism also includes multiple sliding blocks. Each sliding block is connected to the lower end of each clamping plate, and each sliding block is provided with a sliding hole. The two ends of the fixed rod are fixedly installed on the lower end face of the workbench, and the fixed rod is inserted into the sliding hole. The axial direction of the fixed rod is parallel to the axial direction of the sliding groove, and the moving column is formed on the lower end face of the sliding block.

[0009] In a further technical solution, a limiting block is provided at one end of the clamping plate near the sliding rod, and the limiting blocks on two adjacent clamping plates are spaced apart by a predetermined distance.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a clamping mechanism comprising multiple clamping plates vertically positioned on the upper surface of a worktable. Each clamping plate has a movable column on its lower surface, and each movable column is slidably positioned in a moving groove and movable within a sliding groove. Multiple battery module housings to be assembled are manually or automatically transferred one by one to the upper surface of the worktable and placed between adjacent clamping plates. A sliding plate moves perpendicular to the sliding groove, causing the movable columns in the moving groove to move closer to each other until the opposite sidewalls of the two adjacent clamping plates abut against the opposite sidewalls of the housing in the middle. In this way, each housing is clamped to the upper surface of the worktable by two adjacent clamping plates. A robotic arm can then simultaneously assemble multiple housings, improving efficiency and making it suitable for mass production. This invention features an ejection mechanism comprising a sliding rod and multiple ejector rods. The sliding rod is slidably and vertically mounted on the upper surface of the worktable, while the ejector rods are spaced apart on the sidewalls of the sliding rod, with adjacent clamping plates symmetrically distributed around the central ejector rod. A cylinder is mounted on the worktable, and its output shaft is connected to the end of the sliding rod. After assembly, the motor first drives the rotating rod to rotate in the opposite direction, causing the adjacent clamping plates to move the same distance away from each other. Subsequently, the activated cylinder drives the sliding rod to slide closer to the clamping plates, causing the ejector rods on the sliding rod to slide between the adjacent clamping plates until the ejector rods remove the assembled housing from between the adjacent clamping plates. This eliminates the need for manual removal by workers, demonstrating the high degree of automation of the equipment.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] like Figures 1 to 4 As shown, this utility model embodiment provides a high-efficiency assembly equipment for MEB battery module production, comprising: The main body of the equipment 1 includes a workbench 11 and a sliding plate 12. The two ends of the sliding plate 12 are slidably disposed on the workbench 11, and the lower end surface of the workbench 11 is separated from the upper end surface of the sliding plate 12 by a predetermined distance. The workbench 11 is provided with a sliding groove 111, the axis of which is perpendicular to the movement direction of the sliding plate 12. The sliding plate 12 is provided with a plurality of moving grooves 121. Taking the center line of the sliding plate 12 as a reference, the plurality of moving grooves 121 are configured into two groups. The two groups of moving grooves 121 are symmetrically distributed around the center line of the sliding plate 12. In the direction away from the center line of the sliding plate 12, the angle between the axis of each moving groove 121 in each group and the center line of the sliding plate 12 increases arithmetically. The clamping mechanism 2 includes multiple clamping plates 21, which are vertically arranged on the upper surface of the worktable 11. Each clamping plate 21 has a moving post 211 on its lower surface. Each moving post 211 is slidably arranged in each moving groove 121 and is movably arranged in the sliding groove 111. Ejection mechanism 3 is provided on worktable 11; In this embodiment, during use, multiple battery module housings to be assembled are manually or automatically transferred one by one to the upper surface of the workbench 11 and placed between two adjacent clamping plates 21. The sliding plate 12 moves along a direction perpendicular to the sliding groove 111, at which time multiple movable columns 211 placed in the moving groove 121 move towards each other until the opposite sidewalls of the two adjacent clamping plates 21 abut against the opposite sidewalls of the middle housing. In this way, each housing is clamped on the upper surface of the workbench 11 by two adjacent clamping plates 21. Then, the robot can perform assembly operations on multiple housings simultaneously, improving efficiency and making it suitable for mass production. Specifically, the clamping mechanism 2 also includes a rotating rod 22 and a motor 23. A fixing block 122 is provided on the lower end face of the sliding plate 12, and a threaded hole 123 is provided on the fixing block 122 of the sliding plate 12. The rotating rod 22 is threadedly connected to the threaded hole 123. The rotating rod 22 is rotatably mounted on the worktable 11. The motor 23 is mounted on the worktable 11, and the output shaft of the motor 23 is connected to the rotating rod 22. In this embodiment, after starting, the motor 23 drives the rotating rod 22 to rotate, thereby causing the sliding plate 12 to move along a direction perpendicular to the slide groove 111; Specifically, the ejection mechanism 3 includes a sliding rod 31 and multiple ejector rods 32. The sliding rod 31 is slidably and vertically installed on the upper end face of the worktable 11. The multiple ejector rods 32 are spaced apart on the side wall of the sliding rod 31, and two adjacent clamping plates 21 are symmetrically distributed with the middle ejector rod 32 as the center. Specifically, the ejection mechanism 3 also includes a pair of cylinders 33, which are mounted on the worktable 11 and whose output shafts are connected to the end of the sliding rod 31. In this embodiment, after assembly, the motor 23 first drives the rotating rod 22 to rotate in the opposite direction so that the two adjacent clamping plates 21 move the same distance away from each other; then, the activated cylinder 33 drives the sliding rod 31 to slide towards the clamping plate 21 so that the push rod 32 on the sliding rod 31 slides between the two adjacent clamping plates 21 until the push rod 32 moves the assembled shell out from between the two adjacent clamping plates 21 without the need for manual removal by workers, demonstrating the degree of automation of the equipment; Specifically, the main body 1 of the equipment also includes a fixed rod 13, and the clamping mechanism 2 also includes a plurality of sliding blocks 24. Each sliding block 24 is connected to the lower end of each clamping plate 21. Each sliding block 24 is provided with a sliding hole 241. The two ends of the fixed rod 13 are fixedly installed on the lower end face of the workbench 11. The fixed rod 13 is inserted into the sliding hole 241. The axial direction of the fixed rod 13 is parallel to the axial direction of the slide groove 111. The moving column 211 is formed on the lower end face of the sliding block 24. In this embodiment, during the movement of the sliding plate 12, the sliding block 24 moves axially along the fixed rod 13. By setting the sliding block 24 and the fixed rod 13, the movement of the clamping plate 21 is made more stable. Specifically, a limiting block 212 is provided at one end of the clamping plate 21 near the sliding rod 31, and the limiting blocks 212 on two adjacent clamping plates 21 are spaced apart by a predetermined distance.

[0017] The working principle of this utility model is as follows: In use, multiple battery module housings to be assembled are manually or automatically transferred one by one to the upper surface of the workbench 11 and placed between two adjacent clamping plates 21, ensuring that the sidewalls of the housings abut against the limiting blocks 212. Subsequently, the motor 23, after starting, drives the rotating rod 22 to rotate, which in turn drives the sliding plate 12 to move along a direction perpendicular to the slide groove 111. At this time, multiple moving columns 211 placed in the moving groove 121 move towards each other until the opposite sidewalls of two adjacent clamping plates 21 abut against the opposite sidewalls of the middle shell. In this way, each shell is clamped on the upper surface of the worktable 11 by two adjacent clamping plates 21. Then, the robot can perform assembly operations on multiple shells simultaneously, improving efficiency and making it suitable for mass production. In addition, during the movement of the sliding plate 12, the sliding block 24 moves axially along the fixed rod 13. By setting the sliding block 24 and the fixed rod 13, the movement of the clamping plate 21 is made more stable. After assembly, the motor 23 first drives the rotating rod 22 to rotate in the opposite direction, so that the two adjacent clamping plates 21 move the same distance away from each other. Then, the activated cylinder 33 drives the sliding rod 31 to slide towards the clamping plate 21, so that the push rod 32 on the sliding rod 31 slides between the two adjacent clamping plates 21 until the push rod 32 removes the assembled shell from between the two adjacent clamping plates 21. This eliminates the need for manual removal by workers, demonstrating the automation level of the equipment.

[0018] 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.
