As the power source for new energy electric vehicles, the safety of the power battery is of paramount importance. The power battery is composed of multiple integrated lithium batteries.

[0003] Currently, battery module assembly on the market is still mainly done manually or semi-automatically, which has the problems of high labor costs and low efficiency. Operators need to manually complete cell stacking, end plate positioning, and bolt tightening, which is not only labor-intensive but also difficult to ensure consistency. At the same time, the accuracy of manual leveling is poor, which can easily lead to module alignment deviations, affecting subsequent welding or busbar installation and reducing the overall yield. In addition, the equipment in semi-automatic production lines is scattered and independent. Processes such as cell loading, module pressing, and bolt tightening need to be laid out in sections, which not only occupies a large area but also has low efficiency in connecting each link, which restricts the increase in production capacity and makes it difficult to meet the needs of large-scale production.

[0004] To address the aforementioned problems, this utility model proposes a battery cell assembly machine. Utility Model Content

Leveling plates are movably arranged on the opposite ends of the two leveling boxes, and the leveling plates abut against the side walls of the battery cell module. A lifting assembly is provided at the top of the base corresponding to the position of the battery cell module.

[0007] The present invention is further configured such that a first electric cylinder is fixedly installed inside the extrusion box, the output end of the first electric cylinder extends to the outside of the extrusion box, a push plate is fixedly installed on the output end of the first electric cylinder, a plurality of pressure sensors are fixedly installed on the push plate, and an extrusion positioning plate is fixedly installed on the end of the pressure sensors away from the push plate.

[0008] The present invention is further configured such that a support plate is fixedly installed inside the leveling box, and multiple cylinders are fixedly installed on the support plate, with the output end of the cylinders fixedly connected to the leveling plate.

[0009] The present invention is further configured such that a plurality of limiting slide rods are slidably installed on the support plate, and one end of the limiting slide rod is fixedly connected to the finding plate.

[0010] The present invention is further configured such that the lifting assembly includes a lifting cylinder and a top plate; the lifting cylinder is embedded in the top of the base, and the top plate is fixedly installed on the output end of the lifting cylinder, and the top plate abuts against the bottom surface of the battery cell module.

[0011] The present invention is further configured such that U-shaped clamps are fixedly installed on both sides of the battery cell module for hoisting.

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

[0024] Please see Figure 1-4 This utility model provides a technical solution: a battery cell assembly machine, including a base 1 and a battery cell module 5.

[0025] On both the left and right sides of the upper end face of the base 1, extrusion boxes 2 are fixedly installed. Push plates 3 are slidably mounted on opposite ends of the two extrusion boxes 2, and extrusion positioning plates 4 are fixedly mounted on opposite surfaces of the two push plates 3. Specifically, a first electric cylinder 8 is fixedly installed inside each extrusion box 2. The output end of the first electric cylinder 8 extends to the outside of the extrusion box 2. The push plate 3 is fixedly mounted on the output end of the first electric cylinder 8. Multiple pressure sensors 9 are fixedly mounted on the push plate 3. The extrusion positioning plate 4 is fixedly mounted on the end of the pressure sensors 9 opposite to the push plate 3.

[0026] By adopting the above technical solutions, the layout of the base 1 and the extrusion box 2 provides stable support for the overall equipment, and the two symmetrically arranged extrusion boxes 2 ensure balanced force; the sliding arrangement of the push plate 3, in conjunction with the drive of the first electric cylinder 8, enables the extrusion positioning plate 4 to achieve positioning adjustment; the integrated design of the pressure sensor 9 enables real-time monitoring and feedback of the clamping force, effectively preventing overpressure damage to the battery cell.

[0027] The battery cell module 5 is positioned between two extrusion positioning plates 4.

[0028] Leveling boxes 6 are fixedly installed on both the front and rear sides of the upper end of the base 1. A leveling plate 7 is movably mounted on the opposite ends of the two leveling boxes 6, and the leveling plate 7 abuts against the side wall of the battery cell module 5. Specifically, a support plate 10 is fixedly installed inside the leveling box 6, and multiple cylinders 11 are fixedly installed on the support plate 10. The output end of the cylinders 11 is fixedly connected to the leveling plate 7.

[0029] By adopting the above technical solutions, the symmetrical design of the two extrusion positioning plates 4 ensures uniform distribution of clamping force. The symmetrical arrangement of the leveling box 6 provides a benchmark for horizontal correction, and the rigid installation of the support plate 10 ensures stable force application by the cylinder 11. The guiding effect of the limiting slide rod 12 makes the movement of the leveling plate 7 more stable, ensuring the accuracy of horizontal correction.

[0030] In this embodiment of the utility model: a plurality of limiting slide rods 12 are slidably installed on the support plate 10, and one end of the limiting slide rod 12 is fixedly connected to the finding plate 7.

[0031] A lifting assembly is provided at the top of the base 1 corresponding to the position of the battery cell module 5. The lifting assembly includes a lifting cylinder 13 and a top plate 14; the lifting cylinder 13 is embedded in the top of the base 1, and the top plate 14 is fixedly installed on the output end of the lifting cylinder 13, and the top plate 14 abuts against the bottom surface of the battery cell module 5.

[0032] In this embodiment of the invention, U-shaped clamps 15 are fixedly installed on both sides of the battery cell module 5. The U-shaped clamps 15 facilitate the handling and positioning of the module.

[0033] In this embodiment of the invention: a bracket 16 is fixedly installed on one side of the upper end face of the base 1, and a CCD inspection camera 17 is fixedly installed on the bracket 16. The independent installation of the bracket 16 provides a stable viewing angle for the CCD inspection camera 17, ensuring inspection accuracy.

[0034] Working principle:

[0035] During use, the operator places the battery cell module 5 stably on the worktable of the top plate 14. At this time, the output shaft of the lifting cylinder 13 is fully extended, which is the initial working position. After the lifting cylinder 13 is started, its output shaft begins to retract at a constant speed, driving the top plate 14 to descend smoothly in the vertical direction, accurately transporting the battery cell module 5 to the predetermined working area between the two leveling boxes 6, completing the initial positioning. This pre-positioning process can significantly shorten the subsequent adjustment time and improve the overall operating efficiency.

[0036] After positioning is completed, the system automatically activates the cylinders 11 on both sides, driving the leveling plates 7 to move synchronously towards each other along the horizontal guide rail. This ensures that both leveling plates 7 simultaneously contact both sides of the battery cell module 5 and apply a balanced thrust, ensuring the module reaches a precise horizontal state. After horizontal correction, the first electric cylinder 8 starts working, pushing the push plate 3 to smoothly feed towards the battery cell module 5 along the linear guide rail. This, in turn, drives the extrusion positioning plate 4 to precisely position and clamp the battery cell module 5. The system monitors the extrusion force in real time through a high-precision pressure sensor 9 and automatically adjusts the output force of the electric cylinder 8 according to a preset program. This ensures that the optimal clamping force can be applied to battery cell modules 5 of different models and specifications, guaranteeing both positioning stability and preventing overpressure damage to the battery cells.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
