[0002] Currently, the industry's blade battery cells undergo rolling, dust removal, and 3D profilometry testing after peripheral welding using a station-based approach. This involves a mechanical gripper sequentially gripping the battery cell at the rolling station, followed by a 3D profilometry test station for positioning and 3D scanning. At the rolling station, the product remains stationary while rollers roll the two long sides. Next, at the dust removal station, the product remains stationary while dust removal brushes clean the rolled area. Finally, a robotic arm picks up the battery cell and transfers it to the 3D profilometry test station. Once stationary, the module, carrying the 3D profilometry component, scans the long sides.

[0003] Conventional solutions cannot meet the needs of high-speed production lines. To meet the needs of high-speed production lines, several corresponding process stations need to be added, which will greatly increase the footprint of the equipment and the investment cost.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1 Reference Figure 3 , Figure 4 A battery cell dust removal and testing device includes a roller pressing dust removal and testing mechanism 2. Specifically, the roller pressing dust removal and testing mechanism 2 includes a base plate 21, a front and rear adjustment module 22, a left and right adjustment module 23, a contour measuring instrument component 24, a roller pressing component 25, a rotary dust removal component 26, a moving platform 27, a drive cylinder 28, a connecting bracket 29, a connecting seat 210, a slider 211, a slide rail 212, and a cam groove 213. The base plate 21, the front and rear adjustment module 22, and the left and right adjustment module 23 are located below the moving platform 27, and the remaining structures are located above the moving platform 27.

[0023] Reference Figure 3 , Figure 4The base plate 21 is located at the bottom and has several mounting holes for subsequent fixation to both sides of the magnetic levitation production line. A front-to-back adjustment module 22 is mounted on the top of the base plate 21. The output end of the front-to-back adjustment module 22 is detachably connected to a left-to-right adjustment module 23 via bolts or pins. The output end of the left-to-right adjustment module 23 is detachably connected to the moving platform 27 via bolts or pins. It should be noted that the front-to-back adjustment module 22 and the left-to-right adjustment module 23 can be made of linear motors or ball screws, which are commonly used in the field. This application will not elaborate on their principles. Therefore, the front-to-back adjustment module 22 can drive the moving platform 27 and its mechanisms to move in the front-to-back direction, and the left-to-right adjustment module 23 can drive the moving platform 27 and its mechanisms to move in the left-to-right direction.

[0024] For ease of understanding and description, Figure 3 The center arrow indicates that the marked front, back, left, and right directions are the reference, and the other directions are inferred from this reference. It should be understood that this orientation setting is only for the convenience of description and understanding, and should not be construed as a limitation of this application.

[0025] Reference Figure 3 , Figure 4 The top of the mobile platform 27 is detachably mounted with a vertical plate and a mounting plate 244 by bolts or pins, wherein the mounting plate 244 is located on one side of the vertical plate.

[0026] Reference Figure 8 A contour measuring instrument detection assembly 24 is installed on the mounting plate 244. The contour measuring instrument detection assembly 24 includes an adjusting screw assembly 241, a 3D contour measuring instrument 242, and an angle adjusting plate 243. Two sets of adjusting screw assemblies 241 are provided, and the two sets of adjusting screw assemblies 241 are symmetrically installed on the mounting plate 244 and can be detached from the mounting plate 244 by bolts or pins.

[0027] Reference Figure 8 The adjusting screw assembly 241 includes a slide rod and a slider. A screw is set at the top of the slide rod, and the slider is connected to the bottom of the screw rod. By rotating the screw rod, the slider can be driven to slide along the slide rod. The slide rod is set in the vertical direction. An angle adjusting plate 243 is connected to the slider, and the angle adjusting plate 243 is connected to the 3D contour detector 242. Specifically, the angle adjustment plate 243 has an arc-shaped groove, and the 3D contour detector 242 is connected to the arc-shaped groove through a connecting block. By adjusting the position of the connecting block in the arc-shaped groove, the angle of the 3D contour detector 242 can be adjusted. The screw can drive the slider, the angle adjustment plate 243, and the 3D contour detector 242 to make vertical adjustments. Therefore, the above structure can adjust the distance between the two sets of 3D contour detectors 242, and can also adjust the angle of each 3D contour detector 242 individually.

[0028] Reference Figure 4 , Figure 5 The upright plate is equipped with a roller pressing assembly 25, a rotary dust removal assembly 26, a drive cylinder 28, a connecting bracket 29, a connecting seat 210, a slider 211, and a slide rail 212. There are two sets of roller pressing assemblies 25 and two sets of rotary dust removal assemblies 26. The two sets of roller pressing assemblies 25 and the two sets of rotary dust removal assemblies 26 are arranged symmetrically from top to bottom. The upper roller pressing assembly 25 and the rotary dust removal assembly 26 are mounted on the upper slider 211, and the lower roller pressing assembly 25 and the rotary dust removal assembly 26 are mounted on the lower slider 211. The two sets of sliders 211 can be slidably connected to the slide rail 212 on the upright plate, and the slide rail 212 is vertically fixed on the upright plate.

[0029] Reference Figure 4 , Figure 6 and Figure 7 The drive cylinder 28 is mounted on the upright plate. The output end of the drive cylinder 28 is connected to the connecting seat 210 through the connecting bracket 29. Cams are set at the upper and lower ends of the connecting seat 210 and on the side facing the slider 211. A cam groove 213 corresponding to the cam is opened at the corresponding position of the slider 211. The cam groove 213 is inclined and the cam is slidably connected in the cam groove 213. When the drive cylinder 28 drives the connecting seat 210 to move laterally, the cam slides in the cam groove 213, which can drive the two sets of sliders 211 to move up and down along the slide rail 212, changing from lateral movement to up and down movement, thereby adjusting the distance between the two sets of rotating dust removal components 26 and the two sets of roller pressing components 25 to adapt to the different needs of the battery cells.

[0030] Reference Figure 5 The rotary dust removal assembly 26 includes a rotary dust removal component 261 mounted on a slider 211. The rotary dust removal component 261 has an outer cover, an inner brush, and a motor 264 connected to the brush at the top. The cover is connected to a negative pressure pipe 263. The motor 264 can drive the brush to rotate, and the brush can then clean the rolled battery cells. The generated dust is extracted from the negative pressure pipe 263, which is subsequently connected to a negative pressure device.

[0031] Reference Figure 5The rolling assembly 25 includes a roller assembly 251, and an angle detection sensor 253 is provided on the upper or lower part of the roller assembly 251; the roller assembly 251 includes rollers, which can subsequently perform rolling processing on the welding parts of the battery cell.

[0032] Example 2 Reference Figure 1 and Figure 2 This embodiment discloses a battery cell assembly system, including the roller pressing dust removal and detection mechanism 2 in embodiment 1, as well as a magnetic levitation circulating fixture 5 and a magnetic levitation stator mounting base 4. The magnetic levitation circulating fixture 5 is provided in several groups and is installed at equal intervals on the magnetic levitation stator mounting base 4; the roller pressing dust removal and detection mechanism 2 is provided in at least two groups and is located on both sides of the magnetic levitation production line respectively.

[0033] The magnetic levitation circulating fixture 5 includes a fixture base plate 51. The top two sides of the fixture base plate 51 are provided with clamping push blocks 53 that can fix the battery cell. The bottom of the fixture base plate 51 is provided with a magnetic levitation mover 52 that is connected to the magnetic levitation stator mounting base 4. The product 6 (i.e., the battery cell in this application) is mounted on the fixture base plate 51.

[0034] The specific operating principle of this application is as follows: The magnetic levitation circulating fixture 5 enters the roller pressing dust removal and detection mechanism 2 from the material receiving position of the circulating fixture in the previous process 1. At this time, the drive cylinders 28 on both sides extend, and the center distance between the rollers of the upper and lower roller pressing components 25 decreases. The magnetic levitation circulating fixture 5 passes through the upper and lower long side roller pressing dust removal and detection mechanism 2 on both sides at a uniform speed. At this time, the long side roller pressing components 25 on both sides have a pre-pressure on the weld seams of the upper and lower long sides of the battery cell. Under the action of the pre-pressure, the flanged weld seams after welding around the perimeter are rolled flat to ensure the overall thickness dimension of the battery cell.

[0035] The roller pressing assembly 25 can freely adjust the roller pressing contact angle with the product according to requirements, that is, the adjustment is indirectly achieved through the drive cylinder 28; after the roller pressing angle is set according to the process requirements and adjusted to OK, the position is locked. An angle detection sensor 253 is added to the upper and lower roller assembly 251 (see reference). Figure 5 This method ensures the consistency of the overall rolling angle during online roll forming. If an angle abnormality occurs, an alarm will be triggered immediately, and manual intervention will be required to make adjustments. This method guarantees the consistency of rolling and the quality of the product.

[0036] After rolling, the product continues to pass through the online upper and lower rotating dust removal assembly 26. This mechanism uses a brushless motor 264 to rotate a brush to remove dust from the upper and lower long sides of the rolled battery cell, preventing the dust or other debris from rolling from being carried into the next process to contaminate the battery and affect the processing of subsequent processes. The rolling and dust removal of the two large surfaces of the battery cell are completed during the battery cell's movement, which is a flying processing solution that greatly improves the process capacity and cycle time, and reduces the number of such workstations. The magnetic levitation circulating fixture 5 carries the battery cell forward and passes through the 3D contour meter detection component 24. The battery cell is inspected during the transport process, realizing online flight processing. In case of shift change or mechanism abnormality, the entire flight processing component can be cut off (i.e., transferred) to the off-line for maintenance and repair through the front and rear adjustment module 22 and the left and right adjustment module 23, which greatly improves the convenience of maintenance and repair. After the battery cell is rolled, dusted, and inspected by the 3D contour meter, the magnetic levitation circulating fixture 5 continues to move to the next workstation for processing, and the whole cycle repeats the above actions.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
