Abstract
Description
Technical Field
[0001] This application relates to the field of testing equipment technology, and in particular to testing equipment for peeling adhesive from power battery cells. Background Technology
[0002] In the new energy and energy storage industry, electric battery modules are the core components. Electric battery modules are usually carefully assembled from dozens of individual cells. The fit between the cells and the accuracy of their relative positions play a crucial role in the overall performance and safety of the battery module.
[0003] Currently, to ensure a tight fit between battery cells without relative displacement, the industry commonly uses double-sided tape between every two cells. In the actual production process, the previous station has already completed the first side of the tape application, while the current station removes the release paper from the other side. However, the existing production method has many problems. During the production process, the tape application process is always done manually, which leads to poor consistency in tape removal, misaligned edges, and easy wrinkling, thus affecting the bonding effect between battery cells and the overall quality of the battery module. Utility Model Content
[0004] To address the aforementioned issue of inconsistent adhesive removal quality, this application provides an adhesive removal testing device for power battery cells.

A connecting plate is fixedly connected to the bottom of the guide rail type lifting platform. A mounting frame is fixedly connected to the bottom of the connecting plate. Image analysis modules are mounted on both sides of the top of the mounting frame. A connecting block is fixedly connected to one side of the mounting frame. A frame is fixedly connected to the bottom of the connecting block. A drive cylinder is mounted on the top of the frame. Limit rails are fixedly connected to both ends of the frame.

[0007] Preferably, the image analysis module is electrically connected to the drive cylinder and is used to control the start and stop of the drive cylinder according to the visual detection result, thereby driving the movable block to slide along the limiting track.
[0008] Preferably, the mounting frame has symmetrical adjustment slots on both sides, and a long strip-shaped visual light source is installed between the two adjustment slots. The mounting frame is provided with fixing bolts, which pass through the mounting frame and lock the two ends of the visual light source.

[0012] In summary, this application includes the following beneficial technical effects:
[0013] 1. This utility model uses an image analysis module to acquire high-definition images of the adhesive surface of the battery cell in real time, and uses image processing algorithms to accurately identify the position and state of the tape edge.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0022] Reference Figure 1-5 This utility model provides a power battery cell adhesive tearing detection device, including a gantry frame 1. The top of the gantry frame 1 is equipped with a guide rail type lifting machine 101. The bottom of the guide rail type lifting machine 101 is fixedly connected to a connecting plate 102. The bottom of the connecting plate 102 is fixedly connected to a mounting frame 2. Image analysis modules 204 are installed on both sides of the top of the mounting frame 2. A connecting block 3 is fixedly connected to one side of the mounting frame 2. A frame 301 is fixedly connected to the bottom of the connecting block 3. A drive cylinder 302 is provided on the top of the frame 301. Limit rails 303 are fixedly connected to both ends of the frame 301. Movable blocks 304 are slidably connected to the surface of the limit rails 303. A gripper module 305 is fixedly connected to the bottom of the movable block 304. A clamping block 306 is fixedly connected to one end of the gripper module 305. A recycling box 402 is provided at the bottom of the clamping block 306.
[0023] After the equipment is started, the gantry frame 1 provides support for the overall structure. The guide rail type lifting platform 101 starts and drives the connecting plate 102 to move up and down through its internal drive mechanism, thereby adjusting the mounting frame 2 to the height suitable for battery cell testing. At this time, the battery cell with the first side adhesive applied is transported to the testing station. The image analysis module 204 (with visual inspection function) on the mounting frame 2 starts working, collecting and analyzing images of the adhesive application status of the battery cell (including whether the release paper has been removed, whether the adhesive is crooked, whether there are wrinkles, etc.) to confirm the adhesive application result. The image analysis module 204 transmits the adhesive application result information to the PLC (programmable logic controller). The PLC processes the information according to the preset program. If the adhesive application result meets the requirements or the adhesive removal operation is required, the PLC sends a command to the drive cylinder 302. The drive cylinder 302 moves and pushes the movable block 304 to slide along the limit rails 303 at both ends of the frame 301. The movable block 304 drives the gripper module 305 to move, and the gripper module 305 drives the clamping block 306 to open or close to perform the adhesive tearing operation.
[0024] The gripper module 305 generally consists of grippers, a drive unit, and transmission components. When the drive unit (such as a cylinder or motor) receives an action command, it starts and transmits the driving force to the grippers through transmission components (such as gears, racks, or linkages), causing the grippers to open or close, thereby realizing the gripping and releasing operation. The image analysis module 204 integrates image acquisition, processing, and analysis functions. During operation, it first captures images of the adhesive surface of the battery cell using an image acquisition device (such as a CCD camera), and then transmits the acquired image data to the processing unit. The gripper module 305 and the image analysis module 204 are existing technologies and will not be described in detail here.
[0025] In a preferred embodiment, the image analysis module 204 is electrically connected to the drive cylinder 302 and is used to control the start and stop of the drive cylinder 302 according to the visual detection result, thereby driving the movable block 304 to slide along the limit track 303.
[0026] The image analysis module 204 acquires high-definition images of the adhesive surface of the battery cell in real time and accurately identifies the position and state of the tape edge through image processing algorithms. When it is detected that the tape needs to be peeled off, a control signal is immediately sent to the drive cylinder 302. The cylinder piston rod extends and retracts precisely to move the movable block 304. The clamping block 306 automatically resets after completing the peeling action according to the preset trajectory.
[0027] In a preferred embodiment, the mounting frame 2 has symmetrical adjustment slots 201 on both sides, and a long strip visual light source 203 is mounted between the two adjustment slots 201. The mounting frame 2 is provided with fixing bolts 202, which pass through the mounting frame 2 and lock the two ends of the visual light source 203.
[0028] The adjustment slots 201 on both sides of the mounting bracket 2 allow for fine-tuning of the position of the elongated visual light source 203, and the fixing bolts 202 can lock the light source 203 in the optimal position; the light source 203 provides uniform lighting conditions, ensuring that the image analysis module 204 can clearly capture the details of the tape edge.
[0029] In a preferred embodiment, the bottom of the gantry 1 is provided with a frame 4, the top of the frame 4 is provided with a guide box 401, and the recycling box 402 is located at the bottom of the guide box 401.
[0030] The guide box 401 receives the release paper torn off by the clamping block 306, and the waste material slides down in an orderly manner to the bottom recycling box 402 for centralized storage by gravity.
[0031] In a preferred embodiment, the top of the mounting bracket 2 is provided with two observation ports 205, and the top of the observation ports 205 is provided with an image analysis module 204. The image analysis module 204 captures images perpendicular to the adhesive surface of the battery cell.
[0032] The observation port 205 at the top of the mounting bracket 2 provides an unobstructed vertical shooting channel for the image analysis module 204, ensuring that the captured images are free from perspective distortion.
[0033] In a preferred embodiment, the inner wall of the guide box 401 is provided with an inclined guide plate, the bottom end of which extends to the opening of the recycling box 402.
[0034] The inclined guide plate on the inner wall of the guide box 401 forms a smooth transition slope structure. After the torn release paper contacts the guide plate, it slides into the opening of the recycling box 402 along a predetermined path.
[0035] The foregoing description of the exemplary embodiments of the power battery cell adhesive tearing testing equipment provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
