[0047] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0048] like Figure 1 As shown, a film-tearing leak detection device comprises a loading mechanism 1, at least one group of film-tearing mechanisms 2, a handling robot 3, at least one group of leak detection mechanisms 4 and a unloading robot 5, wherein the loading mechanism 1 is arranged on one side of the film-tearing mechanism 2, and is used to transfer the battery cells to the film-tearing mechanism 2; the film-tearing mechanism 2 is arranged on one side of the handling robot 3, and is used to remove the protective film on the battery cells; the handling robot 3 is arranged on one side of the leak detection mechanism 4, and is used to place the battery cells after the film-tearing into the leak detection mechanism 4; the leak detection mechanism 4 is arranged on one side of the unloading robot 5, and is used to perform leakage detection on the battery cells; the unloading robot 5 is used to unload the battery cells after the leak detection.

[0049] The workflow of this embodiment is as follows:

[0050] First, the loading mechanism 1 automatically transports the battery cells to the working area of ​​the film tearing mechanism 2, then the film tearing mechanism 2 clamps the battery cells and removes the protective film thereon, then the transport robot 3 transports the film-torn battery cells to the workbench of the leakage detection mechanism 4, then the leakage detection mechanism 4 performs a liquid leakage test on the battery cells and feeds back the test results to the control system, finally the unloading robot 5 transports the battery cells to the corresponding collection area or processing area according to the test results.

[0051] In this embodiment, the loading mechanism 1 includes a first support column 11, a loading transverse movement module 12 and at least one group of loading robots 13. The loading transverse movement module 12 is installed on the first support column 11, and the loading robot 13 is installed on the loading transverse movement module 12. The loading transverse movement module 12 is used to drive the loading robot 13 to absorb the battery cell and then move horizontally.

[0052] like Figure 2 As shown, in this embodiment, the loading robot 13 includes a first lifting drive device 131, a first lifting guide device 132, a first lifting buffer device 133 and a first suction cup device 134. The first suction cup device 134 is installed on the first lifting guide device 132 through the first lifting buffer device 133. The first lifting drive device 131 is used to drive the first suction cup device 134 to absorb the battery cell and then perform lifting movement along the first lifting guide device 132.

[0053] like Figure 2 As shown, in this embodiment, the first lifting drive device 131 includes a first motor 1311 and a first screw rod 1312 .

[0054] like Figure 3 As shown, in this embodiment, the film tearing mechanism 2 includes a clamp film tearing device 21, a first blowing device 22, a film tearing platform 23 and a waste film removal device 24. The clamp film tearing device 21 is arranged on one side of the first blowing device 22. The clamp film tearing device 21 is used to clamp the protective film of the battery cell blown up by the first blowing device 22. After clamping, the clamp film tearing device 21 tears the protective film from the battery cell. The film tearing platform 23 is arranged on one side of the clamp film tearing device 21 for fixing the battery cell. The waste film removal device 24 is arranged on one side of the film tearing platform 23 for clamping the protective film torn off by the clamp film tearing device 21 and removing the protective film.

[0055] In this embodiment, the protective film on the battery cell is first blown up by the first blowing device 22, so that a certain gap is formed between the protective film and the battery cell, which is convenient for the clamp film tearing device 21 to accurately clamp. This non-contact preliminary separation reduces the resistance during film tearing and improves the efficiency and success rate of film tearing. The clamp film tearing device 21 then accurately tears the protective film from the battery cell, ensuring the accuracy and consistency of film tearing.

[0056] The film-tearing platform 23 of this embodiment is used to stabilize and fix the battery cell, provide support during the film-tearing process, and prevent the battery cell from being deformed or damaged due to uneven force. This design protects the integrity of the battery cell and reduces the quality problems of the battery cell caused by improper film-tearing operation.

[0057] The waste film removal device 24 of this embodiment can automatically clamp and remove the torn protective film, effectively separating the waste film from the production line, facilitating the subsequent collection and treatment of the waste film. This design not only improves the cleanliness of the production line, but also reduces the pollution of the waste film to the production environment.

[0058] like Figure 7As shown, in this embodiment, the clip film tearing device 21 includes a film tearing XY-axis transverse movement module 211 and a film tearing clamp assembly 212. The film tearing clamp assembly 212 is arranged on the film tearing XY-axis transverse movement module 211. The film tearing clamp assembly 212 is used to clamp the protective film. The film tearing XY-axis transverse movement module 211 is used to drive the film tearing clamp assembly 212 to tear the protective film off the battery cell.

[0059] like Figure 3 As shown, in this embodiment, the film tearing clamp assembly 212 includes a film tearing clamp 2121 and a film tearing clamping driving device 2122, and the film tearing clamping driving device 2122 is used to drive the film tearing clamp 2121 to clamp the protective film.

[0060] like Figure 4 As shown, in this embodiment, the first air blowing device 22 includes a first air blowing nozzle 221 and a first air blowing mounting frame 222 , and the first air blowing nozzle 221 is mounted on the first air blowing mounting frame 222 .

[0061] like Figure 4 As shown, in this embodiment, the film tearing platform 23 includes a fixed vacuum adsorption module 231 and at least one group of movable vacuum adsorption modules 232. The movable vacuum adsorption module 232 is arranged on one side of the fixed vacuum adsorption module 231. The movable vacuum adsorption module 232 can arbitrarily adjust the distance between it and the fixed vacuum adsorption module 231 along the adjustment guide rail 233. The fixed vacuum adsorption module 231 and the movable vacuum adsorption module 232 are provided with vacuum suction cups for adsorbing battery cells. The movable vacuum adsorption module 232 can arbitrarily adjust the distance between it and the fixed vacuum adsorption module 231 along the adjustment guide rail 233. This design enables the film tearing platform 23 to adapt to battery cells of different sizes and shapes. By adjusting the position of the movable module, it can be ensured that the battery cells are stably and evenly adsorbed on the platform, thereby improving the versatility and flexibility of the equipment.

[0062] like Figure 5As shown, in this embodiment, the waste film removal device 24 includes a second blowing device 241, a first waste film removal clamp assembly 242, a second waste film removal clamp assembly 243 and a waste film collection box 244. The first waste film removal clamp assembly 242 is arranged on one side of the second waste film removal clamp assembly 243, the second blowing device 241 is arranged on one side of the second waste film removal clamp assembly 243, and the waste film collection box 244 is arranged below the second waste film removal clamp assembly 243. The first waste film removal clamp assembly 242 is used to clamp the protective film b. The protective film has a sticky surface b1 and a non-sticky surface b2, so as to assist the second waste film removal clamp assembly 243 in clamping the non-sticky surface b1 of the protective mold b. When the second waste film removal clamp assembly 243 releases the support of the protective mold, the protective mold is blown into the waste film collection box 244 through the second blowing device 241. The coordinated work of the first waste film removal clamp assembly 242 and the second waste film removal clamp assembly 243 makes the removal process of the protective film more efficient. The first clamping assembly clamps the protective film, providing a stable support point for the second clamping assembly, so that the second clamping assembly can more accurately clamp the non-sticky surface of the protective film, thereby more easily separating the protective film from the battery cell or other substrate. This synergistic effect reduces the resistance and time during the removal process and improves the overall efficiency. At the same time, the use of the second blowing device 241 can quickly blow the separated protective film away from the working area, avoiding pollution to the environment and interference with subsequent processes.

[0063] like Figure 5 As shown, in this embodiment, the first waste film removing clamping assembly 242 includes a first waste film removing clamping jaw 2421 and a first waste film removing driving cylinder 2422. The first waste film removing driving cylinder 2422 drives the first waste film removing clamping jaw 2421 to perform a clamping motion.

[0064] like Figure 5 As shown, in the embodiment, the second waste film removal clamping assembly 243 includes a second waste film removal clamping jaw 2431 and a second waste film removal driving cylinder 2432. The second waste film removal driving cylinder 2432 drives the second waste film removal clamping jaw 2431 to perform a clamping motion.

[0065] like Figure 8 As shown, in this embodiment, the transport robot 3 includes an X-axis lateral movement module 31 and at least one group of transport modules 32. The transport module 32 is installed on the X-axis lateral movement module 31. The X-axis lateral movement module 31 is used to drive the transport module 32 to move horizontally after absorbing the battery cell.

[0066] like Fig. 9As shown, in this embodiment, the leakage detection mechanism 4 includes a base plate 41, a sealing cover 42, a sealing cover lifting drive device 43, at least one layer of battery cell carrier 44, a mounting frame 45 and a sealing cover guide column assembly 46. The battery cell carrier 44 is arranged on the base plate 41 for placing the battery cells. The sealing cover 42 is arranged above the base plate 41 through the sealing cover guide column assembly 46. The sealing cover lifting drive device 43 is used to drive the sealing cover 42 to seal the battery cell carrier 44 on the base plate 41.

[0067] Leak detection process:

[0068] First, the sealing cover 42 is driven by the sealing cover lifting drive device 43 to descend, and the battery cell carrier 44 is completely sealed on the base plate 41. Subsequently, the vacuum pumping mechanism of the battery cell carrier 44 performs a vacuum pumping operation to remove the air in the sealing cover 42 and create a closed detection environment. Next, the pressure holding stage ensures that the pressure in the sealing cover 42 is stable and reduces external interference. Then, clean gas (such as nitrogen or helium) is introduced, which does not react with the electrolyte for detection purposes. Finally, gas detection means (such as mass spectrometers, sensors, etc.) are used to detect whether the air in the sealing cover 42 contains electrolyte molecules to determine whether there is a leak in the battery cell. Through vacuum pumping and pressure holding measures, as well as the introduction of clean gas for detection, the precision and accuracy of detection can be significantly improved, and tiny leaks can be effectively identified.

[0069] like Fig.10 As shown, in this embodiment, at least one battery cell placement slot 441 is provided on the battery cell carrier 44 , and specifically, the battery cell carrier 44 of this embodiment is provided with four battery cell placement slots 441 .

[0070] like Fig.10 As shown, in this embodiment, a through hole 442 is provided in the battery cell placement groove 441. The through hole 442 allows gas to flow freely, and when the battery cell leaks, the leaked electrolyte or other volatile substances can quickly diffuse to the external space of the battery cell placement groove 441 through the through hole 442. This helps the detection equipment to capture these leaked substances more quickly, thereby improving the sensitivity and timeliness of the detection.

[0071] The presence of the through hole 442 makes it easier for any residues, such as electrolyte, impurities, etc., in the battery cell placement groove 441 to be washed away or discharged through air flow during the cleaning process, thereby preventing these residues from causing secondary contamination to the battery cell carrier 44 or affecting the accuracy of subsequent detection.

[0072] like Fig.10 As shown, in this embodiment, a foam 443 is arranged in the battery cell placement groove 441. The foam 443 can also buffer and reduce the impact and vibration that may be generated by the battery cell during the placement and movement process to a certain extent, thereby protecting the battery cell.

[0073] like Fig.10 As shown, in this embodiment, the battery cell carrier 44 is provided with four layers, each layer of the battery cell carrier 44 is connected by a connecting column 444, and each layer of the battery cell carrier 44 is locked by a height adjustment locking member 445. The design of the height adjustment locking member 445 allows the user to flexibly adjust the spacing between the two layers of the battery cell carrier 44 according to the different sizes or requirements of the battery cells. This adjustability increases the versatility and adaptability of the device, making it compatible with battery cells of various specifications.

[0074] like Fig.10 As shown, in this embodiment, the height adjustment locking member 445 has a locking groove, and the height adjustment locking member 445 is locked to the side of the battery carrier 44 by passing the locking bolt through the locking groove. The locking bolt passes through the locking groove and is locked to the side of the battery carrier 44, ensuring the stability of the two-layer battery carrier 44 after the height is adjusted. This locking mechanism effectively prevents the battery carrier 44 from shifting or shaking during use, ensuring the stable placement of the battery.

[0075] like Fig.11 As shown, in this embodiment, the unloading robot 5 includes an XZ driving module 51 and at least one set of unloading suction cup assemblies 52. The XZ driving module 51 can drive the unloading suction cup assemblies 52 to move along the X-axis direction and the Z-axis direction.
