[0034] In the process of detecting the battery cell, or in the transfer stage between multiple detection processes, etc., the movement of the battery cell is often required, and the target position of the battery cell also has different heights. The movement often causes the position of the battery cell to deviate, thereby affecting the subsequent process. Therefore, in the movement process, the prior art will align the battery cell, thereby ensuring the position of the battery cell.
[0035] On the other hand, in the process of aligning the battery cell, the battery or the battery cell is often impacted or pushed by the alignment mechanism to achieve alignment. The impact or pushing is easy to shake off the large particles of dust on the surface of the battery cell, and if these dusts are not treated, the subsequent process and the quality of the battery or the battery cell will be affected.
[0036] In order to solve the problem of battery cell dust falling caused by the alignment of the battery cell at present, the following will be combined with the accompanying drawings to specifically describe the present application. Figures 1-2 The present application is specifically described.
[0037] In order to solve the above problems, the present application provides an alignment device for aligning the battery cell 10.
[0038] The alignment device of the present application includes an alignment assembly 20 and a dust removal assembly 30. The alignment assembly 20 includes a telescopic piece 22 for pushing the battery cell 10. The battery cell 10 is located inside the dust removal assembly 30. The telescopic piece 22 is located inside the dust removal assembly 30 in whole or in part.
[0039] Specifically, the alignment device of the present application first pushes the battery cell 10 to the normal position state by the telescopic piece 22 of the alignment assembly 20. Then, the battery cell 10 is dusted by the dust removal assembly 30, thereby ensuring the cleanliness of the aligned battery cell 10.
[0040] The alignment assembly 20 can be provided with a pneumatic cylinder 21 at one end or both ends of the battery cell 10, and the piston rod of the pneumatic cylinder 21 is the telescopic piece 22. The alignment assembly 20 can also be a cam mechanism, and the telescopic piece 22 is a clamp or a push rod driven by the cam mechanism. The alignment assembly 20 can also be a mechanical structure such as a ball screw or a sliding rail mechanism, and the telescopic piece 22 is a screw rod or a sliding rail driven by a motor. The alignment assembly 20 can also be a spring positioning structure, or a structure of other flexible materials (such as elastic rods, flexible films), which is aligned by the self-adaptation of the spring, the elastic rod or the flexible film.
[0041] The alignment device of the present application is that the battery cell 10 is located inside the dust removal assembly 30. The telescopic part 22 is wholly or partially located inside the dust removal assembly 30. The alignment assembly 20 and the dust removal assembly 30 can be integrated design or separate design. When the alignment assembly 20 aligns the battery cell 10, the telescopic part 22 often needs to collide with the battery cell 10, and during the collision process, it is particularly easy to cause the large particle dust to fall off. The integrated design of the alignment assembly 20 and the dust removal assembly 30 improves the pertinence of dust removal and ensures the cleanliness of the battery cell 10. At the same time, the alignment accuracy is improved, and the stability of the subsequent process is improved.
[0042] In some embodiments, the alignment assembly 20 includes a gas cylinder 21, and the telescopic part 22 is a piston rod of the gas cylinder 21.
[0043] Specifically, in some embodiments, as shown in Figure 1 The gas cylinder 21 is arranged at the end of the battery cell 10, and by adjusting the stroke of the gas cylinder 21, the telescopic part 22 pushes the battery cell 10 to keep the running alignment state.
[0044] In the above technical solution, the design of the gas cylinder 21 simplifies the structure, enhances the stability and reliability of the alignment process, the precise control of the gas cylinder 21 improves the automation level of the alignment operation, and ensures the stable operation of the subsequent process.
[0045] In some embodiments, the dust removal assembly 30 includes an air suction shield 31 and a static electricity removal blower pipe 33, and the static electricity removal blower pipe 33 extends into the air suction shield 31.
[0046] Specifically, the static electricity removal blower pipe 33 releases ionized airflow by built-in or connected high-voltage static electricity generator or connected plasma device, can neutralize static electricity, and then blows away the dust particles attached to the surface of the battery cell 10 by compressed air.
[0047] In the above technical solution, the static electricity removal blower pipe 33 combines the airflow and static electricity neutralization technology, can realize the synchronous operation of static electricity removal and dust removal, and prevents the dust from re-attaching due to static electricity adsorption through the static electricity elimination function.
[0048] Preferably, in some embodiments, the battery cell 10 is located inside the air suction shield 31. The telescopic part 22 is wholly or partially located inside the air suction shield 31. Thus, the centralized treatment of dust particles is better realized, and the cleaning optimization of the battery cell 10 is realized.
[0049] In some embodiments, the dust removal assembly 30 further includes a plasma generator 32, and an emission gun of the plasma generator 32 extends into the air suction shield 31.
[0050] The plasma generator 32 generates a large number of positive and negative ions by ionizing air. The ions neutralize the static electricity on the surface of the battery cell 10 or the dust particles, thereby eliminating the static electricity. After the surface static electricity is eliminated, the dust particles lose the adsorption force and become easy to be blown away by external force (such as air flow). The plasma generator 32 can be connected to the air blowing structure, or connected to the air suction structure, or connected to both the air blowing structure and the air suction structure, to realize the cleaning of the dust particles.
[0051] In the above technical solution, the plasma generator 32 helps to accurately and efficiently remove the attached particles and static electricity on the surface of the battery cell 10. In addition to the large dust particles falling from the battery cell 10 due to the impact of the alignment assembly, the fine dust on the surface of the battery cell 10 is further removed from the surface of the battery cell 10 through neutralization reaction, thereby enhancing the cleaning effect and reducing the interference with the subsequent process.
[0052] In some embodiments, the dust removal assembly 30 includes an electrostatic blowing pipe 33 and a plasma generator 32. The electrostatic blowing pipe 33 and the plasma generator 32 are connected. The plasma generator 32 generates a large number of positive and negative ions by ionizing air. The ions neutralize the static electricity on the surface of the battery cell 10 or the dust particles, thereby eliminating the static electricity. After the surface static electricity is eliminated, the dust particles lose the adsorption force and become easy to be blown away by external force (such as air flow). The electrostatic blowing pipe 33 blows away the dust particles attached to the surface of the battery cell 10 through compressed air.
[0053] In some embodiments, the dust removal assembly 30 further includes an air suction pipe 34. The air suction speed of the air suction pipe 34 is 10 m / s-20 m / s.
[0054] The air suction pipe 34 is arranged in the air suction shroud 31 to suck the dust particles in the air suction shroud 31 away from the working area, thereby ensuring the cleaning of the battery cell 10.
[0055] The air suction speed of the air suction pipe 34 is 10 m / s-20 m / s, which is determined comprehensively according to the number of dust particles on the surface of the battery cell 10, the number of battery cells 10 in the air suction shroud 31, the alignment environment, the air suction efficiency, and the process in which the battery cell 10 is located.
[0056] In some embodiments, the air suction speed of the air suction pipe 34 is 15 m / s.
[0057] In the above technical solution, the air suction speed range can balance the air suction efficiency and the stability of the alignment environment, thereby effectively preventing the position deviation of the battery cell 10 due to air flow disturbance during the alignment process.
[0058] In some embodiments, the end surface of the telescopic member 22 is fixed with an Optigreen 23.
[0059] In the technical solution, the flexible contact surface provided by the super strong adhesive 23 can help avoid damage caused by hard contact when pushing the battery cell 10, protect the appearance of the battery cell 10, and prolong the service life of the device.
[0060] In some embodiments, the air cylinders 21 are two and symmetrically distributed at both ends of the battery cell 10.
[0061] When aligning, the distribution of the air cylinders 21 on both sides can make the two ends of the battery cell 10 be adjusted at the same time, so that the alignment is more flexible, the applicable range is wider, and the positioning speed is faster and more stable.
[0062] Specifically, the air cylinders 21 symmetrically distributed at both ends of the battery cell 10 provide more stable support and alignment force, improve the alignment accuracy, and reduce the influence of single-point stress on the battery cell 10.
[0063] In some embodiments, the piston rod end is fixed with a pushing surface 24, and the area of the pushing surface 24 is greater than or equal to the area of the end surface of the two battery cells 10.
[0064] The area of the pushing surface 24 is greater than or equal to the area of the end surface of the two battery cells 10, which can push multiple battery cells 10 at the same time, so that multiple battery cells 20 are aligned at the same time, improving the efficiency of alignment; at the same time, the area of the pushing surface 24 is large, which can make the pushing of the pushing surface 24 on the battery cell 20 more stable, ensure the uniform stress of the battery cell 10, and prevent damage or decrease in alignment accuracy of the battery cell 10 caused by uneven local stress.
[0065] In some embodiments, the present application provides a feeding assembly, as shown in Figure 1 .
[0066] The feeding assembly of the present application includes a battery cell transmission line body 40 and an alignment device of an embodiment of the present application, and the suction shroud 31 is provided with a through groove 35 for the battery cell transmission line body 40.
[0067] Through the arrangement of the through groove 35, the battery cell 10 on the battery cell transmission line body 40 can be aligned and dusted at the same time, and the transmission of the battery cell 10 by the battery cell transmission line body 40 is not affected.
[0068] In the technical solution, the feeding assembly of the present application can align and dust the battery cell 10 on the battery cell transmission line body 40 at the same time, improve the alignment accuracy, ensure the cleanliness of the battery cell 10, and thus improve the stability of the subsequent process after feeding.
[0069] In some embodiments, the present application provides a battery cell appearance detection system, which includes a feeding assembly and an end surface detection assembly of an embodiment of the present application.
[0070] In the technical scheme, the battery cell appearance detection system can realize the alignment of the battery cell 10 and the dust removal of the battery cell 10 at the same time during the feeding, improves the alignment accuracy, guarantees the cleanliness of the battery cell 10, and thus improves the stability of the subsequent end face detection process.
[0071] In the technical scheme, the above is only the preferred embodiment of the application and is not used to limit the application. For those skilled in the art, the application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
