Detailed Description
As shown in fig. 1, 3 and 7, a lithium battery can-in system includes a claw insert and an aluminum can; the aluminum shell 1-3 is in clamping connection with the clamp claw 1-2, the clamp claw 1-2 is in control connection with the rotary controller 1-1, the clamp claw 1-2 pushes the aluminum shell 1-3 into the dust collection station 3, the clamp claw 1-2 pushes the aluminum shell 1-3 into the shell station 4, the shell station 4 is sleeved with the aluminum shell 1-3 through the alignment sleeve 4-3, the push plate 4-1 is arranged at the sleeved front end of the aluminum shell 1-3, the push plate 4-1 is in push connection with the electric core 4-4 through the retainer 4-2, and the electric core 4-4 is sleeved with the aluminum shell 1-3 through the Mylar film 4-5. The invention firstly conveys the prepared aluminum shell 1-3 to a dust collection station 3 through a clamp claw 1-2 for dust collection treatment. The lithium battery is ensured not to be polluted by dust in the installation process, so that the scrapping treatment of the lithium battery is avoided. After the dust removal process is completed, the empty aluminum shells 1-3 are transported to the shell entering station 4. The shell-in station 4 pushes the battery cell 4-1 with the retainer 4-2 into the aluminum shell 1-3 through the push plate 4-1. In order to prevent the cell 4-1 from being scratched by the metal aluminum case 1-3 during the pushing process, a layer of Mylar film 4-5 is thermally welded on the surface of the cell. Finally, the battery cell 4-4 is installed inside the aluminum shell 1-3.
As shown in FIG. 2, the dust collection station comprises a dust collection square tube 3-2, the dust collection square tube 3-2 is in sealing contact with an aluminum shell 1-3 through a rubber interface 3-1, a turbine fan 3-3 is arranged at the bottom of the dust collection square tube 3-2, and an exhaust shell 3-4 is sleeved at the outer end of the turbine fan 3-3. In the dust collection process, impurities and metal scraps remained on the inner wall of the aluminum shell 1-3 can be quickly and effectively sucked out by the turbine fan 3-3 and stored in the dustbin, so that secondary pollution is prevented.
As shown in fig. 4, the claw 1-2 pushes the aluminum shell 1-3 into the power-on detection station 5, the power-on detection station 5 comprises a moving plate 5-1, a moving electric meter box 5-4 is mounted on a sliding rail 5-3 of the moving plate 5-1, and a detection probe 5-2 on the moving electric meter box 5-4 is in detection contact with the positive electrode and the negative electrode on the retainer 4-2. In order to detect the lithium battery with the battery core 4-1 mounted, the positive and negative electrodes on the retainer 4-2 are detected by a detection probe 5-2. If an abnormality is detected, it is sent into the NG runner.
As shown in fig. 6, the jaws 1-2 push the aluminum shell 1-3 into the welding port of the laser welding device 7. The lithium battery detected by the circuit needs to be packaged to be processed in the next step, so that the aluminum shell 1-3 with the battery core 4-1 is sent into the laser welding device 7 for laser welding. During laser welding, the periphery is welded firstly, and then the middle part is welded, so that the phenomenon of shell air leakage in the welding process can be effectively prevented.
As shown in fig. 5, the claw 1-2 pushes the aluminum shell 1-3 into the shell outer dimension detecting station 6, the shell outer dimension detecting station 6 comprises a CCD detecting and placing table 6-3, the CCD detecting and placing table 6-3 is in limit connection with the aluminum shell 1-3, and the CCD detecting probe 6-1 at the top end of the CCD detecting and placing table 6-3 corresponds to the welding position of the aluminum shell 1-3 through the alignment hole 6-2. After the final welding is finished, the external dimension of the aluminum shell 1-3 is detected, the aluminum shell 1-3 is pushed into the shell external dimension detection station 6, the corner dimension is detected, the quality is finally separated, and the collection of finished products is finished.
After the CCD detection is completed, the aluminum shell 1-3 needs to be subjected to circuit detection to prevent unstable connection between the aluminum shell 1-3 and the retainer 4-2.
In conclusion, the multi-station technology for integrated molding can be used for rapidly and effectively producing lithium batteries in batches. In the production process, part of stations can be used for rapidly and effectively detecting the quality of the lithium battery, and meanwhile, poor-quality and high-quality lithium batteries are divided into flow passages in a high-efficiency mode.
