[0026] The 18650 lithium battery casing machine cap anti-rust automatic oiling device adopts the above structure, by placing the lithium battery at the feed port of the conveyor 2, and being conveyed to the bottom of the oiling mechanism by the conveyor 2, the oil in the first oil storage tank flows along the oil guide pipe 6 into the second oil storage tank 8, and then flows into the oiling part 5 along the oil leakage hole 11, and finally is smeared to the upper cover end of the lithium battery by the oiling part 5, the lithium battery is covered by the capping machine 3 after being oiled by the oiling part 5, and then the outer part of the lithium battery is covered with a plastic film by the coating machine 4, the device can apply oil to the upper cover of the lithium battery to prevent the lithium battery from being piled up in the warehouse for a long time, and the surface of the cap is damp and rusted, which solves the problem that after the traditional casing machine is completed, the unoiled lithium battery is left in the warehouse for a long time, and the surface of the lithium battery cap is easily damp and rusted, which affects the appearance at the least and affects the use of the lithium battery at the worst.

[0027] In this embodiment, an isolation plate 9 is fixedly provided in the second oil storage tank 8, and the isolation plate 9 divides the second liquid storage tank into an oil storage cavity 1 81 and an oil storage cavity 2 82. A flat liquid hole 10 is opened on the isolation plate 9, and the flat liquid hole 10 can connect the oil storage cavity 1 81 and the oil storage cavity 2 82. The second liquid storage tank is divided into the oil storage cavity 1 81 and the oil storage cavity 2 82 by the isolation plate 9, so that the oil can be evenly absorbed by the oiling part 5, and by setting the flat liquid hole 10, the oil in the oil storage cavity 1 81 and the oil storage cavity 2 82 can be kept level, and one side of the oiling part 5 will not contact the upper cover end of the lithium battery multiple times, thereby causing the oil in one of the oil storage cavity 1 81 or the oil storage cavity 2 82 to be exhausted while the other has remaining oil, affecting the uniformity of the coating.

[0028] In the present embodiment, there are two oiling parts 5, both of which are fixed at the bottom of the second oil storage tank 8, and are respectively connected to the oil storage cavity 1 81 and the oil storage cavity 2 82. By setting two oiling parts 5, the upper cover end of the lithium battery can be oiled twice, further increasing the uniformity of the coating.

[0029] In this embodiment, the oiling part 5 is made of sponge material. By setting the oiling part 5 to be a sponge material, it has the characteristics of water absorption, softness, elasticity, etc., can quickly absorb oil, and its softness will not cause wear to the upper cover end of the lithium battery. Its elasticity also allows the oiling part 5 to be quickly reset.

[0030] In this embodiment, a liquid separator 12 is also included. The liquid separator 12 is arranged between the connection between the oil guide pipe 6 and the second oil storage tank 8, and is fixed to the body of the cover upper machine 3. A three-way hole 13 is arranged in the liquid separator 12. One of the three-way holes 13 is connected to the oil guide pipe 6, and the other two holes face downward to the second oil storage tank 8. By setting the liquid separator 12, the oil is evenly transported to the oil storage cavity 1 81 and the oil storage cavity 2 82.

[0031] In this embodiment, an opening is provided at the top of the second oil storage tank 8, and oil inlet pipes 14 are fixed on the two holes in the liquid dividing member 12 facing the second oil storage tank 8. The two oil inlet pipes 14 are respectively directed to the openings of the oil storage cavity 1 81 and the oil storage cavity 2 82. By providing the oil inlet pipes 14, the oil is transported along the top opening of the second oil storage tank 8 to the oil storage cavity 1 81 and the oil storage cavity 2 82 of the second oil storage tank 8 through the oil inlet pipes 14. If the oil needs to be replaced, the staff can extract the oil through an external tool such as a syringe to replace it.

[0032] In this embodiment, a flow limiter 15 is installed on the oil guide pipe 6, and the flow limiter 15 can adjust the flow rate of the liquid in the oil guide pipe 6. By setting the flow limiter 15, the flow rate of the oil in the oil guide pipe 6 can be adjusted, thereby preventing the oil from overflowing the second oil storage tank 8.

[0033] Working principle: The lithium battery is placed at the feed port of the conveyor 2 and conveyed to the bottom of the oil coating mechanism by the conveyor 2. At the same time, the oil in the first oil storage tank flows into the liquid separator 12 along the oil guide pipe 6, and the oil flows into the three-way hole 13 of the liquid separator 12, so as to be evenly transported to the oil storage cavity 1 81 and the oil storage cavity 2 82, and then flows into the two oiling parts 5 along the oil leakage hole 11 and is absorbed by the oiling parts 5. Finally, when the lithium battery is conveyed by the conveyor 2, the upper cover end of the lithium battery is contacted by the oiling part 5, so that the upper cover end of the lithium battery is oiled. After that, the oiled lithium battery is pressed and fixed on the battery cover by the cover machine 3, and then the coating machine 4 covers the outside of the lithium battery with plastic. The material film is formed, thereby completing the oiling, covering and sleeve filming of the lithium battery, effectively preventing the lithium battery from being piled up in the warehouse for a long time and the surface of the cap from being damp and rusted. In the oiling process, since the isolation plate 9 is provided with a flat liquid hole 10, the oil in the oil storage cavity 1 81 and the oil storage cavity 2 82 can be kept balanced. When it is necessary to adjust the flow rate of the oil guide pipe 6, the flow rate of the oil in the oil guide pipe 6 can be adjusted by the flow limiter 15, thereby preventing the oil from overflowing the second oil storage tank 8. When it is necessary to replace a different oil for application, the staff can use an external tool syringe to evacuate the oil in the oil storage cavity 1 81 and the oil storage cavity 2 82, and close the oil guide pipe 6 through the flow limiter 15 for replacement.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
