Abstract
Claims
1. A static mechanism for liquid injection of a cylindrical power battery, comprising a cylinder holder, characterized in that, The cylinder support is provided with an upper cylinder and a lower cylinder. The lower cylinder is provided with a transfer plate. The transfer plate is provided with a transfer conveyor line and a limiting component. The limiting component is located at the end of the transfer conveyor line. When the upper cylinder and the lower cylinder are engaged, they are fixed by a toothed structure.
2. The standing mechanism for liquid injection of a cylindrical power battery according to claim 1, characterized in that, The lower end opening edge of the upper cylinder body is provided with multiple engaging protrusions at intervals, and the inner edge of the lower cylinder body is provided with multiple limiting protrusions at intervals, with a tooth groove between every two limiting protrusions. The cylinder block support is also equipped with a lower cylinder block rotation control cylinder, which is located on the outside of the lower cylinder block, and the piston rod end of the lower cylinder block rotation control cylinder is connected to the outer side of the lower cylinder block.
3. The standing mechanism for liquid injection of a cylindrical power battery according to claim 2, characterized in that, The cylinder support is also provided with two lifting control cylinders for controlling the lifting and lowering of the upper cylinder. The piston rod ends of the two lifting control cylinders are connected to the lugs on the outside of the upper cylinder. The outer side of the upper cylinder is covered with a guide sleeve, which is connected to a guide rod, and the guide rod is mounted on the cylinder support.
4. The standing mechanism for liquid injection of a cylindrical power battery according to claim 3, characterized in that, When the upper cylinder body and the lower cylinder body are engaged, the engaging protrusion is inserted into the tooth groove. When the engaging protrusion is fully inserted into the tooth groove, the lower cylinder body rotation control cylinder controls the lower cylinder body to rotate a certain angle so that the engaging protrusion is located directly below the limiting protrusion, thereby restricting the movement of the upper cylinder body. When the upper cylinder body separates from the lower cylinder body, the lower cylinder body rotation control cylinder controls the lower cylinder body to rotate in the opposite direction by a certain angle, so that the engaging protrusion aligns with the tooth groove, and the lifting control cylinder controls the upper cylinder body to rise and open.
5. The standing mechanism for liquid injection of a cylindrical power battery according to claim 1, characterized in that, The cylinder block support is also equipped with a vacuum pipe and a pressurization pipe.
6. The standing mechanism for liquid injection of a cylindrical power battery according to claim 1, characterized in that, The transfer conveyor line includes two parallel roller mounting plates. The outer sides of both roller mounting plates are provided with outer side plates. Multiple rollers are arranged on both roller mounting plates and the two outer side plates. The height of the rollers on the outer side plates is greater than the height of the rollers on the roller mounting plates.
7. The standing mechanism for liquid injection of a cylindrical power battery according to claim 1, characterized in that, The limiting component includes a limiting bracket, on which multiple baffles and sensors are spaced apart; When the battery fixture moves to its limit position along the transfer conveyor line, the sensor detects the position of the battery fixture.
8. The standing mechanism for liquid injection of a cylindrical power battery according to claim 1, characterized in that, The upper end of the cylinder block support is also provided with a locking mechanism. When the upper cylinder block rises to its maximum height position, the locking mechanism locks the upper cylinder block.
9. The standing mechanism for liquid injection of a cylindrical power battery according to claim 1, characterized in that, The locking mechanism includes a locking cylinder and a locking fixing plate. The locking fixing plate is provided with two limiting plates, and the two limiting plates are provided with pin holes. The upper end of the upper cylinder is provided with a locking plate, and the locking plate is provided with a through hole. One of the limiting plates is provided with a position sensor. When the locking plate of the upper cylinder extends between the two limiting plates, the position sensor senses the locking plate, and the locking cylinder controls the piston rod to pass through the pin hole and the through hole.
10. The standing mechanism for liquid injection of a cylindrical power battery according to claim 1, characterized in that, The cylinder block support is also provided with a plurality of guide wheel assemblies at intervals, and the plurality of guide wheel assemblies are arranged along the circumference of the lower cylinder block; The guide wheel assembly includes a guide wheel bracket, on which a plurality of guide wheels are spaced apart, and the guide wheels are in contact with the outer side surface of the lower cylinder.
