[0038] Generally, lithium batteries are transported by belts during production, and the only way to block the batteries at each workstation is by railings, that is, by a cylinder. Currently, there is a gas rotary clamping cylinder on the market, including a cylinder body, an upper cover and a bottom cover. The cylinder body is provided with a valve cavity, and a piston assembly is placed in the valve cavity. The upper cover is fixedly installed on the upper end of the cylinder body, and the upper cover is provided with a guide member that cooperates with the piston assembly.

[0065] In some embodiments, the present application provides a lithium battery handling device, comprising: Figures 1 to 4 The rotation blocking mechanism shown.

[0066] In some implementation scenarios, the rotation blocking mechanism provided in the embodiments of the present application is used for transporting and blocking lithium batteries; generally, in the prior art solutions, the guide groove and guide member of the piston rod are both inside the cylinder body, and the iron filings generated by its operation are all in the cavity, which cannot be maintained on a daily basis, and will affect the service life of the cylinder; at the same time, when the piston rod moves, in addition to horizontal movement, it will also rotate, which also reduces the service life of the sealing component of the cylinder;

[0067] For example, the rotation blocking mechanism provided in the embodiment of the present application is a long-life rotation blocking mechanism that is easy to disassemble and maintain and is installed on the side; in the process of lithium battery production and transportation, taking the pull belt transportation as an example, the use of the rotation blocking mechanism is as follows:

[0068] The rotation blocking mechanism is installed on one side of the drawstring. Under normal circumstances, the cylinder 500 is in a retracted state, and the blocking assembly 600 is parallel to the drawstring.

[0069] When the battery cell is carried to the position of the rotating blocking mechanism by the pull belt, it contacts the blocking assembly 600. At this time, the cylinder 500 is in a retracted state. The piston rod of the cylinder 500 is equipped with a rotating bearing 400 and is in direct contact with the rotating shaft 300. The elastic mechanism 700 is force-buffered, which can effectively reduce the impact force between the battery cell and the blocking assembly 600. The vertical displacement of the cam groove is greater than the cylinder stroke, so there will be no impact at the extreme position due to the cylinder stroke being in place.

[0070] When release is required, the piston rod of the cylinder 500 extends, forcing the rotating shaft 300 to slide in the cam body 100; since a cam follower (guide member 200) is installed at the bottom of the rotating shaft 300, the rotating shaft 300 is forced to perform linear and rotational motion along the guide groove of the cam body 100;

[0071] When the cylinder 500 is extended to the full position, the rotating shaft 300 rotates 90° while being extended to the full position, and the blocking assembly 600 and the pull belt are in a vertical state; at this time, the sensor (magnetic switch 810) installed outside the cam body 100 senses the magnetic ring 800 on the rotating shaft 300, and gives feedback that the rotating blocking mechanism is extended to the full position, and the battery cell is transported out of the blocking mechanism position through the pull belt.
