Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery production machines, in particular to a battery centrifugal two-sealing device. BACKGROUND

[0002] In the process of lithium battery production, the lithium battery needs to be subjected to formation treatment. Since gas is generated during the formation of the lithium battery, a final sealing process is required to first puncture the gas pocket of the lithium battery and then seal it after the gas is extracted.

[0003] The patent document with the application number 201921314185.8 discloses a lithium battery centrifugal sealing mechanism and a two-sealing machine. The machine frame is provided with a work station turntable. A cam divider for controlling the rotation of the work station turntable and a divider driving assembly for controlling the operation of the cam divider are arranged below the work station turntable. Four lithium battery centrifugal sealing mechanisms are evenly distributed on the upper surface edge of the work station turntable. An upper material loading station, a first centrifugal sealing station, a second centrifugal sealing station and a lower material unloading station are sequentially arranged along the periphery of the work station turntable. The puncture sealing mechanism is installed on the centrifugal turntable and can be driven to rotate by the centrifugal turntable. A DD motor is arranged below the centrifugal turntable for driving the centrifugal turntable to rotate. The application document drives the work station turntable to rotate by the cooperation of the cam divider and the divider driving assembly to realize the transfer of the lithium battery centrifugal sealing mechanism between different work stations. The DD motor drives the centrifugal turntable to rotate to drive the puncture sealing mechanism to rotate. The structure design requires one driving source to drive each of the work station turntable and the centrifugal turntable. Multiple lithium battery centrifugal sealing mechanisms require multiple driving sources. The puncture sealing mechanism needs to be arranged at a non-central position of the centrifugal turntable, which increases the size of the lithium battery centrifugal sealing machine, complicates the structure of the machine, increases the number of driving sources of the machine, and increases the cost of production and use. In addition, although the centrifugal turntable can drive the puncture sealing mechanism to rotate relative to the work station turntable to adjust the angle of the puncture sealing mechanism, since the puncture sealing mechanism is arranged at a non-central position of the centrifugal turntable, it is not convenient for the operator to maintain the external structure (sealing cavity, cavity opening cylinder, etc.) of the lithium battery centrifugal sealing mechanism and the internal structure (puncture sealing mechanism) of the lithium battery centrifugal sealing mechanism after adjusting the angle of the puncture sealing mechanism, which increases the difficulty of maintenance and reduces the efficiency of maintenance. When the operator maintains the puncture sealing mechanism, the centrifugal turntable is easy to rotate relative to the work station turntable, which is not conducive to the operator to perform maintenance work, further increasing the difficulty of the operator to maintain the machine.
