[0019] Reference Figure 1-Figure 2 A parallel lifting device for an energy storage type sealing and welding machine includes an upper electrode guide rod 8, an upper electrode seat 10, a bracket 9, a servo motor drive mechanism and a cylinder drive mechanism. The servo motor drive mechanism and the cylinder drive mechanism are both arranged on the upper electrode seat 10, and the upper electrode seat 10 is arranged on the bracket 9. The output end of the servo motor drive mechanism and the output end of the cylinder drive structure are both fixedly connected to the upper electrode guide rod 8.

A lower electrode assembly 6 is fixedly connected to the bracket 9, and the lower electrode assembly 6 is located below the upper electrode assembly 5.

[0020] The servo motor drive mechanism and the cylinder mechanism are connected in parallel to jointly drive the lifting movement of the upper electrode assembly. The electric lifting mechanism has three functions: the first is to stop the upper electrode assembly at an accurate position to facilitate machine vision detection of the material state; the second is to allow the upper electrode assembly and the lower electrode assembly to achieve a soft landing without impact on the welding material; the third is that the lifting speed of the upper electrode can be controlled by program and steplessly regulated. The role of the cylinder mechanism is to provide sufficient, stable and accurate welding pressure for welding.

[0021] The cylinder rod and the upper electrode guide rod are combined into one, which greatly improves the transmission accuracy. Adjusting the pressure in the upper chamber of the cylinder can accurately control the welding pressure between the upper and lower electrodes.

[0026] The working principle and use process of this utility model:

[0027] First, move the upper electrode to the upper end, then place the material tube holder on the lower electrode assembly, and the material tube cap on the upper electrode assembly. The lower chamber of the cylinder is connected to the atmosphere, and the upper chamber is connected to the atmosphere; the servo motor drives the upper electrode assembly to move downward and move to the appropriate position.
