Lab Semi-auto Prismatic Cell Stacker Stacking Machine For Battery Research

1. Functional Overview

The equipment is primarily designed for assembling the positive and negative electrode sheets along with separator layers into a Z-fashion stacking configuration to construct the battery cell. The left and right material picking robotic arms retrieve the electrode sheets from the positive and negative material hoppers. Following precise secondary positioning on the positioning platform, they alternately place the sheets on the stacking platform. The stacking platform moves left and right in coordination with the two robotic arms' actions, with the separator forming a Z-fashion to isolate the positive and negative electrode sheets. This cyclical action by the equipment accomplishes the stacking assembly of the electrode stack.

1. Electrode Sheet Configuration:

- Both positive and negative electrode sheets are configured with material magazine.

- The electrode sheets in the working material box have a real-time floating structure.

2. Secondary Positioning Mechanism:

- A secondary positioning mechanism is provided for the positive and negative electrode sheets, ensuring precise positioning.

3. Sheet-Picking Mechanical Arm:

- Utilizes a high-speed linear servo module set for stable and reliable vacuum picking and placing of materials.

- Switches positions between the material box, secondary positioning platform, and stacking platform.

- Positive and negative electrode sheet-picking mechanical arms alternately place materials.

4. Separator Unwinding Mechanism:

- Uses precise semi-closed loop control with continuously adjustable working tension.

- Equipped with an alignment correction mechanism.

5. Stacking Platform Mechanism:

- Features a precise guiding mechanism allowing real-time adjustment according to the thickness of the stacked sheets, accommodating different cell thicknesses.

- Driven by a high-speed linear servo module set for high-speed, precise, and stable reciprocating movement between the positive and negative electrode sheets.

- Cylinder-driven pressing claw performs X-Y bidirectional composite movements to press and position electrode sheets and separators, achieving the Z-shaped stacking process for lithium battery cells.

6. Electrical Control System:

- Centered on a PLC program controller.

- Uses set times, pressure, and position sensors as control signals to drive motors, directional valves, cylinders, and other actuators, automatically switching to complete the workflow.

7. Human-Machine Interface:

- Facilitates interaction, allowing operation settings and the display and feedback of various machine information.
