Semi-automatic Electrolyte Filling Machine for Prismatic Cell

Overview

TOB-BZDP-2ZZG is a semi-automatic electrolyte filling machine designed for precise quantitative electrolyte filling of prismatic cell. It is a 2-station machine, small in size and can be operated in a glove box. The machine adopts a working principle that uses one set of jig (can install and disassemble 2PCS products at a time), the absorption mode of vacuum fist and then liquid injection, manual loading and unloading, optional manual weighing and scanning code, and one person operation. Its structure consists of a weighing and scanning code device (electronic scale, scanning gun), battery fixture, liquid injection mechanism, data storage system, and mechanical transmission and numerical control system. Work flow is: Vacuuming/charge Nitrogen gas/standing (vacuum strength, vacuum holding time, standing time, cycle times all can be set) → manual weighing and scanning code (before filling) → manual clamp battery → fixture automatic positioning and clamping → automatic vacuum pumping and liquid injection → nitrogen filling/standing/vacuum breathing circulation filling → manual discharge clamping, code scanning and weighing (after filling) (according to the sequence of code scanning and weighing before filling) → end of work (cycle work). Equipment overall dimensions: L860xW650xH950 mm. Weight: About 0.6 tons. Color: Sheet metal gray white, rack blue (customer provided color palette). Compressed air: 0.4-0.6Mpa, Gas flow: 100L/min. Vacuum source: vacuum degree -0.095Mpa. Design capacity of filling cup: MAX600G, product electrolyte retention ±1.5%. Filling port diameter of battery: 3-5mm. Nitrogen: 0-0.2Mpa. Power supply: AC220V. Power: 1.5KW. Efficiency max: 0.1PPM; total filling standing time within 20 minutes, the longer the time, the lower the efficiency. Activation: ≥95% (statistical data for continuous production of 24 hrs). Filling accuracy: ±3‰ (using empty case, each filling head does filling once, sampling once, sampling 20 times for each filling head). Qualified rate: ≥99% according to the tolerance of ±3‰. Suitable battery dimension: The demander shall provide the size requirements and drawings of the cover plate. TOB-BZDP-2ZZG is used for precise quantitative electrolyte filling of prismatic cells and is described as an important equipment for advanced electrolyte filling process of prismatic cell production. The machine is suitable for small-footprint installations and can be operated inside a glove box; it supports 2-station operation (installing/disassembling 2 pieces at a time) and is designed for one-person operation with optional manual weighing and scanning code before and after filling.
