Manual OCV Multifunction Test Sorting Machine

Product Overview

This system is a manual open-circuit-voltage testing and sorting solution for pouch lithium-ion prismatic cells. It combines OCV and internal-resistance measurement with data binding, software-based grade classification, and database upload. The operator receives a clear grade result after each completed test, creating a controlled manual workflow for separating cells according to defined voltage and resistance criteria.

The equipment is suited to lithium-ion cell manufacturing, cell inspection, pilot production, and laboratory workflows that require test data to remain associated with the inspected product. An operator manually loads a cell into the locating fixture, initiates the test through the light curtain, and places the completed cell into the appropriate grade tray after the system announces the result.

Built around an industrial control system, computer display, tester, test equipment, and software system, this unit supports consistent handling under routine production conditions. The measured data are displayed for review and uploaded to a database for retention, helping personnel identify abnormal products while maintaining a straightforward one-person operating process.

Key Features

• Integrated OCV and Internal-Resistance Grading: The equipment tests voltage and internal resistance, then uses upper-computer software to classify the cell data into grades. This brings measurement and sorting decisions into one manual workstation.

• Cell Data Binding and Database Upload: Test data are bound to the product and uploaded to the database through the industrial control system. The retained data support organized review of completed tests and grade results.

• Light-Curtain Test Start: A light curtain initiates the tester after the cell is positioned in the fixture. This provides a defined trigger point in the manual loading sequence before measurement begins.

• Operator-Directed Grade Output: After the tester completes its cycle and transfers data to the software system, the audio system announces the corresponding grade. The voice announcement can be disabled when an audible prompt is not required.

• On-Screen Test Data Review: The computer display presents product test data for direct operator review. This helps the operator recognize abnormal products during the grading process.

• Manual Loading with Simple Locating Fixture: Cells are manually placed on the fixture and manually removed after testing. The simple positioning fixture supports straightforward model changeover within the specified compatible cell-size range.

• One-Person Standard Configuration: The standard operating arrangement is designed for one operator. The workflow assigns loading, result recognition, and placement into the relevant blister tray to a single workstation role.

• Production-Oriented Throughput: The specified efficiency is at least 10 PPM, subject to manual loading speed and a stated 0.3 s test time. This makes the unit appropriate where controlled manual handling is required alongside rapid measurement.

• Defined Equipment Support Systems: The supplied system includes a computer system, tester, test equipment, and software system. These elements work together to display, classify, announce, and store the test outcome.

• Broad Pouch-Cell Dimensional Compatibility: The fixture accommodates specified cell length, width, total-length, tab-length, tab-spacing, and thickness limits. This allows the equipment to support a range of pouch lithium-ion prismatic cell formats without changing the core testing workflow.
