Automatic Cell IV EL Sorting Integrated Machine

I. About the IV EL Sorting Integrated Machine

• Equipment Name: Solar Cell EL and Power Automatic Sorting Machine
  (This advanced equipment is not only an IV EL Sorting Integrated Machine but also incorporates the latest techniques in IV Testing and EL Testing for automated solar cell evaluation.)

• Model: YH-ZDFX-2400 -- IV EL Sorting Integrated Machine

• Overall Installation Dimension Diagram:

• (Refer to the provided diagram for detailed layout specifications – the system is engineered for seamless operation on a high-performance Solar Panel Production Line.)

II. Applicable Cell Information

• Polycrystalline and monocrystalline solar cells with dimensions ranging from 156mm to 220mm

• Warpage ≤ 3mm

• 2 to 6 busbars, 9 busbars

• Flat A-grade cells (with a yield rate of over 98%)

This IV EL Sorting Integrated Machine will be used for testing qualified products. 

III. Key Performance and Technical Parameters

1. Capacity:

   • Actual reference operating speed: 2200 pieces per hour

   • Average speed is approximately 1.6 seconds per piece

   • Note: This does not include the time for retrieving and unloading solar cells and changing the loading trays. Speed may be affected by factors such as inspection items and accuracy.

2. Breakage Rate:

   • ≤ 0.05% (This parameter refers to breakage caused by the machine itself, excluding material breakage.)

3. False Judgment Rate:

   • Approximately 6% (The specific ratio will be determined through negotiation depending on Party A’s process and inspection standards.)

   • Calculation: The number of A cells mistakenly judged as B divided by the number of cells selected by the machine.

4. Missed Judgment Rate:

   • ≤ 0.3% (The specific ratio will be determined through negotiation depending on Party A’s process and inspection standards.)

   • Calculation: The number of B cells missed by the machine divided by the number of cells selected by the machine.
