  Application Scenarios

  01

  100% Inspection / Sampling Inspection Before Seed Shipment

  Detect cracks, surface scratches, edge chipping, dimensional deviations, etc., record quality data, and optimize production processes.

  02

  Incoming Seed Crystal Re-inspection

  Eliminate new defects generated during transportation and storage, reducing production risks.

  03

  Laboratory Seed Quality Assessment

  Provide accurate seed quality data support for new material R&D and special crystal preparation.

  04

  Use in Crystal Pulling Workshop for Ingot Production

  Fast and accurate inspection before loading the seed into the crystal puller, preventing failures such as ingot breakage or polycrystalline inclusions during the pulling process.

  Functions

  ①

  Defect Detection

  Detect internal cracks (invisible to the naked eye) and surface defects in seeds: surface cracks, scratches, crescent marks, edge chipping, processing marks, etc.

  ②

  Dimension Measurement

  Precise measurement of large-end diameter, small-end diameter, taper, and length.

  ③

  Seed Code Recognition

  Automatically identify codes on seeds for traceability.

  ④

  Seed Stress Analysis

  Analyze internal stress distribution in seeds to prevent breakage during crystal pulling.

  ⑤

  Automatic Feeding Interface

  Reserved interface for automatic feeding to enable automated loading.

  ⑥

  MES Interface

  Reserved MES interface for data upload.

  Technical Advantages

  A

  No Blind Spots in Infrared Detection

  Adjusts the camera angle to fill the blind spot in the traditional method at the seed's tapered neck, capable of identifying multiple defects.

  

  

  B

  High-Resolution Camera + High-Parallelism Light Source

  Adopts a parallel optical scheme to eliminate specular reflection, resulting in sharp edges and high dimensional measurement accuracy.

  

  

  C

  One-Key Switch Between Pre- and Post-Acid Washing

  The high dynamic range infrared camera easily switches detection modes for both pre- and post-acid washing processes.

  D

  Proprietary Stress Detection

  Detects stress distribution in seeds to prevent breakage caused by excessive stress during crystal pulling.
