Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of defect detectors, it is recommended to prioritize evaluating key technical parameters such as detection accuracy, resolution, and applicable material range to ensure that the equipment meets the actual production line requirements.
  • In metal processing or electronic component manufacturing scenarios, defect detectors need to be adapted to high-speed assembly line operations and support automatic recognition of common defects such as surface scratches and cracks.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure the stability of long-term cooperation.
  • For different industries such as automotive parts or photovoltaic module testing, algorithm compatibility and environmental adaptability (such as dust and vibration resistance) of defect detectors may become key considerations.

Knowledge Base

Q

Definition and Principle Visual defect detector is an automated detection device based on machine vision technology, which uses industrial cameras, light sources, and image processing algorithms to perform non-contact detection of surface or internal defects in products. The core principle is to collect images of target objects, analyze image features (such as color, texture, shape) using algorithms, and compare them with standard templates to identify them

Q

EL defect detector is a detection device based on the principle of electroluminescence, applied to the internal defect detection of photovoltaic solar panels, which can better help users complete product quality inspection and control production and installation risks. It can be widely used in the production, quality inspection, and power station operation and maintenance of solar cells and modules.
