Solar Cell Panel Inspection

Solar cell panel inspection with Dalsa cameras
The increased global awareness on how alternative energy sources can make a considerable contribution to lowering the outlet of CO2 and other harmful emissions from energy production/energy consumption processes, has in recent years moved the solar cell industry from a pioneer and research related industry to becoming much more industrial in its approach to manufacturing.

The increased demand for solar cell panels now emerging from many different industries along with a growing number of solar cell manufactures has turned the industry towards higher-volume automated manufacturing, where product quality assurance has become a vital element in the production process.

Again, this has increased the demand for digital automated imaging inspection systems that will help ensure a high and uniform quality of the solar cell panels at the end of the production line.

By introducing automated imaging systems in the production process, solar cell manufactures will benefit from higher production yields and lower scarp values, and end-users will benefit from higher efficiency, longer life and lower maintenance costs of products and buildings where solar cell panels are an integrated part.

3D Calibration for Inspection
If one wants to precisely effect 3D measurement of industrial components, the non-contact measurement via stereo images is a good option. Specially for these purposes, the SOLVing3D GmbH (Garbsen near Hanover in Germany) has developed its camera system PrOMPT.stereo. This robust and compact hardware equipment can be used as a mobile measurement device, or alternatively it can be integrated in existing plants, e.g., for 100% inspection.

Handwritten Character Recognition in Packet Identification System
Eckelmann AG from Wiesbaden, Germany, has modernized the stock receipt of a big warehouse based on powerful standard components.
A descriptive example for modernizing an automated packet identification system is the warehouse storage of the mail-order house WITT Weiden, Germany. The OCR has to identify standard labels with handwritten characters by about 400 suppliers around the world. The identification rate must be higher than 96%. ECKELMANN AG,
Mainz, developed this application based on HALCON that perfectly fits to the existing environment and the existing proprietary inventory control system.


 
 
     
GigE camera with Halcon software spots solar cell defects

Driven by government-funded programs such as the German “100,000 Roofs” program, solar power is one of the
fastest growing alternative energy sectors in Europe. To achieve the maximum power output, the photovoltaic
devices used in solar cells must be manufactured as effectively as possible to produce highly efficient products.
Manual quality assurance is next to impossible as the fragile wafers are difficult to handle - even more so at the
high throughput rates required for production.

PCB Hole Location

This application required accurate location of hole on PCB for needle dispenser to fill with epoxy. The difficulty arises because of a cable that covers part of the PCB. The application made use of Halcon matching technology to do matching of the hole area and ignoring the cable area.

   
       

 

Pin Connectors Inspection

 

Getting the right quality control information can make the difference between a streamlined, cost-effective production line and one that is a money pit. For example, with certain types of connectors, a lock ensures that the connector doesn't disengage from its socket. A connector with a flawed or missing lock could disengagefrom its socket, with potentially serious results. Defective connectors have to be rejected on the production line. But without reliable, broad-coverage quality control information, defective connectors can easily be missed and passed on to distributors or customers. In the long run, the producer can suffer costly consequences.
