Inspection product description

With the popularity of electrical appliances, more and more homes and offices are using electrical equipment. As a component of electrical equipment, the fan blades of electrical appliances play a key role in electrical appliances. The fan blade is a tool for cooling and dissipating heat in electrical appliances. It can protect the electrical appliances during use and prevent wire burnouts and fires caused by overheating.

Inspection scope

1 The fan blade inserts are installed in the correct direction and are not covered by resin. (The wrong direction of the insert will cause the customer to be unable to install)
2. The numbers and text fonts on the fan leaf fan heart are complete (The incomplete font on the fan blade are considered as defective in appearance)
3. The DENSO font and rotation mark on the fan leaf fan heart are complete (Incomplete fonts and rotation marks on the fan blade are considered as defective in appearance)
4.No cracks, shrinkage and burrs on the outside of the feed hole on the fan core (Such defects will shorten the service life of the fan blades)
5. No whitening, foreign matter, and filling burrs on the front and back of the fan blade (Such defects will cause poor appearance and high dynamic balance)
6. No burning, insufficient filling, bumps and burrs at the resin joints of the outer ring of the fan blade. (Such defects will cause poor appearance and high dynamic balance)
7. No depression inside the ejection position of the ejector pin on the fan core (Such defects will cause poor appearance and high dynamic balance)

General status of the detection system

The overall equipment integrates mechanical mechanisms, visual optical hardware and detection system software. The normal detection speed is 4 per minute (because the equipment is dual-channel, this speed is the speed of the two channels together), and the equipment can realize 7*24 hours of operation , Which greatly improves production efficiency.

Electric fan blade inspection equipment, with 14 sets of high-pixel industrial cameras, double-station inspection, comprehensive inspection of fan blade appearance defects. After the system collects sample images, the image processing software is compared and analyzed with standardized samples to determine good and defective products. Online alarm for defective products, counting function can be realized after finished product detection, counting accuracy rate is 100%. The software will open the sample comparison standard, and the operator on the customer site can control the comparison accuracy and choose the accuracy standard most suitable for their own production conditions, thereby controlling the defect rate.

Inspection scope

1,The whole set of inspection equipment includes mechanical parts, visual electronic hardware and inspection system software. Both parties need to pre-determine the height of the conveyor line to facilitate the on-site equipment connection.

2,This equipment needs to determine the number of cameras to be used and the corresponding inspection content according to the final requirements of the customer. The following table is for reference only.

4,The counting function can be realized after the finished product is inspected, and the counting accuracy rate is 100%.

5,The testing equipment needs to be regularly maintained and cleaned during use (such as conveyor belt cleaning, camera cleaning, etc.). The testing equipment itself will not cause secondary pollution sources (such as debris, fine foam, etc.) to the tested samples.

6,Equipment schematic image

• Ø The equipment has an independent mechanical structure frame, and the operating table has a protective cover (plexiglass or carbon steel sprayed material) to ensure safety during the operation of the equipment.
• Ø All external motors and other components of the equipment have protective measures
• Ø The equipment is equipped with two emergency stop switches, one key to stop the equipment.
• Ø The equipment uses 220v two-phase power, and the equipment will be grounded during installation and debugging to prevent equipment leakage
• Operation module
• Ø Our equipment adopts dual-channel detection, that means it can detect two types of products at the same time.
• Ø The equipment is completed manually, that means the input of the equipment is manually placed at the inspection station, and then the equipment is started, after the product inspection is completed, the product is taken out, and the product is processed according to the inspection result.
• Ø One person completes all procedures of the equipment operation and loading and unloading.
