Inspection principle

With the development of the market, the demand for consumer electronics and other products has greatly increased in recent years, and the demand for small hardware parts has also increased rapidly. The greatly increased production demand poses two major problems for inspection - how to efficiently complete the inspection and measurement of large quantities of parts? How to effectively avoid human measurement errors?

In the production process of hardware, some appearance defects will inevitably occur, such as lack of material, cracks, burrs, scratches, bumps, etc. These large or small defects sometimes not only affect the appearance, but also may affect the appearance. to the proper performance and safe operation of the entire device.

Inspection details

By adopting a hardware inspection and screening machine based on machine vision inspection technology, the factory conducts a comprehensive inspection of various appearance defects of the workpiece and eliminates defective products, which can avoid misjudgments and missed inspections in manual inspections, and improve production efficiency and product quality. The hardware detection and screening machine is composed of an automatic feeding system, a transmission positioning system, an automatic measuring system, an automatic sorting and blanking system, a measurement and control system, and a computer data processing system, which can automatically detect various types of hardware. Its workflow is as follows:

• The hardware is arranged in an orderly manner through a vibrating plate and a conveyor belt, and is transported to the front end of the linear track, and then enters the rotating glass plate;
• The glass plate runs to bring the hardware under the camera to take pictures;
• The photos are transmitted to the vision software system developed by Haotianchen Technology for high-speed, high-precision, high-stability real-time detection, analysis, and calculation, to detect specific defects and distinguish good and bad products.

Application range

• Connector appearance inspection: measurement of PIN diameter, PIN distance and other dimensions.
• Capacitor appearance inspection: capacitor size, pin diameter, etc.
• Inductor appearance inspection: measure length, width and other dimensions to detect surface defects.
• Appearance inspection of resistors: scratches, cracks, scorch, dimension measurement, etc.
• PIN needle appearance inspection: PIN needle spacing, offset, shortage, etc.
• Transformer appearance inspection: measure PIN diameter, PIN distance, row distance and other dimensions, and detect appearance defects such as desoldering, scorching, and poor pins.
• Wafer size and appearance defect detection: Wafer size measurement, accuracy ±0.001mm, wafer positive and negative coaxiality detection;
• The system controls the equipment actions on site according to the results of the judgment, and the defective products are automatically eliminated.

Features of system

Humans have subjective emotions, and their spirits will be fatigued, which will affect the detection results, but machines will not. It can work 24 hours a day and ensure accuracy; the human eye cannot detect subtle defects, but machine vision can quickly detect micron-level defects. The application of machine vision inspection is very necessary, especially for precision hardware inspection.

Machine vision inspection technology is widely used in the production inspection process of various industries. It greatly reduces the misjudgment rate, improves production efficiency and product quality, and also improves the level of production automation and reduces the labor cost of enterprises.
