Hardware appearance defect detection

The detection content of hardware appearance detection equipment includes the detection of sand holes and scratches on the polished surface of hardware; Identify and detect the mimeographed, silk-screen or pad printing character information on hardware.

Hardware appearance detection solution

In the hardware processing industry, customers have increasingly high requirements for hardware processing products, manufacturers using the traditional manual detection method will not only increase the cost of enterprises, but also difficult to ensure that the product quality requirements.

With the continuous innovation of technology, machine vision has entered the enterprise. Machine vision system is equipped with high-resolution industrial cameras and combined light source visual inspection system, which can meet customers' requirements for high-precision inspection of products, and improve the applicability of equipment according to various characteristics of products. Hardware appearance testing equipment provides a set of representative general and standardized reference solutions to solve the product appearance testing problems in the hardware industry. The detection contents and performance characteristics of hardware appearance detection equipment are as follows:

1.Detect the sand holes and scratches on the polished surface of the hardware; Identification and detection of mimeographed, silk-screen or pad printing character information on hardware, including: unclear, incomplete, uneven thickness of the character, character printing, etc.

2.Detection requirements: poor sand hole area and scratch length;

3.Detection speed: camera shooting time and visual detection time;

4.Reserved developable capability: character/bar code;

5.Auxiliary functions: provide sand surface brightness data collection; Reading, size/Angle measurement, shape detection, color difference recognition;

6.The equipment adopts semi-automatic feeding, automatic detection and automatic elimination of defective products.

In the process of parts processing, the size of the parts must be measured to judge whether the workpiece is qualified. The workpiece is detected by the machine vision system, the size of the workpiece is observed through the image obtained after enlarging the image, and the image measurement software is used to automatically measure the parts to be measured, in order to determine whether the processing meets the requirements.

Part measurement and detection system software based on machine vision image processing technology adopts regional selective automatic measurement. The dimensions are calibrated by measuring the scale before the parts are measured. In the measurement process, select the area to be measured through the mouse frame, and then click the measurement button to automatically identify the edges in the frame and measure the distance between the edges, which is the actual size after conversion.

For most manufacturing companies, their production automation is becoming more and more high, and the requirements for product quality and production efficiency are becoming more and more strict. The use of machine vision system can achieve stable, continuous and reliable product testing, overcoming the shortcomings of manual testing, such as easy fatigue, individual differences and poor repeatability, it can help companies to improve product quality, improve production efficiency and reduce production costs. With the development of manufacturing industry, machine vision will be further developed and widely used.
