Visual inspection is to use machine instead of human eyes to measure and judge. Visual inspection refers to the conversion of the captured object into image signal through machine vision products (i.e. image capturing devices, divided into CMOS and CCD) and transmission to a dedicated image processing system. According to the distribution of pixels, brightness, color and other information, it is transformed into digital signals to determine and classify.
At present, in the field of CCD vision inspection, automatic inspection is mainly made for the appearance size and defects of products, so as to replace manual inspection. Its characteristics are: high efficiency, high accuracy, high accuracy! This kind of CCD vision detection technology has been widely used in various industries, such as: precision hardware, electronic components, magnetic materials, silicone rubber, plastic parts and so on.
At present, this kind of CCD vision detection technology can meet the detection of most products, but there is a technical path in the whole industry: only surface defects can be detected, but internal defects can not be detected!
Here is an example of a product:
Endoscopic Visual Detection Technology
This is a 27 mm, 12 mm long plastic parts, the factory mainly produces this product, daily output of 50,000, the output is good. At present, all of them are manual inspection, which can not cope with, so we want to find visual inspection equipment to replace manual inspection, so as to improve production efficiency and accuracy. Wang Gong, a technician of the company, had already found five manufacturers of Juejue testing equipment before he arrived at Sputac, which could not be detected by field tests. Maybe industry people will sneer at it. Such a simple defect in product appearance and size is a piece of cake! Then take a look at the following pictures and test requirements, and maybe you'll take back what you just said! uuuuuuuuuu
Endoscopic Visual Detection Technology
Round hole diameter: 3mm depth 10mm hole and rectangular mouth edge distance 7mm
Testing requirements: Whether the white metal sheet in the inner circular hole is complete or not.
Endoscopic Visual Detection Technology
Seeing the requirements of inspection, it is estimated that many manufacturers of visual inspection equipment are foolish. The technology of CCD appearance detection has been very mature indeed, and there is little difference between manufacturers of visual inspection equipment for more than 10 years. But endoscopy technology is a threshold, is it true that many manufacturers of visual inspection equipment. Because of this, Wang Gong found five manufacturers of CCD vision detection equipment to solve this problem.
Fortunately, through the introduction of friends, Wang Gong came to Shenzhen SPOTECK Technology Co., Ltd. With a skeptical attitude (Wang Gong thought that no company could detect internal defects) he took out samples and gave them to technicians for polishing test. With the effort of a cup of tea, the test plan has come out.

Endoscopic Visual Detection Technology
Endoscopic visual inspection technology has always been a technical access control in the visual inspection industry. Only by breaking through this bottleneck can we better solve customer needs and make contributions to the field of visual inspection. After the technical staff's day and night research, the current mastery of endoscopic visual inspection technology has solved several internal defect detection needs. After the market postgraduate entrance examination, Sputek is undoubtedly the first step in the field of visual inspection, worthy of the company's 15 years of precipitation!
