Popularize CCD industrial camera application knowledge

High-precision automatic dispensing machines and glue filling machines are equipped with CCD industrial cameras, which can magnify products hundreds of times, a thousand times, or even ten thousand times. Some products have very small dispensing points and very high dispensing accuracy requirements. If you use your eyes to identify the dispensing points, on the one hand, the error will be very large, and the products you point out may not meet the quality requirements. On the other hand, if you look at them for too long, the dispensing points will feel blurry, and the work efficiency will be very low. More importantly, it is equipped with a CCD industrial camera and related CCD system software. When there is an error in the product workpiece, within a certain range, the automatic glue dispensing machine and automatic glue filling machine can automatically correct the position deviation.

Definition: Industrial cameras refer to camera equipment that can be used in industrial sites. They have the requirements to adapt to complex industrial environments and can work stably for a long time. Industrial cameras refer to video image acquisition equipment that can be stably and efficiently used in industrial sites. They can store images directly on hard disks. Compared with ordinary cameras, industrial cameras are highly comparable in terms of resolution, frame rate, light requirements, exposure methods, etc. The main component is a CCD photosensitive chip.

CCD was invented by Bell Laboratories in the late 1960s. Beginning as a new type of PC memory circuit, CCDs soon had many other potential applications, including signal and image (silicon's photosensitivity) processing.

CCD handles a series of different functions on a thin silicon wafer. Several identical ICs and other components that can produce functions are distributed on each silicon wafer. The selected IC is cut from the silicon wafer and packaged in a carrier for use in the system. To sum up, CCD mainly has the following types:

1. 1. Area array CCD industrial camera:

   Allows photographers to capture moving objects in a single exposure at any shutter speed.

2. 2. Line array CCD industrial camera:

   An image is scanned using a row of pixels and three exposures are made - one for red, green and blue filters. As the name suggests, linear sensors capture one-dimensional images. It was initially used in the advertising industry to shoot static images and linear arrays. When processing high-resolution images, it was limited to non-moving objects with continuous lighting.

3. Three, three-line sensor CCD industrial camera:

   In a three-line sensor, three parallel rows of pixels cover RGB filters respectively. When capturing a color image, the complete color image is composed of multiple rows of pixels. Three-line CCD sensors are mostly used in high-end digital cameras to produce high resolution and spectral gradation.

4. 4. Interleaved transmission CCD industrial camera:

   This sensor utilizes separate arrays for image capture and power conversion, allowing the current image to be read while the next image is being captured. Interlaced transmission CCDs are commonly used in low-end digital cameras, camcorders, and broadcast cameras that shoot animations.

5. 5. Full-frame CCD industrial camera:

   This kind of CCD has more power processing capabilities, better dynamic range, low noise and transmission optical resolution. The full-frame CCD allows instant full-color pictures. The full-frame CCD consists of parallel floating-point registers, serial floating-point registers and signal output amplifiers. Full-frame CCD exposure is controlled by a mechanical shutter or gate to save the image, and a parallel register is used for metering and reading metering values. The image is projected onto a parallel array that serves as a projection screen. This element receives the image information and divides it into discrete quantized elements determined by the number. These information flows from parallel registers to serial registers. This process is repeated until all information is transferred. Next, the system performs precise image reconstruction.
