Description
Technical Field
The invention relates to an SMT multi-view synchronous acquisition device.
Background
The light sensing element (light sensing Sensor) is the core of the digital camera and is also the most critical technology. The development of digital cameras is a development of light-sensitive elements. The core imaging components of the digital camera are two types: one is a widely used CCD (charge coupled) element; the other is a CMOS (complementary metal oxide conductor) device. Compared with the traditional camera, the traditional camera uses 'film' as a carrier for recording information, and the 'film' of the digital camera is an imaging photosensitive element of the digital camera, and the photosensitive element is the 'film' of the digital camera which is not replaced and is integrated with the camera, so that the heart of the digital camera is very definite.
There are two main types of photosensitive elements (photosensitive sensors): CCD (charge coupled), CMOS (complementary metal oxide semiconductor). As a new type of shooting function of a mobile phone, a built-in digital camera function is the same as a low-end (10 ten thousand to 130 ten thousand pixels) digital camera which is seen at ordinary times. The light sensing elements of digital cameras in most cell phones are essentially CMOS. The photosensitive element is also called an image sensor. It is made of a high sensitivity semiconductor material and consists of many photosensitive units, usually in mega-pixels. When the surface of the CCD is irradiated by light, each photosensitive unit reflects charges on the assembly, and the movable optical anti-shake (CCD anti-shake) photosensitive element of the photosensitive element converts the light into the charges; the signals generated by all the photosensitive units are added together to form a complete picture. Then converted into digital signals, compressed and stored in a flash memory or a built-in hard disk card inside the camera. Companies with the ability to produce CCDs are: sony, philips, kodak, songwa, fuji, sharp, mostly japan manufacturers. CMOS, like CCD, is a semiconductor that can record light changes in digital cameras. The CMOS manufacturing technology is not different from that of a common computer chip, and mainly utilizes a semiconductor made of two elements, namely silicon and germanium, so that N (band-electric) and P (band + electric) level semiconductors coexist on the CMOS, and the current generated by the two complementary effects can be recorded and interpreted into an image by a processing chip. However, CMOS has the disadvantage that it is too prone to heterospotting. In addition to the CCD and CMOS, there is the SUPERCCD exclusively introduced by fuji corporation, which does not use a conventional square diode but uses an octagonal diode, pixels are arranged in a honeycomb form, and the area of a unit pixel is larger than that of the conventional CCD. As a result of arranging the pixels by rotating them by 45 degrees, an unnecessary space which is not useful for image capturing can be reduced, the efficiency of light concentration is high, and photosensitivity, signal-to-noise ratio, and dynamic range are improved after the efficiency is increased. The SUPERCCD is more compact in arrangement structure than the common CCD, and the utilization rate of the pixels is higher, namely under the same size, the light absorption degree of the light sensing diode of the SUPERCCD is higher, so that the light sensitivity, the signal-to-noise ratio and the dynamic range are improved.
The existing SMT chip mounter mostly adopts a photosensitive Sensor camera to observe a suction nozzle of the chip mounter, so that a user can conveniently confirm the working condition of each suction head, and the phenomenon that the production efficiency is influenced due to the fact that a single suction head breaks down is avoided. Present chip mounter is mostly the chip mounter of many suction heads, and sensitization Sensor shoots the angle less, for guaranteeing to shoot the effect, the camera adopts one-to-one mode to shoot with the suction head more, and present sensitization Sensor adopts the FPGA chip to control more, sensitization Sensor of an FPGA chip control, the cost is higher, and the photo of shooing has the time difference, probably need repeatedly to shoot in order to guarantee to shoot the effect, furthermore, present sensitization Sensor is bulky, the installation is used comparatively inconveniently, in addition, present SMT chip mounter shoots through computer control sensitization Sensor more, because the scheduling problem in the aspect of computer program operation, probably unable timely control sensitization Sensor shoots, be unfavorable for observing the instantaneous behavior of product.
