Description

.M289861 IV. Creation Description (1) [New Technology Field] This creation is about a high-depth-field coaxial reflection type detector detector's photoelectric module structure, especially a high depth of field, high stability, and practical value. Easy-to-assemble optoelectronic module structure, can be used in printing industry and packaging industry to print marks and position detection, for the purpose of the machine relative to the need for positioning control, by maintaining the total length of the original optoelectronic module, The position between the beam splitter and the light receiving unit, the design of a focusing lens with a short focal length is added, 'the light emitted from the light source can be transmitted and received by the double lens through the transmission and the anti-1* function of the beam splitter. The optical signal generated by the reflected light receives the light receiving unit focused on the rear end of the casing, thereby improving the depth of field and increasing the stability of the color mark detection for the detection function of the more efficient printed mark position. [Prior Art] The conventional coaxial reflection type dual-source mark detector (as shown in the first figure) has long been used in the printing industry and the packaging industry because it has a large lens and all the light is emitted and received. The process is completed by the S lens, so that it has stable detection performance on the surface of the high-reaction material compared with the biaxial mark detection. Door ^ 曰然, the coaxial reflection type dual-source mark detector y formed by this structure belongs to a passive passive mode, because in general, the detection object such as G: paper swaying up and down during operation is very easy to receive Signal size will be produced

Page 5 M289861 IV. The change in the description of the creation (2), although there is a stability between the signs compared to the mark with a small contrast detection, if the improved signal size variation can be used for the benefit. Moreover, the second illuminating source (such as the first being reflected by the beam splitter to produce the same quality will also produce regrets. Therefore, how to solve such a low depth of field of the β-output, verification is a problem to be solved today. New content] There is no problem with large contrast detection, but 'the above-mentioned sway will affect the detection and reduce the above-mentioned detection performance improvement of the detector due to the up and down sloshing. After the two spots are bothered, the inconvenience caused by the lack of stability of the coaxial reflection type dual light source for the detection configuration is inconvenient. In view of the shortcomings of the above-mentioned technique, the module structure is easy and convenient, but the regret is deep and realistic. The distance focusing mirror can achieve the high efficiency of the original element, and the overall efficiency of the device can be effectively avoided. The convex lens has scattered the depth of field of the two, the stabilizer assembly type is high, and the above effect is reduced in the limited control. The need for transportation, convenient and convenient, resulting in the deep coaxial standard of the examiner's standard space with a true optical letter to increase the color and real simplicity, the lack of reflection The detection distance and the short-numbered color-coded process type are the shortcomings of the detection. The depth of the device is easy to install and insert, and the new photoelectric model that is focused on the light soul is quickly and can be detected. It is true that the short-focusing and convex-receiving reception of the conventional photoelectric device is simplified, and the structure is established.
