At present, the waterstop products mainly include cross type, T-shape, slope type, inner and outer corner type, etc. The most commonly used waterstop belt cross-section shape in engineering buildings is 250 mm in total width and 38 mm in outer diameter of the ring. The inner diameter is 19 mm, the annular wall thickness is 9.5 mm, the wings are 106 mm wide, the wing is 10 mm thick, and the side column diameter is 25 mm. The width dimension of the waterstop is also an important indicator, so it is necessary to more accurately detect the total width of the cross-sectional shape of the waterstop in production. This paper mainly introduces the development and application of the water stop belt online width gauge. 1, the principle of measurement An LED point light source is disposed in the two emitting lenses, and the light emitted by the point source is converted into a parallel beam by the lens and directed to the two receiving lenses. The parallel beam is imaged on the photoelectric conversion element CCD chip by receiving the lens in the lens (note: one emitting lens and one receiving lens form a group of photoelectric probes). When the object to be measured passes through the field of view composed of two parallel beams, a virtual shadow appears on the image of the photoelectric conversion element, and the widths thereof are L1 and L2, respectively. After the electrical signal processing and calculation of the photoelectric conversion element, the dimensions B1 and B2 corresponding to L1 and L2 can be obtained, and B1 plus B2 plus the clear spacing C between the two lenses can be used to obtain the width of the measured object. Size A. In practical applications, the net spacing C of the probe is a dimension calibrated with a fixed length standard rule. When the distance between the probes is changed, the width change of the gauge can be measured. 2, a variety of specifications sealing width detecting The water stop tape online width gauge is manufactured by using a double-barrel probe with a pitch tube. The distance between the two sets of probes can be adjusted. Therefore, the width of the water stop tape of various specifications can be detected online. Dimensions, when changing specifications, adjust the probe spacing, the probe spacing can be automatically adjusted by inputting commands. After adjustment, high-precision waterstop width measurement can be achieved by standard gauge calibration. The water stop belt online width gauge is installed on the production line of the waterstop for dynamic online detection, and the high efficiency detection is performed at a speed of measuring one data every 2ms, and the measurement result is fed back to the display system in real time, and the display frequency is 2~3Hz, which is convenient. The human eye observes, at the same time, it has the function of over-acoustic sound and light alarm, prompting the abnormal production state in time. 3, industrial computer software display The water stop belt online width gauge can display the various information required by the process by adding the industrial computer system. As shown in the above figure, the model, standard width and upper deviation of the tested waterstop can be displayed in detail on the main interface. Information such as deviations. The measured width value and its deviation value can be displayed in real time, and the production state of the water stop can be seen at a glance. The width fluctuation curve is the time axis unit, which shows in detail whether the water stop belt is out of tolerance at different times. The green line has a real-time width curve. The two red lines are respectively upper and lower limits, which can clearly and intuitively observe the overall production of the water stop tape width gauge, and it is easy to grasp the trend of the width dimension of the water stop tape. The water stop online gauge can store the measurement data on the system hard disk for more than 1 year. You can view the historical data at any time, or export the data. Historical data can be used as a basis for shipment, allowing customers to better understand the width value of the waterstop. The water stop online gauge can perform various functions such as setting product parameters, achieving calibration, setting the upper and lower limits of the tolerance alarm. It has been widely used in the production site of waterstops, and the detection of water belts has brought great convenience. 4, high precision measurement The water stop belt online width gauge is used for high-precision detection of the width of the water stop belt. In order to achieve high-precision measurement, the telecentric parallel light source is used for detection, and the edge measurement method and the intermediate fixed size value method are used for width detection. At the same time, the water stop tape width gauge eliminates the measurement error caused by the water stop belt jitter, and the non-contact measurement method reduces the error caused by the contact deformation. The water stop belt online width gauge uses a variety of techniques and algorithms to increase the accuracy value, and its measurement accuracy can generally reach 0.05mm, and can be made into a more accurate water stop belt online width gauge. Conclusion The water stop belt online width gauge is used in the width dimension detection of the water stop belt. It can perform high-precision width dimension detection on various types of waterstops, and can realize water stop of various widths by adjusting the probe spacing. With the detection of the belt, it is easy to use and easy to operate, and the online detection of the width dimension of the water belt provides great convenience.
