Recently, Beijing Liebang Instrument Technology Co., Ltd. (hereinafter referred to as "the state apparatus") successfully developed a battery height automatic detection system. The system has the advantages of high measurement accuracy, fast detection speed, and the scratch detection problem of manual detection. After simple modification, the system can be widely applied to full-size and accurate measurement of various square lithium battery products, such as mobile phones, MP3s, MP4s, Digital camera battery and so on. The industry generally believe that the system to fill the gaps in the industry, will greatly improve the quality of battery manufacturers related testing efficiency. Will change the status of manual testing Lithium battery height detection, the traditional way is generally manually using calipers to measure, by the edge of the battery welding will reduce the accuracy of manual testing, and manual caliper detection itself, the presence of inaccurate test data, which resulted in the factory The biggest problem - the size of the measured data is not accurate. Factory testing a large number of batteries in the testing process of human involvement in judgments, the detection of errors is difficult to trace the source, the negative impact on product quality immeasurable. Therefore, lithium battery measurement data is not accurate, manual judgment errors, emotional out of control and many other subjective and objective factors, will seriously affect the quality of lithium battery delivery. At present, the lithium battery height measurement in the field of automatic detection is almost a blank, for this imbalance in the market, the State Department of Instrument and Organization Engineers team began testing lithium-ion battery system for research and development. After months of field investigation and program design, "lithium battery height automatic detection system" was available. The system equipment can detect 40 lithium batteries per minute, the test accuracy of 0.02mm, the detection of battery size covering a wide range of width 25 ~ 80mm, thickness 3.0 ~ 15mm, height 30 ~ 100mm. New equipment using laser detection technology The system uses advanced laser testing technology, the choice of two lasers for height measurement, through the relative displacement between the battery and the laser to achieve the battery ends of the contour scan, with the State Instrument independent research and development software to extract the height of the test and analysis software , And calculate the height difference. The system uses non-contact optical measurement, rapid detection of a variety of lithium battery products, height and height difference, and automatic sorting. Manual feeding to the material box for testing, testing the battery is divided into qualified and unqualified products, and its classification output. The device has the automatic detection of data storage capabilities, statistics of each batch of products such as pass rate data, automatically generate reports to facilitate the traceability and control of product quality. According to the introduction of instrumentation engineers from the state, the system equipment testing can be done only by one worker, which can greatly save the labor cost of the user and help the workers tighten their nerves and relieve their breath. At the same time, the detection accuracy and work efficiency of users' products can also be greatly improved. The working mode of "caliper + eyes + hands" no longer meets the requirements of the electronics industry for product testing. Lithium battery height detection equipment has the advantages of simple structure, high reliability and low maintenance cost. After a small amount of modification, the solution can also be applied to full-size testing of various square lithium battery products, such as mobile phones, MP3s, MP4s and digital camera batteries. Professionals believe that the system will greatly improve the quality of related battery manufacturers to detect efficiency, to fill the field of automatic battery height detection of the market gap.
Submersible Mixer
The QJB series submersible mixer is one of the key equipments in the water treatment process. It is mainly used for the purposes of mixing, agitating and making ring flows in the process of municipal and industrial sewage treatment and can also be used as the maintenance equipment for the landscape water environment,through agitation, they can achieve the function of creating water flow,improving the quality of the water body,increasing the oxygen content in water and effectively preventing the sedimentation of the suspended substances. It has the advantages of compact structure, low energy consumption, and easy maintenance. The impeller is precision-cast or stamped, with high precision, high thrust, and streamlined shape, which is simple, beautiful and has anti-winding function. This series of products are suitable for places that require solid-liquid stirring and mixing.
