Description
技术领域technical field
本发明大致涉及一种用于快速检测电热膜红外性能的方法及装置，属于电热膜的工程制造领域。The invention generally relates to a method and a device for rapidly detecting the infrared performance of an electrothermal film, and belongs to the field of engineering manufacturing of the electrothermal film.
背景技术Background technique
目前由于石墨烯穿戴类产品，类似石墨烯加热护膝、加热护腰及护颈类等发热类产品在相关行业，市场上有着良好的发展前景，而检测此类产品质量的高低，其中很关键的一个参考因素即红外发热性能，发热面积越大，发热越均匀，该产品性能质量越高。而工厂如何快速准确的检测其发热红外性能，这需要相应的设施，红外热像仪主要是检测电热膜的发热情况，所以在制造工艺中需要配备专门的红外测量仪器以及配套设备对电热膜进行批量性的检验，电热膜的红外性能对电热膜涉及到的产品性能包括使用寿命和使用稳定性是一项重要的衡量指标。现有的红外测量手段和装置不足之处在于，无法对电热膜实现快速高效的批量性检测，每次红外测量只能人为测量单片电热膜，测量手段单一低效，无法实现红外数据的采集、统计和分析，且每次测量由于红外热像仪的距离，稳定性不一致，一定程度上导致测量结果不准确，从而容易对电热膜性能指标作出错误判断，这些问题都是本发明所要解决的问题。At present, due to graphene wearable products, heating products such as graphene heating knee pads, heating waist pads and neck pads have good development prospects in the market in related industries, and testing the quality of such products is critical. A reference factor is the infrared heating performance. The larger the heating area, the more uniform the heating, and the higher the performance and quality of the product. How to quickly and accurately detect the heating infrared performance of the factory requires corresponding facilities. The infrared thermal imager mainly detects the heating of the electric heating film. Therefore, special infrared measuring instruments and supporting equipment are required in the manufacturing process to carry out the electric heating film. Batch inspection, the infrared performance of the electric heating film is an important measure of the product performance involved in the electric heating film, including service life and use stability. The disadvantage of the existing infrared measurement methods and devices is that they cannot achieve fast and efficient batch detection of the electric heating film. Each infrared measurement can only manually measure a single piece of electric heating film. The measurement method is single and inefficient, and the collection of infrared data cannot be realized. , statistics and analysis, and each measurement due to the distance and stability of the infrared thermal imager is inconsistent, resulting in inaccurate measurement results to a certain extent, so that it is easy to make wrong judgments on the performance indicators of the electrothermal film. These problems are all to be solved by the present invention. question.
目前工厂使用的红外测量手段常规分以下两种：At present, the infrared measurement methods used in factories are conventionally divided into the following two types:
第一种：人为测量，使用高精度的FLUCK TI200红外热像仪，或者普通的手持式热像仪，将一片电热膜平整的放置于台面，连接直接可调电源，通电后，手持热像仪对准电热膜，调整颜色及距离，查看红外发热情况，结束后，断开电源，连接下一片电热膜。此方法较为传统，缺点较多。1、电热膜置于台面，发热时底部热量无法及时散出，积累在电热膜上，导致发热温度数据不准确，影响判断；2、人为手持热像仪无法保证每次测量距离一致，测量中双手的抖动会造成对红外发热面积、均匀性的不直观感受；3、检测效率低下，平均每片电热膜测量时间在25s；4、由于是人为判断，没有标准用于判断产品合格与否，导致不同的检验员检测结果有较大出入。The first type: manual measurement, use a high-precision FLUCK TI200 infrared thermal imager, or an ordinary handheld thermal imager, place a piece of electric heating film flat on the table, connect to a direct adjustable power supply, and after power on, hold the thermal imager Aim at the electric heating film, adjust the color and distance, check the infrared heating situation, after the end, disconnect the power supply and connect the next electric heating film. This method is more traditional and has many disadvantages. 1. The electric heating film is placed on the table, and the heat at the bottom cannot be dissipated in time when it is heated, and it accumulates on the electric heating film, resulting in inaccurate heating temperature data and affecting judgment; The shaking of the hands will cause an unintuitive feeling of the infrared heating area and uniformity; 3. The detection efficiency is low, and the average measurement time of each electric heating film is 25s; 4. Since it is a human judgment, there is no standard for judging whether the product is qualified or not. This leads to large discrepancies in the test results of different inspectors.
第二种：采用简易的机械平台配合电热膜的测量治具来实现每片的快速测量，将电热膜固定在热像仪的正下方，处于通电状态的弹簧铜针在气压装置的作用下接触电热膜的电极，使用热像仪检测电热膜的红外性能。测量结束将弹簧铜针远离电热膜，再接着进行下一张电热膜的检测，保持热像仪的镜头与电热膜的距离一致。相比于第一种方法，红外测量的准确度有所提升，此方法的缺点也显而易见：1、由于是人为判断，没有标准用于判断产品的合格与否，导致不同检验员检测结果有较大出入；2、无法快速的测量大批量的电热膜，每次更换电热膜都需要消耗时间，经实际测试，每片电热膜的测量时间为15s，1小时员工不间断测量仅能测900片，实际测量中，仅能测700片；3、由于电热膜位置与弹簧铜针距离较近，而弹簧铜针处于通电状态，检验员具有误接触到带电的弹簧铜针的风险。以上缺点是本方法在应用中无法有效克服的困难。The second: use a simple mechanical platform with the measuring jig of the electric heating film to realize the rapid measurement of each piece, fix the electric heating film directly under the thermal imager, and the spring copper needle in the energized state contacts under the action of the air pressure device Electrodes of the electric heating film, use a thermal imager to detect the infrared performance of the electric heating film. At the end of the measurement, keep the spring copper needle away from the electric heating film, and then proceed to the detection of the next electric heating film, keeping the same distance between the lens of the thermal imager and the electric heating film. Compared with the first method, the accuracy of infrared measurement has been improved, and the shortcomings of this method are also obvious: 1. Since it is a human judgment, there is no standard for judging whether the product is qualified or not, resulting in different test results of different inspectors. Large discrepancies; 2. It is impossible to quickly measure a large number of electric heating films, and it takes time to replace the electric heating film. After actual testing, the measurement time of each electric heating film is 15s, and the staff can only measure 900 pieces of uninterrupted measurement in 1 hour. , in the actual measurement, only 700 pieces can be measured; 3. Since the position of the electric heating film is relatively close to the spring copper needle, and the spring copper needle is in the energized state, the inspector has the risk of mistakenly touching the charged spring copper needle. The above shortcomings are difficulties that the method cannot effectively overcome in application.
针对于第一种和第二种红外检测方法的缺点，本发明提供的装置和方法采用高精度手持式或固定式热像仪，配合图像分析软件，同时采用传输带的形式传输电热膜，能够快速检测电热膜的红外性能，并且提升了检测结果的准确度，能够有效解决实际工作中员工触电的风险，保证工厂能够快速检测大批量的电热膜。In view of the shortcomings of the first and second infrared detection methods, the device and method provided by the present invention use a high-precision hand-held or fixed thermal imager, cooperate with image analysis software, and transmit the electric heating film in the form of a conveyor belt, which can Quickly detect the infrared performance of the electric heating film, and improve the accuracy of the detection results, which can effectively solve the risk of electric shock for employees in actual work, and ensure that the factory can quickly detect a large number of electric heating films.
