Description

Hydrogel visual identification detection equipment and detection method Technical Field The invention relates to the technical field of hydrogel performance detection, in particular to a hydrogel visual identification detection device and a detection method. Background The swelling property of a hydrogel refers to the property that a hydrogel can absorb a large amount of water in a solution to cause an increase in volume but not dissolve, and in order to detect the swelling property of a hydrogel, it is theoretically possible to detect by observing a change in volume of a recorded hydrogel or by weighing a recorded hydrogel. However, since the hydrogel has extremely high water content and extremely high transparency, the outline is difficult to detect, and it is difficult to visually identify, and it is difficult to accurately divide the edges of the hydrogel, so that it is difficult to detect by directly observing and recording the volume change of the hydrogel. The detection method commonly used at present is to record the volume change of hydrogel indirectly or record the weight change of hydrogel by weighing, such as tea bag method, sieving method, filtering method, sieving method, weighing method, fluorescence method and the like. However, the tea bag method, the screen method and the filtration method can limit the contact of the hydrogel with the test solution, so that the hydrogel cannot fully contact the test solution, and can limit the swelling deformation of the hydrogel, so that the swelling rate of the hydrogel is inaccurate. The weighing method needs to accurately weigh and operate, is easily interfered by external factors, and causes the accuracy of the detection result to be reduced. The fluorescence method is also easily affected by interference of fluorescence signals and background noise, and the accuracy of detection results is reduced. In addition, the methods basically need complex detection equipment or higher technical requirements, are relatively complicated to operate, and the detection result is also easily influenced by experimental conditions, so that the detection efficiency is low and the error of the detection result is larger. Disclosure of Invention In order to overcome the defects of the prior art, the invention aims to provide the hydrogel visual identification detection equipment which can solve the problem that visual detection cannot be performed due to high hydrogel transparency, and can detect the swelling property of the hydrogel by directly observing and recording the volume change of the hydrogel, so that the detection efficiency can be improved, and the accuracy of a detection result can be improved. In order to solve the problems, the technical scheme includes that the hydrogel visual identification detection device comprises a frame, a light source module, a camera module, a mask and an observation box, wherein the light source module, the camera module, the mask and the observation box are connected to the frame, the mask is arranged between the light source module and the camera module, the observation box comprises a detection grid for storing hydrogel and a test solution, the light source module, the mask, the observation box and the camera module are sequentially distributed in the vertical direction during detection, the light source module irradiates towards the mask, and the camera module continuously shoots the hydrogel in the detection grid. Compared with the prior art, the detection device has the beneficial effects that the swelling condition of the hydrogel can be observed and recorded by adopting the mode that the camera module shoots the hydrogel, the detection device is a detection mode for directly and intuitively observing and recording the volume change of the hydrogel, and tools such as a screen or a filter are not needed, so that the contact of the hydrogel with a test solution is not limited, the expansion deformation of the hydrogel is not limited, the detection result is more accurate, the detection efficiency is higher, and the operation is more convenient. When detecting, this check out test set distributes in proper order light source module, the mask, observe the box and make a video recording the module along vertical direction, light source module shines towards the mask direction, make light see through the mask and look into in the box, and utilize the mask to provide sharp contrast color for hydrogel, make the hydrogel can be by visual identification, the problem that can't carry out visual detection because of the hydrogel transparency is high has been solved, make the hydrogel that makes a video recording the module shoot more clear complete, thereby can accurately cut apart the edge profile of hydrogel, in order to observe the swelling condition of recording the hydrogel, the swelling performance of analysis hydrogel better.
