The device for detecting abnormal appearance of a concentrated water separator according to claim 4, characterized in that: The detection host (41) is equipped with image processing software, image analysis software and control software, the touch panel (44) is equipped with a display screen and control buttons, and the alarm unit (5) is any one of an alarm light, an audible and visual alarm device or a buzzer alarm.

6. The device for detecting abnormal appearance of a concentrated water separator according to claim 4, characterized in that: A deionizing air bar (6) is also installed on the back of the housing (11). The deionizing air bar (6) is located on the outer side of the housing (11) above the discharge hole (15). A product tray (7) is also provided on the back of the housing (11). The product tray (7) is located at the outlet of the discharge hole (15) and corresponds to the deionizing air bar (6). The deionizing air bar (6) is electrically connected to the detection unit (4).

7. The detection method for a concentrated water separator using the detection device according to any one of claims 1 to 6, characterized in that, The detection method includes the following steps: S1: First, close the door (12) of the detection box (1) to reduce the influence of external light sources on the industrial camera (3); S2: The light source (2) and industrial camera (3) are activated by the detection unit (4). The standard concentrate separator product is first input from the feed hole (14) in the detection box (1). The light source (2) provides illumination to the input concentrate separator product. Under the illumination, the industrial camera (3) continuously captures multiple frames of images of the concentrate separator product and transmits the captured images to the detection unit (4) to obtain a standard concentrate separator image. S3: Input the concentrated water separator product to be tested from the feed hole (14) in the test box (1), use the light source (2) to provide illumination to the input concentrated water separator product, and use an industrial camera (3) to continuously capture multiple frames of images of the concentrated water separator product under the illumination, and transmit the captured images to the test unit (4) to obtain the concentrated water separator image to be tested. S4: The detection unit (4) compares and analyzes the image of the concentrated mesh to be tested obtained in step S3 with the standard concentrated mesh image obtained in step S2. When the comparison difference of one of the multiple images of the concentrated mesh to be tested is less than the preset threshold, the corresponding concentrated mesh to be tested is judged to be a defective concentrated mesh, that is, an unqualified concentrated mesh, and an alarm is triggered by the alarm unit (5); otherwise, the corresponding concentrated mesh to be tested is judged to be a defect-free concentrated mesh, that is, a qualified concentrated mesh. At the same time, the normal and abnormal concentrated mesh product data and images are recorded, and the concentrated mesh detection results are generated based on the judgment and identification data and images.

8. The detection method according to claim 7, characterized in that: The detection method also includes a step to eliminate static electricity in the concentrated water separator product. Specifically, when the detected concentrated water separator is a defect-free concentrated water separator, the deionizing air bar (6) is activated through the detection unit (4). The deionizing air bar (6) generates a large number of air masses with positive and negative charges to neutralize the charge on the qualified concentrated water separator product output from the discharge hole (15) so as to achieve the purpose of eliminating static electricity. After eliminating the static electricity of the concentrated water separator, the finished concentrated water separator product is obtained.

9. The detection method according to claim 7, characterized in that: When the light source (2) provides illumination in steps S2 and S3, the light source controller (43) in the detection unit (4) controls the upper light source (21) and the lower light source (22) set in the detection box (1) to be turned on alternately. That is, when the upper light source (21) is turned on, the lower light source (22) is turned off, and when the lower light source (22) is turned on, the upper light source (21) is turned off. The upper light source (21) and the lower light source (22) provide illumination for the industrial camera (3) to continuously capture images.

10. The detection method according to claim 7, characterized in that: In the comparison and analysis process in step S4, the detection host (41) in the detection unit (4) compares the image obtained from the standard concentrate screen product with the image obtained from the concentrate screen product to be tested. The similarity is compared according to the image analysis software configured in the detection host (41), and the threshold is determined by the similarity. If the similarity is above 95%, the concentrate screen product to be tested is judged to be a defect-free product, i.e. a qualified product; otherwise, the corresponding concentrate screen product to be tested is judged to be a defective product, i.e. an unqualified product.
