Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of absorbance detection, and in particular relates to a detection method for detecting contamination points on the inner wall of a test bottle. Background Technology
[0002] Absorbance refers to the ratio of the intensity of incident light before it passes through a solution or substance to the intensity of transmitted light after passing through the solution or substance. In laboratories, absorbance testing of river water samples is commonly used to determine the degree of pollution in the water.
[0003] To ensure the accuracy of test results, researchers typically select the optimal testing area on the test bottle before cleaning the outer wall of that area to prevent contaminants from affecting the results. However, the inner wall of the bottle is also easily contaminated, thus affecting the final test results. Currently, existing experiments cannot detect whether there are contaminants on the inner wall of the test bottle. Therefore, even with repeated use of the test bottle, the final test results remain inaccurate. Summary of the Invention
[0004] Therefore, it is necessary to provide a detection method for detecting contamination points on the inner wall of test bottles, addressing the technical problems existing in the prior art.

[0006] A test bottle is provided, wherein the test bottle has a detection site;
[0007] The test bottle is held by a robotic arm and lowered into the receiving cavity so that the rays generated by the absorbance meter can be aligned with the detection area of the test bottle.
[0008] The absorbance of the test bottle, which is rotated 360° under the drive of the robotic arm, is measured using the absorbance detector, and the measured data is recorded. Each measured data corresponds to a measured point on the test bottle.
[0009] All recorded test data are compared. If abnormal test data is found, it is determined that the test point corresponding to the abnormal test data on the test bottle has been contaminated.
[0010] In one embodiment, the detection method further includes the following steps:
[0011] The test bottle is rotated within the accommodating cavity by a robotic arm, so that the rays generated by the absorbance detector are aligned with the contaminated detection points on the test bottle.
[0012] The test bottle is rotated 180° again by a robotic arm. During this process, the test bottle is offset relative to the accommodating cavity, and the absorbance detector is used to detect the test bottle after the 180° rotation to obtain the detection data.
[0013] The abnormal detection data is compared with the detection data obtained after rotating the test bottle 180°, and the location of the contaminated detection point on the test bottle is determined based on the comparison result.
[0014] In one embodiment, the robotic arm can abut against the semicircular surface of the semicircular arc and rotate the test bottle 180° so that the test bottle can shift its position relative to the accommodating cavity under the action of the robotic arm.
[0015] The semi-circular arc stop is eccentrically positioned relative to the test bottle.
[0016] In one embodiment, the robotic arm is rotatably connected to a roller, and the robotic arm can abut against the semicircular surface of the semicircular arc stop via the roller.
[0017] In one embodiment, multiple vertical marking lines are marked side by side on the outer wall of the test bottle, and the spacing between two adjacent vertical marking lines is not equal; wherein, each vertical marking line is set to be opaque and can be detected and confirmed by the absorbance detector in the test bottle.
[0018] The detection area of the test bottle is located within the area where the multiple vertical marking lines are located.
[0019] In one embodiment, each of the vertical marking lines is of equal length.
[0020] In one embodiment, the outer wall of the test bottle is also marked with multiple horizontal marking lines, and the spacing between two adjacent horizontal marking lines is also unequal. Each horizontal marking line is set to be opaque and can be detected and confirmed by the absorbance detector in the test bottle.
[0021] Multiple horizontal marking lines are positioned below the detection area.
[0022] In one embodiment, the accommodating cavity is provided with a cleaning cotton, which can clean the outer wall of the test bottle placed into the accommodating cavity, so as to keep the outer wall of the test bottle placed into the accommodating cavity aligned with the detection part of the absorbance detector clean.
[0023] In one embodiment, the test bottle contains distilled water, and the level of the distilled water is set higher than the detection site.
[0024] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:
[0025] The present invention provides a method for detecting contamination points on the inner wall of test bottles. This method utilizes the abnormality of the data obtained from the operation of an absorbance analyzer to determine whether the inner wall of the test bottle is contaminated, thereby enabling the detection of contamination points on the inner wall of the test bottle. No additional experimental setup is required in this process; the detection can be completed using an existing absorbance analyzer for detecting the absorbance of sampled river water and a robotic arm. This reduces costs and facilitates subsequent cleaning of the inner wall of the test bottle. Attached Figure Description

Detailed Implementation
[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0033] The method for detecting contamination points on the inner wall of a test bottle, which is claimed in this application, can detect contamination points on the inner wall of the test bottle 200 using an existing absorbance meter (not shown) and a robotic arm 10 that grips the test bottle 200.
[0034] like Figs. 1 to 3 As shown, a detection method provided in one embodiment of this application includes the following steps:
[0035] Test bottle 200 is provided, wherein test bottle 200 has a detection site (not shown in the figure);
[0036] The robotic arm 10 holds the test bottle 200 and drives it to be lowered into the accommodating cavity 21 so that the rays 22 generated by the absorbance detector can be aligned with the detection area of the test bottle 200.
[0037] The absorbance of the test bottle 200, which is rotated 360° under the drive of the robot arm 10, is measured using an absorbance meter, and the measured data is recorded. Each measured data corresponds to a measured point on the test bottle 200.
[0038] All recorded test data are compared. If abnormal test data is found, it is determined that the test point corresponding to the abnormal test data on the test bottle 200 has been contaminated.
[0039] It should be noted that the detection site of the test bottle 200 is the optimal detection site when the test bottle 200 is filled with sampled river water; however, when the detection data obtained by the absorbance analyzer differs significantly from other detection data, it means that the detection data is abnormal. When the inner wall of the test bottle 200 is contaminated, this will cause the detection data of the absorbance analyzer to be abnormal.
[0040] It is understood that the detection method for detecting contamination points on the inner wall of the test bottle in this application uses the abnormality of the detection data obtained by the absorbance detector to determine whether the inner wall of the test bottle 200 is contaminated, thereby realizing the detection of contamination points on the inner wall of the test bottle 200. In this process, no other experimental setup is added. The detection can be completed using the existing absorbance detector for detecting the absorbance of sampled river water and the robotic arm 10. This reduces costs and facilitates the subsequent cleaning of the inner wall of the test bottle 200.
[0041] It should be noted that when the absorbance analyzer measures the inner wall of the test bottle 200, a certain number of points can be selected on the detection area of the test bottle 200, such as 180 points, 300 points, 400 points, etc., and the absorbance analyzer can measure the absorbance of the selected points on the test bottle 200 during operation. Specifically, the robotic arm 10 can grasp the cap 210 of the test bottle 200 and can move and rotate the test bottle 200 360°. Of course, the specific structure and working principle of the robotic arm 10 and the absorbance analyzer can adopt conventional forms currently available on the market, and will not be elaborated here.
[0042] In one embodiment, the receiving cavity 21 is provided with a cleaning cotton 211, which can clean the outer wall of the test bottle 200 placed into the receiving cavity 21, so as to keep the outer wall of the test bottle 200 aligned with the detection part of the absorbance detector ray 22 clean. This arrangement avoids the contamination of the outer wall of the test bottle 200 affecting the determination of the contamination of the inner wall of the test bottle 200.
[0043] When the robotic arm 10 rotates the test bottle 200 360° in the accommodating cavity 21, the absorbance detector generates rays that irradiate two symmetrical detection points along the center line of the test bottle 200. If the detection data is abnormal, it means that both detection points corresponding to the rays 22 may be contaminated.
[0044] Therefore, the detection method of this application also includes the following steps:
[0045] The robotic arm 10 drives the test bottle 200 to rotate within the accommodating cavity 21 so that the rays generated by the absorbance detector are aligned with the contaminated detection points on the test bottle 200.
[0046] The robotic arm 10 rotates the test bottle 200 by 180° again. During this process, the test bottle 200 shifts its position relative to the accommodating cavity 21, and the absorbance detector is used to detect the test bottle after rotating 180° to obtain the detection data.
[0047] The abnormal detection data is compared with the detection data obtained after rotating the test bottle 200 by 180°. Based on the comparison results, the location of the contaminated detection point on the test bottle 200 is determined on the detection site.
[0048] It should be noted that while the test bottle 200 rotates 180° within the accommodating cavity 21, it also shifts relative to the accommodating cavity 21. If the absorbance detector returns to normal after rotating the test bottle 200 by 180°, it means that the test point on the test bottle 200 that was directly irradiated by the ray 22 is contaminated. If the absorbance detector maintains the original value after rotating the test bottle 200 by 180°, it means that the test point on the test bottle 200 that was irradiated by the ray 22 and passed through the test bottle 200 is contaminated.
[0049] Correspondingly, the robotic arm 10 can abut against the semicircular surface 31 of the semicircular arc stop 30 and drive the test bottle 200 to rotate 180°, so that the test bottle 200 can shift its position relative to the accommodating cavity 21 under the drive of the robotic arm 10.
[0050] Among them, the semi-circular arc stop 30 is set off-center relative to the test bottle 200.
[0051] It should be noted that since the robotic arm 10 needs to rotate the test bottle 200 during operation, the robotic arm 10 usually includes a bearing (not shown in the figure). For those skilled in the art, the bearing has a clearance variation. Therefore, when the robotic arm 10 is against the semi-circular arc stop 30 set eccentrically relative to the test bottle 200 and rotates 180°, it can drive the test bottle 200 to make a slight displacement relative to the accommodating cavity 21. Since the area corresponding to the detection point on the test bottle 200 is small, the slight displacement of the test bottle 200 relative to the accommodating cavity 21 is sufficient to meet the usage requirements.
[0052] Among them, the robotic arm 10 is rotatably connected to a roller 11, and the robotic arm 10 can abut against the semi-circular surface 31 of the semi-circular arc stop 30 through the roller 11.
[0053] In one embodiment, multiple vertical marking lines 201 are marked side-by-side on the outer wall of the test bottle 200, with unequal spacing between adjacent vertical marking lines 201. Each vertical marking line 201 is set to be opaque and can be detected and its position within the test bottle 200 by an absorbance analyzer. The detection area of the test bottle 200 is located within the area containing the multiple vertical marking lines 201. This arrangement ensures that the detected point falls within the corresponding two vertical marking lines 201, facilitating subsequent cleaning of the test bottle 200 and thus simplifying the cleaning of contaminants from the inner wall of the test bottle 200.
[0054] It should be noted that the location of the detection point in the detection area is determined by using unequal spacing between two adjacent vertical marking lines 201. In this way, the absorbance meter can determine the contaminated detection point on the inner wall of the test bottle 200 by detecting the absorbance of the test bottle 200, which has the effect of reducing costs.
[0055] Each vertical marker line 201 has the same length.
[0056] Specifically, the multiple vertical marking lines 201 on the test bottle 200 of this application can cover the semi-circular arc position of the outer wall of the test bottle 200. Thus, when the absorbance detector performs absorbance testing on the test bottle 200 rotated 180°, if any abnormality occurs in the test data, the abnormal point will fall between two of the vertical marking lines 201 on the test bottle 200. At this time, it is impossible to determine whether the contaminated point on the inner wall of the test bottle 200 is specifically located between the corresponding two vertical marking lines 201, or at a position opposite to the two vertical marking lines 201 on the test bottle 200. Since the test bottle 200 will inevitably be pushed and eccentrically displaced by the semi-circular arc stop 30 during its 360° rotation, the machine... When the robotic arm 10 rotates the test bottle 200 180°, the position of the abnormal data point in the detection data obtained is different from the position of the abnormal data point in the corresponding detection data obtained when the test bottle was rotated 180°. This indicates that the contaminated point of the test bottle 200 is located relative to the two vertical marking lines 201 on the test bottle 200. Conversely, if the position is different, it is located between the two vertical marking lines 201. In this way, the contaminated points on the inner wall of the test bottle 200 can be accurately detected. When cleaning the test bottle 200 later, the detected area can be cleaned thoroughly, and the contaminated points on the inner wall of the test bottle 200 can be cleaned completely. It should be noted that the above detection method allows for accurate detection of contamination points on the inner wall of the test bottle 200 by rotating it 360°. This ensures accurate cleaning of the contamination points on the inner wall of the test bottle 200. Without accurate identification of the contamination points on the inner wall of the test bottle 200, conventional cleaning methods cannot effectively clean them. This will affect the detection results when using the test bottle to test the river water for absorbance analysis of contamination levels.
[0057] It should be noted that the optimal detection location differs for different test bottles 200. Therefore, when detecting contaminants on the inner wall of different test bottles 200, the test bottles 200 need to be identified first to facilitate subsequent control of the depth to which the test bottles 200, held by the robotic arm 10, are lowered into the receiving cavity 21. Of course, the specific optimal detection location on the test bottle 200 can be determined by detecting contaminants at different heights when both the inner and outer walls of the test bottle 200 are uncontaminated; this will not be elaborated upon here.
[0058] To this end, the outer wall of the test bottle 200 of this application is also marked with multiple horizontal marking lines 202. The spacing between adjacent horizontal marking lines 202 is also unequal. Each horizontal marking line 202 is set to be opaque and can be detected and confirmed by an absorbance meter to determine its position in the test bottle 200. The multiple horizontal marking lines 202 are located below the detection area. During the process of the robotic arm 10 lowering the test bottle 200 into the receiving cavity 21, the multiple horizontal marking lines 202 are first detected by the absorbance meter to determine the information of the test bottle 200, thereby ensuring the depth of the test bottle 200 in the receiving cavity 21 and ensuring that the detection area of the test bottle 200 is aligned with the upper ray 22 of the absorbance meter.
[0059] Similarly, by using unequal spacing between adjacent horizontal marking lines 202, the identity of the test bottle 200 is determined. This ensures that when the robotic arm 10 lowers the test bottle 200 into the receiving cavity 21, the detection area of the test bottle 200 is aligned with the X-ray 22 on the absorbance meter. In this way, the absorbance meter can authenticate the test bottle 200 simply by measuring its absorbance, thus reducing costs.
[0060] Additionally, it should be noted that the test bottle 200 is filled with distilled water, and the level of the distilled water is set higher than the detection area. This allows for subsequent use of absorbance to detect contamination points on the inner wall of the test bottle 200.
[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0062] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
