Description

Technical Field

[0001] The utility model belongs to the technical field of colloidal gold film-scribing machines, and particularly relates to a film-scribing and cleaning alternating mechanism of a colloidal gold film-scribing module. Background Art

[0002] Nitrocellulose membrane, also known as NC membrane, is a very important consumable in biological experiments. It is mainly used as a carrier of the C / T line in colloidal gold test paper and is also the site of immune reaction. The process of colloidal gold streaking is to fix the colloidal gold marker on the NC membrane. This step is crucial in colloidal gold immunochromatography testing. Colloidal gold immunochromatography is a rapid in vitro diagnostic method that uses colloidal gold as a marker to form a visible signal on the membrane through the reaction between antibodies and antigens, thereby realizing the detection of specific substances. During the streaking process, the colloidal gold marker is evenly applied to the NC membrane. This step is not only related to the sensitivity and accuracy of the test, but also affects the reliability and repeatability of the test results.

[0003] Conventional membrane equipment only has one set of membrane stripping mechanism. For the joint problem of NC membrane, since membrane stripping is not allowed on the joint, the machine needs to be stopped for manual processing. In addition, the membrane stripping pump needs to clean the nozzle after working for a period of time, which also takes up working time. Therefore, the existing membrane stripping equipment has low working efficiency and the continuity of the membrane stripping operation is not strong, which needs to be improved on this basis.

[0026] like Figure 1-8 The present invention shows a colloidal gold scribing module of the alternating scribing and cleaning mechanism, including a table 1, a vertical mounting panel 2, a conveying table 3, a first scribing mechanism 5, a second scribing mechanism 6, a visual inspection mechanism 7 and a waste marking component 8.

[0027] A vertical mounting panel 2 is fixedly provided on the horizontally arranged table 1, and a conveying platform 3 parallel to the vertical mounting panel 2 is provided on the table in front of the vertical mounting panel 2. The conveying platform 3 carries and conveys the NC film workpiece, and a first film stripping mechanism 5 and a second film stripping mechanism 6 with the same structure are installed side by side on the vertical mounting panel 2; a working liquid adding container 21, two sets of bubble removal machines 22 and a plunger pump mechanism 23 are also provided on the vertical mounting surface 2, and the two sets of bubble removal machines 22 and the plunger pump mechanism 23 are respectively connected to the two film stripping mechanisms, and the working liquid adding container 21 supplies working liquid to the plunger pump mechanism 23, and each set of plunger pump mechanism 23 pumps working liquid to the corresponding first film stripping mechanism 5 or the second film stripping mechanism 6, so that the corresponding film stripping mechanism performs film stripping operation.

[0028] The two film-scraping mechanisms can move up and down just above the conveying platform 3. A movable cleaning tank 33 is provided on the conveying platform 3. The movable cleaning tank 33 cleans the first film-scraping mechanism 5 and the second film-scraping mechanism 6 alternately.

The bottom of the movable cleaning tank 33 is slidably connected to the fixed baffle 31 . The movable cleaning tank 33 can clean the film head 54 .

[0031] The conveying platform 3 is also provided with a plurality of transmission roller assemblies 34, which are spaced apart along the length of the conveying platform. The transmission roller assemblies 34 include a lifting support seat 341 and a driving roller 342. The lifting support seat 341 is mounted on the conveying platform 3, and the driving roller 342 is connected to the lifting support seat 341. The driving roller 342 provides power for the transmission of the NC film workpiece.

[0032] The visual inspection mechanism 7 and waste marking assembly 8 are sequentially arranged behind the conveyor of the two film stripping mechanisms. After the film stripping operation, the NC film workpiece passes under the visual inspection mechanism 7. The visual inspection mechanism 7 detects unqualified film sections, and the waste marking assembly 8 inkjet-marks the unqualified film sections. The visual inspection mechanism 7 includes a housing 71, a camera 72, and a light source 73. The housing 71 is connected to the vertical mounting panel 2 and suspended above the conveyor platform 3. The top of the housing 71 is provided with a vertically downward-facing camera 72. The bottom of the housing 71 is open, and a circle of light sources 73 is provided along the bottom edge of the housing 71. The NC film workpiece is conveyed from under the housing 71, and the camera 72 takes photos of the NC film workpiece for inspection. The waste marking assembly 8 includes a vertical bracket 81, a micrometer slide 82, an inkjet printer 83 and a laser sensor 84. The vertical bracket 81 is fixedly connected to the table 1, and the micrometer slide 82 is vertically slidably connected to the vertical bracket 81. The micrometer slide 82 is connected to the mounting plate, and the inkjet printer 83 and the laser sensor 84 are installed on the mounting plate. The micrometer slide 82 adjusts the coding position of the inkjet printer 83 through the mounting plate, and the laser sensor 84 detects the coding status of the NC film workpiece.

[0033] The working process of the present invention is as follows: the NC film workpiece is conveyed from one end of the conveying platform 3 to the other end, and the transmission roller assembly 34 on the conveying platform 3 provides power for the flow of the NC film workpiece. The joint part of the NC film workpiece is first sensed by the joint detection sensor 4, and the joint detection sensor 4 transmits the signal to the first or second film-scraping mechanism. After the film-scraping mechanism in the working state receives the signal, the corresponding plunger pump stops discharging liquid, and then the horizontal bracket 52 slides upward along the Z-axis linear module 51, lifting the film-dotting head 54 upward and leaving the conveying platform 3. When the joint part passes the film-dotting area, the film-dotting head 54 falls again, and the plunger pump is started to continue the film-scraping work. The first film stripping mechanism 5 and the second film stripping mechanism 6 perform film stripping work alternately, and the movable cleaning tank 33 can be manually slid on the conveying table 3. Therefore, when the first film stripping mechanism 5 is working, the second film stripping mechanism 6 can be cleaned, and when the second film stripping mechanism 6 is working, the first film stripping mechanism 5 can be cleaned, thereby ensuring the continuity of the film stripping work and timely maintenance and cleaning of the film stripping mechanism to avoid blockage and ensure the film stripping quality; after the NC film workpiece is filmed, it passes under the visual inspection mechanism 7, and the camera on the top of the shell 71 takes pictures of the NC film workpiece for inspection. Since the NC film joint part is not film-stripped, according to the results of the camera inspection, the inkjet printer 83 performs coding operation on the joint area and marks it as NG product. At the same time, for the normal film stripping section, if an area with unqualified film stripping is detected, the inkjet printer 83 also performs waste spraying processing. After coding, the NC film workpiece continues to be transported backward, and the laser sensor 84 further detects the waste spraying area to ensure the waste spraying effect and avoid missed spraying or wrong spraying.

[0034] The above descriptions are merely some preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes and substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
