Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to a device for detecting the surface uniformity of NC films. Background Technology

[0002] NC membranes (nitrocellulose membranes) have a wide range of applications in many fields, such as in biological detection (e.g., immunochromatographic detection), where they serve as important solid-phase carriers.

[0003] During the production process, NC membranes may exhibit inconsistent surface uniformity. This non-uniformity can be caused by various factors, such as uneven solution coating during the production process and localized differences during the drying process. Traditional water run-through testing methods involve injecting an aqueous solution containing colored food coloring into the lower tank. Membranes from different batches are marked every 1 cm (total length greater than 4 cm) and placed on an inclined support, with the lower end of the membrane submerged in the solution tank. Liquid aspiration begins, and timing is recorded, recording the passage time at each mark and comparing it with a control group. During plate running, it is observed whether the solution is drawn upwards in a horizontal line, and whether there are any abnormal phenomena such as wavy tilting or enveloping wetting.

[0004] In addition, microstructure inspection, which involves observing the surface microstructure of the NC membrane using SEM to determine the membrane's uniformity, requires complex equipment or is time-consuming, making it unsuitable for rapid testing on the production line. Utility Model Content

[0005] The purpose of this invention is to provide an NC film surface uniformity detection device to solve the problem of difficulty in rapid detection on the production line.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is an NC film surface uniformity detection device, including a housing assembly, which includes a side plate and a top plate;

[0008] A top plate is installed at the top of each of the two side plates;

[0009] A conveyor frame is installed between the two side plates, the conveyor frame is inclined, and a lighting assembly is provided above the conveyor frame, the lighting assembly is installed on the top plate;

[0010] The NC membrane moves to one side via the conveyor frame;

[0011] By illuminating the inclined conveying NC membrane with an illumination component, the illumination area is increased. The strong light shining on the surface of the NC membrane makes it easier to observe whether the NC membrane is uniform, thereby realizing the detection of the surface uniformity of the NC membrane.

[0012] Furthermore, the conveyor frame includes connecting rods and conveyor rollers;

[0013] Two conveying rollers are installed between the two connecting rods, and the ends of the conveying rollers are installed in pin holes provided at the ends of the connecting rods.

[0014] Furthermore, two limiting posts are provided on the outer surface of the connecting rod;

[0015] The two limiting posts are respectively installed in the pin hole and the arc groove on the side plate. The limiting post slides in the arc groove. The limiting post connected to the pin hole extends out of the pin hole and is fitted with a retaining ring. The limiting post connected to the arc groove has an external thread and is installed in conjunction with a tightening nut. By tightening the tightening nut, the outer side of the connecting rod is pressed against the inner side of the side plate. The friction force is used to fix the position of the connecting rod, which makes it easy to adjust the observation angle.

[0016] Furthermore, a waist-shaped hole is provided at the bottom of the side plate, and a tensioning assembly is installed between the two side plates, with the end of the tensioning assembly installed in the waist-shaped hole.

[0017] The tensioning assembly includes a tensioning roller, the end of which extends outward through a corresponding oblong hole, and a pull rod is sleeved on the end of the oblong hole. One end of the pull rod is mounted on a stand, and a spring and a limiting ring are mounted on the end of the stand.

[0018] When the NC membrane relaxes, the tension roller, under the action of the spring, drives the pull rod and the tension roller away from the lower end of the conveyor frame, thereby tightening the NC membrane.

[0019] The support is fixed to the outer side of the side plate.

[0020] Furthermore, the lighting assembly includes a U-shaped base;

[0021] The U-shaped base is equipped with a lamp body, which includes a housing and a lamp tube. Two lamp tube connection sockets are installed on the inner wall of the housing, and a lamp tube is inserted between the two lamp tube connection sockets.

[0022] The outer sides of both ends of the shell are provided with protruding posts, which are installed in the round holes provided at both ends of 501. After installation, the shell can rotate around the protruding posts.

[0023] A stud is installed at the top of the U-shaped seat. The stud is fitted into the mounting hole in the top plate, and a nut is fitted onto the stud. The nut is located above the top plate.

[0024] The inner wall of the mounting hole is provided with a limiting protrusion, which cooperates with the groove provided on the outside of the stud to prevent the stud from rotating. The height of the U-shaped seat can be adjusted by rotating the nut.

[0025] The U-shaped base has limiting holes on both sides, and the end of the lamp body has protrusions that cooperate with the limiting holes. At the same time, a handle is installed on one side of the lamp body.

[0026] Pulling the handle rotates the lamp body housing, and the protrusion engages with the next limiting hole to achieve a limiting position, thus fixing the lamp body position after rotation.

[0027] This utility model has the following beneficial effects:

[0028] This invention uses an illumination component to irradiate the inclined conveying NC membrane, increasing the irradiation area. By irradiating the surface of the NC membrane with strong light, it is easier to observe whether the NC membrane is uniform, thereby realizing the detection of the surface uniformity of the NC membrane.

[0029] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The strong light shines on the surface of the NC membrane (6), making it easier to observe whether the NC membrane (6) is uniform, thereby realizing the detection of the surface uniformity of the NC membrane.

[0045] The conveyor frame (3) includes a connecting rod (301) and a conveyor roller (302);
