Description

Technical Field

[0001] This utility model belongs to the field of test strip card assembly and production technology, and in particular relates to an auxiliary tooling for pasting test strip cards. Background Technology

[0002] Colloidal gold test strips are rapid diagnostic tools made using the principle of colloidal gold immunochromatography, commonly used to detect viral antigens. Their working principle utilizes colloidal gold as a colorimetric medium, combining it with the specific antigen-antibody binding reaction in immunology to achieve the detection purpose. Colloidal gold test strips are widely used in disease diagnosis due to their ease of use and rapid result interpretation. A typical colloidal gold test strip includes a sample pad, a gold pad, and an absorbent pad, which are interconnected and adhered to a PVC base plate covered with a nitrocellulose membrane.

[0003] In existing technologies, assembly is completed by manual pasting. However, manual pasting makes it difficult for production workers to maintain a uniform standard, resulting in uneven pasting positions. This can easily lead to deviations in the cut test strip cards, affecting the effectiveness. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an auxiliary tooling for pasting test strips, which ensures the consistency of the pasting position of the sample pad, gold pad and absorbent pad, and improves the pasting efficiency to a certain extent.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a test paper card pasting auxiliary fixture, including a base plate, a fixed baffle, a movable baffle, and an auxiliary pasting mechanism. The upper surface of the base plate is provided with a pasting area for placing adhesive sheets. The fixed baffle and the movable baffle are both arranged along the length of the pasting area, and the fixed baffle and the movable baffle are respectively located on the front and rear sides of the adhesive sheet. The fixed baffle is fixed to the base plate. The movable baffle is provided with an oblong hole. A screw passes through the oblong hole and is threadedly connected to the base plate to fix the movable baffle, thereby facilitating the adjustment of the position of the movable baffle to limit the adhesive sheets with a width of 6cm and 8cm respectively.

[0006] The auxiliary pasting mechanism includes a pressure plate and sliding blocks located on both sides of the pressure plate. The pressure plate can move back and forth along the width of the pasting area. The sliding blocks have mounting cavities, and a connecting rod arranged vertically is installed inside the mounting cavity, with the connecting rod passing through the pressure plate. A compression spring is provided between the pressure plate and the top surface of the mounting cavity, and the compression spring is sleeved on the connecting rod. The base plate has a guide groove, and the sliding block is located between the guide groove and the fixed seat. The fixed seat is fixed to the base plate. The adhesive plate is placed between the fixed baffle and the movable baffle, and then the pressure plate is moved above the nitrocellulose membrane. The pressure plate is pressed down under the action of the spring. At this time, it is necessary to ensure that the two sides of the nitrocellulose membrane are not pressed by the pressure plate. The gold pad is attached to the adhesive plate and the nitrocellulose membrane with the pressure plate close to it. Then, the sample pad is attached to the adhesive plate and the gold pad with the movable baffle close to it. Finally, the absorbent paper is attached to the adhesive plate and the nitrocellulose membrane with the fixed baffle close to it. This ensures the consistency of the pasting position of the sample pad, gold pad, and absorbent pad, and improves the pasting efficiency to a certain extent.

[0007] Furthermore, a nitrocellulose film is attached to the upper surface of the adhesive sheet, and the pressure plate presses against the nitrocellulose film.

[0008] Furthermore, the mounting base is provided with a mounting groove, and a pressure strip is installed inside the mounting groove. A bolt is threadedly connected to the mounting base, the lower end of the bolt is rotatably connected to the pressure strip, and the upper end of the bolt is connected to a knob.

[0009] Furthermore, scale lines are provided on both sides of the mounting area.

[0010] Furthermore, the lower surface of the base plate is provided with mounting holes, and an anti-slip rubber pad is installed inside the mounting holes, with the anti-slip rubber pad protruding from the mounting holes.

[0011] Furthermore, the bottom surface of the anti-slip rubber pad is provided with several raised anti-slip strips.

[0012] Furthermore, the sides of the base plate are chamfered.

[0013] Furthermore, it also includes a push plate, which includes a groove that matches the pressure plate and a pressing portion extending from the groove to both sides.

[0014] Furthermore, the lower surface of the pressing part is provided with a guide surface, and the guide slope gradually slopes upward from the center of the pressing part to the side.

[0015] Furthermore, the bottom surface of the pressing part is provided with a pressing protrusion, the lower surface of the pressing protrusion is arc-shaped, and the pressing protrusion is arranged along the width direction of the mounting area.
