Description

Technical Field

[0001] The present invention relates to the technical field of paper cutting, and specifically to a test strip cutting device and method. Background Art

[0002] Test strips are a type of rapid detection tool designed based on specific biological or chemical principles, and are widely used in medical diagnosis, environmental monitoring, and daily life scenarios. The principle is to pre-place antibodies or antigens labeled with colloidal gold in the test strip. When the sample (blood, urine) contains the target substance, an "antigen-antibody-colloidal gold" complex is formed, which moves along the chromatographic membrane and accumulates and develops color at the test line (T line); When existing test strips are manufactured, multiple groups of antibodies and antigens are uniformly coated on a whole piece of paper, and then sorted out by cutting. However, traditional cutting devices cut the paper by means of a cutting knife, which has a minimum specification requirement. After the test strip is formed, in order to facilitate installation and use, and to reduce costs and protect resources, its width and length are often minimized. The traditional cutting device cannot meet the width requirement, so it can only be cut by a manual cutting knife, with low efficiency. Moreover, the test strip collapses after cutting, making it difficult to sort out later; The manual cutting knife may have problems such as the uneven edge of the original test strip and the irregular shape of the test strip. Therefore, during cutting, it is necessary to manually measure and calibrate multiple times to make its edge flat and in a horizontal and regular state. This operation will result in low work efficiency and is prone to errors. After multiple cuttings, the state is not flush, resulting in waste of resources; If a laser lamp is used for calibration to ensure the cutting degree, there will be a problem of color change in the later error when the laser irradiates the test strip.

[0003] In view of the above problems, a test strip cutting device and method are proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a test strip cutting device and method, which solves the problem that the existing cutting device affects the later use of the test strip by laser alignment in the background art, and has the beneficial point of being convenient for sorting according to the size of the test strip.

Magnetic attraction blocks are fixedly connected to the opposite sides of the clamping plates. The magnetic attraction blocks are adsorbed and connected to the bottom plate.

[0007] As a further description of the above technical solution: The cutting mechanism includes a top seat, a cutting knife, a cutting block, and a distance gear. A top seat is fixedly connected to the corners of the upper surface of the base through a column. A cutting block is slidably connected to the lower surface of the top seat through a hydraulic cylinder. An installation groove is provided inside the cutting block.

[0008] As a further description of the above technical solution: A calibration mechanism is provided on the opposite sides of the rack. The calibration mechanism includes a calibration rope and a calibration block. A calibration block is fixed to the outside of the rack through the calibration rope.

[0009] As a further description of the above technical solution: A lifting groove for the sliding of the top plate is provided at the top end of the three-dimensional plate. A lifting rod is rotatably connected to the inside of the lifting groove. The lifting rod passes through the top plate and is threadedly connected thereto.

[0010] As a further description of the above technical solution: The number of the extrusion mechanisms is two groups, distributed on both sides of the reference seat. One group of the extrusion mechanisms close to the column is in contact with the reference seat.

[0011] As a further description of the above technical solution: An infrared distance sensor is fixedly connected to the inside of the clamping plate.

[0012] A test strip cutting method, using the aforementioned test strip cutting device, the test strip cutting method includes the following steps: S1.

Specific implementation mode

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0019] Combined with Figure 1 , Figure 2 and Figure 3 , the test strip cutting device of this embodiment includes: a base 1; an extrusion mechanism 2, with the extrusion mechanism 2 provided above the base 1; a cutting mechanism 3, fixedly connected to the base 1 through a column 4; a origin seat 201 fixedly connected to the upper surface of the base 1, and the origin seat 201 is the origin of the device, facilitating the later statistics of data and the adjustment of distance; a origin seat 201 is fixedly connected to the upper surface of the base 1, and a slide rail 202 is fixedly connected to one side of the origin seat 201, and a data block 203 is slidably connected to the outer side wall of the slide rail 202. A central mechanism 5 is provided inside the three-dimensional plate 204, and a bottom plate 205 is slidably connected to one side of the three-dimensional plate 204 close to the origin seat 201, and a top plate 206 is slidably connected to the top of the three-dimensional plate 204; during use, the test strip is moved between the bottom plate 205 and the top plate 206 through the slide rail 202 to the origin seat 201 for fixed positioning, and then the three-dimensional plate 204 is used to adapt to test strips of different shapes to make its cutting in a regular quadrilateral shape.

[0020] Combined with Figure 1 and Figure 2, the upper surface of the data block 203 is rotatably connected with an internal gear 207. Above the data block 203, there is a three-dimensional plate 204. The bottom of the three-dimensional plate 204 is meshed and connected with the internal gear 207 through an external gear 208. The meshing of the internal gear 207 and the external gear 208 enables the three-dimensional plate 204 to rotate, so as to adapt to original test strips of different shapes, facilitating subsequent cutting into quadrilaterals.

[0021] Combined with Figure 2 , inside the three-dimensional plate 204, there is a central groove 505. Inside the central groove 505, a double-threaded cylinder 501 is rotatably connected. On both sides inside the double-threaded cylinder 501, there are screw rods 502 threadedly connected. The helix directions on both sides inside the double-threaded cylinder 501 are opposite, so as to drive the two screw rods 502 to move relatively or away from each other when rotating. The opposite ends of the screw rods 502 are fixedly connected with clamping plates 503. The clamping plates 503 penetrate through the central groove 505 and are fixed to the screw rods 502 at one end, thus realizing the limit of the movement of the screw rods 502 to make them move relatively. And the clamping plates 503 are located on the outside to realize the extrusion of the outside of the test strip. On the opposite sides of the clamping plates 503, there are magnetic attraction blocks 504 fixedly connected. The magnetic attraction blocks 504 are adsorbed and connected with the bottom plate 205; at the top of the three-dimensional plate 204, there is a lifting groove 7 for the sliding of the top plate 206. Inside the lifting groove 7, a lifting rod 8 is rotatably connected. The lifting rod 8 penetrates through the top plate 206 and is threadedly connected with it. By controlling the height of the top plate 206 through the lifting rod 8, the upper surface of the test strip can be contacted.

[0022] Combined with Figure 3 , Figure 4 and Figure 5 , at the corners of the upper surface of the base 1, a top seat 301 is fixedly connected through columns 4. The lower surface of the top seat 301 is slidably connected with a cutting block 303 through a hydraulic cylinder 305. Inside the cutting block 303, there is an installation groove 306. Inside the installation groove 306, a distance gear 304 is rotatably connected. Inside the installation groove 306, a rack 307 is slidably connected. The rack 307 is meshed and connected with the distance gear 304. On the opposite sides of the rack 307, there are engaging blocks 308 fixedly connected. The engaging blocks 308 are detachably connected with a cutting knife 302. The upper and lower sides of the distance gear 304 are both meshed and connected with a rack 307, so that the moving directions of the two racks 307 are opposite. One side of the rack 307 controls one end of the engaging block 308, thus realizing the adjustment of the distance between the cutting knife 302 and the distance gear 304.

[0023] Combined with Figure 1 and Figure 3, the number of the extrusion mechanisms 2 is two groups, which are distributed on both sides of the origin base 201. One group of extrusion mechanisms 2 close to the column 4 is in contact with the origin base 201. The two groups of extrusion mechanisms 2 can quickly fix and limit the test strip when both sides of the test strip are irregular, and form a regular quadrilateral at the origin base 201. An infrared distance sensor 9 is fixedly connected inside the clamping plate 503. The infrared distance sensor 9 cooperates with the origin base 201 to measure the distance of the irregular edge and form a regular quadrilateral cutting scheme in cooperation with the cutting block 303.

[0024] Combined with Figure 1 , Figure 3 , Figure 4 and Figure 5 , a calibration mechanism 6 is provided on the opposite sides of the rack 307. A calibration block 602 is fixed to the outside of the rack 307 through a calibration rope 601. Calibration ropes 601 are fixed to both sides of the rack 307 close to the engaging block 308 above. Then there is a calibration block 602 vertically. Due to gravity, the calibration block 602 vertically downward can form a traditional instrument for measuring straightness, which can avoid the problem of the influence of the existing laser measuring horizontal line on the antigen-antibody; an infrared distance sensor 9 is fixedly connected inside the clamping plate 503. The edge length of the test strip can be measured through the infrared distance sensor 9, which is convenient for later calculation and use.

[0025] Combined with Figure 6 , the test strip cutting method of this embodiment adopts Figure 1-5 the test strip cutting device shown, and this test strip cutting method includes the following steps: S1. Place the test strip to be cut on the bottom plate 205 on one side of the three-dimensional plate 204, and then make the edge of the test strip contact with the three-dimensional plate 204 and make the three-dimensional plate 204 rotate to keep the same plane line with it; S2. Rotate the double-threaded cylinder 501 inside the three-dimensional plate 204 to make the two clamping plates 503 move relatively, so that the magnetic attraction block 504 contacts the bottom plate 205 and squeezes the test strip to make it located at the central position; S3. Push the three-dimensional plate 204 through the slide rail 202 to make one side of the test strip located at the origin base 201, and then make the other side of the test strip contact with the second group of three-dimensional plates 204 to form a squeezing and closing state; S4. Move the cutting block 303 downward through the hydraulic cylinder 305, and at the same time drive the rack 307 to move through the distance gear 304. The rack 307 above penetrates the cutting block 303 and contacts the three-dimensional plate 204 to realize the minimum distance ranging and adjust the width of the test strip. The rack 307 below drives the cutting knife 302 to move for broadband adaptation, and then performs cutting.

[0026] Working principle: Move the extrusion mechanism 2 on the side far from the column 4 to the farthest position of the three-dimensional plate 204 through the slide rail 202. Then, place the test paper to be cut on the bottom plate 205 and position it in the middle through the central mechanism 5. The operation mode of the central mechanism 5 is that the double-threaded cylinder 501 rotates, driving the two screw rods 502 to move relatively towards and away from each other. Then, move the clamping plate 503 to contact the bottom plate 205 to form edge contact fixation of the test paper. Then, push the other side of the test paper into the second extrusion mechanism 2 and adjust it according to the edge of the test paper. Then, the infrared distance sensor 9 can detect the edge width of the original test paper. The correction block 602 is driven vertically by the correction rope 601, and the infrared distance sensor 9 can irradiate the correction block 602, so as to detect whether the cutting knife 302 is offset, ensuring the flatness of the later cutting. Rack bars 307 are meshed and connected to both the upper and lower sides of the distance gear 304, so that the moving directions of the two rack bars 307 are opposite. One side of the rack bar 307 controls one end of the engaging block 308, thereby realizing the distance adjustment between the cutting knife 302 and the distance gear 304. By observing the distance between the rack bar 307 and the three-dimensional plate 204, the distance from the origin seat 201 can be observed. Lower the hydraulic cylinder 305 to make the cutting knife 302 perform the cutting work.
