The test paper winding unit is disposed on the base, and the coating unit is disposed on the base. The coating unit is located at the middle rear position of the test paper winding unit.

[0006] The test strip winding unit includes a first motor, a first rotating base, an unwinding roller, a second motor, a second rotating base, a winding roller, a fixed shaft, a positioning roller, a first limiting shaft, a second limiting shaft, and a test strip. The first motor is fixedly mounted on the left side of the base. The first rotating base is fixedly mounted on the output shaft of the first motor. The unwinding roller is inserted and pulled above the first rotating base. The second motor is fixedly mounted on the right side of the base. The second rotating base is fixedly mounted on the output shaft of the second motor. The winding roller is inserted and pulled above the second rotating base. The fixed shaft is fixedly mounted in the middle of the base. The positioning roller is rotatably mounted on the fixed shaft. The first limiting shaft is fixedly mounted on the base and located at a 45-degree angle to the left rear. The second limiting shaft is fixedly mounted on the base and located at a 45-degree angle to the right rear. One end of the test strip is wound onto the unwinding roller, and the other end is wound around the test strip and onto the winding roller.

[0007] Preferably, the application unit includes a motor three, a rotating seat three, a spring, a socket and a cotton swab. The motor three is fixedly mounted on the base and located behind the fixed shaft. The rotating seat three is fixedly mounted on the output shaft of the motor three. The spring is fixedly mounted on the outer side of the rotating seat three. The socket is fixedly mounted above the rotating seat three. The cotton swab insertion and removal limit is located inside the socket.

[0008] To achieve better coating results, the test strip is designed with a double-layer structure, with the bottom layer being a release paper strip and the outer layer being reagent paper segments with sequential numbers.

[0009] To achieve precise rotation more quickly, the first and second rotating seats are circular at the bottom and have square pillars on top.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention proposes an automatic swab coating device, including a base 1 and an automatic coating structure 2. The automatic coating structure 2 is disposed on the base 1 and includes a test paper winding unit 3 and a coating unit 4. The test paper winding unit 3 is disposed on the base 1 and the coating unit 4 is disposed on the base 1. The coating unit 4 is located at the middle rear position of the test paper winding unit 3.

[0022] The test paper winding unit 3 includes a first motor 5, a first rotating seat 6, an unwinding roller 7, a second motor 8, a second rotating seat 9, a winding roller 20, a fixed shaft 10, a positioning roller 11, a first limiting shaft 12, a second limiting shaft 13, and a test paper belt 14. The first motor 5 is fixedly mounted on the left side of the base 1. The first rotating seat 6 is fixedly mounted on the output shaft of the first motor 5. The unwinding roller 7 is inserted above the first rotating seat 6. The second motor 8 is fixedly mounted on the right side of the base 1. The first motor 5 and the second motor 8 rotate synchronously. The second rotating seat 9 is fixedly mounted on the output shaft of the second motor 8. The first rotating seat 6 and the second rotating seat 9 have circular bottoms and square pillars on top. The winding roller 20 is inserted above the second rotating seat 9. The unwinding roller 7 and the winding roller 20 are arranged in a circular I-beam shape with the central... A square hole is provided in the center. The fixed shaft 10 is fixedly located in the middle of the base 1. The positioning roller 11 is rotatably mounted on the fixed shaft 10. The rotating seat 6, the winding roller 20 and the positioning roller 11 are set at the same height. The limiting shaft 12 is fixedly mounted on the base 1 and located at a position 45 degrees to the left rear. The limiting shaft 23 is fixedly mounted on the base 1 and located at a position 45 degrees to the right rear. One end of the test strip 14 is wound on the unwinding roller 7 and the other end is wound around the test strip 14 and mounted on the winding roller 20. The test strip 14 is set in a double-layer structure. The bottom layer is a release paper strip and the outer layer is a reagent paper segment with sequential numbering. The limiting shaft 12 and the limiting shaft 23 are set on both sides in front of the positioning roller 11 and close to the positioning roller 11, so that the test strip 14 slides against the outer circle of the positioning roller 11.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the application unit 4 includes a motor 15, a rotating seat 16, a spring 17, a socket 18, and a cotton swab 19. The motor 15 is fixed on the base 1 and located behind the fixed shaft 10. The rotating seat 16 is fixed on the output shaft of the motor 15. The spring 17 is fixed on the outer side of the rotating seat 16. The socket 18 is fixed above the rotating seat 16. The cotton swab 19 is inserted and removed within the socket 18. The head of the cotton swab 19 rotates and slides across the test strip 14 outside the positioning roller 11, and the area of ​​the cotton swab 19 sliding across the test strip 14 is consistent with the area of ​​the test strip 14.

[0024] In practical use, the second motor 8 rotates synchronously and in the same direction as the first motor 5. The second motor 8 drives the winding roller 20 on the rotating seat 29 to take in the test strip 14, while the first motor 5 drives the unwinding roller 7 on the rotating seat 16 to release the test strip 14. At this time, the test strip 14 is guided by the first limiting shaft 12 and the second limiting shaft 13 to wrap around and adhere to the outside of the positioning roller 11, so that the reagent paper on the outside of the test strip 14 stops between the first limiting shaft 12 and the second limiting shaft 13. At the same time, the cotton swab 19 is used to pick up the sample, and then the swab stick on the cotton swab 19 is inserted into the socket 18. At this time, the motor 315 drives the rotating seat 316 to rotate, which in turn drives the cotton swab 19 inserted into the socket 18 on the spring 17 to rotate one revolution. This causes the cotton swab 19 to apply the sample to the reagent paper on the outside of the test strip 14. Thus, each rotation ensures that the cotton swab 19 evenly coats the test strip 14. After the coating is completed, the test strips 14 with the order are removed, and then the comparison is recorded. This improves the coating quality and efficiency. The above is the entire process of using the device for automatic swab coating.
