[0002] The full self-service nucleic acid detection machine can be used in the field of large-scale nucleic acid collection and detection. Currently, there are two kinds of large-scale nucleic acid collection and detection technologies. The first kind is to collect human tissue cells by using a throat swab and then send the collected sample to a special detection institution to obtain a detection result by using a nucleic acid amplification technology. The second kind is to use a mechanical arm to replace manual nucleic acid collection, and the nucleic acid detection process is almost the same as the first kind of large-scale nucleic acid collection and detection technology.

[0041] As shown in Figures 7-10 The planar moving device 3 comprises a sliding rail 301, first screw nuts 302 are arranged on both sides of the sliding rail 301, the first screw nuts 302 are connected with first screw rods 303, end portions of the first screw rods 303 are connected with a second motor 304, the second motor 304 is fixed on the shell 1, and as known from the working principle of the screw rod, when the second motor 304 drives the first screw rods 303 to rotate, the first screw rods 303 are matched with the first screw nuts 302, so that the sliding rail 301 moves up and down on the first screw rods 303; a bottom plate 305 is slidably arranged on the sliding rail 301, a pulley 306 is arranged on a lower surface of the bottom plate 305, the pulley 306 is connected with the sliding rail 301, and a side surface of the pulley 306 is connected with the sliding rail 301; a transition plate 307 is connected above the bottom plate 305, a third motor 308 is arranged on the transition plate 307, the third motor 308 is connected with the pulley 306, the third motor 308 drives the pulley 306 to rotate, the transition plate 307 is locked with the bottom plate 305, and the bottom plate 305 can slide horizontally on the sliding rail 301, so that when the third motor 308 drives the pulley 306 to rotate, the side surface of the pulley 306 rubs against the sliding rail 301, so that the bottom plate 305 can move left and right on the sliding rail 301; an operation table 309 is slidably arranged on the transition plate 307, specifically, a fourth motor 310 is arranged on the transition plate 307, the number of the fourth motors 310 is two, and the fourth motors 310 are located at front and rear edges of the transition plate 307; the fourth motors 310 are connected with gears 311, a rack 312 is arranged on a lower surface of the operation table 309, and the gears 311 are connected with the rack 312 in meshing, so that the fourth motors 310 drive the gears 311 to rotate, and through the mutual relationship between the gears 311 and the rack 312, the operation table 309 can move forward and backward on the transition plate 307.

[0042] The operating platform 309 is located in front of the test bag delivery channel 202. The start of the fourth motor 310 enables the operating platform 309 to move back and forth relative to the transition plate 307. The start of the third motor 308 enables the operating platform 309 to move left and right on the slide rail 301. The start of the second motor 304 enables the operating platform 309 to move up and down, thereby enabling the operating platform 309 to go to different positions of the test bag delivery channel 202 to pick up test bags.

One of the two sixth motors 604 is used for unwinding the film body, and the other is used for winding the film body. The two sixth motors 604 rotate in the same direction to drive the rotation of the rod body 605, so that the film body moves. The hot melting assembly 602 corresponds to the position of the clamping groove 3091. When the test strip after sampling is placed in the clamping groove 3091, the compression assembly 601 drives the hot melting assembly 602 to press down, and the film body is pressed down to cover the test strip. Then the compression assembly 601 drives the hot melting assembly 602 to rise, and at the same time, the planar moving device 3 moves away, and the two sixth motors 604 rotate at the same time to drive the film body to move, waiting for the next round of hot melting and film covering work.
