The using method of the automatic cleaning device for the chromatographic sample bottle comprises the following steps: when the chromatographic sample bottle is cleaned, pure water is filled in the first cleaning tank 402, and ethanol is filled in the second cleaning tank 403; the pure water in the first washing tank 402 is replaced periodically, and the ethanol in the second washing tank 403 is replaced periodically. For the chromatographic sample bottle 5 with special waste liquid, more proper cleaning solution can be replaced and used, and if the bottle body needs to be cleaned for many times by utilizing various cleaning solutions, the number of ultrasonic cleaning machines can be increased.

Working principle: as shown in fig. 2, a plurality of chromatographic sample bottles 5 loaded with waste liquid are placed in the vibration plate 100, and the vibration plate 100, the second motor 202, the water pump 301, the first ultrasonic cleaner 400, the second ultrasonic cleaner 401, the first conveyor 404, and the second conveyor 405 are operated by the controller. The vibration plate 100 makes the chromatographic sample bottles 5 enter the feeding channel 101, a plurality of chromatographic sample bottles 5 are sequentially arranged, rise up along the feeding channel 101 and enter the upper end of the slideway 102 from the feeding notch 103, at this time, the chromatographic sample bottles 5 have two states, namely, the bottle cap is in the lower state, the bottle body is in the upper state, and the bottle cap is in the upper state and the bottle body is in the lower state.

As shown in fig. 3 and 4, under the action of gravity, the chromatographic sample bottle 5 rolls down along the slideway 102, the annular groove between the bottle body and the bottle cover corresponds to the rib 112, the chromatographic sample bottle 5 on the bottle cover continuously rolls down, the time from passing under the first distance sensor 113 is very short, the time of the signal generated on the first distance sensor 113 is very short (such as 0.2 s), and the time of the signal received by the controller 6 is short without any instruction; the chromatographic sample bottle 5 with the bottle cap below and the ribs 112 prop against the bottle body, so that the chromatographic sample bottle 5 cannot roll downwards, the chromatographic sample bottle 5 stays at the ribs 112 for a longer time (for example, more than 1 s), the first distance sensor 113 outputs a longer-time signal to the controller 6, and the controller 6 receives the longer-time signal and then enables the first air cylinder 109 to extend and retract rapidly through the first electromagnetic valve 110. When the first cylinder 109 is extended, the chromatographic sample bottle 5 is moved away from the slide way 102 from the first through hole 107 by the push plate 111 and falls back into the vibration plate 100 again. Thereby, it is ensured that all chromatographic sample vials 5 passing through the ribs 112 are capped.

As shown in fig. 6 and 7, the chromatographic sample bottle 5 separated from the rib 112 continues to roll down until contacting with the limit piece 127, the chromatographic sample bottle 5 is positioned below the second distance sensor 129, the second distance sensor 129 generates a signal, after receiving the signal, the controller 6 firstly extends the second cylinder 121 through the second electromagnetic valve 122, the first motor 123 is driven to move towards the slideway 102 through the sliding plate 120, the rotating plate 124 contacts with the bottle cap, and the convex tip 125 is pricked into the bottle cap; then the controller 6 starts the first motor 123, the first motor 123 drives the rotary plate 124 to rotate for a plurality of weeks, the bottle cap rotates out, the bottle body is not moved due to the large friction force between the bottle body and the rubber plate 116, the bottle cap gives a reaction force in the process of rotating out the bottle cap, the second cylinder 121 has a retraction with a certain stroke, and the pressure of the second cylinder 121 cannot be too large in order to ensure the smooth retraction of the second cylinder 121, and the bottle cap is supplied with air by adopting a low-pressure air source or a small-cylinder-diameter cylinder; then, the controller 6 contracts the second cylinder 121 by the second solenoid valve 122 to pass the rotating plate 124 between the two release shafts 126, and the bottle cap is blocked by the release shafts 126 to be separated from the rotating plate 124, and the bottle cap falls off. Preferably, the cap is prevented from stacking, and the first bracket 118 should be provided with a hole for the cap to pass through when it is dropped. The remaining vials may pass under the stop tab 127 and continue to roll down until stopped by the second stop 205.

As shown in fig. 8 and 9, when the bottle is at the second baffle 205, the rear half of the bottle is on the bottom plate of the slide 102, and the front half is supported by the support sleeve 203 so that the bottle does not tilt or fall. The second motor 202 makes the carousel 201 rotate, drives the support cover 203 and rotates, and when dodging breach 204 and entering into the bottle below, the bottle front portion loses the support, and the upset down falls to wash on the needle 304, along with the rotation of carousel 201, a plurality of bottles cover in proper order on a plurality of washing needles 304.

The controller 6 opens the third solenoid valve 305 on the rinse needle 304 exiting from below the discharge end of the slide 102, i.e., closes the third solenoid valve 305 on the rinse needle 304 reaching the stripper plate 308, depending on the initial angle of each rinse needle 304 relative to the discharge end of the slide 102. Corresponding to a bottle body on a specific flushing needle 304, under the zero angle of the second motor 202, assuming that the flushing needle 304 needs to rotate by an angle A when reaching the discharge end of the slideway 102 and needs to rotate by an angle B when reaching the stripper plate 308, after the second motor 202 rotates by an angle A+10 DEG in a period of 360 DEG of rotation of the second motor 202, the third electromagnetic valve 305 on the flushing needle 304 is opened, and after the second motor 202 rotates by an angle B-10 DEG, the third electromagnetic valve 305 on the flushing needle 304 is closed, so that the bottle body is flushed in the path from the discharge end of the slideway 102 to the stripper plate 308. When the third electromagnetic valve 305 is opened, water of the water pump enters the flushing needle 304 through the rotary joint 300, the corresponding third electromagnetic valve 305 and the corresponding pipeline 303 to flush the inner peripheral surface of the bottle body, and the inner bottom surface of the bottle body is flushed by splash water. The turntable continues to rotate until the turntable is near the stripper plate 308, stopping flushing; the rotary table 201 continues to rotate, the lower end of the bottle body contacts with the inclined surface 309, so that the bottle body rises, as shown in fig. 12, because the stripper plate 308 is on the inner side of the flushing needle 304, the bottle body tilts outwards in the rising process until the bottle body reaches the highest position, and the bottle body overturns from the corresponding avoiding notch 204 and falls onto the first conveyor 404 of the first cleaning tank 402. Preferably, a sloping plate with a U-shaped cross section for guiding is arranged on the first cleaning tank 402, so that the bottle body can fall off more gradually after leaving the avoidance gap 204.

The bottle body is in the first cleaning tank 402, is conveyed by the first conveyor 404 to leave the first cleaning tank 402 after being cleaned by pure water in an ultrasonic manner, falls onto the second conveyor 405 of the second cleaning tank 403, is conveyed by the second conveyor 405 into the container 406 after being cleaned by ethanol in the second cleaning tank 403 in an ultrasonic manner. The whole cleaning process is completed, and the cleaned bottle body can be recycled after drying operation. The conveyor is preferably a stainless steel mesh belt conveyor, and the conveying surface is uneven so as to avoid rolling of the bottle body.

As for the connection harness between the third solenoid valve 305 and the controller 6, since the third solenoid valve 305 rotates around the turntable 201, it is necessary to provide an electrically conductive slip ring on the connection harness to avoid knotting thereof.
