The working process of the invention is briefly described as follows:
when the sample rack loading device works, the control system sends a signal to the second stepping motor 3.4 to drive the second push plate 3.7 to translate towards the inlet end of the loading channel along the first through groove 3.2, the second push plate 3.7 drives the first driving block 7.3 to extrude the pulley 7.2 so as to drive the driving rod 7.1 to rotate in the translation process, the tension spring 7.4 on the driving rod 7.1 is in a stretching state, the driving rod 7.1 drives the first guide plate 6.2 to move towards the second guide plate 6.3, according to the connecting rod driving principle, the second guide plate 6.3 is driven by the third connecting rod 7.6 to move towards the first guide plate 6.2, the distance between the first guide plate 6.2 and the second guide plate 6.3 is reduced, closing is realized, the pressure spring 6.5 between the first guide plate 6.2 and the first guide plate 6.3 is in a compression state, an experimenter can place a plurality of sample racks at any position of the guide mechanism, and the placing efficiency is improved. When the loading full-bin sensor 1.3 sends a full-bin signal to the control system, the sample rack is stopped being placed, when the flip sensor 1.5 sends a signal to the control system, the control system sends a signal to the second stepping motor 3.4 to drive the second push plate 3.7 and the first driving block 7.3 to move to the second pushing mechanism, the driving rod 7.1 is driven to rotate to the original position by the disappearance of the pulling force received by the pulling spring 7.4, the pressure received by the pressure spring 6.5 disappears in the process of resetting the driving rod 7.1, the first guide plate 6.2 and the second guide plate 6.3 are driven to return to the original positions by the pressure spring 6.5 in the process of resetting, at the moment, the first guide plate 6.2 and the second guide plate 6.3 are matched with the grooves at the bottom of the sample rack to perform anti-reverse positioning on the sample rack, the second push plate 3.7 pushes the sample rack to move to the second pushing mechanism, when the second push plate 3.7 reaches the limit position, the limit sensor 3.9 sends a signal to drive the second push plate 3.4 to rotate to further drive the second push plate to move to the second pushing mechanism to perform repeated opening and closing operation on the sample rack.
When the sample rack is conveyed to the bottom plate 1.1 at the position corresponding to the second pushing handle mechanism, the control system sends signals to the third pushing motor 4.5 and the linear stepping motor 4.9, the linear stepping motor 4.9 drives the two pushing handles 4.11 to incline, so that one end of each pushing handle 4.11 extends upwards from the second through groove 4.2 to the upper surface of the bottom plate 1.1, the third pushing motor 4.5 drives the pushing handle 4.11 unit to move towards the sampling line conveying unit along the second through groove 4.2, the pushing handle 4.11 pushes the sample rack to move towards the sampling line conveying unit in the moving process, when the sample rack reaches the sampling line area, the in-place sensor 1.6 sends a signal to the control system, the control system sends a signal to the linear stepping motor 4.9 to drive the pushing handle 4.11 to return to the original position, and the third pushing motor 4.5 drives the pushing handle unit to return to the original position to move back and forth repeatedly, so as to relay the sample rack conveyed by the first pushing handle mechanism. After the sample rack is loaded in place, the control system sends a signal to the first stepping motor 2.3 according to the actual position of the sample rack bar code, when the sample rack bar code is on the front side, the first stepping motor 2.3 drives the first push plate 2.6 to drive the sample rack to transversely translate, in the transverse translation process of the sample rack, the height sensor 1.9 detects the height of the sample pipe and transmits the signal to the control system, the static removing brush 1.14 removes static electricity on the sample pipe, the code reader 1.8 collects information of the sample rack through the scanning window 1.10, then the control system sends a signal to the code reader 1.8 to scan the sample pipe, after scanning the code, the sampling needle quickly extends into the sample pipe from the sampling hole 1.11 to collect a sample in the sample pipe; when the bar code of the sample frame is at the rear side, the first stepping motor 2.3 drives the first push plate 2.6 and the pull plate 2.7 to transversely translate until the bar code of the sample frame runs to the position of the scanning window 1.10, the code reader 1.8 acquires information of the sample frame, the control system sends a signal to the first stepping motor 2.3 after the information of the sample frame is acquired to drive the first push plate 2.6 and the pull plate 2.7 to move in opposite directions, the pull plate 2.7 transmits the sample frame to a preset position in the moving process, and then the steps are repeated to acquire information and sample and analyze the sample in the sample tube.
When the sample rack moves the outlet end of the sampling line, the output position sensor 1.7 sends a signal to the control system to drive the carrying-out motor 5.3 to drive the third push plate 5.7 and the push rod 5.8 to move, the push rod 5.8 penetrates through the third through groove 5.9 to push the sample rack to move three sample rack positions to the outlet end of the carrying-out channel, and then the control system sends a signal to the carrying-out motor 5.3 to drive the third push plate 5.7 and the push rod 5.8 to return to the original positions to wait for the conveying of the next sample rack. When the sample rack is fully discharged from the carrying-out channel, the carrying-out full-bin sensor 1.4 sends out a full-bin signal to remind the worker to take out the sample rack.
The emergency treatment positions are positioned at the outlet end of the loading channel and the sampling line area, and the emergency treatment positions have 6 sample racks; when an emergency sample needs emergency treatment, the control system firstly judges whether 6 sample frame positions are reserved in an emergency treatment position or not, when the 6 sample frame positions are reserved, a worker can directly place the emergency sample in the emergency treatment position, and information acquisition and sampling analysis are carried out on the emergency sample according to the operation; when the loading channel can not meet the requirement of reserving 6 sample rack positions, the control system sends a signal, an operator can directly take out a sample rack on an emergency treatment position, or the control system sends a signal to the second pushing handle mechanism, the linear stepping motor 4.9 drives one end, connected with the sampling line conveying unit, of the pushing handle 4.11 to extend upwards out of the upper surface of the bottom plate 1.1 along the second through groove 4.2, the third step motor 4.5 pushes the pushing handle unit to push the sample rack to move towards the inlet end of the loading channel along the second through groove 4.2, six sample rack positions are reserved, an emergency sample rack is placed on the emergency treatment position, then the second pushing handle mechanism conveys the emergency sample to a sampling area, and then information acquisition, sampling analysis and sample rack loading operation are repeated.
