Description

Technical Field

[0001] The invention relates to the technical field of automated detection, and in particular to an integrated storage system for cleaning and filling absorption bottles. Background Art

[0002] An atmospheric absorption bottle is a glass container that uses a solution absorption method to collect pollutants in the atmosphere. Compared with ordinary glass containers, it has a more complex structure. When in use, it is necessary to fill the bottle with an absorption liquid of a specific composition, and ensure that the atmospheric absorption bottle has a qualified bottle resistance. When conducting air testing, it is necessary to add absorption liquid to the absorption bottle, and then blow the collected sample into the absorption bottle to mix and extract it with the absorption liquid. After the extraction is completed, 1mL, 2mL, 5mL, 10mL or all of the sample liquids are taken according to the needs and injected into the colorimetric tube for testing. Since the entire operation process has many steps, it requires several or even more than a dozen people to work together. The detection efficiency is low and the labor cost is high, which makes it difficult to meet the needs of large-scale testing. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an integrated storage system for cleaning and filling absorption bottles, which has the advantages of reducing labor costs and improving detection efficiency.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] An integrated storage system for cleaning and filling absorption bottles, comprising:

[0006] A liquid storage box, wherein an absorption bottle is embedded in the liquid storage box, and a liquid inlet and a liquid outlet connected to the absorption bottle are respectively provided on two sides of the liquid storage box;

[0007] A sampling storage conveyor line for transferring a sampling box, wherein the sampling box is loaded with a plurality of the liquid storage tanks;

[0008] A liquid adding device for filling the liquid storage tanks with absorption liquid one by one, the liquid adding device comprising: a liquid adding rack, a liquid adding sealing mechanism carried on the liquid adding rack for labeling the liquid storage tanks and installing sealing caps, a quantitative liquid adding mechanism carried on the liquid adding rack for connecting with the liquid storage tanks before sealing to add absorption liquid, and a liquid adding clamping manipulator for taking and placing the liquid storage tanks from the sampling box one by one to the liquid adding sealing mechanism;

[0009] An extraction transfer device connected to the sampling storage conveyor line and used for transferring the test liquid in the liquid storage tank after extraction to the colorimetric tube, the extraction transfer device comprises: a transfer conveyor line, a transfer and delivery mechanism for grabbing the liquid storage tanks one by one from the sampling storage conveyor line to the transfer conveyor line, a cap removal mechanism for removing the sealing cap on the liquid storage tank, a liquid discharge mechanism for pouring out the extraction sample liquid in the liquid storage tank, a transfer liquid receiving mechanism for receiving the extraction sample liquid, an extraction clamping manipulator for grabbing and transferring the colorimetric tube, and a quantitative liquid taking mechanism for quantitatively drawing the extraction sample liquid from the transfer liquid receiving mechanism and injecting it into the colorimetric tube, a colorimetric tube storage system is provided on one side of the extraction transfer device; and

[0010] An automatic cleaning device for cleaning a liquid storage tank after extraction and transfer is completed, the automatic cleaning device comprising: a cleaning conveyor line connected to the transfer conveyor line, a cleaning mechanism for aerating and cleaning the liquid storage tank, and a label removal mechanism for removing labels from the liquid storage tank. A liquid storage tank storage system is provided on one side of the automatic cleaning device.

[0011] To implement the above technical solution, by setting up a standardized liquid storage box, it is convenient to carry out centralized transportation, storage, transfer and other processes of the absorption bottles. The liquid storage boxes after sampling are neatly stacked in the sampling box, and the sampling boxes are transferred and transported by the sampling storage conveyor line; when adding liquid, the liquid storage box is clamped and placed on the liquid adding sealing mechanism by the liquid adding clamping robot, and then the liquid adding mechanism is used to first label the liquid storage box, and then the liquid storage box is docked with the quantitative liquid adding mechanism to add a quantitative absorption liquid, and then the liquid adding sealing mechanism installs sealing caps at the liquid inlet and liquid outlet of the liquid storage box for sealing, so as to prevent outside air from entering the absorption bottle during the static extraction of the absorption liquid and affecting the test results. After the sealing is completed, the liquid adding clamping robot puts the liquid storage box back to its original position and puts in a new liquid storage box, and then the sampling box is transferred to the extraction and transfer mechanism through the sampling storage conveyor line;

[0012] When the extraction action is performed, the transfer and delivery mechanism grabs the liquid storage boxes one by one to the transfer conveyor line, and the transfer conveyor line moves the liquid storage boxes forward. First, the sealing caps on the water inlet and the water outlet of the liquid storage box are taken out by the cap removal mechanism, and then the liquid discharge device is passed. At this time, if all the extraction sample liquid is taken, the corresponding colorimetric tube is grabbed from the colorimetric tube storage system by the extraction clamping manipulator and placed at the liquid discharge device. The liquid discharge device pours the extraction sample liquid in the liquid storage box into the colorimetric tube and then puts it back into the colorimetric tube storage system; and if a quantitative extraction sample liquid is to be taken, the extraction sample liquid is first injected into the transfer liquid receiving mechanism, and then the extraction clamping manipulator grabs the corresponding colorimetric tube from the colorimetric tube storage system, and the quantitative liquid taking mechanism draws the extraction sample liquid of the corresponding specification from the transfer liquid receiving mechanism and injects it into the corresponding colorimetric tube. After completion, it is put back into the colorimetric tube storage system.

[0013] The liquid storage tank after liquid extraction is transferred to the cleaning conveyor line. The absorption bottle in the liquid storage tank is aerated and cleaned when passing through the cleaning mechanism. Then the label on the liquid storage tank is removed by the label removal mechanism. The liquid storage tank is stored in the liquid storage tank storage system for subsequent use. The above process realizes automated liquid addition, extraction, transfer, cleaning, label removal, storage and other processes. Only 2-3 people are needed to control and replace the absorption liquid concentrate bottle, take and place the colorimetric tube and other processes throughout the process, which greatly reduces labor costs, improves detection efficiency and meets the needs of large-scale detection.

When the first carrying plate rotates until the liquid storage tank is located at the fitting opening and closing mechanism, the opening and closing driving electric cylinder drives the opening and closing air clamp to move to the label cover, and the opening and closing air clamp is relatively clamped to insert the opening and closing latch under the label cover, and then the opening and closing driving electric cylinder retracts to flip open the label cover, and then the label picking and placing two-axis servo mechanism drives the label picking and placing suction head to move to the printing outlet of the label printing device, and sucks a label to move it under the label cover, and then the opening and closing air clamp is released to close the label cover again, thus completing the label placing process.

When the liquid storage box moves to the cap removing mechanism, the cap removing clamping cylinder drives the cap removing clamping air clamp to move, and the cap removing clamping air clamp clamps the liquid storage box and inserts the supporting protrusion into the socket. Then the cap removing transfer cylinder drives the cap removing air clamp to move to the place where the card holder slot is embedded in the liquid inlet and the liquid outlet. When the cap removing air clamp opens, the sealing caps on the liquid inlet and the liquid outlet are pulled out and fall into the collection cover, and the cap removing process is completed.

[0033] After the cap is removed, the transfer conveyor line transfers the liquid storage tank to the liquid discharge mechanism. If all the extracted sample liquid needs to be taken, the liquid storage tank is clamped by the liquid discharge clamping air clamp, and then the reversing motor drives the mounting plate to rotate 180°. The liquid discharge cylinder drives the liquid discharge sleeve moving sleeve to be inserted into the liquid inlet of the liquid storage tank. At the same time, the extraction clamping manipulator grabs the corresponding colorimetric tube from the colorimetric tube storage system and places it at the liquid outlet of the liquid storage tank. The liquid discharge vacuum pump is started to blow air into the absorption bottle, so that the extracted sample liquid in the absorption bottle can be blown into the colorimetric tube. After the dumping is completed, the extraction clamping manipulator puts the colorimetric tube back into the colorimetric tube storage system;

[0034] If a certain amount of extraction sample liquid is to be taken, the lifting and transfer cylinder drives the bracket to move up, and the transfer robot grabs the liquid receiving cup from the limit rack to the liquid outlet of the liquid storage box, and the liquid outlet vacuum pump blows all the extraction sample liquid in the absorption bottle into the liquid receiving cup. Then the transfer robot transfers the liquid receiving cup to the quantitative liquid taking mechanism, and then the extraction clamping robot grabs the corresponding colorimetric tube from the colorimetric tube storage system, arranges the pipette head through the gun head vibration plate and enters the transfer port of the gun head moving block, and the pipette head is supported by the support step, and then the gun head transfer cylinder drives the gun head moving block to move to the bottom of the pipette, and the two-axis servo mechanism of liquid taking drives the pipette gun to move so that the pipette head is covered on the The head is then inserted into the liquid receiving cup, and a certain amount of extraction sample liquid is taken out once by pressing the pipetting button of the pipette gun through the extension and contraction of the first pressing cylinder, and then the pipette gun is driven to move to the colorimetric tube through the two-axis servo mechanism for taking liquid, and the first pressing cylinder is extended and contracted to press the pipetting button of the pipette gun once again, and the extracted extraction sample liquid can be injected into the colorimetric tube. After the pipetting is completed, the two-axis servo mechanism for taking liquid drives the pipette gun to move above the pipetting waste collection bucket, and the second pressing cylinder is extended and contracted to press the pipette gun's suction head push button once to detach the pipette head, and then a new pipette head can be taken, and at the same time, the colorimetric tube after the pipetting is completed is put back into the colorimetric tube storage system by the transfer robot;

[0035] At the same time, after the transfer is completed, the remaining liquid in the liquid receiving cup is poured into the waste liquid bucket through the transfer robot, and then the liquid receiving cup is placed upside down on the limiting frame, the lifting and transferring cylinder is reset, and the cleaning nozzle is used to spray the liquid cup. After the spraying is completed, the liquid cup is blown dry by the drying nozzle, thereby realizing the automated cleaning process and facilitating the next use.

[0037] The label-removing mechanism comprises: an inclined label-removing and cover-opening electric cylinder, a label-removing and cover-opening air clamp fixed to the power output end of the label-removing and cover-opening electric cylinder, an open cover latch fixed to the clamping head of the label-removing and cover-opening air clamp, a label-removing and picking-and-placing two-axis servo mechanism, and a label-removing and picking-and-placing suction head fixed to the power output end of the label-removing and cover-opening two-axis servo mechanism.

[0038] To implement the above technical solution, the extracted sample liquid in the liquid storage tank is poured out and transferred to the cleaning conveyor line by the transfer conveyor line. When the liquid storage tank is transferred to the cleaning station, the liquid storage tank is clamped by the cleaning gas clamp, and the cleaning water is first injected into the absorption bottle through the sealing sleeve at the liquid inlet connected to the liquid inlet. The cleaning water can be tap water or pure water, which is switched by the switching valve. After the cleaning water is injected, the sealing sleeve at the liquid outlet is connected to the liquid outlet, and the cleaning vacuum pump is used to inject air into the absorption bottle for aeration to make the absorption bottle clean more thoroughly. After the cleaning is completed, the cleaning switching turntable is driven by the cleaning steering motor to rotate 180°, and the cleaning vacuum pump is used to inject air from the liquid inlet to blow out the cleaning water. This reciprocating process of tap water cleaning once and pure water cleaning three times is completed, and the cleaning process is completed;

[0039] Then the liquid storage tank is put back to the cleaning conveyor line, and when it moves to the label stripping mechanism, the label stripping cover opening electric cylinder drives the label stripping cover opening air clamp to move to the label cover, and the label stripping cover opening air clamp is relatively clamped to insert the cover opening pin under the label cover, and then the label stripping cover opening electric cylinder retracts to flip open the label cover, and then the label stripping pick-and-place two-axis servo mechanism drives the label stripping pick-and-place suction head to remove the label from the liquid storage tank, and then the label stripping cover opening air clamp is released to close the label cover again, completing the label removal process. After the label removal is completed, the liquid storage tank is put back to the liquid storage tank storage system for standby.

At this time, if all the extraction sample liquid is taken, the corresponding colorimetric tube is grabbed from the colorimetric tube storage system 48 by the extraction clamping manipulator 46 and placed at the liquid discharge device. After the liquid discharge device pours the extraction sample liquid in the liquid storage tank 1 into the colorimetric tube, it is put back into the colorimetric tube storage system 48; and if a quantitative extraction sample liquid is to be taken, the extraction sample liquid is first injected into the transfer liquid receiving mechanism 45, and then the extraction clamping manipulator 46 grabs the corresponding colorimetric tube from the colorimetric tube storage system 48, and the extraction sample liquid of the corresponding specification is drawn from the transfer liquid receiving mechanism 45 by the quantitative liquid taking mechanism 47 and injected into the corresponding colorimetric tube, and then put back into the colorimetric tube storage system 48 after completion;
