Description

Technical Field

[0001] The invention relates to the technical field of automated detection, and in particular to an automated subpackaging and extraction system for air sampling carbon tubes. Background Art

[0002] Air quality testing is an important part of environmental testing. Carbon tube is a product used for air testing, such as Figure 1 As shown, the carbon tube 1 includes a hollow glass tube 11 with air holes 111 at both ends and a sealing sleeve 12 sleeved on both ends of the hollow glass tube 11, a partition cotton core 13 is provided at about 1 / 3 of the position in the hollow glass tube 11, and a marking line 112 is provided on the outer wall of the hollow glass tube 11 at a position corresponding to the partition cotton core 13. The partition cotton core 13 divides the space in the hollow glass tube 11 into a first chamber and a second chamber, and the first chamber and the second chamber are both filled with carbon particles 14.

[0003] When in use, in the environment to be tested, remove the sealing sleeves 12 at both ends, and start to evacuate air through one end. The air enters the hollow glass tube 11 from the air hole 111 at the other end and is then discharged. The gases to be tested, such as formaldehyde and sulfur monoxide in the air, are adsorbed by the carbon particles 14. After the air extraction is completed, the sealing sleeves 12 are put on the two ends of the hollow glass tube 11 and sealed. In the laboratory, use a tool to cut the ring two or three times along the marked line 112, break the hollow glass tube 11 along the marked line 112, and then use tweezers to take out the separating cotton core 13. Add the carbon particles 14 in the two parts of the hollow glass tube 11 into two experimental bottles respectively, and add the corresponding amount of absorption liquid respectively. The gas absorbed in the carbon particles 14 is dissolved by the absorption liquid, and the parameters of the gas to be tested can be tested on the corresponding experimental equipment, thereby achieving the purpose of air detection.

[0004] However, since the operation process of manually cutting the hollow glass tube and then breaking it is relatively inconvenient, the detection efficiency is low, and the carbon particles are easily spilled when breaking or pouring, affecting the test results. At the same time, the amount of absorption liquid added manually is difficult to control, which will reduce the accuracy of subsequent test results. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an air sampling carbon tube automatic packaging and extraction system, which simplifies the manual operation process and improves the test efficiency and test accuracy.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] An air sampling carbon tube automatic packaging and extraction system, comprising:

[0008] frame;

[0009] A carbon tube loading device carried by the frame, the carbon tube loading device comprising: a loading conveyor belt for conveying the first loading trays forward one by one, a first full tray bin arranged on one side of the loading conveyor belt, a first empty tray bin arranged on the other side of the loading conveyor belt, and a carbon tube loading manipulator for grabbing the carbon tubes one by one, wherein the first loading tray is loaded with a plurality of carbon tubes;

[0011] A transfer device carried on the frame, the transfer device comprising: a transfer drive mechanism, a transfer rotary cylinder connected to the power output end of the transfer drive mechanism, a carbon tube transfer air clamp carried on the power output end of the transfer rotary cylinder for clamping the broken carbon tubes from the first breaking clamping mechanism and the second breaking clamping mechanism, a bottle-settling mechanism for arranging and outputting two groups of transfer bottles side by side, and a bottle-taking and clamping air clamp carried on the power output end of the transfer rotary cylinder and corresponding to the carbon tube transfer air clamp for receiving the transfer bottle, the bottle mouth of the transfer bottle being aligned with the carbon tube when on the bottle-taking and clamping air clamp, and a carbon tube waste collection bucket is provided on the frame;

[0012] A liquid adding and transferring device carried on the frame, the liquid adding and transferring device comprising: a liquid adding driving mechanism, a liquid adding clamping mechanism connected to the power output end of the liquid adding driving mechanism for receiving and clamping a transfer bottle into which carbon particles are poured, a plurality of automatic liquid adding mechanisms for adding the same or different absorption liquids, and a liquid adding and sealing mechanism for screwing a bottle cap on the transfer bottle after liquid addition;

[0013] A stationary device carried by the frame, the stationary device comprising: a stationary clamping mechanism for clamping the transfer bottle after the capping is completed, a stationary conveying line for transferring the second loading tray, a stationary storage bin for storing the second loading tray, and a stationary fetching and delivering mechanism for grabbing the second loading tray to flow between the stationary conveying line and the stationary storage bin, wherein the second loading tray is provided with a plurality of receiving openings for placing the transfer bottle;

[0014] The pipetting device carried on the frame comprises: a rotating rack for placing a second material loading tray that has been placed still, a first pipetting clamping air clamp for receiving and clamping a transfer bottle that has been placed still, a pipetting capping mechanism for screwing the bottle cap of the transfer bottle clamped by the first pipetting clamping air clamp, a bottle feeding mechanism for transporting detection bottles one by one, a second pipetting clamping air clamp for receiving and clamping the detection bottles, a pipetting driving mechanism for driving the first pipetting clamping air clamp and the second pipetting clamping air clamp to move back and forth, a quantitative liquid taking mechanism for drawing a quantitative absorption liquid from the pipetting bottle clamped by the first pipetting clamping air clamp and transferring it to the detection bottle clamped by the second pipetting clamping air clamp, and a pipetting capping mechanism for screwing the bottle cap on the detection bottle after the pipetting is completed; and,

[0015] A material receiving and storing device is carried on the frame and is used for storing the capped testing bottles.

[0016] To implement the above technical solution, when working, the carbon tubes after the gas sampling are manually arranged on the first loading tray and stored in the first full tray bin, and the first loading tray is transported to the loading station one by one by the feeding conveyor belt, and the carbon tube loading robot is used to take the carbon tubes from the first loading tray, and then the camera is used to shoot the carbon tubes, and the position of the marking line is identified. The carbon tube loading robot will insert the carbon tube into the cutting mechanism until the marking line is aligned with the tool, and the cutting mechanism will cut the carbon tube at the marking line for two or three weeks, and then the carbon tube loading robot will transfer the cut carbon tube to the first breaking clamping mechanism, and the first breaking clamping mechanism and the carbon tube will be cut. The tube feeding manipulator clamps the upper and lower parts of the carbon tube at the same time, applies force to the carbon tube through the push-breaking mechanism to break the carbon tube from the cut position, and makes the separating cotton core located in the upper part of the carbon tube. At this time, the upper part of the carbon tube is separated from the lower part, and due to the blocking effect of the separating cotton core, the carbon particles in the upper part will not leak out. Then the carbon tube feeding manipulator transfers the upper part of the carbon tube to the second breaking clamping mechanism. The second breaking clamping mechanism clamps the upper part of the carbon tube and then turns it 180 degrees to make its opening face upward. Then the separating cotton core is clamped out by the clamping mechanism and put into the carbon tube waste collection bucket, thus completing the carbon tube breaking process.

[0017] Then, the transfer drive mechanism drives the carbon tube transfer air clamp to move to the position corresponding to the first breaking clamping mechanism and the second breaking clamping mechanism. After the carbon tube transfer air clamp clamps the upper and lower parts of the carbon tube respectively, the transfer drive mechanism transfers the bottle taking clamping air clamp to the exit of the whole bottle mechanism. After the whole bottle mechanism arranges and arranges the transfer bottles, they fall into the bottle taking clamping air clamp from the exit and are clamped. At this time, the bottle mouth of the transfer bottle is docked with the opening of the carbon tube. The carbon tube transfer air clamp and the bottle taking clamping air clamp are driven by the transfer rotary cylinder to rotate 180° at the same time, so that the carbon particles in the carbon tube are dumped into the transfer bottle, that is, the carbon particle transfer process is completed;

[0018] After the carbon particles are dumped, the transfer drive mechanism drives the bottle-taking clamping air clamp to align with the liquid-adding clamping mechanism. After the liquid-adding clamping mechanism clamps the transfer bottle, the carbon tube transfer air clamp and the bottle-taking clamping air clamp are reset to re-clamp the next group of carbon tubes and the transfer bottle, and the empty carbon tubes are placed in the carbon tube waste collection bucket. The liquid-adding drive mechanism drives the liquid-adding clamping mechanism to carry the transfer bottle to the corresponding automatic liquid-adding mechanism position, and the automatic liquid-adding mechanism adds the set amount of corresponding absorption liquid into the transfer bottle, and then moves to the liquid-adding capping mechanism to screw the bottle cap on the transfer bottle, thus completing the liquid-adding process;

[0019] After the liquid addition is completed, the static clamping mechanism takes the transfer bottle out of the liquid adding clamping mechanism and places it on the second loading tray. The liquid adding clamping mechanism resets and clamps the next group of transfer bottles. After the second loading tray is full of transfer bottles, the static conveyor line conveys the second loading tray to the static storage bin, and the static pick-up and delivery mechanism puts the second loading tray into the static storage bin. At the same time, a new empty second loading tray is taken and placed on the static conveyor line and transferred to the static clamping mechanism. The transfer bottle is left to stand in the static storage bin for two hours for the absorption and extraction process, so as to facilitate subsequent sampling and testing.

[0020] After the static standing is completed, the second loading tray is grabbed by the static picking and feeding mechanism and placed on the transfer rack, and the pipetting and capping mechanism grabs a transfer bottle from the second loading tray and places it on the first pipetting clamping air clamp. After the first pipetting clamping air clamp clamps the transfer bottle, the pipetting and capping mechanism unscrews the bottle cap of the transfer bottle, and at the same time, an empty detection bottle is placed on the second pipetting clamping air clamp through the bottle feeding mechanism, and then the pipetting drive mechanism drives the first pipetting clamping air clamp and the second pipetting clamping air clamp to move to the transfer bottle and is located directly under the quantitative liquid taking mechanism. The quantitative liquid taking mechanism first draws a set amount of absorption liquid from the transfer bottle, and then the pipetting drive mechanism drives the first pipetting clamping air clamp and the second pipetting clamping air clamp to move to the detection bottle and is located directly under the quantitative liquid taking mechanism. The quantitative liquid taking mechanism then injects the drawn absorption liquid into the detection bottle to complete the pipetting process;

[0021] The test bottle after the transfer is taken out by the transfer capping mechanism for capping, and after capping, it is collected and stored by the material storage device for testing, while the transfer bottle is moved to the transfer capping mechanism again to tighten the bottle cap again, and the transfer bottle is put back to the corresponding position on the second loading tray by the transfer capping mechanism. After all the transfer bottles on the second loading tray are transferred, the second loading tray is taken and placed in the static storage bin by the static picking and sending mechanism again, and then manually placed in other storage rooms for one month for subsequent re-testing;

[0022] The present invention can realize the steps of automated carbon tube cutting, carbon tube breaking, carbon particle transfer, quantitative filling of absorption liquid, standing, sample liquid packaging and the like, greatly simplifying the manual operation process, and only one staff member is needed to place and take the plate, thereby reducing labor costs, and the phenomenon of carbon particles not easily spilling during the processing process is not likely to occur, and the absorption liquid filling amount is more controllable, which improves the accuracy of subsequent test results, and greatly improves work efficiency at the same time, and the automation system has strong sustainable working ability, and the daily processing capacity can be increased several times to meet the needs of large-scale testing, and the space required is smaller.

[0023] As a preferred solution of the present invention, the carbon tube feeding robot comprises: a carbon tube feeding three-axis servo mechanism, a feeding rotary cylinder carried on the power output end of the carbon tube feeding three-axis servo mechanism, and a feeding air clamp carried on the power output shaft of the feeding rotary cylinder.

[0024] To implement the above technical solution, the three-axis servo mechanism for carbon tube feeding drives the feeding rotary cylinder to move, the feeding air clamp clamps one end of the carbon tube, and the feeding rotary cylinder drives the feeding air clamp to rotate and adjust the direction of the carbon tube to meet the placement requirements of the carbon tubes at different workstations.

[0025] As a preferred solution of the present invention, the cutting mechanism comprises: a cutting frame, a circular cutting disc rotatably mounted on the cutting frame, a glass cutter arranged on the circular cutting disc, and a cutting drive mechanism for driving the circular cutting disc to rotate, wherein the circular cutting disc is provided with a through hole for inserting the carbon tube;

[0026] The push-folding mechanism comprises: a push-folding cylinder aligned with the first breaking and clamping mechanism, and a push-folding block fixed to the piston rod of the push-folding cylinder;

[0027] The second breaking and clamping mechanism comprises: a reversing rotary cylinder arranged at one side of the first breaking and clamping mechanism, and a breaking and clamping air clamp fixed to the power output end of the reversing rotary cylinder;

[0028] The core removal mechanism includes: a clamping drive cylinder arranged on one side of the second breaking clamping mechanism, a clamping air clamp fixed to the piston rod of the clamping drive cylinder, and clamping forceps arranged on the clamping part of the clamping air clamp.

[0029] To implement the above technical solution, after the camera recognizes the marking line of the carbon tube, the carbon tube feeding robot inserts the carbon tube into the opening of the circular cutting disc until the marking line is aligned with the glass cutter, and then the cutting drive mechanism drives the circular cutting disc to rotate, so that the glass cutter cuts around the marking line for two or three weeks. The cutting position must ensure that the separating cotton core can be retained in the upper part of the carbon tube. After the cutting is completed, the carbon tube feeding robot transfers the carbon tube to the first breaking clamping mechanism, and the feeding rotary cylinder drives the feeding air clamp to rotate so that the carbon tube is in a vertical state. Then the feeding air clamp and the first breaking clamping mechanism simultaneously clamp the upper and lower parts of the carbon tube. The carbon tube is divided and the position of the marking line is made to correspond to the push-fold block, and the push-fold block is driven by the push-fold cylinder to apply force to the carbon tube. Since the marking line has been cut, it is easy to break after being subjected to force; then the carbon tube feeding manipulator transfers the upper part of the carbon tube to the second breaking clamping mechanism, and the breaking clamping air clamp clamps the upper part of the carbon tube, and then the reversing rotary cylinder rotates the upper part of the carbon tube 180° to make the separating cotton core face upward, and then the clamping driving cylinder drives the clamping air clamp to move, and then the clamping air clamp drives the clamping tweezers to clamp out the separating cotton core and transfer it to the carbon tube waste collection bucket, thus completing the carbon tube breaking process.

[0030] As a preferred embodiment of the present invention, the bottle-filling mechanism includes: a bottle-filling vibration plate, a bottle-filling track connected to the discharge port of the bottle-filling vibration plate and having two discharge channels, a bottle-turning assembly arranged on one side of the bottle-filling track for turning the transfer bottle to a state with the bottle mouth facing downward, and a bottle-dropping assembly connected to the discharge channel.

[0031] As a preferred solution of the present invention, the bottle turning assembly includes: a turning frame carried by the frame, a lifting cylinder fixed to the turning frame, a turning cylinder fixed to the power output end of the lifting cylinder, a turning air clamp fixed to the piston rod of the turning cylinder, a positioning cylinder fixed to the turning frame, and a positioning clamp fixed to the piston rod of the positioning cylinder and located directly below the turning air clamp for inserting into the whole bottle track to position the transfer bottle, the whole bottle track is provided with a notch adapted to the chuck of the turning air clamp and a positioning socket adapted to the positioning clamp; The bottle dropping assembly includes: a bottle supporting plate fixed at the outlet of the whole bottle track, a bottle moving block slidably assembled on the bottle supporting plate, and a bottle moving cylinder for driving the bottle moving block to reciprocate, the bottle moving block is provided with a bottle placing port adapted to the discharge channel, the bottle supporting plate is provided with a bottle dropping port offset from the discharge channel, the bottle moving block can slide to the bottle placing port and correspond to the bottle dropping port, the bottle picking clamping air clamp can be moved by the transfer driving mechanism to be aligned with the bottle dropping port, and the clamping head of the bottle picking clamping air clamp is provided with a limiting step for limiting the falling distance of the transferred bottle.

[0032] To implement the above technical solution, the whole-bottle vibration plate arranges the transfer bottles into rows and conveys them forward. Due to the limitation of the transfer bottle structure, it is difficult to stably arrange the transfer bottles in a state where the bottle mouths face downward in the whole-bottle vibration plate. Therefore, the transfer bottles output from the whole-bottle vibration plate are usually in a state where the bottle mouths face upward. After being arranged on the whole-bottle vibration plate, the transfer bottles enter the whole-bottle track. When passing through the bottle turning assembly, the positioning cylinder first drives the positioning clamp to insert into the positioning socket to limit the movement of the corresponding transfer bottle, and then the lifting cylinder drives the flipping cylinder to move downward. After the transfer bottle is clamped by the flipping air clamp, the flipping cylinder moves upward again and rotates the flipping air clamp 180°, and then the transfer bottle is put back into the whole-bottle track. The transfer bottle is then moved to the position where the bottle is placed on the transfer block, and the positioning clamp is separated from the whole bottle track. The transfer bottle that has been turned over can continue to be transported forward and enter the two discharge channels respectively. Then the transfer bottle enters the bottle placing port of the bottle transfer block. After the transfer driving mechanism moves the bottle picking clamping air clamp to a position aligned with the bottle dropping port, the bottle transfer cylinder drives the bottle transfer block to move until the bottle placing port is aligned with the bottle dropping port. The transfer bottle can fall from the bottle dropping port into the chuck of the bottle picking clamping air clamp and is restricted by the positioning step so as to be exactly connected with the carbon tube. After the bottle picking clamping air clamp clamps the transfer bottle, the carbon tube transfer air clamp and the bottle picking clamping air clamp can be driven by the transfer rotating cylinder to rotate 180° at the same time, so that the carbon particles in the carbon tube are dumped into the transfer bottle.

[0033] As a preferred solution of the present invention, the liquid adding clamping mechanism comprises: a liquid adding mobile frame connected to the power output end of the liquid adding driving mechanism, a liquid adding reversing cylinder fixed to the liquid adding mobile frame, a rotating disk connected to the piston rod of the liquid adding reversing cylinder, and two groups of liquid adding air clamps fixed to the rotating disk and arranged side by side for clamping the transfer bottle for adding carbon particles;

[0034] The automatic liquid adding mechanism comprises: a liquid adding frame carried by the frame, a mounting shell being fixed on the liquid adding frame; a liquid injection mechanism carried by the liquid adding frame; and a liquid transfer control mechanism carried by the mounting shell for controlling the liquid injection mechanism to take liquid or inject liquid;

[0035] The injection mechanism comprises: a pipette clamped on the liquid adding stand, a conversion joint sealedly connected to the injection head of the pipette, a liquid collection tube connected to the conversion joint and used to extend into the reagent bottle to draw reagent, and a liquid injection head connected to the conversion joint and used to connect with the transfer bottle, the liquid collection tube is connected to a first one-way valve, and the liquid injection head is connected to a second one-way valve;

[0036] The pipetting control mechanism comprises: a movable control block slidably mounted on the mounting housing and connected to the piston rod of the pipette, and a servo drive assembly for controlling the reciprocating lifting and lowering movement of the movable control block;

[0037] The liquid adding and capping mechanism comprises: a liquid adding and capping vibration plate for arranging, conveying and transferring bottle caps, a liquid adding and capping two-axis servo mechanism carried on the frame, a liquid adding and screwing motor carried on the power output end of the liquid adding and capping two-axis servo mechanism, and a liquid adding elastic chuck fixed to the power output shaft of the liquid adding and screwing motor for clamping the bottle caps.

[0038] To implement the above technical solution, after the carbon particles are dumped, the transfer drive mechanism drives the bottle-taking clamping air clamp to align with the liquid-adding air clamp. After the liquid-adding air clamp clamps the transfer bottle, the rotating disk is driven to rotate 180° by the liquid-adding reversing cylinder. Then the liquid-adding drive mechanism drives the liquid-adding clamping mechanism to carry the transfer bottle to the corresponding automatic liquid-adding mechanism position. The pipetting control mechanism drives the active control block to move upward through the servo drive assembly according to the set pipetting amount, so that the active control block drives the piston rod of the pipette to be pulled out to extract a corresponding amount of reagent. Then the servo drive assembly drives the active control block to move downward again, driving the piston rod of the pipette to be pressed downward, thereby pressing the extracted reagent out of the injection head and injecting it into the transfer bottle; then the two-axis servo mechanism of liquid-adding and capping drives the liquid-adding screwing motor to move to the discharge port of the liquid-adding and capping vibration disk, and the liquid-adding elastic chuck takes a sorted bottle cap and puts it on the pipetting bottle, and then the liquid-adding elastic chuck is driven by the liquid-adding screwing motor to rotate to tighten the bottle cap, thus completing the liquid-adding process.

[0047] To implement the above technical solution, the three-axis servo mechanism for pipetting and capping drives the pipetting and screwing motor to move to the transfer rack, and the corresponding transfer bottle is taken by the pipetting elastic clamp and transferred to the first pipetting clamping air clamp. After the first pipetting clamping air clamp clamps the transfer bottle, the pipetting and screwing motor drives the pipetting elastic clamp to screw out the bottle cap of the transfer bottle. At the same time, the bottle feeding vibration plate arranges the test bottles and then transports them forward. The three-axis servo mechanism for feeding the bottle drives the bottle feeding air clamp to clamp an empty test bottle and place it on the second pipetting clamping air clamp. Then the pipetting drive mechanism drives the first pipetting clamping air clamp to move to the quantitative liquid taking mechanism.

[0048] The gun tip vibration plate arranges the pipette heads and then puts them into the transfer port of the gun tip moving block, and the supporting step supports the pipette heads. Then the gun tip transfer cylinder drives the gun tip moving block to move to the bottom of the pipette gun. The two-axis servo mechanism for taking liquid drives the pipette gun to move so that the pipette head is covered on the head of the pipette gun and then inserted into the transfer bottle. The first pressing cylinder is extended and the pipette button of the pipette gun is pressed once to take out a certain amount of sample liquid. Then the pipette driving mechanism drives the second pipette clamping air clamp to move to the quantitative liquid taking mechanism. The pipette gun is inserted into the detection bottle. The first pressing cylinder is extended and the pipette button of the pipette gun is pressed once again to inject the sample liquid into the detection bottle.

[0049] Then the three-axis servo mechanism for liquid transfer and capping drives the liquid transfer and capping motor to move to the discharge port of the liquid transfer and capping vibration plate, and takes a bottle cap through the elastic capping chuck and tightens it on the test bottle, and then the material receiving and storage device collects it. At the same time, the two-axis servo mechanism for liquid collection drives the liquid transfer gun to move above the liquid transfer waste collection bucket, and the second pressing cylinder is extended to press the tip push button of the liquid transfer gun once to disengage the liquid transfer head, and then a new liquid transfer head can be taken;

[0050] After the test bottle is taken away by the material receiving and storage device, the pipetting drive mechanism drives the first pipetting clamping air clamp to move back to the pipetting capping mechanism again, and the pipetting screwing motor drives the pipetting elastic clamp to rotate and tighten the bottle cap on the transfer bottle again, and the transfer bottle is taken back to the original position of the second loading tray by the pipetting capping three-axis servo mechanism, and the next pipetting process can be carried out.

[0052] To implement the above technical solution, the receiving robot clamps the test bottle after pipetting and places it on the third loading tray. After the third loading tray is full, the receiving conveyor belt transfers the third loading tray to the second full tray bin, and the first empty tray bin releases an empty third loading tray again.

[0078] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0079] Example

[0080] An automatic packaging and extraction system for air sampling carbon tubes, such as Figures 2 to 12 As shown, it includes: a frame 2; a carbon tube loading device 3 carried on the frame 2; a carbon tube breaking device 4 carried on the frame 2; a transfer device 5 carried on the frame 2; a liquid adding and transferring device 6 carried on the frame 2; a stationary device 7 carried on the frame 2; a liquid transfer device 8 carried on the frame 2; and a material receiving and storing device 9 carried on the frame 2 for storing the capped test bottles.

[0081] Specifically, the carbon tube loading device 3 includes: a loading conveyor belt 31 for conveying the first loading tray 35 forward one by one, a first full tray bin 32 arranged on one side of the loading conveyor belt 31, a first empty tray bin 33 arranged on the other side of the loading conveyor belt 31, and a carbon tube loading robot 34 for grabbing the carbon tubes one by one. The first loading tray 35 is loaded with a plurality of carbon tubes.

[0082] Among them, the feeding conveyor belt 31 can adopt a belt structure, a chain structure, etc., and a corresponding lifting structure is provided in the first full tray bin 32 and the first empty tray bin 33 to control the lifting and moving of the first loading tray 35, so as to realize the release of the full first loading tray 35 and the stacking of the empty first loading tray 35. The lifting structure can adopt the existing servo lifting mechanism for the loading machine, which will not be described in detail here; Figure 4 As shown, the carbon loading robot includes: a carbon tube loading three-axis servo mechanism 341, a loading rotary cylinder 342 carried on the power output end of the carbon tube loading three-axis servo mechanism 341, and a loading air clamp 343 carried on the power output shaft of the loading rotary cylinder 342. The carbon tube loading three-axis servo mechanism 341 drives the loading rotary cylinder 342 to move, and the loading air clamp 343 clamps one end of the carbon tube, and the loading rotary cylinder 342 drives the loading air clamp 343 to rotate and adjust the direction of the carbon tube to meet the placement requirements of the carbon tubes at different workstations.

[0083] like Figure 5 As shown, the carbon tube breaking device 4 includes: a camera 41 for identifying the marking line of the carbon tube grasped by the carbon tube feeding robot 34, a cutting mechanism 42 for ring cutting the carbon tube at the marking line, a first breaking clamping mechanism 43 for clamping the lower part of the carbon tube, a pushing and breaking mechanism 44 for breaking the carbon tube after ring cutting and allowing the separating cotton core to remain on the upper part of the carbon tube, a second breaking clamping mechanism 45 for clamping and rotating the upper part of the carbon tube, and a coring mechanism for clamping the separating cotton core.

[0084] Among them, the cutting mechanism 42 includes: a cutting frame 421, a circular cutting blade disc 422 rotatably assembled on the cutting frame 421, a glass cutter 423 arranged on the circular cutting blade disc 422, and a cutting drive mechanism 424 for driving the circular cutting blade disc 422 to rotate. The circular cutting blade disc 422 is provided with a through hole 425 for the carbon tube to be plugged in. The cutting drive mechanism 424 can adopt a servo drive mechanism such as a belt drive mechanism, a gear drive mechanism, a sprocket drive mechanism, etc. The glass cutter 423 can be driven by a micro-cylinder to fit or detach from the carbon tube.

[0085] The first breaking clamping mechanism 43 is an air clamp, and the pushing and folding mechanism 44 includes: a pushing and folding cylinder 441 aligned with the first breaking clamping mechanism 43, and a pushing and folding block 442 fixed to the piston rod of the pushing and folding cylinder 441, the pushing and folding cylinder 441 is fixed on the frame 2, and when the carbon tube is clamped on the first breaking clamping mechanism 43, the pushing and folding block 442 is aligned with the marking line of the carbon tube.

[0086] The second breaking and clamping mechanism 45 includes: a reversing rotary cylinder 451 arranged on one side of the first breaking and clamping mechanism 43, and a breaking and clamping air clamp 452 fixed to the power output end of the reversing rotary cylinder 451. The reversing rotary cylinder 451 is a rotary air cylinder. In other embodiments, a rotary electric cylinder or a servo motor or other rotary driving structure can also be used.

[0087] The coring mechanism includes: a clamping drive cylinder 461 arranged on one side of the second breaking clamping mechanism 45, a clamping air clamp 462 fixed to the piston rod of the clamping drive cylinder 461, and a clamping forceps 463 arranged on the clamping part of the clamping air clamp 462. The clamping drive cylinder 461 is arranged in the vertical direction and is used to adjust the clamping position of the clamping forceps 463 to avoid interference with the process of clamping the upper part of the carbon tube to the breaking clamping air clamp 452. In some embodiments, the clamping drive cylinder 461 can be replaced by a two-axis or three-axis servo robot.

[0088] After the camera 41 recognizes the marking line of the carbon tube, the carbon tube feeding manipulator 34 inserts the carbon tube into the opening 425 of the circular cutting knife disk 422 until the marking line is aligned with the glass cutter 423, and then the cutting drive mechanism 424 drives the circular cutting knife disk 422 to rotate, so that the glass cutter 423 cuts around the marking line for two or three weeks. The cutting position must ensure that the separating cotton core can be retained in the upper half of the carbon tube. After the cutting is completed, the carbon tube feeding manipulator 34 transfers the carbon tube to the first breaking clamping mechanism 43, and the feeding rotary cylinder 342 drives the feeding air clamp 343 to rotate to make the carbon tube in a vertical state, and then the feeding air clamp 343 and the first breaking clamping mechanism 43 clamp the upper and lower parts of the carbon tube at the same time. And make the position of the marking line correspond to the push-fold block 442, and drive the push-fold block 442 to apply force to the carbon tube through the push-fold cylinder 441. Since the marking line has been cut, it is easy to break after being subjected to force; then the carbon tube loading robot 34 transfers the upper part of the carbon tube to the second breaking clamping mechanism 45, and the breaking clamping air clamp 452 clamps the upper part of the carbon tube, and then the reversing rotating cylinder 451 rotates the upper part of the carbon tube 180° to make the separating cotton core face upward, and then the clamping driving cylinder 461 drives the clamping air clamp 462 to move, and then the clamping air clamp 462 drives the clamping tweezers 463 to clamp out the separating cotton core and transfer it into the carbon tube waste collection bucket 21, thus completing the carbon tube breaking process.

[0089] like Figure 6As shown, the transfer device 5 includes: a transfer drive mechanism 51, a transfer rotary cylinder 52 connected to the power output end of the transfer drive mechanism 51, a carbon tube transfer air clamp 53 carried by the power output end of the transfer rotary cylinder 52 for clamping the broken carbon tubes from the first breaking clamping mechanism 43 and the second breaking clamping mechanism 45, a bottle assembly mechanism 54 for arranging and outputting two groups of transfer bottles side by side, and a bottle taking and clamping air clamp 55 carried by the power output end of the transfer rotary cylinder 52 and corresponding to the carbon tube transfer air clamp 53 for receiving the transfer bottle, the bottle mouth of the transfer bottle is aligned with the carbon tube when on the bottle taking and clamping air clamp 55, and a carbon tube waste collecting bucket 21 is provided on the frame 2.

[0090] The transfer drive mechanism 51 can adopt a belt mechanism or a screw mechanism, which is used to drive the rod transfer rotary cylinder 52 to move back and forth. The transfer rotary cylinder 52, the carbon tube transfer air clamp 53 and the bottle clamping air clamp 55 are all arranged in two groups dependent on each other, so that the upper and lower parts of the carbon tube can be clamped synchronously, and two groups of transfer bottles can be clamped accordingly. The distance between the two groups of transfer rotary cylinders 52 is at least the size of two transfer bottle heights, and the two groups of transfer rotary cylinders 52 rotate relative to each other, so that no interference will occur during the pouring transfer process.

[0091] The bottle-filling mechanism 54 includes: a bottle-filling vibration plate 541, a bottle-filling track 542 connected to the discharge port of the bottle-filling vibration plate 541 and having two discharge channels 543, a bottle-turning assembly 544 arranged on one side of the bottle-filling track 542 for turning the transfer bottle to a state with the bottle mouth facing downward, and a bottle-dropping assembly 545 connected to the discharge channel 543.

[0092] Among them, the bottle turning assembly 544 includes: a turning frame 5441 carried by the frame 2, a lifting cylinder 5442 fixed to the turning frame 5441, a turning cylinder 5443 fixed to the power output end of the lifting cylinder 5442, a turning air clamp 5444 fixed to the piston rod of the turning cylinder 5443, a positioning cylinder 5445 fixed to the turning frame 5441, and a piston rod fixed to the positioning cylinder 5445 and located directly below the turning air clamp 5444 for inserting into the whole bottle track 542 to position the transfer bottle. A positioning clamp 5446 is provided on the whole bottle track 542 for matching with the clamp head of the turning air clamp 5444 and a positioning socket 5422 for matching with the positioning clamp 5446. A photoelectric sensor or a camera can usually be provided at the slot 5421 to detect whether the transfer bottle has moved into place.

[0093] The bottle dropping assembly 545 includes: a bottle supporting plate 5451 fixed at the exit of the whole bottle track 542, a bottle moving block 5452 slidably assembled on the bottle supporting plate 5451, and a bottle moving cylinder 5453 for driving the bottle moving block 5452 to reciprocate. The bottle moving cylinder 5453 can be fixed on the bottle supporting plate 5451, and the bottle moving block 5452 is provided with a bottle placing opening 5454 adapted to the discharge channel 543. The bottle supporting plate 5451 is provided with a bottle dropping opening offset from the discharge channel 543. The bottle moving block 5452 can slide to the bottle placing opening 5454 to correspond to the bottle dropping opening. The bottle picking and clamping air clamp 55 can be moved by the transfer driving mechanism 51 to be aligned with the bottle dropping opening. The clamping head of the bottle picking and clamping air clamp 55 is provided with a limiting step for limiting the falling distance of the transferred bottle.

[0094] The whole bottle vibration plate 541 arranges the transfer bottles into a row and transports them forward. Due to the limitation of the transfer bottle structure, it is difficult to stably arrange the transfer bottles in a state where the bottle mouths face downward in the whole bottle vibration plate 541. Therefore, the transfer bottles output from the whole bottle vibration plate 541 are usually in a state where the bottle mouths face upward. After being arranged by the whole bottle vibration plate 541, the transfer bottles enter the whole bottle track 542. When passing through the bottle turning assembly 544, the positioning cylinder 5445 first drives the positioning clamping plate 5446 to insert into the positioning socket 542. 2, the corresponding transfer bottle is restricted to move, and then the lifting cylinder 5442 drives the flip cylinder 5443 to move downward. After the transfer bottle is clamped by the flip air clamp 5444, the flip cylinder 5443 moves upward again and rotates the flip air clamp 5444 180°, and then the transfer bottle is put back on the whole bottle track 542, and the positioning clamp 5446 is separated from the whole bottle track 542. The flipped transfer bottle can continue to be transported forward and enter the two discharge channels 543 respectively, and then the transfer bottle enters the transfer bottle After the transfer drive mechanism 51 transfers the bottle picking clamping air clamp 55 to a position aligned with the bottle dropping opening, the bottle moving cylinder 5453 drives the bottle moving block 5452 to move to the bottle placing opening 5454 aligned with the bottle dropping opening, and the transfer bottle can fall from the bottle dropping opening into the chuck of the bottle picking clamping air clamp 55 and just contact with the carbon tube due to the restriction of the positioning step. After the bottle picking clamping air clamp 55 clamps the transfer bottle, the carbon tube transfer air clamp 5453 can be driven by the transfer rotating cylinder 52 to move. 3 and the bottle-taking air clamp 55 are rotated 180° at the same time, so that the carbon particles in the carbon tube are dumped into the transfer bottle. At the same time, a vibrator can be set on the clamp head of the carbon tube transfer air clamp 53, so that the carbon particles in the carbon tube are dumped more thoroughly, and a code sprayer can be set on one side of the transfer drive mechanism 51, and a code scanner is set on the frame 2. When the carbon tube is loaded, the two-dimensional code on the carbon tube is scanned by the code scanner to read and enter the information, and the identification code corresponding to the two-dimensional code of the carbon tube is sprayed on the transfer bottle by the code sprayer.

[0095] like Figure 6 and Figure 7As shown, the liquid adding moving device includes: a liquid adding driving mechanism 61, a liquid adding clamping mechanism 62 connected to the power output end of the liquid adding driving mechanism 61 for receiving and clamping a transfer bottle into which carbon particles are poured, a plurality of automatic liquid adding mechanisms 63 for adding the same or different absorption liquids, and a liquid adding capping mechanism 64 for screwing the bottle cap on the transfer bottle after liquid addition.

[0096] The liquid adding drive mechanism 61 can adopt a belt mechanism or a screw mechanism, and the liquid adding clamping mechanism 62 includes: a liquid adding mobile frame 621 connected to the power output end of the liquid adding drive mechanism 61, a liquid adding reversing cylinder 622 fixed to the liquid adding mobile frame 621, a rotating disk 623 connected to the piston rod of the liquid adding reversing cylinder 622, and two groups of liquid adding air clamps 624 fixed to the rotating disk 623 and arranged side by side for clamping the transfer bottle for adding carbon particles. The liquid adding reversing cylinder 622 can optionally use a rotating cylinder.

[0097] like Figure 8 and Fig. 9 As shown, the automatic liquid adding mechanism 63 includes: a liquid adding frame 631, on which a mounting shell is fixed; a liquid transfer mechanism 632 carried by the liquid adding frame 631; and a liquid transfer control mechanism 633 carried by the mounting frame for controlling the liquid transfer mechanism 632 to take or inject liquid.

[0098] Specifically, the pipetting mechanism 632 includes: a pipette 6321 mounted on the liquid adding rack 631, a conversion joint 6322 sealedly connected to the injection head of the pipette 6321, a liquid collection tube 6323 connected to the conversion joint 6322 for extending into the reagent bottle to draw the reagent, and an injection head 6324 connected to the conversion joint 6322 for injecting the reagent into the experimental container, a first one-way valve 6325 is connected to the liquid collection tube 6323, and a second one-way valve 6326 is connected to the injection head 6324, so that the reagent can be accurately injected into the experimental container.

[0099] The pipetting control mechanism 633 includes: a movable control block 6331 slidably assembled on the mounting shell and connected to the piston rod of the pipette 6321, and a servo drive assembly 6332 for controlling the reciprocating lifting and lowering movement of the movable control block 6331. A clamping sleeve 6333 is fixed on the movable control block 6331, and a clamping protrusion 63211 is provided on the piston rod of the pipette 6321. The interior of the clamping sleeve 6333 is provided with a limiting protrusion 63331 that cooperates with the clamping protrusion 63211, so that the connection between the clamping sleeve 6333 and the piston rod of the pipette 6321 is more stably and firmly.

[0100] At the same time, a connecting cap 6327 for threaded connection with a reagent bottle is also clamped at the bottom of the conversion joint 6322, so as to connect and fix with the reagent bottle for liquid extraction, and a clamping support 6312 with an opening on one side is provided on the liquid adding rack 631, and a positioning convex ring 63221 is provided on the outer wall of the conversion joint 6322, and a positioning step 6313 engaged with the positioning convex ring 63221 is provided on the clamping support 6312, and the open end of the clamping support 6312 is detachably connected with a pressing block 6314 that presses against the conversion joint 6322, so that the pipetting mechanism 632 can be stably clamped on the liquid adding rack 631.

[0101] The servo drive assembly 6332 is selected from the following structures for use alone or in combination: a servo screw assembly or a servo electric cylinder. In this embodiment, the servo drive mechanism adopts a servo screw assembly, and the servo screw assembly includes: a servo motor fixed to the mounting housing, and a driving screw fixed to the power output shaft of the servo motor and rotatably connected to the mounting housing. The driving screw is threadedly connected to the movable control block 6331. The driving screw is driven to rotate by the servo motor, and a threaded transmission can be formed between the driving screw and the movable control block 6331 to achieve precise liquid extraction and injection.

[0102] At the same time, in order to limit the movable stroke of the movable control block 6331, an upper limit switch 6316 and a lower limit switch 6317 are provided on the mounting shell, and a detection block cooperating with the upper limit switch 6316 and the lower limit switch 6317 is provided on the movable control block 6331. When the detection block contacts the upper limit switch 6316 or the lower limit switch 6317, the servo drive assembly 6332 stops running, thereby limiting the operating limit position of the movable control block 6331 to prevent damage to the pipette 6321 caused by excessive moving stroke.

[0103] In this embodiment, a PLC controller is also provided on the liquid adding rack 631, which is connected to the controller of the servo drive component 6332 through the PLC controller, so as to realize precise control of the servo drive component 6332. Correspondingly, the PLC controller can also be connected to human-computer interaction devices such as a touch screen, keyboard, and mouse, so as to set the liquid taking amount for quantitative liquid taking.

[0104] Furthermore, a corrugated sealing band 6315 is provided on one side of the installation shell facing the transfer mechanism 632, and the installation shell can be sealed by the corrugated sealing band 6315, thereby improving the safety during use.

[0105] like Figure 7As shown, the liquid adding and capping mechanism 64 includes: a liquid adding and capping vibration plate 641 for arranging, conveying and transferring bottle caps, a liquid adding and capping two-axis servo mechanism 642 carried on the frame 2, a liquid adding and screwing motor 643 carried on the power output end of the liquid adding and capping two-axis servo mechanism 642, and a liquid adding and screwing elastic chuck 644 fixed to the power output shaft of the liquid adding and screwing motor 643 for clamping the bottle caps. The liquid adding elastic chuck 644 is made of plastic material, and usually a plurality of deformation grooves can be opened on the liquid adding elastic chuck 644 to enable elastic deformation to clamp the bottle caps.

[0106] After the carbon particles are poured, the transfer drive mechanism 51 drives the bottle-taking clamping air clamp 55 to align with the liquid-adding air clamp 624. After the liquid-adding air clamp 624 clamps the transfer bottle, it drives the rotating disk 623 to rotate 180° through the liquid-adding reversing cylinder 622. Then the liquid-adding drive mechanism 61 drives the liquid-adding clamping mechanism 62 to carry the transfer bottle to the corresponding position of the automatic liquid-adding mechanism 63. The liquid-pipette control mechanism 633 drives the active control block 6331 to move up through the servo drive assembly 6332 according to the set liquid-pipette amount, so that the active control block 6331 drives the piston rod of the pipette 6321 to be withdrawn outward. The corresponding amount of reagent is extracted, and then the servo drive component 6332 drives the movable control block 6331 to move downward again, driving the piston rod of the pipette 6321 to press down, thereby pressing the extracted reagent out of the injection head 6324 and injecting it into the transfer bottle; then the liquid adding and capping two-axis servo mechanism 642 drives the liquid adding and screwing motor 643 to move to the discharge port of the liquid adding and capping vibration disk 641, and the liquid adding elastic chuck 644 takes a sorted bottle cap and puts it on the pipette bottle, and then the liquid adding and screwing motor 643 drives the liquid adding elastic chuck 644 to rotate to tighten the bottle cap, thus completing the liquid adding process.

[0107] like Fig.10 As shown, the stationary device 7 includes: a stationary clamping mechanism 7146 for clamping the transfer bottle with the screw cap completed, a stationary conveyor line 72 for transferring the second loading tray 75, a stationary storage bin 73 for storing the second loading tray 75, and a stationary picking and delivering mechanism 74 for grabbing the second loading tray 75 and transferring it between the stationary conveyor line 72 and the stationary storage bin 73. The second loading tray 75 is provided with a plurality of receiving openings for placing transfer bottles.

[0108] Specifically, the static clamping mechanism 7146 includes: a static clamping two-axis servo mechanism 711, and two groups of static bottle picking air clamps 712 connected to the power output end of the static clamping two-axis servo mechanism 711 and corresponding to the liquid adding air clamp 624, and the two groups of static bottle picking air clamps 712 correspond to the two groups of liquid adding air clamps 624; the static conveyor line 72 can choose a belt conveyor line or a roller conveyor line, and the static picking and delivering mechanism 74 includes: a static picking and delivering three-axis servo mechanism 741, and a picking and delivering fork plate 742 connected to the power output end of the static picking and delivering three-axis servo mechanism 741. Correspondingly, a recess matched with the picking and delivering fork plate 742 is provided at the bottom of the second loading tray 75 to facilitate the picking and delivering fork plate 742 to fork. The static bottle picking air clamp 712 is driven by the static clamping two-axis servo mechanism 711 to move, and the capped pipette bottles are clamped to the second loading tray 75. After the second loading tray 75 is full of pipette bottles, the three-axis servo mechanism drives the picking and sending fork plate 742 to fork the second loading tray 75 into the static storage bin 73 for static placement.

[0109] like Fig.11 and Fig.12 As shown, the pipetting device 8 includes: a transfer rack 81 for placing the second loading tray 75 that has been placed still, a first pipetting clamping air clamp 82 for receiving and clamping the transfer bottle that has been placed still, a pipetting capping mechanism 83 for screwing the bottle cap of the transfer bottle clamped by the first pipetting clamping air clamp 82, a bottle feeding mechanism 84 for transporting the detection bottles one by one, a second pipetting clamping air clamp 85 for receiving and clamping the detection bottles, a pipetting driving mechanism 86 for driving the first pipetting clamping air clamp 82 and the second pipetting clamping air clamp 85 to move back and forth, a quantitative liquid taking mechanism 87 for drawing a quantitative absorption liquid from the pipetting bottle clamped by the first pipetting clamping air clamp 82 and transferring it to the detection bottle clamped by the second pipetting clamping air clamp 85, and a pipetting capping mechanism 88 for screwing the bottle cap on the detection bottle after the pipetting is completed.

[0110] The transfer rack 81 is arranged at one side of the static storage bin 73 to facilitate the transfer of the transfer bottles loaded in the second loading tray 75. The pipetting and capping mechanism 83 includes: a three-axis pipetting and capping servo mechanism 831 carried by the frame 2, a pipetting and capping motor 832 fixed to the power output end of the three-axis pipetting and capping servo mechanism 831, and a power output shaft fixed to the pipetting and capping motor 832 for clamping the pipetting elastic chuck 833 of the pipetting bottle cap. Similarly, a plurality of deformation grooves can also be provided on the pipetting elastic chuck 833 to elastically deform and clamp the bottle cap of the transfer bottle for transfer. At the same time, a shedding air clamp is fixed on the transverse moving end corresponding to the pipetting and capping motor 832 on the three-axis pipetting and capping servo mechanism 831. The shedding air clamp is used to clamp the transfer bottle after the pipetting is completed. Then the pipetting and capping motor 832 moves up to make the transfer bottle detach from the pipetting elastic chuck 833 so that it can be put back on the second loading tray 75.

[0111] The pipetting drive mechanism 86 is a belt mechanism or a screw mechanism. The first pipetting clamping air clamp 82 and the second pipetting clamping air clamp 85 are fixed to a movable plate at the same time, so that the pipetting drive mechanism 86 can drive both to move simultaneously. The first bottle feeding mechanism 84 includes: a bottle feeding vibration plate 841, a bottle feeding three-axis servo mechanism 842 carried by the frame 2, and a bottle feeding air clamp 843 fixed to the power output end of the bottle feeding three-axis servo mechanism 842.

Similarly, a plurality of deformation grooves are provided on the capping elastic chuck 884 to enable elastic deformation to occur and clamp the caps.

[0115] Correspondingly, a code sprayer may also be provided on one side of the liquid transfer driving mechanism 86 for spraying a two-dimensional code corresponding to the carbon tube two-dimensional code on the detection bottle.

[0116] The three-axis servo mechanism 831 drives the pipetting and screwing motor 832 to move to the transfer rack 81, and the corresponding transfer bottle is taken by the pipetting elastic clamp 833 and transferred to the first pipetting clamping air clamp 82. After the first pipetting clamping air clamp 82 clamps the transfer bottle, the pipetting and screwing motor 832 drives the pipetting elastic clamp 833 to screw out the bottle cap of the transfer bottle. At the same time, the bottle feeding vibration plate 841 arranges the test bottles and transports them forward. The three-axis servo mechanism 842 drives the bottle feeding air clamp 843 to clamp an empty test bottle and place it on the second pipetting clamping air clamp 85. Then the pipetting drive mechanism 86 drives the first pipetting clamping air clamp 82 to move to the quantitative liquid taking mechanism 87.

[0117] The gun tip vibration plate 871 arranges the pipette heads and then puts them into the transfer port 894 of the gun tip moving block 892, and the supporting step supports the pipette heads. Then, the gun tip transfer cylinder 893 drives the gun tip moving block 892 to move to the bottom of the pipette gun 874, and the two-axis servo mechanism 872 drives the pipette gun 874 to move so that the pipette head is covered on the head of the pipette gun 874 and then inserted into the transfer bottle. The first pressing cylinder 875 is extended and pressed to press the pipette button of the pipette gun 874 to take out a certain amount of sample liquid at one time. Then, the pipette drive mechanism 86 drives the second pipette clamping air clamp 85 to move to the quantitative liquid taking mechanism 87, and the pipette gun 874 is inserted into the detection bottle. The first pressing cylinder 875 is extended and pressed to press the pipette button of the pipette gun 874 once again, and the sample liquid can be injected into the detection bottle.

[0118] Then, the three-axis servo mechanism 882 for liquid transfer and capping drives the liquid transfer and capping motor 883 to move to the discharge port of the liquid transfer and capping vibration plate 881, and a bottle cap is put on the detection bottle through the elastic capping chuck 884, and then the bottle cap is collected by the receiving and storing device 9. At the same time, the two-axis servo mechanism 872 for liquid collection drives the liquid transfer gun 874 to move above the liquid transfer waste collection bucket 877, and the second pressing cylinder 876 is extended and pressed to push the tip push button of the liquid transfer gun 874 once to disengage the liquid transfer head, so that the next new liquid transfer head can be put on.

[0119] After the test bottle is taken away by the material receiving and storage device 9, the pipetting drive mechanism 86 drives the first pipetting clamping air clamp 82 to move back to the pipetting capping mechanism 83 again, and the pipetting screwing motor 832 drives the pipetting elastic clamp 833 to rotate and tighten the bottle cap on the transfer bottle again, and the transfer bottle is taken back to the original position of the second loading tray 75 by the pipetting capping three-axis servo mechanism 831, and the next pipetting process can be carried out.

[0120] The material receiving and storage device 9 includes: a material receiving conveyor belt 91 for conveying the third material loading tray forward one by one, a second empty tray bin 92 arranged on one side of the material receiving conveyor belt 91, a second full tray bin 93 arranged on the other side of the material receiving conveyor line, and a material receiving robot 94 for grabbing the test bottles after pipetting one by one from the third material loading tray. The third material loading tray is provided with a plurality of placement holes for placing the test bottles; similarly, corresponding lifting structures are also provided in the second full tray bin 93 and the second empty tray bin 92 to control the lifting and lowering movement of the third material loading tray to realize the release of the empty third material loading tray and the stacking of the full third material loading tray. The lifting structure can adopt the existing servo lifting mechanism for the loading machine, which will not be elaborated here. The material receiving robot 94 can adopt the existing three-axis servo robot.

[0121] The receiving robot 94 picks up the test bottle after the transfer and places it on the third loading tray. After the third loading tray is full, the receiving conveyor belt 91 transfers the third loading tray to the second full tray bin 93, and the first empty tray bin 33 releases an empty third loading tray again.

[0122] During operation, the carbon tubes after the gas sampling are manually arranged on the first loading tray 35 and stored in the first full tray bin 32. The first loading tray 35 is transported to the loading station one by one by the loading conveyor belt 31. The carbon tube loading robot 34 takes the carbon tubes from the first loading tray 35. Then the camera 41 takes a picture of the carbon tubes and identifies the position of the marking line. The carbon tube loading robot 34 inserts the carbon tube into the cutting mechanism 42 until the marking line is aligned with the tool. The cutting mechanism 42 cuts the carbon tubes at the marking line for two or three weeks. Then the carbon tube loading robot 34 transfers the cut carbon tubes to the first breaking clamping mechanism 43. The first breaking clamping mechanism 43 The upper and lower parts of the carbon tube are clamped together with the carbon tube feeding manipulator 34, and the carbon tube is broken from the cut position by the push-breaking mechanism 44, and the separating cotton core is located in the upper part of the carbon tube. At this time, the upper part of the carbon tube is separated from the lower part, and due to the blocking effect of the separating cotton core, the carbon particles in the upper part will not leak out. Then the carbon tube feeding manipulator 34 transfers the upper part of the carbon tube to the second breaking clamping mechanism 45, and the second breaking clamping mechanism 45 clamps the upper part of the carbon tube and then turns it 180 degrees to make its opening face upward, and then the separating cotton core is clamped out by the clamping mechanism 46 and put into the carbon tube waste collecting bucket 21, and the carbon tube breaking process is completed;

[0123] Then the transfer drive mechanism 51 drives the carbon tube transfer air clamp 53 to move to the position corresponding to the first breaking clamp mechanism 43 and the second breaking clamp mechanism 45. After the carbon tube transfer air clamp 53 clamps the upper and lower parts of the carbon tube respectively, the transfer drive mechanism 51 moves the bottle taking clamping air clamp 55 to the exit of the bottle filling mechanism 54. After the bottle filling mechanism 54 arranges and arranges the transfer bottles, they fall into the bottle taking clamping air clamp 55 from the exit and are clamped. At this time, the bottle mouth of the transfer bottle is docked with the opening of the carbon tube. The carbon tube transfer air clamp 53 and the bottle taking clamping air clamp 55 are driven by the transfer rotary cylinder 52 to rotate 180° at the same time, so that the carbon particles in the carbon tube are dumped into the transfer bottle, that is, the carbon particle transfer process is completed;

[0124] After the carbon particles are dumped, the transfer drive mechanism 51 drives the bottle-taking clamping air clamp 55 to align with the liquid-adding clamping mechanism 62. After the liquid-adding clamping mechanism 62 clamps the transfer bottle, the carbon tube transfer air clamp 53 and the bottle-taking clamping air clamp 55 are reset to re-clamp the next group of carbon tubes and the transfer bottle, and the empty carbon tubes are placed in the carbon tube waste collection bucket 21. The liquid-adding drive mechanism 61 then drives the liquid-adding clamping mechanism 62 to carry the transfer bottle to the corresponding position of the automatic liquid-adding mechanism 63, and the automatic liquid-adding mechanism 63 adds the set amount of corresponding absorption liquid into the transfer bottle, and then moves to the liquid-adding capping mechanism 64 to screw the bottle cap on the transfer bottle, thus completing the liquid-adding process.

[0125] After the liquid addition is completed, the static clamping mechanism 7146 takes the transfer bottle out of the liquid adding clamping mechanism 62 and places it on the second loading tray 75. The liquid adding clamping mechanism 62 resets to clamp the next group of transfer bottles. After the second loading tray 75 is full of transfer bottles, the static conveying line 72 conveys the second loading tray 75 to the static storage bin 73, and the static picking and delivering mechanism 74 puts the second loading tray 75 into the static storage bin 73. At the same time, a new empty second loading tray 75 is taken and placed on the static conveying line 72 and transferred to the static clamping mechanism 7146. The transfer bottle is left to stand in the static storage bin 73 for two hours for the absorption and extraction process, so as to facilitate subsequent sampling and testing.

[0126] After the static state is completed, the second loading tray 75 is grabbed by the static picking and feeding mechanism 74 and placed on the transfer rack 81, and the liquid transfer and capping mechanism 83 grabs a transfer bottle from the second loading tray 75 and places it on the first liquid transfer clamping air clamp 82. After the first liquid transfer clamping air clamp 82 clamps the transfer bottle, the liquid transfer and capping mechanism 83 unscrews the bottle cap of the transfer bottle. At the same time, an empty detection bottle is placed on the second liquid transfer clamping air clamp 85 through the bottle feeding mechanism 84, and then the liquid transfer driving mechanism 86 drives the first liquid transfer clamping air clamp 82 and the second liquid transfer clamping air clamp 85 to move to the transfer bottle and is located directly under the quantitative liquid taking mechanism 87. The quantitative liquid taking mechanism 87 first draws a set amount of absorption liquid from the transfer bottle, and then the liquid transfer driving mechanism 86 drives the first liquid transfer clamping air clamp 82 and the second liquid transfer clamping air clamp 85 to move to the detection bottle and is located directly under the quantitative liquid taking mechanism 87. The quantitative liquid taking mechanism 87 then injects the drawn absorption liquid into the detection bottle to complete the liquid transfer process;

[0127] The test bottle after the transfer is taken out by the transfer capping mechanism 88 for capping, and after capping, it is collected and stored by the material storage device for testing, and the transfer bottle is moved to the transfer capping mechanism 83 again to tighten the bottle cap again, and the transfer bottle is put back to the corresponding position on the second loading tray 75 by the transfer capping mechanism 83. After all the transfer bottles on the second loading tray 75 are transferred, the second loading tray 75 is taken and put into the static storage bin 73 by the static fetching mechanism 74, and then manually placed in other storage rooms for one month for subsequent re-testing.

[0128] The present invention can realize the steps of automated carbon tube cutting, carbon tube breaking, carbon particle transfer, quantitative filling of absorption liquid, standing, sample liquid packaging and the like, greatly simplifying the manual operation process, and only one staff member is needed to place and take the plate, thereby reducing labor costs, and the phenomenon of carbon particles not easily spilling during the processing process is not likely to occur, and the absorption liquid filling amount is more controllable, which improves the accuracy of subsequent test results, and greatly improves work efficiency at the same time, and the automation system has strong sustainable working ability, and the daily processing capacity can be increased several times to meet the needs of large-scale testing, and the space required is smaller.
