[0029] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-11 The utility model provides a technical solution: an azo pretreatment workstation, comprising an automatic liquid adding module 1, an ultrasonic water bath module 2, an automatic powder adding, aspiration and filtration module 4, and a transport composite robot 5, wherein the transport composite robot 5 is provided with two transport composite robots 5, each of which is a transport composite robot with automatic navigation and a positioning module;

[0031] The automatic liquid adding module 1 includes a first cover opening mechanism 10 for automatic opening and a liquid adding mechanism 11 for automatic liquid addition. The first cover opening mechanism 10 includes a cover opening clamp 101 and a cover opening rotary cylinder 102 connected to the cover opening clamp 101. The liquid adding mechanism 11 includes a liquid injection head 110 and a liquid injection drive cylinder 111 connected to the liquid injection head 110. The automatic liquid adding module 1 includes a first frame 12, on which a positioning communication QR code is provided. The positioning module on the transport compound robot 5 includes a camera. The positioning communication QR code can be mutually identified and corresponded with the camera in the positioning module on the transport compound robot 5. The camera can be used to identify the positioning communication QR code to calculate the deviation position. The ultrasonic water bath module 2 and The automatic powder adding, liquid absorption and filtration modules 4 are all provided with corresponding positioning communication QR codes, so that the handling compound robot 5 can be positioned and moved accurately at each module station. The first frame 12 is provided with a first conveyor belt 120 for conveying the test bottles to be added with liquid, and the first frame 12 is provided with a rotating disk 121. The rotating disk 121 is provided with a plurality of placement slots 122 for placing the test bottles. The handling compound robot 5 is provided with a handling clamp for clamping the test bottles into the placement slots 122. The first opening mechanism 10 includes a support plate 103 fixedly mounted on the first frame 12, and a first guide rail 104 is provided on the support plate 103. The opening rotary cylinder 102 slides with the first guide rail 104, and the opening clamp 101 is also provided with a clamping cylinder 1 connected thereto. 05, the cover opening rotary cylinder 102 is connected to the clamping cylinder 105 by a transmission rod 106, and the support plate 103 is also provided with a positioning cylinder 107 and a positioning clamping claw 108 which is transmission-connected to the positioning cylinder 107 and is used to position the test bottle. The liquid injection drive cylinder 111 is fixedly installed on the support plate 103. When the buffer solution needs to be added for the first time, several test bottles are first placed on the rack, and then the rack carrying the test bottles is placed on the first conveyor belt 120. The first conveyor belt 120 transports the rack carrying the test bottles to the other end of the first conveyor belt 120, and then the transport compound robot 5 uses the transport clamping claw to clamp the test bottle on the rack and places the clamped test bottle into the placement slot 122 on the rotating disk 121. The transporting clamping claws are clamped or opened by the cylinder drive, and the placement slots 122 are provided with a number of equal distances on the rotating disk 121, so as to improve the liquid adding efficiency. The rotating disk 121 rotates to rotate the test bottle located in the placement slot 122 to the position corresponding to the first opening mechanism 10. At this time, the positioning cylinder 107 drives the positioning clamping claws 108 to be pushed out. The positioning clamping claws 108 are driven by the cylinder to clamp and position the test bottle located in the placement slot 122. Then, the opening rotation cylinder 102 located on the support plate 103 descends along the first guide rail 104, so that the opening clamping claws 101 can just clamp the bottle cap of the test bottle. The opening rotation cylinder 102 can slide up and down along the first guide rail 104 and is driven to rise and fall by the cylinder. This technology is existing technology and will not be described in detail here.After the bottle cap is unscrewed, the open cover rotating cylinder 102 drives the transmission rod 106 to rotate, thereby driving the open cover clamping claw 101 to rotate, thereby unscrewing the bottle cap. After unscrewing, the open cover rotating cylinder 102 rises along the first guide rail 104 again. At this time, the liquid injection driving cylinder 111 drives the liquid injection head 110 to be pushed above the bottle mouth of the test bottle. The liquid injection pipe is connected to the liquid injection head 110, so that the extract is injected into the test bottle by the liquid injection head 110, thereby completing the first liquid addition process. When the liquid addition is completed, the open cover rotating cylinder 102 descends again to achieve reversal, and the bottle cap is unscrewed by the open cover clamping claw 101. Tightly screwed onto the test bottle, since the rotating disk 121 is provided with several placement slots 122 at equal intervals, to improve liquid addition efficiency, two first opening mechanisms 10 and a liquid addition mechanism 11 are provided on the first rack 12, allowing for simultaneous initial liquid addition. When liquid addition is complete, the rotating disk 121 rotates again, and the transport robot 5 then picks up the liquid-filled test bottle and places it on the rack. By repeating this operation, the entire rack of test bottles is filled with liquid. After the initial liquid addition is complete, the transport robot 5 then moves the entire rack to the ultrasonic water bath module 2, where the test bottles are shaken to thoroughly mix the sample and buffer solution in the test bottle.

[0032] The liquid adding mechanism 11 includes a liquid injection head 110 and a liquid injection driving cylinder 111 which is transmission-connected to the liquid injection head 110. The automatic powder adding liquid suction and filtering module 4 includes a powder adding mechanism 40 for adding powder into the bottle and a liquid suction mechanism 41 for filtering and sucking liquid after adding powder. The powder adding mechanism 40 includes a powder tank 400 and a lower powder block 401 located at the open end of the powder tank 400. The liquid suction mechanism 41 includes a liquid suction syringe 410 and a liquid suction cylinder 411 which is transmission-connected to the liquid suction syringe 410. The automatic powder adding liquid suction and filtering module 4 includes a second frame 42. A second conveying belt 420 is provided inside the second frame 42. A loading cylinder is provided at one end of the second conveying belt 420. A loading plate is provided at the driving end of the loading cylinder. A loading plate is provided on the surface of the second frame 42 corresponding to the loading plate. The powder adding mechanism 40 includes a support column 402 provided on the surface of the second frame 42, a pushing cylinder 403 is provided on the upper end of the support column 402, and the pushing cylinder 403 is provided with a pushing plate 404 connected thereto in a transmission manner, and the lower powder block 401 is provided on the upper surface of the pushing plate 404, and a chute 405 is provided in the middle of the lower powder block 401, and a powder leakage hole 406 communicating with the chute 405 is provided on the upper surface of the lower powder block 401, and a powder adding hole 407 communicating with the chute 405 is provided on the lower surface of the lower powder block 401, and the powder leakage hole 406 and the powder adding hole 407 are staggered up and down, and the opening end of the powder tank 400 is limited in cooperation with the powder leakage hole 406, and a powder pushing and unloading cylinder 408 is further provided on the pushing plate 404, and a powder pushing block 409 is provided at the driving end of the powder pushing and unloading cylinder 408. 409 is limited and slidably matched with the slide 405. The second frame 42 is also provided with a bottle moving mechanism 43 for clamping and moving the test bottle. The bottle moving mechanism 43 includes a second guide rail 430 provided on the surface of the second frame 42. The second guide rail 430 is provided with a bottle moving clamp 431 that slides with it. The surface of the second frame 42 is also provided with a second opening mechanism 44 at one end of the bottle moving mechanism 43. The liquid suction mechanism 41 includes a gantry slide rail 412 provided on the surface of the second frame 42. The liquid suction cylinder 411 slides with the gantry slide rail 412. The gantry slide rail 412 is also provided with a third opening mechanism 413 that slides with it. The surface of the second frame 42 is also provided with a filtering mechanism 45. The filtering mechanism 45 includes a lifting cylinder 450 fixedly mounted on the surface of the second frame 42. The driving end of the lifting cylinder 450 is provided with a filter plate 451 connected thereto by transmission. After the liquid addition is completed, the entire rack carrying the test bottles is placed on the second conveyor belt 420. There is an opening on the side of the second frame 42 for conveniently placing the rack on the second conveyor belt 420. The second conveyor belt 420 transports the rack forward until it is transported to the loading plate. Then the loading cylinder drives the loading plate to rise, thereby lifting the rack from the loading port 421. The test bottle is then clamped and taken out of the rack by the bottle moving claw 431. The bottle moving claw 431 then slides on the second guide rail 430 to the bottom of the second opening mechanism 44. The second opening mechanism 44 rotates the cap of the test bottle that needs to be added with powder to open the cap.Then the bottle moving clamp 431 pushes the opened test bottle to the bottom of the powder adding hole 407. At this time, the powder pushing and unloading cylinder 408 drives the powder pushing block 409 to slide in the chute 405, thereby pushing the powder falling from the powder tank 400 into the chute 405 to the powder adding hole 407 and falling into the test bottle. When powder needs to be added, the pushing cylinder 403 can push the pushing plate 404 forward, thereby driving the lower powder block 401 to the top of the test bottle, and the powder tank 400 is placed upside down so that the bottle mouth and the powder leakage hole 406 are limited and matched. At this time, the powder in the powder tank 400 falls into the chute 405 from the powder leakage hole 406 and falls into the test bottle. Two air pipes are provided near the bottle mouth of the powder tank 400, which can slowly blow hot air into the bottle to prevent the powder in the powder tank 400 from getting wet. When the powder falls into the chute 405, since the powder adding hole 407 and the powder leakage hole 406 are arranged in an up-down staggered manner, the powder pushing and unloading cylinder 408 drives the powder pushing block 409 to slide in the chute 405. At this time, the powder pushing block 409 can naturally push the powder in the chute 405 to the powder adding hole 407, and then the powder falls from the powder adding hole 407 and falls into the test bottle, thereby completing the powder adding process. In order to improve the powder adding efficiency, the powder adding mechanism 40 is arranged on the second frame There are two on 42. When the powder is added, the bottle moving clamp 431 moves the test bottle to the bottom of the second opening mechanism 44 again, and the second opening mechanism 44 seals the test bottle. Then the bottle moving mechanism 43 moves the test bottle to the bottom of the liquid suction mechanism 41. At this time, the third opening mechanism 413 opens the bottle cap on the test bottle, and the lifting cylinder 450 drives the filter plate 451 to descend, so that the filter plate 451 extends into the test bottle. Since there are several filter holes on the filter plate 451, the solution in the test bottle can be filtered at this time. Then the liquid suction cylinder 411 drives the liquid suction syringe 410 to extend into the test bottle. The filtered solution is aspirated and then transferred to another test bottle for testing. The second and third opening mechanisms 44 and 413 are identical to the first opening mechanism 10, so the specific opening principles will not be described here. The gantry slide 412 is divided into an X-axis slide and a Y-axis slide, allowing the aspiration mechanism 41 to be flexibly moved to the desired aspiration position. When all the test bottles on the rack have been filtered through the powder-added aspiration process, the loading cylinder drives the loading plate down, allowing the rack containing the test bottles to land on the second conveyor belt 420, which then transports the unloaded material.

[0033] The working principle of the present invention is as follows: an automatic liquid adding module 1, an ultrasonic water bath module 2, and an automatic powder adding, aspiration and filtration module 4 are respectively provided, and the automatic liquid adding module 1 can automatically complete the opening and liquid adding of the test bottle, and the automatic powder adding, aspiration and filtration module 4 can automatically add the corresponding extraction reagent, so that the entire azo pretreatment process can be fully automated, thereby greatly improving the corresponding work efficiency.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
