Description

Technical Field

[0001] This utility model relates to the field of filtration, and in particular to an automated purification and filtration pretreatment device. Background Technology

[0002] Before liquid sample analysis, an automated purification and filtration pretreatment device is required to remove solid impurities from the liquid. Some existing automated purification and filtration pretreatment devices include a pipetting assembly on the base, equipped with a pipette. The pipette moves to the source liquid bottle placement area to draw up the raw liquid, then moves to the filter placement area. A needle filter can be inserted into the end of the pipette, which then moves along with the needle filter to the collection bottle placement area, aligns with the collection bottle, and dispenses the liquid. After passing through the needle filter, the liquid flows into the collection bottle, which is then capped by the operator. The pipette can then remove the inserted needle filter and clean and dry it for the next filtration separation process. However, these automated purification and filtration pretreatment devices require manual intervention in the collection bottle capping process, resulting in insufficient safety and automation. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automated purification and filtration pretreatment device that eliminates the need for manual intervention in the bottle capping process, thereby improving safety and automation.

[0004] An automated purification and filtration pretreatment device according to an embodiment of the present invention includes a base, a bottle opening assembly, a bottle transfer assembly, and a liquid transfer assembly. The machine base is provided with a bulk solution bottle placement area, a filter placement area, a collection bottle placement area, and a dispensing area. A bottle opening assembly is disposed on the machine base, comprising a bottle gripping mechanism and a rotation driver. The bottle gripping mechanism is rotatably disposed on the machine base and located in the dispensing area, and the rotation driver drives the bottle gripping mechanism to rotate. A bottle transfer assembly is disposed on the machine base, comprising a cap gripping mechanism and a cap transfer driving mechanism. The cap gripping mechanism is movably disposed on the machine base and can move between the collection bottle placement area and the dispensing area. The cap gripping mechanism can move closer to or further away from the bottle gripping mechanism, and the cap transfer driving mechanism drives the cap gripping mechanism to move. A pipetting assembly is disposed on the machine base, comprising a pipette and a pipetting driving mechanism. The pipette is movably disposed on the machine base and can move between the bulk solution bottle placement area, the filter placement area, and the dispensing area, and the pipetting driving mechanism drives the pipette to move.

[0005] The automated purification and filtration pretreatment device according to the embodiments of this utility model has at least the following beneficial effects: When the device is working, the pipetting drive mechanism of the pipetting assembly drives the pipetting needle to move to the raw liquid bottle placement area to draw the raw liquid. Then, the pipetting needle moves to the filter placement area to insert the needle filter. After that, the pipetting needle drives the needle filter to move to the injection area. During this period, the cap transfer drive mechanism of the bottle transfer assembly drives the cap gripping mechanism to move to the collection bottle placement area. The cap gripping mechanism grips the cap of the collection bottle, drives the entire collection bottle to move to the injection area, and places the bottle body of the collection bottle into the bottle body gripping mechanism. The drive then rotates the bottle gripping mechanism, while the cap gripping mechanism holds the cap and moves it away from the bottle gripping mechanism, allowing the bottle body and cap to rotate relative to each other and separate. The pipette then injects the filtered liquid into the collection bottle. The cap gripping mechanism then moves the cap closer to the bottle gripping mechanism, and with the rotation of the bottle gripping mechanism, the cap of the collection bottle is tightened. The bottle transfer assembly then moves the collection bottle back to the collection bottle placement area. No manual intervention is required in the cap tightening process, reducing the possibility of workers coming into contact with the filtered liquid, thereby improving safety and automation.

[0034] Reference Figures 1 to 3 This is an automated purification and filtration pretreatment device according to an embodiment of the present invention, comprising a base 100, a bottle opening assembly 200, a bottle transfer assembly 300, and a liquid transfer assembly 400. The base 100 is provided with a raw liquid bottle placement area, a filter placement area, a collection bottle placement area, and a liquid injection area. The bottle opening assembly 200 is disposed on the base 100 and includes a bottle gripping mechanism 210 and a rotation driver. The bottle gripping mechanism 210 is rotatably disposed on the base 100 and located in the liquid injection area. The rotation driver is used to drive the bottle gripping mechanism 210 to rotate. The bottle transfer assembly 300 is disposed on the base 100 and includes a bottle cap gripping mechanism 310 and a cap transfer driving mechanism 320. The bottle cap gripping mechanism 310 is movably disposed. The device is mounted on the base 100 and can move between the collection bottle placement area and the dispensing area. The cap gripping mechanism 310 can move closer to or further away from the bottle body gripping mechanism 210. The cap removal driving mechanism 320 is used to drive the cap gripping mechanism 310 to move. The pipetting assembly 400 is mounted on the base 100 and is equipped with a pipetting needle 410 and a pipetting driving mechanism 420. The pipetting needle 410 is movably mounted on the base 100 and can move between the original liquid bottle placement area, the filter placement area and the dispensing area. The pipetting driving mechanism 420 is used to drive the pipetting needle 410 to move.

[0035] During operation, the pipetting drive mechanism 420 of the pipetting assembly 400 drives the pipetting needle 410 to move to the stock solution bottle placement area to draw the raw material liquid. Then, the pipetting needle 410 moves to the filter placement area to insert the needle filter. Afterward, the pipetting needle 410 moves the needle filter to the dispensing area. Meanwhile, the cap transfer drive mechanism 320 of the bottle transfer assembly 300 drives the cap gripping mechanism 310 to move to the collection bottle placement area. The cap gripping mechanism 310 grips the cap of the collection bottle, moving the entire collection bottle to the dispensing area and placing the bottle body into the bottle body gripping mechanism 210. Then, the drive mechanism rotates to drive the bottle body gripping mechanism. The bottle cap gripping mechanism 310 rotates while the bottle cap gripping mechanism 310 holds the bottle cap and moves away from the bottle body gripping mechanism 210, allowing the bottle body and bottle cap to rotate relative to each other and separate. Then, the pipette needle 410 injects the filtered liquid into the body of the collection bottle. After that, the bottle cap gripping mechanism 310 moves the bottle cap closer to the bottle body gripping mechanism 210. With the rotation of the bottle body gripping mechanism 210, the bottle cap of the collection bottle is tightened. Then, the bottle transfer assembly 300 moves the collection bottle back to the collection bottle placement area. No manual intervention is required in the process of tightening the cap of the collection bottle, reducing the possibility of workers coming into contact with the filtered liquid, thereby improving safety and automation.

[0036] Specifically, the automated purification and filtration pretreatment device in this embodiment provides the physical basis for the automated unscrewing and screwing on of the collection bottle.

[0037] In this embodiment, the bottle gripping mechanism 210 includes two bottle gripping arms 211 and a bottle gripping driver 212. The bottle gripping arms 211 are connected to the bottle gripping driver 212, which is rotatably mounted on the base 100. The bottle gripping driver 212 drives the two bottle gripping arms 211 to move closer or further apart, forming a bottle gripping position between them. The bottle body of the collection bottle is placed between the two bottle gripping arms 211. The bottle gripping driver 212 can drive the two bottle gripping arms 211 to move closer together to grip and fix the bottle body. When the bottle gripping mechanism 210 rotates, the bottle gripping arms 211 drive the bottle body of the collection bottle to rotate, simulating an opening action. When it is necessary to remove the collection bottle, the bottle gripping driver 212 can drive the two bottle gripping arms 211 to move further apart to release the bottle body. The structure is simple and easy to implement.

[0038] Specifically, the bottle gripper 212 can adopt a structure such as a pneumatic gripper or an electric gripper, and the bottle gripping arm 211 is the finger part of the gripper. The bottle gripping mechanism 210 may include a rotating base, the bottle gripper 212 is connected to the rotating base, and the rotating base is rotatably connected to the base 100, thereby enabling the bottle gripper 212 to rotate relative to the base 100; or the bottle gripper 212 can be directly pivotally connected to the base 100.

[0039] It is conceivable that in other embodiments, the bottle gripping mechanism 210 may also include a rotating seat and a suction cup. The rotating seat is pivotally connected to the base 100, and the suction cup is disposed on the rotating seat. The bottle body of the collection bottle is gripped and fixed by the suction cup. When the rotating seat rotates, the bottle body can be rotated by the suction cup to simulate the process of rotating to open the cap.

[0040] In this embodiment, the bottle cap gripping mechanism 310 includes two bottle cap gripping arms 311 and a bottle cap gripping driver 312. The bottle cap gripping arms 311 are connected to the bottle cap gripping driver 312, which is disposed in the cap shifting drive mechanism 320. The bottle cap gripping driver 312 drives the two bottle cap gripping arms 311 to move closer or further apart, forming a bottle cap gripping position between the two bottle cap gripping arms 311. The bottle cap of the collection bottle is placed between the two bottle cap gripping arms 311. The bottle cap gripping driver 312 can drive the two bottle cap gripping arms 311 to move closer together, gripping the bottle cap through the bottle cap gripping arms 311 to fix the bottle cap of the collection bottle and drive the collection bottle as a whole to move. When the bottle body gripping mechanism 210 rotates, the relative rotation between the bottle cap and the bottle body can be realized, realizing the screw cap on the collection bottle. The structure is simple and easy to implement. When it is necessary to release the bottle cap, the bottle cap clamping driver 312 drives the two bottle cap clamping arms 311 to move away from each other, so as to release the bottle cap of the collection bottle.

[0041] Specifically, the bottle cap gripping actuator 312 can adopt a structure such as a pneumatic gripper or an electric gripper, and the bottle cap gripping arm 311 is the finger part of the gripper. It is conceivable that in some other embodiments, the bottle cap gripping mechanism 310 can adopt a suction cup, which is attached to the bottle cap of the collection bottle to grip the bottle cap of the collection bottle.

[0042] In this embodiment, the cap-moving drive mechanism 320 includes a first cap-moving frame 321, a first cap-moving driver, a second cap-moving frame 322, a second cap-moving driver, a third cap-moving frame 323, and a third cap-moving driver 324. The first cap-moving frame 321 is slidably disposed on the base 100 in the left-right direction. The first cap-moving driver is disposed on the base 100 and is used to drive the first cap-moving frame 321 to move left and right. The second cap-moving frame 322 is slidably disposed on the first cap-moving frame 321 in the front-back direction. The second cap-moving driver is disposed on the first cap-moving frame 321 and is used to drive the second cap-moving frame 322 to move front and back. The third cap-moving frame 323 is slidably disposed on the second cap-moving frame 322 in the up-down direction. The third cap-moving driver 324 is disposed on the second cap-moving frame 322 and is used to drive the third cap-moving frame 323 to move up and down. The bottle cap gripping mechanism 310 is connected to the third cap-moving frame 323. The above-described cap-moving drive mechanism 320 can realize three-axis three-dimensional movement of the bottle cap gripping mechanism. It has a relatively simple structure and is easy to implement.

[0043] Specifically, the first cover-moving frame 321 can slide approximately relative to the base 100° via a slide rail and slider structure or a guide post and guide sleeve structure. The first cover-moving driver can use, for example, a motor and a synchronous belt to drive the first cover-moving frame 321 to move left and right, or a linear drive structure such as a linear motor or an electric cylinder. The second cover-moving frame 322 can move back and forth relative to the first cover-moving frame 321 via a slide rail and slider structure or a guide post and guide sleeve structure. The second cover-moving driver can use, for example, a motor and a synchronous belt to drive the second cover-moving frame 322 to move back and forth, or a linear drive structure such as a linear motor or an electric cylinder. The third cover-moving frame 323 can move up and down relative to the second cover-moving frame 322 via a slide rail and slider structure or a guide post and guide sleeve structure. The third cover-moving driver 324 can use, for example, a motor and a lead screw and lead screw nut to drive the third cover-moving frame 323 to rise and fall, or a linear drive structure such as an electric cylinder or a linear motor.

[0044] It is conceivable that in other embodiments, the cap-moving drive mechanism 320 may adopt a structure such as a three-axis robotic arm to drive the cap-grabbing mechanism 310 to move.

[0045] In this embodiment, the specific structure of the pipetting drive mechanism 420 is the same as that of the capping drive mechanism 320. The pipetting drive mechanism 420 is connected to the pipetting needle 410 and can drive the pipetting needle 410 to move along three axes. It is conceivable that in other embodiments, the pipetting drive mechanism 420 may also adopt a structure such as a three-axis robotic arm to drive the pipetting needle 410 to move.

[0046] In this embodiment, a filter recovery mechanism 500 is also included. The filter recovery mechanism 500 is disposed on the base 100. The filter recovery mechanism 500 includes a separation baffle 510 and a collection box 520. The separation baffle 510 is located above the collection box 520. The lower side of the separation baffle 510 forms a filter stop surface. The pipette 410 is arranged in the vertical direction and can move up and down relative to the base 100.

[0047] After the pipette 410 completes filtration, when it is necessary to remove the needle filter, the pipette 410 moves the needle filter so that it is located below the separation baffle 510. Then, the pipette 410 moves upward, and the separation baffle 510 blocks the movement of the needle filter, causing it to detach from the pipette 410. The needle filter then falls into the collection box 520 for recycling. This filter recycling structure utilizes the movement of the pipette 410 itself to remove the needle filter; the structure is relatively simple and easy to implement.

[0048] It is conceivable that in other embodiments, the filter recovery mechanism 500 may also have other structures. For example, the filter recovery mechanism 500 includes a pneumatic gripper and a collection box 520. When the pipette 410 moves the needle filter to the vicinity of the pneumatic gripper, the pneumatic gripper grabs and fixes the needle filter. Then the pipette 410 moves, causing the needle filter to separate from the pipette 410. Then the pneumatic gripper releases the needle filter, allowing the needle filter to fall into the collection box 520.

[0049] Specifically, the bottom wall of the collection box 520 is inclined, and the end of the collection box 520 that is closer to the separation baffle 510 in the horizontal direction is higher than the end of the collection box 520 that is farther away from the separation baffle 510 in the horizontal direction. This makes it less likely for the needle filter to accumulate below the separation baffle 510 after it falls into the collection box 520, so that the collection box 520 can collect more waste needle filters.

[0050] Specifically, the base 100 is provided with a support frame 120, which includes an upper support plate 121, a support column 122, and a lower frame strip 123. The upper support plate 121 and the lower frame strip 123 are both arranged in the horizontal direction. The lower frame strip 123 is arranged around the outer periphery of the collection box 520. The upper support plate 121 is located above the lower frame strip 123. The upper support plate 121 is connected to the lower frame strip 123 through the support column 122. The filter placement area and the collection bottle placement area are both located on the upper side of the upper support plate 121. The collection box 520 is located on the lower side of the upper support plate 121. The distance between the upper side of the collection box 520 and the upper support plate 121 is greater than the height of the lower frame strip 123. The collection box 520 is surrounded by a lower frame strip 123, which makes it difficult for the collection box 520 to be accidentally pulled. When it is necessary to remove the collection box 520, first raise the collection box 520 above the lower frame strip 123, and then the collection box 520 can be removed.

[0051] In this embodiment, the separating baffle 510 is provided with a needle clearance groove 511, which extends vertically through the separating baffle 510. The opening of the needle clearance groove 511 is located at one end of the separating baffle 510 in the horizontal direction, and the groove wall of the needle clearance groove 511 is provided with an elastic layer 512. The pipette 410 can move horizontally into the needle clearance groove 511 from the opening, increasing the contact area between the lower side of the separating baffle 510 and the needle filter, thus more stably and reliably peeling off the needle filter. Furthermore, the elastic layer 512 on the groove wall of the needle clearance groove 511 reduces the risk of damage to the pipette 410 when it accidentally collides with the separating baffle 510, thereby improving the durability of the pipette 410.

[0052] Specifically, the elastic layer 512 can be a sponge layer, which is adhered to the groove wall of the needle relief groove 511; or the elastic layer 512 can be a rubber layer or a silicone layer that is adhered to the groove wall of the needle relief groove 511.

[0053] In this embodiment, an air pump is also included. The air pump is mounted on the base 100 and has an air intake port. The base 100 has an air extraction hole 110 located beside the raw material bottle placement area, and the air intake port is connected to the air extraction hole 110. In some cases, the raw material liquid may contain certain volatile toxic substances. In this case, the air pump can be activated. The air intake port of the air pump is connected to the air extraction hole 110 to extract air from the vicinity of the raw material bottle placement area, thereby reducing health hazards to workers. The extracted air can be purified by a purification device before being discharged into the outside air, reducing pollution to the external environment.

[0054] In this embodiment, a raw material tray 600 is also included. The raw material tray 600 is detachably mounted on the base 100 and located in the raw material bottle placement area. The raw material tray 600 is provided with a plurality of raw material bottle receiving holes 601, with the openings of the raw material bottle receiving holes 601 facing upwards. The raw material tray 600 has a plurality of raw material bottle receiving holes 601, and bottles containing raw material liquid can be inserted into the raw material bottle receiving holes 601, which facilitates batch placement of raw material liquid; the raw material tray is detachable, which facilitates the removal of the raw material tray for batch loading and unloading.

[0055] Specifically, the base 100 is provided with a first positioning groove, the raw liquid tray 600 is placed on the base 100, and the lower end of the raw liquid tray 600 is embedded in the first positioning groove, realizing the detachable installation of the raw liquid tray 600. It can be understood that in some other embodiments, the base 100 may be provided with a positioning post, and the raw liquid tray 600 may be provided with a positioning hole. The raw liquid tray 600 is inserted into the positioning post and the positioning hole to realize the detachable installation and positioning of the raw liquid tray 600.

[0056] Specifically, the concentrate tray 600 includes an upper frame 610 and a lower support plate 620. The upper frame 610 has a through hole along its vertical direction and is detachably connected to the upper side of the lower support plate 620. The lower support plate 620 covers the lower end of the through hole and defines a concentrate bottle receiving hole 601. When a large number of bottles are inserted into the concentrate tray 600, the upper frame 610 can be removed upwards, allowing the bottles to rest on the lower support plate 620. Then, the lower support plate 620 can be tilted to quickly empty the bottles from the concentrate tray 600. The upper frame 610 can then be reinstalled. Specifically, the upper frame 610 and the lower support plate 620 can be detachably installed and positioned by means such as snap-fit ​​or plug-in.

[0057] In this embodiment, a filter tray 700 is also included. The filter tray 700 is detachably mounted on the base 100 and located in the filter placement area. The filter tray 700 is provided with multiple filter insertion holes 701, with the openings of the filter insertion holes 701 facing upwards. The filter tray 700 has multiple filter insertion holes 701, and the lower end of the needle filter can be inserted into the filter insertion hole 701 for positioning, facilitating the insertion of the pipette 410 with the upper end of the needle filter. The filter tray 700 is detachable, allowing for easy removal of the filter tray 700 for batch loading and unloading.

[0058] Specifically, the base 100 is provided with a second positioning groove, the filter tray 700 is placed directly on the base 100, and the lower end of the filter tray 700 is embedded in the second positioning groove for positioning. It is conceivable that in other embodiments, the base 100 may be provided with positioning posts, and the filter tray 700 may be provided with positioning holes. The filter tray 700 can be detachably installed and positioned by the insertion and engagement of the positioning posts and positioning holes.

[0059] In this embodiment, a bottle collection tray 800 is also included. The bottle collection tray 800 is detachably mounted on the base 100 and located in the bottle collection area. The bottle collection tray 800 is provided with a plurality of bottle receiving holes 801, with the openings of the bottle receiving holes 801 facing upwards. The bottle collection tray 800 has a plurality of bottle receiving holes 801, which can be inserted to receive bottles, facilitating the batch placement of bottles. The bottle collection tray 800 is detachable, making it easy to remove the bottle collection tray 800 for batch loading and unloading.
