Description

Technical Field

[0001] The invention belongs to the technical field of enzymology or microbiology devices, and in particular relates to a full-automatic liquid transfer workstation. Background Art

[0002] In microbial culture and subculture, or in metabolite detection or other analysis, a pipetting workstation is often needed. With the help of a pipetting workstation, a quantitative culture medium can be accurately drawn and added to the culture container to provide a stable nutritional environment for microbial growth. Metabolites in microbial fermentation broth can also be extracted for subsequent analysis and detection. The pipetting workstation has a wide range of important applications in the fields of enzymology and microbiology.

[0003] Although the current pipetting workstation has a high degree of automation, and can basically use a robotic arm to replace manual labor for operations such as taking and placing gun tips and transporting culture plates, due to the large consumption of gun tips, the pipetting workstation not only needs to reserve enough space to install gun tip boxes, resulting in a waste of space, but also needs to control the robotic arm to replenish new gun tip boxes after the gun tips are consumed, which is inefficient.

[0004] At present, the patent document with publication number CN115074232A discloses a fully automatic liquid transfer workstation, which adopts the method of stacking gun tip boxes together to form stacked boxes. Although this method increases the preparation amount of gun tip boxes, when the gun tips in the top gun tip box are used up, it is necessary to use a mechanical arm to remove the discarded gun tip box and send it out of the workstation or stack the discarded gun tip box in other cells. In this process, not only does it need to switch the working mode of the mechanical arm, but it also interrupts the original operation of the mechanical arm, making the continuity of the experimental process poor and affecting work efficiency.

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] like Figure 1-Figure 11 As shown, a fully automatic liquid transfer workstation comprises a shell 1, in which a mechanical arm 2 for liquid transfer operation is installed, and in which a bearing component 4, a storage component 5 and a driving component 3 are arranged.

[0041] The bearing assembly 4 is movably installed in the shell 1, the storage assembly 5 is fixedly installed in the shell 1, the bearing assembly 4 can move to a first position and a second position in the shell 1, and the driving assembly 3 is used to drive the bearing assembly 4 to move back and forth between the first position and the second position.

[0042] When the carrying assembly 4 is in the first position, it can cooperate with the robot arm 2. That is to say, the robot arm 2 takes out the gun tip from the carrying assembly 4 at the first position each time. Compared with the existing gun tip boxes scattered in various places, the robot arm 2 needs to plan the path according to the consumption of the gun tip. In this embodiment, the robot arm 2 takes out the gun tip at a fixed point each time, and its path planning is simpler.

[0043] When the carrying component 4 is in the second position, it can cooperate with the storage component 5. That is to say, the storage component 5 is fixedly installed at the second position, and when the carrying component 4 moves to the second position, it corresponds to the position of the storage component 5. The discarded gun tip box 61 on the carrying component 4 is transferred to the storage component 5, and the standby gun tip box 62 on the storage component 5 is transferred to the carrying component 4. In this way, there are always standby gun tip boxes 62 for selection on the carrying component 4, and the reserve of standby gun tip boxes 62 is sufficient to meet the needs of longer experimental cycles. The robot arm 2 does not need to participate in the process of removing the discarded gun tip boxes 61 and placing the standby gun tip boxes 62, so the robot arm 2 does not need to replace the operating part back and forth, which is more efficient and easier to operate.

[0044] More specifically, a carrying bracket 452 is disposed on the carrying component 4 , and the carrying bracket 452 is used to place the ready-to-use gun tip box 62 to cooperate with the robot arm 2 to perform pipetting operations.

[0045] The number of storage components 5 is at least one group, and the storage component 5 is used to store discarded gun tip boxes 61 and standby gun tip boxes 62. The standby gun tip box 62 refers to a gun tip box in which a gun tip to be used is placed, and the discarded gun tip box 61 refers to a gun tip box in which the gun tip is completely taken out. The above-mentioned gun tip boxes all adopt a stacking box method, and a larger number of gun tip boxes can be stored by stacking up and down. At the same time, in order to improve stability, a clamping mechanism such as a clamping groove or a clamping protrusion is also provided at the upper and lower ends of the gun tip box, respectively. Under the action of the clamping groove and the clamping protrusion, the lateral limitation of the adjacent gun tip boxes is achieved to prevent them from tipping over.

[0046] The driving assembly 3 includes a turntable 31, which is rotatably mounted on the inner bottom surface of the housing 1. The housing 1 is provided with an element for driving the turntable 31 to rotate, such as a motor or a hydraulic cylinder, and the bearing assembly 4 is installed at a non-center position of the turntable 31. More specifically, the bearing assembly 4 is installed at a position close to the edge of the turntable 31, and when the turntable 31 rotates, it can drive the bearing assembly 4 to change position. The storage assembly 5 is arranged directly above the turntable 31. More specifically, a through opening is provided in the middle of the turntable 31, and a fixed shaft 32 is provided in the through opening. The lower end of the fixed shaft 32 is fixedly mounted on the inner bottom surface of the housing 1, and one end of the storage assembly 5 is fixedly connected to the housing 1, and the other end is fixedly connected to the fixed shaft 32 to enhance its bearing strength. When the bearing assembly 4 rotates with the turntable 31, it can move directly below the storage assembly 5.

[0047] like Figure 3 As shown, in this embodiment, the number of storage components 5 is three groups, and the three groups of storage components 5 are equidistantly distributed around the center of the turntable 31. The number of supporting brackets 452 is two groups, and the two groups of supporting brackets 452 are symmetrically installed on both sides of the lifting platform 42. The storage component 5 includes a first storage plate 51 and a second storage plate 52, and the first storage plate 51 and the second storage plate 52 are used to store the standby gun tip box 62 and the discarded gun tip box 61 respectively. When the rotating disk 41 rotates, the positions of the two supporting brackets 452 can be swapped. One of the supporting brackets 452 is close to the center position of the turntable 31, and the supporting bracket 452 rotates around the first track 621 as the turntable 31 rotates. The other supporting bracket 452 is far away from the center position of the turntable 31 and rotates around the second track 611. All the standby gun tip boxes 62 are located on the first track 621, and all the discarded gun tip boxes 61 are located on the second track 611. That is to say, the position directly below each storage component 5 is the second position, and the carrying component 4 moves to the second position so that the carrying component 4 can be docked with each storage component 5.

[0048] The first storage plate 51 and the second storage plate 52 are provided with a through hole 53, which can accommodate the discarded gun tip box 61 and the standby gun tip box 62 and penetrate the first storage plate 51 and the second storage plate 52 from top to bottom. A limiting member 54 is provided above the through hole 53, and the limiting member 54 is used to fix or release the discarded gun tip box 61 and the standby gun tip box 62. The standby gun tip box 62 and the discarded gun tip box 61 are respectively arranged at the upper ends of the first storage plate 51 and the second storage plate 52 in a stacked manner, and are fixed or released by the limiting member 54, so that the standby gun tip box 62 passes through the through hole 53 from top to bottom and is arranged on the supporting bracket 452, and the discarded gun tip box 61 passes through the through hole 53 from bottom to top and is recovered on the second storage plate 52.

[0049] The position-limiting member 54 includes a fixed box 541, a first support block 542 is arranged in the fixed box 541, and a hydraulic cylinder for driving the first support block 542 to move horizontally is arranged in the fixed box 541. There are two groups of position-limiting members 54, which are arranged at the front and rear sides of the through-hole 53 respectively, so that the two first support blocks 542 are respectively located at the front and rear side walls of the through-hole 53, and can move relatively, so that the two first support blocks 542 are close to or away from each other. A second support block 453 is arranged on the bearing bracket 452. There are also two second support blocks 453, which are arranged at positions close to the center of the bearing assembly 4 and away from the center of the bearing assembly 4, respectively. When the bearing assembly 4 is located at the second position, the two second support blocks 453 are respectively located on the left and right sides of the through-hole 53. In the present application, the bottom of the gun head box is provided with two groups of support grooves corresponding to the first support block 542 and the second support block 453, respectively, and the two first support blocks 542 are telescoped back and forth in the horizontal direction to support or separate one group of support grooves. The two second support blocks 453 can act on another group of support grooves to provide support from below. The first support block 542 and the second support block 453 can act on the discarded gun tip box 61 and the standby gun tip box 62 simultaneously or separately. Therefore, the gun tip box can be transferred back and forth between the carrying assembly 4 and the storage assembly 5 through the cooperation of the first support block 542 and the second support block 453.

[0050] The specific structure of the bearing assembly 4 is as follows:

[0051] The bearing assembly 4 includes a rotating disk 41, which is rotatably mounted on the upper end of the rotating disk 31. A rotating groove is provided at the upper end of the rotating disk 31 near the edge, and the rotating disk 41 is rotatably mounted in the rotating groove. The rotating groove is provided with an element for driving the rotating disk 31 to rotate, such as a motor or a hydraulic cylinder, so that the rotating disk 41 can rotate around its axis. A lifting platform 42 is provided at the center of the rotating disk 41. By providing the lifting platform 42, the height of the bearing bracket 452 can be adjusted to make it more suitable for the mechanical arm 2, so that the mechanical arm 2 can pick up the gun head at a selectable height. A telescopic cylinder 43 for driving the lifting platform 42 to move up and down is installed at the upper end of the rotating disk 41. The telescopic cylinder 43 is provided with two groups, which are respectively provided on both sides of the lifting platform 42. The telescopic cylinder 43 can be an oil cylinder, a gas cylinder or an electric cylinder. At the same time, in order to improve stability, a support seat 44 is fixedly connected to the center of the upper end of the rotating disk 41. When the telescopic cylinder 43 is in a shortened state, the lifting platform 42 acts on the upper end of the support seat 44.

[0052] When the lifting platform 42 rises or falls, it can drive the second support block 453 to rise or fall. Therefore, the horizontally movable first support block 542 and the vertically movable second support block 453 can cooperate with each other to realize the transfer of the gun tip box. It should be noted that the lifting and lowering of the supporting bracket 452 is realized based on the movement of the lifting platform 42, so the second support blocks 453 located on different supporting brackets 452 will rise and fall at the same time, but because the movement direction of the second support block 453 is not synchronized during the recovery and arrangement of the discarded gun tip box 61 and the standby gun tip box 62, the operation will be slightly cumbersome.

[0053] In order to further solve the above problem, a lifting bar 451 is fixedly connected to one side of the load-bearing bracket 452 close to the lifting platform 42. In order to improve stability, two lifting bars 451 are provided. The lifting bars 451 are slidably installed on the lifting platform 42. A driving unit 46 is installed on the lifting platform 42. The driving unit 46 is used to drive the lifting bars 451 to slide along the vertical direction. That is to say, in this embodiment, by setting the lifting bars 451 as a secondary lifting drive mechanism and driven by the driving unit 46, the independent lifting operation of the two load-bearing brackets 452 can be realized, and useless operations can be reduced. By setting a lifting mechanism with two sets of strokes, the operation accuracy can be improved.

[0054] A slide groove 421 running through the lifting platform 42 is provided, and a sliding protrusion 4511 is fixedly connected to the side wall of the lifting bar 451. The sliding protrusion 4511 is slidably set in the slide groove 421, and the length of the slide groove 421 is not less than 3 cm to improve the limiting effect and avoid the lifting bar 451 from tilting. Furthermore, a rubber strip can be embedded on the side wall of the slide groove 421 to increase the friction between the sliding protrusion 4511 and the side wall.

[0055] At the same time, the first storage plate 51 and the second storage plate 52 are provided with a clearance groove 55, so that the lifting bar 451 can pass through the clearance groove 55, thereby avoiding interference between the lifting bar 451 and the first storage plate 51 or the second storage plate 52. Further, the first storage plate 51 and the second storage plate 52 can be integrally formed by a bending process, the other end of the first storage plate 51 is bent downward and fixedly connected to the housing 1, and the other end of the second storage plate 52 is fixedly connected to the fixed shaft 32.

[0056] The drive unit 46 includes a motor, the output end of the motor is connected to a gear 461, and a rack 4512 is provided on the side wall of the lifting bar 451. The lifting bar 451 and the rack 4512 are both vertically arranged. The gear 461 and the rack 4512 are meshed with each other. In order to prevent the rack 4512 from falling downward due to gravity, the motor can adopt an electromagnetic self-locking motor. Alternatively, a worm gear transmission is adopted between the output end of the motor and the gear 461, and the worm gear is used to achieve a self-locking effect.

[0057] As a further optimization, in order to reduce the equipment cost of the motor and optimize the operation steps. The height of the first storage plate 51 is lower than the height of the second storage plate 52, and the height difference between the two is equal to the height of a gun tip box. In this way, when a discarded gun tip box 61 to be recycled is placed on one of the supporting brackets 452, the other supporting bracket 452 is in an unloaded state. As the lifting platform 42 moves upward, the discarded gun tip box 61 can be brought into contact with the discarded gun tip box 61 at the bottom of the second storage plate 52, and the second support block 453 on the other side of the supporting bracket 452 can be brought into contact with the standby gun tip box 62 at the bottom of the first storage plate 51. In other words, by setting the height of the first storage plate 51 and the second storage plate 52, the height difference of the supporting brackets 452 on both sides can be eliminated, so that when the lifting platform 42 moves upward, the supporting brackets 452 on both sides can act on the upper gun tip box at the same time.

[0058] The number of the driving units 46 is one group, and the gear 461 is simultaneously engaged with the racks 4512 on both sides. When the gear 461 rotates in one direction, it will drive the two racks 4512 to move in opposite directions. When one group of the bearing brackets 452 moves upward, the other group of the bearing brackets 452 moves downward. Therefore, when the lifting platform 42 moves upward, the discarded gun tip box 61 on the bearing component 4 contacts the discarded gun tip box 61 on the storage component 5, and the second support block 453 on the other side of the bearing component 4 contacts the standby gun tip box 62 on the storage component 5. The limiter 54 is controlled to retract the first support block 542. Then the gear 461 is controlled to rotate, so that the racks on both sides move upward and downward respectively, so that the discarded gun tip box 61 moves to the upper side of the through-hole 53, and the standby gun tip box 62 moves to the lower side of the through-hole 53, and then the first support block 542 is extended. Thereby, the transfer of the gun tip box between the bearing component 4 and the storage component 5 is realized. An automated operation process is realized.

[0059] In addition, the two sets of racks 4512 are simultaneously meshed with the same gear 461, which can balance the weight and offset part of the gravity.

[0060] Here’s how it works:

[0061] In the initial state Figure 3 As shown, the carrying assembly 4 is in the first position, and the robot arm 2 can take the gun tips from the carrying assembly 4. When the gun tips on the carrying assembly 4 are used up, the discarded gun tip box 61 is located on the left side of the carrying assembly 4, and the rotating disk 31 is driven to rotate. The carrying assembly 4 is moved to the second position, that is, directly below any storage assembly 5, as shown in FIG. Figure 7Then, the telescopic cylinder 43 is controlled to extend, and the lifting platform 42 moves upward, so that the discarded gun tip box 61 on the left side contacts the discarded gun tip box 61 on the storage assembly 5, and the second support block 453 on the right side contacts the standby gun tip box 62 on the storage assembly 5, as shown. Figure 8 shown.

[0062] Then, the hydraulic cylinder is controlled to retract the first support block 542 inward, so that the weight of all the gun tip boxes acts on the bearing assembly 4. Then, the motor is controlled to drive the gear 461 to rotate. Since the gear 461 simultaneously engages the racks 4512 on both sides, the rack 4512 on the left side moves upward to the height of a gun tip box, so that the discarded gun tip box 61 moves to the top of the second storage plate 52. At the same time, the rack 4512 on the right side moves downward to the height of a gun tip box, so that the unused gun tip box moves downward to the bottom of the second storage plate 52. Fig. 9 At this time, the first support block 542 is controlled to extend outward to fix the gun tip box above the storage assembly 5.

[0063] Next, the telescopic cylinder 43 is controlled to shorten and the motor is made to rotate in the opposite direction, so that the two supporting brackets 452 return to the same height. Fig.10 Finally, the rotating disk 41 is controlled to rotate, so that the positions of the two supporting brackets 452 are swapped, and the standby gun tip box 62 is moved to the left side of the supporting bracket 452, as shown. Fig.11 As shown, at the same time, the turntable 31 rotates to move the carrying assembly 4 to the first position so that the robot arm 2 can continue to obtain the gun head.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
