Description

Technical Field

[0001] The utility model relates to the field of automated liquid handling equipment, and particularly relates to a platform system of a liquid handling workstation. Background Art

[0002] With the rapid development of life science and technology, biochemical laboratories are faced with more complex objects and an increasing number of samples. The traditional manual operation method can no longer meet the requirements of high-throughput sample processing. Relying solely on the manual operation method has problems such as high labor intensity, low work efficiency, and easy errors (especially when dealing with high-throughput sample processing requirements), and also increases the operation difficulty.

[0003] In the currently marketed liquid handling workstations, most instrument platforms are integrated, differentiated by plate positions, and the smallest operation unit also operates by plate positions. For large instruments with a large number of plate positions, for plate positions far from the operation position, when the operator operates, he needs to reach his hand into a far position, place the plate position at the far end, and it is also inconvenient for operations such as positioning or fixing. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a platform system of a liquid handling workstation for the deficiencies of the prior art, which is convenient for personnel to operate in units of cassette positions and plate positions, avoids operating plate positions at a long distance, facilitates overall operation and switching, and supports arbitrary interchange operations of cassette assembly positions and the combined use of cassettes, adapters, and consumables, breaking the limitations and inconveniences of the traditional liquid handling workstation that only uses plate positions as the operation unit.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows: A platform system of a liquid handling workstation includes a platform base plate, multiple cassettes, and multiple sets of cassette locking mechanisms. Multiple cassette positions are provided in regions on the platform base plate, each cassette is detachably assembled in one of the cassette positions, multiple plate positions are provided in regions on each cassette, each plate position is used for detachably assembling an adapter, and the adapter is used for placing consumables. The multiple sets of cassette locking mechanisms are installed on the platform base plate, each set of cassette locking mechanisms corresponds to one of the cassette positions, and each set of cassette locking mechanisms is used to lock and fix a cassette in one of the cassette positions.

[0006] On the platform substrate of the platform system of the liquid handling workstation of the present utility model, a plurality of card positions are arranged in regions. Each card is detachably assembled in a card position, and a plurality of board positions are arranged in regions on each card. Each board position is used for detachably assembling an adapter, facilitating operation by personnel in units of card positions and board positions, and supporting any interchange operation of the card assembly positions as well as the combined use of cards, adapters, and consumables, breaking the limitations and inconveniences of traditional liquid handling workstations that only use board positions as operation units. At the same time, a card locking function is integrated to ensure reliable assembly of the card.

[0007] Preferably, each set of the card locking mechanisms includes a locking pin, a pressing pin, a limiting compression spring, a locking pin mounting seat, a limiting seat, and a locking connection plate. The locking pin mounting seat is fixed at the bottom of the front side of the platform substrate. The limiting seat is fixed at the bottom of the locking pin mounting seat. The pressing pin is vertically and slidably penetrated through the platform substrate, the locking pin mounting seat, and the limiting seat. The limiting compression spring is sleeved on the pressing pin and is compressed and arranged between the locking pin mounting seat and the limiting seat. The locking pin is vertically and slidably penetrated through the platform substrate and the locking pin mounting seat. The bottom ends of the locking pin and the pressing pin are connected by the locking connection plate. The top ends of the locking pin and the pressing pin respectively extend out from the top of the platform substrate. A plurality of limiting blocks are installed at the top of the rear side of the platform substrate. After a card is assembled in the card position corresponding to each set of the card locking mechanisms, the rear side of the card contacts the plurality of limiting blocks, the front side of the card contacts the locking pin, and the card is locked and fixed. The locking pin and the pressing pin of the above card locking mechanism are connected as a whole through the locking connection plate, and the locking pin can move synchronously with the pressing pin. Under normal circumstances, the limiting compression spring is in a free compression state (the minimum compression amount), the locking pin and the pressing pin are both in the highest position, and the card is limited and locked. When the pressing pin is pressed down, the limiting compression spring is further compressed, the locking pin descends synchronously with the pressing pin, and the locking pin is disengaged from the card. At this time, the pull plate can be gently pulled out and lifted to complete the unloading of the pull plate, and the operation is simple and convenient. When a card is loaded into the card position, after the card presses over the locking pin from the top of the locking pin, the limiting compression spring will return to the free compression state, and the pressing pin will bounce up to the highest position, and the front side of the card is limited by the connection pin.

[0008] Furthermore, the locking pin includes a wide-diameter section and a narrow-diameter section that are integrally arranged up and down. The lower part of the wide-diameter section is in surface contact with the platform substrate. The locking pin designed as above can reduce the contact area between the locking pin and the platform substrate, making the synchronous movement of the locking pin and the pressing pin smoother.

[0009] Preferably, a plurality of card detection modules are installed on the platform substrate. Each card detection module corresponds to one card position, and each card detection module is used to detect the type of the card assembled at the corresponding card position. The detection and identification of the type of the card (such as a pipe card, a perforated plate card, etc.) can reduce human operation errors and facilitate the table layout operation of the platform system.

[0010] Specifically, each card detection module includes a cover body, a base, and a plurality of detection units. The base is fixed at the top of the rear side of the platform substrate, the cover body covers and is fixed on the base. Each detection unit includes a detection optocoupler, an optocoupler baffle, a detection pin, and a detection compression spring. The detection optocoupler is fixed on the base, the detection pin is horizontally and slidably penetrated through the base, the front end of the detection pin extends out from the front side of the base, the detection compression spring is sleeved on the detection pin, and the detection compression spring is assembled between the detection pin and the base. The optocoupler baffle is fixed at the rear end of the detection pin. After the card is assembled in place at the card position corresponding to each card detection module, the rear side of the card presses the front end of the detection pin of the card detection module, causing the detection pin to move backward. When the optocoupler baffle triggers the detection optocoupler, the detection optocoupler feeds back a signal to the control system of the liquid handling workstation, and the control system of the liquid handling workstation identifies the type of the card assembled at the card position corresponding to the card detection module. In addition to the function of detecting the type of the card, the above-mentioned card detection module can also play a certain positioning role for the card with its detection pin, and the detection compression spring can also play a certain boosting role for the card, improving the safety of the card unloading operation. After the card is assembled in place, its front side is positioned by the locking pin, and the rear side is positioned by the limit block and the detection pin together. When it is necessary to unload the card installed at the card position, press the pressing pin. When the locking pin is separated from the card, under the thrust of the detection compression spring, the card will be slightly ejected forward, and at this time, the operator can gently pull out and lift the pull plate to quickly complete the unloading of the pull plate.

[0011] Preferably, a plurality of guide bars are provided on the platform substrate. One guide bar is provided on each of the left and right sides of each card position. A plurality of positioning pins are installed on each guide bar. Guide grooves are provided on each of the left and right sides of each card. When assembling each card, each guide groove slides into the card position along a plurality of the positioning pins until each card is assembled in place at the card position. The cooperation of the guide bar and the guide groove has a simple structure, facilitates the installation and disassembly operation of the card, and is conducive to realizing the rapid positioning and limiting of the card.

[0012] Preferably, each of the adapters includes an adapter body. A number of elastic buckles are integrally provided on four sides of the adapter body. The inner side surface of each elastic buckle is an inclined surface that obliquely faces the inner side of the adapter body from top to bottom. The number of elastic buckles is used to clamp the consumables. A number of positioning holes and a number of first screw holes are provided on the adapter body. A number of positioning posts are fixed on each card board and a number of second screw holes are provided. Each positioning post corresponds to one positioning hole, and each second screw hole corresponds to one first screw hole. The adapter adopts an integrally arranged elastic buckle structure, which has a good guiding and positioning effect and allows a certain amount of deformation. Therefore, it can match the assembly requirements of card boards within a certain size range and meet the installation of various types of card boards, such as PCR plates, deep well plates, and some pipette tip boxes, etc. Thus, the types of adapters can be reduced and the operation is convenient. According to the actual situation, the adapter and the card board can be assembled by the one-to-one cooperation of a number of positioning posts and a number of positioning holes. Or, further, screws can be installed in the first screw holes and the corresponding second screw holes, and the adapter can be fixed on the card board by a number of screws.

[0013] Compared with the prior art, the present invention has the following advantages: On the platform substrate of the platform system of the liquid handling workstation of the present invention, multiple card board positions are provided in regions. Each card board is detachably assembled to a card board position, and multiple board positions are provided in regions on each card board. Each board position is used to detachably assemble an adapter, which is convenient for personnel to operate in units of card board positions and board positions during operation. The adapter, consumables, reagents, etc. can be first assembled onto the card board, and then the card board as a whole can be installed into the card board position on the platform system, avoiding long-distance operation of the board positions and facilitating overall operation and switching. At the same time, the platform system supports arbitrary interchange operations of the card board assembly positions and the combined use of the card board, adapter, and consumables, breaking the limitations and inconveniences of the traditional liquid handling workstation that only uses the board position as the operation unit. At the same time, the card board locking function is integrated to ensure reliable assembly of the card board. Description of the Drawings

[0026] The platform system of the liquid - handling workstation in the embodiment, as Figures 1 to 5As shown in the figure, it includes a platform substrate 1, six card boards 2 and six sets of card board locking mechanisms 3. Six card board positions 11 are arranged in areas on the platform substrate 1. Each card board 2 is detachably assembled to a card board position 11. Specifically, seven guiding bars 12 are arranged on the platform substrate 1. One guiding bar 12 is provided on each of the left and right sides of each card board position 11. A plurality of positioning pins 13 are installed on each guiding bar 12. Guiding grooves 21 are respectively provided on the left and right sides of each card board 2. When assembling each card board 2, each guiding groove 21 slides into the card board position 11 along a plurality of positioning pins 13 until each card board 2 is assembled in place at the card board position 11; four board positions 22 are arranged in areas on each card board 2. Each board position 22 is used for detachably assembling an adapter 23. The adapter 23 is used for placing consumables. Specifically, taking the Figure 5 plate-type adapter shown in the figure as an example, each adapter 23 includes an adapter body. A plurality of elastic buckles 24 are integrally arranged on the four sides of the adapter body. The inner side surface of each elastic buckle 24 is an inclined surface 25 that slopes obliquely from top to bottom towards the inside of the adapter body.

Each positioning column 39 corresponds to one positioning hole 26, and each second screw hole 30 corresponds to one first screw hole 27; six sets of card board locking mechanisms 3 are installed on the platform substrate 1. Each set of card board locking mechanisms 3 corresponds to a card board position 11. Each set of card board locking mechanisms 3 is used to lock and fix a card board 2 at a card board position 11.

[0027] In this embodiment, as Figure 6 and Figure 7As shown in the figure, each set of card locking mechanisms 3 includes a locking pin 31, a pressing pin 32, a limiting compression spring 33, a locking pin mounting seat 34, a limiting seat 35, and a lock catch connecting plate 36. The locking pin mounting seat 34 is fixed to the bottom of the front side of the platform base plate 1, and the limiting seat 35 is fixed to the bottom of the locking pin mounting seat 34. The pressing pin 32 is vertically and slidably inserted through the platform base plate 1, the locking pin mounting seat 34, and the limiting seat 35. The limiting compression spring 33 is sleeved on the pressing pin 32 and is compressed and arranged between the locking pin mounting seat 34 and the limiting seat 35. The locking pin 31 is vertically and slidably inserted through the platform base plate 1 and the locking pin mounting seat 34. The bottom ends of the locking pin 31 and the pressing pin 32 are connected by the lock catch connecting plate 36. The top ends of the locking pin 31 and the pressing pin 32 respectively extend out from the top of the platform base plate 1. A number of limiting blocks 14 are installed on the top of the rear side of the platform base plate 1. After the card 2 is assembled in place at the card position 11 corresponding to each set of card locking mechanisms 3, the rear side of the card 2 contacts the number of limiting blocks 14, the front side of the card 2 contacts the locking pin 31, and the card 2 is locked and fixed. Specifically, the locking pin 31 includes a wide-diameter section 37 and a narrow-diameter section 38 that are integrally arranged up and down, and the lower part of the wide-diameter section 37 is in surface contact with the platform base plate 1.

[0028] In this embodiment, 6 card detection modules 4 are installed on the platform base plate 1, and a detection cover 40 is provided on the upper side of the 6 card detection modules 4.

Specifically, as Figure 8 and Figure 9 shown, each card detection module 4 includes a cover body 41, a base 42, and 3 detection units 43. The base 42 is fixed to the top of the rear side of the platform base plate 1, the cover body 41 covers and is fixed to the base 42. Each detection unit 43 includes a detection optocoupler 44, an optocoupler baffle 45, a detection pin 46, and a detection compression spring 47. The detection optocoupler 44 is fixed to the base 42, the detection pin 46 is horizontally and slidably inserted through the base 42, the front end of the detection pin 46 extends out from the front side of the base 42, the detection compression spring 47 is sleeved on the detection pin 46 and is assembled between the detection pin 46 and the base 42, and the optocoupler baffle 45 is fixed to the rear end of the detection pin 46. After the card 2 is assembled in place at the card position 11 corresponding to each card detection module 4, the rear side of the card 2 presses the front end of the detection pin 46 of the card detection module 4, causing the detection pin 46 to move backward. When the optocoupler baffle 45 triggers the detection optocoupler 44, the detection optocoupler 44 feeds back a signal to the control system of the liquid handling workstation, and the control system of the liquid handling workstation identifies the type of the card 2 assembled at the card position 11 corresponding to the card detection module 4.

[0029] When operating, the operator can use the pallet position 11 and the plate position 22 as units. First, assemble the plate adapter 231, the test tube adapter 232, and the tip box adapter 233 onto the microplate 234 respectively. Then, assemble the microplate 234 onto the plate adapter 231, assemble the test tube 235 onto the test tube adapter 232, and assemble the tip box 236 onto the tip box adapter 233. The following shows the effect after different types of adapters are installed on a pallet 2. Figure 3 As shown; then, according to requirements, add the corresponding reagents to the microplate 234 or the test tube 235; finally, gently push the entire pallet 2 along the guide bar 12 and the positioning pin 13 into the pallet position 11 until the rear side of the pallet 2 contacts and presses the front end of several limit blocks 14. At this time, the front side of the pallet 2 is limited by the limit blocks 14, and the pallet 2 cannot move on the horizontal plane and can maintain precise positioning, thus completing the assembly of one pallet 2. By following the same operation, the assembly of the other 5 pallets 2 can be completed (for the schematic diagram of the effect after assembly, see Figure 4 ), which is convenient for the operator to use the pallet position 11 and the plate position 22 as units during operation, avoiding operating the plate position at a long distance and facilitating overall operation and switching.
