Referring to fig. 1 to 3, a plate washer according to an embodiment of the present invention includes a liquid injection mechanism 100, a liquid suction mechanism 200, and a tray mechanism 300.
Specifically, the liquid injection mechanism 100 includes the liquid injection head 10. It can be appreciated that the liquid injection mechanism 100 may further include a liquid injection pump, a liquid injection pipeline, and the like, wherein the liquid injection pump is connected with the liquid injection head 10 through the liquid injection pipeline, and is used for conveying liquid to the liquid injection head 10 through the liquid injection pipeline and finally injecting the liquid into the micropores on the microporous plate W through the liquid injection head 10.
The liquid suction mechanism 200 includes a liquid suction head 20 and a first driving mechanism 21, the liquid suction head 20 and the liquid injection head 10 are arranged side by side along the left-right direction, and the first driving mechanism 21 is connected with the liquid suction head 20 to drive the liquid suction head 20 to move up and down, that is, the first driving mechanism 21 can drive the liquid suction head 20 to move up and down. It can be appreciated that the liquid suction mechanism 200 may further include a liquid suction pump, a waste liquid bottle, a liquid suction pipeline, and the like, where the liquid suction pump is communicated with the waste liquid bottle through a conduit, the waste liquid bottle is connected with the liquid suction head 20 through the liquid suction pipeline, and negative pressure is generated through the liquid suction pump, so that the liquid suction head 20 sucks the liquid cleaned in the micropores of the microporous plate W into the liquid suction pipeline, and then enters the waste liquid bottle through the liquid suction pipeline.
The tray mechanism 300 includes a tray 30 and a second driving mechanism 31, wherein the tray 30 is suitable for loading the microplate W, and the second driving mechanism 31 is connected to the tray 30 to drive the tray 30 to rotate at a position below the pipetting head 20 and the pipetting head 10.
That is, the tray mechanism 300 is located below the pipetting head 10 and the pipetting head 20, the tray 30 is used to mount the microwell plate W, and the second driving mechanism 31 can drive the tray 30 to move in the left-right direction and can move to below the pipetting head 10 and below the pipetting head 20.
In a specific operation, a microplate W is mounted on the tray 30, and each of the microwells in the microplate W has liquid remaining after detection. First, the tray 30 is driven to move under the filling head 10 by the second driving mechanism 31, and then the filling head 10 fills the cleaning liquid into each of the wells on the microplate W. Then, the tray 30 is driven to move to the lower side of the liquid sucking head 20 by the second driving mechanism 31, and then the liquid sucking head 20 is driven to move downwards by the first driving mechanism 21, so that the liquid sucking head 20 is inserted into each micro-hole in the lower micro-hole plate W, and the liquid after cleaning in the micro-hole is sucked.
According to the plate washer provided by the embodiment of the invention, the plate washer is provided with the independent liquid injection mechanism 100 and the liquid suction mechanism 200, the tray mechanism 300 is configured, the tray mechanism 300 comprises the tray 30 and the second driving mechanism 31, the tray 30 is suitable for loading the micro-pore plate W, the second driving mechanism 31 can drive the tray 30 to rotate at the position below the liquid suction head 20 of the liquid suction mechanism 200 and the liquid injection head 10 of the liquid injection mechanism 100, and thus, the liquid injection operation and the liquid suction operation can be respectively finished by utilizing the liquid injection mechanism 100 and the liquid suction mechanism 200. The separate liquid injection mechanism 100 and the liquid suction mechanism 200 can simplify the structure and facilitate the processing. In addition, when cleaning or maintenance is needed, the liquid injection mechanism 100 or the liquid suction mechanism 200 can be disassembled in a targeted manner, and the cleaning or maintenance is more convenient due to the simple structure of the internal pipelines and the channels.
In addition, since the cleaning liquid is injected into the micro holes of the micro holes plate W and the cleaning liquid is relatively clean when the liquid injection head 10 injects the liquid, the problem of clogging inside the liquid injection head 10 is relatively small, and the liquid suction head 20 sucks the liquid in the micro holes of the micro holes W during the liquid suction, and the liquid in the micro holes contains residual sample, reagent, cleaning liquid, etc., so that the inside of the liquid suction head 20 is easily clogged due to the sample (e.g., blood), and therefore, the liquid suction head 20 is relatively frequently cleaned and maintained. In the invention, the liquid suction head 20 and the liquid injection head 10 are independently arranged, so that the liquid suction head and the liquid injection head are not mutually influenced, and the liquid suction head and the liquid injection head are convenient to clean and maintain in a targeted manner.
Referring to fig. 1 to 2, for example, the plate washer may further include a housing 400 and a fixing plate 401 disposed in the housing 400, the liquid filling head 10 is fixedly mounted on a front side surface of the housing 400, the first driving mechanism 21 and the second driving mechanism 31 are mounted on the fixing plate 401 in the housing, the liquid filling head 20 extends from the front side surface, the tray 30 is located outside the housing 400 and below the liquid filling head 20 and the liquid filling head 10, so that the structure is simpler and more compact, and the appearance is simpler.
In one embodiment of the present invention, the first driving mechanism 21 includes a bracket 211, a floating plate 214, and a first motor 215, wherein the bracket 211 is provided with a screw 212 and a first guide bar 213 extending in an up-down direction. The floating plate 214 is in threaded fit with the screw rod 212, and the floating plate 214 is in sliding fit with the first guide rod 213. An output shaft of the first motor 215 extends in the up-down direction and is connected to the screw 212 to drive the screw 212 to rotate so as to move the floating plate 214 up-down. The pipette head 20 is coupled to the floating plate 214 to move up and down with the floating plate 214.
That is, the floating plate 214 has a screw hole and a through hole, the screw rod 212 is screw-fitted with the screw hole, and the first guide rod 213 is slide-fitted with the through hole. When the first motor 215 is operated, the output shaft of the first motor 215 drives the screw rod 212 to rotate, and the screw rod 212 drives the floating plate 214 to move in the up-down direction due to the threaded engagement between the screw rod 212 and the floating plate 214, and at the same time, the floating plate 214 can be ensured to move in the up-down direction more smoothly and reliably due to the sliding engagement between the first guide rod 213 and the floating plate 214 by the guide action of the first guide rod 213. Since the liquid suction head 20 is connected to the floating plate 214 by fixing the same with a screw, the floating plate 214 can drive the liquid suction head 20 to move up and down when moving up and down, and the structure is simple and the up and down movement is smooth and reliable.
Referring to fig. 3, in one embodiment of the present invention, the second driving mechanism 31 includes a transmission assembly, a clamping block 314, a guiding assembly, and a second motor 317, where the transmission assembly includes a driving wheel 311, a driven wheel 312, and a driving belt 313, the driving belt 313 is sleeved between the driving wheel 311 and the driven wheel 312, and the clamping block 314 is clamped on the driving belt 313; the guiding assembly comprises a first support 318, a second support, a second guiding rod 315 connected between the first support 318 and the second support, and a sliding block 316 slidably sleeved on the second guiding rod 315, wherein the second guiding rod 315 extends along the left-right direction, and the sliding block 316 is fixedly connected with the clamping block 314; an output shaft of the second motor 317 extends in the front-rear direction and is connected to the driving wheel 311, so as to drive the driving wheel 311 to rotate, so that the driving belt 313 drives the clamping block 314 and the sliding block 316 to move left and right; the tray 30 is fixedly connected with the sliding block 316 so as to slide left and right along with the sliding block 316.
When the second motor 317 works, the output shaft of the second motor 317 drives the driving wheel 311 to rotate, the driving wheel 311 drives the driving belt 313 to rotate, and since the clamping block 314 is clamped and fixed on the driving belt 313, the driving belt 313 can drive the clamping block 314 to move in a left-right direction when rotating, for example, when the second motor 317 rotates in one of a forward direction and a reverse direction, the driving belt 313 rotates clockwise, at this time, the clamping block 314 moves rightward, when the second motor 317 rotates in the other of the forward direction and the reverse direction, the driving belt 313 rotates counterclockwise, at this time, the clamping block 314 moves leftward, and thus, the clamping block 314 can be driven to move left and right by the forward rotation and the reverse rotation of the second motor 317. Since the sliding block 316 is slidably disposed on the second guide rod 315 and the sliding block 316 is fixedly connected to the clamping block 314, the sliding block 316 can move left and right along with the clamping block 314, and can move left and right smoothly and reliably under the guidance of the second guide rod 315. Since the tray 30 is fixedly connected to the slider 316, the tray 30 can be driven to move in the left-right direction when the slider 316 moves in the left-right direction.
