Description

Technical Field

[0002] Biochips are the product of the combination of modern micro-processing technology and biotechnology.

[0021] The outer surface of the circumference of the turntable 2 is fixedly mounted with a plurality of fixed blocks 31, one end of the rotating plate 12 passes through the outer surface of the fixed block 31 and is fixedly mounted with a driven gear 32, a fixed shaft is fixedly mounted on the outer surface of one side of the fixed block 31, a sector gear 33 is rotatably mounted on the outer surface of the fixed shaft, the sector gear 33 is meshed with the driven gear 32, an eccentric block is fixedly mounted on the outer surface of the sector gear 33, a sliding column 35 is fixedly mounted on the outer surface of the other end of the eccentric block, a driving ring 7 is fixedly mounted on the inner wall of the C-shaped frame 5, a protrusion 701 is provided on the upper surface of the driving ring 7, the protrusion 701 is provided on the upper surface of the driving ring 7 close to the dust cover 3, the sliding column 35 is abutted against the upper surface of the driving ring 7, one end of the fixed shaft passes through the outer surface of the sector gear 33 and is sleeved with a torsion spring 34, one end of the torsion spring 34 is fixedly connected to the outer surface of the circumference of the fixed shaft, and the other end of the torsion spring 34 is fixedly connected to the outer surface of the sector gear 33.

[0022] The slide column 35 is driven to move by the turntable 2. When the slide column 35 moves to the protrusion 701 position of the drive ring 7, the slide column 35 drives the fan gear 33 to rotate. The fan gear 33 drives the rotating plate 12 to rotate 180° through the driven gear 32. At this time, the cleaned biochip will be flipped to the inside of the dust cover 3, and then the tiny probes on the biochip will be detected by the optical detection lens 4. The device can clean the dust adhering to the surface of the biochip, and place it in a dust-free environment during detection, so as to avoid dust blocking the probes on the surface of the biochip, thereby ensuring the sensitivity and accuracy of the detection.

[0023] In this embodiment, the outer surface of the rotating plate 12 located on one side of the biochip is provided with a mounting groove 21, and two L-shaped clamping rods 23 are symmetrically rotated and installed on the inner wall of the mounting groove 21. The outer surfaces of the two L-shaped clamping rods 23 near one end of the sliding column 35 are fixedly installed with clamping columns 26, and the circumferential outer surfaces of the clamping columns 26 are provided with an annular clamping groove.

[0024] The stopper 30 is driven to move by the turntable 2. When the stopper 30 moves to the position of the protrusion 702 on the lower surface of the driving ring 7, the protrusion 702 and the stopper 30 are counteracted, so that the stopper 30 drives the slide bar 24 to move close to the protrusion 702. The slide bar 24 drives the moving plate to move close to the protrusion 702 through the slider 27. The moving plate drives the two L-shaped clamping rods 23 to move away from each other through the guide column 28 and the guide groove 29. The two L-shaped clamping rods 23 drive the clamping columns 26 to move away from each other. At this time, the biochip restricted by the two clamping columns 26 is released and falls into the collection box, which is convenient for subsequent centralized processing.

[0025] In this embodiment, the bottom end of the rotating shaft passes through the lower surface of the base 1 and is fixedly installed with a driven sheave 11. The lower surface of the base 1 is rotatably installed with an active dial 10, and the active dial 10 is meshed with the driven sheave 11. A shell 8 is fixedly installed on the lower surface of the base 1, and a driving motor 9 is fixedly installed on the lower surface of the shell 8.

Four radial grooves are equidistantly arranged in the circumferential direction of the outer surface of the driven sheave 11. The active dial 10 is driven to rotate by the driving motor 9. The active dial 10 drives the rotating shaft to intermittently rotate 90° through the driven sheave 11, and drives the turntable 2 to intermittently rotate 90° through the rotating shaft.

[0026] It should be noted that when the present invention is used, the operator inserts the biochip into the annular clamping groove of the two clamping columns 26, and one end of the biochip is against the stopper 22. The guide column 28 passes through the guide groove 29 through the action of the spring 25, driving the L-shaped clamping rod 23 to clamp the biochip. The device is convenient for quickly limiting the position of the biochip, which is convenient for subsequent detection. The driving motor 9 drives the active dial 10 to rotate, and the active dial 10 drives the rotating shaft to intermittently rotate 90° through the driven groove wheel 11, and drives the turntable 2 to intermittently rotate 90° through the rotating shaft, and the turntable 2 drives the rotating plate 12 to intermittently rotate 90° to the inside of the dust cover 6, and the rotating plate 12 drives the biochip to move to the inside of the dust cover 6 at the same time. When the biochip just moves to the inside of the dust cover 6, since the turntable 2 is still rotating, the driving disk 19 is driven by the rotating shaft to rotate, and the driving disk 19 cooperates with the cam driving groove 20 and the driving column 17, so that the push rod 15 drives the compression plate 14 to compress the air inside the compression box 13, and the air inside the compression box 13 enters the inside of the dust cover 6 through the air outlet, and the blown air will affect the biochip. The outer surface is cleaned so that the air blows off the dust adhering to the outer surface of the biochip, and the blown dust is discharged from the one-way air outlet valve 18. At the same time, the slide column 35 is driven to move through the turntable 2. When the slide column 35 moves to the protrusion 701 position of the drive ring 7, the slide column 35 drives the fan gear 33 to rotate, and the fan gear 33 drives the rotating plate 12 to rotate 180° through the driven gear 32. At this time, the cleaned biochip will be turned over to the inside of the dust cover 3, and then the tiny probe on the biochip will be detected by the optical detection lens 4. The device can clean the dust adhering to the surface of the biochip, and place it in a dust-free environment during detection, so as to avoid dust blocking the probe on the surface of the biochip, thereby ensuring the sensitivity and accuracy of the detection; At the same time, the stopper 30 is driven to move through the turntable 2. When the stopper 30 moves to the position of the protrusion 702 on the lower surface of the driving ring 7, the protrusion 702 and the stopper 30 are counteracted, so that the stopper 30 drives the slide bar 24 to move close to the protrusion 702. The slide bar 24 drives the moving plate to move close to the protrusion 702 through the slider 27. The moving plate drives the two L-shaped clamping rods 23 to move away from each other through the guide column 28 and the guide groove 29. The two L-shaped clamping rods 23 drive the clamping columns 26 to move away from each other. At this time, the biochip restricted by the two clamping columns 26 is released and falls into the collection box, which is convenient for subsequent centralized processing.

[0027] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
