Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a continuous detection device for biochips. Background Art

[0002] A biochip is a product of the combination of modern microfabrication technology and biotechnology, and is a micro-device that can complete certain biological reaction functions fabricated inside or on the surface of a flat carrier through photolithography or biomolecular self-assembly technology. According to different uses, biochips are mainly divided into two categories. One is a bioelectronic chip, which is used for the manufacture of bioelectronic products such as bio-computers. The other is a bioanalysis chip, which is used for the operation of various biological macromolecules, cell tissues, and the detection of biochemical reactions.

[0003] An existing biochip detection device (Publication No.: CN112896769A) has at least the following drawbacks:

[0004] When the above patent is in use, by setting a connecting rod on the box cover, when in use, the box cover is opened, so that the box cover drives the connecting rod to rotate, the connecting rod drives the connected fixed seat to move, and the T-shaped slider on the moving plate connected to the fixed seat slides in the chute, so that the moving plate moves upward from the box body under the drive of the cover plate, and the detection device on the moving plate extends out of the box body, which is convenient for carrying out detection. Since the detection of the biochip in the above patent is carried out in the external environment, the dust adhered to the surface of the biochip is not removed before detection, and the dust will cover the surface of the biochip, blocking the probes on the surface of the biochip, resulting in signal loss or attenuation, thus affecting the sensitivity and accuracy of detection. Summary of the Invention

[0005] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose a continuous detection device for biochips.

[0034] Refer to Figures 1-12, A continuous detection device for a biochip, comprising a base 1 and multiple legs fixedly installed equidistantly on the lower surface of the base 1. A rotating shaft is rotatably installed on the upper surface at the middle position of the base 1, and a turntable 2 is fixedly installed at the top of the rotating shaft. Four openings 201 are equidistantly penetrated in the circumferential direction on the upper surface of the turntable 2. A rotating plate 12 is rotatably installed between the inner walls of the four openings 201. A biochip is arranged on the outer surface of one side of the rotating plate 12. A C-shaped frame 5 is fixedly installed on the circumferential outer surface of the base 1. A dust-proof cover 3 is fixedly installed on the lower surface of the C-shaped frame 5 near the top. The bottom end of the dust-proof cover 3 is flush with the upper surface of the turntable 2. The dust-proof cover 3 is arranged above two adjacent rotating plates 12. Shields 301 are fixedly installed on both end faces of the dust-proof cover 3 near the two ends. The surface of the shield 301 is larger than the surface of the rotating plate 12. A dust-removing cover 6 is fixedly installed on the upper surface of the base 1. The top end of the dust-removing cover 6 is flush with the lower surface of the turntable 2. The dust-removing cover 6 is arranged directly below the dust-proof cover 3 and overlaps with it by one rotating plate 12. An optical detection lens 4 is fixedly installed on the upper surface of the dust-proof cover 3. The bottom end of the optical detection lens 4 penetrates the top wall of the dust-proof cover 3 and is arranged directly above the rotating plate 12. A compression box 13 is fixedly installed on the outer surface of the dust-removing cover 6 near the rotating shaft. A compression plate 14 is slidably installed on the inner wall of the compression box 13. A push rod 15 is fixedly installed on the outer surface of the compression plate 14 near the rotating shaft. A driving column 17 is fixedly installed on the upper surface of the other end of the push rod 15. A driving disk 19 is fixedly installed on the circumferential outer surface of the rotating shaft near the top. A cam driving groove 20 is formed on the lower surface of the driving disk 19. The driving column 17 is slidably installed on the inner wall of the cam driving groove 20. The cam driving groove 20 is composed of four convex grooves and four concave grooves alternatingly. The air outlet end of the compression box 13 penetrates the inner wall of the dust-removing cover 6 and is connected to its interior. A one-way intake valve 16 is fixedly installed on the outer surface of one side of the compression plate 14. An air filter element is arranged at the intake end of the one-way intake valve 16. A one-way outlet valve 18 is arranged on the outer surface of the dust-removing cover 6 opposite to the compression box 13. The air outlet end of the compression box 13 is arranged below the rotating plate 12.

[0035] The rotation of the driving disk 19 is driven by the rotating shaft. Through the cooperation of the cam driving groove 20 and the driving column 17 on the driving disk 19, the push rod 15 drives the compression plate 14 to compress the air inside the compression box 13. The air inside the compression box 13 enters the interior of the dust-removing cover 6 through the air outlet end, and the blown air will clean the outer surface of the biochip, so that the air blows off the dust adhered to the outer surface of the biochip. The blown-off dust will be discharged from the one-way outlet valve 18. Through this device, the dust adhered to the surface of the biochip can be blown off and cleaned.

[0036] In this embodiment, a plurality of fixing blocks 31 are fixedly installed on the circumferential outer surface of the turntable 2. One end of the turntable 12 penetrates through the outer surface of the fixing block 31 and is fixedly installed with a driven gear 32. A fixing shaft is fixedly installed on the outer surface of one side of the fixing block 31. A sector gear 33 is rotatably installed on the circumferential outer surface of the fixing shaft. The sector gear 33 meshes with the driven gear 32. An eccentric block is fixedly installed on the outer surface of the sector gear 33. A sliding column 35 is fixedly installed on the outer surface of the other end of the eccentric block. A driving ring 7 is fixedly installed on the inner wall of the C-shaped frame 5. A protrusion 701 is arranged on the upper surface of the driving ring 7. The protrusion 701 is arranged on the upper surface of the driving ring 7 close to the dust-proof cover 3. The sliding column 35 abuts against the upper surface of the driving ring 7. One end of the fixing shaft penetrates 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 circumferential outer surface of the fixing shaft, and the other end of the torsion spring 34 is fixedly connected to the outer surface of the sector gear 33.

[0037] The turntable 2 drives the sliding column 35 to move. When the sliding column 35 moves to the position of the protrusion 701 of the driving ring 7, the sliding column 35 drives the sector gear 33 to rotate. The sector gear 33 drives the turntable 12 to rotate 180° through the driven gear 32. At this time, the cleaned biochip will flip to the inside of the dust-proof cover 3, and then the tiny probes on the biochip are detected by the optical detection lens 4. The dust adhered to the surface of the biochip can be cleaned by this device, and it is in a dust-free environment during detection, avoiding dust from blocking the probes on the surface of the biochip, ensuring the sensitivity and accuracy of the detection.

[0038] In this embodiment, an installation sink 21 is formed on the outer surface of the turntable 12 on the side of the biochip. Two L-shaped clamping rods 23 are symmetrically and rotatably installed on the inner wall of the installation sink 21. Clamping columns 26 are fixedly installed on the outer surfaces of the two L-shaped clamping rods 23 near one end of the sliding column 35. An annular clamping groove is formed on the circumferential outer surface of the clamping column 26. The biochip is arranged between the inner walls of the annular clamping groove. A sliding groove 2701 is formed on the inner wall of the installation sink 21. A slider 27 is slidably installed on the inner wall of the sliding groove 2701. A moving plate is fixedly installed at the top of the slider 27. Two guide grooves 29 are symmetrically formed on the outer surface of the moving plate. Guide columns 28 are fixedly installed on the outer surfaces of the other ends of the L-shaped clamping rods 23. The guide columns 28 are slidably installed on the inner walls of the guide grooves 29. A stop block 22 is arranged on the outer surface of the turntable 12 at the end far from the driven gear 32. A sliding rod 24 is fixedly installed on the outer surface of the slider 27 close to the driven gear 32. The other end of the sliding rod 24 penetrates through the end face of the turntable 12 close to the driven gear 32 and is fixedly installed with a stop head 30. The stop head 30 is arranged below the driving ring 7. A convex block 702 is fixedly installed on the outer surface of the driving ring 7 on the side opposite to the dust removal cover 6. The stop head 30 abuts against the outer surface of the convex block 702. A spring 25 is sleeved on the outer surface of the sliding rod 24. The spring 25 is arranged between the slider 27 and the inner wall of the sliding groove 2701 close to the driven gear 32.

[0039] Drive the stopper 30 to move through the turntable 2. When the stopper 30 moves to the position of the bump 702 on the lower surface of the drive ring 7, due to the abutment between the bump 702 and the stopper 30, the stopper 30 drives the slide bar 24 to move closer to the bump 702. The slide bar 24 drives the moving plate to move closer to the bump 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 posts 28 and the guide grooves 29. The two L-shaped clamping rods 23 drive the clamping posts 26 to move away from each other. At this time, the biochip restricted by the two clamping posts 26 is released and falls into the collection box, facilitating subsequent centralized processing.

[0040] In this embodiment, the bottom end of the rotating shaft penetrates through the lower surface of the base 1 and is fixedly installed with a driven sprocket 11. The lower surface of the base 1 is rotatably installed with a driving dial 10. The driving dial 10 is engaged with the driven sprocket 11. The lower surface of the base 1 is fixedly installed with a housing 8. The lower surface of the housing 8 is fixedly installed with a driving motor 9. The output end of the driving motor 9 penetrates through the outer surface of the housing 8 and is fixedly installed with the rotation center of the driving dial 10. Four radial grooves are equidistantly arranged in the circumferential direction on the outer surface of the driven sprocket 11. Drive the driving dial 10 to rotate through the driving motor 9. The driving dial 10 drives the rotating shaft to intermittently rotate 90° through the driven sprocket 11, and drives the turntable 2 to intermittently rotate 90° through the rotating shaft.

[0041] It should be noted that when the present invention is in use, the operator inserts the biochip into the annular clamping groove between the two clamping posts 26, and one end of the biochip abuts against the stopper 22. Due to the acting force of the spring 25, the guide post 28 drives the L-shaped clamping rod 23 to clamp the biochip through the guide groove 29. The position of the biochip can be quickly restricted through this device, facilitating subsequent detection;

[0042] 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;

[0043] 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.

[0044] 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. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
