Description

Technical Field

[0001] This utility model relates to the field of microfluidic spectral chips, and more particularly to a support device for microfluidic spectral chips. Background Technology

[0002] Microfluidics integrates the basic operational units of biological, chemical, and medical analysis processes, such as sample preparation, reaction, separation, and detection, onto a single chip at the micrometer scale, automating the entire analysis process.

[0003] During the chip manufacturing process, microfluidic chips are prone to short circuits due to their extremely delicate internal circuitry, requiring testing by inspection agencies.

[0004] However, most existing testing institutions can only perform clamping tests on the same type of chip. If the chip size is increased or decreased, the testing institution is not easy to adjust, and its applicability is weak. Furthermore, if you want to test the back of the chip, you need to disassemble and fix the chip again, which is quite troublesome. Utility Model Content

[0005] To overcome the problems that most existing testing institutions can only perform clamping and testing on the same type of chip, and that it is inconvenient to adjust the testing institution if the chip size is increased or decreased, resulting in weak applicability, and that if the back of the chip is to be tested, the chip needs to be disassembled and fixed again, which is quite troublesome.

[0006] The technical solution of this utility model is as follows: a support device for a microfluidic spectral chip, including a support frame and a rotating frame. Clamping plates are movably connected to both sides of the inner wall of the rotating frame. An adjustment assembly is threadedly connected to the opposing surfaces of the two clamping plates. The adjustment assembly is connected between the clamping plates and the rotating frame. A clamping block is movably connected to one side of each clamping plate. Lifting seats are provided on both sides of the rotating frame. A rotating assembly is fixedly connected to the inner side of one of the lifting seats. The rotating frame is rotatably connected to the lifting seat via the rotating assembly. One end of the lifting seat extends to the inner side of the support frame, and the lifting seat is movably connected to the support frame. A second servo motor is fixedly connected to the top of the support frame. The output of the second servo motor... The first lead screw is fixedly connected to the end of the lifting seat, and the bottom end of the first lead screw extends to the outside of the lifting seat and is rotatably connected to the support frame. The adjustment component includes a first servo motor, the output end of the first servo motor is fixedly connected to a transmission rod, one end of the transmission rod is rotatably connected to a second lead screw, and both ends of the second lead screw extend to the outside of the clamping tray and are rotatably connected to the rotating frame. When the first servo motor drives the transmission rod to rotate, the first servo motor, through the transmission rod and the second lead screw, causes the two clamping trays to move inside the rotating frame. The rotation component includes a third servo motor, the output end of the third servo motor is fixedly connected to a first transmission gear, and one end of the first transmission gear extends to the outside of the rotating frame.

[0007] Preferably, the positions of the two clamping trays are adjusted by a first servo motor in conjunction with a transmission rod and a second lead screw. Since the clamping block and the clamping tray are movably connected by a connecting spring, chips of different sizes and thicknesses can be clamped. The rotating frame is flipped inside the lifting seat by a third servo motor in conjunction with a first transmission gear and a second transmission gear.

[0008] Preferably, a control panel is fixedly connected to the front end of the support frame, and an infrared detection mechanism is fixedly connected to the top of the control panel. The control panel is electrically connected to the infrared detection mechanism, the first servo motor, the second servo motor, and the third servo motor, and can be controlled through the control panel.

[0009] Preferably, the infrared detection mechanism includes an infrared scanning camera, which can scan the chip surface.

[0010] Preferably, rotating shafts are provided on both sides of the rotating frame, with one end of the rotating shaft extending to the inside of the lifting seat. One end of one of the rotating shafts is provided with a second transmission gear. The first transmission gear and the second transmission gear mesh with each other. When the third servo motor drives the first transmission gear to rotate, the third servo motor, in conjunction with the first transmission gear and the second transmission gear, causes the rotating frame to flip inside the lifting seat.

[0011] Preferably, one end of the transmission rod is provided with a bevel gear, and the transmission rod is connected to the second lead screw through the bevel gear. When the first servo motor drives the transmission rod to rotate, the transmission rod, in conjunction with the bevel gear, drives the second lead screw to rotate.

[0012] Preferably, the second lead screw is a double-threaded lead screw with symmetrical threads at both ends. The second lead screw is threadedly connected to two clamping plates. When the second lead screw rotates, the two clamping plates are displaced relative to each other on the outside of the second lead screw.

One end of the connecting spring extends to the inner wall of the clamping tray. The clamping block is movably connected to the clamping tray through the connecting spring. When the chip is placed inside the clamping tray, the clamping block cooperates with the connecting spring to fit the chip.

[0014] The beneficial effects of this utility model are:

[0015] 1. The support device for the microfluidic spectral chip adjusts the position of the two clamping trays by means of a first servo motor, a transmission rod, and a second lead screw.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment of a support device for a microfluidic spectral chip, including a support frame 1 and a rotating frame 5. Clamping plates 6 are movably connected to both sides of the inner wall of the rotating frame 5. An adjustment assembly is threadedly connected to the opposing surfaces of the two clamping plates 6. The adjustment assembly is connected between the clamping plates 6 and the rotating frame 5. A clamping block 7 is movably connected to one side of each clamping plate 6. Lifting seats 11 are provided on both sides of the rotating frame 5. A rotating assembly is fixedly connected to the inner side of one of the lifting seats 11. The rotating frame 5 is rotatably connected to the lifting seat 11 via the rotating assembly. One end of the lifting seat 11 extends to the inner side of the support frame 1, and the lifting seat 11 is movably connected to the support frame 1. A second servo motor 9 is fixedly connected to the top of the support frame 1. A first lead screw 10 is fixedly connected to the output end of the second servo motor 9. The bottom end of the first lead screw 10 extends to the outer side of the lifting seat 11 and is rotatably connected to the support frame 1. The adjustment assembly includes a first servo motor 8. A transmission rod 15 is fixedly connected to the output end of the first servo motor 8. A second lead screw 10 is rotatably connected to one end of the transmission rod 15. 6. The two ends of the second lead screw 16 extend to the outside of the clamping tray 6 and are rotatably connected to the rotating frame 5. When the first servo motor 8 drives the transmission rod 15 to rotate, the first servo motor 8, through the transmission rod 15 and the second lead screw 16, causes the two clamping trays 6 to move inside the rotating frame 5. The rotating assembly includes a third servo motor 12. The output end of the third servo motor 12 is fixedly connected to the first transmission gear 13. One end of the first transmission gear 13 extends to the outside of the rotating frame 5. Thus, according to the microfluidic spectral chips of different sizes, the position of the two clamping trays 6 can be adjusted by the first servo motor 8 in conjunction with the transmission rod 15 and the second lead screw 16. Since the clamping block 7 and the clamping tray 6 are movably connected by the connecting spring 17, chips of different sizes and thicknesses can be clamped. After the rotating frame 5 is raised to a certain height by the second servo motor 9 in conjunction with the first lead screw 10 and the lifting seat 11, the rotating frame 5 is flipped inside the lifting seat 11 by the third servo motor 12 in conjunction with the first transmission gear 13 and the second transmission gear 14.

[0025] Please see Figures 2-3 In this embodiment, a control panel 2 is fixedly connected to the front end of the support frame 1, and an infrared detection mechanism 3 is fixedly connected to the top of the control panel 2. The control panel 2 is electrically connected to the infrared detection mechanism 3, the first servo motor 8, the second servo motor 9, and the third servo motor 12. The control panel 2 can control the infrared detection mechanism 3, the first servo motor 8, the second servo motor 9, and the third servo motor 12. The infrared detection mechanism 3 includes an infrared scanning camera, which can scan the chip surface.

[0026] Please see Figures 4-5In this embodiment, rotating shafts are provided on both sides of the rotating frame 5, with one end of each shaft extending to the inner side of the lifting seat 11. One end of one shaft is equipped with a second transmission gear 14, and the first transmission gear 13 meshes with the second transmission gear 14. When the third servo motor 12 drives the first transmission gear 13 to rotate, the third servo motor 12, in conjunction with the first transmission gear 13 and the second transmission gear 14, causes the rotating frame 5 to rotate inside the lifting seat 11. A bevel gear is provided at one end of the transmission rod 15, and the transmission rod 15 is connected to the second lead screw 16 via the bevel gear. When the first servo motor 8 drives the transmission rod 15 to rotate, the transmission rod 15 rotates... The moving rod 15, in conjunction with the bevel gear, drives the second lead screw 16 to rotate. The second lead screw 16 is a double-threaded lead screw with symmetrical threads at both ends. The second lead screw 16 is threadedly connected to two clamping plates 6. When the second lead screw 16 rotates, the two clamping plates 6 are displaced relative to each other on the outside of the second lead screw 16. The clamping plates 6 are L-shaped. A connecting spring 17 is fixedly connected to the top of the clamping block 7. One end of the connecting spring 17 extends to the inner wall of the clamping plate 6. The clamping block 7 is movably connected to the clamping plate 6 through the connecting spring 17. When the chip is placed inside the clamping plate 6, the clamping block 7, in conjunction with the connecting spring 17, adheres to the chip.

[0027] During operation, the power is turned on and the device is started. Then, the microfluidic spectroscopy chip is placed in the clamping tray 6. The positions of the two clamping trays 6 are adjusted by the first servo motor 8 in conjunction with the transmission rod 15 and the second lead screw 16. Since the clamping block 7 and the clamping tray 6 are movably connected by the connecting spring 17, chips of different sizes and thicknesses can be clamped. After fixing, the microfluidic spectroscopy chip is detected by the infrared detection mechanism 3. After the rotating frame 5 is raised to a certain height by the second servo motor 9 in conjunction with the first lead screw 10 and the lifting seat 11, the rotating frame 5 is flipped inside the lifting seat 11 by the third servo motor 12 in conjunction with the first transmission gear 13 and the second transmission gear 14, so that the infrared detection mechanism 3 can perform comprehensive detection of the microfluidic spectroscopy chip.

[0028] Through the above steps, the positions of the two clamping plates 6 are adjusted by the first servo motor 8 in conjunction with the transmission rod 15 and the second lead screw 16. Since the clamping block 7 and the clamping plate 6 are movably connected by the connecting spring 17, chips of different sizes and thicknesses can be clamped. The rotating frame 5 is rotated inside the lifting seat 11 by the third servo motor 12 in conjunction with the first transmission gear 13 and the second transmission gear 14. This solves the problem that most existing testing mechanisms can only clamp and test the same type of chip. If the chip size is increased or decreased, the testing mechanism is not easy to adjust and has weak applicability. In addition, if the back of the chip is to be tested, the chip needs to be disassembled and fixed again, which is quite troublesome.
