Description

Technical Field

[0001] This disclosure generally relates to the field of liquid bladder technology for microfluidic chips, and specifically to an automated liquid bladder injection and packaging device. Background Technology

[0002] Microfluidic chip technology is a new technology that precisely manipulates and controls nanoliter and picoliter-level fluids (biological sample fluids) within micrometer-scale channels. This technology allows for the integration or near-integration of basic operational units involved in sample preparation, reaction, separation, detection, cell culture, sorting, and lysis—all common in chemistry and biology—onto a single chip of a few square centimeters (or even smaller). A network of microchannels forms the core, enabling controllable fluid flow throughout the system, thus replacing various functions in conventional chemical or biological laboratories. The fundamental characteristic and greatest advantage of microfluidic chip laboratories lies in the flexible combination and large-scale integration of multiple unit technologies on a controllable micro-platform. Reagent pre-packaging is one of the key functions of microfluidic chips in portable analytical applications.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Please refer to Figures 1-6 This application provides an automated liquid filling and packaging device for liquid bladders, comprising:

[0049] A mounting platform mechanism, wherein the mounting platform mechanism has a mounting surface 1;

[0050] The feeding mechanism 100 includes a storage space 101 and a temporary placement position 102, which is used to transfer the liquid bladder 2 stored in the storage space 101 to the temporary placement position 102.

[0052] A plurality of actuators are mounted on the mounting surface 1 and arranged around the rotating part 200, with each actuator corresponding to an execution station of the rotating part 200; starting from the feeding mechanism 100, along the first rotation direction, the plurality of actuators are sequentially a material picking mechanism 300, a liquid injection mechanism 400, a label placement mechanism 500, a packaging mechanism 600, and a material receiving mechanism 700; the material picking mechanism 300 is used to transfer the liquid bladder 2 from the temporary placement position 102 to the liquid bladder mounting position 3;

[0053] When the rotating part 200 rotates, the liquid bladder mounting position 3, on which the liquid bladder 2 is placed, passes sequentially through the material taking mechanism 300, the liquid injection mechanism 400, the label placement mechanism 500, the sealing mechanism 600, and the material receiving mechanism 700.

[0054] Specifically, the mounting platform mechanism has a first mounting frame 16 and a second mounting frame 17, and the feeding mechanism 100 is mounted on the first mounting frame 16. Optionally, the feeding mechanism 100 is a vibrating feeder; the feeding mechanism 100 includes a housing, and the housing is provided with the storage space 101 and a vibration device. The unsealed liquid bladder 2 is placed in the storage space 101. Through the vibration action of the vibration device, the unsealed liquid bladder 2 in the storage space 101 is moved to the temporary placement position 102 for the picking mechanism 300 to grab; multiple unsealed liquid bladders 2 can be placed on the temporary placement position 102 at the same time, ensuring that there are liquid bladders 2 that can be grabbed each time the picking mechanism 300 moves to the temporary placement position 102.

[0055] Specifically, the mounting surface 1 is placed on the second mounting bracket 17, and the rotating part 200 is rotatably mounted on the mounting surface 1 and can rotate around its own axis by a motor drive. The rotating part 200 has a plurality of evenly spaced perforated holes 18, which are used to reduce the weight of the rotating part 200, thereby reducing the burden on the motor. Optionally, the rotating part 200 is a circular rotating disk. A plurality of liquid bladder mounting positions 3 are evenly arranged at the edge of the upper surface of the rotating part 200. The liquid bladder mounting positions 3 are used to fix the liquid bladder 2, so that when the rotating part 200 rotates, it can drive the liquid bladder 2 to rotate, and liquid can be injected and sealed during the rotation process. In this embodiment, there are eight liquid bladder mounting positions 3; in other embodiments, the number of liquid bladder mounting positions 3 is not limited.

[0056] Specifically, in this embodiment, the rotating part 200 is evenly provided with eight execution stations, and the two adjacent execution stations are 45° apart. Each execution mechanism corresponds to one execution station, and each execution mechanism is used to perform different operations on the liquid bladder 2.

[0057] The material handling mechanism 300 includes:

[0058] The first bracket 310 is mounted on the mounting surface 1;

[0059] The clamping part 320 is used to grasp the liquid bag 2 located at the temporary placement position 102 and transfer it to the liquid bag mounting position 3 located at the first execution position 4, which is the execution position corresponding to the material handling mechanism 300.

[0060] A first adjustment part 330 is connected to the clamping part 320 and the first bracket 310. The first adjustment part 330 is used to drive the clamping part 320 to move along a first direction and back and forth between the temporary placement position 102 and the liquid bladder mounting position 3. The first direction is perpendicular to the mounting surface 1.

[0061] Specifically, the first adjustment unit 330 includes a material-feeding forward cylinder 331 and a material-feeding lifting cylinder 332. The material-feeding forward cylinder 331 is fixedly mounted on the first bracket 310, and its free end can move freely along the direction of reciprocating between the temporary placement position 102 and the first execution position. The material-feeding lifting cylinder 332 is mounted on the free end of the material-feeding forward cylinder 331, and the free end of the material-feeding lifting cylinder 332 can extend and retract freely in the vertical direction. The clamping unit 320 is a material-feeding clamping cylinder, and the clamping unit 320 is mounted on the free end of the material-feeding lifting cylinder 332.

[0062] The material handling process is as follows:

[0063] First, the material-grabbing forward cylinder 331 drives the material-grabbing lifting cylinder 332 to move above the temporary placement position 102. Then, the material-grabbing lifting cylinder 332 drives the clamping part 320 to move downward and grab the liquid bag 2. Next, the material-grabbing lifting cylinder 332 raises the clamping part 320, and the material-grabbing forward cylinder 331 drives the material-grabbing lifting cylinder 332 to move above the liquid bag mounting position 3 located at the first execution station 4. The material-grabbing lifting cylinder 332 drives the clamping part 320 to descend. Finally, the clamping part 320 places the liquid bag 2 on the liquid bag mounting position 3 located at the first execution station 4.

[0064] The injection mechanism 400 includes:

[0065] The second bracket 410 is mounted on the mounting surface 1;

[0066] The injection unit 420 is suspended above the second execution station 5 and is used to insert the liquid bladder 2 located at the second execution station 5 and to inject liquid into the liquid bladder 2; the second execution station 5 is the execution station corresponding to the injection mechanism 400.

[0067] The second adjustment part 430 is connected to the injection part 420 and the second support 410; the second adjustment part 430 is used to drive the injection part 420 to move along the first direction.

[0068] Specifically, the second adjusting part 430 is a liquid injection cylinder, which is mounted on the second bracket 410, and its free end is movable in the vertical direction. The liquid injection part 420 is a liquid injection capillary, which is mounted on the free end of the second adjusting part 430 and is vertically arranged; the liquid injection part 420 is connected to a liquid peristaltic pump, and is inserted into the liquid bladder 2. When the rotating part 200 moves the unsealed liquid bladder 2 to the second execution station 5, the second adjusting part 430 moves the liquid injection part 420 downward until it is inserted into the liquid bladder 2. The liquid injection part 420 injects liquid into the liquid bladder 2 through the liquid peristaltic part, and after injection, the second adjusting part 430 moves the liquid injection part 420 upward.

[0069] The bidding mechanism 500 includes a bidding component 510 and a bidding component 520.

[0070] The bidding component 510 includes a feeding section 511, a discharging platform 512, and a driving section 513. The driving section 513 is used to convey the sticker 14 with aluminum foil 13 installed on the feeding section 511 to the discharging platform 512.

[0071] Furthermore, the label dispensing component 510 also includes a suction section 514, which is disposed between the material dispensing section 511 and the material dispensing platform 512, for adsorbing the sticker 14 so as to stably convey the aluminum foil 13.

[0072] Specifically, the aluminum foil consumable label includes a protective paper 15, the sticker 14, and an aluminum foil 13 between the two, with the aluminum foil 13 attached to the sticker 14.

[0073] Specifically, the label dispensing assembly 510 further includes an upper receiving section 515, a cylinder pressing section 516, a retractable peeling section 517, a lower receiving section 518, a guide shaft 519, and a servo motor. The aluminum foil consumable label is installed on the dispensing section 511 and guided by the guide shaft 519. The protective paper 15 is then wound around the upper receiving section 515. The sticker 14 passes sequentially through the suction section 514, the cylinder pressing section 516, the retractable peeling section 517, the dispensing platform 512, and the drive section 513, finally winding around the lower receiving section 518.

[0074] The bidding process is as follows:

[0075] The feeding section 511 rotates counterclockwise to release the aluminum foil consumable label. The servo motor drives the upper receiving section 515 and the lower receiving section 518 to rotate respectively. After passing through the guide shaft 519, the protective paper 15 and the sticker 14 separate, and the protective paper 15 is wrapped around the upper receiving section 515. The sticker 14, carrying the aluminum foil 13, moves to the position of the suction section 514. The suction section 514 sucks up the sticker 14 to prevent it from being too loose and avoids positional deviation. When the vacuum label suction section 521 sucks up the aluminum foil 13, the retracting peeling section 517 retracts to peel the aluminum foil 13 off the sticker 14. At the same time, the cylinder pressing section 516 descends and presses down the sticker 14 to prevent label suction failure or positional deviation of the aluminum foil 13. After the aluminum foil 13 is sucked away, the remaining sticker 14 is finally wound into the lower receiving section 518.

[0076] The label dispensing assembly 520 includes a vacuum label suction unit 521, a first driving unit 522, and a second driving unit 523. The vacuum label suction unit 521 is used to adsorb the aluminum foil 13 located at the discharge platform 512 and transfer it to the liquid bladder 2 located at the third execution station 6, which is the execution station corresponding to the label dispensing mechanism 500. The first driving unit 522 is used to drive the vacuum label suction unit 521 to move along the first direction. The second driving unit 523 is used to drive the vacuum label suction unit 521 back and forth between the discharge platform 512 and the third execution station 6.

[0077] Furthermore, the label-releasing assembly 520 also includes a vacuum detection unit 524, which is electrically connected to the first drive unit 522 and the second drive unit 523 respectively. The vacuum detection unit 524 is used to detect the vacuum value of the vacuum label-absorbing unit 521, and when the vacuum value is greater than or equal to a set value, it instructs the first drive unit 522 and the second drive unit 523 to operate.

[0078] Specifically, the label placement assembly 520 further includes a support frame 525 and a vacuum generator 526. The first drive unit 522 is a vertical axis stepper motor, and the second drive unit 523 is a horizontal axis stepper motor. The second drive unit 523 is mounted on the support frame 525, the first drive unit 522 is mounted on the second drive unit 523, and the vacuum label suction part 521 is mounted on the first drive unit 522 and communicates with the vacuum generator 526.

[0079] The labeling process is as follows:

[0080] First, the second drive unit 523 drives the first drive unit 522 to move above the discharge platform 512. Then, the first drive unit 522 drives the vacuum label-collecting part 521 to move downward, generating a vacuum environment through the vacuum generator 526. Next, the vacuum label-collecting part 521 adsorbs the aluminum foil 13 on the discharge platform 512. Then, the first drive unit 522 drives the vacuum label-collecting part 521 to move upward. Next, the second drive unit 523 drives the first drive unit 522 to move above the third execution station 6. Finally, the first drive unit 522 drives the vacuum label-collecting part 521 to move downward, and the vacuum label-collecting part 521 places the aluminum foil 13 on the liquid bladder 2 at the third execution station 6.

[0081] Furthermore, a pressing spring 527 is also provided at the bottom of the vacuum suction part 521. When the vacuum suction part 521 moves downward and places the aluminum foil 13, the pressing spring 527 exerts a downward pressing force on the aluminum foil 13, so that the aluminum foil 13 fits the liquid bladder 2 more tightly.

[0082] Furthermore, the label-issuing mechanism 500 also includes a pre-packaging component 530, which comprises:

[0083] Heating element 531, the heating element 531 is suspended above the third execution station 6, the heating element 531 is columnar and extends along the first direction;

[0084] The third adjustment part 532 is mounted on the mounting surface 1 and connected to the heating part 531, and is used to drive the heating part 531 to move along the first direction.

[0085] Specifically, the third adjustment part 532 is a pre-packaged pressing cylinder, which is mounted on the mounting surface 1. The free end of the third adjustment part 532 is movable in the vertical direction. The heating part 531 is arranged in the numerical direction and is mounted on the free end of the third adjustment part 532. The heating part 531 is suspended above the liquid bladder mounting position 3 at the third execution station 6. When the vacuum label suction part 521 places the aluminum foil 13 on the liquid bladder 2, the third adjustment part 532 drives the heating part 531 to descend. The columnar heating part 531 heats up the aluminum foil 13 and the liquid bladder 2 when they come into contact.

[0086] The packaging mechanism 600 includes:

[0087] The third bracket 610 is mounted on the mounting surface 1;

[0088] The packaging part 620 is suspended above the fourth execution station 7, which is the execution station corresponding to the packaging mechanism 600; the packaging part 620 can generate heat.

[0089] The fourth adjustment part 630 connects the encapsulation part 620 and the third bracket 610, and is used to drive the encapsulation part 620 to move along the first direction.

[0090] Specifically, the fourth adjusting part 630 is a sealing cylinder, and its free end is movable in the vertical direction; the sealing part 620 is a heating block, and it is mounted on the free end of the fourth adjusting part 630. When the liquid bladder 2, after being preheated by the pre-sealing component 530, rotates to the fourth execution station 7, the fourth adjusting part 630 drives the sealing part 620 to move downward, and the aluminum foil 13 and the liquid bladder 2 are sealed by the heating effect of the sealing part 620.

[0091] In a preferred embodiment, the actuator further includes a snap-on mechanism 800 and a hot-riveting mechanism 900; the snap-on mechanism 800 is disposed between the packaging mechanism 600 and the receiving mechanism 700, and is used to bend the tail of the aluminum foil 13 and fasten the tail of the aluminum foil 13 onto the limiting part, the limiting part being disposed on the liquid bladder 2; the hot-riveting mechanism 900 is disposed between the snap-on mechanism 800 and the receiving mechanism 700, and is used to hot-rivet the limiting part.

[0092] Specifically, the snap-on mechanism 800 corresponds to the fifth execution station 9. The snap-on mechanism 800 includes a fifth bracket 810, a snap-on cylinder 820, a snap-on fixture 830, and a bending rod 840. The fifth bracket 810 is mounted on the mounting surface 1. The snap-on cylinder 820 is mounted on the fifth bracket 810, and the free end of the snap-on cylinder 820 is movable in the vertical direction. The snap-on fixture 830 is mounted on the free end of the snap-on cylinder 820 and is suspended above the liquid bladder mounting position 3 at the fifth execution station 9. The bending rod 840 is mounted on the fifth bracket 810, and the bending rod 840 is offset from the liquid bladder mounting position 3 at the fifth execution station 9. In the vertical direction, the bending rod 840 is located between the liquid bladder mounting position 3 and the snap-on fixture 830.

[0093] The snap-on process is as follows: when the liquid bladder 2 rotates from the fourth execution station 7 to the fifth execution station 9, the tail of the aluminum foil 13 contacts the bending rod 840, and the bending rod 840 bends the tail of the aluminum foil 13; then the snap-on cylinder 820 drives the snap-on fixture 830 to press down, and then the snap-on fixture 830 snaps the tail of the aluminum foil 13 onto the limiting part.

[0094] Specifically, the hot riveting mechanism 900 corresponds to the seventh execution station 11. The hot riveting mechanism 900 includes a sixth bracket 910, a hot riveting cylinder 920, and a hot riveting copper block 930. The sixth bracket 910 is mounted on the mounting surface 1, and the hot riveting cylinder 920 is mounted on the sixth bracket 910. The free end of the hot riveting cylinder 920 is movable in the vertical direction. The hot riveting copper block 930 is mounted on the free end of the hot riveting cylinder 920 and is positioned above the liquid bladder mounting position 3 of the seventh execution station 11. The hot riveting copper block 930 is heatable.

[0095] The hot riveting process is as follows:

[0096] When the liquid bladder 2 rotates to the seventh execution station 11, the hot riveting cylinder 920 drives the hot riveting copper block 930 to move downward, and the limiting part is hot riveted by the heat generated by the hot riveting copper block 930.

[0097] Furthermore, a sixth execution station 10 is provided between the fifth execution station 9 and the seventh execution station 11. The sixth execution station 10 is an unused execution station, and the liquid bladder 2 located on the sixth execution station 10 is not processed. The sixth execution station 10 is used to facilitate the operator to observe the processing status of the liquid bladder 2.

[0098] The receiving mechanism 700 includes:

[0099] The mounting surface 1 includes a storage portion 710 and a connecting portion 720. The storage portion 710 is disposed on the bottom side of the mounting surface 1 and is used to store the encapsulated liquid bladder 2. The connecting portion 720 penetrates the mounting surface 1 and is disposed corresponding to the storage portion 710.

[0100] The fourth bracket 730 is mounted on the mounting surface 1;

[0101] The material handling unit 740 is used to grab the liquid bag 2 on the finished product execution station 8 and transfer it above the connecting part 720. The finished product execution station 8 is the execution station corresponding to the receiving mechanism 700.

[0102] The fifth adjustment part 750 connects the material taking part 740 and the fourth bracket 730. The fifth adjustment part 750 is used to drive the material taking part 740 to move along the first direction and back and forth between the finished product execution station 8 and the connecting part 720.

[0103] Specifically, the storage section 710 is a storage box, and the storage section 710 is placed at the bottom of the mounting surface 1; the connecting section 720 is a through hole opened on the mounting surface 1. The fifth adjustment section 750 includes a material receiving retraction cylinder 751 and a material receiving lifting cylinder 752. The material receiving retraction cylinder 751 is mounted on the fourth bracket 730, and the free end of the material receiving retraction cylinder 751 is retractable in the horizontal direction; the material receiving lifting cylinder 752 is mounted on the free end of the material receiving retraction cylinder 751, and the free end of the material receiving lifting cylinder 752 is movable in the vertical direction; the material picking section 740 is a material picking cylinder, and the material picking section 740 is mounted on the free end of the material receiving lifting cylinder 752.

[0104] The material receiving process is as follows:

[0105] First, the receiving retraction cylinder 751 drives the receiving lifting cylinder 752 to move above the finished product execution station 8; then, the receiving lifting cylinder 752 drives the picking part 740 to descend, and the picking part 740 picks up the hot-riveted liquid bag 2; then, the receiving lifting cylinder 752 drives the picking part 740 to rise; then, the receiving retraction cylinder 751 drives the receiving lifting cylinder 752 to move above the connecting part 720; finally, the picking part 740 lowers the liquid bag 2, and the liquid bag 2 enters the storage part 710 through the connecting part 720, completing the entire production process.

[0106] Working principle: First, the unsealed liquid bladder 2, pre-stored in the storage space 101, is transferred to the temporary placement position 102 by the feeding mechanism 100. Then, the positions are adjusted by the material-grabbing forward cylinder 331 and the material-grabbing lifting cylinder 332, and the clamping part 320 grasps the liquid bladder 2 located on the temporary placement position 102 and transfers it to the liquid bladder mounting position 3 of the first execution station 4. As the rotating part 200 rotates clockwise by 45°, the liquid bladder 2 located on the first execution station 4 rotates to the second execution station 5, and is then lowered by the liquid injection part 420. The liquid is pressed and injected into the liquid bladder 2; then the rotating part 200 rotates clockwise again by 45°, and the liquid bladder 2 rotates to the third execution station 6. The label dispensing component 510 separates the aluminum foil 13 and the sticker 14. Then, the vacuum label suction part 521 sucks up the aluminum foil 13 and places it on the liquid bladder 2 at the third execution station 6. Then, the heating part 531 presses down the aluminum foil 13 to pre-encapsulate the liquid bladder 2; then the rotating part 200 rotates clockwise again by 45°, and the liquid bladder 2 rotates to the fourth execution station 7, where it is encapsulated. After heating, part 620 is pressed down to seal the aluminum foil 13 onto the liquid bladder 2. Then, the rotating part 200 rotates clockwise by 45° again, and the liquid bladder 2 rotates to the fifth execution station 9. During the rotation, the tail of the aluminum foil 13 is bent by the bending rod 840, and then the tail of the aluminum foil 13 is fixed to the limiting part by the snap fastener 830. Next, the rotating part 200 rotates clockwise by 45° again, and the liquid bladder 2 rotates to the sixth execution station 10. The operator can observe the sealing condition of the liquid bladder 2 at the sixth execution station 10 to facilitate the selection of unsealed products. The qualified liquid bladder 2 is then rotated 45° clockwise again, and the liquid bladder 2 rotates to the seventh execution station 11. The limiting part is then hot-riveted by the heated copper block 930 after being pressed down, thereby completing the processing of the liquid bladder 2. Then, the rotating part 200 rotates 45° clockwise again, and the liquid bladder 2 finally rotates to the finished product execution station 8. The position is adjusted by the material receiving retraction cylinder 751 and the material receiving lifting cylinder 752, and the liquid bladder 2 on the finished product execution station 8 is removed by the material taking part 740 and placed into the storage part 710.
