[0070] See Figure 1 An assembly system for a blood collection needle includes a base 1, a feeding device 2, a handle mounting device 3, a catheter mounting device 4, a coding and calibration device 6, a flow-stopping clamp mounting device 5, a puncture needle seat mounting device 7, a needle core mounting device 8, an anti-clogging detection device 9, a spring mounting device 10, a needle component mounting device 11, a butterfly wing mounting device 12, an accessory mounting device 13, a crimping device 14, several internal dispensing devices 17, and several external gluing devices. The system uses the base 1 as an integrated platform, with the linear conveying of the feeding device 2 connecting the various processing steps. This allows the devices to work together to assemble the handle, catheter, flow-stopping clamp, puncture needle seat, needle core, spring, needle component, and butterfly wing, etc. Furthermore, the base 1 is also equipped with several air blowing devices and an imaging device. The air blowing devices are used to blow air onto the catheter to remove excess glue after internal dispensing to prevent clogging. The imaging devices record the workpiece status at key workstations in real time, visually judging assembly accuracy and improving the assembly pass rate.

[0071] See Figure 1 , Figure 2 and Figure 3The feeding device 2 includes a conveying track 21, a conveying motor, and several fixtures 23 disposed on the conveying track 21. In this embodiment, the conveying track 21 includes two units. The end point of the first conveying track 21 and the starting point of the second conveying track 21 are connected by a fixture transfer device to move the fixtures 23. The conveying motor drives the conveying track 21 to run, driving each fixture 23 to move synchronously, which is used to transport the fixtures 23 of the previous station to the next station. The feeding device 2 is divided into an upper feeding device and a lower unloading device. The upper feeding device is installed above the lower unloading device. The upper feeding device conveys the fixtures 23 along the first direction for assembly. The lower unloading device conveys the fixtures 23 along the second direction to return to the starting position. The second direction is opposite to the first direction. The two ends of the upper feeding device and the lower unloading device transfer the fixtures 23 through the lifting device 15, and so on in a reciprocating cycle.

[0072] Each fixture 23 has several clamping positions for assembling blood collection needles, including a base plate 231, a clamping seat 232, and two clamping plates 233. The bottom of the base plate 231 is mounted on the conveying track 21 via a slider. The clamping seat 232 is centrally mounted on the upper surface of the base plate 231, and its top end has multiple clamping grooves 2310 that match the clamping positions, and they are arranged at intervals along the conveying direction of the conveying track 21. The two clamping plates 233 are symmetrically arranged on both sides of the clamping seat 232, and are bolted vertically to the edge of the base plate 231. The top end of each clamping plate 233 has multiple tube clamping grooves 2320 that correspond to the multiple clamping grooves 2310. The first tube end and the second tube end at both ends of each tube are respectively clamped into the corresponding tube clamping grooves 2320 on both sides.

[0073] The clamping mechanism of the fixture 23 adopts an elastic self-locking design: a clamping block 24 is provided in the clamping groove 2310, and a mounting plate is fixed on each side of the clamping seat 232. The clamping block 24 is hinged to the mounting plates on both sides via a hinge shaft. An elastic element 18 is provided on the inner side of the clamping block 24, which is embedded in the receiving groove of the side wall of the clamping groove 2310. The two ends of the elastic element 18 abut against the bottom of the receiving groove and the corresponding side wall of the clamping block 24, respectively. The side wall of the clamping block 24 away from the elastic element 18 is perpendicular to the side wall of the clamping groove 2310. The wall is recessed to form a clamping groove 27. The outer side of the clamping groove 27 is provided with an inclined surface, and the two inclined surfaces form an outwardly expanding inlet. The handle mounting device 3 is in the first position. When assembling the handle, the handle is slid in along the inclined surface, and the clamping block 24 is rotated to avoid it. After the handle enters the clamping groove 27, the elastic element 18 releases its elastic force to push the clamping block 24 to rotate, and the handle is firmly locked in the clamping groove 27, realizing the automatic centering and elastic clamping of the handle, and ensuring the stability of the workpiece during the conveying and assembly process.

[0074] See Figure 4 and Figure 5The conduit installation device 4 includes a conduit preparation mechanism 41, a conduit feeding mechanism 42, and a conduit pulling mechanism 43. The conduit preparation mechanism 41 includes a conduit hopper 411, a conduit suction assembly 412, and a conduit detection component. Conduits are stacked inside the conduit hopper 411. The conduit detection component is located at the outlet of the conduit hopper 411. It can use weight sensing to monitor the total amount of remaining material, or use infrared sensing to detect the stacking height of the conduits in real time, so as to facilitate timely replenishment of conduits and ensure continuous material supply. The conduit suction assembly 412 is mounted above the outlet on the front side of the conduit hopper 411. It has multiple suction tubes 4121 at its lower part. The multiple suction tubes 4121 are set one-to-one with multiple clamping positions. During operation, the conduit suction assembly 412 drives the multiple suction tubes 4121 to move downward. The suction nozzle end of the suction tube 4121 sucks up the conduit through negative pressure to realize the first stage of conduit material picking.

[0075] The conduit feeding mechanism 42 includes a material preparation seat 421, a main conduit assembly 422, a conduit picking assembly 423, and a conduit threading assembly 424. The material preparation seat 421 is located in front of the conduit hopper 411, and its upper part is provided with several clamping plates with toothed slots. The main conduit assembly 422 includes a main frame body 4221, a main frame module 4222, and a main clamp 4223. The main frame body 4221 is mounted above the material preparation seat 421, and the main frame module 4222 is slidably mounted on the main frame body 4221, with its sliding direction along the horizontal direction. The main frame module 4222 is equipped with multiple main clamps 4223 at its lower part. Each main clamp 4223 corresponds to a different suction tube 4121. The driving component drives the main frame module 4222 to move between a first position and a second position. When in the first position, the main clamp 4223 picks up the guide tube from the corresponding suction tube 4121. When it moves to the second position, the main clamp 4223 moves the guide tube to the material preparation seat 421 and clamps the guide tube into the corresponding toothed slot, thus realizing the second stage of guide tube preparation.

[0076] The pipe-retrieving assembly 423 includes a pipe-retrieving module 4231 and pipe-retrieving clamps 4232. The pipe-retrieving module 4231 is slidably connected to the frame of the main frame module 4222, and its sliding direction is perpendicular to the sliding direction of the main frame module 4222. Multiple pipe-retrieving clamps 4232 are installed at the lower part of the pipe-retrieving module 4231, and each of the multiple pipe-retrieving clamps 4232 corresponds to a multiple main clamp 4223. The pipe-penetrating assembly 424 includes a pipe-penetrating module 4241, a first pipe-penetrating clamp 4242, and a second pipe-penetrating clamp 4243. The pipe-penetrating module 4241 is slidably connected to the frame of the pipe-retrieving module 4231. On the frame, its sliding direction is parallel to the sliding direction of the main frame module 4222. The lower part of the pipe threading module 4241 is equipped with multiple pipe threading clamps 1 4242 and multiple pipe threading clamps 2 4243. The multiple pipe threading clamps 2 4243 are set one-to-one with the multiple pipe threading clamps 1 4242, and the multiple pipe threading clamps 1 4242 are set one-to-one with the multiple pipe taking clamps 4232. The operation of the pipe taking module 4231 drives the pipe taking clamps 4232, pipe threading clamps 1 4242 and pipe threading clamps 2 4243 to move up and down synchronously, so that the three sets of clamps cooperate to hold the guide tube on the material preparation seat 421.

[0077] Pipe threading operation: The drive unit drives the pipe threading module 4241 to move between the third position and the fourth position. When the main frame module 4222 is in the first position, the pipe threading module 4241 needs to be in the third position, that is, the positions of pipe threading clamp 1 4242 and pipe threading clamp 2 4243 are far away from the pipe picking clamp 4232. The pipe picking module 4231 drives the pipe picking clamp 4232, pipe threading clamp 1 4242 and pipe threading clamp 2 4243 to move down synchronously and approach the material preparation seat 421, and then lifts it after clamping the guide tube. The catheterization module 4241 moves to the fourth position, and the catheterization clamp 1 4242 and catheterization clamp 2 4243 move closer to the catheter removal clamp 4232. The catheter naturally droops due to gravity, forming a U-shaped bend. After the main frame module 4222 moves to the second position, the catheterization module 4241 moves to the third position. During this process, the catheterization clamp 2 4243 pulls the first end of the catheter into the handle and then releases it. The catheterization clamp 1 4242 continues to push the catheter until the first end of the catheter passes through the handle and is exposed, thus completing the catheterization operation.

[0078] The tubing pulling mechanism 43 includes a traction seat 431, a tubing pulling module 432, and a tubing pulling clamp 433. The traction seat 431 is located on the side of the tubing feeding mechanism 42 away from the tubing preparation mechanism 41. The tubing pulling module 432 is slidably connected to the upper end of the traction seat 431. The tubing pulling clamp 433 is installed at the front end of the tubing pulling module 432. The driving component drives the tubing pulling module 432 to move back and forth. The tubing pulling module 432 drives the tubing pulling clamp 433 to move forward. The tubing pulling clamp 433 approaches the clamping fixture 23, which clamps the exposed first tube end. The tubing pulling module 432 drives the tubing pulling clamp 433 to move backward until the tubing is pulled to the designated position, completing the assembly of the tubing and the handle.

[0079] The inkjet calibration device 6 is located at the next station after the conduit installation device 4. In this embodiment, the inkjet calibration device 6 includes a first inkjet mechanism and a second inkjet mechanism. The two inkjet mechanisms are respectively mounted on the symmetrical sides of the conveying track 21 and spray identification codes onto the first and second ends of the conduit. The two identification codes are detected by the identification device to calibrate the position of the conduit and reduce the deviation.

[0080] See Figure 7 and Figure 8 The flow-stop clamp installation device 5 includes a flow-stop clamp feeding mechanism 51, a flow-stop clamp positioning mechanism 52, a flow-stop clamp flipping mechanism 53, and a flow-stop clamp assembly mechanism 54. The flow-stop clamp feeding mechanism 51 includes a flow-stop clamp vibrating plate 511, a first feeding platform 512, and a second feeding platform 513. The vibrating plate is existing technology and will not be described in detail here. It is used to output the flow-stop clamp workpiece. The first feeding platform 512 and the second feeding platform 513 each have several matching material channels on their upper parts. The inlet of the material channel of the first feeding platform 512 is connected to the output end of the flow-stop clamp vibrating plate 511. The flow-stop clamp vibrating plate 511 feeds the flow-stop clamp to the first feeding platform 512. The flow-stop clamps are fed one by one along the material channels of the first feeding platform 512 to the flow-stop clamp positioning mechanism 52. The flow-stop clamps are fed one by one along the material channels of the second feeding platform 513 to the flow-stop clamp flipping mechanism 53.

[0081] The flow-stopping clamp positioning mechanism 52 is located between the first feeding platform 512 and the second feeding platform 513. It includes a moving part 521, grippers 522, a flow-stopping clamping platform 523, and a hole position sensor 524. The moving part 521 is mounted above the discharge port of the first feeding platform 512. Multiple grippers 522 are rotatably mounted on the lower part of the moving part 521, each gripper corresponding to a different material channel of the first feeding platform 512. The flow-stopping clamping platform 523 is attached to the discharge port of the first feeding platform 512, and each material channel discharge port has a flow-stopping clamp groove, which can engage a flow-stopping clamp. The flow-stopping clamp has an eccentrically positioned clamping hole. The hole position sensor 524 is eccentrically set at the bottom of the corresponding stop clamp slot. When the probe end is aligned with the clamp hole, the stop clamp is judged to be in the correct position. If the probe end is blocked by the stop clamp, the stop clamp is judged to be in the wrong position. The system transmits a signal to trigger the correction operation. The moving part 521 drives the gripper 522 to hold the stop clamp. The gripper 522 will rotate 180° to change the orientation of the wrong stop clamp, while the correct stop clamp remains in its original position, so that all stop clamps are in the same position. The moving part 521 moves to the feeding platform 513, and the gripper 522 puts the stop clamp into the feed port of the feeding platform 513 to ensure subsequent assembly and use.

[0082] See Figure 8 and Figure 9The flow stop clamp flipping mechanism 53 is rotatably mounted on the discharge end of the feeding platform 2 513. The flow stop clamp flipping mechanism 53 is provided with several card slots 26, which correspond one-to-one with several material channels of the feeding platform 2 513. The card slots 26 can be inserted into a flow stop clamp output from the corresponding material channel. Since the flow stop clamps have a uniform posture, the clamping holes are exposed in the card slots 26. The flow stop clamp flipping mechanism 53 rotates and drives the flow stop clamps to flip to a vertical posture.

[0083] The flow stop clamp assembly mechanism 54 includes a frame 541, a clamping assembly 542, a mounting assembly 543, and a mounting assembly 544. The frame 541 is mounted above the flow stop clamp flipping mechanism 53. The clamping assembly 542 is slidably mounted on the frame 541, and its sliding direction is set back and forth in the horizontal direction. The lower part of the clamping assembly 542 is provided with a number of pins 5421, which correspond one-to-one with a number of card slots 26. The clamping assembly 542 is driven to move by a driving component. The clamping assembly 542 drives each clamping pin to pass through the clamping hole of the flow stop clamp and remove the clamping pin from the card slot 26.

[0084] Mounting component 1 543 is mounted on frame 1 541, and mounting component 2 544 slides on frame 1 541. Mounting component 2 544 is located outside mounting component 1 543. The two mounting components are engaged with the guide tubes on both sides of the corresponding clamping plate 233. The guide tube is pulled from the clamping groove 2320 to the set height, and the end of the guide tube is aligned with the clamping hole of the flow stop clamp. The clamping component 542 moves the flow stop clamp closer to the guide tube, and the front end of the ejector pin 5421 is inserted into the tube hole of the guide tube for initial positioning. At this time, mounting component 1 543 releases the guide tube, and the clamping component 542 pushes all the flow stop clamps along the corresponding ejector pin 5421 to be fitted onto the guide tube through the push plate structure 5422. The clamping component 542 withdraws, and then mounting component 1 543 clamps the guide tube again. The two mounting components work together to descend and press the guide tube into the clamping groove 2320. At this time, the flow stop clamp is between the clamping plate 233 and the clamping seat 232, and the assembly is completed.

[0085] See Figure 1 , Figure 17 and Figure 18The external adhesive application device is located at the next station after the flow-stop clamp installation device 5. It is used to apply adhesive to the outer peripheral wall of the first end of the conduit to facilitate the subsequent installation of the puncture needle seat. The internal adhesive dispensing device 17 is located on the opposite side of the external adhesive application device. It includes a second pressing mechanism 171 and an internal dispensing mechanism 172. The second pressing mechanism 171 is used to clamp and position the second end of the conduit. The internal dispensing mechanism 172 includes an internal dispensing frame 1721, an internal dispensing assembly 1722, and a dispensing insert 1723. The inner dispensing assembly 1722 is slidably disposed on the upper end of the inner dispensing frame 1721, and its sliding direction is set along the front and back. The inner dispensing assembly 1722 is provided with multiple dispensing rods 1723 near the front end of the pressure fixing mechanism 171. Each of the multiple dispensing rods 1723 corresponds to a multiple conduit. The driving component drives the inner dispensing assembly 1722 to move, and the inner dispensing assembly 1722 drives the end of each dispensing rod 1723 to insert into the first tube end of the corresponding conduit, dispensing adhesive onto the inner wall of the conduit and then withdrawing.

[0086] The puncture needle hub mounting device 7 is located at the next station after the external adhesive device, and it is used to bond the puncture needle hub to the first end of the catheter. The needle core mounting device 8 is located at the next station after the internal adhesive device 17, and it is used to insert the needle core and bond it to the second end of the catheter.

[0087] See Figure 10 The anti-blocking detection device 9 is located at the next station next to the puncture needle seat mounting device 7. It includes a pressing mechanism 91 and an air blowing mechanism 92. The pressing mechanism 91 is located in front of the air blowing mechanism 92, close to the clamping fixture 23, and is used to clamp and position the puncture needle seat. The air blowing mechanism 92 includes an air blowing seat 921, a displacement drive 922, an air blowing slide 923, and air blowing nozzles 924. The air blowing slide 923 is slidably connected to the upper end of the air blowing seat 921, and its sliding direction is set horizontally back and forth. Multiple air blowing nozzles 924 are installed at the front end of the air blowing slide 923. Multiple catheters are configured one-to-one. The displacement drive 922 is located on the side of the air blowing slide 923 away from the air blowing head 924. It is installed on the air blowing seat 921 and its output end is connected to the air blowing slide 923. The displacement drive 922 drives the air blowing slide 923 to move forward, so that multiple air blowing heads 924 abut against the corresponding puncture needle seat to blow air. The air pressure changes are monitored in real time by the air pressure detection device. If the air pressure continues to rise to the threshold (indicating that the needle core is well sealed and the catheter is unobstructed), or if the air pressure fluctuates abnormally (indicating catheter leakage), an alarm is triggered immediately, and the needle core needs to be re-glued and reinstalled.

[0088] See Figure 11 and Figure 12The spring mounting device 10 includes a spring feeding mechanism 101, a spring preparation mechanism 102, a limiting mechanism, and a spring assembly mechanism 104.

One end of each spring conveying tube 1012 is connected to the spring vibrating plate 1011, and the other end is connected to the spring preparation mechanism 102. The springs output from the spring vibrating plate 1011 are conveyed one by one along the spring conveying tubes 1012. An airflow-assisted method is used to generate directional airflow using compressed gas to push the springs to move, so as to avoid the springs from tangling and blocking.

[0089] The spring preparation mechanism 102 includes a preparation rack 1021, a top-feeding assembly 1022, and a spring fixing clamp 1023. The top of the preparation rack 1021 has several spring grooves 19, which correspond one-to-one with several spring conveying pipes 1012 and are connected to the outlet of the spring conveying pipes 1012. Each spring groove 19 can be prepared with one spring. The top-feeding assembly 1022 is slidably installed below the preparation rack 1021 and can move in the vertical direction. The top of the top-feeding assembly 1022 is provided with a spring fixing clamp 1023 corresponding to each spring groove 19. The spring fixing clamp 1023 is preferably a two-finger cylinder claw, used to clamp the spring in the spring groove 19. When the top-feeding assembly 1022 drives the spring fixing clamp 1023 to move upward, the spring is exposed in the spring groove 19 to provide a single spring.

[0090] The spring assembly mechanism 104 includes an outer frame 1041, an assembly 1042, and spring sleeve clamps 1043. The outer frame 1041 is mounted above the material preparation rack 1021.

The lower part of the assembly 1042 is provided with several spring sleeve clamps 1043, which correspond one-to-one with several spring fixed clamps 1023. The spring sleeve clamps 1043 are preferably three-finger cylinder clamps to offset the two-finger cylinder clamps of the spring fixed clamps 1023. The assembly 1042 drives the spring sleeve clamps 1043 to move downward, and the spring sleeve clamps 1043 clamp the springs. During assembly, the assembly 1042 drives the spring sleeve clamps 1043 forward to mount the springs onto the needle core end. The needle core clamp 1032 releases the needle core and retracts. The assembly 1042 continues to move until the assembly is complete.

[0091] The needle mounting device 11 is located on one side of the first end of the catheter during assembly. Two needle mounting devices 11 are provided, namely the puncture needle mounting device 111 and the threaded puncture needle mounting device 112. After the spring is installed, the puncture needle mounting device 111 can install the puncture needle into the puncture needle seat. The threaded puncture needle mounting device 112 is installed on the opposite side of the butterfly blade mounting device 12 and can install the threaded puncture needle into the puncture needle seat. The puncture needle seat can only install one of the puncture needle and the threaded puncture needle according to actual production needs.

[0093] The butterfly wing detection mechanism 122 includes a detection frame 1221 and detection terminals 1222. The detection frame 1221 is supported by the discharge port of the feeding table 1212. The upper end of the detection frame 1221 has multiple feeding slots 20 for accommodating butterfly wings. Each feeding slot 20 is provided with a corresponding detection terminal 1222. The detection terminal 1222 shown in this embodiment includes two endpoints. The butterfly wing has two wings, and the curvature of one edge of the wing is greater than that of the other edge. After the butterfly wing touches the wall of the feeding slot 20, if the curved edges of the two wings do not touch the two endpoints, it means that the butterfly wing is in the correct posture. When the edges of the two wings touch the two endpoints, the placement of the butterfly wing is determined to be in an incorrect posture. At this time, the system will receive a signal and trigger an alarm.

[0094] The butterfly wing assembly mechanism 123 includes an assembly frame 1231, an assembly component 1232, and butterfly wing clamps 1233.

The assembly component 1232 is driven by a driving component to move in the fifth and sixth positions. The assembly component 1232 moves between positions; when it is in the fifth position, it is located above the inspection frame 1221. The assembly component 1232 drives the butterfly blade clamp 1233 to clamp the butterfly blade that has been inspected in the corresponding material feeding slot 20; when the assembly component 1232 moves to the sixth position, the needle core and the guide tube are fixed and positioned by other clamps. The assembly component 1232 drives the butterfly blade clamp 1233 to continue forward. Using the original snap-fit ​​structure between the butterfly blade and the needle core, the butterfly blade is accurately snapped onto the needle core, thereby completing the assembly.

The first crimping assembly 1412 pushes the butterfly wing and the needle core to apply pressure, thereby crimping and assembling the butterfly wing and the guide tube into a whole. The needle core is limited between the butterfly wing and the guide tube, thus completing the crimping assembly.

[0099] The pressing mechanism 144 is movably mounted on the lifting frame 1421. A pressing component 1441 is located at the lower part of the pressing mechanism 144, with clearance provided at the position corresponding to the clamping plate 233 to avoid interference with the clamping plate 233. During operation, the pressing mechanism 144 drives the pressing component 1441 downwards, pressing the two points of the component until it is engaged within the clamping groove 2320, completing the assembly and fixing of the component.

[0100] The specific work process of this plan is as follows:

[0101] This technical solution integrates multiple automated devices. The linear conveying of the feeding device 2 enables process connection. Multiple sets of fixtures 23 flow along a preset path. The handle installation device 3 first clamps the handle into the clamping position. The catheter installation device 4 inserts the catheter into the handle. The inkjet marking device 6 prints markings on both ends of the catheter to determine the length of the guide wire. The flow stop clamp installation device 5 assembles the flow stop clamp onto the catheter. Then, the puncture needle seat and the needle core are respectively bonded to both ends of the catheter. The anti-blocking detection device 9 blows air onto the puncture needle seat to verify the seal. Then, the spring, needle, butterfly blade, and accessories are installed in sequence. Finally, the crimping device 14 crimps and locks the butterfly blade and the handle to secure the needle core and the spring between them, completing the assembly. This integrated system eliminates process fragmentation through continuous flow operation and improves assembly efficiency through multi-station parallel processing, realizing fully automated production of blood collection needles.
