Description

Technical Field

[0001] This invention relates to the field of medical device processing equipment, specifically to a fully automated production line for processing intravenous needles. Background Technology

[0002] Traditionally, intravenous needles are assembled by connecting the two ends of a flexible tube to the needle and the connector. During assembly, the flexible tube is placed on a fixture, which then transports it to the needle connector for insertion. The fixture then transports the flexible tube to the connector for insertion. A gas test is then performed to check for blockages after assembly. When intravenous needles need to be individually packaged, a cap is required on the connector to prevent dust from entering the needle. However, the production line described above does not include caps on the intravenous needles. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes a fully automated production line for intravenous needles, which facilitates the application of a cap to the connector of the intravenous needle while simultaneously improving the processing efficiency of the needles.

[0004] To achieve the above objectives, the present invention provides a fully automated production line for intravenous needles, comprising a tubing conveying mechanism, a first gluing mechanism, a second gluing mechanism, a needle docking mechanism, a connector docking mechanism, and a capping mechanism, wherein the tubing conveying mechanism is sequentially connected to the first gluing mechanism, the needle docking mechanism, the second gluing mechanism, the connector docking mechanism, and the capping mechanism, and all of the above mechanisms are mounted on a table. The hose delivery mechanism includes fixtures and a circulating delivery assembly. Multiple sets of fixtures are arranged at equal intervals on the circulating delivery assembly, and multiple hoses are placed side by side on each fixture. The first gluing mechanism and the second gluing mechanism are located on both sides of the hose conveying mechanism. The first gluing mechanism and the second gluing mechanism are located one station before the needle docking mechanism and the connector docking mechanism, respectively. A capping mechanism is provided on the side of the end of the hose conveying mechanism. The capping mechanism includes a cap sorting component, a cap linear track, a temporary storage seat, and a rotary three-jaw chuck. The cap sorting component is connected to and connected to the cap linear track. A temporary storage seat that can be moved is connected to the end of the cap linear track. Multiple cap embedding slots that connect to multiple cap linear tracks are opened on the temporary storage seat. The cap linear track and the cap embedding slots are misaligned by moving the temporary storage seat. A rotary three-jaw chuck is provided above the cap embedding slot and is vertically opposite to the cap embedding slot. Multiple rotary three-jaw chucks are installed on the same rotating component, which is installed on the same set of translation components.

[0005] Preferably, a detection component is installed in each cap embedding slot to detect whether a cap is present in the slot. Multiple rotating three-jaw chucks arranged side by side are mounted on the same mounting plate through a rotational engagement. A synchronous wheel is mounted on each rotating three-jaw chuck. Multiple stepper motors driving the synchronous wheels are mounted on the mounting plate. The synchronous wheels on the stepper motors and the synchronous wheels on the rotating three-jaw chucks are driven by synchronous belts. The rotating component is a turntable. The two sides of the mounting plate are mounted on the turntable. A translation component is mounted on the turntable. The translation component includes a mounting frame and a guide column. The mounting frame is mounted on the table surface. The turntable and the mounting frame are rotatably engaged. A cam is mounted on the turntable. A cylinder A is set between the cam and the mounting frame. The rotation of the turntable is achieved by the extension and retraction of cylinder A. A guide column is mounted on the turntable. The guide column passes through the mounting plate, and the mounting plate moves on the guide column. A cylinder B is set between the mounting plate and the turntable. The translation of the mounting plate is achieved by the extension and retraction of cylinder B.

[0006] Preferably, a clamping assembly for clamping the end of the hose is provided between the first gluing mechanism, the second gluing mechanism, the needle docking mechanism, the connector docking mechanism, the capping mechanism and the hose delivery mechanism. The clamping assembly includes an upper clamping mold and a lower clamping mold. Telescopic cylinders are provided on both the upper and lower clamping molds. The upper and lower clamping molds are closed by telescopic cylinders. A groove for clamping the hose and connector is provided between the upper and lower clamping molds.

[0007] Preferably, a testing mechanism is provided between the capping mechanism and the connector docking mechanism. The testing mechanism includes a testing head and a testing lifting assembly. Multiple testing heads are installed on the same testing plate. The testing lifting assembly is installed on the testing plate to move the testing plate. Two sets of vertically lifting clamps are provided on one side of the testing plate. The two sets of clamps are located at both ends of the hose and clamp the needle and the connector respectively. A groove is opened on the opposite surface of the clamps on the clamping side of the connector to fit against the outer wall of the connector. The testing head abuts against the outer wall of the clamp and docks with the connector. The testing head is connected to the air pump. A pressure detection module is provided inside the testing head. The clamps that clamp the needle have a groove for clamping the needle.

[0008] Preferably, the test head includes a rigid gas tube, a rubber gas inlet, and a sliding sleeve. The sliding sleeve is fitted onto the rigid gas tube and fixed to the test plate. A frustum-shaped rubber gas inlet is fixed to the end of the rigid gas tube facing the connector. The rubber gas inlet rests against the clamp and communicates with the connector. A buffer spring is fitted onto the rigid pipe, with its two ends fixed to the test plate and the rigid pipe, respectively. A baffle is installed inside the rigid gas tube, and vent holes are opened on the outer walls of both sides of the baffle. An elongated connecting hole is opened on the inner wall of the sliding sleeve. When the rigid pipe is misaligned due to the rubber gas inlet pushing against the clamp, the two vent holes of the rigid pipe communicate with the connecting hole. When the rubber gas inlet moves away from the clamp, the two vent holes of the rigid pipe are misaligned with the connecting hole, thus stopping the gas supply.

[0009] Preferably, the first gluing mechanism includes a gluing swing plate, a gluing rod, a rotating module, and a gluing displacement assembly. The gluing rod is mounted on the gluing swing plate and is rotatably connected to the gluing swing plate. A gear is mounted at one end of each gluing rod. A rotating module is provided above the gluing swing plate. The rotating module is a rack driven by a cylinder C. The rack meshes with multiple gears. The lower part of the gluing swing plate is hinged to the gluing displacement assembly. A swing cylinder is provided between the gluing swing plate and the gluing displacement assembly. The swing of the gluing swing plate is achieved by the extension and retraction of the swing cylinder. A first glue box is provided below the gluing swing plate. The rotation of the gluing swing plate extends one end of the gluing rod into the first glue box.

[0010] Preferably, the second glue application mechanism includes a glue application translation component and glue application clamping arms. Multiple sets of glue application clamping arms arranged side by side are installed on the glue application translation component. Each set of glue application clamping arms consists of two parallel arms, and a notch is provided on the inner side of the two glue application clamping arms to allow the hose to pass. A sponge layer is provided in the notch. A second glue box is provided below the glue application clamping arms. A lifting component is provided at the bottom of the second glue box and on the table surface. The second glue box is gradually lifted and lowered by lifting.

[0011] Preferably, the needle docking mechanism includes a needle sorting component and a needle clamping docking component. The needle sorting component is a vibratory sorting device. A linear needle conveying track is connected to the outlet of the vibratory sorting device, and a needle clamping docking component is connected to the end of the linear needle conveying track. The needle clamping docking component includes a telescopic cylinder Z and a finger cylinder M. A fixed plate is mounted on the table via a sliding fit. The telescopic cylinder Z is positioned between the fixed plate and the table. The fixed plate slides left and right by the extension and retraction of the telescopic cylinder Z. Multiple finger cylinders M are fixed side by side on the right end face of the fixed plate. The clamping mouth of the finger cylinder M is connected to the linear needle conveying track. When the needle moves to the clamping mouth of the finger cylinder M, the finger cylinder M engages with the needle. The head is clamped, and the telescopic cylinder Z transports the needle to the fixture and mates it with the end of the tubing. The finger cylinder M clamps the needle and transports it to the tubing, achieving needle-to-tubing docking. The docking mechanism includes a docking sorting component, a docking linear conveying track, a docking clamping component, a docking lifting component, and a docking assembly. At the end of the docking linear conveying track, there is a docking clamping component that can move horizontally. Below the docking clamping component, there is a docking lifting component that can be raised and lowered. On one side of the tubing, there is a docking assembly. When the docking lifting component descends to the point where the docking assembly is coaxial with the tubing, the docking assembly mates the docking component with the tubing.

[0012] Preferably, the connector lifting assembly is equipped with multiple lifting modules arranged side by side, each lifting module being a V-shaped placement groove. The connector docking assembly is a lifting rod that is extended and retracted by a cylinder D. The lifting rod extends into the connector and fits against the inner wall of the connector, thereby connecting the connector to the hose via the lifting rod. Compared with the prior art, the advantages of the present invention are as follows: The automatic assembly of intravenous needles is achieved by covering the connector of the intravenous needle with a cap, which also improves the processing efficiency of intravenous needles. Perform an intravenous puncture between capping processes to prevent blockage of the finished product. Attached Figure Description

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] like Figure 1-14 The fully automated production line for intravenous needles includes a tubing conveying mechanism 1, a first gluing mechanism 4, a second gluing mechanism 13, a needle docking mechanism 18, a connector docking mechanism 22, and a capping mechanism 32. The tubing conveying mechanism 1 is connected in sequence to the first gluing mechanism 4, the needle docking mechanism 18, the second gluing mechanism 13, the connector docking mechanism 22, and the capping mechanism 32. All of the above mechanisms are installed on a table. The hose conveying mechanism 1 includes fixtures 2 and a circulating conveying assembly 3. Multiple sets of equally spaced fixtures 2 (fixtures 2 are flat plates, with upward-extending clamping plates fixed to their top surfaces at both ends by bolts; multiple parallel V-grooves are cut on the clamping plates; the ends of the hose are placed within the V-grooves of the clamping plates, while the ends of the hose protrude from the clamping plates; the V-grooves limit the position of the hose, preventing it from rolling during conveying) are used. The rotating conveying mechanism is a chain driven by sprockets. The bottom of fixtures 2 is connected via... Bolts are installed on the chain, and the sprocket is installed on the table through bearings and bearing seats. The sprocket is driven by a motor, thus realizing the movement of the jig 2. Auxiliary brackets 63 are set on both sides of the two chains (the auxiliary brackets 63 are long strips, and the two ends of the auxiliary brackets 63 are fixed with columns by welding. The bottom of the columns is fixed on the table. The outer side of the chain contacts the inner wall of the auxiliary brackets 63, and the position of the chain is limited by the auxiliary brackets 63). The top of the auxiliary brackets 63 contacts the bottom of the jig 2, and the auxiliary brackets 63 assist the jig 2 in parallel transport. The first gluing mechanism 4 is located to the left of the hose conveying mechanism 1, and the second gluing mechanism 13 is located to the right of the hose conveying mechanism 1. The fixture 2 is sequentially connected to the first gluing mechanism 4 and the second gluing mechanism 13 via the circulating conveying assembly 3. The first gluing mechanism 4 is located at the first station of the hose conveying mechanism 1, and the second gluing mechanism 13 is located to the right of the second station of the hose conveying mechanism 1. The first gluing mechanism 4 and the second gluing mechanism 13 are respectively located at the station before the needle docking mechanism 18 (to the left of the second station) and the connector docking mechanism 22 (the third station). Before the tubing is connected to the needle, the inner wall of one end of the tubing is coated with adhesive by the first adhesive coating mechanism 4. The circulating conveying component 3 transports the coated tubing to the needle docking mechanism 18 to achieve the docking of the needle and the tubing. A second adhesive coating mechanism 13 is set opposite the needle docking mechanism 18. When the needle is docked, the second adhesive coating mechanism 13 applies adhesive to the outer wall of the other end of the tubing. Then the fixture 2 transports the tubing to the connector docking mechanism 22 (third station) to dock the connector and the tubing. This completes the docking of the needle, tubing and connector.

[0030] A clamping assembly 46 for clamping the end of the hose is provided between the first gluing mechanism 4, the second gluing mechanism 13, the needle docking mechanism 18, the connector docking mechanism 22, the capping mechanism 32, and the hose delivery mechanism 1. The clamping assembly 46 includes an upper clamping mold 47 and a lower clamping mold 48 (the upper clamping mold 47 and the lower clamping mold 48 are arranged vertically opposite each other, and both the upper clamping mold 47 and the lower clamping mold 48 are made of sheet metal. Multiple V-grooves arranged side by side are opened on the top surface of the lower clamping mold 48 (multiple V-grooves form a serrated groove), and multiple grooves are fixed on the bottom of the upper clamping mold 47). The pressure block (the protruding pressure block forms a serrated groove) fits against the inner wall of the V-groove. Circular grooves are formed at the bottom of the pressure block of the upper clamping mold 47 and the bottom of the V-groove of the lower clamping module, which clamp the hose, needle, and connector. Telescopic cylinders 49 are installed on both the upper clamping mold 47 and the lower clamping mold 48. Specifically, telescopic cylinders 49X are installed between the bottom of the lower clamping module and the table surface by bolts. Multiple inverted L-shaped brackets are bolted to the table surface. Two inverted L-shaped brackets are positioned above each upper clamping mold 47. The inverted L-shaped brackets and the upper clamping mold 47... A telescopic cylinder 49Y is fixed in place by bolts. The telescopic cylinders 49X and 49Y together allow the upper clamping mold 47 and lower clamping mold 48 to close and open, clamping or releasing the hose or connector. When applying adhesive to the hose and the first adhesive application mechanism 4, the hose protrudes from the fixture 2 by a certain length, causing one end of the hose to droop downwards. This affects the adhesive application by the first adhesive application mechanism 4. The upper clamping mold 47 and lower clamping mold 48 clamp the protruding end of the hose from the fixture 2, thus preventing the hose from... The end hangs down to ensure that the first gluing mechanism 4 is coaxial with the hose, thus ensuring the gluing effect. The needle and hose docking, the second gluing mechanism 13 gluing, the connector and hose connector, and the air testing mechanism 50 all use the upper clamping mold 47 and the lower clamping mold 48 for clamping and alignment. When the connector is capped, the end of the connector needs to be clamped to prevent the connector (rigid) and the hose from rotating relative to each other when capping. After the upper clamping mold 47 and the lower clamping mold 48 clamp the connector, the rotation of the connector is restricted. The cap is placed on the connector to complete the assembly.

[0031] The first gluing mechanism 4 includes a gluing swing plate, gluing rods 6, a rotating module 8, and a gluing displacement assembly 11. The gluing rods 6 are mounted on the gluing swing plate via bearings (i.e., multiple gluing rods 6 pass through the gluing swing plate, and the gluing rods 6 are connected to the gluing swing plate via bearings, thus enabling the rotation of the gluing rods 6). A gear 7 is mounted on one end of each gluing rod 6 that passes through the gluing swing plate via a flat key. A cylindrical brush is mounted on the other end of each gluing rod 6. A rotating module 8 is positioned above the gluing swing plate to rotate... Module 8 is a rack 9 driven by cylinder C. The rack 9 meshes with multiple gears 7 (the cylinder body of cylinder C is bolted to the adhesive application swing plate; the rack 9 is welded to the piston rod of cylinder C; a groove is welded to the back of the adhesive application swing plate, and the rack 9 moves within the groove). When the rack 9 moves, the multiple gears 7 rotate synchronously, thus achieving synchronous adhesive application. The bottom of the adhesive application swing plate is hinged to the adhesive application displacement assembly 11, enabling the swing of the adhesive application swing plate. A swing cylinder 10 is hinged between the gluing swing plate and the gluing displacement assembly 11. The extension and retraction of the swing cylinder 10 achieves a 90° swing of the gluing swing plate. The gluing displacement assembly 11 consists of a flat plate and a displacement cylinder. The flat plate slides on the table surface (two parallel horizontal rods are fixed to the table surface with bolts, passing through the flat plate, allowing the plate to move left and right on the horizontal rods). A displacement cylinder is bolted between the back of the flat plate and the table surface. The lifting action of the displacement cylinder... The flat plate moves closer to the fixture 2, so that the glue-applying rod 6 extends into the inner wall of the left end of the hose. By rotating, glue is evenly applied to the inner wall of the hose. The first glue box 12 is installed on the table below the glue-applying swing plate by bolts. By rotating the glue-applying swing plate, one end of the glue-applying rod 6 extends into the first glue box 12, so that glue adheres to the glue-applying rod 6. Then, the glue-applying swing plate swings upward to the horizontal. The upper frame translation component 40 pushes the glue-applying swing plate to move towards the fixture 2, and the glue-applying rod 6 extends into the end of the hose.

[0032] The needle docking mechanism 18 includes a needle sorting component 19 and a needle clamping docking component 20. The needle sorting component 19 is a vibratory sorting device. A linear needle conveying track is connected to the outlet of the vibratory sorting device. The needle clamping docking component 20 is connected to the end of the linear needle conveying track. The needle clamping docking component 20 consists of a telescopic cylinder 49Z and a finger cylinder M. Two parallel horizontal rods are fixed to the table surface by bolts. The horizontal rods pass through the same fixed plate. The telescopic cylinder 49Z is fixed between the fixed plate and the table surface by bolts. The fixed plate extends and retracts along the horizontal rods. The cylinder 49Z slides left and right during telescopic movement. Multiple finger cylinders M are fixed side by side on the right end of the fixed plate by bolts. The clamping port of the finger cylinder M is connected to the needle linear conveying track. When the needle moves to the clamping port of the finger cylinder M, the finger cylinder M clamps the needle. The telescopic cylinder 49Z conveys the needle to the fixture 2 and connects it to the end of the tubing (before connection, the upper clamping mold 47 and the lower clamping mold 48 clamp the end of the tubing to ensure that the tubing and the needle are coaxial). The needle is clamped by the telescopic clamping arm 21, which clamps the needle and conveys it to the tubing to achieve the connection between the needle and the tubing.

[0033] The second gluing mechanism 13 includes a gluing translation component 4014 and gluing clamping arms 15. Multiple sets of gluing clamping arms 15 are installed side-by-side on the gluing translation component 4014. Each set of gluing clamping arms 15 consists of two opposing gluing clamping arms 15. Two translation plates (the two translation plates are arranged vertically, with multiple sets of oblong holes on the bottom translation plate) are bolted to the two gluing clamping arms 15 on each set. One gluing clamping arm 15 from each set is fixed to the bottom translation plate by bolts, and the other gluing head passes through the oblong holes on the translation plate. The hole and the upper translation plate are fixed by bolts. The relative movement of the two translation plates realizes the closing and opening of the glue-applying clamp arm 15. A clamping cylinder is fixed between the two translation plates by bolts. The piston rod and cylinder body of the clamping cylinder are respectively fixed to the two translation plates by bolts. The relative movement of the two translation plates is realized by the clamping cylinder. The translation plate near the glue-applying translation assembly 4014 is fixed to the glue-applying translation assembly 4014 by bolts. The two translation plates slide in cooperation (a straight rod is fixed on one translation plate, and a sliding seat is sleeved on the straight rod. The sliding seat is installed on the other translation plate by bolts). On an outer sliding plate (to achieve sliding fit between sliding plates), each set of adhesive clamping arms 15 consists of two parallel adhesive clamping arms 15, with semi-circular notches on the inner side of the two adhesive clamping arms 15 to allow for the movement of the hose. When the two upper clamping arms are closed, the adhesive clamping arms 15 contact the outer wall of the hose. A semi-circular sponge layer 16 is pasted inside each semi-circular notch. A second glue box 17 is set on the table below the adhesive clamping arms 15. A lifting assembly is set at the bottom of the second glue box 17. The lifting assembly is a cylinder. The cylinder body of the lifting assembly is fixed to the table by bolts, and the piston rod of the lifting assembly is fixed to the... At the bottom of the second glue box 17, the second glue box 17 is raised and lowered by the extension and retraction of the cylinder. When working, the second glue box 17 rises, and the sponge layer 16 on the glue-applying clamp arm 15 is immersed in the second glue box 17. The sponge layer 16 absorbs glue. Then the second glue box 17 falls, and the glue-applying translation component 4014 moves the glue-applying clamp arm 15 toward the fixture 2. In this way, the end of the hose is located between the glue-applying clamp arms 15. Then the glue-applying clamp arms 15 close and the hose is located in the circular notch of the clamp arm. Then the glue-applying translation component 4014 returns to its original position. In this way, the glue-applying clamp arm 15 applies glue to the outer wall of one end of the hose.

[0034] The connector docking mechanism 22 includes a connector sorting component 23, a connector linear conveyor track 24, a connector clamping component 25, a connector lifting component 26, and a connector docking component 30. The connector sorting component 23 is also a vibratory sorting device. The outlet of the connector sorting component 23 is connected to the connector linear conveyor track 24. At the end of the connector linear conveyor track 24, there is a connector clamping component 25 that can move left and right. (The connector clamping component 25 consists of multiple finger cylinders N arranged side by side. The multiple finger cylinders N are bolted to the same connecting plate. Two parallel horizontal rods are installed on the table by bolting.) The guide rod passes through the connecting plate, which slides left and right on the transverse rod. A cylinder is installed between the connecting plate and the table surface by bolts, which enables the connecting plate and the finger cylinder N to move left and right. When the connector moves to the end of the connector linear conveyor track 24, the finger cylinder N simultaneously engages with the end of the connector linear conveyor track 24, and the finger cylinder N directly clamps the connector and moves it to the right. Below the connector clamping assembly 25 after it moves to the right, there is a liftable connector lifting assembly 26 (the connector lifting assembly 26 is located above the table surface, and the table surface and the bottom of the connector lifting assembly 26 are fastened by bolts). Equipped with a lifting cylinder (thus raising and lowering the connector lifting assembly 26), a connector docking assembly 30 is located on the left side of the platform of the hose (the connector docking assembly 30 is located between the connector lifting assembly 26 and the end of the connector linear conveying track 24, wherein the connector docking assembly 30 is lower than the connector linear conveying track 24). When the connector lifting assembly 26 descends and becomes coaxial with the connector docking assembly 30 and the hose, the connector docking assembly 30 pushes the connector to the right to dock with the hose. During operation, when the connector linear conveying track 24 conveys the connector to the end, the connector clamping assembly 25 clamps the connector. Then, the connector clamping assembly 25 moves to the right above the connector lifting assembly 26. The connector lifting assembly 26 rises to support the connector, and the finger cylinder N on the connector clamping assembly 25 is released. The connector clamping assembly 25 moves to the left to return to its original position and clamps the connector. At the same time, the connector lifting assembly 26 descends to make the connector coaxial with the hose. The connector docking assembly 30 extends into the connector and pushes the connector to the right to dock with the hose. When the connector docking assembly 30 extends into the connector, the connector docking assembly 30 moves to the left to return to its original position, and at the same time, the connector lifting assembly 26 rises.

[0035] Multiple lifting modules 27 are installed side-by-side on the top surface of the connector lifting assembly 26 by bolts. Each lifting module 27 is a V-shaped placement groove 28. Multiple V-shaped placement grooves 28 are installed side-by-side on the lifting plate by bolts. A lifting cylinder is installed between the lifting plate and the table surface by bolts. The lifting cylinder completes the lifting and lowering of the lifting plate. The connector docking assembly 30 is a lifting rod 31 that is telescopically operated by a cylinder (multiple lifting rods 31 are installed on the left side of the same plate by bolts. A cylinder D is installed between the plate and the table surface by bolts. The cylinder D lifts the multiple lifting rods 31 to the right and docks the connector with the hose). The lifting rod 31 extends into the connector and fits against the inner wall of the connector. The lifting rod 31 pushes the connector to the right and docks with the hose.

[0036] Two sets of parallel air testing mechanisms 50 are arranged between the capping mechanism 32 and the docking mechanism 22. Air testing is performed through the two sets of air testing mechanisms 50. Each air testing mechanism 50 includes an air testing head 51 and an air testing lifting assembly 59. Multiple air testing heads 51 are installed side by side on the left side of the same air testing plate 60. The air testing lifting assembly 59 is installed on the right side of the air testing plate 60. The air testing lifting assembly 59 is a telescopic cylinder 49W. The telescopic cylinder 49W is installed on the platform by bolts, and an air testing device is installed on the piston rod of the telescopic cylinder 49W by bolts. The test plate 60 is moved to the left by the test lifting assembly 59. Two sets of vertically movable clamping plates 61 are installed on the left platform of the test plate 60. Each set of clamping plates 61 consists of two pieces, one upper and one lower. Each clamping plate 61 is bolted to the platform and fitted with a clamping cylinder. The clamping cylinders clamp the needle and connector (the opposing surfaces of the two clamping plates 61 have mutually fitting serrated grooves). The two sets of clamping plates 61 are located on the left and right sides of the fixture 2, respectively, at the left and right ends of the flexible tube, and clamp the needle and connector respectively. The clamping plate 61 on the clamping side of the connector has a groove on its opposite surface that fits against the outer wall of the connector. The test head 51 rests against the outer wall of the clamping plate 61 and is connected to the connector. The test head 51 is connected to the air pump. A pressure detection module 62 (the pressure detection module 62 is a DLK209 single-ended pressure sensor) is built into the test head 51. The pressure detection module 62 is short-connected to the input of the PLC controller. An alarm is connected to the output of the PLC. When the pressure detection module 62 detects that the pressure is much greater than the pressure set by the PLC, the alarm sounds, and the clamping plate 61 clamps the needle. The device has a groove for clamping the needle. During the air test, the clamping plate 61 is raised and lowered to clamp the connector and the needle. Then, the air test head 51 is connected to the connector, and gas is introduced into the air test head 51. When the intravenous needle is conductive, the air pressure in the air test head 51 is stable. When the intravenous needle is blocked or the flow cross section is small (glue blocks part of the channel), the air pressure measured by the air pressure detection module 62 will increase due to the blockage or small flow. When the air pressure detection module 62 detects that the air pressure is greater than the normal value, it indicates that the intravenous needle is defective. The staff will observe and reject it in time.

[0037] The test head 51 includes a rigid gas tube 52, a rubber gas inlet 53, and a sliding sleeve 54. The rigid gas tube 52 is fitted with the sliding sleeve 54, and the rigid gas tube 52 slides along the sliding sleeve 54. The sliding sleeve 54 is fixed to the test plate 60 by bolts. A frustum-shaped rubber gas inlet 53 is welded to the end of the rigid gas tube 52 facing the connector. The gas inlet 53 has a vent that communicates with the rigid pipe. The rubber gas inlet 53 rests against the clamp plate 61 and communicates with the connector (the end face of the connector is flush with the outer surface of the clamp plate 61). A buffer spring 55 is fitted on the rigid pipe, and both ends of the buffer spring 55 are fixed to the test plate 60 and the rigid pipe by welding, respectively. The rigid gas tube 52 is filled with rigid gas through welding. The baffle 56, which blocks the rigid air pipe 52, has vent holes 57 on both sides of the outer wall of the baffle 56 that communicate with the rigid air pipe 52. An elongated connecting hole 58 is opened on the inner wall of the sliding sleeve 54. When the rigid pipe is misaligned due to the rubber air head 53 pushing against the clamp 61, the two vent holes 57 of the rigid pipe are connected to the connecting hole 58. When the rubber air head 53 moves away from the clamp 61 and returns to its original position, the two vent holes 57 of the rigid pipe are misaligned with the connecting hole 58, thus stopping the air supply. That is, when the rubber air head 53 is against the outer wall of the clamp 61, the rigid air pipe 52 is open. When the rubber air head 53 is separated from the outer wall of the clamp 61, the rigid air pipe 52 is blocked. In this way, there is no need for the air pump to supply air intermittently; the air pump can supply air continuously.

[0038] A capping mechanism 32 is provided on the right side of the end of the hose conveying mechanism 1. The fixture 2 conveys the hose to the capping mechanism 32 for fitting and capping. The capping mechanism 32 includes a cap sorting component 33, a cap linear track 34, a temporary storage seat 35, and a rotating three-jaw chuck 38. The inner wall of the cap is threaded, and the outer wall of the fitting is threaded. The cap sorting component 33 is connected to and interlocks with the cap linear track 34. After sorting by the cap sorting component 33, the caps are conveyed downwards. A movable temporary storage seat 35 is connected at the end of the cap linear track 34. The temporary storage seat 35 can move back and forth (at the end face of the cap linear track 34). A slide rail is fixed to the slide rail by welding. A temporary storage seat 35 is mounted on the slide rail and moves back and forth. A threaded sleeve is fixed to the temporary storage seat 35 by welding. A lead screw driven by a motor is installed on one side of the slide rail via a bearing and bearing housing. The lead screw passes through the threaded sleeve and is threadedly engaged with the threaded sleeve. The rotation of the lead screw drives the translation of the threaded sleeve. Multiple cap insertion slots 36 are opened on the temporary storage seat 35 to mate with multiple cap straight tracks 34. The translation of the temporary storage seat 35 achieves misalignment between the cap straight tracks 34 and the cap insertion slots 36. Caps are transported into the cap insertion slots 36 via the cap straight tracks 34. The lead screw moves the temporary storage seat 35 forward, thus sealing the end of the cap linear track 34. Above the cap insertion groove 36, a rotating three-jaw chuck 38 is positioned vertically opposite to the cap. (The three-jaw chuck has its middle section hinged to the seat body. A chuck cylinder is bolted to the seat body, and a moving disc is mounted on the piston rod of the chuck cylinder. A rod is hinged to one end of the moving disc and the chuck, and the chuck grips the cap by moving the moving disc.) When the cap insertion groove 36 is misaligned with the cap linear track 34, the cap insertion groove 36 and the rotating three-jaw chuck 38 are vertically aligned, and the rotating three-jaw chuck... 38 clamps the cap. Multiple rotating three-jaw chucks 38 are mounted on the same rotating assembly 39. The rotating assembly 39 rotates the rotating three-jaw chucks 38 by 90°, thus transforming the vertical rotating three-jaw chucks 38 into horizontal rotating three-jaw chucks 38. This makes the cap and the connector coaxial. The rotating three-jaw chucks 38 lift the connector and mate with it. The rotating three-jaw chucks 38 rotate simultaneously, thus mate the cap with the connector. The rotating assembly 39 is mounted on the same set of translational assemblies 40. The translational assemblies 40 mate the rotating three-jaw chucks 38 with the connector, thus completing the connection of the connector.

[0039] A detection component 37 is installed in each cap embedding slot 36. The detection component 37 is installed at the bottom of the cap embedding slot 36 with the detection component 37 facing upwards. The detection component 37 is an ST178H infrared reflective proximity switch sensor. When a cap is embedded in the slot 36, the detection component 37 is triggered. The triggering component is connected to the input terminal of the PLC controller. The output terminal of the PLC controller is connected to the stepper motor A that drives the lead screw to rotate. Each time the stepper motor starts, it rotates the temporary storage seat 35 to move the distance of two cap embedding slots 36. When ten caps are placed on the temporary storage seat 35, the three-jaw chuck grasps the caps, and the stepper motor prevents them from being inserted. The line rotates rapidly, and the last cap insertion slot 36 of the temporary storage seat 35 aligns with the cap linear track 34, indicating that a cap is present in the cap insertion slot 36. This causes the temporary storage seat 35 to shift and become misaligned with the cap linear track 34. When the cap in the cap insertion slot 36 is grasped by the rotating three-jaw chuck 38, the detection component 37 de-triggers, and the temporary storage seat 35 moves forward to return to its original position, thus aligning the cap insertion slot 36 with the cap linear track 34. The seats of the multiple rotating three-jaw chucks 38 arranged side-by-side are mounted on the same mounting plate 43 via bearings. With multiple three-jaw chucks arranged side-by-side, the rotating three-jaw chucks 38 rotate relative to the mounting plate 43. The rotating three-jaw chuck 38 is driven by a synchronous pulley 44 bolted onto each rotating three-jaw chuck. Multiple stepper motors B, which drive the synchronous pulleys 44, are bolted onto the mounting plate 43. The synchronous pulleys 44 on the stepper motors B are connected to the synchronous pulleys 44 on the rotating three-jaw chuck 38 via a synchronous belt 45. Thus, the rotation of the rotating three-jaw chuck 38 is achieved by the stepper motors. The rotating assembly 39 is a turntable, with both sides of the mounting plate 43 mounted on the turntable. A translation assembly 40 is mounted on the turntable, comprising a mounting frame 41 and guide posts 42. The bottom of the mounting frame 41 is bolted to the table surface. The turntable and the mounting frame 41 rotate in conjunction (turntable...). The system includes a rotating plate and shafts. Shafts are fixed to both ends of the rotating plate by welding. The two shafts are mounted on the mounting plate via bearings. Cams are welded to the two shafts of the turntable. Cylinder A is hinged between the cams and the mounting bracket 41. The turntable rotates 90° reciprocatingly by extending and retracting cylinder A. Guide posts 42 are welded to the rotating plate of the turntable. Guide posts 42 pass through the mounting plate 43. The mounting plate 43 moves on the guide posts 42. Cylinder B is bolted between the mounting plate 43 and the turntable. The mounting plate 43 translates by extending and retracting cylinder B.

[0040] The aforementioned cylinders, telescopic cylinder 49, finger cylinder, motor, and stepper motor are all controlled by a PLC controller. The PLC controller controls the operation of these actuators to achieve automated processing. The cylinders, telescopic cylinder 49, and finger cylinder are all controlled by a solenoid valve connected to the PLC controller. The motor and stepper motor are also controlled by a controller box connected to the PLC controller. The use of a PLC controller to control multiple cylinders, telescopic cylinder 49, finger cylinder, motor, and stepper motor is existing technology.
