[0046] like Figures 1 to 15 As shown, it is a preferred embodiment provided by the present invention.

[0047] The automatic assembly equipment 1000 of high-pressure contrast injection syringe provided in this embodiment comprises a frame 700 and a transfer device 300, a piston loading device 200, a sealing sleeve loading device 400, a jacket loading device 500 and an infusion set unloading device 600 supported on the frame 700.

A plurality of piston fixing seats 311 are distributed at intervals and used to fix the piston component 110; the piston loading device 200 is used to provide the piston component 110 and place the piston component 110 on the piston fixing seat 311; the sealing sleeve loading device 400 is used to provide the sealing sleeve component 120 and press the piston component 110 onto the piston component 110 located on the piston fixing seat 311; the outer sleeve loading device 500 is used to provide the outer sleeve component 130 and put the outer sleeve component 130 on the piston component 110 and the sealing sleeve component 120 that are located on the piston fixing seat 311 and connected to each other to assemble an infusion set syringe 100; the infusion set unloading device 600 is used to move the infusion set syringe 100 away from the transfer device 300.

[0048] The above-mentioned high-pressure contrast syringe automatic assembly equipment 1000 adopts a transfer device 300, a piston loading device 200, a sealing sleeve loading device 400, a jacket loading device 500 and an infusion set unloading device 600. The piston loading device 200, the sealing sleeve loading device 400, the jacket loading device 500 and the infusion set unloading device 600 are arranged around the transfer device 300. In this way, the automatic assembly of the infusion set syringe 100 can be realized with a high degree of automation, thereby improving production efficiency and saving production costs.

[0049] See also Figure 3 and 4The transfer device 300 includes a chassis 350, a turntable 310 and a turntable drive assembly 320. The turntable 310 is rotatably supported on the chassis 350. The turntable drive assembly 320 drives the turntable 310 to intermittently indexed rotate relative to the chassis 350. The chassis 350 has a plurality of workstations. The turntable 310 is provided with a plurality of piston fixing seats 311 for fixing the piston member 110. The number of the piston fixing seats 311 is the same as the number of the workstations. The plurality of piston fixing seats 311 are evenly spaced along the circumference of the turntable 310.

[0050] See also Figure 3 and 4 In the present embodiment, the number of the piston fixing seats 311 is but not limited to six, and the number of the workstations of the chassis 350 is but not limited to six, which are respectively divided into a first workstation 35a for loading a piston component 110, a piston detection workstation 35e, a second workstation 35b for loading a sealing sleeve component 120 and connecting the sealing sleeve component 120 with the piston component 110, a sealing sleeve detection workstation 35f, a third workstation 35c for loading a coat component 130 and sleeve-mounting the coat component 130 outside the interconnected piston component 110 and the sealing sleeve component 120 to assemble an infusion set syringe 100, and a fourth workstation 35d for unloading the infusion set syringe 100. A first detection device 330 is provided on the piston detection station 35e of the chassis 350 to detect whether a piston member 110 is placed on the piston fixing seat 311 located in the station, and the first detection device 330 includes a detection bracket and a photoelectric detection sensor installed on the detection bracket. A second detection device 340 is provided on the sealing sleeve detection station 35f of the chassis 350 to detect the relative position detection between the sealing sleeve member 120 and the sealing sleeve member 120 on the piston fixing seat 311 located in the station, and the second detection device 340 includes a detection bracket and a photoelectric detection sensor installed on the detection bracket. The turntable drive assembly 320 includes a turntable drive member 321 and a divider 322 connected to the turntable drive member 321, and the output shaft of the divider 322 is connected to the turntable 310, wherein the turntable drive member 321 is but not limited to a reduction motor, and the divider 322 is a six-position divider 322. When the rotating disk 310 stops, the six piston fixing seats 311 correspond to the six piston fixing seats 311 one by one.

[0051] In another embodiment, the number of workstations is four, the number of piston fixing seats 311 is four, and the divider 322 is a four-position divider 322. The four workstations are sequentially divided along the circumference of the turntable 310 into a first workstation 35a for loading a piston member 110, a second workstation 35b for loading a sealing sleeve member 120 and connecting the sealing sleeve member 120 with the piston member 110, a third workstation 35c for loading a jacket member 130 and sleeve the jacket member 130 outside the piston member 110 and the sealing sleeve member 120 connected to each other to assemble the infusion set syringe 100, and a fourth workstation 35d for unloading the infusion set syringe 100. When the turntable 310 stops, the four piston fixing seats 311 correspond to the four one-to-one.

[0052] See also Figures 5 to 7 The piston loading device 200 of this embodiment is used to provide a piston component 110 and place the piston component 110 on a piston fixing seat 311. The piston loading device 200 includes a piston vibration plate 210, a piston receiving seat 220 and a piston moving device 230.

[0053] from Figure 5 It can be seen that the piston vibration plate 210 is used to deliver multiple piston components 110 through a piston feed channel 211, the piston receiving seat 220 is used to receive the piston components 110 delivered from the piston feed channel 211, and the piston moving device 230 is used to clamp the piston component 110 on the piston receiving seat 220 and move the piston component 110 to the piston fixing seat 311 and maintain it with the piston fixing seat 311. In this embodiment, the outlet of the piston vibration disk 210 is connected to the inlet of the piston feed channel 211. The piston vibration disk 210 sends multiple piston components 110 through a piston feed channel 211 through vibration. The piston receiving seat 220 is located at the outlet of the piston feed channel 211 and can receive the piston components 110 sent from the piston feed channel 211. After the piston component 110 moves to the piston receiving seat 220, its position is maintained by the piston receiving seat 220, and the other piston components 110 of the piston feed channel 211 are also blocked by the piston components 110 to be grasped on the piston receiving seat 220 to stop moving. The piston moving device 230 grabs the piston component 110 from above the piston receiving seat 220, and moves to the loading station after lifting the piston component 110. That is to say, by pouring multiple piston components 110 into the piston vibration plate 210, the piston components 110 are sent into the piston feed channel 211 through the vibration of the piston vibration plate 210. The piston components 110 are transported side by side and in an orderly manner in the piston feed channel 211. The piston feed channel 211 sends the piston components 110 one by one to the piston receiving seat 220, and then the piston moving device 230 grabs the material for loading, thereby realizing the automatic loading of the piston components 110 and improving the production efficiency.

[0054] In other embodiments, a blowing assembly is disposed in the piston feed channel 211 to push the piston member 110 to move by air flow.

[0055] In other embodiments, a roller assembly is disposed in the piston feed channel 211 to move the piston member 110 by rolling.

[0056] See also Figures 5 to 7 The piston moving device 230 includes a piston moving mounting bracket 231, a piston clamping manipulator 232 for clamping and fixing the piston component 110, a piston translation driving component 233 for making the piston clamping manipulator 232 translate relative to the piston moving mounting bracket 231, and a piston lifting driving component 234 for making the piston clamping manipulator 232 lift and lower relative to the piston moving mounting bracket 231. In this embodiment, the piston clamping manipulator 232 includes a piston clamping mounting seat 2321, a piston clamping arm 2322 and a piston clamping driving member 2323. The number of the piston clamping arms 2322 is but not limited to two. The two piston clamping arms 2322 are installed on the piston clamping mounting seat 2321 in a left-right symmetrical manner (left-right direction in the figure). The upper ends of the two piston clamping arms 2322 are respectively pivotally attached to the piston clamping mounting seat 2321 with a direction parallel to the translational movement direction of the piston clamping manipulator 232 as an axis, and can move relative to each other. The piston clamping driving member 2323 is but not limited to a cylinder, which is respectively connected to the two piston clamping arms 2322 and can drive the two piston clamping arms 2322 to move so as to clamp and release the piston component 110. It is easy to understand that the two piston clamping arms 2322 can swing up and down around the pivot axis between them and the piston clamping mounting base 2321. When swinging upward, the piston clamping manipulator 232 is in an extended state; when swinging downward, the bottom ends of the two piston clamping arms 2322 move toward each other, the piston clamping manipulator 232 is in a retracted state, and abuts against the side wall of the piston component 110 to clamp and fix the piston component 110.

[0057] Specifically, a piston moving slide rail 235 is fixedly provided on the piston moving mounting bracket 231, and a piston moving slider 236 connected to the piston translation driving member 233 is slidably provided on the piston moving slide rail 235, and the piston translation driving member 233 is but not limited to a cylinder, and the piston lifting driving member 234 is supported on the piston moving slider 236 and connected to the piston clamping manipulator 232, and the piston lifting driving member 234 is but not limited to a cylinder. It is easy to understand that the piston moving slider 236 is driven to move forward and backward (in the front and rear direction of the figure) by the extension and contraction of the piston translation driving member 233, and the piston clamping manipulator 232 is driven to move up and down (in the up and down direction of the figure) by the extension and contraction of the piston lifting driving member 234. In this way, after the piston component 110 is clamped on the piston receiving seat 220, the piston lifting driving member 234 controls the piston clamping manipulator 232 and the clamped piston component 110 to move up, and then the piston translation driving member 233 moves the piston component 110 to the loading station.

[0058] As a further optimization, the piston moving mounting bracket 231 is provided with a piston buffer limiting member 237 for abutting against the piston moving sliding block 236 , and the buffer limiting member may be a spring shock absorber.

[0059] Please continue to see Figures 5 to 7 Each piston clamping arm 2322 has a piston clamping end 2324 for abutting against the side wall of the piston member 110, and a side surface of each piston clamping end 2324 facing the other piston clamping end 2324 has an arc-shaped clamping surface 2325, and the curvature of the arc-shaped clamping surface 2325 matches the curvature of the side wall of the piston member 110. It should be noted that when the two piston clamping arms 2322 are in the clamping position, the arc-shaped clamping surface 2325 of the piston clamping end 2324 is substantially in contact with the side wall surface of the piston member 110, so that effective contact between the piston clamping arm 2322 and the piston member 110 can be ensured, which is conducive to clamping the piston member 110.

[0060] As a further optimization, an angle limiting member 238 is provided on the piston clamping mounting seat 2321 to limit the swinging amplitude of the piston clamping arm 2322, so as to prevent the piston clamping arm 2322 from swinging outward (i.e., upward) too much and causing damage.

[0061] As a further optimization, the piston receiving seat 220 has a piston receiving positioning groove 221 located on the top surface thereof, for allowing the piston component 110 in the piston feed channel 211 to slide in and position and fix the piston component 110.

[0062] See also Figure 7The piston loading device 200 of this embodiment also includes a protective cover 212, which is arranged on the piston vibration plate 210 and has a discharge cover port 213 corresponding to the piston feed channel 211. In this way, by setting the protective cover 212, the noise generated by the piston vibration plate 210 can be reduced.

[0063] As a further optimization, a material taking and discharging port is provided on the protective cover 212, and a material taking and discharging door cover 214 for opening and closing the material taking and discharging port is provided on the protective cover 212. It is easy to understand that by opening the material taking and discharging door cover 214, the piston component 110 can be poured into the piston vibration plate 210 through the material taking and discharging port.

[0064] See also Figure 8 and 9 The sealing sleeve feeding device 400 of this embodiment is used to provide the sealing sleeve component 120 and press the piston component 110 onto the piston component 110 located on the piston fixing seat 311. The sealing sleeve feeding device 400 includes a sealing sleeve vibration plate 410, a sealing sleeve receiving seat 420 and a sealing sleeve moving device 430.

[0065] from Figure 8It can be seen that the sealing sleeve vibration plate 410 is used to deliver multiple sealing sleeve components 120 through a sealing sleeve feed channel 411, the sealing sleeve receiving seat 420 is used to receive the sealing sleeve components 120 delivered from the sealing sleeve feed channel 411, and the sealing sleeve moving device 430 is used to adsorb the sealing sleeve components 120 on the sealing sleeve receiving seat 420, and move the sealing sleeve components 120 to above the piston fixing seat 311, and press the sealing sleeve components 120 with the piston component 110 located on the piston fixing seat 311. In this embodiment, the outlet of the sealing sleeve vibration disk 410 is connected to the inlet of the sealing sleeve feed channel 411, and the sealing sleeve vibration disk 410 sends multiple sealing sleeve components 120 through a sealing sleeve feed channel 411 by vibration. The sealing sleeve receiving seat 420 is located at the outlet of the sealing sleeve feed channel 411 and can receive the sealing sleeve components 120 sent out from the sealing sleeve feed channel 411. After the sealing sleeve component 120 moves to the sealing sleeve receiving seat 420, its position is maintained by the sealing sleeve receiving seat 420, and other sealing sleeve components 120 of the sealing sleeve feed channel 411 are also blocked by the sealing sleeve components 120 to be grasped on the sealing sleeve receiving seat 420 to stop moving. The sealing sleeve moving device 430 grabs the sealing sleeve component 120 from above the sealing sleeve receiving seat 420, and moves to the loading station after lifting the sealing sleeve component 120. That is to say, by pouring a plurality of sealing sleeve components 120 into the sealing sleeve vibration plate 410, the sealing sleeve components 120 are sent into the sealing sleeve feeding channel 411 through the vibration of the sealing sleeve vibration plate 410, and the sealing sleeve components 120 are transported side by side and orderly in the sealing sleeve feeding channel 411. The sealing sleeve feeding channel 411 sends the sealing sleeve components 120 one by one to the sealing sleeve receiving seat 420, and then the sealing sleeve moving device 430 grabs the material, thereby realizing the automatic loading of the sealing sleeve components 120 and improving the production efficiency.

[0066] In other embodiments, a blowing assembly is disposed in the sealing sleeve feed channel 411 to push the sealing sleeve component 120 to move by airflow.

[0067] In other embodiments, a roller assembly is disposed in the sealing sleeve feed channel 411 to move the sealing sleeve component 120 by rolling.

[0068] See also Figure 8 and 9The sealing sleeve moving device 430 includes a sealing sleeve moving mounting bracket 431, a sealing sleeve adsorption assembly 432 for adsorbing and fixing the sealing sleeve member 120, a sealing sleeve translation driving member 433 for making the sealing sleeve adsorption assembly 432 translate relative to the sealing sleeve moving mounting bracket 431, and a sealing sleeve lifting driving member 434 for making the sealing sleeve adsorption assembly 432 move up and down relative to the sealing sleeve moving mounting bracket 431. The sealing sleeve adsorption assembly 432 is connected to an air extraction device (not shown). In this embodiment, the sealing sleeve adsorption assembly 432 includes an inverted cone-shaped suction nozzle part 4321 and a sealing sleeve connecting column 4322 connected between the suction nozzle part 4321 and the sealing sleeve lifting driving member 434. The suction nozzle part 4321 has an adsorption cavity (not shown) for the sealing sleeve component 120 to be placed and open downward. The shape of the adsorption cavity matches the shape of the sealing sleeve component 120, that is, the cross-sectional shape of the adsorption cavity is a triangle with a sharp top and a wide bottom (in the up and down direction of the figure). The side wall of the suction nozzle part 4321 is provided with an inlet and outlet air hole 4323 for connecting with the suction device and communicating with the adsorption cavity. In this way, after the suction nozzle part 4321 moves above the sealing sleeve receiving seat 420, it is pressed down and covered on the outside of the sealing sleeve component 120 to be grasped, and the suction device vacuums the inside of the suction nozzle part 4321, thereby sucking the sealing sleeve component 120 tightly in the adsorption cavity of the suction nozzle part 4321. It should be noted that, after the sealing sleeve component 120 is sent into the sealing sleeve feed channel 411 through the sealing sleeve vibration disk 410, the sealing sleeve component 120 is set with the tip facing upward and the concave cavity opening facing downward. After the suction nozzle component 4321 adsorbs and fixes the sealing sleeve component 120, as the suction nozzle component 4321 moves, the sealing sleeve component 120 is in a state with the concave cavity opening facing downward. That is to say, during assembly, the sealing sleeve lifting drive 434 can be used to drive the suction nozzle component 4321 to move downward, so that the sealing sleeve component 120 can be nested on the piston component 110.

[0069] Specifically, a sealing sleeve moving slide rail 435 is fixedly provided on the sealing sleeve moving mounting bracket 431, and a sealing sleeve moving slider 436 connected to the sealing sleeve translation driving member 433 is slidably provided on the sealing sleeve moving slide rail 435. The sealing sleeve translation driving member 433 is but not limited to a cylinder. The sealing sleeve lifting driving member 434 is supported on the sealing sleeve moving slider 436 and connected to the sealing sleeve adsorption assembly 432. The sealing sleeve lifting driving member 434 is but not limited to a cylinder. It is easy to understand that the sealing sleeve moving slider 436 is driven to move left and right (left and right direction as shown in the figure) by the extension and retraction of the sealing sleeve translation driving member 433, and the sealing sleeve adsorption assembly 432 is driven to move up and down (up and down direction as shown in the figure) by the extension and retraction of the sealing sleeve lifting driving member 434. In this way, after the sealing sleeve component 120 is adsorbed on the sealing sleeve receiving seat 420, the sealing sleeve lifting driving member 434 controls the sealing sleeve adsorption assembly 432 and the adsorbed sealing sleeve component 120 to move upward, and then the sealing sleeve component 120 is moved to the loading station through the sealing sleeve translation driving member 433.

[0070] As a further optimization, the sealing sleeve movable mounting bracket is provided with a sealing sleeve buffer limiting member 437 for abutting against the sealing sleeve movable slider 436, and the buffer limiting member may be a spring shock absorber.

[0071] Please continue to see Figure 8 and 9 A nozzle guide block 438 is provided on the sealing sleeve moving slider 436, and the sealing sleeve connecting column 4322 is penetrated by the nozzle guide block 438. The nozzle guide block 438 and the sealing sleeve connecting column 4322 are guided by each other to improve the movement stability of the nozzle component 4321. It is worth mentioning that, since a certain downward force is required when the sealing sleeve component 120 is nested on the piston component 110 (not shown in the figure), the nozzle guide block 438 can better ensure that the position of the nozzle component 4321 will not shift during the downward pressing process, thereby improving the yield rate.

[0072] As a further optimization, a waist-shaped assembly hole 4324 is provided on the suction nozzle component 4321, so that the connection and fixation between the suction nozzle component 4321 and the sealing sleeve connecting column 4322 can be facilitated.

[0073] As a further optimization, the sealing sleeve material receiving seat 420 has a sealing sleeve material receiving positioning groove 421 located on the top surface thereof, for allowing the sealing sleeve component 120 in the sealing sleeve material feeding channel 411 to slide in and position and fix the sealing sleeve component 120.

[0074] See also Fig. 9The sealing sleeve feeding device 400 of this embodiment also includes a protective cover 412, which is arranged on the sealing sleeve vibration disk 410 and has a discharge cover port 413 corresponding to the sealing sleeve feeding channel 411. In this way, by setting the protective cover 412, the noise generated by the sealing sleeve vibration disk 410 can be reduced.

[0075] As a further optimization, a material taking and discharging port is provided on the protective cover 412, and a material taking and discharging door cover 414 for opening and closing the material taking and discharging port is provided on the protective cover 412. It is easy to understand that by opening the material taking and discharging door cover 414, the sealing sleeve component 120 can be poured into the sealing sleeve vibration disk 410 through the material taking and discharging port.

[0076] See also Figures 10 to 13 The outer jacket loading device 500 of this embodiment is used to provide an outer jacket component 130, and the outer jacket component 130 is sleeved outside the piston component 110 and the sealing sleeve component 120 that are located on the piston fixing seat 311 and connected to each other, so as to assemble the infusion set syringe 100. The outer jacket loading device 500 includes an outer jacket conveying device 510, an outer jacket receiving seat 520 and an outer jacket moving device 530.

[0077] from Fig.10 It can be seen that the outer jacket conveying device 510 has an outer jacket feed channel 511 for placing the outer jacket member 130 and transporting the outer jacket member 130 in the outer jacket feed channel 511. In this embodiment, the outer jacket conveying device 510 includes an outer jacket conveying belt 512 and an outer jacket conveying drive assembly (not shown in the figure). The outer surface of the outer jacket conveying belt 512 forms the outer jacket feed channel 511. The outer jacket feed channel 511 has an inlet located at its left end (the left end in the figure) and an outlet located at the right end (the right end in the figure). Multiple outer jacket members 130 can be manually placed one by one from the inlet. Multiple outer jacket members 130 are placed side by side on the outer jacket conveying belt 512 and carried by the outer jacket conveying belt 512. The outer jacket conveying drive assembly is but not limited to a motor drive assembly. The outer jacket conveying belt 512 can be rotated by the drive of the outer jacket conveying drive assembly. It is easy to understand that the outer jacket conveying drive assembly drives the outer jacket conveying belt 512 to rotate, thereby moving the outer jacket member 130 from the inlet to the outlet.

[0078] See also Fig.10 In this embodiment, the coat conveying device 510 also includes a coat guardrail assembly 513 arranged on the coat conveyor belt 512. The coat guardrail assembly 513 and the coat conveyor belt 512 jointly define the above-mentioned coat feed channel 511. It can be understood that the coat guardrail assembly 513 can protect the coat component 130 during the movement process of the coat component 130 to prevent the coat component 130 from falling.

[0079] See also Figures 10 to 13The outer jacket receiving seat 520 is located at the outlet of the outer jacket feeding channel 511 and is used to receive the outer jacket component 130 sent out from the outer jacket feeding channel 511. In this embodiment, the outer jacket receiving seat 520 has an outer jacket receiving positioning groove 521 for the outer jacket component 130 in the outer jacket feeding channel to slide into. After the outer jacket component 130 moves to the outer jacket receiving positioning groove 521 of the outer jacket receiving seat 520, its position is maintained by the outer jacket receiving seat 520, and other outer jacket components 130 in the outer jacket feeding channel 511 are also blocked by the outer jacket component 130 to be grasped on the outer jacket receiving seat 520 to stop moving.

[0080] from Figures 11 to 13 It can be seen that, specifically, the outer jacket receiving material positioning groove 521 has two groove walls parallel to each other, and the outer jacket receiving material seat 520 is provided with an outer jacket arranging and positioning mechanism, which is used to extend from the groove wall into the outer jacket receiving material positioning groove 521 and position and center the outer jacket component 130. In other words, after the outer jacket component 130 slides into the outer jacket receiving material positioning groove 521 from the outer jacket feeding channel 511, the outer jacket arranging and positioning mechanism is used to position the outer jacket component 130 before it is grasped, thereby ensuring the grasping position and accuracy, and facilitating grasping.

[0081] In the present embodiment, the jacket arrangement and positioning mechanism includes a pair of jacket positioning components 522, each jacket positioning component 522 includes a jacket positioning member 523 slidably arranged on the jacket receiving seat 520 and a jacket positioning driving member 524 for driving the jacket positioning member 523 to move, and the side wall of the jacket positioning member 523 is provided with an insertion groove 525 for the outer edge of the jacket member 130 to be inserted, and the jacket positioning driving member 524 is but not limited to a cylinder. It is worth mentioning that the two groove walls of the jacket receiving positioning groove 521 are formed with an insertion groove 526 for the outer edge of the jacket member 130 to be inserted, and the insertion groove 526 and the insertion groove 525 are basically located at the same horizontal height. After the jacket member 130 slides into the jacket receiving positioning groove 521, the jacket member 130 The outer edge of the coat member 130 is inserted into the insertion groove 526 and limited in the height direction. The coat positioning member 523 is pushed to move relatively through the coat positioning driving members 524 on both sides. The outer edge of the coat member 130 is inserted into the insertion groove 525, and the coat positioning member 523 directly abuts against the outer wall of the coat member 130, thereby positioning and limiting the coat member 130 in the left and right directions.

[0082] See also Figures 10 to 13The outer jacket moving device 530 is used to grab the outer jacket component 130 on the outer jacket receiving seat 520, and move the outer jacket component 130 to the top of the piston fixing seat 311, and assemble the outer jacket component 130 with the piston component 110 and the sealing sleeve component 120 located on the piston fixing seat 311 to form the infusion set syringe 100. The outer jacket moving device 530 includes an outer jacket mounting frame 531, an outer jacket clamping mechanism 532 for clamping and fixing the outer jacket component 130, an outer jacket translation driving member 533 for making the outer jacket clamping mechanism 532 translate relative to the outer jacket mounting frame 531, and an outer jacket lifting driving member 534 for making the outer jacket clamping mechanism 532 move up and down relative to the outer jacket mounting frame 531. In this embodiment, the coat clamping mechanism 532 includes a clamping bracket 5321 and a pair of coat clamping assemblies 5322 arranged on the clamping bracket 5321 and capable of relatively opening and closing movements to clamp and release the coat member 130. The clamping bracket 5321 has two clamping support plates 5323 parallel to each other, and a coat clamping space 5324 is constructed between the two clamping support plates 5323. The two coat clamping assemblies 5322 correspond to the two clamping support plates 5323 one by one, and each coat clamping assembly 5322 includes a coat clamping claw member 5325 and a clamping claw driving member 5326 for moving the coat clamping claw member 5325 in a direction perpendicular to the surface of the clamping support plate 5323. The clamping claw driving member 5326 is, but not limited to, a cylinder, and the clamping claw driving members 5326 on both sides respectively drive the coat clamping claw members 5325 to move relatively, thereby clamping and releasing the coat member 130. It should be noted that after the outer jacket moving device 530 clamps the outer jacket component 130 on the outer jacket receiving seat 520 , the outer jacket positioning components 523 will move outwards and separate from the outer jacket component 130 , thereby avoiding mutual interference with the outer jacket moving device 530 .

[0083] Specifically, a coat moving slide rail 535 is fixedly provided on the coat mounting frame 531, and a coat moving bracket 536 connected to the coat translation driving member 533 is slidably provided on the coat moving slide rail 535, and the coat translation driving member 533 is but not limited to a cylinder, and the coat lifting driving member 534 is supported on the coat moving bracket 536 and connected to the coat clamping mechanism 532, and the coat lifting driving member 534 is but not limited to a cylinder. It is easy to understand that the coat moving bracket 536 is driven to move on the coat moving slide rail 535 by the extension and contraction of the coat translation driving member 533, and the coat clamping mechanism 532 is driven to move up and down (up and down direction in the figure) by the extension and contraction of the coat lifting driving member 534, so that after the coat component 130 is clamped on the coat receiving seat 520, the coat lifting driving member 534 controls the coat clamping mechanism 532 and the clamped coat component 130 to move up, and then the coat translation driving member 533 moves the coat component 130 to the loading station.

[0084] As a further optimization, the coat mounting frame 531 is provided with a coat buffering limiter 537 for abutting against the coat moving bracket 536 , and the buffering limiter may be a spring shock absorber.

[0085] Please continue to see Figures 10 to 13 In this embodiment, each outer jacket clamping claw member 5325 has an outer jacket clamping end 5327 for abutting against the side wall of the outer jacket member 130, and a side surface of each outer jacket clamping end 5327 facing the other outer jacket clamping end 5327 has an arc-shaped clamping surface, and the curvature of the arc-shaped clamping surface is adapted to the curvature of the side wall of the outer jacket member 130. It should be noted that when the two outer jacket clamping claw members 5325 are in the clamping position, the arc-shaped clamping surface of the outer jacket clamping end 5327 is substantially in contact with the side wall surface of the outer jacket member 130, so that effective contact between the outer jacket clamping end 5327 and the outer jacket member 130 can be ensured, which is conducive to ensuring the stability of the outer jacket member 130.

[0086] See also Figures 10 to 13 In this embodiment, each jacket clamping assembly 5322 further includes a jacket pressing member 5328 for abutting against the outer edge of the jacket member 130 to press the jacket member 130 downward, and the jacket pressing member 5328 is fixedly connected to the jacket clamping claw member 5325. It is worth mentioning that the jacket member 130 is transported on the jacket conveying device 510, positioned on the jacket receiving seat 520, and moved by the jacket moving device 530, and is arranged with the opening direction facing downward (below the figure). In this way, when assembling, the jacket clamping mechanism 532 is moved downward by the jacket lifting drive member 534, and the lower end (lower end in the figure) of the jacket pressing member 5328 abuts against the outer edge upper surface (upper surface in the figure) of the jacket member 130, so as to provide a sufficient downward pressure on the jacket member 130, and press the piston member 110 and the sealing sleeve member 120 located below the jacket member 130 and connected to each other into the jacket member 130.

[0087] See also Fig.14 and 15 The infusion set unloading device 600 of this embodiment is used to move the infusion set syringe 100 away from the transfer device 300. The infusion set unloading device 600 includes a unloading conveying device 610 and a syringe conveying device 620. The transfer device 300 includes a turntable 310 and a turntable driving assembly 320 for rotating the turntable 310. The turntable driving assembly 320 is but not limited to a motor assembly, so as to realize the movement of the infusion set syringe 100 between various stations of the turntable 310.

[0088] from Fig.14 and 15It can be seen that the feeding and conveying device 610 has a feeding channel 611 for placing the infusion set syringe 100 and transporting the infusion set syringe 100 in the feeding channel 611 . In this embodiment, the unloading conveying device 610 includes a syringe conveyor belt 612 and a syringe conveying drive assembly (not shown in the figure). The outer surface of the syringe conveyor belt 612 forms the above-mentioned unloading channel 611. The unloading channel 611 has an inlet located at its right end (the right end shown in the figure) and an outlet located at the left end (the left end shown in the figure). The syringe conveying drive assembly is but not limited to a motor drive assembly. The syringe conveyor belt 612 can be rotated by the drive of the syringe conveying drive assembly. It should be noted that the syringe transporting device 620 places the assembled infusion set syringes 100 from the middle loading device 300 one by one from the inlet into the unloading channel 611, and is carried by the syringe conveyor belt 612 and moved to the outlet. The infusion set syringes 100 can be collected, transported and stored at the outlet manually.

[0089] See also Fig.14 and 15 In this embodiment, the discharge conveying device 610 also includes a syringe guardrail assembly 613 arranged on the syringe conveyor belt 612. The syringe guardrail assembly 613 and the syringe conveyor belt 612 jointly define the above-mentioned discharge channel 611. It can be understood that the syringe guardrail assembly 613 can protect the infusion set syringe 100 during the movement process of the infusion set syringe 100 to prevent the infusion set syringe 100 from falling.

[0090] See also Fig.14 and 15 The syringe conveying device 620 reciprocates between the middle loading device 300 and the unloading conveying device 610 to move the infusion set syringe 100 on the middle loading device 300 to the unloading channel 611. The syringe conveying device 620 includes a syringe mounting frame 621, a syringe clamping assembly 622 for clamping and fixing the infusion set syringe 100, a syringe translation driving member 623 for making the syringe clamping assembly 622 translate relative to the syringe mounting frame 621, and a syringe lifting driving member 624 for making the syringe clamping assembly 622 move relative to the syringe mounting frame 621. In this embodiment, the syringe clamping assembly 622 includes a syringe clamping mounting seat 6221, two syringe clamping arms 6222 pivotally attached to the syringe clamping mounting seat 6221 with a direction parallel to the lifting and lowering movement direction of the syringe clamping assembly 622 (the up and down direction in the figure, i.e., the direction perpendicular to the surface of the turntable 310) as an axis and capable of relative opening and closing movements, and a syringe clamping drive 6223 for driving the two syringe clamping arms 6222 to move and clamp and release the infusion set syringe 100. The syringe clamping drive 6223 is, but is not limited to, a cylinder.

[0091] Fig.14In the syringe transport device 620 shown, the syringe clamping arm 6222 is in the clamping position and clamps the infusion set syringe 100; Fig.15 In the syringe transport device 620 shown in FIG. 1 , the syringe clamp arm 6222 is in a released position and releases the infusion set syringe 100.

[0092] Please continue to see Fig.14 and 15 Each syringe clamping arm 6222 has a syringe clamping end 6224 for abutting against the side wall of the infusion set syringe 100, and a side surface of each syringe clamping end 6224 facing another syringe clamping end 6224 has an arc-shaped clamping surface, and the curvature of the arc-shaped clamping surface is adapted to the curvature of the side wall of the infusion set syringe 100. It should be noted that the syringe clamping end 6224 is curved outward from the syringe clamping mounting seat 6221, and the swing angle range of the syringe clamping end 6224 is but not limited to 0 to 90 degrees. It can be understood that when the two syringe clamping arms 6222 are in the clamping position, the arc-shaped clamping surface of the syringe clamping end 6224 is basically in contact with the side wall surface of the infusion set syringe 100. In this way, effective contact between the syringe clamping end 6224 and the infusion set syringe 100 can be ensured, which is beneficial to ensuring the stability of the infusion set syringe 100.

[0093] As a further optimization, an elastic gasket 6225 is provided inside the syringe clamping arm 6222 to abut against the side wall of the infusion set syringe 100. The elastic gasket 6225 can be made of rubber, foam, etc. Thus, by providing the elastic gasket 6225, deformation and damage of the infusion set syringe 100 can be avoided, and the friction with the infusion set syringe 100 can be increased.

[0094] Specifically, a syringe moving slide rail 625 is fixedly arranged on the syringe mounting frame 621, and a syringe moving seat 626 connected to a syringe translation drive member 623 is slidably arranged on the syringe moving slide rail 625. The syringe translation drive member 623 is but not limited to a cylinder. The syringe lifting drive member 624 is supported on the syringe moving seat 626 and connected to the syringe clamping assembly 622. The syringe lifting drive member 624 is but not limited to a cylinder. It is easy to understand that the syringe moving seat 626 is driven to move on the syringe moving slide rail 625 through the extension and retraction of the syringe translation drive 623, and the syringe clamping assembly 622 is driven to move up and down (up and down directions shown in the figure) through the extension and retraction of the syringe lifting drive 624. In this way, after the middle loading device 300 clamps the infusion set syringe 100, the syringe lifting drive 624 controls the syringe clamping assembly 622 and the clamped infusion set syringe 100 to move upward, and then the infusion set syringe 100 is moved to the unloading conveying device 610 through the syringe translation drive 623.

[0095] See also Fig.14 and15 A clamping guide assembly is provided between the syringe clamping assembly 622 and the syringe moving seat 626. The clamping guide assembly includes a clamping guide rail 627 and a clamping slider 628 that are slidably connected to each other. One end of the clamping guide rail 627 is fixed to the syringe clamping assembly 622 and extends in a direction parallel to the lifting and lowering movement direction of the syringe clamping assembly 622. The clamping slider 628 is fixed to the syringe moving seat 626. It is easy to understand that by providing the clamping guide assembly, the stability of the lifting and lowering movement of the syringe clamping assembly 622 can be ensured, and the infusion device syringe 100 can be prevented from shaking left and right when lifting and lowering.

[0096] As a further optimization, the syringe mounting frame 621 is provided with a syringe buffer limiter 629 for abutting against the syringe moving seat 626, and the buffer limiter can be a spring shock absorber.
