Description

Technical Field

[0001] This technical solution relates to the field of medical device manufacturing equipment technology, specifically to an assembly system for a needle-piercing device. Background Technology

[0002] A vial-piercing needle is a medical device used to pierce the rubber or plastic stoppers of containers such as medicine bottles to inject or extract liquids. It typically consists of a stainless steel needle tube and a plastic / metal needle hub. In use, the operator aligns the needle tube with the stopper and pierces it, allowing the liquid to be transferred through the needle.

[0003] The production of needle-piercing syringes often employs mechanized assembly lines, such as the automated assembly line for syringes disclosed in Chinese patent CN201911211777.1. This line assembles the needle by attaching the needle hub, inserting the needle tube into the hub and securing it with glue, and then covering the needle tube with a sheath. To balance the internal and external air pressures during liquid injection or extraction, existing needle-piercing syringes also feature a rear seat with a venting channel. One venting hole of the venting channel enters the container along with the needle tube, while the other venting hole is located outside the container. This external venting hole is fitted with a filter paper structure that allows gas to pass through but prevents liquid from passing through.

[0004] The improved needle requires an additional seat and filter structure, which means that the original assembly equipment, which was only designed for needle tubes, needle seats and sheaths, cannot be adapted to the assembly requirements of the new components and cannot meet the production requirements of the improved needle. Summary of the Invention

The system uses an upper rear seat device to install the rear seat onto the needle holder, and an upper filter paper device and an upper retaining ring device to install the filter paper and retaining ring onto the rear seat, thereby assembling the bottle-piercing needle. This improves the problem that existing assembly equipment cannot adapt to the assembly of new components such as the rear seat and filter paper, thus failing to meet the production needs of improved bottle-piercing needles, and also improves the problem of the lack of waste paper recycling in existing filter paper flushing devices.

[0036] The needle seat device 11, needle press device 12, needle tube device 13, glue application device 14, drying device 16, plug detection device 17, imaging device 18, silicone oil application device 19, defective product rejection device 110, sheath application device 113, sheath pressing device 114, unloading device 119, and conveying mechanism are all existing technologies. For specific structures, please refer to the design scheme disclosed in Chinese Patent CN201911211777.1. The structure of the back seat pressing device 112 is the same as that of the needle press device 12 or the sheath pressing device 114. The defective product ejection device 118 and the defective product rejection device 110 have the same structure.

[0037] like Figure 2 The piercing needle 100 includes a needle seat 102, a needle tube 101, a rear seat 103, a filter paper 104, a retaining ring 105, and a protective sleeve 106. The tooling strip 7 is long and narrow, and several piercing needles 100 are placed on the tooling strip 7. In this technical solution, there are several tooling strips, and several piercing needles 100 can be arranged along the length of each tooling strip. The direction of horizontal movement of the tooling strip is defined as horizontal transverse, and the horizontal direction perpendicular to the horizontal movement of the tooling strip is horizontal longitudinal. The conveying mechanism can drive the tooling strip to move horizontally and longitudinally. The conveying mechanism adopts cylinder or sprocket chain drive.

[0038] like Figure 3The needle-rolling device 15 includes at least one set of needle-rolling limiting mechanisms 21 and needle-rolling mechanisms 22. In this design, there are two sets of needle-rolling limiting mechanisms 21 and needle-rolling mechanisms 22, meaning there are two of each. The needle tube 101 is rolled twice using these two sets of mechanisms, thereby improving the accuracy and pass rate of the needle tube notch 1010 facing the set direction after needle rolling. Both the needle-rolling limiting mechanisms 21 and 22 are installed on the workbench 1 and are located on both sides of the tooling strip 7. 21 is used to abut against the notch 1010 of the needle tube 101 of the tooling strip to restrict the rotation of the needle tube 101; the needle rolling mechanism 22 is used to abut against the side wall of the needle tube 101 of the tooling strip and drive the needle tube 101 to reciprocate through friction, so that the needle rolling limiting mechanism 21 abuts against the notch 1010 of the needle tube 101; when the needle rolling limiting mechanism 21 abuts against the notch 1010 of the needle tube 101, the needle rolling mechanism 22 can no longer drive the needle tube 101 to rotate, and at this time the notch 1010 of the needle tube 101 faces the set direction.

[0039] The needle rolling mechanism 22 includes: a needle rolling translation drive 221, a needle rolling translation plate 222, a needle rolling translation drive 223, and a needle rolling plate 224. Both the needle rolling translation drive 221 and the needle rolling translation drive 223 are linear cylinders or linear motors. The needle rolling translation drive 221 is mounted on the worktable 1, and its drive end is connected to the needle rolling translation plate 222. The needle rolling translation plate 222 is slidably mounted on the worktable 1 via a slide rail slider. The needle rolling translation drive 221 drives the needle rolling translation plate 222 to move on the worktable 1 and move closer to or away from the tooling strip located at the needle rolling device 15. The needle rolling translation drive 223 is mounted on the needle rolling translation plate 222, and its drive end is connected to the needle rolling plate. 224. The needle rolling plate 224 is slidably mounted on the needle rolling translation plate 222 via a slide rail slider. The needle rolling translation drive component 223 is used to drive the needle rolling plate 224 to reciprocate along the length direction of the tooling strip, that is, to drive the needle rolling plate 224 to reciprocate along a direction parallel to the needle rolling limit plate 213. The needle rolling plate 224 is driven to abut against the side wall of the needle tube 101 inside the tooling strip by the needle rolling translation drive component 221, and then driven to reciprocate along the length direction of the tooling strip by the needle rolling translation drive component 223, so that the needle rolling plate 224 drives the needle tube 101 to rotate back and forth. The end of the needle rolling plate 224 is made of silicone or rubber material to increase the friction between the needle rolling plate 224 and the side wall of the needle tube 101, ensuring that the needle rolling plate 224 can drive the needle tube 101 to rotate.

[0040] The needle rolling limiting mechanism 21 includes: two needle rolling lifting support frames 211, two needle rolling lifting plates 212, and a needle rolling limiting plate 213. The two needle rolling lifting support frames 211 are installed on the workbench 1. Each needle rolling lifting support frame 211 is movably installed with a needle rolling lifting plate 212. The end of the needle rolling limiting plate 213 is rotatably disposed between the two needle rolling lifting plates 212 through a bearing. An angle micrometer is provided at the rotation point between the end of the needle rolling limiting plate 213 and the needle rolling lifting plate 212. The side end of the needle rolling limiting plate 213 is used to abut against the notch 1010 of the needle tube 101 located in the tooling strip 7.

[0041] The needle-rolling plate 224 moves back and forth along a direction parallel to the needle-rolling limiting plate 213, causing the needle-rolling plate 224 of the needle-rolling mechanism 22 to drive the needle tube 101 to rotate back and forth, thereby causing the notch 1010 of the needle tube 101 to abut against the needle-rolling limiting plate 213, so that the needle-rolling limiting plate 213 restricts the rotation of the needle tube 101, thereby making the notch 1010 of the needle tube 101 face the set direction.

[0042] The needle rolling lifting support frame 211 is provided with a needle rolling lifting strip hole 2111. Bolts pass through the needle rolling lifting strip hole 2111 and are connected to the side wall of the needle rolling lifting plate 212. The needle rolling lifting plate 212 is installed on the needle rolling lifting support frame 211 at different positions by the pressing fit between the needle rolling lifting strip hole 2111 and the bolt.

[0043] The needle-rolling device 15 also includes a lateral clamping mechanism 23, which is installed on the worktable 1 and used to abut against the two side walls of the tooling strip 7 to restrict the movement of the tooling strip. The lateral clamping mechanism 23 includes several lateral clamping drive components, which are cylinders or linear motors. The several lateral clamping drive components are distributed on opposite sides of the length of the tooling strip, and the drive end of the lateral clamping drive component is connected to a lateral clamping block. The lateral clamping block abuts against the side wall of the tooling strip under the drive of the lateral clamping drive component. By abutting against the opposite sides of the tooling strip, the movement of the tooling strip under the operation of the needle-rolling mechanism 22 is restricted, thereby ensuring the accuracy and pass rate of needle rolling.

[0044] The conveying mechanism moves the tooling strip from the gluing device 14 to the needle rolling device 15. The lateral clamping mechanism 23 abuts against the opposite sides of the tooling strip to limit the position of the tooling strip. The needle rolling limiting plate 213 abuts against the side wall of the needle tube 101. The needle rolling translation drive 1 221 drives the needle rolling translation plate 222 to approach the tooling strip. The needle rolling translation drive 223 drives the needle rolling plate 224 to move along the length direction of the tooling strip. That is, the needle rolling translation drive 223 drives the needle rolling plate 224 to move in a direction parallel to the needle rolling limiting plate 213, so that the needle rolling plate 224 drives the needle tube 101 to rotate, so that the notch 1010 of the needle tube 101 abuts against the side wall of the needle rolling limiting plate 213.

[0045] Because the spacing between the pin holder fixing molds on the tooling strip 7 is small, it is impossible to complete the upper back seat in one go by one upper back seat device 111. Therefore, this design scheme sets up two upper back seat devices 111 arranged side by side. One upper back seat device 111 is used to perform upper back seat on the pin holder fixing molds located at the first, third, fifth and other odd-numbered positions on the tooling strip 7, and the other one is used to perform upper back seat on the pin holder fixing molds located at the second, fourth and sixth even-numbered positions on the tooling strip 7.

[0046] Combination Figures 4-7 The upper rear seat device 111 includes: a rear seat hopper 31, a rear seat rotation mechanism 32, and a rear seat transfer pressing mechanism 33;

[0047] The rear seat hopper 31 is located on the side of the workbench 1. The rear seat hopper 31 includes a vibratory feeder 311 for storing the rear seats and a rear seat conveying guide rail 312 for conveying the rear seats. The rear seats are fed to the rear seat rotating mechanism 32 by driving the vibration of the vibratory feeder 311 and the rear seat conveying guide rail 312. The rear seat rotating mechanism 32 is located at the discharge end of the rear seat hopper 31. The rear seat transfer pressing mechanism 33 is installed on the workbench 1. The rear seat hopper 31 transports the rear seats to the rear seat rotating mechanism 32 through the rear seat conveying guide rail 312. The rear seat rotating mechanism 32 clamps the rear seats and rotates them at a set angle, that is, flips the rear seats 180 degrees. The rear seat transfer pressing mechanism 33 takes out the rear seats from the rear seat rotating mechanism 32 and moves the rear seats to the tooling strip located at the upper rear seat device 111. Then the rear seat transfer pressing mechanism 33 presses the rear seats onto the needle seat on the tooling strip.

[0048] like Figure 5 The rear seat rotation mechanism 32 includes: a rear seat lifting drive 321, a rear seat lifting plate 322, a rear seat rotation drive 323, a rear seat rotation plate 324, and a rear seat material handling mold 325. The rear seat lifting drive 321 is a linear cylinder or a linear motor, and is installed at the discharge end of the rear seat hopper 31. The drive end of the rear seat lifting drive 321 is connected to the rear seat lifting plate 322 to drive the rear seat lifting plate 322 to move up and down above the discharge end of the rear seat hopper 31. The rear seat rotation drive 323 is a rotary cylinder or a rotary motor, and is installed on the rear seat lifting plate 324. On 322, the drive end of the rear seat rotation drive 323 is connected to the rear seat rotation plate 324 to drive the rear seat rotation plate 324 to rotate. Several rear seat picking molds 325 are arranged on opposite sides of the rear seat rotation plate 324 along the length direction of the rear seat rotation plate 324. The rear seat picking molds 325 are used to insert into the bottom of the rear seat at the discharge end of the rear seat hopper 31 to take out the rear seat. The rear seat picking molds 325 are driven to move up and down by the rear seat lifting drive 321 to insert into the rear seat. The rear seat picking molds 325 are driven to flip by the rear seat rotation drive 323 to flip the rear seat so that the bottom of the rear seat faces the placement.

[0049] like Figure 6 The rear seat transfer pressing mechanism 33 includes: a rear seat transfer pressing bracket 331, a rear seat transfer pressing sliding plate 332, a rear seat transfer drive component 333, two rear seat transfer pressing lifting assemblies 334, a rear seat clamping assembly 335, and a rear seat transfer platform 336. The rear seat transfer pressing bracket 331 is mounted on the workbench 1, and the rear seat transfer drive component 333 is mounted on the rear seat transfer pressing bracket 331. The rear seat transfer drive component 333 is a linear motor or a cylinder. The drive end of the rear seat transfer drive component 333 is connected to the rear seat transfer pressing sliding plate 332 to drive the rear seat transfer pressing sliding plate 332 on the rear seat transfer pressing bracket 331. The rear seat transfer platform 336 is located on the workbench 1 next to the rear seat rotation mechanism 32. The rear seat transfer pressing and lifting assembly 334 is installed on the rear seat transfer pressing sliding plate 332, and each rear seat transfer pressing and lifting assembly 334 is equipped with a rear seat clamping assembly 335. The rear seat clamping assembly 335 is used to clamp the rear seat. One of the rear seat transfer pressing and lifting assemblies 334 is used to move the rear seat on the rear seat rotation mechanism 32 to the rear seat transfer platform 336, and the other rear seat transfer pressing and lifting assembly 334 is used to move the rear seat on the rear seat transfer platform 336 and press it onto the needle seat on the tooling strip.

[0050] The rear seat transfer pressing and lifting assembly 334 includes: a transfer pressing and lifting drive 3341 and a transfer pressing and lifting plate 3342. The transfer pressing and lifting drive 3341 is a linear cylinder or a linear motor. The transfer pressing and lifting drive 3341 is mounted on the rear seat transfer pressing sliding plate 332, and the drive end of the transfer pressing and lifting drive 3341 is connected to the transfer pressing and lifting plate 3342 to drive the transfer pressing and lifting plate 3342 to move up and down.

[0051] The rear seat clamping assembly 335 includes a rear seat clamping claw 3351 and a rear seat clamping mold 3352. Several rear seat clamping claws 3351 are arranged sequentially along the length of the lower end of the transfer pressing lifting plate 3342. Each rear seat clamping claw 3351 has a rear seat clamping mold 3352 installed on its clamping end. There are two rear seat clamping molds 3352 arranged opposite to each other. The rear seat clamping mold 3352 has a rear seat clamping groove 3353 adapted to the shape of the rear seat. The rear seat is clamped in the rear seat clamping groove 3353 by driving the two rear seat clamping molds 3352 to move closer to each other through the rear seat clamping claws 3351.

[0052] The upper rear seat device 111 also includes two needle straightening mechanisms 34, which are installed on the worktable 1 and respectively set on both sides of the tooling strip at the upper rear seat device 111, for respectively abutting against the opposite sides of the needle 101 on the tooling strip;

[0053] The needle alignment mechanism 34 includes a needle alignment and translation drive 341 and a needle alignment plate 342. The needle alignment and translation drive 341 is a linear cylinder or a linear motor. The needle alignment and translation drive 341 is mounted on the worktable 1, and the drive end of the needle alignment and translation drive 341 is connected to the needle alignment plate 342. One end of the needle alignment plate 342 of the needle alignment mechanism 34 has several needle alignment grooves 3421. The end of the needle tube straightening plate 342 of the tube straightening mechanism 34 is the needle tube straightening plane 3422. The needle tube is straightened by the cooperation of the needle tube straightening groove 3421 and the needle tube straightening plane 3422. That is, the needle tube is straightened by the needle tube being located between the needle tube straightening groove 3421 and the needle tube straightening plane 3422, and the needle tube straightening groove 3421 and the needle tube straightening plane 3422 abutting against the side wall of the needle tube, thereby ensuring the accuracy of the seat sleeve on the needle tube.

[0054] like Figure 7 The upper rear seat device 111 also includes two needle seat straightening mechanisms 35, which are installed at the lower end of the worktable 1. The straightening ends of the two needle seat straightening mechanisms 35 extend into the upper end of the worktable 1 and are respectively placed on both sides of the tooling strip at the upper rear seat device 111, for respectively abutting against the opposite sides of the needle seat fixing mold on the tooling strip.

[0055] The needle seat straightening mechanism 35 includes a needle seat straightening translation drive 351 and a needle seat straightening plate 352. The needle seat straightening translation drive 351 is a linear cylinder. The needle seat straightening translation drive 351 is installed at the lower end of the worktable 1. The needle seat straightening plate 352 is installed at the driving end of the needle seat straightening translation drive 351. The upper end of the needle seat straightening plate 352 passes through the worktable 1 and is placed next to the tooling strip. The end of the needle seat straightening plate 352 has several needle seat straightening grooves 3521. The needle seat straightening grooves 3521 are used to position and straighten the needle seat fixing mold on the tooling strip. The needle seat fixing mold is used to insert into the lower end of the needle seat to position and fix the needle seat. After the needle seat straightening grooves 3521 straighten the needle seat fixing mold, the needle seat can be straightened and the back seat can be aligned with the needle seat to achieve insertion, ensuring that the position of the back seat and the needle seat is accurate.

[0056] The rear seat hopper 31 loads material onto the rear seat rotating mechanism 32. The rear seat lifting drive 321 drives the rear seat lifting plate 322 to descend and approach the rear seat on the rear seat conveying guide rail 312, causing the rear seat picking mold 325 to insert into the rear seat. The rear seat lifting drive 321 then moves the rear seat upward. The rear seat rotating drive 323 drives the rear seat rotating plate 324 to rotate by a set angle, causing the rear seat picking mold 325 and the rear seat to rotate 180 degrees. The rear seat transfer drive 333 drives the rear seat transfer pressing sliding plate 332 to approach the rear seat rotating mechanism 32. The transfer pressing lifting drive 3341 drives the transfer pressing lifting plate 3342 to approach the rear seat on the rear seat picking mold 325, and the material clamping mechanism of the rear seat at the lower end of the transfer pressing lifting plate 3342 is also activated. The gripper 3351 clamps the rear seat through the rear seat clamping mold 3352, and the rear seat transfer drive 333 drives a rear seat transfer pressing and lifting assembly 334 to move the rear seat to the rear seat transfer platform 336. At the same time, it drives another rear seat transfer pressing and lifting assembly 334 to remove the rear seat from the rear seat transfer platform 336. Under the drive of the transfer pressing and lifting drive 3341, the rear seat is pressed onto the needle holder on the tooling strip. During the pressing of the rear seat onto the needle holder, the needle tube straightening and translation drive 341 drives the needle tube straightening plate 342 to abut against the side wall of the needle tube to ensure that the rear seat can be vertically fitted onto the needle tube. The needle holder straightening and translation drive 351 drives the needle holder straightening plate 352 to abut against the side wall of the needle holder to ensure that the position of the rear seat fitted onto the needle holder is accurate.

[0057] The back seat pressing device 112 presses the back seat tightly onto the needle seat, so that the needle seat and the back seat are connected and fixed by an interference fit.

[0058] like Figure 8 The tooling strip 7 of the conveying mechanism includes tooling strip one 71 and tooling strip two 72. Tooling strip one 71 moves sequentially and forms a cycle among the following devices: upper needle seat device 11, pressure needle seat device 12, upper needle tube device 13, glue application device 14, needle rolling device 15, drying device 16, blockage detection device 17, imaging device 18, silicone oil application device 19, waste rejection device 110, upper back seat device 111, pressure back seat device 112, upper sheath device 113, and pressure sheath device 114. Tooling strip two 72 moves sequentially and circulates among the following devices: transfer device 115, upper filter paper device 116, upper retaining ring device 117, defective product ejection device 118, and unloading device 119. Transfer device 115 is used to transfer the bottle-piercing needle 100 in tooling strip one 71 to tooling strip two 72.

[0059] The tooling strip 71 is equipped with a needle holder fixing mold. The needle holder is vertically fitted on the upper end of the needle holder fixing mold. The stability of the needle holder on the needle holder fixing mold is ensured by friction or interference fit. The tooling strip 72 is equipped with a workpiece placement groove 721. The workpiece placement groove 721 is used for horizontal placement of the bottle piercing needle 100, which facilitates the pressing and installation of filter paper and retaining ring on the side wall of the rear seat.

[0060] like Figure 8 The transfer device 115 includes: a transfer demolding mechanism 41, a transfer support frame 42, a transfer translation drive component 43, a transfer translation plate 44, a first transfer clamping assembly 45, a transfer flipping assembly 46, a transfer temporary storage table 47, and a second transfer clamping assembly 48.

[0061] The transfer demolding mechanism 41 is installed on the worktable 1. The transfer demolding mechanism 41 is used to demold the needle holders 100 on the tooling strip 71 from the fixed mold on the tooling strip 71. The transfer support frame 42 is installed on the worktable 1. The transfer translation drive 43 is a linear cylinder. The transfer translation drive 43 is installed on the transfer support frame 42. The transfer translation plate 44 is slidably set on the transfer support frame 42 via a slide rail slider. The drive end of the transfer translation drive 43 is connected to the transfer translation plate 44 to drive the transfer translation plate 44 to move on the transfer support frame 42. The transfer clamping assembly 45 is installed on the transfer translation plate 44. The tool 45 removes the bottle-piercing needle 100 from the tooling strip 71 and places it on the transfer flipping assembly 46. The transfer flipping assembly 46 and the transfer temporary storage platform 47 are both installed on the worktable 1. The transfer flipping assembly 46 flips the bottle-piercing needle 100 at a set angle and, with the cooperation of the transfer clamping assembly 48, temporarily stores the bottle-piercing needle 100 on the transfer temporary storage platform 47. The transfer temporary storage platform 47 is provided with several transfer temporary storage slots. The transfer temporary storage slots are used to store the bottle-piercing needle 100 after being flipped by the transfer flipping drive 461. The transfer clamping assembly 48 removes the bottle-piercing needle 100 from the transfer temporary storage platform 47 and places it into the workpiece placement slot 721 of the tooling strip 72.

[0062] Combination Figure 9 and Figure 11 The transfer demolding mechanism 41 includes: a transfer demolding drive component 411, a transfer demolding inclined block 412, a transfer demolding lifting plate 413, and a transfer demolding roller 414;

[0063] The transfer demolding drive 411 is a linear cylinder or a linear motor. Both the transfer demolding drive 411 and the transfer demolding inclined block 412 are mounted on the worktable 1. The transfer demolding lifting plate 413 is vertically slidably mounted on the drive end of the transfer demolding drive 411 via a slide rail slider. The lower front end of the transfer demolding lifting plate 413 has a first transfer demolding guide surface 4131. The upper front end of the transfer demolding lifting plate 413 has at least one demolding groove 4132. The upper rear end of the transfer demolding inclined block 412 is provided with a second transfer demolding guide surface 4121. The transfer demolding roller 414 is rotatably mounted on the worktable 1 via a bearing and is located next to the transfer demolding inclined block 412. The transfer demolding roller 414 is supported on the lower end of the transfer demolding lifting plate 413.

[0064] The transfer demolding drive 411 drives the transfer demolding lifting plate 413 to approach the transfer demolding inclined block 412 and the tooling strip 71, so that the needle 100 in the tooling strip 71 is placed in the demolding groove 4132. Then, the transfer demolding guide surface 4131 slides on the transfer demolding roller 414 and the transfer demolding guide surface 4121, so that the transfer demolding lifting plate 413 moves upward, thereby causing the transfer demolding lifting plate 413 to drive the needle 100 to move upward and demold from the tooling strip 71. This avoids the problem that the needle seat and the tooling strip 71 are too tightly connected after the upper back seat device 111 and the pressing back seat device 112 press the back seat into the needle seat, making demolding difficult. This ensures that the transfer clamping assembly 45 can take out the needle seat.

[0065] like Figure 10 The transfer gripping assembly 45 includes: a transfer gripping lifting drive 451 and a transfer gripping jaw 452; the transfer gripping lifting drive 451 is a linear cylinder or a linear motor, the transfer gripping lifting drive 451 is mounted on the transfer translation plate 44, and the transfer gripping jaw 452 is mounted on the drive end of the transfer gripping lifting drive 451. The transfer gripping jaw 452 is used to grip the needle 100 on the tooling strip 71.

[0066] The transfer and flip assembly 46 includes: a transfer and flip drive 461, a transfer and flip plate 462, and a transfer and flip gripper 463;

[0067] The transfer and flipping drive 461 is a motor or a rotary cylinder. The transfer and flipping drive 461 is mounted on the worktable 1. The drive end of the transfer and flipping drive 461 is connected to the transfer and flipping plate 462. The transfer and flipping drive 461 is used to drive the transfer and flipping plate 462 to rotate. The transfer and flipping plate 462 is provided with a transfer and flipping gripper 463. The transfer and flipping gripper 463 is used to grip the needle 100 transported by the transfer gripping assembly 45.

[0068] like Figure 10The transfer clamping assembly 2 48 includes: a transfer clamping lifting drive 2 481, a transfer picking rod 482, a transfer clamping unloading drive 483, a transfer clamping unloading plate 484, a transfer picking drive 485, and a transfer unloading plate 486.

[0069] The transfer clamping and lifting drive unit 481, the transfer picking drive unit 485, and the transfer clamping and unloading drive unit 483 are all linear cylinders or linear motors. The transfer clamping and lifting drive unit 481 is mounted on the transfer translation plate 44. The transfer picking drive unit 485, the transfer unloading plate 486, and the transfer clamping and unloading drive unit 483 are installed on the drive end of the transfer clamping and lifting drive unit 481. The transfer unloading plate 486 is located below the drive end of the transfer picking drive unit 485. The drive end of the transfer picking drive unit 485 is equipped with a transfer picking rod 482. The lower end of the transfer picking rod 482 passes through the transfer unloading plate 486. The clamping and unloading drive unit 483 is located beside the transfer picking rod 482. The drive end of the transfer clamping and unloading drive unit 483 is equipped with a transfer clamping and unloading plate 484. Under the drive of the transfer clamping and unloading drive unit 483, the transfer clamping and unloading plate 484 moves the bottle-piercing needle 100 clamped by the transfer flipping gripper 463 to the transfer temporary storage stage 47. The transfer picking rod 482 is used to insert the bottle-piercing needle 100 on the transfer temporary storage stage 47 and remove the bottle-piercing needle 100. Under the drive of the transfer translation drive unit 43, the transfer picking rod 482 moves to the top of the tooling strip 2 72 and puts the bottle-piercing needle 100 into the tooling strip 2 72.

[0070] The transfer demolding drive 411 drives the transfer demolding lifting plate 413 to approach the transfer demolding inclined block 412. The first transfer demolding guide surface 4131 slides on the second transfer demolding guide surface 4121, causing the transfer demolding lifting plate 413 to move upward and drive the needle seat to disengage from the needle seat fixing mold of the tooling strip 71. The transfer translation drive 43 drives the transfer clamping assembly 45 to be placed above the transfer demolding lifting plate 413. The transfer clamping lifting drive 451 drives the transfer clamping jaw 452 to lift and clamp the bottle-piercing needle 100 on the transfer demolding lifting plate 413, and then places it on the transfer flipping assembly 46. The transfer flipping drive 461 drives the transfer flipping plate 462 to rotate, thereby causing the transfer flipping jaw 463 to rotate 90 degrees, so that the bottle-piercing needle 100 rotates 90 degrees. At this time, the front half of the bottle-piercing needle 100 is located at the rotating plate. On the temporary storage platform 47, the transfer clamping and unloading drive 483 drives the transfer clamping and unloading plate 484 to move, thereby causing the transfer clamping and unloading plate 484 to drive the bottle-piercing needle 100 to move completely onto the temporary storage platform 47. The transfer clamping lifting drive 481 drives the transfer picking rod 482 to rise and fall, so that the transfer picking rod 482 is inserted into the rear seat and the bottle-piercing needle 100 is taken out. The transfer translation drive 43 drives the transfer clamping assembly 48 to move above the tooling strip 72. The transfer clamping lifting drive 481 drives the bottle-piercing needle 100 to move down and be placed into the tooling strip 72. The transfer picking drive 485 drives the transfer picking rod 482 to move up, so that the lower end of the transfer picking rod 482 retracts into the transfer unloading plate 486. The transfer unloading plate 486 separates the bottle-piercing needle 100 from the lower end of the transfer picking rod 482.

The upper filter paper sheet lifting drive 544 drives the upper filter paper sheet lifting plate 545 to move down, causing the upper filter paper rod 546 to extend into the punching positioning mold 535 to cooperate with the punching. The paper rod 533 is punched, and the upper filter paper rod 546 takes out the punched filter paper sheet and moves it to the rear seat on the tooling strip 72 under the drive of the upper filter paper sheet translation drive 542. The upper filter paper sheet lifting drive 544 drives the upper filter paper rod 546 to descend and load the filter paper sheet into the rear seat. The filter paper roll tightness detection mechanism 56 detects the tightness of the filter paper. The detection by the first detector 562 and the second detector 563 enables the control system to control the operation of the waste paper recycling drive 552, so that the waste paper recycling drive 552 drives the waste paper recycling roller 551 to rotate to collect waste paper.
