Description

Technical Field

[0001] This technical solution relates to the field of medical device manufacturing equipment technology, specifically to an upper filter paper device for a needle piercing assembly system. 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] To balance the air pressure inside and outside the container during liquid injection or extraction, the existing needle is equipped with an additional back seat with a venting channel. One through-hole of this venting channel extends into the container simultaneously with the needle tube, while the other through-hole remains outside the container. The external through-hole is fitted with a filter paper structure that allows only gas to pass through while blocking liquid, thus ensuring air pressure balance while preventing liquid leakage.

[0004] In the automated production of bottle-piercing needles, the filter paper needs to be punched through a filter paper feeding device before being assembled into the external through-hole of the rear assembly. However, existing filter paper feeding devices only have the functions of punching and feeding paper, lacking a recycling mechanism for the waste paper generated after punching: after punching the filter paper, the remaining waste paper (such as the edges and scraps after punching the filter paper roll) cannot be collected in time and can only accumulate at the punching station or on the conveying path of the device. This not only occupies the operating space of the device, but may also cause subsequent filter paper conveying to be stuck, punching positioning deviation due to waste paper accumulation, and even require frequent manual shutdowns for cleaning, seriously affecting the continuity of the filter paper feeding process and the overall assembly efficiency of the bottle-piercing needles. Summary of the Invention

[0005] The purpose of this technical solution is to provide a filter paper feeding device for a bottle needle assembly system. By setting a filter paper roll tightness detection mechanism, the tightness of the filter paper roll is detected, and the waste paper recycling mechanism collects the waste paper after flushing. This improves the problems caused by the lack of a waste paper recycling mechanism in the filter paper feeding device, which leads to waste paper accumulation, filter paper conveying jams, punching and positioning deviations, and the need for frequent manual shutdowns for cleaning, thus affecting assembly efficiency.

[0006] The purpose of this technical solution is achieved as follows:

[0007] A filter paper mounting device for a bottle-piercing needle assembly system includes:

[0008] Workbench, filter paper roll hopper, filter paper conveying wheel mechanism, paper flushing mechanism, filter paper feeding mechanism, waste paper recycling mechanism, filter paper roll tightness detection mechanism, guide rod;

[0009] A filter paper roll hopper is installed on the workbench. The hopper is used to hold filter paper rolls. A filter paper conveying wheel mechanism is installed on the workbench next to the hopper. This mechanism delivers the filter paper from the hopper to the flushing mechanism, which is also installed on the workbench. The flushing mechanism flushes the filter paper delivered by the conveying wheel mechanism. A filter paper feeding mechanism is installed on the workbench and feeds the flushed filter paper sheets into the bottle-piercing needle seat within the tooling strip. A filter paper roll tightness detection mechanism detects the tightness of the filter paper rolls and enables the waste paper recycling mechanism to collect the flushed waste paper.

[0010] The filter paper roll tightness detection mechanism includes: a detection bracket, a first detector, a second detector, and a lifting detection rod;

[0011] The detection bracket is installed on the workbench, and a detection strip groove is vertically set on the detection bracket. The first detector and the second detector are respectively installed on the upper half and the lower half of the detection strip groove. The end of the lifting detection rod is slidably placed in the detection strip groove and used to trigger the first detector or the second detector. The lifting detection rod is placed on the upper end of the filter paper between the filter paper roll hopper and the filter paper conveying wheel mechanism.

[0012] At least two guide rods are provided on the workbench. The two guide rods are located on both sides of the lifting detection rod and abut against the lower end face of the filter paper.

[0013] Preferably, the filter paper conveying wheel mechanism includes: a plurality of filter paper conveying wheel assemblies and a filter paper conveying wheel drive; the filter paper conveying wheel assembly includes two filter paper conveying rollers distributed vertically, with filter paper passing through between the two filter paper conveying rollers, and at least one filter paper conveying roller in at least one filter paper conveying wheel assembly is equipped with a filter paper conveying wheel drive at its end, and the filter paper conveying wheel drive drives the filter paper conveying roller to rotate to move the filter paper to a set position.

[0014] Preferably, the paper punching mechanism includes: a paper punching drive, a paper punching board, a paper punching rod, a paper punching positioning frame, and a paper punching positioning mold;

[0015] A paper-punching drive unit is installed on the workbench. The drive end of the paper-punching drive unit is connected to the paper-punching board. Several vertically arranged paper-punching rods are arranged sequentially along the length of the upper end of the paper-punching board. A paper-punching positioning frame is installed on the workbench and located on both sides of the paper-punching drive unit and the paper-punching board. A paper-punching positioning mold is installed on the upper end of the paper-punching positioning frame. The paper-punching positioning mold is provided with a paper-punching positioning groove for the filter paper to pass through and several paper-punching through holes for the paper-punching rods to pass through. The paper-punching through holes penetrate the upper and lower side walls of the middle part of the paper-punching positioning groove. The direction of movement of the filter paper in the paper-punching positioning groove is perpendicular to the direction of movement of the paper-punching rods in the paper-punching through holes.

[0016] The filter paper is moved into the punching positioning groove by the filter paper conveying wheel mechanism. The punching paper plate and punching rod are driven to move upward by the punching driving component, so that the end of the punching rod is inserted into the punching hole and abuts against the lower end face of the filter paper. It works in conjunction with the edge of the punching hole located at the upper end of the punching positioning groove to punch the filter paper into a filter paper sheet. The punching rod pushes the filter paper sheet out from the upper end of the punching hole at the upper end of the punching positioning groove and is taken out by the upper filter paper sheet mechanism.

[0017] Preferably, the upper filter paper mechanism includes: an upper filter paper support, an upper filter paper translation drive, an upper filter paper translation plate, an upper filter paper lifting drive, an upper filter paper lifting plate, and an upper filter paper rod;

[0018] The upper filter paper support is installed on the workbench. The upper filter paper translation drive is installed on the upper filter paper support, and the drive end of the upper filter paper translation drive is connected to and drives the upper filter paper translation plate to translate on the upper filter paper support. The upper filter paper lifting drive is installed on the upper filter paper translation plate, and the drive end of the upper filter paper lifting drive is connected to and drives the upper filter paper lifting plate to rise and fall on the upper filter paper translation plate. Several upper filter paper rods are arranged along the length of the upper filter paper lifting plate. The upper filter paper rods are used to pick up the filter paper pushed out by the flushing rod.

[0019] Preferably, the waste paper recycling mechanism includes: a waste paper recycling roller and a waste paper recycling drive component, both of which are mounted on a workbench, and the drive end of the waste paper recycling drive component is connected to the waste paper recycling roller.

[0020] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0021] This technical solution designs a filter paper roll tightness detection mechanism to detect the tightness of the filter paper roll and enables the waste paper recycling mechanism to collect the waste paper after flushing. This not only ensures stable tension during filter paper conveying and avoids conveying deviations caused by uneven filter paper roll tightness, but also enables waste paper recycling, avoiding waste paper accumulation problems. This improves the continuous operation capability of the filter paper feeding process, the punching and positioning accuracy, and the production efficiency of the bottle-piercing needle assembly line, while reducing manual cleaning steps, lowering labor costs and downtime losses.

[0027] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0028] Combination Figure 1 and Figure 2 A filter paper feeding device for a bottle needle assembly system includes a workbench 1, a filter paper roll hopper 51, a filter paper conveying wheel mechanism 52, a paper flushing mechanism 53, a filter paper feeding sheet mechanism 54, a waste paper recycling mechanism 55, and a filter paper roll tightness detection mechanism 56.

[0029] A tooling strip 7 is provided on the workbench 1, which is used to place bottle-piercing needles. A filter paper roll hopper 51 is installed on the workbench 1 and is used to install filter paper rolls. The filter paper roll hopper 51 has a filter paper roll support rod 511, which is rotatably mounted on the workbench 1 and rotatably connected to the filter paper roll. A filter paper conveying wheel mechanism 52 is installed on the workbench 1 and located beside the filter paper roll hopper 51. The filter paper conveying wheel mechanism 52 is used to pull out one end of the filter paper roll in the filter paper roll hopper 51 and send it to the paper flushing mechanism 53. The paper feeding mechanism 53 is installed on the workbench 1. The paper flushing mechanism 53 is used to flush the filter paper delivered by the filter paper conveying wheel mechanism 52 and form a circular filter paper sheet. The filter paper feeding mechanism 54 is installed on the workbench 1. The filter paper feeding mechanism 54 is used to feed the filter paper sheet flushed by the paper feeding mechanism 53 into the bottle-piercing needle seat in the tooling strip 7. The filter paper roll tightness detection mechanism 56 is used to detect the tightness of the filter paper roll and enable the waste paper recycling mechanism 55 to collect the waste paper after flushing. The waste paper recycling mechanism 55 rolls up the filter paper waste paper delivered by the paper flushing mechanism 53 to achieve waste paper recycling.

[0030] like Figure 2 and Figure 3 The filter paper conveying wheel mechanism 52 includes: a plurality of filter paper conveying wheel assemblies 521 and a filter paper conveying wheel drive 522; the filter paper conveying wheel assembly 521 includes two vertically distributed filter paper conveying rollers 5211, the ends of which are mounted on the worktable 1 via bearings, and filter paper passes through the space between the two filter paper conveying rollers 5211, and the filter paper is held between the two vertically distributed filter paper conveying rollers 5211; at least one filter paper conveying roller 5211 in at least one filter paper conveying wheel assembly 521 is equipped with a filter paper conveying wheel drive 522 at its end, and the filter paper conveying wheel drive 522 is a motor, which drives the filter paper conveying roller 5211 to rotate to move the filter paper to a set position.

[0031] like Figure 4 The paper punching mechanism 53 includes: a paper punching drive component 531, a paper punching plate 532, a paper punching rod 533, a paper punching positioning frame 534, and a paper punching positioning mold 535;

[0032] The paper-punching drive component 531 is a cylinder, which is mounted on the worktable 1. The drive end of the paper-punching drive component 531 is connected to the punching plate 532. Several vertically arranged paper-punching rods 533 are arranged sequentially along the length of the upper end of the punching plate 532. The paper-punching positioning frame 534 is mounted on the worktable 1 and located on both sides of the paper-punching drive component 531 and the punching plate 532. The upper end of the paper-punching positioning frame 534 is equipped with a paper-punching positioning mold 535. 35 is located above the paper-punching drive unit 531 and the paper-punching plate 532; the paper-punching positioning mold 535 is provided with a paper-punching positioning groove 5351 for filter paper to pass through and a plurality of paper-punching through holes 5352 for the paper-punching rod 533 to pass through. The paper-punching through holes 5352 penetrate the upper and lower side walls of the middle part of the paper-punching positioning groove 5351. The direction of movement of the filter paper in the paper-punching positioning groove 5351 is perpendicular to the direction of movement of the paper-punching rod 533 in the paper-punching through holes 5352.

[0033] The filter paper is moved into the punching positioning groove 5351 by the filter paper conveying wheel mechanism 52. The punching paper plate 532 and punching rod 533 are driven to move upward by the punching driving member 531, so that the end of the punching rod 533 is inserted into the punching hole 5352 and abuts against the lower end face of the filter paper. The punching driving member 531 further drives the punching rod 533 to move upward and cooperate with the lower edge of the punching hole 5352 located at the upper end of the punching positioning groove 5351 to punch the filter paper into a filter paper sheet. The punching rod 533 pushes the filter paper sheet out from the upper end of the punching hole 5352 at the upper end of the punching positioning groove 5351 and is taken out by the upper filter paper sheet mechanism 54.

[0034] The upper filter paper mechanism 54 includes: an upper filter paper support 541, an upper filter paper translation drive 542, an upper filter paper translation plate 543, an upper filter paper lifting drive 544, an upper filter paper lifting plate 545, and an upper filter paper rod 546.

[0035] The upper filter paper support 541 is installed on the workbench 1. The upper filter paper translation drive 542 is a cylinder. The upper filter paper translation drive 542 is installed on the upper filter paper support 541, and the drive end of the upper filter paper translation drive 542 is connected to and drives the upper filter paper translation plate 543 to translate on the upper filter paper support 541. The upper filter paper lifting drive 544 is a cylinder. The upper filter paper lifting drive 544 is installed on the upper filter paper translation plate 543, and the drive end of the upper filter paper lifting drive 544 is connected to and drives the upper filter paper lifting plate 545 to lift on the upper filter paper translation plate 543. Several upper filter paper rods 546 are arranged along the length of the upper filter paper lifting plate 545. The upper filter paper rods 546 are used to pick up the filter paper pushed out by the flushing rod 533.

[0036] When the paper-punching rod 533 moves upward so that the upper end of the filter paper abuts against the lower edge of the paper-punching through hole 5352 located at the upper end of the paper-punching positioning groove 5351, the lower end of the upper filter paper rod 546 extends into the paper-punching through hole 5352 located at the upper end of the paper-punching positioning groove 5351 and abuts against the upper end surface of the filter paper. That is, the paper-punching rod 533 and the upper filter paper rod 546 abut against the lower end and upper end surface of the filter paper, respectively. Then, the paper-punching rod 533 and the upper filter paper rod 546 move upward synchronously, so that the filter paper is punched out with the cooperation of the lower edge of the paper-punching through hole 5352, and the lower end of the upper filter paper rod 546 sucks the filter paper through the suction nozzle.

[0037] like Figure 3 The waste paper recycling mechanism 55 includes a waste paper recycling roller 551 and a waste paper recycling drive component 552. The waste paper recycling drive component 552 is a motor. Both the waste paper recycling roller 551 and the waste paper recycling drive component 552 are mounted on the workbench 1, and the drive end of the waste paper recycling drive component 552 is connected to the waste paper recycling roller 551 for driving the waste paper recycling roller 551 to rotate.

[0038] like Figure 2 and Figure 3The filter paper roll tightness detection mechanism 56 includes: a detection bracket 561, a first detector 562, a second detector 563, and a lifting detection rod 564. The first detector 562 and the second detector 563 are both detected by CCD (charge-coupled device), photoelectric sensor, infrared photodiode, or industrial camera. The detection bracket 561 is installed on the workbench 1, and a detection strip groove 5611 is vertically arranged on the detection bracket 561. The first detector 562 and the second detector 563 are respectively installed on the upper half and lower half of the detection strip groove 5611. The end of the lifting detection rod 564 is slidably placed in the detection strip groove 5611 and is used to trigger the first detector 562 or the second detector 563. The lifting detection rod 564 is placed on the upper end of the filter paper between the filter paper roll hopper 51 and the filter paper conveying wheel mechanism 52, and the filter paper is pressed down by the gravity of the lifting detection rod 564 itself.

[0039] When the filter paper tension between the waste paper recycling mechanism 55 and the filter paper conveying wheel mechanism 52 is lower than the first set value, the lifting detection rod 564 moves down in the detection strip groove 5611 and is detected by the second detector 563. The second detector 563 causes the control system to control the waste paper recycling mechanism 55 to collect waste paper, so that the filter paper tension between the waste paper recycling mechanism 55 and the filter paper conveying wheel mechanism 52 rises and is between the first set value and the second set value.

[0040] When the filter paper tension between the waste paper recycling mechanism 55 and the filter paper conveying wheel mechanism 52 is higher than the second set value, the lifting detection rod 564 rises in the detection strip groove 5611 and is detected by the first detector 562. The first detector 562 causes the control system to control the waste paper recycling mechanism 55 to stop working or slow down the waste paper collection speed, so that the filter paper tension between the waste paper recycling mechanism 55 and the filter paper conveying wheel mechanism 52 decreases and is between the first set value and the second set value.

[0041] One end of the filter paper roll in the filter paper roll hopper 51 extends out and passes through the filter paper conveying wheel mechanism 52, and then enters the waste paper recycling mechanism 55. The filter paper conveying wheel drive 522 drives the filter paper conveying roller 5211 to rotate, thereby moving the filter paper above the punching mechanism 53. Then, the punching drive 531 of the punching mechanism 53 drives the punching plate 532 and the punching rod 533 to punch holes in the filter paper located in the punching positioning mold 535. 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. The punching rod 533 punches holes, 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 7 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.

[0042] like Figure 3 Several guide rods 57 are rotatably mounted on the workbench 1 via bearings. The guide rods 57 abut against the filter paper to tighten the filter paper and guide the direction of movement of the filter paper.

[0043] At least two guide rods 57 are located on both sides of the detection strip groove 5611, and two guide rods 57 are located on both sides of the lifting detection rod 564; the two guide rods 57 move against the lower end surface of the filter paper, and the lifting detection rod 564 presses against the upper end surface of the filter paper by its own weight, thereby achieving tensioning of the filter paper.
