[0002] Push-type air-replenishing spray pumps are widely used in various medical drug delivery devices, such as nasal sprays and eye drop bottles. During use, the pump head is pressed to squeeze the liquid medicine out of the bottle. Existing drug delivery pump heads are equipped with a bacterial barrier membrane, primarily installed in the air inlet channel of the pump head structure, to prevent external dust, bacteria, and viruses from entering the pump body.

[0023] like Figure 2-19 As shown, an automatic assembly machine for a drug delivery pump head antibacterial membrane assembly includes a base 1 and a controller 2. A cam drive device 3 connected to the controller 2 is provided within the base 1. The cam drive device 3 provides driving force for the various mechanisms on the base 1. The base 1 is provided with a rotary transport mechanism 4 connected to the controller 2. A plurality of product fixtures 5 are circumferentially and evenly spaced on the rotary transport mechanism 4. An inner plug loading mechanism 6, a filter membrane loading mechanism 7, an outer shell loading mechanism 8, a pressing mechanism 9, a product inspection mechanism, and a blanking mechanism 10 are sequentially arranged on the base 1 along the direction of motion of the rotary transport mechanism 4.

[0025] The automatic assembly machine for the antibacterial membrane component of the dosing pump head can automatically cut the filter membrane and automatically complete the assembly of the inner plug, filter membrane and outer shell, thereby automatically completing the assembly of the antibacterial touch component without the need for human participation, greatly improving the efficiency of assembly; using machines instead of manual labor reduces labor costs; and through the product testing agency to test the product on the product fixture 5, the yield rate of assembly can be greatly improved.

[0026] The controller 2 controls the operation of each mechanism to realize the automated processing process. Figure 2As shown, in this embodiment, the controller 2 includes a touch screen 21 and multiple control buttons 22. A protective cover 11 is sleeved onto the outside of the base 1. This cover 11 fits around the periphery of each mechanism, allowing for relatively closed processing and preventing dust and other particles from entering the moving components of the device. The protective cover 11 is equipped with multiple openable doors 12, allowing operators to observe the device's operation by opening them, facilitating maintenance and adjustments.

[0027] The rotary material transport mechanism 4 comprises a material transport drive mechanism and a turntable 41. The material transport drive mechanism is fixedly mounted on the machine base 1. The turntable 41 is rotatably connected to the machine base 1. The output end of the material transport drive mechanism is connected to the turntable 41. All product jigs 5 are fixedly mounted on the turntable 41. During operation, the material transport drive mechanism drives the turntable 41 to rotate, thereby moving the product jigs 5 to their respective processing positions. The material transport drive mechanism can adopt any existing device capable of driving rotational motion, such as a motor divider structure.

[0028] like Figure 5 As shown, the inner plug feeding mechanism 6 includes a first vibrating disk 61, a first oscillator 62, and an inner plug picking robot 63. The first vibrating disk 61 and the first oscillator 62 are respectively connected to the machine base 1. The output end of the first vibrating disk 61 is connected to the input end of the first oscillator 62, and the inner plug picking robot 63 is connected to the output end of the first oscillator 62. The inner plug picking robot 63 is connected to the cam drive device 3, and the cam drive device 3 can drive the inner plug picking robot 63 to move up and down. Before processing, the operator can first pour the inner plug onto the first vibrating disk 61. The operation of the first vibrating disk 61 can orderly transport the inner plug to the first oscillator 62. The operation of the first oscillator 62 then orderly transports the inner plug to the grabbing position of the inner plug picking robot 63. The inner plug picking robot 63 and the cam drive device 3 cooperate to grab the inner plug and place it on the product jig 5 on the rotating material transport mechanism 4, thereby realizing the automatic feeding process of the inner plug.

[0029] The first vibrating plate 61 can be any existing vibrating plate, and the first oscillator 62 can also be any existing oscillator. The machine base 1 is provided with an inner plug stopper 64, which is located at the end of the first oscillator 62 away from the first vibrating plate 61 and is used to receive the inner plug output by the first oscillator 62. The inner plug removal robot 63 can remove the inner plug from the inner plug stopper 64, thereby completing the loading process. The inner plug stopper 64 can limit the inner plug, making it easier for the inner plug removal robot 63 to grab it when it is stationary, thereby improving the stability of the processing.

[0030] The inner plug picking robot 63 includes a first fixed seat 631, which is slidably limitedly connected to the machine base 1, and the first fixed seat 631 is connected to the cam drive device 3. The cam drive device 3 can drive the first fixed seat 631 to move up and down. The first fixed seat 631 is provided with a first slide rail 632 and a first picking cylinder 633. The first slide rail 632 is slidingly provided with a first picking mounting seat 634. The first picking mounting seat 634 is connected to the output end of the first picking cylinder 633. The first picking mounting seat 634 is provided with an inner plug suction head 635. The inner plug suction head 635 is externally connected to a negative pressure device. The first picking cylinder 633 can drive the inner plug suction head 635 to move back and forth between the first oscillator 62 and the product fixture 5. During processing, after the first vibrator 62 transports the inner plug to the inner plug limiting seat 64; the first material picking cylinder 633 drives the first material picking mounting seat 634 to slide on the first slide rail 632 until the first material picking mounting seat 634 moves to just above the inner plug limiting seat 64; the cam driving device 3 then drives the first fixed seat 631 and the first material picking mounting seat 634 to descend until the inner plug suction head 635 on the first material picking mounting seat 634 is connected with the inner plug on the inner plug limiting seat 64, and a negative pressure suction force is generated by the external negative pressure device on the inner plug suction head 635, so that the inner plug is sucked The head 635 can absorb the inner plug; then the cam driving device 3 drives the first fixed seat 631 and the first material picking mounting seat 634 to rise, so that the inner plug suction head 635 sucks up the inner plug; then the first material picking mounting seat 634 is driven by the first material picking cylinder 633 to move in the direction close to the product fixture 5, until the first material picking mounting seat 634 drives the inner plug suction head 635 to move to the top of the product fixture 5, and then the cam driving device 3 and the inner plug suction head 635 cooperate to place the inner plug on the product fixture 5 on the rotating material transport mechanism 4, completing the inner plug loading work.

[0031] like Figure 4 、 Figure 6As shown, the machine base 1 is provided with an inner plug detection mechanism 15, which is arranged on one side of the inner plug feeding mechanism 6 and is used to detect whether the product jig 5 has an inner plug. The rotating material transport mechanism 4 can drive the product jig 5 with the inner plug placed thereon to the corresponding position of the inner plug detection mechanism 15. The inner plug detection mechanism 15 then detects whether the product jig 5 has an inner plug, thereby determining whether the inner plug feeding mechanism 6 has successfully loaded the product, thereby ensuring the processing yield rate.

[0032] Specifically, the plug detection mechanism 15 includes an plug detection fixed seat 151, which is connected to the machine base 1, and an plug detection cylinder 152 is provided on the plug detection fixed seat 151. An plug detection mounting block 153 is provided on the output end of the plug detection cylinder 152, and a contact sensor 154 is provided on the plug detection mounting block 153. The contact sensor 154 is connected to the controller 2, and the plug detection cylinder 152 can drive the contact sensor 154 to move towards or away from the product fixture 5.

[0033] During processing, after the inner plug is loaded onto the product jig 5 by the inner plug loading mechanism 6, the product jig 5 is driven to move by the rotating material transport mechanism 4, thereby transferring the product jig 5 with the inner plug placed thereon to directly below the contact sensor 154. The inner plug detection cylinder 152 then drives the inner plug detection mounting block 153 and the contact sensor 154 downward. When the inner plug detection cylinder 152 is driven to its limit position, the contact sensor 154 contacts the inner plug on the product jig 5. At this point, the contact sensor 154 sends a feedback signal to the controller 2, indicating that there is an inner plug on the product jig 5. Conversely, if there is no inner plug on the product jig 5, the contact sensor 154 does not send a feedback signal to the controller 2. The controller 2 then determines that there is no inner plug on the current product jig 5 and can adaptively control subsequent workstations to not process the product jig 5, thereby reducing material waste and improving processing efficiency. After the detection is completed, the inner plug detection cylinder 152 is controlled to reset, driving the inner plug detection mounting block 153 to drive the contact sensor 154 to move away from the product fixture 5, and then the product fixture 5 is transported to the next workstation through the rotating material conveying mechanism 4.

[0034] like Figure 7As shown, the membrane loading mechanism 7 is used to cut the roll of filter membrane into preset sizes and place it on the inner plug of the product jig 5 on the rotary conveyor mechanism 4. The rotary conveyor mechanism 4 can transport the product jig 5 with the inner plug placed thereon to the loading position of the membrane loading mechanism 7. The membrane loading mechanism 7 includes a membrane cutting assembly 71, a membrane receiving assembly 72, and a membrane retrieving manipulator 73, each of which is connected to the controller 2. The membrane cutting assembly 71 is connected to the machine base 1 and is used to cut the entire roll of filter membrane into preset sizes. The membrane receiving assembly 72 is connected to the membrane cutting assembly 71 and is used to receive the filter membrane cut by the membrane cutting assembly 71 and transport the filter membrane to the corresponding position of the membrane retrieving manipulator 73. The membrane retrieving manipulator 73 is connected to the cam drive device 3. The membrane retrieving manipulator 73 is used to suck the filter membrane from the membrane receiving assembly 72 and place the filter membrane on the inner plug of the product jig 5.

[0035] Before processing, the entire roll of filter membrane can be placed on the filter membrane cutting assembly 71; during processing, the product jig 5 with the inner plug placed thereon is transported to the corresponding position of the filter membrane picking manipulator 73 by the rotating material transport mechanism 4, and then the filter membrane cutting assembly 71 is controlled to cut the entire roll of filter membrane into a preset size, and the cut filter membrane will automatically fall onto the filter membrane receiving assembly 72; the filter membrane receiving assembly 72 is used to transport the cut filter membrane to the corresponding position of the filter membrane picking manipulator 73, and then the filter membrane picking manipulator 73 sucks the filter membrane on the filter membrane receiving assembly 72 and places the filter membrane on the inner plug on the product jig 5, thereby completing the filter membrane cutting and feeding process. Through the cooperation of the filter membrane picking assembly 72 and the filter membrane picking manipulator 73, the cut filter membrane can be automatically fed to the product jig 5, so that it can meet the processing requirements of automated assembly, improve the degree of automation of the antibacterial membrane assembly automatic assembly machine, and improve the assembly efficiency of the antibacterial membrane assembly.

[0036] like Figure 7As shown, the filter membrane cutting assembly 71 includes a cutting fixed seat 711, which is fixedly mounted on the machine base 1. The cutting fixed seat 711 is provided with a film pulling mechanism and a punching mechanism 74. The film pulling mechanism is provided with a feed roller 712. The feed roller 712 is used to place the roll filter membrane to be punched. The roll filter membrane can be stretched and laid on the punching mechanism 74 and the film pulling mechanism. The film pulling mechanism is used to pull the roll filter membrane. The punching mechanism 74 can be connected to the roll filter membrane to punch the roll filter membrane into a preset size. During specific processing, the roll filter membrane is placed on the feed roller 712 and stretched and laid on the punching mechanism 74 and the film pulling mechanism in sequence; by controlling the operation of the punching mechanism 74, the roll filter membrane can be punched into a preset shape and size. After punching, the film pulling mechanism can drive the roll filter membrane to move, thereby laying a new roll filter membrane on the punching position of the punching mechanism 74, so that the punching mechanism 74 can achieve continuous punching. The filter membrane feeding mechanism 7 can automatically and continuously cut the roll filter membrane through the cooperation of the film pulling mechanism and the punching mechanism 74 without manual intervention, thereby improving the automation level of the equipment, reducing labor costs, and improving processing efficiency.

[0037] like Figure 9 、 Figure 10 As shown, the punching mechanism 74 includes a punching fixture 741, which is fixedly mounted on the cutting fixture 711. A punching cylinder 742 is fixedly mounted on the punching fixture 741. Four punching needles 743 are mounted on the output end of the punching cylinder 742. Punching holes 744 are respectively provided on the punching fixture 741 at positions corresponding to the punching needles 743. Through the cooperation of the four punching needles 743 and the punching holes 744, the punching mechanism 74 can punch out four filter membranes of pre-stored sizes in one operation, thereby improving processing efficiency. The roll filter membrane can be laid on the upper end surface of the punching hole 744. The punching cylinder 742 can drive the punching needles 743 to extend into or out of the punching hole 744. The filter membrane material receiving assembly 72 is arranged below the punching hole 744. During specific operation, after the roll filter membrane is placed on the feeding roller 712, one end of the roll filter membrane will be pulled and laid on the punching fixing seat 741 and the film pulling mechanism in sequence, so that the roll filter membrane covers each punching hole 744 respectively; by controlling the punching cylinder 742 to work, the punching needle 743 is driven to descend, so that the punching needle 743 is connected with the roll filter membrane and squeezes the roll filter membrane; as the punching needle 743 descends, it will extend into the punching hole 744, and the punching needle 743 cuts the roll filter membrane into a size that matches the end face of the punching needle 743, and enters the punching hole 744 with the cut filter membrane. After the cut filter membrane enters the punching hole 744, it will fall onto the filter membrane receiving assembly 72 due to its own gravity; then the punching cylinder 742 is controlled to reset, and the punching needle 743 is driven to rise and extend out of the punching hole 744 to reset to its initial position.

[0038] In order to limit and guide the lifting and lowering movement direction of the punching needle 743, two punching guide rods 745 are installed on the punching fixed seat 741, and a punching needle mounting seat 746 is provided on the output end of the punching cylinder 742. The punching needle 743 is fixedly mounted on the punching needle mounting seat 746. The punching guide rods 745 pass through the punching needle mounting seat 746 and are slidably connected to the punching needle mounting seat 746. When the punching cylinder 742 is working, it will drive the punching needle mounting seat 746 and the punching needle 743 to move, and the punching needle mounting seat 746 slides on the punching guide rods 745. The cooperation between the punching needle mounting seat 746 and the punching guide rods 745 can limit and guide the movement direction of the punching needle 743, thereby ensuring that the punching needle 743 can be lifted and lowered in a straight line, so that it can be smoothly inserted into the punching hole 744 to complete the punching work of the filter membrane. This can not only improve the punching efficiency, but also avoid the punching needle 743 from colliding and breaking, thereby improving the processing stability.

[0039] In order to prevent the roll filter membrane from warping and deforming during punching, a punching pressing block 747 is provided on the punching fixing seat 741. The punching pressing block 747 is movably matched with the punching fixing seat 741. A needle hole 748 is provided at the corresponding position of the punching pressing block 747 and the punching hole 744. A pressing guide rod 749 is provided on the punching pressing block 747. The pressing guide rod 749 passes through the punching needle mounting seat 746 and is matched with the punching needle mounting seat 746 for sliding limit. The punching cylinder 742 can drive the punching needle 743 to pass through the needle hole 748. During processing, the rolled filter membrane is stretched and laid through the gap between the punching fixing seat 741 and the punching pressing block 747, and the weight of the punching pressing block 747 itself will press and cover the rolled filter membrane; during the punching process, the punching cylinder 742 works to drive the punch needle 743 to descend, and the punch needle 743 will slide in the needle hole 748, and the punch needle mounting seat 746 slides on the pressing guide rod 749, and the rolled filter membrane is pressed by the punching pressing block 747, which can prevent the rolled filter membrane from curling up and deforming, ensure that the punch needle 743 can smoothly cut the filter membrane, and improve the stability of the processing; moreover, by arranging a needle hole 748 on the punching pressing block 747 to cooperate with the punch needle 743, the movement direction of the punch needle 743 can also be limited, further improving the stability of the processing.

[0040] like Figure 7As shown, the film-drawing mechanism includes a film-drawing mounting frame 713, which is slidably connected to a cutting fixed seat 711. A drawing roller 714 and a recovery roller 715 are mounted on the film-drawing mounting frame 713. The feed roller 712, the drawing roller 714, and the recovery roller 715 are rotatably connected to the film-drawing mounting frame 713. The drawing roller 714 is used to pull the roll filter membrane to move on the film-drawing mounting frame 713, and the recovery roller 715 is used to rewind the waste roll filter membrane after cutting. The roll filter membrane on the feed roller 712 can be laid on the drawing roller 714 and the recovery roller 715 in sequence. The film-drawing mounting frame 713 is provided with a film-drawing drive assembly, which is respectively connected to the drawing roller 714 and the recovery roller 715 to drive the drawing roller 714 and the recovery roller 715 to rotate on the film-drawing mounting frame 713. Before processing, the roll filter membrane is first hung on the feeding roller 712; then one end of the roll filter membrane is pulled to pass through the gap between the punching fixing seat 741 and the punching pressing block 747, and then stretched and laid on the drawing roller 714 and the recovery roller 715 respectively; during processing, when the punching mechanism 74 has punched the roll filter membrane, the film pulling drive assembly is controlled to work, and the drawing roller 714 and the recovery roller 715 are driven to rotate respectively. The drawing roller 714 will pull the roll filter membrane on the feeding roller 712 toward the drawing roller 714, so that the new roll filter membrane is laid on the punching hole 744, and the recovery roller 715 can rotate to rewind the waste roll filter membrane after punching.

[0041] like Figure 7 、 Figure 8 As shown, in this embodiment, the film-drawing drive assembly includes a film-drawing motor 716, which is fixedly mounted on a film-drawing mounting frame 713. A film-drawing active wheel 717 is mounted on the output end of the film-drawing motor 716, a film-drawing driven wheel 718 is mounted on one end of a material-drawing roller 714, and a recovery driven wheel 719 is mounted on one end of a recovery roller 715. A film-drawing transmission belt 7110 is sleeved on the film-drawing active wheel 717 and the film-drawing driven wheel 718, and a recovery transmission belt 7111 is sleeved on the recovery driven wheel 719 and the film-drawing driven wheel 718. By providing the film-drawing transmission belt 7110 and the recovery transmission belt 7111, the film-drawing motor 716 can simultaneously drive the material-drawing roller 714 and the recovery roller 715 to rotate synchronously, thereby achieving the functions of drawing the roll filter film and recovering the roll filter film waste. In other embodiments, other structural devices for achieving rotational drive can also be used, such as a motor gear structure.

[0042] like Figure 8As shown, a cutting transverse shift assembly 75 is provided on the cutting fixture 711. The output end of the cutting transverse shift assembly 75 is connected to the film-pulling mounting frame 713. The cutting transverse shift assembly 75 is used to drive the film-pulling mounting frame 713 to move laterally on the cutting fixture 711, thereby driving the roll filter membrane to move laterally on the punching fixture 741. Because the width of the roll filter membrane is much larger than the sum of the diameters of the four filter membranes punched by the punching needle 743, the cutting transverse shift assembly 75 is provided to drive the roll filter membrane to move laterally. This allows the unpunched roll filter membrane to align with the punching holes 744, thereby improving the material utilization of the roll filter membrane, reducing waste generation, and saving costs. In actual operation, the cutting transverse shift assembly 75 is controlled to operate once, which controls the punching mechanism 74 to punch once. After the utilization rate of the roll filter membrane is maximized, the film-pulling motor 716 is controlled to drive the pulling roller 714 to pull the roll filter membrane. According to the different widths of the roll filter membrane, the number of operations of the cutting and transverse movement assembly 75 can be adaptively adjusted.

[0043] In this embodiment, the cutting and transverse movement assembly 75 includes a transverse movement motor 751, which is connected to the cutting fixed seat 711. The output end of the transverse movement motor 751 is provided with a transverse movement screw 752, and the transverse movement slider 753 is sleeved on the transverse movement screw 752. The transverse movement slider 753 is connected to the film-drawing mounting frame 713. During operation, the transverse movement motor 751 drives the transverse movement screw 752 to rotate, thereby driving the transverse movement slider 753 to slide on the transverse movement screw 752. The transverse movement slider 753 drives the film-drawing mounting frame 713 to move synchronously, allowing the roll filter film to move horizontally on the punching fixed seat 741, thereby aligning the uncut roll filter film with the punching hole 744.

[0044] To limit and guide the movement of the film-drawing mounting frame 713, a transverse guide block 754 is provided on the film-drawing mounting frame 713, and a transverse guide rail 755 is provided on the cutting fixture 711. The transverse guide block 754 and the transverse guide rail 755 are slidably engaged. The cooperation between the transverse guide block 754 and the transverse guide rail 755 limits and guides the movement of the film-drawing mounting frame 713, ensuring that the roll filter membrane can move laterally on the punching fixture 741, thereby improving transmission accuracy and processing stability.

[0045] like Figure 7 、 Figure 11As shown, the filter membrane material receiving assembly 72 includes a material receiving fixing plate 721, which is fixedly connected to the cutting fixing seat 711, and a material receiving transverse movement cylinder 722 and a material receiving guide rail 723 are provided on the material receiving guide rail 723, and a material receiving mounting block 724 is slidingly provided on the material receiving mounting block 724, and a material receiving lifting cylinder 725 is provided on the material receiving mounting block 724, and a material receiving block 726 is provided on the output end of the material receiving lifting cylinder 725, and the material receiving mounting block 724 is connected to the output end of the material receiving transverse movement cylinder 722, and a material receiving groove 727 is provided on the material receiving block 726 at a position corresponding to the punching hole 744, and the material receiving groove 727 is externally connected to a negative pressure device. The material receiving transverse movement cylinder 722 can drive the material receiving block 726 to be connected to the punching fixed seat 741 or the filter membrane material taking robot 73 respectively, and the material receiving lifting cylinder 725 can drive the material receiving block 726 to move up and down, thereby driving the material receiving trough 727 to connect or separate with the punching hole 744.

[0046] In the initial state, the material receiving transverse movement cylinder 722 is retracted, and the material receiving block 726 is located directly below the punching fixed seat 741; the material receiving lifting cylinder 725 is in the extended state, so that the material receiving trough 727 is connected to the punching hole 744 and is located directly below the punching hole 744. During processing, when the punching mechanism 74 completes the punching of the filter membrane, the punched filter membrane will fall through the punching hole 744 into each material receiving trough 727; the negative pressure device externally connected to the material receiving trough 727 ensures that the filter membrane is attracted to the material receiving trough 727. Afterwards, the material receiving lifting cylinder 725 is controlled to retract, so that the material receiving trough 727 is separated from the punching hole 744; then, the material receiving transverse movement cylinder 722 is controlled to extend, driving the material receiving mounting block 724 to slide on the material receiving guide rail 723, and the material receiving mounting block 724 drives the material receiving lifting cylinder 725, the material receiving block 726 and the filter membrane to move together until the material receiving block 726 moves to the loading position of the filter membrane picking robot 73; then, the filter membrane is sucked from the material receiving trough 727 by the filter membrane picking robot 73, and the filter membrane is guided to the product fixture 5, completing the filter membrane feeding process. After the membrane picking robot 73 picks up the membrane from the receiving trough 727, the receiving transverse movement cylinder 722 is controlled to retract and reset, driving the receiving block 726 to move to the initial position; then the receiving lifting cylinder 725 is controlled to extend, driving the receiving block 726 to rise until the receiving trough 727 is connected with the punching hole 744 for the next round of membrane punching processing.

[0047] In this embodiment, the receiving block 726 is provided with four receiving slots 727, each of which is connected to a negative pressure device, and the receiving slots 727 are arranged in a one-to-one correspondence with the punching holes 744. In other embodiments, the number of receiving slots 727 can also be adjusted according to the number of punching holes 744 and punching needles 743.

[0048] In order to limit the movement of the material receiving mounting block 724, two material receiving buffers 728 are installed on the material receiving fixing plate 721. The material receiving mounting block 724 can respectively abut against the two material receiving buffers 728. In the initial state, the material receiving mounting block 724 abuts against one of the material receiving buffers 728. At this time, the material receiving groove 727 on the material receiving block 726 is exactly aligned with the corresponding punching hole 744. When the material receiving transverse movement cylinder 722 is in operation, it drives the material receiving mounting block 724 to slide on the material receiving guide rail 723 until the material receiving mounting block 724 abuts against the other material receiving buffer 728. At this time, the material receiving mounting block 724 drives the material receiving block 726 to move to the loading position of the filter membrane material taking robot 73. By setting up two material receiving buffers 728, the movement stroke of the material receiving mounting block 724 can be limited, ensuring that the material receiving mounting block 724 can drive the material receiving block 726 to accurately move to the corresponding position of the punching hole 744 and the loading position of the filter membrane material taking robot 73.

[0049] like Figure 7 、 Figure 12As shown, the filter membrane picking robot 73 includes a second fixed seat 731, which is slidably limitedly connected to the machine base 1, and the second fixed seat 731 is connected to the cam driving device 3. The cam driving device 3 can drive the second fixed seat 731 to move up and down, and the second fixed seat 731 is provided with a second slide rail 732 and a second picking cylinder 733. The second slide rail 732 is slidably provided with a second picking mounting seat 734, and the second picking mounting seat 734 is connected to the output end of the second picking cylinder 733. The second picking mounting seat 734 is provided with a filter membrane suction head 735, and the filter membrane suction heads 735 are respectively connected to an external negative pressure device. The second picking cylinder 733 can drive the filter membrane suction head 735 to move back and forth between the receiving block 726 and the product fixture 5. After the filter bag 730 is in the working state, the filter bag 730 is put into the working state, and the filter bag 730 is put into the working state. After the filter bag 730 is in the working state, the filter bag 730 is put into the working state, and the filter bag 730 is put into the working state. 731 rises, driving the material taking mounting seat and the filter membrane suction head 735 to rise together, so that the filter membrane suction head 735 is separated from the material receiving block 726; then, by controlling the operation of the second material taking cylinder 733, the material taking mounting seat is driven to slide on the second slide rail 732, and the material taking mounting seat drives the filter membrane suction head 735 and the filter membrane to move synchronously until the filter membrane suction head 735 moves to just above the product fixture 5; then, the second fixed seat 731 is driven to descend by the cam drive device 3, driving the material taking mounting seat, the filter membrane suction head 735 and the filter membrane to descend together until the filter membrane suction head 735 is connected to the product fixture 5; then the negative pressure suction on the filter membrane suction head 735 is disconnected, and the filter membrane on the filter membrane suction head 735 will automatically fall onto the product on the product fixture 5, completing the filter membrane feeding process.

[0050] In this embodiment, there are four filter membrane suction heads 735, and the four filter membrane suction heads 735 are arranged in a one-to-one correspondence with the material receiving grooves 727 on the material receiving block 726; in other embodiments, the filter membrane suction heads 735 can also be any other number.

[0051] like Figure 13As shown, the shell loading mechanism 8 is used to transport the shell to the product jig 5 on the rotating material conveying mechanism 4 and place the shell on the inner plug on the product jig 5. The shell loading mechanism 8 includes a second vibrating disk 81, a second straight vibrator 82 and a shell picking robot 83. The second vibrating disk 81, the second straight vibrator 82 and the shell picking robot 83 are respectively connected to the controller 2. The second vibrating disk 81 and the second straight vibrator 82 are respectively fixedly mounted on the machine base 1. The output end of the second vibrating disk 81 is connected to the input end of the second straight vibrator 82. The shell picking robot 83 is connected to the output end of the second straight vibrator 82. The shell picking robot 83 is movably connected to the machine base 1. The shell picking robot 83 is connected to the cam driving device 3, and the cam driving device 3 can drive the shell picking robot 83 to move up and down. The shell picking robot 83 is used to grab the shell and place it on the product jig 5.

[0052] During processing, the operator pours the shells onto the second vibrating plate 81. The second vibrating plate 81 then operates to orderly transport the shells to the second straight vibrator 82. The second straight vibrator 82 then operates to orderly transport the shells to the external gripping position of the shell retrieving manipulator 83. The shell retrieving manipulator 83 and the cam drive 3 work together to grab the shells onto the product jig 5 on the rotary conveyor mechanism 4, thus achieving automatic shell loading. This shell loading mechanism 8 can automatically feed shells to the antibacterial film assembly machine, thereby improving the equipment's degree of automation and reducing labor costs. The use of a mechanical structure to achieve automated loading meets the needs of automated processing, thereby improving processing efficiency.

[0053] like Figure 13 As shown, in this embodiment, a pre-positioning component 84 is provided between the second straight vibrator 82 and the shell picking robot 83. The pre-positioning component 84 is used to receive the shell sent out by the second straight vibrator 82 and limit the shell so that the shell picking robot 83 can better grasp the shell; the pre-positioning component 84 is respectively connected to the output end of the second straight vibrator 82 and the shell picking robot 83, and the shell picking robot 83 can grasp the shell from the pre-positioning component 84.

[0054] like Figure 14As shown, specifically, the pre-positioning assembly 84 includes a pre-positioning fixing seat 841, which is fixedly connected to the machine base 1. The second straight vibrator 82 is provided with a shell feeding trough 821. The second straight vibrator 82 is capable of driving the shell to slide along the shell feeding trough 821. A feeding trough 842 is provided at a position corresponding to the shell feeding trough 821 on the pre-positioning fixing seat 841. Both ends of the shell feeding trough 821 are connected to the output end of the second vibration plate 81 and the feeding trough 842. In specific operation, the second vibration plate 81 is capable of conveying the shells to the shell feeding trough 821 in sequence. The second straight vibrator 82 is capable of driving the shells to slide in the shell feeding trough 821, so that the shells move to one end of the shell feeding trough 821 close to the pre-positioning fixing seat 841. As the second straight vibrator 82 continues to work, the shells behind will push the shells in front and push them into the feeding trough 842, so that the shells enter the pre-positioning fixing seat 841.

[0055] A pre-positioning cylinder 843 and a pre-positioning slider 844 are provided on the pre-positioning fixing seat 841. The pre-positioning cylinder 843 is fixedly connected to the pre-positioning fixing seat 841, and the pre-positioning slider 844 is slidably connected to the pre-positioning fixing seat 841, and the side wall of the pre-positioning slider 844 is connected to the pre-positioning fixing seat 841; a pre-positioning groove 845 is provided on the side wall of the pre-positioning slider 844 close to the feed trough 842; the output end of the pre-positioning cylinder 843 is connected to the pre-positioning slider 844, and the pre-positioning cylinder 843 can drive the pre-positioning slider 844 to slide on the pre-positioning fixing seat 841, thereby driving the pre-positioning groove 845 to be connected or misaligned with the feed trough 842. In the initial state, the pre-positioning slot 845 is connected to the feeding slot 842; the second straight vibrator 82 works to send the shell into the feeding slot 842 until the shell behind sends the shell in front into the pre-positioning slot 845; then the pre-positioning cylinder 843 drives the pre-positioning slide 844 to slide, thereby driving the pre-positioning slot 845 and the shell to move together until the pre-positioning slot 845 is misaligned with the feeding slot 842; at this time, the pre-positioning fixed seat 841 seals the end of the pre-positioning slot 845 close to the feeding slot 842, thereby making the pre-positioning slot 845 a closed structure, limiting the shell fixing seat, so as to facilitate the shell picking robot 83 to grab the shell from the pre-positioning slot 845, thereby improving the stability of the processing. After the shell picking robot 83 completes grabbing the shell in the pre-positioning slot 845, the pre-positioning cylinder 843 resets and drives the pre-positioning slide 844 to reset until the pre-positioning slot 845 is connected to the feeding slot 842 again, so as to achieve continuous loading.

[0056] In this embodiment, there are four shell feeding slots 821, four feeding slots 842 and four pre-positioning slots 845, and the three are arranged in a one-to-one correspondence. By setting four pre-positioning slots 845, the shell loading mechanism 8 can simultaneously realize the loading of four shells, thereby improving processing efficiency.

[0057] like Figure 13 As shown, a material shortage sensor 822 is installed on the second straight vibrator 82. The material shortage sensor 822 is arranged at one end of the second straight vibrator 82 close to the second vibrating plate 81. The material shortage sensor 822 is connected to the controller 2 and is used to detect whether there is a shell on the second straight vibrator 82. The material shortage sensor 822 can detect whether there is a shell on the second straight vibrator 82. When the material shortage sensor 822 detects that there is no shell on the second straight vibrator 82, it will feedback a signal to the controller 2, indicating that there is a shortage of material on the second vibrating plate 81, so as to remind the operator to replenish the material in the second vibrating plate 81 in time.

[0058] In this embodiment, there are four material shortage sensors 822, each of which is disposed directly above each shell feeding slot 821, and can detect whether there is a shell in the corresponding shell feeding slot 821. In other embodiments, the number of material shortage sensors 822 can also be any other number.

[0059] like Figure 15 As shown, the shell picking robot 83 includes a third fixed seat 831, the third fixed seat 831 is slidably limitedly connected to the machine base 1, the third fixed seat 831 is connected to the cam drive device 3, the cam drive device 3 can drive the third fixed seat 831 to move up and down, the third fixed seat 831 is provided with a third picking cylinder 832, the output end of the third picking cylinder 832 is provided with a third picking mounting seat 833, the third picking mounting seat 833 is provided with a picking claw cylinder 834, the third picking cylinder 832 can drive the picking claw cylinder 834 to move back and forth between the pre-positioning component 84 and the product fixture 5. During processing, after the pre-positioning groove 845 limits the shell, the third material picking mounting seat 833 is driven by the third material picking cylinder 832 to move toward the pre-positioning fixed seat 841 until the third material picking mounting seat 833 moves to the top of the pre-positioning slider 844; the cam driving device 3 then drives the third fixed seat 831 and the third material picking mounting seat 833 to descend until the material picking claw cylinder 834 on the third material picking mounting seat 833 is connected with the shell on the pre-positioning groove 845, and the shell is clamped by the material picking claw cylinder 834; then The cam drive device 3 drives the third fixed seat 831 and the third material picking mounting seat 833 to rise, so that the material picking claw cylinder 834 grabs the shell; then the third material picking mounting seat 833 is driven by the third material picking cylinder 832 to move toward the direction close to the product fixture 5, until the third material picking mounting seat 833 drives the material picking claw cylinder 834 and the shell to move directly above the product fixture 5, and then the cam drive device 3 and the material picking claw cylinder 834 cooperate to place the shell on the product fixture 5 on the rotating material transport mechanism 4, completing the shell loading work.

[0060] To limit and guide the movement direction of the third retrieving mounting seat 833, a third slide rail 835 is mounted on the third fixing seat 831. The third retrieving mounting seat 833 slides and engages with the third slide rail 835. When the third retrieving cylinder 832 is in operation, the third retrieving mounting seat 833 slides on the third slide rail 835. The cooperation between the third retrieving mounting seat 833 and the third slide rail 835 limits the movement direction of the third retrieving mounting seat 833, ensuring that the third retrieving mounting seat 833 can accurately drive the retrieving jaw cylinder 834 to the corresponding position of the pre-positioning fixing seat 841 or the product fixture 5, thereby improving the accuracy of the transmission.

[0061] There are four material picking claw cylinders 834, and the four material picking claw cylinders 834 are evenly spaced on the third material picking mounting seat 833. The four material picking claw cylinders 834 correspond one-to-one to the four pre-positioning grooves 845 on the pre-positioning fixing seat 841, so that the loading work of four shells can be completed at the same time, thereby improving processing efficiency.

[0062] like Figure 16 As shown, the pressing mechanism 9 includes a shell detection component 91 and a pressing component 92. The shell detection component 91 is slidably connected to the machine base 1, and the shell detection component 91 is connected to the cam drive device 3. The cam drive device 3 can drive the shell detection component 91 to move up and down. The shell detection component 91 is used to detect whether there is a shell on the product jig 5. During operation, the rotary conveying mechanism 4 can drive the product jig 5 with the inner plug, filter membrane and shell to the corresponding position of the shell detection component 91. The cam drive device 3 drives the shell detection component 91 to descend, so that the shell detection component 91 is connected with the shell on the product jig 5, thereby detecting whether there is a shell on the product jig 5, and thus judging whether the shell feeding mechanism 8 has successfully loaded the material. The detected structure is fed back to the controller 2, which improves the stability of the processing and ensures the yield rate of the antibacterial film assembly machine. If the shell detection component 91 detects that there is a shell on the current product fixture 5, it controls the pressing component 92 to work, press the shell on the product fixture 5 into the outer periphery of the inner plug, so that the filter membrane is limited and fixed in the shell through the inner plug, completing the assembly process of the antibacterial membrane component.

[0063] Specifically, the shell detection component 91 includes a shell detection fixing seat 911, which is connected to the cam driving device 3. A pressing detection head 912 is provided on the shell detection fixing seat 911. The pressing detection head 912 is arranged one-to-one corresponding to the product fixture 5. The pressing detection head 912 is slidably limitedly connected to the shell detection fixing seat 911. The cam driving device 3 can drive the shell detection fixing seat 911 to move up and down, thereby driving the pressing detection head 912 to move towards or away from the product fixture 5. A proximity sensor 913 is provided at the corresponding position of the shell detection fixing seat 911 to the pressing detection head 912. The proximity sensor 913 is connected to the controller 2. The proximity sensor 913 is used to detect the position of the pressing detection head 912.

[0064] During specific operation, after the rotating material conveying mechanism 4 transports the product jig 5 with the shell placed thereon to the corresponding position of the shell detection component 91, the shell detection fixing seat 911 will be driven down by the cam driving device 3, driving the pressing detection head 912 to descend, and the pressing detection head 912 will be connected with the shell on the product jig 5; the reverse push of the shell will push the pressing detection head 912 to rise on the shell detection fixing seat 911. When the cam driving device 3 is driven to the extreme position, the shell on the product jig 5 will push the pressing detection head 912 to rise to the position corresponding to the proximity sensor 913. At this time, the proximity sensor 913 can detect the pressing detection head 912, which means that there is a shell on the product jig 5 corresponding to the pressing detection head 912. On the contrary, if there is no shell on the product fixture 5 corresponding to the pressing detection head 912, the pressing detection head 912 will not rise to the position corresponding to the proximity sensor 913. The proximity sensor 913 will not detect that the pressing detection head 912 cannot feedback a signal to the controller 2, and the controller 2 does not need to control the pressing component 92 to work.

[0065] The pressing assembly 92 includes a pressing fixing seat 921, which is fixedly connected to the machine base 1. A pressing cylinder 922 is provided at a position on the pressing fixing seat 921 corresponding to the pressing detection head 912. A pressing head 923 is provided on the output end of the pressing cylinder 922. The pressing cylinder 922 can drive the pressing head 923 to connect with the pressing detection head 912 and push the pressing detection head 912 to move toward the direction close to the product fixture 5. When the proximity sensor 913 detects that there is a shell on the current product fixture 5, it controls the pressing cylinder 922 to work, and the pressing cylinder 922 drives the pressure head 923 to descend, and the pressure head 923 will connect with the end of the pressing detection head 912 away from the product fixture 5; as the pressing cylinder 922 continues to drive, the pressure head 923 will push the pressing detection head 912 downward, and the pressing detection head 912 pushes the shell, pressing the shell onto the inner plug shell; when the pressing cylinder 922 is driven to the limit position, The outer shell is just fitted over the outer periphery of the inner plug, limiting and fixing the filter membrane in the outer shell, thus completing the assembly of the antibacterial membrane assembly; then the pressing cylinder 922 is reset, driving the pressure head 923 to rise to the initial position; then the cam drive device 3 will drive the outer shell detection fixing seat 911 to drive the pressing detection head 912 to rise, until the pressing detection head 912 leaves the product fixture 5 and resets to the initial position; then the rotating material transport mechanism 4 drives the product fixture 5 to move the pressed antibacterial membrane assembly to the next workstation.

[0066] like Figure 4 As shown, the product fixture 5 comprises a first fixture 51 and a second fixture 52, each fixedly mounted on the turntable 41. The inner plug loading mechanism 6, inner plug detection mechanism 15, filter membrane loading mechanism 7, outer shell loading mechanism 8, and pressing mechanism 9 are each connected to the first fixture 51. In other words, during assembly of the bacterial barrier membrane assembly, all components are placed on the first fixture 51. In this embodiment, the first fixture 51 is a solid structure, facilitating the pressing mechanism 9 to press-fit the outer shell and inner plug together. The second fixture 52 is a hollow tubular structure, facilitating subsequent processing and testing.

[0067] The product inspection mechanism includes a displacement component 16, a blowing component 17 and a visual inspection component 18 which are arranged in sequence along the rotation direction of the turntable 41. The displacement component 16 is respectively connected to the first clamp 51 and the second clamp 52, and is used to grab the product on the first clamp 51 and move it to the second clamp 52. The blowing component 17 is connected to the second clamp 52 and is used to blow air to the second clamp 52. The visual inspection component 18 is connected to the second clamp 52 and is used to detect whether the product on the second clamp 52 has a filter membrane.

[0068] During processing, the rotating material transport mechanism 4 can transport the first clamp 51 containing the product to the corresponding position of the displacement component 16, and by controlling the operation of the displacement component 16, the product on the first clamp 51 can be grabbed onto the second clamp 52; then the rotating material transport mechanism 4 drives the turntable 41 to rotate, and the second clamp 52 containing the product is transported to the corresponding position of the blowing component 17, and the blowing is performed by the blowing component 17; if there is no inner plug on the product in the current second clamp 52, the blowing of the blowing component 17 will blow away the filter membrane in the outer shell; then the rotating material transport mechanism 4 drives the turntable 41 to rotate, and the turntable 41 will drive the product to the corresponding position of the visual inspection component 18, and the visual inspection component 18 takes a picture of the product on the second clamp 52, so as to determine whether the product on the current second clamp 52 has a filter membrane, and feeds back the information to the controller 2, so that the unloading mechanism 10 can distinguish between good and defective products to meet the function of product sorting.

[0069] The visual inspection assembly 18 includes a camera mount 181 fixedly mounted on the base 1. A visual camera 182 is mounted on the camera mount 181 and is electrically connected to the controller 2. The turntable 41 transport mechanism transports the second fixture 52 containing the product to the imaging position of the visual camera 182. The visual camera 182 then captures an image of the product in the second fixture 52, allowing the controller 2 to determine whether the product in the second fixture 52 has a filter membrane.

[0070] like Figure 17As shown, specifically, the displacement assembly 16 includes a displacement fixing frame 161, which is connected to the cam driving device 3, and the cam driving device 3 can drive the displacement fixing frame 161 to move up and down. The displacement fixing frame 161 is provided with a displacement slider 162 and a displacement cylinder 163. The displacement slider 162 is slidably engaged with the displacement fixing frame 161, and the output end of the displacement cylinder 163 is connected to the displacement slider 162. The displacement slider 162 is provided with a displacement clamping cylinder 164, and the displacement cylinder 163 can drive the displacement clamping cylinder 164 to move back and forth between the first clamp 51 and the second clamp 52. During processing, after the turntable 41 transports the first fixture 51 with the product placed on it to the corresponding position of the displacement assembly 16, the cam drive device 3 drives the displacement fixing frame 161 to descend, so that the displacement clamping cylinder 164 descends to connect with the product on the first fixture 51; the product on the first fixture 51 is clamped by the displacement clamping cylinder 164, and then the cam drive device 3 drives the displacement fixing frame 161 to rise, so that the displacement clamping cylinder 164 grabs the product on the first fixture 51; then the displacement slider 162 is driven by the displacement cylinder 163 to drive the displacement clamping cylinder 164 to move toward the second fixture 52, until the displacement clamping cylinder 164 moves to directly above the second fixture 52, and then the cam drive device 3 and the displacement clamping cylinder 164 cooperate to place the product on the second fixture 52, thereby grabbing the product on the first fixture 51 to the second fixture 52.

[0071] like Figure 18 As shown, the blowing assembly 17 includes a blowing fixed seat 171, which is fixedly connected to the machine base 1. A blowing lifting cylinder 172 is provided on the blowing fixed seat 171, and a blowing mounting block 173 is provided on the output end of the blowing lifting cylinder 172. A blowing connector 174 is provided on the blowing mounting block 173, and the blowing connector 174 is connected to an external air source. When the rotary conveying mechanism 4 drives the second fixture 52 containing the product to the corresponding position of the blowing assembly 17, the blowing connector 174 is located directly above the second fixture 52. The blowing mounting block 173 is driven by the blowing lifting cylinder 172 to drive the blowing connector 174 downward, so that the blowing connector 174 is lowered to connect with the second fixture 52. The blowing connector 174 is blown out of the blowing connector 174 through the external air source on the blowing connector 174. If the product in the second fixture 52 at this time has an outer shell and a filter membrane but no inner plug, the high-pressure gas blown out by the blowing connector 174 will blow away the filter membrane in the outer shell. By setting up the blowing assembly 17 to blow away the filter membrane in the product without an inner plug, the subsequent visual inspection assembly 18 is facilitated to work, so that the visual inspection assembly 18 can accurately determine whether the product is good or defective.

[0072] like Figure 3 、 Figure 4As shown, the unloading mechanism 10 can remove the good and defective products from the second clamp 52 separately and collect them by classification, thereby completing the unloading and sorting function. The unloading mechanism 10 includes a unloading robot, a good product collection box 101, and a defective product collection box 102. The good product collection box 101 and the defective product collection box 102 are respectively detachably connected to the base 1, so as to facilitate the replacement of the good product collection box 101 or the defective product collection box 102.

The discharge end is connected, and the discharge cylinder 104 can drive the discharge mounting base 106 to slide on the discharge slide rail 105. The discharge mounting base 106 is provided with a first discharge clamping cylinder 107 and a second discharge clamping cylinder 108. The first discharge clamping cylinder 107 is used to grab the product from the second clamp 52 and place it in the good product collection box 101, and the second discharge clamping cylinder 108 is used to grab the product from the second clamp 52 and place it in the defective product collection box 102. The discharge cylinder 104 can drive the first discharge clamping cylinder 107 to connect to the second clamp 52 and the good product collection box 101 respectively. It should be noted that when the first unloading clamp cylinder 107 is connected to the second clamp 52, the second unloading clamp cylinder 108 is also connected to another adjacent second clamp 52; when the first unloading clamp cylinder 107 is connected to the good product collection box 101, the second unloading clamp cylinder 108 is also connected to the defective product collection box 102.

[0074] During specific operation, the rotary conveying mechanism 4 will transport the second clamp 52 containing good products or defective products to the corresponding position of the unloading mechanism 10 respectively. Then the unloading cylinder 104 is controlled to work, driving the unloading mounting seat 106 to slide on the unloading slide rail 105 until the first unloading clamping cylinder 107 moves to the top of the second clamp 52 containing good products, and the second unloading clamping cylinder 108 moves to the top of the second clamp 52 containing defective products. The unloading fixed seat 103 is driven to descend by the cam driving device 3, driving the first unloading clamping cylinder 107 and the second unloading clamping cylinder 108 to descend to connect with the products on the second clamp 52. The first unloading clamping cylinder 107 is used to unload the product. The good products on the second clamp 52 are grabbed, and the defective products on the second clamp 52 are grabbed by the second unloading clamp cylinder 108. Then, through the cooperation of the cam drive device 3 and the unloading cylinder 104, the first unloading clamp cylinder 107 moves to the good product collection box 101, and the good products are placed on the good product collection box 101, completing the unloading and collection of good products; at the same time, the second unloading clamp cylinder 108 will also move to the defective product collection box 102, and place the defective products into the defective product collection box 102, completing the unloading and collection of defective products.
