[0029] like Figure 1-7 As shown, a filter membrane cutting and feeding mechanism for a bacterial barrier film assembly machine includes a machine base and a controller. The machine base is provided with a transport mechanism and a cam drive device respectively connected to the controller. The transport mechanism is provided with a product jig. The product jig is used to place the products to be assembled, and the transport mechanism can transport the product jig containing the products to the corresponding position of the filter membrane cutting and feeding mechanism. The filter membrane cutting and feeding mechanism is used to cut the roll filter membrane into preset sizes and place it on the product jig on the transport mechanism. The transport mechanism can transport the product jig with the filter membrane to the next workstation.

[0030] The filter membrane cutting and feeding mechanism includes a filter membrane cutting component 1, a filter membrane splicing component 2 and a filter membrane picking robot 3 respectively connected to the controller. The filter membrane cutting component 1 is connected to the machine base and is used to cut the entire roll of filter membrane into a preset size. The filter membrane splicing component 2 is connected to the filter membrane cutting component 1 and is used to receive the filter membrane cut by the filter membrane cutting component 1 and transport the filter membrane to the corresponding position of the filter membrane picking robot 3. The filter membrane picking robot 3 is connected to the cam driving device. The filter membrane picking robot 3 is used to suck the filter membrane on the filter membrane splicing component 2 and place the filter membrane on the product jig. Before processing, the whole roll of filter membrane can be placed on the filter membrane cutting component 1; during processing, the product jig on which the product to be processed is placed is transported to the corresponding position of the filter membrane picking manipulator 3 by the material transport mechanism, and then the filter membrane cutting component 1 is controlled to cut the whole roll of filter membrane into a preset size, and the cut filter membrane will automatically fall onto the filter membrane receiving component 2; the filter membrane receiving component 2 is used to transport the cut filter membrane to the corresponding position of the filter membrane picking manipulator 3, and then the filter membrane picking manipulator 3 sucks the filter membrane on the filter membrane receiving component 2 and places the filter membrane on the product jig, thereby completing the cutting and feeding process of the filter membrane. The filter membrane cutting and feeding mechanism can automatically feed the cut filter membrane to the product jig through the cooperation of the filter membrane picking component 2 and the filter membrane picking manipulator 3, so that it can meet the processing requirements of automated assembly, improve the degree of automation of the antibacterial membrane assembly machine, and improve the assembly efficiency of the antibacterial membrane.

[0031] like Figure 2 As shown, the filter membrane cutting assembly 1 includes a cutting fixed seat 11, which is fixedly mounted on the machine base. The cutting fixed seat 11 is provided with a film pulling mechanism and a punching mechanism 4. The film pulling mechanism is provided with a feed roller 12. The feed roller 12 is used to place the roll filter membrane to be punched. The roll filter membrane can be stretched and laid on the punching mechanism 4 and the film pulling mechanism. The film pulling mechanism is used to pull the roll filter membrane. The punching mechanism 4 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 12 and stretched and laid on the punching mechanism 4 and the film pulling mechanism in turn; by controlling the operation of the punching mechanism 4, 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 4, so that the punching mechanism 4 can achieve continuous punching. The filter membrane cutting and feeding mechanism can automatically and continuously cut the roll filter membrane through the cooperation of the film pulling mechanism and the punching mechanism 4 without manual intervention, thereby improving the automation level of the equipment, reducing labor costs, and improving processing efficiency.

[0032] like Figure 4 、 Figure 5As shown, the punching mechanism 4 includes a punching fixture 41, which is fixedly mounted on the cutting fixture 11. A punching cylinder 42 is fixedly mounted on the punching fixture 41. Four punching needles 43 are mounted on the output end of the punching cylinder 42. Punching holes 44 are respectively provided on the punching fixture 41 at positions corresponding to the punching needles 43. Through the cooperation of the four punching needles 43 and the punching holes 44, the punching mechanism 4 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 44. The punching cylinder 42 can drive the punching needles 43 to extend into or out of the punching hole 44. The filter membrane material receiving assembly 2 is arranged below the punching hole 44. During specific operation, after the roll filter membrane is placed on the feeding roller 12, one end of the roll filter membrane will be pulled and laid on the punching fixing seat 41 and the membrane pulling mechanism in turn, so that the roll filter membrane covers each punching hole 44 respectively; during punching, the punching cylinder 42 is controlled to work, and the punching needle 43 is driven to descend, so that the punching needle 43 is connected with the roll filter membrane and squeezes the roll filter membrane; as the punching needle 43 descends, it will extend into the punching hole 44, and the punching needle 43 cuts the roll filter membrane into a size that matches the end face of the punching needle 43, and enters the punching hole 44 with the cut filter membrane. After the cut filter membrane enters the punching hole 44, it will fall onto the filter membrane receiving assembly 2 due to its own gravity; then the punching cylinder 42 is controlled to reset, and the punching needle 43 is driven to rise and extend out of the punching hole 44 to reset to its initial position.

[0033] In order to limit and guide the lifting and lowering movement direction of the punching needle 43, two punching guide rods 45 are installed on the punching fixed seat 41. A punching needle mounting seat 46 is provided on the output end of the punching cylinder 42. The punching needle 43 is fixedly mounted on the punching needle mounting seat 46. The punching guide rods 45 pass through the punching needle mounting seat 46 and are slidably connected to the punching needle mounting seat 46. When the punching cylinder 42 is working, it drives the punching needle mounting seat 46 and the punching needle 43 to move, and the punching needle mounting seat 46 slides on the punching guide rods 45. The cooperation between the punching needle mounting seat 46 and the punching guide rods 45 can limit and guide the movement direction of the punching needle 43, thereby ensuring that the punching needle 43 can be lifted and lowered in a straight line, so that it can smoothly extend into the punching hole 44 and complete the punching of the filter membrane. This can not only improve the punching efficiency, but also prevent the punching needle 43 from colliding and breaking, thereby improving the processing stability.

[0034] In order to avoid the upward deformation of the rolled filter membrane during punching, a punching and pressing block 47 is provided on the punching and pressing fixed seat 41. The punching and pressing block 47 is placed on the punching and pressing fixed seat 41 and movably cooperates with the punching and pressing fixed seat 41. A needle hole 48 is provided at the corresponding position of the punching and pressing block 47 and the punching hole 44. A pressing guide rod 49 is provided on the punching and pressing block 47. The pressing guide rod 49 passes through the punch needle mounting seat 46 and cooperates with the punch needle mounting seat 46 for sliding limit. The punching cylinder 42 can drive the punch needle 43 to pass through the needle hole 48. During processing, the rolled filter membrane is stretched and laid through the gap between the punching fixing seat 41 and the punching pressing block 47, and the punching pressing block 47 will press and cover the rolled filter membrane; during the punching process, the punching cylinder 42 works to drive the punch needle 43 to descend, and the punch needle 43 will slide in the needle hole 48, and the punch needle mounting seat 46 slides on the pressing guide rod 49, and the rolled filter membrane is pressed by the punching pressing block 47, which can prevent the rolled filter membrane from curling up and deforming, ensure that the punch needle 43 can smoothly cut the filter membrane, and improve the stability of the processing; moreover, by arranging a needle hole 48 on the punching pressing block 47 to cooperate with the punch needle 43, the movement direction of the punch needle 43 can also be limited, further improving the stability of the processing.

[0035] like Figure 2 As shown, the film-drawing mechanism includes a film-drawing mounting frame 13, which is slidably connected to the cutting fixed seat 11. A drawing roller 14 and a recovery roller 15 are installed on the film-drawing mounting frame 13. The feed roller 12, the drawing roller 14, and the recovery roller 15 are respectively rotatably connected to the film-drawing mounting frame 13. The drawing roller 14 is used to pull the roll filter membrane to move on the film-drawing mounting frame 13, and the recovery roller 15 is used to rewind the waste roll filter membrane after cutting. The roll filter membrane on the feed roller 12 can be laid on the drawing roller 14 and the recovery roller 15 in sequence. The film-drawing mounting frame 13 is provided with a film-drawing drive assembly, which is respectively connected to the drawing roller 14 and the recovery roller 15 to drive the drawing roller 14 and the recovery roller 15 to rotate on the film-drawing mounting frame 13. Before processing, the roll filter membrane is first hung on the feed roller 12; then one end of the roll filter membrane is pulled to pass through the gap between the punching fixing seat 41 and the punching pressing block 47, and then stretched and laid on the drawing roller 14 and the recovery roller 15 respectively; during processing, when the punching mechanism 4 has punched the roll filter membrane, the film pulling drive assembly is controlled to work, and the drawing roller 14 and the recovery roller 15 are driven to rotate respectively. The drawing roller 14 will pull the roll filter membrane on the feed roller 12 toward the drawing roller 14, so that the new roll filter membrane is laid on the punching hole 44, and the recovery roller 15 can rotate to reel up the waste roll filter membrane after punching.

[0036] like Figure 2 、 Figure 3As shown, in this embodiment, the film-drawing drive assembly includes a film-drawing motor 16, which is fixedly mounted on a film-drawing mounting frame 13. A film-drawing active wheel 17 is mounted on the output end of the film-drawing motor 16, a film-drawing driven wheel 18 is mounted on one end of the material-drawing roller 14, and a recovery driven wheel 19 is mounted on one end of the recovery roller 15. A film-drawing transmission belt 110 is sleeved on the film-drawing active wheel 17 and the film-drawing driven wheel 18, and a recovery transmission belt 111 is sleeved on the recovery driven wheel 19 and the film-drawing driven wheel 18. By providing the film-drawing transmission belt 110 and the recovery transmission belt 111, the film-drawing motor 16 can simultaneously drive the material-drawing roller 14 and the recovery roller 15 to rotate synchronously, thereby achieving the functions of drawing the roll filter membrane and recovering the waste of the roll filter membrane. In other embodiments, other structural devices for realizing rotational drive can also be used, such as motor gear structures, etc.

[0037] A pressing roller 112 and a plurality of tensioning rollers 113 are mounted on the film-drawing mounting frame 13. The pressing roller 112 is connected to the film-drawing mounting frame 13 in an adjustable limit position and can rotate on the film-drawing mounting frame 13. By adjusting the pressing roller 112, the pressing roller 112 can be connected to or separated from the material-drawing roller 14. Before processing, the pressing roller 112 is first adjusted to separate from the material-drawing roller 14, thereby facilitating the laying of the roll filter membrane onto the material-drawing roller 14. After the roll filter membrane is laid onto the material-drawing roller 14, the pressing roller 112 is adjusted to move toward the material-drawing roller 14 until the pressing roller 112 contacts the other end face of the roll filter membrane. This allows the roll filter membrane to move when the film-drawing motor 16 is operating and the material-drawing roller 14 rotates. The tensioning rollers 113 are rotatably connected to the film-pulling mounting frame 13. Before processing, the roll filter membrane is laid on each tensioning roller 113 respectively. The purpose of setting up multiple tensioning rollers 113 is to enable the roll filter membrane to be tensioned on the film-pulling mounting frame 13, thereby increasing the tension of the roll filter membrane; ensuring that the punching mechanism 4 can smoothly cut the roll filter membrane, thereby improving the stability of processing.

[0038] like Figure 3 As shown, a transverse drive assembly 5 is provided on the cutting fixed seat 11. The transverse drive assembly 5 is used to drive the film pulling mounting frame 13 to move laterally on the cutting fixed seat 11, thereby driving the roll filter membrane to move laterally on the punching fixed seat 41. Because the width of the roll filter membrane is much larger than the sum of the diameters of the four filter membranes punched out by the punching needle 43, the transverse drive assembly 5 is provided to drive the roll filter membrane to move laterally, so that the roll filter membrane that has not been punched can be aligned with the punching hole 44, thereby improving the material utilization rate of the roll filter membrane, reducing the generation of waste materials, and saving costs. In the actual operation process, the transverse drive assembly 5 is controlled to work once, and the punching mechanism 4 is controlled to punch once; after the utilization rate of the roll filter membrane is maximized, the film pulling motor 16 is controlled to drive the pulling roller 14 to pull the roll filter membrane to move. According to the different widths of the roll filter membrane, the number of times the transverse drive assembly 5 works can be adaptively adjusted.

[0039] In this embodiment, the transverse drive assembly 5 includes a transverse motor 51, which is connected to the cutting fixture 11. A transverse screw 52 is provided at the output end of the transverse motor 51. A transverse slider 53 is sleeved on the transverse screw 52, ​​and the transverse slider 53 is connected to the film-drawing mounting frame 13. During operation, the transverse motor 51 drives the transverse screw 52 to rotate, thereby driving the transverse slider 53 to slide on the transverse screw 52. The transverse slider 53 drives the film-drawing mounting frame 13 to move synchronously, allowing the roll filter membrane to move laterally on the punching fixture 41, thereby aligning the uncut roll filter membrane with the punching hole 44.

[0040] To limit and guide the movement direction of the film-drawing mounting frame 13, a transverse guide block 54 is provided on the film-drawing mounting frame 13, and a transverse guide rail 55 is provided on the cutting fixture 11. The transverse guide block 54 and the transverse guide rail 55 are slidably engaged. The cooperation between the transverse guide block 54 and the transverse guide rail 55 limits and guides the movement direction of the film-drawing mounting frame 13, ensuring that the roll filter membrane can move laterally on the punching fixture 41, thereby improving transmission accuracy and processing stability.

[0041] like Figure 1 、 Figure 2 、 Figure 6 As shown, the filter membrane material receiving assembly 2 includes a material receiving fixed plate 21, which is fixedly connected to the cutting fixed seat 11. The material receiving fixed plate 21 is provided with a material receiving transverse movement cylinder 22 and a material receiving guide rail 23. A material receiving mounting block 24 is slidably provided on the material receiving guide rail 23. A material receiving lifting cylinder 25 is provided on the material receiving mounting block 24. A material receiving block 26 is provided on the output end of the material receiving lifting cylinder 25. The material receiving mounting block 24 is connected to the output end of the material receiving transverse movement cylinder 22. A material receiving trough 27 is provided on the material receiving block 26 at a position corresponding to the punching hole 44. The material receiving trough 27 is externally connected to a negative pressure device. The material receiving transverse movement cylinder 22 can drive the material receiving block 26 to connect to the punching fixed seat 41 or the filter membrane material taking manipulator 3 respectively. The material receiving lifting cylinder 25 can drive the material receiving block 26 to move up and down, thereby driving the material receiving trough 27 to connect or separate with the punching hole 44.

[0042] In the initial state, the receiving transverse cylinder 22 is retracted, and the receiving block 26 is located directly below the punching fixed seat 41; the receiving lifting cylinder 25 is extended, so that the receiving trough 27 is connected to the punching hole 44 and is located directly below the punching hole 44. During processing, when the punching mechanism 4 completes punching of the filter membrane, the punched filter membrane will fall through the punching hole 44 into each receiving trough 27; the negative pressure device externally connected to the receiving trough 27 allows the receiving trough 27 to absorb the filter membrane. After that, the material receiving lifting cylinder 25 is controlled to retract, so that the material receiving trough 27 is separated from the punching hole 44; then the material receiving transverse displacement cylinder 22 is controlled to extend, driving the material receiving mounting block 24 to slide on the material receiving guide rail 23, and the material receiving mounting block 24 drives the material receiving lifting cylinder 25, the material receiving block 26 and the filter membrane to move together until the material receiving block 26 moves to the feeding position of the filter membrane picking robot 3; then the filter membrane picking robot 3 sucks the filter membrane from the material receiving trough 27 and guides the filter membrane to the product fixture, completing the filter membrane feeding process. After the filter membrane picking robot 3 sucks the filter membrane from the material receiving trough 27, the material receiving transverse displacement cylinder 22 is controlled to retract and reset, driving the material receiving block 26 to move to the initial position; then the material receiving lifting cylinder 25 is controlled to extend, driving the material receiving block 26 to rise until the material receiving trough 27 is connected to the punching hole 44, so as to facilitate the next round of filter membrane punching processing.

[0043] In this embodiment, the receiving block 26 is provided with four receiving slots 27, each of which is externally connected to a negative pressure device, and the receiving slots 27 are arranged in a one-to-one correspondence with the punching holes 44. In other embodiments, the number of receiving slots 27 can also be adjusted according to the number of punching holes 44 and punching needles 43.

[0044] To limit the movement of the material receiving mounting block 24, two material receiving buffers 28 are installed on the material receiving fixing plate 21. The material receiving mounting block 24 can abut against the two material receiving buffers 28 respectively. In the initial state, the material receiving mounting block 24 abuts against one of the material receiving buffers 28. At this time, the material receiving groove 27 on the material receiving block 26 is exactly aligned with the corresponding punching hole 44. When the material receiving transverse movement cylinder 22 is in operation, it drives the material receiving mounting block 24 to slide on the material receiving guide rail 23 until the material receiving mounting block 24 abuts against the other material receiving buffer 28. At this time, the material receiving mounting block 24 drives the material receiving block 26 to the loading position of the filter membrane retrieving robot 3. By providing two material receiving buffers 28, the movement of the material receiving mounting block 24 can be limited, ensuring that the material receiving mounting block 24 can drive the material receiving block 26 to move accurately to the corresponding position of the punching hole 44 or the loading position of the filter membrane retrieving robot 3.
