Description

Technical Field

[0001] This utility model relates to the field of nuclear pore membrane technology, and in particular to an irradiation and feeding system for nuclear pore membranes. Background Technology

[0002] Nuclear pore membranes are extremely precise microporous filtration membranes. They are porous plastic films with numerous tiny pores distributed across them, each pore being identical in shape and size. Nuclear pore membranes come in various specifications, with thicknesses ranging from 6 micrometers to 150 micrometers and pore sizes ranging from 0.02 micrometers to 15 micrometers.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0052] Before providing a further detailed description of the embodiments of this utility model, the directional terms used in the embodiments of this utility model, such as "upper part", "lower part" and "side part", do not have the meaning of limiting the scope of protection of this utility model.

[0053] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0054] like Figures 1 to 6 As shown, one embodiment of this utility model provides an irradiation and feeding system for nuclear pore membranes, including: an irradiation mechanism 210; an unwinding assembly 220 and a winding assembly 230, the unwinding assembly 220 and the winding assembly 230 being arranged symmetrically above and below the irradiation mechanism 210; and a first automatic loading and unloading module 240, disposed on the side of the unwinding assembly 220 opposite to the irradiation mechanism 210, the first automatic loading and unloading module 240 being configured to place the raw material membrane roll onto the unwinding assembly 220 and to load the tail end of the membrane roll onto the unwinding assembly 220. The film roll is removed from the unwinding assembly 220; the second automatic loading and unloading module 250 is located on the side of the winding assembly 230 away from the irradiation mechanism 210. The second automatic loading and unloading module 250 is configured to remove the finished film roll from the winding assembly 230 and place the empty core onto the winding assembly 230; wherein, the unwinding assembly 220 and the winding assembly 230 are driven by drive motors respectively to realize the synchronous unwinding and winding of the nuclear pore membrane, and the nuclear pore membrane can be changed without stopping the machine.

[0055] Among them, such as Figure 1 and Figure 2As shown, the irradiation and loading system for the nuclear pore membrane in this embodiment includes an irradiation mechanism 210, an unwinding assembly 220, a winding assembly 230, a first automatic loading / unloading module 240, and a second automatic loading / unloading module 250. The unwinding assembly 220 and the winding assembly 230 are disposed on both sides of the irradiation mechanism 210 in the width direction, that is, the unwinding assembly 220 and the winding assembly 230 are arranged in a vertically symmetrical structure relative to the irradiation mechanism 210. The unwinding assembly 220 and the winding assembly 230 are driven by drive motors respectively to realize the synchronous unwinding and winding of the nuclear pore membrane, thereby improving the reliability of winding and unwinding. The first automatic loading / unloading module 240 is disposed on the side of the unwinding assembly 220 away from the irradiation mechanism 210, and the second automatic loading / unloading module 250 is disposed on the side of the winding assembly 230 away from the irradiation mechanism 210. Based on this, during use, the raw material film roll can be placed in the unwinding assembly 220, and the free end of the core membrane on the raw material film roll is connected to the empty core of the winding assembly 230. The core membrane can be irradiated by the irradiation mechanism 210. With the setting of the first automatic loading and unloading module 240 and the second automatic loading and unloading module 250, the unwinding assembly 220 can be loaded (raw material film roll) and unloaded (tail film roll), and the winding assembly 230 can be loaded (empty core) and unloaded (finished film roll), replacing the forklift loading in the traditional technology, making loading more convenient, and the automated control makes loading and unloading more accurate, improving work efficiency and reducing labor intensity.

[0056] It should be noted that the unwinding assembly 220 and the winding assembly 230 are driven by drive motors to achieve synchronous unwinding and winding of the nuclear pore membrane.

[0057] like Figure 3 As shown, in one feasible implementation, the irradiation and feeding system further includes:

[0058] An auxiliary feeding device 100 is disposed on the periphery of the unwinding assembly 220 or the winding assembly 230. The auxiliary feeding device 100 is used to assist in loading and unloading when the first automatic loading and unloading module 240 or the second automatic loading and unloading module 250 malfunctions.

[0059] Furthermore, by providing the auxiliary feeding device 100, when the first automatic loading / unloading module 240 and / or the second automatic loading / unloading module 250 malfunction, the auxiliary feeding device 100 can be used for feeding, enabling continuous operation of the nuclear pore membrane irradiation and feeding system. This ensures overall work efficiency, reduces production downtime due to malfunctions, and improves the irradiation efficiency of the nuclear pore membrane.

[0060] In one feasible implementation, the first automatic loading and unloading module 240 and the second automatic loading and unloading module 250 have the same structure, both including a loading component 311. The loading component 311 includes a film roll conveying device 3111, a film roll fixing device 3112, and a pusher slide rail 3113. The film roll fixing device 3112 is located close to the unwinding component 220 or the winding component 230. The film roll fixing device 3112 includes slots, the number of which is the same as the number of film rolls required by the winding component 220 or the unwinding component 230. The film roll fixing device 3112 is mounted on the pusher slide rail 3113 and can move on the pusher slide rail 3113 and is aligned with the axis of the unwinding component 220 or the winding component 230.

[0061] The first automatic loading and unloading module 240 and the second automatic loading and unloading module 250 can have the same structure. This arrangement facilitates the production and processing of the first automatic loading and unloading module 240 and the second automatic loading and unloading module 250, and also facilitates the assembly and layout of the nuclear pore membrane irradiation and loading system.

[0062] In this technical solution, a first automatic loading and unloading module 240 and a second automatic loading and unloading module 250 are further provided. Both can include a loading component 311. The loading component 311 includes a film roll conveying device 3111, a film roll fixing device 3112 and a pusher slide rail 3113. The film roll fixing device 3112 includes at least two rows of slots, the same number as the unwinding unit and the rewinding unit. Based on this, during the operation, the film roll enters the slot area of ​​the film roll fixing device 3112 from the storage area through the film roll conveying device 3111. After the tray under each film roll enters the corresponding slot, it will stop and then push the film roll into the corresponding slot. When feeding, the overall film roll fixing device 3112, driven by a servo motor, moves towards the empty shaft area of ​​the unwinding assembly 220 or the take-up assembly 230 until the film roll is pushed onto the empty shaft of the unwinding assembly 220 and the take-up assembly 230. Feeding is then complete. Upon receiving a feedback signal, the first automatic loading / unloading module 240 and the second automatic loading / unloading module 240 retract (the unloading assembly 312 can be pushed forward), awaiting the next feeding. The film roll fixing device 3112 can be slidably connected to the pusher rail 3113, facilitating the movement of the fixing device 3112 to align with the empty shaft center (unwinding shaft and take-up shaft) of the unwinding assembly or the take-up assembly. This allows the pusher device on the film roll fixing device 3112 to push the raw material film roll onto the unwinding shaft 2211 of the unwinding assembly and the empty core onto the take-up shaft 2311 of the take-up assembly, thus achieving feeding. It is understandable that the retraction and advancement of the feeding component 311 and the advancement and retraction of the unloading component 312 can be achieved through the slide rail, which will not be elaborated further. The film roll can be moved from the storage area to the slot area of ​​the film roll fixing device 3112 through the film roll conveying device 3111, which can be achieved by the robot arm 3121 or by the pushing device (telescopic rod).

[0063] The film roll can be a finished film roll, a tailings film roll, an empty core, or a raw material film roll. During loading, the empty core is usually placed on the winding assembly 230, the raw material film roll is placed on the unwinding assembly 220, and the free end of the raw material film roll is manually wound onto the empty core of the winding assembly 230 through the irradiation port for irradiation.

[0064] It is understandable that, such as Figure 4 As shown, the material can also be picked up by the robot arm 3121 in the unloading component 312. After the raw material film roll is picked up by the robot arm 3121, it is pushed into the unwinding component 220 (unwinding shaft 2211). At the same time, the empty core is picked up by the robot arm 3121 on the other side and pushed into the winding component 230 (winding shaft 2311). Then the unwound film (nuclear pore film) is connected to the empty core on the winding side for irradiation. The winding component 230 and the unwinding component 220 are driven at the same time to realize the irradiation of the nuclear pore film. After the irradiation is completed, the finished film roll is located on the winding shaft 2311 of the winding component 220.

[0065] In one feasible implementation, the first automatic loading and unloading module 240 and the second automatic loading and unloading module 250 have the same structure and also include a loading component 312. The loading component 312 includes multiple robotic arms 3121, a finished product loading conveyor belt 3122 and an empty roll loading conveyor belt 3123. The multiple robotic arms 3121 are arranged close to the unwinding component 220 or the winding component 230. The multiple robotic arms 3121 are configured to grip the tail film roll on the unwinding component 220, or the multiple robotic arms 3121 are configured to grip the finished film roll on the winding component 230.

[0066] The system further provides the structural composition of a first automatic loading / unloading module 240 and a second automatic loading / unloading module 250. Each module can include multiple robotic arms 3121, a finished product unloading conveyor belt 3122, and an empty roll unloading conveyor unit 3123. During operation, the robotic arms 3121 can smoothly unload the irradiated finished membrane rolls from the take-up shaft 2311 and place them onto the finished product unloading conveyor belt 3122, transferring the irradiated nuclear porous membrane (finished membrane roll) to the finished product area. The robotic arms 3121 can also place empty rolls from the empty roll unloading conveyor belt 3123 onto the take-up shaft 2311. This enables precise loading and unloading of the porous membrane irradiation system. In other words, in addition to loading via the loading component 311, loading can also be performed via the robotic arms 3121, preventing a malfunction in one component from affecting the operation of the irradiation and loading system. Multiple loading methods improve the reliability of the irradiation and loading system. Similarly, on one side of the winding assembly 230, the raw material film roll on the finished product unloading conveyor belt 3122 can be installed on the unwinding shaft 2211 of the unwinding assembly 220 by the robot arm 3121, and the tail film roll on the unwinding shaft 2211 can be removed by the robot arm 3121 and placed in the empty roll unloading conveyor unit 3123.

[0067] like Figure 5 As shown, the finished film rolls on the film winding machine (winding assembly 230) are picked up by the robot arm 3121 and placed onto the conveyor line (finished product unloading conveyor belt 3122). At the same time, the tail film rolls on the film winding machine (unwinding assembly 220) are picked up by the robot arm 3121 and placed onto the conveyor line (empty roll unloading conveyor unit 3123). The finished film rolls and tail film rolls are then transported to different warehouses for transfer.

[0068] In one feasible implementation, the unwinding assembly 220 includes: a plurality of unwinding units 221, the plurality of unwinding units 221 being arranged in at least two rows, the plurality of unwinding units 221 being arranged along the length direction of the irradiation mechanism 210; wherein, each unwinding unit 221 includes at least two unwinding shafts 2211, and the raw material film roll or tail material film roll is disposed on the unwinding shaft 2211.

[0069] In this technical solution, the unwinding assembly 220 is further provided. The unwinding assembly 220 may include multiple unwinding units 221, which are arranged in at least two rows to improve unwinding efficiency. Each unwinding unit 221 includes at least two unwinding shafts 2211, which can be in a working and standby state to improve unwinding efficiency and realize continuous operation of the nuclear pore membrane irradiation and feeding system. That is, while the nuclear pore membrane on one unwinding shaft 2211 (rewinding shaft 2311) is being irradiated, the other unwinding shaft 2211 (rewinding shaft 2311) can be used for feeding. After feeding and irradiation are completed, the free end of the nuclear pore membrane is manually wound onto the empty roll of the rewinding shaft 2311, while the robotic arm 3121 performs the unwinding operation. This process is repeated to improve the irradiation efficiency of the nuclear pore membrane. Understandably, the film roll fixing device 3112 is equipped with a fixing channel, and matching receiving spaces can be provided on both sides of the fixing channel. The card slot can be moved between the two receiving spaces to enable feeding of the unwinding shaft 2211 and the two take-up shafts 2311 at two different positions. The card slot has an outer wall, and a slider is provided on the side of the outer wall away from the slot opening. The slider can be moved between the fixing channels to realize the change of the card slot position.

[0070] In one feasible implementation, the winding assembly 230 includes: a plurality of winding units 231, the plurality of winding units 231 being arranged in at least two rows, the plurality of winding units 231 being arranged along the length direction of the irradiation mechanism 210; wherein, each winding unit 231 includes at least two winding shafts 2311, and the finished film roll or empty core is disposed on the winding shaft 2311.

[0071] Similarly, this technical solution further provides the structural composition of the winding assembly 230. The winding assembly 230 may include multiple winding units 231, which are arranged in at least two rows to improve winding efficiency. Each winding unit 231 includes at least two winding shafts 2311, which can be in a standby state, further improving winding efficiency and enabling continuous operation of the pore membrane irradiation system. The two winding shafts 2311 are matched with two unwinding shafts 2211. When the first irradiation begins, the second is loaded; when the second irradiation begins, the first is unloaded and reloaded, and so on, thereby improving the irradiation efficiency of the nuclear pore membrane.

[0072] Specifically, the irradiation and feeding system for the nuclear pore membrane of this application adopts an upper and lower structure, with an unwinding assembly 220 on the upper layer and a winding assembly 230 on the lower layer. Alternatively, the upper layer could be the unwinding assembly 230 and the lower layer the winding assembly 220. The unwinding assembly 220 can be modularly configured in multiple groups; for example, in this embodiment, there are 42 unwinding units 221, divided into 6 groups of 7. The free ends of the nuclear pore membrane on the 7 unwinding units 221 in each group are wound onto the 7 winding units 231, and then combined together and irradiated through the accelerator beam port. As the nuclear pore membrane passes through the irradiation port, it is gradually wound up by the winding units 231, thus completing the irradiation of multiple raw material membrane rolls. It should be noted that a push-out device can also be installed on the unwinding shaft 2211 and the rewinding shaft 2311. When the robot arm 3212 malfunctions and cannot unload, the finished film roll and the tail film roll can be pushed off the shaft. A conveyor belt can be installed below the unwinding shaft 2211 and the rewinding shaft 2311 to transport the pushed-off finished film roll and tail film roll away, reducing manual intervention and improving work efficiency.

[0073] It is understood that the above-mentioned slide movement operation is implemented through a programming program in the control system, but the above-mentioned movement sequence needs to be provided to the programmer. The programming program is not a solution protected in this application, so it will not be described in detail here.

[0074] like Figure 3 As shown, in one feasible embodiment, the auxiliary feeding device 100 includes: a support 110; a movable member 120 slidably connected to the support 110; an air shaft 130 hinged to the movable member 120; and a first drive assembly configured to drive the movable member 120 to move the air shaft 130 on the support 110.

[0075] The auxiliary feeding device 100 provided in this application embodiment includes a bracket 110, a movable component 120, an air expansion shaft 130, and a first drive assembly. Based on this, when feeding the perforated membrane irradiation system using the auxiliary feeding device 100, the angle of the air expansion shaft 130 can be adjusted so that the air expansion shaft 130 is inserted into the membrane roll. Then, the air expansion shaft 130 is controlled to expand, thus tightening the membrane roll. After that, the first drive assembly is activated, driving the movable component 120 to move on the bracket 110. The movable component 120 will then drive the air expansion shaft 130 to move in conjunction with the membrane roll. When the movable component 120 has moved into position, the air expansion shaft 130 can be released, completing the feeding of the membrane roll. This makes membrane roll feeding more convenient, increases feeding accuracy, reduces manual intervention, and ensures operational safety.

[0076] It is understandable that the support 110 has a certain height. During use, the auxiliary feeding device 100 is arranged on one side of the pore membrane irradiation system. By controlling the movable part 120 to move along the height direction of the support 110, the air shaft 130 can be used to feed the pore membrane irradiation system.

[0077] In one possible implementation, the auxiliary feeding device 100 further includes a second drive assembly configured to drive the rotation of the air shaft 130 relative to the movable member 120.

[0078] In this technical solution, the auxiliary feeding device 100 may also include a second drive component. The second drive component facilitates the rotation of the air shaft 130 relative to the movable part 120, facilitates the adjustment of the angle of the air shaft 130, and facilitates the insertion of the air shaft 130 into the film roll, making feeding more convenient.

[0079] In one feasible implementation, the auxiliary feeding device 100 further includes: a slide rail, which is arranged along the height direction of the support 110, and the movable member 120 is slidably connected to the slide rail; and a base 140, to which the support 110 is connected.

[0080] In this technical solution, the auxiliary feeding device 100 may also include a slide rail, which facilitates the movement of the movable part 120 relative to the support 110.

[0081] Furthermore, the auxiliary feeding device 100 may also include a base 140 and casters 150. The base 140 provides an installation position for the bracket 110, and the casters 150 facilitate the movement of the auxiliary feeding device 100.

[0082] In this technical solution, the auxiliary feeding device 100 may also include a counterweight, which can reduce the probability of the auxiliary feeding device 100 tipping over.

[0083] In this technical solution, the auxiliary feeding device 100 may also include an electrical control box 160 and a control component. The electrical control box 160 is located on one side of the bracket 110 and can be connected to the base 140. The electrical control box 160 provides an installation position for the control component. The control component can control the tension and relaxation of the air shaft 130 and control the opening and closing of the first drive component. Based on this, the entire feeding process can be controlled.

[0084] Understandably, the control component can also be connected to the second drive component, thereby allowing the setting angle of the air shaft 130 to be adjusted via the second drive component.

[0085] like Figure 3 As shown, in one feasible implementation, the control component is also used to determine the tension strength of the air shaft 130 and the rotational speed of the first drive component based on the weight of the membrane roll.

[0086] In this technical solution, a specific control method for the control component is further provided. The control component can also be used to determine the tension strength of the air shaft 130 and the rotation speed of the first drive component based on the weight of the film roll. Based on this, the tension strength of the air shaft 130 and the rotation speed of the first drive component can be related to the weight of the film roll, which can make the feeding of the film roll safer.

[0087] In one feasible implementation, the auxiliary feeding device 100 further includes a pusher, which is arranged on the top of the support 110 or connected to the movable member 120, and is used to push the film roll sleeved on the air expansion shaft 130.

[0088] In this technical solution, the auxiliary feeding device 100 also includes a pusher. With the pusher in place, after the film roll is hoisted into position by the air shaft 130, the film roll can be pushed by the pusher. This allows the film roll to be moved into position more accurately, resulting in more precise film roll feeding.

[0089] In some examples, the pusher may include a drive component such as a cylinder or hydraulic cylinder.

[0090] In some examples, the height of the support 110 can be greater than or equal to 3m to meet the material loading requirements.

[0091] It should be noted that, as Figure 6 As shown, during material loading, if the first automatic loading / unloading module 240 and / or the second automatic loading / unloading module 250 malfunction, the auxiliary loading device 100 is activated. The air shaft 130 inserts to grip the raw material film roll and rises to the required height; simultaneously, the air shaft 130 on the other side (winding assembly 230) inserts to grip the empty core and rises to the required height, respectively inserting into the corresponding unwinding shaft 2211 or winding shaft 2311 to begin irradiation. Figure 7 As shown, during unloading, the air shaft 130 is in an uninflated state, and the air shaft 130 is coaxially aligned with the take-up shaft 2311 or the unwinding shaft 2211. The finished film roll on one side of the take-up assembly 230 is inserted into the air shaft 130 under the push of the push-out device on the take-up assembly 230 side, and the air shaft inflates and lowers to a predetermined height. At the same time, the tail film roll on the unwinding assembly 220 side is inserted into the air shaft 130 under the push of the push-out device on the unwinding assembly 220 side, and the air shaft inflates and lowers to a predetermined height, and is transferred to the conveyor line. The air shaft 130 deflates, and the finished film roll and the empty roll are placed on different conveyor belts and transported to their respective warehouses. Understandably, the ejection devices on the unwinding assembly 220 and the rewinding assembly 230 can be telescopic rods. A horizontal plate is vertically mounted on the end of the telescopic rod facing the film roll. This horizontal plate can cover the film rolls on the two unwinding shafts 2211 or the two rewinding shafts 2311. This single ejection device allows for the ejection of the film rolls from both shafts, simplifying the system structure. In this case, loading must be completed before unloading.

[0092] In this application, the loading and unloading of membrane rolls are achieved through the loading component 311 and unloading component 312 in the first automatic loading and unloading module 240 and the second automatic loading and unloading module 250. At the same time, when the loading component 311 is damaged, the robotic arm of the unloading component 312 can also perform loading operations, which improves the stability and reliability of the nuclear pore membrane irradiation and loading system. If the robotic arm 3121 malfunctions, the loading and unloading of membrane rolls can also be achieved through the auxiliary loading device 100. In this way, even when the loading component 311 and the unloading component 312 are under maintenance and repair, the nuclear pore membrane irradiation and loading system can still work normally, thereby improving irradiation efficiency.

[0093] In one feasible implementation, the irradiation and feeding system further includes: an accelerator beamline device 260, arranged at one end of the irradiation mechanism 210, with its output direction facing the irradiation mechanism 210; and an ion beam detector 270, which is disposed within the irradiation mechanism 210.

[0094] This technical solution further provides the structural composition of the irradiation and loading system for nuclear pore membranes. The system may also include an accelerator beamline device 260 and an ion beam detector 270. The accelerator beamline device 260 can provide an ion beam, and the ion beam detector 270 can detect the intensity of the heavy ion beam in real time. This pertains to the basic principles of nuclear pore membrane irradiation and will not be elaborated further.
