Description

Technical Field

[0001] This utility model relates to the field of nuclear pore membrane module production technology, specifically a loading device for automated production of nuclear pore membrane module assemblies. Background Technology

[0002] Nuclear pore membranes are thin film materials with unique pore sizes and shapes. They utilize the powerful penetrating force generated by the acceleration of atomic nuclei in high-energy accelerators, combined with cutting-edge chemical technology, to form dense, uniformly sized cylindrical or other porous thin film materials from PET film. As a high-precision microporous material, nuclear pore membranes have been applied in various fields related to people's lives, including medical, pharmaceutical, environmental protection, food and chemical industries, cell detection membranes, and analysis. During the production and use of finished nuclear pore membranes, the mother and daughter components need to be fixed in matching clamps to obtain qualified nuclear pore membrane assemblies. To accelerate the production efficiency of nuclear pore membrane assemblies, existing production equipment produces multiple assemblies simultaneously. After production, assembly loading equipment is needed to collect and transport the processed nuclear pore membrane assemblies for subsequent processing.

[0003] However, most existing nuclear pore membrane assembly loading devices have several placement slots on the device for mounting the nuclear pore membrane assembly. In actual use, when the nuclear pore membrane assembly production equipment places the nuclear pore membrane assembly on the loading device, it is easy to cause problems such as misalignment and cracking, resulting in low yield. This not only affects production efficiency but also increases production costs.

[0004] Based on this, a loading device for automated production of nuclear pore membrane assembly assemblies is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide an assembly loading device for automated production of nuclear pore membrane assembly, so as to solve the problem in the prior art that it is inconvenient to protect and position nuclear pore membrane assembly without an assembly loading device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A loading fixture for automated production of nuclear pore membrane assembly units includes a loading plate. The loading plate has a rectangular array of several placement slots. Four positioning grooves are arranged in an array around the placement slots. Positioning sliders are slidably mounted inside each positioning groove. A first return spring is provided between one side of each positioning slider and the inside of each positioning groove. A stop post is abutted against the other side of each positioning slider and fixedly mounted at the bottom end of each positioning groove. A fixing rod is fixedly mounted at the bottom end of each positioning slider. A limiting groove is provided at the bottom end of the loading plate corresponding to the position of the fixing rod. Installation grooves are symmetrically arranged at the bottom end of the loading plate, and each installation groove contains a pushing mechanism for simultaneously moving several positioning sliders.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] In one alternative embodiment: the pushing mechanism includes sliding levers, with sliding levers symmetrically arranged in both mounting slots. Each of the fixed rods in the same row is tightly attached to one side of a sliding lever. Each sliding lever has sliding holes at both ends. Guide rods are symmetrically arranged in each mounting slot. Each end of the sliding lever is slidably mounted on one of the two guide rods. Fixed rotating seats are fixedly mounted at both ends of the sliding levers. Connecting rods are hinged to the fixed rotating seats. Connecting rods on the same side of the two sliding levers are hinged to both ends of a hinge rod. A sliding rod is fixedly mounted at one end of each hinge rod. The sliding rods are slidably mounted inside the loading plate. A push plate is fixed between the sliding rods on the same side. A sliding groove is provided on one side of the loading plate corresponding to the push plate position. One side of the push plate is fixedly connected to one end of each of two second return springs. The other end of each second return spring is fixedly connected to the inside of the sliding groove. The two second return springs are coaxially arranged with the two sliding rods. A fixing component is provided inside the loading plate to fix the working position of the push plate.

[0010] In one alternative embodiment: the fixing component includes a connecting block, and a connecting block is fixedly provided on one side of the push plate. A stop frame is slidably provided inside each connecting block. A barb is fixedly provided at one end of the stop frame, and a circular plate is fixedly provided on the stop frame. A sliding groove is provided inside the connecting block at a position corresponding to the circular plate. A third return spring is provided between the upper end of the circular plate and the inside of the sliding groove. A fixing plate is fixedly provided at the other end of the stop frame. A sliding notch is provided at the bottom end of the loading plate at a position corresponding to the fixing plate. A limiting frame is provided inside the loading plate at a position corresponding to the upper end of the stop frame.

[0011] In one alternative: a downward pressure rod is fixedly provided at the upper end of the limiting frame, the downward pressure rod is slidably disposed inside the loading plate, a pressing post is fixedly provided at one end of the downward pressure rod, a downward pressure groove is provided inside the loading plate at the position corresponding to the pressing post, and a fourth reset spring is provided between the bottom end of the pressing post and the downward pressure groove.

[0015] This invention features positioning grooves around several placement slots, with positioning sliders slidably mounted inside each groove. A first return spring is installed between one side of each positioning slider and one side of each positioning groove. This ensures rapid positioning of the mother component within different sized nuclear pore membrane assemblies within the acceptable error range. It prevents misalignment of the membrane and mother component due to dimensional deviations during automated production, which could lead to membrane displacement or damage in the final semi-finished nuclear pore membrane assembly. When the processing component moves away from the loading plate, the first return springs ensure the positioning sliders are in close contact with the nuclear pore membrane assembly, pushing the assembly to move and making it coaxial with the placement slot. Furthermore, a pushing mechanism allows for simultaneous movement of several positioning sliders, moving them away from the nuclear pore membrane assembly and facilitating its removal. This enhances the practicality of the nuclear pore membrane assembly loading fixture. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-6 As shown, a loading fixture for automated production of nuclear pore membrane assembly includes a loading plate 11. The loading plate 11 has a rectangular array of several placement slots 12. Four positioning grooves 14 are arranged on the loading plate 11 with the placement slots 12 as centers. Positioning sliders 13 are slidably mounted inside each positioning groove 14. A first return spring 15 is provided between one side of each positioning slider 13 and the inside of each positioning groove 14. A stop post 16 is tightly attached to the other side of each positioning slider 13 and is fixedly mounted in the positioning groove 14. 4. At the bottom of the inner end, each of the positioning sliders 13 is fixedly provided with a fixing rod 17. Each of the loading plates 11 is provided with a limiting groove 18 at the position corresponding to the fixing rod 17. The bottom of the loading plate 11 is symmetrically provided with mounting grooves. Each mounting groove is provided with a pushing mechanism for pushing several positioning sliders 13 to move simultaneously. The pushing mechanism facilitates the simultaneous movement of several positioning sliders 13, so that the positioning sliders 13 are away from the nuclear pore membrane assembly inside the placement groove 12, thereby facilitating the removal of the nuclear pore membrane assembly loaded on the loading plate 11.

[0025] The pushing mechanism includes sliding levers 19, with symmetrical sliding levers 19 arranged in both mounting slots. Each of the fixed rods 17 in the same row is tightly attached to one side of a sliding lever 19. Each sliding lever 19 has sliding holes at both ends. Guide slide rods are symmetrically arranged in each mounting slot. Each end of the sliding lever 19 is slidably mounted on one of the two guide slide rods. Fixed rotating seats are fixed at both ends of each sliding lever 19. Connecting rods 20 are hinged to each fixed rotating seat. The connecting rods 20 on the same side of the two sliding levers 19 are hinged to both ends of a hinge rod 21. Each chain rod 21 has a sliding rod fixedly provided at one end. The sliding rod is slidably disposed inside the loading plate 11. A push plate 23 is fixedly provided between the sliding rods on the same side. A sliding groove is provided on one side of the loading plate 11 at a position corresponding to the push plate 23. One side of the push plate 23 is fixedly connected to one end of two second return springs 22, and the other end of the second return springs 22 is fixedly connected to the inner side of the sliding groove. The two second return springs 22 are respectively coaxially arranged with the two sliding rods. In use, when the processing component places several nuclear pore membrane assemblies on several placement grooves 12 at the upper end of the loading plate 11, the assembly is used to place several nuclear pore membrane assemblies. Inside, the diameter of the placement groove 12 is larger than the diameter of the nuclear pore membrane assembly, which reduces the risk of the nuclear pore membrane assembly being cracked during placement of the processed part. Simultaneously, during placement, the positioning sliders 13 slide within the positioning grooves 14. When the processed part moves away from the upper end of the loading plate 11, under the action of the first return spring 15, all four positioning sliders 13 are in close contact with the nuclear pore membrane assembly, thus positioning the nuclear pore membrane assembly inside the placement groove 12. After processing, when multiple nuclear pore membrane assemblies need to be removed from the loading plate 11, the user pushes two push plates 23 respectively, and the two push plates 23 respectively move four... The sliding rods slide, and the four sliding rods drive the four hinge rods 21 to slide respectively. The four hinge rods 21 push the four sliding levers 19 to move through the eight connecting rods 20, so that the sliding levers 19 move along the axis of the guide rod. The two sliding levers 19 in the same mounting slot move in opposite directions. The sliding levers 19 push the positioning slider 13 to slide through the fixing rod 17, so that the positioning slider 13 moves away from the nuclear pore membrane assembly inside the placement slot 12, thereby facilitating the removal of the nuclear pore membrane assembly. The loading plate 11 is provided with a fixing component for fixing the working position of the push plate 23.

[0026] The fixing component includes a connecting block 24. A connecting block 24 is fixedly provided on one side of the push plate 23. A stop frame 25 is slidably provided inside each connecting block 24. A barb is fixedly provided at one end of each stop frame 25, and a circular plate is fixedly provided on the stop frame 25. A sliding groove is provided inside the connecting block 24 at a position corresponding to the circular plate. A third return spring 26 is provided between the upper end of the circular plate and the sliding groove. A fixing plate 27 is fixedly provided at the other end of the stop frame 25. A sliding notch is provided at the bottom end of the loading plate 11 at a position corresponding to the fixing plate 27. The interior of the loading plate 11 and the upper end of the stop frame 25... A limiting frame 28 is provided at the end position. When in use, when the user pushes the push plate 23 to move, so that the positioning slider 13 moves away from the nuclear pore membrane assembly, and the nuclear pore membrane assembly needs to be removed one by one, the working position of the push plate 23 needs to be fixed. At this time, the user pushes the fixed plate 27 to move while pushing the push plate 23. When the push plate 23 reaches the working position, one end of the stop bracket 25 is inserted into the limiting frame 28. Then the fixed plate 27 is released. Under the action of the third return spring 26, the barb of one end of the stop bracket 25 is pressed tightly against one side of the limiting frame 28, thereby fixing the working position of the push plate 23.

[0027] The upper end of the limiting frame 28 is fixedly provided with a pressing rod, which is slidably disposed inside the loading plate 11. One end of the pressing rod is fixedly provided with a pressing post 29. The loading plate 11 is provided with a pressing groove corresponding to the position of the pressing post 29. A fourth return spring 30 is provided between the bottom end of the pressing post 29 and the pressing groove. In use, when the nuclear pore membrane assembly inside the placement slot 12 is being unloaded, the loading plate 11 needs to be placed on the processing table. After the nuclear pore membrane assembly is processed, it is inconvenient to press the fixed plate 27 to return the push plate 23 to its initial position. At this time, the user presses the pressing post 29, which drives the limiting frame 28 to slide through the pressing rod, causing the limiting frame 28 to disengage from the barb at one end of the stop frame 25. Under the action of the second return spring 22, the push plate 23 drives the connecting block 24 back to its initial position, thereby causing several positioning sliders 13 to return to their working positions.

[0028] Both sides of the positioning slider 13 are fixed with stop blocks, and the inner side of the positioning groove 14 is provided with grooves corresponding to the positions of the stop blocks, so as to restrict the position of the positioning slider 13 during use.

[0029] The bottom end of the fixing plate 27 is at the same height as the bottom end of the loading plate 11, and the fixing rod 17 has a circular cross-section. In use, the bottom end of the fixing plate 27 and the bottom end of the loading plate 11 are at the same height, which makes it easy to prevent the fixing plate 27 from being damaged when several loading plates 11 are stacked. At the same time, the circular cross-section of the fixing rod 17 makes it easy for the sliding lever 19 to push the positioning slider 13 to move through the fixing rod 17.

[0030] The above embodiment discloses a loading fixture for automated production of nuclear pore membrane assembly assemblies. When a processing component places several nuclear pore membrane assemblies into several placement slots 12 on the upper end of a loading plate 11, the diameter of the placement slots 12 is larger than the diameter of the nuclear pore membrane assemblies. This reduces the risk of the nuclear pore membrane assemblies being cracked during placement. Simultaneously, during placement, positioning sliders 13 slide within positioning grooves 14. When the processing component moves away from the upper end of the loading plate 11, under the action of a first return spring 15, all four positioning sliders 13 are in close contact with the nuclear pore membrane assemblies, thus positioning the nuclear pore membrane assemblies within the placement slots 12. After processing, when multiple nuclear pore membrane assemblies need to be removed from the loading plate 11, the user pushes two push plates 23, which in turn drive four sliding rods to slide. These four sliding rods, in turn, drive four hinge rods 21 to slide. The four hinge rods 21, through eight connecting rods 20, push four sliding levers 19 to move, causing the sliding levers 19 to... The guide slide rod moves along the axis of the guide slide rod, and the two sliding levers 19 inside the same mounting groove move in opposite directions. The sliding lever 19 pushes the positioning slider 13 to slide through the fixing rod 17, so that the positioning slider 13 moves away from the nuclear pore membrane assembly inside the placement groove 12. At the same time, it pushes the fixing plate 27 to move. When the push plate 23 reaches the working position, one end of the stop bracket 25 is inserted into the limit frame 28. Then the fixing plate 27 is released. Under the action of the third return spring 26, the barb at one end of the stop bracket 25 is pressed tightly against one side of the limit frame 28, thereby fixing the working position of the push plate 23. When it is necessary to return several positioning sliders 13 to the working position, the pressing column 29 is pressed. The pressing column 29 drives the limit frame 28 to slide through the pressing rod, so that the limit frame 28 is disengaged from the barb at one end of the stop bracket 25. Under the action of the second return spring 22, the push plate 23 drives the connecting block 24 back to the initial position, so that several positioning sliders 13 return to the working position.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
