Description

Technical Field

[0001] This utility model relates to the technical field of optical tweezers printing devices, specifically an optical tweezers printing device for processing micro-nano structures. Background Technology

[0002] Optical tweezers printing devices are high-precision micro / nano manipulation systems based on optical tweezers technology. They capture, move, and align tiny particles using the gradient force of a laser beam, thereby assembling or printing complex structures. The core components include a high numerical aperture objective lens, a spatial light modulator, and a laser source. By dynamically modulating the beam phase using an optical tweezers (SLM), a multi-light trap array is generated, which can simultaneously manipulate hundreds of particles. These devices are typically combined with a microscopic imaging system to monitor the operation process in real time. They are suitable for fields such as single-cell manipulation, microfluidic chip construction, or nanomaterial assembly. The advantages of optical tweezers printing technology lie in its non-contact, non-destructive, and submicron-level resolution, providing a revolutionary tool for micro / nano manufacturing.

[0003] In existing technologies, optical tweezers printing devices control tiny particles through a laser beam to achieve complex printing effects. During the printing process, the laser beam inside the device generates high temperatures, resulting in hot printed products. Operators cannot directly handle the printed products at this time and must wait for them to cool down before removing them from the device, which is quite time-consuming. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an optical tweezers printing device for processing micro-nano structures, so as to solve the technical problem that the printed product is too hot after the printing device has finished working, making it difficult for the operator to remove it from the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an optical tweezers printing device for processing micro-nano structures, comprising a housing and a protective door, wherein the housing and the protective door are rotatably connected by a rotating shaft, a fixed seat is fixedly connected inside the housing by bolts, multiple sets of springs are fixedly connected inside the fixed seat, the fixed seat is elastically connected to a first extrusion block through multiple sets of springs, the fixed seat is elastically connected to multiple sets of second extrusion blocks through multiple sets of springs, and the first extrusion block is located on one side of the second extrusion block, a sliding groove is provided inside the fixed seat, and the fixed seat is slidably connected to a movable plate through the sliding groove, and a pull handle is fixedly connected to one end of the movable plate.

[0006] By adopting the above technical solution, this utility model solves the technical problem that after the printing device finishes working, the temperature of the printed product is too high, making it difficult for the operator to remove it from the device. The process involves placing printing material on the worktable, opening the protective door, and then pulling the handle. Once the movable plate is in place, its inclined surface at one end sequentially presses against the second and first pressing blocks, compressing the spring until the movable plate is fully inside the fixed seat. At this point, the inclined surface of the first pressing block continuously presses against the inclined plate of the movable plate. After closing the protective door, the fixing block on its side locks the handle through a groove, fixing the movable plate in place. Then, the device is started, and the laser printing mechanism emits a laser beam to capture and arrange tiny particles on the worktable. A transparent protective window allows for real-time observation of the printing process. After printing is complete, the protective door is opened to release the fixing block's restriction on the handle. The first pressing block, under the action of the spring, pushes the movable plate outward. Subsequently, the second pressing block, also reset by the spring, further pushes the movable plate to slide until the handle is partially removed from the housing. At this point, the movable plate can be directly pulled out and replaced with another worktable already loaded with material. This solves the technical problem that after the printing device finishes working, the printed product temperature is too high, making it difficult for the operator to remove it from the device.

[0007] Furthermore, a slope is provided on one side of the movable plate, and a slope is also provided on the top of the first extrusion block and the second extrusion block. The slope of the movable plate cooperates with the slope of the first extrusion block and the second extrusion block.

[0008] By adopting the above technical solution, after printing is completed, the user can open the protective door. At this time, the fixed block will release the restriction on the pull handle. Then, the first pressing block will press the inclined surface of the movable plate under the elastic action of the spring, causing the movable plate to move outward of the fixed seat. When the first pressing block reaches the limit position under the action of the spring, the inclined surface of the movable plate will contact the inclined surface of the second pressing block. At this time, the second pressing block will also rise under the action of the spring, so that the movable plate continues to slide outward of the fixed seat until the pull handle of the movable plate moves to the outside of the housing.

[0009] Furthermore, a workbench is fixedly connected to the top of the movable plate by bolts. The workbench is used to place the material to be printed. A laser printing mechanism is fixedly connected to the top of the inside of the housing. The laser printing mechanism is located directly above the fixed base. A protective window is fixedly connected inside the protective door. The protective window is made of transparent protective material.

[0010] By adopting the above technical solution, the equipment is started, and the laser printing mechanism emits a laser beam, which captures tiny particles on the worktable and causes them to move and arrange on the worktable. The protective window itself is made of transparent material, so the user can observe the printing process inside the shell through the protective window.

[0011] Furthermore, a fixing block is fixedly connected to one side of the protective door, and the fixing block has a groove that matches the size of the outer wall of the pull handle.

[0012] By adopting the above technical solution, when the protective door is closed, the fixing block on the side of the protective door has a groove that matches the pull handle. At this time, the fixing block will restrict the pull handle and fix the movable plate in the fixing seat.

[0013] In summary, this utility model has the following beneficial effects: By placing printing material on the worktable, opening the protective door, and pulling the handle to slide the movable plate into the fixed seat, the inclined surface at one end of the movable plate will sequentially press the second and first pressing blocks, compressing the spring until the movable plate is completely inside the fixed seat. At this time, the inclined surface of the first pressing block continues to press against the inclined plate of the movable plate. After closing the protective door, the fixed block on its side locks the handle through the groove, fixing the movable plate in place. Then, the device is started, and the laser printing mechanism emits a laser beam to capture and arrange the tiny particles on the worktable. The transparent protective window allows real-time observation of the printing process. After printing is completed, the protective door is opened to release the restriction of the fixed block on the handle. The first pressing block pushes the movable plate outward under the action of the spring. Then, the second pressing block also pushes the movable plate further through the spring reset until the handle is partially moved out of the housing. At this time, the movable plate can be directly pulled out and replaced with another worktable that has been loaded with material. This solves the technical problem that the printed product temperature is too high after the printing device has finished working, making it difficult for the operator to remove it from the device.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] An optical tweezers printing device for fabricating micro / nano structures, such as Figure 1-4 As shown, it includes a housing 1 and a protective door 2. The housing 1 and the protective door 2 are rotatably connected by a rotating shaft. A fixed seat 3 is fixedly connected inside the housing 1 by bolts. The fixed seat 3 is located inside the housing 1 and is used to place the movable plate 4.

[0022] Furthermore, a sliding groove is provided inside the fixed base 3, and the fixed base 3 is slidably connected to the movable plate 4 through the sliding groove. A pull handle 8 is fixedly connected to one end of the movable plate 4, wherein one end of the movable plate 4 is aligned with the inside of the fixed base 3, so that the movable plate 4 can slide into the fixed base 3.

[0023] Furthermore, multiple sets of springs 7 are fixedly connected inside the fixed base 3. The fixed base 3 is elastically connected to the first pressing block 5 through multiple sets of springs 7. The fixed base 3 is elastically connected to multiple sets of second pressing blocks 6 through multiple sets of springs 7. The first pressing block 5 is located on one side of the second pressing block 6. When the movable plate 4 is about to completely enter the fixed base 3, the inclined surface at one end of the movable plate 4 will first contact the second pressing block 6 and press it, thereby compressing the spring 7. The movable plate 4 continues to move into the fixed base 3, which will press multiple sets of second pressing blocks 6 until the first pressing block 5 is pressed. At this time, the movable plate 4 will reach the innermost part of the fixed base 3. At this time, the inclined surface of the first pressing block 5 will continue to press against the inclined plate of the movable plate 4.

[0024] In the example, a fixing block 9 is fixedly connected to one side of the protective door 2. The fixing block 9 has a groove that matches the size of the outer wall of the pull handle 8. When the protective door 2 is closed, the fixing block 9 on the side of the protective door 2 has a groove that matches the pull handle 8. At this time, the fixing block 9 will restrict the pull handle 8, so that the movable plate 4 is fixed in the fixing seat 3.

[0025] In the example, a workbench 10 is fixedly connected to the top of the movable plate 4 by bolts. The workbench 10 is used to place the material to be printed. A laser printing mechanism 11 is fixedly connected to the top of the inside of the housing 1. The laser printing mechanism 11 is located directly above the fixed base 3. A protective window 12 is fixedly connected to the inside of the protective door 2. The protective window 12 is made of transparent protective material.

[0026] The device is activated so that the laser printing mechanism 11 emits a laser beam, which captures tiny particles on the worktable 10 and causes them to move and align on the worktable 10. The protective window 12 itself is made of a transparent material, so the user can observe the printing process inside the housing 1 through the protective window 12.

[0027] In the example, the movable plate 4 has a slope on one side, and the top of the first pressing block 5 and the second pressing block 6 also have slopes. The slope of the movable plate 4 cooperates with the slopes of the first pressing block 5 and the second pressing block 6. After printing is completed, the user can open the protective door 2. At this time, the fixing block 9 will release the restriction on the pull handle 8. Then, the first pressing block 5 will press the slope of the movable plate 4 under the elastic action of the spring 7, causing the movable plate 4 to move outward of the fixed seat 3. When the first pressing block 5 reaches the limit position under the action of the spring 7, the slope of the movable plate 4 will contact the slope of the second pressing block 6. At this time, the second pressing block 6 will also rise under the action of the spring 7, so that the movable plate 4 continues to slide outward of the fixed seat 3 until the pull handle of the movable plate 4 moves to the outside of the housing 1.

[0028] The working principle of this utility model is as follows: When in use, the user can first take out the movable plate 4, place the material to be printed on the worktable 10 on the top of the movable plate 4, spread it evenly on the worktable 10, and then open the protective door 2.

[0029] At this time, by taking the pull handle 8 of the movable plate 4, one end of the movable plate 4 is aligned with the inside of the fixed seat 3, so that the movable plate 4 can slide into the fixed seat 3. When the movable plate 4 is about to be completely inserted into the fixed seat 3, the inclined surface of one end of the movable plate 4 will first contact the second pressing block 6 and press it, thereby compressing the spring 7.

[0030] As the movable plate 4 continues to move into the fixed base 3, it will squeeze multiple sets of second squeezing blocks 6 until it squeezes the first squeezing block 5. At this time, the movable plate 4 will reach the innermost part of the fixed base 3, and the inclined surface of the first squeezing block 5 will continue to press against the inclined plate of the movable plate 4.

[0031] When the movable plate 4 is moved into the fixed base 3, the protective door 2 can be closed at this time. The fixed block 9 on the side of the protective door 2 has a groove that matches the pull handle 8. At this time, the fixed block 9 will restrict the pull handle 8, so that the movable plate 4 is fixed in the fixed base 3.

[0032] The user can then start the device, causing the laser printing mechanism 11 to emit a laser beam, thereby capturing tiny particles on the worktable 10 and causing them to move and arrange on the worktable 10. The protective window 12 itself is made of transparent material, so the user can observe the printing inside the housing 1 through the protective window 12.

[0033] After printing is completed, the user can open the protective door 2. At this time, the fixing block 9 will release the restriction on the pull handle 8, and then the first pressing block 5 will press the inclined surface of the movable plate 4 under the elastic action of the spring 7, so that the movable plate 4 moves to the outside of the fixed seat 3.

[0034] When the first pressing block 5 reaches its limit position under the action of the spring 7, the inclined surface of the movable plate 4 will contact the inclined surface of the second pressing block 6. At this time, the second pressing block 6 will also rise under the action of the spring 7, so that the movable plate 4 continues to slide outward of the fixed seat 3 until the pull handle of the movable plate 4 moves to the outside of the housing 1.

[0035] At this point, the user can directly pull the handle 8 to remove the movable plate 4 from the fixed base 3, and then put another set of movable plates 4 with the worktable 10 into the housing 1, thereby saving the time of waiting for the printed product to cool down and improving work efficiency.

[0036] The above structure solves the technical problem that the printed product is too hot after the printing device finishes working, making it difficult for the operator to remove it from the device.
