Description

Technical Field

[0001] This invention belongs to the field of laser processing, specifically relating to an ultrafast laser processing system and method for preparing two-dimensional material nanostructures. Background Technology

[0002] Novel graphene-like two-dimensional materials have wide applications in electronics, optoelectronics, sensing, catalysis, and energy conversion. Natural two-dimensional materials are abundant and inexpensive, but their bulk form is inert, meaning they have low chemical activity, which is detrimental to chemical and biological applications such as chemical catalysis, biosensing, and energy conversion. Unlike bulk materials, two-dimensional nanostructures possess numerous active sites on their edges and surfaces, which are advantageous for chemical and biological applications. Furthermore, two-dimensional materials, such as transition metal sulfides, are intrinsically semiconductor in nature, while metallic transition metal sulfides exhibit higher electrical conductivity and photoexcitation properties.

[0003] Methods for preparing two-dimensional nanostructures of transition metal sulfides include hydrothermal methods and exfoliation methods; exfoliation methods include chemical intercalation exfoliation, electrochemical intercalation exfoliation, and microwave-assisted exfoliation. These methods require various chemical reagents, complex steps, and specific environments such as particular temperatures and pressures. The resulting nanostructures exhibit poor crystallinity, common shapes, and lack of metallic phase transitions.

[0004] Fast laser processing is a novel technology in the field of micro- and nano-manufacturing. Laser processing methods are fast, flexible, non-contact, pollution-free, and do not require harsh conditions. Ultrafast lasers, in particular, have advantages such as short pulse duration, high peak pulse power, the ability to avoid thermal effects and prevent thermal oxidation of materials, and precise focusing for positioning and processing.

[0005] Current laser processing equipment for fabricating two-dimensional nanostructures suffers from several drawbacks. Firstly, the equipment may not be level before processing, resulting in misalignment between the equipment and the workpiece. This leads to tilted grooves and holes during laser processing, negatively impacting the processing results. Secondly, impurities on the workpiece surface can affect its flatness, further hindering the processing. Therefore, improvements are necessary. Summary of the Invention

[0006] The purpose of this invention is to provide an ultrafast laser processing system and method for the preparation of two-dimensional material nanostructures, which solves the problems of unevenness between the equipment and the workpiece affecting the grooving and hole cutting effect, and unevenness of the workpiece surface affecting the processing effect.

[0007] To achieve the above objectives, this invention provides an ultrafast laser processing system for the fabrication of two-dimensional material nanostructures, comprising an adjustment and calibration module, a workpiece clamping module, a laser processing module, a laser beam expanding module, an adjustment and control module, a processing prompt module, and an information recording module. The user terminal module is connected to the command transmission module, allowing the user terminal to transmit operation commands. The command transmission module is connected to the operation control module, enabling the transmission of user-sent control commands to the operation control module for execution. The operation control module is connected to the equipment detection module, enabling the detection of the laser processing equipment.

The system adjusts and calibrates to address issues. The operation control module is connected to the workpiece clamping module, enabling the execution of operation commands and workpiece positioning and clamping. It is also connected to the laser processing module, sending commands to perform processing. The laser processing module is connected to the laser beam expander, expanding the emitted laser beam. The operation control module is connected to the adjustment control module, allowing adjustment of the processing equipment's height, mask, and horizontal position. The operation control module is connected to the processing prompt module, providing feedback on processing completion information. Finally, the processing prompt module is connected to the information recording module, storing and recording processing logs and data.

[0008] The principle of this invention is as follows: When the equipment is in use, the workpiece is first placed on the rotating wheel, and then the hydraulic cylinder is started. The output end of the hydraulic cylinder drives the push rod to move upward, and the push rod drives the inclined block to move. The inclined block slides relative to the pulley, and the inclined block drives the hinge rod to rotate. The hinge rod slides along the fixed rod, and the hinge rod compresses the spring, which can realize the deflection of the clamping wheel towards the workpiece, so that the clamping wheel contacts the workpiece, and the workpiece can be clamped and positioned. Moreover, the clamping wheels at both ends move synchronously, which can center and clamp the workpiece with high positioning accuracy, thereby improving the laser processing effect.

[0009] The beneficial effects of this invention are as follows: By designing the equipment detection module, the working status of the laser processing equipment can be detected, including levelness, flatness, and functionality. Combined with the adjustment and calibration module, the processing equipment can be adjusted and calibrated to maintain its optimal working condition and prevent tilting of the equipment or unevenness of the workpiece from affecting the laser processing effect. The laser beam expanding module expands the laser beam, resulting in a uniform laser spot energy distribution, smooth edges on the cut workpiece, and better processing results. Simultaneously, the adjustment and control module allows for the adjustment of various processing parameters, improving the equipment's adaptability.

[0010] By designing the function of the hydraulic cylinder, the output end of the hydraulic cylinder can drive the push rod to move vertically. The push rod simultaneously drives the inclined block to move. Through the sliding connection between the pulley and the inclined block and the hinge connection between the hinge rod and the machine body, the clamping wheel can be deflected towards the workpiece. Moreover, the clamping wheels at both ends move synchronously, which can center and clamp the workpiece with high positioning accuracy, thereby improving the laser processing effect.

[0011] Furthermore, the equipment testing module includes a leveling testing module, a flatness testing module, and a function self-testing module. The leveling testing module and the flatness testing module are connected, and the flatness testing module and the function self-testing module are connected.

[0012] Furthermore, the adjustment and calibration module includes a leveling adjustment module, a flatness adjustment module, and a manual calibration module. The leveling adjustment module and the flatness adjustment module are connected, and the flatness adjustment module and the manual calibration module are connected. Through the adjustment and calibration module, the detected problems can be adjusted and calibrated.

[0013] Furthermore, the laser beam expanding module includes a beam expanding mirror module, a transmission-reflecting prism module, and a focusing lens module. The beam expanding mirror module and the transmission-reflecting prism module are connected, and the transmission-reflecting prism module and the focusing lens module are connected. The laser beam expanding module can expand the emitted laser beam.

[0014] Furthermore, the adjustment control module includes a lifting control module, a mask adjustment module, and a lens offset module. The lifting control module and the mask adjustment module are connected, and the mask adjustment module and the lens offset module are connected. Through the adjustment control module, different working parameters of the processing equipment can be adjusted.

[0015] Furthermore, it also includes a machine body, the bottom of which is fixedly connected to four evenly distributed support bases, the front end of which has a heat dissipation vent, the right end of which is hinged to an inspection door, the top of which is bolted to a mounting base, the top of which is fixedly connected to a bracket, the front end of which is fixedly connected to a laser, the lower end of which is provided with an emitting head, and the machine body is provided with a clamping mechanism.

[0016] Furthermore, the clamping mechanism includes hydraulic cylinders. Two symmetrically distributed hydraulic cylinders are fixedly connected inside the machine body. A push rod is fixedly connected to the upper end of the output end of each hydraulic cylinder. The push rod is slidably connected to the machine body. A rotating wheel is hinged inside the upper end of the push rod. Wedges are fixedly connected to both ends of the push rod. A pulley is contacted on the upper surface of each wedge. A hinge rod is rotatably sleeved on the outer side of the pulley. The hinge rod is rotatably connected to the machine body via a hinge shaft. A clamping wheel is hinged inside the upper end of the hinge rod. A fixing rod is fixedly connected to the inner wall of the machine body. The fixing rod is slidably connected to the hinge rod. A spring is provided on the outer side of the fixing rod. By designing this clamping mechanism, the workpiece positioning and clamping effect can be improved.

[0017] Furthermore, a through groove is provided inside the hinge rod, and a fixed rod is slidably connected inside the through groove. By designing the through groove, the fixed rod can slide relative to the hinge rod.

[0018] Furthermore, one end of the spring is fixedly connected to the inner wall of the machine body, and the other end of the spring is fixedly connected to the hinge rod. By designing the spring, the spring force can be applied to the hinge rod.

[0019] The method of using an ultrafast laser processing system for fabricating two-dimensional material nanostructures includes the following specific steps:

[0020] Step 1: First, place the workpiece on the worktable surface of the laser processing equipment using a robotic arm or manually. Then, the user logs into the user terminal module to operate the port, inputting the spatial requirements, processing parameters, and data information. The user's input commands are sent through the command transmission module.

[0021] Step 2: The operation control module receives the operation instruction information. At this time, the operation control module first sends the execution instruction to the workpiece clamping module. Then, the workpiece clamping module clamps and positions the workpiece on the worktable surface. After clamping is completed, the operation control module sends the operation instruction to the equipment detection module.

[0022] Step 3: After receiving the instruction, the equipment detection module performs the detection. First, the level detection module detects the levelness of the equipment, and then the flatness detection module detects the flatness of the workpiece surface to determine whether there are any impurities or obstructions. At the same time, the function self-test module can perform self-testing of the basic functions of the laser processing equipment to determine whether it is in normal working condition.

[0023] Step 4: After the equipment test is completed, if a problem message is found, an instruction will be sent to the adjustment and calibration module. The horizontal adjustment module will adjust the levelness of the equipment, and the flatness adjustment module will adjust the flatness of the workpiece surface. If the adjustment equipment malfunctions, manual adjustment and calibration will be performed through the manual calibration module.

[0024] Step 5: After the equipment inspection and adjustment are completed, the operation control module sends an instruction to the laser processing module to start the laser processing of the workpiece. After the laser is emitted, it is expanded by the laser beam expansion module. After the beam is expanded, the laser can process the workpiece. During the processing, the adjustment control module can also be used to adjust and control the workpiece. The lifting control module adjusts the distance between the lens and the workpiece, the mask adjustment module adjusts the focusing position, and the lens offset module adjusts the lens position.

[0025] Step Six: After the laser processing of the workpiece is completed, the operation control module sends a command to the workpiece clamping module to release the workpiece from positioning. At the same time, the processing prompt module sends feedback information to the user terminal module to indicate the completion of the processing. Finally, the information recording module records and stores the processing log and data information during the processing, thus completing the entire processing work. Attached Figure Description

[0042] The method of using an ultrafast laser processing system for fabricating two-dimensional material nanostructures includes the following specific steps:

[0043] Step 1: First, place the workpiece on the worktable surface of the laser processing equipment using a robotic arm or manually. Then, the user logs into the user terminal module 10 to operate the port, inputting the spatial requirements, processing parameters, and data information.

[0048] Step Six: After the laser processing of the workpiece is completed, the operation control module 12 sends an instruction to the workpiece clamping module 15 to release the workpiece positioning. At the same time, the processing prompt module 19 sends feedback information to the user terminal module 10 to indicate the completion of the processing. Finally, the information recording module 20 records and stores the processing log and data information during the processing, thus completing all the processing work.

[0049] In another embodiment, such as Figure 6 , Figure 7 , Figure 8 As shown, the ultrafast laser processing system for fabricating two-dimensional material nanostructures also includes a body 1.

At the same time, through the adjustment and control module 18, various processing parameters can be adjusted to improve the adaptability of the equipment.

[0055] By designing the function of hydraulic cylinder 91, the output end of hydraulic cylinder 91 can drive push rod 92 to move vertically. Push rod 92 simultaneously drives inclined block 94 to move. Through the sliding connection between pulley 95 and inclined block 94 and the hinge rod 96 and machine body 1, the clamping wheel 98 can be deflected towards the workpiece. Moreover, the clamping wheels 98 at both ends move synchronously, which can center and clamp the workpiece with high positioning accuracy, thereby improving the laser processing effect.

8. An ultrafast laser processing method for fabricating two-dimensional material nanostructures, characterized in that: The system described in any one of claims 1-7 is employed, and the specific steps include: Step 1: First, place the workpiece on the worktable surface of the laser processing equipment using a robotic arm or manually. Then, the user logs into the user terminal module to operate the port, inputting the spatial requirements, processing parameters, and data information. The user's input commands are sent through the command transmission module. Step 2: The operation control module receives the operation instruction information. At this time, the operation control module first sends the execution instruction to the workpiece clamping module. Then, the workpiece clamping module clamps and positions the workpiece on the worktable surface. After clamping is completed, the operation control module sends the operation instruction to the equipment detection module. Step 3: After receiving the instruction, the equipment detection module performs the detection. First, the level detection module detects the levelness of the equipment, and then the flatness detection module detects the flatness of the workpiece surface to determine whether there are any impurities or obstructions. At the same time, the function self-test module can perform self-testing of the basic functions of the laser processing equipment to determine whether it is in normal working condition. Step 4: After the equipment test is completed, if a problem message is found, an instruction will be sent to the adjustment and calibration module. The horizontal adjustment module will adjust the levelness of the equipment, and the flatness adjustment module will adjust the flatness of the workpiece surface. If the adjustment equipment malfunctions, manual adjustment and calibration will be performed through the manual calibration module. Step 5: After the equipment inspection and adjustment are completed, the operation control module sends an instruction to the laser processing module to start the laser processing of the workpiece. After the laser is emitted, it is expanded by the laser beam expansion module. After the beam is expanded, the laser can process the workpiece. During the processing, the adjustment control module can also be used to adjust and control the workpiece. The lifting control module adjusts the distance between the lens and the workpiece, the mask adjustment module adjusts the focusing position, and the lens offset module adjusts the lens position. Step Six: After the laser processing of the workpiece is completed, the operation control module sends a command to the workpiece clamping module to release the workpiece from positioning. At the same time, the processing prompt module sends feedback information to the user terminal module to indicate the completion of the processing. Finally, the information recording module records and stores the processing log and data information during the processing, thus completing the entire processing work.
