Description

Technical Field

[0001] The invention belongs to the technical field of ultrafine functional materials, and in particular relates to a particle raft material processing device and a method thereof. Background Art

[0002] Particle raft is a kind of condensed soft matter with special properties formed by freely assembling many tiny particles on the liquid interface. Because the particles gathered on the water surface can support tiny objects like a raft, it is called a particle raft. It has applications in the fields of petroleum, chemical industry, medicine, bioengineering, etc. In the field of petroleum; in the chemical industry, fluorosilicon block copolymers can be synthesized by polymerization of particle rafts to make non-wetting coating materials; in the medical field, bionic nanovesicles can be synthesized by particle rafts, which can be used to load proteins or other biologically active cargoes, thus forming a targeted therapy for regenerative medicine. Depending on the reaction materials, particle rafts can also perform tasks such as drug delivery, and they play a very important role in drug treatment and other aspects.

[0003] Particle rafts have special super-hydrophobic properties, so how to manipulate particle rafts on the water surface is worth studying. In the literature of Yao et al. (Yao et al. Langmuir, 2023, 39(36): 12774-12784.), the movement of particle rafts was controlled by using surfactants. However, the injection of surfactants will pollute the water source, and it is impossible to repeat the experiment on the particle raft multiple times, causing irreversible damage to the particle raft. In the literature of Zuo et al. (Zuo et al. ActaMechanica Sinica, 2021: 1-6.), the mechanical contact method is used to control the deformation of the particle raft, but its disadvantage is that it requires contact with the particle raft, which is easy to damage the particle raft.

[0004] The particle raft can also be controlled by changing the material used to prepare the particles. In the literature by Zhang et al. (Zhang. Advanced materials, 2012, 24(35): 4756-4760), it is shown that adding magnetite to the material used to prepare the particles can control the movement of the particle raft through a magnetic field, but the disadvantage is that the particles are difficult to prepare due to material limitations. In the literature by Xu et al. (Xu. Applied Materials Today, 2020, 19: 100595), it is shown that due to the transmittance and absorbance of the particle raft material, it is feasible to use a near-infrared light source to push the particle raft to move. However, the article only uses a beam of near-infrared light source to simply move the particle raft to achieve the purpose of remote control, which only proves the feasibility of remote control of the particle raft and cannot be applied in practice. Summary of the invention

[0005] The purpose of the present invention is to design a particle raft material processing device and method thereof, by which the particle raft can be remotely controlled and processed, and the requirements for the particle raft material are relatively simple.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A particle raft material processing device, the device includes a first frame, a first cross rail is installed on the first frame, a second frame is arranged inside the first frame, the first frame and the second frame are not in contact, a second cross rail is installed on the second frame, a slider is installed on the cross rail, the slider has a control module that can control a laser irradiator to perform planar movement, a visual control system is installed below the slider, a laser irradiator is installed below the visual control system, and the incident angle of the laser irradiator irradiating the particle raft can be controlled by adjusting the observation angle of the visual system, and the control module includes a control board, a data transmission module, and a data processing module.

[0008] Furthermore, the frame is composed of aluminum profiles, right-angle connectors, supporting feet and connecting parts.

[0009] Furthermore, the cross rail includes a motor, a synchronous belt, an aluminum profile, an acrylic plate, and a pulley.

[0010] Furthermore, the laser is fixed on the slider and connected to the adjustment device for adjusting the irradiation angle and direction of the laser head.

[0011] Furthermore, the motor is connected to the synchronous wheel, which is then connected to the connecting plate, and then connected to the laser to form a horizontal rail driving mechanism.

[0012] A control method for a particle raft material processing device according to claim 1, the method being as follows:

[0013] Step 1: Place a container filled with water in the first frame of the device, and place particles on the water surface to self-assemble into a particle raft;

[0014] Step 2: Start the control module and move the two laser heads to the appropriate position so that the particle raft is within the focal length of the two lasers at the same time;

[0015] Step 3: Turn on the laser head, aim both lasers at the particle raft, and focus by observing the size of the laser spot irradiated on the particle raft. Adjust the laser power and focal length to make the laser spot as small and bright as possible;

[0016] Step 4: Turn off the laser, keep the laser focal length unchanged, and move the two laser beams to the initial position of the manipulated particle raft;

[0017] Step 5: Turn on the laser and adjust the power to the power adjusted in the above steps, so that the laser light reaches the minimum and brightest point again. At this time, the laser irradiates the water surface to increase the water surface temperature, change the surface tension of the water surface, and the particle raft floating on the water surface will move with the change of the surface tension of the water body;

[0018] Step 6: Control the position and angle of the two laser beams irradiating the water surface through the control module to change the water temperature, thereby controlling the entire particle raft to move and cut, or extrude and stack part of the particle raft to merge it into a whole.

[0019] The following beneficial effects can be obtained through the above technical solution:

[0020] The device designed by this patent for controlling the movement of the particle raft has a simple structure and low cost. It can not only remotely control the particle raft to move simply on the water surface, but also cut and fuse the particle raft to achieve complex movements, without affecting the water quality and with low requirements for particle materials. It can solve the problems of cutting, squeezing and moving the particle raft on the water surface, and put the particle raft into application. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is combined with Figure 1-4 The present invention is further described as follows:

[0026] like Figure 2 As shown, a particle raft material processing device comprises a first frame, a first cross rail is installed on the first frame, a second frame is arranged inside the first frame, the first frame and the second frame are not in contact, a second cross rail is installed on the second frame, a slider is installed on the cross rail, the slider 6 is equipped with a control module that can control the laser irradiator 9 to perform planar movement, a visual control system 7 is installed under the slider, a laser irradiator is installed under the visual control system, and the incident angle of the laser irradiator irradiating the particle raft can be controlled by adjusting the observation angle of the visual system, and the control module comprises a control board, a data transmission module, and a data processing module.

[0027] The frame consists of aluminum profiles, right-angle connectors, support feet and connecting parts.

[0028] The cross rail includes a motor, a synchronous belt, an aluminum profile, an acrylic plate, and a pulley.

[0029] The laser is fixed on the slider and connected to the adjusting device for adjusting the irradiation angle and direction of the laser head.

[0030] The motor is connected to the synchronous wheel, and then to the connecting plate, and then to the laser to form a horizontal rail driving mechanism.

[0031] A control method for a particle raft material processing device according to claim 1, the method being as follows:

[0032] Step 1: Place a container filled with water in the first frame of the device, and place particles on the water surface to self-assemble into a particle raft;

[0033] Step 2: Start the control module and move the two laser heads to the appropriate position so that the particle raft is within the focal length of the two lasers at the same time;

[0034] Step 3: Turn on the laser head, aim both lasers at the particle raft, and focus by observing the size of the laser spot irradiated on the particle raft. Adjust the laser power and focal length to make the laser spot as small and bright as possible;

[0035] Step 4: Turn off the laser, keep the laser focal length unchanged, and move the two laser beams to the initial position of the manipulated particle raft;

[0036] Step 5: Turn on the laser and adjust the power to the power adjusted in the above steps, so that the laser light reaches the minimum and brightest point again. At this time, the laser irradiates the water surface to increase the water surface temperature, change the surface tension of the water surface, and the particle raft floating on the water surface will move with the change of the surface tension of the water body;

[0037] Step 6: Control the position and angle of the two laser beams irradiating the water surface through the control module to change the water temperature, thereby controlling the entire particle raft to move and cut, or extrude and stack part of the particle raft to merge it into a whole.

[0038] Example 1: Please refer to Figure 2A laser control device for a particle raft includes a frame, a control system, a visual control system and an irradiation device. The frame is composed of an aluminum profile 1, an acrylic plate 2, a right-angle connector 3 and a support leg 4. Specifically, four aluminum profiles 1 are used to form a square frame. The right-angle connector 3 and the support leg 4 are arranged at the connection of the four aluminum profiles 1. The acrylic plate 2 can slide on the aluminum profile 1 through its own slide 8. Two acrylic plates 2 are installed on both sides of the square frame. The two acrylic plates 2 are connected by a cross rail 5. A slider 6 is installed on the cross rail 5. The slider 6 has a control module that can control the laser irradiator 9 to move in a plane. A visual control system 7 is installed under the slider. The laser irradiator is installed under the visual control system to adjust the position and angle during irradiation.

[0039] Based on the above frame structure, a first frame and a second frame structure are designed respectively. The first frame and the second frame structure are the same, but the size of the first frame is completely larger than the second frame. The arrangement relationship between the two is that the second frame is placed in the first frame, and the two are completely non-contacting, and the sliding rail and the slider of the first frame are both located above the first frame and do not contact.

[0040] Embodiment 2, Figure 3 As shown, a method for controlling a particle raft laser control system is applied to the laser controller for controlling the particle raft in Example 1, and comprises the following steps:

[0041] Step 1: Place a container filled with water in the first frame of the device, and place particles on the water surface to self-assemble into a particle raft;

[0042] Step 2: Start the control module and move the two laser heads to the appropriate position so that the particle raft is within the focal length of the two lasers at the same time;

[0043] Step 3: Turn on the laser head, aim both lasers at the particle raft, and focus by observing the size of the laser spot irradiated on the particle raft. Adjust the laser power and focal length to make the laser spot as small and bright as possible;

[0044] Step 4: Turn off the laser, keep the laser focal length unchanged, and move the two laser beams to the initial position of the manipulated particle raft;

[0045] Step 5: Turn on the laser and adjust the power to the power adjusted in the above steps, so that the laser light reaches the minimum and brightest point again. At this time, the laser irradiates the water surface to increase the water surface temperature, change the surface tension of the water surface, and the particle raft floating on the water surface will move with the change of the surface tension of the water body;

[0046] Step 6: Control the position and angle of the two laser beams irradiating the water surface through the control module to change the water temperature, thereby controlling the entire particle raft to move and cut, or extrude and stack part of the particle raft to merge it into a whole.

[0047] Figure 1 As shown, the specific movement of the particle raft is as follows:

[0048] cutting of particle rafts;

[0049] Through the visual feedback system of two cameras, the two cameras are moved to the bottom of the particle raft; the first laser slowly moves from the bottom to the top of the particle raft; the second laser moves following the movement route of the first laser; when the two lasers move to the same position, they move to the left and right sides of the particle raft at the same time for cutting; after cutting the ideal gap, they stop and turn off the power.

[0050] Extruding the particle raft;

[0051] Move the two cameras to the left and right sides of the particle raft through the visual feedback system of the two cameras; control the two cameras to move and extrude toward the center of the particle raft through the control system; track the edge of the particle raft through the visual system; stop and turn off the power after the particle raft is extruded to the ideal thickness;

[0052] Moving the particle raft;

[0053] Move the two cameras to the bottom of the particle raft through their visual feedback system; manipulate the two cameras simultaneously through the control system to push the particle raft to move as a whole; track the edge of the particle raft through vision; change the incident angle and moving route of the two cameras through the control system to achieve a more precise movement of the particle raft; and stop and turn off the power after the particle raft moves to the ideal position.

[0054] The present invention uses infrared laser to heat the liquid interface, thereby remotely controlling the particle raft through the Maracas force, which has low requirements on the materials for preparing the particle raft and will not pollute the liquid. The device is not only simple in structure and easy to operate, but also can remotely control the particle raft, and the requirements on the material of the particle raft are also relatively simple.

[0055] The composite system of particle rafts consists of particles and liquid interfaces. Precisely controlling the movement and deformation of particle rafts is a difficult problem in this field. This patent designs a control system and method that uses infrared lasers to heat the liquid interface, thereby controlling the particle raft through Malagon force. The particle raft can be remotely controlled to move simply on the water surface, and can also be cut, fused, and other effects to achieve complex movements. It will not affect the water quality and has low restrictions on particle materials. This solves the problems of cutting, extruding, and moving the particle raft on the water surface, laying the foundation for the further processing and application of the particle raft.

[0056] The above are all preferred embodiments of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
