Description

Technical Field

[0001] The present application relates to the technical field of coating preparation, and in particular to a self-assembly coating preparation platform. Background Art

[0002] With the gradual development of self-assembled coating technology, other types of interaction forces such as hydrogen bonds and covalent bonds between macromolecules are widely used. At the same time, compared with traditional coatings that rely on the release of non-polar metal ions into the environment to kill bacteria, self-assembled coatings ensure antibacterial and anti-adhesion properties through the electrostatic force and hydrophilic and hydrophobic properties of their surfaces. During the coating deposition process, by adjusting the type of polyelectrolyte, deposition conditions, etc., coatings with different physical and chemical properties and mechanical properties can be prepared to give the coating functionality.

[0003] Polyelectrolytes are commonly used to prepare self-assembled coatings because of their ease of preparation, wide variety and composition, low cost and reusability. However, since the functions and properties of self-assembled coatings prepared from different polyelectrolytes are different, the traditional cooking method requires a lot of time to screen out self-assembled coatings with better performance. At the same time, the shortcomings of manual operation are also exposed, such as: the inability to accurately control the immersion time, operational errors when alternating the immersion of samples, and incorrect number of self-assembled coating layers.

[0004] At the same time, as the alternating immersion proceeds, the polyelectrolyte solution will gradually decrease with the transfer of the sample, so the uniformity of the solution before and after immersion cannot be guaranteed. If manual operation is used, the polyelectrolyte solution will inevitably be contaminated due to improper manual operation. Dust in the air and other drug powders contaminated on the clamping device will also affect the coating performance. Timely rehydration or cleaning will greatly extend the time required to prepare the coating. If a traditional automated robotic arm coating preparation device is used, although the robotic arm avoids the errors caused by manual operation to a great extent, the size of the robotic arm equipment is also a problem that cannot be ignored.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0023] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] The self-assembly coating preparation platform in the present application can accurately locate the positions of each component on the equipment platform through a three-axis truss, and use wide-mouth bottle clamps and carrier clamps to achieve solution preparation and carrier grabbing. At the same time, the barcode scanning camera loaded on the truss module can scan the QR code carried on the carrier, thereby realizing real-time observation and recording of the current state parameters of the sample, and efficiently preparing complex self-assembly coatings of different polyelectrolytes.

[0025] The present invention solves the problems of being unable to control the number of layers and the preparation time in the existing self-assembly coating preparation process and improper operation caused by alternate immersion in a polyelectrolyte solution, avoids errors caused by manual operation, and at the same time ensures that the states of samples in the same batch are the same, thus saving labor costs to a great extent.

[0026] See also Figure 1 , and combined with Figure 2-Figure 15 From the perspective of specific composition, the main structure of the self-assembly coating preparation platform in the present invention includes a shell 10, and the shell 10 is mainly composed of an external frame 11 and an internal equipment platform 12. The external frame 11 is connected as a whole by welding technology, with 45 steel as the frame theme, and the outer shell is wrapped with sheet metal.

[0027] A coating preparation device is installed on the internal equipment platform 12, and the main equipment of the coating preparation device includes: a camera 100, a three-axis truss 20, a nitrogen purge device, a water box assembly 40, a sample carrier assembly 50, a filling assembly 60, a parallel peristaltic pump 70, a drawer 67, a solution barrel 68 and a weighing tray.

[0028] The three-axis truss 20 is fixedly installed above the internal equipment platform 12, and is used to position the water box assembly 40, the sample carrier assembly 50 and the filling assembly 60. Through the close cooperation of the three-axis truss 20, the filling assembly 60, the carrier 90 assembly and the water box assembly 40, self-assembled coatings of different polyelectrolyte solutions can be prepared in sequence, and the nitrogen purge device is used to complete the drying of the sample on the carrier 90.

[0029] The three-axis truss 20 uses a combination of ball linear guides and precision ball screws, and is driven by a servo motor, which can achieve a positioning error of ±0.01mm. While ensuring precision control, it also maximizes space utilization, which can help the self-assembly coating preparation platform realize large-scale industrial automatic production and processing of self-assembly coatings.

[0030] The three-axis truss 20 is connected with an electric gripper 21, a wide-mouth bottle gripper 22 and a carrier gripper 23 for clamping and grasping the wide-mouth bottle 80 and the carrier 90. By precisely manipulating the wide-mouth bottle gripper 22 and the carrier gripper 23 on the three-axis truss 20, especially in the Z-axis module 230, the three-axis truss 20 can minimize the range of motion and the size of the device compared to traditional automated robotic arm coating preparation equipment, thereby achieving both the precision operation of a robotic arm and the simultaneous execution of different tasks.

[0031] The nitrogen purge assembly 30 includes a nitrogen nozzle 31 and a linear module 32. The nitrogen nozzle 31 is connected to the linear module 32 and is used to purge and dry the sample on the carrier 90. When the carrier 90 is placed in the nitrogen purge device, the nozzle assembly can blow out nitrogen to air-dry the sample surface.

[0032] The filling component 60 can be filled with 8 different polyelectrolyte solutions, and the dosage can be accurately controlled by the weighing tray under the solution barrel 68. The Z-axis module 230 of the three-axis truss 20 can grab the wide-mouth bottle 80 and the carrier 90 at the same time, and efficiently complete the solution pouring and the cleaning and drying of the samples on the carrier 90. The entire device can automatically control from designing coating parameters to preparation, and integrate the automated mass production and processing of self-assembly coatings to avoid waste of human resources and errors in manual operations.

[0033] From the perspective of precise positioning through the three-axis truss 20, the three-axis truss 20 includes an X-axis module 210, a Y-axis module 220, a Z-axis module 230 and a drag chain 234. The X-axis module 210 is arranged on both sides of the Y-axis module 220, and the Z-axis module 230 is connected to the Y-axis module 220.

[0034] The X-axis module 210 and the Y-axis module 220 are responsible for locating the two-dimensional position of each component, and the Z-axis module 230 can pour the wide-mouth bottle 80 containing the solution into the water box 41, and can also grab the carrier 90 to perform related operations such as cleaning, drying, and soaking the sample.

[0035] Furthermore, the electric gripper 21, the jar gripper 22 and the carrier gripper 23 are connected to the Z-axis module 230, and the Z-axis module 230 is equipped with a laser rangefinder 24 capable of detecting the lifting height of the Z-axis module 230 and the gripper driven by it and detecting the height of the solution in the water box.

[0036] Specifically, the X-axis module 210, the Y-axis module 220, and the Z-axis module 230 in the three-axis truss 20 are formed to be 1000 mm, 1200 mm, and 300 mm, respectively. The Z-axis module 230 is provided with a module housing. The three-axis truss 20 is fixed above the equipment platform. The X-axis module 210 and the Y-axis module 220 realize two-dimensional positioning of the water box assembly 40, the sample carrier assembly 50, and the filling assembly 60 above the platform. The laser rangefinder 24 realizes the height positioning of the Z-axis module 230, thereby satisfying the three-dimensional positioning of all components of the three-axis truss 20 on the equipment platform.

[0037] The transmission structure of the three-axis truss 20 uses a combination of ball linear guides and precision ball screws, and the drive method uses a servo motor. This combination can achieve a positioning error of ±0.01mm. The three-axis truss 20 also has an emergency avoidance program. During the walking process, the current of the servo motor can be monitored all the time. If a collision occurs and causes an overload, which is generally 1.1 times the rated load, the servo motor will stop running and the servo driver will issue an overload alarm.

[0038] Both sides of the three-axis truss 20 have the limit position of each motion axis, and a limit photoelectric switch is set. When the mechanism touches this limit switch, the servo motor will stop and the servo driver will alarm. The above collision alarm and over-limit alarm are programmed in the PLC program, and the programmer can program and teach the truss manipulator running path and the end manipulator grasping action according to the process requirements, and integrate the external sensor signal and alarm signal into the program.

[0039] From the perspective of accurately grasping the wide-mouth bottle 80 and the carrier 90, the Z-axis module 230 includes a module frame 231, and a left Z-axis module 232 and a right Z-axis module 233 installed on the module frame 231 and connected to the frame through two drag chains 234.

[0040] The electric gripper 21 and the wide-mouth bottle gripper 22 are installed on the left Z-axis module 232, and the carrier gripper 23 is installed on the right Z-axis module 233. The two drag chains 234 on the Z-axis module 230 can respectively realize the wide-mouth bottle gripper 22 and the carrier gripper 23 to grasp the wide-mouth bottle 80 and the carrier 90. The electric gripper 21 tightens the wide-mouth bottle 80 by continuously contracting, and the carrier gripper 23 is installed at the end of the truss, and uses servo electric grippers and contour fingers to clamp the positioning groove of the carrier 90 from the outside.

[0041] A stepper motor 25 is also installed on the left Z-axis module 232 , an electric push rod 26 , a barcode scanning camera 27 , a water pumping needle 28 and a water injection needle 29 are also installed on the right Z-axis module 233 , and a laser rangefinder 24 is fixed under the drag chain 234 .

[0042] After the wide-mouth bottle 80 containing the polyelectrolyte solution is clamped above the water box assembly 40, the stepper motor 25 rotates to pour the solution in the wide-mouth bottle 80 into the water box 41, and the pouring speed and height can be set as needed. After the carrier 90 is clamped, the sample in the carrier 90 needs to be cleaned. The water injection needle 29 above the carrier clamp 23 injects deionized water into the carrier 90 for cleaning the sample surface. The flow rate can be set as needed. The water extraction needle 28 extracts the waste liquid after cleaning into the sewage tank through the peristaltic pump 70, and then the carrier 90 is placed in the nitrogen purge device for drying.

[0043] Since the waste liquid is extracted, the time for nitrogen drying is reduced, which greatly saves the use of nitrogen and reduces the loss of nitrogen.

[0044] After drying, the sample will be clamped and sent into the water box 41 through the electric push rod 26 for coating preparation. The positioning pin 47 in the water box 41 can be tightly combined with the carrier 90 to prevent the carrier 90 from floating due to the large amount of solution in the water box 41. When the soaking time of the carrier 90 in the A solution water box 41 is reached, the truss manipulator takes out the carrier 90, puts it into the clean water box 41 for cleaning, and then puts it into the B solution water box 41. The truss manipulator moves to the A solution water box 41, the water pumping needle 28 descends, and the solution is pumped into the sewage bucket. The water injection needle 29 injects clean water to clean the A water box 41, and the water pumping needle 28 extracts the cleaning water; the water pumping needle 28 rises, the truss manipulator moves to the clean water box 41, the water pumping needle 28 descends, and the clean water for cleaning the carrier 90 is pumped out. After the pumping is completed, the water injection needle 29 injects clean water. The water pumping needle 28 pumps out clean water again, and the water injection needle 29 injects clean water again for standby use.

[0045] After drying, the sample will be clamped and sent into the water box through the electric push rod for the preparation of the self-assembled coating. The positioning pin in the water box can be tightly combined with the carrier, and the float on the side of the water box can detect the solution height through laser ranging, and the water box with a lower liquid level can be replenished. Different water boxes are respectively filled with different types of A and B polyelectrolyte solutions and clean water. The dry sample carrier is first placed in the water box filled with solution A for soaking. The required soaking and cleaning time can be set in the program. After the set time is reached, the Z-axis module will take it out and put it into the clean water box for cleaning. After the cleaning is completed, the carrier gripper will shake it to shake off the residual sewage on the surface of the sample, and then the carrier will be placed in solution B for soaking. After repeating the above steps in solution A, the carrier is sent to the nitrogen purge component for drying, and then a layer of self-assembled coating sample is obtained. If a multi-layer coating sample is required, the number of self-assembled coating layers can be set according to demand.

[0046] After the self-assembly coating sample is prepared, the water extraction needle on the Z-axis module extracts the A and B solutions and clean water into the sewage bucket, and after cleaning the water box through the water injection needle, it is extracted into the sewage bucket through the water extraction needle. After repeating 3 times, a new coating is prepared.

[0047] The barcode scanning camera 27 scans the QR code on each carrier 90 and records the sample status in the program, such as the number of sample coating layers, whether the sample is cleaned, and the polyelectrolyte solution in which the sample is immersed.

[0048] The nitrogen purge assembly 30 includes a nitrogen nozzle 31 and a linear module 32. The nitrogen nozzle 31 is connected to the linear module 32, and the nitrogen bottle is placed in a cabinet on one side of the test bench. When the carrier gripper 23 sends the carrier 90 into the nitrogen purge device, the linear module 32 will translate the nozzle assembly to the rear of the nitrogen purge device according to the program setting. After the carrier 90 is fixed and the Z-axis module 230 rises to a certain height, the linear module 32 translates back to the side of the carrier 90, so that the nozzle assembly is located at the center fixed point directly above it, and the nitrogen purge device starts to operate.

[0049] The nitrogen purge device can dry the residual droplets used for cleaning on the sample surface to ensure the uniformity of the sample during preparation. The nitrogen pressure and height of the nozzle assembly can be adjusted to further increase the drying speed. While the nitrogen purge device is purge-drying, the wide-mouth bottle 80 can be grabbed and dumped simultaneously.

[0050] The filling assembly 60 includes 8 wide-mouth bottles 80, a linkage rod 61, 8 filling needles 62, 8 gooseneck elbows 63, 8 filling sensors 64, a lifting module 65, a filling guide rail 66, a drawer 67, 8 solution barrels 68 and 8 weighing trays 69. The row of peristaltic pumps 70 includes two rows, each row includes multiple peristaltic pumps 70. The filling assembly 60 can place nine different solution reagents at one time, and can record the amount of solution in each wide-mouth bottle 80 according to the weighing tray under the platform.

[0051] The total height of the filling assembly 60 is 462 mm, and the lifting module 65 can drive the filling needle 62 to vertically lift relative to the wide-mouth bottle 80, and the lifting range is 150 mm. The wide-mouth bottle 80 has a total height of 148 mm and a diameter of 86 mm, a bottle mouth height of 30 mm and a diameter of 50 mm, and can be loaded with 500 ml of solution.

[0052] Each row of peristaltic pumps 70 contains four individual peristaltic pumps 70, and the peristaltic pumps 70, solution barrels 68, weighing trays 69, wide-mouth bottles 80, linkage rods 61, filling needles 62, gooseneck elbows 63, and filling sensors 64 correspond to each other and can be controlled independently. The solution barrels 68, wide-mouth bottles 80, filling needles 62, gooseneck elbows 63, and peristaltic pumps 70 are connected by plastic hoses, and each wide-mouth bottle corresponds to the solution barrel located below it.

[0053] Under the tooling of each wide-mouth bottle 80, a filling sensor 64 is set to detect whether there is a filling or not. If the wide-mouth bottle 80 is not put back, an alarm will be sounded. The weighing tray records the weight of the solution barrel 68 in real time, and records the current solution usage in the program background. At the same time, the remaining amount in the solution barrel 68 will be displayed on the touch screen.

[0054] When the lifting module 65 descends, the row peristaltic pump 70 starts to extract the solution in the solution barrel 68, and fills it into the wide-mouth bottle 80 through the gooseneck elbow 63 and the filling needle 62. When the lifting module 65 rises, the solution filling stops. The gooseneck elbow 63 can prevent the solution from being contaminated during the filling process, and a control button is set on the side of the gooseneck elbow 63, which can be used to quickly disassemble the gooseneck elbow 63 and quickly replace the peristaltic pump 70 hose.

[0055] At the same time, the easy-to-disassemble feature of the gooseneck elbow 63 allows the filling component 60 to be immediately repaired when an error occurs during operation. If the hose is directly connected to the filling needle 62, solution residue will remain at the top bend, and the volume and uniformity of the solution in the wide-mouth bottle 80 cannot be guaranteed to be consistent.

[0056] The water box assembly 40 includes 12 water boxes 41, 12 positioning blocks 42, a water box slide rail 43 and a water box tray 44. Each water box 41 is correspondingly provided with a float 45, a water box sensor 46 and a positioning pin 47. The water box sensor 46 is arranged under the water box tray 44 to detect whether there is solution in the water box 41.

[0057] The size of the water box tray 44 is 730*535*15 mm, and the horizontal and vertical spacings between the water boxes 41 are 70 mm and 35 mm respectively. There is a water box sensor 46 under the water box tray 44 to detect whether there is solution or deionized water in the water box 41 to prevent the situation where no water box 41 is filled with water. Each water box 41 can carry a carrier 90.

[0058] The water box tray 44 is fixed by a water box slide rail 43, and the extended length of the water box slide rail 43 is 500 mm. The water boxes 41 of the water box assembly 40 are arranged in three horizontal and four vertical positions, with a size of 172*90*80 mm. When 500 ml of liquid is poured in, the liquid level is 37 mm.

[0059] The float 45 in the water box 41 is used to detect the height of the solution. The laser rangefinder in the Z-axis module feeds back the liquid level to the program and records it, so that the volume of the solution filled in the filling component 60 can be adjusted in subsequent experiments to determine the most suitable liquid level. During the test, deionized water will be automatically injected for flushing each time the liquid is changed. After the test is completed, the water box 41 can be manually removed for thorough cleaning.

[0060] The sample carrier assembly 50 includes a carrier 90 , eight positioning plates 51 , a carrier tray 52 , four carrier sensors 53 , two carrier rails 54 , and one proximity sensor 55 . The carrier tray 52 is mounted on the equipment platform via the two carrier rails 54 .

[0061] The carrier sensor 53 and the proximity sensor 55 are disposed below the carrier tray 52 , wherein the carrier sensor 53 is used to detect whether a carrier 90 is mounted on the carrier tray 52 , and the proximity sensor 55 is used to detect whether the carrier tray 52 is on the tray station.

[0062] The size of the carrier tray 52 is 460*360*10 mm, and the carriers 90 are grouped into 4 trays. There are also 4 carrier sensors 53 installed under the carrier tray 52 to detect whether there are carriers 90 on it. The proximity sensor 55 equipped under the tray is used to detect whether the tray is in a specific position.

[0063] The lower carrier rail 54 extends 450 mm. The size of the carrier 90 is 140*76*30, and each carrier 90 can carry 25 samples of 10 mm*10 mm*3 mm. The carrier 90 is equipped with a QR code, and the code scanning camera 27 in the Z-axis module 230 on the three-axis truss 20 can scan the QR code to record the current status of each carrier 90. The QR code content is the carrier 90 number, which is used together with the code scanning mechanism on the truss manipulator to automatically identify the carrier 90 number and bind the test data, such as: the immersed polyelectrolyte solution, the current number of self-assembled coating layers, the sample cleaning status, etc.

[0064] The positioning plate 51 with four carrier sensors 53 is used to place the uncoated carrier 90. The four detection switches below and the test settings form a closed loop to detect whether the carrier 90 exists before the test. If it exists, the test is performed. The positioning plate 51 without the carrier sensor 53 is used to place the carrier 90 that has been tested. It is not placed by default at the beginning of the test.

[0065] To prevent the carrier 90 from being placed accidentally, the laser distance sensor on the Z-axis module 230 will detect the height information of the carrier 90 module position before starting the test to confirm whether there is a carrier 90 and the number of carriers 90 layers to prevent collisions caused by misplacement. The carrier tray 52 is fixed with a carrier rail 54 to facilitate the operator to place the carrier 90. In order to prevent the operator from not pushing the carrier tray 52 back to the specified position, a proximity sensor 55 is installed below. Only when the carrier tray 52 is pushed back to the specified position, the proximity sensor 55 will have a signal to ensure the normal operation of the test.

[0066] Four manually opened and closed cabinet doors 13 are installed at the lower ends of the front and back sides of the shell 10, and electric lifting glass doors 14 are installed at the upper ends. The lifting doors are driven by electric cylinders and guide rails. The electric cylinders of the lifting glass doors 14 on the front and rear sides of the shell 10 are installed on the left side of the equipment and wrapped with an outer shell.

[0067] The electric lifting glass door 14 is installed on the front and rear sides of the housing 10 for easy display, adjustment and maintenance. Four exhaust vents are set on the top plate of the housing 10, and cooling fans are installed on the exhaust vents to speed up the circulation of air inside the housing 10 to ensure that the interior will not overheat due to equipment operation problems. Four casters are installed at the bottom of the housing 10 for easy overall movement.

[0068] The camera 100 is located at the top of the platform and is used to monitor the operation of each component on the device platform. A light strip surrounds the top of the device. If a component reports an error during operation, a red light will be on, and a green light will be on when it is operating normally.

[0069] Compared with the prior art, the self-assembly coating preparation platform of the present invention has the following advantages: It is possible to complete the self-assembled coatings prepared by different polyelectrolyte solutions at the same time, and the required coatings can be customized according to the program, reducing the time consumed in the screening of high-performance functional self-assembled coatings; The filling assembly 60 ensures that the solution is not contaminated by dust in the external environment, and the gooseneck elbow 63 is easy to disassemble so that it can be replaced in time when the program runs with an error, thereby ensuring the uniformity of the solution; The three-axis truss 20 is used to accurately control the time required for preparation, and program control is used to avoid operational errors caused by manual operation. The number of layers and thickness of the self-assembled coating can be effectively controlled. At the same time, a fixed nitrogen purge device can be used to ensure the consistency of the coating state on the sample, which greatly speeds up the preparation speed of the coating.

[0070] The QR code on the carrier 90 can be scanned by the barcode scanning camera 27 to record parameters such as the name of the solution in which the current sample is immersed, the type of solution, and the number of coating layers, and the current progress can be observed in real time on the touch panel.

[0071] By adding other components to the platform to achieve integrated preparation and characterization, the characterization results of different high-performance functional self-assembled coatings prepared can be directly obtained, and the preparation plan and parameters can be adjusted according to the characterization results.

[0072] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0073] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
