The liquid marble is a micro-reactor formed by wrapping liquid drops with hydrophobic particles, has the characteristics of small friction force, small pollution, convenient transfer and the like, and has wide application prospects in biology, chemistry and medicine. At present, the preparation methods of liquid marbles are various, the traditional preparation method of the liquid marbles is mainly based on manual operation, powder is adhered to liquid drops through manual oscillation, however, in the traditional preparation method, the manual oscillation is difficult to accurately control, the obtained liquid marbles are good in usability, the manual preparation time cost is high, and high yield is difficult to realize. The automatic preparation platform is used for sucking liquid drops with different volumes to the vibration platform by controlling an electric field and completing the preparation of liquid marbles under the oscillation of the vibration platform, so that the yield is improved to a certain extent, but the method has high requirements on equipment and complex operation, and is difficult to widely apply. Meanwhile, the electric field is introduced in the preparation process, so that the prepared liquid marble can be influenced by the electric field, and the application is limited to a certain extent.
The preparation process of the liquid marble mainly comprises a liquid injection process, a powder spraying process and an oscillation process. In order to realize the automatic operation of the procedures, unlike the existing process that the positions of the porous plates are kept still, the liquid injection module and the powder injection module are moved and the liquid marble preparation process is completed through the oscillating table, the porous plates are circularly conveyed to the liquid injection station and the powder injection station, bare liquid drops are dripped on the porous plates at the liquid injection station, the bare liquid drops on the porous plates are subjected to powder injection at the powder injection station to complete the preliminary preparation of the liquid marble, and the porous plates are directly oscillated on the porous plate fixture at the oscillating station to complete the complete package of surface powder on the liquid marble. The automatic preparation of the liquid marble is realized, and the preparation device has simple structure and convenient use.
First embodiment:
as shown in fig. 1, an automatic liquid marble preparation device based on a rotary positioning structure of the present embodiment mainly includes: a rotating structure 100 and a perforated plate loading and unloading structure 300. The rotating structure 100 includes a fixed column 110 fixed to a table and a rotating table 120 mounted on the top of the fixed column 110, as shown in fig. 2. The rotary table 120 in this embodiment is a rotary table capable of being automatically positioned. Specifically, a plurality of female taper grooves 121 are provided on the bottom surface of the turntable 120 in the circumferential direction, and a plurality of clippers 123 are provided on the base 122 of the turntable 120. The number of the female cone grooves 121 and the number of the clippers 123 are correspondingly set according to specific positioning positions and precision. If 12 female taper grooves 121 are provided, the corresponding accuracy is 30 °. The front end of the clipper 123 is provided with a male frustum 124 matched with the female taper groove 121. The pusher 123 is provided with a motor, and the male frustum 124 can push out the extrusion female taper groove 121 along the axial direction of the male frustum so as to drive the rotary table 120 to rotate. When the rotary table 120 needs to be positioned, the male frustum 124 at the front end of the push-out body 123 is completely pushed out, a limit fit is formed between the male frustum 124 and the female taper groove 121, and at the moment, the female taper groove 121 and the male frustum 124 are abutted to enable the rotary table 120 to be unable to rotate, so that hovering of the rotary table 120 is achieved. By changing the number of the female taper grooves 121 and the clippers 123 provided in the circumferential direction, the hovering position of the turntable 120 can be changed.
It should be noted that, the specific mechanism for driving the rotary table 120 to rotate and hover is not limited, and a bearing may be installed at the top end of the fixing column 110 in an interference manner, the bearing may be connected to the rotary table 120, and a motor and a transmission device may be installed, and the motor drives the transmission device to rotate and hover the rotary table 120.
In order to realize the rotation of the rotary table 120 and simultaneously convey liquid marbles between different stations, in this embodiment, the rotary table 120 has a disk shape, and four perforated plate holders 200 are fixed to the circumferential side wall of the rotary table 120 at intervals. As shown in fig. 3, the perforated plate fixture 200 includes a fixture body 210 and a connection part 220, the fixture body 210 is a box-shaped structure with an open top, the connection part 220 is a long rod connected to one side of the fixture body 210, and a free end thereof is arc-shaped for being matched with a side wall of the rotary table 120 to fix the perforated plate fixture 200 on the rotary table 120.
A clamping portion 230 for coupling with the porous plate 400 is provided on each of the clamp bodies 210, and loading and unloading of the porous plate 400 is achieved by the clamping portion 230. In this embodiment, one sidewall of the fixture body 210 extends outwards to form a baffle 240, and two flanges 250 are disposed opposite to each other in a direction perpendicular to the baffle 240, and a space between the baffle 240 and the two flanges 250 forms a clamping portion 230 for accommodating the porous plate 400. Alternatively, the specific shape and size of the clamping portion 230 may be changed accordingly depending on the size of the porous plate 400.
Further, in this embodiment, the top end of the flange 250 is arc-shaped, and the height of the side adjacent to the baffle 240 is greater than the height of the side away from the baffle 240, and the arc-shaped design is based on the circular motion track of the porous plate loading and unloading structure, so that no collision occurs when loading or separating from the porous plate 400, and the loading or separating from the porous plate 400 can be more convenient.
In order to completely wrap the surface powder around the liquid marble, the present embodiment further provides an oscillating member 260 in the jig body 210, and the flange 250 is reciprocated left and right by the oscillating member 260, thereby oscillating the perforated plate 400 in the loading nip 230. When the powder spraying process is completed on the bare droplets on the porous plate 400, the preliminary coating of the powder is completed, and the powder coating of the liquid marble can be more fully performed by shaking, i.e., the porous plate is shaken left and right to complete the complete coating of the surface powder. Specifically, the fixture body 210 is internally provided with a linear guide rail 270 and a motor, the linear guide rail 270 is provided with a rack, and the output end of the motor is connected to the gear 280 and meshed with the rack on the linear guide rail 270, so as to drive the linear guide rail 270 to reciprocate left and right. Two struts 290 are fixed on the linear guide 270, and the other ends of the struts 290 are fixedly connected with the flange 250. Therefore, the linear guide 270 can move left and right while reciprocating left and right, thereby oscillating the perforated plate.
The present invention also designs a perforated plate loading and unloading structure 300 as shown in fig. 4 for achieving automatic loading and unloading of the perforated plate 400, i.e., automatic loading of the perforated plate 400 on the structure on the perforated plate holder 200 or detachment of the perforated plate 400 from the perforated plate holder 200 to the structure. Specifically, the perforated plate loading and unloading structure 300 includes a supporting base 310 for fixing, and a connecting rod 320 is provided at the top of the supporting base 310, and the connecting rod 320 can rotate around the top of the supporting base 310 in a vertical plane, similar to a ferris wheel. The end of the connecting rod 320 is fixedly provided with a U-shaped engaging portion 330 for clamping the porous plate, the porous plate is loaded or separated by the engaging portion 330, and the specific shape of the engaging portion 330 may be changed according to the shape of the porous plate 400.
In this embodiment, four links 320 are provided on the perforated plate attaching/detaching structure 300, and each link 320 is provided with an engaging portion 330, and the opening of the engaging portion 330 is directed to the right. Taking the link 320 as an example, when the link 320 is used, the link 320 is rotated counterclockwise first to load the porous plate 400 onto the porous plate holder 200, the structure 100 is rotated such that another porous plate holder reaches the loading and unloading position, the link 320 is rotated counterclockwise continuously to load the second porous plate 400 onto the porous plate holder 200, the process is repeated until the last porous plate holder 200 in the idle state reaches the loading and unloading position, and the last porous plate 400 on the link 320 is loaded onto the porous plate holder 200 in the idle state. The rotating structure 100 is then operated again, at which time the first loaded porous plate 400 has been moved one round to complete the preparation of the liquid marble back to the loading position, and at which time the completely unloaded porous plate loading structure 300 starts to rotate clockwise to unload the first porous plate 400 on the engaging portion 330, which has completed the preparation process of the liquid marble, and the three subsequent porous plates are also successively unloaded and collected by the porous plate loading structure 300 following this step.
Alternatively, a greater number of links 320 may be provided, distributed in a spoke-like manner in the vertical plane, each of which is provided with a snap-in portion 330, and a corresponding increased number of docking stations are provided on the rotating structure, thereby improving the yield of liquid marbles per unit time.
In order to prevent the porous plate carrying the prepared liquid marble from tilting as the link 320 rotates so that the liquid marble rolls out, the present embodiment provides a horizontal holding mechanism on the porous plate loading and unloading structure 300, which enables the porous plate 400 on the engaging portion 330 to be always maintained in a horizontal state as the link 320 rotates. Specifically, as shown in fig. 5 and 6, the horizontal holding mechanism includes a first gear shaft 340 disposed at the top of the support base 310, a second gear shaft 350 disposed inside the connecting rod 320, the first gear shaft 340 and the second gear shaft 350 rotatably connected through a bevel gear, a third gear shaft 360 disposed at the end of the connecting rod 320, and a locking portion 330 mounted on the third gear shaft 360. The third gear shaft 360 is rotatably connected with the second gear shaft 350 through a bevel gear. And the transmission ratio between the first gear shaft 340 and the second gear shaft 350 is 1:2, and the transmission ratio between the second gear shaft 350 and the third gear shaft 360 is 2:1.
After the motor drives the first gear shaft 340 at the top of the supporting seat 310 to rotate, the second gear shaft 350 is driven to rotate through the bevel gear rotating connection, and then the third gear shaft 360 is driven to rotate through the bevel gear rotating connection, so as to drive the clamping portion 330 to rotate. Because the transmission ratio between the first gear shaft 340 and the second gear shaft 350 is 1:2, and the transmission ratio between the second gear shaft 350 and the third gear shaft 360 is 2:1, it is ensured that the connecting rod 320 rotates once, and the engaging portion 330 rotates once in the opposite direction, so that the engaging portion 330 always keeps horizontal running.
Further, in order to facilitate the installation of the liquid injection module and the powder injection module, two fixing rods 130 are fixedly installed on the chassis of the rotating structure 100, and the installation table 140 for installing the liquid injection module 500 and the installation table 140 for installing the powder injection module 600 are fixedly installed at the top ends of the two fixing rods 130, respectively. It should be noted that, the specific structure of the mounting table 140 is not limited, and the shapes and dimensions of the liquid injection module 500 and the powder injection module 600 may be designed according to the structures for mounting the liquid injection module and the powder injection module on the existing production line.
