Description

Technical Field

[0001] The present invention relates to the field of silicone gel preparation, and particularly to a silicone gel preparation device and method for robot skin. Background Art

[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. Among them, the robot skin not only improves the appearance and function of the robot, but also enhances its interaction ability with the environment and humans. With the progress of technology, robots have begun to be widely used in multiple industries. Silicone gel is a semi-solid material formed by organosilicon compounds (such as polydimethylsiloxane), with both solid and liquid characteristics. As a flexible substrate material for robot skin, silicone gel has good flexibility, elasticity and biocompatibility, and can bend, stretch and twist like human skin, providing soft and stable support for components such as sensors and circuits in the robot skin.

[0003] In the production and processing of silicone gel, a preparation device is needed to filter the silicone gel raw materials, so as to reduce the influence of impurities in the raw materials on the performance of the silicone gel. When using a filtering device to filter the raw materials, most of the raw materials mainly fall through the filter screen by gravity after being placed on the filter screen, and the filtering efficiency of this filtering method is relatively low.

[0018] A process for a silicone gel preparation device for a robot skin includes the following steps:

[0019] S1. First, the staff can take out filter screens of different specifications as needed, and place the filter screens with the filter hole specifications from large to small corresponding to the height of the processing cylinder in sequence according to the filter hole specifications of the filter screens and the height of the processing cylinder. After the placement of the filter screens is completed, the driving cylinder can be controlled to drive the limiting rods to move until the limiting rods are inserted into the limiting holes to complete the limitation of the filter screens.

[0020] S2. Add the raw materials required for the production of silicone gel into the processing cylinder through the feeding hopper, and then close the valve.

[0021] S3. Start the driving motor in the pressurizing assembly to drive the elliptical cam to squeeze the linkage plate and the pressurizing airbag, so as to realize the injection of air and pressurization inside the processing cylinder, so that the raw materials always have the driving force to move downward, and further improve the filtering efficiency of the raw materials.

[0022] S4. During the rotation of the drive motor, the stirring frame inside the processing cylinder can also be driven by a belt and a rotating rod to stir and mix the raw materials, so that the raw materials are more evenly dispersed on the filter screen, thereby improving the filtering effect on the raw materials;

[0023] S5. After filtration, the blanking sealing piece can be opened to make the filtered raw materials fall from the blanking port into the aggregate frame, and thus the filtration and preparation of the raw materials required for silicone gel can be completed;

[0024] S6. After discharging the raw materials, first make the inclined platform contract, then control the rotating motor to drive the supporting frame and the filter screen inside to turn over, and then the collection frame can be inserted into the processing cylinder and the sealing door can be opened, so that it is convenient for the staff to use a brush to scrape and clean the raw materials stuck in the filter screen.

[0025] Compared with the related technology, the silicone gel preparation device and process for robot skin provided by the present invention have the following beneficial effects:

[0026] 1. Through the setting of the pressurization component in the present invention, during the preparation process, after adding the required raw materials into the processing cylinder, the pressurization component can pressurize the inside of the processing cylinder, so that the raw materials above the filter screen have a downward acting force in addition to gravity. Therefore, the falling and filtering of the raw materials can be made more convenient, thereby assisting in improving the filtering efficiency of the device.

[0027] 2. During the operation of the pressurization component in the present invention, the stirring blades can also be driven to rotate inside the processing cylinder, making the raw materials above the filter screen more evenly dispersed, thereby reducing the phenomenon that the raw materials in this area accumulate due to the blockage of some filter holes in the filter screen. Therefore, it can assist in improving the filtering effect of the filter screen.

[0028] 3. Through the movable installation of the filter screen in the present invention, after the filtration of the raw materials is completed, the filter screen can be rotated and turned over, making the blocked side of the filter screen face downward, then the sealing door can be opened, and a brush can be used to scrape the filter screen, so that the raw materials blocked inside the filter screen can fall from the filter screen, thus facilitating the staff to clean the filter screen in the reverse direction.

[0029] 4. In the present invention, the filter screen is fixed by means of clamping. During the subsequent use process, by driving the working of the driving cylinder to drive the limiting rod to slide out of the limiting hole, after releasing the limitation on the filter screen, the filter screen can be quickly taken out from the processing cylinder, so as to flexibly disassemble and replace the filter screen according to the raw material specifications. Therefore, the flexibility of the device can be improved. Description of the Drawings

Detailed implementation mode

[0041] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0043] Please refer to Figures 1 to 10 , a silicone gel preparation device for robot skin provided by an embodiment of the present invention, the silicone gel preparation device for robot skin includes a frame 1 and a processing cylinder 2 for filtering silicone gel raw materials.

[0044] In an embodiment of the present invention, please refer to Figures 1 to 10, a plurality of processing cylinders 2 are provided and are installed in the frame body 1 in a stepped manner in sequence. A filter net 4 is movably installed inside the processing cylinder 2, and a pressurization assembly 3 for increasing the falling speed of the raw materials is provided outside the processing cylinder 2; the pressurization assembly 3 includes a pressurization airbag 314 and a cam 322 for extruding the pressurization airbag 314. The pressurization airbag 314 is arranged on the outer wall of the processing cylinder 2, and the cam 322 is arranged on one side of the pressurization airbag 314 outside the processing cylinder 2. An air inlet pipe 315 and an exhaust pipe 316 which are communicated are inserted inside the pressurization airbag 314. One-way valves are provided on both the air inlet pipe 315 and the exhaust pipe 316. A connecting hose 317 is provided at the end of the exhaust pipe 316. One end of the connecting hose 317 away from the exhaust pipe 316 is provided with a communicated air guide pipe 34, and the air guide pipe 34 is communicated with the inner top of each processing cylinder 2; the pressurization assembly 3 further includes a support plate 31 and a fixing frame 32. The support plate 31 is arranged on the outer wall of the processing cylinder 2. The outer wall of the support plate 31 is fixedly connected with one side wall of the pressurization airbag 314. Guide rods 311 are provided at the four corners of the outer wall of the support plate 31. A linkage plate 313 which is slidably connected is sleeved outside the guide rods 311. One side wall of the linkage plate 313 is fixedly connected with the pressurization airbag 314. The other side of the linkage plate 313 abuts against and is slidably connected with the cam 322. A spring 312 is sleeved on the outer wall of the guide rod 311. Both ends of the spring 312 are fixedly connected with the corresponding support plate 31 and the linkage plate 313, and the cam 322 is of an elliptical structure; a driving rod 321 which is rotatably connected is installed inside the fixing frame 32. The outer wall of the driving rod 321 is fixedly connected with the inner wall of the cam 322. A driving motor 323 is provided at one end of the driving rod 321, and the driving motor 323 is connected with the inner wall of the fixing frame 32. The pressurization assembly 3 further includes a support frame 33. The support frame 33 is fixedly arranged on the processing cylinder 2. Rotating rods 331 which are rotatably connected are provided at the positions corresponding to the centers of each processing cylinder 2 at the inner top of the support frame 33. A belt 332 is installed between adjacent two rotating rods 331. A belt 332 is also installed between the rotating rod 331 close to the driving rod 321 and the driving rod 321. The bottom ends of the rotating rods 331 all extend into the corresponding processing cylinder 2 and are rotatably connected with the processing cylinder 2. The pressurization assembly 3 further includes a support frame 35. A rotating piece 351 which is rotatably connected is provided inside the support frame 35. The top of the rotating piece 351 is fixedly connected with the bottom end of the rotating rod 331. An electric push rod 36 is provided at the bottom of the rotating piece 351, and a stirring frame 361 is provided at the bottom end of the electric push rod 36.

[0045] It should be noted that during the use process, when the driving motor 323 drives the driving rod 321 to rotate, the elliptical cam 322 located on the outer wall of the driving rod 321 will squeeze the linkage plate 313. According to the characteristics of the elliptical structure, the rotating cam 322 will squeeze the linkage plate 313 with different depths. When the elliptical cam 322 rotates from the relatively longer side to the relatively shorter side, the spring 312 located on the outer wall of the guide rod 311 will squeeze the linkage plate 313 through its own acting force, so that the linkage plate 313 can move for reset. During the reset process of the linkage plate 313, the supercharging airbag 314 will inhale the outside air through the air inlet. Thus, when the elliptical cam 322 squeezes the linkage plate 313 again, the gas in the supercharging airbag 314 can be squeezed out again, so as to realize the cyclic squeezing operation of the supercharging airbag 314;

[0046] The gas discharged from the supercharging airbag 314 is introduced into the corresponding treatment cylinder 2 one by one through the air guide pipe 34, so that there is a gas flowing from top to bottom inside each treatment cylinder 2. Therefore, when the filter screen 4 filters the raw materials, the raw materials can always have a downward acting force in addition to gravity, which can make the falling and filtering of the raw materials more convenient, and thus can assist in improving the filtering efficiency of the device.

[0047] It should also be noted that while the driving rod 321 is rotating, the driving rod 321 can also drive the rotating rod 331 to rotate synchronously through the belt 332. At this time, the rotating rotating rod 331 will drive the corresponding stirring frame 361 below to rotate through the rotating piece 351, so as to realize the stirring and mixing of the raw materials inside the treatment cylinder 2, making the raw materials more evenly dispersed inside the treatment cylinder 2. Furthermore, during the filtering process, when some filter holes inside the filter screen 4 are blocked, the phenomenon of raw material accumulation in this area can be reduced. Therefore, the filtering efficiency of the device can be improved, and through the multi-stage filtering of the raw materials, the raw materials can be discharged outward in a more refined state, so that the raw materials used for preparing the silicone gel can be more pure. This can not only reduce the probability of defects such as bubbles and spots on the surface of the silicone gel caused by impurities, but also reduce the probability of impurities in the robot skin prepared from the silicone gel interfering with the sensitivity or signal transmission of the sensors in the robot;

[0048] At the same time, through the setting of the connecting hose 317, when the supercharging airbag 314 performs the compression and expansion cyclic operation, it can drive the connecting hose 317 to move synchronously. Furthermore, while the exhaust pipe 316 and the air guide pipe 34 are always kept in a connected state, it will not hinder the movement of the supercharging airbag 314;

[0049] Among them, the one-way valves on the intake pipe 315 and the exhaust pipe 316 can ensure that the air compressed and discharged by the pressurizing airbag 314 is always conveyed from the exhaust pipe 316 to the external connecting hose 317 and the air guide pipe 34. When the pressurizing airbag 314 expands, it can always suck in external air through the intake pipe 315, avoiding the phenomenon of gas backflow in the air guide pipe 34.

[0050] In an embodiment of the present invention, please refer to Figures 1 to 10 , a supporting component 5 is provided below the stirring frame 361 inside the processing cylinder 2. The supporting component 5 includes a supporting frame 51. The supporting frame 51 is of a rectangular structure. The relatively shorter side walls of the rectangular supporting frame 51 are rotatably connected to the inner wall of the processing cylinder 2. A rotating motor 53 is provided on one of the relatively shorter side walls of the supporting frame 51. The rotating motor 53 is located outside the processing cylinder 2. A cushion frame 511 is provided inside the supporting frame 51. The inner wall of the supporting frame 51 abuts against and is slidably connected to the outer wall of the filter screen 4. The bottom of the filter screen 4 abuts against the bottom of the cushion frame 511. And a sealing door 222 is provided on the outer wall of the processing cylinder 2 above the supporting component 5. Transfer frames 54 are provided on both of the relatively longer side walls of the supporting frame 51. Symmetrically distributed supporting cylinders 541 are provided on the outer wall of the transfer frame 54. An inclined platform 52 fixedly connected together is provided at the end of the supporting cylinders 541 on the outer wall of the same transfer frame 54. Both ends of the inclined platform 52 abut against and are slidably connected to the inner wall of the processing cylinder 2. And the inner wall of the inclined platform 52 abuts against and is slidably connected to the top and bottom of the supporting frame 51. A driving cylinder 542 is provided inside the transfer frame 54. A sliding frame 543 connected in a sliding manner is inserted inside the transfer frame 54. The side wall of the sliding frame 543 is fixedly connected to the end of the driving cylinder 542. Symmetrically distributed limiting rods 544 are provided on the side of the sliding frame 543 away from the driving cylinder 542. The ends of the limiting rods 544 are inserted into the supporting frame 51. And the outer wall of the limiting rods 544 abuts against and is slidably connected to the inner wall of the supporting frame 51. Limiting holes 41 are provided at the relative positions of the side wall of the filter screen 4 and the limiting rods 544. And the inner wall of the limiting holes 41 abuts against the outer wall of the limiting rods 544.

[0051] It should be noted that: by providing the cushion frame 511 inside the supporting frame 51, when installing the filter screen 4, the cushion frame 511 can support the placed filter screen 4, enabling the filter screen 4 to be installed and placed more accurately and quickly. Then, the driving cylinder 542 can be controlled to drive the sliding frame 543 and the limiting rods 544 outside it to move. When the limiting rods 544 penetrate through the supporting frame 51 and are inserted into the limiting holes 41 on the side wall of the filter screen 4, the fixed installation of the filter screen 4 can be achieved;

[0052] It should also be noted that through the setting of the support cylinder 541, when the staff needs to turn over the filter screen 4, the support cylinder 541 can be controlled to contract first. The contracted support cylinder 541 will drive the inclined platform 52 to move towards the direction close to the supporting frame 51, so as to reduce the distance between the side wall of the inclined platform 52 and the side wall of the treatment cylinder 2. Then, when the rotation motor 53 works later, it can smoothly drive the supporting frame 51, the filter screen 4 and the external inclined platform 52 to rotate, thus avoiding the phenomenon that the side wall of the inclined platform 52 abuts against the inner wall of the treatment cylinder 2 during the rotation process and hindering the rotation of the supporting frame 51. Therefore, the filter screen 4 can be turned over smoothly;

[0053] And through the setting of the sealing door 222, when the sealing door 222 is opened, it is convenient for personnel to put their palms into the treatment cylinder 2 and use a brush to scrape and clean the back of the filter screen 4;

[0054] At the same time, through the setting of the inclined platform 52, when filtering raw materials, the outer wall of the inclined platform 52 can make the raw materials located on its outer wall have a tendency to slide down, so that the raw materials can slide down smoothly above the filter screen 4 for filtering. At the same time, a rubber sheet is provided on the inner wall of the inclined platform 52, and the rubber sheet can make the sealing between the inclined platform 52 and the parts where it abuts against the supporting frame 51 and the inner wall of the treatment cylinder 2 more excellent, so as to avoid the phenomenon that the raw materials fall from the area outside the filter screen 4;

[0055] Furthermore, the rotation motor 53 used to control the rotation of the supporting frame 51 is a self-locking motor. Therefore, after the rotation motor 53 adjusts the supporting frame 51 to the horizontal state, it can avoid the phenomenon that the supporting frame 51 rotates randomly during the supporting process.

[0056] In the embodiment of the present invention, please refer to Figures 1 to 10 , a controller 11 is provided on the side wall of the frame body 1, and a collecting frame 12 is provided below the treatment cylinder 2 inside the frame body 1. A feeding hopper 7 is provided at the top of the treatment cylinder 2 on the side with a higher position and is communicated with it. A valve 71 is provided on the feeding hopper 7. The inner bottom of the treatment cylinder 2 is of an inclined surface structure. Adjacent two treatment cylinders 2 are communicated with each other. A discharge port 23 is opened on the side wall of the treatment cylinder 2 on the side with a lower position. Convex rods 24 are provided on both sides of the discharge port 23 on the outer wall of the treatment cylinder 2. A discharge sealing piece 25 is sleeved on the outer wall of the convex rod 24 and fixed by a nut. A pressure relief valve 26 is provided on the treatment cylinder 2. An installation groove 22 is opened on the side wall of the treatment cylinder 2. A slot 21 is opened at the position of the inner wall of the treatment cylinder 2 opposite to the installation groove 22. A sealing baffle 221 fixedly connected by bolts is provided at the position of the outer wall of the treatment cylinder 2 opposite to the installation groove 22. A collecting frame 6 connected in a sliding manner is inserted into the treatment cylinder 2. The collecting frame 6 is fixedly connected to the outer wall of the treatment cylinder 2 by bolts. Insertion strips 61 are provided on both side walls of the collecting frame 6, and the outer wall of the insertion strip 61 abuts against and is slidably connected to the inner wall of the slot 21.

[0057] It should be noted that: by setting a valve 71 on the feeding hopper 7, after the addition of the silicone gel raw material is completed, by closing the valve 71, the treatment cylinder 2 can be in a sealed state, so that the working efficiency of the pressurizing assembly 3 can be more excellent;

[0058] And through the setting of the pressure relief valve 26, as the pressurizing assembly 3 continues to perform pressurization operations, when the pressure inside the treatment pipe reaches the set value, the pressure relief operation can be automatically carried out, thus avoiding the phenomenon that the pressurizing airbag 314 is damaged due to excessive pressure;

[0059] It also should be noted that: by setting the inner bottom of the treatment cylinder 2 as an inclined surface structure, and setting the connecting part of two adjacent treatment cylinders 2 at the bottom end of the inclined surface of the treatment cylinder 2 at a higher position, the filtered raw material inside the treatment cylinder 2 can flow more smoothly towards the lower side, and at the same time, the discharging of the raw material after filtration can be more convenient.

[0060] A process for a silicone gel preparation device for robot skin includes the following steps:

[0061] S1. First, the staff can take out different specifications of filter meshes 4 as needed, and place the filter meshes 4 with gradually decreasing filter specifications corresponding to the height of the treatment cylinder 2 in sequence according to the filter hole specifications of the filter meshes 4 and the height of the treatment cylinder 2. After the placement of the filter meshes 4 is completed, the driving cylinder 542 can be controlled to drive the limiting rod 544 to move until the limiting rod 544 is inserted into the limiting hole 41 to complete the limitation of the filter meshes 4;

[0062] S2. Add the raw materials required for silicone gel production into the treatment cylinder 2 through the feeding hopper 7, and then close the valve 71;

[0063] S3. Start the driving motor 323 in the pressurizing assembly 3 to drive the elliptical cam 322 to squeeze the linkage plate 313 and the pressurizing airbag 314, thereby realizing the injection of air and pressurization inside the treatment cylinder 2, so that the raw materials always have the driving force to move downward, and further improving the filtration efficiency of the raw materials;

[0064] S4. During the rotation of the driving motor 323, the stirring frame 361 located inside the treatment cylinder 2 can also be driven by the belt 332 and the rotating rod 331 to stir and mix the raw materials, so that the raw materials are more evenly dispersed on the filter meshes 4, thereby improving the filtration effect of the raw materials;

[0065] S5. After filtration, the blanking sealing piece 25 can be opened to make the filtered raw materials fall from the blanking port 23 into the aggregate frame 12, and thus the filtration and preparation of the raw materials required for silicone gel can be completed;
