Detailed implementation manners

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, 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.

[0033] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0034] Please refer to Figures 1 to 7The embodiment of the present invention provides a modified solid-phase silicone gel preparation device and process for robot skin. The modified solid-phase silicone gel preparation device for robot skin includes: a support frame 1, and a reaction kettle 2 and a temperature control tube 3 mounted on the support frame 1, and the temperature control tube 3 is located below the reaction kettle 2;

[0035] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , also includes:

[0036] The conduit 4 is installed at the bottom end of the reactor 2, and the end of the conduit 4 away from the reactor 2 is inserted into the temperature control tube 3 and installed with a liquid guide plate 41. Two groups of liquid guide plates 41 are provided, and are symmetrically distributed based on the conduit 4. The middle parts of the two groups of liquid guide plates 41 are provided with a glue outlet hole 401, and the glue outlet hole 401 is connected to a gel pump 5. The liquid outlet end of the gel pump 5 is connected to a centrifugal liquid guide mechanism 6 for shaking and exhausting the silicone gel. A gate member 7 for sealing the conduit 4 and the reactor 2 is installed in the conduit 4;

[0037] The sealing cover 8 is installed on the reaction kettle 2, and a stirring mechanism 9 for stirring the raw materials for preparing the silica gel is installed on the sealing cover 8.

[0038] It should be noted that: when in use, the raw materials for preparing the modified silicone gel are introduced into the reactor 2 one by one, and then the stirring mechanism 9 on the sealing cover 8 is started to fully stir the raw materials introduced into the reactor 2 to obtain liquid modified silicone gel. After the stirring is completed, the conduit 4 is opened by the gate member 7, so that the stirred liquid silicone gel is introduced into the conduit 4, and then the gel pump 5 is started to suck the liquid silicone gel in the conduit 4 into the centrifugal liquid guiding mechanism 6 through the gel outlet hole 401, and then the centrifugal liquid guiding mechanism 6 is used to centrifugally discharge the bubbles in the introduced liquid modified silicone gel, so as to improve the quality of its liquid extrusion, so as to improve the quality of the solid modified silicone gel.

[0039] In this embodiment, the gate member 7 includes hydraulic rods 71. There are two groups of hydraulic rods 71, and the two groups of hydraulic rods 71 are fixedly installed on the temperature control pipe 3. The output ends of the two groups of hydraulic rods 71 are jointly fixedly installed with a sealing gate 72 for sealing the conduit 4. The outer side wall of the sealing gate 72 is slidably matched with the inner side wall of the conduit 4, and a groove is formed on the outer side wall of the sealing gate 72. A sealing ring 73 is embedded in the groove. When the gate member 7 is in use, when it is necessary to seal the conduit 4 and the reaction kettle 2, the hydraulic rod 71 is controlled to drive the sealing gate 72 to slide upward to the top of the conduit 4, so as to prevent the raw materials in the reaction kettle 2 from being prematurely introduced into the conduit 4, which affects normal stirring. After the stirring is completed, when it is necessary to open the glue outlet hole 401, the hydraulic rod 71 is started to drive the sealing gate 72 to slide downward until it slides below the glue outlet hole 401, so as to open the glue outlet hole 401, so that the modified silicone gel in the reaction kettle 2 is introduced into the conduit 4 and exported from the glue outlet hole 401. The sealing gate 72 uses the sealing ring 73 to seal the gap between the conduit 4 and the sealing gate 72, to prevent the liquid silicone gel from leaking from the conduit 4.

[0040] Further, in order to facilitate the addition of the solid-phase modified silicone gel raw materials, two feeding pipes 21 are installed at the top of the reaction kettle 2. The two feeding pipes 21 are symmetrically distributed based on the reaction kettle 2 and are both fixedly installed with control valves 22. This can be used to classify and put the solid raw materials and liquid raw materials through the two feeding pipes 21, so as to prevent the raw materials from sticking in the feeding pipes 21 when the solid and liquid raw materials are mixed and added during feeding, resulting in waste of raw materials and affecting the efficiency of raw material addition.

[0041] Among them, a temperature controller 23 is fixedly installed on the outer side wall of the reaction kettle 2. The temperature controller 23 is electrically connected to an electromagnetic coil 24. The electromagnetic coil 24 is fixedly sleeved in a sunk groove opened in the reaction kettle 2. The temperature controller 23 is also electrically connected to a plurality of constant-temperature electric heating rods 25. The plurality of constant-temperature electric heating rods 25 are uniformly inserted into the temperature control pipe 3. In this way, the temperature controller 23 controls the electromagnetic coil 24 to heat the reaction kettle 2, so that the inside of the reaction kettle 2 reaches the designed temperature for the modified silicone gel reaction. The temperature can be specifically adjusted according to the type of heating modifier to make the reaction efficiency the fastest, and the temperature of the temperature control pipe 3 is regulated by the constant-temperature electric heating rods 25, which is convenient for keeping the modified silicone gel in the temperature control pipe 3 in a stable liquid state.

[0042] Further, sealing partitions 31 are installed at both ends of the temperature control pipe 3. The sealing space formed by the sealing partitions 31 and the temperature control pipe 3 is filled with heat-conducting oil. This is convenient for the constant-temperature electric heating rods 25 to regulate the temperature of the temperature control pipe 3 by using the heat-conducting oil. It should be noted that the temperature regulated by the constant-temperature electric heating rods 25 is slightly higher than the critical temperature at which the solid phase of the modified silicone gel is transformed into the liquid phase, which is convenient for the later extrusion of the liquid-phase modified silicone gel to be cooled and transformed into the solid phase.

[0043] In the embodiment of the present invention, please refer toFigures 1 to 7 The centrifugal liquid guiding mechanism 6 includes a mounting bracket 61 fixedly installed inside the temperature control tube 3. Liquid guiding tube covers 62 are fixedly installed at both ends of the mounting bracket 61. A hollow tube 63 is rotatably installed between the two liquid guiding tube covers 62. A large gear 64 is fixedly sleeved on the outer side wall of the hollow tube 63. A waterproof motor 65 is embedded in the mounting bracket 61. A small gear 66 is fixedly sleeved on the output end of the waterproof motor 65. The small gear 66 meshes with the large gear 64. Among the two liquid guiding tube covers 62, the liquid guiding tube cover 62 close to one end of the gel pump 5 is communicated with the output end of the gel pump 5, and the liquid guiding tube cover 62 at the end away from the gel pump 5 is communicated with a gel pump 67;

[0044] It should be noted that when the centrifugal liquid guiding mechanism 6 is in use, after the gel pump 5 injects the liquid silicone gel into the hollow tube 63 through the liquid guiding tube cover 62, the waterproof motor 65 is started synchronously. The waterproof motor 65 drives the small gear 66 to rotate. The small gear 66 meshes with the large gear 64, thereby driving the hollow tube 63 to rotate at a high speed, centrifugally rotating the liquid modified silicone gel flowing into the hollow tube 63, centrifugally discharging the bubbles in the liquid silicone gel. After discharging the bubbles, the gel pump 67 is used to inject the liquid modified silicone gel into the robot production template for cooling to obtain high-quality solid-phase modified silicone gel;

[0045] And in this embodiment:

[0046] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a liquid collecting tank 81 is installed at the bottom end of the sealing cover 8. A distillation cover 82 is installed on the liquid collecting tank 81. The distillation cover 82 is provided with a through hole through which the stirring mechanism 9 passes. An exhaust pipe column 83 is installed at the top end of the sealing cover 8;

[0047] It should be noted that during stirring, the sealing cover 8 uses the distillation cover 82 to collect the steam discharged from the stirred liquid modified silicone gel in the reaction kettle 2, and uses the liquid collecting tank 81 to collect distilled water, improving the stirring quality of the liquid silicone gel, and using the exhaust pipe column 83 for exhaust. It should be noted that when it is necessary to perform pressure stirring on the reaction kettle 2, it can be pressurized by closing the exhaust pipe column 83.

[0048] In an embodiment of the present invention, please refer to Figures 1 to 7 , the stirring mechanism 9 includes a transmission pipe 91 rotatably installed on the sealing cover 8. A stirring motor 92 for driving the transmission pipe 91 to rotate is installed on the sealing cover 8. A plurality of stirring rods 93 are uniformly installed at one end of the transmission pipe 91 extending into the reaction kettle 2;

[0049] It should be noted that when the stirring mechanism 9 is in use, after the raw materials are introduced into the reaction kettle 2, the stirring motor 92 is started to drive the transmission pipe 91 to rotate. The transmission pipe 91 drives a plurality of stirring rods 93 to rotate synchronously, so as to stir the raw materials introduced into the reaction kettle 2.

[0050] Furthermore, a plurality of stirring rods 93 are all rotatably connected to the transmission pipe 91, and a first bevel gear 94 is fixedly sleeved at one end of each of the plurality of stirring rods 93 extending into the transmission pipe 91. A plurality of short rods 95 are uniformly installed at the other ends of the plurality of stirring rods 93. A fixing rod 96 is inserted into the transmission pipe 91. The fixing rod 96 passes through the sealing gate 72 and is fixedly connected to the temperature control pipe 3. A plurality of second bevel gears 97 are uniformly installed on the fixing rod 96. The second bevel gear 97 meshes with the corresponding first bevel gear 94. In this way, when the transmission pipe 91 rotates and the stirring rod 93 follows the transmission pipe 91 to rotate, the first bevel gear 94 meshes with the second bevel gear 97, so as to drive the stirring rod 93 to rotate self - rotatably, thereby driving the short rod 95 to rotate, improving the overall stirring efficiency and making the raw materials in the reaction kettle stirred more efficiently and evenly.

[0051] A process for a preparation device of modified solid - phase silicone gel for robot skin includes the following steps:

[0052] S1. Raw material introduction: Before introduction, first seal the connection between the conduit 4 and the reaction kettle 2 by using the gate member 7. Then, according to the proportion, the raw materials for preparing the solid - phase silicone gel, namely sodium silicate, silicate ester, hydrochloric acid, solvent, surfactant, cross - linker and catalyst, are sequentially introduced into the reaction kettle 2 through the feed pipe 21 one by one. When introducing, the solid and liquid raw materials are separated according to their properties and introduced from two feed pipes 21.

[0053] S2. Stirring and mixing: Start the temperature controller 23 and the stirring motor 92 synchronously. The temperature controller 23 controls the electromagnetic coil 24 to heat up the reaction kettle 2 to the reaction set temperature, heating the raw materials from the solid phase to the liquid phase. The stirring motor 92 drives the transmission pipe 91 to rotate. When the transmission pipe 91 rotates, it drives the stirring rod 93 to rotate following the transmission pipe 91 and at the same time drives the stirring rod 93 to rotate self - rotatably, thereby driving the short rod 95 to rotate synchronously, and then fully stirring the raw materials in the reaction kettle 2 to prepare liquid silicone gel. When stirring, the sealing cover 8 uses the distillation cover 82, the liquid collection tank 81 and the exhaust pipe column 83 to exhaust and evaporate water vapor, reducing the liquid impurities of the silicone gel.

[0054] S3. Debinding treatment: After completing S2, control the hydraulic rod 71 of the gate member 7 to drive the rod-shaped sealing gate 72 to move downward along the conduit 4 until the sealing gate 72 moves below the glue outlet hole 401. Then start the gel pump 1 5 to introduce the liquid silicone gel flowing into the conduit 4 into the hollow tube 63 through the liquid guide tube cover 62. When introducing, synchronously start the waterproof motor 65. The waterproof motor 65 meshes with the large gear 64 through the small gear 66, thereby driving the hollow tube 63 to rotate at a high speed to perform centrifugal degassing on the liquid silicone gel flowing into the hollow tube 63, further reducing the bubbles in the liquid silicone gel. After sufficient centrifugal exhaust, the preparation of the liquid silicone gel of the modified solid-phase silicone gel is completed. The liquid silicone gel is discharged into the mold for manufacturing the robot through the gel pump 2 67 and then cooled.

[0055] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.

10. The process for preparing the modified solid phase silica gel for robot skin according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Raw material introduction: before introduction, the connection between the conduit (4) and the reaction kettle (2) is sealed by using a gate member (7), and then the raw materials for preparing the solid phase silica gel, sodium silicate, silicate, hydrochloric acid, solvent, surfactant, crosslinking agent and catalyst are introduced into the reaction kettle (2) in sequence through the feed pipe (21) according to the proportion. During the introduction, the raw materials are introduced into the reaction kettle (2) separately in solid and liquid according to the properties of the raw materials. S2, stirring and mixing: synchronously starting the temperature controller (23) and the stirring motor (92), the temperature controller (23) controls the electromagnetic coil (24) to heat the reactor (2) to the set reaction temperature, heating the raw materials from the solid phase to the liquid phase, the stirring motor (92) drives the transmission tube (91) to rotate, and when the transmission tube (91) rotates, it drives the stirring rod (93) to rotate along with the transmission tube (91), thereby driving the stirring rod (93) to rotate, thereby driving the short rod (95) to rotate synchronously, and then fully stirring the raw materials in the reactor (2) to prepare liquid silica gel. During stirring, the sealing cover (8) uses the distillation cover (82), the liquid collecting tank (81) and the exhaust pipe column (83) to exhaust and evaporate water vapor, thereby reducing liquid impurities in the silica gel; S3, glue discharge treatment: after completing S2, the hydraulic rod (71) of the gate member (7) drives the sealing gate (72) to move downward along the conduit (4) until the sealing gate (72) moves to the bottom of the glue outlet hole (401), and then the gel pump (5) is started to guide the liquid silicone gel flowing into the conduit (4) into the hollow tube (63) through the liquid guide tube cover (62). During the introduction, the waterproof motor (65) is started synchronously. The waterproof motor (65) meshes with the large gear (64) through the small gear (66), thereby driving the hollow tube (63) to rotate at a high speed, and the liquid silicone gel flowing into the hollow tube (63) is centrifugally degassed to further reduce the bubbles in the liquid silicone gel. After sufficient centrifugal exhaust, the preparation of the liquid silicone gel of the modified solid phase silicone gel is completed, and the liquid silicone gel is discharged into the mold for manufacturing the robot through the gel pump (67) for cooling.
