Description
Technical Field
[0001] The present application relates to the field of soft robotics technology, and in particular to a detectable multi-type air pressure output device and method. Background Art
[0002] At present, in the field of soft robots, for the positive and negative pressure control systems in the same air pressure-driven scenario, the common method is to use the positive pressure control system and the negative pressure control system separately. This will result in the overall structure of the positive and negative pressure control system being large in size, high in cost, and single in control. At the same time, the existing integrated positive and negative pressure control system can only perform positive pressure control or negative pressure control separately at the same time, and cannot perform positive and negative pressure control at the same time. In addition, the existing air pressure control technology has low adjustment accuracy and cannot effectively meet the needs.
[0003] It should be pointed out that in current soft robots, environmental detection and feedback are particularly important, which can analyze and adjust the robot's motion state. Most traditional soft robots use pressure sensors, metal strain gauges, etc. that are directly assembled on the surface of the soft robot, and corresponding circuit modules need to be built. They have poor safety and limited usage scenarios. They cannot be used in humid environments or underwater environments, and cannot meet the detection needs of different environments.
[0004] Therefore, the existing technology has defects and deficiencies and needs further improvement and development. Summary of the Invention
[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a detectable multi-type air pressure output device and method, aiming to solve the problem that the air pressure control system of the soft robot in the existing technology cannot simultaneously control multiple groups of air pressure drives and simultaneously control the output of positive and negative pressure outputs.

By arranging a two-way solenoid valve between the three-way solenoid valve and the air pressure drive mechanism and connecting it to the control mechanism, the two-way solenoid valve can be controlled to close the air pressure drive mechanism.

[0071] Please refer to Figures 1 to 2 In the first embodiment of the present application, a detectable multi-type air pressure output device 100 is provided, and the detectable multi-type air pressure output device 100 is used for a soft robot; specifically, the detectable multi-type air pressure output device 100 includes: a high-pressure air source mechanism 17, a control mechanism 18, a plurality of air pressure output mechanisms 16, a plurality of air pressure drive modules 7 and a plurality of air pressure sensors 8; the high-pressure air source mechanism 17 is provided with a positive high-pressure air source 1 and a negative high-pressure air source 2; a plurality of the air pressure output mechanisms 16 are connected to the high-pressure air source mechanism 17; a plurality of the air pressure drive modules 7 are respectively connected to a plurality of the air pressure sensors 8 The output mechanisms 16 are connected one-to-one; several of the air pressure sensors 8 are respectively arranged in one-to-one correspondence with several air pressure drive modules 7; the control mechanism 18 is electrically connected to the high-pressure air source mechanism 17, several air pressure output mechanisms 16 and several air pressure sensors 8; wherein, the air pressure output mechanism 16 is provided with a connected three-way solenoid valve 5 and a two-way solenoid valve 6, the two-way solenoid valve 6 is connected between the air pressure drive module 7 and the first port of the three-way solenoid valve 5, the second port of the three-way solenoid valve 5 is connected to the positive high-pressure air source 1, and the third port of the three-way solenoid valve 5 is connected to the negative high-pressure air source 2.
[0072] When the soft robot is running, the high-pressure air source mechanism 17 is used to provide a positive high-pressure air source 1 and a negative high-pressure air source 2, which provides a guarantee for the air pressure output mechanism 16 to output the positive high-pressure air source 1 and the negative high-pressure air source 2. Then the air pressure output mechanism 16 outputs the positive high-pressure air source 1 or the negative high-pressure air source 2 to the air pressure output mechanism 16. The air pressure sensor 8 is used to detect the working pressure or environmental parameters of the air pressure drive module 7. Specifically, the high-pressure air source mechanism 17 is connected to a plurality of air pressure output mechanisms 16, and the control mechanism 18 is connected to a plurality of air pressure output mechanisms 16; that is, the air pressure output mechanisms 16 are all connected to a positive high-pressure air source 1 (such as a compressor) and a negative high-pressure air source 2 (such as a vacuum pump), and are all capable of outputting a positive high-pressure air source 1 and a negative high-pressure air source 2; by electrically connecting all the air pressure output mechanisms 16 to the control mechanism 18, the control mechanism 18 can simultaneously control all the air pressure output mechanisms 16, and simultaneously control different air pressure output mechanisms 16 to simultaneously output a positive high-pressure air source 1 and / or a negative high-pressure air source 2, thereby driving the air pressure drive module 7 corresponding to each air pressure output mechanism 16 to operate; in this process, the corresponding two-way solenoid valves 6 are all in the open state, and the first port and the second port of the three-way solenoid valve 5 of the air pressure output mechanism 16 that outputs the positive high-pressure air source 1 are open. , the first port and the third port of the three-way solenoid valve 5 of the air pressure output mechanism 16 that outputs the negative high-pressure air source 2 are opened; at the same time, the air pressure sensor 8 corresponding to each air pressure driving module 7 synchronously detects the real-time working pressure of the air pressure driving module 7, and feeds back to the control mechanism 18, thereby realizing the detectability of the output air pressure of the air pressure output mechanism 16; at the same time, when the air pressure driving module 7 does not need to be driven, the control mechanism 18 controls the two-way solenoid valve 6 to close, so that the air pressure driving module 7 is in a sealed state. At this time, the air pressure sensor 8 can detect the real-time pressure changes of the closed air pressure driving module 7, and thus indirectly obtain the environmental parameters of the air pressure driving module 7, such as the ambient air pressure. When the ambient air pressure increases, the air pressure driving module 7 is compressed, and the internal pressure increases synchronously, otherwise it decreases synchronously; for example, the ambient temperature and the external temperature change will also cause the pressure inside the air pressure driving module 7 to change.
[0073] That is, by connecting the high-pressure gas source mechanism 17 to a plurality of groups of gas pressure output mechanisms 16, each group of gas pressure output mechanisms 16 is equipped with a positive high-pressure gas source 1 and a negative high-pressure gas source 2, and by providing a three-way solenoid valve 5 on the gas pressure output mechanism 16, the gas pressure output mechanism 16 has a structure for switching the output of the positive high-pressure gas source 1 and the negative high-pressure gas source 2. By providing a control mechanism 18 and electrically connecting it to the plurality of gas pressure output mechanisms 16, the three-way solenoid valve 5 can be controlled; thus, a single group of control mechanisms 18 can simultaneously control a plurality of groups of gas pressure output mechanisms 16. , and can simultaneously control different air pressure output mechanisms 16 to simultaneously output positive high-pressure air source 1 and / or negative high-pressure air source 2; by arranging a two-way solenoid valve 6 between the three-way solenoid valve 5 and the air pressure drive mechanism, and connecting it to the control mechanism 18, the two-way solenoid valve 6 can be controlled to close the air pressure drive mechanism, and by arranging an air pressure sensor 8 electrically connected to the control mechanism 18 at one end of the air pressure drive mechanism, the air pressure value of the air pressure drive mechanism can be detected, and the environmental parameters of the soft robot can be indirectly known from the change in the air pressure value of the air pressure drive mechanism.

[0075] It can be understood that by providing the positive proportional valve 3 and the negative proportional valve 4, the air pressure output mechanism 16 is stably and controllably connected to the positive high-pressure air source 1 and the negative high-pressure air source 2 of the high-pressure air source mechanism 17, so that the air pressure output mechanism 16 can output both the positive high-pressure air source 1 and the negative high-pressure air source 2. The positive proportional valve 3, the negative proportional valve 4, the three-way solenoid valve 5, and the two-way solenoid valve 6 are all electrically connected to the control mechanism 18, thereby facilitating the control of the operation of the positive proportional valve 3, the negative proportional valve 4, the three-way solenoid valve 5, and the two-way solenoid valve 6 by the control mechanism 18.

[0077] It can be understood that by setting the second port of the three-way solenoid valve 5 connected to the positive high-pressure air source 1 to the normally closed end, the air tightness of the detectable multi-type air pressure output device 100 is effectively guaranteed; by setting the third port of the three-way solenoid valve 5 connected to the negative high-pressure air source 2 to the normally open end, it is beneficial to maintain the air pressure balance in the air pressure drive module 7.

[0083] It can be understood that the host computer 15 serves as a human-computer interaction platform for the detectable multi-type air pressure output device 100, and the user can control the operation of the detectable multi-type air pressure output device 100 through the host computer 15; specifically, the control window is set on the host computer body 157, and the connection control module 151, the air pressure control module 152, the real-time air pressure feedback module 158 and the two-way solenoid valve control switch 154 are all set on the control window. The user operates the connection control module 151, the air pressure control module 152, the real-time air pressure feedback module 158 and the two-way solenoid valve control switch 154 in the control window to control the operation of the detectable multi-type air pressure output device 100; specifically, the connection control module 151 is set as a connection control button or a connection control touch key; The air pressure control module 152 is a plurality of air pressure control knobs; the plurality of air pressure sensors 8 transmit the detected air pressure data to the controller, and the controller transmits the air pressure data to the real-time air pressure feedback module 158, and the real-time air pressure feedback module 158 is configured as a real-time air pressure feedback curve display component 153 and an air pressure feedback value display component 155, and the real-time air pressure feedback curve display component 153 is configured as a real-time air pressure feedback value display window, and the real-time air pressure feedback value display window displays the real-time air pressure feedback value of the plurality of air pressure data; the real-time air pressure feedback curve display component 153 is configured as a real-time air pressure feedback value window, and the real-time air pressure feedback value display window displays the air pressure feedback value curve of the plurality of air pressure data; the two-way solenoid valve control switch 154 is also configured in plurality.
[0084] It can be understood that by setting the connection control module 151, the connection between the host computer 15 and the controller 9 can be effectively controlled; by setting the air pressure control module 152, the operating pressure of the air pressure drive module 7 can be controlled; by setting the real-time air pressure feedback module 158, the operating pressure and environmental parameters of the air pressure drive module 7 detected by the air pressure sensor 8 can be displayed in real time; by setting the two-way solenoid valve control switch 154, the on and off of the two-way solenoid valve 6 can be controlled, thereby switching the air pressure drive mode or the detection mode.

[0086] It can be understood that by setting the instruction sending control module 156 (such as the instruction start control button), the correctness of the operation of the host computer 15 can be guaranteed. After setting various parameters, the instruction sending control module 156 will be triggered to send instructions to the controller 9, thereby avoiding misoperation.
[0087] Please refer to Figure 5 In the second embodiment of the present application, a detectable multi-type air pressure output method is also provided. The detectable multi-type air pressure output method is completed based on the detectable multi-type air pressure output device in the above embodiment of the present application, and is used to simultaneously control multiple groups of air pressure output mechanisms of the soft robot through a set of control mechanisms to output positive high-pressure air source or negative high-pressure air source to the corresponding air pressure driving module, and detect the working pressure of the air pressure driving module and monitor environmental parameters (such as pressure or temperature).
[0088] Specifically, the detectable multiple types of air pressure output methods include:
[0089] Step S100 : The control mechanism controls a plurality of the two-way solenoid valves to open, and connects the air pressure drive module corresponding to each two-way solenoid valve to the first port of the three-way solenoid valve.
[0090] It can be seen that when the detectable multi-type air pressure output device is in operation, the control mechanism first controls the opening of a plurality of two-way solenoid valves to connect the air pressure drive module with the air pressure output mechanism, thereby providing a guarantee for driving the air pressure drive module; specifically, the step S100 includes:
[0091] The host computer receives a plurality of two-way solenoid valve opening instructions and sends them to the controller;
[0092] The controller receives several two-way solenoid valve opening instructions, and drives the PLC control board through the I / O port to open several corresponding two-way solenoid valves, connecting each corresponding pneumatic drive module with the three-way solenoid valve.
[0093] It can be seen that the user controls the opening and closing of the corresponding two-way solenoid valve control switch of the corresponding pneumatic drive module by operating the two-way solenoid valve control switch of the upper computer, so that the pneumatic drive module and the pneumatic output mechanism are connected; it should be pointed out that the upper computer can also automatically generate the required two-way valve solenoid valve opening or closing instructions by the two-way solenoid valve control switch and transmit them to the controller.
[0094] Step S200: The control mechanism receives a plurality of air pressure control instructions as input, and controls the corresponding second port or third port of the three-way solenoid valve to open according to each air pressure control instruction.
[0095] It can be seen that the control mechanism controls the opening of the second port or the third port of the corresponding three-way valve solenoid valve according to the air pressure values corresponding to the air pressure value control instructions; and then the control mechanism simultaneously controls different air pressure output mechanisms to output positive high-pressure air source and / or negative high-pressure air source to the corresponding air pressure drive module. Specifically, the step S200 includes:
[0096] The air pressure control module receives a plurality of set air pressure value control instructions and sends them to the controller through the air pressure control module;
[0097] The controller receives the air pressure control instructions and determines whether the control air pressure value corresponding to each air pressure control instruction is a positive air pressure value or a negative air pressure value;
[0098] When all the control air pressure values are positive air pressure values, the controller drives the PLC control board through the I / O port to open the second port of all three-way solenoid valves; when all the control air pressure values are negative air pressure values, the controller drives the PLC control board through the I / O port to open the third port of all three-way solenoid valves; when part of the control air pressure values are positive air pressure values and part of them are negative air pressure values, the controller drives the PLC control board through the I / O port to open the second port of the three-way solenoid valve corresponding to the positive air pressure value, and open the third port of the three-way solenoid valve corresponding to the negative air pressure value.
[0099] It can be seen that the user can set several air pressure value control instructions through the air pressure control module of the upper computer. It should be noted that the upper computer can also automatically generate several air pressure value control instructions through the air pressure control module; then, all the air pressure value control instructions are sent to the controller, and the controller receives several air pressure value control instructions corresponding to the air pressure values of the positive high-pressure air source or the negative high-pressure air source; the second port of the three-way valve solenoid valve of the air pressure output mechanism corresponding to the air pressure value control instruction of the positive high-pressure air source is opened, and the positive high-pressure air source is output to the air pressure drive module; the third port of the three-way valve solenoid valve of the air pressure output mechanism corresponding to the air pressure value control instruction of the negative high-pressure air source is opened, and the negative high-pressure air source is output to the air pressure drive module; thereby realizing the simultaneous control of multiple groups of air pressure output mechanisms to output positive high-pressure air sources and / or negative high-pressure air sources.
[0100] In step S300, the high-pressure air source mechanism outputs positive air pressure or negative air pressure to the corresponding air pressure driving module through the air pressure output mechanism and the two-way solenoid valve in sequence; at the same time, several of the air pressure sensors detect the real-time air pressure value of the air pressure driving module one by one and send it to the control mechanism.
[0101] It can be seen that in the detectable multi-type air pressure output method, a group of high-pressure air source mechanisms are connected to all air pressure output mechanisms, and each air pressure driving module is equipped with a two-way solenoid valve, a three-way valve solenoid valve, a positive proportional valve or a negative proportional valve and a positive high-pressure air source component or a negative high-pressure air source component; at the same time, while outputting the air source to the air pressure driving module; synchronously, the air pressure sensor detects the working pressure of the air pressure driving module in real time one by one, and feeds back to the controller and the host computer, and the real-time air pressure feedback module displays the air pressure feedback curve and the air pressure feedback value, thereby realizing real-time detection of the air pressure driving module and real-time detection of the air pressure output by the air pressure output mechanism.
[0102] In step S400 , the control mechanism controls the two-way solenoid valves to be closed, and the air pressure sensors detect the real-time environmental parameters of the air pressure driving module in a one-to-one correspondence manner and send the detected parameters to the control mechanism.
[0103] It can be seen that the control mechanism receives or generates several two-way valve solenoid valve closing instructions, and closes the corresponding two-way valve solenoid valve, so that the pneumatic drive module (such as the airbag structure) is in a sealed state; at this time, the pressure inside the pneumatic drive module can be affected by the environmental parameters of the soft robot (such as ambient pressure or ambient temperature), and then the pressure in the pneumatic drive module can be detected by the pneumatic pressure sensor, and the environmental parameters of the soft robot can be indirectly known, and it is not affected by the scene and has high safety.
[0104] It should be understood that the application of this application is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to this application.
