Description
Technical Field
The utility model relates to a sucking disc especially relates to a vacuum chuck of suck-back device is prevented in area.
Background
The vacuum sucker is one of vacuum equipment actuators, the sucker is made of nitrile rubber, and is widely applied to various vacuum sucking and holding equipment, for example, the problems of insufficient suction force, extremely short service life of the vacuum rubber sucker and the like caused by poor adsorption and buffering performance due to the fact that a vacuum sucking crane in a household air conditioner production workshop at present adopts a rubber sucker, and serious potential safety hazards of industrial injury exist.
With the rise of the robot industry, a plurality of robot products applied to special scenes appear at present, for example, the robot is suitable for some robots which work in high-risk environments and need vacuum suction cups. The bottom of the vacuum sucker is generally in a disc shape, the top of the vacuum sucker is connected with a vacuum pump, and when a machine is adsorbed on a wall surface through the vacuum sucker to work, the machine can be separated from the wall surface due to gas backflow caused by abnormal procedures, so that great danger is caused to people and articles on the ground. If the pump does not reach the specified limit pressure during operation, the thicker steel plate cannot be sucked up or frequently falls off midway due to insufficient suction force, so that potential safety hazards and surface damage are caused.
Disclosure of Invention
An object of the utility model is to provide a solve above-mentioned problem, can effectively prevent the gas refluence, avoid the sucking disc to drop a vacuum chuck of suck-back device is prevented in area.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a vacuum chuck with a suck-back prevention device comprises a pipe body and a chuck body, wherein the top of the pipe body is connected with a vacuum pump, and the bottom of the pipe body is communicated with the chuck body;
the inner wall of the pipe body is provided with a valve for preventing suck-back, the number of the valves is 3-6, the valves only enable gas to pass upwards, a first pressure sensor is arranged on the position, close to one valve, of the inner wall of the pipe body, and when the valve is opened, the first pressure sensor can be touched;
the sucker body comprises a plurality of layers of suckers which are sequentially arranged from top to bottom, the top of the sucker positioned on the lower layer is flush with the bottom of the sucker positioned on the upper layer, and the bottoms and the tops of the two adjacent suckers are communicated through a connecting part;
the inner wall of the uppermost sucker is provided with a second pressure sensor;
the first pressure sensor and the second pressure sensor are used for respectively acquiring pressure data of an installation position and sending the pressure data to the controller, and the controller is used for controlling the vacuum pump to work according to the pressure data.
Preferably, the method comprises the following steps: the connecting part is made of the same material as the sucker and is integrally formed.
Preferably, the method comprises the following steps: the sucking discs of the sucking disc body are 3-5 layers.
Compared with the prior art, the utility model has the advantages of:
first pressure sensor for judge whether the valve is opened, when vacuum pump work and begin to breathe in, the opening of valve can keep opening, make gaseous from supreme the conducting down, realize the adsorption function. When gas backflow occurs, the gas can generate downward force on the valve, so that the valve becomes a closed state, the valve is separated from the first pressure sensor, and the first pressure sensor cannot detect pressure data.
The second pressure sensor is used for judging the whole adsorption state of the sucker body, when the sucker body is vacuumized, the multilayer suckers can be shortened and attached together, pressure is generated on the second pressure sensor, if the adsorption force is insufficient, the pressure is small, and whether the vacuumizing effect is achieved or not can be judged through the pressure threshold value preset on the second pressure sensor.
The utility model discloses can prevent suck-back through the valve, thereby judge through first pressure sensor that the valve state judges whether take place gas refluence, the sucking disc body through the multilayer sucking disc combines second pressure sensor's data, judges whether the sucking disc body is stable to be adsorbed. Thereby guaranteed vacuum chuck's effect, prevented to use this utility model's machine because the danger of the reverse departure that abnormal conditions leads to in the course of the work.
Drawings
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic view of the valve of fig. 1 in an open configuration.
In the figure: 1. a pipe body; 2. a suction cup body; 3. a valve; 4. a first pressure sensor; 5. a second pressure sensor; 6. and (4) sucking discs.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Example 1: referring to fig. 1 and 2, the vacuum chuck with the suck-back prevention device comprises a pipe body 1, a chuck body 2, a controller and a vacuum pump, wherein the top of the pipe body 1 is connected with the vacuum pump, and the bottom of the pipe body is communicated with the chuck body 2;
the inner wall of the pipe body 1 is provided with a valve 3 for preventing suck-back, the number of the valves 3 is 3-6, gas can only pass upwards, a first pressure sensor 4 is arranged on the inner wall of the pipe body 1 close to one valve 3, and when the valve 3 is opened, the first pressure sensor 4 can be touched;
the sucker body 2 comprises a plurality of layers of suckers 6 which are arranged in sequence from top to bottom, the tops of the suckers 6 on the lower layer are flush with the bottoms of the suckers 6 on the upper layer, and the bottoms and the tops of the two adjacent suckers 6 are communicated through a connecting part;
the inner wall of the uppermost sucker 6 is provided with a second pressure sensor 5;
the first pressure sensor 4 and the second pressure sensor 5 are used for respectively collecting pressure data of the installation position and sending the pressure data to the controller, and the controller is used for controlling the vacuum pump to work according to the pressure data.
The connecting part is made of the same material as the sucker 6 and is integrally formed, and the suckers 6 of the sucker body 2 are 3-5 layers.
In the utility model, the valve 3 has two states, the valve 3 is closed as shown in fig. 1, and the valve 3 is opened as shown in fig. 2. The working process comprises the following steps:
in a normal state, the valve 3 of the present invention is in an open state, as shown in fig. 2.
When the top of the pipe body 1 is connected with a vacuum pump and starts to suck air, the opening of the valve 3 can be kept open, so that the air is conducted from bottom to top, the adsorption function is realized, meanwhile, the multilayer suckers 6 in the sucker body 2 start to be compressed, and the second pressure sensor 5 senses the pressure and can keep working normally; if the pressure is not sensed, the controller controls the vacuum pump to increase the suction force.
When the situation of gas backflow occurs, the gas can exert force on the valve 3, so that the valve 3 is in a closed state, the gas backflow can be prevented, and the opening and closing situation of the valve 3 is judged through the contact situation of the first pressure sensor 4 and the valve 3. The utility model discloses when preventing gas refluence, the cost of material has been controlled as far as possible. The critical problem is solved by the simplest structure.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
