A composite type holding apparatus 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 4.
The composite type holding apparatus 100 according to the embodiment of the present invention, as shown in fig. 1 and 4, includes: the suction cup comprises a body 1, a first suction cup 2 and a second suction cup 3. A first air flow path 11 and a second air flow path 12 are defined in the body 1, the first air flow path 11 having a first quick-opening inlet 111 and a first outlet 112, the second air flow path 12 having a second quick-opening inlet 121 and a second outlet 122. The first suction cup 2 is arranged on the body 1, one end of the first suction cup 2 forms a first suction end 21 and the other end is communicated with the first air flow channel 11. At least part of the second suction cup 3 is arranged in the first suction cup 2, one end of the second suction cup 3 forms a second suction end 31, the other end of the second suction cup 3 is communicated with the second airflow channel 12, and the second suction end 31 and the first suction end 21 are positioned at the same end of the first suction cup 2; the first fast-through inlet 111 is used for injecting air flow to the first outlet 112, so that the first air flow channel 11 constitutes a first vacuum generator, and the first suction end 21 forms a negative pressure region; the second quick-opening inlet 121 is used for jetting the air flow toward the second outlet 122, so that the second air flow channel 12 constitutes a second vacuum generator and the second suction end 31 forms a negative pressure region. In addition, the combined type holding device 100 further comprises a pressure detection part 4, the pressure detection part 4 is used for detecting the air pressure value of one of the first vacuum generator and the second vacuum generator, and the pressure detection part 4 is used for controlling the start and stop of the other one of the first vacuum generator and the second vacuum generator.
For convenience of description, in order to better describe the composite type holding device 100 in the embodiment of the present invention, the following description will be made by taking the example that the flow rate of the first fast-opening inlet 111 is determined to be larger than the flow rate of the second fast-opening inlet 121, in which case the pressure detecting element 4 is used for detecting the air pressure value of the second vacuum generator, and the pressure detecting element 4 is used for controlling the start and stop of the first vacuum generator. Therefore, in the actual use process, the two vacuum generators can be used according to different material characteristics, and the use method is flexible. As shown in fig. 2, when the composite holding apparatus 100 holds a material that is flat, the second fast-opening inlet 121 injects an air flow to the second outlet 122, so that the second air flow channel 12 forms a second vacuum generator, which is equivalent to activating the second vacuum generator, so that the second suction port end 31 forms a negative pressure area, so that a higher vacuum negative pressure can be established between the second suction cup 3 and the surface of the material, and the second suction cup 3 can suck the material. As shown in fig. 3, when the composite holding apparatus 100 holds a material that is not flat, within a half minute to two minutes after the second vacuum generator is started, if the pressure detecting element 4 detects that the air pressure value of the second vacuum generator is greater than the preset value, the pressure detecting element 4 may control the first vacuum generator to be turned on to hold the material. Therefore, whether the first vacuum generator is started or not can be intelligently selected according to the flatness of the surface of the material. Here, when the first quick-opening inlet 111 injects the air flow toward the first outlet 112, the first air flow path 11 constitutes a first vacuum generator, which is equivalent to activating the first vacuum generator, so that the first suction port 21 forms a negative pressure region. If the flow rate of the first fast-passing inlet 111 is large, even if the first suction cup 2 is not tightly attached to the surface of the material and air leaks, a certain negative pressure can be generated at the position of the first suction cup 2, and the material with a certain weight can be sucked up. .
At least part of the second suction cup 3 is arranged in the first suction cup 2, so that the composite type holding device 100 is highly integrated, and the occupied space of the composite type holding device 100 can be effectively reduced. And because the second sucking disc 3 is just in first sucking disc 2 department, therefore when changing vacuum generator, the sucking disc need not shift, consequently is favorable to practicing thrift the absorption time, promotes and holds efficiency.
Of course, the flow rate of the first fast-opening inlet 111 may also be smaller than the flow rate of the second fast-opening inlet 121, in which case the pressure detecting element 4 is used for detecting the air pressure value of the first vacuum generator, and the pressure detecting element 4 is used for controlling the start and stop of the second vacuum generator. And the intelligent material holding can be realized. The definitions herein are for the purpose of more clearly describing the interaction of the components and are not intended to be limiting.
According to the combined type holding device 100 provided by the embodiment of the invention, the form of the matching operation of the two types of vacuum generators is provided, the application range is wide, and the matched vacuum generators can be intelligently started to work when materials with different characteristics are sucked, so that the gas consumption is saved. At least part of the second suction cup 3 is arranged in the first suction cup 2, and the composite type suction device 100 is integrally arranged, so that the occupied space of the composite type suction device 100 can be effectively reduced. And when the characteristic change of the target material needs to be changed into the vacuum generator, the sucking positions of the two suckers are basically consistent, so that the positions of the suckers do not need to be changed greatly. And when the sucking disc adjusting position, need not consider the condition that another sucking disc was walked around to a sucking disc, consequently can reduce the adjustment time, improve and hold efficiency.
In some embodiments, when the pressure detecting member 4 is used to detect the first vacuum generator, the sensing end of the pressure detecting member 4 is provided in the first air flow path 11 or the first suction pad 2. Here, the sensing end of the pressure sensor 4 can be arranged in the first air flow channel 11 and also in the first suction cup 2, thereby providing more flexible and various configurations to adapt to different materials.
When the pressure detecting member 4 is used to detect the second vacuum generator, the sensing end of the pressure detecting member 4 is disposed in the second air flow path 12 or the second suction cup 3. Here, the sensing end of the pressure sensor 4 can be arranged in the second air flow channel 12 and also in the second suction cup 3, thereby providing more flexible and various configurations to adapt to different materials.
Alternatively, the pressure detecting member 4 may be a vacuum pressure sensor. Taking the example that the flow rate of the second vacuum generator is smaller than that of the first vacuum generator, as shown in fig. 2, the second vacuum generator can establish a higher vacuum negative pressure when the second suction cup 3 is well attached to the material, and can suck up the material. When the surface of the material is uneven and the second sucker 3 is poorly attached to the material, the material cannot be sucked up, negative pressure in the vacuum loop is poorly established at the moment, and the vacuum negative pressure is far lower than the level of the first sucker 2 when the material is well attached. As shown in fig. 3, when the vacuum pressure sensor detects that the negative pressure is not well established and exceeds the set threshold, the first vacuum generator is started, and the first suction cup 2 is used for absorbing the materials. Therefore, the consumption of gas can be reduced under the condition of ensuring that the materials are sucked up.
In some embodiments, as shown in FIG. 4, the second air flow channel 12 is located inside the first air flow channel 11, and the second outlet 122 communicates with the first air flow channel 11 to be exhausted by the first outlet 112. Therefore, the structure of the combined type suction device 100 is more compact, the layout is more reasonable, the integration degree of the combined type suction device 100 is further improved, and the occupied space of the combined type suction device 100 is reduced. In addition, the layout is also favorable for the flow of air flow, and the suction efficiency of the materials is further improved.
In some embodiments, as shown in fig. 4, the second suction cup 3 is plural. It can be understood that the arrangement of the plurality of second suction cups 3 can increase the probability of picking up the uneven material, for example, the probability of picking up the flat part of the surface of the uneven material can be increased, thereby increasing the holding efficiency of the composite holding device 100 and reducing the gas consumption.
Specifically, as shown in fig. 4, there is one first air flow path 11, and there are a plurality of second air flow paths 12 corresponding to the second suction cups 3 one to one. Therefore, the layout can further improve the integration degree of the combined type suction device 100, is beneficial to the flow of air flow, and further improves the suction efficiency of the combined type suction device 100.
In some embodiments, the first suction cup 2 and the second suction cup 3 are both flexible tubes. The first sucker 2 and the second sucker 3 are convenient to lift, and the mutual blocking effect between the first sucker 2 and the second sucker 3 can be reduced.
Specifically, when the first suction cup 2 and the second suction cup 3 are both at the natural elongation length, the second suction end 31 of the second suction cup 3 is located outside the first suction cup 2. Therefore, the second suction cup 3 can be fully contacted with the material, and the situation that the second suction cup 3 is blocked by the first suction cup 2 is reduced.
In some alternative embodiments, the second suction end 31 of the second suction cup 3 is located within the first suction cup 2 when the first suction cup 2 and the second suction cup 3 are each shortened to the shortest. When starting first vacuum generator like this, can make second sucking disc 3 shrink inwards more easily, reduce the outside thrust that second sucking disc 3 pushed the material, make first sucking disc 2 inseparabler with the material contact, adsorb more firmly.
In some embodiments, as shown in fig. 4, the body 1 comprises: a first shell portion 13, an adapter ring 14, a second shell portion 15, and a third shell portion 16. One end of the first housing portion 13 is provided with a first outlet 112, and the first housing portion 13 is provided with a first quick-access inlet 111. An adapter ring 14 is attached to the other end of the first housing portion 13. The second housing part 15 is connected to the adapter ring 14, and the first suction cup 2 is connected to the second housing part 15. The second casing portion 15 defines the first air flow passage 11 therein, and the second casing portion 15 is provided with a second quick-access inlet 121. The third shell portion 16 is disposed in the second shell portion 15, the third shell portion 16 internally defines the second airflow passage 12, and the second suction cup 3 is coupled to the third shell portion 16. Therefore, the structural strength of the composite suction device 100 can be improved, the integration degree of the composite suction device 100 can be further improved, and the occupied space of the composite suction device 100 can be reduced. In addition, the first casing part 13 and the third casing part 15 are not connected through a pipeline, so that the air flow can be favorably circulated, the distance between the first casing and the first suction tray 2 is reduced, and the problem of reduction of the suction flow of the first suction tray 2 caused by the overlong pipeline is solved.
