Description

Technical Field

[0001] The utility model relates to the technical field of vacuum suction cups, in particular to a flat suction device. Background Art

[0002] Compared with traditional mechanical clamping technology, vacuum adsorption devices can absorb some workpieces with flat surfaces that cannot be clamped, such as large-sized, light-weight and regular flat objects such as glass, plates or cartons. The working principle of the vacuum adsorption device is to form a temporary sealed space after the adsorption mechanism contacts the adsorbed object, and by extracting or thinning the air in the sealed space, a pressure difference between the inside and the outside is generated, so that the adsorption mechanism adsorbs the object.

[0003] Traditional adsorption devices are generally upright, that is, the vacuum pump and the air chamber are in the upper and lower positions when working, which causes the height of the overall adsorption device to be too large and unable to adapt to flat scenes. Figure 1 The working schematic diagram of the traditional adsorption device is shown. It can be seen from the figure that the vacuum pipe / vacuum pump is located above the air chamber, and the adsorption port is kept in the same direction as the suction (intake) direction, which leads to the problem of a larger height size.

[0004] The external suction cup of the traditional adsorption device protrudes outside the adsorption device, further increasing the working size and being unable to adapt to flat scenes. Utility Model Content

[0005] The utility model provides a flat adsorption device, which can solve the problem that the adsorption device in the prior art has an overlarge working size and is difficult to adapt to flat scenes.

[0006] A flat adsorption device, comprising:

[0007] A housing, comprising a first receiving cavity and a second receiving cavity arranged along a second direction, the opening surfaces of the first receiving cavity and the second receiving cavity being flush, the thickness of the first receiving cavity along the first direction being smaller than the thickness of the second receiving cavity, and a receiving space being provided on a side of the first receiving cavity away from the opening surface, wherein the first direction and the second direction are perpendicular;

[0008] at least one adsorption component is disposed in the first receiving cavity, and includes an adsorption port, wherein the first adsorption port is connected to the receiving space; and

[0009] The air source component is arranged in the second receiving chamber and is communicated with the adsorption component.

[0010] More preferably, it further comprises at least one terminal adsorption component, which is disposed in the accommodating space and communicated with the adsorption port.

[0011] More preferably, the terminal adsorption member includes an adsorption surface, and the adsorption surface is flush with or protrudes from the side of the second receiving cavity away from the opening surface.

[0012] More preferably, the adsorption component includes an air chamber, a solenoid valve and at least three air pipe openings arranged along the second direction, the air chamber is provided with a plurality of air cavities interconnected with each other, the air pipe openings are connected to the air chambers, the solenoid valve is attached to one side of the air chamber and connected to the air cavity, and the opening and closing of the air pipe openings are controlled by the air cavity.

[0013] More preferably, there are three air pipe openings which are respectively arranged on three adjacent end surfaces of the air chamber, and one of the air pipe openings faces the air source assembly.

[0014] More preferably, there are three air pipe openings and two of them are distributed on a side of the air chamber away from the solenoid valve.

[0015] More preferably, at least one group of adsorption components is included, the number of adsorption components in each group is 2, and the solenoid valves of each group of adsorption components are arranged on the outside of the air chamber.

[0016] More preferably, the air pipe openings arranged on the inner sides of the two air chambers of the adsorption assembly are staggered along the second direction, and the axis center lines of two adjacent air pipe openings are not collinear.

[0017] More preferably, the axis center lines of the two air pipe openings arranged on the side of the air chamber away from the solenoid valve are not collinear.

[0018] More preferably, the dimension of the air source component in the first direction is the shorter dimension of the air source component; the dimension of the adsorption component in the first direction is the shorter dimension of the adsorption component.

[0019] The utility model provides a flat adsorption device, which arranges the air chamber and the air source component horizontally so that the adsorption port is perpendicular to the air inlet direction of the air source component, thereby avoiding the "stack" of the air source component and the air chamber in the vertical direction, thereby reducing the height size of the adsorption device and making the entire adsorption device flat;

[0020] At the same time, by setting different thicknesses for the first storage chamber and the second storage chamber, the smaller size of the adsorption component relative to the gas source component is reasonably utilized. Without sacrificing the power of the gas source component, the height of the first storage chamber is further reduced, which is conducive to the flattening and miniaturization of the adsorption device.

[0030] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0031] Embodiment 1:

[0032] The present utility model provides a flat adsorption device, including a shell 10, an adsorption component and an air source component. The shell 10 is used to accommodate and fix the adsorption component and the air source component. The adsorption component is used to form a pressure difference under the action of negative pressure, so that the object can be adsorbed. The adsorption component is the same as the device with this function in the prior art; the air source component is used to form a negative pressure on the adsorption component. The air source component can use a vacuum pump 20 or other device for sucking gas. In this embodiment, the air source component takes the vacuum pump 20 as an example. It should be noted that the above content is only the working state of the adsorption component when the adsorption device is working normally. The adsorption component can also generate positive pressure. For example, when it is necessary to release parts quickly and the air source component needs to be filled with gas, the adsorption component can also generate positive pressure.

[0033] like Figure 2 and Figure 7 As shown, the definition Figure 2 The Z direction in is the first direction, Figure 2The Y direction in the figure is the second direction, and the first direction and the second direction are perpendicular to each other. The housing 10 includes a first receiving cavity 11 and a second receiving cavity 12, and the first receiving cavity 11 and the second receiving cavity 12 are arranged along the second direction, and the thickness of the first receiving cavity 11 along the first direction is less than the thickness of the second receiving cavity 12; Figure 2 As shown, one side end surface of the first receiving cavity 11 and the second receiving cavity 12 are flush.

[0034] The adsorption component is arranged in the first storage cavity 11. The number of adsorption components can be set according to design requirements. It includes an adsorption port 13 for installing a suction cup 60. The adsorption port 13 is connected to the storage space. The number of adsorption ports 13 can be set according to actual needs. Generally speaking, the number of adsorption ports 13 corresponds one-to-one to the adsorption components. In this embodiment, two adsorption ports 13 are taken as an example.

[0035] The air source component is disposed in the second receiving chamber 12 and is connected to the adsorption component. The air source component is used to cooperate with the adsorption component to form a negative pressure or a positive pressure at the adsorption port 13. The same air source component can be connected to multiple adsorption components, and any number of adsorption components can be independently controlled through drive control to meet different adsorption requirements. In other embodiments, the air source component can also include multiple pump bodies to control different numbers of adsorption components respectively to improve the adsorption efficiency.

[0036] like Figure 7 As shown, the air inlet direction of the suction port 13 is perpendicular to the air inlet direction of the air source component. Figure 7 The figure shows the flow direction of gas in working state.

[0037] When used, it also includes a terminal adsorption piece, which is arranged in the accommodation space and communicated with the adsorption port 13. In a preferred embodiment of the present application, the terminal adsorption piece is a square box structure, which includes an adsorption surface, and the adsorption surface is flush with the side of the second receiving cavity 12 away from the opening surface or protrudes from the side of the second receiving cavity 12 away from the opening surface, that is, after the housing 10 and the terminal adsorption piece are assembled, the whole presents a square box structure.

[0038] Furthermore, along the adsorption direction, the first end surface of the first receiving cavity 11 is flush with the first end surface of the second receiving cavity 12 , and the second end surface of the first receiving cavity 11 is staggered with the second end surface of the second receiving cavity 12 .

[0039] Specifically, the suction port 13 is opened on the second end surface.

[0040] This arrangement allows the vacuum pump 20 and the adsorption assembly to be arranged in the same plane without stacking, thereby greatly reducing the height of the adsorption device. Figure 7It can be seen that due to the different thicknesses of the first storage cavity 11 and the second storage cavity 12, there will be a height difference between the two. Since the suction cup 60 itself also has a certain spatial dimension, the height difference between the first storage cavity 11 and the second storage cavity 12 can accommodate the suction cup 60, so that after the suction cup 60 is installed, the height dimension of the entire adsorption device will not increase or only increase a smaller dimension smaller than the height of the suction cup 60, so that the adsorption device can be designed to be miniaturized and flat.

[0041] Embodiment 2:

[0042] On the basis of the first embodiment, in this embodiment, the adsorption component includes an air chamber 30, a solenoid valve 40 and at least three air pipe ports 50. In this embodiment, three air pipe ports 50 are used as an example. The air pipe ports 50 are connected to the air chamber 30, and the solenoid valve 40 is used to control the opening and closing of the air pipe ports 50; wherein, one air pipe port 50 is connected to the adsorption port 13, and is used to connect the adsorption port 13 and the air chamber 30; one air pipe port 50 is connected to the air source component, and is used to connect the air source component and the air chamber 30; and one air pipe port 50 is vacant and is used to release gas.

[0043] Specifically, Figure 4 As shown, the adsorption assembly includes an air chamber 30, a solenoid valve 40 and three air pipe ports 50 arranged along the second direction. A plurality of air chambers connected to each other are arranged in the air chamber 30. The air pipe ports 50 are connected to the air chambers. The solenoid valve 40 is attached to one side of the air chamber 30 and connected to the air chamber. The opening and closing of the air pipe ports 50 are controlled by the air chambers. The three air pipe ports 50 are respectively arranged on three adjacent end faces of the air chamber 30, one of which faces the air source assembly, and the other two air pipe ports 50 are distributed on the side of the air chamber 30 away from the solenoid valve 40. One air pipe port 50 is respectively arranged on the opposite side end faces of the air chamber 30, and the other air pipe port 50 faces the air source assembly. The air pipe port 50 is connected to the vacuum pump 20 through a pipeline 51.

[0044] This arrangement enables the three air pipe openings 50 to be distributed on different end surfaces respectively. When the pipeline 51 is installed, spatial interference is less likely to occur, which facilitates the installation of the pipeline 51.

[0045] Embodiment three:

[0046] In the second embodiment, since the three air pipe openings 50 are arranged on different end faces respectively, when the air chamber 30 is processed, it is necessary to process and open connection holes on different end faces respectively. During processing, the air chamber 30 needs to be turned over, which results in more processing steps and is not conducive to reducing processing costs.

[0047] Therefore, in this embodiment, Figure 5As shown, there are three air pipe openings 50 and any two air pipe openings 50 are distributed on the same side of the air chamber 30. When the two air pipe openings 50 are distributed on the same end surface, the connection holes of the two air pipe openings 50 can be processed at the same time under one clamping, without turning the workpiece during the processing, thereby improving the processing efficiency.

[0048] Embodiment 4:

[0049] On the basis of the second or third embodiment, Figure 6 As shown, there is at least one adsorption assembly, and the adsorption assembly includes three air pipe ports 50. At least two air pipe ports 50 in the adsorption assembly are located on the same side of the air chamber 30, and the two adsorption assemblies in a pair of adsorption assemblies are arranged opposite to each other on the same side. Since the pair of adsorption assemblies are arranged opposite to each other, the size of the adsorption assembly after installation can be reduced, which is conducive to the miniaturization of the adsorption device.

[0050] Embodiment five:

[0051] In the third or fourth embodiment, if Figure 5 , Figure 6 and Figure 3 As shown, when at least two air pipe openings 50 are distributed on any side of the air chamber 30, the axis lines of the two adjacent air pipe openings 50 on this side are tilted and turned in opposite directions.

[0052] like Figure 3 As shown, when two adjacent air pipe ports 50 are arranged horizontally, the pipes 51 will interfere with each other. Since the pipes 51 have a bending radius, at least the space required for the bending radius of the pipes 51 is reserved between the two adjacent air pipe ports 50, which will cause the size of the final adsorption device to become larger. However, by tilting and flipping the axis of the air pipe ports 50 in the opposite direction, the pipes 51 can be stacked in space (stacked up and down), thereby reducing the space required between the air pipe ports 50, which is conducive to the miniaturization design of the adsorption device.

[0053] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
