Description

Technical Field

[0001] The invention belongs to the technical field of vacuum suction cups, and in particular relates to a novel suction cup matrix. Background Art

[0002] With the substantial increase in logistics packages, robotics technology is also developing rapidly. Most traditional suction cups are vacuum suction cups, which need to be connected to an air pump and have multiple complex structures such as a vacuum generator and connecting pipes. Traditional suction cups are usually designed for objects of specific shapes and sizes. For objects with complex shapes or varying sizes, their adsorption effect is not ideal. When adsorbing light and small objects, it is also easy to adsorb by mistake, that is, there is a problem of adsorbing nearby objects together. Moreover, traditional vacuum suction cups are connected to equipment such as air pumps through connecting pipes, and this method is also prone to air leakage. Summary of the invention

[0003] The object of the present invention is to provide a novel suction cup matrix to solve at least one of the above problems in the prior art.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A novel suction cup matrix comprises a device shell, on which are mounted a plurality of suction cup assemblies which are individually controlled and arranged in a rectangular array, each suction cup assembly comprising a suction cup, a vacuum pump and a solenoid valve, the suction cup being mounted at the lower end of the device shell, the vacuum pump and the solenoid valve being mounted inside the device shell, and the upper end of the suction cup being connected to the inlet of the vacuum pump and the interface of the solenoid valve, and the interface of the solenoid valve being connected to the outside of the device shell; a control circuit board is also mounted inside the device shell, and the vacuum pump and the solenoid valve are both electrically connected to the control circuit board.

[0006] As a preferred technical solution in the present invention, the device shell includes a device upper shell and a suction cup base, all suction cups are arranged in a rectangular array at the lower end of the suction cup base, the control circuit board and all vacuum pumps and solenoid valves are installed at the upper end of the suction cup base, the device upper shell cover is arranged outside the control circuit board and all vacuum pumps and solenoid valves, and the device upper shell is connected to the suction cup base.

[0007] As a preferred technical solution in the present invention, the novel suction cup matrix further includes a visual module, and the visual module is electrically connected to the control circuit board.

[0008] Beneficial effect: The suction cup of the present invention is directly connected to the vacuum pump and the solenoid valve, which reduces the risk of air leakage. When adsorbing items, any suction cup assembly can be controlled separately to start working. The suction cup that needs to work cooperates with the vacuum pump to start exhausting. The solenoid valve moves tightly and closes, and is in a normally closed state. The suction cup generates adsorption force to adsorb items. When adsorption is not needed, the matching vacuum pump of the corresponding working suction cup stops working, the solenoid valve is relaxed, and converted to a normally open state. The solenoid valve opens to allow external air to enter the suction cup, and the suction cup loses adsorption force and puts down the item. The suction cup assembly of the present invention adopts the form of electric control, which is simpler than the structure of the traditional suction cup. In the actual operation process, a single suction cup assembly can be controlled separately, thereby realizing the operation of a single hole or multiple combined holes. The same suction cup can adsorb workpieces of any size and shape, with high accuracy, and can avoid the occurrence of misabsorption. The whole process forms a negative pressure by reducing the local air pressure, thereby achieving a strong adsorption force. It can be flexibly allocated for objects of different weights, and the grasping rate is greatly improved, which improves the operational flexibility and adaptability.

[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0014] Example:

[0015] like Figure 1-Figure 3 As shown, this embodiment provides a novel suction cup matrix, including a device housing 1, on which a plurality of suction cup assemblies that are individually controlled and arranged in a rectangular array are mounted, such as Figure 1 There are three rows and four columns, a total of twelve suction cup assemblies (it should be noted here that Figure 1 This is just an example, and there is no specific limit on the number in practice, and there can be more than twelve suction cup assemblies). Each suction cup assembly includes a suction cup 2, a vacuum pump 3 and a solenoid valve 4. The suction cup 2 is installed at the lower end of the device housing 1, and the vacuum pump 3 and the solenoid valve 4 are installed inside the device housing 1, and the upper end of the suction cup 2 is connected to the inlet of the vacuum pump 3 and the interface of the solenoid valve 4, which reduces the connecting pipelines and thus reduces the risk of air leakage. The interface of the solenoid valve 4 is connected to the outside of the device housing 1 through a pipeline. Preferably, the solenoid valve 4 is a two-position, three-way normally open solenoid valve, and the upper end of the suction cup is connected to both the solenoid valve interface 1 and the interface 2, and the solenoid valve interface 2 is connected to the external atmospheric pressure. When the suction cup does not need to be adsorbed, the solenoid valve is normally open, the entire suction cup is consistent with the external atmospheric pressure, and the suction cup has no adsorption force.

[0016] A control circuit board 5 is also installed inside the device housing 1. The vacuum pump 3 and the solenoid valve 4 are electrically connected to the control circuit board 5, and the vacuum pump 3 and the solenoid valve 4 can be controlled by the control circuit board 5. When it is actually necessary to adsorb items, the control circuit board 5 can independently control any suction cup component to start working, and the suction cup 2 that needs to work cooperates with the vacuum pump 3 to start pumping air. The solenoid valve 4 moves and closes tightly, and is in a normally closed state. The suction cup 2 generates adsorption force to adsorb items. When adsorption is not needed, the matching vacuum pump 3 of the corresponding working suction cup 2 stops working, and the solenoid valve 4 relaxes and switches to a normally open state. The solenoid valve 4 opens to allow external air to enter the suction cup 2, and the suction cup 2 loses its adsorption force and puts down the item. The suction cup assembly of the present invention adopts an electric control form, which is simpler in structure than traditional suction cups. During actual operation, a single suction cup assembly can be controlled individually to achieve single-hole or multiple combined-hole operation. The same suction cup can adsorb workpieces of any size and shape with high accuracy, and can avoid accidental suction. The entire process forms a negative pressure by reducing the local air pressure, thereby achieving a strong adsorption force. It can be flexibly adjusted for objects of different weights, greatly improving the grasping rate, and improving operational flexibility and adaptability.

[0017] As a preferred implementation scheme in this embodiment, it needs to be further explained that the device housing 1 includes a device upper shell 101 and a suction cup base 102, all suction cups 2 are arranged in a rectangular array at the lower end of the suction cup base 102, the control circuit board 5 and all vacuum pumps 3 and solenoid valves 4 are installed at the upper end of the suction cup base 102, the device upper shell 101 covers the control circuit board 5 and all vacuum pumps 3 and solenoid valves 4, and the device upper shell 101 is connected to the suction cup base 102, so as to protect the internal structure and facilitate the connection with a robot or a crane through the device upper shell 101, thereby improving the flexibility of the new suction cup matrix.

[0018] As a preferred implementation scheme in this embodiment, it needs to be further explained that the novel suction cup matrix also includes a visual module, which is electrically connected to the control circuit board 5. The visual module can accurately identify the target object and accurately locate it, and then feedback the signal to the control circuit board 5. The control circuit board 5 controls the operation of the suction cup assembly according to the feedback signal, and at the same time ensures the accuracy of the suction cup when adsorbing objects. It should be noted that the visual module is a separate module, which can be integrated on the device housing 1 or in other surrounding locations. It can be set according to actual conditions, and this embodiment does not make specific limitations.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
