[0039] The specific implementation of the present invention is described in detail below. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0040] In the present invention, unless otherwise stated, the directional words such as "upper" and "lower" usually refer to the orientation in the assembled state. "Inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0042] The utility model provides an electric suction cup, such as Figure 1-Figure 5 As shown, it includes a rubber disc 10, a handle 20, a negative pressure forming component, a negative pressure releasing component, an energy supply module 60 and a controller. The rubber disc 10 is used to be adsorbed on the adsorbed object, and its adsorption surface can form a closed space with the adsorbed object. The handle 20 is arranged on the rubber disc 10. The negative pressure forming component is used to automatically form a negative pressure environment between the rubber disc 10 and the adsorbed object, so that the rubber disc 10 is adsorbed on the adsorbed object. The negative pressure releasing component is used to release the negative pressure environment formed between the rubber disc 10 and the adsorbed object. The energy supply module 60 is used to supply energy to the negative pressure forming component and / or the negative pressure releasing component. The controller is used to control the start and stop of the negative pressure vacuum pump 42, and to control the working state of the negative pressure forming component and / or the negative pressure releasing component.

[0043] Through the above technical solution, based on the setting of the negative pressure forming component, a negative pressure environment can be automatically formed with the adsorption object, so that the adhesive disc is adsorbed on the adsorption object. This technical solution solves the problem of inconvenient operation of the suction cup in the prior art.

[0044] In an optional specific embodiment, the negative pressure forming component includes a negative pressure vacuum pump 42, an exhaust pipe 41 and a one-way valve. The negative pressure vacuum pump 42 is used to extract the air in the enclosed space so that the enclosed space forms a negative pressure environment. One end of the exhaust pipe 41 is connected to the negative pressure vacuum pump 42, and the other end is connected to the enclosed space. The one-way valve is arranged on the exhaust pipe 41, which only allows the gas in the enclosed space to flow toward the negative pressure vacuum pump 42. The controller is used to control the start and stop of the negative pressure vacuum pump 42. The controller can control the negative pressure vacuum pump 42 to stop working according to the change in the current of the negative pressure vacuum pump 42 within the time t1 or the change in the negative pressure value in the enclosed space within the time t1.

[0045] For example, when the change in the current of the negative pressure vacuum pump 42 within time t1 is less than Δa, the negative pressure vacuum pump 42 is controlled to stop working. When the negative pressure value in the confined space changes by Δp within time t1, the negative pressure vacuum pump 42 is controlled to stop working.

[0046] Compared with the prior art, this embodiment omits the air pressure sensor for detecting the negative pressure value in the enclosed space. In the prior art, the negative pressure value in the enclosed space is usually detected by a pressure sensor, and when the negative pressure value reaches a predetermined value, a signal is transmitted to the controller, and the controller controls the negative pressure pump to stop working.

[0047] Under ideal conditions, after the confined space is evacuated, the negative pressure environment can be maintained until the handling work is completed. However, in reality, since it is difficult to achieve absolute sealing, the negative pressure environment will gradually be destroyed. At the same time, after the suction cup is on the adsorbed object, if the vacuum environment is destroyed, the suction cup will fall off. In the prior art, the process of vacuum environment destruction is difficult to capture manually, and the operator can only realize that the suction cup has fallen off when the suction cup actually falls off. In other words, the existing vacuum suction cup device lacks the function of identifying faults, and the identification of faults mainly relies on the experience of the staff or the consequences after the fault occurs. However, there is a large uncertainty in judging the fault based on the experience of the staff; there is a certain lag in identifying the existence of the fault based on the consequences after the fault occurs, which may bring safety hazards.

[0048] Based on this, further, this specific method adds an air pressure sensor on the basis of the aforementioned technical solution. Based on the setting of the air pressure sensor, when the negative pressure value in the enclosed space is lower than the first predetermined value, the negative pressure pump is started to evacuate air, and when the change in the current of the negative pressure vacuum pump 42 within the time t1 is less than Δa, the negative pressure pump stops working. In this way, the negative pressure value in the enclosed space can always be kept above the first predetermined value, ensuring that the rubber disc 10 can be adsorbed on the adsorption object. In other words, even if the electric suction cup cannot be absolutely sealed, it can ensure that the rubber disc 10 has a considerable degree of adsorption force.

[0049] In the prior art, the start and stop of the negative pressure vacuum pump 42 depends on the pressure value signal obtained by the pressure sensor. When the pressure value obtained by the pressure sensor reaches a first predetermined value, the negative pressure vacuum pump 42 stops working, and when the pressure value obtained by the negative pressure vacuum pump 42 is lower than a second predetermined value, the negative pressure vacuum pump 42 starts. Such a setting can ensure that the negative pressure value in the confined space is always maintained between the first predetermined value and the second predetermined value, ensuring that the suction cup can be adsorbed on the adsorption object and can bear a certain pulling force.

[0050] The defect of the prior art is that it cannot adapt to different negative pressure vacuum pumps. Specifically, when the electric suction cup replaces the negative pressure vacuum pump, and other conditions remain unchanged, the negative pressure environment of the confined space may never reach the first predetermined value, and the negative pressure vacuum pump will never stop working. The reason is that the stop of the negative pressure vacuum pump is determined by the air pressure sensor. For example, if the second predetermined value is set to a, and the vacuum pumping capacity of the negative pressure vacuum pump cannot reach a, the negative pressure vacuum pump will not stop working. By detecting the "change in the negative pressure value within t1 time" and the "change in the current of the negative pressure vacuum pump within t1 time" in the confined space as the stop signal for controlling the negative pressure vacuum pump, the electric suction cup can be adapted to different models of negative pressure vacuum pumps.

[0051] In addition, the change in the negative pressure value in the enclosed space within time t1 that is less than a% of the maximum load of the negative pressure vacuum pump 42 can be used as a signal to control the negative pressure vacuum pump 42 to stop working. The principle is similar to that of the above two control methods.

[0052] Furthermore, the negative pressure relief component includes a deflation ear 30 disposed on the circumferential side wall of the rubber disc 10. After a negative pressure environment is formed in the enclosed space, if the electric suction cup needs to be moved to another position, the negative pressure environment needs to be destroyed. At this time, the deflation ear 30 can be pulled to cause the enclosed space to deflate and destroy the negative pressure environment.

[0053] In an optional specific embodiment, the negative pressure relief component adopts a manual pressure relief component, which includes a first air relief channel, a sealing plug and an elastic wrench. One end of the first air relief channel is connected to the exhaust pipe 41, and the other end is provided with an air relief port. The sealing plug is used to seal the air relief port. The elastic wrench switches the state of the sealing plug opening and closing the air relief port. When the elastic wrench is not subjected to external force, the sealing plug closes the air relief port. The elastic wrench includes a wrench and a spring.

[0054] The configuration of the manual pressure relief component can make the electric suction cup more convenient when transferring the adsorption position. Specifically, when the adsorption position needs to be changed, hold the handle 20, press the elastic wrench with the thumb to destroy the negative pressure environment in the enclosed space, lift the electric suction cup, and under the action of the pressure sensor, the negative pressure vacuum pump 42 is started, and then the rubber disc 10 of the electric suction cup is attached to the adsorption object to form a enclosed space with the new adsorption position, and a negative pressure environment is formed under the action of the negative pressure vacuum pump 42.

[0055] In an optional specific embodiment, the negative pressure relief component includes: an air leak ear, a second air leak channel and a solenoid valve. The air leak ear is arranged on the circumferential side wall of the rubber disc 10. One end of the second air leak channel is connected to the exhaust pipe 41. The solenoid valve is arranged on the second air leak channel and is electrically connected to the controller, and is used to destroy the negative pressure environment formed between the rubber disc 10 and the adsorption object. By controlling the solenoid valve to open by the controller, the external air can enter the enclosed space along the second air leak channel and the exhaust pipe to destroy the negative pressure environment.

[0056] In an optional specific embodiment, the bottom of the adhesive disc 10 is provided with an annular groove 11 whose diameter gradually increases from the center of the adhesive disc 10 to the outside and a linear groove 12 connecting each of the annular grooves 11. The adsorption surface of the adhesive disc 10 is provided with an air extraction hole 13, which is arranged in the annular groove 11 and / or the linear groove 12 and is connected to the air extraction pipe 41.

[0057] Furthermore, the energy supply module includes a rechargeable battery, and the side wall of the handle is provided with a mounting groove adapted to the battery.

[0058] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0059] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0060] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
