Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0038] At present, the application of power batteries is more and more extensive. Power batteries are not only applied to energy storage power supply systems such as hydroelectric, thermal, wind and solar power stations, but also widely applied to electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also increasing.

[0039] The adhesive application process described in this application is a crucial part of the production of electrode components for power batteries. In related technologies, adhesive application equipment uses vacuum suction cups to adhere heat insulation pads and insulating covers to the surface of the battery cell. However, because both the heat insulation pads and insulating covers are coated with adhesive on both sides, a significant adhesive force is generated between them and the suction cups. During application, when the air blows air into the suction cups to break the vacuum, a portion of the airflow is diverted to the suction line to release pressure. This results in insufficient airflow at the suction cups to break the vacuum, leading to insufficient thrust and potentially causing the heat insulation pads and insulating covers to fail to detach from the suction cups or to be applied crookedly, ultimately affecting the quality of the battery cell assembly.

[0040] Therefore, this application proposes a material handling device. By installing a control valve in the first air path used for vacuuming, the valve opens when the suction cup is in the adsorption state to smoothly adsorb objects, and closes when the suction cup is in the release state. This prevents the airflow in the second air path used for vacuum breaking from being diverted into the first air path and depressurized, thus ensuring the airflow in the second air path. This increases the blowing pressure at the suction cup for vacuum breaking, counteracting the adhesive force between the heat insulation pad or insulating cover and the suction cup, achieving rapid separation of the heat insulation pad or insulating cover from the suction cup, and improving adhesive application accuracy. The structure of this material handling device will be described below by way of embodiments.

[0041] like Figure 1 and Figure 2 As shown, the material handling device 100 includes a suction cup 10 and an air circuit system.

[0042] The air path system includes a first air path 21, a second air path 22, an air source component 28, and a switching valve 29. Both the first air path 21 and the second air path 22 are connected to the airflow channel of the suction cup 10. The first air path 21 is configured to create a vacuum negative pressure at the suction cup 10, and the second air path 22 is configured to blow air at the suction cup 10. The first air path 21 and the second air path 22 are connected to the air source component 28 through the switching valve 29. The switching valve 29 is configured to connect the air source component 28 to the first air path 21, or connect the air source component 28 to the second air path 22. The first air path 21 is provided with a control valve 23, which is configured to open in the adsorption state and close in the release state.

[0043] The suction cup 10 is used to adsorb and release the object to be attached. The suction cup 10 has airflow channels communicating with the first air passage 21 and the second air passage 22. When the first air passage 21 is evacuated, a vacuum negative pressure is created on the adsorption surface of the suction cup 10 through the airflow channels to adsorb the object. When the second air passage 22 is blew air, air is blown onto the adsorption surface of the suction cup 10 through the airflow channels to break the adhesive force between the suction cup 10 and the object to be attached, thus releasing the object. Optionally, the suction cup 10 can be made of metal or plastic. The adsorption surface of the suction cup 10 can be circular, square, rectangular, or some other shape.

[0044] The first air path 21 is in communication with the air flow channel of the suction cup 10, and can form a vacuum negative pressure on the suction surface of the suction cup 10. It can be understood that the first air path 21 corresponds to an air extraction path, and can be realized by a vacuum generator 24 or other suction driving components. Alternatively, the first air path 21 can be connected to a separate air source assembly 28, or can share the air source assembly 28 with the second air path 22. The first air path 21 can be directly connected to the air flow channel of the suction cup 10, such as direct plug-in fitting, or can be indirectly connected, such as through a pipeline.

[0045] The second air path 22 is in communication with the air flow channel of the suction cup 10, and can blow air to the suction surface of the suction cup 10 to destroy the vacuum between the suction surface and the object to be pasted. It can be understood that the second air path 22 is an air blowing path, one end of which is connected to the air source assembly 28, and the other end is in communication with the air flow channel of the suction cup 10. Alternatively, the second air path 22 can be connected to a separate air source assembly 28, or can share the air source assembly 28 with the first air path 21. The second air path 22 can be directly connected to the air flow channel of the suction cup 10, such as direct plug-in fitting, or can be indirectly connected, such as through a pipeline.

[0046] The air source assembly 28 can provide compressed air, and the air source assembly 28 can be a gas source three-in-one piece integrated with an air filter, a pressure reducing valve, and an oil atomizer. The switching valve 29 can be an electromagnetic valve, a hydraulic valve, or a pneumatic valve. Alternatively, the switching valve 29 can be a two-position three-way valve.

[0047] The first air path 21 and the second air path 22 are in communication with the air source assembly 28 through the switching valve 29. It can be understood that the first air path 21 and the second air path 22 realize the switching between the suction state and the release state through the switching valve 29. When the object to be pasted needs to be suctioned, the switching valve 29 connects the first air path 21 to the air source assembly 28, while blocking the second air path 22 from the air source assembly 28. At this time, the control valve 23 is opened, and the compressed air generated by the air source assembly 28 flows to the vacuum generator 24 to generate negative pressure, and then generates suction force at the suction cup 10 to suction the object to be pasted. When the object to be pasted needs to be released, the switching valve 29 connects the second air path 22 to the air source assembly 28, while blocking the first air path 21 from the air source assembly 28. At this time, the control valve 23 is closed, and the compressed air generated by the air source assembly 28 directly flows to the suction cup 10 to blow air outward, so as to destroy the vacuum and separate the object to be pasted from the suction cup 10. Such a design can simplify the structure, save the number of components, and reduce the cost.

[0048] It should be noted that the working of the first gas path 21 and the second gas path 22 is not simultaneous, that is, when the first gas path 21 works, the second gas path 22 stops; when the second gas path 22 works, the first gas path 21 stops. Since the first gas path 21 and the second gas path 22 are both in communication with the air flow channel of the suction cup 10, the first gas path 21 and the second gas path 22 can be in communication at the air flow channel of the suction cup 10, or can be in communication at the pipeline connected with the air flow channel of the suction cup 10, which can cause the air flow in the second gas path 22 to be partially diverted to the first gas path 21 when the second gas path 22 blows air to the suction surface of the suction cup 10 to release the object to be pasted, and then the blowing pressure of the broken vacuum can be insufficient. Based on this, the control valve 23 is arranged on the first gas path 21, which can be opened in the adsorption state to smoothly adsorb the object to be pasted, and closed in the release state, that is, the control valve 23 can close the first gas path 21 when the second gas path 22 blows air to the suction surface, preventing the air flow in the second gas path 22 from flowing into the first gas path 21 to release pressure, increasing the blowing pressure of the broken vacuum at the suction cup 10, and offsetting the adhesion between the object to be pasted and the suction cup 10. Optionally, the control valve 23 can be a solenoid valve, a hydraulic valve, a pneumatic valve or other types of valve structures, etc. Optionally, the control valve 23 can be a one-in-one-out valve structure, or can be a multi-in multi-out valve structure.

[0049] In summary, in the material taking device 100 of the technical scheme of the present application, the gas path system includes the first gas path 21 for vacuum pumping and the second gas path 22 for blowing air to break the vacuum, so that the suction cup 10 has an adsorption state of vacuum pumping and a release state of blowing air to break the vacuum. By arranging the control valve 23 on the first gas path 21, the control valve 23 is opened when the suction cup 10 is in the adsorption state to smoothly adsorb the object, and the control valve 23 is closed when the suction cup 10 is in the release state, so that the air flow in the second gas path 22 cannot be diverted to the first gas path 21 to release pressure, thereby ensuring the air flow in the second gas path 22, increasing the blowing pressure of the broken vacuum at the suction cup 10, and offsetting the adhesion between the object such as the heat insulation pad or the insulating cover and the suction cup 10. The object such as the heat insulation pad or the insulating cover and the suction cup 10 are quickly separated, the glue pasting precision is improved, and the product yield is improved.

[0050] In an embodiment of the present application, the control valve 23 is a solenoid valve.

[0051] Such a design uses a solenoid valve as a control switch in the gas path, achieving the purpose of completely autonomous control of the gas path and avoiding pressure release of the air flow when breaking the vacuum.

[0052] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the first gas path 21 is provided with a vacuum generator 24, and the control valve 23 is arranged between the vacuum generator 24 and the suction cup 10.

[0053] The vacuum generator 24 is used to generate negative pressure to suck the gas in the first gas path 21 and the gas flow channel of the suction cup 10, so that the suction surface of the suction cup 10 can smoothly suck the object to be pasted. It can be understood that the vacuum generator 24 has a compressed air flow channel and a suction flow channel, the compressed air flow channel is communicated with the air source assembly 28 and the exhaust cavity, and the suction flow channel is used to communicate with the suction cup 10. By the high-speed flow of compressed air, a negative pressure vacuum is generated at the suction flow channel by using Bernoulli's principle, so as to realize the suction and control of the fluid or object at the suction cup 10.

[0054] When it is necessary to paste the object to be pasted, a part of the gas in the second gas path 22 may flow to the exhaust of the vacuum generator 24. Therefore, in the embodiment, the control valve 23 is arranged at a position between the vacuum generator 24 and the suction cup 10, that is, the control valve 23 is arranged at the negative pressure side of the vacuum generator 24. When it is necessary to paste the object to be pasted, the control valve 23 is closed to block the path of the gas flow in the second gas path 22 to the vacuum generator 24, so as to avoid the gas flow in the second gas path 22 to exhaust at the vacuum generator 24. Therefore, the blowing strength of the vacuum at the suction cup 10 can be ensured, the object such as the heat insulation pad or the insulating cover can be quickly separated from the suction cup 10, and the pasting efficiency is improved.

[0055] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the gas path system further comprises a first pipe 251 and a three-way joint 252, the first pipe 251 is communicated with the suction cup 10 and one interface of the three-way joint 252, the first gas path 21 and the second gas path 22 are respectively communicated with the other two interfaces of the three-way joint 252; the control valve 23 is arranged between the vacuum generator 24 and the three-way joint 252.

[0056] In the embodiment, the three-way joint 252 is a joint structure with three interfaces, one interface is communicated with the suction cup 10 through the first pipe 251, the other interface is communicated with the first gas path 21, and the third interface is communicated with the second gas path 22. Such design can simplify the pipe connection and improve the pipe connection efficiency.

[0057] The control valve 23 is arranged between the vacuum generator 24 and the three-way joint 252. When the object to be attached needs to be adsorbed, the control valve 23 is opened, the vacuum generator 24 generates negative pressure, and the air flow at the suction cup 10 is sequentially sucked to the vacuum generator 24 through the first pipeline 251, the three-way joint 252 and the control valve 23, so that the suction cup 10 can generate suction force to adsorb the object to be attached. When the object to be attached needs to be released, the vacuum generator 24 and the control valve 23 are closed, and the air flow in the second air path 22 directly flows to the adsorption surface of the suction cup 10 through the three-way joint 252 and the first pipeline 251 to destroy the vacuum, and will not flow from the three-way joint 252 to the vacuum generator 24. Therefore, the blowing strength of the suction cup 10 can be increased to offset the adhesion between the object to be attached and the suction cup 10, so that the object such as the thermal insulation pad or the insulating cover can be quickly separated from the suction cup 10.

[0058] Referring to Figure 1 and Figure 2 In an embodiment of the present application, the air path system further comprises a negative pressure gauge 26 arranged in the first air path 21, and the negative pressure gauge 26 is located between the control valve 23 and the vacuum generator 24.

[0059] In the embodiment, the negative pressure gauge 26 is a structure for detecting and displaying the negative pressure data in the first air path 21. Alternatively, the negative pressure gauge 26 is a digital negative pressure gauge.

[0060] Such a design can avoid damage to the pressure tube in the gauge caused by repeated action of positive pressure and negative pressure of the air flow, reduce faults, and prolong the service life, by arranging the negative pressure gauge 26 between the control valve 23 and the vacuum generator 24.

[0061] Referring to Figure 1 and Figure 2 In an embodiment of the present application, the second air path 22 is provided with a flow regulating valve 27.

[0062] Such a design can adjust the air flow for destroying the vacuum according to the actual pressure for destroying the vacuum, by additionally arranging the flow regulating valve 27 on the second air path 22. It can be understood that the flow regulating valve 27 is arranged in the pipe section on the side of the three-way joint 252 away from the suction cup 10, so that the air flow in the second air path 22 can be accurately controlled.

[0063] Referring to Figure 3 In an embodiment of the present application, the air path system comprises a plurality of first air paths 21 and a plurality of second air paths 22, the plurality of first air paths 21 are connected in parallel and connected to one outlet end of a switching valve 29, the plurality of second air paths 22 are connected in parallel and connected to another outlet end of the switching valve 29, and each first air path 21 is provided with a control valve 23.

[0064] In the embodiment, the plurality of first gas paths 21 are connected in parallel and then connected with one outlet end of the switching valve 29, the plurality of second gas paths 22 are connected in parallel and then connected with another outlet end of the switching valve 29, each first gas path 21 corresponds to one second gas path 22, so that the plurality of first gas paths 21 and the plurality of second gas paths 22 share the same gas source assembly 28 and the same switching valve 29, in this way, the plurality of objects can be simultaneously pasted, the production rhythm is accelerated, and the production efficiency is improved. Optionally, the control valve 23, the vacuum generator 24 and the negative pressure gauge 26 can be arranged on each first gas path 21. Optionally, the flow regulating valve 27 is arranged on each second gas path 22.

[0066] Such a design can further increase the number of simultaneous pasting, further accelerate the production rhythm, and improve the production efficiency. Optionally, the at least two suction cups 10 can be communicated with the first pipeline 251 through the multi-way joint, and then communicated with the first gas path 21 and the second gas path 22 through the three-way joint 252.
