[0040] When in use, for the operation of sucking two pieces of materials at a time, any one of the two groups of suction cups can be activated first according to the needs. Here, the right group of suction cups 31 is started first as an example for explanation. The operation process is: the vacuum pump 4 is working, the air outlet 513 of the three-way solenoid valve 51 is closed, the exhaust port 512 and the air inlet 511 of the three-way solenoid valve 51 are opened, the exhaust port 512 and the air inlet 511 are connected, and the air between the suction cup 31 and the material passes through the fluid channel a61, the air inlet 511 of the three-way solenoid valve 51, the exhaust port 512 of the three-way solenoid valve 51, and the fluid channel c63 in turn, enters the vacuum pump suction hole 41, and then is exhausted by the vacuum pump exhaust hole 42 to complete the adsorption operation of one piece of material. At this time, the air inlet 521, the exhaust port 522, and the air outlet 523 of the three-way solenoid valve 2 52 are all in a closed state; Then the air outlet 513, exhaust port 512 and air inlet 511 of the three-way solenoid valve 1 51 are closed, the exhaust port 522 and air inlet 521 of the three-way solenoid valve 2 52 are opened, the air outlet 523 is closed, the exhaust port 522 and air inlet 521 of the three-way solenoid valve 2 52 are connected, and the air between the left group of suction cups 31 and the material passes through the fluid channel b62, the air inlet 521 of the three-way solenoid valve 2 52, the exhaust port 522 of the three-way solenoid valve 2 52, and the fluid channel c63 in turn, and enters the vacuum pump suction hole 41, and then the vacuum pump exhaust hole 42 completes the adsorption operation of another material, and the entire adsorption operation is completed; when the two materials at the same position are adsorbed simultaneously, the above-mentioned three-way solenoid valve 1 51 and the three-way solenoid valve 2 52 are started at the same time to synchronously complete the above-mentioned adsorption operation, thereby improving the operation efficiency.

[0041] When placing materials, two materials can be placed at the same time according to the required scene, or the same material can be placed in different positions in sequence. When placing materials at the same time, the exhaust port 513 of the three-way solenoid valve 1 51 and the exhaust port 522 of the three-way solenoid valve 2 52 are closed, the air inlet 511 and the air outlet 513 of the three-way solenoid valve 1 51, and the air inlet 521 and the air outlet 523 of the three-way solenoid valve 2 52 are opened, the air inlet 511 and the air outlet 513 of the three-way solenoid valve 1 51 are connected, the air inlet 521 and the air outlet 523 of the three-way solenoid valve 2 52 are connected, and the external air is introduced from the three-way solenoid valve 1 The air enters through the air outlet 513 of the three-way solenoid valve 51, passes through the air inlet 511 of the three-way solenoid valve 1 51, the fluid channel a61, and the internal airway port on the right side of the adsorption panel 2 connected to the suction cup port of the adapter plate 3, and finally reaches the suction cup port.

[0042] When the same material is placed in different positions, any one of the two groups of suction cups 31 can be operated first according to the priority of placement. Here, the right side suction cup 31 group is taken as an example to illustrate the specific process. First, the air inlet 521, the exhaust port 522, and the air outlet 523 of the three-way solenoid valve 2 52 are closed, the exhaust port 512 of the three-way solenoid valve 1 51 is closed, the air inlet 511 and the air outlet 513 of the three-way solenoid valve 1 51 are opened, the air inlet 511 and the air outlet 513 of the three-way solenoid valve 1 51 are connected, and the external air enters from the air outlet 513 of the three-way solenoid valve 1 51, and passes through the air inlet 511 of the three-way solenoid valve 1 51, the fluid channel a61, and the suction cup port of the adapter plate 3 connected to the right side of the adsorption panel 2 in turn.

Then the air inlet 511, the exhaust port 512, and the air outlet 513 of the three-way solenoid valve 51 are closed, the air inlet 521 and the air outlet 523 of the three-way solenoid valve 52 are opened, and the exhaust port 522 is closed. The air inlet 521 and the air outlet 523 of the three-way solenoid valve 52 are connected, and the external air enters from the air outlet 523 of the three-way solenoid valve 52, and passes through the air inlet 521 of the three-way solenoid valve 52, the fluid channel b62, and the internal airway port of the suction cup port of the adapter plate 3 on the left side of the adsorption panel 2 in turn, and finally reaches the vacuum at a group of suction cups 31 on the left side, and the material is placed on the left side. At this point, the entire material placement operation is completed.

[0043] When adsorbing the stacked materials with vacuum, first activate one set of suction cups 31 to suck up one side of the materials, and then activate another set of suction cups 31 after the vacuum between the adsorbed materials and the next layer of materials is broken. The two sets of suction cups 31 adsorb the materials at the same time. Taking the activation of the right set of suction cups 31 as an example, the operation steps are: the vacuum pump 4 works, the air outlet 513 of the three-way solenoid valve 51 is closed, the exhaust port 512 and the air inlet 511 of the three-way solenoid valve 51 are opened, the exhaust port 512 and the air inlet 511 are connected, and the air between the suction cup 31 and the materials passes through the flow in turn. The fluid flows through the body channel a61, the air inlet 511 of the three-way solenoid valve 51, the exhaust port 512 of the three-way solenoid valve 51, and the fluid channel c63, and enters the vacuum pump suction hole 41, and then is exhausted by the vacuum pump exhaust hole 42, completing the material adsorption operation of a set of suction cups. At this time, one side of the adsorbed material is slightly lifted, and after breaking the vacuum between it and the next layer of material, the material is slightly moved to place the material, and then the entire material is adsorbed. At this time, the three-way solenoid valve 1 51 and the three-way solenoid valve 2 52 are started at the same time, and the two sets of suction cups are adsorbed on the surface of the material at the same time to perform material adsorption and transportation operations.

[0044] Compared with traditional adsorption devices, the utility model adopts a quick and convenient adapter plate and a combination design of an air duct and a three-way solenoid valve that matches it, which effectively solves the needs of multi-scenario use in automated production, improves the adsorption and handling efficiency and production efficiency for enterprises, saves manpower resources, has market prospects, and is suitable for promotion and application.

[0045] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
