[0060] The working process of the adsorption unit 10 in the embodiment of the present application is as follows:

[0061] When it is necessary to implement suction of the sheet located below the adsorption unit 10, the solenoid valve 4 is controlled to connect the air supply path 6 and the first blowing path 7, block the first blowing path 7 and the air release path 8, and control the air supply of the air source, so that the high-pressure gas supplied by the air source enters the first air cavity through the air supply path 6 and the first blowing path 7 in turn, and is finally blown out at high speed to the first side of the base 1 through the first blowing slit 5, thereby generating a suction area in the lower area of ​​the base 1 to implement suction of the sheet.

At the same time, the solenoid valve 4 is controlled to block the air supply path 6 and the first blowing path 7, and connect the first blowing path 7 and the deflation path 8, so that the residual high-pressure gas in the first blowing path 7 is quickly discharged through the deflation port of the deflation path 8, thereby making the adsorption area in the lower area of ​​the base 1 disappear quickly.

[0063] Compared with the existing adsorption unit, the main air circuit of the adsorption unit in the embodiment of the present application is arranged in the base, and only an external pipeline is needed to connect the air supply circuit and the external air source, which is easy to install and simplifies the layout of the sheet picking component, while also reducing the interference with the sheet picking component.

That is, the high-pressure gas provided by the external air source enters into each air path in the base 1 via the unified air inlet connector 9, thereby further simplifying the structure of the sheet taking assembly.

Figure 3 In the illustrated embodiment, four first grooves 33 are provided on the first side edge of the gasket 31 , and correspondingly, four first air cavities are formed in the core body 3 .

[0068] By configuring the core body 3 to include a gasket 31 and a core plate 32 and providing a first groove at the edge of the gasket 31 , a first air cavity can be formed after the gasket 31 and the core plate 32 are installed in the installation groove 2 in the base 1 .

[0070] In order to facilitate the processing of the mounting groove 2 and the core plate 32, the mounting groove 2 is optionally a V-shaped groove, and the mounting groove 2 has a first inclined surface inclined downward toward the first side of the base 1, and a second inclined surface inclined downward toward the second side of the base 1. Correspondingly, the core plate 32 has a third inclined surface matching the first inclined surface, and a fourth inclined surface matching the second inclined surface, wherein the third inclined surface and the first inclined surface block a plurality of first grooves 34 from both upper and lower sides to form a plurality of first air cavities.

[0071] In order to achieve the communication between the first air cavity and the first blowing air path 7, the high-pressure air in the first blowing air path 7 can flow into the first air cavity at a high speed. Figure 3 As shown, a plurality of first blowing holes 16 are provided in the base 1, and each first air cavity is connected to the first blowing air path 7 via at least one first blowing hole 16.

In an application scenario, the first blocking member is inserted into the first blocking hole 11b at the middle position, and the first blocking holes 11a and the first blocking holes 11c are both inserted with the first blocking members. At this time, the first blowing air path 7 is blocked at the position corresponding to the first blocking hole 11b, so the high-speed gas can only enter the first blocking hole 11b and one end of the base 1 (such as Figure 1 Finally, a negative pressure area is generated at the corresponding position at the bottom of the base 1 in the first blowing air path 7 between the A end in the middle.

Optionally, the second blocking member is a long screw, which can be inserted into the second air blowing path 13 and the inner end of the screw abuts against the inner wall of the second air blowing path 13, thereby blocking the second air blowing path 13. The second blocking member is a short screw, which only blocks the second blocking hole 15 to prevent gas from leaking from the second blocking hole 15, and the inner end of the short screw does not abut against the inner wall of the second air blowing path 13.
