In the embodiment of the present invention, the independent negative pressure chamber unit 1 includes a negative pressure chamber box body 3 and a negative pressure chamber panel 4 installed on the negative pressure chamber box body 3. A number of negative pressure siphon holes 5 are evenly distributed on the negative pressure chamber panel 4 of each independent negative pressure chamber unit 1. In the embodiment of the present invention, the negative pressure siphon holes 5 are evenly distributed, which is beneficial to the uniform distribution of the negative pressure extraction pressure. The negative pressure siphon holes 5 are external funnel-shaped structure siphon holes, which is beneficial to the inhalation of external air to form a rotational wind pressure in the form of a tornado, and at the same time form a small vortex suction port respectively, which can improve the adsorption force.

[0042] The negative pressure chamber panel 4 is installed on the negative pressure chamber box body 3 to form an independent hollow box structure. Each independent negative pressure chamber unit 1 can be regarded as a small vacuum adsorption platform, forming a negative pressure unit body to meet the uniform entry of external air into the negative pressure siphon holes. A number of independent negative pressure chamber units 1 are combined to form the vacuum adsorption platform body 2, and are combined and used to meet the large-area adsorption requirements.

[0043] This combined vacuum adsorption platform is combined and used by multiple independent negative pressure chamber units 1, and the size can be assembled arbitrarily according to different usage requirements of customers. And each independent negative pressure chamber unit 1 can independently control its negative pressure requirements, so as to facilitate customers to turn on or off different areas according to different usage conditions to meet the complex usage requirements of zoning control.

[0045] An independent negative pressure bin channel 9 is provided inside the negative pressure bin box body 3. A channel controller 10 is connected to the independent negative pressure bin channel 9, and a controller pipeline 11 is connected to the channel controller 10. In the embodiment of the present invention, a number of controller fixing holes 17 are provided inside the negative pressure bin box body 3 for fixing the channel controller 10 on the inner wall of the negative pressure bin box body 3. A negative pressure bin panel support column 21 is also fixed on the inner wall of the negative pressure bin box body 3. A support column positioning pin 24 is provided on the inner wall of the negative pressure bin panel 4, and the position of the support column positioning pin 24 corresponds to the position of the negative pressure bin panel support column 21 one by one, which is convenient for connecting the negative pressure bin box body 3 and the negative pressure bin panel 4, and ensures that after connection, the negative pressure bin box body 3 also has a good supporting effect on the negative pressure bin panel 4. A number of negative pressure channel pressing beams 23 are provided on the inner wall of the negative pressure bin panel 4. The negative pressure channel pressing beams 23 are parallel and equally spaced, which is beneficial to tightly pressing and fixing the independent negative pressure bin channel 9 between the negative pressure bin panel 4 and the negative pressure bin box body 3, and also improves the structural strength of the negative pressure bin panel 4.

A cylinder is installed at the negative pressure inlet of the controller pipeline 11, and a rubber soft pad is installed at the top of the piston rod of the cylinder. When this area of the independent negative pressure bin unit 1 is not in use, the external control switch is turned on to control the action of the cylinder. The piston rod of the cylinder drives the rubber soft pad to act on the negative pressure inlet to meet the usage requirements of switching this area.

[0047] In the embodiment of the present invention, a negative pressure ventilation hole is reserved on the side of the negative pressure bin box body 3 of each independent negative pressure bin unit 1, and a sealing ring is provided to meet the sealing requirements of splicing; the combined body positioning pin 7 is for allowing each independent independent negative pressure bin unit 1 to be closely fitted and connected to form the vacuum adsorption platform body 2 during splicing.

[0048] Furthermore, the negative pressure ventilation hole includes a controller fixing hole 17 and a channel fixing hole, which are respectively used for the controller pipelines 11 of adjacent independent negative pressure bin units 1 to communicate and the independent negative pressure bin channels 9 to communicate. Among them, a combined body controller hole sealing ring 12 is provided in the combined body controller hole sealing ring groove 14, and a combined body channel hole sealing ring 13 is provided in the combined body channel hole sealing ring groove 20 to increase the sealing performance of the connection between the controller pipeline 11 or the independent negative pressure bin channel 9.

[0050] A sealing glue filling groove 15 is provided at the connection between the negative pressure bin box body 3 and the negative pressure bin panel 4, and a sealing positioning group stop 16 is also provided on the negative pressure bin box body 3. When the negative pressure bin panel 4 is limited by the sealing positioning group stop 16, it is convenient to be butted against the negative pressure bin box body 3. At the same time, it is also convenient to fill glue in the sealing glue filling groove 15 to increase the sealing performance of the connection between the two.

[0051] A negative pressure channel buckle 22 is also provided on the negative pressure bin box body 3. Glue needs to be applied at the negative pressure channel buckle to fix the independent negative pressure bin channel 9. Due to the requirement of overall sealing performance, no holes can be drilled. Therefore, the independent negative pressure bin channel 9 can only be fixed by glue, and then the independent negative pressure bin channel 9 is pressed by the negative pressure channel pressing beam 23 to keep the independent negative pressure bin channel 9 in its position unchanged.
