Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.

The negative pressure adsorption assembly shown in fig. 1 comprises a negative pressure generating head 1 and an adsorption head 2. Wherein, the negative pressure generating head 1 generates negative pressure by using compressed gas, and the adsorption head 2 is connected with the negative pressure generating head 1 and adsorbs the membrane 3 by using negative pressure. As shown in fig. 6, the adsorption head 2 is provided with an adsorption groove 23, the membrane 3 is sucked into the adsorption groove 23, and a plurality of membranes 3 can be simultaneously adsorbed in the adsorption groove 23, and the membranes 3 are embedded in the adsorption groove 23 in a laminated manner.

As shown in fig. 1, the negative pressure generating head 1 has a negative pressure end 11 and an exhaust end 12 at both ends, respectively. The lower end is a negative pressure end 11, and the upper end is an exhaust end 12. Referring to fig. 3, the negative pressure generating head 1 is ring-like and has an air passage 13 extending between the negative pressure end 11 and the exhaust end 12. As shown in fig. 1 and 2, the negative pressure generating head 1 is provided therein with a high pressure air passage 15, the high pressure air passage 15 is for introducing compressed gas, and the high pressure air passage 15 is located in the wall of the upper half of the negative pressure generating head 1, where the wall is thicker to accommodate the high pressure air passage 15. The tail end of the high-pressure air passage 15 is connected with an air outlet hole 14 on the inner wall of the air passage 13. The high-pressure gas in the high-pressure gas passage 15 is released into the gas passage 13 through the gas outlet hole 14. The air outlet hole 14 is annular and extends into a circle on the inner wall of the air passage 13.

As shown in fig. 2, the cross-sectional shape of the air outlet 14 is a flared shape and is biased toward the air outlet end 12, and the air flow released from the air outlet 14 flows toward the air outlet end 12, so that a high-speed air flow is generated in the air duct 13. Due to the primary effort principle, negative pressure is formed in the air duct 13, and the air pressure in the space above the air outlet hole 14 is smaller than the air pressure in the space below the air outlet hole 14. The air flow at the negative pressure end 11 at the lower end is normal atmospheric pressure, so that the air flow is sucked into the space at the upper half part of the air passage 13, and the air in the adsorption head 2 connected with the negative pressure end 11 also flows to the air passage 13.

As shown in fig. 2, the top wall of the gas outlet hole 14 (indicated by B in fig. 2), that is, the top wall near the upper end gas outlet end 12 extends obliquely toward the gas outlet end 12, and is an arc-shaped extension with gradually increasing slope. The bottom wall of the air outlet hole 14 (indicated by C in fig. 2), i.e., the bottom wall distant from the upper end air discharge end 12, is a plane extending horizontally, i.e., a plane perpendicular to the axial direction of the air duct 13. Such a structure causes the air flow discharged from the air outlet hole 14 to flow toward the upper exhaust end 12.

In other embodiments, the shape or orientation of the outlet aperture 14 may be other forms such that the air flow exiting the outlet aperture 14 flows upward. For example, the air outlet 14 may be an air channel extending obliquely upward (i.e., the top wall and the bottom wall of the air outlet 14 are both extending obliquely upward).

The air flow released from the air outlet hole 14 flows upwards to avoid the air flow flowing downwards into the adsorption head 2, thereby influencing the air flow in the adsorption head 2 to flow to the negative pressure generating head 1. And the upper exhaust end 12 may be connected to the atmosphere to receive the exhaust gas flow. In fact, if the air flow in the air duct 13 is in other directions, such as horizontal flow, a negative pressure can be generated in the air duct 13 to suck the air in the adsorption head 2.

In this example, the air outlet holes 14 extend in one turn on the inner wall of the air duct 13, and in other embodiments, two or more turns of the air duct 13 may be provided, and the two or more turns of the air duct 13 may be distributed in the air duct 13 along the axial direction. In this example, the air outlet holes 14 extend one turn, and in other embodiments, the air outlet holes may be multiple points open to the air duct 13.

As shown in fig. 1, the suction head 2 includes a block 21 extended in a plate shape, and as shown in fig. 6, the block 21 is extended in a plate shape to match the shape of the diaphragm 3, thereby facilitating suction of the diaphragm 3.

As shown in fig. 1, the upper surface of the block 21 is provided with a negative pressure connection port 22, and the negative pressure connection port 22 is connected with the negative pressure end 11 and is communicated with the air duct 13, so that air flow can flow to the negative pressure center, namely the space of the upper half part of the air duct 13. The lower surface of the block 21 is provided with an adsorption groove 23 communicated with the negative pressure connection port 22. The membrane 3 is sucked into the adsorption tank 23 by negative pressure.

As shown in fig. 4 and 5, the adsorption groove 23 extends from the lower surface of the block 21 (i.e., the lower surface in fig. 1) into the block 21. At least a portion of the bottom surface 231 of the adsorption groove 23 extends inward to form a negative pressure passage 24. First supporting strips 25 are arranged in parallel between the negative pressure channels 24, namely, the space between the first supporting strips 25 is the negative pressure channel 24. The negative pressure passage 24 communicates with the negative pressure connection port 22. The first supporting bars 25 are juxtaposed and extend in parallel to the bottom surface of the adsorption tank 23. The bottom surface 231 of the adsorption groove 23 is further provided with a communication groove 27, and the communication groove 27 transversely penetrates all the first support bars 25, thereby communicating spaces between adjacent first support bars 25, so that all gaps between the first support bars 25 serve as a part of the negative pressure passage 24. The first support bar 25 is used for supporting the membrane 3.

As shown in fig. 5, two first support bars 25 adjacent to the edge of the negative pressure connection port 22 are provided with transverse notches 28, and the positions of the notches 28 are set corresponding to the negative pressure connection port 22, so that the air flow in the negative pressure channel 24 flows to the negative pressure connection port 22 more quickly.

As shown in fig. 4 and 5, the suction passage 24 extends along the bottom surface 231 of the suction groove 23 up to the side wall 211 of the block 21, and extends into the side wall 211. And extends in an outward direction within the sidewall 211 and up to the outer end of the sidewall 211. And a circle of side walls 211 are distributed with negative pressure channels 24. And the negative pressure passages 24 in the side wall 211 are juxtaposed. A second support bar 26 is formed between adjacent negative pressure channels 24, the second support bar 26 serving to support the periphery of the membrane 3.

In this example, the second support bar 26 extends from the inner side to the outer side at the side wall 211, but may extend horizontally or in other directions.

In this example, the negative pressure channel 24 in the sidewall 211 extends all the way to the outer end of the sidewall 211, but in other embodiments, it may not extend to the outer end.

The negative pressure passage 24 in the side wall 211 allows a peripheral side wall 211 to form an air flow due to the negative pressure in the negative pressure generating head 1, and the entire thickness of the side wall 211 can form an air flow. When the membrane 3 is adsorbed in the adsorption tank 23, the membrane 3 can be adsorbed again by the airflow of the side wall 211. The principle of which is shown in figure 6.

As shown in fig. 6, when the membrane 3 is sucked into the suction groove 23, the next membrane 3 can be sucked by the negative pressure passage 24 in the side wall 211.

The negative pressure passage 24 in the side wall 211 is long enough so that after the membrane 3 is sucked in the suction groove 23, the negative pressure passage 24 has an exposed portion so that an air flow is generated in the remaining space of the suction groove 23 to suck the next membrane 3. In the case where the negative pressure passage 24 in the side wall 211 is shortest, the suction groove 23 can be made to have an exposed portion enough to suck the next membrane 3 in the case where one membrane 3 is sucked.

In this example, the negative pressure passage 24 in the side wall 211 is entirely open to the adsorption tank 23. In other embodiments, the negative pressure channel 24 in the sidewall 211 may also be in communication with the adsorption tank 23 through a plurality of openings. The plurality of openings are distributed on the side wall 211 in the depth direction of the adsorption groove 23.

As shown in fig. 6, the suction grooves 23 are provided with negative pressure channels 24 at the corners, namely, the corners of the side walls 211, namely, the positions indicated by D in fig. 6, so that negative pressure is formed at the corners of the suction grooves 23, thereby facilitating the attachment of the four corners of the diaphragm 3 in the suction grooves 23 and preventing the deformation of the diaphragm 3.

The adsorption head 2 of this example can adsorb multi-disc diaphragm 3 simultaneously to once carry multi-disc diaphragm 3, improved transport efficiency. In the prior art, for example, the adsorption heads can only adsorb one membrane in Chinese patent 'CN 217126233U', 'CN 210253949U', 'CN 112590349A'.

In this example, the negative pressure generating head 1 generates negative pressure by using the Bernoulli principle, and can utilize the existing compressed gas generating system of the production workshop without independently configuring a vacuum system, so that the improvement of the workshop is small, and the device can be rapidly applied.

The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
