the valve core 432 is slidably arranged in the valve cavity 4311, one end of the valve core 432 can extend into the second air passage 4313, and the other end of the valve core 432 penetrates out of the adsorption body 431; the plugging driving component 433 is used for driving one end of the valve core 432 to plug the second air channel 4313 under the action of air flow in the second air channel 4313; an elastic push rod 436 is fixed on the adsorption body 431 and is used for wedge-shaped matching with the other end of the valve core 432; the elastic locking component 434 is hinged in the locking cavity 4315, one end of the elastic locking component 434 is movably hinged with the valve core 432, and the other end of the elastic locking component 434 is abutted against the inner bottom wall of the locking cavity 4315; the vacuum chuck 435 is connected to one end of the first air passage 4312;
as shown in fig. 2 to 5, the gripping mechanism 4 further includes a reset driving assembly 44, and the reset driving assembly 44 is disposed on the gripping bracket 41 and is used for cooperating with the elastic push rod 436 so as to reset the valve core 432 in the state of blocking the second air passage 4313. In the embodiment, the conveying mechanism 1 adopts a conveying belt structure, so that the conveying of the porous aluminum single plate is facilitated, and the grabbing mechanism 4 is also facilitated to adsorb and grab the porous aluminum single plate; the exhaust 4314 is connected to an external vacuum generator.
When the multi-hole aluminum veneer processing device works, the conveying mechanism 1 conveys the multi-hole aluminum veneer to be processed to a position to be grabbed, the joint mechanical arm 3 drives the grabbing mechanism 4 to move to the position above the multi-hole aluminum veneer to be grabbed, and then the joint mechanical arm 3 drives the grabbing mechanism 4 to downwards explore, so that the vacuum chuck 435 of the adsorption unit 43 is abutted against the surface of the multi-hole aluminum veneer; after the bonding is completed, the external vacuum generator vacuumizes the space formed between the vacuum chuck 435 and the porous aluminum veneer through the exhaust port 4314, the second air passage 4313 and the first air passage 4312, at this time, because the porous aluminum veneer has the through holes, a part of the vacuum chuck 435 positioned above the through holes of the porous aluminum veneer cannot form a sealed space with the porous aluminum veneer, therefore, continuous high-speed air flow is formed in the second air passage 4313 of the corresponding adsorption unit 43, the high-speed air flow enables the blocking driving component 433 to push the valve core 432 to move in the valve cavity 4311, the valve core 432 extends into the second air passage 4313 to block the second air passage 4313, meanwhile, the valve core 432 drives the elastic locking component 434 to swing, and after the second air passage 4313 is blocked, the continuous high-speed air flow disappears, the elastic locking component 434 simultaneously locks the valve core 432, so that the valve core 432 keeps to block the second air passage 4313, thereby realizing the air passage cutting of the adsorption unit 43 which does not play a role in adsorption, the vacuum degree of the whole vacuum system is prevented from being lowered due to the air leakage of the adsorption unit 43, and the adsorption of the porous aluminum veneer is more reliable to capture;
for the adsorption unit 43 forming a good sealed space with the porous aluminum veneer, because the air volume in the sealed space is limited, continuous high-speed air flow cannot be formed, and therefore the corresponding plugging driving component 433 cannot drive the valve core 432 to slide in the valve cavity 4311, so that the corresponding second air passage 4313 is kept in an open state, the external vacuum generator can continuously vacuumize the sealed space, and the reliability of adsorption grabbing is improved;
for the adsorption unit 43 with poor sealing and slight leakage, the leaked air quantity is smaller, so that the air flow of the second air passage 4313 cannot continuously drive the valve core 432 to slide, namely the second air passage 4313 is kept in an open state, and the external vacuum generator can continuously vacuumize the sealed space, so that the whole grabbing mechanism 4 can keep good adsorption grabbing reliability;
after the adsorption grabbing is completed, the joint mechanical arm 3 drives the grabbing mechanism 4 and the adsorbed and grabbed porous aluminum single plate to move to the workbench 2, then the vacuum chuck 435 is enabled to release the adsorption of the porous aluminum single plate, meanwhile, the reset driving assembly 44 is matched with the elastic push rod 436, the valve core 432 slides, the second air passage 4313 is enabled to be in an open state, meanwhile, the valve core 432 drives the elastic locking assembly 434 to swing reversely, and after the second air passage 4313 is in a complete opening state, the elastic locking assembly 434 locks the valve core 432, so that the valve core 432 is reset, and the transportation and the conveying of the porous aluminum single plate are completed.
