The invention provides a sucker device which comprises an air suction cover 2, wherein the top of the air suction cover 2 is connected with a fan through an air suction pipe 1 and used for sucking air in the air suction cover 2, the outer side surface of a bottom plate 21 of the air suction cover is an air suction surface, a plurality of air suction ports 22 are formed in the air suction surface of the air suction cover 2, a plurality of sealing rings 4 which correspondingly surround the air suction ports 22 one by one are arranged on the outer side of the air suction cover 2, at least one air suction port 22 is provided with a self-locking valve 6, the self-locking valve 6 comprises a valve shell 61 and a valve core, the valve shell 61 is provided with a valve channel communicated with the air suction ports 22 in a penetrating manner, the valve core is movably connected to the valve shell 61 through a reset mechanism, the reset mechanism is used for driving the valve core to be communicated with the valve channel and the air suction ports 22, and the valve core can partially block the valve channel and/or the air suction ports 22 along the air suction direction under the air suction effect. Wherein, the valve core leads the valve channel and the air suction opening 22, the valve core is in a lead-through position and leads the valve channel to be communicated with the air suction opening 22; the valve core part is used for blocking the valve channel and/or the air suction opening 22, namely the valve core blocks part of through-flow cross sections of the valve channel and/or the air suction opening 22, namely when the valve core is at a part of blocking positions, certain through-flow gaps for air circulation are reserved between the valve core and the valve channel and/or between the valve core and the air suction opening 22, when the fan operates, air on the outer side of the air suction hood 2 can flow into the interior of the air suction hood 2 through the through-flow gaps, meanwhile, the fan continuously pumps the air in the air suction hood 2, so that negative pressure is formed in the air suction hood 2, pressure difference is generated on the inner side and the outer side of the valve core immediately, and the valve core can overcome the acting force of the reset mechanism under the air suction effect (namely under the action of the inner pressure difference and the outer pressure) and keep at a part of blocking positions.
It should be noted that the initial position of the valve element is designed to partially block the valve channel and/or the air suction opening 22, rather than completely block the valve channel and/or the air suction opening 22, because if the valve element blocks the flow cross section of the valve channel and/or the air suction opening 22, the contact portion of the valve element and the valve channel and/or the air suction opening 22 cannot form an air flow, and when the air suction hood 2 presses the plate 3, the air in the adsorption area 5 enclosed by the air suction hood 2 and the plate 3 cannot be sucked by the fan of the air suction hood 2, so that a negative pressure cannot be formed in the adsorption area 5, and the plate 3 cannot be effectively adsorbed. According to the scheme, the valve channel and/or the air suction opening 22 are/is partially blocked, effective adsorption can be smoothly realized, meanwhile, when the air suction cover 2 does not adsorb plates, all the valve cores are in partial blocking positions, the flow cross section of the direct communication between the air suction opening 22 and the external atmosphere is greatly reduced, and compared with a structure that the air suction opening is directly communicated with the external atmosphere in the prior art, the air pressure control device can provide enough air pressure by configuring a fan with smaller power, so that the weight and the power consumption of the whole machine are effectively reduced.
It should be noted that, in this scheme, the opening degree of the corresponding self-locking valve 6 when the valve element is in the on position is greater than or equal to a first preset opening value, and the opening degree of the corresponding self-locking valve 6 when the valve element is in the partial plugging position is greater than 0 and less than or equal to a second preset opening value, where the second preset opening value is less than the first preset opening value. For example, the first preset opening value is 90%, the second preset opening value is 10%, and the opening degree of the valve element in a partial plugging position is obviously smaller than that of the valve element in a conduction position. Specifically, the valve element can be located at a partial blocking position through various structural designs, for example, a contact surface between the valve element and the valve channel and/or the air suction opening 22 is designed to be an uneven contact surface, a through-flow gap is formed by utilizing a gap between the contact surfaces, the size of the through-flow gap can be designed to be less than 5% or less than 1% corresponding to the opening degree of the self-locking valve 6, so that the negative pressure level in the air suction hood 2 is further maintained, and correspondingly, when the valve element is far away from the matching surface of the valve channel and/or the air suction opening 22, the valve element moves towards the direction of the conducting position; the invention can also design the matching relation of the valve core and the valve channel and/or the air suction opening 22 as the matching relation of a cone body and a cone hole which can move along the axial direction, the opening value of the self-locking valve 6 is changed by changing the position of the conical valve core in the cone hole, and when the conical valve core is at a part of plugging position, the through-flow clearance is ensured to be left between the surface of the conical valve core and the inner surface of the cone hole by designing a limiting bulge. The present invention may also realize the above functions through other structural forms, which are not described in detail herein.
The working principle of the invention is as follows:
when the sucking disc device during operation, the fan starts the operation and forms the negative pressure in the cover 2 inboard that induced drafts, and at this moment, the case is the partial shutoff of effect of induced drafting and is blocked valve passageway and/or inlet scoop 22, begins the absorption operation when the cover 2 outside pressure of induced drafts is on 3 surfaces of panel. For the air suction opening 22 provided with the self-locking valve 6, if the surface of the plate 3, which is surrounded by the sealing ring 4 correspondingly, is not damaged, an adsorption area 5 is formed among the surface of the plate 3, the sealing ring 4 and the self-locking valve 6, and the contact part of the sealing ring 4 and the surface of the plate 3 can form effective contact sealing, so that the communication between the adsorption area 5 and the outside atmosphere is blocked. Because the fan continuously operates and a certain gap is left between the valve core and the valve channel and/or the air suction opening 22, under the action of negative pressure suction force inside the air suction cover 2, air in the adsorption area 5 is sucked to the inside of the air suction cover 2 through the gap and then is discharged by the fan, so that the pressure of the adsorption area 5 is quickly reduced, meanwhile, along with the reduction of the air in the adsorption area 5, the air suction effect on the valve core is quickly weakened, the valve core is continuously driven by the reset mechanism to move, when the pressure of the adsorption area 5 is consistent with that of the inside of the air suction cover 2, the pressure of the inner side and the outer side of the valve core is consistent, air suction airflow cannot be formed, the air suction effect on the valve core is also disappeared immediately, the reset mechanism drives the valve core to reach the position of conducting the valve channel and the air suction opening 22, at the moment, the adsorption area 5 is communicated with the inside of the air suction cover 2 to form a same cavity, the suction opening 22 surrounded by the sealing ring 4 can exert effective adsorption force on the plate 3 under the action of negative pressure.
If there is the damage on the surface that sealing washer 4 corresponds panel 3 that surrounds, then, because outside atmosphere can be through the damaged department to the adsorption zone 5 that sealing washer 4 surrounds constantly supply the air, consequently, the pressure in the adsorption zone 5 can't reduce to the level unanimous with the cover 2 inboard that induced drafts, there will be pressure differential always inside and outside both sides of case, thereby make the induced draft effect that the case received can not weaken, the case will keep in the position of part shutoff valve passageway and/or inlet scoop 22 under the effect of continuous induced draft, and then maintain certain negative pressure in the cover 2 that induced drafts.
In conclusion, the self-locking valve 6 is additionally arranged at the air suction opening 22, so that when the plate 3 is damaged, the self-locking valve 6 is automatically closed, and sufficient air pressure is ensured; when the plate 3 is not damaged, the self-locking valve 6 is automatically opened, and the plate suction operation is carried out by utilizing negative pressure.
It should be noted that, when the number of damaged plates 3 or the damaged area on the surface of the plate 3 is less than the set value, the plate 3 is considered to be a qualified plate, and the air suction hood 2 can apply enough suction force to the whole plate 3 through enough air suction openings 22, so that the plate 3 can be sucked by overcoming the gravity of a single plate 3. When the number of the damaged parts or the damaged area on the surface of the plate 3 exceeds the allowable set value, it indicates that the damaged parts on the plate 3 are too large or too large, the plate 3 can be considered as an unqualified plate, and the number of the air suction openings 22 through which the air suction hood 2 can apply effective adsorption force to the plate 3 is correspondingly small, so that the air suction hood 2 cannot overcome the gravity of a single plate 3 to adsorb the plate 3, and therefore, the quality of the plate can be inspected in the implementation process of the scheme. Preferably, this scheme can add detection panel device and alarm device on above-mentioned suction disc device's basis, when unqualified panel not adsorbed by the cover 2 that induced drafts, it does not have panel 3 to detect the cover 2 below of induced drafts through modes such as position detection or weight detection, shows that this absorption operation in panel 3 is unqualified panel, it can send detected signal to alarm device and carry out sound or light warning suggestion to detect the panel device, thereby be convenient for operating personnel or select the board device in time to remove unqualified panel, the quality of follow-up panel processing has been guaranteed.
It should be noted that, this scheme can realize only adsorbing and promoting a qualified panel in the absorption operation at every turn through carrying out specific matching design to fan power and the area of induced draft cover 2, and specific examples are as follows: assuming that the maximum gravity of the qualified plate is G, the maximum allowable damaged area of the qualified plate is S1, the total area of the suction surface of the suction hood 2 is S, and the maximum wind pressure that the fan can provide through the suction hood 2 is P, then P is G/(S-S1), and then the power W of the fan can be calculated according to the relationship between the wind pressure and the power.
It should be noted that the connection relationship between the valve core and the valve housing 61 can be designed in various forms, such as a connection relationship in which the valve core moves back and forth in the valve housing 61, a connection relationship in which the valve core swings back and forth or rotates back and forth in the valve housing 61, and so on. In a preferred embodiment, the valve core is located inside the valve channel and can reciprocate along the extending direction of the valve channel, a communication hole 69 for plugging and limiting with the valve core is arranged inside the valve channel, the valve core comprises a valve core matching part for plugging and matching with the communication hole 69, and a moving space 60 for reciprocating movement of the valve core matching part is arranged between the air inlet of the valve channel and the communication hole 69. When the valve core matching part moves to a position contacting with the end face of the communication hole 69, the valve core is in a partial blocking position; when the spool engagement portion is away from the communication hole 69, the spool is in the on position.
In a specific embodiment, the valve core includes a valve core rod 62 and a valve core matching portion, the valve core matching portion is disposed around the periphery of the valve core rod 62, the valve core matching portion extends radially outward from the outer surface of the valve core rod 62, a side surface of the valve core matching portion facing the communication hole 69 is a blocking surface, an airflow channel for flowing air is disposed between the periphery of the valve core matching portion and the inner wall of the valve channel, as shown in fig. 2, the self-locking valve 6 is in a conducting position, and the communication hole 69 is communicated with the air inlet of the valve channel and the air outlet 67 of the valve channel by the airflow channel, so that the air flow can smoothly pass through the valve channel. As shown in fig. 3, when the latching valve 6 is in the partially blocking position, the contact surface of the valve element engagement portion and the communication hole 69 is not in sealing contact, but a certain flow gap is left for the air to flow through.
Preferably, the valve core rod 62 axially penetrates through the air inlet of the communication hole 69 and/or the valve channel, and the arrangement is such that the valve core rod 62 can be axially guided by the air inlet of the communication hole 69 and/or the valve channel when the valve core reciprocates in the valve housing 61, so as to avoid the valve core rod 62 from shaking at will, and meanwhile, in order to ensure that the air flow can smoothly flow through the valve channel, a gap 621 for flowing of the air flow is arranged between the valve core rod 62 and the communication hole 69 and/or between the valve core rod 62 and the air inlet of the valve channel.
It should be noted that the valve core rod 62 in the present embodiment may be designed as a cylindrical rod, a prismatic rod, or other rod-shaped structure, in a preferred embodiment, the valve core rod 62 includes a plurality of elongated ribs, the ribs extend along the length direction of the valve core rod 62, and the ribs are radially arranged around the axis of the valve core rod 62, the outer periphery of the valve core rod 62 contacts with the inner ring of the communication hole 69 and/or the inner ring of the air inlet of the valve channel, so as to guide the axial movement of the valve core rod 62, and a notch 621 is formed between every two adjacent ribs, as shown in fig. 4, the cross section of the valve core rod 62 in the present embodiment is in a cross shape.
It should be noted that the valve core matching portion may be designed to have a plate structure, a column structure, a cone structure, or the like. Preferably, the valve core matching portion in this scheme is the valve plate 63, and the inner end surface of the air inlet of the valve passage is a limiting surface 641 that prevents the valve plate 63 from coming out of the valve passage. When the self-locking valve 6 is assembled, the movable range of the valve plate 63 is defined between the communication hole 69 and the stopper surface 641.
Preferably, a limiting structure is arranged between the inner end surface of the air inlet of the valve passage and the valve plate 63, and the limiting structure is used for forming a ventilation gap for air flow circulation between the valve plate 63 and the air inlet.
