Specific embodiment

Illustrate that the utility model, the following example are merely to illustrate the skill of the utility model below in conjunction with specific embodiment Art scheme, does not limit the protection scope of the utility model.

The two-position three way magnetic valve 1(two-position three way miniature electromagnetic valve 1 used in each embodiment) be have in the market it is general Part comprising suction nozzle port 11, positive air pressure port 12, negative pressure port 13, expansion interface 14.

It can be used for connecing the component of tracheae 8 and other needs that one communicates with suction nozzle port 11 at expansion interface 14 again, When not needing to use, it can be blocked with plug wire.In chip mounter field, herein for placing baroceptor 3, baroceptor 3 use sealing gluing at this.

Working principle:

When power-off, suction nozzle port 11, expansion interface 14 and negative pressure port 13 are obstructed, suction nozzle port 11, expansion It opens up interface 14 and positive air pressure port 12 is logical.

When energization, suction nozzle port 11, expansion interface 14 and negative pressure port 13 are logical, suction nozzle port 11, extension Interface 14 and positive air pressure port 12 are obstructed.

No matter power-off is also switched on, suction nozzle port 11 and expansion interface 14 are all logical.

Embodiment one:

As shown in figs. 1-7, a kind of air valve module, including two-position three way magnetic valve 1, the solenoid valve 1 include suction nozzle port 11, Positive air pressure port 12 and negative pressure port 13 further include further mounting base 2, and the mounting base 2 is raw using the method for mold injection It produces, has the solenoid valve mounting hole 21 of mutual connection thereon, positive pressure gas source connects gas head 22 and splice mouth 23, and form T-type Connection pipeline；Positive air pressure port 12 is docked with solenoid valve mounting hole 21, and positive pressure gas source connects gas head 22 and is connected with positive pressure gas source；Electricity Magnet valve 1 and mounting base 2 form air valve module.

The present embodiment further includes baroceptor 3, and solenoid valve 1 is additionally provided with expansion interface 14(i.e. screw extending bore), and with Suction nozzle port 11, negative pressure port 13 are connected；Baroceptor 3 is installed on expansion interface 14, specifically, baroceptor 3 can use sealant, stick in the expansion interface 14 of two-position three way magnetic valve 1.

The present embodiment further includes sealing ring 4 and docking screw 5, and positive air pressure port 12 is set with 21 place of docking of solenoid valve mounting hole There is sealing ring 4, sealing ring 4 is O-shaped, and is set in outside positive air pressure port 12, it is rear to be fixedly connected by docking screw 5, it is used for two The fixation of position-3-way solenoid valve 1 and mounting base 2, docking screw 5 has four, and is uniformly distributed in by sealing ring 4.

If only used all the way, just with plug wire the splicing mouth 23(threaded hole in mounting base 2) it blocks, if wanting multistage Interconnection then needs rationally benefit splicing mouth 23(such as embodiment two, three).

The present embodiment further includes equipment mounting platform 6 and fixed screw 7, and mounting base 2 is installed on equipment mounting platform 6, Mounting base 2 is fixed on equipment mounting platform 6 by fixed screw 7.

Working principle:

Since solenoid valve mounting hole 21, the positive pressure gas source in mounting base 2 connect gas head 22, splicing mouth 23 communicates.When two Position three-way miniature solenoid valve 1 is fixed in mounting base 2, and with after the sealing of sealing ring 4, two-position three way miniature electromagnetic valve 1 is just Air pressure port 12 is just and the positive pressure gas source in mounting base 2 connects the mutual connection of gas head 22.

The suction nozzle port 11 of two-position three way miniature electromagnetic valve 1 connects using port, in chip mounter field, refers to that chip mounter is inhaled Mouth, negative pressure port 13 connect negative pressure gas source, and the positive pressure gas source in mounting base 2 connects gas head 22 and connects positive pressure gas source.

According to the working principle of aforementioned two-position three way miniature electromagnetic valve 1, it is known that the working principle of the air valve module, In the case where energization, 1 suction nozzle port 11 of two-position three way miniature electromagnetic valve and baroceptor 3 only with two-position three way miniature electromagnetic valve 1 negative pressure port 13 communicates, air valve inside modules be negative pressure state, therefore with 1 suction nozzle port 11 of two-position three way miniature electromagnetic valve What is be connected has negative pressure generation using port, is exactly that suction nozzle has negative pressure in chip mounter field, can be used to draw component, when having When component sucks up, suction nozzle is blocked by component, and air valve inside modules negative pressure value increases, and baroceptor 3 is also at Negative pressure state, with the increase of negative pressure value, the signal value that baroceptor 3 provides will also become larger, for judge suction nozzle either with or without It is drawn to component, or device of changing the title of a reign is askew either with or without inhaling, and to judge, the instruction of further work is carried out to chip mounter.

In cold situation, 1 suction nozzle port 11 of two-position three way miniature electromagnetic valve and baroceptor 3 only with mounting base Positive air pressure port 12 on 2 communicates, and air valve inside modules are barotropic state.

Embodiment two:

Based on embodiment one, if the air valve module of the present embodiment has each, connect between each air valve module by positive pressure gas source Gas head 22 and the splicing mouth 23 of another air valve module are end to end, it can be achieved that multistage interconnection, each air valve module successively structure side by side At component, wherein positive pressure gas source connects gas head 22 and threaded connection directly can be used in splicing mouth 23.

Due to an air valve module, only corresponding suction nozzle all the way has multichannel suction nozzle, that is just needed often on a chip mounter Multiple air valve modules, as seen in figs. 8-10 such as air valve block combiner, with 10 sets of the O-ring seals positive pressure gas sources in mounting base 2 22 outside of gas head is connect, positive pressure gas source is then connect the splicing mouth 23(threaded hole that gas head 22 is inserted into upper level mounting base 2) it is inner, then It with fixed screw 7, is allowed to need a few road gas to connection with equipment mounting platform 6, just nested several air valve modules, at last The splicing mouth 23(threaded hole of a air valve module) on, it is blocked with plug wire.

The effect of positive air pressure only unloads negative pressure, so positive air pressure is just enough to support multiple air valve moulds all the way faster Block.

Embodiment three:

Based on embodiment two, the present embodiment further includes tracheae 8 and pagoda connector 9, the positive pressure gas source between each air valve module It connects between gas head 22 and splicing mouth 23 through 9 trachea of pagoda connector, 8 connection.

For different chip mounters, embodiment two takes up space too greatly, and mode as shown in figure 11 arranges.Mounting base Splicing mouth 23(threaded hole on 2) at, a pagoda connector 9 is twisted, connection tracheae 8 one connects pagoda connector 9, and other end connects installation The positive pressure gas source of seat 2 connects gas head 22, needs a few road gas, just nested several ventilation modules, in the screw thread of the last one ventilation module Kong Shang is blocked with plug wire.

In addition, it should be noted that, the specific embodiments described in this specification, the shape of parts and components are named Title etc. can be different.All equivalent or simple changes done according to structure, feature and principle described in the concept of the patent of the utility model, It is included in the protection scope of the utility model patent.Those skilled in the art of the present invention can be to being retouched The specific embodiment stated does various modifications or additions or is substituted in a similar manner, without departing from the utility model Structure or beyond the scope defined by this claim, all should belong to the protection range of the utility model.
