For this paper purpose, technical scheme and advantage are more clearly understood, below in conjunction with reality of the accompanying drawing to this paper Example is applied to be described in detail.It should be noted that in the case where not conflicting, the spy in embodiment and embodiment in the application Levying mutually to be combined.

Many details are elaborated in the following description in order to fully understand herein, still, can also be adopted herein It is different from mode described here to implement with other, therefore, this paper protection domain is not by following public specific implementation The limitation of example.

The pressure head of some embodiments herein is described below in conjunction with the accompanying drawings.

The pressure head that the present invention is provided, as shown in figures 1 and 3, including：Mounting hole 11 is provided with body 1, the body 1 With multiple first stomatas 12, multiple first stomatas 12 are communicated with the mounting hole 11；With tracheae 2, set on the tracheae 2 Multigroup stomata 21 is equipped with, multigroup stomata 21 is in the circumferentially-spaced arrangement of the tracheae 2, and stomata 21 described in any group includes multiple Second stomata 22, and the quantity of multiple second stomatas 22 contained by stomata 21 described in any group is described no more than multiple The quantity of first stomata 12；Wherein, the tracheae 2 is rotationally sealingly mounted in the mounting hole 11, in multigroup stomata Any group can make multiple second stomatas 22 and the first of identical quantity contained by this group of stomata by rotating the tracheae 2 Stomata 12 corresponds connection.

The pressure head that the present invention is provided, position of the tracheae 2 in mounting hole 11 is adjusted by rotating tracheae 2, to select gas Corresponding one group of stomata correspondence is on the first stomata 12 on pipe 2, the quantity of multiple second stomatas 22 contained by one group of stomata Correspond and connect with the first stomata 12 of identical quantity, to change the usage quantity of the first stomata 12 so that used the Length range shared by one stomata 12 changes, the size to be adapted to corresponding chip on film, equivalent to having changed different pressures Head, and the first stomata 12 not connected also be not present gas leakage the problem of, the step of eliminating replaceable pressure head and adjusting device, no Equipment adjustment time can only be reduced, production efficiency is improved, moreover it is possible to the acquisition cost of pressure head is reduced.

Alternatively, as shown in Figure 1 to Figure 3, the pressure head also includes：Actuator, installed in the end of the tracheae 2, is used In driving the tracheae 2 to be rotated in the mounting hole 11, more convenient for rotating tracheae 2 in mounting hole 11, and cut with this Any group changed in multigroup stomata and the corresponding connection of the first stomata 12, the different rotation angle of knob 3, corresponding on selection tracheae 2 One group of stomata of the different quantity of second stomata 22.

Further, as shown in Fig. 2 the pressure head also includes：Gear mark 13, is arranged on the body 1 and closes on In being provided with sign 31 on the actuator, the actuator, and gear mark 13 is included in the actuator Multiple (as shown in Fig. 2 with 8 gears mark) of circumferentially-spaced setting, the quantity of multiple gears marks 13 with it is many The quantity of the group stomata 21 is identical, and multiple gear marks 13 are corresponded in multigroup stomata 21 respectively with the One stomata 12 at the signified multiple positions of the sign 31, more conducively debugs tracheae 2 so that one group of gas of selection when connecting Hole is connected with the rapid-aligning of the first stomata 12.

Specifically, as shown in Fig. 2 the actuator is knob 3, the sign 31 is the convex tendon or recessed on knob 3 Groove, gear mark 13 can be made using technologies such as printing, etchings.

Furthermore, the external diameter of the tracheae 2 is identical with the aperture of the mounting hole 11, and the tracheae 2 and the mounting hole Sealing ring is additionally provided between 11 hole wall, to prevent vacuum leak.

Moreover, as shown in figure 3, multigroup stomata 21 each contained multiple second stomatas 22 quantity not Identical, the stomata of each different groups of correspondence of gear mark 13, the quantity of the second stomata 22 contained by any group of stomata is determined The size of chip on film can be drawn, absorption of the same pressure head to sizes chip on film is realized and supplies.

Specifically, as shown in figures 1 and 3, second stomata 22 contained by stomata 21 described in any group is from the gas The middle part of the tube wall of pipe 2 is outwards set gradually, and multiple first stomatas 12 are uniformly arranged and on same straight line, multigroup The stomata 21 is on a plurality of bus of the tracheae 2, multiple second stomatas contained by stomata 21 described in any group 22 are uniformly arranged, and the spacing of adjacent first stomata 12 and second stomata 22 adjacent in stomata 21 described in any group Spacing all same, can so reduce the design difficulty and manufacture difficulty of pressure head.

Wherein, as shown in figure 1, the mounting hole 11 is opened on the side of the body 1 and is through hole, Duo Gesuo The first stomata 12 is stated to be opened on the bottom surface of the body 1 and upper end and the insertion of mounting hole 11.

In summary, the pressure head that the present invention is provided, position of the tracheae in mounting hole is adjusted by rotating tracheae, to select Corresponding one group of stomata correspondence is selected on tracheae on the first stomata, the quantity of multiple second stomatas contained by one group of stomata with First stomata of identical quantity corresponds connection, to change the usage quantity of the first stomata so that used first stomata Shared length range changes, the size to be adapted to corresponding chip on film, equivalent to having changed different pressure heads, Er Qiewei The problem of also gas leakage is not present in first stomata of connection, the step of eliminating replaceable pressure head and adjusting device can not only be reduced Equipment adjustment time, raising production efficiency, moreover it is possible to reduce the acquisition cost of pressure head.
