Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1 and Figure 2 be a kind of vacuum switching device shifter of chip mounter, it is connected with Pneumatic vacuum device and the vacuum generator of chip mounter, Pneumatic vacuum device comprises multiple working head 6(wherein, a working head is only shown) in figure, each working head 6 comprises an air inlet and a suction nozzle, and air inlet communicates with suction nozzle.
The vacuum switching device shifter of chip mounter of the present utility model comprises vacuum annulus 4, vacuum disk 3 and the motor 5 for driving vacuum disk 3 to rotate; Vacuum annulus 4 is fixedly installed and the upper surface of its lower surface and vacuum disk 3 is fitted, as shown in Figure 3, Figure 4, vacuum annulus 4 comprise be arranged on the first vacuum tank 43 and second vacuum tank 44 of lower surface and be separately positioned on the first vacuum tank 43 and the second vacuum tank 44 in two through holes 41,42, each through hole is connected with a vacuum generator respectively, in the present invention, be provided with two vacuum generators 1,8, be understandable that, the vacuum switching device shifter of chip mounter also comprises two tracheaes 2,7, and each tracheae connects a vacuum generator and a through hole.In addition, the first vacuum tank 43 and the second vacuum tank 44 are deep-slotted chip breaker.
As shown in Figure 5, vacuum disk is evenly provided with the pore identical with working head quantity 31 on 3 bottom surfaces, and the spacing that adjacent pore is 31 is identical, and the quantity of pore 31 is greater than the quantity (being greater than 2) of through hole; Working head 6 is fixedly mounted on vacuum disk 3 belows, and each pore 31 communicates with an air inlet respectively, that is to say the corresponding working head 6 of each pore 31.In the time of actual installation, a pore 31 on vacuum disk 3 communicates with the first vacuum tank 43, and remaining pore 31 communicates with the second vacuum tank 44; Be appreciated that thus the pore 31 communicating with the second vacuum tank 44 has two at least, in other words, the arc length of the second vacuum tank 44 is greater than the arc length of the first vacuum tank 43.Because chip mounter once only has a suction nozzle in suction state in suction process, so be understandable that, the pore 31 communicating with the first vacuum tank 43 is communicated with vacuum generator 8 and a corresponding working head 6, the suction nozzle of this working head 6 is in suction state, and the pore 31 that all the other communicate with the second vacuum tank 44 is communicated with another vacuum generator 1 working head 6 corresponding with it, the also not suction of these working heads 6, also may complete suction process, under the effect of vacuum generator 1, avoid material casting to occur.
In preferred embodiment of the present invention, be provided with 20 pores 31 on vacuum disk, one of them pore 31 communicates with the first vacuum tank 43, and remaining nineteen pore 31 communicates with the second vacuum tank 44 simultaneously.Preferably, because 3 moment of vacuum disk are in rotary state, in order to ensure that each pore is all communicated with to prevent the generation of material casting phenomenon with a vacuum generator, in the present embodiment, make distance between the first vacuum tank 43 and the second vacuum tank 44 be less than the diameter of pore 31, thereby vacuum disk 3 turns to any position, at least all some overlaps with in two vacuum tanks one each pore 31, therefore can make each pore 31 all can connect with vacuum generator, thereby ensure that all suction nozzles, in the vacuum degree sucking after material, have avoided the material casting of suction nozzle.As in Fig. 4 45 point out be one of them pore 31 and just go between the first vacuum tank 43 and the second vacuum tank 44 time position signal, this position is a specific position, this pore 31 is connected with two vacuum tanks simultaneously.
In addition, be understandable that, vacuum disk 3 comprises rounded bottom surface 32 and the annular sidewall 33 that is arranged on rounded bottom surface 32 edges, motor 5 is arranged on vacuum disk 3 upper surfaces, motor 5 surrounds an annular groove with annular sidewall 33, vacuum annulus 4 is arranged in annular groove, and fits with the upper surface of rounded bottom surface 32.
In the course of the work, because the contact area of vacuum disk 3 and vacuum annulus 4 is little, thereby reduce the wearing and tearing between two parts, reduced the loss of part, thereby extended the useful life between whole device.
Although the present invention describes by specific embodiment, it will be appreciated by those skilled in the art that, without departing from the present invention, can also carry out various conversion and be equal to alternative the present invention.In addition, for particular condition or material, can make various amendments to the present invention, and not depart from the scope of the present invention.Therefore, the present invention is not limited to disclosed specific embodiment, and should comprise the whole execution modes that fall within the scope of the claims in the present invention.
