Braider polarity slewing arrangement
[technical field]
The utility model relates to the automatic taping-machine of electronic devices and components, and in particular, the utility model relates to a kind of braider polarity slewing arrangement that on braider, uses.
[background technology]
In order to use and convenient transportation, know the needs of equipment automatization manufacturing line assembling to adapt to the modernization point, the electronic devices and components general run of thins need carry out automatic tape package, so automatic taping-machine arises at the historic moment.For example, the SOT automatic taping-machine is the automatic tape package that is applied to secondary electrons components and parts such as diode, is to use the most general braider at present.The braid of electronic devices and components has strict polarity and both forward and reverse directions requirement, has the face of unified mark to be convenient to manufacturing line user's long-term use towards same direction.The secondary electrons components and parts of secondary components and parts SOT automatic taping-machine are vertically lined up through the vibration of the dish deflector chute that shakes, and get into straight line feeder.A plurality of vacuum cupss that device in straight line feeder deflector chute exit needs the circumferential outer rim of balance to be uniformly distributed with installation are drawn device repeatedly, and then through the relay mode device are drawn to that braid place is in place lays, behind the overlay film finished product; Because the device braid has strict polar requirement; Strict demand polarity is consistent, damaged part can not be arranged, and markd must be towards unanimity; Though and the face that the device that the straight line feeder biography is come can be realized mark is towards the top; But polarity anyway and the quality of device need strict the detection, and these two detections can only be transferred at balance and carry out synchronously in the device process, to increase work efficiency.
In view of the above problems; Automatic taping-machine electronics package polarity detecting device and various polarity control apparatus have appearred on the market; Wherein especially to use revolution to make reverse polarity material Rotate 180 ° the most general; The cost of this polarity slewing arrangement is higher, speed is slower, and material can fall down in the process of rotation, thereby has influence on work efficiency.
[utility model content]
The purpose of the utility model is effectively to overcome the deficiency of above-mentioned technology, and providing a kind of is the device that makes the rotation of material polarity, and this device is made simply, speed is fast, high efficiency.
The technical scheme of the utility model is achieved in that it comprises pedestal and is located at the rotating disk on the pedestal; Rotating disk is provided with some rotating disk indexing troughs; Its improvements are: a side of said rotating disk is provided with a polarity rotary seat; This polarity rotary seat is provided with the guide groove of a U-shaped, and two breach of this guide groove are provided with corresponding to two adjacent rotating disk indexing troughs, and two gap positions are provided with valve and optical fiber detector;
In the said structure, said polarity rotary seat is provided with a cover plate, also is provided with optical fiber detector on this cover plate.
The beneficial effect of the utility model is: the utility model is provided with corresponding to two adjacent rotating disk indexing troughs through two breach with the guide groove of U-shaped, and gap position is provided with valve and optical fiber detector, when material at gap position; And be reverse polarity need rotate to be straight polarity the time, the valve of a last indexing position can blow gas, and the valve of next indexing position produces pull of vacuum; Material forwards next indexing position blowing under the effect with guide groove of gas to along guide groove, and this moment, calibrated disc rotated a sub-degree angle simultaneously, and material is being blown, entered in the rotating disk indexing trough of next indexing position under the air-breathing effect; Optical fiber detector guarantees that material blows out and enter into fully in the rotating disk indexing trough from a last indexing position fully; Thereby accomplish the rotation of 180 ° of materials, make the reverse polarity material become the direction of straight polarity, the cost of the utility model is lower; And make simple; Speed is very fast simultaneously, and material can not drop from rotating disk, and work efficiency is higher.

[specific embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
With reference to Fig. 1, shown in Figure 2; The utility model has disclosed a kind of braider polarity slewing arrangement, and it comprises pedestal 1, is arranged on the rotating disk 2 on the pedestal, and rotating disk 2 is provided with some rotating disk indexing troughs 21; One side of rotating disk 2 is provided with a polarity rotary seat 3; This polarity rotary seat 3 is provided with the guide groove 31 of a U-shaped, and two breach of guide groove 31 are provided with corresponding to two adjacent rotating disk indexing troughs 21 on the rotating disk, and two gap positions are provided with valve 4 and optical fiber detector 5; Also be provided with a cover plate 6 on the polarity rotary seat 3, also be provided with optical fiber detector 5 on the cover plate 6.
Through said structure, material is in rotating disk indexing trough 21, when material is that reverse polarity is need rotate to be straight polarity the time; First indexing position is the valve meeting blow gas of first gap position; The next indexing position i.e. valve of second gap position produces pull of vacuum, and material rotates to second gap position along guide groove from first gap position under the effect of the power of blowing of gas and pull of vacuum, at this moment; Calibrated disc has rotated a sub-degree angle; In the entering rotating disk indexing trough, the effect of optical fiber detector is to guarantee that material blows out fully and gets into fully in the rotating disk indexing trough from a last indexing position to material, through said process under the effect of power of blowing and pull of vacuum; Material has also just been accomplished 180 ° rotation, is the direction that the material of reverse polarity has become straight polarity.
The preferred embodiment that is merely the utility model described above, above-mentioned specific embodiment are not the restrictions to the utility model.In the technological thought category of the utility model, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
