BACKGROUND
1. Technical Field
The present disclosure relates to feeders, particular to a label feeder.
2. Description of Related Art
A printed circuit board is often affixed with labels for identifying components or to show information about the printed circuit board. The labels are affixed to the printed circuit board manually. As such, the labels may pick up grease and other contaminants or the labels may be damaged during attachment
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
Referring to FIG. 1, a feeder 100 in accordance with one embodiment, is shown. The feeder 100 is capable of separating adhesive components 32 from a tap 30. The adhesive component 32 may be a label, an insulating plate, a cushion, for example. In the embodiment, the adhesive component 32 is a label. The adhesive components 32 are separately affixed on the tap 30 at intervals.
The feeder 100 includes a frame 10, a driven capstan device 12, a first idler roller 14, a second idler roller 16, a separating device 20 (see FIG. 2), a drive device 40, a detector 50, a controller 60, and a supporting platform 26.
The driven capstan device 12 and the separating device 20 are mounted to opposite ends of the frame 10. The first idler roller 14 and the second idler roller 16 are rotatably mounted to the frame 10, and positioned between the driven capstan device 12 and the separating device 20. The tap 30 winds around the driven capstan device 12, then is passed across the first idler roller 14, then is passed down the second idler roller 16 and is pressed by the second idler roller 16, and then transferred to the separating device 20 to separate the adhesive components 32 from the tap 30. The supporting platform 26 is adjacent to the separating device 20 and away from the second idler roller 16 to support each pealed adhesive component 32. The drive device 40 drives the tap 30 to transfer to the separating device 20. The detector 50 detects each pealed adhesive component 32. The controller 60 controls the drive device 40 to work when the detector 50 does not detect the peeled adhesive component 32.
The driven capstan device 12 includes two parallel blocking plates 120, and a capstan roller (not shown) rotatably connected between the two plates 120. The tap 30 winds around the capstan roller, and has a free end without the adhesive component 32. The two blocking plates 120 are blocked at opposite sides of the tap 30 to enable the tap 30 smoothly transferred to the separating device 20.
The first idler roller 14 and the second idler roller 16 are parallel to the capstan roller. The second idler roller 16 is adjacent to the separating device 20 and is positioned under the first idler roller 14. The first idler roller 14 is adjacent to the second idler roller 16.
Referring to FIG. 2, the separating device 20 includes a separator 22, and a tensioning member 24. The tensioning member 24 is secured to the middle of the separator 22. The tensioning member 24 is a strip board which is parallel to the first idler roller 14 and the second idler roller 16. Opposite ends of the tensioning member 24 are secured to the separator 22 via a pair of securing members 27, and capable of moving with respect to the securing members 27. A par of elastic members 25 are sleeved on the securing members 27, one end of the elastic member 25 contacts the tensioning member 24, and the other end of the elastic member 25 contacts the secured member 27, such that the tensioning member 24 is prevented from moving by the elastic member 25. The separator 22 is a rectangular board. There is a gap formed between the tensioning member 24 and the separator 22 to allow the tap 30 being transferred to the separator 22. One end of the separator 22 away from the tensioning member 24 sets a wedge shaped peeling bar 220.
Referring to FIG. 3, the drive device 40 of one embodiment is shown. The drive device 40 includes a drive motor 42 and a drive capstan device 44. The drive motor 42 and the drive capstan device 44 are secured to the frame 10 under the separator 22. The free end of the tap 30 is secured to the drive capstan device 44, such that the tap 30 turns sharply through an angle greater than 90 degree to cause one end of the lead edge of the adhesive member 22 to separate from the tap 30. The drive motor 42 drives the drive capstan device 44 to rotate via a belt 46, such the tap 30 is wound around the drive capstan device 44, and the tap 30 continues to be driven to unwind from the driven capstan device 12 and be advanced around the peeled bar 220, the adhesive component 32 becomes progressively peeled from the tap 30 and ultimately entirely separated from the tap 30.
Referring to FIG. 2 again, the supporting platform 26 includes three parallel supporting rollers 260 which are adjacent to the peeling bar 220. The supporting roller 26 is a screw shaft which has a circumferential ridge 262 around the surface of the supporting rollers 260. The supporting rollers 260 are positioned on a plane, and a supporting surface 264 coplanar with the surface of the separator 22 contacting the tap 30 is formed. The supporting surface 26 supports and presents the peeled adhesive component 32.
Referring to FIGS. 1 and 2 again, the detector 50 and the controller 60 are secured to the frame 10. The detector 50 is adjacent to the supporting member 26 and opposite to the separator 22. The controller 60 is adjacent the driven capstan device 12. The detector 50 generates a first control signal when the detector 50 does not detect the peeled adhesive component 32, and generates a second control signal when the detector 50 detects the peeled adhesive component 32. The controller 60 controls the drive motor 42 to work in response to the first control signal, such that the tap 30 can be transferred. The controller 60 controls the drive motor 42 to stop working in response to the second control signal, such that the tap 30 can not be transferred.
Even though relevant information and the advantages of the present embodiments have been set forth in the foregoing description, together with details of the functions of the present embodiments, the disclosure is illustrative only; and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
