BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure relates to a device for removing burrs from workpieces. 
         [0003]    2. Description of Related Art 
         [0004]    Workpieces may have burrs formed thereon from manufacturing processes. However, it is time-consuming to remove the burrs manually and one-by-one. 
         [0005]    Therefore, it is desirable to provide a burr-removing device for removing burrs from workpieces to overcome the limitations described.

     DETAILED DESCRIPTION 
       [0013]    The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.” 
         [0014]      FIGS. 1-3  show an exemplary embodiment of a device  10  for removing burrs  21  from workpieces  20 . The device  10  comprises a supporting plate  11 , an ejector plate  12 , and a press plate  13 . The supporting plate  11 , the ejector plate  12 , and the press plate  13  can be made of, but are not limited to be made of, stainless steel, iron, and/or copper. 
         [0015]    The supporting plate  11  is configured for supporting the workpieces  20 . The supporting plate  11  is substantially square. The supporting plate  11  comprises a first surface  102  and a second surface  104  opposite to the first surface  102 . The supporting plate  11  defines a plurality of holding holes  110  in the first surface  102  and defines a plurality of through holes  111  in the second surface  104 . Four first location units  112  are formed at four corners of the supporting plate  11  respectively. Each holding hole  110  receives one corresponding workpiece  20 . The through holes  111  communicate with corresponding holding holes  110 . In one embodiment, one holding hole  110  communicates with two through holes  111 . The supporting plate  11  is connected to the ejector plate  12  and the press plate  13  by the first location units  112 . Each first location unit  112  comprises a location pole  1120  and defines a location hole  1121 . The location poles  1120  correspond to the press plate  13 . Each location pole  1120  is substantially coaxial with the corresponding location hole  1121 . 
         [0016]    A shape of the ejector plate  12  is substantially the same as a shape of the supporting plate  11 . The ejector plate  12  comprises a plurality of pins  120  and four second location units  121 . The four second location units  121  correspond to the four first location units  112  one-to-one. Each second location unit  121  is received in one corresponding location hole  1121 , and each pin  120  is received in one corresponding through hole  111  of the supporting plate  11 . 
         [0017]    A shape of the press plate  13  is substantially the same as the shape of the supporting plate  11 . The press plate  13  forms a plurality of pressing posts  130  and four third location units  131 . The four third location units  131  correspond to the four first location units  112  one-to-one. The pressing posts  130  remove the burrs  21  when the press plate  13  is assembled to the supporting plate  11 . 
         [0018]    Referring to  FIGS. 4-5 , in use, the workpieces  20  are received in the holding holes  110 , such that the burrs  21  face the press plate  13 . The press plate  13  is assembled to the supporting plate  11 , such that the third location units  131  receive the location poles  1120  of the first location unit  112 . As the press plate  13  is assembled to the supporting plate  11 , the pressing posts  130  resist against the burrs  21  of the workpieces  20  and break the burrs  21  off from the workpieces  20 . After the burrs  21  are removed, the press plate  13  is removed from the supporting plate  11 . The ejector plate  12  is assembled to the supporting plate  11 , such that the pins  120  are received through the through holes  111 . The pins  120  eject the workpieces  20  from the holding holes  110  of the supporting plate  11 . 
         [0019]    The device  10  uses the pressing posts  130  to remove the burrs  21  from the workpieces  20 . The press plate  13  can remove the burrs  21  from many workpieces  20  simultaneously, and the ejector plate  12  can eject the many workpieces  20  simultaneously. Thus, the device  10  saves time and is easy to use. 
         [0020]    In other embodiments, the location poles  1120  protrude toward the ejector plate  12 . Numbers and arrangements of the first location unit  112 , the second location unit  121 , and the third location unit  131  can be changed according to actual needs. 
         [0021]      FIG. 6  shows a second exemplary embodiment of a device  30  for removing burrs  21  from workpieces  20 . The device  30  of  FIG. 6  is similar to the device  10  of  FIGS. 1-5  except that the device further comprises a heating unit  14 . 
         [0022]    The heating unit  14  is configured for heating the pressing posts  130  of the press plate  13 . The heated pressing posts  130  can soften the burrs  21  to easily remove the burrs  21  from the workpieces  20 . 
         [0023]    The heating unit  14  also can be made of, but is not limited to be made of, stainless steel, iron, and/or copper. 
         [0024]    It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely exemplary embodiments of the disclosure.
