Title: Attachment device

Description:
FIELD 
     The present disclosure relates to an attachment device. 
     BACKGROUND 
     Conductive adhesive films usually ground electronic devices. When assembling, the conductive adhesive film is first adhered to an attachment device, and then the conductive adhesive film is assembled to the electronic device. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views. 
       The FIGURE is a schematic, isometric view of an attachment device according to an exemplary embodiment of the present disclosure. 
     
    
    
     DETAILED DESCRIPTION 
     The FIGURE illustrates an attachment device  100 . The attachment device  100  is configured for attaching a conductive adhesive film  200  to an electronic device. In this embodiment, the conductive adhesive film  200  is a conductive fabric. The conductive fabric includes a cloth coated with conductive glue. 
     The attachment device  100  includes an exhaust  110 , a connecting pipe  120  and an adhering head  130 . The connecting pipe  120  is made of stainless steel and forms an airtight connection between the exhaust  110  and the adhering head  130 . 
     The shape of the adhering head  130  corresponds to the shape of the conductive adhesive film  200 . In this embodiment, the conductive adhesive film  200  is square, and the adhering head  130  is a hollow cube. The adhering head  130  includes a connecting surface  131  and an adhering surface  132  opposite to the connecting surface  131 . The connecting surface  131  defines a connecting hole connected airtight to the connecting pipe  120 . 
     The adhering surface  132  is a flat surface, and defines a number of evenly spaced adhering holes  132   a.  The adhering holes  132   a  are equal to each other. The adhering holes  132   a  form an array on the adhering surface  132 . In another embodiment, when the conductive adhesive film  200  is round, the adhering holes  132   a  can also be distributed circularly. 
     The size of the adhering holes  132   a  is determined by the height of the conductive adhesive film  200  for avoiding forming wrinkles on the conductive adhesive film  200  when the conductive adhesive film  200  is adhered on the adhering surface  132 . In this embodiment, the height of the conductive adhesive film  200  is about 0.05 millimeters, the adhering holes  132   a  forms a 4×4 array, and the diameter of each adhering hole  132   a  is about 1 millimeter. 
     The adhering head  130  is made of rigid material, such as white polyoxymethylene (POM). The adhering head  130  will not deforms when adhering the conductive adhesive film  200 . 
     When in use, the exhaust  110  creates a vacuum in the adhering holes  132   a  and the adhering holes  132   a  absorb the conductive adhesive film  200 . As the adhering holes  132   a  are evenly spaced, the adhering strength of the adhering holes  132   a  will be evenly applied on the conductive adhesive film  200  for avoiding wrinkles from being formed on the conductive adhesive film  200 . 
     It will be understood that the above particular embodiments are shown and described by way of illustration only. The principles and the features of the present disclosure may be employed in various and numerous embodiments thereof without departing from the scope of the disclosure. The above-described embodiments illustrate the scope of the disclosure but do not restrict the scope of the disclosure.
