1. Technical Field
The present disclosure relates to a device for detaching a cover from a base.
2. Description of Related Art
During manufacturing, electronic devices may include a cover and a base that are connected together by an adhesive tape, and the cover needs to be detached from the base when reworking some of the electronic devices. Thus, there is a need to provide a device to quickly and completely detach the cover from the base.
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.
Embodiments of the present disclosure will be described with reference to the accompanying drawings.

The support frame 20 is secured to the top surface of the platform 10. The driving unit 30 is secured to the support frame 20, and includes a rod 31 that can move toward and away from the platform 10. In the embodiment, the driving unit 30 is a pneumatic cylinder.
The suction member 40 is connected to the lower end of the rod 31, and defines a cavity 41 and has a connector 43 communicating with the cavity 41. The cavity 41 is covered by a suction plate 45. The suction plate 45 defines a number of through holes 451 that communicate with the cavity 41. The connector 43 is connected to a vacuum source 60 via a pipe 47. The suction plate 45 can move toward the platform 10 to a position where the suction plate 45 is in contact with the top surface of the cover 220 of the electronic device 200, the through holes 451 then being covered. The air can be drawn out of the cavity 41 through the connector 43, thereby creating a vacuum in the cavity 41. The cover 220 can thus be drawn by negative air pressure to the suction plate 45.
The detaching device 100 further includes a heating element 50. The heating element 50 heats and softens the adhesive tape 230, thereby weakening the bond between the base 210 and the cover 220, and allowing the cover 220 to be released from the base 210. The cover 220 is thus detached from the base 210.
In the embodiment, the heating element 50 includes a heating wire 51 and a thermally conductive pad 53. The heating wire 51 is embedded in the suction plate 45, and the thermally conductive pad 53 is secured to the suction plate 45 and covers the heating wire 51. The thermally conductive pad 53 transfers the heat generated by the heating wire 51 to the cover 220.
In the embodiment, the detaching device 100 further includes a magnet 70. The magnet 70 is secured to the suction plate 45, and is arranged in such a way that the magnet 70 is located above the ferromagnetic metal 270 when the suction plate 45 is in contact with the cover 220. The magnet 70 attracts the ferromagnetic metal 270, which allows the ferromagnetic metal 270 to move upward together with the cover 200.
While various embodiments have been described and illustrated, the disclosure is not to be construed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the present disclosure as defined by the appended claims.
