Heavy equipment, heavy work methods, and heavy work solutions.

With the advancement of technology, electronic devices are changing with each passing day. For example, the operation interface of the electronic device has been developed from the traditional mechanical button control to the common touch screen.

In order to realize the possibility of a touch screen, the touch screen has a plurality of sensing lines on the glass, and the glass of the touch screen is expensive. Therefore, if there is a mistake in assembling the touch type electronic device, for example: When the glass of the touch screen is not properly mounted on the frame or display panel, it must be reworked.

The document of the Republic of China Patent Publication No. 200926470 refers to a method of reworking a touch display device.
