20140283629 | KEYBOARD TESTING MACHINE - A keyboard testing machine for testing a keyboard of an electronic apparatus is provided. The keyboard testing machine includes a rack, a fixing base, and a pressing module. The fixing base is operatively connected to the rack and located over the electronic apparatus. The pressing module is located over the keyboard and includes a drive shaft, a rotating member, and a pressing assembly. The drive shaft is rotatably disposed on the fixing base. The rotating member is sleeved onto the drive shaft and has a cam portion. The pressing assembly is operatively connected to the fixing base and the cam portion. When the drive shaft rotates together with the rotating member, the cam portion drives the pressing assembly to linearly move relative to the fixing base, so as to make the pressing assembly cyclically press the keyboard. | 09-25-2014 |
20140305231 | KEYBOARD TESTING MACHINE - A keyboard testing machine for testing a keyboard of an electronic apparatus is apparatus. The electronic apparatus is carried on a conveyor. The keyboard testing machine includes a rack, a 3D movement apparatus, a linear encoder, a first driving module, and a pressing module. A first slide rail of the rack is parallel to the conveying direction of the conveyor. The 3D movement apparatus is slidably disposed on the first slide rail. The linear encoder is used to detect the conveying speed of the conveyor. The first driving module is disposed on the rack for driving the 3D movement apparatus to move along the first slide rail with the conveying speed. The pressing module is operatively connected to the 3D movement apparatus. The 3D movement apparatus makes the pressing module press the keyboard, and moves the pressing module along a pressing path relative to the keyboard. | 10-16-2014 |
