  • Publication number: 20150040386
    Abstract: A mounting apparatus for securing a component in a cushion to a device and includes a receiving module, a fetching module, a control module, a positioning module, and a mounting module. The fetching module is moveable to catch the cushion. The positioning module includes a stage and a pair of positioning members. The pair of positioning members is moveable between a locked position in which the pair of positioning members is deviated from the stage. The cushion being located between the pair of positioning members and the stage and an unlock position in which the pair of positioning members is located on the stage to position the cushion. The mounting module secures the cushion on the stage to the device.

  • Publication number: 20150033523
    Abstract: A rivet binding and upsetting apparatus includes an operating platform, a feeding module, a pushing module, and a transmitting module. The operating platform includes a bottom plate. The feeding module includes a feeding portion for dispensing a rivet. The pushing module includes a receiving portion for receiving the rivet from the feeding portion. The transmitting module includes a rivet gun. The feeding module is moveable in a first direction substantially parallel to the bottom plate, to align the feeding portion with the receiving portion. The pushing module is moveable in a second direction substantially perpendicular to the first direction to align the receiving portion with the rivet gun for upsetting the rivet to bind the rivet in a mounting.

  • Patent number: 8474119
    Abstract: A blind-rivet gun includes a gun header, a cylinder, a piston, and an air saving device. The cylinder is separated from the gun header. The piston and an inner surface of the cylinder form a seal to divide the cylinder into a first air chamber and a second air chamber. The air saving device includes a switch circuit. The switch circuit turns on a first connection between the air inlet pipe and the first air outlet pipe or turns on a second connection between the air inlet pipe, the second air outlet pipe and the third air outlet pipe. The piston slides in the cylinder to generate inner high pressure by alternatively supplying high pressure air to the first air chamber or the second air chamber. The blind-rivet is pulled in and is pushed out of the blind-rivet ejecting pipe by the inner high pressure.
