The invention discloses an auto-
coupling welding and packaging mechanical device of a coaxial-type optical transceiving device, which comprises a
workbench, an aligning unit, a lifting unit, a propelling unit, a manual lower fixture, a
welding unit, a swinging unit, an upper fixture, an equipment housing and a control button, wherein an aligning unit base platform, the propelling unit and a
welding workbench are installed on an equipment
workbench; the propelling unit comprises a left propelling device and a right propelling device which are distributed in an angle of 45 DEG around a rotating shaft of a Theta z r autorotation platform; the manual lower fixture is placed on the left propelling device; the lifting unit is installed on the Theta z rotating platform; the welding unit and a portal-type frame are installed on the welding workbench, and the welding unit comprises three welding devices which are uniformly disturbed in an angle of 120 DEG around the rotating shaft of the Theta z autorotation platform; the swinging unit is installed on the portal-type frame; a Z-axis automatic linear
slipway is installed on a swinging plate of the swinging unit; the upper fixture is installed on the Z-axis automatic linear
slipway, and can realize pitching actions by depending on the action of the swinging unit; the equipment housing is installed on the equipment workbench; and the control button is installed on the equipment housing. The auto-
coupling welding and packaging mechanical device has the advantages of reasonable and ingenious structural design, strong extendibility, space economization, high degree of
automation, convenience for control, simpleness in operation and short
operation time, therefore the cost of products is low and the quality is stable; and the problems of
coupling, aligning and welding of the coaxial-type optical transceiving device are effectively solved, and the requirements of an industrialized
production line are satisfied.
