The specific embodiment
In Fig. 1, schematically illustrate 6 shaft industrial robots.Yet clearly the utility model is not limited to this robot, but possibly be used to have more or less robot.Illustrated robot has the frame 1 that rotatably is assemblied on the pedestal 2, and this pedestal makes frame 1 rotate around vertical first manipulator shaft.Following robot arm 3 is connected to frame and around the second manipulator shaft pivotal connection.Following robot arm 3 supports the upper arm 4 of robot.Following robot arm and last robot arm are around the 3rd manipulator shaft pivoted.Last robot arm 4 can rotate around the 4th manipulator shaft.Upper arm 4 supports wrist part 7 in its outer end, and said wrist part comprises can around the inclination part 8 of the 5th manipulator shaft rotation and support can be around the instrument attached peripheral device 9 of the 6th manipulator shaft rotation.End effector 10 such as the annex of soldering appliance or other expectations can be assemblied on the instrument attached peripheral device 9.In order to drive the part that is connected in axle rotation separately, motor and necessary transmission device are provided.Along the aforesaid flexible conduit 5 of robot arm 4 assemblings.In flexible conduit 5, be laid with necessary wiring, exit opening 12 is passed at this place, the inner that is routed in upper arm 4, on the upper arm next door, and up to instrument attached peripheral device 9.Exit opening 12 is concentric with the first rotating shaft A.Can with the wiring further cloth be made as pass in the instrument attached peripheral device with the 3rd rotating shaft C concentric openings in the instrument attached peripheral device.
Other parts of the wiring of cable bag and necessity do not illustrate, but they can and be assemblied in robot part inside or outside in varying degrees according to combining form.In illustrated robot type, upper arm 4 has to be positioned at and departs from upper arm rotating shaft and the part parallel with this, and this is called as the first rotating shaft A below upper arm rotating shaft.
In Fig. 2 to Fig. 6, illustrate robot arm in more detail according to the utility model.Robot arm 4 comprises arm part 6 and wrist part 8.This arm part can rotate around the first rotating shaft A.Be provided with in the outer end of arm part 6 and comprise and be used for intersecting also shape at an angle that the second rotating shaft B is perpendicular to the first rotating shaft A in illustrated embodiment around wrist part 8, the second rotating shaft B of the tilt function of second rotating shaft B rotation and the first rotating shaft A.Far-end at wrist part 8 is connected with instrument attached peripheral device 9, and instrument attached peripheral device 9 can be rotated around the second rotating shaft B pivot through the wrist part, and instrument attached peripheral device 9 can be rotated around the 3rd rotating shaft C equally.The 3rd rotating shaft C can depend on the pivot angle of wrist part 8 and aim at the first rotating shaft A or intersect with the first rotating shaft A.Usually, the first rotating shaft A and the 3rd rotating shaft C will be positioned at same vertical plane.Instrument attached peripheral device 9 can comprise so-called rolling disc (turning disc) and/or tool, on them, is equipped with actual tool 10.
Guide the flexible conduit 5 that is used to connect up with flexible pipe at wrist part 8 places through guide member 14, guide member 14 is attached to the wrist part via attached peripheral device.In Fig. 3 and Fig. 4, illustrate guide member 14 in more detail.Guide member 14 is designed to have the basic sleeve-shaped of two openends, and its suitable flexible conduit 5 passes guide member.The inside of guide member 14 is designed to the free axially-movable of the flexible conduit 5 in the guide member, and is used for the motion that rotates freely of the interior flexible conduit of guide member.In order under the situation of not damaging flexible conduit, to promote the bending of flexible conduit, the inlet opening 15 of guide member can have conical interior shape.Through this conical interior shape, when flexible conduit is crooked at the some place that gets into guide member, bigger bending radius and littler wearing and tearing and the advantage of tension force on flexible conduit, have been obtained.If expectation, guide member 14 can also have conical interior shape at the end that flexible conduit leaves guide member for the same reason.
In Fig. 3, Fig. 4 and Fig. 5 in the illustrated embodiment, for the end of flexible conduit 5 provides terminal protective device 16.Terminal protective device is designed to two sleeve pipes; It comprises inner sleeve part 17 and outer tube part 18; This inner sleeve part is connected through end wall 19 with the end of outer tube part at them; Thereby made the 20 last times of end that are mounted to flexible conduit 5 when terminal protective device that the end of flexible conduit was in abutting connection with said end wall and thereby be protected in pair sleeve pipes.Alternatively, terminal protective device can be described to outer tube part 18, and an end of this outer tube part is inwardly turned up and thereby formation end wall 19 and inner sleeve part 17.
Terminal protective device 16 in the illustrated embodiment also has second function, and this second function is as arresting stop, and this arresting stop prevents that flexible conduit 5 from can be extracted from guide member 14.For this purpose, in case having on the end that is mounted to flexible conduit, terminal protective device 16 prevents that it is inserted into the outer shape of guide member.In illustrated example, in the face of the free end 22 of the outer tube part 18 of guide member when attempting that flexible conduit pulled out guide member backward, serve as the flange that stops near the associated end 23 of guide member.
Robot arm according to the utility model also comprises the maintenance equipment 26 that is used for flexible conduit 5; This maintenance equipment 26 is disposed in exit opening 12 places of the inner of robot arm 4; This place's flexible conduit from the inside of robot arm withdraw from, as shown in Figure 6.This maintenance equipment 26 is designed to make it to allow rotating freely of the interior flexible conduit 5 of maintenance equipment, and at the same time, it prevents the axially-movable of flexible conduit.Therefore, arm part 6 can rotate freely about flexible conduit 5 equally.Can be in the example that obtains to be used to be assemblied in the maintenance equipment 26 on the flexible conduit with corrugated outer shape on the market with above-mentioned functions.This maintenance equipment also can be designed to make it be minimized in the wearing and tearing on the flexible conduit, and thereby serves as protective cannula.
The utility model should not be limited to shown example and embodiment, but can as will being recognized by those skilled in the art, in the scope of appended Patent right requirement book, be revised in every way.
