Description
Technical field
The utility model is related to the technical field of robot waterproof more particularly to a kind of skills of robot waterproof seal
Art field.
Background technology
The utility model devises the waterproof seal that a kind of and rainwear is used cooperatively, which is mounted in robot
On flange, then rainwear is sleeved in robot again, which includes two parts, and a part follows robot method
Orchid rotation, another part do not rotate, rainwear end are pressed on using nut on the part not rotated, in this way, robot
The rotation of robot flange will not drive rainwear, and in addition the plant bulk is larger, but also rainwear is in robot wrist
Section transitions are gentle, in this way, can increase robot allows slewing area, delay the rate of wear of rainwear, greatly reduce
Water penetrates into rainwear, can also promote the aesthetics of rainwear.
Currently, the problems of mainstream rainwear mainly has at 4 points in the market：1. due to the limitation of rainwear, the day of one's doom
Robot motion's range is made；2. liquid still can largely be penetrated into from robot flange, robot fault rate is still larger；3. preventing
The water jacket rate of wear is very fast；4. poor universality.
If rainwear is directly sleeved in robot, end on robot flange or additional shaft, that is, is prevented by beam mouth beam
6 axis of water jacket not transfer robot, rainwear and robot flange surface gap can be larger at this time, and liquid can largely be oozed by gap
Enter inside rainwear.
If rainwear is directly sleeved in robot, end is held tightly by anchor ear or other modes in robot flange or attached
Add on axis, i.e. 6 axis of rainwear transfer robot, when 5 axis, the movement of 6 axis, rainwear can reverse seriously, not only unsightly, also can
Service life is substantially reduced, in addition, still there can be gap at rainwear holding, that is, phenomenon of intaking can also exist；
Since the size disparity at 5 axis of robot flange face or additional shaft opposed robots is larger, thus herein rainwear compared with
Hardly possible design, and fold is more, intractable, when movement range is larger, rainwear can be pullled seriously, accelerated wear test.
In addition, rainwear currently on the market is substantially and is developed according to specific operating mode, when environment or machine
The posture slight variation of people some, then original rainwear using effect will substantially reduce, or damage too quickly.
