It is good fit, thus increase the dependence programmed to mechanical arm Collaborative Control.
The flat folder adaptive robot hand (patent US8973958B2) of another multi link, including five connecting rods, spring, electricity
Machine etc., the arrangement achieves the flat folders of circular arc and self-adapting grasping pattern.The device can not only realize grip and gripping, and pinch
During holding, the second segment remains the posture constant relative to pedestal, has reached good parallel clamping grasp mode
(referred to as flat gripper take), this grasp mode are particularly suitable for sheet goods of the crawl on work top (desktop), even this
Unique grasp mode in the case of kind (other than going absorption using sucker).In addition, the robot can also object compared with
The stabilization envelope for being contacted object when big using two segments is captured, which obtains the shape closing more more stable than parallel clamping
Effect is captured, this is to capture the more contact points crawl that must be used when heavy objects.At work, which first keeps end
Segment opposite base posture is constant, carries out the translation of arc track, achievees the effect that flat folder, or realizes that adaptive envelope is grabbed
It takes.Disadvantage is that:The device is a kind of circular arc translation end segment in the flat folder stage, cannot achieve linear translation end
Segment needs mechanical arm coordinated when various sizes of sheet goods being clamped on the table, to adjust the position of robot
It sets, to increase control difficulty, is unfavorable for high-speed flexible crawl.
Have the robot (patent WO2016063314A1) of linear translation clamping, including pedestal, motor, transition second
Transmission mechanism, the first segment, the second segment, eight connecting rods, multiple shafts etc..The device can realize that the straight line of the second segment is flat
It is dynamic, the function of straight line parallel clamping is realized to object using the straight line parallel movement of the second segment.Disadvantage is that:The dress
It sets and is only capable of realizing straight line parallel clamping function, cannot achieve the function of adaptive envelope crawl.

It is known:∠ EOA=α, AB/AE=tan (pi/2-α), EA ⊥ AB, at a time, point E1、A1、B1Respectively point E,
A, B post exercises current point, point E1It is translatable on straight line EO, corresponding, A1It is accordingly translatable on straight line OA, will be proven below point B1
Be translatable on straight line BO, and straight line BO vertically with straight line EO.
Q EA⊥AB.
∴ line segments EB is the diameter of a circle of 3 points of passing point E, A, B
QAB/AE=tan (pi/2-α)
∴ ∠ EBA=α (1)
Q ∠ EOA=α (2) again

4 points of concyclic of ∴ points O, E, A, B
Remember ∠ AEB=β, has:β=pi/2-α
According to " angle of circumference of identical chord length is equal ",
Then 4 points of point O, E, A, B concyclic middle corresponding chord length AB ∠ AOB=∠ AEB=β,
And a line of β is fixed straight line AO,
Therefore the another a line of β be straight line BO, BO be it is fixed,
That is B1Put the on straight line BO always
Q alpha+betas=pi/2,
∴BO⊥EO.

Line is translatable, as shown in Figure 9;Sliding block 5 accordingly slides on slide bar 12, and the second motor 61 does not rotate at this time, by the second driver
Structure 62 so that 43 opposing slider 5 of lower link does not rotate, and lower link 43 is constant relative to 1 posture of pedestal, because parallel four
The relationship of side shape ABCD, the second segment 22 (i.e. line segment BC) keep parallel with lower link 43 in the process, to which second refers to
Section 22 is constant relative to the posture of pedestal 1, reaches the function of straight line parallel clamping, and object 10 on the table is put in suitable crawl
(be in this case unique grasp mode).
In above process, if the second segment 22 first contacts object 10, stop grabbing sensor 72 and obtain signal, control mould
Block 8 sends out instruction, and by first motor drive module 91 so that first motor 11 stalls, crawl terminates.Reach and has been referred to second
Section 22 contacts the grasp mode of the straight line parallel clamping object of object 10.Action process is as shown in Figure 10.
In above process, if the first segment 21 first contacts object 10, trigger sensor 71 obtains signal, controls mould
Block 8 sends out instruction, by first motor drive module 91 so that first motor 11 stalls, is made by the second motor drive module 92
The rotation of the second motor 61 is obtained, the second transmission mechanism 62 (retarder 620, worm screw 621, worm gear 622, transition axis 623, first are passed through
Transition gear 624, the second transition gear 625) so that lower link 43 is rotated around nearly joint shaft 31, it is driven by rear link 44
Second segment 22 is gone the long way round the rotation of joint shaft 32, until the second segment 22 also contact object 10, is stopped grabbing sensor 72 and is obtained signal, control
Molding block 8 sends out instruction, and by first motor drive module 91 so that first motor 11 stalls, crawl terminates.Reach with
One segment 21 and the second segment 22 contact the grasp mode of the self-adapting grasping object of object 10 simultaneously, which can be certainly
The dynamic object for adapting to different shape, size, there are two contact points for tool, and grasp force is big and crawl is more stable, is suitble to crawl heavier
Different objects.Action process is as shown in figure 11.
When discharging object 10, control module 8 sends out instruction, allows the second motor 61 to invert, is made by the second transmission mechanism 62
Lower link 43 inverts, and 10 surface of object is left in the reversion of the second segment 21, while first motor 11 inverts, and passes through the first driver
Structure 61 makes 21 corresponding sports of intermediate connecting rod 42 and the first segment, the first segment 21 leave 10 surface of object, parks sensing when first
Device 731 obtains signal, stops first motor 11;When second parks sensor 732 and obtain signal, stop the second motor 61, release
Terminate, which is returned to initial position.
Reset signal is received, control module 8 executes the pattern of above-mentioned release object, repeats no more.
Utility model device utilizes 4 points of concyclic linkage rod slide block mechanisms, multiple sensors, control module and two motors
Deng the comprehensive compound grasp mode for realizing straight line parallel clamping and the crawl of adaptive envelope.According to target object shape and position
Difference, object can be clamped outside linear translation the second segment, can also open support from the inside and take hollow object, also
The object that the first segment and the second segment go envelope crawl different shape, size with two segment contacts can be rotated successively;Crawl
The demand to control system is reduced when the different size sheet goods being positioned on workbench, without being carried out for different objects
Complicated program, crawl range is big, grasping stability;Manufacture is low with maintenance cost, is suitable for robot.
