Background technology
Implement to automate using digital calculation balance and weigh one of research hotspot for having become robot field.The prior art
The advantages of weighing is mostly static using balance, the relative motion mode that crucible declines, this mode is that the zeroing time of balance is short.
It is identical with crucible gravity direction however, as crucible decline acceleration, it is far longer than oneself of crucible so as to cause impact force at contact
Weight, i.e., for sensibility reciprocal precision is the digital calculation balance of 0.1mg, huge impact force leads to the data wave of balance during weighing
The dynamic time is too long, weighs inefficient.Therefore, designing a kind of weighing robot for significantly reducing the balance data fluctuations time has
Very useful value.
Invention content
The technical issues of present invention need to solve be：For technical problem of the existing technology, the present invention provides a kind of high
Precision weighs solid powder, impact force at contact is reduced by digital calculation balance elevating movement, significantly shortens the balance data fluctuations time
The high-precision of low power impact force quickly weigh robot.
To solve the above-mentioned problems, solution proposed by the present invention is：A kind of high-precision of low power impact force quickly claims
Robot is measured, it includes being installed in, and linear motion on U-shaped frame is secondary and ball screw assembly, digital calculation balance and is positioned on crucible tongs
Crucible, the motor being connected with the ball screw assembly, places in the crucible and needs the solid powder weighed.
The linear motion it is secondary with the ball screw assembly, along vertical direction installed parallel；The linear motion is secondary to be included directly
Line guide rail and sliding block, the ball screw assembly, include lower end pass through bearing be installed in leading screw on lower carriage and with the leading screw phase
The nut of cooperation.
The balance base is equipped with the groove of bigger about described digital calculation balance bed-plate dimension, is installed in and subtracts in the groove
Shake spring, and the sensibility reciprocal precision of the digital calculation balance is 0.1mg, is placed horizontally on the shock-absorbing spring；The digital calculation balance
Weighing plate top is installed with weighing bar；The underface that bar is located at crucible is weighed, the crucible tongs are equipped with circular through hole, the earthenware
Crucible is positioned in the circular through hole.
Further, the rigidity of the shock-absorbing spring is 20~30N/mm.
Further, the circular through hole on the crucible tongs is stepped circular through hole, and upper part Circularhole diameter is slightly less than
The maximum outside diameter of the crucible, lower part Circularhole diameter are slightly larger than the minimum diameter of the crucible.
Further, the digital calculation balance more than two on the balance base can be set, can be set on the crucible tongs
Put the crucible identical with the digital calculation balance quantity.
Further, stop at the weighing bar ascending motion to the crucible bottom 0.5mm, then the weighing bar exists
The lower jack-up crucible of elongation strain effect of the shock-absorbing spring makes it completely disengage the crucible tongs.
Compared with prior art, the present invention having the following advantages that and advantageous effect：
(1) a kind of high-precision of low power impact force of the invention quickly weighs robot, is fixed by crucible, and balance rises
Relative motion mode implement to weigh, by balance rise acceleration cancel out each other with its own gravity, so as to reduce weighing bar
With the impact force at contact of crucible.
(2) a kind of high-precision of low power impact force of the invention quickly weighs robot, by setting shock-absorbing spring
Significant compressive deformation occurs in digital calculation balance uphill process, so that weighing bar stop motion when to touch crucible.
It follows that the data fluctuations time shows during the weighing robot of the present invention has smaller impact force at contact, balance weighs
It writes and reduces, weigh efficiency and significantly improve.

Specific embodiment
The present invention is described in further detail below with reference to the drawings and specific embodiments.
Shown in Figure 1, a kind of high-precision of low power impact force of the invention quickly weighs robot, including being installed in U
Linear motion pair and ball screw assembly, digital calculation balance 5 and the crucible 9 being positioned on crucible tongs 8 in type frame 1, with ball-screw
The connected motor 34 of pair, interior place of crucible 9 need the solid powder weighed.
It is shown in Figure 1, linear motion it is secondary with ball screw assembly, along vertical direction installed parallel；Linear motion is secondary to be included directly
Line guide rail 20 and sliding block 21, ball screw assembly, include lower end pass through bearing be installed in leading screw 30 on lower carriage 32 and with leading screw 30
Matched nut 31；
Shown in Figure 1, balance base 4 is equipped with the groove of bigger 5 bed-plate dimension of about digital calculation balance, is installed in groove
Shock-absorbing spring 6, the sensibility reciprocal precision of digital calculation balance 5 is 0.1mg, is placed horizontally on shock-absorbing spring 6；The weighing plate of digital calculation balance 5
Top, which is installed with, weighs bar 7；The underface that bar 7 is located at crucible 9 is weighed, crucible tongs 8 are equipped with circular through hole, and crucible 9 is positioned over
In circular through hole.
As preference, the rigidity of shock-absorbing spring 6 is 20~30N/mm.
As preference, the circular through hole on crucible tongs 8 is stepped circular through hole, upper part Circularhole diameter is slightly less than earthenware
The maximum outside diameter of crucible 9, lower part Circularhole diameter are slightly larger than the minimum diameter of crucible 9.
As preference, digital calculation balance 5 more than two can be set on balance base 4, can be set on crucible tongs 8 and number
The identical crucible 9 of 5 quantity of balance.
As preference, motor 34 drives leading screw 30 to rotate forward, and then balance base 4 and digital calculation balance 5 is driven to rise
Movement, during ascending motion, compressive deformation occurs digital calculation balance 5 for shock-absorbing spring 6, and compression deformation is 3mm or so；Claim
Stop at 7 ascending motion of gauge rod to 9 bottom 0.5mm of crucible, weigh bar 7 and then pushed up under the elongation strain effect of shock-absorbing spring 6
Playing crucible 9 makes it completely disengage crucible tongs 8.
The course of work and operation principle：First, the crucible 9 equipped with solid particle to be weighed is positioned over to the circle of crucible tongs 8
Kong Zhong；Then, motor 34 drives leading screw 30 to rotate forward, and then drives balance base 4, digital calculation balance 5 and weigh bar 7 and rise,
Stop at the corresponding 9 bottom 0.5mm of crucible of distance from top of bar 7 until weighing；In 5 uphill process of digital calculation balance, shock-absorbing spring 6 is sent out
Raw compressive deformation, deflection are 3mm or so；After motor 34 stops, shock-absorbing spring 6 is restored to initial length, so as to weigh bar 7
Crucible 9 is jacked up, crucible 9 is made to completely disengage crucible tongs 8 and prepares to weigh；Effect and digital calculation balance 5 due to shock-absorbing spring 6 is upward
The acceleration of movement is cancelled out each other with its own gravity, and the impact force at contact for weighing the jack-up crucible 9 of bar 7 is only 9 gravity of crucible
2 times or so, impact force at contact when declining compared to the static crucible of balance is 5 times or more of crucible gravity, therefore digital calculation balance 5
The data fluctuations time during weighing significantly reduces, so as to shorten the weighing time.
