There is hydraulic pressure support bar, is connected with levelling bench at the top of mechanical arm.
The mechanical arm includes lower arm and upper arm, and lower arm is straight line connecting rod, and upper arm is bent connecting rod, the lower arm with
It is connected between upper arm by first motor, hydraulic pressure support bar is also connected between lower arm and upper arm, what hydraulic pressure support bar provided pushes away
Power can support entire platform in the case where no motor torque.
The lower arm of the mechanical arm is connect by the second motor with pedestal, and hydraulic pressure support is fixed between lower arm and pedestal
Bar.
The upper arm of the mechanical arm connects levelling bench by servo motor.
The long 800mm of the straight line connecting rod of the mechanical arm, for bent connecting rod having a size of 700mm+750mm, bending angle is 135 °；
The high 500mm of levelling bench when mechanical arm is in home position, height when being elongated to extreme higher position can arrive 2500mm.
Safety barrier and operation panel are housed on the levelling bench, are equipped with interim book below the operation panel
Cabinet, user can input the call number of target books on operation panel, and browse required books, and desired books are put into and are faced
When bookcase in consult.
The levelling bench is equipped with attitude transducer, for being used after the posture of read level platform for MCU, MCU
Control servo motor makes levelling bench remain horizontal.
Working principle：When levelling bench is in extreme lower position, user can walk upper mounting plate, and target is inputted on operation panel
The call number of books, subsequent MCU retrieval navigate to the position of target books, the direction the x position of platform are adjusted by lead screw transmission,
The adjustment direction platform z position is rotated by motor, i.e., levelling bench is navigated into target books position, after reaching commitment positions,
Hydraulic pressure support bar supports entire platform, completes after consulting, levelling bench returns to initial position.
Beneficial effect：The present invention in such a way that two degrees of freedom mechanical arm positions can quickly and accurately positioning book, inspection
Suo Shuji speed greatly improves；Levelling bench highest can rise to 2500mm, can place large-scale bookshelf in library, improve space
Utilization rate.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is schematic diagram of the present invention in initial position；
Fig. 3 is schematic diagram of the present invention at extreme higher position.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Figure 1 to Figure 3, the present invention includes pedestal 1, bent connecting rod 2, interim bookcase 3, operation panel 4, levelling bench
5, servo motor 6, screw rod 7, hydraulic pressure support bar 8, first motor 9, straight line connecting rod 10 and the second motor 11.Pedestal 1 is a rotary table
Structure, base diameter 500mm, top bottom diameter are 350mm, and the bottom of pedestal 1 is connected with two screw rods 7, and two screw rods 7 pass through
Pedestal 1 is simultaneously embedded in floor, pedestal 1 can be driven to move horizontally when lead screw 7 rotates.The top of pedestal 1 passes through the second motor
11 connection mechanical arms, are further fixed on hydraulic pressure support bar 8, are connected with levelling bench at the top of mechanical arm between mechanical arm and pedestal 1
5。
Mechanical arm includes lower arm and upper arm, and lower arm is straight line connecting rod 10, and upper arm is bent connecting rod 2, straight line connecting rod 10 with it is curved
It is connected between bent connecting rod 2 by first motor 9, hydraulic pressure support bar 8 is also connected between lower arm and upper arm, hydraulic pressure support bar 8 mentions
The thrust of confession can support entire platform in the case where no motor torque.The lower arm of mechanical arm passes through the second motor 11 and bottom
Seat 1 connects, and hydraulic pressure support bar 8 is fixed between lower arm and pedestal 1.The upper arm of mechanical arm is connected horizontal flat by servo motor 6
Platform 5.
The straight line connecting rod 10 of mechanical arm is 800mm long, and for bent connecting rod 2 having a size of 700mm+750mm, bending angle is 135 °；
When mechanical arm is in home position, the height of levelling bench 5 is 500mm, and height when being elongated to extreme higher position can arrive
