There are two types of loading modes, i.e. jacking cargo and crawl cargo for present invention tool.When need to transport goods size or weight compared with When reserving greatly and between cargo lower surface and ground the space that enough present invention drive into, the present invention transports goods using jacking part 3 Object can first use manpower or other equipment will if the insufficient space reserved between cargo lower surface and ground is driven into the present invention Cargo is moved on raising plate 3-19 of the invention;When transport goods size or weight it is smaller and between cargo lower surface and ground it is pre- When the insufficient space stayed is to allow the present invention to drive into, the present invention transports cargo using gripping portion;In addition shelf are jacked in the present invention During transport, the different articles on shelf can be placed into live difference according to field demand by mechanical arm handling module 403 Position realizes distribution of goods function, or the article of working site different location is grabbed on shelf, realizes that article picks up function Energy.
When being transported goods using jacking mode:
Firstly, driving first gear 2-2 to rotate in same direction, to make and first gear as shown in Fig. 2, driving wheel motor 2-1 is rotated forward The second gear 2-3 of 2-2 engagement is rotated backward (relative to the direction of rotation driving wheel motor 2-1), is connect with second gear 2-3 Drive shaft 2-4 is rotated backward (relative to the direction of rotation driving wheel motor 2-1), and wheel 2-6 is rotated backward therewith (relative to drive The direction of rotation driving wheel motor 2-1), by controlling the direction of rotation of four driving wheel motor 2-1, i.e., controllable wheel, thus real Existing all-around mobile of the invention, underface of transporting goods needed for reaching the present invention along certain path.
Secondly, jacking motor 3-4 is rotated forward as shown in Fig. 4, Fig. 5, Fig. 6, made separately by the chain 3-6 engaged with sprocket wheel 3-5 Sprocket wheel 3-5 synchronous rotary in one jacking module realizes that two the synchronous of jacking module rise, due in two jacking modules Portion's movement is identical, only illustrates wherein any one movement herein.
As shown in Fig. 4, Fig. 5, Fig. 6, jacking motor 3-4 is rotated forward, same therewith with the worm screw 3-7 of jacking motor 3-4 axis connection Step rotation drives worm gear 3-10 and the jacking module internal screw thread multi-diameter shaft 3-11 to link together with worm gear 3-10 to rotate forward, by It is welded on screw rod 3-20 in raising plate 3-19, leads and be welded on raising plate 3-19 at the top of rising stem 3-18, and lead rising stem 3-18 Lower end is placed in the relatively small through hole of the jacking upper end module housing top plate 3-2, and the rotary motion of screw rod 3-20 is limited with this, thus Make and the jacking module internal screw thread multi-diameter shaft 3-11 screw rod 3-20 being threadedly coupled and the jacking welded together with screw rod 3-20 Plate 3-19 is moved straight up, and until raising plate 3-19 jacks up cargo, jacking motor 3-4 stops rotating.
Again, by controlling the direction of rotation of four driving wheel motor 2-1, of the invention determining can be realized and move, make The present invention reaches target location along certain path.
Motor 3-4 reversion is jacked, the worm screw 3-7 synchronous rotary therewith with jacking motor 3-4 axis connection drives worm gear 3-10 And the jacking module internal screw thread multi-diameter shaft 3-11 reversion to link together with worm gear 3-10, to make and jacking module internal screw thread The screw rod 3-20 of multi-diameter shaft 3-11 threaded connection and the raising plate 3-19 welded together with screw rod 3-20 are moved straight down, Cargo is lowered, and until being placed to ground, jacking motor 3-4 stops rotating, and completes goods handling process.
When being transported goods using grasp mode:
Firstly, realizing all-around mobile of the invention by the direction of rotation for controlling four driving wheel motor 2-1, make the present invention It transports goods needed for being reached along certain path other designated position.
Secondly, gripping portion of the invention is started to work.Mechanical arm jacking module 401 controls mechanical arm translation according to demand Module 402 and mechanical arm handling module 403 reach the certain altitude (jacking in this module working principle and present invention jacking part Module is the same, is not described in detail herein).
Again, as shown in Figure 7, Figure 8, mechanical arm translation motor 4-2 is rotated forward, and will be moved by translation motor shaft coupling 4-4 It is transmitted on translation screw rod 4-7, makes to translate screw rod 4-7 synchronous rotation, to drive mobile station 4-6 to move forward, if mechanical arm translates Motor 4-2 reversion, then mobile station 4-6 is moved back, therefore can drive mechanical arm turret base 4- by control mechanical arm translation motor 10 translations, to realize that designated position is stretched out or be retracted into mechanical arm handling module 403.
Then, the motor work inside mechanical arm turret base 4-10, controls built-in retarder and transmits rotary motion On the turntable stretched out to mechanical arm pedestal 4-10, thus realize the rotary motion of mechanical arm turntable 4-11 in the horizontal direction, It is provided with revolute pair between mechanical arm shoulder 4-12 and mechanical arm large arm 4-13, passes through the motor in control mechanical arm large arm 4-13 Mechanical arm large arm 4-13 may be implemented and do pitching movement in vertical direction, the motor work inside mechanical arm ancon 4-14 can make Mechanical arm ancon 4-14 realizes pitching movement, and the motor being arranged inside mechanical arm forearm 4-15 realizes mechanical arm forearm 4-15 itself Rotary motion, reach specified position so as to control end effector 4-17.
When end effector 4-17 is electrical parallel clamping jaw, as shown in figure 11, the motor on parallel clamping jaw can control It rotates forward, two meshing gears is driven to relatively rotate, so that parallel clamping jaw clamped closed, grabs cargo;When end executes It when device 4-17 is magnechuck, as shown in Figure 10, is powered to magnechuck, so that it may which target goods absorption is got up;Work as end When actuator 4-17 is vacuum chuck, as shown in figure 12, target goods are adsorbed on vacuum chuck, complete by vacuum pump pumping Cargo crawl.
Then the present invention is moved to target position along scheduled path, after transfer robot stops movement, mechanical arm top Rising mould block 401 and mechanical arm translation module 402 move to specific position, and mechanical arm handling module 403 moves simultaneously, end is held Row device is moved to target point, when end effector 4-17 is electrical parallel clamping jaw, controls the motor reversal on parallel clamping jaw, band Dynamic two meshing gears, so that parallel clamping jaw unclamps, place goods onto target position backwards to rotating, then of the invention Gripping portion movement is withdrawn, and transfer robot is removed, and completes the whole process that cargo is grabbed and transported.
The present invention can also be performed material and distribute operating mode, i.e., the underface of the invention for moving to shelf position, Shelf are jacked up using jacking part, transfer robot is moved according to given line, when the position for moving to material in need When setting, the material on shelf is grabbed designated position, then transfer robot continues to move to, and goes next by gripping portion work Distribute material in a position.
Material pickup work mode can also be performed in the present invention, i.e., the underface of the invention for moving to shelf position, Shelf are jacked up using jacking part, transfer robot is moved according to given line, when moving to material to be picked up When position, gripping portion work is grabbed material to be picked up on shelf, then transfer robot continues to move to, and goes next Pick up material in position.
