Description

Battery system mounting structure of AGV floor truck is selected in relay

Technical Field

The invention relates to the field of mechanical equipment, in particular to a storage and sorting AGV carrying trolley.

Background

The rise in the field of e-commerce logistics has brought about a lot of equipment for producing and packaging in storage and express delivery.

The storage relay sorting AGV is a conveying vehicle for the storage relay sorting and conveying industry, takes a rechargeable storage battery as a power source, is controlled by a computer, and is provided with a microprocessor and conveying equipment for controlling the advancing route and the behavior of the conveying equipment.

Relay picking: 1) the AGV accepts the scheduling instructions to the edge of the item to be picked. 2) An operator scans a code to pick up goods and picks up the goods in the AGV carrying box. 3) The operator presses the confirmation key, the AGV walks to the next commodity edge needing to be selected, the operator places the secondary commodities in the AGV carrying box, and the operation is repeated in this way, so that the commodities in one order are sorted completely.

Compared with a goods-to-person AGV picking mode, the relay picking mode has the advantages that 1) the hit rate is high, goods are taken manually, and the accuracy is high. 2) The sorting efficiency is high. 3) The AGV trolley bears less commodities each time and has low power consumption. And power components such as a motor reducer and the like have long service life.

Common warehousing AGV drive suspension systems are known from CN208306795U, CN 208682542U. The AGV suspension structure that CN208306795U announced, including the chassis subassembly, still include: the device comprises a gear train assembly, a power assembly and an elastic assembly. The one end of train subassembly with power component hinged joint, the other end of train subassembly passes through elastic component set up in on the chassis subassembly, the power component drive train subassembly. During the process of forward and backward movement of the AGV, if the ground is uneven, the suspension structure can float along an arc line by taking the hinge shaft as an origin, so that the driving wheels move forwards. The backward direction and the up-down direction are floated, the position relation of the driving wheels relative to the middle two-dimensional code scanning port is changed along the X-axis direction, and the traveling precision of the AGV is adversely affected. The spring elasticity direction of the suspension structure is not fixed, the contact force structure of the driving wheel and the ground is complex, and the suspension structure is easy to slip under the conditions of low load and low ground roughness. When the floating driving wheel is floated, the position of the driving wheel changes back and forth on the horizontal plane, and the motion control precision is influenced. The spring force changes complicatedly, and is not beneficial to calculating and controlling the ground gripping force of the driving wheel.
