Description

AGV floor truck is selected in relay with sweep a yard camera

Technical Field

The invention relates to the field of mechanical equipment, in particular to a storage sorting AGV (automatic guided vehicle) carrying trolley structure with a code scanning camera.

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. And in the prior art, the position precision and the angle precision between the bodies of the AGV sweeping wharf and the driving wheels are insufficient, so that the running precision and the parking precision of the AGV trolley are influenced when the movement is controlled.

Disclosure of Invention

The invention aims to solve the technical problem of overcoming the problems in the prior art and provides a relay picking AGV carrying trolley with a code scanning camera.

In order to solve the above problems, the technical solution of the present invention is as follows:

AGV floor truck is selected in relay with sweep a yard camera, including the dolly body, dolly body lower part is provided with the camera mounting groove, is provided with the camera mounting panel in the mounting groove, sweeps a yard camera and passes through camera mounting panel fixed mounting in the mounting groove

The mounting plate is vertically inserted into the mounting groove.

The mounting plate is of a portal structure.

And mounting bolts are arranged on two legs of the mounting plate portal frame.

The mounting plate head is provided with a mounting bolt.

Has the advantages that: in order to ensure that the mounting plate of the wharf sweeping machine is mounted on the position precision of the frame bottom plate 401: the mounting plate of the wharf sweeping head is positioned by 2 pins and connected with 4 bolts and the frame bottom plate 401. The pin positioning connection can guarantee to sweep the position precision between pier mounting panel and the automobile body, and the pin has the effect of anti-shear force simultaneously, and four bolts only play the effect of axial locking, can prevent like this that AGV from long-time running under abominable operating mode, because the vibration leads to sweeping the not hard up condition of pier mounting panel. In addition, the mounting plate of the wharf sweeping head is formed by cutting a plate through laser, the processing precision is high, the mounting precision and the strength of the wharf sweeping head are guaranteed, and the two-dimensional code position and the angle information on the ground can be stably and accurately read.

The frame bottom plate 401 is formed by cutting through a laser cutting machine, and the linear guide rod mounting threaded hole, the pin hole and the wharf sweeping mounting threaded hole bottom hole are formed by cutting through laser, so that the precision of the plurality of hole sites is high, and the high precision of the positions among the wharf sweeping, the driving wheel and the vehicle body assembly can be ensured.

Drawings

The invention is described in detail below with reference to the drawings and the detailed description;

fig. 1 is a schematic view of a bottom structure of a relay picking AGV transfer trolley according to the present invention.

Fig. 2 is an exploded view of the camera mounting structure according to the present invention.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.

Referring to fig. 1, the laser wharf sweeping assembly 406 comprising the driving wheels 106, the universal wheels 201 and the universal wheels is shown in fig. 2.

Referring to fig. 2, the laser dock broom assembly 406 comprises a laser dock broom head 4061, a dock broom mounting plate 4062, dock broom mounting screws 4063, alignment pins 4065, and dock broom mounting plate mounting screws 4064. The mounting plate 4062 of the pier is formed by laser cutting, and the overall precision and the hole site precision are high.

With continued reference to figures 1 and 2, the dock broom mounting screws 4063 pass through the dock broom mounting plate 4062 holes to lock the laser dock broom 4061, the locating pins 4065 locate the laser dock broom assembly 406 on the chassis base 401, and then the dock broom mounting plate mounting screws 4064 lock the laser dock broom assembly, and the accuracy of the dock broom mounting position and the assembly strength are improved by pin locating and bolt locking. Four universal wheels 201 are arranged at four corners, and are ensured to be on a horizontal plane through a processing technology and an assembling technology, and the stability of the whole vehicle is ensured by running the four universal wheels together. The two driving wheels 106 can float up and down under the guidance of the linear guide rod, so that the two driving wheels are always in contact with the ground and have a certain positive pressure, and the driving wheels are fixed in position in the horizontal direction relative to the laser wharf 406, so that the running speed of the wheels driven by the differential control quantity is high, and the whole running precision is high.
