The role of AGV forklifts in automotive production workshops

Introduction to the Four Major Processes in Automobile Manufacturing
In the automotive manufacturing industry, stamping, welding, painting, and final assembly are the four major processes
The main materials in the stamping workshop are steel coils and steel plates. The surrounding supporting equipment includes mold cutting lines, stamping machine molds, inspection tools, etc. The main materials in the welding and assembly workshop are stamping parts, as well as various standard parts such as screws and nuts. The surrounding equipment includes various fixtures, spot welding machines of various specifications, secondary welding machines, sub assembly welding wires, main and floor chain wires, etc. The main materials in the painting workshop are: white body, paint, PVC sealant, waterproof wax, etc. The peripheral equipment includes: electrophoresis line, baking oven, sealant coating line, and polishing line. The main materials in the final assembly workshop are: the main color body line (C section, T section, F section), and each sub assembly line (door line, dashboard). The peripheral equipment includes: each sub assembly line and the main floor chain line.

A complete automobile factory requires many branches to complete the production of a car. The land area often requires tens of thousands of square meters, so in many car factories, logistics and related labor costs are very high, requiring the transportation of materials from various process workshops.

The final assembly workshop is the one that involves the most detailed processes and materials in the entire automotive production process. The design of the line side warehouse in the final assembly workshop and the flow line design of logistics warehousing are the most effective ways to improve the efficiency of factory use and production.Line side warehouses are the intersection of production logistics and production assembly, so when it comes to factory logistics, we need to start with line side warehouses.

In terms of spatial layout, there are many types of parts and a large area occupation. The layout of each buffer area and packaging line is related to the length of the logistics route

In terms of personnel input, warehousing and distribution are the most human resource intensive. In warehousing, a large number of warehouse managers need to be deployed for warehouse management, including receiving, shelving, delisting, sorting, inventory, and accounting processing. In terms of delivery, it is necessary to invest a large number of delivery personnel to deliver materials, which can be divided into dedicated personnel, dedicated areas, and other methods.

How to improve the assembly efficiency of the final assembly workshop, increase the efficiency of factory area utilization, and at the same time reduce labor costs?

Learn about our AGV forklift, which can achieve seamless integration with factory WMS and ERP systems.The technological content of AGV itself enables it to operate safely and efficiently in the factory.Let's take a look at what technologies AGV has?

1 Navigation system

Compatible with SLAM environment navigation and reflector navigation, flexible combination, suitable for various production environments ；
The navigation system unit has multi-layer map switching navigation, which can satisfy the navigation of large areas and multi-floors;
Environmental data (various walls, columns, shelves, etc.) and reflective panel data are obtained by laser navigation sensors to build environmental maps, and environmental maps are matched with laser data during navigation to achieve real-time navigation and positioning 2 23D vision system:

Identify the tray hole position, dynamically adjust the fork ing direction, and automatically take the tray
Identify the hole position of the pallet, dynamically picking up the specified empty pallet according to the production demand
Identify obstacles and avoid them

3Warehouse visual identification system

1.Empty tray storage area and delivery cache area with camera identification system installed on top of the area;

2.Automatically identify the storage information in the area (empty/full) through AI algorithm

3.Automatic identification, automatic update of warehouse information, no need to manually scan code confirmation.

The following are photos of our company's AGV forklift used at the BYD factory in Zhengzhou, China.

It can achieve 24-hour uninterrupted work, handling equipment and materials up to 1.5 tons in the BYD factory.
