Problems solved by technology

However, the disadvantage of this technical solution is that the AVG needs to leave the production line to charge at the charging station, and then return to the left station on the production line to continue working after charging, which not only requires independent charging time to re

Example Embodiment

[0037] Example 1: figure 1 Shown is a flowchart of the present invention. In this embodiment, there are 21 sites and 4 AGVs. The basic steps are:

[0038] S101: Set a rectangular ground navigation magnetic strip around the automobile engine powertrain assembly production line as the closed running track of the AGV;

[0039] S102: Divide the rectangular ground navigation magnetic strip into 21 stations numbered 0-20 according to the characteristics of the process. The starting station 0 is used as the charging station and the engine powertrain hoisting station. The 4 AGVs are arranged in the rectangular ground navigation magnet. On track

[0040] S103: The AGV automatic charging device is installed at station 0, and when the AGV enters station 0, the loaded battery pack is automatically charged;

[0041] S104: Start of charging at station 0;

[0042] S105: The lifting of the engine powertrain begins;

[0043] S106: Judge whether the lifting of the engine powertrain is completed, go to S...

Example Embodiment

[0049] Example 2: Such as figure 2 Shown is a device for improving the endurance of the automatic navigation car, and the automatic charging device is installed at station 0. The controller adopts a single-chip microcomputer.

[0050] There are 4 AGVs on the production line; the production line is installed with rectangular ground navigation magnetic strips and divided into 21 stations (0-20); the four AGVs are automatically walking along the ground rectangular navigation magnetic strips, automatically stopping, and are on the 0th The stations are charged sequentially.

[0051] The AGV enters the No. 0 station for charging. At the same time, the operator hangs the engine power assembly through the electric lifting hoist and drops it onto the fixture tray on the AGV trolley.

[0052] When the AGV is not in the charging state (that is, under normal working conditions), the direction of current flowing on the sampling resistor RC is A to B, that is, the voltage is A positive and B neg...

Abstract

The invention discloses a method and a device for improving cruising ability of an automatic navigation trolley. By control on working modes of an AGV (automatic guided vehicle) and reasonable arrangement of stops, and production requirements are met, working reliability and working efficiency of the AGV are improved. The device comprises a rectangular ground navigation magnetic strip used for determining traveling routes of the AGV, an automatic charging device used for marking off a plurality of stops according to a serial number starting from 0 on the rectangular ground navigation magnetic strip and mounting the AGV on the number 0 stop, a controller used for controlling the working modes of the AGV, a charging detection circuit used for detecting charging states of the AGV, a forced starting key used for forced starting of the AGV, and a hoisting completion key used for informing the controller when hoisting of an engine power assembly is completed, and the controller is connected with the charging detection circuit, the forced starting key and the hoisting completion key respectively.

Description

technical field [0001] The invention relates to an automatic navigation car, in particular to a method and a device for improving the insufficient battery life of the automatic navigation car on an automobile production line. Background technique [0002] At present, domestic automobile OEMs generally adopt internationally advanced automatic navigation vehicles (AGV). However, AGV often has difficulty in lifting the lift in the engine assembly area. Sometimes it suddenly stops working during the lifting process, and the buttons do not work. It can only be started in the manual state after shutdown and restart. At this time, the AGV is not moving, only one lift motor is working, and the load is relatively small to barely lift. If there are too many restarts, it will be paralyzed. The fault indication is that the rudder angle is out of deviation. This kind of fault seriously affects production. efficiency. After in-depth analysis, the root cause of the above failure is the i...
