Description

[0001] The present invention relates to a battery automatic charger for a contactless unmanned vehicle,

The present invention relates to a battery automatic charging apparatus for a contactless automatic guided vehicle in which charging is performed by sensing the position of an automatic guided vehicle moved to a charging position, more specifically, , It is possible to display the operation status of the device including the charging status on the screen, to detect the completion of charging voltage, to automatically terminate the charging, and to provide the operation panel so that the user can select the manual or automatic charging mode. And more particularly, to a battery automatic charging apparatus for a contactless automatic guided vehicle capable of enhancing reliability of the apparatus.

Generally, unmanned transportation vehicles are widely used in automation systems such as logistics systems and automatic production systems in order to reduce labor costs and improve work efficiency. have.

That is, the unmanned vehicle is an automatic guided vehicle (AGV), which is a trackless vehicle that carries the cargo to the designated place manually or automatically on the vehicle body, Automatic Guided Tractor, which is a trackless vehicle that automatically trains a freight to or from a specified place and automatically runs to the indicated place, and a mast that operates up and down the fork for loading freight, (Automatic guided fork lift truck), which automatically loads and automatically unloads to the indicated location.

Such unmanned transportation vehicles are widely used in various industrial fields such as semiconductor manufacturing industries, and are responsible for transporting logistics by the instruction of the main computer. Since the battery is used as the power source, the electric power charged in the battery is consumed to some extent A charging device is provided to allow the unmanned transportation vehicle to automatically move to a predetermined place to recharge the battery.

In the unmanned conveying vehicle charging system according to the related art, when the idle power of the built-in battery falls to a set value for charging, the unmanned conveying vehicle traveling according to the control of the main computer controlling the operation of the unmanned conveying vehicle, So that charging is performed.

That is, in the past, when the unmanned transportation vehicle is operated by the internal battery and needs to be charged using the battery for a certain period of time, a battery down signal is generated to inform the main computer, When the unmanned conveyance vehicle requiring recharging reaches the charging station, the operator manually removes the discharged battery mounted on the unmanned conveying vehicle and then replaces the previously charged rechargeable battery, Was used.

However, since the battery exchange method depending on manual operation according to the prior art requires manpower for battery replacement, it has been difficult to standardize the operation and it is difficult to economically operate due to labor costs.

In order to overcome such disadvantages, the automatic charging apparatus of an automatic guided vehicle or a conveyance car is disclosed in Korean Patent Publication No. 1994-0000389 (Application No. 1991-0010006, No. 91.6.17) and Japanese Utility Model Publication No. 61-104739 And the like are disclosed. The above-mentioned prior art is characterized in that it is composed of a charging device for charging projected from a floor and a charging device for charging resiliently protruding from the lower surface of the automatic guided vehicle so as to charge a battery mounted on the automatic guided vehicle The charging and discharging device is intermittently connected to the charging device for charging the charging device to charge the battery mounted on the automatic guided vehicle to maintain the fully charged state at all times whenever the automatic guided vehicle travels on a predetermined trajectory.

Another conventional technology is an automatic unmanned vehicle automatic charging device disclosed in Korean Patent Laid-Open Publication No. 1995-0034967 (Dec. 28, 1995), in which a fixed position magnetic sensor is installed on an unmanned conveyance vehicle traveling in a predetermined orbit, Placing the magnetic magnet so that the unmanned conveyance vehicle reaches the charging position by the magnetic field of the stationary magnetic magnet and is located slightly below the floor of the floor connected to the power supply and installed on the floor , Positive (+) and negative (-) electrode terminals can be operated seesaw to increase the contact force with the electrode terminals of the charging and discharging device, The charging and discharging device of the present invention is capable of charging and discharging the battery by charging and discharging the battery by connecting the plus and minus electrode terminals thereof to the charging / .

However, most of the automatic unmanned automatic vehicle recharging devices according to the related art have a charging terminal protruding outwardly for power supply. Such a protruding electrode can be applied to each electrode during operation or charging operation of the unmanned vehicle, In addition, there is a problem in that the spark is generated in the charging process to cause an overload in the charging device, and the risk of damage or breakage of the device due to the spark occurs. There was a problem.

In addition, since the electrodes themselves are extremely small, it is difficult to electrically contact each other unless the automatic guided vehicle is stopped at an accurate charging position. In addition, since the setting time takes a long time, .

In addition, most of the conventional automatic unmanned vehicle automatic recharging apparatuses are not provided with information on the state of charge or the result of charging, Because it can not be changed, it can be charged only for unmanned vehicles using batteries with the same rated specifications. Therefore, it is not possible to use universal use for several unmanned vehicles equipped with different batteries having different specifications. There has been a problem in that a charging device that meets specifications has to be provided.

In addition, since the conventional automatic unmanned vehicle automatic charging apparatus does not provide an indicator lamp indicating charging or completion of charging, or is provided too small, there is a disadvantage that it is difficult for a remote worker to visually recognize at a work site.
