Description

TECHNICAL FIELD

[0001] The utility model relates to numerical control machine tool technical field, concretely related to a battery box with display module. BACKGROUND

[0002] In modern numerical control systems and servo drive systems, in order to ensure the data integrity and continuity of equipment after power failure, often rely on external battery box to maintain the saving of key parameters and position data, especially in the encoder position data of servo motor. When the equipment is powered off, the battery box will provide necessary power supply, ensure that these data can not be lost after power recovery, thereby reducing the debugging and resetting time. However, the traditional external battery box usually does not have real-time display function, so it cannot timely alarm when the battery voltage or current is abnormal.

[0003] Due to the lack of real-time monitoring and feedback mechanism, the operator often can only find that the battery has been depleted or in abnormal state after data loss, or when the equipment fails. This situation not only leads to data loss, but also may cause the equipment to stop for a long time, increase the debugging time and maintenance cost. If the battery has a problem during equipment operation, especially in high-precision and high-demand numerical control machining process, the downtime and equipment recovery process will become more complex, which seriously affects the production efficiency.

[0004] In addition, due to the lack of battery life management and alarm function in the external battery box, it is difficult for the equipment user to estimate the replacement cycle of the battery. With the passage of time, the gradual consumption of battery power may not attract enough attention until the equipment has a serious problem. This not only affects the smooth operation of the production line, but also increases the complexity and cost of equipment maintenance.
