Automatic verification system and method for electric energy meter

Abstract

The invention provides an automatic verification system and method for an electric energy meter. The system comprises a PLC (Programmable Logic Controller), a delivery roller transport line controlled by the PLC and used for delivering turnover boxes out of a storage, a return roller transport line for returning the turnover boxes to the storage, a single-layer turnover box cache line for transporting the turnover boxes, a turnover box stacking cache line for caching the turnover boxes, an electric energy meter recheck belt line for transporting unqualified electric energy meters; a metering tray transport line for transporting a metering tray, a feeding robot and a discharging robot for moving electric energy meters or turnover boxes, and a turnover box monitoring sensor connected with the PLC and arranged on the single-layer turnover box cache line. By adopting the caching mode of combining a single-layer turnover box cache area with a multi-layer turnover box stacking area and intelligently transporting the turnover boxes via roller lines, the task executed by each robot at the same moment is balanced, the action path of a single robot is simplified, and the operating efficiency of the feeding and discharging robots is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electrical automation control and electric energy measurement, in particular to an electric energy meter automatic verification system and method. Background technique [0002] The electric energy meter automatic assembly line verification system is a new type of automatic instrument detection system, which can automatically complete a series of actions such as the discharge, transportation, verification, and sorting of the electric energy meter. Pallets are transported, and the electric energy meters delivered from the intelligent vertical warehouse system are packed in paper turnover boxes, so the electric energy meters are transferred from the turnover boxes to the measuring trays or sorted from the measuring trays to the turnover boxes. The feeding and unloading of the electric energy meter is the key link in the operation of the automatic verification line. The electric energy meter loading and unloa...

Problems solved by technology

[0003] The existing operation strategy of the robot for loading and unloading unit of the electric energy meter is to send all loading (unloading) tasks to the same robot, so that the same robot has to carry out the work of transferring the electric energy meter and grabbing the empty turnover box. However, this "self-sufficiency" strategy design restricts the efficiency of the loading and unloading unit, and it is difficult to ensure that the operation rhythm matches the entire system. In addition, the robot has complicated action steps, many command signals, and a set of cyclic actions involves multiple angles and multiple objects. , affecting the operating efficiency of the entire electric energy meter automatic verification assembly line
