Disk loading mechanism and control method of precious metal inspection machine

Abstract

The invention relates to a tray charging mechanism of a noble metal inspection machine. The tray charging mechanism comprises two slide rails, a control module, a motor, a lead screw, a feed sensor and a micro sensor, wherein the two slide rails are arranged symmetrically, a supporting plate is connected to the two slide rails in a sliding mode, the supporting plate is fixedly connected with the lead screw, the lead screw is in transmission connection with the motor, at least two waste coin trays are arranged on the supporting plate, a plurality of division plates are uniformly arranged on the waste coin trays in the width direction and divide the waste coin trays into a plurality of columns of coin receiving parts with the same size, the waste coin trays are connected with a coin detection device of the noble metal inspection machine by a coin conveying belt, the feed sensor is arranged at the coin outlet of the coin conveying belt, the feed sensor is used for acquiring the number of coins conveyed by the coin conveying belt in real time and transmitting the number to the control module, the micro sensor is used for acquiring micro signals generated by the waste coin trays and transiting the micro signals to the control module, and the control module controls operation of the motor and the coin conveying belt. The tray charging mechanism has the advantages of simple structure, small floor space, convenience in maintenance and short time consumption, and significantly improves the working efficiency.

Description

technical field [0001] The invention relates to a disk loading mechanism of a precious metal inspection machine and a control method thereof, belonging to the technical field of coin inspection equipment. Background technique [0002] According to the applicant's understanding, coin production technology is constantly developing, and the automation and efficiency of finished coin manufacturing, printing and packaging processes are also improving. Qualified quality has established strict criteria for judging. However, waste and unqualified products are inevitable in the coin production process. For a long period of time, the factory inspection of coins is carried out manually, which requires a large investment, high labor intensity, and unstable inspection quality. . At present, the banknote printing and minting industry is vigorously developing the automation technology of inspection and sealing, and the equipment using machine vision is also constantly being updated.

AI Technical Summary

Problems solved by technology

[0004] The existing coin loading mechanism is usually provided with a number of trays on the belt conveyor, and each tray has multiple columns of coin storage parts, and the belt on the belt conveyor drives the trays to move in one direction. After a tray is filled with a row of coins, it moves to The next column of the tray continues to be loaded until one tray is full and then moves to the next tray, and the process is carried out sequentially, and the tray is loaded in a circular manner. In this way, the interval between the first column and the last column is longer, which takes a long time and improves efficiency. Low, it will affect the quality of the tray, especially this kind of tray mechanism is large in size, occupies a large area, has a complicated structure, and is not easy to maintain
