Precious metal inspection machine

Abstract

The invention relates to a precious metal inspection machine which comprises a coin conveying channel, an image processing module and a master control module. A coin conveying assembly, a coin clamping mechanism, a coin detection mechanism, a discharging assembly and a waste coin panning mechanism are sequentially arranged on the coin conveying channel. The coin clamping mechanism is mainly composed of a coin input device, a coin supporting device and a rotating device. The rotating device comprises a rotating motor and a rotating disc installed on the rotating motor. A set of clamping holders for horizontally clamping coins are uniformly distributed on the rotating disc in the circumferential direction. The waste coin panning mechanism comprises two sliding rails, a lead screw, a lead screw motor, a feeding sensor and a micro motion sensor. The two sliding rails are symmetrically arranged, a supporting plate is connected to the two sliding rails in a sliding mode and fixedly connected with the lead screw, the lead screw is driven by the lead screw motor, at least two waste coin discs are arranged on the supporting plate, a plurality of partition plates are uniformly arranged on the waste coin discs in the width direction of the waste coin discs, the waste coin discs are partitioned into a plurality of columns of identical coin storage portions. The precious metal inspection machine has the advantages of being compact in overall structure and small in occupied area.

Description

technical field [0001] The invention relates to a precious metal inspection machine, which belongs 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. [0003] After retrieval, it was found that the Chinese ...

Problems solved by technology

In the process of coin conveying, two or more coins often stick together, and the above-mentioned patent is to complete the pattern collection of the entire coin through the line-scan camera mosaic. During the mosaic process, it is easy to have defects such as graphic misalignment and black shadows. Affect the inspection results

[0004] The tray loading device of the existing coin checking machine is usually provided with several trays on the belt conveyor, each tray has multiple rows of coin storage parts, the trays are driven by the belt on the belt conveyor to move in one direction, and a tray is filled with a row of coins Then move to the next row of the tray and continue loading until one tray is full, then move to the next tray, and proceed sequentially, using a cyclic method for loading, this way the interval between the first row and the last row is longer, time-consuming Long, low efficiency, will affect the quality of the plate, especially this kind of mechanism is large in size, large in floor space, complex in structure, and difficult to maintain
