[0003] During the above-mentioned loading process, the operator often misread the information listed on the station number table and placed the material tray in the wrong position, so that the SMD circuit board was printed with the wrong material. Moreover, it was often the end of the loading process and the test It was discovered that the SMD circuit board had been printed with the wrong material at the station,

Embodiment Construction
[0045] Please refer to FIG. 2 , which is a block diagram of the system structure of the feeding control system of the present invention. As shown in the figure, the feeding control system of the present invention includes a scanning device 30, a database server 31, a query unit 32, a microprocessor unit 33, a refueling calculation unit 34, a display unit 35, a refueling list printing module 36, and a storage unit 40 and the I / O control unit 41, wherein each line position (L1', L2') of the SMD operation station 1' needs to be connected to the feeding control system respectively, and each machine platform (MV1', MV2', MV5' ) are respectively connected to the storage unit 40 and the I / O control unit 41 (that is, at the dotted line box), wherein, in order to simplify the drawings and descriptions, the system architecture here only shows the SMD operation station 1' part of the machines.
[0046] First, the material number of each tray 2 needs to be coded in advance, and the coded...

Abstract
Charging control system and its method applies to charging control in SMD work station, the corresponding bar code is pasted on the material plate in advance, the bar code has information of materialnumber, quantity of material supply and the numbers of bar code, and the bar code corresponds to SMD station number, it stores the bar code and SMD station number table into data bank, it sets up station number corresponding table with the material plate putting sign of charging control system in every station, it numbers the material plate putting sign corresponding to station, and it stores thestation number corresponding table into store unit. At first it scans the bar code of material plate; when the material plate is set in the station, it generates the putting sign.
Description
technical field [0001] The present invention relates to a technology for feeding trays in SMD operation stations, in particular to a feeding control system and method to remind operators of the correct station for placing trays, and to feed trays in the stations Before the material is used up, the operator can be notified in advance to change the material. Background technique [0002] Generally, in the process of loading materials at the surface mount device (SurfaceMountingDevice, hereinafter referred to as SMD) operating station, the operator performs the loading according to the number of stations made by, for example, Excel1 software, such as figure 1 As shown, it is an SMD operation station 1. The operation station 1 includes a plurality of operation lines (L1, L2, L3, ..., Ln), and each line position is composed of several machines (MV1, MV2, MV5, ... etc.), where each machine has multiple stations (not shown), and each station has a number, such as 001, 002, 003, 00...
