Automatic tray state recognition method

Abstract

The invention provides an automatic tray state recognition method which is applied to a material counting machine and comprises the steps that S1, trays needing to be tested are placed in a material level area; S2, an image shooting module moves to the position above the material level area to automatically collect images; S3, a collection processing module calculates and analyzes the images acquired by the image acquisition module, if a complete identification graph is displayed in the acquired images, it is judged that the material trays are not placed in the material level area with the complete identification graph, and if the complete identification graph is not displayed in the acquired images, it is determined that the material trays are placed in the material level area; S4, an output marking module prints information labels of the trays corresponding to the material level area as required according to analysis results obtained by the collection processing module. According tothe method, whether the trays are placed in the corresponding material level areas on the tray stations of a counting machine or not can be automatically recognized, the overall counting detection efficiency is improved, and time and cost are saved.

Description

technical field [0001] The invention relates to the technical field of SMT, in particular to a method for automatically identifying the state of a tray. Background technique [0002] Electronic processors need to maintain enough memory for various components required for manufacturing, but piles of resistors or transistors and many other small parts are not only difficult to store, but also a big problem for quantity control. Users need to be able to accurately Only by controlling the current inventory quantity can we effectively manage storage conditions and costs.

[0002] Electronic processors need to maintain enough memory for various components required for manufacturing, but piles of resistors or transistors and many other small parts are not only difficult to store, but also a big problem for quantity control. Users need to be able to accurately Only by controlling the current inventory quantity can we effectively manage storage conditions and costs

[0003] But this situation has changed with the development of SMT (Surface Mount Technology, the abbreviation of Surface Mount Technology). In the automatic production line, the tray is usually used to hold the components, and the operator will regularly paste a large number of components The method is configured on the winding SMT tape, and then the SMT tape is rolled into a reel and then the flow operation is carried out. However, in order to always know the number and type of components in each reel, it is necessary to use a spotting machine to adjust the reel. Carry out detection and paste a label with material tray information on its surface, and scan the label to know the condition of the material tray. At present, the spotting machine can only output the labels of all material level areas at one time during the entire test process, and cannot automatically identify Whether there is a tray on a certain material level area, and then the operator takes out the label and pastes the printed label according to the position of the material level area where the tray is located. This process is inefficient, time-consuming and costly
