Abstract

The invention provides a weight detecting method and system. It is applied in a product processing procedures, e.g., the manufacturing procedure, testing, quality control, and package. Via a weighting mechanism in the process of transferring the object, it enables the user to detect the weight of an object. Further, an analysis mechanism is employed to analyze and compare the error of the weighting result with the specification such as weight of material required for at least the object pre-stored in a database. Furthermore, it determines possible material configured erroneously that causes the error value. By means of this way, the user can in advance be aware of the possible reason that causes the weighting error of the object. Eventually, it increases the efficiency in detecting objects.

Description

200521411 • V. Description of the invention (1) ^ [Technical Field to which the Invention belongs] A method and system for detecting the weight of a subject, and more specifically, a method and system for detecting whether a material is in shortage by analyzing the weight error of the object. [Previous technology] For a company, factory or enterprise that uses manufacturing as a business item, the life cycle of a product (1 i f e c y c 1 e) can be described as including design, testing, manufacturing, sales and even after-sales service. With today's products, especially electronic information products, such as notebook computers, which constitute a complete product, the number of components required may be in the hundreds or hundreds, plus the operation of its system needs to be tested < 11 to operation Convenience, system stability, equipment scalability, and heat conduction effects. Therefore, from the process of product design to the hands of consumers, the process related to the product includes any relevant processing procedures, processing guidelines and related approvals, use rights, safety, working standards and methods, work processes, institutional relations, and engineering testing. Wait for all procedures to process. Taking the manufacturing and assembly of a notebook computer as an example, in many manufacturing and assembly processes, product manufacturing can be generally divided into printed circuit board plug-ins and system assembly. The printed circuit board plug-in process can be divided into: surface mount plug-in (SMT), automatic plug-in (A / I, Auto Insertion), manual plug-in 0, test and burn-in test (Bu r η-I η), etc. The system assembly process can be divided into housing assembly, aging, testing and packaging. The assembly of a notebook computer is carried out as a whole machine like a calculator. The operation complexity is higher than that of a desktop computer. Packaging operations are mostly automated. Compared to the traditional manual or manufacturing process,

17654 Yingyeda.ptd Page 6 200521411 V. Description of the Invention (2) The mechanism of automation can indeed minimize the error rate of manufacturing or assembly. However, it does not mean that there will be absolutely no errors. This is why manufacturers with a high degree of automation must still have testing and quality control. According to my knowledge, most of the quality control inspection process is performed manually. Maybe when the components are exposed, it can be inspected visually by the quality control inspector. Regardless of the accuracy of the visual inspection, once there is Products that have not been detected with errors have been packaged, and they cannot be detected manually afterwards.
