Problems solved by technology
[0003] Among the electronic parts on the mainboard, some of the larger parts are mainly hand plug-ins. However, manual configuration of these hand plug-ins is prone to errors. For example, the polarity of the parts of the hand plug-in should often be reversed or the parts are missing. , In addition, when the defective motherboard is sent for repair, during the transportation process, sometimes the parts of the motherboard will be touched by mistake and the parts will fall off. Therefore, it is necessary to check the configuration of the parts before maintenance to avoid misjudgment during maintenance.
At present, most manufacturers currently inspect motherboards manually, which is not only slow and time-consuming, but sometimes it is difficult to detect wrong component configurations during the inspection process, making it difficult to increase production capacity and product yield.

Embodiment Construction
[0029] figure 1 It is a block diagram of a system 1000 for automatically determining the correctness of parts according to an embodiment of the present invention. Please refer to figure 1 The system 1000 for automatically determining the correctness of parts provided by the present invention includes a storage unit 110, an image acquisition device 120, an identification module 130, a database creation module 140, and a graphical interface module 150. The identification module 130 is coupled to the storage unit 110 and the image acquisition device 120. The database creation module 140 is coupled to the storage unit 110 and the image acquisition device 120. The graphical interface module 150 is coupled to the database creation module 140 and the identification module 130. Through the operation of the above-mentioned components, the system 1000 for automatically judging the correctness of parts can detect multiple parts with larger volumes on the main board at one time to determi...

The invention discloses a method for automatically identifying part correctness, which comprises the following steps that a standard part database is established, wherein the standard part database records standard part videos, and position information and part attributes of the standard part videos; a complete video of a tested mainboard is shot; corresponding videos of parts to be tested are acquired from the complete video of the tested mainboard according to individual position information of the standard part videos; and the videos of the parts to be tested are analyzed by using individual part attributes of the standard part videos, so as to generate an identification result whether part configuration in the videos of the parts to be tested is correct. Therefore, the configuration correctness of multiple parts in the mainboard can be judged automatically, the product quality can be improved, and the judgment time can be shortened.
Description
Technical field [0001] The invention relates to a method for detecting parts, in particular to a method for automatically judging the correctness of parts. Background technique [0002] With the rapid advancement of electronic technology, various electronic products have become increasingly popular in our work and life, especially the most common electronic products such as information and home appliances. In order to allow these electronic products to produce special functions, almost all electronic products have a motherboard (Motherboard), which is mainly composed of many electronic components and circuit boards, and these electronic components are mounted on the circuit board and are connected to the circuit board. The internal circuits are electrically connected to each other. [0003] In the electronic parts of the motherboard, some of the larger parts are mainly hand-plugs. However, manual configuration of these hand-plugs is prone to errors. For example, the parts of the h...
