Circuit board assembly detection system

Abstract

The invention discloses a circuit board assembly detection system. The circuit board assembly detection system mainly comprises a conveying device as well as code spraying equipment, ICT test equipment, nixie tube plugging equipment, FCT test equipment, CCD scanning equipment and oil spraying equipment which are sequentially arranged along the conveying direction of the conveying device. According to the circuit board assembly detection system, the code spraying machine can perform automatic code spraying on circuit boards; the ICT test equipment can automatically perform ICT tests on the circuit boards; the nixie tube plugging equipment can automatically plug nixie tubes into the circuit boards, so that the speed and efficiency of the plugging of the nixie tubes can be improved; the FCT test equipment can automatically perform FCT tests on circuit boards to be detected, and therefore, test efficiency and test accuracy can be both improved; the CCD scanning equipment can perform automatic detection on the nixie tubes on the circuit boards; and the oil spraying equipment can perform automatic oil spraying processing on circuit boards which have been subjected to assembly detection, and the oil spraying equipment is connected with a baking box, and therefore, ink drying time can be shortened, and the production cycle of the circuit boards can be shortened.

Description

technical field [0001] The invention relates to the assembly and detection of microwave oven circuit boards, in particular to a circuit board assembly detection system. Background technique [0002] Nowadays, the assembly of microwave oven circuit boards in factories is mostly done manually, and generally requires 8 people to complete, including 1 person for manual repair welding, 1 person for ICT testing, 2 people for digital tube installation, 2 people for FCT testing, 2 people for cleaning oil, and board closing. One person stamping is not only labor-intensive, but also easily leads to quality problems. [0003] When processing circuit boards, it is often necessary to spray codes on the circuit boards to mark the production information such as the batch number of the circuit boards, so as to facilitate subsequent quality control and timely trace the batch number. Currently, the printing of circuit boards is done manually. In the traditional way, the coding speed is low, ...

At present, the normal test of the circuit board is carried out by a multimeter. During the test, each data parameter of the test target board is tested one by one through the multimeter and a power-on test target board, and then compared with the normal data parameters, so as to realize the normality of the test target board. Test, this test method needs to test parameters one by one during the test, so not only the test is time-consuming and laborious, but also the test efficiency is low, and the accuracy of the multimeter is not enough, the accuracy of the test is low, and the FCT test is a live operation, and employees contact When it comes to testing the target board, it is easy to cause safety accidents due to improper operation and electric shock

[0006] When producing circuit boards, sometimes it is necessary to insert digital tube plug-ins according to needs. At present, the installation of digital tubes on the circuit board is mostly manual operation. Manually inserting digital tubes is not only slow and inefficient, but also leads to missed insertion and improper insertion. situation, and in today's increasingly expensive labor costs, it also increases the production cost of enterprises

[0007] After the assembly and inspection of the circuit board is completed, a step of oil cleaning is required. A layer of ink is sprayed on the surface of the circuit board as a protective layer of the circuit board, which can prevent the physical disconnection of the conductor circuit and prevent the oil from being damaged due to dust and moisture. Insulation deterioration, corrosion and other effects caused by external environmental factors, the current production process is generally artificial spraying ink, but artificial spraying will cause uneven spraying, or spray ink everywhere, and the ink contains certain toxins, workers Long-term exposure will cause certain damage to the body
