Description

Technical Field

[0001] This utility model specifically relates to the field of spraying equipment technology, and more specifically to a PCB board solder resist spraying equipment with real-time visual detection function. Background Technology

[0002] In today's rapidly developing electronic information technology landscape, PCBs, as key components of electronic products, are directly affected by the sophistication of their manufacturing processes, which in turn impact the performance and quality of those products. Solder resist application, a crucial step in the PCB production process, plays an indispensable role in ensuring the electrical insulation of the circuit board, preventing short circuits, and improving circuit durability. As electronic products continue to advance towards miniaturization, high performance, and high integration, increasingly stringent high-precision requirements are being placed on the PCB solder resist application process.

[0003] Traditional PCB solder resist spraying equipment often employs a fixed mode based on preset parameters. In this mode, the spray gun follows a predetermined path and flow rate, making it difficult to respond accurately and in real-time to the individual differences of different PCBs. Firstly, different PCB models vary significantly in size, circuit layout, and copper thickness distribution. For example, some high-end electronic products have extremely dense circuits on their PCBs, with line spacing potentially reduced to the micrometer level. Simultaneously, to meet high power requirements, the copper thickness in some areas is significantly increased. Faced with such complex PCBs, traditional spraying equipment cannot flexibly adjust the spraying amount according to changes in circuit density, nor can it accurately control the solder resist thickness in areas with different copper thicknesses. This easily leads to overspray in densely packed areas causing circuit adhesion, while insufficient spraying in areas with thicker copper results in substandard insulation performance. On the other hand, during long-term spraying operations, the mechanical wear of the equipment itself, subtle changes in ink viscosity, and the influence of environmental factors such as temperature and humidity fluctuations can cause the actual spraying effect to gradually deviate from the preset standard. However, it is difficult to detect and correct this in time, which ultimately leads to a large number of products having quality defects, greatly reducing production efficiency and increasing production costs.
