Description

Technical Field

[0001] This utility model belongs to the field of circuit board potting technology, specifically relating to a circuit board encapsulation potting machine. Background Technology

[0002] In the manufacturing process of electronic devices, circuit boards, as an important carrier of electronic components, are crucial in terms of performance and stability. The glue dispensing machine covers the surface of the circuit board with a layer of glue to form a sealing layer, which effectively prevents moisture, dust and other external substances from corroding electronic components and improves the circuit board's moisture-proof and dust-proof capabilities.

[0003] However, existing PCB dispensing machines still have some problems in practical use. For example, a PCB dispensing machine with patent publication number CN218282418U, although it has certain dispensing functions, relies on springs to clamp and fix the PCB. This method is not conducive to flexible adjustment according to different PCB sizes, which greatly reduces the equipment's versatility. In actual production, PCBs come in various sizes and specifications, and the fixed clamping method is difficult to meet production needs, increasing production costs and difficulty.
