Description

Technical Field

[0002] Fully automatic solder paste printers utilize mechanical positioning and optical alignment systems to automatically align the stencil and PCB pads, evenly applying pre-prepared solder paste to the pads on the circuit board. Solder paste is a viscous substance containing metal particles (typically an alloy of tin and lead) that is used to connect components and conductive traces on circuit boards. Fully automatic solder paste printers are widely used in electronics manufacturing, including smartphones, wearable devices, smart homes, networking equipment, automotive electronics, and medical devices.

[0003] The existing fully automatic solder paste printer still has the problem of coordinate offset when in use. When the coordinate setting of the printer is inaccurate, the solder paste cannot be accurately printed to the expected position. Therefore, the fully automatic solder paste printer relies on traditional positioning methods, such as mechanical positioning or simple sensor positioning. Its accuracy may be affected by many factors, such as equipment wear, environmental factors, etc., which in turn leads to coordinate offset and affects printing accuracy. For this reason, an AI vision fully automatic solder paste printer is proposed. Utility Model Content
