Description

Technical Field

[0001] The utility model relates to the technical field of SMT glue dispensing, and more specifically to an SMT glue dispensing device with a cleaning function. Background Art

[0002] SMT, the full name of Surface Mounted Technology, is the most popular welding technology and extremely stable and mature process in the electronic assembly industry.

[0003] Glue dispensing in SMT (surface mount technology) can fix components: glue dispensing is to drip glue to a fixed position on the PCB. Its main function is to fix components to the PCB board to avoid displacement or falling off during subsequent processing or use. Especially in the mixed assembly process where SMT patches and THT (through-hole mounting of lead components) coexist, the glue dispensing process is particularly important for the curing of components; improve the performance of circuit boards: glue dispensing can enhance the dustproof, shockproof and waterproof capabilities of electronic products, making them more durable. Through glue dispensing, electronic products are not prone to corrosion, moisture or short circuits due to water ingress; prevent metal corrosion: when the circuit board module is potted, glue dispensing can effectively avoid metal corrosion, thereby improving the performance of the circuit board; improve insulation and stability: after glue dispensing, the insulation of the circuit board will be greatly improved, not only stable operation and good performance, but also help to improve the overall performance and user experience of electronic products.

[0004] Although dispensing glue in SMT (surface assembly technology) has many beneficial effects, the glue will leak onto the workbench during the dispensing process, making it inconvenient to clean the workbench surface. The long-term accumulation process will affect the subsequent processing efficiency of the workbench. Utility Model Content
