Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCBA board processing, and in particular to a self-cleaning assembly and gluing device for PCBA boards. Background Technology
[0002] During circuit board manufacturing, adhesive needs to be applied to ensure the circuit board's waterproof and moisture-proof performance and to increase the connection stability between electrical components. Before applying adhesive, dust inevitably adheres to the circuit board surface. Existing circuit board adhesive application equipment lacks the function of cleaning the circuit board. During adhesive application, dust on the circuit board will affect the adhesive application effect. Even if the circuit board is cleaned by a cleaning device, dust can easily adhere to the circuit board again during the transfer to the circuit board adhesive application equipment, which will also affect the adhesive application effect.
[0003] The prior art patent application with publication number CN219478222U uses a plasma spray gun to clean PCB boards. The cleaning time is short, and the PCB board surface is dry after cleaning, eliminating the need for air drying. Furthermore, a dust collection component adsorbs the cleaned impurities, preventing them from floating in the air and re-adhering to the PCB board, thus improving the cleaning efficiency. However, current devices use a plasma cleaning machine as an auxiliary operation when cleaning the circuit board before applying adhesive. The plasma machine in the current device cleans the circuit board in an exposed manner, which makes it easy for external impurities to adhere to the surface of the circuit board.
[0004] Therefore, it is necessary to provide a self-cleaning assembly adhesive application device for PCBA boards to solve the above-mentioned technical problems. Utility Model Content
