Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, and more specifically, to a wireless headset PCBA board brush mechanism. Background Art

[0002] The PCBA board of wireless earphones is the provider of line connection. Since it is made by electronic printing technology, it is called a "printed" circuit board. During the production process, the circuit board on which components are mounted often needs to be cleaned of tin beads, ash and tin slag. However, the existing method of brushing the board is to manually use an electrostatic brush to brush the board. After the brushing is completed, the PCBA board is tapped on the table. The number, range and strength of the brushing action are determined by the staff independently, and it is difficult to ensure the consistency of the operation. The tapping method can easily damage the components on the PCBA board, and the work efficiency is extremely low. Repeated PCBA board tapping will cause the electrostatic leather that protects the table to curl up, resulting in the need for replacement and other problems.

[0003] After searching, a Chinese patent with announcement number CN209363094U discloses a PCBA board brushing mechanism. This structure drives the cleaning roller to move horizontally to automatically brush the PCBA board, thereby realizing the function of cleaning the tin beads or tin slag on the PCBA board. This can improve work efficiency and avoid damage to components on the PCBA board due to problems such as force caused by manual brushing.

[0004] However, in actual use, since the structure needs to place the PCBA board on the surface of the workbench and use the cleaning roller to move horizontally to clean the PCBA board, and since the PCBA boards are of different shapes and sizes, when the cleaning roller encounters a smaller PCBA board during the rolling process, it is easy to throw it away due to excessive speed, and if the speed is too slow, the cleaning efficiency is reduced, so the adaptability is low during use.
