Description

Technical Field

[0001] The utility model belongs to the technical field of flexible circuit board production, in particular to a clean water spray cleaning device for flexible circuit boards. Background Art

[0002] Flexible circuit boards need to be cleaned during manufacturing, and cleaning is done by soaking them in alkaline detergent or clean water. This not only removes dust on the surface but also facilitates the treatment of the oxide layer on the surface during subsequent scrubbing. Flexible circuit boards need to be cleaned using a cleaning device. The cleaning device is equipped with an immersion tank filled with alkaline detergent or clean water, and the flexible circuit boards are placed in the immersion tank for immersion.

[0003] A Chinese patent application (or patent) with publication number CN212367641U discloses a flexible circuit board cleaning device, comprising a device body, a top cover movably connected to the top of the device body, a sealing gasket fixedly connected to the bottom of the top cover, an alkaline cleaning agent disposed within the device body, an electrostatic ring fixedly connected to the outer wall of the device body, a first chute defined at the bottom of the device body, a first motor fixedly connected to the inside of the device body, the output shaft of the first motor fixedly connected to a threaded rod via a coupling, a second chute defined within the device body, and a support rod movably connected to the outer wall of the threaded rod. This flexible circuit board cleaning device facilitates automatic cleaning, solves the problem of inconvenient cleaning of flexible circuit boards, meets user needs, eliminates manual cleaning, improves work efficiency, reduces workload, and enhances work quality.

[0004] The aforementioned flexible circuit board cleaning device contains an alkaline detergent, which is used to soak the flexible circuit board. Dirt removed from the surface of the flexible circuit board after soaking is retained in the alkaline detergent solution, mostly in a floating state. Consequently, subsequent cleaning of the flexible circuit board is incomplete. Furthermore, to reduce production costs, the alkaline detergent within the device must be recycled. However, after cleaning the flexible circuit board, this alkaline detergent contains a significant amount of dirt, which remains in the solution, reducing the number of times the alkaline detergent solution can be reused and increasing production costs. To address this issue, we provide a water spray cleaning device for flexible circuit boards to address the aforementioned issues. Utility Model Content
