Description

Technical Field

[0001] The utility model relates to a circuit board cleaning technology, in particular to a circuit board circulation cleaning device. Background Art

[0002] Circuit boards can be called printed circuit boards or printed circuit boards. Excellent flexible printed circuit boards have the characteristics of high wiring density, light weight, thin thickness, good bending properties, and hard-flex boards, which have given rise to a new product called hard-flex boards. Therefore, hard-flex boards are flexible circuit boards and rigid circuit boards. After lamination and other processes, they are combined according to relevant process requirements to form a circuit board with FPC characteristics and PCB characteristics.

[0003] Since electroplating can enhance the corrosion resistance of circuit boards (plating metals are mostly corrosion-resistant metals), increase hardness, prevent wear, improve conductivity, smoothness, heat resistance and surface beauty, there will be certain impurities on the surface after electroplating, which need to be cleaned. However, most of the cleaning devices currently used have limitations in cleaning, and cannot clean circuit boards of different sizes. It is necessary to adjust the corresponding limit distance to achieve cleaning of circuit boards of different sizes. In addition, it is difficult to ensure the appropriate distance during the adjustment process, which is not convenient for quick operation. Utility Model Content

A first conveying member 11 is provided at one end of the base 1, and a second conveying member 12 is provided at the other end. The first conveying member 11 is used to convey the uncleaned circuit board to the cleaning area 6, and the second conveying member 12 is used to transfer the cleaned circuit board from the cleaning area 6. The spray head 7 sprays the cleaning liquid, the first cleaning roller 8 and the second cleaning roller 9 are used to clean the bottom surface of the circuit board, and the dryer 10 is used to dry the circuit board.

[0026] The conveyor belt 2 is arranged in the installation area 5, and the conveyor belt 2 is symmetrically arranged. A rotating disk 13 is arranged on the base 1, and a motor is arranged at the lower end of the rotating disk 13. The rotating disk 13 is arranged in the middle of the conveyor belt 2 and distributed at both ends. The conveyor belt 2 is arranged on both sides of the cleaning area 6.

[0027] The support assembly 3 is installed on the conveyor belt 2, and the support assembly 3 is provided at multiple locations. The support assembly 3 is composed of a support member 14 carrying the circuit board and a mounting member 15. The support member 14 is installed on the conveyor belt 2 through the mounting member 15. The first conveying member 11 conveys the circuit board to the support member 14. The circuit board is carried and squeezed by the symmetrically arranged support members 14 and transferred to the cleaning area 6 along the conveyor belt 2.

[0028] The mounting member 15 is composed of a hexagonal portion 16 and a rod body 17, and the rod body 17 is mounted on the conveyor belt 2. The support member 14 is composed of a mounting section 18, a vertical section 19, a first elastic section 20 and a second elastic section 21. The mounting section 18 is connected to the vertical section 19 and is kept vertically arranged. The mounting section 18 is provided with a mounting hole that matches the rod body 17, and the rod body 17 is provided with a spring 22, one end of the spring 22 contacts the conveyor belt 2, and the other end contacts the mounting section 18.
