Description

Technical Field

[0001] The utility model provides a cleaning device, which belongs to the technical field of circuit board production equipment, and particularly relates to a water cleaning device for a circuit board electroplating line. Background Art

[0002] Circuit board electroplating refers to the process of depositing a layer of metal coating on the inner wall of the conductor and via of the printed circuit board. This process reduces metal ions into metal atoms through electrochemical reaction and deposits them on the surface of the substrate. The main purpose of electroplating is to improve the conductivity, oxidation resistance and solderability of the circuit board. Through electroplating, the cross-sectional area of ​​the wire can be increased, the resistance can be reduced, and the current carrying capacity can be improved; at the same time, the electroplating layer can also protect the copper foil from oxidation and extend the service life of the circuit board. In addition, electroplating can also fill the vias, realize the interconnection of multi-layer boards, and improve the integration and reliability of printed circuit boards. In short, the electroplating process is an indispensable and important link in the manufacturing of modern electronic products, and plays a key role in improving product performance and reliability.

[0003] Washing the circuit board after electroplating is an important step, which can remove the residual plating solution and other impurities to ensure the quality of electroplating. Existing water washing devices for circuit boards mostly use water flow to wash, and the circuit board needs to be turned over many times to be cleaned. The operation is relatively cumbersome. If it is stirred in the cleaning solution, it may cause damage to the precision parts on the circuit board. Utility Model Content

[0025] like Figure 1 and Figure 2 As shown, a water cleaning device for a circuit board electroplating line includes a mounting base 1, a cleaning structure 2 is provided above the mounting base 1, a fixing ring 12 is fixedly connected above the mounting base 1 and corresponds to a liquid storage box 21, a slide groove 23 corresponding to the shape of a spiral slide rail 22 is provided on the inner side wall of the liquid storage box 21, the cleaning structure 2 includes a liquid storage box 21 that passes through the mounting base 1, a spiral slide rail 22 corresponding to the liquid storage box 21 is provided inside the liquid storage box 21, and a clamping structure 11 corresponding to the spiral slide rail 22 is provided at one end of the spiral slide rail 22.

[0026] In the present embodiment, a cleaning structure 2 is arranged above the mounting base 1, and a liquid storage box 21 in the cleaning structure 2 is used to store cleaning liquid. The circuit to be cleaned is fixed with the help of the clamping structure 11. When the clamping structure 11 slides inside the cleaning structure 2 along the spiral slide rail 22, the circuit board itself rotates and slides forward, thereby causing multi-angle relative movement with the cleaning liquid to ensure more thorough cleaning. Agitation is caused by the rotation of the circuit board itself to avoid damage to the circuit board during stirring. The utility model has a simple structure and is easy to use.

[0027] like Figure 3 and Figure 4 As shown, the interior of the slide groove 23 is provided with a sliding block 13 corresponding to itself and symmetrically distributed, and the side of the sliding blocks 13 close to each other is fixedly connected with a corresponding sleeve shell 14, and the side of the sleeve shell 14 close to the spiral slide rail 22 is provided with an opening 15, and the outside of the sleeve shell 14 is sleeved with a pair of limiting rings 24 corresponding to its own width, and the limiting rods 25 are fixedly connected between the limiting rings 24, and the spiral slide rail 22 is connected to the limiting rings 24. The width of the sliding block 13 is greater than the width of the sleeve shell 14, and the spacing between the sleeve shell 14 and the limiting rings 24 and the spiral slide rail 22 is the same. A fixing rod 17 is fixedly connected between the sleeve shells 14 through a spring 16, and a plurality of connecting rods 18 that are all distributed and correspond to the opening 15 are fixedly connected to the side of the fixing rod 17 close to the spiral slide rail 22, and the other end of the connecting rod 18 is connected to a spring clip 19.

[0028] In this embodiment, the movable rod on the side of the fixed rod 17 facing away from the spring clip 19 is connected with a pushing rod, which is convenient for pushing the clamping structure 11, and is convenient and practical; with the help of the sliding block 13, a more stable sliding is achieved between the sliding groove 23 and the spiral slide rail 22; the sleeve 14 is sleeved on both ends of the fixed rod 17 and connected through the spring 16, and the tension of the spring 16 can be used to tightly clamp the sliding block 13, the limit ring 24 and the spiral slide rail 22, thereby ensuring stable operation and achieving self-adjustment.

[0029] When using:

[0030] 1. Preparation:

[0031] Make sure that the mounting base 1 is firmly placed.

[0032] Check whether the cleaning structure 2 is correctly installed on the mounting base 1.

[0033] An appropriate amount of cleaning liquid is injected into the liquid storage box 21 .

[0034] 2. Loading the circuit board:

[0035] The clamping structure 11 is moved to the starting position of the spiral slide rail 22 using a push rod.

[0036] Open the spring clamp 19 and place the circuit board to be cleaned into the clamping structure 11 .

[0037] Make sure the circuit board is firmly held by the spring clips 19.

[0038] 3. Adjust the clamping structure:

[0039] If the size of the circuit board is different from the default setting, the position of the housing 14 can be adjusted by utilizing the elasticity of the spring 16 to adapt to circuit boards of different sizes.

[0040] 4. Start cleaning:

[0041] The clamping structure 11 is gently pushed by a push rod to start moving along the spiral slide rail 22 .

[0042] The clamping structure 11 drives the circuit board to rotate and move forward in the cleaning liquid.

[0043] 5. Cleaning process:

[0044] As the clamping structure 11 moves on the spiral slide rail 22 , the circuit board will automatically rotate and move forward.

[0045] The rotation of the circuit board will agitate the cleaning liquid, allowing multi-angle cleaning.

[0046] The sliding block 13 slides in the sliding groove 23 to ensure the stability of the whole process.

[0047] 6. Monitoring and cleaning:

[0048] Ensure that the cleaning process is proceeding smoothly by observing the movement of the circuit board.

[0049] If necessary, the moving speed of the clamping structure 11 can be adjusted using a push rod.

[0050] 7. Complete cleaning:

[0051] When the clamping structure 11 reaches the end of the spiral slide rail 22, the cleaning process ends.

[0052] 8. Take out the circuit board:

[0053] The clamping structure 11 is moved back to the starting position using the push rod.

[0054] Open the spring clip 19 and carefully take out the cleaned circuit board.

[0055] 9. Cleaning and maintenance:

[0056] After cleaning is completed, the waste liquid in the liquid storage box 21 is emptied.

[0057] Clean the liquid storage box 21, the spiral slide rail 22 and other parts.

[0058] Check each component for wear or damage and perform maintenance or replacement if necessary.

[0059] 10. Prepare for next use:

[0060] If necessary, the spiral guide rail 22 and the guide groove 23 may be lubricated to ensure smooth operation the next time they are used.

[0061] This design makes use of the spiral slide and the clamping structure to realize the automatic rotation and advancement of the circuit board, greatly improving the cleaning efficiency and quality. At the same time, its simple operation steps and maintenance requirements make it very suitable for practical industrial applications.
