Description

Technical Field

[0001] The invention belongs to the field of circuit board processing, and in particular relates to a circuit board cleaning device. Background Art

[0002] A PCB (Printed Circuit Board), also known as a printed circuit board (PCB), is a crucial electronic component that supports and connects electronic components. Because it's manufactured using electronic printing technology, it's called a "printed" circuit board. A PCBA (Printed Circuit Board Assembly) (PCBA) is a PCB that has undergone the PCBA process. PCBA involves the entire manufacturing process from a bare PCB to surface-mounted components (SMT) or dipped-in-place (DIP) components. During the soldering process on a PCB, flux is applied to remove oxides and reduce surface tension on the materials being soldered. However, some flux residue remains on the board during this process. This residual flux can easily absorb oil, dust, and moisture from the air, posing a threat to the PCBA's operational stability and potentially affecting the overall system's operation.

[0003] When cleaning PCBs, existing devices can only clean one surface at a time, resulting in incomplete cleaning. After cleaning, the PCB remains horizontal. Due to the surface tension of water, the cleaning liquid forms an almost impenetrable film at the edge of the PCB. The cleaning liquid does not flow down quickly after cleaning and is easily left on the PCB, resulting in slow drying and affecting production efficiency.

[0004] Therefore, a circuit board cleaning device is needed. Summary of the Invention

[0009] Preferably, the elastic buckle includes a hook-shaped moving block, and a spring is provided behind the hook-shaped moving block.

[0010] Preferably, straight teeth are evenly arranged on the outside of the vibration gear, and the straight teeth match the four sides of the product to be cleaned.

[0011] In summary, the present invention includes at least one of the following beneficial technical effects:

[0012] The present invention ensures the cleaning quality of the circuit board by setting a fixed clamp in the circuit board cleaning device and improving the cleaning process. At the same time, it also achieves the effect that originally required high-cost equipment to a certain extent with a simple structure. It is a good improvement that can reduce costs while improving efficiency, and can achieve the purpose of lean production to a certain extent.

[0013] The present invention, through the arrangement of a fixed cleaning device and the arrangement of an arc-shaped connecting rod and a rotating disk, can achieve uniform adjustment of the distance between multiple products through a single power source.

The same power source is used for clamping the product and vibrating cleaning, which greatly reduces the production cost to a certain extent. At the same time, the cleaning effect is significant. It is a very good high-efficiency, low-cost mechanical equipment. BRIEF DESCRIPTION OF THE DRAWINGS

An arc-shaped connecting rod 605 is fixed on the rotation, and the other end of the arc-shaped connecting rod 605 can be rotatably fixed on the rotating disk 606. The rotating disk 606 is a square structure with an internal gear. A support seat 607 is provided on the other side of the moving block 603. A torsion spring 608 is provided between the support seat 607 and the moving block 603. Four elastic clips 10 are fixed on the support seat 607. The product to be cleaned 11 is fixed on the support seat 607. A vibration gear 612 is provided at the corresponding position below the rotating disk 606, and the vibration gear 608 is connected to the driving motor 601.

[0025] Specifically, the cleaning area 7 and the water exchange area 8 are interconnected through an isolation layer 12, and the water exchange area 8 is connected to the outside through a water pipe.

[0026] Specifically, the pneumatic push rod 604 and the moving block 603 are connected and fixed via a connecting rod 609 . A slide rail 610 is provided on the circular guide plate 602 , and the moving block 603 matches the slide rail 610 .

[0027] Specifically, the elastic buckle 10 includes a hook-shaped moving block 1001 , and a spring 1002 is provided behind the hook-shaped moving block 1001 .

[0028] Specifically, straight teeth 611 are evenly arranged on the outside of the vibration gear 608, and the straight teeth 611 match the four sides of the product to be cleaned 11.

[0029] Working principle:

[0030] When the product needs to be cleaned, the rotary cover 4 is opened, and the circuit board is sequentially inserted into the elastic buckle 10 on the support seat 607, and then the drive motor 601 is started to rotate. At this time, the drive motor 601 is connected to the rotating disk 606 through a gear. At this time, the rotating disk 606 rotates, and the rotating disk 606 rotates through the arc connecting rod 605 to drive the moving block 603 to move inward along the slide rail 610. At this time, the distance between the circuit board and the vibration gear 612 is adjusted according to the size of the circuit board to ensure that the circuit board and the vibration gear 612 are just in contact. Then, by pressing the vibration gear 612, the drive motor 601 and the rotating disk 606 are separated from each other. At this time, the drive motor 601 only drives the vibration gear 612 to rotate, and then the rotary cover 4 is closed. At this time, the circuit board Sinking into the cleaning liquid, the vibration gear 612 continues to rotate. During the rotation of the vibration gear 612, it will touch the circuit board 11 to be cleaned, and drive the circuit board a distance. The support seat 607 of the circuit board and the moving block 603 are rotatably connected, and a torsion spring 608 is provided. When the support seat 607 rotates a certain angle under the drive of the vibration gear 612, the circuit board and the vibration gear 612 are separated, and the circuit board returns to its original position under the action of the torsion spring 608 until it touches the straight teeth 611 of the next vibration gear 612, and then continues the current movement state. At this time, the circuit board will vibrate back and forth continuously, and at the same time, it will also drive the full mixing of the cleaning liquid to ensure the cleaning effect of the circuit board, and at the same time it can also well promote the falling of attachments that are difficult to fall off on the circuit board.

[0031] When the cleaning work is finished, stop the driving motor, open the rotary cover 4, press the vibration gear 612 to connect the driving motor with the rotating disk 606, and the driving motor works to make the moving block 603 return to its original position. Take out the cleaned circuit board and the work is finished.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
