Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a PCB copper plating line cleaning device. Background Technology

[0002] PCB, short for Printed Circuit Board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Electroless copper plating is a process where a thin layer of chemical copper is deposited onto the non-conductive hole walls of a pre-drilled substrate using chemical methods. This layer serves as the base for subsequent electroplating. Copper traces are the lines on the surface of the PCB. After electroless copper plating, the copper traces on the surface of the PCB need to be cleaned. Common methods for cleaning copper traces on the surface of the PCB include immersion cleaning, spray cleaning, and ultrasonic cleaning.

[0003] Existing ultrasonic cleaning methods typically involve placing circuit boards in a cleaning tank and utilizing the cavitation effect of ultrasound in the liquid to remove impurities. This technology is highly effective at removing contaminants from micropores and blind holes. Although it can also clean stubborn flux residues, cured adhesive residues, and dense oxide films with strong adhesion, it often relies on extending the cleaning time or increasing the power to achieve a thorough removal, resulting in low work efficiency. Furthermore, as the amount of contaminants in the cleaning solution increases with the duration of use, the contaminant particles absorb ultrasonic energy, reducing the generation and collapse efficiency of cavitation bubbles, leading to a significant decrease in cleaning effectiveness. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a PCB copper plating cleaning device to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB copper plating line cleaning device, comprising a cleaning tank, a motor installed at the bottom of the cleaning tank, a reciprocating lead screw connected to the output end of the motor, the top end of the reciprocating lead screw extending to the top of the cleaning tank and fixed with a turntable, a slider sleeved on the outer surface of the reciprocating lead screw, and frames connected to both sides of the slider, with brush bristles on the inner side of the frames, a piston box and a filter box respectively installed on the top of the cleaning tank, and the bottom of the filter box communicating with the cleaning tank, a lever fixed to the top of the turntable, and a linkage rod rotatably connected to the outer surface of the lever, a piston rod hinged to one end of the linkage rod, and a piston plate fixed to one end of the piston rod extending into the piston box, a suction pipe and a delivery pipe respectively connected to one side of the piston box, a first filter layer and a second filter layer provided inside the filter box; and a clamping assembly installed at the bottom of the cleaning tank.

[0006] Furthermore, the clamping assembly includes a clamping seat, and a screw and a guide rod are respectively connected to one side of the clamping seat. A clamping plate is provided on the outer surface of the guide rod of the screw. The clamping plate is threadedly connected to the screw and slidably connected to the guide rod. A clamping opening is provided on the top of the clamping plate and the top of the clamping seat. A knob is fixed to one end of the screw, and a rubber pad is provided on the inner side of the clamping opening.

[0007] By adopting the above technical solution, the staff inserts the bottom end of the PCB circuit board into the clamping slot of the clamping seat and the clamping plate, rotates the knob, and the screw rotates to make the clamping plate slide along the guide rod, clamping the bottom end of the PCB circuit board from both sides. The rubber pad inside the clamping slot is tightly attached to the bottom end and side of the PCB circuit board, so as to achieve a stable fixation of the bottom end.

[0008] Furthermore, corrugated telescopic tubes are fixed at the top and bottom of the slider. The top end of one set of corrugated telescopic tubes is fixed to the upper interior of the cleaning tank, and the bottom end of the other set of corrugated telescopic tubes is fixed to the lower interior of the cleaning tank. The reciprocating screw is located inside the two sets of corrugated telescopic tubes.

[0009] By adopting the above technical solution, the corrugated telescopic tubes at the top and bottom of the slider are connected to the upper and lower parts of the cleaning tank, respectively, completely enclosing the reciprocating screw. When the slider moves up and down with the screw, the corrugated telescopic tubes extend and retract synchronously, always sealing the screw area and forming a "dynamic protective cavity" to prevent impurities from getting stuck in the spiral groove on the outer surface of the reciprocating screw.

[0010] Furthermore, the slider slides into the helical groove on the outer surface of the reciprocating lead screw, and a slide rod is fixed inside the cleaning tank, with the slider sliding into the slide rod.

[0011] By adopting the above technical solution, when the motor drives the reciprocating screw to rotate, the helical groove drives the slider to move up and down along the axis of the reciprocating screw. At the same time, the sliding rod in the cleaning box slides with the slider, restricting the slider's rotational freedom and allowing it to only make linear reciprocating motion along the sliding rod. This ensures that the slider drives the frame and bristles to move up and down smoothly. This structure converts the rotational motion of the reciprocating screw into the linear motion of the slider through the helical groove. Combined with the rigid guidance of the sliding rod, it ensures the accuracy and stability of the slider's motion.

[0012] Furthermore, an ultrasonic generator is installed on the inner wall of the cleaning tank, and a control panel is installed on the upper surface of the outer surface of the cleaning tank. Both the ultrasonic generator and the motor are electrically connected to the control panel.

[0013] By adopting the above technical solution, staff can set parameters and start the equipment through the control panel, while simultaneously controlling the operation of the ultrasonic generator and the motor.

[0014] Furthermore, the first filter layer is made of PP woven mesh, and the second filter layer is made of PES polymer membrane material.

[0015] By adopting the above technical solution, when the cleaning fluid in the piston box is pressed into the filter box through the infusion pipe, the PP woven mesh first filters out large particulate impurities with a particle size ≥50μm (such as PCB detachment and brush hair debris), and the PES polymer membrane material further intercepts fine pollutants with a particle size ≥5μm (such as cured adhesive particles and metal oxides), thus achieving graded purification of "coarse filtration + fine filtration".

[0016] Furthermore, both the cleaning box and the filter box are equipped with waterproof and sealed doors on their outer surfaces, and both the first filter layer and the second filter layer are detachably installed from the filter box.

[0017] By adopting the above technical solution, the PCB circuit board can be easily installed and removed through the waterproof and sealed door. When maintenance is required, the staff can easily remove the contaminated filter layer for cleaning or replacement by opening the waterproof and sealed door.

[0018] Furthermore, the cleaning tank has a liquid inlet on one side of its top and a drain pipe on the lower side of one side, with a valve on the outer surface of the drain pipe.

[0019] By adopting the above technical solution, the liquid inlet on the top of the cleaning tank is used to inject cleaning fluid. Workers can add the cleaning fluid directly into the tank through this port. The valve on the drain pipe controls the discharge of waste liquid. After cleaning is completed, the valve is opened and the waste liquid is discharged through the drain pipe.

[0020] Furthermore, one end of the suction tube is connected to the cleaning tank, and one end of the infusion tube is connected to the cleaning tank, and both the suction tube and the infusion tube are equipped with a one-way valve.

[0021] By adopting the above technical solution, the one-way valve of the suction pipe allows the cleaning fluid to flow from the cleaning tank into the piston box, and the one-way valve of the delivery pipe ensures that the liquid can only be forced into the filter box from the piston box. When the turntable drives the piston rod through the lever to make the piston plate reciprocate in the piston box, the piston moves to the left to create negative pressure, the one-way valve of the suction pipe opens and the one-way valve of the delivery pipe closes, and the cleaning fluid is sucked into the piston box; when the piston moves to the right, the pressure increases, the one-way valve of the delivery pipe opens and the one-way valve of the suction pipe closes, and the cleaning fluid is forced into the filter box, realizing directional flow.

[0022] Furthermore, the bristles are made of nylon 612 material, and the frame is detached and set by bolts and sliders.

[0023] By adopting the above technical solution, the high hardness and low coefficient of friction of nylon 612 material can effectively remove stubborn stains while avoiding scratching the board surface. After the bristles wear out, they can be quickly replaced by removing the bolts to maintain a stable physical friction cleaning force. The detachable frame structure also makes it easy to adjust the bristle installation position or replace bristle components of different densities according to the size of the PCB board, improving the adaptability of the device to diverse cleaning needs.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the arrangement of a reciprocating lead screw, a slider, a frame, and brush bristles, uses a motor rotation to rotate the reciprocating lead screw, which in turn causes the slider to move up and down in a regular manner. This causes the frame to move the brush bristles up and down. While the ultrasonic cavitation effect loosens the contaminants, the mechanical friction of the brush bristles directly peels off stubborn residues, forming a dual effect of "cavitation breaking + physical peeling". Compared with single ultrasonic cleaning, this speeds up the cleaning process and improves work efficiency. The frame is detachable from the slider using bolts. The detachable frame structure also makes it easy to adjust the brush bristle installation position or replace brush bristle components of different densities according to the size of the PCB circuit board, improving the adaptability of the device to diverse cleaning needs.

[0026] 2. This utility model, through the arrangement of a turntable, lever, linkage rod, piston plate, piston rod, piston box, first filter layer, and second filter layer, allows the turntable to rotate when the reciprocating screw rotates. The lever then drives the linkage rod to swing, causing the piston rod to move the piston plate within the piston box. The suction pipe draws the cleaning fluid into the piston box, and the delivery pipe feeds the cleaning fluid into the filter box. The first filter layer performs coarse filtration of the cleaning fluid, and the second filter layer performs fine filtration, thereby reducing the content of contaminants in the cleaning fluid and preventing contaminants from absorbing ultrasonic energy and reducing the cleaning ability of the ultrasonic waves. Furthermore, because the cleaning fluid is filtered in real time, contaminants are prevented from re-adhering to the PCB circuit board and causing secondary pollution when the cleaning fluid is discharged later, further improving the cleaning effect. Moreover, the linkage-based real-time filtration eliminates the need for additional power, saving on device costs. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1: A PCB copper plating line cleaning device, such as Figures 1-5As shown, the system includes a cleaning tank 1. A liquid inlet 5 is located on one side of the top of the cleaning tank 1. A drain pipe 15 is located on the lower side of the cleaning tank 1. A valve is provided on the outer surface of the drain pipe 15. The liquid inlet 5 on the top of the cleaning tank 1 is used to inject cleaning fluid, allowing workers to directly add the cleaning fluid into the tank. The valve on the drain pipe 15 controls the discharge of waste fluid. After cleaning, the valve is opened, and the waste fluid is discharged through the drain pipe 15. A motor 3 is installed at the bottom of the cleaning tank 1. The output end of the motor 3 is connected to a reciprocating lead screw 17, and the top end of the reciprocating lead screw 17 extends to the top of the cleaning tank 1 and is fixed with a turntable 8. A slider 18 is sleeved on the outer surface of the reciprocating lead screw 17. The slider 18 slides in a helical groove on the outer surface of the reciprocating lead screw 17. A slide rod 19 is fixed inside the cleaning box 1, and the slider 18 slides in a sliding engagement with the slide rod 19. When the motor 3 drives the reciprocating lead screw 17 to rotate, the helical groove causes the slider 18 to move up and down along the axis of the reciprocating lead screw 17. Simultaneously, the slide rod 19 inside the cleaning box 1 slides in a sliding engagement with the slider 18, restricting the rotational freedom of the slider 18 so that it can only perform linear reciprocating motion along the slide rod 19. This ensures that the slider 18 drives the frame 20 and brush bristles 25 to move smoothly up and down. This structure converts the rotational motion of the reciprocating lead screw 17 into linear motion of the slider 18 through the helical groove, and combined with the rigid guidance of the slide rod 19, ensures the accuracy and stability of the slider 18's movement. The sliding block 18 has frames 20 connected to both sides, and brush bristles 25 are provided on the inner side of the frames 20. A piston box 12 and a filter box 6 are respectively installed on the top of the cleaning box 1, and the bottom of the filter box 6 is connected to the cleaning box 1. A lever 9 is fixed to the top of the turntable 8, and a linkage rod 10 is rotatably connected to the outer surface of the lever 9. A piston rod 11 is hinged to one end of the linkage rod 10, and one end of the piston rod 11 extends into the interior of the piston box 12 and is fixed with a piston plate 22. A suction pipe 14 and an infusion pipe 13 are respectively connected to one side of the piston box 12. One end of the suction pipe 14 is connected to the cleaning box 1, and one end of the infusion pipe 13 is connected to the cleaning box 1. Both pipe 14 and infusion pipe 13 are equipped with one-way valves. The one-way valve on the suction pipe 14 allows the cleaning fluid to flow from the cleaning tank 1 into the piston box 12, while the one-way valve on the infusion pipe 13 ensures that the liquid can only be forced into the filter box 6 from the piston box 12. When the turntable 8 drives the piston rod 11 through the lever 9 to make the piston plate 22 reciprocate in the piston box 12, the piston moves to the left to create a negative pressure, the one-way valve on the suction pipe 14 opens and the one-way valve on the infusion pipe 13 closes, and the cleaning fluid is drawn into the piston box 12. When the piston moves to the right, the pressure increases, the one-way valve on the infusion pipe 13 opens and the one-way valve on the suction pipe 14 closes, and the cleaning fluid is forced into the filter box 6, realizing directional flow. The filter box 6 is provided with a first filter layer 23 and a second filter layer 24 inside.A clamping assembly 16 is installed at the lower interior of the cleaning tank 1. The clamping assembly 16 includes a clamping seat 1601, and a screw 1603 and a guide rod 1604 are respectively connected to one side of the clamping seat 1601. A clamping plate 1602 is provided on the outer surface of the guide rod 1604 of the screw 1603. The clamping plate 1602 is threadedly connected to the screw 1603 and slidably connected to the guide rod 1604. The top of the clamping plate 1602 and the top of the clamping seat 1601 are provided with openings. The clamp 1606 has a knob 1605 fixed to one end of the screw 1603. A rubber pad is provided on the inner side of the clamp 1606. The operator inserts the bottom end of the PCB circuit board into the clamp 1606 between the clamping seat 1601 and the clamping plate 1602. Rotating the knob 1605 causes the screw 1603 to rotate, causing the clamping plate 1602 to slide along the guide rod 1604, clamping the bottom end of the PCB circuit board from both sides. The rubber pad on the inner side of the clamp 1606 tightly adheres to the bottom end and sides of the PCB circuit board, achieving a stable fixation of the bottom end.

[0036] See Figure 2 In the above embodiment, an ultrasonic generator 21 is installed on the inner wall of the cleaning tank 1, and a control panel 4 is installed above the outer surface of the cleaning tank 1. The ultrasonic generator 21 and the motor 3 are both electrically connected to the control panel 4. The operator sets parameters and starts the equipment through the control panel 4, and controls the operation of the ultrasonic generator 21 and the motor 3 at the same time.

[0037] See Figures 2-3 In the above embodiments, the first filter layer 23 is made of PP woven mesh, and the second filter layer 24 is made of PES polymer membrane material. When the cleaning fluid in the piston box 12 is pressed into the filter box 6 through the infusion pipe 13, the PP woven mesh first filters out large particulate impurities with a particle size ≥50μm (such as PCB detachment and brush bristle 25 debris), and the PES polymer membrane material further intercepts fine pollutants with a particle size ≥5μm (such as cured adhesive particles and metal oxides), realizing graded purification of "coarse filtration + fine filtration".

[0038] See Figure 1 In the above embodiments, the outer surfaces of the cleaning box 1 and the filter box 6 are both equipped with waterproof sealing doors 2, and the first filter layer 23 and the second filter layer 24 are detached from the filter box 6. The waterproof sealing doors 2 facilitate the installation and removal of the PCB circuit board. When maintenance is required, the staff can open the waterproof sealing doors 2 to easily remove the contaminated filter layer for cleaning or replacement.

[0039] See Figures 2-3In the above embodiments, the bristles 25 are made of nylon 612 material, and the frame 20 is detached and connected to the slider 18 by bolts. Utilizing the high hardness and low coefficient of friction of nylon 612 material, it can effectively remove stubborn stains while avoiding scratching the board surface. Moreover, the bristles 25 can be quickly replaced by removing the bolts after wear, maintaining a stable physical friction cleaning force. The detachable frame 20 structure also makes it easy to adjust the installation position of the bristles 25 or replace the bristle 25 components with different densities according to the size of the PCB board, improving the adaptability of the device to diverse cleaning needs.

[0040] Example 2: To prevent cleaning fluid and impurities from entering the screw groove and causing transmission failure, Example 2 is an improvement on Example 1. (See attached document for details.) Figure 2 and Figure 4 The top and bottom of the slider 18 are both fixed with corrugated telescopic tubes 7. The top of one set of corrugated telescopic tubes 7 is fixed to the upper part of the inside of the cleaning tank 1, and the bottom of the other set of corrugated telescopic tubes 7 is fixed to the lower part of the inside of the cleaning tank 1. The reciprocating screw 17 is located inside the two sets of corrugated telescopic tubes 7. The corrugated telescopic tubes 7 at the top and bottom of the slider 18 are respectively connected to the upper and lower parts of the inside of the cleaning tank 1, completely enclosing the reciprocating screw 17. When the slider 18 moves up and down with the screw, the corrugated telescopic tubes 7 extend and retract synchronously, always sealing the screw area and forming a "dynamic protective cavity" to prevent impurities from getting stuck in the spiral groove on the outer surface of the reciprocating screw 17.

[0041] The implementation principle of this utility model is as follows: The operator places the PCB circuit board into the clamping assembly 16 and rotates the knob 1605 to make the clamp 1606 clamp the bottom of the PCB circuit board through the rubber pad; after injecting cleaning fluid from the liquid inlet 5, the ultrasonic generator 21 is started through the control panel 4 to generate a cavitation effect in the cleaning fluid, which initially loosens and peels off the contaminants on the surface of the copper lines and in the micropores of the PCB circuit board; after several seconds, the motor 3 is started to drive the reciprocating screw 17 to rotate, which drives the slider 18 to move up and down along the slide bar 19, so that the nylon 612 bristles 25 on the frame 20 begin to cooperate with the ultrasonic vibration to physically rub off the loosened stubborn contaminants (such as flux residue and oxide film);

[0042] Meanwhile, the top turntable 8 of the reciprocating screw 17 rotates and drives the piston rod 11 via the lever 9 and linkage rod 10 to drive the piston plate 22 inside the piston box 12 to reciprocate. The cleaning solution is drawn from the bottom of the cleaning tank 1 into the filter tank 6 through the liquid extraction pipe 14, the liquid delivery pipe 13 and the one-way valve. After passing through the first filter layer 23 of PP woven mesh for coarse filtration and the second filter layer 24 of PES polymer membrane material for fine filtration, it flows back to the cleaning tank 1. The online real-time filtration removes pollutant particles from the cleaning solution.

[0043] After cleaning, the staff opens the drain pipe 15 valve to discharge the waste liquid. The worn bristles 25 or the contaminated first filter layer 23 and second filter layer 24 can be disassembled and replaced through the waterproof sealing door 2.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
