Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PCB copper plating process, in particular to a slanted comb adjustable hanging basket. BACKGROUND

[0002] In the PCB manufacturing process, copper plating (or chemical copper plating) is a crucial process, which plays a role in chemically depositing a thin layer of copper on the surface of non-conductive substrate and the inner wall of through hole, laying the foundation for realizing interlayer electrical interconnection. In this process, the PCB board needs to be placed in a specially designed hanging basket and then immersed in a chemical bath for reaction.

[0003] At present, the industry generally uses a hanging basket with a slanted comb structure to carry the PCB board. The slanted design of the slanted comb uses the weight of the board to achieve preliminary positioning, so that the board leans against the comb teeth; however, in actual application, due to the need for frequent lifting and swinging of the hanging basket in the chemical bath during copper plating to promote chemical exchange, the slanted comb is a fixed design with fixed comb tooth spacing, which cannot closely fit PCB boards of different sizes. Under the impact of violent chemical shaking, the boards are prone to swing, collide with each other, or even stack, and in the worst case, they can completely fall out of the comb teeth.

[0004] At the same time, the fixed spacing of the hanging basket cannot optimize the flow field between the boards. When smaller boards are placed, the excessive spacing between the boards will lead to uneven chemical flow field, which may form a "dead water zone". The fixed arrangement also cannot achieve the best stirring effect, which will lead to inconsistent chemical update rates at different positions on the board, especially in deep holes, and poor supply of reactants and discharge of by-products, ultimately resulting in uneven copper plating thickness and affecting the quality and reliability of hole metallization.

[0005] However, there is an urgent need for a hanging basket with a slanted comb structure to solve the problems of board falling off and uneven copper plating thickness caused by fixed spacing. SUMMARY

DETAILED DESCRIPTION

[0021] For those skilled in the technical field, the technical solutions will be better understood, and the present application will be clearly and completely described below with reference to the drawings and in conjunction with the technical solutions in specific embodiments. Obviously, the description is exemplary, and the present application is not limited to this specific embodiment.

[0022] Please refer to Figure 1 and Figure 2 As shown in the drawings, the inclined plate comb adjustable hanging basket includes a hanging basket main frame 1, an L-shaped support frame 2, a support comb plate assembly 3, a connecting main frame 4, a rotating frame 5, a swing driving assembly 6 and a follow-up bubble generating assembly 7. The L-shaped support frame 2 is rotatably adjustable at both ends of the hanging basket main frame 1. The side wall and the bottom wall of the L-shaped support frame 2 are fixedly connected with the support comb plate assembly 3. The support comb plate assembly 3 is used for bearing and supporting the PCB board body 8. One end of the rotating frame 5 is fixedly connected with the upper surface of the hanging basket main frame 1. The upper end of the rotating frame 5 is rotatably connected with the bottom end of the connecting main frame 4. The swing driving assembly 6 is arranged between the connecting main frame 4 and the rotating frame 5. The swing driving assembly 6 is used for driving the rotating frame 5 to reciprocate, thereby driving the hanging basket main frame 1 to reciprocate. The follow-up bubble generating assembly 7 is further arranged at the L-shaped support frame 2. The follow-up bubble generating assembly 7 is composed of a fixed horizontal pipe 714, a bubble nozzle 715 and a linkage generator.

[0023] The adjustable support comb plate assembly 3 and the L-shaped support frame 2 can be adapted to and clamp PCB boards of different lengths and widths, effectively preventing the board body from being scattered and separated, thereby greatly improving the production safety and copper plating yield. In addition, through the linkage of the follow-up bubble generating assembly 7 and the swing driving assembly 6, the micro-bubble stirring can be started synchronously at the moment when the hanging basket swings and the exchange of chemical solution needs to be strengthened, thereby improving the copper plating uniformity and the utilization rate of the chemical solution, achieving energy saving and consumption reduction, and being particularly suitable for flexible and high-quality PCB copper plating production lines.

[0024] In a preferred embodiment, as shown in Figure 3 and Figure 4 The support comb plate assembly 3 is provided with a plurality of support comb plate assemblies 3. The plurality of support comb plate assemblies 3 are fixedly arranged at the bottom surface and the side wall of the L-shaped support frame 2. The cooperation of the support comb plate assembly 3 and the L-shaped support frame 2 constitutes stable support and limiting for the bottom and side of the PCB board body 8. Through the inclined arrangement, the center of gravity of the board body can be naturally biased towards the support point, combined with the tight clamping caused by the adjustable spacing, forming a multi-dimensional limiting guarantee, ensuring the stability of the board body under the shaking of the chemical solution.

[0025] In one specific selected embodiment, referring to Figure 5 As shown in the drawings, the support comb plate assembly 3 comprises a long strip seat 301 and a first support groove 302, both ends of the long strip seat 301 are provided with ear plates, the two end ear plates of the long strip seat 301 are fixedly connected between the L-shaped support frame 2, a plurality of first support grooves 302 are arranged on the long strip seat 301, the plurality of first support grooves 302 are equidistantly arranged, and are used for bearing the PCB plate body 8, a sliding groove inner cavity is arranged in the inside of the long strip seat 301, an adjusting seat 303 is slidably connected in the sliding groove inner cavity of the long strip seat 301, a second support groove 304 matched with the first support groove 302 is formed in the adjusting seat 303, through the technical solution, the actual width of the support opening formed by the first support groove 302 and the second support groove 304 can be changed by sliding the adjusting seat 303, so that the PCB plate of different thicknesses can be flexibly adapted, more accurate clamping can be realized, and the problem that the thin plate shakes due to too large gap or the thick plate cannot be placed can be avoided.

[0026] Further, as shown in the drawings, Figure 6 In order to realize the moving adjustment function of the adjusting seat 303, an inner cavity is arranged in the inside of the adjusting seat 303, an adjusting sliding block 305 is arranged in the inner cavity of the adjusting seat 303, the adjusting sliding block 305 is used for driving the adjusting seat 303 to move, a rotating adjusting rod 307 is also rotatably connected in the sliding groove inner cavity of the long strip seat 301, part of the rotating adjusting rod 307 is an adjusting screw rod 308, the adjusting screw rod 308 penetrates through the adjusting sliding block 305 and is in threaded connection with the adjusting sliding block 305, an adjusting knob 309 is rotatably connected at one side wall of the long strip seat 301, one end of the adjusting knob 309 is fixedly connected with one end of the rotating adjusting rod 307, through the technical solution, the rotating adjusting rod 307 can be driven to rotate by rotating the adjusting knob 309, then the adjusting sliding block 305 is driven to move along the adjusting screw rod 308 in the axial direction through the threaded pair, and then the entire adjusting seat 303 is pushed to slide relative to the long strip seat 301, the linear adjustment of the support opening width is realized, and the operation is simple and reliable and convenient to use.

[0027] Further, in order to make the adjusting seat 303 and the long strip seat 301 cooperate to produce a certain elastic pre-tightening force on the PCB plate body 8 when clamping, avoid the stress concentration or damage of the plate edge caused by rigid clamping, one end of a control spring 306 is fixedly connected with both side walls of the adjusting sliding block 305, the other end of the control spring 306 is fixedly connected with the inner cavity wall of the adjusting seat 303, and the adjusting sliding block 305 and the inner cavity of the adjusting seat 303 are in sliding connection. Through the technical solution, when the adjusting knob 309 is tightened, the adjusting sliding block 305 first compresses the control spring 306, the rebound force of the spring acts on the PCB plate body 8 through the adjusting seat 303, and a flexible clamping force is formed, through the above technical solution, not only the slight tolerance of the plate thickness can be adapted, but also the buffer can be provided to protect the plate body from being damaged.

[0028] Back to Figure 4 As shown in the figure, in order to realize the angle adjustment of the L-shaped support frame 2, so as to further optimize the support gravity center and the space utilization of the hanging basket for different size plate bodies, a rotating shaft 204 is arranged at the side wall of the L-shaped support frame 2, the rotating shaft 204 penetrates the bottom end of the hanging basket main body frame 1 and is rotationally connected with the hanging basket main body frame 1, and a connecting traction frame 201 is fixedly connected at the upper end position of the L-shaped support frame 2. A traction cylinder 202 is arranged between the connecting traction frame 201 and the hanging basket main body frame 1, and specifically, the two ends of the traction cylinder 202 are provided with hinged frames 203, one side of the hinged frame 203 is rotationally connected with the upper end of the connecting traction frame 201, and the other side of the hinged frame 203 is rotationally connected with the upper end of the hanging basket main body frame 1. Through the technical scheme, by controlling the extension and retraction of the traction cylinder 202, the L-shaped support frame 2 can be pulled by the connecting traction frame 201 to rotate around the rotating shaft 204 at the bottom as the axis, so as to change the inclination angle of the support comb plate assembly 3 on the side wall and the bottom wall of the L-shaped support frame 2, and make the hanging basket better adapt to different production rhythms and process requirements.

[0029] Please refer to Figure 7 The upper end of the rotating frame 5 is fixedly connected with a connecting shaft rod 501, the connecting shaft rod 501 penetrates the bottom end of the connecting main frame 4 and is rotationally connected with the bottom end of the connecting main frame 4, the swing driving assembly 6 includes a swing frame 601, a connecting rod 605, a linear slide 603 and a reciprocating driving part, the inside of the connecting main frame 4 is provided with an inner cavity, the linear slide 603 is slidingly connected in the inner cavity of the connecting main frame 4, the reciprocating driving part is used for driving the linear slide 603 to move reciprocally, a movable foot 604 is slidingly connected at the side wall of the connecting main frame 4, the movable foot 604 is fixedly connected between the linear slide 603, the two ends of the connecting shaft rod 501 are fixedly connected with the swing frame 601, a cross rod 602 is rotationally connected between one end of the two swing frames 601, one end of the movable foot 604 is rotationally connected with one end of the connecting rod 605, and the other end of the connecting rod 605 is fixedly connected with the cross rod 602. Through the technical scheme, when the reciprocating driving part pushes the linear slide 603 to move linearly and reciprocally, the cross rod 602 is moved through the movable foot 604 and the connecting rod 605, so as to convert the linear motion into the reciprocating swing of the swing frame 601 and the connecting shaft rod 501, and finally drive the whole hanging basket main body frame 1 to swing stably.

[0030] The reciprocating drive unit includes a rotating disk 607, a connecting frame 606, and a servo motor 609. The rotating disk 607 is rotatably connected to the inner cavity of the connecting main frame 4. One end of the connecting frame 606 is rotatably connected to an eccentric position on the side wall of the rotating disk 607. The other end of the connecting frame 606 is rotatably connected to the upper surface of the linear slider 603 via a connecting bracket 608. The servo motor 609 is also fixedly installed on the outer wall of the connecting main frame 4. The output shaft end of the servo motor 609 is connected to the center of the rotating disk 607 via a coupling. With this technical solution, the servo motor 609 can drive the rotating disk 607 to rotate at a uniform speed. Through the eccentrically positioned connecting frame 606, the rotational motion is converted into the uniform linear reciprocating motion of the linear slider 603. The mechanism designed above operates smoothly and has high reliability. Furthermore, the oscillation frequency and amplitude are easily controlled via the servo motor 609.

[0031] In the PCB copper plating process, the basket and the PCB it supports need to be immersed in a chemical solution bath. The surface of the PCB, especially the inner walls of the micropores formed after drilling, is prone to the adhesion and retention of gas when immersed in the solution. These air bubbles form "air cushions" that block the contact between the solution and the substrate, preventing copper from being deposited in that area. Therefore, the swing design of this application can improve the uniformity and reliability of the copper plating quality. Through forced convection, it ensures the uniform flow and exchange of the solution on the surface of the PCB and in each micropore, significantly improving the uniformity of the plating layer inside the holes, eliminating various plating defects caused by air bubbles and poor diffusion, and thus improving the product's pass rate and reliability.

[0032] As a preferred embodiment, see [reference] Figure 3 and Figure 8 As shown, the fixed horizontal tube 714 is fixedly installed at the bottom side of the L-shaped support frame 2. Several bubble nozzles 715 are fixedly installed on the fixed horizontal tube 714. The bubble nozzles 715 are used to spray compressed air from the linkage generator into the gap between the PCB boards 8 in the form of a large number of micro bubbles.

[0033] To optimize the bubble agitation effect and directly target the most critical areas for chemical exchange between boards, the number of bubble nozzles 715 matches the number of first support grooves 302 on the elongated board base 301. The bubble nozzles 715 are positioned between two first support grooves 302 to directly spray microbubble streams into the middle area between two adjacent PCB boards 8. The microbubble clusters generated by the bubble nozzles 715 violently agitate the chemical exchange between the PCB boards 8 during their ascent, effectively removing bubbles adhering to the board surface, renewing the diffusion boundary layer, and ensuring uniform exchange of copper plating solution on the board surface and in the gaps, thereby significantly improving the uniformity and consistency of the copper plating layer.

[0034] See Figure 2 , Figure 8 andFigure 9 The linkage generator comprises a fixed cylinder body 701, a reciprocating piston 703, a reciprocating guide rod 704 and a reciprocating moving seat 705, the upper end of the fixed cylinder body 701 is fixedly connected with a cylinder mounting frame 702, the cylinder mounting frame 702 is fixedly connected between the side wall of the connecting main frame 4, the reciprocating piston 703 is slidably connected in the inner cavity of the fixed cylinder body 701, the bottom surface of the reciprocating piston 703 is fixedly connected with one end of the reciprocating guide rod 704, the other end of the reciprocating guide rod 704 penetrates through the bottom wall of the inner cavity of the fixed cylinder body 701 and extends out of the wall, the bottom end of the reciprocating guide rod 704 is fixedly connected with the reciprocating moving seat 705, the reciprocating moving seat 705 is arranged at the side wall of the connecting main frame 4 and is slidably connected with the connecting main frame 4, and the reciprocating moving seat 705 is further fixedly connected with the linear slide 603, through the technical scheme, when the swing driving assembly 6 drives the linear slide 603 to make reciprocating motion, the reciprocating moving seat 705 and the reciprocating guide rod 704 can be synchronously driven to make up-down motion, so as to drive the reciprocating piston 703 to make reciprocating motion in the fixed cylinder body 701, the mechanical swing kinetic energy of the hanging basket is converted into the power of compressed gas, the pneumatic pump function without additional power driving is realized, and energy saving and linkage reliability are achieved.

[0035] Since in the copper plating process, when the hanging basket swings violently, the macro flow of the medicine is the strongest, and the bubble stirring is most needed for synergistic effect; and when the hanging basket is temporarily stationary, for example, the waiting time in the process rhythm, the continuous strong stirring not only wastes energy, but the violent disturbance generated may even have uncertain influence on some chemical steps that need a relatively stable environment.

[0036] Therefore, the timing control function of the embodiment is realized by mechanical linkage between the swing driving assembly 6 and the follow-up bubble generating assembly 7, specifically, as shown in Figure 2 、 Figure 7 、 Figure 9 The reciprocating moving seat 705 is fixedly connected with the linear slide 603, which means that the servo motor 609 drives the rotating disc 607 to rotate, and then converts the reciprocating motion of the linear slide 603 through the connecting frame 606, this motion realizes two effects, first, the hanging basket is driven to swing through the connecting rod 605; second, the reciprocating moving seat 705 and the reciprocating piston 703 are synchronously driven to move up and down, like a gas pump.

[0037] When the servo motor 609 drives the rotating disc 607 to rotate from 0 degree to 180 degrees, the linear slider 603 moves from one side limit position to the other side, pushes the cross bar 602 through the connecting rod 605, so that the hanging basket starts to swing, at the same time, the movement of the linear slider 603 drives the reciprocating moving seat 705 and the reciprocating piston 703 to move up or down in the fixed cylinder body 701, when the piston moves to the upper cavity of the compression cylinder body, the gas pressure in the cylinder rises, opens the one-way valve on the output gas pipe 706, and the compressed gas is pumped out, stabilized through the buffer tank 709, and then delivered to the bubble nozzle 715 to generate micro bubbles, realizing the timing function of "the hanging basket starts to swing, and the bubble stirring is automatically started".

[0038] When the copper deposition process is finished or the hanging basket needs to be stationary, the servo motor 609 stops rotating, the rotating disc 607 stops rotating, the linear slider 603 stops at a certain position, the reciprocating piston 703 also stops at a certain stroke position, the pneumatic pump function completely stops, no compressed gas is generated, and the micro bubble injection is automatically terminated, realizing the timing logic of "swinging to spray and stationary to stop".

[0039] Through the above technical scheme, the "on-demand supply" of pneumatic stirring is realized, the waste of energy during unnecessary process is avoided, and compared with the continuous gas injection scheme, a large amount of high-purity nitrogen or compressed air can be saved, and the operation cost is reduced.

[0040] Further, the inner cavity of the fixed cylinder body 701 is fixedly connected with an output gas pipe 706 and an input gas pipe 707 on the upper side, and one-way check valves are installed on the output gas pipe 706 and the input gas pipe 707. Specifically, the one-way valve on the input gas pipe 707 only allows the gas from the external gas source to enter the upper cavity of the fixed cylinder body 701, and the one-way valve on the output gas pipe 706 only allows the gas in the upper cavity of the fixed cylinder body 701 to be discharged. The input gas pipe 707 is used to be connected with the gas source for providing dry and clean nitrogen from outside, so as to ensure that the gas entering will not oxidize the copper deposition liquid and ensure the process quality. The output gas pipe 706 is used to be connected with the fixed cross pipe 714, so as to deliver the compressed gas generated by the linkage generator to each bubble nozzle 715.

[0041] Further, in order to smooth the pulse gas flow generated by the linkage generator, provide a continuous and stable bubble output, and buffer and overload protect the gas pressure, refer to Figure 8 and Figure 10As shown, the follow-up bubble generating assembly 7 also includes a buffer component for storing gas and stabilizing output pressure, which includes a buffer tank 709, a connecting piston 710 and a connecting spring 711. The buffer tank 709 is fixedly arranged at the upper surface of the hanging basket main body frame 1, and the connecting piston 710 is slidingly connected in the inner cavity of the buffer tank 709. The connecting piston 710 and the buffer tank 709 are dynamically sealed by a sealing ring, so as to divide the inner cavity of the buffer tank 709 into two cavities. One end of the connecting spring 711 is fixedly connected to the upper surface of the connecting piston 710, and the other end of the connecting spring 711 is fixedly connected to the upper wall of the inner cavity of the buffer tank 709. The connecting spring 711 is used to provide a force balanced with the gas pressure, so that the buffer tank 709 can absorb the gas pressure pulse. The inner cavity of the buffer tank 709 is also fixedly connected with an output hose 713 and a connecting pipe 708. The connecting pipe 708 is connected with the output gas pipe 706, and one end of the output hose 713 is connected with a fixed cross pipe 714. Through the technical solution, the pulse gas flow generated by the linkage generator first enters the lower cavity of the buffer tank 709, pushes the connecting piston 710 to compress the connecting spring 711, and converts the pulse kinetic energy of the gas into the potential energy of the spring. When the gas flow decreases, the spring releases the potential energy and pushes the piston to smoothly discharge the gas, so as to provide a stable and continuous gas flow to the bubble nozzle 715 through the output hose 713, so that the generation of micro-bubbles is more uniform.

[0042] Preferably, in order to prevent damage to components due to excessive system pressure caused by accidental circumstances, a safety valve 712 is also installed at the bottom side of the inner cavity of the buffer tank 709. The safety valve 712 is used to automatically release pressure when the pressure exceeds the set safety value. The safety valve 712 is configured to automatically open when the gas pressure in the lower cavity of the buffer tank 709 exceeds the preset threshold value, and the high-pressure gas is discharged to the atmosphere, thereby protecting the entire gas path system from overpressure damage and ensuring the safety of the equipment.
