Description

Technical Field

[0001] This invention relates to the field of pretreatment board anti-oxidation technology, specifically to an anti-oxidation treatment device for PCB boards. Background Technology

[0002] Printed circuit boards (pre-processing boards) are indispensable core components in electronic devices, playing a crucial role in electrical connection and mechanical support. With the booming development of the electronics industry, the application fields of pre-processing boards are constantly expanding, covering numerous industries such as consumer electronics, communication equipment, automotive electronics, and aerospace. Their quality and reliability directly affect the performance and lifespan of the entire electronic product. During the manufacturing process, due to the high chemical activity of the copper foil surface, pre-processing boards are highly susceptible to chemical reactions with oxygen, moisture, and other impurities in humid air, environments containing corrosive gases, or during storage, leading to oxidation of the copper foil surface. Oxidized copper foil not only affects the conductivity of the pre-processing board, causing signal attenuation and distortion, and reducing circuit stability and reliability, but also affects the wettability of solder during subsequent soldering processes, leading to poor soldering, such as cold solder joints and other problems. This seriously affects the assembly quality and production efficiency of electronic products. As electronic products develop towards miniaturization, high density, and high performance, the circuits and pads on pre-processing boards are becoming increasingly intricate, and the requirements for anti-oxidation are becoming increasingly stringent. Therefore, effective anti-oxidation treatment of pre-processing boards has become a crucial step in the electronic manufacturing process.

[0003] Existing technologies still have some shortcomings. The cleaning process is particularly problematic. Existing equipment struggles to completely remove the cleaning solution from the pre-treated board surface after cleaning. Residual cleaning solution reacts chemically with the subsequent soaking solution, altering its chemical composition and properties. This change directly affects the pre-treated board surface, forming impurities and dirt, reducing micro-etching quality, and causing the surface roughness to fail to meet standards. This reduces the precision and clarity of the circuitry, ultimately impacting the product's electrical performance and reliability. During soaking, the fixed position of the pre-treated board results in poor fluidity of the soaking solution. Due to the lack of effective flow, the solution cannot evenly cover and act on all parts of the pre-treated board. Some areas suffer from excessive micro-etching due to prolonged soaking, while others experience poor micro-etching and inadequate surface treatment due to insufficient soaking. This severely affects the uniformity of micro-etching, leading to inconsistent quality within the same batch of pre-treated boards. Regarding liquid treatment, existing technologies lack an effective mechanism for recycling and reusing the cleaning and soaking solutions after use. Large amounts of waste liquid containing heavy metal ions and chemicals are directly discharged, causing significant resource waste and severe environmental pollution. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this solution, by setting up a cleaning component and through a multi-stage clamping and flipping design, the pretreatment plate cleaning process is highly efficient, automated and precisely controlled. By utilizing the coordinated movement of the upper flipping plate and the sliding stage, the position of the pretreatment plate can be flexibly adjusted. It is initially fixed by the clamping strip, and then the precise cooperation of the vertical clamping plate and the side clamping plate ensures that the pretreatment plate is stable and accurately positioned during cleaning. After the cleaning liquid is sprayed, the movement of the limiting sleeve is driven by the servo motor, so that the bottom slider contacts the bottom protrusion to generate vibration, which shakes the cleaning liquid away, effectively preventing the cleaning liquid from reacting with the subsequent soaking liquid and ensuring the surface treatment quality of the pretreatment plate.

[0017] 2. In this solution, by setting up an immersion component, the combination of vertical sliding rail, internal hydraulic rod and clamping claws realizes the smooth transition and precise positioning of the pretreatment plate from cleaning to immersion process, ensuring that the pretreatment plate accurately enters the immersion tank for micro-etching treatment. At the same time, the water transfer component uses the receiving frame to collect the immersion liquid removed by vibration, and the bottom motor drives the steering box to flexibly adjust the water flow path, realizing the classified storage of different liquids, effectively avoiding the adverse effects of liquid mixing;

[0018] 3. In this solution, the efficient recycling of cleaning and soaking solutions is achieved by incorporating a water-guiding component. A filter box and purification filter plate are used to deeply filter and purify the cleaning solution, extracting beneficial components to create a concentrated solution that replenishes the soaking solution, thus improving resource utilization. Compared to traditional methods of direct discharge or simple recycling of cleaning solutions, this solution achieves efficient recycling of both cleaning and soaking solutions, increases resource utilization, and reduces production costs. The water-driven rod converts the kinetic energy of the liquid flow into electrical energy and stores it, powering the control motor to rotate the disc, promoting the flow of the soaking solution and enhancing the soaking effect.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1 to 9 A PCB board anti-oxidation treatment device, comprising:

[0031] The main frame 1 is made of high-strength, corrosion-resistant metal material to ensure the stability and reliability of the device during long-term use. A spray box 5 is installed on the upper surface of the main frame 1, containing multiple precision nozzles that can evenly spray the anti-oxidation treatment liquid, providing comprehensive protection for the pretreatment plate 19. A liquid tank bottom plate 12 is installed below the main frame 1, also made of corrosion-resistant material. An immersion tank 17 is installed on its upper surface to hold a specific treatment liquid for immersing the pretreatment plate 19. The liquid tank bottom plate 12 is connected to the main frame 1 by evenly distributed uprights to ensure the structural strength of the entire device. The upper surface of the main frame 1 is provided with a micro-etching mechanism, which includes a cleaning component and an immersion component. The cleaning component includes a sliding stage 2, which is disposed on the upper surface of the main frame 1. One side surface of the sliding stage 2 is also provided with a groove, and a bottom protrusion 4 is provided on one side of the groove. A limiting sleeve 25 is provided inside the groove, and a bottom slider 23 is provided on the bottom surface of the limiting sleeve 25. A rear engagement block 24 is provided on one side surface of the limiting sleeve 25. Elastic connecting blocks 20 are provided on both the upper and lower surfaces of the rear engagement block 24. One side surface of the elastic connecting block 20 is connected to the inner side surface of the limiting sleeve 25. A servo motor is also provided on one side surface of the sliding stage 2. The output shaft of the servo motor 62 meshes with the rear meshing block 24. When the servo motor 62 starts, the rotation of the output shaft drives the rear meshing block 24 to move, thereby causing the limiting sleeve 25 to move linearly within the slide groove. A sliding clamping frame 6 is provided on the side of the limiting sleeve 25 facing away from the rear meshing block 24. The upper and lower surfaces of the sliding clamping frame 6 are connected to vertical clamping plates 18 via small electric shafts. A small motor 21 is provided inside the sliding clamping frame 6. A bidirectional meshing rod 22 is provided on the output end of the small motor 21. Two sliding side clamping plates 7 mesh with the surface of the bidirectional meshing rod 22. A pretreatment plate 19 is clamped between the two sliding side clamping plates 7. The upper surface of the frame 1 is also provided with a sliding groove platform 61, the upper surface of the sliding groove platform 61 is provided with a movable platform 8, the bottom surface of the movable platform 8 is provided with a bottom pulley 46, the upper surface of the movable platform 8 is provided with a lower flip plate 44, the connection between the lower flip plate 44 and the movable platform 8 is provided with an electric rotating shaft 45, the upper surface of the lower flip plate 44 is provided with an upper flip plate 40, the connection between the upper flip plate 40 and the lower flip plate 44 is also provided with an electric rotating shaft 45, one side surface of the upper flip plate 40 is provided with a micro motor 42, the output end of the micro motor 42 is provided with a micro screw 43, and the surface of the micro screw 43 is engaged with two clamping bars 41;

[0032] In real-world environments, before performing anti-oxidation treatment on the pre-treated board 19, an oxide layer inevitably forms on its surface during manufacturing, transportation, and storage. It may also become contaminated with dust, oil, fingerprints, and other pollutants. These oxide layers and contaminants hinder the direct contact between the subsequent anti-oxidation treatment agent and the copper substrate, affecting the effectiveness of the anti-oxidation treatment. Micro-etching, using a chemical solution, reacts with the oxide layer and contaminants on the board surface, dissolving and removing them, thus exposing the copper substrate. This provides a clean and fresh surface for subsequent anti-oxidation treatment. The micro-etching process creates a certain degree of roughness on the surface of the pre-treated board 19. This rough surface increases the contact area between the board and the subsequent anti-oxidation coating, improving the adhesion between the coating and the substrate. The adhesion between the plates is addressed during use. The equipment cleans the pretreatment plate 19 using a cleaning component. First, the operator places the pretreatment plate 19 on the upper surface of the upper flip plate 40 and starts the micro motor 42 via a signal drive, thus initially fixing the pretreatment plate 19 with the two clamping bars 41. Then, the movable platform 8 slides on the upper surface of the sliding groove platform 61 under signal control, moving closer to the sliding platform 2. Once in the designated position, the electric rotating shaft 45 drives the upper flip plate 40 to rotate, flipping the upper flip plate 40 and the pretreatment plate 19 to an upright position. Subsequently, the operator controls a small electric shaft to drive the vertical clamping plate 18 to initially vertically clamp and position the pretreatment plate 19. Driven by the micro motor 42, the holding bar 41 moves away from the pretreatment plate 19, losing its clamping effect on the pretreatment plate 19, and returns to its original position under the action of the movable platform 8. At this time, the operator drives the small motor 21 to rotate the bidirectional meshing rod 22, causing the two sliding side clamping plates 7 to move closer to each other, achieving precise lateral clamping of the pretreatment plate 19, thus completing the stable clamping effect of the pretreatment plate 19. Subsequently, the servo motor 62 starts, its output shaft rotates and meshes with the rear meshing block 24, driving the limiting sleeve block 25 to move in the slide groove of the sliding platform 2. The bottom slider 23 slides along the bottom protrusion 4 to ensure the stability of the movement. As the limiting sleeve block 25 moves, it drives the pretreatment plate 19 to the bottom of the spray box 5 and stops. Then, it is sprayed... The spray box 5 sprays cleaning fluid onto the surface of the pretreatment plate 19. Because the surface of the vertical clamping plate 18 has an opening, the cleaning fluid sprayed from the spray box 5 can clean both sides of the pretreatment plate 19 simultaneously. After spraying, the servo motor 62 drives the limiting sleeve 25 to continue moving inside the slide groove. The bottom slider 23 on its bottom surface gradually contacts the bottom protrusion 4 inside the slide groove as it moves, causing the entire limiting sleeve 25 to vibrate the pretreatment plate 19, thereby shaking off the cleaning fluid from the surface of the pretreatment plate 19. This completely removes the cleaning fluid from the surface of the pretreatment plate 19 before the soaking process begins, preventing a reaction between the cleaning fluid and the soaking solution, which could adversely affect the surface of the pretreatment plate 19.The cleaning solution dripping from the surface of the pretreatment plate 19 is collected by the water transfer component of the immersion assembly.

[0033] The immersion assembly includes: a vertical sliding rail 14, made of high-strength, corrosion-resistant metal, with its bottom surface connected to one side surface of the liquid tank bottom plate 12; an internal hydraulic rod 32 inside the vertical sliding rail 14; a lifting frame 15 at the end of the output shaft of the internal hydraulic rod 32; a connecting platform 33 at one end of the lifting platform 15; the connecting platform 33 providing the mounting base for the subsequent clamping structure; two miniature telescopic rods 34 on the upper surface of the connecting platform 33; clamping claws 36 at the end of the output shaft of each of the two miniature telescopic rods 34; and a limiting base 35 fitted onto the surface of the clamping claws 36. 35 serves to limit and stabilize the clamping claw 36, preventing it from shaking or shifting during clamping. The soaking assembly also includes a water-converting component, which includes a receiving frame 3. The receiving frame 3 adopts a sealed design to effectively prevent leakage of the treatment liquid. The receiving frame 3 is located on the upper surface of the main frame 1, and a drain outlet is provided on one side of the bottom surface of the receiving frame 3. A bottom connecting box 47 is provided on the bottom surface of the main frame 1. The interior of the bottom connecting box 47 is connected to the drain outlet, serving to collect and guide the treatment liquid. A deflector box 48 is provided on the bottom surface of the bottom connecting box 47, which can control and guide the flow direction of the treatment liquid according to different treatment needs. The treatment fluid is transported to the appropriate location. A water inlet block 49 is provided on one side of the diverting box 48. A bottom motor 9 is provided on the bottom surface of the diverting box 48, which is the power source for the water-turning component. A fixed platform 11 is provided on the bottom surface of the bottom motor 9, which provides stable support for the bottom motor 9 to ensure that it does not shake or shift during operation. Two limiting frames 50 are provided on the upper surface of the fixed platform 11. Liquid storage tanks 10 are provided on both sides of the fixed platform 11. The liquid storage tanks 10 are made of corrosion-resistant and well-sealed materials, which can store the treatment fluid for a long time without leakage or deterioration. The two liquid storage tanks 10 are used to store the treatment fluid. The storage tank 10 is equipped with a water inlet pipe on its upper surface. Multiple filler filter plates 27 are installed at the center of the water inlet pipe. A connector 28 is installed on one side of the upper surface of the water inlet pipe. A telescopic hose 30 is connected between the connector 28 and the water inlet pipe. The telescopic hose 30 has good flexibility and telescopicity. A connecting spring rod 29 is installed between the two sides of the connector 28 and the side surface of the water inlet pipe. A top connecting block 31 is installed on the upper surface of the water inlet pipe. The top connecting block 31 is connected to the bottom surface of the main frame 1. A pipe connection end 26 is installed on one side surface of the storage tank 10 for storing cleaning liquid. A telescopic pipe 16 is connected between the pipe connection end 26 and the spray box 5.

[0034] The immersion assembly is used to immerse the pretreatment plate 19 after the cleaning process, thereby creating a micro-etching effect on the surface of the pretreatment plate 19 to prepare for subsequent anti-oxidation treatment. After the cleaning assembly is completed, the pretreatment plate 19 is moved back to its original position by the limiting sleeve 25. Then, the two vertical clamping plates 18 are flipped to release the clamping effect on the pretreatment plate 19. Subsequently, the upper flipping plate 40 flips it again, and the two clamping bars 41 clamp the pretreatment plate 19 again. At this time, the two sliding side clamping plates 7 are also moved away by the small motor 21 to release the clamping effect on the pretreatment plate 19. At this time, the pretreatment plate 19 returns to the movable table. Above 8, the upper flip plate 40 flips and resets. Driven by a signal, the movable platform 8 moves the pretreatment plate 19 to one end of the sliding groove platform 61. The electric rotating shaft 45 drives the lower flip plate 44 and the pretreatment plate 19 above it to flip 180 degrees. Then, the two miniature telescopic rods 34 retract, causing the two clamping claws 36 to clamp the pretreatment plate 19 from both sides. Subsequently, the two clamping bars 41 release their clamping effect on the pretreatment plate 19, and the movable platform 8 restarts, causing the structure above it to move above the sliding groove platform 61, from one end to the other, for the lower part of the pretreatment plate 19. After lowering to make room, the internal hydraulic rod 32 drives the entire connecting platform 33 to descend, allowing the pretreatment plate 19 to enter the soaking tank 17 and be immersed in the soaking solution inside the soaking tank 17, thus completing the micro-etching process. After the soaking process is completed, the pretreatment plate 19 is returned to the upper surface of the upper flip plate 40 through the reverse operation of the previous process, and then transported back to the side surface of the limiting sleeve 25 by the upper flip plate 40. The limiting sleeve 25 drives the pretreatment plate 19 to reciprocate several times inside the chute, thereby vibrating and removing the soaking solution on its surface. After completion, the pretreatment plate 19 is returned to the top of the movable platform 8 for the operator to proceed. The water droplets are removed for subsequent processing. During the vibration process to remove water droplets, the droplets fall into the receiving frame 3 and are collected and flow through the receiving frame 3. Finally, they enter the bottom connecting box 47 through the drain on the upper surface of the receiving frame 3. The bottom motor 9 can be driven by the operator to rotate the steering box 48, thereby adjusting the rotation position of the steering box 48 and guiding the two different liquids through different paths. When rotating to one side, the water delivery block 49 on the side surface of the steering box 48 engages with the connector 28 on the upper part of the corresponding liquid storage tank 10, so that the water can enter the liquid storage tank 10 through the telescopic hose 30 for storage.

[0035] The micro-etching mechanism also includes a water-guiding component, which includes a sub-base plate 13 located on one side of the liquid tank bottom plate 12. The sub-base plate 13 is made of a high-strength, corrosion-resistant alloy material. A filter box 51 and a conveyor box 54 are mounted on the upper surface of the sub-base plate 13. The filter box 51 is a crucial component in the water-guiding mechanism for the initial purification of the treatment liquid. The filter box 51 contains multiple purification filter plates 52, which employ a multi-layer composite structure. Each filter plate has different filtration precision and function. The filter box 51 is connected to a storage tank for storing the cleaning liquid. The liquid tanks 10 are connected by a water supply pipe 58. The water supply pipe 58 is made of corrosion-resistant plastic with a smooth interior to reduce water flow resistance and ensure that the treated liquid can be quickly and stably transported from the filter box 51 to the storage tank 10. The filter box 51 and the transport box 54 are connected by a water supply connecting pipe 53. The transport box 54 has two partition plates 56 inside, which separate two hidden cavities. Each hidden cavity is equipped with an internal battery 57. The system utilizes high-performance lithium-ion batteries, offering advantages such as high energy density, long lifespan, and fast charging speed. The internal structure of the transmission box 54 also includes a water-powered rod 55, which is the core power component of the transmission box 54. The water-powered rod 55 is connected to the internal battery 57 via cables. The upper surface of the water supply connecting pipe 53 is also equipped with a power transmission cable 59, which is connected to the two internal batteries 57 via cables. The bottom surface of the soaking tank 17 is equipped with a rotating disc 37, which is made of wear-resistant and durable materials. Made of corrosive material, the bottom surface of the soaking tank 17 is equipped with a control motor 38. The output shaft end of the control motor 38 is connected to the bottom surface of the rotating disc 37. The power transmission cable 59 is connected to the control motor 38 via a cable. A side auxiliary box 39 is provided on one side surface of the soaking tank 17. An internal water pump 60 is provided inside the side auxiliary box 39. A connecting water supply pipe 58 is connected between the water inlet end of the internal water pump 60 and one end of the conveyor box 54. A water outlet branch pipe is provided on the upper surface of the side auxiliary box 39. The water outlet branch pipe is connected to the water outlet end of the internal water pump 60.

[0036] The water intake component is used to reuse the liquid stored in the two storage tanks 10. During use, before the cleaning solution and soaking solution enter the storage tank 10, they are filtered through multiple filled filter plates 27 to remove impurities. The filtered liquid accumulates inside the storage tank 10. Subsequently, after a certain period of use, the content of the soaking solution decreases. A small water pump inside the storage tank 10, which stores the cleaning solution, pumps the cleaning solution through a connecting water pipe 58 into the filter box 51, where it is filtered by multiple purification filter plates 52. This filters out the corrosion inhibitors and complexing agents beneficial to the soaking solution from the cleaning solution, resulting in a concentrated solution. Once the concentrated solution reaches a certain concentration, it is stored in the filter box 51 and... Inside the transport box 54, when the soaking solution needs to be filled, the operator starts the internal water pump 60 via a signal. The concentrated solution is drawn from inside the transport box 54 through the water pipe 58 and injected into the soaking tank 17 to improve the soaking effect. When the concentrated solution is transported, it drives the water-powered rod 55 to rotate. When the water-powered rod 55 rotates, a certain amount of electricity is generated through the generators at both ends of the rod and stored in the two internal batteries 57. The electricity is then transmitted to the control motor 38 through the power cable 59, thereby starting the control motor 38. When the control motor 38 starts, it drives the rotating disc 37 to rotate, thereby causing the soaking solution to flow and improving the soaking effect on the pretreatment plate 19.

[0037] The working principle of this invention is:

[0038] When the equipment is working, the cleaning process is carried out first. The pretreatment plate 19 is placed on the upper flip plate 40 by the staff, and the micro motor 42 is started to fix the clamping bar 41 initially. The movable table 8 slides along the sliding groove 61 and approaches the sliding table 2. The upper flip plate 40 flips and raises the pretreatment plate 19. The small electric shaft drives the vertical clamping plate 18 to initially clamp vertically. The clamping bar 41 is released and reset. The small motor 21 makes the bidirectional meshing rod 22 rotate, and the sliding side clamping plate 7 clamps precisely laterally. The servo motor 62 drives the limiting sleeve 25 to move in the chute. The bottom slider 23 slides along the bottom protrusion 4 to spray the cleaning liquid below the spray box 5. Because the vertical clamping plate 18 has an opening, it can be cleaned on both sides. After the spraying is finished, the servo motor 62 continues to drive the movement. The bottom slider 23 contacts the bottom protrusion 4 to make the pretreatment plate 19 vibrate, and the cleaning liquid is shaken off to the receiving frame 3.

[0039] Next is the soaking process. The limiting block 25 resets the pretreatment plate 19, the vertical clamping plate 18 is released, the upper flipping plate 40 flips again, the clamping bar 41 re-clamps, the movable platform 8 moves, the lower flipping plate 44 flips 180 degrees, the micro telescopic rod 34 retracts, and the clamping claw 36 clamps the pretreatment plate 19. The movable platform 8 moves to make room, and the internal hydraulic rod 32 drives it to descend. The pretreatment plate 19 enters the soaking tank 17 for micro-etching. After completion, the operation is reversed, and the pretreatment plate 19 returns to the upper flipping plate 40. The soaking liquid is shaken off through the reciprocating motion.

[0040] The water intake component enables liquid reuse. After being filtered by the filling filter plate 27, the liquid is stored. After a period of use, the cleaning solution is fed into the filter box 51 through the connecting water pipe 58. The purification filter plate 52 filters out the beneficial components to form a concentrated solution. The internal water pump 60 draws the concentrated solution and injects it into the soaking tank 17. The concentrated solution drives the water-powered rod 55 to rotate and generate electricity, which is stored in the internal battery 57. This electricity powers the control motor 38 and drives the rotating disc 37 to rotate, enhancing the soaking effect.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
