Description

Technical Field

[0001] The present invention relates to the technical field of circuit board ink cleaning, and particularly to an ink cleaning device for printed circuit boards. Background Art

[0002] The ink cleaning of printed circuit boards mainly involves cleaning the ink residues on the circuit boards. During the production process of printed circuit boards, ink is often used for marking, insulation, or protection of circuits. However, after fulfilling its mission, these ink residues may have an adverse impact on the performance and reliability of the circuit boards.

[0003] Chinese Patent Publication No. CN116567948A discloses an ink cleaning device and method for printed circuit boards. The ink cleaning device for printed circuit boards includes a cleaning component, a transfer ball, and a fluorescence detection lamp. A finished product station and a defective product station are arranged around the transfer ball. When cleaning the solder resist ink, the cleaning component sprays an ink developer onto the surface of the circuit board, and the transfer ball transports the circuit board from the cleaning station to the detection station, the finished product station, or the defective product station. Since the transfer ball can rotate in multiple directions, it can transport the circuit board by rotation without generating a linear displacement on its own, thereby shortening the transmission path and sorting circuit boards with different cleaning effects. The ink cleaning method for printed circuit boards includes the following steps: S1 rinsing → S2 detection → S3 sorting. This application has the effect of detecting the cleaning effect of the circuit board and sorting the circuit boards with residual ink; however, the above patent document still has the following defects in the implementation process:

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, by providing a conveying mechanism, a guiding mechanism and a rotating clamping mechanism, the printed circuit board can be cleaned by a combination of chemistry and physics. During the cleaning process, the printed circuit board can be flipped, vibrated and rinsed, which can promote the ink cleaning agent to more effectively penetrate into the tiny gaps and pores on the surface of the circuit board, and can more thoroughly remove the ink residues attached to the circuit board, change the flow direction of the ink cleaning agent, circulate the ink cleaning agent, enhance the contact and reaction between the ink cleaning agent and the ink on the printed circuit board, so that the ink on the printed circuit board can be effectively removed.

[0018] 2. In the present invention, by providing an aeration mechanism, the circular hole block one and the circular hole block two can effectively disperse and inject air into the ink cleaning agent and water. The air can increase the oxygen content in the cleaning agent, which helps to accelerate the rate of certain chemical reactions in the cleaning agent, thereby improving the cleaning efficiency. The injection of air will generate bubbles. During the process of these bubbles rising and bursting in the cleaning agent, they will drive the diffusion of the cleaning agent on the surface of the circuit board, helping the cleaning agent to cover the surface of the circuit board more evenly, thereby improving the uniformity and thoroughness of cleaning.

[0019] 3. In the present invention, by providing an air venting mechanism, a heating mechanism and a rotating clamping mechanism, the air can have sufficient time to be heated through the heating pipe, enabling the printed circuit board to be dried while being flipped. Drying while being flipped can ensure that both sides of the circuit board are evenly heated to avoid deformation of the printed circuit board, thereby accelerating the drying speed. The hot air or drying gas can more fully contact all parts of the circuit board, ensuring that all areas on the circuit board can reach an appropriate dryness level for those corners and gaps that are difficult to directly blow to, and avoiding corrosion and oxidation problems caused by local residual moisture or cleaning agent.

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0034] Example 1, as shown in Figure 1 and Figure 2 A printing circuit board ink cleaning device includes an outer shell 1. Support legs 2 are fixedly connected to the four corners of the lower end of the outer shell 1. A control box 3 is fixedly connected to the left end of the outer shell 1. A cleaning component 4 is jointly arranged on the inner surface of the outer shell 1 and the left end of the outer shell 1. A drying component 5 is jointly arranged on the rear part of the upper end of the outer shell 1 and the inner surface of the outer shell 1.

[0035] In the process of implementing this embodiment, the printed circuit board is placed in the cleaning component 4. At this time, by operating the control box 3, the cleaning component 4 starts to operate, driving the printed circuit board to move backward in the inner cavity of the housing 1. Subsequently, the printed circuit board first enters the ink cleaning agent, where it can be soaked and then flipped and vibrated up and down to clean the ink on the printed circuit board. Then, during the backward movement, the printed circuit board will move away from the ink cleaning agent, and the ink cleaning agent will flow to clean the printed circuit board again. Finally, the printed circuit board is cleaned by soaking, flipping, and aerating it in water. After cleaning, the printed circuit board is dried by the drying component 5.

[0036] The control box 3 mentioned above is a mature control technology means and device in the prior art. In this solution, the functions that can be controlled by it are utilized, and the internal structure, principle, and connection method are not elaborated further.

[0037] Specifically, in order to clean the printed circuit board in a combined chemical and physical manner, refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 In this embodiment, the cleaning component 4 includes a cleaning frame one 41 fixedly connected to the inner surface of the housing 1. A cleaning frame two 42 is fixedly connected to the inner surface of the housing 1 directly behind the cleaning frame one 41. A conveying mechanism 43 is arranged on the inner surface of the housing 1. A guiding mechanism 44 is arranged on the upper part of the inner surface of the housing 1. A rotating clamping mechanism 45 is jointly arranged on the inner surfaces of the guiding mechanism 44, the cleaning frame one 41, and the cleaning frame two 42. An aeration mechanism 46 is jointly arranged on the lower parts of the inner surfaces of the cleaning frame one 41 and the cleaning frame two 42 and the left end of the housing 1.

[0038] Furthermore, refer to Figure 3 and Figure 4 In this embodiment, the conveying mechanism 43 includes two rotating rods 431 rotatably connected to the inner surface of the housing 1. A conveyor belt 432 is jointly wound around the outer surfaces of the two rotating rods 431 symmetrically from left to right. The lower parts of the mutually approaching ends of the two conveyor belts 432 are jointly fixedly connected with a fixing plate 433. A rectangular hole 434 is opened at the upper end of the fixing plate 433. A servo motor 435 fixedly connected to the left end of the housing 1 is fixedly connected to the left end of the front rotating rod 431.

[0039] Furthermore, refer to Figure 3 、 Figure 6 、 Figure 7 and Figure 9, in this embodiment, the rotation clamping mechanism 45 includes two round rods 451 rotatably connected to the inner surface of the fixing plate 433. Fixed blocks 452 are fixedly connected to one ends of the two round rods 451 close to each other. Spring telescopic rods 453 are fixedly connected to the front and rear sides symmetrically at one ends of the two fixed blocks 452 close to each other. One ends of the spring telescopic rods 453 on the same side are fixedly connected to a clamping block 454 together. Gears 456 are fixedly connected to one ends of the two round rods 451 far from each other. First racks 457 meshing with the gears 456 are fixedly connected to the left and right sides symmetrically on the inner surface of the first cleaning frame 41. Second racks 4511 meshing with the gears 456 are fixedly connected to the left and right sides symmetrically on the inner surface of the second cleaning frame 42. Third racks 4512 meshing with the gears 456 are fixedly connected to the left and right sides symmetrically on the inner surface of the housing 1.

[0040] Further, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , in this embodiment, the guiding mechanism 44 includes a guiding plate 441 fixedly connected to the middle side of the upper part of the inner surface of the housing 1. A rectangular rod 446 is slidably connected to the inner surface of the rectangular hole 434. A concave block 442 is fixedly connected to the upper end of the rectangular rod 446. A concave plate 445 is fixedly connected to the lower end of the rectangular rod 446. A roller 443 closely attached to the lower end of the guiding plate 441 is rotatably connected to the inner surface of the concave block 442. A first return spring 444 is sleeved on the outer surface of the rectangular rod 446. The two ends of the first return spring 444 are fixedly connected to the upper end of the fixing plate 433 and the lower end of the concave block 442 respectively.

[0041] During the implementation process, the printed circuit board is placed in the two clamping blocks 454, so that the printed circuit board can be clamped in the clamping blocks 454 under the action of the spring telescopic rod 453. Subsequently, the output end of the servo motor 435 drives the rotating rod 431 located at the front to rotate through a coupling. Under the action of the winding connection, the conveyor belt 432 moves backward, driving the rectangular rod 446 on the fixed plate 433 to move backward. Since the roller 443 on the rectangular rod 446 is in close contact with the guide plate 441, the roller 443 is pushed by the guide and extrusion of the guide plate 441 to move the rectangular rod 446 downward on the inner surface of the rectangular hole 434, so that the first reset spring 444 is in a compressed state, and the printed circuit board is pushed into the ink cleaning agent inside the first cleaning frame 41, so that the printed circuit board can be immersed in the ink cleaning agent. During the process of continuing to move backward, first, the gear 456 meshes with the first rack 457, driving the printed circuit board on the clamping block 454 to flip in the ink cleaning agent. When the roller 443 moves to the wavy section of the guide plate 441, at this time, the printed circuit board moves up and down under the compression reaction force of the first reset spring 444, so that the printed circuit board can vibrate in the ink cleaning agent. The vibration and flipping actions can promote the ink cleaning agent to more effectively penetrate into the tiny gaps and pores on the surface of the circuit board, and can more thoroughly remove the ink residues, solder flux residues, dust and other impurities attached to the circuit board, ensuring that the surface of the circuit board is cleaner.

[0042] The material of the conveyor belt 432 mentioned above is a hard material in the prior art.

[0043] The servo motor 435 mentioned above is a mature technical means in the prior art. In this solution, only its functions of controlling the rotation speed, rotation circle number, forward and reverse rotation, and starting and stopping at any time are borrowed. The structure and working principle of it will not be elaborated further in this solution.

[0044] Further, referring to Figure 7 and Figure 8 , in this embodiment, a water pump 458 is fixedly installed at the lower part of the inner surface of the first cleaning frame 41. The lower end of the water pump 458 is fixedly connected to a connecting pipe 459 fixedly connected to the inner surface of the first cleaning frame 41. A spiral ring 4510 is fixedly connected to the inner surface of the connecting pipe 459.

[0045] During the implementation process, after the printed circuit board vibrates, the roller 443 will move upward along the guide plate 441 under the compression reaction force of the return spring 444, so that the printed circuit board can leave the ink cleaning agent. Subsequently, the roller 443 will move to the stable section of the guide plate 441. At this time, the water pump 458 is started to pump the ink cleaning agent in the cleaning frame 41 into the connecting pipe 459. Under the action of the spiral ring 4510, the flow direction of the ink cleaning agent is changed, so that the ink cleaning agent can wash the outer surface of the printed circuit board during the movement process, change the flow direction of the ink cleaning agent, circulate the ink cleaning agent, enhance the contact and reaction between the ink cleaning agent and the ink on the printed circuit board, and can more flexibly wash different areas of the circuit board surface to ensure the uniformity and thoroughness of the cleaning.

[0046] Secondly, after the chemical cleaning of the printed circuit board, it can enter the water inside the cleaning frame 42 under the action of the guide plate 441. At the same time, under the meshing action of the gear 456 and the rack 4511, the printed circuit board is driven to turn in the water, and the ink on the outer surface of the printed circuit board can be cleaned again, and at the same time, the cleaning agent remaining on the printed circuit board can be removed.

[0047] Further, referring to Figure 3 、 Figure 10 and Figure 11 In this embodiment, the aeration mechanism 46 includes an air pump 461 fixedly connected to the rear part of the left end of the housing 1. A plurality of cylinders 463 are linearly distributed and fixedly connected to the inner surfaces of the cleaning frame 41 and the cleaning frame 42. A round hole block 464 is fixedly connected to the upper ends of the plurality of cylinders 463. A connecting block 465 is fixedly connected to the inner surfaces of the plurality of cylinders 463. A spherical rod 467 is slidably connected through the middle of the lower ends of the plurality of connecting blocks 465 and extends to the upper ends of the round hole blocks 464. A round hole block 466 is fixedly connected to the upper ends of the plurality of spherical rods 467. A return spring 468 is sleeved on the outer surfaces of the plurality of spherical rods 467. The two ends of the plurality of return springs 468 are respectively fixedly connected to the outer surface of the ball on the spherical rod 467 and the lower end of the connecting block 465. A first ventilation pipe 462 fixedly connected to the lower end of the air pump 461 is fixedly connected to the common inner surfaces of the plurality of cylinders 463.

[0048] As described above, when the printed circuit board continues to be cleaned by chemical and physical cleaning methods, the air pump 461 can be started to extract air and inflate it into the first air pipe 462. At this time, the air will push the spherical rod 467 upward and compress the second return spring 468, causing the circular hole block two 466 on the spherical rod 467 to move away from the circular hole block one 464. After the sphere on the spherical rod 467 moves away from the inner surface of the cylinder 463, the air will enter the inner cavity of the cylinder 463 and be injected into the ink cleaning agent and water through the circular holes on the circular hole block one 464 and the circular hole block two 466. Injecting air can increase the oxygen content in the cleaning agent, which helps to accelerate the rate of certain chemical reactions in the cleaning agent, thereby improving the cleaning efficiency. The injection of air will generate bubbles, and during the process of these bubbles rising and bursting in the cleaning agent, it will drive the diffusion of the cleaning agent on the surface of the circuit board. This diffusion effect helps the cleaning agent to cover the surface of the circuit board more evenly, thereby improving the uniformity and thoroughness of the cleaning.

[0049] The injection volume mentioned above can be adjusted correspondingly according to the actual cleaning situation, as long as it can meet the effective cleaning of the printed circuit board.

[0050] The circular holes on the circular hole block one 464 and the circular hole block two 466 are staggeredly distributed in terms of their positional relationship.

[0051] Embodiment 2: On the basis of Embodiment 1, this embodiment adds a drying component 5 for drying the printed circuit board after cleaning, so as to achieve the purpose of drying the printed circuit board after cleaning.

[0052] Specifically, in order to dry the printed circuit board after cleaning, refer to Figure 3 and Figure 12 , in this embodiment, the drying component 5 includes a hollow block 51 fixedly connected to the rear part of the upper end of the outer shell 1, a ventilation mechanism 52 is arranged on the inner surface of the outer shell 1, and a heating mechanism 53 is arranged in the inner cavity of the hollow block 51.

[0053] Furthermore, refer to Figure 3 and Figure 12 , in this embodiment, the ventilation mechanism 52 includes a second air pipe 521 that penetrates the inner surface of the first air pipe 462 and extends to the upper part of the inner surface of the hollow block 51 and is fixedly connected. A solenoid valve 522 is fixedly connected to the intersection of the outer surface of the second air pipe 521 and the outer surface of the first air pipe 462. The left and right sides of the inner surface of the hollow block 51 are symmetrically penetrated and extended to the inner surface of the outer shell 1 and fixedly connected with third air pipes 523. A number of nozzles 524 are fixedly connected to the side of the outer surfaces of the two third air pipes 523 close to each other at equal linear distances.

[0054] Furthermore, refer to Figure 3 and Figure 12, in this embodiment, the heating mechanism 53 includes a partition plate 531 fixedly connected to the inner surface of the hollow block 51. A heating pipe 532 is fixedly installed on the inner surface of the hollow block 51 below the partition plate 531. The upper end of the partition plate 531 is fixedly connected to a circular hole T-shaped plate 533 fixedly connected to the inner surface of the hollow block 51. The upper end of the partition plate 531 is fixedly connected with blocking plates 534 that are symmetrically distributed left and right in a linear staggered manner and are fixedly connected to the inner surface of the hollow block 51 and the rear end of the circular hole T-shaped plate 533.

[0055] During the implementation process, the cleaned printed circuit board will move away from the water inside the cleaning frame two 42, and during the backward movement, under the action of the solenoid valve 522, the air extracted by the air pump 461 will enter the hollow block 51 through the second ventilation pipe 521. Under the action of the circular hole T-shaped plate 533, the air is divided into two parts and enters the symmetrically distributed left and right blocking plates 534. Since the symmetrically distributed left and right blocking plates 534 are arranged in an equidistant staggered manner, the air moves in an S-shaped route under the action of the blocking plates 534. Under the action of the heating pipe 532, the temperature of the air increases. The heated air dries the printed circuit board through the nozzle 524 on the third ventilation pipe 523. At the same time, under the meshing action of the gear 456 and the third rack 4512, the printed circuit board can be dried while being flipped. Drying while flipping can ensure that both sides of the circuit board are evenly heated, avoid deformation of the printed circuit board, thereby accelerating the drying speed, and the hot air or drying gas can more fully contact all parts of the circuit board, reaching those corners and gaps that are difficult to directly blow to, ensuring that all areas on the circuit board can reach an appropriate drying degree, and avoiding corrosion and oxidation problems caused by local residual moisture or cleaning agent.

[0056] The solenoid valve 522 mentioned above is a mature control technology means and device in the prior art. In this solution, it is used to control the flow direction of gas, and its internal structure, principle, and connection method will not be elaborated.

[0057] The heating pipe 532 mentioned above is a mature heating technology means and device in the prior art. In this solution, it is used for its heating function, and its internal structure, principle, and connection method will not be elaborated.

[0058] There is a certain frictional force when the round rod 451 rotates with the concave plate 445, that is, it satisfies that after the gear 456 disengages from the first rack 457, the second rack 4511, and the third rack 4512, the round rod 451 will not rotate.

[0059] Workflow: During use, through the combined action of the rotation clamping mechanism 45, the conveying mechanism 43, and the guiding mechanism 44, the printed circuit board is driven to move backward in the inner cavity of the housing 1, and during the movement, the printed circuit board is soaked, and after soaking, it is flipped and vibrated up and down to clean the ink on the printed circuit board. The printed circuit board is cleaned by placing it in water for soaking and flipping, and during the cleaning process, the printed circuit board can also be assisted in cleaning by the aeration mechanism 46. After the printed circuit board is cleaned, it is dried by the ventilation mechanism 52 and the heating mechanism 53, and during the drying process, it is flipped and dried by the rotation clamping mechanism 45.
