Description

Technical Field

[0001] The invention relates to a processing device, in particular to an anti-oxidation processing device for a PCB board, and belongs to the technical field of anti-oxidation processing for a PCB board. Background Art

[0002] During the production, storage and use of electronic products, copper foil and other metals on PCB boards are easily affected by factors such as air humidity, temperature changes and chemical corrosion, which can cause oxidation. Once the copper foil is oxidized, the circuit performance will deteriorate or even fail. Anti-oxidation treatment can effectively extend the service life of PCB boards. This is mainly because anti-oxidation treatment can reduce the oxidation rate of copper foil and other metals, thereby slowing down the performance degradation process of the circuit board. This is of great significance for improving the durability of electronic products and reducing maintenance costs.

[0003] In the prior art, in order to perform anti-oxidation treatment on PCB boards, the PCB boards are often placed in chemical solutions for immersion treatment. These solutions usually contain chemical substances that can react with metal oxides, thereby effectively removing the formed oxide layer and forming a protective film on the metal surface to prevent further oxidation.

[0004] A known Chinese authorized patent (Announcement No.: CN221058530U) discloses an anti-oxidation treatment device for the surface of an LED printed circuit board, which places the LED printed circuit board to be treated in a placement frame, and then the placement frame drives the LED printed circuit board downward to immerse it in a treatment liquid. After the treatment is completed, the placement frame is moved above the device body, and then the circuit board is dried. During the drying process, an air dryer is started, and under the action of the air dryer, the air drying of the LED printed circuit board is accelerated;

[0005] The invention realizes the anti-oxidation treatment and air-drying of the circuit board through the lifting anti-oxidation treatment device and the air-drying mechanism. However, in the existing treatment process, the air-dryer is arranged on one side of the treatment device. This design has certain limitations. Specifically, since the air-dryer blows air to the circuit board from only one side, the air-drying effect is not ideal, and the moisture on the surface of the circuit board cannot evaporate quickly and evenly, so it is difficult to achieve the purpose of rapid air-drying. Therefore, a PCB board anti-oxidation treatment device is proposed. Summary of the invention

DETAILED DESCRIPTION

[0034] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0035] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] In the prior art, the air dryer is arranged on one side of the processing device. This design has certain limitations. Specifically, since the air dryer only blows air to the circuit board from one side, the air drying effect is not ideal, and the moisture on the surface of the circuit board cannot evaporate quickly and evenly, making it difficult to achieve the purpose of rapid air drying.

[0037] like Figure 1-Figure 8 As shown, an embodiment of the present invention provides an anti-oxidation treatment device for a PCB board, comprising a base 31, a support frame 23 is installed on the upper surface of the base 31, and an air-drying component 101 is installed on the support frame 23. The air-drying component 101 is used to achieve rapid air drying of the PCB board. During air drying, the PCB board can be blown from both sides at the same time, so that the moisture on the surface of the PCB board can be evaporated quickly and evenly, thereby achieving the purpose of rapid air drying;

[0038] The air drying assembly 101 includes a driving motor 11, a mounting plate 12, a driving gear 13, an axial flow fan 14, an air guide cover 15, a central air duct 16, a side air duct 17, a connecting frame 19, a rotating disk 20 and a driving gear ring 21;

[0039] A first electric telescopic rod 24 is installed on the upper surface of the turntable 20. The telescopic shaft of the first electric telescopic rod 24 is fixedly connected to the upper surface of the connecting frame 19. The connecting frame 19 is installed on the upper surface of the air guide cover 15. The height position of the connecting frame 19 can be adjusted by the first electric telescopic rod 24. When the PCB board needs to be air-dried, the first electric telescopic rod 24 pushes the connecting frame 19 to move downward.

[0040] The axial flow fan 14 is installed at the center of the upper surface of the air guide cover 15 and is connected to the air guide cover 15. The central air duct 16 is installed at the center of the lower surface of the air guide cover 15. The side air duct 17 is installed at the lower surface of the air guide cover 15 and is distributed in a ring shape. The inner wall of the side air duct 17 and the outer wall of the central air duct 16 are both provided with air holes 18. When air drying, air flows out from the air holes 18 on the side air duct 17 and the central air duct 16 respectively. The directions of the two air flows are opposite, and air is blown from both sides of the PCB board at the same time, thereby achieving rapid air drying;

[0041] When the axial flow fan 14 is working, the airflow enters the air guide cover 15, then flows from the air guide cover 15 into the side air duct 17 and the central air duct 16 respectively, and finally blows out from the air hole 18;

[0042] The driving motor 11 is fixedly connected to the upper surface of the support frame 23 through the mounting plate 12, the driving gear 13 is fixedly connected to the output shaft of the driving motor 11, the turntable 20 is rotatably connected to the inside of the support frame 23, the driving ring gear 21 is fixedly connected to the upper part of the outer wall of the turntable 20, the outer wall of the driving gear 13 is meshedly connected to the outer wall of the driving ring gear 21, the driving motor 11 drives the driving gear 13 to rotate, the driving gear 13 drives the driving ring gear 21 to rotate through the teeth, the driving ring gear 21 drives the turntable 20 to rotate, the turntable 20 drives the connecting frame 19 when rotating, the connecting frame 19 drives the air guide cover 15, and then the central air duct 16 and the side air duct 17 can be rotated, so that the airflow can evenly contact the two sides of the PCB board, and the PCB board can be quickly dried.

[0043] In one embodiment, two guide columns 22 are symmetrically fixedly connected to the upper surface of the connecting frame 19, and the top ends of the guide columns 22 pass through the upper surface of the turntable 20 and are slidably connected to the turntable 20. The guide columns 22 can protect the first electric telescopic rod 24. When the driving motor 11 drives the turntable 20 to rotate, the turntable 20 drives the connecting frame 19 to rotate through the guide columns 22, thereby protecting the first electric telescopic rod 24 to prevent the first electric telescopic rod 24 from being damaged by excessive force. At the same time, when the first electric telescopic rod 24 pushes the connecting frame 19 downward, the guide columns 22 can play a guiding role so that the connecting frame 19 can be lifted and lowered vertically.

[0044] In one embodiment, the central air duct 16 and the side air duct 17 are both connected to the air guide cover 15, and the side air duct 17 is arc-shaped. When the axial flow fan 14 is working, the airflow enters the air guide cover 15, and then flows from the air guide cover 15 into the central air duct 16 and the side air duct 17 respectively, and is blown out from the air hole 18, thereby achieving an air-drying action.

[0045] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a PCB board anti-oxidation treatment device and solves the problems through the above technical solutions:

[0046] When the PCB board is air-dried, the connecting frame 19 is pushed by the first electric telescopic rod 24, and the connecting frame 19 drives the air guide cover 15 to move downward. Since the central air duct 16 and the side air duct 17 are respectively arranged below the air guide cover 15, the central air duct 16 can be moved to the inside of the placement basket 36, and the side air duct 17 can be moved to the outside of the placement basket 36. When the axial flow fan 14 is working, the air flow enters the air guide cover 15, and then flows from the air guide cover 15 into the central air duct 16 and the side air duct 17 respectively, and is blown out from the air hole 18. The directions of the air flow are relative, and air is blown from both sides of the PCB board at the same time, so that the moisture on the surface of the PCB board can be evaporated quickly and evenly, thereby achieving the purpose of rapid air drying.

[0047] In one embodiment, an oxidation treatment assembly 301 is mounted on the upper surface of the base 31, and the oxidation treatment assembly 301 includes a treatment barrel 32, two guide rails 33, two connecting plates 34, a placement basket 36, a support plate 39 and two limiting protrusions 40;

[0048] The processing barrel 32 is installed on the upper surface of the base 31. The interior of the processing barrel 32 is provided with an anti-oxidation treatment liquid. The placement basket 36 is located inside the processing barrel 32. The placement basket 36 is used to load the PCB board. When the PCB board is loaded, the PCB board is vertically placed inside the placement basket 36.

[0049] Four limiting sockets 37 are symmetrically fixedly connected to the top of the inner side wall of the placement basket 36, and four limiting plugs 38 are symmetrically fixedly connected to the bottom of the inner side wall of the placement basket 36. Through the cooperation of the limiting sockets 37 and the limiting plugs 38, multiple placement baskets 36 can be docked to perform anti-oxidation treatment on multiple PCB boards at the same time according to the use requirements, while ensuring the stability of the placement basket 36;

[0050] The lower surface of the placement basket 36 is attached to the upper surface of the support plate 39. The upper surface of the support plate 39 is provided with a slot corresponding to the limit plug 38. The placement basket 36 can be supported by the support plate 39. The support plate 39 is liftable, so that the height position of the placement basket 36 can be adjusted according to the use requirements. The placement basket 36 at the bottom is plugged into the surface of the support plate 39 through the limit plug 38.

[0051] The two connecting plates 34 are symmetrically fixedly connected to the outer wall of the support plate 39, and the two limiting protrusions 40 are symmetrically fixedly connected to the outer wall of the support plate 39. The ends of the two connecting plates 34 are installed with second electric telescopic rods 35. The two second electric telescopic rods 35 are symmetrically installed on the upper surface of the base 31. The connecting plates 34 are pushed by the second electric telescopic rods 35, and the connecting plates 34 drive the support plate 39 to move upward. During the movement, the support plate 39 drives the placement basket 36, and the position of the placement basket 36 can be adjusted.

[0052] In one embodiment, two guide rails 33 are symmetrically installed on the inner wall of the processing barrel 32, and the limiting protrusion 40 is slidably connected to the inner wall of the guide rail 33. Through the cooperation of the guide rail 33 and the limiting protrusion 40, it can play a role of limiting guidance, so that the support plate 39 can be lifted and lowered vertically.

[0053] In one embodiment, the processing barrel 32 is coaxially arranged with the placement basket 36, and the air guide cover 15 is coaxially arranged with the placement basket 36. Therefore, when the PCB board is air-dried, the central air duct 16 is located inside the placement basket 36, and the side air duct 17 is located outside the placement basket 36.

[0054] In one embodiment, the shape of the limiting socket 37 is adapted to the shape of the limiting pin 38 , and when two or more placement baskets 36 are arranged inside the processing barrel 32 , the placement baskets 36 can be connected through the corresponding limiting sockets 37 and limiting pins 38 .

[0055] When the present invention is working, an anti-oxidation treatment liquid is added to the interior of the treatment barrel 32, the PCB board to be treated is vertically placed in the placement basket 36, the second electric telescopic rod 35 is controlled to push the connecting plate 34 upward, and the connecting plate 34 drives the support plate 39 to move upward, so that the support plate 39 is moved out of the treatment barrel 32, and then the placement basket 36 is installed on the support plate 39, one or more placement baskets 36 are selected and placed according to actual conditions, and then the second electric telescopic rod 35 is controlled to reset, and the placement basket 36 is moved into the treatment barrel 32, and the PCB board is immersed in the treatment liquid. When the anti-oxidation treatment of the PCB board is completed, the second electric telescopic rod 35 pushes the support plate 39 upward to move the placement basket 36 out of the treatment barrel 32, and then the first electric telescopic rod is controlled to reset. The rod 24 is extended, and the first electric telescopic rod 24 pushes the connecting frame 19 to move downward, and the connecting frame 19 drives the air guide cover 15 to move downward, moving the central air duct 16 to the inside of the placement basket 36, and moving the side air duct 17 to the outside of the placement basket 36, and controlling the axial flow fan 14 to work. At this time, the airflow enters the air guide cover 15, and then flows from the air guide cover 15 into the central air duct 16 and the side air duct 17 respectively, and is blown out from the air hole 18. The airflows in opposite directions blow air on both sides of the PCB board at the same time, so that the moisture on the surface of the PCB board can be evaporated quickly and evenly. After air drying, the first electric telescopic rod 24 is reset, and the air drying component 101 is away from the placement basket 36. At this time, the air-dried PCB board in the placement basket 36 can be taken out.

[0056] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
