Description

Technical Field

[0001] This utility model relates to the field of circuit board spraying technology, and more specifically, it relates to a PCB circuit board solder resist spraying equipment. Background Technology

[0002] Solder resist coating is a protective layer applied to the surface of a circuit board, primarily used to protect the board from factors such as oxidation, corrosion, and contamination.

[0003] In the process of manufacturing circuit boards, a layer of solder resist ink is first applied to the surface of the circuit board. This ink is usually a highly elastic polymer organic material that can be cured at high temperatures and forms a protective layer with anti-corrosion and insulation properties after curing, preventing short circuits between wires.

[0004] However, during the spraying process, it was found that the components on each circuit board surface are different, and therefore the arrangement of the components on the circuit board surface is also inconsistent. This leads to the accumulation of solder resist ink on the circuit board at the angle between the components and the substrate, resulting in uneven thickness of the solder resist layer and affecting the performance of the PCB circuit board. To address this, a PCB circuit board solder resist spraying equipment is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PCB circuit board solder resist spraying equipment.

Detailed Implementation

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] Please see Figures 1-5 The present invention provides the following technical solution:

[0022] Example 1, see Figures 1-5A PCB circuit board solder resist spraying device includes a support platform 1, a support cover 2 on the top of the support platform 1, a drive motor 3 on one side of the support cover 2, a drive shaft 31 at the output end of the drive motor 3, a drive block 32 sleeved on the drive shaft 31, a drive plate 33 on the side wall of the drive block 32, a lifting motor 4 at the top of the drive plate 33, a lifting shaft 41 at the output end of the lifting motor 4, a lifting block 42 sleeved on the lifting shaft 41, a lifting plate 43 on the side wall of the lifting block 42, and a spray gun 5 on the side wall of the lifting plate 43 away from the lifting block 42.

[0023] The top of the support platform 1 is also equipped with a displacement motor 6. The output end of the displacement motor 6 is equipped with a displacement shaft 61. A displacement block 62 is sleeved on the displacement shaft 61. A displacement plate 63 is provided on the top of the displacement block 62. An adjustment component 7 is provided on the top of the displacement plate 63. Fixing components 8 are evenly arranged on the top of the adjustment component 7. A circuit board 9 is arranged between the fixing components 8.

[0024] Before spraying the circuit board 9, the drive motor 3 is started, which drives the drive shaft 31 to rotate. This allows the drive block 32 to drive the drive plate 33 to move synchronously in the axial direction M, so that the spray gun 5 is in a suitable spraying position, thereby achieving the purpose of adjusting the position of the spray gun 5.

[0025] On the other hand, the lifting motor 4 also starts, driving the lifting shaft 41 to rotate, so that the lifting block 42 drives the lifting plate 43 to move synchronously in the vertical direction, so that the spray gun 5 gets close to the surface of the circuit board 9 and reaches a suitable height, avoiding the spray gun 5 from spraying and splashing onto other parts of the circuit board 9.

[0026] At the same time, the displacement motor 6 is also started, driving the displacement shaft 61 to rotate, so that the displacement block 62 drives the displacement plate 63 to move in the radial N direction, so that the circuit board 9 is located below the spray gun 5, thereby facilitating subsequent precise spraying.

[0027] The function of the adjusting component 7 is to tilt and shake the coated circuit board 9 at an angle, so that the solder resist ink accumulated at the angle between the components and the substrate on the circuit board 9 flows out and spreads to other parts of the circuit board 9, mixing evenly with the solder resist ink in other parts. This ensures uniform coverage of the solder resist ink and avoids the accumulation of solder resist ink at the angle between the components and the substrate, which would lead to uneven thickness of the solder resist layer, thereby improving the performance of the PCB circuit board.

[0028] See Figures 1-5Furthermore, the output end of the drive motor 3 passes through the side wall of the support cover 2 and is connected to the drive shaft 31. The end of the drive shaft 31 away from the drive motor 3 is rotatably connected to the inner wall of the support cover 2. A fixing plate 21 is also provided inside the support cover 2. A drive slide rail 22 is symmetrically arranged on the side wall of the fixing plate 21. A drive slider 23 is slidably connected on the drive slide rail 22. The side wall of the drive plate 33 near the drive block 32 is connected to the side of the drive slider 23 away from the drive slide rail 22.

[0029] In the process of the drive block 32 driving the drive plate 33 to move, the drive slider 23 will also slide on the drive slide rail 22, thereby achieving the purpose of guidance.

[0030] See Figures 1-5 Furthermore, the side of the drive plate 33 is U-shaped. One end of the lifting shaft 41 passes through the side wall of the drive plate 33 and is connected to the output end of the lifting motor 4. The other end is rotatably connected to the other side wall of the drive plate 33. A lifting slide rail 44 is also symmetrically arranged on the side wall of the drive plate 33 away from the drive block 32. A lifting slider 45 is slidably connected on the lifting slide rail 44. The side wall of the lifting plate 43 away from the spray gun 5 is connected to the side of the lifting slider 45 away from the lifting slide rail 44.

[0031] During the process of the lifting block 42 driving the lifting plate 43 to rise and fall, the lifting slider 45 will also slide on the lifting rail 44, thereby achieving the purpose of guidance.

[0032] See Figures 1-5 Furthermore, a displacement slide rail 11 is symmetrically arranged on the top of the support platform 1, and a displacement slider 12 is slidably connected on the displacement slide rail 11. The top of the displacement slider 12 is connected to the bottom of the displacement plate 63.

[0033] In the process of displacement block 62 driving displacement plate 63 to move, displacement slider 12 will also slide on displacement rail 11, thereby achieving the purpose of guidance.

[0034] See Figures 1-5Furthermore, the adjusting component 7 includes a first adjusting frame 71, an adjusting ball 72 rotatably connected to one end of the first adjusting frame 71, a second adjusting frame 73 rotatably connected to the end of the adjusting ball 72 away from the first adjusting frame 71, an adjusting plate 74 disposed at the end of the second adjusting frame 73 away from the adjusting ball 72, and adjusting cylinders 75 evenly disposed below the adjusting plate 74; the first adjusting frame 71 and the second adjusting frame 73 have the same structural shape and are disposed opposite to each other, one end of the first adjusting frame 71 is cylindrical and the other end is arc-shaped, the adjusting ball 72 is located between the arc-shaped ends of the first adjusting frame 71 and the second adjusting frame 73, the adjusting plate 74 is cross-shaped, one end of the adjusting cylinder 75 is connected to the top of the displacement plate 63, and the other end is rotatably connected to the bottom of the adjusting plate 74, and the fixing component 8 is located at the corresponding top of the adjusting plate 74.

[0035] See Figures 1-5 Furthermore, the fixing component 8 includes a fixing cylinder 81 and a fixing block 82 disposed at the extension end of the fixing cylinder 81; the circuit board 9 is located between the fixing blocks 82.

[0036] Before spraying the circuit board 9, the circuit board 9 is placed on the side wall of the four fixed cylinders 81. Then, all four fixed cylinders 81 are activated, pulling the fixed blocks 82 back, so that the four fixed blocks 82 simultaneously clamp and fix the four sides of the circuit board 9, thereby achieving the purpose of fixing the circuit board 9.

[0037] After the circuit board 9 is coated, one of the adjusting cylinders 75 is activated, pushing one end of the adjusting plate 74 upward. At the same time, another adjusting cylinder 75, located opposite to one of the adjusting cylinders 75, is also activated, its telescopic end pulling the other end of the adjusting plate 74 downward, causing the circuit board 9 to change from a horizontal state to an inclined state. During this process, the adjusting plate 74 also drives the second adjusting frame 73 and the adjusting ball 72 to rotate in the axial direction M around the arc end of the first adjusting frame 71. This causes the solder resist ink that has accumulated at the angle between the components and the substrate on the circuit board 9 to flow out and spread to other positions on the circuit board 9, mixing evenly with the solder resist ink in other positions. This ensures uniform coverage of the solder resist ink and avoids the accumulation of solder resist ink at the angle between the components and the substrate, which would lead to uneven thickness of the solder resist layer, thereby improving the performance of the PCB circuit board.

[0038] If angle adjustments are required in other directions, the same principle applies. It should be noted that when adjusting the angle in the radial N direction, the adjusting plate 74 drives the second adjusting frame 73 to rotate along the outer wall of the adjusting ball 72.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
