Description

Technical Field

[0001] The invention relates to the technical field of circuit board ink spraying, in particular to a circuit board solder mask ink spraying device. Background Art

[0002] When the circuit board is being processed, it needs to be sprayed with solder-resistant ink. The so-called solder-resistant ink is also called solder resist ink. Its main function is to protect and insulate the wires and components on the circuit board to prevent them from being damaged by environmental factors. At the same time, solder resist ink can also play a certain mechanical strengthening role, making the circuit board harder and more durable.

[0003] A Chinese patent application with announcement number CN221816452U proposes a circuit board insulating ink sprayer, including a sprayer box, support feet are provided on the left and right sides of the bottom of the sprayer box, an observation window is provided on the front side of the sprayer box, mounting holes are provided on the front and rear sides of the sprayer box, a movable arm is provided on the inner top wall of the sprayer box, a spray nozzle is provided at the bottom of the movable arm, support frames located outside the mounting holes are provided on the front and rear sides of the sprayer box, a conveying mechanism passing through the two mounting holes is provided between the inner sides of the two support frames, and an adjustment mechanism fixedly connected to the conveying mechanism is provided between the front and rear sides of the sprayer box, which can effectively facilitate users to adjust the conveying according to the size of the circuit board, effectively improve the applicability of the ink sprayer, and facilitate users to use it.

[0004] When spraying ink on circuit boards, the above device can adapt to the transportation needs of circuit boards of different sizes, but its transportation structure is still relatively simple. For example, in the actual spraying process of circuit boards, it is often necessary to spray them on both sides. When the above device performs a single transportation, it can only meet the spraying of the side of the circuit board facing the spraying device. For the other side, the circuit board that has been sprayed on one side needs to be turned over and re-transported to receive a second spraying. Correspondingly, a circuit board needs to go through two operations of picking up, placing, transporting and spraying, which has the problems of complicated procedures and relatively time-consuming. Therefore, a circuit board solder mask ink spraying equipment that can spray both sides of the circuit board in a single transportation is proposed to solve the above problems.

The drying assembly 6 includes a frame 61, which is fixedly connected to the bottom of the horizontal plate 5. A dryer body 62 is fixedly connected inside the frame 61. An air inlet 63 is provided on one side wall of the frame 61. A lower baffle 64 is provided on one side of the frame 61. The lower baffle 64 extends into the interior of the frame 61 and contacts with the inner cavity wall of the frame 61. A side baffle 65 is provided on one side of the air inlet 63.

[0036] In the actual operation process, firstly, the device is powered on. When working, the circuit board workpiece to be sprayed is conveyed on the conveyor 2. When the circuit board is conveyed to the bottom of the spray gun 48, the spray gun 48 can perform the spraying operation on the circuit board workpiece. During the spraying process, the second motor 45 drives the second threaded rod 44 to rotate after working, and the second threaded rod 44 drives the movable block 43 to move forward and backward. The movable block 43 drives the rectangular frame 46 to move, and the fourth electric push rod 493 pushes the auxiliary block 47 after working. It can be seen from the above connection relationship that through the above two operations, the spray gun 48 can be controlled to move forward, backward, left and right respectively, so as to adjust the position of the spray gun 48 to achieve the purpose of spraying each area; After the single-sided spraying operation is completed, the dryer body 62 first works to dry the paint surface on the circuit board to accelerate its forming and avoid the paint surface being damaged after the unformed paint surface contacts the conveyor 2 when the surface is subsequently turned over. Since the horizontal plate 5 is fixedly connected to one side of the auxiliary block 47, the above position adjustment operation of the spray gun 48 is repeated, and the position of the dryer body 62 can also be adjusted to achieve the operation of drying each area. The side baffle 65 and the lower baffle 64 can respectively block the air inlet 63 and the bottom opening of the frame 61, so as to prevent the paint from entering the frame 61 during the spraying process and causing pollution to the outside of the dryer body 62, which is beneficial to prolonging the service life of the dryer body 62. When the dryer body 62 needs to work, the sixth electric push rod 66 pushes the lower baffle 64 after working, and the lower baffle 64 moves toward one side of the frame 61 and leaves the contact plate 68. At this time, due to the elastic force of the spring 69, the contact plate 68 is also pushed away from the frame 61. At this time, the contact plate 68 drives the second push-pull plate 691 to flip during the movement of the contact plate 68. After the second push-pull plate 691 flips, it pulls the side baffle 65 downward. After the side baffle 65 moves downward, it gives up blocking the air inlet 63. Subsequently, when the dryer body 62 is working, external air can enter through the air inlet 63, and the hot air flow is discharged through the bottom opening of the frame 61. When the paint drying operation is completed, the third electric push rod 384 can push and pull the rectangular plate up and down after working, the rectangular plate drives the lifting plate 33 to move, the lifting plate 33 drives the mounting plate 32 to move, the mounting plate 32 drives the sleeve 34 to move, the sleeve 34 drives the first threaded rod 36 to move, the first threaded rod 36 drives the connecting frame 35 to move, the connecting frame 35 drives the supporting plate 38 to move up and down, the supporting plate 38 can lift the circuit board workpiece after rising, and similarly, when the circuit board is turned over after lifting, the supporting plate 38 can also be controlled to fall to re-place the circuit board on the conveyor 2; After the support plate 38 lifts the circuit board upward, the second electric push rod 398 works to push the control plate 391, and the control plate 391 moves and drives the first push-pull plate 393 to flip, and the first push-pull plate 393 flips and pulls the clamping block 392, and the clamping block 392 moves towards each other to clamp the circuit board to ensure the stability of the circuit board, and then the second electric push rod 398 works to push the moving plate 395, and the moving plate 395 drives the rack 396 to move, and the rack 396 drives the first gear 397 to rotate, and the first gear 397 drives the round rod 37 to rotate, and the round rod 37 drives the support plate 38 to rotate, so as to control the support plate 38 to rotate 180 degrees, and then the surface of the circuit board that has not been sprayed faces upward, and then repeat the above similar operations to move the circuit board downward and place it on the conveyor 2 After the bracket 38 is put on, the control support plate 38 moves upward until the clamping block 392 is higher than the circuit board, the first motor 399 works and drives the second gear 381 to rotate, the second gear 381 drives the third gear 382 to rotate, and the third gear 382 drives the sleeve 34 to rotate. After the sleeve 34 rotates, it prompts the first threaded rod 36 to move horizontally. At this time, the first threaded rod 36 drives the connecting frame 35 to move away from the circuit board, prompting the support plate 38 to move to one side of the circuit board, avoiding the support plate 38 from causing adverse effects on the subsequent spraying operation of the circuit board. Based on the above operations, the effect of changing the surface of the circuit board by spraying can be quickly completed, and during the changing process, the position where the circuit board is placed will not change, that is, it is still in the spraying area, and can be sprayed directly, which greatly guarantees the spraying efficiency and spraying quality.

[0037] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
