Description

Technical Field

[0001] This utility model relates to the field of filter manufacturing and processing technology, specifically to a clamping and reversing structure for surface treatment of filter anti-interference circuit boards. Background Technology

[0002] In the manufacturing process of filter anti-interference circuit boards, surface treatment is a crucial step, encompassing multiple processes such as plating, anti-oxidation spraying, and impurity cleaning. Due to the precise component layout on the circuit board surface and the extremely high requirements for structural integrity in anti-interference performance, a special clamping device is needed to stably fix the circuit board during surface treatment. At the same time, according to the needs of different process steps, the horizontal position of the circuit board can be adjusted, the tilting and reversing at different angles can be performed, and the front and back sides can be flipped to ensure the uniformity and comprehensiveness of surface treatment, and to avoid problems such as circuit board damage and substandard processing quality caused by unstable clamping or insufficient reversing accuracy.

[0003] Existing filter anti-interference circuit board surface treatment equipment uses unidirectional positional movement, which makes it difficult to adapt to the needs of different sized processing stations through flexible translation adjustment. Furthermore, jamming and offset are prone to occur during translation, affecting processing accuracy. In addition, the single hinge-type flip structure has a limited range of adjustment angles, making it impossible to achieve multi-angle precise positioning according to the special requirements of surface treatment processes. Moreover, the lack of a stable auxiliary support structure makes the circuit board prone to shaking after angle adjustment. Summary of the Invention

[0010] This invention provides a clamping and reversing structure for surface treatment of a filter anti-interference circuit board. Compared with the prior art, it has the following advantages: By setting up a translation unit, the first air pump drives the first air rod to extend and retract, causing the slide plate to slide stably along the first slide rail, achieving flexible translation in the horizontal direction. This, in turn, drives the adjustment plate to adjust forward and backward. By setting up an angle adjustment drive unit, the first drive motor drives the threaded rod to rotate, causing the first connecting block to drive the first rotating plate to tilt the adjustment plate. The angle adjustment drive unit works in conjunction with the auxiliary angle adjustment unit to enable the sliding and rotation of the first slide rod, the first slider, the second slide rod, and the second slider. The pair of first drive motors are symmetrically installed. When one of the first drive motors rotates forward, the other first drive motor rotates in reverse, causing the pair of first connecting blocks to tilt the adjustment plate to the left or right. This solves the problems of limited angle adjustment range and lack of support in existing equipment, which makes it prone to shaking. It enables precise positioning at multiple angles and adapts to the tilt angle requirements of different surface treatment processes for circuit boards.

[0011] By using the clamping unit, rotating the adjusting bolt can push the first clamping plate to move flexibly, which can not only adapt to filter anti-interference circuit boards of different sizes and specifications, but also control the clamping force by manual adjustment, avoiding the problems of circuit board edge damage or component fall-off caused by the existing fixed-size rigid clamping. By using the flipping unit, the first servo motor drives the first rotating shaft to rotate, which drives the lifting plate to rise and fall along the second slide rail. The telescopic rod pushes the moving plate to adjust its position, and then the second servo motor drives the second rotating shaft to flip the circuit board. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0015] Please see Figure 1 - Figure 3 As shown, this embodiment proposes a clamping and reversing structure for surface treatment of a filter anti-interference circuit board, including: a base 1, the upper surface of which is further provided with an auxiliary angle adjustment unit and a translation unit. The auxiliary angle adjustment unit includes a first mounting block 2, a first slide rod 3, a first slider 4, a second slide rod 5, a second slider 6, a connecting shaft 7, a first connecting plate 8, and an adjusting plate 18. Two pairs of first mounting blocks 2 are fixedly connected to the upper surface of the base 1. Two pairs of first slide rods 3 are movably connected to one side of the two pairs of first mounting blocks 2. Two pairs of first sliders 4 are slidably connected to the outer walls of the two pairs of first slide rods 3. A pair of second slide rods 5 are movably connected to the side. A pair of second sliders 6 are slidably connected to the outer wall of the pair of second slide rods 5. A pair of connecting shafts 7 are movably connected to the inner surface of the upper surface of the pair of second sliders 6. A pair of first connecting plates 8 are fixedly connected to the output end of the upper surface of the pair of connecting shafts 7. An adjusting plate 18 is fixedly connected to the upper surface of the pair of first connecting plates 8. A first fixing plate 19 is fixedly connected to the upper surface of the adjusting plate 18. A rotating shaft 20 is movably connected to the upper surface of the first fixing plate 19. Several second connecting blocks 21 are fixedly connected to the upper surface of the adjusting plate 18. A placement plate 22 is fixedly connected to the upper surface of the second connecting blocks 21. In the angle adjustment drive unit, when the adjustment plate 18 tilts, it will drive the first connecting plate 8 to tilt synchronously, and then push the second slider 6 to slide laterally along the outer wall of the second slide rod 5 through the connecting shaft 7. As the second slider 6 slides laterally, the first slider 4, which is movably connected to both ends of the second slide rod 5, will be pushed by the second slide rod 5, and thus drive the first slider 4 to slide longitudinally along the outer wall of the first slide rod 3. Meanwhile, the connecting shaft 7 will rotate flexibly around its own axis, thereby increasing the angle difference of the tilt angle.

[0016] Preferred, such as Figure 2 As shown, the translation unit includes a first slide rail 9, a first air pump 10, a first air rod 11 and a slide plate 12. A pair of first slide rails 9 are fixedly connected to the upper surface of the base 1. The first air pump 10 is fixedly connected to the upper surface of the base 1. The first air rod 11 is fixedly connected to the output end on one side of the first air pump 10. The slide plate 12 is fixedly connected to the output end on one side of the first air rod 11. When it is necessary to move the circuit board on the placement plate 22 to the target processing station, the output end of the first air pump 10 drives the first air rod 11 to extend and retract through compressed air. Under the action of air pressure, the first air rod 11 pushes the slide plate 12 to move, and the slide plate 12 will move forward or backward along the direction of the first slide rail 9, thereby driving the adjustment plate 18 to move back and forth.

[0017] Preferred, such as Figure 2 and Figure 3 As shown, the upper surface of the slide plate 12 is also provided with an angle adjustment drive unit. The angle adjustment drive unit includes a second connecting plate 13, a first drive motor 14, a threaded rod 15, a first connecting block 16, and a first rotating plate 17. A pair of second connecting plates 13 are fixedly connected to the upper surface of the slide plate 12. A pair of first drive motors 14 are fixedly connected to the upper surface of the pair of second connecting plates 13. A pair of threaded rods 15 are fixedly connected to the output end of one side of the pair of first drive motors 14. A pair of first connecting blocks 16 are threadedly connected to the outer wall of the pair of threaded rods 15. A pair of first rotating plates 17 are movably connected to the outer wall of the pair of first connecting blocks 16. One side of the first rotating plate 17 is connected to the interior of the adjustment plate 18. When the tilt angle of the circuit board needs to be adjusted, the first drive motor 14 drives the threaded rod 15 to rotate. The rotation of the threaded rod 15 will drive the first connecting block 16 to move through the thread meshing action. When the first connecting block 16 moves along the axial direction of the threaded rod 15, it will generate a pushing or pulling force on the first rotating plate 17, forcing the first rotating plate 17 to rotate around its connection point with the first connecting block 16, thereby changing its own tilt angle.

[0018] Preferred, such as Figure 1As shown, a clamping unit is also provided on the upper surface of the placement plate 22. The clamping unit includes the placement plate 22, the second fixing plate 23, the adjusting bolt 24 and the first clamping plate 25. A pair of second fixing plates 23 are fixedly connected to the upper surface of the placement plate 22. A pair of adjusting bolts 24 are threadedly connected to the inside of the pair of second fixing plates 23. The first clamping plate 25 is fixedly connected to one side of the pair of adjusting bolts 24. Once the circuit board is in place, the operator rotates the adjusting bolts 24 connected to the internal threads of the pair of second fixing plates 23. When the adjusting bolts 24 are rotated, the thread engagement will convert the rotational motion of the bolts into linear motion along the bolt axis, thereby driving the first clamping plate 25 to flexibly clamp the left and right sides of the circuit board.

[0019] Preferred, such as Figure 1 As shown, the upper surface of the placement plate 22 is also provided with a flipping unit. The flipping unit includes a mounting frame 26, a first servo motor 27, a first rotating shaft 28, a lifting plate 29, a second slide rail 30, a telescopic rod 31, a moving plate 32, a second servo motor 33, a second rotating shaft 34, and a second rotating plate 35. A pair of mounting frames 26 are fixedly connected to the upper surface of the placement plate 22. A pair of first servo motors 27 are fixedly connected to the upper surface of the pair of mounting frames 26. A pair of first rotating shafts 28 are fixedly connected to the output end of the lower surface of the pair of first servo motors 27. A pair of lifting plates 29 are threadedly connected to the outer wall of the pair of first rotating shafts 28. A pair of second slide rails 30 are fixedly connected to the left and right sides of the inner wall of the mounting frame 26. A pair of telescopic rods 31 are fixedly connected to one side of the pair of lifting plates 29. A moving plate 32 is fixedly connected to the output end of one side of the pair of telescopic rods 31. A second servo motor 33 is fixedly connected to one side of the moving plate 32. A second rotating shaft 34 is fixedly connected to the output end of one side of the second servo motor 33. A second rotating plate 35 is fixedly connected to the output end of one side of the second rotating shaft 34. Before using the flipping unit, the first servo motor 27 drives the first rotating shaft 28, thereby causing the lifting plate 29 to descend and adjusting the distance between the second rotating plate 35 and the circuit board at the same horizontal plane. The output end of the telescopic rod 31 extends horizontally, pushing the moving plate 32 to move closer to the circuit board and fit the front and rear sides together. The first servo motor 27 drives the first rotating shaft 28 to reverse, thereby causing the lifting plate 29 to rise and fall. The moving plate 32 will drive the circuit board to rise and fall synchronously. The second servo motor 33 drives the second rotating shaft 34 to rotate, causing the second rotating plate 35 to rotate simultaneously, thus flipping the circuit board.

[0020] When using this utility model, the operator places the filter anti-interference circuit board to be processed stably on the upper surface of the placement plate 22, so that the center of the circuit board is roughly aligned with the center of the placement plate 22, and the initial positioning is completed. After the circuit board is placed, the clamping unit starts first. The operator rotates the adjusting bolts 24 on a pair of second fixing plates 23 respectively. Through the thread engagement, the rotational motion of the bolts is converted into linear motion along the axial direction, which in turn pushes the first clamping plate 25 closer to both sides of the circuit board until the first clamping plate 25 is tightly attached to the edge of the circuit board. According to the position requirements of the surface treatment station, the translation unit is started. The first air pump 10 drives the first air rod 11 to extend and retract through compressed air. The first air rod 11 extends and pushes the slide plate 12 to move smoothly along a pair of first slide rails 9 towards the station. The movement of the slide plate 12 will synchronously drive the adjustment plate 18 to move together until the circuit board reaches directly below the target treatment station. According to the surface treatment process, the angle adjustment drive unit is activated, and the output end of the first drive motor 14 drives the threaded rod 15 to rotate synchronously. Through thread engagement, the first connecting block 16 moves axially along the threaded rod 15. If the adjustment plate 18 needs to be tilted away from the motor, the first connecting block 16 moves towards the motor, generating a thrust on the first rotating plate 17, forcing the first rotating plate 17 to rotate upward around the connection point. If it needs to be tilted towards the motor, the first connecting block 16 moves away from the motor, pulling the first rotating plate 17 to rotate downward. When the auxiliary angle adjustment unit is activated, the first rotating plate 17 pushes or pulls the adjustment plate 18 to tilt. The adjustment plate 18 drives the second slider 6 to slide laterally along the second slide rod 5 through the first connecting plate 8 and the connecting shaft 7. The second slide rod 5 is pushed and slides longitudinally along the first slide rod 3 through the first sliders 4 at both ends. The connecting shaft 7 rotates around its own axis to compensate for the angle difference between the adjustment plate 18 and the second slider 6. After the front side is processed, if the reverse side needs to be processed, the flipping unit is activated. The first servo motor 27 drives the first rotating shaft 28 to rotate, causing the lifting plate 29 to descend along the second slide rail 30 through threaded transmission until the second rotating plate 35 approaches the upper surface of the circuit board. The telescopic rod 31 extends, pushing the moving plate 32 and the second rotating plate 35 towards the circuit board, so that the second rotating plate 35 is in contact with the circuit board. Meanwhile, the first servo motor 27 reverses, causing the lifting plate 29 to rise slightly, simultaneously lifting the circuit board. Then, the second servo motor 33 is activated, driving the second rotating shaft 34 to rotate the second rotating plate 35 and the circuit board. The first servo motor 27 rotates forward, causing the lifting plate 29 to descend, so that the flipped circuit board is re-attached to the placement plate 22. The telescopic rod 31 retracts, and the second rotating plate 35 moves away from the circuit board, completing the flipping process.
