Description

Technical Field

[0001] This utility model relates to the field of FPC circuit board processing technology, specifically to a limiting mechanism for FPC circuit board processing. Background Technology

[0002] Circuit boards, also known as printed circuit boards, are commonly classified as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, etc. Circuit boards make circuits miniaturized and more intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. During the circuit board processing, it is often necessary to clamp and fix the circuit board and perform operations.

[0003] A search revealed patent CN212727570U, which discloses a positioning device for circuit board processing. Through the coordinated action of a mounting box, a first lead screw, a second lead screw, a transmission block, a bevel gear ring, a rotating rod, a handle, a bevel gear, a transmission rod, a transmission plate, a lifting hole, a lifting rod, a lifting plate, a pressure plate, a fixing rod, a fixing plate, and a support plate, it effectively simplifies the operation required for positioning circuit boards, significantly improving the ease of operation and practicality of the circuit board positioning equipment. However, this device directly limits the movement of the FPC circuit board without any buffering measures in place, making it prone to damage and scrapping of the FPC circuit board during positioning. Therefore, we propose a limiting mechanism for FPC circuit board processing. Utility Model Content

[0004] The purpose of this utility model is to provide a limiting mechanism for FPC circuit board processing.

[0005] To address the problems mentioned in the background art, this utility model provides the following technical solution: a limiting mechanism for FPC circuit board processing, comprising a device body, mounting seats installed on both the front and back of the upper end of the device body, a motor disposed at the center of the right side wall of the mounting seat, a spiral rod disposed on the left side wall of the motor, a stabilizing plate installed on the inner wall of the mounting seat near the upper side, limiting seats installed on both sides of the outer wall of the stabilizing plate, a first friction plate installed on the lower side of the inner wall of the limiting seat, a second friction plate installed on the upper end of the first friction plate, a sliding plate installed on the upper end of the second friction plate, and a slider penetratingly disposed on both the front and back sides of the upper end of the limiting seat, with a clamping box installed at the lower end of the slider.

[0006] Preferably, the spiral rod has a groove at the contact point with the mounting base, and the spiral directions on both sides of the spiral rod are opposite.

[0007] Preferably, the sliding plate and the clamping box are provided with sliding grooves at the contact positions, and the center of the upper end of the mounting base is provided with a first threaded post.

[0008] Preferably, the upper end of the skateboard is elastically connected to multiple sets of springs, and the springs are located inside the clamping box, wherein the number of springs is ten.

[0009] Preferably, mounting plates are installed on both the front and back sides of the inner wall of the mounting base. A second threaded post is provided through the center of the outer wall of the mounting plate. A limit plate is installed on the inner wall of the second threaded post. A bottom block is installed on the lower side of the inner wall of the device body. A connecting plate is installed on the upper end of the bottom block. A first rotating block is provided on the outer wall of the connecting plate. A support plate is installed on the upper end of the first rotating block. A second rotating block is installed on the lower end of the support plate near the left side.

[0010] Preferably, the inner wall of the second rotating block is movably connected to a movable block, and the lower end of the movable block is fixedly connected to an electric push rod.

[0011] Preferably, a rotating column is provided through the center of the front side of the second rotating block, and a rotating column is provided through the center of the front side of the first rotating block.

[0012] By adopting the above technical solution, rotating the first threaded column causes the second friction plate to rise through the cooperation of the clamping box and the sliding plate, thus creating a gap between the second and third friction plates. Then, the motor is started, causing the auger to rotate inside the mounting base through the cooperation of the rotating groove. When the mounting base rotates, it drives the limiting seats to move closer to each other inside the mounting base through the stabilizing plate. Then, the FPC circuit board is placed between the first and second friction plates. When the inner wall of the limiting seat is in complete contact with the FPC circuit board, the movement stops. Then, rotating the first threaded column causes the second friction plate to move closer to the first friction plate again through the cooperation of the clamping box and the sliding plate, thus limiting the position of the FPC circuit board. Conversely, it can be removed. At the same time, through the action of the spring, the first friction plate, and the second friction plate, the limiting effect of the FPC circuit board is better, and no damage is caused to the FPC circuit board. This allows the limiting mechanism for FPC circuit board processing to quickly limit the FPC board and prevent damage to the FPC circuit board when it is limited, thus reducing the scrap rate during FPC circuit board processing.

[0013] By adopting the above technical solution, after the FPC circuit board is processed, it is removed, allowing most of the debris generated during processing to fall directly into the main body of the device. The remaining debris falls onto the support plate. Then, the electric push rod is activated, driving the movable block upwards. The movable block, in cooperation with the second rotating block and the rotating column, drives the support plate to rotate to the right on the connecting plate, passing through the first rotating block and the rotating column. During this rotation, debris on the surface of the support plate falls into the main body of the device. After the debris has fallen, the electric push rod is activated again, returning the support plate to its original position for the next processing. Then, the user can directly clean the inside of the main body of the device. Simultaneously, the support plate supports the lower end of the FPC circuit board, preventing breakage during processing. This enhances the functionality of the FPC circuit board processing limiting mechanism, allowing for rapid cleaning of debris generated during processing after the FPC circuit board is finished.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1:

[0021] Please see Figure 1-4 This utility model provides a technical solution: a limiting mechanism for FPC circuit board processing, including a device body 1. Mounting seats 2 are installed on the front and back of the upper end of the device body 1. A motor 3 is arranged at the center of the right side wall of the mounting seat 2. A spiral rod 4 is arranged on the left side wall of the motor 3. A stabilizing plate 5 is installed on the inner wall of the mounting seat 2 near the upper side. Limiting seats 6 are installed on the outer side of the stabilizing plate 5 near both sides. A first friction plate 7 is installed on the lower side of the inner wall of the limiting seat 6. A second friction plate 8 is installed on the upper end of the first friction plate 7. A sliding plate 9 is installed on the upper end of the second friction plate 8. A slider 12 is provided through the upper end of the limiting seat 6 near the front and back. A clamping box 11 is installed on the lower end of the slider 12.

[0022] The spiral rod 4 has a groove at the point where it contacts the mounting base 2, and the spiral directions on both sides of the spiral rod 4 are opposite.

[0023] The sliding plate 9 and the clamping box 11 are provided with sliding grooves at the contact points, and the first threaded post 13 is provided through the center of the upper end of the mounting base 2.

[0024] The upper end of the skateboard 9 is elastically connected to multiple sets of springs 10, and the springs 10 are located inside the clamping box 11, with a total of ten springs 10.

[0025] The upper end of the slide plate 9 is elastically connected to multiple sets of springs 10, and the springs 10 are located inside the clamping box 11, with ten springs 10 in total. In use, rotating the first threaded post 13 causes the clamping box 11 to rise. At this time, the clamping box 11, via the slide plate 9, causes the second friction plate 8 to rise, creating a gap between it and the first friction plate 7. Then, the motor 3 is started, causing the screw rod 4 to rotate through the slot inside the mounting base 2. As the mounting base 2 rotates, it drives the limiting seats 6 to move closer together inside the mounting base 2 via the stabilizing plate 5. Then, the FPC circuit board is placed between the first friction plate 7 and the second friction plate 8. When the inner wall of the limiting seat 6 is completely in contact with the FPC circuit board, the movement stops. Then, rotating the first threaded post 13 causes the clamping box 11 to descend. As the clamping box 11 descends, the second friction plate 8 moves closer together via the slide plate 9. Plate 9 moves closer to the first friction plate 7 and restricts the position of the FPC circuit board; conversely, it moves away. Simultaneously, the elasticity of spring 10 provides a buffer when the second friction plate 8 limits the FPC circuit board. Furthermore, the materials of the first and second friction plates 7 and 8 prevent the FPC circuit board from moving, thus improving the limiting effect and preventing damage. The stabilizing plate 5 further stabilizes the limiting seats 6 when they approach each other, enabling the limiting mechanism for FPC circuit board processing to quickly limit the FPC board and preventing damage during limiting, thereby reducing the scrap rate during FPC circuit board processing.

[0026] Example 2:

[0027] Please see Figure 1-4 This utility model provides a technical solution: a limiting mechanism for FPC circuit board processing. Mounting plates 14 are installed on both the front and back sides of the inner wall of the mounting base 2. A second threaded post 15 is provided through the center of the outer side wall of the mounting plate 14. A limiting plate 16 is installed on the inner side wall of the second threaded post 15. A bottom block 17 is installed on the lower side of the inner wall of the device body 1. A connecting plate 18 is installed on the upper end of the bottom block 17. A first rotating block 19 is provided on the outer side wall of the connecting plate 18. A support plate 20 is installed on the upper end of the first rotating block 19. A second rotating block 21 is installed on the lower end of the support plate 20 near the left side.

[0028] The inner wall of the second rotating block 21 is movably connected to a movable block 22, and the lower end of the movable block 22 is fixedly connected to an electric push rod 23.

[0029] A rotating post 24 is provided through the center of the front of the second rotating block 21, and a rotating post 24 is provided through the center of the front of the first rotating block 19.

[0030] Specifically, after the FPC circuit board is processed, it is removed, allowing most of the debris generated during processing to fall directly into the main body 1 of the device. The remaining debris falls onto the support plate 20. Then, the electric push rod 23 is activated, causing the movable block 22 to rise. The movable block 22 then rotates via the mounting plate 14 in the second rotating block 21, thereby driving the support plate 20 to rotate to the right on the connecting plate 18 via the first rotating block 19 and the rotating column 24. During this rotation, debris on the surface of the support plate 20 falls into the main body 1 of the device. After the debris has fallen out, the electric push rod 23 is activated again, causing the support plate 20 to return to its original position. Returning the device to its original position facilitates the next processing. Then, the user can directly clean the inside of the main body 1. At the same time, the support plate 20 supports the lower end of the FPC circuit board, making it less likely to break during processing. Rotating the second threaded column 15 pushes the limiting plate 16 towards the FPC circuit board, allowing the limiting plate 16 to fix and limit the front and back of the FPC circuit board. This enables the limiting mechanism for FPC circuit board processing to quickly clean up the debris generated during processing after the FPC circuit board is processed, thus improving the functionality of the limiting mechanism for FPC circuit board processing.

It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
