Description

Technical Field

[0001] This utility model relates to the field of PCBA assembly spacing technology, and in particular to a PCBA assembly spacing structure. Background Technology

[0002] PCBA (Printed Circuit Board Assembly) refers to the finished product formed by assembling electronic components onto a printed circuit board (PCB) through specific processes. In other words, it is the entire process of a bare PCB board undergoing SMT (Surface Mount Technology) component mounting or DIP (Dual In-line Package) insertion. It is commonly referred to as PCBA in China, while the standard writing in Europe and America is PCB'A with an apostrophe, which is considered the official usage.

[0003] Spacing structures refer to structural designs used to separate and position components, PCB layers, or different functional areas. They play an important role in ensuring the performance and reliability of PCBA assemblies, ensuring that adjacent components maintain a certain distance, and avoiding solder bridging or short circuits between component pins due to insufficient spacing, which would affect the normal operation of the circuit.

[0004] Chinese patent application publication number CN222081180U discloses a PCBA board support structure. This invention uses a drive mechanism to drive several support columns to rotate synchronously, causing changes in the spacing between the corresponding support surfaces of the columns, thus creating support cavities of various sizes. During placement, because the support surfaces are inclined relative to the chassis surface, compared to cylindrical surfaces without inclined support surfaces, the inclined support surfaces can achieve more line contact with PCBA boards of different sizes, providing a more stable support effect and meeting the needs of stacking PCBA boards of various sizes. While this invention supports PCB boards by setting multiple support mechanisms to achieve spaced placement, the inability to limit the drive mechanism during synchronous rotation of the support columns allows it to easily rotate, causing changes in the spacing between support surfaces during support and potentially leading to PCBA boards detaching, affecting support. Furthermore, the lack of a mechanism to press the PCBA boards firmly allows them to easily fall from the sides, hindering proper support. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a PCBA assembly spacing structure, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A PCBA assembly spacing structure includes a base, an mounting plate fixedly mounted inside the base via a moving mechanism, a slide rail mounted inside the base via the moving mechanism, a first mounting groove formed on the surface of the mounting plate, an mounting cylinder fixedly mounted on one side of the base, a first mounting post mounted on the inner wall of the mounting cylinder via a first reset mechanism, a second mounting groove formed on the inner wall of the slide rail, a slider slidably mounted on the inner wall of the slide rail, a slot formed inside the slider, a second mounting post mounted on the inner wall of the slot via a second reset mechanism, a support post fixedly mounted on the top of the slider, and a clamping mechanism provided on one side of the support post.

[0008] Preferably, the moving mechanism includes a bidirectional threaded rod rotatably mounted inside the base, a moving block being threadedly fitted onto the surface of the bidirectional threaded rod, one end of the bidirectional threaded rod being fixedly mounted to one side of the mounting plate, and the top of the moving block being fixedly mounted to the bottom of the slide rail.

[0009] Preferably, the first reset mechanism includes a first sliding column slidably mounted on the inner wall of the mounting cylinder, a first sliding plate fixedly mounted on one end of the first sliding column, a first spring fixedly mounted on the inner wall of the mounting cylinder, one end of the first spring and one side of the first sliding plate being fixedly mounted, and one side of the first sliding plate and one end of the first mounting column being fixedly mounted.

[0010] Preferably, the second reset mechanism includes a second sliding column slidably mounted on the inner wall of the slot, a second sliding plate fixedly mounted on one end of the second sliding column, a second spring fixedly mounted on the inner wall of the slot, one end of the second spring and one side of the second sliding plate being fixedly mounted, and one side of the second sliding plate and one end of the second mounting column being fixedly mounted.

[0011] Preferably, the clamping mechanism includes a U-shaped plate fixedly installed on one side of the support column, a lead screw threaded onto the inner wall of the U-shaped plate, and a pressure plate provided at one end of the lead screw.

[0012] Preferably, the top of the base is provided with a sliding groove, and the inner wall of the sliding groove is in contact with the surface of the moving block.

[0013] Preferably, the inner wall of the first mounting groove mates with the surface of the first mounting post, and the inner wall of the second mounting groove mates with the surface of the second mounting post.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Multiple PCBA boards can be pressed together by multiple pressing mechanisms to prevent them from falling off. At the same time, each PCBA board has a certain distance between them so that they will not affect each other. The first reset mechanism drives the first mounting post away from the inner wall of the first mounting groove. The moving mechanism can then drive the U-shaped plate to move in opposite directions to adjust the distance of the pressing mechanism. After adjustment, the first reset mechanism drives the first mounting post to insert into the inner wall of the first mounting groove to limit the mounting plate, which in turn limits the moving mechanism. This makes the moving mechanism more stable and facilitates the placement and pressing of PCBA boards of different lengths.

[0016] 2. By using the second reset mechanism to move the second mounting post away from the inner wall of the second mounting groove, the positions of the slider and the support post can be moved. After adjustment, the second reset mechanism moves the second mounting post into the inner wall of the second mounting groove to complete the limit installation of the slider, thereby adjusting the distance of the clamping mechanism. This facilitates the placement and clamping of PCBA boards of different widths, achieving the purpose of facilitating the limitation of the moving mechanism and the clamping of the PCBA board. The structure is simple and easy to use. Attached Figure Description

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.

[0023] Example: Refer to Figure 1-4 This utility model provides a technical solution: a PCBA assembly spacing structure, including a base 1. An mounting plate 4 is fixedly installed inside the base 1 via a moving mechanism. A slide rail 11 is also installed inside the base 1 via the moving mechanism. The moving mechanism includes a bidirectional threaded rod 2 rotatably installed inside the base 1. A moving block 3 is threadedly fitted onto the surface of the bidirectional threaded rod 2. One end of the bidirectional threaded rod 2 is fixedly installed to one side of the mounting plate 4, facilitating rotation of the mounting plate 4. The top of the moving block 3 is fixedly installed to the bottom of the slide rail 11, facilitating movement of the slide rail 11. A groove 23 is formed on the top of the base 1, and the inner wall of the groove 23 fits against the surface of the moving block 3, limiting the movement of the moving block 3 and making its movement more stable. A first mounting groove 5 is formed on the surface of the mounting plate 4. An mounting cylinder 6 is fixedly installed on one side of the base 1. A first mounting post 10 is installed on the inner wall of the mounting cylinder 6 via a first reset mechanism. The first reset mechanism includes a first sliding post 7 slidably installed on the inner wall of the mounting cylinder 6. One end of the first sliding post 7 is fixedly installed with a first sliding... A first spring 8 is fixedly installed on the inner wall of the mounting cylinder 6. One end of the first spring 8 is fixedly installed on one side of the first sliding plate 9. One side of the first sliding plate 9 is fixedly installed on one end of the first mounting post 10, which facilitates the first mounting post 10 to be moved back to its original position. A second mounting groove 12 is opened on the inner wall of the slide rail 11. A slider 13 is slidably installed on the inner wall of the slide rail 11. A slot 14 is opened inside the slider 13. A second mounting post 18 is installed on the inner wall of the slot 14 through a second reset mechanism. The second reset mechanism includes a second sliding post 15 slidably installed on the inner wall of the slot 14. A second sliding plate 17 is fixedly installed on one end of the second sliding post 15. A second spring 16 is fixedly installed on the inner wall of the slot 14. One end of the second spring 16 is fixedly installed on one side of the second sliding plate 17. One side of the second sliding plate 17 is fixedly installed on one end of the second mounting post 18, which facilitates the second mounting post 18 to be moved back to its original position. The inner wall of the first mounting groove 5 and the surface of the first mounting post 10 are matched. The inner wall of the second mounting groove 12 and the surface of the second mounting post 18 are matched.

[0024] Specifically, a support column 19 is fixedly installed on the top of the slider 13. A clamping mechanism is provided on one side of the support column 19. The clamping mechanism includes a U-shaped plate 20 fixedly installed on one side of the support column 19. A lead screw 21 is threaded onto the inner wall of the U-shaped plate 20. A pressure plate 22 is provided at one end of the lead screw 21 to facilitate clamping. Multiple clamping mechanisms can clamp multiple PCBA boards to prevent them from falling off. At the same time, each PCBA board has a certain distance between them so that they will not affect each other. The first reset mechanism drives the first mounting column 10 away from the inner wall of the first mounting groove 5. The moving mechanism can then drive the U-shaped plate 20 to move in opposite directions to adjust the distance of the clamping mechanism. After adjustment, the first reset mechanism... The mechanism drives the first mounting post 10 to insert into the inner wall of the first mounting groove 5, thereby limiting the mounting plate 4 and the moving mechanism, resulting in better stability of the moving mechanism and facilitating the placement and clamping of PCBA boards of different lengths.

After adjustment, the second reset mechanism drives the second mounting post 18 to insert into the inner wall of the second mounting groove 12, thereby completing the limiting installation of the slider 13 and adjusting the distance of the clamping mechanism, which facilitates the placement and clamping of PCBA boards of different widths. This achieves the purpose of facilitating the limiting of the moving mechanism and the clamping of the PCBA boards. The structure is simple and easy to use.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0026] In use: When using this PCBA assembly spacer structure, multiple PCBA boards are placed inside multiple U-shaped plates 20. Rotating the lead screw 21 lowers the pressure plate 22, thus pressing the PCBA boards to prevent them from falling off. Simultaneously, each PCBA board has a certain spacing, preventing them from interfering with each other. Pulling the first sliding column 7 moves the first sliding plate 9, which in turn moves the first mounting column 10 away from the inner wall of the first mounting groove 5. Rotating the bidirectional threaded rod 2 then moves two sets of moving blocks 3 in opposite directions. The moving blocks 3 move two sets of slide rails 11 in opposite directions, which in turn move the U-shaped plates 20 in opposite directions, thus adjusting the distance of the pressing mechanism. After adjustment, the first spring 8 drives the first mounting column 10 to insert into the first mounting groove 5. The inner wall of the groove 5 can limit the mounting plate 4, thereby limiting the moving mechanism, making the moving mechanism more stable and facilitating the placement and clamping of PCBA boards of different lengths. By pulling the second sliding column 15, the second sliding plate 17 is moved. The second sliding plate 17 moves the second mounting column 18 away from the inner wall of the second mounting groove 12, thereby moving the position of the slider 13 and the support column 19. After adjustment, the second spring 16 moves the second sliding plate 17, which moves the second mounting column 18 into the inner wall of the second mounting groove 12, thus completing the limiting installation of the slider 13 and adjusting the distance of the clamping mechanism. This facilitates the placement and clamping of PCBA boards of different widths, achieving the purpose of facilitating the limiting of the moving mechanism and the clamping of the PCBA boards. The structure is simple and easy to use.
