Description

Technical Field

[0001] This application relates to the technical field of circuit board processing, and in particular to a circuit board processing positioning device. Background Technology

[0002] In the fabrication of rigid circuit boards, there are several key steps that require clamping the circuit board to ensure the accuracy and safety of the process, including but not limited to drilling, hole metallization, and pattern transfer.

[0003] In related technologies, spring clamping is generally used. However, circuit boards of different sizes experience different spring forces. When the spring force on a circuit board is too great, directly removing the board may damage it, reducing the board's yield. Therefore, those skilled in the art have provided a circuit board processing positioning device to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a circuit board processing positioning device.

[0005] The circuit board processing positioning device provided in this application adopts the following technical solution:

[0006] A circuit board processing positioning device includes a mounting plate. The top of the mounting plate is provided with a plurality of fixing components. Each fixing component includes a vertical plate fixedly connected to the top of the mounting plate. A first limiting plate is fixedly connected to one side of the vertical plate via a telescopic part. Two clamping parts are fixedly connected to the top of the mounting plate, and a second limiting plate is fixedly connected to the top of the mounting plate.

[0007] By adopting the above technical solution, the circuit board is placed inside the fixing assembly, and the circuit board is initially limited by the first limiting plate. At this time, the second limiting plate is pushed by the telescopic part, which in turn pushes the circuit board closer to the two clamping parts, clamping and fixing one end of the circuit board. This allows circuit boards of different sizes to be clamped and fixed. When it is necessary to remove the circuit board, simply activate the telescopic part to move the second limiting plate away from the clamping parts, thereby releasing the clamping parts from fixing the circuit board and allowing the circuit board to be removed. This avoids directly removing the circuit board and causing damage, thus ensuring the quality of the circuit board.

[0008] Preferably, the clamping part includes a support plate fixedly connected to the mounting plate, a connecting plate fixedly connected to one side of the support plate, a connecting rod slidably connected to the bottom of the connecting plate, an abutment rod fixedly connected to one side of the connecting rod, and an elastic connection between the other side of the connecting rod and the support plate via a spring.

[0009] By adopting the above technical solution, the clamping part facilitates the clamping and fixing of the circuit board, enhancing the stability of the circuit board fixing. The spring can adjust the clamping force on the circuit board, providing a buffering effect and protecting the circuit board.

[0010] Preferably, a limiting hole is provided on the upper part of the connecting plate, a limiting rod is slidably connected through the limiting hole, and a pressing plate is fixedly connected to the bottom of the limiting rod.

[0011] By adopting the above technical solution, and by setting limit blocks and limit rods, it is easy to limit the running trajectory of the pressing plate, enhance the stability of the device during operation, and the pressing plate can press and fix the top of the circuit board, thereby improving the stability of the circuit board clamping.

[0012] Preferably, a slider is slidably connected to the connecting rod, one side of the slider is hinged to the support plate via a first connecting rod, and the other side of the slider is hinged to one end of the pressing plate via a second connecting rod.

[0013] By adopting the above technical solution, and by setting up a slider, a first connecting rod, and a second connecting rod, the movement of the abutment rod drives the connecting rod to move, and then, under the transmission of the first connecting rod and the second connecting rod, the pressing plate is driven to descend and press and fix the top of the circuit board, thereby further improving the stability of the circuit board clamping.

[0014] Preferably, a limiting block is fixedly connected to the top of the connecting rod, and a groove for use with the limiting block is provided at the bottom of the connecting plate.

[0015] By adopting the above technical solution, the setting of limit blocks and grooves facilitates the restriction of the running trajectory of the connecting rod, improves the stability of the device during operation, and facilitates the installation of the connecting rod.

[0016] Preferably, a protective pad is fixedly connected to one side of the bottom of the pressing plate.

[0017] By adopting the above technical solution, the protective pad can protect the circuit board when the pressing plate presses and fixes it.

[0018] Preferably, the telescopic part includes an electric telescopic rod fixedly connected to one side of the upright plate, and the output end of the electric telescopic rod is fixedly connected to the first limiting plate.

[0019] By adopting the above technical solution, the first limiting plate is moved by the electric telescopic rod, thereby clamping and fixing circuit boards of different sizes.

[0020] In summary, this application has the following beneficial technical effects:

[0021] This circuit board processing and positioning device works by placing the circuit board inside a fixing assembly. A second limiting plate initially limits the circuit board's position. Then, a telescopic component pushes the first limiting plate, causing it to move the circuit board closer to two clamping parts, clamping and fixing one end of the circuit board. This allows for clamping and fixing circuit boards of different sizes. When the circuit board needs to be removed, simply activating the telescopic component moves the first limiting plate away from the clamping parts, releasing the clamping parts from the circuit board and allowing it to be removed. This avoids damage to the circuit board from direct removal, ensuring the quality of the circuit board.

[0022] When the circuit board processing and positioning device clamps and fixes the circuit board, the first limiting plate pushes the circuit board to move, the circuit board pushes the abutment rod to move, and then drives the connecting rod to move. Under the transmission of the first connecting rod and the second connecting rod, the pressing plate is driven to descend and press and fix the top of the circuit board, further improving the stability of the circuit board clamping.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] This application discloses a circuit board processing positioning device. (Refer to...) Figure 1-3A circuit board processing positioning device includes a mounting plate 1. The top of the mounting plate 1 is provided with a plurality of fixing components 2. The fixing components 2 include a vertical plate 21 fixedly connected to the top of the mounting plate 1. A first limiting plate 23 is fixedly connected to one side of the vertical plate 21 through a telescopic part 22. Two clamping parts 24 are fixedly connected to the top of the mounting plate 1. A second limiting plate 25 is fixedly connected to the top of the mounting plate 1.

[0029] The clamping part 24 includes a support plate 2401 that is fixedly connected to the mounting plate 1. A connecting plate 2402 is fixedly connected to one side of the support plate 2401. A connecting rod 2403 is slidably connected to the bottom of the connecting plate 2402. An abutment rod 2404 is fixedly connected to one side of the connecting rod 2403, and the other side is elastically connected to the support plate 2401 through a spring 2405.

[0030] The top of the connecting rod 2403 is fixedly connected to a limiting block 2412, and the bottom of the connecting plate 2402 is provided with a groove 2413 for use with the limiting block 2412.

[0031] The telescopic part 22 includes an electric telescopic rod 221 that is fixedly connected to one side of the upright plate 21, and the output end of the electric telescopic rod 221 is fixedly connected to the first limiting plate 23.

[0032] In the above embodiment, when clamping and fixing the circuit board, the circuit board is first placed on one side of the first limiting plate 23, and the circuit board is initially limited by the first limiting plate 23. At this time, by activating the electric telescopic rod 221, the second limiting plate 25 is moved closer to the clamping part 24, and the circuit board is brought closer to the abutment rod 2404. The abutment rod 2404 pushes the connecting rod 2403, causing the connecting rod 2403 to move the limiting block 2412 to slide inside the groove 2413. At this time, the spring 2405 is compressed, clamping and fixing the circuit board. The spring 2405 can be adjusted to fix the circuit board. The clamping force acts as a buffer to protect the circuit board. When it is necessary to remove the circuit board, the electric telescopic rod 221 is activated to move the second limiting plate 25 away from the clamping part 24. At this time, the spring 2405 pushes the connecting rod 2403, which causes the limiting block 2412 to slide inside the groove 2413. This, in turn, drives the abutment rod 2404 to push the circuit board away from the clamping part 24, making it easier for the user to remove the circuit board. This avoids directly removing the circuit board and damaging it, thus ensuring the quality of the circuit board.

[0033] In this embodiment of the application, the mounting plate 1 can be drilled according to actual needs to meet the requirements of drilling and metallization of the holes. Drilling is mainly performed by a CNC machine tool to drill holes in the circuit board in order to install electronic components, while metallization of the holes is to perform metallization treatment on the drilled holes so as to form conductive channels in subsequent steps.

[0034] It is understandable that the spring 2405 of this application can also be combined with a damping system to make the whole more stable, such as by combining silicone, rubber and damping cylinder, etc. This is prior art, so it will not be explained in detail here.

[0035] Furthermore, a limiting hole 2406 is provided on the upper part of the connecting plate 2402, a limiting rod 2407 is slidably connected through the limiting hole 2406, and a pressing plate 2408 is fixedly connected to the bottom of the limiting rod 2407.

[0036] A slider 2409 is slidably connected to the connecting rod 2403. One side of the slider 2409 is hinged to the support plate 2401 through the first connecting rod 2410, and the other side of the slider 2409 is hinged to one end of the pressing plate 2408 through the second connecting rod 2411.

[0037] Based on the above embodiment, when the circuit board abuts against the abutment rod 2404, the abutment rod 2404 drives the connecting rod 2403 to move, causing the limiting block 2412 to slide inside the groove 2413. At this time, the spring 2405 is compressed, and simultaneously the first connecting rod 2410 starts to rotate, driving the slider 2409 to move on the connecting rod 2403, thereby driving the second connecting rod 2411 to start rotating and driving the pressing plate 2408 to move. At this time, the limiting rod 2407 slides inside the limiting hole 2406, and the pressing plate 2408 begins to descend to press and fix the circuit board. To further improve the stability of fixing the circuit board, when the circuit board is released, the elastic force of the spring 2405 pushes the connecting rod 2403 to move, which in turn moves the contact to remove the circuit board from the clamping part 24. At the same time, the first connecting rod 2410 rotates as the connecting rod 2403 moves, and drives the slider 2409 to rise. At this time, the second connecting rod 2411 starts to rotate. Under the restriction of the limiting rod 2407 and the limiting hole 2406, it drives the pressing plate 2408 to rise, which in turn contacts the fixing of the top of the circuit board, making it easier to remove the circuit board and improving the convenience of the device.

[0038] Furthermore, a protective pad 2414 is fixedly connected to one side of the bottom of the pressing plate 2408. The protective pad 2414 is made of flexible materials such as rubber and silicone.

[0039] Based on the above embodiments, the protective pad 2414 can protect the circuit board when the pressing plate 2408 presses and fixes it.

[0040] It should be understood that, in the embodiments of this application, the protective pad 2414 is in contact with the edge of the circuit board to avoid interference during the processing of the circuit board.

[0041] The implementation principle of the circuit board processing positioning device in this application embodiment is as follows: First, the circuit board is placed on one side of the second limiting plate 25. The adjacent second limiting plate 25 can initially guide and limit the circuit board. At this time, by activating the telescopic part 22, the first limiting plate 23 is pushed, so that the first limiting plate 23 pushes the circuit board closer to the two clamping parts 24 to clamp and fix the circuit board. Thus, circuit boards of different sizes can be clamped and fixed. When it is necessary to remove the circuit board, it is only necessary to activate the telescopic part 22 to move the first limiting plate 23 away from the clamping part 24, so that the clamping part 24 can release the fixation of the circuit board to the circuit board, and then the circuit board can be removed. This avoids directly removing the circuit board and causing damage to the circuit board, thus ensuring the quality of the circuit board.

[0042] It is understood that the embodiments of this application refer to rigid circuit boards, not FPC flexible circuit boards.

[0043] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
