Description

Technical Field

[0001] This utility model relates to the field of PCB board technology, specifically to a PCB board reference point protection device. Background Technology

[0002] The reference point on the PCB board, also known as the Mark point, is the position identification point of the PCB used in automatic placement machines in circuit board design. For PCBs that serve as carriers for electronic components, it is even more important to have a precise positioning function.

[0003] During PCB manufacturing, multiple surface cleaning and roughening brushing steps are performed. This can cause the reference points exposed on the board surface to be easily scratched and deformed, leading to unrecognizable issues during subsequent automatic placement, thus affecting production efficiency.

[0004] To improve this situation, traditional PCB boards cover the surface of the reference points with a protective film. The protective film is manually removed during SMT assembly, but this also means that the protective film cannot be re-attached, resulting in poor reusability and uncontrollable costs. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A PCB board reference point protection device includes a circuit board mechanism and a protective mechanism. The circuit board mechanism includes a PCB board body, two Mark points located on the top of the PCB board body, and two partition areas. The two Mark points are respectively located inside the two partition areas. The protective mechanism includes a ferromagnetic ring fixed inside the partition area, a cap attached to the top of the ferromagnetic ring, a plurality of magnetic sheets embedded in the bottom of the cap, and a glass sheet embedded in the top of the cap.

[0008] By adopting the above technical solution, the cap protects the Mark point inside. Then, multiple magnetic sheets work together to attract the ferromagnetic ring, keeping the cap upright and unaffected by external forces. This effectively protects the Mark point. Before SMT assembly, the cap can be easily removed to expose the Mark point. The operation is extremely simple and fast, and it does not damage the PCB board or the Mark point surface. It is also highly repeatable and cost-effective.

[0009] In a preferred embodiment, the present invention can be further configured such that: the PCB board has multiple positioning holes arranged in a matrix.

[0010] In a preferred embodiment, the present invention can be further configured such that: both the inner and outer sides of the partition area are provided with barriers, the cap is inserted between the two barriers, and the bottom of the barriers is fixedly connected to the top of the partition area.

[0011] In a preferred embodiment, the present invention can be further configured such that a protective film is adhered to both the top of the ferromagnetic magnetic ring and the bottom of the magnetic sheet, and the protective film is set to blue.

[0012] In a preferred embodiment, the present invention can be further configured such that the top of the ferromagnetic ring is located on the same horizontal plane as the top of the PCB board, and the thickness of the ferromagnetic ring is equal to the thickness of the magnetic sheet.

[0013] In a preferred embodiment, the present invention can be further configured as follows: multiple magnetic sheets are arranged in a ring with equal spacing, and the bottom of the magnetic sheets is attached to the top of the ferromagnetic magnetic ring.

[0014] In a preferred embodiment, the present invention can be further configured such that: multiple locking blocks are integrally formed on the outer side of the glass slide, the multiple locking blocks are equally spaced and arranged in a ring, and the top of the glass slide is flush with the top of the cap.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, the cap protects the Mark point inside, and then multiple magnetic sheets work together to attract the ferromagnetic magnetic ring, so that the cap stands upright and does not move under the influence of external force, thus effectively protecting the Mark point. Then, before SMT placement, the Mark point can be easily exposed by simply pulling it off. The operation is extremely simple and fast, and it does not damage the PCB board or the surface of the Mark point. At the same time, it has strong repeatability and controllable cost.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a PCB board reference point protection device.

[0032] Example 1:

[0033] Combination Figure 1-5 As shown, the present invention provides a PCB board reference point protection device, including a circuit board mechanism 100 and a protection mechanism 200. The circuit board mechanism 100 includes a PCB board body 110, two Mark points 120 disposed on the top of the PCB board body 110 and two partition areas 130. The two Mark points 120 are respectively located inside the two partition areas 130.

[0034] The protective mechanism 200 includes a ferromagnetic ring 210 fixed inside the partition area 130, a cap 220 that is attached to the top of the ferromagnetic ring 210, a plurality of magnetic sheets 230 embedded in the bottom of the cap 220, and a glass sheet 240 embedded in the top of the cap 220.

[0035] Furthermore, the PCB board 110 is provided with a plurality of positioning holes 300 arranged in a matrix. The positioning holes 300 are used to precisely fix and position the tubular mechanical structure of the PCB board 110, and run through the entire manufacturing, assembly and testing process of the PCB board 110, thereby optimizing the processing effect of the PCB board 110.

[0036] Furthermore, the top of the ferromagnetic ring 210 is located on the same horizontal plane as the top of the PCB board 110, and the thickness of the ferromagnetic ring 210 is equal to the thickness of the magnetic sheet 230. This uniform size design, to a certain extent, ensures the aesthetics of the PCB board 110.

[0037] Furthermore, multiple magnetic sheets 230 are arranged in a ring with equal spacing, and the bottom of the magnetic sheets 230 is attached to the top of the ferromagnetic magnetic ring 210. The layout design of the magnetic sheets 230 can improve the adsorption between the cap 220 and the ferromagnetic magnetic ring 210.

[0038] Furthermore, the outer side of the glass slide 240 is integrally formed with multiple locking blocks, which are equally spaced and arranged in a ring. The top of the glass slide 240 is flush with the top of the cap 220. The locking blocks can increase the contact area between the glass slide 240 and the cap 220, making the glass slide 240 more securely installed. In addition, the transparency of the glass slide 240 allows for rough visual inspection of the Mark point 120 under protective conditions.

[0039] Example 2:

[0040] Combination Figure 1 and Figure 3 As shown, based on Embodiment 1, the partition area 130 is provided with a barrier 400 on both the inner and outer sides. The cap 220 is inserted between the two barriers 400. The bottom of the barrier 400 is fixed to the top of the partition area 130. The barrier 400 enhances the dust and splash prevention effect and improves the protection of Mark point 120.

[0041] Example 3:

[0042] Combination Figure 5 As shown, in the above embodiment, a protective film 500 is adhered to the top of the ferromagnetic magnetic ring 210 and the bottom of the magnetic sheet 230. The protective film 500 is set to blue. The protective film 500 can prevent the ferromagnetic magnetic ring 210 and the magnetic sheet 230 from being scratched and effectively maintain the magnetism of the magnetic sheet 230.

[0043] The working principle and usage process of this utility model are as follows: In the initial state, the cap 220 protects the Mark point 120. Then, multiple magnetic sheets 230 work together to attract the ferromagnetic magnetic ring 210, so that the cap 220 stands upright without being affected by external force, thus effectively protecting the Mark point 120. Before SMT placement, the cap can be easily removed to expose the Mark point 120. The operation is extremely simple and fast, and it does not damage the PCB board 110 and the surface of the Mark point 120. At the same time, it has strong repeatability and controllable cost.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
