Description

Technical Field

[0001] The utility model relates to the technical field of laser drilling equipment, in particular to a magnetic suction component platform for laser drilling of a ceramic copper-clad carrier plate. Background Art

[0002] Ceramic copper clad substrates are special materials that combine ceramic substrates and copper foil. They are widely used in the manufacture of electronic components due to their excellent heat dissipation, mechanical strength, conductivity and electrical connection properties, as well as high insulation and large current carrying capacity.

[0003] At present, when drilling holes in ceramic copper-clad substrates, laser drilling is usually used. Before drilling, the ceramic copper-clad substrate usually needs to be placed on the drilling station and fixed with a vacuum adsorption platform before subsequent laser drilling. However, due to the particularity of laser drilling, the contact part between the vacuum adsorption platform and the substrate is easily damaged by the laser during drilling, resulting in pits on the platform, which in turn causes foreign matter to remain in the pits, contaminating the next piece of material, and causing a series of problems such as uneven force on the ceramic copper-clad substrate after it is placed on the platform.

[0004] In view of the above problems, the existing solution is usually to design the vacuum adsorption platform into two parts, namely: a base part and a platform part, such as Figure 1 As shown, the bottom platform part and the platform part are detachably fixedly connected by bolts. After the vacuum adsorption platform is damaged, the platform part can be directly replaced. However, under the current high-frequency working state of drilling holes in the ceramic copper-clad substrate, the replacement frequency of the platform part is very high, and the platform part needs to be replaced every few days. The existing platform part includes a placement table part and a connection table part, which has a large dead weight. Frequent replacement is not only cumbersome and costly, but also has the risk of thread slippage. In addition, due to the need to frequently replace new platform parts, the horizontality of the top surface of the platform part after fastening with bolts is currently difficult to guarantee, which will affect the processing accuracy of the ceramic copper-clad substrate.

[0005] Based on the above background, the inventor has designed a magnetic suction component platform for laser drilling of ceramic copper-clad substrates, which can solve one or more of the above problems, and thus proposed the present application. Utility Model Content

[0006] The purpose of the present application is to provide a magnetic suction component platform for laser drilling of ceramic copper-clad substrates, so as to solve the problem of troublesome operation and high cost in replacing the platform part of the vacuum adsorption platform in the prior art.

[0009] Optionally, the four end surfaces of the adsorption top cover are provided with a top cover bottom edge extending vertically downward;

[0012] The bottom edge of the top cover and / or the connecting fence are made of magnetically friendly material.

[0013] Optionally, it also includes a connecting groove arranged at the top of the connecting fence;

[0024] Beneficial effects of the utility model:

[0025] The present application designs the original platform part into a magnetically connected component. On the one hand, after the top surface of the adsorption top cover of the present application is damaged due to laser drilling, the adsorption top cover can be removed and a new adsorption top cover can be replaced. Compared with the prior art, the operation of repeatedly tightening the connecting bolts during the operation of replacing the platform part in the original design is eliminated.

[0040] In this embodiment, the original platform part 2 is designed to be a magnetically connected component. On the one hand, after the top surface of the adsorption top cover 21 of the present application is damaged due to laser drilling, the adsorption top cover 21 can be removed and a new adsorption top cover 21 can be replaced. Compared with the prior art, the operation of repeatedly tightening the connecting bolts during the replacement of the platform part 2 in the original design is eliminated.

[0041] On the other hand, the present application only replaces the adsorption top cover 21 part in the platform part 2 assembly. The surface flatness of the other connecting platform 22 connected to the bottom part 1 does not directly affect the punching operation and effect of the ceramic copper-clad carrier board. Therefore, compared with the original design, the present application has the effect of saving material costs.

[0055] In this embodiment, refer to Figure 3 and Figure 4 As shown, the magnet member is a permanent magnet strip 26 fixedly connected to the top of the connecting fence 23. In this embodiment, the connecting groove 24 and the connecting protrusion 25 are both square ring-shaped. In this embodiment, four permanent magnet strips 26 are provided, which are respectively provided at the bottom of the four bottom edges of the square ring-shaped connecting groove 24.

[0056] In this embodiment, refer to Figure 5 As shown, a level installation structure is also provided on the side of the adsorption top cover 21. By providing the level installation structure, a level can be installed to facilitate the detection of the levelness of the top surface of the adsorption top cover 21, thereby ensuring the processing accuracy and effect.
