Technical Field

[0001] This utility model belongs to the field of DBC board cleaning technology, and in particular relates to a DBC cleaning fixture. Background Technology

[0002] DBC board, or ceramic-based copper-clad laminate, refers to a special process in which copper foil is directly bonded to the surface (single-sided or double-sided) of an alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate at high temperatures. The resulting ultra-thin composite substrate possesses excellent electrical insulation properties, high thermal conductivity, excellent solderability, and high adhesion strength. Like a PCB board, it can be etched with various patterns and has a large current-carrying capacity. Therefore, DBC substrates have become a fundamental material for high-power power electronic circuit structure and interconnection technologies.

[0003] After the DBC board is manufactured, it needs to be cleaned to remove surface impurities. Currently, the common method is to place the DBC board in a cleaning solution to clean it. However, this method cannot effectively improve the cleaning efficiency and the cleanliness of the DBC board. In addition, the process of immersing individual DBC boards in the cleaning solution and then taking them out is quite cumbersome. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-5 As shown, a DBC cleaning fixture includes:

[0030] Base 1, with several lower cleaning tanks 11 provided on base 1;

[0031] Loading platform 2, several loading platforms 2 are arranged in a linear array on the base 1. Each of the four corners of the loading platform 2 is provided with an installation groove. DBC plates are installed in the installation groove. Several water guide grooves 12 are also provided on the base 1. The water guide grooves 12 are located between adjacent loading platforms 2.

[0032] The upper cover plate 3, the base 1 and the upper cover plate 3 are equipped with several sets of fixing components 4, and the base 1 and the upper cover plate 3 are fixedly connected by the several sets of fixing components 4. Several upper cleaning grooves 31 are opened on the upper cover plate 3.

[0033] The upper cover plate 3 has several elastic columns 6 installed on the side facing the base 1. The lower end of the elastic column 6 elastically abuts against the DBC sheet installed in the mounting groove.

[0034] The fixing component 4 includes a buckle 41 and a buckle seat 42. The buckle 41 is fixed on the upper cover plate 3, and the buckle seat 42 is fixed on the base 1. The buckle 41 and the buckle seat 42 are fastened together to fix the base 1 and the upper cover plate 3.

[0035] Several sets of guide components 5 are installed between the base 1 and the upper cover plate 3. The guide components 5 include guide posts 51 and guide seats 52. The guide posts 51 are fixed on the upper cover plate 3, and the guide seats 52 are fixed on the base 1. The guide posts 51 are fitted inside the guide seats 52.

[0036] In practical application, several DBC boards are placed one by one into several mounting slots. Then, the operator holds the handle 33 to operate the top cover 3, guiding and positioning it by inserting the guide post 51 into the guide seat 52. The top cover 3 is then accurately positioned and secured by the buckle 41 fastening it to the buckle seat 42. Simultaneously, several elastic posts 6 elastically press against the DBC boards to prevent them from shaking during cleaning, which could affect cleaning efficiency or cause damage. During cleaning, the operator holds the handle 33 and immerses the entire fixture in the cleaning solution to clean the DBC boards. Alternatively, the entire fixture structure can be fixed. The DBC boards placed in the cleaning device are rinsed with cleaning fluid on the carrier, and multiple DBC boards can be cleaned at once, improving cleaning efficiency. Online equipment can be used to automatically position and fix the products, facilitating batch cleaning of DBC boards. The cleaning fluid flows through the lower cleaning tank 11, the water guide tank 12 and the upper cleaning tank 31 to clean the surface of the DBC boards, providing a more comprehensive cleaning and further improving the cleaning efficiency. Various cleaning methods such as ultrasonic cleaning, plasma cleaning and dry ice cleaning can be used to meet different needs. The fixture has a compact structure, is easy to manufacture and has strong practicality.

[0037] Furthermore, the mounting slot includes slot 1 21 and slot 2 22. Slot 1 21 and slot 2 22 are opened sequentially from the inside to the outside with reference to the loading platform 2. The top of slot 1 21 and slot 2 22 is a downward curved arc shape. Slot 1 21 and slot 2 22 are different in size.

[0038] In practical application, this embodiment uses slot 1 21 and slot 22 of different specifications to allow for the cleaning of two different specifications of DBC boards. The two different specifications of DBC boards can be placed in different slots for synchronous cleaning. Compared with the prior art, this eliminates the need to adjust the structural position, reduces adjustment time, and improves the cleaning efficiency of DBC boards.

[0039] The tops of slot 1 21 and slot 2 22 are curved downwards. When the DBC board is placed on several slots 1 21 or several slots 2 22, the four corners of the DBC board are locked. When the cleaning fluid flows from the lower cleaning tank 11 and the water guide tank 12, the elastic column 6 is elastic, and the cleaning fluid can push the DBC board up and down. Compared with the tops of slot 1 21 and slot 2 22 being flat, the cleaning fluid can clean the part of the bottom of the DBC board that was originally blocked, so that the DBC board is cleaned more thoroughly, thereby improving the cleaning effect of the DBC board.

[0040] like Figure 4 and Figure 6As shown, the bottom of the upper cover plate 3 has an active groove 32, and a slide plate 7 is symmetrically slidably installed in the active groove 32. A spring 8 is connected between one end of the slide plate 7 and the active groove 32. Several elastic columns 6 are fixedly installed on several slide plates 7. A connecting plate 71 is provided on several slide plates 7 on the same side. The connecting plate 71 is perpendicular to several slide plates 7. A rocking component 9 is installed on the side of the upper cover plate 3 away from the base 1. The rocking component 9 drives the slide plate 7 to move.

[0041] The swing assembly 9 includes a fixed shaft 91, which is fixedly installed on the upper cover plate 3. The fixed shaft 91 is parallel to the connecting plate 71. Several cams 92 are rotatably installed around the fixed shaft 91. Several touch plates 711 are provided on the connecting plate 71. The cams 92 rotate and squeeze the touch plates 711, causing the connecting plate 71 to drive several sliding plates 7 to move. A connecting rod 93 is connected between the cams 92. The connecting rod 93 is connected to the external hoisting equipment.

[0042] In practical application, this embodiment is connected to the connecting rod 93 via an external hoisting device. When the entire fixture structure is immersed in the cleaning solution, the hoisting device can appropriately shake the fixture structure, causing it to oscillate back and forth in the cleaning solution. This causes several cams 92 to repeatedly press several contact plates 711 on both sides. When the cams 92 press the contact plates 711, the contact plates 711 will drive several sliding plates 7 to slide within the movable groove 32 via the connecting plate 71. In this way, the sliding plates 7 will drive several elastic pillars 6 to move back and forth, thus preventing the elastic pillars 6 from always being in the same position on the DBC plate. This allows the cleaning solution to clean the original position where the elastic pillars 6 were in contact with the DBC plate, further cleaning the DBC plate more thoroughly and improving the cleaning effect. At the same time, the oscillation of the fixture structure in the cleaning solution allows for more comprehensive contact between the DBC plate and the cleaning solution, further improving the cleaning efficiency. To ensure that the reciprocating movement of the elastic pillars 6 does not damage the DBC plate, ball bearings can be installed at the end of the elastic pillars 6 that are in contact with the DBC plate.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
