[0032] The present application provides a substrate washing fixture, which includes a carrier plate 1, a carrier plate limiting frame 11, a first window structure 12, a first limiting device 13, a first limiting column 131, a support boss 132, a cover plate 2, a cover plate limiting frame 21, a second window structure 22, a second limiting module 23, a second limiting column 231, a strengthening column 232, and vulcanized rubber 3. A plurality of first mounting modules arranged in a grid pattern are provided on the carrier plate 1, and a plurality of second mounting modules arranged in a grid pattern are provided on the cover plate 2. The first mounting modules and the second mounting modules correspond to each other one by one. The carrier plate limiting frame 11 is distributed around the carrier plate 1, and the cover plate limiting frame 21 is distributed around the cover plate 2. The carrier plate 1 is fixedly connected to the cover plate 2 through the cooperation of the carrier plate limiting frame 11 and the cover plate limiting frame 21, so that the substrate is limited and fixed between the first mounting module and the second mounting module.

[0033] The first mounting module includes a first window structure 12 and a first limiting device 13. The first window structure 12 is arranged in a grid pattern, and the first limiting device 13 is located on the rib strips around the first window structure 12. The first limiting device 13 includes 8 first limiting columns 131 and 8 support bosses 132. The 8 first limiting columns 131 and the 8 support bosses 132 are distributed around the first window structure 12, and the inner side of the first limiting column 131 is connected to the corresponding support boss 132. Both the first limiting column 131 and the support boss 132 are wrapped with vulcanized rubber 3. The support boss 132 softly contacts and supports one surface of the substrate through the vulcanized rubber 3. The first limiting column 131 softly contacts the four sides of the substrate through the vulcanized rubber 3. The substrate is placed on a plurality of support bosses 132, and the movement of the substrate in the X and Y axial directions is restricted by the first limiting column 131.

[0034] The second mounting module includes a second window structure 22 and a second limiting module 23. The second window structure 22 is arranged in a grid pattern, and a second limiting module 23 is provided on the rib strips around the second window structure 22. The second limiting module 23 includes 4 second limiting columns 231 and 4 strengthening columns 232. Cover plate rib strips are provided around a plurality of second window structures 22. Both the second limiting column 231 and the strengthening column 232 are provided on the cover plate rib strips. The second limiting column 231 is located around the second window structure 22, and the strengthening column 232 is located at the middle position of one side of the second window structure 22 to strengthen the rib strength and prevent the rib from deforming. The second limiting column 231 and the strengthening column 232 are respectively wrapped with vulcanized rubber 3 for preventing scratching, bumping, and bruising. The strengthening column 232 softly contacts and supports the other surface of the substrate through the vulcanized rubber 3. And the second window structure 22 corresponds to the first window structure 12 one by one. Through the cooperation of the first limiting module 13 and the second limiting module 23, the substrate is limited between the first window structure 12 and the second window structure 22.

[0035] The first window structure 12 and the second window structure 22 are in regular or irregular shapes, and the four inner angles of the first window structure 12 and the second window structure 22 are respectively in the shape of an arc obtuse angle. The shapes of the first window structure 12 and the second window structure 22 are as large as possible so as to cover the entire working area of the printed circuit part on the substrate chip. Preferably, the width of each side length of the first window structure 12 and the second window structure 22 is appropriately reduced. While ensuring the large through-holes of the first window structure 12 and the second window structure 22 as much as possible, ensure that all interfaces are preferably in the structure of an arc obtuse angle. From the perspective of force and when cleaning with water flow or other fluids, firstly, it is to avoid impurities getting stuck at acute angles or sharp corners, causing accumulation; secondly, in terms of fluid mechanics, when the fluid passes through the arc-shaped structure, a vortex-shaped trajectory will be formed, and the force will not be so sharp, having a certain buffering effect or a repeated cleaning effect.

[0036] The first limiting post 131 and the second limiting post 231 are adaptively connected. The first limiting post 131 and the second limiting post 231 are in soft contact with the side of the substrate through the vulcanized rubber 3, and the first limiting post 131 and the second limiting post 231 limit the movement of the substrate in the X and Y axial directions; and the tops of the first limiting post 131 and the second limiting post 231 are conical, which is convenient for the manipulator clamping the substrate to place the substrate.

[0037] The supporting boss 132 and the strengthening post 232 are adaptively connected. The supporting boss 132 and the strengthening post 232 are in soft contact with the surface of the substrate through the vulcanized rubber 3 for supporting, preventing damage to the circuit, and limiting and fixing the substrate between the first window structure 12 and the second window structure 22. And the sum of the height of the supporting boss 132, the thickness of the substrate, and the height of the strengthening post 232 is equal to the distance between the upper surface of the carrier plate 1 and the lower surface of the cover plate 2, realizing the clamping of the substrate.

[0038] More specifically, the specific range of the hardness of the vulcanized rubber 3 can be defined between Shore hardness 60 - 80 (Shore60 - 80), and there should be no interference fit during clamping. The rubber has high toughness and is not easily damaged, broken or cracked during the processes of flushing and cleaning; the rubber has appropriate hardness, and the elastic rubber can protect the product from being bruised and scratched, etc.; the rubber has high stability and can ensure the long-term use of the rubber at a temperature of 90 °C; the rubber has an accurate dimensional range, that is, the rubber coating adopts a die-casting process and the thickness is stable.

[0039] During the cleaning process, after buckling the carrier plate 1 of the water washing fixture on the surface of the tray fixture and then flipping it, the substrate can be transitioned from the tray fixture into the carrier plate 1 of the water washing fixture. Secondly, buckle the cover plate 2 of the water washing fixture above its carrier plate 1 and then flip it. Finally, place the water washing fixture on the workbench to enter the cleaning process.
