Description

TECHNICAL FIELD

[0001] The utility model relates to an auxiliary device for ceramic substrate preparation, in particular to a flux sticking device. BACKGROUND

[0002] In the process of DPC ceramic substrate packaging, flux is usually used to make the packaging more compact.

[0003] In the prior art, a brush is usually used to evenly apply flux on the surface of the ceramic substrate or the welding point that needs to be welded, and the flux should be fully covered on the area that needs to be welded when applying. However, when using a brush or a sprayer to apply flux, the flux will not be evenly coated on the DPC ceramic substrate, resulting in a decrease in yield after welding is completed. SUMMARY

[0004] The main purpose of the utility model is to provide a flux sticking device, which changes the flux application method from brushing to sticking, and controls the depth of the flux groove to meet the needs of different DPC ceramic substrates, so as to make the flux coating uniform.

[0005] In order to achieve the above purpose, the utility model provides a flux sticking device, which comprises:

[0006] A workbench plate is provided with a square through hole;

[0007] A flux groove is provided, which comprises a first fixed block, a second fixed block and a third fixed block. The first fixed block and the third fixed block are fixedly connected with the workbench plate, and the first fixed block and the third fixed block are respectively located on the two sides of the length direction of the square through hole. The second fixed block is located between the first fixed block and the third fixed block, and the second fixed block is slidably connected with the first fixed block, the third fixed block and the workbench plate. The height of the second fixed block is lower than the height of the first fixed block, the third fixed block and the workbench plate, and the height of the first fixed block, the third fixed block and the workbench plate is on the same horizontal plane.

[0008] A moving device is located below the workbench plate, and the moving device can drive the second fixed block to rise or fall.

[0009] Preferably, the moving device comprises a driving motor, a screw pair, two guide rods, a top rod and a bracket. The bracket is fixedly connected with the workbench plate, the driving motor is fixedly installed on the bracket, the driving motor drives the screw pair to rotate, one end of each guide rod is slidably connected with the screw pair, the other end of one guide rod is fixedly connected with the bottom of the first fixed block, the other end of the other guide rod is fixedly connected with the bottom of the second fixed block, and the two ends of the top rod are respectively fixedly connected with the screw pair and the second fixed block.

[0010] Further preferably, the screw rod and the support are threadedly connected, one end of the screw rod is fixedly connected with the output end of the driving motor, the support is slidably connected with the guide rod, and the support is fixedly connected with the top rod.

[0011] Still further preferably, the support is oval-shaped, the two guide rods are symmetrically arranged at the long axis ends of the support, and the top rods are symmetrically arranged at the short axis ends of the support.

[0012] Further preferably, the support includes a support plate and support rods, the support plate is rectangular, and the support rods are fixedly arranged at the four corner positions of the support plate, and the top of each support rod is fixedly connected with the workbench plate.

[0013] The present application has the following advantages:

[0014] 1. Accurate control of the amount of flux:

[0015] By adjusting the height of the second fixed block, the amount of flux in the flux groove can be accurately controlled. At the same time, by controlling the height, the depth of the DPC ceramic substrate extending into the flux groove is avoided. This is crucial for DPC ceramic substrate packaging, as too much flux can cause welding quality problems such as short circuits or poor electrical connections, while too little flux can affect the reliability of the weld.

[0016] 2. Improve production efficiency:

[0017] The present application controls the lifting of the second fixed block through the moving device, especially through the cooperation of the driving motor, screw rod pair and guide rod, which can automatically adjust the height of the flux groove, thereby quickly adapting to different batches or different specifications of DPC ceramic substrates. This reduces manual intervention and improves production efficiency.

[0018] 3. Ensure welding quality:

[0019] Since the height of the flux groove can be accurately adjusted, it can be ensured that the flux is evenly and appropriately applied to the DPC ceramic substrate each time, which helps to form uniform and strong welding points, thereby improving the reliability and durability of the package.

[0020] 4. Easy to maintain and clean:

[0021] The design of the flux pickup device of the present application is relatively simple and modular, making it easier to maintain and clean.

[0022] 5. Strong adaptability:

[0023] The flux pickup device of the present application can adjust the size of the flux groove according to actual needs to adapt to DPC ceramic substrates of different sizes. BRIEF DESCRIPTION OF DRAWINGS
