Description

Technical Field

[0001] This utility model relates to the field of hot pressing technology, and in particular to a hot pressing apparatus for aluminum nitride substrates. Background Technology

[0002] Aluminum nitride ceramic substrates are electronic ceramic substrates with specific functions and structures made from aluminum nitride (AlN) ceramic as the base material. They are widely used in electronic packaging, power devices and other fields. Silicon nitride ceramic substrates require a hot pressing process during processing. Typically, three layers of blank material are used for hot pressing: upper cover material, substrate material and lower cover material.

[0003] In the published patent document 202421133481.9, this utility model relates to a hot pressing molding apparatus for the production of silicon nitride substrates, particularly in the technical field of electronic component material preparation. It includes a first drive cylinder, a pressure plate, a mold box, a heat preservation mechanism, a moving plate, a lifting mechanism, a second drive cylinder, a push plate, and a material collection mechanism. It overcomes the problems of heat loss due to the lack of a heat preservation structure in the hot pressing apparatus, and the waste of human resources caused by the fact that the scraped powder is usually not recovered after scraping the mold surface, or is collected manually.

[0004] When the above devices are in use, they realize the automatic recycling of waste materials by setting up push plates and material collection mechanisms. However, when the push plates push a large amount of material, the material at the edges is prone to accumulate too high and overflow from both sides, scattering into the workbench or inside the equipment. This not only causes material waste but may also cause equipment failure. Therefore, this application proposes a hot pressing forming device for aluminum nitride substrates. Utility Model Content

This invention proposes a hot pressing forming device for aluminum nitride substrates.

[0006] The technical solution of this utility model is as follows: A hot pressing forming device for aluminum nitride substrates includes a support frame, a connecting plate fixedly connected to the support frame, and an extrusion box and a waste box connected to the bottom of the connecting plate; a pressure plate is provided on the support frame, and the pressure plate is located at the top of the extrusion box; a collection box for cleaning excess material on the connecting plate is slidably installed on the connecting plate, two inclined guide plates are fixedly connected to the inlet of the collection box, one end of the guide plate is slidably connected to the support frame, and multiple rubber blocks are fixedly connected to the side of the guide plate near the support frame; multiple connecting rods are fixedly connected between the two guide plates; a vibration motor is fixedly connected to the collection box; and a shovel plate and an opening and closing plate that can be opened and closed in linkage are provided at the bottom of the collection box.

[0007] Optionally, a telescopic cylinder is fixedly connected to the bottom of the bracket, the connecting plate is fixedly connected to the extrusion box, a support plate is slidably connected inside the extrusion box, and the piston rod of the telescopic cylinder is fixedly connected to the support plate.

Two electric telescopic rods are fixedly connected to the top of the bracket, and the electric telescopic rods are fixedly connected to the connecting rod.

[0012] Optionally, the rubber block is provided with raised particles.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] This invention utilizes the structural design of the collection box and rubber block. When the collection box moves to collect materials, the rubber block and the support generate frictional vibration, which in turn vibrates the guide plate and connecting rod. Through the rigidly connected connecting rod assembly, the vibrational energy is effectively transferred to the inclined guide plate, thereby breaking down the cohesive force and static friction force formed on the surface of the guide plate. This ensures that the material remains in a loose flow state under the action of gravity, preventing material overflow and waste, and avoiding pollution of the working environment.

[0015] This utility model discloses a hot pressing molding device for aluminum nitride substrates. By using a collection box and rubber blocks, the device vibrates the material during collection to keep it in a dispersed flow state, preventing material overflow and waste, reducing material pollution to the working environment, and improving the stability and reliability of the material collection and transportation process.

[0023] like Figure 1As shown, a hot pressing forming device for aluminum nitride substrates includes a support 1, a connecting plate 2 fixedly connected to the support 1, an extrusion box 3 and a waste box 4 connected to the bottom of the connecting plate 2, and the waste box 4 detachably installed on the connecting plate 2. The support 1 has a threaded groove, and the waste box 4 is threadedly connected to the threaded groove by bolts. The waste box 4 can be installed and removed by rotating the bolts, which facilitates regular cleaning and waste recycling, realizes resource recycling, prevents the box from being blocked due to waste accumulation, and ensures the continuous and stable operation of the collection system.

[0024] like Figure 1 and Figure 2 As shown, a pressure plate 11 is provided on the support 1, and the pressure plate 11 is located at the top of the extrusion box 3. A multi-stage cylinder 12 is fixedly connected to the top of the support 1, and the piston rod of the multi-stage cylinder 12 is fixedly connected to the pressure plate 11. The multi-stage cylinder 12 pushes the pressure plate 11 to press down, and the material in the extrusion box 3 is hot-pressed and formed. A telescopic cylinder 5 is fixedly connected to the bottom of the support 1, and a connecting plate 2 is fixedly connected to the extrusion box 3. A support plate 301 is slidably connected inside the extrusion box 3. The piston rod of the telescopic cylinder 5 is fixedly connected to the support plate 301. The pressure plate 11 extrudes and forms the material in the extrusion box 3. The telescopic cylinder 5 drives the support plate 301 to descend, realizing a stepped layered compaction process, ensuring uniform compression of the material and improving the forming density. After extrusion, the telescopic cylinder 5 pushes the support plate 301 to push the substrate out of the extrusion box 3 for collection.

[0025] like Figure 1 , Figure 2 As shown, a collection box 9 for cleaning excess material on the connecting plate 2 is slidably installed on the connecting plate 2. A stepper motor 6 is fixedly connected to one end of the bracket 1. A threaded screw 7 is rotatably connected to the bracket 1. A positioning rod 8 is fixedly connected to the bracket 1. The output shaft of the stepper motor 6 is fixedly connected to the threaded screw 7. The collection box 9 is threadedly connected to the threaded screw 7. The collection box 9 is slidably connected to the positioning rod 8. The collection box 9 is located between the positioning rod 8 and the threaded screw 7. When the stepper motor 6 is started, it drives the threaded screw 7 to rotate, causing the collection box 9 to slide on the connecting plate 2 to collect excess material on the connecting plate 2, preventing uneven molding pressure caused by material accumulation, which would affect the product quality during hot pressing.

[0026] like Figure 1 , Figure 3As shown, two inclined guide plates 10 are fixedly connected to the feed inlet of the collection box 9. One end of the guide plate 10 is slidably connected to the support 1. Multiple rubber blocks 1002 are fixedly connected to the side of the guide plate 10 near the support 1. Multiple connecting rods 1001 are fixedly connected between the two guide plates 10. A vibration motor 901 is fixedly connected to the collection box 9. The rubber blocks 1002 are provided with protruding particles. Vibration is generated by friction with the support 1, which drives the guide plate 10 and the connecting rods 1001 to vibrate, so that the material keeps the material fluid and avoids local accumulation, which would cause the material to overflow onto the worktable and cause pollution to the working environment.

[0027] like Figure 1 , Figure 4 As shown, the bottom of the collection box 9 is equipped with a shovel plate 13 and an opening / closing plate 14 that can be opened and closed in a linkage manner. The bottom of the collection box 9 is hinged to the shovel plate 13 and the opening / closing plate 14, with the shovel plate 13 and the opening / closing plate 14 fitting together. Two first transmission rods 1301 are hinged to the shovel plate 13, and two second transmission rods 1401 are hinged to the opening / closing plate 14. The first transmission rods 1301 and the second transmission rods 1401 are fixedly connected, and a connecting rod 15 is fixedly connected between the two second transmission rods 1401. The top of the bracket 1 is fixedly connected to... There are two electric telescopic rods 16, which are fixedly connected to the connecting rod 15. When the electric telescopic rods 16 extend, they push the connecting rod 15 down, causing the first transmission rod 1301 and the second transmission rod 1401 to move down and separate the shovel plate 13 from the opening and closing plate 14, allowing the material in the collection box 9 to fall into the waste box 4 for collection. After falling, the vibration motor 901 starts to vibrate and clean the collection box 9, preventing material from being stored in the dead corners of the collection box 9 and improving its practicality.

[0028] In this embodiment, after the material is fed into the extrusion box 3, the stepper motor 6 starts and drives the threaded screw 7 to rotate, causing the collection box 9 to move. During the movement, the rubber block 1002 on the guide plate 10 generates frictional vibration with the support 1. The vibration force is transmitted through the connecting rod 1001, which breaks the cohesive force and static friction force formed on the surface of the guide plate 10 by the material, ensuring that the material continues to maintain a loose flow state under the action of gravity, preventing the material from overflowing. After collection, the material is moved to the top of the waste bin 4. The electric telescopic rod 16 pushes the connecting rod 15 to press down the first transmission rod 1301 and the second transmission rod 1401, causing the shovel plate 13 and the opening and closing plate 14 to separate and open, allowing the material in the collection box 9 to fall into the waste bin 4 for recycling. The vibration motor 901 starts. The system vibrates the collection box 9 to clean it and prevent materials from accumulating in dead corners. After cleaning, the electric telescopic rod 16 drives the connecting rod 15 to reset, the stepper motor 6 starts, and the collection box 9 resets. The multi-stage cylinder 12 pushes the pressure plate 11 to hot-press the material in the extrusion box 3. After the material is formed, the telescopic cylinder 5 drives the support plate 301 to descend and continue to transport the material into the extrusion box 3. This process is repeated to perform multi-layer extrusion and shape the material. The collection box and rubber block vibrate the material during collection to keep it in a dispersed flow state, preventing material overflow and waste, reducing pollution to the working environment, and improving the stability and reliability of the material collection and transportation process.
