Description

Technical Field

[0001] The present invention relates to the field of high thermal conductivity material processing, and specifically to a cold pressing consolidation device for diamond high thermal conductivity composite powder. Background Art

[0002] With the miniaturization of electronic devices, the chip power density has also increased, and the heat dissipation requirements for electronic packaging materials have become more stringent. Therefore, advanced thermal management materials (high thermal conductivity, low thermal expansion) need to be used to effectively improve the stability and reliability of electronic devices. Electronic packaging materials have gone through the first generation of Invar and Kovar alloys; the second generation of tungsten-copper and molybdenum-copper alloys; the third generation of aluminum matrix composites reinforced with thermal conductive ceramic particles (elemental silicon, silicon carbide). Now, the fourth-generation technology uses diamond as the thermal conductive filler in aluminum and copper-based thermal conductive materials. With its advantages such as low price and rich reserves, diamond high thermal conductivity composite materials have been widely used in power devices, the electronics industry, aerospace, etc.

[0003] Vacuum hot pressing sintering is a traditional powder metallurgy method for preparing metal matrix composites. Its preparation process mainly includes screening, mixing, cold pressing consolidation, degassing, hot pressing sintering of metal powders and ceramic particles, etc., and then pressing to obtain aluminum matrix composites. However, in the prior art, when cold pressing and consolidating diamond high thermal conductivity composite powder, the molding device can only mold one production part each time, with low processing efficiency. When it comes to the molding of production parts, a large number of cold pressing consolidation devices for electronic components need to be moved and reset, with a complex structure and high cost. Moreover, there is no subsequent step for transferring the production parts after the production parts are processed and formed. In individual laboratories when processing small batches of production parts, they even need to rely on manual clamping of the production parts for transfer. Therefore, it is necessary to design a cold pressing consolidation device for diamond high thermal conductivity composite powder, which is low-cost, can realize the processing and transfer of production parts through mechanical linkage, and is suitable for the small batch and multi-quantity production mode for laboratory testing.

[0041] Refer to Figures 1 to 15 , the cold pressing consolidation equipment for diamond high thermal conductivity composite material powder, comprising:

[0042] A molding mechanism 1, which can cold press and form the composite material powder;

[0043] A power mechanism 2, arranged beside the molding mechanism 1, and the power mechanism 2 can provide power for the movement of the working position during the cold pressing consolidation of the composite material;

[0044] A supporting component 7, movably arranged at the upper end of the power mechanism 2, and the supporting component 7 includes a plurality of lifting and pulling-back mechanisms 9, and the number of the plurality of lifting and pulling-back mechanisms 9 corresponds to the number of cold pressing consolidations of the composite material;

[0045] A scraping component 24, arranged in the middle of the power mechanism 2, and the scraping component 24 includes two first spring-back mechanisms 29 and two second spring-back mechanisms 34, and the two first spring-back mechanisms 29 are respectively arranged above the two second spring-back mechanisms 34;

[0046] Two stopping mechanisms 39, symmetrically arranged below the supporting component 7.

[0047] The molding mechanism 1 includes a molding machine 53, a blanking swing rod 54, a power motor 55, and a power rotating shaft 56. The molding machine 53 is arranged above the power mechanism 2. The output end of the power motor 55 is vertically upward and arranged on the side of the molding machine 53 away from the power mechanism 2. The power rotating shaft 56 is fixedly axially connected to the output end of the power motor 55. The blanking swing rod 54 is fixedly arranged at the upper end of the power rotating shaft 56, and the middle part of the blanking swing rod 54 is fixedly sleeved with the power rotating shaft 56. Before the device runs, the operator puts the powder for cold pressing consolidation into the device. Then the device runs. When the powder for cold pressing consolidation moves to the lower part of the molding machine 53, the molding machine 53 presses down to form the powder into a shape. Then the power motor 55 starts. The power rotating shaft 56 is fixedly connected to the output end of the power motor 55, and the middle part of the blanking swing rod 54 is fixedly sleeved with the power rotating shaft 56. The rotation of the power motor 55 will drive the blanking swing rod 54 to rotate. At this time, the finished product that is automatically demolded (the process of automatic demolding will be explained later) will be automatically scraped off by the rotating blanking swing rod 54. At this time, the production of the product finished product is completed.

[0048] The power mechanism 2 includes a support base 3, a power cylinder 4, a sliding support seat 6, and several support sliders 5. The supporting component 7 further includes a mounting base 8, a supporting top plate 20, and a collecting box 23. Among them, the support base 3 is fixedly arranged under the molding machine 53. The power cylinder 4 is arranged on the side of the support base 3 away from the molding machine 53. The power cylinder 4 is fixedly connected to the upper end of the support base 3. Several support sliders 5 are equidistantly and fixedly arranged on the upper end of the support base 3. The sliding support seat 6 is arranged on the upper end of the support sliders 5. The sliding support seat 6 is slidably connected to the support sliders 5. One end of the sliding support seat 6 close to the power cylinder 4 is fixedly connected to the output end of the power cylinder 4. The mounting base 8 is fixedly arranged on the upper end of the sliding support seat 6. The supporting top plate 20 is arranged above the mounting base 8. The collecting box 23 is fixedly arranged at one end of the supporting top plate 20 close to the power cylinder 4. When the powder of the composite material is placed in place, the power cylinder 4 starts. The output end of the power cylinder 4 is fixedly connected to the sliding support seat 6. The start of the power cylinder 4 will push the sliding support seat 6 to move reciprocally. The sliding support seat 6 is slidably connected to the support sliders 5. During the movement of the sliding support seat 6, the scraping component 24 will scrape off the excess powder, and the scraped powder will finally fall into the collecting box 23.

[0049] A number of lifting and pulling-back mechanisms 9 each include a finger cylinder 10, a bearing base 11, a limit sleeve 17, a core 18, a connecting sleeve 19, and four auxiliary spring-back devices 12. A number of avoidance holes 21 and two blanking chutes 22 are formed on the supporting top plate 20. The number of avoidance holes 21 corresponds one-to-one with the number of finger cylinders 10. The two blanking chutes 22 are distributed along the two long sides of the supporting top plate 20. The finger cylinder 10 is fixedly embedded with the mounting base 8. The bearing base 11 is arranged at the upper end of the finger cylinder 10, and the bearing base 11 is fixedly connected with the mounting base 8. The limit sleeve 17 is arranged at the upper end of the bearing base 11. The core 18 is coaxially arranged inside the limit sleeve 17. The lower end of the core 18 is fixedly connected with the output end of the finger cylinder 10. The four auxiliary spring-back devices 12 are equally spaced outside the limit sleeve 17. The four auxiliary spring-back devices 12 can assist the core 18 to spring back to the initial position. The connecting sleeve 19 is coaxially sleeved on the upper end of the limit sleeve 17. The connecting sleeve 19 is slidably connected with the limit sleeve 17. The upper end of the connecting sleeve 19 is fixedly connected with the supporting top plate 20. When the device operates: When the powder of the composite material is pressed and formed, the finished product needs to be pushed out upward and scraped off by the blanking swing rod 54. At this time, the finger cylinder 10 operates. The bearing base 11 is fixedly connected with the output end of the finger cylinder 10. The operation of the finger cylinder 10 can drive the bearing base 11 to move upward. The limit sleeve 17 is slidably connected with the connecting sleeve 19. When the output end of the finger cylinder 10 reaches the maximum value, the finished product will be completely located at the upper end of the supporting top plate 20, that is, at this time, the finished product will be scraped off by the blanking swing rod 54. The core 18 and the limit sleeve 17 cooperate to mold the shape of the finished product. The four auxiliary spring-back devices 12 can assist the finger cylinder 10 to spring back and prevent the device from jamming.

[0050] Each auxiliary spring-back device 12 includes a movable short pin 13, an auxiliary spring 14, a linear bearing 15, and a fixed gasket 16. The upper end of the movable short pin 13 is fixedly connected with the connecting sleeve 19. The upper end of the auxiliary spring 14 abuts against the lower end of the movable short pin 13. The lower end of the auxiliary spring 14 abuts against the upper end of the bearing base 11. The linear bearing 15 is coaxially sleeved outside the movable short pin 13. The linear bearing 15 is slidably connected with the movable short pin 13. The lower end of the linear bearing 15 is fixedly inserted into the bearing base 11. The fixed gasket 16 is coaxially sleeved outside the linear bearing 15. The fixed gasket 16 is fixedly connected with the upper end of the bearing base 11. When the auxiliary spring-back device 12 operates, the movable short pin 13 will move. The upper end of the auxiliary spring 14 abuts against the movable short pin 13, and the lower end of the auxiliary spring 14 abuts against the bearing base 11. That is, as the movable short pin 13 moves, the auxiliary spring 14 will be compressed. When the device needs to return to its original position, the compressed auxiliary spring 14 will recover its deformation. At this time, the finger cylinder 10 can accelerate the reset and prevent the device from jamming. The linear bearing 15 is used to provide a limit for the movement of the movable short pin 13.

[0051] The scraping component 24 includes a scraping plate 27 and two limiting slide bars 25. The two limiting slide bars 25 are fixedly arranged on both sides of the long side of the supporting top plate 20. Oblique guide rails 26 are formed on both of the two limiting slide bars 25. The scraping plate 27 is arranged at one end of the supporting top plate 20 away from the power cylinder 4. The first elastic return mechanism 29 includes a lifting bracket 30, a scraping short pin 31, a scraping sleeve 32 and a return torsion spring 33. The two lifting brackets 30 are respectively arranged on both sides of the supporting base 3. The scraping short pin 31 is arranged in a horizontal state. The scraping short pin 31 is fixedly inserted into the upper end of the lifting bracket 30. The scraping sleeve 32 is fixedly arranged on the side of the scraping short pin 31 away from the supporting base 3. Both ends of the scraping plate 27 are rotatably connected to the two scraping sleeves 32. The return torsion springs 33 are arranged at both ends of the scraping plate 27. One end of each return torsion spring 33 is fixedly inserted into the scraping sleeve 32, and the other end is fixedly inserted into the scraping plate 27. When the supporting top plate 20 moves below the molding machine 53 through the scraping plate 27, the powder above the supporting top plate 20 will be scraped off by the scraping plate 27 at this time. After the scraping plate 27 scrapes off the powder, the two return torsion springs 33 can assist the scraping plate 27 to return to its original position, so that the scraping plate 27 can spontaneously scrape off the excess powder above the supporting top plate 20. The scraping short pin 31 and the scraping sleeve 32 can determine the specific height of the scraping plate 27 to prevent the scraping plate 27 from colliding with the supporting top plate 20. During the scraping process, the blanking chute 22 can ensure that the powder does not scatter everywhere.

[0052] The second elastic return mechanism 34 includes a fixed base 35, a compression spring 36, a support sleeve 37 and a limiting ball head 38. The fixed base 35 is arranged below the scraping short pin 31. The fixed base 35 is fixedly connected to the lifting bracket 30. The support sleeve 37 is fixedly sleeved outside the fixed base 35. The compression spring 36 is arranged inside the support sleeve 37. The limiting ball head 38 is slidably inserted into the support sleeve 37. One end of the compression spring 36 abuts against the fixed base 35, and the other end abuts against the limiting ball head 38. When the supporting top plate 20 moves below the molding machine 53 through the scraping plate 27, the oblique guide rail 26 will cooperate with the limiting ball head 38. At this time, the limiting ball head 38 will move along the oblique guide rail 26 in the direction close to the lifting bracket 30, and the supporting top plate 20 will move upward. The upward moving supporting top plate 20 not only facilitates the molding machine 53 to mold the powder, but also facilitates the scraping plate 27 to scrape off the excess powder. And during the movement, the end of the limiting ball head 38 away from the oblique guide rail 26 abuts against the compression spring 36, then the compression spring 36 will be compressed at this time. When the supporting top plate 20 returns from below the molding machine 53 through the scraping plate 27, the limiting ball head 38 will return along the original track of the oblique guide rail 26, which is convenient for the next molding work to be carried out.

[0053] The stop mechanism 39 includes a mounting square tube 40, a linkage square block 44, a linkage top plate 51, a linkage short rod 47, two linkage connecting rods 52, two linkage short pins 42, two linkage springs 43, two moving gaskets 48, two linkage gaskets 49 and two linkage tension springs 50. The mounting square tube 40 is arranged vertically and is fixedly connected to the mounting base 8. The two linkage short pins 42 are fixedly arranged inside the mounting square tube 40. The two linkage springs 43 are coaxially sleeved outside the linkage short pins 42. Two linkage chutes 45 are also formed inside the mounting square tube 40. The linkage square block 44 is arranged inside the mounting square tube 40. The linkage square block 44 is slidably connected to the mounting square tube 40 through the two linkage chutes 45 and is slidably connected to the two linkage short pins 42. The upper ends of the two linkage tension springs 50 abut against the lower end of the linkage square block 44, and the lower ends of the two linkage tension springs 50 abut against the pin caps of the two linkage short pins 42. The two moving gaskets 48 are fixedly arranged on the upper end of the linkage square block 44. The linkage top plate 51 is fixedly arranged at the upper end of the mounting square tube 40. The two linkage gaskets 49 are arranged at the lower end of the linkage top plate 51. One end of each of the two linkage tension springs 50 is fixedly connected to the moving gasket 48, and the other end is fixedly connected to the moving gasket 48. The lower end of the linkage short rod 47 is fixedly connected to the upper end of the linkage square block 44, and the upper end of the linkage short rod 47 is fixedly connected to the supporting top plate 20. At the same time, the linkage short rod 47 is also slidably connected to the linkage top plate 51. Two stop chutes 46 are formed at both ends of the linkage square block 44. The two linkage connecting rods 52 are hinged to the mounting square tube 40 at one end and are slidably connected to the stop chutes 46 at the other end. During the powder cold pressing consolidation process, in order to ensure that the supporting top plate 20 can perform vertical displacement as it moves horizontally, when the inclined guide rail 26 cooperates with the limit ball head 38, when the supporting top plate 20 moves downward, at this time, the linkage short rod 47 is fixedly connected to the supporting top plate 20. The downward movement of the supporting top plate 20 will drive the linkage short rod 47 to move. The linkage square block 44 is fixedly connected to the linkage short rod 47, and the movement of the linkage square block 44 will drive the linkage square block 44 to move. The linkage square block 44 is slidably connected to the mounting square tube 40 through the linkage chute 45. Then, when the linkage square block 44 moves downward, the two linkage springs 43 located at the lower end of the linkage square block 44 will be compressed, and the two linkage tension springs 50 located at the upper end of the linkage square block 44 will be stretched. At this time, the ends of the two linkage connecting rods 52 connected to the stop chutes 46 will move in the stop chutes 46 and will eventually get stuck at the upper end of the braking chute. When the supporting top plate 20 moves upward, similarly, at this time, the two linkage springs 43 and the two linkage tension springs 50 will reset, that is, the ends of the two linkage connecting rods 52 connected to the stop chutes 46 will continue to move in the stop chutes 46, and finally, the two linkage connecting rods 52 complete a cycle of movement and return to the initial position at the lower end.

[0054] The working principle of this device is as follows: Before the device operates, the operator puts the powder for cold pressing consolidation into the limit sleeve 17. Subsequently, when the device operates, when the powder for cold pressing consolidation moves below the molding press 53, the molding press 53 presses down to form the powder into a shape. Then, the power motor 55 starts. The power rotating shaft 56 is fixedly connected to the output end of the power motor 55. The middle part of the demolding swing rod 54 is fixedly sleeved with the power rotating shaft 56. The rotation of the power motor 55 will drive the demolding swing rod 54 to rotate. At this time, the finished product that is automatically demolded (the process of automatic demolding will be explained later) will be automatically scraped off by the rotating demolding swing rod 54. At this time, the production of the product is completed. When the powder of the composite material is placed in place, the power cylinder 4 starts. The output end of the power cylinder 4 is fixedly connected to the sliding support seat 6. The start of the power cylinder 4 will push the sliding support seat 6 to move reciprocally. The sliding support seat 6 is slidably connected to the support slider 5. During the movement of the sliding support seat 6, the scraping assembly 24 will scrape off the excess powder, and the scraped powder will eventually fall into the aggregate box 23.

[0055] After the powder of the composite material is pressed into shape, the finished product needs to be ejected upward and scraped by the stripping swing rod 54. At this time, the finger cylinder 10 operates. The bearing base 11 is fixedly connected to the output end of the finger cylinder 10. The operation of the finger cylinder 10 can drive the bearing base 11 to move upward. The limit sleeve 17 is slidably connected to the connecting sleeve 19. When the output end of the finger cylinder 10 reaches the maximum value, the finished product will be completely located above the supporting top plate 20, that is, at this time, the finished product will be scraped by the stripping swing rod 54. The core mold 18 and the limit sleeve 17 cooperate to mold the shape of the finished product. The four auxiliary springback devices 12 can assist the finger cylinder 10 to spring back to prevent the device from jamming. When the auxiliary springback device 12 operates, the movable short pin 13 will move. The upper end of the auxiliary spring 14 abuts against the movable short pin 13, and the lower end of the auxiliary spring 14 abuts against the bearing base 11. That is, as the movable short pin 13 moves, the auxiliary spring 14 will be compressed. When the device needs to return to its original position, the compressed auxiliary spring 14 will restore its deformation. At this time, the finger cylinder 10 can accelerate the reset to prevent the device from jamming. The linear bearing 15 is used to limit the movement of the movable short pin 13. When the supporting top plate 20 moves to the lower part of the molding machine 53 through the scraping plate 27, the powder above the supporting top plate 20 will be scraped off by the scraping plate 27. After the scraping plate 27 scrapes off the powder, the two reset torsion springs 33 can assist the scraping plate 27 to reset, so that the scraping plate 27 can spontaneously scrape off the excess powder above the supporting top plate 20. The scraping short pin 31 and the scraping sleeve 32 can determine the specific height of the scraping plate 27 to prevent the scraping plate 27 from colliding with the supporting top plate 20. During the scraping process, the blanking chute 22 can ensure that the powder will not fly around. When the supporting top plate 20 moves to the lower part of the molding machine 53 through the scraping plate 27, the inclined guide rail 26 will cooperate with the limit ball head 38. At this time, the limit ball head 38 will move along the inclined guide rail 26 in the direction close to the lifting bracket 30, and the supporting top plate 20 will move upward. The upward moving supporting top plate 20 is not only convenient for the molding machine 53 to mold the powder, but also convenient for the scraping plate 27 to scrape off the excess powder. And during the movement, the end of the limit ball head 38 away from the inclined guide rail 26 abuts against the compression spring 36, then at this time, the compression spring 36 will be compressed. When the supporting top plate 20 is reset from the lower part of the molding machine 53 through the scraping plate 27, the limit ball head 38 will reset along the original track of the inclined guide rail 26, which is convenient for the next molding work to be carried out.During the cold pressing consolidation process of the powder, in order to ensure that the supporting top plate 20 can displace in the vertical direction as it moves horizontally, when the inclined guide rail 26 cooperates with the limit ball head 38, when the supporting top plate 20 moves downward, at this time, the linkage short rod 47 is fixedly connected to the supporting top plate 20. The downward movement of the supporting top plate 20 will drive the linkage short rod 47 to move. The linkage square block 44 is fixedly connected to the linkage short rod 47. The movement of the linkage square block 44 will drive the linkage square block 44 to move. The linkage square block 44 is slidably connected to the installation square pipe 40 through the linkage sliding groove 45. Then, when the linkage square block 44 moves downward, the two linkage springs 43 located at the lower end of the linkage square block 44 will be compressed, and the two linkage tension springs 50 located at the upper end of the linkage square block 44 will be stretched. At this time, one end of the two linkage connecting rods 52 connected to the stop sliding groove 46 will move in the stop sliding groove 46 and finally get stuck at the upper end of the braking sliding groove. When the supporting top plate 20 moves upward, similarly, at this time, the two linkage springs 43 and the two linkage tension springs 50 will return to their original positions, that is, one end of the two linkage connecting rods 52 connected to the stop sliding groove 46 will continue to move in the stop sliding groove 46. Finally, the two linkage connecting rods 52 complete a cycle of movement and return to the initial position at the lower end.
