Description

Technical Field

[0001] The present application relates to the technical field of material feeding, and in particular to an inverted resin powder feeding device. Background Art

[0002] Resin powder used for semiconductor packaging is a high-performance material with good mechanical properties, chemical stability and electrical properties. It can effectively improve the heat dissipation and electrical properties of packaged devices, while enhancing shock resistance and moisture resistance. It is an important material in the field of semiconductor packaging.

[0003] Referring to the patent document with publication number CN107914355A, a resin material supply device includes an original supply part, an original supply part excitation part, a resin material holding part, an excitation part, a metering part, a groove, a tray and a moving mechanism. The resin powder is stored in the original supply part. The original supply part excitation part drives the original supply part to vibrate, so that the resin powder in the original supply part is transported to the resin material holding part. The excitation part drives the resin material holding part and the groove to vibrate, so that the resin powder is transported on the groove and sprinkled into the tray from the discharge port at the end of the groove. The moving mechanism drives the tray to move in the horizontal direction, so that the resin powder can be evenly sprinkled in the tray. The metering part is installed below the resin material holding part and measures the weight of the resin material holding part and the groove, so that the resin powder supply amount is more accurate.

[0004] Since the excitation part and the metering part are installed below the resin material holding part, the moving mechanism needs to drive the tray to move in the horizontal direction. Therefore, when the length of the slot is shorter, the distance the resin powder is transported in the slot is shorter, so that the accuracy of the resin powder supply will be higher. Due to the short length of the slot, the tray needs to be placed below the metering part before it can move in the horizontal direction. At this time, the height difference between the discharge port of the slot and the tray is large, and the resin powder is easy to splash out of the tray when it falls on the tray, thereby reducing the accuracy of the resin powder supply; when the length of the slot is longer, the tray can be placed below the slot. At this time, the height difference between the discharge port of the slot and the tray is smaller, and the resin powder will not bounce and splash when it falls on the tray, but the longer length of the slot will make the transportation distance of the resin powder longer, which will also reduce the accuracy of the resin powder supply.

[0022] By adopting the above-mentioned technical scheme, when the sealing door slides downward and separates the first warehouse body and the second warehouse body, the sealing door drives the two dividing plates to move downward, and when the bottom end of the dividing plate abuts the bottom wall of the inner cavity of the second warehouse body, the sealing door continues to move downward and will drive the two dividing plates to move away from each other through the sliding groove and the sliding block. The two dividing plates separate the resin powder during the movement, so that after the sealing door moves downward, the first sealing strip can abut against the bottom wall of the inner cavity of the second warehouse body, thereby improving the sealing and separation effect of the sealing door, and when the sealing door moves upward, the elastic reset part pulls the two dividing plates to move toward each other.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The second vibrating part and the weighing part are both located above the feeding plate, so that the feeding plate can be installed at the bottom of the inner cavity of the chassis. When the feeding end of the feeding plate extends out of the chassis for a short length, the height difference between the feeding end of the feeding plate and the tray is reduced, thereby improving the accuracy of the resin powder supply;

[0043] The first vibrating part 2 is installed on one side of the inner cavity of the chassis 50, a bracket 16 is fixedly installed on the top of the first vibrating part 2, and the silo 1 is fixedly installed on the top wall of the bracket 16. A feed port is formed on the top of the silo 1, and a discharge port is formed on the side of the silo 1.

[0044] The weighing part 7 is fixedly mounted on the other side of the inner cavity of the chassis 50 away from the first vibrating part 2, the second vibrating part 6 is mounted below the weighing part 7 through the connecting part 9, and the feeding plate 4 is detachably fixedly mounted on the bottom end of the second vibrating part 6. The feeding plate 4 is mounted in a horizontal direction, and the feeding plate 4 is located at the bottom of the inner cavity of the chassis 50.

[0045] The hopper 3 is fixedly mounted on the top of the feeding plate 4 near the side of the silo 1, and a support plate 24 is fixedly mounted on the inner wall of the chassis 50 near the weighing part 7 in the horizontal direction, and a guide bucket 25 is fixedly mounted on the end of the support plate 24 in the vertical direction. The top diameter of the guide bucket 25 is larger than the bottom diameter, the top end of the guide bucket 25 is located directly below the discharge port of the silo 1, and the bottom end of the guide bucket 25 is located directly above the hopper 3.

[0046] A feeding trough 5 is formed in the feeding plate 4 along its length direction, and the bottom of the hopper 3 is connected to the feeding trough 5. The end of the feeding plate 4 away from the hopper 3 is a discharge end, and the discharge end of the feeding plate 4 passes through the chassis 50 and extends to the outside of the chassis 50. The bottom of the discharge end of the feeding plate 4 is formed with a discharge port connected to the feeding trough 5.

[0047] Reference Figure 4 The tray 8 is mounted on the translation mechanism, the tray 8 is located below the chassis 50, and the tray 8 is located below the discharge end of the feeding plate 4. The translation mechanism is composed of two linear modules, and the translation mechanism can drive the tray 8 to move freely in the horizontal direction.

[0048] The resin powder is poured into the silo 1 through the feed port, and the first vibrating part 2 drives the hopper 3 to vibrate, so that the resin powder in the hopper 3 is transported out from the discharge port, and the resin powder transported out of the discharge port of the silo 1 falls into the hopper 3 through the guide bucket 25. The second vibrator drives the feed plate 4 and the hopper 3 to vibrate, and the resin powder in the hopper 3 enters the feed trough 5 of the feed plate 4, and the resin powder falls from the discharge port of the discharge end of the feed plate 4 to the tray 8 through the feed trough 5. The translation mechanism drives the tray 8 to move in the horizontal direction, so that the resin powder can be evenly spread in the tray 8, and the weighing part 7 weighs the supply amount of the resin powder, so that the supply amount of the resin powder is more accurate.

[0049] The second vibrating part 6 and the weighing part 7 are both located above the feeding plate 4, so that the feeding plate 4 can be installed at the bottom of the inner cavity of the chassis 50. When the discharge end of the feeding plate 4 extends out of the chassis 50 for a short length, the height difference between the discharge end of the feeding plate 4 and the tray 8 is also reduced, thereby improving the accuracy of the resin powder supply.

[0050] Reference Figure 3 Specifically, the connecting part 9 includes a connecting sleeve 91, a connecting plate 92, two supporting plates 93, four connecting frames 94 and an elastic member 95. The connecting sleeve 91 is fixedly mounted on the weighing part 7, and the connecting plate 92 is fixedly mounted on the bottom wall of the connecting sleeve 91 and located on the bottom wall of the weighing part 7. The four connecting frames 94 are fixedly mounted on the bottom wall of the connecting plate 92 and are symmetrically located on both sides of the second vibrating part 6 in the width direction.

[0051] Two support plates 93 are fixedly mounted on opposite side walls in the width direction of the second vibrating part 6, the support plates 93 are mounted in the horizontal direction, and each two elastic members 95 are fixedly mounted on the bottom walls at both ends of the length direction of one support plate 93, and the four elastic members 95 are respectively located in four connecting frames 94, and the bottom ends of the elastic members 95 are fixedly connected to the inner wall of the support block. In the present application, the elastic member 95 can be selected as a spring.

[0052] When the second vibrating part 6 drives the feeding plate 4 to vibrate, the second vibrating part 6 drives the two supporting plates 93 to vibrate on the four elastic parts 95. The four elastic parts 95 filter the vibration of the second vibrating part 6, reducing the vibration transmitted to the weighing part 7, thereby making the weighing of the weighing part 7 more accurate.

[0053] Reference Figure 3 , Figure 5 and Figure 6 The first clamping plate 10 is fixedly mounted on one side of the bottom end of the second vibrating part 6 along its width direction, and the second clamping plate 13 is adjustable in the horizontal direction on the other side of the bottom end of the second vibrating part 6 along its width direction, and an adjusting member 14 is inserted into the second clamping plate 13, and the end of the adjusting member 14 is threadedly fixedly mounted in the second vibrating part 6. In the present application, the adjusting member 14 can be selected as a hand-tightened bolt.

[0054] A top cover 15 is fixedly mounted on the top wall of the feed plate 4 located below the second vibrating portion 6, and the width of the top cover 15 is greater than the width of the feed plate 4. The adjusting member 14 is rotated forward, and the adjusting member 14 drives the second clamping plate 13 to move toward the first clamping plate 10, so that the second clamping plate 13 and the first clamping plate 10 clamp and fix the top cover 15, thereby being able to fix the feed plate 4 to the bottom of the second vibrating portion 6. The adjusting member 14 is rotated backward, and the second clamping plate 13 can move away from the first clamping plate 10, so that the second clamping plate 13 and the first clamping plate 10 release the clamping and fixing of the top cover 15, thereby facilitating the removal of the feed plate 4 from the second vibrating portion 6.

[0055] Reference Figure 2 and Figure 4 A support rod 20 is fixedly installed on the bottom wall of the bracket 16 in the vertical direction, and a telescopic member 21 is rotatably installed on the bottom end of the support rod 20. The fixed end of the telescopic member 21 is rotatably connected to the support rod 20. In the present application, the telescopic member 21 can be selected as a cylinder. A moving block 43 is installed on the side of the bracket 16 close to the discharge port of the silo 1. A guide rod 52 is fixedly installed on the side wall of the moving block 43.

A material blocking cover 19 is fixedly mounted between the two guide blocks 23, the bottom end of the material blocking cover 19 is opened, and the sliding cover of the material blocking cover 19 is arranged at the discharge port of the silo 1.

[0057] When the silo 1 needs to be fed, the telescopic member 21 extends, and the telescopic end of the telescopic member 21 drives the first connecting arm 17 and the second connecting arm 18 to rotate. Under the action of the first connecting arm 17, the second connecting arm 18 pushes the moving block 43 to move away from the silo 1, and the moving block 43 drives the two guide blocks 23 to slide on the two guide columns 22, and the moving block 43 drives the material blocking cover 19 to move away from the silo 1, thereby opening the discharge port of the silo 1.

[0058] When the silo 1 does not need to be fed, the telescopic member 21 is shortened, and the telescopic end of the telescopic member 21 drives the first connecting arm 17 and the second connecting arm 18 to rotate. Under the action of the first connecting arm 17, the second connecting arm 18 pushes the moving block 43 to move toward the silo 1, and the moving block 43 drives the two guide blocks 23 to slide on the two guide columns 22, and the moving block 43 drives the material blocking cover 19 to move toward the silo 1, thereby closing the discharge port of the silo 1.

In this application, the translation component 51 can be selected as a linear module. The guide bucket 25, the hopper 3, the feeding plate 4, the second vibration part 6 and the weighing part 7 are installed in two groups at intervals along the translation direction of the translation component 51. The translation component 51 can drive the silo 1 to reciprocate, so that the two groups of feeding plates 4 can feed at the same time, thereby improving the feeding efficiency of the resin powder.

[0060] The implementation principle of an inverted resin powder supply device in Example 1 of the present application is as follows: the resin powder is poured into the silo 1 through the feed port, the first vibrating part 2 drives the hopper 3 to vibrate, so that the resin powder in the hopper 3 is transported out from the discharge port, and the resin powder transported out of the discharge port of the silo 1 falls into the hopper 3 through the guide bucket 25. The second vibrator drives the feed plate 4 and the hopper 3 to vibrate, and the resin powder in the hopper 3 enters the feed trough 5 of the feed plate 4, and the resin powder falls from the discharge port of the feed plate 4 through the feed trough 5 onto the tray 8. The second vibrating part 6 and the weighing part 7 are both located above the feed plate 4, so that the feed plate 4 can be installed at the bottom of the inner cavity of the chassis 50. When the discharge end of the feed plate 4 extends out of the chassis 50 for a short length, the height difference between the discharge end of the feed plate 4 and the tray 8 is also reduced, thereby improving the accuracy of the resin powder supply.

[0065] A connecting rod 32 is installed at the connection between the first connecting arm 17, the second connecting arm 18 and the telescopic end of the telescopic member 21. The connecting rod 32 is installed in the horizontal direction. Second connecting rods 31 are rotatably installed at both ends of the connecting rod 32. The top ends of the two second connecting rods 31 are rotatably connected to the side walls of the two first connecting rods 30.

[0066] When the resin powder is placed in the silo 1 for a long time, the resin powder will absorb moisture in the air in the silo 1, and then become damp. When the resin powder is poured into the silo 1, the feed door 26 is turned and closed, and the inside of the silo 1 is sucked using the suction pipe 27, so that the resin powder in the silo 1 is not easily dampened by absorbing moisture in the air.

[0067] When the telescopic member 21 is shortened, the material blocking cover 19 moves to close the discharge port of the second bin body 12, and the telescopic end of the telescopic member 21 drives the connecting rod 32 to move downward, and the connecting rod 32 drives the two first connecting rods 30 to slide downward in the limit block 29 along the vertical direction through the two second connecting rods 31, and the first connecting rod 30 drives the first gear 33 to rotate through the first rack 35, and the first gear 33 drives the second gear 34 to rotate through the rotating shaft, and the second gear 34 drives the sealing door 28 to move up through the second rack 36, so that the inner cavities of the first bin body 11 and the second bin body 12 are connected, so that the suction pipe 27 can suck out the air in the first bin body 11 and the second bin body 12.

[0068] When the silo 1 needs to be fed, the first vibrating part 2 first drives the silo 1 to vibrate, and the resin powder in the first silo body 11 is transported to the second silo body 12. The telescopic member 21 is further extended, and the blocking cover 19 moves to open the discharge port of the second silo body 12. The telescopic end of the telescopic member 21 drives the connecting rod 32 to move upward, and the connecting rod 32 drives the sealing door 28 to move downward through the second connecting rod 31, the first connecting rod 30, the first rack 35, the first gear 33, the rotating shaft, the second gear 34 and the second rack 36. The sealing door 28 moves into the second silo body 12 and separates the first silo body 11 from the second silo body 12. In this way, when the resin powder in the second silo body 12 is fed, the outside air is not easy to enter the first silo body 11, so that the resin powder in the first silo body 11 is not easy to be affected by moisture.

[0069] Reference Fig.10 and 11The first sealing strip 37 is fixedly installed in the middle of the bottom wall of the sealing door 28 along its length direction, and the bottom of the sealing door 28 is provided with accommodating cavities 46 on both sides of the width direction of the first sealing strip 37, and the sealing door 28 is provided with a material dividing plate 38 slidably installed in each accommodating cavity 46. The sealing door 28 is provided with a sliding groove 41 obliquely opened on both end walls of each accommodating cavity 46 in the length direction, the bottom end of the sliding groove 41 is inclined toward the inside of the sealing door 28, and the top end of the sliding groove 41 is inclined toward the outside of the sealing door 28. Slide blocks 42 are fixedly installed at the top of the two side walls in the length direction of the material dividing plate 38, and the two slide blocks 42 are slidably installed in the two sliding grooves 41. When the slide block 42 slides from the bottom end of the sliding groove 41 to the top end of the sliding groove 41, the material dividing plate 38 slides obliquely in the accommodating cavity 46 in the direction away from the sealing door 28.

[0070] A plurality of elastic reset members 39 are connected to the side walls of the two material dividing plates 38 that are close to each other. A plurality of avoidance grooves 53 are provided in the sealing door 28 at equal intervals along its length direction. The plurality of elastic reset members 39 are respectively located in the plurality of avoidance grooves 53. In the present application, the elastic reset members 39 can be selected as springs. The plurality of elastic reset members 39 pull the two material dividing plates 38 to move toward each other, and the material dividing plates 38 drive the slider 42 to move to the bottom end of the slide groove 41. At this time, the bottom end of the material dividing plate 38 extends to the bottom of the sealing door 28.

[0071] The two sides of the bottom of the two material dividing plates 38 that are away from each other are both formed with inclined surfaces 40, and the two side walls in the width direction of the sealing door 28 are both spaced apart along the length direction thereof and are provided with a plurality of discharge grooves 48 that are connected to the accommodating cavity 46. A retaining ring 49 is formed extending outward from the top of the sealing door 28, and a second sealing ring 45 is embedded and installed in the bottom wall of the retaining ring 49. Blocks 54 are integrally formed on the two opposite side walls in the width direction of the sealing door 28, and slots 55 are formed on the top wall of the inner cavity of the second bin body 12 and on both sides in the width direction of the sealing door 28, and a second sealing strip 47 is embedded and installed on the block 54.

[0072] When the sealing door 28 moves upward, the sealing door 28 drives the two clamping blocks 54 to move upward, and the clamping blocks 54 move into the clamping groove 55 and abut against the second sealing strip 47, so as to seal the sealing door 28 and the second bin body 12. When the sealing door 28 moves downward, the inclined surfaces 40 at the bottom of the two material dividing plates 38 make the bottoms of the two material dividing plates 38 sharp-angled, so as to facilitate the distribution of the resin powder to the two sides of the two material dividing plates 38, and part of the distributed resin powder enters the accommodating chamber 46, and then is discharged from the accommodating chamber 46 through the discharge slot 48.

[0073] When the bottom of the material dividing plate 38 contacts the bottom wall of the inner cavity of the second bin body 12, the material dividing plate 38 stops moving downward, and the sealing door 28 continues to move downward, and the slider 42 moves in the slide groove 41, so that the two material dividing plates 38 interact in the direction away from each other, and the two material dividing plates 38 separate the resin powder at the bottom of the inner cavity of the second bin body 12, and the two material dividing plates 38 pull the multiple elastic reset members 39 to deform and stretch. The sealing door 28 drives the first sealing strip 37 to move against the bottom wall of the inner cavity of the second bin body 12, thereby improving the effect of the sealing door 28 in separating the first bin body 11 and the second bin body 12. At the same time, the sealing door 28 drives the second sealing ring 45 to press against the top wall of the second bin body 12 through the retaining ring 49, so that the sealing door 28 and the second bin body 12 can be sealed.

[0074] When the sealing door 28 moves upward again, the sealing door 28 drives the two material dividing plates 38 to move upward, and the elastic reset member 39 pulls the two material dividing plates 38 to move toward each other.

[0075] The implementation principle of Example 2 of the present application is as follows: when the resin powder is poured into the silo 1, the feed door 26 is rotated to close, and the suction pipe 27 is used to suck air inside the silo 1, so that the resin powder in the silo 1 is not easily dampened by absorbing moisture in the air. When the silo 1 needs to be fed, the first vibrating part 2 first drives the silo 1 to vibrate, and the resin powder in the first bin body 11 is transported to the second bin body 12. The telescopic member 21 is extended again, and the material blocking cover 19 moves to open the discharge port of the second bin body 12. The telescopic end of the telescopic member 21 drives the connecting rod 32 to move upward, and the connecting rod 32 then drives the sealing door 28 to move downward through the second connecting rod 31, the first connecting rod 30, the first rack 35, the first gear 33, the rotating shaft, the second gear 34 and the second rack 36. The sealing door 28 moves into the second bin body 12 and separates the first bin body 11 from the second bin body 12. In this way, when the resin powder in the second bin body 12 is fed, it is difficult for outside air to enter the first bin body 11, so that the resin powder in the first bin body 11 is not easily affected by moisture.
