Description

Technical Field

[0001] The invention relates to the technical field of chip packaging, in particular to a USB chip packaging storage device. Background Art

[0002] A USB chip is a chip that communicates according to the USB bus protocol and converts USB communication content into other interfaces (such as SPI, I2C) or potential signals through an MCU (such as a 51 single-chip microcomputer) to control other devices. The USB chip production process is a complex and delicate process that involves multiple key steps to ensure the quality and performance of the final product.

[0003] The USB chip packaging process is an important part of the chip manufacturing process, which aims to wrap and protect the chip, metal leads, brackets and other components, and achieve the goal of appearance molding. In the USB chip plastic packaging process, the packaging device usually includes molds, plastic packaging material injection systems, heating and cooling systems and other parts. In the compression molding stage, these devices control parameters such as temperature, pressure and time to make the plastic packaging material softened by heat and fill the mold, and then solidify and form.

[0004] During the packaging process, the plastic packaging material will soften and flow after being heated to fill the space in the mold and cover the chip. However, due to the fluidity characteristics of the plastic packaging material and the complex structure of the mold, part of the plastic packaging material cannot be completely separated from the mold surface or fine structure, and thus remains in the mold after the plastic packaging box is taken out. These residual plastic packaging materials will produce a sticky effect with the plastic packaging box, which not only increases the difficulty for the staff to remove the plastic packaging box, but also requires the staff to clean the mold in time after each time the plastic packaging box is taken out, which increases the workload of the staff. For this reason, we propose a USB chip packaging storage device. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] See also Figures 1 to 10 The present invention provides a technical solution: a USB chip packaging storage device, comprising a packaging machine body 1; further comprising a plastic packaging box 2, which can be fitted with a mold in the packaging machine body 1; a feeding mechanism 3, which is connected to the packaging machine body 1, and transfers the plastic packaging box 2 containing the chip to the mold of the packaging machine body 1, and separates the plastic packaging box 2 from the packaging machine body 1 after the chip is plastic-sealed, and the feeding mechanism 3 automatically monitors the thrust change of the feeding mechanism 3 on the plastic packaging box 2 before and after the plastic packaging box 2 is separated from the packaging machine body 1; a cleaning mechanism 4, which is located outside the mold of the packaging machine body 1, and when the feeding mechanism 3 separates the plastic packaging box 2 from the packaging machine body 1, according to the thrust change monitored by the feeding mechanism 3, the cleaning mechanism 4 selects different cleaning forces when cleaning the mold of the packaging machine body 1.

[0034] When in use, the unloading robot of the production line transfers the unpackaged chip into the plastic packaging box 2, and the plastic packaging box 2 with the chip is transferred to the mold surface of the packaging machine body 1 through the unloading mechanism 3. The mold of the packaging machine body 1 is closed to cooperate to seal the plastic packaging box 2. The packaging machine body 1 heats the plastic packaging material so that the heated plastic packaging material flows into the plastic packaging box 2 to package the chip. After the packaging machine body 1 is cooled, the mold of the packaging machine body 1 is opened, and the unloading mechanism 3 automatically separates the plastic packaging box 2 from the mold surface of the packaging machine body 1. The unloading mechanism 3 detects the thrust change before and after the separation of the plastic packaging box 2 from the mold surface, thereby judging the residual amount of plastic packaging material sticking to the plastic packaging box 2 in the mold.

[0035] If there is a lot of residual plastic packaging material in the mold, the sticky effect between the residual plastic packaging material and the plastic packaging box 2 will cause the thrust of the unloading mechanism 3 to increase. When the plastic packaging box 2 is completely separated from the mold of the packaging machine body 1, the thrust of the unloading mechanism 3 on the plastic packaging box 2 is equal to the sum of the weight of the plastic packaging box 2 and the packaged chip. Therefore, the amount of residual plastic packaging material in the mold of the packaging machine body 1 can be judged by the change in the thrust on the plastic packaging box 2.

[0036] By detecting the thrust change of the unloading mechanism 3, the cleaning mechanism 4 selects different cleaning forces when cleaning the mold of the packaging machine body 1, so as to clean the residual plastic sealing material on the surface of the mold, and avoid excessive cleaning force of the plastic sealing material causing the residual plastic sealing material to be dispersed to other locations in the production environment.

[0037] The unloading mechanism 3 includes a support plate 30, and a plurality of grooves 31 are provided on the surface of the support plate 30. The grooves 31 are used to place the handles of the plastic packaging box 2. A limit piece 32 for fixing the handles of the plastic packaging box 2 is provided on the surface of the support plate 30. A movable plate 33 is provided at the bottom of the support plate 30. An upper push piece 34 for pushing the support plate 30 to move is provided between the movable plate 33 and the support plate 30. When the upper push piece 34 lifts the support plate 30, the thrust change is detected. A pneumatic telescopic rod 35 is fixedly connected to the inner side of the movable plate 33. The pneumatic telescopic rod 35 is installed on the surface of the packaging machine body 1. A telescopic column 36 is fixedly connected to the side of the movable plate 33 close to the pneumatic telescopic rod 35. The end of the telescopic column 36 away from the movable plate 33 is fixedly connected to the packaging machine body 1.

[0038] After the chip is placed in the plastic packaging box 2, the handle of the plastic packaging box 2 is fitted into the groove 31 on the surface of the support plate 30, and the handle of the plastic packaging box 2 is fixed with the limiter 32. After the plastic packaging box 2 is fixed, the pneumatic telescopic rod 35 contracts to drive the moving plate 33 to move, and the moving plate 33 drives the telescopic column 36 to contract, and the movement of the moving plate 33 drives the upper ejector 34 to move, and the upper ejector 34 drives the support plate 30 to move, so that the support plate 30 moves the plastic packaging box 2 to the top of the mold of the packaging machine body 1, and the upper ejector 34 contracts to drive the plastic packaging box 2 downward. The packaging machine body 1 moves so as to stick to the surface of the mold, and the mold of the packaging machine body 1 is closed to cooperate with the sealing of the plastic packaging box 2. The packaging machine body 1 heats the plastic packaging material so that the heated plastic packaging material flows into the plastic packaging box 2 to package the chip. After the packaging machine body 1 is cooled, the mold of the packaging machine body 1 is opened, and the support plate 30 is lifted up by the upper ejector 34. The support plate 30 drives the plastic packaging box 2 to separate from the mold surface of the packaging machine body 1. When the upper ejector 34 lifts the support plate 30, the thrust change is detected, and the cleaning force of the cleaning mechanism 4 is adjusted according to the thrust change.

[0039] The limiting member 32 includes a limiting cover 37, and a rubber plate 38 is fixedly connected to one side of the limiting cover 37 close to the support plate 30. The rubber plate 38 is arc-shaped at one end close to the support plate 30. A rotating rod 39 is fixedly connected to one end of the limiting cover 37. The rotating rod 39 is rotatably connected to the inner wall of the support plate 30. The inner wall of the rotating rod 39 is slidably connected to a limiting rod 310. Both sides of the limiting rod 310 pass through the inner wall of the rotating rod 39. The inner wall of the support plate 30 is provided with a limiting groove 311 that is clamped with the limiting rod 310. The limiting groove 311 is divided into a clamping part 312 and a rotating part 313. One end of the limiting rod 310 abuts against an extrusion plate 314. A return spring 315 is fixedly connected to the outer side of the extrusion plate 314. The return spring 315 is fixedly connected to the inner wall of the rotating rod 39. The other end of the limiting rod 310 passes through the rotating rod 39 and is connected to the outside.

[0040] When releasing the limit on the handle of the plastic packaging box 2, the staff pushes the limit rod 310, and the limit rod 310 slides along the inner wall of the rotating rod 39. The limit rod 310 pushes the extrusion plate 314 so that the extrusion plate 314 squeezes the return spring 315, and the limit rod 310 slides on the inner wall of the supporting plate 30 when the inner wall of the rotating rod 39 slides, and the clamping part 312 of the limit groove 311 slides to the rotating part 313. At this time, the limit on the rotating rod 39 is released, and the staff rotates the limit cover 37 to separate the rubber plate 38 from the supporting plate 30, thereby releasing the clamping fixation of the handle of the plastic packaging box 2; similarly, the staff can rotate the limit cover 37 to make the limit cover 37 close to the supporting plate 30, and clamp the handle of the plastic packaging box 2 by cooperating with the rubber plate 38 and the groove 31 on the surface of the support plate 30.

[0041] The upper push piece 34 includes a push rod 316 fixedly connected to the bottom of the support plate 30, a fixed cylinder 317 fixedly connected to the top of the movable plate 33, an end of the push rod 316 close to the fixed cylinder 317 is fixedly connected to a piston plate 318, the piston plate 318 is slidably connected to the inner wall of the fixed cylinder 317, an air delivery piece 319 is provided on the outer side of the fixed cylinder 317, and a pressure sensor 320 is installed on the inner wall of the fixed cylinder 317.

[0042] When the upper push piece 34 pushes the support plate 30 upward, gas is injected into the inner wall of the fixed cylinder 317 through the gas delivery piece 319, so that the air pressure between the piston plate 318 and the bottom of the fixed cylinder 317 increases, and the pressure change at the bottom of the fixed cylinder 317 is detected by the pressure sensor 320, and the gas at the bottom of the fixed cylinder 317 generates an upward thrust on the piston plate 318. When the thrust of the air pressure on the piston plate 318 is sufficient to move the support plate 30 upward, the upward thrust of the air pressure between the piston plate 318 and the bottom of the fixed cylinder 317 on the piston plate 318 is equal to the sum of the weight of the plastic packaging box 2 and the packaged chip. The pressure when the support plate 30 is pushed is detected by the pressure sensor 320 and compared with the pressure when the support plate 30 rises steadily. The greater the pressure change, the more residual plastic packaging material is in the mold of the packaging machine main body 1, and the greater the cleaning force of the cleaning mechanism 4 is controlled.

[0043] The gas delivery component 319 includes an air inlet pipe 321 connected to the bottom of the fixed cylinder 317, the air inlet pipe 321 is connected to a three-way valve 322 at one end away from the fixed cylinder 317, the three-way valve 322 is installed on the inner wall of the packaging machine body 1, the inlet of the three-way valve 322 is connected to an air delivery pipe 323, the air delivery pipe 323 is connected to an air pump 324 at one end away from the three-way valve 322, the air pump 324 is connected to the pressure sensor 320, and the air pump 324 is installed on the inner wall of the packaging machine body 1.

[0044] The operation of the gas delivery member 319 is divided into two stages. The first stage is to push the support plate 30 upwards. At this time, the three-way valve 322 controls the gas delivery pipe 323 to be connected with the air inlet pipe 321. The output power of the air pump 324 is fixed. When the air pump 324 is working, it delivers gas to the bottom of the fixed cylinder 317 through the gas delivery pipe 323, the three-way valve 322 and the air inlet pipe 321, so that the air pressure between the piston plate 318 and the bottom of the fixed cylinder 317 increases, so as to cooperate with the piston plate 318 to slide on the inner wall of the fixed cylinder 317.

[0045] The second stage is the cleaning stage. When the air pressure at the bottom of the fixed cylinder 317 increases and the push rod 316 separates the plastic packaging box 2 from the mold of the packaging machine body 1, the pneumatic telescopic rod 35 extends to drive the movable plate 33 to move, and the movable plate 33 drives the fixed cylinder 317 to move, so that the plastic packaging box 2 leaves from between the upper and lower molds of the packaging machine body 1. The three-way valve 322 allows the gas pipe 323 to transport the gas to the cleaning mechanism 4, and the output power of the air pump 324 is related to the pressure change detected by the pressure sensor 320. The greater the pressure change detected by the pressure sensor 320, the greater the resistance generated by the residual plastic packaging material when the plastic packaging box 2 is separated from the packaging machine body 1, that is, the more plastic packaging material remains on the surface of the mold of the packaging machine body 1, and the greater the output power of the air pump 324, so that the cleaning mechanism 4 will produce a greater cleaning force.

[0046] The cleaning mechanism 4 includes fixed blocks 40 respectively located on both sides of the inner wall of the packaging machine body 1, and a Y-shaped tube 41 is provided on the inner wall of the packaging machine body 1. One end of the Y-shaped tube 41 is connected to the three-way valve 322, and the remaining two ends of the Y-shaped tube 41 are respectively connected to the two fixed blocks 40. A connecting groove 42 connected to the Y-shaped tube 41 is opened on the inner wall of the fixed block 40, and an air jet 43 is fixedly connected to the outer side of the fixed block 40. A plurality of corrugated parts are provided on the surface of the air jet 43. There are two corrugated parts of the air jet 43, one is located between the second steering rod 48 and the connecting seat 47, and the other is located between the first steering rod 45 and the fixed block 40. The air jet 43 is connected to the connecting groove 42, and a steering member 44 is provided on the outer side of the air jet 43. The steering member 44 controls the air jet 43 to spray toward the upper and lower mold surfaces of the packaging machine body 1.

[0047] When the cleaning mechanism 4 is working, the air pump 324 outputs gas to the air pipe 323. At this time, the three-way valve 322 connects the air pipe 323 with the Y-tube 41. The gas in the air pipe 323 enters the connecting groove 42 of the fixed block 40 through the Y-tube 41. The gas enters the jet pipe 43 through the connecting groove 42 and is ejected from the outlet of the jet pipe 43. The steering member 44 controls the jet pipe 43 to eject gas toward the upper and lower mold surfaces of the packaging machine body 1. The greater the output power of the air pump 324, the greater the cleaning force of the gas ejected from the jet pipe 43, so as to cooperate with the cleaning of the mold surface residues on the upper and lower sides of the packaging machine body 1.

[0048] The steering member 44 includes a steering rod 1 45 fixedly connected to the outer side of the jet pipe 43, the steering rod 1 45 is rotatably connected to the inner wall of the fixed block 40, a driving motor 1 46 is mounted on the surface of the fixed block 40, the output end of the driving motor 1 46 is fixedly connected to the steering rod 1 45, a connecting seat 47 is fixedly connected to the outer side of the steering rod 1 45, a steering rod 2 48 is rotatably connected to the inner wall of the connecting seat 47, the jet pipe 43 passes through the connecting seat 47 and the steering rod 2 48, a driving motor 2 49 is mounted on the surface of the connecting seat 47, the output end of the driving motor 2 49 is fixedly connected to the steering rod 2 48, and the driving motor 1 46 and the driving motor 2 49 work alternately.

[0049] When the steering member 44 is working, the driving motor 1 46 drives the steering rod 1 45 to rotate back and forth, and the steering rod 1 45 makes the connecting seat 47 swing up and down in the vertical direction, so that the air outlet position of the air injection pipe 43 swings up and down in the vertical direction to cooperate with the cleaning of the upper and lower mold surfaces of the packaging machine body 1; and the driving motor 2 49 is installed on the surface of the connecting seat 47. When the driving motor 2 49 is working, it will drive the steering rod 2 48 to swing back and forth, and the steering rod 2 48 drives the nozzle of the air injection pipe 43 to swing left and right to cooperate with the cleaning of the left and right sides of the mold of the packaging machine body 1, and the driving motor 1 46 drives the steering rod 1 45 to rotate fixedly. It will stop working after a certain angle. At this time, the driving motor 2 49 drives the steering rod 2 48 to swing left and right for multiple cycles to cooperate with the cleaning of the left and right sides of the mold of the packaging machine body 1. After the driving motor 2 49 completes its work, the driving motor 1 46 drives the steering rod 1 45 to rotate a fixed angle, and then repeats the above actions, thereby automatically cleaning the mold surface of the packaging machine body 1, and according to the change in force when the plastic packaging box 2 is removed, the flow rate of the gas sprayed out of the jet pipe 43 is controlled to cooperate with the residual plastic packaging material on the mold surface of the packaging machine body 1. When there is a lot of plastic packaging material, the gas flow rate can also be adaptively increased to more thoroughly clean the plastic packaging material residues.

[0050] Embodiment 2

[0051] In the second embodiment, other structures remain unchanged. What is different from the first embodiment is that the inner wall of the connecting seat 47 is provided with an adjusting member 5 for adjusting the flow cross-section of the jet pipe 43 when the steering rod 48 rotates. The adjusting member 5 includes a transmission gear 50 fixedly connected to the outer side of the steering rod 48. Two transmission tooth plates 51 are meshed on the outer side of the transmission gear 50. The two transmission tooth plates 51 are respectively located on both sides of the transmission gear 50. The transmission tooth plates 51 are slidably connected to the inner wall of the connecting seat 47. An oblique end 52 is provided at one end of the transmission tooth plate 51. An adjusting plate 53 is slidably connected to the outer side of the oblique end 52. The adjusting plate 53 is slidably connected to the inner wall of the connecting seat 47. The adjusting plate 53 is located on the outer side of the jet pipe 43. The adjusting plate 53 is obliquely transitioned close to the jet pipe 43. A compression spring 54 is fixedly connected to the bottom of the adjusting plate 53. One end of the compression spring 54 is fixedly connected to the inner wall of the connecting seat 47.

[0052] When the driving motor 2 49 drives the steering rod 2 48 to rotate back and forth, the steering rod 2 48 drives the adjusting part 5 to work, so that when the steering rod 2 48 drives the nozzle of the jet tube 43 to approach the edge of the mold of the packaging machine body 1, the gas flow cross-section of the jet tube 43 is gradually reduced, so that when the nozzle of the jet tube 43 gradually approaches the edge of the mold, the flow rate of the airflow ejected by the jet tube 43 gradually increases, so as to avoid incomplete cleaning of residual plastic packaging material at the edge due to the distance between the edge of the mold and the jet tube 43.

[0053] The specific working principle of the adjusting member 5 is as follows: when the steering rod 48 drives the nozzle of the jet pipe 43 to rotate toward the edge position of one end of the mold, the steering rod 48 rotates to drive the transmission gear 50 to rotate, and the transmission gear 50 drives the transmission tooth plate 51 to slide on the inner wall of the connecting seat 47, so that one of the two transmission tooth plates 51 is close to the adjusting plate 53, and the other transmission tooth plate 51 is away from the adjusting plate 53, and the oblique end 52 of the transmission tooth plate 51 close to the adjusting plate 53 squeezes the oblique edge of the adjusting plate 53, and the squeezed adjusting plate 53 slides on the inner wall of the connecting seat 47 and squeezes the compression spring 54, and when the adjusting plate 53 slides downward, the side of the oblique transition of the adjusting plate 53 will gradually squeeze the jet pipe 43, thereby reducing the gas flow cross-section of the jet pipe 43, so that the gas flow rate of the jet pipe 43 is increased.

[0054] When the steering rod 48 drives the nozzle of the jet pipe 43 to rotate toward the edge of the other end of the mold, the steering rod 48 rotates to drive the transmission gear 50 to rotate in the opposite direction, and the transmission gear 50 drives the transmission tooth plate 51 to slide on the inner wall of the connecting seat 47, so that one of the two transmission tooth plates 51 is away from the adjustment plate 53, and the other transmission tooth plate 51 is close to the adjustment plate 53, and the oblique end 52 of the transmission tooth plate 51 close to the adjustment plate 53 squeezes the oblique edge of the adjustment plate 53, and the squeezed adjustment plate 53 slides on the inner wall of the connecting seat 47 and squeezes the compression spring 54, while the adjustment plate 53 that does not squeeze the compression spring 54 will move upward under the elastic force of the compression spring 54, so that the other side of the jet pipe 43 is gradually squeezed, thereby continuing to change the flow rate of the gas ejected from the jet pipe 43.
