Detailed implementation manners

[0019] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following implementation manners are merely examples, and a semiconductor chip packaging box related to the present invention is not limited to the structures described in the following implementation manners. All other implementation manners obtained without creative efforts by those of ordinary skill in the art belong to the scope protected by the present invention.

[0020] Referring to Figures 1 to 3 , the present invention provides a semiconductor chip packaging box, including a box body 1, an airbag 2 fixedly connected inside the box body 1 for fixing chips, a sliding assembly 3 fixedly connected to the inner wall of the box body 1, a carrier plate 4 for loading chips, a gas storage tank 5 for storing gas, a telescopic rod assembly 6 movably connected inside the side wall shells on both sides of the box body 1, and a transmission assembly 7 movably connected to the telescopic rod assembly 6.

[0021] After the chips are loaded onto the carrier plate 4, they are fixed by the airbag 2. The sliding assembly 3 is used for the carrier plate 4 to slide in and out: when sliding out, the gas in the airbag 2 is transferred to the gas storage tank 5, the volume of the airbag 2 shrinks, and it separates from the chips at the top of the carrier plate 4; when sliding in, the gas in the gas storage tank 5 is filled into the airbag 2, the volume of the airbag 2 expands, contacts the chips at the top of the carrier plate 4, and presses them tightly.

[0022] In addition, the telescopic rod assembly 6 and the transmission assembly 7 cooperate to convert the force for opening the box body 1 into the force for triggering the carrier plate 4 to pop out.

[0023] Referring to Figure 3 and Figure 4, one side of the carrier plate 4 is in contact connection with a first clamping plate 41, the side surface of the first clamping plate 41 is movably connected with the inner wall of the box body 1 through a first spring 411, the other side of the carrier plate 4 is in contact connection with a second clamping plate 42, and the side surface of the second clamping plate 42 is movably connected with the side surface of the gas storage tank 5 through a spring. One side of the carrier plate 4 close to the inner cavity of the box body 1 is in contact connection with a second spring 43 and a third spring 44. A sleeve 431 is sleeved outside the second spring 43, and one end of the sleeve 431 is fixedly connected with the inner wall of the box body 1. One end of the second spring 43 is movably connected with the transmission assembly 7. The third spring 44 is sleeved on one end of the gas storage tank 5. A fixing ring is fixedly connected to the side surface of the gas storage tank 5, and the gas storage tank 5 is fixedly connected with the inner wall of the box body 1 through the fixing ring.

[0024] The first clamping plate 41, the second clamping plate 42, the second spring 43 and the third spring 44 on three sides of the carrier plate 4 provide a buffering force for the carrier plate 4. Among them, the first clamping plate 41 and the second clamping plate 42 are symmetrically arranged, and the ends of both of them close to the outside of the box body 1 are bent. The edge of the side of the carrier plate 4 close to the inside of the box body 1 is rounded. When the carrier plate 4 slides out of the inside of the box body 1, the first clamping plate 41 and the second clamping plate 42 push towards each other under the action of the spring restoring force, and the distance between them is less than the long side of the carrier plate 4. When the carrier plate 4 returns to the inside of the box body 1, the rounded edge will slide into the space between the first clamping plate 41 and the second clamping plate 42 along the arc at the end of the first clamping plate 41 and the second clamping plate 42, and the spring is compressed again.

[0025] Refer to Figures 3 to 6 , support plates 21 are fixedly connected to both sides of the airbag 2. The top ends of the support plates 21 are fixedly connected to the inner top end of the box body 1, and the bottom ends of the support plates 21 are fixedly connected to the inner bottom end of the box body 1. A sliding assembly 3 is arranged below the airbag 2. The sliding assembly 3 includes a backing plate 31 fixedly connected to the inner wall of the box body 1, a slide rail 32 fixedly connected to the top end of the backing plate 31, a slide bar 33 movably connected to the inner wall of the slide rail 32, a stop block 34 arranged at one end of the slide rail 32 close to the outside of the box body 1, a rail bar 35 movably connected to the bottom end of the slide bar 33 and the inner wall of the slide rail 32, and a card slot 36 opened at the top end of the rail bar 35. The top end of the slide bar 33 is fixedly connected to the bottom end of the carrier plate 4.

[0026] When the box body 1 is in the closed state, the carrier plate 4 is located directly below the airbag 2. At this time, the slide bar 33 is located in the middle of the slide rail 32, and the stop block 34 is located at one end of the slide bar 33. A rod is inserted into the stop block 34, and the rod is fixedly connected to the backing plate 31. When the box body 1 is opened, the rail bar 35 slides out. When the card slot 36 slides below the stop block 34, the stop block 34 drops along the rod and engages with the card slot 36. Then the slide bar 33 loses the block and slides out along the rail bar 35. The top surface of the stop block 34 is slightly higher than the top surface of the rail bar 35. A long slot adapted to the top end of the stop block 34 is opened at the bottom end of the slide bar 33. After the end of the long slot is caught by the stop block 34, the slide bar 33 stops sliding, that is, the carrier plate 4 stops sliding out. At this time, the carrier plate 4 completely slides out of the box body 1 (see Figure 2 ).

[0027] Refer to Figure 7 and Figure 8 As shown in FIGS. and, the gas storage tank 5 includes a tank body 51, a double-headed plug 52 movably connected to one end of the tank body 51, a piston rod two 53 movably connected to the other end of the tank body 51, a connecting pipe 54 fixedly connected to the top end of the tank body 51, and a block 55 fixedly connected to one end of the piston rod two 53. One end of the connecting pipe 54 is fixedly connected to the side surface of the airbag 2 and is internally connected.

[0028] Among them, one end of the double-headed plug 52 is movably connected with a hydraulic pipe 521. Piston heads are fixedly connected to both ends of the double-headed plug 52, and the piston heads are respectively adapted to the interiors of the tank body 51 and the hydraulic pipe 521. The hydraulic pipe 521 is fixedly connected to the inner wall of the box body 1 through a fixed sleeve fixedly connected to the side surface. One end of the hydraulic pipe 521 is movably connected with a piston rod one 522. The piston rod one 522 is inserted into the interior of a spring three 44. One end of the spring three 44 is fixedly connected with a bracket, and one end of the bracket is fixedly connected to the inner wall of the box body 1.

[0029] One end of the piston rod one 522 is in contact connection with the side surface of the carrier plate 4. The vibration received by the carrier plate 4 is transmitted to the piston rod one 522, and is converted into a thrust force of the piston rod one 522 on the hydraulic pipe 521. One end of the hydraulic pipe 521 is pressed, and the internal liquid pushes the double-headed plug 52 at the other end to advance towards the tank body 51, squeezing the gas inside the tank body 51. Then, the gas inside the tank body 51 enters the airbag 2 through the connecting pipe 54, causing the airbag 2 to further expand, fit more closely with the chip, and further strengthen the fixing effect of the airbag 2 on the chip.

[0030] Among them, a sliding sleeve 511 is fixedly connected to one end of the tank body 51 close to the outside of the box body 1. The interior of the sliding sleeve 511 is movably connected to the side surface of the piston rod two 53, and the inner diameter of the sliding sleeve 511 is adapted to the rod diameter of the piston rod two 53. A piston head is fixedly connected to one end of the piston rod two 53, and the piston head is adapted to the interior of the tank body 51. A limiting block 531 is fixedly connected to the side surface of the piston rod two 53.

[0031] When the box body 1 is in the closed state, the piston head at the end of the piston rod two 53 is located at about the middle inside the tank body 51, and the limiting block 531 is in contact connection with the sliding sleeve 511. After the box body 1 is opened, the piston rod two 53 is pulled out until the piston head located inside the tank body 51 moves to the end of the tank body 51 and stops. At this time, the gas is pumped out from the airbag 2 into the tank body 51, and the volume of the airbag 2 collapses and separates from the chip.

[0032] Refer to Figure 3 As shown in FIG., the telescopic rod assembly 6 includes a sleeve rod 61 movably connected to the inner parts of the two side wall shells of the box body 1 and a telescopic rod one 62 movably connected to the inside of the sleeve rod 61. One end of the sleeve rod 61 on the side opposite to the gas storage tank 5 is provided with a thread.

[0033] When the length that the first telescopic rod 62 slides out of the sleeve rod 61 is four-fifths of its own length, it locks with the sleeve rod 61 and drives the sleeve rod 61 to move together.

[0034] Refer to Figure 9 , a first gear is movably connected to the threaded end of the sleeve rod 61, a rack 71 is meshed with the edge of the first gear, a driven gear 72 is meshed with the bottom end of the rack 71, wherein the tooth number ratio of the first gear to the driven gear 72 is 1∶3, a push rod 73 is threadedly connected to the axis center of the driven gear 72, one end of the push rod 73 is fixedly connected with a circular plate, and the outer diameter of the circular plate is adapted to the inner diameter of the sleeve 431.

[0035] The first gear, the rack 71 and the driven gear 72 are movably connected inside the fixing plate, corresponding grooves are formed on one side of the fixing plate, and the fixing plate is fixedly connected to the side surface of the box body 1.

[0036] Refer to Figure 1 and Figure 2 , one end of the first telescopic rod 62 is fixedly connected with a sliding door 11, one end of the sliding door 11 is fixedly connected with the rail 35, the length and width of the sliding door 11 are adapted to the internal space size of the box body 1, and by pulling the handle on the side of the sliding door 11, the sliding door 11 can be pulled out to drive the carrier plate 4 to slide out; by pushing the sliding door 11 to close, the carrier plate 4 can be driven into the box body 1.

[0037] Refer to Figure 10 , a clamping seat 12 is fixedly connected to the side surface of the sliding door 11, and the clamping seats 12 correspond to the clamping blocks 55 one by one.

[0038] When the box body 1 is closed, the clamping seat 12 and the clamping block 55 are in a clamped state. At this time, by pulling out the sliding door 11, the piston rod two 53 can be pulled out through the clamped clamping seat 12 and clamping block 55 until the piston head of the piston rod two 53 is located at the end of the tank body 51 and cannot be pulled, and the clamping seat 12 and the clamping block 55 are separated. In this process, the gas is pumped from the air bag 2 into the tank body 51. At this time, the sliding door 11 continues to be pulled out until the clamping groove 36 at the top of the rail 35 is clamped with the stop block 34.

[0039] When the sliding door 11 is closed, the clamping seat 12 first contacts the clamping block 55, and then pushes the piston rod two 53 to move towards the tank body 51 until the limiting block 531 abuts against the sliding sleeve 511. At this time, by continuing to push the sliding door 11, the clamping seat 12 and the clamping block 55 can be clamped.

[0040] The working principle of the present invention: The working principle of the carrier plate popping up is as follows: the sliding door 11 is pulled open laterally by the handle, and the telescopic rod 1 62 and the rail 35 are synchronously brought out. The part of the telescopic rod 1 62 located inside the sleeve rod 61 is stuck when one-fifth of its own length is left, driving the sleeve rod 61 to move synchronously in the direction of the sliding door 11. At this time, the lateral displacement of the sleeve rod 61 drives the transmission assembly 7 to operate, so that the push rod 73 moves in the direction of the spring 2 43. The spring 2 43 is compressed and generates a restoring force. When the end of the rail 35 moves away from the sliding door 11 to the end of the slide rail 32 close to the sliding door 11, the stopper 34 falls into the card slot 36 at its top, and the two are engaged, and the sliding door 11 reaches the predetermined distance of horizontal opening. At the same time, the carrier plate 4 loses the obstruction of the stopper 34. Under the action of the restoring force of the spring 2 43, the slide bar 33 slides out along the slide rail 32 and the rail 35 until the stopper 34 is stuck in the long groove at the bottom end of the slide bar 33, and the carrier plate 4 slides out completely (such as Figure 6 ).

[0041] Working principle of airbag fixing chip: after the chip is loaded onto the carrier 4, the sliding door 11 is pushed to close. At this time, the carrier 4 moves toward the bottom of the airbag 2 along the slide rail 32 and the track 35 under the push of the sliding door 11. When the sliding door 11 is still one-third of the length of the telescopic rod 62 away from the box body 1, the sliding door 11 contacts the end of the piston rod 53 and pushes the piston rod 53 to move toward the inside of the gas tank 5. At this time, the gas inside the gas tank 5 is squeezed, and the gas enters the airbag 2 through the connecting pipe 54. The airbag 2 gradually expands. When the carrier 4 moves completely to the bottom of the airbag 2, the holder 12 resists the end of the piston rod 53 and continues forward until it engages with the block 55. At this time, the gas inside the gas tank 5 is squeezed into the airbag 2 and the airbag 2 is fully expanded, thereby fixing the chip at the top of the carrier 4.

[0042] The working principle of the carrier plate spring shock absorption: the clamp plate 1 41 and the clamp plate 2 42 clamp the carrier plate 4 from both sides to absorb the lateral vibration energy of the carrier plate 4. In the longitudinal direction, a stop block 34 is provided on the side of the carrier plate 4 close to the sliding door 11, and the spring 2 43 and the spring 3 44 on the other side absorb its longitudinal vibration energy. The two ends of the side of the carrier plate 4 close to the inside of the box body 1 are rounded, and the ends of the clamp plate 1 41 and the clamp plate 2 42 close to the sliding door 11 have a certain curvature, and the carrier plate 4 moves in and out between the clamp plate 1 41 and the clamp plate 2 42 along the curvature.

[0043] The working principle of the linkage between the carrier plate spring and the air tank: when the box body 1 is closed, the vibration of the carrier plate 4 is converted into a thrust on the liquid inside the hydraulic tube 521 through the piston rod 522, and the thrust is transmitted to the double-headed plug 52 located at the other end of the hydraulic tube 521, and converted into the pressure of the double-headed plug 52 on the gas inside the air tank 5. The gas inside the air tank 5 is squeezed into the airbag 2 through the connecting tube 54, further enhancing the expansion of the airbag 2.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
