Description

Technical Field

[0001] This application relates to the field of chip storage technology, and more specifically, to a moisture-proof and shockproof chip storage box. Background Technology

[0002] A chip, also known as an integrated circuit, is a miniature electronic device or component that integrates a large number of electronic components such as transistors, resistors, and capacitors, as well as the circuits connecting them, onto a small piece of semiconductor material (usually silicon) to achieve a specific electronic function. The chip die needs to be packaged in a plastic or ceramic shell and connected to an external circuit through pins.

[0003] Chip structures are intricate, and the surrounding pins are prone to deformation. Furthermore, the pins are often made of highly conductive metals, making them susceptible to moisture and dust. This variability means they are easily deformed and damaged by external impacts, affecting performance. Therefore, they need to be stored in boxes to prevent damage during transport. While traditional chip storage boxes contain desiccants for moisture protection, these desiccants become ineffective once saturated, making it difficult for staff to determine replacement times and causing inconvenience. Additionally, the chip fixing structure in traditional storage boxes requires manual fixing and loosening, which is cumbersome and warrants further improvement.

[0004] To address the aforementioned issues, this application provides a moisture-proof and shock-proof chip storage box. Utility Model Content

[0005] The moisture-proof and shock-proof chip storage box provided in this application adopts the following technical solution: A moisture-proof and shockproof chip storage box includes a box body and a box cover. A storage slot is fixedly installed inside the box body. The storage slot is a groove-shaped structure used to hold a supporting sponge layer. The supporting sponge layer has good air permeability and is made of high-density polyurethane sponge. Multiple placement slots are arranged on the top surface of the supporting sponge layer, and their size is larger than the chip size. A color-changing desiccant, made of common materials, is filled inside the box body below the storage slot. A base plate is fixedly installed on the bottom surface of the box body, and an observation window made of transparent acrylic sheet is embedded in the surface of the base plate.

[0006] Through the above technical solution, using a color-changing desiccant and an observation window, when the box lid is closed, the color-changing desiccant can absorb moisture inside the box, preventing moisture from affecting chip storage. At the same time, the color-changing desiccant changes color after saturation, and users can easily observe the color change through the observation window, thereby determining the replacement time and improving the convenience of use.

[0007] Furthermore, a lid is hinged to the top surface of the box body, and a lid is hinged to the back surface of the box body (not shown in the figure). A pressure post is fixedly installed on the top surface inside the lid to press down the corresponding placement slot, and a rubber post is fixedly glued to the bottom surface of the pressure post.

[0008] With the above technical solution, the distance between the bottom surface of the rubber pillar and the bottom surface of the placement slot is less than the chip thickness, which facilitates stable chip clamping and prevents chip shaking. After the chip is placed in the placement slot and the cover is closed, the rubber pillar presses against the chip to fix it and prevent the chip from shaking randomly. The flexible structure of the supporting sponge layer and the rubber pillar can buffer and absorb shock, preventing chip damage caused by vibration during movement. At the same time, after the cover is opened, the rubber pillar automatically leaves the chip, completing the fixation and release. The fixation and release of the chip are very convenient, further improving the ease of use.

[0009] Furthermore, the front of the box is fixedly connected to the lid by a spring lock.

[0010] The above technical solution involves two sets of spring locks, which is a common locking structure and will not be elaborated further here.

[0011] Furthermore, a base foot is fixedly installed at the corner of the bottom surface of the box.

[0012] The above technical solution involves four sets of feet made of rubber, which provide a certain degree of shock absorption and further improve the shock resistance. At the same time, the surface of the feet is roughened to increase friction during placement, thereby improving the stability of the placement.

[0013] Furthermore, the base plate is fixedly connected to the bottom surface of the box by fixing screws. There are four sets of fixing screws, and screw holes are opened on the surface of the base plate for the fixing screws to pass through.

[0014] With the above technical solution, a threaded blind hole is opened on the bottom surface of the base plate to engage with the threaded screw. The fixing screw passes through the screw hole and enters the threaded blind hole, and the threaded blind hole engages with the threaded blind hole to fix the base plate.

[0015] Furthermore, the bottom surface of the box body has a bottom opening, the size of which is smaller than the size of the bottom plate.

[0016] The above technical solution facilitates the removal and re-addition of the color-changing moisture-proof agent after opening the bottom plate.

[0017] Furthermore, the bottom surface of the holding tank is provided with ventilation holes, and multiple sets of ventilation holes are densely and evenly distributed at equal intervals.

[0018] Through the above technical solution, the vents facilitate airflow, which in turn facilitates the absorption and removal of moisture from the box by the color-changing desiccant.

[0019] In summary, this application includes the following beneficial technical effects: With its color-changing desiccant and observation window, the desiccant absorbs moisture from inside the box when the lid is closed, preventing moisture from affecting chip storage. The desiccant changes color upon saturation, and users can easily observe this color change through the observation window to determine replacement time, improving ease of use. Additionally, when the chip is placed in the slot and the lid is closed, rubber posts hold the chip in place, preventing it from moving around. The flexible structure of the supporting sponge layer and rubber posts provides cushioning and shock absorption, preventing damage to the chip during movement. Furthermore, opening the lid automatically releases the rubber posts from the chip, completing the secure release. Both securing and releasing the chip are very convenient, further enhancing usability. Attached Figure Description

[0025] Example:

[0026] This application discloses a moisture-proof and shock-proof chip storage box. Please refer to [link / reference]. Figure 1 and Figure 4 The system includes a box body 1 and a lid 2. Box body 1 is made of high-strength ABS engineering plastic, manufactured through injection molding, with a wall thickness of 3mm. The surface is treated with anti-static spraying, resulting in a surface resistivity of ≤10^9Ω, effectively preventing damage to the chip from static electricity. A holding slot 3 is fixedly installed inside box body 1. The holding slot 3 is a groove-shaped structure, integrally injection molded, used to hold the supporting sponge layer 4. The supporting sponge layer 4 is made of high-density polyurethane sponge with a density of 40kg / m³, possessing excellent breathability, a resilience rate ≥90%, and a compression set of ≤3% after a 72-hour compression test. Furthermore, the top surface of the supporting sponge layer 4 has placement slots 6, arranged in 12 groups. Each placement slot measures 20mm × 15mm × 3mm, larger than common chip sizes, accommodating various chip specifications. Inside the box 1, below the storage compartment 3, is a color-changing desiccant 10 made of silica gel color-changing desiccant beads with a particle size of 2-3mm. The initial color is blue, turning pink after absorbing moisture, with a moisture absorption rate ≥35% (25℃, RH=90%), a common material. A base plate 11 is fixedly installed on the bottom of the box 1. The base plate 11 is made of 3mm thick PC endurance board, providing good impact resistance. An observation window 14 is embedded in the surface of the base plate 11. The observation window 14 is made of transparent acrylic sheet with a light transmittance of 92% and a thickness of 2mm. Through the color-changing desiccant 10 and the observation window 14, when the box lid 2 is closed, the color-changing desiccant 10 can absorb moisture from inside the box 1, preventing moisture from affecting chip storage. Simultaneously, the color-changing desiccant 10 changes color after saturation, which users can easily observe through the observation window 14 to determine replacement time. Testing shows that the color-changing visibility distance can reach 3 meters, improving ease of use.

[0027] Please see Figure 1 and Figure 2The top surface of the box body 1 is hinged to the lid 2 using 304 stainless steel hinges. The hinges are 2mm thick and have undergone 100,000 opening and closing tests without damage. Inside the lid 2, 12 pressure posts 5, made of ABS engineering plastic, are fixedly installed on the top surface. These posts correspond one-to-one with the placement slots 6. Rubber posts 7, made of Shore A 30A silicone rubber, are fixedly bonded to the bottom surface of the pressure posts 5. The distance between the bottom surface of the rubber posts 7 and the bottom surface of the placement slots 6 is designed to be 80% of the chip thickness, facilitating stable chip clamping and preventing chip movement. When the chip is placed in the placement slots 6 and the lid 2 is closed, the rubber posts 7 hold the chip in place. Vibration tests show that under a vibration environment of 5-50Hz and 1g acceleration, the chip displacement is <0.5mm, preventing the chip from wobbling. The flexible structure of the supporting sponge layer 4 and rubber pillar 7 can buffer and dampen shocks. The buffering efficiency of the supporting sponge layer 4 is ≥85%, which avoids damage to the chip caused by vibration during movement. At the same time, after opening the cover 2, the rubber pillar 7 automatically leaves the chip, completing the fixation and release. The fixation and release of the chip are very convenient, further improving the ease of use.

[0028] Please see Figure 1 and Figure 3 The front of the box body 1 is fixedly connected to the lid 2 by spring latches 15. There are two sets of spring latches 15, which are made of stainless steel and have a latch pull force of ≥50N. This is a common locking structure and will not be described in detail here. After testing, the latches did not loosen or become damaged when subjected to an external force of 100N.

[0029] Please see Figure 1 and Figure 3 Four sets of four feet 13 are fixedly installed at the corners of the bottom surface of the box body 1. These feet are made of rubber with a Shore A hardness of 60A and are 15mm high, providing a certain degree of shock absorption. In a drop hammer impact test, under the impact of a 1kg weight from a height of 20cm, the internal vibration transmission rate of the box body is <30%, further improving the shock absorption effect. At the same time, the surface of the feet 13 is roughened to a surface roughness of Ra6.3, with a static friction coefficient ≥0.8 with the tabletop, increasing friction during placement and thus improving stability.

[0030] Please see Figure 1 and Figure 4 The base plate 11 is fixedly connected to the bottom surface of the box 1 by fixing screws 12. The fixing screws 12 are M3×10 stainless steel cross screws, and there are four sets. The base plate 11 has screw holes 16 on its surface for the fixing screws 12 to pass through. The bottom surface of the base plate 11 has a threaded blind hole with a depth of 8mm that is threaded to engage with the fixing screws 12. The fixing screws 12 pass through the screw holes 16 and enter the threaded blind hole, and are threaded to engage with the threaded blind hole to fix the base plate 11. The screw tightening torque is 1.2N・m.

[0031] Please see Figure 1 The bottom surface of the box 1 has a bottom opening 9, which is 80mm×60mm in size, smaller than the bottom plate 11 (100mm×80mm). This makes it easy to open the bottom plate 11 to pour out the color-changing desiccant 10 and refill it. The entire operation can be completed by one person within 1 minute.

[0032] Please see Figure 1 The bottom surface of the holding tank 3 is provided with ventilation holes 8. The ventilation holes 8 are 2mm in diameter and are densely and evenly distributed in a regular hexagonal array with equal spacing. The opening rate is 20%. The ventilation holes 8 facilitate airflow. According to the test, the air flow rate can reach 0.5m / s, which facilitates the absorption and removal of moisture in the box 1 by the color-changing desiccant 10, so that the relative humidity in the box can be controlled below 30%RH.

[0033] The implementation principle of this embodiment is as follows: Chip storage and fixation: Place the chip into the placement slot 6 of the supporting sponge layer 4, close the cover 2, and the pressure post 5 on the top surface of the cover 2 will drive the rubber post 7 to press down. By utilizing the elastic contact between the rubber post 7 and the chip, the chip is firmly fixed in the placement slot 6, effectively preventing the chip from being damaged by shaking during transportation or movement. Moisture-proofing: When the lid 2 is closed, a relatively sealed space is formed inside the box 1. The color-changing desiccant 10 below the holding slot 3 comes into full contact with the air inside the box through the vent holes 8 on the bottom of the holding slot 3, continuously absorbing moisture. As the amount of moisture absorbed increases, the color-changing desiccant 10 gradually changes from blue to pink. Users can visually observe the color change through the observation window 14 on the base plate 11. When the discolored area exceeds 50%, it can be determined that the desiccant needs to be replaced to ensure that the humidity inside the box is always within the range suitable for chip storage.

[0034] Shockproof protection: The flexible materials of the supporting sponge layer 4 and rubber pillars 7 can effectively absorb and buffer external forces when subjected to vibration or impact. The supporting sponge layer 4 can disperse the impact force, while the rubber pillars 7 reduce the direct force on the chip through elastic deformation. At the same time, the rubber feet 13 on the bottom of the housing 1 further isolate external vibrations. The three-layer shockproof structure works together to provide comprehensive shockproof protection for the chip. Easy maintenance: When it is necessary to replace the color-changing desiccant 10, simply use a screwdriver to unscrew the fixing screw 12, remove the base plate 11, and easily pour out the expired desiccant and refill it. The spring lock 15 between the box body 1 and the lid 2 facilitates quick opening and closing. The overall operation is simple and convenient, effectively improving the ease of use and maintenance efficiency of the storage box. This utility model features an integrated design that combines moisture-proof, shock-proof, and convenient maintenance. Compared to traditional chip storage boxes, it offers improved moisture protection, enhanced shock resistance, and shorter maintenance time, making it suitable for the storage and transportation of precision components such as electronic chips and integrated circuits.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
