Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a printed circuit board temporary storage rack. Background Technology

[0002] The working principle of a circuit board is to use the insulating material on the board base to isolate the conductive copper foil layer on the surface, so that the current flows through various components along a pre-designed route to complete functions such as doing work, amplification, attenuation, modulation, demodulation, and encoding. It provides physical support and electrical connection for electronic components. Essentially, it is an insulating substrate on which conductive lines are made through specific processes. These lines can connect various electronic components (such as resistors, capacitors, integrated circuits, etc.) in a pre-designed way, just like the road system in a city, guiding vehicles (electronic signals and currents) to shuttle between various buildings (electronic components), so that electronic equipment can operate normally.

[0003] When a large number of printed circuit boards are stored together, heat easily accumulates between the boards due to their close arrangement and lack of effective heat dissipation design. As electronic components generate heat during operation or the ambient temperature affects the heat, it cannot be dissipated in time, causing the operating temperature of the printed circuit boards to rise continuously. This not only accelerates the aging of electronic components and shortens their lifespan, but may also cause unstable component performance or even damage due to overheating, seriously affecting the quality of the circuit boards and the reliability of subsequent use. On the other hand, in a normal temporary storage environment, dust in the air is easily adsorbed on the surface of the printed circuit boards, interfering with circuit signal transmission and increasing the probability of electrical faults. It is also not conducive to accurate testing and debugging of the circuit boards. Therefore, this application proposes another technical solution to address this problem. Utility Model Content

Several slides 3 are fixedly installed on the inner walls of the left and right sides of the installation box 2. A storage box 4 is slidably connected inside the slides 3.

[0025] The slide block 3 has a sliding groove inside, and the storage box 4 is slidably connected to the slide block 3 through the sliding groove, which helps the storage box 4 to slide and move inside the slide block 3. The circuit board body 5 is movably connected inside the storage box 4. A rotary motor 6 is fixedly installed on the top of the mounting box 2, and a threaded rod 7 that is rotatably connected to the mounting box 2 is fixedly installed on the output shaft of the rotary motor 6.

The movable block 8 has a threaded groove inside. The movable block 8 is threadedly connected to the threaded rod 7 through the threaded groove, which helps the movable block 8 to move up and down on the outer side of the threaded rod 7. A limit groove is opened on one side of the inner wall of the mounting box 2. The movable block 8 is movably connected to the mounting box 2 through the limit groove, which facilitates the limitation of the movable block 8.

[0031] This printed circuit board temporary storage rack can be used by first opening the sealing door 201, then inserting the circuit board body 5 into the storage box 4 for storage. The storage box 4 can then be pushed into the slide 3 to store multiple circuit board bodies 5. During storage, to prevent excessive moisture inside the mounting box 2 from causing problems with the circuit board bodies 5, the blower 9 can be activated. The blower 9 blows air through the partition 10, dehumidifying the circuit board bodies 5 inside the mounting box 2. Simultaneously, the exhaust fan 13 can be activated, drawing air out of the mounting box 2, allowing air circulation and expelling moisture through the exhaust duct 11. When dust in the air inside the mounting box 2 passes through the dust collection net 15, the dust is absorbed, helping to prevent dust from entering the mounting box 2 and effectively protecting the circuit board bodies 5, greatly improving the device's performance.
