Description

Technical Field

[0001] The utility model relates to the technical field of circuit board storage, and more specifically to a flexible circuit board storage device. Background Art

[0002] A flexible circuit board is a thin, soft electronic circuit board that is usually composed of a flexible substrate and conductive copper foil. Compared with traditional rigid circuit boards, flexible circuit boards have better flexibility and bending properties, and can adapt to complex three-dimensional shapes and space constraints. They are often used in electronic devices that need to be lightweight, thin, and flexible, such as smartphones, tablets, wearable devices, etc. Flexible circuit boards also have good high temperature resistance and chemical corrosion resistance, and are suitable for applications in some special environments. The existing flexible circuit board needs to be put into the temporary storage machine from the feed channel, and then the flexible circuit board falls from a high place to the bottom of the temporary storage box. At this time, the personnel starts the motor to drive the gear lever to smooth the flexible circuit board, and then starts the second rubber roller at the bottom of the box to drive the flexible circuit board that falls into the bottom of the box to move and be transported out through the discharge channel. However, in the above technical solution, the flexible circuit board must fall from the upper part of the temporary storage machine to the lower part. In this process, the exposed copper sheet on the outside of the flexible circuit board may be scratched, resulting in poor contact.

[0003] In response to the above problems, regarding the technical problem that when the existing flexible circuit board storage device is stored, the circuit board falls directly from the upper part to the lower part, and in this process, the exposed copper sheet on the outside of the flexible circuit board may be scratched, resulting in poor contact, after a lot of searches, a flexible circuit board storage device with patent application number 202223030327.2 was found, which belongs to the technical field of circuit board storage devices, including: a storage box, a feed port and a discharge port are respectively provided at the upper and lower ends of one side of the storage box, a screw rod is rotatably installed on one side of the storage box, and a motor is connected to the top of the screw rod, a first slider is screwed on the screw rod body in the storage box, and a receiving plate is fixed on one side of the first slider, but the technical solution provided by the patent has the following problems:

[0004] (1) The utility model aims to reduce the oxygen content inside the storage device, but the flexible circuit board is an electronic component and has high requirements for the oxygen content in the storage environment. When the humidity in the storage space is too high, the metal parts in the electronic components are prone to oxidation reactions, resulting in oxidative corrosion, which may cause problems such as poor circuit connection, blocked signal transmission or short circuit;

[0005] (2) In the utility model, the humidity inside the drying box is reduced by placing a desiccant in the drying box, but the inlet and outlet are not provided with corresponding sealing structures, so that the internal dehumidification effect of the device is poor when it is in use. If the humidity is too high, the electronic components will be corroded, thus affecting the use.

[0006] The utility model can further improve the sealing performance of the box body and reduce the oxygen content inside the box body when in use, thereby preventing the electronic components from being corroded and oxidized. Utility Model Content

[0008] A further preferred solution is that a support block is provided at the bottom of the lower drawer relative to the inner wall, there are two support blocks, and the drawer is placed above the support blocks.

[0009] A further preferred solution is that a limit block is provided on the inner wall of the box body, and the limit block is located between the top of the lower drawer and the bottom of the upper drawer, one end of the limit block is fixedly connected to the side wall of the box body, and the other end is a free end and contacts the outer wall of the drawer.

[0010] A further preferred solution is that a hole is opened in the side wall of the box body, a sealing strip is arranged on the side wall of the hole, and the hole matches the outer diameter of the hose.

[0011] A further preferred solution is that a sealing strip is provided on the inner edge of the outer plate of the material holding drawer.

[0012] A further preferred solution is that a cover body is provided on the feed port, a raised portion is provided on the inner side of the cover body facing outward, the raised portion fits in with the feed port, and a sealing strip is provided at the edge of the raised portion.

[0013] A further preferred solution is that magnets are provided on the outer side of the inner plate of the material holding drawer and the inner wall of the box body.

[0014] Beneficial effects:

[0015] 1. By setting up a nitrogen pipe, nitrogen is filled into the box through a hose, and the air inside the box is purged out from the feed port, and then the box is filled with nitrogen, so that the inside of the box is in a low oxygen state for a long time. Since nitrogen is a highly stable gas, it is not easy to react with other substances at normal temperature and pressure. It is an inert gas and has a good protective effect on circuit components;

[0016] 2. By setting a sealing strip to seal the box, it is prevented that air enters the box through the gap during storage, so that the humidity in the air corrodes the flexible circuit board, and at the same time, it is prevented that oxygen in the air enters the box, so that the flexible circuit board undergoes oxidation reaction and causes damage to the flexible circuit board;

[0017] 3. By setting up the electric push rod, limit block and drawer structure, the drawer is raised to the same level as the feed port or slightly lower, and then the flexible circuit board is stored in the drawer, and then the drawer is lowered to the lower drawer, avoiding the problem of damage caused by the flexible circuit board falling directly from a high place during storage;

[0018] 4. In summary, the flexible circuit board storage device can prevent the flexible circuit board from falling from a high place during storage and causing damage, the excessive oxygen content in the storage box causing oxidation of the circuit board, and the poor sealing of the box, causing air to enter the box, resulting in increased humidity and oxygen content in the box, thereby causing the flexible circuit board to be oxidized and corroded, affecting its use, through structures such as electric push rods, drawers, limit blocks, nitrogen tanks, hoses and feed ports.
