Description

Technical Field

[0001] This utility model belongs to the field of placement rack technology, and more specifically, it relates to a flexible circuit board placement rack. Background Technology

[0002] Flexible printed circuit boards (FPCBs), also known as flexible circuit boards or simply "flexible boards," are printed circuits made from flexible insulating substrates. Flexible circuits offer excellent electrical performance, meet the design needs of smaller and higher-density installations, and also help reduce assembly steps and enhance reliability. FPCBs are the only solution to meet the miniaturization and mobility requirements of electronic products. FPCBs can greatly reduce the size and weight of electronic products, and are suitable for the development of electronic products towards high density, miniaturization, and high reliability.

[0003] After circuit boards are manufactured, they need to be stored using racks. However, existing racks typically lack the ability to evacuate the air inside, causing the circuit boards to come into contact with oxygen and moisture in the air during storage, leading to oxidation and moisture absorption of the electronic components. Therefore, this paper studies and improves upon existing structures and shortcomings to provide a flexible circuit board rack with greater practical value. Utility Model Content

[0008] Furthermore, a cabinet door is rotatably connected to one side of the main frame via a hinge, and a magnetic sealing ring is fixedly adhered to one side of the cabinet door.

[0009] Furthermore, the main frame has a mounting groove on the side near the cabinet door, and a magnetic ring is fixedly connected to the inner side of the mounting groove. The magnetic ring and the magnetic sealing ring attract each other.

[0010] Furthermore, a control panel is fixedly embedded on one side of the main frame, and the vacuum pump is connected to the control panel via wires.

[0011] Furthermore, an air inlet is provided on one side of the main frame, and a vent valve is fixedly installed on the inner side of the air inlet. The vent valve is connected to the control panel via a wire.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a flexible circuit board placement rack, including a main frame 1. The top side of the main frame 1 is provided with an air extraction hole 2. A vacuum pump 3 is fixedly installed on the top side of the main frame 1. The input end of the vacuum pump 3 is fixedly connected to the inner side of the air extraction hole 2. Multiple sets of connecting grooves 4 are provided at equal intervals on both sides of the inner wall of the main frame 1. The inner sides of the two sets of connecting grooves 4 located on the same horizontal line of each set are slidably connected to a placement plate 5 that can be used to place circuit boards.

[0024] A baffle 6 is fixedly installed on the top side of the placement plate 5 to prevent the circuit board on the placement plate 5 from falling off the placement plate 5 due to inertia after the placement plate 5 is moved.

[0025] The baffle 6 has a slot on one side, which allows the placement plate 5 and the baffle 6 to move easily.

[0026] The placement plate 5 is provided with multiple sets of vent holes to prevent the placement plate 5 from obstructing the vacuum pump 3 and to increase the vacuum pump 3's vacuuming efficiency.

[0027] The main frame 1 is connected to a cabinet door 7 by a hinge on one side. A magnetic sealing ring 8 is fixedly attached to one side of the cabinet door 7 to prevent outside air from entering the main frame 1 through the junction of the cabinet door 7 and the main frame 1.

[0028] The main frame 1 has an installation groove on the side near the cabinet door 7. A magnetic ring 9 is fixedly connected to the inner side of the installation groove. The magnetic ring 9 and the magnetic sealing ring 8 attract each other, which can realize the convenient connection between the cabinet door 7 and the main frame 1.

[0029] A control panel 10 is fixedly installed on one side of the main frame 1. The vacuum pump 3 is connected to the control panel 10 through a wire, which allows for convenient control of the vacuum pump 3. At the same time, a vacuum gauge connected to the control panel 10 can be installed inside the main frame 1 to detect whether the main frame 1 is in a vacuum state.

[0030] The main frame 1 has an air inlet on one side, and a ventilation valve 11 is fixedly installed on the inner side of the air inlet. The ventilation valve 11 is connected to the control panel 10 through a wire to prevent the cabinet door 7 from being tightly adhered to the main frame 1 due to the vacuum environment inside the main frame 1, which would prevent the cabinet door 7 from being opened.

[0031] The working principle of this embodiment is as follows: When it is necessary to place the circuit board, connect the vacuum pump 3 and the vent valve 11 in the product to an external power source, open the cabinet door 7 and pull out the baffle 6 and the placement plate 5, place the circuit board on the placement plate 5 and push the placement plate 5 back into the main frame 1, and then close the cabinet door 7. At this time, the cabinet door 7 is stably connected to the main frame 1 under the attraction of the magnetic sealing ring 8 and the magnetic ring 9. Start the vacuum pump 3 to evacuate the main frame 1 to prevent the circuit board from getting damp and oxidized. When it is necessary to take out the circuit board, the vent valve 11 needs to be opened first to allow outside air to enter the main frame 1 to prevent the cabinet door 7 from being unable to open due to the pressure difference between the inside and outside of the main frame 1.

[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
