Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a storage rack for single-sided PCB circuit boards. Background Technology

[0002] Printed circuit boards (PCBs) are the core components in electronic devices that enable circuit connections, and their design constantly strives for more compact layouts and more stable performance. Modern PCBs utilize multi-layer stacking technology to transform the originally flat lines into a three-dimensional network, integrating more functional modules within a limited space. Key processes such as microvia fabrication and impedance matching ensure the accuracy of high-speed signal transmission, while optimized copper foil distribution and heat dissipation channels enhance overall reliability. This structure allows PCBs to adapt to diverse needs from consumer electronics to industrial equipment, making them an indispensable basic component in the digital age.

[0003] The design focus of PCB storage racks is to protect circuit boards from environmental damage while improving storage efficiency. Mainstream solutions utilize anti-static materials to construct the frame, preventing electrostatic discharge from damaging sensitive components, and employ a layered, adjustable structure to accommodate PCBs of different sizes. Some high-end models incorporate temperature and humidity monitoring and a sealed design to prevent pad oxidation or moisture intrusion, extending storage life. Their modular nature allows for rapid reconfiguration, meeting the needs of frequent model changes on production lines, making them a key tool for ensuring quality and efficiency in electronic manufacturing.

[0004] Patent document CN211333144U discloses an anti-slip storage rack suitable for PCBs, comprising: a support structure and a base, the base being connected to the support structure, the base including a base bracket, and an anti-slip strip having several grooves on the base bracket. This invention, by providing grooved anti-slip strips on the base bracket, improves the friction of the PCB placed on the base bracket, making it less prone to slipping.

[0005] In the prior art of the aforementioned patent, the PCB board is inserted into the storage rack, and the PCB board is fixed by only using grooves and anti-slip strips to increase the friction between the PCB board and the storage rack. However, this placement method can only be used for temporary storage and cannot achieve temporary movement. If there is a need to move the storage rack briefly, the PCB board may slip off the storage rack during the movement. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-6A storage rack for single-sided PCB circuit boards includes a support base 1, which is L-shaped. An anti-static frame 2 made of anti-static PP material is mounted on the support base 1. The anti-static frame 2 has multiple slots 3. A limit frame 6 is mounted on the vertical section of the support base 1. The limit frame 6 is connected to the support base 1 via an elastic rotating assembly. Locking components for locking the limit frame 6 are provided at both ends of the limit frame 6. The PCB boards 14 to be placed are placed on the anti-static frame 2. Then, by rotating the limit frame 6, it is pressed against the multiple PCB boards 14. The locking components then lock the limit frame 6, preventing it from rotating, thus fixing the limit frame 6. At this time, the multiple PCB boards 14 are stably fixed above the anti-static frame 2 with the cooperation of the slots 3, the top plate 4, and the limit frame 6.

[0020] It is worth mentioning that this storage rack can only be used for PCB boards 14 of the same size in the same batch. If it is used to store PCB boards 14 of different sizes, it cannot fix the smaller PCB boards.

[0021] As a preferred technical solution of this embodiment, the limiting frame 6 is U-shaped and consists of two vertical parts 601 and one horizontal part 602. Multiple pressure rollers 7 are fixedly installed on the horizontal part 602, and annular grooves 8 are provided on the multiple pressure rollers 7. The positions of the pressure rollers 7 and the slots 3 below correspond one-to-one. The pressure rollers 7 on the limiting frame 6 can press on the multiple PCB boards 14 through the annular grooves 8, thereby fixing the PCB boards 14.

[0022] As a preferred technical solution in this embodiment, the contact surface on the antistatic frame 2 for contacting the side of the PCB board 14 is inclined in the direction of the vertical section of the support base 1, and the contact surface on the antistatic frame 2 for contacting the bottom edge of the PCB board 14 is inclined upward in the direction away from the vertical section of the support base 1. A top plate 4 is fixedly installed at the top of the antistatic frame 2, and the inclination angle of the top plate 4 is consistent with the inclination angle of the contact surface on the antistatic frame 2 for contacting the bottom edge of the PCB board 14. The contact surface of the support base 1 for placing the PCB board 14 is inclined, which enables the PCB board 14 to lean against the antistatic frame 2 at an inclination when it is placed, and the top plate 4 above can limit the top of the PCB board 14.

[0023] As a preferred technical solution of this embodiment, the elastic rotation component includes a sleeve shaft 5 fixedly installed on both sides of the support base 1. Two vertical parts 601 on the limiting frame 6 are rotatably connected to the sleeve shaft 5. A torsion spring 13 is provided inside the sleeve shaft 5. One end of the torsion spring 13 is fixedly connected to the sleeve shaft 5, and the other end of the torsion spring 13 is fixedly connected to the limiting frame 6. When the locking component is contacted, the limiting frame 6 will flip upward due to the action of the torsion spring 13, so that the pressure roller 7 leaves the multiple PCB boards 14, thereby facilitating the removal of the PCB boards 14.

[0024] As a preferred embodiment, the locking assembly includes two locking members 9, each consisting of a long segment 901 and a short segment 902. The long segment 901 and the short segment 902 are fixedly connected to form a J-shaped structure. The support base 1 has a first insertion hole 10 and a second insertion hole 11 on both sides. The first insertion hole 10 is positioned above the second insertion hole 11. The short segment 902 is inserted into the first insertion hole 10, and the long segment 901 is inserted into the second insertion hole 11. Pulling the locking member 9 outwards can... Pull the short section 902 out of the first insertion hole 10. At this time, the limit frame 6 can be rotated downward. After the limit frame 6 is fully pressed on the multiple PCB boards 14, release the locking member 9. The locking member 9 can be reset under the action of the spring 12. At this time, under the action of the short section 902 of the locking member 9, the limit frame 6 can be locked. This device can be customized according to the size data of the batch of PCB boards 14, so that under the locking and limiting action of the locking member 9, the pressure roller 7 on the limit frame 6 and the top plate 4 above it can be precisely stuck on the edge of the PCB board 14.

[0025] As a preferred technical solution of this embodiment, a spring 12 is provided inside the second socket 11. One end of the spring 12 is fixedly connected to the inner wall of the second socket 11, and the other end of the spring 12 is fixedly connected to the long section 901. The function of the spring 12 is to realize the reset of the locking member 9 after it is pulled out.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
