Description

Technical Field

[0001] This utility model relates to the field of electronic component packaging and transportation technology, and in particular to a PCB board turnover box that is easy to stack and handle. Background Technology

[0002] PCB turnover boxes are specialized containers used in the electronics manufacturing industry for storing, transporting, and turning over printed circuit boards. Their core function is to protect PCB boards from static electricity, dust, and physical impact damage through anti-static design, while improving space utilization and logistics efficiency through structured design.

[0003] Existing PCB board turnover boxes use EVA foam as an inner lining to protect the PCB board. However, the EVA foam lining is prone to aging and deformation, and during transportation, it is easy for component leads to bend or the board surface to be scratched due to shaking, which cannot effectively protect the PCB board.

[0004] Addressing the issue that existing PCB turnover boxes, which use EVA foam as an inner lining for PCB protection, are prone to aging and deformation, and easily suffer from component pin bending or board surface scratches due to shaking during transportation, thus failing to effectively protect the PCB, this new PCB turnover box features a multi-directional fixed shock-absorbing structure. This structure effectively clamps and protects the PCB inside the turnover box, and when the turnover box vibrates, it effectively absorbs and mitigates the vibration, preventing it from being transmitted to the PCB, thus significantly improving the protection of the PCB during turnover. Utility Model Content

[0005] To overcome the problem that existing PCB board turnover boxes use EVA foam as an inner lining to protect PCB boards, the EVA foam lining is prone to aging and deformation, and during transportation, it is easy for component leads to bend or the board surface to be scratched due to shaking, thus failing to effectively protect the PCB board.

[0006] The technical solution of this utility model is as follows: a PCB board turnover box that is easy to stack and transport, including a turnover box body, a load-bearing airbag, an air vent, a honeycomb shock-absorbing hole, an adjusting bolt, a silicone limiting plate, a limiting base, a positioning component, and a fixing component. The load-bearing airbag is provided on the inner bottom surface of the turnover box body. The load-bearing airbag is filled with inert gas. The surface of the load-bearing airbag has multiple sets of air vents. The interior of the load-bearing airbag has honeycomb shock-absorbing holes. An adjusting bolt is provided on one side of the turnover box body. The adjusting bolt passes through one side of the turnover box body. A silicone limiting plate is provided at one end of the adjusting bolt. A limiting base is provided on the outer side of the adjusting bolt. A positioning component is provided on the surface of the turnover box body. A fixing component is provided on the bottom surface of the turnover box body. A ventilation hole is provided on the outer side of the turnover box body.

[0007] Preferably, the PCB board is placed and supported by a load-bearing airbag. When the load-bearing airbag is under force, some inert gas is discharged through the air vent to form a buffer space. The pressure is dispersed by the honeycomb shock-absorbing holes. The extension position of the silicone limiting plate is adjusted by the adjusting bolt. The adjusting bolt is limited and fixed by the limiting base. The side of the placed PCB board is limited and fixed by the silicone limiting plate. Multiple turnover box bodies are positioned and stacked by the positioning component. The PCB board is pressed and positioned from above by the fixing component. The interior of the turnover box body is ventilated by the ventilation port.

[0008] Preferably, the positioning component includes limiting holes and positioning posts. Limiting holes are provided at the four corners of the top surface of the turnover box body, and positioning posts are provided at the four corners of the bottom surface of the turnover box body.

[0009] Preferably, the fixing components include spring telescopic rods, flexible shock-absorbing plates, and silicone positioning feet. The bottom surface of the turnover box body is provided with spring telescopic rods, and multiple sets of spring telescopic rods are provided. The bottom end of the spring telescopic rods is provided with flexible shock-absorbing plates, and the bottom surface of the flexible shock-absorbing plates is provided with silicone positioning feet.

[0010] Preferably, the outer side of the main body of the turnover box is provided with a mounting base and a collision protection block, the outer side of the main body of the turnover box is provided with a mounting base, and the inside of the mounting base is provided with a collision protection block.

[0011] Preferably, the bottom surface of the main body of the turnover box at the bottom is provided with a rotating base, and multiple sets of rotating bases are provided, with casters on the bottom surface of the rotating base.

[0012] Preferably, the outer wall surface of the turnover box is provided with an installation plate, and a humidity indicator card is provided on one side of the installation plate.

[0013] As a preferred option, multiple sets of ventilation openings are provided, and the ventilation openings are square with a diameter of 5~8mm.

[0014] The beneficial effects of this utility model are:

[0015] Existing PCB turnover boxes use EVA foam as an inner lining to protect the PCB board. However, EVA foam lining is prone to aging and deformation, and during transportation, shaking can easily cause component leads to bend or the board surface to be scratched, thus failing to provide effective protection for the PCB board. This new PCB turnover box, through the setting of a multi-directional fixed shock-absorbing structure, can effectively clamp and protect the PCB board inside the turnover box. At the same time, when the turnover box vibrates, it can effectively absorb and release the vibration, preventing it from being transmitted to the PCB board, thus effectively improving the protection of the PCB board during turnover.
