Description

Technical Field

[0001] This utility model relates to the technical field of PCB board processing tools, and in particular to a PCB board storage device. Background Technology

[0002] In the electronics manufacturing industry, PCB boards are the core carriers of electronic components, and their storage is crucial to product quality and production efficiency. As electronic products develop towards miniaturization and integration, the production scale of PCB boards continues to expand, placing higher demands on the capacity and convenience of storage devices. Traditional PCB board storage devices mostly adopt multi-layer stacked structures, increasing the number of layers to improve space utilization in order to meet the storage needs of a large number of PCB boards.

[0003] Traditional PCB storage devices, with their fixed heights for the support plates and storage boxes, make it extremely inconvenient to retrieve PCBs stored at heights. Operators must use ladders, lifting platforms, and other auxiliary tools to access these PCBs, which not only consumes a lot of time and manpower but also poses risks such as tool slippage and operator loss of balance, easily leading to accidents like falls from heights. Statistics show that approximately 30% of workplace injuries in electronics manufacturing workshops caused by accessing materials at heights are related to the operation of PCB storage devices. Furthermore, frequent use of auxiliary tools reduces production efficiency and increases operating costs for businesses. Therefore, these problems need to be addressed. Utility Model Content

A pull groove is opened on one side of the box, and a first support groove is opened at equal intervals at the bottom of the pull groove.

[0007] Preferably, the storage box has multiple second support slots on both sides inside, which are adapted to the first support slot, and each second support slot is provided with a spring for fixing the PCB board.

[0019] 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.

[0020] Example: See Figure 1-4 This utility model discloses a PCB board storage device, including a support frame 1. A base plate 5 is fixedly connected to the bottom of the support frame 1, which allows the device to be placed stably on the ground to avoid tipping over due to instability. The base plate 5 is equipped with multiple wheels 6, which improves the mobility and flexibility of the device, allowing the PCB boards to be easily transferred between different locations such as production lines and warehouses. A mounting plate is provided on the top of the base plate 5, which is welded to the support frame 1. Multiple fixing blocks 9 are vertically and equidistantly welded to the inner wall of the support frame 1, which allows the support plates 2 to be firmly installed on the support frame 1, ensuring the stability of the device structure. Each fixing block 9 is equipped with a support plate 2, which allows for layered storage of storage boxes 4, making full use of the device space and improving space utilization. The storage boxes 4 are placed on the support plates 2, and a lifting component is provided on one side of the top of the mounting plate.

[0021] In this utility model, two hinged hinges 11 are fixed to one side of the bottom of the storage box 4. A box pull plate 10 is hinged to one side of the storage box 4 via the two hinged hinges 11. A pull groove is opened on one side of the box, and first support grooves are equally spaced at the bottom of the pull groove. The box pull plate 10 facilitates the convenient opening and closing of the storage box 4, improving the efficiency of operators in picking up and putting down PCB boards. Multiple second support grooves that match the first support grooves are opened on both sides of the inside of the storage box 4. Each second support groove is provided with a spring piece 12 for fixing the PCB board. The spring piece 12 ensures that the PCB board is fixed in position inside the storage box 4, avoiding collisions between PCB boards or friction with the inner wall of the storage box 4. Multiple connecting seats are welded to the side wall of the box pull plate 10 and the side wall of the storage box 4. Bolts 13 are screwed together between the connecting seats for fixing. The storage box 4 effectively protects the PCB board from external impacts, dust, moisture and other factors. The lifting component includes a threaded rod 7 inserted between multiple support plates 2. The support plates 2 are threadedly connected to the threaded rod 7. A motor is coaxially connected to the bottom of the threaded rod 7. A guide rod 8 slides between the multiple support plates 2. The bottom end of the guide rod 8 is fixed to the mounting plate. The lifting component allows the support plates 2 to be accurately raised or lowered to the required position. Multiple slots are opened on the support plates 2. The top of the storage box 4 is equipped with a connector 3. The storage box 4 is snapped onto the support plates 2 through the connector 3. The connector 3 facilitates the installation and disassembly of the storage box 4, and facilitates the individual cleaning, maintenance or replacement of the storage box 4.

[0022] Working Principle: When using this invention, the device can be easily moved to a designated location via the wheels 6 at the bottom of the base plate 5. The design of the wheels 6 reduces the friction between the device and the ground, allowing the device to move flexibly between different work areas and meet the transportation needs of PCB boards between production lines, warehouses, and other locations. Once the device reaches the designated location, the PCB board is placed into the storage box 4. The second support grooves on both sides of the storage box 4 cooperate with the first support groove at the bottom to provide support space for the PCB board. When the PCB board is placed in, the spring piece 12 in the second support groove generates elasticity. The deformation applies pressure to the PCB board, firmly fixing it to prevent it from shaking, shifting, or colliding during storage and handling, ensuring safe storage. The storage box 4 is then secured to the slot on the support plate 2 via the top connector 3, achieving a stable connection. Multiple support plates 2 are fixed to the inner wall of the support frame 1 by fixing blocks 9, arranged vertically at equal intervals, allowing the storage boxes 4 to be stored in layers, fully utilizing the internal space of the device and increasing storage capacity. If access to a higher storage box 4 is required, the various electrical components in this application are respectively connected to the external... The control equipment is electrically connected, activating the lifting mechanism. The threaded rod 7, coaxially connected to the motor at the bottom, begins to rotate under motor drive. Since the support plate 2 is threadedly connected to the threaded rod 7, the rotational motion of the threaded rod 7 is converted into the linear lifting motion of the support plate 2. Simultaneously, the guide rod 8, inserted between multiple support plates 2, provides guidance for the lifting of the support plates 2, ensuring that the support plates 2 move smoothly in the vertical direction without tilting or swaying. By controlling the direction and number of rotations of the motor, the height of the support plates 2 can be precisely adjusted, raising and lowering the storage box 4 to a suitable position for easy access by operators. After the storage box 4 is placed in place, the box pull plate 10, which is hinged to the storage box 4 via the hinge hinge 11, can rotate around the hinge point. When closing the box pull plate 10, it is pressed against the storage box 4 so that the side wall of the box pull plate 10 is aligned with the connecting seat on the side wall of the storage box 4. Then, the bolts 13 between the connecting seats are tightened to firmly fix the box pull plate 10, ensuring that the storage box 4 is sealed and preventing external factors such as dust and moisture from affecting the quality of the PCB board. Finally, when opening, the bolts 13 are loosened and the box pull plate 10 is rotated to easily store and retrieve the PCB board. This concludes the use of the PCB board storage device.

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.
