Description

Technical Field

[0001] This utility model relates to the field of circuit board storage technology, and in particular to a circuit board storage cabinet. Background Technology

[0002] In the field of modern electronic equipment manufacturing and repair, circuit boards (PCBs) are a core component widely used in communication equipment, consumer electronics, industrial control, and many other industries. PCBs typically require temporary storage during production, testing, transportation, and storage. However, traditional storage methods often involve simple stacking or disorderly placement. These methods lack effective separation and fixing structures, making PCBs prone to sliding or even falling off during handling or storage due to external forces (such as collisions or vibrations), resulting in quality problems such as scratches on the PCB surface, component damage, or short circuits.

[0003] To address this, we designed a storage cabinet for circuit boards. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model discloses a storage cabinet for circuit boards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A circuit board storage cabinet includes a cabinet body with an open front and a fixed frame horizontally disposed in the middle of the cabinet's internal cavity, dividing the cabinet's internal cavity into upper and lower storage chambers. The bottom surface of the storage cavity is provided with a lower partition, and the top surface of the lower partition is provided with multiple lower partition grooves evenly spaced along the left and right direction; The storage cavity is provided with an upper partition at the top, and the top surface of the upper partition is provided with multiple upper partition grooves evenly spaced along the left and right direction. The lower partition groove and the upper partition groove are arranged in a one-to-one correspondence to form a storage single cavity.

[0006] Furthermore, the lower partition includes a lower rectangular frame, the top of the inner cavity of the lower rectangular frame is provided with a flow guide plate, and the upper surface of the flow guide plate is provided with a plurality of lower partition strips evenly spaced along the left and right direction, and a lower partition groove is formed between two adjacent lower partition strips. The lower partition bar extends to the outer side of the flow guide plate at both ends and is connected to the front and rear side rods of the lower rectangular frame.

[0007] Furthermore, a top-protruding limiting roller is embedded in the top of the front rod of the lower rectangular frame, and the limiting roller is located in front of the lower partition bar.

[0008] Furthermore, the rear half of the lower rectangular frame is provided with a support roller with a protruding top.

[0009] Furthermore, the upper partition includes an upper rectangular frame, and the top surface of the upper rectangular frame is provided with a plurality of upper partition strips evenly spaced along the left and right direction, and the front and rear ends of the upper partition strips are respectively connected to the front and rear side rods of the upper rectangular frame.

[0010] Furthermore, the front sections of the rods on both the left and right sides of the fixed frame are provided with bidirectional screws, and the middle part of the bidirectional screws is rotatably connected to the fixed frame, and the upper and lower threaded parts are respectively threaded with the corresponding rectangular frame. The fixed frame has guide rods on the rear sections of the rods on both the left and right sides, and the upper and lower sections of the guide rods slide in cooperation with the corresponding rectangular frames.

[0011] Furthermore, the cabinet body has double-groove slide rails at the bottom and top of the open end, and two cabinet doors are provided between the two double-groove slide rails, with each cabinet door corresponding to and slidingly engaging with the front and rear grooves of the double-groove slide rails.

[0012] Furthermore, the cabinet door includes a sliding frame and a transparent door panel disposed inside the sliding frame.

[0013] Furthermore, the lower partition is inclined in the front-to-back direction, and the front end is higher than the rear end.

[0014] Furthermore, the lower separator has an inclination angle of 1-3°.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up corresponding upper and lower partition slots, an independent storage cavity is formed, allowing circuit boards to be stored vertically, avoiding sliding, collision, or even falling problems caused by stacking, and significantly improving storage safety; 2. The inclined design of the lower partition or the setting of the limiting roller effectively prevents the circuit board from accidentally sliding out. Furthermore, the limiting roller and the support roller work together to improve the ease and smoothness of operation. 3. The bidirectional screw and guide rod structure allows for height adjustment of the upper and lower partitions, thus adapting to the storage needs of circuit boards of different heights and enhancing the versatility and flexibility of the equipment; 4.

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if terms such as "upper", "lower", "front", "rear", "left", "right" indicate orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention. It should be understood that if terms such as "end", "side", "end portion", "side part", "lateral", "longitudinal", etc. indicate orientation or positional relationship, they are only corresponding to the length and width of the corresponding component. That is, "end" indicates the head and tail area in the length direction of the corresponding component, and "side part" indicates the head and tail area in the width direction of the corresponding component. They are used for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation.

[0019] Example 1, in conjunction with Appendix Figure 1-2 A circuit board storage cabinet includes a cabinet body 1 with an open front and a fixed frame 2 horizontally disposed in the middle of the inner cavity of the cabinet body 1, which divides the inner cavity of the cabinet body 1 into upper and lower storage cavities. Specifically, cabinet 1 is constructed by welding a frame and a skin, with the lower side of the frame extending downwards to support the ground.

[0020] Furthermore, the top and bottom of the frame taper backward, and double-groove slide rails 9 are installed at the taper positions. Two cabinet doors 10 are provided between the two double-groove slide rails 9, and the two cabinet doors 10 correspond one-to-one with the front and rear slide rails of the double-groove slide rails 9 for sliding cooperation.

[0021] Specifically, the width of the cabinet door 10 is slightly greater than half the length of the double-groove slide rail 9, that is, when the cabinet door 10 is closed, the inner sides of the two cabinet doors 10 overlap to achieve a sealing effect.

[0022] Furthermore, to facilitate observation of the storage conditions within the storage compartment, the cabinet door 10 includes a sliding frame 101 and a transparent door panel 102 located inside the sliding frame 101.

[0023] The bottom surface of the storage cavity is provided with a lower partition 3, and the top surface of the lower partition 3 is provided with multiple lower partition grooves 4 evenly spaced along the left-right direction. As needed, to prevent the circuit board from shifting outwards due to accidental collisions with the cabinet 1, the lower partition 3 is inclined along the front-back direction, with the front end higher than the rear end. Preferably, the inclination angle of the lower partition 3 is 1-3°. In this embodiment, the inclination angle of the lower partition 3 is designed to be 2°.

[0024] The storage cavity is provided with an upper partition 5 at the top, and the top surface of the upper partition 5 is provided with multiple upper partition grooves 6 evenly spaced along the left and right directions; The lower partition groove 4 and the upper partition groove 6 are arranged in a one-to-one correspondence to form a storage single cavity. That is, the storage cavity has multiple mutually spaced single cavities along the left and right direction, which are used to vertically store circuit boards.

[0025] In this embodiment, the height of the storage cavity is higher than the height of the circuit board. Preferably, the height of the storage cavity is 4-6 mm higher than the height of the circuit board. It should be noted that the height of the upper partition 52 is greater than the difference between the height of the storage cavity and the height of the circuit board.

[0026] In one possible implementation, the lower partition 3 includes a lower rectangular frame 31, with a flow guide plate 32 at the top of the inner cavity of the lower rectangular frame 31. The upper surface of the flow guide plate 32 is provided with a plurality of lower partition strips 33 evenly spaced along the left and right direction, and a lower partition groove 4 is formed between two adjacent lower partition strips 33. That is, the bottom of the circuit board can be supported by the flow guide plate 32, and the lower partition strips 33 on both sides can limit the two sides of the bottom of the circuit board.

[0027] Furthermore, the width of the lower partition groove 4 (the distance between two adjacent lower partition strips 33) is greater than the thickness of the circuit board substrate. In this embodiment, the width of the lower partition groove 4 is 1.5~2mm greater than the thickness of the circuit board substrate. This ensures smooth insertion and removal of the circuit board and effectively limits the left and right movement of the bottom of the circuit board.

[0028] To improve overall strength, both ends of the lower spacer 33 extend to the outside of the flow guide plate 32 and are connected to the front and rear side rods of the lower rectangular frame 31; that is, the middle of the lower spacer 33 is connected to the flow guide plate 32 (e.g., by welding), and both ends are connected to the lower rectangular frame 31 (e.g., by welding). This effectively improves the strength of the flow guide plate 32 and prevents deformation of the flow guide plate 32. Preferably, the flow guide plate 32 is made of steel plate with a thickness of 0.5-1mm.

[0029] In one possible implementation, the upper partition 5 includes an upper rectangular frame 51, and a plurality of upper partition strips 52 are evenly spaced on the top surface of the upper rectangular frame 51 in the left-right direction, and the front and rear ends of the upper partition strips 52 are respectively connected to the front and rear side rods of the upper rectangular frame 51.

[0030] Example 2, in conjunction with Appendix Figure 3-5 A circuit board storage cabinet differs from Embodiment 1 in that the lower partition 3 is horizontally positioned to achieve the same effect as the lower partition 3 in Embodiment 1. A top-protruding limiting roller 34 is embedded in the top of the front rod of the lower rectangular frame 31, and the limiting roller 34 is located in front of the lower partition 33. This allows the limiting roller 34 to block the circuit board; the circuit board must overcome gravity and move upwards above the limiting roller 34 before it can shift forward. Therefore, it effectively prevents the circuit board from shifting outwards due to accidental collisions with the cabinet 1. Simultaneously, the limiting roller 34 also provides rolling support for the circuit board during insertion and removal, making the insertion and removal actions smoother.

[0031] Furthermore, the rear half of the lower rectangular frame 31 is provided with a top-protruding support roller 35. That is, the rear section of the stored circuit board is supported by the support roller 35. At this time, under the action of gravity, the front end of the circuit board abuts against the bottom of the lower partition groove 4, and the front end is abutted and limited by the limiting roller 34.

[0032] Example 3, in conjunction with Appendix Figure 3-5 A circuit board storage cabinet is proposed. In Embodiments 1 and 2, the storage cavity height is fixed, which can only be used for storing circuit boards of a specific height, resulting in significant limitations. Therefore, this embodiment differs from Embodiments 1 and 2 in that the installation of the upper partition 5 and the lower partition 3 of the lower storage cavity is optimized, so that the vertical positions of the upper partition 5 and the lower partition 3 of the lower storage cavity can be adjusted according to actual needs to adapt to the storage of circuit boards of different heights.

[0033] The front sections of the rods on both the left and right sides of the fixed frame 2 are provided with bidirectional screws 7, and the middle part of the bidirectional screws 7 is rotatably connected to the fixed frame 2, and the upper and lower threaded parts are respectively threaded with the corresponding rectangular frame. Guide rods 8 are provided on the rear sections of the rods on both the left and right sides of the fixed frame 2, and the upper and lower sections of the guide rods 8 are respectively slidably engaged with the corresponding rectangular frames.

[0034] Because the bidirectional screw 7 is relatively close to the skin of the cabinet 1, the operating space is small. In this embodiment, a hexagonal hole is provided at the end of the bidirectional screw 7 for use with a universal wrench, which drives the bidirectional screw 7 to rotate. Alternatively, a micro motor can be installed at the end of the bidirectional screw 7 to drive its rotation, causing the corresponding lower partition 3 and upper partition 5 to move relative to or away from each other. This allows the height of the upper and lower storage cavities to increase or decrease synchronously, accommodating the storage of circuit boards of different heights. The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims in this utility model, and no reference numerals in the claims should be regarded as limiting the content of the claims.
