Description

Technical Field

[0001] This utility model relates to transfer boxes, and more particularly to a circuit board protection transfer box. Background Technology

[0002] Circuit boards, or PCBs, are typically characterized by their brittleness, susceptibility to edge chipping, and fragile surface circuitry and pads. Therefore, transfer boxes are essential for bulk transport during the production, warehousing, and transportation of PCBs. Traditional PCB transfer boxes are often open-top boxes without partitions or open-top boxes with simple internal space divisions using grids. This traditional design requires stacking PCBs, which leads to direct contact between boards, increasing frictional damage. Furthermore, vibrations during transport (such as forklift movement or assembly line conveyors) exacerbate mechanical damage, causing edge chipping, surface scratches, component lead deformation, and detachment of surface-mount capacitors / resistors. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a circuit board protection transfer box.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is: a circuit board protection transfer box, including a box shell, and the circuit board protection transfer box also includes a movable cover that closes to the opening at the top of the box shell; A top edge is formed at the top opening of the housing shell, and a raised edge is provided upward along the top edge; A limiting groove is formed on the raised edge, and the side of the movable cover has a buckle that can be inserted into the limiting groove; Multiple circuit board protection frames are stacked inside the housing. The circuit board protection frame includes a side frame, and longitudinally and transversely distributed partition ribs are fixed in the inner cavity of the side frame, which divide the inner cavity of the side frame into several circuit board placement slots.

[0005] Preferably, the side frame of the circuit board protection frame is provided with symmetrically arranged easy-to-operate pull holes.

[0006] Preferably, a bottom support ring is fixed at the bottom edge of the inner cavity of the housing, and a bottom support positioning hole is provided on the bottom support ring;

[0007] Each set of circuit board protection frames has a protection frame positioning hole of the same specification as the bottom support positioning hole on the top of the side frame, and a positioning post that can be inserted into the bottom of the side frame to match the protection frame positioning hole and the bottom support positioning hole.

[0008] Preferably, an anti-static rubber pad is laid in the circuit board placement slot, and an anti-static rubber base pad is laid at the bottom of the side frame.

[0009] Preferably, the buckle has a fixing hole and the bottom of the limiting groove has a threaded hole.

[0010] Preferably, a thickened base is formed at the bottom of the housing, and the thickened base is adapted to be inserted into the opening of the raised edge of the adjacent housing.

[0011] Preferably, the four vertices of the raised edge are provided with lifting holes.

[0012] Preferably, reinforcing ribs are formed on the outer wall of the housing.

[0013] Preferably, the box body handles are symmetrically arranged at the lower position near the top edge of the box body.

The circuit board protection racks can provide independent placement space for circuit boards (i.e., circuit board placement slots) and realize the layered placement of circuit boards inside the box shell. Since direct contact between boards is avoided, it can effectively reduce the occurrence of mechanical damage such as edge chipping of bare boards, scratches on surface lines, deformation of component leads, and detachment of surface-mount capacitors / resistors.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] This embodiment discloses a circuit board protection transfer box, the main structure of which includes: a box shell 1, a circuit board protection frame 12, and a movable cover 13.

[0024] First, the structural arrangement of the housing 13 is as follows: Figure 1 and Figure 2 As shown, it is an open box structure, with a thickened base 11 formed at the bottom of the box shell 13; Secondly, the setting of the active cover 13 is as follows: Figure 4 As shown, the movable cover 13 is detachably closed at the top opening of the housing 1. After the circuit board inside the housing 13 is placed, the movable cover 13 can be closed to achieve enhanced protection of the top.

[0025] Considering the stacking requirements of transfer boxes in warehousing and transportation, in order to avoid the design of the movable cover affecting the stacking performance of the transfer boxes, the circuit board protection transfer box disclosed in this embodiment is further heightened on the basis of the top edge 4 formed at the top opening of the box shell 1, that is, a raised edge 5 is provided upward along the top edge 4. Based on the raised edge 5, a limiting groove 9 is formed on the raised edge 5. The side of the movable cover 13 has a latch 14 that can be inserted into the limiting groove 9. When the movable cover 13 is closed at the top opening of the box shell 13, the latch 14 is inserted into the limiting groove 9 one by one, so that the movable cover 13 is closed at the height of the top edge 4. Because the raised edge 5 is raised, there is enough space so that the thickened base 11 of the adjacent stacked box shells 1 can still be smoothly fitted into the opening of the raised edge 5, thereby meeting the stacking requirements of the transfer box in the storage, transportation and other processes of this embodiment.

[0026] As a preferred option, such as Figure 4As shown, a fixing hole 15 is provided on the latch 14, and a threaded hole 10 is provided at the bottom of the limiting groove 9. When the movable cover 13 is closed at the top opening of the housing 13, the fixing hole 15 of the latch 14 and the threaded hole 10 of the limiting groove 9 are aligned vertically. Screws can be locked into the aligned fixing hole 15 and threaded hole 10 together to achieve the anti-detachment closing setting of the movable cover 13. It should be noted that whether to lock the screws is usually selected according to the specific usage requirements of production, warehousing, transportation and other links. If it is necessary to quickly transfer the circuit board inside the housing, the movable cover can usually be closed onto the housing. If long-term storage or transportation is required, the movable cover is usually locked onto the housing with screws.

[0027] Preferably, to facilitate the opening and placement of the movable cover 13, a lifting ring can be provided at the center of the movable cover 13. The lifting ring is hinged to the lifting base. When not in use, it can be laid almost flat, so it will not affect the stacking performance of the thickened base 11 and the raised edge 5.

[0028] Furthermore, the structural arrangement of the circuit board protection frame 12 is as follows: Figure 3 As shown, multiple sets of circuit board protection frames 12 are stacked in the inner cavity of the housing 1, preferably 3-5 sets. If they are too high, it will be difficult to put the circuit board protection frames 12 in or take them out.

[0029] like Figure 3 As shown, the circuit board protection frame 12 has a side frame 121, and longitudinally and transversely distributed partition ribs 122 are fixed in the inner cavity of the side frame 121. The partition ribs 122 divide the inner cavity of the side frame 121 into a number of circuit board placement slots 123.

[0030] Several circuit board placement slots 123 provide independent space for placing circuit boards. Furthermore, the circuit board protection frame 12 is also placed in layers inside the housing 1. Therefore, the circuit board protection transfer box disclosed in this embodiment effectively avoids the situation of stacking circuit boards in traditional turnover transfer boxes. Since there is no direct contact between the boards, friction damage between the boards can be avoided, and the impact of vibration during transportation can be reduced. This effectively reduces mechanical damage phenomena such as bare board edge cracking, surface line scratches, component pin deformation, and chip capacitor / resistor detachment.

[0031] Furthermore, the specific arrangements for the stacking of the circuit board protection frame 12 include: firstly, as shown in the figure... Figure 1 As shown, a bottom support ring 6 is fixed at the bottom edge of the inner cavity of the housing 1, and a bottom support positioning hole 7 is provided on the bottom support ring 6. At the same time, such as Figure 3As shown, each set of circuit board protection frame 12 has a protection frame positioning hole 126 of the same specification as the bottom support positioning hole 7 on the upper part of the side frame 121, and a positioning post 127 that can be inserted into the side frame 121 to match the protection frame positioning hole 126 and the bottom support positioning hole 7.

[0032] Thus, the bottom support ring 6 supports the bottommost circuit board protection frame 12. The positioning pins 127 of the bottommost circuit board protection frame 12 are inserted into the bottom support positioning holes 7. After the bottommost circuit board protection frame 12 is placed, other circuit board protection frames 12 are placed in sequence, so that the positioning pins of the upper layer circuit board protection frame 12 are inserted into the positioning holes of the lower layer protection frame.

[0033] Preferably, to facilitate manual placement of the circuit board protective frame 12 layer by layer, such as Figure 3 As shown, easy-to-operate pull holes 124 are symmetrically provided on the side frame 121 of the circuit board protection frame 12. The easy-to-operate pull holes 124, which have notch and groove structure features, can facilitate manual lifting of the circuit board protection frame 12.

[0034] In summary, the circuit board protection transfer box disclosed in this embodiment has the following technical advantages compared with the prior art: 1) A movable cover was designed for the open box shell, solving the problem of no protection on the top of traditional turnover and transfer boxes; 2) Considering the stacking requirements of transfer boxes in warehousing and transportation, in order to avoid the design of the movable cover affecting the insertion and stacking performance of the thickened base and the box shell below, a raised edge was designed on the basis of the top edge to leave enough space to maintain the space optimization performance of the stacking of transfer boxes.

[0035] 3) The stacked design of multiple circuit board protection frames provides an independent placement space for each circuit board, reducing the displacement space of the circuit boards and reducing the impact of vibration during transportation. In addition, the circuit board protection frames avoid direct contact between the boards, effectively reducing the probability of mechanical damage such as edge chipping of bare boards, scratches on surface circuits, deformation of component leads, and detachment of surface-mount capacitors / resistors.

[0036] Example 2

[0037] This embodiment discloses a circuit board protection transfer box. Based on the structure disclosed in Embodiment 1, to further enhance the protective performance of the circuit board protection frame 12 on the circuit boards placed in the circuit board placement slot 123, such as... Figure 3As shown, an antistatic rubber pad 128 is laid inside the circuit board placement slot 123, and an antistatic rubber base pad 125 is laid at the bottom of the side frame 121. For the antistatic rubber base pad 125, a through hole is opened at the location of the positioning post so that the positioning post 127 has a sufficient length to match the positioning hole.

[0038] The antistatic rubber pad 128 protects the side and bottom walls of the circuit board placement slot 123, reducing the damage caused by the impact between the circuit board and the slot wall of the circuit board placement slot 123. When the circuit board protection rack 12 is stacked, the antistatic rubber bottom pad 125 is located between adjacent circuit board protection racks 12, reducing the damage caused by the impact between the circuit board and the top.

[0039] Both the inner pad and the bottom pad are made of anti-static adhesive. In addition, anti-static film is sprayed on the circuit board protection frame, movable cover and inner surface of the box shell to avoid the adverse effects of static electricity on the circuit board.

[0040] In addition, it should be noted that the circuit board protective frame, movable cover and box shell can all be made of the same plastic material as traditional circuit board turnover boxes, and can be integrally injection molded.

[0041] like Figure 1 and Figure 2 As shown, preferably, when the box shell 1 is integrally injection molded, reinforcing ribs 2 are also formed on the outer wall to enhance the structural strength of the box; box handles 3 are symmetrically arranged at the lower position near the top edge 4 of the box shell 1 to facilitate manual handling of the box.

[0042] Preferably, hoisting holes 8 can be opened at the four vertices of the raised edge 5 to match the hoisting operation of the circuit board protection transfer box.

[0043] In summary, the circuit board protection transfer box disclosed in this embodiment utilizes a flexible antistatic rubber inner pad and an antistatic rubber bottom pad to further enhance the protection of the circuit board, thereby helping to further reduce the occurrence of mechanical damage to the circuit board.

[0044] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
