Description

Technical Field

[0001] This utility model specifically relates to a flexible circuit board storage device. Background Technology

[0002] Flexible printed circuit boards (FPCs) are widely used in precision devices such as smartphones, smart wearables, and automotive electronics due to their thinness, flexibility, and high wiring density. In the production, warehousing, transportation, and automated assembly of FPCs, specialized pallets are required to ensure stable support and precise feeding, thus preventing structural damage or positioning deviations.

[0003] Because FPC surfaces typically have exposed copper foil lines, pads, and precision components (such as chips and connectors), and the substrate (such as PI film) is fragile, to prevent scratches, component detachment, or electrostatic damage caused by interlayer friction, the industry generally requires that multiple FPCs be stacked and stored with interlayer spacing between them—that is, each FPC is placed in a separate tray, and then the trays are stacked layer by layer to form an "FPC-tray-FPC-tray" spacing structure.

[0004] While this spacing method reduces direct contact damage, existing pallet designs still have significant flaws. Traditional spaced pallets are mostly integrated fixed structures with fixed dimensions such as length and width of the load-bearing area, only suitable for specific FPC sizes. When production needs change (such as FPC size changes), the entire batch of pallets must be replaced with the corresponding size, resulting in poor equipment versatility, high changeover costs, and idle pallets occupying a large amount of storage space, increasing enterprise operating costs. Some improved pallets can adapt to FPCs of different widths by adjusting the spacing of the side baffles, but the support structure design is unreasonable: the FPC is only supported by the side baffles at the edges, leaving the central area completely unsupported. This "side support, no central support" structure leads to: FPC deformation and damage: FPCs themselves are thin and lightweight (the substrate thickness is usually only 0.025-0.2mm), and when the central area is unsupported, it is prone to permanent bending due to gravity, causing circuit breakage and pad detachment. Utility Model Content

[0005] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a flexible circuit board storage device.

[0006] A flexible circuit board storage device includes an anti-static tray body. The anti-static tray body includes two fixed plates arranged longitudinally at intervals and two carrier plates arranged laterally at intervals. A plurality of support rods are arranged laterally between the two fixed plates, and the support rods are movable up and down relative to the fixed plates. An elastic element abuts against the support rods and the fixed plates, allowing the support rods to maintain an upward tendency. The carrier plates are movably disposed between the two fixed plates. Each of the two carrier plates has a recessed cavity on its inner side, into which the support rods can be housed. When the support rods are disengaged from the cavity, the elastic element keeps their upper ends flush with the upper surface of the carrier plate. The carrier plates have a plurality of screw holes spaced laterally, and one side of each fixed plate has a through hole corresponding to the screw holes, into which a connecting screw capable of threaded engagement with the screw hole is inserted.

[0007] In one embodiment, guide ramps are provided on the opposite inner sides of the two carrier plates. The guide ramps can press against the support rods in sequence as the carrier plates move, causing the support rods to move downwards and compress the elastic force of the elastic element.

[0008] In one embodiment, the support rod includes two spaced sliders and a connecting roller rotatably disposed between the two sliders. The fixed plate is provided with a plurality of vertical guide grooves through it at horizontal intervals, and the two sliders are respectively movably disposed in the corresponding vertical guide grooves of different fixed plates.

[0009] In one embodiment, the fixing plate is rotatably provided with a locking member on the side opposite to the support rod. The locking member has a plurality of locking blocks spaced laterally relative to the side that is in close contact with the fixing plate. The slider has a recessed groove on one side. When the support rod is disengaged from the recess and located at the upper end of the vertical guide groove, the locking blocks can flip and lock into the corresponding groove of the slider. When the support rod is located in the recess, the locking blocks are located in the vertical guide groove and above the corresponding slider. The locking member has a through hole at the corresponding through hole position.

[0010] In one embodiment, the locking member is attached to one side of the fixing plate by a magnet, or the locking member is fastened to one side of the fixing plate by bolts.

[0011] In one embodiment, the carrier plate has recessed guide grooves on both sides, and guide rails are protruding laterally at intervals on the opposite inner sides of the two fixed plates, with the guide rails movably fitted within the guide grooves.

[0012] In one embodiment, the antistatic tray body is of several types, and the several antistatic tray bodies can be stacked vertically.

[0013] In one embodiment, limiting flanges are provided on the opposite outer sides of the two carrier plates, and a positioning block is provided at the upper end of the limiting flange. The lower side of the carrier plate has a positioning groove that can cooperate with the positioning block.

[0014] In summary, the advantages of this utility model over the prior art are:

[0015] This invention utilizes a laterally adjustable carrier plate and a flexible, upward-supporting rod structure to flexibly adapt to FPCs of different sizes. This eliminates the need to replace entire batches of pallets due to changes in FPC specifications, significantly reducing equipment downtime and storage costs, and improving the versatility of production equipment. Furthermore, the flexible, upward-supporting rod, in conjunction with the carrier plate, forms a complete support surface, overcoming the shortcomings of traditional pallets that are "supported on both sides and suspended in the middle." When placing the FPC, not only are the edges supported by the carrier plate, but the middle also receives stable support through the support rod, preventing permanent bending, circuit breakage, or pad detachment due to gravity.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 4The present invention preferably provides a flexible circuit board storage device, including an anti-static tray body. The anti-static tray body includes two fixed plates 1 arranged longitudinally at intervals and two carrier plates 2 arranged laterally at intervals. A plurality of support rods 3 are arranged laterally between the two fixed plates 1, and the support rods 3 can move up and down relative to the fixed plates 1. An elastic element 4 abuts against the support rods 3 and the fixed plates 1, and the elastic element 4 keeps the support rods 3 in an upward trend. The carrier plates 2 are movably disposed between the two fixed plates 1. A cavity 5 is recessed on the inner side of each of the two carrier plates 2, and the plurality of support rods 3 can be housed in the cavity 5. When the support rods 3 are disengaged from the cavity 5, the elastic element 4 keeps their upper ends flush with the upper side of the carrier plate 2. The carrier plates 2 are provided with a plurality of screw holes 6 at intervals laterally. A through hole 7 is provided on one side of the fixed plate 1 corresponding to the screw holes 6, and a connecting screw (not shown in the figure) that can be threaded into the through hole 7 is inserted into the through hole 7.

[0023] Specifically, the fixing plate, carrier plate, and support rod are all made of anti-static materials. By adjusting the position of the carrier plate on the fixing plate, the carrier plate is fixed in the appropriate position using connecting screws to accommodate FPCs of different widths. When an FPC needs to be placed, if the FPC is large, the support rod disengages from the cavity and moves upward under the elastic force of the elastic element, making its upper end flush with the upper side of the carrier plate, forming a support surface to support the FPC. If the FPC is small, the support rod can be stored in the cavity, and the FPC is supported only by the carrier plate. Furthermore, through the carrier plate, which can be adjusted laterally, and the elastically upward-lifting support rod structure, different sizes of FPCs can be flexibly adapted, eliminating the need to replace the entire batch of pallets due to changes in FPC specifications, significantly reducing equipment idleness and storage costs, and improving the versatility of production equipment. Moreover, the elastically upward-lifting support rod, together with the carrier plate, forms a complete support surface, changing the defect of traditional pallets that are "supported on both sides and suspended in the middle". When the FPC is placed, not only are the edges supported by the carrier board, but the middle part can also be stably supported by the support rod to prevent permanent bending, circuit breakage or pad detachment caused by gravity sagging.

[0024] Furthermore, guide ramps 8 are respectively provided on the inner sides of the two carrier plates 2. The guide ramps 8 can move with the carrier plates 2 and successively press against the support rods 3, causing the support rods 3 to move downward and compress the elastic element 4. Specifically, when the position of the carrier plates is adjusted, the guide ramps move with the carrier plates. If the carrier plates move inward, the guide ramps will successively press against the support rods, forcing the support rods to move downward and compress the elastic element. Through the guiding effect of the guide ramps, the support rods can be smoothly pressed into the concave cavity, avoiding damage caused by the carrier plates directly impacting the support rods, and at the same time realizing the automatic storage of the support rods.

[0025] Furthermore, the support rod 3 includes two spaced-apart sliders 9 and a connecting roller 10 rotatably disposed between the two sliders 9. The fixed plate 1 has several vertical guide grooves 11 spaced horizontally through it, and the two sliders 9 are respectively movably disposed within the corresponding vertical guide grooves 11 of different fixed plates 1. Specifically, the sliders slide up and down within the vertical guide grooves, providing guidance for the up and down movement of the support rod and ensuring the stability of the support rod's movement. The connecting roller is rotatably disposed between the two sliders. When the FPC is placed or removed, the connecting roller can rotate with the movement of the FPC, converting the sliding friction between the FPC and the support rod into rolling friction, reducing wear on the FPC surface.

[0026] Furthermore, the fixing plate 1 is rotatably provided with a locking member 12 on the side opposite to the support rod 3. The locking member 12 is provided with several locking blocks 13 at horizontal intervals on the side that is in close contact with the fixing plate 1. The slider 9 has a recessed groove 14 on one side. When the support rod 3 is disengaged from the cavity 5 and located at the upper end of the vertical guide groove 11, the locking block 13 can flip and lock into the groove 14 corresponding to the slider 9 with the locking member 12. When the support rod 3 is located in the cavity 5, the locking block 13 is located in the vertical guide groove 11 and above the corresponding slider 9. The locking member 12 has a through hole at the position corresponding to the through hole 7.

[0027] Specifically, when the support rod is disengaged from the recess and positioned at the upper end of the vertical guide groove, the locking component is flipped to engage the locking block within the corresponding slider's slot, thus locking the support rod in that position and preventing it from moving downwards under stress during FPC support, ensuring the stability of the support. When the support rod is inside the recess, the locking block is located within the vertical guide groove and above the corresponding slider, without affecting the storage of the support rod. The through hole on the locking component facilitates the passage of connecting screws without interfering with the fixation of the carrier plate and the fixing plate.

[0028] Furthermore, the locking member 12 is attached to one side of the fixing plate 1 by a magnet, or the locking member 12 is fastened to one side of the fixing plate 1 by bolts. Specifically, when using magnetic adsorption, the locking member can be quickly attached to and separated from the fixing plate, making operation convenient; when using bolt fastening, the connection between the locking member and the fixing plate is more secure, ensuring the stability of the locking effect. Operators can choose the appropriate fixing method according to actual needs.

[0029] Furthermore, the carrier plate 2 has recessed guide grooves 15 on both sides, and guide rails 16 are laterally spaced and protruding from the inner sides of the two fixed plates 1. The guide rails 16 are movably fitted within the guide grooves 15. Specifically, the cooperation between the guide rails and guide grooves provides guidance for the lateral movement of the carrier plate on the fixed plates, ensuring the stability and accuracy of the carrier plate adjustment process, preventing the carrier plate from shifting, ensuring the fitting accuracy between the carrier plate and the support rod, and thus ensuring stable support for the FPC.

[0030] Furthermore, the anti-static tray body is comprised of several units, and these anti-static tray bodies can be stacked vertically. Specifically, when multiple trays are stacked, the bottom of the upper tray fits against the top of the lower tray, achieving layered storage of the FPC. This stacking method saves storage space and facilitates batch management and transportation of FPCs, meeting the needs of large-scale production.

[0031] Furthermore, limiting flanges 17 are respectively provided on the opposite outer sides of the two carrier plates 2. A positioning block 18 is provided at the upper end of each limiting flange 17, and a positioning groove 19 is recessed on the lower side of each carrier plate 2 to cooperate with the positioning block 18. Specifically, when multiple pallets are stacked, the positioning groove on the lower side of the upper pallet carrier plate cooperates with the positioning block at the upper end of the limiting flange of the lower pallet to achieve precise positioning between the pallets, preventing lateral displacement or shaking of the pallets during stacking, ensuring the stability and safety of the stack, and avoiding damage to the FPC due to collisions or compression during stacking.
