Description

Technical Field

[0001] This utility model relates to the field of circuit board storage technology, and in particular to a carrier that can accommodate PCBs of different sizes. Background Technology

[0002] A PCB, or Printed Circuit Board, is a core component of electronic devices, used for electrical connections between electronic components and for signal transmission and power distribution via pre-designed conductive lines. During production, it typically needs to be transferred or stored for subsequent assembly. Existing carriers are usually custom-developed based on the PCB size, with a support slot at each end of the PCB's side. However, if the PCB size decreases, only the lower end of the PCB's side is held in place by the lower support slot, leaving the upper end unsupported. This can cause the PCB edge to be suspended, affecting stability. If the PCB is thin, this method of holding only the two ends while leaving the middle unsupported can easily cause the PCB to deform and bend under gravity, resulting in drooping and stacking. This method cannot effectively meet the storage needs of PCBs of different sizes. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one part of the embodiments of the present utility model, and not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] For printed circuit boards (PCBs), during the production process, considering the requirements of the manufacturing process, PCBs need to be transferred or stored. Since directly stacking PCBs can easily cause them to scratch and be damaged, they need to be stored with spacing between them. Existing carriers usually need to be custom-developed according to the PCB size, with a support slot at each end of the PCB side. As a result, if the PCB size decreases, only the lower end of the PCB side will be held by the lower support slot, while the upper end cannot reach the upper support slot. This can easily cause the edge of the PCB to be suspended, affecting stability. If the PCB is thin, holding only the two ends of the side while the middle is suspended can easily cause the PCB to deform and bend under gravity, resulting in drooping and stacking. This cannot effectively meet the storage needs of PCBs of different sizes.

[0038] In view of this, the present invention provides a carrier that can accommodate PCBs of different sizes. By providing a first and a second slot that extend continuously and penetrate both ends of the substrate and side plate respectively, it can be used for PCBs of different sizes. The side and bottom edges of PCBs of different sizes can be positioned in the first and second slots, making the PCBs more stable during storage and preventing them from falling off or deforming.

[0039] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides a carrier 100 capable of accommodating PCBs of different sizes. The PCB has an adjacent first side and a second side. The carrier 100 capable of accommodating PCBs of different sizes includes:

[0041] The support frame 10 includes a first support component 11 and a second support component 12 arranged in a cross manner. The first support component 11 has a first support surface, and the second support component 12 has a second support surface that is perpendicular to the first support surface.

[0042] A substrate 20 is disposed on a first supporting surface. The substrate 20 has a first groove 21 extending continuously along its length and penetrating both end faces. The first groove 21 supports a first side.

[0043] Side plate 30 is provided on the second support surface. The side plate 30 has a second plate groove 31 that extends continuously along the height direction and passes through both end faces. The second plate groove 31 is used to support the second side.

[0044] In this embodiment, the support frame 10 provides a stable support structure for mounting the substrate 20 and side plate 30. The support frame 10 consists of a first support component 11 and a second support component 12 arranged in a cross configuration. This bidirectionally constrains the horizontal and vertical degrees of freedom of the PCB board, reducing the risk of displacement and slippage due to vibration during transit or storage. The substrate 20 supports the first side of the PCB board. The first slot 21 penetrating both ends of the substrate 20 allows the first side of the PCB board to slide and be positioned at any position along its length, adapting to the lateral dimension requirements of different PCB board sizes. Simultaneously, the side plate 30 supports the second side of the PCB board. The second slot 31 penetrating both ends of the side plate 30 allows the second side of the PCB board to be inserted from the top, adapting to the longitudinal dimension requirements of different PCB board sizes. This embodiment of the invention is applicable to PCB boards of different sizes, ensuring that the first and second sides of PCB boards of different sizes can be positioned within the first slot 21 and the second slot 31, thereby making the PCB board more stable during storage and reducing the risk of detachment and deformation.

[0045] Specifically, a carrier 100, capable of loading PCBs of different sizes, is used in a board loading and unloading device. This carrier 100 includes a housing containing a robotic arm and a transport mechanism. At least one set of processing stations is also located within the housing. The carrier 100 can be moved to the processing station by an AGV (Automated Guided Vehicle) vehicle, where the robotic arm can either transfer PCBs transported by the transport mechanism onto the carrier 100, or transfer PCBs from the carrier 100 onto the transport mechanism. The carrier 100, capable of loading PCBs of different sizes, includes a support frame 10, a substrate 20, and side plates 30. The material of the support frame 10 is not limited; it can be made of polymer materials to meet the requirements of high-strength applications, or it can be made of high-strength metal materials, possessing a certain load-bearing capacity and providing support. The substrate 20 is fixed to the first support surface of the support frame 10. A first slot 21 is provided to support the first side of the PCB board. It can be understood that the first side of PCB boards of different sizes can be accommodated within the first slot 21, achieving stable support for PCB boards of different sizes in the length direction. The side plate 30 is fixed to the second support surface of the support frame 10. A second slot 31 is provided to support the second side of the PCB board. It can be understood that the second side of PCB boards of different sizes can be accommodated within the second slot 31, achieving stable support for PCB boards of different sizes in the height direction.

[0046] It should be noted that multiple first board grooves 21 are spaced apart along the width direction of the substrate 20, and each first board groove 21 is provided with a corresponding second board groove 31. The channel width of the first board groove 21 is adapted to the first side of the PCB board, and the channel width of the second board groove 31 is adapted to the second side of the PCB board.

[0047] Furthermore, in one embodiment of this utility model, the length of the first groove 21 ranges from 200mm to 570mm; and / or,

[0048] The length of the second groove 31 ranges from 310mm to 780mm.

[0049] In this embodiment, the technical solution ensures that the lengths of the first slot 21 and the second slot 31 can accommodate PCBs of different sizes. It is understood that an excessively short first slot 21 or second slot 31 may cause the PCB edge to be suspended, increasing the risk of slippage during vibration or transfer. The minimum length of the first slot 21 and the second slot 31 ensures that the carrier 100 can accommodate the first and second sides of smaller PCBs, reducing the likelihood of PCB instability due to excessively short slots. Conversely, the maximum length of the first slot 21 and the second slot 31 reduces material waste caused by excessively long slots, lowering the manufacturing cost of the carrier 100.

[0050] Furthermore, in one embodiment of this utility model, the depth of the first groove 21 ranges from 10mm to 40mm; and / or,

[0051] The depth of the second groove 31 ranges from 10mm to 40mm.

[0052] In this embodiment, the technical solution employs this configuration to ensure that the depths of the first slot 21 and the second slot 31 are sufficient to stabilize PCBs of different sizes. It is understood that an excessively shallow first slot 21 or second slot 31 may cause the PCB edges to be suspended, increasing the risk of deformation due to external forces. The minimum depth of the first slot 21 and the second slot 31 ensures that the carrier 100 provides sufficient contact area, guaranteeing stability during storage and ensuring effective fixation of the PCB after it is embedded in the slot, reducing positioning offset due to insufficient depth. Conversely, the maximum depth of the first slot 21 and the second slot 31 reduces the risk of the PCB being over-embedded in the slot, which could affect subsequent handling operations or interference with other components.

[0053] Furthermore, refer to Figure 1 , Figure 3 In one embodiment of the present invention, the first plate groove 21 has a groove bottom and a first side wall 211 and a second side wall 212 connected to the groove bottom. The first side wall 211 is vertically arranged, the second side wall 212 is inclined, and the distance between the first side wall 211 and the second side wall 212 gradually increases in the direction away from the groove bottom.

[0054] In this embodiment, the second sidewall 212 of the first slot 21 is inclined to form a wedge-shaped inlet, which facilitates automatic position correction during PCB board insertion and reduces friction or edge wear caused by angular deviation. The gradually increasing spacing allows the PCB board to gradually conform to the bottom of the slot during insertion, reducing stress concentration caused by sudden force. Of course, to optimize the smoothness of the insertion process, the opening of the second slot 31 is flared, so that the second side of the PCB board can be easily inserted from the port of the second slot 31.

[0055] Furthermore, refer to Figure 1 In one embodiment of this utility model, the carrier 100, which can accommodate PCBs of different sizes, further includes a clamping structure 40, which is disposed on the first support surface and used to clamp the first side; and / or,

[0056] The clamping structure 40 is provided on the second support surface and is used to clamp the second side.

[0057] In this embodiment, the carrier 100 may further include a clamping structure 40 to provide additional stability. The clamping structure 40 may be a fixing plate with multiple grippers. The fixing plate may be disposed on a first support surface to clamp a first edge of the PCB board. Alternatively, it may be disposed on a second support surface to clamp a second edge of the PCB board. The first and second support surfaces may also be disposed simultaneously. It is understood that when the fixing plate is disposed on the first support surface, each first slot 21 corresponds to one gripper; when the fixing plate is disposed on the second support surface, each second slot 31 corresponds to one gripper.

[0058] Furthermore, refer to Figure 1 In one embodiment of the present invention, the side plate 30 includes a first sub-plate and a second sub-plate that are spaced apart from each other, with an avoidance groove between the first sub-plate and the second sub-plate, and the clamping structure 40 is embedded in the avoidance groove.

[0059] In the technical solution adopted in this embodiment, the side plate 30 may also include a first sub-board and a second sub-board. In this embodiment, the set avoidance slot can provide an embedding space for the clamping structure 40, thereby facilitating the clamping of the PCB board. The first sub-board and the second sub-board set on opposite sides of the clamping structure 40 can constrain and ensure that the PCB board will not slide or shift due to vibration or handling during storage, thus maintaining positioning accuracy.

[0060] Furthermore, refer to Figure 4 In one embodiment of the present invention, the first support component 11 includes a base frame 111, a bracket 112 connected to the base frame 111, and a first mounting bracket 113 connected to the bracket 112. The end of the first mounting bracket 113 away from the bracket 112 is connected to the base frame 111, and the side of the first mounting bracket 113 away from the base frame 111 forms a first support surface that is inclined.

[0061] The second support component 12 includes a side frame 121 located at one end of the base frame 111 away from the bracket 112, a pad 122 connected to the side frame 121, and a second mounting bracket 123 connected to the pad 122. The surface of the second mounting bracket 123 facing away from the side frame 121 forms a second support surface.

[0062] In this embodiment, the first support component 11 may include a base frame 111, a bracket 112, and a first mounting bracket 113. The second support component 12 may include a side frame 121, a pad 122, and a second mounting bracket 123. In this embodiment, the base frame 111, the bracket 112, and the first mounting bracket 113 form a triangular closed frame, which can provide additional stability and reduce the risk of stress concentration at a single support point. Simultaneously, the first mounting bracket 113 forms an inclined first support surface, which can counteract the lateral displacement of the PCB board, making the PCB board more stable during storage. The side frame 121 adjusts the angle difference between the second side of the PCB board and the height direction through the pad 122, ensuring that the second support surface is evenly stressed. Regarding the connection method of the first support component 11 and the second support component 12, the base frame 111, the bracket 112, and the first mounting bracket 113 can be welded together, and the side frame 121, the pad 122, and the second mounting bracket 123 can also be welded together. It should be noted that the included angle between the first support surface and the second support surface is 90 degrees.

[0063] Furthermore, refer to Figure 1 In one embodiment of the present invention, the carrier 100, which can accommodate PCB boards of different sizes, further includes a first sheet metal part 50. The first sheet metal part 50 has a first plane, which is connected to the end face of the substrate 20 and the side face of the first mounting frame 113 respectively, so that the end face of the substrate 20 and the side face of the first mounting frame 113 are coplanar.

[0064] The carrier 100, which can accommodate PCBs of different sizes, also includes a second sheet metal part 60. The second sheet metal part 60 has a second plane, which is connected to the end face of the side plate 30 and the side of the second mounting bracket 123, respectively, so that the end face of the side plate 30 and the side of the second mounting bracket 123 are coplanar.

[0065] In this embodiment, the first sheet metal part 50 and the second sheet metal part 60 ensure that the end face of the substrate 20 is coplanar with the side face of the first mounting bracket 113, and that the end face of the side plate 30 is coplanar with the side face of the second mounting bracket 123. This allows for quick positioning and mounting of the substrate 20 and the side plate 30, reducing the risk of tilting. Furthermore, the coplanar design enables rapid alignment of the PCB board with the substrate 20 and the side plate 30.

[0066] Furthermore, refer to Figure 1 , Figure 4 In one embodiment of the present invention, the carrier 100, which can accommodate PCB boards of different sizes, further includes a first fixing component. The first fixing component includes a first fixing part 70 and a first mating part 71 respectively disposed on the substrate 20 and the first mounting frame 113. The first fixing part 70 is used to cooperate with the first mating part 71 to fix the substrate 20 when the end face of the substrate 20 and the side face of the first mounting frame 113 are coplanar.

[0067] The carrier 100, which can accommodate PCBs of different sizes, also includes a second fixing component. The second fixing component includes a second fixing part 80 and a second mating part 81 respectively disposed on the side plate 30 and the second mounting bracket 123. The second fixing part 80 is used to cooperate with the second mating part 81 to fix the side plate 30 and the side of the second mounting bracket 123 when the end face of the side plate 30 and the side face of the second mounting bracket 123 are coplanar.

[0068] In this embodiment, the substrate 20 and the side plate 30 can be fixed by the first fixing component and the second fixing component. In this embodiment, the first fixing component may include a first fixing part 70 and a second mating part 81. Both the first fixing part 70 and the first mating part 71 can be threaded holes. The first fixing part 70 and the first mating part 71 are automatically aligned when the end face of the substrate 20 is coplanar with the side face of the first mounting bracket 113, and the substrate 20 is fixed by the engagement of bolts and threaded holes. The second fixing component may include a second fixing part 80 and a second mating part 81. The second fixing part 80 and the second mating part 81 can also be threaded holes. The second fixing part 80 and the second mating part 81 are automatically aligned when the end face of the side wall is coplanar with the side face of the first mounting bracket 113, and the side plate 30 is fixed by bolts and threaded holes.

[0069] Furthermore, refer to Figure 4 In one embodiment of this utility model, at least two first mating portions 71 are provided at intervals along the length direction of the first mounting bracket 113; and / or,

[0070] At least two second mating parts 81 are provided at intervals along the height direction of the second mounting bracket 123.

[0071] In this embodiment, the clamping structure 40 is configured such that when it is positioned on the first support surface, the first mating portions 71 on both sides of the clamping structure 40 can mount two identical substrates 20; and when it is positioned on the second support surface, the second mating portions 81 on both sides of the clamping structure 40 can mount two identical side plates 30. This effectively meets the storage requirements for PCBs of different sizes.
