Description

Technical Field

[0001] The utility model relates to the field of PCB production, in particular to a PCB board storage device. Background Art

[0002] The electronics manufacturing industry often involves the manufacture, testing, and assembly of PCBs (flexible printed circuit boards). During the actual unified assembly process, a large number of PCBs are used. Because PCBs are inherently fragile, moving them poses certain risks and is difficult to place. In practice, they are manually moved and sorted, which wastes manpower and poses safety risks, leading to decreased production efficiency and increased labor costs.

[0003] In the prior art, PCB boards are stored and transported using transport vehicles with optimized structures. For example, Chinese utility model patent application number CN201220385371.2 discloses a transport vehicle capable of placing PCB boards on both sides. The transport vehicle utilizes an L-shaped plate to store and place PCB boards. Once a certain number of PCB boards are stored, the transport vehicle utilizes a wheel structure to transport the PCB boards. However, in use, it has been found that the L-shaped plate has a simple structure, resulting in a poor storage capacity. Furthermore, the intended processing surface of the PCB board is the placement surface, which easily scratches the contact surface and reduces the yield of the PCB boards. Therefore, a more rationally structured storage and transportation device is needed to store PCB boards and address the above-mentioned deficiencies in the prior art. Utility Model Content

[0004] The present invention provides a solution to the technical problems that the PCB board transportation device in the prior art has a poor storage capacity and is prone to affecting the panel during storage.

[0005] To achieve the above objectives, the present invention provides a transport vehicle that supports the rapid guidance and storage of PCB boards, comprising a base plate, one side of the base plate being provided with a plurality of sliding wheels, and four edges of the other side being provided with protruding profile columns, wherein a plurality of groups of the profile columns are arranged around a frame having a storage space; a first profile plate and a second profile plate are provided within the storage space, a first profile plate having a surface fixedly connected to a side of the second profile plate and being obliquely disposed within the frame;

[0006] The surface of the first profile plate is provided with a plurality of first grooves for clamping the PCB board, and the surface of the second profile plate is also provided with a plurality of second grooves corresponding to the first grooves for guiding the PCB board to move into the first grooves.

[0007] As an improved solution of the present application, the second trough body and the first trough body together form a fixing structure for clamping the single PCB board.

[0008] As an improved solution of the present application, a plurality of ball structures are arranged at intervals on the bottom of any second groove body.

[0009] As an improved solution of the present application, the two opposite side walls of any second trough body are provided with a first flexible ridge and a second flexible ridge, and the first flexible ridge and the second flexible ridge extend to the two ends of the corresponding second trough body; when placing the PCB board, the first flexible ridge and the second flexible ridge are adhered to the two sides of the PCB board, so that the PCB board is located on the transport line formed by multiple groups of the ball structures.

[0010] As an improved solution of the present application, the first flexible convex strip and the second flexible convex strip are both made of silicone, and the facing sides are coated with a smooth layer.

[0011] As an improved solution of the present application, the first flexible ridge and the second flexible ridge are airbags, and a smooth layer is formed on the surface of the airbag.

[0012] As an improved solution of the present application, the relative inner walls of any of the first trough bodies are inclined surfaces, and an elastic layer is formed on the inclined surfaces.

[0013] As an improved solution of the present application, the elastic layer is a silicone layer.

The third profile plate and the fourth profile plate are fixed in the frame in accordance with the structure of the first profile plate and the second profile plate.

[0016] The beneficial effects of the present invention are as follows: compared with the prior art, the present invention provides a transport vehicle that supports rapid guided storage of PCB boards. When in use, the PCB boards are guided and moved into the first trough by the second trough, and then engaged with the PCB boards by the first trough. The above storage action is repeated, thereby realizing vertical storage of multiple groups of PCB boards. The gaps between the stored PCB boards are reduced, thereby reducing the wear and tear on the patterns on the board surfaces. Moreover, due to the changed storage posture during storage, a larger number of PCB boards can be stored.

[0025] In order to more clearly illustrate the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0026] In the following description, examples are provided to provide a deeper understanding of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. It should be understood that the specific embodiments described are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0027] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0028] In the prior art, PCB boards are stored and transported using transport vehicles with optimized structures. For example, Chinese utility model patent application number CN201220385371.2 discloses a transport vehicle capable of placing PCB boards on both sides. The transport vehicle utilizes an L-shaped plate to store and place PCB boards. Once a certain number of PCB boards are stored, the transport vehicle utilizes a wheel structure to transport the PCB boards. However, in use, it has been found that the L-shaped plate has a simple structure, resulting in a poor storage capacity. Furthermore, the intended processing surface of the PCB board is the placement surface, which easily scratches the contact surface and reduces the yield of the PCB boards. Therefore, a more rationally structured storage and transportation device is needed to store PCB boards and address the above-mentioned deficiencies in the prior art.

[0029] In order to solve the above technical problems, this application provides a transport vehicle that supports rapid guidance and storage of PCB boards. Figure 1 To the attached Figure 4 , including a seat plate, one side of the seat plate is provided with multiple sliding wheels (not shown in the figure), and the four edges of the other side are provided with protruding profile columns, and multiple groups of profile columns are arranged around a frame 1 with a storage space; a first profile plate 2 and a second profile plate 3 are provided in the storage space, one side of the first profile plate 2 is fixedly connected to one side of the second profile plate 3, and is tilted in the frame 1, so that the user can take and place the PCB board; further, the surface of the first profile plate 2 is provided with multiple groups of first grooves 21 for clamping the PCB board, and the surface of the second profile plate 3 is also provided with multiple groups of second grooves corresponding to the first grooves 31, which are used to guide the PCB board to move into the first groove.

[0030] During use, technicians guide the PCB board into the first trough 21 through the second trough 31, and then engage the edge of the PCB board with the first trough 21, and repeat the above storage action, that is, multiple groups of PCB boards can be stored upright. The gaps between the stored PCB boards will reduce the wear and tear on the patterns on the board surface, and because the storage posture is changed during storage, more PCB boards can be stored. Repeating the above storage action allows the second trough 31 to be equipped with the corresponding PCB boards in turn, and then the PCB boards are moved by the wheel set. This has both the characteristics of storage and easy movement, and has a better promotion prospect.

[0031] It can be seen that compared with the traditional storage and transportation vehicle that stacks PCBs through L-boards, the present application has a first trough 21 and a second trough 31 correspondingly arranged on the first profile plate 2 and the second profile plate 3, and utilizes multiple groups of first troughs 21 to achieve the spaced upright storage of multiple groups of PCB boards, and the second trough 31 is used to achieve the rapid placement of PCB boards. The above design not only increases the storage capacity of PCB boards, but also better protects the PCB boards from mutual wear; after the storage is completed, it can be moved by the wheel group, which is more convenient to use.

[0032] In this embodiment, the second groove body 31 and the first groove body 21 jointly form a fixed structure for clamping a single PCB board; it is not difficult to understand that when the expected position is reached, the groove structure based on the first groove body 21 and the second groove body 31 is used to clamp two adjacent side edges of the same PCB board, so that the PCB board is more stable in the enclosed area formed by the first bottom plate and the second bottom plate.

[0033] In order to enable technicians to transport PCBs more smoothly through the second trough 31, in this embodiment, multiple ball structures 32 are arranged at intervals at the bottom of any second trough 31. It is not difficult to understand that first, a ball groove is reserved on the bottom surface of the second trough 31, and then the balls are placed into it to obtain the ball structure 32; when in use, the technician holds the PCB board and places one side of the PCB board against the multiple ball structures 32. The low damping provided by the multiple groups of ball structures 32 allows the PCB board to slide quickly in the second trough 31, and then quickly reaches the first trough 21 to be clamped and fixed.

[0034] In another improvement scheme, the PCB board is prone to tilting during the sliding process, causing the PCB board to collide with the inner wall of the second trough body 31. In order to prevent the PCB board from being damaged and make transportation smoother, in this embodiment, the two opposite side walls of any second trough body 31 are provided with a first flexible ridge 33 and a second flexible ridge 34, and the first flexible ridge 33 and the second flexible ridge 34 extend to the two ends of the corresponding second trough body 31; when placing the PCB board, the first flexible ridge 33 and the second flexible ridge 34 are attached to the two sides of the PCB board so that the PCB board is located on the transportation line formed by multiple groups of ball structures 32; it is not difficult to understand that the first flexible ridge 33 and the second flexible ridge 34 form a buffer to protect the board surface when it is tilted during transportation, and at the same time, the PCB board can move more stably on the transportation line, and then the PCB board can be quickly transported to the first trough body 21 for assembly and storage.

[0035] In a specific solution, the first flexible ridge 33 and the second flexible ridge 34 are both made of silicone, and the facing sides are coated with a smooth layer. Silicone has a large damping, and directly using silicone material may cause the surface of the PCB board to touch the silicone material, which may cause jamming. Therefore, a special smooth layer is required to reduce the damping of the PCB board; in another solution, the first flexible ridge 33 and the second flexible ridge 34 are airbags, and a smooth layer is formed on the surface of the airbag, which can also achieve the above-mentioned buffering, positioning and no impact on sliding.

[0036] In this embodiment, the relative inner walls of any first groove body 21 are all inclined surfaces, and an elastic layer is formed on the inclined surface. It is not difficult to understand that the PCB board is clamped by the inclined surface. In the clamped state, the PCB board is not easy to loosen. At the same time, the PCB board is buffered by the elastic layer to prevent collision. In the specific solution, the elastic layer is a silicone layer.

[0037] In this embodiment, a third profile plate 4 having the same structure as the first profile plate 2 and a fourth profile plate 5 having the same structure as the second profile plate 3 are also included. The third profile plate 4 and the fourth profile plate 5 are fixed in the frame 1 in accordance with the structure of the first profile plate 2 and the second profile plate 3. By correspondingly arranging the fourth bottom plate and the third bottom plate, the effect of double-layer placement and storage of PCB boards is achieved.

[0038] The advantages of this utility model are:

[0039] 1. By correspondingly providing the first and second troughs on the first and second profile plates, multiple sets of first troughs can be used to store multiple sets of PCBs in an upright manner, and the second troughs can be used to quickly place the PCBs. This design not only increases the storage capacity of PCBs but also better protects the PCBs from mutual wear. Once the storage handle is completed, it can be moved by the wheels, making it more convenient to use.

[0040] 2. The first flexible ridges and the second flexible ridges form a buffer to protect the board when it is tilted during transportation, and at the same time, the PCB board can move more stably on the transportation line, and then the PCB board can be quickly transported to the first trough for assembly and storage.

[0041] The above disclosures are only a few specific embodiments of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
