Description

Technical Field

[0001] The present invention relates to the technical field of circuit boards, and in particular to a transportation protection device for vehicle circuit boards. Background Art

[0002] PCBs, also known as printed circuit boards, provide electrical connections for electronic components. PCB manufacturing involves assembling a variety of smaller, more expensive electronic components, resulting in high costs and the risk of damage. During PCB production and processing, they need to be transported, but existing PCB transport equipment struggles to effectively protect them.

[0003] Existing Chinese patent: A transportation protection device for PCB circuit boards (CN118850550B); this device uses a transmission assembly to drive a rotating plate to rotate, so that the rotating plate and the sealing frame form a closed space. The transmission assembly then rotates and drives the plug plate downward, creating a negative pressure in the pressure box. The air inside the rotating plate and dust on the conductive path on the front of the PCB circuit board are sucked into the dust collection mesh plate, preventing the box from shaking during transportation, which may cause dust particles to adhere to or scratch the conductive path.

[0004] However, each sealed space of the device can only achieve sealing protection for one circuit board, and the rotating plate and sealing frame that form the enclosed space are large in size and occupy more space in the box, resulting in a significant reduction in the space utilization of the box. The practicality of the device is low and needs to be improved. Summary of the Invention

[0005] In order to overcome the disadvantages of the problems mentioned in the background, the present invention provides a transportation protection device for vehicle circuit boards.

[0006] The technical solution is: a transportation protection device for automotive circuit boards, including a box body and a box cover; the box body is detachably connected to the box cover; it also includes a limiting plate, a limiting plate, a connecting plate, a connecting port, a wavy airbag and a connecting plate; the box body is fixedly connected to the limiting plate; the box body is fixedly connected to the limiting plate; the box body is fixedly connected to a plurality of symmetrically distributed connecting plates, and the limiting plate, the limiting plate and the connecting plate together form a rectangular frame; a wavy airbag is placed in the box body; the end of the wavy airbag is connected to a plurality of connecting ports, and the connecting ports cooperate with the limiting plate and the connecting plate; the box body is provided with a plurality of connecting plates, the connecting plates correspond to the connecting ports one by one, and the connecting plates and the connecting ports are snap-connected and connected to each other.

[0007] Furthermore, the wave-shaped airbag has elastic deformation capability.

[0008] Furthermore, the gas injected into the wavy airbag is cold air; and each connecting plate is provided with a connecting port.

[0009] Furthermore, the thickness of the wavy airbag at the corners is smaller than that in other areas.

[0010] Furthermore, the box body, the limiting plate, the limiting plate and the connecting plate together form a "mouth"-shaped cooling cavity; one of the connecting ports is connected to the cooling cavity.

[0011] Furthermore, the box body, the limiting plate, the limiting plate and the connecting plate are all arranged with rounded corners.

[0012] Furthermore, a gas relief valve is provided on the side wall of the box body, and the gas relief valve is communicated with the cooling cavity.

[0013] Furthermore, it also includes dust collection plate 1 and dust collection plate 2; dust collection plate 1 is provided on one side of the wavy airbag; dust collection plate 2 is provided on the other side of the wavy airbag; dust collection plate 1 and dust collection plate 2 both have elastic deformation capabilities; dust collection plate 1 and dust collection plate 2 each have a number of dust collection holes; each connecting plate has a connecting port 2 and a connecting port 3.

[0014] Furthermore, it also includes rectangular air bags; the box body, the limiting plate and the connecting plate are jointly provided with a plurality of symmetrically distributed rectangular air bags.

[0015] The beneficial effects of the present invention are: 1. The present invention forms a wrapping clamp for the plate by expanding the wave-shaped airbag. In this way, during the storage and transportation of the plate, a wave-shaped airbag simultaneously forms a wrapping protection for multiple plates, which can not only prevent external dust particles from entering the box and adhering to the surface of the plate, but also reduce the damage to the plate caused by the shaking of the box during storage and transportation. Compared with the existing technology, while achieving the same protection effect, it significantly increases the number of plates that can be stored in the box and increases space utilization.

[0016] 2. In the present invention, in the process of taking the plate out of the box, after the wavy airbag shrinks and is taken out, the wavy airbag is stretched through the connecting port, so that the two connecting ports move away from each other, so that the wavy airbag is transformed from a wavy state to a flat state. At this time, multiple plates can be taken out at one time without having to take them out one by one, which significantly improves work efficiency.

[0017] 3. The present invention uses the cold air circulating in the wavy airbag to perform wrap-type cooling and heat dissipation on the plate, and uses the cold air circulating in the cooling cavity to perform surround cooling on the outside of the wavy airbag and the inner wall of the box, thereby achieving good cooling and heat dissipation effects and preventing the plate in the box from being damaged due to excessive heat.

[0018] 4. In the present invention, since the thickness of the wavy airbag at the folded corner is smaller than that of other areas, after the wavy airbag is expanded as a whole, the air that continues to be injected into the wavy airbag will cause the wavy airbag folded corners to expand toward each other and contact, thereby wrapping the side edges of the plate. In this way, the plate can be further wrapped, and the side edges of the plate can also be cooled, further improving the cooling and heat dissipation effects of the plate.

[0019] 5. The present invention uses the dust collecting plate 1 and the dust collecting plate 2 to suck the dust particles on the surface of the plate and in the holes and grooves of the plate, so that the dust particles enter the dust collecting plate 1 and the dust collecting plate 2, and then are sucked out through the connecting port 2 and the connecting port 3 on both sides, thereby removing the dust particles attached to the surface of the plate and in the holes and grooves, and avoiding the situation in which the dust particles attached to the surface of the plate scratch the conductive path due to the shaking of the box during the storage and transportation of the plate.

DETAILED DESCRIPTION

[0028] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0029] Example 1

[0030] A transport protection device for automotive circuit boards, such as Figure 1-Figure 7 As shown, it includes a box body 1 and a box cover 2; the box body 1 is detachably connected to the box cover 2;

[0031] It also includes a limiting plate 3, a limiting plate 4, a connecting plate 5, a connecting port 6, a wavy airbag 7 and a connecting plate 8; the box body 1 is bolted to the limiting plate 3; the box body 1 is bolted to the limiting plate 4; the box body 1 is bolted to at least two symmetrically distributed connecting plates 5, and the limiting plate 3, the limiting plate 4 and the connecting plate 5 together form a rectangular frame; a wavy airbag 7 is placed in the box body 1; the end of the wavy airbag 7 is connected to at least two connecting ports 6, and the connecting port 6 cooperates with the limiting plate 3 and the connecting plate 5; the box body 1 is provided with at least two connecting plates 8, the connecting plates 8 correspond to the connecting ports 6 one by one, and the connecting plates 8 and the connecting ports 6 are snap-connected and connected to each other.

[0032] Preferably, the wavy airbag 7 has elastic deformation capability, so that the wavy airbag 7 can be flattened, thereby facilitating the taking and placing of the plate 001.

[0033] The specific work of the present invention is as follows:

[0034] First, it is explained that before the plate 001 is stored, the corrugated airbag 7 is in a contracted state;

[0035] Next, open the box cover 2, take out the corrugated airbag 7 from the box body 1, and then place the plate 001 in a specific manner (such as Figure 4 As shown) is placed in the interlayer of the wavy airbag 7, and then the wavy airbag 7 with the plate 001 is placed in a specific manner (as shown) Figure 3 As shown in the figure, the wavy airbag 7 is placed in the box 1, and the limiting plate 3, the limiting plate 4, and the connecting plate 5 are used to limit the position of the wavy airbag 7. Then, the connecting port 6 is clamped onto the connecting plate 8 on the corresponding side, and the connecting port 6 and the connecting plate 8 are connected to facilitate the subsequent air supply to the wavy airbag 7.

[0036] Then, close the box cover 2, and control the external air pump to inject air into the wavy airbag 7 through the connecting plate 8 and the connecting port 6 in turn, so that the wavy airbag 7 expands, thereby forming a wrapping clamp for the plate 001; in this way, a wavy airbag 7 can be used to wrap and protect multiple plates 001 at the same time; during the storage and transportation of the plates 001, the wavy airbag 7 can effectively prevent external dust particles from entering the box body 1 and adhering to the surface of the plates 001, and at the same time can also reduce the damage to the plates 001 caused by the shaking of the box body 1 during the storage and transportation; compared with the prior art, the present invention significantly improves the storage quantity of the plates 001 in the box body 1 while achieving the same protection effect, thereby increasing the space utilization rate.

[0037] When the sheet 001 needs to be taken out later, first control the contraction of the corrugated airbag 7 so that it is no longer restricted by the limiting plate 3, the limiting plate 4, and the connecting plate 5, and then take out the corrugated airbag 7 and the sheet 001 together. The operation is simple and efficient.

[0038] Moreover, in the above process, when the corrugated airbag 7 expands, it will sink into the holes and grooves of the sheet 001 to block these holes and grooves, thus preventing dust particles from moving in the holes and grooves of the sheet 001 and causing wear to the holes and grooves or the conductive paths.

[0039] It should be noted that since the corrugated airbag 7 has the ability of elastic deformation, during the process of taking out the sheet 001, when the corrugated airbag 7 contracts and is taken out, the corrugated airbag 7 can be stretched through the connection port 6 to make the two connection ports 6 move away from each other, so that the corrugated airbag 7 changes from a corrugated state to a flattened state. At this time, multiple sheets 001 can be taken at one time without taking them out one by one, thus significantly improving the working efficiency.

[0040] Embodiment 2

[0041] Based on Embodiment 1, as Figure 3 and Figure 7 shown, the gas injected into the corrugated airbag 7 is cold air; each connecting plate 8 is provided with a first communication port 81.

[0042] The thickness at the fold angle of the corrugated airbag 7 is less than other regions.

[0043] The box body 1, the limiting plate 3, the limiting plate 4, and the connecting plate 5 together form a "mouth"-shaped cooling cavity 100; one of the first communication ports 81 is connected to the cooling cavity 100.

[0044] The box body 1, the limiting plate 3, the limiting plate 4, and the connecting plate 5 are all provided with rounded corners, which helps the cold air in the cooling cavity 100 to flow smoothly and prevents the cold air from being stuck at the internal fold angle of the box body 1 and unable to flow smoothly.

[0045] The side wall of the box body 1 is provided with a deflation valve, and the deflation valve is connected to the cooling cavity 100. When the temperature of the cold air in the cooling cavity 100 rises, the deflation valve can be opened first to discharge the air in the cooling cavity 100 and continuously supply new cold air into the corrugated airbag 7 to ensure the cooling and heat dissipation effects of the cooling cavity 100 and the corrugated airbag 7 on the sheet 001.

[0046] The specific working process of the present invention:

[0047] During the storage process of the sheet 001, due to the dense storage of the sheet 001, when the external environmental temperature is too high, the sheet 001 in the box body 1 will also generate a certain amount of heat.

[0048] Therefore, when the air pump of the control peripheral injects air into the wavy airbag 7 through the connecting plate 8 and the connecting port 6, the air at room temperature is adjusted to cold air; specifically, cold air is injected into the wavy airbag 7 in turn from the connecting port 81, the connecting plate 8 and the connecting port 6 on the left, and the cold air in the wavy airbag 7 is discharged in turn from the connecting port 6, the connecting plate 8 and the connecting port 81 on the right. In this way, after the cold air fills the wavy airbag 7, it will be transported from the connecting port 81 on the right to the cooling cavity 100, so that the cooling cavity 100 is also filled with cold air. In this way, the cold air circulating in the wavy airbag 7 is used to perform wrap-around cooling and heat dissipation on the plate 001, and at the same time, the cold air circulating in the cooling cavity 100 is used to perform surround cooling on the outer side of the wavy airbag 7 and the inner wall of the box 1, thereby achieving good cooling and heat dissipation effects and avoiding damage to the plate 001 in the box 1 due to excessive heat.

[0049] It should be noted that, since the thickness of the wavy airbag 7 at the folded corners is smaller than that of other areas, after the wavy airbag 7 is expanded as a whole, the air injected into it will cause the wavy airbag 7 to expand toward each other and contact with each other (such as Figure 7 As shown), the side of the plate 001 is wrapped, the plate 001 is further wrapped, and the side of the plate 001 is cooled, thereby further improving the cooling and heat dissipation effect of the plate 001.

[0050] Example 3

[0051] On the basis of Example 2, Figure 3 As shown, it also includes a dust collection plate 10 and a dust collection plate 2 11; the dust collection plate 10 is provided on one side of the wavy airbag 7; the dust collection plate 2 11 is provided on the other side of the wavy airbag 7; the dust collection plate 10 and the dust collection plate 2 11 both have elastic deformation capabilities; the dust collection plate 10 and the dust collection plate 2 11 are each provided with a plurality of dust collection holes; each connecting plate 8 is also provided with a connecting port 2 82 and a connecting port 3 83.

[0052] It also includes a rectangular airbag 20; the box body 1, the limiting plate 4 and the connecting plate 5 are jointly provided with at least two symmetrically distributed rectangular airbags 20.

[0053] The specific work of the present invention:

[0054] During the expansion of the wavy airbag 7, the wavy airbag 7 drives the dust collection plate 1 10 and the dust collection plate 2 11 to approach the surface of the plate 001; when the wavy airbag 7 is expanded, the dust collection plate 1 10 and the dust collection plate 2 11 also fit the surface of the plate 001; at this time, the external air pump is controlled to provide suction to the dust collection plate 1 10 and the dust collection plate 2 11 through the connecting port 2 82 and the connecting port 3 83 on both sides; in this way, the dust particles on the surface of the plate 001 and in the hole grooves are sucked through the dust collection plate 1 10 and the dust collection plate 2 11, so that the dust particles enter the dust collection plate 10 and the dust collection plate 2 11, and then are drawn out through the connecting port 2 82 and the connecting port 3 83 on both sides, thereby clearing the dust particles attached to the surface of the plate 001 and in the hole grooves, and avoiding the situation in which the dust particles attached to the surface of the plate 001 scratch the conductive path due to the shaking of the box 1 during the storage and transportation of the plate 001.

[0055] It is important to note that before placing the wavy airbag 7 within the box 1, the rectangular airbag 20 is first controlled to contract. Once the wavy airbag 7 is within the box 1, the rectangular airbag 20 is then controlled to expand, supporting and limiting the wavy airbag 7. Before removing the wavy airbag 7 from the box 1, the rectangular airbag 20 is first controlled to contract, causing the left rectangular airbag 20 to contract to the left and the right rectangular airbag 20 to contract to the right. This creates recessed notches on the left and right sides of the wavy airbag 7, making it easier to remove.

[0056] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
