According to the number of layers of the circuit board, it can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards. During the production process of PCB boards, the finished PCB boards are often placed in dedicated storage devices for storage, so as to extend the shelf life of the PCB boards.

[0003] Utility model patent number CN220640772U discloses a transport rack for PCB board processing, comprising a transport box with a door hinged on one side, four universal wheels fixedly connected to the bottom of the box, a lower fixing frame mounted inside the box, and a plurality of first limiting rods fixedly connected to the interior of the box. Each first limiting rod has an upper fixing frame fixedly connected to its outer surface.

[0055] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0056] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0057] Example 1:

[0058] like Figure 1-Figure 3 As shown, this embodiment provides a transport rack for PCB board processing, including:

[0059] Transport box 1, used to store PCB boards;

[0060] Universal wheels 2 are arranged around the bottom of the transport box 1;

[0061] Transport box 2 3, arranged on top of transport box 1;

[0062] The clamping mechanism 5 is provided inside the transport box 1 and the transport box 3 and is used to clamp the PCB board;

[0063] The clamping mechanism 4 is provided on the transport box 1 and the transport box 2 3, and is used to install the transport box 2 3 on the transport box 1, and to stack the transport boxes according to the number of PCB boards to be transported;

[0064] The clamping mechanism 4 includes:

[0065] There are four sets of fixing blocks 41, which are symmetrically arranged on the left and right sides of the transport box 1;

[0066] A guide rod 42 is provided on the fixing block 41;

[0067] The clamping block 43 is slidably arranged between the two guide rods 42 on the same side;

[0068] Buckles 44 are provided at the front and rear ends of the left and right sides of the transport box 2 3 , and the buckles 44 are connected to the clamping blocks 43 ;

[0069] The return spring 45 is sleeved on the guide rod 42 and disposed between the clamping block 43 and the fixing block 41;

[0070] The pushing block 46 is disposed outside the locking block 43 .

[0071] In this technical solution, transport box 1 and transport box 2 are primarily used as containers for PCBs. They provide a secure space to house and protect the PCBs, preventing them from damage or contamination during transport and storage. Universal wheels 2 are mounted around the bottom of transport box 1, providing flexible mobility for the transport rack. These wheels allow users to easily move and position the rack within the work area, effectively handling the processing and transportation of PCBs. Transport box 2 3, located on top of transport box 1, increases the transport capacity of PCBs. By stacking transport box 2 3 on top of transport box 1, more PCBs can be transported without increasing floor space. A clamping mechanism 5 is located inside transport boxes 1 and 2, securing the PCBs and preventing them from accidentally moving or being damaged. A snap-fit ​​mechanism 4 is located between transport boxes 1 and 2, ensuring they remain securely connected. Specifically, it includes: four groups of fixed blocks 41 are symmetrically arranged on the left and right sides of the transport box 1, serving as the basic support of the clamping mechanism 4; the guide rods 42 are arranged on the fixed blocks 41, which are used to guide and support the movement of the clamping blocks 43; the clamping blocks 43 are slidingly arranged between the guide rods 42; through the action of the return spring 45 and the push block 46, the transport box 2 3 can be firmly connected to the transport box 1 when needed; the buckles 44 are arranged at the front and rear ends of the left and right sides of the transport box 2 3, and are clamped and connected with the clamping blocks 43 to ensure the stability and safety of the clamping mechanism 4.

[0072] When the PCB boards need to be transported, first place the PCB boards in the transport box 1 and the transport box 2 3, and clamp the PCB boards through the clamping mechanism 5 to ensure that the PCB boards remain in a stable position during transportation and movement to prevent them from accidental movement or damage. According to the number of PCB boards, choose to add the transport box 2 3, place the transport box 2 3 on the top of the transport box 1, and connect them through the clamping mechanism 4, so that the transport box 2 3 is stably installed on the transport box 1. After the PCB boards are stored, the user pushes the transport box 1, and the transport box 1 moves on the ground through the universal wheels 2. The universal wheels 2 allow the user to easily move within the work area to effectively handle the processing and transportation of the PCB boards. After the PCB boards are transported to the location where they need to be processed, the PCB boards are unloaded. When the transport box 2 3 is no longer needed, it is used to push the push block 46, and the push block 46 drives the card The block 43 moves inward along the guide rod 42, and the return spring 45 is compressed. At this time, the block 43 is disconnected from the buckle 44, and the user can remove the transport box 2 3 from the transport box 1 1. When the transport box 2 3 is needed, the transport box 2 3 is placed on the top of the transport box 1 1, the buckle 44 is aligned with the block 43, and the block 43 is released. Under the reset action of the return spring 45, the block 43 moves outward along the guide rod 42, and the block 43 moves outward until it is connected with the buckle 44, so that the transport box 2 3 is installed on the transport box 1 1, thereby increasing the transportation capacity of the PCB boards. By stacking the transport box 2 3 on the transport box 1 1, more PCB boards can be transported without increasing the ground space occupied, thereby improving transportation efficiency, reducing labor costs, ensuring the safety and stability of the PCB boards during the processing, and making it suitable for various production environments and needs.

[0073] Example 2:

[0074] This embodiment provides a transport rack for PCB board processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0075] like Figure 2 As shown, in this embodiment, the clamping mechanism 5 is optimized to be composed of symmetrically distributed clamping blocks 51 and an adjustment mechanism 6 for adjusting the relative positions of the clamping blocks 51, and the clamping blocks 51 are arranged inside the transport box 1 and the transport box 2 3.

[0076] In this technical solution, the clamping mechanism 5 is composed of symmetrically distributed clamping blocks 51, which are located inside the transport box 1 and the transport box 2 3. The function of the clamping blocks 51 is to fix and clamp the PCB board to prevent it from moving or being damaged during transportation, thereby improving production efficiency and product quality.

[0077] like Figure 2 As shown, in this embodiment, the adjustment mechanism 6 is optimized and includes:

[0078] Guide rails 61 are provided on the upper and lower sides of the interior of transport box 1 1 and transport box 2 3 . There are a plurality of guide rails 61 , which are evenly spaced along the length of transport box 1 1 and transport box 2 3 . The clamping block 51 is slidably connected to the guide rails 61 .

[0079] Support plates 62 are provided on the front and rear sides of the guide rail 61;

[0080] The slide rod 63 is slidably disposed on the support plate 62, and the slide rod 63 passes through and extends out of the support plate 62, and the slide rod 63 is fixedly connected to the clamping block 51;

[0081] The return spring 64 is sleeved on the slide rod 63 and disposed between the clamping block 51 and the support plate 62 .

[0082] In this technical solution, guide rails 61 are arranged on the upper and lower sides of the interior of transport box 1 and transport box 2 3. The guide rails 61 are evenly spaced along the length direction of the transport box to provide sliding support and guidance for the clamping block 51. The support plates 62 are arranged on the front and rear sides of the guide rails 61. The slide rods 63 are slidably arranged on the support plates 62. The slide rods 63 pass through and extend out of the support plates 62 and are fixedly connected to the clamping block 51. The movement of the slide rods 63 enables the clamping block 51 to slide back and forth inside the transport box along the guide rails 61. The return spring 64 is sleeved on the slide rod 63 and is arranged between the clamping block 51 and the support plates 62. The function of the return spring 64 is to provide a restoring force to ensure that the clamping block 51 can stably maintain the clamping force when fixing the PCB board, while also reducing the impact of vibration and vibration on the PCB board.

[0083] Working Principle Overview

[0084] The PCB board is placed in the transport box 1 1 and the transport box 2 3, and the clamping block 51 is adjusted and fixed by the guide rail 61 and the slide bar 63 system. When the PCB board needs to be fixed, the user can adjust the position of the slide bar 63, and the slide bar 63 drives the clamping block 51 to move outward along the guide rail 61, and the return spring 64 is compressed. Then the PCB board is placed between the two clamping blocks 51 on the same side. After placement, the slide bar 63 is released, and under the reset action of the return spring 64, the clamping block 51 moves inward along the guide rail 61 to clamp the PCB board, ensuring that the clamping block 51 can stably maintain the clamping force when fixing the PCB board, so that the clamping block 51 tightly clamps the PCB board. The design of the return spring 64 can adjust the clamping force and maintain its stability and safety during the transportation of the PCB board, so as to effectively protect and fix the PCB board, ensure that it is not damaged or shifted during transportation and processing, thereby improving production efficiency and product quality, and at the same time being able to clamp PCB boards of different sizes.

[0085] Example 3:

[0086] This embodiment provides a transport rack for PCB board processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0087] like Figure 1 As shown, in this embodiment, the front sides of the transport box 1 and the transport box 2 3 are optimized and provided with a protection mechanism 7, which includes:

[0088] Connecting plates 71 are provided at the upper and lower ends of the left sides of transport box 1 and transport box 2 3;

[0089] The door shaft 72 is rotatably arranged between the two connecting plates 71 on the same side;

[0091] The protective door 74 is provided on the rotating plate 73, and the protective door 74 covers the transport box 1 and the transport box 2 3.

[0092] The handle 75 is provided on the protective door 74 .

[0093] In the present technical solution, the design of the protective mechanism 7 is intended to protect the PCB boards from being affected by external objects or conditions during transportation, while also providing convenient access and operation for users. By rotating the door shaft 72, the rotating plate 73 and the protective door 74 on the connecting plate 71 can be opened or closed. When the protective door 74 is closed, they cover and protect the front of the transport box, effectively preventing dust, debris or other external objects from entering the interior of the box, thereby protecting the PCB boards stored inside from contamination or damage. The user can easily rotate the door shaft 72 through the handle 75 to open or close the protective door 74, ensuring the convenience and safety of operation, so that the PCB boards can be quickly accessed when needed without having to worry about additional physical damage or environmental pollution. This not only provides effective protection measures, but also takes into account the user's convenience of use, thereby ensuring that the PCB boards remain safe and intact during transportation and storage.

[0094] Example 4:

[0095] This embodiment provides a transport rack for PCB board processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0096] like Figure 1-Figure 3 As shown, in this embodiment, the optimization further includes a locking mechanism 8, which includes:

[0097] Support frames 81 are provided on the left and right sides of transport box 1 and transport box 2 3;

[0098] The rotating shaft 82 is rotatably disposed at the upper and lower ends of the support frame 81;

[0099] The hinge ball 83 is disposed between the two rotating shafts 82 and is located in the support frame 81;

[0100] The clamping plate 84 is provided at the upper and lower ends of the right side of the protective door 74;

[0101] A clamping rod 85 is provided at the front end of the hinge ball 83 and is clamped between the two clamping plates 84;

[0102] The limiting plate 86 is provided at the front end of the clamping rod 85 , and the limiting plate 86 is in contact with the clamping plate 84 .

[0103] In this technical solution, when it is necessary to lock the protective door 74, the user will manually or automatically push the card rod 85 between the card plates 84 to form a card engagement between the card rod 85 and the card plates 84. At this time, the card rod 85 is fixed at a specific position inside the support frame 81 with the support of the hinge ball 83 and the rotating shaft 82, thereby fixing the protective door 74 at the desired position. The presence of the limit plate 86 ensures that the card rod 85 can only move to the correct position without excessive or insufficient movement, thereby ensuring the safety and stability of the protective door 74. This design can not only effectively fix the protective door 74, but also can be quickly released when needed, making the transport rack for PCB board processing safer and more efficient during operation.

[0104] Example 5:

[0105] This embodiment provides a transport rack for PCB board processing, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0106] like Figure 2-Figure 4 As shown, in this embodiment, the optimization further includes a heat dissipation mechanism 9, which includes:

[0107] The mounting groove 91 is formed on the rear side of the transport box 1 and the transport box 2, and extends outward to penetrate the transport box 1 and the transport box 2;

[0108] The mounting shell 92 is disposed inside the mounting slot 91;

[0109] The motor 93 is disposed in the mounting housing 92;

[0110] A fan 94 is provided on the output shaft of the motor 93 and is located inside the mounting housing 92;

[0111] The dustproof net 95 is disposed on the rear side of the mounting shell 92 .

[0112] In the present technical solution, the mounting slot 91 is provided at the inner rear side of the transport box 1 and the transport box 2 3, and extends outwardly through the two transport boxes. The function of the mounting slot 91 is to provide space for installing the heat dissipation mechanism 9 and to allow the heat dissipation device to effectively absorb and exhaust air. The mounting shell 92 is provided inside the mounting slot 91 and serves as a support and fixing structure for installing the heat dissipation device. The motor 93 is installed inside the mounting shell 92. Its function is to provide power for the heat dissipation mechanism 9 so that the fan 94 can operate. The fan 94 is installed on the output shaft of the motor 93 and is located inside the mounting shell 92. The fan 94 generates airflow through the rotation of the motor 93, thereby accelerating air circulation and improving the heat dissipation effect. The dustproof net 95 is provided on the inner rear side of the mounting shell 92 to prevent dust and other debris from entering the mounting shell 92, which helps to keep the fan 94 and the motor 93 clean and ensure their normal operation and long-term stability.

[0113] Working principle analysis:

[0114] When the transport rack for PCB board processing is operated, the motor 93 is started, and the motor 93 drives the fan 94 to start rotating. As the fan 94 rotates, it generates airflow inside the mounting shell 92. This airflow passes through the channel inside the mounting shell 92, including the through-portion of the mounting slot 91, thereby effectively absorbing heat and dissipating hot air. Through the coordinated action of the motor 93 and the fan 94, the heat dissipation mechanism 9 can quickly and effectively transfer heat from the inside of the transport box to the external environment. This heat discharge ensures that the operating temperature of internal components such as PCB boards remains within a safe range, preventing damage due to overheating. This not only improves the working efficiency of the transport rack, but also enhances its long-term stability and reliability, making it suitable for application scenarios that require long-term operation or high-temperature environments.
