Description

Technical Field

[0001] This application relates to the field of tray fixture technology, and in particular to a circuit board tray fixture. Background Technology

[0002] In the modern electronics manufacturing industry, circuit boards and their connecting wires are core components of electronic products, and their protection during production, transportation, and storage is crucial. To meet the needs of efficient production and quality control, trays specifically designed for placing circuit boards and their connecting wires have emerged, ensuring the integrity and safety of circuit boards during transit.

[0003] Currently, the most common tray fixtures on the market are made of plastic or metal, and use structures such as grooves to fix the circuit boards.

[0004] Regarding the aforementioned technologies, the inventors believe that during transportation, vehicle bumps can easily cause collisions and friction between circuit boards, resulting in damage such as scratches on the circuit board surface, component detachment, or even circuit breakage. This seriously affects the quality and production efficiency of the circuit boards, increasing the company's production costs and product defect rate. Utility Model Content

[0005] The purpose of this application is to provide a circuit board tray fixture to improve the problem that circuit boards are prone to collision and friction, which can cause damage such as scratches on the circuit board surface, component detachment, or even circuit breakage.

[0006] This application provides an electrical circuit board tray fixture, which adopts the following technical solution:

[0007] A circuit board tray fixture includes a tray body, the tray body including a bottom plate and side plates located around the bottom plate. The bottom plate is provided with a plurality of long partitions connected to the side plates at both ends along its length, dividing the tray body into a plurality of cavities. Each cavity of the bottom plate is provided with a set of partitions along the length of the bottom plate. Circuit boards are snapped between the partitions. One side of each partition is connected to the side wall of a long partition, and one set of partitions is connected to the side plate on one side.

[0008] By adopting the above technical solution, the long partition divides the tray into multiple cavities, and the partition further subdivides the space, allowing the circuit boards to be locked between the partitions, thus achieving partitioned fixing of the circuit boards. This helps prevent collisions caused by mixing multiple circuit boards. At the same time, the locking and fixing of the circuit boards by the partitions helps reduce shaking of the circuit boards during transportation, thereby reducing friction and wear and ensuring the integrity of the circuit boards.

[0009] Optionally, an anti-detachment limiting block is provided on one side of the partition plate.

[0010] By adopting the above technical solution, a barrier is provided at the opening after the circuit board is placed, which together with the spacer forms a three-dimensional limit, which helps to prevent the circuit board from falling out, enhances the fixing effect, and provides more reliable protection for the circuit board.

[0011] Optionally, the anti-detachment limiting block is tilted toward the circuit board locking position.

[0012] By adopting the above technical solution, the circuit board can be guided into place quickly during installation. At the same time, compared with the vertically set limit block, the inclined set has a stronger resistance to the circuit board falling out, which helps to further improve the anti-fall performance and ensure the stable fixation of the circuit board.

[0013] Optionally, the tray body, long partition, spacer, and anti-detachment limiting block are all made of pearl cotton.

[0014] By adopting the above technical solution, pearl cotton material is soft and elastic, and can form a buffer layer when the circuit board comes into contact with the tray, absorbing the impact force generated by the collision, reducing the scratches on the circuit board surface and the problem of components falling off, and making up for the defects of traditional plastic or metal materials that are rigid and have poor buffering; at the same time, the material is lightweight and easy to handle and transport.

[0015] Optionally, a placement plate is provided on the bottom surface of the tray body.

[0016] By adopting the above technical solution, a placement plate is set on the bottom surface of the pallet body. The placement plate provides an additional support structure for the pallet, enhances the overall stability of the pallet, makes the pallet less prone to deformation during placement and handling, and indirectly protects the internal circuit board.

[0017] Optionally, the placement plate is provided with a number of insertion rods on the side near the base plate, and the base plate is provided with a number of insertion holes corresponding to the insertion rods.

[0018] By adopting the above technical solution, the placement plate is fixed by the insertion rod and the bottom plate insertion hole. The interference fit ensures that the placement plate is stably installed and is easy to disassemble and assemble, which facilitates the maintenance and replacement of the pallet. At the same time, the placement plate and the pallet body form a whole to jointly support and protect the circuit board.

[0019] Optionally, the outer side wall of the insertion rod is provided with several anti-slip strips.

[0020] By adopting the above technical solution, anti-slip strips are set on the outer wall of the insertion rod, which increases the friction between the insertion rod and the insertion hole, reduces the possibility of the placement plate loosening or falling off during transportation vibration, further enhances the connection reliability between the placement plate and the pallet body, and ensures the stability of the pallet structure.

[0021] Optionally, the bottom surface of the placement plate is provided with several elastic pads.

[0022] By adopting the above technical solution, the elastic pad on the bottom of the pallet is in direct contact with the transport surface. When the vehicle is bumpy, it absorbs vibration energy through its own deformation, reducing the transmission of vibration to the circuit board inside the pallet. Compared with pallets without shock absorption structure, it can significantly reduce the impact of vibration on the circuit board and ensure the safety of the circuit board during transportation.

[0023] In summary, this application includes at least one of the following beneficial technical effects of circuit board tray fixtures:

[0024] 1. The long partition divides the tray into multiple cavities. The partition further subdivides the space, allowing the circuit boards to be snapped between the partitions. This achieves partitioned fixation of the circuit boards, which helps prevent collisions caused by mixing multiple circuit boards. At the same time, the snapping and fixing of the circuit boards by the partitions helps reduce shaking of the circuit boards during transportation, thereby reducing friction and wear and ensuring the integrity of the circuit boards.

[0025] 2. Pearl cotton is soft and elastic, forming a buffer layer when the circuit board comes into contact with the tray, absorbing the impact of the collision, reducing scratches on the circuit board surface and component detachment, and making up for the shortcomings of traditional plastic or metal materials that are rigid and have poor cushioning; at the same time, the material is lightweight and easy to handle and transport.

[0026] 3. The elastic pad on the bottom of the pallet is in direct contact with the transport surface. When the vehicle is bumpy, it absorbs vibration energy through its own deformation, reducing the transmission of vibration to the circuit boards inside the pallet. Compared with pallets without shock absorption structure, it can significantly reduce the impact of vibration on the circuit boards and ensure the safety of the circuit boards during transportation.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below. Example

[0032] A circuit board tray fixture, as shown in the reference Figure 1 The system includes a tray body 1, which serves as the basic structure for supporting the circuit board. The tray body 1 consists of a base plate 11 and side plates 12 surrounding the base plate 11. The base plate 11 and side plates 12 are integrally fixedly connected, forming a container-like structure with a closed bottom and surrounding walls. The base plate 11 has several long partitions 2 along its length, connected to the side plates 12 at both ends. In this embodiment, four partitions are preferred, but more can be used depending on actual needs. These long partitions 2 are integrally formed with the base plate 11 and side plates 12, dividing the tray body 1 into several cavities 3. The four long partitions 2 correspondingly form five cavities 3.

[0033] Reference Figure 2 A set of partition plates 4 are provided along the length of each cavity 3 within the base plate 11. The partition plates 4 are evenly spaced to further subdivide each cavity 3 for more precise fixing of the circuit board. The circuit board is snapped into place between the partition plates 4 to achieve positioning of the circuit board, and the connecting wires on the circuit board are placed in the cavity 3. One side of the partition plate 4 is integrally fixedly connected to the side wall of the long partition plate 2, and one set of partition plates 4 is integrally fixedly connected to the side plate 12. The tray body 1, the long partition plate 2, and the partition plates 4 are all made of pearl cotton.

[0034] Example 2 differs from Example 1 in that:

[0035] Reference Figure 1 One side of the partition 4 is integrally provided with an anti-detachment limiting block 41, which is used to reduce the possibility of the circuit board coming off between the partitions 4 during placement or transportation. The anti-detachment limiting block 41 is inclined towards the position where the circuit board is locked in place. In this embodiment, the inclination angle is preferably 45°, which can better prevent the circuit board from coming off. The tray body 1, the long partition 2, the partition 4, and the anti-detachment limiting block 41 are all made of pearl cotton. Pearl cotton is a foam material with the characteristics of being lightweight, soft, having good cushioning performance, and being antistatic. The tray body 1, the long partition 2, the partition 4, and the anti-detachment limiting block 41 are all sprayed with antistatic liquid.

[0036] Reference Figure 1 , Figure 2 The bottom surface of the pallet body 1 is provided with a placement plate 5, which can be made of rigid plastic to increase the stability and cushioning performance of the pallet. Several insert rods 6 are integrally provided on the side of the placement plate 5 near the bottom plate 11. In this embodiment, four rods are preferably evenly and symmetrically arranged. The bottom plate 11 has several insertion holes 111 corresponding to the insert rods 6. The insert rods 6 and the insertion holes 111 are connected by an interference fit to fix the placement plate 5 to the bottom surface of the pallet body 1.

[0037] Reference Figure 2 , Figure 3The outer wall of the insertion rod 6 is provided with several anti-slip strips 61, which can increase the friction between the insertion rod 6 and the insertion hole 111. The bottom surface of the placement plate 5 is fixed with several elastic pads 7 by countersunk bolts. In this embodiment, four pads are preferably evenly and symmetrically arranged to facilitate stable placement. The elastic pads 7 are generally made of rubber and have good elasticity and cushioning performance.

[0038] The implementation principle of this application embodiment is as follows:

[0039] In practical use, the circuit board tray fixture achieves precise positioning through a multi-layer partition structure. The cavity 3 formed by the long partition 2 and the spacer 4, as well as the slot, can fix the circuit board. The anti-detachment limiting block 41 is tilted to prevent the circuit board from falling out. The tray body 1 and all components are made of pearl cotton, which can effectively buffer the impact of collisions. The placement plate 5 is fixed to the bottom plate 11 by the insertion rod 6 through an interference fit. The elastic pad 7 on its bottom surface can absorb the vibration energy during transportation. All components work together to prevent collisions and friction between circuit boards, ensuring the safety of circuit board transportation.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
