[0019] The embodiments of the utility model will be described in detail below, with reference to Figure 1The embodiment of the utility model provides a device for preventing small product bulk material, include: tray 100, multilayer sheet PET film 200, multilayer pressure sensitive adhesive 300 and flexible printed circuit board 400 (hereinafter referred to as FPC), multilayer sheet PET film 200 is stacked in tray 100 inside layer by layer;Pressure sensitive adhesive 300 is attached to the upper end surface of sheet PET film 200;Flexible printed circuit board 400 is sheet structure, and flexible printed circuit board 400 is attached on the composite structure of sheet PET film 200 and pressure sensitive adhesive 300. The conventional tray 100 is in the process of handling and transportation, because small product size is small, easily falls out from tray 100, causes product loss or damage. The utility model discloses a FPC 400 sheet structure and is combined with PET film 200 and pressure sensitive adhesive 300, forms a stable multilayer composite structure, ensures that even very small product also can not fall out in the process of transportation and handling. This not only reduces the loss of product, also improves the security and reliability of logistics. At the same time, the combination of multilayer PET film 200 and pressure sensitive adhesive 300 makes FPC 400 can be stacked in sheet material, of course, the utility model does not limit the specific number of stacked layers, preferably, the composite structure can be stacked 5 layers high. By FPC 400 sheet structure stacking 5 layers high, can significantly improve the space utilization of tray 100, reduces the use amount of tray 100. Compared with the single bulk FPC 400 in the conventional tray 100, this design can greatly reduce the number of tray 100, reduce the consumption of packaging materials, thereby reducing the cost. At the same time, the stacking mode can also make full use of storage space, reduce the complexity of inventory management, improve the flexibility of supply chain. This stacking mode not only saves the space of tray 100, but also simplifies the packaging process, reduces manual operation. Customers can directly take out the whole piece of material from tray 100, use layer by layer, avoid the cumbersome operation of taking and tearing film one by one, significantly improve the operation efficiency of customers. Moreover, PET film 200 as a protective layer, can effectively prevent FPC 400 from being affected by external environment in the process of transportation and handling, such as dust, humidity, etc. At the same time, the attachment of pressure sensitive adhesive 300 ensures the close contact between FPC 400 and PET film 200, avoids the occurrence of pressure sensitive adhesive 300 reverse separation phenomenon, guarantees the stability of product quality. This is particularly important for sensitive products such as electronic components, which can effectively prolong the service life of the product.

[0020] Further, the device for preventing small product bulk material provided by the utility model further comprises a device body 500, which is located above the flexible printed circuit board 400. The presence of the device body 500 can provide additional physical protection for the FPC 400 during transportation and handling, preventing the FPC 400 from being impacted or collided by external forces. Especially in the case of multi-layer stacking, the device body 500 can effectively disperse external forces, avoiding damage to the FPC 400 due to uneven stress. This is particularly important for electronic products that require high reliability, ensuring that the quality and performance of the product are not affected. Further, the size and thickness of the PET film 200 are customized according to the specifications of the flexible printed circuit board 400, so that the flexible printed circuit board 400 can be flatly attached to the PET film 200. By customizing the size and thickness of the PET film 200, the specific specifications of the FPC 400 can be accurately matched, ensuring that the FPC 400 can be flatly attached to the PET film 200. This not only improves the aesthetics of the FPC 400, but also avoids deformation or damage problems caused by mismatch between the PET film 200 and the FPC 400. For electronic products that require high precision, this design can ensure the stability and reliability of the FPC 400 during subsequent processing and use. At the same time, the size and thickness of the PET film 200 are customized to form a tighter bond with the pressure-sensitive adhesive 300, ensuring that the adhesion between the FPC 400 and the PET film 200 is more stable. Further, the thickness of the pressure-sensitive adhesive 300 is uniform, so that the adhesion between the flexible printed circuit board 400 and the sheet PET film 200 is stable. The uniform thickness of the pressure-sensitive adhesive 300 can ensure that the adhesion of each FPC 400 is the same, avoiding the problem of poor adhesion caused by uneven thickness of the pressure-sensitive adhesive 300. This not only improves production efficiency, but also reduces the rate of defective products and reduces production costs. For manufacturers of large-scale production, this design can significantly improve the degree of automation of the production line and improve overall production efficiency.

[0021] Further, the structure of the PET film 200 combined with the pressure-sensitive adhesive 300 is processed using an optimized surface mount path. The optimized surface mount path includes SMT, online testing of the connecting plate, bonding of the pressure-sensitive adhesive 300, punching of the FPC 400, and packaging in sequence. In this way, rapid shipment is achieved. By using the optimized surface mount path, the production efficiency of the FPC 400 can be significantly improved. Specifically, the processes of SMT (surface mount technology), online testing of the connecting plate, bonding of the pressure-sensitive adhesive 300, punching of the FPC 400, and packaging can be efficiently processed through the optimized path, reducing production time and improving production speed. For manufacturers who need mass production, this can significantly reduce production costs and improve market competitiveness. Further, the flexible printed circuit board 400 in sheet form is placed in the tray 100 in a stacked manner during transportation and storage to reduce the use of packaging materials. By stacking the FPC 400 in a sheet structure in the tray 100, the use of packaging materials can be significantly reduced. Compared to the traditional tray 100 with individual loose FPC 400, this design can significantly reduce the number of trays 100 and reduce the consumption of packaging materials, thereby reducing costs. At the same time, the stacked manner can also make full use of warehouse space, reduce the complexity of inventory management, and improve the flexibility of the supply chain. Further, the pressure-sensitive adhesive 300 is made using a blue film integrated process. The pressure-sensitive adhesive 300 in the form of a blue film integrated sheet has been pre-processed into a sheet shape and can be directly used in the bonding process of the FPC 400, reducing the time and steps of on-site processing. This not only improves production efficiency but also reduces manual intervention and reduces production costs. For manufacturers who need mass production, this design can significantly improve the automation level of the production line and improve overall production efficiency.
