[0024] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see Figure 1 and Figure 2 The blister tray 100 includes a support blister unit 10 and a pressing blister unit (not shown). In this application, the blister tray 100 is suitable for storing and transporting flexible printed circuit boards (FPCs). The support blister unit 10 is provided with at least one receiving cavity 101 for placing a product. The receiving cavity 101 is provided with a groove 111 for keeping the product in a predetermined bent state. Specifically, the groove 111 is used to keep the FPC in a predetermined bent state. The groove 111 includes a first bending segment 11 and a second bending segment 12. The first bending segment 11 and the second bending segment 12 are set at a predetermined angle, wherein the predetermined angle is determined according to the installation requirements of the FPC in a wireless charging product. A transition fillet 13 is provided at the connection between the first bending segment 11 and the second bending segment 12. The transition fillet 13 avoids the risk of circuit breakage during the bending process of the FPC.

[0026] In the embodiments of this application, please refer to Figure 3 The groove 111 has a stepped cross-section and includes an upper step 14 and a lower step 15. The upper step 14 and the lower step 15 have different depths. The depth difference between the upper step 14 and the lower step 15 is designed to better guide the FPC to bend along a predetermined trajectory and ensure the accuracy of the bending position.

[0027] Please combine Figure 1 And see Figure 4 The bottom of the supporting vacuum forming unit 10 is provided with a reinforcing rib 102, which is used to improve the structural strength of the supporting vacuum forming unit 10 and ensure that the vacuum forming plate 100 will not be deformed due to external force during the FPC assembly process. The edge of the receiving cavity 101 is provided with a pick-and-place notch 114, which facilitates the operator to load and unload the FPC, while avoiding direct contact with the critical circuit area of ​​the FPC.

[0028] In some embodiments, the pick-and-place notch 114 adopts a rounded transition design to avoid scratches that sharp edges may cause to the FPC. The opening width of the pick-and-place notch 114 is larger than the width of the FPC, which facilitates loading and unloading operations by operators or automated equipment.

[0029] In this embodiment, the bottom of the supporting vacuum forming unit 10 is provided with a plurality of reinforcing ribs 102, which extend along the length of the receiving cavity 101. The reinforcing ribs 102 are arranged in parallel, and the spacing between adjacent reinforcing ribs 102 is equal. This uniformly distributed reinforcing rib structure provides support while ensuring the flatness of the bottom of the receiving cavity 101, preventing the FPC from being damaged due to deformation of the vacuum forming tray 100.

[0030] In this embodiment, the compression molding unit is disposed above the carrier molding unit 10, and the compression molding unit can be detachably connected to the carrier molding unit 10. When the compression molding unit is engaged with the carrier molding unit 10, the FPC can be pressed and fixed in the predetermined bending state, ensuring that the FPC maintains a stable bending shape during transportation.

[0031] In this embodiment, the structural design of the groove 111, combined with the pressing action of the compression molding unit, allows the FPC to be pre-bent and shaped at the factory, eliminating the need for manual bending during assembly by end customers and effectively reducing the risk of FPC breakage due to improper manual operation.

[0032] In the embodiments of this application, please refer to Figure 4 The receiving cavity 101 includes a main receiving portion 112 and an extended receiving portion 113, with a groove 111 disposed between the main receiving portion 112 and the extended receiving portion 113. The depth of the main receiving portion 112 is greater than the depth of the extended receiving portion 113, and the bottom surface of the extended receiving portion 113 is flush with the bottom surface of the groove 111. This depth-differentiation design allows the FPC to be stably placed in the main receiving portion 112, while the extended receiving portion 113 enables a smooth transition of the FPC and guides the FPC to bend naturally along a predetermined path. The width of the upper step 14 is designed to match the FPC wiring distribution, avoiding stress damage to the critical wiring areas of the FPC.

[0033] In this embodiment, the combination of stepped grooves 111 and partitioned receiving cavities 101, along with the support structure of multiple reinforcing ribs 102, ensures both the accuracy of FPC bending and improves the overall structural stability. This design is suitable for wireless charging module applications requiring high bending precision.

[0034] In some embodiments, the carrying blister unit 10 is provided with a misalignment positioning structure (not shown), which includes at least one positioning protrusion or positioning recess. The positioning protrusion or positioning recess prevents misalignment of adjacent blister trays 100 during stacking, ensuring the stability of the blister trays 100 during storage and transportation, thereby effectively protecting the internal FPC products. When multiple blister trays 100 are stacked vertically, the positioning protrusion of the upper blister tray 100 can cooperate with the positioning recess of the lower blister tray 100 to form a reliable positioning constraint.

[0035] To further improve storage efficiency, the positioning protrusions or recesses are evenly distributed along the circumference of the supporting blister unit 10. This evenly distributed design not only enhances stability in the stacked state but also facilitates operators to quickly align and place the blister tray 100.

[0036] In this embodiment, the staggered positioning structure design solves the problem of easy displacement of traditional blister trays 100 during stacking, improving the reliability of protection during warehousing and transportation. At the same time, this design also facilitates automated operation on the production line, improving production efficiency.

[0037] This application provides a blister tray 100, including a support blister unit 10 and a pressing blister unit. The support blister unit is provided with at least one receiving cavity 101 for placing a product. The receiving cavity 101 is provided with a groove 111 for keeping the product in a predetermined bent state. The pressing blister unit is disposed above the support blister unit 10 and can be detachably connected to the support blister unit 10. When the pressing blister unit is fastened to the support blister unit 10, the product can be pressed and fixed in the predetermined bent state. The blister tray 100 provides a groove 111 with a specific structure in the receiving cavity 101 of the support blister unit 10. The groove 111 can guide the product to form a predetermined bent state. When the pressing blister unit is fastened to the support blister unit 10, the product can be securely locked in the predetermined bent state. The above design allows the product to maintain a stable pre-bent state when it leaves the factory, avoiding the need for end customers to manually bend the product during assembly. Furthermore, by pre-setting the product's bending shape, this invention not only significantly improves production efficiency but also effectively reduces the risk of product damage caused by manual operation, ensuring the product's quality stability during transportation and assembly.

[0038] This application also provides an embodiment of packaging equipment. As an application implementation of packaging equipment, the blister tray 100 can be used with an automatic feeding system. On an automated production line, the position of the pick-and-place notch 114 corresponds to the pick-and-place mechanism of the automatic feeding system. Through precise positioning and buffer design, the smooth loading and unloading of FPC during high-speed production is ensured.

[0039] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
