Description

Technical Field

[0001] The utility model relates to the technical field of FPC packaging tooling, and particularly relates to a continuous packaging device for FPC. Background Art

[0002] A flexible printed circuit (FPC) is a printed circuit made of a flexible insulating substrate and has many advantages that rigid printed circuit boards do not have. For example, it can be freely bent, wound, and folded, can be arranged arbitrarily according to the requirements of the spatial layout, and can move and stretch arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection. By using FPC, the volume of electronic FPC can be greatly reduced, which meets the needs of the development of electronic FPC towards high density, miniaturization, and high reliability. Therefore, FPC has been widely used in the fields of aerospace, military, mobile communication, laptop, computer peripherals, PDA, digital camera, etc. or on FPC.

[0003] For example, the patent document with the application number CN115635644A discloses a packaging mold and a packaging process for FPC, which includes a lower mold base and an upper mold base. The lower mold base is located below the upper mold base, and the outer surface of the upper end of the lower mold base is provided with a lower mold body. The outer surface of one end of the lower mold body is provided with a docking guide groove, a ventilation hole, and a glue groove. This mold can perform the packaging process of multiple workpieces at one time by opening a plurality of cavities arranged in an array on the mold surface to improve the packaging efficiency. However, after completing a batch of injection molding packaging, this mold needs to stop the machine to remove the workpieces and load another batch of workpieces, and does not effectively reduce the downtime interval. During the continuous packaging process, a large amount of downtime is still required for independent workpiece disassembly and replacement operations, which greatly limits the comprehensive packaging efficiency during large-scale processing. In addition, since the packaging material needs a certain time to cool and solidify, and the existing mold does not have a condensation auxiliary structure, it is necessary to extend the downtime to naturally cool the packaging material on the surface of the workpiece to ensure packaging stability, which further increases the packaging time and reduces the packaging efficiency. Finally, the existing packaging mold does not have an auxiliary material taking structure, which is not convenient to quickly take out the packaged workpieces from the mold, increases the difficulty of workpiece removal, and reduces the comprehensive efficiency of packaging processing.

Preferably, heat exchange fins 63 that can be partially inserted into the encapsulation groove 311 are embedded in the condensation plate 61, and the side of the heat exchange fin 63 facing the encapsulation groove 311 is the heat absorption end.

Preferably, the lower surface of the heat exchange fin 63 is further coated with an anti-adhesion film layer 631 that can prevent the encapsulation material from sticking.

[0038] The working principle of the present application is as follows:

[0039] During the packaging process, the rotary drive motor 32 drives the rotating disc 31 to perform intermittent stepping rotation in a clockwise direction, so that the packaging slots 311 sequentially pass through the disassembly and assembly stations away from the packaging assembly 5, and the workpieces are placed into the packaging slots 311 one by one through manual loading by the staff or by the robotic arm. The rotary drive motor 32 further drives the rotating disc 31 to rotate, so that the packaging slots 311 with the workpieces placed therein move to the packaging station, and the lifting array 52 drives the upper mold body 51 to descend and cover the packaging slots 311, thereby constructing a packaging space. Then, the injection molding module 53 injects the packaging material under slight pressure to encapsulate the surface of the workpiece. Then, the lifting array 52 drives the upper mold body 51 to rise and separate from the rotating disk body 31. Driven by the rotating drive motor 32, the rotating disk body 31 further deflects and moves the workpiece that has been completed by injection molding to the condensation station, so that the condensation plate 61 or the heat exchange plate 63 that rises and falls synchronously with the upper mold body 51 is used to condense and solidify the encapsulated material, thereby improving the stability of the encapsulation layer. During this process, the upper mold body 51 is synchronously performing the injection molding and encapsulation processing on the workpiece in another adjacent encapsulation groove 311. After the condensation and solidification are completed, the further deflection of the rotating disk body 31 drives the workpiece that has completed the encapsulation and condensation treatment to move to the disassembly and assembly station, and the workpiece is pushed out of the encapsulation groove 311 by the rising pushing module 33, so that the staff or the robot can quickly and non-destructively remove the workpiece that has been completed by the encapsulation, thereby reducing the difficulty of disassembly while increasing the disassembly speed, thereby improving the disassembly efficiency and improving the overall encapsulation efficiency. Furthermore, this continuous conveying process allows for the simultaneous encapsulation, solidification, and assembly / disassembly of different workpieces, eliminating the additional processing time associated with separate downtime for assembly / disassembly processes. This shortens the processing cycle and allows for the solidification of the encapsulated workpieces, accelerating the solidification of the encapsulating material and significantly increasing the solidification rate of the encapsulating layer while reducing the additional time required for the encapsulating material to solidify. By synchronizing these different processes, the encapsulation process remains continuous and uninterrupted, effectively improving encapsulation efficiency.

[0040] During the above continuous conveying process, the upper push rod 331 and the sliding ball head 334 rotate with the rotating disk body 31. Thus, when approaching the disassembly and assembly station, the sliding ball head 334 contacts the upper edge of the curved arc plate 351 and is limited. Furthermore, during further deflection, the sliding ball head 334 rises along the path defined by the upper edge contour of the curved arc plate 351, so that the upper push rod 331 rises through the through hole 312 and partially inserts into the encapsulation groove 311, in order to use the upper top net plate 332 to push the workpiece out of the encapsulation groove 311, thereby facilitating the removal of the encapsulated workpiece. And during the rising process of the upper push rod 331, the piston rod 333 located below the port where the air duct 313 penetrates the side wall of the through hole 312 moves upward synchronously to block the port of the air duct 313, thereby releasing the negative pressure adsorption force on the workpiece. After the removal is completed, the further rotation of the rotating disk body 31 drives the sliding ball head 334 to further move and descend along the path defined by the upper edge contour of the curved arc plate 351, so that the piston rod 333 descends synchronously with the upper push rod 331 to release the blocking of the port of the air duct 313, so that the air duct 313 assists the negative pressure module 34 to pump air to adsorb and press the newly placed workpiece on the inner bottom surface of the encapsulation groove 311, thereby realizing the positioning of the workpiece. The above process can perform negative pressure positioning and upper top discharging of the workpiece in zones, thereby improving the accuracy and quality of encapsulation while facilitating the removal of the workpiece.
