A packaging mold for FPC

Abstract

This invention discloses an FPC packaging mold and packaging process, relating to the field of FPC packaging molds. It includes a lower mold base and an upper mold base, with the lower mold base located below the upper mold base. A lower mold body is provided on the upper outer surface of the lower mold base. One end of the lower mold body has a connecting guide groove, a vent hole, and a glue groove. In this FPC packaging mold and packaging process, an air cylinder can be connected to the vent hole via an air guide pipe. When the air cylinder draws air, it can be used to tighten the FPC through the vent hole, facilitating FPC fixation. When the air cylinder vents air, it can be used to blow air through the vent hole, facilitating FPC demolding. This makes it convenient to use. Furthermore, the connecting rod can move with the upper mold body, allowing the air cylinder to complete both air drawing and venting, simplifying the packaging process and improving packaging efficiency. The shape and position of the movable module are adapted to the FPC to be packaged. By increasing the number of movable modules on the upper mold body, processing efficiency can be improved.

Description

Technical Field

[0001] This invention relates to the field of FPC packaging molds, and more specifically to an FPC packaging mold. Background Technology

[0002] FPC, also known as flexible printed circuit board, is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film as the substrate. During the processing of FPC, it needs to be encapsulated, and special encapsulation molds are required for encapsulation. However, existing encapsulation molds are not readily available.

[0003] Chinese invention patent application number CN201220746038.X discloses an FPC packaging mold, including an upper mold and a lower mold. The upper mold has a movable module that can move upward to make room for the encapsulation part when the mold is closed. The shape and position of the movable module are adapted to the components on the FPC to be packaged. The upper mold has an injection port, and the lower mold has a vent hole that can suck the FPC onto the lower mold. The guide post on the upper mold and the guide sleeve on the lower mold are adapted to each other. In use, the mold is assembled with a low-pressure packaging machine. When the mold is closed, the movable module of the upper mold moves upward to make room for the encapsulation part without damaging the components. The air suction port design of the lower mold sucks the FPC onto the lower mold and fixes it firmly. However, this FPC packaging mold has a small number of packaging stations and low processing efficiency. In addition, it can only suck air to fix the FPC, which is not convenient for demolding the FPC. Therefore, we propose an FPC packaging mold. Summary of the Invention

[0020] like Figure 1-3 As shown, an FPC packaging mold includes a lower mold base 1 and an upper mold base 2. The lower mold base 1 is located below the upper mold base 2. A lower mold body 3 is provided on the upper outer surface of the lower mold base 1. A docking guide groove 4, a vent hole 5, and a glue groove 6 are provided on the outer surface of one end of the lower mold body 3. The vent hole 5 is located on both sides of the glue groove 6, and the docking guide groove 4 is located on both sides of the vent hole 5. Air cylinders 7 are provided on both outer surfaces of the lower mold body 3. An air guide pipe 8 is provided on the outer surface of one end of the air cylinder 7, and a connecting rod 9 is provided on the other end of the air cylinder 7. A fixing block 10 is provided between the connecting rod 9 and the upper mold base 2. An upper mold body 11 is provided on the lower outer surface of the upper mold base 2. A glue injection port 12 is provided in the middle of both the upper mold base 2 and the upper mold body 11. A docking guide post 13 and a movable module 14 are provided on the lower outer surface of the upper mold body 11. The docking guide post 13 is located on both sides of the movable module 14. A piston 15 is provided in the middle of the air cylinder 7.

[0021] Furthermore, both outer surfaces of the lower mold body 3 are detachably connected to the outer wall of the air cylinder 7. There are four sets of air cylinders 7. When in use, the air cylinders 7 can be driven by the connecting rod 9 to draw in and expel air. The air cylinders 7 can be connected to the vent hole 5 through the air guide pipe 8. When the air cylinders 7 draw in air, the FPC can be tightened through the vent hole 5, which is convenient for fixing the FPC. When the air cylinders 7 expel air, air can be blown through the vent hole 5, which is convenient for demolding the FPC. It is more convenient to use. Moreover, the connecting rod 9 can move with the upper mold body 11 to make the air cylinders 7 complete the drawing in and expelling of air, making the packaging process simpler and improving the packaging efficiency.

[0022] Furthermore, one end of the outer surface of the air cylinder 7 is detachably connected to one end of the outer surface of the air guide tube 8, and the inner wall of the air cylinder 7 is movably connected to the outer wall of the piston 15. When in use, the air guide tube 8 can facilitate the connection between the air cylinder 7 and the air vent 5, and air can be drawn in and vented through the air guide tube 8.

[0023] Furthermore, the connecting rod 9 is detachably connected to the upper mold base 2 via the fixing block 10, and the outer surface of one end of the connecting rod 9 is detachably connected to the outer surface of one end of the piston 15. The fixing block 10 facilitates the connection of the connecting rod 9 during use, making it convenient to assemble and disassemble the connecting rod 9.

[0024] Furthermore, the lower outer surface of the upper mold body 11 is fixedly connected to the outer surface of one end of the docking guide post 13. There are four sets of docking guide posts 13. The lower mold body 3 and the docking guide groove 4 are integrally formed structures. There are four sets of docking guide grooves 4. The docking guide posts 13 and the docking guide groove 4 can facilitate docking between the upper mold body 11 and the lower mold body 3 during use.

[0025] Furthermore, the lower mold body 3 and the vent hole 5 are integrally formed structures. The lower outer surface of the upper mold body 11 and one outer surface of the movable module 14 can be detachably connected. The shape and position of the movable module 14 are adapted to the FPC to be packaged. By increasing the number of movable modules 14 on the upper mold body 11, the processing efficiency can be improved.

[0026] Furthermore, the injection port 12 passes through the upper mold base 2 and the upper mold body 11, and the lower mold body 3 and the glue groove 6 are integrally formed. The injection port 12 facilitates glue injection during use and makes it convenient to encapsulate the FPC.

[0027] Working principle

[0028] This invention relates to an FPC encapsulation mold. In use, the connecting rod 9 can be fixed to the upper mold base 2 via the fixing block 10. When the upper mold base 2 moves downwards, the connecting rod 9 drives the piston 15 to move downwards, thereby causing the air cylinder 7 to draw in air. During use, the air cylinder 7 is connected to each set of vent holes 5 via the air guide pipe 8. The air cylinder 7 drawing in air can cause air to be drawn into the vent holes 5, thus facilitating the suction and securing of the FPC. This allows the FPC to adhere to the lower mold body 3 until the upper mold body 11 is inserted into the lower mold body 3 via the docking guide post 13. Within the mating guide groove 4 of the lower mold body 3, the mating and sealing of the upper mold body 11 and the lower mold body 3 are completed. Then, glue can be injected through the injection port 12 and flow through the glue groove 6. The FPC is then encapsulated in the movable module 14. After encapsulation, the upper mold base 2 can be moved upward, causing the upper mold base 2 to drive the connecting rod 9. At this time, the connecting rod 9 will push the moving piston 15 to move upward. At this time, the air cylinder 7 will exhaust air through the air guide pipe 8 at the air vent 5, thereby allowing the FPC to detach from the lower mold body 3, thus completing the demolding.
