Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board production technology, specifically a cooling treatment device for flexible circuit board production. Background Technology

[0002] Flexible printed circuit boards (FPCBs), also known as flexible boards, are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bendability. FPCBs have a wide range of applications, including consumer electronics such as smartphones, tablets, and smartwatches, where their flexibility allows for more compact internal layouts and thinner designs.

[0003] During the production of flexible printed circuit boards (FPCBs), the temperature rises, which can affect subsequent processing steps. Therefore, cooling is necessary. However, the current cooling method is to use a fan to blow air onto the FPCB to dissipate heat. This method is slow and the cooling effect is not obvious. Moreover, the FPCB is usually placed on a table, which can only cool a single surface of the FPCB. The heat on the bottom surface of the FPCB is difficult to dissipate quickly. Therefore, improvements are urgently needed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling treatment device for flexible circuit board production, comprising a device body, and further comprising...

[0006] The C-shaped processing frame is fixed to one side of the main body of the device. The top and bottom of the C-shaped processing frame are provided with air inlet slots. A perforated plate is fixed to one side of the air inlet slot, and a fan is installed on the surface of the perforated plate.

[0007] A cooling structure is provided inside the air inlet channel. The cooling structure includes a cooling frame, a serpentine cooling pipe, a water inlet pipe, and a water outlet pipe. The serpentine cooling pipe is installed in the cooling frame inside the air inlet channel, and the water inlet pipe and the water outlet pipe are respectively located at both ends of the serpentine cooling pipe.

[0008] A clamping structure is disposed inside a C-shaped processing frame. The clamping structure includes a clamping plate and a rubber clamping block, the rubber clamping block being fixed to the surface of the clamping structure.

[0009] The drive structure is located on one side inside the C-shaped processing frame. The drive structure includes a bidirectional lead screw, a drive arm, and a motor. The bidirectional lead screw is installed on one side inside the C-shaped processing frame. The drive arm is fitted onto the outer wall of the bidirectional lead screw and is threadedly engaged with the bidirectional lead screw. One end of the drive arm is fixedly connected to a clamping plate. The motor is installed at the top of the C-shaped processing frame, and the output end of the motor is fixedly connected to the bidirectional lead screw.

[0010] Preferably, a dustproof mesh plate is provided on the other side of the air inlet channel, and the outer surface of the dustproof mesh plate is closely attached to the inner surface of the air inlet channel to facilitate dust filtration of the incoming air.

[0011] Preferably, the dustproof mesh is fixed with ear plates on both sides, and the ear plates extend into the positioning groove on the inner wall of the air inlet channel, which facilitates the installation and fixing of the dustproof mesh.

[0012] Preferably, a slot is provided inside the C-shaped processing frame on one side of the positioning groove, and a spring is installed inside the slot. One end of the spring is fixed with an L-shaped locking plate, and one end of the L-shaped locking plate extends to the surface of the ear plate.

The motor drives the bidirectional lead screw to rotate, causing the drive arm to move the clamping structure closer to the flexible circuit board. The clamping structure consists of a clamping plate and rubber clamps. The clamping plate drives the rubber clamps to clamp and fix the flexible circuit board from above and below, thus facilitating the suspension of the flexible circuit board and providing heat dissipation space on both its upper and lower surfaces. A fan operates to blow air, and the ventilation openings inside the clamping plate allow the air blown by the fan to reach the upper and lower surfaces of the flexible circuit board. At this time, the external air passes through the dustproof mesh and then through the air inlet channel. Since the air inlet channel has a cooling structure, the coolant from the external refrigeration equipment enters through the inlet pipe and flows into the serpentine cooling pipe to cool the air, reducing its temperature. The coolant is discharged from the outlet pipe. By cooling the air, the air blown towards the flexible circuit board has low-temperature characteristics, resulting in fast and efficient cooling of the flexible circuit board. Moreover, by cooling both the upper and lower surfaces of the flexible circuit board, the flexible circuit board is cooled quickly, more comprehensively, and effectively. Attached Figure Description

[0028] The clamping structure 12 is disposed inside the C-shaped processing frame 2. The clamping structure 12 includes a clamping plate 13 and a rubber clamping block 14, which is fixed to the surface of the clamping structure 12.

[0029] The drive structure 3 is located inside the C-type processing frame 2 on one side. The drive structure 3 includes a bidirectional lead screw 4, a drive arm 5, and a motor 6. The bidirectional lead screw 4 is installed inside the C-type processing frame 2 on one side. The drive arm 5 is fitted on the outer wall of the bidirectional lead screw 4 and is threadedly engaged with the bidirectional lead screw 4. One end of the drive arm 5 is fixedly connected to the clamping plate 13. The motor 6 is installed at the top of the C-type processing frame 2 and the output end of the motor 6 is fixedly connected to the bidirectional lead screw 4.

[0030] Specifically, the flexible circuit board is placed between the clamping structures 12 inside the C-shaped processing frame 2. The motor 6 drives the bidirectional lead screw 4 to rotate, so that the drive arm 5 drives the clamping structure 12 to move closer to the flexible circuit board. The clamping structure 12 is composed of a clamping plate 13 and a rubber clamping block 14. The clamping plate 13 drives the rubber clamping block 14 to clamp and fix the flexible circuit board from above and below, so as to facilitate the suspension of the flexible circuit board and give both its upper and lower surfaces heat dissipation space.

[0031] A dustproof mesh plate 9 is provided on the other side of the air inlet channel 7, and the outer surface of the dustproof mesh plate 9 is closely attached to the inner surface of the air inlet channel 7.

[0032] Ear plates 21 are fixed on both sides of the dustproof mesh plate 9, and the ear plates 21 extend into the positioning groove 20 on the inner wall of the air inlet groove 7;

[0033] The C-shaped processing frame 2 on one side of the positioning groove 20 is provided with a slot 22, and a spring 23 is installed inside the slot 22. One end of the spring 23 is fixed with an L-shaped locking plate 24, and one end of the L-shaped locking plate 24 extends to the surface of the ear plate 21.

[0034] Specifically, by pulling the L-shaped locking plate 24 to remove it from the surface of the ear plate 21 and retract it into the slot 22, the dustproof mesh plate 9 can be removed from the air inlet slot 7 for cleaning.

[0035] There are four rubber clamping blocks 14, which are distributed at the corner positions on the surface of the clamping plate 13;

[0036] The clamping plate 13 has a ventilation opening slot 15 inside, and the ventilation opening slot 15 has a rectangular structure.

[0037] Specifically, the fan 11 operates to blow air, and the ventilation opening slot 15 inside the clamping plate 13 is designed to allow the air blown out by the fan 11 to blow onto the upper and lower surfaces of the flexible circuit board.

[0038] One end of the inlet pipe 18 and the outlet pipe 19 are connected to the serpentine cooling pipe 17, and the other end of the inlet pipe 18 and the outlet pipe 19 extend to the outside of the C-shaped processing rack 2.

[0039] Specifically, after being filtered by the dustproof mesh plate 9, the external air passes through the interior of the air inlet channel 7. Since the air inlet channel 7 is equipped with a cooling structure 8, the coolant of the external refrigeration equipment enters from the water inlet pipe 18 and flows into the serpentine cooling pipe 17 to cool the air and reduce its temperature. The coolant is discharged from the water outlet pipe 19. By cooling the air, the air blowing towards the flexible circuit board has low-temperature characteristics, resulting in fast and efficient cooling of the flexible circuit board. Moreover, by cooling the upper and lower surfaces of the flexible circuit board, the flexible circuit board is cooled quickly, resulting in more comprehensive and effective cooling.

[0040] In this embodiment, the flexible circuit board is first placed between the clamping structures 12 inside the C-shaped processing frame 2. The motor 6 drives the bidirectional lead screw 4 to rotate, causing the drive arm 5 to move the clamping structure 12 closer to the flexible circuit board. The clamping structure 12 consists of a clamping plate 13 and rubber clamps 14. The clamping plate 13 drives the rubber clamps 14 to clamp and fix the flexible circuit board from above and below, thus facilitating the suspension of the flexible circuit board and providing heat dissipation space on both its upper and lower surfaces. The fan 11 operates to blow air, and the ventilation opening slots 15 inside the clamping plate 13 facilitate the airflow from the fan 11. As the air flows towards the upper and lower surfaces of the flexible circuit board, external air passes through the dustproof mesh 9 and then through the interior of the air inlet channel 7. Since the air inlet channel 7 is equipped with a cooling structure 8, the coolant from the external refrigeration equipment enters through the water inlet pipe 18 and flows into the serpentine cooling pipe 17 to cool the air, reducing its temperature. The coolant is then discharged through the water outlet pipe 19. By cooling the air, the air blowing towards the flexible circuit board has low-temperature characteristics, resulting in fast and efficient cooling of the flexible circuit board. Furthermore, by cooling the upper and lower surfaces of the flexible circuit board, the flexible circuit board is cooled rapidly, resulting in more comprehensive and effective cooling.

[0041] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
