Description

Technical Field

[0001] This utility model relates to the technical field of FPC circuit board processing equipment, specifically to an isolation device for FPC circuit board processing. Background Technology

[0002] As electronic devices become smaller, thinner, and more multifunctional, flexible printed circuit boards (FPCs) are widely used in smartphones, wearable devices, automotive electronics, and other fields due to their bendable, foldable, and space-saving characteristics.

[0003] In the process of FPC circuit board processing, an electroplating process is required. The electroplating process has high requirements for environmental cleanliness, so an isolation device is needed. Existing isolation devices have a simple structure and usually require staff to stand next to the isolation device to manually monitor the electroplating time in real time. If the electroplating time is insufficient, the plating thickness will not meet the standard, while excessive electroplating will result in material waste or a rough plating layer.

A timer is provided on one side of the isolation box, and a lifting assembly is provided at the upper end of the isolation box. The timer and the lifting assembly are connected by an electrical signal. A lifting rod inserted into the isolation box is provided at the output end of the lifting assembly. A bottom rod is provided at the lower end of the lifting rod. Two side plates are symmetrically arranged at both ends of the bottom rod. A guide rod is provided between the two side plates. Multiple clamping assemblies are provided on the guide rod.

[0008] The clamping assembly includes a top block and a clamping block. A first limiting plate and a second limiting plate are symmetrically arranged at the lower end of the top block. A slot is provided between the first limiting plate and the second limiting plate. The clamping block is located inside the slot, and a second locking rod is provided at the front end of the clamping block, which penetrates the first limiting plate. The second locking rod is threadedly connected to the first limiting plate.

[0009] Furthermore, an improvement of this utility model is that the lifting component is a cylinder.

[0010] To improve the applicability of this structure, the following improvements are made to this utility model: the top block is slidably connected to the guide rod, the top block has a through hole through which the guide rod passes, the upper end of the top block has a first locking rod, the first locking rod passes through the top block and its bottom end contacts the guide rod, the first locking rod is threadedly connected to the top block, and both the upper end of the first locking rod and the outer end of the second locking rod have a toggle block, and the cross-section of the guide rod is circular.

[0011] Furthermore, the present invention includes the following improvements: the top of the isolation box has multiple ventilation holes, an annular frame is provided inside the ventilation holes, a dustproof and breathable mesh is provided inside the annular frame, and the annular frame is threadedly connected to the ventilation holes; an annular limiting frame is provided at the top of the ventilation holes at the upper end of the isolation box.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, the present invention provides an isolation device for FPC circuit board processing, which has the following beneficial effects:

[0014] Automated timing and precise control:

[0015] The timer is linked with the lifting component to realize automatic control of electroplating time, avoid errors from manual monitoring, improve the uniformity of plating thickness, solve the problem of "insufficient time or over-plating" in traditional manual operation, and reduce material waste and defect rate.

[0016] The cylinder-driven lifting assembly operates smoothly, and the immersion and removal speed of the blank is controllable, which can prevent the plating solution from splashing and ensure that the blank remains vertical in the plating solution, thus avoiding uneven plating thickness.

[0017] Flexible clamping and adaptability:

[0018] The design of the top block sliding along the guide rod and the angle adjustment can adapt to FPC blanks of different sizes (length, width). The position is locked by the first locking rod to ensure clamping stability.

[0019] The threaded clamping structure of the clamping block and the second limiting plate can adjust the clamping force according to the thickness of the blank, avoiding excessive tightness that causes the blank to deform or excessive looseness that causes it to fall off. It is especially suitable for flexible circuit boards with a thickness of 0.1-1mm. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model discloses an FPC circuit board processing isolation device, including a processing table 1, an isolation box 3 at the upper end of the processing table 1, an electroplating tank 2 fixed to the upper end of the processing table 1 inside the isolation box 3, and a door at the front end of the isolation box 3. A timer 4 is provided on one side of the isolation box 3, and a lifting assembly 5 is provided at the upper end of the isolation box 3. The timer 4 and the lifting assembly 5 are connected by an electrical signal. The output end of the lifting assembly 5 is provided with a lifting rod 6 inserted into the isolation box 3. The lower end of the lifting rod 6 is provided with a bottom rod 7. Two side plates 8 are symmetrically arranged at both ends of the bottom rod 7.

[0027] The clamping assembly includes a top block 10 and a clamping block 15. A first limiting plate 12 and a second limiting plate 13 are symmetrically arranged at the lower end of the top block 10. A slot is provided between the first limiting plate 12 and the second limiting plate 13. The clamping block 15 is located inside the slot, and a second locking rod 14 is provided at the front end of the clamping block 15, which penetrates the first limiting plate 12. The second locking rod 14 is threadedly connected to the first limiting plate 12.

[0028] The lifting assembly 5 is a cylinder.

[0029] The top of the isolation box 3 has multiple ventilation holes 16, and an annular frame 17 is provided inside the ventilation hole 16. The annular frame 17 is provided inside the dustproof and breathable net 18, and the annular frame 17 is threadedly connected to the ventilation hole 16. The top of the ventilation hole 16 is provided with an annular limiting frame 19 located at the upper end of the isolation box 3.

[0030] Pretreatment and billet clamping:

[0031] The top block 10 is slidably connected to the guide rod 9. The top block 10 has a through hole through which the guide rod 9 passes. The upper end of the top block 10 is provided with a first locking rod 11. The first locking rod 11 passes through the top block 10 and its bottom end contacts the guide rod 9. The first locking rod 11 is threadedly connected to the top block 10. The cross-section of the guide rod 9 is circular.

[0032] Both the upper end of the first locking rod 11 and the outer end of the second locking rod 14 are provided with a toggle block;

[0033] Open the lock of the cabinet door. According to the size of the FPC circuit board blank, slide the top block 10 along the guide rod 9 to adjust the spacing of the clamping components. At the same time, the angle of the top block 10 on the guide rod 9 can be rotated to ensure that the blank can be placed horizontally. After adjustment, turn the first locking rod 11 to make its bottom end press tightly against the guide rod 9 to fix the position of the top block 10.

[0034] Insert the top of the rectangular sheet-shaped FPC blank into the slot between the first limiting plate 12 and the second limiting plate 13 at the lower end of the top block 10. Rotate the second locking rod 14 to push the clamping block 15 to move towards the second limiting plate 13 until the blank is tightly clamped (the operation can be simplified by using the toggle block).

[0035] Electroplating process startup:

[0036] Close and lock the box door, start the lifting assembly 5 (cylinder), the cylinder push rod drives the lifting rod 6 to move downward, and the side plates 8 descend accordingly, so that the clamped blank is immersed in the plating solution in the electroplating tank 2.

[0037] Set the electroplating time (e.g., preset 15 minutes) on the timer 4 on the side of the isolation box 3. The timer 4 is electrically connected to the lifting assembly 5 and starts timing synchronously.

[0038] Automatic retrieval and termination:

[0039] After the preset time is reached, the timer 4 sends an electrical signal to trigger the lifting component 5 to reverse its movement. The lifting rod 6 drives the billet to rise at a constant speed until it is completely removed from the plating solution and stops at the designated position in the isolation box 3.

[0040] Open the box door, loosen the second locking rod 14, take out the electroplated blank, and complete a single electroplating process.

[0041] Isolation Box 3 Maintenance:

[0042] When it is necessary to clean the dustproof and breathable mesh 18, rotate the top annular limit bracket 19 to remove the annular bracket 17 from the ventilation hole 16, then unscrew the annular bracket 17 and take out the dustproof and breathable mesh 18 for cleaning or replacement to ensure the cleanliness of the air in the isolation box 3.

[0043] The isolation box 3, with its sealed door design, reduces the entry of external dust. The dustproof and breathable mesh 18 (fixed by the threaded ring frame 17) inside the top ventilation hole 16 can filter particles in the air, maintain internal cleanliness, and meet the high environmental requirements of the electroplating process.
