Description

An FFC flat line laser engraving device Technical Field

[0001] This utility model relates to the field of FFC flat wire, specifically to an FFC flat wire laser engraving device. Background Technology

[0002] FFC (Flexible Flat Cable) is a type of cable with a flat structure. FFC laser engraving equipment is a specialized device used to laser-engrave markings on the surface of FFC. It combines laser technology with precision mechanical design, enabling the engraving of high-precision, high-definition text, patterns, logos, or QR codes on the insulation or conductor surface of FFC flat cables.

[0003] In the traditional FFC flat line laser engraving process, the surface cleanliness directly affects the engraving quality and product yield. However, existing FFC flat line laser engraving equipment lacks a cleaning mechanism, which inevitably leads to dust or impurities adhering to the surface during the transport of the FFC flat line. This dust or impurities can block the laser beam, resulting in uneven energy distribution in the engraving area and forming "broken lines" or "ghost images".

[0004] Therefore, it is necessary to invent an FFC flat line laser engraving device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an FFC flat wire laser engraving device. When the FFC flat wire being transported passes under the soft brush head first, the servo motor switch is turned on, driving the first lead screw to rotate. The rotation of the first lead screw drives the external moving seat and the soft brush head below to move left and right, thereby cleaning the surface of the FFC flat wire and preventing dust from remaining on the surface. At this time, the air pump switch on the back of the laser engraving worktable is turned on, and the dust swept down is absorbed by the suction pipe and suction hood. At the same time, the suction pipe and suction hood on the other side are located behind the laser engraving, so that the surface residue is absorbed after the laser engraving. This solves the problem mentioned in the background art that the surface cleanliness of traditional FFC flat wires directly affects the engraving quality and product yield during the laser engraving process. However, existing FFC flat wire laser engraving devices lack a cleaning mechanism, which inevitably leads to dust or impurities sticking to the surface when transporting the FFC flat wire. This dust or impurities can block the laser beam, resulting in uneven energy distribution in the engraving area and forming problems such as "broken lines" or "ghost images".

[0006] To achieve the above objectives, this utility model provides the following technical solution: an FFC flat line laser engraving device, including a laser engraving worktable for FFC flat line laser engraving;

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides an FFC flat line laser engraving equipment as shown in Figures 1-5, including a laser engraving worktable 1 for FFC flat line laser engraving;

[0028] Rotary rod 2 is rotatably connected to the front side of laser engraving workbench 1 and is used to limit the conveying of FFC flat line. A cleaning mechanism 5 is fixedly installed on the upper side of laser engraving workbench 1. The cleaning mechanism 5 includes a fixed frame 501, which is fixed on the upper side of laser engraving workbench 1. A servo motor 502 is fixedly installed on the rear side of the fixed frame 501. A first lead screw 503 is fixedly connected to the output end of the servo motor 502. A movable seat 504 is connected to the external thread of the first lead screw 503. Telescopic rods 505 pass through both sides of the movable seat 504. A fixed seat 506 is fixedly connected to the lower end of the telescopic rod 505. A soft brush head 508 is fixedly installed at the lower end of the fixed seat 506.

[0029] The second pressure roller 8 is rotatably connected above the laser engraving worktable 1 for compaction and conveying. A fixed bracket 9 is fixedly connected above the laser engraving worktable 1. A drive motor 10 is fixedly installed on one side of the fixed bracket 9. A second lead screw 11 is fixedly connected to the output end of the drive motor 10. A movable frame 12 is threadedly connected to the outside of the second lead screw 11. A laser engraving assembly 13 is fixedly connected inside the movable frame 12. A vision camera 14 is fixedly connected to the rear side of the fixed bracket 9.

[0030] A dust collection assembly 15, installed on the rear side of the laser engraving workbench 1, is used for dust collection. The dust collection assembly 15 includes a dust collection box 1501, with an air pump 1502 fixedly mounted above the dust collection box 1501. Dust collection pipes 1503 are fixedly connected to both sides of the dust collection box 1501, and a dust collection hood 1504 is fixedly connected to the other end of each dust collection pipe 1503. When the FFC flat cable being transported passes under the soft brush head 508, the servo motor 502 is turned on, causing the first lead screw 503 to rotate. The first lead screw 503 rotates, causing the external movable seat 504 and the lower soft brush head 508 to move left and right, thereby cleaning the surface of the FFC flat line and preventing dust from remaining on the surface of the FFC flat line. At this time, the air pump 1502 switch on the back of the laser engraving workbench 1 is turned on, and the dust swept down is sucked away through the suction pipe 1503 and the suction hood 1504. At the same time, the suction pipe 1503 and the suction hood 1504 on the other side are located behind the laser engraving, so that the surface residue is sucked away after the laser engraving.

[0031] As shown in Figure 1, the external of the rotating rod 2 is fixedly connected to the limiting plate 3. The front side of the laser engraving worktable 1 is rotatably connected to the first pressure roller 4. Through the limiting plate 3 outside the rotating rod 2, the FFC flat line can be limited and conveyed to avoid deviation. Then, it is compacted and conveyed by the first pressure roller 4.

[0032] As shown in Figure 2, the telescopic rod 505 is symmetrically arranged with respect to the central axis of the movable seat 504. A spring 507 is sleeved on the outside of the telescopic rod 505. The spring 507 is located between the movable seat 504 and the fixed seat 506. The spring 507 on the outside of the telescopic rod 505 rebounds and presses the fixed seat 506 and the soft brush head 508, so that the soft brush head 508 can stick to the surface of the FFC flat line to clean the dust.

[0033] As shown in Figure 1, screws 6 are threaded through both sides of the upper part of the laser engraving worktable 1. The lower end of the screws 6 is rotatably connected to a movable seat 7. The second pressure roller 8 is rotatably connected to the movable seat 7. By rotating the screws 6 on both sides of the upper part of the laser engraving worktable 1, the movable seat 7 and the second pressure roller 8 are pushed to adjust the height, thereby pressing the FFC flat line again before laser engraving to avoid the situation of lifting up and affecting the laser engraving effect.

[0034] As shown in Figures 1 and 4, the dust collection hood 1504 is fixed on the front and rear sides of the laser engraving worktable 1. One dust collection hood 1504 is located on one side of the cleaning mechanism 5, and the other dust collection hood 1504 is located below the vision camera 14. The first dust collection hood 1504 can adsorb dust when the cleaning mechanism 5 cleans the surface of the FFC flat line, while the second dust collection hood 1504 can adsorb the residue after laser engraving when inspecting the FFC flat line. This adsorbs the residue after laser engraving and keeps the surface clean.

[0035] As shown in Figures 1 and 5, a fixed plate 16 is fixedly connected to the rear side of the laser engraving worktable 1. Two sets of traction rollers 17 are rotatably connected inside the fixed plate 16. An electric push rod 18 is fixedly installed on the rear side of the fixed plate 16. A connecting seat 19 is fixedly connected to the output end of the electric push rod 18. The connecting seat 19 slides with the fixed plate 16. A tension roller 20 is rotatably connected inside the connecting seat 19. The two sets of traction rollers 17 facilitate the traction and winding of the FFC flat line. At the same time, the electric push rod 18 pushes the connecting seat 19 and the tension roller 20 to rise and fall, which can enhance the tension during the conveying process of the FFC flat line.

[0036] The working principle of this utility model is as follows: First, connect the external power supply. Then, the FFC flat wire is wound between the rotating rod 2 and the limiting plate 3 on the front side of the laser engraving worktable 1 for limited conveying. After that, the FFC flat wire enters the lower side of the first pressure roller 4 for compaction and conveying. Then, it enters the area below the soft brush head 508. By turning on the switch of the servo motor 502 on the outside of the fixed bracket 501, the first lead screw 503 is driven to rotate. The rotation of the first lead screw 503 drives the external moving seat 504 and the soft brush head 508 below to move left and right, thereby cleaning the surface of the FFC flat wire. After cleaning the surface dust, turn on the switch of the air pump 1502 on the rear side of the laser engraving worktable 1. The dust swept up is absorbed by the dust suction pipe 1503 and the dust suction hood 1504. Then, the cleaned FFC flat wire is conveyed from under the second pressure roller 8 into the area below the laser engraving assembly 13. By turning on the switch of the drive motor 10 on the rear side of the fixed bracket 9, the second pressure roller 8 is driven to rotate. The lead screw 11 rotates, and the rotation of the second lead screw 11 drives the moving frame 12 to move left and right, performing laser engraving on the surface of the FFC flat line. When the laser-engraved FFC flat line is transported to the vision camera 14 behind the laser engraving assembly 13, it is inspected by the vision camera 14. At this time, another dust suction hood 1504 is aligned with the FFC flat line under the laser engraving area below the vision camera 14, and the surface of the FFC flat line is suctioned again. After inspection, the FFC flat line enters the two sets of traction rollers 17 on the rear side for traction and transport. In order to increase the tension of the FFC flat line, the electric push rod 18 switch on the rear side of the fixed plate 16 is turned on, which pushes the connecting seat 19 and the tension roller 20 to rise and fall, adjusting the tension of the FFC flat line wound on the tension roller 20. Finally, the laser-engraved FFC flat line is wound up, and the use of the FFC flat line laser engraving equipment is completed.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
