Description

Technical Field

[0001] This utility model relates to the field of electronic manufacturing, and in particular to a cutting platform for cutting flexible circuit boards. Background Technology

[0002] Flexible printed circuit boards (FPCs) are crucial interconnect components in modern electronic devices, and the precision of their cutting directly impacts product reliability and yield. In laser cutting processes, the high energy of the laser beam can easily lead to material ablation and carbonization when applied directly to the surface of the FPC. Therefore, the industry commonly employs a process of covering the surface with a pure white protective film. This pure white protective film effectively reduces laser energy absorption through its high reflectivity, minimizes the heat-affected zone, and prevents spatter from contaminating the circuit board surface during cutting. Simultaneously, its high-contrast white substrate enhances the recognition accuracy of the laser positioning system, ensuring precise matching between the cutting path and the designed pattern.

[0003] Traditional protective film application processes rely heavily on manual operation. Specifically, operators must manually unfold and lay the roll of protective film flat on the cutting table surface, visually adjusting it to cover the area of ​​the flexible circuit board to be cut. During this process, uneven tension can easily cause wrinkles or misalignment of the protective film, leading to laser positioning errors. Furthermore, manual application makes it difficult to achieve rapid and accurate alignment between the protective film and the cutting table surface, especially during batch processing, requiring frequent production interruptions to replace the protective film, severely limiting processing efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: This example provides a cutting platform for cutting flexible circuit boards. See [link to example]. Figure 1-4 Specifically, the system includes a cutting table body 1, a collecting roller 11 rotatably mounted on one side of the cutting table body 1, a protective film 12 wound on the collecting roller 11, and a cutting area 13 formed on the surface of the protective film 12. A traction component 14 is mounted on one end of the cutting table body 1, and the traction component 14 is connected to the free end of the protective film 12. The traction component 14 is used to drive the protective film 12 to unfold and cover the working surface of the cutting table body 1. The cutting table body 1 is a laser cutting platform. In use, a flexible circuit board is laid on the surface of the cutting table body 1, and the protective film 12 is pulled by the traction component 14 to lay the protective film 12 on the surface of the flexible circuit board, aligning the cutting area 13 on the protective film 12 with the cutting position of the flexible circuit board. The protective film 12 effectively reduces laser energy absorption, reduces the heat-affected zone, and avoids the contamination of the circuit board surface by the spatter generated during the cutting process. The traction component 14 drives the protective film 12 to unfold and rewind quickly, improving efficiency. The traction component 14 also drives the protective film 12 to move along a designated route, improving the accuracy of the alignment between the cutting area 13 of the protective film 12 and the flexible circuit board.

[0024] In the specific implementation process, such as Figure 2 and Figure 4 As shown, the traction assembly 14 includes a linear guide rail 3 fixedly installed at the end of the cutting table body 1. A connecting plate 2 is provided on the slider 34 of the linear guide rail 3. The connecting plate 2 is fixedly connected to the free end of the protective film 12. The linear guide rail 3 is used to drive the connecting plate 2 to move linearly back and forth. The length of the connecting plate 2 is the same as the width of the free end of the protective film 12, and it is used to pull the protective film 12 to unfold.

[0025] In the specific implementation process, such as Figure 2 and Figure 4As shown, the linear guide 3 includes a track 31, a lead screw 32, and a motor 33. The track 31 is fixedly connected to the end of the cutting table body 1. The lead screw 32 is rotatably installed inside the track 31. The motor 33 is fixedly installed at the end of the track 31. The output end of the motor 33 is fixedly connected to the end of the lead screw 32. The lead screw 32 is threadedly connected to the slider 34. The motor 33 drives the lead screw 32 to rotate, and the lead screw 32 drives the slider 34 in the track 31 to move laterally. The slider 34 then drives the connecting plate 2 to move, and the connecting plate 2 pulls the protective film 12 to unfold.

[0026] In the specific implementation process, such as Figure 3 and Figure 4 As shown, a mounting base 4 is fixedly provided on one side of the outer wall of the cutting table body 1. The shaft of the collecting roller 11 is rotatably mounted in the middle of the mounting base 4, and the shaft of the collecting roller 11 passes through the mounting base 4. The mounting base 4 is used to limit the collecting roller 11. The collecting roller 11 is used to roll up the unfolded protective film 12.

[0027] In the specific implementation process, such as Figure 2 and Figure 3 As shown, a protective shell 5 is fixedly provided on the outside of the mounting base 4, and a coil spring 51 is fixedly provided inside the protective shell 5. The middle part of the coil spring 51 is fixedly connected to the shaft of the collecting roller 11. Coil springs 51 are provided on the shafts at both ends of the collecting roller 11. When the traction component 14 drives the protective film 12 to unfold, the collecting roller 11 rotates along the mounting base 4, and the two ends of the collecting roller 11 drive the coil springs 51 to unfold. When the traction component 14 drives the protective film 12 to move towards the collecting roller 11, the coil springs 51 reset, allowing the collecting roller 11 to reverse, thereby realizing the rapid winding of the protective film 12.

[0028] In the specific implementation process, such as Figure 1 and Figure 4 As shown, a mounting bracket 6 is fixedly provided on the inner side of the mounting base 4. A cleaning brush 61 is provided between the mounting brackets 6. The cleaning brush 61 is attached to the protective film 12. The end of the cleaning brush 61 is flexible and is attached to the outer wall of the protective film 12. The cleaning brush 61 is installed below the collecting roller 11. The protective film 12 will come into contact with the cleaning brush 61 when it is unfolded or rolled up. When it is rolled up, the cleaning brush 61 can sweep off some impurities on the protective film 12, thereby improving the uniformity of the contact surface between the protective film 12 and the circuit board.

[0029] In the specific implementation process, such as Figure 1 and Figure 2 As shown, a guide rod 7 is fixedly provided on the edge of the upper surface of the cutting table body 1. The guide rod 7 is located on the upper surface of the protective film 12. The guide rod 7 limits the protective film 12, so that the protective film 12 on the cutting table body 1 is parallel to the cutting table body 1, which facilitates the alignment of the protective film 12 with the flexible circuit board.
