Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, and specifically relates to a product shape cutting device and cutting method. Background Technology

[0002] Laser cutting uses a high-power-density laser beam to irradiate the material being cut, quickly heating it to its vaporization temperature and causing it to evaporate and form holes. As the beam moves across the material, the holes continuously form narrow kerfs, completing the cutting of the material.

[0003] In the industrial processing of flexible circuit boards, the limitations of ordinary punching (mechanical punching) can no longer meet the needs. Laser cutting offers high-quality cuts, high precision, small dimensional errors, and high flexibility. It can cut any complex shape through programming and has wide material adaptability, stably cutting both metals and non-metals, as well as high-hardness materials. Compared with laser cutting, it has significant advantages. However, due to the heat-affected zone of laser cutting, for extremely sensitive materials, such as LCP, local high temperatures can leave carbon powder on the cut surface of the flexible circuit board. At the same time, after laser cutting, the waste material separated from the flexible circuit board needs to be manually removed from the stencil by the operator, which is not conducive to the processing efficiency of flexible circuit boards. To address the above problems, how to design a product shape cutting equipment and cutting method has become a problem that we need to solve. Summary of the Invention

[0006] In the above technical solution, the limiting component further includes multiple suction cups inserted into the mesh plate, each suction cup abutting against the bottom of the flexible circuit board, and a connecting tube fixedly connected to the bottom of the multiple suction cups. A round tube is fixedly connected to one end of the connecting tube, and a first spring is fixedly installed inside the round tube. A piston is fixedly installed at one end of the first spring.

[0007] In the above technical solution, a sliding sleeve is fixedly installed at the end of the piston away from the first spring. The first spring and the sliding sleeve are slidably connected inside the circular tube. A first air hole is opened inside the sliding sleeve, and a second air hole is opened inside the circular tube. A connecting block is fixedly installed on the outer wall of the circular tube, and the connecting block is fixedly installed at the bottom of the mesh plate.

[0008] In the above technical solution, a gear sleeve is fixedly connected to the end of the round tube away from the connecting tube. The gear sleeve is rotatably connected to the inside of the support frame. A connector is rotatably connected to the end of the gear sleeve away from the round tube. A flexible tube is fixedly connected to the outer wall of the connector. The flexible tube passes through the sliding member and is fixedly connected to the laser cutting head.

[0009] In the above technical solution, the unloading assembly further includes a toothed plate meshing with the outer wall of the gear sleeve, the toothed plate being slidably connected to the inner wall of the support frame, a second spring being fixedly installed on one side of the toothed plate, a support block being fixedly installed at the end of the second spring away from the toothed plate, the support block being fixedly installed inside the support frame, and a connecting rod being slidably connected inside the support block.

[0010] In the above technical solution, a square rod is slidably connected inside the connecting rod, and triangular blocks are fixedly connected to both ends of the square rod. An elastic piece is fixedly connected to one side of the square rod, and the elastic piece abuts against the inside of the connecting rod. A third spring is fixedly installed on the side of the support block away from the second spring.

[0011] In the above technical solution, the third spring is further sleeved on the outer wall of the connecting rod, a wing is fixedly installed on the outer wall of the connecting rod, the wing is fixedly installed on one end of the third spring, a push rod is fixedly connected to the end of the connecting rod away from the toothed plate, the push rod is slidably connected to the outer wall of the first slide rail, and the first slide rail is arranged on one side of the second slide rail.

[0012] In the above technical solution, the support frame is further provided with a collection box inside, the top of the mesh plate is provided with multiple guide members, the multiple guide members abut against the outer wall of the flexible circuit board, the bottom of the multiple guide members is fixedly connected with a circular piece, the circular piece is inserted into the inside of the mesh plate, the end of the circular piece away from the guide member is fixedly connected with a threaded rod, the outer wall of the threaded rod is connected with a threaded sleeve, and the threaded sleeve abuts against the outer wall of the mesh plate.

[0013] A cutting method for a product shape cutting device includes the following steps: S1. The flexible circuit board is fixed to the mesh plate by a limiting component; S2. Two cutting lines are set in the cutting equipment by program: the inner line is the edge of the effective area of ​​the product, and the outer line is the edge of the inner line that is away from the effective area of ​​the product. S3. Using cutting equipment, the laser cutting head is controlled to cut grooves along the outer and inner lines on the flexible circuit board in sequence to form the product; S4. After the product is cut, the cutting equipment controls the restoration of each component, and the unloading assembly collects the waste material cut from the flexible circuit board.

[0014] In the above technical solution, further, in step S3, when the laser cutting head cuts the flexible circuit board along the inner line, half of the laser of the laser cutting head cuts the flexible circuit board along the inner line, and the other half passes through the groove formed by the outer line cutting, without contacting the flexible circuit board, thus forming a product with less carbon powder; at the same time, the coaxial nozzle on the laser cutting head is controlled to spray gas to blow away the carbon powder remaining on the flexible circuit board after cutting along the inner line through the groove formed by the outer line cutting, ensuring that no carbon powder remains on the side wall of the product.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By setting up a material unloading component, the flexible circuit board can be cut on the screen and the product can be formed.

This eliminates the need for workers to manually remove the waste material cut off from the screen one by one, reducing the labor intensity of workers and improving the production efficiency of the product. By setting limit components, workers can quickly position and fix flexible circuit boards on the mesh, making it easier for workers to place the flexible circuit boards and thus improving the cutting efficiency of the flexible circuit boards.

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1 to 7 The product shape cutting equipment and cutting method shown includes a support frame 1, with first slide rails 2 symmetrically installed on the top of the support frame 1. Linear motors 3 are slidably connected to the top of each of the two first slide rails 2. Second slide rails 4 are fixedly installed on the top of each of the two linear motors 3. Sliding elements 5 are slidably connected to the top of the second slide rails 4. A laser cutting head 6 is fixedly installed at the bottom of the sliding elements 5. A flexible circuit board 8 and a mesh plate 7 are arranged sequentially from top to bottom at the bottom of the laser cutting head 6. A limiting component is used to assist the operator in positioning and fixing the flexible circuit board 8. The limiting component is connected to the support frame 1, the sliding elements 5, the laser cutting head 6, the mesh plate 7, and the flexible circuit board 8. An unloading component is used to assist the operator in unloading and collecting the waste material after laser cutting. The unloading component is connected to the support frame 1, the first slide rails 2, the second slide rails 4, and the limiting component.

[0020] The limiting component includes multiple suction cups 9 inserted inside the mesh plate 7. Each suction cup 9 rests against the bottom of the flexible circuit board 8 (the suction cups 9 are located at the bottom of the effective area of ​​the flexible circuit board 8). A connecting tube 10 is fixedly connected to the bottom of each suction cup 9. A round tube 11 is fixedly connected to one end of the connecting tube 10. A first spring 12 is fixedly installed inside the round tube 11. A piston 13 is fixedly installed to one end of the first spring 12. A sliding sleeve 14 is fixedly installed to the end of the piston 13 away from the first spring 12. The first spring 12 and the sliding sleeve 14 are slidably connected inside the round tube 11. A first air hole 15 is opened inside the sliding sleeve 14, and a second air hole 16 is opened inside the round tube 11. A connecting block 17 is fixedly installed on the outer wall of the round tube 11. The connecting block 17 is fixedly installed at the bottom of the mesh plate 7. The round tube 11 is located away from the connecting... One end of the tube 10 is fixedly connected to a gear sleeve 18, which is rotatably connected inside the support frame 1. The end of the gear sleeve 18 away from the round tube 11 is rotatably connected to a connector 19. A hose 20 is fixedly connected to the outer wall of the connector 19. An air pump (unlabeled) is fixedly connected to the outer wall of the hose 20. The hose 20 passes through the sliding member 5 and is fixedly connected to the laser cutting head 6. A collection box 31 is provided inside the support frame 1. Multiple guide members 32 are provided on the top of the mesh plate 7. The multiple guide members 32 abut against the outer wall of the flexible circuit board 8. A circular piece 33 is fixedly connected to the bottom of the multiple guide members 32. The circular piece 33 is inserted into the inside of the mesh plate 7. A threaded rod 34 is fixedly connected to the end of the circular piece 33 away from the guide member 32. A threaded sleeve 35 is connected to the outer wall of the threaded rod 34 by threads. The threaded sleeve 35 abuts against the outer wall of the mesh plate 7. The limiting component is used to position and fix the flexible circuit board 8. After the operator positions the flexible circuit board 8 on top of the mesh board 7 using the guide limiter 32, the operator can start the cutting equipment. The cutting equipment will work according to the set program, causing the air pump on the outer wall of the hose 20 to work. This causes the sliding component 5 to move the laser cutting head 6 to the starting point on the flexible circuit board 8 that needs to be cut. The air pump on the outer wall of the hose 20 will draw gas from the inside of the connector 19 and discharge it into the inside of the laser cutting head 6. This allows the laser cutting head 6 to blow away the carbon powder and other molten materials generated by the high temperature during laser cutting when cutting the flexible circuit board 8, thus protecting the cut quality and preventing a large amount of carbon powder residue from remaining at the cut. During the process of the hose 20 drawing gas through the connector 19, the connector 19 will draw gas from the inside of the round tube 11 through the gear sleeve 18. The gas causes the piston 13 and sliding sleeve 14 inside the circular tube 11 to be attracted by negative pressure, sliding towards the gear sleeve 18 and pulling the first spring 12 to extend until the first air hole 15 on the sliding sleeve 14 coincides with the second air hole 16 on the circular tube 11. The gas then enters the interior of the circular tube 11 through the second air hole 16 and the first air hole 15 and is drawn away. Finally, it is discharged into the interior of the laser cutting head 6 through the hose 20 and ejected. The piston 13 moves towards the gear sleeve 18 and draws the gas inside the connecting tube 10, causing the suction cup 9 connected to the connecting tube 10 to attract the flexible circuit board 8 on the mesh plate 7. The flexible circuit board 8 is fixed on the top of the mesh plate 7, so as to facilitate the positioning and fixing of the flexible circuit board 8 by the staff, thereby improving the cutting efficiency of the flexible circuit board 8.

[0021] The unloading assembly includes a toothed plate 21 meshing with the outer wall of the gear sleeve 18. The toothed plate 21 is slidably connected to the inner wall of the support frame 1. A second spring 22 is fixedly installed on one side of the toothed plate 21. A support block 23 is fixedly installed at the end of the second spring 22 away from the toothed plate 21. The support block 23 is fixedly installed inside the support frame 1. A connecting rod 24 is slidably connected inside the support block 23. A square rod 25 is slidably connected inside the connecting rod 24. Triangular locking blocks 26 are fixedly connected to both ends of the square rod 25. An elastic plate 2 is fixedly connected to one side of the square rod 25. 7. The elastic piece 27 abuts against the inside of the connecting rod 24. The elastic piece 27 is used to push the square rod 25 to reset. The support block 23 is fixedly installed with a third spring 28 on the side away from the second spring 22. The third spring 28 is sleeved on the outer wall of the connecting rod 24. The outer wall of the connecting rod 24 is fixedly installed with a wing piece 29. The wing piece 29 is fixedly installed on one end of the third spring 28. The end of the connecting rod 24 away from the toothed plate 21 is fixedly connected with a push rod 30. The push rod 30 is slidably connected to the outer wall of the first slide rail 2. The first slide rail 2 is located on one side of the second slide rail 4. The unloading assembly is used to collect the waste material cut from the flexible circuit board 8. When the flexible circuit board 8 is cut, during the process of the components of the cutting equipment returning to their original positions, the second slide rail 4 pushes the push rod 30, causing the push rod 30 to slide along the outer wall of the first slide rail 2 and pull the connecting rod 24 to slide along the inside of the support block 23. The connecting rod 24 pulls the third spring 28 to extend through the wing 29, and pulls the toothed plate 21 to move through one of the triangular blocks 26 on the square rod 25. The movement of the toothed plate 21 will compress the second spring 22 to contract and drive the gear sleeve 18 to rotate. The rotation of the gear sleeve 18 will drive the mesh plate 7 to rotate through the round tube 11 and the connecting block 17. The mesh plate 7 will drive the flexible circuit board 8 cut at the top to rotate together, so that the cut waste material on the mesh plate 7 that is not held by the suction cup 9 falls into the inside of the collection box 31. After 7 is rotated 180 degrees, another triangular block 26 on the connecting rod 24 is pulled into the support block 23, causing the support block 23 to press the triangular block 26 into the connecting rod 24. This causes the square rod 25 to deform the elastic sheet 27 and stop connecting with the toothed plate 21 through the triangular block 26. This allows the second spring 22 to push the toothed plate 21 to slide back to its original position, which in turn causes the toothed plate 21 to drive the gear sleeve 18 to rotate back to its original position. The gear sleeve 18 then drives the mesh plate 7 to rotate back to its original position through the round tube 11 and the connecting block 17. At this time, only the cut products adsorbed by the suction cup 9 remain on the mesh plate 7, achieving the effect of quickly collecting the waste material cut off from the flexible circuit board 8. This eliminates the need for workers to manually remove the waste material cut off from the flexible circuit board 8 one by one from the mesh plate 7, reducing the labor intensity of workers and improving the production efficiency of the products. It should be noted that the air pump on the outer wall of the hose 20 needs to stop working after the linear motor 3, the second slide rail 4, the sliding part 5, the laser cutting head 6 and other components return to their origin, so that the piston 13 and the sliding sleeve 14 inside the round tube 11 lose the negative pressure adsorption, and then the first spring 12 pulls the piston 13 and the sliding sleeve 14 to reset, and the gas drawn from the inside of the connecting tube 10 is discharged back, so that the suction cup 9 stops adsorbing and fixing the product formed by cutting the flexible circuit board 8, making it convenient for the staff to remove it; It should be noted that when the cutting equipment operates again, after the second slide rail 4 stops pressing the push rod 30, the third spring 28 will push the connecting rod 24 to reset via the wing 29. This causes the connecting rod 24 to drive the push rod 30 to reset and move the square rod 25 toward the toothed plate 21. The movement continues until the connecting rod 24, through the square rod 25, causes the triangular locking block 26 to disengage from the inside of the support block 23 and another triangular locking block 26 to re-engage into the inside of the toothed plate 21. At this point, the toothed plate 21 and the connecting rod 24 are reconnected through the square rod 25 and the triangular locking block 26, ready for the next operation.

[0022] A cutting method for a product shape cutting device includes the following steps: S1. The flexible circuit board 8 is fixed onto the mesh plate 7 using a limiting component; S2. Two cutting lines are set in the cutting equipment by program: the inner line is the edge of the effective area of ​​the product, and the outer line is the edge of the inner line that is away from the effective area of ​​the product. S3. Using a cutting device, the laser cutting head 6 is controlled to cut grooves along the outer and inner lines on the flexible circuit board 8 in sequence to form a product; S4. After the product is cut, the cutting equipment controls the restoration of each component, and the unloading assembly collects the waste material cut from the flexible circuit board 8.

[0023] In step S3, when the laser cutting head 6 cuts the flexible circuit board 8 along the inner line, half of the laser from the laser cutting head 6 cuts the flexible circuit board 8 along the inner line, while the other half passes through the groove formed by the outer line cutting, without contacting the flexible circuit board 8, resulting in a product with less toner. At the same time, the coaxial nozzle on the laser cutting head 6 is controlled to spray gas to blow away the toner residue left by the inner line cutting of the flexible circuit board 8 through the groove formed by the outer line cutting, ensuring that no toner residue remains on the side wall of the product.

[0024] Working principle: The flexible circuit board 8 is fixed to the stencil 7 by a limiting component. The cutting equipment is controlled to work according to two pre-set cutting lines with an interval of 10-20µm, causing the laser cutting head 6 to sequentially cut 30µm grooves along the outer and inner lines (e.g., ...). Figure 7 As shown in the diagram (from left to right: outer line cutting schematic, inner line cutting schematic, and the completed groove schematic), after the laser cutting head 6 cuts the flexible circuit board 8 along the outer line, the product outline is formed. Then, cutting continues along the inner line. At this time, half of the laser from the laser cutting head 6 falls in the groove formed by the outer line cutting, and the other half falls on the outer outline of the product formed by the flexible circuit board 8. The gas ejected by the laser cutting head 6 can blow away the carbon powder generated during the inner line cutting and discharge it from the groove formed by the outer line cutting, reducing residual carbon after the product is cut and preventing the flexible circuit board 8 from being cut without being penetrated by the laser. The carbon powder generated during laser cutting accumulates inside the grooves cut into the flexible circuit board 8. This causes the carbon powder to adhere to the inside of the grooves after the laser penetrates the flexible circuit board 8, making it impossible to be blown away by the gas. To solve the problem of carbon powder on the sidewalls of the laser cutting and improve product yield, the post-laser cleaning process can be eliminated, saving production costs. After the product is cut, the cutting equipment controls the restoration of each component, so that the unloading component collects the waste material cut from the flexible circuit board 8. Then, the workers can remove the finished product from the flexible circuit board 8 and replace it with a new flexible circuit board 8 for cutting.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
