Description

Technical Field

[0001] This invention relates to the field of laser cutting technology for FPC flexible circuit boards, and in particular to a laser cutting device and method for FPC flexible circuit boards used in new energy batteries. Background Technology

[0002] Flexible printed circuit boards (FPCs) are important components widely used in electronic devices, favored for their thinness, flexibility, and foldability. The manufacturing process of FPCs requires laser cutting of the FPC rolls.

[0003] Utility model publication CN208178726U discloses an FPC laser cutting device, including a cutting assembly and a fixing assembly. The cutting assembly includes a base, a motor, a roller, a belt, a laser head, a conveyor belt, a crossbar, and a slide bar. The base is fixedly connected to the motor, which is located above the base. The motor is connected to the roller via the belt drive. The FPC is placed on the conveyor belt, which moves the FPC to the left above the support. A fan draws air out of the support through the air duct. However, during FPC roll cutting, not only is there waste material outside the finished product frame, but also cutting waste. Since the frame waste and cutting waste have different physical properties, they need to be collected and processed separately. The aforementioned FPC laser cutting device is inconvenient for separating and processing the finished product, frame waste, and cutting waste generated after laser cutting. Therefore, this solution proposes a laser cutting device and method for flexible circuit boards (FPCs) used in new energy batteries to solve the above problems. Summary of the Invention

[0004] In view of this, the present invention proposes a laser cutting device and method for flexible printed circuit boards (FPCs) used in new energy batteries. By setting a material-grabbing mechanism that moves between the processing station, the finished product station, and the first waste collection port, the material-grabbing mechanism can grab the finished products and outer frame waste generated during cutting and supply them to the processing station and the first waste collection port respectively, thereby completing the independent recycling of the finished products and outer frame waste. By setting the material-grabbing mechanism to pass through a partition placement station during its movement, the material-grabbing mechanism can also grab the partition and place it on the finished products to mutually block each finished product, facilitating the collection of multiple finished products at once at the finished product station. By setting an ion air knife to blow away the cutting waste, the air-blowing and collection effect of the cutting waste is improved. By setting the ion air knife to move along the length of the processing table, it is convenient to blow all the cutting waste on the entire processing station to the second waste collection port for collection after processing by adjusting the movement of the ion air knife, making it convenient to use.

[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0051] like Figures 1-6As shown, the laser cutting device for flexible printed circuit boards (FPCs) for new energy batteries of the present invention is characterized by comprising a processing table 1, a processing station 21, a finished product station 22, a partition placement station 23, a feeding conveyor 31, an unloading conveyor 32, a laser processing mechanism 4, and a material gripping mechanism 5. The processing station 21, the finished product station 22, and the partition placement station 23 are all arranged on the processing table 1 and are distributed sequentially along the width of the processing table 1. The processing station 21 is used to support the FPC roll 10, the finished product station 22 is used to support the cut finished product, and the partition placement station 23 is used to support the partition. The processing table 1 has a first waste collection port 24 and a second waste collection port 25. The first waste collection port 24 is located on the side of the partition placement station 23 away from the finished product station 22 and is used to store outer frame waste. The second waste collection port 25... The inlet 25 is located on the side of the processing station 21 away from the feeding conveyor 31 along the length of the processing station 21, and is used to store cutting waste. The feeding conveyor 31 and the discharging conveyor 32 are respectively arranged at both ends of the processing station 21 along the length of the processing station 21, and are both used to convey the FPC roll 10 along the length of the processing station 21. The laser processing mechanism 4 includes a laser 41 and an ion air knife 42. The laser 41 is used to cut the FPC roll 10 on the processing station 21, and the ion air knife 42 moves along the length of the processing station 21 to blow the cutting waste on the processing station 21 to the second waste collection inlet 25. The material gripping mechanism 5 moves between the processing station 21, the finished product station 22, the partition placement station 23 and the first waste collection inlet 24 to pick up FPC material or partitions.

[0052] Figure 1 In the middle, the X direction is the length direction of the machining table 1, the Y direction is the width direction of the machining table 1, and the Z direction is the height direction of the machining table 1.

[0053] In specific implementation, the FPC roll 10 is conveyed by the feeding conveyor 31 and the discharging conveyor 32 to move along the length of the processing table 1. When the FPC roll 10 covers the processing station 21, the laser processing mechanism 4 completes the laser processing of the FPC roll 10 on the processing station 21. After the laser processing is completed, the cut finished product is generated. The material grabbing mechanism 5 grabs the cut finished product and the outer frame waste at the same time and supplies them to the finished product station 22 and the first waste collection port 24 respectively, thereby completing the collection and processing of the cut finished product and the outer frame waste. Then, by adjusting the ion air knife 42 to move along the length of the processing table 1, the cut waste on the processing station 21 is blown into the interior of the second waste collection port 25, thereby completing the collection and processing of the cut waste.

[0054] By setting the material-grabbing mechanism 5 to move between the processing station 21, the finished product station 22, and the first waste collection port 24, the material-grabbing mechanism 5 can grab the finished products and outer frame waste generated during cutting and supply them to the processing station 21 and the first waste collection port 24 respectively, thereby completing the independent recycling of the finished products and outer frame waste. By setting the material-grabbing mechanism 5 to pass through the partition placement station 23 during its movement, the material-grabbing mechanism 5 can also grab the partition and place it on the finished products to mutually block each finished product, making it convenient for the finished product station 22 to collect multiple finished products at once. By setting the ion air knife 42 to blow the cutting waste, the air-blowing and collection effect of the cutting waste is improved. By setting the ion air knife 42 to move along the length of the processing table 1, it is convenient to blow all the cutting waste on the processing station 21 to the second waste collection port 25 for collection after processing by adjusting the movement of the ion air knife 42, which is convenient to use.

[0055] Preferably, the processing station 21 is provided with a wind adsorption component for adsorbing the FPC roll 10 toward the table surface of the processing station 21, so that the FPC roll 10 is tightly attached to the table surface of the processing station 21, which facilitates subsequent laser cutting processing.

[0056] Preferably, the laser 41 in this application is an ultraviolet picosecond laser with a power of 30W or 15W and a wavelength of less than or equal to 355nm.

[0057] This design, with its shorter wavelength, allows for higher beam focusing, resulting in greater cutting precision and suitability for processing fine structures. The picosecond laser's extremely short pulse width (picosecond level) generates very little heat during cutting, reducing the heat-affected zone and thus minimizing material thermal deformation and damage. If the laser 41's power is below 15W, it cannot meet the cutting requirements of FPC rolls, leading to slow cutting speeds, poor cutting quality, or even the inability to cut FPC rolls. If the laser 41's power is between 30W and below, the FPC roll material will overheat during cutting, creating a large heat-affected zone, causing problems such as roll deformation, scorching, or rough cut edges.

[0058] Preferably, the processing table 1 in this application is a marble table.

[0059] In a preferred embodiment, both the feeding conveyor 31 and the discharging conveyor 32 are used to convey two FPC rolls 10. The number of processing stations 21, finished product stations 22, partition placement stations 23 and the first waste collection port 24 are all two, and they are symmetrically distributed in the width direction of the processing table 1.

[0060] This design gives the processing table 1 of this application two workstations, one on the left and one on the right, which are symmetrically distributed relative to the processing table 1. In practice, the two workstations on the processing table 1 simultaneously perform cutting and material collection of two FPC rolls 10, thereby increasing the efficiency of laser processing of the FPC rolls 10.

[0061] In a preferred embodiment, the laser processing mechanism 4 also includes a positioning camera 43, which is equipped with a CCD vision positioning system. The positioning camera 43 is used to visually inspect the FPC roll 10 on the processing station 21.

[0062] By including a positioning camera 43 in the laser processing mechanism 4, the laser 41 can identify and position the Mark mark on the FPC roll 10 in advance through the CCD vision positioning system on the positioning camera 43 when processing the FPC roll 10, thereby positioning the laser 41 at the position to be cut, so as to complete the accurate cutting of the FPC roll 10 and make it convenient to use.

[0063] Preferably, the positioning camera 43 has 5 megapixels, a field of view of ≥4mm*6mm, an alignment accuracy of ≤±5μm, and an LED light source.

[0064] This design allows the 5-megapixel camera to provide clear images, ensuring detailed capture, which is crucial for accurately locating and identifying small features such as FPC flexible circuit boards. The LED light source, with its high brightness, low power consumption, and long lifespan, provides stable illumination, reduces shadows and reflections, and improves image quality. Furthermore, the spectral range of the LED light source can be adjusted as needed to suit different reflective characteristics.

[0065] In a preferred embodiment, the laser processing mechanism 4 further includes a first slide rail 61, a first sliding base 44, a second sliding base 45, and a lifting cylinder 46. The first slide rail 61 is disposed on the processing table 1 and extends along the length of the processing table 1. The first sliding base 44 is slidably disposed on the first slide rail 61 and slides along the length of the processing table 1. The ion air knife 42 is disposed on the first sliding base 44. The second sliding base 45 is slidably disposed on the first sliding base 44 and slides along the width of the processing table 1. The lifting cylinder 46 is disposed on the second sliding base 45, and the output end of the lifting cylinder 46 extends and retracts along the height of the processing table 1. The laser 41 and the positioning camera 43 are both disposed on the output end of the lifting cylinder 46.

[0066] This design allows the laser 41 to move freely in the X / Y / Z directions, which facilitates processing at any position of the FPC roll 10 on the processing station 21, increasing the versatility and accuracy of the laser 41 in this application.

[0067] In a preferred embodiment, the laser processing mechanism 4 also includes a cutting component 71 and a traction gripper 47. The cutting component 71 is disposed at the feeding conveyor 31 and is used to cut the FPC roll 10. The traction gripper 47 is disposed on the first sliding seat 44 and is used to pull the FPC roll 10 cut by the cutting component 71.

[0068] Specifically, after being pulled to the FPC roll 10 by the discharge conveyor 32, the FPC roll 10 can be cut by the cutting component 71 and then laser-cut. After the cutting is completed, the cut FPC roll 10 is clamped by the traction gripper 47 and pulled to the discharge conveyor 32, thereby completing the next feeding process.

[0069] In a preferred embodiment, the laser processing mechanism 4 further includes a laser dust collection hood 48 and a small waste dust collection hood 49. The laser dust collection hood 48 is disposed on the second sliding seat 45 and located below the laser 41. The laser dust collection hood 48 has a processing through hole 481 for the laser to pass through, and a dust collection hole 482 is provided on the inner side of the processing through hole 481. The laser dust collection hood 48 is used to adsorb micro dust. The small waste dust collection hood 49 is disposed on the first sliding seat 44 and located on the side of the ion air knife 42 near the discharge conveying component 32 in the length direction of the processing table 1. The small waste dust collection hood 49 is used to adsorb micro dust.

[0070] In practice, both the laser dust collection hood 48 and the small waste dust collection hood 49 are equipped with a fan dust collection system. The laser dust collection hood 48 is used to adsorb the micro dust generated during the cutting process, and the small waste dust collection hood 49 is used to adsorb the micro dust generated when the ion air knife 42 blows the material.

[0071] In a preferred embodiment, the material gripping mechanism 5 includes a mounting beam 51, mounting side frames 52, and negative pressure suction cups 53. The mounting beam 51 moves in the width direction of the processing table 1. Multiple mounting side frames 52 are all disposed on the mounting beam 51, and the multiple mounting side frames 52 are equidistantly distributed in the length direction of the processing table 1. Multiple negative pressure suction cups 53 are respectively disposed on each mounting side frame 52 for adsorbing FPC material or partitions.

[0072] In practice, the negative pressure suction cup 53 on the mounting beam 51 can cover the processing station 21 along the length of the processing table 1, and two adjacent negative pressure suction cups 53 are used to pick up the finished product and the outer frame waste, respectively.

[0073] In a preferred embodiment, the material gripping mechanism 5 further includes an assembly bolt 54, wherein a waist-shaped hole 521 is provided on the mounting side frame 52, and the negative pressure suction cup 53 moves through the waist-shaped hole 521 in the width direction of the processing table 1, and the assembly bolt 54 is used to position the moving position of the negative pressure suction cup 53 relative to the waist-shaped hole 521.

[0074] In practice, by adjusting the insertion position of the negative pressure suction cup 53 on the waist-shaped hole 521 and fixing it with the mounting bolt 54, it is easy to adjust the position of the negative pressure suction cup 53, so that the negative pressure suction cup 53 can be adapted to the adsorption treatment of FPC rolls 10 of different shapes, making it convenient to use.

[0075] Preferably, the processing table 1 is provided with a second slide rail 62 and a third sliding seat 63, the third sliding seat 63 is slidably disposed on the second slide rail 62, and the mounting beam 51 is mounted on the third sliding seat 63.

[0076] In a preferred embodiment, the device also includes a feeding roller 72 and a limiting frame 73. The two feeding rollers 72 are rotatably disposed at the feeding conveying component 31, and the FPC roll 10 passes over the bottom and top of the two feeding rollers 72 respectively. The limiting frame 73 is disposed on the side of the feeding rollers 72 away from the feeding conveying component 31, and the limiting frame 73 is provided with a limiting hole 731 for the FPC roll 10 to pass through.

[0077] This design, with the constraints of the feeding roller 72 and the limiting frame 73, increases the stability of the FPC roll 10's feeding position, thereby facilitating the feeding of the FPC roll 10 close to the processing station 21 and making it convenient to use.

[0078] This invention also proposes a laser cutting method for flexible printed circuit boards (FPCs) used in new energy batteries, including the aforementioned laser cutting device for flexible printed circuit boards (FPCs) used in new energy batteries, and further including the following steps:

[0079] S1. The FPC roll 10 is conveyed through the feeding conveyor 31 and the discharging conveyor 32, and the FPC roll 10 is flattened and adsorbed on the processing station 21.

[0080] S2. The FPC roll 10 on the processing station 21 is laser-processed by the laser processing mechanism 4.

[0081] S3. After laser processing is completed, the material gripping mechanism 5 simultaneously picks up the cut product and the outer frame waste on the processing station 21, and transports the cut finished product to the finished product station 22 to complete the finished product unloading. Then, the outer frame waste is transported to the first waste collection port 24 to complete the frame waste unloading.

[0082] S4. Adjust the material grabbing mechanism 5 to pick up the partition at the partition placement station 23 and transport it to the finished product at the finished product station 22;

[0083] S5. Move the ion air knife 42 to one side of the feeding conveyor 31 and start the ion air knife 42. Adjust the ion air knife 42 to move closer to the discharge conveyor 32 and blow the cutting waste into the interior of the second waste collection port 25.

[0084] S6. After the waste material is cleaned, the traction gripper 47 clamps the cut opening of the previous sheet, the fixing plate of the FPC roll 10 is released, and the FPC roll 10 is pulled to the right until it reaches the discharge conveyor 32. The cutting component 71 cuts the FPC roll 10, completing the second round of feeding.

[0085] S7. Repeat steps S2 to S6 to complete the processing of FPC roll 10.
