[0003] The utility model with the publication number CN208178726U proposes a FPC laser cutting device, including a cutting component and a fixing component, wherein the cutting component includes a base, a motor, a roller, a belt, a laser head, a conveyor belt, a cross bar and a slide bar, wherein the base is fixedly connected to the motor, the motor is located above the base, and the motor is connected to the roller through the belt drive; the FPC is placed on the conveyor belt, at which time the conveyor belt drives the FPC to move to the left above the support, and the fan draws the air inside the support outward through the air duct. However, when cutting the FPC coil, not only the outer frame waste outside the finished product will be generated, but also the cutting waste will be generated due to the cutting. Since the outer frame waste and the cutting waste have different physical properties and need to be collected and processed separately, the above-mentioned FPC laser cutting equipment is not convenient for collecting and processing the finished product, outer frame waste and cutting waste generated after laser cutting separately, so this scheme specially proposes a laser cutting device and method for FPC flexible circuit boards for new energy batteries to solve the above problems.

By setting the material grabbing mechanism to pass through the partition placement station when moving, the material grabbing mechanism can also grab the partition and place it on the finished cutting products to block each finished cutting product from each other, so as to facilitate the finished product station to collect multiple finished cutting products at one time. By setting an ion air knife to blow the cutting waste, the effect of blowing and collecting the cutting waste is increased.

[0051] like Figures 1 to 6As shown, the laser cutting device for FPC flexible circuit boards of new energy batteries of the present invention is characterized in that it includes a processing table 1, a processing station 21, a finished product station 22, a partition placement station 23, a feeding conveying component 31, a discharging conveying component 32, a laser processing mechanism 4 and a material grabbing mechanism 5, wherein 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 sequentially distributed in the width direction of the processing table 1, the processing station 21 is used to support the FPC coil 10, the finished product station 22 is used to support the cutting of the finished product, the partition placement station 23 is used to support the partition, and the processing table 1 is provided with 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, and the second waste collection port 25 is used to store outer frame waste. The opening 25 is located on the side of the processing station 21 away from the feed conveying component 31 in the length direction of the processing station 21, and is used to store cutting waste; the feed conveying component 31 and the discharge conveying component 32 are respectively arranged at the two ends of the processing station 21 in the length direction of the processing station 21, and are both used to convey the FPC coil 10 in the length direction 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 coil 10 on the processing station 21, and the ion air knife 42 moves in the length direction of the processing station 21, and is used to blow the cutting waste on the processing station 21 to the second waste collection opening 25; the grabbing mechanism 5 moves between the processing station 21, the finished product station 22, the partition placement station 23 and the first waste collection opening 24, and is used to absorb FPC materials or partitions.

[0052] Figure 1 The X direction is the length direction of the processing table 1 , the Y direction is the width direction of the processing table 1 , and the Z direction is the height direction of the processing table 1 .

[0053] In a specific implementation, the FPC coil 10 is conveyed by the feed conveying component 31 and the discharge conveying component 32 to move in the length direction of the processing table 1. When the FPC coil 10 covers the processing station 21, the laser processing mechanism 4 completes the laser processing of the FPC coil 10 on the processing station 21. After the laser processing is completed, a finished cut product is generated. The grabbing mechanism 5 simultaneously grabs the finished cut product and the outer frame waste, 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 finished cut product and the outer frame waste. Then, the ion air knife 42 is adjusted to move in the length direction of the processing table 1 to blow the cutting waste on the processing station 21 to the inside of the second waste collection port 25, thereby completing the collection and processing of the cutting 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 cut products and the outer frame waste generated during cutting, and supply them to the processing station 21 and the first waste collection port 24 respectively, so as to complete the independent recycling of the finished cut products and the outer frame waste. By setting the material grabbing mechanism 5 to pass through the partition placement station 23 when moving, the material grabbing mechanism 5 can also grab the partition and place it on the finished cut products to block each finished cut product from each other, so that the finished product station 22 can collect multiple finished cut products at one time. By setting the ion air knife 42 to blow the cutting waste, the effect of blowing and collecting the cutting waste is increased. By setting the ion air knife 42 to move in the length direction of the processing table 1, it is convenient to blow the cutting waste on the entire processing station 21 to the second waste collection port 25 and collect it by adjusting the movement of the ion air knife 42 after the processing is completed, which is convenient for use.

[0055] Preferably, the processing station 21 is provided with a wind adsorption component for adsorbing the FPC coil 10 toward the table of the processing station 21, so as to make the FPC coil 10 close to the table of the processing station 21, so as to facilitate subsequent laser cutting processing.

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

[0057] With this design, the wavelength of laser 41 is shorter, which can achieve higher beam focusing and higher cutting accuracy, and is suitable for the processing of fine structures. The pulse width of the picosecond laser is extremely short (picosecond level), and very little heat is generated during the cutting process, which reduces the heat-affected zone, thereby reducing thermal deformation and damage to the material. If the power of laser 41 is lower than 15W, it cannot meet the cutting requirements of the FPC coil, resulting in slow cutting speed, poor cutting quality, or even the inability to cut the FPC coil. If the power of laser 41 is lower than 30W, it will cause the FPC coil material to overheat during cutting, resulting in a larger heat-affected zone, causing deformation, burning of the coil, or rough cutting edges.

[0058] Preferably, the processing table 1 of the present application is a marble table.

[0059] As a preferred embodiment, the feed conveying component 31 and the discharge conveying component 32 are both used to convey two FPC rolls 10, and the number of the processing station 21, the finished product station 22, the partition placement station 23 and the first waste collection port 24 are two, and are symmetrically distributed in the width direction of the processing table 1.

[0060] This design enables the processing table 1 of the present application to have two left and right workstations, and the two workstations are symmetrically distributed relative to the processing table 1. In specific implementation, the two workstations on the processing table 1 simultaneously perform cutting and material collection processing of two FPC coils 10, thereby increasing the laser processing efficiency of the FPC coils 10.

[0061] As a preferred embodiment, the laser processing mechanism 4 further includes a positioning camera 43 , on which a CCD visual positioning system is provided. The positioning camera 43 is used for visually inspecting the FPC coil 10 on the processing station 21 .

[0062] By setting the laser processing mechanism 4 to also include a positioning camera 43, when the laser 41 processes the FPC coil 10, the Mark mark on the FPC coil plate 10 can be identified and positioned in advance through the CCD visual positioning system on the positioning camera 43, thereby positioning the laser 41 to the position to be cut, so as to complete the accurate cutting of the FPC coil 10 and facilitate use.

[0063] Preferably, the pixel of the positioning camera 43 is 5 million, the camera field of view is ≥4mm*6mm, the alignment accuracy is less than or equal to ±5μm, and the light source specification is an LED light source.

[0064] Designed in this way, the 5-megapixel camera can provide clear images and ensure that details are captured, which is essential for accurately positioning and identifying small features (such as FPC flexible circuit boards). LED light sources have the characteristics of high brightness, low power consumption and long life, and can provide stable lighting conditions, reduce shadows and reflections, and improve image quality. In addition, the spectral range of the LED light source can be adjusted as needed to adapt to the reflective characteristics.

[0065] As a preferred embodiment, it also includes a first slide rail 61, and the laser processing mechanism 4 also includes a first sliding seat 44, a second sliding seat 45 and a lifting cylinder 46, wherein the first slide rail 61 is arranged on the processing table 1 and extends in the length direction of the processing table 1; the first sliding seat 44 is slidably arranged on the first slide rail 61 and slides in the length direction of the processing table 1, and the ion wind knife 42 is arranged on the first sliding seat 44; the second sliding seat 45 is slidably arranged on the first sliding seat 44 and slides in the width direction of the processing table 1; the lifting cylinder 46 is arranged on the second sliding seat 45, and the output end of the lifting cylinder 46 is retracted in the height direction of the processing table 1, and the laser 41 and the positioning camera 43 are both arranged on the output end of the lifting cylinder 46.

[0066] This design allows the laser 41 to move freely in the three directions of X / Y / Z, making it easier to process any position of the FPC coil 10 on the processing station 21, thereby increasing the versatility and accuracy of the laser 41 processing in this application.

[0067] As a preferred embodiment, it also includes a cutting component 71, and the laser processing mechanism 4 also includes a traction clamp 47, wherein the cutting component 71 is arranged at the feeding and conveying component 31, and is used to cut the FPC coil 10; the traction clamp 47 is arranged on the first sliding seat 44, and is used to pull the FPC coil 10 cut by the cutting component 71.

[0069] As a preferred embodiment, the laser processing mechanism 4 also includes a laser dust hood 48 and a small waste dust collection hood 49, wherein the laser dust hood 48 is arranged on the second sliding seat 45 and is located below the laser 41, and a processing through hole 481 for the laser to pass through is opened on the laser dust hood 48, and a dust collection hole 482 is opened on the inner side of the processing through hole 481, and the laser dust hood 48 is used to absorb dust; the small waste dust collection hood 49 is arranged on the first sliding seat 44, and is located on the side of the ion air knife 42 close to the discharge conveying component 32 in the length direction of the processing table 1, and the small waste dust collection hood 49 is used to absorb dust.

[0070] In a specific implementation, a fan dust collection system is provided inside the laser dust collection hood 48 and the small waste dust collection hood 49. The laser dust collection hood 48 is used to absorb the dust generated during the cutting process, and the small waste dust collection hood 49 is used to absorb the dust generated when the ion air knife 42 blows the material.

[0077] This design, under the restriction of the feeding roller 72 and the limiting frame 73, is used to increase the stability of the feeding position of the FPC coil 10, thereby facilitating the feeding of the FPC coil 10 close to the processing station 21 for easy use.
