Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] Please see Figure 1 , Figure 2 as well as Figure 3This embodiment provides a laser die-cutting device, including a roller 2, a support assembly 3, a laser 4, and a width adjustment assembly 5. The roller 2 is fixedly connected to the support assembly 3. The roller 2 is used to convey a material strip 1 along a first direction. The width direction of the material strip 1 is a second direction, and the direction perpendicular to the material strip is a third direction. Preferably, in this embodiment, the first direction is vertically downward. The support assembly 3 includes a vertical plate 31 and a support plate 32. The vertical plate 31 is vertically arranged, and the support plate 32 is horizontally arranged. One end of the support plate 32 is fixedly connected to the vertical plate 31, and the other end is fixedly connected to the fixed end of the width adjustment assembly 5. In traditional designs, the laser 4 is supported by a frame and a base plate. During installation and debugging, workers must squat or stand on the frame to work, which is inconvenient for movement and observation. In this embodiment, workers only need to stand to perform installation and debugging. In addition, this embodiment eliminates the design of a frame, reducing manufacturing costs. Preferably, the laser 4 and the width adjustment assembly 5 are set in two groups, corresponding to both sides of the material strip 1 along the second direction, so as to cut both sides of the material strip 1 respectively. Preferably, the laser die-cutting device further includes a focus adjustment component 6. The fixed end of the focus adjustment component 6 is fixedly connected to the moving end of the width adjustment component 5. The laser 4 is fixed to the moving end of the width adjustment component 5, and the emitting end of the laser 4 is arranged along a third direction. The moving end of the focus adjustment component 6 is fixedly connected to the laser 4, and the focus adjustment component 6 can move along the third direction. It should be noted that the fixed end of the width adjustment component 5 is fixed to the support component 3, and the moving end of the width adjustment component can move along the second direction. Both the width adjustment component 5 and the focus adjustment component 6 can adopt a combination of motor and linear module to achieve precise quantitative movement. When the width of the material strip 1 is changed, since the laser beam range of the laser 4 is limited, the laser 4 needs to be adjusted when the width changes greatly. At this time, the width adjustment component 5 is driven, so that its motor drives the linear module to move, which drives the focus adjustment component 6 and the laser 4 to move together along the second direction, thereby changing the cutting position of the laser 4 on the material strip 1. When it is necessary to adjust the focus of the laser 4, the motor of the focus adjustment device drives the corresponding linear module, so that the laser 4 moves along the third direction.

[0033] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6The belt assembly 7 is fixedly connected to the moving end of the width adjustment assembly 5. The belt assembly 7 is also configured with two parts corresponding to the two sides of the material belt 1 along the second direction. The belt assembly 7 includes two cavity plates 71, multiple cavity connecting plates 72, multiple belt rollers 73, and a belt 74. The two cavity plates 71 are arranged in parallel and are fixedly connected by multiple cavity connecting plates 72. The two cavity plates 71 and the multiple cavity connecting plates 72 together form a first cavity 75. The first cavity 75 is connected to the negative pressure pipe 2a. The cavity connecting plate 72 near the material belt 1 has a through hole, which causes the material belt 1 to be adsorbed onto the belt 74. The belt 74 corresponds to the position after the laser 4 cuts. The belt 74 will also absorb the waste material after cutting. The lower side of the belt 74 is designed with a certain slope to facilitate the separation of waste material. Multiple belt rollers 73 are set outside the first cavity 75, and the two ends of the belt rollers 73 are rotatably connected to the two cavity plates 71 respectively. The belt 74 is wrapped around the periphery of the multiple belt rollers 73. One belt roller 73 is connected to the drive unit. In order to make the belt 74 taut, at least one belt roller 73 is designed to be able to move along the direction of belt 74. The drive unit drives the belt roller 73 to rotate, thereby driving the belt 74 to rotate. Its movement speed is consistent with the speed of the material belt 1. Preferably, the belt assembly 7 further includes a slide rail 76 and a fixing plate module 77. A cavity plate 71 and the fixing plate module 77 are slidably connected by the slide rail 76, and the slide rail 76 is arranged along a third direction. The fixing plate module 77 includes a first fixing plate 771, a second fixing plate 772, and a third fixing plate 773. The first fixing plate 771 is fixedly connected to the cavity plate 71, and the second fixing plate 772 is fixedly connected to the third fixing plate 773. The slide rail 76 is fixed to the second fixing plate 772. Therefore, changing the position of the first fixing plate 771 can change the belt position. The positions of belt 74 and cavity plate 71 are determined by fixing the first fixing plate 771 to the second fixing plate 772 and the third fixing plate 773 with a bolt. Since the first fixing plate 771 is located on both sides of the second fixing plate 772 and the third fixing plate 773, and the two bolts are installed in the same direction, rotating the two bolts in the same direction can move the first fixing plate 771 in two opposite directions and achieve positioning of the first fixing plate 771. This design is for convenient adjustment of the position of belt 74. Preferably, belt assembly 7 also includes a brush 78, which is located on the side of belt 74 away from material belt 1, and is used to sweep off debris adhering to belt 74. Belt 74 generally adopts a circular cross-section to reduce the contact area with material belt 1 and facilitate the adsorption of waste. Belt assembly 7 also includes an air blower 79, which is located at the separation point of waste from material belt 1. Air blowing can blow the waste downward, thereby detaching the waste from the adsorption of belt 74.

[0034] Please see Figure 7 and Figure 8The cutting cavity assembly 8 contacts the material strip 1. The cutting cavity assembly 8 includes a first connecting block 81, an adsorption module 82, a first electrode tab roller 83, and a second electrode tab roller 84. Both the first electrode tab roller 83 and the second electrode tab roller 84 are connected to the first connecting block 81 for contacting both sides of the material strip 1 respectively. Their positions are adjustable along a third direction, and they feature an oblong hole design for easy adjustment. A second cavity 811 is formed within the first connecting block 81, which is used to connect to the negative pressure pipe 2a. The adsorption module 82 is connected to the first connecting block 81 to adsorb and position the material strip 1 along a third direction and on the side closer to the laser 4. The adsorption module 82 includes an adsorption plate 821 and an adsorption block 822. The adsorption plate 821 is fixedly connected to the adsorption block 822. The adsorption plate 821 has multiple through holes that contact the material strip 1. The adsorption plate 821 is connected to a negative pressure system, adsorbing the material strip into the electrode tab area to prevent the electrode tabs from vibrating during laser cutting. The heat sink 87 is located on the side of the first connecting block 81 away from the laser 4. The laser 4 and the heat sink 87 are located on opposite sides of the material strip 1 along a third direction. The heat sink 87 is fixed to the first connecting block 81 with a cover. In some special cases, the laser beam can be blocked when it hits the heat sink 87.

[0035] Please see Figure 7 , Figure 8 as well as Figure 10 Preferably, the cutting cavity assembly 8 further includes a filter module 85, which is disposed between the first connecting block 81 and the negative pressure pipe 2a. The filter module 85 includes a pull-out plate 851, a first filter screen 852, and a second filter screen 853. The pull-out plate 851 is fixedly connected to the first filter screen 852 on the side near the negative pressure pipe 2a, and the pull-out plate 851 is fixedly connected to the second filter screen 853 on the side near the first connecting block 81. The function of the first filter screen 852 and the second filter screen 853 is to block large-sized debris and electrode waste in some special cases. The area of ​​the second filter screen 853 is smaller than that of the first filter screen 852, so one end of the electrode waste will rest on the second filter screen 853 for easy removal by the operator. More preferably, the cutting cavity assembly 8 also includes an observation plate 86. The observation plate 86 is transparent and fixed to the first connecting block 81, allowing observation of the waste accumulation at the first filter screen 852 and the second filter screen 853.

[0036] Please see Figure 4 , Figure 7 as well as Figure 9Preferably, the laser die-cutting device further includes an air knife assembly 9. The air knife assembly 9 is used to apply airflow to the material belt 1 in a direction pointing outward from the center. The air knife assembly 9 includes a first air knife plate 91 and a second air knife plate 92, which are fixedly connected and enclose a third cavity 93 and an airflow slit 94 communicating with the third cavity 93. The third cavity 93 is used to connect to a positive pressure pipe. In this embodiment, the air knife assembly 9 is fixed on the belt assembly 7 and the cutting cavity assembly 8. The airflow blowing towards both sides of the material belt 1 can flatten the material belt 1. The air knife assembly 9, in conjunction with the negative pressure pipe 2a, removes the dust and smoke generated by laser cutting.

[0037] Preferably, the laser die-cutting device further includes a waste funnel 1a, which is located below the laser 4 and is used to collect waste material after the material strip 1 is cut. The waste funnel 1a is also connected to a negative pressure to suck out the waste material.

[0038] In summary, the laser die-cutting device provided in this application allows the width adjustment component to adjust the position of the laser as needed when the width of the material strip changes due to replacement, so that the laser can be adjusted to a suitable position to adapt to the change in the width of the material strip. Therefore, the device has a wide range of applications, and the entire process does not require workers to disassemble parts, resulting in high adjustment efficiency and improved production efficiency.
