[0036] Referring to Figures 1 to 8The utility model discloses a kind of laser cutting devices, comprising: laser emission module 10, conveying assembly 20, adsorption assembly 30 and rotating roller assembly 40, the adsorption assembly 30 is located above the conveying assembly 20, and gap is equipped between the adsorption assembly 30 and the conveying assembly 20, the rotating roller assembly 40 is located at one side of the conveying assembly 20, and region for placing material is formed between the rotating roller assembly 40 and the conveying assembly 20, the adsorption assembly 30 is used to adsorb the material, the material moves along the region, the laser emission module 10 is located at the side of the conveying assembly 20 away from the rotating roller assembly 40, and laser beam generated by the laser emission module 10 passes through the gap and acts on the material, to cut the material, the conveying assembly 20 is used to convey the waste generated after the material cutting.

[0037] Specifically, material transport assembly takes material from top to bottom along region, while material is adsorbed by adsorption assembly 30, to ensure the stability of material during laser processing, laser beam generated by laser emission module 10 passes through gap to cut material, two finished products and waste are formed after processing, and conveying assembly 20 is used to convey waste. Wherein, material includes but is not limited to film, tab belt and the like. Material transport assembly uses existing public technology, and no more elaboration is made here.

[0038] More specifically, by setting laser emission module 10 at the side of conveying assembly 20 away from rotating roller assembly 40, it can ensure that laser beam accurately passes through gap between adsorption assembly 30 and conveying assembly 20, and directly acts on material, to realize accurate and efficient cutting, and conveying assembly 20 undertakes the task of conveying waste after cutting, effectively avoids the decline of production efficiency caused by waste accumulation, and ensures the continuity and stability of cutting operation. In addition, adsorption assembly 30 is located above conveying assembly 20 to form gap, which not only ensures the smooth penetration of laser beam, but also realizes stable adsorption of material, avoids movement or deviation of material during cutting process, and ensures cutting accuracy. In addition, material placement region is formed between rotating roller assembly 40 and conveying assembly 20, and rotating roller assembly 40 is used to tension material, which is flexible in design and can adapt to materials of different sizes, shapes and materials, widening the application range of the device. In addition, the whole device is compact in structure and reasonable in layout, realizes continuous operation process of material from adsorption, cutting to waste treatment, and greatly shortens production cycle.

[0039] Reference Figures 1 to 4As shown, in an embodiment, the conveying assembly 20 comprises a conveying frame 21, a motor 22, a conveying belt 23 and a first negative pressure pipe 24. The motor 22 is fixed to the conveying frame 21, and the conveying belt 23 is installed on the conveying frame 21 and is drivingly connected to the motor 22. One end of the first negative pressure pipe 24 is connected to a dust removal machine or a vacuum pump, and the other end is connected to the conveying frame 21, so that the conveying frame 21 forms an adsorption cavity corresponding to the area of the conveying belt 23, which is used to adsorb the material, and the conveying belt 23 is used to convey the waste generated after the material is cut.

[0040] Specifically, the conveying frame 21 serves as the basic structure of the entire assembly and is usually made of a sturdy and durable metal material such as stainless steel or aluminum alloy to ensure its stability and durability. The motor 22 is fixed to one end or a suitable position of the conveying frame 21 and is stably connected to the conveying frame 21 by bolts or other fastening devices. The output shaft of the motor 22 is connected to the driving shaft of the conveying belt 23 through a transmission device such as a shaft coupling, a speed reducer, a chain or a belt, etc., to realize the continuous or intermittent movement of the conveying belt 23. The conveying belt 23 is wound around the rollers or pulleys of the conveying frame 21 to form a closed loop structure. The material of the conveying belt 23 needs to be selected according to the characteristics of the material and the cutting process, such as wear-resistant, high-temperature-resistant rubber or special synthetic materials. The surface of the conveying belt 23 can be designed with anti-slip texture or protrusions to increase the friction with the waste and prevent the waste from sliding during the conveying process. One end of the first negative pressure pipe 24 is connected to a dust removal machine or a vacuum pump through a pipe or a hose to realize a sealed connection, and the other end is connected to the conveying frame 21 to form one or more adsorption ports, which together constitute an adsorption cavity. The adsorption cavity and the adsorption assembly 30 are collectively adsorbed to the material to prevent the material from shifting during the laser cutting process.

[0041] More specifically, through the joint action of the adsorption cavity and the adsorption assembly 30, the material is effectively prevented from shifting during the laser cutting process, thereby improving the cutting accuracy and yield. In addition, the waste is adsorbed onto the conveying belt 23 by the negative pressure of the adsorption cavity, and then the conveying belt 23 is rotated by the motor 22, and under the action of the friction between the waste and the conveying belt 23, the waste moves with the conveying belt 23 to complete the conveying of the waste. In addition, the conveying belt 23 timely conveys the waste generated after cutting to avoid the accumulation of waste in the cutting area, which affects the cutting efficiency and safety. In addition, the design of the entire conveying assembly 20 realizes the dual functions of conveying waste and stabilizing the material, thereby improving the automation degree of the production line and the overall production efficiency.

[0042] Among them, the middle section of the first negative pressure pipe 24 is also provided with an adjusting valve for adjusting the size of the negative pressure to adjust the adsorption force of the adsorption cavity.

[0043] Referring to Figures 1 to 3 , Figure 5 andFigure 6 As shown, in an embodiment, the adsorption assembly 30 includes an adsorption frame 31 connected to the conveying frame 21, an adsorption plate 32 installed on the adsorption frame 31, and a second negative pressure pipe 33 having one end connected to a dust removal machine or vacuum pump and the other end connected to the adsorption plate 32, so that the adsorption plate 32 adsorbs the material.

[0044] Specifically, the adsorption frame 31 serves as the support structure of the adsorption assembly 30 and is usually made of lightweight but strong materials such as aluminum alloy or high-strength plastic to ensure its stability and durability while reducing overall weight. The shape and size of the adsorption frame 31 need to be set according to the size and shape of the material to ensure that the adsorption plate 32 can closely fit the material and provide sufficient adsorption area. The adsorption frame 31 is connected to the conveying frame 21 by bolts, buckles or other fastening devices to ensure its stability and reliability during operation. The adsorption plate 32 is the core component of the adsorption assembly 30 and is usually made of porous materials such as porous ceramics, foam metals or special synthetic materials, which have good air permeability and negative pressure adsorption capacity. The adsorption plate 32 is installed on the adsorption frame 31 and is firmly fixed on the adsorption frame 31 by bolts, adhesives or other fixing methods. The surface design of the adsorption plate 32 needs to consider the characteristics and cutting process of the material, such as surface roughness, hardness, etc., to ensure good adsorption effect and cutting accuracy. One end of the second negative pressure pipe 33 is connected to the dust removal machine or vacuum pump and is sealed connected by pipe or hose. The dust removal machine or vacuum pump provides continuous negative pressure suction to ensure that the adsorption plate 32 can firmly adsorb the material, and the other end is connected to the inside or edge of the adsorption plate 32 to form a negative pressure adsorption area. The design of the negative pressure pipe needs to consider the size, shape and cutting process of the material to ensure that the negative pressure suction can be evenly distributed on the entire adsorption plate 32. The adsorption cavity and the adsorption plate 32 jointly act on the material to form a strong adsorption force. The adsorption cavity is connected to the dust removal machine or vacuum pump through the first negative pressure pipe 24 on the conveying frame 21 to provide additional adsorption force to prevent the material from shifting due to vibration or air flow during laser cutting, and the adsorption plate 32 tightly fits the material through its porous structure and the suction force of the negative pressure pipe to provide stable support, and the two jointly act to ensure the stability and accuracy of the material during cutting.

[0045] More specifically, through the joint action of the adsorption cavity and the adsorption plate 32, stable adsorption and support of the material are achieved, effectively preventing the material from shifting and vibrating during laser cutting, thereby improving cutting accuracy and yield. In addition, the adsorption assembly 30 has high automation degree and works cooperatively with the material transportation assembly, the conveying assembly 20 and the laser emission module 10 to realize a continuous operation process of material conveying, cutting and waste collection, improving production efficiency.

[0046] Referring toFigure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, the side of the adsorption rack 31 is also connected to a first dust removal pipe 34, one end of the first dust removal pipe 34 is connected to the gap, and the other end is connected to a dust collector or a vacuum pump.

[0047] Specifically, the side of the adsorption rack 31 is designed with connection holes or flanges for a secure connection to the first dust removal pipe 34. The first dust removal pipe 34 is made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel or special synthetic materials, to ensure its long-term stable operation. The connection method can be bolt connection, flange connection, or quick coupling connection, depending on the actual application scenario and installation requirements. One end of the first dust removal pipe 34 is connected to the connection hole or flange on the side of the adsorption rack 31, and the other end extends to the installation position of the dust collector or vacuum pump. The dust collector or vacuum pump provides continuous negative pressure suction, which adsorbs and removes the dust generated on the front of the cutting material through the first dust removal pipe 34. The operating parameters of the dust collector or vacuum pump (such as suction strength, running time, etc.) need to be adjusted according to the characteristics of the cutting material and the cutting process to ensure the best dust removal effect. In addition, during laser cutting, a large amount of dust and exhaust gas are generated on the front of the cutting material. The first dust removal pipe 34 uses its negative pressure suction to adsorb and remove the dust and exhaust gas from the cutting area, preventing them from spreading and accumulating in the air.

[0048] More specifically, by promptly removing dust generated on the front side of the material being cut, the scattering and interference of dust on the laser beam are avoided, thereby improving cutting accuracy and yield. The dust removal system effectively reduces dust and exhaust emissions during the cutting process, lowering health hazards to operators and environmental pollution, improving the comfort and safety of the working environment, and contributing to increased operator satisfaction and work efficiency. Furthermore, the dust removal system is highly automated, working in conjunction with the laser emission module 10 to achieve a continuous cutting and dust removal process, reducing downtime and maintenance costs caused by dust accumulation, and improving overall production efficiency.

[0049] See Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, in one embodiment, a light-blocking component 50 is also provided on the same side of the rotating roller assembly 40. The light-blocking component 50 corresponds to the gap and is used to block the laser beam passing through the gap.

[0050] Specifically, the light-blocking component 50 is installed on the same side of the rotating roller assembly 40, corresponding to the position of the gap. The installation of the light-blocking component 50 must ensure that its relative position with the laser emitting module 10 is fixed to prevent its light-blocking effect from being affected by vibration or movement during processing.

[0051] More specifically, the light-blocking assembly 50 can effectively block the laser beam passing through the gap, preventing it from shining on unintended locations such as the eyes, skin or other sensitive parts of the operator, thereby greatly reducing the safety risks during the laser processing process. In addition, by precisely designing and installing the light-blocking assembly 50, it can be ensured that the laser beam will not affect other areas after penetrating the material due to scattering or reflection, thereby improving the accuracy and stability of the laser processing. In addition, the light-blocking assembly 50 can also prevent the laser beam from shining on the non-working area of other equipment, avoiding damage or failure of the equipment caused by excessive laser energy.

[0052] Referring to FIGS. 1-4, Figure 1 , Figure 2 , Figure 7 and Figure 8 , in an embodiment, the light-blocking assembly 50 includes a light-blocking box 51 and a light-blocking plate 52, the light-blocking plate 52 is installed on the light-blocking box 51, and the light-blocking plate 52 is directly opposite the laser beam passing through the gap.

[0053] Specifically, the light-blocking box 51 is generally designed as a box-shaped structure with sufficient strength and rigidity to withstand the heat and impact force that may be generated by laser irradiation. Its material is generally selected from metals such as stainless steel, aluminum, etc., which have good thermal conductivity and corrosion resistance, and can effectively protect the internal light-blocking plate 52 from the influence of the external environment. The front end of the light-blocking box 51 is open for receiving the laser beam passing through the gap, while the rear end is closed or provided with an opening for installing the light-blocking plate 52. The sidewalls and bottom of the light-blocking box 51 are designed with heat dissipation holes or fins to dissipate the heat generated by laser beam irradiation. The light-blocking plate 52 is a key component of the light-blocking assembly 50, which is used to directly block the laser beam. Its material is generally selected from materials with high reflectivity or high absorbance, such as metal plates (such as copper, aluminum, stainless steel, etc.) or plastics, which can effectively absorb or reflect laser light to prevent it from penetrating or scattering. The light-blocking plate 52 is installed at the rear end of the light-blocking box 51 and is securely installed by bolts, buckles or other fixing devices. The size and shape of the light-blocking plate 52 need to be customized according to the diameter of the laser beam, the divergence angle and the size of the light-blocking box 51 to ensure that it can completely cover the irradiation range of the laser beam. A sealing strip or sealant can be provided between the light-blocking plate 52 and the light-blocking box 51 to improve the light-blocking effect and prevent laser light from leaking from the gap.

[0054] More specifically, the light blocking assembly 50 can effectively block the laser beam passing through the gap, preventing it from shining on unintended locations such as the eyes, skin or other sensitive parts of the operator, thereby greatly reducing the safety risk during the laser processing process. In addition, the precise design and installation of the light blocking assembly 50 can ensure that the laser beam will not affect other areas after penetrating the material due to scattering or reflection, thereby improving the accuracy and stability of the laser processing. In addition, the design of the light blocking box 51 and the light blocking plate 52 facilitates disassembly and replacement, and when the light blocking plate 52 is worn or damaged due to long-term use, a new light blocking plate 52 can be conveniently replaced to ensure that the light blocking effect is always good.

[0055] Referring to Figure 7 and Figure 8 In an embodiment, the side of the light blocking box 51 is also connected with a second dust removal pipe 53, one end of the second dust removal pipe 53 is communicated with the light blocking box 51, and the other end is communicated with a dust removal machine or a vacuum pump.

[0056] Specifically, the diameter and length of the second dust removal pipe 53 need to be reasonably selected according to the suction force of the dust removal machine or vacuum pump, the amount of dust generated by material cutting, and the size of the working space, to ensure that the dust can be effectively adsorbed and carried away. The side of the light blocking box 51 is designed with a connecting port or a flange for connecting with the second dust removal pipe 53, and the size and shape of the connecting port or flange need to match the end of the second dust removal pipe 53 to ensure tight connection and no air leakage. When connecting, sealing elements such as gaskets, sealants or clamps can be used to improve the sealing and stability of the connection. The other end of the second dust removal pipe 53 is connected to the dust removal machine or vacuum pump to provide sufficient suction force to adsorb and carry away the dust. The selection of the dust removal machine or vacuum pump needs to be reasonably selected according to the amount of dust generated by material cutting, the properties of the dust and the requirements of the working environment.

[0057] More specifically, the design of the second dust removal pipe 53 can effectively adsorb and carry away the dust generated on the back during the material cutting process, thereby keeping the working environment clean and tidy. In addition, by reducing the dust concentration in the working environment, the risk of the operator inhaling dust is reduced, thereby protecting the health of the operator.

[0058] Referring to Figures 1 to 3 In an embodiment, the rotating roller assembly 40 includes an upper rotating roller 41 and a lower rotating roller 42, both of which abut against the material for tensioning the material.

[0059] Specifically, the upper rotating roller 41 and the lower rotating roller 42 are generally designed as cylindrical shapes, and their surfaces can be specially treated, such as coating, polishing, or grooving, according to the material type and processing requirements, to improve the friction and wear resistance with the material. The material of the rotating roller is generally selected from metal (such as stainless steel, carbon steel, etc.) or special plastic, which has sufficient strength and rigidity to withstand the pressure and friction force generated when the material is tensioned. When the material passes through the rotating roller assembly 40, the upper rotating roller 41 and the lower rotating roller 42 simultaneously abut the material and tension it through friction, which helps to maintain the stability and accuracy of the material and prevents it from shifting or relaxing during processing or transmission. In addition, the rotation speed of the upper rotating roller 41 and the lower rotating roller 42 can be adjusted according to the material type and processing requirements to ensure that the material is transmitted at an appropriate speed.

[0060] In an embodiment, the laser emitting module 10 includes a first laser emitter and a second laser emitter, which are arranged horizontally left and right or vertically up and down. The light beams generated by the first laser emitter and the second laser emitter form two groups of laser beams that pass through the gap and act on the middle part of the material to cut the material.

[0061] Specifically, the first laser emitter and the second laser emitter are arranged horizontally left and right, i.e., horizontally cutting lugs or staggered distribution cutting lugs; the first laser emitter and the second laser emitter are arranged vertically up and down, i.e., the first group of laser processing left lugs and the second group of laser processing right lugs to cut the material to produce common waste and complete the slitting at the same time, improve the utilization rate of the material, and reduce the equipment station (cut from the middle of the material to form lugs on both sides). That is, the first laser emitter and the second laser emitter are arranged side by side in the horizontal direction, and their laser beams cut from the middle of the material. Compared with traditional double-sided edge cutting, traditional double-sided edge cutting produces waste on both sides during processing, and subsequent slitting is required. In contrast, the middle cutting forms lugs and only produces one piece of waste, saving materials and completing the slitting function at the same time. Compared with traditional cutting, one station is reduced, and the dust generated by cutting is concentrated. The first laser emitter and the second laser emitter are arranged vertically up and down, and their laser beams pass through the gap from the top and bottom of the material and intersect on the material, also forming a cutting path. This configuration is suitable for situations that require simultaneous cutting from the top and bottom. The power, focal length, and angle of the laser beam can be adjusted according to the material type, thickness, and cutting requirements. For example, for thicker materials, the laser power and focal length can be appropriately increased; for situations that require fine cutting, the angle and shape of the laser beam can be adjusted. The intersection point of the laser beams can be achieved by precisely controlling the position and angle of the laser emitters to ensure the accuracy and stability of the cutting path.

[0062] In an embodiment, the laser emitting module 10 comprises a composite laser emitter which generates two sets of laser beams to act on the material through the gap to cut the material.

[0063] Specifically, the composite laser emitter can be in a horizontal cutting tab or a staggered distribution cutting tab. Alternatively, the composite laser emitter can be configured to split a single laser beam into two beams through a diffractive optical element (including but not limited to a DOE, a shaping mirror, a beam splitter, a light splitter, etc.), and the two beams can be in a horizontal cutting tab or a staggered distribution cutting tab. That is, the composite laser emitter can internally contain two independent laser sources, or can simultaneously generate two laser beams through a laser source and an optical system (such as a beam splitter), and the power, wavelength and focusing characteristics of the two beams can be adjusted according to the cutting requirements. Alternatively, the composite laser emitter can contain a laser source and a diffractive optical element (such as a diffraction grating, a holographic element, etc.). The single beam generated by the laser source is split into two or more beams through the diffractive optical element, and the beams have specific angles and intensity distributions to meet the cutting requirements. Regardless of whether the two beams are generated directly or split through the diffractive optical element, the two beams need to pass through appropriate guiding and focusing systems to ensure that they can accurately pass through the gap and act on the material, which usually includes lenses, mirrors and / or optical fibers.

[0064] More specifically, because the laser trajectory is moving diagonally downward in the absolute coordinate system (stationary object), the laser cutting of the material is a horizontal trajectory because the material is moving downward (relative coordinate system). The movement of the material cancels out the downward movement of the laser, so the laser does not produce displacement in the vertical direction relative to the material. When the material width is wider, the trajectory of the laser cutting of the edge is longer, and when the laser trajectory is decomposed into the horizontal direction and the vertical direction, the length is longer and the vertical height is higher.

[0065] The above embodiment is a preferred implementation scheme of the present application, in addition to this, the present application can also be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the present application.
