[0008] In one embodiment, the conveyor includes a conveyor chain and support members, the conveyor chain being rotatable about an axis parallel to a first direction, and a plurality of support members being disposed at intervals on the conveyor chain, the support members being used to carry the workpiece.
[0009] In one embodiment, the support member includes a body and a protrusion. The body is disposed on the conveyor, and the protrusion is disposed on the side of the body opposite to the conveyor. A plurality of the protrusions are sequentially protruding from the body along a first direction.
[0010] In one embodiment, the carrying device further includes a first transmission gear, a second transmission gear, and a driving member. The first transmission gear and the second transmission gear are spaced apart from each other along a second direction. The transmission chain is sleeved on the first transmission gear and the second transmission gear. The driving member is tractively connected to at least one of the first transmission gear and the second transmission gear to drive at least one of the first transmission gear and the second transmission gear to rotate about an axis parallel to the first direction.
[0011] The first direction and the second direction intersect each other.
[0012] In one embodiment, the carrying device further includes a support base disposed on one side of the conveyor along the second direction, wherein the first cleaning component and the second cleaning component are disposed spaced apart from each other on the support base along the second direction;
[0013] The first direction and the second direction intersect each other.
[0014] In one embodiment, the first cleaning component includes a cleaning member and a connector, the connector being connected between the cleaning member and the support base, and the connector being configured to provide the cleaning member with a spring force toward the conveyor.

[0019] In the aforementioned carrier device, after the workpiece at a preset position on the conveyor is laser-cut, the conveyor rotates around an axis parallel to the first direction, causing the preset position to pass through a first cleaning component. One end of the first cleaning component abuts against the conveyor, thereby removing the residue, or slag, left on the workpiece at the preset position after laser cutting. The conveyor then continues to rotate around the axis parallel to the first direction, causing the preset position to pass through a second cleaning component, which sprays cleaning agent onto the preset position. Thus, the dual slag removal through two cleaning components significantly improves the cleaning capability of the carrier device.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0035] In laser cutting, the workpiece is typically placed on a base, and the laser cutter is positioned above it to cut the workpiece. During cutting, slag is ejected from the cut and falls onto the base below, causing damage. This is especially true when the workpiece is a sheet metal. In related technologies, when the laser contacts the metal surface for cutting, the area where the workpiece and laser come into contact instantly vaporizes and melts, and is carried away by a high-pressure protective gas from above. This creates a three-phase jet of gas, liquid, and solid below. After escaping the cut, the high-pressure jet expands and scatters rapidly due to the pressure difference. The gaseous and molten metal flow condenses upon contact with the base, covering and adhering to it, forming slag. Over time, the base accumulates a large amount of slag, which is difficult to clean and easily damaged.
[0036] Furthermore, when the laser contacts the workpiece surface, causing localized vaporization and melting, some laser light spills out, sometimes even directly onto the base. Although the laser does not directly focus on the base, and the laser energy per unit area is insufficient to vaporize or melt the workpiece, the spilled laser light can cause a rapid change in the local temperature of the base due to factors such as continuous irradiation time, power fluctuations, and focal length changes. The base is generally made of economical materials with poor thermal shock resistance, making it prone to softening when heated to red-hot temperatures. This results in complex internal stresses within the base, leading to structural distortion, cracking, and breakage.
[0037] The above problem is usually solved by replacing the base after a certain working cycle in related technologies. However, in the later stages of the working cycle, a lot of splatter residue usually adheres to the base. If the workpiece is placed on the base at this time, the splatter residue will obviously also cause damage to the workpiece, resulting in workpiece damage and reduced quality.
[0038] Based on this, this application provides a carrier device and a laser cutting equipment that have better cleaning capabilities, can remove residues on the conveyor in a timely manner during the cutting process, reduce the impact of accumulated residues on the conveyor and the workpiece, thereby improving cutting quality and production efficiency.
[0039] See Figure 1 and Figure 2 As shown, Figure 1 This is a side view of the support device 10 in one embodiment of the present application along the first direction F1. Figure 2 This is a top view of the support device 10 in one embodiment of this application.
[0040] The carrying device 10 provided in this application includes a conveyor, a first cleaning component, and a second cleaning component. The conveyor is used to carry the workpiece 20 and can rotate about an axis parallel to the first direction F1. In this way, the conveyor can rotate in time after cutting, and sequentially send the cut area to the first cleaning component and the second cleaning component for cleaning, thereby achieving continuous cleaning and improving cleaning efficiency.
[0041] The first cleaning component is located on one side of the conveyor. One end of the first cleaning component can abut against the conveyor and remove any adhering substances from the conveyor. The first cleaning component can effectively remove residue from the surface of the conveyor through physical contact, preventing residue accumulation from affecting subsequent cutting.
[0042] The second cleaning component is located on the side of the conveyor close to the first cleaning component. The second cleaning component sprays cleaning agent onto the conveyor, which passes sequentially through the first and second cleaning components at a predetermined position. By spraying cleaning agent, the second cleaning component further removes tiny residues and stains from the surface of the conveyor. Simultaneously, the presence of the cleaning agent also prevents adhesion during subsequent cutting, reducing residue buildup.
[0043] After the workpiece 20 at a preset position on the conveyor belt is laser-cut, the carrier device 10 provided in this application rotates around an axis parallel to the first direction F1, causing the preset position to pass through the first cleaning component. The first cleaning component removes the residue, or slag, left on the workpiece 20 at the preset position after laser cutting. Then, the conveyor belt continues to rotate around the axis parallel to the first direction F1, causing the preset position to pass through the second cleaning component, which sprays cleaning agent onto the preset position. Thus, the dual slag removal through two cleaning components significantly improves the cleaning capability of the carrier device 10. Furthermore, when other workpieces 20 to be cut are subsequently placed at the preset position for laser cutting, the cleaning agent at the preset position helps prevent residue left after laser cutting from adhering to the preset position, further enhancing the cleaning capability of the carrier device 10.
[0044] In some embodiments, in conjunction with reference Figure 2 and Figure 3 As shown, the conveyor includes a conveyor chain 11 and support members 12. The conveyor chain 11 is rotatable about an axis parallel to the first direction F1. Multiple support members 12 are spaced apart on the conveyor chain 11 and are used to support the workpiece 20. Continuous operation is achieved through conveying via the conveyor chain 11. The spaced support by multiple support members 12 reduces the contact area between the workpiece 20 and the conveyor, reducing the amount of debris ejected from the workpiece 20 during cutting from adhering to the conveyor, further reducing debris buildup on the conveyor. Simultaneously, the multiple support members 12 provide stable support for the workpiece 20.
[0045] In some embodiments, the support member 12 includes a body and protrusions. The body is disposed on the conveyor, and the protrusions are disposed on the side of the body opposite to the conveyor. A plurality of protrusions are sequentially protruding from the body along a first direction F1. The design of the protrusions can effectively support the workpiece 20, while further reducing the contact area between the workpiece 20 and the conveyor, thereby reducing the adhesion of residue.
[0046] In some embodiments, see Figure 2 and Figure 3 The support member 12 can be a toothed plate. The toothed plate has a simple structure, good support effect, and can effectively reduce the contact area between the workpiece 20 and the conveying component, thereby reducing the adhesion of residue.
[0047] In some embodiments, such as Figure 1 The carrying device 10 further includes a first transmission gear 13, a second transmission gear, and a driving member. The first transmission gear 13 and the second transmission gear are spaced apart from each other along a second direction F2. The conveyor chain 11 is sleeved around the first transmission gear 13 and the second transmission gear. The driving member is tractively connected to at least one of the first transmission gear 13 and the second transmission gear to drive the first transmission gear 13 and the second transmission gear to rotate about an axis parallel to the first direction F1, wherein the first direction F1 and the second direction F2 intersect each other. In this way, the conveyor can rotate smoothly, which helps to improve the stability of the workpiece 20 during the cutting and cleaning process.
[0048] In some embodiments, such as Figure 2 The conveyor includes two conveyor chains 11, which are spaced apart from each other along a first direction F1. Both conveyor chains 11 are mounted on a first transmission gear 13 and a second transmission gear. A support member 12 extends along the first direction F1 and is mounted on the two conveyor chains 11. The design of the two conveyor chains 11 enables the conveyor to carry the workpiece 20 more stably and promptly delivers the pre-set area that carried the workpiece 20 to the cleaning component for cleaning after cutting, in preparation for carrying the workpiece 20 again, thereby achieving continuous operation.
[0049] It should be noted that the conveyor of this application carries the workpiece 20 and promptly sends the preset area that carried the workpiece 20 to the cleaning component for cleaning after the workpiece 20 is cut. This process can be carried out in conjunction with a robotic arm to achieve the steps of grasping and placing the workpiece 20. In other words, the rotation and transportation process of the conveyor does not affect the placement and removal of the workpiece 20, which will not be elaborated here.
[0050] In some embodiments, in conjunction with reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, Figure 4This is a schematic diagram of the structure of the first and second cleaning components mounted on the support base 14 in one embodiment of this application. The carrying device 10 also includes the support base 14, which is located on one side of the conveyor along the second direction F2. The first and second cleaning components are spaced apart from each other on the support base 14 along the second direction F2. The design of the support base 14 provides a stable mounting platform for the first and second cleaning components, improving the stability and reliability of the cleaning process.
[0051] Furthermore, the support base 14 allows the two cleaning components to be mounted on an external structure, such as on a machine base used to carry the conveyor, thereby enabling the two cleaning components to be stably positioned relative to the conveyor.
[0052] In some embodiments, such as Figure 1 The first cleaning component includes a cleaning member 15 and a connector, the connector being connected between the cleaning member 15 and the support base 14, and the connector being configured to provide the cleaning member 15 with a spring force toward the conveyor direction.
[0053] In some embodiments, continue reading Figure 1 The connector includes a guide rod 16 and an elastic element 17. The guide rod 16 is mounted on the support base 14. Along the extension direction of the guide rod 16, the cleaning element 15 is slidably connected to the guide rod 16. The elastic element 17 is sleeved on the guide rod 16, with one end connected to the end of the guide rod 16 away from the cleaning element 15, and the other end connected to the cleaning element 15. This design allows the cleaning element 15 to tightly adhere to the surface of the conveyor under elastic force, improving the cleaning effect. Especially when multiple supports 12 are spaced apart, the elastic force drives the cleaning element to extend between two adjacent supports 12 to clean the sides of the supports 12, and the elastic force does not affect the passage of the cleaning element 15 through the supports 12.
[0054] In some embodiments, continue reading Figure 1 The extension direction of the guide rod 16 is parallel to the direction of gravity. Thus, the elastic force provided by the elastic element 17 coincides with the direction of gravity. It is understandable that if the extension direction of the guide rod 16 were tilted relative to the direction of gravity, the guide rod 16 and the elastic element 17 would be affected by the component of gravity, and the cleaning element 15 itself, being tilted, would also be affected by the component of gravity. Therefore, with prolonged use, the elastic element 17 and the cleaning element 15 are prone to tilting to one side and causing damage. In this application, the extension direction of the guide rod 16 is parallel to the direction of gravity, which helps protect the connector and improves its service life.
[0055] In some embodiments, see Figure 1 and Figure 4As shown, the cleaning component 15 includes a brush body and bristles disposed on the brush body. The axis of the bristles is parallel to the direction of gravity, and the end of the bristles away from the brush body faces the conveyor. This makes the bristles less susceptible to the influence of the component of gravity, less prone to skewing or collapsing, and helps to keep the bristles in a straight state, providing stable and reliable cleaning for the conveyor.
[0056] In some embodiments, the brush body is made of aluminum, and the bristles are made of steel. The bristles can be made of steel wire with a diameter in the range of 0.7mm-1.0mm, and the bristle diameter can be 0.7mm, 0.9mm, or 1.0mm. The bristle length can be 60mm-65mm, such as 60mm, 62mm, 64mm, or 65mm. The area on the brush body with bristles can be a rectangle with a length of 1850mm and a width of 60mm. Meeting the above conditions ensures that the bristles have sufficient strength and wear resistance, effectively removing residue from the surface of the conveyor, and that the size of the bristle area along the first direction F1 is not less than the size of the conveyor along the first direction F1. The bristle area can cover all parts of the conveyor along the first direction F1, facilitating thorough cleaning of the conveyor.
[0057] In some embodiments, see Figure 1 Combined with reference Figure 4 As shown, the second cleaning assembly includes a nozzle 18 and a bracket 19. The bracket 19 connects the nozzle 18 and the support base 14, and the nozzle 18 can rotate relative to the bracket 19 about an axis parallel to the first direction F1. This allows for flexible adjustment of the spray angle of the nozzle 18, enabling the cleaning agent to evenly cover the surface of the conveyor.
[0058] In some embodiments, such as Figure 4 The carrier device 10 includes a plurality of second cleaning components, which are spaced apart from each other on the support base 14 along the first direction F1. In this way, the cleaning agent can be evenly covered on all parts of the surface of the conveyor along the first direction F1, thereby improving the cleaning effect.
[0059] In some embodiments, the carrier device 10 further includes a liquid tank, a solenoid valve, and a liquid supply pipe. The input end of the liquid supply pipe is connected to the liquid tank, and the output end of the liquid supply pipe is connected to a plurality of nozzles 18. The solenoid valve is disposed on the liquid supply pipe and is used to drive the cleaning agent in the liquid tank to flow through the liquid supply pipe to the plurality of nozzles 18 for spraying. By controlling the solenoid valve, the flow rate of the cleaning liquid in the liquid supply pipe can be adjusted, thereby flexibly controlling and adjusting the spray pressure of the cleaning agent according to the needs, which is beneficial to improving the cleaning effect.
[0060] In some embodiments, nozzle 18 may be an atomizing nozzle, and the air pressure emitted by nozzle 18 is electrically controlled by a solenoid valve within the range of 0.2 bar to 0.5 bar. The air pressure of nozzle 18 can be 0.2 bar, 0.3 bar, 0.4 bar, or 0.5 bar. The maximum spray distance of nozzle 18 in a static environment is approximately 1000 mm, the air consumption is 250 liters / hour to 350 liters / hour, and the liquid consumption is 6 liters / hour. Meeting the above ranges allows the cleaning agent to uniformly cover the surface of the conveyor, improving the cleaning effect.
[0061] In some embodiments, the horizontal diffusion angle of the cleaning agent sprayed from nozzle 18 is in the range of 60°-70°, and the vertical diffusion angle is in the range of 8°-20°, to facilitate uniform spraying onto the conveyor. For example, the horizontal diffusion angle of the cleaning agent sprayed from nozzle 18 can be 60°, 65°, 67°, 69°, or 70°, and the vertical diffusion angle can be 8°, 10°, 13°, 17°, or 20°. Meeting the above ranges ensures that the cleaning agent can be fully and comprehensively sprayed onto the preset positions on the conveyor, reducing the occurrence of cleaning agent leakage in some areas of the preset positions on the conveyor.
[0062] In some embodiments, the cleaning agent may be a slag remover or a splash inhibitor to further remove slag or reduce the splashing of residue left on the workpiece after laser cutting.
[0063] This application also provides a laser cutting device, including the support device 10 in any of the above embodiments. The laser cutting device further includes a laser cutter, which is disposed on one side of the support device 10 and used to cut the workpiece 20 on the support device 10. By using the above-described support device 10, the laser cutting device can achieve continuous cutting and cleaning, thereby improving production efficiency and product quality.
[0064] The carrier device 10 and laser cutting equipment of this application, through the cooperation of a first cleaning component and a second cleaning component, first physically remove residue and then spray cleaning agent, achieving dual cleaning of the conveyor component, effectively removing the adhering substances generated during the cutting process, and significantly improving the cleaning capability of the carrier device 10. The conveyor component adopts a combination of a conveyor chain 11 and multiple support components 12. The support components 12 are provided with protrusions, which can effectively support the workpiece 20 and reduce the contact area, reduce residue adhesion, and ensure the stability of the workpiece 20 during the cutting process. The first cleaning component adopts a flexible brush body structure with optimized bristle material and size, which can reach into the gaps of the support components 12 for cleaning. The second cleaning component adopts an adjustable-angle nozzle 18, which sprays evenly and adapts to different cleaning needs. The cleaning agent can be a slag remover or an anti-splatter agent, which not only removes residue but also reduces the adhesion of splatter in subsequent cutting, further improving the cleaning effect and cutting quality. Moreover, the spray pressure and flow rate of the cleaning agent are controlled by a solenoid valve, which, in conjunction with the atomizing nozzle 18, achieves precise spraying, saving cleaning agent consumption while improving cleaning efficiency.
[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
