Description

Technical Field

[0001] This invention belongs to the field of laser processing, specifically a laser cutting and welding integrated machine for thin stainless steel sheets. Background Technology

[0002] One type of stainless steel sheet requires laser cutting to remove irregular shapes at one end during processing, ensuring that this end is flat. This allows it to be joined with the flat ends of other stainless steel sheets and subsequently welded. In this process, the ends of two stainless steel sheets are laser-cut separately, and then joined and welded to complete the laser processing of the entire sheet.

[0003] A patent document with announcement number CN222037178U discloses an integrated metal plate cutting and welding machine, including a frame, two tracks and a first movable seat. A laser cutting head is connected to the first movable seat, and a second movable seat is provided on the upper right side of the track. A laser welding head is connected to the second movable seat. The track wheels can be driven to move left and right by a hub motor. The motor can drive the first rotating shaft and gear to rotate. Therefore, the top plate can drive the laser cutting head or laser welding head on it to move, achieving the purpose of moving back and forth and left and right, which can better meet the cutting and welding requirements.

[0004] In traditional processes, the irregular ends of stainless steel sheets require multiple manual steps such as cutting, butt welding, which results in low processing efficiency and high labor costs. At the same time, existing conveying devices are unable to achieve position positioning while being compatible with sheets of different widths, causing the ends to tilt or shift during laser cutting, which seriously affects the accuracy and quality of subsequent butt welding.

[0005] Therefore, the present invention provides a laser cutting and welding integrated machine for stainless steel thin plates to solve the problems mentioned in the background art. Summary of the Invention

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a laser cutting and welding integrated machine for stainless steel thin plates, including a machine tool and a multi-axis moving frame installed above the machine tool. A laser processing component is installed inside the multi-axis moving frame. The laser processing component is used to perform laser cutting and laser welding on the stainless steel thin plate. Feeding clamping tables are also fixedly installed on both sides above the machine tool. A conveying component is fixedly installed on one side of the feeding clamping table. A positioning conveying component is rotatably installed at one end of the conveying component. The two feeding clamping tables are located below the multi-axis moving frame. The conveying assembly has a conveying cavity inside, and the stainless steel sheet is conveyed inside the conveying cavity. The positioning conveying component includes a rotating plate rotatably installed on one side below the conveying table and multiple telescopic components fixedly installed on one side of the rotating plate. One end of each of the multiple telescopic components is fixedly installed with a conveying positioning frame.

[0007] Preferably, the feeding clamping platform has a feeding groove inside, and multiple fixed motors are fixedly installed on one side of the feeding clamping platform. A lower pressure plate is installed below the fixed motors and moves up and down. After the lower pressure plate descends, it cooperates with the bottom side of the feeding groove to clamp the stainless steel sheet.

[0008] Preferably, lifting frames are installed at both the upper and lower positions inside the conveying cavity, and multiple lifting frames are installed at both the upper and lower positions of the conveying platform.

[0009] Preferably, the multiple ends facing the conveying cavity are all fixedly connected to the side of the corresponding lifting frame through the conveying table, and the multiple ends are used to drive the two lifting frames to move up and down inside the conveying cavity.

[0010] Preferably, the lifting frame has an internal transmission system with a transmission belt component. The transmission belt component is driven by an electrical structure inside the lifting frame to perform conveying operations. The closest distance between the transmission belt component and the center of the conveying cavity is less than the closest distance between the lifting frame and the center of the conveying cavity.

[0011] Preferably, a strip groove is provided on one side of the inside of the conveyor table, and a second conveyor belt component is installed inside the strip groove. The second conveyor belt component is driven by the internal electrical structure of the conveyor table.

[0012] Preferably, a rotation adjustment shaft is rotatably installed on one side below the conveyor table. The rotation adjustment shaft is connected to the rotating plate, and the rotation of the rotation adjustment shaft is used to drive the entire positioning conveyor to rotate on one side of the conveying assembly.

[0013] Preferably, a conveyor frame is movably installed inside the conveyor positioning frame, and a conveyor belt component three is driven inside the conveyor frame to perform conveying work through an electrical structure inside the conveyor frame.

[0014] Preferably, when the multiple telescopic components are retracted and the conveyor frame is in a vertical position, the stainless steel sheet is positioned by abutting against one side of the stainless steel sheet.

[0015] Preferably, a pressure sensor is also fixedly installed inside the conveying positioning frame. When the conveying frame abuts against one side of the stainless steel sheet, the pressure sensor transmits an electrical signal under pressure to stop the contraction of the multiple telescopic components.

[0016] The beneficial effects of this invention are as follows: 1. The present invention discloses an integrated laser cutting and welding machine for stainless steel sheets. The adjustable distance between the conveying positioning frame and the conveying table allows for positioning of stainless steel sheets of varying widths. After positioning, the irregular end of the stainless steel sheet is held inside the feeding clamping table. The laser processing component moves along multiple axes within the multi-axis moving frame to laser cut the irregular ends of the two stainless steel sheets. The sheets are then conveyed through the conveying table until the flat ends of the two sheets are positioned and joined. Finally, the multi-axis movement of the laser processing component performs laser welding on the two sheets, achieving a butt weld between the two stainless steel sheets with irregular ends. This integrated design automates the process, avoiding the need for manual steps and low efficiency.

[0017] 2. The laser cutting and welding integrated machine for stainless steel thin plates described in this invention, when the stainless steel thin plate is inside the conveyor table, is clamped by conveyor belt components three and two on both sides. At this time, conveyor belt component three abuts against one side of the stainless steel thin plate. The conveyor frame will move slightly inside the conveyor positioning frame, thereby causing the conveyor frame to squeeze the pressure sensor to a certain extent. When the pressure sensor senses the squeezing force to reach a predetermined value, it indicates that the clamping of conveyor belt components three and two has reached the predetermined state. At the same time, the upper and lower sides of the stainless steel thin plate are also clamped by two conveyor belt components one, thereby realizing the positioning of the stainless steel thin plate. When it needs to be conveyed, two conveyor belt components one, three, and two are driven simultaneously to realize the conveying of the stainless steel thin plate. The positioning step is implemented without affecting the continued conveying of the stainless steel thin plate. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1-5 As shown in the embodiment of the present invention, a laser cutting and welding integrated machine for stainless steel sheet includes a machine tool (1) and a multi-axis moving frame (2) installed above the machine tool (1). The laser processing component (3) is installed inside the multi-axis moving frame (2). The laser processing component (3) is used to perform laser cutting and laser welding on the stainless steel sheet. Feeding clamping tables (4) are also fixedly installed on both sides above the machine tool (1). A conveying component (5) is fixedly installed on one side of the feeding clamping table (4). A positioning conveying component (6) is rotatably installed at one end of the conveying component (5). The two feeding clamping tables (4) are located below the multi-axis moving frame (2). The conveying assembly (5) has a conveying cavity (511) inside, and the stainless steel sheet is conveyed inside the conveying cavity (511). The positioning conveying component (6) includes a rotating plate (61) rotatably installed on one side below the conveying table (51) and multiple telescopic components (62) fixedly installed on one side of the rotating plate (61). One end of the multiple telescopic components (62) is fixedly installed with a conveying positioning frame (63).

[0023] Specifically, in this device, when it is necessary to butt weld two stainless steel sheets with irregular ends, the two stainless steel sheets are first inserted into the conveying cavity (511) for conveying. At this time, the irregular ends of the two stainless steel sheets are facing the center of the machine tool (1). Then, the positioning conveyor (6) rotates on one side of the conveying assembly (5). During the rotation of the positioning conveyor (6), multiple telescopic components (62) extend, thereby increasing the distance between the conveying positioning frame (63) and the conveying table (51). The continuous rotation of the positioning conveyor (6) This causes the positioning conveyor (6) to change from a downward state to a horizontal state, meaning that the positioning conveyor (6) and the conveying assembly (5) are at the same horizontal level. Then, through the contraction of multiple telescopic components (62), the distance between the conveying positioning frame (63) and the conveying table (51) is reduced until the structure conveyed by the conveying positioning frame (63) contacts and presses against the stainless steel sheet, correcting the position of the stainless steel sheet inside the conveying cavity (511), thus achieving positioning. The distance between the conveying positioning frame (63) and the conveying table (51) is adjustable and can be used to address different... Stainless steel sheets of the same width are positioned and then transported by the conveyor (51). The irregular end of the positioned stainless steel sheet is placed inside the feeding clamping table (4) and clamped. The laser processing component (3) moves in the multi-axis moving frame (2) to laser cut the irregular end of the two stainless steel sheets, making the irregular end flat. The sheets are then transported by the conveyor (51) and the flat end of the two sheets is positioned and connected. The multi-axis moving of the laser processing component (3) is then used to cut the irregular end of the two sheets. Laser welding is used to weld two stainless steel plates with irregular ends together. The device is automated by integrating the two, avoiding the need for manual steps and low efficiency. The positioning conveyor (6) can accommodate plates of different widths and achieve position positioning, so that the ends are less likely to tilt or deviate during laser cutting. The laser processing component (3) in this device can be integrated with the laser cutting head and the laser welding head, or it can be assembled with both. When a certain laser processing is needed, it is driven by the electrical structure.

[0024] like Figures 2-5 As shown, the inside of the feeding clamping table (4) is provided with a feeding groove (41). Multiple fixed motors (42) are fixedly installed on one side of the feeding clamping table (4). A lower pressure plate (43) is installed below the fixed motor (42) and moves up and down. After the lower pressure plate (43) descends, it cooperates with the bottom side of the feeding groove (41) to clamp the stainless steel sheet.

[0025] Lifting frames (52) are installed at both the upper and lower positions inside the conveying cavity (511), and multiple (53) are installed at both the upper and lower positions of the conveying platform (51).

[0026] The ends of the plurality of (53) facing the conveying cavity (511) all pass through the conveying table (51) and are fixedly connected to the side of the corresponding lifting frame (52). The plurality of (53) are used to drive the two lifting frames (52) to rise and fall inside the conveying cavity (511).

[0027] The lifting frame (52) is internally equipped with a transmission belt component (521). The transmission belt component (521) is driven by the electrical structure inside the lifting frame (52) to perform the conveying work. The closest distance between the transmission belt component (521) inside the same group of lifting frames (52) and the center position of the conveying cavity (511) is less than the closest distance between the center position of the lifting frame (52) and the center position of the conveying cavity (511).

[0028] A strip groove (512) is also provided on one side of the conveyor platform (51). A second transmission belt component (513) is installed inside the strip groove (512). The second transmission belt component (513) is driven by the internal electrical structure of the conveyor platform (51).

[0029] Specifically, when the stainless steel sheet is placed inside the conveying chamber (511), that is, between the two conveyor belt components (521), through the setting of multiple (53), the two lifting frames (52) move towards each other until the stainless steel sheet in the middle position is clamped. At this time, the bottom side of the stainless steel sheet inside the conveying chamber (511) is at the same horizontal height as the bottom side of the feed trough (41). Then, the positioning conveyor (6) rotates and multiple telescopic components (62) extend and retract until the component conveyed by the conveying positioning frame (63) abuts against one side of the stainless steel sheet. At this time, the lifting frame (52) above the inside of the conveying table (51) moves up and no longer tightly clamps the stainless steel sheet in the middle position. As the multiple telescopic components (62) continue to retract, one side of the stainless steel sheet moves towards the second conveyor belt component (513) until both sides of the stainless steel sheet are clamped by the conveyor belt components. The stainless steel sheet is held by the two (513) and the conveying positioning frame (63). Then the lifting frame (52) above the inside of the conveying table (51) descends, and the two lifting frames (52) hold the stainless steel sheet again. At this time, the stainless steel sheet is positioned so that when the stainless steel sheet is conveyed, its irregular end can be cut flat and then welded. When the stainless steel sheet is conveyed into the feed trough (41), the bottom side of the stainless steel sheet and the bottom side of the feed trough (41) are at the same level. As the stainless steel sheet is conveyed, after the irregular end of the stainless steel sheet is in the designated position, the fixed motor (42) drives the lower pressure plate (43) to descend. At this time, the irregular end of the stainless steel sheet is held by the lower pressure plate (43) and the bottom side of the feed trough (41). Then, the subsequent laser cutting and laser processing work is carried out by the multi-axis movement of the laser processing component (3).

[0030] Example 2: Figures 5-6 As shown in the first embodiment, another embodiment of the present invention is as follows: a rotating adjustment shaft (514) is rotatably installed on one side below the conveyor table (51). The rotating adjustment shaft (514) is connected to the rotating plate (61). The rotating adjustment shaft (514) rotates to drive the positioning conveyor (6) to rotate on one side of the conveying assembly (5).

[0031] The conveyor positioning frame (63) is movably installed inside the conveyor frame (631), and the conveyor frame (631) is internally driven by a transmission belt component three (632). The transmission belt component three (632) is driven to perform conveying work through the electrical structure inside the conveyor frame (631).

[0032] When the multiple telescopic components (62) are retracted and the conveyor frame (631) is in a vertical position, the stainless steel sheet is positioned by abutting against one side of the stainless steel sheet.

[0033] A pressure sensor (633) is also fixedly installed inside the conveying positioning frame (63). When the conveying frame (631) abuts against one side of the stainless steel sheet, the pressure sensor (633) transmits an electrical signal under pressure to stop the contraction of the multiple telescopic components (62).

[0034] Specifically, when the stainless steel sheet is inside the conveyor table (51), it is held by the three conveyor belt components (632) and the two conveyor belt components (513) on both sides. At this time, the three conveyor belt components (632) press against one side of the stainless steel sheet. At this time, the conveyor frame (631) will move slightly inside the conveyor positioning frame (63), thereby causing the conveyor frame (631) to squeeze the pressure sensor (633) to a certain extent. When the pressure sensor (633) senses the squeezing force to reach the predetermined value, it indicates that the clamping of the three conveyor belt components (632) and the two conveyor belt components (513) has reached the predetermined state. At the same time, the upper and lower sides of the stainless steel sheet are also held by two conveyor belt components (521), thereby implementing the positioning of the stainless steel sheet. When it needs to be conveyed, the two conveyor belt components (521), the three conveyor belt components (632) and the two conveyor belt components (513) are driven at the same time, thereby realizing the conveying of the stainless steel sheet. While implementing the positioning step, it will not affect the continued conveying of the stainless steel sheet.

[0035] Working principle: In this device, when two stainless steel sheets with irregular ends need to be butt-welded, the two stainless steel sheets are first inserted into the conveying cavity (511) for conveying. At this time, the irregular ends of the two stainless steel sheets are facing the center of the machine tool (1). Then, the positioning conveyor (6) rotates on one side of the conveying assembly (5). During the rotation of the positioning conveyor (6), multiple telescopic components (62) extend, thereby increasing the distance between the conveying positioning frame (63) and the conveying table (51). The continuous rotation of the positioning conveyor (6) causes the positioning conveyor (6) to change from a downward state to a horizontal state. That is, at this time, the positioning conveyor (6) and the conveying assembly (5) are at the same horizontal level. Then, multiple telescopic components extend... The shrinkage of component (62) reduces the distance between the conveying positioning frame (63) and the conveying table (51) until the conveying positioning frame (63) contacts the stainless steel sheet and presses against it, correcting the position of the stainless steel sheet inside the conveying cavity (511), thus achieving positioning. The distance between the conveying positioning frame (63) and the conveying table (51) is adjustable, and positioning can be achieved for stainless steel sheets of different widths. Subsequently, under the continued conveying of the conveying table (51), the irregular end of the positioned stainless steel sheet is inside the feeding clamping table (4) and is clamped. The laser processing component (3) performs laser cutting on the irregular end of the two stainless steel sheets through multi-axis movement inside the multi-axis moving frame (2), making the irregular end... The plates are then flattened and transported via a conveyor (51). The flattened ends of the two plates are positioned and joined together. The laser processing component (3) is then used to perform laser welding on the two plates, allowing the two stainless steel plates with irregular ends to be joined and welded. This device achieves automated operation through integrated design, avoiding the need for manual steps and low efficiency. Furthermore, the positioning conveyor (6) allows for the positioning of plates of different widths, making it less likely for the ends to tilt or shift during laser cutting. The laser processing component (3) in this device can be an integrated design of the laser cutting head and the laser welding head, or it can be an assembly of both. When a laser processing is required, it is driven by an electrical structure. When the stainless steel sheet is inside the conveyor table (51), it is clamped by the three conveyor belt components (632) and the two conveyor belt components (513) on both sides. At this time, the three conveyor belt components (632) abut against one side of the stainless steel sheet. The conveyor frame (631) will move slightly inside the conveyor positioning frame (63), thereby causing the conveyor frame (631) to exert a certain degree of pressure on the pressure sensor (633). When the pressure sensor (633) senses the pressure reaching a predetermined value, it indicates that the clamping of the three conveyor belt components (632) and the two conveyor belt components (513) has reached the predetermined state. At the same time, the upper and lower sides of the stainless steel sheet are also clamped by two conveyor belt components (521), thereby implementing the positioning of the stainless steel sheet. When it needs to be conveyed,Two conveyor belt components, namely 521, 632, and 513, are simultaneously driven to transport the stainless steel sheet. This allows for the continuous transport of the stainless steel sheet without affecting the positioning process.
