Description

Technical Field

[0001] This invention relates to the field of laser welding technology, and more specifically, to a laser welding processing device. Background Technology

[0002] Laser welding is a process that uses a high-energy-density laser beam to irradiate the surface of a workpiece, melting the material and forming a weld. It features non-contact and localized heating. Laser welding is widely used due to its advantages such as a small heat-affected zone, a high weld depth-to-width ratio, and a low risk of deformation and cracking.

[0003] In related technologies, existing laser welding equipment typically uses rigid clamping components to hold irregularly shaped workpieces. However, it's difficult to achieve balanced pressure at each clamping point, leading to excessive localized stress and potential damage to the workpiece. Furthermore, for workpieces requiring welding at both the top and bottom, the workpiece is usually flipped after top welding before welding the bottom. Since the workpiece is not fully welded and its structure is not yet stable, flipping it can easily damage it. Therefore, we propose a laser welding processing device. Summary of the Invention

[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0029] like Figures 1-9 As shown, a laser welding processing device includes: a welding head 1, a processing table 2, a space adjustment component 3, and two sets of clamping modules 4. The welding head 1 and its supporting equipment are existing technologies; in this application, the welding head 1 is simplified. The processing table 2 mainly serves as a mounting and support structure, providing a carrier for mounting and supporting corresponding components. The space adjustment component 3 is mainly used to adjust the position of the welding head 1, facilitating welding of multiple positions on the workpiece. The two sets of clamping modules 4 can clamp irregularly shaped workpieces, thereby enabling better welding of the workpiece.

[0030] Specifically, such as Figure 1 , 2 and Figure 5 As shown, the processing table 2 includes a base 22, a top plate 21, and a connecting seat 23. The top plate 21 is positioned above the base 22 and can be arranged parallel to the base 22. The top and bottom of the connecting seat 23 are fixedly connected to the top plate 21 and the base 22 respectively, thereby connecting the base 22 and the top plate 21, making the structure of the processing table 2 more robust and stable.

[0031] In addition, a processing area is provided on the top plate 21, which is mainly used to place the workpiece to be welded. A movable hole 211 is provided on the top plate 21. In the vertical direction, the cross-sectional shape of the movable hole 211 can be a rectangular structure. A support plate 212 is slidably connected within the movable hole 211. The support plate 212 mainly serves to support the workpiece. The support plate 212 can selectively move to the processing area; that is, it can move to the processing area to support the workpiece, or it can move out of the processing area to expose the bottom of the workpiece, thus facilitating welding of the bottom of the workpiece. It should be noted that one side of the movable hole 211 has an opening that communicates with the outside. This allows the welding head 1 and the space adjustment component 3 to avoid interference when the space adjustment component 3 moves the welding head 1.

[0032] In addition, such as Figure 1 and Figure 2As shown, the space adjustment component 3 is mounted on the base 22. The space adjustment component 3 includes an arc-shaped connecting plate 31, a position adjustment component 32, and a drive component 33. The opening of the connecting plate 31 faces the processing area. The position adjustment component 32 is connected to both the connecting plate 31 and the welding head 1, and is used to adjust the welding angle of the welding head 1 in the vertical plane and the distance between the welding head 1 and the processing area. The drive component 33 is connected to the connecting plate 31 to drive the welding head 1 to rotate around the processing area.

[0033] Specifically, such as Figure 2 As shown, the position adjustment assembly 32 includes: a fixed plate 321, a motor 322, and a cylinder 323. The motor 322 is fixedly connected to the connecting plate 31. The output shaft of the motor 322 slides through the connecting plate 31 and is fixedly connected to the fixed plate 321. The fixed plate 321 can be L-shaped, or other suitable structures. The fixed end of the cylinder 323 is fixedly connected to the fixed plate 321, and the telescopic end of the cylinder 323 is fixedly connected to a welding seat, which is fixedly connected to the welding head 1. The axis of the output shaft of the motor 322 is parallel to the axis of the connecting plate 31 and is horizontal. The axial direction of the output shaft of the motor 322 is perpendicular to the telescopic direction of the cylinder 323, which telescopically extends and retracts along the radial direction of the corresponding circle on the connecting plate 31.

[0034] In the initial state of use, the welding head 1 is positioned above the top plate 21, and both the welding port orientation of the welding head 1 and the cylinder 323 can be vertically aligned, facilitating welding of the upper part of the workpiece. First, the support plate 212 is moved to the processing area, and the workpiece is placed on it. Then, the workpiece is clamped and fixed using two sets of clamping modules 4. The cylinder 323 can adjust the distance between the welding head 1 and the workpiece, thus enabling welding. When the welding angle of the welding head 1 needs to be adjusted individually, the motor 322 is activated. The motor 322 drives the fixed plate 321 to rotate. The rotation of the fixed plate 321 is transmitted through the cylinder 323 and the welding seat, thereby causing the welding head 1 to rotate in the vertical plane, allowing for individual adjustment of the welding angle of the welding head 1.

[0035] In addition, such as Figure 2As shown, the drive assembly 33 includes: a cross module 331, a mounting base 332, a second motor 333, a drive plate 334, and multiple connecting pipes 335. The cross module 331 is fixedly connected to the base 22, and the mounting base 332 is fixedly connected to the slider of the cross module 331. It should be noted that the cross module 331 and the slider are existing technologies. The cross module 331 is used to drive the mounting base 332 to move in a horizontal plane. The drive plate 334 has a fan-shaped structure with the same radius as the connecting plate 31. The drive plate 334 can be parallel to and concentrically arranged with the connecting plate 31. The mounting base 332 can be an upward-opening U-shaped structure. The second motor 333 is fixedly connected to the mounting base 332, and the output shaft of the second motor 333 is fixedly connected to the center of the drive plate 334. The axis of the connecting pipe 335 is parallel to the axes of the connecting plate 31 and the drive plate 334, and the two ends of the connecting pipe 335 are fixedly connected to the connecting plate 31 and the drive plate 334 respectively.

[0036] In use, the cross module 331 can adjust the position of the welding head 1 on the horizontal plane through the mounting base 332, drive plate 334, connecting pipe 335, connecting plate 31 and position adjustment component 32, so that the welding head 1 can weld to multiple positions of the workpiece.

[0037] When the position adjustment component 32 alone cannot meet the welding requirements, the position of the welding head 1 can be adjusted by using the drive component 33 in conjunction with the position adjustment component 32.

[0038] For example, when welding the bottom of a workpiece is required, the two sets of clamping modules 4 maintain a fixed clamping position on the workpiece, and the support plate 212 is moved outside the processing area, exposing the bottom of the workpiece. Then, motor 233 is started, which drives the drive plate 334 to rotate. The rotation of the drive plate 334, transmitted through multiple connecting pipes 335, drives the connecting plate 31 to rotate. Through the position adjustment component 32, the welding head 1 can be rotated around the processing area. When the welding head 1 is rotated to a suitable position below the processing area, motor 233 is stopped, and the position of the welding head 1 is then adjusted a second time using the position adjustment component 32, thus achieving welding of the bottom of the workpiece. It should be noted that the position of the rotation center of the drive plate 334 in the horizontal plane can be flexibly adjusted using the cross module 331.

[0039] In addition, such as Figure 1 , Figures 2-7As shown, two sets of clamping modules 4 are symmetrically arranged on both sides of the processing area. Each clamping module 4 includes multiple clamping components 41, which are evenly distributed in a vertical plane. For example, in this application, each clamping module 4 may include six clamping components 41, arranged in two rows on the vertical plane, with three components in each row. The specific number can be set according to the actual working conditions. This arrangement allows for flexible selection of the number of clamping components 41 based on the volume of the workpiece, making it suitable for workpieces of various sizes and providing greater flexibility. For example, for smaller workpieces, only the two bottom opposing clamping components 41 may be needed.

[0040] Specifically, the clamping assembly 41 includes: an air inlet pipe 412, a fixed base 413, multiple clamping tubes 414, and multiple retractable clamping rods 411 for clamping the workpiece surface. Each clamping tube 414 corresponds one-to-one with a clamping rod 411, and the retractable clamping rod 411 means that the clamping rod 411 can slide within the corresponding clamping tube 414. An air chamber 4131 is formed within the fixed base 413. One end of the air inlet pipe 412 is fixedly connected to the side of the fixed base 413 furthest from the processing area, and the air inlet pipe 412 communicates with the interior of the air chamber 4131. The other end of the air inlet pipe 412 communicates with an external air source, allowing the external air source to fill the air chamber 4131 with air through the air inlet pipe 412. Multiple clamping tubes 414 are evenly and fixedly connected to the side of the fixing seat 413 away from the air inlet pipe 412, and all the clamping tubes 414 communicate with the interior of the air chamber 4131. The axial direction of the clamping tubes 414 is the same as the axial direction of the connecting plate 31. For example, in this application, the clamping tubes 414 on each fixing seat 413 can be arranged in five rows and eight columns, and the specific number can be set according to the actual working conditions. Multiple clamping tubes 414 correspond one-to-one with multiple clamping rods 411. One end of the clamping rod 411 is slidably connected inside the clamping tube 414, and a spring 415 is provided between one end of the clamping rod 411 and the bottom of the clamping tube 414. The two ends of the spring 415 can be fixedly connected to one end of the clamping rod 411 and the bottom of the clamping tube 414, respectively. It should be noted that the bottom fixing seat 413 is fixedly connected to the top plate 21, and the upper fixing seat 413 is fixedly connected to the top of the adjacent lower fixing seat 413.

[0041] In use, the workpiece is first placed on the support plate 212 in the processing area. Then, the corresponding number of clamping components 41 are activated according to the actual working conditions. The activation steps of the clamping components 41 are as follows: an external air source is activated to fill the air chamber 4131 with air through the air inlet pipe 412. The air inside the air chamber 4131 then enters the clamping tube 414, which in turn pushes the clamping rods 411 inside the clamping tube 414 toward the workpiece. At this time, the corresponding spring 415 is stretched. Since the surface of the workpiece is usually irregular, the contact time between the multiple clamping rods 411 and the workpiece is also different. When some clamping rods 411 first contact the surface of the workpiece, the air can no longer push the clamping rods 411 that have already contacted the workpiece to move. The air in the air chamber 4131 will continue to fill the corresponding clamping tubes 414 that have not yet contacted the workpiece with air until the corresponding clamping rods 411 also contact the corresponding workpiece surface, thereby realizing the clamping of irregularly shaped workpieces. After processing is completed, the air in the air chamber 4131 and the clamping tube 414 is discharged through the air inlet pipe 412, and the clamping rod 411 will return to its original position under the restoring force of the spring 415.

[0042] The workpiece is clamped by using air to move the clamping rods 411. In this way, the multiple clamping rods 411 can adaptively adjust their respective extension lengths so that the tops of all the clamping rods 411 together form a contour that matches the shape of the workpiece surface, thereby better clamping the workpiece.

[0043] In addition, the compressed air from the external air source creates a relatively uniform pressure field within the air chamber 4131, and this pressure can be transmitted approximately equally to each clamping rod 411. This reduces the possibility of excessive local stress on the workpiece surface, effectively protecting the workpiece surface and preventing clamping, indentation, or deformation.

[0044] Furthermore, the other end of the clamping rod 411 can be hemispherical and made of rubber. The hemispherical structure and rubber material can act as a buffer, avoiding hard contact between the clamping rod 411 and the workpiece, thereby protecting the workpiece.

[0045] In addition, such as Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the laser welding equipment also includes a power assembly 5, which provides power for the movement of the support plate 212. It should be noted that the length direction of the moving hole 211 can be perpendicular to the axis of the connecting plate 31.

[0046] The power assembly 5 includes a motor 51, a screw 52, ​​a nut seat 53, and two mounting plates 54. The two mounting plates 54 are positioned opposite each other and fixedly connected to the bottom of the top plate 21. Both ends of the screw 52 are rotatably connected to the two mounting plates 54 respectively. One end of the screw 52 extends to the outside of the corresponding mounting plate 54 and is fixedly connected to the output shaft of the motor 51. The nut seat 53 is threaded onto the screw 52 and fixedly connected to the bottom of the support plate 212. The screw 52 is horizontally oriented and can be perpendicular to the axial direction of the clamping rod 411. The motor 51 is fixedly connected to the top plate 21. It should be noted that the motor 51 can be positioned near the side of the moving hole 211 that communicates with the outside, and the screw 52 can be positioned on one side of the moving hole 211.

[0047] In use, when the position of the support plate 212 needs to be adjusted, the motor 3 51 is started. The motor 3 51 drives the screw 52 to rotate, and the rotation of the screw 52 causes the nut seat 53 to move along the axial direction of the screw 52. Since the nut seat 53 is fixedly connected to the bottom of the support plate 212, the nut seat 53 can drive the support plate 212 to move along the axial direction of the screw 52, ​​that is, drive the support plate 212 to slide within the moving hole 211, thereby allowing the support plate 212 to selectively move to the processing area to support the workpiece.

[0048] In addition, such as Figure 1 , Figure 2 , Figure 4 , Figure 8 and Figure 9 As shown, the base 22 has a collection chamber 221 inside, and an air pump 6 is fixedly installed on the base 22, communicating with the collection chamber 221. The base 22 also has a feed hole 222 communicating with the collection chamber 221. The connecting plate 31 has a first dust suction chamber 311 inside, and a dust suction hole 312 communicating with the first dust suction chamber 311 is located on the side of the connecting plate 31 facing the processing area. The drive plate 334 has a second dust suction chamber 3341 inside, and a discharge hole 3342 communicating with the second dust suction chamber 3341 is also provided on the drive plate 334. The second dust suction chamber 3341 communicates with the collection chamber 221; specifically, the discharge hole 3342 and the feed hole 222 can be connected by a flexible hose. The two ends of the connecting pipe 335 are respectively connected to the first dust suction chamber 311 and the second dust suction chamber 3341. The collection chamber 221 is mainly used to absorb dust generated during the welding process.

[0049] When in use, when the welding head 1 is working, the air pump 6 is started. The air pump 6 can draw the air out of the collection chamber 221, thereby creating a negative pressure in the collection chamber 221. Since the first dust suction chamber 311 is connected to the collection chamber 221 in sequence through the connecting pipe 335 and the second dust suction chamber 3341, under the action of air pressure, some of the dust splashed during the welding process can be sucked into the first dust suction chamber 311 through the dust suction hole 312, and then input into the collection chamber 221 for collection through the connecting pipe 335, the second dust suction chamber 3341 and the hose.

[0050] It should be noted that a detachable door panel can be installed on the base 22. When the equipment is not in operation, the door panel can be opened to facilitate the collection of dust in the collection chamber 221.

[0051] As an optional embodiment, such as Figure 9 As shown, in the horizontal direction, along the direction perpendicular to the axis of the connecting plate 31, the cross-sectional shape of the suction hole 312 is a trumpet shape, with the side with the smaller opening located inside the suction chamber 311 and the side with the larger opening located outside the suction chamber 311. This allows external dust to more easily enter the suction chamber 311 through the suction hole 312 while preventing internal dust from falling out of the suction hole 312, thus enabling better dust collection.

[0052] As an optional embodiment, such as Figure 1 and Figure 8 As shown, the base 22 has multiple filter holes 223 that communicate with the collection chamber 221. In the vertical direction, the multiple filter holes 223 correspond to the processing area. When welding the bottom of the workpiece, the design of the filter holes 223 can draw some of the dust that falls under gravity into the collection chamber 221, thereby further collecting the dust.

[0053] As an optional embodiment, such as Figure 1 , Figure 2 and Figure 8 As shown, the connecting seat 23 can be located on the side away from the drive assembly 33. In the vertical direction, the cross-sectional structure of the connecting seat 23 can be L-shaped, with multiple filter holes 223 located in the area corresponding to the included angle of the connecting seat 23. The L-shaped design of the connecting seat 23 can seal the two adjacent sides between the top plate 21 and the base 22, thereby reducing dust diffusion and improving environmental friendliness when welding the bottom of the workpiece.

[0054] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
