Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to welding and cleaning technology, especially an integrated welding and cleaning device. Background Technology

[0002] Workpieces typically require cleaning after welding. Current technologies often employ manual welding, which relies heavily on operator skill, resulting in inconsistent weld quality, excessive slag and spatter, and a cumbersome subsequent cleaning process. Existing cleaning methods utilize contact cleaning, relying on manual labor with tools such as grinding wheels, wire brushes, and sandblasting machines. This mechanical force on the welded workpiece surface can easily damage it or cause the cleaning medium to adhere to the surface, leading to secondary pollution. Furthermore, these methods are susceptible to human and environmental influences, resulting in inconsistent surface quality during batch welding and cleaning, impacting welding efficiency. For example, when welding and cleaning ultra-thin metals (approximately 0.1mm-0.5mm thick), traditional methods are prone to defects such as deformation and abrasion. When the welding and cleaning quality fluctuates, the probability of welding and cleaning defects increases, leading to wasted manpower and resources during repairs and reduced production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an integrated welding and cleaning device to solve the technical problems of manual welding, unstable cleaning quality, and low efficiency in the prior art.

[0004] This utility model provides an integrated welding and cleaning device, including a platform. At least two first support columns are spaced apart along the width direction on one side of the platform, and a first Y-axis linear module is mounted on each first support column. At least two second support columns are spaced apart along the width direction on the other side of the platform, and a second Y-axis linear module is mounted on each second support column. The driving direction of the second Y-axis linear module is parallel to the driving direction of the first Y-axis linear module. The driving ends of the first and second Y-axis linear modules are respectively fixedly connected to the two ends of an X-axis linear module. The driving direction of the X-axis linear module is perpendicular to the first Y-axis linear module. The driving direction of the Y-axis linear module is as follows: the driving end of the X-axis linear module is connected to the Z-axis linear module; the driving direction of the Z-axis linear module is perpendicular to the driving direction of the X-axis linear module and the driving direction of the first Y-axis linear module; the driving end of the Z-axis linear module is connected to a mounting bracket; the mounting bracket is equipped with a laser galvanometer welding device, a laser galvanometer cleaning device, and an air knife device; the laser galvanometer welding device and the laser galvanometer cleaning device are spaced apart along the width direction of the platform; the air knife device and the laser galvanometer welding device are spaced apart along the length direction of the platform; the air knife device includes a fan, a pipe, and a nozzle; the air outlet of the fan is connected to the nozzle through the pipe.

[0005] Furthermore, the X-axis linear module is equipped with a cable chain.

[0006] Compared with existing technologies, this invention offers significant and positive advantages. It can both clean and weld workpieces. By driving the laser galvanometer welding and cleaning devices via an X-axis linear module, a first Y-axis linear module, and a second Y-axis linear module, welding or cleaning can be performed at various points or along a path. Compared to existing manual welding and cleaning methods, laser welding and cleaning offer more stable quality and higher efficiency. Laser cleaning requires no chemical agents or cleaning solutions; the waste generated is primarily solid powder, small in volume, easy to store, recyclable, and easy to remove, thus solving environmental pollution problems. Laser cleaning effectively removes various types of contaminants from the surfaces of various materials, achieving a level of cleanliness unattainable by manual cleaning. It features a small heat-affected zone, minimal deformation, and fast welding and cleaning speeds. No special treatment is required after welding and cleaning.

Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0009] like Figure 1As shown, this utility model provides an integrated welding and cleaning device, including a platform 1. At least two first support columns 2 are spaced apart along the width direction on one side of the platform 1, and a first Y-axis linear module 3 is mounted on each of the first support columns 2. At least two second support columns 4 are spaced apart along the width direction on the other side of the platform 1, and a second Y-axis linear module 5 is mounted on each of the second support columns 4. The driving direction of the second Y-axis linear module 5 is parallel to the driving direction of the first Y-axis linear module 3. The driving ends of the first Y-axis linear module 3 and the second Y-axis linear module 5 are respectively fixedly connected to the two ends of an X-axis linear module 6. The driving direction of the X-axis linear module 6 is perpendicular to the first Y-axis linear module 3. In terms of driving direction, the driving end of the X-axis linear module 6 is connected to the Z-axis linear module 7. The driving direction of the Z-axis linear module 7 is perpendicular to the driving direction of the X-axis linear module 6 and the driving direction of the first Y-axis linear module 3. The driving end of the Z-axis linear module 7 is connected to the mounting bracket 8. The mounting bracket 8 is equipped with a laser galvanometer welding device 9, a laser galvanometer cleaning device 10, and an air knife device. The laser galvanometer welding device 9 and the laser galvanometer cleaning device 10 are spaced apart along the width direction of the platform 1. The air knife device and the laser galvanometer welding device 9 are spaced apart along the length direction of the platform 1. The air knife device includes a fan (not shown in the figure), a pipe (not shown in the figure), and a nozzle 11. The air outlet of the fan is connected to the nozzle 11 through the pipe.

[0010] Furthermore, a drag chain 12 is provided on the X-axis linear module 6.

[0011] Specifically, the linear module, laser galvanometer welding device 9, laser galvanometer cleaning device 10, drag chain 12, fan, nozzle 11 and other parts not described in detail in this utility model adopt known solutions in the prior art, which are already understood by those skilled in the art and will not be repeated here.

[0012] The working principle of this utility model:

[0013] Both the laser galvanometer welding device 9 and the laser galvanometer cleaning device 10 include a fiber laser optical path and a galvanometer system. Their working principle involves transmitting the laser beam generated by the laser through an optical fiber and a beam expander to amplify the beam. After amplification and reshaping, the beam is transmitted to the galvanometer's entrance aperture. The beam is reflected vertically downwards by mirrors inside the galvanometer and then focused onto the workpiece by a field lens. High-energy laser pulses are used to locally heat a small area of ​​the material. The energy of the laser radiation diffuses into the material's interior through heat transfer, achieving both welding and cleaning effects.

[0014] This equipment can both clean and weld workpieces, employing two types of lasers and two galvanometer systems. The laser galvanometer welding device 9 uses a continuous laser with a 30mm galvanometer, capable of withstanding high power and forming a better molten pool for welding. The focusing lens has a focal length of F=420mm. The laser galvanometer cleaning device 10 uses a pulsed laser with a 14mm galvanometer. The galvanometer lens is lighter and can oscillate at high speed, achieving better cleaning results on the surface. Both lasers emit laser light with a wavelength of 1064nm, and the focusing lens has a focal length of F=254mm.

[0015] During operation, the workpiece is manually fixed onto platform 1 using fixtures. After the operator evacuates to a safe area, the laser galvanometer welding device 9 or laser galvanometer cleaning device 10 is moved by the X-axis linear module 6, the first Y-axis linear module 3, and the second Y-axis linear module 5, aligning the center of the workpiece with the center of the galvanometer. The Z-axis linear module 7 then drives the laser galvanometer welding device 9 and the laser galvanometer cleaning device 10 to adjust them to a suitable height. Subsequently, the X-axis linear module 6, the first Y-axis linear module 3, and the second Y-axis linear module 5 drive the laser galvanometer welding device 9 to move to the various points requiring welding, or the X-axis linear module 6, the first Y-axis linear module 3, and the second Y-axis linear module 5 drive the laser galvanometer cleaning device 10 to the various points requiring cleaning. The order of cleaning and welding can be selected according to the actual situation.

[0016] This invention can both clean and weld workpieces. The laser galvanometer welding device 9 and laser galvanometer cleaning device 10 are moved via the X-axis linear module 6, the first Y-axis linear module 3, and the second Y-axis linear module 5, enabling welding or cleaning at various points or along a path. Compared to existing manual welding and cleaning methods, laser welding and cleaning offer stable quality and higher efficiency. Laser cleaning requires no chemical agents or cleaning solutions; the waste material is primarily solid powder, small in volume, easy to store, recyclable, and easy to remove, thus solving environmental pollution problems. Laser cleaning can effectively remove various types of contaminants from the surface of various materials, achieving a level of cleanliness unattainable by manual cleaning. It features a small heat-affected zone, minimal deformation, and fast welding and cleaning speeds. No special treatment is required after welding and cleaning. Its advantages are particularly pronounced for ultra-thin materials (0.1mm-0.5mm), high-hardness materials, high-melting-point materials, and precision materials.
