Description

Technical Field

[0001] This utility model relates to the field of laser cleaning technology, and in particular to a stator laser cleaning device. Background Technology

[0002] Welding is a critical process in stator manufacturing. However, after welding, weld slag, spatter, and other deposits often remain in the weld area, resulting in an uneven surface that fails to meet the precision requirements of subsequent assembly and operation. Therefore, non-contact laser cleaning is typically chosen. This technology uses a high-energy laser beam to selectively remove surface deposits without damaging the workpiece substrate, effectively addressing the challenge of cleaning uneven surfaces. However, in related technologies, the positioning and rotation of the stator workpiece during laser cleaning usually rely on manual operation. This operation mode is not only inefficient but also makes it difficult to ensure that the laser beam maintains the optimal processing angle with complex curved surfaces, easily leading to uneven cleaning and hindering the large-scale application of this process in automated production lines.

[0022] This utility model proposes a stator laser cleaning device 1000.

[0023] Please see Figure 2In one embodiment of this utility model, the stator laser cleaning equipment 1000 includes a cabinet 1, a drive assembly 2, a clamping assembly 3, a laser cleaning assembly, and a control module 6; the drive assembly 2 is located on one side of the cabinet 1 and has a rotatable output end; the clamping assembly 3 is located at the output end of the drive assembly 2 and is used to clamp the workpiece; the laser cleaning assembly is located in the cabinet 1 and its working end faces the clamping assembly 3; the control module 6 is located inside the cabinet 1, and the drive assembly 2, the clamping assembly 3, and the laser cleaning assembly are all electrically connected to the control module 6.

[0024] The drive assembly 2 is fixedly installed on one side of the cabinet 1 and has a rotary motion output end that can be precisely controlled. The clamping assembly 3 is set on this output end. The cooperation between the clamping assembly 3 and the drive assembly 2 realizes the automatic positioning and clamping of the workpiece, and at the same time can drive the workpiece to rotate precisely and continuously.

[0025] The working end of the laser cleaning component faces the workpiece area held by the clamping component 3. When the driving component 2 drives the workpiece to rotate, the laser beam emitted by the laser cleaning component can scan and clean the outer surface of the workpiece.

[0026] The control module 6 is located inside the cabinet 1 and is electrically connected to the drive assembly 2, the clamping assembly 3 and the laser cleaning assembly via cables.

[0027] In the technical solution of this utility model, the workpiece is automatically positioned and clamped by the cooperation of the clamping component 3 and the driving component 2. At the same time, under the control of the control module 6, the workpiece is laser cleaned by the laser cleaning component, which improves the cleaning efficiency.

[0028] For details, please refer to Figure 3In one embodiment of this utility model, the driving assembly 2 includes a first driving module 21, a second driving module 22, and a rotary motor 23. The first driving module 21 is located on one side of the cabinet 1. The first driving module 21 drives the second driving module 22 to move along a first direction, and the second driving module 22 drives the rotary motor 23 to move along a second direction. The clamping assembly 3 is located at the output end of the rotary motor 23. The first direction is vertical, and the second direction is horizontal. Through the cooperation of the first driving module 21 and the second driving module 22, the spatial position of the clamped workpiece in a two-dimensional plane can be precisely adjusted, thus quickly adapting to workpieces of different diameters and heights. When changing product specifications, there is no need for manual adjustment of the clamps or laser head; simply calling the corresponding program through the control module 6 automatically positions the workpiece's rotation center within the optimal focal plane for laser cleaning, greatly improving the equipment's versatility. After the equipment is started, the control module 6 first controls the first drive module 21 and the second drive module 22 to move the clamping assembly 3 to a convenient position for loading the workpiece. After the workpiece is clamped, the control module 6 drives the workpiece to the cleaning position according to the preset program. Subsequently, the rotary motor 23 drives the workpiece to rotate at a constant speed. At the same time, the first drive module 21 and / or the second drive module 22 can perform interpolation movements according to the cleaning requirements of the workpiece, so that the laser beam can cover the entire surface to be cleaned.

[0029] Furthermore, in one embodiment of this utility model, the clamping assembly 3 includes a driving member 31 and two clamping arms. The driving member 31 is located at the output end of the driving assembly 2, and the two clamping arms are located on the driving member 31. The driving member 31 drives the two clamping arms to move closer to or further away from each other. The driving member 31 can be a double-acting cylinder, hydraulic cylinder, or electric lead screw slide, etc., capable of providing linear thrust. The two clamping arms are symmetrically arranged on the driving member 31. When the driving member 31 is working, it synchronously drives the two clamping arms to move closer to or further away from each other along a linear trajectory, thereby achieving the clamping and releasing of the workpiece. Moreover, the synchronous opposite or backward movement of the two clamping arms enables them to automatically find and clamp the center of symmetry of the workpiece, which ensures that the rotation center of the workpiece always coincides with the rotation axis of the driving assembly 2.

[0030] Specifically, in one embodiment of this utility model, please refer to... Figure 3The clamping arm includes a connecting block 32 and two rods 33. The connecting block 32 is located on the driving member 31, and the two rods 33 are spaced apart on the connecting block 32. The connecting block 32 serves as the base of the clamping arm and is directly connected to the driving member 31, transmitting the power of the driving member 31 to the entire clamping arm. The two rods 33 are spaced apart and fixed parallel to the connecting block 32. The two rods 33 are the actuating components that directly contact the workpiece surface and apply clamping force. When the two spaced rods 33 contact the workpiece, they naturally form a stable support plane. For cylindrical or shaft-like workpieces of a certain length, such as stators, this two-point contact method can effectively resist the vibration or overturning moment that may be generated during the rotation of the workpiece, ensuring a smooth machining process.

[0031] Furthermore, in one embodiment of this utility model, a silicone sleeve is fitted onto the rod 33. Precision workpieces such as stators are extremely sensitive to scratches. Direct clamping with the metal rod 33, under immense clamping force, easily leaves indentations or scratches on the workpiece surface, causing secondary damage. The silicone sleeve, as a soft and elastic material, has a large contact area, a high surface friction coefficient, and a hardness far lower than that of metal workpieces. While providing sufficient clamping force, it can evenly distribute pressure, avoiding stress concentration and protecting the workpiece surface.

[0032] Specifically, in one embodiment of this utility model, please refer to... Figure 2 and Figure 3 The laser cleaning assembly includes a laser 4 and a laser cleaning head 5. The laser 4 is housed inside a cabinet 1, and the laser cleaning head 5 is located on one side of the cabinet 1, facing the clamping assembly 3. The laser 4 and laser cleaning head 5 are connected via optical fiber. The laser 4, as the laser source, is fixedly installed inside the cabinet 1 and is responsible for generating high-energy laser light of a specific wavelength, power, and frequency. The laser cleaning head 5 is fixed to one side of the cabinet 1 by a bracket, with its light output facing the workpiece on the clamping assembly 3, and is connected to the laser 4 via optical fiber. This design makes full use of the internal space of the cabinet 1, resulting in a compact and neat overall structure. Furthermore, the core light source is physically isolated from the processing area where vibration or impact may occur, reducing the impact of external interference on the stability of the laser 4.

[0033] Furthermore, in one embodiment of this utility model, please refer to... Figure 1The stator laser cleaning equipment 1000 also includes a light shield 7, which is located on one side of the cabinet 1. The working ends of the drive assembly 2 and the laser cleaning assembly are located inside the light shield 7. The light shield 7 is a closed or semi-closed enclosure made of metal or high-density engineering plastic, fixedly installed on one side of the cabinet 1. The dimensions of the light shield 7 are designed to completely accommodate the output end of the drive assembly 2, the clamping assembly 3, and the working end of the laser cleaning assembly within its internal space. High-energy laser beams and the diffuse reflection light reflected and scattered on the workpiece surface pose a potential risk of permanent damage to human eyes and skin. The light shield 7 constitutes a physical barrier, strictly confining the laser within the enclosure, achieving complete enclosure of the laser processing area, and eliminating the risk of accidental laser irradiation to operators or other personnel present.

[0034] Specifically, in one embodiment of this utility model, please refer to... Figure 1 The top of the light-blocking cover 7 is equipped with an exhaust port 71. The exhaust port 71 is a connecting flange or interface for connecting to an external centralized dust collection system or a standalone fume purifier. During laser cleaning, contaminants (such as metal oxides, paint powder, and oil vapor) are instantly vaporized or stripped away by the laser, generating a large amount of harmful fumes and fine particulate matter. If these fumes accumulate inside the light-blocking cover 7, they will contaminate the protective lens of the laser cleaning head 5, reducing its light transmittance and even damaging optical components. Active extraction through the top exhaust port 71 creates a stable negative pressure airflow inside the cover, capturing and expelling the generated fumes immediately, effectively protecting the lifespan and operational stability of the laser cleaning components.

[0035] Furthermore, in one embodiment of this utility model, please refer to... Figure 3 The stator laser cleaning equipment 1000 also includes a mounting plate 8, which is located on one side of the cabinet 1, and the drive assembly 2 is mounted on the mounting plate 8. The mounting plate 8 is a metal plate with sufficient rigidity and flatness, which is fixedly installed on one side of the cabinet 1 by bolts or welding. The side wall area of ​​the cabinet 1 is relatively large, and its local flatness may have slight deviations. The mounting plate 8 provides a precise mounting reference surface, which is beneficial for the high-precision positioning of the drive assembly 2.

[0036] Specifically, in one embodiment of this utility model, please refer to... Figure 1 Along the perimeter of the cabinet 1, multiple cabinet doors 11 are provided. Specifically, except for the side where the drive assembly 2 and mounting plate 8 are fixedly installed, each of the other three sides has an independent cabinet door 11. By providing cabinet doors 11 on the three sides of the cabinet 1, a comprehensive maintenance access is formed; when needed, inspection, replacement, or debugging can be performed directly by opening the nearest cabinet door 11, shortening maintenance time and reducing labor intensity.

[0037] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
