[0002] Anodized aluminum is an aluminum product that forms an aluminum oxide layer with a certain thickness on the surface of the aluminum material through anodization. The adhesion of the anodized aluminum layer directly affects the quality of the product.

Providing a device that can change the surface roughness of the aluminum plate has become one of the technical problems that need to be solved urgently. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides a device for improving the adhesion control of anodized film on the surface of an aluminum plate. The laser emitted by a laser is irradiated on the surface of the aluminum plate to be processed to improve the roughness of the surface of the aluminum plate, thereby improving the adhesion of the oxide film. At the same time, the laser emitted by the laser enters the surface of the aluminum plate on a support seat after being reflected by a flexible reflector. Since the reflecting surface of the flexible reflector can be bent, the irradiation area of ​​the laser after being reflected by reflectors with different curvatures changes. Under the condition of the same output light power, the energy of the irradiation area per unit area can be changed, thereby realizing the change of the surface roughness of the aluminum plate. By changing the roughness, the purpose of improving and controlling the adhesion of the oxide film is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the embodiments of the present invention belong. If the definitions set forth in this section are contrary to or otherwise inconsistent with the definitions set forth in the patents, patent applications, published patent applications, and other publications incorporated herein by reference, the definitions listed in this section take precedence over the definitions incorporated herein by reference.

[0022] like Figure 1 As shown, combined Figure 2 The utility model discloses a device for improving the adhesion control of anodized film on the surface of aluminum plate, which comprises: a sealed cabin 1, a support seat 2, a laser 3, a first slide rail 4 and a flexible reflector 5. The support seat 2 is arranged at the inner bottom of the sealed cabin 1, and the first slide rail 4 is fixedly installed on one side surface of the inside of the sealed cabin 1 in the horizontal direction. The laser 3 slides on the first slide rail 4, and the reflective surface of the flexible reflector 5 is arranged toward the bottom of the laser 3. The mirror surface of the flexible reflector 5 can be bent around an axis parallel to the length direction of the first slide rail. The outgoing light of the laser 3 is reflected by the flexible reflector 5 and then emitted to the support seat.

[0023] In the above embodiment, the flexible reflector 5 is used to reflect the laser emitted by the laser 3 to the surface of the aluminum plate installed on the support seat 2, so as to perform laser ablation, impurity removal and roughening treatment on the aluminum plate. The laser 3 moves horizontally on the first slide rail 4 so that the reflected laser can move horizontally on the surface of the aluminum plate in a direction parallel to the first slide rail 4. The surface of the flexible reflector 5 can be bent. During the bending process, the curvature changes, so that the size of the laser spot reflected to the surface of the aluminum plate can be changed. Under the premise that the laser power remains unchanged, the larger the laser spot, the smaller the energy of the spot per unit area. On the contrary, the smaller the laser spot, the larger the energy of the spot per unit area. By changing the surface curvature of the flexible reflector 5, the energy of the spot per unit area reflected to the surface of the aluminum plate can be changed, thereby changing the effect of the laser spot on the surface of the aluminum plate, so that the surface roughness after the effect is different, and different roughness brings different adhesion.

[0024] In some embodiments, the flexible reflector 5 includes a flexible mirror 51, a support block 52, a driving cylinder 53 and a traction rope 54. The support block 52 is fixed on the inner side of the sealed cabin 1 along the horizontal direction. The length direction of the support block 52 is parallel to the length direction of the first slide rail 4. A cylindrical surface 521 is provided on the side of the support block 52 close to the first slide rail 4. The axis of the cylindrical surface 521 is parallel to the first slide rail 4. The back side of the flexible mirror 51 is fixedly connected to the cylindrical surface of the support block 52 at the position of the symmetry axis along the length direction. A driving cylinder 53 is fixed on the side of the support block 52 away from the flexible mirror 51. The driving end of the driving cylinder 53 is fixedly connected to the two sides of the width direction of the flexible mirror through multiple traction ropes 54. When the driving cylinder 53 is extended or retracted, it can drive the flexible mirror 51 to bend and change the curvature.

[0025] In the above embodiments, the support block 52 is used to support the flexible mirror 51. The flexible mirror 51 is a rectangular flat structure, which can maintain a flat structure when not subjected to any external force other than gravity. The drive cylinder 53 can drive the traction rope 54 to pull the two side edges of the flexible mirror 51 when performing telescopic driving, thereby changing the curvature of the surface of the flexible mirror 51, thereby changing the spot size of the reflected laser.

[0026] In some embodiments, the traction rope 54 can adopt a rigid connecting rod, and the two ends of the connecting rod are respectively hinged to the edge of the flexible mirror 51 and the driving end of the driving cylinder 53. At this time, when the driving cylinder 53 is telescopically driven, it can not only make the flexible mirror 51 bend toward the side close to the driving cylinder 53, but also bend toward the side away from the driving cylinder 53.

[0027] In some embodiments, a support plate 55 is also included, and the support plate 55 is fixed at the driving end of the driving cylinder 53. The plane where the support plate 55 is located is perpendicular to the driving direction of the driving cylinder 53. Both side edges of the support plate 55 along the width direction are parallel to both side edges of the flexible mirror 51 along the width direction. The support plate 55 and the same side of the flexible mirror 51 are fixedly connected by multiple traction ropes 54 of the same length and parallel to each other.

[0028] In the above embodiments, the support plate 55 is used to match the size of the flexible mirror 51. When the flexible mirror 51 is not subjected to external force, its plane is parallel to the plane of the support plate 55, and the support plate 55 and the flexible mirror 51 are both rectangular. A plurality of traction ropes 54 are respectively connected to both sides of the support plate 55 in the width direction, and one end of the traction rope 54 away from the support plate 55 is connected to both ends of the flexible mirror 51 in the width direction. Figure 2 As shown, when the driving cylinder 53 reciprocates linearly, it drives the support plate 55 to reciprocate linearly, so that the traction ropes 54 on both sides are pulled synchronously, and finally the two side edges of the flexible mirror 51 along the width direction are pulled synchronously, realizing the change of the curvature of the flexible mirror 51.

[0029] In some embodiments, a second slide rail 6 is further included, and two second slide rails 6 are horizontally mounted on two adjacent sides of the side where the first slide rail 4 is located, and the two opposite sides of the flexible reflector 5 are respectively slidably mounted on the two second slide rails 6. In the above embodiments, the second slide rail 6 is provided to enable the flexible reflector 5 to perform a linear reciprocating motion along the second slide rail 6. Preferably, the length direction of the second slide rail 6 is perpendicular to the length direction of the first slide rail 4, and at this time, the light spot reflected to the surface of the aluminum plate can be moved within the plane where the aluminum plate is located.

[0030] In the above embodiments, preferably, a slider is provided on the second slide rail 6 , and both ends of the support block 52 of the flexible reflector 5 along the length direction are respectively fixed on the sliders of the two second slide rails 6 .

[0031] In some embodiments, an air blowing pipe 7 is further included. The air blowing pipe 7 is arranged inside the sealed cabin 1 , and an air outlet end of the air blowing pipe 7 is arranged toward the support seat 2 .

[0032] In the above embodiment, the air blowing pipe 7 is used to blow air to the surface of the aluminum plate mounted on the support seat 2, so that the solid particle vapor generated during the laser ablation roughening process can be quickly removed to avoid affecting the normal irradiation of the laser.

[0033] In some embodiments, a negative pressure fan 8 is further included. The negative pressure fan 8 is disposed on a surface of the sealed cabin 1 opposite to the air blowing pipe 7 , and the negative pressure fan 8 is connected to both the inside and outside of the sealed cabin 1 .

[0034] In the above embodiments, the negative pressure fan 8 is used to discharge dust particles in the sealed cabin 1 , and cooperates with the air blowing pipe 7 to quickly discharge suspended particles generated by laser ablation, making the environment in the sealed cabin 1 cleaner.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
