Description

Technical Field

[0001] The present invention relates to the technical field of the production of notebook metal casings, and particularly relates to an anodic oxidation fixture. Background Art

[0002] Aluminum alloys and magnesium alloys are widely used in the field of notebook casings due to their advantages such as light weight, high strength, and good heat conduction. In order to overcome the defects of aluminum alloys and magnesium alloys in terms of surface hardness, wear resistance, etc. and extend their service life, anodic oxidation surface treatment technology has become an indispensable part of the production of aluminum alloy and magnesium alloy notebook casings. So-called anodic oxidation is a process in which an aluminum alloy and a magnesium alloy form an oxide film on their surfaces under the action of an externally applied current in a corresponding electrolyte and specific process conditions. This oxide film has protective and decorative properties.

[0003] Anodic oxidation requires an anodic oxidation production line. The anodic oxidation production line is actually composed of tanks filled with various electrolytes (such as sulfuric acid, chromic acid, oxalic acid, etc.). Products need to enter the tanks through fixtures. For the upper covers and bottom covers of notebooks, since there are no holes on the surfaces of such products, they cannot be tied to the fixtures. In the prior art, fixtures with grooves are also designed, and the upper covers and bottom covers of notebooks are inserted into the grooves of the fixtures. Designing grooves will result in excessive contact surfaces with the products, and defects will occur at the contact surface positions during the oxidation process. Summary of the Invention

[0004] In view of the above problems, the present invention provides a novel anodic oxidation fixture.

[0005] In order to achieve the above object, the technical solution provided by the present invention is as follows:

[0006] An anodic oxidation fixture includes a hanging rack. A hook is provided at the top of the hanging rack. A plurality of elastic sheet support structures are provided at a position near the middle of the hanging rack. A limiting groove and an outer positioning base are provided at the bottom of the hanging rack. The elastic sheet support structure includes a fixed support hook and an elastic sheet support hook. The fixed support hook includes a polygonal bracket and a first support hook provided on the polygonal bracket. The elastic sheet support hook includes an elastic sheet, a retaining bar, and a limiting bar. An opening is provided at one end of the limiting bar, and the other end is installed on the retaining bar. One end of the elastic sheet is fixed on the retaining bar, and the other end passes through the opening and protrudes. A second support hook is provided on the elastic sheet protruding from the opening.

[0007] Compared with the prior art, the beneficial effect of the present invention lies in:

[0008] An anodic oxidation fixture of the present invention, a support hook is provided on an elastic sheet, and the support hook is propped up and fixed on the inner side of the upper cover or the bottom cover of a notebook by the elastic force of the elastic sheet. The elastic sheet support structure of the present invention can be distributed on the upper and lower sides of the hanger, and multiple products can be hung at one time. By using this fixture, the contact points between the fixture and the products are on the inner side, which does not affect the appearance oxidation, and multiple products can be hung, so the production efficiency is high.

[0014] Referring to Figures 1-5 as shown, an anodic oxidation fixture includes a hanger 1, a hook 2 is provided at the top of the hanger 1, a plurality of elastic sheet support structures are provided at a position close to the middle of the hanger 1, and a limit groove 3 and an outer positioning base 4 are provided at the bottom of the hanger 1; the elastic sheet support structure includes a fixed support hook and an elastic sheet support hook; the fixed support hook includes a polygonal bracket 5 and a first support hook 6 provided on the polygonal bracket 5; the elastic sheet support hook includes an elastic sheet 7, a stop strip 8 and a limit strip 9; one end of the limit strip 9 is provided with an opening 10, and the other end is installed on the stop strip 8; one end of the elastic sheet 7 is fixed on the stop strip 8, and the other end passes through the opening 10 and protrudes; a second support hook 11 is provided on the elastic sheet 7 protruding from the opening 10.

[0015] An anodic oxidation fixture of the present invention is mainly used for notebook housing parts such as the upper cover or the bottom cover of a notebook. Since there are bends at the edges of the upper cover or the bottom cover of the notebook, the design principle of this fixture is to support and fix through the elastic force of the elastic sheet 7 from the bends of the upper cover or the bottom cover of the notebook. The specific principle is as follows:

[0016] The fixture of the present invention is picked up by a manipulator or manually. The hook 2 is for hanging on the anodic oxidation line. The limiting groove 3 provided at the bottom of the hanging rack 1 is mainly used for positioning, and the outer positioning base 4 is mainly for enabling the fixture to be placed stably on the ground. During use, one end of the upper cover or bottom cover of the notebook is first positioned on the first support hook 6 of the fixed support hook by a manipulator or manually, and then the elastic piece 7 is compressed by a manipulator or manually. Since the second support hook 11 is fixed to the elastic piece 7, the second support hook 11 will shift with the compression deformation of the elastic piece 7. It only needs to fix the second support hook 11 to the other end of the upper cover or bottom cover of the notebook to complete the support and fixation of the upper cover or bottom cover of the notebook by the first support hook 6 and the second support hook 11.

[0017] The elastic piece support structure of the present invention can be distributed on the hanging rack in an upper and lower double-sided manner, and multiple products can be hung at one time, with extremely high production efficiency. By using this fixture, the contact points between the fixture and the product are on the inner side and do not affect the appearance, and the anodic oxidation quality is relatively high.

[0018] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the present invention's solution still fall within the protection scope of the present invention.
