AI Technical Summary
In the coating process, the hook will be insulated after electrophoresis, resulting in poor conductivity in subsequent painting processes and affecting the efficiency of the entire coating process. To solve this problem, the current practice is to frequently polish the hooks. Although they can restore conductive performance, they are time-consuming and labor-intensive and increase maintenance costs.
A cathodic oxidation hanger is designed. The hanging end of the hook has a tip, forming a point contact structure, which can automatically pierce the insulating layer of the electrophoretic paint layer, reducing or eliminating the need for pre-polishing of the hook. In addition, the second hook forms a surface contact structure with the product, providing sufficient support and stability and simplifying the hanging process.
Through this design, the speed and work efficiency of product hanging are significantly improved, the cost increase caused by frequent maintenance of hooks is reduced, and the difficulty of operation is reduced.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of oxidation hangers, and in particular relates to a cathode oxidation hanger. Background Art
[0002] The coating process mainly includes two parts, electrophoresis and spray painting. However, after the hanger is electrophoresed, its hook will be insulated by the electrophoretic paint. After spray painting, the hanger and the hook will be covered with a layer of paint (i.e., insulating layer) to make the hook and the hanger more insulated. The existence of this insulating layer will affect the conductivity of the hook in the subsequent process. If it enters the spray painting process directly without treatment, it may cause poor conductivity between the hanger and the product to be painted, thus affecting the efficiency of the entire coating process.
[0003] In order to ensure product quality and production efficiency, the current practice is usually to polish and clean all the hooks of the hanger before hanging the product to ensure that the metal body of the hook is exposed to restore good conductivity. However, this frequent polishing operation is not only time-consuming and labor-intensive, reducing the hanging efficiency, but also increases the cost of hanger maintenance, because frequent mechanical wear and chemical corrosion require regular repair and replacement. Utility Model Content
[0004] The utility model aims at the above problems existing in the prior art and proposes a cathode oxidation hanger which can reduce the grinding hook time and improve the hanging efficiency.
[0005] The utility model can be realized through the following technical solutions:

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.
[0026] like Figure 1-3 As shown, the utility model provides a cathode oxidation hanger, comprising:
[0027] Hanging frame 100;
[0028] The hanging assembly is provided with at least one group on the hanging frame 100, and the hanging assembly includes a first hanging rod 110 and a second hanging rod 120 installed on the hanging frame 100, wherein:
[0029] The first hanging rod 110 is equipped with a plurality of first hooks 111, and the second hanging rod 120 is equipped with a plurality of second hooks 121, and both ends of the product are hung on the first hooks 111 and the second hooks 121 respectively;
[0030] The hanging end of the first hook 111 has a pointed portion 1111, and a point contact structure is formed between the hanging end of the product and the first hook 111 through the pointed portion 1111. Such a design principle is based on the fact that in the cathode electrophoresis process, although the overall voltage is high, the current density is low, and only a small contact area is needed to ensure good conductivity, so that the surface of the product is evenly affected by the electric field and completes the electrophoretic coating.
[0031] In addition, the shape design of the tip 1111 of the first hook 111 is also conducive to automatically piercing the insulating layer of the electrophoretic paint layer formed during the product hanging process. In this way, even if the paint layer is attached to the surface of the hanger after the electrophoretic or painting process, it does not need to be manually polished and removed in advance, thereby significantly improving the speed and work efficiency of product hanging and reducing the cost increase caused by frequent maintenance of the hook.
[0032] Preferably, the first hook 111 is installed on the front and rear surfaces of the first hanging rod 110, and the second hook 121 is installed on the front and rear surfaces of the second hanging rod 120, so that the front and rear surfaces of the hanging frame 100 are both hanging surfaces, thereby improving the space utilization of the hanger.
[0033] Preferably, the first hook 111 is arranged in a straight rod-shaped structure, and the hanging end of the first hook 111 is bent to the side to form a first bending portion 1112, and the end of the first bending portion 1112 is arranged as a tip 1111, and the product is clamped by the first bending portions 1112 of each of the two first hooks 111, and a point contact structure is formed between the tip 1111 of the first bending portion 1112 and the product. This point contact method meets the requirement that a small contact area required for cathode electrophoresis can achieve good conductivity, and at this time, the first hook 111 is in close contact with the product, thereby ensuring the stability of the product after hanging.
[0034] Preferably, the second hook 121 is arranged in a U-shaped structure and is connected to the second hanging rod 120 through fasteners. The hanging end of the second hook 121 is bent to the side to form a second bent portion 1211. Similarly, the product is clamped by the two second bent portions 1211 of the second hook 121.
[0035] Among them, a surface contact structure is formed between the second bent portion 1211 and the product, that is, before hanging, the second hook 121 needs to be polished, and the purpose of this surface contact design is that when the operator performs the product hanging operation, first insert the second hook 121 with a U-shaped opening from one side of the product, then smoothly slide the product to a proper position along the length direction of the product, and finally hang the other end of the product on the tip 1111 of the first hook 111 to form a point contact;
[0036] Since the second hook 121 has a larger surface contact area with the product, it can provide sufficient support and stability, making it easy for operators to accurately and quickly position the product during the hanging process, thereby reducing the difficulty of operation and improving work efficiency.
[0037] Preferably, a baffle 130 is installed on the top of any group of hanging components, and both ends of the baffle 130 are connected to the hanging frame 100, that is, there is a baffle 130 between two adjacent groups of hanging components, wherein the baffle 130 located between the two groups of hanging components can absorb the paint dripping from the product to prevent the lower end of the product from dripping, and the baffle 130 located at the upper end of the hanging component can prevent the paint on the other hanging surface of the hanger from blowing over and causing the upper end of the product to drip.
[0038] Preferably, a support frame 140 is provided at the bottom of any group of hanging components. The support frame 140 is mounted on the outside of the hanging frame 100 and connected to the hanging frame 100. Specifically, when the product is hung, the entire hanger is in a sideways state. At this time, the support frame 140 plays a role of stable support to prevent the hanger from tipping over after the product is hung, thereby preventing the product from being crushed.
