Problems solved by technology

However, the first pass rate of the product appearance of the electrophoretic plating process of the existing NdFeB products is only 50%. The main problems are the bonding force of the paint film, smoothness, high dew point, and uneven coating thickness.
[0003] In terms of electrophoresis technology of NdFeB products, the first-time pass rate of product electrophoresis is low, which not only increases the labor intensity of workers, affects the enthusiasm of workers, but also requires repeated rework

Embodiment Construction

[0014] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0015] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0016] Such as image 3 As shown, the specific steps of the electrophoretic plating process of the NdFeB product include:

[0017] First, soak the NdFeB product in the prepreg solution;

[0018] Electrophoresis tank 1 for NdFeB products (such as figure 1 and figure 2 As shown) extend 1.5 meters to the left as a whole, and add a soaking tank 2, which is equipped with a special prepreg for NdFeB products. The main compon...

Abstract

The invention discloses an electrophoretic coating technology of neodymium iron boron products. The electrophoretic coating technology of the neodymium iron boron products comprises the following steps that firstly, the neodymium iron boron products are soaked in a pre-dip solution; and then, the neodymium iron boron products obtained after pre-dipping are subject to electrophoretic coating. According to the electrophoretic coating technology of the neodymium iron boron products, before the products enter an electrophoresis tank, the products are soaked in the prepared pre-dip solution firstly, then, electrophoretic operation is carried out, a paint film bonding force of an electrophoretic coating is high, flatness is good, the number of exposed points is small, the thickness of the coating is uniform, and the electrophoretic first-pass yield is greatly improved.

Description

technical field [0001] The invention relates to the field of NdFeB protection technology, in particular to an electrophoretic plating process for NdFeB products. Background technique [0002] NdFeB products need electrophoretic coating. However, the product appearance of the electrophoretic plating process of the existing NdFeB products has only a 50% first pass rate. The main problems are the bonding force of the paint film, smoothness, many dew points, and uneven thickness of the coating. [0003] In terms of electrophoresis technology for NdFeB products, the first pass rate of product electrophoresis is low, which not only increases the labor intensity of workers, affects the enthusiasm of workers, but also requires repeated rework. [0004] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the informati...
