Ultrasonic cleaning method and cleaning device for flat enameled wire

Abstract

The invention discloses an ultrasonic cleaning method for a flat enameled wire. The ultrasonic cleaning method for the flat enameled wire comprises the following steps: a. first-time cleaning is carried out on the flat enameled wire by an ultrasonic wave, an ultrasonic frequency is 20-25kHz, a cleaning time is 10-20s, a solution for cleaning comprises the following components in parts by weight: 1000 parts of water, 5-10 parts of plastic particles with diameters of 0.1-0.2mm, 3-5 parts of dispersing agent and 1-2 parts of chelating agent, and a product A is obtained; b. an air gun blows away water drops on the surface of the product A, and a product B is obtained; c. second-time cleaning is carried out on the product B by the ultrasonic wave, an ultrasonic frequency is 35-40kHz, a cleaningtime is 5-8s, a solution for cleaning comprises 1000 parts of deionized water and 20-50 parts of anhydrous alcohol, and a product C is obtained; d. the product C is dried, and a product D is obtained; e. the product D is heated, the surface layer of an enameled coating on the surface of the product D is melted, and a product E is obtained; and f. the product E is cooled, and cleaning for the flatenameled wire is completed. The ultrasonic cleaning method for the flat enameled wire has the advantages of being low in cost, and incapable of reducing the electrical property of the flat enameled wire.

Description

technical field [0001] The invention belongs to the field of cleaning enamelled flat wires used in automobile starters, and in particular relates to an ultrasonic cleaning method and cleaning device for enamelled flat wires used in automobile starters. Background technique [0002] The enamelled flat wire used for winding automobile starters has relatively high cleanliness requirements, so it must be cleaned. The existing enamelled flat wire cleaning method is to use the spray device, cleaning cloth and air-drying device of the enamelled flat wire production line to clean. The copper flat wire shuttles and moves on the production line. After being painted and dried, the enameled Flat wire, and then continue to move for cleaning. The specific cleaning method is to spray and clean the spray device first, then scrub it with a cleaning cloth, and finally dry it with hot air in the air-drying device, and finally get a clean enamelled flat wire. [0003] First of all, since the e...

Problems solved by technology

[0003] First of all, because the enameled flat wire has been in contact with the same position of the cleaning cloth for a long time, the contact part between the cleaning cloth and the enameled flat wire is easy to accumulate dirt, and the workers need to change the position of the cleaning cloth frequently so that the cleaning cloth and the enameled flat wire Changes in the contact part of the cloth, and the position of the scrubbing cloth needs to be replaced after several changes

Regardless of the position change or replacement of the cleaning cloth, manual operation is required, and the factory must be equipped with a special person to be responsible, resulting in a high cost of cleaning the enameled flat wire

[0004] Secondly, dirt is easy to accumulate on the contact part between the scrubbing cloth and the enamelled flat wire. When the dirt contains hard particles (such as paint particles and gravel particles), since the particles and the scrubbing cloth are fixed and will not move, the paint The enamelled flat wire continues to shuttle and move, leaving long scratches on the surface of the enamelled flat wire, and the paint layer is damaged, resulting in a decrease in the electrical performance of the enamelled flat wire

[0005] Therefore, the existing enamelled flat wire cleaning method has the defects of high cost and reduced electrical performance of the enamelled flat wire
