Embodiment Construction

[0010] A processing method for terminal welding of a three-phase asynchronous motor, characterized by the following process:

[0011] a), Preparation tools and materials: heat gun, soldering station, solder wire, terminal block, cloth;

[0012] b) Protect the lead wires with cloth to ensure that the protection is in place and there is no quality risk, and the length of the lead wire copper wire is controlled between 8mm-11mm;

[0013] c) Apply solder paste to the end of the lead wire, put on the terminal, and wrap the lead wire to be soldered with a slightly damp cloth to prevent burns and damage to it;

[0014] d) Locally heat the copper wire of the terminal and the lead wire. When the copper wire in the terminal is red, add solder wire, let the heat transfer to the solder wire to heat and melt it, and fill the weld seam. The appearance is required to be full, flat, without omission, and without welding bumps.

[0015] It should be noted that the above embodiments are only ...

Abstract

The invention provides a processing method for three-phase asynchronous motor terminal welding. The method comprises: step (a), tools and materials are prepared; to be specific, a heat gun, a welding stand, a tin wire, a wiring terminal and a piece of cloth are prepared; step (b), a lead wire is protected by the cloth to ensure correct and proper protection and avoid the potential quality hazard, wherein the copper wire length allowance of the lead wire is controlled to be 8mm to 11mm; step (c), the end portion of the lead wire is coated with a soldering paste, the wiring terminal sleeves the processed end portion, and the to-be-welded lead wire is coated by a piece of slightly wet cloth, so that any burning or damage of the lead wire can be prevented; and step (d), the wiring terminal and the lead wire copper wire are heated locally; when the copper wire in the wiring terminal becomes red, the tin wire is added and thus heat is transferred to the tin wire to enable the tin wire to be heated and melted, so that a weld joint is filled. And the appearance is required to be plumb and flat without any missing and weld beading. With the method provided by the invention, raw materials can be saved; the efficiency can be improved; the overall appearance is beautiful and consistent; and the quality problem is solved during the application process of the method.

Description

technical field [0001] The invention belongs to the field of fixing stator coils, and relates to a processing method for electric motor terminal welding. Background technique [0002] The terminal connection of the existing three-phase asynchronous motor is a crucial step. With the development of society, people also have higher requirements for the appearance of the motor. In the past, there are often deficiencies in the manufacturing and subsequent processing methods of terminal connections, which lead to the problems of poor appearance and short service life of terminal connections. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a treatment method for soldering terminals with good appearance and long service life. [0004] The processing method of the welding terminal provided by the present invention is characterized in that the following process: [0005] a), Prepa...
