Problems solved by technology

like figure 1 As shown, it includes aluminum wire 3, rolling sheet 6, copper wire lead-out wire 5, copper wire 4, and rolling sheet 6 is used to connect the copper wire 4 that is difficult to connect together at the place where the enameled wire and lead-out wire of the motor are connected. And aluminum wire 3; this copper-aluminum connection process is more convenient and quick to use on aluminum wire motors with large wire diameters, but it is prone to short wires, loose connections and scratches on the paint film when used on small wire diameters, resulting in Reduced motor life

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0019] see figure 2 , including hot melt adhesive 1, heat shrinkable sleeve 2, aluminum wire enameled wire 3, copper wire 4, lead wire 5; the aluminum wire joint welding process with hot melt adhesive mainly includes the following steps:

[0020] 1. Weld the used aluminum wire enameled wire 3 and copper wire 4 (this process is basically the same as the existing common process);

[0021] 2. Immerse the joint of the enameled aluminum wire 3 and the copper wire 4 in the hot melt adhesive 1 at 100°C-120°C, and after about 45 seconds to 70 seconds, wrap the enameled aluminum wire 3 and the copper wire 4 with the hot melt adhesive 1 for welding part;

[0022] 3. Then add a layer of heat-resistant 130°C-70°C heat-shrinkable sleeve on the outside of the hot-melt adhesive 1 (the heat-shrinkable sleeve is semi-closed and can be inserted from the top o...

Abstract

The invention relates to a joint process method of an aluminium wire motor. The method comprises the following steps that: firstly, lead-out wires of aluminium wires and copper wires are welded by using a soldering tin and scaling powder process of a common copper wire motor; secondly, the welded joint is immersed to hot melt adhesive at a temperature of between 100 and 120 DEG C for about 45 to 70 seconds in order that the hot melt adhesive and the joint are fully combined together, thereby achieving the insulation between the joint and the outside and strengthening the tight connection between the aluminium wires and copper wires; thirdly, a thermal shrinkage sleeve which can resist a temperature between 130 and 170 DEG C is arranged on the outside for fixing and molding the joint; fourthly, the joint is heated for 80 to 100 seconds to be fixed and molded. The method uses the process of the joint with colloid and the thermal shrinkage sleeve, adopts the mode of first heating melt adhesive and then the thermal shrinkage sleeve, is convenient to operate and uneasy to break the wire and can be applied to the manufacturing of small-scale aluminium wire motors.

Description

technical field [0001] The invention belongs to the field of motors, and relates to a motor joint, especially a manufacturing process of a small-diameter aluminum wire motor joint. Background technique [0002] At present, most of the joint processes used on aluminum wire motors adopt the rolling method, which is applied to the situation of high-power and large-diameter aluminum wires; for small-diameter aluminum wire motors, the processing method of rolling is difficult to operate in the process. Moreover, the joint is easy to break, and there is a shortcoming that the combination is not tight. [0003] Aluminum wire and copper wire are different substances and cannot be mixed in a liquid state. Using the process of soldering in the past, solder cannot hold two substances together. Moreover, due to the relatively low oxidation temperature of aluminum, it is easy to form an oxide layer on the surface, which hinders welding. In the prior art, the principle of crimping is u...
