wiring: simultaneously winding the non-paint-removed part 402 and the paint-removed part 401 of the wiring end of the cleaned aluminum enameled wire 4 for a predetermined number of turns to form a wiring structure on the wire core 301 of the outgoing wire 3;
soldering tin: putting a lead-free tin bar and an aluminum soldering flux into a soldering tin furnace 1, and putting a wiring structure into the soldering tin furnace 1 for tinning to form a soldering joint;
and (3) secondary cleaning: because the aluminum soldering flux has larger oxidizing property, the aluminum soldering flux on the welding head is cleaned after tin coating is finished;
and (3) sealing: the heat-sealed double-walled tube 6 is fitted over the weld head and both ends of the heat-sealed double-walled tube 6 are sealed, and the weld head is isolated from the outside air.
Specifically, this application will adopt full-automatic coiling machine to coil the shape with aluminum enameled wire 4, need adjust the tension of wire winding and the speed size when the wire winding, if the tension of wire winding is too big and wire winding speed is great easily draw off aluminum enameled wire 4.
Specifically, the paint remover for the aluminum enameled wire 4 is poured into a paint removing furnace during paint removal, then a heating couple of a temperature controller is inserted into the paint removing furnace, the heating temperature of the temperature controller is set to be one value of 330-390 ℃, then the wiring end of the enameled wire is placed into the paint removing furnace for paint removal, and before paint removal, one side of a coil facing the direction of the paint removing furnace needs to be wrapped with adhesive paper in advance, so that the coil is prevented from being damaged by splashing paint removing liquid, and a series of potential safety hazards such as turn-to-turn defects of the coil or motor burnout are caused. Specifically, bubbles can be continuously emitted from a paint removing furnace in the paint removing process, when no bubbles are emitted, the paint film of the wiring terminal is removed, and after paint removal, the wiring terminal after paint removal is required to be placed into clear water for cleaning in order to prevent oxidation caused by paint removing liquid residues, and water stains on the wiring terminal are wiped clean by using a rag after cleaning.
Preferably, for the wiring process, the part 402 of the enameled wire terminal, which is not subjected to paint removal, is wound on the wire core 301 of the outgoing wire 3 for more than 2 circles during wiring, the part 401 of the enameled wire is wound on the wire core 301 for more than 3 circles, the distance between the wire winding and the wire winding is controlled to be 1-2mm, and 5-8mm is reserved for the residual wire at the tail end.
Specifically, put into soldering tin stove 1 with wiring structure when soldering tin and handle, because of the difficulty of aluminium enameled wire 4 tin feeding, this application adopts leadless tin bar and aluminium borer scaling powder to put into soldering tin stove 1 as the raw materials and carries out the heating melting, note that the temperature of soldering tin stove should not be too high, avoid the too high temperature to directly fuse aluminium enameled wire 4, this application adjusts 340-365 ℃ with the temperature of soldering tin stove 1 to control soldering tin time control is within 2S, both can guarantee like this under the prerequisite of not fusing aluminium enameled wire 4 that the soldering tin head is full, not having the immersion tin bad, can very big improvement soldering tin' S efficiency.
In order to avoid that the wire skin of the outgoing line 3 is scalded and the wire skin of the outgoing line 3 is wrapped up by the soldering tin layer 5 in order to avoid that the wiring structure stretches into the depth in the soldering tin stove 1 too deeply in the soldering tin process, preferably, the application of the soldering tin depth limiting block 2 for tinning is carried out.
Specifically, the solder depth stopper 2 includes: the two hanging lugs 201 hung on the two opposite side edges of the liner 101 of the soldering tin stove 1 and the tin dipping plate 202 arranged between the two hanging lugs 201, specifically, the width of the tin dipping plate 202 is half of the width of the liner 101 of the soldering tin stove 1 and the tin dipping plate 202 is concave downwards to a preset depth (4-5 mm) in the depth direction of the liner 101. Specifically, firstly, wire stripping is carried out on the outgoing line 3 of the motor (the length of wire stripping is 8-10 mm) during tin coating, at this moment, the tin stove 1 heats the liner 101 of the tin stove 1 (the processing temperature of the tin stove 1 is 340-365 ℃), tin after being heated in the liner 101 of the tin stove 1 is immersed onto the tin dipping plate 202 on the tin soldering depth limiting block 2, meanwhile, as the width of the tin dipping plate 202 is half of the width of the liner 1013 of the tin stove 1, when the tin liquor is insufficient, tin strips can be added into the liner 101 of the tin stove 1, so that the tin liquor is immersed into the tin dipping plate 202 from a new position, specifically, during processing, a user can dip the wire stripped wiring structure into the tin dipping plate 202, at this moment, the tin dipping plate 202 is sunken to a depth of 4-5mm, so that the tin liquor loaded on the tin dipping plate 202 is 4-5mm, and the tin liquor can not be damaged to the wire skins of the aluminum enamel wire 4 and 3 during dipping, and the tin alloy wire core wire can be immersed into the tin alloy wire core of the tin dipping plate 1 and the wire dipping plate can be limited by the conventional technology, and the wire dipping structure can be limited by the wire dipping structure at a long-term when compared with the prior art.
Specifically, for secondary cleaning, the welding head is immersed in an alcohol container during cleaning, the soldering head is brushed by a brush until the soldering head is bright and free of soldering flux residues, specifically, industrial alcohol with the concentration of alcohol being more than 95% is required to be used because the aluminum soldering flux is strong in acid-alkali corrosiveness and general liquid cannot be cleaned, and an oxide film is quickly formed when aluminum is in contact with air because the aluminum is a metal with very active chemical property, so that the surface of the aluminum soldering flux is wiped by alcohol to possibly remove the soldering flux and grease, the surface of the oxide film formed by exposing the aluminum material of the aluminum enameled wire 4 is more complete, in addition, after the soldering head of the aluminum enameled wire 4 is cleaned, the aluminum enameled wire 4 is required to be placed in a heating area and a cooling and weathering area of a drying furnace, and the adsorbed alcohol is removed (the temperature of the drying furnace is 75-85 ℃).

Specifically, the heat-sealed double-wall tube 6 can also simultaneously cover the wire sheath of the outgoing wire 3 close to the wire core 301.
Specifically, a layer of hot melt adhesive is arranged in the double-wall pipe, and after the double-wall pipe is heated, the hot melt adhesive is melted, so that the front air outlet and the rear air outlet of the double-wall pipe are blocked, and the two ends of the double-wall pipe are sealed, so that a welding joint can be isolated from the outside air. In the device, after the heat-sealing double-wall pipe 6 is sleeved into a welding head, the aluminum enameled wire 4 is required to be placed on a draw belt of a tunnel furnace, the aluminum enameled wire 4 is conveyed into the tunnel furnace through the conveying of the draw belt and is conveyed out from the other end, the temperature of the tunnel furnace is set to be 115+/-5 ℃, the speed of the conveying belt of the tunnel furnace is set to be less than or equal to 20r/min, when the heat-sealing double-wall pipe 6 moves in the tunnel furnace, the hot melt glue solution can block the front air outlet and the rear air outlet of the double-wall pipe to prevent the welding head of the aluminum enameled wire 4 from being exposed to the air, oxidation is avoided, and further, the liquefied hot melt glue can stick the aluminum enameled wire 4 after hardening, so that the mechanical strength of the enameled wire is increased.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and are in no way limiting of the invention. Accordingly, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
