As shown in fig. 1, an embodiment of the first aspect of the present application provides a paint removal welding method for a wire bonding terminal, including:
step 100, immersing the wire bonding terminal 1 in a molten tin stream for stripping.
In step 100, the molten tin flow is normally placed in a tin furnace and is in a liquid state, the temperature of the molten tin flow can reach 300-500 ℃, the physical heating mode of the tin material is fully utilized, and the paint film on the wire welding terminal 1 is carbonized at a high temperature, so that paint stripping is completed.
Step 200, the wire bonding terminal 1 is taken out from the molten tin flow and is crimped with the connecting terminal 2 so as to make the wire bonding terminal 1 and the connecting terminal 2 soldered.
In step 200, when the wire bonding terminal 1 is taken out from the molten tin flow, the molten tin attached to the wire bonding terminal 1 is not yet completely solidified, so that the wire bonding terminal 1 and the connecting terminal 2 need to be immediately crimped, oxides on the paint removing surface can be avoided by quick crimping, and the molten tin can directly play a role in soldering connection on the crimping surface without additionally adding a tin melting process.
According to the wire bonding terminal paint removal welding method provided by the embodiment of the first aspect of the application, the molten tin flow is adopted to paint the wire bonding terminal 1, and the paint removal molten tin is utilized to weld the wire bonding terminal 1 and the wiring terminal 2, so that the welding efficiency is improved. Specifically, the wire welding terminal 1 is immersed in a molten tin flow, the molten tin flow has a higher temperature, insulating paint on the wire welding terminal 1 can be fully carbonized at a high temperature, and as the molten tin flow can infiltrate between the wire cores 11, the insulating paint on each wire core 11 can be removed, the paint removing effect is thorough, no chemical corrosion effect is generated on the wire cores 11 in the paint removing process, no burning roasting is performed, the damage degree to the wire cores 11 is reduced to the greatest extent, in addition, the wire welding terminal 1 is immersed in the molten tin flow, the operation is convenient, and the safety is improved. After the paint removal treatment of the wire welding terminal 1 is finished, the wire welding terminal 1 is taken out from the molten tin flow, at the moment, molten tin is attached to the wire welding terminal 1, when the wire welding terminal 1 is in pressure connection with the wiring terminal 2, the molten tin can directly play a role in tin welding connection on the pressure connection surface, and the process of melting the tin is not required to be additionally arranged, so that the welding process steps are saved, and the connection efficiency between the wire welding terminal 1 and the wiring terminal 2 is improved.
In some embodiments of the present application, the step of immersing the wire-bonding terminal 1 in a flow of molten tin for stripping comprises:
stripping the insulating layer of the wire bonding terminal 1;

As shown in fig. 2 to 4, the wire bonding terminal 1 generally includes a plurality of wire cores 11 with smaller diameter, and when the insulating layer is stripped, the wire cores 11 are generally scattered, so that the crimping nose 12 is sleeved on the wire bonding terminal 1, and it can be ensured that the wire cores 11 cannot be loosened and scattered. Further, the crimp nose 12 is made of copper, and normal both sides are right-angled so as to be better adapted to the shape of the wire bonding terminal 1.
The rosin can help to remove oxides and pollutants on the surface of the wire bonding terminal 1, and in addition, good contact is formed between the wire bonding terminal 1 and the wiring terminal 2 during bonding, so that the bonding reliability is improved. Rosin can also reduce the surface tension of the tin material, so that the tin material is easier to wet the wire welding terminal 1 and the wiring terminal 2, which helps to increase the contact area between the wire welding terminal 1 and the wiring terminal 2, and the welding is firmer. The rosin can form a protective film during the soldering process, preventing oxidation of the surface of the wire-bonding terminal 1, which helps to reduce the influence of oxidation on the bonding quality and provides better conductivity.
In some embodiments of the present application, the step of fitting the crimping nose 12 over the wire bonding terminal 1 includes:
the crimping nose 12 is pressed so that the crimping nose 12 is anchored to the wire bonding terminal 1.
The pressing wire nose 12 forms a hoop effect on the wire welding terminal 1, so that a plurality of wire cores 11 at the wire welding terminal 1 can be compacted and pressed, scattering and loosening are avoided, and the paint stripping effect and the soldering effect are ensured.
In some embodiments of the present application, the step of applying rosin to the wire bond terminal 1 comprises:
the thickness of the smeared rosin is 0.1 mm to 1 mm.
The rosin is uniformly coated, and the rosin is properly coated, so that the auxiliary welding effect of the rosin can be exerted, and the influence of excessive coating amount on welding can be avoided.
In some embodiments of the present application, the step of removing the wire bonding terminal 1 from the molten tin stream and crimping the wire bonding terminal 2 to solder the wire bonding terminal 1 to the wire bonding terminal 2 comprises:
Crimping the crimping lug 12 with the terminal 2;
The terminal 2 is heated so that the molten tin at the press-contact portion is sufficiently melted to cover the press-contact surface.
Specifically, in order to fully ensure the reliability of soldering connection, the terminal 2 can be directly heated by acetylene, the temperature of the terminal 2 can be transferred to the position of the wire welding terminal 1, and the soldered tin material can be additionally and additionally added, so that the tin material flows to the soldered position, and the solder is polished to be flat after being cooled and solidified; the soldering position can be properly adjusted by using an electric soldering iron, so that soldering flux is full and smooth, and the situation that liquid resin or insulating paint enters the welding end in the vacuum casting or vacuum paint dipping process of the motor coil to cause unreliable connection between the wire welding terminal 1 and the wiring terminal 2 is prevented.
In some embodiments of the present application, the step of immersing the wire-bonding terminal 1 in a flow of molten tin for stripping comprises:
controlling the temperature of the molten tin flow to be 300-500 ℃;
The wire bonding terminal 1 is immersed in the molten tin stream for a period of time of 10 seconds to 40 seconds.
When the temperature of the molten tin flow is 300-500 ℃, the paint film of the wire welding terminal 1 can be carbonized at high temperature without damaging the wire core 11, and in addition, the wire welding terminal 1 is immersed in the molten tin flow for 10-40 seconds, so that the paint removal is ensured to be thorough and the damage to the wire core 11 caused by long-time high-temperature soaking can be avoided.
In some embodiments of the present application, the length of the paint removal surface of the wire bonding terminal 1 is 10 mm to 20mm. The length of the paint removal surface of the wire welding terminal 1 can directly influence the quality of soldering connection, the too short connecting area is too small, the wire welding terminal is not easy to weld and easy to break, the too long area of the exposed wire welding terminal 1 can be too large, the welding duration of the soldering connection is increased, the consumption of tin materials and rosin is increased, and the risk of soaking, short circuit and electric leakage of the soldering connection part can exist in the follow-up process. Therefore, the length of the paint removal surface of the wire-bonding terminal is set to 10 mm to 20mm based on multiple factors such as the quality of the soldered connection, the ease of operation, and the like.
