Description

Multi-harness automatic double-head stripping and tinning machine

technical field

The utility model relates to a wiring harness processing equipment, in particular to a multi-wiring harness automatic double-head stripping and tinning integrated machine.

Background technique

Electronic wiring harnesses are often used to connect circuit components to form fully functional circuits. In order to meet the needs of automatic processing of electronic products, the ends of the wires are often processed appropriately, such as tinning the ends of the wires or stripping the wires, so that they can be quickly combined with the connectors during operation. Some of the ends of the electronic wire harness are All have stripped bare wires, and the bare wires must be dipped in solder to achieve better rigidity and no branching wires. The process of dipping solder includes two parts: dipping flux and dipping solder. In the past, when applying flux to the stripped bare wires of the electronic wiring harness, two sponges with flux absorbed were used to sandwich and wipe the stripped bare wires of the electronic wiring harness left and right to make it adhere to the flux. However, this approach has the following disadvantages: 1. The length of contamination by the flux cannot be accurately controlled; 2. The sponge easily reacts with the flux to fragment the sponge, and the fragmented sponge adheres to the electronic wiring harness with the flux. For the bare wire part, the sponge must be replaced frequently, which will invisibly increase the working hours and cost. In addition, when dipping solder in the past, molten solder liquid was put into the tin cup, and a pump was installed in the center of the tin cup to generate gas and rush out of the solder liquid surface, causing it to appear a boiling gushing phenomenon, and discharge on the solder liquid surface. Remove tin slag and scale, and let the wiring harness be stained with clean solder liquid. The disadvantage of this method is that due to the surge phenomenon on the solder surface, the length of solder contamination cannot be controlled.

Recently, a batch of automatic soldering equipment has emerged at home and abroad, improving the traditional process. However, some of these devices have low efficiency, and some have complex mechanical structures, which are costly and difficult to operate and maintain.
