Description

A clip soldering apparatus using a hot wind type}

The present invention relates to a soldering apparatus of a clip, which is an electrical contact terminal for supplying power to a heating wire pattern formed on the rear glass of a vehicle, and in particular, to ensure that the clip is accurately positioned at the soldering position of the glass, and the speed of soldering is uniform by the hot air method. The present invention relates to a clip soldering apparatus capable of quickly soldering.

In general, the heating wire pattern formed on the rear glass of the vehicle generates a heat of about 55-70 ° C. by receiving a voltage of 12v to 13.5v and a current of 13A to 16A to remove moisture or frost. The hot wire pattern is made of an ink mixed with a silver material and a special paste, and a line having a thickness of about 0.6 mm is formed in parallel on the glass about 10 to 14 lines.

In addition, the heating wire pattern is provided with a clip that is an electrical supply terminal is operated by receiving power from a generator or battery of the vehicle.

On the other hand, in the process of soldering the clip to the heating wire as described above, the first step in which the worker puts the glass loaded on the pallet on the conveyor, and the two workers solder the clip on both sides of the conveyor The second step and the third step of measuring the current by contacting the current rod to the hot wire and the clip and checking the disconnection of the hot wire, these three processes are usually carried out with a cycle time of 45 seconds (Cycle Time) .

In the conventional clip soldering process that goes through a series of processes as described above, to perform a process such as soldering a clip or checking the disconnection, a pair of two workers are always required, and when soldering a clip, There is a problem that the speed of soldering is non-uniform because it is performed by the operator by hand. In addition, it is not only difficult to accurately position the clip at the soldering position of the glass, but also a lot of differences occur depending on the skill and experience of the operator has a problem that the product is not made uniform to the standard specifications.

Meanwhile, in the conventional indirect heating soldering apparatus, the soldering process is performed while the glass is horizontally placed on the conveyor belt, and the trajectory of the robot holding the heater and the clip is made only by the input coordinates. Therefore, the molding state of the glass is different for each, and if the error range is widened or narrowed by more than ± 5mm because the deviation of the robot's trajectory, the attachment position of the clip and the heat transfer point will vary depending on the relative angle change.

Accordingly, in a state in which the glass is inclined, the process of soldering the clip to the position to which the clip is attached was possible only in the range of ± 5 mm in deformation of both ends of the glass, that is, in the pillar portion. If it is out of the range, there is a problem to solve the soldering problem by manual work. In addition, since the portion to which the clip is attached is inclined, a liquid lead material flows along the inclined surface of the glass during soldering, thereby causing a defect in glass.

Accordingly, the present invention has been made to solve the above problems, and the soldering of the clip by the automatic supply of the clip using a robot and the hot air generator which is a heating medium that indirectly transfers heat to the clip. It is an object of the present invention to maintain a constant speed and shape, and to provide a clip soldering apparatus based on a hot air method capable of producing a uniform product by accurately positioning a clip at a clip soldering position of glass.
