Robot integration rear light assembly

Robot integration rear light assembly

The robotic measuring system has the task of inserting a rear light into the side frame of a vehicle body in the best-fit position and holding it for screwing by the worker. The best-fit orientation describes the insertion of the rear lamp from the front position to the end position and the orientation at the joints of the given measurement points.

With the help of the robotic measuring, the robot grabs the rear light from a bracket and holds it in front of the 3D scanner. The 3D scanner determines the position of the lamp on the robot hand and the rear lamp pot. The robotic measuring moves the rear light to a pre-position in front of the car body. Based on the position of the rear light pot and the position of the rear light on the robot hand, a local correction step is calculated in order to be able to roughly insert the lamp into the rear light pot. Using laser sensors and a best-fit algorithm, the position of the luminaire is finely adjusted and optimized. The rear light can then be attached

By using force sensors, special tools and 3D scanners

The robotic measuring has various force sensors for gap and offset measurement. The robot removes the rear light from a defined location via its gripper system and positions it on the vehicle. The alignment takes place at the joints between stray glass and adjacent components. As soon as the end position is reached, a signal is sent for manual screwing.

Using this model, the positioning of a robot is to be evaluated as part of a pre-development project. The sensor and robot design must be designed for various derivatives; the rear light bracket and the rear body must be designed as interchangeable inserts. The rear light bracket must be screwed to the robot on a mounting plate. This plate must be designed for transport with a forklift. The learning of new derivatives using the same connection principle must already be implemented in the plant. The rear body includes the left and right sides of the vehicle to keep the option of installation on both sides by a second robot open.

In further project steps, the robot gripper should be able to pick up all rear lights that are installed on the assembly line. For this purpose, after detailed consultation, the AG must provide CAD models of the following derivatives, which are used as the basis for the construction of the gripper system:

The robot must be able to pick up these spreaders with the same gripper. If there are larger deviations, the gripper can have suction cups on different sides and use the correct holder by turning the gripper. The sensors must be selected and positioned on the robot in such a way that the derivatives listed above can be treated. The rear body must be mounted on a plate/bracket and designed to be interchangeable; the connection must be coordinated with the AG. The rear light holder can also be designed to be interchangeable.

Testing of robotic measuring to ensure quality and function

The measurement robots are specified and defined as a measurement reference in order to create a clear basis for decision-making for the final product evaluation and its approval.

Recognized and valued as a benchmark to meet the OEMs' and suppliers' acceptance scenario and to verify test results in accordance with contracted product specifications, with the aim of accepting the manufacturing quality of the product. Our factory standards and validations guarantee accurate product quality ratings, which are confirmed by our clients' auditors.
