Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a safety control device for a robotic riveting workstation. Background Technology

[0002] The robotic riveting workstation is mainly used for the automated riveting of aircraft beam assemblies under 2.5 meters in length for commercial vehicles. Existing automated riveting stations cannot automatically detect or identify various abnormal states during the riveting process, such as whether the riveting die is properly installed after automatic die replacement, whether the die position is offset during riveting, or whether the die has fallen off. The die status relies on manual visual inspection, which cannot meet the demands of fast-paced automated riveting. This results in the robot continuing to rivet even when the die has fallen off, or continuing to rivet with the offset die after it has shifted position, leading to uncontrollable product quality problems such as missed rivets and misaligned rivets, as well as equipment malfunctions such as broken rivets during processing. Utility Model Content

[0003] The purpose of this invention is to provide a safety control device for a robotic riveting workstation, addressing the shortcomings of existing technologies.

[0004] This utility model is achieved using the following technical solution:

[0005] A safety control device for a robotic riveting workstation includes a riveting fixture, which is equipped with a laser sensor and a riveting module. The detection end of the laser sensor is correspondingly set with the riveting module. The laser sensor is connected to a computer via a communication cable, and the computer is equipped with an analysis system.

[0006] Optionally, the riveting fixture has a C-shaped structure.

[0007] Optionally, the riveting module is located at the upper end of the riveting fixture, the riveting fixture is provided with an adjustment base, and the adjustment base is provided with the laser sensor.

[0008] Optionally, the adjustment base has an L-shaped structure, with a base adjustment hole at the vertical end and a sensor adjustment hole at the horizontal end. The adjustment base is connected to the riveting fixture through the base adjustment hole, and the laser sensor is connected to the adjustment base through the sensor adjustment hole.

[0009] Optionally, both the base adjustment hole and the sensor adjustment hole are arc-shaped holes.

[0010] Optionally, the laser sensor is a non-contact laser sensor.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] The laser sensor is connected to the computer via a communication cable, enabling it to automatically identify whether the robot riveting workstation is in the riveting module replacement mode or the automatic riveting mode. In the riveting module replacement mode, the non-contact laser sensor is turned off, while in the automatic riveting mode, the non-contact laser sensor is turned on for automatic detection.

[0013] After activating automatic detection, adjust the base by using the arc-shaped base adjustment hole and the sensor adjustment hole. The angle of the base can be adjusted through the arc-shaped base adjustment hole, and the angle of the laser sensor can be adjusted through the sensor adjustment hole. After adjustment, tighten the adjustment and laser sensor. This ensures that the non-contact laser sensor is firmly fixed on the smooth, irregularly shaped, and frequently moving riveting fixture. It enables the non-contact laser sensor to detect the status of riveting modules of different sizes, with a 100% success rate. This solves the problem of riveting modules falling off, the robot continuing to rivet without contact, or the riveting module continuing to rivet with the offset module after its position has shifted, which leads to uncontrollable product quality problems such as missing rivets and crooked rivets, as well as equipment failures such as breakage of the riveting fixture during processing.
