Door plate assembly detection method and door plate assembly detection system

Abstract

The invention discloses a door plate assembly detection method and a door plate assembly detection system, and relates to the technical field of door plate assembly. The invention provides a door plate assembly detection method and a door plate assembly detection system. The door plate assembly detection method comprises the following steps that the assembly working condition of a door plate decoration strip at a station is obtained; the assembly working condition of the door panel decoration strip at the first station is compared with the target assembly working condition of the door panel decoration strip; and when the assembly working condition of the door panel decoration strip at the first station is inconsistent with the target working condition of the door panel decoration strip, a spinning air cylinder at the first station is controlled to be forbidden from being started. Door plate detection and door plate assembly are integrated in a same assembly line, the spinning air cylinder at one station is controlled to be forbidden to be started or started, production assembly work is directly controlled according to the detection result, the problem that traditional assembly line equipment occupies a large space is solved, the production takt is effectively improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle assembly detection, in particular to a door panel assembly detection method and a door panel assembly detection system. Background technique [0002] China's passenger car market is already a huge market, with annual sales exceeding 20 million units. Among the interior parts of the vehicle, the car door panel is the most important, providing functions, comfort and safety requirements for drivers and passengers. [0003] The traditional door panel automatic assembly line is equipped with 2 sets of equipment for door panel assembly and door panel inspection respectively. The door panel assembly includes four stations, one station is the placing station and the sound-absorbing cotton work. After the door panel decorative strip is assembled, the cliff cylinder of the start button presses the door panel, and the lifting cylinder lifts the door panel tire mold to the upper layer. The guide rails of th...

AI Technical Summary

Problems solved by technology

The door panel assembly includes four stations, one station is the placing station and the sound-absorbing cotton work. After the door panel decorative strip is assembled, the cliff cylinder of the start button presses the door panel, and the lifting cylinder lifts the door panel tire mold to the upper layer. The guide rails of the second station and the third station are aligned, and the servo motor will drive the ball screw to move the membrane raised by the lifting cylinder to the second station. After the high-frequency reading and writing recognition door panel at the second station, two The four-axis robot starts to work, and locks the screws on the door panel by means of adsorption. After the assembly of the screws is completed at the second station, the door membrane is moved to the third station, and the third station prepares the door panel according to the identification information of the second station The plastic buckle and metal buckle corresponding to the information, the Yaskawa robot (MH24) installs the plastic buckle and metal buckle on the front of the door panel, and transfers the door panel with the plastic buckle and metal buckle to the four stations for manual preliminary Inspection, after the inspection is passed, the lifting cylinder is lowered, the spinning cylinder is released, and the pick-up operation is performed. After the assembled assembly is removed, the lower layer is synchronized to move the empty tire membrane to the bottom of the second station, and wait for the tire membrane of the first station. Remove the drop, detect that the first station has descended and there is no tire film, the empty tire film at the second station on the lower layer moves to the lower layer at the first station and waits for people to load another door panel to be assembled, and so on, but the door panel assembly and door panel detection Separately, the equipment occupies more space, the production cycle is not high, and the labor cost is high
