Problems solved by technology

During the production process of the body controller, the accurate detection of the positive position of the pin on the connector is an important part of the quality inspection of the body controller. The flatness and positive position of the connector terminals vary greatly, which will cause short circuits and open circuits and other serious consequences
The traditional pin position detection method relies on manual detection with measuring equipment, which has low accuracy and low efficiency, and the degree of automation and reliability is not high.

Embodiment Construction

[0025] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] First set the coordinates of 6 detection stations in the PLC (16), set the process parameters of the current batch of body controllers in the host computer (17), and then start the detection.

[0027] When the test starts, the product to be tested (11) is manually placed on the tray (10), and the PLC (16) drives the servo motor (13) through the motor controller (14) to carry the product to be tested (11) to the first one in area A. The connector (PWR2) detects the station, and when it is in place, the PLC (16) sends a signal in place through OPC communication, and the host computer (17) triggers the camera (1) to take pictures, and after obtaining the pictures, the image processing is completed by the following 5 steps:

[0028] (1) Calibrate and calibrate the collected images, select a checkerboard calibration plate with a grid size ...

Abstract

The invention discloses an automatic true position detecting method and specifically relates to a true position detecting method for a pin of a socket connector of a vehicle controller. A detection system includes an image collecting unit, a motion control unit, a servo motor unit, an upper computer processing unit and an auxiliary device. A method of arranging three cameras in three zones including an A zone, a B zone and a C zone for detection is designed according to distribution characteristics of socket connectors. After the system is started, the motion control unit drives a to-be-detected product to a detection station and triggers a photo taking signal. The image collecting unit collects images and sends the images to the upper computer processing unit for processing and the processed data is recorded. An image processing algorithm is used for detecting the true position of the pin of the socket connector and a detection result is displayed and an implementation signal is given out. Later, the motion control unit drives the to-be-detected product to a socket connector station for a next step. By using the method provided by the invention, quick, accurate and automatic detection of true position of the pin of the socket connector of the vehicle controller can be realized.

Description

technical field [0001] The invention relates to a product size detection method, in particular to a machine vision-based automatic detection method for the positive position of a connector pin of a vehicle body controller, belonging to the field of product detection. Background technique [0002] Automotive electronics technology realizes the centralized control and system management of vehicles, and has become one of the basic technologies for the development of modern automobiles. Among them, the body controller improves the comfort and convenience of driving, and its importance is becoming increasingly prominent. During the production process of the body controller, the accurate detection of the positive position of the pin on the connector is an important part of the quality inspection of the body controller. The flatness and positive position of the connector terminals vary greatly, which will cause short circuits and open circuits and other serious consequences. The t...
