Embodiment Construction

[0046] Further description below in conjunction with accompanying drawings.

[0047] like figure 1 As shown in the general flow chart, the image collected offline by the gluing visual inspection device on the gluing track is processed to obtain the pixel distance, and the proportional coefficient is calculated according to the parameter information of the standard glue strip.

[0048] The coordinates of each position of the robot are used as input, and the proportional coefficient obtained through image processing and calculation is used as output to establish a glue quality database.

[0049] like figure 2 The offline establishment of glue quality database is shown in the flow chart and may specifically include the following steps:

[0050] Network initialization, according to the input and output sequence of the system, determine the number of network input layer nodes L, the number of hidden layer nodes H, and the number of output layer nodes O.

[0051] To determine th...

Abstract

The invention discloses a gluing quality data construction method based on an improved extreme learning machine. According to the method, a wavelet theory is introduced into an extreme learning machine; a hidden layer excitation function is constructed by utilizing a wavelet function and any piecewise continuous nonlinear function, a telescopic factor and a translation factor of the wavelet function are initialized according to an input data range, and a gluing quality data construction method based on an improved extreme learning machine is provided in combination with an extreme learning machine sequence inertia online learning method. According to the method, the problem that input data does not have a proportionality coefficient corresponding to the input data in online detection of the gluing quality is solved, necessary prediction information is provided for any position of the gluing track, whether the quality information of the adhesive tape is qualified or not is judged, the detection difficulty of workers is reduced, and the production efficiency of automobile enterprises is improved.

Description

technical field [0001] The invention relates to a method for constructing glue quality data based on an improved extreme learning machine, which belongs to the field of automobile glue detection. Background technique [0002] With the increasing maturity of robot technology and the rapid development of the automobile industry, more and more industrial robots are put into automobile production. It is gradually completing the transformation from manual gluing to robot gluing. Automatic gluing has become a trend. The quality of gluing is easily affected by excessive dilution or viscosity caused by changes in heating temperature, as well as being affected by gluing. The inaccurate coordination between the glue output of the gun and the glue application speed of the robot will affect it. Therefore, it is necessary to inspect the glue application. Nowadays, visual online inspection has become a trend. [0003] Chinese invention patent "On-line Visual Detection Device and Method f...
