Problems solved by technology

[0005] The weighing method can only know the overall weight of the glue road, but the amount of glue per unit length cannot be obtained, and the error is large; the method of measuring the glue width with a 2D camera and measuring the specified glue dispensing height with a laser has fewer sampling points, so There is an error between the calculated glue amount and the actual glue amount

Abstract

The invention is applicable to the technical field of dispensing, and provides a method for setting the dispensing glue amount. The method for setting the dispensing glue amount comprises the following steps of: presetting glue amount of a glue path per unit length and an error range of the glue amount; using a glue dispenser for carrying out dispensing operation; scanning the contour of the glue path through a three-dimensional (3D) laser sensor to obtain contour data; constructing point cloud data based on the contour data; according to the point cloud data, calculating the average glue amount of the glue path per unit length; judging whether the average glue amount is within the error range or not; and when the average glue amount is not within the error range, adjusting parameters of a screw valve of the glue dispenser, and then repeating the steps S102 to S106 until the average glue amount is within the error range. Compared with the prior art according to the method for setting the dispensing glue amount provided by the invention, the average glue amount can be conveniently calculated according to the point cloud data, and the error is small; and the 3D laser sensor is adopted to scan the contour of the glue path, sampling points are abundant, and the calculated average glue amount and the actual glue amount almost have no error. The invention further provides a device for setting the dispensing glue amount and dispensing equipment.

Description

technical field [0001] The invention belongs to the technical field of dispensing, and in particular relates to a method and device for setting the amount of dispensing glue, and dispensing equipment. Background technique [0002] The glue dispenser is mainly used for bonding, pouring, coating, sealing, filling, dripping, linear / arc / circular glue coating of glue, oil and other liquids in the product process, and is used in the manufacture of electronic components, circuit boards Assembly, electrical product production, integrated circuit packaging, precision machinery, biomedicine, light industry, packaging, food and other industries. The appearance of glue dispensing machine has replaced manual glue dispensing in traditional industry, and the quality and efficiency of glue dispensing have been greatly improved. [0003] Before the dispensing machine works, it is necessary to set the dispensing amount of the dispensing machine, that is, it is necessary to adjust the screw v...
