Embodiment Construction

[0014] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0015] For the precision automatic dispensing device, the specific implementation steps of the present invention are described below in conjunction with the technical scheme and accompanying drawings:

[0016] The first step: fix the substrate 15 in the field of view of the camera, and the gauge block 16 is located on it; move the Z guide rail until the needle 13 touches the upper surface of the gauge block 16 on the substrate, and record the distance between the ranging sensor 9 and the gauge block 16 distance h 1 , and measure the distance H between the distance sensor 9 and the substrate 15 at this time with the distance sensor 9 2 .

[0017] Step 2: Compensate the installation error when replacing the spray needle 13, and calibrate the precision automatic dispensing device through the first drop of gl...

Abstract

The invention provides a precise and automated adhesive dispensing device and method and belongs to the field of adhesive dispensing machines.The precise and automated adhesive dispensing device comprises a three-axis drive unit, an adhesive dispensing machine body unit, a visual positioning unit and a control unit.The three-axis drive unit provides power for the whole device, the adhesive dispensing machine body unit is used for achieving adhesive dispensing, the visual positioning unit is used for achieving precise positioning of adhesive droplets, and the control unit is used for achieving control over the precise and automated adhesive dispensing device.The precise and automated adhesive dispensing device and method have the advantages that a three-dimensional operation rod is utilized to control the three-axis drive unit, the position of the part to be subjected to adhesive dispensing is rapidly represented in the vision of a camera, and the automated degree of the adhesive dispensing device is increased; the proposed first adhesive droplet calibration method is used for compensating the mounting error brought when an adhesive dispensing spray needle is replaced for the precise and automated adhesive dispensing device, on the basis of mounting error compensation, precise positioning and adhesive dispensing of the device are achieved through machine vision, and adhesive dispensing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of glue bonding, and relates to a precision automatic glue dispensing device and method. Background technique [0002] Adhesive bonding technology is the most important key technology in the advanced electronics manufacturing industry. Its process is simple and it is widely used in chip packaging and integrated circuit equipment. However, with the improvement of the integration of precision devices, the amount of glue dispensed, the position accuracy of glue dispensed, and the degree of automation of precision glue dispensers are increasingly unable to meet the requirements. At present, a number of research institutions have carried out related research. The patent No. 201310186242.3 discloses a dispensing machine positioning method, which uses a zero-return calibration module and a zero-return calibration signal to calibrate the dispenser. This dispensing device is in When replacing the needle, the zero ca...
