Embodiment 1

[0014] This embodiment provides a method for intelligently detecting the amount of solder paste in a solder paste printing machine, including: a solder paste detection system, a visual collector, a through-beam photoelectric sensor, and a mobile handheld terminal; the visual collector is provided with a signal receiver, The through-beam photoelectric sensor is provided with a signal transmitter; the visual collector and the through-beam photoelectric sensor are placed in the solder paste printing machine, the solder paste detection system is connected to the visual collector through the USB2.0 interface, and the solder paste The detection system can exchange information with the mobile handheld terminal through the WIFI wireless network.

Embodiment 2

[0016] This embodiment provides a method for intelligently detecting the residual amount of solder paste in a solder paste printing machine based on Embodiment 1, specifically:

[0017] S1: When the scraper in the solder paste printing machine moves to the through-beam photoelectric sensor, its optical path is blocked, and the through-beam photoelectric sensor transmits the signal to the signal receiver in the visual collector through the signal transmitter;

[0018] S2: The visual collector performs image acquisition after receiving the signal, and then sends the acquired image information to the solder paste inspection system;

[0019] S3: The solder paste detection system calculates and processes the image information, and then obtains the remaining amount of solder paste. Once the remaining amount exceeds the maximum and minimum values ​​of the set threshold range, the solder paste detection system will send a corresponding alarm message Send it to the mobile handheld term...

Abstract

A method for intelligently detecting the residual amount of solder paste of a soldering paste printer specifically comprises the following steps that when a scraper in the soldering paste printer moves to an opposite-emitting photoelectric sensor, the light path of the scraper is cut off, the opposite-emitting photoelectric sensor sends signals to a signal receiver of a visual collector through a signal projector; after the visual collector receives the signals, image acquisition is conducted, and then acquired image information is sent into a solder paste detecting system; the solder paste detecting system calculates and processes the image information, and then the residual amount of soldering paste is obtained; once the residual amount exceeds the maximum value and the minimum value of a set threshold value range, the solder paste detecting system sends corresponding warning information to a mobile handheld terminal of relevant personnel through WIFI to remind the relevant personnel to handle the problem in time. According to the method for intelligently detecting the residual amount of the solder paste of the soldering paste printer, accuracy is greatly improved, the manual operation difficulty is lowered, and defects of insufficient solder, desoldering, bridging and the like can be prevented.

Description

technical field [0001] The invention belongs to the technical field of solder paste printing machines in the SMT industry, and specifically relates to a method for intelligently detecting the residual amount of solder paste in a solder paste printing machine. Background technique [0002] The printing process of solder paste came into being along with the SMT industry of surface mount technology. The quality of the printing process of solder paste is directly related to whether the subsequent placement and reflow process can be carried out normally and orderly. In the current printing process , after the operator applies the solder paste on the stencil, most of the inspection process is still a method of visually observing the solder paste margin. With the continuous printing, the solder paste margin on the stencil is constantly changing, and human The method can easily cause problems such as omission or accuracy, and the insufficient amount of solder paste in the printing p...
