Integrated monitoring system for wave soldering

Abstract

The invention discloses a wave-soldering comprehensive monitoring system. The system comprises at least one wave soldering machine, at least one monitoring extension, a monitoring switchboard and a communication bus, wherein the monitoring extension is correspondingly connected with the wave soldering machine and is connected with the communication bus by a communication line; and the communication bus is connected with the monitoring switchboard by the communication line. By the wave-soldering comprehensive monitoring system, multiple wave soldering machines can be monitored in real time, so that the same wave soldering machine operator can operate the multiple wave soldering machines.

Description

technical field [0001] The invention relates to a wave soldering monitoring system, in particular to a wave soldering comprehensive monitoring system. Background technique [0002] In the electronic assembly industry, wave soldering technology is one of the most important process technologies. The current status of control in the industry is as follows: [0003] 1. Tin furnace heating board: The tin furnace of wave soldering equipment has three heating boards. The existing technology is powered by three solid state relays. However, if any of the heating boards cannot work normally, the equipment management personnel cannot know in time. Affect the normal operation of wave soldering equipment; [0004] 2. Tin furnace temperature: At present, wave soldering equipment has a timing start function, and there is a mature technology for tin furnace temperature detection, but whether the tin furnace temperature has reached the required state before production at a specific time (su...

Problems solved by technology

[0003] 1. Tin furnace heating board: The tin furnace of wave soldering equipment has three heating boards. The existing technology is powered by three solid state relays. However, if any of the heating boards cannot work normally, the equipment management personnel cannot know in time. Affect the normal operation of wave soldering equipment;

[0004] 2. Tin furnace temperature: At present, wave soldering equipment has a timing start function, and there is a mature technology for tin furnace temperature detection, but whether the tin furnace temperature has reached the required state before production at a specific time (such as 7:00 every day) , or the temperature of the tin furnace is abnormally high, and the off-site equipment management personnel cannot understand the information in time and cannot deal with it in time, which will affect normal production;

[0005] 3. Height of the liquid level of the tin furnace: The liquid level of the tin furnace directly affects the quality of wave soldering. If the liquid level of the tin furnace is too high, there will be a safety risk of tin liquid overflowing, and if the liquid level of the tin furnace is too low, it will affect the quality of wave soldering. Soldering quality, the existing automatic tin-adding technology can only detect the position of the tin liquid at a certain height of the tin furnace;

[0006] 4. The proportion of flux: The proportion of flux is an important parameter of wave soldering quality, and the proportion of flux is easily affected by temperature. However, the existing technology has not carried out real-time detection of the proportion of flux, and it is impossible to grasp the flux in real time. proportion;

[0007] 5. Synchronous monitoring of multiple devices: Usually, an operator in an electronics company is responsible for two or more wave soldering machines at the same time, and each wave soldering machine works independently of each other. When one of the wave soldering machines appears When there is an abnormality, and the operator is in another wave soldering machine position, at this time, it will not be possible to carry out emergency treatment on the abnormal wave soldering machine in time, delaying the best time to solve the abnormal wave soldering machine, and then affecting the normal operation of the wave soldering equipment and normal production order
