Control system for scaling powder spraying machine

Abstract

The invention discloses a control system for a scaling powder spraying machine. The control system comprises an industrial personal computer, a main controller, a temperature controller connected with the industrial personal computer, a heater controlled by the temperature controller, a first sensor used for collecting heating temperature signals of the heater, and a second sensor used for detecting the spraying amount of scaling powder sprayed by the spraying machine. The main controller is connected with a welding machine controller. A scaling powder spraying air cylinder and a driving motor of the spraying machine are controlled by the main controller. The scaling powder spraying air cylinder and the driving motor are both connected with the main controller. The scaling powder spraying air cylinder and a spraying device of the spraying machine are in transmission connection. The driving motor is in transmission connection with a moving mechanism which drives the spraying device to move. The control system is simple in structure, convenient to use and operate, good in using effect and capable of effectively solving the problems that existing scaling powder spraying equipment is not accurate enough in temperature control, scaling powder spraying amount is hard to control, scaling powder cleaning is not convenient enough and the like.

Description

technical field

[0001] The invention relates to an automatic control system, in particular to a control system for a flux sprayer. Background technique

[0002] With the development of the market-oriented economy, the market competition of electronic products is becoming more and more fierce. Improving the production efficiency of electronic products can reduce the production cost of enterprises, thereby improving market competitiveness. During the process of processing, the circuit board must be welded by the wave soldering machine. After the circuit board enters the wave soldering machine through the conveyor belt, the flux spraying device is installed in the wave soldering machine, and the flux spray gun device sprays flux on the circuit board. The quality of flux spraying directly affects the quality of circuit boards.

[0003] Although flux spraying devices have been continuously developed in recent years, there are still some problems that cannot be ignored, such as i...
