Being denoted as among the figure wherein: 1-control centre; The 2-brazier; The 3-temperature control equipment; The 4-warning device; The 5-trough; The 6-checkout gear; The 7-transmission device.
The specific embodiment
Be elaborated below in conjunction with the technical scheme of accompanying drawing to utility model:
As shown in Figure 1, the utility model intelligence reflow soldering system comprises control centre, temperature control equipment, warning device, checkout gear, transmission device, brazier; Described control centre is connected with temperature control equipment, warning device, checkout gear, transmission device respectively, and connecting line places in the trough; Temperature control equipment, checkout gear place in the brazier, and the brazier entrance and exit is exposed at the transmission device two ends, and warning device places outside the brazier; Described detection module is arranged on the port of export of brazier; Control centre's control actuator movement, the pcb board that transmission device drives paster enters temperature control equipment by the brazier entrance, described temperature control equipment welds the pcb board of paster, then, the pcb board that the detection module butt welding connects detects, after detection module detected, pcb board left the brazier outlet, and checkout gear is sent to control centre with testing result simultaneously.
Described control centre comprises PC control interface, temperature control modules, transmission control module, detects control module; Wherein host computer interface set temperature, speed, detected parameters, detect the parameter operation that control module is set according to host computer at temperature control modules, transmission control module.
Described temperature control equipment arranges three warm areas, is respectively heating zone, weld zone, cooling zone; Each warm area set temperature sensor; When PCB entered heating zone, solvent, gas evaporation in the soldering paste fell, the wetting pad of scaling powder, components and parts termination and the pin in the soldering paste simultaneously, and soldering paste is softening, slump, covered pad, and pad, component's feet are isolated with oxygen; Preset the heating-up time, make PCB and components and parts obtain sufficient preheating, heat up too fast and damage PCB and components and parts in case PCB enters suddenly the weld zone; When PCB entered the weld zone, temperature rose rapidly and makes soldering paste reach molten state, and liquid scolding tin is to pad, the components and parts termination of PCB and pin is wetting, diffusion, cross flow or recirculate mixing form solder joints; PCB enters the cooling zone, and solder joint is solidified, and finishes whole Reflow Soldering.Temperature sensor detects the temperature of each warm area, and temperature separately is sent to control centre, and control centre controls respectively the work of temperature control equipment in three warm areas automatically according to each warm area sensor signal of receiving.
Described transmission device comprises conveyer belt, velocity sensor, drive motors; Wherein velocity sensor detects the velocity information of conveyer belt, and this velocity information is sent to control centre, and control centre controls drive motors work according to predefined Time Calculation speed.
The rosin joint detecting sensor is set in the described checkout gear, connects tin detecting sensor, Pad off detecting sensor; Sensor in the monitoring device detects the PCB after welding, and the signal that detects is sent to control centre, control centre is sent to the host computer interface display according to the signal of receiving with testing result, so that the user can accurately and timely track welded condition, screen targetedly maintenance.
Described warning device comprises buzzer, LED lamp, and when each module of native system broke down, control centre sent alarm signal according to fault type, so that buzzer sends predefined sound, the LED lamp sends predefined fault-signal.
