Based on above-mentioned system for the control hot weld time, correspondence of the present invention provides a kind of method that is used for the control hot weld time that adopts this system, sees also Fig. 3, and its step comprises:
S100, access power supply, LED light are lighted and are shown that magnetic answers the hot weld control device in running order, by the hot weld control module are set according to the material of product to be welded the hot weld time, and it is fixing that product to be welded is put into tool.
Behind the connection dc source of the socket in the power management module (5V), the LED light in this power management module is lighted, and it is in running order that then magnetic is answered the hot weld control device.Can regulate the hot weld time this moment by the toggle switch in the hot weld control module, and the length of hot weld time is determined by the material of putting into the product to be welded or to be unloaded on the tool.Behind the fixing product to be welded of pressing plate pressing, the closed magnetic field stress that produces of the permanent magnet on the tool.Heat gun is taken out from support, trigger the induction installation on the support behind the operating grip disengaging support of heat gun, heat gun enters duty.This moment can be at its temperature of control instrument adjusted and the wind-force of heat gun.
S200, startup magnetic field stress detection module detect magnetic field intensity and transfer to magnetic and answer in the contactless control module, magnetic should be contactless control module judge the size of magnetic field intensity: when magnetic field intensity during greater than preset strength, magnetic should contactless control module output drive signal to main control module; When magnetic field intensity during less than preset strength, magnetic should contactless control module continues to judge the size of magnetic field intensity.
Permanent magnet makes stress detection module automatic startup the in magnetic field begin to detect magnetic field intensity and transmission when producing magnetic field stress.Described preset strength is determined by the appearance value of the first capacitor C 1, the second capacitor C 2 and the resistance of the second resistance R 2.Magnetic field intensity represents that greater than preset strength magnetic field intensity reaches foot in driving the circuit that is comprised of the first capacitor C 1, the second capacitor C 2 and the second resistance R 2, and the driving signal of output is to main control module.Be unfavorable for direct-detection temperature and sensor installation based on the prior art means, the present invention adopts the time length of the mode indirect control and supervision welding that detects magnetic field intensity, and not only implementation is simple, and easy to operate cost is low, and the degree of accuracy of detection is also higher.
S300, main control module according to the driving unblanking bond pattern that receives, carry out the hot weld time, judge whether the hot weld time arrive: if the arrival of hot weld time, then output low level is to air pressure gun control module, execution in step S400; Otherwise, keep high level output, continue to judge whether the hot weld time arrives.
When welding personnel welded, main control module was carried out the hot weld time that the hot weld control module pre-sets, and the length that is about to weld interval is controlled to be the length of hot weld time.The time of the actual welding that main control module record is current, with the hot weld time relatively, when weldering time equals the hot weld time, with regard to output low level; The time of having welded does not also arrive the hot weld time, continues to judge whether the hot weld time arrive, and then welding personnel can continue to weld simultaneously.
S400, air pressure gun control module are bright according to going out of the high-low level control warning light of input, and output corresponding control signals welding machine opens and closes.
Arrive when the hot weld time, what the air pressure gun control module received is low level, and the first triode conducting is lighted warning light, reminds the current welding operation of welding personnel to finish; Also the control signal of output low level quits work welding machine simultaneously; When the hot weld time did not arrive, the high level that the air pressure gun control module receives made the cut-off of the first triode, the state that the warning light maintenance did not work originally, and the control signal of this moment does not affect the current duty of welding machine.Welding personnel can be for the better hot weld time of different electronic product settings like this, level and the efficient of hot weld technology have been improved, guaranteed the quality of welding, to the damage of circuit on pcb board components and parts, pad or the pcb board, solved the loss of material that electronic product causes because of the hot weld error when producing maintenance when avoiding welding personnel with personal experience's hot weld.
Be understandable that, concerning the common welding personnel in this area, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection domain of the appended claim of the present invention.
