Description
Technical field
The present invention relates to tin silk transfer equipment field, specifically, relate to the device of a kind of automatic detection tin silk obstruction or fracture of wire.
Background technology
Soldering is as a kind of important production technology, be widely used in different products, along with the fast development of electronic product, requirement to soldering technique is also more and more higher, the quality of soldering technique can directly have influence on the quality and performance of final products, and wherein the state of wire feed can have a strong impact on whole production process, this just need to monitor accurately and survey wire feed process in production process.
Existing wire feed control method mainly contains two kinds, artificial wire feed and automatic feeding.
Artificial wire feed is mainly by the manual wire feed of workman, its automaticity extreme difference, and the stability of wire feed process greatly depends on operator's skilled technical ability, and do not possess the prospect of large-scale industrial production, therefore, these class methods have been difficult to existence in large-scale production.
The mechanism of automatic feeding is more, but structure is similar, and now comparatively popular automatic wire feeding mechanism carries out example on the market:
1. by a gear, utilize the own wt of gear and motor, push down tin silk in a narrow groove, and produce frictional force when gear rotates, drive tin silk to move, same, by the speed of governor motor, regulate the speed of tin feeding wire, as shown in Figure 1;
2. on the basis described in 1, increased a motor and gear, engaged by two gears the tin silk producing in the middle of engagement force drive and move, by governor motor speed, control gear rotary speed, thus regulate wire feed rate.
But in actual production, often due to a variety of causes, tin silk can occur to be blocked or fracture of wire phenomenon, if now found not in time, the production process of leaving continues to go on, likely cause a large amount of losses, therefore must find a kind of device or the method that can find in time tin silk obstruction or fracture of wire accident.
Summary of the invention
In view of this, need to overcome at least one in above-mentioned defect of the prior art.The device that the invention provides a kind of automatic detection tin silk obstruction or fracture of wire, comprises pedestal;
The drive unit that utilizes pulse current to drive, the described drive unit that utilizes pulse current to drive is arranged on pedestal;
Driving wheel, described driving wheel is arranged on the output shaft of described drive unit;
Driven pulley, described driven pulley is relative with described driving wheel to be arranged on described pedestal, and tin silk passes through between described driving wheel and described driven pulley;
Encoder wheel, described encoder wheel is arranged on the rear of described driven pulley and described driving wheel, and its mounting means pulls direction to install for complying with tin silk;
Auxiliary wheel, described auxiliary wheel is arranged on the offside of described encoder wheel, and tin silk passes through between described encoder wheel and described driven pulley;
Described driving wheel, described driven pulley, described encoder wheel, described auxiliary wheel are installed in the homonymy of described pedestal, and its mounting means pulls direction to install for complying with tin silk;
Described encoder, described encoder and described encoder wheel are connected;
Described controller, described controller and described encoder, described drive unit are connected respectively, and described controller comprises the poor unit that compares of signal pulse.
According to the present invention in background technology to described in prior art, current wire feeder cannot to block or fracture of wire survey in time and stop, therefore there is production hidden danger; And provided by the invention by employing utilize the motion of tin silk drive described encoder wheel move to block or fracture of wire survey, removed the problem in production process.
When tin silk is clipped between described driving wheel and described driven pulley, by utilizing the described drive unit of pulse signal control to drive described driving wheel motion, described driven pulley is assisted the common tin silk wire feed that drives, in the time that tin silk moves, drive described encoder wheel to move together with described auxiliary wheel, the rotation of described encoder wheel feeds back in described controller after making described encoder produce count pulse; Described controller compares the driving pulse of count pulse and described drive unit, if deviation of signal in permissible range, thinks that the action of wire feed is normal; If when deviation of signal has exceeded permissible range, judge the remarkable action of tin feeding wire, and deviation of signal is while having exceeded permissible range, means wire feed process exception, stops immediately stepper motor and rotates and report to the police.
In addition, also there is following additional technical feature according to the device of automatic detection tin silk obstruction disclosed by the invention or fracture of wire:
Further, described drive unit is motor.
Further, described motor is stepper motor or servomotor.
Further, controller is single-chip microcomputer or CPU or PLC controller.
Further, described driving wheel or described driven pulley or described encoder wheel or described auxiliary wheel have the race for embedding tin silk.
Adopt race to have guide effect better to tin silk, avoid tin silk to occur the deviation of directivity in wire feed process, generally, described race transverse shape is the circular contour matching with tin silk cylindrical.，
Further, described driving wheel or driven pulley or encoder wheel or auxiliary wheel comprise the internal layer of hard material structure and the skin of flexible material structure.
Because the general quality of tin silk is softer, if therefore adopt hard material, very easily will make tin silk profile become irregular, therefore described outer flexible structure material can reduce the variation of tin silk profile.
Further, the skin of described flexible material structure is rubber structure layer.
Further, described signal pulse poor than unit deviation permissible range in 2000 of pulse signals.
Owing to blocking at tin silk or when fracture of wire, described driving wheel cannot drive described encoder wheel to carry out normal rotation, therefore there is difference by the umber of pulse of passing to described encoder in described encoder wheel in the umber of pulse of described drive unit input, when in 2000, judge wire feed process exception, so can avoid in time production loss.
Further, described signal pulse poor than unit deviation permissible range in 1000 of pulse signals.
Preferably, described signal pulse poor than unit deviation permissible range in 600 of pulse signals
