Description
Technical field
This utility model relates to silicon wafer cutting device, particularly relates to a kind of with novel high sensitive disconnected
The silicon ingot cutting machine of alarm device.
Background technology
In photovoltaic industry, it is common to use multi-line cutting machine cutting silicon ingot becomes silicon chip, and steel wire is from putting
Line wheel is released, coiling multi-turn in the fluting of two home rolls, thus formation one layer is closely knit on home roll
Uniform gauze, is collected by take-up pulley.Line footpath is thin, and pitch of the laps is many, general line footpath about 0.1mm,
About coiling 2000 circle.When steel wire runs, general reciprocating manner runs, gauze perforated line feelings
Condition inevitably occurs.Once breaking, broken end can be at home roll wound upon themselves, if can not
Detection in time, gauze disappearance can get more and more.Break alarm is malfunctioning is to affect multi-wire saw finished product
The big factors of rate.
Typically, break alarm bar is contained in participation silicon ingot both sides, and upper and lower two positions of gauze are installed altogether
Four alert rod, the stainless steel of general a diameter of about the 5mm of alert rod.Actinobacillus wheel, receipts
Line wheel, 4 alert rod all insulate with equipment body, and they each draw wire and are connected on broken string report
Alert controller input, once detection steel wire turns on contacting alert rod, decides that ground connection, is
System is reported to the police and shuts down；
The impact that time slit, silicon ingot is pressed down, the gauze participating in cut portion can move down, this
The situation of kind is called line bow.Every cutter cutting process, line bow strengthens from zero, finally cuts through phase line bow
Reduce.Therefore alert rod must reserve certain space, and general two alert rod spacing are at 2cm
Above, distance more than guide wheel 3cm.
When cutting area occurs broken string, by tension force effect, general steel wire is along direction of pull level bullet
Go out, be unfavorable for contacting with alert rod；When occurring steel wire to be wound around around one of them home roll, because
Farther out, the end of a thread throws away the probability of overlap joint alert rod and diminishes alert rod distance home roll.The most currently report
Alert bar mode failure probability is bigger.
Utility model content
Utility model purpose, this utility model is for the method inspection of above-mentioned existing detection broken string
Surveying the problem that effect is poor, and provide a kind of novel high sensitive wire break alarm device, it has
Detection results is good, and the function-stable life-span is long, it is easy to accomplish, the spy of absolutely contact after broken string
Point.
Problem to be solved in the utility model is realized by techniques below scheme: provide one
Kind novel high sensitive wire break alarm device, it includes frame, frame internal frame be provided with two parallel
The home roll arranged, is surrounded with the Metal Cutting line for cutting silicon ingot on two home rolls, described
The monitoring surface that half arcwall face is home roll that contacts with line of cut of home roll, the monitoring of each home roll
One or more wire break alarm device it is designed with outside face；Described wire break alarm device includes gold
Belonging to the line of induction, detector and power supply, the described metal line of induction is parallel with home roll, the line of induction
Bearing of trend and line of cut are the most perpendicular through the normal of the direction of travel of monitoring surface,
The radius being smaller than home roll between the metal line of induction and the monitoring surface of home roll.
Further, the other end is fixed by the first leading part in one end of the described metal line of induction
Being connected to be transversely lapped in frame with frame, the metal line of induction and frame insulate, the first leading part by
First insulation board, first bracer, tension block composition, the first insulation board is connected with frame, the
One bracer is fixed on insulation board, and tension block is arranged on above a bracer, and tension block has
Opening, the metal line of induction is around this opening and is bolted on first bracer.
Further, also include controlling detector unit, burn out detection relay, described metal
The line of induction is connected to control the induced signal input of detector unit, burn out detection relay and gold
Belong to the line of induction to be in parallel, the disconnection signal outfan of burn out detection relay and control detector unit
Disconnection signal receiving terminal be connected.
Further, described tension block has sliding opening, between tension block and a bracer
By being connected through the bolt of described sliding opening.
Further, the line footpath of the metal line of induction is 0.1mm.
Further, the described metal line of induction is positioned at the side-lower of home roll, metal line of induction institute
The midpoint of horizontal plane and the metal line of induction and the angle of the line at home roll midpoint more than or etc.
In 45 ° less than 90 °
Further, described line of cut is metal steel wire.
Further, the spacing between the metal line of induction and the monitoring surface of home roll is 2mm～5mm.
This utility model has the advantages that for existing
Alert rod is substituted, it is achieved that following two effect: detection is pre-by setting the metal line of induction
Alert Functional Sensitivity and accuracy are greatly promoted, because the sensitivity level of the line of induction just determines pre-
Alert effect, and cut-off type report when this utility model creation is not general travel switch
Alert, but have employed overlap joint contact and reporting to the police, cut off two kinds of warning function collection of break alarm two is one
Obtain compared to alert rod technology and cut-off type travel switch technology warning effect of the present utility model
To significant increase.
Use the line of induction need not dodge a determining deviation because of line bow impact again, combination accessory performance
Get a promotion.
The line of induction is positioned at outside monitoring surface, wireless bow impact in this region, and greatly shortens
The line of induction and the spacing of monitoring surface, shorten to 2mm～5mm, any disconnection manner in this spacing,
No matter overlap or pump off and will necessarily catch by sensed line.
Use the angle initialization less than 90 ° more than or equal to 45 °, it is ensured that line of cut during broken string
Must there is not same level equal to or more than the spacing of the arc length line of induction and monitoring surface
During broken string fishing line, the end of a thread crosses the situation of the line of induction.
