Description
Technical field
The present invention relates to a kind of bare conductor detection device, it is used to detect the bare conductor that is exposed by the end of peeling off electric wire insulation layer.More particularly, the present invention relates to detection technique, it detects the bare conductor of electric wire by adopting the mode of laser beam irradiation bare conductor at the wire harness that disappears.
Background technology
The mode that the electric wire peeler-device of crispaturaing is extensively applied to by removing the electric wire insulation layer end forms bare conductor, and is used for a terminal is connected to bare conductor.As mentioning in JP-A 6-225423 and Japan Patent No.2651305, in some cases, the bare wire checkout gear is used in combination with the electric wire peeler/device of crispaturaing.Whether the bare wire checkout gear detects by removing the bare conductor that comes out in the electric wire insulation layer end, suitably removed with the end of understanding insulating barrier.
The structure of the described bare wire checkout gear of mentioning at JP-A 6-225423 that is used to detect the bare conductor that exposes by the insulating barrier of removing wire end will come general description with reference to Figure 16.Whether the bare wire checkout gear detects electric wire 1 by the mode that adopts laser beam irradiation bare conductor 2, remove the end of electric wire 1 insulating barrier with understanding and suitably finished with the insulation displacement work that exposes bare conductor 2.When the conductor 2 of electric wire 1 crossed laser beam and moves by the direction of arrow shown in Figure 16, the luminous flux that laser beam passes the slit 6 on the optical receiving surface that is formed on photo-detector 4 descended.The photo-detector voltage with the corresponding detection signal of the luminous flux laser beam that passes slit 6 that provide situation over time is provided Figure 17.Zone 1 is that bare conductor 2 begins to cross the period before the laser beam.Zone 2 is that lead 2 has begun period of being right after after crossing laser beam.Zone 3 is periods that lead 2 is moving through laser beam.When detecting voltage VD and continue to remain in the zone between a higher reference voltage VH and the low reference voltage VL within the predetermined time, bare wire checkout gear shown in Figure 16 determines that insulation displacement work is satisfactorily finished.
Be used to from end that electric wire 1 is removed insulating barrier when exposing conductor 2 when having the opposed peeler of peeling off blade, a kind of state of Figure 18 (a) in the various states shown in 18 (e) can be stripped from in the insulating barrier end of electric wire 1.Figure 18 (a) shows a kind of gratifying bare conductor 2 that exposes by the insulating barrier end of suitably peeling off electric wire 1.The electric wire that Figure 18 (b) illustrates has the insulating barrier end 1a that does not remove.In the electric wire that Figure 18 (c) illustrates, the end of conductor 2 is cut.Show in the bare conductor 2 of electric wire at Figure 18 (d), the bottom wire harness 2b of lead 2 disappears, has only the top wire harness 2a of bare conductor to keep not cut.Therefore, the bare wire checkout gear that is used to detect the electric wire of insulation displacement work after finishing also needs to have a kind of function and detects the wire harness that disappears in the bare conductor 2 except the function whether the end 1a with definite insulating barrier has been removed.
Usually, the detected conductor that electric wire had comprises that 7 to 19 wire harness spirality are around centred beam.The conductor 2 of the electric wire 1 shown in is by way of example formed by 6 wire harness arranging around centred beam with 60 degree angular spacings among Figure 19 (a).Bare wire checkout gear shown in Figure 16 adopts single laser beam irradiation lead of advancing along optical axis.The width of supposing a part of laser beam of being hidden by conductor 2 is to hide width.Even bottom wire harness 2b, 2b ' as shown in Figure 19 (b) even and 2d has disappeared or top wire harness 2a, 2a ' and 2c as shown in Figure 19 (c) have disappeared, this covering width can not change yet.Suppose that wire harness arranges with the angle position shown in Figure 20 (a).Even as the bottom wire harness 2b ' as shown in Figure 20 (b) even and 2d has disappeared or top wire harness 2a and 2c shown in Figure 20 (c) have disappeared, this covering width can not change yet.Like this, bare wire checkout gear shown in Figure 16 as can be known can determine whether the end 1a of insulating barrier is removed, but can not determine whether have any wire harness to disappear.
Bare wire checkout gear shown in Figure 16 judges based on the relation that detects between voltage VD and reference voltage VH and the VL whether the end 1a of insulating barrier is removed, so this higher reference voltage VH need be set up in advance with being somebody's turn to do than low reference voltage VL.Since hide the angle position that width depends on wire harness, need being detected to determine a standard so to many electric wires by the satisfied conductor that separates.
Covered by dust if be included in the light emitting devices 3 of bare wire checkout gear shown in Figure 16 and the lens and the filter of optical pickup apparatus 4, will weaken by the luminous intensity of light emitting devices 3 emissions and the luminous intensity that receives by optical pickup apparatus 4 so.Thereby this detects voltage VD and descends.Bare wire checkout gear shown in Figure 16 adopts single laser beam of propagating along optical axis.Therefore, this bare wire checkout gear is difficult to determine to detect the reduction of voltage VD because to hide change width still be because the intensity of laser beam reduction causes, and is that the inspection and maintenance work of light emitting devices 3 and optical pickup apparatus 4 makes troubles.

The structure of the bare conductor detection device 100 among first embodiment and operation will be described referring to figs. 1 to 13.This bare conductor detection device 100 has main unit 10, and this main unit 10 comprises base portion 11a, upper arm 11b and underarm 11c.This main unit 10 has from second horizontal direction and looks the shape of similar substantially letter U.Electric wire 1 with bare conductor 2 moves on second horizontal direction shown in the arrow in by Fig. 1 (a).
The base portion 11a of this main unit 10 comprises laser beam emitter 13 shown in Figure 2 and laser beam beam splitting arrangement 14.Laser beam beam splitting arrangement 14 will be divided into three laser beams equably by laser beam emitter 13 emitted laser bundles.Three laser beam grenade instrumentation 15a, 15b and 15c are arranged among the upper arm 11b.Each laser beam grenade instrumentation 15a, 15b and 15c comprise lens and filter.These three laser beam grenade instrumentation 15a, 15b and the 15c laser beam that projection has equivalent intensity on bare conductor 2 respectively.
As shown in Fig. 1 and Fig. 2, laser beam by laser beam grenade instrumentation 15a, 15b and 15c projection is propagated forward along primary optic axis 16, second optical axis 17 and the 3rd optical axis 18, and drops on respectively on three laser beam receiving system 19a, the 19b and 19c (such as photodiode) that is arranged among the underarm 11c.
Each laser beam has width (that is, the size relevant with second horizontal direction) and thickness (that is, the size relevant with first horizontal direction), and its width is fully greater than the diameter of bare conductor 2.For example, the width of each laser beam and thickness are respectively about 5mm and about 0.3mm.Like this, these laser beams have the shape that is similar to strip.
As shown in Figure 1, primary optic axis 16, second optical axis 17 and the 3rd optical axis 18 are included in the perpendicular that is parallel to second horizontal direction.Primary optic axis 16 vertically extends.Laser beam grenade instrumentation 15a, 15b and 15c from be arranged on upper arm 11b begin, and second optical axis 17 is tilted to preceding extension, and the 3rd optical axis 18 tilts to extend back.From first horizontal direction, second optical axis 17 and the 3rd optical axis 18 be with respect to primary optic axis 16 symmetries, and intersect with miter angle and primary optic axis 16.
Three laser beam receiving system 19a, 19b and 19c provide respectively and the corresponding analog detection voltage signal of the luminous flux of incident laser beam thereon.The analog detection signal that laser beam receiving system 19a, 19b and 19c provide converts the corresponding digital signal of expression luminous flux level (being the luminous flux size) respectively to by A/D converter.The represented luminous flux level of the analog signal that A/D converter provided changes with pattern shown in Figure 3.
In Fig. 3, zone 1 is that bare conductor 2 begins to cross the period before the laser beam, zone 2 is that conductor 2 has begun period of being right after cross laser beam after, and zone 3 is that conductor 2 moves the period of crossing laser beam, and regional 4 is periods that bare conductor 2 is shifting out laser beam.
The base portion 11a of this bare conductor detection device 100 has a built-in controller 20 shown in figure 2.Be sent to three means for correcting 21a, 21b and the 21c that is included in the controller 20 by the digital signal that A/D converter provided.These means for correctings 21a, 21b and 21c proofread and correct the luminous flux level of being represented by analog signal respectively.More specifically, the voltage of the analog detection signal that is provided by three laser beam receiving systems 19a, 19b and 19c is represented the luminous flux that drops on the laser beam on laser beam receiving system 19a, 19b and the 19c respectively.The voltage of the output signal that is provided by laser beam receiving system 19a, 19b and 19c by digital signal representation that A/D converter provided, i.e. luminous flux level.Means for correcting 21a, 21b and 21c for example proofread and correct by the relation between A/D converter received digital signal and the corresponding luminous flux level by increasing by a corrected value to digital signal or deducting a corrected value from digital signal.
Proofread and correct control unit 22 this means for correcting of control 21a, 21b and 21c, so that it is when this bare conductor 2 does not block laser beam, consistent with a predetermined luminous flux level by the luminous flux level of the digital signal representative of being proofreaied and correct by means for correcting 21a, 21b and 21c.Like this, be equal to each other in the zone shown in Fig. 31 by the luminous flux level of these three digital signal representatives, bare conductor 2 does not also begin to cross laser beam in zone 1.Luminous flux level after representative is proofreaied and correct also is sent to highlight flux value/minimum luminous flux value detecting unit 23 by the correcting digital signal that three means for correctings 21a, 21b and 21c are provided.As shown in Figure 3, when bare conductor 2 is pushed into and blocks laser beam, by luminous flux level decline suddenly in zone 2 of the digital signal representative of delivering to highlight flux value/minimum luminous flux value detecting unit 23.When descend by the luminous flux level of at least one representative in these three digital signals and this slippage greater than zone 1 in during the c% of luminous flux level, the detection trigger device (not shown) that is included in highlight flux value/minimum luminous flux value detecting unit 23 detects this decline and starts the sampling function.Subsequently, as shown in Figure 3, highlight flux value/minimum luminous flux value detecting unit 23 is sampled with predetermined times in zone 3 in the given time, and also buffering is about the data of luminous flux level for these three digital signals of receiving, and in zone 3, bare conductor 2 blocks the laser beam of largest portion.Check that this buffered data is to determine minimum and maximum luminous flux level.This minimum and maximum luminous flux level standard of being sent to is provided with unit 24 and identifying unit 25.
As shown in Figure 3, this standard is provided with unit 24 based on by detecting good bare conductor 2 determined minimum and maximum luminous flux level, and an admissible luminous flux zone is set.Standard is provided with unit 24 and calculates upper limit luminous flux by the a% that increases highlight flux to highlight flux, and calculates the lower limit luminous flux by the b% that deducts minimum luminous flux from minimum luminous flux.Admissible luminous flux zone between the upper and lower bound luminous flux is a kind of standard that is used to distinguish good bare conductor and defectiveness bare conductor.
Criterion input unit 26 has provided the a% that is used for the calculating limit luminous flux and the value of b% for standard is provided with unit 24.Like this, when the straightening degree of the size of electric wire 1 or type change or electric wire 1 changed, this standard can suitably change.
If the minimum and maximum light flux values that the bare conductor by detecting electric wire 12 is that determine and provided by highlight flux value and minimum luminous flux value detecting unit 23 is in admissible luminous flux scope, identifying unit 25 provides a handshaking signal.If any one or both are outside admissible luminous flux scope in this minimum and maximum light flux values, identifying unit 25 provides a refusal signal.
Will describe with reference to figure 4 to Fig. 7 among first embodiment by bare conductor detection device 100 performed bare conductor trace routines.
Before beginning this bare conductor trace routine, check this bare conductor detection device 100, and by the detection of good bare conductor (being good sample) being determined the admissible luminous flux scope as standard.
In the bare conductor Equipment Inspection 100 of first embodiment, laser beam beam splitting arrangement 14 will be by three laser beams that are divided into of 13 emitted laser bundles of single laser beam emitter equalization, and these three laser beams are assigned to laser beam grenade instrumentation 15a, 15b and 15c.Equate along three laser beams intensity separately that three optical axises 16,17 and 18 are incident upon on the bare conductor 2 by laser beam grenade instrumentation 15a, 15b and 15c, therefore, in the zone shown in Fig. 31, bare conductor 2 does not block any one of these three laser beams, must be equated by the luminous flux level of the digital signal representative of delivering to highlight flux value/minimum luminous flux value detecting unit 23.If the luminous flux level by these digital signal representatives differs from one another, the luminous flux level correction program shown in the execution graph 4 then.Proofread and correct control unit 22 execution in step S1 to S3 controlling the operation of three correction control apparatus 21a, 21b and 21c, so that under bare conductor 2 blocks the state of any one laser beam in these three laser beams, do not equate by the luminous flux level of the digital signal representative of delivering to highlight flux value/minimum luminous flux value detecting unit 23.When the bare conductor trace routine was not carried out, this bare conductor detection device 100 automatically and constantly was examined.Therefore, before the detection of bare conductor 2 began, the operator needn't adjust this bare conductor detection device 100.If because relevant among laser beam grenade instrumentation 15a, 15b and 15c or laser beam receiving system 19a, 19b and the 19c is stained by dust, and making the decline of any one luminous flux level in the luminous flux level of the digital signal representative that provided by laser beam receiving system 19a, 19b and 19c greater than a predetermined value, means for correcting 21a, the 21b and the 21c that receive the digital signal of the luminous flux level that representative descended then proofread and correct this luminous flux level.Can keep the high accuracy that bare conductor detects like this.
Subsequently, the standard setting program shown in the execution graph 5.This standard (that is admissible luminous flux scope) detects by the good bare conductor to electric wire 1 and is set.Insulated electric conductor 1 with good bare conductor 2 (that is good sample) is supplied to this bare conductor detection device 100 at step S11.When bare conductor 2 begins to block laser beam, by luminous flux level decline rapidly in zone 2 of three digital signal representatives delivering to highlight flux value/minimum luminous flux value detecting unit 23, as shown in Figure 3.
In the S12 step, if judge ratio that luminous flux level descends less than predetermined ratio c%, then bare conductor detection device 100 might break down.Therefore, this standard setting program is interrupted at step S13, and checks this bare conductor detection device 100 in step S14.
After the inspection of bare conductor detection device 100 finished, the electric wire 1 with good bare conductor 2 was supplied to this bare conductor detection device 100.If judge ratio that luminous flux level descends greater than predetermined ratio c% in the S12 step, the detection trigger device that is included in so in this highlight flux value/minimum luminous flux value detecting unit 23 detects this decline and start the sampling function in step S15.
Then, to these three digital signal samples pre-determined numbers, and cushion the data of relevant luminous flux level at step S16 in highlight flux value/minimum luminous flux value detecting unit 23 zone 3 at the fixed time.Then, at step S17, highlight flux value/minimum luminous flux value detecting unit 23 is determined highlight flux and minimum luminous flux based on this buffered data, and minimum and maximum light flux values is delivered to standard setting device 24.
In step S18, the operator operates this criterion input unit 26, imports this standard setting device 24 with ratio a% that will be relevant with type with the size of tested wire 1 and value or the straightening degree of b%.
Then, at step S19, as shown in Figure 3, this standard setting device 24 is determined a standard, that is, and and admissible luminous flux scope.This standard (admissible luminous flux scope) is set like this, and this bare conductor detection device 100 is ready to begin a bare conductor trace routine, so that one after the other detect a plurality of bare conductors 2 of many wires 1.
With reference to bare conductor (that is, product) trace routine shown in Figure 6, at step S21, the electric wire 1 that has detected bare conductor 2 is supplied to this bare conductor detection device 100.
As shown in Figure 7, when bare conductor 2 begins to block laser beam, must decline rapidly in zone 2 by the luminous flux level of three digital signal representatives delivering to highlight flux value/minimum luminous flux value detecting unit 23.At step S22, if the decreasing ratio of determining luminous flux level might break down by this bare conductor detection device 100 so less than predetermined ratio c%.Therefore, this bare conductor trace routine is interrupted at step S23, and checks this bare conductor detection device 100 in step S24.
After the inspection of this bare conductor detection device 100 had been finished, the electric wire 1 with bare conductor 2 was supplied to this bare conductor detection device 100.If the detection trigger device that the rate of descent of determining this luminous flux level at step S22 greater than predetermined ratio c%, is included in highlight flux value/minimum luminous flux value detecting unit 23 detects this decline and starts the sampling function at step S25.
Then, to these three digital signal samples pre-determined numbers, and cushion the data of relevant luminous flux level at step S26 in highlight flux value/minimum luminous flux value detecting unit 23 zone 3 at the fixed time.Then, at step S27, highlight flux value/minimum luminous flux value detecting unit 23 is determined highlight flux and minimum luminous flux based on this buffered data, and should minimum and maximum light flux values deliver to identifying unit 25.
Then, at step S28, identifying unit 25 is checked from the minimum and maximum light flux values that the highlight flux value/minimum luminous flux value detecting unit 23 receives.If this minimum and maximum light flux values meets this standard, that is, if this minimum and maximum luminous flux is in the admissible luminous flux scope, so at step S29, this identifying unit 25 provides a handshaking signal.If this minimum and maximum luminous flux does not meet this standard, that is, if this minimum and maximum luminous flux not in admissible luminous flux scope, so at step S30, this identifying unit 25 provides the refusal signal.

Therefore, when the angle between the angle between optical axis 16 and 17 and optical axis 16 and 18 is 30 when spending, the disappearance that indicates any one wire harness of fork among Fig. 8 all can not be detected.
Shown in Fig. 9 (a) and 9 (b), suppose that angle and the angle between optical axis 16 and 18 between optical axis 16 and 17 is 37.5 degree.So, if bare conductor 2 is in the angle position shown in Fig. 9 (a), by measurement, indicates the wire harness 2a of circle or the disappearance of 2b ' and all can be detected so the covering width 2 of the laser beam that is hidden by bare conductor 2 propagated along optical axis 17.Similarly, the measurement by to the covering width 3 of the laser beam that is hidden by bare conductor 2 propagated along optical axis 18 indicates the wire harness 2a ' of circle or the disappearance of 2b and all can be detected.Yet indicating the top wire harness 2c of fork or the disappearance of bottom wire harness 2d can not be detected, because top wire harness 2c and bottom wire harness 2d are overlapping with other wire harness on optical axis 16,17 and 18 directions of extending.

Shown in Figure 10 (a) and 10 (b), suppose that angle and the angle between optical axis 16 and 18 between optical axis 16 and 17 is 45 degree.So, if bare conductor 2 is in the angle position shown in Figure 10 (a), by measurement, indicates the wire harness 2a of circle or the disappearance of 2b ' and all can be detected so the covering width 2 of the laser beam that is hidden by bare conductor 2 propagated along optical axis 17.Similarly, the measurement by to the covering width 3 of the laser beam that is hidden by bare conductor 2 propagated along optical axis 18 indicates the wire harness 2a ' of circle or the disappearance of 2b and all can be detected.Yet indicating the top wire harness 2c of fork or the disappearance of bottom wire harness 2d can not be detected, because top wire harness 2c and bottom wire harness 2d are overlapping with other wire harness on optical axis 16,17 and 18 directions of extending.
