Description

  The present invention relates to an electric wire processing machine provided with a strip state inspection device for determining whether or not a strip state of an electric wire having a stripped strip is processed, and a photoelectric sensor detection position setting method thereof.

  Conventionally, as an example of an electric wire processing machine, as shown in FIG. 8, the electric wire 1 supplied along a predetermined electric wire supply direction P is measured and cut, and the covering portion at the end of the cut electric wire 1 There is a so-called both-end terminal crimping device 16 for crimping a terminal to one end of the electric wire after stripping.

  That is, such a both-ends terminal crimping device 16 sequentially feeds the electric wires 1 along a predetermined electric wire supply direction P and measures the length of the feeding amount, and also cuts and strips the electric wires 1. The cutter unit 3 to be performed, the front-side clamp device 4 and the rear-side clamp device 5 as gripping clamps arranged on the upstream side and the downstream side in the electric wire supply direction P with respect to the cutter unit 3, and the front-side clamp device 4 and the rear Front-side terminal crimping unit 6 and rear-side terminal crimping unit 7 for crimping the terminals to the ends of the electric wires 1 respectively held by the side clamp device 5 and front-side moving means 9 for moving each of the clamp devices 4 and 5. And a rear side moving means 10 and a wire discharge tray or the like as a wire discharge portion from which the manufactured harness is discharged. There is a structure having on the pedestal 12.

  In addition, photoelectric sensors 14 and 15 for detecting the strip state of the covering portion of the electric wire 1 in a non-contact manner are arranged corresponding to the passage paths of the electric wires 1 clamped by the clamp devices 4 and 5. The strip condition inspection apparatus having the photoelectric sensors 14 and 15 detects the passage time t when the core wire portion of the stripped electric wire 1 passes through the positions of the photoelectric sensors 14 and 15, and is set in advance. It is controlled so as to determine whether the strip state is good or not based on whether or not it is within the allowable value range compared with the passage time t of the determination value.

  Further, an operation unit operated by an operator is provided on one side or the like of the mounting table 12 so that the both-end terminal crimping device 16 is driven and controlled in accordance with an operation on the operation unit. It is a control device as a control unit that drives and controls the terminal crimping device 16.

  And the electric wire 1 sent out predetermined length along the electric wire supply direction P by the length measuring unit 2 is each clamped by the front side clamp apparatus 4 and the rear side clamp apparatus 5, and is cut by the cutter unit 3 in that state The electric wire 1 clamped by the front-side clamp device 4 and the electric wire 1 clamped by the rear-side clamp device 5 and then the electric wire 1 terminal portion clamped by each of the clamp devices 4 and 6 is a cutter. The cover is stripped at the set position by the unit 3.

  When the electric wire 1 clamped in the front side clamping device 4 subsequently passes the position of the photoelectric sensor 14, whether or not the strip state is good is determined. If there is no abnormality, the electric wire 1 is moved to the position of the front side terminal crimping unit 6 and operated. A terminal is crimped to the covering strip portion by the side terminal crimping unit 6. After the terminal crimping process, the electric wire 1 clamped by the front-side clamping device 4 is returned to the initial position facing the cutter unit 3.

  On the other hand, while the terminal 1 is crimped to the electric wire 1 on the front side clamp device 4 side, the electric wire 1 on the rear side clamp device 5 side also passes through the position of the photoelectric sensor 15, and at this time, the quality of the strip state is determined. If there is no abnormality, the rear side terminal crimping unit 7 is moved to the position, the terminal is crimped to the covering strip portion by the rear side terminal crimping unit 7, and then the wire 1 is placed on the wire discharge tray by the unillustrated discharge unit. The rear clamping device 5 is returned to the initial position facing the cutter unit 3.

  Then, as described above, the operation of the length measuring unit 2 causes the electric wire 1 to be sent out by a predetermined length along the electric wire supply direction P, and by repeating the same operation, the electric wire 1 has a predetermined electric wire length with terminals crimped to both ends. Harnesses were sequentially manufactured.

  As a setting method of the determination data in the strip state inspection device, as shown in FIG. 9, after the covering portion of the electric wire 1 is strip-processed by the cutter unit 3 (step S1), as shown in FIG. The core wire portion 1a passes through the position of the photoelectric sensor 14 at a predetermined constant speed. When the core wire portion 1a passes the position of the photoelectric sensor 14, the photoelectric sensor 14 is shielded from light and a detection signal is detected. The time detected by the light shielding is measured as the passage time t (step S2), and the passage time t is collected (step S3). That is, the data is sequentially added to the buffer and stored.

  Next, it is determined whether or not sensing of 20 passage times t has been performed after the core wire portion 1a has passed 10 reciprocations through the position of the photoelectric sensor 14 (step S4), and if 10 reciprocations have not elapsed, Return to step S2.

  In step S4, if 10 reciprocal sensings are performed, the average of the passage time t of the core wire portion 1a is obtained by calculation. That is, the addition time of the passage time t stored in the buffer is divided by the number of times of 20. Then, the obtained passage time t of the core wire portion 1a is acquired and set as a determination value for determining the quality of the strip state (step S5).

  Similarly, the passage time t as a determination value for determining the quality of the strip state is set for the photoelectric sensor 15 on the rear side as well.

  And at the time of electric wire processing, when the core wire part 1a of the electric wire 1 clamped by the clamping devices 4 and 5 moves to the terminal crimping unit 6 and 7 side, it passes through the photoelectric sensors 14 and 15 positions, and the passing time t Control is performed so as to determine whether the strip state is normal, whether the core portion 1a is broken, or the strip is missed, depending on whether or not it is within the allowable value range compared to the set determination value passage time t. Is done.

  In addition, as an inspection device for inspecting the strip state of such an electric wire terminal portion, a non-contact type corresponding to each passage route of the core portion of the electric wire whose strip portion has been stripped and the covering portion which has not been stripped. A structure in which photoelectric sensors are respectively arranged to judge the quality of the strip state (for example, see Patent Document 1), or a structure in which a television camera is arranged and the quality of the strip state is judged based on the captured image data. (For example, refer to Patent Document 2).

Japanese Patent Laid-Open No. 61-154212 JP 61-133871 A

  However, according to the structure in which only the core portion 1a is detected and the quality of the strip state is determined, since the covering portion is not sensed at all, even when the wire 1 having a different wire diameter is set incorrectly, it is overlooked. Therefore, there is a possibility that the terminal crimping process is performed.

  Further, as shown in FIG. 10, although the clamping position A of the electric wire 1, the cutting position B by the cutter unit 3, and the cutting position C for strip processing by the cutter unit 3 are specified, in the electric wire 1 subjected to strip processing, The strip end surface position D, which is the end surface of the covering portion 1b, is a stripping force at the time of stripping due to improper adjustment of the cutter blade in the cutter unit 3, and the covering portion 1b is stretched in the direction of the end of the electric wire 1 and May not match.

  Therefore, sensing is performed such that the optical axis of the photoelectric sensor 14 is separated from the cut position C by a certain distance L (for example, 1 mm) with a certain margin in the axial direction of the electric wire 1, that is, on the core portion 1 a side. It was controlled.

  Therefore, as shown in FIG. 11, when the strip 1 is stripped, the photoelectric sensor 14 cannot effectively detect the covering 1b when the coating 1b greatly expands to the core 1a due to wear or misalignment of the cutter blade. There is a risk of causing a so-called coating biting failure in which the coating portion 1b is also crimped to the core crimping portion for crimping the core portion 1a of the terminal. In particular, due to the recent thinning of the electric wire 1 and the miniaturization of the terminal, a more strict strip state inspection device is being demanded.

  Further, the inspection apparatus disclosed in Patent Document 1 has the same drawbacks, and further requires a pair of photoelectric sensors, resulting in a high cost.

  Furthermore, according to the inspection apparatus of Patent Document 2, since a television camera is used, there is a drawback in that the cost is further increased.

  In view of these problems, an object of the present invention is to provide an electric wire processing machine and a photoelectric sensor detection position setting method capable of effectively determining the quality of a strip state with a single photoelectric sensor.

  The technical means of the electric wire processing machine for solving the above-mentioned problems is an electric wire processing machine provided with a strip state inspection device for judging whether the strip state is good or not according to the photoelectric sensor position passing time of the electric wire whose strip is stripped. A control unit for driving and controlling the electric wire processing machine has an automatic sensor adjustment function, and the automatic sensor adjustment function moves the strip-processed electric wires by a predetermined value in the axial direction of the electric wire from the core wire region. Sensing control that collects photoelectric sensor position passage times of multiple parts that reach the covering region, strip end face position detection control that detects the strip end face position from the increase / decrease change in the photoelectric sensor position passage time collected by the sensing control, From the collected time of the photoelectric sensor position on the end side and the opposite side from the strip end surface position, the core A core wire passage time detection control and a coating portion passage time detection control for detecting a portion passage time and a covering portion passage time, and an end face proximity separated by a predetermined amount from the detected strip end face position toward the core wire portion. A photoelectric sensor detection position setting control for setting the position to the detection position of the photoelectric sensor is provided.

  In addition, the technical means of the photoelectric sensor detection position setting method of the electric wire processing machine for solving the above-mentioned problem is a strip for determining whether the strip state is good or not according to the photoelectric sensor position passage time of the electric wire whose strip is stripped. In the photoelectric sensor detection position setting method of an electric wire processing machine equipped with a state inspection device, the stripped electric wires are moved by a predetermined value in the axial direction of the strip, and a large number of photoelectric elements from the core wire region to the covering region are obtained. Sensing step for collecting sensor position passage time, strip end surface position detection step for detecting strip end surface position from increase / decrease change in photoelectric sensor position passage time collected in the sensing step, and strip end surface position detection step. The collected photoelectric sensor positions on the end side and the opposite side from the strip end face position The core wire portion passage time detection step and the covering portion passage time detection step for detecting the core wire portion passage time and the covering portion passage time from the passage time, and the strip end surface position detected in the strip end surface position detection step from the strip end surface position toward the core portion. And a photoelectric sensor detection position setting step of setting an end face proximity position separated by a predetermined value as a detection position of the photoelectric sensor.

  As described above, according to the wire processing machine of the present invention, the control unit that drives and controls the wire processing machine has the automatic sensor adjustment function, and the automatic sensor adjustment function determines the stripped wire in the axial direction. The strip end face position is detected from the sensing control that collects the photoelectric sensor position passage time of many parts from the core line area to the covering area by moving each value and the increase / decrease in the photoelectric sensor position passage time collected by the sensing control. Strip end surface position detection control, core line portion passage time detection control for detecting the core portion passage time and the covering portion passage time from the collected photoelectric sensor position passage times on the end side and the opposite side from the strip end surface position, and Covering section passage time detection control, and near the end face that is separated from the detected strip end face position by a small predetermined value in the direction of the core wire section. It is configured to have a photoelectric sensor detection position setting control for setting the position to the detection position of the photoelectric sensor, and the stripped electric wire is moved by a predetermined value in the axial direction of the strip, so that the covering portion is moved from the core wire region. Collect the photoelectric sensor position passage time of many parts to reach the area, detect the strip end face position from the increase / decrease change of the photoelectric sensor position passage time sequentially collected, and a small predetermined value from the strip end face position to the core part Since the position close to the end face that is as far as possible can be set as the detection position of the photoelectric sensor, the photoelectric sensor can effectively detect when the coating part extends unexpectedly toward the core part during strip processing. Therefore, it is possible to effectively prevent so-called coating biting failure at the time of crimping, and to provide a strip state inspection device with improved accuracy.

  In addition to detecting the passage time of the sheath as well as the passage time of the core wire part, even when wires with different wire diameters are set incorrectly, they can be detected effectively, and wasteful defective products are effectively discharged. Can be prevented.

  Furthermore, it is a configuration in which the quality of the strip state can be determined effectively with a single photoelectric sensor, and there is also an advantage that it can be easily provided by effectively controlling an apparatus having the same configuration as the conventional one.

  In addition, according to the photoelectric sensor detection position setting method of the electric wire processing machine of the present invention, the stripped electric wires are moved by a predetermined value in the axial direction of the strip, and a large number of photoelectric elements from the core wire region to the covering region are obtained. A sensing step for collecting the sensor position passage time, a strip end face position detection step for detecting the strip end face position from an increase / decrease change in the photoelectric sensor position passage time collected in the sensing step, and a strip detected in the strip end face position detection step A core wire passage time detection step and a covering portion passage time detection step for detecting the core wire passage time and the covering portion passage time from the collected photoelectric sensor position passage times on the end side and the opposite side from the end surface position, and a strip The end face proximity position that is separated from the strip end face position detected in the end face position detection process by a minute amount in the direction of the core wire. And a photoelectric sensor detection position setting step for setting the detection position of the photoelectric sensor in the same manner as described above. Collect the photoelectric sensor position passage time of many parts that reach the covering area, detect the strip end face position from the increase / decrease change of the photoelectric sensor position passage time collected sequentially, and detect the minute position from the strip end face position toward the core part. Since the position close to the end face as far as possible separated by a predetermined value can be set as the detection position of the photoelectric sensor, it is effective in the photoelectric sensor when the coating part expands unexpectedly on the core part side during strip processing. It is possible to detect, so as to effectively prevent so-called coating biting failure at the time of crimping, and to provide a strip state inspection device with improved accuracy.

  In addition to detecting the passage time of the sheath as well as the passage time of the core wire part, even when wires with different wire diameters are set incorrectly, they can be detected effectively, and wasteful defective products are effectively discharged. In addition, since it is possible to determine the quality of the strip state effectively with a single photoelectric sensor, there is an advantage that an apparatus having the same configuration as the conventional one can be used effectively and can be easily provided.

  Hereinafter, the embodiment of the present invention will be described with reference to the drawings. The both-end terminal crimping device 16 as an example of the wire processing machine in the present embodiment is also configured in the same manner as in FIG. The measuring unit 2 for sequentially feeding out the electric wires 1 and measuring the feed amount, the cutter unit 3 for cutting and stripping the electric wires 1, and the upstream and downstream sides of the electric supply direction P with respect to the cutter unit 3 Front side and rear side clamping devices 4 and 5 as gripping clamps arranged on the respective sides, and front side and rear side crimping terminals to the ends of the electric wires 1 gripped by the respective clamping devices 4 and 5 respectively. The terminal crimping units 6 and 7, the front and rear moving means 9 and 10 for moving the clamp devices 4 and 5 respectively, and the manufactured harness There is a provided on the mounting table 12 the wire discharge tray such as wire discharge portion issued structure.

  In addition, photoelectric sensors 14 and 15 for detecting the strip state of the covering portion 1b of the electric wire 1 in a non-contact manner are disposed corresponding to the passage paths of the electric wires 1 clamped by the respective clamping devices 4 and 5. As such photoelectric sensors 14 and 15, for example, a photoelectric switch or an optical fiber sensor including a projector and a light receiver that are spaced apart from each other with a predetermined interval in the vertical direction is used. And the strip state inspection apparatus having such photoelectric sensors 14 and 15 detects the passage time t when the core wire portion 1a of the stripped electric wire 1 passes through the positions of the photoelectric sensors 14 and 15, and sets in advance. It is controlled so as to determine whether the strip state is good or not based on whether or not it is within the range of the allowable value as compared with the passage time t of the determined determination value.

  Further, an operation unit operated by an operator is provided on one side of the mounting table 12, and the both-end terminal crimping device 16 is driven and controlled by a control device 17 as a control unit in accordance with an operation on the operation unit. It is configured.

  And it is set as the structure by which the harness which has a predetermined | prescribed electric wire length by which drive control was carried out similarly to the above, and the terminal was crimped | bonded by the both ends was manufactured one by one.

  Moreover, the automatic sensor adjustment function is incorporated in the control apparatus 17 in this embodiment, and this automatic sensor adjustment function moves the strip-processed electric wire 1 by a predetermined value in the axial direction of the core wire portion. Sensing control that collects the photoelectric sensor 14 and 15 position passage time t in a large number of parts from the 1a region to the covering portion 1b region, and the strip end face from the change in photoelectric sensor 14 and 15 position passage time t collected by this sensing control. Strip end surface position detection control for detecting the position D, and the collected photoelectric sensors 14 and 15 from the strip end surface position D on the core wire portion 1a side and the opposite covering portion 1b side, respectively, and the core wire portion passage time T1 from the position passage time t. Core wire part passage time detection control and cover part passage time detection control for detecting the covering part passage time T2, and the detected strip end Position D is configured to include a photoelectric sensor detection position setting control for setting a predetermined value spaced-apart surfaces adjacent position to the core part 1a directions at the detection position of the photoelectric sensor 14, 15 from.

  As the determination data setting method and the detection position setting method of the photoelectric sensors 14 and 15 in the strip state inspection apparatus, first, as shown in the flowchart of FIG. 1, the covering portion 1b of the electric wire 1 to be processed is first processed. Is stripped by the cutter unit 3 (step S11), and by the sensing control, as shown in FIG. 2, the position of the photoelectric sensor 14 is cut at a predetermined constant speed from the cutting position C in the core wire portion 1a. A position separated by a predetermined distance Sa (for example, 1 mm) in the direction passes. When the core wire portion 1a passes the position of the photoelectric sensor 14, the photoelectric sensor 14 is shielded from light and a detection signal is detected. The time detected by the light shielding is measured as the passage time t (step S12), and the passage time t is collected (step S13). That is, it is stored in the buffer.

  After sensing the first passage time t, the sensing position is changed by moving the front side clamp device 4 by a predetermined value (for example, 0.1 mm) in the axial direction of the electric wire 1, that is, in the cutting position B direction (step S14).

  Thereafter, it is determined whether or not sensing of 20 passage times t has been performed after the electric wire 1 has passed 10 round trips through the photoelectric sensor 14 position (step S15), and if 10 round trips have not elapsed, the process proceeds to step S12. Return.

  And by repeating the same, after sensing the passage time t by the photoelectric sensor 14, the sensing position is changed by moving the predetermined value (0.1 mm), as shown in FIG. 2 to FIG. Sensing is performed for 20 passage times t from the 1a region Sa to the covering portion 1b region Sb (sensing step).

  When the 10 reciprocal sensings are completed, the process proceeds to step S16, and the strip end surface position D is determined from the increase / decrease change of the 20 photoelectric sensor 14 position passage time t sequentially collected in the buffer by the strip end surface position detection control. Detect (Strip end face position detection step). For example, as shown in FIG. 5, silhouette data is obtained, and sequentially collected passage times t are short in the region Sa of the core wire portion 1a, long in the region Sb of the covering portion 1b, and in the vicinity of the strip end surface position D, There is a tendency that an intermediate level between the core line portion 1a region Sa and the covering portion 1b region Sb is detected, and the content of the increase / decrease change of each passing time t collected sequentially is differentiated to determine the position where the change is large as the strip end surface position D. It is a control method to detect.

  Further, by the core part passage time detection control, an average of each passage time t at the end side, that is, the front side corresponding to the core part 1a from the detected strip end surface position D is obtained by calculation, and the core part passage time T1 is obtained. Determine (core wire part passage time detection step). Further, by the cover part passage time detection control, an average of the respective passage times t at the cover part 1b corresponding position after the strip end surface position D is obtained by calculation, and the cover part passage time T2 is determined (cover part passage time detection). Process). In calculating the core wire passage time T1 and the covering portion passage time T2, data of the passage times t before and after the strip end surface position D are controlled to be excluded.

  Thereafter, as shown in FIG. 6, by the photoelectric sensor detection position setting control, the end face proximity position Sc separated from the detected strip end face position D by a minute predetermined value (for example, 0.5 mm) in the direction of the core wire portion 1a. Then, the detection position by the photoelectric sensor 14 is set (photoelectric sensor detection position setting step), and the obtained core wire portion passage time T1 is acquired and set as a determination value for determining whether the strip state is good or not (step S17). ).

  In the above description, the front-side photoelectric sensor 14 has been described. However, the rear-side photoelectric sensor 15 is similarly determined for setting the detection position by the photoelectric sensor 15 and determining whether the strip state is good or bad. A passing time t as a value is set.

  And at the time of electric wire processing, when the core part 1a of the electric wire 1 after the strip process clamped by the respective clamp devices 4 and 5 moves to the terminal crimping units 6 and 7, the photoelectric sensors 14 and 15 are positioned. Each passing time is detected, and the respective strip times such as normal, core wire portion 1a are cut off, strip miss, etc., depending on whether or not it is within the allowable range compared to the set passing time t of each judgment value. Control is performed to determine whether or not the quality is good.

  According to the both-end terminal crimping device 16 of the present embodiment, the stripped electric wire 1 is moved by a predetermined value (0.1 mm) in the axial direction of the cutting position B, and the core portion 1a region Sa to the covering portion 1b region. The photoelectric sensor 14 and 15 position passage time t of 20 parts leading to Sb are collected, and the strip end face position D is detected from the increase / decrease change of the passage time t of the photoelectric sensor 14 and 15 position collected sequentially. Since the end surface proximity position Sc that is as close as possible to the core wire portion 1a from the position D can be set as the detection position of the photoelectric sensors 14 and 15, the optimum position near the strip end surface position D can be set. If the core portion 1a can be sensed at the position, and the coating portion 1b expands unexpectedly on the core portion 1a side during strip processing, as shown in FIG. 14 and 15 effectively can be detected by the so-called coated chewing defects can be effectively prevented at the time of bonding, it can provide more accuracy strips state inspection apparatus, thereby the reliability of the sensor function. Therefore, there exists an advantage which can respond easily to the thinning of the electric wire 1 in recent years and the miniaturization of a terminal.

  In addition, when acquiring the determination data for determining the quality of the strip state, not only the core wire portion passage time T1 but also the covering portion passage time T2 is detected, so the input of the wire diameter and the like input for wire processing Even when the wire 1 having a wire diameter different from that of the data is erroneously set, it can be detected effectively, and wasteful defective products can be effectively prevented from being discharged.

  In addition, the single photoelectric sensor 14 or 15 can effectively determine the quality of the strip state, and can be provided at low cost, and can be easily provided by effectively controlling an apparatus having the same configuration as the conventional one. There is also.

  Moreover, since the outer diameter data of the electric wire 1 can also be obtained from the covering portion passage time T2 obtained at the time of sampling the determination data, the opening amount of the cutter is also reflected by reflecting the outer diameter data on the cutter opening amount of the cutter unit 3. It can be automatically detected, can effectively prevent unnecessary opening, and has the advantage of improving the operating speed.

  In addition, in the said embodiment, although the both-ends terminal crimping apparatus 16 is shown as an electric wire processing machine, another electric wire processing machine may be sufficient and it is not limited at all.

  Moreover, when acquiring the data of the photoelectric sensor 14 and 15 detection position and determination data, the core wire portion 1a region Sa, the covering portion 1b region Sb, the end surface proximity position Sc, the sensing position change amount, the number of times of sensing, and the like are not described in the embodiment. It is not limited, What is necessary is just to determine suitably according to the kind etc. of the electric wire 1 processed.
