[0007] Furthermore, the fixed middle plate is fixedly connected to the surface of the layer plate frame, and the sliding middle plate is slidably connected to the layer plate frame through a sliding groove.

[0008] Furthermore, one end of the elastic rope away from the electronic lock is fixedly connected to the sliding middle plate, and the side surface of the sliding middle plate is connected to the electric push rod located above the moving sleeve through a right-angle rod.

[0009] Furthermore, a laser rangefinder is arranged inside the hole of any of the perforated racks, and the two perforated racks are located at the same height.

[0010] Furthermore, the straightening and anti-breaking component also includes a penetration rod and a wire ring box. The fixed middle plate and the sliding middle plate are both provided with a penetration rod, and the bottom of the penetration rod is fixed with a wire ring box.

[0011] Furthermore, the straightening and anti-breaking component also includes a rotating gear ring, a transmission gear and a micro motor. The side of the wire passing ring box is rotatably connected to the rotating gear ring, and the outer side of the rotating gear ring is meshedly connected to the transmission gear, and the side of the transmission gear is connected to the micro motor.

[0012] Furthermore, the micro motor is embedded in the wire passing ring box, and the central axis of the rotating gear ring coincides with the central axis of the wire passing ring box.

[0013] Furthermore, the straightening and anti-breaking component also includes a telescopic slide plate, and the interior of the wire passing ring box is slidably connected to the telescopic slide plate.

[0014] Furthermore, the telescopic slide plate is distributed inside the wire passing ring box in a ring shape, and the surface of the telescopic slide plate is rotatably connected to the rotating gear ring through a connecting shaft.

[0015] Furthermore, the straightening and anti-breaking component also includes a light hole ring, and the bottom of the wire ring box is connected to the light hole ring.

[0016] The present invention provides a laser measuring device for alloy wire length, which has the following beneficial effects: 1. The alloy wire length laser measuring device detects the tension value when the two ends of the wire are clamped away from each other to make it straight through the tension sensor in real time, and stops the straightening operation of the wire in time when the upper limit of the tension value is reached, which is conducive to preventing the wire from breaking due to excessive force in the straightening step. The elastic rope is used instead of the wire as a tension transmission member, and the upper limit of the tension value that it can withstand is higher. In addition, the distance between the sliding middle plate and the fixed middle plate and the excessive fall of the middle section of the elastic action surface can affect the straightening and length measurement of the wire.

[0017] 2. In the alloy wire length laser measuring device, during the straightening process, the wire is gradually straightened and generates an upward force, so that the wire ring box is subjected to force, so that the penetration rod is lifted up and passes through the fixed middle plate and the sliding middle plate, thereby adjusting the height of the wire ring box and the light hole ring in disguised form, and the laser beam emitted by the laser rangefinder can pass through the light hole ring to obtain the wire length. If the distance dimension measured by the laser rangefinder shows the fixed length dimension between the light hole ring and the induction plate, it means that the wire has not been straightened, thereby ensuring that the wire length measurement result is measured when the wire is in a straightened state.

[0018] 3. In the alloy wire length laser measuring device, after the wire passes through the wire ring box, its two ends are clamped, and the micro motor drives the transmission gear to rotate the rotating gear ring, so that the telescopic slide plate is telescoped inside the wire ring box, which is conducive to adjusting the inner diameter size of the wire ring box, so that the inner diameter size of the wire ring box is adapted to the wire diameter, so that the wire coincides with the central axis of the wire ring box after being straightened. At this time, the four clamped positions of the wire must be on the same straight line, thereby further ensuring that the wire is measured in a straightened state through multi-point clamping and straight line detection.

[0019] 4. The alloy wire length laser measuring device places the two ends of the alloy wire to be measured in two end boxes respectively. Due to the characteristic of the alloy wire that the shorter the length, the less likely it is to bend, the end of the wire that extends into the end box can remain straight. When the wire is straightened, the distance between the two sensing plates measured by the laser rangefinder is the length of the wire after straightening, which is conducive to including the clamped end of the wire in the length measurement range and ensuring that the clamped part is straight, thereby improving the accuracy of length measurement.

DETAILED DESCRIPTION

[0022] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figure 1-Figure 5 As shown, the present invention provides a technical solution: a laser measuring device for alloy wire length, comprising an operating platform 1, a wire clamping moving component 5 and a straightening and anti-breaking component 7, a fixed bracket 2 is fixed to the surface end of the operating platform 1, and a screw rod 3 is rotatably connected to the surface of the operating platform 1, the end of the screw rod 3 is connected to a driving motor 4, and a moving sleeve 9 is sleeved on the surface of the screw rod 3, a total of two groups of wire clamping moving components 5 are provided and are respectively connected to the moving sleeve 9 and the top of the fixed bracket 2, the wire clamping moving component 5 comprises a perforated frame 501, an end box 502, a sensing plate 503, an electric push rod 504 and a wire pressing plate 505, the top of the perforated frame 501 is fixed with an end box 502, and the back of the end box 502 is fixed with a sensing plate 503, the top of the end box 502 is fixed with an electric push rod 504, and the bottom end of the electric push rod 504 penetrates into the end box 502 and is simultaneously connected to the wire pressing plate 505, and the upper sides of the screw rod 3 are provided There is a layer plate frame 6, and a slide groove 8 is opened on the surface of the layer plate frame 6. The straightening and anti-breaking component 7 is arranged on the surface of the layer plate frame 6. The straightening and anti-breaking component 7 includes a fixed middle plate 701, a sliding middle plate 702, a tension sensor 703, an electronic lock 704 and an elastic rope 705. The fixed middle plate 701 is distributed parallel to one side of the fixed middle plate 701, and the tension sensor 703 is embedded in the fixed middle plate 701. The end of the tension sensor 703 is connected to the electronic lock 704, and the surface of the electronic lock 704 is connected to the elastic rope 705. The fixed middle plate 701 is fixedly connected to the surface of the layer plate frame 6, and the sliding middle plate 702 is slidably connected to the layer plate frame 6 through the slide groove 8. The end of the elastic rope 705 away from the electronic lock 704 is fixedly connected to the sliding middle plate 702, and the side of the sliding middle plate 702 is connected to the electric push rod 504 located above the moving sleeve 9 through a right-angle rod; The specific operation is as follows: the two ends of the alloy wire to be measured are placed in the two end boxes 502 respectively. Due to the characteristic of the alloy wire that the shorter the length, the less likely it is to bend, the end of the wire extending into the end box 502 can remain straight. When the end of the wire contacts the induction plate 503, the electric push rod 504 extends so that the wire pressing plate 505 clamps the end of the wire to keep it straight. Then the driving motor 4 drives the screw rod 3 to rotate so that the movable sleeve 9 carries the hole frame 501 on the top thereof away from the other hole frame 501, so that the two ends of the wire material gradually move away from each other and gradually straighten; When the perforated frame 501 on the top of the movable sleeve 9 moves, the sliding middle plate 702 is driven by the right-angle rod to slide along the inside of the slide groove 8 on the surface of the layer frame 6, so that the distance between the sliding middle plate 702 and the fixed middle plate 701 becomes larger. At this time, the elastic rope 705 is gradually stretched until it reaches the limit length. At the same time, the tension sensor 703 senses the tension value. After the tension value exceeds the upper threshold, the electronic lock 704 releases the elastic rope 705, and the movable sleeve 9 stops moving. The upper threshold of the tension value is the upper limit of the tension that the wire can withstand. The specific value of the tension value can be obtained through testing, and the upper limit of the tension that the elastic rope 705 can withstand is higher than the upper limit of the tension value of the wire test. Therefore, the tension value when the two ends of the wire are clamped away from each other to make it straight is detected in real time through the tension sensor 703, and the straightening operation of the wire is stopped in time when the upper limit of the tension value is reached, which is helpful to prevent breakage due to excessive force in the straightening step. The elastic rope 705 is used instead of the wire as a tension transmission member, and the upper limit of the tension value that it can withstand is higher. In addition, the straightening and length measurement of the wire can be affected by the size of the distance between the sliding middle plate 702 and the fixed middle plate 701 and the excessive falling of the middle section of its own elastic action surface.

[0024] like Figure 1-Figure 5 As shown, a laser rangefinder 10 is disposed inside the hole of any hole-bearing frame 501, and the two hole-bearing frames 501 are located at the same height; The specific operation is as follows: after the wire is straightened, the end portion of the wire located inside the end box 502 can remain straight due to the characteristic of the alloy wire that the shorter the length, the less likely it is to bend. Therefore, the distance between the two sensing plates 503 measured by the laser rangefinder 10 is the length of the wire after straightening, which is conducive to incorporating the clamped end portion of the wire into the length measurement range and ensuring that the clamped portion is straight, thereby helping to improve the accuracy of length measurement.

[0025] like Figure 1-Figure 5As shown, the straightening and anti-breaking component 7 also includes a penetration rod 706 and a wire passing ring box 707. The fixed middle plate 701 and the sliding middle plate 702 are both penetrated with the penetration rod 706, and the bottom of the penetration rod 706 is fixed with the wire passing ring box 707. The straightening and anti-breaking component 7 also includes a rotating gear ring 708, a transmission gear 709 and a micro motor 710. The side of the wire passing ring box 707 is rotatably connected with the rotating gear ring 708, and the outer side of the rotating gear ring 708 is meshedly connected with the transmission gear 709, and the side of the transmission gear 709 is connected with the micro motor 710. The micro motor 710 is embedded in the wire passing ring box 707, and the central axis of the rotating gear ring 708 coincides with the central axis of the wire passing ring box 707. The straightening and anti-breaking assembly 7 also includes a telescopic slide 711, and the inner part of the wire passing ring box 707 is slidably connected with the telescopic slide 711. The telescopic slide 711 is distributed in the inner part of the wire passing ring box 707 in a ring shape, and the surface of the telescopic slide 711 is rotatably connected with the rotating gear ring 708 through a connecting shaft. The straightening and anti-breaking assembly 7 also includes a light hole ring 712, and the bottom of the wire passing ring box 707 is connected with the light hole ring 712; The specific operation is as follows: after the wire passes through the wire ring box 707, both ends of the wire are clamped, and the micro motor 710 drives the transmission gear 709 to rotate the rotating gear ring 708, so that the telescopic slide plate 711 is telescoped inside the wire ring box 707, which is conducive to adjusting the inner diameter size of the wire ring box 707, so that the inner diameter size of the wire ring box 707 is adapted to the wire diameter, so that the wire coincides with the central axis of the wire ring box 707 after being straightened; During the straightening process, the wire is gradually straightened and an upward force is generated, so that the wire ring box 707 is subjected to force, so that the penetration rod 706 is lifted up and passes through the fixed middle plate 701 and the sliding middle plate 702, thereby adjusting the height of the wire ring box 707 and the light hole ring 712 in disguised form. After the wire is straightened, the four clamped points on the surface of the wire are in the same straight line, and the central axis of the light hole ring 712 coincides with the central axis of the laser rangefinder 10, and the laser beam emitted by the laser rangefinder 10 is able to pass through the light hole ring 712 to obtain the length of the wire. If the spacing dimension measured by the laser rangefinder 10 shows the fixed length dimension between the light hole ring 712 and the sensing plate 503, it means that the wire has not been straightened yet, thereby ensuring that the wire length measurement result is measured when the wire is in a straightened state.

[0026] In summary, when the alloy wire length laser measuring device is used, first, the wire passes through the wire ring box 707 and its two ends are placed inside the two end boxes 502. Since the alloy wire is less likely to bend as its length shortens, the portion of the wire end extending into the end box 502 can remain in a straight line. When the wire end contacts the induction plate 503, the electric push rod 504 extends so that the wire pressing plate 505 clamps the wire end in a straight line. The micro motor 710 drives the transmission gear 709 to rotate the rotating gear ring 708, so that the telescopic slide plate 711 is telescoped inside the wire ring box 707, which is conducive to adjusting the inner diameter size of the wire ring box 707, so that the inner diameter size of the wire ring box 707 is adapted to the wire diameter. Then the driving motor 4 drives the screw rod 3 to rotate so that the movable sleeve 9 carries the perforated frame 501 on its top away from the other perforated frame 501, so that the two ends of the wire material slowly move away and gradually straighten. At the same time, when the perforated frame 501 on the top of the movable sleeve 9 moves, it drives the sliding middle plate 702 to slide along the inside of the slide groove 8 on the surface of the layer frame 6 through the right-angle rod, so that the distance between the sliding middle plate 702 and the fixed middle plate 701 becomes larger. At this time, the elastic rope 705 is gradually stretched until it reaches the limit length. At the same time, the tension sensor 703 senses the tension value. After the tension value exceeds the upper threshold value, the electronic lock 704 releases the elastic rope 705, and the movable sleeve 9 stops moving to prevent the wire material from being broken. In the above steps, the wire is gradually straightened and an upward force is generated, so that the wire ring box 707 is subjected to force, so that the penetration rod 706 is lifted up and passes through the fixed middle plate 701 and the sliding middle plate 702, thereby adjusting the height of the wire ring box 707 and the light hole ring 712 in disguised form. When the wire tension value does not reach the upper limit, and the laser beam emitted by the laser rangefinder 10 is able to pass through the light hole ring 712 to obtain the wire length, it means that the wire has been straightened at this time. If the spacing size measured by the laser rangefinder 10 shows the fixed length size between the light hole ring 712 and the sensor plate 503, it means that the wire has not been straightened yet.
