[0003] Existing laser inspection equipment for wire drawing machines involves placing the laser inspection device in a position, aligning it with the metal wire in the wire drawing machine, and then starting the wire drawing machine for inspection. However, the laser inspection device can only detect one side of the metal wire at the position it is aligned with, while the other side cannot be inspected, thus limiting the scope of metal wire inspection. Summary of the Invention

[0012] Furthermore, the end of the pull plate away from the fixed plate is rotatably connected to the outer wall of the lower pressure plate, the bottom of the mounting column is in contact with the surface of the lower pressure plate, and there are two fixed plates, which are symmetrically arranged with the laser detector as the center.

[0013] Furthermore, the reinforcement mechanism includes a compression rod, an elastic plate is fixedly connected to the end of the compression rod, a bent rod is fixedly connected to the surface of the elastic plate, a reinforcement plate is fixedly connected to the end of the bent rod away from the elastic plate, a curved rod is fixedly connected to the surface of the elastic plate, and a locking post is fixedly connected to the end of the curved rod away from the elastic plate.

[0014] Furthermore, the end of the extrusion rod away from the elastic plate is fixedly connected to both sides of the extrusion rod. There are two reinforcing plates, which are symmetrically arranged around the laser detector. The surface of the clamping post is provided with a clamping groove. There are four pulling frames, which are divided into two groups of two at a time. The four pulling frames are symmetrically arranged around the laser detector.

[0015] Furthermore, the detection mechanism includes a toothed ring, with support grooves on both sides of the toothed ring. A lower support plate and an upper support plate are slidably connected to the inner walls of the support grooves. A slide is fixedly connected to the inner wall of the toothed ring, and a grooved ring is fixedly connected to the surface of the worktable.

[0016] Furthermore, the bottom of the power unit is fixedly connected to the surface of the workbench, the bottom of the lower support plate is fixedly connected to the surface of the workbench, the end of the upper support plate away from the gear ring is fixedly connected to the bottom of the inner wall of the support frame, the surface of the gear meshes with the surface of the gear ring, the surface of the slide is slidably connected to the inner wall of the groove ring, the surface of the slide has a pressing hole, the outer wall of the pressing plate contacts the inner wall of the pressing hole, and both ends of the base plate are fixedly connected to the inner wall of the slide.

[0017] The present invention has the following beneficial effects:

[0018] This invention utilizes a fixing mechanism. First, the operator picks up the laser detector, aligns the mounting column with the lower pressure plate, and presses the mounting column against the lower pressure plate. As the lower pressure plate is pressed, it moves downwards, compressing the tension rod. The tension rod then retracts downwards. Simultaneously, the downward movement of the lower pressure plate pulls one end of the pull plate downwards, while the other end of the pull plate moves towards each other, pulling the fixing plate towards itself. As the fixing plate moves, it pulls the telescopic plate towards itself, causing it to retract. During this movement, the fixing plate contacts both sides of the laser detector, effectively clamping both sides of the laser detector and thus fixing it in place, increasing the stability of the laser detector during testing.

[0019] This invention employs a reinforcement mechanism. When the telescopic plates move towards each other, they simultaneously drive the compression rods to move in the same direction. As the compression rods move, they compress the elastic plate, causing the middle portion of the elastic plate to bend. This bend pushes the curved rods to move towards each other, which in turn pushes the reinforcement plates towards each other, bringing them into contact with the other two sides of the laser detector, thus reinforcing the laser detector. Simultaneously, the bending of the middle portion of the elastic plate causes the curved rods to move towards each other. As the curved rods move, they cause the locking pins to move towards each other. During this movement, the ends of the locking pins contact the inner wall of the limiting ring. Upon contact, the ends of the locking pins compress the limiting ring, causing it to move away from each other. This movement pushes the limiting rods to move towards each other. The telescopic rods retract in a direction away from each other, simultaneously moving the pulling frame in the same direction. When the slot on the surface of the locking post moves to the inner wall of the limiting ring, the end of the locking post stops pressing against the limiting ring. At this point, the limiting ring, through the elasticity of the telescopic rod, fixes itself against the inner wall of the slot, thus limiting the locking post and the reinforcement and fixing mechanisms as a whole. When maintenance of the laser detector is required, the worker can pull the pulling frame in a direction away from each other. The locking post, through the elasticity of the elastic plate, resets the reinforcement and fixing mechanisms to their original positions, allowing for quick disassembly of the laser detector. The laser detector is effectively reinforced by two reinforcing plates, making it more stable during inspection. The combination of the limiting ring, telescopic rod, and pulling frame enables rapid fixing and disassembly of the laser detector.

[0020] This invention employs a detection mechanism. After the laser detector is fixed in place, it is powered on for scanning. A power unit is then activated, driving a gear to rotate. This rotation of the gear drives a gear ring, whose inner wall rotates on the surfaces of the lower and upper support plates. Simultaneously, the rotation of the gear ring drives a slide to rotate, which in turn rotates on the inner wall of a grooved ring. This rotation of the slide also causes the entire laser detector to rotate. A motor is then activated, driving a rotating shaft to rotate. This shaft, in turn, drives a wire-drawing shaft to rotate on the inner wall of a groove. The rotation of the wire-drawing shaft causes the metal wire to rotate, simultaneously drawing it. This effectively utilizes the gear ring to drive the slide to rotate on the inner wall of the grooved ring, enabling a comprehensive scan of the metal wire. This increases the comprehensiveness of the metal wire scan and overcomes the limitation of only detecting one side of the metal wire.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-10 As shown, the present invention is an optical inspection device for a wire drawing machine, including a worktable 1, support frames 2 fixedly connected to both ends of the worktable 1, a motor 3 fixedly connected to the bottom of the worktable 1, a rotating shaft 4 fixedly connected to the output end of the motor 3, a wire drawing rotating shaft 5 fixedly connected to the end of the rotating shaft 4 away from the motor 3, and a metal wire 6 disposed on the surface of the wire drawing rotating shaft 5, and also including;

[0037] The fixing mechanism 10 includes a lower pressure plate 14, and the mounting column 17 presses the lower pressure plate 14. When the lower pressure plate 14 is pressed, it will move downward. The bottom of the lower pressure plate 14 is fixedly connected to a force-bearing telescopic rod 15, and the force-bearing telescopic rod 15 is pressed. When the force-bearing telescopic rod 15 is pressed, it will retract downward. The end of the force-bearing telescopic rod 15 away from the lower pressure plate 14 is fixedly connected to a base plate 16.

[0038] The reinforcement mechanism 30 includes a limiting ring 37. During the movement of the locking pin 36, the end of the locking pin 36 contacts the inner wall of the limiting ring 37. When the end of the locking pin 36 contacts the inner wall of the limiting ring 37, it compresses the limiting ring 37. When compressed, the limiting ring 37 moves in a direction away from the locking ring. A limiting telescopic rod 38 is fixedly connected to the surface of the limiting ring 37. When the limiting ring 37 moves, it pushes the limiting telescopic rod 38 to retract in a direction away from the locking ring. The end of the limiting telescopic rod 38 is fixedly connected to the pulling frame 39, which will drive the pulling frame 39 to move away from each other. When the slot on the surface of the locking post 36 moves to the position of the inner wall of the limiting ring 37, the end of the locking post 36 has ended the compression of the limiting ring 37. At this time, the limiting ring 37 will fix the inner wall of the slot through the elasticity of the limiting telescopic rod 38, thereby limiting the locking post 36 and limiting the reinforcement mechanism 30 and the fixing mechanism 10 as a whole.

[0039] The testing mechanism 50 includes a power unit 55, and a gear 56 is fixedly connected to the output end of the power unit 55. After the laser detector 18 is fixed, the laser detector 18 is powered on for scanning, and then the power unit 55 is started to drive the gear 56 to rotate.

[0040] The bottom of the wire drawing shaft 5 is slidably connected to the inner wall of the rotating groove. The end of the shaft 4 is close to the bottom of the wire drawing shaft 5 and is fixedly connected to the bottom of the wire drawing shaft 5 through the bottom of the workbench 1. The surface of the wire drawing shaft 5 is in contact with the surface of the metal wire 6.

[0041] The fixing mechanism 10 includes a telescopic plate 11. When the fixing plate 12 moves, it pulls the telescopic plate 11 to retract towards each other. The end of the telescopic plate 11 is fixedly connected to the fixing plate 12, and the bottom of the fixing plate 12 is rotatably connected to the pull plate 13. When the pressure plate 14 moves downward, it pulls the end of the pull plate 13 downward, while the other end of the pull plate 13 moves towards each other. The surface of the pressure plate 14 is provided with mounting posts 17. First, the operator picks up the laser detector 18 and aligns the mounting posts 17 with the pressure plate 14. The end of the mounting post 17 away from the pressure plate 14 is fixedly connected to the laser detector 18. The fixing plate 12 effectively clamps the two sides of the laser detector 18, thereby achieving the effect of fixing the laser detector 18 and increasing the stability of the laser detector 18 during detection.

[0042] The end of the pull plate 13 away from the fixed plate 12 is rotatably connected to the outer wall of the lower pressure plate 14, and will pull the fixed plate 12 to move closer to each other. The bottom of the mounting column 17 contacts the surface of the lower pressure plate 14. There are two fixed plates 12, which are symmetrically arranged with the laser detector 18 as the center. During the movement of the fixed plate 12, it will contact the two sides of the laser detector 18.

[0043] The reinforcement mechanism 30 includes a compression rod 31. When the telescopic plates 11 move towards each other, the compression rod 31 moves in the same direction. An elastic plate 32 is fixedly connected to the end of the compression rod 31. A bent rod 33 is fixedly connected to the surface of the elastic plate 32, thus pushing the bent rod 33 towards the same direction. A reinforcement plate 34 is fixedly connected to the end of the bent rod 33 away from the elastic plate 32. When the bent rod 33 moves, it pushes the reinforcement plate 34 towards the same direction, causing the reinforcement plate 34 to contact the other two sides of the laser detector 18, thereby... The laser detector 18 is reinforced. A curved rod 35 is fixedly connected to the surface of the elastic plate 32. When the middle part of the elastic plate 32 bends, it will drive the curved rod 35 to move towards each other. A locking post 36 is fixedly connected to the end of the curved rod 35 away from the elastic plate 32. The laser detector 18 is effectively reinforced by the two reinforcing plates 34, making the laser detector 18 more stable during the detection process. At the same time, the laser detector 18 can be quickly fixed and quickly disassembled by the cooperation of the limiting ring 37, the limiting telescopic rod 38 and the pulling frame 39.

[0044] The end of the extrusion rod 31 away from the elastic plate 32 is fixedly connected to both sides of the extrusion rod 31. When the extrusion rod 31 moves, it will extrude the elastic plate 32. At this time, the middle part of the elastic plate 32 will bend when it is extruded. There are two reinforcing plates 34. The two reinforcing plates 34 are symmetrically arranged with the laser detector 18 as the center. The surface of the locking post 36 is provided with a locking groove. When the laser detector 18 needs to be maintained, the worker can pull the pulling frame 39 to move away from each other. At this time, the locking post 36 will reset the reinforcing mechanism 30 and the fixing mechanism 10 to their original positions through the elasticity of the elastic plate 32, so that the laser detector 18 can be quickly disassembled. When the curved rod 35 moves, it will drive the locking post 36 to move closer to each other. There are four pulling frames 39. They are divided into two groups of two at a time. The four pulling frames 39 are symmetrically arranged with the laser detector 18 as the center.

[0045] The testing mechanism 50 includes a gear ring 51. When the gear 56 rotates, it drives the gear ring 51 to rotate. Support grooves are provided on both sides of the gear ring 51. A lower support plate 52 and an upper support plate 53 are slidably connected to the inner walls of the support grooves. When the gear ring 51 rotates, its inner wall rotates on the surfaces of the lower support plate 52 and the upper support plate 53. A slide 54 is fixedly connected to the inner wall of the gear ring 51. When the gear ring 51 rotates, it drives the slide 54 to rotate. A grooved ring 57 is fixedly connected to the surface of the worktable 1. Simultaneously, the slide 54 rotates... When in motion, it rotates on the inner wall of the groove ring 57. Then, the motor 3 is started to drive the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it drives the wire drawing shaft 5 to rotate on the inner wall of the groove. When the wire drawing shaft 5 rotates, it drives the metal wire 6 to rotate and pull the metal wire 6 to draw it. This effectively drives the slide 54 to rotate on the inner wall of the groove ring 57 through the toothed ring 51 and performs a full-range scan of the metal wire 6. This increases the comprehensiveness of the scan of the metal wire 6 and solves the limitation of only detecting one side of the metal wire 6.

[0046] The bottom of the power unit 55 is fixedly connected to the surface of the workbench 1. The bottom of the lower support plate 52 is fixedly connected to the surface of the workbench 1. The end of the upper support plate 53 away from the gear ring 51 is fixedly connected to the bottom of the inner wall of the support frame 2. The surface of the gear 56 meshes with the surface of the gear ring 51. The surface of the slide 54 is slidably connected to the inner wall of the groove ring 57. The surface of the slide 54 is provided with a pressing hole. When the slide 54 rotates, it will drive the laser detector 18 to rotate as a whole. The outer wall of the pressing plate 14 contacts the inner wall of the pressing hole. The two ends of the base plate 16 are fixedly connected to the inner wall of the slide 54.

[0047] In use, the operator first picks up the laser detector 18, aligns the mounting post 17 with the lower pressure plate 14, and presses the lower pressure plate 14 with the mounting post 17. When the lower pressure plate 14 is pressed, it moves downwards and presses the force-bearing telescopic rod 15, causing the force-bearing telescopic rod 15 to retract downwards. As the lower pressure plate 14 moves downwards, it pulls one end of the pull plate 13 downwards, while the other end of the pull plate 13 moves towards each other, pulling the fixing plate 12 towards each other. When the fixing plate 12 moves, it pulls the telescopic plate 11 towards each other, causing it to retract. During the movement of the fixing plate 12, it contacts both sides of the laser detector 18. As the telescopic plate 11 moves towards each other, it drives the pressing rod 31 towards each other. As the compression rod 31 moves, it compresses the elastic plate 32. The elastic plate 32 bends in the middle under this pressure, pushing the bent rod 33 towards the closer objects. The bent rod 33, in turn, pushes the reinforcing plate 34 towards the closer objects, bringing it into contact with the other two sides of the laser detector 18, thus reinforcing the laser detector 18. Simultaneously, the bending of the middle portion of the elastic plate 32 causes the curved rod 35 to move towards the closer objects. This movement of the curved rod 35 also causes the locking pin 36 to move towards the closer objects. During this movement, the end of the locking pin 36 contacts the inner wall of the limiting ring 37. When the inner wall of the 7th section is compressed, the limiting ring 37 will be squeezed. When the limiting ring 37 is compressed, it will move in a direction away from the limiting ring. As the limiting ring 37 moves, it will push the limiting telescopic rod 38 to retract in a direction away from the limiting ring, simultaneously causing the pulling frame 39 to move in a direction away from the limiting ring. When the slot on the surface of the locking post 36 moves to the position of the inner wall of the limiting ring 37, the end of the locking post 36 has finished compressing the limiting ring 37. At this time, the limiting ring 37 will fix itself to the inner wall of the slot through the elasticity of the limiting telescopic rod 38, thereby limiting the locking post 36 and the reinforcement mechanism 30 and the fixing mechanism 10 as a whole. When maintenance of the laser detector 18 is required, the worker can pull the pulling frame 39 to move in a direction away from the limiting ring. The locking post 36, through the elasticity of the elastic plate 32, will cause the reinforcing mechanism 30 and the fixing mechanism 10 to return to their original positions as a whole, thereby allowing for quick disassembly of the laser detector 18. After the laser detector 18 is fixed, it is powered on for scanning. At this time, the power unit 55 is started to drive the gear 56 to rotate. When the gear 56 rotates, it will drive the gear ring 51 to rotate. When the gear ring 51 rotates, its inner wall will rotate on the surface of the lower support plate 52 and the upper support plate 53. When the gear ring 51 rotates, it will drive the slide 54 to rotate. At the same time, when the slide 54 rotates, it will rotate on the inner wall of the groove ring 57. The rotation of the slide 54 will drive the laser detector 18 to rotate as a whole. Then, the motor 3 is started to drive the rotating shaft 4 to rotate.When the rotating shaft 4 rotates, it drives the drawing shaft 5 to rotate within the rotating groove. As the drawing shaft 5 rotates, it drives the metal wire 6 to rotate, simultaneously drawing the metal wire 6.
