[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This intelligent fastener defect rate identification device, through the setting of a material picking mechanism, a top block, and a laser rangefinder sensor, achieves intelligent identification of defective workpieces by setting up a material picking mechanism, a top block, and a laser rangefinder sensor. When the workpiece moves in the conveyor channel, the laser rangefinder sensor emits a laser beam. After the laser beam hits the workpiece, it is reflected back and received by the laser rangefinder sensor, which detects the distance to the bottom of the workpiece and thus determines the length of the workpiece. When a defective workpiece is detected, it moves to the top block, and the electric push rod extends to push the top block upward. The top block pushes the defective workpiece upward until the top of the workpiece contacts the suction cup. At the same time, the vacuum pump draws suction from the suction cup through the air pipe, creating a negative pressure to adsorb the workpiece. In conjunction with the material picking motor, the vertical rod rotates, and the vertical rod drives the suction cup and workpiece to rotate to the top of the collection box via the crossbeam. The vacuum pump stops adsorption, allowing the defective workpiece to fall into the collection box for collection, thus achieving the effect of automatically rejecting and collecting defective workpieces.

[0015] 2. This fastener defect rate intelligent identification device, by setting a support block screw hole and a screw rod, drives the screw rod to rotate through the handle. The screw rod rotates in the screw hole, driving the support seat to move back and forth. The support seat drives the bottom slider to move in the slide groove, and drives the belt conveyor above to move back and forth. The belt conveyor drives the conveyor plate to move back and forth, and adjusts the distance between the conveyor plate and the frame, that is, the distance of the conveying channel. It can be used for the inspection of workpieces of different specifications, increasing the applicability of the equipment. Attached Figure Description

A material handling mechanism 2 is installed on the upper surface of the frame 1 to remove identified defective products. A base 3 is connected to the bottom edge of the frame 1 near the rear side. A belt conveyor 4 is installed on the front side of the frame 1. The belt conveyor 4 is a common type of conveyor. A conveyor plate 5 is connected to the surface of the belt conveyor 4. A push plate 6 is connected to the upper surface of the conveyor plate 5 to push the workpiece 7 to move. The workpiece 7 is movably placed between the conveyor plate 5 and the frame 1. A bracket 8 is connected to the bottom of the frame 1 to install a laser rangefinder sensor 9 and a top block 10, and to reinforce the frame 1. The laser rangefinder sensor 9 is installed on the upper surface of the bracket 8. The actual model is selected based on the height distance from the bottom of the workpiece 7 to the laser emission point of the laser rangefinder 9. When the workpiece 7 moves above the laser rangefinder 9 in the conveying channel, the laser rangefinder 9 emits a laser beam. After the laser beam hits the workpiece 7, it is reflected back and received by the laser rangefinder 9. The distance to the bottom of the workpiece 7 is detected, and the length of the workpiece 7 is obtained. A top block 10 is installed on the upper surface of the bracket 8 on one side of the laser rangefinder 9 to push the workpiece 7 upward in the conveying channel. An electric push rod 11 is connected to the bottom of the top block 10. The electric push rod 11 is installed at the bottom of the bracket 8, and the actual model of the electric push rod 11 is selected according to the stroke required to push the top block 10 upward.

[0023] The material handling mechanism 2 includes a vertical rod 21, which is round. A first bearing 22 is connected between the bottom of the vertical rod 21 and the frame 1. A main gear 23 is connected to the bottom of the vertical rod 21. A secondary gear 24 is meshed with one side of the main gear 23. The main gear 23 and the secondary gear 24 mesh. The vertical rod 21 is rotatably connected to the material handling motor 25 via the main gear 23 and the secondary gear 24. The material handling motor 25 is connected below the secondary gear 24. The material handling motor 25 is installed at the bottom of the frame 1, and its shaft is connected to the secondary gear 24. The material handling motor 25 is essentially a motor with forward and reverse rotation circuits. A crossbeam 26 is vertically connected to the top of the vertical rod 21. A suction cup 27 is connected to the bottom of the crossbeam 26. The suction cup 27 is used for vacuum adsorption of the workpiece 7. A vent pipe 28 is connected to the top of the suction cup 27. A vacuum pump 29 is connected to the end of the vent pipe 28 that is away from the suction cup 27. A control box is also provided on one side of the base 3, which serves as the main control center for each electrical device and controls the normal operation of each electrical device.

[0024] Specifically, the bottom of the vertical rod 21 is rotatably connected to the frame 1 via the first bearing 22. The material handling motor 25 drives the vertical rod 21 to rotate. The vertical rod 21 drives the suction cup 27 and the workpiece 7 to rotate above the collection box 20 via the crossbeam 26. The vacuum pump 29 is installed on the upper surface of the frame 1. The suction cup 27 is connected to the vacuum pump 29 via the air pipe 28. The suction cup 27 is directly above the workpiece 7. When the top block 10 pushes the workpiece 7 upward, the vacuum pump 29 starts to perform suction. When the top block 10 does not move upward and the workpiece 7 on the suction cup 27 falls into the collection box 20, the vacuum pump 29 does not work. The suction force of the vacuum pump 29 must meet the weight of the workpiece 7.

[0025] Furthermore, the top block 10 has an L-shaped longitudinal section. The bottom of the top block 10 is connected to the telescopic end of the electric push rod 11. The top block 10 is located directly below the workpiece 7. The electric push rod 11 extends and pushes the top block 10 upward. The top block 10 pushes the defective workpiece 7 upward until the top of the workpiece 7 contacts the suction cup 27, lifting the workpiece 7 upward and being attracted by the suction cup 27. The start time of the electric push rod 11 and the laser range sensor 9 corresponds to the conveying speed of the belt conveyor 4. The control box adjusts to ensure the time interval between the electric push rod 11 and the laser range sensor 9, so that each workpiece 7 is intelligently identified by the laser range sensor 9.

[0026] Furthermore, a through groove 19 is provided on the upper surface of the frame 1 on one side of the vertical rod 21. A collection box 20 is provided inside the through groove 19. The collection box 20 is movably connected to the through groove 19. The inner cavity of the collection box 20 is divided to collect workpieces 7 that are too long and too short respectively, and to classify and collect defective products. The collection box 20 can be removed from the through groove 19 at will.

[0027] Furthermore, there are several conveyor plates 5, which are arranged at equal intervals on the belt surface of the belt conveyor 4. There is a gap between the conveyor plates 5 and the frame 1 to form a conveying channel. The workpiece 7 is placed inside the conveying channel. There is a gap between adjacent conveyor plates 5 to facilitate the movement of the conveyor plates 5 on both sides of the belt conveyor 4.

[0028] Furthermore, the length of the push plate 6 is greater than the length of the conveyor plate 5, and the push plate 6 extends beyond the conveying channel to the top of the frame 1. While the belt conveyor 4 is conveying, it drives the conveyor plate 5 to move, and the conveyor plate 5 drives the push plate 6 to move. The push plate 6 pushes the workpiece 7 to move within the conveying channel.

[0029] Furthermore, a groove 12 is provided on the upper surface of the base 3, and a support seat 13 is connected to the bottom of the belt conveyor 4. A slider 14 is connected to the bottom of the support seat 13, and a screw hole 15 is provided through the middle of the support seat 13. A screw 16 is installed through the screw hole 15, and the outer diameter of the screw 16 is adapted to the inner diameter of the screw hole 15. A handle 18 is connected to the front side of the screw 16, and a second bearing 17 is connected between the rear side of the screw 16 and the bracket 8. The screw 16 passes through the screw hole 15 and the support seat 13 to form a threaded connection with the support seat 13. 6 is rotatably connected to the bracket 8 via the second bearing 17. The slider 14 has a longitudinal section of T-shape. The slider 14 is locked inside the slide groove 12 and forms a sliding connection with the base 3. The screw 16 is driven to rotate by the handle 18. The screw 16 rotates in the screw hole 15 and drives the support seat 13 to move back and forth. The support seat 13 drives the slider 14 at the bottom to move in the slide groove 12 and drives the belt conveyor 4 above to move back and forth. The belt conveyor 4 drives the conveyor plate 5 to move back and forth, adjusting the distance between the conveyor plate 5 and the frame 1, that is, the distance of the conveying channel.

[0030] The usage method of this embodiment is as follows: When the user is actually performing length dimension inspection on the workpiece 7, firstly, adjust the width of the conveying channel according to the outer diameter of the workpiece 7 to be inspected. The screw 16 is driven to rotate by the rotating handle 18. The screw 16 rotates in the screw hole 15, driving the support base 13 to move back and forth. The support base 13 drives the bottom slider 14 to move in the slide groove 12, and drives the belt conveyor 4 above to move back and forth. The belt conveyor 4 drives the conveyor plate 5 to move back and forth. Adjust the distance between the conveyor plate 5 and the frame 1 so that the width of the conveying channel is greater than the outer diameter of the workpiece 7 but less than the outer diameter of the end of the workpiece 7. Then, place the workpiece 7 in the conveying channel, with the end of the workpiece 7 above the conveyor plate 5 and the frame 1. Start the belt conveyor 4. The belt conveyor 4 drives the conveyor plate 5 to move while conveying. The conveyor plate 5 drives the push plate 6 to move. The push plate 6 pushes the workpiece 7 to move in the conveying channel. When the workpiece 7 moves in the conveying channel... When the workpiece 7 reaches above the laser rangefinder 9, the laser rangefinder 9 emits a laser beam. The laser beam hits the workpiece 7 and is reflected back, which is received by the laser rangefinder 9. The distance to the bottom of the workpiece 7 is detected, and the length of the workpiece 7 is obtained. This enables intelligent identification of defective workpiece 7. When a defective workpiece is detected, it continues to move to the position above the top block 10. The electric push rod 11 extends and pushes the top block 10 upward. The top block 10 pushes the defective workpiece 7 upward until the top of the workpiece 7 contacts the suction cup 27. At the same time, the vacuum pump 29 draws suction from the suction cup 27 through the air pipe 28, causing the suction cup 27 to generate negative pressure to adsorb the workpiece 7. Then, the material handling motor 25 starts and drives the auxiliary gear 24 to rotate. The auxiliary gear 24 drives the main gear 23 to rotate. The main gear 23 drives the vertical rod 21 to rotate. The vertical rod 21 drives the suction cup 27 and the workpiece 7 to rotate above the collection box 20 through the crossbeam 26. At this time, the vacuum pump 29 stops adsorption, allowing the defective workpiece 7 to fall into the collection box 20 for collection.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
