Description

A fastener inspection and sorting device Technical Field

[0001] This utility model relates to the field of fastener detection and sorting technology, and in particular to a fastener detection and sorting device. Background Technology

[0002] In modern industrial manufacturing systems, fasteners, as basic components connecting various mechanical parts, directly affect the structural safety and operational reliability of key fields such as automobiles, aerospace, and construction. From raw material formation to finished product output, strict testing and precise sorting of indicators such as thread accuracy, surface defects, and dimensional tolerances are the core links to ensure the stability of fastener product quality.

[0003] Currently, existing fastener inspection and sorting equipment generally relies on manual operation for the workpiece loading process. Operators need to place the fasteners to be inspected one by one onto the conveyor mechanism. This method is not only labor-intensive and inefficient, but also difficult to match the high-speed operation requirements of automated inspection equipment. Furthermore, manual placement is prone to problems such as omissions or misplacements due to operator fatigue or negligence, which can lead to frequent image acquisition blind spots or dimensional measurement errors at the inspection station, seriously affecting the inspection accuracy. Therefore, we propose a fastener inspection and sorting device. Summary of the Invention

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As shown in Figures 1 to 5: A fastener inspection and sorting device includes a workbench 1. Two through slots 2 for discharging materials are formed on the upper surface of the workbench 1. A conveyor belt 3 for conveying fasteners for inspection and sorting is installed on the inner wall of the workbench 1. An automatic feeding assembly 4 is provided above the workbench 1 for automatically placing fasteners on the surface of the conveyor belt 3. The automatic feeding assembly 4 includes an intermittent discharge structure and a guiding structure for discharging fasteners. The discharge structure includes a support frame 401 fixedly connected to the upper surface of the workbench 1. A first motor 402 is installed on the inner wall of the support frame 401. An eccentric wheel 403 is fixedly connected to the output end of the first motor 402. A limit rod 404 is fixedly connected to the inner wall of the top of the support frame 401. A moving block 405 is slidably connected to the outer surface of the limit rod 404. A first spring 406 is sleeved on the outer surface of the limit rod 404. The two ends of the first spring 406 are respectively connected to the moving block 405. The outer surface of the moving block 405 is fixedly connected to the inner wall of the support frame 401. The upper surface of the moving block 405 is fixedly connected to the storage box 407, and the bottom surface of the storage box 407 is slidably connected to the upper surface of the support frame 401. The bottom surface of the storage box 407 is fixedly connected to the connecting plate 408. The first motor 402 is started to drive the eccentric wheel 403 to rotate. When the protruding part of the eccentric wheel 403 rotates to contact the connecting plate 408, the storage box 407 will move backward and the first spring 406 will be compressed. When the protruding part of the eccentric wheel 403 rotates away from the connecting plate 408, the first spring 406 will immediately reset and push the storage box 407 to reset, thereby causing the storage box 407 to vibrate. This allows a small number of fasteners inside the storage box 407 to be discharged to the outside through vibration. The first motor 402 rotates intermittently, which can prevent too many fasteners discharged from the storage box 407 from causing blockage inside the fixed chamber 409.

[0027] As shown in Figures 1 to 5: The material guiding structure includes a fixed chamber 409 fixedly connected to the outer surface of the support frame 401. A first guide plate 410 is fixedly connected to the inner wall of the fixed chamber 409. A second guide plate 411 is slidably connected to the inner wall of the fixed chamber 409. A movable plate 412 is fixedly connected to the outer surface of the second guide plate 411, and the outer surface of the movable plate 412 is slidably connected to the inner wall of the fixed chamber 409. A second spring 413 is fixedly connected to the other side of the movable plate 412, and the other end of the second spring 413 is fixedly connected to the inner wall of the fixed chamber 409. An L-shaped plate 414 is fixedly connected to the outer surface of the second guide plate 411, and the outer surface of the L-shaped plate 414 is slidably connected to the inner wall of the fixed chamber 409. A guide rail 415 is provided below the fixed chamber 409, and the side of the guide rail 415 near the support frame 401 is fixedly connected to the outer surface of the support frame 401. The first guide plate 410 and the second guide plate 411 are connected to the inner wall of the fixed chamber 409. The gap between the flow plates 411 is just right to match the thicker end of the fastener, allowing the fastener to fall from the first flow plate 410 and the second flow plate 411. When the fastener falls onto the surface of the guide rail 415, the thicker end of the fastener will rest on the top of the guide rail 415, and the thinner end of the fastener will fall through the gap in the guide rail 415, keeping the fastener in a vertical position. This facilitates the subsequent placement of the fastener onto the outer surface of the conveyor belt 3. When the protrusion of the eccentric wheel 403 rotates to contact the L-shaped plate 414, it will cause the second flow plate 411 to move towards the moving plate 412 and compress the second spring 413. When the protrusion of the eccentric wheel 403 moves away from the L-shaped plate 414, the second spring 413 will immediately rebound and drive the second flow plate 411 to reset, thereby achieving the effect of moving the second flow plate 411 and preventing the fastener from getting stuck between the first flow plate 410 and the second flow plate 411 and causing blockage.

[0028] As shown in Figures 1, 2, 3, and 5, the material guiding structure also includes a support plate 416 fixedly connected to the outer surface of the support frame 401. A second motor 417 is installed on the bottom surface of the support plate 416. A first rotating rod 418 is fixedly connected to the output end of the second motor 417, and the outer surface of the first rotating rod 418 is rotatably connected to the inner wall of the support plate 416. A second rotating rod 419 is rotatably connected to the upper surface of the support plate 416. A conveyor belt 420 is sleeved on the outer surface of the first rotating rod 418 and the second rotating rod 419. Two moving rods 421 are fixedly connected to the outer surface of the conveyor belt 420. When the second motor 417 is started, it drives the first rotating rod 418 to rotate. When the first rotating rod 418 rotates, the conveyor belt 420 will rotate around the first rotating rod 418 and the second rotating rod 419, thereby driving the two moving rods 421 to move. The moving rods 421 push the fasteners on the surface of the guide rail 415 to move to the opening of the guide rail 415 and fall down, thereby achieving the effect of automatic material feeding.

[0029] As shown in Figures 1, 2, 3, and 5: An infrared sensor 422 is fixedly connected to one end of the guide rail 415 away from the support frame 401. The sensing end of the infrared sensor 422 is located below the fastener in the horizontal movement direction. When the sensing end of the infrared sensor 422 senses that a fastener has fallen onto the surface of the conveyor belt 3, it will send a signal to the terminal to stop the second motor 417 for a few seconds, and then restart the second motor 417, so that the fasteners falling onto the surface of the conveyor belt 3 are spaced a distance apart, which facilitates the subsequent detection and sorting of the fasteners.

[0030] As shown in Figures 1 and 6: Above the workbench 1, there is also a detection and sorting assembly 5 for detecting and sorting fasteners. The detection and sorting assembly 5 includes a detector 501 installed on the upper surface of the workbench 1 and a vertical plate 502 fixedly connected to the upper surface of the workbench 1. An electric telescopic rod 503 is installed on the outer surface of the vertical plate 502. A push plate 504 is fixedly connected to the telescopic end of the electric telescopic rod 503. A V-shaped guide plate 505 is provided on one side of the push plate 504. The bottom surface of the V-shaped guide plate 505 is flush with the workbench. The upper surface of 1 is fixedly connected. The detector 501 can detect the quality of the fastener. When the detector 501 detects that the fastener is bad, the electric telescopic rod 503 will push the push plate 504 to push the fastener to the rear inclined surface of the V-shaped guide plate 505. Then the electric telescopic rod 503 will immediately reset. When the detector 501 detects that the fastener is good, the electric telescopic rod 503 will not run, so that the fastener moves according to the front inclined surface of the V-shaped guide plate 505, thereby achieving the effect of fastener detection and sorting.

[0031] As shown in Figures 1 and 6: A baffle plate 6 is fixedly connected to the upper surface of the workbench 1, and the baffle plate 6 has a certain tilt angle. Two collection boxes 7 are slidably connected to the bottom surface of the workbench 1. The two collection boxes 7 are located below the two through slots 2 respectively. The baffle plate 6 can prevent the fasteners from falling off the surface of the conveyor belt 3 when they fall, which would affect the subsequent inspection and sorting of the fasteners. The two collection boxes 7 are a waste box and a good box, respectively, which can collect the fasteners after inspection and sorting.

[0032] Working principle: When inspecting and sorting fasteners, the first motor 402 is started to drive the eccentric wheel 403 to rotate. When the protruding part of the eccentric wheel 403 rotates to contact the connecting plate 408, it will cause the storage box 407 to move backward and compress the first spring 406. When the protruding part of the eccentric wheel 403 rotates away from the connecting plate 408, the first spring 406 will immediately reset and push the storage box 407 to reset, thereby causing the storage box 407 to vibrate. This vibration can discharge a small number of fasteners inside the storage box 407 to the outside. The discharged fasteners fall from the first guide plate 410 and the second guide plate 411. When the fasteners fall onto the surface of the guide rail 415, the thicker end of the fastener will rest on the guide rail 415. Above 5, the thinner end of the fastener will fall through the gap in the guide rail 415, making the fastener vertical. Then, the second motor 417 is started to drive the first rotating rod 418 to rotate. When the first rotating rod 418 rotates, the conveyor belt 420 will rotate around the first rotating rod 418 and the second rotating rod 419, thereby driving the two moving rods 421 to move. The moving rods 421 push the fastener on the surface of the guide rail 415 to fall into the opening of the guide rail 415, thus realizing the effect of automatic feeding. This greatly improves the efficiency of feeding and avoids the frequent occurrence of image acquisition blind spots or size measurement errors at the detection station caused by problems such as missed or incorrect placement due to operator fatigue or negligence during manual placement, thereby improving the detection accuracy.
