[0002] During the production of fasteners, the materials usually need to be length-checked. Due to the variety of fastener types, the detection cannot be automated and is often carried out manually.

[0003] The shortcomings and deficiencies of traditional manual operation: 1. Low precision and accuracy: Operating techniques vary from person to person, making it impossible to achieve consistent results; 2. Low efficiency and high cost: Traditional manual operation consumes a lot of human resources and cannot be formalized to ensure high efficiency, resulting in high costs; 3. Data recording and processing issues: Manually recording data onto paper or in Excel is prone to errors and omissions; poor traceability: It is difficult to accurately link each measurement result to a specific time point when recording manually.

[0004] Therefore, it is necessary to design a device for measuring the total length of high-strength fasteners to solve the above problems. Summary of the Invention

Detailed Implementation

[0023] Example: See Figure 1This embodiment describes an automated device for measuring the total length of bolts, mainly comprising a feeding mechanism 1, a transverse feeding mechanism 2, a first longitudinal feeding mechanism 3, a rotating mechanism 4, a transverse pushing mechanism 5, a second longitudinal pushing mechanism 6, and a detection mechanism 7. The feeding mechanism 1 pushes the bolts to the transverse feeding mechanism 2; the transverse feeding mechanism 2 conveys the bolts to the position of the first longitudinal feeding mechanism 3; the first longitudinal feeding mechanism 3 pushes the bolts into the rotating mechanism 4; the rotating mechanism 4 adjusts the bolt's posture to maintain a transverse orientation; the transverse pushing mechanism 5 pushes the bolts to the second longitudinal pushing mechanism 6; the second longitudinal pushing mechanism 6 further pushes the bolts to the detection mechanism 7; the detection mechanism 7 detects the bolt length and automatically sorts qualified and unqualified products. This device, through the coordinated operation of multiple mechanisms, achieves a fully automated process for bolts from feeding, positioning, posture adjustment to detection and sorting, significantly improving detection efficiency and accuracy, and greatly reducing manual intervention.

[0024] Furthermore, the feeding mechanism 1 adopts a pusher-type feeding machine, which has a return ramp 1-1 on one side, and baffles 1-2 are installed obliquely on both sides of the return ramp 1-1. This design can ensure that bolts that are not properly aligned can return to the feeding area along the ramp when they fall, thus ensuring continuous feeding.

[0025] Furthermore, the transverse feeding mechanism 2 is a belt conveyor, with baffles 1-2 on both sides, and its inlet end is connected to the feeding mechanism 1. Through belt conveying in conjunction with the double-sided baffles, the bolts are smoothly transported laterally, effectively preventing deviation or falling, and ensuring the reliability and positioning accuracy of the conveying process.

[0026] Furthermore, the first longitudinal feeding mechanism 3 includes a first support platform and a first pushing cylinder mounted thereon, which is used to accurately push the bolt into the rotating mechanism 4. The cylinder-driven method provides rapid action and precise positioning, which helps to improve the efficiency of inter-process connections.

[0027] Furthermore, the rotating mechanism 4 includes a photoelectric sensor, a rotating support platform 4-1, and a rotary cylinder mounted thereon. A rotary platform is fixed to the rotating end of the rotary cylinder, and a through slot 4-2 for accommodating bolts is provided on the rotary platform. The photoelectric sensor is electrically connected to the rotary cylinder to detect whether the bolt is in a lateral position and provides feedback to control the rotary cylinder to automatically adjust its orientation, ensuring consistent bolt posture and providing an accurate reference for subsequent inspection.

[0028] Furthermore, the transverse pushing mechanism 5 includes a transverse support platform and a transverse pushing cylinder mounted thereon. It has a simple structure and stable thrust, and can quickly and accurately push the bolt to the next work station.

[0029] Furthermore, the second longitudinal pushing mechanism 6 includes a second support platform 6-1 and a second pushing cylinder 6-2 mounted thereon. The cylinder end is provided with a guide plate 6-3 for guiding the bolt to maintain a lateral posture as it enters the second support platform 6-1. The second pushing cylinder 6-2 pushes the lateral bolt into the detection mechanism 7. The guide plate design effectively prevents posture deviation and ensures detection accuracy.

[0030] Furthermore, the detection mechanism 7 includes a material discharge chute 7-1, at which a lifting inclined plate is installed via a lifting cylinder to push the bolt into the material discharge chute 7-1. A detection zone is formed between the lifting inclined plate and the inlet of the material discharge chute 7-1. A detection cylinder 7-2 is located on one side of this zone to press the bolt against the side wall of the material discharge chute. A length measuring camera is arranged above the detection zone for non-contact measurement of the length of the clamped bolt. This structure uses the lifting inclined plate and the detection cylinder to secure the bolt, combined with the camera for high-precision, high-efficiency detection, without mechanical wear.

[0031] Furthermore, the outlet of the discharge chute 7-1 is connected to the qualified product receiving box, and a movable section 7-3 is provided in the middle. This movable section is connected to a non-qualified product pushing cylinder 7-4 and is electrically connected to the length measuring camera. The non-qualified product receiving box is placed below the movable section 7-3. When a bolt length is detected to be unqualified, the non-qualified product pushing cylinder 7-4 pushes the movable section to separate from the main chute, causing the non-qualified product to fall into the corresponding receiving box; if the bolt is qualified, the cylinder does not move, and the qualified product slides along the chute into the qualified product box. This dynamic sorting structure responds quickly and sorts accurately, effectively avoiding material mixing, while the chute design ensures smooth material flow and collection.

[0032] This equipment achieves full automation of the bolt process, from automatic feeding, conveying, positioning adjustment to inspection and sorting, through the coordinated operation of multiple mechanisms including push plate feeding, belt conveying, rotary positioning, cylinder pushing, and visual inspection. Utilizing photoelectric sensors and length measuring cameras for high-precision detection, combined with a dynamically switchable movable section structure, it can quickly complete inspection and sorting, significantly improving operational efficiency and accuracy. The equipment features a modular design, adaptable to the inspection needs of various bolt specifications, and boasts advantages such as precise positioning, stable operation, and convenient maintenance, significantly reducing labor costs and production losses.

[0033] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
