Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and in particular discloses a roller conveying limiting type detection equipment. Background Art

[0002] In modern industrial production, workpiece inspection is a key step in ensuring product quality. However, traditional inspection methods often rely on manual operations, which is not only inefficient but also easily affected by human factors, resulting in inaccurate inspection results and large errors.

[0003] In terms of workpiece transportation, previous conveying equipment can usually only handle workpieces of specific sizes, with poor versatility and difficulty in meeting diverse production needs. When faced with workpieces of different sizes, it is often necessary to replace equipment or make complex adjustments, which not only increases production costs but also affects production efficiency. In addition, existing detection equipment and conveying devices are often complex in structural design, which brings great difficulties to the daily maintenance and operation of the equipment. In summary, in order to solve these problems, there is an urgent need for a new type of detection equipment that can realize automated detection, adapt to workpieces of different sizes, ensure stable transportation, and has a clear structure that is easy to maintain and operate. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a roller conveyor limit detection device.

[0005] To achieve the above-mentioned purpose, the utility model provides a roller conveyor position limiting detection device, comprising a frame, a conveying device and a detection device arranged on the frame, characterized in that: the detection device is arranged above the conveying device, the conveying device has a second conveying mechanism arranged on the frame, an adjustment mechanism and a limiting mechanism for limiting the workpiece from being out of the transport state, the adjustment mechanism is provided with a reciprocating bearing frame, the bearing frame is provided with a first conveying mechanism, the limiting mechanism is provided between the first conveying mechanism and the second conveying mechanism, and the first conveying mechanism and the second conveying mechanism are respectively used to support the two ends of the workpiece away from each other;

[0006] The adjustment mechanism drives the carrier to approach and / or move away from the second conveying mechanism for conveying workpieces of different sizes. The limiting mechanism supports the workpiece to make it out of the transportation state. The driver drives the camera to move above the limiting mechanism to take pictures or images of the workpiece.

[0007] The detection device is installed above the conveying device. The driver drives the camera to photograph the workpiece when it is out of transport. The captured content is transmitted to the controller for inspection and processing. This can realize automated inspection, reduce human errors, and improve the accuracy and efficiency of inspection. The adjustment mechanism can drive the first conveying mechanism to move closer to or away from the second conveying mechanism to meet the conveying needs of workpieces of different sizes, thereby improving the versatility and flexibility of the equipment. The limiting mechanism can effectively support the workpiece to remove it from the transport state, facilitating filming and inspection, ensuring the stability of the workpiece during inspection, and reducing inspection errors caused by shaking. The first conveying mechanism and the second conveying mechanism work together to achieve continuous conveying of workpieces, improving production efficiency.

[0008] Furthermore, the first conveying mechanism has a first motor arranged on the carrier, and a rotating shaft is provided on the output shaft of the first motor, and a roller for transporting the workpiece is provided on one end of the rotating shaft passing through the carrier, and a limiting wheel used in conjunction with the roller and for limiting the workpiece is rotatably provided on the carrier, and a sprocket is provided on the end of the rotating shaft away from the roller; the number of rotating shafts, the number of rollers, the number of limiting wheels and the number of sprockets are set to be multiple, and the direction of the rotating axes of the multiple rollers is cross-set with the direction of the rotating axes of the multiple limiting wheels, the rollers are used to support the bottom of the workpiece, and the limiting wheels are used to block the end of the free end of the workpiece, and a chain is provided between the sprockets on two adjacent rotating shafts.

[0009] The arrangement of multiple rollers and their associated limiting wheels ensures stable clamping and limiting of workpieces, ensuring they do not shift or fall during transport, thereby improving transport reliability and safety. The cross-axis orientation of the rollers and limiting wheels further enhances the workpiece's position limiting and guiding effects, allowing the workpiece to be transported along a predetermined trajectory and reducing deviations and errors during transport. Sprockets are installed on multiple shafts, and adjacent sprockets are connected by chains, enabling the synchronous rotation of multiple shafts and rollers, ensuring smooth and consistent workpiece transport.

[0010] Furthermore, the limiting mechanism has a cylinder arranged on the frame, and a limiting plate is provided on the output shaft of the cylinder; the cylinder drives the limiting plate to support the workpiece out of the transportation state, and the driver drives the camera to move above the limiting plate to photograph the workpiece.

[0011] The pneumatic cylinder provides precise driving force and stroke control, ensuring that the limit plate accurately supports the workpiece out of the transport state, providing stable conditions for filming and inspection. The cylinder stroke and limit plate position can be adjusted according to the shape and size of the workpiece to meet diverse production needs.

[0012] Furthermore, the adjustment mechanism has an adjustment rail arranged on the frame, an adjustment slider is provided on the adjustment rail, the adjustment slider is connected to the carrier frame, an adjustment screw rod is passed through the carrier frame, the adjustment screw rod and the carrier frame are screwed together via a nut, an adjustment motor is provided at one end of the adjustment screw rod close to the carrier frame, and the other end of the adjustment screw rod is rotatably connected to the second conveying mechanism.

[0013] By adjusting the screw and nut, the position of the carrier can be precisely adjusted to accurately accommodate workpieces of varying sizes, improving the equipment's accuracy and reliability. The adjustable guide rails and sliders provide a stable guide for the carrier's movement, ensuring smooth movement and minimizing wobbling and deviation, thereby improving conveying stability and inspection accuracy. The distance between the carrier and the secondary conveyor mechanism can be quickly and easily adjusted to accommodate workpieces of varying sizes and specifications, enhancing the equipment's versatility and flexibility.

[0014] Furthermore, the driver includes a first carrier plate reciprocatingly arranged on the frame, a first driving assembly arranged on the frame to drive the first carrier plate to move, a second carrier plate reciprocatingly arranged on the first carrier plate, a second driving assembly arranged on the first carrier plate to drive the second carrier plate to move, a third carrier plate reciprocatingly arranged on the second carrier plate and a third driving assembly arranged on the second carrier plate to drive the third carrier plate to move; the third carrier plate is connected to the camera.

[0015] The multi-layered carrier plate and independent drive components enable more precise position control, ensuring that the camera can accurately move above the limit mechanism to capture the workpiece, improving inspection accuracy and reliability. This system can adapt to inspecting workpieces of varying shapes, sizes, and positions, achieving optimal capture results through flexible adjustment of the camera's position and angle.

[0016] Furthermore, the third drive assembly has a third drive motor arranged on the second supporting plate, a third screw rod is provided on the output shaft of the third drive motor, a third guide rail is provided on the second supporting plate, the third screw rod and the third supporting plate are screwed together via a nut, and a third slider is provided on the third supporting plate.

[0017] The combination of the third screw and nut enables precise adjustment of the position of the third carrier plate, thereby precisely controlling the position of the camera and meeting the requirements of high-precision testing. The third guide rail and the third slider provide a stable guide for the movement of the third carrier plate, ensuring its smooth and stable movement, reducing jitter and deviation, and helping to improve the clarity of the image and the accuracy of the test. The third drive motor is driven by the third screw, which has high transmission efficiency and can respond quickly to adjust the position of the carrier plate. This structure can withstand large loads and ensure stable operation when carrying components such as the camera.

[0018] Furthermore, the first drive assembly, the second drive assembly and the third drive assembly have the same structure.

[0019] The identical structure reduces the number and specifications of components, lowering design complexity and manufacturing difficulty, thereby improving production efficiency and reducing costs. The identical drive structure ensures consistent motion characteristics for the first, second, and third carrier plates, facilitating motion control and coordination, and improving the operational stability and accuracy of the entire drive.

[0020] Furthermore, the directions of the rotation axes of the multiple rollers are parallel to each other, the directions of the rotation axes of the multiple limiting wheels are parallel to each other, and the directions of the rotation axes of the rollers and the limiting wheels are perpendicular to each other.

[0021] The parallel rollers provide a uniform and stable conveying force, allowing the workpiece to maintain linear motion during transport. The vertically positioned limiting wheels prevent the workpiece from shifting perpendicular to the conveying direction, thereby achieving precise transport. Because the rotational axes of the rollers and limiting wheels are parallel to each other, and the two are arranged perpendicularly, they can effectively limit the position of the workpiece from different directions, ensuring the positional stability of the workpiece during transport. This vertical layout can accommodate a variety of workpiece shapes, whether regular or irregular, and can effectively limit their position, improving the versatility of the equipment.

[0022] Furthermore, the first conveying mechanism and the second conveying mechanism have the same structure.

[0023] A common structure means identical parts can be used for manufacturing and assembly, enabling large-scale production and reducing procurement and production costs. During production, quality inspection and control of conveyor mechanisms with identical structures are more convenient, helping to ensure consistent and stable product quality. This common structure facilitates standardized design and production of conveyor mechanisms, improving the standardization of the entire production system.

[0024] Furthermore, the roller conveyor position limiting detection device also includes a controller, which is electrically connected to the conveying device, the camera and the driver for controlling various parameters in the detection process.

[0025] Centralized control of the conveyor, camera, and driver facilitates unified management and coordination of the entire inspection process, improving the system's integrity and controllability. Various inspection parameters, such as transport speed, camera angle and position, and drive stroke, can be precisely controlled and adjusted to accommodate varying workpieces and inspection requirements. This reduces manual intervention, achieving a high degree of automation in the inspection process and minimizing human error and labor intensity.

[0026] The beneficial effects of the present invention are as follows: the electrical connection between the controller and the transport device, the camera and the driver realizes automated detection, improves detection accuracy and efficiency, and reduces human errors; the adjustable first transmission mechanism, multiple rollers and multiple limit wheels are set to better adapt to workpieces of different sizes, enhance versatility, and ensure stable transportation; the first conveying mechanism and the second conveying mechanism have the same structure, and the first drive assembly, the second drive assembly and the third drive assembly have the same structure, the equipment structure is clear, and it is easy to maintain and operate.

The captured content is transmitted to the controller 4 for detection and processing, which can realize automated detection, reduce human errors, and improve the accuracy and efficiency of detection. The adjustment mechanism 23 can drive the first conveying mechanism 21 to move closer to or away from the second conveying mechanism 22, adapting to the conveying needs of workpieces of different sizes, and improving the versatility and flexibility of the equipment. The limiting mechanism 24 can effectively support the workpiece out of the transport state, facilitating shooting and detection, ensuring the stability of the workpiece during the detection process, and reducing detection errors caused by shaking. The first conveying mechanism 21 and the second conveying mechanism 22 work together to realize continuous conveying of workpieces, thereby improving production efficiency.

[0040] Specifically, the first conveying mechanism 21 has a first motor arranged on a carrier 211, and a rotating shaft 213 is provided on the output shaft of the first motor. A roller 214 for transporting the workpiece is provided on one end of the rotating shaft 213 that passes through the carrier 211, and a limiting wheel 215 that cooperates with the roller 214 and is used to limit the workpiece is rotatably provided on the carrier 211, and a sprocket 216 is provided on the end of the rotating shaft 213 away from the roller 214; the number of rotating shafts 213, the number of rollers 214, the number of limiting wheels 215 and the number of sprockets 216 are set to be multiple, and the rotation axis direction of the multiple rollers 214 is cross-arranged with the rotation axis direction of the multiple limiting wheels 215, the roller 214 is used to support the bottom of the workpiece, and the limiting wheel 215 is used to block the end of the free end of the workpiece, and a chain 217 is provided between the sprockets 216 on two adjacent rotating shafts 213.

[0041] In actual use, the arrangement of multiple rollers 214 and the corresponding limiting wheels 215 can stably clamp and limit the workpiece, ensuring that the workpiece does not shift or fall during transportation, thereby improving the reliability and safety of transportation. The cross-axis arrangement of the rollers 214 and the limiting wheels 215 further enhances the limiting and guiding effect on the workpiece, allowing the workpiece to be transported along a predetermined trajectory and reducing deviations and errors during transportation. Sprockets 216 are provided on each of the multiple rotating shafts 213, and adjacent sprockets 216 are connected by chains 217, achieving synchronous rotation of the multiple rotating shafts 213 and rollers 214, ensuring smooth and consistent workpiece transportation.

[0042] Specifically, the limiting mechanism 24 has a cylinder 241 arranged on the frame 1, and a limiting plate 242 is provided on the output shaft of the cylinder 241; the cylinder 241 drives the limiting plate 242 to support the workpiece out of the transportation state, and the driver 31 drives the camera 32 to move above the limiting plate 242 to photograph the workpiece.

[0043] In actual use, cylinder 241 provides relatively precise driving force and stroke control, ensuring that limit plate 242 accurately supports the workpiece out of its transport state, providing stable conditions for filming and inspection. The stroke of cylinder 241 and the position of limit plate 242 can be adjusted according to the shape and size of the workpiece to meet diverse production needs.

[0044] Specifically, the adjustment mechanism 23 has an adjustment guide rail 234 arranged on the frame 1, and an adjustment slider 24 is provided on the adjustment guide rail 234. The adjustment slider 24 is connected to the carrier frame 211. An adjustment screw rod 232 is passed through the carrier frame 211. The adjustment screw rod 232 is screwed to the carrier frame 211 via a nut. An adjustment motor 231 is provided at one end of the adjustment screw rod 232 close to the carrier frame 211, and the other end of the adjustment screw rod 232 is rotatably connected to the second conveying mechanism 22.

[0045] In actual use, by adjusting the screw rod 232 and the nut, the position of the carrier 211 can be precisely adjusted, thereby accurately adapting to the conveying requirements of workpieces of different sizes and improving the accuracy and reliability of the equipment. The arrangement of the adjustment rail 234 and the adjustment slider 24 provides a stable guide for the movement of the carrier 211, ensuring that the carrier 211 remains stable during movement, reducing shaking and deviation, and helping to improve conveying stability and detection accuracy. The distance between the carrier 211 and the second conveying mechanism 22 can be quickly and conveniently adjusted to accommodate workpieces of different sizes and specifications, enhancing the versatility and flexibility of the equipment.

[0046] Specifically, the driver 31 includes a first carrier plate 312 that is reciprocatingly arranged on the frame 1, a first driving component 311 that is arranged on the frame 1 to drive the first carrier plate 312 to move, a second carrier plate 314 that is reciprocatingly arranged on the first carrier plate 312, a second driving component 313 that is arranged on the first carrier plate 312 to drive the second carrier plate 314 to move, a third carrier plate 316 that is reciprocatingly arranged on the second carrier plate 314, and a third driving component 315 that is arranged on the second carrier plate 314 to drive the third carrier plate 316 to move; the third carrier plate 316 is connected to the camera 32.

[0048] Specifically, the third drive assembly 315 has a third drive motor 3151 arranged on the second supporting plate 314, a third screw rod 3152 is provided on the output shaft of the third drive motor 3151, a third guide rail 3153 is provided on the second supporting plate 314, the third screw rod 3152 is screwed to the third supporting plate 316 via a nut, and a third slider 3154 is provided on the third supporting plate 316.

[0049] In actual use, the cooperation between the third screw rod 3152 and the nut can achieve precise adjustment of the position of the third supporting plate 316, thereby accurately controlling the position of the camera 32 and meeting the requirements of high-precision detection. The setting of the third guide rail 3153 and the third slider 3154 provides a stable guide for the movement of the third supporting plate 316, ensuring that it is stable and smooth during movement, reducing jitter and deviation, and helping to improve the clarity of shooting and the accuracy of detection. The third drive motor 3151 is driven by the third screw rod 3152, with high transmission efficiency, and can respond quickly and realize the position adjustment of the supporting plate. This structure can withstand a large load and ensure that it can still operate stably when carrying components such as the camera 32.

[0050] Specifically, the first driving assembly 311 , the second driving assembly 313 and the third driving assembly 315 have the same structure.

The identical drive structure ensures consistent motion characteristics among the first, second, and third carrier plates 316, facilitating motion control and coordination, and improving the operational stability and accuracy of the entire driver 31.

[0052] Specifically, the rotation axes of the plurality of rollers 214 are parallel to each other, the rotation axes of the plurality of limiting wheels 215 are parallel to each other, and the rotation axes of the rollers 214 and the rotation axes of the limiting wheels 215 are perpendicular to each other.

[0053] In actual use, the parallel rollers 214 provide a uniform and stable conveying force, allowing the workpiece to maintain linear motion during conveyance. The vertically arranged limiting wheels 215 prevent the workpiece from shifting perpendicular to the conveying direction, thereby achieving precise conveying. Because the rotational axes of the rollers 214 and the limiting wheels 215 are parallel to each other, and the two are arranged perpendicularly, they can effectively limit the position of the workpiece from different directions, ensuring the positional stability of the workpiece during conveyance. This vertical layout can accommodate workpieces of various shapes, whether regular or irregular, and can effectively limit their position, improving the versatility of the equipment.

[0054] Specifically, the first conveying mechanism 21 and the second conveying mechanism 22 have the same structure.

[0055] In practice, a common structure allows for the use of identical parts for manufacturing and assembly, enabling large-scale production and reducing procurement and production costs. During production, quality inspection and control of conveyor mechanisms with identical structures are more convenient, helping to ensure consistent and stable product quality. This common structure facilitates standardized design and production of conveyor mechanisms, improving the standardization of the entire production system.

[0056] Specifically, the roller conveyor position limiting detection device further includes a controller 4 , which is electrically connected to the transport device 2 , the camera 32 and the driver 31 for controlling various parameters during the detection process.

[0057] In actual use, centralized control of the conveyor 2, camera 32, and driver 31 is achieved, facilitating unified management and coordination of the entire inspection process and improving the system's integrity and controllability. Various inspection parameters, such as transport speed, camera angle and position, and drive stroke, can be precisely controlled and adjusted to accommodate varying workpieces and inspection requirements. This reduces manual intervention, achieves a high degree of automation in the inspection process, and reduces human error and labor intensity.
