Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and more specifically, to an error-proofing servo correction mechanism based on an industrial smart camera. Background Technology

[0002] In the field of industrial automation precision assembly and machining, achieving high-efficiency and high-precision positioning and orientation of workpieces is a core element in ensuring product quality and production cycle time.

[0003] For a long time, mechanical one-sided, two-pin positioning fixtures have been the standard solution in production sites. This method requires operators to manually align the workpiece visually based on experience before placing it in the fixture for positioning. This not only demands high levels of skill and concentration from the operators but also introduces significant human uncertainty. The inherent limitations of this traditional method have led to several industry pain points: First, the slow pace of manual operation severely restricts the overall efficiency and automation level of the production line. Second, each part with different structural dimensions requires a custom-made positioning fixture, resulting in high costs for fixture design, manufacturing, and management. Furthermore, in flexible manufacturing models with frequent product changes and multiple product types, changeover and machine setup are time-consuming, making it difficult to improve the overall utilization rate of equipment. More importantly, relying on manual labor makes it difficult to guarantee consistent positioning accuracy. Even slight placement deviations or wear on the fixture itself can directly affect the quality stability of subsequent processing or assembly, and may even lead to batch product defects. Although the industry has attempted to make partial improvements to traditional fixtures or introduce semi-automatic auxiliary devices, most have failed to fundamentally overcome the bottleneck of manual intervention or have struggled to balance cost, reliability, and adaptability. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a fault-prevention servo correction mechanism based on an industrial intelligent camera. This device is a fully automatic correction system capable of automatic sensing, intelligent decision-making, and precise execution. It integrates real-time visual inspection and closed-loop motion control functions, thereby achieving rapid changeover and high-precision orientation without unmanned intervention. This fundamentally solves the problems of low work efficiency and high operator skill requirements, improving the overall efficiency of the production line and enhancing the level of automation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An error-proofing servo correction mechanism based on an industrial smart camera includes an industrial smart camera, a programmable logic controller (PLC), a servo driver, a servo motor, and a correction controller. The industrial smart camera, PLC, servo driver, and servo motor are electrically connected in sequence. The correction controller includes a motor mounting plate, a coupling, a rotating shaft, a bearing housing, an angular contact bearing, a column, a positioning plate, and a positioning pin. The servo motor is mounted on the motor mounting plate. The output shaft of the servo motor is connected to the rotating shaft via a coupling. The rotating shaft is supported in the bearing housing by an angular contact bearing. The bearing housing and the motor mounting plate are fixedly connected by multiple columns. The positioning plate is disposed at the end of the rotating shaft and is oriented to the rotating shaft via a positioning pin.

[0006] The coupling is equipped with a flat key inside, which mates with the keyways of the output shaft and the rotating shaft of the servo motor.

[0007] The motor mounting plate is provided with a central stepped hole for mounting the servo motor and multiple threaded connection holes.

[0008] The angular contact bearing is installed in the bearing housing, with its inner ring fitting with the rotating shaft and its outer ring fitting with the bearing housing, to ensure the concentricity of the rotating shaft.

[0009] The column consists of multiple rigid supports of equal height, one end of which is fixedly connected to the bearing seat and the other end of which is fixedly connected to the motor mounting plate, in order to maintain the parallel and centered relationship between the bearing seat and the motor mounting plate.

[0010] The positioning plate is provided with a stepped boss, and the rotating shaft is provided with a stepped hole. The stepped boss of the positioning plate and the stepped hole at the end of the rotating shaft cooperate to achieve concentric positioning, and circumferential fixation is achieved by a positioning pin.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This system uses industrial smart cameras to capture workpiece images in real time and identify angular deviations. Combined with a programmable logic controller (PLC) for intelligent decision-making, it drives a servo system to achieve high-precision correction. The whole system forms a fully automatic closed-loop control system, which greatly reduces the reliance on manual operation and significantly improves the automation level and operating efficiency of the production line.

[0012] In terms of structural design, the device uses angular contact bearings to support the rotating shaft, effectively ensuring concentricity and stability during rotation and avoiding vibration and wear caused by shaft misalignment. The motor mounting plate and bearing housing are connected by multiple rigid columns of equal height, ensuring parallelism and alignment between them, enhancing the overall structural rigidity and precision retention. A keyed connection is installed inside the coupling, reliably transmitting torque and preventing relative rotation, improving the efficiency and reliability of power transmission. The positioning plate achieves concentric and circumferential positioning with the rotating shaft through stepped bosses and positioning pins, further ensuring the repeatability and positioning accuracy of the workpiece clamping.

[0013] This integrated and modular design not only improves the system's response speed and control accuracy, but also enhances the equipment's adaptability to different workpieces, supports rapid changeover and flexible production, and significantly reduces the design and manufacturing costs of special tooling, thus having good economic benefits and promotional value.

The industrial smart camera 1, PLC 2, servo driver 3, and servo motor 4 are electrically connected in sequence. The correction controller 5 includes a motor mounting plate 51, a coupling 52, a rotating shaft 54, a bearing housing 55, an angular contact bearing 56, a column 57, a positioning plate 58, and a positioning pin 59. The servo motor 4 is mounted on the motor mounting plate 51. The output shaft of the servo motor 4 is connected to the rotating shaft 54 ​​via the coupling 52. The rotating shaft 54 ​​is supported in the bearing housing 55 by the angular contact bearing 56. The bearing housing 55 and the motor mounting plate 51 are fixedly connected by multiple columns 57. The positioning plate 58 is located at the end of the rotating shaft 54 ​​and is oriented to the rotating shaft 54 ​​via the positioning pin 59. The intelligent camera 1 is used to identify the workpiece angle deviation. The programmable logic controller (PLC) 2 is used to control the servo driver 3 to drive the servo motor 4 to rotate according to the deviation signal. Then, the workpiece is rotated to the set angle through the correction controller 5. The servo motor 4 is fixed to the motor mounting plate 51 by bolts. Its output shaft is connected to the rotating shaft 54 ​​through the coupling 52 and the internal flat key 53 to reliably transmit torque. The rotating shaft 54 ​​is supported by the angular contact bearing 56 and installed in the bearing seat 55 to ensure rotational concentricity and smooth movement. The bearing seat 55 and the motor mounting plate 51 are connected by multiple columns 57 arranged at the same height to ensure structural rigidity and parallel alignment between the two. The positioning plate 58 is installed at the end of the rotating shaft 54. It achieves radial concentric positioning through the stepped boss and stepped hole, and achieves circumferential fixing through the positioning pin 59. Finally, it is used to directly clamp and drive the workpiece to complete the angle correction.

[0018] Preferably, the coupling 52 is provided with a flat key 53 inside, which cooperates with the keyway of the output shaft of the servo motor 4 and the rotating shaft 54 ​​to ensure the reliability and synchronization of power transmission and avoid loosening or misalignment during the transmission process.

[0019] Preferably, the motor mounting plate 51 is provided with a central stepped hole for mounting the servo motor 4 and multiple threaded connection holes, which facilitates the accurate positioning and secure installation of the servo motor 4 and improves the rigidity and stability of the system.

[0020] Preferably, the angular contact bearing 56 is installed in the bearing housing 55, with its inner ring mating with the rotating shaft 54 ​​and its outer ring mating with the bearing housing 55, in order to ensure the concentricity of the rotating shaft 54 ​​and ensure the smoothness of the correction action.

[0021] Preferably, the column 57 consists of multiple rigid supports of equal height, one end of which is fixedly connected to the bearing seat 55 and the other end of which is fixedly connected to the motor mounting plate 51. This is used to maintain the parallel and centering relationship between the bearing seat 55 and the motor mounting plate 51, thereby enhancing the rigidity of the overall mechanism and extending the service life of the equipment.

[0022] Preferably, the positioning plate 58 is provided with a stepped boss, and the rotating shaft 54 ​​is provided with a stepped hole. The stepped boss of the positioning plate 58 and the stepped hole at the end of the rotating shaft 54 ​​cooperate to achieve concentric positioning, and the positioning pin 59 achieves circumferential fixation. This dual positioning mechanism ensures high repeatability positioning accuracy of workpiece clamping and is suitable for high-precision machining and assembly scenarios.

[0023] First, the system is installed and mechanically adjusted. The servo motor 4 is bolted to the motor mounting plate 51, ensuring a secure installation. Then, the output shaft of the servo motor 4 is connected to the rotating shaft 54 ​​via a coupling 52. During installation, ensure the key 53 mates with the keyway at the shaft end to guarantee reliable power transmission without loosening. The rotating shaft 54 ​​is supported by a pair of angular contact bearings 56 and fixed within the bearing housing 55. During installation, ensure the bearings are properly preloaded and rotate freely. The bearing housing 55 and the motor mounting plate 51 are connected and fixed by multiple columns 57 of equal height. During installation, a dial indicator should be used to check the parallelism and alignment accuracy between them. If necessary, shims can be added for fine-tuning to ensure the overall rigidity and transmission concentricity of the mechanism. Finally, the positioning plate 58 is installed by engaging its stepped boss with the stepped hole at the end of the rotating shaft 54. A positioning pin 59 is inserted to achieve circumferential fixation, completing the mechanical assembly of the correction controller 5.

[0024] For electrical connections, the industrial intelligent camera 1, programmable logic controller (PLC) 2, servo driver 3, and servo motor 4 are connected sequentially via cables, ensuring reliable grounding and good shielding. The PLC 2 is pre-programmed with control procedures, including image recognition signal processing, servo motor motion control algorithms, and system linkage logic, achieving closed-loop control from image recognition to motion execution, characterized by high precision, high response, and automation.

[0025] In actual alignment operations, the industrial intelligent camera 1 acquires real-time images of the workpiece, identifies the deviation between its actual angle and the set angle through a built-in image processing algorithm, and transmits the deviation signal to the programmable logic controller (PLC) 2. The PLC 2 calculates the required angle, direction, and speed of rotation for the servo motor 4 according to a preset program and outputs control signals to the servo driver 3. The servo driver 3 drives the servo motor 4 to rotate, which in turn drives the positioning plate 58 and the workpiece clamped on it to rotate via the rotating shaft 54 ​​until the workpiece reaches the set angle, completing high-precision automatic alignment. The system has automatic calibration and fault diagnosis functions. When using the system for the first time or changing the workpiece model, system calibration can be performed manually to set the camera recognition reference and servo zero point. If out-of-tolerance errors or mechanical jamming are detected during operation, the system can automatically alarm and stop to prevent equipment damage. During maintenance, the lubrication condition of the angular contact bearing 56 should be checked regularly, dirt should be cleaned from the guide rails and positioning pins 59, and all connecting bolts should be tightened to ensure long-term operational accuracy.

[0026] The above description only details the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
