Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to a steel bar rotating device, thread detection equipment and a thread detection system. Background Art

[0002] In the production process of steel products, it is often necessary to process threads on the steel bars to meet the use requirements of the steel products. Taking the steel cage as an example, it is necessary to process threads on at least one end of the main bars of the steel cage to meet the installation requirements of the steel cage. Since the use of steel cages is large, realizing mass production of steel cages is the future development direction. Therefore, improving the detection efficiency of the processed threads on the main bars of the steel cage is a technical problem that needs to be solved urgently by technical personnel in this field. In the actual production process, it is often necessary to have processed threads on both ends of the steel bars. Therefore, it is urgent to develop a detection device that can realize the detection needs of steel bars with processed threads on both ends.

[0003] In the actual production process, since the information collection unit can only collect information from one side of the processed thread, the collected information of the processed thread is incomplete, which in turn affects the reliability of the processing thread detection results of the inspected steel bars. If the inspected steel bars can be rotated, the processing thread information can be collected more comprehensively, which can effectively improve the reliability of the detection results.

[0004] In addition, since the steel bar is a slender structure with a large length-to-slenderness ratio, it is very easy to deform when the steel bar is long, which undoubtedly increases the difficulty of detecting the processed threads at its ends. Utility Model Content

[0054] According to the following Figures 1 to 8 The utility model provides a steel bar rotating device 1, a thread detection device 10 and a thread detection system.

[0055] The steel bar rotating device 1 provided in the present application is used for detecting a thread detection device 10 or a thread detection system for detecting the processed threads on the steel bar, such as Figure 1 As shown, the steel bar rotating device 1 includes a hollow rotating platform 11, a driving motor 12 and a steel bar locking and releasing unit 13. Among them, the hollow rotating platform 11 includes a platform power input end and a platform power output end.

The steel bar locking and releasing unit 13 is fixedly connected to the platform power output end, and the steel bar locking and releasing unit 13 is configured to lock and release the detected steel bar passed through the hollow rotating platform 11.

[0056] The steel bar rotating device 1 of the present application can rotate the steel bar to better meet the rotation requirements during the processing thread detection of the steel bar to be detected by the thread detection device 10 or the thread detection system. In addition, by making the steel bar rotating device 1 include a hollow rotating platform 11, a driving motor 12 and a steel bar locking and releasing unit 13, the conditions for automatic operation of the steel bar rotation can be met.

[0057] In specific implementation, the size and model of the hollow rotating platform 11 in the present application are not specifically limited, and are selectively set according to actual needs (such as the diameter of the steel bar to be rotated, the rotation accuracy requirements, the rotation speed, etc.).

[0058] It should be noted that the steel bar locking and releasing unit 13 in the present application is not specifically limited, and it can be any unit that can meet the locking and releasing of the steel bar to be detected. In specific implementation, the steel bar locking and releasing unit 13 can be selectively set as a pneumatic gripper or a hydraulic gripper, and further make the steel bar locking and releasing unit 13 be controlled by a control unit. As an alternative implementation, the steel bar locking and releasing unit 13 can also be selectively set as an electromagnetic gripper, and further make the electromagnetic gripper be electrically connected to the control unit and be controlled by the control unit.

During specific operation, the clamping state or the releasing state of the pneumatic gripper is realized according to the set working conditions; when the steel bar to be detected needs to be rotated, make the pneumatic gripper in the clamping state, and drive the pneumatic gripper to rotate a set angle through the driving motor 12 via the hollow rotating platform 11, and release the steel bar to be detected after rotating the set angle. When the steel bar locking and releasing unit 13 is a hydraulic gripper, further connect the hydraulic gripper to the hydraulic source through an electromagnetic directional valve and a hydraulic pump, and make the electromagnetic directional valve be electrically connected to the control unit and be controlled by the control unit; during specific operation, the clamping state or the releasing state of the hydraulic gripper is realized according to the set working conditions; when the steel bar to be detected needs to be rotated, make the hydraulic gripper in the clamping state, and drive the hydraulic gripper to rotate through the driving motor 12 via the hollow rotating platform 11.

[0060] In specific implementation, the rotation speed and rotation angle of the hollow rotating platform 11 driving the steel bar locking and releasing unit 13 are not specifically limited, and can be selectively set according to actual needs.

[0061] As some preferred embodiments of the present application, the drive motor 12 can be further selectively a servo motor, and the servo motor is further electrically connected to the control unit and controlled by the control unit. In specific implementation, the servo motor cooperates with the hollow rotary platform 11, which can effectively improve the working accuracy of the steel bar rotating device 1 to better meet the rotation requirements during the processing thread detection.

The information processing unit is configured to collect and process the information collected by the information acquisition unit 4 and determine whether the processed thread is qualified.

[0063] By making the thread detection device 10 of the present application include the information acquisition unit 4 and the information processing unit, the information processing unit of the thread detection device 10 can collect and process the information collected by the information acquisition unit 4, and further determine whether the steel bar to be detected is qualified. Preferably, the automatic detection process of the processed thread can be realized through the control of the control unit. In addition, by making the thread detection device 10 of the present application include the steel bar rotating device 1, under the rotation action of the steel bar rotating device 1, the information on the processed thread of the steel bar to be detected can be collected more comprehensively, thereby improving the objectivity and reliability of the detection result.

In specific implementation, the thread detection device 10 is configured such that the end of the steel bar to be detected can pass through the hollow rotary platform 11 from the first side or the second side of the information acquisition area into the information acquisition area of the information acquisition unit 4.

[0065] As some preferred embodiments under the foregoing embodiments, it is further preferably that the rotation center line of the hollow rotary platform 11 coincides or substantially coincides with the passing direction of the steel bar to be detected. By making the rotation center line of the hollow rotary platform 11 coincide or substantially coincide with the passing direction of the steel bar to be detected, the application can further reduce the movement range of the steel bar to be detected during rotation, reduce the dynamic load generated by the steel bar to be detected during rotation, so as to avoid the steel bar to be detected from falling off, shifting, etc. during rotation, and further ensure the rotation accuracy of the steel bar to be detected.

[0067] In specific implementation, it can be selectively made that the first end of the steel bar to be detected passes through the hollow rotary platform on the first side of the information collection unit 4 and enters the information collection area of the information collection unit 4. Then the information collection unit 4 collects the information of the processing thread at the first end. During the process of the information collection unit 4 collecting information, the steel bar to be detected is rotated at least once by the steel bar rotation device 1 to obtain more comprehensive information of the processing thread. The information processing unit collects and processes the information collected by the information collection unit, and further determines whether the steel bar to be detected is qualified based on the collected information.

[0068] When the processing thread at the first end is qualified, it is further made that the steel bar to be detected passes from the first side of the information collection area to the second side of the information collection area, and further made that the second end of the steel bar to be detected enters the information collection area from the second side of the information collection unit 4. Then the information collection unit 4 collects the information of the processing thread at the second end. During the process of the information collection unit 4 collecting information, the steel bar to be detected is rotated at least once by the steel bar rotation device 1 to obtain more comprehensive information of the processing thread.

[0069] As some transformable embodiments of the present application, when only one end of the steel bar to be detected is provided with a processed thread, one side of the first side and the second side of the information collection area of the information collection unit 4 can also be selectively provided with the steel bar rotation device 1.

Among them, the thread detection device 10 includes an information collection unit 4, and the information collection unit 4 is configured to collect information on the processed thread on the steel bar to be detected. The information collected by the information collection unit 4 is used to determine whether the processed thread is qualified. As Figure 2 or Figure 3 shown, the first steel bar transfer device 20 included in the thread detection system is provided on the first side of the thread detection device 10. The first steel bar transfer device 20 is configured to transfer the steel bar to be detected from the first side of the thread detection device 10 to the thread detection device 10, so that the processed thread on the steel bar to be detected is located in the information collection area of the information collection unit 4. A steel bar rotation device 1 is provided on the transfer route of the steel bar to be detected on the first side of the thread detection device 10.

[0071] It should be noted that the thread detection device included in the thread detection system of the present application is not specifically limited, and it can be any device that meets the thread detection requirements, specifically such as Figure 4 and Figure 5 discloses a thread detection device. As a transformable embodiment, in specific implementation, Figure 4 and Figure 5 the thread detection device disclosed may not be provided with a housing.

[0072] It should be noted that the first steel bar transfer device in the present application is not specifically limited, and it can be any transfer device that can transfer the steel bar to be detected. In specific implementation, the first steel bar transfer device 20 is configured to transfer the steel bar to be detected along the length direction of the steel bar to be detected towards the thread detection device 10.

[0073] In this application, by arranging the first steel bar transfer device 20 on the first side of the thread detection device 10, the processed threads on the steel bar to be detected can be fed into the information collection area of the information collection unit 4 from the first side of the thread detection device 10. Further, by controlling the first steel bar transfer device 20 and the information collection unit 4 by the control unit, an automated detection process for the steel bar to be detected can be achieved. In addition, by arranging the steel bar rotation device 1 in this application, the steel bar to be detected can be rotated.

[0075] It should be noted that there are no specific restrictions on the "information collection unit" included in the thread detection device 10 involved in this application. It can be a unit capable of collecting information such as the size and shape of the processed threads, and the collected information can be processed by inspectors or the information processing unit to judge whether the processed threads are qualified. As some preferred implementation modes of this application, the information collection unit 4 can be selectively a 2D industrial camera or a 3D industrial camera. In specific implementation, the information collected by the information collection unit 4 about the processed threads can selectively include at least part of the major diameter, pitch diameter, minor diameter, pitch, and thread profile angle of the threads. Preferably, the collected information includes at least the pitch diameter and pitch.

[0076] In specific implementation, when the information collection unit 4 is a 2D industrial camera, static information collection needs to be performed on the processed threads during the detection process of the processed threads, that is, when the information collection unit 4 is in the information collection process, the steel bar to be detected is in a static state. When the information collection unit 4 is a 3D industrial camera, static detection or dynamic detection can be performed on the processed threads during the detection process of the processed threads, that is, when the information collection unit is in the information collection process, the steel bar to be detected is in a static state or a moving state.

[0077] The information processing unit involved in this application can optionally be an industrial control computer, and the industrial control computer has the function of storing and running a computer program capable of judging whether the processed thread is qualified. As an alternative implementation, the information processing unit can also optionally be a unit capable of collecting and processing the information collected by the information collection unit 4 and capable of judging whether the processed thread is qualified. In this application, by making the thread detection device 10 include the information collection unit 4 and judging whether the tested steel bar is qualified based on the information collected by the information collection unit 4, the thread detection device 10 can better meet the conditions of automated detection, so as to improve the detection efficiency of the threads processed on the steel bars.

[0078] When the thread detection system involved in some of the foregoing embodiments of this application is working specifically, the tested steel bar is transported towards the thread detection device 10 by the first steel bar transfer device 20. One end of the tested steel bar with the processed thread is passed through the hollow rotating platform 11 of the steel bar rotating device 1 and transported to the information collection area of the thread detection device 10, and then the tested steel bar is made to be in a stationary state. Further, the information collection unit 4 collects the information of the processed thread on the tested steel bar. During the process of the information collection unit 4 collecting information, according to the process requirements, the tested steel bar is rotated at least once by controlling the steel bar rotating device 1, and after each rotation of the tested steel bar, the information collection unit 4 collects the relevant information of the processed thread. The information processing unit collects and processes the information collected by the information collection unit 4 and judges whether the tested steel bar is qualified.

[0079] As some preferred embodiments of this application, such as Figure 3 shown, on the basis of the thread detection system involved in the foregoing some embodiments, the thread detection system can further optionally include a second steel bar transfer device 30. And the second steel bar transfer device 30 is arranged on the second side of the thread detection device 10, and the second steel bar transfer device 30 is configured to be able to transfer the tested steel bar from the second side of the thread detection device 10 to the thread detection device 10. Further, a steel bar rotating device 1 is provided on the transfer route of the tested steel bar on the second side of the thread detection device 10. In specific implementation, the thread detection device 10 is further configured such that the tested steel bar can pass through from the first side of the thread detection device 10 to the second side along its length direction, or the tested steel bar can pass through from the second side of the thread detection device 10 to the first side along its length direction.

[0080] In this application, by including a first steel bar transfer device 20 and a second steel bar transfer device 30 in the thread detection system, the steel bar to be detected can be passed from one side of the thread detection device 10 to the other side, enabling the thread detection device 10 to detect the processed threads at at least one end of the steel bar to be detected. Further, by controlling both the first steel bar transfer device 20 and the second steel bar transfer device 30 by a control unit, an automated transfer process of the steel bar to be detected can be achieved. Additionally, in this application, by providing a steel bar rotation device 1, the steel bar to be detected can be rotated, and thus, according to the information collection requirements, the steel bar to be detected can be rotated to collect more comprehensive information on the processed threads.

[0081] When the thread detection system including the first steel bar transfer device 20 and the second steel bar transfer device 30 is working, and both ends of the steel bar to be detected have processed threads, the first steel bar transfer device 20 can selectively transport the steel bar to be detected towards the thread detection device 10. The first end of the steel bar to be detected is passed through the hollow rotating platform 11 of the steel bar rotation device 1 on the first side of the thread detection device 10 and transported to the information collection area of the thread detection device 10. Then, the steel bar to be detected is kept stationary, and the information collection unit 4 collects the information on the processed threads at the first end of the steel bar to be detected. During the process of the information collection unit 4 collecting information, according to the process requirements, the steel bar to be detected is rotated at least once by controlling the steel bar rotation device 1, and after each rotation of the steel bar to be detected, the information collection unit 4 collects the relevant information on the processed threads. The information processing unit collects and processes the information collected by the information collection unit 4 and determines whether the steel bar to be detected is qualified.

[0082] When the processed threads at the first end are qualified, the steel bar to be detected is passed through the information collection area of the thread detection device 10 by the first steel bar transfer device 20 and the second steel bar transfer device 30. During the process of the steel bar to be detected passing through the thread detection device 10, the steel bar to be detected passes through the hollow rotating platform 11 included in the steel bar rotation device 1 on the second side of the thread detection device 10. Further, the second steel bar transfer device 30 transports the second end of the steel bar to be detected to the information collection area and keeps the steel bar to be detected stationary. Further, the information collection unit 4 collects the information on the processed threads on the steel bar to be detected. During the process of the information collection unit 4 collecting information, according to the process requirements, the steel bar to be detected is rotated at least once by controlling the steel bar rotation device 1, and after each rotation of the steel bar to be detected, the information collection unit 4 collects the relevant information on the processed threads. The information processing unit collects and processes the information collected by the information collection unit 4 and determines whether the steel bar to be detected is qualified. Thus, the detection of the steel bar to be detected is completed.

[0083] It should be noted that during the information collection process, the number of times and the angle of rotation of the steel bar to be detected are not specifically limited and can be selectively set according to actual needs. During specific implementation, the number of times the steel bar to be detected rotates can be selectively one, two, three, or more than four times, and the angle of rotation each time should be set to avoid duplicate information collection.

[0084] As some preferred embodiments under the foregoing implementation manners, during specific implementation, the thread detection device 10 includes a steel bar transfer device. When specifically setting it, the transfer route of the steel bar to be detected should be made to coincide or substantially coincide with the rotation center line of the hollow rotating platform 11 as much as possible.

By making the first pressing unit 3 include the first push-pull assembly 31 and the first pressing member 32, and fixedly connecting the first pressing member 32 to the push-pull end of the first push-pull assembly 31, the position of the first pressing member 32 can be adjusted during the push-pull process by the first push-pull assembly 31, so that the first pressing member 32 has a pressing position and a yielding position; thus enabling the first pressing unit 3 to press the steel bar to be detected onto the first bearing surface 211 and facilitating the release of the steel bar to be detected, thereby meeting the transfer requirements of the steel bar to be detected.

[0090] It should be noted that the structure of the first push-pull assembly 31 in this application is not specifically limited, and it can be any assembly capable of pressing the steel bar to be detected onto the first bearing surface 211 through the first pressing member 32.
