Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, and particularly relates to a thread detection device, a detection system for the processed threads of steel bars, and a main reinforcement processing system for steel cage. Background Art

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

[0003] In addition, since the steel bar is a structural body with a large aspect ratio of length to thickness, when the steel bar is long, it is extremely easy to deform, which undoubtedly increases the detection difficulty of the processed threads on it. Summary of the Utility Model

As Figures 1 to 12As shown in the figure, the thread detection device 100 includes a housing, a carrier table 2, a first pressing unit 3, and an information acquisition unit 4. Among them, the housing includes a first side wall 11 and a second side wall 12.

In this application, by making the thread detection device 100 include the first pressing unit 3 and the carrier table 2 including the first bearing surface 211, the steel bar to be detected can be pressed against the first bearing surface 211 by the first pressing unit 3, so as to position the processed thread on the steel bar, so that the processed thread has better detection conditions, and then improve the accuracy of the detection result of the processed thread.

[0083] It should be noted that the structure of the housing in this application is not specifically limited, and it can be selectively set according to actual needs. In specific implementation, the housing can be selectively made into a square structure or a special-shaped structure. Specifically, as Figures 1 to 3 shown in the thread detection device 100, the housing includes a first side wall 11, a second side wall 12, a third side wall 13, a fourth side wall 14, and a top wall 15.

In specific implementation, the first opening can be selectively a square opening, a circular opening or a special-shaped opening penetrating both sides of the first side wall; the second opening can also be selectively a square opening, a circular opening or a special-shaped opening penetrating both sides of the second side wall.

[0086] In order to be able to observe the actual working condition of the thread detection device 100, a viewing window 16 can be further selectively arranged on at least one of the first side wall 11 and the second side wall 12. Specifically, as Figures 1 to 3 shown in the thread detection device 100, viewing windows 16 are arranged on both the first side wall 11 and the second side wall 12, and the viewing window 16 on the first side wall 11 is located above the first opening 111, and the viewing window 16 on the second side wall 12 is located above the second opening 121.

[0087] In order to make the thread detection device 100 more beautiful and generous, again as Figures 1 to 3 shown, a stepped structure is formed above the side where the third side wall 13 is located, and it has a structure obliquely extending from above the third side wall 13 towards the top wall 15, and a display 17 for displaying detection information and / or detection results is arranged at this structure.

[0088] It should also be noted that the structural form of the "carrying platform" in the present application is not specifically limited, and it can be any structural form that can meet the requirements of carrying and detecting.

In specific implementation, the first bearing surface 211 is a bearing plane, and the first bearing surface 211 is parallel to the passing path of the steel bars to be detected.

[0089] The "first pressing unit" in this application is not specifically limited, and it can be any unit capable of pressing the steel bar to be detected onto the first bearing surface 211. In specific implementation, preferably, the first pressing unit 3 includes a pressing member and a push-pull assembly for driving the pressing member. Under the action of the push-pull assembly, the position of the pressing member can be adjusted to press the steel bar to be detected onto the first bearing surface 211 through the pressing member. In specific implementation, the push-pull assembly can be further selectively an expansion cylinder or a rack and pinion linear module; etc.

[0090] The "information acquisition unit" in this application is also not specifically limited, and it can be a unit capable of acquiring information such as the size and shape of the processed thread, and the acquired information can be processed by inspectors or information processing modules to determine whether the processed thread is qualified. As some preferred implementation manners of this application, the information acquisition unit 4 can be selectively a 2D industrial camera or a 3D industrial camera.

[0091] In specific implementation, the information of the processed thread acquired by the information acquisition unit 4 can be selectively at least part of the major diameter, pitch diameter, minor diameter, pitch, and thread angle of the thread.

[0092] In specific implementation, the thread detection device 100 can be selectively provided with an information processing module, and the information processing module can be selectively an industrial control computer, and the industrial control computer has the function of storing and running a computer program capable of determining whether the processed thread is qualified. As a transformable implementation manner, the information processing module can also be selectively a unit capable of collecting and processing the information acquired by the information acquisition unit 4 and capable of determining whether the processed thread is qualified. In this application, by making the thread detection device 100 include the information acquisition unit 4 and judging whether the steel bar to be detected is qualified through the information acquired by the information acquisition unit 4, the thread detection device 100 better meets the conditions of automated detection, so as to improve the detection efficiency of the thread processed on the steel bar.

[0093] It should also be noted that the number of the information acquisition units 4 included in the thread detection device 100 of this application is not specifically limited. In specific implementation, the number of the information acquisition units 4 can be selectively one, two, three, or more than four. When there are multiple information acquisition units 4, the multiple information acquisition units are arranged circumferentially along the direction in which the steel bar to be detected passes through; in this application, by setting multiple information acquisition units 4, relevant information of the processed thread can be acquired from multiple angles, and the information of the processed thread can be acquired more comprehensively, so that the judgment result of the processed thread is more objective and accurate. Moreover, it is not necessary to rotate the main steel bar to be detected for detection, effectively improving the detection efficiency of the thread detection device.

[0094] In specific implementation, the information acquisition unit 4 can be further electrically connected to the control unit and controlled by the control unit. The information acquisition unit 4 can collect information on the threads of the steel bars to be detected according to the instructions of the control unit. In specific implementation, the control unit can be selectively a relay, a programmable logic controller or a single-chip microcomputer.

By configuring the first pressing unit 3 to 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 of the first push-pull assembly 31, so that the first pressing member 32 has a pressing position and a yielding position. Further, the first pressing unit 3 can press the steel bars to be detected onto the first bearing surface 211 and is also convenient for releasing the steel bars to be detected to meet the transfer requirements of the steel bars to be detected.

[0096] It should be noted that the structure of the first push-pull assembly 31 in the present application is not specifically limited, and it can be any assembly that can press the steel bars to be detected onto the first bearing surface 211 through the first pressing member 32. In specific implementation, specifically as Figures 3 to 8 shown, preferably the first push-pull assembly 31 is a pneumatic telescopic cylinder or a hydraulic telescopic cylinder. As a preference, the first push-pull assembly 31 is a pneumatic telescopic cylinder. The thread detection device 100 includes a first control valve, and the pneumatic telescopic cylinder is connected to the pressure gas source through the first control valve. Further, the first control valve is controlled by the control unit. The control unit can control the first control valve based on the position information of the steel bars to be detected collected by the sensor, so that the first pressing member 32 is in the pressing position or the yielding position. In this way, the automatic pressing process of the steel bars to be detected can be realized.

[0097] As some preferred embodiments of the present application, the first opening 111 may alternatively be the penetration opening for the steel bar to be detected, and in the penetration direction of the steel bar to be detected, the distance between the first bearing portion 21 and the first opening 111 is less than the distance between the information acquisition area of the information acquisition unit 4 and the first opening 111. In specific implementation, the steel bar to be detected can penetrate through the first opening 111, and the penetration end of the steel bar to be detected has a processed thread. When the processed thread is located in the information acquisition area, the information acquisition unit 4 acquires the information of the processed thread on the steel bar to be detected, and further collects and processes the information acquired by the information acquisition unit 4 through the information processing module to further determine whether the processed thread is qualified. In specific implementation, when the information acquisition unit 4 is a 2D industrial camera, the size of the information acquisition area should be larger than the size of the processed thread on the steel bar to be detected.

[0098] In the present application, by making the distance between the first bearing portion 21 and the first opening 111 less than the distance between the information acquisition area of the information acquisition unit 4 and the first opening 111, when the processed thread is located in the information acquisition area, the steel bar body near the processed thread can be pressed against the first bearing portion 21 by the first pressing unit 3, so as to better meet the detection requirements for the processed thread at the end of the steel bar. Specifically, the steel bar to be detected is positioned by the action of the first pressing unit 3 and the first bearing portion 21.

By providing the first pressing portion 322 with the first pressing groove 3221 adapted to the contour of the steel bar to be detected and making the first pressing groove 3221 extend along the passing direction of the steel bar to be detected, the steel bar to be detected can be better pressed on the first bearing surface 211, so as to prevent the steel bar to be detected from slipping, shifting, etc. due to improper force application during the pressing process, and thus make the steel bar to be detected better meet the detection conditions.
