Taking a steel reinforcement cage as an example, it is necessary to process threads at least at one end of the main reinforcement of the steel reinforcement cage to meet the installation requirements of the steel reinforcement cage. Since the usage amount of steel reinforcement cages is large, realizing the batch production of steel reinforcement cages is the future development direction. Therefore, improving the detection efficiency of the processed threads on the main reinforcement of the steel reinforcement cage 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.

[0064] In this application, the so-called "penetration direction of the steel bar to be detected" refers to the direction in which the steel bar to be detected penetrates the thread detection device during the detection process, that is, the driving direction of the steel bar to be detected.

[0065] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0066] Next, according to Figures 1 to 15 The thread detection device 100 provided by the present utility model will be introduced. The thread detection device 100 is used to detect whether the processed thread on the steel bar is qualified. The thread detection device 100 includes a carrier table 2, a first pressing unit 3, and an information acquisition unit 4. Among them, the carrier table 2 has a first carrying part 21, and the first carrying part 21 has a first carrying surface 211; the first pressing unit 3 faces the first carrying surface 211, and the first pressing unit 3 is configured to be able to press the steel bar to be detected against the first carrying surface 211. The information acquisition unit 4 is configured to acquire information about the processed thread, and the acquired information is used to determine whether the processed thread is qualified.

[0067] In specific implementation, the thread detection device 100 is configured such that the steel bar to be detected can pass through from the first side of the thread detection device 100 to the second side of the thread detection device 100, and the passing path of the steel bar to be detected passes through the information acquisition area of the information acquisition unit 4. Preferably, the first pressing unit 3 has a pressing position and a yielding position. When the first pressing unit 3 is in the pressing position, the first pressing unit 3 can press the steel bar to be detected against the first carrying surface 211; when the first pressing unit 3 is in the yielding position, the steel bar to be detected can pass through the area between the first pressing unit 3 and the carrier table 2 from the first side of the thread detection device 100. In this application, by enabling the steel bar to be detected to pass through from the first side of the thread detection device 100 to the second side of the thread detection device 100, the steel bar to be detected can be made to pass through the thread detection device 100 entirely, so as to meet the detection of the processed thread at any position of the steel bar, and in particular, the detection of a steel bar with threads processed at both ends can be realized.

[0068] The structural form of the "carrier table" in this application is not specifically limited, and it can be any structural form that meets the carrying requirements and detection requirements. Specifically, such as Figures 3 to 5 and Figure 9The shown load-bearing platform 2 includes a bent part formed by bending a metal plate, and a reinforcing rib is provided at the bent part of the bent part. As an alternative implementation, the load-bearing platform 2 can also be selectively a box-shaped structure formed by welding plates, or a block-shaped structure cast from metal. In specific implementation, the first bearing surface 211 is made as a bearing plane, and the first bearing surface 211 is parallel to the passing path of the steel bar to be detected. In specific implementation, as Figures 3 to 5 shown, the load-bearing platform 2 is installed on the base 8, and a plurality of height-adjustable feet are connected below the base 8. The height of the first bearing surface 211 can be adjusted by the feet, so that the passing path of the steel bar to be detected is tangent to the first bearing surface 211 or the distance between the passing path of the steel bar to be detected and the first bearing surface 211 is extremely small; further, when the first pressing unit 3 presses the steel bar to be detected onto the first bearing surface 211, the steel bar to be detected will not have a large amount of deformation, so as to better meet the detection conditions for processing threads.

[0069] There is no specific limitation on the "first pressing unit" in this application, and it can be any unit that can press the steel bar to be detected onto the first bearing surface 211. In specific implementation, the first pressing unit 3 should also have a pressing position and a yielding position. 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, so that the pressing member has a pressing position for pressing the steel bar to be detected onto the first bearing surface 211, and also has a yielding position for making the pressing member allow the steel bar to pass through the thread detection device 100. In specific implementation, the push-pull assembly can be further selectively an expansion cylinder (pneumatic expansion cylinder, hydraulic expansion cylinder) or a rack and pinion linear module; etc. By making the thread detection device 100 include the first pressing unit 3 and the load-bearing platform 2 including the first bearing surface 211, this application can press the steel bar to be detected onto the first bearing surface 211 through 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 further improve the accuracy of the detection result of the processed thread.

[0070] There are no specific restrictions on the "information acquisition unit" in this application. It can be a unit capable of acquiring and processing relevant information 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 embodiments of this application, the information acquisition unit 4 can be selectively a 2D industrial camera or a 3D industrial camera. During specific implementation, the information of the processed thread acquired by the information acquisition unit 4 can selectively include at least part of the major diameter of the thread, the pitch diameter of the thread, the minor diameter of the thread, the pitch, and the thread profile angle. Preferably, the acquired information includes at least the pitch diameter and the pitch of the thread. By including the information acquisition unit 4 in the thread detection device 100 and judging whether the tested steel bar is qualified based on the information acquired by the information acquisition unit 4, this application enables the thread detection device 100 to better meet the conditions of automated detection, thereby improving the detection efficiency of the threads processed on the steel bar.

[0071] 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 restricted. During specific implementation, the number of the information acquisition units 4 can be selectively one, two, three, or more than four. When there are at least two information acquisition units 4, the multiple information acquisition units 4 are arranged circumferentially along the direction in which the tested steel bar passes through; by setting multiple information acquisition units 4, this application can acquire relevant information of the processed thread from multiple angles, more comprehensively acquire the information of the processed thread, so that the judgment result of the processed thread is more objective and accurate. Moreover, it is not necessary to rotate the tested main reinforcement for detection, effectively improving the detection efficiency of the thread detection device 100.

[0072] During specific implementation, the thread detection device 100 can be further configured to include a control unit. The information acquisition unit 4 is electrically connected to the control unit and is controlled by the control unit. The information acquisition unit 4 can execute information acquisition on the threads on the tested steel bar according to the instructions of the control unit. During specific implementation, the control unit can be selectively a relay, a programmable logic controller, or a single-chip microcomputer. The control unit can control the information acquisition unit 4 based on the position information of the tested steel bar detected by the sensor. Additionally, the first pressing unit 3 can also be controlled by the control unit.

[0073] In specific implementation, the thread detection device 100 can optionally include an information processing module. The information processing module 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 a variant implementation, the information processing module can also optionally be a unit capable of collecting and processing the information collected by the information acquisition unit 4 and capable of judging 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 tested steel bar is qualified based on the information collected by the information acquisition unit 4, the thread detection device 100 can better meet the conditions of automatic detection, so as to improve the detection efficiency of the threads processed on the steel bar.

[0074] As some preferred implementation manners of this application, the thread detection device 100 can also optionally include a housing, and a first opening 111 and a second opening 121 for the tested steel bar to pass through are provided on the housing, and the first opening 111 and the second opening 121 are located on the passing path of the tested steel bar.

[0075] 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 optionally be integrally square or of 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. Among them, the first side wall 11 and the second side wall 12 are opposite, the third side wall 13 and the fourth side wall 14 are opposite, and the top wall 15 covers the area surrounded by the first side wall 11, the second side wall 12, the third side wall 13 and the fourth side wall 14. And the first opening 111 is provided in the middle of the first side wall 11, the second opening 121 is provided in the middle of the second side wall 12, and the first opening 111 is opposite to the second opening 121, so that the tested steel bar can pass through the thread detection device 100 through the first opening 111 and the second opening 121. In this application, by making the thread detection device 100 include a housing and making the information acquisition unit 4 located inside the housing, the processed threads on the tested steel bar are detected in a relatively enclosed environment, which can effectively reduce the influence of the environment on the detection result; in addition, effects such as dust prevention can also be achieved.

[0076] It should be noted that the shapes and sizes of the first opening 111 and the second opening 121 in this application are not specifically limited, but at least should meet the requirement that the tested steel bar can pass through. In specific implementation, the first opening 111 can optionally be a square opening, a circular opening or a special-shaped opening penetrating both sides of the first side wall 11; the second opening 121 can also optionally be a square opening, a circular opening or a special-shaped opening penetrating both sides of the second side wall 12.
