[0002] During the production of steel products, it is often necessary to machine threads on the steel bars to meet the needs of the steel products. Taking steel cages as an example, threads need to be machined on at least one end of the main bars of the steel cage to meet the installation needs of the steel cage. Due to the large amount of steel cages used, mass production of steel cages is the future development direction. Therefore, improving the detection efficiency of the machined threads on the main bars of the steel cage is a technical problem that needs to be solved urgently by those skilled in the art. In the actual production process, it is often necessary to have machined threads on both ends of the steel bars. Therefore, it is urgent to develop a detection device that can meet the needs of detecting steel bars with machined threads on both ends.
[0003] The processing environments of rebar and rebar products are often harsh, which can easily affect inspection equipment. Furthermore, because rebar is a relatively slender structure, it is prone to deformation when it is long, which undoubtedly increases the difficulty of inspecting the threaded parts. Furthermore, during the feeding process into the thread inspection equipment, the rebar will bend under the influence of gravity, further complicating the inspection of the threaded parts.

[0053] In this application, the so-called "passing direction of the inspected steel bar" refers to the direction in which the inspected steel bar passes through the thread detection device during the detection process, that is, the driving direction of the inspected steel bar.
[0054] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0055] The following is based on Figures 1 to 14 The thread detection device 100 provided by the present invention is introduced.
[0056] The present application provides a thread detection device 100, which is used to detect whether the processed threads on the steel bars are qualified. The thread detection device 100 includes a housing, an information collection unit 4, and a steel bar guide assembly 9. Figures 1 to 3 As shown, the housing includes a first side wall 11 and a second side wall 12. The first side wall 11 is provided with a first opening 111, and the second side wall 12 is provided with a second opening 121, and the first opening 111 is opposite to the second opening 121. In the present application, by providing the first opening 111 and the second opening 121 on the thread detection device 100, the steel bar to be detected can enter the thread detection device 100 through one of the first opening 111 and the second opening 121 and pass out through the other of the first opening 111 and the second opening 121. In addition, the steel bar to be detected can pass through the thread detection device 100 in its entirety, so as to meet the requirements of detecting machined threads at any position of the steel bar, and in particular, can realize the detection of steel bars with threads machined at both ends.
[0057] In addition, if Figure 3As shown, the information collection unit 4 is located within the housing and is configured to collect information about the machined threads on the inspected steel bar. The collected machined thread information is used to determine whether the machined threads are qualified. This application enables the thread inspection device 100 to include the information collection unit 4 and to determine whether the inspected steel bar is qualified based on the information collected by the information collection unit 4. This allows the thread inspection device 100 to better meet the conditions for automated inspection, thereby improving the efficiency of inspecting machined threads on steel bars.
[0058] In order to enable the steel bar to be inspected to enter the thread detection device 100 more smoothly, a steel bar guide assembly 9 is further selectively provided at at least one of the first opening 111 and the second opening 121. The steel bar guide assembly 9 has a guide channel 93 connecting the inside and outside of the shell. In a specific implementation, the thread detection device 100 is configured so that the steel bar to be inspected can pass through the thread detection device 100 through the guide channel 93, and the passing path of the steel bar to be inspected passes through the information collection area of the information collection unit 4. By providing the steel bar guide assembly 9, the present application can enable the steel bar to be inspected to enter the thread detection device 100 more smoothly under the action of the steel bar guide assembly 9, which can effectively improve the reliability of the automatic inspection of the steel bar to be inspected, so as to better meet the requirements of automatic inspection.
[0059] In a specific implementation, a steel bar guide assembly 9 (not shown) can be selectively provided at the first opening 111 and the second opening 121, respectively. As a convertible embodiment, a steel bar guide assembly 9 (not shown) can also be provided only at the first opening 111, or only at the second opening 121. Figure 2 and Figure 4 shown).
[0060] In addition, the present application makes the thread detection device 100 include a shell and locates the information acquisition unit 4 inside the shell, so that the processed threads on the inspected steel bars can be inspected in a relatively closed environment, which can effectively reduce the impact of the environment (such as light, smoke, etc.) on the detection results.
[0061] It should be pointed out that the structure of the shell in this application is not specifically limited and can be selectively set according to actual needs. In specific implementation, the shell can be selectively made into a square structure or a special-shaped structure. Figures 1 to 3The thread detection device 100 shown in the figure has a housing including a first sidewall 11, a second sidewall 12, a third sidewall 13, a fourth sidewall 14, and a top wall 15. The first sidewall 11 and the second sidewall 12 are opposite each other, the third sidewall 13 and the fourth sidewall 14 are opposite each other, and the top wall 15 covers the area enclosed by the first, second, third, and fourth sidewalls 11, 12, 13, and 14. A first opening 111 is provided in the middle of the first sidewall 11, and a second opening 121 is provided in the middle of the second sidewall 12. The first opening 111 and the second opening 121 are opposite each other, so that the steel bar being tested can pass through the thread detection device 100 through the first and second openings 111, 121. By configuring the thread detection device 100 to include a housing and locating the information acquisition unit 4 within the housing, the machined threads on the steel bar being tested can be tested in a relatively closed environment, effectively reducing the impact of the environment on the test results.
[0062] 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 should at least meet the requirement that the inspected steel bars can pass through. In a specific implementation, the first opening 111 can be optionally a square opening, a circular opening, or a special-shaped opening that passes through both sides of the first side wall 11; the second opening 121 can also be optionally a square opening, a circular opening, or a special-shaped opening that passes through both sides of the second side wall 12.
[0063] In order to observe the actual working condition of the thread detection device 100, a viewing window 16 may be further selectively provided on at least one of the first side wall 11 and the second side wall 12. Figures 1 to 3 The thread detection device 100 shown is provided with a visual window 16 on both the first side wall 11 and the second side wall 12, and the visual window 16 on the first side wall 11 is located above the first opening 111, and the visual window 16 on the second side wall 12 is located above the second opening 121. In a specific implementation, the visual window 16 provided on the first side wall 11 can be selectively made to be the first visual window, and the visual window 16 provided on the second side wall can be selectively made to be the second visual window. The present application provides a first opening 111 and a second opening 121 on the thread detection device 100, thereby allowing the steel bar to be inspected to enter the thread detection device 100 through one of the first opening 111 and the second opening 121, and to pass out through the other of the first opening 111 and the second opening 121, thereby allowing the steel bar to be inspected to pass through the thread detection device 100 in its entirety, so as to meet the thread detection requirements of steel bars with machined threads at one end or both ends.
[0064] In order to make the thread detection device 100 more beautiful, Figures 1 to 3As shown, a stepped structure is formed above the side where the third side wall 13 is located, and has a structure extending obliquely from the top of the third side wall 13 toward the top wall 15. A display 17 for displaying detection information and / or detection results is provided at this structure. In a specific implementation, the display can be connected to an industrial control computer.
[0065] The "information collection unit" in this application is also not specifically limited. It can be a unit that can collect information such as the size and shape of the processed thread, and the collected information can be processed by an inspector or an information processing module to determine whether the processed thread is qualified. In some preferred embodiments of this application, the information collection unit 4 can be optionally a 2D industrial camera or a 3D industrial camera.

[0067] In a specific implementation, the thread detection device 100 may optionally include an information processing module, which may optionally be an industrial control computer, and the industrial control computer may have the function of storing and running a computer program that can determine whether the processed threads are qualified. As a convertible embodiment, the information processing module may also be selectively a unit that can collect and process the information collected by the information acquisition unit 4 and can determine whether the processed threads are qualified. This application enables the thread detection device 100 to include an information acquisition unit 4, and to determine whether the inspected steel bar is qualified based on the information collected by the information acquisition unit 4, thereby enabling the thread detection device 100 to better meet the conditions for automated detection, thereby improving the detection efficiency of the processed threads on the steel bars.
[0068] It should also be pointed out that the number of information acquisition units 4 included in the thread detection device 100 of the present application is not specifically limited. In specific implementation, the number of 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 4 are arranged circumferentially along the direction in which the inspected steel bar passes. By setting up multiple information acquisition units 4, the present application can collect relevant information about the processed threads from multiple angles, and more comprehensively collect information about the processed threads, so that the judgment results of the processed threads are more objective and accurate. In addition, there is no need to rotate the inspected steel bar before conducting the inspection, which effectively improves the inspection efficiency of the thread detection device 100.
[0069] In a specific implementation, the information collection unit 4 can be further electrically connected to the control unit and controlled by the control unit. The information collection unit 4 can execute information collection on the threads of the inspected steel bar according to the instructions of the control unit. In a specific implementation, the control unit can selectively be a relay, a programmable controller, or a single-chip microcomputer. The control unit can control the information collection unit 4 based on the position information of the inspected steel bar obtained by the sensor.
[0070] As some preferred embodiments of the present application, the steel bar guide assembly 9 can further include an annular enclosure 92, which encloses a guide channel 93, and the guide channel 93 is gradually tapered toward the direction in which the inspected steel bar passes. In the present application, by gradually tapering the guide channel 93 toward the direction in which the inspected steel bar passes, when the ends of the steel bar deflect during transportation, the inspected steel bar can be smoothly guided into the thread detection device 100 under the action of the gradually tapered annular enclosure 92, thereby better improving the requirements for automatic inspection.

The first bearing surface 211 is parallel to the passing direction of the detected steel bar, and the extension area of the guide channel 93 in the passing direction of the detected steel bar is located on the first bearing surface 211. By providing the bearing platform 2, the present application can support the detected steel bar, effectively alleviate the degree of deflection of the end of the detected steel bar, and thus make the processed threads on the detected steel bar better meet the conditions for information collection, further improving the objectivity and accuracy of the detection of the thread detection device 100.
[0073] It should be noted that the base 8 in this application is not specifically limited, and it can be any structure that can meet the installation requirements of the carrier 2, the information collection unit 4, etc. In specific implementation, the base 8 can be selectively made into a frame structure made of profiles (such as Figure 5 As shown), or a box-type structure made of sheet material.
