[0003] In the actual production process, it is necessary to process threads on at least one end of the main reinforcement of the steel cage to meet the installation requirements of the steel cage. The detection of the processed threads on the main reinforcement is an extremely important link in the main reinforcement processing process to ensure the normal installation of the steel cage. Since the main reinforcement of the steel cage has a large slenderness ratio and a long size, the main reinforcement is very easy to bend and deform, which greatly increases the difficulty of detecting the processed threads. Therefore, it is very necessary to develop a device that can meet the requirements of processing threads on the main reinforcement of the steel cage. Summary of the invention

[0140] The present application enables the thread detection system to further include a second main rib conveying device 20, and the second main rib conveying device 20 can provide the thread detection device 100 with the main rib to be detected and / or transport the main rib to be detected after being detected by the thread detection device 100. In addition, the present application can also provide a second main rib rotating device 92 on the second main rib conveying device 20, and the main rib can be rotated by the second main rib rotating device 92 to adjust the detection position of the processed thread.

[0141] The present application also provides a steel cage processing system, which includes the thread detection device described in any of the aforementioned embodiments.

[0142] The present application also provides a steel cage processing system, the steel cage processing system comprising a thread detection system as described in any of the above embodiments. Fig.15 As shown, the steel cage processing system also includes a first main bar tapping station 30, a second main bar tapping station 40, a first grinding station 50 and a second grinding station 60. The first main bar tapping station 30 is used to process threads on one end of the main bar, the second main bar tapping station 40 is used to process threads on the other end of the main bar, the first grinding station 50 is used to grind the processed threads on the first end of the main bar, and the second grinding station 60 is used to grind the processed threads on the second end of the main bar.

[0143] In the specific operation, the threads are first processed on both ends of the main reinforcement in sequence through the first main reinforcement tapping station 30 and the second main reinforcement tapping station 40, and then the processed threads on both ends of the main reinforcement are polished in sequence through the first polishing station 50 and the second polishing station 60; after the polishing is completed, the main reinforcement is transferred to the first main reinforcement conveying device 10. Under the action of the first main reinforcement conveying device 10, the first end of the main reinforcement is passed through the first opening 111 into the information collection area of ​​the thread detection device 100, so that the thread detection device 100 first detects the processed threads on the first end of the main reinforcement; when the processed threads on the first end are qualified, the main reinforcement is further transferred to the second main reinforcement conveying device 20, and under the action of the second main reinforcement conveying device 20, the second end of the main reinforcement enters the thread detection device 100 through the second opening 121, and the thread detection device 100 further detects the processed threads on the second end of the main reinforcement.

[0144] The present application also discloses a thread detection method, which is applied to a thread detection device 100 as in some of the aforementioned embodiments, and the thread detection method includes the following processes: making the first stop unit 5 in a state capable of stopping the first end of the main reinforcement to be detected from passing through the thread detection device 100; driving the main reinforcement to be detected to move from the first opening 111 of the thread detection device 100 toward the second opening 121 of the thread detection device 100 to the stop position of the first stop unit 5; making the first clamping unit 3 clamp the main reinforcement to be detected to the first bearing surface 211; collecting information on the processed thread at the first end of the main reinforcement to be detected through the information collection unit 4, and judging whether the processed thread is qualified.

[0145] The detection method is suitable for thread detection of main ribs with a machined thread at one end. In specific implementation, the first stop unit 5 is in a state where it can stop the first end of the main rib to be detected (preferably, the end has a machined thread) from passing through the thread detection device 100, and the first stop member 52 can be driven to a set position by controlling the second push-pull assembly 51. The main rib to be detected is further driven to move toward the first stop unit 5 to the stop position of the first stop member 52. The first push-pull assembly 31 included in the first clamping unit 3 drives the first clamping member 32 to clamp the main rib to be detected onto the first bearing surface 211, thereby positioning the machined thread at the first end, and further collecting relevant information of the machined thread through the information collection unit 4, and processing the collected information collected by the information processing module to determine whether the machined thread is qualified.

[0146] The present application also provides another thread detection method, which is applied to the thread detection device 100 as in some of the aforementioned embodiments, and the thread detection method includes: making the first stop unit 5 in a state capable of stopping the first end of the main reinforcement to be detected from passing through the thread detection device 100; driving the main reinforcement to be detected to move from the first opening 111 of the thread detection device 100 toward the second opening 121 of the thread detection device 100 to the stop position of the first stop unit 5; making the first clamping unit 3 clamp the main reinforcement to be detected to the first bearing surface 211; collecting information of the processed thread at the first end of the main reinforcement to be detected through the information collection unit 4, and judging whether the processed thread is qualified. After determining that the processed thread is qualified, the first clamping unit 3 is in a position to release the main reinforcement to be detected, and the first stop unit 5 is in a yielding position; the main reinforcement to be detected is driven to pass through the thread detection device 100; the second stop unit 7 is in a state capable of stopping the second end of the main reinforcement to be detected from passing through the thread detection device 100; the main reinforcement to be detected is driven to move from the second opening 121 of the thread detection device 100 toward the first opening 111 of the thread detection device to the stop position of the second stop unit 7; the second clamping unit 6 clamps the main reinforcement to be detected to the second bearing surface 221; the information of the processed thread at the second end of the main reinforcement to be detected is collected through the information collection unit 4, and it is determined whether the processed thread is qualified.

[0147] This detection method is suitable for the detection of machined threads in which both ends of the main rib are machined with threads. In specific implementation, the first stop unit 5 is in a state where it can stop the first end of the main rib to be detected from passing through the thread detection device 100, and the first stop member 52 can be driven to a set position by controlling the second push-pull assembly 51. The main rib to be detected is further driven to move toward the first stop unit 5 to the stop position of the first stop member 52. The first push-pull assembly 31 included in the first clamping unit 3 drives the first clamping member 32 to clamp the main rib to be detected onto the first bearing surface 211, thereby positioning the machined thread at the first end, and further collecting relevant information of the machined thread through the information collection unit 4, and processing the collected information collected by the information processing module to determine whether the machined thread at the first end is qualified.

[0148] When the machined thread at the first end of the main rib to be inspected is unqualified, the main rib to be inspected is transferred to the waste storage area. When the machined thread at the first end of the main rib to be inspected is qualified, the machined thread at the second end of the main rib to be inspected is further inspected. In the specific implementation, the main rib to be inspected passes through the thread inspection device 100. Further, the second stop unit 7 is in a state that can stop the second end of the main rib to be inspected from passing through the thread inspection device 100, and the second stop member 72 can be driven to a set position by controlling the fourth push-pull assembly 71. The main rib to be inspected is further driven to move toward the second stop unit 7 to the stop position of the second stop member 72. Further, the second pressing member 62 is driven by the third push-pull assembly 61 included in the second pressing unit 6 to press the main rib to be inspected onto the second bearing surface 221, thereby positioning the machined thread at the second end, and further collecting relevant information of the machined thread through the information collection unit 4, and the collected information collected by the information processing module is processed to determine whether the machined thread at the second end is qualified.

[0149] It should be further pointed out that when the thread detection device has only one information collection unit 4, when detecting the processed thread, it is preferred to rotate the main rib to be detected at least once so that the information collection unit 4 can collect relevant information of the processed thread on the main rib to be detected at different scales; so that the detection result is more objective. When rotating the main rib to be detected, it can be achieved by the first main rib rotating device 91 (or the second main rib rotating device 92). During the rotation process, it is necessary to control the first clamping unit 3 (or the second clamping unit 6) so that the first clamping member 32 (or the second clamping member 62) is in a loose state with the main rib to be detected. After the detection of the main rib to be detected is completed, the first clamping unit 3 (or the second clamping unit 6) is controlled to clamp the main rib to be detected, and the information collection unit 4 collects relevant information of the processed thread again. It should be pointed out that the number of rotations of the main rib to be detected and the number of information collection are not specifically limited, and can be selectively set according to actual needs. In specific implementation, the detected main reinforcement can be selectively rotated once, twice, three times or more than four times; it should be noted that the rotation angle should be specifically set and repeated collection of information on processed threads should be avoided.
