Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rebar detection technology, specifically relating to an automatic rebar detection feeding line. Background Technology
[0002] Rebar inspection is one of the most demanding parameters in the construction industry. Rebar inspection is often accompanied by hazards such as noise and debris spillage. Therefore, it is necessary to improve inspection efficiency through automation methods to adapt to the increased inspection tasks brought about by increased production capacity.
[0003] Reinforcing bars are mainly cylindrical. Currently, information marking methods such as labeling and inkjet coding are used on their surfaces, but these methods are prone to detachment and identification difficulties. A large number of reinforcing bar samples to be inspected can easily lead to errors or even loss of inspection information. Current reinforcing bar inspection relies entirely on manual feeding, which is not only prone to chaos and errors but also has low efficiency. After the reinforcing bar inspection is completed, the scrap reinforcing bars are usually piled up haphazardly and centrally processed together, making it difficult to find a specific reinforcing bar sample. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic rebar inspection feeding line to solve the technical problem that the surface markings and inkjet codes are easily lost during rebar inspection due to stacking, resulting in inspection difficulties and inaccurate inspection results. The line aims to record information for each rebar sample individually, avoid information loss or identification difficulties during rebar stacking, and improve the inspection efficiency and accuracy of rebar.
[0005] To solve the above-mentioned technical problems, this utility model provides an automatic rebar detection and feeding line, comprising:
[0006] A feeding tray, on which steel bars are placed;
[0007] A scanning sensor is located on one side of the feeding tray and is electrically connected to the feeding tray.
[0008] A robotic arm is located on one side of the feeding tray and is used to grasp steel bars. The robotic arm is electromechanically connected to the scanning sensor.
[0009] Furthermore, the feeding tray is equipped with a sensing chip and a weight sensor. The sensing chip is electrically connected to both the scanning sensor and the weight sensor, and the weight sensor is used to weigh the steel bars.
[0010] Furthermore, it also includes: a moving track, which is circular and electrically connected to the sensing chip.
[0011] Furthermore, multiple feeding trays are provided, each of which is located on the moving track, and each of the multiple feeding trays moves sequentially along the contour of the moving track.
[0012] Furthermore, the robotic arm is located inside the moving track, and the scanning sensor is located outside the moving track.
[0013] Furthermore, each side of the robotic arm is equipped with a testing platform, which is used to test reinforcing bars.
[0014] Furthermore, the detection station is electrically connected to both the sensing chip and the robotic arm.
[0015] The beneficial effects of this utility model are:
[0016] 1. This utility model utilizes a feeding tray with a sensor chip to record information about the rebar samples. Different rebar samples are placed separately on the feeding tray, and a moving track drives the tray to move. A robotic arm then picks up the rebars from the tray and places them onto the testing platform. By recording rebar information through the feeding tray and placing different rebar samples individually, information loss due to rebar stacking is avoided, thus improving the efficiency and accuracy of rebar testing. The sensor chip is linked to the feeding tray, ensuring the uniqueness and traceability of the rebar information.
[0017] 2. This utility model uses a robotic arm and a moving track to move the feeding tray to the scanning sensor. After scanning and sensing by the sensor chip, the scanning sensor sends a signal to the robotic arm, which then grabs the steel bars from the tray onto the detection platform. This automates the steel bar feeding and detection process, eliminating the need for manual handling and avoiding the confusion, errors, and low efficiency associated with manual steel bar feeding. This significantly improves the efficiency of steel bar feeding.
[0018] 3. By setting up a feeding tray, the robotic arm can grab the steel bar back onto the corresponding feeding tray after the testing is completed, which makes it convenient to find the specified steel bar sample later when there is no need to find the steel bar sample after testing.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] Example:
[0027] like Figure 1 and Figure 2 As shown, an automatic rebar inspection and feeding line includes: a feeding tray 1, a moving track 2, a scanning sensor 3, a robotic arm 4, and an inspection table 5. The feeding tray 1 holds the rebar sample to be inspected. The feeding tray 1 moves along the moving track 2 with the rebar sample in its carrying position. The robotic arm 4 picks up the rebar sample from the feeding tray 1 and places it onto the inspection table 5 for inspection. The inspection table 5 then inspects the waste rebar after inspecting the sample. This automated rebar feeding eliminates the need for manual handling, reduces labor costs, and improves the efficiency of rebar inspection.
[0028] After the tray containing the steel bar sample passes through the scanning sensor, the robotic arm grabs the steel bar sample to complete the loading.
[0029] In the diagram, the pallet 1 at the top, labeled 123456...x, contains steel bar samples, while the pallets at the bottom are empty. The robotic arm picks up the samples and places them on the testing platform for inspection. All pallets are loaded at the scanning sensor, and the empty pallets move to the bottom along the track.
[0030] After the rebar inspection is completed, the robotic arm picks up the rebar scrap or the inspected rebar samples and places them into the corresponding numbered tray. When the weight sensor detects a weight approximately equal to the weight of the rebar group, and the number of rebars picked up matches the quantity of the group, the unloading of this group of rebar samples is complete. Subsequently, the tray containing the rebar scrap is removed from the track by manual labor or the AGV robotic arm.
[0031] A sensor chip is installed on the feeding tray 1 to encode and sort the feeding tray and record the detection information of each group of steel bar samples.
[0032] The feeding tray is also equipped with a weight sensor to sense and determine the weight of the steel bar sample, so as to ensure that a set of steel bar samples are on the same feeding tray before and after testing.
[0033] The feeding tray 1 is equipped with an induction chip and a weight sensor. The induction chip is electrically connected to both the scanning sensor 3 and the weight sensor. The operator enters the basic information of the steel bar samples placed on the feeding tray 1 into the induction chip of the feeding tray 1, such as the group number sequence of the steel bar samples, the quantity of steel bars, the number of steel bars placed on the feeding tray 1, and the weight of the steel bar samples. The weight sensor can detect the weight of the steel bars on the feeding tray 1 and send a signal to the induction chip after obtaining the weight of the steel bars. By entering the information of each group of steel bar samples into the induction chip of the feeding tray 1, information loss due to steel bar accumulation is avoided, thus improving the accuracy of steel bar detection.
[0034] In this embodiment, multiple feeding trays 1 are provided, and different steel bar samples are placed on the multiple feeding trays 1. The sensing chip of each feeding tray 1 records the information of the steel bar placed therein. By placing different steel bar samples separately, the information of the steel bar samples is ensured to be clear. The multiple feeding trays 1 are all set on the moving track 2, and the multiple feeding trays 1 move sequentially along the contour of the moving track 2. The moving track 2 is circular and electrically connected to the sensing chip. The moving track 2 can drive the feeding trays 1 to move along the ring.
[0035] In this embodiment, the scanning sensor 3 is located on one side of the feeding tray 1. The scanning sensor 3 is electrically connected to the feeding tray 1. The scanning sensor 3 can send and receive signals with the sensing chip of the feeding tray 1. The moving track 2 moves the feeding tray 1 closer to the scanning sensor 3. The moving track 2 moves for a period of time, stops, and then continues to move. When the moving track 2 moves to the scanning sensor 3, the sensing chip can send a signal to the moving track 2 to stop. The scanning sensor 3 scans the sensing chip of the feeding tray 1 to confirm information and connect signals.
[0036] In this embodiment, the robotic arm 4 is located on the other side of the feeding tray 1. The robotic arm 4 is used to grab the steel bars. The robotic arm 4 is electrically connected to the scanning sensor 3. After the scanning sensor 3 completes the scanning, it sends a signal to the robotic arm 4. Upon receiving the signal, the robotic arm 4 rotates and moves to the scanning sensor 3 to grab the steel bars of the feeding tray 1 that has been scanned by the scanning sensor 3. When the weight sensor detects that the weight of the steel bars on the feeding tray 1 is zero, the moving track 2 continues to move so that the next feeding tray 1 repeats the above operation. The rotation, movement and grabbing of the robotic arm 4 are common knowledge and existing technology in the field. By grabbing the steel bars with the robotic arm 4, the steel bar feeding is automated, reducing labor costs and improving the steel bar feeding efficiency.
[0037] In this embodiment, the robotic arm 4 is located inside the moving track 2, and the scanning sensor 3 is located outside the moving track 2. The detection platform 5 is located on one side of the robotic arm 4 and is used to detect the reinforcing bars. The detection platform 5 is electrically connected to the sensing chip and the robotic arm 4 respectively. After the robotic arm 4 grabs the reinforcing bars on the feeding tray 1, it moves the reinforcing bars to the detection platform 5. The detection platform 5 detects the reinforcing bars and sends a signal to the robotic arm 4 after detection. The robotic arm 4 grabs the reinforcing bars and puts them back on the original feeding tray 1. When the weight sensor senses that the weight of the reinforcing bars on the feeding tray 1 is the original weight, the signal is released.
[0038] In summary, different steel bar samples are placed on different feeding trays 1, and the information of the steel bar samples is recorded into the sensing chip of the feeding tray 1. Under the action of the sensing chip, the moving track 2 moves the feeding tray 1 closer to the scanning sensor 3. After scanning the sensing chip, the scanning sensor 3 sends a signal to the robotic arm 4. The robotic arm 4 moves to the scanning sensor 3 to grab the steel bar and picks it up. The steel bar is then picked up and placed on the detection table 5 for detection. After the detection is completed, under the action of the detection table 5 and the sensing chip, the robotic arm 4 picks up the steel bar and places it back on the original feeding tray 1.
