[0019] The following will illustrate the implementation methods of the utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent, and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment. All obvious changes or modifications that belong to the technical concept and utility model content of the utility model are also within the scope of protection of the utility model.

[0020] like Figure 1 As shown, an embodiment of the utility model provides a steel bar offline inspection mechanism, including a steel bar shearing station 1100, an inspection vehicle 1200, a first visual inspection station 1300, a second visual inspection station 1400, a spare visual inspection station 1500 and a robot 1600.

[0021] like Figure 2-4 As shown, the steel bar shearing table 1100 includes four hydraulic shears 1110 and a table body 1120 .

[0022] Four hydraulic shears 1110 are used to cut the welding section from the steel rod and divide the welding section into three sections: front, middle and rear. The middle section contains the weld. For example, a 1100 mm welding section is cut from the steel rod and divided into a 400 mm front section, a 300 mm middle section and a 400 mm rear section.

[0023] The welded section refers to a steel bar section that meets a predetermined length (such as 1100 mm) and contains a weld.

[0024] Four hydraulic shears 1110 are fixed on the table surface of the table body 1120 and are arranged in a front-to-back spacing along the direction in which the traction machine tows the steel rod. The cutting edges of the four hydraulic shears 1110 are all located on the traction path of the steel rod.

[0025] The four lower corners of the platform 1120 are provided with supporting feet 1121, so that a space is formed between the bottom surface of the platform 1120 and the ground for the inspection vehicle 1200 to enter from the left and right directions.

[0026] The platform 1120 is provided with an inclined material discharge channel 1122, and a feed port 1122a of the material discharge channel 1122 is located on the surface of the platform 1120, and the position corresponds to the four hydraulic shears 1310, and a discharge port 1122b is located on the left side of the platform 1120, and the left side has a cover plate 1123 for closing the discharge port, and the upper side of the cover plate 1123 is hinged to the upper edge of the discharge port, and the lower side thereof extends below the bottom surface of the platform 1120, forming a pushing portion 1123a for the inspection vehicle 1200 to push to open the discharge port.

[0027] In this embodiment, the pushing portion 1123a is a vertical plate. Figure 2 .

[0028] like Figure 5 As shown, the inspection vehicle 1200 is an AGV intelligent transport vehicle, which has a material receiving box 1210 on the top. The material receiving box 1210 has three material cavities, which are used to receive the front section 21, the middle section 22 and the rear section 23 of the welding section from the steel bar shearing table 1100 and move them to the docking station. The middle section will be discarded as waste, while the front section and the rear section will be used as samples for size inspection and appearance inspection, respectively.

[0029] After the shearing is completed, the inspection vehicle 1200 moves from right to left under the platform 1120, so that the material receiving box 1210 on it pushes the pushing part 1123a, so that the discharge port 1122b is opened, and the front section, middle section and rear section of the welding section fall into the three material cavities of the material receiving box 1210 respectively. After the inspection vehicle 1200 leaves, the cover plate 1123 closes the discharge port 1122b again under the action of gravity.

[0030] like Figure 1 As shown, the docking station, the first visual inspection station 1300 , the second visual inspection station 1400 and the spare visual inspection station 1500 are all arranged on the horizontal rotation path of the robot arm of the robot 1600 .

[0031] After the inspection vehicle 1200 arrives at the docking station, the robotic arm of the robot 1600 rotates horizontally to the docking station, grabs the front section 21 of the welding section from the inspection vehicle 1200 and places it on the first visual inspection station 1300, and the first visual inspection station 1300 performs size inspection on the steel bar based on the front section 21. At the same time, the robotic arm of the robot 1600 rotates horizontally to the docking station again, grabs the rear section 23 of the welding section from the inspection vehicle 1200 and places it on the second visual inspection station 1400, and the second visual inspection station 1400 performs appearance inspection on the steel bar based on the rear section 23.

[0032] When the first visual inspection station 1300 or the second visual inspection station 1400 fails or the inspection is delayed, the backup visual inspection station 1500 performs size inspection or appearance inspection.

[0033] From the above, it can be seen that an offline inspection mechanism for steel bars provided by an embodiment of the utility model can automatically cut the welding section from the steel bar, and divide the welding section into three sections: front, middle and rear. The front, middle and rear sections are then automatically received by the inspection vehicle and moved to the docking station. Finally, a robot grabs the sample from the inspection vehicle at the docking station and takes it to the visual inspection table for size inspection and appearance inspection, thereby realizing offline inspection, which will not affect the transportation of steel bars on the production line, improves efficiency and reduces labor costs.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
