[0018] Please see Figure 1 and Figure 2 As shown, this embodiment provides a flux-cored wire joint detection device, including: The welding wire feeding machine 1 has a rotating shaft with a spool 2 on it. The spool 2 is wound with flux-cored welding wire (not shown in the attached figure). The spool 2 is also equipped with a piece of paper 3 for marking the welding wire joint.

[0019] Specifically, in this embodiment, before the finished welding wire is wound onto the I-beam 2, paper 3 needs to be placed on it, and the welding wire joint is placed on the paper 3 accordingly. When preparing for inspection, the vision inspection device 6, the adjusting bracket 5, and the fixed base 4 are assembled. The fixed base 4 is installed on the welding wire feeding machine 1 with fastening bolts. The position of the adjusting bracket 5 is adjusted to the optimal inspection angle. When the welding wire take-up machine is used to take up the wire, the vision inspection device 6 is started for inspection. At the same time, in order to avoid the welding wire joint end breaking and causing spatter, a protective net 8 is installed between the welding wire feeding machine 1 and the welding wire take-up machine to ensure the safety of the operator.

[0020] The flux-cored wire joint detection device described in this embodiment has a simple structure, is easy to assemble and use, and has convenient maintainability and good operational stability. By using this device, the stability of the production process is effectively guaranteed, and safety risks caused by improper joint handling are avoided, thereby creating a safe production environment, improving workshop production efficiency, and promoting the automation and intelligence of the flux-cored wire production process.

[0021] In some embodiments, the paper 3 is attached to the outer surface of the I-beam 2, and the welding wire joint is correspondingly disposed at the paper 3 and wound around the I-beam 2.

[0022] Specifically, in this embodiment, a connector marking paper 3 with a size of 150mm*100mm is used. The paper 3 is placed on the outer surface of the I-beam 2, and the welding wire connector is set at the corresponding position on the paper 3. The paper 3 is pressed firmly onto the I-beam 2 by the layered flux-cored welding wire.

[0023] In some embodiments, the fixed base 4 is disposed at the edge of the wire feeding end of the wire feeding machine 1. The fixed base 4 includes a base plate 41, a support plate 42 and a fixed plate 43. The base plate 41 is disposed on the wire feeding machine 1, and the fixed plate 43 is supported on the base plate 41 by the support plates 42 disposed on both sides. Both the support plate 42 and the fixing plate 43 are C-shaped structural plates, and the bottom plate 41 is a horizontal straight plate.

[0024] Specifically, in this embodiment, such as Figure 2 and 3As shown, the fixed base 4 (its dimensions are: 1200mm in length, 330mm in width, and no more than 300mm in height) is detachably mounted on the wire feeding machine 1. Furthermore, the base plate 41 of the fixed base 4 is fixed to the edge of the feeding end of the wire feeding machine 1 by fastening bolts. Since the feeding machine has a space for placing the I-beam 2, the purpose of the fixed base 4 is to provide a fixed mounting position for the adjusting bracket 5 so as to facilitate the visual inspection device 6 to inspect the paper 3 on the I-beam 2.

[0025] In some embodiments, the adjusting bracket 5 is a three-axis linear slide module, wherein the X-axis moving unit is disposed on the top surface of the fixed plate 43, the Y-axis moving unit is disposed on the slide of the X-axis moving unit, and the Z-axis moving unit is disposed on the slide of the Y-axis moving unit.

(The adjustment bracket 5 adopts a three-axis linear slide module with a slide travel range of: X-axis: 250mm, Y-axis: 260mm, Z-axis: 120mm). The coordinate axis positions are adjusted according to the light intensity at the location of the wire feeding machine to achieve the best performance. A vision inspection device 6 is installed at the top of the adjustment bracket 5.

[0027] The visual inspection device 6 in this embodiment integrates an industrial camera and an image processor. The industrial camera captures images of the paper 3 in real time. The image processor generates control signals based on the captured images of the paper 3 and the shadow area of ​​the paper 3, and sends the relevant position information to the winding machine control system. The winding machine control system reacts to the received joint signal, decelerates in advance, stops and alarms after reaching the given position, thus realizing the function of automatic detection of welding wire joints. It should be noted that the technical solution for which protection is sought in this embodiment is the structural part of the entire device. The visual inspection device 6 is directly purchased. The data processing of the image processor and the information interaction between the image processor and the control system are not considered as technical improvements in this application. This embodiment is only used to explain the relevant technical descriptions involved in the detection principle, so they will not be elaborated further.

[0028] In addition, considering the cost of use, the adjustment bracket 5 in this embodiment adopts a manually adjustable three-axis linear slide module. If the cost of use is not considered, a three-axis cantilever linear module or a three-axis CNC screw slide linear module can also be used.

The fastening bolts pass through the mounting holes to install the fixing parts 81 on the base plate 41. The other end of the protective net 8 extends outward with an overlapping part 82, which is fixedly connected to the welding wire take-up machine by fastening bolts. The protective net 8 also has a clearance opening 83 reserved for inspection by the visual inspection device 6.

[0032] Specifically, in this embodiment, a wire protection net 8 is installed between the wire feeding machine and the wire taking machine to prevent the wire tip from flying due to joint breakage during the wire operation, thus protecting the operators. At the same time, the workers also have a clearance opening 83 on the protective net 8, so as not to affect the detection field of the visual inspection device 6, so as not to affect the detection results.
