Description

Technical Field

[0001] This application belongs to the technical field of wire electrode detection, and particularly relates to an automatic dotting detection device for wire electrodes. Background Art

[0002] A wire electrode is a metal wire used as a filler metal or simultaneously as a conductive wire. During gas welding and tungsten inert gas arc welding, the wire electrode is used as a filler metal; during submerged arc welding, electroslag welding, and other gas metal arc welding processes, the wire electrode is both a filler metal and a conductive electrode. Since the wire electrode is a filler material during the welding process, the quality of the wire electrode directly affects the strength and reliability of the welded joint. The linearity of the wire electrode is an important evaluation for determining whether the physical and chemical properties of the wire electrode are uniform. It can promptly detect potential defects in the wire electrode, such as cracks and inclusions, to prevent these defects from being introduced into the weld during the welding process. By preventing welding defects, the integrity and safety of the welded structure can be improved. As a result, it is necessary to conduct sampling linearity detection on wire electrodes produced in the same batch before leaving the factory to ensure the quality of the wire electrodes leaving the factory.

[0003] Currently, when performing linearity detection on wire electrodes, manual wire extraction is usually adopted. Then, the starting end of the wire electrode is made to be vertically downward and in contact with the detection paper located below the wire electrode. Since the hand of the operator may shake during the manual wire extraction process, it affects the accuracy of the linearity detection of the wire electrode. Moreover, the dry extension height of the wire electrode during wire feeding cannot be guaranteed, which also affects the accuracy of the linearity detection of the wire electrode. At the same time, the detection efficiency of manual wire extraction is relatively low. Summary of the Invention

[0004] This application provides an automatic dotting detection device for wire electrodes to improve the accuracy and efficiency of the linearity detection of wire electrodes.

[0005] The technical solution adopted in this application is as follows:

[0006] An automatic dotting detection device for wire electrodes, comprising:

[0007] A frame, the frame has a first platform and a second platform located below the first platform, and the first platform is provided with a through hole for the wire electrode to pass through;

[0008] A wire feeding mechanism for feeding the wire electrode and disposed on the top of the first platform;

[0009] A welding torch head located between the first platform and the second platform, and the welding torch head is coaxially arranged with the through hole;

[0010] A support arm, the support arm is located between the first platform and the second platform, the welding gun head is arranged on the support arm, and the support arm can drive the welding gun head to move between the first platform and the second platform to adjust the dry extension height of the welding wire;

[0011] An imaging mechanism is disposed between the first platform and the second platform and located at the side of the welding gun head, and is used to image the scene at the bottom of the welding gun head as a picture or video and transmit it to a display system.

[0012] By adopting the above technical solution, when detecting the linearity of the welding wire, the detection paper is first placed on the second platform and located directly below the welding gun head, and then the starting end of the welding wire is passed through the wire feeding mechanism so that the wire feeding mechanism transports the welding wire. Then, the welding wire passes through the through hole under the action of the wire feeding mechanism and extends out through the welding gun head. Then, the wire feeding mechanism continues to transport the welding wire until the welding wire hits the detection paper. At this time, the imaging mechanism images the scene at the bottom of the welding gun head as a picture or video and transmits it to the display system, so that the contact position of the starting end of the welding wire and the detection paper is displayed on the display system for the staff to view and analyze the linearity of the welding wire.

[0013] In the process of detecting the linearity of the welding wire, the phenomenon of the need for the staff to manually draw the wire is avoided, so as to improve the wire feeding efficiency of the welding wire, thereby improving the detection efficiency of the welding wire; and the influence of the possible shaking of the staff's hands on the accuracy of the linear detection of the welding wire is avoided, so as to improve the accuracy of the linear detection of the welding wire; in addition, when adjusting different types of welding wires, it is only necessary to adjust the support arm to adjust the wire extension height of the welding wire, thereby ensuring the wire extension height of the welding wire, so as to further improve the accuracy of the linear detection of the welding wire; and, by imaging the scene at the bottom of the welding gun head as a picture or video, it is also convenient for the staff to observe the relationship between the starting end of the welding wire and the detection paper, so as to greatly reduce the influence of the staff's different observation angles or positions on the linear detection of the welding wire, thereby further improving the accuracy of the linear detection of the welding wire.

[0014] Optionally, the first platform is provided with a hollow rotating platform, the center hole of the hollow rotating platform is coaxially arranged with the through hole, the wire feeding mechanism is connected to the rotating end of the hollow rotating platform, and the first platform is provided with a driving member, and the driving member is transmission-connected to the input end of the hollow rotating platform.

[0015] By adopting the above technical solution, since the central hole of the hollow rotary table is coaxially arranged with the through hole, and the wire feeding mechanism is connected to the rotating end of the hollow rotary table, the wire feeding mechanism can then rotate circumferentially around the through hole under the action of the driving member to adjust the wire feeding angle, thereby increasing the flexibility of the automatic wire feeding dot detection device and meeting the detection of the linear influence of the wire feeding at various angles to further improve the accuracy of the wire linear detection.

[0016] Optionally, the frame is provided with a driving structure for driving the support arm to move between the first platform and the second platform.

[0017] By adopting the above technical solution, since the driving structure is used to drive the support arm to move between the first platform and the second platform, the automatic adjustment of the support arm can be realized, so as to avoid the need for manual adjustment of the support arm, reduce the workload of the staff, and thus improve the efficiency of the wire linear detection; at the same time, the accuracy of the adjustment of the wire extension height of the wire is improved to further improve the accuracy of the wire linear detection.

[0018] Optionally, the support arm includes a connecting member and a supporting member connected to the connecting member. The welding torch head is arranged at one end of the supporting member away from the connecting member. The frame is provided with a guide rail, and the connecting member is provided with a slider slidably connected to the guide rail. The driving structure is used to drive the connecting member to move.

[0019] By adopting the above technical solution, when adjusting the support arm, the driving structure drives the connecting member, and then the connecting member drives the supporting member to move to realize the adjustment of the support arm. At the same time, the connecting member drives the slider to move, and the slider slides relative to the guide rail, so that the sliding fit between the slider and the guide rail can guide the movement of the support arm to increase the stability of the support arm during movement. In addition, the sliding connection between the support arm and the frame is realized.

[0020] Optionally, the driving structure includes a lead screw, a transmission block threadedly connected to the lead screw, and a power member for driving the lead screw to rotate. The transmission block is fixedly connected to the connecting member.

[0021] By adopting the above technical solution, when adjusting the position of the support arm, the power component is activated, and then the power component drives the lead screw, causing the lead screw to rotate. The transmission block rotates threadedly with the lead screw, causing the transmission block to move along the axial direction of the lead screw. Thus, the transmission block drives the connecting component to move between the first platform and the second platform, and the connecting component drives the supporting component to move between the first platform and the second platform to achieve the adjustment of the support arm. Since the adjustment of the support arm is realized by using the lead screw and the transmission block in this application, the adjustment efficiency of the support arm is improved, and the accuracy of the adjustment of the support arm is increased to ensure the accuracy of the wire feeding dry extension height of the welding wire.

[0022] Optionally, the connecting component is provided with a position sensor, and the frame is provided with a plurality of shielding plates corresponding to the position sensor. When the position sensor faces the corresponding shielding plate, the position sensor sends a stop signal to the driving structure to make the driving structure stop driving the connecting component to move.

[0023] And / or, the support arm further includes a strengthening component. One end of the strengthening component is located at the bottom of the supporting component away from the connecting component, and the other end of the strengthening component is snap-connected to the connecting component from the top of the connecting component.

[0024] By adopting the above technical solution, when adjusting the support arm, the connecting component drives the position sensor to move. When the position sensor faces the corresponding shielding plate, the position sensor sends a stop signal to the driving structure, and then the driving structure stops driving the connecting component to move, so as to realize the automatic control of the movement position of the support arm, thereby increasing the accuracy of the movement position of the support arm to ensure the accuracy of the wire feeding dry extension height of the welding wire, and further ensuring the accuracy of the linear detection of the welding wire.

[0025] Since one end of the strengthening component is located at the bottom of the supporting component away from the connecting component, and the other end of the strengthening component is snap-connected to the connecting component from the top of the connecting component, the strengthening component supports the end of the supporting component away from the connecting component, so that the supporting component remains horizontal, thereby keeping the welding torch head vertical, avoiding the influence on the accuracy of the linear detection of the welding wire due to the drooping of the end of the supporting component away from the connecting component, and further improving the accuracy of the linear detection of the welding wire.

[0026] Optionally, the support arm is provided with a gas shear at the bottom of the welding torch head, and the gas shear can cut the welding wire extending out of the welding torch head.

[0027] By adopting the above technical solution, since the support arm is provided with a gas shear at the bottom of the welding torch head, the gas shear can be used to cut the detected welding wire, so that the subsequent welding wire can continue to move downward under the action of the wire feeding mechanism, so as to realize continuous detection of the welding wire, avoid the phenomenon that the welding wire needs to be cut manually, improve the efficiency of linear detection of the welding wire, and reduce the workload of the staff at the same time.

[0028] Optionally, the second platform is provided with a blanking port on the side of the welding torch head, and the second platform is provided with a telescopic member. An electromagnet is arranged at the telescopic end of the telescopic member. When the telescopic member is in the extended state, the electromagnet can move to directly below the welding torch head under the action of the telescopic end to magnetically adsorb the welding wire. When the telescopic member is in the retracted state, the electromagnet can move to the blanking port under the action of the telescopic end and release the magnetic adsorption of the welding wire.

[0029] By adopting the above technical solution, before cutting the welding wire, first drive the telescopic member so that the telescopic end of the telescopic member drives the electromagnet to move to the position where the welding wire is located, then energize the electromagnet to make the electromagnet magnetically adsorb the welding wire, then the gas shear cuts the welding wire, and then the telescopic end of the telescopic member drives the electromagnet to retract, so that the electromagnet drives the welding wire to move to the blanking port, and then stop power supply to the electromagnet to make the electromagnet lose the magnetic adsorption force on the welding wire. The welding wire separates from the electromagnet under the action of its own gravity and falls through the blanking port, so as to avoid the phenomenon that the cut welding wire falls on the second platform and affects the subsequent detection of the welding wire, thus ensuring the accuracy of linear detection of the welding wire, and at the same time avoiding the phenomenon that the welding wire needs to be taken out manually, reducing the workload of the staff, and improving the efficiency of linear detection of the welding wire.

[0030] Optionally, the frame is provided with a universal adjusting arm, and the imaging mechanism is arranged on the universal adjusting arm.

[0031] By adopting the above technical solution, since the frame is provided with a universal adjusting arm and the imaging mechanism is arranged on the universal adjusting arm, the position irradiated by the imaging mechanism can be adjusted, so as to increase the flexibility of the imaging mechanism, and at the same time reduce the difficulty of adjusting the imaging mechanism, so as to achieve the effect of facilitating the adjustment of the imaging mechanism.

[0032] Optionally, the second platform is provided with a positioning pin directly below the welding torch head, and the positioning pin is used for positioning the detection paper.

[0033] By adopting the above technical solution, since the second platform is provided with a positioning pin located under the welding gun head, the detection paper can be passed through the positioning pin and the positioning pin is used to position the detection paper, thereby avoiding the phenomenon that the detection paper moves relative to the second platform under the action of the welding wire when linear detection of the welding wire is performed, so as to ensure the accuracy of the linear detection of the welding wire.

[0034] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0053] Referring to Figures 1 to 7 , a wire automatic dotting detection device is disclosed, which includes a frame 1, a wire feeding mechanism 2, a welding gun head 3, a support arm 4 and an imaging mechanism 5. The frame 1 has a first platform 11 and a second platform 12 located below the first platform 11, and the first platform 11 is provided with a through hole for the wire to pass through; the wire feeding mechanism 2 is used for conveying the wire and is arranged on the top of the first platform 11; the welding gun head 3 is located between the first platform 11 and the second platform 12, and the welding gun head 3 is coaxially arranged with the through hole; the support arm 4 is located between the first platform 11 and the second platform 12, the welding gun head 3 is arranged on the support arm 4, and the support arm 4 can drive the welding gun head 3 to move between the first platform 11 and the second platform 12 to adjust the dry extension height of the wire feeding; the imaging mechanism 5 is arranged between the first platform 11 and the second platform 12 and on the side of the welding gun head 3, and the imaging mechanism 5 is used for imaging the scene at the bottom of the welding gun head 3 into a picture or video and transmitting it to the display system.

[0054] When detecting the linearity of the wire, first place the detection paper on the second platform 12 and make it directly below the welding gun head 3, then pass the starting end of the wire through the wire feeding mechanism 2 so that the wire feeding mechanism 2 conveys the wire, and then the wire passes through the through hole under the action of the wire feeding mechanism 2 and extends out through the welding gun head 3, and then the wire feeding mechanism 2 continues to convey the wire until the starting end of the wire touches the detection paper. At this time, the imaging mechanism 5 images the scene at the bottom of the welding gun head 3 into a picture or video and transmits it to the display system, so that the scene at the contact position between the starting end of the wire and the detection paper is displayed on the display system for the staff to view and analyze the linearity of the wire.

[0055] In the process of detecting the linearity of the welding wire, the phenomenon of the need for the staff to manually draw the wire is avoided, so as to improve the wire feeding efficiency of the welding wire, thereby improving the detection efficiency of the welding wire; and the influence of the possible shaking of the staff's hands on the accuracy of the linear detection of the welding wire is avoided, so as to improve the accuracy of the linear detection of the welding wire; in addition, when adjusting different types of welding wires, it is only necessary to adjust the support arm 4 to adjust the wire extension height of the welding wire, thereby ensuring the wire extension height of the welding wire, so as to further improve the accuracy of the linear detection of the welding wire; and, by imaging the scene at the bottom of the welding gun head 3 as a picture or video, it is also convenient for the staff to observe the relationship between the starting end of the welding wire and the detection paper, so as to greatly reduce the influence of the staff's observation angle or position on the linear detection of the welding wire, thereby further improving the accuracy of the linear detection of the welding wire.

[0056] It should be noted that the display system mentioned in the present application may be a display, or it may be a processor with storage and display functions.

[0057] The present application does not specifically limit the structure of the imaging mechanism 5 , which may be a camera, a video camera, or other equipment with a camera function.

[0058] In a preferred embodiment, referring to Figures 1 to 3 The first platform 11 is provided with a hollow rotating platform 111, the center hole of the hollow rotating platform 111 is coaxially arranged with the through hole, the wire feeding mechanism 2 is connected to the rotating end of the hollow rotating platform 111, and the first platform 11 is provided with a driving member 112, which is transmission-connected to the input end of the hollow rotating platform 111.

[0059] Since the center hole of the hollow rotating platform 111 is coaxially arranged with the through hole, and the wire feeding mechanism 2 is connected to the rotating end of the hollow rotating platform 111, the wire feeding mechanism 2 can rotate circumferentially around the through hole under the action of the driving member 112 to adjust the wire feeding angle, thereby increasing the flexibility of the automatic spot detection device for welding wire, and at the same time satisfying the detection of the linear influence of various wire feeding angles on the welding wire, so as to further improve the accuracy of the linear detection of the welding wire.

[0060] Better, refer to Figures 1 to 3 The rotating end of the hollow rotating platform 111 is fixedly connected to a mounting plate 113, and the wire feeding mechanism 2 is fixedly connected to the mounting plate 113, so that the wire feeding mechanism 2 and the center hole of the hollow rotating platform 111 form an avoidance to ensure the smoothness of the welding wire transportation.

[0061] The present application does not specifically limit the structure of the driving member 112. Preferably, refer to Figure 3The driving member 112 is a servo motor disposed at the bottom of the first platform 11. The output shaft of the servo motor is connected to the input end of the hollow rotating platform 111 through a coupling to drive the wire feeding mechanism 2 to rotate a set angle, so as to improve the accuracy of the linear detection of the welding wire. In other implementation examples, the driving member 112 can also be a pneumatic motor or other structure that can drive the hollow rotating platform 111 to rotate.

[0062] The present application does not specifically limit the adjustment method of the support arm 4. Preferably, refer to Figure 1 , Figure 2 and Figure 4 The frame 1 is provided with a driving structure 13, and the driving structure 13 is used to drive the supporting arm 4 to move between the first platform 11 and the second platform 12.

[0063] Since the driving structure 13 is used to drive the support arm 4 to move between the first platform 11 and the second platform 12, the support arm 4 can be automatically adjusted to avoid the need for manual adjustment of the support arm 4, thereby reducing the workload of the staff and improving the efficiency of the linear detection of the welding wire; at the same time, the accuracy of the adjustment of the wire extension height is improved to further improve the accuracy of the linear detection of the welding wire.

[0064] Further, see Figure 1 and Figure 4 The support arm 4 includes a connecting member 41 and a supporting member 42 connected to the connecting member 41. The welding gun head 3 is arranged at one end of the supporting member 42 away from the connecting member 41. The frame 1 is provided with a guide rail 14. The connecting member 41 is provided with a slider 411 slidably connected to the guide rail 14. The driving structure 13 is used to drive the connecting member 41 to move.

[0065] It can be understood that the guide rail 14 is disposed between the first platform 11 and the second platform 12 , and the guide rail 14 is disposed perpendicular to the first platform 11 and the second platform 12 , so that the support arm 4 moves between the first platform 11 and the second platform 12 .

[0066] When adjusting the support arm 4, the driving structure 13 drives the connecting member 41, and then the connecting member 41 drives the supporting member 42 to move to adjust the support arm 4. At the same time, the connecting member 41 drives the slider 411 to move, and the slider 411 and the guide rail 14 slide relative to each other, so that the sliding cooperation between the slider 411 and the guide rail 14 can guide the movement of the support arm 4 to increase the stability of the support arm 4 during movement. In addition, the sliding connection between the support arm 4 and the frame 1 is also realized.

[0067] The present application does not make any specific limitation on the driving structure 13. Preferably, refer to Figure 4, the driving structure 13 includes a lead screw 131, a transmission block 132 threadedly connected to the lead screw 131, and a power member 133 for driving the lead screw 131 to rotate. The transmission block 132 is fixedly connected to the connecting member 41.

[0068] When adjusting the position of the support arm 4, the power member 133 is started, and then the power member 133 drives the lead screw 131 to rotate the lead screw 131. The transmission block 132 and the lead screw 131 perform a threaded rotation, so that the transmission block 132 moves along the axial direction of the lead screw 131, so that the transmission block 132 drives the connecting member 41 to move between the first platform 11 and the second platform 12, and the connecting member 41 drives the support member 42 to move between the first platform 11 and the second platform 12 to realize the adjustment of the support arm 4; since the adjustment of the support arm 4 is realized by using the lead screw 131 and the transmission block 132 in this application, the adjustment efficiency of the support arm 4 is improved, and the accuracy of the adjustment of the support arm 4 is increased to ensure the accuracy of the wire feeding dry extension height of the welding wire.

[0069] The structure of the power member 133 in this application is not specifically limited. Preferably, the power member 133 is a servo motor to realize precise control of the lead screw 131, so that the support arm 4 can accurately move to the required position to improve the accuracy of the linear detection of the welding wire. In other embodiments, the power member 133 can also be a pneumatic motor or other structures capable of driving the lead screw 131 to rotate.

[0070] Further, referring to Figure 1 and Figure 2 , the connecting member 41 is provided with a position sensor 412, and the frame 1 is provided with a plurality of shielding plates 15 corresponding to the position sensor 412. When the position sensor 412 faces the corresponding shielding plate 15, the position sensor 412 sends a stop signal to the driving structure 13 to make the driving structure 13 stop driving the connecting member 41 to move.

[0071] It can be understood that the automatic dotting detection device for the welding wire further includes a control system. The position sensor 412 is electrically connected to the control system, and the power member 133 of the driving structure 13 is electrically connected to the control system to be able to control the power member 133 by using the position sensor 412.

[0072] When adjusting the support arm 4, the connecting member 41 drives the position sensor 412 to move. When the position sensor 412 faces the corresponding shielding plate 15, the position sensor 412 sends a stop signal to the driving structure 13, and then the driving structure 13 stops driving the connecting member 41 to move to realize automatic control of the movement position of the support arm 4, thereby increasing the accuracy of the movement position of the support arm 4 to ensure the accuracy of the wire feeding dry extension height of the welding wire, and further ensuring the accuracy of the linear detection of the welding wire.

[0073] In other embodiments, the driving structure 13 may also be a hydraulic cylinder, a pneumatic cylinder, an electric push rod, or other structures capable of driving the support arm 4 to move.

[0074] Further, referring to Figure 5 , the support arm 4 further includes a strengthening member 43. One end of the strengthening member 43 is located at the bottom of the support member 42 away from the connecting member 41, and the other end of the strengthening member 43 is snap-connected to the connecting member 41 from the top of the connecting member 41.

[0075] Specifically, referring to Figure 4 , a connecting pipe 421 is provided at one end of the support member 42 away from the connecting member 41. The welding torch head 3 is arranged inside the connecting pipe 421, and the connecting pipe 421 is provided with bolts for fastening the welding torch head 3, thereby increasing the gravity at one end of the support member 42 away from the connecting member 41, so there is a risk that one end of the support member 42 away from the connecting member 41 may sag.

[0076] Since one end of the strengthening member 43 is located at the bottom of the support member 42 away from the connecting member 41, and the other end of the strengthening member 43 is snap-connected to the connecting member 41 from the top of the connecting member 41, the strengthening member 43 then supports one end of the support member 42 away from the connecting member 41, so that the support member 42 is kept in a horizontal state, thereby enabling the welding torch head 3 to be kept in a vertical state, so as to avoid the influence on the accuracy of the wire linearity detection due to the sagging of one end of the support member 42 away from the connecting member 41, and further improving the accuracy of the wire linearity detection.

[0077] This application does not specifically limit the structure of the strengthening member 43. Preferably, referring to Figure 5 , the strengthening member 43 includes a first strengthening piece 431 and second strengthening pieces 432 located at both ends of the first strengthening piece 431. The first strengthening piece 431 is located at the bottom of the support member 42, and the two second strengthening pieces 432 are respectively located on both sides of the support member 42. Connecting grooves 433 for accommodating the connecting member 41 are provided at the ends of the two second strengthening pieces 432 away from the first strengthening piece 431, and the notch of the connecting groove 433 faces downward, so as to support one end of the support member 42 away from the connecting member 41, thereby avoiding the phenomenon of sagging of one end of the support member 42 away from the connecting member 41, so as to improve the accuracy of the wire linearity detection. In other implementation examples, the strengthening member 43 may also be other structures, such as a rod-shaped structure.

[0078] In other embodiments, the support arm 4 can also be adjusted manually to reduce the production cost of the wire automatic dotting detection device.

[0079] In a preferred embodiment, referring to Figure 1 、Figure 2 and Figure 4 The support arm 4 is provided with a gas shear 423 located at the bottom of the welding torch head 3, and the gas shear 423 can cut the welding wire extending out of the welding torch head 3.

[0080] Since the support arm 4 is provided with the gas shear 423 located at the bottom of the welding torch head 3, the gas shear 423 can be used to cut the detected welding wire, so that the subsequent welding wire can continue to move downward under the action of the wire feeding mechanism 2 to realize continuous detection of the welding wire, avoiding the need for manual cutting of the welding wire, thereby improving the efficiency of linear detection of the welding wire and reducing the workload of the staff at the same time.

[0081] Specifically, the gas shear 423 is arranged at one end of the support member 42 far from the connecting member 41, so that the gas shear 423 can directly cut the welding wire when working, avoiding the need to drive the gas shear 423 to move when cutting the welding wire, and improving the cutting efficiency of the welding wire.

[0082] Further, referring to Figure 1 、 Figure 2 and Figure 7 The second platform 12 is provided with a blanking port 121 located at the side of the welding torch head 3, and the second platform 12 is provided with a telescopic member 122. An electromagnet 123 is arranged at the telescopic end of the telescopic member 122. When the telescopic member 122 is in the extended state, the electromagnet 123 can move to directly below the welding torch head 3 under the action of the telescopic end to magnetically adsorb the welding wire. When the telescopic member 122 is in the retracted state, the electromagnet 123 can move to the blanking port 121 under the action of the telescopic end and release the magnetic adsorption on the welding wire.

[0083] Before cutting the welding wire, first drive the telescopic member 122 so that the telescopic end of the telescopic member 122 drives the electromagnet 123 to move to the position where the welding wire is located, then energize the electromagnet 123 so that the electromagnet 123 magnetically adsorbs the welding wire, then the gas shear 423 cuts the welding wire, and then the telescopic end of the telescopic member 122 drives the electromagnet 123 to do a retracting movement, so that the electromagnet 123 drives the welding wire to move to the blanking port 121, and then stop powering the electromagnet 123, so that the electromagnet 123 loses the magnetic adsorption force on the welding wire, and the welding wire separates from the electromagnet 123 under the action of its own gravity and falls through the blanking port 121, avoiding the phenomenon that the cut welding wire falls on the second platform 12 and affecting the subsequent detection of the welding wire, thus ensuring the accuracy of linear detection of the welding wire, and at the same time avoiding the need for manual removal of the welding wire, reducing the workload of the staff and improving the efficiency of linear detection of the welding wire.

[0084] Preferably, referring to Figure 7, there are two telescopic members 122 disposed opposite to each other, and there are two blanking ports 121. An electromagnet 123 is provided at the telescopic end of each telescopic member 122 to avoid the situation where the welding wire cannot be driven to the blanking port 121 due to the failure of a single telescopic member 122 or electromagnet 123, thereby ensuring the efficiency of the linear detection of the welding wire.

[0085] Furthermore, referring to Figure 7 , a material guiding hopper 124 is provided at the bottom of the second platform 12. The top view projections of the two blanking ports 121 are both located within the material guiding hopper 124, so that the welding wire falling through the blanking port 121 falls to the same position under the guiding action of the material guiding hopper 124, in order to achieve the effect of collecting and cleaning the welding wire.

[0086] This application does not specifically limit the structure of the telescopic member 122. Preferably, the telescopic member 122 is a cylinder. The cylinder block of the cylinder is fixedly connected to the second platform 12, and the electromagnet 123 is provided on the piston rod of the cylinder, so as to reduce the production cost of the automatic dotting detection device for the welding wire and ensure the stability of the automatic dotting detection device for the welding wire. In other embodiments, the telescopic member 122 can also be other structures such as a hydraulic cylinder, an electric push rod, etc.

[0087] In a preferred embodiment, referring to Figure 2 , the support arm 4 is provided with a guiding tube 422 located above the welding torch head 3. The guiding tube 422 is coaxially arranged with the through hole, so as to be able to guide the welding wire, so that the welding wire conveyed by the wire feeding mechanism 2 extends out through the welding torch head 3 under the action of the guiding tube 422, in order to avoid the situation where the welding wire needs to be manually passed through the welding torch head 3, thereby further reducing the workload of the staff and improving the efficiency of the linear detection of the welding wire.

[0088] In a preferred embodiment, referring to Figure 6 , the frame 1 is provided with a universal adjusting arm 16, and the imaging mechanism 5 is arranged on the universal adjusting arm 16, and then the position irradiated by the imaging mechanism 5 can be adjusted, so as to increase the flexibility of the imaging mechanism 5, and at the same time reduce the difficulty of adjusting the imaging mechanism 5, so as to achieve the effect of facilitating the adjustment of the imaging mechanism 5.

[0089] This application does not specifically limit the structure of the universal adjusting arm 16. Preferably, the universal adjusting arm 16 is a structure composed of multiple rod-shaped structures and block-shaped structures, so as to improve the supporting effect on the imaging mechanism 5 and achieve the effect of facilitating the adjustment of the imaging mechanism 5; and, the block-shaped structure at the end is connected to the frame 1 through a butterfly bolt pair. The frame 1 is provided with a waist-shaped groove extending in the vertical direction, and the bolt of the butterfly bolt pair passes through the waist-shaped groove, so as to further increase the adjustment range of the imaging mechanism 5.

[0090] In other embodiments, the universal adjusting arm 16 can also be other structures.

[0091] In a preferred embodiment, with reference to Figure 7 , the second platform 12 is provided with a positioning pin 125 directly below the welding torch head 3, and the positioning pin 125 is used to position the test paper.

[0092] Since the second platform 12 is provided with the positioning pin 125 below the welding torch head 3, the test paper can then be passed through the positioning pin 125 to use the positioning pin 125 to position the test paper, thereby avoiding the phenomenon that the test paper moves relative to the second platform 12 under the action of the welding wire during the linear detection of the welding wire, so as to ensure the accuracy of the linear detection of the welding wire.

[0093] The structure of the positioning pin 125 in this application is not specifically limited. Preferably, the positioning pin 125 includes a pin base and a pin head provided on the pin base. The second platform 12 is provided with a receiving cavity for receiving the pin base, and the pin base is arranged in the receiving cavity to achieve the effect of facilitating the replacement of the positioning pin 125. In other embodiments, the positioning pin 125 can also be a pin body fixedly connected to the second platform 12.
