Description

Technical Field

[0001] The present application belongs to the technical field of welding wire detection, and specifically relates to an automatic spot detection device for welding wire. Background Art

[0002] Welding wire is a metal wire used as filler metal or as a conductor at the same time. In gas welding and tungsten arc welding, welding wire is used as filler metal; in submerged arc welding, electroslag welding and other metal arc welding, welding wire is both filler metal and conductive electrode. Since welding wire is used as a filler material in the welding process, its quality directly affects the strength and reliability of the welded joint. The linearity of welding wire is an important evaluation of whether the physical and chemical properties of welding wire are uniform. It can timely detect potential defects in welding wire, such as cracks, inclusions, etc., to avoid these defects being introduced into the weld during the welding process. By preventing welding defects, the integrity and safety of the welded structure can be improved. This leads to the need to conduct sampling linearity testing on welding wires produced in the same batch before they leave the factory to ensure the factory quality of welding wires.

[0003] At present, when performing linear detection on welding wire, manual wire drawing is usually adopted, and then the starting end of the welding wire is made to face vertically downward and contact the detection paper under the welding wire. Since the hands of the staff may shake during the manual wire drawing process, the accuracy of the linear detection of the welding wire is affected, and the dry depth of the welding wire cannot be guaranteed, which also affects the accuracy of the linear detection of the welding wire. At the same time, the detection efficiency of manual wire drawing is low. Summary of the invention

[0004] The present application provides an automatic spot detection device for welding wire to improve the accuracy and efficiency of linear detection of welding wire.

[0005] The technical solution adopted in this application is: A welding wire automatic spot detection device, comprising: A frame, wherein 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 welding wire to pass through; A wire feeding mechanism, which is used to feed the welding wire and is disposed on the top of the first platform; A welding gun head, the welding gun head is located between the first platform and the second platform, and the welding gun head is coaxially arranged with the through hole; 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 depth height of the welding wire; 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.

[0006] 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.

[0007] 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 dry depth of the welding wire, thereby ensuring the dry depth 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.

[0013] By adopting the above technical solution, when the support arm is adjusted, the driving structure drives the connecting component, and then the connecting component drives the supporting component to move to achieve the adjustment of the support arm. At the same time, the connecting component drives the slider to move, and the slider and the guide rail slide relative to each other, so that the sliding cooperation 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, a sliding connection between the support arm and the frame is achieved.

[0014] Optionally, the driving structure includes a lead screw, a transmission block threadedly connected to the lead screw, and a power member driving the lead screw to rotate, and the transmission block is fixedly connected to the connecting member.

[0015] By adopting the above technical solution, when adjusting the position of the support arm, the power part is started, and then the power part drives the lead screw to rotate, and the transmission block and the lead screw are threadedly rotated, so that the transmission block moves along the axial direction of the lead screw, so that the transmission block drives the connecting member to move between the first platform and the second platform, and the connecting member drives the support member to move between the first platform and the second platform to achieve the adjustment of the support arm; since the lead screw and the transmission block are used to adjust the support arm 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 height of the wire outlet depth.

[0018] Since one end of the reinforcing member is located at the bottom of the end of the supporting member away from the connecting member, the other end of the reinforcing member is clamped to the connecting member from the top of the connecting member, and then the reinforcing member supports the end of the supporting member away from the connecting member, so that the supporting member remains in a horizontal state, thereby keeping the welding gun head in a vertical state, so as to avoid the influence on the accuracy of the linear detection of the welding wire due to the drooping of the end of the supporting member away from the connecting member, thereby further improving the accuracy of the linear detection of the welding wire.

[0019] Optionally, the support arm is provided with a gas shear located at the bottom of the welding gun head, and the gas shear can cut the welding wire extending out of the welding gun head.

[0020] By adopting the above technical solution, since the support arm is provided with a gas shear located at the bottom of the welding gun head, the gas shear can be used to cut the welding wire that has been inspected, so that the subsequent welding wire can continue to move downward under the action of the wire feeding mechanism, so as to achieve continuous inspection of the welding wire and avoid the need to manually cut the welding wire, thereby improving the efficiency of linear inspection of the welding wire and reducing the workload of the staff.

[0022] By adopting the above technical scheme, before cutting the welding wire, the telescopic part is first driven so that the telescopic end of the telescopic part drives the electromagnet to move to the position of the welding wire, and then the electromagnet is energized to make the electromagnet magnetically absorb the welding wire, and then the gas shear cuts the welding wire again, and then the telescopic end of the telescopic part drives the electromagnet to retract, so that the electromagnet drives the welding wire to the blanking port, and then the power supply to the electromagnet is stopped to make the electromagnet lose its magnetic adsorption force on the welding wire, and the welding wire is separated from the electromagnet under the action of its own gravity and falls through the blanking port to avoid the phenomenon that the cut welding wire falls on the second platform and affects the subsequent detection of the welding wire, thereby ensuring the accuracy of the linear detection of the welding wire and avoiding the phenomenon that the welding wire needs to be taken out manually, so as to reduce the workload of the staff and improve the efficiency of the linear detection of the welding wire.

[0023] Optionally, the frame is provided with a universal adjustment arm, and the imaging mechanism is arranged on the universal adjustment arm.

[0037] Reference Figures 1 to 7 , discloses an automatic spot detection device for welding wire, which includes a frame 1, a wire feeding mechanism 2, a welding gun head 3, a support arm 4 and an imaging mechanism 5, wherein 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 welding wire to pass through; the wire feeding mechanism 2 is used to transport the welding 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 depth height of the welding wire; 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 to image the scene at the bottom of the welding gun head 3 as a picture or video and transmit it to a display system.

[0038] When detecting the linearity of the welding 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 welding wire through the wire feeding mechanism 2, so that the wire feeding mechanism 2 can transport the welding wire, and then make the welding wire pass through the through hole under the action of the wire feeding mechanism 2 and extend through the welding gun head 3, and then the wire feeding mechanism 2 continues to transport the welding wire until the starting end of the welding wire hits the detection paper. At this time, the imaging mechanism 5 images the scene at the bottom of the welding gun head 3 as a picture or video and transmits it to the display system, so that the scene of the contact position between 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.

[0039] 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 height of the dry depth of the welding wire, thereby ensuring the dry depth 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] The present application does not specifically limit the structure of the driving member 112. Preferably, refer to Figure 3 The 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.

[0046] 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.

[0047] 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 outlet depth height is improved to further improve the accuracy of the linear detection of the welding wire.

[0048] 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.

[0049] 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 .

[0050] 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.

[0051] 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 driving the lead screw 131 to rotate. The transmission block 132 is fixedly connected to the connecting member 41 .

[0052] When adjusting the position of the support arm 4, the power piece 133 is started, and then the power piece 133 drives the lead screw 131 to rotate the lead screw 131, and the transmission block 132 and the lead screw 131 are threadedly rotated, 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 supporting member 42 to move between the first platform 11 and the second platform 12, so as to achieve the adjustment of the support arm 4; because the lead screw 131 and the transmission block 132 are used to adjust the support arm 4 in the present 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 height of the wire outlet depth.

[0053] The present application does not specifically limit the structure of the power member 133. Preferably, the power member 133 is a servo motor to achieve precise control of the lead screw 131, so that the support arm 4 can move accurately to the desired position to improve the accuracy of the linear detection of the welding wire. In other implementation examples, the power member 133 can also be a pneumatic motor or other structure that can drive the lead screw 131 to rotate.

[0054] Further, see Figure 1 and Figure 2The 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 is opposite to 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.

[0055] It is understandable that the welding wire automatic spot detection device also includes a control system, the position sensor 412 is electrically connected to the control system, and the power component 133 of the driving structure 13 is electrically connected to the control system so that the position sensor 412 can be used to control the power component 133.

[0056] When the support arm 4 is adjusted, the connecting member 41 drives the position sensor 412 to move. When the position sensor 412 is opposite to the corresponding baffle 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, so as 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, so as to ensure the accuracy of the wire drawing depth height, and further ensure the accuracy of the linear detection of the welding wire.

[0057] 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.

[0058] Further, see Figure 5 The support arm 4 further includes a reinforcing member 43 , one end of which is located at the bottom of the support member 42 away from one end of the connecting member 41 , and the other end of the reinforcing member 43 is clamped to the connecting member 41 from the top of the connecting member 41 .

[0059] Specifically, refer 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 gun head 3 is provided inside the connecting pipe 421, and the connecting pipe 421 is provided with bolts for fastening the welding gun head 3, thereby increasing the gravity of the end of the support member 42 away from the connecting member 41, so that there is a risk that the end of the support member 42 away from the connecting member 41 may sag.

[0060] Since one end of the reinforcing member 43 is located at the bottom of the end of the supporting member 42 away from the connecting member 41, the other end of the reinforcing member 43 is clamped to the connecting member 41 from the top of the connecting member 41, and then the reinforcing member 43 supports the end of the supporting member 42 away from the connecting member 41, so that the supporting member 42 remains in a horizontal state, thereby keeping the welding gun head 3 in a vertical state, so as to avoid the influence on the accuracy of the linear detection of the welding wire due to the drooping of the end of the supporting member 42 away from the connecting member 41, thereby further improving the accuracy of the linear detection of the welding wire.

[0061] The present application does not specifically limit the structure of the reinforcing member 43. Preferably, refer to Figure 5 The reinforcing member 43 includes a first reinforcing sheet 431 and second reinforcing sheets 432 located at both ends of the first reinforcing sheet 431. The first reinforcing sheet 431 is located at the bottom of the supporting member 42, and the two second reinforcing sheets 432 are respectively located at both sides of the supporting member 42. The ends of the two second reinforcing sheets 432 away from the first reinforcing sheet 431 are both provided with connecting grooves 433 for accommodating the connecting member 41. The notches of the connecting grooves 433 face downward to support the end of the supporting member 42 away from the connecting member 41, thereby avoiding the phenomenon that the end of the supporting member 42 away from the connecting member 41 droops, so as to improve the accuracy of the linear detection of the welding wire. In other implementation examples, the reinforcing member 43 can also be other structures, such as a rod-shaped structure.

[0062] In other embodiments, the support arm 4 may be adjusted manually to reduce the production cost of the welding wire automatic spot detection device.

[0063] 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 gun head 3, and the gas shear 423 can cut the welding wire extending out of the welding gun head 3.

[0064] Since the support arm 4 is provided with a gas shear 423 located at the bottom of the welding gun head 3, the gas shear 423 can be used to cut the welding wire after the inspection, so that the subsequent welding wire can continue to move downward under the action of the wire feeding mechanism 2, so as to realize the continuous inspection of the welding wire and avoid the need to manually cut the welding wire, thereby improving the efficiency of the linear inspection of the welding wire and reducing the workload of the staff.

[0065] Specifically, the gas shear 423 is arranged at one end of the support member 42 away from the connecting member 41, so that the gas shear 423 can directly shear the welding wire when working, so as to avoid the need to drive the gas shear 423 to move when shearing the welding wire, thereby improving the shearing efficiency of the welding wire.

[0066] Further, see Figure 1 , Figure 2 and Figure 7The second platform 12 is provided with a blanking port 121 located on the side of the welding gun head 3, and the second platform 12 is provided with a telescopic member 122, and an electromagnet 123 is provided at the telescopic end of the telescopic member 122. When the telescopic member 122 is in an extended state, the electromagnet 123 can move to the bottom of the welding gun head 3 under the action of the telescopic end so as to be able to magnetically absorb the welding wire. When the telescopic member 122 is in a retracted state, the electromagnet 123 can move to the blanking port 121 under the action of the telescopic end and release the magnetic absorption of the welding wire.

[0067] Before cutting the welding wire, the telescopic member 122 is driven first, so that the telescopic end of the telescopic member 122 drives the electromagnet 123 to move to the position of the welding wire, and then the electromagnet 123 is energized to make the electromagnet 123 magnetically absorb the welding wire, and then the gas shear 423 cuts the welding wire again, and then the telescopic end of the telescopic member 122 drives the electromagnet 123 to retract, so that the electromagnet 123 drives the welding wire to move to the blanking port 121, and then the power supply to the electromagnet 123 is stopped, so that the electromagnet 123 loses the magnetic adsorption force on the welding wire, and the welding wire is separated from the electromagnet 123 under the action of its own gravity and falls through the blanking port 121, so as to avoid the cut welding wire falling on the second platform 12 and affecting the subsequent detection of the welding wire, thereby ensuring the accuracy of the linear detection of the welding wire, and avoiding the phenomenon of manual removal of the welding wire, so as to reduce the workload of the staff and improve the efficiency of the linear detection of the welding wire.

[0068] Better, refer to Figure 7 There are two telescopic parts 122 arranged relatively to each other, and there are two blanking ports 121. An electromagnet 123 is provided at the telescopic end of each telescopic part 122 to avoid the phenomenon that the welding wire cannot be driven to the blanking port 121 due to a failure of a single telescopic part 122 or the electromagnet 123, thereby ensuring the efficiency of linear detection of the welding wire.

[0069] Further, refer to Figure 7 A guide hopper 124 is provided at the bottom of the second platform 12, and the top projections of the two drop ports 121 are both located in the guide hopper 124, so that the welding wires falling through the drop ports 121 fall to the same position under the guidance of the guide hopper 124, so as to collect and clean the welding wires.

[0070] The present application does not specifically limit the structure of the telescopic member 122. Preferably, the telescopic member 122 is a cylinder, the cylinder body of the cylinder is fixedly connected to the second platform 12, and the electromagnet 123 is provided on the piston rod of the cylinder to reduce the production cost of the automatic spot detection device for welding wires and ensure the stability of the automatic spot detection device for welding wires. In other embodiments, the telescopic member 122 can also be a hydraulic cylinder, an electric push rod, and other structures.

[0071] In a preferred embodiment, referring to Figure 2 The support arm 4 is provided with a guide tube 422 located above the welding gun head 3. The guide tube 422 is coaxially arranged with the through hole to guide the welding wire, so that the welding wire delivered by the wire feeding mechanism 2 is extended through the welding gun head 3 under the action of the guide tube 422, so as to avoid the need to manually pass the welding wire through the welding gun head 3, thereby further reducing the workload of the staff and improving the efficiency of linear detection of the welding wire.

[0072] In a preferred embodiment, referring to Figure 6 The frame 1 is provided with a universal adjustment arm 16, and the imaging mechanism 5 is arranged on the universal adjustment arm 16, so that the position irradiated by the imaging mechanism 5 can be adjusted to increase the flexibility of the imaging mechanism 5, while also reducing the difficulty of adjusting the imaging mechanism 5, so as to achieve the effect of facilitating the adjustment of the imaging mechanism 5.

[0073] The present application does not make any specific limitation on the structure of the universal adjustment arm 16. Preferably, the universal adjustment arm 16 is a structure composed of multiple rod-like structures and block-like structures to improve the supporting effect on the imaging mechanism 5 and to facilitate the adjustment of the imaging mechanism 5; and the block-like structure at the end is connected to the frame 1 through a butterfly bolt pair, and the frame 1 is provided with a waist-shaped groove extending in the vertical direction, and the bolts of the butterfly bolt pair are inserted into the waist-shaped groove to further increase the adjustment range of the imaging mechanism 5.

[0074] In other embodiments, the universal adjustment arm 16 may also be other structures.

[0075] In a preferred embodiment, referring to Figure 7 The second platform 12 is provided with a positioning pin 125 located directly below the welding gun head 3, and the positioning pin 125 is used to position the detection paper.

[0076] Since the second platform 12 is provided with a positioning pin 125 located below the welding gun head 3, the detection paper can be passed through the positioning pin 125 so as to use the positioning pin 125 to position the detection paper, thereby avoiding the phenomenon that the detection paper moves relative to the second platform 12 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.

[0077] The present application does not specifically limit the structure of the positioning needle 125. Preferably, the positioning needle 125 includes a needle seat and a needle head disposed on the needle seat. The second platform 12 is provided with a receiving cavity for accommodating the needle seat. The needle seat is disposed in the receiving cavity to facilitate replacement of the positioning needle 125. In other embodiments, the positioning needle 125 may also be a needle body fixedly connected to the second platform 12.

For those skilled in the art, the present application may have various changes and variations.
