Description

Technical Field

[0001] The present invention relates to the technical field of steel grating production, and particularly to a welding device for steel grating production and processing. Background Art

[0002] A steel grating is an iron and steel product in which flat steel is arranged crosswise at a certain interval and with cross bars, and welded into a square grid in the middle. When producing and processing steel gratings, the two ends of the steel grating form ends with longitudinally arranged flat steel, and edge-wrapping steel needs to be welded to make it neat, beautiful and convenient for use.

[0003] When welding the flat steel and the edge-wrapping steel, in order to detect the welding quality, visual inspection needs to be carried out on the weld seam between the flat steel and the edge-wrapping steel. By visual inspection, it is observed whether the weld seam meets the requirements. If it is unqualified, rework is still required. However, during visual inspection, the lens on the visual inspection device will be contaminated by the soot particle impurities generated during welding. Therefore, during inspection, the attached soot particle impurities will block the lens, thus preventing the image acquisition of the weld seam and affecting the sufficiency and accuracy during weld seam detection. Summary of the Invention

[0016] The present invention has the following beneficial effects:

[0017] 1. In the welding equipment for the production and processing of steel gratings, before the detection head moves downward to detect the weld, the detection seat drives the round rod to move downward, and the round rod drives the sliding rod to move downward along the sliding groove, so that the sliding rod drives the sliding protrusion to slide along the second track groove, so that the sliding protrusion can drive the sliding rod to move back and forth left and right once. When the sliding rod reciprocates left and right once, it drives the round rod to reciprocate left and right, and the round rod drives the roller and the cleaning cloth to reciprocate left and right, so that the cleaning cloth can wipe the lens of the detection head, which is convenient for removing smoke and dust particles attached to the lens of the detection head before detection, avoiding the obstruction of smoke and dust particles, which is beneficial to improve the adequacy and accuracy of the detection. In addition, in the process of the round rod moving left and right, the first track groove is set, so that the end of the round rod slides inside the first track groove, thereby lifting the cleaning cloth, so that the cleaning cloth does not contact the surface of the detection seat, so that before wiping the lens, the cleaning cloth will not wipe the area outside the lens, thereby increasing the cleanliness of the cleaning cloth, reducing the wear of the cleaning cloth, and helping to increase the cleaning effect.

[0018] 2. In the welding equipment for the production and processing of steel grating plates, when the cleaning cloth wipes the lens of the detection head from left to right, through the arranged moving component, a connecting column is arranged between the first rod body and the second rod body. By the sliding of the limiting block in the limiting groove, the second rod body and the first rod body can perform relative movement, so that when the second rod body moves left and right, it can perform reciprocating up and down movement at the same time. The reciprocating up and down movement of the second rod body drives the cleaning cloth to perform reciprocating up and down movement, so that the cleaning cloth can perform reciprocating up and down movement during the process of wiping the lens from left to right, which is beneficial to improving the wiping effect and further increasing the cleaning effect.

[0019] 3. In the welding equipment for the production and processing of steel grating plates, when the cleaning cloth wipes the lens of the detection head, the first rod body slides along the first track groove. When the first rod body slides to the first horizontal part of the first track groove, the gear meshes with the rack. Then when the first rod body continues to slide along the first horizontal part, it will drive the gear to move on the rack, so that the gear drives the first rod body to rotate. The rotation of the first rod body drives the second rod body to rotate, and the rotation of the second rod body drives the cylinder and the cleaning cloth to rotate, so that the cleaning cloth can rotate during the process of wiping the lens. Through the rotation of the cleaning cloth, not only can the contact surface between the cleaning cloth and the lens be changed to avoid the problem of only one part of the cleaning cloth contacting the lens, but also when the cleaning cloth rotates, the particulate impurities on the cleaning cloth on the side away from the lens are easy to fall off, thereby further increasing the cleaning effect.

Detailed implementation manners

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1. Please refer to Figures 1 - 13 , a welding device for the production and processing of steel grating plates, including a workbench 2 for fixing the plate 1, a cross plate 4 movably arranged on the workbench 2, a welding torch 5 that can move up and down below the cross plate 4, a detection seat 6 that moves synchronously with the welding torch 5 below the cross plate 4, and a detection head 7 arranged at the bottom of the detection seat 6;

[0036] A round rod 8 is slidably arranged on the detection seat 6. A cylinder 9 is fixed at the bottom end of the round rod 8. A cleaning cloth 10 is sleeved on the cylinder 9. A first positioning block 11 is fixed on the detection seat 6. A first track groove 12 for the round rod 8 to slide is opened on the first positioning block 11. The cleaning cloth 10 wipes the detection head 7 left and right along the first track groove 12 through the round rod 8;

[0037] The first track groove 12 includes an outward movement part 121, an inward movement part 122, and a first horizontal part 123 that are connected in sequence. A vertical plate 13 is fixed on the lower surface of the cross plate 4. A chute 15 is opened on the vertical plate 13. A sliding rod 14 is slidably arranged in the chute 15. A guide plate 28 is fixed at the end of the sliding rod 14. A guide groove 29 is opened on the guide plate 28. A guide block 30 is slidably connected in the guide groove 29. A limiting ring 31 sleeved on the round rod 8 is fixed at the end of the guide block 30;

[0038] A sliding protrusion 16 is fixed at the end of the sliding rod 14. A second track groove 17 for the sliding protrusion 16 to slide is opened on the inner wall of the chute 15. The second track groove 17 includes a first inclined part 171, a second inclined part 172, and a vertical part 173 that are connected in sequence;

[0039] A baffle 36 is fixed on the workbench 2. A first servo cylinder 37 is fixed on the workbench 2. A clamping plate 38 for clamping and fixing the plate 1 is fixed at the output end of the first servo cylinder 37. A slide rail 39 is fixed on the workbench 2. A side table 3 is slidably arranged on the slide rail 39. A second servo cylinder 40 for pushing the side table 3 to move is fixed on the workbench 2;

[0040] A lead screw 41 is rotatably arranged at the top of the side table 3, a servo motor 42 drivingly connected to the lead screw 41 is fixed on the surface of the side table 3, the end of the cross plate 4 is threadedly connected to the lead screw 41, a third servo cylinder 43 is fixed on the lower surface of the cross plate 4, and an output end of the third servo cylinder 43 is fixed with a mounting plate 44. A welding torch 5 and a detection seat 6 are fixed on the mounting plate 44.

[0041] In this technical solution, before welding, as Figure 1 shown, there are several groups of flat steel 101, and several groups of flat steel 101 are arranged horizontally at equal intervals. There are two groups of edge wrapping steel 102, and the two groups of edge wrapping steel 102 are respectively arranged on the left and right sides of several groups of flat steel 101, and the two groups of edge wrapping steel 102 only contact the ends of several groups of flat steel 101 before welding; specifically, when welding the flat steel 101 and the edge wrapping steel 102 of the plate 1, first place one end of the flat steel 101 at the baffle 36, and push and clamp the flat steel 101 through the first servo cylinder 37 at the front end to fix it. Then place the edge wrapping steel 102 on both sides of the flat steel 101, and then push the clamping plate 38 through the first servo cylinders 37 on both sides to fix the edge wrapping steel 102 and the flat steel 101, and position it to Figure 1 the state, and then weld the contact position between the edge wrapping steel 102 and the flat steel 101. First, push the side table 3 to slide on the slide rail 39 through the second servo cylinder 40, and push the welding torch 5 to the position where welding is required. Then push the mounting plate 44 to move downward through the third servo cylinder 43, so that the welding torch 5 welds the contact position between one edge wrapping steel 102 and the flat steel 101. After welding is completed, the third servo cylinder 43 resets, and at the same time, the servo motor 42 drives the lead screw 41 to rotate, the lead screw 41 drives the cross plate 4 to move, and the cross plate 4 drives the welding torch 5 to move, and moves the welding torch 5 to the next position where welding is required, and continues the welding work until the welding work is completed;

[0042] When the welding torch 5 welds the next welding position, the detection head 7 moves synchronously with the welding torch 5, and visually inspects the previous weld seam through the detection head 7 to judge whether there are defects in the weld seam. By setting a display 46 on the workbench 2, after the detection head 7 collects the image of the weld seam, it is displayed through the display 46. The 2D + 3D fusion detection technology is adopted, combining three-dimensional point cloud data and two-dimensional images to realize the comprehensive analysis of the weld seam morphology. And the detection head 7 adopts an industrial vision camera, which is a prior art. The detection head 7 in this application only needs to be able to complete the image acquisition of the weld seam, which is not the innovation point of this application and will not be described in detail;

[0043] When the inspection head 7 performs visual inspection, the third servo cylinder 43 drives the mounting plate 44 to move downward. The mounting plate 44 drives the welding torch 5 to move downward, and at the same time drives the inspection seat 6 to move downward. The downward movement of the inspection seat 6 drives the inspection head 7 to move downward. When the inspection seat 6 just starts to move downward, it drives the slide bar 14 to move downward, so that the slide bar 14 slides downward along the chute 15. The slide bar 14 drives the sliding protrusion 16 to slide along the second track groove 17. As Figure 6 shown, when the sliding protrusion 16 slides along the first inclined portion 171, the sliding protrusion 16 drives the slide bar 14 to move to the right. The slide bar 14 drives the round rod 8 to move to the right, so that the round rod 8 slides along the first track groove 12. The sliding of the round rod 8 drives the cylinder 9 to move to the right. The rightward movement of the cylinder 9 drives the cleaning cloth 10 to move to the right, so that the cleaning cloth 10 wipes the lens at the inspection head 7 to remove the soot particle impurities on the lens; when the sliding protrusion 16 slides along the second inclined portion 172, the sliding protrusion 16 drives the slide bar 14 to move leftward to reset, so that the round rod 8, the cylinder 9 and the cleaning cloth 10 move leftward to reset. When resetting, the cleaning cloth 10 wipes the lens of the inspection head 7 to the left. When the cleaning cloth 10 completes the reset, the bottom of the inspection head 7 is flush with the top of the weld. Then the inspection seat 6 continues to move downward, and the sliding protrusion 16 slides downward along the vertical portion 173, and the position of the cleaning cloth 10 remains unchanged. The visual inspection of the weld is carried out through the inspection head 7;

[0044] When the slide bar 14 just starts to move to the right, the slide bar 14 drives the round rod 8 to move to the right. At this time, the round rod 8 slides along the outer moving portion 121 of the first track groove 12. As Figure 5 shown, the round rod 8 moves outward. Through the arranged guide plate 28, guide groove 29 and guide block 30, when the round rod 8 moves, it drives the limit ring 31 to move. The limit ring 31 drives the guide block 30 to slide along the guide groove 29, so as to avoid the situation of jamming when the round rod 8 moves, and at the same time increase the stability of the end of the round rod 8. When the round rod 8 moves outward, it drives the cleaning cloth 10 to move outward, so that the cleaning cloth 10 no longer contacts the surface of the inspection seat 6. When the round rod 8 slides along the inner moving portion 122, the round rod 8 moves inward. The round rod 8 drives the cleaning cloth 10 to move inward, so that the cleaning cloth 10 contacts the surface of the inspection seat 6 again. At this time, the cleaning cloth 10 moves to the leftmost end of the lens of the inspection head 7. Then the round rod 8 slides along the first horizontal portion 123 to wipe the lens of the inspection head 7 with the cleaning cloth 10;

[0045] In order to reduce the occupied space, the cleaning cloth 10 is arranged circumferentially on the cylinder 9. However, as Figure 13As shown in the figure, a columnar structure is adopted. If the wiping point of the cleaning cloth 10 is directly set on the edge of the lens of the detection head 7, the lens of the detection head 7 will be blocked, affecting normal detection. Therefore, one side of the cleaning cloth 10 needs to be set at a position flush with the lens of the detection head 7. At this time, the wiping point of the cleaning cloth 10 will be at a certain distance from the edge of the lens. To prevent the cleaning cloth 10 from wiping the position between this distance, through this technical solution, before the cleaning cloth 10 wipes the lens, by sliding the round rod 8 on the outer moving part 121 and the inner moving part 122, the cleaning cloth 10 can be lifted so that the cleaning cloth 10 does not contact the surface of the detection seat 6, so that before the lens is wiped, the cleaning cloth 10 will not wipe the area outside the lens, and it will only contact the detection seat 6 and the detection head 7 when moving at the lens of the detection head 7;

[0046] In this technical solution, the cleaning cloth 10 adopts an existing spectacle cloth specially used for wiping lenses, such as sheepskin wiping cloth, microfiber wiping cloth, suede wiping cloth, etc. When wiping, it will not scratch the lens.

[0047] Embodiment 2, when the cleaning cloth 10 wipes the lens, it only moves in the left-right direction, resulting in a poor wiping effect on the lens. To solve this problem, this embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 - 13 , the round rod 8 includes a first rod body 801 and a second rod body 802. A connecting column 803 is fixed to the top of the second rod body 802. A limiting block 804 is fixed to the bottom end of the first rod body 801. A limiting groove 805 for the limiting block 804 to slide is opened inside the connecting column 803. A moving component for the cleaning cloth 10 to move up and down reciprocally is arranged between the second rod body 802 and the detection seat 6;

[0048] The moving component includes a circular ring 18 sleeved on the second rod body 802. A telescopic rod 19 is fixed to the surface of the circular ring 18. A third track groove 20 for the telescopic rod 19 to slide is opened on the detection seat 6. The third track groove 20 includes a second horizontal part 201 and a first wave part 202 which are connected in sequence. A limiting strip 21 is fixed to the surface of the detection seat 6. A straight groove 22 is opened on the limiting strip 21. A limiting column 23 is fixed to the telescopic rod 19. The limiting column 23 is slidably arranged in the straight groove 22.

[0049] In this technical solution, when the first rod body 801 slides along the outer moving part 121, the first rod body 801 drives the second rod body 802 to move, the second rod body 802 drives the ring 18 to move, the ring 18 drives the telescopic rod 19 to slide along the second horizontal part 201 of the third track groove 20, and at the same time the ring 18 drives the telescopic rod 19 to extend. When the first rod body 801 slides along the inner moving part 122, the ring 18 drives the telescopic rod 19 to contract. When the first rod body 801 slides along the first horizontal part 123, at this time the cleaning cloth 10 wipes the lens. During the wiping, the second rod body 802 drives the telescopic rod 19 to slide along the first wave part 202, so that the telescopic rod 19 makes a reciprocating up and down movement. The reciprocating up and down movement of the telescopic rod 19 drives the second rod body 802 to make a reciprocating up and down movement. The reciprocating up and down movement of the second rod body 802 drives the cleaning cloth 10 to make a reciprocating up and down movement. Thus, during the process of the cleaning cloth 10 wiping the lens from left to right, it can make a reciprocating up and down movement, thereby further increasing the cleaning effect;

[0050] In this technical solution, through the arranged connecting column 803, limiting block 804 and limiting groove 805, when the second rod body 802 makes a reciprocating up and down movement, the limiting block 804 slides inside the limiting groove 805, so that when the vertical height of the first rod body 801 remains unchanged, the second rod body 802 can make a reciprocating up and down movement, and the limiting block 804 can only slide up and down along the limiting groove 805 and will not rotate relative to the limiting groove 805. Through the arranged limiting strip 21, straight groove 22 and limiting column 23, when the telescopic rod 19 slides along the third track groove 20, the limiting strip 21 slides inside the straight groove 22, so that the end of the telescopic rod 19 can only slide horizontally along the third track groove 20 and will not deviate. The telescopic rod 19 in this application includes an inner rod 191 and an outer rod 192. The inner rod 191 is inserted into the inner part of the outer rod 192, and the inner rod 191 can slide relative to the outer rod 192, so as to realize the telescopic function. The limiting strip 21 is fixed on the inner rod 191, and a bearing 45 is fixed between the ring 18 and the second rod body 802, so that the second rod body 802 can not only move along the moving track of the ring 18, but also can rotate relative to the ring 18.

[0051] Embodiment 3. This embodiment is another technical solution of the moving component. Specifically, please refer to Figures 1 - 13 , the moving component includes a fixed seat 24 fixed on the surface of the detection seat 6. A through groove 25 for the second rod body 802 to slide is opened on the fixed seat 24. A limiting ball 26 is fixed on the circumference of the second rod body 802. A fourth track groove 27 for the limiting ball 26 to slide is opened inside the fixed seat 24. The fourth track groove 27 includes a third horizontal part 271 and a second wave part 272 which are connected in sequence.

[0052] In this technical solution, the trajectory of the through groove 25 is the same as that of the first trajectory groove 12. When the first rod body 801 moves along the first trajectory groove 12, the second rod body 802 moves along the through groove 25. When the second rod body 802 moves along the through groove 25, first, the second rod body 802 drives the limit ball 26 to move, so that the limit ball 26 first slides along the third horizontal part 271. When the cleaning cloth 10 wipes the lens, the limit ball 26 slides along the second wave part 272, enabling the limit ball 26 to perform reciprocating up and down motion. The limit ball 26 drives the second rod body 802 to perform reciprocating up and down motion, and the reciprocating up and down motion of the second rod body 802 drives the cleaning cloth 10 to perform reciprocating up and down motion. Thus, during the process of the cleaning cloth 10 wiping the lens from left to right, it can perform reciprocating up and down motion, further enhancing the cleaning effect.

[0053] Embodiment 4: Since during the process of the cleaning cloth 10 wiping the lens, only one position of the cleaning cloth 10 contacts the lens, during wiping, the cleaning cloth 10 at this position will be quickly contaminated, resulting in a deterioration of the cleaning ability of the cleaning cloth 10 at this place, thereby reducing the cleaning effect on the lens. To address this problem, this embodiment is an improvement based on Embodiment 2 or Embodiment 3. Specifically, please refer to Figures 1 - 13 , a gear 32 is fixed to the end of the first rod body 801, a rack 33 for meshing with the gear 32 is fixed inside the first positioning block 11, and the gear 32 is slidably arranged inside the first positioning block 11;

[0054] A second positioning block 34 is fixed to the surface of the detection seat 6, a fifth trajectory groove 35 is formed in the second positioning block 34, and the round rod 8 passes through the second positioning block 34 and is slidably connected to the fifth trajectory groove 35.

[0055] In this technical solution, when the cleaning cloth 10 moves to the lens, at this time, the first rod body 801 drives the gear 32 to move to mesh with the rack 33. Then, when the cleaning cloth 10 wipes the lens, the first rod body 801 can drive the gear 32 to move along the rack 33, causing the gear 32 to rotate. The rotation of the gear 32 drives the first rod body 801 to rotate, the rotation of the first rod body 801 drives the second rod body 802 to rotate, the rotation of the second rod body 802 drives the cylinder 9 to rotate, and the rotation of the cylinder 9 drives the cleaning cloth 10 to rotate, enabling the cleaning cloth 10 to rotate during the process of wiping the lens. By the rotation of the cleaning cloth 10, the contact surface between the cleaning cloth 10 and the lens is changed, further enhancing the cleaning effect;

[0056] In this technical solution, the trajectories of the fifth track groove 35 and the first track groove 12 are the same. When the first rod body 801 slides along the first track groove 12, the second rod body 802 can slide along the fifth track groove 35, which can increase the stability of the second rod body 802 during movement. Moreover, when the second rod body 802 rotates, it can avoid the situation of the second rod body 802 shaking and prevent the cleaning cloth 10 from separating from the lens.

[0057] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0058] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
