Description

Technical Field

[0001] The invention relates to the technical field of steel grating production, in particular to welding equipment for producing and processing steel gratings. Background Art

[0002] Steel grating is a steel product made of flat steel bars arranged crosswise at a certain spacing and cross bars, and welded into a square grid in the middle. During the production and processing of steel grating, the ends of the flat steel bars are formed longitudinally, and edging steel is welded to make them neat, beautiful, and convenient to use.

[0003] When welding flat steel and edging steel, in order to detect the welding quality, it is necessary to perform visual inspection on the welds between the flat steel and the edging steel. Through visual inspection, it is observed whether the welds meet the requirements. If they are unqualified, rework is required. However, during visual inspection, the lenses on the visual inspection equipment will be contaminated by the smoke particles and impurities generated during welding. During inspection, the attached smoke particles and impurities will block the lenses, thereby hindering image acquisition at the weld and affecting the adequacy and accuracy of weld inspection. 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 slide bar to move downward along the slide groove, so that the slide bar drives the sliding protrusion to slide along the second track groove, so that the sliding protrusion can drive the slide bar to move back and forth left and right once. When the slide bar moves back and forth left and right once, it drives the round rod to move back and forth left and right, and the round rod drives the roller and the cleaning cloth to move back and forth left and right, so that the cleaning cloth can wipe the lens of the detection head, so that before detection, smoke and dust particles attached to the lens of the detection head can be removed to avoid obstruction by smoke and dust particles, thereby improving the adequacy and accuracy of detection. In addition, in the process of the round rod moving left and right, the first track groove is set to make the end of the round rod slide 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 increasing the cleaning effect.

[0018] 2. In the welding equipment for the production and processing of steel gratings, when the cleaning cloth wipes the lens of the detection head left and right, a moving component is set up, and a connecting column is set between the first rod body and the second rod body. The limit block slides inside the limit groove, so that the second rod body and the first rod body can move relative to each other, so that the second rod body can move up and down while moving left and right. The up and down reciprocating movement of the second rod body drives the cleaning cloth to move up and down, so that the cleaning cloth can move up and down while wiping the lens left and right, which is beneficial to improve the wiping effect and further increase the cleaning effect.

[0019] 3. In the welding equipment for the production and processing of steel gratings, when the cleaning cloth wipes the lens of the detection head, the first rod slides along the first track groove. When the first rod slides to the first horizontal part of the first track groove, the gear is engaged with the rack. Then, when the first rod continues to slide along the first horizontal part, it drives the gear to move on the rack, so that the gear drives the first rod to rotate. The rotation of the first rod drives the second rod to rotate. The rotation of the second rod drives the cylinder and the cleaning cloth to rotate, so that the cleaning cloth can rotate when 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, avoiding the problem of only one place of contact between the cleaning cloth and the lens, but also when the cleaning cloth rotates, the granular impurities on the cleaning cloth away from the lens are easy to fall off, thereby further increasing the cleaning effect.

The cleaning cloth 10 slides along the first track groove 12 through the round rod 8 to wipe the detection head 7 left and right;

[0037] The first track groove 12 includes an outward moving portion 121, an inward moving portion 122 and a first horizontal portion 123 which are sequentially connected. A longitudinal plate 13 is fixed to the lower surface of the transverse plate 4. A sliding groove 15 is formed on the longitudinal plate 13. A slide rod 14 is slidably arranged in the sliding groove 15. A guide plate 28 is fixed to the end of the slide rod 14. A guide groove 29 is formed on the guide plate 28.

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

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

[0040] A screw rod 41 is rotatably provided at the top of the side platform 3, and a servo motor 42 which is transmission-connected to the screw rod 41 is fixed on the surface of the side platform 3. The end of the horizontal plate 4 is threadedly connected to the screw rod 41, and a third servo electric cylinder 43 is fixed on the lower surface of the horizontal plate 4. The output end of the third servo electric cylinder 43 is fixed with a mounting plate 44, and the welding gun 5 and the detection seat 6 are fixed on the mounting plate 44.

[0041] In this technical solution, before welding, Figure 1 As shown, several groups of flat steel 101 are provided, and several groups of flat steel 101 are arranged horizontally at equal intervals, and two groups of edging steel 102 are provided, and the two groups of edging steel 102 are respectively arranged on the left and right sides of the several groups of flat steel 101, and the two groups of edging steel 102 only contact the end parts of the several groups of flat steel 101 before welding; specifically, when welding the flat steel 101 and the edging steel 102 of the plate 1, first, one end of the flat steel 101 is placed on the baffle 36, and the flat steel 101 is fixed by pushing and clamping with the first servo electric cylinder 37 at the front end, and then the edging steel 102 is placed on both sides of the flat steel 101, and then the first servo electric cylinders 37 on both sides push the clamping plate 38 to fix the edging steel 102 and the flat steel 101, and position them to Figure 1 state, and then weld the contact position of the cladding steel 102 and the flat steel 101. First, the second servo electric cylinder 40 pushes the side table 3 to slide on the slide rail 39, and pushes the welding gun 5 to the position where welding is required. Then, the third servo electric cylinder 43 pushes the mounting plate 44 downward to make the welding gun 5 weld the contact position of the cladding steel 102 and the flat steel 101. After welding is completed, the third servo electric cylinder 43 is reset, and at the same time, the servo motor 42 drives the screw rod 41 to rotate the screw rod 41 to drive the cross plate 4 to move, and the cross plate 4 drives the welding gun 5 to move, and the welding gun 5 is moved to the next position where welding is required, and the welding work is continued until the welding work is completed.

[0042] When the welding gun 5 is welding the next welding position, the detection head 7 moves synchronously with the welding gun 5, and the detection head 7 performs visual inspection on the previous weld to determine whether the weld has defects. By setting a display 46 on the workbench 2, after the detection head 7 collects the image of the weld, it is displayed on the display 46. The 2D+3D fusion detection technology is used to combine the three-dimensional point cloud data and the two-dimensional image to achieve a comprehensive analysis of the weld morphology. The detection head 7 uses an industrial visual 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. It is not an innovation of this application and will not be described in detail.

[0043] When the detection head 7 performs visual inspection, the third servo electric cylinder 43 drives the mounting plate 44 to move downward, the mounting plate 44 drives the welding gun 5 to move downward, and at the same time drives the detection seat 6 to move downward, the detection seat 6 moves downward and drives the detection head 7 to move downward, when the detection seat 6 just moves downward, it drives the slide bar 14 to move downward, so that the slide bar 14 slides downward along the slide groove 15, and the slide bar 14 drives the sliding protrusion 16 to slide along the second track groove 17, as shown in FIG. Figure 6 As shown, when the sliding protrusion 16 slides along the first inclined portion 171, the sliding protrusion 16 drives the sliding rod 14 to move to the right, and the sliding rod 14 drives the round rod 8 to move to the right, so that the round rod 8 slides along the first track groove 12, and the round rod 8 slides and drives the cylinder 9 to move to the right, and the cylinder 9 moves to the right and drives the cleaning cloth 10 to move to the right, so that the cleaning cloth 10 wipes the lens at the detection head 7 to remove the smoke particles and impurities on the lens; when the sliding protrusion 16 slides along the second inclined portion 172, the sliding protrusion 16 drives the sliding rod 14 to move to the left and reset, so that the round rod 8, the cylinder 9 and the cleaning cloth 10 move to the left and reset, and when resetting, the cleaning cloth 10 wipes the lens of the detection head 7 to the left, and when the cleaning cloth 10 is reset, the bottom of the detection head 7 is flush with the top of the weld, and then the detection seat 6 continues to move downward, and the sliding protrusion 16 slides downward along the vertical portion 173, the position of the cleaning cloth 10 remains unchanged, and the weld is visually inspected by the detection head 7;

[0044] When the slide bar 14 just moves to the right, the slide bar 14 drives the round bar 8 to move to the right. At this time, the round bar 8 slides along the outward moving portion 121 of the first track groove 12. Figure 5 As shown, the round rod 8 moves outward, and through the provided guide plate 28, guide groove 29 and guide block 30, when the round rod 8 moves, the limit ring 31 is driven to move, and the limit ring 31 drives the guide block 30 to slide along the guide groove 29, thereby avoiding the round rod 8 from getting stuck during movement, and at the same time increasing 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 detection seat 6. When the round rod 8 slides along the inward moving portion 122, the round rod 8 moves inward, and the round rod 8 drives the cleaning cloth 10 to move inward, so that the cleaning cloth 10 contacts the surface of the detection seat 6 again. At this time, the cleaning cloth 10 moves to the leftmost end of the lens of the detection head 7, and then the round rod 8 slides along the first horizontal portion 123, so that the cleaning cloth 10 wipes the lens of the detection head 7;

[0045] In order to reduce the occupied space, the cleaning cloth 10 is arranged on the cylinder 9 in a circular manner, but as shown in FIG. Figure 13As shown, 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 maintain a certain distance from the edge of the lens. In order to prevent the cleaning cloth 10 from wiping the position between this distance, through the present technical solution, before the cleaning cloth 10 wipes the lens, the round rod 8 slides on the outward moving part 121 and the inward moving part 122 to lift the cleaning cloth 10 so that the cleaning cloth 10 does not contact the surface of the detection seat 6, so that before wiping the lens, the cleaning cloth 10 will not wipe the area outside the lens, and will only contact the detection seat 6 and the detection head 7 when it moves at the lens of the detection head 7;

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

[0047] In the second embodiment, when the cleaning cloth 10 is wiping the lens, it only moves in the left and right directions, which makes the wiping effect of the lens poor. To solve this problem, this embodiment is an improvement made on the basis of the first embodiment. For details, 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 is provided inside the connecting column 803 for the limiting block 804 to slide. A moving component for the cleaning cloth 10 to reciprocate up and down is provided between the second rod body 802 and the detection seat 6.

[0048] The moving assembly includes a ring 18 that is sleeved on the second rod body 802, and a telescopic rod 19 is fixed to the surface of the ring 18. A third track groove 20 for the telescopic rod 19 to slide is provided on the detection seat 6. The third track groove 20 includes a second horizontal portion 201 and a first wavy portion 202 that are connected in sequence. A limit strip 21 is fixed to the surface of the detection seat 6, and a straight groove 22 is provided on the limit strip 21. A limit column 23 is fixed on the telescopic rod 19, and the limit column 23 is slidably set in the straight groove 22.

[0049] In the present technical solution, when the first rod 801 slides along the outward moving portion 121, the first rod 801 drives the second rod 802 to move, and the second rod 802 drives the ring 18 to move, and the ring 18 drives the telescopic rod 19 to slide along the second horizontal portion 201 of the third track groove 20. At the same time, the ring 18 drives the telescopic rod 19 to extend. When the first rod 801 slides along the inward moving portion 122, the ring 18 drives the telescopic rod 19 to retract. When the first rod 801 slides along the first horizontal portion 123, the cleaning cloth 10 wipes the lens. During wiping, the second rod 802 drives the telescopic rod 19 to slide along the first wavy portion 202, so that the telescopic rod 19 performs an up and down reciprocating motion. The up and down reciprocating motion of the telescopic rod 19 drives the second rod 802 to perform an up and down reciprocating motion. The up and down reciprocating motion of the second rod 802 drives the cleaning cloth 10 to perform an up and down reciprocating motion. Therefore, the cleaning cloth 10 can perform an up and down reciprocating motion while wiping the lens left and right, thereby further improving the cleaning effect.

[0050] In the present technical solution, by providing the connecting column 803, the limiting block 804 and the limiting groove 805, when the second rod body 802 performs the up-and-down reciprocating motion, 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 perform the up-and-down reciprocating motion, 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. By providing the limiting strip 21, the straight groove 22 and the limiting column 23, when the telescopic rod 19 slides along the third track groove 20, the limiting strip 21 is in the straight groove. 22 slides inside, so that the end of the telescopic rod 19 can only slide horizontally along the third track groove 20 without deviation; the telescopic rod 19 in the present 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, thereby realizing the telescopic function, the limit 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 the second rod body 802 can rotate relative to the ring 18.

[0051] Example 3: This example is another technical solution for moving components. For details, please refer to Figures 1-13 The moving assembly includes a fixed seat 24 fixed on the surface of the detection seat 6, and a through groove 25 is provided on the fixed seat 24 for the second rod body 802 to slide. A limiting ball 26 is fixed on the circumference of the second rod body 802, and a fourth track groove 27 is provided inside the fixed seat 24 for the limiting ball 26 to slide. The fourth track groove 27 includes a third horizontal portion 271 and a second wave portion 272 that are connected in sequence.

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

[0053] In the fourth embodiment, since only one position of the cleaning cloth 10 contacts the lens during wiping, the cleaning cloth 10 at that position will be quickly contaminated, resulting in a decrease in the cleaning ability of the cleaning cloth 10 at that position, thereby reducing the cleaning effect of the lens. To address this problem, this embodiment is an improvement made on the basis of the second or third embodiment. For details, please refer to Figures 1-13 A gear 32 is fixed to the end of the first rod 801, a rack 33 for meshing with the gear 32 is fixed inside the first positioning block 11, and the gear 32 is slidably disposed in the first positioning block 11;

[0054] A second positioning block 34 is fixed on the surface of the detection base 6 . A fifth track groove 35 is formed on the second positioning block 34 . The round rod 8 passes through the second positioning block 34 and is slidably connected to the fifth track groove 35 .

[0055] In the present technical solution, when the cleaning cloth 10 moves to the lens, the first rod 801 drives the gear 32 to move and engage with the rack 33. Then, when the cleaning cloth 10 wipes the lens, the first rod 801 can drive the gear 32 to move along the rack 33, so that the gear 32 rotates. The rotation of the gear 32 drives the first rod 801 to rotate. The rotation of the first rod 801 drives the second rod 802 to rotate. The rotation of the second rod 802 drives the cylinder 9 to rotate. The rotation of the cylinder 9 drives the cleaning cloth 10 to rotate, so that the cleaning cloth 10 can rotate when wiping the lens. The rotation of the cleaning cloth 10 changes the contact surface between the cleaning cloth 10 and the lens, thereby further improving the cleaning effect.

[0056] In the present technical solution, the fifth track groove 35 and the first track groove 12 have the same track, so that when the first rod 801 slides along the first track groove 12, the second rod 802 can slide along the fifth track groove 35, which can increase the stability of the second rod 802 when it moves, and when the second rod 802 rotates, it can prevent the second rod 802 from shaking, thereby preventing the cleaning cloth 10 from separating from the lens.

[0057] It should be noted that, in this document, relational terms such as first and second, etc., are used only 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 terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
