Description

TECHNICAL FIELD

[0001] The present application belongs to the field of silicon steel detection, and particularly relates to a silicon steel welding seam quality detection equipment. BACKGROUND

[0002] Electrical steel, also known as silicon steel sheet, is an important soft magnetic alloy indispensable for the power, electronic and military industries, and is also the largest metal functional material, and is mainly used as the core of various motors, generators and transformers. In the production line of silicon steel sheets, the silicon steel sheets are continuously annealed, and after annealing, the silicon steel sheets are extruded and welded, and the welded silicon steel sheets are extruded into a steel strip by a plurality of rollers. After the steel strip is extruded and thinned, the tension received by the steel strip needs to be maintained to ensure the required tension and flexibility of the steel strip during use.

[0003] After the silicon steel sheet is extruded into a steel strip after annealing, the extruded steel strip is connected by welding. After connection, the steel strip is collected in a roll. When collected in a roll, the welded interface will be bent into an arc, and the steel strip will be extruded and stretched and transported by rollers. If the welding quality of the interface is poor, the conditions of incomplete penetration, incomplete penetration, inclined welding and deviation occur. When the steel strip is bent under tension, the phenomenon of broken strip will occur. When the strip is broken, the tension of the steel strip will be released, which may cause the rollers and the machine to be damaged by the steel strip. Therefore, the welding seam of the silicon steel sheet needs to be detected before being collected in a roll.

[0004] After the silicon steel sheet is annealed and welded, the silicon steel sheet is usually photographed by a camera before being collected in a roll. The photographed photos are compared and observed to determine whether the silicon steel sheet has the problems of incomplete penetration and incomplete penetration. If the welding position is defective, the phenomenon of broken strip will occur when it is bent, which will cause an accident. When the welding position is defective, the welding seam needs to be cut by stopping the machine. At this time, the front end of the steel strip cannot continuously maintain the tension and extrusion effect, which affects the quality of the silicon steel product.

[0005] Therefore, the present application provides a silicon steel welding seam quality detection equipment. SUMMARY

DETAILED DESCRIPTION

[0037] Embodiment one

[0038] As Figures 1-7As shown, the welding quality detection equipment for silicon steel strip of the embodiment of the application comprises a first detection top plate 1, a first bottom plate 11 and a second cutting bottom plate 31, a plurality of second rotating blocks 15 are fixedly installed at the bottom end of the first detection top plate 1, first top rollers 151 are rollingly connected in the second rotating blocks 15, a second camera 141 is fixedly installed at the center bottom end of the first detection top plate 1, two first supporting blocks 12 are fixedly installed at the bottom end of the first bottom plate 11, a plurality of first rotating blocks 13 are fixedly installed at the top end of the first bottom plate 11, first rollers 131 are rollingly installed in the first rotating blocks 13, a first camera 14 is fixedly installed at the center top end of the first bottom plate 11, a lifting device 2 is arranged at the end of the first detection top plate 1, the lifting device 2 is used for lifting and lowering the workpiece, a cutting table 3 is arranged at the other end of the lifting device 2, and the cutting table 3 is used for cutting the workpiece in the lifting device 2.

[0039] Specifically, first, two steel strips after continuous annealing of silicon steel sheets are end-to-end welded, then the steel strips are transported to the first rollers 131, so that the steel strips are located between the first rollers 131 and the first top rollers 151, the first rollers 131 and the first top rollers 151 extrude and transport the steel strips of the silicon steel sheets and keep the steel strips under the tension of the first rollers 131 and the first top rollers 151 at the bottom end of the first detection top plate 1, the silicon steel sheets pass through the middle positions of the first camera 14 and the second camera 141, the first camera 14 and the second camera 141 are used for detecting and observing the welds of the silicon steel sheets, when the first camera 14 and the second camera 141 detect that the silicon steel sheets are qualified, the plurality of first rollers 131 and the first top rollers 151 continue to transport until the steel strips are transported to the inside of the lifting device 2, then enter the inside of the cutting table 3 after passing through the lifting device 2, and then enter the next procedure to collect the extruded steel strips into a roll, if the first camera 14 and the second camera 141 detect that the welds of the steel strips have defects, the cutting table 3 can cut the welds detected by the first camera 14 and the second camera 141, at this time, the steel strips stop being transported in the cutting table 3, the lifting device 2 is lifted upward by the first rollers 131, and the steel strips at the rear end of the lifting device 2 are subjected to weld cutting treatment without stopping, so as to ensure that the steel strips at the front end of the lifting device 2 are continuously transported to keep the extrusion effect and prevent the steel strips from being deflected, when the first rollers 131 continuously transport the silicon steel sheets, the tension and flexibility of the front-end steel strips are maintained, and the quality of the front-end steel strips is maintained during cutting treatment.

[0040] As Figures 3-4As shown, the lifting device 2 includes a first lifting limiting block 212 fixedly installed at the bottom end of the first lifting plate 21. A first lifting roller 211 is rolled inside the first lifting limiting block 212. A second lifting plate 23 is provided at the lower end of the first lifting plate 21. A bottom limiting block 22 is slidably installed at the bottom end of the second lifting plate 23. A plurality of second lifting limiting blocks 233 are fixedly installed at the top end of the second lifting plate 23. A second lifting roller 232 is rolled inside the second lifting limiting block 233. A lifting protrusion 231 is fixedly installed at the bottom end of the second lifting plate 23. A bottom limiting groove 221 is provided inside the bottom limiting block 22.

[0041] Specifically, if the first camera 14 and the second camera 141 detect a problem with the silicon steel weld, the first roller 131 at the front end of the lifting device 2 operates normally, while the cutting table 3 stops operating. Therefore, the lifting device 2 needs to be lifted to prevent the silicon steel sheet from folding between the lifting device 2 and the cutting table 3. The cutting table 3 includes a second cutting base plate 31 installed at the end of the second lifting plate 23. Multiple third rotating blocks 33 are fixedly installed on the top of the second cutting base plate 31. Third rollers 332 are rolled inside the third rotating blocks 33. Weldings that have not passed the third rollers 332... The completed steel strip is the front end of the steel strip, and the part that passes through the third roller 332 is the rear end of the steel strip. The first lifting roller 211 and the second lifting roller 232 of the lifting device will rotate under the power of the first roller 131 at the front end. The lifting protrusion 231 can be raised first. The lifting protrusion 231 drives the second lifting plate 23 and the first lifting plate 21 at the top to rise upward. When the silicon steel sheet is cut inside the cutting table 3, the silicon steel sheet is stopped from being transported inside the cutting table 3. Because the transport speed of the front end and the rear end of the steel strip is different, the silicon steel sheet is prevented from folding on both sides of the first lifting plate 21.

[0042] like Figures 7-8 As shown, the cutting table 3 includes a second cutting base plate 31 installed at the end of the lifting device 2. A plurality of third rotating blocks 33 are fixedly installed at the top of the second cutting base plate 31. A third roller 332 is rolled inside the third rotating block 33. A cutting device 4 is provided at the center top of the second cutting base plate 31. Two second support blocks 32 are fixedly installed at the bottom of the second cutting base plate 31. A second cutting top plate 311 is provided at the upper end of the second cutting base plate 31. A third support block 312 is fixedly installed at the bottom end of the second cutting top plate 311. A fourth roller 313 is rolled inside the third support block 312. Anti-slip devices 5 are provided at the bottom end of the third roller 332 and the top end of the fourth roller 313 near the end of the lifting device 2 to prevent the third roller 332 from rotating.

[0043] Specifically, when the first camera 14 and the second camera 141 detect the silicon steel sheet with a welding defect, information is transmitted to the cutting table 3. When the welding seam of the silicon steel sheet moves to the upper end of the cutting device 4, the plurality of third rollers 332 are stopped, the cutting device 4 cuts off the unqualified silicon steel welding seam, and after cutting off, the next process is carried out. The anti-skid device 5 can lock the third roller 332 to prevent the third roller 332 from rotating due to pulling of the silicon steel sheet at the front end or the rear end during cutting, thereby improving the accuracy and safety of cutting.

[0044] As shown in Figure 8 , the cutting device 4 comprises a first hydraulic column 41 fixedly installed at the top end of the second cutting base plate 31. The top end of the first hydraulic column 41 is fixedly installed with a cutting slide plate 42. The top end of the cutting slide plate 42 is rollingly installed with a threaded cutting column 43. The outer wall of the threaded cutting column 43 is threadedly connected with a cutting sliding block 44. The inside of the cutting sliding block 44 is rollingly installed with a cutting blade 46. The end of the cutting blade 46 is fixedly installed with a motor 45. The outer wall of the motor 45 is fixedly installed at the top end of the cutting sliding block 44.

[0045] Specifically, when the welding seam of the silicon steel sheet enters the angle corresponding to the cutting blade 46, the first hydraulic column 41 is started to lift the cutting slide plate 42 upward, so as to approach the silicon steel sheet. The cutting blade 46 at the top end of the cutting slide plate 42 can cut and polish the welding seam of the silicon steel sheet, thereby facilitating reprocessing or use of the silicon steel sheet.

[0046] As shown in Figure 7 , the anti-skid device 5 comprises a second hydraulic column 51 fixedly installed at the center top end of the second cutting base plate 31. The top end of the second hydraulic column 51 is fixedly installed with a stopping piece 52.

[0047] Specifically, when the cutting table 3 stops conveying the silicon steel sheet, the second hydraulic column 51 is opened. The end of the second hydraulic column 51 is provided with the stopping piece 52 abutting against the third roller 332. When the third roller 332 stops rotating, the second hydraulic column 51 is tightly abutted against the third roller 332 through friction force. The lifting device 2 will cause the silicon steel sheet to pull the third roller 332 when lifting. The stopping piece 52 of the cutting device 4 can prevent the third roller 332 from being pulled during cutting of the silicon steel sheet.

[0048] As shown in Figure 6 , the side wall of the first lifting plate 21 and the second lifting plate 23 is fixedly installed with a lifting side plate 24. The side wall of the lifting side plate 24 is fixedly installed with a lifting side plate fixing block 241. The inside of the lifting side plate fixing block 241 is rollingly installed with a lifting threaded rod 242. The outer wall of the lifting threaded rod 242 is slidingly installed with a lifting gear 243. The outer wall of the lifting gear 243 is provided with a transmission device 6 for lifting the lifting device 2.

[0049] Specifically, when the first camera 14 and the second camera 141 detect that the silicon steel sheet welding site needs to be re-cut and adjusted, the third roller 332 inside the cutting table 3 needs to be stopped rotating, in order to prevent the silicon steel sheet from being folded, the lifting threaded rod 242 is rotated by the rotating lifting gear 243, and the lifting side plate 24 is moved up and down under the action of the lifting gear 243, thereby completing the lifting of the lifting device 2 as a whole.

[0050] As shown in Figure 2 , Figure 5 and Figure 6 , the second roller 1322 is installed inside the first rotating block 13 near one end of the lifting device 2, the first roller protruding column 1321 is fixedly installed at the end of the second roller 1322, the transmission device 6 includes an extension limiting block 611 fixedly installed on the second cutting bottom plate 31 and the side wall of the first rotating block 13, the first bevel gear 132 is fixedly installed on the outer wall of the first roller protruding column 1321, the second roller protruding column 3321 is fixedly installed on the side wall of the third roller 332, the first power column 62 is installed inside the extension limiting block 611 of the side wall of the first rotating block 13, the second power column 63 is installed inside the extension limiting block 611 of the side wall of the second cutting bottom plate 31, the driven gear ring 64 is installed at the end of the first power column 62 and the second power column 63, the fixed protrusion 61 is fixedly installed at the top end of the extension limiting block 611, the lifting gear limiting ring 2431 is fixedly installed on the side wall of the fixed protrusion 61, the lifting gear 243 is rotatably installed at the top end of the lifting gear limiting ring 2431, the second driven column 65 is rotatably installed inside the fixed protrusion 61, the fifth power bevel gear 651 is fixedly installed at the bottom end of the second driven column 65, the sixth power bevel gear 652 is fixedly installed at the top end of the second driven column 65, the outer wall of the sixth power bevel gear 652 is engaged with the lifting gear 243, the driven side bevel gear 643 is provided on the side wall of the driven gear ring 64, and the driven gear ring 64 is engaged with the fifth power bevel gear 651 through the driven side bevel gear 643.

[0051] Specifically, when cutting the weld of silicon steel, the plurality of third rollers 332 inside the cutting table 3 stop rotating, while the first roller 131 and the second roller 1322 continue to rotate, and the lifting device 2 is not easily lifted according to the conveying speed of the first roller 131 and the second roller 1322. The driven gear ring 64 can be rotated by the different rotating speeds of the first roller protruding column 1321 and the second roller protruding column 3321. If the rotating speeds of the first roller protruding column 1321 and the second roller protruding column 3321 are the same, the driven gear ring 64 does not rotate. If they are different, the driven gear ring 64 can be rotated. The first roller protruding column 1321 and the second roller protruding column 3321 mesh with the first power helical gear 621 and the third power helical gear 631 to drive the driven gear ring 64 to rotate. The driven gear ring 64 drives the fifth power helical gear 651 connected to the outer wall gear to rotate. The fifth power helical gear 651 drives the second driven column 65 and the sixth power helical gear 652 to rotate. The sixth power helical gear 652 meshes with the lifting gear 243 to drive the lifting of the lifting side plate 24 and the lowering, so that the lifting device 2 is lifted and lowered by the rotating speeds of the first roller protruding column 1321 and the third roller 332.

[0052] As shown in Figure 2 and Figure 6 , a plurality of driven inner cylinders 641 are rollingly installed inside the driven gear ring 64. The end of the driven inner cylinder 641 is fixedly installed with a driven inner helical gear 642. One end of the first power column 62 is fixedly installed with a first power helical gear 621. The other end of the first power column 62 is fixedly installed with a second power helical gear 622. One end of the second power column 63 is fixedly installed with a third power helical gear 631. The other end of the second power column 63 is fixedly installed with a fourth power helical gear 632. The outer wall of the fourth power helical gear 632 and the plurality of driven inner helical gears 642 mesh with the second power helical gear 622. The first power helical gear 621 meshes with the first roller protruding column 1321. The third power helical gear 631 meshes with the second roller protruding column 3321.

[0053] Specifically, when the first roller convex column 1321 and the second roller convex column 3321 drive the first power column 62 and the second power column 63 to rotate, the second power bevel gear 622 and the fourth power bevel gear 632 mesh with the plurality of driven inner bevel gears 642 inside the driven gear ring 64, the side wall of the driven gear ring 64 is provided with a driven side bevel gear 643, the driven side bevel gear 643 meshes with the fifth power bevel gear 651, the fifth power bevel gear 651 drives the sixth power bevel gear 652 to rotate, thereby driving the lifting gear 243 to rotate, if the first power column 62 rotates and the second power column 63 stops rotating, the second power bevel gear 622 meshes with the driven inner bevel gear 642, the driven inner bevel gear 642 rotates with the driven inner cylindrical column 641 at the same time, and under the action of the driven gear ring 64, it makes a circular rotating motion, thereby driving the driven gear ring 64 to rotate, driving the lifting device 2 to rise, if the first power column 62 does not rotate and the second power column 63 rotates, it can drive the lifting device 2 to descend, if the second power column 63 and the first power column 62 have the same rotating speed, the driven inner cylindrical column 641 and the driven inner bevel gear 642 rotate inside the driven gear ring 64, while the driven gear ring 64 does not rotate, this device can determine the lifting and lowering of the lifting side plate 24 through the rotating speed of the second roller convex column 3321.

[0054] As shown in Figure 1 , the height of the first detection top plate 1 and the second cutting top plate 311 is flush, and the height of the second cutting bottom plate 31 and the first bottom plate 11 is flush.

[0055] Specifically, the top end of the first detection top plate 1 and the second cutting top plate 311 is connected to the upper end of the fixing device, and the height of the first detection top plate 1 and the second cutting top plate 311 and the second cutting bottom plate 31 and the first bottom plate 11 is flush, preventing the silicon steel plate from falling out when the silicon steel plate is transported and cut.

[0056] As shown in Figures 1-2 , the distance between the first camera 14 and the second camera 141 exceeds the distance between the first roller 131 and the first top roller 151.

[0057] Specifically, the first camera 14 and the second camera 141 pass through the silicon steel plate in the middle, and the distance between the first camera 14 and the second camera 141 is greater than the distance between the first roller 131 and the first top roller 151, which can facilitate the smooth passage of the silicon steel plate through the first camera 14 and the second camera 141 without touching the silicon steel plate, if the first camera 14 and the second camera 141 detect that the silicon steel weld has a problem.

[0058] Working principle: first, the silicon steel sheet after continuous annealing steel strip is transported to the first roller 131, when the steel strip enters the first roller 131, the first roller 131 and the first top roller 151 are extruded to transport the steel strip of the silicon steel sheet and keep the tension of the steel strip, the silicon steel sheet passes through the middle position of the first camera 14 and the second camera 141, the first camera 14 and the second camera 141 are used for detecting and observing the weld of the silicon steel sheet, when the first camera 14 and the second camera 141 detect that the silicon steel sheet is qualified, a plurality of first rollers 131 and first top rollers 151 continue to transport until the steel strip is transported to the inside of the lifting device 2, after passing through the lifting device 2, it enters the inside of the cutting table 3, and then enters the next procedure to collect the extruded steel strip into a roll, if the first camera 14 and the second camera 141 detect that the weld of the silicon steel sheet has defects, the information is transmitted to the lifting device 2 and the cutting table 3, so that when the weld of the silicon steel sheet moves to the upper end of the cutting device 4, the third roller 332 stops, the second hydraulic column 51 is opened, the end of the second hydraulic column 51 is provided with a stop piece 52 which is in close contact with the third roller 332, when the third roller 332 stops rotating, the second hydraulic column 51 is in close contact with the third roller 332 through friction force, preventing the third roller 332 from rotating, when the weld of the silicon steel sheet enters the angle corresponding to the cutting piece 46, the first hydraulic column 41 can be started to lift the cutting slide plate 42 upward, so as to approach the silicon steel sheet, the cutting piece 46 at the top end of the cutting slide plate 42 can cut and polish the weld of the silicon steel sheet, at the same time, the first roller protruding column 1321 drives the driven gear ring 64 to rotate, the driven gear ring 64 drives the fifth power helical gear 651 connected with the outer wall gear to rotate, the fifth power helical gear 651 drives the second driven column 65 and the sixth power helical gear 652 to rotate, and the sixth power helical gear 652 is engaged with the lifting gear 243, driving the lifting side plate 24 to rise, after the cutting and polishing of the weld of the silicon steel sheet are completed, the second roller protrusion 3321 is rotated, and the rotation speed of the second roller protrusion 3321 is increased, then the rotation speed of the second power column 63 is faster, which can drive the driven gear ring 64 to rotate in the opposite direction, thereby driving the lifting side plate 24 to move downward until the second lifting plate 23 operates to the same height as the first rotating block 13 and the second cutting bottom plate 31, the rotation speed of the second roller protrusion 3321 and the rotation speed of the first roller protruding column 1321 are adjusted to the same speed, and the work can continue.
