Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to a cold-rolled galvanized steel coil ridge defect detection device. Background Art

[0002] Galvanized products have been widely used in home appliances, automobiles and other fields. Home appliance and automobile factory users have extremely strict requirements for color coating. Once the cold-rolled galvanized steel coil has bulge defects, corrugated plates will appear when the coil is unrolled at the client's end, which will cause serious losses to the client's continuous production line. Although severe bulges are not easy to flow out, slight bulge defects are not easy to be detected by human eyes, but there will be slight waves when unrolling. Once the defects are shipped out of the factory, it will affect subsequent production. At present, the detection of steel coil bulge defects is entirely through the inspection personnel's observation of the appearance of the steel coil off the line. It is greatly affected by the on-site light and personal recognition, and it is impossible to form a specific judgment standard, which has an adverse effect on the subsequent hot rolling end analysis and solution of the bulge problem.

[0033] In this embodiment, the detection component 2 also includes a connecting frame 25, the outermost end of the movable frame 21 is fixed with the connecting frame 25, and the bottom of the connecting frame 25 is rotatably installed with a socket 28 through a bearing, the connecting shaft 39 is fixed with an arc block 315 at the position corresponding to the socket 28, and the arc block 315 is slidably inserted into the socket 28, the arc block 315 has the same rotation path as the driving column 1, the outer end of the connecting frame 25 located at the socket 28 is fixed with a driving motor 27, and the output end of the driving motor 27 is fixedly connected to the connecting shaft 39, in the process of the installation component 3 and the steel coil body 4 rotating to the bottom of the detection component 2, the arc block 315 is inserted into the socket 28, thereby completing the transmission connection between the driving motor 27 and the connecting shaft 39, driven by the driving motor 27, the contact between the disc 35 and the extrusion plate 311 on the two ends and the inner wall of the steel coil body 4 will drive the steel coil body 4 to rotate together, thereby cooperating with the detection component 2 for comprehensive detection.

[0034] In this embodiment, the movable frame 21 has a screw 22 rotatably mounted inside through a bearing, the slide seat 24 is threadedly sleeved on the surface of the screw 22, the plug plate 210 is slidably plugged into the bottom of the slide seat 24, the movable frame 21 has an outer plate 26 fixed to the back side corresponding to the infrared emitter 29, the top of the vertical plate 38 is slidably plugged into the bottom of the outer plate 26, the movable frame 21 has a screw 22 rotatably mounted inside through a bearing, the slide seat 24 is threadedly sleeved on the surface of the screw 22, The plug plate 210 is slidably plugged into the bottom of the slide seat 24, the outer plate 26 is fixed to the back of the mobile frame 21 corresponding to the infrared emitter 29, the top of the vertical plate 38 is slidably plugged into the bottom of the outer plate 26, a first spring 213 is fixed between the top of the ball 212 and the slide seat 24, the side of the mobile frame 21 and the surface of the plug plate 210 are both installed with a displacement sensor and a scale plate 23, the screw 22 is driven by the motor inside the mobile frame 21, and the ball 212 and the steel coil are connected.

At this time, the infrared transmitter 29 and the receiver 211 are misaligned. The electrical signal is transmitted to the control end, and the current position is marked by the displacement sensor, and the horizontal and vertical lengths of the raised are recorded. Because the outer plate 26 is connected to the vertical plate 38, when the position of the infrared transmitter 29 is adjusted, the position of the outer end disk 35 of the steel coil body 4 will also be adjusted synchronously, so that the two disks 35 clamp the steel coil body 4.

[0035] In this embodiment, a moving groove 13 is opened inside the driving column 1, and a moving block 15 is rotatably installed at the position of the moving groove 13 by the connecting shafts 39 of the two groups of the mounting assemblies 3, and the moving block 15 slides along the two sides of the moving groove 13.

The third gear 111 is fixedly sleeved on the bottom surface of the driving column 1. The driving column 1 is driven by its own motor, which is not shown in the figure. When the moving column 1 rotates, because the top frame 11 is connected to the rotation of the driving column 1, the top frame 11 and the detection component 2 do not rotate. The positions of the two groups of mounting components 3 and the steel coil body 4 are exchanged separately. During the replacement process, the rotation of the driving column 1 will drive the third gear 111 to rotate and mesh with the second gear 110, and the transmission rod 19 drives the first bevel gear 17 to mesh and rotate with the second bevel gear 18, thereby driving the first gear 14 to rotate. The gears on both sides mesh with the first gear 14 and move in opposite directions, driving the moving block 15 to slide along the moving groove 13, and the heights of the two groups of mounting components 3 are adjusted. The mounting component 3 and the steel coil body 4 close to the detection component 2 side move upward until they contact the detection component 2, away from the top of the driving column 1 and close to the ground.

The installation position is close to the ground, which is convenient for disassembly and installation, and at the same time reduces the gravity borne by the mounting component 3.

[0036] When using the device, install the steel coil body 4 on the installation component 3 and rotate it to the bottom of the detection component 2. Through the linear movement of the detection component 2 and the rotation of the steel coil body 4 itself, the entire outer surface of the steel coil body 4 is comprehensively detected. At the same time, another set of installation components 3 can be installed with another set of steel coil bodies 4. After the detection of the previous set of steel coil bodies 4 is completed, the positions of the two sets of installation components 3 and the steel coil bodies 4 are replaced by the driving column 1, so as to continue to complete the detection work. When the driving column 1 rotates, because the top frame 11 is connected to the rotation of the driving column 1, the top frame 11 and the detection component 2 do not rotate, and the positions of the two sets of installation components 3 and the steel coil bodies 4 are replaced separately. In the replacement process, the rotation of the driving column 1 The movement will drive the third gear 111 to rotate and mesh with the second gear 110, and the transmission rod 19 drives the first bevel gear 17 to mesh with the second bevel gear 18 to rotate, thereby driving the first gear 14 to rotate, and the gears on both sides mesh with the first gear 14 and move in opposite directions, driving the moving block 15 to slide along the moving groove 13, and adjusting the height of the two sets of mounting components 3, the mounting component 3 and the steel coil body 4 close to the detection component 2 side move upward until they contact the detection component 2, away from the top of the driving column 1 and close to the ground. At this time, it is convenient to manually remove the steel coil body 4 on the mounting component 3 or install a new steel coil body 4 again. The installation position is close to the ground, which is convenient for disassembly and installation, and at the same time reduces the load borne by the mounting component 3 The ball 212 is subjected to gravity. When the ball 212 contacts the surface of the steel coil body 4, the rotation of the screw 22 drives the slide seat 24 to slide along the moving seat, so that the ball 212 slides along the surface of the steel coil body 4. The first electric push rod 12 drives the moving frame 21 to slide along the top frame 11, and the position of the infrared transmitter 29 is adjusted to be located at the outer edge of the steel coil body 4. Through the cooperation of the infrared transmitter 29 and the receiver 211, when the two correspond, it means that the steel coil body 4 is flat. When encountering a raised position, the ball 212 will squeeze the first spring 213, driving the plug plate 210 to move upward. At this time, the infrared transmitter 29 and the receiver 211 are misaligned, and the electrical signal is transmitted to the control end. Through the displacement The sensor marks the current position and records the horizontal and vertical lengths of the bulge. Because the outer plate 26 is connected to the vertical plate 38, when the position of the infrared emitter 29 is adjusted, the position of the outer end disk 35 of the steel coil body 4 is also adjusted synchronously, so that the two disks 35 clamp the steel coil body 4. In the process of the installation component 3 and the steel coil body 4 rotating to the bottom of the detection component 2, the arc block 315 is inserted into the socket 28 to complete the transmission connection between the drive motor 27 and the connecting shaft 39. Driven by the drive motor 27, the contact between the disk 35 and the extrusion plate 311 on the two ends and the inner wall of the steel coil body 4 will drive the steel coil body 4 to rotate together, thereby cooperating with the detection component 2 for comprehensive detection.
