Abstract

The present invention discloses an aluminum foil flatness detection mechanism and device. The mechanism is arranged between aluminum foil tensioning mechanisms and includes a blowing nozzle, a displacement sensor, and a moving component. The blowing nozzle can blow air towards the aluminum foil to form a local tensioned area on the aluminum foil. The detection point of the displacement sensor falls within the local tensioned area. The relative positions of the blowing nozzle and the displacement sensor remain unchanged. The moving component can drive the blowing nozzle and the displacement sensor to move along the width direction of the aluminum foil. In the present invention, the blowing nozzle blows air towards the aluminum foil to locally tension the aluminum foil, and then the displacement sensor detects the flatness of the aluminum foil in the tensioned area. Compared with the single-direction tensioning in the prior art, blowing can locally tension the aluminum foil in all directions, so the detection accuracy is higher.

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the accompanying drawings and specific embodiments are merely exemplary and should not be construed as imposing any limitation on the protection scope of the present invention.

[0030] As Figure 1 shown, the embodiment of the present invention provides an aluminum foil flatness detection device, which includes an aluminum foil flatness detection mechanism 100, and also includes an aluminum foil unwinding rack assembly 200, a pressing mechanism 300, a tensioning mechanism 400 and a force-applying mechanism 500. The aluminum foil unwinding rack assembly is used to carry the aluminum foil roll. After the aluminum foil on the aluminum foil roll passes through the pressing mechanism 300 and the aluminum foil flatness detection mechanism 100 in sequence, it is tensioned by the tensioning mechanism 400 and the force-applying mechanism 500.

[0031] Among them, the structure of the aluminum foil flatness detection mechanism 100 is as Figure 2 and Figure 3 shown, and it includes a blowing nozzle 101, a displacement sensor 102 and a moving assembly 103. The blowing nozzle 101 can be connected to an air pump through a hose, so as to be able to blow air towards the aluminum foil to form a local tensioned area on the aluminum foil. The detection point of the displacement sensor 102 falls within the local tensioned area. The displacement sensor 102 can be a laser displacement sensor, which can detect the distance from the detection point on the aluminum foil to the sensor. The relative positions of the blowing nozzle 101 and the displacement sensor 102 should remain unchanged. The moving assembly 103 can drive the blowing nozzle 101 and the displacement sensor 102 to move along the width direction of the aluminum foil.

[0032] The tensioning mechanisms in the prior art can only tension the aluminum foil in one direction or two directions, and there may still be slack or wrinkles in some areas, and it is impossible to ensure that the tension degrees of each detection point are consistent. While tensioning the aluminum foil in one direction, the present invention ensures that each local area can be tensioned by blowing air, so as to be able to achieve very high-precision flatness detection.

[0033] It is easily understandable to those skilled in the art that the air-blowing nozzle 101 and the displacement sensor 102 can be arranged on the same side of the aluminum foil or on different sides of the aluminum foil, as long as the air-blowing point and the detection point are located at the same position. In a possible embodiment, the air-blowing nozzle 101 and the displacement sensor 102 are relatively arranged on the upper and lower sides of the aluminum foil, so that both the air-blowing nozzle 101 and the displacement sensor 102 are perpendicular to the aluminum foil, and the detection effect is the best. At this time, the detection point of the displacement sensor 102 is located on the convex surface of the locally tensioned area of the aluminum foil.

[0034] The moving component 103 only needs to be able to drive the air-blowing nozzle 101 and the displacement sensor 102 to move along the width direction of the aluminum foil. Therefore, common driving mechanisms such as a motor cooperating with a belt or a lead screw can be adopted. In a possible embodiment, the moving component 103 includes a motor, an upper synchronous track, and a lower synchronous track. The upper synchronous track includes an upper conveyor belt, upper synchronous wheels, an upper slide rail, and upper sliders. The lower synchronous track includes a lower conveyor belt, lower synchronous wheels, a lower slide rail, and lower sliders. The upper sliders are slidably engaged with the upper slide rail, and the motor drives the upper sliders through the upper conveyor belt. The lower sliders are slidably engaged with the lower slide rail. The lower synchronous wheels are drivingly connected to the lower sliders by means of the lower conveyor belt. The air-blowing nozzle 101 is arranged on the upper sliders, and the displacement sensor 102 is arranged on the lower sliders. The upper synchronous wheels and the lower synchronous wheels are connected by means of a transmission belt, so that the air-blowing nozzle 101 and the displacement sensor 102 can always maintain an upper and lower synchronous position.

[0035] As Figure 4 shown, the overall assembly 200 of the aluminum foil unwinding rack includes a base 201 and two bearing seats 202. Two sections of slide rails 203 are arranged on the base, and the two bearing seats 202 are respectively slidably engaged with these two sections of slide rails 203, so that the distance and position between the bearing seats 202 can be adjusted as needed. Bearing pairs 204 for bearing the aluminum foil winding shaft 205 are arranged on both of the two bearing seats 202. The aluminum foil winding shaft 205 is externally tangent to the bearing pairs 204, so that it can be applicable to aluminum foil winding shafts 204 with different diameters.

[0036] In order to be able to further finely adjust the distance between the bearing pairs 204, a feeding fine-tuning component 260 can also be arranged on the bearing seat. The structure of the feeding fine-tuning component 260 is as Figure 5As shown in the figure, it includes a second slide rail 261, a base 262, a fine adjustment lead screw 263, a fine adjustment lead screw nut 264 and a handwheel 265. The second slide rail 261 is parallel to the slide rail 203. The base 262 is arranged on the second slide rail 261. The bearing pair 204 is arranged on the base 262. The fine adjustment lead screw nut 264 is fixedly connected to the base 262. The lead screw 263 is arranged parallel to the second slide rail 261. The handwheel 265 is drivingly connected to the lead screw 263. The fine adjustment lead screw nut 264 is threadedly connected to the fine adjustment lead screw 263. When the handwheel 265 is rotated, the fine adjustment lead screw nut 264 moves along the fine adjustment lead screw 263, thereby driving the base 262 to slide on the second slide rail 261.

[0037] As Figure 6 shown in the figure, the blank holding mechanism 300 includes a lifting cylinder 301, an upper clamping block 302, a lower clamping block 303 and a support frame 305. The lifting cylinder 301 is fixedly arranged on the support frame 305. The driving end of the lifting cylinder 301 is drivingly connected to the upper clamping block 302 and drives the upper clamping block 302 to move up and down. The lower clamping block 303 is arranged below the upper clamping block 302. When the upper clamping block 302 moves downward, it clamps the aluminum foil together with the lower clamping block 303.

[0038] In addition, mechanisms such as guide wheels and guide frames can be arranged behind the blank holding mechanism 300 to make the height of the aluminum foil consistent with the required height of the flatness detection mechanism.

[0039] At the other end of the equipment, there are a tensioning mechanism 400 and a force adding mechanism 500. As Figure 7 and Figure 8 shown in the figure, the tensioning mechanism 400 includes a third slide rail 401, a profile frame 402 and a tensioning tube 403. The third slide rail 401 is arranged along the aluminum foil conveying direction. The profile frame 402 is arranged on the third slide rail 401. A bearing seat 404 is arranged on the profile frame 402. The tensioning tube 403 includes an upper cover 403a and a tube body 403b. The upper cover 403a is arranged on the tube body 403b through a knurling knob 405. Both ends of the tube body 403b are arranged in the bearing seat 404 and can thus rotate. One end of the tube body 403b is connected to a handwheel 406. In addition, a lifting ring 407 for connecting to the force adding mechanism 500 is arranged on the profile frame 402. When it is necessary to tension the aluminum foil, first pass the aluminum foil through between the upper cover 403a and the tube body 403b, then tighten the upper cover 403a and the tube body 403b through the knurling knob 405, and then rotate the handwheel 406 to make the tube body 403b rotate to realize the tensioning of the aluminum foil.

[0040] As Figure 9 and Figure 10As shown in the figure, the force - increasing mechanism 500 includes a manual adjustment component and an electric adjustment component. The manual adjustment component includes a rocker 501, an adjustment screw rod 502, and an adjustment screw rod nut (not shown in the figure). The rocker 501 is in transmission connection with the adjustment screw rod. The adjustment screw rod nut is threadedly connected to the adjustment screw rod 502. The electric adjustment component is fixedly connected to the adjustment screw rod nut. The electric adjustment component includes a motor 504 and a movable block 505. The motor 504 drives the movable block 505 to move linearly. A hook 506 is arranged on the movable block 505. The hook 506 is connected to the suspension ring 407 by means of a steel wire (not shown in the figure).

[0041] Further, in order to make the force on the steel wire more reasonable, a first guiding roller and a second guiding roller are also arranged on the profile frame 402. One end of the steel wire is connected to the suspension ring 407, and the other end is connected to the hook 506 after passing around the first guiding roller 408 and the second guiding roller 409 in sequence.

[0042] The detection process of this equipment is as follows: Place the aluminum foil roll on the aluminum foil unwinding rack assembly 200, pass the aluminum foil through the pressure - applying mechanism 300 and the detection mechanism 100, and then fix it on the tensioning mechanism 400. Ensure that both ends of the aluminum foil in the detection section are tightened by the force - increasing mechanism 500 and the pressure - applying mechanism 300. Then start the aluminum foil flatness detection mechanism 100. The air - blowing nozzle 101 and the displacement sensor 102 move along the width direction of the aluminum foil, and the positions of each detection point to the displacement sensor 102 are made into a waveform diagram and displayed on the display screen, so that the flatness of the aluminum foil roll can be observed.

[0043] In summary, the aluminum foil flatness detection equipment of the present invention realizes semi - automatic detection of the flatness of the aluminum foil by setting up an aluminum foil flatness detection mechanism, an aluminum foil unwinding rack assembly, a pressure - applying mechanism, a tensioning mechanism, and a force - increasing mechanism. Among them, the aluminum foil flatness detection mechanism blows air towards the aluminum foil through the air - blowing nozzle to make the aluminum foil locally tensioned, and then detects the flatness of the aluminum foil in the tensioned area through the displacement sensor. Compared with the single - direction tensioning in the prior art, blowing air can make the aluminum foil locally tensioned in all directions, so the detection accuracy is higher.
