DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] The following is further described in conjunction with specific embodiments. Figure 1-Figure 4 As shown, the present invention is an aluminum foil flatness detection device, comprising an unwinding mechanism 1, a rewinding mechanism 2 and a guiding mechanism 3. The unwinding mechanism 1 comprises an unwinding seat 11, an unwinding roller 12 and an unwinding motor 13. The aluminum foil roll to be detected is installed on the unwinding roller 12. The unwinding roller 12 is driven to rotate by the unwinding motor 13, so that the aluminum foil can be unwound; the rewinding mechanism 2 comprises a rewinding seat 21, a rewinding roller 22 and a rewinding motor 23. One end of the aluminum foil roll away from the unwinding roller 12 is wound on the rewinding roller 22. The aluminum foil roll can be collected by driving the rewinding roller 22 to rotate by the rewinding motor 23; the guiding mechanism 3 comprises a guiding seat 31 and a plurality of guiding rollers 32 installed on the guiding seat 31. The plurality of guiding rollers 32 are all located between the unwinding roller 12 and the rewinding roller 22, and play a guiding role for the aluminum foil.

[0026] The height of the winding roller 22 is higher than that of the unwinding roller 12 and the guide roller 32. A detection mechanism 4 is arranged between the winding seat 21 and the guide seat 31. The detection mechanism 4 can detect the flatness of the portion of the aluminum foil between the unwinding roller 12 and the guide roller 32. The detection mechanism 4 includes a detection seat 41 and a driving assembly 42 for driving the detection seat 41 to move toward or away from the winding seat 21. A plurality of laser infrared lamps 411 are distributed along the length direction of the detection seat 41. The laser infrared lamp 411 emits a light beam to the side of the aluminum foil facing the ground. The staff can judge the uneven parts by observing the positions of different light beams on the ground. After detecting one position, the detection seat 41 is driven by the driving assembly 42 to move toward or away from the winding seat 21, so that the next position can be detected until the entire section of aluminum foil in the area between the winding seat 21 and the guide seat 31 is detected.

[0027] The driving assembly 42 includes a driving motor 421 and a lead screw 422. One end of the lead screw 422 is rotatably connected to the winding seat 21, and the other end is rotatably connected to the guide seat 31. The driving motor 421 is fixedly arranged on the winding seat 21, and the output shaft of the driving motor 421 is coaxially connected to the lead screw 422. A threaded hole is provided on the detection seat 41 and is sleeved on the lead screw 422. A guide rod 43 is also provided between the winding seat 21 and the guide seat 31. The two ends of the guide rod 43 are respectively fixed on the winding seat 21 and the guide seat 31. A through hole is provided on the detection seat 41 and is sleeved on the guide rod 43. The lead screw 422 is driven to rotate by the driving motor 421. During the rotation of the lead screw 422, the detection seat 41 can move along the length direction of the lead screw 422, so as to facilitate the movement of the detection seat 41 to the next position to be detected.

[0028] The winding seat 21 is provided with a tightening mechanism 6 to tighten the rolled aluminum foil roll. The tightening mechanism 6 includes a tightening rod 61 and a tightening member 62 provided on both sides of the tightening rod 61. The tightening member 62 includes a tightening block 621 and a tightening spring 622. Both sides of the winding seat 21 are provided with a strip groove 211 along its own height direction. The tightening block 621 is slidably provided in the strip groove 211. The top surface of the tightening block 621 is provided with an arc groove that matches the shape of the tightening rod 61. One end of the tightening spring 622 is fixedly connected to the groove wall at the bottom of the strip groove 211, and the other end is fixedly connected to the tightening block 621. Under the elastic force of the tightening spring 622, the tightening block 621 drives the tightening rod 61 to move upward and tighten against the aluminum foil roll, which can improve the stability of the aluminum foil roll.

[0029] A comparison component 5 for comparing the flatness of the aluminum foil is provided between the winding seat 21 and the guide seat 31. The comparison component 5 is located on one side of the aluminum foil and the inclination angle of the comparison component 5 is consistent with the inclination angle of the aluminum foil. At least one laser infrared lamp 411 is located directly below the comparison component 5. Multiple laser infrared lamps 411 emit light beams to the comparison component 5 or the aluminum foil respectively, and the positions of the reflected light beams are observed. The light beam reflected by the aluminum foil with a smooth surface forms a straight line with the light beam reflected by the comparison component 5, while the position of the light beam reflected by the aluminum foil with an uneven surface deviates from this straight line, so that the staff can judge that the flatness of the corresponding position does not meet the standard.

[0030] The reference assembly 5 includes a reference plate 51, one end of which is provided with a rotating shaft 52 and the other end is provided with a sleeve 53, the rotating shaft 52 is rotatably mounted on the guide seat 31, and the sleeve 53 is sleeved on the outside of the abutting rod 61. When the aluminum foil is gradually wound onto the winding roller 22, the aluminum foil roll on the winding roller 22 will gradually thicken, so the inclination angle of the portion of the aluminum foil located between the unwinding roller 12 and the guide roller 32 will change, and in the process of the aluminum foil roll becoming thicker, the position of the abutting rod 61 will change synchronously. Since one end of the reference plate 51 is sleeved on the outside of the abutting rod 61 through the sleeve 53, when the position of the abutting rod 61 changes, the angle of the reference plate 51 can change synchronously, so that the inclination angle of the reference plate 51 can be consistent with the inclination angle of the portion of the aluminum foil located between the unwinding roller 12 and the guide roller 32, so as to reduce the detection error.

[0031] The working process of this embodiment is: start the unwinding motor 13 and the winding motor 23 at the same time, and make the speed of the unwinding motor 13 and the winding motor 23 consistent, so that the unwinding shaft unwinds the aluminum foil while the collecting shaft winds the aluminum foil. After unwinding for a distance, the laser infrared lamp 411 is used to detect the flatness of the portion of the aluminum foil between the unwinding roller 12 and the guide roller 32. After completing the detection of one position, the driving component 42 drives the detection seat 41 to move toward or away from the winding seat 21, so that the next position can be detected until the entire section of aluminum foil in the area between the winding seat 21 and the guide seat 31 is detected. Then start the unwinding motor 13 and the winding motor 23 again to detect the flatness of the next section of aluminum foil.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
