[0040] Any feature disclosed in this specification, unless stated otherwise, can be replaced by alternative features serving the same, equivalent or similar purpose.
[0041] In order to make the technical problems solved by the utility model, the technical scheme adopted and the technical effects reached more clear, the technical scheme of the utility model will be further explained below in combination with the drawings and through specific embodiments.
[0042] As shown in Figures 1 to 3 , the metal foil 10 has a blank foil area 102 without slurry coating and a coated area 101 with slurry coating, along the width direction of the metal foil 10, the blank foil area 102 is formed between two adjacent coated areas 101, and the extension direction of the blank foil area 102, the extension direction of the coated area 101 and the coating running direction of the metal foil 10 are parallel, as shown by arrow A in Figures 1 to 3 ; wherein, since the thickness of the coated area 101 of the metal foil 10 is thicker than the thickness of the blank foil area 102, when the metal foil 10 enters the oven for heating and drying after coating, the blank foil area 102 in the middle will be arched, shrunk and folded to wrinkle, thereby affecting the coating finished product quality of the entire metal foil 10.
[0043] Therefore, as shown in Figures 1 to 3 , the embodiment proposes a deviation correcting device for metal foil wrinkle removal, which is arranged downstream of an oven for heating and drying the metal foil 10, and the deviation correcting device for metal foil wrinkle removal in the embodiment is used to correct the deviation of the coating running direction of the metal foil 10 and stretch and flatten the wrinkles on the metal foil 10, so as to ensure the coating finished product quality of the metal foil 10.
[0044] It is worth noting that the main improvement point in the embodiment is the deviation correction and wrinkle removal of the metal foil 10, and the specific coating process of the metal foil 10 is not described in detail, and the existing coating process of the metal foil 10 can be referred to.
[0045] Specifically, as shown in Figures 2 to 4 the rectification device for removing wrinkles of metal foil material comprises a frame body 1, an arc-shaped wrinkle removing roller 2 and a fixed straight roller 3; wherein the arc-shaped wrinkle removing roller 2 is in an arc shape and is rotationally connected to the frame body 1, the highest point of the arc of the arc-shaped wrinkle removing roller 2 abuts against the metal foil material 10; the fixed straight roller 3 is rotationally connected to the frame body 1, one fixed straight roller 3 is respectively arranged upstream and downstream of the arc-shaped wrinkle removing roller 2, the coating running direction of the metal foil material 10 can be perpendicular to the axial direction of the fixed straight roller 3, and the bottom end of one of the arc-shaped wrinkle removing roller 2 and the fixed straight roller 3 abuts against the metal foil material 10, and the top end of the other abuts against the metal foil material 10, as shown in Figure 3 .
[0046] The rectification device for removing wrinkles of metal foil material in the embodiment cooperates with the arc-shaped wrinkle removing roller 2 and the two fixed straight rollers 3; by making the highest point of the arc of the arc-shaped wrinkle removing roller 2 abut against the metal foil material 10, and arranging the fixed straight rollers 3 upstream and downstream of the arc-shaped wrinkle removing roller 2, the bottom end of one of the arc-shaped wrinkle removing roller 2 and the fixed straight roller 3 abuts against the metal foil material 10, and the top end of the other abuts against the metal foil material 10; on the one hand, when the metal foil material 10 passes through the highest point of the arc of the arc-shaped wrinkle removing roller 2, the contact area between the metal foil material 10 and the arc-shaped wrinkle removing roller 2 will have a process from short to long, so that the arc-shaped wrinkle removing roller 2 will generate a pulling force from the highest point of the arc of the arc-shaped roller to the two side edges of the metal foil material 10, so as to flatten the wrinkles of the air foil area 102 by the generated pulling force, that is, the arc-shaped wrinkle removing roller 2 can play a role in eliminating the wrinkles on the metal foil material 10; on the other hand, since the bottom end of one of the arc-shaped wrinkle removing roller 2 and the fixed straight roller 3 abuts against the metal foil material 10, and the top end of the other abuts against the metal foil material 10, that is, the arc-shaped wrinkle removing roller 2 and the fixed straight roller 3 can provide opposite supporting forces for the metal foil material 10, so as to better ensure the flattening effect of the pulling force of the arc-shaped wrinkle removing roller 2 on the wrinkles on the metal foil material 10, better ensure the wrinkle removing effect of the metal foil material 10, and further ensure the coating quality of the metal foil material 10.
[0047] It is worth noting that the upstream and downstream referred to in the embodiment specifically refer to the upstream and downstream along the coating running direction of the metal foil material 10, as shown in Figure 3 . Specifically, the metal foil material 10 can be a copper foil or an aluminum foil, and the specific type of the metal foil material 10 is not limited herein.
[0048] Further, the curvature of the arc-shaped wrinkle-removing roller 2 is positively correlated with the wrinkle degree of the blank foil area 102, that is, the greater the wrinkle degree of the blank foil area 102, the greater the curvature of the arc-shaped wrinkle-removing roller 2, and the better the wrinkle-removing effect on the wrinkles of the blank foil area 102. Therefore, the curvature of the arc-shaped wrinkle-removing roller 2 can be adaptively adjusted according to the different wrinkle degrees of the blank foil area 102, so as to be applicable to the wrinkle removal of metal foil materials 10 with different wrinkle degrees, and further improve the applicability and versatility of the entire deviation rectifying device for metal foil material wrinkle removal.
[0049] Specifically, as shown in Figure 3 and Figure 4 , one end of the arc-shaped wrinkle-removing roller 2 is connected with an angle adjusting handle 21, so as to adjust the curvature of the arc-shaped wrinkle-removing roller 2 through the angle adjusting handle 21. The angle adjusting handle 21 can adopt the common angle adjusting structure in the prior art.
[0050] Specifically, as shown in Figures 2 to 4 , the outer diameter of the fixed straight roller 3 is greater than the outer diameter of the arc-shaped wrinkle-removing roller 2, so as to ensure that the fixed straight roller 3 can provide a greater supporting force for the metal foil material 10, and further ensure that the stretching force of the arc-shaped wrinkle-removing roller 2 can flatten the wrinkles of the metal foil material 10.
[0051] Further, as shown in Figure 2 and Figure 3 , the deviation rectifying device for metal foil material wrinkle removal further comprises a rotating shaft 4, a deviation rectifying roller 5 and a deviation rectifying pusher 6. The rotating shaft 4 is connected to the frame body 1, and the rotating shaft 4 is parallel to the fixed straight roller 3. The deviation rectifying roller 5 is movably arranged on the rotating shaft 4, and the deviation rectifying roller 5 is located downstream of the fixed straight roller 3 and the arc-shaped wrinkle-removing roller 2. The metal foil material 10 is arranged around the outer circumferential surface of the deviation rectifying roller 5. The deviation rectifying pusher 6 is arranged on the frame body 1, and the deviation rectifying pusher 6 is connected to the deviation rectifying roller 5. The deviation rectifying pusher 6 is used to push one end of the deviation rectifying roller 5 forward or backward along the coating and conveying direction of the metal foil material 10, so that the deviation rectifying roller 5 is inclined relative to the rotating shaft 4, and the axial direction of the deviation rectifying roller 5 is not perpendicular to the coating and conveying direction of the metal foil material 10.
[0052] By arranging the deviation rectifying roller 5 and the deviation rectifying pusher 6 to be used in cooperation, when the coating and conveying direction of the metal foil material 10 on the deviation rectifying roller 5 deviates, the deviation rectifying pusher 6 is connected to the deviation rectifying roller 5, so that the end of the deviation rectifying roller 5 can be driven to move up and down by the forward pushing or backward retreating of the deviation rectifying pusher 6, so as to swing the deviation rectifying roller 5 at an angle, and make the metal foil material 10 return to the center position of the deviation rectifying roller 5. At the same time, since the metal foil material 10 is arranged around the outer circumferential surface of the deviation rectifying roller 5, the deviation rectifying roller 5 can provide a stretching tension to the metal foil material 10. In this embodiment, up and down specifically refers toFigure 2 vertical direction in the figure.
[0053] Specifically, the deviation correction pusher 6 can include a combination structure of a straight-line cylinder and a push plate, or a combination structure of a motor, a screw rod and a push plate. Here, the specific structure of the deviation correction pusher 6 is not limited, as long as the deviation correction pusher 6 can realize the angle swing of the metal foil 10.
[0054] Further, as shown in Figure 2 , the deviation correction device for metal foil wrinkle removal further includes an ultrasonic sensor 7, the ultrasonic sensor 7 is arranged on the frame body 1, the ultrasonic sensor 7 is located downstream of the deviation correction wrinkle removal roller 5, the ultrasonic sensor 7 is used to detect whether the metal foil 10 on the deviation correction wrinkle removal roller 5 is deviated, and the ultrasonic sensor 7 is in communication connection with the deviation correction pusher 6, that is, in the case of deviation, the deviation correction pusher 6 adjusts the position of the deviation correction wrinkle removal roller 5 by a certain angle, so as to adjust the coating running direction of the metal foil 10.
[0055] Specifically, when the ultrasonic sensor 7 detects that the coating running direction of the metal foil 10 on the deviation correction wrinkle removal roller 5 is deviated, the deviation correction pusher 6 is pushed forward or backward along the coating running direction of the metal foil 10 to drive the end of the deviation correction wrinkle removal roller 5 to move up and down, so as to realize the angle swing of the deviation correction wrinkle removal roller 5, thereby realizing the deviation correction of the coating running direction of the metal foil 10.
[0056] It is worth noting that since the coating area 101 of the metal foil 10 is coated with slurry, the texture of the coating area 101 is relatively hard, so that in the above-mentioned wrinkle removal process, the stretching and flattening effect of the arc-shaped wrinkle removal roller 2 and the deviation correction wrinkle removal roller 5 on the coating area 101 is relatively small, thereby ensuring the coating stability and reliability of the coating area 101.
[0057] Further, as shown in Figure 2 and Figure 5 , the outer circumferential surface of the deviation correction wrinkle removal roller 5 is uniformly and spacedly provided with a plurality of semicircular grooves 52; on the one hand, the plurality of semicircular grooves 52 are uniformly arranged to uniformly increase the force applied to the metal foil 10 by the deviation correction wrinkle removal roller 5 during rotation, so that the deviation correction wrinkle removal roller 5 can better provide the functions of deviation correction of the coating running direction of the metal foil 10, wrinkle removal of the empty foil area 102, and stretching tension for the metal foil 10; on the other hand, by arranging the semicircular grooves 52, the stretching effect of the entire deviation correction wrinkle removal roller 5 on the wrinkles of the empty foil area 102 is more significant, and the wrinkle removal effect of the metal foil 10 is better.
[0058] Specifically, the extending direction of the semicircular slot 52 is perpendicular to the extending direction of the empty foil area 102, so as to ensure that the semicircular slot 52 can better act on the empty foil area 102, thereby better realizing the effect of the tensile crimping of the metal foil 10. The slot depth of the semicircular slot 52 is 0.5mm-3mm, that is, the radius of the semicircle of the semicircular slot 52 is 0.5mm-3mm.
[0059] Further, as shown in Figure 5 and Figure 6 , the included angle α between the center line of any two adjacent semicircular slots 52 and the center of the cross section 51 of the deviation correcting and crimping roller 5 is 10°-20°, so that the angle of the included angle α is more appropriate, avoiding the problem of poor tensile crimping effect of the metal foil 10 caused by too large or too small angle, thereby better realizing the crimping effect of the entire deviation correcting and crimping roller 5. In the embodiment, the included angle α is 15°, that is, 24 semicircular slots 52 are uniformly arranged on the outer circumferential surface of the deviation correcting and crimping roller 5.
[0060] Specifically, the material of the deviation correcting and crimping roller 5 is mirror aluminum material; on the one hand, the mirror aluminum material can reduce the friction damage between the deviation correcting and crimping roller 5 and the metal foil 10, and protect the crimping function of the semicircular slot 52 from being reduced; on the other hand, due to the smooth outer circumferential surface of the mirror aluminum material of the deviation correcting and crimping roller 5, the gas in the crimping of the empty foil area 102 is more easily entered into the semicircular slot 52 during the crimping process, thereby easily realizing the opening of the crimping, and making the crimping more simple and fast. The mirror aluminum material specifically refers to an aluminum plate treated by rolling, polishing and other methods, so that the surface of the plate presents a mirror effect. The surface of the mirror aluminum is smooth like a mirror, and has high reflectivity.
[0061] Further, as shown in Figure 2 and Figure 3 , the frame body 1 includes a main frame body 11, a first support 12 and a second support 13; the first support 12 is connected to the main frame body 11, and the arc-shaped crimping roller 2 and the fixed straight roller 3 are connected to the first support 12; the second support 13 is connected to the main frame body 11, and the second support 13 is arranged in a spaced manner with the first support 12, and the deviation correcting and crimping roller 5 is arranged on the second support 13. Here, the specific structure of the main frame body 11, the first support 12 and the second support 13 is not limited, as long as the supporting and mounting effect can be realized by the main frame body 11, the first support 12 and the second support 13.
[0062] By setting the first support 12 and the second support 13 independently, the arc-shaped wrinkle-removing roller 2 and the fixed straight roller 3 are independently arranged with the deviation-correcting wrinkle-removing roller 5, and do not interfere with each other; when the deviation-correcting wrinkle-removing roller 5 downstream swings to correct and remove wrinkles, the position of the arc-shaped wrinkle-removing roller 2 and the fixed straight roller 3 on the first support 12 and the position of the metal foil 10 thereon are not affected, so that the stability and reliability of the arc-shaped wrinkle-removing roller 2 and the deviation-correcting wrinkle-removing roller 5 can be ensured. The main frame 11 is further rotationally connected with a plurality of guide rollers 8, and the metal foil 10 is arranged around each guide roller 8 to provide guidance and support for the coating track of the metal foil 10.
[0063] The deviation-correcting device for metal foil wrinkle removal in the embodiment can stretch and flatten the wrinkles of the empty foil area 102 while ensuring the supporting effect on the metal foil 10 by setting the arc-shaped wrinkle-removing roller 2 and the fixed straight roller 3 used in cooperation with each other; and the deviation-correcting wrinkle-removing roller 5 with a plurality of uniformly arranged semicircular grooves 52 can better provide the deviation correction of the coating track direction of the metal foil 10, wrinkle removal of the empty foil area 102, and stretching tension for the metal foil 10.
[0064] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
