All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The copper foil shearing machine provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
The inventors found that the number of pressing members in the related art is plural, the plural pressing members press and fix different portions of the stacked copper foil sheet in the width direction thereof, respectively, and the width of each pressing member is small, and the contact area of the pressing member having a small width with the copper foil sheet is small, so that the pressing force exerted by the pressing members on the copper foil sheet is concentrated, and since the pressing members are in contact with only a partial area of the copper foil sheet in the width direction, the concentrated pressing force exerted by the pressing members only brings about bending deformation of a portion of the copper foil sheet located in the vicinity of the contact point, and a portion of the copper foil sheet located in the width direction thereof away from the vicinity of the contact point is restrained against the copper foil sheet at the contact point, thereby preventing bending deformation thereof, and causing a crease of the copper foil sheet in the vicinity of the contact point.
As shown in fig. 1 to 10, an embodiment of the present application discloses a copper foil cutter, which comprises an unreeling device 100, a cutting device 200 and a stacking device 300 sequentially arranged in a first direction (the direction indicated by the x arrow line in fig. 1 and 3), wherein the stacking device 300 comprises a stacking table 400 and a pressing member 500, and the stacking table 400 is provided with a stacking area for stacking copper foils 700. Specifically, the unreeling device 100 is used for releasing the copper foil roll, the released tape reel head is led out from the unreeling device 100 and then passes through the shearing device 200, the shearing device 200 is used for shearing the continuous copper foil roll to be sheared into the copper foil 700, and the copper foil 700 can be conveyed to the stacking region of the stacking table 400 from the outlet side of the shearing device 200.
Alternatively, the shape of the stacking area herein is adapted to the shape of the copper foil 700, which may be rectangular or square. In addition, referring to fig. 2 and 10, the stacking apparatus 300 may further include a translation mechanism 600, where the translation mechanism 600 can move between the shearing apparatus 200 and the stacking table 400, and the translation mechanism 600 has a clamping assembly 610 thereon, and the clamping assembly 610 can clamp the copper foil 700 so as to convey the copper foil 700 from the outlet side of the shearing apparatus 200 to the stacking area of the stacking table 400; the specific working process is as follows, when the translation mechanism 600 moves to the inlet side of the shearing device 200, the clamping component 610 can clamp the tape reel head of the copper foil reel, then the shearing device 200 shears the copper foil reel positioned at the outlet side into the copper foil 700, and the translation mechanism 600 moves towards the stacking table 400 to convey the copper foil 700 to the stacking area; alternatively, the clamping assembly 610 may include a clamping cylinder 611 and a clamping plate 612 disposed opposite to each other with a clamping space between the clamping cylinder 611 and the clamping plate 612 for accommodating the copper foil 700, and a piston rod of the clamping cylinder 611 can be moved closer to or farther from the clamping plate 612 to clamp or release the copper foil 700.
The pressing member 500 includes a driving part 510 and a pressing assembly 520, the pressing assembly 520 includes a pressing part 530 extending in a second direction (a direction indicated by y arrow lines in fig. 1 and 3), and both ends of the pressing part 530 are respectively flush with or beyond corresponding edges of the stacking region in the second direction, that is, the pressing part 530 continuously extends from one side to the other side of the stacking region in the second direction, wherein the second direction intersects the first direction, and the second direction extends in a horizontal direction. Alternatively, the second direction may be perpendicular to the first direction, or may be inclined with respect to the first direction.
Specifically, since the stacking region is adapted to the shape of the copper foil 700, each edge of the stacking region is respectively flush with each edge of the copper foil 700 stacked to the stacking region, the copper foil 700 has a third edge 730 and a fourth edge 740 disposed opposite to each other in the second direction, and the third edge 730 and the fourth edge 740 are respectively flush with both edges of the stacking region in the second direction, so that one end of the pressing member 530 is flush with or beyond the third edge 730 of the copper foil 700 and the other end of the pressing member 530 is flush with or beyond the fourth edge 740 of the copper foil 700 when the stacked copper foil 700 is pressed by the pressing member 530.
The driving member 510 is connected with the pressing assembly 520 and can drive the pressing assembly 520 to move between a pressing position and an avoiding position, and in the case that the pressing assembly 520 is located at the pressing position, the pressing member 530 is opposite to the stacking area in the vertical direction, and the pressing member 530 can press the stacked copper foil 700; with the pressing assembly 520 in the evasion position, the pressing assembly 520 is away from the stacking region to evade the copper foil 700 to be stacked.
The specific operation is as follows, before the copper foil 700 is transferred to the stacking area, the pressing assembly 520 is located at the pressing position, so as to press and fix the stacked copper foil 700, and since the pressing member 530 is located above the stacked copper foil 700 when the pressing assembly 520 is located at the pressing position, the pressing member 530 is located between the copper foil 700 to be stacked and the stacking area when the copper foil 700 to be stacked is transferred to the stacking area, namely: the copper foil 700 to be stacked is located above the pressing member 530, under the obstruction of the pressing member 530, the copper foil 700 to be stacked cannot be stacked to the stacking area, so that the pressing member 520 needs to be far away from the stacking area and move to the avoiding position to avoid the copper foil 700 to be stacked, and in the process that the pressing member 520 moves to the avoiding position, the pressing member 530 can be in contact with the copper foil 700 to be stacked, and under the condition that the pressing member 520 is located at the avoiding position, the pressing member 530 is no longer located between the copper foil 700 to be stacked and the stacking area, and does not obstruct the copper foil 700 to be stacked, so that the copper foil 700 to be stacked can be stacked to the stacking area.
In the embodiment of the application, the pressing component 520 includes the pressing member 530 extending along the second direction, and two ends of the pressing member 530 are respectively flush with or beyond corresponding edges of the stacking area in the second direction, so after the copper foil 700 is stacked to the stacking area, two ends of the pressing member 530 are respectively flush with or beyond corresponding edges of the copper foil 700 in the second direction, that is, when the pressing member 530 is away from and contacts with the copper foil 700 to be stacked, the pressing member 530 contacts with all parts of the copper foil 700 in the second direction, so that the contact area of the pressing member 530 and the copper foil 700 can be increased, the pressure exerted by the pressing member 530 on the copper foil 700 is dispersed, and since the pressing member 530 contacts with all parts of the copper foil 700 in the second direction, the pressing member 530 can drive all parts of the copper foil 700 in the second direction to bend and deform, in this case, the copper foil 700 does not have a portion capable of restricting deformation of the contact point of the copper foil 700 in the second direction, and thus the copper foil 700 can be prevented from generating a crease near the contact point.
It should be noted that, the driving member 510 may drive the pressing assembly 520 to rotate from the pressing position to the avoiding position and/or move to the avoiding position, and the movement mode of the pressing assembly 520 from the pressing position to the avoiding position is not limited in the present application.
Since the pressing member 530 contacts the copper foil 700 to be stacked during the movement of the pressing assembly 520 from the pressing position to the avoiding position, in order to further prevent the pressing member 530 from creasing the copper foil 700 to be stacked when contacting the copper foil 700 to be stacked, in an alternative embodiment, referring to fig. 8 and 9, the pressing member 530 has a guiding portion 531, the guiding portion 531 has a guiding arc surface 5311, the altitude of the guiding arc surface 5311 in the first direction is gradually reduced when the pressing assembly 520 is located at the pressing position, and the guiding arc surface 5311 can contact the copper foil 700 to be stacked during the movement of the pressing assembly 520 from the pressing position to the avoiding position. Specifically, the altitude herein refers to the distance between the material camber 5311 and the ground plane.
In this embodiment, the pressing member 530 has a guiding portion 531, the guiding portion 531 has a guiding cambered surface 5311, and in the process of moving the pressing assembly 520 from the pressing position to the avoiding position, the guiding cambered surface 5311 contacts with the copper foil 700 to be stacked, that is, the guiding cambered surface 5311 is a convex cambered surface, and since the guiding cambered surface 5311 has a curvature, the contact area between the guiding cambered surface 5311 and the copper foil 700 to be stacked is larger, the pressure exerted by the guiding cambered surface 5311 on the copper foil 700 to be stacked is distributed more uniformly, so that the occurrence of local pressure concentration can be reduced; in addition, the guiding cambered surface 5311 is smoother, and the friction force generated when the guiding cambered surface 5311 contacts with the copper foil 700 to be stacked is smaller, so that the guiding cambered surface 5311 can be prevented from being worn and scratched to the copper foil 700 to be stacked. Of course, the pressing member 530 may not have the guiding cambered surface 5311, which is not limited by the present application.
In an alternative embodiment, referring to fig. 8, the pressing assembly 520 further includes a connecting member 540, the connecting member 540 and the material guiding portion 531 are sequentially distributed in the first direction, the driving member 510 is connected to the connecting member 540, the pressing member 530 further includes a supporting portion 532, and two ends of the supporting portion 532 are respectively connected to the material guiding portion 531 and the connecting member 540, that is, the connecting member 540, the supporting portion 532 and the material guiding portion 531 are sequentially distributed in the first direction.
The connection member 540 has a supporting plane 5431, a top edge of the guiding cambered surface 5311 is higher than the supporting plane 5431, the supporting portion 532 has a supporting cambered surface 5321, the supporting plane 5431 and the supporting cambered surface 5321 are both used for supporting the copper foil 700 to be stacked, and the top edge of the supporting cambered surface 5321 extends to the top edge of the guiding cambered surface 5311 and is tangential to the guiding cambered surface 5311, that is, in the first direction, the altitude of the supporting cambered surface 5321 is gradually increased. For convenience of explanation, the embodiment is illustrated by taking the orientation shown in fig. 8 as an example, the pressing member 530 further has a supporting portion 532, the supporting portion 532 has a supporting arc surface 5321, the supporting arc surface 5321 is used for supporting the copper foil 700, that is, the supporting arc surface 5321 is a convex arc surface, and the left side of the supporting arc surface 5321 has a supporting plane 5431 connected with the supporting arc surface 5321, before the pressing component 520 moves from the pressing position to the avoiding position, and when the copper foil 700 to be stacked is conveyed to the stacking device 300, the left side of the copper foil 700 is lapped on the supporting arc surface 5321 and the supporting plane 5431, since the top edge of the supporting arc surface 5321 is higher than the supporting plane 5431, the copper foil 700 is lapped on the supporting arc surface 5321 and the supporting plane 5431 obliquely, and a gap is formed between the portion of the copper foil 700 adjacent to the supporting arc surface 5321 and the supporting plane 5431, that is, the contact area between the copper foil 700 and the supporting arc surface 5321 and the supporting plane 5431 is smaller, so that when the copper foil 700 is combined with the following embodiment of the driving member 510 including the lifting driving member 511 and the horizontal displacement driving member 512", the copper foil 700 can be stacked, and the risk of scratching the copper foil 700 to be stacked can be reduced when the copper foil 700 is stacked can be moved upwards and the combined and the copper foil 700 is to be scratched and the risk of being pressed by the copper foil to be stacked is reduced. It should be noted that the top edge of the supporting cambered surface 5321 should not be too high above the supporting plane 5431, which can prevent the copper foil 700 from generating a larger falling distance when supported on the supporting cambered surface 5321 and the supporting plane 5431, so as to prevent the copper foil 700 from generating folds.
Alternatively, the bottom edge of the guiding cambered surface 5311 may extend to the supporting plane 5431, or the bottom edge of the guiding cambered surface may not extend to the supporting plane 5431, where the supporting plane 5431 and the guiding cambered surface may be connected by a plane, a curved surface, or the like.
In another alternative embodiment, referring to fig. 9, the pressing assembly 520 further includes a connection member 540, the connection member 540 and the guiding portion 531 are sequentially distributed in the first direction, the driving member 510 is connected to the connection member 540, the connection member 540 is connected to the guiding portion 531, the connection member 540 has a supporting plane 5431 for supporting the copper foil 700 to be stacked, and the supporting plane 5431 is tangent to the top edge of the guiding cambered surface 5311. For convenience of explanation, the embodiment takes the orientation shown in fig. 9 as an example, when the copper foil 700 to be stacked is conveyed to the stacking device 300 before the pressing assembly 520 moves from the pressing position to the avoiding position, the left side of the copper foil 700 will overlap the supporting plane 5431 and be attached to the supporting plane 5431, that is, the copper foil 700 will not generate a falling distance on the supporting plane 5431, and no gap exists between the left side of the copper foil 700 and the supporting plane 5431, so that the copper foil 700 can be prevented from generating folds under the effect of environmental air pressure and other factors.
In an alternative embodiment, referring to fig. 8 and 9, the pressing member 530 has a pressing portion 533, the pressing portion 533 has a pressing arc surface 5331, and a portion of the pressing arc surface 5331 in its circumferential direction can press the stacked copper foil 700. In this embodiment, the pressing portion 533 has a pressing arc surface 5331, where the pressing arc surface 5331 is capable of pressing the stacked copper foil 700, that is, the pressing arc surface 5331 is a convex arc surface, when the pressing member 530 is inclined relative to the stacked copper foil 700 during movement, this may enable different portions of the pressing arc surface 5331 in the circumferential direction to press the stacked copper foil 700, and since the pressing arc surface 5331 has a curvature, when pressing the stacked copper foil 700, different portions of the pressing arc surface 5331 in the circumferential direction are tangential to the stacked copper foil 700, which may enable a larger contact area between the pressing arc surface 5331 and the stacked copper foil 700, so that the pressure applied by the pressing arc surface 5331 on the copper foil 700 is dispersed, so as to prevent the pressing arc surface 5331 from generating a crease when pressing the copper foil 700. Of course, the pressing portion 533 of the present embodiment may not have the pressing arc surface 5331, in which case the pressing portion 533 may have a pressing plane capable of pressing the stacked copper foil 700.
It should be noted that, when the present embodiment is combined with the embodiment that the pressing member 530 has the material guiding portion 531 and the embodiment that the pressing member 530 further has the supporting portion 532, two ends of the pressing arc surface 5331 may be tangent to the bottom end of the material guiding arc surface 5311 and the bottom end of the supporting arc surface 5321, respectively, and the pressing member 530 is in a circular tube shape.
In an alternative embodiment, referring to fig. 4 and 5, the pressing assembly 520 further includes a connecting member 540 connected to the pressing member 530, the connecting member 540 extends along the second direction, the connecting member 540 and the pressing member 530 are sequentially distributed in the first direction, the driving member 510 is connected to the connecting member 540, and the connecting member 540 is provided with a vent hole 542 penetrating through in the thickness direction thereof. For convenience, the embodiment is explained by taking the orientation shown in fig. 4 and 5 as an example, during the process of moving the pressing assembly 520 from the avoidance position to the pressing position, the pressing assembly 520 gradually approaches the stacked copper foil 700, that is, the connection member 540 and the pressing member 530 gradually approach the stacked copper foil 700 until the pressing member 530 presses and fixes the connection member 540 to the stacked copper foil 700, and since the connection member 540 extends along the second direction, the connection member 540 has a certain length in the second direction, a pressure difference is formed in front of and behind the connection member 540 gradually approaches the stacked copper foil 700, thereby forming an air flow, and the air flow may lift the stacked copper foil 700, causing the phenomenon of interlayer dislocation of the stacked copper foil 700; in the present embodiment, the through ventilation holes 542 are formed in the connection member 540, and the ventilation holes 542 balance the pressure in front of and behind the connection member 540 during the process of gradually approaching the connection member 540 to the stacked copper foil 700, so as to reduce the disturbance of air flow, which can prevent the stacked copper foil 700 from being lifted up to cause interlayer misalignment. Of course, the connecting member 540 may not be provided with the vent holes 542, which is not limited by the present application.
In an alternative embodiment, referring to fig. 4 and 5, the ventilation holes 542 are arranged in at least two groups, at least two groups of ventilation holes 542 are distributed at intervals along the first direction, each group of ventilation holes 542 includes a plurality of sub-holes arranged at intervals along the second direction, and the sub-holes of two adjacent groups of ventilation holes 542 are arranged in a staggered manner along the first direction. In this embodiment, the ventilation holes 542 are provided with at least two groups, each group of ventilation holes 542 includes a plurality of sub-holes, and the sub-holes of two adjacent groups are arranged in a staggered manner in the first direction, which can increase the number of ventilation holes 542 on the connection member 540, and can improve the uniformity of distribution of the sub-holes in the second direction, so as to better balance the pressure in front of and behind the connection member 540, and further prevent the stacked copper foil 700 from being lifted. Of course, the sub-holes of the vent holes 542 of adjacent two sets may also be opposite in the first direction; or the vent holes 542 may be provided in only one group, and the number of sub-holes of the vent holes 542 in the group may be at least one, and the present application is not limited to the number of groups of vent holes 542 and the positional relationship between sub-holes of each group of vent holes 542.
In an alternative embodiment, referring to fig. 7, the connecting member 540 is a plate-shaped structural member, the connecting member 540 includes a supporting section 543 and a mounting section 544 which are bent relatively, the mounting section 544 is located at the lower side of the supporting section 543, the supporting section 543 is connected to the pressing member 530 and is used for supporting the copper foil 700 to be stacked, the driving member 510 is connected to the mounting section 544, a reinforcing rib 550 is disposed between the bottom surface of the supporting section 543 and the mounting section 544, and the reinforcing rib 550 and the sub-holes of each set of ventilation holes 542 are arranged in a staggered manner in the first direction. In this embodiment, since the pressing member 530 applies a vertical downward force to the stacked copper foil 700 when located at the pressing position, the stacked copper foil 700 applies a vertical upward reaction force to the pressing member 530, and the pressing member 530 is connected to the supporting section 543 of the connecting member 540, so that the supporting section 543 is also subjected to a vertical upward reaction force, and in order to prevent the supporting section 543 from bending upwards under the action of the reaction force, the reinforcing ribs 550 are disposed between the supporting section 543 and the mounting section 544, and the supporting section 543 is limited to bending upwards by the reinforcing ribs 550, so that the pressing member 530 connected thereto can apply a larger pressing force to the stacked copper foil 700; in addition, since the sub-holes of each set of ventilation holes 542 are offset from the reinforcing ribs 550, this can prevent the reinforcing ribs 550 from obstructing the flow of gas to better balance the pressure in front of and behind the connection 540.
In an alternative embodiment, referring to fig. 5 and 6, the driving member 510 includes a lifting driving member 511 and a horizontal displacement driving member 512, wherein the lifting driving member 511 is used for driving the pressing assembly 520 to move in a vertical direction, and the horizontal displacement driving member 512 is used for driving the pressing assembly 520 to move in a first direction and a reverse direction. Alternatively, the lifting drive member 511 and the horizontal displacement drive member 512 may each be a cylinder, an electric cylinder, a screw-nut drive mechanism, a rack-and-pinion drive mechanism, a crank drive mechanism, or the like, which is not limited by the present application.
The specific working process is as follows, after the copper foil 700 to be stacked is conveyed above the stacking area, the pressing assembly 520 needs to move from the pressing position to the avoiding position, the lifting driving member 511 drives the pressing assembly 520 to move upwards, and the horizontal displacement driving member 512 drives the pressing assembly 520 to move along the opposite direction of the first direction, so that the pressing assembly 520 is located at the side of the stacking area to avoid the copper foil 700 to be stacked, and at this time, the copper foil 700 to be stacked can be stacked in the stacking area; after the copper foil 700 to be stacked is stacked in the stacking area, the pressing assembly 520 needs to be moved from the avoiding position to the pressing position, and the horizontal displacement driving member 512 drives the pressing assembly 520 to move along the first direction, so that the pressing member 530 is opposite to the copper foil 700 to be stacked, and the lifting driving member 511 drives the pressing assembly 520 to move downwards again, so that the pressing member 530 presses and fixes the stacked copper foil 700. As can be seen, the embodiment of the present application drives the pressing assembly 520 to move downward by the elevation driving member 511, so that the pressing member 530 presses and fixes the stacked copper foil 700, such that the force applied thereto by the pressing member 530 when pressing and fixing the stacked copper foil 700 extends in a vertically downward direction, that is, the pressing member 530 does not apply a component force in a horizontal direction to the stacked copper foil 700, preventing the pressing member 530 from causing the stacked copper foil 700 to move in a horizontal direction, thereby causing interlayer misalignment.
Alternatively, the lifting driving member 511 may be directly connected to the pressing member 520, and at this time, the horizontal displacement driving member 512 may be directly connected to the lifting driving member 511, and the lifting driving member 511 directly drives the pressing member 520 to lift, and the horizontal displacement driving member 512 directly drives the lifting driving member 511 to move along the first direction and the opposite direction, thereby indirectly driving the pressing member 520 to move along the first direction and the opposite direction. Or the horizontal displacement driving member 512 may be directly connected to the pressing assembly 520, and at this time, the lifting driving member 511 may be directly connected to the horizontal displacement driving member 512, and the horizontal displacement driving member 512 may directly drive the pressing assembly 520 to move in the first direction and the opposite direction, and the lifting driving member 511 directly drives the horizontal displacement driving member 512 to lift, thereby indirectly driving the pressing assembly 520 to lift.
In order to prevent the stacked copper foil 700 from being unable to be pressed to the misaligned copper foil 700 by the pressing member 530 after the interlayer misalignment, in an alternative embodiment, the stacking region has a first edge 710 and a second edge 720 sequentially distributed along the first direction, and the minimum distance between the pressing member 530 and the first edge 710 is 25mm to 35mm when the pressing member 520 is located at the pressing position, that is, the minimum distance between the pressing member 530 and the edge of the stacked copper foil 700 corresponding to the first edge 710 is 25mm to 35mm when the copper foil 700 is stacked in the stacking region. In this embodiment, when the pressing component 520 is located at the pressing position, the minimum distance between the pressing component 530 and the edge corresponding to the stacked copper foil 700 is 25 mm-35 mm, so that even if the stacked copper foil 700 is dislocated between layers, and the distance between the dislocated layers is smaller than the minimum distance, the pressing component 530 of this embodiment can press and fix the dislocated copper foil 700; also, the minimum distance of the present embodiment is less than 35mm, so that the extension length of the pressing member 530 may be reduced, thereby shortening the time for the pressing assembly 520 to move from the pressing position to the withdrawing position, and the reduction of the extension length of the pressing member 530 may also increase the rigidity of the pressing member 530, thereby enabling the pressing member 530 to press and fix the stacked copper foil sheets 700 better. Of course, the minimum distance between the pressing member 530 and the first edge 710 may also be less than 25mm, or greater than 35mm, with the pressing assembly 520 in the pressing position.
