The top plate and the bottom plate are integrally connected by a connecting plate (connecting rod), and particularly, the connecting plate (connecting rod) is disposed at one side, so that the electrolytic copper foil reel change auxiliary device 400 is formed as a whole.
Further, the electrolytic copper foil change assist device 400 is also provided with a moving member so that the electrolytic copper foil change assist device 400 can move in the a direction and the B direction (a connecting plate (connecting rod) of the electrolytic copper foil change assist device 400 is connected to a bottom plate, and moving wheels (universal wheels) are provided under the bottom plate).

An electrolytic copper foil forming machine comprises a first guide roller assembly 100, a second guide roller assembly 200, a wind-up roller 300 and a press roller assembly 500;
the copper foil passes through the first guide roller assembly 100 and the second guide roller assembly 200 in sequence and is finally wound on the winding roller 300.
One of the improvements is that:
the first guide roller assembly 100 includes: an upper guide roller and a lower guide roller;
the second guide roller assembly 200 includes: an upper lifting guide roller and a lower lifting guide roller;
in normal operation, the copper foil passes through the upper guide roller and the lower guide roller of the first guide roller assembly 100, passes through the upper elevating guide roller and the lower elevating guide roller of the second guide roller assembly 200, and is finally wound up to the take-up roller.
By maintaining the level from the first guide roller assembly 100 to the second guide roller assembly 200, the design is intended to be coordinated with the electrolytic copper foil change assist apparatus 400.
The second improvement is that:
a nip roll assembly 500 comprising: top plate structure 501, compression roller assembly lifting device 508, platform plate 509, 2 vertical rods 502, compression roller end bearing assembly 504, compression roller 505 and sliding wheel 507;

The second original design of improvement is that the compression roller is directly placed in the vertical strip-shaped sliding groove, and the design is not suitable, wherein the compression roller rotates, and the compression roller moves up and down in the vertical strip-shaped sliding groove; the two motion modes lead the compression roller to be in direct contact with the vertical strip-shaped sliding groove, the friction resistance of the contact surface is large, and the end part of the compression roller can be damaged.
The inventor creatively solves the problems.
In addition, the end of the top plate structure 501 is also provided with a sliding wheel 507, and the matching design is provided with: a horizontal rail 600. That is, the platen roller assembly 500 is carried on the horizontal rails 600, and the platen roller assembly 500 can move back and forth in the a direction.

Namely, the height of the winding roller can be adjusted up and down (the height of the winding roller is adjusted up and down in the winding process instead of the winding process, and the specific function is in the working process).
One of the improvements, the second of the improvements, and the third of the improvements are an integral design for roll change of a copper foil forming machine.
When the winding roll is replaced by the electrolytic copper foil forming machine, the working process is as follows:
s1, the moving wheel of the electrolytic copper foil rewind assisting device 400 is started to arrange the electrolytic copper foil rewind assisting device 400 between the first guide roller assembly 100 and the second guide roller assembly 200:
starting a moving wheel of the electrolytic copper foil change auxiliary device 400, firstly moving the electrolytic copper foil change auxiliary device 400 along the direction A to reach a preset position, and then along the direction B to enable an upper tensioning control device component of the electrolytic copper foil change auxiliary device 400 to be above a copper foil, and a lower tensioning control device component of the electrolytic copper foil change auxiliary device 400 to be below the copper foil, wherein the copper foil firstly passes below a first tensioning control device 401 and then passes below a second tensioning control device 402;
s2, when the copper foil needs to be replaced by a winding roller, the copper foil is clamped and cut, and the old winding roller is moved away:
the upper tensioning control device assembly and the lower tensioning control device assembly of the electrolytic copper foil change auxiliary device 400 are both started, and when the electrolytic copper foil is pressed, the moving wheels of the electrolytic copper foil change auxiliary device 400 are started (the first tensioning control device 401 and the second tensioning control device 402 are at the same height, and the third tensioning control device 403 and the fourth tensioning control device 404 are at the same height, namely the first tensioning control device 401 and the second tensioning control device 402 are at the same height and on the upper surface of the copper foil horizontal plane, and the third tensioning control device 403 and the fourth tensioning control device 404 are at the same height and on the original copper foil horizontal plane), so that the electrolytic copper foil change auxiliary device 400 moves towards the winding roll along the direction A, and the moving speed of the electrolytic copper foil change auxiliary device 400 is equal to the linear speed of the cathode roll;
when the electrolytic copper foil is pressed, the B direction telescopic rod 407-2 is started, the moving part 407-3 drives the cutting knife 407-4 to move along the B direction, and the copper foil is cut, namely the copper foil contacted with the first tensioning control device and the third tensioning control device is separated from the copper foil contacted with the second tensioning control device and the fourth tensioning control device;
s3, replacing the wind-up roll:
s3-1, lifting a second tensioning control device, descending a fourth tensioning control device, and immobilizing a first tensioning control device and a third tensioning control device;
s3-2, the upper lifting guide roller of the second guide roller assembly 200 is lifted, and the lower lifting guide roller is lowered;
s3-3, separating the old winding roller from the driving part, removing the old winding roller (the end part of the copper foil wound by the old winding roller is in an unstressed state and can be removed), and then driving the bottom plate 508 to descend by the telescopic mechanism 509; meanwhile, the press roll assembly lifting device 508 is started to separate the press roll from the copper foil roll of the old wind-up roll: the platform plate is lifted, and then the press roller is lifted (as the press roller assembly lifting device 508 is started, the platform plate needs to be lifted to a certain distance, the press roller bearing assembly 504 is contacted with the lower surface of the vertical strip-shaped sliding groove, and then the press roller bearing assembly 504 and the press roller continuously lift);
s3-4, installing a new winding roller in place, namely connecting the new winding roller with a driving part;
s4, the electrolytic copper foil rewinding auxiliary device 400 continues to move, the copper foil contacts with the new rewinding roller (the new rewinding roller is adhered with glue on the surface), and rewinding starts:
s4-1, after the upper lifting guide roll of the second guide roll assembly 200 is lifted and the lower lifting guide roll is lowered, the electrolytic copper foil change auxiliary device 400 passes through the lower part of the upper lifting guide roll and the upper part of the lower lifting guide roll (here, the requirement is that the height of the upper lifting guide roll can be higher than the top plate of the electrolytic copper foil change auxiliary device 400, and the height of the lower lifting guide roll can be lower than the bottom plate of the electrolytic copper foil change auxiliary device 400);
s4-2, the electrolytic copper foil change auxiliary device 400 continues to move forward, and after the electrolytic copper foil change auxiliary device 400 passes through a new winding roller, the telescopic mechanism 509 drives the bottom plate 508 to ascend until the topmost end of the new winding roller contacts the electrolytic copper foil; at the same time, the platen assembly elevator 508 is activated and the platen is lowered a distance until the platen contacts the copper foil, at which point the platen continues to be lowered a distance (subject to the constraint that the vertical bar does not contact the central rotating shaft of the new cathode roll).
S5, after the step S4-2, the upper lifting guide roller of the second guide roller assembly 200 descends and the lower lifting guide roller ascends until the two contact with the copper foil;
meanwhile, the first drawing control device 401 and the first drawing control device 403 are separated from each other; then the moving wheel of the electrolytic copper foil change auxiliary device 400 is started, and the electrolytic copper foil change auxiliary device 400 is arranged between the first guide roller assembly 100 and the second guide roller assembly 200 (firstly moves along the direction B and then moves along the direction A; in the process, the direction B is started to the telescopic rod 407-2, and the moving part 407-3 drives the cutting knife 407-4 to return to the initial position);
s6, the pressing roller moves back and forth along the direction a to press the copper foil originally pressed by the first tension control device 401 and the first tension control device 403 against the winding roller:
the top plate structure 501 advances to drive the platform plate 509, the 2 vertical rods 502, the pressing roller end bearing assembly 504 and the pressing roller 505 to move back and forth (one movement is needed) along the direction a, and in the process, the pressing roller end bearing assembly 504 can move up and down in the vertical strip-shaped sliding grooves of the vertical rods 502.
From the above steps, the copper foil behind the first guide roller assembly 100 in S1 to S6 is always kept in a horizontal state during the reel change.
The second embodiment is modified in that:
the cutter device 407 includes: a fixed part 407-1, a B-direction telescopic rod 407-2, a moving part 407-3, a knife handle, a cutting knife 407-4 and a Z-direction telescopic rod 407-5;
the lower surface of the moving part 407-3 is connected with the fixed end of a Z-direction telescopic rod 407-5, the movable end of the Z-direction telescopic rod 407-5 is connected with a knife handle, and the end part of the knife handle is provided with a cutting knife 407-4;
i.e., the height of the cutting blade 407-4 can be adjusted.
The second embodiment is to improve the general use of the electrolytic copper foil reel-change assisting device 400. That is, the electrolytic copper foil reel-change assisting device 400 can be used in a plurality of copper foil production line. However, there is no copper foil on each copper foil production line (the height of the copper foil between the first guide roll assembly 100 and the second guide roll assembly 200 is different, and therefore, in order to increase the versatility of the electrolytic copper foil change assist apparatus 400, the height-adjustable function of the cutting blade 407-4 is added).
When the winding roll is replaced by the electrolytic copper foil forming machine, the working process is as follows:
on the basis of the method of example 1, the following changes were made:
there were changes in S1 and S2:
s1, first, the moving wheel of the electrolytic copper foil rewind assisting device 400 is started to arrange the electrolytic copper foil rewind assisting device 400 between the first guide roller assembly 100 and the second guide roller assembly 200:
starting a moving wheel of the electrolytic copper foil change auxiliary device 400, firstly moving the electrolytic copper foil change auxiliary device 400 along the direction A to reach a preset position, and then along the direction B to enable an upper tensioning control device component of the electrolytic copper foil change auxiliary device 400 to be above a copper foil, and a lower tensioning control device component of the electrolytic copper foil change auxiliary device 400 to be below the copper foil, wherein the copper foil firstly passes below a first tensioning control device 401 and then passes below a second tensioning control device 402;
secondly, adjust the height of cutting sword 407-4: the Z-direction telescopic rod 407-5 is started to adjust the cutting knife 407-4 to be lowered to reach the preset cutting height.
S2, when the copper foil needs to be replaced by a winding roller, the copper foil is clamped and cut, and the old winding roller is moved away:
the upper tensioning control device assembly and the lower tensioning control device assembly of the electrolytic copper foil change auxiliary device 400 are both started, and when the electrolytic copper foil is pressed, the moving wheels of the electrolytic copper foil change auxiliary device 400 are started (the first tensioning control device 401 and the second tensioning control device 402 are at the same height, and the third tensioning control device 403 and the fourth tensioning control device 404 are at the same height, namely the first tensioning control device 401 and the second tensioning control device 402 are at the same height and on the upper surface of the copper foil horizontal plane, and the third tensioning control device 403 and the fourth tensioning control device 404 are at the same height and on the original copper foil horizontal plane), so that the electrolytic copper foil change auxiliary device 400 moves towards the winding roll along the direction A, and the moving speed of the electrolytic copper foil change auxiliary device 400 is equal to the linear speed of the cathode roll;
when the electrolytic copper foil is pressed, the B direction telescopic rod 407-2 is started, the moving part 407-3 drives the cutting knife 407-4 to move along the B direction, and the copper foil is cut, namely the copper foil contacted with the first tensioning control device and the third tensioning control device is separated from the copper foil contacted with the second tensioning control device and the fourth tensioning control device;
after cutting, the Z-direction telescopic rod 407-5 is started, and the height of the cutting knife 407-4 is adjusted to rise to return to the initial state.
In the third embodiment, the first step is that,
in addition to the embodiment 1 or 2, an electrolytic copper foil forming machine employs 2 electrolytic copper foil change auxiliary devices 400. The parent of the above design is to solve the following problems: when the rewinding speed is slow, there may be a case where "the distance of the copper foil from the wind-up roll to the first drawing control device 401 is larger than tr/2 (r represents the radius of the wind-up roll)" when the wind-up roll is in contact with the electrolytic copper foil at step S6, and in this case, the press roll cannot bond the entire copper foil to the wind-up roll.
When the winding roll is replaced by the electrolytic copper foil forming machine, the working process is as follows:
s1, starting the moving wheel of the first electrolytic copper foil change auxiliary device and the moving wheel of the second electrolytic copper foil change auxiliary device, uniformly arranging the moving wheel starting of the first electrolytic copper foil change auxiliary device and the moving wheel starting of the second electrolytic copper foil change auxiliary device between the first guide roller assembly 100 and the second guide roller assembly 200, and arranging the first electrolytic copper foil change auxiliary device behind the second electrolytic copper foil change auxiliary device (along the copper foil advancing direction, the first guide roller assembly 100, the second electrolytic copper foil change auxiliary device, the first electrolytic copper foil change auxiliary device, the second guide roller assembly 200 and the wind-up roller in sequence):
starting a moving wheel of the first electrolytic copper foil change auxiliary device, firstly moving the first electrolytic copper foil change auxiliary device along the direction A to reach a preset position, and then along the direction B to enable an upper tensioning control device component of the first electrolytic copper foil change auxiliary device to be above the copper foil, and a lower tensioning control device component of the first electrolytic copper foil change auxiliary device to be below the copper foil, wherein the copper foil firstly passes below a first tensioning control device 401 and then passes below a second tensioning control device 402;
s2, when the copper foil needs to be replaced by the roll changing roller, the first electrolytic copper foil roll changing auxiliary device clamps the copper foil and cuts the copper foil, and the old winding roller is removed:
the upper tensioning control device assembly and the lower tensioning control device assembly of the first electrolytic copper foil change auxiliary device are both started, and when the electrolytic copper foil is pressed, the first tensioning control device 401 and the second tensioning control device 402 are at the same height, and the third tensioning control device 403 and the fourth tensioning control device 404 are at the same height, namely the first tensioning control device 401 and the second tensioning control device 402 are at the same height and on the upper surface of the copper foil horizontal plane, and the third tensioning control device 403 and the fourth tensioning control device 404 are at the same height and on the original copper foil horizontal plane, the moving wheel of the first electrolytic copper foil change auxiliary device is started, so that the first electrolytic copper foil change auxiliary device moves towards the winding roll along the direction A, and the moving speed of the first electrolytic copper foil change auxiliary device is equal to the linear speed of the cathode roll;
when the electrolytic copper foil is pressed, the B direction telescopic rod 407-2 is started, the moving part 407-3 drives the cutting knife 407-4 to move along the B direction, and the copper foil is cut, namely the copper foil contacted with the first tensioning control device and the third tensioning control device is separated from the copper foil contacted with the second tensioning control device and the fourth tensioning control device;
s3, replacing the wind-up roll:
s3-1, lifting a second tensioning control device of the first electrolytic copper foil reel changing auxiliary device, descending a fourth tensioning control device, and immobilizing a first tensioning control device and a third tensioning control device;
s3-2, the upper lifting guide roller of the second guide roller assembly 200 is lifted, and the lower lifting guide roller is lowered;
s3-3, separating the old winding roller from the driving part, removing the old winding roller (the end part of the copper foil wound by the old winding roller is in an unstressed state and can be removed), and then driving the bottom plate 508 to descend by the telescopic mechanism 509; meanwhile, the press roll assembly lifting device 508 is started to separate the press roll from the copper foil roll of the old wind-up roll: the platform plate is lifted, and then the press roller is lifted (as the press roller assembly lifting device 508 is started, the platform plate needs to be lifted to a certain distance, the press roller bearing assembly 504 is contacted with the lower surface of the vertical strip-shaped sliding groove, and then the press roller bearing assembly 504 and the press roller continuously lift);
s3-4, installing a new winding roller in place, namely connecting the new winding roller with a driving part;
s4, the first electrolytic copper foil roll changing auxiliary device continues to move until the first electrolytic copper foil roll changing auxiliary device passes through a new winding roller:
after the upper lifting guide roll of the second guide roll assembly 200 is lifted and the lower lifting guide roll is lowered, the first electrolytic copper foil change auxiliary device passes through the lower part of the upper lifting guide roll and the upper part of the lower lifting guide roll (here, the requirement is that the height of the upper lifting guide roll can be higher than the top plate of the first electrolytic copper foil change auxiliary device, and the height of the lower lifting guide roll can be lower than the bottom plate of the first electrolytic copper foil change auxiliary device);
then passes through the second guide roller assembly 200 and then passes through a new wind-up roller;
if the new winding roller is installed in place, the projection distance of the middle rotating shaft of the new winding roller and the first drawing control device of the first electrolytic copper foil lap changing auxiliary device on the horizontal plane is smaller than pi r/2 (more preferably, the threshold value is pi r/8);
then the following steps are taken:
s5, contacting the copper foil with a new winding roller (glue is adhered on the surface of the new winding roller), and starting winding: the first electrolytic copper foil change auxiliary device continues to move forward, and when the first electrolytic copper foil change auxiliary device passes through a new winding roller, the telescopic mechanism 509 drives the bottom plate 508 to ascend until the topmost end of the new winding roller contacts the electrolytic copper foil; at the same time, the platen assembly elevator 508 is activated and the platen is lowered a distance until the platen contacts the copper foil, at which point the platen continues to be lowered a distance (subject to the constraint that the vertical bar does not contact the central rotating shaft of the new cathode roll).
S6, after step S5, the upper lifting guide roller of the second guide roller assembly 200 descends and the lower lifting guide roller ascends until both contact the copper foil;
