[0047] The method for using the one-letter hammer falling foil device: after the free end of the connecting aluminum foil 60 and the front aluminum foil roll 70 or the free end of the rear aluminum foil roll 80 is overlapped, it is placed on the foil connecting table 10, the foil connecting frame 20 is moved, so that the hammer head 40 on the foil connecting frame 20 is located above the first overlapping area or the second overlapping area, a plurality of hanging barrels 51 are densely arranged on the dynamic adsorption plate 30, and some hanging barrels 51 can be configured with hammer heads 40 according to needs; at the beginning, the hanging assembly 50 is loaded, the first connecting piece 53 is clamped into the hanging barrel 51, the pin 56 is located between the first connecting piece 53 and the second connecting piece 55, the hammer head 40 is fixed on the hanging barrel 51 by the pin 56 through the hanging assembly 50, then the dynamic adsorption plate 30 is powered on, under the action of magnetic force, the hanging assembly 50 rises, the pin 56 is located between the second connecting piece 55 and the hammer handle 52, then the dynamic adsorption plate 30 is powered off, the hanging assembly 50 and the hammer head 40 fall freely under the action of gravity, in the falling process, the pin 56 cannot be clamped between the second connecting piece 55 and the first connecting piece 53, until the hammer head 40 falls in the first overlapping area or the second overlapping area, the aluminum foil is connected.

[0048] The one-letter hammer aluminum foil connecting method can be operated by using the one-letter hammer falling foil device.

[0049] Referring to Figures 7 to 11 A one-letter hammer aluminum foil connecting method is also provided, comprising the following steps:

[0050] The connecting aluminum foil 60 is selected;

[0051] The front end of the connecting aluminum foil 60 is overlapped with the free end of the front aluminum foil roll 70, and the part where the connecting aluminum foil 60 and the front aluminum foil roll 70 coincide in the projection direction is the first overlapping area;

[0052] The rear end of the connecting aluminum foil 60 is overlapped with the free end of the rear aluminum foil roll 80, and the part where the connecting aluminum foil 60 and the rear aluminum foil roll 80 coincide in the projection direction is the second overlapping area;

[0053] The first overlapping area and the second overlapping area are struck by the first one-letter hammer, so that the connecting aluminum foil 60 is connected with the front aluminum foil roll 70 and the rear aluminum foil roll 80.

[0054] For example, the width of the first overlapping area or the first overlapping area is 5-10 cm.

[0055] Referring to Figures 7 to 11 Further, the front end edge of the connecting aluminum foil 60 is a curved edge, and the rear end edge of the connecting aluminum foil 60 is a straight edge.

[0056] Referring to Figures 7 to 11 Further, the free end edge of the front aluminum foil roll 70 is a straight edge, and the free end edge of the rear aluminum foil roll 80 is a curved edge.

[0057] Referring to Figures 7 to 11Further, the curved edge is in a circular arc shape.

[0058] Referring to Figures 7 to 11 Further, the thickness of the front and rear aluminum foil rolls 70 and 80 is 120-137 µm, and the thickness of the connecting aluminum foil 60 is 82-95 µm.

[0059] Referring to Figures 7 to 11 Further, the thickness of the front and rear aluminum foil rolls 70 and 80 is 130 µm.

[0060] Referring to Figures 7 to 11 Further, the thickness of the connecting aluminum foil 60 is 90 µm.

[0061] Referring to Figures 7 to 11 Further, the connecting aluminum foil 60 and the front aluminum foil roll 70 corresponding to the first lap joint area and the connecting aluminum foil 60 and the front aluminum foil roll 70 corresponding to the second lap joint area are subjected to a baking treatment in advance.

[0062] After the aluminum foil is subjected to the baking treatment, the internal structure of the aluminum foil changes into a harmful structure, but the strength of the aluminum foil is improved, which is beneficial to relieving stress concentration in the hammer mark and deformation damage outside the hammer mark.

[0063] Referring to Figures 7 to 11 Further, the baking temperature is 1000-1200.

[0065] Cracks are prone to occur in the interior of the waffle hammer mark due to stress concentration, and cracks are prone to occur in the edge of the connecting aluminum foil 60 due to deformation damage of the waffle hammer mark.

[0066] After the end of the connecting aluminum foil 60 is divided, an artificial controllable crack is formed, and since the direction of the crack is consistent with the direction of the tensile force of the aluminum foil in the running process, the aluminum foil will not be torn, while the cracks caused by stress concentration or deformation damage are uncertain in position and direction, and once the cracks occur, the cracks will rapidly expand under the action of the tensile force to tear the aluminum foil.

[0067] After the end of the connecting aluminum foil 60 is divided, the distance between the interior of the waffle hammer mark and the free edge of the aluminum foil is greatly shortened, which is beneficial to stress release in the waffle hammer mark, and further reduces deformation damage of the aluminum foil outside the waffle hammer mark and generation of uncontrollable cracks.

[0068] The steps in the method of the embodiments of the present application can be adjusted in sequence, combined and reduced according to actual needs.

[0069] The modules or units in the device embodiments of the present application can be combined, divided, and deleted according to actual needs.

[0070] The above only discloses the preferred embodiments of the present application, and of course cannot limit the scope of the rights of the present application.
