The stacking structure 200 is used to stack multiple white film units and press the stacked multiple white film units to form a protective layer 400, thereby improving the subsequent production efficiency of ceramic capacitors.

[0035] See also Figures 1 to 3 In some embodiments, the cutting structure 600 includes a transverse cutting component 601 for cutting the white film layer along a first direction and a longitudinal cutting component 602 for cutting the white film layer along a second direction, and the first direction is perpendicular to the second direction.

[0036] It can be understood that the first direction and the second direction are both arranged in the horizontal direction, the longitudinal cutting component 602 can cut along the length direction of the white film layer, and the cross-cutting component 601 can cut along the width direction of the white film layer. As the material is discharged, the longitudinal cutting component 602 and the cross-cutting component 601 continue to operate, so that the white film layer can be cut into multiple linearly arranged white film units.

[0037] See also Figures 1 to 3In some embodiments, the cross-cutting assembly 601 includes a first gantry 6011 spanning the feeding channel 704, a first lifting drive 6013 disposed on the first gantry 6011, and a first cutter 6012 for cutting the white film layer, two first lifting drives 6013 are arranged at intervals, and the first cutter 6012 is disposed on both first lifting drives 6013.

[0038] It can be understood that the first lifting driver 6013 drives the first cutter 6012 to descend and abut against the white film layer. As the white film layer moves along the feeding channel 704 , the white film layer can be passively cut by the first cutter 6012 .

[0039] See also Figures 1 to 3 In some embodiments, the longitudinal cutting assembly 602 includes a second gantry 6021 spanning the feeding channel 704 and spaced apart from the first gantry 6011, a second lifting drive 6024 slidably connected to the second gantry 6021 along a second direction, a longitudinal cutting drive 6022 connected to the second gantry 6021 and used to drive the second lifting drive 6024, and a second cutter 6023 for cutting the white film layer, and the second cutter 6023 is connected to the second lifting drive 6024.

The stripping plate 801 slides to the material transfer mechanism, and the material transfer mechanism absorbs the white film unit on the stripping plate 801. At the same time, the stripping plate 801 slides in a direction away from the material transfer mechanism, so that the base layer and the white film unit are separated. At this time, the base layer corresponding to the white film unit moves toward the receiving barrel 702, and the stripping plate 801 reloads a new white film unit. The stripping plate 801 continues to move to the material transfer mechanism to continue to peel the white film unit from the base layer.

[0065] See also Figures 1 to 3 In some embodiments, the capping machine 1000 further includes a control structure for controlling the feeding structure 700 , the cutting structure 600 and the stacking structure 200 .

[0066] See also Figures 1 to 3 In some embodiments, the material transfer robot 208 includes a material transfer gantry 2081 arranged along the sliding direction of the stripping plate 801, a material transfer lifting driver 2082 slidably connected to the material transfer gantry 2081, and a vacuum adsorption plate 2083 connected to the material transfer lifting driver 2082.

[0067] Optionally, the material transfer gantry 2081 spans the material transfer station 101 and extends to the sliding range of the stripping plate 801. When the stripping plate 801 slides to the extreme position toward the material transfer station 101, the material transfer lifting driver 2082 slides to above the stripping plate 801 and drives the vacuum adsorption plate 2083 to move downward, so that the vacuum adsorption plate 2083 uses negative pressure to adsorb the white film unit from the stripping plate 801. At this time, the stripping plate 801 slides in the direction away from the material transfer station 101 to achieve passive stripping of the white film unit, and the vacuum adsorption plate 2083 places the adsorbed white film unit on the first loading tray 201 located at the material transfer station 101.

For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
