Description

Technical Field

[0001] The invention relates to automatic laminating equipment, in particular to automatic alignment gap laminating equipment. Background Art

[0002] In the battery industry, precise bonding equipment is often required to composite different film materials together. During the automatic bonding movement, the film material will be significantly offset during rotation. The offset mainly includes three aspects: angle offset, position offset, or both angle and position offset. This will cause the final composite material to be uneven and affect the quality of the product. The prior art already has a solution based on automatic visual recognition and then using a deviation corrector for correction. For example, a Chinese invention patent with patent number "202310318371.3" discloses a closed-loop method based on a lithium battery bonding process, and discloses a solution using a deviation corrector for correction. However, when using this deviation corrector to correct the position offset, although it can correct the offset to a certain extent, this method will produce an angle offset (the bonding position is equivalent to the fixed position of the film, and the deviation corrector rotates the film relative to the fixed position of the film).

[0003] In addition, when laminating rectangular sheets of films to be laminated with intervals to the rolled base film, it is difficult to accurately align each sheet of the films to be laminated using only a deflection corrector. Insufficient lamination accuracy may result in excessive intervals between the films to be laminated, which may also cause waste of base film or waste film materials. Summary of the invention

The automatic alignment gap bonding equipment of this embodiment collects the position data of the film to be composited and the bottom film through the visual recognition module, and controls the moving seat of the UVW adjustment platform to move according to the collected position data so that the film to be composited and the bottom film are aligned. When the film to be composited and the bottom film are in a parallel state and there is a positional offset, the translation alignment of the film to be composited and the bottom film can be achieved, and the distortion of the film to be composited and the distortion, bubbles and other undesirable phenomena can be avoided, so as to achieve precise alignment and precise composite.

[0028] In this embodiment, a first power roller group 7, a bottom film adsorption and positioning seat 8 and a second power roller group 9 are sequentially arranged on the frame 1 and along the unwinding direction of the bottom film 1001, and the composite mechanism 6 is arranged between the bottom film adsorption and positioning seat 8 and the second power roller group 9.

[0029] In this embodiment, the UVW adjustment platform 4 is located directly below the bottom film adsorption and positioning seat 8 , and the unwinding and peeling mechanism 3 for the film to be composited is located directly above the bottom film adsorption and positioning seat 8 .

[0030] In this embodiment, the film to be laminated unwinding and peeling mechanism 3 comprises: a moving frame 31, a film to be laminated unwinding roller 32, a film to be laminated peeling assembly 33 and a waste film collecting roller 34; the film to be laminated unwinding roller 32 is arranged on the moving frame 31, and is used to unwind the film to be laminated 1002; the film to be laminated peeling assembly 33 is arranged on the moving frame 31, and is used to separate the film to be laminated 1002 from the waste film 1003; the waste film collecting roller 34 is arranged on the moving frame 31, and is used to collect the separated waste film 1003.
