[0035] As shown in Figures 1-7 The mounting frame 1 is provided with a cleaning assembly 15 between the peeling knife 3 and the composite foil winding roller 6, and the servo motor 5 provides driving force for the cleaning assembly 15.

[0039] The material of the cleaning roller 1503 has the property of mutual adhesion with the carrier film adhesive.

[0040] When the servo motor 5 starts, the drive gear 1501 is driven to rotate forward. The drive gear 1501 drives the transmission gear 1502 to rotate reversely through gear engagement. The transmission gear 1502 drives the cleaning roller 1503 to rotate reversely through the second transmission belt 1504. The cleaning roller 1503 cleans the residual adhesive on the composite foil when rotating. The adhesive adhered to the cleaning roller 1503 is scraped off when the cleaning roller 1503 rotates to the scraper 1506, and falls into the collection groove 1508 along the scraper slope 1507 for collection and processing, which facilitates the winding and subsequent reprocessing of the composite foil and improves the work efficiency.

[0041] The mounting frame 1 is provided with a bearing plate 11, the bearing plate 11 is located below the cleaning roller 1503, the distance between the bearing plate 11 and the lowest point of the cleaning roller 1503 is the thickness of the composite foil with the bearing film, the end face of the bearing plate 11 close to one end of the winding part 2 is a first circular arc surface 12, the end face of the bearing plate 11 away from one end of the winding part 2 is a second circular arc surface 13, the second circular arc surface 13 is provided with a pressure sensor 14, and the pressure sensor 14 is electrically connected with the servo motor 5.

[0043] Meanwhile, when the composite foil is wound through the bearing plate 11, pressure is generated on the pressure sensor 14, when the rotating speed of the servo motor 5 is too fast, the tension of the composite foil is increased, and the pressure on the second circular arc surface is also increased, at this moment, the pressure sends an electric signal, the rotating speed of the servo motor 5 is slowed down, the composite foil is prevented from being torn due to the too fast winding speed, and the peeling quality is ensured.

[0044] The working principle of the utility model is as follows:

[0045] The composite foil is first punched, the bearing film is pasted on one side, the metal layer is deposited on the other side, the bearing film is peeled off, the bearing film is pasted on the side of the deposited metal layer, and finally the bearing film is peeled off. The utility model is used for peeling off the bearing film on the composite foil, and in use, a section of the bearing film is manually peeled off, the peeled composite foil is wound on the composite foil winding roller 6, the bearing film is wound on the bearing film winding roller 7, the servo motor 5 is started, the servo motor 5 drives the composite foil winding roller 6 to rotate, the composite foil winding roller 6 drives the bearing film winding roller 7 to rotate synchronously through the first transmission belt 8, and the composite foil winding roller 6 and the bearing film winding roller 7 drive the composite foil with the bearing film to move towards the composite foil winding roller 6. When the bearing film and the composite foil are separated from each other when contacting the peeling knife 3 in the moving process, the automatic peeling of the bearing film is realized, the bearing film winding roller 7 and the composite foil winding roller 6 are rotated to drive the composite foil with the bearing film to feed, the composite foil has a certain tension during peeling, the folding and bending are reduced, and the peeling quality and working efficiency of the bearing film are ensured.

[0046] The composite foil is output from the roll feeding piece 2 and moves forward along the clamping plate 9 and then is peeled off. Since the gap height in the middle of the clamping plate 9 is the same as the thickness of the composite foil with the carrier film, the thickness of the composite foil with the carrier film moving to the peeling knife 3 is ensured to be uniform, the peeling knife 3 can accurately peel off the bonding part of the carrier film and the composite foil, and the folding and curling of the composite foil with the carrier film output from the roll feeding piece 2 do not affect the peeling effect of the carrier film, and the peeling quality is improved.

[0047] The composite foil output from the clamping plate 9 passes through the guide roller 10 and then is peeled off by the peeling knife 3. Since the position of the peeling knife 3 is fixed, the height of the composite foil with the carrier film reaching the peeling knife 3 should be uniform, and the height of the guide roller 10 is the same as that of the peeling knife 3, so that the peeling knife 3 can accurately perform the peeling operation, the positioning inaccuracy is prevented, the composite foil is not damaged, and the peeling quality is ensured.

[0048] When the servo motor 5 is started, the driving gear 1501 is driven to rotate in the positive direction, the driving gear 1501 drives the transmission gear 1502 to rotate in the reverse direction through the gear meshing effect, the transmission gear 1502 drives the cleaning roller 1503 to rotate in the reverse direction through the second transmission belt 1504, the cleaning roller 1503 cleans the adhesive remaining on the composite foil during rotation, the adhesive adhered to the cleaning roller 1503 is scraped off when the cleaning roller 1503 rotates to the scraper 1506, and the adhesive falls into the collection groove 1508 along the inclined surface 1507 of the scraper to be collected and processed, facilitating the winding and subsequent reprocessing of the composite foil and improving the work efficiency.

[0049] The composite foil is easy to bend, so when the cleaning roller 1503 adheres the adhesive, the composite foil may be bent due to the pressure, affecting the cleaning of the adhesive. The carrier plate 11 provides support for the composite foil and ensures the flatness of the composite foil, ensuring the winding effect.

[0050] When the composite foil is wound through the carrier plate 11, the pressure sensor 14 is subjected to pressure. When the rotation speed of the servo motor 5 is too fast, the tension of the composite foil increases, and the pressure on the second arc surface also increases. At this time, the pressure sends an electric signal to control the servo motor 5 to slow down the rotation speed, so as to prevent the composite foil from being torn due to the too fast winding speed, and ensure the peeling quality.

[0051] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
