Film sticking machine

Abstract

The invention discloses a film sticking machine, and belongs to the technical field of magnetic material manufacturing. The film sticking machine comprises a conveying device, a positioning device, afilm sticking device and a control device. The conveying device is used for conveying tape. The tape includes a first release film and a plurality of tape units with the same outer contours as piecesto be stuck with films, the tape units are arranged on the first release film uniformly in the length direction, and the first release film is provided with a plurality of first release film units overlapping with the tape units in a cut mode. The positioning device is used for placing and positioning the pieces to be stuck with the films. The film sticking device applies certain pressure when thetape units are aligned with the pieces to be stuck with the films to enable the tape units to be attached to the pieces to be stuck with the films. The control device is used for controlling the single tape feeding length of the tape to be equal to the spacing between the initial positions of every two adjacent tape units in the tape feeding direction. The film sticking machine has high film sticking accuracy, and the tape firmly adheres to magnetic sheets and the appearance is attractive after film sticking.

Description

technical field [0001] The invention relates to the technical field of magnetic material production, in particular to a semi-automatic film laminating machine for attaching ultra-thin adhesive tape to the surface of a magnetic sheet (transmitting end) for wireless charging. Background technique [0002] At present, magnetic sheets are widely used in various industries. For example, NFC magnetic sheets and soft ferrite magnetic sheets for wireless charging will be widely used in handheld electronic devices. [0003] A film is often required on the magnetic sheet, but the magnetic sheet is made of ceramic wear-resistant materials. Generally, when the thickness exceeds 0.2mm, the mold will wear out rapidly due to the falling of the magnetic powder, so the magnetic sheet with a thickness of 0.4~1.0mm cannot be molded. Die-cut molding can only be sintered and machined into the desired shape before coating. The current way of pasting the film is usually to manually stick tape on...

[0003] A film is often required on the magnetic sheet, but the magnetic sheet is made of ceramic wear-resistant materials. Generally, when the thickness exceeds 0.2mm, the mold will wear out rapidly due to the falling of the magnetic powder, so the magnetic sheet with a thickness of 0.4~1.0mm cannot be molded. Die-cut molding can only be sintered and machined into the desired shape before laminating

The current way of pasting the film is usually to manually stick tape on both sides of the magnetic sheet for protection, which is low in work efficiency and the appearance of the fit is poor, and cannot meet the precision requirements
