This type of equipment is used by printed circuit board manufacturers and is also used in the production of flexible circuit boards in automotive electronics, 3C electronics, and other fields.

[0003] Currently, this type of cutting equipment uses a motor-driven roller to feed the film, while a pneumatic cylinder controls the circular reciprocating motion of the cutter blades. This structure makes it impossible to adjust the gap between the blades, and the scissor-like cutting method results in imperfect cuts.

[0004] Specifically, the film cuts are prone to jagged burrs. Furthermore, wrinkles may occur due to abnormal extrusion, leading to abnormal cut edges.

[0005] In view of the above-mentioned defects, the designer has actively carried out research and innovation in order to create a thin film slicer flat cutting equipment to make it more valuable for industrial use. Utility Model Content

[0020] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figure 1 The thin film slicer flat-cutting device includes a device base 1. Its uniqueness lies in: a driving roller 2 is movably connected to the device base 1, and a rotary drive device 3 is installed on the driving roller 2 to facilitate active rotary drive. At the same time, a displacement adjustment device 5 is also installed on the device base 1, and a driven roller 4 is connected to the displacement adjustment device 5, which is used to drive the driven roller 4 to move up and down reciprocatingly. The driven roller 4 is located above the driving roller 2. In this way, the driving roller 2 and the driven roller 4 cooperate with each other to achieve stable feeding in conjunction with the operation of the film feeding equipment, and ensure that it has appropriate ductility to facilitate subsequent flat-cutting processing. In addition, considering the need for subsequent flush adjustment of the incision, the device base 1 is located in front of the driving roller 2 and is equipped with a flat-cutting device.

[0030] In view of a preferred embodiment of the present invention, the rotary drive device 3 is a servo motor, which is connected to the active roller 2 through a coupling. In this way, continuous and stable rotary drive can be achieved, and the stable supply of film can be achieved in accordance with the actual feeding rate. At the same time, in order to realize the real-time and convenient adjustment of the position of the driven roller 4, the displacement adjustment device 5 is a cylinder device, which includes a mirror-distributed cylinder body connected to the equipment base 1, and the driven roller 4 is connected between the cylinder bodies. Of course, for some special application needs, an electric cylinder can also be used to form the displacement adjustment device 5. In addition, considering the smooth passive operation of the driven roller 4, auxiliary bearings are installed on the cylinder body, and the two ends of the driven roller 4 are connected to the auxiliary bearings.

[0031] The flat cutting device includes a lower cutter 6 fixedly connected to the device base 1. A cutter drive 7 is located at both ends of the lower cutter 6, mirroring each other. An upper cutter 8 is mounted on the cutter drive 7, and the cutting edge of the upper cutter 8 corresponds to that of the lower cutter 6. Thus, the cutter drive 7 drives the upper cutter 8 to move up and down, enabling rapid vertical severing of the film without creating a jagged fracture texture.

[0032] Specifically, the cutter drive device 7 includes a cutter cylinder mirrored at the front end of the device base 1. A cutter fixture is mounted between the cutter cylinders, and the upper cutter blade 8 is connected to the cutter fixture. This ensures effective vertical movement of the upper cutter blade 8. Furthermore, to compensate for lateral tolerances that may occur during assembly, the present invention incorporates a transverse adjustment block 9 mounted on the drive end of the cutter cylinder and a transverse connecting rod 10 on the cutter fixture. Both ends of the transverse connecting rod 10 are connected to the transverse adjustment block 9. This allows for adjustment of the cutting gap between the lower cutter blade 6 and the upper cutter blade 8, reducing distance tolerances and achieving the shortest possible cutting path, further avoiding jagged cross-sections and ensuring a smooth cut. Furthermore, the transverse connecting rod 10 is provided with several mounting holes, each of which is connected by screws. The upper cutter blade 8 is screwed to the transverse connecting rod 10. This allows for quick replacement of the corresponding upper cutter blade 8 as needed, facilitating subsequent maintenance and easy assembly and disassembly.

[0033] Furthermore, the base 1 of the device used in the present invention includes a base body, with supporting brackets extending from both ends of the base body, and bearing assemblies mounted on the supporting brackets. The driving roller 2 is connected to the bearing assembly and then connected to the rotation drive device 3. This can reduce the turning resistance of the driving roller 2 under normal driven rotation, and smoothly feed the film.

[0034] The working principle of this utility model is as follows:

[0035] The driven roller 4 is first lifted appropriately to allow the film from the external feeding equipment to enter the feeding gap formed by the active roller 2 and the driven roller 4. The driven roller 4 reciprocates up and down, and under the premise of the active roller 2 rolling, the feeding gap is effectively controlled to ensure the continuous forward movement of the film.

[0036] After the film reaches the length to be cut, the flat cutting device is activated, and the cutting edges of the upper cutter 8 and the lower cutter 6 cooperate with each other to achieve vertical flat cutting, ensuring a flat cross section.

[0037] After that, continuous operation can meet the needs of sequential slicing of the film.

[0038] It can be seen from the above text description and the accompanying drawings that the present invention has the following advantages:

[0039] 1. Through the mutual cooperation of the active roller and the driven roller, the film can be moved forward continuously and stably without jumping up and down, and avoiding feeding wrinkles and skew.

[0040] 2. The independent transverse adjustment block can adjust the relative position of the upper and lower cutting edges of the cutter to ensure a smooth cross section and avoid improper cutting and tearing.

[0041] 3. The horizontal cutting device adopts a vertical cutting layout to avoid the jagged section caused by circular arc reciprocating motion and has a flat cutting section.

[0042] 4. The overall structure is simple and can be adapted to various conventional cover film laser cutting equipment to achieve preset cutting of the film before laser processing.

[0043] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated in a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
