Description

Film peeling device

The present invention relates to a film peeling device, in particular to a film peeling device that uses a clamp to peel off the film.

Press, in the semiconductor or electronic component industry, it is necessary to attach a film (including adhesive film, Mylar film) on the substrate to serve as a construction layer or adhesive for subsequent processes. Regarding the manufacturing process of some printed circuit boards, a circuit pattern is constructed on the core layer and then covered with ABF film (Ajinomoto Build-up Film) for insulation purposes. Afterwards, the ABF film can be removed for subsequent packaging or welding processes.

Due to the thin thickness of the ABF film and its high adhesion to the surface of the circuit board, it is difficult to use the existing peeling device to remove the ABF film. At present, the industry still generally uses manual methods to remove ABF films.

In view of the above problems, the present invention discloses a film peeling device, which helps to solve the problem that the existing film peeling device is difficult to peel off the ABF film.

The film peeling device disclosed in the present invention includes a rotating main body, a film material suction part and a film material clamping part. The film material suction part is disposed on an outer peripheral surface of the rotating body, and the film material clamping part is movably disposed on an outer peripheral surface of the rotating body.

Another disclosed film peeling device of the present invention includes a rotating body and at least one film material suction member. The rotating main body includes at least one narrow tube part with a smaller radial dimension and two wide tube parts with a larger radial dimension, and the narrow tube part is between the two wide tube parts. The film material suction part is movably arranged on the outer peripheral surface of the narrow tube part.

The film peeling device further disclosed in the present invention includes a main body, a film material suction part and a film material clamping part. The main body has an arc-shaped outer surface, a through groove and a guide groove. The through groove and the guide groove are connected to the arc-shaped outer surface, and the guide groove extends along the arc-shaped outer surface. The film material suction part is movably arranged in the through groove. The film material clamping member is movably arranged in the guide groove.

According to the film stripping device disclosed in the present invention, the film material clamping member is movably disposed on the outer peripheral surface of the rotating body. After the film material suction part lifts off a part of the film from the base plate, the film material clamping part can hold the lifted part of the film, and then the film can be completely removed after the main body is rotated. The film material clamp can provide additional clamping force so that the peeled off part of the film can be fixed to the main body, which helps to make the removal of the film easier.

In addition, the film material suction part can be movably arranged on the main body, and the film material suction part can move along the radial direction of the main body. In this way, the external force for lifting off the film is not only the suction force from the film material suction part, but also the positive pulling force generated by the movement of the film material suction part in the radial direction, making it easier to lift off the film.

In addition, the rotating body may include a narrow tube part with a smaller radial dimension and a wide tube part with a larger radial dimension, and the film material suction part and/or the film material clamping part may be provided at the narrow tube part. The film and substrate are clamped through the wide tube part, and the film material suction part can move relative to the narrow tube part to absorb the film. In this way, the film can be peeled off at multiple positions through multiple film material suction parts, so that the force of peeling off the film can be evenly distributed.

The above description of the present disclosure and the following description of the embodiments are used to demonstrate and explain the spirit and principles of the present invention, and to provide further explanation of the patent application scope of the present invention.

Furthermore, the through groove 120 extends along the radial direction D1 of the main body 10 , and the guide groove 130 extends along the outer peripheral surface 110 , that is, the guide groove 130 extends along the circumferential direction D2 of the main body 10 .

In this embodiment, the main body 10 is a rotatable object (rotatable body), which can rotate relative to its own axis or a virtual rotation center axis. As shown in FIGS. 1 to 3 , the main body 10 can be a roller, which can rotate relative to its own axis for a certain period of time, and this stroke can be, for example, several turns, one turn, half a turn, or an arc path less than half a turn.

The film suction member 20 is, for example but not limited to, a suction nozzle, which is disposed on the outer peripheral surface 110 of the main body 10 . Specifically, the film material suction member 20 is accommodated in the through groove 120 of the main body 10 , and the film material suction member 20 can move along the radial direction D1 of the main body 10 . The movement of the film suction member 20 can be implemented through a driving mechanism (such as a cylinder or a stepper motor, not shown separately) inside or outside the main body 10 . A suction end 210 of the film material suction member 20 protrudes from the through groove 120 and is exposed to the outside, and the suction end 210 has a suction hole 211 extending along the radial direction D1 of the main body 10, which can be installed inside or outside the main body 10. The air suction device (such as a pump, not shown) is connected to suck the film through the air suction device and the suction hole 211 .

The film material clamping member 30 is movably disposed on the outer peripheral surface 110 of the main body 10 . In detail, the film material clamping member 30 includes two clamping units 310 , and each of the two clamping units 310 includes a connected main body 311 and a clamping end 312 . The main body 311 is respectively accommodated in the two guide grooves 130, and the respective clamping ends 312 of the clamping units 310 protrude from the guide grooves 130 and are exposed to the outside. The film material clamping member 30 can move along the circumferential direction D2 of the main body 10 to move the clamping end 312 away from or close to the film material suction member 20 . The film holding member 30 can be moved by a driving mechanism (such as a cylinder or a stepper motor, not shown separately) inside or outside the main body 10 . The number of guide grooves 130 and clamping units 310 described in this embodiment is for illustrative purposes only, and is not intended to limit the present invention.

The following describes how to use the film peeling device 1 to peel off the film. First, refer to Figures 4 and 5, which are schematic diagrams of the film peeling device in Figure 1 sucking up the film. The film suction member 20 can move back and forth relative to the main body 10 between the film suction position (Fig. 4) and the film peeling position (Fig. 5). When the film suction and pasting operation is not performed, the film material suction member 20 is normally maintained in the film peeling position.

The substrate 101 covered with the film (for example, ABF film) 100 is transported to the bottom of the film peeling device 1 . As shown in FIG. 4 , the film suction member 20 moves toward the substrate 101 and moves from the film peeling position to the film suction position. In the film suction position, the suction end 210 of the film material suction member 20 is relatively far away from the outer peripheral surface 110 of the main body 10 , and the suction hole 211 located at the suction end 210 touches the film 100 . When in the film suction position, the air suction device inside or outside the main body 10 can be activated to suck the film 100 through the suction end 210 .

As shown in FIG. 5 , after the film material suction part 20 sucks the film 100 , the film material suction part 20 moves in the reverse direction and the self-suction film position returns to the film peeling position. In the film peeling position, the suction end 210 of the film material suction member 20 is relatively close to the outer peripheral surface 110 of the main body 10 . The film suction part 20 moves upward along the radial direction D1 while moving from the film suction position to the film peeling position, and then lifts off a part of the film 100 . In this way, in addition to the suction force from the suction end 210 , the external force for lifting off the film 100 is also the positive pulling force generated by the movement of the film material suction part 20 along the radial direction D1 , making it easier to lift off the film 100 . The lifted-off portion of the film 100 is separated from the substrate 101 to form a gap G.

Next, please further refer to Figures 6 and 7, which are schematic diagrams of the film peeling device in Figure 1 clamping and pasting the film. As shown in Figures 4 and 5, when the operation of clamping and pasting the film 100 has not yet been performed, the film material clamping member 30 is normally in the standby position, and the two clamping ends 312 of the film material clamping member 30 are relatively far away from the film material suction member. 20.

As shown in FIG. 6 , the film material clamping member 30 moves along the circumferential direction D2 of the main body 10 and moves from the standby position to the clamping position. In the clamping position, the two clamping ends 312 are relatively close to the film material suction member 20 , and the suction hole 211 of the film material suction member 20 is between the two clamping ends 312 . During the process of moving from the standby position to the clamping position, the clamping end 312 of the film material clamping member 30 moves along the outer peripheral surface 110 and extends into the gap G to clamp the lifted part of the film 100 .

As shown in FIG. 7 , in this embodiment, the main body 311 and the clamping end 312 of the clamping unit 310 of the film material clamping member 30 are rigid structures, and can be extended along the circumferential direction D2 through the clamping end 312 After the gap G, the main body 311 rises vertically and drives the clamping end 312 to approach the outer peripheral surface 110, thereby clamping the film 100, but the invention is not limited thereto. In other embodiments, the clamping end 312 may be a metal elastic piece or a plastic elastic piece, and the film 100 is clamped by the elastic force of the clamping end 312 itself.

After completing the work of clamping the film 100 , keep the film material suction part 20 to continue to suck the film 100 and the film material clamping part 30 to clamp the film 100 , and rotate the main body 10 to tear off the remaining part of the film 100 from the substrate 101 . If the main body 10 continues to rotate, the torn off film 100 can be rolled up, thereby completing the film peeling operation.

8 and 9 are schematic diagrams of a film peeling device according to another embodiment of the present invention. In this embodiment, the film peeling device 1a includes two main bodies 10a and a plurality of film suction members 20. The number of the main body 10a and the film material suction member 20 is not used to limit the present invention. The specific structure, action and function of the film material suction part 20 can be referred to the film material suction part 20 in FIGS. 1 to 7 , and will not be described again here.

The two main bodies 10a are arranged side by side up and down, and each includes three narrow tube parts 120a with smaller radial dimensions and four wide tube parts 130a with larger radial dimensions. The number of the narrow tube portion 120a and the wide tube portion 130a is not used to limit the present invention. The narrow tube portion 120a of one main body 10a corresponds to the narrow tube portion 120a of the other main body 10a. Similarly, the wide barrel portion 130a of one body 10a corresponds to the wide barrel portion 130a of the other body 10a.

For each main body 10a, each narrow barrel portion 120a is between two wide barrel portions 130a. Furthermore, the narrow tube portions 120a and the wide tube portions 130a are staggered and juxtaposed. The film material suction members 20 are respectively movably disposed on the outer peripheral surfaces 110 of the narrow tube portions 120a.

In this embodiment, the substrate 101 with the film 100 on both upper and lower surfaces can be transported between the two main bodies 10a, and the film 100 and the substrate 101 are clamped through the wide tube portions 130a of the two main bodies 10a. The film material suction member 20 can move relative to the narrow tube portion 120a to suck the film 100. In this way, the film 100 can be peeled off at multiple positions by a plurality of film material suction members 20 , so that the force of peeling off the film 100 can be evenly distributed, thereby preventing the film 100 or the film material suction members 20 from damaging the circuit pattern on the surface of the substrate 101 or electronic devices.

In addition, in this embodiment, an additional film material clamping member can be provided at each narrow tube portion 120a to clamp the film 100 lifted off due to the film material suction member 20. The specific structure, action and function of the film material clamping member can be referred to the film material clamping member 30 in Figures 1 to 7, and will not be described again here.

The film material suction member 20 in FIG. 2 is movably accommodated in the through groove 120 of the main body 10, but the invention is not limited thereto. Figure 10 is a schematic diagram of a film peeling device according to yet another embodiment of the present invention. In this embodiment, the film peeling device 1b includes a main body 10b, a film material suction part 20b and a film material clamping part 30. The film material clamping member 30 is movably disposed on the main body 10. For its specific structure, operation, and function, reference can be made to the film material clamping member 30 in Figures 1 to 7, and will not be described again here.

In this embodiment, the film material suction member 20b is an air suction port located on the outer peripheral surface 110 of the main body 10b. That is to say, the main body 10b and the film material suction piece 20b are integrally formed. During the process of sucking and lifting off the film, the air suction port (film material suction part 20b) directly sucks air, so that the film is lifted off completely by relying on the suction force of the air suction port.

To sum up, the film peeling device disclosed according to the present invention includes a film material clamping member, which is movably disposed on the outer peripheral surface of the main body. After the film material suction part lifts off a part of the film from the base plate, the film material clamping part can hold the lifted part of the film, and then the film can be completely removed after the main body is rotated. The film material clamping piece can provide additional clamping force so that the peeled off part of the film can be fixed to the main body, which helps to make the removal of the film easier.

In addition, the film material suction part can be movably arranged on the main body, and the film material suction part can move along the radial direction of the main body. In this way, the external force for lifting off the film is not only the suction force from the film material suction part, but also the positive pulling force generated by the movement of the film material suction part in the radial direction, making it easier to lift off the film.

In addition, the main body may include a narrow tube part with a smaller radial dimension and a wide tube part with a larger radial dimension, and the film material suction part and/or the film material clamping part may be disposed at the narrow tube part. The film and substrate are clamped through the wide tube part, and the film material suction part can move relative to the narrow tube part to absorb the film. In this way, the film can be peeled off at multiple positions through multiple film material suction parts, so that the force of peeling off the film can be evenly distributed.

Although the present invention is disclosed in the foregoing embodiments, these embodiments are not intended to limit the present invention. All changes and modifications made without departing from the spirit and scope of the present invention shall fall within the scope of patent protection of the present invention.
