Description

Technical Field

[0001] This utility model relates to the field of automatic film peeling technology, and in particular to a film peeling device and a film application equipment having the same. Background Technology

[0002] In related technologies, film-tearing devices include a clamping mechanism for holding one corner of the film to be torn, and a horizontal driver and a vertical driver for driving the clamping mechanism to move horizontally and vertically, respectively. When tearing the film from a product, the clamping mechanism can first be moved to one end of the length of the film to be torn by the horizontal and vertical drivers. Then, the clamping mechanism holds one end of the film to be torn, and the horizontal and vertical drivers drive the clamping mechanism to rise and move to the other end of the length of the film to be torn, thus completing the removal of the film. Although this type of film-tearing device has a simple structure, for films with large widths, since the clamps can only hold one side of the film in the width direction during tearing, the force on both sides of the film in the width direction is uneven. This not only easily leads to the film breaking during tearing, but also easily causes wrinkles in the adhesive film attached to the product and located below the film to be torn. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a film-tearing device that is applicable not only to the tearing of conventional narrow-width films but also to the tearing of wide-width films, thus having greater versatility.

[0004] This utility model also provides a film-applying device having the above-mentioned film-peeling device.

[0005] According to a first aspect embodiment of the present invention, a film-tearing device includes a lifting mechanism and two film-tearing modules. The lifting mechanism includes a lifting driver and a lifting frame. The lifting driver is connected to the lifting frame and is used to drive the lifting frame to lift. The two film-tearing modules are arranged opposite to each other on the lifting frame along a first horizontal direction. Each film-tearing module includes a clamping mechanism and a second horizontal driver. The second horizontal driver is connected to the clamping mechanism and is used to drive the clamping mechanism to move along a second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction. The clamping ends of the clamping mechanisms in the two film-tearing modules are opposite to each other and spaced apart.

[0006] The film-tearing device according to the first aspect of the present invention has at least the following beneficial effects:

[0007] The film-tearing device of this embodiment has two sets of film-tearing modules. Each set of film-tearing modules includes a clamping mechanism and a second horizontal driver. The clamping ends of the two sets of film-tearing modules are opposite and spaced apart in the first horizontal direction. Therefore, when it is necessary to tear a narrow film, the width direction of the film to be to be torn in the film product can be made parallel to the first horizontal direction and the length direction parallel to the second horizontal direction. Then, the clamping mechanism in one set of film-tearing modules is driven by the lifting driver and the second horizontal driver to the end of the film to be to be torn that protrudes from the film product in the second horizontal direction. Then, the clamping mechanism clamps the end of the film to be to be torn that protrudes from the film product. Then, the clamping mechanism is driven to rise and move to the other end of the film to be to be torn in the second horizontal direction by the second horizontal driver and the lifting driver, thus completing the tearing of the narrow film. When it is necessary to tear a wide film, the width direction of the film to be to be torn in the film product is first made parallel to the first horizontal direction and the length direction parallel to the second horizontal direction. The film is directed parallel to the first horizontal direction and parallel to the second horizontal direction in length. Then, a lifting driver and a second horizontal driver drive the clamping mechanisms in two sets of film-tearing modules to the end of the film to be peeled that protrudes from the product in the second horizontal direction. The two clamping mechanisms are positioned on opposite sides of the film's width direction. They then clamp the two sides of the film protruding from the product's width direction. Finally, the two second horizontal drivers and the lifting driver work together to drive the two clamping mechanisms to rise synchronously and move to the other end of the film in the second horizontal direction, thus completing the peeling of the wide film. Because the film is clamped on opposite sides of its length direction, the force on both sides of the film's width direction is more even during peeling, effectively reducing the risk of breakage and wrinkles in the film adhering to the product.

[0008] According to some embodiments of the first aspect of the present invention, the film-tearing device includes a clamping mechanism comprising a rotary driver and a clamping assembly. The rotary driver is connected to the driving end of a second horizontal driver and is connected to the clamping assembly, and is used to drive the clamping assembly to rotate about a rotation axis parallel to the first horizontal direction.

[0009] According to some embodiments of the first aspect of the present invention, the film-tearing device includes a clamping driver and two jaws. The clamping driver is connected to the two jaws and is used to drive the two jaws to move closer or further apart.

[0010] According to some embodiments of the first aspect of the present invention, the film-tearing device has two grippers symmetrically arranged about the rotation axis of the gripping assembly, and can move synchronously relative to each other or in opposite directions under the drive of the gripping driver.

[0011] According to some embodiments of the first aspect of the present invention, the film-tearing device has a clamping mechanism that is adjustablely connected to the drive end of the second horizontal driver along a first horizontal direction.

[0012] According to some embodiments of the first aspect of the present invention, in the film-tearing device, the driving end of the second horizontal driver is connected to an adjusting member, the adjusting member has an adjusting hole extending along the first horizontal direction, and the clamping mechanism is connected to the adjusting member by a fastener passing through the adjusting hole.

[0014] According to some embodiments of the first aspect of the present invention, in the film-tearing device, two film-tearing modules are both adjustablely connected to the lifting frame along a first horizontal direction.

[0015] According to some embodiments of the first aspect of the present invention, the film-tearing device further includes a mounting frame, a lifting drive is disposed on the mounting frame, a first position sensor and a second position sensor are disposed at intervals along the vertical direction on the mounting frame, a detection element is disposed on the lifting frame, the first position sensor and the second position sensor are electrically connected to the lifting drive, and the detection area of ​​the first position sensor or the second position sensor is located on the moving path of the detection element.

[0016] The film-applying device according to some embodiments of the second aspect of the present invention includes the film-removing device of the first aspect embodiment described above.

[0017] The film-applying device according to some embodiments of the second aspect of this utility model has at least the following beneficial effects:

[0018] By employing the film-peeling device of the first aspect embodiment described above, when the film is applied to the product and the film to be peeled off needs to be removed from the upper surface of the applied film, it can be applied to both conventional narrow-width film to be peeled off and wide-width film to be peeled off, making the film-applying equipment more versatile.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] The following is for reference only. Figure 1 To be continued Figure 2 This describes a film-tearing device according to a first aspect embodiment of the present invention.

[0030] Reference Figure 1According to some embodiments of the present invention, the film-removing device includes a lifting mechanism 10 and two film-removing modules 20; wherein, the lifting mechanism 10 is used to drive the film-removing modules 20 to move up and down, so that the film-removing modules 20 can approach or move away from the product after film application; it should be understood that the upper surface of the product after film application is sequentially attached from bottom to top with an application film 41 (e.g., a pressure-sensitive adhesive film) and a film to be removed 42 (e.g., a release film).

[0031] Understandably, referring to Figure 1 To facilitate the connection of the film-tearing module 20 and the driving of the film-tearing module 20 to move up and down, the lifting mechanism 10 includes a lifting driver 11 and a lifting frame 12. The lifting frame 12 is used to set the film-tearing module 20, while the lifting driver 11 is connected to the lifting frame 12 and is used to drive the lifting frame 12 to move the film-tearing module 20 up and down together.

[0032] Understandably, referring to Figure 1 Two film-tearing modules 20 are arranged opposite to each other on the lifting frame 12 along the first horizontal direction; wherein, each film-tearing module 20 includes a clamping mechanism 22 and a second horizontal driver 21. The second horizontal driver 21 is connected to the clamping mechanism 22 and is used to drive the clamping mechanism 22 to move along the second horizontal direction, which is perpendicular to the first horizontal direction. The clamping ends of the clamping mechanisms 22 in the two film-tearing modules 20 are opposite to each other and spaced apart.

[0033] It should be understood that, with the film-tearing device of this embodiment, when it is necessary to tear off the narrow film sheet 42, the width direction of the film sheet 42 to be torn can be made parallel to the first horizontal direction and the length direction parallel to the second horizontal direction. Then, the lifting driver 11 and the second horizontal driver 21 drive the clamping mechanism 22 in one of the film-tearing modules 20 to one end of the film sheet 42 protruding from the film product in the second horizontal direction. Then, the clamping mechanism 22 clamps the end of the film sheet 42 protruding from the film product. Then, the second horizontal driver 21 and the lifting driver 11 cooperate to drive the clamping mechanism 22 to rise and move to the other end of the film sheet 42 in the second horizontal direction to complete the tearing of the narrow film sheet 42.

[0034] When it is necessary to remove the wide film sheet 42, the width direction of the film sheet 42 in the film-applied product is first made parallel to the first horizontal direction and the length direction is parallel to the second horizontal direction. Then, the lifting driver 11 and the second horizontal driver 21 drive the clamping mechanisms 22 in the two sets of film-tearing modules 20 to the end of the film sheet 42 protruding from the film-applied product in the second horizontal direction, so that the two clamping mechanisms 22 are respectively corresponding to the two sides of the width direction of the film sheet 42. Then, the two clamping mechanisms 22 respectively clamp the width of the film sheet 42 protruding from the film-applied product. The two clamping mechanisms 22 are then driven to rise synchronously and move to the other end of the film to be peeled 42 in the second horizontal direction through the cooperation of two second horizontal drivers 21 and lifting drivers 11, thus completing the peeling of the wide film to be peeled 42. Since the two opposite sides of one end of the wide film to be peeled 42 in the length direction are clamped by the clamping mechanisms 22, the force on both sides of the width direction of the film to be peeled 42 will be more uniform during the peeling process, thereby effectively reducing the risk of the film to be peeled 42 breaking during the peeling process and the risk of wrinkles appearing on the product mounting film 41.

[0035] Understandably, referring to Figure 1 In some embodiments, the lifting frame 12 includes a vertical frame 121 extending in a vertical direction and a horizontal frame 122 extending in a second horizontal direction. The vertical frame 121 is connected to the drive end of the lifting driver 11, and the film-peeling modules 20 are all disposed on the horizontal frame 122, so that the clamping mechanism 22 can have a large travel in the second horizontal direction. The middle part of the horizontal frame 122 is connected to the lower end of the vertical frame 121 to better ensure the stability of the film-peeling device during operation. At the same time, in order to avoid interference between the horizontal frame 122 and the film-applied product, which would affect the normal film peeling, the clamping mechanism 22 is disposed below the horizontal frame 122.

[0036] Understandably, referring to Figure 1 In some embodiments, the lifting driver 11 and the second horizontal driver 21 are both selected to be linear motor modules, so that the control of the film tearing speed and the corresponding film tearing stroke during the film tearing process will be more precise. It should be understood that in other embodiments, the lifting driver 11 and the second horizontal driver 21 may also be selected to be other types of linear drive devices such as cylinders and electric push rods, without specific limitations.

[0037] Understandably, referring to Figure 2In some embodiments, the clamping mechanism 22 includes a rotary driver 221 and a clamping assembly 222. The clamping end of the clamping mechanism 22 is formed on the side of the clamping assembly 222 opposite to the rotary driver 221. The rotary driver 221 is connected to the driving end of the second horizontal driver 21 and is connected to the clamping assembly 222, and is used to drive the clamping assembly 222 to rotate about a rotation axis parallel to the first horizontal direction. With the above structure, after the clamping mechanism 22 clamps one end of the film to be peeled 42, the rotary driver 221 can first drive the clamping assembly 222 to rotate a certain angle, so as to drive one end of the film to be peeled 42 to tilt upward first, so as to avoid the second horizontal driver 21 and the lifting driver 11 driving the clamping mechanism 22 to move the clamped end of the film to be peeled 42 and causing the film 41 attached to the product to be pulled during the subsequent movement of the clamped end of the film 42 by the second horizontal driver 21 and the lifting driver 11, thereby reducing the risk of wrinkles on the film 41.

[0038] It is understood that, in one embodiment, reference is made to... Figure 2 The clamping assembly 222 includes a clamping driver 223 and two jaws 224. The two jaws 224 form the clamping end of the clamping mechanism 22 for clamping the film to be torn 42 during the film tearing process. The clamping driver 223 is connected to the two jaws 224 and is used to drive the two jaws 224 to move closer or further apart. When the two jaws 224 move closer together, they can clamp the film to be torn 42 between them. When the two jaws 224 move further apart, they can release the film to be torn 42. Meanwhile, to avoid collisions or friction between the grippers 224 and the mounting film 41 during the rotation of the clamping assembly 222 driven by the rotary driver 221, which could lead to wrinkles on the mounting film 41, the two grippers 224 are symmetrically arranged about the rotation axis of the clamping assembly 222. They can move synchronously relative to each other or in opposite directions under the drive of the clamping driver 223. This minimizes the distance between the two grippers 224 and the rotation axis of the clamping assembly 222 when the clamping assembly 222 is holding the film to be peeled 42. Consequently, the required rotation radius of the two grippers 224 is also minimized when the clamping assembly 222 rotates under the drive of the rotary driver 221. This also reduces the risk of the grippers 224 colliding or rubbing against the mounting film 41 during rotation, even when the length of the end of the film to be peeled 42 protruding from the mounting film 41 is short, further improving the problem of wrinkles on the mounting film 41.

[0039] It is understood that in some embodiments, the clamping mechanism 22 is adjustablely connected to the drive end of the second horizontal driver 21 along the first horizontal direction, so that when tearing a wide film sheet 42, the spacing between the clamping mechanisms 22 in the two film tearing modules 20 can be adjusted according to the width of the film sheet 42, thereby further improving the versatility of the film tearing device. For example, in one embodiment, referring to... Figure 1 The driving end of the second horizontal driver 21 is connected to an adjusting member 23. The adjusting member 23 has an adjusting hole 231 extending along the first horizontal direction. The clamping mechanism 22 is connected to the first adjusting member 23 via a fastener passing through the adjusting hole 231. By loosening the fastener, the clamping mechanism 22 can slide along the first horizontal direction, allowing the distance between the clamping ends of the two clamping mechanisms 22 to adapt to the width of the film to be torn 42, thus better clamping both sides of the film to be torn 42 in the width direction. Furthermore, referring to… Figure 1 Specifically, the adjusting member 23 includes a connecting section 232 and an adjusting section 233. The connecting section 232 extends vertically and its upper end is connected to the driving end of the second horizontal driver 21. The adjusting section 233 is connected to the lower end of the connecting section 232, and an adjusting hole 231 is provided on the adjusting section 233. That is, the clamping mechanism 22 is connected to the adjusting section 233, so that the clamping mechanism 22 can be suspended below the horizontal frame 122. In addition, in order to increase the upper limit of the width of the film to be torn 42 that the film tearing device can adapt to, one end of the adjusting section 233 is connected to the lower end of the connecting section 232, and the other end extends in the first horizontal direction away from the other film tearing module 20.

[0040] It should be understood that, in order to adjust the spacing between the clamping mechanisms 22 in the two film-tearing modules 20 according to the width of the film to be peeled 42, in some other embodiments, the two film-tearing modules 20 may be configured to be adjustablely connected to the lifting frame 12 along the first horizontal direction. For example, in one embodiment, two opposing and adjustable adjustment seats may be provided on the horizontal frame 122, and the two second horizontal actuators 21 in the two film-tearing modules 20 may be respectively provided on the two adjustment seats. Similarly, the adjustment seats may be provided with adjustment holes 231 extending along the first horizontal direction, and the adjustment seats may be connected to the horizontal frame 122 by fasteners passing through the adjustment holes 231.

[0041] It is understandable that, in order to fix the film-peeling device above the film-applying station in the product film-applying equipment, in some embodiments, reference is made to... Figure 1The film-peeling device also includes a mounting frame 30, which can be mounted and fixed to the frame or other structure of the film-applying equipment. The lifting drive 11 in the lifting mechanism 10 is mounted on the mounting frame 30. To control the lower and upper limits of the film-peeling mechanism's stroke, the mounting frame 30 is equipped with a first position sensor 31 and a second position sensor 32 spaced vertically. The first and second position sensors 31 and 32 are electrically connected to the lifting drive 11. A detection element (not shown in the figures) is correspondingly mounted on the lifting frame 12, and the detection area of ​​the first or second position sensor 32 is located on the movement path of the detection element. Thus, when the lifting frame 12 descends to the detection area of ​​the second position sensor 32, it can be sensed by the second position sensor 32, thereby controlling the lifting drive 11 to stop driving the lifting frame 12 to continue descending; and when the lifting frame 12 ascends to the detection area of ​​the first position sensor 31, it can be sensed by the first position sensor 31, thereby controlling the lifting drive 11 to stop driving the lifting frame 12 to continue ascending.

[0042] The following describes a film-applying device according to a second aspect of the present invention. The film-applying device of this embodiment includes the film-removing device described in the first aspect of the present invention.

[0043] It should be understood that by adopting the film-peeling device of the first aspect embodiment described above, when the film of the product is applied and the film to be peeled off needs to be peeled off from the upper surface of the applied film 41, it can be applied to both the peeling of conventional narrow-width film to be peeled off and the peeling of wide-width film to be peeled off, making the film-applying equipment more versatile.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
