[0019] Compared with the prior art, the present utility model has the following advantages:
[0020] For the film cutting device of the present utility model, by providing a film cutting mechanism, a film static elimination mechanism and a dust removal mechanism on the frame, and making the film static elimination mechanism and the dust removal mechanism be located downstream of the cutting mechanism in sequence, and enabling the film static elimination mechanism and the dust removal mechanism to move along the conveying direction of the film together with the film cutting mechanism, so that during the film conveying process and the film cutting process, the film can be statically eliminated and dust removed, reducing the situations of coiling and adhesion caused by static electricity, effectively removing impurities and external pollutants adsorbed on the film, thereby ensuring the smooth cutting of the film and the cutting quality of the film, and having a good use effect.
[0021] In addition, the mounting bracket provided on the frame can provide a mounting space for the static eliminator and the dust remover, and integrating the static eliminator and the dust remover on the same mounting bracket can make the structure more compact. Moreover, the cutting knife can not only move along the conveying direction of the plastic film, but also move orthogonally to the conveying direction of the plastic film, and can also lift relative to the mounting bracket, so that it is convenient to cut the plastic film into a preset shape.
[0022] Secondly, the static eliminator is located above the plastic film, which is beneficial to eliminating static electricity from the plastic film and can effectively prevent the plastic film from accumulating static electricity due to friction or environmental influence during use, resulting in adhesion between the plastic films. The distance between the static eliminator and the plastic film is adjustable, which is not only beneficial to improving the static elimination effect, but also can be used for static elimination of plastic films with different thicknesses, improving the universality of use. The dust remover is located above the plastic film, which is convenient for removing dust from the plastic film.

Their technologies are mature, convenient for design and implementation, and respectively have good static elimination effects and dust removal effects. The setting of the distance between the static eliminator and the dust remover, as well as the setting of the minimum distance between the static eliminator and the plastic film and the setting of the distance between the dust remover and the plastic film, can further improve the static elimination effect and dust removal effect on the plastic film.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood in combination with specific situations.
[0034] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0035] This embodiment relates to a film cutting device, which can ensure the smooth cutting and cutting quality of the film.
[0036] In terms of the overall composition, asFigures 1 to 3 As shown in the figure, the film cutting setup of this embodiment includes a frame 1, on which a first displacement mechanism 11 is provided along the film conveying direction, and a film cutting mechanism 103, a film static elimination mechanism, and a dust removal mechanism are provided on the first displacement mechanism 11. Among them, the film cutting mechanism 103 has a cutting knife 15 for cutting the film 10 into a preset shape. The film static elimination mechanism and the dust removal mechanism are sequentially arranged downstream of the film cutting mechanism and can move along the film conveying direction with the film cutting mechanism 103. The film static elimination mechanism has a static elimination part 3 for eliminating static electricity from the film 10, and the dust removal mechanism has a dust removal part 4 for removing dust from the film 10.
[0037] At this time, in the above structure, by sequentially arranging the film cutting mechanism 103, the film static elimination mechanism, and the dust removal mechanism on the frame 1 along the film conveying direction, and enabling the film static elimination mechanism and the dust removal mechanism to move along the film conveying direction with the film cutting mechanism 103, static electricity can be eliminated and dust can be removed from the film 10 during both the conveying process and the cutting process of the film 10, so as to reduce the situations of coiling and adhesion caused by static electricity. The static elimination part can also remove the dust particles adsorbed on the film 10 due to static electricity, and then dust is removed through the dust removal part. Moreover, impurities and external pollutants adsorbed on the film 10 can be effectively removed, thereby ensuring the smooth cutting of the film 10 and the cutting quality of the film 10.
[0038] Specifically, continue to refer to Figures 1 to 3 As shown in the figure, in this embodiment, a loading mechanism 102 for conveying the film 10 is provided on the frame 1. The loading mechanism 102 can intermittently convey the film 10 in the wound state to the cutting station. Specifically, the loading mechanism 102 can refer to the structure in the prior art. The loading mechanism 102 adopts a conveyor belt mechanism, and the belt surface is a felt surface to prevent the film from slipping or moving. In addition, in this embodiment, a pressure roller 101 pressing on the film 10 is also provided on the frame 1. The axial direction of the pressure roller 101 is set orthogonally to the film conveying direction, and the pressure roller 101 can flatten the film 10 to prevent the unevenness of the film 10 conveyed to the cutting station from affecting the cutting quality of the film 10.
[0039] As a preferred embodiment, in this embodiment, an installation frame 2 is provided on the movable end of the first displacement mechanism 11. The static elimination part in the film static elimination mechanism and the dust removal part 4 in the dust removal mechanism are sequentially arranged on the installation frame 2. The installation frame 2 serves as a carrier. At this time, the setting of the installation frame 2 can provide an installation space for the static elimination part 3 and the dust removal part 4, and integrating the static elimination part 3 and the dust removal part 4 on the same installation frame 2 makes the structure more compact, and ensures that it can be displaced synchronously with the film cutting mechanism in the film conveying direction for real-time static elimination and dust removal.
[0040] In the film cutting mechanism 103 of this embodiment, in terms of structure, the film cutting mechanism 103 includes a second displacement mechanism 12 disposed on the movable end of the first displacement mechanism 11 and a lifting mechanism 13 disposed on the movable end of the second displacement mechanism 12. A cutting knife 15 is installed on the lifting mechanism 13. The moving direction of the second displacement mechanism 12 is perpendicular to the film conveying direction, and the second displacement mechanism 12 is horizontally disposed above the film.
[0041] Specifically, in this embodiment, the cutting knife 15 can move along the film conveying direction through the first displacement mechanism 11, can move along a direction orthogonal to the film conveying direction through the second displacement mechanism 12, and the cutting knife 15 can be lifted or lowered along the height direction of the mounting frame 2 through the lifting mechanism 13 to approach or move away from the film. This enables the cutting knife 15 to not only move along the film conveying direction, but also move along a direction orthogonal to the film conveying direction, and at the same time can be lifted or lowered relative to the mounting frame 2. In this way, the cutting knife 15 can move in multiple directions, facilitating the cutting knife 15 to cut the film into a preset shape.
[0042] It should be noted that in this embodiment, the film conveying direction specifically refers to the length direction of the frame 1, the direction orthogonal to the film conveying direction specifically refers to the width direction of the frame 1, and the height direction of the mounting frame 2 is also the height direction of the frame 1. Of course, it can be understood that the film conveying direction can also be along the width direction of the frame 1, then the direction orthogonal to the film conveying is along the length direction of the frame 1. It also should be noted that in this embodiment, the preset shape can be, for example, a rectangular sheet, a circular sheet, an oval sheet or other shapes.
[0043] In this embodiment, the second displacement mechanism 12 can be directly arranged on the first displacement mechanism 11. Of course, as a feasible implementation manner, the second displacement mechanism 12 can also be arranged on the mounting frame 2, so that the second displacement mechanism 12 can also move along the film conveying direction through the mounting frame 2 with the first displacement mechanism 12. Refer to Figure 1 and Figure 3 As shown, there are two mounting frames 2 arranged at intervals along the direction orthogonal to the film conveying direction. Each mounting frame 2 has a vertically arranged first connecting beam and a horizontally arranged second connecting beam. The first connecting beam and the second connecting beam are connected together, and the first connecting beam is connected to the first displacement mechanism 12. The second displacement mechanism 12 is arranged on the first connecting beam, and the static eliminator 3 and the dust removing member 4 are arranged on the second connecting beam.
[0044] Continue to refer to Figure 1 and Figure 3As shown, a lifting mechanism 13 is provided at the movable end of the second displacement mechanism 12, and a cutting knife 15 is provided at the lifting end of the lifting mechanism 13. In this way, the cutting knife 15 can move orthogonally to the conveying direction of the adhesive film and can also move up and down in the height direction of the mounting bracket 2. Among them, the first displacement mechanism 11 and the second displacement mechanism 12 can adopt linear modules, for example, and the lifting mechanism 13 can adopt an electric cylinder or an oil cylinder, for example.
[0045] In addition, the adhesive film cutting mechanism 103 further includes a rotating mechanism 14. The cutting knife 15 of this embodiment can rotate around the axis in the height direction of the frame 1, so as to be able to switch the orientation of the cutting knife 15. Specifically, during implementation, the rotating mechanism 14 can be provided at the power output end of the lifting mechanism 13, and the cutting knife 15 is installed at the power output end of the rotating mechanism 14. Among them, the rotating mechanism 14 adopts a motor, for example.
[0046] During specific cutting, the cutting knife 15 is driven by the first displacement mechanism 11 to move from the first position to the second position, and moves downward under the action of the lifting mechanism 13 to approach the adhesive film 10, and then moves orthogonally to the conveying direction of the adhesive film under the drive of the second displacement mechanism 12 to cut the first side of the adhesive film 10. Then the cutting knife 15 moves upward under the action of the lifting mechanism 13, rotates a certain angle under the rotating mechanism 14, then moves downward under the action of the lifting mechanism 13, and then moves along the conveying direction of the adhesive film under the drive of the first displacement mechanism 11 to cut the second side of the adhesive film 10.
[0047] Then, the cutting knife 15 moves upward under the action of the lifting mechanism 13 and moves a preset distance under the drive of the second displacement mechanism 12. At this time, the cutting knife 15 moves downward under the action of the lifting mechanism 13, and then cuts the third side of the adhesive film 10 under the drive of the second displacement mechanism 12. Then, the cutting knife 15 moves upward under the action of the lifting mechanism 13, rotates a certain angle under the rotating mechanism 14, then moves downward under the action of the lifting mechanism 13, and then moves along the conveying direction of the adhesive film under the drive of the first displacement mechanism 11 to cut the fourth side of the adhesive film 10. The first side, the second side, the third side and the fourth side enclose a rectangle, that is, the cut adhesive film 10 has a rectangular sheet structure, as Figure 1 shown by the area D in the dotted line box.
[0048] See Figures 1 to 3 As shown, in this embodiment, the static eliminator 3 is located above the adhesive film 10, and the distance between the static eliminator 3 and the adhesive film 10 is adjustable. At this time, the static eliminator 3 is located above the adhesive film, which is beneficial to eliminate static electricity from the adhesive film 10 and can effectively prevent the adhesive film from accumulating static electricity due to friction or environmental influence during use, resulting in adhesion of the adhesive film 10. The adjustable distance between the static eliminator 3 and the adhesive film 10 is not only beneficial to improving the static elimination effect, but also can be used for static elimination of adhesive films 10 with different thicknesses, improving the universality of use.
[0049] Moreover, the dust removing member 4 is also located above the adhesive film 10, and the distance between the dust removing member 4 and the adhesive film 10 is adjustable. Placing the dust removing member 4 above the adhesive film 10 facilitates dust removal of the adhesive film 10. The adjustable distance between the dust removing member 4 and the adhesive film 10 can not only improve the dust removal effect, but also be applicable to the dust removal of adhesive films 10 with different thicknesses, thus improving the universality of use.
[0050] It should be noted that, in addition to the distances between the static eliminator 3 and the dust removing member 4 and the adhesive film 10 being adjustable, it is also possible to only set the distance between the static eliminator 3 and the adhesive film 10 to be adjustable, or only set the distance between the dust removing member 4 and the adhesive film 10 to be adjustable, and this is also acceptable.
[0051] As a preferred embodiment, in this embodiment, a lifting assembly 21 is provided on the mounting frame 2, and both the static eliminator 3 and the dust removing member 4 are arranged on the lifting assembly 21. Thus, by the lifting of the lifting assembly 21, the synchronous lifting of the static eliminator 3 and the dust removing member 4 can be achieved, and it is also beneficial to save the number of arrangements of the lifting assembly 21. Specifically in implementation, the lifting assembly 21 can adopt, for example, a linear module or a cylinder, etc. By the drive of the lifting assembly 21, the static eliminator 3 and the dust removing member 4 are moved closer to or farther away from the adhesive film 10 to adjust the distances between the static eliminator 3 and the adhesive film 10 and between the dust removing member 4 and the adhesive film 10.
[0052] In this embodiment, the static eliminator 3 is preferably an electrostatic bar, and the axial direction of the electrostatic bar is arranged orthogonally to the conveying direction of the adhesive film. Specifically, the electrostatic bar is installed on the mounting frame 2, and preferably, the minimum distance L1 between the static eliminator 3 and the adhesive film 10 satisfies: 40mm ≤ L1 ≤ 60mm, that is, the distance L1 between the lowest position of the outer peripheral surface of the electrostatic bar and the adhesive film 10 is between 40mm and 60mm. Specifically in implementation, the distance L2 can be set to, for example, 40mm, 45mm, 50mm, 55mm or 60mm, etc., and preferably 50mm. In this way, the static elimination effect of the electrostatic bar can be further improved, and since the static eliminator 3 adopts an electrostatic bar, its technology is mature and it is also convenient for design and implementation.
[0053] The dust removing member 4 of this embodiment includes a suction air knife arranged on the mounting frame 2, and the air outlet of the suction air knife faces the adhesive film 10. Preferably, the suction air knife is arranged in parallel with the electrostatic bar, and the adsorption port of the suction air knife and the lowest position of the electrostatic bar are on the same horizontal plane. At this time, the dust removing member 4 adopts a suction air knife, its technology is mature, it is convenient for design and implementation, and it also has a good dust removal effect. It should be noted here that the negative pressure device and the negative pressure pipeline connected to the suction air knife can refer to the existing technology to be able to use the suction air knife to perform better dust removal on the adhesive film 10.
[0054] As a preferred embodiment, in this embodiment, the distance L2 between the dust removal member 4 and the film 10 satisfies: 40 mm ≤ L2 ≤ 60 mm, that is, the distance between the suction air knife and the film 10 is between 40 mm and 60 mm. Specifically in implementation, the distance L2 can be set to, for example, 40 mm, 45 mm, 50 mm, 55 mm or 60 mm, etc., preferably 50 mm. In this way, the dust removal effect of the suction air knife can be further improved, and the dust removal member 4 uses a suction air knife, which has mature technology and is also convenient for design and implementation.
[0055] It should be noted that when adjusting the distance between the static electricity bar and the film 10 and the distance between the suction air knife and the film 10, it is necessary to ensure that the lowest position of the static electricity bar and the adsorption port of the suction air knife are on the same horizontal plane, so that static electricity removal and dust removal can be better carried out.
[0056] On the basis that the static electricity removal member 3 and the dust removal member 4 are arranged on the same lifting assembly 21, preferably, the distance L between the static electricity removal member 3 and the dust removal member 4 in the film conveying direction satisfies: 40 mm ≤ L ≤ 60 mm, that is, the distance between the static electricity bar and the suction air knife in the film conveying direction is between 40 mm and 60 mm. Specifically in implementation, the distance L can be set to, for example, 40 mm, 45 mm, 50 mm, 55 mm or 60 mm, etc., preferably 50 mm. In this way, the static electricity removal effect of the static electricity bar and the dust removal effect of the suction air knife can be further improved.
[0057] The film cutting device of this embodiment further includes a film grabbing mechanism 105 located downstream of the dust removal mechanism. This grabbing mechanism is used to grab the cut film 10 to a preset position, so as to facilitate the blanking of the cut film 10 and is also beneficial to the subsequent cutting process of the film 10.
[0058] Specifically, still referring to Figures 1 to 3 As shown, in this embodiment, a cross beam 104 is provided on the frame 1 and arranged orthogonally to the film conveying direction. The film grabbing mechanism 105 includes a plurality of grabbing units slidably arranged on the cross beam 104, and each grabbing unit has an adsorption port 1050 for adsorbing the cut film 10. By providing the cross beam 104 on the frame 1, an installation basis can be provided for the film grabbing mechanism 105, and it is also beneficial to provide an installation basis for the detection device described below. And by using the adsorption port 1050 on the grabbing unit, the cut film 10 can be grabbed more firmly through negative pressure adsorption, and it can also prevent damage to the film 10 during the blanking process.
[0059] It should be noted that, in addition to the above structural form, the film grabbing mechanism 105 may not be provided with the cross beam 104, and a manipulator may be directly used to grab the cut film 10. In this case, the subsequent detection device needs to re-design the installation points on the frame 1. In addition, the grabbing unit may adopt a negative pressure suction nozzle in the prior art, and the suction port 1050 is arranged on the negative pressure suction nozzle. In this way, the negative pressure suction nozzle can be used to adsorb the film 10 to realize the grabbing of the film 10 and improve the stability of the film 10 adsorption. At this time, the number of the negative pressure suction nozzles arranged may be multiple in an array layout to further improve the stability of the film 10 adsorption.
[0060] As a preferred embodiment, in this embodiment, a detection device is also provided on the frame 1, and the detection device can detect the size of the cut film 10. Such a setting is beneficial to ensuring the quality of the cut film 10 and further improving the stability of chip packaging.
[0061] Specifically, the detection device includes a CCD camera 5. It has the characteristics of mature technology and high detection accuracy, which is beneficial to improving the detection accuracy of the cutting size of the film 10. As a relatively optimal embodiment, in this embodiment, the CCD camera 5 is preferably arranged on the cross beam 104 and specifically above the middle of the cut film 10, so as to better collect images of the cut film 10 and improve the detection accuracy of the cutting size. Moreover, integrating the CCD camera 5 and the grabbing unit on the cross beam 104 can also make the structure more compact.
[0062] It is worth noting that the detection device of this embodiment further includes a controller connected to the CCD camera 5, and the controller can adopt the existing mature technology. It is also worth noting that in addition to using the CCD camera 5 to detect the size of the cut film, the detection device can also adopt an infrared ranging device, etc., which is also acceptable.
[0063] In the film cutting device of this embodiment, by setting that the film static elimination mechanism and the dust removal mechanism can move along the film conveying direction with the film cutting mechanism 103, static elimination and dust removal can be performed on the film 10 during both the film 10 conveying process and the film 10 cutting process, reducing the situations of coiling and adhesion caused by static electricity, effectively removing impurities and external pollutants adsorbed on the film 10, thereby ensuring the smooth cutting of the film 10 and the cutting quality of the film 10, and having a good use effect.
[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
