The drive is configured to drive the film-applying component to rotate. Along the rotation direction of the film-applying component, a plurality of air holes are spaced apart on the outer peripheral surface of the film-applying component. When the film-applying component rotates, it can at least partially press the protective film onto the workpiece, and the portion of the film-applying component that presses the protective film onto the workpiece is designated as a pressing region. The vacuum assembly communicates with the air holes located outside the pressing region. The cutting assembly is configured to cut off the portion of the protective film pressed onto the workpiece.

[0006] The mounting shaft is provided with an air passage, one end of which is connected to the air hole located outside the pressing area, and the other end of which is connected to the vacuuming component.

[0007] In one possible implementation, the outer peripheral surface of the mounting shaft abuts against the cavity wall of the first air chamber, and the air passage is recessed in the outer peripheral surface of the mounting shaft.

[0008] In one possible implementation, along the rotation direction of the film-applying component, the air passages are spaced apart on one side of the pressing area so that the air passages are isolated from the air holes on the pressing area.

[0009] In one possible implementation, the film-applying component includes a rotating part and an elastic part. The rotating part has a first air cavity inside it and is rotatably sleeved on the outer peripheral surface of the mounting shaft. The elastic part is sleeved on the outer peripheral surface of the rotating part.

[0023] The following description will refer to the accompanying drawings to provide a more complete picture of the present application. The drawings illustrate exemplary embodiments of the present application. However, the present application may be implemented in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. These exemplary embodiments are provided to make the present application thorough and complete, and to fully convey the scope of the present application to those skilled in the art. The same reference numerals denote the same or similar components.

[0024] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to limit the application. As used herein, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” are intended to also include the plural forms. Furthermore, when used herein, “comprising” and / or “including” and / or “having,” integers, steps, operations, components, and / or components, but does not exclude the presence or addition of one or more other features, regions, integers, steps, operations, components, and / or groups thereof.

[0025] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. Furthermore, unless expressly defined herein, terms such as those defined in a general dictionary should be interpreted as having the same meaning as they have in the relevant art and in the content of this application, and will not be interpreted as having an idealized or overly formal meaning.

[0026] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 3 As shown, this embodiment provides an automated film-applying device 100 for applying a protective film to a workpiece 1 transported to the film-applying position 2. The automated film-applying device 100 can apply the protective film to the product logo on the workpiece 1 to protect the product logo and prevent scratches during subsequent processing of the workpiece 1. Alternatively, the protective film can completely cover the surface of the workpiece 1 to protect its surface.

[0028] The automated film-applying device 100 includes a film supply assembly 20, a film-applying assembly 30, a vacuum assembly 40, and a cutting assembly 50. A protective film is wound onto the film supply assembly 20. The film-applying assembly 30 includes a rotation drive 31 and an applying member 32. One end of the protective film is wound onto the applying member 32. The drive is configured to drive the applying member 32 to rotate, and when the applying member 32 rotates, it can pull the protective film on the film supply assembly 20 to unwind. Along the rotation direction of the applying member 32, a plurality of air holes 320 are spaced apart on the outer peripheral surface of the applying member 32. When the applying member 32 rotates, it can at least partially press the protective film onto the workpiece 1, and the portion of the applying member 32 that presses the protective film onto the workpiece 1 is designated as a pressing region 3200. The vacuum assembly 40 connects to the air hole 320 located outside the pressing area 3200 to perform vacuum treatment on the air hole 320, so that the protective film wound on the film-applying member 32 can be attracted by the film-applying member 32 and smoothly pulled to move the protective film. The cutting assembly 50 is configured to cut the area of ​​the protective film pressed on the workpiece 1.

[0029] It is worth noting that the pressing area 3200 can be any part of the film-applying member 32. It simply means that at any given moment during the rotation of the film-applying member 32, the part where the film-applying member 32 presses the protective film onto the workpiece 1 is the pressing area 3200. Even if the film-applying member 32 continues to rotate, the position of the pressing area 3200 relative to the film-applying position 2 remains unchanged.

[0030] Thus, the automated film-applying device 100 of this application drives the film-applying component 32 to rotate via a drive unit. The film-applying component 32 can pull the protective film wound on the film supply assembly 20 to unwind, and then press the unwound protective film onto the workpiece 1. Subsequently, the cutting assembly 50 cuts off the portion of the protective film pressed onto the workpiece 1. Compared to the film-applying method of first cutting the pulled protective film, then grabbing the cut protective film and placing it on the workpiece 1 for pressing, the automated film-applying device 100 of this application can directly attach the pulled protective film to the workpiece 1 without the need for alignment and grabbing of the cut protective film, thus improving film-applying efficiency. In addition, the vacuum assembly 40 of this application only connects to the air hole 320 located outside the pressing area 3200 to adsorb the protective film not pressed onto the workpiece 1 onto the film-applying component 32, and the air hole 320 at the pressing area 3200 does not perform a vacuum operation to ensure that the cut protective film does not adsorb onto the film-applying component 32.

[0031] For ease of reading, this application introduces the terms first direction Y, second direction X, and third direction Z to describe embodiments of the application. The first direction Y, second direction X, and third direction Z can be three non-parallel straight lines in space; further, the first direction Y, second direction X, and third direction Z can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Y is described as the Y-axis direction of the three-dimensional coordinate system, the second direction X as the X-axis direction of the three-dimensional coordinate system, and the third direction Z as the Z-axis direction of the three-dimensional coordinate system.

[0032] Please combine Figure 1 and Figure 2 In one embodiment, the automated film application device 100 further includes a conveying component 60 configured to convey the workpiece 1 to the film application position 2.

[0033] In this embodiment, the conveying assembly 60 is a belt conveyor. The workpiece 1 can be placed on the conveying assembly 60 to be conveyed along the second direction X by the conveying assembly 60. The automated film-applying device 100 also includes a mounting frame 10. Along the third direction Z, the mounting frame 10 is located above the conveying assembly 60. The film-applying assembly 30 is connected to the mounting frame 10. The mounting frame 10 can be installed on the frame of the conveying assembly 60 or on a support frame or other structure provided outside the conveying assembly 60.

[0034] When the conveying assembly 60 transports the workpiece 1 to the film application position 2, the conveying assembly 60 stops working. At this time, the workpiece 1 is transported to the area directly below the film application component 32 of the film application assembly 30. The rotation drive 31 drives the film application component 32 to rotate, and the film application component 32 then presses the protective film wound on it onto the workpiece 1.

[0035] Please combine Figure 2 In one embodiment, the automated film application device 100 further includes a moving component 70 and a mounting plate 90. The moving component 70 is drively connected to the mounting plate 90 and is used to drive the mounting plate 90 to move at least along a second direction X and a third direction Z. The film application component 30 is connected to the mounting plate 90.

[0036] In this embodiment, the moving component 70 includes a lifting mechanism 71, a lifting plate 72, and a sliding mechanism 73. Along the first direction Y, the lifting mechanism 71 is connected to one side of the mounting frame 10. The lifting mechanism 71 is positioned along a third direction Z, and can be a linear reciprocating mechanism such as a cylinder slide or a lead screw slide. The lifting mechanism 71 is drive-connected to the lifting plate 72 to drive the lifting plate 72 to move up and down along the third direction Z. Along the first direction Y, the sliding mechanism 73 is connected to the side of the lifting plate 72 away from the mounting frame 10. The sliding mechanism 73 is along a second direction X, and can be a linear reciprocating mechanism such as a cylinder slide or a lead screw slide. Along the first direction Y, the mounting plate 90 is located on the side of the sliding mechanism 73 away from the lifting plate 72, and the sliding mechanism 73 is drive-connected to the mounting plate 90 to drive the mounting plate 90 to slide along the second direction X. Along the first direction Y, the film supply component 20 and the film application component 30 are connected to the side of the mounting plate 90 away from the lifting plate 72.

[0037] Thus, the lifting mechanism 71 in the moving assembly 70 can drive the film-applying assembly 30 to move up and down along the third direction Z, so that the film-applying element 32 of the film-applying assembly 30 approaches or moves away from the workpiece 1 transported by the conveying assembly 60. The sliding mechanism 73 in the moving assembly 70 can drive the film-applying assembly 30 to slide along the second direction X, so that the film-applying element 32 of the film-applying assembly 30 approaches or moves away from the cutting assembly 50, so that the cutting assembly 50 can cut off the portion of the protective film attached to the workpiece 1.

[0038] Please combine Figure 2 and Figure 3 In one embodiment, the film supply assembly 20 includes a rotating cylinder 21, which is rotatably connected to the side of the mounting plate 90 away from the lifting plate 72 along a first direction Y. The rotation axis of the rotating cylinder 21 is parallel to the first direction Y. The protective film is wound around the outer peripheral surface of the rotating cylinder 21. When the film applicator 32 rotates and pulls the protective film to move, the protective film drives the rotating cylinder 21 to rotate, thereby realizing the unwinding operation of the protective film.

[0039] In this embodiment, the vacuum assembly 40 includes a vacuuming component 41 and a mounting shaft 42. Along the first direction Y, the mounting shaft 42 is fixed to the side of the mounting plate 90 away from the lifting plate 72. The axis of the mounting shaft 42 is parallel to the first direction Y, and the mounting shaft 42 is located below the rotating cylinder 21 and in front of the rotating cylinder 21 along the conveying direction of the conveying assembly 60. The film-applying component 32 is sleeved on the outer peripheral surface of the mounting shaft 42, allowing the film-applying component 32 to rotate around the axis of the mounting shaft 42.

[0040] The mounting shaft 42 has a through hole 421 extending through it along the first direction Y. Along the first direction Y, the rotation drive 31 is mounted on the side of the mounting plate 90 near the lifting plate 72. The film application assembly 30 also includes a drive shaft 34, which is positioned along the first direction Y and passes through the through hole 421. One end of the drive shaft 34 is connected to the drive end of the rotation drive 31, and the other end of the drive shaft 34 extends out of the through hole 421 and is connected to the film application assembly 32, so that the rotation drive 31 drives the film application assembly 32 to rotate via the drive shaft 34.

[0041] Specifically, a bearing is provided between the mounting shaft 42 and the film-applying component 32 to reduce the frictional force when the film-applying component 32 rotates relative to the mounting shaft 42.

[0042] Please combine Figure 2 In one embodiment, the automated film applicator 100 further includes a pressing assembly 80. The pressing assembly 80 is located between the film applicator 32 and the film supply assembly 20, specifically located at the upper right of the film applicator 32.

[0043] The pressing assembly 80 includes a pressing seat 81, an adjusting plate 82, a pressing wheel 83, and an adjusting member 84. The pressing seat 81 is connected to the mounting plate 90, and the pressing seat 81 and the film-applying member 32 are located on the same side of the mounting plate 90. The adjusting plate 82 is slidably connected to the pressing seat 81, and the pressing wheel 83 is rotatably connected to the adjusting plate 82. The axis of the pressing wheel 83 is parallel to the first direction Y, and the pressing wheel 83 abuts against the protective film wound around the outer peripheral surface of the film-applying member 32, so that the protective film can fit more closely to the film-applying member 32.

[0044] The adjusting component 84 is a threaded component such as a bolt, and the adjusting component 84 is inclined. The pressing seat 81 has a threaded hole, and the adjusting component 84 is threadedly engaged with the threaded hole on the pressing seat 81. One end of the adjusting component 84 is connected to the adjusting plate 82, so that by rotating the adjusting component 84, the adjusting plate 82 can be driven to slide relative to the pressing seat 81, thereby adjusting the distance between the pressing roller 83 and the film-applying component 32.

[0045] Please combine Figures 2 to 5In one embodiment, the film-applying component 32 has a first air chamber 3211, and an air hole 320 communicates with the first air chamber 3211. The mounting shaft 42 is located inside the first air chamber 3211 so that the film-applying component 32 is sleeved on the outer peripheral surface of the mounting shaft 42. The mounting shaft 42 has an air passage 420. One end of the air passage 420 communicates with the air hole 320 located outside the pressing area 3200, and the other end of the air passage 420 communicates with a vacuum pump 41 so that the vacuum pump 41 performs a vacuuming operation on the air hole 320 outside the pressing area 3200 through the air passage 420. This allows the protective film to be adsorbed onto the outer peripheral surface of the film-applying component 32 in areas other than the pressing area 3200, so that when the film-applying component 32 rotates, the protective film adhered to it is pressed onto the workpiece 1.

[0046] In this embodiment, the film-applying component 32 includes a rotating part 321 and an elastic part 322. The rotating part 321 has the aforementioned first air cavity 3211, and the rotating part 321 is rotatably fitted onto the outer peripheral surface of the mounting shaft 42. One end of the drive shaft 34, which extends out of the through hole 421, enters the first air cavity 3211 and is connected to the rotating part 321, so as to drive the rotating part 321 to rotate. The elastic part 322 has a receiving groove 3222, and the rotating part 321 is located in the receiving groove 3222, so that the elastic part 322 is fitted onto the outer peripheral surface of the rotating part 321, and the protective film is wound around the outer peripheral surface of the elastic part 322. The elastic part 322 can be made of an elastic material such as rubber to avoid damage to the protective film.

[0047] Specifically, the outer peripheral surface of the rotating part 321 is provided with a snap-fit ​​groove 3212, the extending direction of which is parallel to the first direction Y. Multiple snap-fit ​​grooves 3212 are provided, spaced apart around the axis of the rotating part 321. The inner peripheral surface of the elastic part 322 is provided with multiple snap-fit ​​protrusions 3223, each corresponding to a snap-fit ​​groove 3212, and each protrusion 3223 is engaged within its corresponding snap-fit ​​groove 3212, so that the rotating part 321 can drive the elastic part 322 to rotate synchronously when it rotates.

[0048] In this embodiment, a first air hole 3210 is provided on the outer peripheral surface of the rotating part 321, and the first air hole 3210 is connected to the first air cavity 3211. A second air hole 3220 is provided on the outer peripheral surface of the elastic part 322, and the second air hole 3220 is connected to the receiving groove 3222. Furthermore, the second air holes 3220 are arranged in multiple rows, surrounding the axis of the elastic part 322. The multiple rows of second air holes 3220 are equally spaced, and each row of second air holes 3220 includes multiple second air holes 3220 spaced at intervals along the first direction Y. The number of first air holes 3210 is also multiple, and the multiple second air holes 3220 are correspondingly arranged with the multiple first air holes 3210, so that each second air hole 3220 is connected to the corresponding first air hole 3210 to form the aforementioned air hole 320.

[0049] In this embodiment, the outer peripheral surface of the mounting shaft 42 abuts against the cavity wall of the first air chamber 3211, thereby sealing the end of the first air hole 3210 that communicates with the first air chamber 3211 through the outer peripheral surface of the mounting shaft 42. The air passage 420 is recessed in the outer peripheral surface of the mounting shaft 42, thereby forming a certain space between the portion of the mounting shaft 42 where the air passage 420 is located and the cavity wall of the first air chamber 3211 for gas flow.

[0050] The mounting shaft 42 is provided with a second air chamber 422, which connects to the air passage 420 and the vacuum device. This allows the vacuum device to perform vacuuming operations on the air passage 420 through the second air chamber 422, and then perform vacuuming operations on the air hole 320 connected to the air passage 420. The vacuum assembly 40 also includes an air valve 43, which connects to the second air chamber 422 and the vacuum device to adjust the airflow or to turn it on or off.

[0051] Specifically, along the rotation direction of the film-applying component 32, air passages 420 are spaced apart on one side of the pressing area 3200 so that the air passages 420 are isolated from the air holes 320 on the pressing area 3200, thus preventing the vacuuming device from performing vacuuming operation on the air holes 320 on the pressing area 3200, which would cause the protective film pressed onto the workpiece 1 by the film-applying component 32 to be adsorbed by the film-applying component 32 and detached from the workpiece 1 after being cut.

[0052] After multiple tests and verifications, it was found that rotating the film applicator 32 by a quarter turn is sufficient to attach the protective film to the product label on the workpiece 1. Accordingly, along the rotation direction of the film applicator 32, taking the illustrated film applicator 32 as an example, the rotation direction of the film applicator 32 is counterclockwise, and the extension length of the air passage 420 is half the circumference of the cross-section of the mounting shaft 42. Simultaneously, one end of the air passage 420 corresponds to the position between the protective film wound on the film applicator 32 and the cut protective film, and the air passage 420 extends clockwise from this end.

[0053] Specifically, the film-applying assembly 30 also includes an angle detection element 33, which is used to detect the rotation angle of the drive shaft 34. After the rotation drive 31 drives the film-applying component 32 to rotate a quarter turn, the operation stops, waiting for the cutting assembly 50 to cut the protective film. Then, the rotation drive 31 continues to drive the film-applying component 32 to rotate. The angle detection element 33 can be a detection element such as an angle sensor, or it can achieve angle detection through a photoelectric sensor combined with a light-blocking structure.

[0054] Please combine Figure 2 In one embodiment, the cutting assembly 50 includes a cutting drive 51 and a cutting member 52. The cutting drive 51 is drively connected to the cutting member 52 and is used to drive the cutting member 52 to move along a first direction Y.

[0055] The cutting assembly 50 can be mounted on the frame of the conveying assembly 60 so that the position of the film application assembly 30 relative to the cutting assembly 50 changes as the film application assembly 30 moves with the mounting plate 90.

[0056] The cutting drive 51 can be a cylinder, etc., and the cutting element 52 can be a blade, etc. Along the second direction X, the cutting assembly 50 is located in front of the film-applying component 32. When the cutting drive 51 drives the cutting element 52 to move along the first direction Y, the cutting element 52 cuts off the area of ​​the protective film pressed on the workpiece 1.

[0057] Specifically, the outer peripheral surface of the elastic portion 322 of the film-applying component 32 is provided with a relief groove 3221, which extends along the first direction Y, and the cutting component 52 can move within the relief groove 3221. The number of relief grooves 3221 is set to four, and the four relief grooves 3221 are equally spaced.

[0058] In this embodiment, the moving component 70 further includes a first photoelectric sensor 74, a second photoelectric sensor 75, a third photoelectric sensor 76, and a light-blocking plate 91. Along the second direction X, the first photoelectric sensor 74, the second photoelectric sensor 75, and the third photoelectric sensor 76 are arranged sequentially at intervals, and along the conveying direction of the conveying component 60, the first photoelectric sensor 74 is located in front of the second photoelectric sensor 75. The light-blocking plate 91 is connected to the mounting plate 90 so that when the sliding mechanism 73 drives the mounting plate 90 to slide along the second direction X, the light-blocking plate 91 slides along the second direction X with the mounting plate 90, and passes through the first photoelectric sensor 74, the second photoelectric sensor 75, and the third photoelectric sensor 76. When the light-blocking plate 91 moves to the respective positions of the first photoelectric sensor 74, the second photoelectric sensor 75, and the third photoelectric sensor 76, it emits a position detection signal to locate the moving position of the film-applying component 32.

[0059] Thus, when the transport assembly moves the workpiece 1 to the film-applying position 2, the light-blocking sheet 91 is located at the position of the first photoelectric sensor 74. The lifting mechanism 71 drives the film-applying component 32 to descend until it contacts the workpiece 1, the rotation drive 31 drives the film-applying component 32 to rotate, and the sliding mechanism 73 drives the film-applying component 32 to move away from the cutting assembly 50 until the light-blocking sheet 91 triggers the second photoelectric sensor 75. During this movement, the film-applying component 32 applies the protective film wound on it to the workpiece 1. Subsequently, the sliding mechanism 73 drives the film-applying component 32 to continue moving away from the cutting assembly 50 until the light-blocking sheet 91 triggers the third photoelectric sensor 76. At this time, the cutting drive 51 drives the cutting component 52 to move along the first direction Y, thereby cutting off a portion of the protective film applied to the workpiece 1. Subsequently, the sliding mechanism 73 drives the film-applying component 32 to move closer to the cutting assembly 50 until the light-blocking sheet 91 triggers the first photoelectric sensor 74, and the lifting mechanism 71 drives the film-applying component 32 to rise to the initial position.

[0060] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
