[0095] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0096] Please see Figure 1For some L-shaped workpieces 200, a film 300 needs to be applied to the first surface 210 and the second surface 220 of the workpiece 200. The film 300 includes a main body 310 covering the first surface 210 and an end 320 extending out of the workpiece 200. Currently, the film 300 is usually applied manually by the operator based on personal skills, experience and work methods. However, this method is prone to various defects such as film bubbles, misalignment, wrinkles and damage.

[0097] To address at least one of the aforementioned problems, this application provides a film application device 100. Please refer to [link to relevant documentation]. Figure 2 It includes a carrier component 10, a film pressing component 20, and a film folding component 30.

[0098] The support assembly 10 is used to support the workpiece 200 and the membrane 300 disposed on the workpiece 200. The film pressing assembly 20 includes a film pressing body 21 and a film pressing part 231. Figure 4 (As shown). The folding assembly 30 includes a folding body 31 and a folding element 32 movably connected to the folding body 31. Figure 6 (As shown). The film pressing body 21 and the folding body 31 can be selectively attached to the support assembly 10. When the film pressing body 21 is attached to the support assembly 10, the film pressing portion 231 is adapted to press the main body portion 310 against the first surface 210. When the folding body 31 is attached to the support assembly 10, the folding member 32 can move in a first direction and abut against the end portion 320 to fold the end portion 320 towards the second surface 220. The folding member 32 can also move relative to the folding body 31 in a second direction to press the folded end portion 320 against the second surface 220. In this embodiment, the first direction is the Z-axis direction, and the second direction is the X-axis direction.

[0099] The aforementioned film-applying device 100 first carries the workpiece 200 and the film 300 disposed on the first surface 210 of the workpiece 200 via the support component 10. Then, the film-pressing body 21 is attached to the support component 10, and the film-pressing part 231 can press the main body 310 to the first surface 210, ensuring that the film 300 and the surface of the workpiece 200 are completely adhered without bubbles or damage. Next, the film-pressing body 21 is removed, and the film-folding body 31 is attached to the support component 10. The film-folding member 32 can move in the first direction and abut against the end 320 to fold the end 320 toward the second surface 220. Then, the film-folding member 32 moves relative to the film-folding body 31 in the second direction to press the folded end 320 to the second surface 220, thus completing the film application 300. This ensures that the film adheres firmly and neatly to the workpiece 200, and can simultaneously apply the film 300 to the surfaces of multiple workpieces 200, with high film application quality.

[0100] In this application, the function of the film pressing assembly 20 is to press the main body 310 of the film 300 onto the first surface 210 of the workpiece 200. It can be understood that this action can be achieved by applying force to the workpiece 200 through a portion of the film pressing assembly 20 adhering to the main body 310. This "portion" can be a fixed part relative to the film pressing assembly 20, applying force to the film 300 with the aid of the film pressing assembly 20, or it can be a movable part of the film pressing assembly 20, performing the application of force and film pressing during movement. Neither of these methods affects the achievement of the invention's objective. This application also provides more specific illustrative embodiments, which can be referred to in the following description and accompanying drawings.

[0101] Please see Figure 3 and Figure 4 In some embodiments, the film pressing assembly 20 further includes a sliding member 22 and a film pressing member 23. The sliding member 22 is generally plate-shaped and slidably disposed on the film pressing body 21. The film pressing member 23 includes a film pressing portion 231 and is connected to the sliding member 22. In some embodiments, the film pressing member 23 and the sliding member 22 are fixedly connected. In some embodiments, the film pressing member 23 and the sliding member 22 are movably connected. For example, when the film pressing body 21 is attached to the support assembly 10, the film pressing member 23 is connected to the sliding member 22 and can elastically move relative to the sliding member 22 in a first direction. The sliding member 22 can slide on the film pressing body 21 and drive the film pressing portion 231 to move so as to press the main body 310 onto the first surface 210. In this embodiment, a sliding push block 24 is also protruding from the upper surface of the sliding member 22 to drive the sliding member 22 to slide. In this embodiment, a handle 25 is also provided on the side of the pressing body 21. By holding the handle 25, the pressing body 21 can be removed, thereby attaching the pressing body 21 to the support assembly 10 or removing the pressing body 21 from the support assembly 10.

[0102] Thus, when the film pressing body 21 is attached to the carrier component 10, the sliding member 22 can be moved along the second direction by pushing the sliding push block 24. As a result, the sliding member 22 drives the film pressing part 231 of the film pressing member 23 to move along the second direction and press the main body part 310 of the film 300, pressing the main body part 310 of the film 300 onto the first surface 210 of the workpiece 200. This can effectively reduce defects such as film bubbles and misalignment.

[0103] In this embodiment, there are multiple pressing members 23 arranged at intervals, so that when the sliding member 22 slides, it can drive multiple pressing members 23 to perform film application on multiple workpieces 200.

[0104] Please continue reading Figure 3In some embodiments, the pressing body 21 has a through hole 211 in the first direction, making the pressing body 21 a hollow structure. The pressing body 21 is provided with two opposing sliding grooves 212, which extend in the second direction. The sliding member 22 is provided with a sliding part 221 at both ends, and the sliding part 221 is slidably connected in the corresponding sliding groove 212. The pressing part 231 is located in the hollow structure of the pressing body 21, so as to press the main body 310 to the first surface 210 under the action of the sliding member 22.

[0105] Thus, by setting the sliding groove 212 and making the sliding parts 221 at both ends of the sliding member 22 slidably connected in the corresponding sliding groove 212, the accuracy of the moving direction of the sliding member 22 can be guaranteed, and the sliding member 22 can be prevented from deviating from the second direction when moving, so that the main body 310 of the film 300 cannot be pressed and air bubbles will appear; by setting the film pressing body 21 as a hollow structure, it is mainly used to avoid the film pressing part 231 when pressing the film, and it is easy to process.

[0106] Please continue reading Figure 4 In some embodiments, the pressing member 23 further includes a pressing body 232 and an elastic portion 233; the sliding member 22 is provided with a slot 222 corresponding to the position of the pressing member 23, one end of the pressing body 232 is movably held in the slot 222 of the sliding member 22, and the other end of the pressing body 232 protrudes out of the through hole 211 of the sliding member 22 and the pressing body 21; the elastic portion 233 is located in the sliding member 22, and both ends of the elastic portion 233 abut against the bottom of the slot 222 of the pressing body 232 and the sliding member 22, respectively, so that the pressing body 232 can move in the first direction when the pressing body 21 is attached to the bearing assembly 10; the pressing portion 231 is rotatably connected to the bottom of the pressing body 232, wherein the pressing portion 231 can elastically abut against the main body portion 310 on the first surface 210 under the action of the elastic portion 233. In this embodiment, the elastic portion 233 is a spring.

[0107] Thus, by providing a slot 222 on the slider 22, one end of the pressing body 232 can be movably connected to the slider 22. By providing an elastic part 233 that abuts against the bottom of the slot 222 of the pressing body 232 and the slider 22 respectively, the pressing body 232 can be moved in the first direction when the pressing body 21 is attached to the bearing assembly 10, thereby elastically abutting against the main body part 310 on the first surface 210 and preventing overpressure on the main body part 310.

[0108] Please see Figure 5In some embodiments, the supporting assembly 10 further includes a supporting base 11, two support members 12, a supporting body 13, and a first elastic member 14. The supporting body 13 is disposed on the supporting base 11 and is used to support the workpiece 200. Two spaced-apart support blocks 17 protrude from the supporting base 11. The support members 12 are generally elongated, with two support members 12 spaced apart on the supporting base 11 and located between the two support blocks 17. Each support member 12 is located on one side of the supporting body 13 and has multiple upwardly protruding protrusions 121. Each protrusion 121 is used to support the end 320 of a membrane 300. In some embodiments, one or more support members 12 may be provided depending on the actual situation. The first elastic member 14 is disposed between the supporting base 11 and the support members 12. The two ends of the first elastic member 14 abut against the supporting base 11 and the support members 12, respectively, so that the support members 12 can move up and down in a first direction. In this embodiment, the first elastic member 14 is a spring.

[0109] Thus, by providing the support member 12 and the first elastic member 14, the support member 12 can elastically support the end 320 of the film 300 when the film pressing body 21 is attached to the carrier component 10, thereby protecting the end 320 of the film 300 and preventing wrinkles from appearing during film pressing. Furthermore, the support member 12 can move along the first direction and continuously support the end 320 until the end 320 folds towards the second surface 220 when the film folding body 31 is attached to the carrier component 10, thereby further preventing wrinkles from appearing at the end 320 of the protective film 300 during film folding.

[0110] In some embodiments, the support body 13 is further provided with two spaced limiting strips 18, which are located between the two support blocks 17. Each support member 12 is located between the corresponding limiting strip 18 and the support body 13. The limiting strips 18 are used to limit the position of the support member 12 and prevent the support member 12 from moving in the second direction.

[0111] In some embodiments, the support assembly 10 further includes a retaining block 15 and a second elastic member 16. The retaining block 15 is disposed between the support member 12 and the support base 11, and can slide out of the space between them along a third direction, which in this embodiment is the Y-axis direction. The second elastic member 16 is disposed between the retaining block 15 and the support block 17 of the support base 11. The two ends of the second elastic member 16 abut against the support block 17 of the support base 11 and the retaining block 15, respectively, so that the retaining block 15 has a tendency to move between the support member 12 and the support base 11. The retaining block 15 can move along a third direction between the support member 12 and the support base 11 under the action of the second elastic member 16 to restrict the descent of the support member 12. The retaining block 15 has an upwardly protruding pushing portion 151, which can move out of the space between the support member 12 and the support base 11 when the second elastic member 16 is compressed by the pushing portion 151, so as to allow the support member 12 to descend. In this embodiment, the second elastic member 16 is a spring.

[0112] Thus, by providing the abutment block 15 and the second elastic member 16, the descent of the support member 12 can be restricted when the film pressing body 21 is attached to the carrier assembly 10, so that the support member 12 supports the end 320 of the film 300, and the support member 12 is lowered when the film folding body 31 is attached to the carrier assembly 10, thereby enabling the film folding member 32 to move in the first direction and abut the end 320 to fold the end 320 toward the second surface 220.

[0113] Please see Figure 6 In some embodiments, the folding assembly 30 includes a first abutment portion 331 and a second abutment portion 332 disposed offset from the first abutment portion 331. Both the first abutment portion 331 and the second abutment portion 332 may be block-shaped, but are not limited thereto. The first abutment portion 331 is adapted to push against the pushing portion 151 of the abutment block 15 when the folding body 31 is attached to the support assembly 10, causing the abutment block 15 to move out between the support member 12 and the support base 11. The second abutment portion 332 is adapted to abut against the support member 12 when the folding body 31 is attached to the support assembly 10, causing it to descend so that the end 320 can be folded. In this embodiment, the first abutment portion 331 and the second abutment portion 332 are two sets, each set corresponding to the support member 12 and the abutment block 15 on one side of the support body 13.

[0114] Thus, by providing the first contact portion 331, the push portion 151 of the support block 15 can be pushed against the support block 15 while the folded film body 31 is attached to the support assembly 10, so that the support block 15 moves out between the support member 12 and the support base 11, thereby allowing the support member 12 to be pressed down; by providing the second contact portion 332, the second contact portion 332 can abut against the support member 12, causing the support member 12 to descend, thereby allowing the folded film member 32 to move in the first direction and abut against the end portion 320, so that the end portion 320 is folded towards the second surface 220.

[0115] In some embodiments, the folding assembly 30 further includes two abutment blocks 33, which are protrudingly disposed below the folding body 31. Each abutment block 33 includes a first abutment portion 331 and a second abutment portion 332; wherein, the pushing portion 151 of the abutment block 15 has a pushing slope 1511. Figure 5 As shown), after the first contact portion 331 contacts the pushing ramp 1511, the holding block 15 is pushed to move along a third direction, wherein the pushing ramp 1511 is arranged inclined along the third direction. In other embodiments, the first contact portion 331 has the pushing ramp 1511, or both the pushing portion 151 and the first contact portion 331 have the pushing ramp 1511.

[0116] Thus, by providing a pushing ramp 1511 on the pushing part 151, the first abutting part 331 can push the holding block 15 to move at a relatively uniform speed.

[0117] In some embodiments, the folding assembly 30 further includes a film-pushing member 34 and a third elastic member 35. The film-pushing member 34 is slidably connected to the folding body 31 along a second direction. The film-pushing member 34 is elongated and includes an operating end 341 and an output end 342 disposed opposite to each other, with the output end 342 abutting against the folding member 32. The third elastic member 35 is disposed between the folding body 31 and the film-pushing member 34, and is used to provide a restoring force to the film-pushing member 34 after it has been operated. In this embodiment, the third elastic member 35 is a spring, and there are two of them.

[0118] Thus, by setting a pushing member 34 that abuts against the folding member 32, it is possible to conveniently and ensure that the folding member 32 moves along the second direction. The moving direction of the folding member 32 is highly accurate. By setting a third elastic member 35, it is possible to ensure that the pushing member 34 returns to its initial position after folding.

[0119] Please see also Figure 7In some embodiments, the folding assembly 30 further includes a fourth elastic element 36. Multiple folding elements 32 are spaced apart along a third direction. The multiple folding elements 32 are rotatably connected to the folding body 31 via a pivot 37. Multiple fourth elastic elements 36 are disposed between corresponding folding elements 32 and the folding body 31. The fourth elastic element 36 provides an elastic force to reset the folding element 32 after it rotates due to contact with the workpiece 200. Optionally, the fourth elastic element 36 is a spring, torsion spring, etc.

[0120] Thus, by providing the fourth elastic member 36, the folding member 32 can move relative to the folding body 31 in the second direction when pushed by the pushing member 34, and one end of the folding member 32, the folded end 320, can be elastically pressed against the second surface 220, and the folding member 32 can be reset after folding.

[0121] In some cases, when there is a deviation in the distance between the free end of the film folding member 32 and the workpiece 200, or when it is necessary to further tighten the film 300, the film folding member 32 will come into contact with the workpiece 200 during the movement. However, due to the configuration of the fourth elastic member 36, the film folding member 32 has a certain rotational ability, which avoids the workpiece 200 from blocking the film folding member 32, so that the film application process can be completed smoothly.

[0122] In some embodiments, after the folding assembly 30 is attached to the carrier assembly 10, the height of the portion of the folding member 32 used for pressing the end 320 is consistent with the height of the second surface 220, so that during the movement of the folding member 32 in the second direction, one end of the folding member 32 presses the end 320 against the second surface 220.

[0123] It is understood that in some embodiments, after the folding assembly 30 is attached to the carrier assembly 10, the height of the portion of the folding member 32 used for pressing the end 320 is higher than the second surface 220, and the height of the other portion used for abutting the workpiece 200 is lower than the second surface 220. In this way, during the movement of the folding member 32 in the second direction, the folding member 32, under the action of the fourth elastic member 36, causes one end of the folding member 32 to elastically press the end 320 against the second surface 220.

[0124] In some embodiments, the folding body 31 further includes a folding plate 311, a connecting block 312, and a movable block 313. The connecting block 312 is connected to the lower surface of the folding plate 311. In this embodiment, the connecting block 312 and the folding plate 311 are independent structures. It can be understood that in other embodiments, the connecting block 312 and the folding plate 311 are an integral structure. The film pushing member 34 is slidably connected to the connecting block 312 along the second direction, and the third elastic member 35 is disposed between the connecting block 312 and the film pushing member 34. The movable block 313 is movably disposed on the connecting block 312 along the second direction and abuts against the output end 342 of the film pushing member 34. The folding member 32 is rotatably connected to the movable block 313.

[0125] In some embodiments, the folding member 32 is generally block-shaped, with its central portion hinged to the movable block 313 via a pivot 37. A free end 321 located on either side of the central portion of the folding member 32 is used to press the end portion 320 against the second surface 220, and a connecting end 322 is used to connect to the movable block 313 via a linear elastic element. The fourth elastic element 36 includes a linear elastic element. In this embodiment, the fourth elastic element 36 is a spring; however, it is understood that in other embodiments, the fourth elastic element 36 is rubber, but is not limited thereto.

[0126] In other modified embodiments, the fourth elastic element 36 is selected as a torsion spring, which is connected between the folding element 32 and the movable block 313, so that the folding element 32 also has a certain degree of mobility and resetting capability.

[0127] In some embodiments, please also refer to Figures 8 to 12 The phrase "the state in which the folded membrane body 31 is attached to the support assembly 10" includes a first state in which the folded membrane body 31 moves toward the support assembly 10 along a first direction, and a second state in which the folded membrane body 31 completes attachment to the support assembly 10; wherein Figures 8 to 10 In the first state, the end 320 is folded towards the second surface 220 by the folding member 32; Figure 11 and Figure 12 In the second state, the folding member 32 moves along the second direction to press the end 320 against the second surface 220.

[0128] Thus, by coordinating the first and second states, the end 320 of the membrane 300 can be pressed against the second surface 220 of the workpiece 200.

[0129] In some embodiments, see Figure 3 , Figure 5 and Figure 6 The film application device 100 also includes a positioning mechanism 40 and a connecting rod 50.

[0130] The positioning mechanism 40 includes a cooperating pin hole 41 and a pin 42. One of the pin hole 41 and the pin 42 is located on the support block 17 of the bearing assembly 10, and the other is located on the pressing assembly 20 and the folding assembly 30. In this embodiment, the pin hole 41 is located on the pressing assembly 20 and the folding assembly 30, and the pin 42 is located on the bearing assembly 10.

[0131] Thus, by providing matching pin holes 41 and pin posts 42, the pressing body 21 of the pressing assembly 20 can be attached to the support assembly 10, and the folding body 31 of the folding assembly 30 can be attached to the support assembly 10.

[0132] One end of the connecting rod 50 is hinged to the support block 17 of the bearing assembly 10, and the other end of the connecting rod 50 is hinged to the cam 60. The connecting rod 50 can rotate and engage with the first groove 213 provided on the edge of the pressing body 21 and the second groove 314 provided on the edge of the folding body 31, and the cam 60 can rotate to press the folding body 31 and the pressing body 21 tightly onto the bearing assembly 10.

[0133] Thus, by setting the connecting rod 50, cam 60, first groove 213 and second groove 314, the film folding body 31 and the film pressing body 21 can be locked to the bearing assembly 10, thereby performing film application and film folding operations.

[0134] This application is attached. Figure 2-12 The working process of the film application device 100 in the illustrative embodiment is as follows:

[0135] First, multiple workpieces 200 and a membrane 300 disposed on the first surface 210 of the workpieces 200 are respectively placed on the carrier body 13;

[0136] Then, the pressing body 21 is placed on the support body 13, wherein the pin 42 on the support body 13 is inserted into the pin hole 41 of the pressing body 21, the connecting rod 50 is rotated so that the connecting rod 50 is engaged in the first groove 213 provided on the edge of the pressing body 21, the cam 60 is rotated so that the cam 60 presses the pressing body 21 against the support assembly 10, the sliding push block 24 is held and the sliding member 22 is pushed to slide along the second direction, thereby driving the pressing part 231 of the multiple pressing parts 23 to move along the second direction so as to elastically press the main body 310 of the multiple films 300 onto the first surface 210 of the multiple workpieces 200 respectively;

[0137] Finally, disassemble and remove the film pressing body 21, and attach the folding film body 31 to the carrier body 13. Please refer to [link / reference needed]. Figures 8 to 10 ,exist Figure 8 In the middle, the folding body 31 moves towards the support body 13 along the first direction. At this time, part of the pin 42 on the support body 13 is inserted into the pin hole 41 of the folding body 31. Then, the folding body 31 and the folding component 32 move downward along the first direction. Figure 9 In the middle state, the first contact part 331 pushes against the push part 151 of the support block 15, causing the support block 15 to move out between the support member 12 and the bearing base 11. The second contact part 332 abuts against the support member 12, causing the support member 12 to descend. One end of the end 320 abuts against the upper surface of the support member 12, and the included angle between the end 320 and the main body 310 is an obtuse angle. Then, the folding body 31 and the folding member 32 continue to move downward along the first direction. Figure 10 In the current state, the end 320 of the film folding member 32 that contacts the film 300 is folded towards the second surface 220. The end 320 and the main body 310 are perpendicularly arranged. Then, the connecting rod 50 is rotated so that the connecting rod 50 is engaged in the second groove 314 provided on the edge of the film folding body 31. The cam 60 is rotated so that the cam 60 presses the film folding body 31 against the supporting body 13. After that, please refer to... Figure 11 and Figure 12 ,exist Figure 11 In the middle, the film pusher 34 pushes the folding member 32 to move relative to the folding body 31 in the second direction, so that the pushing end 320 of the folding member 32 is folded. At this time, the included angle between the end 320 and the main body 310 is an acute angle. Then the film pusher 34 continues to push the folding member 32 to move relative to the folding body 31 in the second direction until the end 320 is folded. Figure 12 In this state, the film pusher 34 pushes the folding film member 32 to press the folded end 320 against the second surface 220, thereby completing the film application 300, and then disassembling and removing the folding film body 31.
