Description

Technical Field

[0001] This application relates to the field of film application technology, specifically to a film application device. Background Technology

[0002] During the shipping or processing of electronic products, the product surface is easily damaged by scratches, contamination, or oxidation. Therefore, a protective film needs to be applied to the surface to ensure that the product maintains its appearance and function during transportation and processing. Currently, the industry typically uses manual application of the film. However, this method has many drawbacks: First, manual operation is complex and inconsistent, making it easy to scratch the product surface due to improper operation; second, the labor intensity for employees is high, and prolonged work can easily lead to fatigue, further increasing the risk of operational errors; in addition, manual film application is inefficient, making it difficult to meet the needs of large-scale production, and the labor cost is high. Utility Model Content

[0003] In view of the above, it is necessary to propose a film-applying device that can automatically apply film to workpieces, with a high degree of automation, low labor intensity, good film application consistency, and high work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0024] Please see Figure 1 , Figure 2 and Figure 3 This application provides a film-applying device 100 for applying a film 300 to a workpiece 200. The workpiece 200 can be an electronic product or its casing, such as a mobile phone, computer, or main unit. Of course, the workpiece 200 can also be any other product requiring external surface protection. In this embodiment, a main unit casing is used as an example. The workpiece 200 is generally square with an internal cavity and curved corners. This is not intended to limit the scope of this application. The film 300 can be applied to the upper surface or side surface of the workpiece 200. When applied to the side surface, it can be applied to one, two, or more sides of the workpiece 200, depending on actual needs, and is not limited here.

[0025] The film application device 100 includes a transmission mechanism 10, a film supply mechanism 20, a film application mechanism 30, and a feeding mechanism 40.

[0026] Specifically, the transmission mechanism 10 includes a transmission component 11 and multiple fixtures 12. The transmission component 11 has a ring-shaped structure, and the multiple fixtures 12 are spaced apart on the transmission component 11. The transmission component 11 is used to cyclically transmit the multiple fixtures 12, and the fixtures 12 are used to support and position the workpiece 200. The transmission component 11 may include four magnetic tracks that are perpendicular to each other and connected end to end. The fixtures 12 may include magnetic bases, and the fixtures 12 are slidably disposed on the transmission component 11. The transmission component 11 drives the fixtures 12 to move sequentially along the four magnetic tracks by magnetic force. It can be understood that the transmission component 11 can also be other structures, such as a ring-shaped drive track, with the fixtures 12 slidably connected to the ring track, and the ring track driving the fixtures 12 to move. Of course, the transmission component 11 can also be other transmission devices, as long as they can drive multiple fixtures 12 to perform ring-shaped cyclic movement, which is not limited here. There can be four, six, twelve, etc., of fixtures 12, which are spaced apart and do not interfere with each other. The specific number depends on actual needs and is not limited here. The transmission component 11 drives multiple fixtures 12 to move in a clockwise or counterclockwise direction. In this embodiment, the example of the transmission component 11 driving multiple fixtures 12 to move in a counterclockwise direction will be used for explanation.

[0027] The film supply mechanism 20 is disposed adjacent to the transmission assembly 11, and the film supply mechanism 20 is used to supply film components 300. The film supply mechanism 20 accommodates multiple film components 300 for film application.

[0028] The film application mechanism 30 includes a drive assembly 31, a film application gripper 32, and a rolling assembly 33. The drive assembly 31 is disposed adjacent to the transmission assembly 11 and the film supply mechanism 20. The film application gripper 32 is connected to the drive assembly 31. The drive assembly 31 is used to drive the film application gripper 32 to take out the film piece 300 from the film supply mechanism 20 and apply the film piece 300 to the workpiece 200. The rolling assembly 33 is connected to the drive assembly 31. The drive assembly 31 is also used to drive the rolling assembly 33 to roll the film piece 300 applied to the workpiece 200. The film-applying gripper 32 can be an adsorption type gripper. The size of the film-applying gripper 32 is adapted to the size of the film component 300. For example, if the film component 300 is rectangular, the side of the film-applying gripper 32 used to adsorb the film component 300 is rectangular and has multiple vacuum holes. The film-applying gripper 32 is connected to an external air extraction device (not shown in the figure). The external air extraction device extracts air to create negative pressure on the side of the film-applying gripper 32 used to adsorb the film component 300, thereby adsorbing the film component 300. It can be understood that when the workpiece 200 has a curved surface structure, the rolling assembly 33 can roll the position corresponding to the curved surface structure to adhere to the workpiece 200. Of course, the rolling assembly 33 can also be used to roll the film component 300 adhered to the surface of the workpiece 200, so that the film component 300 is tightly adhered to the surface of the workpiece 200, reducing the generation of air bubbles and wrinkles, thereby improving the quality and reliability of film application.

[0029] The unloading mechanism 40 is located close to the transmission mechanism 10. The unloading mechanism 40 is used to remove the workpiece 200 with the film 300 attached from the fixture 12. In this way, the workpiece 200 with the film attached can be removed from the fixture 12, making it easier for the fixture 12 to place the workpiece 200 to be attached.

[0030] The film-applying device 100 provided in this embodiment drives multiple fixtures 12 to circulate via a transmission component 11. The fixtures 12 are used to carry and position the workpiece 200. When the workpiece 200 moves to a position corresponding to the film-applying mechanism 30, the drive component 31 controls the film-applying gripper 32 to remove the film 300 from the film supply mechanism 20 and precisely apply the film 300 to the surface of the workpiece 200. Subsequently, the rolling component 33 rolls the film 300 to ensure a tight fit between the film 300 and the workpiece 200. The film-applying device 100 significantly improves film-applying efficiency, effect, and consistency. When the workpiece 200 moves to a position corresponding to the unloading mechanism 40, the unloading mechanism 40 automatically removes the film-applied workpiece 200 from the fixtures 12, achieving a high degree of automation. In addition, the transmission component 11 adopts a ring structure design, which can drive multiple fixtures 12 to reciprocate. During the film application process, there is no need to disassemble the fixtures 12. Only the workpiece 200 to be applied needs to be placed on the fixtures 12, which greatly reduces the labor intensity of the operators.

[0031] In some embodiments, see Figure 1 and Figure 3The driving assembly 31 includes a film-applying driving component 311 and a flipping driving component 312. The film-applying driving component 311 is disposed adjacent to the transmission assembly 11 and the film supply mechanism 20. The flipping driving component 312 is connected to the film-applying driving component 311. The film-applying gripper 32 and the rolling assembly 33 are both connected to the flipping driving component 312. The film-applying driving component 311 is used to drive the flipping driving component 312, the film-applying gripper 32 and the rolling assembly 33 to move. The flipping driving component 312 is used to drive the film-applying gripper 32 and the rolling assembly 33 to flip so that the position of the film-applying gripper 32 corresponds to the position of the film piece 300 in the film supply mechanism 20 or to the position of the workpiece 200 to be film-applied, and so that the position of the rolling assembly 33 corresponds to the position of the film piece 300 that is applied to the workpiece 200.

[0032] The film-applying drive 311 can be a drive mechanism such as a robotic arm, and the flipping drive 312 can be a flipping cylinder, etc. In this embodiment, the film-applying drive 311 can drive the flipping drive 312 to move freely in three-dimensional space, thereby driving the film-applying gripper 32 and the rolling assembly 33 to move freely in three-dimensional space. It can be understood that in order to improve the positional consistency of unused film pieces 300, the film supply mechanism 20 often uses a method of stacking multiple film pieces 300 in the vertical direction to store film pieces 300. When grasping unused film pieces 300, the flipping drive 312 drives the film-applying gripper 32 to rotate 90° so that the side of the film-applying gripper 32 used to adsorb the film piece 300 is on the horizontal plane. Then, the film-applying drive 311 drives the flipping drive 312 to drive the film-applying gripper 32 to take out the unused film piece 300 from the film supply mechanism 20. When applying film to the side wall of workpiece 200, the flipping drive 312 drives the film-applying gripper 32 to rotate 90°, so that the film-applying gripper 32 rotates the film 300 to a vertical position, corresponding to the side of workpiece 200. Then, the film-applying drive 311 drives the flipping drive 312, which in turn moves the film-applying gripper 32 and the film 300 toward the side of workpiece 200, so as to adhere the film 300 to workpiece 200. It can be understood that if film application is required on the horizontal surface of workpiece 200, the flipping drive 312 can keep the film-applying gripper 32 and the film 300 in a horizontal state during film application. If the film 300 provided by the film supply mechanism 20 is vertically positioned, the side of the film-applying gripper 32 used to adsorb the film 300 can be in a vertical position when picking up the film.

[0033] In some embodiments, see Figure 1 and Figure 3The rolling assembly 33 includes a support plate 331, a sliding seat 332, a roller frame 333, a roller 334, and an elastic element 335. The support plate 331 is connected to the flipping drive 312. The sliding seat 332 is connected to the side of the support plate 331 away from the flipping drive 312. The sliding seat 332 has a sliding groove 3321. The roller frame 333 is slidably disposed in the sliding groove 3321 and extends in a direction away from the support plate 331. The roller 334 is rotatably connected to the roller frame 333. The elastic element 335 is disposed in the sliding groove 3321, and the two ends of the elastic element 335 abut against the groove wall of the roller frame 333 and the sliding groove 3321, respectively.

[0034] The support plate 331 can be a plate-like structure. In this embodiment, the plane of the support plate 331 is perpendicular to the plane of the side of the film-adhesive gripper 32 used to adsorb the film 300. The sliding seat 332 is roughly U-shaped, with a sliding groove 3321 inside. The roller frame 333 is roughly strip-shaped, the roller 334 is roughly cylindrical, and the elastic element 335 can be a spring, etc. The connection between the roller frame 333 and the sliding seat 332 can be that a guide rod is provided in the sliding groove 3321, and the roller 334 is sleeved on the guide rod, thereby making the roller frame 333 and the sliding seat 332 slidably connected. Of course, the roller frame 333 and the sliding seat 332 can also be slidably connected by a slide rail, dovetail groove structure, etc. In order to improve the stability of the elastic element 335 pushing the roller frame 333, multiple elastic elements 335 can be provided, such as two or three, etc., and multiple elastic elements 335 together push the roller frame 333. In this embodiment, two sets of sliding seat 332, roller frame 333, roller 334, and elastic element 335 are provided and arranged symmetrically. When rolling the film 300, the flipping drive 312 first flips the support plate 331 so that the support plate 331 is opposite to the film 300 attached to the workpiece 200. Then, the film application drive 311 drives the support plate 331 to move toward the film 300 through the flipping drive 312. At this time, the roller 334 abuts against the film 300 so that the roller 334 rolls the film 300, improving the flatness and quality of the film application. In this embodiment, the roller 334 is positioned opposite the arc surface of the workpiece 200. When the film application drive 311 drives the rolling assembly 33 toward the film 300 and the workpiece 200 via the flipping drive 312, the roller 334 abuts against the position opposite the arc surface. The roller 334 then rolls the film 300 opposite the arc surface toward the workpiece 200, so that the film 300 adheres to the arc surface position of the workpiece 200. During the rolling process, the roller 334 moves along the arc surface, thereby driving the roller frame 333 to slide along the sliding seat 332. The roller frame 333 compresses the elastic member 335, and the elastic member 335 provides elastic force, which is then transmitted to the roller 334 through the roller frame 333, increasing the force of the roller 334 rolling the film 300 and improving the film application effect.

[0035] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The film supply mechanism 20 includes a locking component 21, a film chamber 22, and a lifting component 23. The locking component 21 is located adjacent to the transmission component 11. The film chamber 22 is detachably connected to the locking component 21 and is used to carry multiple stacked film components 300. The lifting component 23 includes a lifting drive component 231 and a lifting component 232. The lifting drive component 231 is located close to the locking component 21. The lifting component 232 is connected to the lifting drive component 231 and can be inserted into the film chamber 22. One end of the lifting component 232 inserted into the film chamber 22 abuts against the lowest layer of film component 300. The lifting drive component 231 is used to drive the lifting component 232 to move and push the film component 300 upward.

[0036] By setting the locking component 21, the film chamber 22 can be fixed in a designated position, ensuring the stability of the film component 300 during supply and preventing the film component 300 from shifting or becoming misaligned due to movement of the film chamber 22. The film chamber 22 is detachably connected to the locking component 21, allowing for quick replacement of an empty film chamber 22 with one full of film components 300, reducing standby time and improving film application efficiency. Furthermore, the detachable connection between the film chamber 22 and the locking component 21 facilitates quick replacement of different types or specifications of film components 300 to meet the film application needs of different workpieces 200. The lifting drive component 231 can be a lifting cylinder, etc., and the lifting component 232 can be a plate-shaped or strip-shaped structure. When installing the film compartment 22 into the locking assembly 21, the lifting member 232 is inserted into the film compartment 22 and abuts against the bottommost film 300. After the topmost film 300 is removed, the lifting drive member 231 drives the lifting member 232 to move upward by the thickness of one film 300, so that the next topmost film 300 moves to the film removal position, making it easier for the film applicator gripper 32 to remove the film.

[0037] In some embodiments, see Figure 1 and Figure 2 The membrane component 300 has a plurality of through holes 301 spaced apart. The membrane component 300 may have two, three, four or more through holes 301. In this embodiment, the membrane component 300 has two through holes 301 spaced apart.

[0038] The membrane chamber 22 includes a base plate 221, multiple spacers 222, and multiple guide rods 223. The base plate 221 is detachably connected to the locking assembly 21. The multiple spacers 222 are spaced apart on the side of the base plate 221 away from the locking assembly 21. Each guide rod 223 is respectively located on the side of each spacer 222 away from the base plate 221, and the guide rod 223 extends in a direction perpendicular to the plane of the base plate 221. The multiple guide rods 223 are correspondingly arranged with multiple through holes 301. A limiting protrusion 2231 is provided at the end of the guide rod 223 away from the spacer 222. The diameter of the guide rod 223 is smaller than the diameter of the through hole 301, and the diameter of the limiting protrusion 2231 is larger than the diameter of the through hole 301. The guide rod 223 is used to insert into the corresponding through hole 301 to support the membrane component 300, and the limiting protrusion 2231 is used to stop the membrane component 300.

[0039] The base plate 221 has a plate-like structure, and the spacer block 222 has a block-like structure. The number of spacer blocks 222 can be two, three, or four, etc. In this embodiment, two spacer blocks 222 are provided. The connecting rod 223 has a rod-like structure, and the number of connecting rods 223 can be two, three, or four, etc. In this embodiment, two connecting rods 223 are provided, and the two connecting rods 223 are respectively connected to the two spacer blocks 222. To facilitate the installation and removal of the membrane component 300 from the connecting rod 223, both the upper and lower ends of the limiting protrusion 2231 are provided with inclined or arc-shaped surfaces. When installing the membrane component 300 into the membrane chamber 22, the connecting rod 223 simply passes through the through hole 301 of the membrane component 300, making installation convenient. It is understood that the membrane element 300 itself is elastic, allowing it to pass through the limiting protrusion 2231. After multiple membrane elements 300 are stacked and installed on the connecting rod 223, the uppermost membrane element 300 abuts against the limiting protrusion 2231. Without applying external force, the limiting protrusion 2231 can limit the membrane element 300. After multiple membrane elements 300 are stacked and installed on the connecting rod 223, the lowermost membrane element 300 abuts against the spacer block 222. The spacer block 222 stops the membrane element 300, creating a gap between the lowermost membrane element 300 and the base plate 221. During membrane supply, the lifting member 232 inserts into the gap between the membrane element 300 and the base plate 221, thereby abutting against the lowest layer of membrane element 300. When removing the membrane, the film-applying gripper 32 simply picks up the uppermost membrane element 300 and removes it from the top of the connecting rod 223.

[0040] In some embodiments, see Figure 1 and Figure 2The locking assembly 21 includes a support frame 211, a positioning pin 212, a locking drive 213, and a locking member 214. The support frame 211 is located near the transmission assembly 11 and is used to support the base plate 221. The positioning pin 212 is located on one side of the support frame 211 that supports the base plate 221. The locking drive 213 is connected to the side of the support frame 211 away from the positioning pin 212. The locking member 214 is connected to the locking drive 213 and passes through the support frame 211. A locking protrusion 2141 is provided at the end of the locking member 214 away from the locking drive 213. The locking drive 213 is used to drive the locking member 214 to rotate and extend. The base plate 221 has a positioning hole 2211 and a locking hole 2212. The positioning hole 2211 is correspondingly set with the positioning pin 212, and the locking hole 2212 is correspondingly set with the locking member 214. When the base plate 221 is placed on the support frame 211, the positioning pin 212 is inserted into the positioning hole 2211 to position the base plate 221, and the locking member 214 passes through the locking hole 2212. The locking drive member 213 is used to drive the locking member 214 to rotate and move toward the locking drive member 213 so that the locking protrusion 2141 presses the base plate 221.

[0041] The support frame 211 is roughly U-shaped. The number of positioning pins 212 can be multiple, such as two, three, or four. In this embodiment, two positioning pins 212 are provided. The locking drive component 213 can be a rotary telescopic cylinder. The locking component 214 is roughly T-shaped, with a locking protrusion 2141 protruding horizontally from the body of the locking component 214. The number of positioning holes 2211 can be multiple, such as two, three, or four. In this embodiment, two positioning holes 2211 are provided, corresponding one-to-one with the positions of the two positioning pins 212. The locking holes 2212 are strip-shaped holes, corresponding to the positions of the locking components 214.

[0042] The locking assembly 21 locks the membrane chamber 22 in roughly the following manner: First, the locking drive 213 drives the locking member 214 away from the locking drive 213 and rotates the locking member 214 so that the locking protrusion 2141 is aligned with the extending direction of the locking hole 2212. Then, the bottom plate 221 of the membrane chamber 22 is placed on the support frame 211, and the positioning pin 212 is inserted into the corresponding positioning hole 2211 to position the bottom plate 221, so that the locking member 214 passes through the locking hole 2212. Finally, the locking drive 213 drives the locking member 214 to rotate 90° and moves the locking member 214 toward the locking drive 213, thereby pressing the locking protrusion 2141 against the bottom plate 221, completing the locking of the membrane chamber 22.

[0043] In some embodiments, see Figure 1 and Figure 2The film supply mechanism 20 also includes a material sensor 24, which is positioned near the locking assembly 21 and corresponds to the top of the film chamber 22. The material sensor 24 is used to detect the uppermost film element 300 in the film chamber 22. The material sensor 24 can be an infrared sensor or the like. Since it corresponds to the uppermost film element 300, it can detect the uppermost film element 300 in the film chamber 22 in real time. When the film element 300 in the film chamber 22 is no longer in use, it can promptly send a signal to remind the user to replace the film chamber 22.

[0044] In some embodiments, see Figure 1 , Figure 2 and Figure 3 A release film 400 is attached to the membrane component 300. The release film 400 can be release paper or the like. The release film 400 protects the adhesive surface of the membrane component 300 and prevents the membrane components 300 from sticking together. In this embodiment, the length of the release film 400 is greater than the length of the membrane component 300, and both ends of the release film 400 extend beyond the membrane component 300. It is understood that the release film 400 is also provided with through holes 301 corresponding to the connecting rod 223 to facilitate the installation of the membrane component 300 and the release film 400 on the connecting rod 223. In another embodiment, the through holes 301 can be provided only at the position where the release film 400 extends beyond the membrane component 300, which can reduce the probability of deformation of the membrane component 300.

[0045] The film supply mechanism 20 also includes a film-tearing assembly 25 and a waste container 26. The film-tearing assembly 25 includes a film-tearing drive 251 disposed near the locking assembly 21 and a film-tearing gripper 252 connected to the film-tearing drive 251. The waste container 26 is disposed below the film-tearing gripper 252. The film-tearing drive 251 drives the film-tearing gripper 252 to clamp the release film 400, so as to cooperate with the drive assembly 31 and the film-applying gripper 32 to tear off the release film 400 from the film component 300. The waste container 26 is used to collect the release film 400. The film-tearing drive 251 can be a cylinder or the like. The film-tearing gripper can include two fingers. The film-tearing drive 251 drives the two fingers of the film-tearing gripper to move closer or further apart to clamp or release the film component 300. After the film-applying gripper 32 removes the film component 300 with the release film 400 attached from the hopper, the drive assembly 31 drives the film-applying gripper 32 to move to the position of the film-tearing assembly 25, aligning the release film 400 with the film-tearing gripper 252. The film-tearing drive assembly 251 drives the film-tearing gripper 252 to clamp the release film 400. Then, the drive assembly 31 drives the film-applying gripper 32 and the film component 300 away from the film-tearing drive assembly 251, thereby separating the release film 400 from the film component 300. The film-tearing drive assembly 251 then drives the film-tearing gripper 252 to release the release film 400, which falls into the waste box 26.

[0046] In some embodiments, see Figure 1The fixture 12 includes a carrier 121 and a plurality of positioning blocks 122. The carrier 121 is disposed on the transmission assembly 11 and is used to carry the workpiece 200. The plurality of positioning blocks 122 are disposed on the side of the carrier 121 used to carry the workpiece 200, and the plurality of positioning blocks 122 are used to abut against the side wall of the workpiece 200 to position the workpiece 200. The number of positioning blocks 122 can be four, eight, etc. In this embodiment, the plurality of positioning blocks 122 are used to abut against the inner side wall of the workpiece 200 to position the workpiece 200 on the carrier 121. In other embodiments, the plurality of positioning blocks 122 can also abut against the outer side wall of the workpiece 200 to position the workpiece 200 on the carrier 121. By accurately positioning the workpiece 200 with the positioning blocks 122, it is ensured that the film 300 can be accurately attached to the designated area of ​​the workpiece 200, avoiding poor film attachment caused by workpiece 200 misalignment. Multiple positioning blocks 122 can be detachably connected to the carrier 121 to facilitate adjustment of the position of the positioning blocks 122 on the carrier 121. This allows for adjustment or replacement according to the needs of workpieces 200 of different sizes, enhancing the versatility of the equipment.

[0047] In some embodiments, see Figure 1 and Figure 4 The unloading mechanism 40 includes a horizontal drive component 41, a vertical drive component 42, and an unloading gripper 43. The horizontal drive component 41 is mounted above the transmission assembly 11, the vertical drive component 42 is connected to the horizontal drive component 41, and the unloading gripper 43 is connected to the vertical drive component 42. The horizontal drive component 41 drives the vertical drive component 42 and the unloading gripper 43 to move horizontally, and the vertical drive component 42 drives the unloading gripper 43 to move vertically. The unloading gripper 43 is used to grasp or release the workpiece 200. The horizontal drive component 41 can be a linear module, the vertical drive component 42 can be a telescopic cylinder, and the unloading gripper 43 can be a suction cup gripper. The cooperative design of the horizontal drive component 41 and the vertical drive component 42 enables the unloading gripper 43 to move in both horizontal and vertical directions, accurately grasping the workpiece 200 with the film component 300 attached and removing it from the fixture 12, thus improving the degree of automation.

[0048] The working process of the film application device 100 provided in this embodiment is roughly as follows:

[0049] First, the workpiece 200 is placed on the carrier 121 of the fixture 12, and the workpiece 200 is precisely positioned by the positioning block 122 to ensure that the workpiece 200 remains stable during the film application process. The transmission component 11 begins to cyclically transmit the fixture 12, so that the fixture 12 moves the workpiece 200 toward the film application mechanism 30.

[0050] Then, the drive assembly 31 in the film application mechanism 30 drives the film application gripper 32 to grab the film piece 300 from the film supply assembly. Specifically, the flipping drive assembly 312 drives the film application gripper 32 so that the side of the film application gripper 32 used to adsorb the film piece 300 is on a horizontal plane. Then, the film application drive assembly 311 drives the flipping drive assembly 312, thereby moving the film application gripper 32 toward the film chamber 22. After the film application gripper 32 grabs the uppermost film piece 300 in the film chamber 22, it removes the film piece 300 from the string rod 223 of the film chamber 22 and moves the film piece 300 and the release film 400 connected to the film piece 300 toward the film tearing assembly 25, so that the release film 400 corresponds to the film tearing gripper 252. The film-tearing drive unit 251 drives the film-tearing gripper 252 to clamp the release film 400. Then, the drive assembly 31 drives the film-applying gripper 32 and the film 300 away from the film-tearing drive unit 251, thereby separating the release film 400 from the film 300. The film-tearing drive unit 251 then drives the film-tearing gripper 252 to release the release film 400, and the release film 400 falls into the waste box 26. Then, the lifting drive unit 231 drives the lifting component 232 to lift the remaining film 300 on the string rod 223 upward.

[0051] When the fixture 12 moves the workpiece 200 to a position corresponding to the film-applying mechanism 30, the flipping drive 312 drives the film-applying gripper 32 to rotate 90°, so that the film-applying gripper 32 rotates the film 300 to a vertical plane, corresponding to the side of the workpiece 200. Then, the film-applying drive 311 drives the flipping drive 312, which in turn moves the film-applying gripper 32 and the film 300 toward the side of the workpiece 200, so that the film 300 is applied to the workpiece 200. Then, the film-applying drive 311 drives the flipping drive 312 away from the workpiece 200, and the flipping drive 312 drives the rolling assembly 33 to flip, so that the rolling assembly 33 corresponds to the film 300. The film-applying drive 311 then drives the rolling assembly 33 toward the film 300 through the flipping drive 312, thereby pressing the film 300 tightly onto the workpiece 200.

[0052] If multiple film components 300 need to be attached to the workpiece 200, multiple film supply mechanisms 20 and film application mechanisms 30 can be provided to apply film to multiple positions of the workpiece 200.

[0053] After the film is applied, the transfer assembly 11 transfers the fixture 12 and the workpiece 200 to the unloading mechanism 40. The horizontal drive 41 and the vertical drive 42 of the unloading mechanism 40 work together to drive the unloading gripper 43 to move above the workpiece 200 after the film is applied. The unloading gripper 43 grabs the workpiece 200 with the film 300 applied, removes it from the fixture 12, and sends it to the subsequent process or the finished product area.

[0054] Finally, the transfer component 11 moves the fixture 12, after removing the workpiece 200, to the position where the workpiece 200 is installed. The operator can then continue to install the workpiece 200 onto the fixture 12 and repeat the above actions.
