[0034] The first rolling assembly 7 includes a first rolling element 71 and a first driving element 72 that drives the first rolling element 71 to move up and down. When applying the film, the first rolling element 71 is driven by the first driving element 72 to press the film against the workpiece. After the film is applied, the first rolling element 71 is driven away from the workpiece by the first driving element 72. Specifically, the first driving element 72 is suspended above the workpiece, and a first support is provided at the lower end of the first driving element 72. The first rolling element 71 is rotatably mounted on the first support, and the first driving element 72 drives the first rolling element 71 to move up and down above the workpiece.

Preferably, the first driving member 72 is a cylinder, and the piston rod of the cylinder is provided with the first support member. The first support member is preferably a bearing support. The first support member is provided with a first rolling member 71 rotatably connected to it. The first rolling member 71 is preferably a rubber wheel. The rubber wheel has high elasticity and can deform and quickly return to its original shape when subjected to pressure or impact. This allows the rubber wheel to effectively absorb vibration and protect the surface of the workpiece. The rubber wheel can reduce the damage of vibration to the workpiece. The rubber molecular structure is compact and resistant to friction and wear. It can maintain its performance even after long-term use on rough surfaces. The high coefficient of friction of rubber ensures that the wheel is not easy to slip when in contact with the ground. Compared with metal or hard plastic wheels, the noise generated by the rubber wheel when rolling is significantly reduced.

[0036] Along the direction of film application movement, a second rolling assembly 6 is provided in front of the first rolling assembly 7. The second rolling assembly 6 presses the film firmly onto the workpiece, so that the film is tightly attached to the workpiece. At the same time, the second rolling assembly 6 makes the film inclined in front of the first rolling assembly 7.

[0037] The second rolling assembly 6 includes a second rolling member 64, a linkage mechanism, and a second driving member 61 that drives the second rolling member 64 to move up and down. During film application, the second rolling member 64 is driven by the second driving member 61 to press the film against the workpiece. After film application, the second rolling member 64 is driven away from the workpiece by the second driving member 61, so that the film is inclined in front of the first rolling assembly 7 for easy cutting. Specifically, the second driving member 61 is suspended above the workpiece and hinged above the workpiece. The lower end of the second driving member 61 is hinged to one end of the connecting rod 62, and the other end of the connecting rod 62 is hinged to the second support member 63. The second support member 63 is hinged above the workpiece. The second rolling member 64 is rotatably mounted on the second support member 63.

The second support member 63 is preferably a support plate, with one end hinged above the workpiece and the other end hinged to the connecting rod 62. The second support member 63 is provided with a second rolling member 64 rotatably connected to it. The second rolling member 64 is preferably a rubber wheel. The rubber wheel has high elasticity and can deform and quickly return to its original shape when subjected to pressure or impact. This allows the rubber wheel to effectively absorb vibration and protect the surface of the workpiece. The rubber wheel can reduce the damage of vibration to the workpiece. The rubber molecular structure is compact and resistant to friction and wear. It can maintain its performance even after long-term use on rough surfaces. The high coefficient of friction of rubber ensures that the wheel is not easy to slip when in contact with the ground. Compared with metal or hard plastic wheels, the noise generated by the rubber wheel when rolling is significantly reduced.

[0039] The second support member 63 is also provided with a film-applying guide mechanism 4. The film-applying guide mechanism 4 includes at least a first guide roller 41, a second guide roller 42, and a third guide roller 43.

A guide member 44 is also provided between the third guide roller 43 and the second rolling member 64. A guide channel is opened on the guide member 44. The film passes through the guide channel and matches with the second rolling member 64.

[0040] A feeding roller 5 is provided near the first guide roller 41. The rolled film is installed on the feeding roller 5 and passes through the first guide roller 41, the second guide roller 42, the third guide roller 43, and the guide member 44 in sequence, and then matches with the second rolling member 64 and the first rolling member 71.

[0041] To cut and separate the film after application, a cutting component 8 is also included. The cutting component 8 is disposed on one side between the first rolling component 7 and the second rolling component 6. The cutting component 8 can extend between the first rolling component 7 and the second rolling component 6 to cut the film.

[0042] The cutting assembly 8 includes scissors 82 and a third driving member 81. The handle of the scissors 82 is connected to the third driving member 81.

[0045] To enable the first rolling assembly 7, the second rolling assembly 6, and the cutting assembly 8 to translate relative to the support platform 3, a translation mechanism is also included. This translation mechanism comprises two sets of support columns 2, each set positioned on one side of the support platform 3 along the film application direction. Each set of support columns 2 has a guide rail 9, and a crossbeam 12 spans the two guide rails 9. The crossbeam 12 is driven by a drive mechanism to reciprocate linearly along the guide rails. Preferably, the drive mechanism is a motor outputting rotary motion, which is converted into linear motion by a transmission mechanism. The transmission mechanism can employ a ball screw: balls are embedded between the screw and nut, resulting in low friction and an efficiency of 90%~96%, suitable for high-precision equipment; or a synchronous belt: a toothed belt meshes with a pulley, providing slip-free transmission, oil resistance, and wear resistance, suitable for long-distance, low-speed transmission.

[0046] The crossbeam 12 is provided with a lifting bracket 13. The first rolling assembly 7, the second rolling assembly 6, the cutting assembly 8, and the feeding roller 5 are arranged on the lifting bracket 13. The first rolling assembly 7, the second rolling assembly 6, the cutting assembly 8, and the feeding roller 5 can be lifted and lowered as a whole with the lifting bracket 13, so as to move closer to or further away from the workpiece on the support platform 3.

[0047] In one embodiment, the crossbeam 12 is provided with a vertical plate 11, the vertical plate 11 is provided with a linear guide rail, the linear guide rail is provided with a slider, the lifting bracket 13 is disposed on the slider, and the vertical plate 11 is also provided with a fifth driving member 10, the fifth driving member 10 is connected to the lifting bracket 13, and the fifth driving member 10 is any one of a cylinder, a hydraulic cylinder, or an electric cylinder. Preferably, the fifth driving member 10 is a cylinder.

[0048] To achieve alternating feeding, there are two support platforms 3, each mounted on a pair of guide rails. Specifically, the film-applying device includes a frame 1, on which two first guide rails 32 are provided along the film-applying direction. A first support platform 31 is provided on the first guide rail 32. The first support platform 31 is driven to reciprocate linearly along the guide rail by a drive mechanism. The drive mechanism is preferably a motor that outputs rotary motion, which is converted into linear motion by a transmission mechanism. The transmission mechanism can be a ball screw: balls are embedded between the screw and the nut, resulting in low friction and an efficiency of 90%~96%, suitable for high-precision equipment; or a synchronous belt: a toothed belt meshes with a pulley, providing transmission without slippage, oil resistance, and wear resistance, suitable for long-distance medium-low speed transmission.

[0049] Two second guide rails 33 are provided on the frame 1 inside the first guide rail 32 along the film application direction. A second support platform 34 is provided on the second guide rail 33. The second support platform 34 is driven to reciprocate linearly along the guide rail by a drive mechanism.

[0050] The first guide rail 32 and the second guide rail 33 have a height difference in the vertical direction, so that the first support platform 31 and the second support platform 34 can be alternately fed without interference.

[0051] The film-applying device mounts the workpiece on the support platform 3, and then the support platform 3 moves to the film-applying working area. The fifth driving component 10 drives the lifting bracket to descend, and the first rolling assembly 7, the second rolling assembly 6, the cutting assembly 8, and the feeding roller 5 move down as a whole with the lifting bracket 13. The first rolling element 71 of the first rolling assembly 7 and the second rolling element 64 of the second rolling assembly 6 press down to apply the film from the initial position of the workpiece. Then, the crossbeam 12 drives the first rolling assembly 7 and the second rolling assembly 6 to move to the end position along the film-applying direction to complete the film application. Then, the second rolling element 64 of the second rolling assembly 6 rises, so that the film is inclined in front of the first rolling assembly 7. The cutting assembly 8 can extend between the first rolling assembly 7 and the second rolling assembly 6 to cut the film. Then, the first rolling assembly 7 rises to complete the film application.

[0052] The above description is only a preferred embodiment of the present utility model.
