[0026] Please refer to Figures 1-5This invention illustrates a film-applying device provided in an embodiment of the present invention, comprising: a support assembly 1, a first driving member 2, a second driving member 3, a film-pressing assembly 4, and a pressing assembly 5. The first driving member 2 is disposed on the support assembly 1, and the second driving member 3 is convexly connected to the first driving member 2. The first driving member 2 is used to drive the second driving member 3 to move in the vertical direction Y. The pressing assembly 5 is connected to the second driving member 3 and is used to press the surface film onto the workpiece 9. The film-pressing assembly 4 includes a first connecting member 41, a first side film-pressing member 42, and a second side film-pressing member 43. The first side film-pressing member 42 and the second side film-pressing member 43 are movably disposed on the first connecting member 41. The first connecting member 41 is convexly connected to the second driving member 3, and the second driving member 3 is used to drive the first side film-pressing member 42 and the second side film-pressing member 43 to move in the front-back direction X.

[0027] like Figures 1-2 As shown, in this embodiment, the first driving member 2 drives the second driving member 3 to move downwards along the vertical direction Y. The pressing component 5 on the second driving member 3 moves accordingly, thereby pressing the surface film onto the upper surface of the workpiece 9 and fixing the workpiece 9 to ensure that it does not move. Then, the second driving member 3 drives the first connecting member 41 to move back and forth along the front-back direction X, so that the first side pressing member 42 and the second side pressing member 43 follow the first connecting member 41 to reciprocate back and forth, thereby pressing the surface film onto the side of the workpiece 9 to ensure the stability and consistency of the film application quality. The first side pressing member 42 and the second side pressing member 43 are movably disposed on the first connecting member 41, so that the distance between the first side pressing member 42 and the second side pressing member 43 can be adjusted according to the size of the workpiece 9, which is convenient for adapting to workpieces of various sizes and improves adaptability.

[0028] The first driving component 2 can be one of a hydraulic drive mechanism, a pneumatic drive mechanism, an electric drive mechanism, or a mechanical drive mechanism; the second driving component 3 can be one of a hydraulic drive mechanism, a pneumatic drive mechanism, an electric drive mechanism, or a mechanical drive mechanism. In this example, the first driving component 2 is a slide cylinder.

[0029] By using the pressing assembly 5, the first side pressing component 42, and the second side pressing component 43 to apply the surface film to the upper surface and sides of the workpiece 9, the film application efficiency is improved, the labor cost is reduced, and the stability and consistency of the film application quality are ensured, thereby improving the film application quality.

[0030] Optionally, the pressing assembly 5 includes a pressing member 51 and a first fixing member 52, the first fixing member 52 being disposed on the second driving member 3, and the pressing member 51 being connected to the first fixing member 52.

[0031] like Figures 1-2As shown, in this embodiment, the pressing member 51 is used to press the surface film onto the workpiece 9. Furthermore, the end of the pressing member 51 near the workpiece 9 is made of a flexible material, which can play a protective role when pressing the surface film and prevent damage to the surface film. The first fixing member 52 is a fixing seat or a fixing plate.

[0032] Optionally, the pressing assembly 5 further includes a spring-loaded member 53, which is disposed between the pressing member 51 and the first fixing member 52.

[0033] like Figures 1-2 As shown, in this embodiment, the spring-loaded member 53 is a spring or a bellows. The spring-loaded member 53 buffers the pressure generated by the first driving member 2 driving the pressing member 51 to move downward, ensuring that the surface film is pressed onto the workpiece 9 while preventing damage to the workpiece 9.

[0034] Optionally, the pressing assembly 5 further includes a guide component, which is disposed between the pressing member 51 and the first fixing member 52. The spring-loaded member 53 is sleeved on the guide component and clamped between the pressing member 51 and the first fixing member 52. The guide component is at least one of a guide stud or a pin.

[0035] Optionally, the film application device further includes a limiting member 6 and a third driving member 7. The limiting member 6 and the third driving member 7 are connected in a transmission manner. The third driving member 7 is used to drive the limiting member 6 to move in the front-back direction X. The third driving member 7 is connected in a transmission manner to the first driving member 2. The film pressing assembly 4 further includes an elastic member 44. The elastic member 44 is disposed between the first side film pressing member 42 and the second side film pressing member 43. The limiting member 6 abuts against the first side film pressing member 42 and the second side film pressing member 43 respectively.

[0036] like Figures 3-4 As shown, in this embodiment, two elastic elements 44 are provided. The front ends of the first side pressing member 42 and the second side pressing member 43 are connected by one elastic element 44, and the rear ends of the first side pressing member 42 and the second side pressing member 43 are connected by another elastic element 44. The two elastic elements 44 can provide pressing force and improve overall stability. The elastic element 44 is a tension spring. The first side pressing member 42 and the second side pressing member 43 are respectively provided with rollers. The rollers are used to roll the surface film on the side of the workpiece 9. The rollers can be made of urethane, rubber or other flexible materials to avoid scratching or damaging the workpiece and ensure good bonding.

[0037] like Figures 3-4As shown, in this embodiment, the end of the limiting member 6 away from the third driving member 7 abuts against the first side pressing member 42 and the second side pressing member 43 respectively. The width of the limiting member 6 gradually decreases from front to back in the front-rear direction X. Before the film application begins, the two frontmost sides of the limiting member 6 abut against the first side pressing member 42 and the second side pressing member 43 respectively, so that the first side pressing member 42 and the second side pressing member 43 are stretched to the maximum and respectively limited to the two ends of the first connecting member 41. When the surface film on the side of the workpiece 9 is applied, the limiting member 6 moves forward under the drive of the third driving member 7 and under the pulling force of the elastic member 44 This causes the first side-pressing member 42 and the second side-pressing member to move closer to each other, thereby pressing them onto the two sides of the workpiece 9 respectively, completing the side-pressing of the workpiece 9. After the film is applied, the limiting member 6 moves backward under the drive of the third driving member 7, the elastic member 44 is gradually stretched, the limiting member 6 returns to its original position, and the two front ends of the limiting member 6 abut against the first side-pressing member 42 and the second side-pressing member 43 respectively, so that the first side-pressing member 42 and the second side-pressing member 43 are stretched to the maximum and respectively limited to the two ends of the first connecting member 41. At the same time, the first side-pressing member 42 and the second side-pressing member 43 are separated from the workpiece 9.

[0038] The combination of the limiting component 6 and the elastic component 44 not only allows it to adapt to workpieces 9 of various sizes or irregular shapes, but the elastic component 44 can also provide pressure for film application, and realizes the automation of film application on the side of workpiece 9, further improving the overall adaptability, film application efficiency, and film application quality.

[0039] The third driving component 7 can be one of a hydraulic drive mechanism, a pneumatic drive mechanism, an electric drive mechanism, or a mechanical drive mechanism. In this embodiment, the third driving component 7 is a slide cylinder.

[0040] Optionally, the film pressing assembly 4 further includes a limiting part 45, and the first side film pressing member 42 and the second side film pressing member 43 are respectively provided with limiting parts 45, and the limiting member 6 abuts against the limiting part 45 on the first side film pressing member 42 and the limiting part 45 on the second side film pressing member 43 respectively.

[0041] like Figures 4-5 As shown, limiting portions 45 are respectively provided on the inner side between the first side pressing member 42 and the second side pressing member 43. The limiting portions 45 can be protrusions or cams extending from the first side pressing member 42 and the second side pressing member 43, or they can be limiting wheels respectively provided on the inner side between the first side pressing member 42 and the second side pressing member 43. The cooperation of the limiting portions 45 enables the limiting member 6 to be better limited, which is beneficial to the overall stability.

[0042] Optionally, such as Figure 5As shown, the film pressing assembly 4 also includes a first guide rail 46, which is disposed on the first connector 41. The first side film pressing component 42 and the second side film pressing component 43 are movably connected to the first guide rail 46.

[0043] Optionally, such as Figures 1-4 As shown, the film application device also includes a second connector 31, which is fixedly connected to the second drive member 3 and is also connected to the first drive member 2 via transmission.

[0044] Optionally, such as Figures 1-4 As shown, the film application device also includes a third connector 71, which is fixedly connected to the third drive member 7 and is also connected to the first drive member 2 in a transmission manner. The third connector 71 is also fixedly connected to the second connector 31.

[0045] Optionally, such as Figure 5 As shown, the film application device also includes a second guide rail 8, which is disposed between the second connector 31 and the second drive member 3, and the first connector 41 is movably connected to the second guide rail 8.

[0046] Optionally, such as Figures 1-2 As shown, the support assembly 1 includes a bracket 11 and a second fixing member 12. The second fixing member 12 is disposed on the bracket 11, and the first driving member 2 is disposed on the second fixing member 12. The cooperation between the second fixing member 12 and the bracket 11 is beneficial to the overall stability.

[0047] The working principle of the film application device provided in this application is as follows:

[0048] When applying the film to the workpiece 9 on the fixture, the first driving member 2 simultaneously drives the second connecting member 31 and the third connecting member 71 to move downwards in the vertical direction Y, thereby causing the second driving member 31 and the third driving member 71 to move downwards as a whole. The pressing member 51 follows and moves downwards, thereby pressing the surface film onto the upper surface of the workpiece 9, pressing and fixing the workpiece 9 to ensure that the workpiece 9 does not move. The spring member 53 acts as a buffer. The limiting member 6 moves forward under the drive of the third driving member 7, and the parts that were originally opened by the limiting member 6 and respectively limited to the upper surface of the workpiece 9 are now in a state of tension. Under the tension of the elastic member 44, the first side pressing member 42 and the second side pressing member 43 at both ends of the connector 41 move closer to each other on the first guide rail 46, thereby pressing them onto the two sides of the workpiece 9 respectively. The second driving member 3 drives the first connector 41 to move back and forth along the front-back direction X on the second guide rail 8, thereby driving the first side pressing member 42 and the second side pressing member 43 to reciprocate back and forth, thereby pressing the surface film onto the two sides of the workpiece 9.

[0049] When the surface film is applied to the workpiece 9, the second driving member 3 stops driving the first connecting member 41, the first side film pressing member 42 and the second side film pressing member 43 stop moving, the limiting member 6 moves backward under the drive of the third driving member 7, the elastic member 44 is gradually stretched, the limiting member 6 gradually returns to its original position, and the first side film pressing member 42 and the second side film pressing member 43 move away from each other on the first guide rail 46 until the two sides of the foremost end of the limiting member 6 are respectively limited by the first side film pressing member 42 and the second side film pressing member 43. Part 45 abuts, causing the first side pressing member 42 and the second side pressing member 43 to be stretched to their maximum and respectively limited to both ends of the first connecting member 41. At the same time, the first side pressing member 42 and the second side pressing member 43 are separated from the workpiece 9. The first driving member 2 simultaneously drives the second connecting member 31 and the third connecting member 71 to move upward in the vertical direction Y, thereby driving the second driving member 3 and the third driving member 7 to move upward as a whole. The pressing member 51 follows and moves upward, thereby separating from the workpiece 9 and completing the overall film application work.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
