[0028] like Figure 6 As shown, the workpiece 90 includes a straight edge 91, an arc edge 92, a first side edge 93, a second side edge 94, an upper surface 95, and a lower surface. The first side edge 93 and the second side edge 94 are arranged opposite each other from left to right, and the upper surface 95 and the lower surface are arranged opposite each other from top to bottom. The straight edge 91 is connected to the first side edge 93 and the second side edge 94 through the arc edge 92 respectively.

[0029] Please refer to Figures 1-5This illustration shows a coating device provided in an embodiment of the present invention, comprising: a first support assembly 10, a second support assembly 20, a first driving member 30, a second driving member 40, a pressing assembly 50, a first film pressing assembly 60, a third driving member 70, and a second film pressing assembly 80. The first driving member 30 is disposed on the first support assembly 10, and the second driving member 40 is convexly connected to the first driving member 30. The first driving member 30 is used to drive the second driving member 40 to move in the vertical direction Y. The pressing assembly 50 is connected to the second driving member 40 and is used to press the surface film onto the workpiece 90. The first film pressing assembly 60 includes a first connecting member 61 and a straight edge 9 for pressing the surface film onto the workpiece 90. The straight-edge pressing component 62 on the second support assembly 20 is connected to the second driving component 40 via the first connecting component 61. The second driving component 40 is used to drive the straight-edge pressing component 62 to move in the front-back direction X. The third driving component 70 is disposed on the second support assembly 20. The second pressing assembly 80 includes the second connecting component 81, the first arc-edge pressing component 82 and the second arc-edge pressing component 83. The second connecting component 81 is connected to the third driving component 70. The first arc-edge pressing component 82 and the second arc-edge pressing component 83 are rotatably disposed on both sides of the end of the second connecting component 81 away from the third driving component 70. The third driving component 70 is used to drive the first arc-edge pressing component 82 and the second arc-edge pressing component 83 to move in the front-back direction X.

[0030] like Figures 1-3 As shown, in this embodiment, the pressing assembly 50 is fixedly connected to the second driving member 40. The pressing assembly 50 is used to press the surface film onto the upper surface 95 of the workpiece 90. The first connecting member 61 is drively connected to the second driving member 40. The third driving member 70 is used to drive the first arc-edge pressing member 82 and the second arc-edge pressing member 83 to move along the front-rear direction X through the first support assembly 10. The first arc-edge pressing member 82 and the second arc-edge pressing member 83 are respectively used to press the surface film onto the arc edge 92 of the workpiece 90.

[0031] The first driving component 30 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 40 can be one of a hydraulic drive mechanism, a pneumatic drive mechanism, an electric drive mechanism, or a mechanical drive mechanism; the third driving component 70 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 30 is a slide cylinder. The straight-edge pressing component 62 includes rollers and bearings. The rollers are connected to the first connecting component 61 through the bearings. The rollers are used to roll the surface film on the straight edge 91. The rollers can be made of urethane, rubber, or other flexible materials to avoid scratching or damaging the workpiece and ensure a good bonding rate.

[0032] The first driving member 30 drives the second driving member 40 to move downwards in the vertical direction Y. The pressing component 50 and the straight-edge pressing component 62 on the second driving member 40 move accordingly. Thus, the pressing component 50 presses the surface film onto the upper surface 95 of the workpiece 90, while fixing the workpiece 90 to ensure that it does not move. At the same time, the straight-edge pressing component 62 also presses the surface film onto the straight edge 91 of the workpiece 90 during the downward pressing process. Then, the second driving member 40 drives the first connecting member 61 to move backwards in the front-back direction X, so that the straight-edge pressing component 62 moves away from the workpiece 90. The first driving member 30 drives the second driving member 40 to move upwards in the vertical direction Y, causing the pressing component 50 and the straight-edge pressing component 62 to move accordingly. The pressing component 50 disengages from the workpiece 90 and returns to its original position. The second driving member 40... The first connecting member 61 is driven to move forward along the front-rear direction X, and the straight-edge pressing member 62 moves and returns to its original position. Then, the third driving member 70 drives the first arc-edge pressing member 82 and the second arc-edge pressing member 83 to move forward along the front-rear direction X through the first support assembly 10. This causes the first arc-edge pressing member 82 and the second arc-edge pressing member 83 to contact the arc-edge 92 of the workpiece 90, rotate, and adhere to the arc-edge 92. They continue to move forward, pressing the surface film onto the arc-edge 92 of the workpiece 90. Finally, the third driving member 70 drives the first arc-edge pressing member 82 and the second arc-edge pressing member 83 to move backward along the front-rear direction X. During the process of detaching from the arc-edge 92 of the workpiece 90, a second pressing is performed, making the surface film adhere more firmly to the arc-edge 92. Finally, the first arc-edge pressing member 82 and the second arc-edge pressing member 83 return to their original positions. By first driving the straight-edge pressing member 62 to detach from the workpiece 90 and then driving the pressing assembly 50 to detach from the workpiece 90, the workpiece 90 can be prevented from being pulled away from the workstation, which would affect subsequent processing.

[0033] By using the pressing assembly 50, the straight edge pressing component 62, the first arc edge pressing component 82, and the second arc edge pressing component 8 together, the surface film can be simultaneously applied to the upper surface 95, the straight edge 91, and the arc edge 92 of the workpiece. This not only improves the film application efficiency and reduces labor costs, but also ensures the stability and consistency of the film application quality, thereby improving the film application quality.

[0034] Optionally, the pressing assembly 50 includes a pressing member 51 and a first fixing member 52, the first fixing member 52 being disposed on the second driving member 40, and the pressing member 51 being connected to the first fixing member 52.

[0035] like Figures 1-2 As shown, in this embodiment, the pressing member 51 is used to press the surface film onto the upper surface 95 of the workpiece 90. Specifically, the end of the pressing member 51 near the workpiece 90 is made of a flexible material, which can play a protective role during the pressing of the surface film and prevent damage to the surface film. The first fixing member 52 is a fixing seat or a fixing plate.

[0036] Optionally, the pressing assembly 50 further includes a spring-loaded member 53 disposed between the pressing member 51 and the first fixing member 52.

[0037] like Figures 1-2 As shown, in this embodiment, the spring 53 is a spring or a bellows. The spring 53 buffers the pressure generated by the first driving member 30 driving the pressing member 51 to move downward, ensuring that the surface film is pressed onto the workpiece 90 while preventing damage to the workpiece 90.

[0038] Optionally, the pressing assembly 50 further includes a guide member disposed between the pressing member 51 and the first fixing member 52, and a spring-loaded member 53 sleeved on the guide member and clamped between the pressing member 51 and the first fixing member 52. The guide member is at least one of a guide stud or a pin.

[0039] Optionally, the coating device further includes a second fixing member 41, a third connecting member 42, and a third fixing member 43. The second fixing member 41 is connected to the first driving member 30 in a transmission manner.

The second driving member 40 passes through the third fixing member 43 and is connected to the first driving member 30 in a transmission manner through the second fixing member 41.

[0040] like Figures 2-3 As shown, in this embodiment, the second fixing member 41 is disposed on the first driving member 30 and is connected to the first driving member 30 in a transmission manner. Specifically, the first fixing member 52 is fixedly connected to the second driving member 40 through the third fixing member 43.

[0041] Optionally, the coating device further includes a first limiting member 44 for limiting the displacement of the straight edge pressing member 62 in the front-rear direction X and a second limiting member 45 for limiting the displacement of the straight edge pressing member 62 in the front-rear direction X. The first limiting member 44 is inserted through the third fixing member 43, and the second limiting member 45 is disposed on the second fixing member 41. The first limiting member 44 and the second limiting member 45 are disposed opposite to each other.

[0042] like Figures 2-3 As shown, in this embodiment, the first limiting member 44 is used to restrict the straight-edge pressing member 62 from moving forward, and plays a role in buffering and limiting. The second limiting member 45 is used to restrict the straight-edge pressing member 62 from moving backward. The second limiting member 45 is a limiting screw.

[0043] Optionally, such as Figures 2-3 As shown, the first pressing assembly 60 also includes a first guide rail 63, which is disposed between the third fixing member 43 and the second fixing member 41, and the first connecting member 61 is movably connected to the first guide rail 63.

[0044] Optionally, the second pressing assembly 80 further includes an elastic element 84, which is disposed between the first arc-edge pressing member 82 and the second arc-edge pressing member 83.

[0045] like Figures 4-5 As shown, the elastic element 84 can provide pressing force without damaging the workpiece 90 and improves overall stability. In this embodiment, the elastic element 84 is a tension spring. The first arc-edge pressing element 82 and the second arc-edge pressing element 83 are respectively provided with rollers. The rollers are used to roll the surface film on the arc edge 92. The rollers can be made of urethane, rubber or other flexible materials to avoid scratching or damaging the workpiece and ensure a good bonding rate.

[0046] Optionally, the second pressing assembly 80 further includes a third limiting member 85, which is disposed at the end of the second connector 81 away from the third driving member 70 and located between the first arc-edge pressing member 82 and the second arc-edge pressing member 83.

[0047] like Figures 4-5 As shown, the displacement of the first arc-edge pressing member 82 and the second arc-edge pressing member 83 under the pulling force of the elastic member 84 can be controlled by the third limiting member 85, thus ensuring the overall stability.

[0048] Optionally, such as Figures 1-2 As shown, the first support assembly 10 includes a first base 11, a first bracket 12 and a fourth fixing member 13. The first bracket 12 is disposed on the first base 11, the fourth fixing member 13 is disposed on the first bracket 12, and the first driving member 30 is disposed on the fourth fixing member 13.

[0049] Optionally, such as Figures 1-2 and Figure 4 As shown, the second support assembly 20 includes a second base 21, a second bracket 22 and a fifth fixing member 23. The second bracket 22 is disposed on the second base 21, the fifth fixing member 23 is disposed on the second bracket 22, and the third driving member 70 is disposed on the fifth fixing member 23.

[0050] The working principle of the coating device provided in this application is as follows:

[0051] When applying the film to the workpiece 90 on the fixture, the first driving member 30 drives the second fixing member 41 to move downwards in the vertical direction Y. The second driving member 40 moves downwards accordingly. At this time, the first connecting member 61 abuts against the first limiting member 44. The pressing member 51 and the straight edge pressing member 62, which are fixedly connected to the second driving member 40, move downwards accordingly. Thus, the pressing member 51 presses the surface film onto the upper surface 95 of the workpiece 90, while fixing the workpiece 90 to ensure that the workpiece 90 does not move. The spring member 53 plays a buffering role, and the straight edge pressing member 62 also acts as a buffer during the downward pressing process. During the process, the surface film is pressed onto the straight edge 91 of the workpiece 90. After the film is applied to the straight edge 91, the second driving member 40 drives the first connecting member 61 to move backward in the front-back direction X, so that the straight edge film pressing member 62 moves away from the workpiece 90 until the first connecting member 61 abuts against the second limiting member 45. The first driving member 30 drives the second fixing member 41 to move upward in the vertical direction Y. The second driving member 40 moves upward, causing the pressing member 51 and the straight edge film pressing member 62 to move upward as well. The pressing member 51 detaches from the workpiece 90 and returns to its original position. The second driving member 40 then drives the second fixing member 41 to move upward. The first connecting member 61 moves forward along the front-rear direction X, then returns to its original position and abuts against the first limiting member 44. The straight-edge pressing member 62 moves and returns to its original position. Then, the third driving member 70 drives the first arc-edge pressing member 82 and the second arc-edge pressing member 83 to move forward along the front-rear direction X through the first bracket 12. This causes the first arc-edge pressing member 82 and the second arc-edge pressing member 83 to contact the arc edge 92 of the workpiece 90, begin to rotate, and continue to move forward, adhering to the arc edge 92. Under the pressure of the elastic member 84, the surface film is pressed onto the arc edge 92 of the workpiece 90. 2. After the first pressing of the arc edge 92 is completed, the third driving member 70 drives the first arc edge pressing member 82 and the second arc edge pressing member 83 to move backward in the front-back direction X. During the process of separating from the arc edge 92 of the workpiece 90, the second pressing is performed, so that the surface film is pressed more firmly on the arc edge 92. Finally, the first arc edge pressing member 82 and the second arc edge pressing member 83 separate from the workpiece 90 and return to their positions. At the same time, the third limiting member 85 restricts the displacement of the first arc edge pressing member 82 and the second arc edge pressing member 83 under the pulling force of the elastic member 84, ensuring the overall stability.
