[0034] like Figure 1-4As shown, to address the problem of the existing film-peeling mechanism 3 having a complex structure and the material feeding device occupying space, thus increasing its size, this invention provides a film-applying device, comprising: a workpiece placement mechanism 2, which is provided with a workpiece placement platform 23, the workpiece placement platform 23 being configured to place a workpiece 6; and a film-peeling mechanism 3, which includes a support plate 31, a fixing clamp 32, a moving clamp 33, a material feeding turntable 34, and adhesive tape 35 wound on the material feeding turntable 34; the fixing clamp 32 is fixedly connected to the support plate 31. The fixed clamp 32 is configured to clamp the adhesive tape 35, and the movable clamp 33 is configured to clamp the adhesive tape 35 and move along the width direction of the support plate 31; the feeding turntable 34 is rotatably mounted on the support plate 31; the adhesive tape 35 between the fixed clamp 32 and the movable clamp 33 is configured to adhere the protective film on the film sheet; the gripping mechanism 4, connected to the support plate 31, is configured to grip the film sheet onto the adhesive tape 35 between the fixed clamp 32 and the movable clamp 33 or onto the workpiece 6. Thus, this film-applying equipment, by integrating the workpiece placement mechanism 2, the film-tearing mechanism 3, and the gripping mechanism 4, simplifies the film-applying process, reduces the equipment size, and improves operational efficiency. The film-tearing mechanism 3, using the design of the fixed clamp 32 and the movable clamp 33 in conjunction with the adhesive tape 35, can efficiently separate the film sheet and the protective film, solving the problems of complex structure and large space occupation in the prior art.

[0035] like Figure 1 and Figure 2 As shown, in one or more embodiments, the film-applying device includes a base 1, with support feet disposed on the lower side of the base 1, and a cavity formed within the base 1. This allows relevant components to be placed within the cavity. Alternatively, the base 1 can also employ other structures, such as a bracket.

[0036] like Figure 1 As shown, in one or more embodiments, the workpiece placement mechanism 2 includes a placement disk drive 21, a placement disk 22, and a workpiece placement stage 23. The placement disk drive 21 is electrically driven. Alternatively, it can be driven by an air pump. The placement disk 22 is disc-shaped and connected to the drive end of the placement disk drive 21, which is configured to drive the placement disk 22 to rotate. Alternatively, the placement disk 22 can be polygonal. There are four workpiece placement stages 23, spaced apart along the rotation direction of the placement disk 22. Thus, the workpiece placement mechanism 2, through the design of the placement disk drive 21 and multiple workpiece placement stages 23, achieves rapid switching and continuous operation of the workpiece 6, improving the overall production efficiency of the equipment. It should be noted that those skilled in the art can select the number of workpiece placement stages 23 based on specific application scenarios. There can be multiple workpiece placement stages 23, for example, two, three, five, etc.

[0037] like Figure 1 and Figure 4As shown, the film-tearing mechanism 3 includes a support plate 31, a fixing clamp 32, a clamp guide rail 38, a moving clamp 33, a turntable drive 36, a feeding turntable 34, and adhesive tape 35 wound on the feeding turntable 34. The lower end of the support plate 31 is fixedly connected to the upper end of the base 1. Figure 4 As shown, a groove is formed in the lower middle position of the support plate 31 in the left-right direction. A fixing clamp 32 is fixedly connected to the support plate 31. The fixing clamp 32 includes a clamping drive and two clamping heads. The clamping drive can drive the two clamping heads to clamp or release the tape 35. The structure of the clamping drive is prior art and will not be described in detail here. Figure 2 As shown, in one or more embodiments, the clamp guide rail 38 is fixedly connected to the support plate 31, and the clamp guide rail 38 is along the width direction of the support plate 31. Figure 2 The clamp guide rail 38 is arranged along its length, and the movable clamp 33 is slidably connected to the clamp guide rail 38. The movable clamp 33 is configured to clamp the tape 35 and is positioned along the width direction of the support plate 31. Figure 2 The clamp guide rail 38 moves along the length direction of the clamp. The clamp guide rail 38 allows the moving clamp 33 to move smoothly along the width direction of the support plate 31, further improving the accuracy and efficiency of clamping the tape 35 and reducing the equipment failure rate. Figure 4 As shown, in one or more embodiments, the turntable drive 36 is located on one side of the support plate 31 and is fixedly connected to the support plate 31. The feeding turntable 34 is provided with an annular groove for winding the tape 35. The feeding turntable 34 is located on the other side of the support plate 31 and is connected to the drive end of the turntable drive 36. By setting the feeding turntable 34 and the turntable drive 36, automatic feeding of the tape 35 is achieved, further simplifying the operation steps, improving the automation level of the equipment, and reducing manual intervention. At the same time, the feeding turntable 34 can provide a certain pre-tension to the tape 35, preventing the tape 35 from knotting after discharge.

[0038] like Figure 1 As shown, in one or more embodiments, the film-peeling mechanism 3 further includes a guide shaft 37, which is rotatably connected to the support plate 31, and the adhesive tape 35 is pressed against the guide shaft 37. The design of the guide shaft 37 ensures the stability and accuracy of the adhesive tape 35 during movement, preventing the adhesive tape 35 from shifting or loosening, and improving the quality and consistency of film application. It should be noted that the inclusion of the guide shaft 37 is not mandatory. Those skilled in the art can choose whether to include the guide shaft 37 and its specific structure based on the specific application scenario; of course, the guide shaft 37 can also be omitted.

The guide rail drive 53 is connected to the guide rail frame 51 and is configured to drive the movable seat 52 to move. Thus, the combined design of the guide rail frame 51, the movable seat 52, and the guide rail drive 53 enables precise movement of the gripping mechanism 4, improving the automation level and efficiency of the film application operation. Alternatively, the guide rail drive 53 can also be connected to the movable seat 52, as long as it can drive the gripping mechanism 4 to move in a direction approximately perpendicular to the support plate 31.

[0040] like Figure 3 As shown, in one or more embodiments, the gripping mechanism 4 includes a gripper drive 42 and a gripping head 41. The fixed end of the gripper drive 42 is connected to the movable seat 52, and the gripping head 41 is provided on the movable end of the gripper drive 42. The gripping head 41 is configured to grip the film. Thus, the design of the gripper drive 42 and the gripping head 41 enables the film to be accurately gripped and placed, further improving the accuracy and efficiency of film application and reducing operational errors. It should be noted that the gripping head 41 grips the film using a negative pressure adsorption method; the specific structure is existing technology and will not be described in detail here. Alternatively, the configuration of the gripping mechanism 4 is not unique; those skilled in the art can choose the specific structure of the gripping mechanism 4 based on the specific application scenario. As long as the film can be gripped, the film can be first gripped onto the tape 35 to remove the protective film, and then the film can be gripped onto the workpiece 6 to apply the film to the workpiece 6.

[0041] like Figure 3 As shown, in one or more embodiments, the gripping head 41 is located away from the side of the support plate 31. Figure 3 A pressing assembly is provided on the side of the film closest to the paper surface. The pressing assembly includes a pressing drive 81, a pressure roller connecting frame 82, and a pressure roller 83.

The pressure roller 83 is configured to press the film on the workpiece 6. In this way, the setting of the pressing assembly ensures that the film can be evenly pressed during the application process, avoiding the generation of air bubbles or wrinkles and improving the quality of film application. It should be noted that the setting of the pressing assembly is not mandatory. Those skilled in the art can choose whether to set the pressing assembly and the specific structure of the pressing assembly based on the specific application scenario. Of course, the pressing assembly can also be omitted.

[0042] like Figure 2 and Figure 4As shown, in one or more embodiments, the film-applying device further includes a pressure knife holder 71, a pressure knife drive, and a pressure knife 72. The pressure knife holder 71 is fixedly mounted on the base 1. The fixed end of the pressure knife drive is connected to the pressure knife holder 71.

The upper end of the pressure knife 72 is sharpened, and the upper end of the pressure knife 72 can cut the adhesive tape 35 between the fixed clamp 32 and the movable clamp 33. It should be noted that the setting of the pressure knife 72 is not necessary. Those skilled in the art can choose whether to set the pressure knife 72 and the specific structure of the pressure knife 72 based on the specific application scenario. Of course, the pressure knife 72 can also be omitted, and correspondingly, the pressure knife holder 71 and the pressure knife drive can also be omitted.
