[0033] The embodiments of the present application are written in a progressive manner.

[0034] Please Figures 1 to 9 As shown, an embodiment of the present invention provides a rotary film tearing device, including a template frame 31, a frame 311 and an arc guide rail 312, wherein the arc guide rail 312 is fixed on the template frame 311, one side of the frame 311 cooperates with the arc guide rail 312, and the other side is hinged to the template frame 31; a frame driving mechanism 32 is also provided for driving the frame 311 to rotate along the arc guide rail 312.

[0035] In response to the problems existing in the prior art, the present application provides a rotary film-tearing device, which hinges one side of the frame 311 that fixes the texture template to the template frame 31, so that the frame 311 can rotate around the hinged axis; and the other side of the frame 311 cooperates with the arc guide rail 312 fixed on the template frame 31, and the arc guide rail 312 is used to guide the rotation of the frame 311, so that the texture template and the cured glue start to separate from the side close to the arc guide rail 312, and then the texture template and the glue are completely separated with the rotation, or by using the rotation and lifting. Compared with the operation used in the prior art of directly lifting the entire texture template vertically to separate it from the glue, the rotary film-tearing device provided by the present application simulates the operation of manual separation, starting separation from one side, causing less damage to the texture template and the cured glue, and having a higher separation efficiency. In addition, the entire process is completed mechanically, with a high degree of automation.

[0036] Preferably, the frame driving mechanism 32 is provided on a side where the frame 311 is hinged to the template frame 31 .

[0037] Preferably, the frame driving mechanism 32 includes a first power source and a rotating shaft, and the rotating shaft is connected to a side of the frame 311 .

[0038] The frame drive mechanism 32 is preferably disposed on the side of the frame 311 where it is hinged to the template frame 311 to avoid obstructing the mating of the texture template in the frame 311 with the panel. More preferably, the frame drive mechanism 32 includes a first power source and a rotating shaft, the rotating shaft being connected to the side 311 of the frame so that the rotating shaft and the side of the frame 311 are coplanar. When separation of the texture template from the glue is required, the first power source is activated to drive the rotating shaft to rotate, thereby driving the frame 311 to rotate.

[0039] The rotary film-tearing device provided herein utilizes curved guide rails 312 and a frame drive mechanism 32, respectively disposed on either side of a frame 311. This eliminates the need for occupying space above or below the texture template and casts no shadows on the texture template. Consequently, when the rotary film-tearing device provided herein is used in conjunction with other devices, the rotation of the frame 311 can be ensured to not affect the operation of the texture template mounted within the frame 311.

[0040] For example, the texture template must first be precisely positioned relative to the panel to be processed to ensure the texture effect meets the requirements. At this point, a camera is required to align the texture template and the panel. However, the curved guide rails 312 and frame drive mechanism 32 of the present application do not affect the camera's image capture or lighting. Furthermore, the processing requires rolling the texture template to ensure that the glue underneath the texture template is evenly distributed. Using the rotary film tearing device provided in the present application, rolling the texture template will not be interfered with by other structures.

[0041] Preferably, the template frame 31 is further provided with a limit block 313 , which is located below the frame 311 and is used to limit the lowest position of the frame 311 when it rotates.

[0042] A limit block 313 is preferably provided on the template frame 31 to define the lowest rotational position of the frame 311. When the rotary film tearing device provided in this application is in use, if the panel to be processed is located below the texture template, the frame 311 rotates upward during the rotary film tearing process to separate the texture template from the adhesive. When a new panel is to be processed, the texture template needs to be rotated back to its initial position. At this time, the limit block 313 defines the lowest rotational position of the frame 311, ensuring that the texture template remains horizontal after rotation and does not rotate excessively and become tilted again, thereby ensuring the quality of panel processing.

[0043] Preferably, the center of the arc-shaped guide rail 312 is located on the axis at which the frame 311 and the template frame 31 are hinged.

[0044] The function of the curved guide rail 312 is to provide guidance and a certain degree of support during the rotation of the frame 311. The length and curvature of the curved guide rail 312 are sufficient to ensure smooth rotation of the frame 311. Preferably, the arc of the curved guide rail 312 is centered on the axis of the hinge connecting the frame 311 and the formwork frame 31. This allows the curved line formed by the rotation of the edge of the curved guide rail 312 during rotation to have the same curvature as the curved guide rail 312.

[0045] Preferably, the angle between the arc-shaped guide rail 312 and the center of the circle is -15° to 15°.

[0046] The arc-shaped guide rail 312 plays a guiding and supporting role and does not need to be set very long. The length of the arc-shaped guide rail 312 is preferably converted into an angle between the arc-shaped guide rail 312 and the center of the circle of -15° to 15°, preferably -9° to 9°, which can play a guiding role without hindering the work of the texture template.

[0047] Preferably, the frame 311 cooperates with the arc-shaped guide rail 312 through a roller 314 or a slider.

[0048] Preferably, the frame 311 is provided with at least two rollers 314 , and the rollers 314 are clamped on both sides of the arc-shaped guide rail 312 .

[0049] The frame 311 and the arc guide rail 312 can be matched by sliding or rolling. Specifically, either a slider or a roller 314 can be provided.

[0050] Preferably, the frame 311 is equipped with at least two rollers 314, which are clamped on both sides of the curved guide rail 312. When the frame drive mechanism 32 is in operation, the rollers on both sides of the curved guide rail 312 rotate along the curved guide rail 312, guiding the rotation of the frame 311. More preferably, the frame 311 is equipped with 4-6 rollers 314, evenly distributed on both sides of the curved guide rail 312.

[0051] Preferably, a lifting drive mechanism 33 is further included, and the lifting drive mechanism 33 is used to drive the template frame 31 to move in the vertical direction.

[0052] Preferably, the lifting drive mechanism 33 includes a second power source, a screw rod and a lifting guide rail, the screw rod is used to transmit the power of the second power source to the template frame 31, and the lifting guide rail is used to guide the template frame 31.

[0053] Preferably, a lifting drive mechanism 33 is also provided so that the entire template frame 31 together with the frame 311, the arc guide rail 312, etc. can move in the vertical direction to better cooperate with other devices. When the texture template needs to be cleaned or replaced, it can be kept away from the processing station to facilitate operation by the operator.

[0054] Specifically, the lifting drive mechanism 33 includes a second power source, a screw rod and a lifting guide rail. The power output by the second power source causes the screw rod to rotate, thereby driving the template frame 31 to move along the lifting guide rail.

[0055] Preferably, the frame 311 clamps the texture template through a clamping member to fix the texture template. The clamping member can be two upper and lower clamping bars that cooperate with bolts to clamp the texture template. In addition, through holes can be provided on the outer edge of the texture template, and hooks can be provided on the frame 311 to fix the texture template.
