[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0022] See also Figure 1 、 Figure 2The present invention provides a LAMI device contour carrier film clamping device 100, comprising a mounting platform 110, a mounting frame 120, and a clamp assembly 130. The mounting frame 120 is mounted on the mounting platform 110, and the clamp assemblies 130 are disposed on each side of the mounting frame 120 to clamp the four sides of the carrier film 300.

[0023] The clamp assembly 130 includes a vertical lift platform 131, a horizontal movable platform 132, a clamping member 133, and an elastic member 134. The base 1311 of the vertical lift platform 131 is mounted on the mounting platform 110. The movable portion of the vertical lift platform 131 can rise and fall along the side of the mounting frame 120. The horizontal movable platform 132 is mounted on the movable portion of the vertical lift platform 131. The movable portion of the horizontal movable platform 132 can move along the normal direction of the side of the mounting frame 120 on which it is located. The clamping member 133 is connected to the movable portion of the horizontal movable platform 132 via an elastic member 134.

[0024] The structure of the carrier film 300 is shown in FIG. Figure 3 The middle part of the carrying film 300 is the display component carrying part 310 , and the surrounding parts are the clamping parts 320 .

[0025] See also Figure 4 Before profiling, the carrier film 300 is clamped around its perimeter by the clamping components 133 of the clamp assembly 130 and positioned on the profiling jig 220. During profiling, the clamping components 133 of the clamp assembly 130 are driven downward by the movable portion of the vertical lift platform 131 and toward the center of the carrier film 300 by the movable portion of the horizontal movable platform 132. This causes the display component support portion 310 of the carrier film 300 to be stretched and pressed against the edge of the profiling jig 220, forming an arc-shaped edge.

[0026] In the embodiment of the present invention, an elastic component 134 is provided between the movable part of the horizontal moving platform 132 and the movable part of the vertical lifting platform 131, so that there is a certain buffer when the movement of the movable part of the vertical lifting platform 131 and the movable part of the horizontal moving platform 132 is transmitted to the clamping component 133. Each side clamp assembly 13 of the mounting frame 12 is also provided with an elastic component 134, which can make the clamping force around the carrier film 300 more balanced, and can avoid to a certain extent the damage of the carrier film 300 during the contouring movement, thereby improving product yield and production efficiency.

The first transmission mechanism 1313 includes a screw rod 13131 and a screw rod nut 13132. The screw rod 13131 is arranged on the base 1311 of the vertical lifting platform 131, and the screw rod nut 13132 is fixedly arranged on the lifting movable platform 1314.

[0029] In a specific implementation, the screw rod 13131 is arranged longitudinally, and the first power source 1312 is arranged on the base 1311. The rotating output shaft of the first power source 1312 can rotate the screw rod 13131 through a belt, gear or direct coupling, thereby causing the screw rod nut 13132 and the lifting movable platform 1314 fixedly connected to the screw rod nut 13132 to rise or fall.

[0030] In some embodiments, the first power source 1312 is a servo motor.

The second transmission mechanism 1322 includes a gear 13221 and a rack 13222. The gear 13221 is set on the lifting movable platform 1314, and the rack 13222 is horizontally fixed on the horizontal movable platform 1323. The second power source 1321 can drive the gear 13221 to rotate so that the horizontal movable platform 1323 moves horizontally.

[0033] In a specific implementation, the extension direction of the rack 13222 is parallel to the normal direction of the side of the mounting frame 120. The second power source 1321 is set on the lifting movable platform 1314. The rotation output shaft of the second power source 1321 is directly coupled with the central axis of the gear 13221, thereby driving the gear 13221 to rotate, so that the horizontal movable platform 1323 fixedly connected to the rack 13222 is rotated. In some embodiments, the second power source 1321 is a servo motor.

[0034] In some embodiments, a second slide rail is provided on the top surface of the lifting movable platform 1314 , and the horizontal movable platform 1323 can slide on the second slide rail via a second slider 13231 fixed to the horizontal movable platform 1323 .

[0035] In some embodiments, the clamping component 133 is disposed on the clamping movable platform 135 , and the clamping movable platform 135 is connected to the horizontal movable platform 1323 via the elastic component 134 .

[0036] In some embodiments, a third slide rail 13232 is provided on the top surface of the horizontal movable platform 1323 , and the clamping movable platform 135 can slide on the third slide rail 13232 via a third slider 1351 fixed to the clamping movable platform 135 .
