[0034] The following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0035] The following describes the transfer platform 100 and the film mounting device of the present utility model with reference to the accompanying drawings.

[0036] As Figures 1 to 3 shown, the present utility model provides a transfer platform 100, which includes a frame body 110 and a pressing module; the frame body 110 encloses a hollow area 120, a groove 130 surrounding the hollow area 120 is provided on the frame body 110, and a first sealing surface 131 is provided on one side of the groove 130 close to the hollow area 120; the pressing module includes a pressing adjustment member 140 and a pressing block 150, the pressing block 150 is arranged in the groove 130, a second sealing surface 151 that abuts and cooperates with the first sealing surface 131 is provided on one side of the pressing block 150 facing the hollow area 120, and the pressing adjustment member 140 is arranged on the frame body 110 and abuts against the side of the pressing block 150 facing away from the hollow area 120.

[0037] When clamping the film, the operator first lays the transfer film 500 flat on the frame body 110, and then presses the edge of the film 500 into the groove 130 by using the pressing block 150. Since the groove 130 is arranged around the hollow area 120, when pressing down the pressing block 150, all four sides of the film 500 are subjected to a certain pulling force, so that the film 500 is tensioned. Finally, the pressing adjustment member 140 is used to make the pressing block 150 tightly fit with the groove 130 to clamp the film 500, so as to ensure that the film 500 is evenly attached to the frame body 110 and keep the film 500 in a uniformly tensioned state.

[0038] When applying the transfer operation for product printing, the transfer platform 100 and the film 500 can be placed together in the corresponding printing equipment. The film 500 in a uniformly tensioned state can be flatly attached to the curved surface product, thereby improving the printing accuracy and product quality.

[0039] It should be noted that the first sealing surface 131 can also be arranged on the side facing away from the hollow area 120. By correspondingly changing the driving direction of the pressing adjustment member 140 on the pressing block 150, the effect of keeping the film 500 in a uniformly tensioned state can also be achieved; or both sides of the groove 130 can be set as the first sealing surface 131.

[0040] Specifically, the adhesive film 500 is arranged in a rectangular shape, and the frame body 110 is also correspondingly arranged as a surrounding frame with a rectangular structure. The groove 130 includes four groove segments sequentially arranged along the four sides of the frame body 110. Each groove segment is formed with a first sealing surface 131. The number of the pressing blocks 150 is also correspondingly set to four for being placed in the four groove segments one by one. Of course, the present invention is not limited thereto. According to the actual shape of the adhesive film 500, the frame body 110 can be set to other outer shape structures. However, considering that rectangular adhesive films 500 are mostly used in the actual printing process, in the following embodiments, the transfer platform 100 and the adhesive film installation device are both set for the rectangular adhesive film 500.

[0041] In the embodiment of the present invention, the pressing adjustment member 140 is set as an adjustment bolt penetrating through the frame body 110. A plurality of threaded holes communicating with the groove 130 are arranged at intervals on the frame body 110. The number of the pressing adjustment members 140 is also set corresponding to the number of the threaded holes. By screwing the pressing adjustment member 140, the pressing block 150 can be fixed or loosened, and the pressing adjustment member 140 can be integrally placed in the threaded holes and the groove 130 without protruding from the frame body 110, avoiding scratching with other devices during the transportation process. Of course, the present invention is not limited thereto. In other embodiments of the present invention, the pressing adjustment member 140 can also be set as a pneumatic or electric push rod. By connecting a gas source or a power source, the automatic pressing or loosening of the pressing block 150 can be realized to improve the assembly efficiency of the transfer platform 100.

[0042] As Figure 1 shown, in the embodiment of the present invention, the first sealing surface 131 is inclined upwardly away from the hollow area 120, and the second sealing surface 151 is a wedge surface. The first sealing surface 131 and the bottom wall of the groove 130 form a space similar to a dovetail groove. When the pressing adjustment member 140 presses the pressing block 150, the pressing block 150 gradually wedges in and squeezes the inclined adhesive film 500 close to the first sealing surface 131. Compared with a straight groove, a surface sealing contact on four sides can be formed more easily, ensuring the uniform tight fit between the adhesive film 500 and the frame body 110.

[0043] In the embodiment of the present invention, the pressing block 150 has the same length as the first sealing surface 131. Any area on the edge of the adhesive film 500 can be subjected to the pulling force of the pressing block 150, thereby further improving the uniformity of the tension of the adhesive film 500. Specifically, the shape of the first sealing surface 131 of each groove segment is trapezoidal, and the shape of the pressing block 150 is also set corresponding to the first sealing surface 131.

[0044] As Figure 1 、 Figure 3 and Figure 4As shown, in order to achieve the above-mentioned objectives, the utility model also provides a film installation device, including a frame 200, a film drawing module 300 and the above-mentioned transfer platform 100, the transfer platform 100 is placed on the frame 200, the film drawing module 300 is arranged on the periphery of the transfer platform 100, and the film drawing module 300 includes a film clamping mechanism 310. Before performing the printing operation, the operator places the transfer platform 100 on the frame 200, then lays the film 500 flat, and clamps and fixes the edge of the film 500 through the film clamping mechanism 310, then moves the film drawing module 300 as a whole to make the film 500 initially tensioned, then presses the pressing block 150 into the groove 130 to achieve secondary tensioning of the film 500, and finally takes out the transfer platform 100 and transfers it to the corresponding printing station. The film drawing module 300 can freely and automatically adjust the tension of the film 500 to adapt to different models or different sizes of films 500. For example, the tension of the adhesive film 500 of different thicknesses under the same stretching length is different, and the secondary stretching length of the adhesive film 500 caused by the downward pressure of the pressing block 150 is certain. Then, the overall stretching length of the adhesive film 500 can be adjusted through the film stretching module 300, so that the tension of the adhesive film 500 is in the most appropriate state, further improving the printing accuracy and product quality.

[0045] Please also read Figure 5 In an embodiment of the utility model, the film installation device also includes a film supporting module 400, which includes a lifting drive component 410 and a film supporting plate 420. The lifting drive component 410 is arranged on the lower side of the transfer platform 100 and is transmission-connected to the film supporting plate 420. The film supporting plate 420 is arranged corresponding to the hollow area 120. After the operator spreads the adhesive film 500 flat on the frame 110, the lifting drive member 410 drives the film-supporting plate 420 to rise, so that the upper surface of the film-supporting plate 420 is flush with the upper surface of the frame 110, and then the film-supporting plate 420 and the frame 110 can flatten the entire adhesive film 500, and then move the film-drawing module 300 to initially tension the adhesive film 500. After the adhesive film 500 is initially tensioned, the lifting drive member 410 drives the film-supporting plate 420 to descend, and the operator can place the tension meter at the position corresponding to the hollow area 120 on the adhesive film 500 to detect the tension of the adhesive film 500. When the tension meets the requirements, the pressing block 150 is placed in the groove 130, and the clamping adjustment member 140 is locked, so that the four sides of the tensioned adhesive film 500 can be pressed against the frame 110. It should be noted that when the tensioning module film-pulling module 300 initially tensions the adhesive film 500, it is necessary to reserve a pressure that is increased after the pressing block 150 is pressed down, and the specific value can be obtained through experiments.

[0046] like Figure 4 and Figure 6As shown, in the embodiment of the present utility model, the film pulling module 300 further includes a tension driving assembly 320. The tension driving assembly 320 is arranged on the frame 200 and is in transmission connection with the film clamping mechanism 310 to automatically tension the adhesive film 500. Compared with the manual tensioning solution, the tension of the adhesive film 500 can be controlled more accurately. Of course, the present utility model is not limited thereto. The film pulling module 300 can also be provided with two fitting and rolling rubber rollers, and the adhesive film 500 is clamped between the two rubber rollers. Rotating the rubber rollers can tension the adhesive film 500.

[0047] As Figure 4 and Figure 6 shown, in the embodiment of the present utility model, the film pulling module 300 includes two film clamping mechanisms 310 respectively arranged on opposite sides of the transfer platform 100 along the first horizontal direction, and two film clamping mechanisms 310 respectively arranged on opposite sides of the transfer platform 100 along the second horizontal direction. The tension driving assembly 320 includes a first horizontal driving mechanism and a second horizontal driving mechanism. The first horizontal driving mechanism is in transmission connection with the two film clamping mechanisms 310 arranged along the first horizontal direction, and the second horizontal driving mechanism is in transmission connection with the two film clamping mechanisms 310 arranged along the second horizontal direction. Optionally, the first horizontal direction is Figure 6 the X-axis direction as shown, and the second horizontal direction is Figure 6 the Y-axis direction as shown. The first horizontal direction is perpendicular to the second horizontal direction, so as to uniformly stretch the rectangular adhesive film 500 in two mutually perpendicular directions. For adhesive films 500 of other shapes, horizontal driving mechanisms and film clamping mechanisms 310 can be added in corresponding other horizontal directions.

[0048] As Figure 6 shown, in the embodiment of the present utility model, both the first horizontal driving mechanism and the second horizontal driving mechanism include a driving motor 321 and a lead screw pair 322. The driving motor 321 is arranged on the frame 200 and is in transmission connection with the screw rod of the lead screw pair 322. The screw rod is formed with two screw threads with opposite thread directions. A nut in threaded fit is arranged on each screw thread section, and the nut is connected to the corresponding film clamping mechanism 310. Then, one driving motor 321 can drive two opposite film clamping mechanisms 310 to move simultaneously, and the moving distances of the two film clamping mechanisms 310 are the same, ensuring the uniformity of the tension on both sides of the adhesive film 500.

[0049] Of course, the present utility model is not limited thereto. Multiple driving motors 321 and lead screw pairs 322 can also be set. Each driving motor 321 drives one film clamping mechanism 310 correspondingly, or among the two relatively arranged film clamping mechanisms 310, one film clamping mechanism 310 is driven by the driving motor 321, and the other film clamping mechanism 310 keeps its position fixed. The driving member of the horizontal driving mechanism is not limited to the driving motor 321, and a cylinder can also be used.

[0050] Please refer to Figure 7 as well. In the embodiment of the present utility model, the film clamping mechanism 310 includes a lower clamping block 311, a flipping seat 312 and an upper clamping block 313. The lower clamping block 311 is connected to the driving end of the tensioning driving assembly 320. The fixed end of the flipping seat 312 is arranged on the lower clamping block 311, and the movable end of the flipping seat 312 is connected to the upper clamping block 313. Among them, both the lower clamping block 311 and the upper clamping block 313 extend along a direction parallel to the groove 130. The edge of the adhesive film 500 is clamped between the lower clamping block 311 and the upper clamping block 313. During the tensioning process, the edge of the adhesive film 500 is stressed as a whole, which can avoid the situation of film clamping deformation caused by excessive local tension.

[0051] Please refer to Figure 7 as well. In the embodiment of the present utility model, an auxiliary sliding rail 230 is further arranged on the frame 200. The auxiliary sliding rail 230 is arranged along the moving direction of the film clamping mechanism 310. A slider is arranged on the auxiliary sliding rail 230, and the slider is connected to the lower clamping block 311. The stability of the movement of the film clamping mechanism 310 can be further improved through the auxiliary sliding rail 230.

[0052] Furthermore, the frame 200 includes an upper mounting plate 210 and a lower mounting plate 220 that are spaced apart in the height direction. A first sliding rail 323 and a second sliding rail 324 that extend along the first horizontal direction and the second horizontal direction respectively are arranged on the lower mounting plate 220. A driving motor 321 is arranged on one side of the sliding rail, and a bearing seat for the screw rod to pass through is arranged on the other side of the sliding rail. The upper mounting plate 210 is used to place the transfer platform 100, and the mounting height of the upper mounting plate 210 satisfies that after the transfer platform 100 is placed on the upper mounting plate 210, the upper surface of the frame body 110 is flush with the upper surface of the lower clamping block 311.
