[0034] As Figure 1 positioned Figure 7As shown, in an embodiment, a laser card film pressing device 1 comprises a base 10 and an upper die assembly 20, the base 10 is provided with a lower die plate 11, the upper die assembly 20 comprises a clamping plate 21, an upper die plate 22, a plurality of supporting blocks 23 and a plurality of push springs 24, the clamping plate 21 is slidingly arranged on the base 10 in the vertical direction, one end of the upper die plate 22 is slidingly arranged on the clamping plate 21 in the horizontal direction, and the other end of the upper die plate 22 extends from the clamping plate 21, the clamping plate 21 is provided with an inclined corner portion 212 at each corner position, each supporting block 23 is slidingly arranged on each inclined corner portion 212, and each push spring 24 is arranged on each supporting block 23, each push spring 24 is used to push each supporting block 23 away from the clamping plate 21, and the end of each supporting block 23 away from the clamping plate 21 abuts against the laser film, when the clamping plate 21 drives each supporting block 23 and the upper die plate 22 to slide downward and close to the lower die plate 11, the upper die plate 22 pushes each supporting block 23 to push the laser film in the peripheral direction, so that the laser film is evenly covered on the card paper.

[0035] It should be noted that the base 10 comprises a bottom plate 12 and a plurality of stand columns 13, the bottom plate 12 is provided with a bottom die groove, the bottom die groove is provided with a plurality of positioning columns, the lower die plate 11 is provided with a plurality of positioning holes, each positioning hole is inserted into each positioning column one by one, so that the lower die plate 11 can be completely embedded into the bottom die groove. Further, each stand column 13 is arranged at each corner position of the bottom plate 12, further, each corner position of the clamping plate 21 is respectively arranged on each stand column 13, so that the clamping plate 21 can slide up and down relative to the base 10. The clamping plate 21 is provided with a film placing groove 211, the film placing groove 211 is provided with a sliding groove on each of the two inner side walls in the horizontal direction and facing each other, and the upper die plate 22 is provided with a clamping strip on each of the two ends of the side surface facing each other, the two clamping strips are slidingly arranged in the two sliding grooves, so that the upper die plate 22 can slide on the clamping plate 21 in the horizontal direction relative to the clamping plate 21, and the side surface of the upper die plate 22 away from the two clamping strips extends from the film placing groove 211. It should be noted that the two sliding grooves are arranged close to the slot of the film placing groove 211, so that when the upper die plate 22 slides on the clamping plate 21, there is still a gap between the upper die plate 22 and the inner bottom wall of the film placing groove 211.

[0036] It should be noted that the four corners of the clamping plate 21 are provided with inclined angle portions 212, and each inclined angle portion 212 is located at one side of the slot of the film placing groove 211, each inclined angle portion 212 tends to be a right triangle structure, and the right angle surface of each inclined angle portion 212 extends along the direction of the slot of the film placing groove 211, so that each inclined angle portion 212 abuts against the upper die plate 22 extending from the clamping plate 21. It should be noted that the distance of each inclined angle portion 212 extending from the slot of the film placing groove 211 is less than the distance of the upper die plate 22 extending from the slot of the film placing groove 211. Further, the inclined surface of each inclined angle portion 212 is provided with a T-shaped rail, and each support block 23 is provided with a T-shaped groove, each T-shaped groove is correspondingly connected with each T-shaped rail, so that each support block 23 can slide on each inclined angle portion 212, and the sliding direction of each support block 23 and the sliding direction of the clamping plate 21 have an included angle. Further, since each inclined angle portion 212 is arranged on the clamping plate 21, and the distance of each inclined angle portion 212 extending from the slot is less than the distance of the upper die plate 22 extending from the slot, when each support block 23 slides away from the clamping plate 21, the side surface of each support block 23 adjacent to the T-shaped groove slides along the inclined direction to abut against the upper die plate 22, so that the upper die plate 22 pushes each support block 23, avoiding each support block 23 from sliding off each inclined angle portion 212. Further, the height of each support block 23 is consistent with the distance of the upper die plate 22 extending from the slot, so that when each support block 23 slides to abut against the clamping plate 21, the end of each support block 23 away from the clamping plate 21 and the end of the upper die plate 22 away from the clamping plate 21 are in the same horizontal plane, and when each support block 23 slides to abut against the upper die plate 22, the end of each support block 23 away from the clamping plate 21 extends outward relative to the upper die plate 22. Thus, under the influence of gravity, when the clamping plate 21 drives each support block 23, each inclined angle portion 212 and the upper die plate 22 to slide downward, each support block 23 first abuts against the laser film, and then each inclined angle portion 212 on the clamping plate 21 extrudes each support block 23 along the T-shaped groove, so that each support block 23 moves along the horizontal direction to the four corners of the laser film, thereby straightening the wrinkles of the laser film. When each inclined angle portion 212 extrudes each support block 23 to make the end of each support block 23 away from the laser film abut against the clamping plate 21, the end of each support block 23 close to the laser film keeps horizontal with the end of the upper die plate 22 away from the clamping plate 21, thereby the upper die plate 22 can continuously keep the laser film flat when pressing the laser film, so as to improve the production quality of the card film pressing.

[0037] It should be noted that each push spring 24 is arranged on each support block 23, and each push spring 24 pushes each support block 23 and the clamping plate 21, so that the end of each support block 23 away from the clamping plate 21 extends outward more than the end of the upper die plate 22 away from the clamping plate 21, thereby each support block 23 can abut against the laser film earlier than the upper die plate 22.

[0038] As Figures 1 to 4As shown in FIG. 1, the upper die assembly 20 further comprises a plurality of anti-skid rubber pads 25, each of which is arranged on the end of each support block 23 away from the clamping plate 21.

[0039] It should be noted that each anti-skid rubber pad 25 is arranged on the end of each support block 23 away from the clamping plate 21 in one-to-one correspondence, and each anti-skid rubber pad 25 is used to abut against the laser film to increase the friction between each support block 23 and the laser film, while reducing the pressure injury or scratch caused by each support block 23 to the laser film.

[0040] As shown in FIG. 1, the upper die assembly 20 further comprises a plurality of anti-skid rubber pads 25, each of which is arranged on the end of each support block 23 away from the clamping plate 21. Figure 1 , Figures 3 to 4 As shown in FIG. 1, the upper die assembly 20 further comprises a plurality of anti-skid rubber pads 25, each of which is arranged on the end of each support block 23 away from the clamping plate 21.

[0041] It should be noted that the two clamping strips of the upper die plate 22 are respectively provided with pin holes, and the two opposite ends of the clamping plate 21 are respectively provided with pin grooves, and the two pin grooves penetrate the two sliding grooves. When the upper die plate 22 slides on the clamping plate 21 to make the pin grooves communicate with the pin holes, the pin 28 is inserted into the pin hole from the end of the pin hole away from the pin groove, and extends into the pin groove, so that the upper die plate 22 cannot slide horizontally relative to the clamping plate 21. When it is necessary to replace the upper die plate 22, only the two pins 28 need to be pulled out of the pin grooves and the pin holes, so that the upper die plate 22 can slide horizontally relative to the clamping plate 21, thereby enabling the upper die plate 22 to slide out of the clamping plate 21. In this way, the laser card film pressing device 1 of the present application can quickly disassemble and replace the upper die plate 22, thereby improving the production efficiency.

[0042] As shown in FIG. 1, the upper die assembly 20 further comprises a plurality of anti-skid rubber pads 25, each of which is arranged on the end of each support block 23 away from the clamping plate 21. Figures 1 to 2 As shown in FIG. 1, the upper die assembly 20 further comprises a plurality of anti-skid rubber pads 25, each of which is arranged on the end of each support block 23 away from the clamping plate 21.

[0043] It should be noted that the base 10 further comprises a top plate 14, the ends of each column 13 away from the bottom plate 12 are connected with the top plate 14, the clamping plate 21 and the pressure piece 26 are slidably arranged on each column 13, the clamping plate 21 is slidably arranged on one side of each column 13 close to the bottom plate 12, the pressure piece 26 is slidably arranged on one side of each column 13 close to the top plate 14, and the clamping plate 21 and the pressure piece 26 can slide up and down relative to each column 13. Further, the pressure piece 26 comprises a pressing plate 261, a push plate 262 and a plurality of slide columns 263, the pressing plate 261 is slidably arranged in the film placing groove 211, and the pressing plate 261 is located in the gap between the upper mold plate 22 and the clamping plate 21. Each slide column 263 is arranged on the end of the clamping plate 21 away from the upper mold plate 22, and one end of each slide column 263 is connected with the pressing plate 261, and the other end of each slide column 263 is connected with the push plate 262, and the four corners of the push plate 262 are respectively connected with each column 13 in a sliding manner, so that the push plate 262 can slide up and down relative to each column 13, thereby driving the pressing plate 261 to slide up and down relative to the film placing groove 211. Further, the hydraulic piece 27 is a hydraulic cylinder structure, the hydraulic piece 27 is arranged on the side of the top plate 14 away from each column 13, and the output shaft of the hydraulic piece 27 is connected with the side of the push plate 262 away from each slide column 263 through the top plate 14, so that the hydraulic piece 27 drives the pressing plate 261 to slide up and down relative to the clamping plate 21 in the film placing groove 211 through the push plate 262, thereby enabling the pressing plate 261 to push the upper mold plate 22 and the lower mold plate 11 to tightly press the laser film and the card paper, so that the laser pattern or texture on the laser film is transferred to the surface of the card paper.

[0044] As shown in Figures 1 to 2 , in an embodiment, the pressure piece 26 further comprises a buffer rubber pad 264, the buffer rubber pad 264 is arranged on the pressing plate 261, and the buffer rubber pad 264 is located between the pressing plate 261 and the upper mold plate 22.

[0045] It should be noted that the buffer rubber pad 264 is arranged on the side of the pressing plate 261 facing the upper mold plate 22, so that when the pressing plate 261 pushes the upper mold plate 22, the problem of uneven stress caused by deformation and wear of the pressing plate 261 and the upper mold plate 22 due to long-time loosening and pushing is avoided, thereby improving the service life of the laser card film pressing device 1 of the present application, and improving the film pressing effect and production efficiency.

[0046] As shown in Figures 1 to 2 , in an embodiment, the pressure piece 26 further comprises a plurality of reset springs 265, each reset spring 265 is sleeved on each slide column 263, and each reset spring 265 is located between the clamping plate 21 and the pressing plate 261.

[0047] It should be noted that each reset spring 265 is located between the clamping plate 21 and the pressing plate 261, each reset spring 265 is used to push the clamping plate 21 away from the pressing plate 261, so that the clamping plate 21 drives the upper die plate 22 to quickly move away from the lower die plate 11. Further, when each reset spring 265 simultaneously pushes the clamping plate 21 to slide upward, the clamping plate 21 will simultaneously drive the upper die plate 22 to move away from the lower die plate 11, at the same time, each push spring 24 will push each support block 23 to abut against the position around the laser film after the film pressing is completed, so that the upper die plate 22 can smoothly move away from the laser film, avoiding the case that the upper die plate 22 is brought up due to that the laser film is overheated and softened after being pressed for too long time, and is adhered to the upper die plate 22.

[0048] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
