A cover plate 12 is provided at the end, and a transmission plate 13 is provided at the bottom end of the slider 10, the cover plate 12 extends to the top of the injection molding positioning groove 8, the transmission plate 13 penetrates the side of the injection molding positioning plate 7, the transmission plates 13 of the two sliders 10 correspond to the vertical slide grooves 4 of the two side plates 2 one by one, the transmission plates 13 extend into the corresponding vertical slide grooves 4 and are provided with a transmission block 14, the top of the transmission block 14 is provided with a driven inclined surface 15, and the top wall of the vertical slide groove 4 is provided with a driving inclined surface 16 for matching with the driven inclined surface 15; The lifting mechanism comprises a lifting plate 17 disposed above the injection molded part positioning plate 7 , and the lifting plate 17 is fixedly connected to the injection molded part positioning plate 7 via a connecting column 18 .

[0018] By adopting the above scheme, the working process of the injection molding film laminating device of the present invention is as follows: When the lifting plate 17 drives the injection molding positioning plate 7 upward, the injection molding positioning plate 7 will drive the transmission plate 13 and the transmission block 14 upward together. When the transmission block 14 moves upward until the driven inclined surface 15 on it contacts the driving inclined surface 16 of the vertical slide 4, the driving inclined surface 16 and the driven inclined surface 15 will be contacted and matched to make the transmission block 14 move outward a certain distance. At the same time, the transmission block 14 will drive the slider 10 to slide through the transmission plate 13 and compress the horizontal spring 11, so that the slider 10 drives the cover plate 12 is moved from the top of the injection molding part positioning groove 8 until the injection molding part positioning plate 7 is in place, the injection molding part 100 can be placed in the injection molding part positioning groove 8, and the bottom surface of the injection molding part 100 protrudes from the bottom surface of the injection molding part positioning plate 7, and then the protective film 200 is placed in the protective film positioning groove 6 of the protective film positioning plate 5, thereby completing the loading of the injection molding part 100 and the protective film 200; after completion, the injection molding part positioning plate 7 is driven downward by the lifting plate 17, and the injection molding part positioning plate 7 is moved downward. During the process, the transmission plate 13 and the transmission block 14 will be driven downward together. When the transmission block 14 moves downward, the driven inclined surface 15 on it will gradually separate from the driving inclined surface 16. During this process, the slider 10 will drive the cover plate 12 to move to the top of the injection molding positioning groove 8 under the elastic restoring force of the horizontal spring 11, so that the injection molding 100 is pressed and fixed by the cover plate 12. The staff does not need to perform additional fixing operations on the injection molding 100, which reduces the labor intensity of the staff and improves the production efficiency. After the injection molding 100 is fixed, the lifting plate 17 drives the injection molding positioning plate 7 to continue to move downward until the injection molding positioning plate 7 moves downward into place, and the bottom surface of the injection molding 100 will contact the protective film 200, so that the protective film 200 is attached to the bottom surface of the injection molding 100, thereby completing the film pasting work. After completion, the injection molding positioning plate 7 is driven upward by the lifting plate 17 to move into place, so that the cover plate 12 is removed from the top of the injection molding positioning groove 8, so as to take out the injection molding 100 with the film pasted.

[0019] Furthermore, the injection molding film laminating equipment also includes a bubble removal mechanism, which includes a bubble removal roller 19, a roller frame 20, a horizontal screw rod 21, a vertical rack 22 and a vertical guide rail 23. One end of the roller frame 20 is slidably connected to the bottom of the injection molding positioning plate 7 through a horizontal slide rail 24, and the bubble removal roller 19 is rotatably connected to the other end of the roller frame 20, and the bubble removal roller 19 is located below the injection molding positioning plate 7. The horizontal screw rod 21 is rotatably connected to the bottom of the injection molding positioning plate 7 through a screw rod seat 25, and the horizontal screw rod 21 is threadedly connected to the roller frame 20. The vertical guide rail 23 is provided Placed on the top of the base 1, the vertical guide rail 23 is located on the outside of the frame, and a support block 26 is provided on the side of the vertical guide rail 23, the vertical rack 22 is slidably connected to the vertical guide rail 23, the vertical rack 22 is located above the support block 26, and a vertical spring 27 is connected between the vertical rack 22 and the support block 26, one end of the horizontal screw rod 21 passes through the vertical slide groove 4 of the side plate 2 and is connected to a gear 28 meshing with the vertical rack 22, a stop block 29 is provided on the side of the vertical rack 22, and one end of the transmission plate 13 extends to form a pressure block 30 for contacting the stop block 29. By adopting the above scheme, in the process of the injection molding part 100 being driven downward by the injection molding part positioning plate 7, the horizontal screw rod 21 will drive the gear 28 to move downward along with the injection molding part positioning plate 7. When the horizontal screw rod 21 moves downward, it will rotate forward through the meshing of the gear 28 and the vertical rack 22, so that the horizontal screw rod 21 drives the roller frame 20 to move through the threaded connection with the roller frame 20, and then the roller frame 20 drives the bubble removal roller 19 to move from the lower left side of the injection molding part 100 to the lower right side of the injection molding part 100, so as to avoid the roller frame 20 and the bubble removal roller 19 from interfering with the subsequent film pasting work. When the roller frame 20 and the bubble removal roller 19 move into place, the pressing block 30 will contact the stopper 29. In the process of the injection molding part positioning plate 7 continuing to move downward and performing the film pasting work, the pressing block 30 will press the stopper 29 to move downward together, so that the stopper 29 drives the vertical rack 22 downward and compresses the vertical spring 27. The roller frame 20 and the bubble removal roller 19 remain stationary until the injection molding part positioning plate 7 moves up to a certain distance, and the pressure block 30 is separated from the stop block 29. The injection molding part positioning plate 7 continues to move upward, and the horizontal screw rod 21 rotates in the opposite direction through the meshing of the gear 28 and the vertical rack 22, so that the roller frame 20 drives the bubble removal roller 19 to move from the lower right side of the injection molding part 100 to the lower left side of the injection molding part 100. During this process, the bubble removal roller 19 will contact the protective film 200 adhered to the bottom surface of the injection molding part 100, and squeeze out the bubbles between the injection molding part 100 and the protective film 200 during the rolling process.

[0020] Furthermore, the lifting mechanism further includes a driving cylinder 31, which is disposed on the top of the top plate 3, and a piston rod of the driving cylinder 31 passes through the top plate 3 downward and is fixedly connected to the lifting plate 17. By adopting the above scheme, the driving cylinder 31 drives the lifting plate 17 to move upward and downward.

[0021] Furthermore, a channel 32 for the transmission plate 13 to slide is provided inside the injection molded part positioning plate 7 .

[0022] Furthermore, the transmission plate 13 is slidably connected with the corresponding vertical slide groove 4. By adopting the above solution, the movement of the injection molded part positioning plate 7 can be guided to improve the stability of the injection molded part positioning plate 7 during movement.

[0023] Furthermore, the bubble removal roller 19 is a flexible roller.
