[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] This utility model provides an automatic circuit board laminating machine, including a laminating box. A top plate is snapped onto the top of the laminating box.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 4 An automatic circuit board laminating machine includes a laminating box 1, a top plate 2 attached to the top of the laminating box 1, a ventilation groove in the middle of the top surface of the top plate 2, a fixing frame 3 fixedly installed at the edge of the ventilation groove, square grooves in both sides of the inner side wall of the fixing frame 3, heating wires 4 installed inside the square grooves, a card plate 5 on the top of the fixing frame 3, fans 6 embedded in both sides of the top surface of the card plate 5, and a temperature controller 12 in the middle of the front side of the fixing frame 3, with anti-slip stripes on the outer surface of the temperature controller 12.

[0028] When staff apply film to circuit boards, they can place the circuit board to be filmed on top of the clip plate 82. Then, the staff can turn on the power to the heating wire 4 and the fan 6, so that the heating wire 4 starts to dissipate heat. The fan then carries the heat to the surface of the circuit board, cleaning up foreign objects and dust. After that, the staff can turn on the power to the robotic arm 7, so that the robotic arm 7 can perform the film application operation on the surface of the circuit board. After the film application is completed, the staff can turn on the power to the electric slider 81 again, so that the electric slider 81 slides along the sliding groove to the outside of the film application box 1, opening the baffle 9, thus making it convenient for staff to pick up the circuit board.

[0029] Reference Figures 1 to 4 A connecting block 15 is fixedly connected to one side of the inner wall of the film application box 1, and a robotic arm 7 is provided in the middle of the surface of the connecting block 15.

[0030] By connecting block 15 and robotic arm 7, when personnel are applying film to the circuit board, they can turn on the power to robotic arm 7, so that robotic arm 7 can perform film application on the surface of the circuit board.

[0031] Reference Figures 1 to 4 A battery 13 is located on the other side of the front of the film application box 1, and an indicator light 14 is located on the front of the battery 13.

[0032] With the battery 13 and indicator light 14 in place, the indicator light 14 can emit light after the circuit board film is applied, thus making it easier for personnel to pick up the circuit board.

[0033] Reference Figures 1 to 4 The film application box 1 has sliding grooves on both sides of the bottom wall. A moving component 8 is slidably connected inside the sliding groove. The moving component 8 includes an electric slider 81 that is slidably connected to the inner wall of the sliding groove. A snap-fit ​​plate 82 is fixedly connected to the top of the electric slider 81. A circular groove is opened at each of the four corners of the top surface of the snap-fit ​​plate 82. A flexible ball 83 is set inside the circular groove.

[0034] With the installation of the movable component 8 and the film-applying box 1, when personnel need to remove the circuit board, the power supply of the electric slider 81 can be turned on, so that the electric slider 81 drives the snap-fit ​​plate 82 to slide to one side of the through groove, thereby facilitating the removal of the circuit board by personnel to complete the film application.

[0035] Reference Figures 1 to 4 A through groove is provided on one side of the front of the film application box 1. A hinge is threaded to the edge of the through groove. A baffle 9 is hinged to one side of the hinge. An observation window is provided on one side of the film application box 1. A transparent plate 10 is embedded on the surface of the observation window. A handle 11 is provided on one side of the front of the baffle 9.

[0036] The transparent panel 10 and the observation window facilitate personnel to observe the internal function of the film-applying box 1.

[0037] Working principle: When the staff applies film to the circuit board, they can place the circuit board to be filmed on top of the clip plate 82. Then, the staff can turn on the power to the heating wire 4 and the fan 6, so that the heating wire 4 starts to dissipate heat. Then, the fan carries the heat to the surface of the circuit board, thereby cleaning foreign objects and dust from the surface of the circuit board. Then, the staff can turn on the power to the robotic arm 7, so that the robotic arm 7 can perform the film application operation on the surface of the circuit board. After the film application is completed, the staff can turn on the power to the electric slider 81 again, so that the electric slider 81 slides along the sliding groove to the outside of the film application box 1, thereby opening the baffle 9, which facilitates the staff to pick up the circuit board.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
