Description

Technical Field

[0001] This utility model relates to the field of circuit board lamination technology, and in particular to a circuit board lamination device. Background Technology

[0002] A circuit board, usually referring to a printed circuit board, is formed by etching away the unwanted copper foil on a copper-clad board, leaving only the necessary copper foil to form a circuit pattern. Circuit boards can be classified into single-layer boards, double-layer boards, and multi-layer boards according to their structure. When producing multi-layer circuit boards, multiple raw material boards of the same size need to be stacked together, their edges and corners aligned, and then placed on a workbench for heating and pressing.

[0003] A patent document with publication number CN221487986U discloses a circuit board pressing device. In use, a hydraulic cylinder is connected to a hydraulic workstation. An electric heating support plate, an electric heating pressure plate, an upper electromagnet, and a lower electromagnet are all connected to a control device and energized. The circuit board layers are coated with the required adhesive and neatly stacked before being placed on the surface of the electric heating support plate. Both the electric heating support plate and the electric heating pressure plate are energized and heated. Simultaneously, the hydraulic cylinder is controlled to lower the lifting plate and the electric heating pressure plate, pressing the electric heating pressure plate firmly onto the surface of the circuit board. At the same time, the upper and lower electromagnets are energized, causing the lifting plate to be attracted downwards, and the pressure generated by the magnetic force acts on the lifting plate. The pressure is transferred from the four corners to the heating plate, which can evenly distribute the pressure onto the circuit board and ensure sufficient pressure strength, ultimately achieving the purpose of heating and pressing the circuit board. After pressing, the upper and lower electromagnets are de-energized and lose their magnetic attraction. The hydraulic cylinder can be used to lift the lifting plate and the heating plate to remove the pressed circuit board. Although this patent can press the circuit board, the lifting plate and the heating plate are always directly above the base plate, which obstructs the view and makes it inconvenient to place the circuit board. In addition, there is no positioning function for the circuit board. During subsequent pressing, the circuit board is prone to displacement, which will affect the pressing of the circuit board.

[0004] Therefore, it is necessary to provide a circuit board lamination device to solve the above-mentioned technical problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] A circuit board pressing device includes a support frame 4, and further includes: a pressing component 1, a controller 2, a clamping component 3, an electric heating support plate 5, and an electric heating pressure plate 6. The support frame 4 is provided with the pressing component 1 for heating and pressing the circuit board, and the support frame 4 is provided with the clamping component 3 for fixing and positioning the circuit board.

[0029] The pressing assembly 1 includes two lead screw grooves 110. Symmetrical connecting plates 19 are fixedly connected to opposite sides of the two lead screw grooves 110. Corresponding sliders 18 are provided in the two lead screw grooves 110. The support frame 4 is fixedly connected to the two lead screw grooves 110. Corresponding protrusions 17 are fixedly connected to one side of the two sliders 18. One end of the lead screw 11 is movably connected to the inner ends of the two lead screw grooves 110. The two lead screws 11 are threadedly connected to the corresponding sliders 18. One end of the two lead screws 11 passes through one side of the corresponding lead screw groove 110. The output shafts of corresponding motors 15 are fixedly connected to the ends of the two lead screws 110. The two motors 15 are fixedly connected to the corresponding lead screw grooves 110.

[0030] The two ends of the lifting plate 16 are movably connected to one end of the corresponding convex plate 17. The ends of the two ends of the lifting plate 16 are fixedly connected to one end of the corresponding L-shaped rotating rod 14. The shafts of the two L-shaped rotating rods 14 are slidably connected to the corresponding L-shaped sliding groove plates 13. The two L-shaped sliding groove plates 13 are fixedly connected to the corresponding support plates 12. The two support plates 12 are fixedly connected to the corresponding lead screw groove 110.

[0031] The clamping assembly 3 includes a lead screw groove 32, which is fixedly connected to the lower side of the support frame 4. Two sliders 33 are provided within the lead screw groove 32, and each slider 33 is fixedly connected to a corresponding square pressure frame 35. The thickness of the circuit board is greater than the thickness of the corresponding square pressure frame 35. One end of a bidirectional lead screw 34 is movably connected to the inner ends of the lead screw groove 32. The bidirectional lead screw 34 has two sections of threads with opposite directions. The bidirectional lead screw 34 is threadedly connected to the corresponding sliders 33. One end of the bidirectional lead screw 34 passes through one side of the lead screw groove 32, and the end of the bidirectional lead screw 34 is fixedly connected to the center of the turntable 31. The two square pressure frames 35 are slidably connected to corresponding through slots 36, which are respectively located on the support frame 4.

[0032] The upper side of the support frame 4 is fixedly connected to the electric heating plate 5, and the lower side of the lifting plate 16 is fixedly connected to the electric heating pressure plate 6.

[0033] The controller 2 is fixedly connected to one side of the support frame 4.

[0034] The controller 2 is electrically connected to the motor 15, the electric heating support plate 5, and the electric heating pressure plate 6 respectively.

[0035] Working principle: In use, each layer of the circuit board is coated with the required adhesive and neatly stacked before being placed on the surface of the heating support plate 5. The heating support plate 5 and the heating pressure plate 6 are both energized and heated. Then, the turntable 31 is rotated, which drives the bidirectional lead screw 34 to rotate. The bidirectional lead screw 34 drives the corresponding slider 33 to slide. The two sliders 33 drive the square pressure frame 35 to move along the through groove 36. Since the thickness of the circuit board is higher than the thickness of the square pressure frame 35, the two square pressure frames 35 clamp the circuit board to achieve fixed positioning of the circuit board. At this time, the rotation of the turntable 31 is stopped.

[0036] Then, controller 2 starts the two motors 15, which drive the corresponding lead screws 11 to rotate. The two lead screws 11 drive the corresponding sliders 18 to move the convex plates 17 downwards. The two convex plates 17 drive the shafts of the L-shaped rotating rods 14 to move along the inclined groove of the L-shaped slide plate 13. At the same time, the two convex plates 17 drive the lifting plate 16 to swing. When the shaft of the L-shaped rotating rods 14 moves from the inclined groove to the straight groove of the L-shaped slide plate 13, the lifting plate 16 swings. Figure 1 The upright state is changed to a flat state, so that the lifting plate 16 drives the electric heating plate 6 to move down and press it on the surface of the circuit board, so that the electric heating support plate 5 and the electric heating plate 6 finally achieve the purpose of heating and pressing the circuit board.

[0037] Once the circuit board is pressed, the control motor 15 rotates in the opposite direction, causing the shaft of the L-shaped rotating rod 14 to move upward along the straight groove of the L-shaped sliding plate 13. This causes the lifting plate 16 to move the heating plate 6 upward. When the shaft of the L-shaped rotating rod 14 moves along the straight groove of the L-shaped sliding plate 13 to the inclined groove, the lifting plate 16 lifts the heating plate 6, allowing the pressed circuit board to be easily removed.

[0038] Beneficial effects: After applying the required adhesive to each layer of the circuit board and stacking them neatly, they are placed on the surface of the heating support plate 5. The lifting plate 16 can easily pick up and put down the circuit board. The clamping component 3 can fix the circuit board in place. The pressing component 1 can make the lifting plate 16 move the heating plate 6 down and press it on the surface of the circuit board, so that the heating support plate 5 and the heating plate 6 can finally achieve the purpose of heating and pressing the circuit board.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
