Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a flexible circuit board laminating machine. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. In actual processing, circuit boards require coating to protect the circuit board body. In the prior art, the FPC film is automatically pulled downward by the film discharge roller group, and the FPC film is cut by the cutting unit, so that the FPC film cuts around the circuit board are neat and will not be contaminated by debris. The cooperation of the conveying unit and the film discharge roller group can make the circuit board and the FPC film initially pressed and fitted together while conveying the circuit board. The hot pressing roller group can heat the FPC film and further press the FPC film and the circuit board, so that the FPC film and the circuit board are tightly fitted to prevent wrinkles. However, the prior art cannot convey the circuit board as a whole, and the prior art cannot adjust the height of the heating roller according to the thickness of the circuit board and the film. In addition, the prior art cannot quickly replace the film roll, so the prior art has a large room for improvement.

[0003] In order to solve the above problems, a Chinese utility model patent with authorization announcement number CN215735079U discloses a flexible circuit board laminating machine. The device can realize continuous lamination of circuit boards by setting a conveying mechanism, can realize rapid replacement after the film is exhausted by setting a film rolling mechanism, and can provide a stable working environment during lamination by setting a workbench mechanism.

[0004] However, when the device is used, it is not possible to position the circuit board, and it is difficult to ensure that the circuit board is in the middle of the conveying mechanism, which results in the film not being pressed well onto the circuit board, thereby reducing the lamination quality of the circuit board.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: See Figures 1 to 4, a flexible circuit board laminating machine, comprising: a workbench 1, a reeling mechanism 3, a laminating mechanism 5, and a reeling mechanism 4, wherein multiple groups of conveying rollers 11 are rotatably installed at the left position of the workbench 1, and a conveyor belt 12 is installed at the right position of the workbench 1; a positioning mechanism 2 is installed on the workbench 1, and is used to position the circuit board conveyed by the conveying roller; the positioning mechanism 2 includes a positioning slide rail 21 installed on the workbench 1, and positioning slide seats 22 are slidably installed on both the front and rear sides of the positioning slide rail 21, and multiple groups of positioning rollers 23 are rotatably installed on each of the positioning slide seats 22, and a positioning lead screw 25 is also installed on the workbench 1, and the positioning slide seat 22 is threadedly sleeved on the positioning lead screw 25, and a positioning motor 24 is also installed on the front side of the workbench 1, and the output end of the positioning motor 24 is drivingly connected to the shaft end of the positioning lead screw 25. In this embodiment, the thread rotation directions of the front and rear sides of the positioning lead screw 25 are opposite, and the positioning rollers 23 are distributed in the gaps between adjacent conveying rollers 11. In this embodiment, a conveying motor is further provided for driving the conveying roller 11 and the conveying belt to rotate.

[0022] The working principle of the utility model is as follows: when in use, the circuit board to be processed is placed on the conveying roller 11, and then the positioning motor 24 is started, and the positioning motor 24 drives the positioning screw 25 to rotate, so that the positioning slide 22 threadedly mounted on the positioning screw 25 drives the positioning rollers 23 on both sides to approach each other, thereby positioning the circuit board to the middle position, which is convenient for the subsequent lamination work;

[0023] After the positioning of the circuit board is completed, the circuit board is conveyed to the conveyor belt 12 by the conveyor roller 11, and then the unwinding mechanism 3 releases the rolled film tape 13, and the film sheet on the film tape 13 is pressed onto the circuit board by the film pressing mechanism 5. Finally, the released film tape is rolled up by the winding mechanism 4.

[0024] As a further solution, the unwinding mechanism 3 and the rewinding mechanism 4 are both composed of the same winding assembly. The winding assembly includes a winding frame 1 31 fixed to the front side of the upper end of the workbench 1, and a winding frame 2 35 is also slidably installed at the rear side of the upper end of the workbench 1. Winding shaft seats 33 are rotatably installed on the opposite sides of the winding frame 1 31 and the winding frame 2 35, and a winding roller 34 is inserted between the winding shaft seats 33. A winding motor 32 is also installed on the front side of the winding frame 1 31, and the output end of the winding motor 32 is drivingly connected to the shaft end of the winding shaft seat 33.

[0025] The working principle of the winding assembly is: when unwinding, the winding motor 32 drives the winding shaft seat 33 to rotate in the positive direction, thereby driving the winding roller 34 to rotate, so that the wound film tape 13 can be unwound, making it convenient for the film pressing mechanism 5 to press the film on the film tape 13 onto the circuit board;

[0026] When winding, the winding motor 32 drives the winding shaft seat 33 to rotate in the opposite direction, thereby driving the winding roller 34 of the winding mechanism 4 to rotate in the opposite direction, so that the film tape released by the unwinding mechanism 3 can be wound up.

[0027] As a further solution, a push-pull assembly for pushing the winding frame 2 35 to move is also installed on the upper end of the workbench 1, and the push-pull assembly includes a winding seat 36 installed on the upper end of the workbench 1, and a winding electric push rod 37 is installed on the winding seat 36. The telescopic end of the winding electric push rod 37 passes through the winding seat 36 and is fixedly connected to the end of the winding frame 2 35. A winding guide rod is also slidably inserted on the winding seat 36, and the end of the winding guide rod is fixedly connected to the end of the winding frame 2 35.

[0028] When the winding roller 34 needs to be replaced, the winding electric push rod 37 pulls the winding frame 2 35 to move toward the rear side, so that the winding roller 34 is disengaged from the winding shaft seat 33, and then the winding roller 34 is removed, and one end of the new winding roller 34 is inserted into the front winding shaft seat 33, and then the winding electric push rod 37 pushes the winding frame 2 35 to move forward, so that the rear end of the winding roller 34 is also inserted into the winding shaft seat 33, and the replacement work is completed.

[0029] As a further solution, the film pressing mechanism 5 includes a pair of film pressing frames 51 installed at the upper end of the workbench 1, a film pressing roller 53 is rotatably installed in the middle position of the film pressing frame 51, a film pressing motor 52 is also installed on the front side of the film pressing frame 51, the output end of the film pressing motor 52 is drivingly connected to the shaft end of the film pressing roller 53, and guide rollers 54 are rotatably installed on both sides of the film pressing frame 51. In this embodiment, an electric heating rod is inserted into the guide roller 53 on the left side, and the electric heating rod is rotatably connected to the guide roller 53.

[0030] The working principle of the laminating mechanism 5 is: the film on the film belt 13 is heated by the guide roller 53 on the left, and then the laminating motor 52 is started, and the laminating roller 53 is driven to rotate by the laminating motor 52, so that the heated film is pressed onto the circuit board, thereby completing the laminating work.
