[0045] The foam roll drum is arranged on the top of the frame 1, the foam roll drum 4 is used to wind and roll the conductive foam material tape, the rotating disc 5 is arranged in the middle of the frame 1, and the rotating disc 5 is used to pull and wind the conductive foam material tape on the foam roll drum onto the rotating disc 5; the cutting mechanism 6 is arranged on the frame 1 at the side end of the rotating disc 5, so as to cut the conductive foam material tape on the rotating disc 5 into sheets, and the attaching mechanism 7 is arranged on the frame 1 above the lifting and supporting assembly 3, It is used to absorb and mount the sheet-shaped conductive foam from the rotating disc 5 on the flexible circuit board; the rotating disc 5 can smoothly transfer the rolled conductive foam tape from the foam reel 4 to the rotating disc 5, preparing for the subsequent foam pasting processing steps, the cutting mechanism 6 can cut the conductive foam tape transferred to the rotating disc 5 into the required length, and the attaching mechanism 7 can accurately attach the cut sheet-shaped conductive foam sheet to a specific position of the flexible circuit board to ensure good contact between the conductive foam and the flexible circuit board.

An avoidance groove 10 is provided on the frame 1, and the avoidance groove 10 is used for allowing the clamping arm 83 to move close to or away from the flexible circuit board along the Y-axis direction. After the conductive foam is mounted on the flexible circuit board, the lifting support component 3 is moved away from the bottom of the flexible circuit board, thereby reserving space for the bending process of the flexible circuit board. When the flexible circuit board needs to be bent, the biaxial moving component 81 can drive the clamping arm 83 to approach the flexible circuit board. At this time, the flexible circuit board is clamped between the two clamping arms 83. Then the finger cylinder 82 is actuated to prompt the clamping arm 83 to clamp the flexible circuit board.

The setting of the cutting groove 510 can facilitate the cutting mechanism 6 to cut the conductive foam in the cutting groove 510; it should be noted that the length of the gap 52 determines the length of the conductive foam to be cut.

[0049] like Figures 2 to 3 As shown, further, the cutting mechanism 6 includes a Y-axis cylinder 61, a first slide rail 62, a first slider 63, a movable clamp seat 64 and a cutting knife 65.

When it is necessary to attach the conductive foam, the Z-axis cylinder 71 can drive the lifting frame 74 to perform a lifting action, so that the lifting frame 74 moves to the top of the cut sheet of conductive foam, and then the adsorption arm 73 can generate negative pressure to adsorb the conductive foam. Then, the Z-axis cylinder 71 continues to control the lifting frame 74 to descend, so that the conductive foam can be accurately attached to the flexible circuit board.

The pushing cylinder 95 is arranged on the back of the frame 1, and its movable end is arranged toward the swing arm 93. The pushing cylinder 95 is used to adjust the pressure of the pressure roller 92 on the rotating disc 5.

Through the lifting action of the lifting cylinder 31, the supporting block 33 can be raised to the bottom of the flexible circuit board to ensure that the conductive foam is in close contact with the flexible circuit board during the attachment process, avoid the flexible circuit board from being suspended, and maintain a certain pressure on the flexible circuit board, thereby improving the attachment effect of the conductive foam.

[0054] like Figure 3 As shown, further, a rotating motor 52 is provided on the frame 1 at the back of the rotating disc 5, and the rotating motor 52 is connected to the rotating disc 5 to drive the rotating disc 5 to rotate, so that the conductive foam material strip on the foam roll 4 can be transferred and wound on the rotating disc 5.
