Description

Technical Field

[0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical properties, can meet the design needs of smaller and higher density installations, and also help reduce assembly processes and enhance reliability. Flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. They can be bent, wound, and folded freely, and can withstand millions of dynamic bends without damaging the wires. They can be arranged arbitrarily according to spatial layout requirements, and can be moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection. Flexible circuit boards can greatly reduce the size and weight of electronic products, and are suitable for the development of electronic products towards high density, miniaturization, and high reliability.

[0003] At present, some circuits use different styles of flexible circuit boards during the connection process. During the processing of existing circuit boards, the sides of the edges need to be folded.

[0021] Furthermore, a card slot 106 is provided inside the upper end of the fixed plate 102, and a circuit board body 107 is slidably connected to the upper surface of the feeding plate 104. Both ends of the circuit board body 107 are stuck in the two card slots 106, and the circuit board body 107 moves on the feeding plate 104. The card slots 106 on both sides are used to limit the movement direction and position of the circuit board body 107 to avoid position deviation and ensure the smooth progress of subsequent bending operations.

[0022] Furthermore, a through hole 108 is provided inside the fixed plate 102, a rotating rod 109 is rotatably connected inside the through hole 108, rotating plates 110 are fixedly connected at both ends of the rotating rod 109, handles 114 are fixedly connected to the upper ends of the two rotating plates 110, an inner groove 111 is provided inside the rotating plate 110, a slider 112 is slidably connected inside the inner groove 111, a bending rod 113 is fixedly connected between the two sliders 112, and the outer end of the bending rod 113 is slidably connected inside the movable groove 116, After the position of the circuit board body 107 is determined, the staff holds the handle 114 and pulls the rotating plate 110 downward, and uses the bending rod 113 to bend the circuit board body 107. When the bending rod 113 moves, the sliders 112 at both ends move inside the inner groove 111, and the position state is adjusted according to the movement of the position. The circuit board body 107 is double bent at the upper corner and the lower corner at the front end of the feeding plate 104, so that the circuit board body 107 is bent into a curved surface.

[0023] Furthermore, the clamping device 2 also includes a top plate 201, the lower end of the top plate 201 is fixedly connected to two guide rails 202, the lower end of the guide rails 202 is fixedly connected to the upper end of the fixed plate 102, a lifting plate 203 is slidably connected to the guide rails 202, the lower end of the lifting plate 203 is fixedly connected to a protective cotton 204, the upper end of the lifting plate 203 is also provided with a threaded rod 205, the lower end of the threaded rod 205 is rotatably connected to the lower end of the connecting piece fixedly connected to the lifting plate 203, and the outer side of the threaded rod 205 is threadedly connected to the top plate 20 1, the upper end of the threaded rod 205 is fixedly connected with a control disk 206.

While fixing the position, it can also protect the surface of the circuit board body 107 from wear. Then the staff controls the handle 114 to move downward, and uses the bending rod 113 to press the circuit board body 107 to bend it. The bending operation is performed at the two corners at the front end of the feeding plate 104 to achieve the state of bending the circuit board body 107 to a curved surface.
