As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a flexible printed circuit board exposure machine capable of feeding materials step by step, which includes an unwinding device 1, an exposure device 2 and a feeding device. The unwinding device 1 is used for unwinding the flexible circuit board substrate 10, so that the flexible circuit board substrate 10 can be continuously fed. The exposure device 2 is used for exposing the flexible circuit board base material 10 of the exposure station. After the unreeling device 1 unreels the flexible circuit board base material 10, the flexible circuit board base material 10 passes through an exposure station and is exposed by the exposure device 2 at the exposure station. Wherein, unwinding device 1 and exposure device 2 both can select the structure among the prior art for use, so need not be repeated here to the structure of both.
The feeding device comprises a first clamping mechanism 4 and a second clamping mechanism 5. First fixture 4 and second fixture 5 both set up in exposure device 2 one side that deviates from unwinding device 1, and first fixture 4 is close to exposure device 2 relative to second fixture 5. After being unreeled by the unreeling device 1, the flexible circuit board substrate 10 sequentially flows through the exposure device 2, the first clamping mechanism 4 and the second clamping mechanism 5.
The first clamping mechanism 4 is movable, and the first clamping mechanism 4 is used for clamping the flexible circuit board substrate 10 at an initial position and moving towards the second clamping mechanism 5 so as to pull an unexposed section of the flexible circuit board substrate 10 into an exposure station. The second clamping mechanism 5 is used for clamping the flexible circuit board substrate 10 when the first clamping mechanism 4 returns to the initial position.
In the above example, the first clamping mechanism 4 may move along a straight line, and after the flexible printed circuit board substrate 10 is exposed by the exposure device 2 at the exposure station, the first clamping mechanism 4 may clamp the flexible printed circuit board substrate 10, move the exposed section of the flexible printed circuit board substrate 10 out of the exposure station, and pull the unexposed section of the flexible printed circuit board substrate 10 into the exposure station. The first clamping mechanism 4 can realize the stepping feeding of the flexible circuit board base material 10, so that the flexible circuit board base material 10 is fed into the exposure station section by section, and the displacement precision is higher.
Here, it should be noted that: as shown in fig. 1 and fig. 2, the exposure machine further includes a winding device 3, the winding device 3 is located on a side of the second clamping mechanism 5 away from the first clamping mechanism 4, and the winding device 3 is used for winding the flexible circuit board substrate 10. The winding device 3 may be a structure in the prior art, and therefore, the structure thereof is not described herein again. After the flexible printed circuit board substrate 10 is exposed at the exposure station, the first clamping mechanism 4 clamps the flexible printed circuit board substrate 10 and moves from the initial position to the direction of the second clamping mechanism 5 to a set position, and the set displacement is equal to the length of the flexible printed circuit board substrate 10 drawn into the exposure station. After the first clamping mechanism 4 clamps the flexible circuit board substrate 10 and moves to the first position, the winding device 3 winds the flexible circuit board substrate 10 pulled by the first clamping mechanism 4; after the rolling device 3 finishes rolling the pulled part of the flexible circuit board base material 10, the second clamping mechanism 5 clamps the flexible circuit board base material 10; then the first clamping mechanism 4 loosens the flexible circuit board base material 10 and returns to the initial position; then, the second clamping mechanism 5 also releases the flexible circuit board substrate 10, i.e. completing the feeding process of the flexible circuit board substrate 10.
The first and second holding mechanisms 4 and 5 may have the same or different structures, as long as they can hold and release the flexible wiring board substrate 10. Hereinafter, a specific example in which the structures of the first clamping mechanism 4 and the second clamping mechanism 5 are the same will be described, and since the structures of the first clamping mechanism 4 and the second clamping mechanism 5 are the same, only the structure of the first clamping mechanism 4 will be described below, and those skilled in the art can deduce the structure of the second clamping mechanism 5 from the description of the first clamping mechanism 4.

The output end of the driving cylinder 42 is connected to the pressure plate 43, and the driving cylinder 42 is used for driving the pressure plate 43 to move, so that the pressure plate 43 is relatively close to or far away from the supporting surface 411. When the driving cylinder 42 drives the platen 43 to approach the supporting surface 411, the flexible printed circuit board substrate 10 can be pressed and fixed on the supporting surface 411, so as to clamp the flexible printed circuit board substrate 10.
As shown in fig. 4, the supporting surface 411 may be provided with a through hole 410, so as to reduce the frictional resistance between the flexible circuit board substrate 10 and the supporting surface 411, and facilitate the advance of the flexible circuit board substrate 10.
In order to improve the clamping effect, it is preferable that the number of the clamping structures is two and the clamping structures are located on both sides of the flexible wiring board substrate 10 in the width direction, as shown in fig. 3 and 4. Specifically, one of the holding structures is located on one side of the flexible wiring board substrate 10 in the width direction, and the other is located on the other side of the flexible wiring board substrate 10 in the width direction.

The aforementioned first clamping mechanism 4 is disposed on the movable block 6 to move by the movable block 6.
Here, it should be noted that: when the first clamping mechanism 4 comprises the supporting block 41 and the clamping structure, the movable block 6 may be fixed relative to the supporting block 41, for example, by a screw connection; or the movable block 6 and the supporting block 41 are integrally formed. The driving cylinder 42 of the clamping structure is disposed on the supporting block 41, so that when the driving cylinder 42 drives the pressing plate 43 to press and fix the flexible circuit board substrate 10 on the supporting block 41, the supporting block 41 can drive the driving cylinder 42 and the pressing plate 43 to move together.
In order to save manpower, it is preferable that the aforementioned exposure machine further includes a driving mechanism for driving the movable block 6 to move. As shown in fig. 3, the driving mechanism may include a linear motion module 7 to move the movable block 6 through the linear motion module 7.

Of course, in order to improve the movement accuracy of the movable block 6, the exposure machine may further include a guide mechanism for guiding the movement of the movable block 6. As shown in fig. 4, the guide mechanism may include a slide groove 81, and the aforementioned movable block 6 is configured to be disposed in the slide groove 81. Preferably, the driving mechanism may include a housing 8, the linear motion module 7 is disposed in the housing 8, the housing 8 has the sliding slot 81, and the movable block 6 passes through the sliding slot 81 and is connected to the output end of the linear motion module 7.
