Specific embodiment
In order to more fully understand the technology contents of the present invention, technical scheme is entered with reference to specific embodiment
One step introduction and explanation, but it is not limited to this.
Specific embodiment as shown in Fig. 2 to 3, a kind of removal rigid-flex combined board flexible board area burr that the present embodiment is provided
Processing method, can be used in the manufacturing process of rigid-flex combined board, and realization solves the problems, such as flexible region soft board Side burrL, soft
Plate appearance and size high precision and low cost, not waste of materials.
As shown in figure 3, a kind of processing method for removing rigid-flex combined board flexible board area burr, the method includes：
S1, the lateral garbage area of soft board two along the non-link bit in flexible region extend out certain size, using shaping gong knife feed；
S2, take off after lid, along the trim line of the soft board of the non-link bit in flexible region, using laser cutting, remove flared portions.
As shown in Fig. 2 the dotted line in figure is the feed line for being molded gong knife, that is, it is molded the line of cut of gong knife；Solid line is laser
The line of cut of cutting.
It is first using shaping gong knife feed, to along the soft board both sides of the non-link bit in flexible region for above-mentioned S1 steps
Certain size is extended out to garbage area to be cut, can quickly cut thicker waste material, while for the laser of follow-up S2 steps
Cutting is prepared.
Above-mentioned S2 steps, after taking off lid, along the trim line of the soft board of the non-link bit in flexible region, using laser cutting, remove
The step of flared portions, waste material must be carried out first taking off lid process here, it is ensured that thickness during cutting is that laser cutting permits
Perhaps in the range of depth of cut, it is to avoid the incomplete phenomenon of cutting occur, using laser along the soft of the non-link bit in flexible region
The profile wire cutting of plate, can keep the prototype of the appearance and size of soft board so that the dimensional accuracy of soft board profile is high.
After the completion of shaping gong knife feed, then along the soft board profile of the non-link bit in flexible region by the way of laser cutting
Line is cut, and soft board burrs on edges is also cut out, without the need for manual repairing, and soft board appearance and size high precision.
For above-mentioned S2 steps, the lateral garbage area of soft board two along the non-link bit in flexible region extends out certain size, adopts
The step of shaping gong knife feed, including step in detail below：
In the position of rigid-flexible combination, shaping gong knife is stretched along the trim line of the soft board of the non-link bit in flexible region in vertical direction
Enter the soft board region feed 0.4mm to 0.6mm of the non-link bit in flexible region；
The lateral garbage area of soft board two that shaping gong knife turns round along the non-link bit in flexible region extends out feed.
Specifically, the soft board region feed 0.4mm to 0.6mm of the non-link bit in flexible region is stretched in vertical direction, be in order to
It is easy to be molded the feed of gong knife and is easy to keep the smooth of outward appearance.
Shaping gong knife turn round along the lateral garbage area of soft board two of the non-link bit in flexible region extend out feed the step of in, specifically
The lateral garbage area of soft board two along the non-link bit in flexible region extends out 0.3mm to 0.5mm feeds, is herein for the ease of post laser
Flash removed is removed in cutting.
Preferably, it is molded the lateral garbage area of soft board two after gong knife turns round along the non-link bit in flexible region and extends out 0.4mm feeds.
Certainly, in other embodiment, above-mentioned shaping gong knife is laterally useless along the soft board two of the non-link bit in flexible region after turning round
Material area extends out any value feed between 0.3mm to 0.5mm.
Preferably, the above-mentioned position in rigid-flexible combination, is molded trim line of the gong knife along the soft board of the non-link bit in flexible region,
The step of vertical direction stretches into the soft board region feed 0.4mm to 0.6mm of the non-link bit in flexible region, specifically in vertical direction
Stretch into the soft board region feed 0.5mm of the non-link bit in flexible region, in order to be easy to feed and keep the smooth of outward appearance.
Certainly, in other embodiment, above-mentioned stretches into the soft board region feed of the non-link bit in flexible region in vertical direction
Length can also be any value between 0.4mm to 0.6mm.
For above-mentioned S2 steps, after taking off lid, along the trim line of the soft board of the non-link bit in flexible region, using laser cutting,
In the step of removing flared portions, the line of cut top of the laser cutting is provided with overhead kick angle.Overhead kick angle is set and causes garbage area
Completely disengage from soft board, it is to avoid the situation of marginal portion bonding occur.
Further, the line of cut top of laser cutting arranges that arc length is 0.8mm to 1mm in arc shaped.So can be with
It is easy to the feed of laser cutting, also for the ending for being easy to laser cutting.
Specifically, the line of cut top of laser cutting overlaps 0.2mm to 0.4mm with the line of cut of shaping gong knife.Here have
That the line of cut of laser cutting overlaps with the line of cut for being molded gong knife near hardboard region part body, be herein in order to
Keep the round and smooth, smooth of soft board edge, it is to avoid the phenomenon of layering occurs in the cutting of laser cutting and shaping gong knife.
Preferably, the line of cut top of laser cutting overlaps 0.3mm with the line of cut of shaping gong knife, certainly, in other realities
In applying example, the length that the line of cut top of laser cutting overlaps with the line of cut of shaping gong knife can also be 0.2mm's to 0.4mm
Any value.
Further, the length at the overhead kick angle at the line of cut top of laser cutting is 0.8mm to 1.2mm.
Preferably, the length at the overhead kick angle at the line of cut top of above-mentioned laser cutting is 1.0mm；Certainly, in other realities
Apply example, the length at the overhead kick angle at the line of cut top of above-mentioned laser cutting can be the arbitrary number between 0.8mm to 1.2mm
Value.
In addition, the starting point at the overhead kick angle at the line of cut top of above-mentioned laser cutting is apart from the hardboard region 0.1mm
To 0.3mm, so, it is to avoid the damage for laser cutting being produced to hardboard region and being caused, the heat being also prevented from around laser cutting
Amount causes the damage in hardboard region.
Preferably, the starting point at the overhead kick angle at the line of cut top of laser cutting is apart from the hardboard region 0.2mm.
Certainly, in other embodiment, the starting point at the overhead kick angle at the line of cut top of above-mentioned laser cutting is apart from described
Hardboard region can be any value between 0.1mm to 0.3mm.
The feed of above-mentioned laser cutting and shaping gong knife is all perpendicular to the longitudinal direction cutting of steel flex combined board.
The method of above-mentioned a kind of solution rigid-flex combined board soft board deburring, by advance using shaping gong knife along flexibility
The lateral garbage area of soft board two of the non-link bit in area extends out certain size to be carried out after feed cutting, carries out taking off lid process, then using sharp
The mode of light cutting removes flared portions, while the burrs on edges of soft board along the trim line of the soft board of the non-link bit in flexible region
Cut off in the lump, without the need for manual repairing, keep the high accuracy of the appearance and size of soft board, solve asking for flexible region soft board Side burrL
Topic, reaches the effect of low cost and non-waste of materials.
The above-mentioned technology contents that the present invention is only further illustrated with embodiment, are easier to understand in order to reader, but not
Represent embodiments of the present invention and be only limitted to this, any technology done according to the present invention extends or recreates, by the present invention's
