Specific embodiment
In order to more fully understand technology contents of the invention, combined with specific embodiments below to technical solution of the present invention into
One step introduction and explanation, but not limited to this.
The specific embodiment as shown in Fig. 2 to 3, a kind of removal rigid-flex combined board flexible board area burr provided in this embodiment
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 outer dimension precision is high and at low cost, does not waste material.
As shown in figure 3, a kind of processing method for removing rigid-flex combined board flexible board area burr, this method comprises:
S1, certain size is extended out to garbage area along two side of soft board of the non-link bit in flexible region, using molding gong knife feed；
S2, after taking off lid, flared portions are removed using laser cutting along the trim line of the soft board of the non-link bit in flexible region.
As shown in Fig. 2, the dotted line in figure is the feed line for forming gong knife, that is, form the cutting line of gong knife；Solid line is laser
The cutting line of cutting.
It is first using molding gong knife feed, to the soft board two sides along the non-link bit in flexible region for above-mentioned S1 step
Certain size is extended out to garbage area to be cut, thicker waste material can be quickly cut, while being the laser of subsequent S2 step
Cutting is prepared.
Above-mentioned S2 step, after taking off lid, along the trim line of the soft board of the non-link bit in flexible region, using laser cutting, removal
The step of flared portions, first must carry out waste material to take off lid processing here, guarantee that thickness when cutting is that laser cutting permits
Perhaps in the range of depth of cut, the incomplete phenomenon of cutting is avoided the occurrence of, using laser along the soft of the non-link bit in flexible region
The shape wire cutting of plate, can keep the prototype of the outer dimension of soft board, so that the dimensional accuracy of soft board shape is high.
After the completion of forming the feed of gong knife, then along the soft board shape 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, and without repairing by hand, and soft board outer dimension precision is high.
For above-mentioned S2 step, two side of soft board along the non-link bit in flexible region extends out certain size to garbage area, uses
The step of forming the feed of gong knife, comprising the following specific steps
In the position of rigid-flexible combination, gong knife is formed along the trim line of the soft board of the non-link bit in flexible region, is stretched in vertical direction
Enter the soft board region feed 0.4mm to 0.6mm of the non-link bit in flexible region；
Molding gong knife, which turns round, extends out feed to garbage area along two side of soft board of the non-link bit in flexible region.
Specifically, the soft board region feed 0.4mm to 0.6mm that the non-link bit in flexible region is protruded into vertical direction, be in order to
Convenient for forming the feed of gong knife and convenient for keeping the smooth of appearance.
In the step of molding gong knife turn extends out feed to garbage area along two side of soft board of the non-link bit in flexible region, specifically
0.3mm is extended out to 0.5mm feed to garbage area along two side of soft board of the non-link bit in flexible region, is for the ease of post laser herein
Flash removed is removed in cutting.
Preferably, 0.4mm feed is extended out to garbage area along two side of soft board of the non-link bit in flexible region after molding gong knife turns round.
Certainly, in other embodiments, above-mentioned molding gong knife turn round after along two side of soft board of the non-link bit in flexible region to useless
Material area extends out 0.3mm to any value feed between 0.5mm.
Preferably, the above-mentioned position in rigid-flexible combination, molding gong knife along the soft board of the non-link bit in flexible region trim line,
In the step of vertical direction protrudes into the soft board region feed 0.4mm to 0.6mm of the non-link bit in flexible region, specifically in vertical direction
Protrude into the soft board region feed 0.5mm of the non-link bit in flexible region, in order to convenient for feed and keep the smooth of appearance.
Certainly, in other embodiments, the above-mentioned soft board region feed that the non-link bit in flexible region is protruded into vertical direction
Length may be 0.4mm to any value between 0.6mm.
For above-mentioned S2 step, 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 cutting line beginning of the laser cutting is equipped with overhead kick angle.Setting overhead kick angle makes garbage area
The case where being completely disengaged with soft board, avoiding the occurrence of marginal portion bonding.
Further, the cutting line beginning of laser cutting is arranged in arc shaped, and arc length is 0.8mm to 1mm.It in this way can be with
Convenient for the feed of laser cutting, also for the ending convenient for laser cutting.
Specifically, the cutting line beginning of laser cutting is overlapped 0.2mm to 0.4mm with the cutting line of molding gong knife.Here have
Body close to hardboard region part, the cutting line of laser cutting is overlapped with the cutting line that forms gong knife, be herein in order to
The phenomenon that keeping the round and smooth, smooth of soft board edge, the cutting for being cut by laser and forming gong knife avoided to be layered.
Preferably, the cutting line beginning of laser cutting is overlapped 0.3mm with the cutting line of molding gong knife, certainly, in other realities
It applies in example, the length that the cutting line beginning of laser cutting is overlapped with the cutting line of molding gong knife may be 0.2mm to 0.4mm's
Any value.
Further, the length at the overhead kick angle at the cutting line beginning of laser cutting is 0.8mm to 1.2mm.
Preferably, the length at the overhead kick angle at the cutting line beginning of above-mentioned laser cutting is 1.0mm；Certainly, in other realities
Example is applied, the length at the overhead kick angle at the cutting line beginning of above-mentioned laser cutting can be 0.8mm to any number between 1.2mm
Value.
In addition, the starting point at the overhead kick angle at the cutting line beginning of above-mentioned laser cutting is apart from the hardboard region 0.1mm
To 0.3mm, in this way, avoid generating hardboard region laser cutting and caused by damage, the heat being also prevented from around laser cutting
Amount leads to the damage in hardboard region.
Preferably, the starting point at the overhead kick angle at the cutting line beginning of laser cutting is apart from the hardboard region 0.2mm.
Certainly, in other embodiments, the starting point at the overhead kick angle at the cutting line beginning of above-mentioned laser cutting is described in
Hardboard region can be 0.1mm to any value between 0.3mm.
The feed of above-mentioned laser cutting and molding 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 molding gong knife along flexibility
After two side of soft board of the non-link bit in area extends out certain size progress feed cutting to garbage area, carry out taking off lid processing, 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
It cuts off together, without repairing by hand, keeps the high-precision of the outer dimension of soft board, solve asking for flexible region soft board Side burrL
Topic, achievees the effect that at low cost and does not waste material.
It is above-mentioned that technology contents of the invention are only further illustrated with embodiment, in order to which reader is easier to understand, but not
It represents embodiments of the present invention and is only limitted to this, any technology done according to the present invention extends or recreation, by of the invention
Protection.Protection scope of the present invention is subject to claims.
