Description
Technical field
The present invention relates to SMT manufacture fields, in particular to a kind of narrow side FPC die cutting die and clicking technique.
Background technique
Flexible circuit board (FLEXIBLE PRINTED CIRCUIT BOARD abbreviation FPC) is with insulating substrate system flexible
At printed circuit, have the advantages that many rigid printed circuit plates do not have, for example, it can be with free bend, winding, folding
It is folded, any arrangement can be required according to space layout, the volume of electronic product can be substantially reduced using FPC, be applicable in electronic product to
The needs that high density, miniaturization, highly reliable direction are developed.
Requirement with smart phone to screen accounting improves, and to obtain bigger vision area range, accomplishes more narrow frame, and right
The non-display area of backlight constantly compresses, and the overall width of FPC and non-luminescent face width have become narrow frame mobile phone urgent need
The problem captured.
Since the width of FPC is more and more narrow, LED is less than 0.3mm from the most narrow place FPC, weighs LED lamp bead wounded in order to prevent, rushes
Head needs to avoid LED lamp bead, causes hardware cutting die that can not cut, to be unable to complete the outline die of FPC.And it first rushes
The conventional production method for cutting again patch is unable to satisfy increasing quality and efficiency requirements again, therefore how can not weigh wounded
So that product size, quality is all reached design requirement in the case where LED is the difficult point primarily solved.
Fig. 2 is equipped with for narrow side FPC die cutting die schematic diagram in the prior art, including cope plate 1 and lower template 2, cope plate 1
Formed punch 11.Its principle is to be avoided by the way that escape groove 12 is arranged on the formed punch 11 of cope plate 1 to LED lamp bead 4.Due to narrow side
The edge of the 4 distance FPC soft board 3 of LED lamp bead of FPC is less than 0.3mm, and cope plate 1, which avoids LED lamp bead 4, need to reserve 0.2mm, only surplus
The position of lower 0.1mm is for cutting, and hardware cutting die at least needs 0.3mm or more just and can cut, and leads to not complete punching.
Summary of the invention
Narrow side FPC may be implemented the purpose of the present invention is to provide one kind integrally to cut, and cutting precision is high, product quality
Stable narrow side FPC die cutting die and clicking technique.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of narrow side FPC clicking technique, which is characterized in that packet
Include following steps:
A. the FPC soft board for being welded with LED lamp bead is delivered between the cope plate of die cutting die and lower template, and makes LED lamp bead
Towards lower template；
B. FPC soft board is positioned by the positioning column being arranged in lower template；
C. FPC soft board is placed in lower template, LED lamp bead is put into the escape groove of lower template；
D. it drives cope plate to move down by servo motor, the formed punch that cope plate is set and lower template extruding is made to be punched out and add
Work；
E. upper mold sheet reset, punching are completed；
F. lower template carries out de- material to FPC soft board；
G. finished product material is taken out, and finished product material is placed in discharging area.
Further, the step F method particularly includes: moved straight up by the de- material knife being arranged in lower template
Dynamic, the FPC soft board that punching is completed ejects, to complete de- material.
A kind of narrow side FPC die cutting die, the die cutting die include the cope plate being oppositely arranged and lower template, the lower die
Plate is located at the lower section of the cope plate, and the upper surface of the lower template is equipped with punching portion, and the punching portion includes being vertically movable
De- material knife, the escape groove for avoiding LED lamp bead is equipped in the de- material knife, the lower end surface of the cope plate corresponds to punching portion
Position be equipped with and protrude from the formed punch of upper mold plate surface.
Further, the punching portion further includes multiple positioning columns for positioning to FPC soft board, and the positioning column is vertical
The upper surface of lower template is set.
Further, the two sides in the punching portion are equipped with the relief portion for avoiding the LED lamp bead of FPC soft board to be punched.
Compared with prior art, the beneficial effects of the present invention are:
1. making FPC be welded with face-down a, formed punch for cope plate of LED by changing LED escape groove from cope plate to lower template
It does not need to carry out LED empty avoiding when being punched out, therefore cuts space with enough, to realize a type of narrow side FPC
It cuts.
2. normal punching can not be cut before solving and unilateral punching quality is unstable for die cutting die and clicking technique
Calmly, the problem of mold is easily damaged.
3. die cutting die directly exchanges the avoiding hollow groove of original mold, without having to after-processing technology is increased, also it is not necessary to
Change existing production equipment, mass production ability can be realized.
4. the integrated cutting process of narrow frame product may be implemented in die cutting die, product quality and stability are greatly improved,
Narrow frame mobile phone critical problem is solved, to accomplish more narrow frame, to meet customer need.
