Abstract

The utility model discloses a typesetting structure of a non-distance flexible circuit board, which is used for arranging a batch of L-shaped flexible circuit boards on a flexible circuit board. Flexible circuit boards are divided into a plurality of flexible circuit board sets which are distributed on the flexible circuit board in an array mode. The flexible circuit boards in each flexible circuit board set are arranged without distance in a positive L shape and a reverse L shape; the long edges of the flexible circuit boards are adjacent, and the short edges are positioned on both ends of each flexible circuit board set. Thus, each flexible circuit board set is roughly in a rectangle and a tear line is blanked between adjacent flexible circuit boards. Thus, by the non-distance typesetting design for the flexible circuit boards, the utility model eliminates the distance between adjacent flexible circuit boards in the prior art. Thus, the typesetting utilization rate of the flexible circuit boards is raised; the flexible circuit boards are fully used, so the production cost of the flexible circuit boards is dropped and production efficiency is raised.

Description

Continuously apart from the composing structure of flexible PCB

Affiliated technical field

The utility model relates to a kind of composing structure of flexible PCB, relate in particular to a kind of make flexible PCB with continuously apart from the composing structure of arranging, to improve stock utilization.

Background technology

At present, in the electronic product field, flexible PCB (Flexible Printed Circuit is called for short FPC) because of the flexural property of its height and frivolous design feature, is widely used on the electronic product of many pursuit structures miniaturization.

Generally, flexible PCB manufacturer need be produced on a collection of flexible PCB on the one monoblock flexible PCB sheet material when carrying out the batch process of flexible PCB together, afterwards again with the single flexible circuit board one by one stamping-out get off.So how these flexible PCBs arrange, and can influence the utilance and the production efficiency of sheet material, and then influence production cost and enterprise strives power unexpectedly on a monoblock sheet material.If can be under the prerequisite of quality assurance the flexible PCB of arranging of maximal density, then can improve stock utilization, reduce production costs, improve production capacity.

As shown in Figure 5, promptly disclosed a kind of composing structure of flexible PCB.Wherein, shown in flexible PCB be to be applied to the backlight field, roughly be the L type, be arranged on the sheet material tilt certain angle and being arranged in parallel at certain intervals of each row's flexible PCB with upper and lower two alignments row.

Yet, because the overall dimension of this L shaped flexible PCB is less, one side is longer relatively, and generally be to adopt the mode punching out of a stamping-out to form traditionally when the sheet material upper punch cuts out with flexible PCB, so, to stay the spacing of 3.5mm between the adjacent flexible PCB as shown in Figure 5 at least, that is the side thickness of die that is used between the die of these flexible circuit panel products of stamping-out is at least 3.5mm, otherwise die wall can wear and tear because of wall thickness is thin, thereby causes blanking die normally to use.

In sum, adopt the composing structure of the existing flexible PCB of this kind, the composing utilance of monoblock sheet material (being the gross area of flexible circuit board finished product and the ratio of flexible PCB sheet material area) only is about 18%, and make flexible PCB sheet material to be fully used, cause the production cost height of flexible PCB, and unfavorable raising production capacity.

The utility model content

The purpose of this utility model is to provide a kind of continuously apart from the composing structure of flexible PCB at the defective that above-mentioned prior art exists, can improve sheet material the composing utilance so that sheet material be fully utilized.

For achieving the above object, provided by the utility model is a collection of L shaped flexible PCB of arranging on a flexible PCB sheet material apart from the composing structure of flexible PCB continuously.These flexible PCBs are divided into some flexible PCB groups, these flexible PCB groups are distributed on the flexible PCB sheet material with array format, flexible PCB in each flexible PCB group is with just L shaped and fall L shaped continuously apart from arranging, and the long limit with flexible PCB is adjacent, minor face is positioned at flexible PCB group two ends, make each flexible PCB group roughly rectangular, and stamping-out have tear line between adjacent flexible PCB.

As mentioned above, the utility model is by designing apart from setting type continuously flexible PCB, eliminated the spacing between the adjacent flexible PCB in the prior art, thereby improved the composing utilance of flexible PCB sheet material, made full use of flexible PCB sheet material, make the production cost of flexible PCB reduce, production capacity improves.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 1, the utility model is continuously apart from the composing structure of flexible PCB, comprise a collection of L shaped flexible PCB 11 that is arranged on the flexible PCB sheet material 100, these flexible PCBs 11 are divided into some flexible PCB groups 10, and these flexible PCB groups 10 also are distributed on the flexible PCB sheet material 100 with array format.

See also Fig. 2, flexible PCB 11 in each flexible PCB group 10 is with just L shaped and fall L shaped continuously apart from arranging, and the long limit with flexible PCB 11 is adjacent, minor face is positioned at flexible PCB group 10 upper/lower terminals, make each flexible PCB group roughly rectangular, and 11 stamping-outs of adjacent flexible PCB have tear line 12.In the present embodiment, each flexible PCB group 10 comprises six flexible PCBs 11, and wherein three flexible PCBs 11 are arranged with just L shaped distance continuously, and three flexible PCBs 11 are L shaped continuously apart from arranging to fall in addition.When needs use single flexible PCB 11, only need to get final product in the flexible PCB sheet material 100 upper edge tear lines 12 single flexible PCB 11 of tearing.

Corresponding above-mentioned flexible PCB 11 continuously apart from arrangement mode, flexible PCB manufacturer can be designed to the straight edge of a knife 21 with being used for punch that stamping-out goes out tear line 12 edge of a knife towards pin 20, as shown in Figure 4, make punch all form the stamping-out edge of a knife 21 towards the two relative side of the pin edge of a knife, can in the stamping-out course of processing of flexible PCB, carry out bilateral stamping-out thus, promptly once can go out two tear lines 12 towards pin 20 for one.Corresponding this improvement design towards the pin edge of a knife, the pin 20 that dashes that is used for stamping-out flexible PCB 11 only needs arranging of corresponding flexible PCB 11 and roughly arranges at interval, make thus adjacently to have enough spacings, thereby make and when finishing blank operation and for the later operation that repairs a die, bring facility on the space with the pairing blanking die of the utility model towards between the pin 20.

As mentioned above, the improvement emphasis of the arrangement mode of 100 pairs of flexible PCBs 11 of the utility model flexible PCB sheet material ties up in adjacent the arranging in long limit with flexible PCB 11, promptly adopts continuously the mode of distance that flexible PCB 11 is arranged.Compare the spacing between the adjacent flexible PCB in the prior art and be at least the arrangement mode of 3.5mm, the utility model flexible PCB sheet material 100 has been eliminated this spacing, significantly improved the composing utilance of flexible PCB sheet material, thereby made full use of flexible PCB sheet material, make the production cost of flexible PCB reduce, production capacity improves.Measurement data is indicated, the same flexible PCB of processing and manufacturing on the flexible PCB sheet material of same area, composing utilance of the present utility model has reached about 50%, compares with the composing structure of existing flexible PCB sheet material, and increasing operation rate reaches about 30%.
