Description

Technical Field

[0001] The present invention relates to the technical field of backlight structures, and in particular to an FPC structure for improving lamp shadow and a method thereof. Background Art

[0002] The light source of the backlight is formed by the light emitting diode entering through the side of the light guide plate and then evenly dispersing the light. The light emitting diode chip is on the FPC, and the FPC and the light guide plate are fixed together with double-sided tape. Because the tape will focus the light, it will often hollow out the tape in front of the light emitting diode. Because the FPC material is relatively soft, the FPC with the hollowed-out tape part will not fit tightly with the light guide plate, causing the light of the light emitting diode to be unable to enter the light guide plate normally, resulting in poor light shadow at the light emitting port of the light emitting diode.

[0003] To avoid the above problems, a reinforcement structure is added to the back of the FPC, and the FPC is covered with copper foil to increase the stiffness of the FPC and prevent it from deforming. This design of covering the FPC with copper foil will also improve the heat dissipation capacity of the FPC. After the structure is changed, the traditional fixing method is used: there is no tape in front of the light-emitting diode to fix the FPC and the light guide plate. Because the FPC is covered with copper foil and has reinforcement on the back, it will become hard and the FPC will not deform. The light-emitting diode on the FPC can normally guide the light into the light guide plate, maintaining a good light and shadow effect.

[0004] In order to improve the processing flow of this type of FPC reinforcement structure, an FPC structure for improving lamp shadow and a method thereof are proposed to solve the above-mentioned problems and improve processing efficiency. Summary of the invention

[0005] In order to solve the technical problem that the FPC and the light guide plate are fixed with tape as proposed in the background technology, and as the FPC board and the light emitting diode are used, the FPC and the light guide plate cannot be tightly fitted, which eventually leads to poor light shadow of the light emitting diode, the present invention provides an FPC structure and method for improving the light shadow.

[0051] Example 2: Combination Figure 1-Figure 4 Based on Example 1, this embodiment is further improved in that:

[0052] The abutment mechanism includes a movable plate 16, which is movable in the middle area of ​​the two conveyor belts 15. A horizontal groove 17 is symmetrically opened in the middle of the movable plate 16. A slide plate 18 is connected to the two horizontal grooves 17 in a relatively horizontal sliding manner.

[0056] As the two threaded sleeves 7 move inward synchronously, the connecting rod 8 slides inward and drives the two outer hinged rods 23 to utilize the hinge of the middle round block 24 to synchronously pull the inner sliding rod 22 that is slidably connected to the outer hinged rod 23, which can drive the slide plate 18 at the horizontal groove 17 to perform adaptive displacement changes, so that the rubber wheel 20 at the bottom end can adapt to the size of the FPC board 50 to perform horizontal displacement changes, and under the action of the multiple retractable rubber wheels 20 at the bottom end, the FPC board 50 being processed can be adapted to rolling contact, ensuring the flatness of the FPC board 50 during processing.

[0057] Example 3: Combination Figure 5 , Figure 6 and Fig.10 Based on Example 1 and Example 2, this embodiment is further improved in that:

[0058] The flipping mechanism includes a horizontal plate 25, which is fixedly connected to the middle of one side of the workbench 1, and a frame plate 26 is fixedly connected to the outer side of the horizontal plate 25. Vertical grooves 27 and circular grooves 28 are successively opened on both sides of the inner wall of the frame plate 26, wherein the vertical groove 27 is arranged close to the workbench 1.

[0059] A slide bar 29 is vertically slidably connected in the vertical groove 27, a rotating block 30 is rotatably connected to the middle of the slide bar 29, a round rod 31 is fixedly connected to the middle of the rotating block 30, a starting clamping arm 32 is fixedly connected to the round rod 31 near the workbench 1, a connecting tube 38 is fixedly connected to the other end of the round rod 31, and an air pipe 39 is fixedly connected to one end of the connecting tube 38, a section of the air pipe 39 near the connecting tube 38 is made of hard material, specifically, a damping rubber is provided at the rotating connection between the rotating block 30 and the round rod 31, and the outer end of the air pipe 39 is made of soft material.

Specifically, as the entire round rod 31 rises, the sliding protrusion 34 will It is meshed with rack plate 1 43 and rack plate 2 44 in sequence, and after two meshing transmissions, the entire starting clamping arm 32 rotates 180°. Specifically, after gear 3 35 rises once and meshes with rack plate 1 43, the starting clamping arm 32 rotates 90°, and when it slides along the circular groove 28 to the descending section, gear 3 35 descends once and meshes with rack plate 2 44, and rotates 90° along the original rotation direction to complete the clamping and flipping of the FPC board 50.

[0062] The implementation principle of an FPC structure and method for improving lamp shadow in the embodiment of the present application is as follows:

[0063] As the conveyor belt 15 conveys the FPC board 50 to the starting clamping arm 32, the starting clamping arm 32 clamps and fixes one side of the FPC board 50, and then the motor 2 41 is started and, relying on the threaded connection between the screw rod 42 and the threaded sleeve block 2 40, the threaded sleeve block 2 40 can be used to pull the entire air pipe 39 and the starting clamping arm 32 to move vertically upward. As the rotating block 2 36 moves vertically upward, the side slider 37 and the circular groove 28 and the sliding connection between the slide bar 1 29 and the vertical groove 27 are relied on to maintain the stability of the movement. After the rotating block 2 36 rises to a certain extent, the gear 3 35 It can be meshed and connected with the rack plate 1 43, and after rising to the top, it can be flipped 90°, and enter the top with the sliding connection between the circular groove 28 and the side slider 37, and guide the side slider 37 to slide to the other side, so that the sliding protrusion 34 is slidably connected with the side notch 33 and moves downward toward the workbench 1, and can be meshed and connected with the rack plate 2 44 as the downward displacement proceeds, and rotate 90° along the previous rotation direction to realize the flipping of the FPC board 50, and after the flipping is completed, the conveying mechanism will continue to clamp and fix the FPC board 50, and add a reinforcement structure to the back of the FPC board 50 under the action of the abutment mechanism.

Since the FPC board 50 has a high risk of soft deformation, the light emitted by the light-emitting diode 52 on the FPC board 50 will be emitted through the gap between the light-emitting board 51 and the deformed FPC board 50, resulting in poor light shadow. The FPC board 50 is a support for the light-emitting diode 52. The position of the FPC board 50 without circuits is covered with copper foil 53. At the same time, a reinforcement structure is added on the back of the FPC board 50 to prevent the FPC board 50 from deformation, thereby avoiding poor light shadow.
