Description

Technical Field

[0001] This invention specifically relates to a pressure-holding fixture for a diffusion plate based on double-sided adhesive. Background Technology

[0002] In the backlight module of an LCD display, the diffuser plate is a key optical component. Its function is to scatter the line or point light source guided by the light guide plate, forming a uniformly bright surface light source, thereby improving the uniformity and visual effect of the displayed image. Currently, the diffuser plate is usually fixed to the frame or other components of the backlight module using double-sided adhesive. To ensure the reliability and flatness of the adhesion, a "pressure holding" operation is required after adhesion. This involves applying and maintaining a constant pressure on the diffuser plate for a period of time, allowing the double-sided adhesive to fully contact, release air, and wet the adhesive surface, achieving the designed adhesive strength.

[0003] Existing pressure-holding operations mostly rely on manual pressing using simple jigs. The pressure-holding process depends entirely on the operator's manual force application, and the amount of pressure applied varies from person to person, making it difficult to maintain consistency. After pressure holding, the operator cannot objectively and intuitively judge whether sufficient pressure has been applied or whether pressure holding is complete. The entire process is somewhat blind. Due to uneven and unstable pressure holding, the diffuser plate is easily not firmly attached or stress warping occurs, ultimately affecting the display effect. To address this, we propose a diffuser plate pressure-holding jig based on double-sided adhesive. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0035] The limiting block 7 is provided on one side of the pressure retaining block 2 to position when the pressure is retained.

[0036] The core beneficial effect of the feedback system combining mechanical and electronic is to convert the abstract "pressing force" into intuitive "light signal", which fundamentally solves the inconsistent pressure problem caused by relying on artificial feeling, ensures that every product can reach the minimum and uniform pressure standard, and significantly improves the consistency and reliability of product quality.

[0037] Preferably, the elastic guide assembly 6 comprises a guide rod 61, a limiting cap 62, an external thread 63 and a spring 64, the guide rod 61 is slidingly installed inside the handle 1, the outer surface of the guide rod 61 is sleeved with the spring 64 which abuts against the pressure maintaining block 2, the pressure maintaining block 2 is provided with a threaded groove 21 matched with the external thread 63 at the lower end of the guide rod 61, and the guide rod 61 has the limiting cap 62 at one end;

[0038] The guide rod 61 ensures the stability and linearity of the pressing process, preventing the pressure maintaining block 2 from tilting; the spring 64 provides controllable and linear pressure maintaining force; through the cooperation of the threaded groove 21 and the external thread 63 at the lower end of the guide rod 61, the pre-tightening force or working stroke of the spring 64 can be adjusted, thereby allowing the pressure maintaining force required for triggering the signal to be adjusted according to different process requirements, enhancing the versatility of the jig.

[0039] Preferably, the outer diameter of the guide rod 61 is three-section structure, and the outer diameter of the end of the guide rod 61 close to the limiting cap 62 is the largest.

[0040] It is convenient to limit the reset elongation of the spring 64 by the limiting cap 62, ensuring the position determination of the handle 1 after reset.

[0041] Preferably, the limiting block 7 is "L" shaped;

[0042] It is convenient to contact with the side wall of the pressure maintaining back plate during use to achieve fast and accurate positioning, so that the pressure maintaining block 2 contacts with the diffusion plate.

[0043] Preferably, the power supply assembly 4 comprises a battery 41, a conductive sheet 42 and a conductive wire 43, the inside of the handle 1 along the long side is provided with the conductive wire 43 electrically connected with the lamp bead 5, and one side of the conductive rod 3 is connected with the conductive wire 43 through a cable, the battery 41 is arranged at the middle part of the inside of the pressure maintaining block 2, and the both ends of the battery 41 have the conductive sheet 42 corresponding to the conductive rod 3;

[0044] All circuit elements are integrated inside the jig without affecting the operation; the contact design of the conductive sheet 42 and the battery 41 provides a stable and reliable circuit connection point, ensuring that the circuit can be instantly turned on when the conductive rod 3 is contacted, and the triggering signal is accurate and reliable.

[0045] Preferably, the conductive sheet 42 includes a conductive portion 421, a conductive electrode 422, and a mounting hole 423. The conductive electrode 422 is fixed to one end of the conductive portion 421 and is in contact with the battery 41. An installation hole 423 is provided on the inner side of the conductive portion 421 to cooperate with the pressure-holding block 2;

[0046] The mounting hole 423 facilitates firmly fixing the conductive sheet 42 to the pressure-holding block 2; the conductive electrode 422 ensures good contact with the electrode plate of the battery 41, reduces the contact resistance, and ensures the stability of the circuit operation.

[0047] Preferably, both the conductive rod 3 and the power supply component 4 are provided in two places, and the conductive rod 3 is engaged with the handle 1 through a threaded portion;

[0048] A symmetrical dual-channel trigger circuit is formed. This design can ensure that the circuit will only conduct the trigger signal when the pressure on both sides reaches the preset value, thus ensuring that the pressure applied by the pressure-holding block 2 on the diffusion plate is absolutely uniform, and avoiding uneven pasting or component warping caused by unilateral force.

[0049] Preferably, the handle 1 is in a "冂" shape;

[0050] It is convenient to provide an ample holding space.

[0051] Preferably, a horn 8 electrically connected to the conductive rod 3 is provided on the handle 1, and the horn 8 is staggered from the lamp bead 5;

[0052] A sound and light dual-alarm mechanism is provided. In a noisy industrial environment or when the operator's line of sight is blocked, the auditory signal can more effectively prompt the completion of pressure holding, greatly improving the reliability of the prompt and the error tolerance rate of the operation..

[0053] Preferably, a wear-resistant layer is fixedly adhered to the lower surface of the pressure-holding block 2;

[0054] The wear-resistant layer material is preferably polytetrafluoroethylene, which is convenient for reducing the large rigid collision on the diffusion plate during the pressure-holding process, and is easy to disassemble, maintain and replace the wear-resistant layer after later wear, extending the service life of the pressure-holding block 2.

[0055] The working principle and use process of the present application: the operator holds the handle 1 of the jig, aligns the pressure-keeping block 2 below the jig with the diffusion plate component to be kept, and presses the handle 1 downward to make the handle 1 slide downward along the guide rod 61 against the elastic force of the spring 64 in the elastic guide assembly 6, so that the spring 64 is compressed and the reaction force generated by the spring 64 is evenly transmitted to the diffusion plate below through the pressure-keeping block 2 to keep the pressure. When the handle 1 is continuously pressed to a preset position, it means that the spring 64 is compressed to a certain stroke, at which time the pressure-keeping force has reached the preset minimum required value. At the same time, the conductive rod 3 fixed to the lower end of the inner side of the handle 1 comes into contact with the conductive sheet 42 of the power supply assembly 4 fixed to the pressure-keeping block 2. The contact between the conductive rod 3 and the conductive sheet 42 makes the circuit closed to form a path, and the current flows from the battery 41 to the lamp bead 5 and / or the horn 8 through the conductive sheet 42, the conductive rod 3 and the conductive wire 43. At this time, the lamp bead 5 emits light or the horn 8 emits sound, providing the operator with clear visual or audible signals that enough pressure-keeping force has been applied, and the pressure-keeping operation is completed.
