Description

Technical Field

[0001] This utility model relates to the field of driving circuit board technology for liquid crystal panels, specifically a quick-change mechanism for FFC and LVDS signal line devices that does not require disassembly. Background Technology

[0002] The existing method for inserting signal lines into the FFC / FPC / LVDS connectors on the driver circuit board (PCB) of LCD panels involves manually opening the connector's movable cover, inserting the FFC by hand until it is properly aligned, and then closing the movable cover. (See attached image.) Figure 1 As shown. After testing, the connector's movable cover is manually opened and the FFC removed. Although a fully automatic insertion and alignment compensation mechanism has been designed to meet customer production needs, when customer orders are small and varied, multiple size changes are often required. To accelerate product changeover time, improvements to the cover opening / closing mechanism and the FFC quick-change clamping assembly are necessary. In summary, the existing method has the following main shortcomings:

[0003] (1) Manual operation is labor-intensive and difficult to implement stably when it is not easy to recruit personnel;

[0004] (2) Each circuit board has two FFC connectors. Only one connector can be worked on manually at a time. Each circuit board needs to be worked on twice, which makes the work time longer.

[0005] (3) When personnel switch between products with large differences in size and model, they need to be trained. This is not easy for companies with high staff turnover, and frequent changes can also waste time and costs. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned shortcomings by providing a quick-change mechanism for FFC and LVDS signal line devices that does not require disassembly. This mechanism can save overall process time, significantly improve production efficiency, and solve the problems of wasted time, manpower, and long operating time associated with manual operation.

[0007] To achieve the above objectives, a quick-change mechanism for FFC and LVDS signal cable devices without disassembly is designed, including a connecting base 4, an airtight base 5, a non-disassembly clamping block 6, a cover plate 7, and a small cylinder 8.

The front of the non-removable clamping block 6 is provided with a front square groove 603, which is used to put the LVDS wire 3 in and work together with the airtight base 5 and the small cylinder 8 to clamp the LVDS wire securely.

[0009] Furthermore, a milled groove is provided at the top square groove 601 of the non-disassembly clamping block 6, and the step formed by the milled groove increases the stability during locking.

The cover plate base 505 is connected to the cover plate 7 and is powered by the small cylinder 8 to perform the cover-pulling action.

[0011] Furthermore, a cylinder connecting groove 504 is provided above the cylinder mounting base 503. The cylinder connecting groove 504 is used to lock the front thread of the small cylinder 8, thereby further improving the stability of the overall structure.

[0012] Furthermore, a linear slide rail 506 is provided on the side of the extended base 501. The linear slide rail 506 is fixed to the side inclined groove 602 of the non-removable clamping block 6. The linear slide rail 506 is used to increase the stability of the operation of the small cylinder 8.

[0013] Furthermore, the cover plate 7 is configured as a fixed-axis movable type, and the cover plate 7 can move back and forth 90 degrees under the drive of the small cylinder 8, thereby achieving the action of lifting the cover.

[0014] Furthermore, the top of the connecting base 4 is connected to the image alignment correction system 100 and the opening and closing cover mechanism 200. After the bottom of the connecting base 4 is added with an air hole, it is connected to the FFC quick-change clamping assembly 300.

[0033] This utility model is mainly applied to the LCD panel screen illumination test process, belonging to the automatic wiring device of automatic screen detection equipment.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0035] As attached Figure 3a and attached Figure 3bAs shown, the PCB contact is the main actuation product, so it will not be described in detail; FFC & FPC are the main actuation cables, so they will not be described in detail; LVDS are the main actuation cables, so they will not be described in detail. The connecting base mainly connects the image alignment and correction system and the opening and closing cover mechanism, and connects to the FFC quick-change clamping assembly after adding an air hole at the bottom. The top of the airtight base is combined with the connecting base, containing a sealing ring, air pipe connector and cylinder fixing seat, and the bottom is combined with the non-removable clamping block. The non-removable clamping block is an integrated cable clamping block, which can replace the cable according to the customer's product requirements, and uses locking screws to clamp the FFC & FPC and the power provided by the small cylinder to clamp the LVDS and other cables. Only the cable needs to be replaced, without the need to disassemble the cable fixing parts and air pipes and other accessories. The cover lever is fixed to the non-removable clamping block and has a fixed axis that can move 90 degrees back and forth, thereby achieving the opening and closing action of the cover. A small cylinder is locked to the tail of the non-removable clamping block, providing forward and backward power to clamp the LVDS cable.

[0036] In the non-disassembly clamping block, the top square slot is an integral design, combining with the connecting base and cleverly utilizing steps through milling to increase stability during locking. The side beveled slots are used to fix the claw-type clamp and, during claw clamping operation, maintain the clamping force by fixing the movement track, thus preventing gaps caused by track misalignment during clamping, which could lead to wire deformation due to wear and tear, affecting clamping stability. The front square slot is used to insert LVDS power cables with rigid injection-molded handles, and works in conjunction with the airtight base and small cylinder to securely clamp the LVDS cable.

[0037] In the airtight base, the bottom of the extension base is connected to the cylinder mounting base, and the front end is connected to the cover plate base and FFC / FPC wire clamps. Powered by a small cylinder, the cover plate base moves forward, effectively clamping the power cords of LVDS and other rigid injection-molded handles in conjunction with the non-removable clamping block. The FFC / FPC wire clamps, with their side grooves, clamp the flexible FFC / FPC wires, preventing frequent insertions and wire displacement that could reduce insertion and lighting yield. The cylinder mounting base primarily connects to the small cylinder, serving as the reference base. The cylinder connecting groove primarily secures the threaded front end of the small cylinder. The cover plate base primarily connects the cover plate and the extension base, and the small cylinder performs the cover-pulling action. A linear guide rail is fixed to the side groove of the non-removable clamping block, increasing stability when the small cylinder pushes the cover.

[0038] The operation of this utility model can be carried out in the following steps: Select the corresponding signal cable according to the product requirements; fix the corresponding signal cable under the suction cup in the FFC quick-change clamping assembly; use the image alignment correction system to take a picture of the signal cable insertion port of the product and correct the angle of the overall mechanism; adjust the robot arm cable insertion origin position compensation according to the offset of the image alignment correction system's picture data compared with the origin; move the overall mechanism to the insertion position, and the FFC quick-change clamping assembly performs the insertion action; after the insertion is completed, power on the signal cable and light it up; after the test screen is completed, the FFC quick-change clamping assembly retracts the signal cable; the overall mechanism leaves the insertion position.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art. The standard parts used can be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology, and the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.

[0040] This utility model is not limited to the above-described embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of this utility model shall be considered equivalent substitutions and shall be included within the protection scope of this utility model.
