Description

Technical Field

[0001] This utility model relates to the field of flexible display technology, specifically to an integrated fixture for programming and electrical testing of OLED flexible screen modules. Background Technology

[0002] OLED displays are displays made using organic light-emitting diodes. They also have self-emissive organic light-emitting diodes. OLED stands for Organic Light Emitting Diode. OLED screen display technology is different from traditional LCD display technology. It does not require a backlight and is composed of a very thin organic material coating and substrate. When current passes through, these organic materials emit light. Since no backlight is needed, OLED screens using flexible substrates can achieve a flexible structure that can be bent.

[0003] However, display modules require programming and electrical testing during production. Both programming and electrical testing require clamping the display modules. Existing fixtures require changing different fixtures to hold and position the display modules during programming and electrical testing, increasing the number of clamping operations and alignment time, which in turn increases the overall production time and reduces the production efficiency of display modules. Therefore, we need to propose an integrated fixture for programming and electrical testing of OLED flexible screen modules. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an integrated fixture for programming and electrical testing of OLED flexible screen modules, including a substrate 1 and a lifting mechanism 2 mounted on the substrate 1. The driving end of the lifting mechanism 2 is provided with a base plate 4 located below the substrate 1. The driving end of the lifting mechanism 2 is provided with multiple sets of adjustment mechanisms 3. The driving ends of the multiple sets of adjustment mechanisms 3 and the lower surface of the base plate 4 are provided with multiple sets of adsorption mechanisms 5 for fastening the flexible screen. The flexible screens of different specifications are clamped by the multiple sets of adsorption mechanisms 5.

[0024] A support mechanism 6 is provided on the lower surface of the base plate 4, which supports the flexible screen adsorbed by the adsorption mechanism 5.

[0025] Each of the multiple adsorption mechanisms 5 includes a fixed cylinder 51, an insertion rod 54, and a pneumatic suction cup 56. The lower end of the insertion rod 54 is fixedly connected to a connecting screw sleeve 57. The upper end of the pneumatic suction cup 56 has an external thread that is threaded to the connecting screw sleeve 57. The upper end of the insertion rod 54 is inserted into the lower end of the fixed cylinder 51.

[0026] In this embodiment, the connecting screw sleeve 57 is used to quickly fix the pneumatic suction cup 56 to the lower end of the insertion rod 54. On the one hand, it realizes the quick assembly and disassembly of the pneumatic suction cup 56, which is convenient for replacing the appropriate pneumatic suction cup 56 according to the specifications of the flexible screen, thus improving the versatility of the fixture. On the other hand, the threaded connection has strong stability, which can ensure that the pneumatic suction cup 56 is not easy to fall off during the adsorption of the flexible screen, avoid the displacement of the flexible screen due to the loosening of the pneumatic suction cup 56, and ensure the accuracy of burning and testing.

[0027] Two sets of limiting grooves 52 are provided on the outer side of the fixed cylinder 51. A limiting block 55 that slides in the limiting groove 52 is fixedly connected to the outer side of the upper end of the insertion rod 54. A spring 53 that abuts against the insertion rod 54 is provided in the inner cavity of the fixed cylinder 51.

[0028] Furthermore, the limiting block 55 slides within the limiting groove 52, which can precisely limit the movement direction of the insertion rod 54 within the fixed cylinder 51, preventing the insertion rod 54 from deviating and ensuring that the pneumatic suction cup 56 always maintains a stable adsorption posture. At the same time, the resisting action of the spring 53 can provide a buffering force. When the pneumatic suction cup 56 contacts the flexible screen, the spring 53 is compressed, thereby avoiding rigid contact from causing pressure damage to the surface of the flexible screen, protecting the integrity of the flexible screen, and reducing product damage.

[0029] The lifting mechanism 2 includes a lifting cylinder 21 mounted on the upper surface of the base plate 1. The telescopic end of the lifting cylinder 21 passes through the base plate 1 and is fixedly connected to a connecting seat 22. A fixing plate 23 is fixedly connected to the lower surface of the connecting seat 22. The fixing plate 23 is fixedly connected to the upper surface of the base plate 4. Multiple sets of guide rods 24 that pass through the base plate 1 are fixedly connected to the upper surface of the fixing plate 23.

[0030] In a further preferred embodiment, the lifting cylinder 21 serves as a driving source, providing stable and adjustable lifting power to enable the base plate 4 to drive the flexible screen to accurately approach or move away from the programming and testing equipment, meeting the strict distance requirements during programming and testing. Secondly, multiple sets of guide rods 24 penetrate the substrate 1, effectively limiting the lifting trajectory of the fixed plate 23, preventing the base plate 4 from tilting during the lifting process, ensuring that the flexible screen always remains horizontal, and further improving the stability of programming and testing.

[0031] Each of the multiple adjustment mechanisms 3 includes an adjustment cylinder 31 installed on the upper surface of the fixed plate 23, and each set of adjustment cylinders 31 has a movable seat 32 installed at its telescopic end. The upper surface of the base plate 4 is provided with a slide groove 41 for sliding multiple sets of fixed cylinders 51, and the upper end of the slide groove 41 is fixedly connected to a guide beam 42 for sliding the movable seat 32.

[0032] Preferably, the adjusting cylinder 31 can drive the movable seat 32 to slide along the guide beam 42, thereby driving the fixed cylinder 51 to move within the slide groove 41, realizing the position adjustment of the adsorption mechanism 5. This can adapt to flexible screens of different sizes and interface positions, greatly improving the applicability of the fixture. The dual guiding effect of the guide beam 42 and the slide groove 41 can ensure that the adsorption mechanism 5 moves smoothly and is accurately positioned during the adjustment process, avoiding uneven force on the flexible screen due to the offset of the adsorption mechanism 5, and ensuring the smooth progress of subsequent burning and testing.

[0033] The support mechanism 6 includes a corrugated pipe 61 fixedly connected to the middle of the lower surface of the base plate 4. An airbag 62 is provided at the lower end of the corrugated pipe 61, and an air pipe 65 is provided at the upper outer end of the corrugated pipe 61.

[0034] Secondly, the corrugated tube 61 has good elasticity, and the airbag 62 can evenly contact the back of the flexible screen after inflation, providing stable support for the flexible screen and preventing deformation of the flexible screen due to insufficient force during burning, thus preventing the flexible screen from shaking. At the same time, the flexible material of the airbag 62 will not scratch the flexible screen. The air tube 65 makes it easy to accurately control the inflation amount of the airbag 62, thereby adjusting the support force and meeting the different support force requirements of flexible screens of different specifications.

[0035] Multiple sets of protrusions 63 are fixedly connected to the lower outer end of the corrugated pipe 61, and telescopic rods 64 are fixedly connected to the upper surface of the multiple sets of protrusions 63. The upper end of the telescopic rods 64 is fixedly connected to the lower surface of the base plate 4.

[0036] In addition, multiple sets of telescopic rods 64 are evenly distributed on the outside of the bellows 61, which can limit the extension and retraction direction of the bellows 61 and prevent the airbag 62 from shifting or tilting when it comes into contact with the flexible screen. At the same time, the telescopic rods 64 work together with the bellows 61 to further enhance the load-bearing capacity of the support mechanism 6, ensuring that even if the airbag 62 is subjected to slight external force interference during the burning test, it can still maintain a stable support state, ensure the position of the flexible screen is fixed, and improve the accuracy of the test data.

[0037] In use, the position of the cylinder 31 relative to the movable seat 32 is controlled and adjusted according to the specifications of the flexible screen, thereby facilitating the adjustment of the position of the adsorption mechanism 5 below the movable seat 32. This allows multiple adsorption mechanisms 5 to be adapted to the flexible screen, improving the applicability of the device. The lifting cylinder 21 drives the base plate 4 on the fixed plate 23 to move synchronously, causing the pneumatic suction cups 56 on the multiple adsorption mechanisms 5 to adhere to the flexible screen. At the same time, the pneumatic suction cups 56 apply pressure to the insertion rod 54, causing the insertion rod 54 to compress the spring 53 for buffering, avoiding rigid contact that could damage the flexible screen. After the lifting cylinder 21 resets, it clamps and picks up the flexible screen. At this time, air is introduced into the air pipe 65 through an external air source, filling the airbag 62 and the corrugated pipe 61. The airbag 62 can adhere evenly to the flexible screen, thus supporting the flexible screen and preventing pressure on the spring 53 during the gripping and moving process. This also prevents the flexible screen from shaking during programming and electrical testing, thereby improving the efficiency of programming and electrical testing of the flexible screen.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
