Description

Technical Field

[0001] This invention belongs to the field of flexible OLED display processing technology, specifically relating to an arc-shaped bonding mechanism. Background Technology

[0002] Flexible OLED displays, also known as flexible displays, are bendable, ultra-thin display devices made from plastic substrates. They possess physical properties such as high temperature resistance, pressure resistance, and roll resistance, thus showing broad application prospects in various fields. However, because flexible OLED display modules are only 0.9mm thin, they must be bonded to rigid, curved products during the manufacturing process. Due to the lightweight and thin nature of flexible OLED display modules, the back and four sides of the product cannot be touched, as this can easily lead to wear and tear, causing display defects or even direct damage to the panel. Manual bonding also has inherent defects, introducing numerous instabilities that can affect the quality and lifespan of the LCD screen.

[0003] Traditional manual bonding methods rely on experience and visual inspection for alignment, which is inefficient, inconsistent, and the bonding results can vary depending on the individual experience of the inspectors, making it difficult to achieve standardized production. Summary of the Invention

[0004] The purpose of this invention is to provide an arc-shaped fitting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an arc-shaped bonding mechanism, comprising a moving component, a display module fixture, and a cylindrical fixture for bonding a flexible OLED display screen. The moving component includes an X-axis moving mechanism, a Z-axis moving mechanism, and an R-axis rotating mechanism. The X-axis moving mechanism drives the Z-axis moving mechanism to reciprocate along the X-axis, the Z-axis moving mechanism drives the R-axis rotating mechanism to reciprocate along the Z-axis, and the R-axis rotating mechanism drives the cylindrical fixture to rotate along a preset axis. The display module fixture is located below the cylindrical fixture, and the top of the display module fixture is recessed to form a groove that matches the flexible OLED display.

[0006] Preferably, the arc-shaped bonding mechanism further includes pressure-holding components, which are distributed sequentially along the length direction of the X-axis moving mechanism, and pressure-holding spaces are formed on the pressure-holding components to maintain pressure on the bonded flexible OLED display.

A top plate is fixedly connected between the two rotating plates, and a second electric push rod is fixedly connected to the top plate. A second moving rod is connected to the telescopic end of the second electric push rod, and an arc-shaped frame is fixedly connected to the free end of the second moving rod.

[0011] Preferably, motors are fixedly connected to both sides of the arc-shaped fixture, and rotating plates are connected to the output ends of the two motors.

[0014] Preferably, side plates are fixedly connected to both sides of the base, and fixing screws are screwed onto the side plates.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention drives the cylindrical fixture to move through the X-axis moving mechanism, the Z-axis moving mechanism and the R-axis rotating mechanism, thereby allowing the cylindrical fixture to drive the flexible OLED display to be bonded, thereby improving the production efficiency of the flexible OLED display, improving the bonding accuracy and consistency, reducing human factors affecting product quality and reducing the pollution of the product in the production process.

[0016] (2) Based on the above-mentioned beneficial effects, the present invention further improves the production efficiency of the device by using the arc groove on the arc fixture to maintain pressure on the flexible OLED display after bonding.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 As shown, the present invention provides the following technical solution: An arc-shaped bonding mechanism includes a moving component, a display module fixture 2, and a cylindrical fixture 1 for bonding a flexible OLED display. The moving component includes an X-axis moving mechanism 6, a Z-axis moving mechanism 7, and an R-axis rotating mechanism 8. The X-axis moving mechanism 6 drives the Z-axis moving mechanism 7 to reciprocate along the X-axis, the Z-axis moving mechanism 7 drives the R-axis rotating mechanism 8 to reciprocate along the Z-axis, and the R-axis rotating mechanism 8 drives the cylindrical fixture 1 to rotate along a preset axis. The display module fixture 2 is disposed below the cylindrical fixture 1, and the top of the display module fixture 2 is recessed to form a groove that matches the flexible OLED display.

[0022] With the above technical solution, when personnel need to bond a flexible OLED display, the flexible OLED display to be processed is placed inside the display module fixture 2. After the flexible OLED display is placed, the X-axis moving mechanism 6, the Z-axis moving mechanism 7, and the R-axis rotating mechanism 8 work. The X-axis moving mechanism 6 drives the Z-axis moving mechanism 7 to move along the X-axis. The Z-axis moving mechanism 7 then drives the R-axis rotating mechanism 8 to move along the Z-axis, thereby moving the cylindrical fixture 1 to the position required by the personnel. After the position of the cylindrical fixture 1 is adjusted, the R-axis rotating mechanism 8 drives the cylindrical fixture 1 to rotate. When the R-axis rotating mechanism 8 rotates, the Z-axis moving mechanism 7 drives the rotating cylindrical fixture 1 to move down synchronously. The cylindrical fixture 1 then bonds the flexible OLED display in the display module fixture 2.

[0023] In addition, in order to facilitate the movement of the flexible OLED display screen and to maintain pressure on the bonded flexible OLED display screen, the bonding mechanism also includes a pressure holding member 5. The pressure holding member 5 is distributed sequentially along the length direction of the X-axis moving mechanism 6, and a pressure holding space is formed on the pressure holding member 5 to maintain pressure on the bonded flexible OLED display screen. The cylindrical fixture 1 has multiple suction cups 10 on its circumferential surface for adsorbing and bonding the flexible OLED display screen.

[0024] In this embodiment, after the flexible OLED display is bonded, the suction cup 10 works to adsorb the flexible OLED display. The X-axis moving mechanism 6, the Z-axis moving mechanism 7, and the R-axis rotating mechanism 8 work to drive the Z-axis moving mechanism 7 to move along the X-axis. The Z-axis moving mechanism 7 then drives the R-axis rotating mechanism 8 to move along the Z-axis, thus moving the cylindrical fixture 1 above the pressure holding member 5. The Z-axis moving mechanism 7 then moves the cylindrical fixture 1 downward, thus moving the bonded flexible OLED display into the pressure holding space on the pressure holding member 5, where the pressure holding space holds the flexible OLED display.

[0025] Specifically, in one embodiment, regarding the aforementioned display module fixture 2, in order to adjust the position of the display module fixture 2 when supporting the flexible OLED display, such as... Figures 1-4 As shown, it also includes a fixture base 3, which is installed at the bottom of the display module fixture 2, and a precision adjuster 4 is provided between the display module fixture 2 and the fixture base 3.

[0026] In this embodiment, after the flexible OLED display screen is placed inside the display module fixture 2, the precision adjuster 4 works to fix the fixture base 3 and the display module fixture 2 together, and the precision adjuster 4 corrects the parallelism between the display module fixture 2 and the X-axis.

[0027] Furthermore, in this invention, regarding the aforementioned pressure-holding member 5, as... Figures 5-7 As shown, the pressure holding component 5 includes an arc-shaped fixture 51, the top of which is recessed to form an arc-shaped groove 59 that matches the flexible OLED display after bonding.

[0028] In this embodiment, when personnel need to bond the flexible OLED display, the flexible OLED display is placed above the arc-shaped fixture 51, and the flexible OLED display is pressurized by the arc-shaped groove 59 on the arc-shaped fixture 51.

[0029] When the curved fixture 51 applies pressure to the flexible OLED display, in order to limit the top of the flexible OLED display, the following implementation method is provided in this invention:

[0030] Implementation

[0031] Motors 52 are fixedly connected to both sides of the arc-shaped fixture 51. The output ends of the two motors 52 are connected to rotating plates 53. A top plate 55 is fixedly connected between the two rotating plates 53. A second electric push rod 56 is fixedly connected to the top plate 55. A second moving rod 57 is connected to the telescopic end of the second electric push rod 56. An arc-shaped frame 510 is fixedly connected to the free end of the second moving rod 57.

[0032] In this embodiment, when the flexible OLED display is placed above the curved fixture 51, the curved groove 59 on the curved fixture 51 applies pressure to the flexible OLED display. The motor 52 operates, thereby driving the rotating plate 53 to rotate relative to the curved fixture 51. This, in turn, causes the second electric push rod 56 to rotate to an angle perpendicular to the ground. The second electric push rod 56 then drives the second moving rod 57 to move, which in turn drives the curved frame 510 to move, allowing the curved frame 510 to further apply pressure to the flexible OLED display.

[0033] Implementation

[0034] Motors 52 are fixedly connected to both sides of the arc-shaped fixture 51. The output ends of the two motors 52 are connected to rotating plates 53. The interior of the two rotating plates 53 is fixedly connected to first electric push rods 58. The telescopic ends of the two first electric push rods 58 are connected to first moving rods 54. A top plate 55 is fixedly connected between the free ends of the two first moving rods 54. A second electric push rod 56 is fixedly connected to the top plate 55. The telescopic end of the second electric push rod 56 is connected to a second moving rod 57. The free end of the second moving rod 57 is fixedly connected to an arc-shaped frame 510.

[0035] In this embodiment, when the flexible OLED display is placed above the curved fixture 51, the curved groove 59 on the curved fixture 51 applies pressure to the flexible OLED display. The motor 52 operates, driving the rotating plate 53 to rotate relative to the curved fixture 51. This causes the second electric push rod 56 to rotate to an angle perpendicular to the ground. The first electric push rod 58 then moves the first moving rod 54, which in turn moves the top plate 55 to the desired position. The second electric push rod 56 then moves the second moving rod 57, which in turn moves the curved frame 510, further applying pressure to the flexible OLED display.

[0036] In addition, in this invention, the bottom of the arc-shaped frame 510 protrudes outward to form an arc-shaped portion that matches the arc-shaped groove 59.

[0037] To support the fixture base 3, the arc fixture 51, and the X-axis moving mechanism 6, the fitting mechanism also includes a base 9, on which the fixture base 3, the arc fixture 51, and the X-axis moving mechanism 6 are all fixedly connected.

[0038] In this embodiment, the base 9 supports the fixture base 3, the arc fixture 51 and the X-axis moving mechanism 6, making the device more stable during operation.

[0039] When personnel need to fix the base 9, in order to make the base 9 easy to fix, such as Figures 1-3 As shown, side plates 11 are fixedly connected to both sides of the base 9 symmetrically, and fixing screws 12 are screwed onto the side plates 11.

[0040] In this embodiment, before using the device, the base 9 is placed at the position where it needs to be fixed, and the fixing screw 12 on the side plate 11 is rotated to move the fixing screw 12 relative to the side plate 11 until the fixing screw 12 enters into another object and abuts against the side plate 11, thereby fixing the base 9 and making the device more stable when it is working.

[0041] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
