Description

Technical Field

[0001] This application relates to the field of OLED product equipment technology, and in particular to a double-sided pressing device for OLED products. Background Technology

[0002] Currently, there are several types of crimping fixtures used for double-sided crimping of OLED screen products: 1) fixed pressure heads on both sides; 2) fixed pressure head on one side and multi-axis adjustment mechanism on the other side; 3) multi-axis adjustment mechanism on both sides. Correspondingly, the crimping methods are as follows: 1) alignment crimping using fixed pressure heads on both sides; 2) alignment crimping using a fixed pressure head on one side and adjustment via a multi-axis adjustment mechanism on the other side; 3) alignment crimping using multi-axis adjustment mechanisms on both sides.

[0003] However, all of the above methods have technical drawbacks. In the first method, since both sides use fixed pressure heads for alignment and pressing, after placing the OLED display on the pressing fixture and performing alignment compensation and pressing on side A, no alignment compensation is performed on side B, which is assumed to be already aligned and pressed directly. However, due to the slight deformation characteristic of OLED screens, when side A is aligned and pressed, pressing on side B directly may cause poor pressing due to the slight deformation of the OLED product, affecting the pressing accuracy of both sides. In the second method, after placing the OLED display on the pressing fixture and performing alignment compensation and pressing on side A, multi-axis adjustment is used to automatically align and press on side B of the OLED product. In the third method, both sides use a multi-axis adjustment mechanism for automatic alignment and pressing. In the second and third methods, although double-sided alignment crimping can be performed to improve the accuracy of double-sided crimping, the crimping fixture is equipped with a multi-axis adjustment mechanism, which requires a corresponding external electrical device to provide electrical power. When it is necessary to move and transport the crimped OLED product and the crimping fixture to the next process for aging test, there will be a need to continuously provide power to the crimping fixture, making it difficult to move the OLED product and the crimping fixture.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0058] Please see Figures 1 to 7 The double-sided pressing device for OLED products provided in this application includes:

[0059] The device comprises a jig support plate device 1, a double-sided pressing jig 2, a multi-axis automatic adjustment mechanism 3, and an optical alignment mechanism 4. The double-sided pressing jig 2 is located on the jig support plate device 1. The double-sided pressing jig 2 includes a support base plate 21, a fixed pressing head 22, and a magnetic adsorption pressing assembly 23. The fixed pressing head 22 and the magnetic adsorption pressing assembly 23 are respectively arranged on both sides of the support base plate 21. The multi-axis automatic adjustment mechanism 3 is installed on the jig support plate device 1. The multi-axis automatic adjustment mechanism 3 includes an electromagnet 31, a first pneumatic lifting magnet assembly 32, and an adjustment assembly 33. The adjustment assembly 33 is used to adjust the alignment of the OLED product. The electromagnet 31 and the first pneumatic lifting magnet assembly 32 are used to cooperate with the magnetic adsorption pressing assembly 23 to press the OLED product. The optical alignment mechanism 4 is located below the jig support plate device 1 and is used to position the OLED product and control the multi-axis automatic adjustment mechanism 3 and the double-sided pressing jig 2 to adjust in real time according to the position of the OLED product to achieve double-sided alignment pressing of the OLED product.

[0060] The double-sided pressing fixture 2 is detachably and fixedly connected to the fixture support plate device 1, for example, by means of snap-fit ​​or clamp fixation. Specifically, a fixing pressure head 22 is installed at the first end of the upper surface of the support base plate 21, and a magnetic adsorption pressing assembly 23 is installed at the second end. The fixing pressure head 22 presses the A side of the OLED screen, and the magnetic adsorption pressing assembly 23 presses the B side of the OLED screen, thereby completing the double-sided pressing of the OLED screen. The support base plate 21 is detachably and fixedly connected to the fixture support plate device 1. It should be noted that the fixing pressure head 22 can be a pressure head of existing technology, which will not be described in detail here.

[0061] The fixture support plate device 1 is hollow, and a transparent substrate 24 is provided on the support base plate 21 of the double-sided pressing fixture 2. This transparent substrate 24 can be made of transparent quartz glass or other transparent materials, allowing the optical alignment mechanism 4 below the fixture support plate device 1 to visually align the OLED product fixed above the double-sided pressing fixture 2 through the hollow space above and the transparent substrate 24. Furthermore, the transparent substrate 24 also provides support for the OLED product, reducing the possibility of deformation during the pressing of flexible OLED products and improving the pressing effect. In one possible embodiment, the transparent substrate 24 may not be provided on the support base plate 21 of the double-sided pressing fixture 2; instead, through holes may be directly formed on the support base plate 21, allowing the optical alignment mechanism 4 to perform visual alignment through the through holes, thus reducing production costs.

[0062] The multi-axis automatic adjustment mechanism 3 is mounted on the fixture support plate device 1 and is located at one end near the magnetic adsorption and pressing assembly 23. Specifically, the electromagnet 31 of the multi-axis automatic adjustment mechanism 3 is located above the magnetic adsorption and pressing assembly 23 to facilitate the adsorption of the magnetic adsorption and pressing assembly 23 below.

[0063] In this embodiment, during OLED product crimping, firstly, the unloaded double-sided crimping fixture 2 is moved onto the fixture support plate device 1, and the double-sided crimping fixture 2 is positioned and fixed by the fixture support plate device 1. At this time, the adjustment component 33 of the multi-axis automatic adjustment mechanism 3 on side B drives the electromagnet 31 to press down, and the magnet adsorbing the crimping component 23 is activated by the first pneumatic lifting magnet component 32. The electromagnet 31 works, adsorbing the magnet and lifting the crimping component 23. Then, the OLED product is moved above the double-sided crimping fixture 2, and the optical alignment mechanism 4 aligns the fixed pressure head 22 on side A with the OLED product to compensate for the X, Y, and θ directions of side A of the OLED product. After the alignment compensation is completed, the OLED product is placed on the double-sided crimping fixture 2, and the fixed pressure head 22 is pressed down to perform the crimping action, completing the crimping of side A of the OLED product. Specifically, the OLED product can be moved above the double-sided pressing fixture 2 by a robotic arm. Then, alignment is achieved through the cooperation of the optical alignment mechanism 4 and the robotic arm, compensating for the alignment of side A of the OLED product in the X, Y, and θ directions. Pressing is then performed by a fixed pressing head 22. After side A is pressed, the optical alignment mechanism 4 performs visual alignment between the magnetic adsorption pressing assembly 23 and side B of the OLED product, and the multi-axis automatic adjustment mechanism 3 compensates for the X, Y, and θ directions. After alignment compensation, the multi-axis automatic adjustment mechanism 3 controls the magnetic adsorption pressing assembly 23, which is attracted by the electromagnet 31, to press down and disconnect the magnetic adsorption between the electromagnet 31 and the magnetic adsorption pressing assembly 23. This allows the magnetic adsorption pressing assembly 23 to complete the pressing of side B of the OLED product, thus completing the double-sided pressing process. This achieves double-sided alignment pressing of the OLED product, automatic alignment of double-sided multi-segment pins, and improves the accuracy of double-sided pressing.

[0064] Furthermore, after completing the double-sided crimping process, a robotic arm can move the crimped double-sided crimping fixture 2 and the OLED product to the next working position, such as to the cavity of an aging equipment for aging testing, thus solving the problem of difficult movement of the double-sided crimping fixture 2. Compared to traditional crimping fixtures, the double-sided crimping fixture 2 of this application does not have a multi-axis automatic adjustment mechanism 3, solving the problem of its large size caused by the presence of the multi-axis automatic adjustment mechanism 3. In addition, the double-sided crimping fixture 2 does not require any pneumatic or power supply support during movement, and can directly send the double-sided crimping fixture 2 and the crimped OLED product into the aging equipment for aging testing, achieving automated operation.

[0065] Optionally, the magnetic adsorption pressing assembly 23 includes a magnetic switch, a magnetic pressing head 231, and an adhesive plate 232. The magnetic pressing head 231 is used to press the OLED product by magnetic adsorption. The magnetic switch is mounted on the support base plate 21 and connected to the magnetic pressing head 231. The magnetic switch is used to turn the magnetism of the magnetic pressing head 231 on / off. The magnetic pressing head 231 includes a magnetic element 2311 and a fixing block 2312. The magnetic element 2311 is mounted on the fixing block 2312. One end of the adhesive plate 232 is connected to the support base plate 21, and the other end is connected to the fixing block 2312.

[0066] The magnetism of the magnetic component 2311 can be controlled by a magnetic switch. The magnetic component 2311 can be a magnet or other magnetic object. A through hole adapted to the size of the magnetic switch is provided on the supporting base plate 21 for mounting the magnetic switch within the through hole; the magnetic switch is not shown in the attached drawings. The magnetic pressure head 231 may include several magnetic components 2311, such as two or three, etc., without specific limitation here. The bonding plate 232 is an elastic bonding plate 232, allowing the magnetic pressure head 231 connected to one end to be raised or lowered.

[0067] In this embodiment, two magnetic components 2311 are provided, respectively located at both ends of the fixing block 2312, to balance the downward pressure on both sides during pressing.

[0068] Optionally, the position of the electromagnet 31 corresponds to the position of the magnetic component 2311, and the electromagnet 31 is used to attract the magnetic component 2311; the installation position of the first pneumatic lifting magnet assembly 32 corresponds to the installation position of the magnetic switch, and the first pneumatic lifting magnet assembly 32 is located above the magnetic switch, and the first pneumatic lifting magnet assembly 32 is used to trigger the magnetic switch to open the magnetism of the magnetic pressure head 231.

[0069] Optionally, the first pneumatic lifting magnet assembly 32 includes a first mounting plate 321, a second cylinder 323, and a first lifting shaft 322; the first lifting shaft 322 is mounted on the first mounting plate 321; the mounting position of the first lifting shaft 322 corresponds to the mounting position of the magnetic switch; the second cylinder 323 is connected to the first lifting shaft 322, and the second cylinder 323 is used to drive the first lifting shaft 322 to rise and fall, so that the magnetic switch is triggered by the first lifting shaft 322 to activate the magnetism of the magnetic pressure head 231, thereby connecting the electromagnet 31 and the magnetic pressure head 231 by magnetic adsorption.

[0070] In this embodiment, the second cylinder 323 is first activated, driving the first top shaft 322 to extend downwards until it reaches the magnetic switch mounted on the support base plate 21. This triggers the magnetic switch, activating the magnetism of the magnetic pressure head 231. The electromagnet 31 then contacts the magnetic component 2311, attracting it via magnetic adsorption. At this point, the adjustment component 33 controls the lifting of the electromagnet 31 and the magnetic pressure head 231. Next, the OLED product is placed on the double-sided pressing fixture 2 and alignment compensation is performed. After alignment, the magnetic pressure head 231 is pressed down, and the magnetic switch disconnects the magnetism of the magnetic component 2311, breaking the magnetic adsorption between the electromagnet 31 and the magnetic component 2311. This allows the magnetic pressure head 231 to perform B-side pressing on the OLED product below. In this embodiment, the pressing of the OLED product is completed using a mechanical on / off magnetic adsorption pressing method, facilitating the movement and handling of the double-sided pressing fixture 2.

[0071] Optionally, the fixture support plate device 1 includes a fixture support plate 11 and a second pneumatic lifting magnet assembly 12; the second pneumatic lifting magnet assembly 12 is mounted on the fixture support plate 11; the mounting position of the second pneumatic lifting magnet assembly 12 corresponds to the mounting position of the magnetic switch, and the second pneumatic lifting magnet assembly 12 is located below the magnetic switch, and the second pneumatic lifting magnet assembly 12 is used to trigger the magnetic switch to close the magnetism of the magnetic pressure head 231.

[0072] In this embodiment, the second pneumatic lifting magnet assembly 12 includes a second top shaft, a third cylinder, and a second mounting plate. The mounting position of the second top shaft corresponds to the mounting position of the magnetic switch, and the second top shaft is located below the magnetic switch. The second top shaft is mounted on the second mounting plate and connected to the third cylinder.

[0073] In this embodiment, after the B-side OLED product alignment is completed and the magnetic pressure head 231 is pressed down, the third cylinder operates, driving the second top axis to extend upwards until it reaches the magnetic switch on the supporting base plate 21. This triggers the magnetic switch to deactivate the magnetism of the magnetic pressure head 231, eliminating magnetic attraction between the electromagnet 31 and the magnetic component 2311. The magnetic component 2311 detaches from the electromagnet 31, and the magnetic pressure head 231 presses down due to gravity, achieving the B-side pressing and fixing of the OLED screen. Thus, the B-side pressing of the OLED product is completed through a mechanical on / off magnetic adsorption pressing method, facilitating the movement and handling of the double-sided pressing fixture 2.

[0074] Optionally, the fixture support tray device 1 further includes a fixture support platform 13 and a pneumatic clamping and positioning assembly 14; both the fixture support platform 13 and the pneumatic clamping and positioning assembly 14 are mounted on the fixture support tray 11. The fixture support platform 13 is used to support the double-sided crimping fixture 2, and the pneumatic clamping and positioning assembly 14 is used to position and clamp the double-sided crimping fixture 2. The pneumatic clamping and positioning assembly 14 may include a jaw and a first cylinder; the jaw and the first cylinder are connected, and both are mounted on the fixture support tray 11. After the double-sided crimping fixture 2 is placed on the fixture support platform 13, the jaw is controlled by the first cylinder to clamp and fix the double-sided crimping fixture 2.

[0075] In this embodiment, the fixture support plate 11 is a hollow plate so as not to obstruct the optical alignment mechanism 4 below from visually aligning the OLED product above. Furthermore, a fixture support platform 13 and a pneumatic clamping and positioning assembly 14 are respectively provided around the fixture support plate 11 so that the double-sided pressing fixture 2 can be placed on the fixture support platform 13 and clamped and fixed by the pneumatic clamping and positioning assembly 14, thereby improving the stability of the double-sided pressing fixture 2 on the fixture support platform 13.

[0076] Optionally, the adjustment assembly 33 includes a UVW alignment platform 331 and a Z-axis precision micro-motion platform 332; the UVW alignment platform 331 is mounted on the jig support plate device 1 and is located outside the magnet adsorption pressing assembly 23; the UVW alignment platform 331 is connected to the Z-axis precision micro-motion platform 332; the Z-axis precision micro-motion platform 332 is connected to the first pneumatic lifting magnet assembly 32.

[0077] In this embodiment, the UVW alignment platform 331 and the Z-axis precision micro-motion platform 332 cooperate to jointly control the first pneumatic lifting magnet assembly 32 for alignment adjustment. This allows for alignment compensation of the magnet adsorption pressing assembly 23 in the X, Y, and θ directions when the electromagnet 31 of the first pneumatic lifting magnet assembly 32 adsorbs the magnetic pressure head 231, achieving precise alignment. It should be noted that the structure and working principle of the UVW alignment platform 331 and the Z-axis precision micro-motion platform 332 are existing technologies and will not be described in detail here. In one possible embodiment, the multi-axis automatic adjustment mechanism 3 also includes a movable bracket 34.

The camera lens 41 is used for visual alignment of the OLED product, and the lens clamping fixture 42 is used to fix and clamp the camera lens 41. The motor module 44 is connected to the lens fine-tuning component 43 and is used to drive the lens fine-tuning component 43 to move through the motor module 44, thereby driving the camera lens 41 to perform position fine-tuning.

[0079] In this embodiment, the camera lens 41 is fixed by the lens clamping fixture 42 and connected to the lens fine-tuning component 43. The camera lens 41 is used for visual alignment of the OLED product and the double-sided pressing fixture 2. The lens fine-tuning component 43 can achieve fine-tuning of the vertical movement of the camera lens 41. Specifically, the lens fine-tuning component 43 has a telescopic mechanism inside. The lens fine-tuning component 43 can be driven by a cylinder or by the motor module 44 to achieve vertical extension and retraction, thereby realizing the vertical movement fine-tuning of the camera lens 41. In addition, the left and right movement adjustment of the camera lens 41 can also be achieved by connecting the motor module 44 to the lens fine-tuning component 43. Specifically, the motor module 44 may include a motor support plate, a motor, and a slide rail. The slide rail and the motor are mounted on the motor support plate, and the lower end of the lens fine-tuning component 43 is connected to the slide rail and the motor respectively. When the motor is working, it drives the lens fine-tuning component 43 to move left and right on the slide rail, thereby realizing the left and right movement adjustment of the camera lens 41. In one possible embodiment, the camera lens 41 is rotatably connected to the lens fine-tuning component 43, so that the camera lens 41 can rotate on the lens fine-tuning component 43 to achieve fine-tuning of the camera lens 41 in all directions, facilitating multi-angle visual alignment.

[0080] Based on the embodiments described above, the working principle of the double-sided crimping device provided in this application includes: First, an unloaded double-sided crimping fixture 2 is moved onto the fixture support platform 13 of the fixture support tray device 1. The first cylinder of the pneumatic clamping and positioning assembly 14 controls the grippers to clamp and fix the support base plate 21 of the double-sided crimping fixture 2. At this time, the UVW alignment platform 331 and the Z-axis precision micro-motion platform 332 drive the first pneumatic lifting magnet assembly 32 and the electromagnet 31 to press down. The first top shaft 322 of the first pneumatic lifting magnet assembly 32 contacts the magnetic switch. The magnetic switch activates the magnetism of the magnetic component 2311. The electromagnet 31 contacts the magnetic component 2311 and generates magnetic attraction, thereby fixing the magnetic pressure head 231 and the electromagnet 31. Then, the UVW alignment platform 331 and the Z-axis precision micro-motion platform 332 drive the electromagnet 31 and the magnetic pressure head 231 to rise. Then, a robotic arm moves the OLED product above the double-sided pressing fixture 2. An optical alignment mechanism 4 aligns edge A of the OLED product with the fixed pressing head 22, and the robotic arm performs X, Y, and θ direction compensation adjustments based on this alignment result. After successful alignment compensation, the robotic arm places the OLED product on the support base plate 21 of the double-sided pressing fixture 2, and the fixed pressing head 22 performs a pressing action on edge A of the OLED product. Next, the optical alignment mechanism 4 aligns edge B of the OLED product with the magnetic pressing head 231, and the UVW alignment platform 331 and Z-axis precision micro-motion platform 332 perform X, Y, and θ direction compensation. After successful alignment compensation, the UVW alignment platform 331 and Z-axis precision micro-motion platform 332 drive the magnetic pressing head 231 to press down. At this time, the second top shaft of the second pneumatic lifting magnet assembly 12 on the fixture support plate device 1 contacts the magnetic switch, triggering the magnetic switch to close the magnetism of the magnetic component 2311 on the magnetic pressure head 231, thereby disconnecting the magnetic attraction between the electromagnet 31 and the magnetic component 2311, so that the magnetic pressure head 231 disengages from the electromagnet 31 and presses down by its own gravity to complete the B-side pressing of the OLED product. The electromagnet 31 and the first pneumatic lifting magnet assembly 32 rise, completing the double-sided pressing of the OLED product, realizing double-sided pressing. Then, the double-sided pressing fixture 2 and the OLED product that have completed pressing can be moved and transported to the aging equipment for aging test by a robot, realizing automated operation.
