Description

Technical Field

[0001] This invention relates to the field of panel aging process technology, and in particular to an aging testing device and method for vehicle-mounted flat panel displays. Background Technology

[0002] In the field of flexible and rigid OLED panel aging technology, automotive flat panel displays, as an important application carrier, require pre-shipment aging testing as a crucial step to ensure product reliability. Currently, most OLED panel aging processes in the industry employ furnace-type aging equipment. The typical process involves placing the OLED panel to be tested into a customized fixture, using a robotic arm to transfer the fixture containing the panel into the furnace, then performing the panel-to-test circuit connection operation, followed by aging tests such as high temperature, high pressure, or long-term illumination.

[0003] However, existing furnace-type aging equipment has significant limitations in practical applications: Firstly, the equipment has poor product compatibility. Because the fixtures and furnace structures are mostly designed with fixed dimensions, they can only accommodate specific OLED panel sizes. When testing products of different sizes (especially the various sizes within the 6-15 inch range commonly seen in automotive applications), the entire fixture and corresponding furnace adapter components must be replaced. This is not only cumbersome but also leads to extended equipment downtime, severely impacting production line continuity. Secondly, the switching efficiency is low. Limited by the internal space layout of the furnace and the single-batch loading capacity, existing equipment cannot achieve parallel aging testing of multiple product groups. Furthermore, during product changeovers, manual intervention is required for fixture adjustments and parameter calibration, increasing on-site manpower demands and further reducing production line efficiency.

[0004] The above problems are even more prominent in the aging test scenario of automotive flat panel displays—automotive products have diverse sizes and frequent batch changes, and the rigid structure and inefficient replacement mode of existing equipment can no longer meet the needs of flexible production. Summary of the Invention

[0005] To address all or part of the problems in the prior art, this invention provides an aging test device and method for vehicle-mounted flat panel displays. Through a symmetrical and compact flow layout, multi-unit and multi-station design, and fully automated transfer throughout the process, it achieves efficient parallel aging test of products of different sizes, improves equipment compatibility, testing capacity and automation level, and reduces labor costs and downtime risks.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An aging test device for vehicle-mounted flat panel displays includes:

[0008] The feeding mechanism is used to receive the product to be tested.

[0009] An aging mechanism is used to perform aging tests on the product to be tested. The aging mechanism includes at least two sets of parallel aging units. Each set of aging units has multiple aging positions arranged along a first direction for carrying and performing aging tests. The aging positions can hold products of different sizes to be tested.

[0010] The discharge mechanism is used to output the product that has completed the aging test; the feeding mechanism and the discharge mechanism are arranged sequentially along the first direction and are located on the same side of the aging mechanism;

[0012] A first pick-and-place device is provided between the feeding mechanism and the aging mechanism, and a second pick-and-place device is provided on the side of the aging mechanism away from the feeding mechanism.

[0013] Both the first and second transport mechanisms include a linear guide rail, a correction component, and a platform. The correction component is mounted on the linear guide rail via a slider, and the platform is mounted on the correction component. The correction component is configured to adjust the position of the platform in at least one direction.

[0014] The stage includes an adsorption platform body, a transparent platform, and a front adsorption platform arranged in sequence. The adsorption platform body is used to fix the product to be tested. The transparent platform is made of light-transmitting material. The front adsorption platform is provided with multiple adsorption holes for auxiliary adsorption and fixation of the front end area of ​​the product to be tested.

[0015] Each aging unit includes a support platform, multiple aging stations, and a transfer device. The multiple aging stations are arranged along the length of the support platform. The transfer device is slidably mounted on a guide rail on the side of the support platform via a mounting bracket and can move back and forth between the multiple aging stations along the guide rail.

[0016] Each of the aging stations includes a pressing platform and a pressing device. The pressing platform is used to adsorb and fix the product to be tested. The pressing device is set in relation to the pressing platform and can move toward the pressing platform to electrically connect with the product placed on the pressing platform and perform a lighting operation.

[0017] The transfer device includes a square frame, two first slide rails, two second slide rails, and multiple cameras. The two first slide rails are respectively arranged on both sides of the square frame perpendicular to the length direction of the support platform. The two ends of the two second slide rails are respectively slidably arranged on the first slide rails. The multiple cameras are slidably arranged on the second slide rails for photographing the crimping points of the product under test.

[0018] An appearance inspection mechanism is also provided between the discharge mechanism and the second transport mechanism. The appearance inspection mechanism includes an appearance inspection station and a manual inspection station.

[0019] The first pick-and-place device is used to transfer the product to be tested between the feeding mechanism and the first transport mechanism or the second transport mechanism, and to transfer the product to be tested between the first transport mechanism or the second transport mechanism and a group of aging units; the second pick-and-place device is used to transfer the product to be tested between the first transport mechanism or the second transport mechanism and another group of aging units.

[0025] S5. Discharge: The first pick-and-place device transfers the inspected product from the second transport mechanism to the discharge mechanism, where it is output.

[0026] Between steps S4 and S5, there is also a visual inspection step: the visual inspection agency performs visual defect inspection on the products that have completed the aging test, and the products that pass the visual inspection are transferred to the discharge mechanism by the second transport mechanism; the products that fail the visual inspection are transferred to the manual inspection station by the second transport mechanism for re-inspection, and after passing the re-inspection, they are transferred to the discharge mechanism.

[0037] The technical solutions in specific embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0038] This invention discloses an aging test device for in-vehicle flat panel displays, aiming to achieve efficient aging test and automated workflow for in-vehicle flat panel displays, improving test accuracy and equipment adaptability. (Refer to the references...) Figures 1 to 8 As shown, the specific structure of the equipment is as follows: The equipment adopts a modular layout design, mainly including a feeding mechanism 1, an aging mechanism 2, an unloading mechanism 3, a first transport mechanism 4, a second transport mechanism 5, and multiple sets of pick-and-place devices. These mechanisms work together to complete the fully automated aging test process for the products under test. The feeding mechanism 1 serves as the initial receiving unit for the products under test. It can receive externally transported vehicle-mounted flat panel displays via a conveyor belt or tray structure. Its feeding end connects to the upstream production line to ensure continuous product supply. The aging mechanism 2 is the core testing unit of the equipment, used for long-term illumination aging tests on the products under test. This mechanism includes at least two sets of aging units arranged parallel to each other along the X-axis. Each set of aging units has multiple aging stations 202 arranged sequentially along the X-axis, significantly improving testing efficiency through parallel operation of multiple stations. The unloading mechanism 3 outputs the products that have completed the aging test, and its unloading end can connect to the downstream production line. The feeding mechanism 1 and the unloading mechanism 3 are arranged sequentially along the X-axis and are located on the same side of the aging mechanism 2 (defined as the front side of the equipment). The first transport mechanism 4 and the second transport mechanism 5 are respectively located on the left and right sides of the aging mechanism 2, undertaking the function of transferring products between various processes. Specifically, the first transport mechanism 4 is responsible for transferring products to be tested between the feeding mechanism 1 and the aging mechanism 2, while the second transport mechanism 5 is responsible for transferring products that have completed testing between the aging mechanism 2 and the discharging mechanism 3. These two mechanisms form a symmetrical transport structure, ensuring optimal product flow paths. Multiple sets of pick-and-place devices are respectively configured between the feeding mechanism 1 and the first transport mechanism 4, between the first transport mechanism 4 and the aging mechanism 2, between the aging mechanism 2 and the second transport mechanism 5, and between the second transport mechanism 5 and the discharging mechanism 3, achieving product transfer between the mechanisms through precise gripping and placement actions.

[0039] Specifically, both the first transport mechanism 4 and the second transport mechanism 5 adopt the same modular design, both including a linear guide rail, a correction component, and a platform. The correction component is mounted on the linear guide rail via a slider, and the platform is mounted on the correction component. The correction component is configured to adjust the position of the platform in at least one direction to eliminate positional deviations of the product during transport. In this embodiment, the linear guide rail is arranged along the Y-axis, and the correction component includes an X-axis drive structure and a θ-axis drive structure. The X-axis drive structure is fixedly mounted on the slider and can drive the θ-axis drive structure to translate along the X-axis direction. The θ-axis drive structure is located at the drive end of the X-axis drive structure and can drive the platform to rotate around the Z-axis (θ-direction adjustment). The platform is mounted at the drive end of the θ-axis drive structure. Through the coordinated adjustment of the X-axis and θ-axis, the platform can achieve positional compensation at the ±0.1mm level, ensuring precise docking of the product with subsequent mechanisms.

[0040] The stage comprises a main adsorption platform, a transparent platform, and a front adsorption platform arranged sequentially. The main adsorption platform has an array of vacuum adsorption holes on its surface, used to fix the main body of the product under test using negative pressure, ensuring stable placement. The transparent platform is made of a high-transmittance material (such as optical-grade acrylic or tempered glass), facilitating reading the product from below and meeting the requirements for top-to-bottom reading. The front adsorption platform has multiple adsorption holes for auxiliary adsorption and fixation of the front end area of ​​the product under test, ensuring flatness and reducing the impact of product warping on image acquisition. This stage meets the requirements for vertical image alignment, improving equipment yield, and is compatible with both vertical and horizontal reading operations. When the product is placed on the stage, the transparent platform provides a convenient optical path for reading the code from below.

[0041] Each aging unit operates independently and can process multiple products in parallel. Each unit includes a support platform 201, multiple aging stations 202, and a transfer device 203. The multiple aging stations 202 are arranged along the length (X-axis) of the support platform 201. The transfer device 203 is slidably mounted on a guide rail on the side of the support platform 201 (along the X-axis) via a mounting bracket, allowing it to move back and forth between the multiple aging stations 202 along the guide rail. The support platform 201 adopts a combination structure of a steel frame and a marble tabletop, possessing high strength and high stability. The bottom of the support platform 201 is also equipped with a vibration damping structure, which consists of vibration damping pads or spring assemblies (such as rubber vibration damping pads or spring dampers), reducing vibration transmission during equipment operation and ensuring testing accuracy. Each aging station 202 includes a pressing platform and a pressing device. The surface of the pressing platform has vacuum adsorption holes for placing and fixing products of different sizes to be tested. The crimping device is set up to correspond to the crimping platform and consists of a drive component and a probe module. It can move along the Z-axis towards the crimping platform: when descending, the probe module precisely aligns with the electrode interface of the product to achieve electrical connection and perform lighting operation; when ascending, the probe separates from the product, making it easy to pick up and put down the product.

[0042] The transfer device 203 includes a square frame 2031, two first slide rails 2032, two second slide rails 2033, and multiple sets of vision units. The square frame 2031 is constructed from aluminum alloy profiles, providing a mounting base for all components. The two first slide rails 2032 are respectively arranged parallel to each other on both sides of the square frame 2031, perpendicular to the length direction (Y-axis direction) of the support platform 201. Each first slide rail 2032 has at least two sliders, and each side is equipped with a driver (such as a servo motor) to move the corresponding slider. The two second slide rails 2033 are arranged along the X-axis direction, with their ends fixed to the sliders of the two first slide rails 2032, and can move along the first slide rails 2032 (Y-axis direction) driven by the drivers. Multiple sets of vision units are mounted on the second slide rails 2033 via sliders, with at least two sets of vision units on each second slide rail 2033, and can move along the X-axis direction with the sliders. One vision unit on the second slide rail 2033 corresponds to the crimping point on one side of the old work station 202, and the other vision unit on the second slide rail 2033 corresponds to the crimping point on the other side of the old work station 202. Real-time images of the crimping position can be captured and fed back to the control system, enabling online monitoring of crimping accuracy. Each vision unit group includes two cameras 2034 to improve the comprehensiveness and accuracy of image acquisition. The crimping platform can accommodate single, double, or quadruple products of different sizes. The spacing between multiple vision units can be adjusted via the slider of the second slide rail 2033. The appropriate vision unit combination can be selected for alignment detection based on the number and arrangement of products on the crimping platform, allowing for flexible switching of detection adaptability. An air knife is also installed on the square frame 2031, with its outlet facing the crimping area of ​​the old work station 202. High-speed airflow removes dust and impurities from the crimping surface, preventing poor contact and ensuring crimping stability.

[0043] A visual inspection mechanism is also provided between the unloading mechanism 3 and the second transport mechanism 5. This mechanism includes a visual inspection station 8 and a manual inspection station 9. The visual inspection station 8 is arranged in the same row as the infeed mechanism 1 and the unloading mechanism 3. It is equipped with a positioning camera 2034 and a light source system to take pictures for visual inspection. Products that pass inspection are transported to the unloading mechanism 3, while unqualified products are transferred to the manual inspection station 9 for re-inspection by humans to ensure the accuracy of defect identification.

[0044] A first pick-and-place device 6 is provided between the feeding mechanism 1 and the aging mechanism 2, and a second pick-and-place device 7 is provided on the side of the aging mechanism 2 away from the feeding mechanism 1. The first pick-and-place device 6 is used to transfer the product to be tested between the feeding mechanism 1 and the first transport mechanism 4 or the second transport mechanism 5, and to transfer the product to be tested between the first transport mechanism 4 or the second transport mechanism 5 and a set of aging units. The second pick-and-place device 7 is used to transfer the product to be tested between the first transport mechanism 4 or the second transport mechanism 5 and another set of aging units. Dust removal devices are also provided on both sides of the first pick-and-place device 6, corresponding to the positions of the first transport mechanism 4 and the second transport mechanism 5, for dust removal of the products on the first transport mechanism 4 and the second transport mechanism 5. Each pick-and-place device includes a frame arranged horizontally, specifically along the X-axis in this embodiment. The frame is made of aluminum alloy profiles combined with linear guide rails to provide a moving track for the robotic arms. At least two sets of robotic arms are slidably mounted on the frame via sliders, and can move independently along the X-axis. Loading and unloading can be performed simultaneously, reducing waiting time. Each robotic arm assembly includes an adjustment component and a suction component. The adjustment component is mounted on a guide rail of the frame via a slider, and the suction component is mounted on the moving end of the adjustment component. The adjustment component is configured to adjust the position of the suction component in at least one direction. The adjustment component includes a Y-axis drive module (translation adjustment), a Z-axis drive module (lifting adjustment), and a θ-axis drive module (rotation adjustment) connected in sequence, enabling posture adjustment in three-dimensional space. The suction component is mounted on the drive end of the θ-axis drive module via a quick-change structure, facilitating rapid replacement of suction cups of different sizes (adapted to product dimensions). The suction component includes multiple sets of position-adjustable suction cups, using negative pressure to suction the product and avoid clamping damage.

[0045] This invention also provides an aging test method for in-vehicle flat panel displays, implemented based on the aforementioned in-vehicle flat panel display aging test equipment, comprising the following steps:

[0046] S1. Feeding: The feeding mechanism 1 receives a tray containing the product to be tested from the upstream production line via a conveyor belt or pallet structure. Its feeding end is precisely connected to the upstream production line to ensure continuous product supply. After positioning the tray, the feeding mechanism 1 identifies the tray code and the initial position of the product to be tested within the tray using a barcode reader, providing a positional reference for subsequent pick-and-place operations.

[0047] S2. Feeding and Transfer: The first pick-and-place device 6 is activated. Its robotic arm, through the coordinated adjustment of the Y-axis, Z-axis, and θ-axis drive modules, utilizes multiple adjustable suction cups from the feed tray of the feeding mechanism 1 to precisely pick up the product to be tested. The first pick-and-place device 6 places the product to be tested onto the platform of the first transport mechanism 4. The platform's adsorption platform body uses an array of vacuum adsorption holes to apply negative pressure to the main body area of ​​the product. The front adsorption platform assists in adsorption of the front end area of ​​the product through adsorption holes, ensuring the product is flat and fixed (reducing the impact of warping). The transparent platform reserves an optical path for subsequent upper and lower code reading. Dust removal devices on both sides of the first pick-and-place device 6 remove dust from the product to be tested on the first transport mechanism 4 to prevent dust from affecting subsequent testing accuracy. The first transport mechanism 4 uses a linear guide rail (along the Y-axis) to move the platform towards the aging mechanism 2, and uses a correction component to perform position compensation, eliminating positional deviations during transport and ensuring precise docking between the product and the aging mechanism 2. Finally, the platform transfers the product to the feeding side of the aging mechanism 2.

[0048] S3. Aging Test: Depending on the idle status of the two aging units in aging mechanism 2, the first pick-and-place device 6 (for transfer between the first transport mechanism 4 and the first aging unit) or the second pick-and-place device 7 (for transfer between the first transport mechanism 4 and the second aging unit) transfers the product to be tested from the platform of the first transport mechanism 4 to the pressing platform of the corresponding aging unit. The pressing platform fixes the product to be tested through vacuum adsorption holes on its surface. At the same time, the transfer device 203 moves to the corresponding aging position 202, and the air knife on it blows high-speed airflow into the pressing area to remove dust and impurities from the pressing surface and avoid poor contact. The drive component of the pressing device drives the probe module to descend along the Z-axis. The transfer device 203 captures the pressing position image in real time and feeds it back to the control system, so that the probe and the electrode interface of the product are precisely aligned, realize electrical connection, and start the lighting operation to begin the aging test of the preset duration.

[0049] S4. Material Transfer: After the aging test is completed, the probe module of the crimping device rises along the Z-axis and separates from the product. The first pick-and-place device 6 or the second pick-and-place device 7 operates again, transferring the tested product from the aging station 202 to the platform of the second transport mechanism 5. The second transport mechanism 5 transfers the product along the Y-axis to the appearance inspection mechanism. The alignment camera 2034 and light source system at the appearance inspection station 8 photograph the product to complete the appearance defect detection (such as scratches, display abnormalities, etc.). Products that pass the inspection are transferred by the second transport mechanism 5 to the feeding side of the discharge mechanism 3. Products that fail the inspection are transferred by the second transport mechanism 5 to the manual inspection station 9 for manual re-inspection. Products that pass the re-inspection are returned to the second transport mechanism 5 and transferred to the discharge mechanism 3, while products that fail the inspection are temporarily stored in the defective product box at the manual inspection station 9.

[0050] S5. Discharge: The robotic arm of the first pick-and-place device 6 picks up the inspected products from the platform of the second transport mechanism 5 and transfers them to the conveyor belt or pallet of the discharge mechanism 3. The discharge end of the discharge mechanism 3 connects with the downstream production line to output the products to the next process, completing the entire aging test process.

[0051] This invention, through the design of multiple parallel aging units and an aging station 202 adaptable to products of different sizes, overcomes the limitations of traditional fixed fixtures and furnaces on product specifications, significantly improving the equipment's compatibility with various automotive flat panel displays ranging from 6 to 15 inches. Aging testing of products of different sizes can be achieved without frequent fixture changes. The multi-station parallel aging mode and automated transfer device 203, combined with the synchronous loading and unloading function of the pick-and-place device, significantly increase the single-batch testing volume and cutting efficiency, reducing equipment downtime. Through the use of correction components and vision units, precise positioning and automated transfer are achieved throughout the entire process. Combined with the automatic screening and manual re-inspection mode of the appearance inspection mechanism, manual fixture adjustments and parameter calibration are reduced, lowering the customer's on-site manpower requirements and ultimately improving the overall production line efficiency, meeting the flexible production needs of automotive flat panel displays.

[0052] It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
