Description

Technical Field

[0001] The present invention relates to the technical field of display testing, in particular to a feeding device for a visually guided display testing line. Background Art

[0002] A monitor is a computer's I / O device, or output device. It's a display tool that displays electronic files on the screen via a specific transmission device. Monitor testing primarily evaluates and verifies monitor performance in different environments, ensuring compliance with design specifications, usage requirements, or industry standards.

[0003] For example, publication number CN118373132A discloses a display screen inspection machine and an operating method. The inspection machine includes a display screen feeding mechanism, a display screen cleaning mechanism, a display screen inspection mechanism and a display screen unloading mechanism, which are connected in sequence; the display screen inspection mechanism includes a rotary feeding and unloading device for quickly feeding and unloading the display screen, a clamping adjustment device, an upper CCD camera device, a lower CCD auxiliary alignment device, an inspection frame, a precision positioning device, a transfer device and a handling and unloading transfer device; the rotary feeding and unloading device includes a rotating disk and a rotating drive motor; the rotating disk has multiple rotating stations, and multiple discharge stations are arranged side by side on each rotating station.

[0004] However, in the existing technology, the feeding link in the display testing process lacks a real-time posture monitoring function, resulting in the inability to dynamically collect the workpiece's posture data during the grasping process. If an offset or tilt occurs, the system cannot be adjusted in time, which in turn affects the accuracy of subsequent placement. Traditional manual visual inspection or fixed-angle camera detection methods have difficulty identifying minor defects and have a high missed detection rate, which can easily lead to defective products flowing into the next process. In addition, the fixed-installed camera has a limited monitoring angle and cannot achieve a full-range scan of the workpiece. There are visual blind spots, which can easily cause defective products to be mistakenly put into the testing process. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a conveyor belt is used to stably transport the display screen to the suction position under the robotic arm. After the display screen is stationary, the robotic arm completes precise grasping through the suction cup. In order to deal with the skew and offset problems that may occur during the conveying process, a monitoring camera installed on the guide mechanism is equipped to collect position deviations in real time and identify surface defects of the display screen to prevent abnormal products from entering the subsequent process. During the identification process, the position and viewing angle of the camera are dynamically changed by driving the rotating rod to link the gear and the arc rack, thereby realizing posture monitoring in a wider range.

[0017] 2. In the present invention, the driving rod is driven to rotate by energizing the reduction motor, and then the two second transmission rods are synchronously driven to achieve angle adjustment or linear movement. The power is then transmitted to the first transmission rod and the mounting rod through the first connecting rod, prompting the mounting rod and the second mounting frame to work together to complete the camera angle adjustment. During this process, the third transmission rod plays a coordinating and restraining role to prevent component offset or asynchrony. At the same time, the second sliding block moves smoothly under the guidance of the arc track, ensuring that the camera adjustment is accurate and correct, and ultimately achieving the matching of the camera angle and the operating area of ​​the robotic arm, thereby improving the intelligence and accuracy of the display screen capture and transfer operations.

[0018] 3. In the present invention, the conveyor belt is controlled by the conveying module to achieve stable transportation of the display screen, and multiple conveyor belts are supported to run in parallel to meet different testing requirements.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1-Figure 5 The figure shows a feeding device for a visually guided display test line, comprising a conveyor belt 1 and two mobile platforms 3 mounted at the bottom of one side thereof, a mobile plate 31 fixedly connected to the top of the mobile platform 3, a robotic arm 2 for transferring display components mounted on one side of the top of the mobile plate 31, a transposition mechanism 4 mounted on one side of the top of the mobile platform 3, an adjustment mechanism 5 connected to the top of the transposition mechanism 4, a guide mechanism 6 connected to the inside of the adjustment mechanism 5, the transposition mechanism 4 being used to adjust the orientation of the adjustment mechanism 5 and the guide mechanism 6, and the device also comprising a visual guidance system for coordinating the adjustment mechanism 5, the guide mechanism 6, and the robotic arm 2; The adjustment mechanism 5 includes a support frame 52, one end of which is fixedly connected to a second slide rail 53. A rotating rod 54 is rotatably connected to the inner side of the support frame 52. A gear 55 is fixedly connected to the outer surface of the rotating rod 54. An arc-shaped plate 57 is slidably connected to the inner side of the second slide rail 53. The side wall of the arc-shaped plate 57 is fixedly connected to an arc-shaped rack 56 that meshes with the gear 55. The guiding mechanism 6 includes a first mounting frame 61 and a fixed rod 63 fixedly connected to one end of the first mounting frame, a curved track 631 fixedly connected to one end of the fixed rod 63, a second sliding block 64 slidingly connected to the inner side of the curved track 631, a second mounting frame 65 fixedly connected to one end of the second sliding block 64, and a mounting rod 67 fixedly connected to the inner side of the second sliding block 64, a monitoring camera 66 is installed on the side wall of the second mounting frame 65, a driving assembly is transmission-connected to one side of the first mounting frame 61, and the driving assembly is transmission-connected to the second mounting frame 65.

[0023] In this embodiment, conveyor belt 1 ensures stable transport of display components. Once the display components reach the designated pickup position beneath robotic arm 2, conveyor belt 1 stops, ensuring the display remains stationary for subsequent grasping operations. At this point, robotic arm 2 precisely grasps the display by controlling the suction cup attached to its end. However, during the conveying process, the display may become skewed or misaligned due to factors such as friction, inertia, or interference between components.

[0024] A monitoring camera 66, mounted on the guide mechanism 6, is equipped to monitor the display screen's posture and status from multiple angles and in all directions. This camera not only captures real-time information on the display screen's positional deviations, ensuring accurate suction cup alignment during the gripping process to prevent issues like drift and falling, but also provides preliminary identification of abnormalities such as cracks or damage on the display screen. If damage is detected, a signal is generated, preventing the robotic arm 2 from transferring the defective product to subsequent testing equipment, effectively reducing testing costs and the risk of equipment malfunction.

[0025] During the monitoring and recognition process, the rotating rod 54, powered by the rotational force provided by the drive assembly, begins to rotate, driving the connected gear 55 to rotate synchronously. Gear 55 then engages with the curved rack 56, exerting a driving force to move it along a predetermined trajectory. The movement of the curved rack 56 deflects the curved plate 57 connected to it, thereby dynamically changing the position and viewing angle of the surveillance camera 66 mounted on the curved plate 57. This significantly expands the camera's field of view, enabling effective recognition of a wider range of display screen angles.

[0026] Furthermore, a second mounting bracket 65 and its associated sliding structure are provided. Driven by a drive assembly, the second mounting bracket 65 can achieve horizontal curved displacement. A second sliding block 64 is mounted within a curved track 631 and can slide smoothly along it, enabling fine adjustment of the monitoring camera 66 between different angles. This not only enhances the camera's real-time monitoring of the suction position but also allows continued monitoring of the working area below the display after the display is captured, ensuring safe and reliable subsequent handling and placement.

[0027] Example 2: Figure 5 As shown, the drive assembly includes a drive rod 621, one end of which is rotatably connected to the first mounting bracket 61. Second transmission rods 681 are rotatably connected to both sides of one end of the drive rod 621. One end of each of the two second transmission rods 681 is rotatably connected to the first connecting rod 68. The outer surfaces of the two first connecting rods 68 are rotatably connected to the first transmission rod 671. One end of each of the two first transmission rods 671 is rotatably connected to the outer surface of the mounting rod 67. A reduction motor 62 is mounted on the side wall of the first mounting bracket 61. The output end of the reduction motor 62 is fixedly connected to one end of the drive rod 621. A second connecting rod 69 is fixedly connected to the side wall of one end of the first mounting bracket 61. Two third transmission rods 682 are rotatably connected to the outer surface of the second connecting rod 69. One end of the two third transmission rods 682 is rotatably connected to the two first connecting rods 68, respectively.

[0028] In this embodiment, during the process of adjusting the angle of the surveillance camera 66, after the reduction motor 62 is powered on, its output shaft drives the driving rod 621 to rotate. The driving rod 621 serves as the first transmission link, and its rotational power will be synchronously transmitted to the two second transmission rods 681 arranged on both sides thereof, prompting the two second transmission rods 681 to synchronously adjust the angle and move linearly.

[0029] Then, the two second transmission rods 681 distribute and transmit the transmission force to the two first transmission rods 671 through their respective connected first connecting rods 68. After receiving the transmission force, the two first transmission rods 671 respectively transmit the force to the installation rod 67, causing the installation rod 67 to move in a predetermined direction.

[0030] The movement of mounting rod 67 further drives the synchronous movement of the connected second mounting bracket 65, completing the angle adjustment of the camera mounting assembly. During this process, the coordinated movement of the two first connecting rods 68 not only distributes the transmission force but also, with the cooperation of the third transmission rod 682, ensures stable linkage of the entire mechanism. The third transmission rod 682 primarily serves as a coordination and constraint, preventing deviation or asynchrony between components during movement.

[0031] Simultaneously, as the second mounting bracket 65 moves, the second slider 64 to which it is attached also moves. The movement of the second slider 64 is precisely limited by the curved track 631 provided on the base, ensuring smooth movement along the pre-set curved path and avoiding instabilities such as shaking and drifting. Ultimately, through the coordinated operation of these components, the angle of the surveillance camera 66 can be precisely adjusted to ensure that the camera's viewing angle matches the operating area of ​​the robotic arm 2, effectively guiding the robotic arm 2 to grasp and transfer the display screen, enhancing the overall system's intelligence and operational precision.

[0032] Example 3: According to Figure 6 and Figure 7As shown, the shifting mechanism 4 includes a first slide rail 42, a slide groove 421 being defined in the middle of the first slide rail 42, a first sliding block 43 being slidably connected to the inner side of the slide groove 421, a center block 442 being fixedly connected to the top center of the first sliding block 43, a first rotating block 44 being rotatably connected to the outer surface of the center block 442, a touch plate 441 being fixedly connected to the outer surface of the first rotating block 44, and two limiting rods 431 being symmetrically fixedly connected to one side of the top of the first sliding block 43. A connector 482 is rotatably connected to the inner side of one end of the first rotating block 44, a movable rod 48 being fixedly connected to one end of the connector 482, a second rotating block 47 being slidably connected to the outer surface of one end of the movable rod 48, and the bottom end of the second rotating block 47 is rotatably connected to the top of the first sliding block 43. A spring 481 is provided between the connector 482 and the second rotating block 47. The spring 481 is sleeved on the outer surface of the movable rod 48. A connecting block 49 is fixedly connected to the center of the bottom of the first sliding block 43. The connecting block 49 is slidably connected to the first slide rail 42. The bottom of the connecting block 49 is fixedly connected to the first connecting frame 41. The bottom of the first connecting frame 41 is fixedly connected to the top of the movable plate 31. The tops of both ends of the first slide rail 42 are fixedly connected to the limit blocks 422. The top of the first rotating block 44 is fixedly connected to the rotating column 46. The top of the rotating column 46 is fixedly connected to the second connecting frame 45. The top of the second connecting frame 45 is fixedly connected to the side wall of the support frame 52. The top of the support frame 52 is mounted with a drive motor 51. The output end of the drive motor 51 is fixedly connected to the rotating rod 54. One end of the first mounting frame 61 is fixedly connected to the inner wall of the curved plate 57.

[0033] In this embodiment, during the display screen transfer operation, mobile platform 3 utilizes the principles of a motor and ball screw. The two mobile platforms 3 are then driven in tandem to smoothly move the mounted mobile plate 31 along a predetermined path. Simultaneously with the movement of mobile plate 31, the robotic arm 2 and adjustment mechanism 5 mounted thereon also move synchronously, achieving coordinated transfer of the entire structure. During this process, the adjustment mechanism 5, in conjunction with the visual positioning provided by the guide mechanism 6, enables dynamic, real-time correction of the display screen's transfer path and posture, ensuring precise guidance and path consistency during movement, effectively preventing offset and the accumulation of errors.

[0034] As the movable plate 31 continues to move, the first connecting frame 41 affixed thereto is also synchronously driven forward. The first connecting frame 41 is structurally connected to the connecting block 49 and the first sliding block 43, so its movement also drives the entire assembly. The first sliding block 43 is embedded in a slot 421 within the sidewall of the first slide rail 42 and can slide linearly within the slot 421, thereby limiting and guiding the lateral movement of the connecting structure, ensuring smooth movement and structural stability of the system.

[0035] As the first sliding block 43 gradually approaches the terminal position of the first slide rail 42, the contact plate 441 provided on the outer side of the first rotating block 44 comes into physical contact with the stop block 422. The force exerted on the contact plate 441 pushes the first rotating block 44 to rotate. During this rotation process, the first rotating block 44 applies a driving force to the connector 482, thereby further driving the movable rod 48 connected thereto to deflect and rotate.

[0036] One end of the movable rod 48 is connected to the second rotating block 47, which drives the second rotating block 47 to rotate synchronously. A spring 481 is provided, which releases elastic energy when compressed, providing a certain degree of reverse force to the first rotating block 44, achieving a rapid return movement. Simultaneously, a limit rod 431 effectively limits the rotation angle of the first rotating block 44, ensuring that its maximum rotation angle does not exceed 90 degrees, thus preventing structural interference or positional deviation.

[0037] A rotating column 46 is mounted atop the first rotating block 44. Driven by the rotating block, this column 46 rotates synchronously, thereby adjusting the angles of the adjustment mechanism 5 and guide mechanism 6 at the top of the second connecting frame 45. This structure maintains visual guidance even after the display screen has been transferred to the target workstation, ensuring that the adjustment mechanism 5 and guide mechanism 6 can still provide short-term auxiliary positioning even at the end of the transfer. This allows for highly precise placement and alignment of the display screen at the workstation, effectively improving the operational accuracy and automation efficiency of the overall system.

[0038] Example 4: According to Figure 8-Figure 9 As shown, a visual guidance system is also included, which includes an adjustment module 72, a visual detection module 75 and a grasping module 77. The adjustment module 72 is internally provided with an angle module 73 and a reversing module 74. The adjustment module 72 is used to change the position of the guide mechanism 6 and expand the monitoring range of the camera.

[0039] The visual detection module 75 is signal-connected to the adjustment module 72 and the grasping module 77 respectively. The visual detection module 75 is used to receive the angle adjustment signal and the reversing signal transmitted by the adjustment module 72 and transmit them to the monitoring camera 66.

[0040] A sensor module 78 is provided inside the grasping module 77. The grasping module 77 is used to control the robotic arm 2 to perform grasping operations. The sensor module 78 can be used to understand the grasping situation in real time to ensure accurate grasping.

[0041] It also includes a collaborative module 71, which is signal-connected to the adjustment module 72 and the visual detection module 75, and one end of the collaborative module 71 is signal-connected to the conveying module 7 and the moving module 76. The conveying module 7 is used to convey the display screen component to the bottom of the robotic arm 2. After the collaborative module 71 receives the monitoring signal from the visual detection module 75, the conveying module 7 can control the conveyor belt 1 to start and stop.

[0042] The moving module 76 transmits a moving signal to the moving platform 3, so that the moving platform 3 drives the moving plate 31 on the top to move, thereby changing the position of the robot arm 2 and the adjustment mechanism 5, thereby indirectly changing the position of the monitoring camera 66, so as to facilitate visual guidance during feeding.

[0043] In this embodiment, conveyor module 7 first controls the movement of conveyor belt 1 along a preset trajectory to transport the display screens. To accommodate varying production schedules and complex routing requirements, multiple conveyor belts 1 can be added to enable batch or parallel transport of displays. The system possesses real-time control capabilities, dynamically adjusting the speed and path of conveyor belt 1 based on process requirements to ensure that each display screen is stably delivered to the preset position below robotic arm 2. When a display screen reaches its target position, conveyor belt 1 receives a stop signal from conveyor module 7 and rapidly brakes, providing a static and stable operating environment for subsequent grasping operations.

[0044] Subsequently, surveillance camera 66 activates, performing a multi-angle, all-around scan of the display screen surface and its posture. This phase includes several key inspection tasks: identifying the display screen's edges and corners, calculating the deviation between the actual placement angle and the standard posture, accurately determining the relative position between the display screen and the end effector of robotic arm 2, inspecting the display screen for defects such as damage, cracks, and scratches, and generating image recognition results. All inspection results are packaged as detection signals and uploaded to collaborative module 71, serving as important input for subsequent grasping strategies.

[0045] After monitoring confirms the display screen is functioning properly, the gripping module 77 issues a gripping command, driving the robotic arm 2 to initiate the gripping process. At this point, the robotic arm 2 slowly lowers the suction cup at its end, performing high-precision positioning and suction under the visual guidance of the surveillance camera 66. To ensure the stability and safety of the suction process, the sensor module 78 is introduced to collect parameters such as the suction cup's suction force and contact state in real time. These parameters are then integrated and analyzed with the posture data from the surveillance camera 66 and uploaded to the collaboration module 71 for global judgment.

[0046] During the grasping process, the collaborative module 71 will also record the following key status information: whether the display screen is offset or tilted due to excessive grasping force or displacement of the suction cup, whether there are foreign objects, impurities and other risk factors under the display screen that affect subsequent placement operations, and whether the display screen posture matches the planned path.

[0047] Based on these real-time collected data, the movement trajectory of the robotic arm 2 can be dynamically fine-tuned to ensure that the display screen always remains stable and has the correct posture during movement, preventing secondary damage caused by vibration or tilt.

[0048] Once the display screen has been transferred to the target workstation, surveillance camera 66 turns again, coordinating with robotic arm 2's terminal positioning motion to provide visual guidance during the placement process. Robot arm 2 slowly descends to a predetermined height and, based on the final posture detection data, fine-tunes the suction cup release point to ensure the display screen is precisely placed in the designated area of ​​the workstation. After confirming that both position and angle errors are within tolerance, the suction cup releases, completing the cycle.

[0049] If, at any stage of the process, surveillance camera 66 detects damage or other substandard features on a display screen, it immediately sends an exception signal to collaboration module 71. Collaboration module 71 interrupts the current grab or transfer command of robot arm 2 and initiates an exception handling process, directing robot arm 2 to transport the display screen to a designated waste area to prevent defective products from entering subsequent processes, thereby ensuring consistent and stable quality across the entire production line.

[0050] The device's usage and operating principles are as follows: Conveyor module 7 controls conveyor belt 1 to transport the display screens. Multiple conveyor belts 1 can be added during the feeding process, enabling real-time control and route adjustment. When the display screen reaches a designated position below robotic arm 2, conveyor belt 1 brakes upon receiving a stop signal. A monitoring camera 66 then scans the display screen in all directions, detecting its angular deviation and positional offset from the gripping point of robotic arm 2. It also identifies surface defects such as damage and cracks and generates a detection signal.

[0051] If the display screen is in normal condition, the gripping module 77 sends a gripping command to the robotic arm 2. The robotic arm 2 drives the end suction cup downward, precisely aligning and adsorbing the display screen under the visual guidance of the monitoring camera 66. During the gripping process, the monitoring camera 66 collects real-time data on the display screen's posture after gripping. To adjust the camera angle, the reduction motor 62 rotates the drive rod 621, synchronously moving the two second transmission rods 681. The second transmission rods 681 transmit force to the two first transmission rods 671 via the first connecting rod 68, which in turn pushes the mounting rod 67 to move the second mounting bracket 65. During this process, the two first connecting rods 68 maintain stable motion in coordination with the third transmission rod 682. The second mounting bracket 65 drives the second sliding block 64 along the trajectory defined by the curved track 631, thereby changing the angle of the monitoring camera 66. This enables real-time monitoring of the robotic arm 2 as it picks up and transfers the display screen, as well as observation of the situation below the display screen after gripping is complete, thus guiding the robotic arm 2 in all directions of feeding.

[0052] When the drive motor 51 rotates the rotating rod 54, it drives the gear 55, which in turn pushes the curved rack 56, which in turn moves the curved plate 57, thereby adjusting the position of the guide mechanism 6 and expanding the monitoring range of the surveillance camera 66. The sensor module 78 monitors the gripping status of the suction cup in real time, transmitting this data to the coordination module 71, which determines whether the display screen is offset or tilted due to the gripping force and records the presence of foreign objects beneath the display screen, providing a reference for subsequent workstation placement. The system fine-tunes the movement trajectory of the robotic arm 2 based on the visual data to ensure a stable transfer process.

[0053] The two mobile platforms 3 drive the movement of the moving plate 31, which in turn drives the movement of the robotic arm 2 and the adjustment mechanism 5. During the transfer process, the adjustment mechanism 5 and the guide mechanism 6 maintain synchronous movement through visual guidance. The various components of the transposition mechanism 4 work together to control the rotation of the adjustment mechanism 5 and the guide mechanism 6 at the top of the second connecting frame 45, ensuring that the display screen can still be accurately placed after being transferred to the workstation through short-term visual guidance.

[0054] Guided by the vision of the turned surveillance camera 66, robotic arm 2 slowly descends and places the display screen at the designated location on the workstation. The camera then verifies the display screen's placement and positional deviation for a final time. Once confirmed, robotic arm 2 releases the suction cup, completing the transfer process. If surveillance camera 66 detects damage to the display screen at any stage, it immediately sends an abnormality signal to coordination module 71, which then terminates robotic arm 2's grab and transfer instructions and transfers the damaged part to the scrap area.
