Description

Technical Field

[0001] This utility model relates to the field of LED display module appearance defect detection technology, and in particular to an LED display module appearance defect detection device. Background Technology

[0002] Visual defect detection of LED display modules is a crucial step in ensuring the quality and reliability of LED displays. By detecting visual defects, various defects that may occur during the manufacturing, transportation, or installation of LED display modules can be identified and addressed in a timely manner, ensuring the overall performance and safety of the product.

[0003] Currently, commonly used visual inspection equipment uses high-precision cameras to accurately identify scratches, stains, cracks, and assembly defects on modules. However, this type of visual inspection equipment can only mark the location of defects and cannot automatically remove problematic units from the production line in real time, which limits the degree of automation in the production process and affects overall production efficiency and product quality.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] Please see Figures 1 to 5 The present invention provides an LED display module appearance defect detection device, which includes a support component 10, a detection component 20 installed inside the support component 10, and a removal component 30 connected to the detection component 20.

[0030] The support assembly 10 includes a frame 11, an X-axis linear module 12 installed in the middle of the frame 11, a carrier plate 13 connected to the X-axis linear module 12, a plurality of electromagnets 14 evenly spaced on the carrier plate 13, support pads 15 located in the middle of opposite ends of the carrier plate 13, guide limiting blocks 16 installed on opposite sides of each support pad 15, and a cover 17 installed on the top of the frame 11.

[0031] Conveyor belts (not shown) are connected to opposite sides of the frame 11. Specifically, the conveyor belts are positioned at the ends of the support pads 15 away from the carrier plate 13. One conveyor belt is used for loading LED display modules 40, and the other conveyor belt is used for unloading LED display modules 40. The LED display modules 40 slide against the top of the support pads 15. The LED display modules 40 are located on two guide limit blocks 16 to effectively guide the LED display modules 40 to transfer onto the carrier plate 13, where they are positioned and attracted by electromagnets 14.

[0032] In this embodiment, the height of the support pad 15 is less than the height of the guide limit block 16.

[0033] In this embodiment, the conveying direction of the conveyor belt is consistent with the Y-axis direction, that is, the conveying direction of the conveyor belt is perpendicular to the movement direction of the X-axis linear module 12.

[0034] The detection component 20 is located above the carrier plate 13. The detection component 20 includes a Y-axis linear module 21 installed in the middle of the frame 11, a movable support 22 connected to the Y-axis linear module 21, and two cameras 23 fixedly installed on the top of the movable support 22.

[0036] In practical operation, the X-axis linear module 12 drives the carrier plate 13 to move along the X-axis, and the Y-axis linear module 21 drives the camera 23 to move along the Y-axis, achieving comprehensive inspection of the entire LED display module 40. Once the camera 23 detects a problematic unit, the removal component 30 is activated, precisely picking up the problematic unit via a vacuum suction head 33 and transferring it to the removal conveyor belt 34 for removal. This facilitates subsequent filling and repair of the blank areas in the LED display module 40, effectively reducing the intensity of subsequent maintenance, greatly improving the automation level of the production process, and ensuring overall production efficiency and product quality.

[0037] In this embodiment, the linear module 31 is removed and positioned along the Y-axis.

[0038] The aforementioned LED display module appearance defect detection device has a simple structure and is easy to use. The X-axis linear module 12 drives the carrier plate 13 to move along the X-axis direction, and the Y-axis linear module 21 drives the camera 23 to move along the Y-axis direction, which can realize a comprehensive inspection of the entire LED display module 40. After the removal component 30 works together to accurately pick up the problematic unit and remove it, it is convenient to fill the blank areas of the LED display module 40 for subsequent repairs, effectively reducing the intensity of subsequent repairs, greatly improving the automation level of the production process, and ensuring overall production efficiency and product quality.
