[0040] This utility model proposes a fully automatic testing device for LED modules, which is mainly used for testing LED modules.
[0041] Reference Figure 1 As shown, in one embodiment of this utility model, the fully automatic LED module testing equipment includes:
[0042] The frame 100 has a conveying device 300 on its surface for transporting the carrier 200, which carries the workpiece 400 to be tested.
[0043] The control device 500 is located below the frame 100 and is electrically connected to the conveying device 300. It is used to control the start and stop of the conveying device 300.
[0044] The detection device 600 is located on one side of the conveying device 300. The detection device 600 can move relative to the carrier 200. The detection device 600 is used to detect the workpiece 400 to be tested.
[0045] In this embodiment, the frame 100 is the basic support structure of the entire equipment, used to fix and install core components such as the conveying device 300, the detection device 600, and the control device 500. The frame 100 is made of a robust metal material (such as steel or aluminum alloy) to ensure the stability and durability of the system. Casters are installed at the bottom of the frame 100 to adapt to the position requirements of different working environments. In addition, the frame 100 is also equipped with cable routing channels and interface brackets to facilitate the arrangement and connection of circuits for various components, ensuring the safety and neatness of system operation.
[0046] In this embodiment, the conveying device 300 is mounted on the surface of the frame 100. Its function is to transport the carrier 200 along a predetermined path, ensuring that the carrier 200 can enter the inspection area in sequence. The conveying device 300 can be a belt conveyor, a roller conveyor, or a chain conveyor, and can be flexibly configured according to production needs. The operating speed of the conveying device 300 can be adjusted by the control device 500 to adapt to the inspection rhythm of different workpieces 400. The conveying device 300 is equipped with a sensing sensor to detect the position and status of the carrier 200, thereby achieving precise positioning and ensuring that the inspection device 600 completes its operation at the appropriate time. At the same time, the conveying device 300 has an automatic stop function. When an abnormal situation is detected (such as the carrier 200 jamming or the workpiece 400 falling off), it can automatically stop the transmission to prevent damage to the equipment and the workpiece 400.
[0047] In this embodiment, the carrier 200 is a support tool for carrying the workpiece 400 to be tested. Its surface is provided with grooves or clamps to fix the workpiece 400 to be tested, ensuring that the workpiece 400 remains stable during transportation and that the test results are not affected by vibration or displacement. The carrier 200 is made of a high-strength composite material that is wear-resistant and not easily deformed to meet the needs of long-term use.
[0048] In this embodiment, the detection device 600 is located on one side of the conveying device 300 and is specifically used for performance or quality detection of the workpiece 400 on the carrier 200. The detection device 600 can be of various types depending on the detection requirements, such as a visual inspection device, a measuring sensor, or a functional testing device (e.g., continuity, resistance, high voltage, and current functional tests). Visual inspection devices can be used for appearance inspection, identifying surface defects or dimensional errors of the workpiece 400; measuring sensors can be used to detect specific dimensions or weights of the workpiece 400; and functional testing devices can test the electronic performance or functional status of the workpiece 400 through an electronic interface. The detection device 600 has high detection accuracy and can complete the measurement of all workpieces 400 on a carrier 200 in a short time. The detection device 600 is also equipped with auxiliary devices such as automatic alignment and light source adjustment to adapt to the detection requirements of different workpieces 400 and ensure detection accuracy under various ambient light conditions.
[0049] In this embodiment, the control device 500 is located below the frame 100 and is connected to the conveying device 300 via a cable. It can start, stop and adjust the running speed of the conveying device 300, thereby controlling the position of the carrier 200 on the conveying device 300, so that the carrier 200 can stop accurately on the side of the detection device 600, which facilitates the detection device 600 to detect the workpiece 400 to be tested.
[0050] In the fully automatic LED module testing equipment of this embodiment, when the workpiece 400 to be tested is transported to the testing area by the conveying device 300, the control device 500 controls the conveying device 300 to stop working, and at the same time the testing device 600 starts to test the workpiece 400, and performs multiple functional tests such as continuity, resistance, high voltage, and current in one go. By testing multiple workpieces 400 at the same time by the testing device 600, the testing efficiency is improved.
[0051] Reference Figure 2 As shown, in one embodiment, the vehicle 200 includes:
[0052] Fixing blocks 210, at least two fixing blocks 210, are used to clamp the diagonal of the workpiece 400 to be measured;
[0053] Connection points 220 are located on both sides of the workpiece 400 to be tested and are electrically connected to the workpiece 400 to be tested.
[0054] Test contact 230, electrically connected to connection point 220, is located on the side of carrier 200 facing detection device 600, and is used to contact detection device 600 to receive detection signals.
[0055] In this embodiment, the main function of the fixing blocks 210 is to clamp the workpiece 400 to be tested, ensuring that the workpiece 400 will not shift or loosen during the entire testing process. Each workpiece 400 to be tested is provided with at least two fixing blocks 210. The fixing blocks 210 clamp the workpiece 400 diagonally, ensuring the stability of the workpiece 400 on the carrier 200. The fixing blocks 210 are made of wear-resistant and appropriately elastic materials (such as aluminum alloy or engineering plastics), which can prevent damage to the surface of the workpiece 400 when clamping it. The fixing blocks 210 achieve clamping through elastic structures, pneumatic or mechanical means, and can adapt to workpieces 400 of different sizes and shapes. For example, using a mechanical clamping device, the operator adjusts the diagonal distance between the fixing blocks 210 according to the shape and size of the workpiece 400 to avoid over-clamping causing damage to the workpiece 400, or insufficient clamping force causing the workpiece 400 to loosen. The fixing block 210 ensures the horizontal and vertical positioning of the workpiece 400 in the carrier 200 by clamping the diagonal points of the workpiece 400 to be tested.
[0056] In this embodiment, connection points 220 are disposed on both sides of the workpiece 400 to be tested, for electrical connection with the workpiece 400. Connection points 220 typically employ metal contact pieces or electrical connectors to ensure stable transmission of detection signals with the workpiece 400. Connection points 220 can be designed with elastic contact; when the workpiece 400 is placed on the carrier 200, the connection points 220 automatically align with both sides of the workpiece 400, completing the electrical connection. To accommodate workpieces 400 of different sizes and shapes, connection points 220 can be designed to be adjustable, for example, by using springs or fine-tuning screws to adjust the contact pressure and contact position of the connection points 220.
[0057] In this embodiment, the test contact 230 is a specially designed part on the carrier 200 for contacting the detection device 600. The test contact 230 and the connection point 220 are electrically connected, and the connected circuit is hidden inside the carrier 200. The test contact 230 receives the detection signal from the detection device 600 and transmits it to the connection point 220, thereby detecting the workpiece 400 under test. The test contact 230 can be located on the side of the carrier 200 facing the detection device 600 to ensure that the test contact 230 can accurately align with the detection probe or electrical connector of the detection device 600 after the carrier 200 enters the detection area. The test contact 230 can be designed as a flexible contact, adjusted by a spring or flexible material to ensure a stable contact signal with the detection device 600 and avoid signal loss due to poor contact or interference.
[0058] In this embodiment, the carrier 200 is used to fix the workpiece 400 to be tested and connect it to the testing device 600 to ensure that the workpiece 400 to be tested can stably and reliably transmit and receive testing signals during the testing process. The carrier 200 includes a fixing block 210, a connection point 220 and a test contact 230. Through the cooperation of these components, the carrier 200 can achieve precise fixation of the workpiece 400 and signal transmission.
[0059] Reference Figure 3 and Figure 4 As shown, in one embodiment, a blocking device 700 is also included. The blocking device 700 is electrically connected to the control device 500 and is used to block the movement of the vehicle 200. The blocking device 700 includes a first blocking cylinder 710 and a second blocking cylinder 720. The first blocking cylinder 710 is used to fix the vehicle 200, and the second blocking cylinder 720 is used to block another vehicle 200.
[0060] In this embodiment, the first blocking cylinder 710 is used to fix the carrier 200 in the detection area, ensuring that the carrier 200 does not move arbitrarily. The second blocking cylinder 720 is used to block carriers 200 that have not completed detection when multiple carriers 200 pass through in sequence, preventing them from entering the area being detected, thereby ensuring the order and stability of the detection. The first blocking cylinder 710 and the second blocking cylinder 720 are arranged sequentially along the conveying direction of the carrier 200. The first blocking cylinder 710 can be set in the detection area so that the carrier 200 is fixed next to the detection device 600, while the second blocking cylinder 720 can be set at the feed point of the detection area to block carriers 200 that have not yet completed detection. Both blocking cylinders include a sliding cylinder 730 and a blocking piston rod 740. One end of the blocking piston rod 740 is fixedly connected to a blocking block 750, and the blocking piston rod 740 can move up and down under the drive of the sliding cylinder 730. The two sliding cylinders 730 mentioned above are connected to the control device 500 through an electronic control system to control the movement of the sliding cylinders 730 according to the needs of the equipment, thereby achieving precise control of the vehicle 200.
[0061] In this embodiment, the first blocking cylinder 710 and the second blocking cylinder 720 can be used in conjunction. When multiple vehicles 200 enter the detection area sequentially, the first blocking cylinder 710 operates, pushing the blocking block 750 to fix the vehicle 200 in a designated position, ensuring that it does not shift. Simultaneously, the second blocking cylinder 720 operates, pushing the blocking block 750 to block other vehicles 200 that have not yet entered the detection area, preventing them from entering the area being detected and ensuring that each vehicle 200 has sufficient time to complete the detection. Only after the first blocking cylinder 710 releases the vehicle 200 from the detection area will the second blocking cylinder 720 release the obstruction, allowing the next vehicle 200 to smoothly enter the detection area.
[0062] In this embodiment, the coordinated operation of the first blocking cylinder 710 and the second blocking cylinder 720 ensures that each carrier 200 has sufficient detection time and prevents collisions or sequence errors of the carriers 200, thus guaranteeing the efficiency and accuracy of the entire detection process of the workpiece 400 to be tested.
[0063] Reference Figure 5 As shown, in one embodiment, the conveying device 300 includes a first speed chain 310, a second speed chain 320, and a drive device 330. The first speed chain 310 and the second speed chain 320 are fixedly mounted in parallel on the frame 100 for transporting the carrier 200. The first speed chain 310 is electrically connected to the control device 500.
[0064] In this embodiment, the conveying device 300 uses a double-speed chain to transport the carrier 200. The driving device drives the first double-speed chain 310 and the second double-speed chain 320 to rotate synchronously. The first double-speed chain 310 and the second double-speed chain 320 are arranged in parallel, and the distance between them is the width of the carrier 200. A detection device 600 is provided on the side of the first double-speed chain 310 away from the second double-speed chain 320, and a first blocking cylinder 710 and a second blocking cylinder 720 are provided on the inner side between them.
[0065] In one embodiment, the carrier 200 further includes a guide hole 240, which is fixed on the same side of the test contact 230.
[0066] In this embodiment, the guide holes 240 are evenly spaced next to the test contacts 230 to fix the carrier 200 and the testing device 600 during testing, ensuring the stability of the connection between the test contacts 230 and the testing device 600.
[0067] Reference Figure 6 and Figure 7 As shown, in one embodiment, the detection device 600 further includes:
[0068] Linear guide rail 610 is fixed to frame 100;
[0069] The detection bracket 620 is slidably connected to the linear guide rail 610 and is used to bring the detection probe 630 closer to or away from the carrier 200; the detection probe 630 is mated with the test contact 230.
[0070] A drive cylinder 640 is mounted on the frame 100 and is used to drive the detection bracket 620 to slide along the linear guide rail 610.
[0071] In this embodiment, the linear guide 610 includes a guide rail 611 and a slider 612. The guide rail 611 is horizontally mounted on the frame 100, and the slider 612 is connected to the detection bracket 620. The detection bracket 620 slides along the guide rail 611 via the slider 612. Through the linear guide 610, the detection probe 630 can quickly and accurately mate with the test contact 230.
[0072] In this embodiment, the detection bracket 620 further includes a first support plate 621, a second support plate 622, and a bending plate 623. The first support plate 621 is placed vertically, with the detection probe 630 fixedly connected to the side facing the carrier 200, and one end of the bending plate 623 fixedly connected to the side facing away from the carrier 200. The second support plate 622 is placed horizontally, with a slider 612 on its lower surface that cooperates with the guide rail 611, and the other end of the bending plate 623 fixedly connected to its upper surface.
[0073] In this embodiment, the drive cylinder 640 is positioned at the center of the detection bracket 620, facilitating its smooth movement. The drive cylinder 640 includes a cylinder 641 and a piston rod 642. The piston rod 642 is fixedly connected to or snapped into the second support plate 622, while the cylinder 641 is fixed to the frame 100. Changes in air pressure within the cylinder 641 drive the piston rod 642, thereby causing the detection bracket 620 to slide along the linear guide rail 610, precisely adjusting the position of the detection probe 630. The use of the cylinder 641 provides high-precision linear drive while also achieving a fast response speed.
[0074] Reference Figure 6 and Figure 7 As shown, the detection device 600 also includes a guide pin 650, which is correspondingly disposed with the guide hole 240. The guide pin 650 is engaged with the guide hole 240 to correct the position of the carrier 200.
[0075] In this embodiment, a guide pin 650 is also provided on the side of the first support plate 621 facing the carrier 200. The guide pin 650 can engage with the guide hole 240 to further correct the position of the carrier 200. At the same time, the guide pin 650 can engage with the guide hole 240 to fix the detection device 600 and the carrier 200 during detection, ensuring that the detection probe 630 and the test contact 230 can make stable contact.
[0076] Reference Figure 6 and Figure 7 As shown, in one embodiment, the detection device 600 further includes a limiting block 660, which is fixed to the end of the linear guide rail 610 away from the carrier 200, and is used to block the movement of the detection bracket 620.
[0077] In this embodiment, the limiting block 660 is located near the drive cylinder 640 and can abut against the second support plate 622, thereby limiting the displacement of the piston rod 642 of the cylinder during its return stroke, thus limiting the movement distance of the detection bracket 620 when it is away from the carrier 200. This prevents the detection bracket 620 from slipping off the linear guide rail 610.
[0078] Reference Figure 7 As shown, in one embodiment, the detection bracket 620 is provided with a T-shaped hole 670; the T-shaped hole 670 is engaged with the piston rod 642 of the drive cylinder 640.
[0079] Reference Figure 8As shown, in this embodiment, a T-shaped hole 670 is provided on the second support plate 622, which engages with the piston rod 642 of the drive cylinder 640. This engagement design allows the second support plate 622 to move horizontally along the linear guide rail 610 driven by the piston rod 642, while vertically, the operator can remove the second support plate 622 to remove the entire inspection bracket 620 for replacement or repair, adapting to different inspection conditions and the workpiece 400 to be inspected.
[0080] Reference Figure 9 As shown, in one embodiment, the carrier 200 further includes a plurality of positioning through holes 250, which are formed on the surface of the carrier 200 for adjusting the distance of the fixing block 210.
[0081] In this embodiment, the surface of the carrier 200 is provided with a plurality of positioning through holes 250. The fixing block 210 can be fixed by setting a fixing post through the through hole, thereby changing the distance between the two fixing blocks 210 to adapt to the fixing of workpieces 400 of different shapes and sizes.
