Description

Technical Field

[0001] This invention relates to the field of LED screen testing technology, specifically to an LED screen testing device. Background Technology

[0002] LED displays are a type of display that controls semiconductor light-emitting diodes. They are composed of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixels arranged evenly. Rental displays use SMD surface mount three-in-one packaging technology, which is ultra-light, ultra-thin, space-saving, and can be spliced ​​in any direction, size, and shape. They are suitable for theme parks, bars, auditoriums, theaters, parties, building curtain walls and other occasions.

[0003] Existing LED displays require testing during manufacturing. This involves connecting the LED display to a power source to observe whether it lights up normally and to check if the touch function is working properly. In current methods, the LED display is pre-connected with ribbon cables, then placed in a dedicated slot, and the other end of the ribbon cable is manually connected to the screen output device before observing whether it lights up normally and checking if the touch function is working properly.

[0004] During the process of placing the LED display screen into the dedicated slot, there is a problem of the ribbon cable becoming detached from the LED display screen.

[0016] As a preferred technical solution of the present invention: the limiting block has a fitting surface and a limiting surface on the side near the connecting platform, and the fitting surface and the limiting surface are arranged perpendicularly.

[0017] The present invention has the following beneficial effects:

[0018] 1. This LED screen testing equipment uses a robotic arm to move a clamping arm. The six-axis rotation of the robotic arm allows it to directly grip the screen body on the storage platform, moving it directly to the bottom of the capacitive touch pen. This enables the touch pen to test the screen body. By directly gripping the screen body, the touch detection and image acquisition components can perform the testing directly on the clamping arm, avoiding the steps required in traditional equipment where the screen body needs to be placed on a specific platform before testing by the touch detection and image acquisition components. This improves the testing efficiency of the equipment.

[0019] 2. This LED screen testing equipment uses a clamping arm to hold the screen body and outputs images to the screen body as the testing robot arm moves the screen body through the clamping arm. This solves the problem in traditional methods where the ribbon cable can detach from the LED display screen during the process of placing the LED display screen in a dedicated slot.

[0020] 3. This LED screen testing equipment features a vertically aligned bonding surface and a limiting surface. When the clamping seat moves the limiting block to hold the screen body, the outer wall of the bonding surface is in contact with the side wall of the screen body, while the outer wall of the limiting surface is in contact with the vertical surface of the side wall of the screen body. Therefore, when the telescopic device moves the sliding rod via the connecting plate, causing the sliding rod to move the limiting block through the clamping seat to hold the screen body, the bonding surface simply needs to remain in contact with the side wall of the screen body. During the movement of the screen body by the testing robotic arm through the clamping arm, the downward force of the screen body is applied to the limiting block through the limiting surface. The limiting block rotates under this force, causing the bonding surface to press against the side wall of the screen body, thus maintaining the clamping of the screen body. This solves the problem of traditional clamping equipment causing damage to the clamped item due to excessive clamping pressure, and causing the clamped item to fall due to insufficient clamping pressure.

[0043] In a preferred embodiment: the touch detection component 2 includes a mounting platform 201, a slide 202 fixedly mounted on the top of the mounting platform 201, a lead screw 203 rotatably connected to the inner wall of the top of the slide 202, a slide base 204 slidably sleeved on the top of the slide 202, a slide 205 fixedly mounted on the top of the slide base 204, a lead screw 206 rotatably connected to the inner wall of the top of the slide 205, a slide base 208 slidably sleeved on the top of the slide 205, a drive motor 207 fixedly mounted at the end of the slide 205, a detection seat 209 fixedly mounted on the outer wall of the slide base 208 near the detection robotic arm 4, and a capacitive stylus 210 fixedly mounted on the bottom of the detection seat 209.

[0044] In a preferred embodiment: the touch detection component 2 is fixedly assembled on the top of the mounting platform 201 and the worktable 1, the lead screw 203 and the inner wall of the slide 204 are threadedly connected, the end of the slide 202 is also fixedly assembled with a drive motor for driving the lead screw 203, the lead screw 206 and the inner wall of the slide 208 are threadedly connected, and the output end of the drive motor 207 is fixedly assembled with the lead screw 206.

[0045] In the above structure, the lead screw 203 is rotated by the drive motor, and the slide block 204 and the slide table 202 are slidably connected, and the slide block 204 and the lead screw 203 are threadedly connected, so that the slide block 204 can move along the slide table 202 along the X-axis.

[0046] The drive motor 207 drives the lead screw 206 to rotate, and the slide block 208 and the slide table 205 are slidably connected, and the slide block 208 and the lead screw 206 are threadedly connected, so that the slide block 208 can move along the slide table 205 along the Y-axis.

[0047] When the detection robotic arm 4 moves the screen body 5 to the bottom of the capacitive stylus 210, the touch detection component 2 can drive the capacitive stylus 210 to move along the X and Y axes, thereby enabling the capacitive stylus 210 to perform touch detection on the screen body 5.

[0048] In a preferred embodiment: the image acquisition component 3 includes a mounting platform 301, a slide 302 is fixedly mounted on the outer wall of the mounting platform 301 near the detection robotic arm 4, a slide block 305 is slidably sleeved on the outer wall of the slide 302, a lead screw 304 is rotatably connected to the inner wall of the slide 302, a drive motor 303 is fixedly mounted on the bottom of the slide 302, and a camera 306 is fixedly mounted on the outer wall of the slide block 305.

[0049] The output shaft of drive motor 2 303 is fixedly assembled with slide table 3 302, and slide table 3 302 and slide block 3 305 are connected by threads on their inner walls.

[0050] In the above structure, the drive motor 303 drives the slide 302, and the slide 305 and the slide 302 are connected by a thread, so that the slide 305 drives the camera 306 to move up and down. Then, when the detection robot arm 4 moves the screen body 5 to the bottom of the camera 306, the camera 306 can adjust its focal length by moving up and down.

[0051] In a preferred embodiment: the detection robotic arm 4 includes a mounting plate 401, a turntable 402 is fixedly mounted on the top of the mounting plate 401, a robotic arm 403 is rotatably connected to the top of the turntable 402, a robotic arm 404 is rotatably connected to the top of the robotic arm 403, a robotic arm 405 is rotatably connected to the inner wall of the end of the robotic arm 404 away from the robotic arm 403, a robotic arm 406 is rotatably connected to the end of the robotic arm 405 away from the robotic arm 404, a robotic arm 407 is rotatably connected to the inner wall of the end of the robotic arm 406 away from the robotic arm 405, and a clamping arm 408 is rotatably connected to the outer wall of the end of the robotic arm 407 away from the robotic arm 406.

[0052] In a preferred embodiment: the detection robotic arm 4 is fixedly assembled to the top of the worktable 1 via the mounting plate 401. The inner cavities of the turntable 402, robotic arm 1 403, robotic arm 2 404, robotic arm 3 405, robotic arm 406, and robotic arm 5 407 are all embedded with drive motors. The turntable 402 rotates with robotic arm 1 403 via the operation of the drive motor. The robotic arm 1 403 rotates with robotic arm 2 404 via the operation of the drive motor. The robotic arm 3 405 rotates with each other via the operation of the drive motor. The robotic arm 3 405 rotates with robotic arm 406 via the operation of the drive motor. The robotic arm 406 rotates with robotic arm 5 407 via the operation of the drive motor. The robotic arm 5 407 rotates with the gripping arm 408 via the operation of the drive motor.

[0053] In the above structure, the detection robotic arm 4 drives the clamping arm 408 to move. Through the six-axis rotation of the detection robotic arm 4, the detection robotic arm 4 can drive the clamping arm 408 to directly clamp the screen body 5 on the storage platform, and move the screen body 5 directly to the bottom of the capacitive stylus 210, realizing the detection of the screen body 5 by the capacitive stylus 210. By setting the clamping arm 408 to directly clamp the screen body 5, the process of the touch detection component 2 and the image acquisition component 3 detecting the screen body 5 can be directly performed on the clamping arm 408. This avoids the steps in traditional equipment, which require the screen body 5 to be placed on a specific storage platform and then detected by the touch detection component 2 and the image acquisition component 3, thus improving the detection efficiency of the equipment.

[0054] In a preferred embodiment: the plug-in component includes a fixed plate 40810 and a sliding plate 40813. A drive motor 40811 is fixedly mounted on the inner wall of the middle part of the fixed plate 40810. A lead screw 40812 is fixedly mounted on the output shaft of the drive motor 40811. A telescopic device 40814 is fixedly mounted on one end of the sliding plate 40813. A plug-in male socket 40815 is fixedly mounted on the telescopic end of the telescopic device 40814 near the screen body 5.

[0055] The ends of the connecting plate 4087 and the slide rod 4085 are fixedly assembled; the fixing plate 40810 and a set of slide rods 4085 are fixedly assembled; the sliding plate 40813 and a set of slide rods 4085 are slidably sleeved; the lead screw 40812 and the inner wall of the sliding plate 40813 are threadedly connected; and the connecting platform 4081 and the drive motor output shaft embedded in the inner cavity of the robotic arm 407 are fixedly assembled.

[0056] The clamping arm 408 is fixedly assembled with the drive motor output shaft embedded in the inner cavity of the robotic arm 407 via the connecting platform 4081, so that the clamping arm 408 can be driven to rotate by the drive motor embedded in the inner cavity of the robotic arm 407.

[0057] By setting the rubber adsorption seat 40816 on one side close to the screen body 5, connecting the rubber adsorption seat 40816 to the negative pressure machine, and controlling the negative pressure output by the negative pressure machine to the rubber adsorption seat 40816 through the control equipment, the screen body 5 can achieve negative pressure adsorption through the rubber adsorption seat 40816.

[0058] The expansion joint 4086 moves the slide rod 4085 on the inner wall of the slide groove 4084 via the connecting plate 4087, thereby causing the two sets of slide rods 4085 to drive the card seat 4088 to expand and retract.

[0059] The screen body 5 also includes a plug-in female socket 501 that is fixedly assembled with the screen body 5. When the plug-in female socket 501 is installed on the outer wall of the screen body 5 by the equipment, the position of the plug-in female socket 501 on the outer wall of the screen body 5 is fixed. At the same time, the length and width data of several screen bodies 5 in the same batch are consistent.

[0060] Therefore, by pre-setting the length and width data of the screen body 5 and the position data of the plug-in female connector 501 installed on the outer wall of the screen body 5 in the control device, the telescopic device 4086 can drive the sliding rod 4085 through the connecting plate 4087 during the movement of the detection robotic arm 4, so that the two sets of sliding rods 4085 clamp the screen body 5 through the limit block 4089 and cancel the negative pressure adsorption of the rubber adsorption seat 40816 on the screen body 5. At the same time, the two sets of sliding rods 4085 move the screen body 5 left and right through the limit block 4089, so that the positions of the plug-in male connector 40815 and the plug-in female connector 501 correspond, and the telescopic device 40814 drives the plug-in male connector 40815 to plug into the plug-in female connector 501, so that the screen body 5 can achieve data connection and thus realize screen display.

[0061] The drive motor 40811 drives the lead screw 40812 to rotate. The lead screw 40812 is threadedly connected to the sliding plate 40813, so the sliding plate 40813 can move along the slide rod 4085 through the rotation of the drive motor 40811. In turn, the sliding plate 40813 drives the male connector 40815 to move through the telescopic device 40814. The simultaneous movement of the male connector 40815 and the slide rod 4085 and the screen body 5 can further increase the insertion efficiency of the male connector 40815 and the female connector 501.

[0062] By using two sets of sliding rods 4085 to clamp the screen body 5 through the limiting block 4089, and canceling the negative pressure adsorption of the rubber adsorption seat 40816 on the screen body 5, the time of using negative pressure of the rubber adsorption seat 40816 can be reduced, thereby reducing the number of times the negative pressure machine runs, thus achieving energy saving.

[0063] The detection robotic arm 4 clamps the screen body 5 through the clamping arm 408 and moves it to the bottom of the capacitive stylus 210. The touch detection component 2 drives the capacitive stylus 210 to move along the X and Y axes, thereby enabling the capacitive stylus 210 to perform touch detection on the screen body 5. While the capacitive stylus 210 is detecting the screen body 5, the camera 306 detects and collects the real-time image of the screen body 5. The collected data is matched in real time through the cloud to obtain the detection result of the capacitive stylus 210 on the screen body 5.

[0064] The screen body 5 is held by the clamping arm 408, and the screen body 5 is output as the detection robot arm 4 moves the screen body 5 through the clamping arm 408. This optimizes the traditional steps of placing the screen body 5 on a specific platform and then detecting it through the touch detection component 2 and the image acquisition component 3, thereby improving the detection efficiency of the device.

[0065] In a preferred embodiment: the limiting block 4089 has a contact surface 40891 and a limiting surface 40892 on the side near the connecting platform 4081, and the contact surface 40891 and the limiting surface 40892 are arranged vertically.

[0066] In the above structure, the contact surface 40891 and the limiting surface 40892 are arranged perpendicularly, so that when the card holder 4088 drives the limiting card block 4089 to clamp the screen body 5, the outer wall of the contact surface 40891 is in contact with the side wall of the screen body 5, while the outer wall of the limiting surface 40892 is in contact with the vertical surface of the side wall of the screen body 5. Therefore, when the telescopic device 4086 drives the slide rod 4085 through the connecting plate 4087, the slide rod 4085 drives the limiting card block 4089 through the card holder 4088. When block 4089 clamps the screen body 5, the contact surface 40891 only needs to be in contact with the side wall of the screen body 5. During the process of the detection robotic arm 4 moving the screen body 5 through the clamping arm 408, the downward gravity of the screen body 5 is applied to the limiting block 4089 through the limiting surface 40892. The limiting block 4089 rotates under the force, so that the contact surface 40891 squeezes the side wall of the screen body 5, thereby keeping the limiting block 4089 clamping the screen body 5.

[0067] The working principle is as follows: the detection robotic arm 4 drives the clamping arm 408 to move. Through the six-axis rotation of the detection robotic arm 4, the detection robotic arm 4 can drive the clamping arm 408 to directly clamp the screen body 5 on the storage table, and drive the screen body 5 directly to the bottom of the capacitive stylus 210, so as to realize the detection of the screen body 5 by the capacitive stylus 210. By setting the clamping arm 408 to directly clamp the screen body 5, the process of the touch detection component 2 and the image acquisition component 3 detecting the screen body 5 can be directly detected on the clamping arm 408.

[0068] Specifically, by pre-setting the length and width data of the screen body 5 and the position data of the plug-in female 501 on the outer wall of the screen body 5 in the control device, the screen body 5 achieves negative pressure adsorption through the rubber adsorption seat 40816.

[0069] During the movement of the robotic arm 4, the telescopic device 4086 drives the sliding rods 4085 via the connecting plate 4087. This causes the two sets of sliding rods 4085 to clamp the screen body 5 via the limiting block 4089, thus canceling the negative pressure adsorption of the rubber adsorption seat 40816 on the screen body 5. At the same time, the two sets of sliding rods 4085 move the screen body 5 left and right via the limiting block 4089, thereby aligning the positions of the male connector 40815 and the female connector 501. The telescopic device 40814 then drives the male connector 40815 to connect with the female connector 501, thereby enabling the screen body 5 to achieve data connection and display the image.

[0070] The detection robotic arm 4 clamps the screen body 5 through the clamping arm 408 and moves it to the bottom of the capacitive stylus 210. The touch detection component 2 drives the capacitive stylus 210 to move along the X and Y axes, thereby enabling the capacitive stylus 210 to perform touch detection on the screen body 5. While the capacitive stylus 210 is detecting the screen body 5, the camera 306 detects and collects the real-time image of the screen body 5. The collected data is matched in real time through the cloud to obtain the detection result of the capacitive stylus 210 on the screen body 5.

[0071] With the mating surface 40891 and the limiting surface 40892 arranged perpendicularly, when the card holder 4088 drives the limiting block 4089 to clamp the screen body 5, the outer wall of the mating surface 40891 is mated with the side wall of the screen body 5, while the outer wall of the limiting surface 40892 is mated with the vertical surface of the side wall of the screen body 5. Therefore, when the telescopic device 4086 drives the sliding rod 4085 through the connecting plate 4087, causing the sliding rod 4085 to drive the limiting block 4089 through the card holder 4088, the limiting block 40892 is clamped. When clamping the screen body 5, the contact surface 40891 only needs to be in contact with the side wall of the screen body 5. During the process of the detection robot arm 4 moving the screen body 5 through the clamping arm 408, the downward gravity of the screen body 5 is applied to the limiting block 4089 through the limiting surface 40892. The limiting block 4089 rotates under the force, so that the contact surface 40891 squeezes the side wall of the screen body 5, thereby keeping the limiting block 4089 clamping the screen body 5.
