Description

Technical Field

[0001] The present invention relates to the technical field of display screen power connection test equipment, in particular to an automatic plugging and unplugging device for display screen cables. Background Art

[0002] A display screen is a tool that displays electronic files on a screen via a specific transmission device. Display screens are important components of various electronic devices, such as laptops, tablets, car displays, and mobile phones. After production, displays need to be powered on to test whether they meet usage requirements. During testing, the display cables and cable connectors must be connected to a test circuit. Currently, displays are mostly tested using a manual plug-in method. This involves the operator opening a cable connector or a power plug protective cover, then holding the display cable in one hand and the power plug in the other. After plugging in, the cable protective cover is fastened. Operators experience severe fatigue after working for long periods of time, which can damage the cables, cable connectors, or power plugs, artificially increasing the number of defective displays. Furthermore, the manual plug-in testing method is inefficient, making it unsuitable for large-scale production of displays. Summary of the Invention

[0052] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0053] like Figures 1 to 10 As shown, an automatic plugging and unplugging device for display screen cables of the present invention includes: a machine 1, a loading component, a visual sensing module 6, a plug-in component and a flip-cover component.

[0054] Several positioning blocks 2 are provided in the middle position of the machine 1, and the positioning block 2 is used to position the power plug 3 to be plugged in; the loading component has a display screen positioning part 4 and a material picking robot 5, both of which are provided on the machine 1, the display screen positioning part 4 is used to position the display screen 7 to be detected, and the material picking robot 5 is used to grab the display screen 7 on the display screen positioning part 4 and drive it to move on the machine 1; the visual sensing module 6 is provided on the machine 1 and is located on the side of the positioning block 2, and the visual sensing module 6 is electrically connected to the material picking robot 5; the plug-in component is movably provided on the machine 1 and electrically connected to the visual sensing module 6, and the plug-in component is used to connect or disconnect the power plug 3 and the display screen 7; the flip-up component is movably provided on the plug-in component, and the flip-up component is used to switch the display screen 7 and / or the cable protection cover 9 on the power plug 3.

[0055] During operation, the material-grabbing robot 5 first grabs the display screen 7 placed on the display screen positioning part 4 and moves it above the visual sensing module 6. The visual sensing module 6 starts to take pictures of the bottom of the display screen 7 to record the position of the soft cable 8 at the bottom of the display screen 7 and the display screen connector 10. The visual module transmits the taken pictures to the material-grabbing robot 5 and the plug-in component. After receiving the information, the plug-in component drives the flip-up component to open the cable protection cover 9 on the display screen 7 and / or the power plug 3. Then the plug-in component grabs the power plug 3 on the positioning block 2 and plugs it with the display screen 7. After the plug-in is completed, the flip-up component closes the cable protection cover 9 on the display screen 7 and / or the power plug 3 to complete the connection between the display screen 7 and the power plug 3. After the display screen 7 is powered on and tested, the flip-up component opens the cable protection cover 9 on the display screen 7 and / or the power plug 3 again to disconnect the display screen 7 from the power plug 3. Finally, the robot puts the display screen 7 into the next process and grabs another display screen 7 to repeat the above process, thereby completing the power-on test process for all produced display screens 7. And as Figure 2 As shown, when the display screen 7 has only a single display connector 10 without a cable protection cover 9, this solution can complete the power connection operation of the display screen 7 using only the loading assembly, visual sensing module 6, and plug assembly, without the need for a flip cover assembly. The automatic plugging and unplugging device in this solution can achieve power connection detection for display screens 7 of various sizes by adjusting the size of the display screen positioning portion 4 and the movement position of the material retrieving robot 5, loading assembly, and plug assembly. This expands the application scenarios of the automatic plugging and unplugging device in this solution.

[0056] Furthermore, the plug-in assembly includes: a first linear module 11 and a second linear module 12 that are movable in horizontal and vertical directions and are arranged above the machine 1; a power plug clamping piece 13 that is detachably connected to the first linear module 11, and the power plug clamping piece 13 is used to clamp the power plug 3; a flexible cable clamping piece 14 that is detachably connected to the second linear module 12, and the flexible cable clamping piece 14 is used to grab the flexible cable 8 on the display screen 7.

[0057] The linear module is also called linear module, rectangular coordinate robot, linear slide, etc. It is an automation upgrade unit following the linear guide, linear motion module, and ball screw linear transmission mechanism. The linear and curved motion of the load can be achieved through the combination of various units, making the automation of light loads more flexible and the positioning more precise. A first linear module 11 and a second linear module 12 are provided, and the power plug clamping part 13 and the soft cable clamping part 14 are respectively provided on the first linear module 11 and the second linear module 12, so that the automatic plugging equipment of this scheme can clamp the power plug 3 and the soft cable 8 on the display screen 7 more conveniently and quickly, and thus complete the plug-in detection process of the display screen 7 more quickly. The detachable connection between the power plug clamping part 13 and the soft cable clamping part 14 and the first linear module 11 and the second linear module 12 can be achieved by a threaded connection, that is, on the first linear module 11 and the second linear module 12. A threaded hole is provided on the wire module 12, and a bolt through hole is provided on the power plug clamping member 13 and the soft cable clamping member 14, and the power plug clamping member 13 and the soft cable clamping member 14 are respectively connected to the first linear module 11 and the second linear module 12 by bolts. The detachable connection between the power plug clamping member 13 and the soft cable clamping member 14 and the first linear module 11 and the second linear module 12 can facilitate the disassembly and assembly of the power plug clamping member 13 and the soft cable clamping member 14, and facilitate the replacement of different power plug clamping members 13 and soft cable clamping members 14 when different power plugs 3 are installed on the display screen 7.

[0058] Furthermore, the power plug clamping member 13 includes: a first fixed block 15; a first cylinder 16, which is connected to the first fixed block 15; two first movable blocks 17 movably arranged at the output end of the first cylinder 16, the first cylinder 16 is used to drive the two first movable blocks 17 to move away from or approach each other, and at least one side opposite to the first movable block 17 extends outward toward the side wall away from the first movable block 17 to form a clamping block 18, and at least one first clamping groove 19 is provided at the lower part of the power plug 3, and the clamping block 18 is movably inserted into the first clamping groove 19.

[0059] During operation, the first linear module 11 drives the first fixed block 15 to move and drives the first cylinder 16 to move to a preset position. Then, the first cylinder 16 drives the two first movable blocks 17 to approach each other to clamp the power plug 3 on the positioning block 2 between the two first movable blocks 17. During the clamping process, the clamping block 18 provided on the first movable block 17 is inserted into the first clamping groove 19 provided at the lower part of the power plug 3, so that the power plug clamping member 13 can grasp the power plug 3 more firmly.

[0060] Preferably, when the power plug 3 is connected Figure 4When only a terminal head and a connecting wire are shown, the power plug clamping member 13 includes: a second fixed block 20; a second cylinder 21, which is horizontally connected to the second fixed block 20; two second movable blocks 22 movably provided at the output end of the second cylinder 21, the second cylinder 21 is used to drive the two second movable blocks 22 to move away from or closer to each other, and a second clamping groove 23 is provided on the opposite side of the two second movable blocks 22. A connecting wire is connected to the power plug 3, and the connecting wire is movably inserted into the second clamping groove 23.

[0061] During operation, the first linear module 11 drives the second fixed block 20 to move and drives the second cylinder 21 to move to a preset position. Then the second cylinder 21 drives the two second movable blocks 22 to approach each other to clamp the power plug 3 on the positioning block 2 between the two second movable blocks 22. During the clamping process, the second clamping groove 23 provided on the second movable block 22 can clamp the connecting wire in the two second clamping grooves 23, thereby making the power plug clamping member 13 grasp the power plug 3 more firmly.

[0062] Furthermore, the flip cover assembly includes: a third cylinder 24, which is horizontally connected to the second cylinder 21; a connecting block 25, which is connected to the output end of the third cylinder 24; a first toggle block 26, which is detachably connected to the connecting block 25. When the third cylinder 24 drives the connecting block 25 to move, it can drive the first toggle block 26 to move against the cable protection cover 9 on the power plug 3.

[0063] like Figure 3 As shown, when a cable protection cover 9 is provided on the power plug 3, the cable protection cover 9 needs to be opened before connecting the power plug 3 to the display screen 7, and the cable protection cover 9 needs to be closed after the power plug 3 is connected to the display screen 7. Therefore, the flip cover assembly in this solution is provided with a first toggle block 26 for toggling the cable protection cover 9 open and closed. After the power plug clamping member 13 clamps the power plug 3, the third cylinder 24 drives the first toggle block 26 to move toward the direction close to the cable protection cover 9 and toggle the cable protection cover 9 to open. After the power plug 3 and the display screen 7 are connected, the third cylinder 24 drives the first toggle block 26 to move in the opposite direction to close the cable protection cover 9.

[0064] Further, such as Figure 1 、 Figure 5 and Figure 6As shown, the soft cable clamping member 14 includes: a third fixed block 27; a fourth cylinder 28, which is connected to the third fixed block 27; an intermediate fixed block 29, which is fixed to the front end of the fourth cylinder 28, and two fixed columns 30 are provided on the intermediate fixed block 29; two third movable blocks 31 are movably arranged at the output end of the fourth cylinder 28, and the two third movable blocks 31 are detachably connected with a pressing block 32, and the fourth cylinder 28 is used to drive the two third movable blocks 31 to move closer to or away from each other, and when the fourth cylinder 28 drives the two third movable blocks 31 to move closer to each other to a preset position, the pressing block 32 moves to the top of the fixed column 30, and a limiting space for fixing the soft cable 8 on the display screen 7 is formed between the pressing block 32 and the fixed column 30.

[0065] After the power plug clamping member 13 clamps the power plug 3 on the positioning block 2 and opens the cable protection cover 9 on the power plug 3 through the flip cover assembly, the first linear module 11 moves it to the predetermined position, and the second linear module 12 moves the fourth cylinder 28 and the intermediate fixed block 29 to the bottom of the display screen 7 through the third fixed block 27. Then, the fourth cylinder 28 drives the pressing block 32 on the third moving block 31 to press the soft cable 8 on the display screen 7 into the limited space, and then the first linear module 11 and the second linear module 12 move the fourth cylinder 28 and the intermediate fixed block 29 to the bottom of the display screen 7. Driven by the group 12, the flexible cable 8 is plugged into the power plug 3 with the cable protection cover 9 already opened. Finally, the third cylinder 24 drives the first toggle block 26 to move to close the cable protection cover 9, thereby completing the connection between the flexible cable 8 and the power plug 3. After the power connection detection of the display screen 7 is completed, the third cylinder 24 drives the first toggle block 26 to move to open the cable protection cover 9. Finally, the second linear module 12 drives the flexible cable 8 and the power plug 3 away from each other through the pressing block 32 to disconnect the flexible cable 8 from the power plug 3.

[0066] Furthermore, first vacuum suction cups 33 are movably provided on both sides of the middle fixed block 29 .

[0067] The flexible flat cable 8 on the display screen 7 will be at an inconsistent height at the bottom of the display screen 7 each time when the material-retrieving robot 5 drives the display screen 7 to move. This will cause difficulties for the flexible flat cable clamping member 14 to clamp the flexible flat cable 8. Therefore, in this solution, a first vacuum suction cup 33 is movably provided on both sides of the middle fixed block 29. After the second linear module 12 drives the third fixed block 27 to move to the preset position by capturing the position of the flexible flat cable 8 through the visual sensing module 6, the second linear module 12 first lifts the third fixed block 27 to move the third fixed block 27 to the preset position. The first vacuum suction cup 33 is attached to the flexible flat cable 8 to fix its position, and then the fourth cylinder 28 drives the two third movable blocks 31 to move and clamp the flexible flat cable 8 into the limited space. The provision of the first vacuum suction cup 33 makes it easier for the two third movable blocks 31 to grasp the flexible flat cable 8. When the flexible flat cable 8 is clamped in the limited space, the first vacuum suction cup 33 is attached to the flexible flat cable 8 and drives the flexible flat cable 8 to move downward, causing the connector of the flexible flat cable 8 to tilt upward, thereby making it easier to connect the flexible flat cable 8 to the power plug 3. Preferably, the movement of the first vacuum suction cup 33 on both sides of the middle fixed block 29 can be driven by a cylinder, a motor, or other transmission component.

[0068] Further, such as Figure 6 As shown, the flip cover assembly includes: a fifth cylinder 34, which is connected to the middle fixed block 29 in the vertical direction; a second toggle block 35, which is connected to the output end of the fifth cylinder 34, and the fifth cylinder 34 is used to drive the second toggle block 35 to move in the vertical direction.

[0069] When the power plug 3 is connected to the display screen connector 10 at the lower part of the display screen 7 and a cable protection cover 9 is provided, after the first linear module 11 drives the power plug clamping member 13 to grab the power plug 3, the second linear module 12 drives the fifth cylinder 34 to move by driving the intermediate fixed block 29. After the fifth cylinder 34 moves to the preset position, the fifth cylinder 34 drives the second toggle block 35 to move upward in the vertical direction. Then, the second linear module 12 drives the second toggle block 35 to push the cable protection cover 9 by driving the fifth cylinder 34 to move, so that the display screen connector 10 on the display screen 7 is exposed to the outside, and then when the first linear module 11 drives the power plug clamping member 13 to move, the power plug 3 on the power plug clamping member 13 can be inserted into the display screen connector 10.

[0070] Further, such as Figure 4 and Figure 9As shown, the end of the material-retrieving robot 5 is provided with: a fixed seat 36, with at least two guide sleeves 37 evenly distributed around the circumference of the fixed seat 36; a second vacuum suction cup 38 corresponding to the guide sleeve 37 one by one, which is movably inserted in the guide sleeve 37; a spring 39, which is sleeved on the outer wall of the second vacuum suction cup 38, with the upper end of the spring 39 abutting against the lower end of the guide sleeve 37, and the lower end of the spring 39 abutting against the second vacuum suction cup 38.

[0071] During operation, the material-retrieving robot 5 drives the fixed seat 36 to move to the top of the display screen positioning part 4 and then moves downward in the vertical direction, so that the second vacuum suction cup 38 is tightly attached to the display screen 7 and the display screen 7 is adsorbed on the fixed seat 36. The spring 39 which is sleeved on the outside of the second vacuum suction cup 38 and presses against the second vacuum suction cup 38 and the guide sleeve 37 can reduce the pressure of the second vacuum suction cup 38 on the display screen 7 when the second vacuum suction cup 38 is pressed on the display screen 7, thereby preventing the second vacuum suction cup 38 from damaging the display screen 7.

[0072] Furthermore, a sixth cylinder 40 is vertically provided on the fixing seat 36 , a moving member 41 is provided at the output end of the sixth cylinder 40 , and a plurality of buffer blocks 42 are connected to the lower end of the moving member 41 .

[0073] When the second vacuum suction cup 38 adsorbs the display screen 7 , the sixth cylinder 40 drives the buffer block 42 to stick to the upper end of the display screen 7 to prevent the display screen 7 from tilting during the grasping process.
