Description

Technical Field

[0001] The present invention relates to the technical field of special operation robots, and in particular to an automatic maintenance robot for an LED display screen. Background Art

[0002] Currently, LED displays are commonly waterproofed by applying sealant to the joints of the cabinet. This effectively prevents water from entering the LED display panels, thus ensuring proper circuit operation. However, in practice, LED displays are often subject to the effects of natural environmental factors such as wind and sun. Over time, the sealant gradually ages, significantly weakening its sealing and waterproofing properties, increasing the risk of water intrusion into the LED display. To address this issue, existing repair methods rely primarily on manual labor, with maintenance personnel using tools to remove the aged sealant and apply new sealant in its place to restore the LED display's waterproof performance.

[0003] However, the drawbacks of manually applying sealant to repair sealants are: First, the labor intensity is high, requiring workers to hold tools for long periods of time, repeatedly scraping and applying, which consumes a lot of physical strength and energy, easily leading to fatigue, thus affecting work efficiency and quality.

[0026] See also Figure 1 and Figure 2 An embodiment of the present invention provides an automatic LED display screen repair robot for use in LED display screen repair operations. The LED display screen includes a housing and an LED display panel mounted within the housing. A first sealant is applied to the joints of the housing. The automatic LED display screen repair robot includes: a moving mechanism 10; a glue removal mechanism 20 connected to the moving mechanism 10 and configured to remove the first sealant attached to the housing; and a glue application mechanism 30 connected to the moving mechanism 10 and configured to apply a second sealant to the joints of the housing. The housing is typically made of metal.

[0027] As can be understood, the present invention provides a specialized robot for removing a first sealant from a housing and attaching a second sealant to the housing. Specifically, by moving a moving mechanism 10 across a contact surface, the glue removal mechanism 20 and glue application mechanism 30 are precisely transported to the housing joints. The glue removal mechanism 20 removes the aged first sealant, while the glue application mechanism 30 applies fresh second sealant to the housing joints, thereby refreshing the sealant and restoring the waterproof performance of the LED display, while reducing labor costs.

[0028] In this embodiment, the automatic maintenance robot for LED display screen moves the moving mechanism 10 on the contact surface to accurately transport the glue removal mechanism 20 and the glue application mechanism 30 to the joint of the box body. The glue removal mechanism 20 removes the aged first sealant, and the glue application mechanism 30 applies the new second sealant to the joint of the box body, thereby updating the sealant and restoring the waterproof performance of the LED display screen. The use of the automatic maintenance robot for LED display screen reduces labor costs and also reduces the labor intensity of workers.

[0029] In some embodiments, the moving mechanism 10 includes: a driving component 14, and a first base body 11, a second base body 12, and a third base body 13 arranged in sequence along the front and rear directions of the LED display automatic maintenance robot, the glue removal mechanism 20 is arranged on the first base body 11, and the glue application mechanism 30 is arranged on the third base body 13, and the driving component 14 is used to drive the first base body 11 and the third base body 13 to move closer to or away from each other.

[0030] Further, such as Figure 3 As shown, the mobile mechanism 10 also includes: a first adsorption foot 112, a second adsorption foot 132 and a rotating adsorption foot 123. The first adsorption foot 112 is connected to the bottom side of the first base body 11, the second adsorption foot 132 is connected to the bottom side of the third base body 13, and the rotating adsorption foot 123 is connected to the bottom side of the second base body 12; the first adsorption foot 112, the second adsorption foot 132 and the rotating adsorption foot 123 can form or release negative pressure adsorption with the contact surface, and the rotating adsorption foot 123 can also rotate when forming negative pressure adsorption with the contact surface to drive the mobile mechanism 10 to rotate in a direction perpendicular to the contact surface, thereby changing the moving direction of the LED display automatic maintenance robot.

[0031] It is understood that the mobile mechanism 10 of this embodiment is composed of a drive assembly 14, a first base 11, a second base 12, a third base 13, and a first suction foot 112, a second suction foot 132, and a rotating suction foot 123. The drive assembly 14 controls the relative distance between the first base 11 and the third base 13, thereby driving the movement of the entire LED display automatic maintenance robot on the contact surface. Specifically, in the initial state, the LED display automatic maintenance robot is in the initial position, and the first suction foot 112, the second suction foot 132, and the rotating suction foot 123 form a negative pressure adsorption with the contact surface, ensuring that the LED display automatic maintenance robot stands stably.

[0032] When the LED display automatic maintenance robot needs to move forward, the second adsorption foot 132 maintains negative pressure adsorption with the contact surface, the first adsorption foot 112 and the rotating adsorption foot 123 release the negative pressure adsorption with the contact surface, and the driving component 14 drives the first base body 11 and the third base body 13 to move away from each other. Since the second adsorption foot 132 maintains negative pressure adsorption with the contact surface at this time, the first adsorption foot 112 and the rotating adsorption foot 123 release the negative pressure adsorption with the contact surface, that is, the relative position of the third base body 13 and the contact surface remains unchanged, the second base body 12 and the first base body 11 move toward the front of the LED display automatic maintenance robot, and when the driving component 14 drives the first base body 11 and the third base body 13 to move away from each other to the preset position, the first adsorption foot 112, the second adsorption foot 132 and the rotating adsorption foot 123 are all in contact with the contact surface. The contact surface forms negative pressure adsorption; then, the first adsorption foot 112 maintains negative pressure adsorption on the contact surface, while the second adsorption foot 132 and the rotating adsorption foot 123 release negative pressure adsorption on the contact surface. The drive assembly 14 drives the first base 11 and the third base 13 closer together. Since the first adsorption foot 112 maintains negative pressure adsorption on the contact surface, the second adsorption foot 132 and the rotating adsorption foot 123 release negative pressure adsorption on the contact surface. That is, the relative position of the first base 11 and the contact surface remains unchanged. The second base 12 and the third base 13 move toward the front of the LED display automatic maintenance robot. When the drive assembly 14 drives the first base 11 and the third base 13 closer together to the preset position, the first adsorption foot 112, the second adsorption foot 132, and the rotating adsorption foot 123 all form negative pressure adsorption on the contact surface. At this point, the forward stroke movement of the LED display automatic maintenance robot proposed in this embodiment is completed.

[0033] When the LED display screen automatic maintenance robot needs to turn, the first and second suction feet 112 and 132 release their negative pressure suction on the contact surface, while the rotating suction foot 123 maintains negative pressure suction on the contact surface. At this point, the rotating suction foot 123 drives the mobile mechanism 10 to rotate perpendicular to the contact surface, changing the direction of travel of the LED display screen automatic maintenance robot. When the rotation reaches the desired forward direction of the LED display screen automatic maintenance robot, the rotating suction foot 123 stops driving the mobile mechanism 10 to rotate. The first, second, and rotating suction feet 112 and 132, respectively, all maintain negative pressure suction on the contact surface, ensuring that the LED display screen automatic maintenance robot stands stably. At this point, the turning stroke movement of the LED display screen automatic maintenance robot proposed in this embodiment is completed.

[0034] It should be noted that in this embodiment, negative pressure suction is used to establish a connection between the automatic LED display screen repair robot and the contact surface, thereby enabling the automatic LED display screen repair robot to move on the contact surface. However, in other embodiments, the mobile mechanism 10 can also be an aircraft, which drives the glue removal mechanism 20 and the glue application mechanism 30 to move to the glue removal and glue application stations. The mobile mechanism 10 can also establish a connection between the automatic LED display screen repair robot and the contact surface through magnetic suction, which will not be detailed here.

[0035] like Figure 4 As shown, in some embodiments, the drive assembly 14 includes: a first drive motor 141, a first transmission rod 146, and a transmission assembly for transmitting the output power of the first drive motor 141 and rotating the first transmission rod 146; wherein, the first transmission rod 146 includes a middle portion 1463, and a first threaded portion 1461 extending axially along the front end of the middle portion 1463 and a second threaded portion 1462 extending axially along the rear end of the middle portion 1463, the middle portion 1463 is rotatably connected to the second base body 12 along the front and rear directions of the LED display automatic maintenance robot, the first threaded portion 1461 is threadedly engaged with the first threaded hole opened in the first base body 11, and the second threaded portion 1462 is threadedly engaged with the second threaded hole opened in the second base body 12; wherein, the thread directions of the first threaded portion 1461 and the second threaded portion 1462 are opposite.

[0036] It is understood that when the first drive motor 141 is running, it transmits power to the first transmission rod 146 through the transmission assembly, causing it to rotate. Because the first threaded portion 1461 and the second threaded portion 1462 of the first transmission rod 146 have opposite thread directions, when the first transmission rod 146 rotates, the first seat body 11 and the third seat body 13, which are threadedly engaged with it, will produce relative movement, thereby moving closer to or farther away from each other.

[0037] Furthermore, two first transmission rods 146 are provided, and the transmission assembly includes an output wheel 142, a first synchronous wheel 144, a second synchronous wheel 145 and a synchronous belt 143; the output wheel 142 is connected to the power output end of the first drive motor 141; the second base body 12 is respectively provided with a first empty slot 121 and a second empty slot 122 at the places where the two first transmission rods 146 pass through, the first synchronous wheel 144 is located in the first empty slot 121 and is coaxially connected to the middle part 1463 of one first transmission rod 146, the second synchronous wheel 145 is located in the second empty slot 122 and is coaxially connected to the middle part 1463 of the other first transmission rod 146; the output wheel 142, the first synchronous wheel 144, and the second synchronous wheel 145 are connected through the synchronous belt 143.

[0038] In this embodiment, when the first drive motor 141 is activated, its power output drives the output wheel 142 to rotate. The rotating output wheel 142 drives the first and second synchronous wheels 144, 145 to rotate synchronously via the synchronous belt 143. Because the first and second synchronous wheels 144, 145 are coaxially connected to the intermediate portions 1463 of the two first transmission rods 146, their rotation drives the two first transmission rods 146 to rotate synchronously, ensuring consistency between the two first transmission rods 146 and thus coordinated movement of the first and third base bodies 11, 13. It should be noted that the two first transmission rods 146 share the task of power transmission. Compared to a single first transmission rod 146, this allows for more balanced power transmission to the first and third base bodies 11, 13, reducing structural deformation or excessive wear that could result from concentrated power at a single point, thereby improving the stability and reliability of the entire transmission system. Furthermore, the first and second empty slots 121, 122 are provided to ensure a rational layout and efficient operation of the transmission components. Two first transmission rods 146 pass through the second base body 12, and the empty groove provides installation space for the transmission rods, while ensuring that the first synchronous wheel 144 and the second synchronous wheel 145 can be connected to the corresponding transmission rods to achieve power transmission and integration, forming a complete transmission chain.

[0039] In some embodiments, the second base body 12 is an axisymmetric structure. The first slot 121 and the second slot 122 are symmetrical about the axis of symmetry of the second base body 12 , and the two first transmission rods 146 are also symmetrical about the axis of symmetry of the second base body 12 .

[0040] like Figure 2 、 Figure 5 and Figure 6 As shown, in some embodiments, the adhesive removal mechanism 20 includes a first operating assembly and an adhesive removal scraper 24. The first operating assembly is connected to the top side of the first base 11, and the adhesive removal scraper 24 is connected to the first operating assembly. The first base 11 is provided with a first operating slot 111, and the first operating assembly is used to drive the adhesive removal scraper 24 to move within the range of the first operating slot 111. Through the precise control of the first operating assembly, the adhesive removal scraper 24 can quickly and stably remove aged sealant, significantly improving adhesive removal efficiency and shortening maintenance operation time.

[0041] Furthermore, the first operating component includes: a first moving device, a second moving device 25 and a vibration motor 27. The first moving device includes a first moving end that can be moved along the left and right directions of the LED display automatic maintenance robot, and the second moving device 25 includes a second moving end that can be moved along the up and down directions of the LED display automatic maintenance robot; the second moving device 25 is connected to the first moving end, the glue removal scraper 24 is connected to the second moving end, and the vibration motor 27 is connected to the glue removal scraper 24.

[0042] In some embodiments, the first movable device includes a second drive motor 21, a second transmission rod 22, and a first slider 23. The second transmission rod 22 is rotatably mounted on the upper side of the first base 11 along the left-right direction of the LED display automatic maintenance robot. The power output end of the second drive motor 21 is connected to the second transmission rod 22. The first slider 23 is threadedly connected to the second transmission rod 22. The second movable device 25 is connected to the first slider 23, that is, the first slider 23 is the first movable end of the first movable device. The first movable device also includes a first guide rod, which is fixedly mounted on the upper side of the first base 11 along the left-right direction of the LED display automatic maintenance robot. The first slider 23 is also slidably connected to the first guide rod. In other embodiments, the first movable device can also be a linear motor. The first movable end is the mover of the linear motor.

[0043] In some embodiments, the second moving device 25 includes a cylinder, a cylinder body of the cylinder is connected to the first moving end, and the retracted end of the cylinder is the second moving end.

[0044] In some embodiments, the vibration motor 27 is a shell vibration motor 27 , which relies on the vibration of the motor shell to drive the adhesive removal scraper 24 to vibrate.

[0045] In this embodiment, the first movable end that moves left and right provides the degumming scraper 24 with a wide range of lateral movement capabilities, allowing it to cover a wider area of the cabinet joint, ensuring that the aged first sealant can be completely removed. Relying on the second movable end that moves up and down, the degumming scraper 24 has a more precise longitudinal adjustment capability. According to the degree of aging and attachment position of the first sealant, the contact force and angle between the degumming scraper 24 and the cabinet joint can be flexibly adjusted to ensure the degumming effect. The vibration motor 27 is connected to the degumming scraper 24, so that the degumming scraper 24 has a high-frequency vibration function. The vibration energy is transmitted to the degumming scraper 24, which can destroy the adhesion between the sealant and the cabinet, reduce the friction resistance between the degumming scraper 24 and the sealant, improve the degumming efficiency, reduce residue, and maintain an efficient removal effect even in the face of stubborn first sealant.

[0046] In some embodiments, the first operating assembly further includes a first swing mechanism 26, through which the adhesive scraper 24 is connected to the second movable end. The first swing mechanism 26 is used to adjust the tilt angle of the adhesive scraper 24 relative to the vertical direction of the LED display automatic repair robot. In this embodiment, the first swing mechanism 26 can adjust the tilt angle of the adhesive scraper 24 by rotating or swinging to accommodate different cabinet shapes.

[0047] It is understandable that during the glue removal process, the first swing device 26 can dynamically fine-tune the angle of the glue removal scraper 24 to ensure the optimal contact state, and the vibration motor 27 makes the glue removal scraper 24 vibrate at a high frequency to remove the first sealant.

[0048] like Figure 2 、 Figure 7 and Figure 8 In some embodiments shown, the glue application mechanism 30 includes a second operating assembly and a glue gun 34. The second operating assembly is connected to the top side of the third base 13. The glue gun 34 is filled with a second sealant and is connected to the second operating assembly. The third base 13 is provided with a second operating slot 131. The second operating assembly is used to drive the glue gun 34 to move within the second operating slot 131.
