Description

Technical Field

[0001] This invention relates to the field of assembly robot technology, specifically to a rapid assembly industrial robot for smart screens. Background Technology

[0002] Currently, large-scale smart displays are widely used in commercial advertising, conference systems, command and dispatch, and stage demonstrations. Their installation and splicing process is usually completed manually or by semi-automatic machinery. Due to the large size and weight of the screens and the extremely small gap requirements between the splices, existing assembly methods still have significant shortcomings in terms of positioning accuracy, clamping stability, and assembly efficiency.

[0003] In existing technologies, common screen assembly robots or robotic arms typically use fixed clamps or simple motorized sliding rail structures to hold and move screen modules. For example, some assembly mechanisms use single-sided grippers or independent pneumatic clamps for clamping and positioning. This structure is prone to clamping offset or left-right asynchrony when splicing multiple modules, causing the screen to fail to maintain center alignment during assembly, resulting in uneven or misaligned seams, affecting the overall display effect and installation accuracy.

[0004] Furthermore, existing clamping mechanisms mostly rely on rigid mechanical clamping methods. When there are slight errors on the screen surface or edges, rigid clamps can easily cause indentations or damage to the screen. Some solutions attempt to use rubber pads or elastic contact surfaces to buffer the pressure, but their clamping force is limited, making it difficult to balance stability and safety in high-precision splicing.

[0005] Traditional mechanical clamping structures generally suffer from two technical problems during screen handling and positioning: First, it lacks automatic centering and synchronous adjustment capabilities. Most existing systems use a deflection-driven clamping mechanism, and the deflection clamps on both sides are difficult to accurately position and insert into the screen edge seam, requiring manual alignment, which is complicated and inefficient. Secondly, the clamping force cannot be adaptively adjusted. Due to differences in screen thickness and edge structure, the fixing claws often cause uneven clamping during clamping, affecting assembly stability.

[0006] In addition, in terms of clamping and anti-slip, most existing mechanical assembly devices achieve clamping by mechanical stops or fixed friction plates. The mechanical stop structure and fixed friction plate structure increase the thickness of the clamp, which cannot be adapted to the screen seam, and cannot automatically adjust the clamping force according to different assembly parts, resulting in problems such as slippage and deflection.

[0007] For the drive components of robotic arms, traditional structures often employ independent motor linear drives or rack and pinion transmissions, which are complex and costly. While some assembly robots possess angle adjustment capabilities, they lack efficient linkage transmission designs, failing to achieve circular linkage control via guide wheel discs, resulting in unstable movement and limited positioning accuracy.

[0008] In view of this, we will study and improve upon the existing problems and provide a rapid assembly industrial robot for smart screens to solve the current issues. Summary of the Invention

[0009] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0010] Therefore, the technical solution adopted in this invention is as follows: a rapid assembly industrial robot for smart screens, comprising a servo robotic arm, a positioning plate base, and a gripper assembly. The positioning plate base is fixed to the end effector of the servo robotic arm, and the positioning plate base is provided with a slide rail and a sliding plate base, the sliding plate base being able to slide along the slide rail; a rotatable guide wheel is mounted on the surface of the positioning plate base, the guide wheel being driven to rotate by a driver; an arc-shaped groove is formed on the surface of the guide wheel, and a sliding pin is provided on the surface of the sliding plate base, the sliding pin being slidably sleeved on the inner side of the arc-shaped groove.

[0011] The clamping ear assembly is fixedly installed on the surface of the slide seat. Its structure includes an ear rod, a manifold rod, several clamping tooth rods and an air expansion pad. The manifold rod is connected to an external air pump. Each clamping tooth rod is arranged along its length and has a flow channel inside that communicates with the air expansion pad. The surface of the clamping tooth rod is provided with inserting tooth ears, and the air expansion pad is embedded in the inserting tooth ears.

[0012] The adsorption assembly is mounted on the surface of the clamp assembly and includes a telescopic rod and a suction cup. The telescopic rod is extendable in the vertical direction, and the suction cup is connected to an external vacuum source.

[0013] Through the above structural combination, the present invention can realize multi-axis attitude control, automatic centering positioning, flexible limiting clamping and vacuum adsorption assisted fixation at the robot end, effectively solving the technical problems of poor synchronization and unstable clamping in large screen assembly.

[0014] In a preferred example, the servo robotic arm has a multi-axis linkage structure, with its input end electrically connected to a servo control system and its end effector mounted with a servo motor to drive the positioning plate to rotate.

[0015] Specifically, this structure enables precise adjustment of the clamping angle and position, allowing the robot to complete the alignment and splicing of screen modules in complex spaces, significantly improving assembly flexibility and operational accuracy.

[0016] In a preferred example, a slide rail is provided on the surface of the positioning plate base, and the slide plate base slides along the slide rail; a number of guide limit blocks are provided on the surfaces of the positioning plate base and the slide plate base to limit the sliding trajectory of the slide plate base.

[0017] Specifically, this structure allows the skateboard seat to slide smoothly and without deviation, enabling linear and precise adjustment of the clamping assembly and ensuring synchronization between lateral movement and center positioning.

[0018] In a preferred example, the guide wheel is a toothed disc structure, with the outer peripheral teeth meshing with the output end of the driver for transmission; an arc groove is formed on the surface of the guide wheel, and the sliding pin on the slide plate seat is slidably sleeved in the arc groove, with the two sets of arc grooves and sliding pins arranged symmetrically about the axis of the guide wheel about the origin.

[0019] Specifically, the transmission assembly can drive the slide plate to reciprocate when the guide wheel rotates, realizing the synchronous lateral movement and automatic centering movement of the clamping ear assembly, thereby ensuring the symmetrical positioning accuracy during the assembly of the large screen module.

[0020] In a preferred example, the clamping assembly includes an ear rod, a manifold rod, and several clamping teeth rods. The top of the ear rod is vertically connected to the slide plate seat. A gas channel is formed inside the manifold rod, one end of which is connected to an external air pump. Multiple clamping teeth rods are arranged equidistantly along the length direction on the surface of the clamping teeth rod. The surface of the clamping teeth rod is provided with inserting teeth ears, and an air expansion pad is embedded inside the toothed teeth rod. A flow channel connecting the manifold rod and the air expansion pad is provided inside the clamping teeth rod.

[0021] Specifically, the pneumatic structure achieves adaptive adjustment of clamping force through external air pump control. After the air pad expands, it generates lateral limiting and vertical friction enhancement effects, ensuring the stable clamping of the assembly and preventing the screen from slipping or being damaged.

[0022] In a preferred example, the air cushion includes several vertically arranged vertical tubes and horizontally arranged bulges. When gas is injected, the bulges bulge outward and are limited, while the vertical tubes expand vertically to increase friction.

[0023] Specifically, the structure achieves flexible clamping while forming a multi-point friction support surface, which stabilizes the assembled screen and prevents slippage while avoiding damage to the screen edges caused by traditional rigid clamps.

[0024] In a preferred example, the adsorption assembly includes a telescopic rod and a suction cup, which is arranged perpendicular to the slide base. The suction cup is connected to an external vacuum source via a vacuum line to provide auxiliary adsorption during clamping.

[0025] Specifically, after the adsorption component extends, it can attach the suction cup to the screen surface and form a negative pressure adhesion through vacuum adsorption. This, together with the pneumatic clamping of the clip component, effectively improves the stability of the screen during transportation and splicing.

[0026] In a preferred example, a guide limit block structure is provided between the positioning plate base and the skateboard base to limit the sliding direction and prevent deviation; the linkage between the guide wheel and the sliding pin enables the skateboard base to slide synchronously left and right.

[0027] Specifically, this design can achieve dual-sided synchronous transmission when the driver outputs from only one side, reducing error accumulation, improving lateral clamping synchronization, and achieving automatic centering positioning.

[0028] The beneficial effects achieved by this invention are as follows: 1. In this invention, the clamping ear assembly achieves lateral synchronous movement under the drive of the guide wheel disk, and the slide plate seat reciprocates smoothly along the slide rail. Through the coordinated action of the left and right clamping ear assemblies, the screen to be assembled can be automatically centered or clamped, ensuring assembly accuracy and alignment consistency.

[0029] 2. In this invention, the air pad expands and deforms after being inflated. Its lateral bulges outward to form a limit, and its vertical tube expands outward along the outer edge of the screen to increase friction. Thus, it has both limiting and anti-slip functions, ensuring the stability and anti-slip properties of the screen during clamping and handling.

[0030] 3. In this invention, the guide wheel rotates under the drive of the driver, and the cooperation between the arc groove and the sliding pin enables the reciprocating lateral movement of the slide block, thereby driving the clamping ear assembly to generate synchronous displacement. This structure has a clear transmission relationship and stable operation, enabling synchronous mechanical movement and improving the control accuracy and response sensitivity of the robot's end effector.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0034] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0035] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a rapid assembly industrial robot for smart screens.

[0036] Combination Figures 1-8 As shown, the present invention provides a rapid assembly industrial robot for smart screens, including a servo robotic arm 100, a positioning plate base 200, a clamping ear assembly 300, and an adsorption assembly 400.

[0037] The servo robotic arm 100 is a multi-axis robotic arm structure, with its input end electrically connected to a servo control system for achieving multi-degree-of-freedom spatial control. A servo motor is fixedly mounted at the end of the servo robotic arm 100 to drive the positioning plate 200 to rotate, thereby adjusting the angle and posture of the end effector and achieving high-precision adjustment of the assembly position.

[0038] The positioning plate base 200 is fixedly installed at the end of the servo robotic arm 100 to support, adjust and drive the clamping ear assembly 300 to perform assembly actions.

[0039] A slide rail 201 is fixedly mounted on the surface of the positioning plate base 200. A slide plate base 210 is slidably mounted on the slide rail 201. The slide plate base 210 can reciprocate linearly along the slide rail 201 to achieve lateral fine adjustment of the clamping ear assembly 300.

[0040] A guide wheel 230 is rotatably mounted on the surface of the positioning plate base 200. The guide wheel 230 has a geared structure with teeth on its outer circumference. A driver 220 is provided on one side of the positioning plate base 200. The driver 220 is a servo driver, and its output gear meshes with the outer teeth of the guide wheel 230 for transmission. The driver 220 drives the guide wheel 230 to rotate through the rotation of its output shaft, thereby controlling the forward and reverse rotation of the guide wheel 230.

[0041] The guide wheel disk 230 has an arc-shaped groove 231 on its surface, with its two ends close to the center and outer periphery of the guide wheel disk 230, respectively. A sliding pin 211 is fixedly mounted on the surface of the slide plate base 210, and the sliding pin 211 is slidably fitted onto the inner side of the arc-shaped groove 231. The two arc-shaped grooves 231 and the sliding pin 211 are symmetrically arranged around the axis of the guide wheel disk 230. When the driver 220 drives the guide wheel disk 230 to rotate, the sliding pin 211 moves in an arc along the arc-shaped groove 231, thereby driving the slide plate base 210 to reciprocate along the slide rail 201, causing the clamping ear assembly 300 to produce lateral displacement, achieving precise adjustment and synchronous correction of the assembly position.

[0042] To prevent sliding and deviation, a number of guide limit blocks are provided on the opposing surfaces of the positioning plate base 200 and the slide plate base 210 to limit the sliding trajectory of the slide plate base 210, ensuring that the sliding process is smooth, the alignment is accurate, and no deviation or derailment occurs.

[0043] In this embodiment, the clamping ear assembly 300 is fixedly installed on the surface of the slide plate base 210, and its structure includes an ear rod 310, a manifold rod 320, and a plurality of clamping tooth rods 330 arranged on the surface of the manifold rod 320.

[0044] The top of the lug 310 is vertically connected to the bottom surface of the slide base 210, supporting the manifold rod 320 and ensuring the structural stability of the clamp assembly 300. The manifold rod 320 extends horizontally along the lug 310, and has an internal gas channel connected to an external air pump assembly. The air pump assembly controls the air pressure changes inside the manifold rod 320 through the gas channel, thereby achieving pneumatic control of the clamp assembly 300.

[0045] Several toothed rods 330 are evenly arranged along the length of the manifold rod 320. Each toothed rod 330 has a flow channel inside for connecting the manifold rod 320 and the air expansion pad 340, so that gas can be transported from the manifold rod 320 to the air expansion pad 340.

[0046] Each clamping bar 330 has a fixedly mounted toothed lug 331 on its surface. The toothed lug 331 is a thin sheet structure with grooves on its surface for mounting and positioning the air expansion pad 340. The toothed lug 331 and the clamping bar 330 are integrally formed to improve clamping strength and stability.

[0047] The air expansion pad 340 is embedded in the groove of the insert ear 331. The air expansion pad 340 is an air-expanding structure, with several vertically arranged vertical tubes 341 and horizontally arranged protrusions 342 inside, which can form synchronous expansion when gas is injected.

[0048] When the external air pump is started, compressed air enters the flow channel inside the clamping rod 330 through the manifold rod 320 and is injected into the air expansion pad 340. When the air expansion pad 340 expands, the transverse bulge 342 bulges outward and contacts the side edge of the screen to be assembled to form a limit. The vertical tube 341 bulges out along the outer edge of the screen to increase friction and achieve stable clamping and limiting positioning of the screen module.

[0049] Under normal conditions, the air pad 340 is in an uninflated state, and the insert ear 331 remains in a thin sheet shape, allowing it to be directly inserted into the splicing gap of adjacent screen modules. Through the air inflation process, the entire process from "insertion—positioning—clamping—release" can be controlled.

[0050] In this embodiment, the adsorption assembly 400 is mounted on the surface of the clamping assembly 300, and its structure includes a telescopic rod and a suction cup. The adsorption assembly 400 is arranged perpendicular to the slide base 210 and is used to adsorb and fix the assembled screen during handling or assembly.

[0051] The telescopic rod is used to adjust the extension distance and angle of the adsorption assembly 400 to accommodate large screen modules of different thicknesses and angles. The suction cup is mounted at the end of the telescopic rod, and its surface is made of a highly elastic sealing material. It is connected to an external vacuum source via a vacuum pipeline. When the vacuum source is activated, the suction cup adheres tightly to the screen surface under negative pressure, thus providing auxiliary support and fixation.

[0052] The adsorption component 400 and the clamping ear component 300 operate synchronously. The clamping ear component 300 provides clamping force, and the adsorption component 400 provides adhesion force. The two work together to ensure the stability of the assembled screen during handling, positioning and assembly.

[0053] Working principle and usage process: The present invention relates to a rapid assembly industrial robot for smart screens. It mainly achieves automatic handling, positioning, and splicing assembly of large screen modules through the coordinated action of three parts: servo robotic arm 100, positioning plate base 200, and clamping ear assembly 300.

[0054] In use, the servo robotic arm 100, driven by commands from the servo control system, drives the positioning plate 200 to perform multi-axis movements in space to achieve precise position adjustment of the target screen. The surface of the positioning plate 200 is equipped with a slide rail 201 and a sliding plate 210. The sliding plate 210 can slide back and forth along the slide rail 201 to achieve lateral fine-tuning of the clamping assembly 300, clamping the assembled parts, or centering the assembled parts before adsorption by the adsorption assembly 400. A driver 220 located on one side of the positioning plate 200 is connected to a guide wheel 230 via an output shaft. When the driver 220 is activated, the guide wheel 230 drives the sliding pin 211 to slide in an arc along the arc groove 231, thereby driving the sliding plate 210 to reciprocate along the slide rail 201, achieving precise adjustment of the clamping assembly 300's position. This mechanism allows for lateral positioning of the assembled parts, centering them in place, and further allows for clamping and handling of the assembled parts via the clamping lug assembly 300.

[0055] The clamping assembly 300 is supported by the ear rod 310. A gas channel is formed inside the manifold rod 320, connected to an external air pump system. Several clamping teeth 330 are equidistantly arranged on the surface of the manifold rod 320, each clamping tooth 331 fixedly mounted with an insert ear 331, which contains an air expansion pad 340. Before assembly, the air expansion pad 340 is in an uninflated state, and the insert ear 331 is thin, allowing it to be easily inserted into the splicing gap between adjacent screen modules. When the external air pump is started, compressed gas enters the flow channel within the clamping teeth 330 through the manifold rod 320 and is injected into the air expansion pad 340. The air expansion pad 340 expands accordingly, its lateral bulge 342 protruding outwards and contacting the edge of the screen to form a limit; simultaneously, the vertical tube 341 expands along the outer edge of the screen, increasing contact friction, thereby achieving stable clamping and positioning of the screen module.

[0056] The screen to be assembled is held by the clamping ear assembly 300 or the screen to be assembled is positioned by the adsorption assembly 400, and the screen to be assembled is transferred. When the robot end is close to the installation position of the large screen, the clamping ear assembly 300 begins to perform the clamping action.

[0057] During the clamping process, the adsorption component 400 operates synchronously. The adsorption component 400 includes a telescopic rod and a suction cup structure. The telescopic rod extends vertically, allowing the suction cup to adhere to the screen glass surface. The suction cup is connected to an external vacuum source via a vacuum tube, generating adhesion under vacuum negative pressure to achieve auxiliary adsorption and support for the screen surface. This adsorption force, combined with the air-expansion clamping force, effectively prevents the screen from slipping, shaking, or tilting during handling and splicing.

[0058] Once assembly is complete, the control system issues a pressure relief command, the air pump reverses its exhaust direction, releasing the gas inside the inflation pad 340. The bulge 342 and the vertical tube 341 return to their original positions, the gripper bar 330 releases the assembled parts, the adsorption assembly 400 simultaneously releases the vacuum adsorption, and the telescopic rod retracts to its initial position. The entire process is completed automatically, and the servo robotic arm 100 can then perform the next assembly task.
