Description

Technical Field

[0001] This invention relates to the field of automated welding technology, specifically to an intelligent welding device for the processing of smart seats. Background Technology

[0002] Currently, in the field of smart seating or office chair manufacturing, the support structure of a chair typically consists of a seat support column and multiple leg rods evenly distributed along its outer perimeter. During assembly and processing, the support column and leg rods need to be welded and fixed to form an overall support frame, thereby ensuring the stability and load-bearing capacity of the chair.

[0003] In existing production processes, welding assembly typically employs semi-automated or manual clamping methods. This involves placing the seat support column in a fixed fixture, manually clamping each support rod one by one, and then welding is completed by a welder or a simple robotic arm. These clamping structures often use rigid mechanical jaws or threaded locking mechanisms, requiring manual intervention for clamping and releasing, resulting in low loading and unloading efficiency. Furthermore, the position and angle of each support rod must be repeatedly measured and fine-tuned manually to ensure it corresponds to the welding position on the outer circumference of the support column.

[0004] Furthermore, traditional equipment often features only a single degree of freedom or a single motor drive structure, making it impossible to achieve automatic relative rotation and displacement adjustment of the support column and legs during welding. To achieve multi-point welding, manual rotation of the workpiece is often required, either manually or through additional mechanical mechanisms, increasing operation time and positioning errors. After welding, the clamping structure of the tooling still needs to be manually loosened and repositioned, limiting the processing cycle.

[0005] Furthermore, most existing welding fixtures use a flat-push or single-sided clamping structure for their clamping mechanisms, which lack automatic compensation and self-centering capabilities. This can easily lead to workpiece eccentricity or welding deformation, making it difficult to guarantee weld consistency and appearance quality. For welding scenarios involving multiple angles and multiple support legs, existing equipment lacks automated coordination and control capabilities, making it impossible to complete multi-angle welding operations in a single cycle.

[0006] In view of this, we will study and improve upon the existing problems and provide an intelligent welding device for the processing of smart seats to solve the current problems. Summary of the Invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted in this invention is: an intelligent welding device for processing smart seats, comprising a base, a bearing plate, tooling components, and a welding robotic arm. The base is equipped with a first drive motor and a second drive motor for driving, and is provided with a drive cylinder, a support rod, and a lever connecting rod for tooling clamping transmission.

[0009] The bearing plate is rotatably mounted on the base surface, and its bottom surface is linked to the first drive motor via a pulley; the top surface is provided with multiple sliding trays for positioning the support legs.

[0010] The tooling components include a turntable, a gear sleeve shaft, a clamp, and a second transmission key shaft, which are used to clamp the seat support column and drive it to rotate.

[0011] The welding robotic arm is fixed to one side of the base and is used to perform automated welding tasks.

[0012] In a preferred example, the sandwich is a cylindrical structure with an oblique conical surface on its outer periphery and a seat support column that can be inserted into its inner wall.

[0013] The outer side of the clamp is slidably installed inside the cone ring, and the bottom end is connected to the lever connecting rod through a tie rod. The lever connecting rod is pushed and deflected by the drive cylinder, causing the clamp to slide along the cone ring axis.

[0014] When the drive cylinder extends downwards, the clamping core contracts radially under the action of the annular wedge surface, thereby clamping the seat support column; when the drive cylinder retracts, the clamping core slides in the opposite direction to release the support column, realizing automatic clamping and unloading.

[0015] Specifically, through this wedge and lever combination structure, the axial thrust of the drive cylinder is converted into radial clamping force. The clamping force is uniform and the positioning is reliable, which improves the clamping accuracy and repeatability.

[0016] In a preferred example, the welding robot arm is a multi-axis servo robot arm structure with a welding head mounted at its end. The input end of the welding robot arm is electrically connected to the servo control system, and the tracking, angle adjustment, and welding operations of the weld seam can be automatically completed through programmed control.

[0017] Specifically, the robotic arm adjusts the welding trajectory in real time according to the rotational position of the bearing plate and tooling components to achieve automated continuous welding, avoid manual alignment errors, and improve weld consistency.

[0018] In a preferred example, both the first drive motor and the second drive motor adopt a servo motor structure. The first drive motor is connected to the pulley via a transmission key shaft and is used to drive the bearing plate to rotate. The second drive motor is connected to the second transmission key shaft and is used to drive the turntable and the clamp to rotate.

[0019] Specifically, the coordinated control of the two motors can realize the linkage between the rotation of the support column and the revolution of the support rod, automatically adjust the relative posture during the welding process, realize multi-angle welding, and improve the uniformity of the weld.

[0020] In a preferred example, multiple sliding trays are detachably mounted on the top surface of the bearing plate. Each sliding tray has a groove on its surface that is adapted to the support rod, and a magnetic adsorption layer is provided for workpiece fixation.

[0021] Specifically, the magnetic positioning method enables rapid loading and accurate positioning without the use of mechanical clamps. The support rods have strong positional stability, which can effectively prevent the workpiece from shifting during welding heat deformation.

[0022] In a preferred example, the turntable, the gear sleeve shaft, and the clamp are all arranged coaxially with the pulley; the driven teeth at the bottom of the turntable mesh with the second transmission key shaft, and the gear sleeve shaft is simultaneously connected to the second transmission key shaft.

[0023] Specifically, this structure enables multi-axis concentric synchronous rotation, allowing the turntable, clamping core, and clamped workpiece to rotate synchronously, eliminating runout error and improving rotational accuracy.

[0024] In a preferred example, the core surface is provided with a number of axially distributed deformation gaps, the outer peripheral inclined surface of which abuts against the annular wedge surface of the conical ring.

[0025] Specifically, when the drive cylinder pushes the pull rod down, the clamping core slides along the conical ring and contracts radially, achieving self-centering clamping of the support column. This structure, through inclined plane force transmission and deformation compensation, ensures uniform distribution of clamping force, prevents workpiece eccentricity, and improves welding stability and repeatability.

[0026] In a preferred example, one end of the lever connecting rod is connected to the output end of the drive cylinder, and the other end is connected to the bottom end of the pull rod. The middle part of the lever connecting rod is rotatably connected to the base through a support rod.

[0027] Specifically, the lever mechanism converts the linear thrust of the drive cylinder into an amplified output force, enabling rapid clamping or release of the clamping core. Through lever support and torque transmission, the clamping stroke is short, the response is fast, and the tooling response efficiency is high.

[0028] The beneficial effects achieved by this invention are as follows:

[0029] 1. In this invention, the automatic clamping and release of the tooling is realized through the linkage structure between the drive cylinder, lever connecting rod, clamping core and conical ring. Combined with the dual servo drive system, the automatic displacement and flipping of the bearing plate and turntable are realized, so that the welding tooling has the functions of automatic clamping, automatic alignment and automatic reset, which significantly improves the automation level and production efficiency of the equipment.

[0030] 2. In this invention, a wedge-type tooling structure is adopted. The outer periphery of the clamping core has a conical surface that cooperates with the annular wedge surface on the conical ring. Through the torque transmission of the drive cylinder and the lever connecting rod, the radial contraction clamping of the clamping core is achieved, so that the clamping force is evenly distributed in the radial direction. This lever amplification structure makes the transmission efficiency high, the clamping reliable, and the positioning accuracy high, significantly improving the clamping stability and repeatability of the tooling.

[0031] 3. In this invention, the first drive motor and the second drive motor are used for the revolution drive of the bearing plate and the rotation drive of the turntable, respectively. Together, they enable the indexing rotation of the seat support column and the revolution position adjustment of the support rod, thereby achieving automatic alignment and precise welding. Simultaneously, the two motors can drive synchronously, realizing dynamic displacement adjustment during the welding process. This ensures that the support column and support rod maintain the optimal welding posture at different spatial angles, improving weld quality and production integration, reducing manual intervention, and significantly improving overall welding accuracy and efficiency.

[0046] 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.

[0047] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0048] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, an intelligent welding device for the processing of smart seats.

[0049] Combination Figures 1-9 As shown, the present invention provides an intelligent welding device for processing smart seats, including a base 100, a bearing plate 200, a tooling assembly 300, and a welding robotic arm 110 fixed to one side of the base 100.

[0050] The base 100 is the main support of the equipment and is used to install various transmission components and control actuators; the bearing plate 200 is set above the base 100 and is mounted on the surface of the base 100 by a rotatable connection; the tooling assembly 300 is located in the central area of ​​the bearing plate 200 and is used to clamp and rotate the seat support column 400.

[0051] The base 100 has a first drive motor 120 and a second drive motor 130 fixedly installed on its bottom surface, which are used to drive the bearing plate 200 to revolve and the tooling assembly 300 to rotate, respectively.

[0052] The bottom surface of the bearing plate 200 is provided with a pulley 220, and the top surface of the bearing plate 200 is detachably equipped with several sliding trays 210. Each sliding tray 210 is used to place the seat support rod 410, so as to realize the multi-station arrangement of the workpiece.

[0053] A drive cylinder 140 and a support rod 142 are fixedly installed inside the base 100. A lever connecting rod 141 is rotatably mounted on the bottom end of the support rod 142. One end of the lever connecting rod 141 is movably connected to the output end of the drive cylinder 140, and the other end is connected to the pull rod 331 of the tooling assembly 300 for transmitting axial driving force. A first transmission key shaft 121 is also rotatably mounted on the inner side of the base 100. One end of the first transmission key shaft 121 is engaged with the output end of the first drive motor 120 for transmission, and the other end is connected to the pulley 220 for transmission.

[0054] The tooling assembly 300 includes a turntable 310, a gear sleeve shaft 320, a clamp 330, and a second transmission key shaft 340 rotatably mounted inside the pulley 220. The bottom surface of the turntable 310 is provided with driven teeth 311, which mesh with both ends of the gear sleeve shaft 320 for transmission. A conical ring 312 is fixedly mounted on the inner side of the turntable 310, and the clamp 330 is movably sleeved on the inner side of the conical ring 312, with its bottom end slidably sleeved on the inner side of the gear sleeve shaft 320. A pull rod 331 is rotatably mounted on the bottom end of the clamp 330, and the bottom end of the pull rod 331 is movably connected to one end of the lever connecting rod 141. Several deformation gaps are formed on the outer wall of the clamp 330, allowing it to radially deform and contract when the drive cylinder 140 is activated, thus securing the seat support column 400 in a clamped state.

[0055] With the above structural configuration, the first drive motor 120 drives the bearing plate 200 to rotate to realize the workpiece revolution, the second drive motor 130 drives the tooling assembly 300 to rotate to realize the self-rotation, and the drive cylinder 140 controls the clamping core 330 to retract and release, thereby completing the entire process of automatic clamping and welding.

[0056] This structure enables the welding equipment to achieve multi-functional integrated control that combines clamping, rotation, alignment, and welding; the rotation of the tooling and the rotation of the bearing plate can operate independently or in coordination, resulting in flexible welding angles, high repeatability, and significantly improved automated welding efficiency.

[0057] In this embodiment, the welding robotic arm 110 includes a multi-axis servo robotic arm and a welding head fixed to the end of the robotic arm. The input end of the welding robotic arm 110 is electrically connected to a servo control system, which can set the motion path and welding parameters according to the control program to realize multi-angle welding operations.

[0058] In actual operation, the welding robot arm 110 can adjust its posture in real time according to the rotation state of the bearing plate 200 and the tooling assembly 300 to keep the welding gun head always aligned with the weld position, thereby completing automatic circumferential welding, spot welding and fillet welding.

[0059] Through multi-axis servo control, the welding robotic arm 110 has high degrees of freedom and high response speed, and can be synchronized with the movement of the equipment to ensure the quality of weld formation and the stability of the welding trajectory, thus significantly improving welding accuracy.

[0060] In this embodiment, both the first drive motor 120 and the second drive motor 130 are servo motors, used to drive the rotation of the pulley 220 and the turntable 310, respectively. The drive cylinder 140 is an electric push rod structure used to drive the clamping core 330 to slide along the conical ring 312, realizing clamping or releasing actions. When the drive cylinder 140 extends, it drives the lever connecting rod 141 to deflect, which in turn moves the connecting rod 331 downward, causing the clamping core 330 to slide down along the conical ring 312. The outer circumferential conical surface of the clamping core 330 engages with the wedge surface of the conical ring 312, generating a radial inward force, thereby clamping the seat support column 400. When the drive cylinder 140 retracts, the clamping core 330 resets and releases the workpiece.

[0061] Specifically, the servo motor works in conjunction with the electric push rod to enable electronic control of clamping, rotation, and posture adjustment, which features fast response, high precision, and strong synchronization, and can meet the precision requirements of highly automated welding processes.

[0062] In this embodiment, multiple sliding trays 210 are detachably mounted on the surface of the support plate 200. The upper surface of each sliding tray 210 has an arc-shaped groove adapted to the seat support rod 410, and a magnet is located at the bottom of the groove. When the seat support rod 410 is placed on the groove, the magnetic attraction automatically achieves initial positioning and stable fixation of the workpiece. The sliding trays 210 are fixed to the support plate 200 by snaps or positioning pins, allowing for quick replacement and position adjustment according to different seat models.

[0063] Specifically, the design enables a multi-station layout, improving material loading efficiency and positioning accuracy. It also allows for flexible adjustments based on the arrangement of different workpieces, enhancing equipment versatility and production efficiency.

[0064] In this embodiment, the turntable 310, the gear sleeve shaft 320, and the clamping core 330 are arranged coaxially and form a vertical transmission shaft system with the pulley 220. The bottom surface of the turntable 310 is provided with driven teeth 311, and the gear sleeve shaft 320 is sleeved on the outside of the clamping core 330. The surface of the second transmission key shaft 340 is provided with a gear tooth structure that matches the driven teeth 311 and the gear sleeve shaft 320, so as to realize the dual-end output of power and make the turntable 310 and the clamping core 330 rotate synchronously.

[0065] The double-end gear meshing structure enables stable power transmission of the self-rotating system, ensuring that the rotation of the clamping core is consistent with the posture of the workpiece, preventing slippage and wobble during welding, and improving welding coaxiality.

[0066] In this embodiment, the core 330 has a cylindrical structure with several deformation gaps evenly distributed along its axial direction on its surface, forming an elastic segmented structure. The outer periphery of the core 330 has an inclined conical surface, and the surface of the conical ring 312 has an annular wedge surface that abuts against it. When the drive cylinder 140 actuates, the core 330 slides along the conical ring 312 and contracts radially under the action of the wedge surface, thus clamping and fixing the support column 400. During reverse drive, the core 330 returns to its original position, achieving rapid disengagement. Through the mechanical amplification effect of the conical and wedge surfaces, the axial force of the drive cylinder 140 is converted into a radial clamping force, resulting in uniform clamping, high positioning accuracy, and automatic compensation for dimensional deviations.

[0067] In this embodiment, the two ends of the lever connecting rod 141 are movably connected to the output end of the drive cylinder 140 and the bottom end of the pull rod 331, respectively, and the middle part of the lever connecting rod 141 is rotatably connected to the end of the support rod 142. When the drive cylinder 140 extends or retracts, the lever connecting rod 141 deflects around the support rod 142 as a fulcrum, converting the linear displacement of the drive cylinder 140 into the up-and-down linear motion of the pull rod 331. This lever-type transmission structure can reduce the drive load, amplify the clamping displacement, improve the mechanical efficiency and stability of the system, and at the same time reduce the electric push rod stroke, achieving a more compact installation space layout.

[0068] Working principle and usage process of this invention:

[0069] This invention relates to an intelligent welding equipment for the processing of smart seats. Through the coordinated control of the base 100, bearing plate 200, tooling assembly 300, and welding robotic arm 110, it achieves automatic positioning, clamping, and multi-angle welding operations of the seat support column 400 and the support rod 410. Its core principle lies in the linkage design of the dual-drive servo transmission system and the core deformation mechanism, which enables the tooling to achieve fully automatic motion control of clamping, rotation, revolution, and rotation, thus completing an integrated welding process.

[0070] I. Clamping and clamping stage

[0071] At the start of operation, the seat support column 400 is inserted into the inner side of the clamping core 330, with the outer circular surface of the support column 400 fitting against the inner wall of the clamping core 330. At this time, the drive cylinder 140 is activated, pushing the lever connecting rod 141 to generate a deflection motion, which in turn drives the connected pull rod 331 downwards, causing the clamping core 330 to slide axially along the conical ring 312. With the cooperation of the outer circumferential conical surface of the clamping core 330 and the annular wedge surface of the conical ring 312, the clamping core 330 radially deforms and contracts, forming a uniform internal clamping force on the support column 400, thus completing the tooling clamping. This deformation clamping action has a self-centering characteristic, automatically eliminating clamping gaps and ensuring that the support column is positioned coaxially and stably.

[0072] II. Outrigger Positioning Stage

[0073] After clamping, the operator or upstream robot places multiple support rods 410 onto the sliding tray 210. The surface of the sliding tray 210 has grooves that match the bottom of the support rods and has a magnetic adsorption function, which can quickly position and firmly fix the support rods 410, ensuring the accuracy of the welding station. Multiple sliding trays 210 on the support plate 200 can correspond to multiple support rods 410, thereby realizing simultaneous welding preparation at multiple stations.

[0074] III. Revolution and Alignment Phase

[0075] Once the tooling is clamped, the first drive motor 120 starts, driving the bearing plate 200 to rotate via the meshing of the first transmission key shaft 121 and the pulley 220. At this time, the sliding tray 210 supporting the support rod 410 revolves around the clamped support column 400 along with the bearing plate 200, achieving circumferential position adjustment between the support rod 410 and the support column 400. By precisely controlling the revolution angle through a servo system, the support rod 410 can automatically rotate to the alignment position with the welding position of the support column 400, completing the pre-welding positioning.

[0076] IV. Rotation and Attitude Adjustment Stage

[0077] After the revolution positioning is completed, the second drive motor 130 starts, and its output end drives the gear sleeve shaft 320 to rotate synchronously with the turntable 310 through the second transmission key shaft 340. The driven gear 311 meshes with the gear sleeve shaft 320, causing the clamping core 330 and the clamped support column 400 to rotate as a whole. During this process, the revolution of the support plate 200 and the rotation of the tooling clamping core 330 can operate separately or in coordination, thereby achieving precise angle adjustment of the support column 400 relative to the support rod 410. When the first drive motor 120 and the second drive motor 130 operate in coordination, a combined motion of revolution and rotation can be achieved, enabling the support column 400 and the support rod 410 to achieve a compound deflection posture, providing an ideal spatial position for multi-angle welds.

[0078] V. Welding Operation Stage

[0079] After the alignment is completed, the welding robotic arm 110 begins to move. The welding robotic arm 110 is a multi-axis servo-controlled structure. Its welding head can adjust the welding path and angle in real time according to the rotation angle of the bearing plate 200 and the tooling posture, performing precise welding on the seam between the support rod 410 and the support column 400. The servo control system of the multi-axis robotic arm can compensate based on real-time angle data of revolution and rotation, ensuring that the welding torch is always perpendicular or tilted towards the weld position, thereby guaranteeing uniform weld formation and full weld points, significantly improving welding consistency.

[0080] VI. Reset and Unloading Stage

[0081] After welding is completed, the control system sends a reverse command to the drive cylinder 140, causing the drive cylinder 140 to retract and drive the lever connecting rod 141 to deflect in the opposite direction, causing the pull rod 331 to move upward and the clamp 330 to slide in the opposite direction along the conical ring 312. Under the action of the wedge surface, the clamp 330 radially returns to its original position, releasing the support column 400. The first drive motor 120 reverses, causing the support plate 200 to return to its initial position. The operator can then remove the welded seat assembly and begin the next cycle.
