Description

Technical Field

[0001] This invention relates to the field of furniture welding technology, and in particular to a furniture component welding machine with multi-station intelligent fixing. Background Technology

[0002] In modern furniture manufacturing, metal components are key parts that form the core support and connection functions of metal or composite furniture, directly determining the structural stability, load-bearing capacity, and lifespan of the furniture. Welding of metal furniture (especially chair frames) is a core process in furniture manufacturing. Traditional operations often rely on manual hand-held clamps for positioning and point-by-point welding at a single workstation. Workers need to repeatedly adjust the posture of components and manually tighten the fixing plates and connecting frames, resulting in poor positioning accuracy, low consistency, and quality defects such as misalignment and welding deviation. In the single-workstation mode, loading, clamping, and welding are performed sequentially, leading to long process waiting times and slow production cycles, making it difficult to adapt to high-efficiency mass production. Furthermore, welding involves sparks, high labor intensity, and safety hazards.

[0003] While existing automated welding equipment incorporates robotic arms, its fixture structure is simplistic and its positioning methods are inadequate, failing to provide multi-dimensional synchronous positioning for chair legs, connecting frames, and fixing plates, resulting in insufficient positioning reliability. Most equipment employs a single-station layout, preventing welding and clamping from proceeding in parallel, leading to poor production continuity and low overall efficiency. Therefore, there is an urgent need for a furniture component welding machine with multi-station intelligent fixing capabilities. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a furniture component welding machine with multi-station intelligent fixing.

[0005] The technical solution of this invention is: a furniture component welding machine with multi-station intelligent fixing, including a chassis, a moving component, a multi-axis manipulator, a welding machine, a rotating station, a placement component, a clamping component, and a limiting component. A moving component is located at the center of the top of the chassis, and a multi-axis manipulator is mounted on the moving component. The welding machine is mounted on the multi-axis manipulator. Rotating stations are located on the front left and rear right sides of the top of the chassis. Each rotating station consists of a rotating disk, a connecting shaft, and a drive motor.

Clamping components capable of clamping the chair connecting frame are provided on the left and right sides and the front side of the limiting plate.

[0008] Furthermore, the limiting assembly includes a mounting platform, a mounting block, a rotating shaft, a swing rod, a clamping block, and a second electric push rod. The upper part of the side wall of the placement block away from the limiting plate is provided with a mounting platform, and the upper part of the front and rear side walls of the mounting platform is provided with mounting blocks. A rotating shaft is rotatably provided between the upper parts of two adjacent mounting blocks, and a swing rod is provided on the rotating shaft. A clamping block is provided on the side of the swing rod near the limiting plate. The lower part of the clamping block is made of flexible silicone material. A second electric push rod is provided on the side of the placement plate near the placement block. The second electric push rod is rotatably connected to the swing rod at the end away from the clamping block.

[0009] Furthermore, the clamping assembly includes a clamping frame, a connecting rod, a mounting plate, and a first electric push rod. A slot is spaced apart on the left and right sides of the placement plate, and a slot is spaced apart on the front side of the placement plate. A clamping frame is slidably installed in each slot. A connecting rod is connected between the bottoms of the clamping frames. Mounting plates are provided on the left, right, and front sides of the bottom of the placement plate. A first electric push rod is provided on each mounting plate. The push rod of the first electric push rod is connected to the adjacent connecting rod.

[0010] Furthermore, it also includes fixed sleeves, springs, and cross plates. Fixed sleeves are symmetrically arranged on the front side of the top of the rotating disk of the rotating station. Springs are connected to each fixed sleeve, and cross plates are arranged between the tops of the springs.

[0011] Furthermore, it also includes a placement tray and a cover plate. The placement tray is provided on the top of the placement tray for placing the fixing piece, and the cover plate is placed on the placement tray.

[0012] Furthermore, it also includes a shielding frame and a control panel. The rear left side of the top of the chassis and the front right side of the top of the chassis are equipped with shielding frames to safely shield the area where the chair connecting frame is placed. The control panel is located on the upper part of the shielding frame on the right side. The control panel has a built-in controller, which is connected to the servo motor, drive motor, first electric push rod, second electric push rod, multi-axis robot and welding machine through wiring.

[0013] The beneficial effects of this invention are: 1. This equipment achieves precise positioning of chair legs and connecting frames through limiting sleeves and plates for the placement components. Combined with electrically controlled clamping of the clamping components, it avoids interface misalignment issues caused by manual posture adjustments. Simultaneously, the flexible clamping blocks of the limiting components firmly fix the fixing plates, preventing welding displacement and ensuring a tight fit and a firm, flat joint, effectively avoiding potential quality issues. Compared to existing automated equipment, this equipment's clamping and limiting components can simultaneously achieve multi-dimensional precise positioning of chair legs, connecting frames, and fixing plates, offering greater versatility and adaptability to the welding needs of various furniture metal components, such as chair frames.

[0014] 2. The multi-rotation station design enables parallel welding operations and workpiece preparation, significantly reducing waiting time for loading and clamping. Compared to the single-station mode, operational efficiency is greatly improved, making it suitable for batch production needs. The equipment completes clamping, limiting, and welding processes through fully automated control, reducing manual intervention and lowering the labor intensity of workers. At the same time, the shielding frame effectively blocks welding sparks and slag spatter, avoiding safety risks. Attached Figure Description

[0025] Example: Figures 1-8As shown, a furniture component welding machine with multi-station intelligent fixing includes a housing 1, a moving component 2, a multi-axis manipulator 3, a welding machine 4, a rotating station 5, a placement component 6, a clamping component 7, and a limiting component 8.

Component 6 includes a limiting sleeve 61, a working plate 62, a baffle 63, a placement platform 64, a placement plate 65, a limiting plate 66, and placement blocks 67. Limiting sleeves 61 are symmetrically arranged on the front, back, left, and right sides of the top of the rotating disk. A working plate 62 is located on the rear side of the top of the rotating disk, and a baffle 63 is installed on the working plate 62. A placement platform 64 is located on the top of the rotating disk, and a placement plate 65 is located on the top of the placement platform 64. Limiting plates 66 are installed on the left, right, and front side walls of the placement plate 65. Placement blocks 67 are symmetrically arranged on the left, right, front, and back sides of the top of the placement plate 65, and each placement block 67 has a groove for placing a fixing piece. Clamping components 7 capable of clamping the chair connecting frame are provided on the left, right, and front sides of the limiting plate 66. The placement component 6 is equipped with... A clamping assembly 7 is provided to clamp and fix the front and left / right chair connecting frames. The clamping assembly 7 includes a clamping frame 72, a connecting rod 73, a mounting plate 74, and a first electric push rod 75. A slot 71 is spaced apart on the left and right sides of the placement plate 65, and a slot 71 is spaced apart on the front side of the placement plate 65. A clamping frame 72 is slidably installed in each slot 71. A connecting rod 73 is connected between the bottom of the clamping frames 72. Mounting plates 74 are provided on the bottom left and right sides and the front side of the placement plate 65. A first electric push rod 75 is provided on each mounting plate 74. The push rod of the first electric push rod 75 is connected to the adjacent connecting rod 73. The placement assembly 6 is provided with a limiting assembly 8 that can press the fixing piece that needs to be installed on the left and right chair connecting frames.The limiting assembly 8 includes a mounting platform 81, a mounting block 82, a rotating shaft 83, a swing rod 84, a clamping block 85, and a second electric push rod 86. Mounting platforms 81 are provided on the upper part of the side wall of the placement block 67 away from the limiting plate 66. Mounting blocks 82 are provided on the upper parts of the front and rear side walls of the mounting platform 81. A rotating shaft 83 is rotatably connected between the upper parts of two adjacent mounting blocks 82. A swing rod 84 is provided on the rotating shaft 83. A clamping block 85 is provided on the side of the swing rod 84 near the limiting plate 66. The lower part of the clamping block 85 is made of flexible silicone material. A second electric push rod 86 is provided on the side of the placement plate 65 near the placement block 67. The second electric push rod 86 is rotatably connected to the swing rod 84 at the end away from the clamping block 85. The assembly also includes a shielding bracket. 14 and 15 are control panels. Both the rear left side of the top of chassis 1 and the front right side of the top of chassis 1 are equipped with shielding frames 14 to safely cover the area where the chair connecting frame is placed. The control panel 15 is located on the upper part of the right-side shielding frame 14. The control panel 15 has a built-in controller, which is connected via wiring to the servo motor 27, drive motor, first electric push rod 75, second electric push rod 86, multi-axis robot 3, and welding machine 4. The controller is a PLC controller. The drive motor's start / stop and rotation angle are controlled by the PLC controller, with the rotation angle precisely set to 90° to achieve automatic switching of the workpiece welding surface. The first electric push rod 75's extension and retraction are controlled by the PLC controller, and the clamping stroke and clamping force can be preset and adjusted to prevent component deformation or loosening.

[0026] like Figure 7 As shown, it also includes a fixing sleeve 9, a spring 10 and a horizontal plate 11, a placement plate 12 and a cover plate 13. The rotating station 5 has a fixing sleeve 9 symmetrically arranged on the front side of the top of the rotating plate. The fixing sleeve 9 is connected to a spring 10. The top of the spring 10 is arranged between the tops of the spring 10. The top of the placement plate 65 is provided with a placement plate 12 for placing the fixing piece. The cover plate 13 is placed on the placement plate 12.

[0027] Place the chair back frame on the corresponding position behind the top component 6 of the rotating disk. Precisely insert the bottom of the chair legs on both sides of the back into the symmetrically arranged limiting sleeves 61 on the top of the rotating disk. The limiting sleeves 61 ensure the chair legs are vertically positioned, preventing them from being placed crookedly. Next, place the three chair connecting frames on the corresponding positions of the placement plate 65. Two of the connecting frames are attached to the limiting plates 66 on the left and right sides of the placement plate 65, respectively, and the other connecting frame is attached to the limiting plate 66 on the front side of the placement plate 65. The limiting plates 66 can provide lateral and longitudinal positioning for the connecting frames, ensuring that the connecting frames are accurately positioned and aligned with the connecting parts of the chair legs. Then, insert the bottom of the two front chair legs into the limiting sleeves 61 on the front side of the rotating disk. At this time, the spring 10 on the top fixing sleeve 9 of the rotating disk will use its own elasticity to drive the top horizontal plate 11 to elastically compress the chair legs, making the upper part of the chair legs tightly fit the corresponding connecting frames, completing the initial positioning of the chair components.

[0028] After the workpiece is initially placed, the equipment is started via the control panel 15 on the upper part of the right-side shield 14. After receiving the command, the controller first controls the clamping assembly 7 to move, achieving precise clamping and fixing of the chair connecting frame. The first electric push rod 75 of the clamping assembly 7 extends synchronously. Since the push rod of the first electric push rod 75 is connected to the connecting rod 73 at the bottom of the placement plate 65, and the connecting rod 73 is fixedly connected to the clamping frame 72 in the slot 71, when the first electric push rod 75 extends, it will drive the connecting rod 73 to move synchronously, thereby driving the clamping frame 72 to slide smoothly along the slots 71 on the left, right and front sides of the placement plate 65 until the clamping frame 72 is tightly attached to the outer wall of the three connecting frames. The clamping force of the clamping frame 72 firmly fixes the chair connecting frames on the left, right and front sides to the limiting plate 66 of the placement plate 65, ensuring that the connecting frames will not shift during the welding process and guaranteeing the accuracy of the welding interface. At the same time, the sliding stroke of the clamping frame 72 is precisely controlled by the controller to avoid excessive clamping force causing component deformation or insufficient clamping force causing insecure fixing.

[0029] After the connecting frame is fixed, the fixing plates are placed and tightened. The operator removes the fixing plates from the placement tray 12 at the top of the placement plate 65 and places them one by one into the grooves of the placement blocks 67 symmetrically arranged on the left and right sides and front and back of the top of the placement plate 65. During placement, it is necessary to ensure that the sidewall of the fixing plate is flush with the upper surface of the adjacent connecting frame, ensuring that the welding interface between the fixing plate and the connecting frame is completely fitted, avoiding welding gaps that could affect welding quality. After the fixing plates are in place, the operator sends a command through the control panel 15. The controller controls the extension of the second electric push rod 86 of the limit assembly 8. Since the push rod of the second electric push rod 86 is rotatably connected to the end of the swing rod 84 away from the clamping block 85, and the swing rod 84 is rotatably connected to the mounting block 82 of the mounting platform 81 through the rotating shaft 83, when the second electric push rod 86 extends, it pushes the swing rod 84 to rotate clockwise around the rotating shaft 83, causing the clamping block 85 on the side of the swing rod 84 closest to the limit plate 66 to move downwards synchronously until the clamping block 85 is tightly fitted against the top of the fixing plate. Because the lower part of the clamping block 85 is made of flexible silicone material, it can not only achieve stable clamping of the fixing plate and prevent the fixing plate from shifting during the welding process, but also avoid damage to the fixing plate due to excessive clamping force, thus completing the limiting and fixing of the fixing plate.

[0030] After all workpieces are fixed in place, the welding operation begins. The controller starts the servo motor 27, and the output shaft of the servo motor 27 drives the lead screw 25 between the bearing seats 24 to rotate at a constant speed through the coupling. Since the lead screw 25 is engaged with the nut 26 at the bottom of the mounting base 23, and the mounting base 23 is slidably connected to the straight slide rail 21 on the top of the chassis 1 through the slider 22, the rotation of the lead screw 25 will drive the nut 26 to move along the axis of the lead screw 25, thereby driving the mounting base 23 and its top multi-axis robot 3 and welding machine 4 to move smoothly along the straight slide rail 21 until the welding machine 4 moves directly above one of the rotating stations 5 and aligns with the welding interface of the chair component. Subsequently, according to the preset welding program, the controller controls the multi-axis robot 3 to drive the welding machine 4 to perform precise positioning, continuously and uniformly welding the connection between the chair leg and the connecting frame, and the connection between the fixing piece and the connecting frame. During the welding process, the welding parameters of the welding machine 4 are precisely controlled by the controller to ensure that the welded joint is firm, flat, and meets the welding quality requirements of the furniture components.

[0031] Once the chair component on the side closest to the multi-axis robot 3 on the current rotating station 5 is welded, the controller controls the welding machine 4 to pause its work. At the same time, it controls the drive motor at the bottom of the rotating station 5 to start. The output shaft of the drive motor drives the connecting shaft at the bottom of the rotating disk to rotate at a constant speed through the coupling. This causes the rotating disk and all the workpieces on top of it to rotate 90° around the connecting shaft, moving the unwelded side of the chair component into the working range of the multi-axis robot 3. After that, the drive motor stops working, the rotating disk remains fixed, and the controller controls the multi-axis robot 3 again to drive the welding machine 4 to perform welding operations on the unwelded interfaces until all welding interfaces on the rotating station 5 are welded.

[0032] While the multi-axis robotic arm 3 drives the welding machine 4 to weld a workpiece on one of the rotating stations 5, the operator can move to another idle rotating station 5 and, following the same operating procedure, perform the placement, preliminary positioning, clamping, and placement and clamping of the next set of chair components. Once the welding operation at the current rotating station 5 is completed, the controller controls the servo motor 27 to rotate in the opposite direction, moving the multi-axis robotic arm 3 and the welding machine 4 to another rotating station 5 where workpiece preparation has been completed, immediately starting the welding operation for the next set of workpieces. Simultaneously, the operator can remove the welded workpiece from the rotating station 5, clean off welding residue, and continue preparing for the next set of workpieces. Through the alternating operation of the two rotating stations 5, workpiece preparation and welding operations are synchronized, significantly reducing waiting time and greatly improving overall welding efficiency.

[0033] The shielding brackets 14 installed on the rear left and front right sides of the top of the chassis 1 can safely shield the working area where the chair connecting frame is placed, preventing sparks and slag from splashing during welding and protecting the personal safety of the workers. The control panel 15 can display the working status of each component of the equipment in real time. Workers can adjust welding parameters, pause or stop the operation at any time through the control panel 15 to ensure the safety and controllability of the welding operation.
