Description

Technical Field

[0001] This invention relates to the field of sofa processing machinery and equipment technology, specifically to an automated assembly and positioning processing device for sofa frames. Background Technology

[0002] Currently, most sofa frames are made of wood. In automated assembly production, the frames are usually transported directly by conveyor belts for processing. This often results in the following problems: the frames are prone to lateral shift during transport, and there is a lack of effective automatic centering correction mechanisms. This leads to poor positioning accuracy in subsequent assembly, drilling, and splicing, and problems such as assembly misalignment and insufficient frame squareness are likely to occur.

[0003] The existing technical solutions have obvious limitations in practice: the sofa frame is prone to lateral deviation on the conveyor belt. If it cannot be corrected, subsequent assembly, drilling, splicing and other processes will have positioning deviations, hole misalignments and inaccurate assembly, resulting in poor frame squareness, irregular structure and a significant reduction in the finished product qualification rate. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated assembly and positioning processing device for sofa frames. This device solves the problem mentioned in the background that sofa frames are prone to lateral deviation on the conveyor belt. If this deviation cannot be corrected, subsequent assembly, drilling, and splicing processes will experience positioning deviations, hole misalignments, and inaccurate assembly, resulting in poor frame squareness, irregular structure, and a significant reduction in the finished product qualification rate.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated assembly and positioning processing device for sofa frames, comprising a support frame and a conveyor belt mounted on the support frame, the automated assembly and positioning processing device for sofa frames further comprising: A positioning mechanism, installed on the bracket, is used to position and center the sofa frame; The positioning mechanism includes a sliding plate, a second motor mounted on the sliding plate, a reciprocating lead screw mounted on the second motor, a grooved rod mounted on the sliding plate, a sliding seat slidably mounted on the grooved rod, a connecting rod threaded onto the reciprocating lead screw, a sliding rod sliding within the sliding seat, a spherical seat mounted on the sliding rod, and a clamping plate mounted on the spherical seat. The multiple sliding seats are interconnected by the connecting rod; A spring is provided between the slide rod and the slide seat; the slide rod is driven to return to its original position by the spring. The surface of the clamping plate is provided with a waterproof and wear-resistant layer.

[0006] In the above embodiment, the sliding plates on both sides move toward the sofa frame. During the movement of the sliding plates, the motor, the reciprocating lead screw, and the slide rail move synchronously. The movement of these three components then drives the connecting rod, the sliding seat, and the slide rod to move synchronously. The movement of the slide rod then drives the clamping plate to move, so that the clamping plate finally contacts the surface of the sofa frame.

[0007] According to the above technical solution, the positioning mechanism further includes a connecting frame mounted on the bracket, a motor mounted on the connecting frame, a gear mounted on the motor, and a slide rail mounted on the connecting frame.

[0008] In the above embodiment, the motor drives the gear to rotate, and the rotation of the gear drives the racks on both sides to move. The movement of the racks drives the sliding plate to move along the slide rail frame.

[0009] According to the above technical solution, the positioning mechanism further includes a drive rack mounted on a sliding plate, the sliding plate being slidably mounted in a slide rail frame; the drive rack meshes with a gear.

[0010] According to the above technical solution, the automated assembly and positioning processing device for sofa frames further includes a steering mechanism and a blocking mechanism; the steering mechanism is installed on the bracket and is used to turn and transport the sofa frame; the blocking mechanism is installed on the bracket and is used to physically block subsequent sofa frames during turning.

[0011] According to the above technical solution, the steering mechanism includes a mounting bracket mounted on a support, a hydraulic rod mounted on the mounting bracket, a mounting plate mounted on the hydraulic rod, and a guide rod mounted on the mounting plate.

[0012] In the above embodiment, the mounting plate is driven to move upward by a hydraulic rod, and the movement of the mounting plate causes the guide rod to move along the mounting frame.

[0013] According to the above technical solution, the steering mechanism further includes an L-shaped frame mounted on the mounting plate, a second hydraulic rod mounted on the L-shaped frame, and a connecting button mounted on the second hydraulic rod.

[0014] According to the above technical solution, the steering mechanism further includes a rotating seat mounted on the mounting plate, a steering rod rotatably mounted on the rotating seat, and a connecting button for connecting the steering rod and the hydraulic rod two.

[0015] In the above embodiment, when the mounting plate moves, it synchronously drives the L-shaped frame and the rotating seat to move. The movement of the L-shaped frame drives the hydraulic rod two to move, and the movement of the rotating seat drives the steering rod to move upward, lifting the sofa frame and removing it from the conveyor belt. At this time, the hydraulic rod two drives the connecting button to make the steering rod rotate 90 degrees, driving the sofa frame to turn 90 degrees.

[0016] According to the above technical solution, the steering mechanism also includes a limiting plate mounted on the rotating seat and a limiting button mounted on the steering rod.

[0017] In the above embodiment, when the steering rod rotates, it drives the limiting button to rotate. The rotation of the limiting button is forcibly restricted by the limiting plate, so that the rotation angle is exactly ninety degrees.

[0018] According to the above technical solution, the blocking mechanism includes an inlet belt mounted on a bracket and a receiving frame mounted on a guide rod.

[0019] According to the above technical solution, the barrier mechanism further includes a barrier plate mounted on the receiving frame, a slide rail rod mounted on the barrier plate, an extension plate slidably mounted on the slide rail rod, and an adjusting rod for adjusting the position of the extension plate; the adjusting rod has a reciprocating spiral groove; the extension plate has a groove matching the reciprocating spiral groove; the extension plate is threaded onto the adjusting rod; and the surface of the extension plate has an elastic edging.

[0020] In the above embodiment, before the sofa frame enters the conveyor belt on the inlet belt, the hydraulic rod can lift the receiving frame to move. The movement of the receiving frame will drive the barrier plate to move, and the movement of the barrier plate will drive the extension plate to move, thereby physically blocking the sofa frame behind.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the sofa frame is transported via a conveyor belt. Due to inertia and uneven friction, the sofa frame is prone to lateral shifting on the conveyor belt. To address this, the conveyor belt is temporarily stopped when the sofa frame reaches the center position. A positioning mechanism forces the shifted or skewed frame back to the center line of the conveyor belt, ensuring that subsequent drilling, splicing, and locking processes are aligned with the reference points and maintain consistent positioning. This prevents misalignment during assembly, hole deviations, and frame failure due to misalignment. The plywood surface is coated with a waterproof and wear-resistant material, which prevents moisture from contacting the wood and causing the frame to expand or contract due to dampness. It can also prevent the plywood itself from rusting, ensure the clamping surface is flat, and achieve stable and non-destructive centering correction. When the plywood contacts the sofa frame, the sliding friction is changed to rolling friction through the spring and ball seat. The plywood can swing slightly when it contacts the sofa frame, conforming to the slight curvature and unevenness of the wood surface, ensuring uniform clamping force and preventing local suspension or hard top. For taller frames, the position of the plywood can be adjusted in time so that the clamping force of the plywood always acts on the vicinity of the center of gravity of the sofa frame or the middle of the side, avoiding tipping over due to the clamping point being too high or tilting due to the clamping point being too low, and ensuring that the centering correction process is stable and reliable.

[0022] 2. In this invention, sofa frames on automated assembly lines often require drilling, nailing, and splicing of the sides, ends, and top surfaces in sequence. When the sofa frame is transported to the turning mechanism via the conveyor belt, i.e., at the center of the turning rod, it is lifted by the turning rod and rotated 90 degrees, causing the sofa frame to turn 90 degrees. This enables automatic reversal of the sofa frame without the need for manual flipping or additional multi-station equipment, significantly improving the continuity and automation of the entire production line. When the turning rod rotates, it drives the limiting button to rotate. The rotation of the limiting button is forcibly restricted by the limiting plate, ensuring that the rotation angle is exactly 90 degrees. This avoids the angle being too large or too small due to motor inertia, load fluctuations, and transmission clearance, ensuring that the frame is in the same position after each turn, providing a stable benchmark for subsequent assembly, drilling, and positioning processing.

[0023] 3. In this invention, before the sofa frame enters the conveyor belt, the hydraulic rod lifts the receiving frame, which in turn moves the barrier plate. The barrier plate then moves the extension plate, physically blocking the sofa frame behind it and preventing it from accidentally moving forward. This allows for reliable separation between the processed frame and the frame to be processed, preventing multiple frames from being continuously squeezed, stacked, or collided. It ensures that only one frame enters the processing station at a time, achieving orderly processing at a single station and avoiding congestion and material jams on the production line. Simultaneously, the position of the extension plate can be adjusted by rotating the adjusting rod, allowing it to move along the slide rail. The blocking position can be flexibly adjusted according to the length of the sofa frame, achieving precise interval control for frames of different sizes. The device is more versatile and meets the needs of production lines for multiple sofa frame models. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: Please see Figures 1-8 One embodiment of the present invention is: an automated assembly and positioning processing device for sofa frames, comprising a support 1 and a conveyor belt 2 mounted on the support 1, the automated assembly and positioning processing device for sofa frames further comprising: The positioning mechanism, installed on bracket 1, is used to position and center the sofa frame. The positioning mechanism includes a sliding plate 14, a second motor 16 mounted on the sliding plate 14, a reciprocating lead screw 17 mounted on the second motor 16, a sliding groove rod 18 mounted on the sliding plate 14, a sliding seat 110 slidably mounted on the sliding groove rod 18, a connecting rod 19 threadedly mounted on the reciprocating lead screw 17, a sliding rod 111 sliding in the sliding seat 110, a ball seat 112 mounted on the sliding rod 111, and a clamping plate 113 mounted on the ball seat 112. Multiple sliding seats 110 are interconnected by connecting rods 19; A spring is provided between the slide rod 111 and the slide seat 110; The surface of the plywood 113 is provided with a waterproof and wear-resistant layer.

[0028] In the above embodiments, the clamping plate 113 can swing slightly when it contacts the sofa frame, conforming to the slight curvature and unevenness of the wood surface, ensuring uniform clamping force and preventing local suspension or hard tops. For taller frames, the position of the clamping plate 113 can be adjusted in time so that the clamping force of the clamping plate 113 always acts on the vicinity of the center of gravity of the sofa frame or the middle of the side, avoiding tipping over due to excessively high clamping points or tilting due to excessively low clamping points, and ensuring a stable and reliable centering and correction process.

[0029] The positioning mechanism also includes a connecting frame 10 mounted on the bracket 1, a motor 11 mounted on the connecting frame 10, a gear 12 mounted on the motor 11, and a slide rail 13 mounted on the connecting frame 10.

[0030] The positioning mechanism also includes a drive rack 15 mounted on a sliding plate 14, which is slidably mounted in a slide frame 13; the drive rack 15 meshes with a gear 12.

[0031] In the above embodiments, the sofa frame can be flexibly pushed and its position corrected, so that the originally offset and skewed frame is forced to move to the center line position of the conveyor belt 2, ensuring that subsequent processing steps such as drilling, splicing, and locking are aligned with the reference and the position is uniform, avoiding assembly misalignment, hole deviation, and frame scrap due to misalignment.

[0032] The automated assembly and positioning processing device for sofa frames also includes a steering mechanism and a blocking mechanism; the steering mechanism is mounted on the support 1 and is used to guide and transport the sofa frame; the blocking mechanism is mounted on the support 1 and is used to physically block subsequent sofa frames during steering.

[0033] In this embodiment, the sofa frame is transported via conveyor belt 2. Due to inertia and uneven friction, the sofa frame is prone to lateral displacement on conveyor belt 2. When the sofa frame reaches the center position of conveyor belt 2, conveyor belt 2 is temporarily stopped. Then, motor 11 drives gear 12 to rotate. The rotation of gear 12 moves the two drive racks 15 on both sides. The movement of the drive racks 15 moves the sliding plates 14 along the slide rail frame 13, causing the sliding plates 14 on both sides to move towards the sofa frame. During the movement of the sliding plates 14, motor 2 16, reciprocating lead screw 17, and sliding... The three components of the groove rod 18 move synchronously, which in turn drives the connecting rod 19, sliding seat 110, and slide rod 111 to move synchronously. The movement of slide rod 111 then drives the clamping plate 113 to move, so that the clamping plate 113 finally contacts the surface of the sofa frame, performing flexible pushing and position correction on the sofa frame. This forces the originally offset or skewed frame to the center line position of the conveyor belt 2, ensuring that subsequent drilling, splicing, and locking processes are aligned with the reference and have consistent positions. This avoids assembly misalignment, hole deviation, and frame scrap due to misalignment. The surface of the clamping plate 113 is coated with a waterproof and wear-resistant coating. It can prevent moisture from contacting the wood and causing the frame to expand and contract due to dampness, and it can also prevent the plywood 113 from rusting itself, ensuring a flat clamping surface and achieving stable and damage-free centering correction. When the plywood 113 contacts the sofa frame, the spring provides elastic thrust, which can adapt to wooden frames of different widths and slight warping deformations, avoiding rigid clamping that could damage the wood or crack the edges. The impact is buffered at the moment of contact with the sofa frame, reducing wood bumps, chipping, and edge breakage, improving the surface integrity rate of the wood and the appearance quality of the finished product. The spherical seat 112 changes sliding friction to rolling friction, which can reduce the amount of friction when the plywood 113 contacts the sofa frame. The clamping mechanism oscillates to conform to the slight curvature and unevenness of the wood surface, ensuring even clamping force and preventing localized suspension or hardening. For taller frames, the position of the clamping plate 113 can be adjusted promptly. Specifically, the reciprocating screw 17 is rotated by the motor 16, which in turn moves the connecting rod 19. The movement of the connecting rod 19 ultimately moves the clamping plate 113, adjusting its height. This ensures that the clamping force of the clamping plate 113 always acts near the center of gravity of the sofa frame or the middle of the side, preventing tipping due to excessively high clamping points or tilting due to excessively low clamping points, and ensuring a smooth and reliable centering and correction process.

[0034] Example 2: Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the steering mechanism includes a mounting bracket 20 mounted on the bracket 1, a hydraulic rod 21 mounted on the mounting bracket 20, a mounting plate 22 mounted on the hydraulic rod 21, and a guide rod 23 mounted on the mounting plate 22.

[0035] The steering mechanism also includes an L-shaped bracket 24 mounted on the mounting plate 22, a hydraulic rod 25 mounted on the L-shaped bracket 24, and a connecting button 28 mounted on the hydraulic rod 25.

[0036] The steering mechanism also includes a rotating seat 26 mounted on the mounting plate 22, a steering rod 27 rotatably mounted on the rotating seat 26, and a connecting button 28 for connecting the steering rod 27 and the hydraulic rod 25.

[0037] In the above embodiments, the sofa frame can be automatically reversed without manual flipping or additional multi-station equipment, which significantly improves the continuity and automation of the entire production line.

[0038] The steering mechanism also includes a limiting plate 29 mounted on the rotating seat 26 and a limiting button 210 mounted on the steering rod 27.

[0039] In the above embodiments, the rotation angle is precisely 90 degrees to avoid the rotation angle being too large or too small due to motor inertia, load fluctuations, and transmission clearance. This ensures that the frame is in the same position after each rotation, providing a stable reference for subsequent assembly, drilling, and positioning processing.

[0040] In this embodiment, during operation: On an automated assembly line, the sofa frame often requires drilling, nailing, and splicing of the sides, ends, and top surface in sequence. When the conveyor belt 2 transports the sofa frame to the range of the steering mechanism, specifically to the center of the steering rod 27, the hydraulic rod 21 drives the mounting plate 22 to move upwards. The movement of the mounting plate 22 causes the guide rod 23 to move along the mounting frame 20. Simultaneously, the movement of the mounting plate 22 moves the L-shaped frame 24 and the rotating seat 26. The movement of the L-shaped frame 24 causes the hydraulic rod 25 to move, and the movement of the rotating seat 26 causes the steering rod 27 to move upwards, lifting the sofa frame and detaching it from the conveyor belt. 2. At this point, the hydraulic rod 25 drives the connecting button 28 to make the steering rod 27 rotate 90 degrees, causing the sofa frame to turn 90 degrees. This enables the sofa frame to automatically change direction without manual flipping or additional multi-station equipment, significantly improving the continuity and automation of the entire production line. When the steering rod 27 rotates, it drives the limiting button 210 to rotate. The rotation of the limiting button 210 is forcibly restricted by the limiting plate 29, ensuring that the rotation angle is exactly 90 degrees. This avoids the rotation angle being too large or too small due to motor inertia, load fluctuations, and transmission clearance, ensuring that the frame position is consistent after each turn, providing a stable benchmark for subsequent assembly, drilling, and positioning processing.

[0041] Example 3: Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the blocking mechanism includes an inlet belt 30 mounted on the bracket 1 and a receiving frame 31 mounted on the guide rod 23.

[0042] In the above embodiment, the sofa frame enters the conveyor belt 2 on the inlet belt 30.

[0043] The barrier mechanism also includes a barrier plate 32 mounted on the receiving frame 31, a slide rail rod 33 mounted on the barrier plate 32, an extension plate 34 slidably mounted on the slide rail rod 33, and an adjusting rod 35 for adjusting the position of the extension plate 34; the adjusting rod 35 is provided with a reciprocating spiral groove; the extension plate 34 is provided with a groove matching the reciprocating spiral groove; the extension plate 34 is threaded onto the adjusting rod 35; and the surface of the extension plate 34 is provided with an elastic edge.

[0044] In the above embodiments, the processed frame and the frame to be processed can be reliably separated, preventing multiple frames from being continuously squeezed, stacked, or collided. This ensures that only one frame enters the processing station at a time, achieving orderly processing at a single station and avoiding congestion and material jams on the production line. At the same time, the position of the extension plate 34 can be adjusted by rotating the adjusting rod 35, allowing the extension plate 34 to move along the slide rail rod 33. The blocking position can be flexibly adjusted according to the length of the sofa frame, achieving precise interval control for frames of different sizes. The device has greater versatility and meets the needs of production lines for multiple sofa frame models.

[0045] In this embodiment, before the sofa frame enters the conveyor belt 2 on the inlet belt 30, the hydraulic rod 21 lifts the receiving frame 31, which in turn moves the barrier plate 32. The barrier plate 32 then moves the extension plate 34, physically blocking the sofa frame behind it and preventing it from accidentally moving forward. This allows for reliable separation between the processed frame and the frame to be processed, preventing multiple frames from being continuously squeezed, stacked, or collided. It ensures that only one frame enters the processing station at a time, achieving orderly processing at a single station and avoiding congestion and material jams on the production line. At the same time, the position of the extension plate 34 can be adjusted by rotating the adjusting rod 35, allowing the extension plate 34 to move along the slide rail 33. The blocking position can be flexibly adjusted according to the length of the sofa frame, achieving precise interval control for frames of different sizes. The device is more versatile and meets the needs of production lines for multiple sofa frame models.
