Description

Technical Field

[0001] The utility model relates to the technical field of screwdrivers, in particular to an automatic screw locking machine for sofa iron frames. Background Technique

[0002] In the sofa assembly line, the automatic screw tightening of the iron frame is a key and frequent operation step. Traditional screw tightening stations mostly rely on complex robotic arm systems. Although these systems can achieve high-precision positioning and tightening operations, they face many challenges in practical applications. Specifically, due to the design diversity and size differences of sofa iron frames, especially the different heights, the traditional robotic arm automatic screw tightening equipment is unable to cope well in terms of adaptability and operation convenience.

[0003] Currently, the common robotic arm automatic screw tightening equipment on the market mainly realizes screw tightening through the precise positioning of the robotic arm. However, when facing sofa iron frames with different heights, this equipment needs to pre-adjust the height of the robotic arm to meet the requirements of different iron frames. This adjustment process not only requires manual parameter modification but is often cumbersome and time-consuming, greatly affecting production efficiency and operation flexibility. Content of the Utility Model

[0004] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides an automatic screw locking machine for sofa iron frames, which can achieve its own height fine-tuning effect, avoid changing the operation parameters of the robotic arm, and greatly reduce the operation complexity.

[0005] The technical solution adopted by the utility model to solve its problems is as follows:

[0006] An automatic screw locking machine for sofa iron frames, comprising: an assembly plate, on one side of which an adjustment track is provided; a sliding mounting seat slidably mounted on the adjustment track; a driving member driving the sliding mounting seat to perform a linear reciprocating motion along the adjustment track; a screw locking device assembled on the sliding mounting seat, the screw locking device including a screw locking motor and a screw locking sleeve, the screw locking motor being fixed on the sliding mounting seat, and the output shaft of the screw locking motor being drivingly connected to the screw locking sleeve, and the axis direction of the screw locking motor being parallel to the adjustment track.

[0007] By adopting the above solution, through the design of introducing the sliding mounting seat and the adjustment track, the screw locking device can perform a linear reciprocating motion along the adjustment track, thereby realizing height fine-tuning. This design avoids the need for frequent manual modification of the robotic arm height parameters, improves the adaptability and operation convenience of the equipment; through the automatic height fine-tuning function, the operation process is greatly simplified, the operation complexity is reduced, and the production efficiency is improved.

[0008] Furthermore, the sliding mounting seat comprises a motor assembly portion and a sliding portion, and along the direction of the adjustment track, the length of the motor assembly portion is smaller than the length of the sliding portion.

[0009] By adopting the above solution, the motor assembly part is mainly used to fix the key components such as the screw locking motor, while the sliding part is responsible for sliding on the adjustment track. Since the length of the motor assembly part is shorter than the length of the sliding part, this design makes the center of gravity of the sliding mount more inclined to the sliding part, which is conducive to maintaining the overall stability during the sliding process and reducing the deviation caused by vibration or impact.

[0010] Furthermore, the screw locking motor is located on one side of the motor assembly part, and an adjusting cylinder is installed on the other side of the motor assembly part. The piston rod of the adjusting cylinder passes through the motor assembly part and is connected to the screw locking motor.

[0011] By adopting the above solution, the introduction of the adjusting cylinder enables the locking screw motor to be precisely fine-tuned in the vertical direction. By controlling the extension and retraction of the piston rod of the adjusting cylinder, the position of the locking screw motor can be fine-tuned, thereby adjusting the relative position between the locking screw sleeve and the screw to be tightened, ensuring the accuracy and reliability of the tightening operation.

[0012] Furthermore, a guide structure is provided between the locking screw motor and the sliding portion, and when the adjusting cylinder adjusts the position of the locking screw motor, the guide structure is used to provide a guiding force for the locking screw motor.

[0013] By adopting the above solution, the linearity and accuracy of the screw locking motor during movement are ensured, and the reduction of tightening accuracy due to deviation or shaking is avoided.

[0014] Furthermore, the guide structure includes: a guide sleeve, a guide groove is provided on one side of the guide sleeve, and the guide sleeve moves according to the displacement of the lock screw motor; a guide rib, the guide rib is provided on the side of the motor assembly part away from the adjustment track, and the guide rib is slidably arranged in the guide groove.

[0015] By adopting the above scheme, the combination of the guide sleeve and the guide rib provides precise guiding force for the locking screw motor, ensuring its stability and linearity during the adjustment process. The guide structure is simple and practical in design, and has high reliability and durability. It can maintain good working performance even under high-frequency and high-intensity use conditions.

[0016] Furthermore, a detachable plate is provided between the guide rib and the motor assembly portion, the guide rib is integrally provided on the detachable plate, and the detachable plate is detachably connected to the motor assembly portion.

[0017] By adopting the above solution, the guiding ribs are integrally arranged on the detachable plate. This integrated design enhances the stability and rigidity of the guiding ribs. Due to the detachable nature of the detachable plate, when the guiding ribs are deformed or damaged, only the detachable plate needs to be replaced, greatly reducing the maintenance cost. At the same time, it can adapt to sofa iron frames of different models and sizes, enhancing the adaptability and flexibility of the equipment.

[0018] Further, set the length of the guiding rib as X and the length of the adjusting track as Y, then the total displaceable length of the lock nut sleeve is X + Y.

[0019] By adopting the above solution, by setting the guiding rib and the adjusting track, the adjustable length of the lock nut sleeve can be extended. Therefore, even if the size of the assembly plate is reduced, long-distance adjustment can still be achieved.

[0020] Further, a robotic arm connecting seat is arranged on the other side of the assembly plate.

[0021] By adopting the above solution, it is convenient to connect the assembly plate with the robotic arm.

[0022] Further, the number of the adjusting tracks is at least two.

[0023] By adopting the above solution, multiple adjusting tracks can disperse the weights of components such as the sliding mounting seat and the lock nut motor thereon, reducing the risk of single-point stress and improving the overall stability and durability.

[0024] Further, the driving member is a telescopic air cylinder or a lead screw motor.

[0025] By adopting the above solution, stable adjustment of the lock nut device can be achieved.

[0026] In summary, an automatic screw locking machine for a sofa iron frame provided by the present utility model has the following technical effects:

[0027] 1. Improve adaptability and flexibility: Due to the introduction of the design of the sliding mounting seat and the adjusting track, the lock nut device can perform linear reciprocating motion along the adjusting track, thereby realizing fine height adjustment. This design enables the equipment to easily adapt to sofa iron frames of different heights and sizes, greatly improving the adaptability and flexibility of the equipment.

[0028] 2. Simplify the operation process: For traditional robotic arm automatic screw tightening equipment, when facing sofa iron frames of different heights, it is necessary to frequently manually modify the height parameters of the robotic arm, which is a cumbersome and time-consuming process. However, this equipment greatly simplifies the operation process, reduces manual intervention, and improves production efficiency through the automatic fine height adjustment function.

[0029] 3. Reduce operation complexity: The need for manual parameter modification is avoided, reducing the possibility of human error and also alleviating the burden on operators. Operators only need to simply set the initial parameters, and the device can automatically complete subsequent fine-tuning work, greatly reducing operation complexity.

[0030] 4. Improve production efficiency: Due to the simplification of the operation process and the reduction of operation complexity, the device can adapt to different production requirements faster, reducing the time wasted due to equipment adjustment. At the same time, stable automated operation also ensures the accuracy and consistency of tightening, thus improving the overall production efficiency.

[0031] 5. Enhance equipment stability: The design of the sliding mounting base and the adjustment track makes the screw locking device more stable and reliable during movement. This stable structure not only reduces errors caused by vibration or impact but also extends the service life of the equipment. Brief Description of the Drawings

[0037] For the convenience of understanding the embodiments of the present utility model, the following will further explain with specific examples with reference to the drawings, and each embodiment does not constitute a limitation on the embodiments of the present utility model.

[0038] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0040] Refer to Embodiment 1 of the present utility model Figures 1-3 As shown, a sofa iron frame automatic screw locking machine is disclosed, which includes an assembly plate 1, a sliding mounting seat 2, a driving member 3 and a screw locking device 4. One side of the assembly plate 1 is provided with an adjustment track 11, and the sliding mounting seat 2 is slidably arranged on the adjustment track 11. Optionally, the adjustment track 11 can be a convex track or a concave track, and correspondingly, the sliding mounting seat 2 is provided with a chute or a convex rib adapted to the convex track or the concave track to achieve a sliding effect. The driving member 3 drives the sliding mounting seat 2 to perform a linear reciprocating motion along the adjustment track 11. Preferably, the driving member 3 is preferably a telescopic cylinder or a screw motor, which can realize stable adjustment of the screw locking device 4. The screw locking device 4 is assembled on the sliding mounting seat 2. The screw locking device 4 includes a screw locking motor 41 and a screw locking sleeve 42. The screw locking motor 41 is fixed on the sliding mounting seat 2, and the output shaft of the screw locking motor 41 is drivingly connected to the screw locking sleeve 42. The axis direction of the screw locking motor 41 is parallel to the adjustment track 11. By introducing the design of the sliding mounting seat 2 and the adjustment track 11, the screw locking device 4 can perform a linear reciprocating motion along the adjustment track 11, thereby realizing fine height adjustment. This design avoids the need to frequently manually modify the height parameters of the robotic arm, improves the adaptability and operation convenience of the equipment; through the automatic height fine adjustment function, the operation process is greatly simplified, the operation complexity is reduced, and the production efficiency is improved.

[0041] It should be noted that the number of the adjustment tracks 11 is at least two. Multiple adjustment tracks 11 can disperse the weights of the sliding mounting seat 2 and components such as the screw locking motor 41 thereon, reduce the risk of single-point stress, and improve the overall stability and durability.

[0042] In a specific embodiment, the sliding mounting base 2 includes a motor assembly portion 21 and a sliding portion 22. Along the direction of the adjustment track 11, the length of the motor assembly portion 21 is less than the length of the sliding portion 22, so that the center of gravity of the sliding mounting base 2 is more biased towards the sliding portion 22, which is beneficial to maintaining the overall stability during the sliding process and reducing the deviation caused by vibration or impact. That is, there is a height difference between the motor assembly portion 21 and the sliding portion 22. Optionally, the motor assembly portion 21 and the sliding portion 22 can be aligned on one side and arranged in a stepped manner on the other side. Of course, they can also be arranged in a stepped manner on both sides, which is not specifically limited in this embodiment.

[0043] In order to increase the adjustable length of the screw-locking sleeve 42 without increasing the size of the assembly plate 1, in some embodiments, an adjustment cylinder 5 is further provided on the motor assembly portion 21. Specifically, the adjustment cylinder 5 is attached to one side of the motor assembly portion 21 by screws, and the piston rod of the adjustment cylinder 5 passes through the motor assembly portion 21 and is connected to the screw-locking motor 41, so that the screw-locking motor 41 is located on one side of the motor assembly portion 21, and the adjustment cylinder 5 is located on the other side of the motor assembly portion 21. The introduction of the adjustment cylinder 5 enables the screw-locking motor 41 to perform precise fine adjustment in the vertical direction. By controlling the telescopic movement of the piston rod of the adjustment cylinder 5, the position of the screw-locking motor 41 can be finely adjusted, and then the relative position between the screw-locking sleeve 42 and the screw to be tightened can be adjusted to ensure the accuracy and reliability of the tightening operation.

[0044] In some embodiments, since the piston rod may shake during the adjustment process, in order to improve the tightening accuracy and ensure the linearity and accuracy of the locking screw motor 41 during movement, a guiding structure 6 is provided between the locking screw motor 41 and the sliding part 22. When the adjusting cylinder 5 adjusts the position of the locking screw motor 41, the guiding structure 6 is used to provide a guiding force for the locking screw motor 41, avoiding the decrease in tightening accuracy caused by deviation or shaking. In this Embodiment 1, the guiding structure 6 includes a guiding sleeve 61 and a guiding rib 62. A guiding groove 611 is provided on one side of the guiding sleeve 61, and the guiding sleeve 61 moves along with the displacement of the locking screw motor 41. The guiding rib 62 is provided on the side of the motor assembly part 21 away from the adjusting track 11, and the guiding rib 62 slides in the guiding groove 611. Of course, in other embodiments, the guiding rib 62 and the guiding groove 611 can be interchanged. The combination of the guiding sleeve 61 and the guiding rib 62 provides an accurate guiding force for the locking screw motor 41, ensuring its stability and linearity during the adjustment process. The guiding structure 6 is simple and practical in design, and has high reliability and durability. Even under high-frequency and high-intensity usage conditions, it can maintain good working performance. Set the length of the guiding rib 62 as X and the length of the adjusting track 11 as Y, then the total displaceable length of the locking screw sleeve 42 is X + Y. By providing the guiding rib 62 and the adjusting track 11, the adjustable length of the locking screw sleeve 42 can be extended. Therefore, even if the size of the assembly plate 1 is reduced, a long-distance adjustment can still be achieved.

[0045] When the guiding groove 611 and the guiding rib 62 are worn, it is necessary to replace the sliding mounting seat 2 and the guiding sleeve 61, resulting in the loss of consumables. To solve the above problems, in some embodiments, a detachable plate 63 is provided between the guiding rib 62 and the motor assembly part 21. The guiding rib 62 is integrally provided on the detachable plate 63, and the detachable plate 63 is detachably connected to the motor assembly part 21. Since the guiding rib 62 is integrally provided on the detachable plate 63, the stability and rigidity of the guiding rib 62 are enhanced. According to the detachable property of the detachable plate 63, when the guiding rib 62 is deformed or damaged, only the detachable plate 63 needs to be replaced, greatly reducing the maintenance cost; at the same time, it can adapt to different models and sizes of sofa iron frames, enhancing the adaptability and flexibility of the equipment.

[0046] Optionally, a robotic arm connecting seat 7 is provided on the other side of the assembly plate 1, facilitating the connection between the assembly plate 1 and the robotic arm. A laser positioning device can also be provided on the driving part 3 to improve the alignment operation with the bolt.

[0047] In summary, the automatic screw locking machine for sofa iron frames provided by the present utility model has the following technical effects:

[0048] 1. Improved adaptability and flexibility: Due to the introduction of the design of the sliding mounting seat 2 and the adjustment track 11, the locking screw device 4 can perform linear reciprocating motion along the adjustment track 11, thereby achieving height fine-tuning.

[0049] 2. Simplify the operation process: When facing sofa iron frames of different heights, the traditional mechanical arm automatic screw tightening equipment needs to frequently manually modify the height parameters of the mechanical arm. This process is cumbersome and time-consuming. However, this equipment greatly simplifies the operation process, reduces manual intervention, and improves production efficiency through the automatic height fine-tuning function.

Improve production efficiency: Due to the simplification of the operation process and the reduction of operation complexity, the equipment can adapt to different production needs more quickly, reducing the time wasted in adjusting the equipment. At the same time, stable automatic operation also ensures the accuracy and consistency of tightening, thereby improving the overall production efficiency.

[0052] 5. Enhanced equipment stability: The design of the sliding mounting base 2 and the adjusting rail 11 makes the locking screw device 4 more stable and reliable during movement.
