[0001] The utility model relates to the technical field of height adjustment equipment, in particular to a support height adjustment device. Background Art

[0002] In modern furniture manufacturing, the efficient operation of the sofa assembly line is crucial for improving production efficiency, reducing costs, and ensuring product quality. Among them, the precise and rapid handling of sofa iron frames or sofa bodies is one of the key links in achieving automated production. Traditionally, this task has been mostly undertaken by three-axis manipulators, which have been widely used in the field of industrial automation due to their flexibility and precision.

[0003] However, with the diversification of sofa styles and the expansion of production scale, the manipulator faces many challenges during the handling process, especially when dealing with sofa iron frames of different sizes and heights. Most of the existing support designs only have basic support functions and cannot automatically adjust according to the actual height of the sofa iron frame, which greatly limits the working efficiency and flexibility of the manipulator.

[0004] Specifically, when encountering sofa iron frames of different heights, the traditional method is to adjust the grasping position of the manipulator to adapt to different heights. This process not only requires precise calculation and manual setting of multiple parameters, such as the lifting height, horizontal displacement, and rotation angle of the manipulator, but also has complex operations and extremely high requirements for the professional skills and experience of operators. Therefore, it is very unfriendly to operators. Summary of the Utility Model

[0005] In order to overcome at least one of the above-mentioned defects of the prior art, the utility model provides a support height adjustment device.

[0015] Further, the support feet include: a support part, which is used for supporting the iron frame; a support foot assembly part, which is fixedly connected to the movable plate.

[0016] By adopting the above solution, the connection strength between the support foot assembly part and the movable plate can be improved, thereby improving the self-strength of the support part, and at the same time having a detachable effect, which is convenient for replacement and maintenance.

[0017] Furthermore, the support foot assembly part is provided with a longitudinal strip-shaped assembly hole, and at least two screws are arranged between the strip-shaped assembly hole and the movable plate.

[0044] It should be noted that in other embodiments, the driving device 3 can also be replaced with a lead screw motor, and the movement of the slider 34 is controlled by the motor to control the lead screw, which can also achieve the purpose of adjusting the movable plate 2.

[0045] Preferably, at least two sliding tracks 111 are provided, and the number of clamping strips 341 of the slider 34 corresponds to the number of the sliding tracks 111. By providing at least two sliding tracks 111, the stability of the slider 34 during sliding can be improved. In Embodiment 1 herein, four sliding tracks 111 are provided, and the number of clamping strips 341 of the slider 34 is also four, and the interaction between them is more stable.

[0046] In a specific embodiment, the support leg 5 includes a support portion 51 and a support leg assembly portion 52. The support portion 51 is used to support the iron frame, and the support leg assembly portion 52 is fixedly connected to the movable plate 2, which can improve the connection strength between the support leg assembly portion 52 and the movable plate 2, thereby improving the self-strength of the support portion 51. At the same time, it has a detachable effect, which is convenient for replacement and maintenance. In Embodiment 1 herein, the support leg assembly portion 52 is provided with a longitudinal strip-shaped assembly hole 521, and at least two screws are provided between the strip-shaped assembly hole 521 and the movable plate 2. The screws can slide along the strip-shaped assembly hole 521 to adjust the relative position between the support leg 5 and the movable plate 2, different types of support legs 5 can be replaced, and the initial height of the support leg 5 can be adjusted to adapt to different sofa iron frames, and the two screws can maintain the assembly stability between the support leg 5 and the movable plate 2.

[0047] In some embodiments of China, in order to improve the support stability between the support portion 51 and the sofa iron frame, optionally, a positioning block 511 is provided on the support portion 51. The positioning block 511 is used to abut against the iron frame, and the positioning block 511 can prevent the iron frame from shaking and improve the support stability.

[0048] In order to facilitate the adjustment of the movable plate 2 relative to the assembly frame 1, in Embodiment 1 herein, a longitudinal flat position hole 21 is provided on the movable plate 2. The fastener 4 includes a locking portion 41 and a connecting portion 42. The connecting portion 42 passes through the flat position hole 21 and is threadedly connected to the assembly frame 1 to adjust the gap between the locking portion 41 and the movable plate 2, which is convenient for achieving a locking effect after height adjustment, improving the support stability, and at the same time achieving the effect of stable support. Specifically, an intermediate connector 14 is provided between the assembly frame and the flat position hole 21. The intermediate connector 14 is formed by bending a sheet metal and encloses a rectangular structure, and the driving device 3 can be avoided in the middle. Preferably, a handle 411 for facilitating operation and rotation is further provided on the locking member, which is convenient for the user to adjust. At the same time, a gasket 43 is also provided between the locking portion 41 and the movable plate 2 to improve the locking strength between the two.

[0049] In order to facilitate improving the accuracy of height adjustment, in some embodiments, a scale 6 is longitudinally provided on the movable plate 2, and a pointer 7 facing the scale 6 is assembled on the assembly frame 1, which can improve the accuracy of height adjustment and reduce errors. In the present Embodiment 1, two parallel assembly edges 22 are provided between the movable plate 2 and the scale 6. An installation platform 23 is assembled on the assembly edge 22, and the scale 6 is fixed to the installation platform 23 by screws. The length of the inserted screws is not higher than the height of the assembly edge 22 protruding from the movable plate 2, thereby providing a receiving space for the screws and not causing damage to the movable plate 2. Due to the existence of the assembly edge 22, the scale 6 can protrude from the movable plate 2, making it more intuitive for users to observe.

[0050] It should be noted that the present seat height adjustment device is not limited to supporting the sofa iron frame, and can also be applied to other production lines for support. No specific limitation is made in this embodiment.

[0051] In the actual production line, the seat height adjustment device is installed at the transfer support station. Specifically, the three-axis manipulator clamps and transports the iron frame to the transfer support station, and then the robotic arm clamps and transfers it to the next station. Since the seat height adjustment device is provided at the support station, it is not necessary to adjust the lowering height of the robotic arm and the three-axis manipulator, reducing the operation complexity. It is only necessary to manually adjust the seat height adjustment device so that the clamped parts of sofa iron frames of different sizes are at the same height. The specific operation of adjusting the height is as follows. Under normal circumstances, the three-axis manipulator can directly transport the iron frame to the support station for support. When the iron frame is of a small size, it is necessary to adjust the seat height adjustment device to maintain the support of the iron frame at the same height. First, the user rotates the handle 411 of the locking member to disengage the movable plate 2 and the assembly frame 1 from the locked state, and then shakes the hand crank 33 to drive the driving screw 32 to rotate. The slider 34 rises along the sliding track 111 and synchronously drives the movable plate 2 to rise until the support feet 5 on the movable plate 2 abut against the iron frame. Then, the handle 411 of the locking member is rotated again to lock the movable plate 2 and the assembly frame 1. At this time, the three-axis manipulator can be disengaged from the clamping state, and the iron frame is supported by the support feet 5 of the seat height adjustment device. Subsequently, the robotic arm clamps and transports the iron frame to the next station.

[0052] In summary, a seat height adjustment device provided by the present utility model has the following technical effects:

[0053] 1. Since the device can quickly and accurately adjust according to the actual parking height of the sofa iron frame, there is no need to frequently adjust the grasping position or parameters of the manipulator, thereby significantly shortening the production preparation time and improving the overall production efficiency;

[0054] 2. Traditional methods require precise calculations and manual setting of multiple parameters, which are complex in operation and demand high professional skills from operators. In contrast, this device simplifies the operation process and reduces the operation difficulty by mechanically adjusting the height of the support. This makes it easier for operators to get started, improves work efficiency, and simultaneously reduces the need for highly skilled operators. This device helps to reduce the overall production cost;

[0055] 3. Since it can accurately adjust the height of the support, ensuring the stability and balance of the sofa iron frame during handling, it reduces damage or defects caused by improper handling, improves product quality and customer satisfaction, and reduces safety hazards such as the sofa iron frame slipping or tilting due to height mismatch, thus ensuring the safety of the production site.

[0056] The technical means disclosed in the solution of this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of this utility model.
