Description

Technical Field

[0001] The invention relates to intelligent sofa production equipment, in particular to an intelligent sofa production line. Background Art

[0002] With the improvement of material level, people's requirements for enjoyment are getting higher and higher. For this reason, smart sofas with multiple functions have begun to appear on the market. Smart sofas can adjust the backrest, seat height, tilt angle, etc. according to the user's preferences to meet the personalized needs of different customers. Some smart sofas also have intelligent recognition functions, which can automatically identify the user's height, weight and other information, and automatically adjust the height, angle and hardness of the sofa accordingly to provide users with the best comfort. Smart sofas are usually equipped with heating functions, which can provide a warm and comfortable sitting and lying experience in cold weather. The massage function can relieve user fatigue and improve the quality of life. Some smart sofas can also automatically adjust the massage intensity and mode according to the user's fatigue level.

[0003] As the functions increase, the structure of smart sofas becomes more and more complex, while existing smart sofa manufacturers still use the production and installation methods of conventional sofas. Conventional sofa assembly generally adopts a bottom-up assembly method, that is, the sofa base is used as a reference, and components are continuously installed on the base until the sofa is fully assembled. At the same time, the installation station is fixed and needs to be installed from beginning to end. Due to the space limitation of the installation station, a maximum of two technicians are arranged at one station to be responsible for assembly. Even if the number of people is increased, it is difficult to significantly improve the installation efficiency. Therefore, the traditional production and assembly method is difficult to meet the efficient production requirements of smart sofas. Summary of the invention

[0004] The invention provides a smart sofa production line, which solves the problem in the prior art that the traditional production and assembly method is difficult to meet the efficient production requirements of the smart sofa.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: A smart sofa production line includes a plurality of flow plates, a plurality of linear flow tables and two reversing flow tables;

[0006] The circulation plate is also provided with a rotating platform, and the rotating platform is provided with a clamp for clamping and fixing the base of the smart sofa;

[0007] The linear flow table is composed of a bracket, a horizontal conveying assembly and two guide plates. The flow plate can be placed flat on the horizontal conveying assembly and between the two guide plates. The horizontal conveying assembly can push the flow plate to move along the length direction of the guide plates.

[0008] The reversing flow table is additionally provided with a transverse guide rail, a roller rolling on the guide rail, and a reversing power assembly driving the roller to roll on the basis of the linear flow table. The roller is provided at the bottom of the bracket. The distribution direction of the transverse guide rail is perpendicular to the conveying direction of the horizontal conveying assembly. The reversing power assembly is provided on the bracket. The horizontal conveying assembly on the reversing flow table can convey the flow plate to each other with the horizontal conveying assembly on the linear flow table.

[0009] The straight flow turntables are divided into two groups and placed end to end in a longitudinal direction to form a first flow line and a second flow line that are distributed in reverse parallel. The two reversing flow turntables are respectively arranged at the two ends of the two flow lines.

[0010] The flow plate in the present invention can flow on the straight flow table and the reversing flow table. The reversing flow table can also carry the flow plate for lateral translation along the transverse guide rail, and finally realize the closed-loop flow of the flow plate along the first flow line and the second flow line. Each straight flow table in the present invention can correspond to an installation station. The flow plate on the straight flow table is the bearing member of the smart sofa base. The smart sofa base is fixed on the rotating table of the flow plate by a clamp. The rotating table can realize 360-degree free rotation, which is convenient for workers to freely adjust the installation angle during the installation process. Since the flow plates on the straight flow table and the reversing flow table need to flow synchronously, the residence time of the flow plate on the straight flow table and the reversing flow table is the same, which requires the installation process of each installation station to be deployed, and the installation time required for each station is as consistent as possible, so as to improve the assembly efficiency as much as possible. By using the assembly method of the assembly line of the present invention to produce smart sofas, the time required for installation at a single workstation can be significantly reduced. The time it takes to produce a sofa on the entire assembly line is the installation time of a single workstation, so the production efficiency of the sofa can be significantly improved. At the same time, the installation procedures required by the workers at a single workstation are significantly reduced, the technical requirements for the workers are also greatly reduced, and the training time for the workers can be significantly reduced.

[0011] Furthermore, the rotating table includes a first layer of plates, a second layer of plates, and a pillar that fixes the two layers of plates, a turntable bearing is connected between the first layer of plates and the flow plate, a plurality of arc-shaped slots are provided at the edge of the first layer of plates, and an arc plate is rotatably provided on the flow plate, and the arc plate can be engaged with or separated from the slots by rotating. When the arc plate is rotated to be completely separated from the slots, the arc plate can no longer constrain the first layer of plates, so the rotating table can rotate freely in this state; when the arc plate is rotated to be partially or completely engaged with any slot, the rotating table is fixed and cannot rotate. Workers generally need to fix the rotating table during assembly.

[0012] Furthermore, the clamp includes a shaft body vertically rotatably arranged between the first layer and the second layer, a large gear coaxially fixed on the shaft body, a lever rotatably sleeved on the shaft body, a torsion spring connected between the lever and the shaft body, a plurality of small gears rotatably arranged on the first layer, an eccentric rod eccentrically arranged on the small gear, and a limit block arranged on the upper end of the eccentric rod, the small gears are meshed with the periphery of the large gear in a circular array, the second layer is provided with a window for the eccentric rod to pass through, the limit block is located on the upper side of the second layer, and the first layer is provided with a lever constraint assembly for fixing the lever.

[0013] The present invention can realize the rapid positioning or releasing of the sofa base through the above technical scheme. Specifically, the clamp in the present invention is suitable for fixing a circular base. The base to be fixed is placed on the upper side of the second layer. At this time, the limit blocks are all located on the inner side of the base. By flipping the lever, the large gear can be driven to rotate synchronously, and then all the small gears can be driven to reverse synchronously. Since the eccentric rod on the small gear is eccentrically set, the radius of the circumscribed circle defined by several limit blocks will change with the rotation during the rotation. As the radius of the circumscribed circle defined by the limit blocks increases, all the limit blocks will eventually abut against the inner side of the base at the same time and completely fix the base. At this time, the lever constraint assembly needs to fix the position of the lever. In the present invention, the lever and the shaft body are connected by a torsion spring. The function of the torsion spring is that when the torsion force of the lever is less than the minimum deformation force of the torsion spring, the lever and the shaft body are rigidly connected. When the torsion force of the lever is greater than the minimum deformation force of the torsion spring, the torsion spring can prevent the shaft body from being overloaded by its own deformation.

[0014] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The production of smart sofas through the assembly method of the assembly line of the present invention can significantly reduce the time required for installation at a single workstation. The time it takes for the entire assembly line to produce a sofa is the installation time of a single workstation, so the production efficiency of the sofa can be significantly improved. At the same time, the installation procedures required by workers at a single workstation are significantly reduced, and the technical requirements for workers are also greatly reduced, which can significantly reduce the training time for workers; 2. In order to facilitate workers to adjust the orientation of the installation object during the installation process, the present invention is provided with a rotating table, which is convenient for rotating the installation object to the desired angle and fixing it; 3. The clamp in the present invention is suitable for fixing a circular base, and can realize rapid positioning or release of the sofa base. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1: See Figure 1 , a smart sofa production line, including 7 flow plates 100, 6 straight flow tables 200 and two reversing flow tables 300;

[0026] See 4, the circulation plate is also provided with a rotating table 400, and the rotating table is provided with a clamp for clamping and fixing the base of the smart sofa;

[0027] See Figure 2 and Figure 3The linear flow turntable is composed of a bracket 210, a horizontal conveying assembly 220 and two guide plates 230. The flow plate can be placed flat on the horizontal conveying assembly and between the two guide plates. The horizontal conveying assembly can push the flow plate to move along the length direction of the guide plate. The horizontal conveying assembly includes a plurality of rotating shafts 221 arranged on the bracket at the same height, three bearing chains 222 distributed at equal intervals, a transmission chain 223 and a first motor 224. A plurality of sprockets 225 are arranged on the rotating shaft. The bearing chain cooperates with the sprocket. The transmission chain is used to drive and connect any one of the rotating shafts and the output shaft of the first motor.

[0028] See Figure 7 and Figure 8 The reversing flow table is provided with a transverse guide rail 310 laid on the ground, a roller 320 rolling on the guide rail, and a reversing power assembly 330 driving the roller to roll on the basis of the linear flow table. The roller is provided at the bottom of the bracket. The distribution direction of the transverse guide rail is perpendicular to the transmission direction of the horizontal transmission assembly. The reversing power assembly is provided on the bracket. The reversing power assembly is composed of a second motor 331 and a transmission chain. The transmission chain is used to transmit the output shaft and the roller of the second motor. The horizontal transmission assembly on the reversing flow table can transmit the flow plate to each other with the horizontal transmission assembly on the linear flow table.

[0029] The straight flow turntables are divided into two groups and placed end to end in the longitudinal direction to form a first flow line and a second flow line that are distributed in reverse parallel. The two reversing flow turntables are respectively arranged at the two ends of the two flow lines.

[0030] The flow plate in this embodiment can flow on the straight flow table and the reversing flow table. The reversing flow table can also carry the flow plate for lateral translation along the transverse guide rail, and finally realize the closed-loop flow of the flow plate along the first flow line and the second flow line. Each straight flow table in this embodiment can correspond to an installation station. The flow plate on the straight flow table is the bearing member of the smart sofa base. The smart sofa base is fixed on the rotating table of the flow plate by a clamp. The rotating table can achieve 360-degree free rotation, which is convenient for workers to freely adjust the installation angle during the installation process. Since the flow plates on the straight flow table and the reversing flow table need to flow synchronously, the residence time of the flow plate on the straight flow table and the reversing flow table is the same, which requires the installation process of each installation station to be deployed, and the installation time required for each station is as consistent as possible, so as to improve the assembly efficiency as much as possible. By using the assembly line assembly method of this embodiment to produce smart sofas, the time required for installation at a single workstation can be significantly reduced. The time it takes to produce a sofa on the entire assembly line is the installation time at a single workstation, so the production efficiency of the sofa can be significantly improved. At the same time, the number of installation procedures required by workers at a single workstation is significantly reduced, the technical requirements for workers are also greatly reduced, and the training time for workers can be significantly reduced.

[0031] See Figure 4 and Figure 5 The turntable includes a first plate 410, a second plate 420 and a support 430 that fixes the two plates together. A turntable bearing 440 is connected between the first plate and the flow plate. Four arc-shaped slots 411 are provided on the edge of the first plate. An arc plate 110 is provided on the flow plate for rotation. A handle 111 is provided on the arc plate. The arc plate can be engaged or separated with the slot when rotated. When the arc plate is rotated to be completely separated from the slot, the arc plate can no longer constrain the first plate, so the turntable can rotate freely in this state; when the arc plate is rotated to be partially or completely engaged with any slot, the turntable is fixed and cannot rotate. Workers generally need to fix the turntable during assembly.

[0032] See Figure 5 The fixture includes a shaft body 510 vertically rotatably arranged between the first layer plate and the second layer plate, a large gear 520 coaxially fixed on the shaft body, a lever 530 rotatably sleeved on the shaft body, a torsion spring 540 connected between the lever and the shaft body, four small gears 550 rotatably arranged on the first layer plate, an eccentric rod 560 eccentrically arranged on the small gears, and a limit block 570 arranged on the upper end of the eccentric rod. The small gears are meshed with the periphery of the large gear in a circumferential array. A window 421 for the eccentric rod to pass through is provided on the second layer plate. The limit block is located on the upper side of the second layer plate. A lever restraint assembly 580 for fixing the lever is provided on the first layer plate.

[0033] See Figure 6 The lever restraint assembly is composed of a ratchet 581, a pawl 582, a pull rod 583, a slider 584 and an L-shaped slot 585. The ratchet is coaxially sleeved on the shaft and fixedly connected to the lever. The pawl is rotated on the first layer and automatically deflects to one side of the ratchet by setting a torsion spring. The pull rod connects the slider and the pawl. The L-shaped slot is set on the first layer, and the slider is slidably assembled in the L-shaped slot. When the slider slides to the far end bending position on the L-shaped slot, the pawl is pulled by the pull rod to separate from the ratchet, and the ratchet can rotate freely; conversely, the pawl is unidirectionally meshed with the ratchet, and the ratchet can rotate unidirectionally.

[0034] The embodiment can realize the rapid positioning or releasing of the sofa base through the above technical scheme. Specifically, the clamp in the embodiment is suitable for fixing a circular base. The base to be fixed is placed on the upper side of the second layer. At this time, the limit blocks are all located on the inner side of the base. By flipping the lever, the large gear can be driven to rotate synchronously, and then all the small gears can be driven to reverse synchronously. Since the eccentric rod on the small gear is eccentrically set, the radius of the circumscribed circle defined by several limit blocks will change with the rotation during the rotation. As the radius of the circumscribed circle defined by the limit blocks increases, all the limit blocks will eventually abut against the inner side of the base at the same time and completely fix the base. At this time, the lever constraint assembly can fix the lever at this position. In the embodiment, the lever and the shaft body are connected by a torsion spring. The function of the torsion spring is that when the torsion force of the lever is less than the minimum deformation force of the torsion spring, the lever and the shaft body are rigidly connected. When the torsion force of the lever is greater than the minimum deformation force of the torsion spring, the torsion spring can prevent the shaft body from being overloaded by its own deformation.

[0035] The present invention can be modified in various ways which are obvious to those skilled in the art, and such modifications are not considered to depart from the scope of the present invention. All such modifications which are obvious to those skilled in the art are intended to be included within the scope of the present claims.
