Description

Technical Field

[0001] This utility model relates to a positioning device for nailing seats and an intelligent nailing machine for seats, belonging to the field of seat nailing technology. Background Technology

[0002] In seat manufacturing, seat cushion edging and nailing is an important process. It refers to wrapping the edges of the seat cushion with a specific edging material (such as fabric, leather, etc.) and fixing it to the seat cushion by nailing, so as to increase the aesthetics, durability and comfort of the seat cushion.

[0003] Typically, before nailing the edging material to the cushion, the edging material needs to wrap around the edge of the cushion and fit tightly to its surface. This not only helps maintain the cushion's structural stability during use but also prevents the edging material from being damaged by friction or pulling, ensuring the cushion maintains its original state and extending its lifespan. In actual processing, operators usually use their hands to pull the edging material to fit the cushion edge, while a nailing machine secures this portion of the edging material to the cushion. However, this process has several drawbacks. First, manually pulling the edging material makes it difficult to ensure a perfect fit, easily leading to misalignment, wrinkles, and other problems that affect the cushion's overall appearance and durability. Furthermore, the tightness of the edging material pulled by the operator may vary at different times, resulting in inconsistent finished cushions. Second, manually pulling the edging material requires physical strength, and prolonged operation can lead to operator fatigue, thus affecting processing efficiency and product quality. Meanwhile, the operators were pulling on the edge-binding material while nailing, which posed a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device and an intelligent nailing machine for seats, which improves processing quality and efficiency and ensures processing safety.

[0005] This utility model is achieved through the following technical solution.

[0006] A positioning device for nailing seats includes:

[0007] frame;

[0008] A receiving mechanism is provided on the frame, and the receiving mechanism is provided with a receiving groove for placing a seat cushion;

[0009] The propulsion mechanism has a movable propulsion component disposed around the edge of the receiving groove. The movement of the propulsion component allows it to switch between a first position entirely outside the receiving groove and a second position at least partially above the receiving groove. During the switching from the first position to the second position, the propulsion component is used to push the edging material toward the surface of the cushion, so that the edging material fits tightly against the surface of the cushion.

[0010] The positioning mechanism has multiple positioning elements located above the receiving groove. The positioning elements are movable up and down and are used to temporarily position the edging material that is closely attached to the surface of the seat cushion on the seat cushion.

[0011] As a further improvement of this utility model, the end of the positioning member near the seat cushion is provided with a sharp part, which is used to penetrate the edging material located below the corresponding positioning member and enter the seat cushion.

[0012] As a further improvement of this utility model, a clearance groove is provided on the propulsion component corresponding to each of the positioning members. The clearance groove is formed at one end of the propulsion component near the receiving groove, and multiple clearance grooves are spaced apart. When the propulsion component is in the second position, the sharp part passes through the corresponding clearance groove and temporarily fixes the edging material to the seat cushion.

[0013] As a further improvement of this utility model, the frame is provided with a pressing mechanism, the pressing mechanism including a first driver, a pressure rod driven by the first driver, and a pressure plate disposed at the bottom end of the pressure rod for pressing the cushion. The first driver is used to drive the pressure rod to rise and fall vertically, and a plurality of positioning members are arranged around the pressure plate.

[0014] As a further improvement of this utility model, the positioning mechanism includes a plurality of second drivers, each of which is provided with a connecting component. The connecting component is provided with at least one of the positioning elements. The second driver is located on the pressure rod and is used to drive the connecting component to move up and down.

[0015] As a further improvement of this utility model, the connecting assembly includes a first connecting member connected to the second driver and a second connecting member for mounting the positioning member, the second driver being hinged to the first connecting member, and the first connecting member being hinged to the pressure plate.

[0016] As a further improvement of this utility model, the propulsion mechanism includes a plurality of third actuators, and the propulsion assembly includes a plurality of propulsion components spaced apart, with one third actuator corresponding to each propulsion component. The third actuators are used to drive the propulsion components to move.

[0017] As a further improvement of this utility model, the lower side of the propulsion component has a pressing plane parallel to the upper surface of the cushion, which is used to press the edge material flat on the surface of the cushion when the propulsion component is above the receiving groove.

[0018] A smart seat nailing machine includes a positioning device for nailing seats, a nailing mechanism, a first power mechanism for driving the receiving mechanism to rotate, and a second power mechanism for driving the positioning mechanism to rotate synchronously relative to the receiving mechanism.

[0019] The beneficial effects of this utility model are:

[0020] 1. Before nailing the seat cushion edging, a pushing component is used to move the edging material, ensuring that all the edging material adheres tightly to the surface of the seat cushion. Then, multiple positioning components are used to temporarily fix the edging material to the seat cushion surface, ensuring that the edging material remains in close contact with the seat cushion surface during nailing. Compared to the existing method where the operator pulls part of the edging material while nailing, this method avoids the displacement of other parts of the edging material that may be caused by manual pulling, ensuring the stability of the edging material's position during nailing. This helps maintain the flatness and consistency of the edging material before and after nailing, improving product quality. Furthermore, it eliminates the need for the operator to pull the edging material while nailing, reducing the operator's workload and safety hazards during nailing.

[0021] 2. The end of the positioning piece near the seat cushion is designed with a sharp point to penetrate the edging material located below it and into the seat cushion. This temporarily secures the edging material to the surface of the seat cushion, preventing it from shifting relative to the cushion under external force during nailing. This ensures the edging material remains in close contact with the cushion throughout the nailing process, improving the quality of the finished product. Furthermore, after nailing, the positioning piece can be moved upwards to easily remove it from the seat cushion.

[0022] 3. When the positioning component temporarily fixes the edge binding material to the seat cushion, the positioning component will not come into contact with the propulsion component, that is, it will not interfere with the position switching of the propulsion component. At the same time, since the clearance groove is formed at the end of the propulsion component near the receiving groove, the edge binding material at the position in contact with the positioning component can be tightly attached to the surface of the seat cushion, ensuring that the edge binding material located between the positioning component and the edge of the seat cushion can be tightly attached to the seat cushion.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0032] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0033] Example 1:

[0034] A positioning device for nailing seat edging, used to accurately position the seat cushion (m) and the edging material (g) during the nailing process. (Refer to...) Figures 1-7The device includes a frame 1, a receiving mechanism 2, a pushing mechanism 3, and a positioning mechanism 4. The receiving mechanism 2 has a receiving groove 21 for placing a cushion m. The shape of the receiving groove 21 is adapted to the shape of the cushion m, that is, the receiving groove 21 is used to limit the position of the cushion m. The pushing mechanism 3 has a moving pushing component arranged around the edge of the receiving groove 21. The movement of the pushing component allows the pushing component to switch between a first position completely outside the receiving groove and a second position at least partially above the receiving groove. During the process of switching from the first position to the second position, the pushing component is used to push the edging material g towards the surface of the cushion m, so that the edging material g can be tightly attached to the surface of the cushion m. The positioning mechanism 4 has a plurality of positioning members 41 located above the receiving groove 21. The plurality of positioning members 41 are arranged in a ring. The positioning members 41 can move up and down. The positioning members 41 are used to position the edging material g, which is tightly attached to the surface of the part to be nailed, on the part to be nailed.

[0035] In this embodiment, before nailing the edging of the seat cushion m, a propulsion component is used to move the edging material g, ensuring that all of the edging material g is tightly attached to the surface of the seat cushion m. Then, multiple positioning elements 41 are used to temporarily fix the edging material g, which is tightly attached to the surface of the seat cushion m, ensuring that the edging material g remains tightly attached to the surface of the seat cushion m during nailing. Compared with the existing method where the operator pulls part of the edging material g while nailing, this method avoids the displacement of other parts of the edging material g that may be caused by manually pulling part of the edging material g, ensuring the stability of the position of the edging material g during nailing. This helps maintain the flatness and consistency of the edging material g before and after nailing, improving product quality. Furthermore, it eliminates the need for the operator to perform nailing operations while pulling the edging material g, reducing the operator's workload and safety hazards during nailing operations.

[0036] In this embodiment, the end of the positioning member 41 near the seat cushion m is provided with a sharp part 41a, which is used to penetrate the edging material g located below the corresponding positioning member 41 and enter the seat cushion m. This allows the edging material g to be temporarily fixed to the surface of the seat cushion m, thereby preventing the edging material g from moving relative to the seat cushion m when subjected to external force during the nailing process. This ensures that the edging material g remains in close contact with the seat cushion m throughout the nailing process, improving the product quality after nailing. Simultaneously, after the nailing operation is completed, the positioning member 41 can be controlled to move upwards, thereby pulling the positioning member 41 out of the seat cushion m, making the operation convenient.

[0037] In this embodiment, the nailing position is located between the positioning member 41 and the edge of the cushion m. Therefore, when the positioning member 41 is inserted into the cushion m, there is a clearance between the positioning member 41 and the edge of the cushion m, thereby preventing the position of the positioning member 41 from interfering with the nailing operation. Furthermore, after nailing is completed, the excess binding material g can be trimmed off, so that the portion of the binding material g pierced by the sharp part 41a will not affect the quality of the product.

[0038] In this embodiment, a clearance groove 33 is provided on each positioning member 41 propulsion assembly. The clearance groove 33 is formed on the end of the propulsion assembly near the receiving groove 21, and multiple clearance grooves 33 are spaced apart. When the propulsion assembly is in the second position, the sharp part 41a of the positioning member 41 passes through the corresponding clearance groove 33 and temporarily fixes the edge material g to the seat cushion m. Therefore, when the positioning member 41 temporarily fixes the edge material g to the seat cushion m, the positioning member 41 will not contact the propulsion assembly, that is, it will not interfere with the position switching of the propulsion assembly. At the same time, since the clearance groove 33 is formed on the end of the propulsion assembly near the receiving groove 21, the edge material g at the position in contact with the positioning member 41 can be tightly attached to the surface of the seat cushion m, ensuring that the edge material g located between the positioning member 41 and the edge of the seat cushion m can be tightly attached to the seat cushion m.

[0039] In this embodiment, a pressing mechanism 5 is provided on the frame 1. The pressing mechanism 5 includes a first driver 52, a pressing rod 53 driven by the first driver 52, and a pressing plate 51 located at the bottom of the pressing rod 53 for pressing the seat cushion m. The first driver 52 is used to drive the pressing rod 53 to rise and fall vertically. The first driver 52 can be an electric telescopic rod, a cylinder, or other components that can drive the pressing rod 53 to rise and fall vertically. Multiple positioning elements 41 are arranged around the pressing plate 51. During operation, the first driver 52 drives the pressing rod 53 to fall vertically, thereby causing the pressing plate 51 to contact the seat cushion m, thereby pressing the seat cushion m onto the receiving groove 21. The pressing plate 51 applies a continuous pressing force to the surface of the seat cushion m to fix the position of the seat cushion m, thereby effectively preventing the seat cushion m from shifting or shaking during the nailing process, ensuring that the seat cushion m remains in a fixed position, ensuring the accuracy of the nailing position, and helping to improve the quality of the product. Furthermore, the pressure plate 51 is positioned above the central area of ​​the receiving groove 21. When the pressure plate 51 presses down on the cushion m, the pressure plate 51 contacts the central area of ​​the cushion m, allowing the pressure of the pressure plate 51 to be evenly distributed on the cushion m. This not only helps to more effectively fix the cushion m, but also prevents the cushion m from deforming or being damaged due to excessive local pressure during the nailing process.

[0040] In this embodiment, the positioning mechanism 4 includes a plurality of second actuators 42, each of which is provided with a connecting component 43, and each connecting component 43 is equipped with a plurality of positioning elements 41. The plurality of second actuators 42 are mounted on the pressure rod 53 via a connecting disc 55, which is sleeved on the outer surface of the pressure rod 53. The second actuators 42 are used to drive the connecting component 43 to move. By mounting the plurality of second actuators on the pressure rod 53 via the connecting disc 55, the positioning mechanism 4 can be integrated onto the pressure rod 53 without interfering with the vertical movement of the pressure rod 53. This eliminates the need for an additional structure to install the positioning mechanism 4, resulting in lower production and manufacturing costs for this device.

[0041] More specifically, the connecting assembly 43 includes a first connecting member 431 connected to the second driver 42 and a second connecting member 432 for mounting the positioning member 41. The movable end of the second driver 42 is hinged to one end of the first connecting member 431, and one end of the first connecting member 431 is connected to the second connecting member 432. The middle portion of the first connecting member 431 is hinged to the upper surface of the pressure plate 51. Thus, upward movement of the movable end of the second driver 42 can cause the positioning member 41 to move downward, and downward movement of the movable end of the second driver 42 can cause the positioning member 41 to move upward. In this structure, the connecting assembly 43 is mounted using a hinge, allowing it to maintain a stable state during vertical movement, reducing the risk of damage and improving its service life. It should be noted that the movable end of the second driver 42 refers to the movable component within the second driver 42, such as the telescopic rod in an electric telescopic rod.

[0042] In this embodiment, the propulsion mechanism 3 includes a plurality of third actuators 32 and a propulsion assembly. The propulsion assembly includes a plurality of spaced-apart propulsion components 31, and a third actuator 32 is configured for each propulsion component 31. The third actuator 32 is used to drive the propulsion component 31 to move, that is, to control the corresponding propulsion component 31 to move, thereby enabling the propulsion assembly to switch between a first position and a second position. The third actuator 32 here can be an electric telescopic rod or a cylinder.

[0043] In this embodiment, the lower side of the pushing member 31 has a pressing plane parallel to the upper surface of the seat cushion m. When the pushing member 31 moves from the outside of the receiving groove 21 to the inside of the receiving groove 21, the pressing plane is used to press the edge material g onto the surface of the seat cushion m when the pushing member 31 is above the receiving groove 21. At the same time, in order to ensure that the edge material g can be tightly attached to the surface of the seat cushion m, the distance between the pressing plane and the upper surface of the seat cushion m is slightly smaller than the thickness of the edge material g, so that the edge material g can be fully squeezed between the pushing member 31 and the seat cushion m, ensuring that the edge material g can be tightly attached to the surface of the seat cushion m.

[0044] Example 2:

[0045] A smart nailing machine for seats, used for nailing and binding the edges of seat cushions (m), as shown in the reference. Figures 1-7 The system includes a positioning device for nailing a seat, a nailing mechanism 6, a first power mechanism 7 for driving the receiving mechanism 2 to rotate, and a second power mechanism. The second power mechanism drives the pressure plate 51 to rotate synchronously with the receiving mechanism 2 when the receiving mechanism 2 rotates. When the seat cushion m and the pressure plate 51 rotate synchronously, the pressure plate 51 can stably fix the seat cushion m, preventing it from shifting or shaking during the nailing process. This helps ensure the accuracy of the nailing position and reduces errors caused by the movement of the seat cushion m. At the same time, the synchronous rotation of the seat cushion m and the pressure plate 51 helps reduce wear between the seat cushion m and the pressure plate 51, and improves the service life of the seat cushion m and the pressure plate 51.

[0046] In this embodiment, a mounting base 54 is provided between the first driver 52 and the pressure rod 53. The pressure rod 53 is rotatably mounted on the mounting base 54. A second power mechanism is connected to the pressure rod 53 to drive it to rotate. The pressure rod 53 is rotatably mounted on the mounting base 54 through bearings. When the first driver 52 is working, it can drive the mounting base 54 to move up and down, thereby driving the pressure rod 53 connected to the mounting base 54 to move up and down, realizing the lifting and lowering of the pressure plate 51, so that the pressure plate 51 can be fixed to the seat cushion m base. It should be noted that the second drive mechanism here is a stepper motor, whose shaft is connected to the pressure rod 53. When working, it can drive the pressure rod 53 to rotate, thereby driving the pressure plate 51 connected to the pressure rod 53 to rotate.

[0047] Meanwhile, since the positioning mechanism 4 is mounted on the pressure rod 53 via the connecting plate 55, when the pressure rod 53 rotates, it drives the positioning mechanism 4 mounted on the pressure rod 53 to rotate accordingly. Therefore, when the seat cushion m rotates under the drive of the first drive mechanism, the positioning part 41 inserted into the seat cushion m can rotate synchronously with the seat cushion m, ensuring the relative fixation of the seat cushion m and the edging material g, so that the edging material g can always be tightly attached to the surface of the seat cushion m when nailing.

[0048] In this embodiment, the frame 1 is provided with at least one vertically extending slide rail 91. A sliding member 92 is provided for each vertical slide rail 91 mounting base 54. The sliding member 92 is slidably connected to the slide rail 91. The slide rail 91 provides guidance for the movement of the mounting base 54, helping to improve the accuracy of the movement. Simultaneously, the sliding member 92 is provided with a groove extending along the sliding direction. The slide rail 91 is slidably embedded in the groove, ensuring that the sliding member 92 can slide stably on the slide rail 91.

[0049] In this embodiment, the mounting base 54 includes a first mounting plate 541 and a second mounting plate 542. The pressure rod 53 is rotatably mounted on the first mounting plate 541, and the second mounting plate 542 is slidably connected to the slide rail 91. The second power mechanism is mounted on the upper side of the first mounting plate 541. The first mounting plate 541 and the second mounting plate 542 are fixedly connected and perpendicular to each other. The movable end of the first driver 52 is connected to the second mounting plate 542. During operation, the first driver 52 drives the second mounting plate 542 to slide, thereby driving the first mounting plate 541 to move up and down.

[0050] In this embodiment, the receiving mechanism 2 includes a base 23 and a receiving plate 22 disposed on the base 23. A receiving groove 21 is formed on the upper surface of the receiving plate 22. A support rod is provided at the bottom of the base 23, and the top end of the support rod is connected to the center position of the base 23. The support rod is mounted on the frame 1 through a bearing. A second power mechanism is driven and connected to the support rod, and the support rod is positioned on the frame 1 through a bearing. Here, the second power mechanism is a stepper motor, which is located below the base 23 and mounted on the frame 1. The rotating shaft of the stepper motor is driven and connected to the support rod to drive the support rod to rotate. During operation, the second power mechanism drives the support rod to rotate, thereby driving the base 23 to rotate, and then driving the cushion m located in the receiving groove 21 to rotate. Furthermore, the pushing mechanism 3 is disposed on the base 23 of the receiving mechanism 2, so that the position of the pushing mechanism 3 relative to the positioning mechanism 4 does not change.
