Description

Technical Field

[0001] The present invention relates to a positioning device for seat nailing and an intelligent seat nailing machine, belonging to the technical field of seat nailing. Background Art

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

[0003] Generally, before nailing the edge wrapping material to the cushion, it is necessary to wrap the edge of the cushion with the edge wrapping material and closely fit it on the surface of the cushion. When the cushion is in use, it not only helps to protect the structural stability of the cushion, but also makes the edge wrapping material not easily damaged by external forces such as friction or pulling, ensuring that the cushion remains in its original state during use and improving the service life of the cushion. During actual processing, usually an operator uses his hands to pull the edge wrapping material to make it fit the edge of the cushion, and at the same time uses a nailing machine to fix this part of the edge wrapping material to the cushion. In this operation, on the one hand, it is difficult for manual pulling of the edge wrapping material to ensure complete fitting of the edge wrapping material to the edge of the cushion, and problems such as misalignment and wrinkles are likely to occur, affecting the overall aesthetics and durability of the cushion, and the tightness of the edge wrapping material pulled by the operator at different times may be different, resulting in poor consistency of the processed cushions. On the other hand, manual pulling of the edge wrapping material requires a certain amount of physical strength, and performing such operations for a long time is likely to cause fatigue of the operator, thereby affecting the processing efficiency and product quality. At the same time, the operator pulls the edge wrapping material while performing the nailing operation, which has a great potential safety hazard. Summary of the Invention

[0004] The purpose of the present invention is to provide a positioning device for seat nailing and an intelligent seat nailing machine, which improve the processing quality and efficiency and ensure processing safety.

[0005] The present invention is realized by the following technical solutions.

[0006] A positioning device for seat nailing, comprising: A frame; A receiving mechanism, provided on the frame, and the receiving mechanism is provided with a receiving groove for placing a cushion; A propulsion mechanism, having a movable propulsion component disposed around the edge of the accommodating groove, the movement of the propulsion component enabling the propulsion component to switch between a first position entirely outside the accommodating groove and a second position at least partially above the accommodating groove, and during the process of the propulsion component switching from the first position to the second position, it is used to push the edge wrapping material towards the surface of the cushion, so that the edge wrapping material closely adheres to the surface of the cushion.

[0007] A positioning mechanism, having a plurality of positioning members located above the accommodating groove, the positioning members being movable up and down, and the positioning members being used to temporarily position the edge wrapping material closely adhering to the surface of the cushion on the cushion.

[0008] As a further improvement of the present invention, one end of the positioning member close to the cushion is provided as a sharp portion, which is used to penetrate the edge wrapping material located below the corresponding positioning member and penetrate into the cushion.

[0009] As a further improvement of the present invention, an avoidance groove is provided on the propulsion component corresponding to each positioning member, the avoidance groove is formed at one end of the propulsion component close to the accommodating groove, and the plurality of avoidance grooves are arranged at intervals. When the propulsion component is in the second position, the sharp portion passes through the corresponding avoidance groove and temporarily fixes the edge wrapping material to the cushion.

[0010] As a further improvement of the present invention, a pressing mechanism is provided on the frame, the pressing mechanism includes a first driver, a pressing rod driven by the first driver, and a pressing plate provided at the bottom end of the pressing rod and used to press the cushion, the first driver is used to drive the pressing rod to move vertically up and down, and the plurality of positioning members are arranged around the pressing plate.

[0011] As a further improvement of the present invention, the positioning mechanism includes a plurality of second drivers, and a connection component is provided corresponding to each second driver, at least one positioning member is provided on the connection component, the second driver is provided on the pressing rod, and the second driver is used to drive the connection component to move up and down.

[0012] As a further improvement of the present invention, the connection component includes a first connecting member connected to the second driver and a second connecting member for installing the positioning member, the second driving member is hinged to the first connecting member, and the first connecting member is hinged to the pressing plate.

[0013] As a further improvement of the present invention, the propulsion mechanism includes a plurality of third drivers, the propulsion component includes a plurality of spaced propulsion members, and a third driver is configured corresponding to each propulsion member, and the third driver is used to drive the propulsion member to move. As a further improvement of the present invention, the lower side of the propulsion component has a pressing plane parallel to the upper surface of the seat cushion, which is used to flatten the edge wrapping on the surface of the seat cushion when the propulsion component is above the accommodating groove.

[0014] A seat intelligent nailing machine includes a positioning device for seat nailing, a nailing mechanism, a first power mechanism for driving the accommodating mechanism to rotate, and a second power mechanism for driving the positioning mechanism to rotate synchronously relative to the accommodating mechanism in the above technical solution.

[0015] Advantages of the present invention: 1. Before nailing the edge wrapping of the seat cushion, the propulsion component is used to push the edge wrapping to move, so that all the edge wrappings can be closely attached to the surface of the seat cushion. Then, a plurality of positioning members are used to temporarily fix the edge wrapping closely attached to the surface of the seat cushion on the seat cushion, ensuring that the edge wrapping can always be closely attached to the surface of the seat cushion during nailing. Compared with the operation method in the prior art where the operator pulls part of the edge wrapping while nailing, on the one hand, it avoids the displacement of other parts of the edge wrapping that may be caused by the operator pulling part of the edge wrapping, ensures the stable position of the edge wrapping during nailing, helps to maintain the flatness and consistency of the edge wrapping before and after nailing, and improves the product quality. On the other hand, it enables the operator to avoid the nailing operation while pulling the edge wrapping, not only reducing the operation intensity of the operator but also reducing the safety hazards during the operator's nailing operation.

[0016] 2. The end of the positioning member close to the seat cushion is set as a sharp part, which is used to penetrate the edge wrapping located below the corresponding positioning member and penetrate into the seat cushion, so that the edge wrapping can be temporarily fixed on the surface of the seat cushion, thereby avoiding the relative movement of the edge wrapping relative to the seat cushion when the edge wrapping is subjected to an external force during the nailing process, ensuring that the edge wrapping can always be in close contact with the seat cushion during the nailing process, and improving the product quality after nailing. At the same time, after the nailing operation is completed, the positioning member can be controlled to move upward, so as to pull out the positioning member from the seat cushion, and the operation is convenient.

[0017] 3. When the positioning member temporarily fixes the edge wrapping on the seat cushion, the positioning member 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 avoidance groove is formed at the end of the propulsion component close to the accommodating groove, the edge wrapping at the position in contact with the positioning member can be closely attached to the surface of the seat cushion, ensuring that the edge wrapping between the positioning member and the edge of the seat cushion can be closely attached to the seat cushion.

Detailed implementation mode

[0019] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0020] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0021] Embodiment 1: A positioning device for seat nailing, which is used to accurately position the seat cushion m and the edge wrapping g during seat cushion edge nailing. Refer to Figures 1 to 7 , including a frame 1, a containing mechanism 2, a propulsion mechanism 3 and a positioning mechanism 4. The containing mechanism 2 is provided with a containing groove 21 for placing the seat cushion m, and the shape of the containing groove 21 is adapted to the shape of the seat cushion m, that is, the position of the seat cushion m is restricted by the containing groove 21. The propulsion mechanism 3 has a propulsion component that is arranged around the edge of the containing groove 21 and is movable. The movement of the propulsion component enables the propulsion component to switch between a first position that is all located outside the containing groove and a second position that is at least partially located above the containing groove. And during the process of the propulsion component switching from the first position to the second position, it is used to push the edge wrapping g towards the surface of the seat cushion m, so that the edge wrapping g can be closely attached to the surface of the seat cushion m. The positioning mechanism 4 has a plurality of positioning members 41 located above the containing groove 21, and the plurality of positioning members 41 are arranged in a ring shape. The positioning members 41 can move up and down, and the positioning members 41 are used to position the edge wrapping g that is closely attached to the surface of the component to be nailed on the component to be nailed.

[0022] In this embodiment, before stapling the edge of the cushion m, the pushing component is used to push the edging material g to move, so that all the edging materials g can be closely attached to the surface of the cushion m. Then, a plurality of positioning members 41 are used to temporarily fix the edging material g closely attached to the surface of the cushion m on the cushion m, ensuring that the edging material g can always be closely attached to the surface of the cushion m during stapling. Compared with the operation method in the prior art where an operator pulls a part of the edging material g while stapling, on the one hand, it avoids the situation where the displacement of other parts of the edging material g may be caused by manually pulling a part of the edging material g, ensures the stable position of the edging material g during stapling, helps to maintain the flatness and consistency of the edging material g before and after stapling, and improves the product quality. On the other hand, it enables the operator to avoid the stapling operation while pulling the edging material g, which not only reduces the operation intensity of the operator but also can reduce the safety hazards during the stapling operation of the operator.

[0023] In this embodiment, one end of the positioning member 41 close to the 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 penetrate into the cushion m, so that the edging material g can be temporarily fixed on the surface of the cushion m, thereby avoiding the relative movement of the edging material g with respect to the cushion m when an external force is applied during stapling, ensuring that the edging material g can always be in close contact with the cushion m during stapling, and improving the product quality after stapling. At the same time, after the stapling operation is completed, the positioning member 41 can be controlled to move upward, so as to pull out the positioning member 41 from the cushion m, which is convenient for operation.

[0024] In this embodiment, the stapling position is located between the positioning member 41 and the edge of the cushion m. Therefore, when the positioning member 41 penetrates into the cushion m, there is a clearance between the position of the positioning member 41 and the edge of the cushion m, so as to avoid the position of the positioning member 41 interfering with the stapling operation during stapling. And, after stapling is completed, the redundant edging material g can be cut off, so that the part of the edging material g penetrated by the sharp part 41a will not affect the product quality.

[0025] In this embodiment, a relief groove 33 is provided on the pushing component corresponding to each positioning member 41. The relief groove 33 is formed at one end of the pushing component close to the accommodating groove 21, and a plurality of relief grooves 33 are arranged at intervals. When the pushing component is in the second position, the sharp part 41a of the positioning member 41 passes through the corresponding relief groove 33 and temporarily fixes the edging material g and the cushion m. Therefore, when the positioning member 41 temporarily fixes the edging material g on the cushion m, the positioning member 41 will not come into contact with the pushing component, that is, it will not interfere with the position switching of the pushing component. At the same time, since the relief groove 33 is formed at one end of the pushing component close to the accommodating groove 21, the edging material g at the position in contact with the positioning member 41 can be closely attached to the surface of the cushion m, ensuring that the edging material g between the positioning member 41 and the edge of the cushion m can be closely attached to the cushion m.

[0026] 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 provided at the bottom end of the pressing rod 53 and used for pressing the seat cushion m. The first driver 52 is used to drive the pressing rod 53 to move vertically up and down. The first driver 52 can be an electric telescopic rod, a cylinder, or other components capable of driving the pressing rod 53 to move vertically up and down. A plurality of positioning members 41 are arranged around the pressing plate 51. During operation, the first driver 52 drives the pressing rod 53 to move vertically downward, thereby driving the pressing plate 51 to contact the seat cushion m, so as to press the seat cushion m against the accommodating 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, so as to effectively prevent the seat cushion m from shifting or shaking during the nailing process, ensure that the seat cushion m remains in a fixed position, ensure the accuracy of the nailing position, and help improve the product quality. Moreover, the pressing plate 51 is arranged above the central area of the accommodating groove 21. When the pressing plate 51 presses on the seat cushion m, the pressing plate 51 contacts the central area of the seat cushion m, so that the pressure of the pressing plate 51 can be evenly distributed on the seat cushion m. On the one hand, it can fix the seat cushion m more effectively, and on the other hand, it can prevent the seat cushion m from being deformed or damaged due to excessive local pressure during the nailing process.

[0027] In this embodiment, the positioning mechanism 4 includes a plurality of second drivers 42. A connection component 43 is provided corresponding to each second driver 42, and a plurality of positioning members 41 are installed on each connection component 43. The plurality of second drivers 42 are arranged on the pressing rod 53 through a connection plate 55. The connection plate 55 is sleeved on the outer surface of the pressing rod 53. The second driver 42 is used to drive the connection component 43 to move. By arranging the plurality of second drivers on the pressing rod 53 through the connection plate 55, the positioning mechanism 4 can be integrated on the pressing rod 53 without interfering with the up and down movement of the pressing rod 53, so that there is no need for an additional structure to install the positioning mechanism 4, making the production and manufacturing costs of this device lower.

[0028] More specifically, the connecting component 43 includes a first connecting piece 431 connected to the second driver 42 and a second connecting piece 432 for mounting the positioning piece 41. One end of the movable end of the second driver 42 is hinged to one end of the first connecting piece 431. One end of the first connecting piece 431 is connected to the second connecting piece 432, and the middle of the first connecting piece 431 is hinged to the upper surface of the pressure plate 51. Thus, the upward movement of the movable end of the second driver 42 can drive the positioning piece 41 to move downward, and the downward movement of the movable end of the second driver 42 can drive the positioning piece 41 to move upward. In this structure, the connecting component 43 is installed in a hinged form, so that the connecting component 43 can maintain a stable state during the up and down movement, is not easily damaged, and helps to improve its service life. It should be noted that the movable end of the second driver 42 refers to the movable part in the second driver 42, such as the telescopic rod in an electric telescopic rod.

[0029] In this embodiment, the propulsion mechanism 3 includes a plurality of third drivers 32 and a propulsion component. The propulsion component includes a plurality of propulsion parts 31 arranged at intervals. One third driver 32 is configured for each propulsion part 31. The third driver 32 is used to drive the propulsion part 31 to move, that is, the corresponding propulsion part 31 is controlled to move by the third driver 32, so that the propulsion component can be switched between the first position and the second position. The third driver 32 here can be an electric telescopic rod or a cylinder.

[0030] In this embodiment, the lower side of the propulsion part 31 has a pressing plane parallel to the upper surface of the seat cushion m. When the propulsion part 31 moves from the outside of the receiving groove 21 into the receiving groove 21, the pressing plane is used to press the edging g. The pressing plane is used to press the edging g flat on the surface of the seat cushion m when the propulsion part 31 is above the receiving groove 21. At the same time, in order to ensure that the edging g can closely adhere 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 edging g, so that the edging g can be fully squeezed between the propulsion part 31 and the seat cushion m, ensuring that the edging g can closely fit on the surface of the seat cushion m.

[0031] Embodiment 2: A seat intelligent nailing machine is used for nailing and edging the seat cushion m. Refer to Figures 1 to 7The embodiment includes a positioning device for nailing a seat, a nailing mechanism 6, a first power mechanism 7 for driving the accommodating mechanism 2 to rotate, and a second power mechanism. The second power mechanism is used to drive the pressure plate 51 to rotate synchronously with the accommodating mechanism 2 when the accommodating 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, helping to ensure the accuracy of the nailing position and reduce 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, thereby increasing the service life of the seat cushion m and the pressure plate 51.

[0032] 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 the pressure rod 53 to rotate. The pressure rod 53 is rotatably mounted on the mounting base 54 via a bearing. When the first driver 52 is in operation, 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, thereby achieving the raising and lowering of the pressure plate 51, so that the pressure plate 51 can contact the seat cushion m and thus fix the seat cushion m. It should be noted that the second driving mechanism here is configured as a stepping motor, whose rotating shaft is connected to the pressure rod 53. When in operation, it can drive the pressure rod 53 to rotate, thereby driving the pressure plate 51 connected to the pressure rod 53 to rotate.

[0033] At the same time, since the positioning mechanism 4 is installed on the pressure rod 53 through the connecting plate 55, when the pressure rod 53 rotates, the positioning mechanism 4 installed on the pressure rod 53 is driven to rotate accordingly. Therefore, when the seat cushion m rotates under the drive of the first driving mechanism, the positioning member 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 object g, so that the edging object g can always be close to the surface of the seat cushion m when nailing.

[0034] In this embodiment, the frame 1 is provided with at least one vertically extending slide rail 91. A sliding member 92 is provided corresponding to each vertical slide rail 91 mounting seat 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 seat 54, thereby improving the accuracy of the movement of the mounting seat 54. Furthermore, the sliding member 92 is provided with a sliding groove extending along the sliding direction. The slide rail 91 is slidably embedded in the sliding groove, ensuring that the sliding member 92 can slide stably on the slide rail 91.

[0035] 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, 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, and when working, the first driver 52 drives the second mounting plate 542 to slide and drive the first mounting plate 541 to move up and down.

[0036] In this embodiment, the accommodating mechanism 2 includes a base 23, an accommodating plate 22 disposed on the base 23, a accommodating groove 21 formed on the upper surface of the accommodating plate 22, a support rod disposed at the bottom of the base 23, the top end of the support rod being connected to the center of the base 23, the support rod being mounted on the frame 1 via a bearing, a second power mechanism being connected to the support rod, and the support rod being positioned on the frame 1 via a bearing, the second power mechanism being a stepping motor located below the base 23 and mounted on the frame 1, the stepping motor's rotating shaft being connected to the support rod to drive the support rod to rotate, and during operation, the second power mechanism drives the support rod to rotate, thereby driving the base 23 to rotate, and further driving the seat cushion m located in the accommodating groove 21 to rotate. Furthermore, the propulsion mechanism 3 is disposed on the base 23 of the accommodating mechanism 2, so that the position of the propulsion mechanism 3 relative to the positioning mechanism 4 does not change.

[0037] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
