[0035] Example 1

[0036] like Figure 1-8 As shown, a seat cushion assembly device includes a base plate 12, a positioning device, a glue spraying device, and an edge binding device.

[0037] The positioning device includes a positioning plate 24, which is mounted on the base plate 12 in a way that allows it to be lifted and rotated. The positioning plate 24 is equipped with a suction cup 25 for adsorbing the seat cushion.

[0038] The glue spraying device includes a first glue gun 7, which is located above the positioning plate 24 and is capable of moving laterally and longitudinally, and spraying glue vertically onto the seat cushion 10.

[0039] The edging device includes a roller 271, a second glue gun 35, and a velvet cutting mechanism. The roller 271, the second glue gun 35, and the velvet cutting mechanism are all slidably mounted on the base plate 12. The second glue gun 35 sprays glue onto the velvet 74. The roller 271 adheres the glue-coated velvet 74 to the edge of the seat cushion 10. The velvet cutting mechanism cuts the velvet 74 used for edging to a fixed length.

[0040] This setup enables the automatic application of adhesive and edge binding to the seat cushion 10, greatly improving the assembly efficiency of the seat cushion, reducing the difficulty of seat assembly, and further reducing the company's production and labor costs.

[0041] In this embodiment, the positioning device includes a rotating shaft 23, a first cylinder 26, a first motor 232, a first bracket 21, and a second bracket 22. The first bracket 21 is fixed on the base plate 12, and the second bracket 22 is slidably mounted on the first bracket 21. The cylinder body of the first cylinder 26 is fixedly connected to the first bracket 21, and the telescopic end of the first cylinder 26 is fixedly connected to the second bracket 22. The rotating shaft 23 is vertically arranged and rotatably mounted on the second bracket 22. The rotating shaft 23 is fixedly connected to the positioning plate 24, thereby driving the second bracket 22 to slide vertically on the first bracket 21 through the first cylinder 26. The second bracket 22 completes the lifting and lowering movement of the positioning plate 24 through the rotating shaft 23. The first motor 232 is mounted on the second bracket 22, and the output end of the first motor 232 is connected to the rotating shaft 23 for transmission, thereby driving the positioning plate 24 to rotate through the rotating shaft 23.

[0042] Further preferably, to make the movement of the positioning plate 24 more stable, a third bracket 231 is fixedly installed on the second bracket 22. The bottom of the third bracket 231 is fixedly connected to the second bracket 22, and the top of the third bracket 231 is rotatably connected to the positioning plate 24. The rotating shaft 23 is rotatably connected to the third bracket 231, and the rotating shaft 23 passes through the third bracket 231 and is connected to the positioning plate 24. This arrangement increases the connection area between the positioning plate 24 and the second bracket 22, thereby making the lifting and rotating movements of the positioning plate 24 more stable.

[0043] Further preferably, to make the movement of the second support 22 more stable, four vertically arranged first guide posts 221 are fixedly installed on the second support 22, and four first guide sleeves 222 that match the first guide posts 221 are fixedly installed on the first support 21. The first guide posts 221 pass through the first guide sleeves 222 and are slidably connected. In this way, the lifting movement of the second support 22 is more stable, and the rotation of the second support 22 can be restricted, reducing the impact of the movement of the rotating shaft 23 on the second support 22 and improving the stability of the device.

[0044] Further preferably, for a more compact machine structure, both the first bracket 21 and the second bracket 22 are mounted below the base plate 12, and the positioning plate 24 is located above the base plate 12. The first bracket 21 is connected to the bottom of the base plate 12 via multiple first positioning posts 211. The second bracket 22 is located between the first bracket 21 and the base plate 12. The base plate 12 has a first through hole 121, and the third bracket 231 can extend upward from the first through hole 121 and connect to the bottom of the positioning plate 24. Furthermore, the first through hole 121 matches the positioning plate 24. This arrangement allows the positioning device to be positioned on both the upper and lower sides of the base plate 12, thereby reducing the assembly difficulty of other devices and also reducing the stroke of the first cylinder 26, enabling the positioning device to adjust the height and angle of the positioning plate 24 within a limited space.

[0045] Further preferably, to facilitate the removal of the seat cushion 10 from the suction cup 25, the rotating shaft 23 has a vertically extending second through hole, and the positioning plate 24 has a third through hole 241 at its center. A second cylinder 29 is fixed on the second bracket 22, and the telescopic end of the second cylinder 29 extends from the bottom up through the second through hole and the third through hole 241 before protruding from the positioning plate 24. With this configuration, when removing the seat cushion 10 from the suction cup 25, the second cylinder 29 can be driven to push the seat cushion 10 away from the suction cup 25, thus facilitating the separation of the seat cushion 10 from the positioning plate 24.

[0046] Further preferably, to maintain the posture of the seat cushion 10, a plurality of top pins 26 are installed on the positioning plate 24. The positioning plate 24 has a plurality of first sliding holes. The bottom of each top pin 26 has a downwardly extending threaded end. The threaded end of the top pin 26 passes through the first sliding hole from top to bottom, and a nut is threadedly connected to the threaded end of the top pin 26. With this configuration, by rotating the nut, the top pin 26 can be fixed to the positioning plate 24 or slid along the first sliding hole, thereby adjusting the position of the top pin 26. This allows the positioning device to match seat cushions 10 of various specifications and shapes, and enables the seat cushion 10 to be installed horizontally on the positioning device.

[0047] In this embodiment, the glue spraying device further includes a lateral moving mechanism and a longitudinal moving mechanism. The longitudinal mechanism includes two longitudinally moving self-assemblies symmetrically arranged on both sides of the positioning plate 24. The left and right ends of the lateral moving mechanism are respectively connected to the two longitudinal moving components. The first glue gun 7 is mounted on the lateral moving mechanism.

[0048] More preferably, the longitudinal movement assembly includes a longitudinal movement bracket 51, a longitudinal movement slide rail 55, a longitudinal movement slider 56, two longitudinal mounting seats 59, two longitudinal transmission pulleys 57, and a longitudinal transmission belt 58. The longitudinal movement bracket 51 is fixed on the base plate 12. The longitudinal movement slide rail 55 and the two longitudinal mounting seats 59 are both fixed on the longitudinal movement bracket 51. The two longitudinal mounting seats 59 are arranged one in front of the other. The longitudinal movement slide rail 55 is located between the two longitudinal mounting seats 59. The longitudinal movement slider 56 is slidably mounted on the longitudinal movement slide rail 55. The two longitudinal transmission pulleys 57 are respectively rotatably mounted on the two longitudinal mounting seats 59, and the two longitudinal transmission pulleys 57 are connected by the longitudinal transmission belt 58. The longitudinal transmission belt 58 is fixedly connected to the longitudinal movement slider 56.

[0049] In a further preferred embodiment, to enable the two longitudinally moving sliders 56 to move synchronously, the longitudinal moving mechanism further includes a synchronization component. The synchronization component includes a second motor 53 and a drive shaft 54. The two ends of the drive shaft 54 ​​are respectively connected to the longitudinal transmission belt 58 pulley 57 located on the rear side of the two longitudinally moving components. The second motor 53 is mounted on the longitudinally moving bracket 51 and is connected to the drive shaft 54 ​​for transmission. Thus, the longitudinally moving sliders 56 of the two longitudinally moving components are driven to move synchronously through a drive shaft 54, thereby improving the stability of the device.

[0050] Further preferably, to improve the stability of the transmission of the drive shaft 54, the longitudinal synchronization assembly further includes a first mounting plate 52. Both ends of the first mounting plate 52 are fixedly connected to two longitudinal moving brackets 51, respectively. The first mounting plate 52 is located below the drive shaft 54. Multiple first mounting seats are fixedly mounted on the first mounting plate 52. The drive shaft 54 ​​passes through and is rotatably connected to the multiple first mounting seats. The second motor 53 is mounted on the first mounting plate 52. A first synchronous pulley is fixedly mounted on the drive shaft 54, and a second synchronous pulley is fixedly mounted on the output end of the second motor 53. The first and second synchronous pulleys are connected by a synchronous transmission belt. This arrangement makes the transmission of the drive shaft 54 ​​more stable and also facilitates the installation of the second motor 53. Furthermore, the first mounting plate 52 is connected to the base plate 12 by multiple second positioning posts 50, which support the first mounting plate 52, making it more stable.

[0051] Further preferably, the lateral movement mechanism includes a second mounting plate 61, a third motor 63, a second mounting base 62, a lead screw 64, and a first lateral movement slider 67. The left and right ends of the second mounting plate 61 are fixedly connected to the longitudinal movement sliders 56 of two longitudinal movement components. A first lateral movement rail 66 is fixedly mounted on the second mounting plate 61. The first lateral movement slider 67 is mounted on the first lateral movement rail 66. The third motor 63 is mounted on the second mounting plate 61 via the second mounting base 62. The lead screw 64 is connected to the output end of the third motor 63, and the third motor 63 can drive the lead screw 64 to rotate. The lead screw 64 is threadedly connected to the first lateral movement slider 67. The first glue gun 7 is mounted on the first lateral movement slider 67. With this configuration, the third motor 63 drives the lead screw 64 to rotate, and when the lead screw 64 rotates, it can drive the first lateral movement slider 67 to slide on the first lateral movement rail 66.

[0052] More preferably, two fourth mounting plates are fixedly mounted on the second mounting plate 61, arranged left and right. The lead screw 64 is rotatably connected to the two fourth mounting plates, and the first transverse sliding rail 66 is located between the two fourth mounting plates. This facilitates the installation and positioning of the lead screw 64.

[0053] Further preferably, to ensure the stable movement of the first lateral sliding block 67, the lateral movement mechanism further includes a second lateral sliding rail 68. The second lateral sliding rail 68 is located above the first lateral sliding rail 66, and its left and right ends are respectively fixedly connected to two fourth mounting plates. The first lateral sliding block 67 is fixedly connected to the second lateral sliding block 67, with the second lateral sliding block 67 located above the first lateral sliding block 67. The second lateral sliding block 67 is slidably connected to the second lateral sliding rail 68. The first glue gun 7 is fixed to the second lateral sliding block 67 via a third mounting base, and the lead screw 64 is threadedly connected to the second sliding block. This configuration provides limiters on both the upper and lower sides of the lead screw 64, making the lateral movement of the first glue gun 7 more stable.

[0054] In this embodiment, the edging device includes a fifth mounting plate 31, which is slidably mounted on the base plate 12. The edging device also includes a velvet spraying mechanism. Both the velvet spraying mechanism and the velvet cutting mechanism are mounted on the fifth mounting plate 31. The velvet spraying mechanism is located in front of the velvet cutting mechanism, and the roller 271 is located in front of the velvet spraying mechanism. The velvet 74 spraying device includes a second glue gun 35 and a collection box 36. The second glue gun 35 is mounted on the fifth mounting plate 31, and the collection box 36 is mounted on either the fifth mounting plate 31 or the base plate 12. The collection box 36 is located in the spraying direction of the second glue gun 35, thus collecting the glue sprayed from the second glue gun 35. This configuration enables fixed-length glue spraying, fixed-length glue application, and cutting of the velvet 74, eliminating the need for pre-application of glue, greatly improving the efficiency of edging the seat cushion 10 and reducing the cost of seat cushion manufacturing.

[0055] More preferably, the velvet cutting mechanism includes a cutting blade 33, a fourth motor 333, and a sixth mounting plate 334. The sixth mounting plate 334 is vertically arranged and fixed on a fifth mounting plate 31. A vertically arranged cutting slide rail 331 is fixedly mounted on the sixth mounting plate 334. A cutting slider 332 is slidably mounted on the cutting slide rail 331. A third cylinder for driving the cutting slider 332 to move along the cutting slide rail 331 is mounted on the fifth mounting plate 31. The fourth motor 333 is mounted on the cutting slider 332, and the cutting blade 33 is mounted on the output end of the fourth motor 333. With this configuration, the third cylinder drives the cutting slider 332 to move along the cutting slide rail 331, and the fourth motor 333 drives the cutting blade 33 to rotate, thereby enabling the cutting blade 33 to cut the velvet 74 that has passed through its vertical movement path.

[0056] In a further preferred embodiment, to prevent the velvet 74 from shifting during cutting and to ensure stable cutting of the velvet 74, the velvet cutting mechanism further includes a first clamping plate 341, a second clamping plate 342, and a fourth cylinder 343. The fourth cylinder 343 is mounted on a fifth mounting plate 31 via a fourth mounting base 344. Both the first clamping plate 341 and the second clamping plate 342 are vertically arranged. The first clamping plate 341 is fixed on the fifth mounting plate 31. The second clamping plate 342 is connected to the telescopic end of the fourth cylinder 343, thereby driving the second clamping plate 342 to move closer to or away from the first clamping plate 341 via the fourth cylinder 343. The velvet 74 passes between the first clamping plate 341 and the second clamping plate 342 and then through the vertical movement path of the cutting blade 33. With this configuration, before the velvet 74 is cut, the fourth cylinder 343 drives the second clamping plate 342 to approach the first clamping plate 341, causing the first clamping plate 341 and the second clamping plate 342 to clamp the velvet 74. Then, the cutting blade 33 moves vertically to cut the velvet 74 extending between the first clamping plate 341 and the second clamping plate 342. More preferably, there are two second clamping plates 342, with the first clamping plate 341 located between the two second clamping plate 342 supports. The two second clamping plates 342 are fixedly connected by a plurality of second guide posts. The second guide posts pass through second guide sleeves fixed on the first clamping plate 341, allowing the first clamping plate 341 and the second clamping plate 342 to slide in engagement. This configuration makes the movement of the second clamping plate 342 more stable.

[0057] In a further preferred embodiment, in order to keep the position of the velvet 74 extending from between the first clamping plate 341 and the second clamping plate 342 consistent, the second clamping plate 342 has two positioning parts arranged vertically, and the velvet 74 passes between the two positioning parts, so that the extension position of the velvet 74 is kept constant.

[0058] Further preferred, such as Figure 2-8As shown, in order to stably adhere the sprayed velvet 74 to the edge of the seat cushion 10, the edging device also includes a traction gripper 8 and an adhesive plate 271. The traction gripper 8 is mounted on the second transverse sliding block of the transverse moving mechanism. A fifth mounting base 83 is fixedly mounted on the second transverse sliding block. A fifth cylinder 82 is mounted on the fifth mounting base 83. The traction gripper 8 is mounted on the fifth cylinder 82. The fifth cylinder 82 can drive the traction gripper 8 to move up and down. A sixth cylinder 27 is fixedly mounted on the bottom of the positioning plate 24. The adhesive plate 271 is fixedly connected to the telescopic end of the sixth cylinder 27. The adhesive plate 271 is vertically arranged and located on the outside of the positioning plate 24. Furthermore, a seventh cylinder 43 and a sixth mounting base 42 are installed on the base plate 12. An edge-binding slider is slidably mounted on the sixth mounting base 42. The telescopic end of the seventh cylinder 43 is connected to the edge-binding slider, enabling the seventh cylinder 43 to drive the edge-binding slider closer to or further away from the seat cushion 10. The roller 271 is vertically arranged and rotatably mounted on the edge-binding slider. Furthermore, the roller 271 is a cylindrical brush. Thus, the brush can better match the rear end of the seat cushion 10, allowing the fabric 74 to cover the edge of the seat cushion 10.

[0059] In this embodiment, to facilitate the supply of velvet 74, the device further includes a velvet 74 supply device. The velvet 74 supply device includes a movable frame 91, a turntable 92 rotatably mounted on the top of the movable frame 91, and a positioning shaft 93 vertically arranged at the center of the turntable 92. The velvet 74 roll, which is packaged into a roll, is placed on the turntable 92. The positioning shaft 93 extends out from the center of the velvet 74 roll. The velvet 74 supply device also includes a pressure plate, which is sleeved on the positioning shaft 93 and located on the velvet 74 roll. The top of the positioning shaft 93 has a threaded section, and a nut is threadedly connected to the threaded end of the positioning shaft 93. By tightening the nut, the turntable 92 and the pressure plate clamp the velvet 74 roll, thereby preventing the velvet 74 roll from being scattered during the supply of velvet 74. More preferably, the velvet 74 supply device further includes a first guide shaft and a second guide shaft. Both the first guide shaft and the second guide shaft are vertically arranged and rotatably mounted on the fifth mounting plate 31. The first guide shaft is located in front of the second guide shaft and behind the first clamping plate 341. The first guide shaft and the second guide shaft are staggered. The velvet 74 passes between the first guide shaft and the second guide shaft and then passes through the first clamping plate 341 and the second clamping plate.

[0060] In this embodiment, as Figure 9-11As shown, the chair cushion includes a seat board 10, a velvet cloth 94, a first sponge pad 13, a second sponge pad 14, a third sponge pad 15, a fourth sponge pad 16, a middle sponge pad 17, and a U-shaped covering sponge pad 18. The middle sponge pad 17 and the covering sponge pad 18 have the same thickness, the first sponge pad 13, the second sponge pad 14, the third sponge pad 15, and the fourth sponge pad 16 have the same thickness, and the middle sponge pad 17 and the covering sponge pad 18 are thicker than the first sponge pad 13, the second sponge pad 14, the third sponge pad 15, and the fourth sponge pad 16. The fourth sponge pad 16 has a larger outline than the first sponge pad 13, the second sponge pad 14, and the third sponge pad 15, and the outline of the covering sponge pad 18 is not smaller than the outline of the seat cushion 10; the velvet 94 is attached to the edges of the left, right, and rear ends of the seat cushion 10, and L-shaped angle irons 101 are fixedly installed on the left and right ends of the seat cushion 10. The angle irons 101 include a first folded edge and a second folded edge, wherein the first folded edge is fixed to the seat cushion 10, and the second folded edge is set vertically upward; the seat cushion is arc-shaped, with the left and right ends of the seat cushion curving upward and the middle position of the seat cushion being an arc shape.

[0061] The assembly process of the seat cushion using the above equipment is as follows: First, adjust the position of the top pin 26 of the seat cushion plate 10, and fix the seat cushion plate 10 to the positioning plate 24 by multiple suction cups 25 on the positioning plate 24. All the top pins 26 abut against the bottom of the seat cushion plate 10. Before spraying glue on the velvet 74 for the first time, manually pull out one end of the velvet 74 roll. After the pulled-out velvet 74 passes through the second guide shaft and the first guide shaft, it passes out between the first clamping plate 341 and the second clamping plate 342. Then, the second motor 53 starts to drive the transmission shaft 54 ​​to rotate. When the transmission shaft 54 ​​rotates, it drives the longitudinal moving pulley to rotate. The longitudinal moving pulley drives the longitudinal moving belt 58 to rotate. The moving slider 56 moves, and the longitudinally moving slider 56 drives the lateral moving mechanism to move. During the forward and backward movement of the lateral moving mechanism, the third motor 63 starts to drive the lead screw 64 to rotate. The lead screw 64 drives the first lateral moving slider 67 and the second lateral moving slider 67 to move. The second lateral moving slider 67 drives the traction gripper 8 to move through the fifth cylinder 82. When the traction gripper 8 moves above the part of the velvet 74 extending between the first clamping plate 341 and the second clamping plate 342, the fifth cylinder 82 drives the traction gripper 8 to move down, so that the traction gripper 8 clamps the velvet 74. Then the lateral moving mechanism and the longitudinal moving mechanism move again, and through the traction... The gripper 8 pulls the velvet 74 to move. After being sprayed with glue by the second glue gun 35, the velvet 74 moves between the seat cushion 10 and the bonding plate 271. Then, the sixth cylinder 27 is activated to bring the bonding plate 271 closer to the seat cushion 10. At this time, the end of the velvet 74 sprayed with glue is attached to the edge of the seat cushion 10. Then, the gripper 8 releases the velvet 74, and the fifth cylinder 82 is activated to pull the gripper 8 upward. The first motor 232 drives the positioning plate 24 to rotate through the rotating shaft 23. The positioning plate 24 drives the seat cushion 10 to rotate, continuing to pull the velvet 74 past the second spray gun. The seventh cylinder 43 drives the edge-binding slider to move closer to the seat cushion 10. The edge-binding slider drives the roller... As the roller 271 approaches the seat cushion 10, the roller 271 presses against the side of the velvet 74 that is not coated with glue, ensuring that the velvet 74 is always in contact with the edge of the seat cushion 10. When enough velvet 74 extends from the first clamping plate 341 and the second clamping plate 342, the fourth cylinder 343 is activated, causing the first clamping plate 341 and the second clamping plate 342 to clamp the velvet 74. Then, the cutting blade 33 rotates upward to cut the velvet 74. The first motor 232 continues to run until the velvet 74 cut to a fixed length is in contact with the edge of the seat cushion 10. The fixed-length velvet 74 covers the left, right, and rear ends of the seat cushion 10, while the front end of the seat cushion 10 is exposed.The lateral and longitudinal movement mechanisms drive the first glue gun 7 to move, and the first glue gun 7 activates to spray glue onto the top surface of the seat cushion 10, attaching the first, second, third, and fourth sponge pads to the seat cushion 10. Specifically, the first sponge pad is attached to the left side of the seat cushion 10, the second sponge pad to the right side, the third sponge pad to the rear side, and the fourth sponge pad to the position between the first and second sponge pads on the seat cushion 10. Then, the lateral and longitudinal movement mechanisms drive the first glue gun 7 to move, and the first glue gun 7 activates to spray glue... The foam is sprayed onto the first, second, third, and fourth foam pads. Then, the middle foam cushion is attached to the fourth foam pad. Next, the U-shaped covered foam cushion is attached to the first, second, and third foam pads, with the middle foam cushion filling the central opening of the U-shaped covered foam cushion. Then, the air pump is turned off, the suction cup 25 loses its suction force, and the second cylinder 29 is activated. The telescopic end of the second cylinder 29 extends from the through hole on the positioning plate 24, pushing the middle position of the cushion plate 10, separating the cushion plate 10 from the positioning plate 24. The assembled cushion is then removed from the equipment.
