For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figures 1 to 9 As shown, the bed core frame-pinning mechanism of this utility model is used to nail the upper frame 102 and the lower frame 103 to the top and bottom edges of the spring frame 101 respectively to form a bed core. It includes: a frame 1, with a processing station 11 in the middle for nailing the spring frame 101, and hanging parts 12 on each of the four sides of the frame 1 that are higher than the processing station 11; and a nailing module 2, including a clamping gun 21 and a feeding structure 22, the feeding structure 22 being used to feed the clamping gun... 21 provides rolled nail strips, and the clamping gun 21 is used to nail the nail strips to the connection between the spring frame 101 and the upper frame 102 or the lower frame 103; a three-axis drive mechanism 3 is provided on the hanging part 12 of the frame 1 by means of the three-axis drive mechanism 3, and the three-axis drive mechanism 3 can drive the clamping gun 21 to move along the X-axis, Y-axis and Z-axis directions to position the clamping gun 21 to a predetermined nailing position on the edge of the spring frame 101, and keep the feeding structure 22 always extending out of the frame 1.

[0019] See Figure 2 , Figure 3 The frame 1 is frame-shaped, with a processing station 11 in the middle. The upper part of the four sides of the frame 1 is provided with a hanging part 12. In the vertical direction, the hanging part 12 is higher than the height of the processing station 11.

[0020] See Figure 2 , Figure 3 The frame 1 is provided with nailing modules 2 on all four sides. The nailing module 2 includes a clamping gun 21 and a feeding structure 22. The clamping gun 21 and the feeding structure 22 are located on the hanging part 12 of the frame 1 through a three-axis drive mechanism 3. The three-axis drive mechanism 3 can drive the clamping gun 21 from top to bottom to move to the processing station 11 and position it at the nailing position on the edge of the spring mesh frame 101.

[0021] Specifically, when attaching the frame to the spring mesh frame 101 at the processing station 11 of frame 1, the spring mesh frame 101 is first transported to the processing station 11 of frame 1. Then, the frame is placed manually on the top surface of the spring mesh frame 101 so that the frame corresponds to the edge of the top surface of the spring mesh frame 101. The three-axis drive mechanism 3 controls the nailing module 2 along the Y-axis and Z-axis directions so that the clamping gun 21 of the nailing module 2 can be positioned on the edge of the spring mesh frame 101. Then, the clamping gun 21 is driven to move along the X-axis so that the clamping gun 21 can perform nailing operations on the spring mesh frame 101 and the upper frame 102 at the predetermined nailing position. After the four sides of the spring mesh frame 101 are nailed simultaneously, the upper frame 102 and the spring mesh frame 101 can be nailed together. This method has the characteristics of high mechanization and high nailing efficiency. Furthermore, compared to the conventional nailing structure located on the side of the spring mesh frame 101, which is difficult to replace or repair due to being obstructed by the frame body 1, this application hangs the clamping gun 21 and the feeding structure 22 on the hanging part 12 of the frame body 1 through the three-axis drive mechanism 3. This allows the feeding structure 22 to be exposed, making it easier for workers to replace the nail strips. At the same time, when the clamping gun 21 is damaged, the damaged position of the hanging clamping gun 21 is more easily exposed, making it easier to repair.

[0022] In one or more embodiments, the three-axis drive mechanism 3 includes an X-axis linear module 31 disposed on the material hanging part 12, a Y-axis linear module 32 driven to move by the X-axis linear module 31, and a Z-axis linear module 33 controlled to move by the Y-axis linear module 32; wherein, the clamping gun 21 is disposed on the Z-axis linear module 33, and the feeding structure 22 is fixedly disposed on the Y-axis linear module 32 on the side away from the frame 1; the feeding structure 22 is a feeding roller rotatably mounted on the Y-axis linear module 32, and the feeding roller is not driven to move by the Y-axis linear module 32.

[0023] See Figures 2 to 5 When nailing the spring mesh frame 101 and the upper frame 102, firstly, the Z-axis linear module 33 controls the Y-axis linear module 32, the clamping gun 21, and the feeding structure 22 to move down to the nailing position. Then, the Y-axis linear module 32 controls the clamping gun 21 to approach the nailing position of the spring mesh frame 101 and the upper frame 102. Finally, the X-axis linear module 31 controls the Y-axis linear module 32, the Z-axis linear module 33, the clamping gun 21, and the feeding structure 22 to move horizontally synchronously, so that the clamping gun 21 can fix the nail strips horizontally on the spring mesh frame 101 and the upper frame 102. This method has the characteristics of high nailing efficiency and convenient operation, and is practical. It should be noted that the feeding structure 22 is always installed on the side of the Y-axis linear module 32 away from the processing station 11. That is, the feeding structure 22 is always exposed to the outside of the frame 1, so that the staff can replace the nail strips.

[0024] In one or more embodiments, the processing station 11 of the frame 1 is equipped with a conveyor line 4 for conveying the spring mesh frame 101. See also Figure 2 , Figure 3 The conveyor line 4 can transport the un-nailed spring mesh frame 101 to the processing station 11 of the frame 1, and after nailing the spring mesh frame 101 to the upper frame 102, it is output from the processing station 11 of the frame 1, realizing the automated transportation of the spring mesh frame 101; the conveyor line 4 can be a roller conveyor line 4.

[0025] In one or more embodiments, a lifting mechanism 5 is also provided at the processing station 11 of the frame 1. The lifting mechanism 5 is used to lift the spring mesh frame 101 conveyed by the conveyor line 4 to the working height so as to detach it from the conveyor line 4. The lifting mechanism 5 includes a base plate 51, a lifting plate 52 and a lifting assembly 53. The lifting assembly 53 is provided between the lifting plate 52 and the base plate 51 and is used to control the lifting of the lifting plate 52 relative to the base plate 51. Along the conveying direction of the conveyor line 4, the lifting plate 52 is provided with a first sliding plate 54 and a second sliding plate 55 arranged side by side. Along the conveying direction perpendicular to the conveyor line 4, the lifting plate 52 is provided with a rotatable conveyor belt 56. The first sliding plate 54 is fixedly connected to the forward part of the conveyor belt 56 and the second sliding plate 55 is fixedly connected to the return part of the conveyor belt 56.

[0026] See Figure 2 , Figure 3 , Figure 6 , Figure 7 The lifting mechanism 5 includes a base plate 51, a lifting plate 52, and a lifting assembly 53 disposed between the two. The lifting assembly 53 is used to control the lifting plate 52 to rise and fall relative to the base plate 51. In one specific embodiment, the lifting assembly 53 consists of a first rod, a second rod, and a cylinder. The first rod and the second rod intersect to form a scissor fork structure. The cylinder is disposed on the base plate 51 and can drive one end of the first rod to slide relative to the base plate 51, thereby controlling the ends of the first rod and the second rod to move closer together to lift the lifting plate 52, or controlling the ends of the second rod to move away from each other to lower the lifting plate 52. In another specific embodiment, the lifting assembly 53 is a cylinder vertically disposed between the base plate 51 and the lifting plate 52, and the cylinder can directly control the rising and falling of the lifting plate 52.

[0027] See Figure 6 , Figure 7At least one conveyor belt 56 is provided on the lifting plate 52 along the conveying direction perpendicular to the conveyor line 4. A first sliding plate 54 and a second sliding plate 55 are arranged side by side on the lifting plate 52 along the conveying direction of the conveyor line 4. The first sliding plate 54 is fixedly connected to the forward part of the conveyor belt 56, and the second sliding plate 55 is fixedly connected to the return part of the conveyor belt 56. By controlling the conveyor belt 56 to rotate clockwise, the first sliding plate 54 and the second sliding plate 55 can move towards each other, thereby reducing the distance between the edges of the first sliding plate 54 and the second sliding plate 55. By controlling the conveyor belt 56 to rotate counterclockwise, the first sliding plate 54 and the second sliding plate 55 can move away from each other, thereby increasing the distance between the edges of the first sliding plate 54 and the second sliding plate 55. Through this arrangement, the distance between the edges of the first sliding plate 54 and the second sliding plate 55 can be adjusted to meet the nailing requirements of spring mesh frames 101 of different sizes.

[0028] Specifically, when the spring mesh frame 101 is edged, the conveyor line 4 transports the spring mesh frame 101 to the processing station 11 of the frame 1. The lifting component 53 lifts the lifting plate 52, so that the first sliding plate 54 and the second sliding plate 55 can lift the spring mesh frame 101 on the conveyor line 4, so that the spring mesh frame 101 is separated from the conveyor line 4 and lifted to the working height. Then, the three-axis drive mechanism 3 controls the nailing module 2 to nail the upper edge 102 to the side of the spring mesh frame 101.

[0029] In one or more embodiments, along the conveying direction of the conveyor line 4, the frame 1 is provided with two sets of first centering mechanisms 6, and along the conveying direction perpendicular to the conveyor line 4, the frame 1 is provided with two sets of second centering mechanisms 7. The first centering mechanisms 6 and the second centering mechanisms 7 cooperate to push and limit the four sides of the spring mesh frame 101. The first centering mechanism 6 includes a base plate 62 pushed by a first driving device 61, a second driving device 63 disposed on the base plate 62, and a first push plate 64 vertically driven to rise and fall by the second driving device 63. The second centering mechanism 7 includes a third driving device 71 disposed on the frame 1 and a second push plate 72 driven to move laterally by the third driving device 71. The first driving device 61, the second driving device 63 and the third driving device 71 can all be cylinders.

[0030] See Figure 2 , Figure 3 , Figure 8 , Figure 9When the conveyor line 4 transports the spring mesh frame 101 to the processing station 11 of the frame 1, the first centering mechanism 6 and the second centering mechanism 7 are used to center the spring mesh frame 101, reducing the difficulty of nailing the spring mesh frame 101 to the upper frame 102. Specifically, when centering the spring mesh frame 101, the second drive device 63 controls the first push plate 64 to rise above the conveyor line 4, and then the first drive device 61 controls the base plate 62 to move toward the spring mesh frame 101, so that the first push plate 64... The push plate 64 presses against the side of the spring mesh frame 101. At the same time, the third drive device 71 controls the second push plate 72 to move toward the spring mesh frame 101, so that the second push plate 72 presses against the side of the spring mesh frame 101 perpendicular to the conveying direction. By having the two first push plates 64 and the two second push plates 72 press against the four sides of the spring mesh frame 101 simultaneously, the spring mesh frame 101 can be pushed to adjust and center on the conveying line 4. It has the characteristics of high centering efficiency and high centering accuracy, and is practical.
