[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] See attached Figure 1 As shown, a device for automatically assembling a frame of a bed core is used to install a frame 13 on the bed core, including a frame loading and fixing device 2 and an automatic nailing device 4. The frame loading and fixing device 2 is used to load the frame 13, move the frame 13 above the mattress, and fix the frame 13. The mattress and the frame 13 are fixed by nailing through the automatic nailing device 4.

[0024] See attached Figure 2-4 As shown, in some embodiments, the bed core automatic frame assembly device includes a silo 1, which is used to place a frame 13. The silo 1 includes a mobile bracket 11 and a floating wire hanger 12, the floating wire hanger 12 is fixedly mounted on the mobile bracket 11, and the frame 13 is placed on the floating wire hanger 12; the floating wire hanger 12 includes four cantilevers distributed in a rectangular shape, each cantilever is evenly provided with a plurality of positioning slots 122, and one frame 13 is placed in one positioning slot 122.

[0025] The bottom of the mobile bracket 11 is provided with a universal wheel, which can drive the mobile bracket 11 to move. The frame 13 is placed on the floating wire hanger 12, and the mobile bracket 11 is pushed to the specified position. The frame 13 on the floating wire hanger 12 can be taken out through the frame loading and fixing device 2. When the frame 13 on the silo 1 is taken out, it can be removed and replaced with another silo 1 full of frames 13, so that uninterrupted loading can be achieved; the four cantilevers distributed in a rectangular shape correspond to the shape of the frame 13, and the frame 13 can be directly hung on the four cantilevers, and the four cantilevers correspond to the positions of the four corners of the frame 13 respectively. At the same time, positioning slots 122 are provided on the cantilever, and one positioning slot corresponds to one frame 13, so a row of multiple frames 13 can be placed on a group of cantilevers, and the frame loading and fixing device 2 takes the frames 13 one by one when taking materials.

[0026] The frame 13 can be placed in a manner that the upper edge is placed on the upper surface of the cantilever located above and the lower edge is placed on the upper surface of the cantilever located below. The upper surface of the cantilever located below is provided with a plurality of equally spaced blocking plates 121. Positioning slots 122 for positioning the frame 13 are formed between adjacent blocking plates 121, and the height of the blocking plates 121 is greater than the diameter of the frame 13, so that the frame 13 between the blocking plates 121 can be well accommodated in the positioning slots 122, thereby enhancing the positioning effect of the frame 13.

[0027] The upper surface of the cantilever located above is also provided with a positioning slot 122, which is formed by providing a groove on the upper surface of the cantilever, and the depth of the groove is smaller than the diameter of the frame. Part of the frame is accommodated in the groove, which not only limits the frame but also facilitates taking.

[0028] Therefore, by providing the positioning slot 122 on the cantilever, it is convenient to take and place the frame 13, and the placement position of the frame 13 can be stable and controllable.

[0029] See attached Figure 5-7 As shown, in some embodiments, the frame loading and fixing device 2 includes a mechanical arm 21 and a fixing frame 22, the mechanical arm 21 and the fixing frame 22 are connected, and the mechanical arm 21 drives the fixing frame 22 to move. A clamping assembly 23 and an inner support fixing assembly 24 are arranged on the fixing frame 22, the clamping assembly 23 is used to clamp the frame 13 and take it out from the silo 1, and the inner support fixing assembly 24 is used to open the frame 13 from the inside.

[0030] In some embodiments, the clamping assembly 23 includes a clamping claw 233, a clamping claw cylinder 232 and a telescopic cylinder 231. The clamping claw cylinder 232 drives the clamping claw 233 to clamp the frame 13, and the telescopic cylinder 231 drives the clamping claw 233 and the clamping claw cylinder 232 to move.

[0031] In some embodiments, the clamping assembly 23 further includes a guide clamping plate 234 , a clamping slot is defined at the bottom of the guide clamping plate 234 , and the guide clamping plate 234 is disposed parallel to the clamping claw 233 .

[0032] The function of the guide card plate 234 is to assist the clamping claw 233 in clamping the frame 13. When the telescopic cylinder 231 drives the clamping claw 233 to extend and approach the frame 13, the guide card plate 234 and the clamping claw 233 move synchronously, and the steel wire part of the frame 13 enters the card groove of the guide card plate 234. At this time, the clamping component 23 and the frame 13 complete the initial positioning. In this way, when the clamping claw 233 is clamping the frame 13, the frame 13 will not move around, which can effectively ensure that the clamping claw 233 can quickly clamp the frame 13.

[0033] In some embodiments, the inner support fixing assembly 24 includes a wire support plate 242 and an inner support driving cylinder 241, wherein the inner support driving cylinder 241 is connected to the wire support plate 242 to drive the wire support plate 242 to translate; when the clamping assembly 23 clamps the frame 13, the telescopic cylinder 231 first drives the clamping claw 233 to extend and approach the frame 13, and then the clamping claw cylinder 232 drives the clamping claw 233 to clamp the wire part of the frame 13. Under the action of the inner support driving cylinder 241, the wire support plate 242 can drive the frame 13 to open outward, so that the frame 13 remains in an open state, so that the frame 13 can be directly sleeved on the bed core, and there is no need to add a device for opening the frame 13.

[0034] In some embodiments, a positioning clamp 243 is provided at the head of the wire support plate 242, and a circular arc groove is provided on the positioning clamp 243, and the bending part of the frame 13 can be clamped in the circular arc groove. The circular arc groove matches the bending part of the frame 13, and when the support structure supports the frame 13, the force point is selected at the bending part of the frame 13. By setting the inner support fixing component 24, the frame 13 is always in a tight state, which is conducive to positioning the frame 13 above the bed core later.

[0035] In some embodiments, there are multiple groups of clamping components 23, and the positions of the multiple groups of clamping components are adapted to the shape of the frame, so that each group of clamping components 23 can clamp the frame 13 at the same time. On the one hand, the frame 13 can be smoothly transferred to the top of the bed core, and on the other hand, during the nailing process, the multiple groups of clamping components fix the frame 13 to prevent the position of the frame 13 from shifting. At the same time, through the setting of the inner support fixing component 24, the four corners of the frame are fixed, so that the corners of the frame 13 and the corners of the bed core are aligned, and the frame is accurately positioned.

[0036] See attached Figure 8 As shown, in some embodiments, the bed core clamping device 3 includes a front clamping plate assembly 31, a side clamping plate assembly 32 and a lifting drive assembly 33, wherein the front clamping plate assembly 31 includes two symmetrical front clamping plates arranged on the conveyor line, and the two front clamping plates are used to clamp the front and rear sides of the bed core; the front clamping plate drive mechanism drives the two front clamping plates in the front clamping plate assembly 31 to move to clamp the bed core or retract to avoid the bed core.

[0037] The side clamping plate assembly 32 includes two symmetrical side clamping plates arranged on both sides of the conveyor line, and the two side clamping plates are used to clamp the left and right sides of the bed core; the side clamping plate driving module drives the two side clamping plates in the side clamping plate assembly 32 to move to clamp the bed core; the bed core is clamped from the front, back, left and right sides respectively through the cooperation of two symmetrical front clamping plates and two symmetrical side clamping plates, so that the bed core is positioned on the conveyor line, which is convenient for the subsequent installation of the frame 13 and nailing; the two symmetrical front clamping plates located on the conveyor line can be translated and raised and lowered by the front clamping plate driving mechanism, so that the clamping plates can not only clamp the bed core, but also descend and retreat without blocking the normal movement of the bed core on the conveyor line.

[0038] In some embodiments, the positive clamping plate driving mechanism includes a first translation driving assembly, the first translation driving assembly includes a first telescopic motor, and the telescopic end of the first telescopic motor acts on the clamping plate to drive the clamping plate to translate.

[0039] The first translation drive assembly also includes a first guide plate, on which a translation track is arranged, and a clamp is arranged on a movable seat, and the movable seat moves on the translation track; the clamp is driven to translate by a first telescopic motor, and one clamp corresponds to one telescopic motor. During operation, the two front clamps move inward or open outward at the same time; the translation track on the first guide plate can guide and limit the clamp, so that the clamp maintains a straight translation; the two symmetrical front clamps located on the conveyor line can translate by the positive clamp drive mechanism, so that the clamps can clamp the bed core.

[0040] In some embodiments, the lifting drive assembly 33 includes a second telescopic motor, the telescopic end of which is connected to the front splint, and can drive the front splint to lift and lower; the lifting drive assembly 33 also includes a second guide plate, and the second guide plate is also provided with a lifting track, and the front splint is movably provided on the lifting track.

[0041] The front splint is driven to rise and fall by the second telescopic motor, and one front splint corresponds to one telescopic motor. When the bed core needs to be positioned and fixed, the front splint is extended from under the conveyor line by the second telescopic motor. When the bed core installation frame 13 is completed, the second telescopic motor drives the front splint to descend and retreat, so that the next bed core will not be blocked when moving; the translation track on the second guide plate can play a guiding and limiting role for the front splint, so that the splint keeps rising and falling in a straight line.

[0042] In some embodiments, the side clamp block drive module includes a second translation drive device, which has the same structure as the first translation drive assembly and is not described in detail here. The mattress can be accurately positioned by setting the bed core clamping device 3, which is convenient for nailing and fixing the frame 13 later.

[0043] See attached Figure 11-13As shown, the automatic nailing device 4 includes a three-axis driving mechanism 41, on which a fixing mechanism 42 is arranged. The fixing mechanism 42 is connected to the automatic feeding mechanism 43 and the automatic nailing mechanism 44 at the same time. The three-axis driving mechanism 41 can simultaneously drive the automatic feeding mechanism 43 and the automatic nailing mechanism 44 to move synchronously in the X-axis direction, the Y-axis direction and the Z-axis direction through the fixing mechanism 42, so as to realize nailing at different positions of the spring mattress.

[0044] In some embodiments, the three-axis drive mechanism 41 includes an X-axis drive assembly 411, which includes an X-axis guide rod. The X-axis guide rod is parallel to the edge of the mattress, and an X-axis slider is provided on the X-axis guide rod. The X-axis slider slides along the X-axis guide rod under the action of the X-axis motor. The X-axis drive assembly 411 can drive the automatic feeding mechanism 43 and the automatic nailing mechanism 44 to move from one end of the spring mattress frame 13 to the other end, thereby achieving nailing and fixing of the spring mattress frame 13.

[0045] The three-axis driving mechanism 41 includes a Y-axis driving assembly 412, which is fixedly connected to the X-axis slider. When the X-axis slider slides along the X-axis guide rod, it drives the Y-axis driving assembly 412 to slide along the X-axis guide rod. The Y-axis driving assembly 412 includes a Y-axis guide rod, which is parallel to the horizontal plane and perpendicular to the X-axis guide rod. A Y-axis slider is arranged on the Y-axis guide rod, and the Y-axis slider slides along the Y-axis guide rod under the action of the Y-axis motor. Through the setting of the Y-axis driving assembly 412, the horizontal distance between the automatic feeding mechanism 43 and the automatic nailing mechanism 44 and the spring mattress frame 13 is adjusted, so that the automatic nailing mechanism 44 can accurately nail the frame 13 of the spring mattress.

[0046] The three-axis driving mechanism 41 includes a Z-axis driving assembly 413, which is fixedly connected to a Y-axis slider. When the Y-axis slider slides along the Y-axis guide rod, it drives the Z-axis driving assembly 413 to slide along the Y-axis guide rod. The Z-axis driving assembly 413 includes a Z-axis guide rod 4132, which is perpendicular to the horizontal plane. A Z-axis slider 4131 is arranged on the Z-axis guide rod 4132, and the Z-axis slider 4131 slides along the Z-axis guide rod 4132 under the action of the Z-axis motor.

[0047] In some embodiments, the fixing mechanism 42 is connected to the Z-axis slider 4131, and the fixing mechanism 42 is driven to move in the X-axis, Y-axis and Z-axis directions through the joint action of the X-axis driving assembly 411, the Y-axis driving assembly 412 and the Z-axis driving assembly 413.

[0048] In some embodiments, the fixing mechanism 42 includes a first fixing plate 421, the first fixing plate 421 is connected to the Z-axis slider 4131, the length of the first fixing plate 421 in the vertical direction is less than the length of the Z-axis slider 4131 in the vertical direction, and a plurality of connection holes are provided on the first fixing plate 421 and the Z-axis slider 4131, and the first fixing plate 421 and the Z-axis slider 4131 are connected and fixed by fixing pins passing through the connection holes. By providing a plurality of connection holes, the connection position of the first fixing plate 421 and the Z-axis slider 4131 can be changed, so that the height of the first fixing plate 421 in the vertical direction can be adjusted.

[0049] By setting the length of the first fixing plate 421 in the vertical direction to be smaller than the length of the Z-axis slider 4131 in the vertical direction, it is ensured that the upper and lower ends of the first fixing plate 421 can be connected to the Z-axis slider 4131, so that the connection between the first fixing plate 421 and the Z-axis slider 4131 is more firmly established. In addition, the height of the first fixing plate 421 in the vertical direction can be adjusted by connecting the first fixing plate 421 and the Z-axis slider 4131 at different positions, and the height of the first fixing plate 421 can be roughly adjusted. Then, the height of the first fixing plate 421 can be finely adjusted by the Z-axis driving assembly 413. By combining the rough adjustment and the fine adjustment, it is ensured that the automatic nailing mechanism 44 can smoothly nail and fix the mattress.

[0050] In some embodiments, the fixing mechanism 42 includes a second fixing plate 422 fixedly connected to the first fixing plate 421 , one end of the second fixing plate 422 is connected to the first fixing plate 421 , and the other end extends away from the mattress, for fixing the automatic feeding mechanism 43 .

[0051] In some embodiments, the fixing mechanism 42 includes a third fixing plate 423 fixedly connected to the first fixing plate 421, one end of the third fixing plate 423 is connected to the first fixing plate 421, and the other end extends toward the direction close to the mattress, and is used to fix the automatic nailing mechanism 44. The first fixing plate 421 connected to the three-axis driving mechanism 41 is arranged between the automatic feeding mechanism 43 and the automatic nailing mechanism 44, which improves the stability of the connection between the fixing mechanism 42 and the three-axis driving mechanism 41.

[0052] In some embodiments, two second fixed plates 422 are provided, which are respectively connected to the left and right ends of the first fixed plate 421, and the two second fixed plates 422 are arranged in parallel, forming an avoidance space between the two second fixed plates 422. The Y-axis drive assembly 412 and the Z-axis drive assembly 413 are respectively located in the avoidance space between the two second fixed plates 422, so that the nailing device as a whole is relatively compact, and through the arrangement of the two second fixed plates 422, the load-bearing capacity of a single second fixed plate 422 is reduced, the risk of deformation of the second fixed plate 422 is reduced, and the service life of the nailing device is improved.

[0053] See attached Figure 13-17 As shown, in some embodiments, the automatic feeding mechanism 43 includes a wheel assembly 431, and the wheel assembly 431 includes a roller 4311 and a roller 4312, the roller 4312 is rotatably mounted on the roller 4311, and an outer retaining spring 4313 and an inner retaining spring 4314 are respectively provided on both sides of the roller 4312; the outer chuck 4315 is mounted on the roller 4312, and the inner chuck 4316 is mounted on the roller 4312 and is located on the inner side of the outer chuck 4315; the inner chuck 4316 is arranged parallel to the outer chuck 4315 and the center lines coincide with each other, and the distance between the inner chuck 4316 and the outer chuck 4315 is greater than the thickness of the snap disk; when installed, the center position of the snap disk is mounted on the roller 4312, and the snap disk is located between the outer chuck 4315 and the inner chuck 4316. The baffle plate 4319 is sleeved on the roller 4312 and is located outside the outer chuck 4315. The wheel assembly 431 is arranged on the second fixing plate 422, and the second fixing plate 422 is connected to the wheel assembly 431 through the roller 4311.

[0054] In some embodiments, the outer side surface of the inner chuck 4316 and the outer side surface of the outer chuck 4315 are both provided with a group of reinforcing ribs, and each group of reinforcing ribs is provided with a plurality of reinforcing ribs and are evenly distributed around the center line of the connecting shaft. The provision of reinforcing ribs can improve the strength of the inner chuck 4316 and the outer chuck 4315 and improve the stability of the structure. The number of reinforcing ribs in each group is 4 to 8. The inner chuck 4316 and the outer chuck 4315 are both provided with a plurality of weight-reducing holes, and the weight-reducing holes and the reinforcing ribs are spaced apart from each other. The provision of the weight-reducing holes can reduce the body weight of the inner chuck 4316 and the outer chuck 4315, and the weight-reducing holes and the reinforcing ribs are spaced apart from each other, which can reduce the weight while maintaining the strength and stability of the structure.

[0055] In some embodiments, the baffle plate 4319 is locked on the roller 4312 by bolts 4318. Locking the baffle plate 4319 by bolts 4318 can achieve a more stable blocking effect and facilitate disassembly and installation. Two bolts 4318 are symmetrically arranged, and the bolts 4318 are knurled high-head bolts. The knurled high-head bolts can withstand greater tension to ensure the firmness of the connection; and can provide good matching force, so that the connection between the bolt 4318 and the connecting piece is more stable. A fixing ring 4317 is provided on the roller 4311, and the fixing ring 4317 is located on the outside of the baffle plate 4319. The fixing ring 4317 is adjustably locked on the roller 4311. The setting of the fixing ring 4317 can fix the roller 4311.

[0056] A bearing is arranged between the roller 4311 and the roller 4312. The roller 4311 is fixedly connected to the inner ring of the bearing, and the roller 4312 is fixedly connected to the outer ring of the bearing. The arrangement of the bearing can make the rolling between the roller 4311 and the roller 4312 more flexible. The number of bearings can be set to two.

[0057] In some other embodiments, a damper is provided on the roller 4311, and the damper is a rotation damper. The setting of the damper can control the speed of the rotational motion, provide a smooth resistance, and prevent excessive or uncontrolled rotation.

[0058] In some embodiments, the automatic feeding mechanism 43 includes a detection member 432, which is fixed to the second fixing plate 422 by a bracket, and is located on the discharge side of the wheel assembly 431. The detection member 432 is used to detect whether there is a nail strip 6 output. In this embodiment, the nail strip 6 is a C-shaped buckle. When the detection member 432 cannot detect the C-shaped buckle, an alarm can be realized through the control system and materials can be replenished in time to improve production efficiency. The detection member 432 is a photoelectric switch sensor. The photoelectric switch sensor is convenient for the C-shaped buckle in the middle to pass through, which is convenient for detection and has a sensitive detection effect.

[0059] See attached Figure 11-12 As shown, in some embodiments, the automatic feeding mechanism 43 also includes a feeding guide channel 433, one end of the feeding guide channel 433 is arranged close to the wheel assembly 431, and the other end is arranged in the automatic nailing mechanism 44, and the nail strip 6 moves along the feeding guide channel 433 and is transported from the automatic feeding mechanism 43 to the automatic nailing mechanism 44.

[0060] The wheel assembly 431, the automatic nailing mechanism 44 and the feeding guide channel 433 are all inclined and have the same angle with the horizontal plane. The height of the wheel assembly 431 in the vertical direction is higher than that of the automatic nailing mechanism 44. On the one hand, during the transportation of the nail strip 6, the gravity of the nail strip 6 itself can provide power, which is beneficial to the transportation of the nail strip 6; on the other hand, the automatic nailing mechanism 44 nails the mattress at a top-down angle, and the two clamping claws 233 of the automatic nailing mechanism 44 are respectively located on the side and front of the mattress, which is beneficial to the nailing operation.

[0061] In some embodiments, the feeding guide channel 433 includes a feeding guide groove 4331, and the feeding guide groove 4331 is located at one end close to the wheel assembly 431. The nail strip 6 is located in the feeding guide groove 4331, and the width of the feeding guide groove 4331 is greater than the width of the nail strip 6. Under the action of the feeding drive mechanism, the nail strip 6 slides along the feeding guide groove 4331.

[0062] In some embodiments, the feeding guide channel 433 includes a feeding guide rod 4332, which is located at one end close to the automatic nailing mechanism 44. The shape of the feeding guide rod 4332 matches the shape of the nail strip 6. The nail strip 6 abuts against the feeding guide rod 4332 and slides along the direction of the feeding guide rod 4332. For example, in this embodiment, the fixing nail 61 is in a C-shaped buckle shape, and the nail strip 6 can half cover the feeding guide rod 4332. Under the action of the feeding drive assembly, the nail strip 6 can slide along the feeding guide rod 4332.

[0063] The feeding guide rod 4332 can position the nail strip 6 more accurately relative to the feeding guide groove 4331, ensuring that the automatic nailing mechanism 44 can accurately drive and clamp the fixed nail 61; the feeding guide groove 4331 relative to the feeding guide rod 4332 can reduce the friction during the driving process of the nail strip 6, reduce the resistance during the feeding process, and facilitate the feeding. By setting the feeding guide groove 4331 at one end close to the wheel assembly 431 and setting the feeding guide rod 4332 at one end close to the automatic nailing mechanism 44, the accuracy of the position of the fixed nail 61 is guaranteed, and the friction during the feeding process is reduced.

[0064] In some embodiments, the feeding drive assembly is disposed between the feeding guide groove 4331 and the feeding guide rod 4332, and the feeding drive assembly includes a feeding drive motor 434 and a driving shaft 435, and the feeding drive motor 434 can drive the driving shaft 435 to rotate. A driven shaft 436 is disposed on one side of the driving shaft 435, and a gap is left between the driven shaft 436 and the driving shaft 435, and the nail strip 6 passes through the gap, and the driving shaft 435 and the driven shaft 436 clamp the nail strip 6, and the driving shaft 435 conveys the nail strip 6 during the rotation process.

[0065] The automatic feeding mechanism 43 can install the wound buckle disc onto the wheel assembly 431, and realize long-term continuous feeding by pulling the strip-shaped C-shaped buckle. The material replenishment interval is long and the feeding efficiency is high. It can meet the long-term continuous nailing needs of the mattress and provide technical support for the research and development of the fully automatic nailing device 4.

[0066] See attached Figure 18-20 As shown, in some embodiments, the automatic nailing mechanism 44 includes a driving cylinder 441, and the driving cylinder 441 can drive the driving rod 444 to extend and retract through the conductive component 442. A nail pushing component and a clamping component 448 are provided at the end of the driving rod 444. The driving rod 444 can push the fixing nail 61 to move toward the spring mattress through the nail pushing component, and then the fixing nail 61 is clamped by the clamping component 448, so that the fixing nail 61 fixes the mattress and the frame 13 of the mattress.

[0067] In some embodiments, the push pin assembly includes an ejector, which includes a first ejector 445 and a second ejector 446. One end of the first ejector 445 is connected to the driving rod 444, and the other end is connected to the second ejector 446. The second ejector 446 extends in the direction of the fixing pin 61. A groove is provided at one end of the second ejector 446 close to the fixing pin 61, which is used to limit the fixing pin 61, so that the fixing pin 61 is driven in the direction of the spring mattress under the action of the second ejector 446, so that the fixing pin 61 falls off the nail strip 6.

[0068] In some embodiments, the clamping assembly 448 includes two clamping jaws arranged in a mirror-like manner, and the clamping jaws include a clamping portion 4482 and a driving portion 4481. A through hole 4483 is provided between the clamping portion 4482 and the driving portion 4481. A pin passes through the through hole 4483 and is connected to the nail fixing plate 443. The two clamping jaws can swing in opposite directions with the through hole 4483 as the center, and the clamping portion 4482 can clamp the fixing nail 61.

[0069] In some embodiments, the driving portion 4481 is an arc-shaped structure, and the distance between the two driving portions 4481 close to the clamping portion 4482 is relatively large, and the distance between the two driving portions 4481 gradually decreases toward the driving rod 444. Two clamping rollers 447 are arranged side by side at the end of the driving rod 444, and the sum of the diameters of the two clamping rollers 447 is greater than the diameter of the driving rod 444, and is also greater than the distance between the two driving portions 4481 in the natural rotation state. When the clamping roller 447 retracts backward under the action of the driving rod 444, it applies outward pressure to the driving portion 4481, thereby increasing the distance between the driving ends 44811, thereby reducing the distance between the clamping portions 4482, and pressing the fixing nail 61.

[0070] In some embodiments, a guide groove 44821 is provided inside the clamping portion 4482, and the direction and size of the guide groove 44821 are adapted to the fixing nail 61. The fixing nail 61 slides along the guide groove 44821 to the clamping end 44822 during being driven by the second ejector 446. The setting of the guide groove 44821 limits the movement trajectory of the fixing nail 61, ensuring that the fixing nail 61 can be nailed at a preset position.

[0071] The driving rod 444 is connected to the second ejector 446. When the driving rod 444 is driven forward, the second ejector 446 pushes out the fixing nail 61. When the driving rod 444 retracts backward, the driving part 4481 is squeezed by the rolling wheel, so that the clamping part 4482 clamps the fixing nail 61. The process of the driving rod 444 extending and retracting completes two actions, thereby improving the nailing efficiency. The driving rod 444 is driven by the cylinder, replacing the traditional manual nailing, freeing up labor and improving the nailing efficiency.

[0072] In some embodiments, automatic nailing devices are provided on the four sides of the bed core, and the four sides of the bed core are nailed and fixed at the same time, thereby improving the nailing efficiency.

[0073] See attached Figure 9-10 As shown, in some embodiments, the bed core flipping device 5 is used to flip the bed core 180 so as to nail the other side of the bed core. The bed core flipping device 5 includes a mounting base 51, on which a flip bracket 53 is connected via a rotating connection assembly 52, and a flip motor 54 is provided on the mounting base 51, the flip motor 54 is connected to the flip bracket 53, and the flip motor 54 can drive the flip bracket 53 to rotate 180 degrees. The flip bracket 53 includes a first flip bracket, which is rotatably arranged on the mounting base 51; and also includes a second flip bracket, which is rotatably arranged on the mounting base 51, and the first flip bracket corresponds to the second flip bracket up and down and the two flip brackets are synchronously flipped.

[0074] The bed core turning device 5 further includes a clamp transmission assembly 56, which is connected to the turning bracket 53 via a clamp driving assembly 55. Specifically, the clamp transmission assembly 56 includes a first clamp assembly, which is located inside the first turning bracket and can be moved back and forth in the direction of the first turning bracket; and a second clamp assembly, which is located inside the second turning bracket and can be moved back and forth in the direction of the second turning bracket.

[0075] The bed core is clamped by controlling the relative movement of the first clamp assembly and the second clamp assembly, and then the first flip bracket and the second flip bracket are flipped synchronously to drive the bed core clamped by the two clamp assemblies to flip together, thereby realizing 180° automatic flipping of the bed core without manual flipping, with high efficiency and no change in position.

[0076] The fixture drive assembly 55 includes a fixture transmission motor 561, and also includes a clamp seat 562 for clamping the bed core. The clamp seat 562 is provided with a synchronous belt 563 capable of automatic transmission. Under the drive of the fixture transmission motor 561, the synchronous belt 563 rotates to realize the transmission of the bed core. While the bed core is turned over by the fixture assembly, the bed core is also connected to the incoming materials and transported without deviation by the synchronous belt 563. The transmission accuracy is high, which is convenient for docking with processing equipment and improves the efficiency of production and processing.

[0077] A method for automatically assembling a frame of a bed core, wherein the method for automatically assembling a frame of a bed core is to automatically assemble a frame of a bed core by using the automatic assembling frame device of the bed core as described above, and the method for automatically assembling a frame of a bed core comprises the following steps: Step S1: Clamp the sides of the bed core through the bed core clamping device to fix the position of the bed core; the bed core clamping device 3 includes a front clamping plate assembly 31, a side clamping plate assembly 32 and a lifting drive assembly 33.

[0078] Step S2: The frame loading and fixing device 2 transfers the frame 13 from the silo 1 to above the bed core, and fixes the frame 13 through the frame loading and fixing device 2 .

[0079] The frame loading and fixing device 2 includes a clamping assembly 23 and an inner support fixing assembly 24. The clamping assembly 23 is used to clamp the frame 13 and take it out from the silo 1, and the inner support fixing assembly 24 is used to open it from the inside of the frame 13. When the frame loading and fixing device 2 transfers the frame from the silo to the top of the bed core, it does not release it, but keeps the state of grasping and opening it, fixes the frame, and waits for the automatic nailing device to nail. When the automatic nailing device completes the nailing, the frame loading and fixing device 2 releases the frame fixed to the bed core and repeats the operation of step S2.

[0080] Step S3, automatically nailing the fixed bed core and frame 13 by an automatic nailing device, and connecting and fixing the bed core and frame by fixing nails.

[0081] The frame and the bed core are fixed by nailing with an automatic nailing device, which improves the nailing efficiency of the bed core and realizes the automatic assembly of the frame with the bed core.

[0082] There is no order between step S1 and step S2. Step S1 can be performed first and then step S2, or step S2 can be performed first and then step S1, or step S1 and step S2 can be performed simultaneously.

[0083] In some embodiments, the following steps are also included: the bed core is flipped 180 degrees by a bed core flipping device, and steps S1 to S3 are repeated to automatically assemble a bed core frame on the other side of the bed core.

By providing the bed core clamping device and the frame feeding and fixing device as a set, the equipment cost is reduced and the floor space occupied by the setting is also reduced.

[0085] In some other embodiments, two groups of bed core clamping devices and frame feeding and fixing devices are provided, which are respectively located on both sides of the transmission direction of the bed core turning device. The bed core turned over by the bed core turning device is transported to the bed core clamping device on the other side, and the bed core is automatically assembled into a frame on the other side of the bed core. By providing two groups of bed core clamping devices and frame feeding and fixing devices, the bed core automatically assembles the frame in a flow-line manner, thereby improving the efficiency of assembling the frame.
