Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, and in particular to a bed core side butterfly spring nailing device. Background Art

[0002] Spring mattresses are increasingly popular for their comfort, but the edges of spring cores are prone to deformation and collapse. To improve the core's stability, butterfly springs are often used to secure the core. Currently, the butterfly springs in spring cores are manually secured to the edges of the frame and spring strings using a handheld nail gun, or by manually positioning and initially securing the frame before nailing. This process has a low degree of automation, resulting in low efficiency and hindering production processes.

[0003] It should be noted that the above technical background is merely provided to provide a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. Simply because these solutions are described in the technical background section of the present invention, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0004] In order to overcome the above shortcomings, the purpose of the present invention is to provide a bed core side butterfly spring nailing device, thereby effectively solving the above technical problems.

[0005] In order to achieve the above purpose, the technical solution adopted by the present invention is: a bed core side butterfly spring nailing device, including a device body, the device body includes:

[0006] The butterfly spring feeding mechanism includes a material rack for placing the butterfly spring;

[0007] The butterfly spring clamping mechanism includes a material clamping robot, which is used to clamp the butterfly spring and place it on the side of the bed core;

[0008] The bed core conveying mechanism includes a roller conveying line, and the bed core is placed on the roller conveying line for conveyance;

[0009] The bed core positioning and lifting mechanism includes a positioning module and a lifting module. The lifting module is arranged below the positioning module. It can pass through the roller conveyor line to lift the bed core from the roller conveyor line and then reach the positioning module. The positioning module can position and fix the bed core; when the butterfly spring is nailed to the side of the bed core, the bottom of the bed core is on the conveyor line, which is not convenient for the operation of the nailing robot, and the position of the bed core also needs to be ensured to be stable during the nailing process of the bed core; so by arranging a lifting member below the bed core, the bed core is lifted to a position suitable for nailing processing, avoiding collision with the conveyor during nailing, thereby improving processing efficiency; and by arranging a positioning member above the bed core, it plays a role in fixing the bed core when nailing the side of the bed core, avoiding misalignment of nails, and further ensuring the stability of the bed core position.

[0010] The nailing mechanism is arranged above the roller conveyor line and corresponds to the positioning module, and is used for nailing on the side of the bed core to fix the butterfly spring on the side of the bed core; the nailing mechanism includes a plurality of nail guns arranged above the roller conveyor line, each nail gun is connected to a three-axis drive module, and the three-axis drive module can drive the nail gun to move and nail the part of the side of the bed core where the butterfly spring is attached.

[0011] The beneficial effects of the present invention are as follows: the bed core side butterfly spring nailing equipment designed in this scheme can automatically complete the bed core transportation and positioning, butterfly spring loading and butterfly spring nailing on the four sides of the bed core, with a high degree of automation.

[0012] The working process of this equipment is as follows: the bed core is first placed on the roller conveyor line for transportation. When the bed core moves to the bed core positioning and lifting mechanism, the bed core is lifted to a position suitable for nailing by setting a lifting piece under the bed core, and the side of the bed core is positioned by setting a positioning piece above the bed core; at the same time, the clamping robot sticks a row of butterfly springs it has clamped to the side of the bed core, and then the nail gun in the nailing mechanism, driven by the three-axis drive module, nails and fixes the part of the bed core side where the butterfly spring is attached.

[0013] Furthermore, the material rack is set on the turntable and is evenly distributed around the turntable, and the butterfly springs are stacked on the material rack; the turntable can rotate under the drive of the motor, and the material rack on the turntable changes position with the turntable. Butterfly springs are stacked on each material rack, which can achieve uninterrupted feeding. The clamping module takes out the butterfly springs stacked on the material rack to realize automatic loading. When the butterfly springs on one material rack are taken out, the rotation of the turntable can allow another full material rack to move to the material taking area of ​​the clamping module.

[0014] Furthermore, a double-axis clamping module and a cache rack are provided on one side of the turntable, and a plurality of positioning grooves arranged in a straight line are provided on the cache rack, and the butterfly springs are placed in the positioning grooves; a cache area is provided on one side of the turntable material rack, and the butterfly springs on the material rack are first clamped out by the double-axis clamping module and placed on the cache rack in the cache area, and a plurality of positioning grooves arranged in a straight line are provided on the cache rack, and a butterfly spring is placed in one positioning groove. When a row of positioning grooves are full of butterfly springs, the clamping robot can clamp out all the butterfly springs on the cache rack at one time, which can improve the efficiency of material retrieval, and at the same time, a row of butterfly springs taken out can be nailed to the side of the bed core at one time; the double-axis clamping module includes a clamp and a double-axis drive module, and the double-axis drive module can drive the clamp to move horizontally and lift, so that the clamp can take the butterfly spring out of the material rack and put it into the cache rack.

[0015] Furthermore, the material-grabbing end of the material-grabbing robot includes a mounting plate, on which a number of clamping blocks arranged in a straight line are provided, the clamping blocks are arranged corresponding to the positioning slots on the cache rack, and one clamping block clamps one butterfly spring; when the material-grabbing robot takes materials from the cache rack, the clamping blocks on the mounting plate can take out the butterfly springs in the positioning slots, and one clamping block takes out the butterfly springs from one positioning slot. The clamping blocks arranged in a straight line can take out a row of butterfly springs at one time, and directly stick the butterfly springs to the side of the bed core, and then the nailing mechanism nails this row of butterfly springs to the side of the bed core in sequence.

[0016] Furthermore, the positioning module includes a first clamping portion and a second clamping portion, the first clamping portion is arranged along the X direction, and the second clamping portion is arranged along the Y direction; the first clamping portion and the second clamping portion are both capable of moving relative to or away from each other to adjust the clamping and positioning of the bed core; the two clamping portions move in two directions respectively to clamp and fix the four sides of the bed core at the same time;

[0017] Furthermore, the roller conveyor line includes two roller conveyors, which are arranged at intervals along the Y direction, and the interval distance is smaller than the width of the bed core along the Y direction. Two conveyors are set to convey the bed core. On the one hand, the spacing between the two conveyors can be adjusted to adapt to bed cores of different widths, which is more practical; the roller conveyor includes active rollers and passive rollers, which are arranged at intervals one by one. The active roller has a driving device, and the passive roller does not have a driving device. The driving device only drives the active roller to rotate. At least one active roller drives the material, and the passive roller plays a supporting role. Reducing the number of driven rollers can simplify energy; the width of the lifting member along the Y direction is smaller than the interval distance between the two roller conveyors along the Y direction, and the interval distance between the two roller conveyors should be slightly larger than the width of the lifting member to facilitate the up and down movement of the lifting member.

[0018] Furthermore, the first clamping part and the second clamping part both include a first base plate and a first push plate, the first base plate is fixed on the truss, the first push plate is connected to the first base plate through a slide rail, and also include a first telescopic cylinder, one end of the first telescopic cylinder is connected to the first push plate, and the other end is fixed on the truss, and the first telescopic cylinder can push the first push plate to move relative to the first base plate.

[0019] The first clamping part and the second clamping part also include a second base plate and a second push plate, the second base plate is fixed to the end of the first base plate, the second push plate is connected to the second base plate through a slide rail, and also include a second telescopic cylinder, one end of the second telescopic cylinder is connected to the second push plate, and the other end is fixed to the second base plate, and the second telescopic cylinder can push the second push plate to move relative to the second base plate.

[0020] Furthermore, the lifting module includes a base, a lifting plate and a scissors fork assembly, one side of the scissors fork assembly is a fixed end, and the other side is a sliding end; the scissors fork assembly is symmetrically arranged on both sides, which supports and balances the bed core, thereby improving the stability of the bed core processing; the upper and lower ends of the fixed end are respectively hinged to the lifting plate and the base through a hinge seat, and the upper and lower ends of the sliding end are respectively provided with an upper sliding guide device and a lower sliding guide device; the upper sliding guide device and the lower sliding guide device also have a limiting function to ensure that after lifting, the upper sliding end and the lower sliding end of the bed core will not slide during the nailing process, and the lifting is always stable; the scissors fork assembly includes two cross-connected lifting rods, which are rotatably connected by a pin shaft; it can ensure stability during the lifting process, stably support the lifting frame above, and thereby ensure the stability of the bed core processing above.

[0021] Furthermore, the roller conveyor line includes a first roller conveyor line and a second roller conveyor line, the first roller conveyor line is perpendicular to the conveying direction of the second roller conveyor line, the end of the first roller conveyor line is connected to the head end of the second roller conveyor line, and a lifting and transferring mechanism is provided at the connecting position of the two; in the entire work process, butterfly springs need to be nailed on all four sides of the bed core, the bed core is nailed with butterfly springs on its left and right sides on the first roller conveyor line, and then the bed core needs to be transferred from the first roller conveyor line to the second roller conveyor line through the lifting and transferring mechanism, and then the butterfly springs are nailed on the front and back sides of the bed core on the second roller conveyor line, thereby completing the work of nailing butterfly springs on the four sides of the bed core.

[0022] Furthermore, the lifting and transferring mechanism includes a bed core support frame, a liftable lifting frame is provided below the bed core support frame, a conveying module is provided on the lifting frame, and the conveying direction of the conveying module is perpendicular to the direction in which the bed core moves to the bed core support frame. When the lifting frame rises to contact the bed core, the conveying module can move the bed core from the first roller conveyor line to the second roller conveyor line; before the bed core is transferred to the bed core support frame, the conveying module on the lifting frame is lower than the bed core support frame; after the bed core is transferred to the bed core support frame, the lifting frame moves upward, driving the conveying module to contact the bed core, and at this time, the conveying module starts working to transfer the bed core to the next workstation.

[0023] Furthermore, it also includes a telescopic drive assembly and a lifting assembly disposed on the frame, wherein the lifting assembly includes a lifting turret hinged to the frame and the lifting bracket, and the telescopic drive assembly can drive the lifting turret to rotate about a hinge point formed with the frame to raise and lower the lifting bracket; the telescopic drive member provides power for the raising and lowering of the lifting bracket, and the raising and lowering of the lifting bracket can meet the needs of moving the bed core from the previous station to the bed core support frame, avoiding interference with the bed core during the process of moving it to the bed core support frame. The telescopic drive assembly can be a telescopic cylinder or other known mechanical mechanism that can drive the lifting turret to rotate. This is prior art and will not be elaborated on here.

[0024] Furthermore, the lifting turret includes a first hinged end, a second hinged end, and a third hinged end. The first hinged end is hinged to the lower surface of the lifting bracket, the second hinged end is hinged to the frame, and the third hinged end is hinged to the telescopic drive assembly. The number of lifting turrets in a set of lifting assemblies is not limited and can be 1, 2, or more. During the lifting process, the two sets of lifting assemblies can make the lifting bracket rise and fall more smoothly, avoiding the phenomenon of lifting tilt, thereby ensuring that the bed core can move stably to the next workstation. The articulation of the first and second hinged ends is achieved through bearing seats.

[0025] Furthermore, the conveyor module is connected to the lifting bracket via a conveyor bracket. The conveyor module includes a conveyor chain arranged around the conveyor bracket. The conveyor bracket is height-adjustable via its vertical plates and the lifting bracket to accommodate different types of bed cores. The conveyor bracket is also equipped with a material stop plate parallel to the conveyor chain to ensure the bed core is accurately positioned when transferred to the next workstation.

[0026] Furthermore, the invention also includes several driven gear sets corresponding to the conveying modules, the driven gear sets including upper gears and lower gears that are staggered in the vertical direction. The upper gears are located on the conveying bracket, and the lower gears are correspondingly located on the lifting bracket. The lifting bracket is provided with a driving connecting rod along its length. The driving connecting rods sequentially pass through the lower gears and are connected to their bearings. The conveying chain can pass through and mesh with the upper and lower gears. The rotation of the lower gear drives the conveying chain. The two upper gears can also play an auxiliary driving role in the movement of the conveying chain under the rotation of the lower gear. Thus, the conveying chain can move the bed core to the next station.

[0027] Furthermore, it also includes a conveying drive assembly, which includes a driving motor arranged on the lifting bracket and a driving main gear and a driving slave gear that are meshed with each other.

[0028] Furthermore, the driving connecting rod passes through the driving gear and is connected to its bearing; the linkage between multiple conveying modules is achieved through the driving connecting rod, thereby providing multiple conveying forces for the movement of the bed core to improve the conveying efficiency of the bed core.

[0029] In the entire lifting and transferring mechanism, the bed core support frame, the lifting assembly and the conveying module cooperate with each other. The bed core support frame provides support for the bed core to be transferred to the lifting and transferring location. The conveying module is set at 90 degrees to the initial moving direction of the bed core, that is, the bed core completes a 90-degree track change, so that the two sides of the bed core where the butterfly spring clips are not completed are in the bed core transfer direction, to facilitate the complete clipping of the butterfly spring on the bed core. The lifting assembly can effectively avoid interference with the conveying module during the bed core transfer process. BRIEF DESCRIPTION OF THE DRAWINGS

The operation of the robot is necessary, and during the process of nailing the bed core, it is also necessary to ensure that the position of the bed core is stable; so by arranging a lifting member 4.5 under the bed core, the bed core is lifted to a position suitable for nailing processing, avoiding collision with the conveying member during nailing, thereby improving processing efficiency; and by arranging a positioning member 4.4 above the bed core, when nailing the side of the bed core, it plays a role in fixing the bed core, avoiding misalignment of nails, and further ensuring the stability of the bed core position; it also includes a nailing mechanism 5, which is arranged above the roller conveyor line and is arranged corresponding to the positioning module, and is used for nailing on the side of the bed core to fix the butterfly spring on the side of the bed core; the nailing mechanism 5 includes several nail guns arranged above the roller conveyor line, each nail gun is connected to a three-axis drive module, and the three-axis drive module can drive the nail gun to move and nail the part of the bed core side where the butterfly spring is attached.

[0066] This proposal designs a bed core side butterfly spring nailing device, which can automatically complete the bed core transportation and positioning, butterfly spring loading and butterfly spring nailing on the four sides of the bed core, with a high degree of automation.

[0067] The working process of this equipment is as follows: the bed core is first placed on the roller conveyor line for transportation. When the bed core moves to the bed core positioning and lifting mechanism 4, the bed core is lifted to a position suitable for nailing by setting a lifting piece 4.5 under the bed core, and the side of the bed core is positioned by setting a positioning piece 4.4 above the bed core; at the same time, the clamping robot 2.3 sticks a row of butterfly springs it has clamped to the side of the bed core, and then the nail gun in the nailing mechanism 5, driven by the three-axis drive module, nails and fixes the part of the bed core side where the butterfly spring is stuck.

[0068] In one or more embodiments, Figures 2-4 As shown, the material rack 1.1 is set on the turntable 1.2 and is evenly arranged around the turntable 1.2, and the butterfly springs are stacked and placed on the material rack 1.1.

[0069] The turntable 1.2 can rotate under the drive of the motor. The material rack on the turntable 1.2 changes position with the turntable 1.2. Butterfly springs are stacked on each material rack to achieve uninterrupted feeding. The clamping module takes out the butterfly springs stacked on the material rack to realize automatic loading. When the butterfly springs on a material rack are taken out, the rotation of the turntable 1.2 can allow another full material rack to move to the material taking area of ​​the clamping module.

[0070] In one or more embodiments, a dual-axis clamping module 1.3 and a buffer rack 1.4 are provided on one side of the turntable 1.2. The buffer rack 1.4 is provided with a plurality of positioning slots 1.5 arranged in a straight line, and the butterfly springs are placed in the positioning slots 1.5.

[0071] A cache area is provided on one side of the turntable 1.2 material rack. The butterfly springs on the material rack are first clamped out by the dual-axis clamping module 1.3 and placed on the cache rack 1.4 in the cache area. The cache rack 1.4 is provided with several positioning slots 1.5 arranged in a straight line. A butterfly spring is placed in one positioning slot 1.5. When a row of positioning slots 1.5 are full of butterfly springs, the clamping robot 2.3 can clamp out all the butterfly springs on the cache rack 1.4 at one time, which can improve the efficiency of material retrieval. At the same time, a row of butterfly springs taken out can be nailed to the side of the bed core at one time; the dual-axis clamping module 1.3 includes a clamp and a dual-axis drive module. The dual-axis drive module can drive the clamp to move horizontally and vertically, so that the clamp can take the butterfly spring out of the material rack and place it on the cache rack 1.4.

[0072] In one or more embodiments, the material picking end of the clamping robot 2.3 includes a mounting plate 2.1, and a plurality of clamping blocks 2.2 arranged in a straight line are provided on the mounting plate 2.1. The clamping blocks 2.2 are arranged corresponding to the positioning slots 1.5 on the cache rack 1.4, and one clamping block 2.2 clamps one butterfly spring.

[0073] When the material-clamping robot 2.3 takes materials from the cache rack 1.4, the clamping block 2.2 on the mounting plate 2.1 can take out the butterfly spring in the positioning slot 1.5. One clamping block 2.2 takes out a butterfly spring from one positioning slot 1.5. The clamping blocks 2.2 arranged in a straight line can take out a row of butterfly springs at a time and stick the butterfly springs directly to the side of the bed core. Then the nailing mechanism 5 nails this row of butterfly springs to the side of the bed core in turn.

[0074] In one or more embodiments, Figures 5 to 12 As shown, the positioning module includes a first clamping portion 4.41 and a second clamping portion 4.42. The first clamping portion 4.41 is arranged along the X direction, and the second clamping portion 4.42 is arranged along the Y direction.

[0075] The first clamping portion 4.41 and the second clamping portion 4.42 can move relative to or away from each other to adjust the clamping position of the bed core; the two clamping portions move in two directions respectively to clamp and fix the four sides of the bed core at the same time.

[0076] In one or more embodiments, the roller conveyor line includes two roller conveyors, which are arranged at intervals along the Y direction, and the interval distance is smaller than the width of the bed core along the Y direction. Two conveyors are set to convey the bed core. On the one hand, the spacing between the two conveyors can be adjusted to adapt to bed cores of different widths, which is more practical.

[0077] In one or more embodiments, the roller conveyor includes active rollers and passive rollers, which are spaced apart from each other. The active rollers have a driving device, while the passive rollers do not. The driving device only drives the active rollers to rotate. At least one active roller drives the material, while the passive rollers serve as support. Reducing the number of driven rollers can save energy.

[0078] In one or more embodiments, the width of the lifting member 4.5 along the Y direction is smaller than the distance between the two roller conveyors along the Y direction, and the distance between the two roller conveyors is slightly larger than the width of the lifting member 4.5 to facilitate the up and down movement of the lifting member 4.5.

[0079] In one or more embodiments, the first clamping portion 4.41 and the second clamping portion 4.42 both include a first base plate 4.411 and a first push plate 4.412, wherein the first base plate 4.411 is fixed to the truss 4.3, and the first push plate 4.412 is connected to the first base plate 4.411 via a slide rail 4.417. The first clamping portion 4.41 and the second clamping portion 4.42 further include a first telescopic cylinder 4.4151, wherein one end of the first telescopic cylinder 4.4151 is connected to the first push plate 4.412, and the other end is fixed to the truss 4.3, and the first telescopic cylinder 4.4151 is capable of pushing the first push plate 4.412 to move relative to the first base plate 4.411 toward or away from the bed core.

[0080] In one or more embodiments, at least one of the first clamping portion 4.41 or the second clamping portion 4.42 further includes a second base plate 4.413 and a second push plate 4.414. The second base plate 4.413 is fixed to the end of the first push plate 4.412, and the second push plate 4.414 and the second base plate 4.413 are connected by a slide rail 4.417. The second base plate 4.4152 further includes a second telescopic cylinder 4.4152, one end of which is connected to the second push plate 4.414 and the other end is fixed to the second base plate 4.413. The second telescopic cylinder 4.4152 is capable of pushing the second push plate 4.414 up and down relative to the second base plate 4.413. Therefore, when the mattress core passes through, the second base plate 4.413 retracts without obstructing the passage of the mattress core. After the mattress core passes through, the second base plate 4.413 is pushed out, and at this time, the first push plate 4.412 is pushed out to achieve a push and position against the edge of the mattress core.

[0081] In some embodiments, the second telescopic cylinder 4.4152 and the second push plate 4.414 may be located only on the front and rear sides of the bed core along the direction of transport. Thus, during movement of the bed core, the second telescopic cylinder 4.4152 first retracts the second push plate 4.414. After the bed core passes, the second push plate 4.414 is extended. At this point, the first telescopic cylinder 4.4151 pushes the first push plate 4.412 toward the bed core, thereby effectively positioning the bed core. Alternatively, the second telescopic cylinder 4.4152 and the second push plate 4.414 assembly may not be located on the sides of the bed core (i.e., the sides along the direction of transport of the bed core).

[0082] In one or more embodiments, the lifting module includes a base 4.51, a lifting plate 4.52 and a scissors fork assembly 4.53, one side of the scissors fork assembly 4.53 is a fixed end 4.531, and the other side is a sliding end 4.532; the scissors fork assembly 4.53 is symmetrically arranged on both sides, which supports and balances the bed core, thereby improving the stability of the bed core processing.

[0083] The upper and lower ends of the fixed end 4.531 are hinged to the lifting plate 4.52 and the base 4.51 respectively through hinge seats, and the upper and lower ends of the sliding end 4.532 are respectively provided with an upper sliding guide device and a lower sliding guide device.

[0084] The upper sliding guide device and the lower sliding guide device also have a limiting function to ensure that after lifting, the upper sliding end and the lower sliding end will not slide during the nailing process of the bed core, and the lifting is kept stable.

[0085] The scissor fork assembly 4.53 includes two cross-connected lifting rods 4.534, which are rotatably connected by a pin 4.533; this ensures stability during the lifting process, stably supports the lifting frame above, and thereby ensures stability in the upper bed core processing.

[0086] In one or more embodiments, the roller conveyor line includes a first roller conveyor line 3.1 and a second roller conveyor line 3.2, the conveying directions of the first roller conveyor line 3.1 and the second roller conveyor line 3.2 are perpendicular, the end of the first roller conveyor line 3.1 is connected to the head end of the second roller conveyor line 3.2, and a lifting and transferring mechanism 6 is provided at the connecting portion between the two.

[0087] During the entire work process, butterfly springs need to be nailed to the four sides of the bed core. The butterfly springs are nailed to the left and right sides of the bed core on the first roller conveyor line 3.1, and then the bed core needs to be transferred from the first roller conveyor line 3.1 to the second roller conveyor line 3.2 through the lifting and transferring mechanism 6, and then the butterfly springs are nailed to the front and back sides of the bed core on the second roller conveyor line 3.2, thereby completing the work of nailing butterfly springs on the four sides of the bed core.

[0088] In one or more embodiments, Figures 13 to 16 As shown, the lifting and transferring mechanism 6 includes a bed core support frame 6.2, and a liftable lifting bracket 6.3 is arranged below the bed core support frame 6.2. A conveying module 6.5 is arranged on the lifting bracket 6.3, and the conveying direction of the conveying module 6.5 is perpendicular to the direction in which the bed core moves to the bed core support frame 6.2. When the lifting bracket 6.3 rises to contact the bed core, the conveying module 6.5 can move the bed core from the first roller conveyor line 3.1 to the second roller conveyor line 3.2.

[0089] Before the bed core is transferred to the bed core support frame 6.2, the conveying module 6.5 on the lifting bracket 6.3 is lower than the bed core support frame 6.2; when the bed core is transferred to the bed core support frame 6.2, the lifting bracket 6.3 moves upward, driving the conveying module 6.5 to contact the bed core. At this time, the conveying module 6.5 starts working to transfer the bed core to the next workstation.

[0090] In one or more embodiments, the lifting and transferring mechanism 6 also includes a telescopic drive component 6.41 and a lifting component 6.4 arranged on the frame 6.1, and the lifting component 6.4 includes a lifting rotating frame 6.42 hinged to the frame 6.1 and the lifting bracket 6.3. The telescopic drive component 6.41 can drive the lifting rotating frame 6.42 to rotate around the hinge point formed with the frame 6.1 to make the lifting bracket 6.3 rise and fall.

[0091] The telescopic drive provides power for the lifting and lowering of the lifting bracket 6.3. The lifting and lowering of the lifting bracket 6.3 can meet the needs of moving the bed core from the previous workstation to the bed core support frame 6.2, avoiding interference with the bed core during its movement to the bed core support frame 6.2. The telescopic drive assembly 6.41 can be a telescopic cylinder 4.415 or other known mechanical mechanism that can drive the lifting and rotating frame 6.42 to rotate. This is prior art and will not be described in detail here.

[0092] In one or more embodiments, the lifting and rotating frame 6.42 includes a first hinged end 6.421, a second hinged end 6.422 and a third hinged end 6.423, wherein the first hinged end 6.421 is hinged to the lower surface of the lifting bracket 6.3, the second hinged end 6.422 is hinged to the frame 6.1, and the third hinged end 6.423 is hinged to the telescopic drive assembly 6.41.

[0093] The number of lifting turrets 6.42 in a set of lifting assemblies 6.4 is not limited and can be one, two, or more. During the lifting process, the two sets of lifting assemblies 6.4 can make the lifting bracket 6.3 rise and fall more smoothly, avoiding the phenomenon of lifting tilt, thereby ensuring that the bed core can move stably to the next workstation. The articulation of the hinge end 1 and the hinge end 2 is achieved by the bearing seat 6.7.

[0094] In one or more embodiments, the conveying module 6.5 is connected to the lifting support 6.3 via a conveying support 6.52, and the conveying module 6.5 includes a conveying chain 6.51 arranged around the conveying support 6.52.

[0095] The conveying bracket 6.52 is height-adjustable via the vertical plate and the lifting bracket 6.3 to accommodate different types of bed cores. A stop plate 6.53 parallel to the conveying chain 6.51 is also provided on the conveying bracket 6.52 to ensure the bed core is accurately positioned when it is transferred to the next station.

[0096] In one or more embodiments, the device further includes a plurality of driven gear sets 6.10 corresponding to the conveying modules 6.5, wherein the driven gear sets 6.10 include an upper gear 6.101 and a lower gear 6.102 which are staggered in the upper and lower directions. The upper gear 6.101 is located on the conveying bracket 6.52, and the lower gear 6.102 is correspondingly arranged on the lifting bracket 6.3. A driving connecting rod 6.9 is provided on the lifting bracket 6.3 along its length. The driving connecting rod 6.9 passes through the lower gear 6.102 in sequence and is connected to its bearing. The conveying chain 6.51 can pass through and engage with the upper gear 6.101 and the lower gear 6.102.

[0097] The rotation of the lower gear 6.102 drives the conveyor chain 6.51, and the two upper gears 6.101 can also play an auxiliary driving role in the movement of the conveyor chain 6.51 under the rotation of the lower gear 6.102, so that the conveyor chain 6.51 can move the bed core to the next station.

[0098] In one or more embodiments, a conveying drive assembly 6.6 is further included, wherein the conveying drive assembly 6.6 includes a driving motor 6.61 provided on the lifting bracket 6.3 and a driving main gear 6.62 and a driving slave gear 6.63 meshing with each other.

[0099] In one or more embodiments, the driving connecting rod 6.9 passes through the driving gear 6.63 and is connected to its bearing; the driving connecting rod 6.9 realizes the linkage between multiple conveying modules 6.5, thereby providing multiple conveying forces for the movement of the bed core to improve the conveying efficiency of the bed core.

[0100] In the entire lifting and transferring mechanism 6, the bed core support frame 6.2, the lifting assembly 6.4 and the conveying module 6.5 cooperate with each other. The bed core support frame 6.2 provides support for the placement of the bed core when it is transferred to the lifting and transferring location. The conveying module 6.5 is set at 90 degrees to the initial moving direction of the bed core, that is, the bed core completes a 90-degree track change, so that the two sides of the bed core where the butterfly spring clamps are not installed are in the bed core transfer direction, to facilitate the complete clamping of the butterfly spring on the bed core. The lifting assembly 6.4 can effectively avoid interference with the conveying module 6.5 during the bed core transfer process.
