Description

Technical Field

[0001] This invention relates to the field of furniture manufacturing equipment technology, and in particular to an automatic nailing and assembly production line. Background Technology

[0002] Nail guns are widely used in decoration projects, furniture installation, and home furnishing manufacturing. Using nail guns can replace manual nailing, thus significantly improving work efficiency, reducing the labor intensity of workers, and preventing damage to items that need nailing.

[0003] With advancements in technology and improvements in living standards, wood products have gained increasing attention in fields such as interior design, furniture installation, and home furnishing manufacturing due to their unique advantages, leading to a year-on-year increase in demand. To improve production efficiency, wood products are now produced using modular, prefabricated factory methods.

[0004] In the modular production of wooden products, staples are generally used to connect and secure the structure. Currently, the modular production of wooden products is relatively limited, and the nailing and assembly are primarily done manually. Nailing is typically done manually with a handheld nail gun, followed by manual reloading of staple strips. However, the modular production of wooden structures generally requires various sizes of staples, necessitating the use of different types of nail guns. Manually completing nailing and other operations requires a large workforce, resulting in high labor costs, low production efficiency, high worker fatigue, and a high risk of errors, making it unsuitable for automated processes.

The nailing mechanism 6 includes multiple nailing units, each nailing unit corresponds to the filling of a nail of a certain specification, and each nailing unit can work independently. The stacking mechanism 2 is located at the stacking station and is used for unloading and stacking products.

[0036] like Figure 1 As shown, the conveying mechanism 1 includes an upper conveyor line, which includes a pre-assembly conveyor line 14, a first transverse conveyor line 15, a nailing conveyor line 16, a second transverse conveyor line 17, and a palletizing conveyor line 18. There are multiple pre-assembly conveyor lines 14, which are set up corresponding to the pre-assembly station 11. The first transverse conveyor line 15 is located between the pre-assembly conveyor line 14 and the nailing conveyor line 16, and is used to divert the pre-assembled molds 3 on each pre-assembly conveyor line 14 to each nailing conveyor line 16. There are multiple nailing conveyor lines 16, which are set up corresponding to the nailing station 12. The nailing conveyor line 16 is used to transport the nailed molds 3 to the second transverse conveyor line 17. The second transverse conveyor line 17 is located between the nailing conveyor line 16 and the palletizing conveyor line 18, and is used to transport the molds 3 on each nailing conveyor line 16 to the palletizing conveyor line 18. The conveying mechanism 1 also includes a lower conveying line 19 located below the upper conveying line. The lower conveying line 19 has elevators at both ends and is connected to the pre-assembly conveying line 14 and the palletizing conveying line 18 through the elevators. It is used to return the empty mold 3 to the pre-assembly conveying line 14 to realize the cyclic conveying of the mold.

[0037] In addition, the pre-assembly station 11, the nailing station 12 and the palletizing station 13 are all equipped with a barcode reader 110. The barcode reader 110 is used to identify the electronic tag 37 on the mold 3 and obtain the product model on the mold 3. It can realize automatic nailing assembly of various products and has good compatibility.

[0038] The mold is equipped with an RFID electronic tag. Different molds have different tags. When the mold arrives at the nailing station or the palletizing station, the RFID reader fixed on the conveying mechanism triggers a signal to read the RFID electronic tag and obtain the product model of the current mold. The control system simultaneously obtains the signal and controls the nailing robot to retrieve the corresponding nailing program to complete the nailing operation, and controls the palletizing robot to retrieve the corresponding palletizing program to complete the palletizing operation.

[0039] In this embodiment, the product parts are pre-assembled onto the mold 3 by manual means. Then, the manual control valve group 36 on the mold is activated. The pre-assembly mechanism on the mold automatically fixes the position of each product on the mold, realizing the pre-assembly of the product. Then, the start button of the pre-assembly station is activated, the blocking component of the pre-assembly conveyor line is released, and the conveying mechanism 1 transports the mold 3 to the next station.

[0040] like Figure 4-6 As shown, the positioning mechanism 4 includes a positioning group one and a positioning group two. The positioning group one is used to position the mold 3 in the first direction of the nailing station 12. It includes two sets of clamping cylinders 41 that are respectively arranged at the front and rear ends of the mold 3. Each set of clamping cylinders 41 includes multiple clamping cylinders arranged along the second direction of the mold. In addition, the nailing conveyor line 16 located at the nailing station 12 is also provided with a blocking cylinder 42 that is arranged in the first direction, which can also help position the mold in the first direction.

[0041] Positioning group two is used to position the mold 3 in the second direction at the nailing station 12. It includes side-mounted cylinders 43, and side baffles 44 are provided on both sides of the nailing conveyor line 16. The side baffles 44 are higher than the conveying surface of the nailing conveyor line 16. Multiple side-mounted cylinders 43 are provided along one side of the nailing conveyor line 16. The side-mounted cylinders 43 and the side baffles 44 cooperate to position the mold 3 in the second direction at the nailing station 12. The first direction is the conveying direction of the nailing conveyor line 16, and the second direction is perpendicular to the conveying direction. In this embodiment, two side-mounted cylinders 43 and two side baffles 44 are provided, located at the front and rear ends of the mold 3 in the first direction. After the mold 3 is in position, the two side-mounted cylinders 43 push the mold 3 towards the opposite side baffle 44, thereby ensuring that the mold 3 is always positioned to one side on the conveyor line, ensuring consistent positioning.

[0042] like Figure 2-3As shown, the nailing mechanism 5 includes a nailing robot 51, a rotating assembly 52, and a nail gun quick-change station 53. The nailing robot 51 is located on one side of the nailing conveyor line 16, and its end is equipped with a nail gun fixture 54 movably connected to it. The nail gun quick-change station 53 is located on one side of the nailing robot 51 and includes a quick-change platform and multiple nail gun fixtures 54 located on the quick-change platform. The nail gun fixtures 54 located on the quick-change platform are movably connected to the nailing robot 51 through the rotating assembly 52. ​​The rotating assembly 52 includes a rotating base 521, a drive motor 522, a rotating base 523, and a drive motor 524. A base 521 is located at the end of the nailing robot 51. A drive motor 522 is located on the rotating base 521, and a rotating base 523 is located at its output end. A drive motor 524 is located on the rotating base 523, and a rotating connecting plate 525 is located at its output end. The rotation axis of the output end of the drive motor 522 is perpendicular to the rotation axis of the output end of the drive motor 524, which can drive the nail gun fixture to rotate in two directions. A quick-change flange 1 is located on the rotating connecting plate 525, and a quick-change flange 2 that cooperates with the quick-change flange 1 is located on the nail gun fixture 54, thereby enabling quick replacement of the nail gun.

[0043] In this embodiment, as Figure 1-2 As shown, the nailing assembly module has two nailing mechanisms 5, which are located opposite each other on both sides of the nailing conveyor line 16. Correspondingly, there are also two nailing mechanisms 6.

[0044] like Figure 2 , Figure 7 As shown, multiple nailing units are arranged side-by-side on the nailing table 61, including nailing unit one 62, nailing unit two 63, and nailing unit three 64. The nailing table 61 also has pre-set extension mounting positions 611 for installing the nailing units, accommodating production expansion for different products. The number of nailing units corresponds to the type and quantity of nail gun fixtures on the nail gun quick-change station, and can be expanded according to the nailing needs of the product. Automatic nail loading via the nailing mechanism avoids errors and risks associated with manual loading, improving loading efficiency and further enhancing nailing efficiency.

[0045] Among them, such as Figure 8-11As shown, the loading unit 62 includes a loading base plate 621 and a magazine 622, a pushing mechanism 623, a distributing mechanism 624, a receiving mechanism 625, and a loading mechanism 626 disposed on the loading base plate 621. Multiple magazines 622 are provided, and multiple sets of stacked staples are provided inside each magazine 622. Each set of staples in the magazine 622 includes two staple strips (staple strip one and staple strip two) that are staggered vertically. The pushing mechanism 623 and the receiving mechanism 625 are disposed opposite each other on both sides of the magazine 622. The pushing mechanism 623 is used to push out the staples in the magazine 622 in groups. The receiving mechanism 625 is used to receive the pushed-out staples and feed the separated staples to the loading mechanism 626. The separating mechanism 624 is located on one side of the receiving mechanism 625 and works with the receiving mechanism 625 to separate each group of pushed-out staples into an independent staple strip. The loading mechanism 626 is located on the side of the magazine 622 away from the pushing mechanism 623. It is used to position the nail gun and works with the receiving mechanism 625 to load the staples into the nail gun.

[0046] like Figure 8-9 As shown, multiple magazines 622 are arranged side by side on the magazine base 6222. Each magazine 622 has a feeding port at its bottom, and the feeding ports of each magazine 622 are connected. The pushing mechanism 623 can extend into the feeding port of each magazine 622 to push the staples in groups to the distributing mechanism 624. In order to facilitate the distribution, the discharge end of each magazine 622 is provided with a discharge cavity 6226 that is connected to the feeding port of each magazine 622. The discharge cavity 6226 is used to place at least one group of staples pushed out by the pushing mechanism 623.

[0047] Specifically, the magazine 622 includes a magazine compartment 62211 and a magazine cover 62212 located on top of the magazine compartment 62211. The discharge port is located at the bottom of the magazine compartment 62211. The two side walls of the magazine compartment 62211 are equipped with pin bolts located above the discharge port to support the internal clips. The magazine cover 62212 is detachably connected to the magazine compartment 62211 and can close the top opening of the magazine compartment 62211. When opened, clips can be loaded. The top of the magazine cover 62212 also has a handle for easy removal.

[0048] Multiple magazines 622 are fixedly connected to the magazine base 6222 via a magazine positioning assembly. The magazine positioning assembly includes quick-release clamps 6223 and positioning pins 6224. Magazine mounting plates 62213 are provided on both sides of the magazine compartment 62211. A positioning hole is provided in the middle of the magazine mounting plate 62213. The positioning pin 6224 is provided on the magazine base 6222 and cooperates with the positioning hole to position the magazines 622. Two quick-release clamps 6223 are provided, symmetrically arranged on both sides of the magazines 622. The quick-release clamp 6223 has multiple clamping heads 6225 at its clamping end. The number of clamping heads 6225 is not less than the number of magazines 622. These clamping heads 6225 cooperate with the magazine mounting plate 62213 to fix the magazines 622. In this embodiment, one quick-release clamp 6223 has 623 clamping heads, two of which press against the outer end of the magazine mounting plate 62213, and a third clamping head presses against the inner end of the magazine mounting plate of two magazines 622. The magazine positioning assembly allows for quick installation or removal of the magazines 622, simplifying operation and improving production efficiency.

[0049] Among them, such as Figure 8-10 As shown, the pushing mechanism 623 is mounted on the magazine base 6222 and includes a pushing cylinder 6231 and a pushing plate 6232. The pushing plate 6232 is located at the output end of the pushing cylinder 6231, and pushing rods 6233 are located at both ends of the pushing plate 6232. The pushing rods 6233 can extend into the feeding port of each magazine 622 through the pushing cylinder 6231 to push the staples in groups to the sorting mechanism 624. During pushing, the pushing rods 6233 extend into the feeding port of one magazine 622, and after pushing all the staples in that magazine in sequence, they extend into the feeding port of another magazine 622 to push all the staples in the other magazine.

[0050] like Figure 8-10 As shown, the receiving mechanism 625 includes a feeding cylinder 6251, a receiving component one 6252, and a receiving component two 6253. The feeding cylinder 6251 is mounted on the filling base plate 621, and its output end is provided with a feeding plate 6254. The receiving component one 6252 and the receiving component two 6253 are arranged side by side above the feeding plate 6254. The receiving component one 6252 includes a receiving plate one 62521, and the receiving component two 6253 includes a receiving plate two. 62531, the outer shape of receiving plate one 62521 and receiving plate two 62531 are adapted to the inner groove of the staple strip, and the two are set on the same straight line; when receiving material, receiving plate one 62521 and receiving plate two 62531 are set close to the discharge end of the magazine 622, and respectively receive one staple strip from each group of staples. When feeding material, receiving component one 6252 and receiving component two 6253 are moved to the filling mechanism 626 through feeding cylinder 6251.

[0051] The receiving assembly 6252 also includes a lifting cylinder 62522, a lifting cylinder 62523, and a stop plate 62524. The output end of the lifting cylinder 62522 is provided with a receiving plate 62521. The lifting cylinder 62523 is arranged parallel to the lifting cylinder 62522. The output end of the lifting cylinder 62523 is provided with a stop plate 62524. The stop plate 62524 is attached to the side of the receiving plate 62521 away from the magazine 622, and is used to limit the position of each group of staples on the receiving plate 62521 before the staples are separated. The receiving plate 62521 can also feed the received staple strips into the nail gun magazine through the lifting cylinder 62522; the receiving assembly 6253 also includes the parallel lifting cylinders 62532 and 62533. The output end of the lifting cylinder 62532 is equipped with the lifting cylinder 62533, and the output end of the lifting cylinder 62533 is equipped with the receiving plate 62531. The receiving plate 62531 can feed the received staple strips into the nail gun magazine through the lifting cylinders 62532 and 62533.

[0052] like Figure 8-11 As shown, the material distribution mechanism 624 includes a separation seat 6241 and a separation component and a flipping component disposed on the separation seat 6241. The separation component includes a separation cylinder 6242 and a separation rod 6243. The output end of the separation cylinder 6242 is provided with the separation rod 6243. The separation rod 6243 can push the first code bar in a set of code pins to the receiving plate 62531 through the separation cylinder 6242, so as to separate it from the second code bar in the set of code pins. The flipping component is disposed above the separation component and includes a flipping gripper cylinder 6244. The output end of the flipping gripper cylinder 6244 is provided with a gripper for holding the code pins.

[0053] The material distribution mechanism also includes a pushing cylinder 6245 and an adjusting cylinder 6246. The output end of the pushing cylinder 6245 is provided with an adjusting cylinder 6246, and the output end of the adjusting cylinder 6246 is provided with a separating seat 6241, which is used to adjust the height of the separating seat 6241 to adapt to different separating heights. The pushing cylinder 6245 is located on the filling base plate 621 and is used to push the separating seat 6241 to move it closer to or away from the receiving mechanism 625.

[0054] During material receiving, receiving plate 62521 connects and is level with discharge chamber 6226. Stop plate 62524 rises to stop receiving plate 62521 from the side away from magazine 622. Stop plate 62524, receiving plate 62521, and the end face of discharge chamber form a limiting space for placing staples. Receiving plate 531 is driven to rise a short distance by lifting cylinder 62533 to match the height of the inner groove of staple strip 1. A set of staples in magazine 622 is pushed onto receiving plate 62521 by pushing mechanism 623, controlling the receiving position and preventing staples from falling off receiving plate 62521. At this time, staple strips 1 and 2, vertically interleaved, are placed on receiving plate 1. Push cylinder 6246 is activated, carrying... When the moving separator 6241 approaches the receiving assembly 6252, the separator cylinder 6242 drives the separator rod 6243 to extend, pushing the first tack strip at the upper end onto the second receiving strip 62531. Then, the stop plate 62524 descends and resets. At the same time, the receiving plate 62521 rises to the clamping height of the flipping gripper cylinder 6244 under the action of the lifting cylinder 62522. The flipping gripper cylinder 6244 flips the second tack strip 180° and places it on the receiving plate 62521, so that the inner groove opening of the second tack strip is facing down and fitted onto the receiving plate 62521, realizing the separation and arrangement of a set of tack strips. Then, the separation mechanism 624 resets, and the receiving plate 62521 descends to be flush with the second receiving plate 62531, waiting for filling.

[0055] like Figure 8-11 As shown, the loading mechanism 626 includes a nail gun positioning component 6261, a cover opening component 6262, and an unlocking component 6263. The nail gun positioning component 6261 is used to position the nail gun. In this embodiment, the nail gun positioning component includes two support seats that support both ends of the nail gun body. The nail gun can be transferred to the nail gun positioning component by the nailing robot 51.

[0056] The unlocking component 6263 is used to unlock the nail gun bottom cover. It includes a support base 62631 and a rotary clamping cylinder 62632. The support base 62632 is located on the loading base plate 621, and the rotary clamping cylinder 62632 is located above it. The output end of the rotary clamping cylinder 62632 is provided with a pressing head 62633. When the pressing head 62633 is pressed down, the nail gun bottom cover is unlocked. After the nail gun bottom cover is unlocked, the nail gun magazine can be opened through the opening component.

[0057] The cover opening assembly 6262 is located on one side of the nail gun positioning assembly 6251 and is used to open or close the nail gun magazine. It includes a linear module 62621, a cover opening seat 62622, and a cover opening gripper cylinder 6263. The linear module 62621 is located on the loading base plate 621, and its output end is provided with the cover opening seat 62622. The top of the cover opening seat 62622 is provided with the cover opening gripper cylinder 6263, and the output end of the cover opening gripper cylinder 6263 is provided with grippers for holding the bottom cover of the nail gun.

[0058] During loading, receiving plates 62521 and 62531 are moved to the position directly below the nail gun magazine via the feeding cylinder 6251. Then, the pressing head 62633 remains pressed down to unlock the nail gun bottom cover, and the opening assembly pulls the bottom cover backward to open the magazine. Receiving plates 62521 and 62531 rise simultaneously to feed two staple strips into the magazine. Then, receiving plates 62521 and 62531 descend sequentially, and the corresponding opening assembly pushes the bottom cover forward in three sections to completely push the staple strips into the magazine. Finally, the pressing head 62633 and the receiving mechanism 625 reset, and the nail gun bottom cover is locked again, realizing fully automatic loading of staple strips and improving production efficiency.

[0059] The nailing mechanism of this invention can automatically load nails. It can not only automatically load various conventional pneumatic nail guns, but also be used in various automated production lines that require nailing for fully automated production. This avoids errors caused by manual loading and the risks of manual operation, and improves nailing efficiency.

[0060] In addition, such as Figure 4-6 As shown, to accommodate nailing at different positions, the nailing assembly module also includes a lifting mechanism 7 mounted on the nailing conveyor line 16. The lifting mechanism 7 includes a drive motor 71 and a lifting seat 72. Two lifting seats 72 are provided, located at opposite ends of the mold 3 in the first direction. Two sets of clamping cylinders 41 are respectively mounted on one lifting seat 72 and can move with the lifting seat 72, thus not affecting the positioning of the mold 3. Furthermore, the top of the lifting seat 72 is provided with a protruding positioning boss 721, which is positioned along the second direction of the mold 3 (perpendicular to the conveying direction). The bottom of the mold 3 has a long groove that mates with the positioning boss 721, allowing the positioning boss 721 to be inserted into the long groove. In this embodiment, the long groove is the same as the groove of the aluminum alloy beam itself, making the connection between the lifting seat 72 and the mold 3 tighter and preventing the mold from shifting during lifting.

[0061] Each lifting seat 72 is connected to a drive motor 71 via a transmission assembly 73, which drives the lifting seat 72 to move up and down. The transmission assembly 73 includes a transmission shaft 731, a gear 732, a gear 733, and a rack 734. The drive motor 71 has symmetrically arranged transmission shafts 731 at both ends. One end of the transmission shaft 731 is connected to the output end of the drive motor 71 via a universal joint, and the other end is equipped with a gear 732. The gear 733 is located diagonally above the gear 732 and is connected to the gear 732 via gear transmission. The rack 734 is located on one side of the gear 733 and is connected to the gear 733 via gear transmission. The rack 734 is fixedly connected to the lifting seat 72. The gear 733 is located on the transmission shaft 735. The two ends of the transmission shaft 735 are respectively equipped with a support seat 736 and a bearing seat 737 supporting the transmission shaft 735. The support seat 736 and the bearing seat 737 are both located on the nailing conveyor line 16.

[0062] Each lifting seat 72 is further provided with a guide assembly 74 between it and the nailing conveyor line 16. The guide assembly 74 is used to guide the movement of the lifting seat 72 and includes a rail mounting plate 741 at both ends of the lifting seat 72. The rail mounting plate 741 is provided with at least one set of sliding groups. In this embodiment, the rail mounting plate 741 is provided with two sets of sliding groups. The sliding groups include a linear bearing 742 and a rail 743 slidably connected to the linear bearing 742. The rail 743 is provided on the rail mounting plate 741 and is arranged parallel to the rack 734. The linear bearing 742 is provided on support seat one 736 or support seat two 744. Support seat two 744 is provided on the nailing conveyor line 16, and support seat two 744 and support seat one 736 are respectively provided at both ends of the lifting seat 72.

[0063] Drive motor 71 drives transmission shaft 731 to rotate. Through gear transmission, it drives rack to move up and down, thereby driving lifting seat 72 to move up and down. At the same time, guide component 74 guides the movement of lifting seat 72. The overall structure is stable, making mold lifting stable and smooth. Lifting mechanism 7 can drive mold 3 to move up and down. After mold 3 rises a certain distance, the nailing robot can extend under the mold to nail the bottom of the product. It can also nail from the top and sides of the mold, making operation more convenient and realizing all-round automatic nailing and assembly operations.

[0064] The nailing assembly module of the present invention can automatically load and nail, avoiding errors caused by manual loading and the risks of manual operation, and improving production efficiency.

[0065] In addition, such as Figure 4-5As shown, the above-mentioned automatic nailing assembly production line also includes an air supply mechanism 8. The air supply mechanism 8 includes an air connection component. The pre-assembly station 11, the nailing station 12, and the palletizing station 13 are all equipped with air connection components. The air connection components are used to connect to an external air source to supply or release air to the pre-assembly mechanism on the mold, thereby allowing the pre-assembly mechanism to fix or release the product. The air connection component includes a connecting cylinder 81 located on the side of the nailing conveyor line 16. The output end of the connecting cylinder 81 is equipped with a plug socket 82. The plug socket 82 is equipped with a quick plug 83. The mold 3 is equipped with a quick plug 35 that is connected to the plug 83 for air supply. The quick plug 83 is connected to an external air source through an air pipe, and the quick plug 35 is connected to the air passage on the mold 3 through an air pipe.

[0066] The air supply mechanism 8 also includes a control component, which includes a connecting cylinder 2 84 and a pusher plate 85. The connecting cylinder 2 84 is located on the side of the nailing conveyor line 16, and its output end is provided with a pusher plate 85. The mold 3 is provided with a manual control valve group 36 for controlling the air supply and deactivation of the pre-assembly mechanism. The pusher plate 85 can activate the manual control valve group 36 through the connecting cylinder 2 84.

[0067] In this embodiment, control components are only set at the nailing station 12 and the stacking station 13 to automatically control the start of the manual control valve group 36. At the pre-assembly station, since the material is loaded manually, the start of the manual control valve group 36 is also manually controlled.

[0068] Specifically, the air connection assembly can also be used to position the mold. When the positioning reaches the corresponding station, the connecting cylinder 81 drives the quick plug 83 to quickly insert into the quick plug 35 on the mold 3, so as to supply or release air to the pre-assembly mechanism on the mold, thereby allowing the pre-assembly mechanism to fix or release the product.

[0069] The manual control valve assembly 36 is used to supply and cut off air to the cylinders of the pre-assembly mechanism. In this embodiment, it mainly supplies air to the rotary cylinders one and two of the pressing component. When the products pre-assembled in the mold 3 are different, the cylinders of the pre-assembly mechanism may also be different. The manual control valve assembly 36 has a pressure holding function. Therefore, during the conveying process from the pre-assembly station 11 to the nailing station 12, the pre-assembly mechanism can maintain the positioning of the product and will not loosen the product. When it reaches the nailing station, the connecting cylinder two 84 pushes the push plate 85 forward, and pushes the manual control valve assembly 36 forward to supply air to the pressing component, so that it is kept pressed on the product and the product will not shift during nailing. When it reaches the stacking station, the manual control valve assembly 36 is pushed forward to supply air to the pressing component, so that the pressing component can loosen the product and facilitate unloading.

[0070] Example 2 Based on the structure of Example 1, such as Figure 1 , Figure 12-15As shown, the palletizing mechanism 2 includes at least one palletizing robot 21. The output end of the palletizing robot 21 is provided with a palletizing clamp 22, and each palletizing robot 21 has multiple stacking pallets arranged around it on its outer side. In this embodiment, there are two palletizing robots 21, located on both sides of the palletizing conveyor line.

[0071] like Figure 13-15 As shown, the palletizing fixture 22 includes a drive motor 221, a connecting seat 2221, a mounting base 223, and a clamping assembly 224. The connecting seat 2221 has a connecting flange 225 on one side for connection with the palletizing machine 21, and the drive motor 221 on the other side. A connecting plate 2222 is provided at the output end of the drive motor 221. The mounting base 223 is connected to the connecting plate 2222 via multiple connecting rods 2223. The clamping assembly 224 is mounted on the mounting base 223 and includes a clamping frame 2241, a clamping frame 2242, and a drive mechanism that moves the clamping frame 2241 and the clamping frame 2242 in opposite directions. The second moving component, clamping frame 1 2241 and clamping frame 2242, are frame structures with a stable structure. Clamping frame 1 2241 has a clamping seat 1 2243 on each side of the end away from the mounting base 223. The clamping surface of clamping seat 1 2243 is provided with an elastic clamping plate 2245. Clamping frame 2242 has a clamping seat 2 2244 on each side of the end away from the mounting base 223. The clamping surface of clamping seat 2 2244 is also provided with an elastic clamping plate 2245. The clamping plates of clamping seat 1 2243 and clamping plates 2245 of clamping seat 2244 are arranged opposite to each other and cooperate to clamp the outer side of the product.

[0072] Transmission assembly two includes a drive motor 2246, a gear 2247, a rack 2248, and a rack 2249. The drive motor 2246 is located in the middle of the mounting base 223, and its output end is equipped with the gear 2247. The drive motor 2246 can drive the gear 2247 to rotate. The racks 2248 and 2249 are arranged opposite each other on both sides of the gear 2247 and mesh with the gear 2247. The rotation of the gear 2247 can drive the racks 2248 and 2249 to move towards each other. The clamping frame 2241 is fixedly connected to the rack 2248, and at least one slide rail 22410 parallel to the rack 2248 is provided above the clamping frame 2241. The clamping frame 2242 is fixedly connected to the rack 2249, and at least one slide rail 22411 parallel to the rack 2249 is provided above the clamping frame 2242. The bottom of the mounting base 223 is provided with a slider that is slidably connected to the slide rail 22410 and the slide rail 22411.

[0073] When a product needs to be clamped, gear 2247 rotates, driving racks 2248 and 2249 to move towards each other. This brings clamping frames 2241 and 2242 closer together, with the four clamping plates 2245 clamping the product's outer side, ensuring stable clamping. The gear and rack system has a large travel range, accommodating larger products. Furthermore, the internal programming of the drive motor's five parameters allows for adjustment of the clamping distance within different ranges, enabling the stacking and handling of products of varying sizes. This provides high flexibility and a wide range of applications.

[0074] In this embodiment, the drive motor 221 includes a servo motor and a harmonic reducer. The harmonic gear reducer has the advantages of high load capacity, high transmission efficiency, and smooth movement. It is also small in size and light in weight. It can meet the high load capacity of the fixture and the high-precision steering and positioning capability. It can also rotate 360° to allow the target fixture to reach any angle position and stay there to meet the posture conversion requirements under different working conditions.

[0075] The drive motor 5246 includes a servo motor and a planetary reducer. Through the transmission of gears, racks and pinions and linear guides, it can achieve high transmission efficiency and high load-bearing capacity, high operational stability, and transmission accuracy of up to 0.1mm, thus realizing precise and effective clamping.

[0076] like Figure 15 As shown, there are two slide rails 22410, located on both sides of rack 2248, and two slide rails 22411, located on both sides of rack 2249. The two slide rails 22410 and the two slide rails 22411 are staggered to make the relative movement of clamping frame 2241 and clamping frame 2242 more stable.

[0077] like Figure 13-15 As shown, the palletizing mechanism 6 also includes an auxiliary clamping assembly 226. The auxiliary clamping assembly 226 includes at least one set of auxiliary clamping groups. Each set of auxiliary clamping groups includes two auxiliary clamping members arranged along the diagonal of clamping frame one 2241 and clamping frame two 2242. The two auxiliary clamping members cooperate with a clamping seat one 2243 and a clamping seat two 2244 respectively to assist in clamping the inner side of the product.

[0078] The auxiliary clamping components include a clamping cylinder 2261 and an auxiliary clamping seat 2262. The clamping cylinder 2261 is mounted on either clamping frame one 2241 or clamping frame two 2242. The output end of the clamping cylinder 2261 is provided with the auxiliary clamping seat 2262. A flexible clamping plate 2263 is provided on the side of the auxiliary clamping seat 2262 away from the clamping cylinder 2261. The clamping plate 2263 is positioned opposite to the upper end of the clamping plate 2245 of clamping frame one 2243 or clamping frame two 2244, and cooperates with the clamping plate 2245 of clamping frame one 2243 or clamping plate two 2245 to clamp the inner side of the product. When the product has a certain height, the clamping plate 2245 clamps the outer side of the product, and the clamping plate 2263 clamps the inner side of the product. The cooperation of both improves clamping stability, thereby enhancing the safety of the clamping and transportation process.

[0079] like Figure 16-18 As shown, the mold 3 includes a base frame 31 and a pre-assembly mechanism disposed on the base frame 31. The pre-assembly mechanism is used to pre-assemble products. Depending on the product size, one or more products can be pre-assembled simultaneously. It includes a limiting component 32 and a pressing component 33. The limiting component 32 includes multiple limiting baffles 321 and multiple limiting baffles 322. The multiple limiting baffles 321 are arranged along two sides of the product in the first direction (the conveying direction of the conveying mechanism 1) and can limit the position of the product in the second direction. The multiple limiting baffles 322 are arranged in pairs on the sides of the product in the first direction. At the two corners of side one, two pairs of limiting baffles 322 are vertically set to form a right-angle limiting part. The limiting baffles 321 and 322 work together to limit the displacement of the product in the XZ direction. During installation, with side one of the product as the reference, the limiting baffles 321 and 322 located in the direction of side one are installed. The product is pushed against the limited space formed by the installed limiting baffles 321 and 322. Then the limiting baffle 1 of side two in the first direction is installed to achieve the initial positioning of the mold.

[0080] The pressing component 33 is arranged around the product to press down and fix the product. It works with the limiting component 32 to achieve complete positioning of the product, thereby realizing the pre-assembly of the product and facilitating subsequent nailing.

[0081] like Figure 16 , Figure 18As shown, the base frame 31 is assembled from aluminum alloy beams. A first limiting baffle 321 is fixedly connected to the base frame 31 via nuts located in long slots on the aluminum alloy beams. The pressing component 33 and the second limiting baffle 322 are mounted on a mounting base plate 34, which is also fixedly connected to the base frame 31 via nuts located in long slots on the aluminum alloy beams. One side of the mounting base plate has multiple C-shaped openings that can accommodate the first limiting baffle 321 located on the side. The long slots allow for flexible adjustment of the positions of the first limiting baffle 321, the second limiting baffle 322, and the pressing component 33, thus adapting to the assembly of products of different sizes, offering good flexibility and strong compatibility.

[0082] like Figure 16-18 As shown, the pressing assembly 33 includes a first rotating pressing plate 331 and a second rotating pressing plate 332. Two first rotating pressing plates 331 are provided, positioned opposite each other at both ends in the first direction of the product. The first rotating pressing plate 331 is connected to a first rotating cylinder 333 provided on the mounting base plate 34, and can be pressed above the product by the first rotating cylinder 333. At least one second rotating pressing plate 332 is provided, positioned along the side of the product, between the two first rotating pressing plates 331. The second rotating pressing plate 332 is connected to a second rotating cylinder 334 provided on the mounting base plate 34, and can be pressed above the product by the second rotating cylinder 334. When the first rotating pressing plate 331 and the second rotating pressing plate 332 press down on the product, they limit the product's position in the Y direction.

[0083] Specifically, the pressing part of the rotating lower pressure plate 331 is provided with a limiting groove 3311 that is adapted to the part to be installed on the product. The limiting groove 3311 is provided with outer limiting parts 3312 on both sides. The bottom of the limiting groove 3311 is provided with a Z-shaped limiting plate 335. The limiting plate 335 is provided with spring pins 336 on both sides that are opposite to the two outer limiting parts 3312. When the rotating lower pressure plate is pressed down, the spring pins 336 abut against the inner side of the part to be installed, and the two outer limiting parts 3312 limit the outer side of the part to be installed. The two work together to completely limit the position of the part to be installed on the product, preventing the part to be installed (which is also the main nailing position) from shifting before nailing.

[0084] Correspondingly, the pressing part of the rotating lower pressure plate 332 is provided with a limiting groove 3321 that is adapted to the part to be installed on the product. The limiting groove 3321 is provided with outer limiting parts 3322 on both sides. The bottom of the limiting groove 3321 is provided with at least one limiting plate 335. The limiting plate 335 is provided with spring pins 336 on both sides that are opposite to the two outer limiting parts 3322. Similarly, the spring pins 336 cooperate with the outer limiting parts 3322 to completely limit the position of the part to be installed on the product.

[0085] like Figure 16 , Figure 18As shown, when multiple products are pre-assembled on a mold 3, the limiting component 32 also includes multiple partition plates 323 disposed on the bottom frame 31. The partition plates 323 are arranged in pairs between adjacent products. The two partition plates 323 are arranged opposite each other on both sides of the product in the first direction. The partition plate 323 is T-shaped and includes a side baffle and an isolation part. The isolation part is disposed in the middle of the partition plate and inserted between adjacent products to separate adjacent products. The side baffle extends along both ends of the isolation part and forms two right-angle limiting parts with the isolation part, thereby cooperating with the limiting baffle 1 321 and the limiting baffle 2 322 to simultaneously limit the position of multiple products in the XZ direction.

[0086] Furthermore, a rotating pressure plate 332 is provided between every two adjacent products, and two limiting plates 335 are provided at the bottom of the limiting groove 3321. When the rotating pressure plate 332 is pressed down, the two limiting plates 335 are respectively pressed on the top of one product, and the rotating pressure plate 332 is simultaneously pressed on the top of two adjacent products. The structure is simple and the positioning is stable.

[0087] The working method of this invention is as follows: S1. At the pre-assembly station, one or more products are pre-assembled onto the mold by manual labor to achieve product pre-assembly. Then, the start button of the pre-assembly station is activated, the blocking parts of the pre-assembly conveyor line are released, and the conveyor mechanism transports the mold to each nailing station. S2. The nailing assembly module automatically nails the product according to the product model and automatically fills the nails during the nailing process. S3. After the nailing is completed, the mold is transported to the palletizing station by the conveyor mechanism, and the palletizing mechanism automatically classifies and pallets the products according to their models. S4. After the blanking process, the empty mold is conveyed to the pre-assembly station through the lower conveyor line of the conveying mechanism, waiting for the pre-assembly of the next product. This cycle is repeated to realize the continuous and automatic nailing assembly of products.

[0088] The automatic nailing assembly production line of the present invention also has a Kanban system. Through the dedicated Kanban system, production data can be collected and summarized, and through data analysis, production operations can be guided.

[0089] The automatic nailing and assembly production line of the present invention produces wooden frames for furniture sofas, but it can also be used for nailing and assembling wooden products in the fields of decoration projects, furniture installation, and home furnishing manufacturing.

[0090] The nailing assembly module of this invention can automatically load, nail, and stack products, realizing continuous automatic assembly operations. It eliminates the dependence on professional carpenters, avoids the risks of manual operation, and reduces costs. Moreover, through automatic loading and nailing by the nailing assembly module, nailing can be done from multiple directions, resulting in an aesthetically pleasing product appearance and stable nailing quality, which greatly improves production quality and efficiency.

[0091] Furthermore, this invention is compatible with the nailing assembly of various products. By simply changing the control program and mold, it can quickly adapt to different production tasks, demonstrating good flexibility and compatibility.

[0092] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
