Description

[0002] In the furniture manufacturing industry, cabinet wooden frames usually use mortise and tenon structures to connect multiple wooden strips into shape. To ensure the bonding strength of the mortise and tenon joints, the mortise and tenon parts of the wooden strips need to be coated with glue before assembly. Specifically, glue is evenly applied to the mortise and tenon heads and the corresponding mortise and tenon grooves, and the mortise and tenon heads are then inserted into the mortise and tenon grooves for assembly. Finally, nails are fastened at the mortise and tenon joints to enhance the firmness of the wooden frame connections.

[0003] In existing technology, each process relies on manual labor, including gluing, aligning joints, and nailing. This is not only labor-intensive and time-consuming, but also results in low overall assembly efficiency.

DETAILED DESCRIPTION

[0020] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] like Figure 1-13 The illustrated automatic wood frame production line is used to automate the production of a cabinet wood frame 9. The wood frame 9 comprises a first workpiece 91 and a second workpiece 92 having a mortise and tenon joint 93. The mortise and tenon joint 93 can be a tenon, a mortise and tenon joint, or other structures that can achieve mortise and tenon fit, to meet the requirements for plug-in assembly between the components of the wood frame 9.

[0024] The automatic production line mainly includes a loading module, a gluing module, an assembly module 4, and a nailing module. The loading module includes a first loading mechanism 1 and a second loading mechanism, respectively used to transport the first workpiece 91 and the second workpiece 92 to the corresponding workstations; the gluing module includes a first gluing mechanism 2 and a second gluing mechanism 5, respectively used to apply glue to the mortise and tenon joints 93 of the first workpiece 91 and the second workpiece 92; the assembly module 4 includes a transfer mechanism, a pressing mechanism, and a first mechanical claw 36 for positioning the workpieces after gluing and performing the mortise and tenon joint assembly operation; and the nailing module is used to nail the wooden frame 9, which has completed the mortise and tenon joints, at its connection points.

[0025] In the actual operation process, the first loading mechanism 1 transports the first workpiece 91 to the first gluing mechanism 2, where the gluing process is completed on the tenon and mortise joints 93. The second loading mechanism transports the second workpiece 92 to the assembly module 4, where the second gluing mechanism 5 applies glue to the tenon and mortise joints 93 of the second workpiece 92. Subsequently, the transfer mechanism accurately transfers the glued first workpiece 91 to the assembly module 4, where the pressing mechanism cooperates with the second workpiece 92 to complete the tenon and mortise joint connection. The assembled wooden frame 9 is then transferred to the nailing module by the first mechanical gripper 36, where the tenon and mortise joints are nailed to enhance the connection strength.

[0026] Through the above-mentioned structural design and process coordination, the automatic wooden frame production line of the present invention can realize the full process automation of the cabinet wooden frame 9 from loading, gluing, assembly to nailing, which significantly improves production efficiency and reduces manual participation. It overcomes the problems of poor assembly accuracy, insufficient consistency and high labor intensity brought about by manual operation in the existing technology, and meets the needs of modern furniture manufacturing for efficient, automated and standardized production.

[0027] See Figure 2-4 In this embodiment, the first loading mechanism 1 includes a conveying component and a workpiece transition component.

[0028] Among them, the conveying assembly includes a material storage trough 12 for placing the first workpiece 91, a first driving member 11 and a first conveyor belt 17; the workpiece transition assembly includes a material tapping member 1511, a second driving member 151 connected to the material tapping member 1511, and a material guide member 13, and the material guide member 13 is provided with a material guide slope 131 for guiding the workpiece to slide.

[0029] During the specific working process, the first driving member 11 drives the first workpiece 91 in the material storage trough 12 to enter the first gluing mechanism 2 to complete the gluing treatment of the mortise and tenon part 93; then, the second driving member 151 drives the material shifting member 1511 to move, and shifts the first workpiece 91 to the top of the material guide member 13, and makes it fall on the material guide slope 131, so that under the guidance of the material guide slope 131, the first workpiece 91 slides to the first conveyor belt 17, realizing the smooth transition and automatic transportation of the first workpiece 91.

[0030] Furthermore, to ensure the stability and accuracy of the workpiece feeding process, the workpiece transition assembly also includes a tenth driving member 15 and an eleventh driving member 152, the second driving member 151 is installed on the driving end of the tenth driving member 15, and the driving end of the eleventh driving member 152 is provided with a stop block 1521.

[0031] During operation, after the first workpiece 91 is glued, the tenth driving member 15 drives the second driving member 151 to extend, pushing the material-dispensing member 1511 down to a position close to the first workpiece 91. At the same time, the eleventh driving member 152 drives the material-blocking block 1521 to descend, so that the material-blocking block 1521 and the material-dispensing member 1511 respectively abut against the two sides of the first workpiece 91, thereby limiting the position of the first workpiece 91. Subsequently, the eleventh driving member 152 drives the material-blocking block 1521 to rise, and at the same time, the tenth driving member 15 retracts the second driving member 151, so that the material-dispensing member 1511 completes the dispensing operation on the first workpiece 91. Under the dispensing action, the first workpiece 91 leaves its position and naturally slides into the material-guide slope 131 provided by the material-guide member 13, and finally enters the first conveyor belt 17, realizing the automatic transition and connection of the workpieces.

[0032] The above structural design is simple and compact, which can effectively reduce the space occupied by the equipment and reduce manufacturing costs, while improving the system's integration and operating efficiency; the automatic transition solution further simplifies the conveying and connection process of the first workpiece 91 after gluing, facilitates subsequent processing, and is beneficial to the maintenance and stable operation of the equipment.

[0033] See Figure 5-6 In this embodiment, the first gluing mechanism 2 is used to precisely apply glue to the tenon-and-mortise joints 93 at both ends of the first workpiece 91. It includes a first drive motor 21, a third drive member 24, a first glue gun 222, and a second drive motor 22 and a third drive motor 23 connected to the first glue gun 222. The second drive motor 22 is connected to the first glue gun 222 via a first screw drive member 221, driving the first glue gun 222 in the vertical direction. The third drive motor 23 is connected to the first glue gun 222 via a second screw drive member 231, enabling the first glue gun 222 to reciprocate in the horizontal direction. The second drive motor 22 and the third drive motor 23 cooperate to achieve coordinated vertical and horizontal operation of the first glue gun 222, thereby providing full coverage, uniform, and precise glue application to the tenon-and-mortise joints 93 of the first workpiece 91.

[0034] The driving end of the third drive member 24 is equipped with a rotating pressure block 241. Driven by the third drive member 24, this rotating pressure block 241 can move toward the output shaft of the first drive motor 21, thereby pressing the first workpiece 91 into position. Subsequently, the first drive motor 21 drives the first workpiece 91 to rotate axially. At this time, the second drive motor 22 drives the first glue gun 222 to move vertically, and the third drive motor 23 drives the first glue gun 222 to move horizontally. Through multi-axis coordinated control, continuous and efficient glue application is completed on the mortise and tenon joint 93. This structure combines the two-dimensional movement of the first glue gun 222 with rotational movement, effectively improving glue application consistency and glue utilization.

[0035] To accommodate first workpieces 91 of varying lengths or specifications, the first gluing mechanism 2 utilizes two symmetrically arranged groups of mechanisms, one at each end of the first workpiece 91. One group of the first gluing mechanisms 2 is mounted on a slide 14, which is driven by a ninth drive motor 16. The distance between the two groups of gluing mechanisms can be adjusted based on the length of the first workpiece 91, thereby achieving compatibility with first workpieces 91 of varying specifications and enhancing the overall flexibility and adaptability of the device.

[0036] In addition, in order to ensure precise alignment before gluing, the first gluing mechanism 2 also includes a twelfth driving member 141 located at both ends of the first workpiece 91, and a lifting plate 1411 is connected to the driving end thereof. During operation, the twelfth driving member 141 drives the lifting plate 1411 to rise, lifting the first workpiece 91 to a position aligned with the output shaft of the first drive motor 21 and the rotating pressure block 241. Subsequently, the third driving member 24 drives the rotating pressure block 241 to move toward the direction of the first drive motor 21, completing the clamping and positioning of the first workpiece 91. After completing the above-mentioned alignment, the twelfth driving member 141 drives the lifting plate 1411 to descend, and the first drive motor 21 drives the first workpiece 91 to rotate, cooperating with the driving in various directions to complete the comprehensive gluing of the mortise and tenon parts 93 of the first workpiece 91.

[0037] Through the above structure, a fully automated integrated operation process of the first workpiece 91 from alignment, pressing, rotation to three-axis gluing is realized, which not only avoids the problems of uneven gluing and missing gluing in the manual gluing process, but also improves the gluing accuracy and efficiency, ensuring the consistency and reliability of the mortise and tenon connection strength. In addition, the use of a slide and multi-drive collaborative structure effectively reduces the adjustment cost when the equipment specifications are changed, and enhances the adaptability of the system. The entire mechanism has a compact structure, high control accuracy, good modularity, automation and scalability, and is suitable for the actual needs of modern furniture wood frame automated production lines for high efficiency and high consistency operations.

[0038] See Figure 7-8 The assembly module 4 provided in this embodiment is used to realize the automatic positioning and mortise and tenon joint assembly of the first workpiece 91 and the second workpiece 92 after gluing. Its structural design is compact and the positioning accuracy is high, which is suitable for the efficient automatic assembly requirements of wooden frames of various specifications.

[0039] Specifically, the assembly module 4 is provided with a first slide 41, which is provided with a first positioning groove for accommodating the second workpiece 92. The first positioning groove is formed by the gap between the first positioning block 47 and the second positioning block 48 on the first slide 41. It can effectively limit and guide the lateral position of the second workpiece 92, thereby ensuring the assembly accuracy when it is subsequently connected to the first workpiece 91. There are two sets of first slides 41, located on both sides of the workstation and driven by a tenth drive motor 411. The spacing between the two first slides 41 can be adjusted to accommodate wooden frames 9 of different lengths and specifications, thereby improving the versatility and flexibility of the system.

[0040] The second loading mechanism is used to accurately guide the second workpiece 92 into the assembly station, and includes a second conveyor belt 42 and a flip assembly. The flip assembly includes a stopper 431, a fourth drive member 43 connected thereto, a receiving plate 441, and a fifth drive member 44 connected to the receiving plate 441. During operation, after the second conveyor belt 42 transports the second workpiece 92 to its end, the fourth drive member 43 drives the stopper 431 forward, temporarily blocking and positioning the second workpiece 92. Subsequently, the second gluing mechanism 5 accurately applies glue to the mortise and tenon joints 93 of the second workpiece 92. After gluing is completed, the fourth drive member 43 drives the stopper 431 back, and the second workpiece 92 naturally flips over at the end of the second conveyor belt 42 and falls onto the receiving plate 441. The fifth drive member 44 then drives the receiving plate 441 downward, allowing the second workpiece 92 to stably and smoothly fall into the first positioning groove on the first slide 41, completing positioning.

[0041] The above structure realizes the continuous automated transition of the second workpiece 92 from gluing to precise placement, which not only improves the compactness and beat efficiency of the overall process flow, but also effectively reduces human intervention and error interference, and improves the accuracy and stability of the initial positioning of the assembly.

[0042] Furthermore, to achieve precise and uniform gluing of the mortise and tenon joints of the second workpiece 92, the second gluing mechanism 5 includes a fourth drive motor 52, a sixth drive member 53, and a second glue gun 54 mounted on the drive end of the sixth drive member 53. The second gluing mechanism 5 is secured by a mounting bracket 55 disposed transversely on the first slide 41. The mounting bracket 55 is provided with a first rack 51 extending along its length. The output shaft of the fourth drive motor 52 is provided with a first gear 521 meshingly connected to the first rack 51. The fourth drive motor 52 drives the first gear 521 to rotate, thereby driving the sixth drive member 53 to move along the length of the mounting bracket 55, thereby adjusting the position of the second glue gun 54 in this direction and aligning it with the mortise and tenon joints 93 of the second workpiece 92. During the gluing operation, the sixth drive member 53 drives the second glue gun 54 to descend and apply glue to the mortise and tenon joints 93 of the second workpiece 92.

[0043] This gluing mechanism utilizes a "rack and pinion" mechanism for sliding movement, resulting in a simple structure and smooth operation. It can accommodate a variety of second workpiece lengths (92), improving the efficiency of adjusting the gluing position and the system's responsiveness. Furthermore, the sixth longitudinal drive element (53) controls the lifting and lowering motion of the second glue gun (54), achieving precise, point-to-point glue application to the mortise and tenon joint (93). This effectively avoids excessive or misaligned glue application, ensuring the subsequent securement of the mortise and tenon joint and the economical use of glue.

[0044] The structure of this assembly module integrates multiple functions such as automatic positioning, flexible gluing, and workpiece flipping and blanking, which significantly improves assembly accuracy and process rhythm, reduces the frequency of manual intervention, and has good adaptability and modular expandability, suitable for the efficient docking needs of the wooden frame 9 automatic assembly line.

[0045] See Figure 9 The automatic wooden frame production line of the present invention further includes a frame 3, on which a second rack 31 is arranged along its length; the transfer mechanism includes a supporting bracket 32, a rotating bracket 35 rotatably connected to the supporting bracket 32, and a second mechanical claw 351 provided at the bottom of the rotating bracket 35; The supporting bracket 32 ​​is provided with a fifth drive motor 321, and the output shaft of the fifth drive motor 321 is provided with a second gear meshing with the second rack 31; the connection between the supporting bracket 32 ​​and the rotating bracket 35 is provided with a third gear 33, a third rack 34 meshing with the third gear 33, and a seventh drive member 341 connected to the third rack 34; Among them, a second positioning groove 49 is also provided in the assembly module 4. After the second mechanical claw 351 grabs the first workpiece 91 on the first conveyor belt 17, the seventh driving member 341 drives the third rack 34 to move, so that the third gear 33 rotates and drives the rotating bracket 35 to rotate a certain angle; the fifth driving motor 321 drives the second gear to rotate and drives the supporting bracket 32 ​​to move along the length direction of the frame 3 to realize the transfer of the first workpiece 91 to the second positioning groove 49.

[0046] In this embodiment, the first conveyor belt 17 is provided with a first support plate 171, a second support plate 172 and a fourteenth driving member 173. When the first workpiece 91 after being coated with glue is transferred to the first conveyor belt 17 through the material guide slope 131, it is transported by the first conveyor belt 17 and first abuts against the second support plate 172, and is driven by the fourteenth driving member 173 to abut against the first support plate 171 to achieve positioning when the second mechanical claw 351 grasps it, so that the second mechanical claw 351 can accurately grasp the first workpiece 91 and transfer it to the second positioning groove 49 for subsequent mortise and tenon assembly with the second workpiece 92.

[0047] See also Figure 7-8 The pressing mechanism in this embodiment is used to achieve efficient and accurate mortise and tenon connection and pressing positioning of the first workpiece 91 and the second workpiece 92 after gluing is completed, so as to ensure the stability and long-term reliability of the structural combination.

[0048] Specifically, the pressing mechanism includes a sixth drive motor 45 mounted on the first slide 41, the output end of which is connected to a pressing block 452 via a screw drive assembly 451. This screw drive structure enables precise linear movement of the pressing block 452, thereby applying a stable and controllable pressing force to the second workpiece 92.

[0049] During operation, the sixth drive motor 45 drives the pressing block 452 to move, causing the second workpiece 92 on the first slide 41 to move and press against the first workpiece 91 in the second positioning groove 49, thereby forming a chiseled connection between the two at their respective mortise and tenon joints 93. This mechanical pressing method overcomes initial joint instability caused by glue setting time or slight deformation, thereby significantly improving the strength and consistency of the mortise and tenon joint.

[0050] Furthermore, to enhance the fit during the pressing process, the pressing mechanism is equipped with a fifteenth drive member 46, whose drive end is located above the second workpiece 92. During the pressing process, while the sixth drive motor 45 drives the pressing block 452 to apply the mortise and tenon thrust, the drive end of the fifteenth drive member 46 simultaneously moves downward, exerting a certain vertical auxiliary pressing force on the second workpiece 92. This combined action helps overcome the resistance and gap accumulation errors during the mortise and tenon joint process, thereby ensuring a smooth lateral connection between the second workpiece 92 and the first workpiece 91, achieving a high-quality, highly stable structural joint.

[0051] The pressing mechanism adopts the "screw drive + composite pressing" method, and has the characteristics of compact structure, controllable movement, and adjustable pressure. It can not only adapt to the assembly needs of workpieces of different specifications, but also can efficiently cooperate with the automatic gluing and loading system to realize full-process automated assembly, greatly improving production efficiency and assembly yield.

[0052] See Figure 10-12 The nailing module provided in this embodiment includes a first nailing mechanism 6 and a second nailing mechanism 7 for nailing the mortise and tenon connection parts on both sides of the wooden frame 9. Through the coordinated nailing operation on both sides, the structural strength and positioning accuracy of the overall connection of the component can be effectively improved.

[0053] The first nailing mechanism 6 includes a first bracket 62 mounted on a second slide 61, and a first pneumatic nail gun slidably connected to the first bracket 62. Furthermore, the first nailing mechanism 6 is equipped with a first sliding bracket 63 and a seventh drive motor 64 mounted thereon. The output shaft of the seventh drive motor 64 is connected to a fourth gear 641. The first bracket 62 is provided with a fourth rack 621 along its length, which meshes with the fourth gear 641 and is used to drive the first pneumatic nail gun to move horizontally along the side of the wooden frame, thereby achieving precise positioning of multiple nailing positions.

[0054] To achieve vertical movement of the nail gun, an eighth drive member 65 is provided on the first sliding bracket 63. Its drive end is connected to a first fixed bracket 66, on which the first air nail gun is mounted. When the seventh drive motor 64 rotates the fourth gear 641, it drives the first air nail gun along the length of the first bracket 62 and aligns it with the mortise and tenon joint on one side of the wooden frame 9. The eighth drive member 65 then drives the first air nail gun downward, completing the nailing operation. This structure ensures precise positioning during the nailing operation while achieving efficient and stable force application, effectively preventing stray nails or unsuccessful nailing.

[0055] Similarly, the second nailing mechanism 7 includes a third slide 71, a second bracket 72 mounted thereon, and a second pneumatic nail gun slidably connected to the second bracket 72. Its drive structure includes an eighth drive motor 74 mounted on the second sliding bracket 73. The output shaft of the eighth drive motor 74 is connected to a fifth gear 741, which meshes with the fifth rack 721 on the second bracket 72 to achieve horizontal movement of the second pneumatic nail gun. To achieve vertical nailing, the second sliding bracket 73 is also equipped with a ninth drive member 75, whose drive end is connected to the second fixed bracket 76, on which the second pneumatic nail gun is mounted.

[0056] When the eighth drive motor 74 drives the fifth gear 741 to rotate, the second air nail gun can be accurately aimed at the mortise and tenon connection on the other side of the wooden frame 9, and is driven by the ninth drive member 75 to press down and nail, thereby completing the synchronous nailing operation of the connection between the two sides of the wooden frame 9, significantly improving the assembly efficiency and structural reliability.

[0057] To ensure precise positioning of the wooden frame 9 before nailing, both the first nailing mechanism 6 and the second nailing mechanism 7 are equipped with positioning assistance components. Specifically, the first nailing mechanism 6 is equipped with a sixteenth driving member 611 and a first abutment block 613, while the second nailing mechanism 7 is equipped with a second abutment block 711, an eighteenth driving member 712, and a third abutment block 713. Furthermore, the seventeenth driving member 612 cooperates with the first abutment block 613 to push the wooden frame 9 into position before nailing.

[0058] When the sixteenth driving member 611 is actuated, one side of the wooden frame 9 is driven to abut against the second abutment block 711, and then the seventeenth driving member 612 and the eighteenth driving member 712 drive the two ends of the wooden frame 9 to abut against the first abutment block 613 and the third abutment block 713 respectively, so as to achieve the positioning and pressing of the side and end parts, thereby ensuring that the wooden frame 9 does not shift during the nailing process, thereby improving the nailing accuracy and product assembly consistency.

[0059] To accommodate wooden frames 9 of varying sizes, the first nailing mechanism 6 is equipped with an eleventh drive motor 614, and the second nailing mechanism 7 is equipped with a twelfth drive motor 714, which respectively drive the seventeenth drive member 612 and the eighteenth drive member 712 to move toward or away from the first abutment block 613 and the third abutment block 713, respectively, automatically adapting to the nailing of wooden frames 9 of varying sizes. The nailing module is also equipped with a thirteenth drive motor 67, which is used to drive the first nailing mechanism 6 and the second nailing mechanism 7 to move toward or away from each other, further expanding the adaptability range, enabling automated universal nailing operations for products of various specifications, and improving equipment compatibility and flexible manufacturing capabilities.

[0060] In this embodiment, a finished product conveyor belt 8 is also provided for orderly outputting the wooden frames 9 after the nailing process. Furthermore, a third mechanical gripper 37 is provided on the frame 3 to cooperate with the nailing module. The third mechanical gripper 37 is used to accurately grasp the nailed wooden frames 9 from the nailing module and smoothly transfer them to the finished product conveyor belt 8.

[0061] The setting of this structure enables automatic connection between the nailing and conveying processes, which not only effectively avoids the efficiency bottlenecks and risks of misoperation caused by manual intervention, but also improves the degree of automation and operational smoothness of the entire assembly line, helping to improve product output efficiency and quality stability.

[0062] In summary, the automatic wooden frame production line of the present invention can realize full-process automation of the production of the cabinet wooden frame 9 from loading, gluing, assembly to nailing, overcoming the problems of low efficiency and unstable assembly quality caused by high reliance on manual operation in the existing technology.

[0063] The automatic wooden frame production line of the present invention utilizes a first feeding mechanism in conjunction with a first gluing mechanism 2 to precisely apply glue to the tenon and mortise joints 93 of a first workpiece 91. A second feeding mechanism and a second gluing mechanism 5 are provided to simultaneously process the tenon and mortise joints 93 of a second workpiece 92. A transfer mechanism efficiently transports the glued first workpiece 91 to the assembly station, where it is precisely docked and connected to the second workpiece 92 via a pressing mechanism, effectively reducing errors in manual insertion. Subsequently, a first mechanical gripper 36 stably grasps and transfers the assembled wooden frame 9 to the nailing module, enabling automated nailing and further enhancing the structural strength of the tenon and mortise joints.

[0064] The automatic production line for wooden frames of the present invention has various modules that work in coordination, replacing the traditional complicated processes of manual gluing, alignment and splicing, and nailing, thereby greatly reducing labor intensity and manpower dependence. At the same time, due to the use of mechanical control, it can maintain high repeatability and high consistency in assembly quality, ensure the bonding effect of the mortise and tenon joints and the overall connection strength of the wooden frame 9, significantly improve production efficiency and the qualified rate of finished products, and fully meet the actual needs of the modern furniture manufacturing industry for efficient, automated, and standardized production.
