Description

Technical Field

[0001] This utility model relates to the field of cabinet wooden frame equipment, specifically to an automatic wood flipping device. Background Technology

[0002] In the production of cabinet frames, mortise and tenon joints are typically used to connect multiple wooden strips. Before mortise and tenon assembly, glue must be applied to the mortise and tenon joints of the wooden strips used to make the frame. This involves evenly applying glue to the mortise and tenon joints and grooves to achieve a reliable bonding effect. To facilitate glue application, wooden strips with mortise and tenon joints are usually placed horizontally, while wooden strips with mortise and tenon grooves are usually placed vertically to facilitate the injection of glue into the grooves. However, this inconsistent placement means that before subsequent mortise and tenon assembly, the vertically placed wooden strips with mortise and tenon grooves must be flipped to a horizontal position to precisely align with the mortise and tenon joints.

[0003] In existing technologies, the flipping action mostly relies on mechanical grippers or robotic arms. Although this can achieve automated processing, for small automated equipment with compact structures and high cost sensitivity, robotic arm systems are not only expensive, but also complex in structure and difficult to maintain, which is not conducive to their promotion and application in small and medium-sized furniture manufacturing enterprises.

[0018] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] like Figure 1-4 The diagram shows an automatic wood flipping device for assembling a cabinet frame with adhesive. It includes a frame 1 and a flipping mechanism. The frame 1 is equipped with an adhesive application mechanism and a conveying assembly. The adhesive application mechanism is used to apply adhesive to the tenon and mortise joints of the workpiece 12. The flipping mechanism includes a blocking assembly and a receiving assembly. When the conveying assembly transports the workpiece 12 to the end of the conveying assembly, the blocking assembly extends and blocks the movement of the workpiece 12. After the adhesive application mechanism applies adhesive to the tenon and mortise joints of the workpiece 12, the blocking assembly retracts, and the workpiece 12 flips under the conveying action of the conveying assembly and falls onto the receiving assembly.

[0022] Therefore, this utility model's automatic wood flipping device enables the workpiece 12 to automatically flip under the continuous conveying action at the end of the conveying component and fall smoothly into the receiving component. The device has a compact structure and stable operation, effectively reducing equipment costs and control system complexity, and is more suitable for the application needs of small and medium-sized furniture enterprises in achieving automation and standardization in the wood frame production process.

[0023] Furthermore, the frame 1 is equipped with a slide 2, on which a first slide 3 and a second slide 4 are slidably connected; the first slide 3 is equipped with a first fixed bracket 32, and the second slide 4 is equipped with a second fixed bracket 42. The conveying assembly includes a first conveyor belt 33 mounted on the first fixed bracket 32 ​​and a second conveyor belt 43 mounted on the second fixed bracket 42. When the workpiece 12 is placed on the conveying assembly, one end of it is located on the first conveyor belt 33, and the other end is located on the second conveyor belt 43. The first conveyor belt 33 and the second conveyor belt 43 operate synchronously to convey the workpiece 12. By separating the first conveyor belt 33 and the second conveyor belt 43, the distance between them can be adjusted to accommodate workpieces 12 of different lengths, meeting the needs of multi-specification production.

[0024] Specifically, the material blocking assembly includes a first drive member 35 disposed on the first slide table 3 and located at the end of the first conveyor belt 33, and a second drive member 45 disposed on the second slide table 4 and located at the end of the second conveyor belt 43. The first drive member 35 is provided with a first material blocking member 351 on its drive end, and the second drive member 45 is provided with a second material blocking member 451 on its drive end. When the workpiece 12 is conveyed to the end via the first conveyor belt 33 and the second conveyor belt 43, the first drive member 35 drives the first stop member 351 to extend, and the second drive member 45 drives the second stop member 451 to extend synchronously, and together they abut against the workpiece 12 to restrict its continued movement, so that the glue application mechanism can perform stable and efficient glue application on the tenon and mortise parts of the workpiece 12.

[0025] Furthermore, the receiving assembly includes a third driving member 36 disposed on the first slide 3 and a fourth driving member 46 disposed on the second slide 4. The driving end of the third driving member 36 is provided with a first receiving plate 361, and the driving end of the fourth driving member 46 is provided with a second receiving plate 461. After the first drive component 35 drives the first stop component 351 to retract and the second drive component 45 drives the second stop component 451 to retract, the third drive component 36 drives the first receiving plate 361 to rise and the fourth drive component 46 drives the second receiving plate 461 to rise. This is used to receive the workpiece 12 that is flipped and falls under the push of the conveyor. This not only ensures that the workpiece falls smoothly into the receiving position, but also ensures that its flipping angle is accurate, providing a good positioning basis for subsequent tenon and mortise assembly.

[0026] Furthermore, the first slide 3 is provided with a first positioning block 37, and the second slide 4 is provided with a second positioning block 47, and the gap between the first positioning block 37 and the second positioning block 47 forms a positioning groove. When the workpiece 12 flips over and falls above the first receiving plate 361 and the second receiving plate 461, the third driving component 36 drives the first receiving plate 361 to descend, and the fourth driving component 46 drives the second receiving plate 461 to descend synchronously, so that the workpiece 12 falls accurately into the positioning groove, completing the precise positioning after flipping, which facilitates the smooth progress of subsequent operations.

[0028] It should be noted that the sliding bracket 6 is also equipped with an eighth driving component 7, and the glue gun 71 is installed on the driving end of the eighth driving component 7. When the first driving motor 62 drives the gear 621 to rotate, it can drive the sliding bracket 6 to move along the length direction of the mounting bracket 5, thereby synchronously driving the eighth driving component 7 and the glue gun 71 it carries to move; when the glue gun 71 moves to the tenon and mortise part aligned with the workpiece 12, the eighth driving component 7 drives the glue gun 71 to descend vertically and apply glue to the tenon and mortise part at a fixed point, realizing automatic control and precise execution of the glue application operation.

The first slide 3 is connected to the second drive motor 22 through the first lead screw transmission assembly 24, and the second slide 4 is connected to the second drive motor 22 through the second lead screw transmission assembly 25. When the second drive motor 22 simultaneously drives the first lead screw transmission assembly 24 and the second lead screw transmission assembly 25 to rotate, it can drive the first slide 3 and the second slide 4 to move closer to or further away from each other.

[0030] Specifically, the slide block 2 is equipped with a third guide rail 23, the bottom of the first slide block 3 is equipped with a third slider 31 that slides in cooperation with the third guide rail 23, and the bottom of the second slide block 4 is equipped with a fourth slider 41 that slides in cooperation with the third guide rail 23. Through the cooperation of the third guide rail 23 with the third slider 31 and the fourth slider 41, a smooth sliding connection between the first slide block 3 and the second slide block 4 on the slide block 2 is achieved. By simultaneously driving two lead screw transmission components with the second drive motor 22, the first slide block 3 and the second slide block 4 move horizontally, thereby adaptively adjusting according to the length of the workpiece 12 to meet the automated operation requirements of workpieces 12 of different specifications, improving the adaptability and production efficiency of the equipment.

[0031] Furthermore, it also includes a pressing mechanism for mortise and tenon assembly of workpiece 12, the pressing mechanism including a first pressing component disposed on the first slide 3 and a second pressing component disposed on the second slide 4.

[0032] The first pressing assembly includes a third drive motor 34 and a first pressing block 342, the first pressing block 342 being connected to the third drive motor 34 via a third lead screw transmission assembly 341; the second pressing assembly includes a fourth drive motor 44 and a second pressing block 442, the second pressing block 442 being connected to the fourth drive motor 44 via a fourth lead screw transmission assembly 441.

[0033] During operation, when the third drive motor 34 drives the third lead screw transmission assembly 341 to rotate, and the fourth drive motor 44 drives the fourth lead screw transmission assembly 441 to rotate, the first top pressure block 342 and the second top pressure block 442 can be moved toward the workpiece 12 respectively, and top pressure is applied to it to achieve precise docking and assembly of the tenon and mortise.

[0034] Specifically, to prevent the workpiece 12 from warping or misaligning the tenon and mortise due to uneven force during the pressing process, the first slide 3 is provided with a fifth driving member 38 for pressing the top of the workpiece 12, and the second slide 4 is provided with a corresponding sixth driving member 49; in addition, the second slide 4 is also provided with a seventh driving member 48 to further assist in effectively pressing the workpiece 12 and ensure the assembly accuracy and stability of the tenon and mortise structure.

[0035] In this embodiment, the first slide 3 is also provided with a first positioning groove 8 for preventing another workpiece, and the second slide 4 is also provided with a second positioning groove 9 for preventing another workpiece. The workpiece 12, after being coated with glue and flipped, can accurately fall into the above positioning groove to achieve precise tenon and mortise assembly with another workpiece.
