Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, specifically to a high-precision seamless splicing device for solid wood furniture processing. Background Technology

[0002] Furniture refers to a broad category of appliances and facilities that are essential for human beings to maintain normal life, engage in production practices, and carry out social activities. Furniture has also continuously developed and innovated with the times, and now it has many categories, different materials, complete varieties, and different uses. In the furniture production process, wood splicing devices are needed to splice the wood boards.

[0003] For example, Chinese patent (CN221391458U) discloses a high-precision seamless splicing device for bamboo furniture processing. This high-precision seamless splicing device for bamboo furniture processing improves upon the existing technology, which still suffers from the inability to perform large-scale splicing operations and low work efficiency in actual use. This solution can glue and fix or assemble multiple wooden boards at once, which can effectively improve the work efficiency of the equipment. After the wooden boards are clamped, the main supports on the left and right sides move to the middle position, thereby aligning the bamboo boards. After applying glue, they can be glued together.

[0004] In existing technologies, when two wooden boards are joined together, they need to be manually aligned. Otherwise, misalignment will occur during the joining process. Misalignment will lead to unevenness or instability at the joint, thus affecting the structural stability and appearance quality of the entire product. If the joint is not tight or is crooked, it may affect the performance or require rework and repair. The need for manual adjustment and repair of misaligned boards will disrupt the rhythm of the production line, prolong production time, and affect production efficiency. To address the above problems, a high-precision seamless splicing device for solid wood furniture processing is proposed to solve the problem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-precision seamless splicing device for solid wood processing. It solves the problem that in the existing technology, when two wooden boards are joined, manual alignment of the two boards is required. Otherwise, misalignment of the boards will occur during the joining process. Misalignment of the boards will lead to unevenness or instability at the joint, thereby affecting the structural stability and appearance quality of the entire product. If the joint is not tight or is crooked, it may affect the use effect or require rework and repair. The need for manual adjustment and repair of misaligned boards will disrupt the rhythm of the production line, prolong production time, and affect production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-precision seamless splicing device for solid wood processing, comprising a base plate, wherein first moving guide rails are fixedly connected to the front and rear sides of the upper surface of the base plate, and mounting frames are slidably connected to the left and right sides above the two sets of first moving guide rails via sliding blocks, wherein at least seven sets of rollers are rotatably connected inside the two sets of mounting frames via rotating shafts, fixing seats are fixedly connected to the left and right sides of the upper surface of the base plate, and baffles are fixedly connected to the side of the two sets of mounting frames near the fixing seats, and centering components are installed in the middle of the upper part of the two sets of mounting frames.

[0007] Preferably, a push cylinder is fixedly installed on the side of each of the two sets of fixed seats, and the output end of each of the two sets of push cylinders passes through the side of the fixed seat and is fixedly connected to the side of the baffle through a connector.

[0008] Preferably, the centering component includes two sets of support frames, the bottom of which are fixedly connected to the top of the mounting frame by welding, and a fixing plate is fixedly connected between the two sets of support frames.

[0009] Preferably, a servo motor is fixedly installed in the middle of the upper surface of the fixed plate. The output end of the servo motor passes through the bottom surface of the fixed plate and is fixedly connected to a transmission rod. Both ends of the transmission rod are rotatably connected to a connecting rod via a rotating shaft.

[0010] Preferably, the bottom of both sets of support frames is fixedly connected to a second movable guide rail, and the left and right ends of the two sets of second movable guide rails are slidably connected to mounting strips via sliding blocks, and the bottom of each mounting strip is fixedly connected to at least five centering rods.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device 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.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Reference Figure 1 - Figure 4 As shown, a high-precision seamless splicing device for solid wood processing includes a base plate 1. First moving guide rails 2 are fixedly connected to both the front and rear sides of the upper surface of the base plate 1. Mounting frames 3 are slidably connected to the left and right sides above the two sets of first moving guide rails 2 via sliding blocks. The double-guide rail design makes the mounting frames 3 slide more smoothly. Combined with high-precision sliding blocks, millimeter-level displacement control is achieved, ensuring seamless splicing edges. At least seven sets of rollers 7 are rotatably connected inside the two sets of mounting frames 3 via rotating shafts. Fixed seats 5 are fixedly connected to the left and right sides of the upper surface of the base plate 1. Baffles 4 are fixedly connected to the side of each mounting frame 3 closest to the fixed seats 5. A centering component 8 is installed in the middle of the upper part of each set of mounting frames 3. The baffles 4 serve as the initial positioning reference for the wooden boards, ensuring that one end of each wooden board is aligned, reducing manual calibration time. They are linked with a pushing cylinder 6 to achieve automated propulsion.

[0023] Specifically, each of the two sets of fixed seats 5 has a push cylinder 6 fixedly installed on its side. The output ends of the two sets of push cylinders 6 pass through the side of the fixed seat 5 and are fixedly connected to the side of the baffle 4 through the connector. The fixed seat 5 stably supports the push cylinder 6 to prevent the push force from shifting. They are symmetrically distributed on both sides of the base plate 1 to balance the force and prevent the device from deforming. The push cylinder 6 provides controllable thrust and achieves uniform speed advancement through program control to avoid misalignment or deformation of the wooden board due to uneven force.

[0024] Specifically, the centering component 8 includes two sets of support frames 801. The bottom of both sets of support frames 801 is fixedly connected to the top of the mounting frame 3 by welding. A fixing plate 802 is fixedly connected between the two sets of support frames 801. The support frames 801 provide rigid support for the fixing plate 802 to ensure the stability of the centering operation.

[0025] Specifically, a servo motor 806 is fixedly installed in the middle of the upper surface of the fixed plate 802. The output end of the servo motor 806 passes through the bottom surface of the fixed plate 802 and is fixedly connected to a transmission rod 807. Both ends of the transmission rod 807 are rotatably connected to a connecting rod 808 through a rotating shaft. The servo motor 806 has a built-in torque sensor, which can automatically stop when the clamping force reaches the set value.

[0026] Specifically, the bottom of each of the two sets of support frames 801 is fixedly connected to a second moving guide rail 809. The left and right ends of the two sets of second moving guide rails 809 are slidably connected to mounting strips 810 via sliding blocks. The bottom of each mounting strip 810 is fixedly connected to at least five centering rods 811. Through a mechanical linkage structure, the rotational motion is converted into the synchronous lateral movement of the mounting strips 810, ensuring that the centering rods 811 on both sides approach each other at the same speed, achieving high-precision centering. The centering rods 811 are densely arranged to cover the edge of the wooden board, applying force evenly to avoid local stress concentration and prevent deformation of the wooden board.

[0027] Specifically, the ends of the two connecting rods 808 away from the transmission rod 807 are rotatably connected to the middle of the upper surface of the two mounting strips 810 via a rotating shaft.

[0028] Specifically, on the upper surface of the fixed plate 802, clamping cylinders 803 are fixedly installed on both the left and right sides of the servo motor 806. The output ends of the two sets of clamping cylinders 803 are fixedly connected to push rods 804, and the ends of the two push rods 804 are fixedly connected to clamping plates 805. The dual-cylinder symmetrical clamping design balances the downward pressure, prevents the wood board from warping or sliding during the splicing process, and improves the reliability of glue bonding. The clamping plate 805 is made of flexible material to avoid causing indentations on the surface of the wood board.

[0029] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The specific embodiments disclosed herein omit detailed descriptions of known functions and components. To ensure compatibility of the equipment, the operating methods used are consistent with the parameters of commercially available instruments. In addition, the power source of the cylinder is provided by an external air source component. The specific air pump, pipeline and control system are not within the protection scope of this utility model, so they will not be described in detail.

[0030] Working Principle: The two wooden boards to be spliced ​​are placed on the rollers 7 of the left and right sets of mounting frames 3, respectively. The rollers 7 can rotate freely via a rotating shaft, facilitating the sliding of the wooden boards on the mounting frames 3. After the wooden boards are placed, their positions are initially adjusted so that one end of the wooden board abuts against the baffle 4, preparing for the centering and splicing stage. The servo motor 806 of the centering component 8 is started, and its output end drives the transmission rod 807 to rotate. The connecting rods 808 at both ends of the transmission rod 807 rotate accordingly. The end of the connecting rod 808 away from the transmission rod 807 is connected to the mounting strip 810. Under the push of the connecting rod 808, the two sets of mounting strips 810 slide synchronously towards the center along the second moving guide rail 809. The centering rod 811 at the bottom of the mounting strip 810 moves accordingly and contacts the sides of the wooden board. As the mounting strip 810 moves, it pushes the two wooden boards to the center position, achieving lateral centering and ensuring precise splicing edges. Correspondingly, after alignment, the clamping cylinder 803 on the fixing plate 802 is activated. Its output end pushes the push rod 804 downward, causing the clamping plate 805 to descend and press against the upper surface of the wooden board. The clamping plate 805 applies stable pressure to the wooden board to prevent the wooden board from shifting up and down or left and right during the splicing process, ensuring the stability of the joint. Then, glue is applied to the joint surface of the wooden board. The push cylinder 6 on the fixing seat 5 is activated. Its output end passes through the fixing seat 5 and pushes the baffle 4. The baffle 4 drives the mounting frame 3 to slide towards the center along the first moving guide rail 2. The left and right sets of mounting frames 3 move towards the center synchronously. The two wooden boards placed on the roller 7 then move closer together until the joint edges are completely fitted, completing the seamless splicing. After the splicing is completed, the clamping cylinder 803 drives the clamping plate 805 to rise and reset. The push cylinder 6 drives the mounting frame 3 back to the initial position. The spliced ​​wooden board is then removed, and the next round of work can begin.
