Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing equipment technology, and in particular to a furniture board assembly and shaping device. Background Technology

[0002] In the furniture manufacturing industry, panel assembly and shaping is a crucial step in the production process, especially for mass production of panel furniture (such as wardrobes, bookcases, and cabinets). Traditional assembly methods rely heavily on manual positioning and fixing. Operators must manually align the panels and secure them using clamps or temporary support structures, then complete the assembly using screws or gluing. This method suffers from low efficiency, high labor intensity, and poor precision consistency. In particular, during large-scale production, human factors can easily lead to structural deviations in the finished product, affecting the quality and stability of the furniture.

[0003] To address the aforementioned issues, some semi-automatic or fully automatic assembly equipment has emerged in the existing technology. For example, pneumatically or hydraulically driven pressing devices use fixed positioning blocks to initially limit the position of the boards, and then apply pressure through a pressing head to achieve pressing and connection. However, such equipment is mostly designed for cabinets of specific sizes or structures, lacking flexible and adjustable positioning and pressing mechanisms, making it difficult to adapt to the needs of customized production with multiple specifications and small batches. Furthermore, existing equipment often suffers from complex structures, cumbersome adjustments, and large space requirements, limiting its widespread application in small and medium-sized furniture enterprises.

[0004] On the other hand, some improved devices attempt to achieve moving pressing functions through guide rails and motor drives. However, their structural designs often fail to effectively balance flexible adjustment capabilities in both horizontal and vertical directions, or lack precise limiting functions for the cabinet edges. This causes the sheet metal to easily shift or misalign during pressing, affecting assembly accuracy. Especially in situations requiring bidirectional synchronous adjustment, existing devices generally suffer from sluggish response and poor synchronization of the adjustment mechanism, failing to meet the requirements of high-precision assembly. Furthermore, the insufficient versatility and adjustability of the pressing components make it difficult to adapt to the pressing needs of sheet metal of different thicknesses, further limiting the applicability of the equipment. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a furniture board assembly and shaping device that can improve assembly efficiency and adapt to multiple specifications of customization.

[0006] This utility model is implemented using the following method: a furniture board assembly and shaping device, including a support base, with first guide rails provided at both the left and right ends of the upper surface of the support base, and fixing blocks provided at both the front and rear ends of the middle part of the upper surface of the support base. A first motor is provided on the front fixing block, and the output end of the first motor is connected to a first screw. The end of the first screw is connected to the rear fixing block via a bearing. Moving blocks are spirally sleeved at both the front and rear ends of the first screw. A moving seat is provided on the upper surface of the moving block. Sliding blocks for embedding the first guide rails are provided at both the left and right sides and the front and rear ends of the lower surface of the moving seat. A second guide rail is provided at both the left and right ends of the upper surface of the moving seat. A second motor is provided inside the second guide rail, and the output end of the second motor is connected to a second screw. A slider is spirally sleeved on the second screw. An L-shaped moving block is provided on the upper surface of the slider. A telescopic cylinder is provided on the upper surface of the horizontal plate of the upper surface of the L-shaped moving block. An assembly pressing component is provided at the end of the telescopic rod of the telescopic cylinder. A limiting groove that matches the edge of the assembled cabinet is opened on the inner side of the vertical plate of the L-shaped moving block.

[0007] Furthermore, the assembly pressing component includes a lifting plate, the lifting plate is provided at the end of the telescopic rod of the telescopic cylinder, a third screw is spirally embedded at the upper end of the lifting plate, a pressing block is provided at the lower end of the third screw, and the third screw is fixed by a fixing nut.

[0008] Furthermore, the first half of the first screw has a left-hand thread, and the second half of the first screw has a right-hand thread.

[0009] The beneficial effects of this utility model are as follows: This utility model achieves multi-directional precise adjustment through the linkage structure of double guide rails and screws.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please continue reading. Figures 1 to 3As shown, this utility model provides an embodiment: a furniture board assembly and shaping device, including a support base 1. First guide rails 11 are provided at both the left and right ends of the upper surface of the support base 1. Fixing blocks 12 are provided at both the front and rear ends of the middle part of the upper surface of the support base 1. A first motor 13 is provided on the front fixing block 12. The output end of the first motor 13 is connected to a first screw 14. The end of the first screw 14 is connected to the rear fixing block 12 via a bearing. Moving blocks 15 are spirally sleeved at both the front and rear ends of the first screw 14. A moving seat 2 is provided on the upper surface of the moving block 15. Moving seats 2 have moving blocks at both the left and right sides and the front and rear ends of their lower surfaces. A sliding block (not shown) is provided for embedding into the first guide rail 11. A second guide rail 21 is provided at both the left and right ends of the upper surface of the movable seat 2. A second motor (not shown) is provided inside the second guide rail 21. The output end of the second motor is connected to a second screw 22. A slider (not shown) is spirally sleeved on the second screw 22. An L-shaped moving block 23 is provided on the upper surface of the slider. A telescopic cylinder 24 is provided on the upper surface of the horizontal plate of the L-shaped moving block 23. An assembly pressing part 3 is provided at the end of the telescopic rod of the telescopic cylinder 24. A limiting groove 25 that matches the edge of the assembled cabinet is opened on the inner side of the vertical plate of the L-shaped moving block 23.

[0015] The support base refers to the base that supports the overall structure. Specifically, it can be achieved by combining a welded steel plate frame with reinforcing ribs to provide a stable installation foundation.

[0016] The first guide rail refers to the guide structure that extends along the left and right direction of the support base. Specifically, it can be a T-slot guide rail that works in conjunction with a sliding block to constrain the horizontal movement trajectory of the moving seat.

[0017] The first screw refers to the transmission component that achieves bidirectional movement through motor drive. Specifically, it can be a double-headed reverse threaded rod, used to drive the moving blocks to move in opposite directions to adjust the spacing.

[0018] L-shaped moving blocks refer to movable parts with vertical and horizontal extension surfaces. They can be made of aluminum alloy casting and are used to support pressing components and constrain the edge position of the sheet metal.

[0019] A limiting groove is a groove structure that matches the shape of the edge of the sheet material. Specifically, it can be designed as a U-shaped groove or a V-shaped groove to prevent the sheet material from shifting laterally during the pressing process.

[0020] Specifically, the first guide rail on the support base cooperates with the sliding block, allowing the movable seat to move smoothly in the left-right direction. When the first motor drives the first screw to rotate, the movable blocks at both ends move closer or further apart synchronously under the action of the reverse threads, thereby adjusting the spacing of the movable seats to accommodate plates of different widths. The second guide rail on the movable seat cooperates with the second screw, and the pressing assembly moves in the front-back direction driven by the second motor. The L-shaped movable block controls the lifting and lowering of the pressing component through a telescopic cylinder, and the limiting groove on the inner side of its vertical plate engages with the edge of the plate during pressing, ensuring that the plate does not misalign during pressing.

[0021] Compared to existing technologies, traditional equipment relies on fixed positioning blocks, limiting the adjustment range. This solution, however, achieves multi-degree-of-freedom horizontal adjustment through a bidirectional adjustable guide rail and screw system. Existing technologies lack edge-limiting functionality in the pressing components; this solution significantly improves positioning accuracy by interlocking the limiting groove with the edge of the sheet material. Furthermore, the modular guide rail and drive structure simplify the equipment's complexity, making it more suitable for multi-specification production needs.

[0022] Through the above technical solution, this application can quickly adjust the pressing position to adapt to different sized plates, effectively avoiding positioning deviations caused by manual operation. The fit between the limiting groove and the edge of the plate significantly improves pressing stability, while the bidirectional adjustment mechanism simplifies the equipment adjustment process and improves assembly efficiency.

[0023] Please continue reading. Figures 1 to 3 As shown, in one embodiment of the present invention, the assembly pressing component 3 includes a lifting plate 31, the lifting plate 31 is provided at the end of the telescopic rod of the telescopic cylinder 24, a third screw 32 is spirally embedded at the upper end of the lifting plate 31, a pressing block 33 is provided at the lower end of the third screw 32, and the third screw 32 is fixed by a fixing nut 34.

[0024] The lifting plate is a transition component connecting the telescopic cylinder and the pressing block. It can be made of aluminum alloy sheet and is rigidly connected to the end of the telescopic rod of the telescopic cylinder by bolts to transmit vertical pressure.

[0025] The third screw refers to an adjusting rod with external threads, specifically a trapezoidal thread structure. Rotating the screw allows for fine-tuning of the pressing block in the vertical direction. The thread length can be set from 50 to 80 millimeters to meet the requirements of different sheet thicknesses. The pressing block is the force-applying component that directly contacts the sheet material. It can be made by encapsulating a metal substrate with polyurethane material, and the surface can be machined with anti-slip textures to increase friction.

[0026] The fixing nut is a fastener used to lock the position of the third screw. Specifically, it can be a wing nut structure, which can be tightened manually to fix the position of the screw.

[0027] Specifically, the lifting plate achieves vertical movement via a telescopic cylinder. A third screw engages with a threaded hole at the end of the lifting plate; rotating the third screw changes the relative height between the pressing block and the lifting plate. Once the pressing block contacts the sheet material, further rotation of the third screw applies preload, which is then locked in place by a fixing nut. This structure allows for real-time pressure adjustment based on the sheet material thickness during pressing, preventing insufficient pressure or overload due to sheet material tolerances.

[0028] Compared to existing technologies, traditional pressing devices mostly use pressure heads with a fixed height, which cannot adapt to the pressing requirements of plates with different thicknesses. This solution uses an adjustable screw structure to enable the pressing block to have a height compensation function, while using a fixing nut to eliminate positional displacement caused by thread clearance, ensuring the stability of the pressing force.

[0029] Through the above technical solution, this application solves the problem of inaccurate pressure control caused by the difference in plate thickness in traditional pressing devices. It can adapt to the pressing needs of plates with a thickness range of 1-3 cm. During the pressing process, the pressing block and the plate always maintain surface contact, avoiding plate deformation caused by local stress concentration.

[0030] Please continue reading. Figures 1 to 3 As shown, in one embodiment of the present invention, the front half of the first screw 14 is a left-hand thread, and the rear half of the first screw 14 is a right-hand thread.

[0031] Among them, left-hand thread refers to a thread structure that generates forward motion when rotated counterclockwise. It can be achieved by single-start or multi-start thread processing, and the movement direction of the moving block is controlled by changing the direction of the thread.

[0032] Among them, right-hand thread refers to a thread structure that generates forward motion when rotated clockwise. Specifically, it can be achieved by using a machining method symmetrical to that of left-hand thread, and bidirectional synchronous adjustment can be achieved through the combination of double-threaded directions.

[0033] Specifically, the first screw, through a combination of a left-hand thread in the front half and a right-hand thread in the rear half, drives a single motor to cause the moving blocks at both ends to move in opposite directions in a linear motion as the screw rotates. When the first motor rotates forward, the left-hand thread in the front half drives the front moving block to move backward, while the right-hand thread in the rear half drives the rear moving block to move forward, thus achieving synchronous opposite-direction movement of the two moving blocks. When the motor rotates in the reverse direction, the two moving blocks synchronously separate in the opposite direction. This bidirectional motion mechanism achieves symmetrical adjustment through a single drive source, ensuring balanced force on both sides during the plate positioning process.

[0034] Compared to existing technologies, traditional assembly equipment typically uses a single-direction screw, which can only achieve unidirectional displacement of a single moving block. Additional drive devices or mechanical structures are required to achieve bidirectional adjustment. This solution, through an integrated design of dual-direction screws, significantly improves positioning adjustment efficiency while maintaining structural compactness, avoiding positioning deviations caused by asynchronous multiple drive sources.

[0035] Through the above technical solution, this application can realize the symmetrical synchronous adjustment of the board clamping mechanism, eliminate the positioning offset problem caused by unilateral pressure, simplify the equipment drive structure, adapt to the rapid positioning needs of boards of different specifications, and meet the requirements of multi-size compatibility in customized furniture production.

[0036] The telescopic cylinder and motor of this utility model are both existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0037] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
