Description

Technical Field

[0001] This invention relates to the field of furniture manufacturing technology, specifically to an automatic pre-embedding device and process for side panel screws in panel furniture. Background Technology

[0002] In panel furniture production, the side panel is a core load-bearing component, and the installation quality of its embedded parts directly affects the overall structural stability and assembly efficiency. Traditional manual embedding methods have problems such as large positioning deviations, low efficiency, and poor consistency. Therefore, nowadays, the mainstream embedded processing equipment in woodworking workshops mostly relies on conveyor belts to achieve continuous conveying of boards, and then uses vibratory feeders and linear feeders to continuously convey screw embedded parts, thereby carrying out subsequent embedded operations.

[0003] During the conveyor belt transport of boards, when the conveyor belt stops suddenly, the bottom surface of the wooden boards has a low coefficient of friction and is easily affected by the inertia of motion, causing it to slip back and forth or shift slightly. This will seriously affect the accuracy of subsequent pre-embedded work positions. Even if the equipment is equipped with a high-precision laser positioning system, it is impossible to eliminate the displacement deviation of the boards from a physical level: the amount of slippage of the boards each time it stops is not fixed and the deviation is random. This not only greatly increases the computing load of the control system, but also causes frequent standby correction and cycle interruption in the pre-embedded work, which seriously reduces the continuity of production. Moreover, if the deviation exceeds the laser compensation adjustment range, it is necessary to manually push and pull the boards again to correct them and re-align them, which increases the labor intensity of the workers and reduces the corresponding production efficiency.

[0004] Therefore, it is necessary to invent an automatic pre-embedding device and pre-embedding process for side panel screws in panel furniture to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic pre-embedding device and process for side panel screws in panel furniture. By setting an adjustable baffle plate, the device aims to prevent the panel from slipping due to inertia and ensure the stability of the panel during pre-embedding.

[0006] To achieve this objective, the present invention adopts the following technical solution: An automatic pre-embedding device for side panel screws in panel furniture is provided, comprising a frame, a conveyor belt rotatably connected inside the frame, a gantry frame fixedly connected to the top of the frame, an anti-slip component for clamping and positioning the panel on one side of the gantry frame, the anti-slip component including a connecting plate on one side of the gantry frame, a clamping plate below the connecting plate, a rubber roller rotatably connected to one side of the clamping plate, a one-way anti-return mechanism for preventing the rubber roller from rotating in the opposite direction inside the clamping plate, a buffer component for preventing hard collisions of the panel on one side of the connecting plate, and a linkage component for driving the clamping plate to slide and clamp on one side of the buffer component. When the panel is conveyed and comes into contact with the buffer component, the linkage component can drive the clamping plate to slide inward synchronously, clamping and limiting the side wall of the panel.

[0009] As a preferred embodiment of an automatic pre-embedding device for side panel screws in panel furniture, the gantry frame is equipped with a pre-embedding component for automatically picking up materials and pre-embedding screws. The pre-embedding component includes a linear feeder fixedly connected to one end of the gantry frame, one end of which is connected to the feeding end of a vibratory feeder. An electric slide rail is fixedly connected to the inner wall of the gantry frame, and an electric slider is slidably connected to the bottom end of the electric slide rail. A lifting cylinder is fixedly connected to the bottom end of the electric slider, and a fixed cylinder is fixedly connected to the output end of the lifting cylinder. A laser sensor is installed at the bottom end of the fixed cylinder, and a servo motor is fixedly connected to the inner wall of the fixed cylinder. The output end of the servo motor passes through the fixed cylinder and is fixedly connected to a screw picker for picking up materials and fastening the pre-embedded screw parts.

[0010] As a preferred embodiment of an automatic pre-embedded screw device for side panels of panel furniture, the buffer assembly includes a rubber plate disposed on one side of a connecting plate, a movable rod that passes through the connecting plate fixedly connected to one side of the rubber plate, a sliding plate fixedly connected to one end of the movable rod, and a fixing spring that is fixedly connected to the connecting plate and the sliding plate sleeved on the surface of the movable rod.

[0011] As a preferred embodiment of an automatic pre-embedded screw device for side panels of panel furniture, the linkage component includes positioning frames symmetrically rotatably connected to both sides of a sliding plate, a movable plate rotatably connected to one side of the clamping plate, a card seat fixedly connected to one side of the movable plate, an elastic sheet fixedly connected to the inner bottom wall of the card seat, a locking bolt threaded to the top of the card seat, the bottom end of the locking bolt penetrating the top of the card seat and rotatably connected to a clamping plate, and the clamping plate slidingly connected to the inner wall of the card seat.

[0012] As a preferred embodiment of an automatic pre-embedded screw device for side panels of panel furniture, the movable plate is engaged and fixed inside the positioning frame, and the inner wall of the clamping plate is engaged and fixed outside the positioning frame; when the maximum travel of the board is blocked by the rubber plate, the sliding plate will slide synchronously and drive the clamping plate to slide relative to each other through the linkage structure of the positioning frame and the movable plate.

[0013] As a preferred embodiment of an automatic pre-embedded screw device for side panels of panel furniture, an adjustment assembly for adjusting the sliding distance of the connecting plate is provided on one side of the gantry frame. The adjustment assembly includes a right fixed frame fixedly connected to one side of the gantry frame. A drive motor is fixedly connected to one end of the right fixed frame. The output end of the drive motor extends into the interior of the right fixed frame and is fixedly connected to a threaded rod via a coupling. A threaded plate is threadedly connected to the surface of the threaded rod. An installation plate is fixedly connected to one side of the threaded plate. A fixing cylinder is fixedly connected to the bottom end of the installation plate. The output end of the fixing cylinder is fixedly connected to the top end of the connecting plate. Limiting rods penetrating the installation plate are symmetrically fixedly connected to the top end of the connecting plate.

[0014] As a preferred embodiment of an automatic pre-embedded screw device for side panels of panel furniture, a left fixed frame is fixedly connected to one side of the gantry frame, a sliding rod is fixedly connected to the inner wall of the left fixed frame, and a sliding plate that slides with the surface of the sliding rod is fixedly connected to one side of the mounting plate.

[0015] An automatic pre-embedding process for side panel screws in panel furniture, utilizing the aforementioned automatic pre-embedding device for side panel screws in panel furniture, includes the following steps: S1, first adjust the width between the clamping plates to meet the width of the plate, and simultaneously adjust the overall linkage length of the movable plate and the positioning frame; S2, the sheet metal is conveyed towards the gantry frame via the conveyor belt; S3, the buffer assembly buffers the contact with the plate, and the one-way check mechanism prevents the rubber roller from rotating in the opposite direction to limit the reverse slippage of the plate. At the same time, the linkage assembly makes the clamping plate slide relative to each other to clamp and fix the plate. S4, The pre-embedded component automatically picks up the screw pre-embedded part and pre-embeds it in the appropriate pre-embedded position of the plate; S5, the adjustment component can drive the anti-slip component to move, so as to meet the pre-embedded processing of different positions in the lateral direction of the plate; S6, after all the pre-embedded stations on the board are processed, the fixing cylinder is activated to raise the connecting plate, release the limit on the board, and facilitate the conveyor belt to transport the processed board to the next process.

[0016] The beneficial effects of this invention are as follows: 1. By setting up a buffer component, flexible contact between the plate and the connecting plate is achieved. On the one hand, this avoids edge and corner chipping and surface wear caused by direct hard collision between the plate and the connecting plate. On the other hand, it effectively buffers the inertial impact force when the plate is conveyed to the position, eliminating random slippage of the plate caused by hard collision. At the same time, the one-way check mechanism can realize the one-way rotation of one of the rubber rollers, forming a reverse mechanical lock on the plate. Combined with the clamping plate, it limits the two sides of the plate, fundamentally preventing the plate from slipping or slightly shifting due to the inertia of conveying or the reaction force of collision. This ensures the stability of the plate's position reference in the conveyor line, provides a reliable positioning basis for subsequent pre-embedded processing, significantly reduces the coordinate compensation load of the laser positioning system, reduces frequent correction and standby manual adjustment, and significantly improves the accuracy and consistency of pre-embedded processing.

[0017] The movement of the sliding plate, through the linkage component, causes the clamping plate to slide and further clamp the plate, achieving secondary reinforcement clamping after the plate is in place, further constraining the lateral degree of freedom of the plate and preventing slippage and deviation; at the same time, during the pre-embedded processing, this linkage clamping structure can continuously provide stable positioning for the plate, effectively resisting the shaking and displacement of the plate caused by processing vibration, improving the stability of screw pre-embedded parts screwing operation, and ensuring the coaxiality and processing accuracy of the pre-embedded hole position.

[0018] The clamping plate adopts a sliding and adjustable structural design, which can adaptively adjust the clamping spacing according to the width of the plate to achieve centered clamping of plates of different specifications and ensure the alignment of the plate conveying. At the same time, the adjustment component can change the distance between the connecting plate and the gantry, so that the equipment can meet the positioning requirements of the plate at different pre-embedded positions along the conveyor belt direction. It can be adapted to the mixed production of multiple specifications of plates without changing the tooling, which greatly improves the versatility and applicability of the equipment.

Detailed Implementation

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0032] In the accompanying drawings of the embodiments of the present invention, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention 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, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0033] In the description of this invention, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating a connection between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection via an intermediate medium; it can refer to a connection within two components or an interaction between two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0034] refer to Figures 1 to 9 This invention provides an automatic pre-embedding device for side panel screws in panel furniture, comprising a frame 1, a conveyor belt 3 rotatably connected inside the frame 1, a gantry frame 2 fixedly connected to the top of the frame 1, an anti-slip component 7 for clamping and positioning the panel on one side of the gantry frame 2, the anti-slip component 7 including a connecting plate 71 on one side of the gantry frame 2, a clamping plate 75 below the connecting plate 71, a rubber roller 76 rotatably connected to one side of the clamping plate 75, a one-way check mechanism 77 inside the clamping plate 75 to prevent the rubber roller 76 from rotating in the opposite direction, a buffer component 8 for preventing hard collisions of the panel on one side of the connecting plate 71, and a linkage component 6 for driving the clamping plate 75 to slide and clamp. When the panel is conveyed and comes into contact with the buffer component 8, the linkage component 6 can drive the clamping plate 75 to slide inward synchronously, clamping and limiting the side wall of the panel. In this example, a controller is installed at one end of the gantry frame 2 to facilitate automated control of the electrical equipment in this pre-embedding device.

[0035] Specifically, such as Figure 7 and Figure 9 As shown, the one-way check mechanism 77 includes a fixing groove 771 formed inside the clamping plate 75. A ratchet 772 is rotatably connected to the inner wall of the fixing groove 771. The bottom end of the ratchet 772 is fixedly connected to the top end of the rubber roller 76. A rotating rod 773 is rotatably connected to the inner wall of the fixing groove 771. A pawl 775 is fixedly connected to the outer side of the rotating rod 773 to prevent the ratchet 772 from rotating in the opposite direction. A torsion spring 774 is symmetrically sleeved on the outer side of the rotating rod 773 and fixedly connected to the inner wall of the fixing groove 771 and the surface of the pawl 775. The torsion spring 774 is used to realize the automatic reset of the pawl 775. In this example, the one-way check mechanism 77 can be set at the top of one of the rubber rollers 76 or each rubber roller 76 can be equipped with it, as long as it can achieve the purpose of preventing the plate from sliding in the opposite direction.

[0036] In this embodiment, when the plates 75 are clamped together during the plate conveying process, the rubber roller 76 rotates, which in turn drives the ratchet 772 to rotate, and causes the pawl 775 to deflect accordingly. When the plate is blocked by the connecting plate 71, the reaction force between the collisions will cause the plate to have a tendency to slide in the opposite direction. At this time, the ratchet 775 limits and engages the ratchet 772, which can prevent the rubber roller 76 from rotating in the opposite direction. Furthermore, the friction between the rubber roller 76 and the plate can be used to prevent the plate from sliding in the opposite direction.

[0037] Specifically, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the anti-slip assembly 7 also includes a sliding seat 74 slidably connected to the bottom end of the connecting plate 71. The bottom end of the sliding seat 74 is slidably connected to the top end of the clamping plate 75. A fixing bolt 72 that penetrates the connecting plate 71 is fixedly connected to the top end of the sliding seat 74. A fixing nut 73 is threadedly connected to the surface of the fixing bolt 72. The threaded engagement of the fixing bolt 72 and the fixing nut 73 can realize the position adjustment of the sliding seat 74.

[0038] In this embodiment, the fixing nut 73 is loosened by using tools such as a hex wrench, and then the sliding seat 74 is slid to drive the clamping plate 75 to slide. The scale value opened at the top of the connecting plate 71 can be used to clearly know the distance between the clamping plate 75 and the sliding distance, so that the distance between the two clamping plates 75 is equal to the width of the plate. Then the fixing nut 73 is tightened to achieve the limiting fixation of the sliding seat 74 after sliding.

[0039] Specifically, such as Figures 1 to 3 As shown, the gantry frame 2 is equipped with a pre-embedded component 5 for automatic material handling and pre-embedding of screws. The pre-embedded component 5 includes a linear feeder 51 fixedly connected to one end of the gantry frame 2. One end of the linear feeder 51 is connected to the feeding end of the vibratory feeder. An electric slide rail 53 is fixedly connected to the inner wall of the gantry frame 2. An electric slider 52 is slidably connected to the bottom end of the electric slide rail 53. A lifting cylinder 54 is fixedly connected to the bottom end of the electric slider 52. A fixed cylinder 57 is fixedly connected to the output end of the lifting cylinder 54. A laser sensor is installed at the bottom end of the fixed cylinder 57. A servo motor 55 is fixedly connected to the inner wall of the fixed cylinder 57. The output end of the servo motor 55 passes through the fixed cylinder 57 and is fixedly connected to a screw picker 56 for picking up and fastening the pre-embedded screw. In this example, the screw picker 56 is a fastening head in an existing automatic screw machine, which realizes the picking up, positioning and rotating of the pre-embedded screw. At the same time, limit switches are set on both sides of the electric slide rail 53 to prevent the electric slider 52 from moving excessively.

[0040] In this embodiment, the linear feeder 51 is connected to the vibratory feeder, thus ensuring uniform and neat automatic feeding of the screw pre-embedded parts. When the board material is conveyed to the appropriate position, the conveyor belt 3 stops working. Then, the electric slider 52 and the electric slide rail 53 work together to move the lifting cylinder 54 towards the linear feeder 51. The lifting cylinder 54 is then activated to lower the screw picker 56 to pick up the screw pre-embedded parts on one side of the linear feeder 51. After that, the electric slider 52 is activated to raise the screw picker 56, which in turn raises the screw pre-embedded parts. The electric slider 52 and the electric slide rail 53 work together to allow the screw pre-embedded parts to slide in the front and back direction of the board material. The laser sensor at the bottom of the fixed cylinder 57 can accurately move the screw pre-embedded parts to the designated pre-embedded position. The lifting cylinder 54 is then activated to lower the screw pre-embedded parts, and the servo motor 55 works to rotate the screw picker 56, which in turn presses down the screw pre-embedded parts for pre-embedded processing. Example

[0041] In the above embodiment 1, when the board is conveyed by the conveyor belt 3 and blocked by the connecting plate 71, it will undergo a hard collision, which can easily damage the surface of the board. It can also easily cause the board to slip due to the collision, resulting in a large computational load on the control system. If the slip distance is too large, the position of the board needs to be manually adjusted, which seriously reduces the efficiency of the board pre-embedding processing. In order to solve this problem, this embodiment provides a buffer component 8 that can buffer contact and a linkage component 6 that restricts the slip of the board.

[0042] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, the buffer assembly 8 includes a rubber plate 82 disposed on one side of the connecting plate 71. A movable rod 83 that passes through the connecting plate 71 is fixedly connected to one side of the rubber plate 82. A sliding plate 84 is fixedly connected to one end of the movable rod 83. A fixing spring 81 that is fixedly connected to the connecting plate 71 and the sliding plate 84 is sleeved on the surface of the movable rod 83.

[0043] In this embodiment, when the sheet is conveyed by the conveyor belt 3, one side of the sheet will first contact the rubber plate 82, causing the rubber plate 82 to slide and drive the movable rod 83 to slide and stretch the fixed spring 81. Thus, the material of the rubber plate 82 itself and the elasticity of the fixed spring 81 can be used to achieve flexible contact of the sheet, avoiding damage to the surface caused by hard collision with the connecting plate 71 or random slippage due to hard collision. At the same time, the friction between the rubber roller 76 and the sheet can also be used to prevent the sheet from slipping due to the elasticity of the fixed spring 81.

[0044] Specifically, such as Figure 2 , Figure 4 , Figure 5 and Figure 8As shown, the linkage component 6 includes positioning frames 62 symmetrically rotatably connected to both sides of the sliding plate 84, a movable plate 61 rotatably connected to one side of the clamping plate 75, a card seat 65 fixedly connected to one side of the movable plate 61, an elastic sheet 66 fixedly connected to the inner bottom wall of the card seat 65, a locking bolt 63 threadedly connected to the top of the card seat 65, the bottom end of the locking bolt 63 passing through the top of the card seat 65 and rotatably connected to a clamping plate 64, and the clamping plate 64 slidingly connected to the inner wall of the card seat 65.

[0045] Specifically, such as Figure 8 As shown, the movable plate 61 is internally engaged and fixed with the positioning frame 62, and the inner wall of the clamping plate 64 is engaged and fixed with the outer surface of the positioning frame 62. When the maximum stroke of the plate is blocked by the rubber plate 82, the sliding plate 84 will slide synchronously and drive the clamping plate 75 to slide relative to each other through the linkage structure of the positioning frame 62 and the movable plate 61.

[0046] In this embodiment, first, by loosening the locking bolt 63, the clamping plate 64 is completely separated from the top of the positioning frame 62. Then, the clamping seat 65 is moved to completely disengage the movable plate 61 from the inside of the positioning frame 62. After that, the sliding distance of the clamping plate 75 can be adjusted normally. After the clamping plate 75 is adjusted, the rotation angles of the movable plate 61 and the positioning frame 62 can be adjusted respectively, so that the movable plate 61 is locked into the inside of the positioning frame 62. Then, the locking bolt 63 is tightened so that the clamping plate 64 is pressed against the top of the positioning frame 62, and works in conjunction with the elastic sheet 6. The bottom end of the positioning frame 62 is clamped to ensure the firmness of the engagement between the movable plate 61 and the positioning frame 62. Then, when the plate is conveyed and comes into contact with the rubber plate 82, the sliding plate 84 will slide. Through the linkage between the positioning frame 62 and the movable plate 61, the clamping plate 75 slides at the bottom end of the sliding seat 74 towards the plate. The plate can be clamped by the two clamping plates 75, further preventing the plate from slipping due to conveying inertia, collision reaction force or the elasticity of the fixing spring 81, and improving the stability of the plate during pre-embedding processing.

[0047] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, an adjustment assembly 4 for adjusting the sliding distance of the connecting plate 71 is provided on one side of the gantry frame 2. The adjustment assembly 4 includes a right fixed frame 47 fixedly connected to one side of the conveyor belt 3. A drive motor 46 is fixedly connected to one end of the right fixed frame 47. The output end of the drive motor 46 extends into the interior of the right fixed frame 47 and is fixedly connected to a threaded rod 49 through a coupling. A threaded plate 410 is threadedly connected to the surface of the threaded rod 49. A mounting plate 41 is fixedly connected to one side of the threaded plate 410. A fixing cylinder 45 is fixedly connected to the bottom end of the mounting plate 41. The output end of the fixing cylinder 45 is fixedly connected to the top end of the connecting plate 71. A limiting rod 44 penetrating the mounting plate 41 is symmetrically fixedly connected to the top end of the connecting plate 71.

[0048] In this embodiment, the drive motor 46 is activated to rotate the threaded rod 49. The threaded engagement between the threaded rod 49 and the threaded plate 410 causes the threaded plate 410 to slide, which in turn causes the mounting plate 41 to slide, thereby causing the connecting plate 71 to slide. At the same time, the drive motor 46 precisely controls the number of rotations and angle of the threaded rod 49, thereby precisely adjusting the distance between the connecting plate 71 and one side of the gantry 2. This allows the positioning requirements of the pre-embedded work positions of the plate at different locations along the conveyor belt 3 to be met, improving its applicability. Simultaneously, the fixed cylinder 45 can be activated to lower the connecting plate 71, facilitating the conveying and limiting of the plate. After the fixed cylinder 45 operates and the connecting plate 71 rises, the limiting of the plate can be released, allowing the plate to be conveyed to the next process by the conveyor belt 3 after the pre-embedding processing is completed.

[0049] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, a left fixed frame 43 is fixedly connected to one side of the gantry frame 2, and a slide rod 48 is fixedly connected to the inner wall of the left fixed frame 43. A slide plate 42 that slides with the surface of the slide rod 48 is fixedly connected to one side of the mounting plate 41.

[0050] In this embodiment, the smoothness of the back-and-forth sliding adjustment of the mounting plate 41 is improved by utilizing the sliding between the sliding plate 42 and the sliding rod 48.

[0051] An automatic pre-embedding process for side panel screws in panel furniture, utilizing the aforementioned automatic pre-embedding device for side panel screws in panel furniture, includes the following steps: S1, first adjust the width between the clamping plates 75 to meet the width of the plate, and simultaneously adjust the overall linkage length of the movable plate 61 and the positioning frame 62. S2, the plates are conveyed to the gantry frame 2 via the conveyor belt 3; S3, the buffer component 8 buffers the contact with the plate, and the one-way check mechanism 77 prevents the rubber roller 76 from rotating in the opposite direction to limit the reverse sliding of the plate. At the same time, the linkage component 6 makes the clamping plate 75 slide relative to clamp and fix the plate. S4, automatically retrieve the screw pre-embedded parts through the pre-embedded component 5 and pre-embed them in the appropriate pre-embedded positions of the plate; S5, by adjusting component 4, the anti-slip component 7 can be moved to meet the pre-embedded processing of different positions in the lateral direction of the plate; S6. After all the pre-embedded workstations on the board are processed, the fixed cylinder 45 is activated to raise the connecting plate 71, releasing the limit on the board and making it easier for the conveyor belt 3 to transport the processed board to the next process.

Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to the present invention. However, such variations, as long as they do not depart from the spirit of the present invention, should be within the scope of protection of the present invention.
