Description

Technical Field

[0001] This invention relates to wood drilling, and more specifically to the field of furniture manufacturing equipment technology, specifically to a board processing device for furniture manufacturing. Background Technology

[0002] In the modern furniture manufacturing industry, the board drilling process is the core link to achieve board splicing and hardware installation. Its processing efficiency and operational safety directly affect the company's production rhythm and employees' occupational health.

[0003] Existing board drilling equipment generally lacks specific anti-splash structures. During the high-speed rotation of the drill bit and the cutting of wood, a large amount of wood chips of uneven size are generated and splash outwards, increasing the frequency of equipment cleaning and maintenance. After drilling is completed, the drill bit needs to be withdrawn from the board and returned to its initial position. During this process, the high-speed rotating drill bit is completely exposed in the operating space, and there is a lack of immediate shielding and protection. Since furniture manufacturing workshops are mostly assembly line operations, operators need to frequently move between equipment to complete operations such as loading and unloading boards and adjusting parameters. They are prone to accidentally touching the drill bit that has not stopped due to distraction, resulting in serious safety accidents such as hand cuts and flesh entanglement. Although some existing equipment has attempted to add simple protection, it cannot form a full-cycle safety barrier before, during and after drilling, which greatly reduces its safety protection capability.

[0004] Meanwhile, to achieve stable fixing of the sheet metal, existing devices mostly use hydraulic clamps. These clamps require multiple sets of hydraulic rods to ensure uniform force on all edges and corners of the sheet metal. Each set of hydraulic rods requires a hydraulic pump, hydraulic hoses, solenoid valves, and other components, whose procurement costs account for a large proportion of the total procurement cost of the drilling device. For small and medium-sized furniture manufacturing enterprises, the high initial equipment investment significantly increases financial pressure and restricts the speed of equipment upgrades. Furthermore, hydraulic systems are complex to maintain, requiring precise adjustments that are time-consuming, increasing production costs and extending production cycles over long-term use. Therefore, this paper proposes a sheet metal processing device for furniture manufacturing to address the aforementioned problems. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a board processing device for furniture manufacturing, which has the following advantages:

[0020] 1. The board processing device used in furniture manufacturing adopts a combination of a protective section and a control section to achieve ring protection and airflow-assisted chip removal, reduce the range of wood chip splashing, and the ring structure shields the drill bit after drilling to reduce the risk of accidental contact, which complies with the safety specifications of furniture manufacturing workshops.

[0021] 2. The board processing device used in furniture manufacturing adopts a pneumatic control unit instead of traditional hydraulic clamps, eliminating the need for expensive parts procurement and maintenance, reducing initial equipment costs and maintenance costs. Only low-cost parts such as pull ropes and piston rings need to be replaced, making it suitable for the capital needs of small and medium-sized furniture enterprises.

[0022] 3. The board processing device for furniture manufacturing adopts precise positioning of the installation part and uniform clamping of the clamping part, combined with the precise drive of the three-axis displacement slide to improve drilling accuracy. The rubber chuck, together with the pressure sensor, monitors the current pressure threshold of the board to avoid damage to the board surface and improve the processing quality of furniture boards.

[0023] 4. The board processing device used in furniture manufacturing adopts a central control terminal to coordinate the actions of each module, from board feeding, protection, clamping, drilling to resetting and unloading, shortening the single processing cycle time, eliminating the need for frequent manual parameter adjustments, and allowing operators to monitor multiple devices simultaneously, thereby improving per capita production efficiency.

[0024] 5. The board processing device for furniture manufacturing adopts a two-way airflow control pipe to draw in air and store gas. The air pressure compensates for the clamping force of the clamping part and provides force relief and buffering when the control part is reset, which further improves the safety of use. When the two-way airflow control pipe sprays air, it can clean up the residual debris in the drilled hole, ensuring the clarity and cleanliness of the hole, and avoiding the wear of the hole wall by the debris during material feeding. The automated process reduces the operating burden of the operator. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-8This invention relates to a wood drilling device for furniture manufacturing. The device includes a worktable 1, a three-axis displacement slide 8, and a drill 9. The worktable 1 has a mounting section 2, providing a stable bearing reference for the wood and precise positioning and installation space for the protective section 3 and the control section 4, preventing drilling accuracy from being affected by component misalignment or wood offset. The mounting section 2 has a protective section 3, forming a full-cycle safety barrier before, during, and after drilling, blocking sawdust splashing and preventing operators from accidentally touching a drill bit that has not stopped. It also provides an installation and guiding carrier for the clamping section 5. The protective section 3 includes a protective plate 31 and a splash guard 32, which are fixedly connected. Both the protective plate 31 and the splash guard 32 are annular structures, and the inner and outer walls of the splash guard 32 are conical structures. The protective section 3 has a control section 4. The control unit 4 includes a sleeve 41, an air port 42 connected to the sleeve 41, a hose 43 connected to the air port 42, and a bidirectional airflow control pipe 44 connected to the end of the hose 43. It has a built-in electromagnetic reversing valve. By switching the valve state, the air intake channel is opened when the power is on and the air jet channel is opened when the power is off, so as to realize the rapid switching of airflow mode. A piston rod 45 is provided on the inner wall of the sleeve 41. The two ends of the piston rod 45 slide through the two ends of the sleeve 41 respectively. A piston ring 46 is fitted on the piston rod 45 and is slidably connected to the inner wall of the sleeve 41 through the piston ring 46. A pressure head 47 is fixedly connected to one end of the piston rod 45. A pressure sensor 48 is installed on the pressure head 47. The other end of the piston rod 45 is a U-shaped structure and is fitted with a collar 49. A tension spring 410 is elastically connected between the collar 49 and the sleeve 41. A rope ring 411 is fixedly connected to the U-shaped surface of the piston rod 45.

[0036] In this invention, the mounting part 2 includes a loading platform 21, which is centrally mounted on the top of the workbench 1. Furniture panels 22 are mounted on the loading platform 21. Guide rods 23 are fixedly connected to both sides of the workbench 1. A magnet 24 is mounted on the top of the workbench 1. Mounting holes 25 and adjustment holes 26 are provided at the four corners of the top of the workbench 1.

[0037] Furthermore, a low-cost pneumatic structure is used to replace the hydraulic clamp, providing a controllable clamping force for the clamping part 5 to prevent the plate from being crushed or loosened; at the same time, the anti-splash and chip collection effects are enhanced by airflow switching, improving the processing environment. There are four control parts 4, and the sleeves 41 in the four control parts 4 are fixedly connected to the four mounting holes 25 respectively. The U-shaped ends of the piston rods 45 in the four control parts 4 are slidably connected to the four adjustment holes 26 respectively.

[0038] In this embodiment, the protective part 3 also includes a second magnet 33, which is fixedly connected to the inner wall of the protective plate 31. The second magnet 33 and the first magnet 24 are magnetically attracted to each other. The splash plate 32 is provided with a guide hole 34 corresponding to the guide rod 23. The guide rod 23 is slidably connected to the corresponding guide hole 34. The inner wall of the protective plate 31 is fixedly connected with a positioning ring 35. The bottom of the protective plate 31 is in contact with the U-shaped ends of the four piston rods 45.

[0039] Furthermore, the protective part 3 is provided with a clamping part 5 to evenly clamp the plate and prevent it from shifting or lifting during drilling. The rubber material protects the surface of the plate and ensures accurate drilling position. The clamping part 5 includes a sliding hole 51, which is opened on the positioning ring 35. A slider 52 is slidably connected to the inner wall of the sliding hole 51. A chuck 53 is fixedly connected to one side of the slider 52. The chuck 53 is made of rubber. A limit rod 54 is fixedly connected to the slider 52. The limit rod 54 has a U-shaped structure. The two ears of the limit rod 54 slide through the positioning ring 35 and the splash guard 32 in sequence. The U-shaped surface of the limit rod 54 is located outside the splash guard 32. There are four clamping parts 5. The sliding holes 51 in the four clamping parts 5 are opened around the positioning ring 35. The four clamping parts 5 are respectively aligned with the four control parts 4. The U-shaped surfaces of the limit rods 54 in the four clamping parts 5 respectively abut against the pressure heads 47 in the four control parts 4.

[0040] Furthermore, a three-axis displacement slide 8 is installed on the worktable 1. A drill 9 is installed on the Z-axis slide of the three-axis displacement slide 8. The bidirectional airflow control pipe 44 in the four control parts 4 is installed around the drill 9. The drill bit of the drill 9 faces the furniture panel 22. The chucks 53 in the four clamping parts 5 are all in contact with the furniture panel 22.

[0041] It is worth noting that an equipment section 6 is provided below the workbench 1, which provides a closed protective space for the core control components, reduces wood chips and dust pollution, extends the life of the components, and integrates the equipment structure to reduce the floor space. The equipment section 6 includes a base 61, which is a hollow structure and is installed at the bottom of the workbench 1. A partition 62 is fixedly connected to the middle of the inner wall of the base 61, which divides the interior of the base 61 into an upper area and a lower area. A door 63 corresponding to the upper and lower areas is installed on the base 61. The U-shaped ends of the four piston rods 45 are located in the upper area.

[0042] It is worth noting that the equipment section 6 is equipped with a control section 7 to ensure the synchronous operation of the four control sections 4, guaranteeing uniform clamping force; it also assists the control sections 4 in their operation, automating protection and clamping, and improving processing efficiency. The control section 7 includes a housing 72, which is mounted on the partition plate 62. A gear 73 is centrally located inside the housing 72. Limiting plates 74 are fixedly connected to the four sides of the inner wall of the housing 72. Each of the four limiting plates 74 is slidably connected to the inner wall of the housing 72 with a rack 75. The four racks 75 slide through the four sides of the outer wall of the housing 72. The axes of the four control units 4 are respectively oriented. Each rack 75 is connected to a pull rope 76 between it and the corresponding rope ring 411. The lower area of ​​the base 61 is equipped with a wood drilling equipment control terminal and a motor 71. The wood drilling equipment control terminal coordinates the operation of the motor 71, drilling machine 9, three-axis displacement slide 8 and electromagnetic reversing valve module to realize full-process automated control. The motor 71 is equipped with an output shaft brake and is installed on the partition plate 62. The output shaft of the motor 71 passes through the housing 72 and is fixedly connected to the gear 73. The gear 73 meshes with the four racks 75.

[0043] Working principle: The operator places the furniture veneer 22 on the loading platform 21, ensuring the veneer is centered. The operator starts the motor 71 through the main control terminal of the wood drilling equipment and energizes the electromagnetic reversing valve to open the air intake channel. This causes the gear 73 to rotate, synchronously driving the four racks 75 to retract into the machine housing 72 under the limit plate 74. At the same time, the four pull ropes 76 are pulled synchronously, pulling the piston rod 45 on the rope ring 411. The piston rod 45 drives the piston ring 46 to slide in the sleeve 41 and generate negative pressure suction, causing gas to enter the hose from the air intake channel of the bidirectional airflow control pipe 44 and enter the sleeve 41 from the air port 42. This fills the inside of the sleeve 41 and the part above the piston ring 46 with gas, which provides a buffer effect for subsequent resetting. The piston rod 45 descends and at the same time stretches the tension spring 410 through the collar 49 to deform, preparing for subsequent resetting.

[0044] The bottom of the protective plate 31 contacts the U-shaped end of the piston rod 45. When the piston rod 45 descends, the protective plate 31, under its own weight, descends along the guide rod 23, thereby surrounding and shielding the loading platform 21 and the furniture panel 22. The splash guard 32 further shields the drilling area, reducing the amount of debris splashing. The positioning ring 35 descends with the protective plate 31, causing the clamp 53 to contact the upper surface of the furniture panel 22. The slider 52 slides along the sliding hole 51 to adapt to the thickness of the furniture panel 22. At the same time, the limiting rod 54 slides with the slider 52. At this time, the pressure head 47 descends with the piston rod 45, and the limiting rod 54 slides upward with the slider 52. The pressure head 47 contacts the U-shaped surface of the limiting rod 54 and triggers the pressure sensor 48 to ensure that the panel is centered and feeds the signal back to the terminal. When the pressure signal reaches the current pressure threshold of the furniture panel 22, the motor 71 is stopped and its output shaft brake is triggered to lock, preventing the gear 73 from rotating. This automatically completes the shielding, protection and clamping of the furniture panel 22.

[0045] The three-axis displacement slide 8 drives the drill 9 to adjust the drilling position and perform drilling operations. After the drilling operation is completed, the terminal releases the output shaft brake of the motor 71 and disconnects the electromagnetic reversing valve. At this time, the gear 73 is allowed to rotate, the tension spring 410 elastically contracts and resets, and pulls the piston rod 45 upward through the collar 49. The rope ring 411 pulls the rack 75 out of the housing 72 through the pull rope 76. At the same time, the piston ring 46 squeezes the gas in the sleeve 41, which is then sprayed out from the jet channel through the hose 43 to the bidirectional airflow control pipe 44 to blow air onto the drilling part of the furniture veneer 22 to ensure that the drilling part is clearly visible.

[0046] The U-shaped end of the piston rod 45 pushes the protective plate 31 up along the guide rod 23 and away from the workbench 1. The second magnet 33 moves away from the first magnet 24, the furniture panel 22 is exposed again, the chuck 53 moves away from the furniture panel 22 to release the clamping pressure, and finally the drill 9 is reset. The drill bit is located in the protective plate 31 after being raised and reset, which improves safety and makes it easier for the operator to unload materials.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
