Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, and in particular to a multi-station CNC drilling center for wood panel processing. Background Technology

[0002] The multi-station CNC drilling center for wood panel processing is a high-efficiency, high-precision automated processing equipment specifically designed for wood (especially engineered wood panels such as particleboard, medium-density fiberboard, and plywood). It is mainly used for batch drilling of wood panels and is widely used in the production of modern wood products such as panel furniture, cabinets, wardrobes, and office furniture.

[0003] Traditional multi-station CNC drilling equipment for wood panel processing commonly suffers from technical problems such as inconvenient loading and unloading and limited production efficiency. These machines typically employ a design mode where processing and loading / unloading occur at the same station or in the same area. This means that when drilling wood panels, operators cannot simultaneously load new workpieces or unload finished products. They must wait until the current processing cycle is completely finished before starting the next cycle, creating a sequential operation mode where loading cannot occur while processing is in progress, and processing cannot occur while loading is in progress. Furthermore, some machines lack effective automatic positioning and clamping mechanisms, requiring manual alignment of wood panels, resulting in low positioning accuracy and long processing time. Clamping devices are mostly fixed or manually adjustable, making it difficult to adapt to rapid switching between different sized boards, further increasing auxiliary time.

[0004] To address the aforementioned issues, a multi-station CNC drilling center for wood panel processing is needed that facilitates loading and unloading. Utility Model Content

[0005] To overcome the inconvenience of loading and unloading materials, this utility model provides a multi-station CNC drilling center for wood panel processing.

[0006] The technical solution of this utility model is as follows: a multi-station CNC drilling center for wood processing, comprising a worktable, a first electric slide rail, a first slider, a first sliding plate, a second electric slide rail, a second slider, a sliding frame, a third electric slide rail, a third slider, a mounting plate, an electric drill bit, a pneumatic gripper, a second sliding plate, a fixing plate, an electric push rod, a receiving plate, a placement plate, a mounting frame, a positioning block, a spring, a mounting rod, a roller, a connecting frame, and a pressing block. The first electric slide rails are symmetrically installed on the rear side of the top of the worktable, and first sliders are slidably connected to both first electric slide rails. A first sliding plate is slidably connected to the worktable, and two first sliders are connected to the first sliding plate. Second electric slide rails are symmetrically installed on the top front and rear of the first sliding plate, and second sliders are slidably connected to both second electric slide rails. A sliding frame is slidably connected to the first sliding plate, and two second sliders are connected to the sliding frame. Third electric slide rails are symmetrically installed on the front side of the sliding frame. Each of the two third electric slide rails has a third slider slidably connected to it. A mounting plate is connected between the front sides of the two third sliders. Four electric drill bits are mounted on the front side of the mounting plate. Four pneumatic grippers are installed inside the worktable. A second sliding plate is slidably connected to the front top of the worktable. A fixed plate is installed on the worktable. An electric push rod is installed inside the fixed plate. The telescopic end of the electric push rod is connected to the second sliding plate. Four receiving plates are connected to the rear side of the second sliding plate. Four placement plates are connected to the rear side of the second sliding plate. A mounting bracket is installed at the bottom of each placement plate. A positioning block is slidably connected to the two connecting rods at the bottom of each placement plate. A spring is symmetrically provided between each positioning block and the corresponding mounting bracket. The spring is sleeved in the connecting rod. Mounting rods are symmetrically installed on the rear side of each positioning block. Rollers are rotatably connected between each pair of adjacent mounting rods. A connecting frame is connected to the worktable. Four pressing blocks are evenly spaced at the bottom of the connecting frame.

[0007] As a preferred technical solution of this utility model, it also includes a limiting plate and a scale strip. Each placement plate is symmetrically connected to the limiting plate from left to right, and multiple scale strips are embedded inside each limiting plate.

[0008] As a preferred technical solution of this utility model, it also includes anti-slip pads, with each pneumatic gripper symmetrically provided with anti-slip pads on the left and right sides.

[0009] As a preferred technical solution of this utility model, it also includes a sponge pad, and each receiving plate is provided with a sponge pad.

[0010] As a preferred technical solution of this utility model, the bottom of each extrusion block is a slope.

[0011] As a preferred technical solution of this utility model, each roller is made of stainless steel.

[0012] The beneficial effects of this utility model are as follows: By setting up an independent double-layer sliding structure of a placement plate and a receiving plate, and cooperating with an electric push rod to drive the second sliding plate to move back and forth, the processing, loading and unloading are separated and operated in space and time in parallel. That is, while drilling is being processed, the operator can load new wooden boards onto the workstation that has been processed. This completely breaks the serial operation mode where loading cannot be done while processing and processing cannot be done while loading, greatly shortens the non-processing auxiliary time, and significantly improves the continuous operation capability and unit time output of the equipment.

Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0022] Example: A multi-station CNC drilling center for wood panel processing, such as... Figures 1-7As shown, the system includes a worktable 1, a first electric slide rail 2, a first slider 3, a first sliding plate 4, a second electric slide rail 5, a second slider 6, a sliding frame 7, a third electric slide rail 8, a third slider 9, a mounting plate 10, an electric drill bit 11, a pneumatic gripper 12, a second sliding plate 13, a fixing plate 14, an electric push rod 15, a receiving plate 16, a placement plate 17, a mounting frame 18, a positioning block 19, a spring 20, a mounting rod 21, a roller 22, a connecting frame 23, a pressing block 24, a limiting plate 25, a scale strip 26, an anti-slip pad 27, and a sponge pad 28. The first electric slide rails 2 are symmetrically installed on the left and right sides of the top rear of the worktable 1, serving as linear motion guides for the Y-axis (front-back direction). First sliders 3 are slidably connected to both first electric slide rails 2. A first sliding plate 4 is slidably connected to the workbench 1. Two first sliders 3 are connected to the first sliding plate 4. Second electric slide rails 5 are symmetrically mounted on the top of the first sliding plate 4, serving as linear motion guides for the X-axis (left-right direction). Second sliders 6 are slidably connected to both second electric slide rails 5. A sliding frame 7 is slidably connected to the first sliding plate 4. Two second sliders 6 are connected to the sliding frame 7. Third electric slide rails 8 are symmetrically mounted on the front side of the sliding frame 7, serving as linear motion guides for the Z-axis (up-down direction). Third sliders 9 are slidably connected to both third electric slide rails 8. A mounting plate 10 is connected between the front sides of the two third sliders 9. Four electric drill bits 11 are mounted on the front side of the mounting plate 10, serving as the core tools for drilling operations. Four electric drill bits 11 are installed inside the workbench 1. A pneumatic gripper 12 is used to clamp the workpiece, ensuring the wooden board is fixed in position during processing, preventing displacement or vibration, and improving drilling accuracy. A second sliding plate 13 is slidably connected to the front top of the worktable 1. A fixed plate 14 is installed on the worktable 1, and an electric push rod 15 is installed inside the fixed plate 14. The telescopic end of the electric push rod 15 is connected to the second sliding plate 13. Four receiving plates 16 are connected to the rear side of the second sliding plate 13, located below the placement plate 17 and longer, to receive the falling processed wooden board after the pneumatic gripper 12 is released, completing automatic unloading. Four placement plates 17 are connected to the rear side of the second sliding plate 13 for placing the wooden board to be processed. Each placement plate 17 has a mounting bracket 18 installed at its bottom. Positioning blocks 19 are slidably connected to both connecting rods for positioning the wooden board. Each positioning block 19 and its corresponding mounting bracket 18 are symmetrically fitted with springs 20, which are sleeved within the connecting rods. Mounting rods 21 are symmetrically mounted on the rear side of each positioning block 19. Rollers 22 are rotatably connected between every two adjacent mounting rods 21. Each roller 22 is made of stainless steel, possessing high strength, wear resistance, and corrosion resistance. A connecting frame 23 is connected to the worktable 1. Four pressing blocks 24 are evenly spaced at the bottom of the connecting frame 23. Each pressing block 24 has a sloped bottom. When the second sliding plate 13 moves, its slope gradually presses down on the rollers 22, forcing the positioning blocks to retract downwards against the spring force of the springs 20, achieving automatic avoidance.Each placement plate 17 has symmetrically sliding limit plates 25 inside to restrict the lateral (left-right) position of the wooden board. Each limit plate 25 has multiple graduated strips 26 embedded inside. Each pneumatic gripper 12 has symmetrically placed anti-slip pads 27, and each receiving plate 16 has a sponge pad 28.

[0023] At the start of the operation, the operator places four wooden boards to be processed onto the surfaces of the four placement plates 17 on the second sliding plate 13. The edges of the wooden boards abut against the limiting plate 25 and the positioning block 19, which is supported by the spring 20. The operator uses the scale strip 26 on the limiting plate 25 to adjust the size and achieve preliminary precise positioning. Then, the electric push rod 15 is activated, pushing the second sliding plate 13, together with the placement plates 17 and the wooden boards, forward. When they reach a certain position, the pressing block 24 at the bottom of the connecting frame 23 gradually presses down the roller 22 mounted on the mounting rod 21 with its inclined surface, forcing the positioning block 19 to overcome the elastic force of the spring 20 and move along the mounting frame 18. The board retracts downwards, thus detaching from the surface of the wooden board and avoiding interference with subsequent clamping actions. When the wooden board moves to the predetermined processing position, the four pneumatic grippers 12 inside the worktable 1 simultaneously clamp inwards, thus firmly clamping the four wooden boards and completing the clamping and positioning. At this time, the electric push rod 15 begins to retract, driving the second sliding plate 13 to return backwards. During the return stroke, the bottom of the clamped wooden board crosses the area of ​​the roller 22. Under the pressure of the wooden board, the roller 22 continues to press down on the positioning block 19 until the second sliding plate 13 is fully reset. After that, the roller 22 detaches from the wooden board, and the spring 20 restores its elasticity, causing the positioning block 19 to automatically return to the extended state, preparing for the next loading. Preparation; simultaneously, the clamped wooden boards enter the processing state. The CNC system controls the first electric slide rail 2 to drive the first sliding plate 4 to move along the front-to-back direction (Y-axis), the second electric slide rail 5 to drive the sliding frame 7 to move along the left-to-right direction (X-axis), and the third electric slide rail 8 to control the mounting plate 10 and the four electric drill bits 11 to feed along the up-down direction (Z-axis). Through three-axis linkage, precise drilling of multiple holes and depths is achieved on the four wooden boards. During the drilling process, the operator can simultaneously place new wooden boards to be processed on the rear placement plate 17, realizing parallel processing and loading. When a batch of wooden boards is drilled, the electric push rod 15 extends again. Pushing the second sliding plate 13 forward moves the longer receiving plate 16, which is located below the placement plate 17, to directly below the pneumatic gripper 12. Then, the pneumatic gripper 12 releases, and the processed wooden board falls vertically under gravity and is caught by the receiving plate 16. The sponge pad 28 on its surface can effectively buffer the impact and prevent damage. After unloading is completed, the electric push rod 15 moves the placement plate 17 to the position of the pneumatic gripper 12 to load the second batch of wooden boards. After loading is completed, the electric push rod 15 retracts, pulling the second sliding plate 13 back to the starting position. The operator can then remove the finished product and reload it. The equipment then enters the next work cycle.
