Description

Technical Field

[0001] The utility model relates to the technical field of furniture plate processing, in particular to a furniture plate CNC processing center with an automatic loading and unloading device. Background Art

[0002] During the processing of furniture panels, corresponding CNC processing devices are required to process them. Reference is made to a CNC machine tool processing center for panel furniture production lines with publication number CN211840968U, which includes: a workbench arranged in a U-shaped structure; electric conveyor belts are embedded on all four sides of the workbench, which has high processing efficiency, saves labor costs, and has a high degree of automation. As described in the above patent, when using the existing furniture panel processing center with automatic loading and unloading devices, it is difficult to adjust the angle of the punching end of the device, or adjust the distance between the device and the panel, and adjust the punching position (the position of the hole along the X-axis and Y-axis directions) according to the user's processing needs. These greatly affect the adaptability of the device to panels of different sizes and the processing accuracy. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a CNC machining center for furniture panels with an automatic loading and unloading device, which solves the problems that the device is difficult to adjust the position and angle of the punching end as required, affecting the adaptability and machining accuracy of the device.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A CNC machining center for furniture panels with an automatic loading and unloading device includes a base plate, on which are mounted processing parts for processing furniture panels, the processing parts including:

[0005] A conveying roller assembly is mounted on the bottom plate and is used for automatic loading and unloading of plates; a first gap is formed between the conveying roller assembly and the bottom plate;

[0006] A numerically controlled adjustment member for performing a punching process on a plate, the numerically controlled adjustment member comprising a mounting frame disposed in the first gap and mounted on the base plate, the mounting frame being rotatably connected to a first one-way screw driven by a first motor along an X-axis, the first one-way screw being threadedly connected to a movable frame slidably connected to the mounting frame, the movable frame being rotatably connected to a second one-way screw driven by a second motor along a Y-axis, the second one-way screw being threadedly connected to a movable block slidably connected to the movable frame, the movable block being mounted with a punching member for adjusting an angle of a punching end;

[0007] The limiting member is installed on the bottom plate and is used for limiting the position of the plate.

[0008] Preferably, the fixed end of the first motor is mounted on the mounting frame, the output end of the first motor is coaxially fixedly connected to the first one-way screw, the fixed end of the second motor is mounted on the movable frame, and the second motor is coaxially fixedly connected to the second one-way screw.

[0009] Preferably, the punching member includes a rotating frame, which is rotatably connected to the end face of the moving block away from the moving frame in the X-axis direction, a third motor is installed on the top of the rotating frame, and a screw rod driven by the third motor is vertically rotatably connected in the rotating frame, and the screw rod is threadedly connected to a telescopic frame, and one end of the telescopic frame along the Z-axis direction is slidably connected to the rotating frame, and the end of the telescopic frame away from the connection with the rotating frame is placed outside the moving frame and extends outward along the X-axis direction to form an extension part, and a punch is vertically installed on the extension part, and a rotating cylinder for driving the rotating frame to rotate is installed on the end face of the moving block close to the moving frame in the X-axis direction.

[0010] Specifically, the bottom plate is a rectangle, the X axis is the long side direction of the rectangle, and the Y axis is the short side direction of the rectangle.

[0011] Preferably, the output end of the third motor is coaxially fixedly connected to the screw rod, and the extended end of the rotary cylinder is fixedly connected to the rotating end of the rotating frame.

[0012] Preferably, the limiting member includes at least one group of electric push rod assemblies vertically arranged on the base plate and distributed on both sides of the conveying roller assembly along the Y-axis direction, and each of the electric push rod assemblies is installed with a baffle at the end close to the conveying roller assembly along its extension direction, and the baffle is arranged on the top of the conveying roller assembly, and each of the baffles is provided with a fourth motor, and the output end of the fourth motor is coaxially fixedly connected with a bidirectional screw, and the front and rear ends of the bidirectional screw close to the upper side of the conveying roller assembly are threadedly connected with a group of limiting frames, and the limiting frames can move along the Y-axis direction under the rotation of the bidirectional screw to clamp and limit the plate.

[0013] Preferably, the limiting member includes two groups of electric push rod assemblies, and the number of electric push rod assemblies in each group of electric push rod assemblies is 2.

[0014] Specifically, when a sheet material is delivered to its designated location for processing, the fourth motor on each baffle is activated. A bidirectional screw, coaxially fixed to the output end of the fourth motor, rotates along the Y-axis and connects to the baffle. As the bidirectional screw rotates, a set of limit frames, threadedly connected to the front and rear ends of the bidirectional screw near the upper side of the conveyor roller assembly, begin to move. Due to the bidirectional thread structure of the bidirectional screw, the two sets of limit frames simultaneously approach the front and rear sides of the sheet material, clamping and limiting the front and rear ends of the sheet material. This greatly improves the sheet material's stability during subsequent processing, ensuring processing accuracy and quality.

[0015] Preferably, the bidirectional screw is rotatably connected to the baffle along the Y-axis, and square grooves are provided on both sides of the baffle for sliding connection with the limit frame.

[0016] Specifically, the square groove provides a precise movement path for the limit frame. When the fourth motor drives the bidirectional screw to rotate, the limit frame, threaded onto the bidirectional screw, moves along the screw's axial direction. The presence of the square groove ensures that the limit frame can slide smoothly in a specific direction, preventing instability such as deviation, shaking, or rotation during movement, thereby ensuring that the limit frame can accurately clamp and limit the front and back sides of the plate.

[0018] The utility model provides a CNC machining center for furniture panels with an automatic loading and unloading device. Compared with the existing technology, it has the following advantages:

The rotating cylinder in the punching part adjusts the rotating frame, the third motor, the screw rod, the telescopic frame, and the puncher angle. The third motor cooperates with the screw rod to adjust the distance between the telescopic frame, the puncher and the panel, thereby facilitating the user to perform punching processing at corresponding angles on corresponding positions of corresponding panels as needed, thereby improving the adaptability and processing accuracy of the device to different panels.

[0020] (2) The furniture panel CNC machining center with automatic loading and unloading device sets a limiter in the device, allowing the electric push rod assembly to adjust the height of the two sets of baffles, the fourth motor, the bidirectional screw, and the limit frame, so that the baffle limits the panels conveyed by the conveyor roller assembly and facilitates the unloading of the processed panels. Then, the fourth motor cooperates with the bidirectional screw to drive the two sets of limit frames to clamp and limit the front and rear sides of the panels, thereby improving the stability of the panels during the subsequent processing of the panels.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See Figures 1-4 , the utility model provides the following two technical solutions:

[0028] First embodiment: A CNC machining center for furniture panels with an automatic loading and unloading device includes a base plate 1, which is rectangular, with the X-axis being the long side of the rectangle. A processing part for processing furniture panels is mounted on the base plate 1, and the processing part includes:

[0029] The conveying roller assembly 2 is installed on the bottom plate 1 and is used for automatic loading and unloading of plates; a first gap is formed between the conveying roller assembly 2 and the bottom plate 1;

[0030] A numerical control adjusting member 3 is used for punching the plate. The numerical control adjusting member 3 includes a mounting frame arranged in the first gap and mounted on the base plate 1. The mounting frame is rotatably connected to a first one-way screw 32 driven by a first motor 31 along the X-axis. The first one-way screw 32 is threadedly connected to a moving frame 33 slidably connected to the mounting frame. The moving frame 33 is rotatably connected to a second one-way screw 35 driven by a second motor 34 along the Y-axis. The second one-way screw 35 is threadedly connected to a moving block 36 slidably connected to the moving frame 33. A punching member 37 for adjusting the angle of the punching end is mounted on the moving block 36.

[0031] The limiting member 4 is installed on the bottom plate 1 and is used for limiting the position of the plate;

[0032] The fixed end of the first motor 31 is mounted on the mounting frame, and the output end of the first motor 31 is coaxially fixedly connected to the first one-way screw 32. The fixed end of the second motor 31 is mounted on the moving frame 33, and the second motor 34 is coaxially fixedly connected to the second one-way screw 35.

[0033] The punching member 37 includes a rotating frame 371, which is rotatably connected to the end face of the moving block 36 away from the moving frame 33 in the X-axis direction. A third motor 372 is installed on the top of the rotating frame 371. A screw rod 373 driven by the third motor 372 is vertically rotatably connected inside the rotating frame 371. The screw rod 373 is threadedly connected to a telescopic frame 374. One end of the telescopic frame 374 along the Z-axis direction is slidably connected to the rotating frame 371. The end of the telescopic frame 374 away from the connection with the rotating frame 371 is placed outside the moving frame 371 and extends outwardly along the X-axis direction to form an extension portion. A punch 375 is vertically installed on the extension portion. A rotating cylinder 376 for driving the rotating frame 371 to rotate is installed on the end face of the moving block 36 close to the moving frame 33 in the X-axis direction.

[0034] The output end of the third motor 372 is coaxially fixedly connected to the screw rod 373, and the extended end of the rotary cylinder 376 is fixedly connected to the rotating end of the rotating frame 371; the first motor 31, the first one-way screw rod 32, the moving frame 33, the second motor 34, the second one-way screw rod 35, and the moving block 36 cooperate with each other to adjust the position of the punching member 37 along the X-axis and the Y-axis respectively. The rotary cylinder 376 in the punching member 37 adjusts the angle of the rotating frame 371, the third motor 372, the screw rod 373, the telescopic frame 374, and the punch 375. The third motor 372 cooperates with the screw rod 373 to adjust the distance between the telescopic frame 374, the punch 375 and the plate to facilitate effective punching;

[0035] The second embodiment differs from the first embodiment mainly in that:

[0036] The limiting member 4 includes at least one set of electric push rod assemblies 41 vertically arranged on the base plate 1 and distributed on both sides of the conveyor roller assembly 2 along the Y-axis direction. Each electric push rod assembly 41 is installed with a baffle 42 at the end close to the conveyor roller assembly 2 along its extension direction. The baffle 42 is arranged on the top of the conveyor roller assembly 2. Each baffle 42 is provided with a fourth motor 43. The output end of the fourth motor 43 is coaxially fixedly connected to a bidirectional screw 44. The front and rear ends of the bidirectional screw 44 near the upper side of the conveyor roller assembly 2 are threadedly connected to a set of limit frames 45. The limit frames 45 can move along the Y-axis direction under the rotation of the bidirectional screw 44 to clamp and limit the plate.

[0037] The bidirectional screw 44 is connected to the baffle 42 and rotates along the Y axis. Square grooves are provided on both sides of the baffle 42, which are slidably connected to the limit frame 45. The height of the two groups of baffles 42, the fourth motor 43, the bidirectional screw 44, and the limit frame 45 are adjusted by the electric push rod assembly 41, so that the baffle 42 limits the plate conveyed by the conveyor roller assembly 2 and facilitates the unloading of the processed plate. Then the fourth motor 43 cooperates with the bidirectional screw 44 to drive the two groups of limit frames 45 to clamp and limit the front and rear sides of the plate.

[0038] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0039] During use, the user conveys the furniture board to be processed toward the CNC adjustment part 3 through the conveying roller assembly 2. When the board moves and is located between the two sets of baffles 42, the height of the baffle 42, the fourth motor 43, the bidirectional screw 44, and the limit frame 45 are adjusted by the electric push rod assembly 41 so that the bottom of the two sets of baffles 42 are close to the upper side of the conveying roller assembly 2. After the board contacts the baffle 42 on the left side of the device, the conveying roller assembly 2 is closed, and the fourth motor 43 and the bidirectional screw 44 are coordinated to drive the two sets of limit frames 45 to clamp and limit the front and rear sides of the board. The first motor 31 is started. The first motor 31 drives the first unidirectional screw 32 to rotate, so that the first unidirectional screw 32 adjusts the position of the moving frame 33, the second motor 34, the second unidirectional screw 35, the moving block 36, and the punching member 37 along the X-axis.

[0040] After the punching member 37 is in the appropriate position on the X-axis, turn off the first motor 31, and let the second motor 34 cooperate with the second one-way screw 35 to adjust the Y-axis position of the moving block 36 and the punching member 37, and then let the rotating cylinder 376 adjust the angle of the rotating frame 371, the third motor 372, the screw rod 373, the telescopic frame 374, and the puncher 375. Turn on the puncher 375, let the third motor 372 cooperate with the screw rod 373 and the telescopic frame 374, and adjust the distance between the puncher 375 and the plate so that the puncher 375 punches the corresponding position of the plate at the corresponding angle. The puncher 375 and the rotating cylinder 376 are both existing technologies, so their internal specific structure and working principle will not be described in detail.
