Description

Technical Field

[0002] Currently, panel furniture is widely used. It is mainly made of particleboard, density board, multi-layer board, ecological board, etc., with veneer panels on the surface. After cutting, the side of the board is finely trimmed and glued before the edge banding is pasted. Due to the different physical properties of the board used for panel furniture, after cutting and sawing, the cut end surface is uneven or has saw marks, waves, etc. If the edge is directly sealed, the edge banding is difficult to fit, and obvious glue lines or overflow will occur.

[0003] A trimming device is usually used to trim the cut end face of the plate.

[0004] However, the above-mentioned end milling device is only applicable to straight plates and cannot meet the processing requirements for the end trimming of arc plates.

DETAILED DESCRIPTION

[0034] The present invention provides a circular arc plate end face trimming device and a circular arc plate edge sealing and trimming method. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and 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, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0036] Example 1

[0037] Please refer to Figures 1 to 4 This embodiment discloses a device for trimming the end face of an arc plate, comprising:

[0038] An operating table 10, on which a processing area 11 for placing the arc plate 80 is provided;

[0039] An x-axis driving mechanism 20 is provided on at least one side of the processing area 11 along the y-direction;

[0040] A z-axis driving mechanism 30 connected to a driving end of the x-axis driving mechanism 20;

[0041] The milling cutter mechanism 40 is connected to the driving end of the z-axis driving mechanism 30 and is used for trimming the end surface of the arc plate 80 .

[0042] The arc plate end face trimming device of the present embodiment, during processing, first places the arc plate 80 on the processing area 11 of the operating table 10, and makes the end face of the arc plate 80 face the milling cutter mechanism 40, and pre-designs the trajectory of the milling cutter mechanism 40 according to the shape of the arc plate 80, and sets the trajectory in advance in the corresponding control system, and the control system controls the operation of the x-axis drive mechanism 20 and the z-axis drive mechanism 30, so that the milling cutter mechanism 40 can move along the predetermined trajectory, and trim the end face of the arc plate 80 while walking, so that the end face of the arc plate 80 is made smoother by trimming, which is convenient for subsequent glue sealing.

[0043] Moreover, this embodiment can design different arc tracks according to the shape of the arc plate 80, and can adapt to the trimming of most arc plates 80 of different sizes and shapes without the need to design additional arc tracks, thus having better compatibility.

[0044] As a preferred embodiment, the x-axis drive mechanism 20 and the z-axis drive mechanism 30 of this embodiment adopt a screw module. The working principle of the screw module is to convert rotary motion into linear motion. This conversion is achieved by a ball screw, which consists of a screw, a nut and a ball. It can convert rotary motion into linear motion and achieve high-precision linear motion under high load conditions. The screw module has the characteristics of fast movement speed and high repeatability, which makes it perform well in applications that require fast and precise position control. In addition, the screw module body is light in weight and occupies a small space in the equipment, which is very suitable for application scenarios with limited space. The screw module has high torsional rigidity and can accurately control the rotation of the shaft to achieve high-precision control. This is achieved by using friction combination for transmission and a transmission method without gaps. This design can also compensate for radial, angular and axial deviations to ensure the stability and accuracy of the equipment. The same clockwise and counterclockwise rotation characteristics and the clamping method further enhance the reliability and durability of the screw module.

[0045] It should be noted that the x-axis drive mechanism 20 and the z-axis drive mechanism 30 of this embodiment use a screw module, which is only a preferred implementation. In other implementations, linear drive devices such as pneumatic cylinders, hydraulic motors, and worm gear transmissions can also be used, and are not limited to the screw module of this embodiment.

[0046] Please refer to Figure 1 and Figure 2 The arc plate end face trimming device of this embodiment also includes a y-axis limiting mechanism 50, which includes a first baffle 51 arranged on one side of the processing area 11 along the y-axis. The first baffle 51 is located between the processing area 11 and the x-axis driving mechanism 20, and is used to limit the end face of the arc plate 80, thereby correcting the placement angle of the end face of the arc plate 80, which is convenient for the subsequent milling cutter mechanism 40 to trim the end face of the arc plate 80.

[0047] Furthermore, in order to prevent the first baffle 51 from affecting the correction work of the milling cutter mechanism 40 on the end face of the arc plate 80, the y-axis limiting mechanism 50 of this embodiment also includes a first driving device 52 for driving the first baffle 51 to move along the z-axis. When it is necessary to correct the placement angle of the end face of the arc plate 80, the first driving device 52 can be used to drive the first baffle 51 to rise along the z-axis, and then one end face of the arc plate 80 is pressed against the side face of the first baffle 51 along the y-axis. After the adjustment is completed, the first driving device 52 is used to drive the first baffle 51 to lower its height along the z-axis, so that when the subsequent milling cutter mechanism 40 moves along the arc trajectory, the milling cutter mechanism 40 can trim the end face of the arc plate 80.

[0048] Furthermore, the first drive device 52 of this embodiment can be an electric cylinder. The electric cylinder is small and lighter, and can be directly connected to the drive motor. It no longer requires a pump, oil tank, and pipeline, etc. It is safer and more environmentally friendly, with lower noise. In addition, the electric cylinder has a fast response speed and can quickly drive the first baffle 51 to adjust the z-direction position. Of course, the first drive device 52 of this embodiment uses an electric cylinder, which is only a preferred embodiment. In other embodiments, linear drive devices such as pneumatic cylinders, hydraulic cylinders, and screw modules can also be used, and are not limited to the electric cylinder of this embodiment.

[0049] Please refer to Figure 2 The arc plate end face trimming device of this embodiment also includes an x-axis limiting mechanism 60. The x-axis limiting mechanism 60 includes a second baffle 61 and a third baffle 62 arranged on both sides of the processing area 11 along the x-axis. The spacing between the second baffle 61 and the third baffle 62 is adjustable and can adapt to arc plates 80 of different widths. The second baffle 61 and the third baffle 62 are used to limit the arc plate 80 placed therebetween to prevent the arc plate 80 from shaking during trimming, thereby ensuring the trimming effect.

[0050] Furthermore, the second baffle 61 of the present embodiment is fixed to the operating table 10, and the x-axis limiting mechanism 60 also includes a second driving device 63 driven along the x-axis, and the third baffle 62 is connected to the driving end of the second driving device 63. Specifically, the position of the third baffle 62 along the x-axis is controlled by the second driving device 63, thereby adjusting the distance between the second baffle 61 and the third baffle 62.

[0051] The second drive device 63 of this embodiment can be an electric cylinder. The electric cylinder is small and lighter. It can be directly connected to the drive motor, and no longer requires a pump, oil tank, and pipeline. It is safer, more environmentally friendly, and has lower noise. In addition, the electric cylinder has a fast response speed and can quickly drive the third baffle 62 to adjust the x-direction position. Of course, the second drive device 63 of this embodiment uses an electric cylinder, which is only a preferred embodiment. In other embodiments, linear drive devices such as pneumatic cylinders, hydraulic cylinders, and screw modules can also be used, and are not limited to the electric cylinder of this embodiment.

[0052] The milling cutter mechanism 40 of this embodiment includes a motor 41 fixed to the driving end of the z-axis driving mechanism 30 and a milling cutter 42 connected to the output shaft of the motor 41. The specific structure of the milling cutter 42 will not be described in detail below. The milling cutter 42 can adopt a milling cutter of the prior art, such as a disc milling cutter disclosed in Chinese patent publication number CN112606139A for preventing glue overflow during edge sealing of sheet materials.

[0053] In addition, this embodiment also discloses a circular arc plate edge sealing and trimming method, using a circular arc plate end surface trimming device, comprising the following steps:

[0054] S0 uses the first driving device 52 to drive the first baffle 51 to rise along the z direction;

[0055] S1: placing the arc plate 80 in the processing area 11, so that the end surface of the arc plate 80 along the length direction faces the milling cutter mechanism 40, and one end surface of the arc plate 80 is closely attached to the side surface of the first baffle 51 along the y direction;

[0056] S11 uses the first driving device 52 to drive the first baffle 51 to lower along the z direction;

[0057] S12 The second driving device 63 controls the third baffle plate 62 to move along the x direction, and the arc plate 80 is clamped by the second baffle plate 61 and the third baffle plate 62;

[0058] S2 utilizes the x-axis driving mechanism 20 and the z-axis driving mechanism 30 to drive the milling cutter mechanism 40 to move out of the arc track, and the milling cutter mechanism 40 trims the end surface of the arc plate 80 while moving.

[0059] Example 2

[0060] Please refer to Figure 5 and Figure 6 Compared with Example 1, the main difference of this embodiment is that the arc plate end face trimming device also includes a z-direction limiting mechanism 70, the z-direction limiting mechanism 70 includes a third driving device 71 arranged above the processing area 11 along the z-direction and driven along the z-direction, and a pressing member 72 connected to the driving end of the third driving device 71. The pressing member 72 is used to press the arc plate 80 along the z-direction. Before processing, the pressing member 72 is driven to descend by the third driving device 71, and the pressing member 72 is used to press the upper end surface of the arc plate 80 to prevent the arc plate 80 from shaking, thereby ensuring the smooth progress of the trimming action.

[0061] The third driving device 71 of this embodiment can adopt an electric cylinder. The electric cylinder is small and lighter, and can be directly connected to the driving motor. It no longer needs a pump, oil tank, and pipeline, etc. It is safer and more environmentally friendly, with lower noise. In addition, the electric cylinder has a fast response speed and can quickly drive the pressing member 72 to rise or lower. Of course, the third driving device 71 of this embodiment adopts an electric cylinder, which is only a preferred embodiment. In other embodiments, linear driving devices such as pneumatic cylinders, hydraulic cylinders, and screw modules can also be used, and are not limited to the electric cylinder of this embodiment.

[0062] Furthermore, the pressing member 72 of the present embodiment is a suction cup, the bottom of which is a flexible cover-like structure that can be deformed according to the arc structure of the upper end surface of the arc plate 80 to avoid indentations on the upper end surface of the arc plate 80 .

[0063] Since the center positions of the upper end surfaces of the arc plates 80 of different widths are different, in order to enable the position of the pressing piece 72 to be adjusted along the x-direction, further, the z-direction limiting mechanism 70 of this embodiment also includes a gantry 73 fixed to the upper end of the operating table 10, a guide rail 74 fixed to the gantry 73 and arranged along the x-direction, and a carrier plate 75 arranged on the guide rail 74 and capable of adjusting the installation position along the x-direction. The third driving device 71 is fixed to the carrier plate 75, and the position of the pressing piece 72 along the x-direction can be adjusted by adjusting the installation position of the carrier plate 75 on the guide rail 74, thereby adapting to the z-direction positioning of the arc plates 80 of different widths.
