[0030] In order to better understand the working method of the embodiment of the present application, the left and right directions are parallel to the conveying direction of the wood board to be processed, that is, Figure 2 The left-right direction in the text is the x-axis direction; the front-back direction is the direction that is horizontally perpendicular to the left-right direction, that is, Figure 2 The direction perpendicular to the paper surface, and the front-to-back direction is the y-axis direction in the following text; the up-down direction is perpendicular to the left-right direction and the front-to-back direction, that is, Figure 2, and the up-down direction is referred to as the z-axis direction in the following text.

[0031] See also Figure 3 The processed wooden board is divided into a first area and a second area, the first area is the two corners 12 at the upper end of the wooden board, and the second area is the two corners 34 at the lower end of the wooden board.

[0032] See also Figure 1 The present application provides an embodiment of a servo tracking chamfering device, which includes a base 100; a first tracking mechanism 200, which is movably arranged on the base 100 to perform chamfering on a first area of ​​a wood board to be processed; a second tracking mechanism 300, which is movably arranged on the base 100 to perform chamfering on a second area of ​​the wood board to be processed; and two first servo motors 120, which are respectively used to drive the first tracking mechanism 200 and the second tracking mechanism 300 to move. By arranging the first servo motor 120 on the base 100, the rotation speed of the first servo motor 120 can be set accordingly according to the specifications of the wood board and the conveying speed of the wood board on the assembly line, that is, the sliding speed of the first tracking mechanism 200 and the second tracking mechanism 300 on the transmission mechanism 110, so as to realize the tracking processing of the wood board and improve the processing quality and production efficiency.

[0033] In a further embodiment, the first tracking mechanism 200 and the second tracking mechanism 300 both include a first mobile platform 400 and a second mobile platform 500. The first mobile platform 400 is slidably disposed on the base 100, and the second mobile platform 500 is movably disposed on the first mobile platform 400; the second mobile platform 500 is provided with a functional component 510 for chamfering the wood board to be processed. Specifically, a fixed shaft 410 may be disposed inside the first mobile platform 400, and the second mobile platform 500 may be disposed on the fixed shaft 410 through a slider 900; a screw rod may also be disposed inside the first mobile platform 400, and the second mobile platform 500 may be screwed with the screw rod, and the second mobile platform 500 may slide on the z-axis by controlling the rotation of the screw rod, but the invention is not limited thereto. Through this arrangement, the first mobile machine 400 and the second mobile machine 500 are independent of each other. When the first mobile machine 400 moves along the x-axis, the second mobile machine 500 can also move freely along the z-axis, thereby driving the functional component 510 to move freely along the z-axis, thereby improving the processing accuracy and expanding the processing range of the tracking mechanism.

[0034] In a further embodiment, the first mobile platform 400 includes a second servo motor 420, and the second servo motor 420 is used to drive the second mobile platform 500 to move up and down. In practical applications, the second servo motor 420 can not only adjust the moving speed of the second mobile platform 500 on the z-axis to track the wooden boards on the assembly line, but also can finely adjust the height of the second mobile platform 500 according to the thickness of the wooden boards to adapt to wooden boards of different specifications, since the thickness of the wooden boards is generally in mm, thereby further improving the work efficiency and processing accuracy.

[0035] See also Figure 2 The functional component 510 includes a profiling knife, a rotating motor 520, a profiling wheel 530 and a side plate 540. The profiling wheel 530 is arranged on the side plate 540. The side plate 540 is used to limit the front and rear positions of the wooden board. The profiling wheel 530 is used to limit the upper and lower positions of the wooden board. The profiling knife is installed on the rotating shaft of the rotating motor 520 and is used to chamfer the wooden board to be processed. In practical applications, the wooden board is Figure 2 In the pipeline transport from right to left, the board will first be transported to the first tracking mechanism 200, and then refer to Figure 3 The upper surface of the board, i.e., the first area, will first contact the profiling wheel 530 of the second mobile platform 500, and then move forward along the profiling wheel 530 to the first mobile platform 400. The profiling knife chamfers the two corners 12 of the first area of ​​the board as the rotating motor 520 rotates. The first function of the side support plate 540 is to fix the profiling wheel 530, and the other function is to stick to the side of the board and support the board conveyed from the assembly line, thus achieving a fixing effect. When the board enters the working range of the second tracking mechanism 300, the lower surface of the board, i.e., the second area, will contact the profiling wheel 530 on the second mobile platform 500 of the second tracking mechanism 300, and then move forward along the profiling wheel 530, and the profiling knife chamfers the two corners 34 of the second area of ​​the board as the rotating motor 520 rotates, thereby completing the processing of the entire board.

[0036] See also Figure 4, a connecting plate 560 that can move up and down is provided on the second mobile machine 500, and an elastic buffer 550 is provided between the second mobile machine 500 and the connecting plate 560; the functional component 510 is connected to the connecting plate 560. In actual applications, there are many types of wooden boards with different thickness specifications. The second servo motor 420 will control the second mobile machine 500 to slide on the z-axis at a very fast speed. The second mobile machine 500 itself also has a certain weight. The inertia generated during the movement may impact the first mobile machine 400 and cause wear. At this time, the setting of the connecting plate 560 and the elastic buffer 550 can provide a buffering effect when the second mobile machine 500 slides frequently, avoiding damage to the first mobile machine 400, while reducing the vibration of the functional component 510 on the second mobile machine 500 to avoid damage to parts. Preferably, the elastic buffer 550 is generally a spring, a gas spring or a rubber block. For example Figure 4 In the figure, the elastic buffer 550 is a spring, a mounting plate 910 is provided on the second mobile machine 500, a connecting plate 560 is slidably provided on the mounting plate 910, a first abutment plate 920 is provided on the top of the connecting plate 560, a second abutment plate 930 is provided on the mounting plate 910 just above the first abutment plate 920, a spring is provided between the first abutment plate 920 and the second abutment plate 930, and the upper and lower ends of the spring are respectively abutted against the second abutment plate 920 and the first abutment plate 930.

[0037] In a further embodiment, the functional component 510 further includes a switching cylinder 570, which is connected to the rotating motor 520 and is used to adjust the position of the rotating motor 520. In practical applications, when encountering wooden boards of different thickness specifications, the switching cylinder 570 can move the rotating motor 520, further making a fine adjustment to the working range of the profiling knife, so that the profiling knife moves forward and backward along the y-axis, further improving the processing accuracy.

[0038] In a conventional embodiment, the first servo motor 120 drives the first tracking mechanism 200 or the second tracking mechanism 300 to move through a transmission mechanism; the transmission mechanism includes a synchronous belt transmission mechanism. Since a synchronous wheel and a synchronous belt are provided, the first servo motor 120 directly drives the synchronous belt to drive the synchronous wheel to improve the transmission efficiency.

[0039] In a preferred embodiment, the first servo motor 120 drives the first tracking mechanism 200 or the second tracking mechanism 300 to move through a transmission mechanism; the screw transmission mechanism includes a guide rail 113, a nut and a transmission screw 114. In practical applications, when the first tracking mechanism 200 and the second tracking mechanism 300 slide on the transmission mechanism 110 in the x-axis, due to the inertia of the first tracking mechanism 200 and the second tracking mechanism 300, when the speed of the tracking mechanism is too fast, it will collide with the base 100, thereby affecting the control speed and causing the entire machine to shake violently. By setting a nut and a transmission screw 114 to be screwed together, the transmission screw 114 is screwed in and out of the base 100 to avoid the violent shaking caused by the excessive speed of the tracking mechanism, reduce the impact on the base 100, and make the first tracking mechanism 200 and the second moving mechanism 300 more stable when moving on the transmission mechanism, further improving safety. In the embodiment of the present application, the tracks of the first tracking mechanism 200 and the second tracking mechanism 300 are separately arranged, that is, there are two sets of guide rails 113, nuts and transmission screws 114 respectively. Through such an arrangement, the first tracking mechanism 200 and the second tracking mechanism 300 can be prevented from colliding during the sliding process.

[0040] Preferably, the second mobile platform 500 includes a slider 900 that can move forward and backward, and a cylinder 700 for driving the slider 900 to move. The functional component 510 is connected to the slider 900 and can move left and right relative to the slider 900. The slider 900 is provided with a telescopic device 600 for driving the functional component 510 to move. In practical applications, the first mobile platform 400 is slidably arranged on the guide rail 113. Since the distance of the guide rail 113 on the transmission mechanism 110 is limited, the first mobile platform 400 can only move within the range of the distance of the guide rail 113. The first mobile platform 400 is connected to the second mobile platform 500, so the distance of the functional component 510 of the second mobile platform 500 moving on the horizontal x-axis is also limited. When a connecting plate (560) is provided on the second mobile platform (500), the functional component (510) is connected to the slider (900) through the connecting plate (560), and the functional component (510) can move left and right on the connecting plate (560). Furthermore, by adding a slider 900 to the second mobile platform 500, the slider 900 is provided with a telescopic device 600 and a cylinder 700 for driving the functional component 510 to move. When the first mobile platform 400 is stationary, the telescopic device 600 can push the functional component 510 to move back and forth on the x-axis with the air pressure of the cylinder 700, which in turn increases the x-axis working range of the functional component 510, and can track the unprocessed wooden board or repeatedly process and check the corners of the wooden board, further improving the processing accuracy. At the same time, with this design, the distance of the guide rail 113 on the base 100 does not need to be set very long, which can shorten the length of the base 100 and save space.

[0041] In a further preferred embodiment, a second elastic buffer is provided at the bottom of the second tracking mechanism 300, and the second elastic buffer is connected to the first moving platform 400 of the second tracking mechanism 300. In practical applications, since the first tracking mechanism 200 processes the two corners 12 of the first area of ​​the wooden board, and the second tracking mechanism 300 processes the two corners 34 of the second area of ​​the wooden board, and the second area is located on the lower surface of the wooden board, the second moving platform 500 on the second tracking mechanism 300 will move more below the z-axis. The second moving platform 500 itself is heavy, so when sliding downward along the fixed axis 410, it may hit the transmission mechanism of the base 100, causing damage; in addition, the second moving platform 500 of the second tracking mechanism also works at a faster speed, and when it frequently moves up and down on the z-axis, it will cause shaking, affecting the processing accuracy. By providing a second elastic buffer at the bottom of the second tracking mechanism 300, the above two technical problems can be effectively solved, and the buffer protection function can be played. Preferably, the second elastic buffer can be a spring or a cylinder.

[0042] In a further embodiment, the base 100 includes a pressure regulator 800, which is disposed on the surface of the base 100. The instrument panel on the pressure regulator 800 allows the staff to visually observe the pressure changes of the cylinder 700 and the switching cylinder 570, so as to facilitate timely adjustment of the servo tracking chamfering device.

[0043] In actual application, the wooden boards will be continuously fed from the side of the first tracking mechanism 200 like the assembly line. The staff only needs to know in advance the thickness specifications of the wooden boards to be processed and the speed of the wooden boards transmitted by the assembly line, and set the appropriate speed through the first servo motor 120 and the second servo motor 420. When the wooden board passes through the first tracking mechanism 200, the second mobile machine 500 on the first tracking mechanism 200 will quickly approach the first area of ​​the wooden board, the upper surface of the wooden board will contact the profiling wheel 530, and the side of the wooden board will be close to the side support plate 540. Then the profiling knife will rotate to perform precision processing on the two corners 12 of the first area of ​​the wooden board. After the processing of the two corners 12 of the first area of ​​the wooden board is completed, the wooden board will be transmitted along the production line to the second tracking mechanism 300 to process the two corners 34 of the second area of ​​the wooden board. The whole processing process is as smooth as flowing water, with fast speed and high efficiency.

[0044] In summary, the servo tracking chamfering device provided in the embodiment of the present application includes a base 100; a first tracking mechanism 200, which is movably arranged on the base 100 to perform chamfering on the first area of ​​the wood board to be processed; a second tracking mechanism 300, which is movably arranged on the base 100 to perform chamfering on the second area of ​​the wood board to be processed; and two first servo motors 120, which are respectively used to drive the first tracking mechanism 200 and the second tracking mechanism 300 to move. Since the first servo motor 120 is provided, the x-axis moving speed of the first tracking mechanism 200 and the second tracking mechanism 300 can be accurately adjusted according to the size of the wood board and the transmission speed of the wood board of the assembly line, so as to achieve accurate processing of the wood board, thereby improving production efficiency and making the precision of the processed wood board more accurate.
