Description

Technical Field

[0001] The invention relates to the technical field of plate trimming, in particular to a servo profiling tracking trimming mechanism and a trimming method thereof. Background Art

[0002] Plate trimming requires processing of the plate corners. Traditional equipment requires two trimming motors. Each or four trimming motors drive the matching trimming tool to rotate, thereby trimming the front and back ends of the plate.

[0003] Chinese Patent No. 2014208553959 discloses a two-speed automatic control profiling tracking and rounding device for an edge banding machine, which specifically discloses: comprising a base, a side leaning wheel mounted on the base, a profiling motor, a rounding knife, upper and lower leaning wheels and an adjustment mechanism for adjusting the position of the profiling motor, wherein: the base comprises a motor mounting portion for mounting the motor and a side leaning wheel motor mounting portion for mounting the side leaning wheel, the side leaning wheel motor mounting portion is integrally arranged at the front end of the motor mounting portion; the side leaning wheel is fixed on the above-mentioned side leaning wheel motor mounting portion; the profiling motor is slidably mounted on the above-mentioned motor mounting portion, and a sliding mechanism is arranged on the motor mounting portion and the profiling motor; the rounding knife is mounted on the end of the profiling motor shaft and is located outside the above-mentioned side leaning wheel. Among them, the side support wheel is a component for positioning the side of the plate. The positioning effect of the side support wheel enables the filleting knife to accurately process the plate; but the side support wheel in this patent is a fixed setting, and the side support wheel cannot be positioned 360°, resulting in that the filleting equipment can only perform filleting processing on the front end or the rear end of the plate, so two sets of filleting equipment are required to complete the filleting processing of the front end and the rear end of the plate; in addition, the side support wheel is a fixed setting, so when processing the plate, the side support wheel will drag on the side of the plate, causing scratches on the side of the plate, which directly affects the production quality of the plate.

[0004] Therefore, it is necessary to further improve the existing plate trimming equipment. Summary of the invention

[0014] The trimming method of the servo profiling and tracking trimming mechanism comprises the following steps: Step 1: The plate is transported along the positive direction of the X-axis on the conveyor line, and the center of the trimming device is at the initial position; the control system detects the moving speed V1 of the plate through the encoder on the conveyor line, and the control system obtains the moving speed V1 of the plate and calculates the conveying position of the plate; when the front side of the plate exceeds the center of the trimming device by a distance d1, the X-axis drive assembly drives the trimming device to move along the positive direction of the X-axis at a moving speed V1, and the Z-axis drive assembly drives the trimming device to move downward along the Z-axis until the radial profiling wheel contacts the top front end of the plate; at this time, the center of the trimming device is at the first trimming position, and the trimming tool trims the top front end of the plate; Step 2: The X-axis driving assembly drives the trimming device to move along the positive direction of the X-axis at a moving speed of V2, V2>V1; when the center of the trimming device exceeds the front side of the plate by a distance d2, the center of the trimming device is located at the second trimming position, the X-axis driving assembly drives the trimming device to move along the positive direction of the X-axis at a moving speed of V1, the Z-axis driving assembly drives the trimming device to move downward along the Z-axis, the radial profiling wheel contacts the front side of the plate, and the trimming tool trims the front side of the plate; Step 3: When the center of the trimming device exceeds the bottom of the plate by a distance d3, the center of the trimming device is located at the third trimming position, the X-axis drive assembly drives the trimming device to move along the opposite direction of the X-axis at a moving speed V3, the radial profiling wheel contacts the front end of the bottom of the plate, and the trimming tool trims the front end of the bottom of the plate; Step 4: When the distance of the front side of the plate beyond the center of the trimming device is d4, the center of the trimming device is located at the fourth trimming position, and the trimming process of the front end of the plate 1 is completed; Step 5: The plate continues to be transported along the positive direction of the X-axis; when the center of the trimming device exceeds the rear side of the plate by a distance d5, the center of the trimming device is located at the fifth trimming position, and the X-axis drive assembly drives the trimming device to move along the reverse direction of the X-axis at a moving speed of V4, and the radial profiling wheel contacts the bottom rear end of the plate, and the trimming tool trims the bottom rear end of the plate; Step 6: When the distance of the rear side of the plate beyond the center of the trimming device is d6, the center of the trimming device is located at the sixth trimming position, the X-axis driving assembly drives the trimming device to move along the positive direction of the X-axis at a moving speed of V1, and the Z-axis driving assembly drives the trimming device to move upward along the Z-axis, the radial profiling wheel contacts the rear side of the plate, and the trimming tool trims the rear side of the plate; Step 7: When the center of the trimming device is higher than the rear end of the top of the plate by a distance d7, the center of the trimming device is located at the seventh trimming position, and the X-axis driving assembly drives the trimming device to move along the positive direction of the X-axis at a moving speed of V5, V5>V1, and the radial profiling wheel contacts the rear end of the top of the plate, and the trimming tool trims the rear end of the top of the plate; Step 8: When the center of the trimming device exceeds the rear side of the plate by a distance d8, the center of the trimming device is located at the eighth trimming position, and the Z-axis drive assembly drives the trimming device to move upward along the Z-axis to the completion position, and the radial profiling wheel and the trimming tool leave the top rear end of the plate, thereby completing the trimming process of the front and rear ends of a plate; the above steps are subsequently repeated to perform trimming on the next plate.

[0015] The length of the plate is L; When L>d4+d5, the Z-axis driving assembly drives the trimming device to move downward along the Z-axis from the fourth trimming position to the first avoidance position, and then the X-axis driving assembly drives the trimming device to move in the opposite direction of the X-axis from the first avoidance position to the second avoidance position, and then the Z-axis driving assembly drives the trimming device to move upward along the Z-axis from the second avoidance position to the fifth trimming position; When L≤d4+d5, the X-axis driving assembly drives the trimming device to move from the third trimming position to the sixth trimming position.

[0016] The beneficial effects of the present invention are as follows: The servo profiling and trimming mechanism sets the axial profiling wheel and the radial profiling wheel on the high-speed motor respectively, and the two profiling wheels cooperate with the trimming tool coaxially at different speeds, so as to effectively position the edges and corners of the front and rear ends of the plate. The axial profiling wheel and the radial profiling wheel can rotate respectively, because 360° all-round positioning can be achieved, so that the trimming processing of the four edges and corners of the front and rear ends of the plate can be completed by a high-speed motor. The servo profiling and trimming mechanism has high trimming processing efficiency, good processing quality, relatively small space occupation, and low manufacturing cost.

[0017] A Z-axis elastic buffer component and an X-axis elastic buffer component are provided between the X-axis slide and the trimming device, so that the trimming device can obtain elastic buffering when external forces act on it in the X-axis direction and the Z-axis direction, and at the same time, the axial profiling wheel can be axially close to the side of the plate, and the radial profiling wheel can be radially close to the top, end face and bottom of the plate. The trimming tool is effectively positioned relative to the plate, and the plate can be prevented from being offset relative to the trimming tool during the trimming process, thereby improving the processing accuracy.

[0018] There are more than two sets of trimming devices on the X-axis slide. Each set of trimming devices is driven to the processing position and the non-processing position by the corresponding Y-axis drive assembly, so as to switch the appropriate trimming device to trim the plate, reduce the operation of replacing the trimming tools, reduce the standby time of the equipment, improve the processing efficiency of the equipment, and reduce the labor intensity of workers.
