The method for manually removing burrs is used for products with small applicable burrs and simple product structures. The grinding and removing are to use the grinding agent and the roller to vibrate to remove the burr flash. The grinding removal is suitable for small products with large batch and low required precision, but is not suitable for 3C products with high precision requirement and good consistency.

Specifically, referring to fig. 4, fig. 4 is a partial schematic view of a burr flash of a workpiece. Fig. 4 shows the profile of the burr flash at 1. Referring to fig. 5, fig. 5 is a schematic diagram of a burr flash profile of a workpiece, and fig. 5 shows a profile 1 of the burr flash. When the similarity between the image data of the workpiece and the preset burr flash template is greater than or equal to a preset threshold value, determining the burr flash on the workpiece corresponding to the image data as a target burr flash, wherein the target burr flash is a burr flash which can generate adverse effects on many aspects of the processing precision, the assembly precision, the reprocessing positioning, the appearance quality and the like of the workpiece, and is the burr flash to be removed. Therefore, it is desirable to extract the information of the burr flash in the image data, including but not limited to the information of the contour, size, area, etc.
Step S80: and controlling a laser to output a laser beam to mark a burr burring area of the workpiece according to the burr burring information, so that the burr burring on the workpiece is melted to form a smooth surface layer.
Specifically, the last laser instrument that has of controlgear, controlgear need according to the burr and drape over one's shoulders the profile of cutting over one's shoulders the front of a knife or a sword, size, information determination laser beam's such as area target marking region, mark route etc. of area after extracting the burr and drape over one's front of a knife or a sword, and the staff can input correct laser marking parameter in controlgear simultaneously, and laser marking parameter includes: power, speed, frequency, pulse width, etc. The power of the laser may be 100w, the speed may be 2000mm/s, the frequency may be 30kHz, and the pulse width may be 100 ms. After determining data such as a target marking area, a marking path and the like of a laser beam according to information such as the contour, the size, the area and the like of the burr flash, the control equipment can generate a vibrating mirror swinging signal according to the information such as the target marking area, the marking path, the laser marking parameters and the like, control the vibrating mirror in the laser to swing through the vibrating mirror swinging signal, control the laser to output a laser beam to mark the burr flash of the workpiece, enable the burr flash on the workpiece to be melted or evaporated, and form a smooth surface layer.
In the embodiment, workpiece image data is acquired; matching the workpiece image data with a preset burr flash template to obtain the similarity between the workpiece image data and the preset burr flash template; if the similarity is larger than or equal to a preset threshold value, extracting burr flash information in the workpiece image data; and controlling a laser to output a laser beam to mark a burr burring area of the workpiece according to the burr burring information, so that the burr burring on the workpiece is melted to form a smooth surface layer. According to the invention, the marking work of the laser on the workpiece is controlled through the similarity, and the laser marking work is carried out only when the similarity is greater than or equal to the preset threshold, so that the burr flash is accurately removed, the burr flash with smaller similarity is prevented from being marked, the smoothness of the surface of the workpiece is influenced, meanwhile, the manual operation is reduced, and the working efficiency and the yield of the burr flash removal are improved.
Further, a second embodiment of the laser deburring method of the present invention is provided based on the embodiment shown in fig. 1, and referring to fig. 6, fig. 6 is a flowchart illustrating the second embodiment of the laser deburring method of the present invention.
Before the acquiring the workpiece image data, the method further comprises:
step S10: acquiring contour information of a workpiece;
specifically, when the burr of the workpiece is removed, information of the workpiece is required to be input into the control device, and the control device can extract the size and the outline information of the workpiece in the information, or the control device scans the workpiece in a scanning mode and the like to obtain the size and the outline information of the workpiece.
Step S12: generating X-axis and Y-axis running tracks according to the contour information of the workpiece;
specifically, the control device is provided with a gantry structure which comprises an X axis and a Y axis, and can plan the moving tracks of the X axis and the Y axis according to the contour information of the workpiece, wherein the moving tracks comprise a moving direction and a moving distance. The range of the travel track is the range of the workpiece profile.
Step S14: and controlling the X axis and the Y axis to move according to the running track so as to drive a visual camera to acquire the workpiece image data.
Specifically, referring to fig. 7, fig. 7 is a partially enlarged schematic view of a burr flash of a workpiece. The gantry structure is also provided with image acquisition equipment, the image acquisition equipment can be a visual camera, and the image acquisition range of the visual camera is smaller than 5 multiplied by 5mm, so that the image acquisition range of the visual camera also needs to be considered when the control equipment plans the moving tracks of an X axis and a Y axis, and the phenomenon that the determination of similarity is influenced due to the fact that the image data of a plurality of workpieces acquired by the visual camera are overlapped is avoided. The motion state of the visual camera is consistent with the motion states of the X axis and the Y axis, when the X axis and the Y axis move along the moving track, the visual camera can be driven to collect workpiece image data of different areas of the workpiece according to the moving track, and the image data of the different areas form the whole image data of the workpiece together.
It should be noted that, because there is laser output to mark the burr of the workpiece when the X-axis and the Y-axis move, in order to avoid the mutual interference between the movement of the X-axis and the Y-axis and the marking of the laser output laser beam, the movement speed of the X-axis and the Y-axis needs to be much less than the speed of the laser. When the movement speeds of the X axis and the Y axis are far smaller than the speed of the laser, enough time can be reserved for the control equipment to process the workpiece image data in the movement process of the X axis and the Y axis, and meanwhile, the laser can output laser conveniently to mark burrs of the workpiece corresponding to the current workpiece image data. Thus, the X-axis and Y-axis motion speeds may be 100 mm/s.
In the embodiment, the contour information of the workpiece is obtained; generating X-axis and Y-axis running tracks according to the contour information of the workpiece; and controlling the X axis and the Y axis to move according to the running track so as to drive a visual camera to acquire the workpiece image data. The method and the device have the advantages that the workpiece images of the whole workpiece are acquired, meanwhile, the data of a plurality of workpiece images are prevented from being overlapped, the mutual interference of the movement of an X axis and a Y axis and the marking of a laser output laser beam is avoided, and the accuracy of deburring is improved.
Further, based on the embodiment shown in fig. 1, a third embodiment of the laser deburring method of the present invention is provided. After the image data is matched with a preset burr flash template and the similarity between the image data and the preset burr flash template is obtained, the method further comprises the following steps:
step S42: and if the similarity is smaller than a preset threshold value, the laser is forbidden to output the laser beam.
Specifically, if the similarity between the image data and the preset burr flash template is smaller than a preset threshold, that is, the similarity is smaller than 75%, the burr flash corresponding to the current workpiece image data has little or negligible influence on the processing precision, the assembly precision, the reprocessing positioning, the appearance quality and other aspects of the workpiece, so that the laser output laser beam needs to be prohibited from marking the burr flash corresponding to the current workpiece image data, and if the marking is performed, the surface layer of the workpiece is damaged, and the quality of the workpiece is affected.
In this embodiment, if the similarity is smaller than a preset threshold, the laser is prohibited from outputting the laser beam. The damage to the surface layer of the workpiece caused by marking of the laser beam output by the laser of the burr flash with the similarity smaller than the preset threshold is avoided, and the burr flash can be removed accurately.
Further, based on the embodiment shown in fig. 5, a fourth embodiment of the laser deburring method of the present invention is provided. After the image data of the workpiece is matched with a preset burr flash template and the similarity between the image data and the preset burr flash template is obtained, the method further comprises the following steps:
step S44: and if the similarity is smaller than a preset threshold value and the similarity is smaller than 75%, controlling the X axis and the Y axis to continue moving according to the running track so as to drive the visual camera to acquire the next frame of workpiece image data of the workpiece.
Specifically, when the similarity between the workpiece image data and the preset burr flash template is smaller than a preset threshold value, namely the similarity is smaller than 75%, the X axis and the Y axis need to be controlled to continue to move along the running track, and the visual camera is driven to continue to acquire the next frame of workpiece image data of the workpiece. And the next frame of workpiece image data is transmitted to the control equipment, so that the control equipment can process the image data in time conveniently.
In this embodiment, if the similarity is smaller than a preset threshold, the X axis and the Y axis are controlled to continue to move according to the running track, so as to drive the visual camera to acquire the next frame of workpiece image data of the workpiece. The X-axis and Y-axis continuous motion is realized, the image acquisition efficiency is improved, and the burr flash work efficiency of the workpiece is further improved.
Further, based on the embodiment shown in fig. 5, a fifth embodiment of the laser deburring method of the present invention is provided. If the similarity is greater than or equal to a preset threshold, after the burr flashing information in the image data is extracted, the method further comprises:
step S62: judging whether the marking area of the laser is larger than or equal to a burr flash area;
specifically, the field lens of the laser has a limited fixed focal length (the focal length refers to the distance from the optical lens to the marking workpiece), that is, the focal length region is the marking region of the laser. In this embodiment, the marking range of the laser is 100 × 100 mm. For a workpiece with a relatively large size, when the X-axis and the Y-axis move to drive the visual camera to continuously acquire the image data of the workpiece, the control device can determine a position area corresponding to a burr flash corresponding to the image data of the workpiece, wherein the position area is a burr flash area. The control equipment can judge whether the marking area of the current laser is larger than or equal to the burr flashing area corresponding to the workpiece image data.
Step S64: and if the marking area is larger than or equal to the burr flashing area, controlling the X axis and the Y axis to move along the running track so as to drive the visual camera to acquire the next frame of workpiece image data of the workpiece.
Specifically, if the marking area is greater than or equal to the burr flashing area, that is, the burr flashing position corresponding to the workpiece image data is in the marking area of the laser, the control device can control the X-axis and the Y-axis to move continuously along the moving track, so as to drive the visual camera to continuously acquire the next frame of workpiece image data of the workpiece.
Further, after determining whether the marking area of the laser is greater than or equal to the burr flash area, the method further includes:
step S66: and if the marking area is smaller than the burr burring area, controlling the X axis and the Y axis to be fixed at the current position.
Specifically, if the marking area is smaller than the burr flashing area, that is, the corresponding burr flashing part of the workpiece image data is not located in the marking area of the laser, the control device can control the X-axis and the Y-axis to be fixed at the current position and keep the fixed state. And meanwhile, the visual camera is fixed at the current position, and the acquisition of the image data of the workpiece outside the marking area is stopped.
Furthermore, after controlling the laser to output a laser beam to mark a burr flashing region of the workpiece according to the burr flashing information to melt the burr flashing on the workpiece and form a smooth surface layer, the method further comprises:
step S82: and controlling the X axis and the Y axis to continuously move from the current position along the running track so as to drive the visual camera to acquire the next frame of workpiece image data of the workpiece.
Specifically, the laser is connected with the gantry structure, and when the X axis and the Y axis move, the laser is driven to change the position along with the movement of the X axis and the Y axis. If the part corresponding to the burr flash in the workpiece image data is not in the marking area of the laser, namely, if part is in the marking area of the laser, the laser is controlled to output laser beams to mark the burr flash, so that the burr flash on the workpiece is melted to form a smooth surface layer. After the part of the current workpiece image data corresponding to the burr flash is melted to form a smooth surface layer, the X-axis and the Y-axis can be controlled to continue moving from the current position so as to drive the visual camera to acquire the next frame of workpiece image data of the workpiece and drive the laser to move, so that the burr flash corresponding to the next frame of image data is positioned in the marking area of the laser.
In the embodiment, whether the marking area of the laser is larger than or equal to the burr flash area is judged; and if the marking area is larger than or equal to the burr flashing area, controlling the X axis and the Y axis to move along the running track so as to drive the visual camera to acquire the next frame of workpiece image data of the workpiece. And if the marking area is smaller than the burr burring area, controlling the X axis and the Y axis to be fixed at the current position. And controlling a laser to output a laser beam to mark a burr burring area of the workpiece according to the burr burring information so as to melt the burr burring on the workpiece and form a smooth surface layer, and then controlling the X axis and the Y axis to continue moving along the running track from the current position so as to drive the visual camera to acquire the next frame of workpiece image data of the workpiece. The marking of burr flash outside the marking area of the laser is avoided, and the accuracy of burr flash removal is improved.
