The polishing of a plate-shaped workpiece, such as a glass plate for electronic products such as a mobile phone, is mainly divided into two parts, namely polishing of a main body plane part on one part and polishing of an edge part on the other part, wherein for a curved glass plate, the polishing of the edge part comprises polishing of an edge cambered surface and polishing of a side edge. For polishing the edge cambered surface, a large-sized brush disc is adopted at present, and when the brush disc rotates, the edge of glass is ground, so that the edge of the glass plate is polished. The brush disc is soft, the rotating speed of the large brush disc is low, and the low polishing efficiency of the polishing mode is always suffered by the industry. For the polishing of the edge side, a method of stacking a plurality of glass plates and polishing the stacked glass plates by a brush barrel is adopted.
The invention provides a side polishing method and polishing equipment, which can finish polishing of an edge arc surface and a side edge at one time and solve the problem of low polishing efficiency.
The polishing equipment provided by the invention is shown in figures 1 to 5, and comprises a table top for fixing a workpiece, a driving mechanism, a control mechanism and a plurality of driving mechanisms, wherein the table top is positioned above the table top and is used for mounting a grinding head and driving the grinding head to rotate, driving the grinding head to revolve around the table top, controlling the height of the driving mechanism, and controlling the driving mechanism to drive the grinding head to rotate and drive the grinding head to revolve around the workpiece, and the driving mechanism is provided with a plurality of preset revolving heights; and under each preset revolution height, the grinding head is elastically abutted against the edge of the workpiece.
The revolution in the invention refers to that the grinding head rotates around the workpiece, the rotating path is different according to the different shapes of the workpiece, the revolution path can be preset, and the revolution path is controlled and corrected by the control mechanism.
After the glass plate is subjected to plane polishing, an ink layer is generally required to be coated on the surface of the glass plate to prevent the surface of the glass plate from being slightly scratched in transportation or subsequent processes, but the conventional edge polishing simultaneously grinds one side surface of the glass plate to easily cause massive abrasion of the ink layer, so that the ink layer on one side needs to be removed before the conventional edge polishing. The polishing method adopted by the invention only needs to grind the edge of the workpiece to be polished without contacting the upper plane and the lower plane of the workpiece, so that the plane ink layer is not worn, and the ink layer on one side surface does not need to be removed before edge polishing.
The driving mechanism comprises a beam 100 and a motor 110, the motor 110 is mounted on the beam 100, a rotating shaft 120 of the motor 110 extends out of two ends of the motor 110, and the beam 100 is perpendicular to the rotating shaft 120 of the motor 110; both ends of the rotating shaft 120 of the motor 110 are provided with mounting structures 121 for mounting the grinding heads to mount the first grinding head 200 and the second grinding head 300, respectively.
The polishing device further comprises an air floatation mechanism, and the air floatation mechanism is fixed to the cross beam 100; the air floating mechanism has a floating connection portion, and the floating connection portion is connected to the motor 110 to control the pressure between the grinding head and the workpiece.
The grinding surface of the first grinding head 200 is a conical surface or an arc surface expanding from bottom to top, and the grinding surface of the second grinding head 300 is a vertical cylindrical surface.
The polishing method of the polishing apparatus is divided into four basic steps:
step 1: securing a workpiece to the table top;
step 2: the control mechanism controls the driving mechanism to drive the first grinding head 200 to descend to a preset revolution height;
and step 3: the control mechanism controls the driving mechanism to drive the first grinding head 200 to rotate and drive the first grinding head 200 to revolve around the workpiece;
and 4, step 4: replacing the workpiece;
wherein the control mechanism has a plurality of preset revolution heights.
For a workpiece requiring both edge arc surface polishing and side edge polishing, the polishing process is divided into two steps, and the grinding heads are also divided into two types, the first grinding head 200 is used for polishing the edge arc surface, and the second grinding head 300 is used for polishing the side edge, for example, the control mechanism can first control the driving mechanism to drive the first grinding head 200 to polish the edge arc surface, then control the driving mechanism to drive the second grinding head 300 to polish the side edge, after the arc surface and the side edge are polished, the polishing of the workpiece is completed, the polished workpiece is taken down, and a new workpiece to be polished is replaced.
In an embodiment where both edge contour polishing and side edge polishing are desired,
the method also comprises the following steps between the basic step 3 and the basic step 4:
step 3.1: the control mechanism controls the driving mechanism to overturn and rotates the second grinding head 300 to a polishing station;
step 3.2: the control mechanism controls the driving mechanism to drive the second grinding head 300 to descend to a preset revolution height;
step 3.3: the control mechanism controls the driving mechanism to drive the second grinding head 300 to rotate and drive the second grinding head 300 to revolve around the workpiece.
Wherein, between step 2 and step 3, or between step 3.2 and step 3.3,
step a: the control mechanism controls the driving mechanism to approach the workpiece.
Specifically, the polishing surface of the first grinding wheel head 200 is an inclined conical surface or a curved surface, and when the drive mechanism drives the first grinding wheel head 200 to be pressed down, the polishing surface thereof elastically abuts against the curved surface of the edge of the workpiece. The polishing surface of the second grinding head 300 is a cylindrical surface, and after the driving mechanism drives the second grinding head 300 to press down, the second grinding head 300 is driven to approach the workpiece, so that the second grinding head can be elastically abutted against the side edge of the workpiece. The first grinding head 200 and the second grinding head 300 are positioned on different sides of the beam 100, and after the first grinding head 200 finishes polishing operation, the control mechanism controls the beam 100 to rotate so as to turn over the driving mechanism and rotate the second grinding head 300 to a polishing station; then, the control mechanism controls the driving mechanism to drive the second grinding head 300 to descend to a preset revolution height; the control mechanism controls the second grinding head 300 to approach the workpiece, and the control mechanism controls the driving mechanism to drive the second grinding head 300 to rotate and drive the second grinding head 300 to revolve around the workpiece, so that the side edge of the workpiece is polished.
In other embodiments, the polishing sequence of the edge cambered surface and the side edge can be changed, and the invention does not limit the polishing sequence of the edge cambered surface and the side edge.
The polishing method provided by the invention has the advantages that the contact surface between the grinding head and the workpiece is small, the pressure intensity is larger, and the polishing can be quickly finished. In addition, in the process of polishing a workpiece by the grinding head in a rotating manner, abrasion and deformation are inevitably generated, so that in order to prolong the service life of the grinding head, the grinding surface of the grinding head is fully utilized in a manner of fixing the workpiece and changing the position of the grinding head step by step, which is actually equivalent to dividing the grinding surface into a plurality of polishing areas 400, after the grinding skin of each polishing area 400 is abraded to a certain degree, the grinding position of the grinding head is changed, so that the next polishing area 400 is in contact with the workpiece, and each polishing area 400 corresponds to a preset revolution height.
For workpieces which are difficult to grind, when a plurality of polishing regions 400 are needed for polishing each workpiece, the method also comprises the following steps between the step 3 and the step 4:
step 3a: the control mechanism controls the driving mechanism to drive the first grinding head 200 to descend to another preset revolution height;
and step 3b: the control mechanism controls the driving mechanism to drive the first grinding head 200 to rotate and drive the first grinding head 200 to revolve around the workpiece.
For a workpiece that is relatively easy to polish, each polishing region 400 can be used to polish multiple workpieces, and the control mechanism controls the drive mechanism to descend to the next preset revolution height every a times of workpiece replacement, and the control mechanism controls the drive mechanism to descend to the last preset revolution height and to replace the grinding head after a times of workpiece replacement at the preset revolution height. Wherein A is more than or equal to 1 and less than or equal to 15. The grinding head is relatively soft in material, deformation and abrasion of the grinding head can be accumulated in the polishing process, and in order to prevent the reduction of the polishing effect caused by deformation or the deformation of the unused polishing area 400, the upper limit of the workpiece polished by the same polishing area 400 is set to 15, namely, after the polishing area 400 finishes polishing for 15 times at most, the polishing area 400 is not used for polishing no matter how the buffing loss condition is, the polishing area 400 is not used.
When the driving mechanism works at the same preset revolution height, the control mechanism controls the driving mechanism to approach the workpiece for a preset distance so as to reduce the revolution radius of the driving mechanism by the preset distance. The predetermined distance may vary depending on the particular buffing used with the buffing head. The revolution orbit of the driving mechanism for driving the grinding head to revolve is determined according to the shape of the workpiece, and the specific numerical value of the revolution radius expansion or reduction is the distance between the front revolution orbit and the rear revolution orbit.
In addition, because the grinding head is made of flexible material, the deformation of the working area can more or less affect the unused polishing area 400 in the process of grinding and polishing, therefore, the difference between the height of the B +1 th preset revolution height and the height of the B-1 th preset revolution height is set to be 2 to 8 times of the difference between the height of the B-1 th preset revolution height and the height of the B-1 th preset revolution height, wherein B is more than or equal to 4 and less than or equal to 8. That is, after B polishing zones 400 are consecutively used, the distance of the next polishing zone 400 from the B-th polishing zone 400 becomes 2 to 8 times the normal value, and then returns to the normal value, the specific times being different depending on the material used for the grinding head.
In order to ensure that the same size grinding head can provide the most polishing areas 400, the method of the invention performs one correction after using a plurality of polishing areas 400, and ensures that the deformation amount of the polishing areas 400 is within an acceptable range. In a specific embodiment, correction is performed every B + -1 revolution heights, namely when the revolution height is C, D, E, respectively, wherein 2B-2 < C < 2B +2,3B-3 < D < 3B +3,4B-4 < E < 4B +4. That is, the difference between the height of the C +1 th predetermined revolution height and the height of the C-1 th predetermined revolution height is 2 to 8 times the difference between the height of the C-1 th predetermined revolution height and the height of the D +1 th predetermined revolution height, the difference between the height of the D +1 th predetermined revolution height and the height of the D-1 th predetermined revolution height is 2 to 8 times the difference between the height of the D-1 th predetermined revolution height and the height of the E-1 th predetermined revolution height, and the difference between the height of the E +1 th predetermined revolution height and the height of the E-1 th predetermined revolution height is 2 to 8 times the difference between the height of the E-1 th predetermined revolution height and the height of the E-1 th predetermined revolution height.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
