Abstract
The invention discloses a light treatment and processing method of light treatment workpieces. The invention is suitable for positioning, optical treatment and processing of small-size optical treatment workpieces, and has the advantages of less flow, convenient operation, avoidance of error problem caused by transportation and the like.
Description
Technical Field
The present invention relates to a workpiece optical processing technology, and more particularly, to an optical processing method for small-sized optical processed workpieces.
Background
The optical processing is that the equipment cuts, coats or optically reflects a given shape on a workpiece according to a specific shape by using a light beam, and the optical processing workpiece is the workpiece processed by the light beam. The workpiece is placed on the equipment to be positioned, and the position of the workpiece relative to the equipment is determined, so that the light beam can be automatically aligned to the point needing light treatment. The common positioning includes manually observing the position of a workpiece, and positioning by using a measuring instrument, such as a two-dimensional measuring instrument.
At present, for some large-sized workpieces to be processed by light, such as cover plates, specifically, common mobile phone glass cover plates, vehicle-mounted glass cover plates, etc., the sizes are large, before the light processing device performs light processing on the cover plates, if a CCD (charge coupled device) camera on the light processing device directly captures the cover plates, the contour of the whole cover plates cannot be completely and accurately captured. The grabbing is understood as obtaining the parameters of the grabbed object by using the visual detection function of the CCD.
The positioning of the existing large-size cover plate is generally realized by adopting the following steps: 1. firstly, placing the large-size cover plates on a measuring platform (such as a quadratic element platform), wherein the measuring platform is provided with mark points for being grabbed by a CCD camera, and measuring by a measuring instrument (such as a measuring instrument) to obtain the relative position relation between each large-size cover plate and the mark points (mark points); 2. then moving the large-size cover plate and the measuring carrier and placing the large-size cover plate and the measuring carrier on a working table of the optical processing equipment, and transmitting the relative position relation data between the cover plate and the mark points measured in the step 1 to a controller of the optical processing equipment; 3. the CCD camera of the optical processing equipment grabs the positions of the mark points (the mark points can be completely grabbed by the CCD camera due to small size) and transmits the positions to the controller, and the controller calculates the positions of the large-size cover plates on the working table of the optical processing equipment (namely the positions of each large-size cover plate relative to the optical processing equipment) according to the positions of the mark points and the relative position relationship between the cover plates and the mark points measured in the step 1.
However, for some light processing workpieces with relatively small sizes, such as glass cover plates of smart watches, if the positioning method is used for positioning, the operation is not very convenient due to more processes, and the implementation process is more complicated and the precision is lower due to the carrying and multiple calculation processes, particularly, errors are easily generated during the carrying.

Detailed Description
The technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.
Referring to fig. 1 to 4, a positioning method for optically processing workpieces according to the present invention includes placing a carrier 4 carrying a plurality of optically processed workpieces 5 on a work table 1 of an optical processing apparatus, and directly grabbing each optically processed workpiece 5 by a positioning apparatus 3 on the optical processing apparatus to obtain parameters of each optically processed workpiece 5.
In this embodiment, as shown in fig. 2 to 3, the light processing workpiece 5 may be a small-sized cover plate, such as a glass cover plate of a common smart watch, the size of the cover plate is small, for example, 40mm × 40mm, the outline is generally square or circular, and the cover plates are located in a graspable range of the positioning device 3 of the light processing device, so that the cover plates can be completely and accurately grasped by the positioning device 3 of the light processing device. Of course, in other embodiments, the light treatment workpiece 5 is not limited to a cover plate and the dimensions and profile shapes are not limited to those described herein, as long as objects having dimensions within the graspable range of the positioning apparatus 3 of the light treatment apparatus are applicable to the present invention.
The positioning device 3 on the optical processing device may be implemented by a CCD camera 31 or an assembly of the CCD camera 31 and an optical processing lens 32 assembled on the CCD camera 31, the CCD camera 31 has a field of view, which is a range that the CCD camera 31 can capture, the captured optical processing workpiece 5 of the present invention can be fully covered by the field of view of the CCD camera 31, so that the object can be directly and completely captured by the CCD camera 31 to obtain corresponding parameters of the object, the parameters including the position of the optical processing workpiece 5 on the work table 1, the contour of the optical processing workpiece 5, the size (such as side length, round angle, etc.), and the like. The present invention mainly acquires the position of the light processing workpiece 5 on the work table 1, thereby performing precise light processing on the light processing workpiece 5 according to the position. Of course, since the size of each of the light processing workpieces 5 has an error, the light processing parameters may be adjusted in accordance with the size of each of the light processing workpieces 5. The light processing lens 32 can enlarge the field of view of the CCD camera 31, so that the range of the size of the light processing workpiece 5 that can be positioned according to the present invention can be enlarged, and the application range of the positioning method according to the present invention can be enlarged.
Preferably, in order to avoid the CCD camera 31 from confusing a plurality of light processing workpieces 5 and causing the problem of erroneous grasping, the present invention sets the distance between two adjacent light processing workpieces 5 to be 2.5mm or more.
After the positioning device 3 of the optical processing device finishes grabbing one optical processing workpiece 5, the positioning device 3 starts to search for the next optical processing workpiece 5, and determines the grabbing position of the next optical processing workpiece 5, during the search, the optical processing device searches according to a corresponding search rule, wherein the search rule comprises a difference factor between the optical processing workpiece 5 and the carrier 4 and/or an attribute of the optical processing workpiece 5, the difference factor comprises a color difference between the optical processing workpiece 5 and the carrier 4, generally, the color difference between the optical processing workpiece 5 and the carrier 4 is large, for example, the optical processing workpiece 5 is black, and the carrier 4 is transparent; the properties of the light-treated workpiece 5 include the edges of the light-treated workpiece. Specifically, the light processing apparatus searches for a captured black color, and if it is found, captures the edge of the black light processing workpiece to determine the grasping position of the light processing workpiece 5, for example, between two adjacent light processing workpieces 5. The optical processing apparatus searches for and determines the gripping position of the optical processing workpiece 5 while moving to the gripping position so that the next optical processing workpiece 5 to be gripped is located within the gripping range of the positioning apparatus 3, thereby performing accurate gripping of the next optical processing workpiece 5. In practice, the search rule and the grasping position of the present invention are not limited to those defined above, and the present invention is applicable as long as the search rule enables the optical processing apparatus to determine the grasping position of the next optical processing workpiece 5, and as long as the grasping position enables the next optical processing workpiece 5 to be within the grasping range of the positioning apparatus 3.
The invention grabs the light processing workpieces 5 one by one, thereby enabling the positioning data of each light processing workpiece 5 to be independent and avoiding accumulative errors.
In this embodiment, as shown in fig. 6 and 9, the plurality of light processing workpieces 5 are preferably distributed on the stage 4 in a matrix form, that is, arranged in M rows and N columns, where M and N are both natural numbers greater than or equal to 1. Of course, the arrangement of the light processing workpiece 5 on the carrier 4 in the present invention is not limited.
Compared with the positioning process of the large-size optical processing workpiece, the positioning method has the advantages of less flow, convenience in operation, avoidance of error problem caused by transportation and the like because the transportation and calculation processes are omitted, and further improves the positioning accuracy.
Referring to fig. 1 and 5, a method for photo-processing a workpiece according to the present invention includes: a plurality of light processing workpieces 5 are placed on a worktable surface 1 of light processing equipment, and the light processing equipment gradually positions the light processing workpieces 5 and then carries out light processing until all the light processing workpieces 5 are subjected to light processing.
Wherein, a plurality of light processing workpieces 5 can be preferably loaded on a carrier 4, and then the carrier 4 is placed on the working table surface 1 of the light processing equipment; of course, the light source can be directly placed on the working table 1 of the light processing equipment according to a certain sequence. The placing sequence can be distributed according to the matrix form, namely M rows and N columns are arranged, and M and N are natural numbers which are more than or equal to 1.
In one embodiment, after the positioning device 3 of the optical processing device has positioned a part of the optical processing workpieces 5 on the carrier 4, the optical processing lens 2 of the optical processing device performs optical processing on the part of the optical processing workpieces 5, and while performing optical processing, the positioning device 3 of the optical processing device positions at least a part of the remaining optical processing workpieces 5, and the process is repeated until all the optical processing workpieces 5 are optically processed.
Referring to fig. 11, the positioning device 3 of the optical processing apparatus starts to position the optical processing workpieces 5, and the optical processing lens 2 is in the standby position, and when the positioning device 3 positions a predetermined number of optical processing workpieces 5, three rows of optical processing workpieces 5 on the carrier 4 are positioned, and the optical processing workpieces are stepped in the row direction after each row is positioned. In the third row, the optical processing lens 2 is still in the standby position, after the device 3 to be positioned is positioned to the fourth row of optical processing workpieces 5, and after a running space is reserved for the optical processing lens 2, the optical processing lens 2 starts optical processing work, and the positioned three rows of optical processing workpieces 5 are subjected to optical processing one by one. While the light processing lens 2 is performing light processing, the positioning device 3 of the light processing device may continue to perform light processing on the next several rows (i.e., the next several rows from the fourth row) of light processing workpieces 5. The light processing method of the invention can improve the light processing efficiency of the light processing equipment by positioning the light processing workpiece 5 at the same time of light processing.
In this embodiment, as shown in fig. 12, the positioning device 3 and the optical processing lens 2 of the optical processing device are driven by two independent driving members, respectively, and it is possible to realize independent or simultaneous positioning and optical processing of the optical processing workpiece 5.
In another alternative embodiment, the light treatment apparatus positions each light treatment workpiece 5 step by step before performing light treatment. That is, the optical processing apparatus positions each optical processing workpiece 5 and then performs optical processing on the optical processing workpiece 5, and then positions and then performs optical processing on the next optical processing workpiece 5 after the optical processing is finished, and the process is repeated.
In the above two embodiments, the process of positioning each photo-processing workpiece 5 by the photo-processing apparatus may adopt the process described in the above positioning method, and the description of the process is omitted here, and reference may be made to the above description. Of course, other positioning methods that can obtain the positioning data of each of the light-processed workpieces 5 are also applicable to the present invention.
In another alternative embodiment, as shown in fig. 1, 6 and 7, one of the implementations of the light processing process of the light processing device includes the following steps:
and S10, positioning each light processing workpiece along the light processing direction and then performing light processing until finishing the light processing of a row of light processing workpieces in the light processing direction.
Specifically, in this embodiment, the optical processing apparatus includes a table top 1, an optical processing lens 2, and a positioning apparatus 3, where the table top 1 is used to carry a stage 4, and the stage 4 is used to carry a plurality of optical processing workpieces 5 to be optically processed, and in this embodiment, the stage 4 is a general stage, that is, any stage capable of carrying the optical processing workpieces 5 is suitable for the present invention, and the optical processing workpieces 5 are arranged on the stage 4 in M rows and N columns, where the column direction is the optical processing direction or the opposite direction to the optical processing direction, and the row direction is a step direction, where the optical processing direction is the y direction shown in the figure, and the step direction is the x direction shown in the figure.
The positioning device 3 and the optical processing lens 2 are arranged above the carrier 4 through a beam frame 6 and are respectively used for positioning and optically processing the optical processing workpiece 5 on the carrier 4, and the beam frame 6 can move back and forth along the optical processing direction and the direction opposite to the optical processing direction, so that the positioning device 3 and the optical processing lens 2 on the beam frame are driven to move back and forth along the optical processing direction and the direction opposite to the optical processing direction. In practice, the positioning device 3 may be disposed on one side of the light processing lens 2 in the light processing direction, specifically, in front of the light processing lens 2, or two positioning devices 3 may be disposed on both sides of the light processing lens 2 in the light processing direction, that is, one positioning device 3 is disposed in front of and behind the light processing lens 2 in the light processing direction. The positioning device 3 may be implemented by a CCD camera 31 or an assembly of the CCD camera 31 and a light processing lens 32 assembled on the CCD camera 31, in this embodiment, the positioning device 3 is implemented by a CCD camera 31 or an assembly of the CCD camera 31 and a light processing lens 32 assembled on the CCD camera 31, and the positioning device 3 is disposed in front of the light processing lens 2 in the light processing direction.
In S10, the positioning device 3 and the optical processing lens 2 are driven by the beam mount 6 to first position and then perform optical processing on each optical processing workpiece 5 in the row of optical processing workpieces along the optical processing direction until the row of optical processing workpieces in the optical processing direction is optically processed. In the embodiment, the positioning device 3 is located in front of the optical processing lens 2 in the optical processing direction, so that when moving along the optical processing direction, the positioning device 3 and the optical processing lens 2 can position and optically process one optical processing workpiece 5 in sequence. The positioning method is a flow of the positioning method for optically processing the workpiece 5, and is not described herein again.
S20, moving in a direction approaching the next row of optically processed workpieces in a step direction perpendicular to the optical processing direction, and returning in a direction opposite to the optical processing direction, and proceeding to step S10 to optically process the next row of optically processed workpieces.
Specifically, after one row of the light processing workpieces is light-processed, the next row of the light processing workpieces continues to be light-processed, that is, the positioning device 3 and the light processing lens 2 move in a direction approaching the next row of the light processing workpieces in a stepping direction perpendicular to the light processing direction. Since the positioning device 3 is provided only on one side of the optical processing lens 2 in the present embodiment, in the opposite direction to the optical processing direction, since the positioning device 3 is located behind the optical processing lens 2 in the opposite direction to the optical processing direction due to the relative position provided between the positioning device 3 and the optical processing lens 2, that is, in the opposite direction to the optical processing direction, the optical processing workpieces in the row cannot be positioned first and then subjected to the optical processing, the present embodiment returns to the home position in the opposite direction to the optical processing direction after the positioning device 3 and the optical processing lens 2 are moved to the next row, and after the home position, the positioning and the optical processing for each optical processing workpiece 5 in the row in the optical processing direction are continued in accordance with step S10.
And S30, repeating the steps S10 and S20 until all the light processing workpieces are subjected to light processing.

The positioning device 3 and the optical processing lens 2 are arranged above the carrier 4 through a beam frame 6 and are respectively used for positioning and optically processing the optical processing workpiece 5 on the carrier 4, and the beam frame 6 can move back and forth along the optical processing direction and the direction opposite to the optical processing direction, so that the positioning device 3 and the optical processing lens 2 on the beam frame are driven to move back and forth along the optical processing direction and the direction opposite to the optical processing direction. In practice, a positioning device 3 is arranged on each side of the light processing lens 2 in the light processing direction, i.e. a positioning device 3 is arranged in front of and behind the light processing lens 2 in the light processing direction. The positioning device 3 may be implemented by a CCD camera 31 or an assembly of the CCD camera 31 and a light processing lens 32 assembled on the CCD camera 31, in this embodiment, the positioning device 3 is implemented by a CCD camera 31 or an assembly of the CCD camera 31 and a light processing lens 32 assembled on the CCD camera 31, and a positioning device 3 is respectively disposed in front of and behind the light processing lens 2 in the light processing direction.

And S200, moving to the next row of light processing workpieces along the stepping direction vertical to the light processing direction, positioning each light processing workpiece in the next row along the direction opposite to the light processing direction, and then performing light processing until the next row of light processing workpieces are subjected to light processing.
Specifically, after one row of the light processing workpieces is light-processed, the next row of the light processing workpieces continues to be light-processed, that is, the positioning device 3 and the light processing lens 2 move in a direction approaching the next row of the light processing workpieces in a stepping direction perpendicular to the light processing direction. Since the positioning device 3 is disposed in front of and behind the optical processing lens 2 in the optical processing direction in this embodiment, the positioning device 3 is disposed in front of the optical processing lens 2 in the opposite direction to the optical processing direction, and thus the optical processing workpieces 5 in the row can be positioned first and then optically processed, so that in this embodiment, after the positioning device 3 and the optical processing lens 2 are moved to the next row, each optical processing workpiece 5 in the row is positioned first and then optically processed in the optical processing direction in step S100 directly in the direction opposite to the optical processing direction.
