Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all alterations and modifications as fall within the scope of the application.
Fig. 1 and 2 are partial structural schematic views of a stylus pen, fig. 3 is an exploded view of fig. 2, and fig. 4 and 5 are structural schematic views of a pressure-sensitive support 102 in fig. 1 from different perspectives. As shown in fig. 1 to 5, the stylus pen may include a pressure-sensitive module 101, a pressure-sensitive bracket 102, a nut 103, and a cap 104, wherein the nut 103 may be screwed with the pressure-sensitive module 101, and the cap 104 is disposed at one end of the pressure-sensitive module 101. The pressure-sensitive support 102 has a first channel penetrating in the axial direction and a second channel penetrating in the radial direction, and the first channel and the second channel are communicated. The pressure-sensitive bracket 102 is sleeved on the pressure-sensitive module 101 through the first channel, the relative position between the pressure-sensitive bracket 102 and the pressure-sensitive module 101 is fixed, the nut 103 is exposed to the outside through the second channel, and the nut 103 is conveniently welded on the pressure-sensitive module 101 through the second channel.
As shown in fig. 1, 3, and 4, the pressure sensitive bracket 102 has a reference surface with reference to the inner wall surface and/or the outer wall surface. The first outer wall surface 1021 of the pressure sensitive bracket 102 close to the pen cap 104 is taken as a first reference surface, the second outer wall surface 1024 far away from the pen cap 104 is taken as a fourth reference surface, the first inner wall surface 1022 close to the pen cap 104 is taken as a second reference surface, and the third inner wall surface 1023 far away from the pen cap 104 is taken as a third reference surface. When the nut 103 comprises the first nut 1031 and the second nut 1032, the second nut 1032 is closer to the pen cap 104 relative to the first nut 1031, one side surface of the first nut 1031, which is far away from the pen cap 104, is a first positioning surface, and one side surface of the second nut 1032, which is far away from the nut 104, is a second positioning surface.
In the process of implementing the present application, the inventor finds that when the nut 103 in the stylus pen is moved to a specific position of the pressure sensing module 101, the nut is usually assisted by manual experience or distance measuring equipment to align, so as to implement the assembly of the stylus pen, but the manual experience or distance measuring equipment is inefficient and has low accuracy.
Example 1
Fig. 6 is a flowchart illustrating a process of performing nut alignment using an alignment pattern according to some embodiments of the present invention. Although the processes described below include operations that occur in a particular order, it should be clearly understood that the processes may include more or fewer operations that are performed sequentially or in parallel (e.g., using parallel processors or a multi-threaded environment). As shown in fig. 6, the method includes the following steps (S101 to S103):
s101, generating a contraposition graph in a display.
The alignment pattern may include two parallel line segments, and during alignment, the line segment near the cap mounting end of the pressure-sensitive module 101 is referred to as a first line segment, and the line segment far from the cap mounting end of the pressure-sensitive module 101 is referred to as a second line segment. The alignment pattern may be a parallelogram, and in some embodiments, the alignment pattern may be a rectangle with four interior corners being right angles.
As shown in fig. 7, which is a schematic structural diagram of the first alignment pattern 201 and the second alignment pattern 202, both the first alignment pattern 201 and the second alignment pattern 202 are rectangular. A line segment 2011 close to the pen cap mounting end in the first alignment graph 201 is a first line segment, and a line segment 2012 far away from the pen cap mounting end is a second line segment; the line 2021 of the second alignment pattern 202 close to the cap end is a first line, and the line 2022 far from the cap end is a second line.
S102, an image of the aligned handwriting pen is obtained and displayed in the display, the first line segment is aligned with the first datum plane or the second datum plane of the pressure-sensitive support in the image, and the second line segment is used for being aligned with the positioning plane of the nut in the image, so that the nut is located at the specific position of the pressure-sensitive module in the image.
When the handwriting pen needs to be assembled, the handwriting pen can be fixed on the welding equipment through the jig. The image of the stylus assembly may be transmitted to the display using the image sensor to display the image of the registered stylus in the display. As shown in fig. 2, during the assembly process of the stylus, the nut 103 needs to be positioned on the pressure-sensitive module 101, and the nut can be rotated on the pressure-sensitive module 101 by a jig. The image of the stylus may be displayed on the display using a CCD image sensor.
The position of the pressure-sensitive bracket 102 in the stylus pen is relatively fixed with the pressure-sensitive module 101. In one or more embodiments, the first line segment in the generated alignment pattern is aligned with the first reference surface or the second reference surface of the pressure-sensitive support in the image, and the second line segment in the alignment image can be aligned with the positioning surface of the nut in the image, so that the position of the nut 103 on the pressure-sensitive module 101 can be determined.
The distance between the first line segment and the second line segment is determined based on the reference plane used, so that the nut 103 can be located at the fixed position of the pressure sensing module 101. As shown in fig. 2, when the first line segment is aligned with the first reference surface 1021 of the pressure-sensitive support 102 in the image, the distance between the first line segment and the second line segment may be a distance a; when the first line segment is located on the second reference surface 1022 of the pressure-sensitive support 102 in the image, the distance between the first line segment and the second line segment may be a distance b; the sum of the distance b and the distances between the first reference surface 1021 and the second reference surface 1022 may be the distance a.
S103, an image of the aligned handwriting pen is obtained and displayed in the display, the second line segment is aligned with the third datum plane or the fourth datum plane of the pressure-sensitive support in the image, and the first line segment is used for being aligned with the positioning plane of the nut in the image, so that the nut is located at the specific position of the pressure-sensitive module in the image.
As shown in fig. 2, 4 and 5, the pressure sensitive bracket 102 may have four reference surfaces. In some embodiments, the second line segment in the generated alignment pattern may be used to align the third reference surface 1023 or the fourth reference surface 1024 of the pressure sensitive fixture 102 in the image, and the first line segment in the alignment pattern may be aligned with the positioning surface of the nut in the image, so that the position of the nut 103 on the pressure sensitive module 101 may be determined.
The distance between the first line segment and the second line segment is determined based on the reference plane used, so that the nut 103 can be located at the fixed position of the pressure sensing module 101. As shown in fig. 2, when the second line segment is aligned with the third reference surface 1023 of the pressure sensitive support 102 in the image, the distance between the first line segment and the second line segment may be a distance c; when the second line segment is aligned with the fourth reference surface 1024 of the pressure sensitive support 102 in the image, the distance between the first line segment and the second line segment may be a distance d. The sum of the distance c and the distances between the third reference surface 1023 and the fourth reference surface 1024 may be the distance d.
After the nut is positioned at a specific position of the pressure sensing module, subsequent operations can be initiated. For example, a laser welding operation may be initiated to weld the nut 103 and the pressure sensing module 101 together using a laser.
In summary, two parallel line segments are generated in the display, and the image of the aligned stylus is displayed in the display. Aligning the first line segment with a first reference surface or a second reference surface of the pressure-sensitive support in the image, and aligning the second line segment with a positioning surface of the nut, so that the nut is fixed at a specific position of the pressure-sensitive module; or align the second line segment with the third reference surface or the fourth reference surface of pressure-sensitive support in the image, first line segment is used for aligning with the locating surface of nut to fix the nut in the specific position of pressure-sensitive module, for relying on artifical experience or distance measurement equipment to assist the location of nut, the technical scheme of this application is efficient higher, the degree of accuracy is also higher.
The shape of the alignment pattern may be rectangular. In one or more embodiments, tolerance rectangles can be disposed at two ends of a line segment in the alignment pattern for alignment with the locating surface of the nut, and centers of the tolerance rectangles are located at end points of the alignment pattern. The tolerance rectangle is a tolerance zone of the nut and can be used for rechecking whether the nut is in a tolerance range after subsequent operation. The size of the tolerance rectangle can be reasonably selected according to actual conditions, and is not limited herein. As shown in FIG. 7, the first alignment graphic 201 may include a first tolerance rectangle 2013 and the second alignment graphic 202 may include a second tolerance rectangle 2023.
When the alignment graph is rectangular, the alignment graph further comprises a first line segment and a second line segment which are parallel, and a third line segment and a fourth line segment which are parallel; the distance between the first line segment and the second line segment and the distance between the third line segment and the fourth line segment can be obtained; and generating a corresponding rectangle based on the distance between the first line segment and the second line segment and the distance between the third line segment and the fourth line segment. In one or more embodiments, the distance between the first line segment and the second line segment and the distance between the third line segment and the fourth line segment may be input through the peripheral device, and a corresponding rectangle may be generated by the system as the alignment graph. In some embodiments, the distance between the first line segment and the second line segment and the distance between the third line segment and the fourth line segment preset by the system may also be directly obtained, so as to generate a corresponding rectangle as the alignment graph. It should be noted that the distance between the third line segment and the fourth line segment may be the diameter length of the nut, and may also be larger or smaller than the diameter length of the drop curtain.
After the system generates the alignment pattern, the alignment pattern may need to be moved to align the line segments in the alignment pattern with the reference plane of the pressure-sensitive support in the image. Visual exposure, etc. may be adjusted so that the image is sufficiently clear within the display interface to facilitate alignment of the alignment features with the reference plane. In one or more embodiments, the method may further include the steps of (S201 to S203):
s201, acquiring a moving command for the alignment graph.
The system can be operated by using a medium such as a mouse, a keyboard, a finger or a keyboard, and a movement command for moving the alignment pattern is applied to the system.
S202, based on the moving command, the first line segment of the alignment graph is aligned to the first reference surface or the second reference surface of the pressure sensitive support in the image.
If the distance between the first line segment and the second line segment in the alignment graph is determined based on the first reference surface, based on the moving command, moving the first line segment of the alignment graph to align with the first reference surface of the pressure sensitive support in the image; and if the distance between the first line segment and the second line segment in the alignment graph is determined based on the second reference surface, moving the first line segment of the alignment graph to be aligned with the second reference surface of the pressure sensitive support in the image based on the moving command.
And S203, aligning the second line segment of the alignment graph with the third reference surface or the fourth reference surface of the pressure sensitive support in the image based on the moving command.
If the distance between the first line segment and the second line segment in the alignment graph is determined based on the third reference surface, moving the second line segment of the alignment graph to align with the third reference surface of the pressure sensitive support in the image based on the moving command; and if the distance between the first line segment and the second line segment in the alignment graph is determined based on the fourth reference surface, moving the second line segment of the alignment graph to be aligned with the fourth reference surface of the pressure sensitive support in the image based on the moving command.
In one or more embodiments, as shown in fig. 1, 2, and 7, the nut 103 can include a first nut 1031 and a second nut 1032, and the alignment pattern can include a first alignment pattern 201 and a second alignment pattern 202. When the first nut 1031 and the second nut 1032 are positioned and welded, the first nut 1031 may be moved to a specific position and the first nut 1031 may be welded to the pressure-sensitive module 101 by laser; then, the second nut 1032 is moved to a specific position, and the second nut 1032 is welded to the pressure-sensitive module 101 by using laser.
The second line segment of the first alignment pattern 201 is aligned with the third reference surface of the pressure sensitive bracket 102 in the image, and the first line segment of the first alignment pattern 201 may be aligned with the first positioning surface of the first nut 1031 in the image. The distance of the first nut 1031 on the pressure-sensitive module 101 is controlled, so that the deformation amplitude of the elastic sheet 1011 on the pressure-sensitive module 101 can be controlled. A first line segment in the second alignment graphic 202 may be aligned with a first reference surface of the pressure sensitive support 102 in the image and a second line segment in the second alignment graphic 202 may be aligned with a second alignment surface of the second nut 1032 in the image. The distance of the second nut 1032 on the pressure-sensitive module 101 is controlled, and the installation position of the pen cap of the stylus pen can be controlled.
The first line segment of the alignment graph is aligned with the first reference surface or the second reference surface of the pressure-sensitive support in the image, and the second line segment of the alignment graph is used for being aligned with the positioning surface of the nut. The nut can be rotated through the jig to change the position of the nut on the pressure-sensitive module, namely, the position of the positioning surface can be changed by rotating the nut through the jig. In one or more embodiments, the method may further include the steps (S301 to S302) of:
s301, determining the position of the second line segment and the position of the nut positioning surface in the image.
After the first line segment is aligned with the first reference surface or the second reference surface of the pressure-sensitive support in the image, the position of the second line segment is unchanged, and the position of the nut positioning surface can be changed. And detecting the nut positioning surface in real time before the alignment of the nut positioning surface and the second line segment is not determined so as to determine the position of the nut positioning surface.
S302, if the position of the second line segment is superposed with the position of the nut positioning surface, the nut is determined to be located at the specific position of the pressure sensing module.
If the nut is moved to enable the position of the nut positioning surface to coincide with the position of the second line segment, the second line segment can be determined to be aligned with the nut positioning surface, namely the position of the nut on the pressure sensing module reaches a specific position, and the system can remind an operator through sound, pictures and texts and other forms.
The second line segment of the alignment graph is aligned with the third reference surface or the fourth reference surface of the pressure-sensitive support in the image, and the first line segment of the alignment graph is used for being aligned with the positioning surface of the nut. The nut can be rotated through the jig to change the position of the nut on the pressure-sensitive module, namely, the position of the positioning surface can be changed by rotating the nut through the jig. In one or more embodiments, the method may further include the steps of (S401 to S402):
