Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Fig. 1 is a schematic structural diagram of a bezel provided in an embodiment of the present application. As shown in fig. 1, the bezel is annular, O1 is the center of the bezel, C1 is the intersection of the two oblique sides of the shield on the bezel, and C1 is commonly used to indicate the 12O 'clock position in a watch, which needs to be aligned with the 12O' clock position on the dial during fitting. The bezel is usually made by machining, generally in one piece, and is made of ceramic or metal. Because the characteristics are obvious, such as C1 point, the edge grabbing and point taking of the adhering device using the CCD (charged Coupled device) are easier, and the size control is better.
Fig. 2 is a schematic structural diagram of a dial provided in an embodiment of the present application. As shown in fig. 2, the dial includes a Touch Panel (TP) assembly and a display screen assembly, the display screen assembly includes a Liquid Crystal Module (LCM), a Light Emitting Diode (LED), and an Organic Light-Emitting Diode (OLED); the touch screen assembly is circular, shown by the outer circle in fig. 2, with the center of the circle being the position shown at point O2. The inner circle in fig. 2 is an inscribed circle of the display screen assembly, and it should be understood that, in actual production, the display screen assembly is rectangular, and in this embodiment, for convenience of understanding, the inscribed circle of the display screen assembly is shown, an X axis (an axis where O2C2 is located in the drawing) and a Y axis (an axis where C2C3 is located in the drawing) are arranged in the display screen assembly, the X axis is a central line of two opposite sides of the rectangle, the Y axis is a central line of two opposite other opposite sides of the rectangle, and an intersection point of the X axis and the Y axis is a central point of the rectangle, that is, a point C2 in fig. 2. The positive end position C3 of the Y-axis indicates the 12 o' clock position in the watch. Wherein, C2 and C3 are both displayed after the display screen component is lighted.
The dial plate is an assembly, and O2 and C2 should be overlapped theoretically, however, the common technical level of the current screen attaching industry can only achieve that the offset distance between O2 and C2 is less than or equal to 0.15mm, part of the technology can be controlled to be less than or equal to 0.10mm, the yield is low, and inconvenience is brought to the downstream whole machine assembling process.
In the process of attaching the watch ring and the watch dial, the first index parameter is satisfied, namely the Y-axis end point C3 on the watch dial is located on a connecting line O1C1 of a circle center O1 of the watch ring and a shield bevel edge intersection point C1 as far as possible, and in actual production, the control standard deviation required by the first index parameter is less than or equal to 0.08 mm. The second index parameter can be understood as making the clearance between the inner circle of the watch ring and the outer circle of the dial plate even, and the unilateral clearance is 0.075mm, namely the control standard clearance is less than or equal to 0.15 mm.
In order to achieve the two index parameters, the following two prior art schemes are generally adopted in the industry at present:
fig. 3 is a schematic diagram of a first prior art provided in an embodiment of the present application. As shown in fig. 3, selecting a circle center O1 of the inner circle of the bezel and an intersection C2 of an X axis and a Y axis in the dial plate for concentric joint; and selecting a connecting line O1C1 of a circle center O1 of the inner circle of the bezel and a bevel edge intersection C1 of the shield, and selecting a C2C3 in the dial plate to be coaxially attached.
As can be seen from the right hand side of the middle mark in fig. 3, there is an interference area 31 between the bezel and the dial and a gap area 32 between the bezel and the dial. Using the first approach, the concentricity of O1 and C2 could be controlled to be 0.05mm theoretically, and the coaxiality of O1C1 and C2C3 could be controlled to be within 0.25 °, i.e., point C3 lies on line O1C 1. However, in the actual production process, the deviation between O2 and C2 is less than or equal to 0.15mm, so that the interference area causes defects such as dial lapping (TP warping), dial edge cracking (TP cracking) and contact slip eccentricity; the gap area causes the gap exceeding standard, causes the defects of exposed substrates, unqualified waterproof and airtight performance and the like, and causes higher integral reject ratio and rejection rate which are about 5 percent.
Fig. 4 is a schematic diagram of a second prior art provided in an embodiment of the present application. As shown in fig. 4, selecting a circle center O1 of the inner circle of the bezel and a circle center O2 of the outer circle of the dial plate for concentric fitting; and selecting a connecting line O1C1 of a circle center O1 of the inner circle of the bezel and a bevel edge intersection C1 of the shield, and coaxially attaching the connecting line O1C1 to a cross line Y axis of a dial display area. As can be seen from fig. 4, with the second solution, theoretically the concentricity of O1 and O2 can be controlled within 0.05mm, and the gap between the bezel and the dial periphery is uniform; however, the coaxiality of the O1C1 and the Y axis is difficult to control at 0.25 degrees, due to the influence that the deviation of the O2 and the C2 is less than or equal to 0.15mm, the O1C1 and the Y axis C2C3 have a distance of 0.15mm before being attached, and can not be coaxial, and the point C3 is not on the O1C1, the deviation distance of the first index parameter is less than or equal to 0.08mm and can not be met, and the lightened appearance can not meet the index requirement of the appearance, so that the defect rate is about 3 percent.
To sum up, the whole yield of first kind of scheme is lower, and the disability rate is higher, and the defective rate is about 5%, and the coaxial effect can not reach to the second kind of scheme, and the defective rate is about 3%, all can't stably put into production, satisfies the high quality requirement.
In order to solve the technical problems, the technical conception process of the inventor is as follows: on the basis of concentric fitting in the second scheme, a second circle center position and a second preset position are selected, and a target rotation angle is determined, so that the dial rotates towards the direction of the first preset position by taking the second circle center position as a rotation point, and the coaxial fitting degree is improved.
The technical solution of the present application will be described in detail below with reference to specific examples. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 5 is a schematic view of a processing system for attaching a dial to a bezel according to an embodiment of the present application. The system comprises: an image acquisition device 51, a processing device 52 for attaching a dial to a bezel, and an attaching device 53; the laminating equipment comprises a mechanical arm;
the image acquisition device 51 is used for acquiring images of the bezel to obtain a first image and acquiring images of the dial to obtain a second image;
and the processing device for attaching the dial plate and the dial ring is used for determining the adjustment parameters of the dial plate according to the first image and the second image so that the dial ring and the dial plate can meet the first index parameters and the second index parameters.
And the attaching equipment is used for attaching the watch ring and the dial plate when the watch ring and the dial plate are determined to meet the first index parameter and the second index parameter.
Specifically, in the process of attaching the dial and the bezel, the dial is fixed on a workbench, the dial is adsorbed by a mechanical arm, the dial is subjected to image acquisition by an image acquisition device such as a camera, the dial is subjected to image acquisition, then according to a first image obtained by image acquisition on the dial and a second image obtained by image acquisition on the dial, the moving distance of the mechanical arm in the horizontal direction and the rotating angle of the mechanical arm in the direction of the bevel edge intersection point of the shield on the dial by taking the center of circle of the dial as a rotating point are calculated, then the computer equipment generates a control instruction according to the moving distance and the rotating angle and sends the control instruction to the mechanical arm so as to control the mechanical arm to move and rotate in the horizontal direction, so that the center of the inner circle of the dial is concentrically attached to the center of the dial, and the connecting line of the center of the circle of the dial and the bevel edge intersection point of the shield is connected to the dial, and the Y axis of the cross line of the dial display area is coaxially attached. The following will specifically describe how to determine the adjustment parameter of the dial plate according to the first image and the second image, so that the first index parameter and the second index parameter can be satisfied between the bezel and the dial plate, thereby achieving the purpose of improving the yield while satisfying the high quality requirement.
Fig. 6 is a flowchart of a processing method for attaching a dial to a bezel according to an embodiment of the present application. As shown in fig. 6, the processing method for attaching the dial plate to the bezel may include the following steps:
and step s1, acquiring a first image obtained by image acquisition of the watch bezel, and acquiring a second image obtained by image acquisition of the watch dial.
Wherein, the dial plate includes touch-sensitive screen subassembly and display screen subassembly, and the touch-sensitive screen subassembly is circular.
The execution main body of the embodiment may be a computer device, and specifically, may be a computer device carried by the attaching device itself. Such as a Programmable Logic Controller (PLC).
In this embodiment, an image acquisition device, such as a camera, acquires an image of the bezel to obtain a first image, and acquires an image of the dial to obtain a second image. The watch ring and the dial are arranged oppositely, so that when the image acquisition device acquires images of the watch ring, the lens is positioned right above the watch ring, and the images are photographed from right above the watch ring. Similarly, when the image acquisition device acquires an image of the dial, the lens should be positioned right above the dial, and a picture should be taken from right above the dial.
And step s2, determining a first circle center position and a first preset position of the bezel according to the first image.
Wherein the first predetermined position is located in an annular region of the bezel. Fig. 7 is a schematic diagram illustrating a principle that a bezel is attached to a dial according to an embodiment of the present application. As shown in the drawing shown at the upper left in fig. 7, the first center position of the bezel refers to a center O1 point of the inner circle of the bezel. The first predetermined position is the point C1 at which the two oblique sides of the shield intersect.
Specifically, the O1 point of the center of the inner circle may be determined mathematically. For example, by arbitrarily drawing two chords in the inner circle and respectively drawing the perpendicular bisectors of the two chords, the intersection point of the two perpendicular bisectors is the center of a circle. Of course, the embodiment is not limited to the above-mentioned manner for determining the first center position of the bezel, and other methods for determining the center position of a circle may be applied to the present application.
Step s3, determining a second circle center position and a second preset position of the dial plate according to the second image; the second preset position is used for indicating the position of a preset time point on the dial plate, and the first preset position is aligned with the second preset position when the dial ring is attached to the dial plate.
Since the X-axis and the Y-axis are included in the photographed second image, the end point of the forward direction of the Y-axis may be directly determined as the second preset position. Wherein the second preset position may be used to indicate the position where the 12 o' clock time is located in the dial.
Specifically, step s3 includes: determining a second circle center position of the touch screen assembly and a second preset position of the display screen assembly according to the second image; the second preset position is an end point of the Y axis and is used for indicating the position of a preset time point of the dial plate; the Y-axis is the midline of two oppositely disposed sides of the rectangular shaped display screen assembly.
Similarly, the second location of the center of the touch screen assembly may be determined with reference to the specific embodiment of determining the first location of the center of the bezel, which may be particularly referred to. This embodiment will not be described in detail here.
And step s4, determining the distance between the first circle center position and the second circle center position to obtain the target moving distance, and determining the target rotation angle according to the first preset position, the second circle center position and the second preset position.
Wherein the target moving distance comprises a moving distance of an X axis and a moving distance of a Y axis. Specifically, determining a distance between a first circle center position and a second circle center position to obtain a target moving distance includes: obtaining the moving distance of the target moving distance on the X axis according to the absolute value of the difference value of the first X axis coordinate and the second X axis coordinate; and obtaining the moving distance of the target moving distance on the Y axis according to the absolute value of the difference value of the first Y-axis coordinate and the second Y-axis coordinate.

Illustratively, the first center position may be recorded as (X1, Y1), and the second center position may be recorded as (X2, Y2), and the target moving distance is (X3, Y3), where X3 is the absolute value of the difference between X1 and X2, and Y3 is the absolute value of the difference between Y1 and Y2.

Specifically, after the bezel and the dial are concentrically attached, i.e., O1 and O2 are overlapped, the target distance from the second preset position C3 to the first axis O1C1 is determined. Illustratively, a vertical line segment perpendicular to O1C1 may be made from C3, and the length of the vertical line segment is the target distance.
And a3, determining a second axis according to the second circle center position and the second preset position.

Exemplarily, assuming that the target rotation angle is a and the target distance is d, the target rotation angle a may be obtained according to sinA = d/| O2C3 |.
On the basis of the first alternative embodiment, after step a3, the second axis may also be displayed. The second axis can be visualized by displaying the second axis so that the user can visually see the piece of virtual axis created.
