The cutting process S5, and assembling the cover to the head body S6.

Referring to Figures 1, 4 and 5, the step of providing a cover semi-finished product S1 comprises the following sub-steps: providing a sheet step S11, pre-cutting the sheet step S12, and forming a cover sheet semi-finished step S13.

In the step of providing the material sheet S11, the material sheet 20 is, for example, a carbon fiber sheet having a rectangular shape. Of course, the material sheet 20 may be of other materials or shapes.

Referring to FIG. 4, FIG. 5 and FIG. 6, in the pre-cutting board step S12, the material board 20 is first placed and positioned on a jig (not shown) of a press forming machine, and then passed through a stamping machine. The sheet 20 is stamped to cut the sheet 20 to form a sheet 21 to be formed. The stamped panel 21 has a main body 211 and a protruding body 212 protruding from the main body 211. The main body 211 is formed with a plurality of slits 213 spaced apart from each other.

Referring to FIG. 4, FIG. 6, and FIG. 7, in the step of forming the semi-finished product of the cover plate, the plate 21 to be formed is placed in a mold (not shown) of a thermoforming machine, and the protrusion of the plate 21 to be formed is formed. The plate body 212 is designed to fix the protruding plate body 212 in a fixed manner by, for example, clamping or snapping, so that the plate 21 to be formed can be stably positioned in the mold. Next, the formed sheet 21 is thermocompression-bonded by a mold, so that the sheet 21 to be formed is subjected to thermocompression bonding to form a cover semi-finished product 21'. The cover semi-finished product 21' has an arc-shaped plate portion 214 connected to the protruding plate body 212 in an arc shape, and a plurality of flanged plate portions 215 connected to the outer periphery of the curved plate portion 214, wherein the curved plate The portion 214 and the hemming plate portion 215 are formed by bending and pressing the main plate body 211 of the plate 21 to be formed. The cover blank 21' has an initial shape (shown in Fig. 7) formed by the projecting plate body 212, the curved plate portion 214, and the hemming plate portion 215.

As shown in FIG. 2, the head body 1 has a surrounding surrounding wall 11 having a wall portion 111 and an inner flange 112 projecting inwardly from the inner side of the wall portion 111. The inner flange 112 Along with the end face of the wall portion 111, the inner wall surface of the wall portion 111 defines a contoured region 113 that is connected to the inner flange 112. Referring to FIG. 1 , FIG. 2 , FIG. 8 and FIG. 9 , in the step of capturing the image S2 of the head body shown in FIG. 1 , the head body 1 is first placed on a bearing fixture 3 and the bearing fixture is placed. 3 is placed on the top surface of a working platform 41 of the image capturing device 4, so that the head body 1 is aligned under an image capturing device 42 of the image capturing device 4, and the image capturing device 42 is a charge coupled device (CCD) ) as an example. By carrying and fixing the head body 1 by the carrying jig 3, the surrounding wall 11 of the head body 1 can be directed upward and aligned with the image capturing device 42 to prevent a situation in which the surrounding wall 11 is skewed. Then, through a plurality of surrounding around the outer periphery of the head body 1 A light bar (not shown) illuminates the head body 1 so that the contour region 113 can be clearly contrasted with the wall portion 111 and the inner flange 112, respectively, for subsequent image taking and recognition.

Referring to FIG. 8 and FIG. 10, an image 5 of the head body 1 is captured by the image capturing device 42. After the image 5 is captured, the image capturing device 42 transmits the image 5 to a computer (not shown). Show). Since the image 5 will exhibit the structural features of the head body 1 on the two-dimensional coordinates, the computer can obtain information on the structural features of the head body 1 on the two-dimensional coordinates by this step.

Referring to FIG. 1 , FIG. 10 and FIG. 11 , the computer then performs image processing S3 on the image to convert the image 5 into a corresponding contour area 113 and has a three-dimensional contour processing path 91 (as shown in FIG. 24 ). The step of performing image processing on the image S3 includes the following sub-steps: an image processing step S31, and a combining step S32.

Referring to FIG. 11 , FIG. 12 , FIG. 13 and FIG. 14 , the image processing step S31 of the embodiment is processed by a computer through a software package. The package software is a Halcon software, but is not limited thereto. The image processing step S31 includes an identification processing step S311, a smoothing processing step S312, and a conversion step S313. In the identification processing step S311, the software package recognizes the image 5 captured by the image capturing device 42 to identify and convert a position corresponding to the contour region 113 (shown in FIG. 10) in the image 5. Initial contour 60 (as shown in Figure 13). Since the head body 1 has defects such as pits or bumps, the image 5 captured by the image capturing device 42 has a lot of noise, so the initial contour recognized and converted by the software package is obtained. Line 60 is subject to the aforementioned noise, resulting in defects in initial contour 60. Furthermore, since the package software generates distortion during the process of recognizing the image 5, it can be seen from the partial enlarged view of the initial outline 60 shown in FIG. 14 that the initial outline 60 is saw-toothed. For the foregoing two reasons, the initial contour line 60 cannot be directly used, and the smoothing processing step S312 must be further performed.

Referring to FIG. 12, FIG. 15 and FIG. 16, in the smoothing processing step S312, the package software smoothes the initial contour line 60 through a smoothing filter to modify the zigzag line into Approaching a straight line. After the smoothing process, the initial contour line 60 forms a two-dimensional outline 6. The outline 6 is composed of a plurality of first pixels P1, and each first pixel P1 has a two-dimensional coordinate (X). , Y).

The converted outline 6 is processed in the contour area 113 (shown in Figure 10).

Referring to FIG. 11, FIG. 18 and FIG. 19, the merging step S32 of the present embodiment mainly combines the two-dimensional image file 7 with a three-dimensional cover image file 8 to form a combined three-dimensional image file 9. The merging step S32 includes a matching sub-step S321, and a merging sub-step S322. The function of the three-dimensional cover image file 8 is to provide the Z-axis size information of the cover plate, and the three-dimensional cover image file 8 provides a reference basis for the design of the machine tool positioning fixture (not shown), so that the machine tool positioning treatment The size and curvature of the tool can be matched with the cover semi-finished product 21' (as shown in FIG. 7), so that the cover semi-finished product 21' can be stably positioned on the machine tool positioning fixture for the machine tool to carry out. Cutting operation of the cover semi-finished product 21'. Furthermore, the aforementioned Z-axis size information is used as the Z-axis in the merged three-dimensional image file 9, and the detailed operation mode is as follows.

Referring to FIG. 16, FIG. 20, FIG. 21 and FIG. 22, the three-dimensional cover image file 8 has a three-dimensional cover contour 81, and the cover contour 81 is composed of a plurality of second pixel points P2, and each second The pixel point P2 has a three-dimensional coordinate (x, y, z). In the matching sub-step S321, the contour line 6 is compared with the cover contour line 81 such that each second pixel point P2 is selected from the first pixel in the two-dimensional image file 7 that is closest to the two-dimensional coordinate distance. Point P1 matches. In the present embodiment, the matching sub-step S321 performs matching of the first and second pixel points P1, P2 through a mathematical calculation formula. Specifically, each of the second pixel points P2 has a three-dimensional coordinate (x, y, z), and finds two first pixels in the two-dimensional coordinates that are close to the (x, y) value of the aforementioned second pixel point P2. Point P1', P1", wherein the two-dimensional coordinate value of the first pixel point P1' is (X', Y'), and the two-dimensional coordinate value of the first pixel point P1" is (X", Y"). Then, a distance D1 between the second pixel point P2 and the first pixel point P1' can be calculated by the distance formula between the two points, and A distance D2 between the two pixel points P2 and the first pixel point P1". Subsequently, the value of the distance D1 and the distance D2 is determined to be small. If the value of the distance D1 is small, the first pixel point P1' and the first pixel are selected. The two pixel points P2 match, and if the value of the distance D2 is small, the first pixel point P1" is selected to match the second pixel point P2. In the present embodiment, the numerical value of the distance D1 is small as an example.

Referring to FIG. 18, FIG. 19, FIG. 23 and FIG. 24, in the merging sub-step S322, (X', Y') of the matched first pixel point P1' is merged with (z) of the second pixel point P2, To form a merged pixel point P3 having merged three-dimensional coordinates (X', Y', z). By repeating the operations of the foregoing matching sub-step S321 and the merging sub-step S322, each of the second pixel points P2 and the corresponding selected first pixel point P1 can be merged into one merged pixel point P3. Thereby, the plurality of merged pixel points P3 formed by the matched first and second pixel points P1, P2 constitute a contour processing path 91 of the merged three-dimensional image file 9. In short, by combining the two-dimensional coordinates (X', Y') of the two-dimensional image file 7 with the three-dimensional coordinates (x, y, z) of the three-dimensional cover image file 8, the merged three-dimensional image can be obtained. The combined three-dimensional coordinates of file 9 (X', Y', z).

Referring to FIG. 1 and FIG. 24, in the step of converting the numerical control programming language S4, the merged three-dimensional image file 9 is loaded into a conversion software of the computer, and the conversion software converts the contour processing path 91 into a numerical control programming language. The numerical control programming language is based on G code (G-code). The computer then outputs the NC programming language to a computer numerical control machine (CNC) (not shown). Next, the cover blank 21' (shown in Figure 7) can be placed and positioned on the machine tool positioning fixture of the computer numerical control machine tool.

Referring to FIG. 1 and FIG. 2, in the step of performing the cutting process S5 on the semi-finished product of the cover plate, the computer numerical control tool machine is driven to cut the semi-finished product 21' of the cover plate according to the aforementioned numerical control programming language, thereby reducing the semi-finished product of the cover plate 21 'The size of the initial shape. The cover blank 21', which has been cut and finished, forms a cover 2. At this time, the cover 2 has an outer periphery 22 having a final outer shape, the final outer shape having a size smaller than the initial outer shape of the cover semi-finished product 21', and the final outer shape of the outer peripheral edge 22 and the rod The contour area 113 of the head body 1 is identical in shape, and the contour size of the outer circumference 22 is slightly smaller than the contour size of the contour area 113, whereby the cover 2 can be assembled in the contour area 113 of the head body 1.

It should be noted that, in the step of performing the cutting process S5 on the semi-finished product of the cover plate, other processing methods for cutting the semi-finished product 21' of the cover plate according to the contour processing path 91 may be adopted, and the computer value not disclosed in the embodiment is not used. Control machine tools are limited.

Referring to Figures 1, 2 and 3, in the step of assembling the cover to the head body S6, the outer periphery 22 of the cover 2 is first aligned with the contoured region 113 of the head body 1, and then the cover 2 is oriented Moving downward, since the contour size of the outer circumference 22 is smaller than the contour size of the contour area 113, the cover 2 can be moved down into the contour area 113. When the cover 2 touches the inner flange 112, the assembly of the cover 2 is completed. Since the shape of the outer peripheral edge 22 of the cover plate 2 is formed according to the shape of the contoured region 113, and the outline size of the outer peripheral edge 22 is slightly smaller than the outline size of the contoured region 113, the outer peripheral edge 22 of the cover plate 2 after assembly is assembled. A gap 23 is formed between the contoured area 113. The width dimension of the slit 23 of the present embodiment is exemplified by equal to or less than 0.2 mm, whereby the degree of adhesion and accuracy of the cover 2 assembled to the head body 1 can be greatly improved.

Next, the glue is filled in the gap 23 between the outer periphery 22 of the cover 2 and the contoured region 113. Since the shape of the outer peripheral edge 22 of the cover plate 2 is formed according to the shape of the contoured region 113, the width of the full-circle slit 23 is substantially the same, so that the amount of glue can be accurately controlled during the filling process. Reduce the situation of overflowing glue. After the glue is cured, the cover 2 is fixedly coupled to the head body 1, and the two together constitute the golf club head 100.
