Description

Technical Field

[0001] The present invention relates to a golf ball exterior processing machine, and particularly to a golf ball trimming machine with a flaw detection function. Background Art

[0002] With the improvement of people's living standards and the emphasis on outdoor leisure life, more and more people are fond of playing golf. These people may be men or women from various industries or age groups. That is to say, the golf sport allows people from different industries, age groups and genders to compete and communicate on the same field, which is exactly the charm of this sport.

[0003] In the production process of golf balls, the ball shell is formed by injection molding with an upper mold and a lower mold. Therefore, a convex mold joint line will be formed on the outer surface of the ball, and this mold joint line must be processed and removed before the surface of the ball is painted. However, as consumers' requirements for product quality become more and more strict, if only relying on manual inspection of the flaws on the ball, there may be problems such as inconsistent inspection standards, long inspection time, and difficulty in detecting flaws. Although there are already automated inspection devices on the market that capture the images of the objects to be detected and analyze them to find flaws, such inspection devices cannot continuously monitor a large number of processed balls and immediately exclude defective products without affecting production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a golf ball trimming machine with a flaw detection function in view of the deficiencies of the prior art, which can detect the defects on the ball in real time and identify the types of defects.

The rotating member is configured to perform a rotating operation to drive the holder to sequentially pass through a plurality of the workstations along a conveying path, and the holder is configured to hold the sphere and drive it to rotate.

[0010] In an embodiment of the present invention, at the inspection station, the holder drives the sphere to rotate relative to the image capture device, so that the plurality of the sphere images are captured by the image capture device at different rotation angles of the sphere.

[0011] In an embodiment of the present invention, the defect inspection system includes a light source, and the light source is configured to irradiate the sphere.

[0012] In an embodiment of the present invention, the plurality of workstations include a preparation station, and the preparation station is provided with a position detector for detecting whether the mold joint line is at a predetermined processing position before the sphere enters the trimming station.

[0013] In an embodiment of the present invention, the position detector has a notch, the position of the notch corresponding to the predetermined machining position, and the position detector is arranged such that the notch approaches in the direction of the sphere.

Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. Additionally, the drawings of the present invention are only simple schematic illustrations and are not drawn according to actual dimensions, which is stated in advance. The following implementation manners will further elaborate on the related technical content of the present invention, but the disclosed content is not intended to limit the protection scope of the present invention. In addition, the term "or" used herein should, depending on the actual situation, possibly include any one or a combination of more of the related listed items.

[0026] Unless otherwise defined, the terms used herein have the same meaning as commonly understood by those skilled in the art. The materials involved in each embodiment are commercially available or materials prepared according to the prior art if not otherwise specified. The operations or instruments involved in each embodiment are conventional operations or instruments in the art if not otherwise specified.

[0027] In view of the fact that consumers have increasingly strict requirements for product quality, and the standards of inspection quality control personnel are inconsistent and the inspection time consumed is relatively long, the present invention puts forward a new concept: after the sphere is processed, multiple images of the sphere (preferably images of the sphere at different rotation angles) are captured and analyzed to determine whether there are processing defects on the sphere that may cause poor appearance or performance degradation of the finished product.

[0028] Please refer to Figure 1 and in conjunction with Figure 2 and Figure 3As shown, an embodiment of the present invention provides a golf ball trimming machine 1 with a flaw detection function that embodies the above inventive concept, which can remove the protruding mold joint line 201 formed on the outer surface 200 of the sphere 2 due to the injection molding of the spherical shell 21. The golf ball trimming machine 1 with a flaw detection function of the present invention includes a conveying device 11 and a plurality of workstations. The conveying device 11 is arranged to drive the sphere 2 to sequentially pass through a plurality of workstations. The plurality of workstations mainly include a trimming station 12, at least one grinding station ( Figure 1 the first grinding station 13 and the second grinding station 14 shown in

[0029] In the present invention, the trimming station 12 is arranged to perform a cutting process on the mold joint line 201 of the sphere 2 to remove the mold joint line 201, and at the same time form a trimming line 202 on the outer surface 200. At least one grinding station ( Figure 1 the first grinding station 13 and the second grinding station 14 shown in

[0030] is arranged to perform a grinding process on the trimming line 202 of the sphere 2 that has undergone the cutting process to eliminate the negative impacts caused by the unqualified width of the trimming line 202, such as negative impacts on the flight performance after hitting the ball, the performance of the ball rolling on the ground after landing, and the aesthetics of the sphere. The inspection station 15 is arranged to capture a plurality of images of the sphere 2 that has undergone the grinding process and determine whether there are defects on the sphere 2 based on the images, such as the trimming line not meeting the requirements, or there being a damaged area or a dirty area on the outer surface 200 (for example, in the width range covering the trimming line 202 and the two rows of ball sockets above and below it). The main arrangements or configurations of each workstation will be further described below. Figures 4 to 8 As shown in

[0031] As Figure 4As shown, the trimming station 12 is provided with a cutting tool 121 for cutting treatment, which is mounted on a tool fixing seat 122. During use, the holder 112 drives the sphere 2 to rotate relative to the cutting tool 121, so that the mold joint line 201 repeatedly contacts the cutting tool 121 and is cut off, and a trimming line 202 is formed at the position where the mold joint line 201 originally existed. In an embodiment not shown, an adjustment mechanism is provided between the cutting tool 121 and the tool fixing seat 122, and under the action of the adjustment mechanism, the cutting tool 121 can be advanced, retracted, and the cutting angle can be changed.

[0032] As Figure 1 and Figure 5 shown, the golf ball trimming machine 1 with a defect detection function of the present invention includes a first grinding station 13 and a second grinding station 14. That is, the cut sphere 2 will be first sent to the first grinding station 13 for the first grinding, and after completion, it will be sent to the second grinding station 14 for the second grinding. In the present invention, the first grinding station 13 is arranged to perform the first grinding treatment on the trimming line 202 of the sphere 2 by using a grinding belt 131 (such as a sand cloth belt), and the second grinding station 14 is arranged to perform the second grinding treatment on the trimming line 202 of the sphere 2 by using another grinding belt 141 (such as another sand cloth belt); the first grinding treatment and the second grinding treatment can adopt the same or different grinding conditions, such as the type of grinding cloth, grinding load, rotation speed, grinding time, etc. In actual application, the grinding belts 131, 141 can be connected in cooperation with the roller groups 132, 142, and the roller groups 132, 142 are at least composed of a driving wheel and a guiding wheel to transmit the rotational power generated by a driving device (not shown in the figure) to the grinding belts 131, 141, so that the grinding belts 131, 141 operate and contact the trimming line 202 of the sphere 2 for grinding.

[0033] As Figure 6 shown, the inspection station 15 is provided with a defect inspection system 15s, and the defect inspection system 15s mainly includes an image capture device 151 and a data processing device 152 electrically connected to the image capture device 151. During use, the image capture device 151 is arranged to capture a plurality of sphere images of the ground sphere 2, and the data processing device 152 is arranged to judge whether there are defects on the sphere 2 according to the plurality of sphere images.

[0034] Furthermore, at the inspection station 15, the holder 112 drives the sphere 2 to rotate relative to the image capture device 151, and the image capture device 151 can capture the images of the sphere at different rotation angles. Additionally, after analyzing the sphere images, the data processing device 152 can obtain an average width value of the trimming line 202, which is calculated by averaging the width values of the trimming line 202 corresponding to each of multiple sphere images (sphere images at different rotation angles). The data processing device 152 further determines whether this average width value exceeds a predetermined range. If the average width value exceeds the predetermined range, it is determined that there is a defect on the sphere 2. In actual application, the image capture device 151 and the data processing device 152 can be connected through wired or wireless communication. The data processing device 152 can be a computer device, which can include a judgment module M, and the judgment module M can execute a defect judgment algorithm to determine whether the width of the trimming line 202 meets the requirements based on the measurement results on the sphere image.

[0035] In the present invention, the data processing device 152 can also determine whether the outer surface 200 of the sphere 2 (for example, in the width range covering the trimming line 202 and two rows of ball sockets above and below it) has a damaged area or a dirty area. If the outer surface 200 of the sphere 2 has a damaged area or a dirty area, it is determined that there is a defect on the sphere 2. In actual application, the judgment module M can execute a defect judgment algorithm to identify the damaged area or the dirty area on the outer surface 200 of the sphere 2 based on the features of the sphere image (such as grayscale value, area size, etc.).

[0036] The present invention can integrate the technical content related to the inspection station 15 into actual applications. Furthermore, as Figure 1 , Figure 6 and Figure 7 shown, the golf ball trimming machine 1 with a flaw detection function of the present invention includes a ball discharging mechanism 16, which is operatively connected to the conveying device 11, and includes a good product track 161, a defective product track 162, and a conversion controller 163 disposed between the good product track 161 and the defective product track 162. In actual application, the conversion controller 163 is set to: control the opening of the good product track 161 when the data processing device 152 determines that there is no defect on the sphere 2, so that the sphere 2 is discharged from the good product track 161, or control the opening of the defective product track 162 when the data processing device 152 determines that there is a defect on the sphere 2, so that the sphere 2 is discharged from the defective product track 162. The sphere 2 discharged from the good product track 161 can be further sent to a coating machine for surface coating, and the sphere 2 discharged from the defective product track 162 can be recycled and reused, such as recycling the valuable substances therein and remanufacturing.

[0037] In addition, when the data processing device 152 determines that the type of defect existing on the sphere 2 is that the trimming line 202 does not meet the requirements, the machine can be temporarily stopped 4 and the control parameters of the cutting process can be adjusted, such as the feed rate of the cutting tool 121, the cutting depth or the cutting angle, the rotation speed of the sphere 2, etc.

[0038] In practical applications, the data processing device 152 may include a display D for displaying the real-time image and inspection results (such as the number and type of defects) after the sphere 2 is processed, production information, alarm information about continuous defects of the sphere, etc. On this basis, in the future, big data analysis can be used to find out the potential causes of product defects and summarize the typical patterns of product defects.

[0039] Refer back to Figure 1 , and in cooperation with Figure 8 As shown, according to actual needs, the golf ball trimming machine 1 with a defect detection function of the present invention may further have a preparation station 17, in which a position detector 171 is provided for detecting whether the mold joint line 201 is at a predetermined processing position (the height position where the cutting tool 121 is located) before the sphere 2 enters the trimming station 12. The position detector 171 has a notch 171n, and the position of the notch 171n corresponds to the predetermined processing position of the trimming station 12. In use, the position detector 171 is arranged so that its notch 171n approaches the sphere 2. If the notch 171n can accommodate the mold joint line 201 therein, it can be determined that the mold joint line 201 is at the predetermined processing position. In addition, when the mold joint line 201 is within the notch 171n of the position detector 171, the conveying device 11 performs a rotation operation to convey the sphere 2 to the trimming station 12.
