Description

Technical Field

[0001] This invention relates to the field of industrial vision sorting technology, and more specifically, to an automatic golf ball sorting device. Background Technology

[0002] In the industrial production line of golf balls, especially in the precision manufacturing process where a high degree of surface finish is required, the inspection and sorting of finished products are crucial. Current inspection scenarios go beyond simply finding "bad balls" caused by the manufacturing process; they also face the complex problem of "distinguishing between surface cleanliness and defects," requiring the precise differentiation between "removable temporary defects" and "permanent manufacturing defects." However, in actual production environments, golf balls are highly susceptible to external contamination. This is mainly because golf balls are mostly made of high-molecular-weight polymer materials, and during processes such as belt conveying and mechanical tumbling, friction easily generates static electricity on the ball's surface, attracting large particles of dust, hair, and other impurities that can be detected by visual inspection equipment, forming unavoidable deposits.

[0003] Although visual inspection technology has been widely applied in this field, existing technologies still have significant limitations when dealing with the aforementioned impurities, primarily in accurately identifying the physical properties of shadow areas. Impurities adhering to the surface of a golf ball create specific shadow areas during image acquisition by visual inspection equipment. These shadow areas, formed by foreign impurities, are highly similar to real defects on the ball's surface (such as dents, scratches, or coating defects produced during manufacturing) in terms of image grayscale values, edge contours, and light reflection characteristics. For existing visual inspection algorithms, a "black spot" in a static image could be either a foreign impurity or a surface defect; this confusion of visual features directly affects the sorting accuracy of visual inspection equipment.

[0004] When a vision system detects a shadow area caused by foreign impurities, it often misjudges it as a product quality defect. This causes existing equipment to mistakenly reject a large number of high-quality golf balls that only have cleanable impurities on their surface and can be qualified after simple cleaning as defective products, resulting in production waste. Summary of the Invention

[0005] This invention provides an automatic golf ball sorting device, which uses a drive mechanism to agitate and purify golf balls with shadows on their surface using pulsed airflow, and uses a second vision inspection device to re-inspect whether the shadow area has shrunk in order to distinguish between removable impurities and permanent defects. This solves the problem in the prior art of wasting good products due to the difficulty in distinguishing between impurities attached to the surface of the ball and permanent defects.

[0006] To achieve the above objectives, the present invention provides an automatic golf ball sorting device comprising an industrial conveyor and two mounting brackets disposed on one side of the industrial conveyor, and further comprising a first reflector and a second reflector respectively disposed on the two mounting brackets, a first visual inspection device and a second visual inspection device respectively disposed on the top of the first reflector and the second reflector, a first good product conveying line disposed on one side of the first reflector, a defective product conveying line disposed on one side of the second reflector, and a driving mechanism disposed at the bottom of the first reflector, wherein both the first reflector and the second reflector are semi-elliptical and are used to reflect the image of the bottom of the ball.

[0007] In the above technical solution, when the first vision inspection device detects that the surface of the sphere is free of defects, the sphere is sent to the first good product conveyor line; when the first vision inspection device detects that the sphere has a shadow area, it is processed by the drive mechanism and sent to the second reflector for re-inspection by the second vision inspection device. If the shadow area is reduced, the sphere is sent to the first good product conveyor line; if it is not reduced, it is sent to the defective product conveyor line.

[0008] Based on the above, the surface treatment of the golf ball by the drive mechanism includes bouncing the golf ball and blowing the surface of the golf ball with pulsed airflow; a second good product conveyor line is provided on the other side of the second reflector and is connected to the first good product conveyor line.

[0009] The automatic golf ball sorting device also includes a first nozzle disposed on top of a first reflector and a second nozzle disposed on top of a second reflector.

[0010] The top of the mounting frame is rotatably equipped with a fixed frame, and a lifting block is slidably installed inside the fixed frame. The top of the lifting block is hinged with a movable rod. The top of the lifting block has a first notch, and the top of the fixed frame has a second notch. The number of fixed frames, lifting blocks and movable rods corresponds to the number of mounting frames. The tops of the two movable rods are respectively connected to the first reflector and the second reflector. A counterweight is fixedly connected to the outer wall of the first reflector and the second reflector near the second notch.

[0011] An L-shaped support plate is fixedly installed on the outer wall of the fixed frame, and a positioning cover is fixedly installed on the top surface of the mounting bracket. The inner wall of the positioning cover has an arc-shaped groove for limiting the rotation angle of the L-shaped support plate, and a plug rod inserted into the arc-shaped groove is fixedly connected to the outer wall of the L-shaped support plate.

[0012] The top surface of the mounting frame has a through slot, and the outer wall of the mounting frame is equipped with a first motor via a base. The base is mounted on the mounting frame in a height-adjustable manner. The output shaft of the first motor is connected to a drive disc for pushing the lifting block upward. The top outer wall of the movable rod is fixedly connected with an anti-detachment ring, and the outer wall of the drive disc is in contact with the bottom end of the lifting block.

[0013] A second motor is fixedly installed on the outer wall of the mounting bracket. The output shaft of the second motor is fixedly connected to a lever for pushing the L-shaped support plate to rotate, and the lever is V-shaped.

[0014] The drive disc includes a first protrusion, and the drive disc corresponding to the first reflector also includes a second protrusion.

[0015] The inner wall of the first reflector has a groove, and the inner wall of the first reflector also has a purge hole. The end of the purge hole is connected to a first air pump through a first air pipe.

[0016] A second air pipe connected to the groove is inserted into the top outer wall of the movable rod, and a second air pump is connected to the end of the second air pipe away from the movable rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This automatic golf ball sorting device utilizes a first and second visual inspection system, along with semi-elliptical first and second reflectors. Combined with a drive mechanism that agitates and purifies the balls with pulsed airflow, it achieves secondary inspection and classification of shadowed areas on the ball's surface. This effectively distinguishes between surface-adhered impurities and permanent production defects. Consequently, it solves the problem of incorrect rejection of good products due to the difficulty in identifying removable impurities, improving sorting accuracy and reducing production costs.

[0018] 2. In this automatic golf ball sorting device, the first and second protrusions on the drive disc, in conjunction with a lifting block, achieve the agitation and tumbling transfer of the balls. The adjustable base accommodates the agitation needs of golf balls with varying elasticity. Furthermore, the first and second nozzles automatically clean the inner wall of the reflector after the balls are separated, achieving smooth operation, adjustable cleaning intensity, and consistently clear detection visibility. This ensures the stability and reliability of the equipment's operation and prevents residual impurities from interfering with subsequent inspections. Attached Figure Description

[0021] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] Example 1, Reference Figure 1As shown, the present invention discloses an automatic golf ball sorting device, including an industrial conveyor 100 and two mounting brackets 101 disposed on one side of the industrial conveyor 100. It also includes a first reflector 102 and a second reflector 103 respectively disposed on the two mounting brackets 101, a first visual inspection device 107 and a second visual inspection device 108 respectively disposed on the top of the first reflector 102 and the second reflector 103, a first good product conveying line 104 disposed on one side of the first reflector 102, a defective product conveying line 106 disposed on one side of the second reflector 103, a second good product conveying line 105 disposed on the other side of the second reflector 103 and connected to the first good product conveying line 104, and a driving mechanism disposed at the bottom of the first reflector 102. The first reflector 102 and the second reflector 103 are both semi-elliptical in shape to reflect the image of the bottom of the golf ball.

[0023] It should be noted that both the first visual inspection device 107 and the second visual inspection device 108 consist of multiple ring-shaped inspection cameras. In this embodiment, the number of inspection cameras is preferably three, with one inspection camera in the center and the other two inspection cameras tilted and symmetrically arranged on either side of the central inspection camera. The multiple inspection cameras, combined with the semi-elliptical structure design of the first reflector 102 and the second reflector 103, can clearly reflect the image of the bottom and surrounding area of ​​the golf ball to the inspection camera at the top of the golf ball. This eliminates the blind spot at the bottom of the golf ball that is difficult to observe with traditional vertical shooting. Furthermore, this curved reflection design can also expand the field of view to a certain extent, allowing the first visual inspection device 107 and the second visual inspection device 108 to acquire more surface feature information at once, improving inspection efficiency.

[0024] Combination Figure 3 As shown, the surface of the golf ball is inspected by the first visual inspection device 107 via the first reflector 102. When it is determined that the surface of the golf ball is clean and free of defects, i.e. without shadow areas, it is transferred to the first good product conveyor line 104 through the L1 path.

[0025] Specifically, the system of this device adopts the existing machine vision-based automatic control system. When the golf ball is determined to be clean and flawless, the system will control the drive mechanism to directly pour the ball on the first reflector 102 into the first good product conveyor line 104. This path design is the most direct, effectively reducing the dwell time of qualified products in the device and improving the overall production cycle.

[0026] Combined Figure 3As shown, when the first vision inspection device 107 determines that there is a shadow area on the surface of the golf ball, it may be a permanent production defect. The system controls the drive mechanism to process the surface of the golf ball, and then transfers the golf ball to the second reflector 103. The second vision inspection device 108 inspects the processed surface of the golf ball through the second reflector 103. When it is determined that the shadow area has been reduced, it is transferred to the second good product conveyor line 105 through the L2 path and merged into the first good product conveyor line 104. When it is determined that the shadow area has not been reduced, it is transferred to the defective product conveyor line 106 through the C1 path.

[0027] The step of transferring the sphere to the second reflector 103 for re-inspection is based on the principle of distinguishing between removable impurities and permanent defects. If the shadow area shrinks, it indicates that the previous processing by the drive mechanism successfully removed the impurities attached to the sphere's surface, and the sphere is considered a good product. Therefore, it is collected through the second good product conveyor line 105 and eventually merged into the first good product conveyor line 104. If the shadow area does not shrink, it indicates that the shadow is a physical defect of the sphere itself, and the sphere is guided to the defective product conveyor line 106. Furthermore, the connection design between the second good product conveyor line 105 and the first good product conveyor line 104 cleverly realizes the automatic return of re-inspected qualified products without the need for additional collection equipment, simplifying the overall layout.

[0028] The drive mechanism's surface treatment of the golf ball includes bouncing the golf ball and swishing the surface of the golf ball with pulsed airflow.

[0029] It should be noted that the shaking motion utilizes the principle of physical vibration to break the adhesion between impurities and the surface of the sphere, especially effective against electrostatically adsorbed micro-dust, which can be loosened by shaking. The pulsed airflow purging, on the other hand, uses the impact force of a high-pressure airflow to blow the loosened impurities away from the sphere's surface. The combination of these two techniques significantly improves the cleaning effect on stubborn impurities, ensuring the accuracy of subsequent visual inspection.

[0030] refer to Figure 2 As shown, the automatic golf ball sorting device also includes a first nozzle 109 disposed on the top of the first reflector 102 and a second nozzle 110 disposed on the top of the second reflector 103.

[0031] Furthermore, after the sphere separates from the first reflector 102 and the second reflector 103, air is sprayed onto the inner wall of the first reflector 102 through the first nozzle 109. Combined with the curved surface of the first reflector 102, this effectively blows away impurities present on the first reflector 102. Similarly, the second nozzle 110 can blow away impurities present on the second reflector 103. Thus, by utilizing the curved surfaces of the first reflector 102 and the second reflector 103, along with the top first nozzle 109 and second nozzle 110, residual impurities on the inner walls can be automatically blown away after the sphere separates, effectively maintaining the cleanliness of the mirror surfaces to ensure the accuracy of subsequent visual inspection.

[0032] A fixed frame 200 is rotatably mounted on the top of the mounting bracket 101. A lifting block 203 is slidably mounted inside the fixed frame 200. A movable rod 204 is hinged to the top of the lifting block 203. A first notch 212 is opened at the top of the lifting block 203, and a second notch 213 is opened at the top of the fixed frame 200. The number of fixed frames 200, lifting blocks 203 and movable rods 204 corresponds to the number of mounting brackets 101. The tops of the two movable rods 204 are respectively connected to the first reflector 102 and the second reflector 103.

[0033] Specifically, since the hinge position between the lifting block 203 and the movable rod 204 is still inside the fixed frame 200 when the lifting block 203 has not risen to the preset height, this device can achieve the effect of shaking the sphere inside the first reflector 102 by controlling the lifting block 203 to rise and fall quickly.

[0034] pass Figure 9 As shown, because the hinge between the lifting block 203 and the movable rod 204 is disengaged from the interior of the fixed frame 200 when the lifting block 203 rises to its highest position, the movable rod 204 can tilt along the top of the lifting block 203. Combined with the first notch 212 and the second notch 213, the tilting angle of the movable rod 204 can be limited. Therefore, by controlling the rising height of the lifting block 203, two degrees of freedom of movement—bouncing the ball and tilting the transport ball—can be achieved, resulting in a compact structure and smooth operation.

[0035] An L-shaped support plate 201 is fixedly installed on the outer wall of the fixed frame 200, and a positioning cover 202 is fixedly installed on the top surface of the mounting bracket 101. An arc-shaped groove (not shown in the figure) is opened on the inner wall of the positioning cover 202 to limit the rotation angle of the L-shaped support plate 201. An insert rod (not shown in the figure) is fixedly connected to the outer wall of the L-shaped support plate 201 and inserted into the arc-shaped groove.

[0036] Specifically, the positioning cover 202 and its internal arc-shaped groove, along with the insertion rod, act as a mechanical limiter, ensuring that the L-shaped support plate 201 can only rotate horizontally and will not slide. When the fixed frame 200 rotates with the L-shaped support plate 201, the insertion rod slides within the arc-shaped groove. When it reaches the end of the arc-shaped groove, it is blocked, thereby precisely controlling the flip angle of the first reflector 102 and the second reflector 103, preventing excessive flipping that could cause the ball to fall in an inaccurate position or damage the equipment.

[0037] In addition, refer to Figure 9 As shown, counterweights 214 are fixedly connected to the outer walls of the first reflector 102 and the second reflector 103 in the direction near the second notch 213. When the lifting block 203 rises to the highest position, it causes the movable rod 204 to tilt.

[0038] Combination Figure 7 As shown, the top surface of the mounting bracket 101 has a through groove 207. The outer wall of the mounting bracket 101 is mounted with a first motor 205 via a base 300. The base 300 is movably mounted on the mounting bracket 101. The output shaft of the first motor 205 is connected to a drive disk 206 for pushing the lifting block 203 upward. The top outer wall of the movable rod 204 is fixedly connected with an anti-detachment ring 301, and the outer wall of the drive disk 206 contacts the bottom end of the lifting block 203. The drive disk 206 includes a first protrusion 210, and the drive disk 206 corresponding to the first reflector 102 also includes a second protrusion 211.

[0039] Specifically, the second protrusion 211 on the drive disk 206 is a key structure for realizing the tumbling motion of the first reflector 102, and the first protrusion 210 on the drive disk 206 is a key structure for realizing the tilting motion of the first reflector 102 and the second reflector 103. When the drive disk 206 rotates, the second protrusion 211 lifts the lifting block 203, and then the lifting block 203 falls, forming a tumbling motion. In addition, higher frequency vibrations can be generated by setting the number of second protrusions 211 or by adjusting the rotation angle and frequency of the output shaft of the first motor 205. The frequency setting can be changed according to actual usage requirements.

[0040] The through slot 207 provides the necessary space for the drive disk 206 to move. The first motor 205 can be a common servo motor in existing technology; its specific model can be determined according to actual usage requirements, and will not be elaborated here. Among these, combined with... Figure 4As shown, two sets of support plates are fixedly installed on the outer wall of the mounting bracket 101. A lead screw is rotatably mounted on the opposite surface of one set of support plates, and the top end of the lead screw passes through the top surface of the support plate and is fixedly connected to a knob. A guide rod is fixedly connected to the opposite surface of the other set of support plates. The outer wall of the base 300 is connected to the lead screw and slidably connected to the guide rod, so that the height of the base 300 can be adjusted by rotating the knob. Alternatively, a pin can be provided on the base 300, and multiple holes of different heights can be opened on the mounting bracket 101. The height of the base 300 can be changed by inserting the pin into the holes of different heights, or other adjustment methods can be used.

[0041] The height-adjustable design of the base 300 allows technicians to fine-tune the height of the first motor 205 and drive disc 206 according to the different elasticity (hardness) of the golf ball, so that the golf ball can generate a vibration effect when bounced without popping out the first reflector 102.

[0042] This embodiment illustrates two scenarios: In the first scenario, such as... Figure 6 As shown, the base 300 is in its highest position. Supported by the drive disc 206, the movable rod 204 and the anti-detachment ring 301 are in their highest positions, and the anti-detachment ring 301 is not in contact with the fixed frame 200. At this time, when the drive disc 206 rotates, the second protrusion 211 on its surface can push the lifting block 203 to bounce up and down significantly.

[0043] In the second scenario, the base 300 is in its lowest position, the anti-detachment ring 301 descends to contact the top of the fixed frame 200, and the drive disc 206 no longer contacts the bottom of the lifting block 203. When the drive disc 206 rotates, its second protrusion 211 can only push the lifting block 203 to bounce slightly up and down. This allows for flexible adjustment of the driving mechanism's vibration amplitude on the ball according to its different elasticity (hardness), ensuring that the golf ball vibrates during bouncing without popping out of the first reflector 102.

[0044] For example Figure 5 As shown, a second motor 208 is fixedly installed on the outer wall of the mounting bracket 101. The output shaft of the second motor 208 is fixedly connected to a lever 209 for pushing the L-shaped support plate 201 to rotate, and the lever 209 is V-shaped.

[0045] The second motor 208 can be a servo motor commonly used in the prior art. The V-shaped lever 209 is designed to better cooperate with the L-shaped support plate 201. When the output shaft of the second motor 208 rotates, the open end of the V-shape can push the side of the L-shaped support plate 201. As the rotation angle changes, a continuous pushing force is applied, thereby driving the fixed frame 200 to rotate smoothly, realizing the tilting action of the first reflector 102 and the second reflector 103. After tilting is completed, controlling the output shaft of the second motor 208 to reverse can push the L-shaped support plate 201 back to its initial position. It should be noted that it is only necessary to control the rotation of the output shaft of the second motor 208 when a defective ball appears; it is not necessary to control the rotation of the output shaft of the second motor 208 when only good balls pass through.

[0046] Combination Figure 4 and Figure 10 As shown, the inner wall of the first reflector 102 has a groove 400 and a purge hole 401. The end of the purge hole 401 is connected to a first air pump via a first air pipe 402. A second air pipe 403 communicating with the groove 400 is inserted into the top outer wall of the movable rod 204. The end of the second air pipe 403 away from the movable rod 204 is connected to a second air pump.

[0047] It should be noted that after the sphere is agitated by the drive mechanism, it rolls onto the groove 400 and is held in place by the negative pressure of the second air pipe 403. Subsequently, compressed air enters the first reflector 102 through the first air pipe 402 and is then evenly sprayed out through multiple blowholes 401 distributed on the inner wall of the first reflector 102. This bottom-up blowing method directly impacts the bottom of the sphere, effectively cleaning the dead corners and preventing impurities from accumulating on the reflector surface, thus maintaining a clean testing environment. Furthermore, while the multiple blowholes 401 evenly spray air, the first nozzle 109 also sprays air, impacting the top of the sphere and further enhancing the cleaning effect on the sphere's surface.

[0048] Working principle: First, the industrial conveyor 100 transports golf balls to the first reflector 102, where the first vision inspection device 107 inspects the surface of the ball via the first reflector 102. If the surface of the ball is determined to be free of defects, the system controls the drive mechanism to tilt the ball on the first reflector 102, allowing it to enter the first good product conveyor line 104 along path L1, thus completing rapid sorting.

[0049] If the first visual inspection device 107 determines that there is a shadow on the surface of the sphere, the drive mechanism starts to work. The first motor 205 drives the drive disk 206 to rotate. The second protrusion 211 pushes the lifting block 203, causing the first reflector 102 to bounce, which breaks the adhesion between the impurities and the sphere. After the bounce is completed, the negative pressure of the second air tube 403 adsorbs the sphere and fixes it. Then, the pulse airflow ejected from the blow hole 401 cleans the surface of the sphere. It should be noted that since the negative pressure of the second air tube 403 firmly adsorbs the sphere, the intensity of the pulse airflow ejected from the blow hole 401 will not cause the sphere to shake.

[0050] After cleaning, the drive disk 206 continues to rotate, further lifting the lifting block 203 through the first protrusion 210, freeing it from the constraint of the fixed frame 200, thereby causing the first reflector 102 to flip and transfer the sphere to the second reflector 103 for re-inspection. Based on the detection results of the first visual inspection device 107, the second visual inspection device 108 finds that the area of ​​the shadow region has shrunk after re-inspection. If the area is found to be an impurity, the sphere enters the second good product conveyor line 105 via path L2 and merges into the first good product conveyor line 104. If the area of ​​the shadow region has not shrunk, the area is determined to be a permanent production defect, and the sphere enters the defective product conveyor line 106 via path C1.

[0051] Furthermore, after the ball separates, the first nozzle 109 and the second nozzle 110 respectively spray air to clean the inner walls of the first reflector 102 and the second reflector 103, using the arc-shaped structure to blow away residual impurities. Simultaneously, by adjusting the height of the base 300, the engagement relationship between the drive disc 206 and the lifting block 203 can be finely adjusted, thereby adjusting the amplitude of the bounce according to the different elasticity levels of the golf ball to prevent it from popping out.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
