DETAILED DESCRIPTION

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] Example: Please refer to Figure 1-4 An automatic bead loading device includes a frame 5, a bead feeding mechanism 1, an assembly mechanism 2 and a conveying mechanism 3, wherein the bead feeding mechanism 1, the conveying mechanism 3 and the assembly mechanism 2 are all mounted on the frame 5. The large balls and small balls in the bead feeding mechanism 1 are conveyed to the assembly mechanism 2; at the same time, the conveying mechanism 3 conveys the rail 6 to the assembly mechanism 2 for assembly.

[0024] The bead feeding mechanism 1 includes a large bead feeding component 11 and a small bead feeding component 12. The large bead feeding component 11 includes a large bead flexible vibration disk, one side of the bottom of the large bead flexible vibration disk is connected with a large bead pipe joint, and the large bead pipe joint is connected with the large bead conveying pipe; the small bead feeding component 12 includes a small bead flexible vibration disk, one side of the bottom of the flexible vibration disk is connected with a small bead pipe joint, and the small bead pipe joint is connected with the small bead conveying pipe. Through the vibration relationship, the large balls in the large bead flexible vibration disk are transported to the next process through the large bead conveying pipe, and the small balls in the small bead flexible vibration disk are transported to the next process through the small bead conveying pipe.

[0025] It also includes a bead inspection mechanism 4, which is installed on the frame 5. The bead inspection mechanism 4 includes a large bead inspection component 41 and a small bead inspection component 42. The input end of the large bead inspection component 41 is connected to the large bead feeding component 11 through the large bead conveying pipe, and the output end of the large bead inspection component 41 is connected to the large bead placement component through the large bead conveying pipe; the input end of the small bead inspection component 42 is connected to the small bead feeding component 12 through the small bead conveying pipe, and the output end of the small bead inspection component 42 is connected to the small bead placement component through the small bead conveying pipe.

[0026] The large bead inspection assembly 41 includes a fixed block 411 and a moving block 412. The moving block 412 is mounted on the fixed block 411. A driving structure 413 is connected to one side of the moving block 412. The driving structure 413 is a bead separation cylinder. A large bead inspection channel 414 is provided on the moving block 412. A bead inspection groove 415 connected to the large bead inspection channel 414 is provided on the moving block 412. The length and width of the bead inspection groove 415 are smaller than the diameter of the large ball to prevent the large ball from falling out of the bead inspection groove 415.

[0027] A bead detecting structure 417 is installed on the bead detecting groove 415. The bead detecting structure 417 includes a bead detecting cylinder 4171, a bead detecting block 4172, a displacement sensor 4173 and a detection plate 4174. The output end of the bead detecting cylinder 4171 is connected to a fixed rod 4175, and the fixed rod 4175 is connected to the bead detecting block 4172. The bead detecting block 4172 can pass through the bead detecting groove 415 and directly reach the large bead detecting channel 414. The height of the bead detecting block 4172 is lower than the diameter of the large ball and higher than the radius of the large ball, so that the bead detecting block 4172 can better suppress the large ball; the displacement sensor 4173 is installed on the bead detecting cylinder 4171, and the detection plate 4174 is installed on the fixed rod 4175. The displacement sensor 4173 and the detection plate 4174 cooperate, and the displacement sensor 4173 detects the specifications of the large ball through the movement of the detection plate 4174. A fixing plate is installed on the fixing rod 4175 between the detection plate 4174 and the bead detection groove 415. A first limiting groove is provided on the moving block 412 just above the bead detection groove 415. A first limiting plate 4176 is installed in the first limiting groove. The first limiting plate 4176 is connected to the fixing plate. A through hole 4177 is provided on the first limiting plate 4176. The diameter of the through hole 4177 is larger than the diameter of the large ball. A second limiting groove is provided on the moving block 412 at the bottom end of the bead detection groove 415. A second limiting plate 4178 is installed in the second limiting groove. The second limiting plate 4178 is connected to the fixing rod 4175. The first limiting plate 4176 and the second limiting plate 4178 are slightly larger than the diameter of the large ball.

[0028] When the large ball enters the large ball detection channel 414, the bead detection cylinder 4171 extends out, driving the fixed rod 4175 to move. The movement of the fixed rod 4175 drives the detection plate 4174, the bead detection block 4172, the fixed plate, the first limiting plate 4176 and the second limiting plate 4178 to move. During the movement of the first limiting plate 4176, the large ball on the first limiting plate 4176 falls from the through hole 4177 to the bead detection block 4172; at the same time, the second limiting plate 4178 receives the large ball, because during the movement of the first limiting plate 4176, when a large ball falls from the through hole 4177, the through hole 4177 is blocked, and the other adjacent large ball cannot fall from the through hole 4177, and then drives the bead detection block 4172 to suppress the large ball. By calculating the extended distance of the bead detection cylinder 4171, it can be known whether the specifications of the large ball meet the requirements; after the detection is completed, the bead detection cylinder 4171 retracts and drives The fixed rod 4175 moves, and the movement of the fixed rod 4175 drives the detection plate 4174, the bead detection block 4172, the fixed plate, the first limit plate 4176 and the second limit plate 4178 to move back. At the same time, because of the first limit plate 4176 and the second limit plate 4178, when the through hole 4177 on the first limit plate 4176 is located in the middle of entering the large bead detection channel 414, the large ball on the first limit plate 4176 is against the large ball that has been detected on the second limit plate 4178, and cannot fall from the through hole 4177 to the second limit plate 4178; then the first limit plate 4176 and the second limit plate 4178 continue to move until the through hole 4177 on the first limit plate 4176 is blocked. At this time, the large ball on the first limit plate 4176 will not fall. After the end of the second limit plate 4178 reaches the position of the bead detection groove 415, the large ball that has been detected falls downward. Thus, the detection of the next large ball begins.

[0029] The fixed block 411 is provided with a qualified channel 416, and the large bead inspection channel 414 is connected to the qualified channel 416; the large bead conveying tube is connected to the large bead inspection channel 414, and the large bead conveying tube is connected to the qualified channel 416; the large bead inspection assembly 41 also includes an NG fixed groove 418, which is installed on one side of the fixed block 411, and the NG fixed groove 418 is connected to the large bead inspection channel 414, and the fixed block 411 is inclined toward the NG fixed groove 418. When the large ball enters the large bead inspection channel 414 and is in the bead inspection state. If the specifications of the large ball meet the requirements, the bead inspection cylinder 4171 retracts, driving the bead inspection block 4172 to retract, and the large ball flows from the large bead inspection channel 414 into the qualified channel 416, and then is transported from the qualified channel 416 to the next process through the large bead conveying tube. If the specification of the large ball does not meet the requirements, the ball separation cylinder extends and pushes the moving block 412, so that the large ball detection channel 414 is misaligned with the qualified channel 416, becoming a non-connected state, and the large ball detection channel 414 is connected with the NG fixed groove 418; then the bead detection cylinder 4171 retracts, driving the bead detection block 4172 to retract, and the large ball flows from the large bead detection channel 414 into the NG fixed groove 418, and then flows into the NG ball collection box from the NG fixed groove 418. The structure and connection method of the small bead detection assembly 42 are the same as those of the large bead detection assembly 41, and the detection method of the small ball specification is the same as that of the large ball specification.

[0030] The conveying mechanism 3 is located just above the assembly mechanism 2. The conveying mechanism 3 includes a Y-axis moving member 31, a Z-axis moving member 32 and a clamping member 33. The Y-axis moving member 31 is installed on the frame 5, the Z-axis moving member 32 is installed on the Y-axis moving member 31, and the clamping member 33 is installed on the Z-axis moving member 32. The Y-axis moving member 31 is a guide rail system or a screw system or a Y-axis cylinder system, which are all prior arts, so they are not repeated here. The Z-axis moving member 32 includes a Z-axis cylinder, and the output end of the Z-axis cylinder is connected to the clamping member 33. The clamping member 33 includes a finger cylinder for clamping the rail 6. The conveying mechanism 3 realizes the clamping of the rail 6 and the movement in the Y-axis direction and the Z-axis direction.

[0031] The assembly mechanism 2 includes a pushing component 21 and a limiting component 22. The pushing component 21 includes a pushing cylinder 211 and a pushing rod 212. The output end of the pushing cylinder 211 is connected to the pushing rod 212. The limiting component 22 includes a large bead placement part, a small bead placement part and a rail placement part. The large bead placement part and the small bead placement part are respectively installed on both sides of the rail placement part. The pushing component 21 is respectively installed on the side of the large bead placement part and the small bead placement part away from the rail placement part. The large bead feeding component 11 is connected to the large bead placement part through the large bead conveying pipe, and the small bead feeding component 12 is connected to the small bead placement part through the small bead conveying pipe. In this way, the large balls and small balls on both sides of the rail 6 can be assembled at the same time.

[0032] The rail placement piece includes a concave placement block 221, both ends of which are provided with placement grooves 222. The cross-sectional shape of the placement grooves 222 is adapted to the rail 6. The placement grooves 222 can be used to place the ends of the rail 6. The concave position in the middle of the concave placement block 221 can facilitate the finger cylinder of the clamping piece 33 to clamp the rail 6.

[0033] The large ball placement part includes two large ball limit blocks 223, which are respectively installed at the two ends of the concave placement block 221, and can assemble large balls in the large ball assembly grooves 62 at the two ends of the rail 6. The large ball limit blocks 223 are provided with large ball inverted T-shaped through holes 224, and one side of the two ends of the concave placement block 221 is provided with large ball channels. The large ball channels and the large ball conveying pipes are both connected to the large ball inverted T-shaped through holes 224, and the output end of the pushing component 21 can penetrate into the large ball inverted T-shaped through holes 224. After the large ball detection is completed, it is transported to the large ball inverted T-shaped through holes 224 through the large ball conveying pipe, and then the cylinder 211 is pushed out to drive the push rod 212 to penetrate into the large ball inverted T-shaped through holes 224, and the large ball is pushed to the large ball channel, and then pressed into the large ball assembly groove 62 of the rail 6 through the large ball channel to complete the large ball assembly.

[0034] The small ball placement part includes two small ball limit blocks 225, which are respectively installed at the two ends of the concave placement block 221, and can assemble small balls in the small ball assembly grooves 61 at the two ends of the rail 6. The small ball limit block 225 is provided with a small ball inverted T-shaped through hole 226, and one side of the two ends of the concave placement block 221 is provided with a small ball channel. The small ball channel and the small ball delivery tube are both connected to the small ball inverted T-shaped through hole 226, and the output end of the push component 21 can penetrate into the small ball inverted T-shaped through hole 226. After the small ball is detected, it is transported to the small ball inverted T-shaped through hole 226 through the small ball delivery tube, and then the cylinder 211 is pushed out, driving the push rod 212 to penetrate into the small ball inverted T-shaped through hole 226, pushing the small ball to the small ball channel, and passing through the small ball channel to press into the small ball assembly groove 61 of the rail 6 to complete the small ball assembly. After the assembly is completed, it is then transported out through the conveying mechanism 3. In this way, multiple balls and different balls can be assembled at the same time, and the assembly efficiency will not be affected by the large distance between two balls on the same side.

[0035] How it works

[0036] When the rail 6 needs to be assembled, the clamping member 33 clamps the rail 6, and then the rail 6 is placed on the concave placement block 221 under the movement of the Y-axis moving member 31 and the Z-axis moving member 32.

[0037] At the same time, through the vibration relationship, the large balls in the large ball flexible vibration disk are transported to the large ball detection assembly 41 through the large ball delivery tube, and the small balls in the small ball flexible vibration disk are transported to the small ball detection assembly 42 through the small ball delivery tube; when the large balls enter the large ball detection channel 414 and are in the bead detection state, the large bead detection channel 414 is connected with the qualified channel 416, and the bead detection cylinder 4171 extends, driving the bead detection block 4172 to press the large balls. The distance that the bead detection cylinder 4171 extends is calculated, so as to know whether the specifications of the large balls meet the requirements. If the specifications of the large balls meet the requirements, the bead detecting cylinder 4171 retracts, driving the bead detecting block 4172 to retract, and the large balls flow from the large bead detecting channel 414 into the qualified channel 416, and then are transported from the qualified channel 416 to the next process through the large bead conveying pipe; if the specifications of the large balls do not meet the requirements, the bead separating cylinder extends to push the moving block 412, so that the large bead detecting channel 414 and the qualified channel 416 are misaligned, and the large bead detecting channel 414 is connected to the NG fixing groove 418; then the bead detecting cylinder 4171 retracts, driving the bead detecting block 4172 to retract, and the large balls flow from the large bead detecting channel 414 into the NG fixing; the detection steps of the small balls are the same as the detection of the large balls mentioned above.

[0038] The qualified large ball is transported to the large ball inverted T-shaped through hole 224 through the large ball transport tube, and then the cylinder 211 is pushed out, driving the push rod 212 to go deep into the large ball inverted T-shaped through hole 224, pushing the large ball to the large ball channel, and passing through the large ball channel to press into the large ball assembly groove 62 of the track bar 6, completing the large ball assembly. The qualified small ball is transported to the small ball inverted T-shaped through hole 226 through the small ball transport tube, and then the cylinder 211 is pushed out, driving the push rod 212 to go deep into the small ball inverted T-shaped through hole 226, pushing the small ball to the small ball channel, and passing through the small ball channel to press into the small ball assembly groove 61 of the track bar 6, completing the small ball assembly.

[0039] After the assembly is completed, it is transported out through the transport mechanism 3.
