Automatic bead loading device

Abstract

This invention proposes an automatic ball loading device, including a ball feeding mechanism, an assembly mechanism, and a conveying mechanism. The ball feeding mechanism includes a large ball unloading component and a small ball unloading component. The assembly mechanism includes a pushing component and a limiting component. The limiting component includes a large ball placement component, a small ball placement component, and a rail placement component. The large ball unloading component is connected to the large ball placement component via a large ball conveying pipe, and the small ball unloading component is connected to the small ball placement component via a small ball conveying pipe.

Simultaneously, after the conveying mechanism conveys the rail to the rail placement component, the pushing component pushes the large and small balls to the large and small ball assembly slots on the rail for assembly. This allows for the simultaneous assembly of multiple different balls at a time, without affecting assembly efficiency due to excessively large spacing between two balls on the same side.

Description

Technical Field

[0001] This invention relates to the field of bead-filling equipment technology, and more specifically to an automatic bead-filling device. Background Technology

[0002] A slide rail is a track on which moving parts slide. It is generally groove-shaped, with ball bearings fixed to the end of the moving part. By engaging the ball bearings in the grooves of the slide rail, the moving part can slide within the grooves, thus allowing the moving part to move on the slide rail. For example... Figure 4 The rail shown has small ball bearing assembly slots and large ball bearing assembly slots at both ends, located on both sides of the rail, providing at least four ball bearing positions. At least four balls need to be installed during assembly. If both small and large balls are assembled manually, the assembly efficiency is low. Existing ball bearing installation devices can only install one type of ball bearing at a time, and if the distance between two balls on the same side is too large, only one ball bearing can be installed at a time, resulting in low assembly efficiency.

Detailed Implementation

[0022] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] Example: Please refer to Figure 1-4 An automatic ball loading device includes a frame 5, a ball feeding mechanism 1, an assembly mechanism 2, and a conveying mechanism 3. The ball feeding mechanism 1, the conveying mechanism 3, and the assembly mechanism 2 are all mounted on the frame 5. Large and small balls in the ball 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 ball feeding mechanism 1 includes a large ball feeding assembly 11 and a small ball feeding assembly 12. The large ball feeding assembly 11 includes a large ball flexible vibrating plate, and a large ball tube connector is connected to one side of the bottom of the large ball flexible vibrating plate. The large ball tube connector is connected to the large ball conveying pipe. The small ball feeding assembly 12 includes a small ball flexible vibrating plate, and a small ball tube connector is connected to one side of the bottom of the flexible vibrating plate. The small ball tube connector is connected to the small ball conveying pipe. Through vibration, the large balls in the large ball flexible vibrating plate are conveyed to the next process through the large ball conveying pipe, and the small balls in the small ball flexible vibrating plate are conveyed to the next process through the small ball conveying pipe.

[0025] It also includes a bead detection mechanism 4, which is mounted on the frame 5. The bead detection mechanism 4 includes a large bead detection component 41 and a small bead detection component 42. The input end of the large bead detection 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 detection component 41 is connected to the large bead placement component through the large bead conveying pipe. The input end of the small bead detection 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 detection component 42 is connected to the small bead placement component through the small bead conveying pipe.

[0026] The large ball detection assembly 41 includes a fixed block 411 and a movable block 412. The movable block 412 is mounted on the fixed block 411, and a drive structure 413, which is a ball-separating cylinder, is connected to one side of the movable block 412. A large ball detection channel 414 is provided on the movable block 412, and a detection groove 415 communicating with the large ball detection channel 414 is provided on the movable block 412. The length and width of the detection groove 415 are smaller than the diameter of the large ball to prevent the large ball from falling out of the detection groove 415.

[0027] A ball detection structure 417 is installed on the ball detection groove 415. The ball detection structure 417 includes a ball detection cylinder 4171, a ball detection block 4172, a displacement sensor 4173, and a detection plate 4174. The output end of the ball detection cylinder 4171 is connected to a fixing rod 4175, which is connected to the ball detection block 4172. The ball detection block 4172 can pass through the ball detection groove 415 and reach the large ball detection channel 414. The height of the ball detection block 4172 is lower than the diameter of the large ball but higher than the radius of the large ball, so that the ball detection block 4172 can better press the large ball. The displacement sensor 4173 is installed on the ball detection cylinder 4171, and the detection plate 4174 is installed on the fixing rod 4175. The displacement sensor 4173 and the detection plate 4174 cooperate, and the displacement sensor 4173 detects the size of the large ball by moving the detection plate 4174. A fixing plate is installed on the fixing rod 4175 between the detection plate 4174 and the ball detection groove 415. A first limiting groove is formed on the moving block 412 directly above the ball detection groove 415. A first limiting plate 4176 is installed in the first limiting groove and is connected to the fixing plate. A through hole 4177 is formed on the first limiting plate 4176, and the diameter of the through hole 4177 is larger than the diameter of the large ball. A second limiting groove is formed on the moving block 412 at the bottom of the ball detection groove 415. A second limiting plate 4178 is installed in the second limiting groove and 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 a large ball enters the large ball detection channel 414, the detection cylinder 4171 extends, driving the fixed rod 4175 to move. The movement of the fixed rod 4175 causes the detection plate 4174, the detection block 4172, the fixed plate, the first limit plate 4176, and the second limit plate 4178 to move. During the movement of the first limit plate 4176, the large ball on the first limit plate 4176 falls from the through hole 4177 onto the detection block 4172. At the same time, the second limit plate 4178 receives the large ball. Because the first limit plate 4176 is moving, when a large ball falls from the through hole 4177, the through hole 4177 is blocked, preventing another adjacent large ball from falling from the through hole 4177. Then, the detection block 4172 is driven to press the large ball. By calculating the extension distance of the detection cylinder 4171, it can be determined whether the specifications of the large ball meet the requirements. After the detection is completed, the detection cylinder 4171 retracts, driving... The fixed rod 4175 moves, which 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 back. At the same time, due to the first limiting plate 4176 and the second limiting plate 4178, when the through hole 4177 on the first limiting plate 4176 is located in the middle of the large bead detection channel 414, the large ball on the first limiting plate 4176 abuts against the large ball on the second limiting plate 4178 that has been detected, and cannot fall from the through hole 4177 onto the second limiting plate 4178. Then the first limiting plate 4176 and the second limiting plate 4178 continue to move until the through hole 4177 on the first limiting plate 4176 is blocked. At this time, the large ball on the first limiting plate 4176 will not fall. After the end of the second limiting plate 4178 reaches the position of the bead detection groove 415, the large ball that has been detected falls downward. Thus, we begin the test of the next large ball bearing.

[0029] The fixed block 411 has a qualified channel 416, and the large ball inspection channel 414 is connected to the qualified channel 416. The large ball conveying pipe is connected to the large ball inspection channel 414 and the qualified channel 416. The large ball inspection assembly 41 also includes an NG fixing groove 418, which is installed on one side of the fixed block 411 and is connected to the large ball inspection channel 414. The fixed block 411 is inclined towards the end of the NG fixing groove 418. When a large ball enters the large ball inspection channel 414 and is in the inspection state, if the specifications of the large ball meet the requirements, the inspection cylinder 4171 retracts, driving the inspection block 4172 to retract. The large ball flows from the large ball inspection channel 414 into the qualified channel 416, and then from the qualified channel 416 through the large ball conveying pipe to the next process. If the specifications of the large ball bearings do not meet the requirements, the ball-separating cylinder extends, pushing the moving block 412 to misalign the large ball inspection channel 414 with the qualified channel 416, making them disconnected. The large ball inspection channel 414 then connects with the NG fixing groove 418. Next, the inspection cylinder 4171 retracts, causing the inspection block 4172 to retract. The large ball bearings flow from the large ball inspection channel 414 into the NG fixing groove 418, and then from the NG fixing groove 418 into the NG ball collection box. The structure and connection method of the small ball inspection assembly 42 are the same as those of the large ball inspection assembly 41, and the detection method for the small ball bearing specifications is the same as that for the large ball bearing specifications.

[0030] The conveying mechanism 3 is located directly above the assembly mechanism 2. The conveying mechanism 3 includes a Y-axis moving component 31, a Z-axis moving component 32, and a clamping component 33. The Y-axis moving component 31 is mounted on the frame 5, the Z-axis moving component 32 is mounted on the Y-axis moving component 31, and the clamping component 33 is mounted on the Z-axis moving component 32. The Y-axis moving component 31 can be a guide rail system, a screw system, or a Y-axis cylinder system, all of which are existing technologies and will not be described in detail. The Z-axis moving component 32 includes a Z-axis cylinder, the output end of which is connected to the clamping component 33. The clamping component 33 includes a finger cylinder for clamping the rail 6. The conveying mechanism 3 achieves the clamping of the rail 6 and its movement in the Y and Z axes.

[0031] 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, with the output end of the pushing cylinder 211 connected to the pushing rod 212. The limiting component 22 includes a large ball placement component, a small ball placement component, and a rail placement component. The large ball placement component and the small ball placement component are respectively installed on both sides of the rail placement component. The pushing component 21 is respectively installed on the side of the large ball placement component and the small ball placement component away from the rail placement component. The large ball feeding component 11 is connected to the large ball placement component through a large ball conveying pipe, and the small ball feeding component 12 is connected to the small ball placement component through a small ball conveying pipe. This allows for the simultaneous assembly of large and small balls on both sides of the rail 6.

[0032] The rail placement component includes a concave placement block 221. Both ends of the concave placement block 221 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 end of the rail 6. The concave position in the middle of the concave placement block 221 can facilitate the clamping of the rail 6 by the finger cylinder of the clamping component 33.

[0033] The ball bearing placement component includes two ball bearing limiting blocks 223, which are respectively installed at both ends of the concave placement block 221, enabling ball bearing assembly in the ball bearing assembly slots 62 at both ends of the rail 6. The ball bearing limiting blocks 223 have inverted T-shaped through holes 224 for the ball bearings. One side of each end of the concave placement block 221 has a ball bearing channel. Both the ball bearing channel and the ball bearing conveying pipe are connected to the inverted T-shaped through holes 224, allowing the output end of the pushing component 21 to penetrate into the inverted T-shaped through holes 224. After the ball bearings are tested, they are conveyed to the inverted T-shaped through holes 224 through the ball bearing conveying pipe. Then, the cylinder 211 extends, driving the pushing rod 212 to penetrate into the inverted T-shaped through holes 224, pushing the ball bearings into the ball bearing channel and pressing them into the ball bearing assembly slots 62 of the rail 6, completing the ball bearing assembly.

[0034] The ball bearing placement component includes two ball bearing limiting blocks 225, which are respectively installed at both ends of the concave placement block 221, allowing for ball bearing assembly in the ball bearing assembly slots 61 at both ends of the rail 6. Each ball bearing limiting block 225 has an inverted T-shaped through hole 226 for the ball bearings. A ball bearing channel is formed on one side of each end of the concave placement block 221. Both the ball bearing channel and the ball bearing conveying pipe are connected to the inverted T-shaped through hole 226, allowing the output end of the pushing component 21 to penetrate into the inverted T-shaped through hole 226. After ball bearing detection, the ball bearings are conveyed to the inverted T-shaped through hole 226 via the ball bearing conveying pipe. Then, the cylinder 211 extends, driving the pushing rod 212 to penetrate into the inverted T-shaped through hole 226, pushing the ball bearings into the ball bearing channel and pressing them into the ball bearing assembly slots 61 of the rail 6, completing the ball bearing assembly. After assembly, the ball bearings are then conveyed out via the conveying mechanism 3. This allows for the simultaneous assembly of multiple different balls, without affecting assembly efficiency due to excessive spacing between two balls on the same side.

[0035] Working principle

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

[0037] Simultaneously, through vibration, the large balls in the large ball flexible vibrating plate are transported to the large ball detection component 41 via the large ball conveying pipe, and the small balls in the small ball flexible vibrating plate are transported to the small ball detection component 42 via the small ball conveying pipe. When the large ball enters the large ball detection channel 414 and is in the detection state, the large ball detection channel 414 is connected to the qualified channel 416, the detection cylinder 4171 extends, and drives the detection block 4172 to press the large ball. By calculating the extension distance of the detection cylinder 4171, it can be determined whether the specifications of the large ball meet the requirements. If the large ball bearing meets the specifications, the ball bearing inspection cylinder 4171 retracts, causing the ball bearing inspection block 4172 to retract as well. The large ball bearing flows from the large ball bearing inspection channel 414 into the qualified channel 416, and then from the qualified channel 416 through the large ball bearing conveying pipe to the next process. If the large ball bearing does not meet the specifications, the ball bearing separation cylinder extends, pushing the moving block 412 to misalign the large ball bearing inspection channel 414 with the qualified channel 416, connecting the large ball bearing inspection channel 414 with the NG fixing groove 418. Then, the ball bearing inspection cylinder 4171 retracts, causing the ball bearing inspection block 4172 to retract as well. The large ball bearing flows from the large ball bearing inspection channel 414 into the NG fixing groove. The detection steps for small balls are the same as those for large balls.

[0038] The qualified large ball bearings are conveyed through the large ball bearing conveying pipe to the large ball bearing inverted T-shaped through hole 224. Then, the cylinder 211 is pushed out, driving the push rod 212 to penetrate into the large ball bearing inverted T-shaped through hole 224, pushing the large ball bearing into the large ball bearing channel, and pressing it into the large ball bearing assembly groove 62 of the rail 6, completing the large ball bearing assembly. The qualified small ball bearings are conveyed through the small ball bearing conveying pipe to the small ball bearing inverted T-shaped through hole 226. Then, the cylinder 211 is pushed out, driving the push rod 212 to penetrate into the small ball bearing inverted T-shaped through hole 226, pushing the small ball bearing into the small ball bearing channel, and pressing it into the small ball bearing assembly groove 61 of the rail 6, completing the small ball bearing assembly.

[0039] After assembly, it is transported out via conveyor mechanism 3.
