Description

A screw automatic sorting machine flipping mechanism Technical Field

[0001] This invention relates to the field of screw sorting equipment, specifically to a screw automatic sorting machine flipping mechanism. Background Technology

[0002] In the post-processing of standard parts such as screws and bolts during production or assembly, it is often necessary to arrange, feed, or package them in a uniform manner. Common sorting methods include vibratory feeders and vision-guided robotic arms. When sorting screws by a vibratory feeder, the screws are in a state with the head facing up and the thread facing down. To change them to a state with the head facing down and the thread facing up, the sorted screws need to be flipped. At this time, an automatic screw sorting machine flipping mechanism is needed to automatically flip the screws.

[0003] In actual use, the existing automatic screw sorting machine flipping mechanism generally involves a robotic arm to clamp the screws first and then flip them. This process involves many steps, has a relatively complex structure, and generally lacks continuity, which can affect work efficiency and make it inconvenient to use. Therefore, there is an urgent need to improve the technology of the automatic screw sorting machine flipping mechanism to perfect this equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a flipping mechanism for an automatic screw sorting machine. By setting up a flipping mechanism and a magnetic attraction mechanism, the flipping mechanism automatically flips the flipping seat, while the magnetic attraction mechanism stably attracts and releases the screws in the magnetic groove. This realizes the automatic flipping and posture adjustment of the screws during the conveying process. The structure is compact and the operation is smooth. No additional clamping or robotic arm operation is required, which effectively simplifies the process and improves sorting efficiency, thereby solving the problems mentioned in the background art in the current market.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a screw automatic sorting machine flipping mechanism, comprising a base, an L-shaped mounting seat fixedly connected to the top of the base, a connecting shaft fixedly connected to the middle of the top of the base, a fixed sleeve fixedly connected to the top of the connecting shaft, a rotating sleeve fitted outside the fixed sleeve, a transmission shaft fixedly connected to the middle of the top of the rotating sleeve, a drive motor fixedly connected to the top of the transmission shaft, and the drive motor embedded in the L-shaped mounting seat; six flipping seats are provided outside the fixed sleeve, each of the six flipping seats has multiple magnetic grooves on its side, a flipping mechanism is provided inside the fixed sleeve to flip the flipping seats, a magnetic attraction mechanism is provided at the magnetic grooves to attract screws, a screw unloading rack is provided on one side of the rotating sleeve, a support frame is provided at the front of the base, and a conveyor belt is provided inside the support frame.

[0006] Preferably, both the fixed sleeve and the rotating sleeve are open at the bottom, and the external dimensions of the fixed sleeve are smaller than the internal dimensions of the rotating sleeve.

[0007] Preferably, the cross-sections of the fixed sleeve and the rotating sleeve are circular, and the centers of the cross-sections of the fixed sleeve and the rotating sleeve coincide.

[0008] Preferably, the outer end of the rotating sleeve has six through holes, which correspond to the positions of six flip seats. A coil roller is rotatably connected inside each through hole. One end of the coil roller is connected to its corresponding flip seat, and the other end of the coil roller is fixedly connected to an arc-shaped plate. The arc-shaped plate is located between the fixed sleeve and the rotating sleeve. Two symmetrically arranged sliding rods are fixedly connected to the end of the arc-shaped plate near the fixed sleeve. Two L-shaped connecting rods are fixedly connected to the inner top wall of the fixed sleeve. The other end of the L-shaped connecting rods is connected to the inner side wall of the fixed sleeve. The front and rear ends of the fixed sleeve are provided with a first opening groove, a connecting groove, and a second opening groove.

[0009] Preferably, there are six sets of through holes and coil rollers, and the central axes of the through holes and coil rollers coincide.

[0010] Preferably, the sliding rod is provided with a polished layer at the contact points with the fixing sleeve, the first opening groove, the connecting groove, and the second opening groove.

[0011] Preferably, the first opening groove, the connecting groove, and the second opening groove are connected, and the cross-sections of the first opening groove, the connecting groove, and the second opening groove are inverted Y-shaped.

[0012] Preferably, a pressure rod is fixedly connected to the outer end of the coil roller. The pressure rod is located outside the rotating sleeve. Six power switches are embedded in the outer end of the rotating sleeve. The six power switches correspond to the positions of the six coil rollers. The cross-section of the power switches is arc-shaped, and a notch is opened at the bottom of the power switches.

[0013] Preferably, the arc-shaped energizer is arranged around the outer periphery of the coil roller, and the edge of the energizer is a rounded transition.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a flipping mechanism and a magnetic attraction mechanism, the present invention enables the flipping mechanism to rotate 180° when one of the flipping seats rotates to the first opening slot, the connecting slot and the second opening slot after adsorbing some screws during the continuous rotation of the rotating sleeve driven by the drive motor. The flipping mechanism automatically flips the flipping seat, and at the same time, the magnetic attraction mechanism stably adsorbs and releases the screws in the magnetic slot. This realizes the automatic flipping and posture adjustment of the screws during the conveying process. The structure is compact and the action is smooth. No additional clamping or robotic arm operation is required, which effectively simplifies the process and improves sorting efficiency.

[0015] This invention features a first opening slot, a connecting slot, and a second opening slot. A controller operates a drive motor, which rotates a rotating sleeve counter-clockwise. The rotating sleeve, in turn, rotates the flipping seat and the coil roller together. The coil roller causes a sliding rod at one end of the arc-shaped plate to slide along the bottom edge of the fixed sleeve. When the sliding rod reaches the first opening slot, it flips and slides out through the second opening slot, completing one flipping operation. The pressure rod rotates to the notch, causing the screws in the magnetic trough to fall onto the conveyor belt due to power failure. The first opening slot has two locations. When the sliding rod in one first opening slot flips, the sliding rod in the other first opening slot also flips simultaneously, causing the pressure rod to press the power switch again, regenerating magnetism in the magnetic trough to attract the subsequently sorted screws, making it convenient to use.

[0016] This invention features an energized switch. When the rotating sleeve rotates, the pressure rod rotates with the coil roller. Upon contact with the energized switch, the coil roller is energized, generating a magnetic force to attract the screw. When the pressure rod rotates to the notch position, the circuit is disconnected, demagnetizing the coil roller and releasing the screw. This achieves automatic control of magnetic attraction and release without the need for additional sensors or control systems. Furthermore, the edge of the energized switch is rounded, allowing the pressure rod to smoothly contact and leave the energized switch as it rotates with the coil roller, avoiding jamming or impact caused by sharp edges and ensuring the continuity and stability of the magnetic attraction mechanism.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Embodiments

[0020] Please refer to Figures 1 to 6. The present invention provides a technical solution: a screw automatic sorting machine flipping mechanism, including a base 1, an L-shaped mounting seat 2 fixedly connected to the top of the base 1, a connecting shaft 3 fixedly connected to the middle of the top of the base 1, a fixed sleeve 4 fixedly connected to the top of the connecting shaft 3, a rotating sleeve 5 sleeved on the outside of the fixed sleeve 4, a transmission shaft 6 fixedly connected to the middle of the top of the rotating sleeve 5, a drive motor 7 fixedly connected to the top of the transmission shaft 6, and the drive motor 7 embedded in the L-shaped mounting seat 2; six flipping seats 10 are provided on the outside of the fixed sleeve 4, and multiple magnetic grooves 11 are opened on the side ends of the six flipping seats 10; a flipping mechanism is provided inside the fixed sleeve 4 to flip the flipping seats 10; a magnetic attraction mechanism is provided at the magnetic grooves 11 to attract screws; a screw unloading rack 21 is provided on one side of the rotating sleeve 5; a support frame 22 is provided at the front of the base 1; and a conveyor belt 23 is provided inside the support frame 22.

[0021] By setting up a flipping mechanism and a magnetic attraction mechanism, the flipping mechanism can rotate 180° when one of the flipping seats 10 rotates to the first opening slot 15, the connecting slot 16 and the second opening slot 17 after adsorbing some screws during the continuous rotation of the rotating sleeve 5 driven by the drive motor 7. The flipping seat 10 can be automatically flipped by the flipping mechanism, and at the same time, the screws in the magnetic attraction slot 11 are stably adsorbed and released by the magnetic attraction mechanism. This realizes the automatic flipping and posture adjustment of screws during the conveying process. The structure is compact and the action is smooth. No additional clamping or robotic arm operation is required, which effectively simplifies the process and improves sorting efficiency.

[0022] Please refer to Figures 1 to 4. Both the fixed sleeve 4 and the rotating sleeve 5 are open at the bottom. The external dimensions of the fixed sleeve 4 are smaller than the internal dimensions of the rotating sleeve 5. The cross-sections of the fixed sleeve 4 and the rotating sleeve 5 are circular, and the centers of the cross-sections of the fixed sleeve 4 and the rotating sleeve 5 coincide.

[0023] Please refer to Figures 3 to 6. The outer end of the rotating sleeve 5 has six through holes 8, which correspond to the positions of six flip seats 10. A coil roller 9 is rotatably connected inside the through holes 8. One end of the coil roller 9 is connected to its corresponding flip seat 10, and the other end of the coil roller 9 is fixedly connected to an arc plate 12. The arc plate 12 is located between the fixed sleeve 4 and the rotating sleeve 5. Two symmetrically arranged sliding rods 13 are fixedly connected to one end of the arc plate 12 near the fixed sleeve 4. Two L-shaped connecting rods 14 are fixedly connected to the top wall of the inner wall of the fixed sleeve 4. The other end of the L-shaped connecting rods 14 is connected to the inner side wall of the fixed sleeve 4. The front and rear ends of the fixed sleeve 4 are provided with a first opening groove 15, a connecting groove 16, and a second opening groove 17.

[0024] The controller controls the drive motor 7 to work. The drive motor 7 can drive the rotating sleeve 5 to rotate counterclockwise. The rotating sleeve 5 can drive the flipping seat 10 and the coil roller 9 to rotate together. The coil roller 9 drives the sliding rod 13 at one end of the arc plate 12 to slide at the bottom edge of the fixed sleeve 4. When the sliding rod 13 slides to the first opening groove 15, the sliding rod 13 begins to flip and slides out from the second opening groove 17, completing a flipping operation.

[0025] Please refer to Figures 4 and 6. There are six sets of through holes 8 and coil rollers 9. The central axes of through holes 8 and coil rollers 9 coincide. Polished layers are provided at the contact points of sliding rod 13 with fixed sleeve 4, first opening groove 15, connecting groove 16, and second opening groove 17. By providing polished layers at the contact points of sliding rod 13 with fixed sleeve 4, first opening groove 15, connecting groove 16, and second opening groove 17, the frictional resistance of sliding rod 13 during movement is effectively reduced, wear is reduced, the service life of the mechanism is extended, and the flipping action is made smoother.

[0026] The first opening groove 15, the connecting groove 16, and the second opening groove 17 are connected. The cross-sections of the first opening groove 15, the connecting groove 16, and the second opening groove 17 are inverted Y-shaped. By connecting the first opening groove 15, the connecting groove 16, and the second opening groove 17, a continuous guide track is formed, allowing the sliding rod 13 to pass through each groove segment in sequence according to a predetermined trajectory. This precisely controls the flipping seat 10 to achieve a 180° flip at different positions, ensuring the accuracy and consistency of the flipping action.

[0027] Please refer to Figures 2 and 5. A pressure rod 18 is fixedly connected to the outer end of the coil roller 9. The pressure rod 18 is located outside the rotating sleeve 5. Six power switches 19 are embedded in the outer end of the rotating sleeve 5. The six power switches 19 correspond to the positions of the six coil rollers 9. The cross-section of the power switch 19 is arc-shaped. A notch 20 is opened at the bottom of the power switch 19. The arc-shaped power switch 19 is arranged around the outer circumference of the coil roller 9. The edge of the power switch 19 is rounded.

[0028] When the rotating sleeve 5 rotates, the pressure rod 18 rotates with the coil roller 9. When it contacts the energized switch 19, the coil roller 9 is energized, generating a magnetic force to attract the screw. When the pressure rod 18 rotates to the notch 20 position, the circuit is disconnected, the coil roller 9 is demagnetized, and the screw is released. This realizes automatic control of magnetic attraction and release without the need for additional sensors or control systems. Moreover, the edge of the energized switch 19 is rounded, which allows the pressure rod 18 to smoothly contact and leave the energized switch 19 during the rotation of the coil roller 9. This avoids jamming or impact caused by sharp edges and ensures the continuity and stability of the magnetic attraction mechanism.

[0029] Working Principle: In use, the automatic screw sorting machine's flipping mechanism first sorts the screws using a vibratory feeder, then conveys them via a screw unloading rack 21. Simultaneously, the drive motor 7 is activated, driving the rotating sleeve 5 to rotate continuously around the connecting shaft 3 outside the fixed sleeve 4 via the transmission shaft 6. Six coil rollers 9 are rotatably connected to the rotating sleeve 5 through through holes 8. Each coil roller 9 has a flipping seat 10 fixedly connected to one end and an arc-shaped plate 12 fixedly connected to the other end. A sliding rod 13 is provided on the arc-shaped plate 12. During the rotation of the rotating sleeve 5, it drives the flipping seat 10 and the coil rollers 9 to rotate together. The coil rollers 9 drive the sliding rod 13 at one end of the arc-shaped plate 12 to slide at the bottom edge of the fixed sleeve 4. When the sliding rod 13 slides to the first opening groove 15, it begins to flip and slides out through the second opening groove 17, completing the process. The device performs a flipping operation. Simultaneously, multiple magnetic grooves 11 are provided on the side of the flipping seat 10. When the flipping seat 10 passes the screw unloading rack 21, the pressure rod 18 on the coil roller 9 contacts the energized switch 19, energizing the coil roller 9 to generate magnetic force. This magnetic force attracts the screws from the screw unloading rack 21 into the magnetic grooves 11. As the rotating sleeve 5 continues to rotate, the flipping seat 10 completes the flipping under the action of the flipping mechanism, adjusting the screws to the desired posture. When the flipping seat 10 rotates above the conveyor belt 23, the pressure rod 18 enters the notch 20 position, de-energizing the coil roller 9. The screws fall onto the conveyor belt 23 under gravity and are transported to the next process. This device achieves automatic screw attraction, flipping, and release without the need for additional clamping mechanisms. The actions are continuous and efficient, effectively improving the automation level and work efficiency of screw sorting, and is easy to use.
