Description

Technical Field

[0001] This utility model relates to the technical field of screw conveying equipment, specifically a vibratory feeder screw conveying structure. Background Technology

[0002] In modern industrial automated production, the automatic feeding and conveying of screws is an indispensable link. Vibratory feeder screw conveying structures, with their efficient and stable feeding characteristics, have become the preferred choice for many manufacturing enterprises. Traditional vibratory feeder screw conveying structures mainly consist of components such as a hopper, chassis, vibratory motor, and spiral track.

[0003] Chinese Patent Publication No. CN214731998U discloses a vibratory feeder screw feeding structure, including a screw positioning fixture, a vibratory feeder, a guide rail, and a stop device. The screw positioning fixture includes a base, a turntable, and a drive device. The turntable is mounted on the base and is driven by the drive device to rotate around the central axis of the base. The upper surface of the turntable has several screw grooves matching the shape of the screws. The two ends of the guide rail are respectively connected to the base and the output end of the vibratory feeder. A drop slide is provided at the connection between the base and the guide rail. The drop slide is inclined, and the outer wall of the screw groove has a clearance notch that connects to the lower end of the drop slide. The output end of the vibratory feeder is higher than the upper end of the drop slide, so that the guide rail is inclined. The stop device has a stop plate above the drop slide to prevent the screws from sliding down. The stop plate moves up and down to release the screws. This utility model uses a vibratory feeder and a turntable to perform screw sorting and single-point positioning feeding in two stages, which is convenient for subsequent equipment to pick up.

[0004] In the existing technology, the use of a vibratory feeder screw feeding structure involves separate feeding of the vibratory feeder and the turntable. The screws need to be sorted and fed to the guide rail by the vibratory feeder first, and then positioned by the rotation of the turntable, which involves many steps. Therefore, we have made an improvement and proposed a vibratory feeder screw feeding structure. Utility Model Content

[0005] The purpose of this utility model is to address the problem of low efficiency caused by the numerous steps in the current vibratory feeder screw feeding structure.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A vibratory feeder screw feeding structure, driven by dual vibration sources, enables continuous screw feeding and orientation within the same track system, reducing waiting time in intermediate stages and improving efficiency, thereby addressing the aforementioned problems.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In the scheme of this application:

[0018] (1) Through the coordinated drive of dual vibration sources and multi-level track optimization design, the first vibration motor provides basic power and the second vibration motor assists in orientation. The combination of the two reduces material jamming and achieves efficient, accurate and stable screw conveying. In the track system, notches, guide grooves and protrusions cooperate with each other to classify, screen, limit and adjust the attitude of screws, effectively improve the feeding accuracy and meet the high precision requirements of automated assembly scenarios.

[0019] (2) The tilt angle of the chassis is monitored in real time by the tilt sensor at the bottom of the chassis, and the chassis can be quickly restored to a horizontal state by coordinating the adjustment of the height of multiple support feet. This avoids the screws from sliding off the track, accumulating or jamming due to the tilt of the equipment, thus ensuring the feeding accuracy and stability. Attached Figure Description

[0031] Example 1: Please refer to the appendix of the instruction manual. Figure 1-4A vibratory feeder screw delivery structure includes a housing 1. A base 2, a lower track 4, and an upper track 5 are slidably connected inside the housing 1. The base 2 and the lower track 4 are fixedly connected. A first vibration motor 3 is embedded in the bottom of the inner wall of the housing 1. The output end of the first vibration motor 3 is fixedly connected to the base 2. Several notches 7 are provided on the lower track 4. Guide grooves 8 are provided on both sides of the inner wall of the upper track 5. A connecting track 6 is provided between the lower track 4 and the upper track 5. Both sides of the connecting track 6 are fixedly connected to the lower track 4 and the upper track 5, respectively. Bases 10 are fixedly installed on both sides of the inner wall of the housing 1. A second vibration motor 11 is embedded in the top of each of the two bases 10. Vibration transmission rods 12 are fixedly installed at the output ends of the two second vibration motors 11. The ends of the two vibration transmission rods 12 away from the second vibration motors 11 are fixedly connected to the lower track 4. Several protrusions 9 are fixedly installed at the bottom of the inner wall of the lower track 4.

[0032] In this embodiment of the utility model, after the device is started, the first vibration motor 3 starts to work, and its output end drives the chassis 2 to vibrate. Since the chassis 2 is fixedly connected to the lower track 4, the lower track 4 vibrates. The screw is placed on the lower track 4. Under the action of vibration, the screw begins to move on the lower track 4. The protrusion 9 at the bottom of the inner wall of the lower track 4 can change the direction of movement of the screw, so that the screw continuously adjusts its posture on the track.

[0033] In this embodiment of the invention, the first vibration motor 3 drives the chassis 2 and the lower track 4 to vibrate, and the second vibration motor 11, through the vibration transmission rod 12, provides additional vibration to the lower track 4, which enables the screw to move quickly on the track, greatly improving the screw conveying efficiency.

[0034] Example 2: Please refer to the appendix of the instruction manual. Figure 1-4 In a preferred embodiment of the present invention, one-way guide plates 14 are fixedly installed on both sides of the inner wall of the connecting track 6, and the bottom of several one-way guide plates 14 are fixedly connected to the bottom of the inner wall of the connecting track 6.

[0035] An inclined track 13 is provided inside the housing 1, and the inclined track 13 is fixedly connected to the lower track 4.

[0036] The spacing between the gaps 7 on the lower track 4 decreases from bottom to top. Inclined guide grooves are provided on the inner wall of the lower track 4 and located at the gaps 7. The groove width is 1.5 times the diameter of the bolt rod and the groove depth is 0.5 times the height of the bolt head.

[0037] A rubber pad is fixedly installed on the outside of the chassis 2, and a reinforcing rib 15 is provided inside the chassis 2.

[0038] Several servo motors 17 are fixedly installed inside the housing 1. Each of the output ends of the servo motors 17 is fixedly installed with a threaded rod 18. The threaded rods 18 pass through the bottom of the housing 1 and are rotatably connected to it. Support feet 19 are threadedly connected to the outside of the threaded rods 18. Several tilt sensors 16 are embedded in the bottom of the chassis 2.

[0039] A transparent window 20 is provided on the housing 1, and a controller 21 is embedded on one side of the housing 1. The controller 21 is electrically connected to the first vibration motor 3, the second vibration motor 11, the tilt sensor 16 and the servo motor 17.

[0040] In this embodiment of the utility model, as the screw moves upward on the lower track 4, when it reaches the position of the notch 7, due to the inclined guide groove provided on the inner wall of the notch 7, the groove width is 1.5 times the diameter of the bolt shank, the groove depth is 0.5 times the height of the bolt head, and the spacing of the notches 7 decreases from bottom to top, the screw will enter the connecting track 6 through the notch 7 in a specific posture under the combined action of gravity and vibration.

[0041] The one-way guide plates 14 on both sides of the inner wall of the connecting track 6 ensure that the screw can only move in one direction and prevent the screw from flowing back. After passing through the connecting track 6, the screw enters the upper track 5. The guide grooves 8 on both sides of the inner wall of the upper track 5 further guide and limit the screw, so that the screw can move stably on the track.

[0042] The second vibration motor 11 applies additional vibration to the lower track 4 through the vibration transmission rod 12, further promoting the movement and posture adjustment of the screw, ensuring that the screw can pass smoothly through each track.

[0043] The inclined track 13 is connected to the lower track 4. The screws screened by the notch 7 will eventually slide out through the inclined track 13 to prevent them from falling onto the lower track 4.

[0044] The tilt sensor 16 at the bottom of the chassis 2 monitors the tilt angle of the chassis 2 in real time and transmits the data to the controller 21. When the tilt angle does not meet the set requirements, the controller 21 controls the servo motor 17 to work. The servo motor 17 drives the threaded rod 18 to rotate, thereby adjusting the height of the support foot 19 to keep the chassis 2 level and ensure the stability of screw delivery.

[0045] In this embodiment of the invention, the protrusion 9 at the bottom of the inner wall of the lower track 4 and the inclined guide groove of a specific size set on the inner wall of the notch 7 enable the screw to continuously adjust its posture during movement, ensuring that the screw enters the connecting track 6 and the upper track 5 in the correct posture, providing accurate screw position for subsequent automated assembly and improving assembly accuracy.

[0046] The unidirectional guide plate 14 connecting the track 6 effectively prevents screw backflow and ensures the directionality of screw conveying; the guide groove 8 of the upper track 5 provides precise guidance and limit for the screw, further ensuring that the screw moves stably on the track, avoiding problems such as screw jamming and falling, and improving the stability and reliability of conveying.

[0047] The rubber pads on the outside of the chassis 2 can absorb vibration and reduce the impact of vibration on the equipment and the surrounding environment; the reinforcing ribs 15 inside the chassis 2 enhance the structural strength of the chassis 2, making the entire equipment stable under long-term vibration operation and extending the service life of the equipment.

[0048] The tilt angle of the chassis 2 is monitored in real time by the tilt sensor 16. The automatic adjustment system composed of the controller 21 and the servo motor 17 can automatically adjust the level of the equipment, ensuring that the screw conveying process is not affected by the tilt of the equipment, thus improving the adaptability and stability of the equipment and reducing the cost and time of manual debugging.

[0049] The transparent window 20 on the housing 1 allows operators to observe the screw conveying status in real time; the controller 21 integrates the control of the first vibration motor 3, the second vibration motor 11, the tilt sensor 16 and the servo motor 17, realizing intelligent control of the equipment. Operators can flexibly adjust the equipment parameters according to actual production needs, improving the flexibility and convenience of production; at the same time, heat dissipation holes are opened on the device to cooperate with several motors.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
