[0002] A fastener is a mechanical element used to connect and fasten two or more parts. During the fastener assembly process, mechanical transmission, pneumatic or electric methods are required to take the fasteners out of the storage device one by one and transport them to the designated location.

[0003] Existing fastener feeding mechanisms often suffer from excessively high feed rates, leading to a large influx of fasteners into the conveying channel within a short period of time. If the channel's conveying capacity is limited, fasteners can accumulate within the channel, causing blockage. This not only interrupts the production process but also requires time and manpower to clean up, severely impacting production efficiency. In particular, in vibrating plate feeding systems, excessive fasteners can become lodged in the vibrating track, causing the plate to malfunction. Therefore, a fastener feeding mechanism has been proposed. Utility Model Content

DETAILED DESCRIPTION

[0033] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 1-Figure 3 The present invention provides an embodiment of a fastener feeding mechanism, comprising a platform 1. Platform 1 serves as the supporting foundation for the entire fastener feeding mechanism, providing a stable mounting platform for other components. A vibrating plate 2 is mounted in the middle of the upper portion of platform 1. Vibrating plate 2 vibrates at a specific frequency, causing fasteners to move in an orderly manner along a pre-set track. Its function is to organize fasteners from a chaotic state into an orderly arrangement for subsequent feeding and processing. The vibration of the vibration plate 2 can adjust the frequency and amplitude to adapt to fasteners of different sizes and shapes, thereby improving the versatility of feeding. A support frame 3 is installed on the right part of the machine platform 1, and the support frame 3 plays the role of supporting and fixing the storage box 4 and other related components. The upper side of the support frame 3 is fixedly connected to the storage box 4, and the storage box 4 is used to store a large number of fasteners, providing a continuous supply for the feeding process. A driving assembly is installed on the front side of the storage box 4, and the driving assembly provides power for the feeding assembly so that it can reciprocate in the storage box 4 to realize the transportation of the fasteners. The feeding assembly is installed inside the storage box 4. The feeding assembly is the core component of the fastener feeding mechanism. It is responsible for transporting the fasteners in the storage box 4 one by one to the inside of the vibration plate 2. A feeding plate 21 is fixedly connected to the bottom of the storage box 4. The feeding plate 21 is the channel for transporting the fasteners from the storage box 4 to the inside of the vibration plate 2. A cleaning assembly is installed in the middle of the support frame 3. The function of the cleaning assembly is to clean the fasteners during the feeding process, remove dust and impurities, and improve the quality of the fasteners.

[0035] Reference Figure 1-Figure 3 The feeding assembly includes two slide bars 6, which are installed on the front and back sides of the storage box 4. The slide bars 6 provide a stable guide for the feeding process. The outer side of the slide bars 6 is slidably connected to a slider 7. Under the action of the drive assembly, the slider 7 can slide back and forth along the slide bar 6, thereby driving the connecting plate 8 and the conveying plate 9 to move. The two sliders 7 are fixedly connected to the opposite side of the connecting plate 8. The connecting plate 8 is used to connect and transmit power. When the sliders 7 move, the connecting plate 8 can synchronize the movement of the two sliders 7 so that the two conveying plates 9 can maintain consistent movement. Two conveying plates 9 are fixedly connected between the bottoms of the two connecting plates 8. The conveying plates 9 directly contact the fasteners and are responsible for pushing the fasteners out of the storage box 4 and transporting them to the designated position. The outer side of the slide bars 6 is covered with a spring 10. When the slider 7 moves forward under the push of the drive assembly, the spring 10 is compressed and stores energy. When the force of the drive assembly disappears, the spring 10 releases energy, pushing the slider 7 upward, realizing the reciprocating motion of the feeding assembly.

[0036] Reference Figure 1-Figure 3The driving assembly includes a servo motor 11, which is installed in the middle of the front side of the support frame 3. The servo motor 11 has the characteristics of high precision, fast response, and good stability. It can accurately control the movement speed and position of the feeding assembly. The output end of the servo motor 11 is fixedly connected to an eccentric wheel 12, which converts the rotational motion of the servo motor 11 into the reciprocating linear motion of the feeding assembly.

[0037] Reference Figure 4 、 Figure 5 and Figure 7 The cleaning assembly includes a cylinder 15, an air blowing port 22 and a dust collecting plate 23. The cylinder 15 is installed in the middle of the support frame 3 through a bracket. The cylinder 15 is the main component of the cleaning assembly. It is installed in the middle of the support frame 3 through a bracket. The position is stable and reliable. The piston 16 is slidably connected inside the cylinder 15. The piston 16 slides up and down in the cylinder 15, compressing the air and delivering it to the air blowing port 22 and the dust collecting plate 23 through a one-way valve 17 and a pipe 18. The upper side of the piston 16 is fixedly connected to a connecting rod 14. The connecting rod 14 connects the piston 16 to the feeding assembly so that the piston 16 can move up and down under the drive of the feeding assembly. Two one-way valves 17 are fixedly connected to the bottom of the cylinder 15. The one-way valve 17 controls the flow direction of the air to ensure that the air It can only flow from the cylinder 15 to the pipe 18, but not in the opposite direction. The bottom of the one-way valve 17 is fixedly connected to the pipe 18. The pipe 18 transports the compressed air from the cylinder 15 to the blowing port 22 and the dust collection plate 23. A filter assembly is installed on the outside of the right pipe 18. The blowing port 22 is set on the left inner wall of the feeding plate 21. The blowing port 22 blows out the compressed air to purge the fasteners and remove dust and impurities on their surfaces. The dust collection plate 23 is set on the right inner wall of the feeding plate 21. The dust collection plate 23 sucks in the dust and impurities generated by the blowing through negative pressure, and discharges them after being filtered by the filter assembly. The filter assembly filters the air inhaled by the dust collection plate 23, removes the dust and impurities therein, and prevents them from entering the cylinder 15 and polluting the environment.

[0038] Reference Figure 6 The filter assembly includes a filter box 19, which is arranged in the middle of the right pipe 18. The filter box 19 is the main component of the filter assembly and is installed in the middle of the right pipe 18 to filter the air inhaled by the dust collection plate 23. The filter box 19 is slidably connected to the inside of the filter box 19. The filter screen 20 is the core component of the filter assembly, which can effectively filter dust and impurities in the air.

[0039] Reference Figure 1-Figure 3 A feed port 5 is installed on the upper side of the storage box 4. The feed port 5 is the channel for the fasteners to enter the storage box 4. A guide plate 13 is installed on the bottom wall of the storage box 4. The guide plate 13 guides the fasteners in the storage box 4 to ensure that the fasteners can smoothly enter the conveying plate 9.

[0040] Reference Figure 3The eccentric wheel 12 fits in with the left slider 7, and the slider 7 is pushed to slide on the slide rod 6 through rotation. The outer side of the conveying plate 9 is slidably connected to the bottom wall of the storage box 4, which makes it easy to push the fasteners out of the storage box 4 to improve the feeding efficiency.

[0041] Reference Figure 3-Figure 5 The upper side of the connecting rod 14 passes through the top of the cylinder 15 and is fixedly connected to the bottom of the rear slider 7, so that the piston 16 can move up and down driven by the feeding assembly. A handle is fixedly connected to the top of the filter screen 20. The setting of the handle makes it easy for the operator to remove the filter screen 20 from the filter box 19 for cleaning and replacement.

[0042] Reference Figure 5-Figure 7 The left side pipe 18 is connected between the end away from the cylinder 15 and the blowing port 22. The left side pipe 18 transports the compressed air in the cylinder 15 to the blowing port 22 to purge the fasteners. The right side pipe 18 is connected between the end away from the cylinder 15 and the dust collection plate 23. The right side pipe 18 transports the air sucked in by the dust collection plate 23 to the filter box 19 for filtration.

[0043] Working principle: When fasteners need to be fed, a large amount of fasteners are poured into the storage box 4. Then, the vibration disk 2 and the servo motor 11 are energized and started. The servo motor 11 starts to rotate, driving the eccentric wheel 12 to rotate. The rotation of the eccentric wheel 12 squeezes the slider 7 through its own protruding part, causing the slider 7 to slide downward. The downward sliding of the slider 7 drives the connecting plate 8 to slide downward, further driving the conveying plate 9 to slide downward while squeezing the spring 10. When the conveying plate 9 slides downward, the fasteners inside the storage box 4 will pass through the upper side of the conveying paper feed plate 21 under the action of the conveying plate 9, and are further conveyed to the inside of the paper conveying vibration disk 2 through the feed plate 21.

[0044] When the slider 7 slides downward, it will also drive the connecting rod 14 to slide. The sliding of the connecting rod 14 drives the piston 16 to slide. The piston 16 slides, increasing or decreasing the air pressure at the bottom of the cylinder 15. When the air pressure inside the cylinder 15 decreases, the air pressure inside the cylinder 15 will be transported to the air outlet 22 through the action of the left one-way valve 17 and the pipe 18. At this time, the fastener that has fallen on the feeding plate 21 is blown. When the protruding part of the eccentric wheel 12 no longer squeezes the slider 7, the slider 7 will be reset by the elastic force of the spring 10, further driving the connecting rod 14 to reset, thereby increasing the air pressure at the bottom of the cylinder 15, and through the action of the right one-way valve 17 and the pipe 18, the dust brought by the blowing will be adsorbed, and the dust and impurities will be blocked by the filter screen 20 inside the filter box 19.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
