Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of screw feeding, and particularly relates to a multifunctional screw feeding system. BACKGROUND

[0002] In industrial automatic assembly, the screw fastening link is crucial. The traditional manual operation and the existing automatic equipment still have deficiencies in efficiency, stability and flexibility, especially difficult to adapt to the production mode of multiple varieties and small batches, often causing downtime due to screw type change, material jam and the like, affecting the overall equipment efficiency. The screw feeding equipment on the market currently arranges multiple independent feeding modules in parallel, each module is preloaded with a type of screw, and the execution mechanism is switched to dock different discharge ports when the type needs to be changed.

[0003] For example, the Chinese patent with the application number "201720713893.3" discloses a screw distribution and feeding mechanism, which comprises a support, a vibration feeding disc, two feeding tracks, a distribution mechanism and a feeding mechanism. The feeding mechanism is fixed on the support and comprises two guide pipes and a blowing interface communicated with each guide pipe. The distribution mechanism is fixed above the feeding mechanism and comprises a distribution plate, a sealing plate and a driving member. Two inclined grooves are formed along the edge of the distribution plate, and the width of each inclined groove is sufficient for a screw to pass through without falling. The non-opening end of each inclined groove is connected with two round holes arranged in the middle of the distribution plate for screw falling. The sealing plate is horizontally fixed below the distribution plate through the connecting blocks at both ends, and two through holes are formed in the sealing plate to correspond to the round holes for screw falling. The output end of the driving member is connected with the connecting blocks to drive the distribution plate to move the inclined grooves back and forth at the end of the feeding track. When the inclined groove is docked with the feeding track, each through hole and the upper end of the corresponding guide pipe are coaxial and opposite to each other and are in communication with each other. The distribution plate, the sealing plate, the guide pipe and the blowing interface are all fixed on the screw docking plate. This type of screw feeding equipment needs to add a complete feeding module when increasing the type of screws, and the hardware cost and space occupation increase substantially. The physical switching process is time-consuming and cannot realize instantaneous type change. Each module still uses the traditional vibration disc and guide rail, and the inherent risks such as material jamming and screw flipping still exist. There is a lack of real-time monitoring and prediction ability for the amount, state and failure of the material. The essence is still mechanical stacking rather than intelligent integration. If a multifunctional screw feeding system with simple structure, scalable and movable arrangement, and integrated dust cleaning function can be designed, the above problems can be solved. SUMMARY
