Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screw locking, in particular to a screw feeding device. Background Art
[0002] In the field of feeding of existing automatic screw locking machines, generally multiple types of screws are mixed and used on the production line, and different products require replacement of screws with different length specifications. The product changeover time on the production line is very short, usually only a few minutes. Therefore, it is required that the product changeover time of the equipment must be fast and the replacement must be convenient.
[0003] If product changeover is required, either multiple sets of feeders are configured for different screws, or the screws in the feeder are cleaned out. The first method requires sufficient space to install the feeders, and the movement mechanism of the locking mechanism or the coverage range of the robot needs to be large enough. In most cases, this method cannot be adopted. For the second method, since the square feeder is an integral structure and cannot be disassembled, cleaning the screws requires manual extraction or adsorption and removal with a magnetic rod, which is rather cumbersome and time-consuming. Moreover, it is easy to miss, resulting in mixed screws in production.
[0004] When the conveying channel on the linear vibrator is in use, a channel pressing plate needs to be set at a specific height to press the screws to prevent screw stacking during the conveying process, which may cause blockage. When cleaning and replacing screws during product changeover on the production line, the screws in the channel need to be removed together. At this time, either wait for the screws to slowly vibrate out through the vibrator (which takes a long time), or remove the pressing plate, clean it, and then reinstall and adjust the height, which is time-consuming and laborious.
[0005] When the screws fall into the conveying channel, some screws cannot accurately fall into the slots of the conveying channel, which will cause screw feeding blockage. Summary of the Utility Model
