Description

Technical Field

[0001] The utility model relates to the technical field of screw arranging structures, in particular to a screw arranging structure for an automatic screw locking machine. Background Art

[0002] At present, screws are widely used, such as circuit board components, peripheral housings, internal structures of electronic devices, etc., all of which require a large number of screws for structural fixation and locking. In order to improve production efficiency, automatic screw locking machines have come into being. The general practice of current automatic screw locking machines is: all work processes are controlled by the program controller on the automatic screw locking machine. First, the magnetic screwdriver on the electric screwdriver is used to suck up the screws, and then the screw holes that need to be locked on the locking object are sent to the bottom of the magnetic screwdriver. The screws are rotated and tightened to the screw holes by the electric screwdriver to complete the locking of a screw hole of the locking object. Then the above operation is repeated through the program controller until all the screw holes on the locking object are locked. However, in the process of locking the screws, the screws need to be extracted and then locked. Therefore, it is necessary to invent a screw sorting structure for an automatic screw locking machine.

[0003] At present, the publication number CN218908842U discloses an automatic screw sorting and feeding device, in which the screws to be sorted in the storage box slide down from the inclined surface into the storage tank, and then the lifting plate lifts the screws in the storage tank under the drive of the driving component and makes the screws slide onto the feeding conveying track for the first sorting, and then the vibrator is turned on, and the vibrator drives the feeding conveying track to produce a certain vibration, so that the screws on the feeding conveying track are sorted for the second time, and the screws will move forward along the feeding conveying track to feed, thereby realizing the sorting and feeding of the screws. Through the above design, the efficiency of sorting and feeding the screws is effectively improved, thereby improving the production efficiency of the product.

[0004] In order to solve the problem of screw arrangement in the screw locking machine, the existing technology adopts the method of vibrating and transmitting the screws through a vibrator to process them. However, the screws cannot be arranged in an orderly manner and the arrangement of the screws is not efficient enough, which leads to low subsequent work efficiency and inconvenience in screw arrangement.

The vibrator is used to arrange the screws in an orderly manner and move them along the track through vibration.
