The automatic screw sorting unit mainly arranges loose screws neatly and outputs them separately. The alignment unit can be realized by a vibrating disk sorting mechanism or a rocker screw alignment mechanism.
The automatic screw conveying unit mainly conveys the whole row of screws to the working head of the screw tightening unit.
The automatic screw tightening unit comprises a rotating power part and a screw lead-in part. The common ways to introduce screws are blowing and sucking. Generally speaking, the overall efficiency of air blowing is better than that of adsorption, because it works continuously and does not need the head to move back and forth. However, the blowing type itself is limited by the shape and length-diameter ratio of the screw, and not every screw is suitable for blowing type. The detection unit includes the detection of screw lock loss, floating lock, material jam and other problems.
Figs. 3 and 4 show an air-blown automatic screw tightening unit.
The commonly used automatic locking screw machine should also include the functions of workpiece alignment and screw hole alignment.
The most common are single-axis screw tightening system and multi-axis screw tightening system.
Single-axis screw tightening system with X-Y manipulator or transfer platform can realize automatic screw tightening. XY table automatic locking screw machine is especially suitable for locking porous screws on a single workpiece, with high working efficiency.
Hand-held automatic locking screw machine, screw conveying and locking in one go, no need to hold screws by hand anymore. It greatly improves the production efficiency and saves labor. You can type as fast as you want. After each screw is punched, the machine will automatically send it to the batch nozzle. In addition to the hand-held automatic locking screw machine, there are also fully automatic screw machines on the market, which are controlled by computers. When the drawings are input into the computer, the tightening position can be controlled by the computer without manual operation. The following is the physical diagram of Xiehexin (CCB) screw machine: At present, in addition to the above-mentioned locking screw machine for locking a single screw, there are also multi-axis automatic locking screw machines on the market. Multi-spindle automatic locking screw machine can lock multiple screws at the same time, which can replace multiple workers; For example, 16 axis automatically locks the screw machine and locks the 16 screw at the same time, and the number of axes can be customized according to customer requirements; When each screw is locked.
Between about 2 s; The cost performance of the machine is the highest, and the cost can usually be recovered within one year.
