An automatic screw locking machine is typical non-standard automation equipment. The automatic screw locking machine realizes the processes of automatic screw conveying, tightening, and inspection through various electric and pneumatic components. Next, let's take a look at the structure and working principle of the automatic screw locking machine. Here are some answers.
Here is the content list:
l The structure of the automatic screw locking machine.
l What is the working principle of an automatic screw locking machine?
The screw twisting machine is mainly composed of an automatic screw feeding machine, a locking mechanism, a power supply electrical box, and a positioning system. The automatic nail feeder is mainly responsible for the process of screw selection, arrangement, detection, material distribution, and transportation, and is an important link to replace manual screw removal. The locking mechanism is equipped with an electric batch, wind batch, or a servo motor, according to the program set to execute the screwing action, which completely replaces the manual operation. The screw counting machinecontrol system is mainly located in the electrical box. The input voltage is 220V. It usually adopts PLC control (or single-chip microcomputer) to realize the coordinated operation of automatic feeding and locking mechanism to realize the effect of automatic conveying and automatic locking of screws. The positioning system mainly ensures that the locking mechanism can accurately screw the screws into the screw holes of the product. The positioning is completed by multiple accessories such as workbenches, clamps, and jigs. It usually needs to be designed according to the appearance characteristics of the product.
The working principle of the screw feeder machine: the screwing machine includes an automatic screw alignment unit, an automatic screw conveying unit, an automatic screw tightening unit, and a detection unit during the locking process. The screw automatic alignment unit is mainly to arrange the loose screws neatly and output them individually. The aligning unit can be realized by a vibrating disc sorting mechanism or a rocker-type screw aligning mechanism.
First, the automatic screw conveying unit mainly conveys the entire row of screws individually to the working head of the screw tightening unit. Second, the automatic screw tightening unit includes a rotating power part and a screw introduction part. The common ways of introducing screws are air blowing and adsorption. Generally speaking, the air blowing type does not need to move the head back and forth because the work is continuous, so the overall efficiency is better than that of the adsorption type. However, the blow-in type itself is limited by the shape and aspect ratio of the screw, and not every type of screw is suitable for the blow-in type. Third, the detection unit includes the detection of screw leakage, floating lock, jamming, and other problems. The commonly used screwing machine should also include functions such as workpiece alignment and screw hole alignment. The most common are single-axis screw-tightening systems and multi-axis screw-tightening systems. Fourth, the single-axis screw tightening system can realize fully automatic screw tightening with the X-Y manipulator or transfer platform. The XY-table type screw driver machine is particularly suitable for screw locking of single workpieces with multiple holes and has high working efficiency.
