Automatic screw locking machine

Abstract

The invention belongs to the technical field of screw locking, and discloses an automatic screw locking machine. The automatic screw locking machine comprises a locking mechanism, a material attracting mechanism, a feeding mechanism and a transferring mechanism. The locking mechanism comprises a torsion bar. The material attracting mechanism comprises a rotating disc and a plurality of screwdriver bits, wherein the screwdriver bits are arranged on the rotating disc in a penetrating manner and are evenly and circumferentially arranged around the center axis of the rotating disc, the rotating disc can rotate around the center axis of the rotating disc, the screwdriver bits can attract screws, and the torsion bar can rotate and press the screwdriver bits downwards. The feeding mechanism comprises a material disc, wherein the material disc can contain a plurality of screws, the screws correspond to the screwdriver bits in a one-to-one mode. The transferring mechanism enables the screwdriver bits to have a first working position where the screwdriver bits are located above the feeding mechanism to attract the screws and a second working position where the screwdriver bits can lock the screws. Due to the fact that the material attracting mechanism can attract and lock multiple screws in the process that the transferring mechanism goes back and forth once between the first working position and the second working position, the working efficiency of the automatic screw locking machine is improved, and the productivity is greatly improved.

Description

technical field [0001] The invention relates to the technical field of screw locking, in particular to an automatic screw locking machine. Background technique [0002] In the assembly process of machinery, electrical appliances and other products, it is often necessary to perform various locking screw operations. The traditional method is to use a manual screwdriver to lock the screw. However, this inefficient manual operation can no longer meet the needs of modern mass production and mechanical automation. Therefore, people have developed a screw lock machine. Screws and locking screws can be automatically conveyed, which greatly improves production efficiency and meets the needs of modern mass production and assembly. Most of the existing screw machines use automatic air-blowing pipes for feeding, but the automatic air-blowing pipes have requirements for the length-to-diameter ratio of the screws. For screws with an length-to-diameter ratio greater than or equal to 1.4, ...

Problems solved by technology

The traditional method is to use a manual screwdriver to lock the screw. However, this inefficient manual operation can no longer meet the needs of modern mass production and mechanical automation. Therefore, people have developed a screw lock machine. It can automatically convey screws and lock screws, which greatly improves production efficiency and meets the needs of modern mass production and assembly

Most of the existing screw machines use automatic air-blowing pipes for feeding, but the automatic air-blowing pipes have requirements for the length-to-diameter ratio of the screws. For screws with an length-to-diameter ratio greater than or equal to 1.4, air-blown pipes are used for screw feeding. Short screws with an aspect ratio less than 1.4 are generally fed by adsorption to prevent the short screws from turning over when the automatic blowing pipeline is used, which will cause the screw locking machine to fail to complete the screw locking action.

[0003] In the prior art, the screw locking machine includes a batch head and a feeding mechanism. The batch head can move to the feeding mechanism to absorb the screws, and then move to the top of the workpiece with screw holes to lock the screws. When multiple screw holes are set on the workpiece , that is, when the screw lock machine needs to lock multiple screws, the bit head of the screw lock machine needs to move back and forth between the feeding mechanism and the workpiece, repeatedly absorbing screws and locking screws, and a lot of time is wasted in absorbing screws and locking On the distance between the screws, the working efficiency of the screw locking machine is low, which reduces the production capacity
