Automatic screw locking machine

Abstract

The embodiment of the invention discloses an automatic screw locking machine which is used for avoiding the situation that the screw position is inclined, and locking is failed due to the fact that the screw hole cannot be aligned. The automatic screw locking machine has no requirement for the magnetic force feature of screws, and various types of screws can be locked on a locked object. The automatic screw locking machine comprises an electric screw driver, an elastic clamp head, a clamping pneumatic claw, a locking hole sliding platform, a downwards-pressing air cylinder, and a program controller, wherein the elastic clamp head is arranged on the electric screw driver, the head of the elastic clamp head is provided with a clamping position for being clamped with a screw head of a screw in a matched mode, and the clamping position is used for fixing the screw to the elastic clamp head by clamping the screw head; the clamping pneumatic claw is used for clamping a screw rod of the screw to fix the screw; the locking hole sliding platform is used for conveying a screw hole required to be locked currently in the locked object to the position below the elastic clamp head by moving the locked object; the downwards-pressing air cylinder is used for driving the electric screw driver and the elastic clamp head on the electric screw driver to move downwards; the program controller is used for controlling the electric screw driver, the clamping pneumatic claw, the downwards-pressing air cylinder and the locking hole sliding platform through a preset operation process.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an automatic screw locking machine. Background technique [0002] At present, screws are widely used, such as circuit boards, peripheral housings, internal structures of electronic equipment, etc., all of which require a large number of screws for structural fixing and locking. In order to improve the efficiency of production, the automatic locking screw machine came into being. [0003] The general practice of the current automatic screw locking machine is: control all the work processes through the program controller on the automatic locking screw machine, first use the magnetic screwdriver on the electric screwdriver to pick up the screw, and then send the screw hole that needs to be locked currently to the locked object. To the bottom of the magnetic screwdriver, the electric screwdriver is used to rotate and tighten the screw to the screw hole to complete the locking of a screw hol...

AI Technical Summary

Problems solved by technology

[0004] However, it is not reliable to use a magnetic screwdriver to pick up screws. With the long-term use of the magnetic screwdriver, the magnetic force of the magnetic screwdriver will gradually weaken, and the adsorption effect on the screw will become weaker and weaker, and the screw will appear on the magnetic screwdriver. The upper position is tilted and cannot be aligned with the screw hole, resulting in locking failure

Moreover, the magnetic screwdriver does not work for screws that are not affected by magnetism (such as stainless steel screws), and cannot lock the screws that are not affected by magnetism to the locking object
