Automatic assembly line unclamping system

Abstract

The invention relates to an automatic assembly line unclamping system. The system comprises a locking mechanism, an automatic unlocking device, an optoelectronic switch and a controller, wherein the locking mechanism comprises a guide rail, a sliding block and a spring; the unlocking device comprises an air cylinder, an electromagnetic valve, a push rod and a bracket; a pneumatic device of the air cylinder is connected with the controller through the electromagnetic valve; the optoelectronic switch transmits detection signals to the controller; the controller controls the electromagnetic valve to act; when the electromagnetic valve is energized, the air cylinder acts to enable the push rod to move and push the sliding block to move in the direction opposite to a workpiece, so as to unlock the workpiece; when the electromagnetic valve is de-energized, the air cylinder is restored, the push rod is separated from the sliding block, and the sliding block continuously locks the workpiece under the restoring force of the spring. The system realizes the linked automatic clamping and unclamping of the workpiece by a clamp, and when the clamp reaches a position, the unlocking device performs automatic unlocking on the clamp, so that the system is not only convenient to operate, but also ensures that the clamp can not be unlocked manually, and has a mistake proofing effect.

Description

technical field [0001] The invention relates to an automatic clamp release system for an assembly line. Background technique [0002] The fixture design has gone through three stages, the first stage is mechanical, the second stage is pneumatic, and the third stage is linkage automation. In the first stage, whether it is rotating, flipping or unlocking, the mechanical clamps rely on manual work, which increases the man-hours; the pneumatic clamps in the second stage are more convenient for employees to operate than the mechanical clamps, but manual unlocking is still required, which will also cause Increased working hours. The first two clamps can be manually unlocked, which cannot prevent mistakes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic clamp release system for an assembly line. After the system recognizes that the clamp has reached its position, the unlocking device receives a signal and...
