Welding wire speed regulation control system

Abstract

The invention relates to the technical field of welding equipment, and particularly relates to a welding wire speed regulation control system. The welding wire speed regulation control system comprises a rack, a wire reel, a guide block, a driving motor and a controller; the guide block is positioned at the upper part of the wire reel; a supporting block is arranged below the wire reel; a guide block is arranged on a path for withdrawing the welding wire to the wire reel; and the guide block, the supporting block, the guide block and lead screw pairs of the guide block, the supporting block and the guide block form a welding wire control system together with the driving motor and the controller. When the wire reel rotates to take back the welding wire, the welding wire is wound on the wirereel in a disordered manner, so that the wire feeding rate of the welding wire during reuse is influenced; therefore, through cooperation of the guide block, the supporting block and the guide blockwhich are arranged on the rack, the winding area, the winding strength and the initial winding angle of the welding wire during wire winding are limited, the problem that the welding wire is wound disorderly during wire winding of the wire reel is solved, and the conveying rate of the welding wire in subsequent use is stabilized.

[0002] In the welding operation of the manipulator, when changing the type of welding wire, the welding wire in the welding wire guide of the manipulator needs to be withdrawn to the wire reel, which often causes the welding wire on the welding wire reel to be entangled, causing the chaotic winding of the welding wire to change the wire feeding time when it is used again. The stable rate, which in turn affects the effect of wire welding

[0003] The existing welding wire speed control system generally provides parameter setting through the control part, and the driving part performs wire feeding drive under the control of the control part. The motor drives the driving wheel to rotate to provide power for wire feeding, and the driven wheel presses the welding wire into the wire feeding groove on the wire feeding wheel, increasing the friction between the welding wire and the wire feeding wheel, so that the welding wire can be sent out smoothly; Part of it is difficult to retract the welding wire on the wire reel in a regular manner, which makes it difficult to control the speed of the chaotically wound welding wire on the wire reel during subsequent use, which affects the welding effect

[0004] There are also some technical solutions for welding wire speed control systems in the prior art. For example, a Chinese patent with application number 2014101332659 discloses a welding wire speed control system, which uses the current of the armature winding of the printing motor to work in a discontinuous state Next, the sample-and-hold device is triggered by the synchronous pulse of the current-type pulse width modulation controller to collect the armature induced electromotive force at the time when the motor armature winding current is zero, so as to realize the precise feedback of the motor speed, and cooperate with a set of closed-loop speed regulation control system, thereby Ensure the stability of welding wire speed, and provide overcurrent fault protection for the system through the overcurrent shutdown function of the current-type pulse width modulation controller; however, this technical solution does not take into account the actual transmission status of the welding wire, especially when the wire is drawn The chaotic situation makes the technical solution not perfect
