Automatic marking device, automatic marking welding system and its control circuit

Abstract

The invention provides an automatic marking device as well as an automatic marking welding system and a control circuit thereof. The automatic marking device comprises a marking machine, a worktable, a rotary pressing mechanism, a rotary unlading mechanism and a slideway; a marking needle of the marking machine is vertically flexible relative to the worktable; the rotary pressing mechanism comprises a rotary pressing cylinder vertically mounted on a support table; a piston of the rotary pressing cylinder is fixedly connected with a pressing arm realizing the rotary pressing action under the driving of the rotary pressing cylinder; the rotary cylinder of the rotary unloading mechanism is fixedly connected with a rotary arm and is provided with a rotary check part; the rotary stroke of the rotary arm is limited by the worktable and the check part; multiple electromagnets are arranged at the front end of the rotary arm; the slideway is adjacent to the rotary check part and positioned below the rotary stroke of the front end of the rotary arm, and an acute included angle is formed between the sliding upper surface of the slideway and the horizontal plane of the support table; and the opening of the slideway faces an assembly line. The automatic marking device as well as the automatic marking welding system and the control circuit thereof can automatically finish marking and unloading, and the work efficiency and the safety are improved as a dual-hand synchronous starting function is arranged.

Description

technical field [0001] The invention belongs to the field of auto parts processing equipment, and in particular relates to a device capable of automatically marking workpieces, and an automatic marking welding system including the automatic marking device and an automatic welding mechanism. In addition, The control circuit of the above-mentioned marking device and system is provided. Background technique [0002] In the existing technology, for the welding process of the sub-assembly of the rear sub-frame of the automobile, the spot welding of the upper and lower plates, the swing arm and the stabilizer bar is mainly carried out, such as figure 1 The workflow shown is: Employee A operates the marking machine to mark the workpiece. Since the marking station is 500 meters away from the welding station, employee B must transport the marked workpiece to employee C. , and the C employee will assemble the marked workpiece and the rear sub-frame. After the assembly is completed, t...

AI Technical Summary

Problems solved by technology

[0004] The present invention firstly provides an automatic marking device to solve the problem that the marking machine cannot realize automatic marking operation. The personnel place the workpiece to be marked on the workbench of the marking device and start the whole device. On-duty, marking and unloading are automatically completed, and personnel stay away during marking, which reduces or even avoids the damage to hearing caused by marking noise
