1.Brief introduction:
This automatic welding production line is upgraded based on the customer's existing five robotic welding stations. Mainly including manual assembly zone, KBK lifting device in the assembly zone, times speed conveying line, robotic loading and unloading line, middle bracket / light medium bracket robotic welding station, Rear lifting / light rear lifting robotic welding station, plate chain conveyor, Manual repair welding and cleaning zone, KBK lifting device in the manual repair welding and cleaning zone and the master control system.
2.Layout plan
3.The core technology:
1). Conveying line of robotic loading and unloading line
Mainly includes loading and unloading robot, robot control cabinet, robot teaching pendant, robot slide platform, compatibility automatic gripper, times speed chain logistics line, plate chain type of logistics line and control system.
2). The gripper adopts the structure design of the combination of electric permanent magnet and mechanical positioning, which can realize the versatility of grabbing different types of products of similar products. Since the magnet adopts an electric permanent magnet, the workpiece is suddenly powered off during the grasping process. Will not fall off. The overall structure is simple, safe and reliable.
3). Fixtures
the fixtures adopts automatic clamping and positioning, ability to match with handling robot information. Simple structure, convenient operation, high efficiency of assembly, and stable clamping force.
4).The times speed conveying line
Adopting double-layer times speed conveying, which is divided into upper and lower layers, and the self-returning is formed. The workpiece is positioned on the conveying chain plate by the location pin, and a secondary positioning mechanism is arranged in the transfer robot connection area to automatically complete the precise positioning of the chain plate.
5). Robot slide platform
Driven by servo motor + precision planetary reducer, free programming. It adopts domestic famous brand reducer, guide rail, slider, rack and pinion, which has high walking precision, meets welding requirements and has long service life.
6) The control electric of welding production line
The programmable program control system is adopted, and the main control part is controlled by PLC system. With "manual" and "automatic" optional features,
With: reservation, power on/off and indication, emergency stop button, with mechanical anti-collision, servo anti-collision, power status detection, interference field inspection and other functions.
4.Line advantage
1. Simple structure, convenient operation and high efficiency
2, It can achieve information interaction with the handling robot, high efficiency
3. Hi product qualification rate and consistency
4. The robot slide rail uses a fixed dust cover for the track, which has low failure rate and is not easy to damage.
5. Each control system can be freely programmed to meet the welding requirements of each workpiece.
6. With safety protection mechanism, automatic shutdown protection measures will be taken if the equipment is abnormal or the user operates abnormally.
