Problems solved by technology

[0003] After searching the documents of the prior art, it was found that Derwent's patent number is: 2002-754571[82], and the name is: Roll hemming method for joining panels, involving performing primary bending of outer panel flange , using primary roller having outer diameter larger than outer diameter of secondary roller), the patented technology reads as: the main roller (its outer diameter is larger than the secondary roller) installed on the robot arm completes the flanging of the outer plate, and the angle of the flanging It is determined by the slope angle of the main roller, and then the hemming is completed by the secondary roller. The advantage of this patented technology is that the worktable is fixed and the structure is simple, but

Example Embodiment

[0014] like Figures 1 to 4 As shown, the present invention includes: a six-degree-of-freedom parallel robot 1 , a rolling mechanism 2 , a rotary table 3 and a base 4 . The six-degree-of-freedom parallel robot 1 is fixed on the base 4 and connected to the rolling mechanism 2 through a flange plate, and the rotary table 3 is placed above the base 4 .

[0015] The six-degree-of-freedom parallel robot 1 is a six-degree-of-freedom platform mechanism. The six-degree-of-freedom parallel robot consists of six independently free telescopic rods. The six-degree-of-freedom parallel robot 1 is placed on the base 4 through the robot's fixed platform and the robot's The movable platform is connected with the rolling mechanism 2 through the flange plate, the rotary table 3 is placed on the base 4, the base 4 is placed at the bottom of the whole device, and the six-degree-of-freedom parallel robot 1 and the rotary robot are placed on both ends of the base 4. The worktable 3 is provided with...

Abstract

This invention relates to parallel-type robot system for edge covering with rotating table, comprising six-degrees freedom parallel-type robot attached with rolling machine and driving it to move roller along edge direction; rolling machine equipped with work piece and rotating table preparing the other side of work piece to be ready-covered edge. The invention has the advantages of high accuracy to improve edge-covering efficiency and quality.

Description

technical field [0001] The invention relates to a robot hemming system, in particular to a parallel robot hemming system with a rotary workbench, which is used in the field of automobile manufacturing. Background technique [0002] Hemming refers to folding the workpiece after flanging to 180°, which is a connection technology between the inner and outer plates of thin plate parts. There are mainly four kinds of hemming methods: manual hemming, hydraulic special hemming machine hemming, molded hemming and robot hemming. The production efficiency of manual hemming is low, and the product appearance quality is poor. Due to the limitation of its structure, the hemming action of hydraulic special hemming machine needs to be realized step by step, the door is prone to indentation, and the overall hemming quality is not high. One-time forming of molded hemming has the advantages of high production efficiency, good hemming quality and appearance, but it needs molds, which require...
