An automatic error-preventing leak riveting method and riveting equipment

Abstract

The invention discloses an automatic error-proof and missing riveting method, which comprises the following steps: the riveting part feeding part sends the riveting part to be riveted to a set riveting position; the workpiece clamping and moving part sends the workpiece to be riveted to a set position The position of the workpiece; the riveting part rivetes the riveting part at the set riveting position to the workpiece at the setting position; it is characterized in that: the riveting part includes an upper riveting module device and a lower riveting module device , wherein, the upper riveting module device is provided with an air pressure module, and the air pressure module includes an air suction working unit and an air pressure change monitoring unit; the upper riveting module device and the lower riveting module device cooperate with each other to rivet the riveting parts to the workpiece , the air suction working unit produces air suction on the rivet at the set position of the rivet, and the air pressure change monitoring unit monitors the change of the air pressure value, and judges whether it is adsorbed to the rivet to be riveted or whether the adsorption is judged by the change of air pressure. To what kind of rivet. The invention also discloses an automatic error-preventing leakage riveting equipment.

Description

technical field [0001] The invention relates to automatic riveting and pressing technology, in particular to an automatic riveting and pressing method for preventing errors and omissions and riveting and pressing equipment. Background technique [0002] The current automatic riveting and pressing equipment roughly includes the following parts: workpiece clamping and moving platform part, (stud or pin) feeding part, riveting and pressing part and detection part. Among them, the (stud or pin) feeding part is generally fed by vibrating disk guide rails or the manipulator is clamping and feeding, the riveting part is matched with the upper and lower modules, and the detection part is conventional machine vision detection. The current automatic riveting and pressing equipment, the riveting and pressing process is that a single (stud or pin) is loaded in place, and the (stud or pin) is riveted to the workpiece on the platform through the riveting and pressing part. After the rivet...

Problems solved by technology

However, the current riveting equipment relies on machine vision to detect the overall riveting condition of the workpiece after the riveting process.

Moreover, most of the current riveting equipment is for automatic riveting of a single type (screw or pin). The equipment is carried out, which greatly reduces the riveting efficiency

What's more, when the same workpiece involves multiple types (studs or pins), since different types (studs or pins) are often only slightly different in diameter, length, etc., once there is a wrong riveting (For example, A (stud or pin) should be riveted but B (stud or pin) is wrongly riveted, there is no missing riveting, just wrong riveting), visual inspection cannot accurately detect and judge

Therefore, there are still many unreasonable places in the traditional automatic riveting equipment, which need to be improved and perfected.
