Automatic umbrella rib riveting device

Abstract

The invention discloses an automatic umbrella rib riveting device. The automatic umbrella rib riveting device comprises a rotary conveying mechanism, wherein an umbrella rib tool for fixing and splicing umbrella ribs is arranged on the rotary conveying mechanism; a long nail riveting device and a short nail riveting device are arranged on the outer side of the rotary conveying mechanism, the umbrella rib tool comprises a plurality of positioning tools, and each positioning tool comprises a first module, a second module, a third module and a fourth module that are adjacent in sequence. After the structure is adopted, when the umbrella rib positioning tool works, umbrella rib sections are placed into the positioning tool firstly, and then the umbrella rib tool is rotated to the long nail riveting device and the short nail riveting device for riveting through the rotary conveying mechanism, separately. Compared with the prior art, the umbrella rib riveting device has the beneficial effects that the automatic umbrella rib riveting device can be used for rivetting long and short rivets of the umbrella ribs automatically, so that the automatic umbrella rib riveting device is time-savingand labor-saving and further improves the rivetting efficiency; and conventional manual operation is replaced by mechanical operation, so that personnel safety accidents can be avoided, defective products are greatly reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of umbrella rib riveting, in particular to an umbrella rib automatic riveting device. Background technique [0002] Umbrella, as a daily necessities for sunshade and rain protection, is used very frequently in daily life. The structure of the umbrella mainly includes an umbrella handle, several groups of umbrella ribs connected with the umbrella handle, and an umbrella surface supported by the umbrella ribs. Generally, umbrella ribs are mostly folded bones, such as figure 2 As shown, the umbrella rib is mainly formed by riveting the round bone 31, the inner connecting bone 32, the inner main bone 33, the middle connecting bone 34, the middle groove main bone 35 and the supporting bone 36 by long rivets and short rivets. [0003] In the existing technology, the umbrella rib riveting technology is still relatively primitive, mainly relying on manual operation, and the umbrella rib segments are put into the riveting ma...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the umbrella rib riveting technology is still relatively primitive, mainly relying on manual operation, and the umbrella rib segments are put into the riveting machine by hand for riveting. Each set of umbrella ribs needs to be riveted with at least seven rivets, and each set of umbrella ribs needs to be separated. Long rivets and short rivets are used for riveting, so the riveting speed is very slow; during operation, workers’ fingers are often at risk of being injured by the riveting machine; however, the production demand for umbrella ribs is very large, so the factory needs a large number of workers to come Riveting umbrella ribs, therefore, this process has high labor costs and the risk of workers being vulnerable to injury; and manual operations are prone to deviations, resulting in poor riveting, long and short nails and other quality problems
