Technical Field

The invention relates to the technical field of automatic assembly machinery, and particularly provides an automatic assembly machinery for cylindrical LED projection lamps.

Background

The cylindrical LED floodlight can also be simply called an LED down lamp, and the appearance and the structure of the LED down lamp are various, but the common LED down lamp structure basically comprises a down lamp body, a down lamp surface ring, a down lamp light source, a down lamp diffusion plate, a torsion spring (clamp spring) and other structures.

The lamp shade structure of the LED down lamp in one structural form consists of a down lamp body and a down lamp surface ring, wherein two torsion spring assembling positions for the buckling assembly of torsion springs are processed on the down lamp body, and the torsion bar part of the torsion spring structure assembled with the lamp shade can be in a polished rod form or can be wrapped with a rubber sleeve; when assembling this type of structure LED down lamp, two torsion springs need to be snap-fitted to the lamp housing. In the traditional assembly and assembly process, the assembly of the assembly line is mostly carried out in a manual mode, the torsion spring is required to be pinched manually, the torsion spring is buckled at the assembly position of the lampshade after being elastically deformed, and the following problems are obviously caused by manual assembly and assembly: 1. when the manual assembly is adopted, the assembly positions of the two torsion springs of the lampshade are required to be assembled in a buckling mode one by one, synchronous assembly cannot be achieved, the assembly efficiency is low, and the assembly efficiency is greatly affected by human factors.

2. When the manual assembly is adopted, the torsion spring is required to be pinched manually, whether the torsion spring is pinched by bare hands or is pinched by aid of a tool, the labor is wasted, and muscle strain of the hand is easily caused by long-time operation.

In addition, the invention patent with the application number of CN201910690472.7 discloses an automatic assembly mechanism of a down lamp torsion spring, which comprises a seat disc, a discharging plate and a supporting rod, wherein the right lower air cylinder and the left lower air cylinder do X-axis up-down movement, and drive a turning plate to move simultaneously, and the turning plate drives a lower pressing shifting piece to extrude the elastic end of the torsion spring and deform, so that the deformed torsion spring enters a cross rod part where the down lamp needs to be installed. The invention can replace manual work to complete the automatic assembly of the torsion spring, but still has the following defects: firstly, the mechanism can only execute the assembly action of the torsion spring, can not realize automatic conveying and batch assembly operation of the torsion spring, and has low automation degree; secondly, the synchronous installation of two torsion springs in the down lamp structure cannot be completed by the mechanism, and only the assembly installation of a single torsion spring can be realized.
