Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting lamp production, in particular to a lighting lamp assembling and conveying device. BACKGROUND

[0002] In the field of engineering lighting, LED lamps have become the mainstream lighting products due to their low energy consumption, long service life, high brightness, environmental protection and other advantages. LED lamps are usually composed of core components such as bulb shell, light source board, lamp holder and bulb. The assembling process has clear stages: first, the light source board is precisely pressed and fixed on the bulb shell by manual or automatic equipment to complete the preliminary assembly; then, the bulb shell loaded with the light source board is conveyed to complete the lamp holder assembly, power-on test, excess wire cutting, rivet installation and lamp holder locking procedures; after the lamp holder related procedures are completed, the bulb shell needs to be sealed by dispensing, and then the bulb is installed to realize overall packaging, and finally the product information is marked by laser marking, thereby realizing the complete assembly of LED lamps.

[0003] At present, the assembling and conveying of LED lamps mostly adopts a step-by-step rotating conveying system, which mainly includes two step-rotating rotating discs. Each rotating disc is installed with a mold matched with the bulb shell. In the assembling process, the first rotating disc carries the bulb shell through the mold and drives it to step-rotate, thereby sequentially completing the assembly of the bulb shell and the lamp holder. When the lamp holder assembly is completed, the bulb shell is grabbed and flipped 180 degrees by a flipping robot, and then transferred to the corresponding mold of the second rotating disc. The second rotating disc continues to drive the bulb shell to step-rotate, thereby completing the subsequent procedures such as dispensing, bulb assembly and laser marking, so as to realize the assembling and conveying of the lamp.

[0004] The existing problems in the assembling and conveying of lamps are as follows: after the flipping robot flips the bulb shell by 180 degrees, it is difficult to ensure that the bulb shell accurately falls into the mold of the second rotating disc, and positioning deviation is easy to occur, which causes the bulb shell to fail to maintain a vertical state in the bulb assembly process, affecting the precision of dispensing, bulb assembly and other processes, and further affecting the quality of the assembled lamp.
