Led lamp sealing machine clamping device

Abstract

The invention relates to the field of illumination lamp production, and discloses a clamping device of an LED lamp sealing machine. The clamping device comprises a machine frame. Clamping mechanisms are connected to the machine frame. Each clamping mechanism comprises a cylinder. The cylinders are fixedly connected to the machine frame. Mechanical arms are connected to the cylinders. Each mechanical arm comprises a clamping arm frame, a first clamping finger, a second clamping finger and a slide block shaped like a Chinese character 'ba'. Through holes are formed in the clamping arm frames. Piston rods penetrate the through holes and are arranged in a sliding manner. One end of each piston rod is connected with the corresponding cylinder. The slide blocks shaped like the Chinese character 'ba' are connected to the first clamping fingers and the second clamping fingers in a sliding manner. A water belt is connected between each first clamping finger and the corresponding second clamping finger. One end of each water belt is connected to the inner side of the corresponding first clamping finger, and the other end of each water belt is connected to the inner side of the corresponding second clamping finger. Water inlet pipes are arranged at the top ends of the water belts and are connected with constant-pressure water supply devices. Water spray pipes are connected with the two sides of each water belt and penetrate the clamping fingers to be connected with first valves. Compared with the prior art, the situation that high-temperature residues splash to lampshades and the lampshades crack can be prevented.

Description

technical field [0001] The invention relates to the field of lighting lamp production, in particular to a clamping device for an LED lamp sealing machine. Background technique [0002] The luminous intensity detection standard lamp is used to reflect and transmit the value of the luminous intensity unit (candela cd), and is an important standard instrument in the measurement of light radiation. Standard lamps for luminous intensity testing are generally made of incandescent lamps or tungsten halogen lamps. In order to make the filament the only illuminant of the standard lamp for luminous intensity testing, this kind of lamp has higher requirements for sealing quality. [0003] At present, after the sealing of the typical bulb sealing machine is sealed by high-temperature combustion of the sintering nozzle, it is generally necessary to use a sealing fixture to smooth the sealing place to improve the sealing quality and prolong the service life of the bulb. The bracket will ...

AI Technical Summary

Problems solved by technology

[0005] Although the bulbs produced by the above scheme have a flat and smooth seal, little influence of stray light when emitting light, good detection effect and improved production efficiency of the enterprise, there are still certain problems: during sintering, the lampshade is rotating while sintering, There will be high-temperature residues splashing, and once these high-temperature residues splash on the lampshade, the position where the lampshade touches the residue will be heated instantly, and the lampshade will easily burst due to uneven heating
