Description
Technical field
The present invention relates to headlamp production fields, and a kind of LED light sealing machine clamping device is especially arranged.
Background technique
Luminous intensity examination criteria lamp is the magnitude for embodying and transmitting unit of luminous intensity (candela cd), is light spoke
Penetrate the major criterion utensil in measurement.Luminous intensity examination criteria lamp is generally made by incandescent lamp or tungsten halogen lamp, in order to make filament
As the unique illuminator of luminous intensity examination criteria lamp, this kind of lamp is more demanding to seal quality.
The sealing of typical bulb sealing machine at present is generally also needed using sealing after being sintered the high-temp combustion sealing of mouth
Fixture is whole by sealing part equating, to improve seal quality, when extending the service life of light bulb, but sealing, to combine sealing
Uniformly, bracket can be rotated with turntable, be connected between bracket and turntable by support rod, at the end of sealing, in order to avoid supporting pole spacing
Firmly seal clamp influences subsequent job step, and worker is needed to manually adjust bracket locations, this process not only wastes manpower, together
When also reduce whole production efficiency.
To solve the above problems, application No. is the patent documents of CN201310754610.6 to disclose a kind of light bulb sealing
Machine, including rack, combustion gas sintering equipment, bracket system, seal clamp device, axis, worm-gear type gear-box and motor, the combustion
Gas sintering equipment includes position regulation pipe, position adjusting rod, bearing, fuel gas conduit and sintering mouth, and the bracket system includes light bulb
Support ring and rotating disk, there are two the seal clamp devices, is symmetrically mounted on the two of bracket system along station length direction
Side, the seal clamp device include fixture block, connection sheet and sliding block, and the axis is above and below station, upper end and rotating disk
It is connected, lower end is connected on the output belt pulley for the worm-gear type gear-box being fixed on the rack by gear-box belt, the snail
The input belt pulley of wheeled gear-box is connected to motor by motor belt.In use, sintering mouth is connected to by fuel gas conduit
Position adjusting rod, so that the horizontal distance of sintering mouth and light bulb is adjustable, and one end of position adjusting rod is connected with bearing, so that
Sintering mouth can be overturn along position adjusting rod, and the more flexible burning to light bulb in position for being sintered mouth is also more uniform, sealing effect
More preferably；Using bracket system, the light bulb of the various models of size can be carried out to stablize support, and gas tube is located at bracket system
Center, the more conducively adjustment of filament position；Using seal clamp device, pinch off is carried out to light bulb sealing part, so that the envelope of light bulb
Mouth face is more smooth.
The light bulb produced through the above scheme, although sealing formation is smooth, stray light is small when shining, detection effect
Good, improve the production efficiency of enterprise, but still have certain problem: in sintering, lampshade is rotating on one side, exists on one side
Sintering, it will there is hot-engine sludge splashing, and these hot-engine sludges are once splashed on lampshade, lampshade contacts the position of residue
Moment, lampshade was easy to burst because of uneven heating by high temperature.
Summary of the invention
The invention is intended to provide a kind of residue for preventing high temperature to be splashed on lampshade, the LED light sealing that causes lampshade to burst
Machine clamping device.
LED light sealing machine clamping device in this programme, including rack are connected with clamping device in the rack, described
