Description
Technical field
The utility model relates to a kind of handling devices, and in particular to a kind of LED filament column handling device.
Background technique
LED filament has been liked by people more and more as a kind of decorative lighting lamp, different from ordinary incandescent lamp
, what is welded on the glass column in LED filament is LED filament column, which has that illuminance is strong, light-emitting area is big, aobvious
The high advantage of colour index, so as to bring the completely new light visual field.Wherein, in the manufacturing process of LED filament
In, it needs for LED filament column to be welded on glass column, and in the welding process, there is the male and female face (back on LED filament column respectively
Do not shine, sunny side shines), in order to reach better illumination effect, need for sunny side to be welded on outside, back welding in welding
In inside.
In order to reach above-mentioned welding requirements, in the entire welding process of LED filament column, including from blowing station to detection
Station carries station to rotation and arrives welding post again, and the LED filament column at each station requires to show setting appearance
State, any of the above link errors, can all cause the LED filament column posture being located at welding post not up to standard, and then cause
Welding product is unqualified, therefore most important to the gesture stability of LED filament column.
In order to reach the filament column being located at each station in above-mentioned welding all in the requirement of correct posture, in benefit
LED filament column is carried out in handling process with handling device, it is also desirable to retain its posture immobilizes, i.e., feeding, carry with
And during blowing, uncontrollable situations such as LED filament column cannot relatively rotate relative to carrying mechanism, slide.For
Reach the requirement, in the design it is generally considered that (once clamped, posture is maintained for fixing LED filament column using clamping
It is motionless) and the mode of vacuum chuck absorption (LED filament column is once adsorbed, and posture is maintained for fixed) turned
It moves, but the two ways has the following problems in the application:
1, when carrying using method of clamping, since LED filament column is cylindrical, small volume, therefore it is not easy to be pressed from both sides
It holds, and needs to be precisely controlled the size of chucking power in clamping process, when chucking power is excessive, LED filament column (LED can be made
Filament post pole is easy impaired) damage, when chucking power is too small, and it cannot achieve the fixation to LED filament column, therefore which is not
Easily realize.
2, when using using vacuum chuck absorption by the way of when, due to LED filament column be cylinder, vacuum chuck with
The case where it will appear gas leakage during being bonded, which will be greatly reduced the adsorption capacity to LED filament column, remove
Occurs the case where carrying shakiness or deviateing during fortune, to reduce carrying effect.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of LED filament column handling device, the dress
