Automatic pipebender
Technical field
The present invention relates to a kind of lamps and lanterns manufacturing technology equipment, and in particular to a kind of automatic pipebender of the U-shaped fluorescent tube of fluorescent lamp.
Background technique
Fluorescent tube and ballast etc. are combined into the lighting apparatus of an entirety ----fluorescent lamp is as LED light
A kind of important energy-saving lamp.Wherein, U-tube, helix tube and three kinds of straight tube can be divided by the shape of fluorescent tube.Further
Ground, U-tube have the plurality of specifications such as T2U, T3U, T4U, T6U, T8U, T10U and T12U again, are usually used in family, hotel, school, doctor
The ground such as institute have service life long [8,000 hours or more], light efficiency high [being 5-6 times of common bulb], small in size and colour developing well etc. excellent
Point." T " in " T2U " indicates caliber, and " 2 " indicate the specific value of caliber, and unit is inch.Theoretically, thinner fluorescent tube effect
Rate is higher, that is to say, that identical wattage shines more.In actual use, thin fluorescent tube is easy hidden, and use occasion is also flexible.
But thinner fluorescent tube starting is more difficult, also gives a discount a little in terms of the service life, therefore according to finding after Market Research, T12U
Product still has larger demand in market.In the production process of U-shaped fluorescent tube, there is dusting, roasting head crocus, roasted tube, sealing, curved
The multiple working procedures such as pipe, exhaust, seasoned, and bend pipe is one of very important process, directly influences the quality of fluorescent tube.
Application number: 200920044206.9, the Chinese utility model of entitled " big-U type energy-saving lamp tube automatic pipe bender " is special
Benefit discloses a patented technology, it " including rack, station index dial, transmission mechanism, large U type mold, feeding warehouse, heating baking
Case, automatic conveying device, alternately coordinated type clamp transfer device, flame device and down tube mechanism;The station index dial installation
On the rack, station index dial is driven by transmission mechanism and is rotated, and the large U type mold is fixed on station index dial, in rack
Feeding warehouse is installed, feeding warehouse is communicated by automatic conveying device with the heated oven, and heated oven setting is in station point
Above scale, heated oven position is corresponding with large U type die location, and the spray of mold preheating effect has been provided in the rack
Fiery device and down tube mechanism, the two sides of heated oven are provided with alternately coordinated type clamp transfer device;The alternately coordinated type folder
Pipe transfer device includes guide rail, cylinder, first group of manipulator, second group of manipulator, third manipulator, and described first group mechanical
Hand and second group of manipulator include the manipulator of identical quantity, and the distance between manipulator is also identical, first group of manipulator installation
On guide rail, second group of manipulator is oppositely arranged with first group of manipulator, and position is lower than first group of manipulator, can automatic lifting
Third manipulator the lower sections of above-mentioned two groups of manipulators is set, All Robots are driven by cylinder." ask existing for the patent
Topic is: the bend pipe processing that cannot be applicable in T12U production.Therefore, present T12U product still uses manual mode to carry out curved
Pipe process operations, and use manual mode to carry out bend pipe process operations and then have the following problems:
1. production efficiency is low, and yield only 60/when;
2. couple employee requires height, higher technical ability and proficiency are needed;
3. staff labor intensity is big, it is affected by human factors, qualification rate only 85% or so, and homogeneity of product is poor;
4. operator is more, occupied area is wide, high production cost;
5. frit after bend part softening is easy tenesmus since T12U type fluorescent tube caliber is big, lead to bend part not
Good sizing, to influence qualification rate;
6. bend part glass-tube outboard sidewalls thickness differs greatly, and influences T12U type fluorescent tube since product opens shelves and caliber is larger
Quality.
