Light bar glue dispenser capable of preventing glue head from being blocked during LED (Light Emitting Diode) production

Abstract

The invention belongs to the technical field of LED (Light Emitting Diode) lamps, and particularly relates to a light bar glue dispenser capable of preventing a glue head from being blocked during LED(Light Emitting Diode) production. A rotation gear is rotatably connected in a processing seat; a thread stud is rotatably connected in the processing seat; the outer surface of the rotation gear isrotatably connected with a rotation rod; one end of the rotation rod is fixedly connected with an elastic rod; one end of the elastic rod penetrates through the inside of a pressure reduction seat; onone end of the elastic rod, an air pressure bag is arranged in the pressure reduction seat; one end of the pressure reduction seat penetrates through the inside of a conveying pipeline; a telescopicrod is movably connected in the conveying pipeline; the outer surface of the telescopic rod is sheathed with a telescopic spring; and the left side and the right side of the telescopic rod are independently rotatably connected with a regulation rod. During utilization, residual glue in a glue injection head can be sucked out, a blockage phenomenon caused since the residual glue is in the presencein the glue injection head for a long time can be avoided, and the device is guaranteed to be normally used.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to a light strip glue dispenser capable of avoiding clogging of glue heads in the production of LED lamps. Background technique [0002] LED lamps have the advantages of energy saving and environmental protection, and the development of the lighting industry has become a major trend. The bulbs of LED lamps are small in size, light in weight, and encapsulated with epoxy resin, which can withstand high-strength mechanical shock and vibration, not easily broken, and attenuated in brightness The period is long, which utilizes the current to flow forward to the coupling of the semiconductor junction, and then the negatively charged electrons separated by the semiconductor combine with each other to generate photon emission. [0003] In the production of LEDs, the dispensing of the light bars is also very important. At present, during the dispensing process, due to the unsta...

Problems solved by technology

[0003] In the production of LED, the dispensing of its light bar is also very important. At present, when dispensing glue, due to the unstable pressure inside the dispenser, it often leads to uneven dispensing of the light bar, which affects After the dispensing process is carried out, and after a dispensing is completed, there will often be some residual glue in the dispensing head, which will cause blockage inside the dispensing head for a long time, which will affect the normal use of the dispensing machine. Therefore, some In view of this, research and improvement are made on the existing structure and defects, and a light bar dispenser that can avoid the clogging of the glue head in the production of LED lights is provided, in order to achieve the purpose of having more practical value
