Tungsten Halogen Lamp High Voltage Shock Detection Device

Abstract

The invention discloses a halogen tungsten light high pressure shocking detecting device which comprises a high pressure assembly and an electrical appliance controlling device. The high pressure assembly comprises an insulation substrate and a left electrode assembly and a right electrode assembly. The left electrode assembly and the right electrode assembly are arranged symmetrically on the insulation substrate. Each electrode assembly respectively comprises a supporting seat. The supporting seat is composed of a base, a vertical arm and a hanging arm fixed on the vertical arm. An insulation cushion and a copper electrode block are installed on the base from down to up in sequence. An air cylinder is installed on the hanging arm and a cylinder-shaped copper pressing piece is installed at the output end of the air cylinder in an insulating mode. The cylinder-shaped copper pressing piece and the copper electrode block are aligned up and down and a gap is formed. The electrical appliance controlling device comprises a programmable logic controller (PLC) controlling return circuit and a high pressure shocking return circuit. The copper electrode block is connected with the high pressure shocking return circuit. The halogen tungsten light high pressure shocking detecting device is simple in structure, convenient to operate and capable of controlling shocking time and voltage precisely. Detecting results can be judged intuitively.

Description

technical field [0001] The invention relates to the field of manufacturing tungsten-halogen lamps, in particular to a high-voltage impact detection device for tungsten-halogen lamps dedicated to laser printers. Background technique [0002] When manufacturing tungsten-halogen lamp tubes for laser printers, the filament, molybdenum foil, and molybdenum rod in the lamp tube are assembled by spot welding, so four process solder joints are formed on the molybdenum foil. When the lamp tube is sealed, the welding spot is clamped and sealed together with the quartz glass shell of the lamp tube. The quality inspection of the solder joints is a crucial link for technical performances such as product reliability, safety and service life. [0003] The existing method for inspecting the solder joints on the molybdenum foil is as follows: place the lamp tube on a lighting workbench, start and close the switch manually, perform high-voltage impact on the lamp tube, and then check the qua...

AI Technical Summary

Problems solved by technology

Because the power is turned on and off manually, the high-voltage impact time is affected by subjective and objective factors and cannot be accurately controlled, so it is impossible to accurately judge the quality defects of the lamp solder joints
