Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention will be further described:

[0012] like figure 1 and figure 2 As shown, the halogen bulb molybdenum rod molybdenum sheet solder joint detection mechanism has a worktable 1, and the workbench 1 is formed by connecting a square table 2 and an arc table 3. Specifically, the top surface 4 of the square table 2 and the arc table 3 The ends 5 are connected tangentially, which can ensure that the wick 6 is in the clamping mechanism of the turntable ( figure 2 (not shown in ) when clamping and rotating, it first encounters the arc-shaped platform 3, and gradually and smoothly rises into the top surface 4 of the square platform along the arc surface. On square table 2 sides, be fixed with first conductive plate 7 and second conductive plate 8, both can select copper sheet to make for use, leave gap 12 between the first conductive plate 7 and the second conductive plate 8, this gap can not exceed The leng...

Abstract

The invention discloses a welding spot testing mechanism for a molybdenum rod and a molybdenum plate of a halogen bulb. The testing mechanism comprises a worktable which is obtained through connecting a square table and an arc-shaped table. The top surface of the square table is tangentially connected with the end of the arc-shaped table. A first conductive board and a second conductive board are fixed on the side surface of the square table. A clearance is reserved between the first conductive board and the second conductive board. The upper edges of the first conductive board and the second conductive board are higher than that of the square table. The first conductive board and the second conductive board are electrically connected and are connected with a lead. The welding spot testing mechanism is used in cooperation with a turntable which clamps a lamp wick and a PLC control system. The welding spot testing mechanism can conveniently and quickly select the lamp wicks with welding failure in the molybdenum rod and the molybdenum plate, thereby effectively ensuring qualified rate of the lamp wicks.

Description

technical field [0001] The invention relates to a device, in particular to a detection mechanism for whether the welding spot between the molybdenum rod and the molybdenum sheet in a halogen bulb is open. Background technique [0002] Halogen lamps are lighting fixtures used in many cars now. Halogen lamp bulbs are made of a wick installed in a transparent glass shell, filled with halogen gas, and then installed on the lamp holder. The wick is made of molybdenum rods welded at both ends of two molybdenum sheets, and then the filament is suspended by two molybdenum rods on one side, and a glass support is connected to the molybdenum rods on the side. In the production process, testing the welding quality of molybdenum rods and molybdenum sheets is an important process, and unqualified wicks with cracked solder joints must be selected in time to ensure the pass rate of the final halogen lamp. The current detection method is mainly based on manual selection. Workers gently sha...
