Problems solved by technology

[0005] Due to the many steps in the production process of tungsten filament lamps, it needs to be transferred many times in the production process. Various losses may occur during the transfer and processing of the lamp tubes, and the welding effect may be poor due to various reasons. Therefore, the ex-factory quality of the existing tungsten lamp tubes is difficult to guarantee; in addition, the printer still needs long-distance transportation after packing, and the problem of desoldering may still occur during the long-distance transportation

Embodiment 1

[0025] In a typical implementation of the present invention, this embodiment discloses an overload inspection device for a heating lamp tube of a printer, which includes a first energizing part 3 , a second energizing part 4 , a power supply and a switch 8 , the first energizing part 3 and the first energizing part 3 and the second energizing part 4 The two energizing parts 4 are arranged at intervals, and the distance between the first energizing part 3 and the second energizing part 4 is smaller than the total length of the lamp to be tested, and the distance between the first energizing part 3 and the second energizing part 4 is larger than that of the lamp to be tested The length of the glass tube of the lamp; the tops of the first energizing part 3 and the second energizing part 4 both have a plane for placing the terminals of the lamp to be tested; There is switch 8.

[0026] It should be noted that the heating lamp tube of the printer in this embodiment includes a tungs...

Embodiment 2

[0041] In a typical implementation of the present invention, this embodiment discloses a method for testing the overload of a heating lamp of a printer. The test voltage greater than the rated voltage is applied to the terminals at both ends to perform high-voltage impact testing, and then visual inspection and resistance testing are performed.

[0042]Specifically, during the high-voltage impact, the two ends of the lamp to be tested are placed on the first energizing part 3 and the second energizing part 4 respectively, and the power supply applies a test voltage higher than the rated voltage. When the finished lamp appears after the high-voltage impact After abnormality, it is classified as defective product;

[0043] Carry out a visual inspection to check whether the tungsten wire, molybdenum sheet and molybdenum rod are de-soldered after high pressure impact;

[0044] Conduct resistance detection, use a resistance detector to connect both ends of the finished lamp tube fo...

Abstract

The invention discloses a printer heating lamp tube overload detection device and method, belongs to the technical field of tungsten filament lamps, and aims to test a printer heating lamp tube before leaving a factory by using an overload pressurization method and cooperate with a detection process to improve the outgoing quality of the lamp tube. The printer heating lamp tube overload inspection device comprises first electrifying parts, second electrifying parts, a power supply and a switch, wherein the first electrifying parts and the second electrifying parts are arranged at intervals, the distance between the first electrifying parts and the second electrifying parts is smaller than the total length of a lamp tube to be tested, and the distance between the first electrifying parts and the second electrifying parts is larger than the length of a glass tube of the lamp tube to be tested; the top ends of the first electrifying part and the second electrifying part are respectively provided with a plane for placing a lamp tube terminal to be tested; the first electrifying parts and the second electrifying parts are connected with the power supply which is provided with the switch.

Description

technical field [0001] The invention belongs to the technical field of tungsten filament lamps, and in particular relates to an overload inspection device and method for a heating lamp tube of a printer. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] The toner cartridge of the printer is an important part of the printer. The toner cartridge must be heated during fixing, otherwise the image formed by the toner cannot be fixed on the paper. The laser printer must rely on high temperature and pressure to melt the image on the paper. Due to the compact internal structure of the toner cartridge, the heating components in it also need to have the characteristics of high integration and stable performance. At present, the commonly used heating components of printer toner cartridges are tungsten filament lamps. [0004] The inventor found that the existing tungsten...
