Description

Technical Field

[0001] The invention relates to the field of halogen tungsten lamp tube manufacturing, and in particular to a multi-station horizontal porcelain head loading device for a double-tube metal sheet halogen tungsten lamp for a multi-function copier / laser printer and a use method thereof. Background Art

[0002] According to the output speed, multi-function copiers / laser printers can be divided into three categories: low-speed machines, medium-speed machines and high-speed machines. In the fixing assembly of low-speed machines, a single fixing halogen tungsten lamp is usually used as a heat source, while the fixing assemblies of high- and medium-speed machines, including color machines, mostly use double fixing halogen tungsten lamps as heat sources. The double fixing halogen tungsten lamp tubes are composed of main and auxiliary fixing halogen tungsten lamp tubes, and adopt a complementary design to increase the output speed and improve the energy saving effect of the equipment. At present, the conventional double-tube halogen tungsten lamp is generally fixed by inserting the left and right sides of the lamp tube into the double-slot double-hole porcelain head, and fixing the lamp tube as a whole by injecting solder mud into the inside of the porcelain head to meet the assembly requirements of the lamp tube and the printing equipment.

[0003] The new double-tube fixing halogen tungsten heating lamp (double-tube metal sheet halogen tungsten lamp) adopts the method of welding metal terminals (metal sheets) on both sides to meet the assembly requirements of the lamp tube and the printing equipment. However, due to the conductivity of the metal terminals, the two lamp tubes cannot be assembled into a unified whole by the metal terminals alone. Therefore, it is necessary to install a double-hole porcelain head assembly on the same side of the two lamp tubes to ensure that the two lamp tubes are a unified whole. If this porcelain head installation method is manually assembled, its installation size and consistency cannot be guaranteed, and the production efficiency is too low to meet the needs of mass production.

The multi-station horizontal porcelain head loading device for double-tube metal sheet tungsten halogen lamp according to claim 5, characterized in that: The side of the machine platform (1) is provided with a welding paste gun rack (12) for placing a welding paste gun (13), a lifting cylinder control switch (11) and a traction cylinder control switch (18); the traction cylinder (4) and the lifting cylinder (7) are both connected to pipelines connected to compressed air, and the compressed air drives the cylinders to operate. The lifting cylinder control switch (11) controls the vertical movement of the strip sheet in the parallelism assurance mechanism, and the traction cylinder control switch (18) controls the left and right movement of the main working plate (10) on the top surface of the machine platform (1).

7. The multi-station horizontal porcelain head loading device for double-tube metal sheet tungsten halogen lamp according to claim 1, characterized in that: The common end mold fixing strip (5) is fixedly connected to the brackets (6) at both ends thereof, and a strip groove is provided below the common end mold fixing strip (5). Screws pass through the strip groove to connect the common end mold fixing strip (5) to the main operation plate (10), and the connection position can be adjusted.

8. The method for using the multi-station horizontal porcelain head loading device for double-tube metal sheet tungsten halogen lamp according to any one of claims 1 to 7, characterized in that: First, using a standard lamp tube with the same specifications as the one to be processed, a corresponding common end mold (19) and a non-common end mold (20) are selected and installed on the common end mold fixing strip (5) and the non-common end mold fixing strip (16) respectively, and the distance between the two is adjusted to adapt to the length of the lamp tube, and the porcelain head limiting plate (25) is installed and adjusted to contact the porcelain head (22) of the standard lamp tube; the two ends of the lamp tube of the double-tube metal sheet tungsten halogen lamp to be processed are placed in the corresponding mold, the position of the porcelain head (22) is adjusted so that it is against the porcelain head limiting plate (25), and the strip sheet of the parallelism ensuring mechanism is started to move downward until it presses the metal terminals and the porcelain head (22) at both ends of the lamp tube; and after injecting solder paste (29) into the porcelain head (22), a hot air system is started to dry and fix it.
