Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing technology, and in particular to a tweeter production line. Background Technology

[0002] A tweeter is an electroacoustic transducer used in audio playback systems. It primarily reproduces the high-frequency components of audio signals to produce clear, bright high-frequency sound. The manufacturing process of tweeters involves multiple applications of adhesive through gluing mechanisms.

[0003] Patent document CN220048803U discloses a loudspeaker bonding and assembly production line. The key technical points are: it includes a frame, a conveying mechanism mounted on the frame, a dispensing mechanism mounted on the frame, a drying mechanism mounted on the frame, and a dust removal mechanism mounted on the frame; the conveying mechanism has multiple chucks for placing loudspeakers, which are moved by the conveying mechanism; the output end of the dispensing mechanism is located above the chucks, and the dispensing mechanism is used to dispense adhesive onto the loudspeakers; the drying mechanism is used to dry the loudspeakers to accelerate the drying speed of the adhesive; and the dust removal mechanism is used to clean and remove dust from the loudspeakers. This invention includes a drying mechanism that can dry the loudspeakers after dispensing, accelerate the adhesive curing speed, and quickly proceed to the next assembly process, thereby improving the assembly efficiency of the loudspeaker production line.

[0004] In the above solution, the production line is equipped with a drying mechanism, but the drying efficiency of the heating wire is low and the drying is uneven, making it impossible to quickly cure the glue in multiple places. This can easily damage the speaker during baking and affect the speaker's production efficiency. Furthermore, the glue for components such as the spider and cone is not dried and needs to be left to stand for a period of time to cure before subsequent assembly. In addition, the production line only performs the gluing step and is not equipped with magnetization and testing mechanisms. Therefore, it is necessary to provide a tweeter production line to address the shortcomings of the existing technology. Utility Model Content

The magnetizing assembly is installed at the rear section of the frame and is used to magnetize the tweeters. The testing assembly is installed at the rear section of the frame, behind the magnetizing assembly, and is used to test the tweeters.

[0035] In this embodiment, the bonding assembly one and bonding assembly two have the same structure, both including a dispensing platform 10, a dispensing bracket 11, a dispensing cylinder 12, a mounting plate 13, a guide shaft 14, and a dispensing tube 15. The bottom of the dispensing bracket is fixedly mounted on the dispensing platform, the dispensing cylinder is mounted on the dispensing bracket, the output shaft of the dispensing cylinder passes through the dispensing bracket and is connected to the top of the mounting plate, the dispensing tube is located below the mounting plate, the top of the dispensing tube is fixedly connected to the mounting plate, and an outlet is provided on the end of the dispensing tube away from the mounting plate. The mounting plate and the dispensing bracket are connected by a guide shaft.

[0036] In this example, the dispensing platform of the first bonding component is equipped with a positioning plate. The T-shaped iron is placed on the positioning plate, and the dispensing cylinder drives the dispensing tube to dispense glue onto the T-shaped iron. This technology is existing technology and will not be described in detail here.
