Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of loudspeaker magnetization, in particular to a headphone loudspeaker magnetization device. Background Art
[0002] Speakers, also known as "horns," are very commonly used electroacoustic transducers. They can be found in all electronic and electrical devices that produce sound, and are one of the most common electroacoustic accessories. During speaker manufacturing, magnetization is required to magnetize magnetic materials or enhance the magnetism of insufficiently magnetic materials. Typically, the magnetic object to be magnetized is placed in the magnetic field generated by a coil passing direct current. A high, instantaneous pulse of current is passed through the coil, generating a brief, extremely strong magnetic field. A capacitor is first charged with a high DC voltage and then discharged through a coil with minimal resistance. The peak discharge pulse current can reach tens of thousands of amperes. This current pulse generates a strong magnetic field within the coil, which permanently magnetizes the hard magnetic material placed within it. The magnetizer is a relatively simple structure: essentially an extremely strong electromagnet equipped with iron blocks of various shapes as additional poles to form a closed magnetic circuit with the object being magnetized. Magnetization is accomplished in an instant by arranging the additional poles and the object being magnetized and applying the excitation current.
[0003] Existing speaker magnetizing devices, such as announcement number CN216287825U, are called a speaker automatic magnetizing machine, which includes a feeding bracket, a discharging bracket and a fixed cylinder. The side of the fixed cylinder is fixedly connected to a magnetizing box, and a magnetizing slot is provided on the top of the magnetizing box.
[0004] However, the above device requires the cooperation of multiple sets of electric clamps to realize the automatic magnetization operation of the speaker. The structure is relatively complicated and the device cost is high. Therefore, we propose an earphone speaker magnetization device to solve the above problems. Utility Model Content

[0028] The stepping motor 12 is mounted on one end of the first conveyor 1 and the second conveyor 3 .
[0029] See also Figure 2 An arc-shaped limit groove 14 is provided inside the push plate 13, and there are three arc-shaped limit grooves 14. When three speakers arrive at the end of the first conveyor 1, the multi-section hydraulic cylinder 6 can control the push plate 13 to extend, and the three arc-shaped limit grooves 14 at the front end of the push plate 13 are used to limit and push the three speakers onto the magnetization table 8. The size of the arc-shaped limit groove 14 is consistent with the specifications of the speaker, which can avoid the speaker from being offset during the pushing process.
[0030] See also Figure 1 and Figure 3 A number of ball mechanisms 15 are provided at the connection between both sides of the magnetizer 2 and the first conveyor 1 and the second conveyor 3. The ball mechanism 15 is composed of a retaining seat at the bottom and internal steel balls, and the steel balls are rollingly connected to the retaining seat. The setting of the ball mechanism 15 makes the speaker move more smoothly and smoothly under the pushing action of the push plate 13.
[0031] See also Figure 1Baffles 9 are installed on the outside of the first conveyor 1, the magnetizer 2 and the second conveyor 3. The baffles 9 can prevent the speakers from deviating during transportation.

[0033] Working principle: When in use, the loading robot arm places the speakers at equal intervals along one end of the first conveyor 1. When the three adjacent speakers move to the end of the first conveyor 1, the multi-section hydraulic cylinder 6 located on the pushing platform 4 is driven to control the push plate 13 to extend, and the three arc-shaped limit grooves 14 at the front end of the push plate 13 are used to limit and push the three speakers to the magnetization platform 8. After the magnetization platform 8 magnetizes the speakers, the output end of the multi-section hydraulic cylinder 6 is further extended, and the push plate 13 is controlled to continue moving forward to push the speakers to the second conveyor 3.
