Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing equipment technology, and in particular to a magnet feeding device for loudspeaker assembly. Background Technology

[0002] In recent years, with the development of the electronics industry, loudspeakers, as common electronic devices, require the assembly of components such as T-irons, magnets, and frames, resulting in significant manpower investment in material handling at each stage. Among these, magnet handling demands high precision and efficiency. However, loudspeaker magnets are mostly ring-shaped, and existing automated production lines often use vibratory feeders for handling, which can easily lead to magnet damage during storage and retrieval, affecting product quality.

[0003] Traditional feeding methods have several drawbacks: First, manual feeding is labor-intensive and inefficient, and operational errors can easily cause magnet positioning deviations, affecting the magnetic circuit performance of the speaker. Second, existing equipment is difficult to adapt to magnets of different specifications, and changing product models requires adjustments to the mechanical structure, which is time-consuming and labor-intensive. Third, magnets are prone to attracting impurities or sticking together due to their magnetism, which can easily cause jamming during transmission and conveying, leading to feeding interruptions. Fourth, the lifting and pushing actions are not well coordinated, and inconsistent lifting heights or uneven pushing forces often cause magnets to fall or become misaligned, further reducing assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a magnet feeding device for speaker assembly, which solves the problems of traditional manual feeding being time-consuming, labor-intensive, inefficient, and having a high defect rate due to positioning errors. Vibratory feeders are prone to causing damage to the ring magnets due to collisions, and the equipment has poor adaptability, requiring long adjustment and testing. Furthermore, magnets are prone to sticking and jamming, and poor connection between lifting and pushing can cause magnets to fall and become misaligned, affecting efficiency and quality.

[0013] 2. The limiting posts of the loading component provide stable support for the magnet, the frame-shaped lifting plate of the lifting component supports the magnet from the outer ring, and the push plate of the pushing component pushes the magnet smoothly, replacing the vibratory feeder to feed the magnet, reducing collisions, lowering the magnet damage rate, and ensuring product quality.

[0014] 3.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Combination Figures 1-5The illustrated magnet feeding device for speaker assembly includes a base plate 1, two sets of side plates 2 are provided on the upper surface of the base plate 1, an adjusting plate assembly 3 and a loading assembly 4 are provided between the two sets of side plates 2, the loading assembly 4 is located between the adjusting plate assembly 3, a plurality of magnets 5 are provided on the loading assembly 4, a lifting assembly 6 for lifting the magnets 5 is provided between the two sets of side plates 2, a pushing assembly 7 is provided at the upper end of the adjusting plate assembly 3, and a conveyor belt 8 for conveying the magnets 5 is provided on one side of the side plate 2.

[0025] The adjusting plate assembly 3 includes a first adjusting plate 301 and a second adjusting plate 302. Both ends of the lower surface of the first adjusting plate 301 are provided with a first rack 303, and both ends of the lower surface of the second adjusting plate 302 are provided with a second rack 304. Gears 305 are rotatably connected to the inner sides of both sets of side plates 2. When the magnet model needs to be changed, the first adjusting plate 301 is moved, and the gears 305 mesh with the first rack 303 and the second rack 304 respectively, causing the first adjusting plate 301 and the second adjusting plate 302 to move relative to or towards each other. Slider blocks 306 are provided on both sides of the first adjusting plate 301 and the second adjusting plate 302. A sliding groove 307 is provided on the inner side of the side plate 2, allowing the sliders 306 to slide within the groove 307, ensuring a smooth and uninterrupted adjustment process. The sliders are fixed with bolts. This structure solves the problem of requiring significant mechanical adjustments when changing magnet specifications in traditional equipment, greatly shortening the changeover and debugging time and improving production efficiency.

[0026] The material-carrying assembly 4 includes a fixing plate 401, which is inserted between two sets of side plates 2. The fixing plate 401 has two sets of insertion interfaces 402. A support plate 403 is provided on the fixing plate 401. Several sets of limiting posts 404 are provided on the upper surface of the support plate 403, which can separate the magnets 5 one by one to prevent them from sticking together due to magnetic attraction. The upper surface of the limiting posts 404 is flush with the upper surface of the second adjusting plate 302 to ensure that the magnets 5 are subjected to uniform force when pushing the material and to prevent jamming. The lower surface of the support plate 403 is provided with a plug-in block 405, which is adapted to the insertion interface 402. The support plate 403 and the limiting posts 404 are integrated and can be replaced according to the magnet specifications. With the design that the width is smaller than the diameter of the magnet 5, it can provide stable support for the magnets 5 without affecting the supporting action of the lifting assembly 6, thus solving the problem of poor adaptability of traditional material-carrying structures.

[0027] The lifting assembly 6 includes a lead screw 601 rotatably connected to the outer side of the side plate 2 and a guide rod 602 fixedly connected. A motor 603 is provided on the outer side of one side plate 2, and the output end of the motor 603 is connected to the lead screw 601. A lifting plate 604 is provided on the lead screw 601 and the guide rod 602. The lifting plate 604 is connected to the lead screw 601 through a ball nut and to the guide rod 602 through a linear bearing. The part of the lifting plate 604 located between the two sets of side plates 2 is frame-shaped and located on the outer ring of the bearing plate 403, in contact with the magnet 5, so as to support the magnet 5. This structural design makes the magnet 5 subjected to uniform force during the lifting process, and will not deform or be damaged due to excessive local force. Compared with the vibratory feeder feeding method, the magnet damage rate is greatly reduced.

[0028] The pushing component 7 includes a cylinder 701, and a pusher plate 702 is provided at the output end of the cylinder 701. When the lifting component 6 lifts the magnet 5 to a specified height, the cylinder 701 drives the pusher plate 702 to move forward at a constant speed, accurately pushing the magnet 5 onto the conveyor belt 8. The pushing force of the pusher plate 702 can be adjusted by air pressure to avoid damage to the magnet 5 due to excessive force.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.
