[0015] The testing method of the automatic horn quality testing equipment includes the following steps:

[0016] Step 1: Place the speaker on the placement plate. Start the hydraulic telescopic rod to move the moving block. When the moving block moves, it moves the base rod. When the base rod moves, it moves the clamping plate, thereby clamping the speaker.

[0017] Step Two: The motor starts and drives the first gear to rotate. When the first gear rotates, it drives the first rack to move. When the first rack moves, it drives the bottom column to move, which in turn drives the placement plate to move. When the placement plate moves, it drives the first moving ring to slide on the moving rod. When the first moving ring moves, it drives the top rod to move. When the top rod moves, it drives the main extrusion block to move. The main extrusion block extrudes the auxiliary extrusion block. At this time, the spring shortens and drives the moving column to slide, which in turn drives the connecting plate to rise and move the connecting plate out of the protective box. At this time, the motor continues to rotate, and the placement plate continues to move, driving the horn to move below the energized contact. The energized contact connects with the contact point on the horn, and the energized contact energizes the horn, and the horn emits a sound.

[0018] Step 3: When the auxiliary extrusion block rises, it drives the third rack to move. When the third rack moves, it drives the second gear to rotate, which in turn drives the second rack to move. When the second rack moves, it drives the first support column and the sound quality detector to move, causing the sound quality detector to slide out of the storage box to detect the sound emitted by the speaker, thereby detecting the quality of the speaker.

[0019] Beneficial technical effects of the present invention:

[0020] 1. According to the automatic horn quality detection equipment and method of the present invention, by setting up a protective box, the motor starts and drives the first gear to rotate. When the first gear rotates, it drives the first rack to move. When the first rack moves, it drives the bottom column to move, which in turn drives the placement plate to move. When the placement plate moves, it drives the first moving ring to slide on the moving rod. When the first moving ring moves, it drives the top rod to move. When the top rod moves, it drives the main extrusion block to move. The main extrusion block moves away from the auxiliary extrusion block. At this time, the spring extends and drives the moving column to slide, which in turn drives the connecting plate to descend and slide the connecting plate into the protective box. At this time, the unused connecting plate and the power contact can be protected, and the connecting plate and the power contact are not easily damaged by collision.

[0021] 2. By setting up a storage box, when the auxiliary extrusion block descends, it drives the third rack to move. When the third rack moves, it drives the second gear to rotate, which in turn drives the second rack to move. When the second rack moves, it drives the first support column and the sound quality detector to move, sliding the sound quality detector into the storage box. This protects the unused sound quality detector and prevents it from being damaged by impact. Attached Figure Description

[0039] In this embodiment, as shown in Figures 1-12, the working process of the automatic speaker quality detection equipment and method provided in this embodiment is as follows:

[0040] Step 1: Place the speaker on the placement plate 2. Start the hydraulic telescopic rod 38 to move the moving block 31. When the moving block 31 moves, it moves the bottom rod 32. When the bottom rod 32 moves, it moves the clamping plate 3, thereby clamping the speaker.

[0041] Step 2: The motor 4 starts and drives the first gear 44 to rotate. When the first gear 44 rotates, it drives the first rack 43 to move. When the first rack 43 moves, it drives the bottom column 45 to move, which in turn drives the placement plate 2 to move. When the placement plate 2 moves, it drives the first moving ring 22 to slide on the moving rod 25. When the first moving ring 22 moves, it drives the top rod 23 to move.

At this time, the motor 4 continues to rotate, and the placement plate 2 continues to move, which moves the horn to the bottom of the energized contact 891. The energized contact 891 connects with the contact point on the horn, and the energized contact 891 energizes the horn, and the horn emits a sound.

[0042] Step 3: When the auxiliary extrusion block 85 rises, it drives the third rack 83 to move. When the third rack 83 moves, it drives the second gear 52 to rotate, which in turn drives the second rack 5 to move. When the second rack 5 moves, it drives the first support column 53 and the sound quality detector 54 to move, so that the sound quality detector 54 slides out of the storage box 7 to detect the sound emitted by the speaker, and thus detect the quality of the speaker.

By setting the second support rod 84, the third rack 83 can be easily supported. By setting the protective box 6, the motor 4 starts and drives the first gear 44 to rotate. When the first gear 44 rotates, it drives the first rack 43 to move. When the first rack 43 moves, it drives the bottom column 45 to move, which in turn drives the placement plate 2 to move. When the placement plate 2 moves, it drives the first moving ring 22 to slide on the moving rod 25. When the first moving ring 22 moves, it drives the top rod 23 to move. When the top rod 23 moves, it drives the main extrusion block 24. As the main extrusion block 24 moves away from the auxiliary extrusion block 85, the spring 892 extends, causing the moving column 8 to slide, which in turn causes the connecting plate 89 to descend, sliding the connecting plate 89 into the protective box 6. This protects the unused connecting plate 89 and the energized contact 891 from collision damage. The hydraulic telescopic rod 38 and clamping plate 3 facilitate clamping and limiting the horn. The support ring 36, side block 37, and outer frame 39 work together to support the hydraulic telescopic rod 38. The guide ring 33 is slidably connected to the guide rod 35 to guide and limit the clamping plate 3. The bottom rod 32 facilitates... The clamping plate 3 is supported by the second support column 71, which facilitates the support of the storage box 7. The slide bar 55 is slidably connected to the slide groove, which facilitates the guidance and limiting of the sound quality detector 54. The first rotating rod 51 is rotatably connected to the top plate 82 through the bearing. When the auxiliary pressing block 85 descends, the storage box 7 drives the third rack 83 to move. When the third rack 83 moves, it drives the second gear 52 to rotate, which in turn drives the second rack 5 to move. When the second rack 5 moves, it drives the first support column 53 and the sound quality detector 54 to move, sliding the sound quality detector 54 into the storage box 7. This protects the unused sound quality detector 54 from collision damage.
