Problems solved by technology

Most of the existing detection methods are manually put the sound film into the mold tooling, and use the human eye to observe the detection method. The manual detection method has poor accuracy and low efficiency, and the manual detection method is subjective in judgment and cannot guarantee detection. Consistency of standards leads to low product yield and many complaints from customers

Embodiment Construction

[0018] Below, the present invention will be further described in combination with specific embodiments.

[0019] refer to figure 1 , figure 2 , image 3 and Figure 4 , the sound film detection device of this embodiment includes a frame (not shown), an operating platform 1 , a 3D laser camera box 2 , a 2D camera assembly 3 , a fixture tray 4 and a tray frame 5 .

[0020] The operating platform 1 is arranged on the frame and is a testing platform for sound film products. The jig tray 4 is used to place the sound film product to be tested, and the jig tray 4 is placed on the tray frame 5 provided on the operating platform 1 . The jig tray 4 in this embodiment is provided with a plurality of sound film placement grooves for placing the sound film, so that multiple sound films on the jig tray 4 can be continuously detected, thereby improving efficiency. The tray frame 5 is movably arranged on the operating platform 1. In this embodiment, the operating platform 1 is provided ...

Abstract

The invention discloses a voice diaphragm detection device, comprising an operation platform; tray racks set on the operation platform, wherein jig trays for placing voice diaphragm are set on the tray racks; a 3D laser photographing box set on the operation platform, wherein the 3D laser photographing box is located above the jig trays, and a 3D camera is set in the 3D laser photographing box; and a 2D photographing assembly set on the operation platform, wherein the 2D photographing assembly is located below the jig trays, and the 2D photographing assembly comprises a dome light source and acamera located below the dome light source. According to the device, concentricity and depth of the voice diaphragm can be detected, efficiency is high and precision is high.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, and in particular relates to a detection device for detecting the concentricity and depth of a sound membrane. Background technique [0002] The sound film is an integral part of the loudspeaker vibration system and an important part to realize electro-acoustic conversion. Before the sound film is assembled into the finished speaker, the concentricity and depth of the sound film need to be tested to ensure the quality of the product. The bottom of the sound membrane has a smooth concave surface, and the distance (depth) between the bottom of the sound membrane and the top plane and the concentricity between the bottom plane and the top plane need to be monitored during testing. Most of the existing detection methods are to manually put the sound film into the mold tooling, and use the human eye to observe the detection method. The manual detection method has poor accuracy and low eff...
