Description

Technical Field

[0001] The utility model relates to the technical field of industrial production devices, in particular to a device mainly used for detecting glue on the neck of a voice coil of a speaker product. Background Art

[0002] During the speaker production process, glue is needed to stick the voice coil. Since speakers are high-precision products, excessive or insufficient glue will affect the performance of the speaker, so the glue needs to be detected and identified to ensure that the glue meets the requirements. At present, CCD cameras are generally used for shooting and identification. The camera is installed above the speaker production line and aimed at the voice coil to shoot, so as to identify the parts where the glue does not meet the requirements. However, since the camera is just above the voice coil and will be blocked by the voice coil itself, there are blind spots that cannot be photographed during shooting, and secondly, this angle similar to the overhead projection will cause some parts to be not clearly identified, resulting in poor recognition effect and missing many products with quality problems. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a voice coil neck glue identification device which has a simple structure, a more reasonable design, a good shooting effect and no blind spot in identification.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solution: a voice coil neck glue identification device, including a supporting mechanism and a camera (especially a smart camera), a driving mechanism is installed on the supporting mechanism, the driving mechanism is connected to a swinging mechanism, and the camera is installed on the swinging mechanism to form a structure that can rotate around the voice coil for shooting as the swinging mechanism rotates.

[0005] Furthermore, the swing mechanism includes a swing arm, which is connected to the driving mechanism to form a structure that can rotate and swing; a fixing plate is installed on the swing arm, and the camera is installed laterally on the fixing plate and aimed at the glue-coated part of the speaker product for assembling the voice coil.

[0006] Furthermore, a mounting hole is provided on the fixing plate, and the camera is mounted on the mounting hole via an axle pin to form a structure that can be rotated and adjusted in angle.

[0007] Furthermore, an arc-shaped adjustment hole is provided on the fixing plate, with the mounting hole as the center. The camera is connected with a positioning shaft, which is inserted into the adjustment hole. After the camera is adjusted to the right angle, the positioning shaft is locked to achieve the positioning of the camera.

[0008] Furthermore, a sensor for detecting whether the speaker product has moved into position is installed on the supporting mechanism.

[0009] Furthermore, the supporting mechanism adopts a gantry, which is arranged across the speaker production line.

[0010] Furthermore, the supporting mechanism includes pillars and cross braces, the pillars are respectively arranged on both sides of the speaker production line, and the cross brace is suspended above the speaker production line; the pillars are made of aluminum profiles, and the cross brace is installed on the left and right pillars through clamps to have a structure that can adjust the height up and down.

[0011] Furthermore, the driving mechanism includes a motor, the motor is connected to a driving wheel, the driving wheel is connected to a driven wheel via a synchronous belt, and the swing arm is connected to the driven wheel.

[0012] Furthermore, the sensor is installed on the inner side of the pillar through a fixing seat to form a structure whose height position can be adjusted up and down.

[0013] Furthermore, triangular reinforcing feet are respectively arranged on the front and rear sides of the pillar.

[0014] The utility model installs the camera on a swing mechanism, the swing mechanism is connected to a driving mechanism, and the driving mechanism drives the swing mechanism to rotate, so that the camera is rotated around the speaker product for shooting. In this way, the camera's shooting angle is not blocked, and the shooting blind spot is eliminated. At the same time, because the shooting is from the side and above, the local details of the glue are more clearly identified than from directly above, thereby improving the recognition accuracy of defective products and reducing the defective product rate.
