AI Technical Summary
The printing angle of the characters on the left and right ear buttons of existing headphones is difficult to detect accurately, resulting in incorrect printing direction and mixed materials, which is inefficient and costly.
A device for detecting the angle of printed characters on the left and right ear buttons of a headset was designed. It uses a first CCD camera and a second CCD camera for front and side detection, and combines X-axis and Y-axis motion servo modules to realize the automatic identification and adjustment of the product on the button fixture.
It improved the accuracy and efficiency of testing, reduced labor costs, ensured the correct clamping and material handling of products, and improved production quality.

Abstract
Claims
1. A headphone left and right ear button printed character angle detection device, characterized in that, include: A frame, on which a work platform is provided; A gantry fixing bracket is provided on the working platform; X-axis moving servo module, the X-axis moving servo module is horizontally fixed along the length direction of the top crossbeam of the gantry fixed bracket; A first CCD camera and a second CCD camera are provided with camera mounting brackets. The camera mounting brackets are connected to an X-axis motion servo module. The X-axis motion servo module drives the camera mounting brackets to move along the X-axis. The imaging lens of the first CCD camera faces a first angle, and the imaging lens of the second CCD camera faces a second angle. The Y-axis motion servo module is fixed on the working platform along the central axis of the gantry fixed bracket, and the Y-axis motion servo module is provided with a clamp fixing seat for fixing the button clamp.
2. The headphone left and right ear button printed character angle detection apparatus according to claim 1, characterized by, The X-axis motion servo module uses a first linear slide, and the first slide on the first linear slide is connected to a camera mounting bracket. The Y-axis motion servo module uses a second linear slide, and the second slide on the second linear slide is connected to a clamp mounting bracket.
3. The headphone left and right ear button printed character angle detection apparatus according to claim 2, characterized by, The camera mounting bracket includes a vertical mounting plate and a horizontal mounting plate connected to the lower end of the vertical mounting plate. A connecting plate is vertically provided on the back of the vertical mounting plate, and the connecting plate is connected to the first slide. The first CCD camera is mounted on the vertical mounting plate, and the second CCD camera is fixed on one side of the horizontal mounting plate. The first angle is vertically downward, and the second angle is obliquely downward towards the left or right side of the clamp mounting base.
4. The headphone left and right ear button printed character angle detection apparatus according to claim 3, characterized by, Near the lower end of the vertical fixing plate is a ring light source coaxial with the shooting lens of the first CCD camera, and a strip light source is provided on the same side of the horizontal fixing plate as the second CCD camera.
5. The headphone left and right ear button printed character angle detection apparatus according to claim 3, characterized by, The upper half of the front side of the vertical fixing plate has a row of first screw holes arranged along the length of the vertical fixing plate on both sides. The bottom of the first CCD camera is provided with a fixing seat, and the two sides of the fixing seat are provided with stepped holes. By adjusting the connection between the stepped holes and the first screw holes at different positions, the position of the first CCD camera can be adjusted up and down.
6. The headphone left and right ear button printed character angle detection apparatus according to claim 5, characterized by, The vertical fixing plate has a rectangular protrusion in the middle along its length, and the bottom of the fixing seat has a groove that is embedded in the rectangular protrusion. The rectangular protrusion serves as a guide for the fixing seat to move up and down.
7. The headphone left and right ear button printed character angle detection apparatus according to claim 4, characterized by, The lower half of the front of the vertical fixing plate has a rectangular groove along its length. Near the two sides of the bottom of the rectangular groove, there is a row of second screw holes arranged along the length of the rectangular groove. The ring light source has a ring bracket. The rear side of the ring bracket is a rectangular fixing plate that extends backward and bends upward at 90 degrees. The rectangular fixing plate is embedded in the rectangular groove. The two sides of the rectangular fixing plate have holes that mate with the second screw holes. By adjusting the holes of the rectangular fixing plate to connect with the second screw holes at different positions, the vertical position of the ring light source can be adjusted.
8. The headphone left and right ear button printed character angle detection apparatus according to claim 7, characterized by, On the side of the horizontal fixing plate that connects to the vertical fixing plate, there is a long slot along the length of the horizontal fixing plate. The long slot is connected to the second screw hole. The long slot is used to adjust the left and right movement position of the horizontal fixing plate and the vertical fixing plate. By connecting the long slot to the second screw hole at different positions, the up and down position of the second CCD camera can be adjusted.
9. The headphone left and right ear button printed character angle detection apparatus according to claim 4, characterized by, The vertical fixing plate has multiple spaced third screw holes on its left and right side walls. The strip light source has an L-shaped fixing bracket. One end of the L-shaped fixing bracket is fixed to the strip light source, and the other end is fixed with a hole and a third screw hole by screws. By fixing it to different third screw hole positions, the vertical position of the strip light source can be adjusted.
