[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-2 , the embodiment of the present invention includes:

[0021] An angle and discontinuity adjustment device for earphone CAP and HSG enables an operator to more efficiently and accurately adjust the angle and discontinuity of earphone CAP and HSG. Its specific structure includes: a box body, an electrical box, a display, a CCD detection module, an angle adjustment module 1, and a rotatable backlight bracket.

[0022] The electrical box, the CCD detection module, the angle adjustment module, the rotatable backlight bracket and the safety grating are arranged in the box body, the display is connected to the box body, the CCD detection module is arranged on the outside and above the angle adjustment module, and the rotatable backlight bracket is arranged on the side of the angle adjustment module.

[0023] The CCD detection module includes one or more lateral detection modules and one or more top detection modules. The lateral detection module is connected to the box through a lateral positioning device for adjusting the position of the lateral detection module, and the top detection module is connected to the box through a top positioning device for adjusting the position of the top detection module, so as to adjust the detection position of the CCD detection module according to actual needs.

[0024] Among them, the lateral detection modules include CCD12, CCD23, CCD34, CCD45, and the top detection module is CCD56.

[0025] The rotatable backlight bracket includes a bracket base 7, a bearing seat 8, and a bracket body 9. The bracket body is rotatably connected to the bracket base via a rotating shaft and the bearing seat, so that the user can rotate the backlight bracket as needed to adjust the position and angle of the backlight bracket and improve detection accuracy.

[0026] The angle adjustment module includes an adjustment base 10, a bracket 11, an R-axis micrometer 12, an X-axis micrometer 13, a Y-axis micrometer 14, a carrier seat 15, a carrier pressure plate 16, a lifting rail 17, a slider 18, an adjustment plate 19, and a lifting drive mechanism. The bracket is vertically arranged on the adjustment base, the R-axis micrometer, the X-axis micrometer, and the Y-axis micrometer are connected and arranged on the adjustment base from top to bottom in sequence, the carrier seat is arranged on the R-axis micrometer, the lifting rail is arranged on the bracket, the carrier pressure plate is slidably connected to the lifting rail through the slider, the adjustment plate is connected to the carrier pressure plate or the slider, and the lifting drive mechanism is floatingly connected to the adjustment plate through a pressure adjustment spring to drive the carrier pressure plate to move up and down, thereby tightening or loosening the carrier.

[0027] Among them, the R-axis micrometer, the X-axis micrometer, and the Y-axis micrometer can adopt existing devices.

[0028] The carrier pressure plate can be made of silicone pressure plate. The large friction property of silicone can be used to make the carrier pressure plate and the Cap carrier relatively fixed, instead of using pins for direct positioning, to avoid the Cap being crushed when the carrier pressure plate descends to press the Cap (with large angle deviation). In addition, the flexibility of silicone can make the Cap carrier better conform to the Cap to achieve better pressing effect.

[0029] The lifting drive mechanism includes a connecting seat 20, a connecting slot, a connecting shaft 22, and a pressure adjusting handle 23. The connecting seat is floatingly connected to the adjusting plate through a connecting pin and a pressure adjusting spring 24. The lower end of the connecting shaft is connected to the connecting slot on the connecting seat, and the upper end thereof is connected to the pressure adjusting handle. The pressure adjusting handle drives the connecting shaft to move up and down, thereby driving the adjusting plate to move up and down through the connecting seat.

[0030] A process flow for adjusting the angle and gap between the earphone CAP and HSG includes:

[0031] 1. Place the product in the product carrier, use a glue dispenser to dispense glue, and fit the CAP and HSG.

[0032] 2. Fix the glued product carrier on the carrier seat of the angle adjustment module. The product carrier and the carrier seat are detachably connected.

[0033] 3. Adjust the pressure adjustment handle to let the silicone pressure plate press the CAP carrier so that the CAP part and the HSG part of the product fit together. After the carrier pressure plate is pressed tightly, glue overflow will appear at the parting line of the product. The overflow glue needs to be cleaned first to avoid misjudgment caused by the overflow glue affecting the camera capture.

[0034] 4. Adjust the rotating backlight bracket, open the gap, put the angle adjustment module into the device and fix it.

[0035] 5. Use CCD5 to identify and measure the R-axis angle of the product, and make fine adjustments using the knob on the R-axis micrometer.

[0036] 6. After the R-axis is adjusted, the display screen automatically jumps to the X-axis or Y-axis adjustment interface for subsequent adjustments.

[0037] 7. Use CCD2 to identify and measure the product's X-axis break, and make fine adjustments using the knob on the X-axis micrometer.

[0038] 8. Use CCD1, CCD3, and CCD4 to identify and measure the Y-axis misalignment of the product, and use the knob on the Y-axis micrometer to make fine adjustments. CCD4 is the main identification and measurement device for adjusting the Y-axis, and CCD1 and CCD3 are used to obtain and determine the four auxiliary adjustment points of the other two angles.

[0039] 9. Use a silicone pressing plate to press and fix the adjusted product and wait for the glue to solidify. Since the glue takes a long time to solidify, after pressing for a period of time, the product carrier can be removed from the carrier seat and wait for solidification to avoid the machine being in standby mode for a long time and improve efficiency.

[0040] 10. Use a CCD detection camera to shoot and detect, and display the product image, detection results and adjustment data in real time on the display. At the same time, the present invention uses a micrometer to adjust the angle and step difference in the X / Y / R adjustment module. The operator can clearly see all the data and make precise fine adjustments in time, which greatly improves the production efficiency and accuracy. In addition, by adopting visual adjustment, real-time display of product NG or PASS can be achieved, and users can obtain product detection status more clearly, accurately and quickly, thereby improving detection efficiency.

[0041] The beneficial effects of the angle and gap adjustment device for earphone CAP and HSG of the present invention are:

[0042] 1. Use CCD detection module to replace human eyes to complete recognition, measurement, positioning, judgment and other functions, which is more efficient and has lower error;

[0043] 2. Use the angle adjustment module equipped with a micrometer instead of manual adjustment by the operator to achieve more precise fine-tuning of the product;

[0044] 3. Use a pressure regulating spring (the pressure output by the spring can be adjusted according to demand) and a silicone pressure plate to ensure that the product will not be damaged.

[0045] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
