Description

Technical Field

[0001] The utility model relates to the field of earphone production, in particular to an OWS earphone test automation fixture. Background Art

[0002] In the field of headphones, OWS headphones (open wireless headphones) have been developed recently. Compared with traditional wireless Bluetooth headphones, OWS headphones do not invade the ear canal and are healthier. They cover the outside of the ear canal or near the ear canal. When using open wireless headphones, users can not only communicate with others normally, but also feel safer in sports scenes. Its open listening atmosphere does not affect the perception of the environment. It is more comfortable to wear for a long time than traditional in-ear wireless Bluetooth headphones and bone conduction headphones. Compared with bone conduction, the sound of OWS is conducted by air, and does not require close cooperation between the bone conduction headphones and the wearer. There is no audio quality limit. The sound is heard through the ear canal and the eardrum. It is the most traditional and natural way to listen.

[0003] The existing OWS headset includes a left headset and a right headset. When testing the OWS headset, the microphone needs to be pointed toward the headset. Due to the shape of the OWS headset, the direction of the sound emitted by the headphone jack of the OWS headset is no longer in the same straight line as the microphone. And because the sound of the OWS headset is relatively low, the sound quality and volume of the microphone are reduced when collecting sound.

[0004] Therefore, an OWS headphone test automation fixture is proposed, in which the test element can automatically block the headphone jack of the headphone during the test to collect the sound. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an OWS headphone test automation fixture, comprising: a bottom plate, a substrate, a jig and a detection mechanism, the bottom plate is provided with a detection station and a loading station, the substrate is slidably arranged between the detection station and the loading station, the jig is detachably arranged on the substrate, the upper surface of the jig is provided with a workpiece groove, the end of the lower surface of the jig close to the detection station is provided with a second through groove, the end of the substrate close to the detection station is provided with a third through groove, the workpiece groove and the second through groove are connected through a sound outlet hole, the detection mechanism is arranged at the detection station, the detection mechanism and the workpiece groove are arranged one-to-one, each of the detection mechanisms includes a telescopic device and a detection unit, the upper and lower ends of the telescopic device are respectively arranged on the detection unit and the bottom plate, the telescopic direction of the telescopic device is inclined relative to the sliding direction of the substrate and the plane where the bottom plate is located; when the substrate is located at the detection station, the upper end of the detection unit is arranged in the second through groove, and the detection unit passes through the third through groove.

[0006] Preferably, the above-mentioned OWS headphone test automation fixture also includes a positioning mechanism, which is arranged in a one-to-one correspondence with the workpiece slot, and each of the positioning mechanisms includes a lifting device and a pressing unit, and the upper and lower ends of the lifting device are respectively connected to the bottom plate and the pressing unit, and the pressing unit is arranged above the detection station.

[0007] Preferably, the pressing unit comprises a connecting arm and a pressing block, and the lifting device and the pressing block are respectively connected to two ends of the connecting arm; when the substrate is located at the detection station, the pressing block is arranged directly above the workpiece slot.

[0008] Preferably, the pressing unit also includes a guide rod, which is arranged in the middle of the connecting arm, and the fixture and the substrate are respectively provided with a first hole and a second hole, and the first hole and the second hole correspond one to one and are coaxially arranged; when the substrate is located at the detection station, the guide rod passes through the first hole and the second hole in sequence from top to bottom.

[0009] Preferably, the detection unit comprises a connecting seat and a detection element, the telescopic device and the detection element are detachably arranged at two ends of the connecting seat, respectively, and the detection element comprises a pickup.

[0010] Preferably, the above-mentioned OWS earphone test automation fixture also includes a three-axis manipulator, which is arranged on the bottom plate. The three-axis manipulator includes a plurality of clamping claws, and the clamping claws correspond to the workpiece slots one by one.

[0011] Preferably, the detection element further comprises sound-insulating cotton, a center hole is opened at the center position of the sound-insulating cotton, and the upper end of the pickup is sleeved inside the center hole; when the substrate is located at the detection station, the sound outlet hole is sleeved in the center hole of the sound-insulating cotton.

[0012] Preferably, the above-mentioned OWS headphone test automation fixture also includes a driving device, two ends of which are respectively connected to the bottom plate and the base plate, and the driving device is a pen-shaped cylinder or a linear module.

[0013] Preferably, the lifting device and the telescopic device are both pneumatic cylinders or electric cylinders.

[0014] The working principle of the utility model is as follows: the three-axis manipulator transfers the left earphone and the right earphone from other equipment to the jig. Then the substrate and the jig are moved to the detection station for detection. When the substrate moves to the detection station, the lifting device controls the connecting arm to descend, and the guide column on the connecting arm will pass through the first hole and the second hole in sequence, and the pressure block at the end of the connecting arm presses the left earphone and the right earphone into the workpiece groove. Then the telescopic device extends to send the detection element into the second through groove, and the sound insulation cotton at the upper end of the detection element will conflict with the jig. At this time, the sound outlet will be sleeved in the center hole of the sound insulation cotton. The distance between the detection element and the earphone is reduced, and the sound insulation cotton can concentrate the sound at the position of the detection element. At the same time, the sound insulation cotton is used to isolate the sound to avoid affecting the detection of other earphones.

[0015] The beneficial effect of the utility model is that the telescopic device can be extended to send the detection unit into the second through groove, thereby reducing the distance between the detection unit and the earphone, and ensuring that the volume of the sound collected by the detection unit meets the detection requirements.
