After continuous research and design and repeated trial production and improvement, the utility model with practical value is finally created.

Referring to fig. 1 to 13, an embodiment of the utility model provides an automatic testing apparatus for an earphone, including a carrier 1, a conveying mechanism 2, a feeding mechanism 3, a rotation testing mechanism 4, a discharging mechanism 5, and a frame 6; wherein,

the conveying mechanism 2, the feeding mechanism 3, the rotary testing mechanism 4 and the blanking mechanism 5 are all arranged on the rack 6, the feeding mechanism 3 is positioned at the feeding end of the conveying mechanism 2, and the blanking mechanism 5 is positioned at the discharging end of the conveying mechanism 2;

the carrier 1 is used for loading a charging box to be tested or tested and an earphone;

the conveying mechanism 2 is used for conveying a carrier 1 loaded with a charging box to be tested or tested and earphones;

the feeding mechanism 3 is used for transferring the carrier 1 loaded with the charging box and the earphones to be tested from the conveying mechanism 2 to the rotary testing mechanism 4;

the rotary testing mechanism 4 is used for testing a charging box and an earphone to be tested which are loaded on the carrier 1;

the blanking mechanism 5 is used for transferring the carrier 1 loaded with the tested charging box and the earphone from the rotary testing mechanism 4 to the conveying mechanism 2.

It should be noted that, this embodiment is through integrating transport mechanism 2, feed mechanism 3, rotatory accredited testing organization 4 and unloading mechanism 5 in frame 6, then improve scattered manual line multiplex station mode for automatic complete machine simplex station mode for charge box and its earphone can accomplish whole test procedure on an equipment voluntarily, thereby make test procedure no longer be the bottleneck process that whole line efficiency was pulled up, solved test time long, inefficiency, the intensive problem of manpower.

In the present embodiment, the rotary testing mechanism 4 includes a rotary indexing disc 41, an electrical slip ring 42, a testing ram 43 and a probe seat 44;

a plurality of test positions for placing the carrier 1 loaded with the charging boxes and the earphones to be tested are arranged on the rotary indexing disc 41 at equal intervals along the circumferential direction of the rotary indexing disc 41;

the number of the test indenters 43 corresponds to the number of the test positions one by one, and each test indenter 43 is arranged on the rotary indexing disc 41 and is respectively positioned above the corresponding test position;

the electric slip ring 42 is arranged on the rotary indexing disc 41, and the axis of the electric slip ring 42 and the axis of the rotary indexing disc 41 are on the same straight line;

the number of the probe seats 44 corresponds to the number of the test sites one by one, and each probe seat 44 is arranged on the rotary indexing disc 41 and is respectively positioned on the corresponding test site;

the electrical slip ring 42 is connected to the test indenter 43 and the probe holder 44 by connection wires, respectively.

It should be noted that, because the rotary indexing disc 41 in this embodiment is provided with a plurality of test positions, and each test position can be placed by one carrier 1, a plurality of sets of charging boxes and earphones can be tested on the rotary indexing disc 41 at the same time, so that the test time is divided, and the test efficiency is further improved. In addition, each test position is provided with a positioning column, and the corresponding carrier 1 is provided with a positioning hole, so that the carrier 1 can be stably placed on the test position.

It can be understood that the rotary indexing disc 41 is controlled by a stepping motor at the bottom to rotate, and rotates an angle every set time period, that is, the carrier 1 is rotated by the rotary indexing disc 41 from the beginning of being transferred to the test position by the feeding mechanism 3, and the rotary indexing disc 41 keeps the test pressure head 43 and the charging box and the earphone on the carrier 1 in the power-on test state during the rotation process until the charging box and the earphone complete the test operation and output the test result, at which time the carrier 1 just completes the full rotation, and then the discharging mechanism 5 is transferred to the conveying mechanism 2.

For convenience of understanding, the present embodiment sets the number of test sites to 12 as an example, and sets the stepping motor to drive the rotary index plate 41 to automatically rotate 30 ° every 3 seconds, and each carrier 1 on the test site will rotate through 12 degrees, i.e. 360 °. Each test position is close to the feeding mechanism 3 and then serves as a feeding position for the feeding mechanism 3 to grab and place the carrier 1 on the feeding mechanism, and similarly, each test position is close to the discharging mechanism 5 and then serves as a discharging position for the discharging mechanism 5 to grab and place the carrier 1 on the conveying mechanism 2.

The electrical slip ring 42 is connected to a power source, which in turn can supply electrical power to the test indenter 43 and the probe mount 44 via connection wires. Specifically, the test indenter 43 and the probe holder 44 are respectively provided with 4 probes, and each probe is connected with the electrical slip ring 42 and keeps being electrified. The 4 probes on the test pressure head 43 correspond to the contacts on the left and right earphone chambers respectively, and the 4 probes on the probe base 44 correspond to the contacts on the left and right earphones respectively.

In this embodiment, the carrier 1 is provided with a charging box slot 11 with a hollowed-out slot bottom for accommodating a charging box and an earphone slot 12 for accommodating an earphone;

the probe base 44 passes through the hollowed bottom of the earphone slot 12, and then contacts and is conductively connected with the contact of the earphone loaded in the earphone slot 12 through a probe.

It should be noted that, after the earphone is mounted in the earphone slot 12 of the carrier 1, the contact point on the earphone is generally downward because the earphone is downward, and therefore, the probe of the probe holder 44 needs to contact the contact point on the earphone from bottom to top. Of course, different design considerations may also lead to the possibility of the probe coming into contact with the contacts on the headset from other directions, such as up or left and right; wherein if it is an upper one, it is contemplated to eliminate the probe holder 44 and use another test ram 43 like a charging box to make contact with the contacts on the headset. It can be understood that, in order to stably accommodate the earphones in the earphone slot 12, an earphone accommodating block 13 is arranged in the earphone slot 12, and two earphone accommodating slots corresponding to the left and right earphones, which are the same as those on the charging box, are formed on the earphone accommodating block 13. The bottom of the earphone receiving block 13 is in contact with the probe holder 44, and then the probe of the probe holder 44 is in contact with the earphone contact through the earphone receiving groove.

In this embodiment, the rotary testing mechanism 4 further includes a code scanning gun 45;

the code scanning gun 45 is arranged below the rotary indexing disc 41;

a notch 46 is formed in the position, corresponding to the charging box slot 11, of the testing position;

the code scanning gun 45 scans the digital code at the bottom of the charging box through the notch 46 and the hollowed-out bottom of the charging box slot 11 to activate the test program.

It can be understood that the scanning direction of the code scanning gun 45 is aligned with the notch 46, when the loading mechanism 3 places the carrier 1 loaded with the charging box and the earphone on the testing position of the rotary dividing plate 41, the code scanning gun 45 located below can scan the digital code at the bottom of the charging box through the notch 46 and the hollowed-out groove bottom of the charging box groove 11 to activate the testing program, and thus the functions of binding the charging box with the earphone by MES, detecting the electric quantity of the charging box, setting the low power consumption mode of the charging box, setting the shipping mode of the earphone and the like are completed.

In this embodiment, the testing ram 43 comprises a liftable testing frame 431, a charging box testing ram 432 and an earphone fixing ram 433;

the test frame 431 is disposed on the rotary index plate 41;

the charging box testing pressure head 432 and the earphone fixing pressure head 433 are both arranged on the testing frame 431 and are positioned above the testing position;

the charging box pressure testing head 432 is in contact with and in conductive connection with a contact of a charging box loaded in the charging box slot 11 through a probe.

It should be noted that the testing frame 431 is mounted on the rotary dividing plate 41 through 6 hexagon socket head cap screws, and may be composed of a bar-shaped cylinder, a shaft lever, a shaft sleeve, and a connecting plate, etc., to drive the charging box testing pressure head 432 and the earphone fixing pressure head 433 to ascend and descend.

Because the contacts of the earphone are contacted and connected from the lower part, in order to prevent the rotary dividing plate 41 from driving the carrier 1 to slightly shift in the rotating process, so that the fault that the contact between the probe and the contacts is poor occurs, preferably, a pressing buffer member, such as a sponge, is sleeved on the earphone fixing pressure head 433, and the pressing buffer member can play a role in pressing and fixing. In addition, when the earphone fixing pressure head 433 presses the earphone, the pressing force can be further controlled by the pressure sensor, so that the earphone and the charging box are not subjected to rigid impact, and the earphone and the charging box are protected from being crushed.

In this embodiment, the feeding mechanism 3 and the discharging mechanism 5 are both manipulators. Of course, the type of the manipulator is not limited in this embodiment as long as the carrier 1 can perform the grabbing function, and generally includes an air cylinder and a clamp. Because the manipulator has good motion precision, consequently can transfer carrier 1 steadily accurately, the manipulator can continuous work moreover, and to a great extent has saved the labour, has improved the efficiency of software testing of box and earphone that charges.

In this embodiment, the automatic testing equipment for earphones further comprises a defective product conveying mechanism 7;

the defective product conveying mechanism 7 is arranged on the rack 6 and is positioned at the discharge end of the conveying mechanism 2;

the blanking mechanism 5 is also used for transferring the carrier 1 loaded with the charging box and/or the earphone which is unqualified to be tested from the rotary testing mechanism 4 to the defective product conveying mechanism 7.

It should be noted that the present embodiment exemplifies that the conveying mechanism 2 and the defective product conveying mechanism 7 share one blanking mechanism 5, but it can be understood that one blanking mechanism 5 may be provided, if necessary.

It should be noted that the conveying mechanism body 21 may include a motor, a transmission mechanism and a conveying chain, such as an endless speed-multiplying chain, so that the middle of the conveying mechanism body 21 has a space for the blocking mechanism 22 to lift. The blocking mechanism 22 can comprise a driving mechanism and a blocking plate or a blocking strip arranged on the movable end of the driving mechanism, when the test position needs to be loaded, the blocking mechanism 22 at the feeding end of the conveying mechanism 2 is lifted to block the carrier 1 conveyed on the conveying mechanism body 21, and then the loading mechanism 3 automatically clamps the carrier 1 loaded with the charging box and the earphone to be tested and places the carrier on the test position. Similarly, when the test position needs to be unloaded, the blocking mechanism 22 at the discharge end of the conveying mechanism 2 is lifted to block the carrier 1 conveyed on the conveying mechanism body 21, and then the unloading mechanism 5 automatically clamps the carrier 1 with the tested charging box and the earphone and places the carrier on the conveying mechanism 2 or the defective product conveying mechanism 7.
