[0002] The mid-frame of a smartphone is a crucial component, requiring it to pass numerous tests before being sent downstream for further assembly. Audio testing is one of these tests.

[0003] In related technologies, materials need to be manually retrieved from the loading conveyor and placed into the test fixture of the audio testing machine. After the audio test is completed, they are then manually removed and placed into the unloading conveyor. This loading and unloading process is inefficient, affecting testing efficiency. Furthermore, loading and unloading require separate conveyor mechanisms, which occupy too much space. Utility Model Content

To this end, this invention proposes an automated loading and unloading device for mobile phone mid-frames and an audio testing device, which can improve loading and unloading efficiency, enhance testing efficiency, and reduce space occupation.

The fixed block and the fixed plate can move relative to each other in a direction perpendicular to the conveying direction and fix their current positions to adjust the relative distance between the push block and the first guide rod. The push block can better cooperate with the first guide rod to clamp and position the mobile phone frame, which is beneficial for adapting to the positioning of mobile phone frames of different sizes.

[0012] In one embodiment of this implementation, the fixture assembly includes two guide bars, one of which is connected to one end of the first guide rod and the other is connected to one end of the second guide rod.

[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an audio testing device 1000 according to one embodiment of the present invention. The present invention provides an audio testing device 1000, which includes an audio testing machine 200 and an automated mobile phone frame loading and unloading device 100 provided in this embodiment. By incorporating the automated mobile phone frame loading and unloading device 100 provided in this embodiment into the audio testing device 1000, the audio testing device 1000 has higher testing efficiency and can reduce space occupation.

[0030] The following is a detailed description of the automated loading and unloading device 100 for the mobile phone mid-frame in the audio testing equipment 1000.

[0031] Please see Figure 1 The automated mobile phone frame loading and unloading device 100 includes a transport mechanism 10, a limiting mechanism 20, and a loading / unloading mechanism 30. The transport mechanism 10 drives the mobile phone frame to move along the conveying direction. The limiting mechanism 20 is mounted on the transport mechanism 10 and can abut against the mobile phone frame in the conveying direction, causing the mobile phone frame to stop upstream. The loading / unloading mechanism 30 picks up the mobile phone frame upstream of the limiting mechanism 20 and transfers it to an audio testing machine 200 for audio testing, and also picks up the mobile phone frame that has completed audio testing on the audio testing machine 200 and transfers it downstream of the limiting mechanism 20.

[0032] Specifically, the conveying direction of the transport mechanism 10 is horizontal. The loading and unloading mechanism 30 can pick up the mobile phone frame by means of adsorption, clamping, etc.

[0033] By setting up a loading / unloading mechanism 30 and a limiting mechanism 20 on the transport mechanism 10, the limiting mechanism 20 can abut against the mobile phone frame in the conveying direction, so that the mobile phone frame stops upstream. The loading / unloading mechanism 30 can pick up the mobile phone frame from upstream of the limiting mechanism 20 and transfer the mobile phone frame to the audio testing machine 200 for audio testing, and pick up the mobile phone frame that has completed audio testing on the audio testing machine 200 and transfer the mobile phone frame to the downstream of the limiting mechanism 20, thereby realizing automated loading / unloading for audio testing. Compared with manual loading / unloading, it has higher loading / unloading efficiency and is conducive to improving testing efficiency. At the same time, since the loading / unloading of the mobile phone frame is realized through a single transport mechanism 10, the space occupation is effectively reduced.

[0034] In one embodiment of this implementation, please refer to Figure 1 The limiting mechanism 20 includes a mounting bracket 21 and a fixture assembly 22. The mounting bracket 21 is fixed to the transport mechanism 10, and the fixture assembly 22 is mounted on the mounting bracket 21 and located on the top side of the transport mechanism 10 so as to abut against the mobile phone frame. This arrangement allows the fixture assembly 22 to be suspended above the transport mechanism 10, reducing the possibility of interference between the fixture assembly 22 and the transport mechanism 10. The fixture assembly 22 can abut against the mobile phone frame in the transport direction.

[0035] Specifically, there are two jig components 22 so that the mobile phone mid-frames can be arranged in two rows so that the loading and unloading mechanism 30 can pick up the two mobile phone mid-frames simultaneously.

[0036] In one embodiment of this implementation, please refer to Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the limiting mechanism 20 in the audio testing equipment 1000 is shown. To guide and limit the movement of the phone's mid-frame, the fixture assembly 22 includes a limiting block 221, a first guide rod 222, and a second guide rod 223. The first guide rod 222 and the second guide rod 223 are disposed opposite each other on the mounting bracket 21 and are used to guide the phone's mid-frame. The limiting block 221 is disposed on the first guide rod 222 and / or the second guide rod 223 and is used to abut against the phone's mid-frame. It is understood that the first guide rod 222 and the second guide rod 223 can abut against the two sides of the phone's mid-frame respectively to ensure that the phone's mid-frame can be driven to a preset position along the conveying direction. Then, the limiting block 221 abuts against the phone's mid-frame, allowing the phone's mid-frame to remain at the preset position for easy loading / unloading mechanism 30 to pick up the material.

[0037] Specifically, the limiting block 221 can be disposed on the first guide rod 222, the second guide rod 223, or both. In this embodiment, the limiting block 221 is fixed to one end of the first guide rod 222.

[0038] Specifically, the limit block 221 is equipped with a fiber optic sensor, which can detect whether a mobile phone frame is in contact with the limit block 221, so as to facilitate the automated loading and unloading mechanism 30.

[0039] In one embodiment of this implementation, please refer to Figure 2 The fixture assembly 22 includes a translation driver 224 and a push block 225. The translation driver 224 is mounted on the second guide rod 223 and connected to the push block 225. The translation driver 224 drives the push block 225 to push the phone frame towards the first guide rod 222. Under the drive of the translation driver 224, the push block 225, the first guide rod 222, and the limiting block 221 can surround and clamp the phone frame, ensuring that the phone frame is in a preset position to facilitate accurate material handling by the loading and unloading mechanism 30.

[0040] Specifically, the fixture assembly 22 includes a fixed plate 226 and a fixed block 227. The translation driver 224 is mounted on the fixed plate 226, and the fixed block 227 is fixed on the second guide rod 223. The fixed block 227 and the fixed plate 226 can move relative to each other in a direction perpendicular to the conveying direction and fix their current positions to adjust the relative distance between the push block 225 and the first guide rod 222. The push block 225 can better cooperate with the first guide rod 222 to clamp and position the mobile phone frame, which is beneficial for adapting to the positioning of mobile phone frames of different sizes.

[0041] Specifically, push block 225 is located downstream of second guide rod 223.

[0042] In one embodiment of this implementation, please refer to Figure 2 The fixture assembly 22 includes two guide bars 228. One guide bar 228 is connected to one end of the first guide rod 222, and the other guide bar 228 is connected to one end of the second guide rod 223. The two guide bars 228 form a tapered opening 2281, which assists the phone's mid-frame in entering between the first guide bar 228 and the second guide bar 228. This arrangement allows for better guidance of the phone's mid-frame.

[0043] Specifically, the guide bar 228 is rotatably connected to the first guide rod 222, and the guide bar 228 is rotatably connected to the second guide rod 223, so as to adjust the taper of the tapered opening 2281 and improve versatility.

[0044] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The transport mechanism 10 includes a support frame 11, a conveyor belt 12, and a rotary driver (not shown). The rotary driver is mounted on the support frame 11, and the conveyor belt 12 is rotatably mounted on the support frame 11 and connected to the rotary driver. The mounting frame 21 is fixed on the support frame 11. This configuration allows for the transport of the phone's mid-frame along the transport direction, and the conveying characteristics of the conveyor belt 12 enable it to continue feeding the phone's mid-frame downstream of the fixture assembly 22 even when the fixture assembly 22 stops it.

[0045] Specifically, the jig assembly 22 is suspended above the conveyor belt 12 to avoid interference.

[0046] In one embodiment of this implementation, please refer to Figure 1 and Figure 3 , Figure 3 yes Figure 1 This is a schematic diagram of the loading / unloading mechanism 30 in the audio testing equipment 1000. The loading / unloading mechanism 30 includes a motion module 31 and two sets of suction components 32. The motion module 31 is connected to the two sets of suction components 32. The motion module 31 is used to drive one set of suction components 32 to place the mobile phone frame onto the audio testing machine 200, and to drive the other set of suction components 32 to pick up the mobile phone frame from the audio testing machine 200 to complete the audio test. With this configuration, the two sets of suction components 32 can alternately load and unload the audio testing machine 200, which helps to improve testing efficiency.

[0047] Specifically, the motion module 31 is constructed as a six-axis robot, which can drive two sets of adsorption components 32 to move in six directions.

[0048] In one embodiment of this implementation, please refer to Figure 3 The loading and unloading mechanism 30 includes a connecting member 33, with two sets of adsorption components 32 disposed on opposite sides of the connecting member 33. The connecting member 33 is connected to a motion module 31, which can drive the connecting member 33 to rotate, thereby swapping the positions of the two sets of adsorption components 32. With this configuration, after one set of adsorption components 32 picks up the tested phone frame, the motion module 31 drives the connecting member 33 to rotate both sets of adsorption components 32, allowing the other set of adsorption components 32 to place the phone frame to be tested onto the audio testing machine 200. This results in high loading and unloading efficiency.

[0049] In one embodiment of this implementation, please refer to Figure 3The adsorption component 32 includes two mounting blocks 321 and two sets of suction nozzles 322. The two mounting blocks 321 are mounted on the same side of the connecting member 33, and the two sets of suction nozzles 322 are respectively set on the corresponding mounting blocks 321 and used to pick up different mobile phone frames. This enables simultaneous loading and unloading at two stations, further improving loading and unloading efficiency and matching the dual-station testing mode of the audio testing machine 200.

[0050] Specifically, two mounting blocks 321 of one adsorption component 32 are mounted on the top side of the connecting member 33, and two mounting blocks 321 of the other adsorption component 32 are mounted on the bottom side of the connecting member 33.

[0051] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
