Description

Technical Field

[0001] This utility model relates to the technical field of microphone production equipment, specifically a microphone sorting and testing machine. Background Technology

[0002] A microphone, also known as a transducer, microphone capsule, or microphone tube, is a sound-to-electrical conversion device, that is, a transducer or sensor. Its function is to convert sound signals into electrical signals, the opposite of a speaker. The microphone is the input terminal of a sound device, while the speaker is the output terminal. Common microphone types include dynamic, condenser, electret, and silicon micro-microphones. Microphones are widely used in our lives, for example in various electronic products such as mobile phones, computers, and recording equipment. They are responsible for capturing sound and converting it into electrical signals that the electronic device can process.

[0003] Existing microphone sorting and testing machines typically perform contact tests on microphones that are being transported in real time. However, when feeding microphones, the width of the feeding channel needs to be adjusted according to the different sizes of microphones. Manual adjustment is time-consuming and labor-intensive. In addition, dust easily adheres to the terminals of the microphones during transport, and static electricity may be generated, affecting the test results. Therefore, we have developed a microphone sorting and testing machine. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a microphone sorting and testing machine.

[0024] Combination Figure 1-2 As shown, the present invention provides a microphone sorting and testing machine, comprising: a base 100 and a testing component 200 disposed on the base 100.

[0025] The test assembly 200 includes a storage mechanism mounted on the base 100, a conveying mechanism connected to the storage mechanism, a cleaning mechanism mounted on the storage mechanism, and a test unit 110 mounted on the conveying mechanism. The storage mechanism includes a first limiting plate 210 mounted on the base 100, two sets of storage plates 220 disposed inside the first limiting plate 210, a second limiting plate 230 connected to the first limiting plate 210 and located on the other side of the storage plates 220, and a second guide plate 240 disposed at the bottom of the first limiting plate 210. The conveying mechanism includes a conveying plate 250 connected to the bottom side of the storage plates 220, and a fixed... The positioning plate 260 on the top of the conveying plate 250, the telescopic rod 270 connected to the outside of the conveying plate 250, the fixing plate 280 fixed to the end of the telescopic rod 270 and installed on the base 100, and the spring 290 set on the outside of the telescopic rod 270, together with the testing assembly 200, allow the microphone to be tested to be placed into the positioning plate 260. Under the action of the spring 290, a suitable size is left between the conveying plates 250 for the subsequent microphone to pass through. At the same time, the storage plate 220 connected to the conveying plate 250 also forms a space for storing the microphone. In this way, the material preparation and conveying width can be adaptively adjusted according to the size of the microphone without manual adjustment, which is highly practical.

[0026] Furthermore, the cleaning mechanism includes a mounting bracket 310 installed on the side of the storage plate 220, a through slot 320 formed in the limiting plate 210 for the mounting bracket 310 to pass through, a motor 330 installed on the mounting bracket 310, a rotating shaft 340 fixed to the drive end of the motor 330, a cleaning brush 350 installed on the rotating shaft 340, and a side slot 360 formed in the storage plate 220 for the cleaning brush 350 to pass through. The cleaning brush 350 on the rotating shaft 340 can be rotated by the motor 330. At the same time, the microphone will pass through the cleaning brush 350 when it moves from top to bottom between the storage plates 220. In this way, dust and static electricity on the side of the microphone connection terminal are cleaned, thereby ensuring the accuracy of subsequent tests.

[0027] Specifically, the upper part of the limiting plate 210 and the limiting plate 230 is symmetrically provided with a guide plate 211. The guide plate 211 can make the microphone flow evenly from the middle downward after it is put into the storage plate 220, so as to ensure the stability of the microphone during delivery.

[0028] Furthermore, the testing unit 110 is fixed with a feeding pad 251 located at the bottom of the feeding plate 250. The end of the feeding pad 251 is provided with a discharge groove 252. The feeding pad 251 can protect the microphone. At the same time, the feeding pad 251 is made of rubber to prevent the generation of static electricity. The microphone will continuously flow onto the feeding pad 251 under its own weight. When the microphone moves to the side of the testing unit 110, it can be tested. After the test is completed, the microphone is discharged along the discharge groove 252. It has high practicality.

[0029] It should be noted that a fixing rod 212 is connected between the first limiting plate 210 and the second limiting plate 230. The fixing rod 212 can connect the first limiting plate 210 and the second limiting plate 230, thereby leaving a channel at the bottom of the second limiting plate 230 for the microphone to flow to the feed plate 250.

[0030] Furthermore, a guide rod 213 is fixed to the outside of the storage plate 220 and inserted into the fixing rod 212 to ensure the stability of the storage plate 220.

[0031] The working principle and usage process of this utility model are as follows: First, take out a single microphone product to be tested and place it into the positioning plate 260. Under the action of the spring 290, the feed plates 250 are left with a suitable size for subsequent microphones to pass through. At the same time, the storage plate 220 connected to the feed plate 250 also forms a space for storing microphones. Then, the microphone is placed between the storage plates 220, with the wiring terminals located on the same side of the testing unit 110. The microphone flows downward under its own weight until it moves onto the feed pad 251. When the microphone moves to the side of the testing unit 110, the test terminals of the testing unit 110 are appropriately pushed out to contact the microphone for testing. After the test is completed, the testing unit 110 is reset, and the microphone is discharged along the discharge groove 252 on the feed pad 251 for collection.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
