Description

Technical Field

[0001] The utility model relates to the field of antenna production equipment, in particular to a testing device for antenna terminals. Background Art

[0002] Nowadays, with the booming development of the Internet of Things era and the gradual integration of 5G communication technology into people's daily lives, the high speed and convenience it brings have brought a brand new communication experience. The outstanding performance of network equipment and the continuous advancement of high-speed communication technology have further stimulated people's desire and expectations for high-speed communication, and the frequency of antenna use has increased day by day.

[0003] For example, a CPE-5G directional double-sided antenna disclosed in the Chinese utility model patent with publication number CN218385743U, and an FPC antenna for router 2.4G and 5.8G frequency bands disclosed in the Chinese utility model patent with publication number CN207009658U. Such antenna terminals usually include an antenna substrate, a radiation unit is arranged on the antenna substrate, a cable is welded and connected to the antenna substrate, and the other end of the cable is connected to an IPEX terminal. Similar antenna terminals are widely used in WiFi / GPS.

[0004] When manufacturers produce similar antenna terminal products, they find that the antenna terminal products such as Figure 1 As shown, since the IPEX terminal has a direction, when the welding machine welds the cable and the antenna substrate, there is a possibility that the direction of the IPEX terminal will be skewed after welding. Therefore, it is also necessary to detect whether the IPEX terminal is skewed on the welded antenna terminal, and for the completed antenna terminal, it is also necessary to perform a standing wave ratio (VSWR, Working Voltage Standing Wave Ratio) test. Currently, most manufacturers use manual observation to see whether the direction of the welded IPEX terminal is skewed, and then operate the standing wave ratio test equipment to test the IPEX terminal. However, there is a possibility of misjudgment when workers observe whether the direction of the IPEX terminal is skewed, and manual observation is heavy work. As the working time increases, this possibility will increase further, which is not conducive to the quality control of antenna products. Utility Model Content

[0021] The automated antenna terminal testing device of the utility model has a high degree of automation. By integrating a flipping mechanism, a visual inspection mechanism, a transfer mechanism and a standing wave ratio inspection mechanism, a fully automated process of antenna terminals from feeding after welding production to testing and then sorting qualified and unqualified products is realized, which greatly reduces the need for manual intervention, reduces labor intensity and improves production efficiency.

[0022] The visual inspection mechanism uses a CCD camera for visual inspection, which can accurately detect whether the direction of the IPEX terminal is correct and determine whether the welded IPEX terminal is skewed.
