Description

Technical Field

[0002] Base station antennas, as products of the communications industry, the welding temperature during their processing is the key factor affecting the welding quality. Among them, the linear expansion coefficients of metals and non-metals are inconsistent with different temperatures, and the welding connection structure is one of the main factors for intermodulation instability. Metal and non-metal parts with smaller cross-sectional dimensions relative to length are connected at both ends of the length. The temperature difference between day and night will cause complex internal forces in the parts. This internal force is called stress in the industry. The repeated action of stress will deteriorate the quality of the contact surface, reduce the contact surface pressure, and thus affect the intermodulation test results. In addition, the coaxial cable in the base station antenna is also subject to stress that affects intermodulation due to temperature changes.

The vibration mechanism 20 is connected to the support frame 30, and the vibration mechanism 20 is used to drive the support frame 30 to vibrate back and forth, thereby driving the base station antenna on the support frame 30 to vibrate back and forth. Among them, the vibration direction of the vibration mechanism 20 includes but is not limited to various directions such as the vertical direction, the horizontal direction, and the direction having an angle with the vertical direction. In this embodiment, in order to improve the stability of the base station antenna during the vibration process and prevent it from falling off, the vibration direction specifically selects the vertical direction. In addition, the support frame 30 is connected to the frame 10 through the elastic member 40.

[0027] When the vibration device of the base station antenna is used, the base station antenna is placed on the support frame 30, and the vibration mechanism 20 drives the support frame 30 to vibrate back and forth. Under the elastic buffering effect of the elastic member 40, the support frame 30 vibrates stably, and correspondingly drives the base station antenna thereon to vibrate back and forth, thereby being able to release product stress in advance, improve the reliability of the third-order intermodulation test results of the product, reduce the risk of poor intermodulation, improve the efficiency of zero-antenna product intermodulation testing, and improve product quality. In addition, the degree of automation is high, which can reduce the workload of workers, and the method is simple and easy to operate.

The motor 21 is used to drive the cam 22 to rotate, and the cam 22 and the support frame 30 abut against each other to drive the support frame 30 to vibrate back and forth. In this way, when the motor 21 is working, the motor 21 drives the cam 22 to rotate, and the cam 22 drives the support frame 30 to vibrate back and forth accordingly, thereby driving the base station antenna to vibrate back and forth accordingly.

In this way, in the loading and unloading area 51, the base station antenna is placed on the conveying mechanism 50, and the conveying mechanism 50 conveys the base station antenna to the vibration area 23, and then the lifting mechanism 60 rises, driving the support frame 30 to rise synchronously, and the support frame 30 can lift the base station antenna located on the conveying mechanism 50, and then the vibration mechanism 20 starts to vibrate reciprocatingly to drive the base station antenna to vibrate reciprocatingly; after the vibration times of the base station antenna reaches the requirement, the vibration mechanism 20 stops vibrating and the vibration is completed; the lifting mechanism 60 descends, driving the support frame 30 to descend synchronously, and the base station antenna falls onto the conveying mechanism 50 again, and the base station antenna that has completed the vibration is driven by the conveying mechanism 50 to return to the loading and unloading area 51, unload in the loading and unloading area 51, and then the vibration work of the next base station antenna is carried out.

[0036] See also Figures 2 to 4 In one embodiment, the conveying mechanism 50 includes a stand 52, a transmission element 53 and a rotation power mechanism (not shown in the figure). The transmission element 53 is movably arranged on the stand 52 around the circumference of the ring where it is located, and the rotation power mechanism is connected to the transmission element 53 and is used to drive the transmission element 53 to move. In this way, when the rotation power mechanism is working, it drives the transmission element 53 to move, thereby driving the base station antenna to move back and forth between the loading and unloading area 51 and the vibration area 23.

[0037] In some embodiments, the conveying element 53 includes but is not limited to a conveying chain, a conveying belt, etc. In addition, the number of the conveying elements 53 is not limited to one, and for example, at least two conveying elements 53 are provided, and each conveying element 53 is arranged in parallel, and when in use, the base station antenna can be synchronously moved back and forth between the loading and unloading area 51 and the vibration area 23.

[0040] See also Figure 3 and Figure 4In some embodiments, the vibration device of the base station antenna further includes a control cabinet 70. The control cabinet 70 is electrically connected to the vibration mechanism 20, the rotation power mechanism and the lifting mechanism 60.

[0042] Among them, the base station antenna can be directly placed on the conveying mechanism 50, and moved back and forth between the loading and unloading area 51 and the vibration area 23 under the drive of the conveying mechanism 50; it can also be indirectly placed on the conveying mechanism 50, specifically, for example, it also includes a tooling plate 80 for installing the base station antenna, and a fastener 81 arranged on the tooling plate 80, the fastener 81 fixes the base station antenna on the tooling plate 80, and the conveying mechanism 50 can support and convey the tooling plate 80 so that the tooling plate 80 moves back and forth between the loading and unloading area 51 and the vibration area 23. When the tooling plate 80 drives the base station antenna to move to the vibration area 23, the lifting mechanism 60 rises, driving the support frame 30 to rise synchronously, and the support frame 30 can lift the tooling plate 80 and the base station antenna located on the conveying mechanism 50, and then the vibration mechanism 20 starts to vibrate reciprocatingly to drive the tooling plate 80 and the base station antenna to vibrate reciprocatingly; after the vibration times of the base station antenna reaches the requirement, the vibration mechanism 20 stops vibrating and the vibration is completed; the lifting mechanism 60 descends, driving the support frame 30 to descend synchronously, and the base station antenna falls onto the conveying mechanism 50 again, and the conveying mechanism 50 drives the tooling plate 80 and the base station antenna that have completed the vibration to return to the loading and unloading area 51, unload in the loading and unloading area 51, and then the vibration work of the next base station antenna is carried out.

The closed box 100 is provided with a door and a door opening mechanism connected to the door, and the door opening mechanism is used to drive the door to open or close the door. In this way, after the door is opened by the door opening mechanism, the base station antenna to be vibrated can be sent into the closed box 100, and then the door is closed by the door opening mechanism, and the vibration mechanism 20 can drive the base station antenna to vibrate.

[0047] In one embodiment, the vibration device of the base station antenna further includes a control cabinet 70 and a first sensor. The control cabinet 70 is electrically connected to the first sensor, the door opening mechanism and the vibration mechanism 20 respectively. The first sensor is located inside the closed cavity and is used to sense whether there is a base station antenna on the support frame 30. When the first sensor senses that there is a base station antenna on the support frame 30, the control cabinet 70 controls the door opening mechanism to close the box door and drives the vibration mechanism 20 to vibrate.

In this way, the conveying mechanism 50 can smoothly transfer the base station antenna from the loading and unloading area 51 to the vibration area 23.

[0050] The first sensor and the second sensor are independently configured, including but not limited to various types of sensors such as photoelectric switches.
