Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of welding device, and particularly relates to a tap welding device of quadrature mode duplexer. BACKGROUND

[0002] The duplexer is a main accessory of a heterodyne duplex radio station and a relay station, and its function is to isolate the transmitting and receiving signals to ensure that the receiving and transmitting can work normally at the same time. The duplexer is composed of two groups of band-pass filters with different frequencies to avoid the transmission of the local transmitting signal to the receiver.

[0003] In the manufacturing process of the duplexer, the welding of the tap and related components is a crucial link.

[0004] In the prior art, in the process of welding the tap and the duplexer, the position of the tap to be welded needs to be transported, so as to facilitate the welding operation. First, for taps with different weights and shapes, the traditional conveying device is difficult to control the sliding speed of each type of tap individually, resulting in uncontrollable sliding speed of the tap. Such uncontrollable sliding speed not only may cause damage to the surface of the duplexer, but also may affect the quality of the tap itself, thereby reducing the performance of the entire duplexer. The existing conveying device cannot accurately control the sliding speed of each type of tap, and is prone to cause collision between the tap and the duplexer, resulting in unstable welding quality.

[0005] In addition, the existing welding device is prone to jamming when dealing with special-shaped taps, which affects the smoothness of the welding process. The special-shaped tap may be jammed in the conveying device due to the special shape, posture or uneven weight, resulting in interruption of welding and the need for manual intervention to solve the problem, which not only reduces the production efficiency, but also increases the production cost.

[0158] Specifically, in the process of use, the detection camera 264 always observes the state of the part tap in the falling process to ensure that the part tap can smoothly fall.

[0159] The storage groove 262 is located at one end of the rotating part 270 close to the conveying belt 131.

[0160] In the initial state, the storage groove 262 is located in the conveying belt 131 and below the upper conveying belt 131.
