[0033] Specifically, the antenna card cover 16 comprises a disc 161, a plurality of supporting strips 162 and a plurality of pressing strips 163, the disc 161 is used for abutting against the upper end of the low-frequency vibrator 17 and the second knob 155, and the pressing strips 163 are used for abutting against the lower end of the low-frequency vibrator 17; the number of the supporting strips 162 is consistent with that of the pressing strips 163, one end of each of the supporting strips 162 is connected to the circumference of the disc 161, and the other end of each of the supporting strips 162 is connected to the pressing strips 163; the pressing strips 163 are provided with a plurality of pressing blocks 164 for abutting the antenna against the low-frequency vibrator 17.

[0035] In actual use, the loading mechanism of the automatic welding machine in the embodiment is installed in an ultrasonic welding machine which is also provided with an ultrasonic welding mechanism 2 for ultrasonic welding of the low-frequency vibrator and the antenna in the embodiment. An external manipulator clamps and places the low-frequency vibrator 17 in the positioning groove 152 of the positioning seat 151. Since the shape of the positioning groove 152 corresponds to the shape of the low-frequency vibrator 17, the low-frequency vibrator 17 is fixed in the positioning groove 152 by abutting the first knob 154 against the low-frequency vibrator 17 after twisting the first knob 154, thereby preventing the low-frequency vibrator 17 from falling during rotation of the loading platform 15. After the low-frequency vibrator 17 is installed, the antenna is clamped and placed in the corresponding position of the low-frequency vibrator 17 by the external manipulator, and the antenna cover 16 is placed on the low-frequency vibrator 17 by the manipulator. The disc 161 of the antenna cover 16 abuts against the upper end of the low-frequency vibrator 17, the pressing strip 163 of the antenna cover 16 abuts against the lower end of the low-frequency vibrator 17, and the pressing block 164 of the antenna cover 16 presses the antenna against the low-frequency vibrator 17. Then, the second knob 155 is rotated to abut against the disc 161, so that the antenna cover 16 is completely fixed on the low-frequency vibrator 17, thereby ensuring the fixation of the antenna and the low-frequency vibrator 17, and further ensuring that the antenna will not be separated from the low-frequency vibrator 17 during rotation of the loading platform 15. After the above steps are completed, the first rotation driving mechanism 13 is controlled to drive the swing platform 112 to rotate at different angles, the second rotation driving mechanism 14 is controlled to drive the loading platform 15 to rotate, and the loading transverse driving mechanism 12 is controlled to drive the loading device 11 to transversely move, so as to realize arbitrary control of the low-frequency vibrator 17 in three different directions, and then the ultrasonic welding mechanism 2 is moved to ultrasonically weld the antenna at different positions of the low-frequency vibrator 17.

[0036] In addition, the swing platform 112 can be controlled to rotate by controlling the extension or retraction of the linear cylinder 131. In addition, the over-retraction of the linear cylinder 131 can be prevented by the limiting plate 132 and the top piece 134, thereby avoiding damage of the linear cylinder 131.

[0037] It should be noted that the loading transverse driving mechanism 12 is a driving mechanism composed of a motor, a synchronous wheel, a synchronous belt and a sliding block, and the second rotation driving mechanism 14 is a driving mechanism composed of a motor, a synchronous wheel and a synchronous belt. The principle of how the loading transverse driving mechanism 12 drives the loading device 11 to transversely move and the principle of how the second rotation driving mechanism 14 drives the loading platform 15 to rotate can be referred to the prior art, which will not be described herein.

[0038] In the embodiment, the number of loading mechanisms 1 is two, so two ultrasonic welding mechanisms 2 are also installed in the ultrasonic welding machine, one ultrasonic welding mechanism 2 and one loading mechanism 1 correspond to a group, and the two low-frequency vibrators 17 and the antenna can be simultaneously ultrasonic welded, thereby increasing the welding efficiency.

[0039] In conclusion, the loading mechanism of the automatic welding machine has the following effects:

[0040] The problem that the low-frequency vibrator cannot be welded at multiple angles is solved: the loading mechanism of the automatic welding machine is provided with the loading device 11 and the loading horizontal movement driving mechanism 12, the loading horizontal movement driving mechanism 12 drives the low-frequency vibrator 17 to move linearly, and the loading device 11 is used for placing the low-frequency vibrator 17 and driving the low-frequency vibrator 17 to move angularly, so that the antenna is ultrasonic welded with the low-frequency vibrator 17 at different positions on the low-frequency vibrator 17 by the ultrasonic welding mechanism 2.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
