A horizontal positioning mechanism for ultrasonic welding equipment, as shown in Figure 1 and Figure 2, includes a conveyor belt 1, on which a double-station carrier 2 that moves along its conveying direction is provided, and on the conveyor belt 1 is provided with a pair of The double-station carrier 2 realizes the first positioning mechanism 4 for horizontal positioning. This solution increases the production efficiency of a single production line by more than five times, and the input and output ends of the base material maintain a constant and uninterrupted conveying work, so that the front and rear processes of the production line that cooperate with the ultrasonic welding machine are not affected, and the welding quality is stable. That is, after loading, it is conveyed by the conveyor belt 1. When the double-station carrier 2 reaches the designated position (below the ultrasonic welding head), the first positioning mechanism 4 will realize the horizontal positioning of the double-station carrier 2 without manual assistance. , The angle can be adjusted to the welding station, greatly improving production efficiency and reducing labor costs.

As shown in Figures 1 and 2, the first positioning mechanism 4 includes a cylinder 41 that is arranged on one side of the double-station carrier 2 and is fixed on the conveyor belt 1 through a mounting bracket. The end of the piston rod of the cylinder 41 is provided with a The first abutment 42 matched with the carrier 2, and the other side of the double-station carrier 2 opposite to the cylinder 41 is provided with a motor 43 fixed on the conveyor belt 1 through a mounting bracket, and the end of the output shaft of the motor 43 is provided with The gear 44 is meshed with a rack 45 , and the rack 45 is connected with a second abutting member 46 matched with the double-station carrier 2 through the limiting member 5 .
