[0011] The beneficial effects of the utility model are as follows: the ultrasonic puncture welding equipment designed in this scheme adopts a multi-axis robot with an ultrasonic welding head to perform ultrasonic puncture welding on the products after positioning and fixing. The welding head library in the equipment stores a variety of different types of ultrasonic welding heads. When targeting different types of products, the multi-axis robot can automatically replace the ultrasonic welding head to improve the overall versatility of the equipment.

[0012] Furthermore, the welding head library includes a support frame arranged on the workbench, and a clamping block for fixing the ultrasonic welding head is arranged on the top of the support frame; a plurality of ultrasonic welding heads of different types are stored in the welding head library, and each ultrasonic welding head is suspended on the support frame by its corresponding clamping block, so that the multi-axis robot can pick and place it at any time.

[0013] Furthermore, the card block is U-shaped and has an opening at one end; the card block design with an opening at one end of the U-shape is convenient for a multi-axis robot to pick up and place the ultrasonic welding head, and the welding head can enter and exit the card block through the opening part.

[0014] Furthermore, the positioning mechanism includes a jig block arranged on the welding table, the jig block is provided with a positioning groove, and the product is placed in the positioning groove; the positioning groove provided on the jig block can enable the product to be quickly positioned after being placed on the welding head, ensuring that the positioned product is in a specified position, facilitating the subsequent ultrasonic welding head to directly weld the product, thereby improving welding efficiency; at the same time, the slot can prevent the product from being displaced, thereby effectively improving welding accuracy.
