Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Referring to fig. 1 to 4, an embodiment of the present invention provides an ultrasonic metal welding machine for wire harnesses and terminals, including a welding head 10, a first driving mechanism 20 for controlling the vertical movement of the welding head 10, a pressing device 30, and a positioning jig 40 for positioning a terminal 51 of a workpiece 50 located below the welding head 10, wherein the pressing device 30 includes a movable seat 31, a second driving mechanism 32 for driving the movable seat 31 to vertically move, and two pressing members 33 for pressing the wire harnesses, the two pressing members 33 are disposed on the movable seat 31, the two pressing members 33 are disposed oppositely and located on left and right sides of the welding head 10, an interval 34 for avoiding interference with the vertical movement of the welding head 10 is maintained between the two pressing members 33, and the size of the interval 34 is adjustable. Under the driving action of the second driving mechanism 32, the pressing pieces 33 can be lifted up and down, before welding, the wire harness is firstly contacted with the terminal 51, then the second driving mechanism 32 controls the two pressing pieces 33 to descend, the two pressing pieces 33 are pressed on the wire harness in a pressing mode, therefore, the wire cores of the wire harness can be prevented from being dispersed, and then the first driving mechanism 20 drives the welding head 10 to descend to the positions of the wire harness and the terminal 51, so that welding can be carried out, the welding quality can be guaranteed, and defective products are avoided.
