[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0027] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0028] The following is combined with Figure 1-5 The utility model is described in further detail.

[0029] Reference Figure 1-3, a wire harness ultrasonic welding machine includes: a frame, an ultrasonic welding mechanism and a fixing mechanism are arranged on the frame; the ultrasonic welding mechanism includes an ultrasonic welding head 1, and the top surface of the ultrasonic welding head 1 is a welding station; the fixing mechanism includes a top head 2, a pressure head 3, a side plate 4, a first driving assembly and a second driving assembly, the side plate 4 is arranged on one side of the ultrasonic welding head 1, the top head 2 and the side plate 4 are arranged opposite to each other in the horizontal direction, and the welding station is located between the top head 2 and the side plate 4, the first driving assembly is used to drive the top head 2 close to or away from the side plate 4, and the bottom surface of the top head 2 is in contact with the top surface of the ultrasonic welding head 1. In this way, when in use, the wire harness connection end is placed on the top surface of the ultrasonic welding head 1 (that is, the processing station), and then the first driving assembly drives the top head 2 to The side panel 4 moves on one side to limit the connection end of the wire harness between the top head 2 and the side panel 4. The second driving component drives the pressure head 3 to press from top to bottom toward the top surface of the ultrasonic welding head 1, limiting the connection end of the wire harness between the pressure head 3 and the ultrasonic welding head 1. In this way, the fixation of the wire harness to be welded is completed, and then welding is performed by the ultrasonic welding head 1. A U-shaped clamping space is formed by the ultrasonic welding head 1, the top head 2, the pressure head 3 and the side panel 4. The connection end of the wire harness can be fixed, multiple wire harnesses can be fixed, and the wire harness can be placed in the U-shaped clamping space from one side, or the wire harness to be welded can be extended from both sides of the U-shaped clamping space, thereby achieving wire harness fixation that takes into account multiple welding methods, improving adaptability and reducing production costs.

[0030] Reference Figure 2-3 In order to prevent the operator's fingers or other foreign objects from entering the movement path of the plug 2 during operation, causing personal injury or machine damage, the fixing mechanism also includes a limit block 5, which is arranged on the frame. The limit block 5 is provided with a first limit sliding hole, and one end of the plug 2 is slidably arranged in the first limit sliding hole. In this way, the movement path of the plug 2 and the area driving the plug 2 to move are in a closed state, preventing the operator's fingers or other foreign objects from entering the movement path of the plug 2, thereby improving safety.

[0031] Reference Figure 2-3The fixing mechanism also includes a movable body 6, which is clamped on one side of the ultrasonic welding head 1 so that the movable body 6 can only perform lifting and lowering movements on the movable body 6, the side plate 4 is arranged on the movable body 6, and the pressure head 3 is arranged on the top of the movable body 6. The second driving assembly includes a driving plate 7 and a cylinder 8 arranged on the frame. The cylinder 8 is used to drive the driving plate 7 to slide back and forth horizontally. The driving plate 7 is provided with an arc hole 71 extending in the vertical direction, and a limiting shaft 61 is provided on the movable body 6, which is passed through the arc hole 71; in order to ensure that the movable body 6 is firmly connected to the driving plate 7, a movable groove is provided at the bottom of the movable body 6, and is clamped on the driving plate 7 through the movable groove. In this way, when in use, the cylinder 8 drives the driving plate 7 to reciprocate horizontally, so that the limiting shaft 61 is at different positions of the arc hole 71, thereby causing the movable body 6 to perform lifting and lowering movements, thereby achieving the purpose of driving the pressure head 3 to perform lifting and lowering movements.

[0032] Reference Figure 3-5 Since the horizontal displacement of the plug 2 is different in different welding methods, the pressure head 3 is displaced in the horizontal direction accordingly to achieve the purpose of always fitting the pressure head 3 to the plug 2. In order to achieve this effect, a second limiting sliding hole is provided on the top of the movable body 6, and one end of the pressure head 3 is horizontally slidably provided in the second limiting sliding hole. The sliding direction of the pressure head 3 is consistent with the sliding direction of the plug 2. In this way, the pressure head 3 can slide in the horizontal direction and always contact with the plug 2 during processing. In order to achieve the adaptive movement of the pressure head 3, a limiting rope 31 is connected to the side of the pressure head 3 away from the plug 2. The suspension end of the limiting rope 31 is connected to the frame. When the movable body 6 moves upward When moving, the limiting rope 31 is used to make the pressure head 3 move to the side away from the top head 2. The movable body 6 is provided with a mounting plate 62 on the side of the pressure head 3 away from the top head 2, and an elastic member 32 is provided between the mounting plate 62 and the pressure head 3 (the elastic member 32 can be a spring, one end of the spring is connected to the mounting plate 62, and the other end is connected to the pressure head 3). In this way, when the movable body 6 moves downward, the limiting rope 31 is relaxed, and the pressure head 3 moves horizontally toward the side of the top head 2 under the action of the elastic force of the elastic member 32 until it contacts the top head 2. When the movable body 6 moves upward, the limiting rope 31 is tightened, and the pressure head 3 compresses the elastic member 32 and moves to the side away from the top head 2, thereby realizing the self-compensation function.

[0033] Further optimization is, Figure 3 As shown, during welding, residues may remain at the processing station. In order to clean the residues in time, an air jet 9 is also provided on the frame. The nozzle of the air jet 9 is directed toward the welding station. After processing, the air jet 9 sprays air to the processing station in time to blow out the residues and cool the ultrasonic welding head 1.

[0034] In summary, when in use, the wiring harness connection end is placed on the top surface of the ultrasonic welding head 1, and then the first driving component drives the top head 2 to move toward the side of the side plate 4, and the wiring harness connection end is limited between the top head 2 and the side plate 4. The second driving component drives the pressure head 3 to press from top to bottom toward the top surface of the ultrasonic welding head 1, and the wiring harness connection end is limited between the pressure head 3 and the ultrasonic welding head 1. In this way, the fixation of the wiring harness to be welded is completed, and then welding is performed by the ultrasonic welding head 1. A U-shaped clamping space is formed by the ultrasonic welding head 1, the top head 2, the pressure head 3 and the side plate 4, so that the connection end of the wiring harness can be fixed, and multiple strands of wiring harness can be fixed, and the wiring harness can be placed in the U-shaped clamping space from one side, or the wiring harness to be welded can be extended from both sides of the U-shaped clamping space, thereby achieving wiring harness fixation that takes into account multiple welding methods, improving adaptability and reducing production costs.

However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
