Description

Technical Field

[0001] The utility model discloses an automobile bumper welding device, belongs to the technical field of ultrasonic welding devices, and specifically relates to an ultrasonic punching welding device for automobile bumpers. Background Art

[0002] Ultrasonic welding equipment is a technology that uses ultrasonic vibration to connect two workpieces together in an instant through hot forming materials. This equipment is usually used for welding materials such as plastics and metals. It uses the heat generated by high-frequency vibration to achieve the welding of materials. It has the advantages of simple operation, high efficiency, and no need for additional heating or adding materials.

[0003] The working principle of ultrasonic welding equipment is to convert electrical energy into high-frequency mechanical vibration, usually above 20 kHz. This high-frequency vibration is transmitted to the joint surface of the workpiece through the welding head, causing internal friction of the material molecules, thereby generating heat and quickly melting the surface layer, and finally firmly connecting the two workpieces together.

[0004] This technology is widely used in the automotive industry, electronic equipment manufacturing, medical device manufacturing and other fields because it can complete high-strength, well-sealed welding in a short time without causing obvious thermal deformation or damage to the workpiece.

[0005] In the prior art, ultrasonic welding equipment is also commonly used for punching holes in automobile bumpers, but traditional ultrasonic welding equipment can only perform independent punching. When punching holes in multiple positions is required, they need to be completed one by one. This punching efficiency is very slow, and the holes on the automobile bumper are mostly symmetrical structures. Punching holes one by one will cause deviations in the punching positions, thereby causing the product to be scrapped. Utility Model Content

[0036] Working principle: When the utility model is working, first, the third cylinder 24 in the product clamping component 2 moves the support frame 20 and the product fixture 26 to the outside. At this time, the staff or the manipulator places the product on the product fixture 26, and at the same time, the pneumatic pre-pressing group 27 fixes the product, and the bonding pre-pressing adjustment component 4 works to calibrate the punching position, and sends the position information to the electrical control cabinet 6, and then the third cylinder 24 in the product clamping component 2 retracts, and the support frame 20 is moved to the specified position, and then the radar detection component 5 works, and the position information is determined by the radar detector, and the information is sent to the electrical control cabinet 6. At this time, the electrical control cabinet 6 confirms that the product has arrived at the specified position and sends the work instruction information to the punching component 3. At this time, the punching component 3 works according to the first cylinder 12 and the hot air gun 33. The hot air gun 33 heats the punching tool 15 and the punching position material. As the first cylinder 12 works, the punching tool 15 punches the bumper position to complete the punching. The pusher group 16 is predicted to reduce the pressure. At the same time, the punching waste moves into the waste through the waste port 17. After the punching is completed, the radar detector confirms again whether the punching is completed and correct, and the electrical control cabinet 6 confirms it. When it is confirmed that the punching is completed, the product clamping component 2 and the punching component 3 are returned, and the next punching work is performed.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
