TECHNICAL FIELD
[0001] The utility model relates to an anvil and ultrasonic welding equipment. BACKGROUND
[0002] Ultrasonic welding is to use high-frequency vibration wave to transmit to the surface of two objects to be welded, under pressure, the surface of two objects rubs each other to form the fusion between molecular layers, ultrasonic welding is to convert 50Hz or 60Hz current into 15KHz, 20KHz, 30KHz or 40KHz current by ultrasonic generator, the converted high-frequency electric energy is converted into mechanical movement of the same frequency by transducer, and then the mechanical movement is transmitted to the welding head through a set of amplitude-changing horn device.
[0003] When ultrasonic wave acts on the contact surface of thermoplastic material, high-frequency vibration of tens of thousands per second is generated, the high-frequency vibration of a certain amplitude is transmitted to the welding area by the upper welding part, local high temperature is generated due to the large acoustic resistance at the welding area, i.e. the interface of two welding, and the material has poor heat conductivity, so the heat cannot be dissipated in time and is accumulated in the welding area, so that the contact surface of two materials is rapidly melted, and after a certain pressure is applied, the two materials are fused into one, when the ultrasonic wave stops acting, the pressure is maintained for several seconds to make the materials solidify and form, so that a solid molecular chain is formed, the welding purpose is achieved, and the welding strength can approach the strength of the original material.
[0004] In the ultrasonic welding equipment, ultrasonic welding can be realized only by the cooperation of the welding head and the anvil, and the welding head and the anvil are one of the key components that determine the quality of welding. Since the anvil is used to support the object to be welded, it is affected by high-frequency vibration, and the working surface of the anvil is worn out after long-term use, which leads to the decline of welding quality. The existing anvil has only one working surface, and when the working surface is worn out, the anvil needs to be replaced, which leads to short service life of the anvil, low utilization rate and high economic cost.
